[0017] The entire disclosure of the foregoing applications is hereby incorporated by reference herein.FIELD

[0018] The present disclosure relates to the technical field of atomization, and specifically, to an aerosol-forming product and an aerosol-forming system.BACKGROUND

[0019] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Because the aerosol may be absorbed by a human body through a respiratory system, a new alternative absorption method is provided for users. An atomization device refers to a device that forms an aerosol by heating or ultrasonically processing a stored atomizable medium. The atomizable medium includes a liquid, gel, paste, or solid aerosol-forming material. These mediums may be atomized to deliver an inhalable aerosol to a user, for replacing a conventional product form and absorption mode.

[0020] Generally, the user needs to voluntarily fill the aerosol-forming material before the aerosol-forming material is used for the first time or after the aerosol-forming material is used. However, the filling amount and quality of the aerosol-forming material may be uncontrollable, or other atomized particles may be carried in a filling process, thereby affecting user experience.SUMMARY

[0021] In an embodiment, the present invention provides an aerosol-forming product, comprising: a container, an accommodating cavity configured to accommodate an aerosol-forming material being formed in the container, wherein the aerosol-forming product is configured to generate heat in a magnetic field to heat the aerosol-forming material.BRIEF DESCRIPTION OF THE DRAWINGS

The aerosol-forming material 33 may include a solid, a liquid, a paste, or a gel, or may include any combination of two or more of the solid, the liquid, the paste, and the gel.

[0201] The aerosol-forming material 33 may include one or more of nicotine, a nicotine base, a nicotine salt, a nicotine derivative, and a nicotine analog. The nicotine salt may be selected from the list consisting of: nicotine citrate, nicotine lactate, nicotine pyruvate, nicotine bitartrate, nicotine pectate, nicotine alginate, and nicotine salicylate.

[0202] The aerosol-forming material 33 may include an aerosol-forming agent. The term “aerosol-forming agent” is used for describing any suitable known compound or compound mixture that helps to promote and stabilize formation of an aerosol during use, and is substantially resistant to thermal degradation at a working temperature of the aerosol-forming product 30. Suitable aerosol-forming agents include, but are not limited to: polyols, such as triethylene glycol, 1,3-butylene glycol, and glycerol; esters of polyols, such as glycerol mono-, di- or tri-acetate; and fatty acid esters of mono-, di- or poly-carboxylic acids, such as dimethyldodecanedioate and dimethyltetradecanedioate. Preferably, the aerosol-forming agent is polyols or a mixture thereof, such as triethylene glycol, 1,3-butylene glycol, and glycerol.

[0203] The aerosol-forming material 33 may further include a perfume. The perfume may include a volatile aroma component. In some embodiments, the perfume may include menthol. The term “menthol” is used for indicating any form of an isomer of a compound 2-isopropyl-5-methylcyclohexanol. The perfume may provide an aroma selected from the group consisting of menthol, lemon, vanilla, orange, holly, cherry, and cinnamon. The perfume may include a volatile tobacco perfume compound that is released from the material upon heating.

[0204] The aerosol-forming material 33 may further include tobacco or a tobacco-containing material. For example, the aerosol-forming material 33 may include any one of the following: tobacco leaves, tobacco vein segments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco. Optionally, the aerosol-forming material 33 may include tobacco powder compressed with, for example, glass or ceramic or another suitable inert material. In a preferred embodiment, the aerosol-forming material includes a homogenized tobacco material. The aerosol-forming material 33 may alternatively include a non-tobacco-containing aerosol-forming material.

[0205] In a case that the aerosol-forming material 33 includes a liquid or a gel, in some embodiments, the aerosol-forming product 30 may include an adsorbent carrier. The aerosol-forming material 33 may be coated on the adsorbent carrier or impregnated into the adsorbent carrier. For example, the nicotine compound and the aerosol-forming agent may be combined with water as a liquid formulation. In some embodiments, the liquid formulation may further include a perfume. Such liquid formulations may then be absorbed by the adsorbent carrier or coated onto a surface of the adsorbent carrier. The adsorbent carrier may be a sheet or tablet of a cellulose-based material onto which the nicotine compound and the aerosol-forming agent may be coated or absorbed.

[0206] When the aerosol-forming material 33 includes a solid aerosol-forming material, the solid aerosol-forming material may include one or more forms of pulverized, granulated, powdered, granular, striped, filamentous, fragmented, or laminar solids, including one or more of the following: herbaceous plant leaves, tobacco leaves, tobacco ribs, expanded tobacco, and homogenized tobacco. When the aerosol-forming material 33 includes a plant material, one or more of roots, stems, leaves, flowers, buds, seeds, and the like of a plant may be included.

[0207] Optionally, the solid aerosol-forming material may include tobacco or non-tobacco volatile aroma compounds that are released upon heating of the solid aerosol-forming material. The solid aerosol-forming material may further include one or more capsules, such as capsules including additional tobacco volatile aroma compounds or non-tobacco volatile aroma compounds, and such capsules may melt during heating of the solid aerosol-forming material.

[0208] Optionally, the solid aerosol-forming material may be disposed on a thermally stable carrier or embedded into the thermally stable carrier. The carrier may take the form of powders, granules, pellets, fragments, strips, bars, or sheets. The solid aerosol-forming material may be deposited on a surface of the carrier, for example, in the form of a sheet, a foam, a gel, or a slurry. The solid aerosol-forming material may be deposited on the entire surface of the carrier, or alternatively, may be deposited in a patterned form to provide inconsistent aroma delivery during use.

[0209] In some embodiments, the aerosol-forming product 30 may be adapted to the atomization device 40 detachably. Specifically, the atomization device 40 may include a suction nozzle 10 and a main unit 20 adapted to each other. The suction nozzle 10 is detachably disposed at one end of the main unit 20. An air outlet channel 11 is formed in the suction nozzle 10. The aerosol-forming product 30 is adapted between the suction nozzle 10 and the main unit 20, and is communicated with the air outlet channel 11. The main unit 20 can generate, after being powered on, energy to heat the aerosol-forming material 33 stored in the aerosol-forming product 30. An aerosol formed after the aerosol-forming material 33 is heated may flow out through the air outlet channel 11 for a user to take.

[0210] In some embodiments, the suction nozzle 10, the main unit 20, and the aerosol-forming product 30 are combined together detachably. The aerosol-forming product 30 is pre-loaded with the aerosol-forming material 33. After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the aerosol-forming material 33 may be updated by replacing the aerosol-forming product 30, thereby accurately controlling an amount of the aerosol-forming material 33, ensuring the quality of the aerosol-forming material 33, and avoiding introduction of other impurities in a process of manually adding the aerosol-forming material 33. In addition, because the suction nozzle 10 and the main unit 20 are reusable, use costs of the aerosol-forming system 100 are reduced. After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the aerosol-forming material 33 may alternatively be filled into the aerosol-forming product 30 by using a known filling device / method.

[0211] In some embodiments, one end of the aerosol-forming product 30 may be plugged into the main unit 20, and the other end is butted with the suction nozzle 10. An end of the main unit 20 adapted to the suction nozzle 10 may form a cavity 240 for accommodating the aerosol-forming product 30. An end of the cavity 240 close to the suction nozzle 10 has an insertion port 244. One end of the aerosol-forming product 30 may be inserted into the cavity 240 from the insertion port 244, and the other end of the aerosol-forming product 30 may extend out of the cavity 240 to be adapted to the suction nozzle 10. In other embodiments, alternatively, the other end of the aerosol-forming product 30 may not extend out of the cavity 240. To be specific, the aerosol-forming product 30 may be completely accommodated in the cavity 240. In some other embodiments, the aerosol-forming product 30 may alternatively be inserted into the suction nozzle 10.

[0212] The main unit 20 may be connected to the suction nozzle 10 magnetically, so that the main unit 20 and the suction nozzle 10 can be easily assembled and disassembled. Specifically, the end of the main unit 20 adapted to the suction nozzle 10 has a support portion 211. The cavity 240 may be formed on the support portion 211 and may be disposed coaxially with the support portion 211. The support portion 211 may be made of a material such as plastic, and the support portion 211 may be embedded with at least one magnetic member 26. The at least one magnetic member 26 may be a magnet or a magnetic material that can be attracted by the magnet. The main unit 20 is magnetically connected to the suction nozzle 10 by using the magnetic member 26. Correspondingly, the end of the main unit 20 adapted to the suction nozzle 10 may be provided with at least one magnetic member 16. The at least one magnetic member 16 and the at least one magnetic member 26 are in magnetic fit with each other.

[0213] In this embodiment, there are two magnetic members 26. The two magnetic members 26 may be respectively located at two lateral sides of the support portion 211. Correspondingly, there are two magnetic members 16. The two magnetic members 16 are respectively disposed in a one-to-one correspondence with the two magnetic members 26. It may be understood that in other embodiments, the support portion 211 may alternatively be made of a magnetic metal material, so that the magnetic members 26 are not required. In some other embodiments, the main unit 20 and the suction nozzle 10 may alternatively be connected to each other in another detachable mode such as a screwing connection or a snapping connection.

[0214] The main unit 20 may include a housing 21, and a battery 22, a circuit board 23, and a heating assembly 24 that are disposed in the housing 21. The housing 21 has a cylindrical structure, and has a cross section in various shapes such as a runway shape, an ellipse shape, a circle shape, and a square shape. This is not limited herein. The circuit board 23 is respectively electrically connected to the battery 22 and the heating assembly 24. A control chip and a related control circuit are disposed on the circuit board 23, to implement calculation and control on the device. The battery 22 is configured to supply power to electronic components such as the circuit board 23 and the heating assembly 24. The heating assembly 24 fits the aerosol-forming product 30, and is configured to heat the aerosol-forming material 33 in the aerosol-forming product 30 after being powered on.

[0215] In this embodiment, the battery 22, the circuit board 23, and the heating assembly 24 are respectively accommodated in a lower portion, a middle portion, and an upper portion of the housing 21. In other embodiments, the battery 22, the circuit board 23, and the heating assembly 24 may alternatively be arranged in the housing 21 in another mode. For example, the battery 22 and the circuit board 23 may alternatively be disposed in parallel.

[0216] In this embodiment, the main unit 20 heats the aerosol-forming material 33 by electromagnetic induction. The heating assembly 24 includes an induction heating source 242. The induction heating source 242 is electrically connected to the battery 22, and can generate an electromagnetic field after being powered on, so as to heat a sensor located in the electromagnetic field.

[0217] In this embodiment, the heating assembly 24 has a tube shape, and the cavity 240 is formed in the heating assembly 24. The induction heating source 242 may include an induction coil 2421. The induction coil 2421 may be of a helical tube shape and is disposed around the outside of the cavity 240. The induction coil 2421 may be coaxially disposed with the cavity 240, but is not limited to being coaxially disposed. Further, the heating assembly 24 may further include a holder 241 and a magnetic shield 243 sleeved outside the induction coil 2421. The holder 241 is configured to form the cavity 240, and may be configured to mount and fix the induction coil 2421. The magnetic shield 243 can reduce electromagnetic radiation from the induction coil 2421 to the outside, and can further be configured to fix the induction coil 2421.

[0218] The aerosol-forming product 30 is designed to be engaged with the main unit 20 that is electrically operated and includes the induction heating source 242. The aerosol-forming product 30 includes a sensor material. The sensor material may be coupled to the induction heating source 242 and interact with the induction heating source 242. The term “sensor material” is used for describing a material that may convert electromagnetic energy into heat. When the sensor material is located in the electromagnetic field, the electromagnetic field may generate an eddy current in the sensor material, and the eddy current may heat the sensor material by ohmic or resistive heating, to further heat the aerosol-forming material 33. In a case that the sensor material includes a ferromagnetic material (for example, iron, nickel, or cobalt), the sensor material may be further heated due to a magnetic hysteresis loss.

[0219] The sensor material may be formed of any material that may be heated by induction to enable the aerosol-forming material 33 to form an aerosol. Suitable sensor materials may include one or more of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, nickel-containing compounds, titanium, metal material composites, and the like. Preferably, the sensor material includes metal or carbon. Further, the sensor material may include or consist of a ferrite material. The ferrite material may include ferritic iron, ferromagnetic alloys (for example, ferromagnetic steel or stainless steel), ferromagnetic particles, or ferrite. In some embodiments, the sensor material may include 400-series stainless steel, for example, 410 stainless steel, 420 stainless steel, or 430 stainless steel.

[0220] It may be understood that in some other embodiments, another heat conduction mode such as heat conduction, infrared radiation, ultrasonic waves, microwaves, and plasma may alternatively be used between the heating assembly 24 and the aerosol-forming product 30.

[0221] In some other embodiments, the aerosol-forming product 30 and the suction nozzle 10 may be integrated. The integrated structure formed by the aerosol-forming product 30 and the suction nozzle 10 may be detachably fitted with the main unit 20, thereby avoiding the problem of cleaning the suction nozzle 10. The main unit 20 may be reusable, and main electronic components such as the battery 22, the circuit board 23, and the heating assembly 24 are centralized in the main unit 20, thereby reducing replacement costs.

[0222] In another embodiment, the suction nozzle 10 may alternatively be mounted on the main unit 20 in a movable adaptation mode (including, but not limited to, a mode of rotating or sliding, or a mode of popping up by being pressed). The aerosol-forming product 30 is detachably adapted between the suction nozzle 10 and the main unit 20. The aerosol-forming product 30 is covered or exposed in a mode of rotating or sliding the suction nozzle 10, and the aerosol-forming product 30 may be updated. Alternatively, the aerosol-forming product 30 may be mounted in the cavity 240 in a non-detachable mode, and an opening 311 of the aerosol-forming product 30 is exposed by rotating or sliding the suction nozzle 10, so as to fill the aerosol-forming material 33 through the opening 311. Alternatively, the aerosol-forming product 30 is popped up by pressing and the like or the aerosol-forming product 30 and the suction nozzle 10 are popped up together, to implement update of the aerosol-forming product 30.

[0223] As shown in FIG. 5 to FIG. 7, in this embodiment, the aerosol-forming product 30 is cylindrical, and may include a container 31, a heating element 32, and the aerosol-forming material 33. An accommodating cavity 310 is formed in the container 31. One end of the container 31 has the opening 311 communicating the accommodating cavity 310 with the outside. The aerosol-forming material 33 is disposed in the accommodating cavity 310 and may be communicated with the outside via the opening 311. Outside air may enter the accommodating cavity 310 via the opening 311, and then flow out through the opening 311 by carrying an aerosol formed by atomizing the aerosol-forming material 33. The heating element 32 includes a sensor material or is made of a sensor material, and may be disposed inside or outside the container 31. During use, the aerosol-forming product 30 is engaged with the main unit 20, so that the heating element 32 is located in the electromagnetic field generated by the induction heating source 242. It may be understood that in other embodiments, the aerosol-forming product 30 may alternatively not be provided with the heating element 32, but the aerosol-forming material 33 may be heated by heat conduction, infrared radiation, ultrasonic waves, microwaves, or plasma. In addition, the aerosol-forming product 30 is not limited to being cylindrical, and may alternatively be in another shape such as a square cylindrical shape or an elliptic cylindrical shape.

[0224] The container 31 may include a tubular container side wall 312 and a container bottom wall 313 disposed at one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 define the accommodating cavity 310. The other end of the container side wall 312 is opened to form an opening 311. The heating element 32 and the aerosol-forming material 33 may be loaded into the accommodating cavity 310 from the opening 311. The container bottom wall 313 may be configured to support the heating element 32 and the aerosol-forming material 33.

[0225] The container 31 may be made of a high temperature resistant material, such as glass, ceramics, metal, plastic, or aluminum foil. Further, the container 31 may be at least partially formed of a transparent material. The term “transparent” is used for describing such a material: The material allows to be passed through by at least a significant proportion of incident light, so that the material can be seen through. In the present disclosure, the substantially transparent material may allow to be passed through by sufficient light, so that the aerosol-forming material 33 in the accommodating cavity 310 is visible before being atomized. In a case that the aerosol-forming material 33 in the accommodating cavity 310 may be transparent, the substantially transparent material may allow smoke or one or more other aerosols formed by the aerosol-forming material 33 to be visible during inhaling of the aerosol-forming product 30.

[0226] The container 31 may be completely transparent. Alternatively, the container 31 may have a relatively low level of transparency, and can still transmit sufficient light, so that the aerosol-forming material 33 in the accommodating cavity 310 is visible before being atomized, or smoke or one or more other aerosols formed by the aerosol-forming material 33 are visible.

[0227] Further, the container 31 may include one or more regions formed of a transparent material, so that a part of the aerosol-forming material 33 is visible via the one or more regions. In addition, the region formed of the transparent material may be colorful, colored, or colorless.

[0228] The heating element 32 may include a ferromagnetic metal material or be made of a ferromagnetic metal material. The heating element 32 may be disposed in the container 31. On one hand, the heating element 32 can be in direct contact with the aerosol-forming material 33, and heat generated by the heating element 32 can be directly transferred to the aerosol-forming material 33, thereby improving heat transfer efficiency. On the other hand, the container 31 can have a thermal insulation function, thereby reducing heat transferred by the heating element 32 to the outside.

[0229] The shape of the heating element 32 is not limited. For example, the heating element may have various shapes such as a sheet shape, a tube shape, a barrel shape, and a helical shape. In some implementations, the heating element 32 may be disposed in the container 31 detachably. Therefore, the heating element 32 may alternatively be used as a disposable consumable. The heating element 32 may be separately replaced, thereby avoiding a cleaning problem. In addition, the structure of the heating element 32 is simple and cheap, and replacement costs are relatively low. In another implementation, the heating element 32 may alternatively be disposed in the container 31 in a non-detachable mode. It should be noted that, non-detachable means that the container 31 or the heating element 32 cannot be disassembled without being damaged, so as to be forcibly replaced.

[0230] In some embodiments, a heating cavity 320 may be formed in the heating element 32. The aerosol-forming material 33 is accommodated in the heating cavity 320. Specifically, in this embodiment, the heating element 32 is a cylindrical metal barrel, and may include a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. The heating side wall 321 and the heating bottom wall 322 jointly define the heating cavity 320. The heating bottom wall 322 may be supported on the container bottom wall 313. An opening 323 is formed at an end of the heating element 32 opposite to the heating bottom wall 322. The aerosol-forming material 33 may be loaded into the heating element 32 via the opening 323 and supported on the heating bottom wall 322. During assembly, the aerosol-forming material 33 may be first filled in the heating element 32, and then placed in the container 31 together. Alternatively, the heating element 32 may be first placed in the container 31, and then the heating element 32 is filled with the aerosol-forming material 33.

[0231] An outer diameter of the heating side wall 321 is smaller than an inner diameter of the container side wall 312. On one hand, the heating element 32 may be more easily assembled into the container 31. On the other hand, a clearance 3210 may be formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, to facilitate thermal insulation and reduce heat transferred by the heating side wall 321 to the container side wall 312.

[0232] In some embodiments, the clearance 3210 may be an annular clearance having a capillarity action. After the aerosol-forming material 33 is liquefied in a heating process, the liquid aerosol-forming material 33 can enter the clearance 3210 through a through hole 3220 provided in the heating element 32, thereby avoiding other defects that affect an atomization effect, such as generation of odor due to excessively high temperature between the heating side wall 321 of the heating element 32 and the container 31. It may be understood that in other embodiments, the clearance 3210 may alternatively have a non-capillarity structure, or some regions have a non-capillarity structure and some regions have a capillarity structure.

[0233] There may be one or more through holes 3220, which may be provided in the heating side wall 321 and / or the heating bottom wall 322 of the heating element 32. In some embodiments, the hole diameter of the through hole 3220 may be 0.5 mm to 1.5 mm. Within this range, it is possible not only to prevent the pasty aerosol-forming material 33 from flowing out of the through hole 3220, but also to enable the liquefied aerosol-forming material 33 to flow out of the through hole 3220. In addition, the through hole 3220 may further be configured to add the aerosol-forming material 33. For example, the aerosol-forming material 33 may be added to the container 31 through the through hole 3220 by injection. In other embodiments, the heating element 32 may alternatively not be provided with the through hole 3220.

[0234] In other embodiments, an outer wall surface of the heating side wall 321 and an inner wall surface of the container side wall 312 may adopt a fit mode such as transition fit or interference fit, partial clearance fit or partial interference fit.

[0235] It may be understood that in other embodiments, the heating element 32 is not limited to the foregoing structural shape. For example, the heating side wall 321 may alternatively have a tapered tube shape or a step tube shape. For another example, the heating element 32 may be a circular tube, a tapered tube, or a step tube not having the heating bottom wall 322, or may be in another shape such as a U-shaped sheet. In addition, in some other embodiments, the heating element 32 may be disposed on an outer side of the container 31. Alternatively, the heating element 32 may be partially disposed on an outer side of the container 31. Alternatively, the heating element 32 may be integrally disposed with the container 31.

[0236] In some embodiments, an inner surface of the heating element 32 may further be provided with an isolating layer. The isolating layer may include a ceramics enamel layer or a glass enamel layer. The heating element 32 is isolated from the aerosol-forming material 33 by using the isolating layer, so that an odor that may be generated in a heating process can be further avoided. The through hole 3220 provided in the heating element 32 can further enable the inner surface of the heating element 32 to be more easily plated with the enamel layer in a process of enameling, thereby ensuring that the heating element 32 is uniformly plated with the enamel layer.

[0237] Further, in some embodiments, the aerosol-forming product 30 further includes a sealing member 35. The sealing member 35 is disposed at the opening 311 of the container 31, and is configured to seal the opening 311, thereby preventing the aerosol-forming material 33 in the container 31 from flowing out, preventing external impurities from entering the container 31, and ensuring cleanness inside the container 31. In this embodiment, the sealing member 35 includes a sealing film 351. The sealing film 351 is adhered to a peripheral edge of the opening 311 in a tearing mode so as to seal the opening 311. During use, the sealing film 351 may be first torn off, to expose the opening 311. In some embodiments, the sealing film 351 may include a body portion 3511 covering the container 31 and a protrusion portion 3512 extending outward from an edge of the body portion 3511. The protrusion portion 3512 extends out of the container 31, so that a user tears off the sealing film 351 by pinching the protrusion portion 3512. In other embodiments, the sealing film 351 may alternatively be pierced to expose the opening 311.

[0238] In other embodiments, the sealing member 35 may alternatively include another sealing structure. For example, the sealing member 35 may include a thin-walled structure that can be pierced, or may include a sealing plug plugged in the opening 311, or may include a sealing cover covering the opening 311.

[0239] In some embodiments, the aerosol-forming product 30 may further include a limiting member 34 disposed in the container 31. The limiting member 34 is disposed between the sealing member 35 and the aerosol-forming material 33, and is configured to prevent the aerosol-forming material 33 from flowing to the sealing member 35 to cause waste. The limiting member 34 may be made of a high temperature resistant material, such as metal or non-metal. Further, the limiting member 34 may be made of a material incapable of heating by induction of a magnetic field, so as to prevent dry heating of the limiting member 34 caused by the fact that an amount of the aerosol-forming material 33 is reduced and is not in contact with the limiting member 34. In other embodiments, the limiting member 34 may alternatively be made of a metal material capable of heating by induction of the magnetic field.

[0240] The limiting member 34 may be disposed on an outer side of the heating element 32 or may be disposed in the heating element 32, and / or the limiting member 34 and the heating element 32 may be disposed integrally or may be disposed separately. In this embodiment, the limiting member 34 includes a mesh 341. The mesh 341 may be a metal mesh. The metal mesh has advantages such as high temperature resistance, no pollution, no odor, and low costs. The mesh 341 is formed with a plurality of airflow through holes 3410. The airflow through holes 3410 have a hole diameter in a suitable range, can allow passage of airflow, and can prevent the aerosol-forming material 33 from flowing out of the airflow through holes 3410. In addition, the mesh 341 can further prevent the aerosol-forming material 33 from splashing out when the aerosol-forming material 33 is heated. In other embodiments, the limiting member 34 may further include a hot melt film. The hot melt film can be automatically cracked or burned after being heated, is non-toxic, has no odors, and has no pollution.

[0241] In this embodiment, the mesh 341 is disposed on an outer side of the heating element 32 and abuts against an upper end surface of the heating element 32, so as to press the heating element 32 against the container bottom wall 313. At least a part of an outer wall surface of the mesh 341 is in contact with an inner wall surface of the container 31, so as to fix the mesh 341 in the container 31. Further, at least a part of the outer wall surface of the mesh 341 is in interference fit with the inner wall surface of the container 31, and the mesh 341 is fixed in the container 31 by using the interference fit. The fixing mode has a simple structure, is easy to be implemented, and is highly reliable.

[0242] In some embodiments, the mesh 341 may include a sheet-like body 3411 and a plurality of limiting flanges 3412 extending outward from an outer edge of the sheet-like body 3411. The plurality of airflow through holes 3410 may be evenly distributed on the sheet-like body 3411 in an array, for even passage of airflow. The plurality of limiting flanges 3412 may be evenly spaced apart along a peripheral direction of the sheet-like body 3411, so that the mesh 341 is evenly stressed. An outer diameter of the sheet-like body 3411 is smaller than the inner diameter of the container side wall 312. The mesh 341 is in interference fit with the container side wall 312 via the plurality of limiting flanges 3412, to facilitate loading of the mesh 341 into the container 31. It may be understood that in other embodiments, the mesh 341 may alternatively not be provided with the limiting flange 3412, but is in direct interference fit with the container side wall 312 by using the sheet-like body 3411.

[0243] Further, as shown in FIG. 3, FIG. 4, and FIG. 6, the air outlet channel 11 and the air inlet channel 12 are formed in the suction nozzle 10. Outside air may enter the accommodating cavity 310 via the air inlet channel 12, and then flow out through the air outlet channel 11 by carrying an aerosol formed by atomizing the aerosol-forming material 33. It may be understood that in other embodiments, the air inlet channel 12 may alternatively be formed in the main unit 20, or partially formed in the suction nozzle 10 and partially formed in the main unit 20, or at least a part of the air inlet channel 12 may be formed between the suction nozzle 10 and the main unit 20.

[0244] In some embodiments, the suction nozzle 10 may include an air guide tube 13. The air guide tube 13 may be made of a high temperature resistant material, such as metal or high temperature resistant plastic (for example, polyetheretherketone). An inner wall surface of the air guide tube 13 defines an air guide channel 130. The air guide channel 130 may be configured for air inlet or air outlet.

[0245] In this embodiment, the air guide tube 13 is made of a non-ferromagnetic material. The air guide tube 13 may extend along a longitudinal direction and may be disposed coaxially with the opening 311 and the accommodating cavity 310. A lower end of the air guide tube 13 may extend into the opening 311, and may further extend through the opening 311 into the accommodating cavity 310. The end of the air guide tube 13 extending into the accommodating cavity 310 is spaced apart from the mesh 341 and / or the aerosol-forming material 33. An outer diameter of the air guide tube 13 is smaller than an inner diameter of the opening 311, so that an annular vent clearance 3111 is formed between an outer wall surface of the air guide tube 13 and an inner wall surface of the opening 311. The vent clearance 3111 may be configured for passage of airflow. One of the vent clearance 3111 and the air guide channel 130 is configured for air inlet, and the other is configured for air outlet. It may be understood that in other embodiments, the air guide tube 13 and the opening 311 may alternatively not be disposed coaxially.

[0246] In some embodiments, the air inlet channel 12 may include at least one lateral airway 121 communicated with the outside and at least one central airway 122 communicating the at least one lateral airway 121 with the accommodating cavity 310. Specifically, in this embodiment, there are two lateral airways 121, to ensure sufficient air inlet. The two lateral airways 121 may be respectively symmetrically disposed on two opposite sides of the suction nozzle 10. Each lateral airway 121 extends transversely inward from an outer side surface of the suction nozzle 10. There is one central airway 122. The central airway 122 extends longitudinally and may be disposed coaxially with the accommodating cavity 310. Longitudinal ends of the central airway 122 are respectively communicated with the lateral airways 121 and the accommodating cavity 310. More specifically, in this embodiment, the central airway 122 is formed by the air guide channel 130.

[0247] The air outlet channel 11 may include an exhaust channel 112 communicated with the outside and a communication channel 111 communicating the accommodating cavity 310 with the exhaust channel 112. The exhaust channel 112 may extend longitudinally downward from a top surface of the suction nozzle 10. The communication channel 111 is disposed outside the air guide tube 13. The aerosol formed by atomizing the aerosol-forming material 33 may flow out through the vent clearance 3111, the communication channel 111, and the exhaust channel 112 in sequence from bottom to top.

[0248] The specific structure of the communication channel 111 may be flexibly designed according to requirements. For example, the communication channel 111 may include an annular airway surrounding the air guide tube 13. For another example, the communication channel 111 may alternatively include a plurality of peripheral airways spaced apart along a peripheral direction of the air guide tube 13.

[0249] In some embodiments, a flow blocking structure may be further disposed in the air outlet channel 11. The flow blocking structure is configured to block a part of the air outlet channel 11, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 after being heated. The mesh 341 disposed in the accommodating cavity 310 may alternatively prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 after being heated.

[0250] Further, in some embodiments, a side wall of the suction nozzle 10 may be further provided with an auxiliary airflow hole. The auxiliary airflow hole is communicated with the communication channel 111. In an atomization process, air in an external environment may further flow from the auxiliary airflow hole into the communication channel 111, and then may be mixed with the aerosol in the communication channel 111 to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing out of the suction nozzle 10 is adjusted.

[0251] In some embodiments, the aerosol-forming system 100 may further include a sensor 14 electrically connected to the circuit board 23. The sensor 14 is at least partially disposed in the air outlet channel 11. In one embodiment, the sensor 14 is a temperature sensor, configured to detect a temperature of the air flow in the air outlet channel 11, and transmit temperature data to the circuit board 23. A related control circuit is disposed on the circuit board 23, and can control a heating power of the heating assembly 24 according to the temperature data, and can determine, according to the temperature data, whether dry heating occurs. In this embodiment, the sensor 14 is a thermocouple, and may be disposed at one end of the exhaust channel 112 close to the communication channel 111. In other embodiments, the sensor 14 may alternatively use another sensor structure such as a thermistor, and / or the sensor 14 may alternatively be disposed at another position of the air outlet channel 11.

[0252] In other embodiments, the sensor 14 may alternatively include a pressure sensor for detecting a pressure in the air outlet channel 11, or a counting sensor for recording a quantity of inhalations. To reduce replacement costs of the sensor 14, the sensor 14 may alternatively be disposed in the main unit 20. Specifically, a part of the air outlet channel 11 may be disposed in the main unit 20, and the sensor 14 is disposed in the part of the air outlet channel 11 in the main unit 20.

[0253] Further, the suction nozzle 10 further includes two first electrodes 15 electrically connected to the sensor 14. The main unit 20 further includes two second electrodes 25 electrically connected to the circuit board 23. The two first electrodes 15 and the two second electrodes 25 respectively conduct each other in a contact conduction mode. When the suction nozzle 10 is separated from the main unit 20, the first electrodes 15 are separated from the second electrodes 25. After the suction nozzle 10 is adapted to the main unit 20, the first electrodes 15 abut against the second electrodes 25 for conduction, so as to electrically connect the sensor 14 to the circuit board 23. In this embodiment, the first electrodes 15 and the second electrodes 25 are both electrode columns, and the first electrodes 15 and / or the second electrodes 25 have elasticity, to improve reliability of electrical connection. In other embodiments, the first electrodes 15 and / or the second electrodes 25 may alternatively include another conductive connection structure such as a conductive elastic sheet. In addition, the quantity of the first electrodes 15 and the quantity of the second electrodes 25 are not limited to two.

[0254] FIG. 8 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment is also cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, a mesh 341, and a sealing film 351.

[0255] Different from the aerosol-forming product 30 in the foregoing embodiment, the container 31 in this embodiment is an aluminum foil paper tube open at two ends. Because the container 31 in this embodiment does not have the container bottom wall 313 that can play a supporting function, at least a part of an outer wall surface of the heating element 32 may be in interference fit with an inner wall surface of the container 31, so that the heating element 32 is fixed in the container 31 by using the interference fit. Further, to reduce the amount of heat transferred by the heating element 32 to the container 31 and avoid scorching of the paper tube, a mode in which a part of the outer wall surface of the heating element 32 is in interference fit with the inner wall surface of the container 31 and a part of the outer wall surface is in clearance fit with the inner wall surface of the container 31 may be used. A bottom end of the heating element 32 away from the mesh 341 may extend out of the container 31, or may not extend out of the container 31.

[0256] The heating element 32 is a metal barrel and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. In some embodiments, the heating side wall 321 may include a first side wall 3211 close to one end of the heating bottom wall 322 and a second side wall 3212 away from one end of the heating bottom wall 322. An outer diameter of the second side wall 3212 may be greater than an outer diameter of the first side wall 3211. According to a first aspect, an outer peripheral surface of the second side wall 3212 is in interference fit with an inner peripheral surface of the container 31, to fix the heating element 32 in the container 31. According to a second aspect, an outer peripheral surface of the first side wall 3211 is in clearance fit with the inner peripheral surface of the container 31, so as to reduce the amount of heat transferred by the heating element 32 to the container 31, thereby avoiding scorching of the paper tube. According to a third aspect, the aerosol-forming material 33 is mainly disposed in the first side wall 3211 close to the heating bottom wall 322. The first side wall 3211 is a main heating region. The first side wall 3211 is set to be in clearance fit with the container 31, and the second side wall 3212 is set to be in interference fit with the container 31. This is more beneficial to reducing heat transferred by the heating element 32 to the container 31.

[0257] The mesh 341 may be supported on an upper end surface of the heating element 32. An outer peripheral surface of the mesh 341 is in interference fit with the inner peripheral surface of the container 31, thereby fixing the mesh 341 in the container 31.

[0258] For the structure of the sealing film 351, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0259] FIG. 9 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment is also cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, a mesh 341, and a sealing member 35. For structures of the container 31 and the mesh 341, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0260] Similarly, the heating element 32 in this embodiment is also a metal barrel and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. Different from the foregoing embodiment, at least one protrusion 324 is formed on the heating bottom wall 322 in this embodiment. The heating bottom wall 322 abuts against the container bottom wall 313 of the container 31 by using the at least one protrusion 324, so that a direct contact area between the heating bottom wall 322 and the container bottom wall 313 can be reduced, and the amount of heat transferred by the heating element 32 to the container 31 can be reduced.

[0261] In addition, different from the foregoing embodiment, the sealing member 35 in this embodiment includes a sealing plug 352. The sealing plug 352 is detachably plugged into the container 31, thereby sealing or unsealing the opening 311.

[0262] In some embodiments, the sealing plug 352 may be made of a soft material such as silica gel, and may include a sealing portion 3522 disposed in the opening 311 in a sealing mode. The sealing plug 352 may further include an exposure portion 3521 and an extension portion 3523 that are respectively disposed at two ends of the sealing portion 3522. The exposure portion 3521 extends outward from one end of the sealing portion 3522 away from the accommodating cavity 310. The exposure portion 3521 is at least partially exposed outside the opening 311, to facilitate a user to pull out the sealing plug 352. The extension portion 3523 extends inward from the sealing portion 3522 towards one end of the accommodating cavity 310. An end of the extension portion 3523 away from the sealing portion 3522 may be pressed against the mesh 341, so as to press the mesh 341 and the heating element 32 against the container bottom wall 313, thereby avoiding sway of the mesh 341 and the heating element 32 in the container 31 during transportation of the aerosol-forming product 30. In other embodiments, the end of the extension portion 3523 away from the sealing portion 3522 may alternatively be spaced apart from the mesh 341. An outer diameter of the extension portion 3523 may be smaller than an inner diameter of the container 31, to reduce force required for assembling the sealing plug 352 into the container 31.

[0263] It may be understood that in other embodiments, the sealing plug 352 may alternatively be connected to the container 31 in a non-detachable mode. At this moment, a vent hole for airflow circulation may be provided in the sealing plug 352.

[0264] FIG. 10 to FIG. 11 show an aerosol-forming product 30 according to some embodiments of the present disclosure. A mesh 341 in this embodiment is disposed in a heating element 32.

[0265] The mesh 341 may include a sheet-like body 3411 and a plurality of limiting flanges 3412 extending outward from an outer edge of the sheet-like body 3411. The sheet-like body 3411 is provided with a plurality of airflow through holes 3410. The plurality of limiting flanges 3412 may be evenly spaced apart along a peripheral direction of the sheet-like body 3411.

[0266] The heating element 32 is a metal barrel and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. At least one protrusion 324 is formed on an outer surface of the heating bottom wall 322. The heating bottom wall 322 abuts against the container bottom wall 313 of the container 31 by using the at least one protrusion 324, so that a direct contact area between the heating bottom wall 322 and the container bottom wall 313 can be reduced, and the amount of heat transferred by the heating element 32 to the container 31 can be reduced.

[0267] In some embodiments, the heating side wall 321 may include a first side wall 3211 close to one end of the heating bottom wall 322 and a second side wall 3212 away from one end of the heating bottom wall 322. An outer diameter of the second side wall 3212 is greater than an outer diameter of the first side wall 3211, and an outer peripheral surface of the first side wall 3211 is in clearance fit with an inner peripheral surface of the container 31, so as to reduce the amount of heat transferred by the heating element 32 to the container 31.

[0268] An inner diameter of the second side wall 3212 is greater than an inner diameter of the first side wall 3211, so that a step surface 321d is formed at an inner joint between the second side wall 3212 and the first side wall 3211. The mesh 341 may be disposed in the second side wall 3212 and abut against the step surface 321d. Further, in some embodiments, a plurality of clamping slots 3214 may be formed on the second side wall 3212 and respectively correspond to the plurality of limiting flanges 3412. The plurality of limiting flanges 3412 may be respectively clamped in the plurality of clamping slots 3214, to fix the mesh 341 in the second side wall 3212.

[0269] The heating element 32 may be fixed peripherally in the container 31 by using an interference fit between the limiting flanges 3412 and the container side wall 312, or by using an interference fit between the second side wall 3212 and the container side wall 312.

[0270] FIG. 12 to FIG. 13 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment is cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, and a sealing plug 352. For structures of the container 31 and the sealing plug 352, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0271] In this embodiment, the heating element 32 is a metal barrel and is mounted in the container 31 in an inverted mode. Specifically, the heating element 32 includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. The heating bottom wall 322 is located at an end of the heating side wall 321 away from the container bottom wall 313. At least one vent hole 3221 for airflow circulation is further provided in the heating bottom wall 322, so that outside air can enter the heating element 32, and then flow out by carrying an aerosol formed by atomizing the aerosol-forming material 33 in the heating element 32. Further, to ensure even airflow, a plurality of vent holes 3221 evenly arranged in an array may be provided in the heating bottom wall 322. Each vent hole 3221 have a hole diameter in a suitable range, thereby preventing the aerosol-forming material 33 from flowing out of the vent hole 3221.

[0272] An opening 323 is formed at an end of the heating side wall 321 opposite to the heating bottom wall 322. When the aerosol-forming product 30 is assembled, the heating bottom wall 322 of the heating element 32 may be first placed downward, so that the opening 323 faces upward. Then the aerosol-forming material 33 is injected into the heating element 32 by an injection apparatus via the opening 323. Because the hole diameter of the vent holes 3221 is relatively small and the pasty aerosol-forming material 33 has particular viscosity, it is not easy for the aerosol-forming material 33 to flow out of the vent holes 3221. The aerosol-forming material 33 is injected into the heating element 32, and then the heating element 32 is inverted into the container 31, so that the opening 323 of the heating element 32 faces toward the container bottom wall 313, and the heating bottom wall 322 faces away from the container bottom wall 313.

[0273] It may be understood that in this embodiment, the heating bottom wall 322 can play a role of the mesh 341 in the foregoing embodiment. Therefore, the mesh 341 is not additionally required for the aerosol-forming product 30 in this embodiment, thereby reducing costs.

[0274] FIG. 14 to FIG. 15 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-forming material 33, a sealing film 351, a sealing plug 352, and a fixing member 36.

[0275] The container 31 is a cylindrical glass tube and may include a tubular container side wall 312 and a container bottom wall 313 disposed at one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define an accommodating cavity 310 having an opening 311 at one end. The aerosol-forming material 33 is disposed in the accommodating cavity 310.

[0276] The heating element 32 is disposed in the accommodating cavity 310 and is at least partially in contact with the aerosol-forming material 33. The heating element 32 can generate heat by induction of a magnetic field in an electromagnetic environment, so as to heat the aerosol-forming material 33. In this embodiment, the heating element 32 is approximately U-shaped and may include a heating bottom wall 322 and two heating side walls 321 respectively extending upward from two transverse ends of the heating bottom wall 322. The heating bottom wall 322 has a sheet shape and may be supported on the container bottom wall 313. The two heating side walls 321 are respectively located at two side edges of the length of the heating bottom wall 322 and may be perpendicular to the heating bottom wall 322. The length of the heating bottom wall 322 is smaller than the inner diameter of the container side wall 312. On one hand, the heating element 32 may be more easily assembled into the container 31. On the other hand, a clearance may be formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, to facilitate thermal insulation and reduce heat transferred by the heating side wall 321 to the container side wall 312.

[0277] The aerosol-forming material 33 is at least partially disposed between the two heating side walls 321. In this embodiment, the aerosol-forming material 33 is in contact with inner wall surfaces and outer wall surfaces of the two heating side walls 321, and the heating bottom wall 322, so that a contact area between the aerosol-forming material 33 and the heating element 32 is relatively large, thereby facilitating heat transfer from the heating element 32 to the aerosol-forming material 33.

[0278] It may be understood that in other embodiments, the heating element 32 is not limited to the foregoing structural shape. For example, the heating side wall 321 may be not perpendicular to the heating bottom wall 322, and / or the quantity of the heating side walls 321 may be three or more. There may alternatively be only one heating side wall 321. For example, the heating element 32 is a sheet structure having an inverted T shape.

[0279] In some embodiments, an inner surface and / or an outer surface of the heating element 32 may further be provided with an isolating layer. The isolating layer may include a ceramics enamel layer or a glass enamel layer. The heating element 32 can be isolated from the aerosol-forming material 33 by the isolating layer, so that an odor that may be generated in a heating process can be further avoided. A through hole 3220 may be further provided in the heating side wall 321 and / or the heating bottom wall 322. By providing the through hole 3220, the surface of the heating side wall 321 and / or the heating bottom wall 322 can be more easily be plated with an enamel layer in the process of enameling, thereby ensuring that the heating element 32 is evenly plated with the enamel layer. It may be understood that in other embodiments, the heating element 32 may alternatively not be provided with the through hole 3220.

[0280] The fixing member 36 is disposed in the container 31, is configured to fix the heating element 32 in the container 31 in a peripheral direction, and may be made of a high temperature resistant material, such as metal or non-metal. Further, the fixing member 36 may be disposed between the sealing plug 352 and the aerosol-forming material 33, and the fixing member 36 may further reduce waste caused by flowing of the aerosol-forming material 33 to the sealing plug 352. In some embodiments, the fixing member 36 may be made of a material incapable of heating by induction of a magnetic field, so as to prevent dry heating of the fixing member 36 caused by the fact that an amount of the aerosol-forming material 33 is reduced and is not in contact with the fixing member 36. In other embodiments, the fixing member 36 may alternatively be made of a metal material capable of heating by induction of the magnetic field.

[0281] In this embodiment, the fixing member 36 is in a sheet shape and is made of a metal material. The metal material has advantages such as high temperature resistance, no pollution, no odor, and low costs. At least a part of an outer wall surface of the fixing member 36 is in interference fit with the inner wall surface of the container 31, and the fixing member 36 is fixed in the container 31 by using the interference fit.

[0282] The fixing member 36 is provided with a flow through hole 360 for passage of airflow and a via 361 for penetration of the heating side wall 321. In this embodiment, the flow through hole 360 is located in the middle of the fixing member 36. There are two vias 361 respectively located on two opposite sides of the via 361. The heating side wall 321 may include a first side wall 3211 extending upward from the heating bottom wall 322 and a second side wall 3212 extending upward from the first side wall 3211. The width of the first side wall 3211 may be equal to the width of the heating bottom wall 322 and greater than the width of the second side wall 3212. The width of the first side wall 3211 is relatively large, so as to enlarge a heating area. The second side wall 3212 penetrates in the via 361, and a lower end surface of the fixing member 36 may abut against an upper end surface of the first side wall 3211.

[0283] It may be understood that in other embodiments, the aerosol-forming product 30 may alternatively not be provided with the fixing member 36, and the heating element 32 is fixed in the container 31 by using another structure. For example, an angle between the heating side wall 321 and the heating bottom wall 322 may be set to an obtuse angle, so that an upper end of the heating side wall 321 flares outward to abut against the inner wall surface of the container 31. For another example, the heating element 32 is made of a thermal phase change material. The heating element 32 can be in interference fit with the container 31 after being subject to thermal expansion, thereby implementing fixing of the heating element 32 in the container 31.

[0284] The sealing plug 352 is at least partially disposed in the opening 311 in a sealing mode to sealing the opening 311. Generally, at least a part of an outer wall surface of the sealing plug 352 may be in sealing fit, such as interference fit, with the inner wall surface of the opening 311. The sealing plug 352 may be made of a soft material such as silica gel, so as to improve the sealing performance of the sealing plug 352 and enable the sealing plug 352 to be more easily assembled into the container 31. In other embodiments, the sealing plug 352 may alternatively be made of a material having certain hardness, such as plastic. Further, the sealing plug 352 may be at least partially formed of a transparent material.

[0285] At least one vent channel 3524 communicating the accommodating cavity 310 to the outside atmosphere is further formed in the sealing plug 352 and / or between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31. In this embodiment, the at least one vent channel 3524 includes at least one air inlet channel 3525 and at least one air outlet channel 3526. After the suction nozzle 10, the main unit 20, and the aerosol-forming product 30 are assembled, the at least one air inlet channel 3525 communicates the accommodating cavity 310 with the air inlet channel 12. The at least one air outlet channel 3526 communicates the accommodating cavity 310 with the air outlet channel 11. In other embodiments, the at least one vent channel 3524 may alternatively include only an air inlet channel or an air outlet channel, and air outlet or air inlet from the accommodating cavity 310 may be implemented by providing a vent hole on a side wall of the container 31.

[0286] Preferably, a cross-sectional area of the at least one air inlet channel 3525 is not smaller than a cross-sectional area of the at least one air outlet channel 3526, to ensure sufficient air inlet, and ensure that the aerosol formed by atomizing the aerosol-forming material 33 can be sufficiently carried out by airflow. The cross-sectional area of a single air inlet channel 3525 or air outlet channel 3526 is relatively small, so that the aerosol-forming material 33 having a specific viscosity does not easily leak out of the air inlet channel 3525 or the air outlet channel 3526.

[0287] In this embodiment, the at least one air inlet channel 3525 and the at least one air outlet channel 3526 are both formed in the sealing plug 352. Specifically, one air inlet channel 3525 and a plurality of air outlet channels 3526 are formed in the sealing plug 352. The air inlet channel 3525 is located in the middle of the sealing plug 352. The plurality of air outlet channels 3526 are distributed on the outer periphery of the air inlet channel 3525. A cross-sectional area of the air inlet channel 3525 is not smaller than a total cross-sectional area of the plurality of air outlet channels 3526, to ensure sufficient air inlet, and ensure that the aerosol formed by atomizing the aerosol-forming material 33 can be sufficiently carried out.

[0288] Further, in this embodiment, the air inlet channel 3525 is a circular hole having a hole diameter of 2.5 mm to 3.5 mm. Alternatively, the cross-sectional area of the air inlet channel 3525 may be 4.5 mm2 to 10 mm2. Within this range, not only sufficient air inlet can be ensured, but also the aerosol-forming material 33 can be effectively prevented from leaking out of the air inlet channel 3525. The air outlet channels 3526 are waist-shaped holes. The plurality of air outlet channels 3526 are evenly spaced apart around the outer periphery of the air inlet channel 3525. The total cross-sectional area of the plurality of air outlet channels 3526 may be 2 mm2 to 9 mm2, to ensure smooth airflow circulation.

[0289] It may be understood that in other embodiments, the shapes of the air inlet channel 3525 and the air outlet channels 3526 are not limited to the foregoing shapes. In addition, the quantities and distribution modes of the air inlet channel 3525 and the air outlet channel 3526 are also not limited. For example, there is one air outlet channel 3526, and there are a plurality of air inlet channels 3525 distributed on the outer periphery of the air outlet channel 3526. For another example, there are a plurality of air outlet channels 3526 and a plurality of air inlet channels 3525. The plurality of air outlet channels 3526 may be distributed on the outer periphery or the inner periphery of the plurality of air inlet channels 3525.

[0290] The sealing plug 352 may include a sealing portion 3522 and an extension portion 3523 extending downward from the sealing portion 3522. There is a spacing between a lower end surface of the extension portion 3523 and the aerosol-forming material 33. An outer wall surface of the sealing portion 3522 is in sealing fit with the inner wall surface of the container side wall 312. The container side wall 312 may further be contracted to form a necking structure 3121. An inner diameter of the necking structure 3121 is smaller than an outer diameter of the sealing portion 3522, so that a lower end surface of the sealing portion 3522 may abut against the necking structure 3121. The necking structure 3121 can limit an axial position of the sealing portion 3522, and prevent the sealing portion 3522 from moving downward. An inner flange 3122 may be formed by extending an upper end inner wall surface of the container side wall 312. The inner flange 3122 can prevent the sealing portion 3522 from moving upward. The inner flange 3122 matches with the necking structure 3121, to clamp and fix the sealing portion 3522.

[0291] An outer diameter of the extension portion 3523 is smaller than the inner diameter of the container 31, so that an annular airflow channel 3520 is formed between an outer wall surface of the extension portion 3523 and the inner wall surface of the container 31. The air inlet channel 3525 may extend longitudinally downward from an upper end surface of the sealing portion 3522 to the lower end surface of the extension portion 3523. The air outlet channel 3526 may extend longitudinally downward from the upper end surface of the sealing portion 3522 to a lower end surface of the sealing portion 3522 and be communicated with the airflow channel 3520. This structure enables a lower air outlet of the air inlet channel 3525 to be closer to the aerosol-forming material 33 than a lower air outlet of the air outlet channel 3526. The extension portion 3523 can guide outside air to the aerosol-forming material 33 and mix the outside air with the aerosol formed by atomizing the aerosol-forming material 33. The mixed air is distributed in the airflow channel 3520 and then evenly flows into each air outlet channel 3526. It may be understood that in other embodiments, the air inlet channel 3525 may alternatively be communicated with the airflow channel 3520. To be specific, the lower air inlet of the air outlet channel 3526 is closer to the aerosol-forming material 33 than the lower air outlet of the air inlet channel 3525. In some other embodiments, the lower air inlet of the air outlet channel 3526 and the lower air outlet of the air inlet channel 3525 may alternatively be located at a same horizontal plane.

[0292] There is a spacing between the lower end surface of the extension portion 3523 and the upper end surface of the heating element 32, to facilitate thermal insulation. In other embodiments, the lower end surface of the extension portion 3523 may alternatively abut against the upper end surface of the heating element 32 or the fixing member 36, so as to press and fix the heating element 32 and the fixing member 36.

[0293] The sealing film 351 may be adhered to an upper side of the sealing plug 352, and covers at least the air inlet channel 3525 and the air outlet channel 3526. During use, the sealing film 351 may be first torn off, to expose the air inlet channel 3525 and the air outlet channel 3526. In other embodiments, the air inlet channel 3525 and the air outlet channel 3526 may be exposed by piercing the sealing film 351.

[0294] During assembly of the aerosol-forming product 30, the heating element 32 may be first loaded into the container 31. Then, the container 31 is filled with the aerosol-forming material 33, and the sealing plug 352 is plugged. Finally, the sealing film 351 is adhered.

[0295] FIG. 16 to FIG. 17 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment also includes a container 31, a heating element 32, an aerosol-forming material 33, a sealing film 351, and a sealing plug 352. For structures of the container 31, the sealing film 351, and the sealing plug 352, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0296] The heating element 32 in this embodiment also includes a heating bottom wall 322 and two heating side walls 321 respectively extending upward from two ends of the heating bottom wall 322. Different from the foregoing embodiment, in this embodiment, at least one protrusion portion 3215 extends out from each heating side wall 321 to an inner wall surface of the container 31. In this embodiment, there are a plurality of protrusion portions 3215. The plurality of protrusion portions 3215 respectively extend from two transverse side edges of the heating side wall 321 to a direction away from the heating bottom wall 322, and may be perpendicular to the heating side wall 321. In other embodiments, the protrusion portion 3215 and the heating side wall 321 may be disposed at an acute angle or an obtuse angle. The heating element 32 may abut against the inner wall surface of the container 31 by using the protrusion portion 3215, so that the heating element 32 can be fixed in the container 31, and a fixing member 36 is not required in the container 31.

[0297] It may be understood that in other embodiments, a fixing member 36 or a limiting member 34 may alternatively be disposed in the container 31, to block the flow of the aerosol-forming material 33 to the sealing plug 352.

[0298] FIG. 18 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment also includes a container 31, a heating element 32, an aerosol-forming material 33, a sealing film 351, and a sealing plug 352.

[0299] Different from the foregoing embodiment, the heating element 32 in this embodiment is cylindrical, and may include a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. The heating element 32 in this embodiment may be used as a container to accommodate the aerosol-forming material 33. A through hole 3220 may be further provided in the heating side wall 321 and / or the heating bottom wall 322, to ensure even enameling of the heating element 32. In some embodiments, the hole diameter of the through hole 3220 may be 0.5 mm to 1.5 mm. Within this range, it is possible to prevent the pasty aerosol-forming material 33 from flowing out of the through hole 3220.

[0300] An outer diameter of the heating side wall 321 may be smaller than or equal to an inner diameter of the container 31. When the outer diameter of the heating side wall 321 is equal to the inner diameter of the container 31, an outer wall surface of the heating side wall 321 is in contact with an inner wall surface of the container 31, so as to directly limit the heating element 32. When the outer diameter of the heating side wall 321 is smaller than the inner diameter of the container 31, the outer wall surface of the heating side wall 321 is not in contact with the inner wall surface of the container 31, which is beneficial to thermal insulation and assembly. At this moment, the heating element 32 may be limited by disposing another limiting structure.

[0301] In addition, this embodiment is further different from the foregoing embodiment in that a plurality of air inlet channels 3525 and at least one air outlet channel 3526 are formed in the sealing plug 352 in this embodiment. The plurality of air inlet channels 3525 are distributed on the outer periphery of the at least one air outlet channel 3526, and a total cross-sectional area of the plurality of air inlet channels 3525 is not smaller than a cross-sectional area of the at least one air outlet channel 3526.

[0302] During assembly of the aerosol-forming product 30, the aerosol-forming material 33 may be first filled in the heating element 32, and then placed in the container 31 together. Then, the sealing plug 352 is plugged. Finally, the sealing film 351 is adhered. Alternatively, the heating element 32 may be first placed in the container 31, and then the heating element 32 is filled with the aerosol-forming material 33. Then, the sealing plug 352 is plugged. Finally, the sealing film 351 is adhered.

[0303] FIG. 19 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference between this embodiment and the foregoing embodiments lies in that an air outlet channel 3526 in this embodiment is formed between an outer wall surface of a sealing plug 352 and an inner wall surface of a container 31, and an air inlet channel 3525 is formed in the sealing plug 352.

[0304] Specifically, there may be a plurality of air outlet channels 3526. The plurality of air outlet channels 3526 may be formed by recessing the outer wall surface of the sealing portion 3522 and may be evenly spaced apart along a peripheral direction of the sealing portion 3522.

[0305] It may be understood that in other embodiments, the air outlet channel 3525 may alternatively be formed between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31, and the air inlet channel 3526 is formed in the sealing plug 352. Alternatively, both the air inlet channel 3525 and the air outlet channel 3526 may be formed between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31.

[0306] FIG. 20 to FIG. 21 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment includes a container 31, an aerosol-forming material 33, a sealing member 38, and a sealing film 351. An accommodating cavity 310 having an opening 311 at one end is formed in the container 31. The aerosol-forming material 33 is disposed in the accommodating cavity 310. The sealing member 38 is disposed at the opening 311, and has a first state in which the opening 311 is sealed and a second state in which the opening 311 is unsealed.

[0307] Specifically, in this embodiment, the container 31 includes a container body 316 and a container cover 317 disposed at one end of the container body 316. The opening 311 is formed on the container cover 317. The container body 316 is cylindrical, and may include a tubular container side wall 312 and a container bottom wall 313 disposed at one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define the accommodating cavity 310 for accommodating the aerosol-forming material 33. An opening 318 is formed by opening the other end of the container side wall 312. The container cover 317 is disposed at the opening 318 to cover the opening 318.

[0308] The container body 316 may be made of a high temperature resistant material, such as glass, ceramics, metal, or plastic. In this embodiment, the container body 316 is made of a ferromagnetic metal material, and can generate heat by induction of a magnetic field in an electromagnetic environment, so as to heat the aerosol-forming material 33.

[0309] The container cover 317 may be made of a high temperature resistant material, such as glass, ceramics, metal, or plastic. The container cover 317 may be embedded in the opening 318. In some embodiments, the container cover317 may be riveted in the opening 318 by using an interference fit. Because the container cover 317 generally does not come into contact with the aerosol-forming material 33, to avoid dry heating, the container cover 317 may be made of a material that does not generate heat in the magnetic field or generates less heat. In this embodiment, the container cover 317 is made of a non-ferromagnetic metal material.

[0310] It may be understood that in other embodiments, when the container body 316 and the container cover 317 are made of a same material, for example, when the container body 316 and the container cover 317 are both made of a non-ferromagnetic material or a ferromagnetic material, the container body 316 and the container cover 317 may alternatively be integrally formed.

[0311] The container cover 317 may include an end cover 3171 having an annular sheet shape, an inner side wall 3172 extending downward from an inner edge of the end cover 3171, and an outer side wall 3173 extending downward from an outer edge of the end cover 3171. The outer side wall 3173 is in sealing fit with the inner wall surface of the container side wall 312. An inner wall surface of the inner side wall 3172 defines the opening 311. An outer diameter of the inner side wall 3172 is smaller than an inner diameter of the outer side wall 3173, so that an annular space 3174 is formed between an outer wall surface of the inner side wall 3172 and an inner wall surface of the outer side wall 3173. This structure is beneficial to reducing materials, reducing costs, and reducing the weight of the aerosol-forming product 30.

[0312] The sealing member 38 is at least partially detachably disposed at the opening 311. The sealing member 38 can seal the opening 311 in a first state, so that the aerosol-forming material 33 in the container 31 cannot flow out of the opening 311, thereby ensuring that the aerosol-forming material 33 in the container 31 does not leak when the aerosol-forming product 30 is disposed upright, inversely disposed, or obliquely disposed. The opening 311 can be unsealed when the sealing member 38 is in a second state, so that the accommodating cavity 310 may be communicated with the outside via the opening 311, to implement air inlet and air outlet to / from the aerosol-forming product 30. In the second state, the sealing member 38 may be completely separated from the opening 311, or partially separated from the opening 311 while being partially connected to the opening 311.

[0313] Further, in the second state, the sealing member 38 is at least partially located in the accommodating cavity 310. In this way, when the aerosol-forming material 33 remains on the sealing member 38 because the aerosol-forming product 30 is inverted or inclined, the aerosol-forming material 33 remaining on the sealing member 38 can be heated in the accommodating cavity 310 for continuous use, thereby reducing or avoiding the waste of the aerosol-forming material 33.

[0314] In this embodiment, the sealing member 38 may be completely detachably disposed at the opening 311, and is configured to be pressed and fall into the accommodating cavity 310 in the first state. In this way, when being required to be heated for use, the sealing member 38 may be poked into the accommodating cavity 310 by pressing, and the aerosol-forming material 33 remaining on the sealing member 38 may fall into the accommodating cavity 310 along with the sealing member 38, so that the aerosol-forming material 33 cannot be wasted.

[0315] In addition, in a state in which the opening 311 is unsealed, the inner side wall 3172 of the container cover 317 extends inward of the accommodating cavity 310 and surrounds around the opening 311, so as to also block the flow of the aerosol-forming material 33 out of the opening 311. Preferably, a bottom surface of the inner side wall 3172 is spaced apart from a top surface of the aerosol-forming material 33. In addition, when the aerosol-forming material 33 is pasty, a liquid level of the aerosol-forming material 33 when being heated and liquefied is lower than the bottom surface of the inner side wall 3172.

[0316] Specifically, the sealing member 38 may include a tubular sealing side wall 381 and a sealing bottom wall 382 disposed at one end of the sealing side wall 381. The sealing side wall 381 is in a shape of a hollow tube, which is beneficial to reducing materials, reducing costs, and reducing the weight of the aerosol-forming product 30. The sealing side wall 381 is configured to be in sealing fit with an inner wall surface of the opening 311 in the first state. The sealing bottom wall 382 can cover the opening 311 and can be pressed by an external force. There is a binding force between the outer wall surface of the sealing side wall 381 and the inner wall surface of the opening 311. When a pressing force on the sealing bottom wall 382 is greater than the binding force, the sealing member 38 may be separated from the opening 311 and fall into the accommodating cavity 310, so as to unseal the opening 311.

[0317] Further, the sealing side wall 381 may be in a shape of a tapered tube. Specifically, the sealing side wall 381 has an inner end (or a lower end) facing the accommodating cavity 310 and an outer end (or an upper end) facing away from the accommodating cavity 310. A cross-sectional area of the sealing side wall 381 is gradually reduced from the inner end to the outer end. Correspondingly, a cross-sectional area of the opening 311 is also gradually reduced in a direction from the inner end to the outer end. The tapered design, on one hand, may prevent the sealing member 38 from falling upward, and on the other hand, may help the sealing member 38 to fall downward away from the opening 311 when being pressed.

[0318] The sealing side wall 381 may be in interference fit with the inner wall surface of the opening 311 by clamping or the like, to ensure that the sealing member 38 is not easily released. In some embodiments, the sealing side wall 381 may include a plurality of clamping arms 3811 spaced apart along a peripheral direction. The sealing member 38 is assembled with the inner wall surface of the opening 311 by using the plurality of clamping arms 3811 through interference fit. In this embodiment, there are three clamping arms 3811 evenly spaced apart along the peripheral direction of the sealing side wall 381, facilitating even stressing. In other embodiments, the quantity of the clamping arms 3811 may alternatively be two or more than three.

[0319] In this embodiment, the sealing bottom wall 382 is disposed at the lower end of the sealing side wall 381, and the upper end of the sealing side wall 381 is open. The upper end of the sealing side wall 381 may be formed with a plurality of slots 3810 spaced apart along the peripheral direction. Each slot 3810 may extend downward from the upper end surface of the sealing side wall 381 but does not extend through the lower end surface of the sealing side wall 381. The plurality of slots 3810 divide an upper half of the sealing side wall 381 into clamping arms 3811 and body portions 3812 that are alternately distributed in the peripheral direction. The length of the clamping arms 3811 in the peripheral direction may be smaller than the length of the body portions 3812 in the peripheral direction. By means of the slots 3810, the clamping arms 3811 can expand outward, so as to be in interference fit with the inner wall surface of the opening 311. A lower half of the sealing side wall 381 is closed in the peripheral direction, and no slot structure is formed thereon, so as to prevent the aerosol-forming material 33 from seeping to the outside through the slots 3810.

[0320] It may be understood that in other embodiments, the sealing member 38 is not limited to the foregoing structural form. For example, the sealing bottom wall 382 may be disposed at the upper end of the sealing side wall 381. For another example, the sealing member 38 may be a solid structure. For another example, the sealing side wall 381 may be formed with a protrusion structure protruding outward, and is in interference fit with the inner wall surface of the opening 311 through the protrusion structure.

[0321] The sealing member 38 may be made of a high temperature resistant material, such as metal or plastic. In this embodiment, the sealing member 38 is made of a non-ferromagnetic metal material. It may be understood that because the sealing member 38 can be in contact with the aerosol-forming material 33 after falling into the accommodating cavity 310, in other embodiments, the sealing member 38 may alternatively be made of a ferromagnetic metal material. At this moment, the container body 316 may be made of a ferromagnetic material or a non-ferromagnetic material. In some other embodiments, the sealing member 38 and the container body 316 may both be made of a non-ferromagnetic material, and a heating element may be additionally disposed outside or inside the container body 316 to perform electromagnetic induction heating.

[0322] The sealing film 351 covers at least the sealing member 38, to ensure cleanness of the sealing member 38, and further prevent the sealing member 38 from being incorrectly pressed into the container 31 before use. The sealing film 351 may be a tearable sealing film and is adhered to the upper end surface of the container 31. During use, the sealing film 351 may be first torn off to expose the sealing member 38. In other embodiments, the sealing film 351 may alternatively be pierced to expose the sealing member 38.

[0323] During assembly of the aerosol-forming product 30, the aerosol-forming material 33 may be first filled in the container body 316, and the sealing member 38 is assembled onto the container cover 317. Then the container cover 317 with the sealing member 38 is riveted to the container body 316. Finally, the sealing film 351 is adhered. During use, the sealing film 351 is first torn off, and then the sealing member 38 is poked downward into the container body 316 for normal use. The aerosol-forming material 33 is disposed inside the container body 316, and does not easily flow out of the opening 311 after being heated and liquefied.

[0324] In a process of assembling the suction nozzle 10, the main unit 20, and the aerosol-forming product 30, the sealing member 38 may be poked downward through the air guide tube 13 in the suction nozzle 10, to implement air inlet and air outlet to / from the aerosol-forming product 30. At this moment, the outer diameter of the air guide tube 13 is smaller than the inner diameter of the opening 311, so that a vent clearance for airflow circulation is formed between the outer wall surface of the air guide tube 13 and the inner wall surface of the opening 311. One of the vent clearance and the air guide channel 130 may be used for air inlet, and the other may be used for air outlet. It may be understood that in other embodiments, the sealing member 38 may alternatively not be poked out by using the air guide tube 13. At this moment, the air guide tube 13 may not extend into the opening 311.

[0325] FIG. 22 to FIG. 23 show an aerosol-forming product 30 according to some embodiments of the present disclosure. In this embodiment, the container 31 includes only a container body 316. An upper end of the container body 316 is opened to form an opening 311. The container body 316 may be made of a ferromagnetic material, and can generate heat by induction of a magnetic field. The sealing member 38 may be switched from a first state in which the opening 311 is sealed to a second state in which the opening 311 is unsealed in a deformation mode, for example, a mode of heated deformation.

[0326] In some implementations, the sealing member 38 may be made of a hot melt material, and may be in a sheet shape or another shape. The sealing member 38 can fall into the container 31 after being heated and hot-melted.

[0327] In some implementations, the sealing member 38 may be made of a shape memory material. The sealing member 38 can change its shape after being heated, so as to be disconnected from the opening 311. The shapes of the sealing member 38 in the first state and the second state are not limited, as long as the opening 311 can be sealed in the first state and the opening 311 can be unsealed in the second state.

[0328] In some implementations, the sealing member 38 may include a sealing body and a hot melt adhesive connecting a peripheral edge of the sealing body to a peripheral edge of the opening 311 in a sealing mode. A material of the sealing body may be not limited. The hot melt adhesive is melted after being heated, so that the sealing body is separated from the opening 311 and falls into the container 31.

[0329] FIG. 24 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that when in the second state, the sealing member 38 in this embodiment is partially connected to the opening 311 and partially located in the accommodating cavity 310.

[0330] A mode of switching the sealing member 38 from the first state to the second state may include a deformation mode or a rotation connection mode. For example, the sealing member 38 may be made of a shape memory material, and can change its shape and switch to the second state after being heated. For another example, the sealing member 38 is rotatably connected to the opening 311, and can rotatably unseal the opening 311 by pressing or the like.

[0331] FIG. 25 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-forming material 33, and a sealing film 351. An accommodating cavity 310 having an opening 311 at one end is formed in the container 31. The aerosol-forming material 33 is disposed in the accommodating cavity 310 and may be communicated with the outside via the opening 311. Further, the container 31 includes a blocking portion 315 extending from at least a part of a peripheral edge of the opening 311 into the accommodating cavity 310 and / or away from the accommodating cavity 310. The blocking portion 315 can be configured to block the flow of the aerosol-forming material 33 out of the opening 311 when the aerosol-forming product 30 is inclined or inverted. The heating element 32 is disposed in the accommodating cavity 310 and is at least partially in contact with the aerosol-forming material 33. The heating element 32 can generate heat by induction of a magnetic field in an electromagnetic environment, and transfer the heat to the aerosol-forming material 33, so as to heat the aerosol-forming material 33.

[0332] In this embodiment, the container 31 may include a tubular container side wall 312, a container bottom wall 313 disposed at a lower end of the container side wall 312, a container top wall 314 disposed at an upper end of the container side wall 312, and a blocking portion 315 extending from the container top wall 314 into the accommodating cavity 310. The container top wall 314 has an annular plate shape, and an inner wall surface thereof defines the opening 311. A center line of the opening 311 may be parallel to or coincide with a center line of the accommodating cavity 310. The blocking portion 315 extends by a length from a peripheral edge of the opening 311 into the accommodating cavity 310. An inner wall surface of the blocking portion 315 defines a communication hole 3150 communicated with the opening 311.

[0333] In some embodiments, the outer diameter of the aerosol-forming product 30 may be 10 mm to 12 mm, and the height may be 10 mm to 12 mm. The minimum cross-sectional area of the communication hole 3150 may be 2 mm2 to 3.5 mm2, or the minimum hole diameter of the communication hole 3150 may be 1.5 mm to 2.1 mm. The height H of the blocking portion 315 may be 1.5 mm to 3 mm, or the height H of the blocking portion 315 may be ⅛ to 3 / 10 of the height of the aerosol-forming product 30. Within this range, it may be ensured that the blocking portion 315 can well block leakage of the aerosol-forming material 33.

[0334] In this embodiment, the container top wall 314 is of a concentric annulus and a center line thereof coincides with the center line of the accommodating cavity 310. The blocking portion 315 is of a circular tube and extends vertically downward from an inner wall surface of the container top wall 314. The blocking portion 315 is perpendicular to the container top wall 314, and an inner diameter and an outer diameter of the blocking portion 315 both remain unchanged in an axial direction thereof. An outer diameter of the blocking portion 315 is smaller than an inner diameter of the accommodating cavity 310, so that an outer wall surface of the blocking portion 315 is spaced apart from the inner wall surface of the container side wall 312. In addition, in this embodiment, the container 31 has an even wall thickness structure. To be specific, the container side wall 312, the container bottom wall 313, the container top wall 314, and the blocking portion 315 that constitute the container 31 have a same or approximately a same thickness. In some embodiments, the wall thickness of the container 31 may be 0.1 mm to 0.5 mm. In other embodiments, the container 31 may alternatively have an uneven wall thickness structure.

[0335] It may be understood that in other embodiments, the blocking portion 315 may have another structural shape. For example, there may be an obtuse angle or an acute angle between the blocking portion 315 and the container top wall 314. For another example, the blocking portion 315 may have another shape such as an elliptic tube or a square tube having a cross-sectional area keeping unchanged from bottom to top, or may have a tapered tube having a cross-sectional area gradually increased or reduced from bottom to top. For another example, the blocking portion 315 may alternatively have a non-closed tubular structure. Specifically, the blocking portion 315 may be formed with one or more notches extending axially.

[0336] A bottom surface of the blocking portion 315 (i.e. a surface of the blocking portion 315 close to the container bottom wall 313) and a top surface of the aerosol-forming material 33 (i.e. a surface of the aerosol-forming material 33 away from the container bottom wall 313) are spaced apart. When the aerosol-forming material 33 is pasty, a liquid level of the aerosol-forming material 33 when being heated and liquefied is lower than the bottom surface of the blocking portion 315. By means of the foregoing design, regardless of the state in which the aerosol-forming product 30 is placed upright, placed obliquely, or placed inversely, it is not easy for the aerosol-forming material 33 to leak out of the opening 311, and it is not easy for the aerosol-forming material 33 to flow out of the opening 311 after being heated and liquefied.

[0337] For the structure of the heating element 32, refer to the foregoing embodiments. Specifically, in this embodiment, the heating element 32 is cylindrical. The cylindrical heating element 32 may further be used as a container to accommodate the aerosol-forming material 33. The aerosol-forming material 33 may be loaded into the heating element 32 through the opening 311 via an upper opening of the heating element 32. An outer diameter of the heating element 32 may be smaller than or equal to an inner diameter of the container side wall 312. It may be understood that in other embodiments, the aerosol-forming product 30 may alternatively not be provided with the heating element 32.

[0338] Further, in some embodiments, the aerosol-forming product 30 may further include a sealing film 351 detachably adhered to the container 31. When being required to be heated for use, the sealing film 351 may be first torn off, to expose the opening 311, and then the aerosol-forming product 30 is assembled to the main unit 20.

[0339] The container 31 may be of an integral forming structure, and may be made of a high temperature resistant material, such as glass, ceramics, metal, or plastic. In this embodiment, the container 31 is a glass tube formed by sintering. During manufacture of the aerosol-forming product 30, the heating element 32 may be placed inside a body of the container 31, and then be formed by sintering, so that the heating element 32 and the container 31 form an integral structure by sintering. Then, the aerosol-forming material 33 is loaded into the container 31 through the opening 311. Finally, the sealing film 351 is adhered. Because the heating element 32 may be placed in the container 31 before the container 31 is formed by sintering, the size of a cross-sectional outer contour (for example, the diameter, length, or width of the cross-sectional outer contour) of the heating element 32 may be greater than, smaller than, or equal to the size of a cross-sectional outer contour of the opening 311 (for example, the diameter, length, or width of the cross-sectional outer contour). The size of the heating element 32 may be flexibly designed according to requirements.

[0340] It may be understood that in other embodiments, the container 31 may have a separate structure. For example, the container top wall 314 and the container side wall 312 are separately disposed, and / or the blocking portion 315 and the container top wall 314 are separately disposed.

[0341] FIG. 26 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 is also cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, and a sealing film 351. For the structures of the heating element 32 and the sealing film 351, refer to related descriptions in the foregoing embodiments. Details are not described herein again.

[0342] Different from the foregoing embodiments, an upper end of the container 31 in this embodiment is not provided with a container top wall, and an upper end of the container side wall 312 is opened to form an opening 311. Specifically, in this embodiment, the container 31 includes a tubular container side wall 312, a container bottom wall 313 disposed at a lower end of the container side wall 312, and a blocking portion 315 extending from an upper peripheral edge of the container side wall 312 into the accommodating cavity 310.

[0343] The blocking portion 315 further has a tendency to contract toward the center of the opening 311, so that the minimum cross-sectional area of a cross-sectional inner contour of the blocking portion 315 is smaller than the cross-sectional area of the opening 311. In this embodiment, a tube wall of the blocking portion 315 has an arc shape, and both an outer diameter and an inner diameter of the blocking portion 315 are gradually reduced and contracted in an arc from an end close to the opening 311 to an end away from the opening 311.

[0344] FIG. 27 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment includes a contracted section 3151 extending from an upper peripheral edge of the container side wall 312 into the accommodating cavity 310 and an extension section 3152 extending from an end of the contracted section 3151 away from the opening 311. The contracted section 3151 has a frustum cone shape, and both an outer diameter and an inner diameter of the contracted section 3151 are gradually reduced and contracted in a straight from an end close to the opening 311 to an end away from the opening 311. The extension section 3152 is in a shape of a horizontally disposed annular plate, and extends inward radially by a distance from an end of the contracted section 3151 away from the opening 311. In other embodiments, the extension section 3152 may alternatively be disposed obliquely or vertically.

[0345] FIG. 28 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the container 31 in this embodiment has a separate structure, and includes a container body 316 and a container cover 317 disposed at an upper end of the container body 316.

[0346] The container body 316 has a cylindrical shape with an open upper end, and includes a container bottom wall 313 and a tubular container side wall 312 extending upward from a peripheral edge of the container bottom wall 313. The container cover 317 may include a container top wall 314 covering an upper end of the container side wall 312 and a blocking portion 315 extending downward from an inner peripheral edge of the container top wall 314.

[0347] In addition, the blocking portion 315 may further include a first blocking section 3153 and a second blocking section 3154 extending from a lower end of the first blocking section 3153. An angle (including a right angle, an acute angle, and an obtuse angle) is formed between the first blocking section 3153 and the second blocking section 3154. Specifically, in this embodiment, the first blocking section 3153 is vertically disposed, and an inner diameter and an outer diameter of the first blocking section 3153 remain unchanged in an axial direction thereof. The second blocking section 3154 is disposed at an angle with a vertical direction, and an inner diameter and an outer diameter of the second blocking section 3154 are gradually reduced in a direction away from the opening 311 in an axial direction thereof. In other embodiments, the blocking portion 315 may alternatively have a one-section structure, or may include three or more blocking sections.

[0348] The container body 316 and the container cover 317 may be made of different materials, or may be made of a same material. In one embodiment, the container body 316 is made of a ferromagnetic metal material, and can generate heat by induction of a magnetic field in the magnetic field, so as to heat the aerosol-forming material 33 accommodated in the container body 316. The container cover 317 is made of a non-ferromagnetic metal material, so as to avoid dry heating. In this case, the container 31 does not need to be additionally provided with a heating element.

[0349] In another embodiment, the container body 316 and the container cover 317 are both made of a non-ferromagnetic material, and a heating element is disposed in the container 31 to generate heat.

[0350] FIG. 29 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment extends from a peripheral edge of the opening 311 in a direction away from the accommodating cavity 310.

[0351] Similar to the foregoing embodiments, in this embodiment, the blocking portion 315 also has a tendency to contract toward the center of the opening 311, so that the minimum cross-sectional area of a cross-sectional inner contour of the blocking portion 315 is smaller than the cross-sectional area of the opening 311. Specifically, in this embodiment, the blocking portion 315 has a tapered tube shape disposed coaxially with the opening 311 and the accommodating cavity 310, and a cross-sectional area of the blocking portion 315 is gradually reduced in a direction away from the opening 311.

[0352] FIG. 30 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment extends from a partial edge of the opening 311 in a direction away from the accommodating cavity 310.

[0353] Specifically, the blocking portion 315 may extend obliquely upward from an edge of one side of the opening 311 to the other side. Further, a projection of the blocking portion 315 on the opening 311 along a vertical direction (or along an axial direction of the container 31) can block at least a large part of the opening 311, thereby providing a better leakage preventing effect.

[0354] FIG. 31 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment includes an inner blocking portion 3155 extending from a partial peripheral edge of the opening 311 to the accommodating cavity 310 and an outer blocking portion 3156 extending from a partial peripheral edge of the opening 311 to a direction away from the accommodating cavity 310.

[0355] The inner blocking portion 3155 and the outer blocking portion 3156 may respectively extend from edges of two opposite sides of the opening 311. Further, a projection of the inner blocking portion 3155 on the opening 311 along the vertical direction partially overlaps a projection of the outer blocking portion 3156 on the opening 311 along the vertical direction, so that a leakage preventing effect is better.

[0356] As shown in FIG. 32 and FIG. 33, an aerosol-forming product 30 in some embodiments of the present disclosure includes a container 31 and a heating element 32 disposed in the container 31. The container 31 may have a cylindrical shape with an open upper end, and may include a tubular container side wall 312 and a container bottom wall 313 covering a lower end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define an accommodating cavity 310 with an open upper end. In other embodiments, the container 31 is not limited to being cylindrical, and may alternatively be of another cylindrical shape such as an elliptic cylinder or a square cylinder, or may be of a tube with two open ends.

[0357] The shape of the heating element 32 is not limited. For example, the heating element may have various shapes such as a sheet shape, a tube shape, a barrel shape, and a helical shape. Specifically, in this embodiment, the heating element 32 has a cylindrical shape with an open upper end, and may include a tubular heating side wall 321 and a heating bottom wall 322 disposed at a lower end of the heating side wall 321. The heating bottom wall 322 may abut against the container bottom wall 313 of the container 31.

[0358] At least two outer positioning portions 3124 may protrude outward from an outer wall surface of the container side wall 312. The at least two outer positioning portions 3124 are spaced apart in a peripheral direction of the container side wall 312. When the container 31 is loaded into the cavity 240 of the main unit 20, the at least two outer positioning portions 3124 are attached to a cavity wall surface of the cavity 240, so that the container 31 can be centrally positioned in the cavity 240. The container side wall 312 is in clearance fit with the cavity wall surface of the cavity 240, so as to facilitate insertion and pull out of the container 31, and further help to reduce heat transferred by the container 31 to the main unit 20. In other embodiments, at least two positioning portions may protrude inward from the cavity wall surface of the cavity 240, so that a part of an outer wall surface of the container side wall 312 abuts against the at least two positioning portions, thereby positioning the container 31 in the cavity 240.

[0359] Preferably, there are at least three outer positioning portions 3124. The at least three outer positioning portions 3124 are evenly spaced apart in the peripheral direction of the container side wall 312. Each outer positioning portion 3124 may extend downward from a top end to a bottom end of the container side wall 312 along a straight line. To be specific, an extension direction of each outer positioning portion 3124 is parallel to an axial direction of the container side wall 312, to facilitate processing and forming. In other embodiments, the outer positioning portion 3124 may alternatively have another structural form. For example, the outer positioning portion may alternatively extend obliquely downward from the top of the container side wall 312 along a straight line (to be specific, an angle is formed with the axial direction of the container side wall 312), or may alternatively extend along a non-straight line. In addition, in some other embodiments, each outer positioning portion 3124 may alternatively not be formed on the entire axial length of the container side wall 312, for example, may extend upward from the bottom end of the container side wall 312 by a distance but does not reach the top end of the container side wall 312.

[0360] Further, an outer surface (i.e. a surface away from the central axis of the container 31) of the outer positioning portion 3124 is an arc surface or is at least partially an arc surface. The outer surface of the outer positioning portion 3124 abuts against the cavity wall surface of the cavity 240 via the arc surface, so as to reduce or avoid damage caused by scraping the cavity wall surface of the cavity 240 during insertion and pull out of the container 31.

[0361] Each outer positioning portion 3124 may include a solid structure, or may include a hollow structure. Specifically, in this embodiment, each outer positioning portion 3124 has a solid structure with an approximately semi-circular cross section. In other embodiments, each outer positioning portion 3124 may alternatively be a hollow structure with an approximately semi-annular cross section.

[0362] At least two inner positioning portions 3125 may protrude inward from an inner wall surface of the container side wall 312. The at least two inner positioning portions 3125 are spaced apart in a peripheral direction of the container side wall 312. An outer wall surface (i.e. a surface away from the central axis of the heating element 32) of the heating side wall 321 of the heating element 32 may abut against the at least two inner positioning portions 3125, to centrally position the heating element 32 in the container 31, thereby ensuring temperature uniformity of the heating element 32 and consistency of a heating effect. However, the outer wall surface of the heating side wall 321 is in clearance fit with an inner wall surface of the container side wall 312, so as to form a clearance 3210. On one hand, the heating element 32 can be more easily assembled into the container 31 or removed from the container 31. On the other hand, thermal isolation between the heating element 32 and the container 31 is facilitated, thereby reducing heat transferred by the heating side wall 321 to the container side wall 312.

[0363] Preferably, there are at least three inner positioning portions 3125. The at least three inner positioning portions 3125 are evenly spaced apart in the peripheral direction of the container side wall 312. Each inner positioning portion 3125 may extend downward from a top end to a bottom end of the container side wall 312 along a straight line. To be specific, an extension direction of each inner positioning portion 3125 is parallel to an axial direction of the container side wall 312, to facilitate processing and forming. In other embodiments, the inner positioning portion 3125 may alternatively have another structural form. For example, the outer positioning portion may alternatively extend obliquely downward from the top of the container side wall 312 along a straight line (to be specific, an angle is formed with the axial direction of the container side wall 312), or may alternatively extend along a non-straight line. In addition, in some other embodiments, each inner positioning portion 3125 may alternatively not be formed on the entire axial length of the container side wall 312, for example, may extend upward from the bottom end of the container side wall 312 by a distance but does not reach the top end of the container side wall 312.

[0364] Further, an inner surface (i.e. a surface close to the central axis of the container 31) of the inner positioning portion 3125 is an arc surface or is at least partially an arc surface. An outer surface of the inner positioning portion 3125 abuts against the heating side wall 321 via the arc surface, so as to reduce or avoid scraping damage caused during insertion and pull out of the heating element 32.

[0365] Each inner positioning portion 3125 may include a solid structure, or may include a hollow structure. Specifically, in this embodiment, each inner positioning portion 3125 has a solid structure with an approximately semi-circular cross section. In other embodiments, each inner positioning portion 3125 may alternatively be a hollow structure with an approximately semi-annular cross section.

[0366] The quantity of the inner positioning portions 3125 and the quantity of the outer positioning portions 3124 may be equal or not equal. In addition, the plurality of inner positioning portions 3125 and the plurality of outer positioning portions 3124 may completely overlap or be completely staggered in the peripheral direction of the container side wall 312, or may partially overlap and be partially staggered. In this embodiment, there may be three inner positioning portions 3125 and three outer positioning portions 3124. The three inner positioning portions 3125 and the three outer positioning portions 3124 completely overlap in the peripheral direction of the container side wall 312. More specifically, each inner positioning portion 3125 is combined with the corresponding outer positioning portion 3124 to form a cylindrical solid convex column.

[0367] FIG. 34 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, there may be three inner positioning portions 3125 and three outer positioning portions 3124. The three inner positioning portions 3125 and the three outer positioning portions 3124 completely overlap in the peripheral direction of the container side wall 312. Each inner positioning portion 3125 and each outer positioning portion 3124 both have a semi-annular cross section. Each inner positioning portion 3125 and the corresponding outer positioning portion 3124 are combined to form an annular hollow convex column.

[0368] FIG. 35 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, there may be three inner positioning portions 3125 and three outer positioning portions 3124. The three inner positioning portions 3125 and the three outer positioning portions 3124 are completely staggered in the peripheral direction of the container side wall 312.

[0369] FIG. 36 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, the container side wall 312 of the container 31 is provided with only an inner positioning portion 3125 but is not provided with an outer positioning portion 3124. In other embodiments, the container side wall 312 of the container 31 may alternatively be provided with only an outer positioning portion 3124 but is not provided with an inner positioning portion 3125.

[0370] FIG. 37 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, there are two inner positioning portions 3125, and the two inner positioning portions 3125 are respectively located on two radially opposite sides of the container side wall 312. There are also two outer positioning portions 3124, and the two outer positioning portions 3124 are respectively located on two radially opposite sides of the container side wall 312. The two inner positioning portions 3125 and the two outer positioning portions 3124 may overlap or may be staggered in the peripheral direction of the container side wall 312.

[0371] In other embodiments, the shapes and quantities of the inner positioning portion 3125 and the outer positioning portion 3124 are not limited, provided that the heating element 32 can be positioned in the container 31 and the container 31 can be fixed in the cavity 240. For example, there may be only one inner positioning portion 3125, which may have a convex ring shape. Similarly, there may be only one outer positioning portion 3124, which may have a convex ring shape. For another example, the inner positioning portion 3125 and / or the outer positioning portion 3124 may alternatively be distributed in a convex point shape. The positioning portion may alternatively be formed by protruding from the heating element 32, or may be formed by protruding from the cavity wall surface of the cavity 240.

[0372] As shown in FIG. 38 to FIG. 40, an aerosol-forming system 100 according to a twenty-fifth embodiment of the present disclosure includes a housing 21, an aerosol-forming product 30, a heating control assembly 27, and a suction nozzle 10. The heating control assembly 27 is disposed in the housing 21. One end of the housing 21 is provided with a cavity for accommodating the aerosol-forming product 30. The aerosol-forming product 30 is replaceably disposed in the cavity. An aerosol-forming material 33 for forming an aerosol is stored in the aerosol-forming product 30. The suction nozzle 10 is detachably adapted to the aerosol-forming product 30 and is communicated with the aerosol-forming product 30. After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the entire aerosol-forming product 30 may be pulled out from the housing 21 and separated from the suction nozzle 10 to replace a new aerosol-forming product 30. The heating control assembly 27 may heat the aerosol-forming material 33 in the aerosol-forming product 30 to form an aerosol, and the aerosol may flow out through the suction nozzle 10 for a user to take.

[0373] With reference to FIG. 41 to FIG. 43, the aerosol-forming product 30 includes a container 31, a sealing cover 353, and a central tube 354. The container 31 has a cylindrical structure and has an accommodating cavity 310 with an open end. The sealing cover 353 is mounted at the open end of the container 31, and a first vent channel 3533 and a second vent channel 3534 respectively communicating the accommodating cavity 310 with the outside atmosphere are provided in the sealing cover 353. An outer diameter of the central tube 354 is smaller than an inner diameter of the container 31 and is disposed in the accommodating cavity 310. One axial end of the central tube 354 is adapted to the sealing cover 353 and is communicated with the first vent channel 3533. The other axial end of the central tube 354 extends toward a tube bottom of the container 31 to be spaced apart from the tube bottom. A clearance between the central tube 354 and the container 31 is communicated with the second vent channel 3534.

[0374] One of the first vent channel 3533 and the second vent channel 3534 may be used as an air inlet channel, and the other vent channel may be used as an air outlet channel. In some embodiments, outside air may enter the accommodating cavity 310 through the second vent channel 3534 in sequence, and then flow out through the central tube 354 and the first vent channel 3533 by carrying an aerosol formed by atomizing the aerosol-forming material 33. In some other embodiments, outside air may enter the accommodating cavity 310 through the first vent channel 3533 and the central tube 354 in sequence, and then flow out through the second vent channel 3534 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0375] In some other embodiments, the sealing cover 353 may alternatively be provided with only an air inlet channel or an air outlet channel. In some other embodiments, the first vent channel 3533 and / or the second vent channel 3534 may alternatively be formed between the sealing cover 353 and the container 31.

[0376] Specifically, the sealing cover 353 has a cylindrical structure with an open end, and includes a sealing top wall 3531 and a sealing side wall 3532. The sealing side wall 3532 extends from an edge of the sealing top wall 3531 to a same direction and surrounds the sealing top wall 3531 along a peripheral direction. An end of the sealing side wall 3532 away from the sealing top wall 3531 is clamped with the container 31. Therefore, the sealing cover 353 and the container 31 form a non-detachable whole. The first vent channel 3533 and the second vent channel 3534 are both provided in the sealing top wall 3531, so as to be butted with the suction nozzle 10. As a preferred implementation, an edge of an open end of the container 31 is folded outward to form an annular clamping portion 3123, and a clamping slot is provided in a side wall of the sealing cover 353 to clamp the clamping portion 3123.

[0377] It may be understood that an adaptation mode between the sealing cover 353 and the container 31 is not limited thereto, and a non-detachable connection mode, such as screwing buckle connection or soldering may alternatively be used for assembly, thereby avoiding introduction of impurities due to that a user disassembles the aerosol-forming product 30 and voluntarily adds the aerosol-forming material 33, and ensuring the quality of the aerosol-forming material 33. It should be noted that, non-detachable means that disassembly is not implemented without being damaged, mainly to prevent the aerosol-forming product 30 from being secondarily added with the aerosol-forming material 33, and to achieve forced entire replacement.

[0378] The aerosol-forming product 30 further includes an annular sealing ring 355. The sealing ring 355 is disposed at a joint between the sealing top wall 3531 and the open end of the container 31, and communication holes correspondingly communicated with the first vent channel 3533 and the second vent channel 3534 are formed. In this way, the sealing ring 355 may seal a clearance between the sealing cover 353 and the container 31, so as to effectively prevent airflow in the accommodating cavity 310 from leaking from the clearance between the sealing cover 353 and the container 31, and keep airflow in the first vent channel 3533 and the second vent channel 3534 smooth.

[0379] It may be understood that a sealing mode between the container 31 and the sealing cover 353 is not limited. In some other embodiments, sealing may be performed by using an end surface interference fit and a radial interference fit.

[0380] Specifically, in an embodiment, one first vent channel 3533 and three second vent channels 3534 are provided in the sealing top wall 3531 of the sealing cover 353. The first vent channel 3533 is located at a center position of the sealing top wall 3531, and the three second vent channels 3534 surround the first vent channel 3533 along a peripheral direction. It may be understood that the quantities and the position relationship of the first vent channel 3533 and the second vent channel 3534 are not limited, and may be set according to requirements to satisfy different atomization requirements.

[0381] The central tube 354 has a hollow tubular structure with two open ends. The central tube 354 is formed of a high temperature resistant material such as metal or high temperature resistant plastic (for example, polyetheretherketone (PEEK)), thereby preventing from being fused at a high temperature during an atomization process. In an embodiment, the first vent channel 3533 is located at a center position of the sealing top wall 3531. Therefore, the central tube 354 connected to the first vent channel 3533 is disposed coaxially with the container 31. A gap between the central tube 354 and a side wall of the container 31 surrounds the central tube 354 along a peripheral direction.

[0382] It may be understood that the length of insertion of the central tube 354 into the accommodating cavity 310 is not limited, and may be set according to requirements, so that airflow may flow out by fully carrying an aerosol formed by the aerosol-forming material 33 at the bottom of the accommodating cavity 310.

[0383] In some embodiments, the aerosol-forming product 30 further includes a heating element. The heating element is accommodated in the accommodating cavity 310. The housing 21 is provided with a component capable of generating a magnetic field. The heating element may be configured to be heated by induction in the magnetic field, to atomize the aerosol-forming material 33.

[0384] It may be understood that in some other embodiments, the aerosol-forming product 30 may alternatively not be provided with the heating element, but the aerosol-forming material 33 may be heated by infrared radiation, microwaves, or plasma.

[0385] The suction nozzle 10 is adapted to the sealing cover 353 of the aerosol-forming product 30. Corresponding to the structure of the aerosol-forming product 30, the suction nozzle 10 has a first airway and a second airway spaced apart. When the aerosol-forming product 30 is adapted to the housing 21, an end of the aerosol-forming product 30 not provided with the sealing cover 353 is inserted in the cavity, and an end of the aerosol-forming product 30 provided with the sealing cover 353 extends out of the cavity to be butted with the suction nozzle 10. The first airway of the suction nozzle 10 communicates the first vent channel 3533 with the outside atmosphere, and the second airway communicates the second vent channel 3534 with the outside atmosphere.

[0386] Specifically, in some embodiments, to match positions of the first vent channel 3533 and the second vent channel 3534, the first airway of the suction nozzle 10 extends through the suction nozzle 10 in an axial direction, a central axis of the first airway and a central axis of the suction nozzle 10 overlap, and the second airway surrounds the first airway along a peripheral direction.

[0387] In this way, when a user inhales, under a negative pressure, airflow in an external environment flows from the second airway into the suction nozzle 10, and then reaches the bottom of the accommodating cavity 310 through the second vent channel 3534. Afterwards, the airflow flows out of the suction nozzle 10 through the central tube 354, the first vent channel 3533, and the first airway by carrying an aerosol formed by atomizing the aerosol-forming material 33, for the user to take.

[0388] Referring to FIG. 40, in a twenty-fifth embodiment, the first airway of the suction nozzle 10 includes an exhaust channel 112 and a communication channel 111 communicated with each other. The second airway includes a central airway 122 and a lateral airway 121 communicated with each other. An air inlet end of the lateral airway 121 is provided in a side wall of the suction nozzle 10. One end of the central airway 122 is communicated with the first vent channel 3533. The exhaust channel 112 is disposed at an end of the suction nozzle 10 communicated with the atmosphere. The communication channel 111 is spaced apart on the outer periphery of the central airway 122. One end of the communication channel 111 is communicated with the second vent channel 3534, and the other end of the communication channel 111 is communicated with the exhaust channel 112.

[0389] In this way, air in the external environment sequentially flows into the accommodating cavity 310 through the lateral airway 121, the central airway 122, the first vent channel 3533, and the central tube 354, and then flows out of the suction nozzle 10 in sequence through the communication channel 111, the second vent channel 3534, and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0390] As shown in FIG. 44, in some embodiments, the first airway of the suction nozzle 10 includes an exhaust channel 112 and a central airway 122 that are communicated with each other and are coaxially disposed. One end of the exhaust channel 112 is communicated with the outside atmosphere, and the other end of the exhaust channel 112 is connected to one end of the central airway 122. The other end of the central airway 122 is connected to the first vent channel 3533. The second airway includes a communication channel 111. The communication channel 111 is spaced apart on the outer periphery of the central airway 122. An air inlet end of the communication channel 111 is provided in a side wall of the suction nozzle 10. An air outlet end of the communication channel 111 is communicated with the second vent channel 3534.

[0391] In this way, air in the external environment enters the suction nozzle 10 from the communication channel 111, reaches the bottom of the accommodating cavity 310 through the second vent channel 3534, and then flows out of the suction nozzle 10 in sequence through the central tube 354, the first vent channel 3533, the central airway 122, and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0392] Further, in some embodiments, the suction nozzle 10 is further provided with a flow blocking baffle 17. The flow blocking baffle 17 is disposed on an inner wall of the exhaust channel 112 or the central airway 122 to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0393] Specifically, in an embodiment, the flow blocking baffle 17 includes a flow blocking top wall and a flow blocking side wall extending from the flow blocking top wall in a same direction. An end of the flow blocking side wall away from the flow blocking top wall is inserted at an outlet end of the central airway 122. The flow blocking top wall shields the outlet end of the central airway 122, and a lateral air outlet communicating the central airway 122 with the exhaust channel 112 is provided in the flow blocking side wall.

[0394] In this way, aerosol particles with a large diameter in the central airway 122 are adhered to the inner side of the outlet end of the central airway 122 or the flow blocking baffle 17 by collision, and will not enter the oral cavity of a user to affect the inhaling feeling. In addition, the flow blocking baffle 17 may shield the outlet end of the central airway 122, to prevent the user from adding the aerosol-forming material 33 through the central airway 122.

[0395] Optionally, in some embodiments, a vent hole communicated with the communication channel 111 may be further provided in an airway wall of the central airway 122. In this way, air in the external environment enters the suction nozzle 10 from the communication channel 111, reaches the bottom of the accommodating cavity 310 through the second vent channel 3534, and then flows out of the suction nozzle 10 in sequence through the central tube 354, the first vent channel 3533, the central airway 122, and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, a part of the airflow flowing into the communication channel 111 may partially flow into the central airway 122 through the vent hole, and may be mixed with an aerosol in the central airway 122 to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing out of the suction nozzle 10 is adjusted.

[0396] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, and an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0397] As shown in FIG. 45, an aerosol-forming system 100 according to some embodiments of the present disclosure includes a housing 21, an aerosol-forming product 30, a heating control assembly 27, and a suction nozzle 10. The heating control assembly 27 is disposed in the housing 21. One end of the housing 21 is provided with a cavity for accommodating the aerosol-forming product 30. The aerosol-forming product 30 is replaceably disposed in the cavity. The suction nozzle 10 is detachably mounted to the housing 21 and is sleeved outside the aerosol-forming product 30. The aerosol-forming product 30 may be communicated with the outside atmosphere through the suction nozzle 10. The aerosol-forming material 33 is stored in the aerosol-forming product 30. The heating control assembly 27 is configured to supply heat to the cavity, so as to heat the aerosol-forming material 33 in the aerosol-forming product 30 to form an aerosol for a user to take.

[0398] Referring to FIG. 46 to FIG. 48, the aerosol-forming product 30 includes a container 31, a holder 37, and an airway framework 380. The container 31 has an accommodating cavity 310, with an open end, for accommodating the aerosol-forming material 33. An axial end of the holder 37 is adapted to the open end of the container 31. An axial end of the airway framework 380 is adapted to the other axial end of the holder 37. The other axial end of the airway framework 380 is adapted to the suction nozzle 10. The airway framework 380 includes a first airway and a second airway spaced apart. The first airway is communicated with the accommodating cavity 310 and the suction nozzle 10. The second airway is communicated with the accommodating cavity 310 and the outside atmosphere. The two airways are separately spaced apart, and are communicated with each other through the accommodating cavity 310 in the aerosol-forming product 30.

[0399] In this way, the container 31 and the airway framework 380 are connected to each other through the holder 37. Air in the external environment may flow into the accommodating cavity 310 through the second airway. An aerosol formed by atomizing the aerosol-forming material 33 in the accommodating cavity 310 may flow into the suction nozzle 10 through the first airway, for a user to take. The aerosol-forming product 30 integrates the container 31 and the airway framework 380. Therefore, by replacing the entire aerosol-forming product 30, the aerosol-forming material 33 can be updated and the airway can be replaced at the same time, thereby accurately controlling the amount of the aerosol-forming material 33, ensuring cleanness of the airway, and effectively preventing health problems caused by non-timely and incomplete cleaning of the airway.

[0400] The holder 37 has a hollow tubular structure with two open ends. The container 31 has a hollow cylindrical structure with an open end. The open end of the container 31 is inserted into an axial end of the holder 37. The airway framework 380 has a hollow rotary structure. An axial end of the airway framework 380 is inserted into the other axial end of the holder 37. In this way, the container 31 and the airway framework 380 are respectively inserted into two axial ends of the holder 37 to be connected to each other through the holder 37. The container 31 is provided with only one opening at the top for communicating with the airway framework 380, and a communication hole is not provided at a bottom wall and a side wall thereof.

[0401] Further, the two axial ends of the holder 37 are respectively provided with a first clamping portion 371 and a second clamping portion 373. The open end of the container 31 is provided with a container clamping portion 3127 matching the first clamping portion 371. An axial end of the airway framework 380 is provided with a framework clamping portion matching the second clamping portion 373. In this way, the container clamping portion 3127 and the first clamping portion 371 are clamped with each other, and the second clamping portion 373 and the framework clamping portion are clamped with each other, so that the container 31, the holder 37, and the airway framework 380 form a non-detachable whole. It should be noted that, non-detachable means that disassembly is not implemented without being damaged, mainly to prevent the aerosol-forming product 30 from being secondarily added with the aerosol-forming material 33, and to achieve forced entire replacement.

[0402] Specifically, in an embodiment, an edge of an axial end of the holder 37 is folded inward, to form an annular first clamping portion 371. An edge of the open end of the container 31 is folded outward, to form an annular container clamping portion 3127. A lower surface of the container clamping portion 3127 is configured to abut against an upper surface of the first clamping portion 371. When a user attempts to pull the holder 37 and the container 31 apart from each other, the first clamping portion 371 may play a role of preventing the container clamping portion 3127 from moving, so as to prevent the holder 37 and the container 31 from being separated from each other.

[0403] An inner surface of a part of the side wall of the other axial end of the holder 37 protrudes outward, so as to form the second clamping portion 373 in the form of an annular protrusion. An outer surface of a part of the side wall of the airway framework 380 extending into the holder 37 is recessed inward, to form a framework clamping portion having an annular groove shape. The shape of the framework clamping portion matches the shape of the second clamping portion 373, so as to be embedded in the second clamping portion 373. When the user attempts to pull the holder 37 and the airway framework 380 apart from each other, the second clamping portion 373 may play a role of preventing the framework clamping portion from moving, so as to prevent the holder 37 and the airway framework 380 from being separated from each other.

[0404] It may be understood that an adaptation mode of the holder 37 to the container 31 and the airway framework 380 is not limited thereto. In some other embodiments, a non-detachable mode, such as screwing buckle connection or ultrasonic soldering may alternatively be used for assembly, thereby preventing the aerosol-forming product 30 from being disassembled by the user. In addition, the holder 37 and the container 31 or the holder 37 and the airway framework 380 may be integrally formed in a forming mode such as printing. The integral forming means that the holder 37 and the container 31 or the holder 37 and the airway framework 380 form an integral structure. The integral structure has features of the holder 37 and the container 31 or the holder 37 and the airway framework 380. In other words, the holder 37 may be omitted, and related features on the holder 37 may be formed on the container 31 or the airway framework 380.

[0405] Referring to FIG. 46 to FIG. 48 again, specifically, in some embodiments, the airway framework 380 includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. A lateral airway 383b is further provided in the framework body 383. An air inlet end of the lateral airway 383b is disposed on the side wall of the framework body 383 and extends radially into the framework body 383 from the outer surface of the side wall of the framework body 383. A connection hole communicated with the lateral airway 383b is provided in the framework body 383, and a central axis of the connection hole and a central axis of the framework body 383 overlap. One end of the central tube 384 is inserted into the connection hole, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0406] It may be understood that in some embodiments, the central tube 384 is detachably connected to the framework body 383. In some other embodiments, the central tube 384 and the airway framework 380 are integrally formed. As a preferred implementation, the central tube 384 is formed of a material such as metal or high temperature resistant plastic (for example, polyetheretherketone (PEEK)), thereby preventing the central tube 384 from being fused at a high temperature during an atomization process.

[0407] In this way, an end of the framework body 383 located outside the holder 37 forms an exhaust channel 383a communicated with the outside atmosphere. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The exhaust channel 383a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 384 forms a central airway 384a. The central airway 384a and the lateral airway 383b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 384a.

[0408] When a user inhales, air in the external environment may flow into the central airway 384a through the lateral airway 383b, flow to the bottom of the accommodating cavity 310 along the central airway 384a, and then flow into the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0409] As shown in FIG. 49 and FIG. 50, in some embodiments of the present disclosure, the airway framework 380 also includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. A lateral airway 383b is further provided in the framework body 383. An air inlet end of the lateral airway 383b is disposed on the side wall of the framework body 383 and extends radially into the framework body 383 from the outer surface of the side wall of the framework body 383. A connection hole communicated with the lateral airway 383b is provided in the framework body 383, and a central axis of the connection hole and a central axis of the framework body 383 overlap. One end of the central tube 384 is inserted into the connection hole, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0410] In this way, an end of the framework body 383 located outside the holder 37 forms an exhaust channel 383a communicated with the outside atmosphere. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The exhaust channel 383a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 384 forms a central airway 384a. The central airway 384a and the lateral airway 383b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 384a.

[0411] Different from the foregoing embodiments, an auxiliary airflow hole communicated with the edge airway 310a is further provided in the side wall of the framework body 383 of the airway framework 380 in this embodiment. An auxiliary air inlet hole communicating the auxiliary airflow hole with the outside atmosphere is provided in the side wall of the holder 37.

[0412] When a user inhales, air in the external environment may flow into the central airway 384a through the lateral airway 383b, flow to the bottom of the accommodating cavity 310 along the central airway 384a, and then flow into the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material33. At the same time, air in the external environment may further enter the edge airway 310a through the auxiliary air inlet hole and the auxiliary airflow hole, and then may be mixed with an aerosol in the edge airway 310a to reduce the concentration of the an aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing into the suction nozzle 10 is adjusted.

[0413] As shown in FIG. 51, in some embodiments, the airway framework 380 includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. One end of the central tube 384 is inserted into the framework body 383, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0414] In this way, an exhaust channel 383a communicated with the outside atmosphere is formed in an end of the framework body 383 located outside the holder 37. A central airway 384a is formed in the central tube 384. The central airway 384a and the exhaust channel 383a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 384a, and an opening at one end of the edge airway 310a is disposed on the side wall of the framework body 383, to form the foregoing first airway.

[0415] When a user inhales, air in the external environment may flow to the bottom of the accommodating cavity 310 through the edge airway 310a, and then flow into the suction nozzle 10 in sequence through the central airway 384a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0416] As shown in FIG. 52, and FIG. 53, in some embodiments, the airway framework 380 includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. One end of the central tube 384 is inserted into the framework body 383, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0417] In this way, an exhaust channel 383a communicated with the outside atmosphere is formed in an end of the framework body 383 located outside the holder 37. A central airway 384a is formed in the central tube 384. The central airway 384a and the exhaust channel 383a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 384a, and an opening at one end of the edge airway310a is disposed on the side wall of the framework body 383, to form the foregoing first airway.

[0418] Different from the foregoing embodiments, in this embodiment, a vent hole 384b is provided in a tube wall of the central tube 384. The vent hole 384b is communicated with outlet ends of the edge airway 310a and the central airway 384a.

[0419] When a user inhales, air in the external environment may flow to the bottom of the accommodating cavity 310 through the edge airway 310a, and then flow into the suction nozzle 10 in sequence through the central airway 384a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, airflow flowing from an edge air inlet 383d into the edge airway 310a may partially enter the central airway 384a through the vent hole 384b on the central tube 384, and may be mixed with an aerosol in the central airway 384a to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing into the suction nozzle 10 is adjusted.

[0420] Further, in some embodiments, as shown in FIG. 51 and FIG. 52, the aerosol-forming product 30 further includes a flow blocking baffle 39. The flow blocking baffle 39 is disposed on an inner wall of the exhaust channel 383a or the central airway 384a to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0421] Specifically, in an embodiment, the flow blocking baffle 39 includes a flow blocking top wall 392 and a flow blocking side wall 394 extending from the flow blocking top wall 392 in a same direction. An end of the flow blocking side wall 394 away from the flow blocking top wall 392 is inserted at an outlet end of the central airway 384a. The flow blocking top wall 392 shields the outlet end of the central airway 384a, and a lateral air outlet communicating the central airway 384a with the exhaust channel 383a is provided in the flow blocking side wall 394.

[0422] In this way, aerosol particles with a large diameter in the central airway 384a are adhered to the inner side of the outlet end of the central airway 384a or the flow blocking baffle 39 by collision, and will not enter the oral cavity of a user to affect the inhaling feeling. In addition, the flow blocking baffle 39 may shield the outlet end of the central airway 384a, to prevent the user from adding the aerosol-forming material 33 through the central airway 384a.

[0423] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, or an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0424] Referring to FIG. 47 and FIG. 48 again, in some embodiments, the aerosol-forming product 30 further includes an annular sealing member 385. The sealing member 385 is clamped between the container clamping portion 3127 and an end surface of the airway framework 380, to seal a clearance between the container 31 and the airway framework 380, thereby preventing airflow in the edge airway 310a from leaking from the clearance between the container 31 and the airway framework 380. It may be understood that in some other embodiments, sealing may be formed by an end surface interference contact and a radial interference contact, and the sealing member 385 is not required.

[0425] In some embodiments, the aerosol-forming product 30 further includes a damping member 386. The damping member 386 is sleeved outside the airway framework 380. Specifically, in an embodiment, an outer surface of the side wall of the airway framework 380 is formed with an annular accommodating groove extending along a peripheral direction, and the damping member 386 is annular to be embedded in the accommodating groove. When the aerosol-forming product 30 is inserted into an atomization device, the damping member 386 forms a particular damping with the atomization device, thereby preventing the aerosol-forming product 30 from sliding off the atomization device. It may be understood that a mode of improving connection stability between the aerosol-forming product 30 and the atomization device is not limited thereto, and a magnetic connection, a snapping connection, or a screwing buckle connection may alternatively be used.

[0426] Referring to FIG. 54 to FIG. 56, an aerosol-forming system 100 according to some embodiments of the present disclosure includes a housing 21, an atomizer 50, and a heating control assembly 27. The heating control assembly 27 is disposed in the housing 21. A cavity for accommodating the atomizer 50 is disposed at one end of the housing 21. The atomizer 50 is replaceably disposed in the cavity. An aerosol-forming material 33 is stored in the atomizer 50. The heating control assembly 27 is configured to supply heat to the cavity, so as to heat the aerosol-forming material 33 in the atomizer 50 to form an aerosol for a user to take.

[0427] After the aerosol-forming material 33 in the atomizer 50 is used up, the entire atomizer 50 may be pulled out from the heating control assembly 27 to replace a new atomizer 50, and the aerosol-forming material 33 in the atomizer 50 does not need to be manually added, thereby accurately controlling the amount and quality of the aerosol-forming material 33, and avoiding introduction of other impurities in a process of manually adding the aerosol-forming material.

[0428] Referring to FIG. 57 to FIG. 59, the atomizer 50 includes a container 31, a holder 37, and a suction nozzle 10. The container 31 has an accommodating cavity 310, with an open end, for accommodating the aerosol-forming material 33. An axial end of the holder 37 is adapted to the open end of the container 31. The suction nozzle 10 is adapted to the other axial end of the holder 37. The suction nozzle 10 includes a first airway and a second airway spaced apart, and the first airway and the second airway are respectively communicated with the accommodating cavity 310 and the outside atmosphere. To be specific, the first airway is communicated with the accommodating cavity 310 and the outside atmosphere, and the second airway is also communicated with the accommodating cavity 310 and the outside atmosphere. The two airways are separately spaced apart, and are communicated with each other through the accommodating cavity 310 in the atomizer 50.

[0429] In this way, the container 31 and the suction nozzle 10 are connected to each other through the holder 37. Air in the external environment may flow into the accommodating cavity 310 through one of the first airway and the second airway. An aerosol formed by atomizing the aerosol-forming material 33 in the accommodating cavity 310 may flow out through the other one of the first airway and the second airway, for a user to take. The atomizer 50 integrates the container 31, the suction nozzle 10, and the airway function. Therefore, by replacing the entire atomizer 50, the aerosol-forming material 33 can be updated and the suction nozzle 10 and the airway can be replaced at the same time, thereby accurately controlling the amount and quality of the aerosol-forming material 33, ensuring cleanness of the suction nozzle 10, and effectively preventing health problems caused by non-timely and incomplete cleaning of the suction nozzle 10.

[0430] The holder 37 has a hollow tubular structure with two open ends. The container 31 has a hollow cylindrical structure with an open end. The open end of the container 31 is inserted into an axial end of the holder 37. The suction nozzle 10 has a hollow rotary structure. An axial end of the suction nozzle 10 is inserted into the other axial end of the holder 37. In this way, the container 31 and the suction nozzle 10 are respectively inserted into two axial ends of the holder 37 to be connected to each other through the holder 37. The container 31 is provided with only one opening at the top for communicating with the suction nozzle 10, and a communication hole is not provided at a bottom wall and a side wall thereof.

[0431] Further, the two axial ends of the holder 37 are respectively provided with a first clamping portion 371 and a second clamping portion 373. The open end of the container 31 is provided with a container clamping portion 3127 matching the first clamping portion 371. An axial end of the suction nozzle 10 is provided with a suction nozzle clamping portion matching the first clamping portion 371. In this way, the container clamping portion 3127 and the first clamping portion 371 are clamped with each other, and the second clamping portion 373 and the suction nozzle clamping portion are clamped with each other, so that the container 31, the holder 37, and the suction nozzle 10 form a non-detachable whole.

[0432] Specifically, in an embodiment, an edge of an axial end of the holder 37 is folded inward, to form an annular first clamping portion 371. An edge of the open end of the container 31 is folded outward, to form an annular container clamping portion 3127. A lower surface of the container clamping portion 3127 is configured to abut against an upper surface of the first clamping portion 371. When a user attempts to pull the holder 37 and the container 31 apart from each other, the first clamping portion 371 may play a role of preventing the container clamping portion 3127 from moving, so as to prevent the holder 37 and the container 31 from being separated from each other.

[0433] An inner surface of a part of the side wall of the other axial end of the holder 37 protrudes outward, so as to form the second clamping portion 373 in the form of an arc protrusion. An outer surface of a part of the side wall of the suction nozzle 10 extending into the holder 37 is recessed inward, to form a suction nozzle clamping portion having an arc groove shape. The shape of the suction nozzle clamping portion matches the shape of the second clamping portion 373, so as to be embedded in the second clamping portion 373. When the user attempts to pull the holder 37 and the suction nozzle 10 apart from each other, the second clamping portion 373 may play a role of preventing the suction nozzle clamping portion from moving, so as to prevent the holder 37 and the suction nozzle 10 from being separated from each other.

[0434] It may be understood that an adaptation mode of the holder 37 to the container 31 and the holder 37 to the suction nozzle 10 is not limited thereto. In some other embodiments, a non-detachable mode, such as screwing buckle connection or soldering may alternatively be used for assembly, thereby preventing the atomizer 50 from being disassembled by the user. In addition, the holder 37 and the container 31 or the holder 37 and the suction nozzle 10 may be integrally formed in a forming mode such as 3D printing.

[0435] Referring to FIG. 57 to FIG. 59 again, specifically, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. A lateral airway 102b is further provided in the suction nozzle body 102. An air inlet end of the lateral airway 102b is disposed on the side wall of the suction nozzle body 102 and extends radially into the suction nozzle body 102 from the outer surface of the side wall of the suction nozzle body 102. A connection hole communicated with the lateral airway 102b is provided in the suction nozzle body 102, and a central axis of the connection hole and a central axis of the suction nozzle body 102 overlap. One end of the central tube 104 is inserted into the connection hole, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0436] It may be understood that in some embodiments, the central tube 104 is detachably connected to the suction nozzle body 102. In some other embodiments, the central tube 104 and the suction nozzle body 102 are integrally formed. As a preferred implementation, the central tube 104 is formed of a material such as metal or high temperature resistant plastic (for example, polyetheretherketone (PEEK)), thereby preventing the central tube 104 from being fused at a high temperature during an atomization process.

[0437] In this way, an end of the suction nozzle body 102 located outside the holder 37 forms an exhaust channel 102a communicated with the outside atmosphere. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The exhaust channel 102a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 104 forms a central airway 104a. The central airway 104a and the lateral airway 102b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 104a.

[0438] When a user inhales, air in the external environment may flow into the central airway 104a through the lateral airway 102b, flow to the bottom of the accommodating cavity 310 along the central airway 104a, and then flow out of the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0439] As shown in FIG. 60, and FIG. 61, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. A lateral airway 102b is further provided in a side wall of the suction nozzle body 102. An air inlet of the lateral airway 102b is disposed on the side wall of the suction nozzle body 102 and extends radially into the suction nozzle body 102 from the outer surface of the side wall of the suction nozzle body 102. A connection hole communicated with the lateral airway 102b is provided in the suction nozzle body 102, and a central axis of the connection hole and a central axis of the suction nozzle body 102 overlap. One end of the central tube 104 is inserted into the connection hole, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0440] In this way, an end of the suction nozzle body 102 located outside the holder 37 forms an exhaust channel 102a communicated with the atmosphere. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The exhaust channel 102a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 104 forms a central airway 104a. The central airway 104a and the lateral airway 102b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 104a.

[0441] Different from the foregoing embodiments, an auxiliary airflow hole 102c communicated with the edge airway 310a is further provided in the side wall of the suction nozzle body 102 in this embodiment. An auxiliary air inlet hole 375 communicating the auxiliary airflow hole 102c with the outside atmosphere is provided in the side wall of the holder 37.

[0442] When a user inhales, air in the external environment may flow into the central airway 104a through the lateral airway 102b, flow to the bottom of the accommodating cavity 310 along the central airway 104a, and then flow out of the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, air in the external environment may further enter the edge airway 310a through the auxiliary air inlet hole 375 and the auxiliary airflow hole 102c, and then may be mixed with an aerosol in the edge airway 310a to reduce the concentration of the an aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing out of the suction nozzle 10 is adjusted.

[0443] As shown in FIG. 56, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. One end of the central tube 104 is inserted into the suction nozzle body 102, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0444] In this way, an exhaust channel 102a communicated with the outside atmosphere is formed in an end of the suction nozzle body 102 located outside the holder 37. A central airway 104a is formed in the central tube 104. The central airway 104a and the exhaust channel 102a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 104a, and an opening at one end of the edge airway 310a is disposed on the side wall of the suction nozzle body 102, to form the foregoing first airway.

[0445] When a user inhales, air in the external environment may flow to the bottom of the accommodating cavity 310 through the edge airway 310a, and then flow out of the suction nozzle 10 in sequence through the central airway 104a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0446] As shown in FIG. 63, and FIG. 64, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. One end of the central tube 104 is inserted into the suction nozzle body 102, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0447] In this way, an exhaust channel 102a communicated with the atmosphere is formed in an end of the suction nozzle body 102 located outside the holder 37. A central airway 104a is formed in the central tube 104. The central airway 104a and the exhaust channel 102a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 104a, and an opening at one end of the edge airway 310a is disposed on the side wall of the suction nozzle 10, to form the foregoing first airway. As an alternative solution of an opening at one end of the edge airway 310a, an air clearance may be provided between the side wall of the suction nozzle10 and the holder 37. The air clearance is communicated with the edge airway 310a.

[0448] Different from the foregoing embodiments, in this embodiment, a vent hole 104b is provided in a tube wall of the central tube 104. The vent hole 104b is communicated with outlet ends of the edge airway 310a and the central airway 104a.

[0449] When a user inhales, air in the external environment may flow into the accommodating cavity 310 through the edge airway 310a, and then flow out of the suction nozzle 10 in sequence through the central airway 104a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, airflow flowing into the edge airway 310a may partially enter the outlet end of the central airway 104a through the vent hole 104b, and may be mixed with an aerosol in the central airway 104a to adjust the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing out of the suction nozzle 10 is adjusted.

[0450] Further, in some embodiments, as shown in FIG. 62 and FIG. 63, the atomizer 50 further includes a flow blocking baffle 55. The flow blocking baffle 55 is disposed on an inner wall of the exhaust channel 102a or the central airway 104a to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0451] Specifically, in an embodiment, the flow blocking baffle 55 includes a flow blocking top wall 552 and a flow blocking side wall 554 extending from the flow blocking top wall 552 in a same direction. An end of the flow blocking side wall 554 away from the flow blocking top wall 552 is inserted at an outlet end of the central airway 104a. The flow blocking top wall 552 shields the outlet end of the central airway 104a, and a lateral air outlet communicating the central airway 104a with the exhaust channel 102a is provided in the flow blocking side wall 554.

[0452] In this way, aerosol particles with a large diameter in the central airway 104a are adhered to the inner side of the outlet end of the central airway 104a or the flow blocking baffle 55 by collision, and will not enter the oral cavity of a user to affect the inhaling feeling. In addition, the flow blocking baffle 55 may shield the outlet end of the central airway 104a, to prevent the user from adding the aerosol-forming material 33 through the central airway 104a.

[0453] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, or an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0454] In some embodiments, the atomizer 50 further includes a first sealing member 105 and a second sealing member 106 that are annular. The first sealing member 105 is disposed at a joint between the container clamping portion 3127 and the suction nozzle body 102, to seal a clearance between the container 31 and the suction nozzle body 102, thereby preventing airflow in the first edge airway 310a and the second edge airway 310a from leaking from a clearance between the container 31 and the suction nozzle 10. The second sealing member 106 is disposed at a joint between the suction nozzle 10 and the holder 37, so as to seal a clearance between the suction nozzle 10 and the holder 37 and avoid air leakage. In addition, when the atomizer 50 is inserted into the housing 21, a particular amount of damping is formed between the second sealing member 106 and the housing 21, so as to prevent the atomizer 50 from sliding off the housing 21.

[0455] It may be understood that in some other embodiments, sealing may be formed by an end surface interference contact and a radial interference contact, and the first sealing member 105 and the second sealing member 106 are not required. A mode of improving stability of connection between the atomizer 50 and the heating control assembly 27 is not limited thereto, and a magnetic connection, a snapping connection, or a screwing buckle connection may alternatively be used.

[0456] As shown in FIG. 65 to FIG. 68, an aerosol-forming system 100 according to a thirty-fifth embodiment of the present disclosure includes a housing 21, an atomizer 50, and a heating control assembly 27. The heating control assembly 27 is disposed in the housing 21. One end of the housing 21 is provided with a cavity for accommodating the atomizer 50. The atomizer 50 is separably disposed in the cavity. The atomizer 50 includes an aerosol-forming product 30 and a suction nozzle assembly 60. The aerosol-forming product 30 stores an aerosol-forming material 33. The suction nozzle assembly 60 is separably adapted to the aerosol-forming product 30. The heating control assembly 27 may heat the atomized aerosol-forming material 33 in the aerosol-forming product 30 to form an aerosol, and the aerosol may flow out through the suction nozzle assembly 60 for a user to take.

[0457] After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the entire atomizer 50 may be pulled out from the housing 21, and the aerosol-forming product 30 is separated from the suction nozzle assembly 60 to replace a new aerosol-forming product 30. The aerosol-forming material 33 in the aerosol-forming product 30 does not need to be manually added, thereby accurately controlling the amount and quality of the aerosol-forming material 33, and avoiding introduction of other impurities in a process of manually adding the aerosol-forming material.

[0458] The aerosol-forming product 30 includes a container 31, a sealing film 351, and the aerosol-forming material 33. The container 31 has a hollow tubular structure. The container 31 has an accommodating cavity 310 with an open end. The sealing film 351 is encapsulated at the open end of the container 31 to seal the accommodating cavity 310. Because the container 31 is sealed by the sealing film 351, air may be insulated, to prevent the aerosol-forming material 33 from oxidative deterioration, and a user is prevented from introducing impurities due to voluntary adding of the aerosol-forming material 33 to the accommodating cavity 310, thereby ensuring the quality of the aerosol-forming material 33.

[0459] The suction nozzle assembly 60 includes a suction nozzle 10 and a piercing air tube 61. The suction nozzle 10 has a hollow rotary structure, and has a first airway and a second airway that are communicated with the atmosphere and are spaced apart. One end of the piercing air tube 61 is adapted to one end of the suction nozzle 10 and is communicated with the first airway, and the other end of the piercing air tube 61 extends out of the suction nozzle 10. When the suction nozzle 10 is adapted to the aerosol-forming product 30, the suction nozzle 10 covers the open end of the container 31, and one end of the piercing air tube 61 may pierce the sealing film 351 into the accommodating cavity 310.

[0460] In this way, the piercing air tube 61 is communicated with the accommodating cavity 310 of the aerosol-forming product 30 and the first airway of the suction nozzle 10, and a gap between a side wall of the piercing air tube 61 and a cavity wall of the accommodating cavity 310 is communicated with the second airway. In some embodiments, outside air may flow into the accommodating cavity 310 through the first airway and the piercing air tube 61, and then flow into the second airway through the gap between the side wall of the piercing air tube 61 and the cavity wall of the accommodating cavity 310 by carrying an aerosol formed by atomizing the aerosol-forming material 33. In some other embodiments, the outside air may flow into the accommodating cavity 310 in sequence through the second airway and the gap between the side wall of the piercing air tube 61 and the cavity wall of the accommodating cavity 310, and then flow into the first airway by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0461] Before the atomizer 50 is used, the sealing film 351 of the aerosol-forming product 30 is pierced by using the piercing air tube 61 of the suction nozzle assembly 60, and then the entire atomizer 50 is inserted into the cavity of the aerosol-forming system 100. After activation, inhaling may be implemented. After the aerosol-forming material 33 is used up, the entire atomizer 50 may be pulled out from the aerosol-forming system 100, and then the suction nozzle assembly 60 is pulled out from the atomizer 50, to replace a new aerosol-forming product 30.

[0462] Specifically, a plurality of ridges 61a are convexly disposed on an outer side wall of the piercing air tube 61. All the ridges 61a are spaced apart along a peripheral direction of the piercing air tube 61. Each ridge 61a extends along an axial direction of the piercing air tube 61. In this way, after the piercing air tube 61 extends into the accommodating cavity 310, a gap communicated with the second airway is defined between two adjacent ridges 61a and the cavity wall of the accommodating cavity 310. It may be understood that the quantity and shape of the ridges 61a are not limited thereto, and may be set according to requirements to satisfy different requirements. It should be noted that, to avoid leakage of the aerosol after piercing, the sealing film 351 may be made of an elastic material, such as silica gel, PET, PP, or an aluminum plastic film. In addition, to ensure an appropriate depth of insertion of the piercing air tube 61 into the container 31, a limiting portion may further be disposed on the piercing air tube 61. For example, an outer wall of the piercing air tube 61 and an open end surface of a tube body form an abutting portion. There are a plurality of implementation structures, which are not described herein one by one.

[0463] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and one end of the edge airway 107a is communicated with the exhaust channel 101a. A lateral airway is further disposed in the suction nozzle 10. An air inlet end of the lateral airway is provided in a side wall of the inhaling portion 101, and an air outlet end of the lateral airway is communicated with the central airway 103a. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0464] In this way, the exhaust channel 101a and the edge airway 107a are communicated with each other to jointly form a first airway, and the exhaust channel 101a is disposed at an end of the suction nozzle 10 communicated with the outside atmosphere. The central airway 103a and the lateral airway jointly form a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. An end of the edge airway 107a away from the exhaust channel 101a is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0465] When a user inhales by using the suction nozzle 10, air in the external environment may flow into the accommodating cavity 310 in sequence through the lateral airway, the central airway 103a, and the piercing air tube 61, and then flow out of the suction nozzle 10 in sequence through the edge airway 107a and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0466] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and one end of the edge airway 107a is communicated with the exhaust channel 101a. A lateral airway is further disposed in the suction nozzle 10. An air inlet end of the lateral airway is provided in a side wall of the inhaling portion 101, and an air outlet end of the lateral airway is communicated with the central airway 103a. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0467] In this way, the exhaust channel 101a and the edge airway 107a are communicated with each other to jointly form a first airway, and the exhaust channel 101a is disposed at an end of the suction nozzle 10 communicated with the atmosphere. The central airway 103a and the lateral airway jointly form a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. An end of the edge airway 107a away from the exhaust channel 101a is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0468] An auxiliary airflow hole is provided in a side wall of the second connection portion 107 of the suction nozzle 10. The auxiliary airflow hole is communicated with the edge airway 107a. When a user inhales by using the suction nozzle 10, air in the external environment may flow into the accommodating cavity 310 in sequence through the lateral airway, the central airway 103a, and the piercing air tube 61, and then flow out of the suction nozzle 10 in sequence through the edge airway 107a and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, air in the external environment may further enter the edge airway 107a from the auxiliary air inlet hole, and then may be mixed with an aerosol in the edge airway 107a to reduce the concentration of the an aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing out of the suction nozzle 10 is adjusted.

[0469] Further, in some implementations, the suction nozzle assembly 60 further includes a flow blocking baffle 65. The flow blocking baffle 65 is disposed on an inner wall of the exhaust channel 101a or the central airway 103a to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0470] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a that is communicated with the exhaust channel 101a and disposed coaxially with the exhaust channel 101a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and an air inlet end of the edge airway 107a is provided in the side wall of the second connection portion 107 of the suction nozzle 10. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0471] In this way, the exhaust channel 101a and the central airway 103a are communicated with each other to jointly form a first airway, and the edge airway 107a forms a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. The second airway is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0472] When a user inhales by using the suction nozzle 10, air in the external environment may enter the suction nozzle 10 from the edge airway 107a and reach the bottom of the accommodating cavity 310, and then flow out of the suction nozzle 10 in sequence through the piercing air tube 61, the central airway 103a, and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0473] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a that is communicated with the exhaust channel 101a and disposed coaxially with the exhaust channel 101a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and an air inlet end of the edge airway 107a is provided in the side wall of the second connection portion 107 of the suction nozzle 10. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0474] In this way, the exhaust channel 101a and the central airway 103a are communicated with each other to jointly form a first airway, and the edge airway 107a forms a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. The second airway is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0475] A vent hole communicated with the edge airway 107a is provided with an airway wall (i.e. the side wall of the second connection portion 107) of the central airway 103a. In this way, when a user inhales by using the suction nozzle 10, air in the external environment may enter the suction nozzle 10 from the edge airway 107a and reach the bottom of the accommodating cavity 310, and then flow out of the suction nozzle 10 in sequence through the piercing air tube 61, the central airway 103a, and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, a part of the airflow flowing into the edge airway 107a may partially flow into the central airway 103a through the vent hole, and may be mixed with an aerosol in the central airway 103a to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing out of the suction nozzle 10 is adjusted.

[0476] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, and an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0477] According to the foregoing aerosol-forming product 30 and aerosol-forming system 100, the aerosol-forming product 30 pre-loaded with the aerosol-forming material 33 may be separately connected to the suction nozzle assembly 60. The aerosol-forming material 33 can be updated by replacing the aerosol-forming product 30 without manually adding the aerosol-forming material 33 by a user, thereby accurately controlling the amount of the aerosol-forming material 33, and ensuring the quality of the aerosol-forming material 33.

[0478] Referring to FIG. 69 and FIG. 70, an atomizer 50 according to some embodiments of the present disclosure includes an aerosol-forming product 30 and a suction nozzle assembly 60. The aerosol-forming product 30 includes a container 31 having an accommodating cavity 310 formed therein and a heating element 32 disposed in the accommodating cavity 310. The suction nozzle assembly 60 may be separately adapted to the aerosol-forming product 30, or may be adapted to the aerosol-forming product 30 in a non-detachable mode.

[0479] The suction nozzle assembly 60 includes a suction nozzle 10 and an air guide tube 13. An exhaust channel 112 is formed in the suction nozzle 10, and an aerosol formed by atomization in the accommodating cavity 310 can be outputted to the outside through the exhaust channel 112, for a user to take or inhale. Further, at least one lateral airway 121 may be further formed on the suction nozzle 10, for allowing outside air to enter the accommodating cavity 310. Specifically, in this embodiment, there are two lateral airways 121. The two lateral airways 121 are respectively located at two transverse opposite sides of the suction nozzle 10, and respectively extend inward from outer surfaces of two sides of the suction nozzle 10. In other embodiments, there may alternatively be one or more lateral airways 121.

[0480] An inner wall surface of the air guide tube 13 defines an air guide channel 130. The air guide channel 130 may be configured for air inlet or air outlet to / from the accommodating cavity 310. An upper end of the air guide tube 13 may be embedded in the suction nozzle 10, and may be adapted to the suction nozzle 10 in a detachable or non-detachable mode. A lower end of the air guide tube 13 may extend into the accommodating cavity 310 and is spaced apart from a bottom wall of the container 31. An outer diameter of a tubular side wall 131 is smaller than an inner diameter of the container 31, so that an annular vent clearance 3111 is formed between an outer wall surface of the tubular side wall 131 and an inner wall surface of the container 31. One of the vent clearance 3111 and the air guide channel 130 is configured for air inlet, and the other is configured for air outlet. In other embodiments, the lower end of the air guide tube 13 may alternatively not extend into the accommodating cavity 310.

[0481] Specifically, in this embodiment, the air guide channel 130 is communicated with the exhaust channel 112, and the vent clearance 3111 is communicated with the lateral airway 121. Outside air may flow into the accommodating cavity 310 in sequence through the lateral airway 121 and the vent clearance 3111, and then flow out in sequence through the air guide channel 130 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33. In other embodiments, the air guide channel 130 may alternatively be communicated with the lateral airway 121, and the vent clearance 3111 may alternatively be communicated with the exhaust channel 112. Outside air may flow into the accommodating cavity 310 in sequence through the lateral airway 121 and the air guide channel 130, and then flow out in sequence through the vent clearance 3111 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0482] In some embodiments, the air guide tube 13 may be made of a non-ferromagnetic metal material, so as to avoid dry heating of the air guide tube 13. In addition, the metal material has advantages such as high temperature resistance, no pollution, no odor, and low costs. An upper end of the air guide tube 13 may be embedded into the suction nozzle 10 by riveting, and fixed to the suction nozzle 10 together. In other embodiments, the air guide tube 13 may alternatively be made of another high temperature resistant material, such as high temperature resistant plastic (for example, polyetheretherketone).

[0483] In some embodiments, the air guide tube 13 may include a tubular side wall 131 having a circular tube shape (alternatively, having another shape such as an elliptic tube shape or a square tube shape) and a bottom wall 132 disposed at a lower end of the tubular side wall 131. The tubular side wall 131 and the bottom wall 132 jointly define the air guide channel 130 with an open upper end. The tubular side wall 131 is provided with at least one vent hole 1310 communicating the air guide channel 130 with the accommodating cavity 310.

[0484] The bottom wall 132 is disposed at a lower end of the tubular side wall 131 and seals the lower end of the tubular side wall 131. The accommodating cavity 310 is communicated with the air guide channel 130 via the vent hole 1310 in the tubular side wall 131, so as to effectively prevent from directly inhaling the aerosol-forming material 33 into the air guide channel 130 during inhaling, thereby improving user experience. In addition, a cross-sectional through-flow area of a single vent hole 1310 is relatively small, which assists in preventing the aerosol-forming material 33 from being drawn out.

[0485] Preferably, the tubular side wall 131 is provided with a plurality of vent holes 1310. The plurality of vent holes 1310 may be evenly spaced apart in a peripheral direction and / or an axial direction of the tubular side wall 131, to assist airflow in evenly entering the air guide channel 130. The shape of each vent hole 1310 is not limited, and may be various shapes such as a circular hole shape, an elliptic hole shape, and a square hole shape. In some embodiments, the plurality of vent holes 1310 may be disposed close to the bottom wall 132, which assists in sufficiently drawing out an aerosol formed by atomizing the aerosol-forming material 33.

[0486] In other embodiments, the plurality of vent holes 1310 may alternatively be provided in the bottom wall 132, or may be provided in both the bottom wall 132 and the tubular side wall 131, which also assists in preventing the aerosol-forming material 33 from entering the air guide channel 130. In some other embodiments, the air guide tube 13 may not be provided with the bottom wall 132, and the air guide channel 130 may be zigzagged and / or a porous material may be disposed in the air guide channel 130, to prevent the aerosol-forming material 33 from splashing out of the air guide channel 130. Alternatively, a flow blocking structure may be disposed in the air guide channel 130 to block a part of the air guide channel 130, so as to prevent the aerosol-forming material 33 from splashing out of the air guide channel 130. The porous material may alternatively be directly used as an airway, and air inlet or air outlet is implemented by using micro-pores in the porous material.

[0487] In some embodiments, the suction nozzle assembly 60 may further include a connector 62. The connector 62 is at least partially disposed between an outer wall surface of the container 31 and an inner wall surface of the suction nozzle 10, and may be made of an elastic material such as silica gel. On one hand, the connector 62 made of an elastic material has good sealing performance. On the other hand, an upper end of the container 31 may be plugged into the connector 62. The container 31 is connected to the connector 62 in a pluggable mode, so that the container 31 can be conveniently assembled and disassembled in a pluggable mode. Therefore, it may be convenient to remove the container 31 from the suction nozzle assembly 60 and then add the aerosol-forming material 33 to the container 31.

[0488] It may be understood that in other embodiments, the connector 62 may alternatively be made of another material such as high temperature resistant plastic. In some other embodiments, the connector 62 may alternatively be omitted, and the container 31 may be directly plugged into the suction nozzle 10. In addition, the aerosol-forming material 33 can be updated by replacing the entire atomizer 50, so as to avoid a problem of cleaning the atomizer 50. In this way, the suction nozzle assembly 60 and the container 31 may alternatively be connected in a non-detachable mode.

[0489] In some embodiments, the connector 62 may include an annular sleeve portion 621 and an annular connection portion 622 extending inward from an inner wall surface of the sleeve portion 621. The sleeve portion 621 may be disposed between an outer wall surface of the container 31 and an inner wall surface of the suction nozzle 10 in a sealing mode. The connection portion 622 may abut against an upper end surface of the container 31, and have a through hole 6220 for passage of the air guide tube 13 and at least one vent hole 6221 communicating the lateral airway 121 with the vent clearance 3111 formed through.

[0490] The through hole 6220 may be provided in the middle of the connection portion 622. A lower end of the air guide tube 13 may pass through the through hole 6220 and further extend into the accommodating cavity 310, and an outer wall surface of the air guide tube 13 may be in sealing fit with a hole wall surface of the through hole 6220. There may be a plurality of vent holes 6221. The plurality of vent holes 6221 may surround the outer periphery of the through hole 6220 and may be evenly spaced apart in the peripheral direction, facilitating airflow to evenly enter the accommodating cavity 310.

[0491] During inhaling, outside air enters through the lateral airways 121 on two sides of the suction nozzle 10, enters the accommodating cavity 310 through the vent hole 6221 on the connector 62, and is mixed with the aerosol in the accommodating cavity 310. Then, the mixed airflow enters the air guide channel 130 through the vent hole 1310 on the air guide tube 13, and further flows out through the exhaust channel 112.

[0492] Further, the aerosol-forming product 30 may further include a limiting member 34 disposed in the container 31, for limiting the heating element 32 in the container 31. The limiting member 34 may be made of a high temperature resistant material, such as metal or non-metal. Preferably, the limiting member 34 may be made of a non-ferromagnetic metal material, so as to prevent dry heating of the limiting member 34. In addition, the metal material has advantages such as high temperature resistance, no pollution, no odor, and low costs.

[0493] Specifically, in this embodiment, the limiting member 34 may include a sheet-like body 3411. The sheet-like body 3411 is provided with a plurality of airflow through holes 3410 for passage of airflow. The sheet-like body 3411 may abut against an upper end of the heating element 32, so as to press the heating element 32 against a bottom wall of the container 31. The sheet-like body 3411 further assists in reducing or preventing the aerosol-forming material 33 from splashing out when the aerosol-forming material 33 is heated.

[0494] In this embodiment, an outer diameter of the sheet-like body 3411 is smaller than an inner diameter of the container 31. The limiting member 34 further includes at least two limiting arms 3413 disposed on the outer periphery of the sheet-like body 3411. The limiting member 34 is limited by contact between the at least two limiting arms 3413 and the container 31. Preferably, the at least two limiting arms 3413 are elastic arms and are evenly spaced apart in a peripheral direction of the sheet-like body 3411, facilitating even stressing, and being elastically pressed against the inner wall surface of the container 31 by means of an elastic force. A lower end of each limiting arm 3413 is connected to the sheet-like body 3411, and an upper end is expanded outward by an angle to be elastically pressed against the inner wall surface of the container 31.

[0495] In other embodiments, the limiting member 34 may alternatively not include the limiting arm 3413. For example, several convex hulls may be formed by extending at least a part of an outer peripheral surface of the sheet-like body 3411 outward, and the several convex hulls abut against the inner wall surface of the container 31 to implement limiting. Alternatively, the heating element 32 may be pressed against the bottom wall of the container 31 after the bottom wall 132 of the air guide tube 13 abuts against the sheet-like body 3411.

[0496] Referring to FIG. 71, an atomizer 50 according to some embodiments of the present disclosure includes an aerosol-forming product 30 and a suction nozzle assembly 60. The aerosol-forming product 30 includes a container 31 having an accommodating cavity 310 formed therein, and a heating element 32 and an aerosol-forming material 33 disposed in the accommodating cavity 310. The suction nozzle assembly 60 may be separately adapted to the aerosol-forming product 30, or may be adapted to the aerosol-forming product 30 in a non-detachable mode.

[0497] The suction nozzle assembly 60 includes a suction nozzle 10, an air inlet tube 133, and an air outlet tube 134. The suction nozzle 10 has an exhaust channel 112 and a lateral airway 121 that are respectively communicated with the atmosphere. An air inlet channel 1330 and an air outlet channel 1340 are respectively formed in the air inlet tube 133 and the air outlet tube 134. One end of the air inlet tube 133 is adapted to the suction nozzle 10 and is communicated with the lateral airway 121, and the other end of the air inlet tube 133 extends into the container 31 and is communicated with the accommodating cavity 310. One end of the air outlet tube 134 is adapted to the suction nozzle 10 and is communicated with the exhaust channel 112, and the other end of the air outlet tube 134 extends into the container 31 and is communicated with the accommodating cavity 310. Outside air may flow into the accommodating cavity 310 in sequence through the lateral airway 121 and the air inlet channel 1330, and then flow out in sequence through the air outlet channel 1340 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0498] The air inlet tube 133 and the air outlet tube 134 may alternatively be sleeved with each other. For example, the air outlet tube 134 may be sleeved outside the air inlet tube 133. The air inlet channel 1330 is formed in the air inlet tube 133. The air outlet channel 1340 is formed between an outer wall surface of the air inlet tube 133 and an outer wall surface of the air outlet tube 134. Alternatively, the air inlet tube 133 may be sleeved outside the air outlet tube 134. The air outlet channel 1340 is formed in the air outlet tube 134. The air inlet channel 1330 is formed between an outer wall surface of the air outlet tube 134 and an outer wall surface of the air inlet tube 133.

[0499] In some embodiments, the suction nozzle assembly 60 further includes a connector 62. The connector 62 is embedded in one end of the suction nozzle 10, and is formed with an air inlet hole 623 communicated with the lateral airway 121 and an air outlet hole 624 communicated with the exhaust channel 112. One end of the air inlet tube 133 may be embedded in the air inlet hole 623 and communicated with the air inlet hole 623. One end of the air outlet tube 134 may be embedded in the air outlet hole 624 and communicated with the air outlet hole 624. An open end of the container 31 is embedded in an end of the connector 62 away from the exhaust channel 112, and may be fixed to the connector 62 together by interference fit or snapping connection.

[0500] As a preferred implementation, the connector 62 may be made of an elastic material such as silica gel. On one hand, the connector 62 made of an elastic material has good sealing performance. On the other hand, upper ends of the container 31, the air inlet tube 133, and the air outlet tube 134 may be plugged into the connector 62. The container 31, the air inlet tube 133, the air outlet tube 134, and the connector 62 can be conveniently assembled and disassembled in a pluggable mode. Therefore, it may be convenient to remove the container 31 from the connector 62 and then add the aerosol-forming material 33 to the container 31, and it may be further convenient to separately replace the air inlet tube 133 and the air outlet tube 134. In other embodiments, the connector 62 may alternatively be made of another material such as high temperature resistant plastic. In some other embodiments, the connector 62 may be integrally formed with the suction nozzle 10, and / or, the connector 62 may be integrally formed with the air inlet tube 133 and the air outlet tube 134.

[0501] FIG. 72 to FIG. 75 show an atomizer 50 according to some embodiments of the present disclosure. The atomizer 50 in this embodiment also includes an aerosol-forming product 30, a suction nozzle 10, and a connector 62. For structures of the aerosol-forming product 30 and the suction nozzle 10, refer to the foregoing descriptions. Details are not described herein again.

[0502] The connector 62 in this embodiment includes an annular sleeve portion 621 and an annular airway portion 625. The sleeve portion 621 surrounds outside the airway portion 625 and may be coaxially disposed with the airway portion 625, but is not limited to being coaxially disposed. An inner wall surface of the airway portion 625 defines an air guide channel 6250, and an inner wall surface of the sleeve portion 621 and an outer wall surface of the airway portion 625 defines an air guide channel 6210. One of the air guide channel 6210 and the air guide channel 6250 may be configured for air inlet of the accommodating cavity 310, and the other is configured for air outlet of the accommodating cavity 310.

[0503] The container 31 may be sleeved between an outer wall surface of the sleeve portion 621 and an inner wall surface of the suction nozzle 10. In other embodiments, the container 31 may alternatively be sleeved in the sleeve portion 621. At this moment, the air guide channel 6210 may be formed between the inner wall surface of the container 31 and the outer wall surface of the air guide portion 625.

[0504] Further, the connector 62 further includes a connection portion 622. The sleeve portion 621 and the airway portion 625 respectively extend from one end surface of the connection portion 622 along a same direction. Specifically, in this embodiment, the sleeve portion 621 and the airway portion 625 respectively extend downward from a lower end surface of the connection portion 622 along an axial direction. The air guide channel 6250 extends through the connection portion 622, so as to communicate with one of the lateral airway 121 on the suction nozzle 10 and the exhaust channel 112. The air guide channel 6210 does not extend through the connection portion 622. The connection portion 622 is provided with at least one vent hole 6222, to communicate the air guide channel 6210 with the other one of the lateral airway 121 and the exhaust channel 112. Specifically, in this embodiment, the air guide channel 6210 is communicated with the exhaust channel 112, and the air guide channel 6250 is communicated with the lateral airway 121.

[0505] In other embodiments, a lower end surface of the connection portion 622 may alternatively extend downward to form at least two tubular airway portions 625, and air inlet and air outlet to / from the accommodating cavity 310 are implemented by using the at least two tubular airway portions 625.

[0506] In some embodiments, a communication channel 6224 communicating the air guide channel 6250 with the lateral airway 121 may be further formed between the connection portion 622 and the suction nozzle 10. The communication channel 6224 may be formed by recessing the suction nozzle 10 or the connection portion 622, or may be formed by jointly recessing the suction nozzle 10 and the connection portion 622. In this embodiment, a communication groove 6223 communicated with an upper end of the air guide tube 6250 is formed by recessing an upper end surface of the connection portion 622. The communication groove 6223 extends through two transverse sides of the connection portion 622. After the connector 62 is loaded into the suction nozzle 10, an upper end surface of the communication groove 6223 is covered by the suction nozzle 10 to form the communication channel 6224. Two transverse ends of the communication channel 6224 are respectively communicated with two lateral airways 121 on the suction nozzle 10. There are two vent holes 6222. The two vent holes 6222 are respectively located on two opposite sides of the communication groove 6223.

[0507] FIG. 76 and FIG. 77 show an atomizer 50 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that in this embodiment, the airway portion 625 has an approximately C-shaped tube shape. The airway portion 625 has an opening 6251 on a peripheral side. The opening 6251 is covered by an inner wall surface of one side of the sleeve portion 621 and / or an inner wall surface of one side of the container 31 to form an air guide channel 6250. An air guide channel 6210 is formed between an outer surface of the airway portion 625 away from the opening 6251 and an inner wall surface of the other side of the sleeve portion 621 and / or an inner wall surface of the other side of the container 31.

[0508] Specifically, in this embodiment, an upper end of the container 31 is sleeved in the sleeve portion 621 and is disposed coaxially with the sleeve portion 621. The airway portion 625 is eccentrically disposed relative to a central axis of the sleeve portion 621. An air guide channel 6250 is formed between an inner surface of a side of the airway portion 625 close to the opening 6251 and an inner surface of the container 31. An air guide channel 6210 is formed between an outer surface of a side of the airway portion 625 away from the opening 6251 and the inner surface of the container 31. The air guide channel 6250 is communicated with the lateral airway 121, and the air guide channel 6210 is communicated with the exhaust channel 112.

[0509] Similar to the foregoing embodiments, in this embodiment, a communication channel 6224 communicating the air guide channel 6250 with the lateral airway 121 is formed between the connection portion 622 and the suction nozzle 10. To be different, in this embodiment, because the air guide channel 6250 is eccentrically disposed, the communication channel 6224 does not extend through two transverse sides of the connection portion 622. Specifically, the communication channel 6224 may extend from one side of the connection portion 622 along a transverse direction to be communicated with the air guide channel 6250.

[0510] In other embodiments, any variation may alternatively be made to the foregoing structure according to requirements. For example, the container 31 may be sleeved between an outer wall surface of the sleeve portion 621 and an inner wall surface of the suction nozzle 10. For another example, the air guide channel 6250 may alternatively be communicated with the exhaust channel 112. Correspondingly, the air guide channel 6210 is communicated with the lateral airway 121.

[0511] FIG. 78 shows an atomizer 50 according to some embodiments of the present disclosure. The atomizer 50 in this embodiment also includes an aerosol-forming product 30, a suction nozzle 10, and a connector 62. To be different, at least one vent hole 3101 is provided in the container 31 in this embodiment, and is configured for air inlet or air outlet to / from the accommodating cavity 310.

[0512] Specifically, in this embodiment, a container side wall 312 of the container 31 is provided with a plurality of vent holes 3101 communicating the accommodating cavity 310 with the outside. The plurality of vent holes 3101 may be evenly spaced apart in a peripheral direction of the container side wall 312. The connector 62 is provided with an airflow channel 627 communicated with the accommodating cavity 310. Outside air may enter the accommodating cavity 310 from the plurality of vent holes 3101, and then flow out of the suction nozzle 10 in sequence through the airflow channel 627 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33. The accommodating cavity 310 implements air inlet by using the plurality of vent holes 3101, so that a channel for air inlet may not be required for the suction nozzle 10.

[0513] It may be understood that in other embodiments, the plurality of vent holes 3101 may be evenly spaced apart in an axial direction of the container side wall 312, or may be spaced apart in both a peripheral direction and an axial direction of the container side wall 312. There may alternatively be only one vent hole 3101. In addition, the vent hole 3101 may alternatively be provided in the container bottom wall 313 of the container 31.

[0514] In another embodiment, the accommodating cavity 310 may implement air outlet by using the plurality of vent holes 3101, and an aerosol formed by atomizing the aerosol-forming material 33 flows out of the suction nozzle 10 in sequence through the plurality of vent holes 3101 and the exhaust channel 112.

[0515] FIG. 79 to FIG. 80 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 includes a container 31, a heating element 32, and an aerosol-forming material 33. An accommodating cavity 310 having an opening 311 at one end is formed in the container 31. The heating element 32 and the aerosol-forming material 33 are accommodated in the accommodating cavity 310. The heating element 32 includes a sensor material or is made of a sensor material, and is configured to generate heat in a magnetic field, to heat the aerosol-forming material 33.

[0516] The heating element 32 has a sheet-like structure (including a planar sheet-like structure and / or a non-planar sheet-like structure), and a specific shape thereof is not limited. It is set that the heating element 32 has a longitudinal direction Y1, a transverse direction Y2, and a transverse direction Y3 that are perpendicular to each other. The longitudinal direction Y1 is parallel to an axial direction of the container 31. When the heating element 32 is placed in the magnetic field, the longitudinal direction Y1 is further approximately parallel to a direction of the magnetic field. In some embodiments, the heating element 32 includes a heating main body 326. The heating main body 326 has a sheet-like structure and may be a geometric body formed by extending a geometrical surface along a direction. The extending direction may be parallel to an axis direction of the container 31 or form a preset angle.

[0517] Preferably, the heating main body 326 is partially exposed to the aerosol-forming material 33. In this way, during operation, the part of the heating main body 326 exposed to the aerosol-forming material 33 can rapidly heat up and atomize a part of liquid, which is beneficial to rapid smoke output. On the contrary, if the heating main body 326 is completely immersed in the liquid, the entire liquid can be atomized only after being heated, and it is difficult to achieve an objective of rapid smoke output. It should be noted that, in some embodiments, that the heating main body 326 is partially exposed to the aerosol-forming material 33 may include the following understanding: when the aerosol-forming material 33 is in a liquid state and in an initial state of being not heated, in a direction Y1, an upper end of the heating main body 326 is higher than a liquid level, and a lower end of the heating main body 326 is in contact with the bottom of the container 31. When the aerosol-forming material 33 is in a paste or aerogel state, because the aerosol-forming material 33 is relatively thick, the heating main body 326 is difficult to freely sink in the aerosol-forming material 33 in a state of being not heated. In the direction Y1, an upper portion of the heating main body 326 is exposed to the aerosol-forming material 33, and a lower portion of the heating main body 326 may be or not in contact with the bottom of the container 31. In a heated state, the viscosity of the aerosol-forming material 33 is reduced, and the heating main body 326 may freely sink. Therefore, when an aerosol is initially formed, an upper end of the heating main body 326 is higher than a liquid level, and a lower end of the heating main body 326 is in contact with the bottom of the container 31. To be specific, in the direction Y1, the entire height of the heating main body 326 is greater than a liquid height. However, when the heating main body 326 heats, if the entire heating main body 326 floats on the liquid only, an amount of smoke is relatively small, and it is difficult to satisfy user requirements.

[0518] In this embodiment, the heating main body 326 has a rectangular cross section, and the heating main body 326 is a rectangular sheet formed by extending a rectangular plane along an axial direction of the container 31. The heating element 32 may further include at least one leg 327 disposed at a lower end (an end away from the opening 311 in the longitudinal direction Y1) of the heating main body 326. The leg 327 is sheet-like and perpendicular to the axial direction of the container 31, which assists in placing the heating element 32 upright in the container 31, so that the heating element 32 can be in a standing state all the time under a magnetic field force. In addition, the leg 327 further assists in thoroughly heating the aerosol-forming material 33 at the bottom of the container 31, thereby reducing residues and achieving a high utilization rate. In addition, there is a magnetic convergence effect, thereby improving the atomization efficiency.

[0519] It is set that the transverse direction Y2 is a direction parallel to a short side of the cross section of the heating main body 326 and the transverse direction Y3 is a direction parallel to a long side of the cross section of the heating main body 326. In this embodiment, there are two legs 327. The two legs 327 are respectively disposed at two opposite sides of the heating main body 326 in the transverse direction Y2. In some embodiments, a total cross-sectional area of the two legs 327 occupies 20% or more than 20% of a cross-sectional area of a lower end of the accommodating cavity 310 (i.e. an end in which the legs 327 are accommodated, or an end away from the opening 311 in the longitudinal direction Y1), and is smaller than a cross-sectional area of a lower end of the accommodating cavity 310. This is beneficial to thoroughly heat the aerosol-forming material 33 at the bottom of the container 31, without being in contact with the side wall of the accommodating cavity 310 for a long time, thereby improving the atomization efficiency.

[0520] In some embodiments, a sealing film 351, such as an aluminum foil, may be further disposed at the opening 311 of the container 31. The sealing film 351 is configured to seal the opening 311, thereby preventing the aerosol-forming material 33 in the container 31 from flowing out, preventing external impurities from entering the container 31, and ensuring cleanness inside the container 31. During use, the sealing film 351 may be first torn off, to expose the opening 311. In other embodiments, the sealing film 351 may alternatively be pierced to expose the opening 311.

[0521] As shown in FIG. 80a and FIG. 80b, the heating element 32 may further include a heating layer 326a and a soaking layer 326b disposed on an outer surface of the heating layer 326a. The heating layer 326a includes a sensor material for generating heat in a magnetic field, for example, a ferromagnetic material. The thickness of the heating layer 326a may be 0.05 mm to 0.5 mm (including two end values), and is preferably 0.2 mm to 0.35 mm (including two end values). The soaking layer 326b has a thermal conductivity lower than that of the heating layer 326a. In some embodiments, the thermal conductivity of the soaking layer 326b is less than or equal to 10 W / m·K, preferably less than or equal to 3 W / m·K, facilitating even distribution of heat in the heating element 32. The soaking layer 326b may be made of a low thermal conduction non-metal material, such as glass enamel, ceramics, silicon carbide, silicon nitride, or a Teflon coating, and is preferably glass enamel. The thickness of the soaking layer 326b may be 5 um to 50 um (including two end values), and is preferably 10 um to 30 um (including two end values).

[0522] In an implementation shown in FIG. 80a, the soaking layer 326b is dense and smooth, and can effectively reduce the surface carbon deposition of the heating element 32. In an implementation shown in FIG. 80b, the soaking layer 326b is superficially porous, and can adsorb and conduct a liquid medium through the wetting and capillary effect of a porous micro-pore structure, thereby reducing dry heating and increasing the amount of smoke.

[0523] The heating element 32 may alternatively be bare magnetic. To be specific, the heating element 32 has only the heating layer 326a, and at least a part of the sensor material of the heating element 32 is exposed.

[0524] FIG. 81 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating main body 326 of the heating element 32 in this embodiment is has an arc-shaped cross section, and the heating main body 326 is an arc sheet formed by extending an arc surface along an axial direction of the container 31.

[0525] FIG. 82 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating main body 326 of the heating element 32 in this embodiment has a swirl (or helical) cross section. The heating element 32 having a swirl structure has a larger contact area between the heating element 32 and the aerosol-forming material 33, so that a large amount of smoke can be generated, and the aerosol-forming material 33 can be rapidly atomized.

[0526] Specifically, the heating main body 326 includes a plurality of ring-shaped unit sheets 3261, and a clearance space 3260 is formed between every two adjacent unit sheets 3261. The shape of each unit sheet 3261 includes, but is not limited to, a circular ring, an elliptic ring, a triangular ring, or a square ring.

[0527] The size of the clearance space 3260 is related to the viscosity of the aerosol-forming material 33. A lower viscosity of the aerosol-forming material 33 indicates a smaller clearance space 3260. A higher viscosity indicates a larger clearance space 3260, thereby effectively preventing a large-particle exploding liquid. In some embodiments, the size of the clearance space 3260 may be greater than 0 and less than or equal to 5 mm, and is preferably 0.2 mm to 2 mm (including two end values).

[0528] The size of the clearance space 3260 is relatively small. During heating, the aerosol-forming material 33 in the clearance space 3260 can boil and rush up by a distance, so that the aerosol-forming material 33 continuously flushes a wall surface of the heating element 32, thereby increasing a contact area between the heating element 32 and the aerosol-forming material 33, increasing the amount of smoke, and reducing poor inhaling feeling caused by dry heating. In addition, strong convective heat transfer can be formed between every two adjacent unit sheets 3261, so as to rapidly atomize the aerosol-forming material 33 in the clearance space 3260.

[0529] In some embodiments, the surface of the heating element 32 further has a particular degree of roughness, so that the aerosol-forming material 33 rushing up can naturally flow down after remaining on the surface of the heating element 32 for a period of time, thereby reducing dry heating and increasing the amount of smoke. However, it is not proper for the aerosol-forming material 33 to remain on the surface of the heating element 32 for a long time, and otherwise, carbon deposition is easily caused. In some embodiments, the surface roughness of the heating element 32 may range from Ra0.05 to Ra25 (including two end values), preferably, from Ra0.05 to Ra6.3 (including two end values). When the heating element 32 is provided with a soaking layer 326b, the surface roughness of the soaking layer 326b may range from Ra0.05 to Ra25 (including two end values), preferably from Ra0.05 to Ra6.3 (including two end values).

[0530] The surface of the heating element 32 further has a lyophilic property (including hydrophilia and / or lipophilicity), so that the aerosol-forming material 33 can rise along the surface of the heating element 32. A liquid level of the aerosol-forming material 33 in the clearance space 3260 is raised by a distance due to surface tension, thereby increasing a contact area between the aerosol-forming material 33 and the heating element 32, and improving the atomization efficiency and the amount of smoke.

[0531] In embodiments shown in FIG. 83 and FIG. 84, the heating main body 326 of the heating element 32 has an S-shaped or S-like cross section. The heating element 32 having an S-shaped or S-like structure also enables the heating element 32 to have a larger contact area with the aerosol-forming material 33, thereby generating a larger amount of smoke and achieving a higher atomization speed.

[0532] Specifically, the heating main body 326 includes a plurality of unit sheets 3261 spaced apart in the transverse direction Y3 and a connection sheet 3262 connected between every two adjacent unit sheets 3261. A clearance space 3260 is formed between every two adjacent unit sheets 3261. The size of the clearance space 3260 is relatively small. During heating, the aerosol-forming material 33 in the clearance space 3260 can boil and rush up by a distance, thereby increasing a contact area between the heating element 32 and the aerosol-forming material 33, increasing the amount of smoke, and reducing poor inhaling feeling caused by dry heating.

[0533] The size of the clearance space 3260 is related to the viscosity of the aerosol-forming material 33. A lower viscosity of the aerosol-forming material 33 indicates a smaller clearance space 3260. A higher viscosity indicates a larger clearance space 3260, thereby effectively preventing a large-particle exploding liquid. In some embodiments, the size of the clearance space 3260 may be less than or equal to 5 mm, and is preferably 0.2 mm to 2 mm (including two end values).

[0534] In an embodiment shown in FIG. 83, the unit sheets 3261 are parallel to each other, so that the size of the clearance space 3260 keeps unchanged in the transverse direction Y2.

[0535] In an embodiment shown in FIG. 84, every two adjacent unit sheets 3261 are disposed at an angle, so that the size of the clearance space 3260 is gradually increased or reduced in the transverse direction Y2.

[0536] It may be understood that in other embodiments, every two adjacent unit sheets 3261 may alternatively be directly connected to each other.

[0537] FIG. 85 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating main body 326 of the heating element 32 in this embodiment is has a major arc-shaped cross section, and the heating main body 326 is an arc sheet formed by extending a major arc plane along an axial direction of the container 31. The heating main body 326 having a major arc-shaped cross section may be better disposed upright in the container 31, so that a lower end of the heating main body 326 does not need to be provided with a leg 327.

[0538] An upper end of the heating main body 326 is open, to avoid dry heating during a heating process. A bottom wall may be disposed at a lower end of the heating main body 326 to cover an opening at a lower end thereof. The bottom wall enables the heating main body 326 to be better disposed upright in the container 31, and thoroughly heats the aerosol-forming material 33 at the bottom of the container 31, thereby reducing residues and achieving a high utilization rate. In addition, there is a magnetic convergence effect, thereby improving the atomization efficiency.

[0539] FIG. 86 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment has a twist shape and may be formed by twisting one or more heating substrates into a twist shape. Specifically, in this embodiment, the heating element 32 is formed by twisting a rectangular sheet-like heating substrate into a twist shape.

[0540] FIG. 87 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment includes a sheet-like heating main body 326 and at least one branch portion 328 disposed on at least one side of the heating main body 326.

[0541] Specifically, in this embodiment, the heating main body 326 is in a shape of a rectangular sheet. There are a plurality of branch portions 328. The plurality of branch portions 328 are respectively symmetrically disposed on two sides of the thickness of the heating main body 326, so that the heating element 32 has a fish-bone like shape as a whole.

[0542] It may be understood that in other embodiments, the plurality of branch portions 328 may be respectively disposed on two opposite sides of the heating main body 326 in a staggered mode, or the plurality of branch portions 328 may be disposed on a same side of the heating main body 326.

[0543] FIG. 88 to FIG. 90 show an aerosol-forming product 30 according to some embodiments of the present disclosure, including a container 31, and a heating element 32 and an aerosol-forming material 33 disposed in the container 31.

[0544] The heating element 32 has at least two surfaces 3216. At least one clearance space 3217 is formed between the at least two surfaces 3216. The clearance space 3217 extends along a longitudinal direction Y1 of the heating element 32. The pair of surfaces 3216 are oppositely disposed in a transverse direction Y2 of the heating element 32. The longitudinal direction Y1 and the transverse direction Y2 are perpendicular to each other. When the heating element 32 is placed in the container 31 for use, the longitudinal direction Y1 of the heating element 32 is parallel to an axial direction of the container 31 and is approximately parallel to a direction of a magnetic field. In addition, the heating element 32 further has a transverse direction Y3 perpendicular to both the longitudinal direction Y1 and the transverse direction Y2.

[0545] At least one end of the clearance space 3217 in the longitudinal direction Y1 of the heating element 32 has a first opening 321a, and / or at least one end of the clearance space 3217 in the transverse direction Y3 of the heating element 32 has a second opening 321b, so that the clearance space 3217 is communicated with the accommodating cavity 310 via the first opening 321a and / or the second opening 321b.

[0546] Further, the at least two surfaces 3216 further have a lyophilic property (including hydrophilia and / or lipophilicity), so that the aerosol-forming material 33 can rise along the surfaces 3216, and the liquid level is concave. The liquid level of the aerosol-forming material 33 in the clearance space 3217 is raised by a distance due to surface tension. In this way, a contact area between the aerosol-forming material 33 and the surfaces 3216 can be increased, the atomization efficiency is higher, and the amount of smoke is larger.

[0547] In some embodiments, the at least two surfaces 3216 include at least one pair of oppositely disposed surfaces 3216. A distance between the two oppositely disposed surfaces 3216 is relatively short, so that strong convective heat transfer is formed between the two surfaces 3216, so as to rapidly atomize the aerosol-forming material 33 in the clearance space 3217.

[0548] The size of a distance d1 between the two oppositely disposed surfaces 3216 is related to the viscosity of the aerosol-forming material 33. A lower viscosity of the aerosol-forming material 33 indicates a smaller d1. A higher viscosity indicates a larger d1, thereby effectively preventing a large-particle exploding liquid in the clearance space 3217. In addition, the distance d1 between the two surfaces 3216 may remain unchanged in the longitudinal direction Y1, or may have different sizes in the longitudinal direction Y1. Herein, d1 refers to the distance between the two oppositely disposed surfaces 3216 in the transverse direction Y2. In some embodiments, the range of d1 may be 0<d1≤5 mm, preferably 0<d1≤2 mm. The range of an inner diameter d2 of the container 31 may be 3 mm≤d2≤8 mm, preferably 4 mm≤d2≤6 mm.

[0549] The shape of each surface 3216 is not limited. For example, the surface may include a flat surface, a curved surface (such as an arc surface), or a combination of a flat surface and a curved surface.

[0550] Specifically, in this embodiment, the heating element 32 may include two heating side walls 321 oppositely disposed in the transverse direction Y2 of the heating element 32. The two oppositely disposed surfaces 3216 are formed by opposite surfaces of the two heating side walls 321. In this embodiment, the two heating side walls 321 both have a planar sheet-like structure. To be specific, each surface of the heating side wall 321 is planar. In addition, the two heating side walls 321 are disposed parallel to each other, so that the distance d1 between the two surfaces 3216 keeps unchanged in the longitudinal direction Y1.

[0551] When the container 31 is filled with the aerosol-forming material 33, the lowest liquid level of the aerosol-forming material 33 may be lower than an upper edge 321c of the heating element 32, so that the heating element 32 is partially exposed to the aerosol-forming material 33, facilitating rapid smoke output.

[0552] When the aerosol-forming material 33 includes a paste, because the paste is mostly solid at a room temperature, a relative position relationship between the aerosol-forming material 33 and the heating element 32 may be determined after the aerosol-forming material 33 is heated to a particular temperature (for example, greater than or equal to 75° C. and less than a boiling point) and liquefied.

[0553] Because the surface of the heating element 32 has a lyophilic property, a liquid level L2 between the two heating side walls 321 is higher than a liquid level L1 between the heating side wall 321 and the container 31. In some embodiments, the range of a distance Δd between the upper edge 321c of the heating element 32 and the liquid level L1 may be 0<Δd≤10 mm, preferably 0<Δd≤5 mm.

[0554] In some embodiments, the heating element 32 and the inner wall surface of the container 31 are at least partially spaced apart, so that a part of the aerosol-forming material 33 can be further filled in the clearance 3210 formed between the heating element 32 and the inner wall surface of the container 31, thereby further increasing a contact area between the aerosol-forming material 33 and the heating element 32. The clearance space 3217 may be communicated with the clearance 3210 through the first opening 321a and / or the second opening 321b, so that the aerosol-forming material 33 can flow between the clearance space 3217 and the clearance 3210.

[0555] In some embodiments, the heating element 32 includes a middle portion 32b and an upper portion 32a and a lower portion 32c respectively located at two ends of the middle portion 32b in the longitudinal direction Y1. An effective cross-sectional area of the upper portion 32a and an effective cross-sectional area of the lower portion 32c are both greater than an effective cross-sectional area of the middle portion 32b, which is beneficial to convergence of magnetic fields relatively dispersed at two ends, thereby improving utilization of the magnetic field. In addition, a relatively strong magnetic field is formed in the middle portion 32b by means of magnetic conduction of the heating element 32, so that more magnetic field lines are cut per unit area in the cross section of the middle portion 32b, thereby improving a temperature increasing speed of the middle portion 32b, reducing a preheat time, and improving energy utilization.

[0556] Herein, the “effective cross-sectional area” refers to a cross-sectional area of a part for transmitting a magnetic flux line in the heating element 32. Shaded parts (i.e. parts having section lines) in FIG. 90a, FIG. 90b, and FIG. 90c are respectively effective cross-sectional areas of the upper portion 32a, the lower portion 32c, and the middle portion 32b. In some embodiments, the effective cross-sectional area of the middle portion 32b may be 10% to 30% (including two end values) of the effective cross-sectional area of the upper portion 32a or the lower portion 32c. The effective cross-sectional areas of the upper portion 32a and the lower portion 32c may be equal or not equal. In other embodiments, the effective cross-sectional area of only one of the upper portion 32a and the lower portion 32c may be greater than the effective cross-sectional area of the middle portion 32b.

[0557] With reference to FIG. 89, in some embodiments, at least one protrusion portion 3215 is formed by protruding a side of the upper portion 32a and the lower portion 32c of each heating side wall 321 away from the other heating side wall 321, to increase the effective cross-sectional areas of the upper portion 32a and the lower portion 32c. The protrusion portion 3215 may further reduce a contact area between the heating element 32 and the container 31, thereby reducing a friction force, and making vibration of the heating element 32 more smooth. In addition, a positioning effect may be achieved, to prevent from causing uneven temperature or carbonization of a medium on the container 31 and causing bad inhaling feeling due to a large-area contact between the heating side wall 321 and the container 31.

[0558] Specifically, in this embodiment, two protrusion portions 3215 are formed by protruding from the upper portion 32a of each heating side wall 321. The two protrusion portions 3215 have a sheet shape and are respectively located at two sides of the transverse direction Y3 of the heating side wall 321. Two protrusion portions 3215 are also formed by protruding from the lower portion 32c of each heating side wall 321. The two protrusion portions 3215 have a sheet shape and are respectively located at two sides of the transverse direction Y3 of the heating side wall 321. In other embodiments, the quantity of the protrusion portions 3215 is not limited. In addition, the effective cross-sectional area of the middle portion 32b may be reduced by forming an opening in the middle portion 32b of the heating side wall 321.

[0559] Further, in this embodiment, the clearance space 3217 has a second opening 321b at two ends of the transverse direction Y3 of the heating element 32, and the clearance space 3217 has a first opening 321a at a top end (an end close to the opening 311) of the longitudinal direction Y1 of the heating element 32. The heating element 32 further includes a heating bottom wall 322 connecting the two heating side walls 321. The heating bottom wall 322 has a sheet shape, and may be connected to bottom ends of the two heating side walls 321 in the longitudinal direction Y1 and be disposed opposite to the first opening 321a. On one hand, the heating element 32 can be disposed upright in the container 31, and on the other hand, the effective cross-sectional area of the bottom of the heating element 32 can be further increased, facilitating further convergence of the magnetic field. In addition, the heating bottom wall 322 further assists in thoroughly heating the aerosol-forming material 33 at the bottom of the container 31, thereby reducing residues and achieving a high utilization rate.

[0560] In an embodiment shown in FIG. 91, a porous body 329 may further be disposed in the clearance space 3217 between the two heating side walls 321. The material of the porous body 329 may include ceramics, glass, graphites, or wool, and is preferably ceramics. The porous body 329 is freely placed in the clearance space 3217. The aerosol-forming material 33 is absorbed by the porous body 329 due to enhanced thermal fluidity. There is strong convective heat transfer between the two heating side walls 321, so as to rapidly atomize a medium absorbed by the porous body 329, increase the amount of smoke, and improve the inhaling feeling. In this embodiment, the porous body 329 is a porous sheet. The thickness of the porous sheet may be 0.5 mm to 3 mm (including two end values), and is preferably 0.8 mm to 1.5 mm (including two end values). In other embodiments, the form of the porous body 329 may include one or a combination of filament, particle, sheet, and the like.

[0561] In an embodiment shown in FIG. 92, the two heating side walls 321 are disposed at an angle, and the two surfaces 3216 of the two heating side walls 321 are planar and are disposed at an angle E relative to each other. In some embodiments, the range of the angle E may be 0<E≤30°. In addition, the bottom ends of the two heating side walls 321 are connected by using a heating bottom wall 322, so that a distance between the two surfaces 3216 is gradually increased from bottom to top. In addition, in this embodiment, only the upper portions of the two heating side walls 321 are provided with protrusion portions 3215, so as to increase the effective cross-sectional areas of the upper portions. In other embodiments, the distance between the two surfaces 3216 may be gradually reduced from bottom to top, and / or the protrusion portions 3215 may be disposed at the upper and lower portions of the two heating side walls 321.

[0562] FIG. 93 shows a heating element 32 according to some embodiments of the present disclosure. Compared with the embodiment shown in FIG. 92, in this embodiment, the bottom ends of the two heating side walls 321 are directly connected together. To be specific, a minimum distance between the two surfaces 3216 is zero, and the distance is gradually increased from bottom to top.

[0563] FIG. 94 shows a heating element 32 according to some embodiments of the present disclosure. Compared with the embodiment shown in FIG. 89, in this embodiment, the two heating side walls 321 each have an arc-shaped sheet shape. To be specific, two opposite surfaces of each heating side wall 321 in the transverse direction Y2 are arc surfaces. The two surfaces 3216 of the two heating side walls 321 are arc surfaces and axes thereof are parallel to each other. The bottom ends of the two heating side walls 321 are connected by using a sheet-like heating bottom wall 322. In addition, two peripheral sides of the upper portion and the lower portion of each heating side wall 321 extend outward along a peripheral direction to form a protrusion portion 3215, so as to increase the effective cross-sectional areas of the upper portion and the lower portion of the heating element 32.

[0564] In another implementation, the structure of the heating element 32 may be deformed. For example, axes of the two heating side walls 321 may be disposed at an angle. And / or, the bottom ends of two heating side walls 321 may be directly connected together. And / or, only the upper portion or the lower portion of the heating element 32 is provided with a protrusion portion 3215. And / or, a through hole or a through groove is provided in the heating side wall 321 in the middle of the heating element 32.

[0565] FIG. 95 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the embodiment shown in FIG. 89 lies in that in this embodiment, the heating element 32 includes two heating side walls 321 oppositely disposed in the transverse direction Y2 of the heating element 32, and at least one connection portion 3218 that is connected to the two heating side walls 321 and covers a part of the second opening 321b.

[0566] Similar to the embodiment shown in FIG. 89, the heating element 32 in this embodiment also includes a middle portion 32b and an upper portion 32a and a lower portion 32c respectively located at two ends of the middle portion 32b in the longitudinal direction Y1. In this embodiment, the upper portion 32a and the lower portion 32c of the heating element 32 are respectively provided with two connection portions 3218 oppositely disposed in the transverse direction Y3, so that the effective cross-sectional areas of the upper portion 32a and the lower portion 32c can be increased.

[0567] In this embodiment, the two heating side walls 321 have a planar sheet shape, and the two connection portions 3218 have an arc-shaped sheet shape, so that the upper portion 32a and the lower portion 32c have a runway-shaped cross section. In other embodiments, the heating side walls 321 and the connection portions 3218 may alternatively have other shapes. For example, the heating side walls 321 have an arc-shaped sheet shape, and / or, the connection portions 3218 have a planar sheet shape. In some other embodiments, the connection portion 3218 may alternatively be disposed only at the upper portion 32a or the lower portion 32c of the heating element 32.

[0568] In some embodiments, the upper portion 32a and the lower portion 32c of the heating element 32 may further be provided with protrusion portions 3215 protruding out of the clearance space 3217, thereby further increasing the effective cross-sectional areas of the upper portion 32a and the lower portion 32c. Specifically, in this embodiment, two ends of the upper portion 32a and the lower portion 32c of each heating side wall 321 in the transverse direction Y3 are respectively provided with a sheet-like protrusion portion 3215 protruding away from the other heating side wall 321. The protrusion portion 3215 further reduces a contact friction force between the heating element 32 and the container 31, thereby making vibration of the heating element 32 more smooth. In addition, a positioning effect may be achieved, to prevent from causing carbonization of a medium on the container 31 and causing bad inhaling feeling due to the contact between the heating side wall 321 and the container 31.

[0569] In addition, in this embodiment, the clearance space 3217 has a first opening 321a at two ends of the longitudinal direction Y1 of the heating element 32. In other embodiments, the lower ends of the two heating side walls 321 may also be provided with a heating bottom wall 322, to shield a part of the first openings 321a at the lower ends.

[0570] FIG. 96 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the embodiment shown in FIG. 89 lies in that in this embodiment, the heating element 32 includes four heating side walls 321 spaced apart in the peripheral direction. The four heating side walls 321 define a clearance space 3217.

[0571] Specifically, in this embodiment, each heating side wall 321 has a planar sheet shape, and the four heating side walls 321 are evenly spaced apart in the peripheral direction of the heating element 32, so as to form two pairs of oppositely disposed surfaces 3216. In other embodiments, each heating side wall 321 may alternatively have another shape such as an arc-shaped sheet.

[0572] In some embodiments, the heating element 32 may further include a heating bottom wall 322. The heating bottom wall 322 covers a lower opening of the clearance space 3217. The four heating side walls 321 may extend upward from a peripheral edge of the heating bottom wall 322. In other embodiments, the heating element 32 may alternatively not include the heating bottom wall 322.

[0573] FIG. 97 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the embodiment shown in FIG. 96 lies in that in this embodiment, the heating element 32 includes three heating side walls 321 evenly spaced apart in the peripheral direction, so as to form three surfaces 3216 evenly spaced apart in the peripheral direction of the heating element 32. A clearance space 3217 is defined in the three surfaces 3216.

[0574] FIG. 98 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 includes a plurality of cylindrical heating side walls 321 spaced apart in the peripheral direction of the heating element 32 and at least one connection portion 3218 connecting the plurality of heating side walls 321. A heating cavity 320 is defined in the plurality of heating side walls 321. Each heating side wall 321 may have a solid column shape or a hollow column shape.

[0575] In this embodiment, upper and lower ends of the heating cavity 320 are open. There are two connection portions 3218. The two connection portions 3218 are both annular and are respectively located at two axial ends of the plurality of heating side walls 321, which assists in improving a magnetic convergence effect at the two ends. In other embodiments, there may alternatively be one or more connection portions 3218. In addition, the connection portion 3218 may alternatively be disposed between two ends of the heating side wall 321.

[0576] FIG. 99 shows a heating element 32 according to some embodiments of the present disclosure. Different from the foregoing embodiments, upper and lower ends of the heating cavity 320 in this embodiment are sealed. Specifically, the two connection portions 3218 are both in a sheet shape and are respectively disposed at the upper and lower ends of the heating cavity 320, thereby sealing the upper and lower ends of the heating cavity 320.

[0577] FIG. 100 and FIG. 101 show a heating element 32 according to some embodiments of the present disclosure. The heating element 32 has a cellular shape, and has a plurality of through holes 320a formed through. Each through hole 320a extends through two axial ends of the heating element 32, and has functions of circulating airflow and accommodating the aerosol-forming material 33. Preferably, the through hole 320a is a capillary through hole having a capillarity force or a weak capillarity force. In other embodiments, the cross-sectional size of the through hole 320a may be relatively large, so as not to have a capillarity force.

[0578] FIG. 102 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment is in a shape of a hemispherical pot with a heating cavity 320 formed therein. An aerosol-forming material 33 may be accommodated in the heating cavity 320.

[0579] FIG. 103 shows a heating element 32 according to some embodiments of the present disclosure. In this embodiment, the heating element 32 has a cylindrical shape with an open upper end, and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at a lower end of the heating side wall 321. A plurality of through holes 3220 are formed on the heating side wall 321. The plurality of through holes 3220 may be evenly spaced apart in an axial direction and / or a peripheral direction of the heating side wall 321. By providing the through holes 3220, an exploding liquid phenomenon that occurs after the aerosol-forming material 33 in the heating element 32 is heated can be effectively reduced, the surface of the heating element 32 can be more easily plated with an enamel layer in a process of enameling the heating element 32, thereby ensuring that the heating element 32 is uniformly plated with the enamel layer.

[0580] In other embodiments, the plurality of through holes 3220 may alternatively be formed on the heating bottom wall 322, or may be formed on both the heating side wall 321 and the heating bottom wall 322.

[0581] FIG. 104 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment has a shape of a tube with two open ends.

[0582] FIG. 105 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment includes a heating side wall 321 having a step-like shape. Specifically, the heating side wall 321 includes a first side wall 3211, a second side wall 3212, and a third side wall 3213 that are disposed in sequence from bottom to top along an axial direction. Inner diameters and outer diameters of the first side wall 3211, the second side wall 3212, and the third side wall 3213 are increased in sequence. In other embodiments, the shape of the heating side wall 321 may be randomly deformed. For example, the inner diameters and the outer diameters of the first side wall 3211, the second side wall 3212, and the third side wall 3213 may be gradually reduced. Alternatively, the inner diameter and the outer diameter of the second side wall 3212 are respectively greater than the inner diameters and the outer diameters of the first side wall 3211 and the third side wall 3213.

[0583] The lower end of the heating element 32 may have a heating bottom wall 322, or may not have a heating bottom wall 322.

[0584] FIG. 106 shows a heating element 32 according to some embodiments of the present disclosure. In this embodiment, the heating element 32 has a conical cylindrical shape with an open upper end, and includes a conical tubular heating side wall 321 and a heating bottom wall 322 disposed at a lower end of the heating side wall 321. Both an inner diameter and an outer diameter of the heating side wall 321 are gradually increased from bottom to top. In other embodiments, the inner diameter and the outer diameter of the heating side wall 321 may be gradually reduced from the bottom to the top.

[0585] FIG. 107 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment has a shape of a conical tube with two open ends.

[0586] In some of the foregoing embodiments, the position of the heating element 32 in the container 31 may be relatively fixed or substantially fixed. For example, a limiting member is disposed to fix the heating element 32 in the container 31, or a protrusion is formed on the heating element 32 and / or the container 31 to position the heating element 32 in the container 31, so as to avoid sway of the heating element 32 in the container 31 during transportation or heating. In some embodiments, the heating element 32 may alternatively have a particular active space in the container 31. In this way, during a heating process, the viscosity of the aerosol-forming material 33 is reduced, and bubbles and magnetic force generated by the aerosol-forming material 33 can push the heating element 32 to move in the container 31, to implement a function of stirring the aerosol-forming material 33, so that the bubbles are rapidly collapsed to release a large amount of smoke, thereby implementing rapid atomization by using relatively small power. In addition, because the heating element 32 is not fixed in the container 31 and the heating element 32 may be taken out from the container 31, the heating element 32 may alternatively be used as a disposable consumable, thereby avoiding a problem of cleaning the heating element 32. In addition, the structure of the heating element 32 is simple and cheap, and replacement costs are relatively low. The entire container 31 may alternatively be replaced, thereby avoiding a problem of cleaning the container 31.

[0587] FIG. 108 and FIG. 109 show an aerosol-forming product 30 according to some embodiments of the present disclosure, including a container 31, and a heating element 32 and an aerosol-forming material 33 disposed in the container 31.

[0588] In this embodiment, the heating element 32 is in a shape of a container, a heating cavity 320 is formed therein, and an aerosol-forming material 33 may be disposed in the heating cavity 320. Specifically, the heating element 32 includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at an axial end of the heating side wall 321. In other embodiments, the heating side wall 321 may alternatively have or approximately have another tube shape such as an elliptic tube shape, a runway-shaped tube shape, a square tube shape, or a polygonal tube shape.

[0589] In addition, in this embodiment, the heating element 32 has an even or approximately even thickness. Specifically, the heating side wall 321 and the heating bottom wall 322 have the same or approximately the same thickness. In other embodiments, the heating side wall 321 and / or the heating bottom wall 322 may alternatively have an uneven wall thickness.

[0590] A clearance 3210 is formed between an outer wall surface (a surface radially away from the heating cavity 320) of the heating element 32 and an inner wall surface (a surface radially close to the heating cavity 320) of the container 31, so that the heating element 32 has a particular active space in the container 31, and a large-area contact between the outer wall surface of the heating element 32 and the inner wall surface of the container 31 is reduced. The heating element 32 is further provided with a through hole 3220. During heating, the aerosol-forming material 33 in the heating element 32 can flow to the clearance 3210 through the through hole 3220.

[0591] According to a first aspect, the aerosol-forming material 33 flowing into the clearance 3210 can be in contact with the outer wall surface of the heating element 32, so that a contact area between the aerosol-forming material 33 and the heating element 32 is increased, thereby increasing the amount of smoke. In addition, because there is a relatively small quantity of the aerosol-forming material 33 in the clearance 3210, the temperature rises more rapidly, facilitating rapid smoke output. According to a second aspect, as shown in FIG. 109, a relatively small clearance 3210 may enable the aerosol-forming material 33 in the clearance 3210 to boil and rush up by a distance, so that the aerosol-forming material 33 continuously flushes a wall surface of the heating element 32, thereby increasing a contact area between the outer wall surface of the heating element 32 and the aerosol-forming material 33, increasing the amount of smoke, and reducing poor inhaling feeling caused by dry heating. According to a third aspect, as shown in FIG. 110, bubbles 330 generated in the heating process of the aerosol-forming material 33 in the clearance 3210 can push the heating element 32 to move in the container 31, to implement a function of stirring the aerosol-forming material 33, so that the bubbles 330 are rapidly burst to release a large amount of smoke by stirring, thereby implementing rapid atomization by using relatively small power. According to a fourth aspect, by providing the through holes 3220, an exploding liquid phenomenon that occurs after the aerosol-forming material 33 in the heating element 32 is heated can be reduced.

[0592] The surface of the heating side wall 321 of the heating element 32 has a particular degree of roughness, so that the aerosol-forming material 33 rushing up can naturally flow down after remaining on the surface of the heating side wall 321 for a period of time, thereby reducing dry heating and increasing the amount of smoke. However, it is not proper for the aerosol-forming material 33 to remain on the surface of the heating side wall 321 for a long time, and otherwise, carbon deposition is easily caused. In some embodiments, the surface roughness of the heating side wall 321 may range from Ra0.05 to Ra25 (including two end values), preferably, from Ra0.05 to Ra6.3 (including two end values). When the heating element 32 is provided with a soaking layer 326b, the surface roughness of the soaking layer 326b may range from Ra0.05 to Ra25 (including two end values), preferably from Ra0.05 to Ra6.3 (including two end values).

[0593] There may be one or more through holes 3220. The shape of the through hole 3220 may be any regular or irregular shape such as a circle, an ellipse, a triangle, or a polygon, and is preferably a circle or an ellipse. The through hole 3220 may be provided in the heating side wall 321 and / or the heating bottom wall 322. As shown in FIG. 108, in this embodiment, the through hole 3220 is circular and is provided in the heating bottom wall 322. A hole diameter d5 of the through hole 3220 may be 0.5 mm to 3 mm (including two end values), and is preferably 0.8 mm to 1.5 mm (including two end values).

[0594] The size of the clearance 3210 is related to the viscosity of the aerosol-forming material 33. In some embodiments, a size d4 of the clearance 3210 may be 0<d4≤5 mm, preferably 0.2 mm≤d4≤2 mm. An outer diameter d3 of the heating element 32 may be 2.5 mm to 6 mm (including two end values), and is preferably 3.5 mm to 5 mm (including two end values). An inner diameter d2 of the container 31 may be 4 mm to 10 mm (including two end values), and is preferably 5.5 mm to 8 mm (including two end values). Herein, the size d4 of the clearance 3210 refers to a distance between the outer wall surface of the heating element 32 and the inner wall surface of the container 31 when the heating element 32 and the container 31 are coaxially disposed.

[0595] FIG. 111 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that in this embodiment, a through hole 3220 is provided in the heating side wall 321. Preferably, the through hole 3220 is provided at a position of the heating side wall 321 close to the heating bottom wall 322, so that in most processes of being consumed because of heating, the aerosol-forming material 33 can flow out through the through hole 3220. In some embodiments, a distance h between a center line of the through hole 3220 and the bottom surface of the heating element 32 may be less than or equal to 6 mm, preferably 0<h≤3 mm.

[0596] FIG. 112 and FIG. 113 show a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that an inner wall surface of the heating side wall 321 of the heating element 32 in this embodiment is a smooth surface, and an outer wall surface of the heating side wall 321 is convex-concave, so that the wall thickness of the heating side wall 321 is uneven. On one hand, the convex-concave outer wall surface can reduce time in which the aerosol-forming material 33 remains on the outer wall surface of the heating side wall 321, thereby reducing dry heating and improving the amount of smoke. On the other hand, the contact area between the container 31 and the heating element 32 when being pushed by the bubbles to move can be reduced, facilitating to reduce the amount of heat transferred by the heating element 32 to the container 31.

[0597] Specifically, in this embodiment, the heating side wall 321 may include a tubular body 321e and a plurality of ribs 321f extending outward from an outer wall of the tubular body 321e. The tubular body 321e has a circular tube shape, the plurality of ribs 321f are evenly spaced apart in a peripheral direction of the tubular body 321e, and each rib 321f extends vertically downward from an upper end surface of the tubular body 321e to a lower end surface. The ribs 321f extend along a vertical direction, facilitating flow of the aerosol-forming material 33. In other embodiments, the tubular body 321e alternatively has another shape such as an elliptic tube, a square tube, or a polygonal tube.

[0598] A plurality of convex surfaces 321g are formed on outer wall surfaces of the plurality of ribs 321f, and a plurality of convex surfaces 321h are formed on an outer wall surface of a part of the tubular body 321e located between every two adjacent ribs 321f. The plurality of convex surfaces 321g and the plurality of convex surfaces 321h are alternately distributed one by one in the peripheral direction of the heating side wall 321, and the convex surfaces 321g are closer to the inner wall surface of the container 31 in a radial direction than the convex surfaces 321h are. When the heating element 32 is pushed to move by the bubbles, the convex surfaces 321g of the heating element 32 are in contact with the inner wall surface of the container 31, but the convex surfaces 321h are not in contact with the inner wall surface of the container 31, thereby greatly reducing a contact area with the container 31.

[0599] FIG. 114 and FIG. 115 show a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating side wall 321 of the heating element 32 in this embodiment has a special-shaped tube shape, and an inner wall surface and an outer wall surface of the heating side wall 321 are both convex-concave, so that the wall thickness of the heating side wall 321 is even or approximately even.

[0600] Specifically, in this embodiment, the heating side wall 321 includes a plurality of convex portions 321j and a plurality of convex portions 321k that are alternately distributed in a peripheral direction. The plurality of convex portions 321j and the plurality of convex portions 321k are connected to form the heating side wall 321 having an even or approximately even wall thickness. Outer wall surfaces of the plurality of convex portions 321j form a plurality of convex surfaces 321g, and outer wall surfaces of the plurality of convex portions 321k form a plurality of concave surfaces 321h. The plurality of convex surfaces 321g and the plurality of convex surfaces 321h are alternately distributed one by one in the peripheral direction of the heating side wall 321, and the convex surfaces 321g are closer to the inner wall surface of the container 31 in a radial direction than the convex surfaces 321h are. When the heating element 32 is pushed to move by the bubbles, the convex surfaces 321g of the heating element 32 are in contact with the inner wall surface of the container 31, but the convex surfaces 321h are not in contact with the inner wall surface of the container 31, thereby greatly reducing a contact area with the container 31.

[0601] More specifically, in this embodiment, connection lines of cross-sectional contours of the plurality of convex portions 321j form a tubular structure. Every two convex portions 321j are connected to each other by using one convex portion 321k, and the convex portion 321k has an arc shape and is recessed into the heating cavity 320.

[0602] FIG. 116 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that a plurality of positioning legs 321m are formed by protruding outward from the heating side wall 321 of the heating element 32 in this embodiment. The plurality of positioning legs 321m may be spaced apart in an axial direction and / or a peripheral direction of the heating side wall 321. Specifically, in this embodiment, the plurality of positioning legs 321m may be integrally formed by extending outward from the upper end of the heating side wall 321, and may be evenly spaced apart in the peripheral direction of the heating side wall 321, which is beneficial to even stressing, and is beneficial to convergence of relatively dispersed magnetic fields at the upper end. The plurality of positioning legs 321m can prevent the heating side wall 321 from being in contact with the container 31 for a long time, thereby greatly reducing the amount of heat transferred by the heating element 32 to the container 31, and preventing from causing carbonization of a medium on the container 31 and causing bad inhaling feeling due to an over-high temperature of the container 31. Preferably, the quantity of the positioning legs 321m may be 3 to 8, to facilitate processing and manufacturing. In other embodiments, only one positioning leg 321m may alternatively be provided. In some other embodiments, the positioning leg 321m may alternatively be disposed at any other position such as the lower end or the middle portion of the heating side wall 321.

[0603] FIG. 117 and FIG. 118 show an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the aerosol-forming product 30 in this embodiment further includes a limiting member 34 sleeved on the heating element 32. The limiting member 34 includes at least one limiting leg 345. The at least one limiting leg 345 may prevent the heating side wall 321 from being in contact with the container 31 for a long time, thereby greatly reducing the amount of heat transferred by the heating element 32 to the outside.

[0604] Specifically, in this embodiment, the limiting member 34 is sleeved at the upper end of the heating element 32, and may include an annular body 346 sleeved around the heating side wall 321, at least one limiting leg 345 protruding outward from the annular body 346, and at least one inner flange 347 protruding inward from the annular body 346. The at least one inner flange 347 may abut against an upper end surface of the heating side wall 321, to implement axial positioning of the limiting member 34.

[0605] Preferably, there are a plurality of limiting legs 345 and a plurality of inner flanges 347. The plurality of limiting legs 345 and the plurality of inner flanges 347 are evenly spaced apart in a peripheral direction of the annular body 346.

[0606] In one embodiment, the limiting member 34 implements limiting by contact between the plurality of limiting legs 345 and the container 31. An inner diameter of the annular body 346 may be greater than an outer diameter of the heating side wall 321, so that a clearance exists between an inner wall surface of the annular body 346 and an outer wall surface of the heating side wall 321, and the heating element 32 may move within a range restricted by the annular body 346.

[0607] In another embodiment, there may be no clearance between the annular body 346 and the heating side wall 321. For example, the annular body 346 and the heating side wall 321 are riveted and f...

[0017] The entire disclosure of the foregoing applications is hereby incorporated by reference herein.FIELD

[0018] The present disclosure relates to the technical field of atomization, and specifically, to an aerosol-forming product and an aerosol-forming system.BACKGROUND

[0019] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Because the aerosol may be absorbed by a human body through a respiratory system, a new alternative absorption method is provided for users. An atomization device refers to a device that forms an aerosol by heating or ultrasonically processing a stored atomizable medium. The atomizable medium includes a liquid, gel, paste, or solid aerosol-forming material. These mediums may be atomized to deliver an inhalable aerosol to a user, for replacing a conventional product form and absorption mode.

[0020] Generally, the user needs to voluntarily fill the aerosol-forming material before the aerosol-forming material is used for the first time or after the aerosol-forming material is used. However, the filling amount and quality of the aerosol-forming material may be uncontrollable, or other atomized particles may be carried in a filling process, thereby affecting user experience.SUMMARY

[0021] In an embodiment, the present invention provides an aerosol-forming product, comprising: a container, an accommodating cavity configured to accommodate an aerosol-forming material being formed in the container, wherein the aerosol-forming product is configured to generate heat in a magnetic field to heat the aerosol-forming material.BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present disclosure is not limited to the specific embodiments disclosed below.

[0196] In the descriptions of the present disclosure, it should be understood that, orientation or position relationships indicated by terms such as “longitudinal”, “transverse”, “upper”, “lower”, “top”, “bottom”, “inner”, and “outer” are orientation or position relationship shown based on the accompanying drawings or orientation or position relationship that the product of the present disclosure is usually placed in use, and are merely used for describing the present disclosure and simplifying the description, rather than indicating or implying that the mentioned device or element should have a particular orientation or be constructed and operated in a particular orientation, and therefore, should not be construed as a limitation to the present disclosure.

[0197] In addition, terms “first” and “second” are used merely for the purpose of description, and shall not be construed as indicating or implying relative importance or implying a quantity of indicated technical features. Therefore, a feature restricted by “first” or “second” may explicitly indicate or implicitly include at least one of such features. In the descriptions of the present disclosure, unless explicitly specified, “plurality of” means at least two, for example, two or three.

[0198] In the present disclosure, unless otherwise explicitly specified and limited, the terms “mount”, “connect”, “connection”, and “fix” should be understood in a broad sense. For example, a connection may be a fixed connection, a detachable connection, or an integral connection. Alternatively, the connection may be a mechanical connection or an electrical connection. Alternatively, the connection may be a direct connection, an indirect connection through an intermediary, or internal communication between two elements or mutual action relationship between two elements, unless otherwise specified explicitly. A person of ordinary skill in the art may understand the specific meanings of the foregoing terms in the present disclosure according to specific situations.

[0199] In the present disclosure, unless otherwise explicitly specified and limited, the first feature being located “on” or “beneath” the second feature may be the first feature being in a direct contact with the second feature, or the first feature being in an indirect contact with the second feature through an intermediary. In addition, the first feature being “above” the second feature may be that the first feature is right above the second feature or at an inclined top of the second feature, or may merely indicate that a horizontal position of the first feature is higher than that of the second feature. The first feature being “below” the second feature may be that the first feature is right below the second feature or at an inclined bottom of the second feature, or may merely indicate that the horizontal position of the first feature is lower than that of the second feature.

[0200] FIG. 1 to FIG. 4 show an aerosol-forming system 100 according to some embodiments of the present disclosure. The system includes an atomization device 40 and an aerosol-forming product 30 at least partially adapted to the atomization device 40. The atomization device 40 is configured to heat an aerosol-forming material 33 to form an aerosol for use by a user. The aerosol-forming material 33 is accommodated in the aerosol-forming product 30. A heating mode of the aerosol-forming system 100 may be one or a combination of heat conduction, electromagnetism, infrared radiation, ultrasonic waves, microwaves, and plasma. As used herein, the term “aerosol-forming material” indicates a material that can release a volatile compound to form an aerosol after being heated. The aerosol-forming material 33 includes, but is not limited to, a material for medical, health maintenance, health, or beauty purposes. The aerosol-forming material 33 may include a solid, a liquid, a paste, or a gel, or may include any combination of two or more of the solid, the liquid, the paste, and the gel.

[0201] The aerosol-forming material 33 may include one or more of nicotine, a nicotine base, a nicotine salt, a nicotine derivative, and a nicotine analog. The nicotine salt may be selected from the list consisting of: nicotine citrate, nicotine lactate, nicotine pyruvate, nicotine bitartrate, nicotine pectate, nicotine alginate, and nicotine salicylate.

[0202] The aerosol-forming material 33 may include an aerosol-forming agent. The term “aerosol-forming agent” is used for describing any suitable known compound or compound mixture that helps to promote and stabilize formation of an aerosol during use, and is substantially resistant to thermal degradation at a working temperature of the aerosol-forming product 30. Suitable aerosol-forming agents include, but are not limited to: polyols, such as triethylene glycol, 1,3-butylene glycol, and glycerol; esters of polyols, such as glycerol mono-, di- or tri-acetate; and fatty acid esters of mono-, di- or poly-carboxylic acids, such as dimethyldodecanedioate and dimethyltetradecanedioate. Preferably, the aerosol-forming agent is polyols or a mixture thereof, such as triethylene glycol, 1,3-butylene glycol, and glycerol.

[0203] The aerosol-forming material 33 may further include a perfume. The perfume may include a volatile aroma component. In some embodiments, the perfume may include menthol. The term “menthol” is used for indicating any form of an isomer of a compound 2-isopropyl-5-methylcyclohexanol. The perfume may provide an aroma selected from the group consisting of menthol, lemon, vanilla, orange, holly, cherry, and cinnamon. The perfume may include a volatile tobacco perfume compound that is released from the material upon heating.

[0204] The aerosol-forming material 33 may further include tobacco or a tobacco-containing material. For example, the aerosol-forming material 33 may include any one of the following: tobacco leaves, tobacco vein segments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco. Optionally, the aerosol-forming material 33 may include tobacco powder compressed with, for example, glass or ceramic or another suitable inert material. In a preferred embodiment, the aerosol-forming material includes a homogenized tobacco material. The aerosol-forming material 33 may alternatively include a non-tobacco-containing aerosol-forming material.

[0205] In a case that the aerosol-forming material 33 includes a liquid or a gel, in some embodiments, the aerosol-forming product 30 may include an adsorbent carrier. The aerosol-forming material 33 may be coated on the adsorbent carrier or impregnated into the adsorbent carrier. For example, the nicotine compound and the aerosol-forming agent may be combined with water as a liquid formulation. In some embodiments, the liquid formulation may further include a perfume. Such liquid formulations may then be absorbed by the adsorbent carrier or coated onto a surface of the adsorbent carrier. The adsorbent carrier may be a sheet or tablet of a cellulose-based material onto which the nicotine compound and the aerosol-forming agent may be coated or absorbed.

[0206] When the aerosol-forming material 33 includes a solid aerosol-forming material, the solid aerosol-forming material may include one or more forms of pulverized, granulated, powdered, granular, striped, filamentous, fragmented, or laminar solids, including one or more of the following: herbaceous plant leaves, tobacco leaves, tobacco ribs, expanded tobacco, and homogenized tobacco. When the aerosol-forming material 33 includes a plant material, one or more of roots, stems, leaves, flowers, buds, seeds, and the like of a plant may be included.

[0207] Optionally, the solid aerosol-forming material may include tobacco or non-tobacco volatile aroma compounds that are released upon heating of the solid aerosol-forming material. The solid aerosol-forming material may further include one or more capsules, such as capsules including additional tobacco volatile aroma compounds or non-tobacco volatile aroma compounds, and such capsules may melt during heating of the solid aerosol-forming material.

[0208] Optionally, the solid aerosol-forming material may be disposed on a thermally stable carrier or embedded into the thermally stable carrier. The carrier may take the form of powders, granules, pellets, fragments, strips, bars, or sheets. The solid aerosol-forming material may be deposited on a surface of the carrier, for example, in the form of a sheet, a foam, a gel, or a slurry. The solid aerosol-forming material may be deposited on the entire surface of the carrier, or alternatively, may be deposited in a patterned form to provide inconsistent aroma delivery during use.

[0209] In some embodiments, the aerosol-forming product 30 may be adapted to the atomization device 40 detachably. Specifically, the atomization device 40 may include a suction nozzle 10 and a main unit 20 adapted to each other. The suction nozzle 10 is detachably disposed at one end of the main unit 20. An air outlet channel 11 is formed in the suction nozzle 10. The aerosol-forming product 30 is adapted between the suction nozzle 10 and the main unit 20, and is communicated with the air outlet channel 11. The main unit 20 can generate, after being powered on, energy to heat the aerosol-forming material 33 stored in the aerosol-forming product 30. An aerosol formed after the aerosol-forming material 33 is heated may flow out through the air outlet channel 11 for a user to take.

[0210] In some embodiments, the suction nozzle 10, the main unit 20, and the aerosol-forming product 30 are combined together detachably. The aerosol-forming product 30 is pre-loaded with the aerosol-forming material 33. After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the aerosol-forming material 33 may be updated by replacing the aerosol-forming product 30, thereby accurately controlling an amount of the aerosol-forming material 33, ensuring the quality of the aerosol-forming material 33, and avoiding introduction of other impurities in a process of manually adding the aerosol-forming material 33. In addition, because the suction nozzle 10 and the main unit 20 are reusable, use costs of the aerosol-forming system 100 are reduced. After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the aerosol-forming material 33 may alternatively be filled into the aerosol-forming product 30 by using a known filling device / method.

[0211] In some embodiments, one end of the aerosol-forming product 30 may be plugged into the main unit 20, and the other end is butted with the suction nozzle 10. An end of the main unit 20 adapted to the suction nozzle 10 may form a cavity 240 for accommodating the aerosol-forming product 30. An end of the cavity 240 close to the suction nozzle 10 has an insertion port 244. One end of the aerosol-forming product 30 may be inserted into the cavity 240 from the insertion port 244, and the other end of the aerosol-forming product 30 may extend out of the cavity 240 to be adapted to the suction nozzle 10. In other embodiments, alternatively, the other end of the aerosol-forming product 30 may not extend out of the cavity 240. To be specific, the aerosol-forming product 30 may be completely accommodated in the cavity 240. In some other embodiments, the aerosol-forming product 30 may alternatively be inserted into the suction nozzle 10.

[0212] The main unit 20 may be connected to the suction nozzle 10 magnetically, so that the main unit 20 and the suction nozzle 10 can be easily assembled and disassembled. Specifically, the end of the main unit 20 adapted to the suction nozzle 10 has a support portion 211. The cavity 240 may be formed on the support portion 211 and may be disposed coaxially with the support portion 211. The support portion 211 may be made of a material such as plastic, and the support portion 211 may be embedded with at least one magnetic member 26. The at least one magnetic member 26 may be a magnet or a magnetic material that can be attracted by the magnet. The main unit 20 is magnetically connected to the suction nozzle 10 by using the magnetic member 26. Correspondingly, the end of the main unit 20 adapted to the suction nozzle 10 may be provided with at least one magnetic member 16. The at least one magnetic member 16 and the at least one magnetic member 26 are in magnetic fit with each other.

[0213] In this embodiment, there are two magnetic members 26. The two magnetic members 26 may be respectively located at two lateral sides of the support portion 211. Correspondingly, there are two magnetic members 16. The two magnetic members 16 are respectively disposed in a one-to-one correspondence with the two magnetic members 26. It may be understood that in other embodiments, the support portion 211 may alternatively be made of a magnetic metal material, so that the magnetic members 26 are not required. In some other embodiments, the main unit 20 and the suction nozzle 10 may alternatively be connected to each other in another detachable mode such as a screwing connection or a snapping connection.

[0214] The main unit 20 may include a housing 21, and a battery 22, a circuit board 23, and a heating assembly 24 that are disposed in the housing 21. The housing 21 has a cylindrical structure, and has a cross section in various shapes such as a runway shape, an ellipse shape, a circle shape, and a square shape. This is not limited herein. The circuit board 23 is respectively electrically connected to the battery 22 and the heating assembly 24. A control chip and a related control circuit are disposed on the circuit board 23, to implement calculation and control on the device. The battery 22 is configured to supply power to electronic components such as the circuit board 23 and the heating assembly 24. The heating assembly 24 fits the aerosol-forming product 30, and is configured to heat the aerosol-forming material 33 in the aerosol-forming product 30 after being powered on.

[0215] In this embodiment, the battery 22, the circuit board 23, and the heating assembly 24 are respectively accommodated in a lower portion, a middle portion, and an upper portion of the housing 21. In other embodiments, the battery 22, the circuit board 23, and the heating assembly 24 may alternatively be arranged in the housing 21 in another mode. For example, the battery 22 and the circuit board 23 may alternatively be disposed in parallel.

[0216] In this embodiment, the main unit 20 heats the aerosol-forming material 33 by electromagnetic induction. The heating assembly 24 includes an induction heating source 242. The induction heating source 242 is electrically connected to the battery 22, and can generate an electromagnetic field after being powered on, so as to heat a sensor located in the electromagnetic field.

[0217] In this embodiment, the heating assembly 24 has a tube shape, and the cavity 240 is formed in the heating assembly 24. The induction heating source 242 may include an induction coil 2421. The induction coil 2421 may be of a helical tube shape and is disposed around the outside of the cavity 240. The induction coil 2421 may be coaxially disposed with the cavity 240, but is not limited to being coaxially disposed. Further, the heating assembly 24 may further include a holder 241 and a magnetic shield 243 sleeved outside the induction coil 2421. The holder 241 is configured to form the cavity 240, and may be configured to mount and fix the induction coil 2421. The magnetic shield 243 can reduce electromagnetic radiation from the induction coil 2421 to the outside, and can further be configured to fix the induction coil 2421.

[0218] The aerosol-forming product 30 is designed to be engaged with the main unit 20 that is electrically operated and includes the induction heating source 242. The aerosol-forming product 30 includes a sensor material. The sensor material may be coupled to the induction heating source 242 and interact with the induction heating source 242. The term “sensor material” is used for describing a material that may convert electromagnetic energy into heat. When the sensor material is located in the electromagnetic field, the electromagnetic field may generate an eddy current in the sensor material, and the eddy current may heat the sensor material by ohmic or resistive heating, to further heat the aerosol-forming material 33. In a case that the sensor material includes a ferromagnetic material (for example, iron, nickel, or cobalt), the sensor material may be further heated due to a magnetic hysteresis loss.

[0219] The sensor material may be formed of any material that may be heated by induction to enable the aerosol-forming material 33 to form an aerosol. Suitable sensor materials may include one or more of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, nickel-containing compounds, titanium, metal material composites, and the like. Preferably, the sensor material includes metal or carbon. Further, the sensor material may include or consist of a ferrite material. The ferrite material may include ferritic iron, ferromagnetic alloys (for example, ferromagnetic steel or stainless steel), ferromagnetic particles, or ferrite. In some embodiments, the sensor material may include 400-series stainless steel, for example, 410 stainless steel, 420 stainless steel, or 430 stainless steel.

[0220] It may be understood that in some other embodiments, another heat conduction mode such as heat conduction, infrared radiation, ultrasonic waves, microwaves, and plasma may alternatively be used between the heating assembly 24 and the aerosol-forming product 30.

[0221] In some other embodiments, the aerosol-forming product 30 and the suction nozzle 10 may be integrated. The integrated structure formed by the aerosol-forming product 30 and the suction nozzle 10 may be detachably fitted with the main unit 20, thereby avoiding the problem of cleaning the suction nozzle 10. The main unit 20 may be reusable, and main electronic components such as the battery 22, the circuit board 23, and the heating assembly 24 are centralized in the main unit 20, thereby reducing replacement costs.

[0222] In another embodiment, the suction nozzle 10 may alternatively be mounted on the main unit 20 in a movable adaptation mode (including, but not limited to, a mode of rotating or sliding, or a mode of popping up by being pressed). The aerosol-forming product 30 is detachably adapted between the suction nozzle 10 and the main unit 20. The aerosol-forming product 30 is covered or exposed in a mode of rotating or sliding the suction nozzle 10, and the aerosol-forming product 30 may be updated. Alternatively, the aerosol-forming product 30 may be mounted in the cavity 240 in a non-detachable mode, and an opening 311 of the aerosol-forming product 30 is exposed by rotating or sliding the suction nozzle 10, so as to fill the aerosol-forming material 33 through the opening 311. Alternatively, the aerosol-forming product 30 is popped up by pressing and the like or the aerosol-forming product 30 and the suction nozzle 10 are popped up together, to implement update of the aerosol-forming product 30.

[0223] As shown in FIG. 5 to FIG. 7, in this embodiment, the aerosol-forming product 30 is cylindrical, and may include a container 31, a heating element 32, and the aerosol-forming material 33. An accommodating cavity 310 is formed in the container 31. One end of the container 31 has the opening 311 communicating the accommodating cavity 310 with the outside. The aerosol-forming material 33 is disposed in the accommodating cavity 310 and may be communicated with the outside via the opening 311. Outside air may enter the accommodating cavity 310 via the opening 311, and then flow out through the opening 311 by carrying an aerosol formed by atomizing the aerosol-forming material 33. The heating element 32 includes a sensor material or is made of a sensor material, and may be disposed inside or outside the container 31. During use, the aerosol-forming product 30 is engaged with the main unit 20, so that the heating element 32 is located in the electromagnetic field generated by the induction heating source 242. It may be understood that in other embodiments, the aerosol-forming product 30 may alternatively not be provided with the heating element 32, but the aerosol-forming material 33 may be heated by heat conduction, infrared radiation, ultrasonic waves, microwaves, or plasma. In addition, the aerosol-forming product 30 is not limited to being cylindrical, and may alternatively be in another shape such as a square cylindrical shape or an elliptic cylindrical shape.

[0224] The container 31 may include a tubular container side wall 312 and a container bottom wall 313 disposed at one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 define the accommodating cavity 310. The other end of the container side wall 312 is opened to form an opening 311. The heating element 32 and the aerosol-forming material 33 may be loaded into the accommodating cavity 310 from the opening 311. The container bottom wall 313 may be configured to support the heating element 32 and the aerosol-forming material 33.

[0225] The container 31 may be made of a high temperature resistant material, such as glass, ceramics, metal, plastic, or aluminum foil. Further, the container 31 may be at least partially formed of a transparent material. The term “transparent” is used for describing such a material: The material allows to be passed through by at least a significant proportion of incident light, so that the material can be seen through. In the present disclosure, the substantially transparent material may allow to be passed through by sufficient light, so that the aerosol-forming material 33 in the accommodating cavity 310 is visible before being atomized. In a case that the aerosol-forming material 33 in the accommodating cavity 310 may be transparent, the substantially transparent material may allow smoke or one or more other aerosols formed by the aerosol-forming material 33 to be visible during inhaling of the aerosol-forming product 30.

[0226] The container 31 may be completely transparent. Alternatively, the container 31 may have a relatively low level of transparency, and can still transmit sufficient light, so that the aerosol-forming material 33 in the accommodating cavity 310 is visible before being atomized, or smoke or one or more other aerosols formed by the aerosol-forming material 33 are visible.

[0227] Further, the container 31 may include one or more regions formed of a transparent material, so that a part of the aerosol-forming material 33 is visible via the one or more regions. In addition, the region formed of the transparent material may be colorful, colored, or colorless.

[0228] The heating element 32 may include a ferromagnetic metal material or be made of a ferromagnetic metal material. The heating element 32 may be disposed in the container 31. On one hand, the heating element 32 can be in direct contact with the aerosol-forming material 33, and heat generated by the heating element 32 can be directly transferred to the aerosol-forming material 33, thereby improving heat transfer efficiency. On the other hand, the container 31 can have a thermal insulation function, thereby reducing heat transferred by the heating element 32 to the outside.

[0229] The shape of the heating element 32 is not limited. For example, the heating element may have various shapes such as a sheet shape, a tube shape, a barrel shape, and a helical shape. In some implementations, the heating element 32 may be disposed in the container 31 detachably. Therefore, the heating element 32 may alternatively be used as a disposable consumable. The heating element 32 may be separately replaced, thereby avoiding a cleaning problem. In addition, the structure of the heating element 32 is simple and cheap, and replacement costs are relatively low. In another implementation, the heating element 32 may alternatively be disposed in the container 31 in a non-detachable mode. It should be noted that, non-detachable means that the container 31 or the heating element 32 cannot be disassembled without being damaged, so as to be forcibly replaced.

[0230] In some embodiments, a heating cavity 320 may be formed in the heating element 32. The aerosol-forming material 33 is accommodated in the heating cavity 320. Specifically, in this embodiment, the heating element 32 is a cylindrical metal barrel, and may include a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. The heating side wall 321 and the heating bottom wall 322 jointly define the heating cavity 320. The heating bottom wall 322 may be supported on the container bottom wall 313. An opening 323 is formed at an end of the heating element 32 opposite to the heating bottom wall 322. The aerosol-forming material 33 may be loaded into the heating element 32 via the opening 323 and supported on the heating bottom wall 322. During assembly, the aerosol-forming material 33 may be first filled in the heating element 32, and then placed in the container 31 together. Alternatively, the heating element 32 may be first placed in the container 31, and then the heating element 32 is filled with the aerosol-forming material 33.

[0231] An outer diameter of the heating side wall 321 is smaller than an inner diameter of the container side wall 312. On one hand, the heating element 32 may be more easily assembled into the container 31. On the other hand, a clearance 3210 may be formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, to facilitate thermal insulation and reduce heat transferred by the heating side wall 321 to the container side wall 312.

[0232] In some embodiments, the clearance 3210 may be an annular clearance having a capillarity action. After the aerosol-forming material 33 is liquefied in a heating process, the liquid aerosol-forming material 33 can enter the clearance 3210 through a through hole 3220 provided in the heating element 32, thereby avoiding other defects that affect an atomization effect, such as generation of odor due to excessively high temperature between the heating side wall 321 of the heating element 32 and the container 31. It may be understood that in other embodiments, the clearance 3210 may alternatively have a non-capillarity structure, or some regions have a non-capillarity structure and some regions have a capillarity structure.

[0233] There may be one or more through holes 3220, which may be provided in the heating side wall 321 and / or the heating bottom wall 322 of the heating element 32. In some embodiments, the hole diameter of the through hole 3220 may be 0.5 mm to 1.5 mm. Within this range, it is possible not only to prevent the pasty aerosol-forming material 33 from flowing out of the through hole 3220, but also to enable the liquefied aerosol-forming material 33 to flow out of the through hole 3220. In addition, the through hole 3220 may further be configured to add the aerosol-forming material 33. For example, the aerosol-forming material 33 may be added to the container 31 through the through hole 3220 by injection. In other embodiments, the heating element 32 may alternatively not be provided with the through hole 3220.

[0234] In other embodiments, an outer wall surface of the heating side wall 321 and an inner wall surface of the container side wall 312 may adopt a fit mode such as transition fit or interference fit, partial clearance fit or partial interference fit.

[0235] It may be understood that in other embodiments, the heating element 32 is not limited to the foregoing structural shape. For example, the heating side wall 321 may alternatively have a tapered tube shape or a step tube shape. For another example, the heating element 32 may be a circular tube, a tapered tube, or a step tube not having the heating bottom wall 322, or may be in another shape such as a U-shaped sheet. In addition, in some other embodiments, the heating element 32 may be disposed on an outer side of the container 31. Alternatively, the heating element 32 may be partially disposed on an outer side of the container 31. Alternatively, the heating element 32 may be integrally disposed with the container 31.

[0236] In some embodiments, an inner surface of the heating element 32 may further be provided with an isolating layer. The isolating layer may include a ceramics enamel layer or a glass enamel layer. The heating element 32 is isolated from the aerosol-forming material 33 by using the isolating layer, so that an odor that may be generated in a heating process can be further avoided. The through hole 3220 provided in the heating element 32 can further enable the inner surface of the heating element 32 to be more easily plated with the enamel layer in a process of enameling, thereby ensuring that the heating element 32 is uniformly plated with the enamel layer.

[0237] Further, in some embodiments, the aerosol-forming product 30 further includes a sealing member 35. The sealing member 35 is disposed at the opening 311 of the container 31, and is configured to seal the opening 311, thereby preventing the aerosol-forming material 33 in the container 31 from flowing out, preventing external impurities from entering the container 31, and ensuring cleanness inside the container 31. In this embodiment, the sealing member 35 includes a sealing film 351. The sealing film 351 is adhered to a peripheral edge of the opening 311 in a tearing mode so as to seal the opening 311. During use, the sealing film 351 may be first torn off, to expose the opening 311. In some embodiments, the sealing film 351 may include a body portion 3511 covering the container 31 and a protrusion portion 3512 extending outward from an edge of the body portion 3511. The protrusion portion 3512 extends out of the container 31, so that a user tears off the sealing film 351 by pinching the protrusion portion 3512. In other embodiments, the sealing film 351 may alternatively be pierced to expose the opening 311.

[0238] In other embodiments, the sealing member 35 may alternatively include another sealing structure. For example, the sealing member 35 may include a thin-walled structure that can be pierced, or may include a sealing plug plugged in the opening 311, or may include a sealing cover covering the opening 311.

[0239] In some embodiments, the aerosol-forming product 30 may further include a limiting member 34 disposed in the container 31. The limiting member 34 is disposed between the sealing member 35 and the aerosol-forming material 33, and is configured to prevent the aerosol-forming material 33 from flowing to the sealing member 35 to cause waste. The limiting member 34 may be made of a high temperature resistant material, such as metal or non-metal. Further, the limiting member 34 may be made of a material incapable of heating by induction of a magnetic field, so as to prevent dry heating of the limiting member 34 caused by the fact that an amount of the aerosol-forming material 33 is reduced and is not in contact with the limiting member 34. In other embodiments, the limiting member 34 may alternatively be made of a metal material capable of heating by induction of the magnetic field.

[0240] The limiting member 34 may be disposed on an outer side of the heating element 32 or may be disposed in the heating element 32, and / or the limiting member 34 and the heating element 32 may be disposed integrally or may be disposed separately. In this embodiment, the limiting member 34 includes a mesh 341. The mesh 341 may be a metal mesh. The metal mesh has advantages such as high temperature resistance, no pollution, no odor, and low costs. The mesh 341 is formed with a plurality of airflow through holes 3410. The airflow through holes 3410 have a hole diameter in a suitable range, can allow passage of airflow, and can prevent the aerosol-forming material 33 from flowing out of the airflow through holes 3410. In addition, the mesh 341 can further prevent the aerosol-forming material 33 from splashing out when the aerosol-forming material 33 is heated. In other embodiments, the limiting member 34 may further include a hot melt film. The hot melt film can be automatically cracked or burned after being heated, is non-toxic, has no odors, and has no pollution.

[0241] In this embodiment, the mesh 341 is disposed on an outer side of the heating element 32 and abuts against an upper end surface of the heating element 32, so as to press the heating element 32 against the container bottom wall 313. At least a part of an outer wall surface of the mesh 341 is in contact with an inner wall surface of the container 31, so as to fix the mesh 341 in the container 31. Further, at least a part of the outer wall surface of the mesh 341 is in interference fit with the inner wall surface of the container 31, and the mesh 341 is fixed in the container 31 by using the interference fit. The fixing mode has a simple structure, is easy to be implemented, and is highly reliable.

[0242] In some embodiments, the mesh 341 may include a sheet-like body 3411 and a plurality of limiting flanges 3412 extending outward from an outer edge of the sheet-like body 3411. The plurality of airflow through holes 3410 may be evenly distributed on the sheet-like body 3411 in an array, for even passage of airflow. The plurality of limiting flanges 3412 may be evenly spaced apart along a peripheral direction of the sheet-like body 3411, so that the mesh 341 is evenly stressed. An outer diameter of the sheet-like body 3411 is smaller than the inner diameter of the container side wall 312. The mesh 341 is in interference fit with the container side wall 312 via the plurality of limiting flanges 3412, to facilitate loading of the mesh 341 into the container 31. It may be understood that in other embodiments, the mesh 341 may alternatively not be provided with the limiting flange 3412, but is in direct interference fit with the container side wall 312 by using the sheet-like body 3411.

[0243] Further, as shown in FIG. 3, FIG. 4, and FIG. 6, the air outlet channel 11 and the air inlet channel 12 are formed in the suction nozzle 10. Outside air may enter the accommodating cavity 310 via the air inlet channel 12, and then flow out through the air outlet channel 11 by carrying an aerosol formed by atomizing the aerosol-forming material 33. It may be understood that in other embodiments, the air inlet channel 12 may alternatively be formed in the main unit 20, or partially formed in the suction nozzle 10 and partially formed in the main unit 20, or at least a part of the air inlet channel 12 may be formed between the suction nozzle 10 and the main unit 20.

[0244] In some embodiments, the suction nozzle 10 may include an air guide tube 13. The air guide tube 13 may be made of a high temperature resistant material, such as metal or high temperature resistant plastic (for example, polyetheretherketone). An inner wall surface of the air guide tube 13 defines an air guide channel 130. The air guide channel 130 may be configured for air inlet or air outlet.

[0245] In this embodiment, the air guide tube 13 is made of a non-ferromagnetic material. The air guide tube 13 may extend along a longitudinal direction and may be disposed coaxially with the opening 311 and the accommodating cavity 310. A lower end of the air guide tube 13 may extend into the opening 311, and may further extend through the opening 311 into the accommodating cavity 310. The end of the air guide tube 13 extending into the accommodating cavity 310 is spaced apart from the mesh 341 and / or the aerosol-forming material 33. An outer diameter of the air guide tube 13 is smaller than an inner diameter of the opening 311, so that an annular vent clearance 3111 is formed between an outer wall surface of the air guide tube 13 and an inner wall surface of the opening 311. The vent clearance 3111 may be configured for passage of airflow. One of the vent clearance 3111 and the air guide channel 130 is configured for air inlet, and the other is configured for air outlet. It may be understood that in other embodiments, the air guide tube 13 and the opening 311 may alternatively not be disposed coaxially.

[0246] In some embodiments, the air inlet channel 12 may include at least one lateral airway 121 communicated with the outside and at least one central airway 122 communicating the at least one lateral airway 121 with the accommodating cavity 310. Specifically, in this embodiment, there are two lateral airways 121, to ensure sufficient air inlet. The two lateral airways 121 may be respectively symmetrically disposed on two opposite sides of the suction nozzle 10. Each lateral airway 121 extends transversely inward from an outer side surface of the suction nozzle 10. There is one central airway 122. The central airway 122 extends longitudinally and may be disposed coaxially with the accommodating cavity 310. Longitudinal ends of the central airway 122 are respectively communicated with the lateral airways 121 and the accommodating cavity 310. More specifically, in this embodiment, the central airway 122 is formed by the air guide channel 130.

[0247] The air outlet channel 11 may include an exhaust channel 112 communicated with the outside and a communication channel 111 communicating the accommodating cavity 310 with the exhaust channel 112. The exhaust channel 112 may extend longitudinally downward from a top surface of the suction nozzle 10. The communication channel 111 is disposed outside the air guide tube 13. The aerosol formed by atomizing the aerosol-forming material 33 may flow out through the vent clearance 3111, the communication channel 111, and the exhaust channel 112 in sequence from bottom to top.

[0248] The specific structure of the communication channel 111 may be flexibly designed according to requirements. For example, the communication channel 111 may include an annular airway surrounding the air guide tube 13. For another example, the communication channel 111 may alternatively include a plurality of peripheral airways spaced apart along a peripheral direction of the air guide tube 13.

[0249] In some embodiments, a flow blocking structure may be further disposed in the air outlet channel 11. The flow blocking structure is configured to block a part of the air outlet channel 11, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 after being heated. The mesh 341 disposed in the accommodating cavity 310 may alternatively prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 after being heated.

[0250] Further, in some embodiments, a side wall of the suction nozzle 10 may be further provided with an auxiliary airflow hole. The auxiliary airflow hole is communicated with the communication channel 111. In an atomization process, air in an external environment may further flow from the auxiliary airflow hole into the communication channel 111, and then may be mixed with the aerosol in the communication channel 111 to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing out of the suction nozzle 10 is adjusted.

[0251] In some embodiments, the aerosol-forming system 100 may further include a sensor 14 electrically connected to the circuit board 23. The sensor 14 is at least partially disposed in the air outlet channel 11. In one embodiment, the sensor 14 is a temperature sensor, configured to detect a temperature of the air flow in the air outlet channel 11, and transmit temperature data to the circuit board 23. A related control circuit is disposed on the circuit board 23, and can control a heating power of the heating assembly 24 according to the temperature data, and can determine, according to the temperature data, whether dry heating occurs. In this embodiment, the sensor 14 is a thermocouple, and may be disposed at one end of the exhaust channel 112 close to the communication channel 111. In other embodiments, the sensor 14 may alternatively use another sensor structure such as a thermistor, and / or the sensor 14 may alternatively be disposed at another position of the air outlet channel 11.

[0252] In other embodiments, the sensor 14 may alternatively include a pressure sensor for detecting a pressure in the air outlet channel 11, or a counting sensor for recording a quantity of inhalations. To reduce replacement costs of the sensor 14, the sensor 14 may alternatively be disposed in the main unit 20. Specifically, a part of the air outlet channel 11 may be disposed in the main unit 20, and the sensor 14 is disposed in the part of the air outlet channel 11 in the main unit 20.

[0253] Further, the suction nozzle 10 further includes two first electrodes 15 electrically connected to the sensor 14. The main unit 20 further includes two second electrodes 25 electrically connected to the circuit board 23. The two first electrodes 15 and the two second electrodes 25 respectively conduct each other in a contact conduction mode. When the suction nozzle 10 is separated from the main unit 20, the first electrodes 15 are separated from the second electrodes 25. After the suction nozzle 10 is adapted to the main unit 20, the first electrodes 15 abut against the second electrodes 25 for conduction, so as to electrically connect the sensor 14 to the circuit board 23. In this embodiment, the first electrodes 15 and the second electrodes 25 are both electrode columns, and the first electrodes 15 and / or the second electrodes 25 have elasticity, to improve reliability of electrical connection. In other embodiments, the first electrodes 15 and / or the second electrodes 25 may alternatively include another conductive connection structure such as a conductive elastic sheet. In addition, the quantity of the first electrodes 15 and the quantity of the second electrodes 25 are not limited to two.

[0254] FIG. 8 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment is also cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, a mesh 341, and a sealing film 351.

[0255] Different from the aerosol-forming product 30 in the foregoing embodiment, the container 31 in this embodiment is an aluminum foil paper tube open at two ends. Because the container 31 in this embodiment does not have the container bottom wall 313 that can play a supporting function, at least a part of an outer wall surface of the heating element 32 may be in interference fit with an inner wall surface of the container 31, so that the heating element 32 is fixed in the container 31 by using the interference fit. Further, to reduce the amount of heat transferred by the heating element 32 to the container 31 and avoid scorching of the paper tube, a mode in which a part of the outer wall surface of the heating element 32 is in interference fit with the inner wall surface of the container 31 and a part of the outer wall surface is in clearance fit with the inner wall surface of the container 31 may be used. A bottom end of the heating element 32 away from the mesh 341 may extend out of the container 31, or may not extend out of the container 31.

[0256] The heating element 32 is a metal barrel and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. In some embodiments, the heating side wall 321 may include a first side wall 3211 close to one end of the heating bottom wall 322 and a second side wall 3212 away from one end of the heating bottom wall 322. An outer diameter of the second side wall 3212 may be greater than an outer diameter of the first side wall 3211. According to a first aspect, an outer peripheral surface of the second side wall 3212 is in interference fit with an inner peripheral surface of the container 31, to fix the heating element 32 in the container 31. According to a second aspect, an outer peripheral surface of the first side wall 3211 is in clearance fit with the inner peripheral surface of the container 31, so as to reduce the amount of heat transferred by the heating element 32 to the container 31, thereby avoiding scorching of the paper tube. According to a third aspect, the aerosol-forming material 33 is mainly disposed in the first side wall 3211 close to the heating bottom wall 322. The first side wall 3211 is a main heating region. The first side wall 3211 is set to be in clearance fit with the container 31, and the second side wall 3212 is set to be in interference fit with the container 31. This is more beneficial to reducing heat transferred by the heating element 32 to the container 31.

[0257] The mesh 341 may be supported on an upper end surface of the heating element 32. An outer peripheral surface of the mesh 341 is in interference fit with the inner peripheral surface of the container 31, thereby fixing the mesh 341 in the container 31.

[0258] For the structure of the sealing film 351, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0259] FIG. 9 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment is also cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, a mesh 341, and a sealing member 35. For structures of the container 31 and the mesh 341, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0260] Similarly, the heating element 32 in this embodiment is also a metal barrel and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. Different from the foregoing embodiment, at least one protrusion 324 is formed on the heating bottom wall 322 in this embodiment. The heating bottom wall 322 abuts against the container bottom wall 313 of the container 31 by using the at least one protrusion 324, so that a direct contact area between the heating bottom wall 322 and the container bottom wall 313 can be reduced, and the amount of heat transferred by the heating element 32 to the container 31 can be reduced.

[0261] In addition, different from the foregoing embodiment, the sealing member 35 in this embodiment includes a sealing plug 352. The sealing plug 352 is detachably plugged into the container 31, thereby sealing or unsealing the opening 311.

[0262] In some embodiments, the sealing plug 352 may be made of a soft material such as silica gel, and may include a sealing portion 3522 disposed in the opening 311 in a sealing mode. The sealing plug 352 may further include an exposure portion 3521 and an extension portion 3523 that are respectively disposed at two ends of the sealing portion 3522. The exposure portion 3521 extends outward from one end of the sealing portion 3522 away from the accommodating cavity 310. The exposure portion 3521 is at least partially exposed outside the opening 311, to facilitate a user to pull out the sealing plug 352. The extension portion 3523 extends inward from the sealing portion 3522 towards one end of the accommodating cavity 310. An end of the extension portion 3523 away from the sealing portion 3522 may be pressed against the mesh 341, so as to press the mesh 341 and the heating element 32 against the container bottom wall 313, thereby avoiding sway of the mesh 341 and the heating element 32 in the container 31 during transportation of the aerosol-forming product 30. In other embodiments, the end of the extension portion 3523 away from the sealing portion 3522 may alternatively be spaced apart from the mesh 341. An outer diameter of the extension portion 3523 may be smaller than an inner diameter of the container 31, to reduce force required for assembling the sealing plug 352 into the container 31.

[0263] It may be understood that in other embodiments, the sealing plug 352 may alternatively be connected to the container 31 in a non-detachable mode. At this moment, a vent hole for airflow circulation may be provided in the sealing plug 352.

[0264] FIG. 10 to FIG. 11 show an aerosol-forming product 30 according to some embodiments of the present disclosure. A mesh 341 in this embodiment is disposed in a heating element 32.

[0265] The mesh 341 may include a sheet-like body 3411 and a plurality of limiting flanges 3412 extending outward from an outer edge of the sheet-like body 3411. The sheet-like body 3411 is provided with a plurality of airflow through holes 3410. The plurality of limiting flanges 3412 may be evenly spaced apart along a peripheral direction of the sheet-like body 3411.

[0266] The heating element 32 is a metal barrel and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. At least one protrusion 324 is formed on an outer surface of the heating bottom wall 322. The heating bottom wall 322 abuts against the container bottom wall 313 of the container 31 by using the at least one protrusion 324, so that a direct contact area between the heating bottom wall 322 and the container bottom wall 313 can be reduced, and the amount of heat transferred by the heating element 32 to the container 31 can be reduced.

[0267] In some embodiments, the heating side wall 321 may include a first side wall 3211 close to one end of the heating bottom wall 322 and a second side wall 3212 away from one end of the heating bottom wall 322. An outer diameter of the second side wall 3212 is greater than an outer diameter of the first side wall 3211, and an outer peripheral surface of the first side wall 3211 is in clearance fit with an inner peripheral surface of the container 31, so as to reduce the amount of heat transferred by the heating element 32 to the container 31.

[0268] An inner diameter of the second side wall 3212 is greater than an inner diameter of the first side wall 3211, so that a step surface 321d is formed at an inner joint between the second side wall 3212 and the first side wall 3211. The mesh 341 may be disposed in the second side wall 3212 and abut against the step surface 321d. Further, in some embodiments, a plurality of clamping slots 3214 may be formed on the second side wall 3212 and respectively correspond to the plurality of limiting flanges 3412. The plurality of limiting flanges 3412 may be respectively clamped in the plurality of clamping slots 3214, to fix the mesh 341 in the second side wall 3212.

[0269] The heating element 32 may be fixed peripherally in the container 31 by using an interference fit between the limiting flanges 3412 and the container side wall 312, or by using an interference fit between the second side wall 3212 and the container side wall 312.

[0270] FIG. 12 to FIG. 13 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment is cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, and a sealing plug 352. For structures of the container 31 and the sealing plug 352, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0271] In this embodiment, the heating element 32 is a metal barrel and is mounted in the container 31 in an inverted mode. Specifically, the heating element 32 includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. The heating bottom wall 322 is located at an end of the heating side wall 321 away from the container bottom wall 313. At least one vent hole 3221 for airflow circulation is further provided in the heating bottom wall 322, so that outside air can enter the heating element 32, and then flow out by carrying an aerosol formed by atomizing the aerosol-forming material 33 in the heating element 32. Further, to ensure even airflow, a plurality of vent holes 3221 evenly arranged in an array may be provided in the heating bottom wall 322. Each vent hole 3221 have a hole diameter in a suitable range, thereby preventing the aerosol-forming material 33 from flowing out of the vent hole 3221.

[0272] An opening 323 is formed at an end of the heating side wall 321 opposite to the heating bottom wall 322. When the aerosol-forming product 30 is assembled, the heating bottom wall 322 of the heating element 32 may be first placed downward, so that the opening 323 faces upward. Then the aerosol-forming material 33 is injected into the heating element 32 by an injection apparatus via the opening 323. Because the hole diameter of the vent holes 3221 is relatively small and the pasty aerosol-forming material 33 has particular viscosity, it is not easy for the aerosol-forming material 33 to flow out of the vent holes 3221. The aerosol-forming material 33 is injected into the heating element 32, and then the heating element 32 is inverted into the container 31, so that the opening 323 of the heating element 32 faces toward the container bottom wall 313, and the heating bottom wall 322 faces away from the container bottom wall 313.

[0273] It may be understood that in this embodiment, the heating bottom wall 322 can play a role of the mesh 341 in the foregoing embodiment. Therefore, the mesh 341 is not additionally required for the aerosol-forming product 30 in this embodiment, thereby reducing costs.

[0274] FIG. 14 to FIG. 15 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-forming material 33, a sealing film 351, a sealing plug 352, and a fixing member 36.

[0275] The container 31 is a cylindrical glass tube and may include a tubular container side wall 312 and a container bottom wall 313 disposed at one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define an accommodating cavity 310 having an opening 311 at one end. The aerosol-forming material 33 is disposed in the accommodating cavity 310.

[0276] The heating element 32 is disposed in the accommodating cavity 310 and is at least partially in contact with the aerosol-forming material 33. The heating element 32 can generate heat by induction of a magnetic field in an electromagnetic environment, so as to heat the aerosol-forming material 33. In this embodiment, the heating element 32 is approximately U-shaped and may include a heating bottom wall 322 and two heating side walls 321 respectively extending upward from two transverse ends of the heating bottom wall 322. The heating bottom wall 322 has a sheet shape and may be supported on the container bottom wall 313. The two heating side walls 321 are respectively located at two side edges of the length of the heating bottom wall 322 and may be perpendicular to the heating bottom wall 322. The length of the heating bottom wall 322 is smaller than the inner diameter of the container side wall 312. On one hand, the heating element 32 may be more easily assembled into the container 31. On the other hand, a clearance may be formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, to facilitate thermal insulation and reduce heat transferred by the heating side wall 321 to the container side wall 312.

[0277] The aerosol-forming material 33 is at least partially disposed between the two heating side walls 321. In this embodiment, the aerosol-forming material 33 is in contact with inner wall surfaces and outer wall surfaces of the two heating side walls 321, and the heating bottom wall 322, so that a contact area between the aerosol-forming material 33 and the heating element 32 is relatively large, thereby facilitating heat transfer from the heating element 32 to the aerosol-forming material 33.

[0278] It may be understood that in other embodiments, the heating element 32 is not limited to the foregoing structural shape. For example, the heating side wall 321 may be not perpendicular to the heating bottom wall 322, and / or the quantity of the heating side walls 321 may be three or more. There may alternatively be only one heating side wall 321. For example, the heating element 32 is a sheet structure having an inverted T shape.

[0279] In some embodiments, an inner surface and / or an outer surface of the heating element 32 may further be provided with an isolating layer. The isolating layer may include a ceramics enamel layer or a glass enamel layer. The heating element 32 can be isolated from the aerosol-forming material 33 by the isolating layer, so that an odor that may be generated in a heating process can be further avoided. A through hole 3220 may be further provided in the heating side wall 321 and / or the heating bottom wall 322. By providing the through hole 3220, the surface of the heating side wall 321 and / or the heating bottom wall 322 can be more easily be plated with an enamel layer in the process of enameling, thereby ensuring that the heating element 32 is evenly plated with the enamel layer. It may be understood that in other embodiments, the heating element 32 may alternatively not be provided with the through hole 3220.

[0280] The fixing member 36 is disposed in the container 31, is configured to fix the heating element 32 in the container 31 in a peripheral direction, and may be made of a high temperature resistant material, such as metal or non-metal. Further, the fixing member 36 may be disposed between the sealing plug 352 and the aerosol-forming material 33, and the fixing member 36 may further reduce waste caused by flowing of the aerosol-forming material 33 to the sealing plug 352. In some embodiments, the fixing member 36 may be made of a material incapable of heating by induction of a magnetic field, so as to prevent dry heating of the fixing member 36 caused by the fact that an amount of the aerosol-forming material 33 is reduced and is not in contact with the fixing member 36. In other embodiments, the fixing member 36 may alternatively be made of a metal material capable of heating by induction of the magnetic field.

[0281] In this embodiment, the fixing member 36 is in a sheet shape and is made of a metal material. The metal material has advantages such as high temperature resistance, no pollution, no odor, and low costs. At least a part of an outer wall surface of the fixing member 36 is in interference fit with the inner wall surface of the container 31, and the fixing member 36 is fixed in the container 31 by using the interference fit.

[0282] The fixing member 36 is provided with a flow through hole 360 for passage of airflow and a via 361 for penetration of the heating side wall 321. In this embodiment, the flow through hole 360 is located in the middle of the fixing member 36. There are two vias 361 respectively located on two opposite sides of the via 361. The heating side wall 321 may include a first side wall 3211 extending upward from the heating bottom wall 322 and a second side wall 3212 extending upward from the first side wall 3211. The width of the first side wall 3211 may be equal to the width of the heating bottom wall 322 and greater than the width of the second side wall 3212. The width of the first side wall 3211 is relatively large, so as to enlarge a heating area. The second side wall 3212 penetrates in the via 361, and a lower end surface of the fixing member 36 may abut against an upper end surface of the first side wall 3211.

[0283] It may be understood that in other embodiments, the aerosol-forming product 30 may alternatively not be provided with the fixing member 36, and the heating element 32 is fixed in the container 31 by using another structure. For example, an angle between the heating side wall 321 and the heating bottom wall 322 may be set to an obtuse angle, so that an upper end of the heating side wall 321 flares outward to abut against the inner wall surface of the container 31. For another example, the heating element 32 is made of a thermal phase change material. The heating element 32 can be in interference fit with the container 31 after being subject to thermal expansion, thereby implementing fixing of the heating element 32 in the container 31.

[0284] The sealing plug 352 is at least partially disposed in the opening 311 in a sealing mode to sealing the opening 311. Generally, at least a part of an outer wall surface of the sealing plug 352 may be in sealing fit, such as interference fit, with the inner wall surface of the opening 311. The sealing plug 352 may be made of a soft material such as silica gel, so as to improve the sealing performance of the sealing plug 352 and enable the sealing plug 352 to be more easily assembled into the container 31. In other embodiments, the sealing plug 352 may alternatively be made of a material having certain hardness, such as plastic. Further, the sealing plug 352 may be at least partially formed of a transparent material.

[0285] At least one vent channel 3524 communicating the accommodating cavity 310 to the outside atmosphere is further formed in the sealing plug 352 and / or between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31. In this embodiment, the at least one vent channel 3524 includes at least one air inlet channel 3525 and at least one air outlet channel 3526. After the suction nozzle 10, the main unit 20, and the aerosol-forming product 30 are assembled, the at least one air inlet channel 3525 communicates the accommodating cavity 310 with the air inlet channel 12. The at least one air outlet channel 3526 communicates the accommodating cavity 310 with the air outlet channel 11. In other embodiments, the at least one vent channel 3524 may alternatively include only an air inlet channel or an air outlet channel, and air outlet or air inlet from the accommodating cavity 310 may be implemented by providing a vent hole on a side wall of the container 31.

[0286] Preferably, a cross-sectional area of the at least one air inlet channel 3525 is not smaller than a cross-sectional area of the at least one air outlet channel 3526, to ensure sufficient air inlet, and ensure that the aerosol formed by atomizing the aerosol-forming material 33 can be sufficiently carried out by airflow. The cross-sectional area of a single air inlet channel 3525 or air outlet channel 3526 is relatively small, so that the aerosol-forming material 33 having a specific viscosity does not easily leak out of the air inlet channel 3525 or the air outlet channel 3526.

[0287] In this embodiment, the at least one air inlet channel 3525 and the at least one air outlet channel 3526 are both formed in the sealing plug 352. Specifically, one air inlet channel 3525 and a plurality of air outlet channels 3526 are formed in the sealing plug 352. The air inlet channel 3525 is located in the middle of the sealing plug 352. The plurality of air outlet channels 3526 are distributed on the outer periphery of the air inlet channel 3525. A cross-sectional area of the air inlet channel 3525 is not smaller than a total cross-sectional area of the plurality of air outlet channels 3526, to ensure sufficient air inlet, and ensure that the aerosol formed by atomizing the aerosol-forming material 33 can be sufficiently carried out.

[0288] Further, in this embodiment, the air inlet channel 3525 is a circular hole having a hole diameter of 2.5 mm to 3.5 mm. Alternatively, the cross-sectional area of the air inlet channel 3525 may be 4.5 mm2 to 10 mm2. Within this range, not only sufficient air inlet can be ensured, but also the aerosol-forming material 33 can be effectively prevented from leaking out of the air inlet channel 3525. The air outlet channels 3526 are waist-shaped holes. The plurality of air outlet channels 3526 are evenly spaced apart around the outer periphery of the air inlet channel 3525. The total cross-sectional area of the plurality of air outlet channels 3526 may be 2 mm2 to 9 mm2, to ensure smooth airflow circulation.

[0289] It may be understood that in other embodiments, the shapes of the air inlet channel 3525 and the air outlet channels 3526 are not limited to the foregoing shapes. In addition, the quantities and distribution modes of the air inlet channel 3525 and the air outlet channel 3526 are also not limited. For example, there is one air outlet channel 3526, and there are a plurality of air inlet channels 3525 distributed on the outer periphery of the air outlet channel 3526. For another example, there are a plurality of air outlet channels 3526 and a plurality of air inlet channels 3525. The plurality of air outlet channels 3526 may be distributed on the outer periphery or the inner periphery of the plurality of air inlet channels 3525.

[0290] The sealing plug 352 may include a sealing portion 3522 and an extension portion 3523 extending downward from the sealing portion 3522. There is a spacing between a lower end surface of the extension portion 3523 and the aerosol-forming material 33. An outer wall surface of the sealing portion 3522 is in sealing fit with the inner wall surface of the container side wall 312. The container side wall 312 may further be contracted to form a necking structure 3121. An inner diameter of the necking structure 3121 is smaller than an outer diameter of the sealing portion 3522, so that a lower end surface of the sealing portion 3522 may abut against the necking structure 3121. The necking structure 3121 can limit an axial position of the sealing portion 3522, and prevent the sealing portion 3522 from moving downward. An inner flange 3122 may be formed by extending an upper end inner wall surface of the container side wall 312. The inner flange 3122 can prevent the sealing portion 3522 from moving upward. The inner flange 3122 matches with the necking structure 3121, to clamp and fix the sealing portion 3522.

[0291] An outer diameter of the extension portion 3523 is smaller than the inner diameter of the container 31, so that an annular airflow channel 3520 is formed between an outer wall surface of the extension portion 3523 and the inner wall surface of the container 31. The air inlet channel 3525 may extend longitudinally downward from an upper end surface of the sealing portion 3522 to the lower end surface of the extension portion 3523. The air outlet channel 3526 may extend longitudinally downward from the upper end surface of the sealing portion 3522 to a lower end surface of the sealing portion 3522 and be communicated with the airflow channel 3520. This structure enables a lower air outlet of the air inlet channel 3525 to be closer to the aerosol-forming material 33 than a lower air outlet of the air outlet channel 3526. The extension portion 3523 can guide outside air to the aerosol-forming material 33 and mix the outside air with the aerosol formed by atomizing the aerosol-forming material 33. The mixed air is distributed in the airflow channel 3520 and then evenly flows into each air outlet channel 3526. It may be understood that in other embodiments, the air inlet channel 3525 may alternatively be communicated with the airflow channel 3520. To be specific, the lower air inlet of the air outlet channel 3526 is closer to the aerosol-forming material 33 than the lower air outlet of the air inlet channel 3525. In some other embodiments, the lower air inlet of the air outlet channel 3526 and the lower air outlet of the air inlet channel 3525 may alternatively be located at a same horizontal plane.

[0292] There is a spacing between the lower end surface of the extension portion 3523 and the upper end surface of the heating element 32, to facilitate thermal insulation. In other embodiments, the lower end surface of the extension portion 3523 may alternatively abut against the upper end surface of the heating element 32 or the fixing member 36, so as to press and fix the heating element 32 and the fixing member 36.

[0293] The sealing film 351 may be adhered to an upper side of the sealing plug 352, and covers at least the air inlet channel 3525 and the air outlet channel 3526. During use, the sealing film 351 may be first torn off, to expose the air inlet channel 3525 and the air outlet channel 3526. In other embodiments, the air inlet channel 3525 and the air outlet channel 3526 may be exposed by piercing the sealing film 351.

[0294] During assembly of the aerosol-forming product 30, the heating element 32 may be first loaded into the container 31. Then, the container 31 is filled with the aerosol-forming material 33, and the sealing plug 352 is plugged. Finally, the sealing film 351 is adhered.

[0295] FIG. 16 to FIG. 17 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment also includes a container 31, a heating element 32, an aerosol-forming material 33, a sealing film 351, and a sealing plug 352. For structures of the container 31, the sealing film 351, and the sealing plug 352, refer to related descriptions in the foregoing embodiment. Details are not described herein again.

[0296] The heating element 32 in this embodiment also includes a heating bottom wall 322 and two heating side walls 321 respectively extending upward from two ends of the heating bottom wall 322. Different from the foregoing embodiment, in this embodiment, at least one protrusion portion 3215 extends out from each heating side wall 321 to an inner wall surface of the container 31. In this embodiment, there are a plurality of protrusion portions 3215. The plurality of protrusion portions 3215 respectively extend from two transverse side edges of the heating side wall 321 to a direction away from the heating bottom wall 322, and may be perpendicular to the heating side wall 321. In other embodiments, the protrusion portion 3215 and the heating side wall 321 may be disposed at an acute angle or an obtuse angle. The heating element 32 may abut against the inner wall surface of the container 31 by using the protrusion portion 3215, so that the heating element 32 can be fixed in the container 31, and a fixing member 36 is not required in the container 31.

[0297] It may be understood that in other embodiments, a fixing member 36 or a limiting member 34 may alternatively be disposed in the container 31, to block the flow of the aerosol-forming material 33 to the sealing plug 352.

[0298] FIG. 18 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment also includes a container 31, a heating element 32, an aerosol-forming material 33, a sealing film 351, and a sealing plug 352.

[0299] Different from the foregoing embodiment, the heating element 32 in this embodiment is cylindrical, and may include a tubular heating side wall 321 and a heating bottom wall 322 disposed at one end of the heating side wall 321. The heating element 32 in this embodiment may be used as a container to accommodate the aerosol-forming material 33. A through hole 3220 may be further provided in the heating side wall 321 and / or the heating bottom wall 322, to ensure even enameling of the heating element 32. In some embodiments, the hole diameter of the through hole 3220 may be 0.5 mm to 1.5 mm. Within this range, it is possible to prevent the pasty aerosol-forming material 33 from flowing out of the through hole 3220.

[0300] An outer diameter of the heating side wall 321 may be smaller than or equal to an inner diameter of the container 31. When the outer diameter of the heating side wall 321 is equal to the inner diameter of the container 31, an outer wall surface of the heating side wall 321 is in contact with an inner wall surface of the container 31, so as to directly limit the heating element 32. When the outer diameter of the heating side wall 321 is smaller than the inner diameter of the container 31, the outer wall surface of the heating side wall 321 is not in contact with the inner wall surface of the container 31, which is beneficial to thermal insulation and assembly. At this moment, the heating element 32 may be limited by disposing another limiting structure.

[0301] In addition, this embodiment is further different from the foregoing embodiment in that a plurality of air inlet channels 3525 and at least one air outlet channel 3526 are formed in the sealing plug 352 in this embodiment. The plurality of air inlet channels 3525 are distributed on the outer periphery of the at least one air outlet channel 3526, and a total cross-sectional area of the plurality of air inlet channels 3525 is not smaller than a cross-sectional area of the at least one air outlet channel 3526.

[0302] During assembly of the aerosol-forming product 30, the aerosol-forming material 33 may be first filled in the heating element 32, and then placed in the container 31 together. Then, the sealing plug 352 is plugged. Finally, the sealing film 351 is adhered. Alternatively, the heating element 32 may be first placed in the container 31, and then the heating element 32 is filled with the aerosol-forming material 33. Then, the sealing plug 352 is plugged. Finally, the sealing film 351 is adhered.

[0303] FIG. 19 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference between this embodiment and the foregoing embodiments lies in that an air outlet channel 3526 in this embodiment is formed between an outer wall surface of a sealing plug 352 and an inner wall surface of a container 31, and an air inlet channel 3525 is formed in the sealing plug 352.

[0304] Specifically, there may be a plurality of air outlet channels 3526. The plurality of air outlet channels 3526 may be formed by recessing the outer wall surface of the sealing portion 3522 and may be evenly spaced apart along a peripheral direction of the sealing portion 3522.

[0305] It may be understood that in other embodiments, the air outlet channel 3525 may alternatively be formed between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31, and the air inlet channel 3526 is formed in the sealing plug 352. Alternatively, both the air inlet channel 3525 and the air outlet channel 3526 may be formed between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31.

[0306] FIG. 20 to FIG. 21 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment includes a container 31, an aerosol-forming material 33, a sealing member 38, and a sealing film 351. An accommodating cavity 310 having an opening 311 at one end is formed in the container 31. The aerosol-forming material 33 is disposed in the accommodating cavity 310. The sealing member 38 is disposed at the opening 311, and has a first state in which the opening 311 is sealed and a second state in which the opening 311 is unsealed.

[0307] Specifically, in this embodiment, the container 31 includes a container body 316 and a container cover 317 disposed at one end of the container body 316. The opening 311 is formed on the container cover 317. The container body 316 is cylindrical, and may include a tubular container side wall 312 and a container bottom wall 313 disposed at one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define the accommodating cavity 310 for accommodating the aerosol-forming material 33. An opening 318 is formed by opening the other end of the container side wall 312. The container cover 317 is disposed at the opening 318 to cover the opening 318.

[0308] The container body 316 may be made of a high temperature resistant material, such as glass, ceramics, metal, or plastic. In this embodiment, the container body 316 is made of a ferromagnetic metal material, and can generate heat by induction of a magnetic field in an electromagnetic environment, so as to heat the aerosol-forming material 33.

[0309] The container cover 317 may be made of a high temperature resistant material, such as glass, ceramics, metal, or plastic. The container cover 317 may be embedded in the opening 318. In some embodiments, the container cover317 may be riveted in the opening 318 by using an interference fit. Because the container cover 317 generally does not come into contact with the aerosol-forming material 33, to avoid dry heating, the container cover 317 may be made of a material that does not generate heat in the magnetic field or generates less heat. In this embodiment, the container cover 317 is made of a non-ferromagnetic metal material.

[0310] It may be understood that in other embodiments, when the container body 316 and the container cover 317 are made of a same material, for example, when the container body 316 and the container cover 317 are both made of a non-ferromagnetic material or a ferromagnetic material, the container body 316 and the container cover 317 may alternatively be integrally formed.

[0311] The container cover 317 may include an end cover 3171 having an annular sheet shape, an inner side wall 3172 extending downward from an inner edge of the end cover 3171, and an outer side wall 3173 extending downward from an outer edge of the end cover 3171. The outer side wall 3173 is in sealing fit with the inner wall surface of the container side wall 312. An inner wall surface of the inner side wall 3172 defines the opening 311. An outer diameter of the inner side wall 3172 is smaller than an inner diameter of the outer side wall 3173, so that an annular space 3174 is formed between an outer wall surface of the inner side wall 3172 and an inner wall surface of the outer side wall 3173. This structure is beneficial to reducing materials, reducing costs, and reducing the weight of the aerosol-forming product 30.

[0312] The sealing member 38 is at least partially detachably disposed at the opening 311. The sealing member 38 can seal the opening 311 in a first state, so that the aerosol-forming material 33 in the container 31 cannot flow out of the opening 311, thereby ensuring that the aerosol-forming material 33 in the container 31 does not leak when the aerosol-forming product 30 is disposed upright, inversely disposed, or obliquely disposed. The opening 311 can be unsealed when the sealing member 38 is in a second state, so that the accommodating cavity 310 may be communicated with the outside via the opening 311, to implement air inlet and air outlet to / from the aerosol-forming product 30. In the second state, the sealing member 38 may be completely separated from the opening 311, or partially separated from the opening 311 while being partially connected to the opening 311.

[0313] Further, in the second state, the sealing member 38 is at least partially located in the accommodating cavity 310. In this way, when the aerosol-forming material 33 remains on the sealing member 38 because the aerosol-forming product 30 is inverted or inclined, the aerosol-forming material 33 remaining on the sealing member 38 can be heated in the accommodating cavity 310 for continuous use, thereby reducing or avoiding the waste of the aerosol-forming material 33.

[0314] In this embodiment, the sealing member 38 may be completely detachably disposed at the opening 311, and is configured to be pressed and fall into the accommodating cavity 310 in the first state. In this way, when being required to be heated for use, the sealing member 38 may be poked into the accommodating cavity 310 by pressing, and the aerosol-forming material 33 remaining on the sealing member 38 may fall into the accommodating cavity 310 along with the sealing member 38, so that the aerosol-forming material 33 cannot be wasted.

[0315] In addition, in a state in which the opening 311 is unsealed, the inner side wall 3172 of the container cover 317 extends inward of the accommodating cavity 310 and surrounds around the opening 311, so as to also block the flow of the aerosol-forming material 33 out of the opening 311. Preferably, a bottom surface of the inner side wall 3172 is spaced apart from a top surface of the aerosol-forming material 33. In addition, when the aerosol-forming material 33 is pasty, a liquid level of the aerosol-forming material 33 when being heated and liquefied is lower than the bottom surface of the inner side wall 3172.

[0316] Specifically, the sealing member 38 may include a tubular sealing side wall 381 and a sealing bottom wall 382 disposed at one end of the sealing side wall 381. The sealing side wall 381 is in a shape of a hollow tube, which is beneficial to reducing materials, reducing costs, and reducing the weight of the aerosol-forming product 30. The sealing side wall 381 is configured to be in sealing fit with an inner wall surface of the opening 311 in the first state. The sealing bottom wall 382 can cover the opening 311 and can be pressed by an external force. There is a binding force between the outer wall surface of the sealing side wall 381 and the inner wall surface of the opening 311. When a pressing force on the sealing bottom wall 382 is greater than the binding force, the sealing member 38 may be separated from the opening 311 and fall into the accommodating cavity 310, so as to unseal the opening 311.

[0317] Further, the sealing side wall 381 may be in a shape of a tapered tube. Specifically, the sealing side wall 381 has an inner end (or a lower end) facing the accommodating cavity 310 and an outer end (or an upper end) facing away from the accommodating cavity 310. A cross-sectional area of the sealing side wall 381 is gradually reduced from the inner end to the outer end. Correspondingly, a cross-sectional area of the opening 311 is also gradually reduced in a direction from the inner end to the outer end. The tapered design, on one hand, may prevent the sealing member 38 from falling upward, and on the other hand, may help the sealing member 38 to fall downward away from the opening 311 when being pressed.

[0318] The sealing side wall 381 may be in interference fit with the inner wall surface of the opening 311 by clamping or the like, to ensure that the sealing member 38 is not easily released. In some embodiments, the sealing side wall 381 may include a plurality of clamping arms 3811 spaced apart along a peripheral direction. The sealing member 38 is assembled with the inner wall surface of the opening 311 by using the plurality of clamping arms 3811 through interference fit. In this embodiment, there are three clamping arms 3811 evenly spaced apart along the peripheral direction of the sealing side wall 381, facilitating even stressing. In other embodiments, the quantity of the clamping arms 3811 may alternatively be two or more than three.

[0319] In this embodiment, the sealing bottom wall 382 is disposed at the lower end of the sealing side wall 381, and the upper end of the sealing side wall 381 is open. The upper end of the sealing side wall 381 may be formed with a plurality of slots 3810 spaced apart along the peripheral direction. Each slot 3810 may extend downward from the upper end surface of the sealing side wall 381 but does not extend through the lower end surface of the sealing side wall 381. The plurality of slots 3810 divide an upper half of the sealing side wall 381 into clamping arms 3811 and body portions 3812 that are alternately distributed in the peripheral direction. The length of the clamping arms 3811 in the peripheral direction may be smaller than the length of the body portions 3812 in the peripheral direction. By means of the slots 3810, the clamping arms 3811 can expand outward, so as to be in interference fit with the inner wall surface of the opening 311. A lower half of the sealing side wall 381 is closed in the peripheral direction, and no slot structure is formed thereon, so as to prevent the aerosol-forming material 33 from seeping to the outside through the slots 3810.

[0320] It may be understood that in other embodiments, the sealing member 38 is not limited to the foregoing structural form. For example, the sealing bottom wall 382 may be disposed at the upper end of the sealing side wall 381. For another example, the sealing member 38 may be a solid structure. For another example, the sealing side wall 381 may be formed with a protrusion structure protruding outward, and is in interference fit with the inner wall surface of the opening 311 through the protrusion structure.

[0321] The sealing member 38 may be made of a high temperature resistant material, such as metal or plastic. In this embodiment, the sealing member 38 is made of a non-ferromagnetic metal material. It may be understood that because the sealing member 38 can be in contact with the aerosol-forming material 33 after falling into the accommodating cavity 310, in other embodiments, the sealing member 38 may alternatively be made of a ferromagnetic metal material. At this moment, the container body 316 may be made of a ferromagnetic material or a non-ferromagnetic material. In some other embodiments, the sealing member 38 and the container body 316 may both be made of a non-ferromagnetic material, and a heating element may be additionally disposed outside or inside the container body 316 to perform electromagnetic induction heating.

[0322] The sealing film 351 covers at least the sealing member 38, to ensure cleanness of the sealing member 38, and further prevent the sealing member 38 from being incorrectly pressed into the container 31 before use. The sealing film 351 may be a tearable sealing film and is adhered to the upper end surface of the container 31. During use, the sealing film 351 may be first torn off to expose the sealing member 38. In other embodiments, the sealing film 351 may alternatively be pierced to expose the sealing member 38.

[0323] During assembly of the aerosol-forming product 30, the aerosol-forming material 33 may be first filled in the container body 316, and the sealing member 38 is assembled onto the container cover 317. Then the container cover 317 with the sealing member 38 is riveted to the container body 316. Finally, the sealing film 351 is adhered. During use, the sealing film 351 is first torn off, and then the sealing member 38 is poked downward into the container body 316 for normal use. The aerosol-forming material 33 is disposed inside the container body 316, and does not easily flow out of the opening 311 after being heated and liquefied.

[0324] In a process of assembling the suction nozzle 10, the main unit 20, and the aerosol-forming product 30, the sealing member 38 may be poked downward through the air guide tube 13 in the suction nozzle 10, to implement air inlet and air outlet to / from the aerosol-forming product 30. At this moment, the outer diameter of the air guide tube 13 is smaller than the inner diameter of the opening 311, so that a vent clearance for airflow circulation is formed between the outer wall surface of the air guide tube 13 and the inner wall surface of the opening 311. One of the vent clearance and the air guide channel 130 may be used for air inlet, and the other may be used for air outlet. It may be understood that in other embodiments, the sealing member 38 may alternatively not be poked out by using the air guide tube 13. At this moment, the air guide tube 13 may not extend into the opening 311.

[0325] FIG. 22 to FIG. 23 show an aerosol-forming product 30 according to some embodiments of the present disclosure. In this embodiment, the container 31 includes only a container body 316. An upper end of the container body 316 is opened to form an opening 311. The container body 316 may be made of a ferromagnetic material, and can generate heat by induction of a magnetic field. The sealing member 38 may be switched from a first state in which the opening 311 is sealed to a second state in which the opening 311 is unsealed in a deformation mode, for example, a mode of heated deformation.

[0326] In some implementations, the sealing member 38 may be made of a hot melt material, and may be in a sheet shape or another shape. The sealing member 38 can fall into the container 31 after being heated and hot-melted.

[0327] In some implementations, the sealing member 38 may be made of a shape memory material. The sealing member 38 can change its shape after being heated, so as to be disconnected from the opening 311. The shapes of the sealing member 38 in the first state and the second state are not limited, as long as the opening 311 can be sealed in the first state and the opening 311 can be unsealed in the second state.

[0328] In some implementations, the sealing member 38 may include a sealing body and a hot melt adhesive connecting a peripheral edge of the sealing body to a peripheral edge of the opening 311 in a sealing mode. A material of the sealing body may be not limited. The hot melt adhesive is melted after being heated, so that the sealing body is separated from the opening 311 and falls into the container 31.

[0329] FIG. 24 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that when in the second state, the sealing member 38 in this embodiment is partially connected to the opening 311 and partially located in the accommodating cavity 310.

[0330] A mode of switching the sealing member 38 from the first state to the second state may include a deformation mode or a rotation connection mode. For example, the sealing member 38 may be made of a shape memory material, and can change its shape and switch to the second state after being heated. For another example, the sealing member 38 is rotatably connected to the opening 311, and can rotatably unseal the opening 311 by pressing or the like.

[0331] FIG. 25 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-forming material 33, and a sealing film 351. An accommodating cavity 310 having an opening 311 at one end is formed in the container 31. The aerosol-forming material 33 is disposed in the accommodating cavity 310 and may be communicated with the outside via the opening 311. Further, the container 31 includes a blocking portion 315 extending from at least a part of a peripheral edge of the opening 311 into the accommodating cavity 310 and / or away from the accommodating cavity 310. The blocking portion 315 can be configured to block the flow of the aerosol-forming material 33 out of the opening 311 when the aerosol-forming product 30 is inclined or inverted. The heating element 32 is disposed in the accommodating cavity 310 and is at least partially in contact with the aerosol-forming material 33. The heating element 32 can generate heat by induction of a magnetic field in an electromagnetic environment, and transfer the heat to the aerosol-forming material 33, so as to heat the aerosol-forming material 33.

[0332] In this embodiment, the container 31 may include a tubular container side wall 312, a container bottom wall 313 disposed at a lower end of the container side wall 312, a container top wall 314 disposed at an upper end of the container side wall 312, and a blocking portion 315 extending from the container top wall 314 into the accommodating cavity 310. The container top wall 314 has an annular plate shape, and an inner wall surface thereof defines the opening 311. A center line of the opening 311 may be parallel to or coincide with a center line of the accommodating cavity 310. The blocking portion 315 extends by a length from a peripheral edge of the opening 311 into the accommodating cavity 310. An inner wall surface of the blocking portion 315 defines a communication hole 3150 communicated with the opening 311.

[0333] In some embodiments, the outer diameter of the aerosol-forming product 30 may be 10 mm to 12 mm, and the height may be 10 mm to 12 mm. The minimum cross-sectional area of the communication hole 3150 may be 2 mm2 to 3.5 mm2, or the minimum hole diameter of the communication hole 3150 may be 1.5 mm to 2.1 mm. The height H of the blocking portion 315 may be 1.5 mm to 3 mm, or the height H of the blocking portion 315 may be ⅛ to 3 / 10 of the height of the aerosol-forming product 30. Within this range, it may be ensured that the blocking portion 315 can well block leakage of the aerosol-forming material 33.

[0334] In this embodiment, the container top wall 314 is of a concentric annulus and a center line thereof coincides with the center line of the accommodating cavity 310. The blocking portion 315 is of a circular tube and extends vertically downward from an inner wall surface of the container top wall 314. The blocking portion 315 is perpendicular to the container top wall 314, and an inner diameter and an outer diameter of the blocking portion 315 both remain unchanged in an axial direction thereof. An outer diameter of the blocking portion 315 is smaller than an inner diameter of the accommodating cavity 310, so that an outer wall surface of the blocking portion 315 is spaced apart from the inner wall surface of the container side wall 312. In addition, in this embodiment, the container 31 has an even wall thickness structure. To be specific, the container side wall 312, the container bottom wall 313, the container top wall 314, and the blocking portion 315 that constitute the container 31 have a same or approximately a same thickness. In some embodiments, the wall thickness of the container 31 may be 0.1 mm to 0.5 mm. In other embodiments, the container 31 may alternatively have an uneven wall thickness structure.

[0335] It may be understood that in other embodiments, the blocking portion 315 may have another structural shape. For example, there may be an obtuse angle or an acute angle between the blocking portion 315 and the container top wall 314. For another example, the blocking portion 315 may have another shape such as an elliptic tube or a square tube having a cross-sectional area keeping unchanged from bottom to top, or may have a tapered tube having a cross-sectional area gradually increased or reduced from bottom to top. For another example, the blocking portion 315 may alternatively have a non-closed tubular structure. Specifically, the blocking portion 315 may be formed with one or more notches extending axially.

[0336] A bottom surface of the blocking portion 315 (i.e. a surface of the blocking portion 315 close to the container bottom wall 313) and a top surface of the aerosol-forming material 33 (i.e. a surface of the aerosol-forming material 33 away from the container bottom wall 313) are spaced apart. When the aerosol-forming material 33 is pasty, a liquid level of the aerosol-forming material 33 when being heated and liquefied is lower than the bottom surface of the blocking portion 315. By means of the foregoing design, regardless of the state in which the aerosol-forming product 30 is placed upright, placed obliquely, or placed inversely, it is not easy for the aerosol-forming material 33 to leak out of the opening 311, and it is not easy for the aerosol-forming material 33 to flow out of the opening 311 after being heated and liquefied.

[0337] For the structure of the heating element 32, refer to the foregoing embodiments. Specifically, in this embodiment, the heating element 32 is cylindrical. The cylindrical heating element 32 may further be used as a container to accommodate the aerosol-forming material 33. The aerosol-forming material 33 may be loaded into the heating element 32 through the opening 311 via an upper opening of the heating element 32. An outer diameter of the heating element 32 may be smaller than or equal to an inner diameter of the container side wall 312. It may be understood that in other embodiments, the aerosol-forming product 30 may alternatively not be provided with the heating element 32.

[0338] Further, in some embodiments, the aerosol-forming product 30 may further include a sealing film 351 detachably adhered to the container 31. When being required to be heated for use, the sealing film 351 may be first torn off, to expose the opening 311, and then the aerosol-forming product 30 is assembled to the main unit 20.

[0339] The container 31 may be of an integral forming structure, and may be made of a high temperature resistant material, such as glass, ceramics, metal, or plastic. In this embodiment, the container 31 is a glass tube formed by sintering. During manufacture of the aerosol-forming product 30, the heating element 32 may be placed inside a body of the container 31, and then be formed by sintering, so that the heating element 32 and the container 31 form an integral structure by sintering. Then, the aerosol-forming material 33 is loaded into the container 31 through the opening 311. Finally, the sealing film 351 is adhered. Because the heating element 32 may be placed in the container 31 before the container 31 is formed by sintering, the size of a cross-sectional outer contour (for example, the diameter, length, or width of the cross-sectional outer contour) of the heating element 32 may be greater than, smaller than, or equal to the size of a cross-sectional outer contour of the opening 311 (for example, the diameter, length, or width of the cross-sectional outer contour). The size of the heating element 32 may be flexibly designed according to requirements.

[0340] It may be understood that in other embodiments, the container 31 may have a separate structure. For example, the container top wall 314 and the container side wall 312 are separately disposed, and / or the blocking portion 315 and the container top wall 314 are separately disposed.

[0341] FIG. 26 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 is also cylindrical and includes a container 31, a heating element 32, an aerosol-forming material 33, and a sealing film 351. For the structures of the heating element 32 and the sealing film 351, refer to related descriptions in the foregoing embodiments. Details are not described herein again.

[0342] Different from the foregoing embodiments, an upper end of the container 31 in this embodiment is not provided with a container top wall, and an upper end of the container side wall 312 is opened to form an opening 311. Specifically, in this embodiment, the container 31 includes a tubular container side wall 312, a container bottom wall 313 disposed at a lower end of the container side wall 312, and a blocking portion 315 extending from an upper peripheral edge of the container side wall 312 into the accommodating cavity 310.

[0343] The blocking portion 315 further has a tendency to contract toward the center of the opening 311, so that the minimum cross-sectional area of a cross-sectional inner contour of the blocking portion 315 is smaller than the cross-sectional area of the opening 311. In this embodiment, a tube wall of the blocking portion 315 has an arc shape, and both an outer diameter and an inner diameter of the blocking portion 315 are gradually reduced and contracted in an arc from an end close to the opening 311 to an end away from the opening 311.

[0344] FIG. 27 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment includes a contracted section 3151 extending from an upper peripheral edge of the container side wall 312 into the accommodating cavity 310 and an extension section 3152 extending from an end of the contracted section 3151 away from the opening 311. The contracted section 3151 has a frustum cone shape, and both an outer diameter and an inner diameter of the contracted section 3151 are gradually reduced and contracted in a straight from an end close to the opening 311 to an end away from the opening 311. The extension section 3152 is in a shape of a horizontally disposed annular plate, and extends inward radially by a distance from an end of the contracted section 3151 away from the opening 311. In other embodiments, the extension section 3152 may alternatively be disposed obliquely or vertically.

[0345] FIG. 28 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the container 31 in this embodiment has a separate structure, and includes a container body 316 and a container cover 317 disposed at an upper end of the container body 316.

[0346] The container body 316 has a cylindrical shape with an open upper end, and includes a container bottom wall 313 and a tubular container side wall 312 extending upward from a peripheral edge of the container bottom wall 313. The container cover 317 may include a container top wall 314 covering an upper end of the container side wall 312 and a blocking portion 315 extending downward from an inner peripheral edge of the container top wall 314.

[0347] In addition, the blocking portion 315 may further include a first blocking section 3153 and a second blocking section 3154 extending from a lower end of the first blocking section 3153. An angle (including a right angle, an acute angle, and an obtuse angle) is formed between the first blocking section 3153 and the second blocking section 3154. Specifically, in this embodiment, the first blocking section 3153 is vertically disposed, and an inner diameter and an outer diameter of the first blocking section 3153 remain unchanged in an axial direction thereof. The second blocking section 3154 is disposed at an angle with a vertical direction, and an inner diameter and an outer diameter of the second blocking section 3154 are gradually reduced in a direction away from the opening 311 in an axial direction thereof. In other embodiments, the blocking portion 315 may alternatively have a one-section structure, or may include three or more blocking sections.

[0348] The container body 316 and the container cover 317 may be made of different materials, or may be made of a same material. In one embodiment, the container body 316 is made of a ferromagnetic metal material, and can generate heat by induction of a magnetic field in the magnetic field, so as to heat the aerosol-forming material 33 accommodated in the container body 316. The container cover 317 is made of a non-ferromagnetic metal material, so as to avoid dry heating. In this case, the container 31 does not need to be additionally provided with a heating element.

[0349] In another embodiment, the container body 316 and the container cover 317 are both made of a non-ferromagnetic material, and a heating element is disposed in the container 31 to generate heat.

[0350] FIG. 29 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment extends from a peripheral edge of the opening 311 in a direction away from the accommodating cavity 310.

[0351] Similar to the foregoing embodiments, in this embodiment, the blocking portion 315 also has a tendency to contract toward the center of the opening 311, so that the minimum cross-sectional area of a cross-sectional inner contour of the blocking portion 315 is smaller than the cross-sectional area of the opening 311. Specifically, in this embodiment, the blocking portion 315 has a tapered tube shape disposed coaxially with the opening 311 and the accommodating cavity 310, and a cross-sectional area of the blocking portion 315 is gradually reduced in a direction away from the opening 311.

[0352] FIG. 30 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment extends from a partial edge of the opening 311 in a direction away from the accommodating cavity 310.

[0353] Specifically, the blocking portion 315 may extend obliquely upward from an edge of one side of the opening 311 to the other side. Further, a projection of the blocking portion 315 on the opening 311 along a vertical direction (or along an axial direction of the container 31) can block at least a large part of the opening 311, thereby providing a better leakage preventing effect.

[0354] FIG. 31 shows an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the blocking portion 315 in this embodiment includes an inner blocking portion 3155 extending from a partial peripheral edge of the opening 311 to the accommodating cavity 310 and an outer blocking portion 3156 extending from a partial peripheral edge of the opening 311 to a direction away from the accommodating cavity 310.

[0355] The inner blocking portion 3155 and the outer blocking portion 3156 may respectively extend from edges of two opposite sides of the opening 311. Further, a projection of the inner blocking portion 3155 on the opening 311 along the vertical direction partially overlaps a projection of the outer blocking portion 3156 on the opening 311 along the vertical direction, so that a leakage preventing effect is better.

[0356] As shown in FIG. 32 and FIG. 33, an aerosol-forming product 30 in some embodiments of the present disclosure includes a container 31 and a heating element 32 disposed in the container 31. The container 31 may have a cylindrical shape with an open upper end, and may include a tubular container side wall 312 and a container bottom wall 313 covering a lower end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define an accommodating cavity 310 with an open upper end. In other embodiments, the container 31 is not limited to being cylindrical, and may alternatively be of another cylindrical shape such as an elliptic cylinder or a square cylinder, or may be of a tube with two open ends.

[0357] The shape of the heating element 32 is not limited. For example, the heating element may have various shapes such as a sheet shape, a tube shape, a barrel shape, and a helical shape. Specifically, in this embodiment, the heating element 32 has a cylindrical shape with an open upper end, and may include a tubular heating side wall 321 and a heating bottom wall 322 disposed at a lower end of the heating side wall 321. The heating bottom wall 322 may abut against the container bottom wall 313 of the container 31.

[0358] At least two outer positioning portions 3124 may protrude outward from an outer wall surface of the container side wall 312. The at least two outer positioning portions 3124 are spaced apart in a peripheral direction of the container side wall 312. When the container 31 is loaded into the cavity 240 of the main unit 20, the at least two outer positioning portions 3124 are attached to a cavity wall surface of the cavity 240, so that the container 31 can be centrally positioned in the cavity 240. The container side wall 312 is in clearance fit with the cavity wall surface of the cavity 240, so as to facilitate insertion and pull out of the container 31, and further help to reduce heat transferred by the container 31 to the main unit 20. In other embodiments, at least two positioning portions may protrude inward from the cavity wall surface of the cavity 240, so that a part of an outer wall surface of the container side wall 312 abuts against the at least two positioning portions, thereby positioning the container 31 in the cavity 240.

[0359] Preferably, there are at least three outer positioning portions 3124. The at least three outer positioning portions 3124 are evenly spaced apart in the peripheral direction of the container side wall 312. Each outer positioning portion 3124 may extend downward from a top end to a bottom end of the container side wall 312 along a straight line. To be specific, an extension direction of each outer positioning portion 3124 is parallel to an axial direction of the container side wall 312, to facilitate processing and forming. In other embodiments, the outer positioning portion 3124 may alternatively have another structural form. For example, the outer positioning portion may alternatively extend obliquely downward from the top of the container side wall 312 along a straight line (to be specific, an angle is formed with the axial direction of the container side wall 312), or may alternatively extend along a non-straight line. In addition, in some other embodiments, each outer positioning portion 3124 may alternatively not be formed on the entire axial length of the container side wall 312, for example, may extend upward from the bottom end of the container side wall 312 by a distance but does not reach the top end of the container side wall 312.

[0360] Further, an outer surface (i.e. a surface away from the central axis of the container 31) of the outer positioning portion 3124 is an arc surface or is at least partially an arc surface. The outer surface of the outer positioning portion 3124 abuts against the cavity wall surface of the cavity 240 via the arc surface, so as to reduce or avoid damage caused by scraping the cavity wall surface of the cavity 240 during insertion and pull out of the container 31.

[0361] Each outer positioning portion 3124 may include a solid structure, or may include a hollow structure. Specifically, in this embodiment, each outer positioning portion 3124 has a solid structure with an approximately semi-circular cross section. In other embodiments, each outer positioning portion 3124 may alternatively be a hollow structure with an approximately semi-annular cross section.

[0362] At least two inner positioning portions 3125 may protrude inward from an inner wall surface of the container side wall 312. The at least two inner positioning portions 3125 are spaced apart in a peripheral direction of the container side wall 312. An outer wall surface (i.e. a surface away from the central axis of the heating element 32) of the heating side wall 321 of the heating element 32 may abut against the at least two inner positioning portions 3125, to centrally position the heating element 32 in the container 31, thereby ensuring temperature uniformity of the heating element 32 and consistency of a heating effect. However, the outer wall surface of the heating side wall 321 is in clearance fit with an inner wall surface of the container side wall 312, so as to form a clearance 3210. On one hand, the heating element 32 can be more easily assembled into the container 31 or removed from the container 31. On the other hand, thermal isolation between the heating element 32 and the container 31 is facilitated, thereby reducing heat transferred by the heating side wall 321 to the container side wall 312.

[0363] Preferably, there are at least three inner positioning portions 3125. The at least three inner positioning portions 3125 are evenly spaced apart in the peripheral direction of the container side wall 312. Each inner positioning portion 3125 may extend downward from a top end to a bottom end of the container side wall 312 along a straight line. To be specific, an extension direction of each inner positioning portion 3125 is parallel to an axial direction of the container side wall 312, to facilitate processing and forming. In other embodiments, the inner positioning portion 3125 may alternatively have another structural form. For example, the outer positioning portion may alternatively extend obliquely downward from the top of the container side wall 312 along a straight line (to be specific, an angle is formed with the axial direction of the container side wall 312), or may alternatively extend along a non-straight line. In addition, in some other embodiments, each inner positioning portion 3125 may alternatively not be formed on the entire axial length of the container side wall 312, for example, may extend upward from the bottom end of the container side wall 312 by a distance but does not reach the top end of the container side wall 312.

[0364] Further, an inner surface (i.e. a surface close to the central axis of the container 31) of the inner positioning portion 3125 is an arc surface or is at least partially an arc surface. An outer surface of the inner positioning portion 3125 abuts against the heating side wall 321 via the arc surface, so as to reduce or avoid scraping damage caused during insertion and pull out of the heating element 32.

[0365] Each inner positioning portion 3125 may include a solid structure, or may include a hollow structure. Specifically, in this embodiment, each inner positioning portion 3125 has a solid structure with an approximately semi-circular cross section. In other embodiments, each inner positioning portion 3125 may alternatively be a hollow structure with an approximately semi-annular cross section.

[0366] The quantity of the inner positioning portions 3125 and the quantity of the outer positioning portions 3124 may be equal or not equal. In addition, the plurality of inner positioning portions 3125 and the plurality of outer positioning portions 3124 may completely overlap or be completely staggered in the peripheral direction of the container side wall 312, or may partially overlap and be partially staggered. In this embodiment, there may be three inner positioning portions 3125 and three outer positioning portions 3124. The three inner positioning portions 3125 and the three outer positioning portions 3124 completely overlap in the peripheral direction of the container side wall 312. More specifically, each inner positioning portion 3125 is combined with the corresponding outer positioning portion 3124 to form a cylindrical solid convex column.

[0367] FIG. 34 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, there may be three inner positioning portions 3125 and three outer positioning portions 3124. The three inner positioning portions 3125 and the three outer positioning portions 3124 completely overlap in the peripheral direction of the container side wall 312. Each inner positioning portion 3125 and each outer positioning portion 3124 both have a semi-annular cross section. Each inner positioning portion 3125 and the corresponding outer positioning portion 3124 are combined to form an annular hollow convex column.

[0368] FIG. 35 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, there may be three inner positioning portions 3125 and three outer positioning portions 3124. The three inner positioning portions 3125 and the three outer positioning portions 3124 are completely staggered in the peripheral direction of the container side wall 312.

[0369] FIG. 36 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, the container side wall 312 of the container 31 is provided with only an inner positioning portion 3125 but is not provided with an outer positioning portion 3124. In other embodiments, the container side wall 312 of the container 31 may alternatively be provided with only an outer positioning portion 3124 but is not provided with an inner positioning portion 3125.

[0370] FIG. 37 shows a container 31 according to some embodiments of the present disclosure. In this embodiment, there are two inner positioning portions 3125, and the two inner positioning portions 3125 are respectively located on two radially opposite sides of the container side wall 312. There are also two outer positioning portions 3124, and the two outer positioning portions 3124 are respectively located on two radially opposite sides of the container side wall 312. The two inner positioning portions 3125 and the two outer positioning portions 3124 may overlap or may be staggered in the peripheral direction of the container side wall 312.

[0371] In other embodiments, the shapes and quantities of the inner positioning portion 3125 and the outer positioning portion 3124 are not limited, provided that the heating element 32 can be positioned in the container 31 and the container 31 can be fixed in the cavity 240. For example, there may be only one inner positioning portion 3125, which may have a convex ring shape. Similarly, there may be only one outer positioning portion 3124, which may have a convex ring shape. For another example, the inner positioning portion 3125 and / or the outer positioning portion 3124 may alternatively be distributed in a convex point shape. The positioning portion may alternatively be formed by protruding from the heating element 32, or may be formed by protruding from the cavity wall surface of the cavity 240.

[0372] As shown in FIG. 38 to FIG. 40, an aerosol-forming system 100 according to a twenty-fifth embodiment of the present disclosure includes a housing 21, an aerosol-forming product 30, a heating control assembly 27, and a suction nozzle 10. The heating control assembly 27 is disposed in the housing 21. One end of the housing 21 is provided with a cavity for accommodating the aerosol-forming product 30. The aerosol-forming product 30 is replaceably disposed in the cavity. An aerosol-forming material 33 for forming an aerosol is stored in the aerosol-forming product 30. The suction nozzle 10 is detachably adapted to the aerosol-forming product 30 and is communicated with the aerosol-forming product 30. After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the entire aerosol-forming product 30 may be pulled out from the housing 21 and separated from the suction nozzle 10 to replace a new aerosol-forming product 30. The heating control assembly 27 may heat the aerosol-forming material 33 in the aerosol-forming product 30 to form an aerosol, and the aerosol may flow out through the suction nozzle 10 for a user to take.

[0373] With reference to FIG. 41 to FIG. 43, the aerosol-forming product 30 includes a container 31, a sealing cover 353, and a central tube 354. The container 31 has a cylindrical structure and has an accommodating cavity 310 with an open end. The sealing cover 353 is mounted at the open end of the container 31, and a first vent channel 3533 and a second vent channel 3534 respectively communicating the accommodating cavity 310 with the outside atmosphere are provided in the sealing cover 353. An outer diameter of the central tube 354 is smaller than an inner diameter of the container 31 and is disposed in the accommodating cavity 310. One axial end of the central tube 354 is adapted to the sealing cover 353 and is communicated with the first vent channel 3533. The other axial end of the central tube 354 extends toward a tube bottom of the container 31 to be spaced apart from the tube bottom. A clearance between the central tube 354 and the container 31 is communicated with the second vent channel 3534.

[0374] One of the first vent channel 3533 and the second vent channel 3534 may be used as an air inlet channel, and the other vent channel may be used as an air outlet channel. In some embodiments, outside air may enter the accommodating cavity 310 through the second vent channel 3534 in sequence, and then flow out through the central tube 354 and the first vent channel 3533 by carrying an aerosol formed by atomizing the aerosol-forming material 33. In some other embodiments, outside air may enter the accommodating cavity 310 through the first vent channel 3533 and the central tube 354 in sequence, and then flow out through the second vent channel 3534 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0375] In some other embodiments, the sealing cover 353 may alternatively be provided with only an air inlet channel or an air outlet channel. In some other embodiments, the first vent channel 3533 and / or the second vent channel 3534 may alternatively be formed between the sealing cover 353 and the container 31.

[0376] Specifically, the sealing cover 353 has a cylindrical structure with an open end, and includes a sealing top wall 3531 and a sealing side wall 3532. The sealing side wall 3532 extends from an edge of the sealing top wall 3531 to a same direction and surrounds the sealing top wall 3531 along a peripheral direction. An end of the sealing side wall 3532 away from the sealing top wall 3531 is clamped with the container 31. Therefore, the sealing cover 353 and the container 31 form a non-detachable whole. The first vent channel 3533 and the second vent channel 3534 are both provided in the sealing top wall 3531, so as to be butted with the suction nozzle 10. As a preferred implementation, an edge of an open end of the container 31 is folded outward to form an annular clamping portion 3123, and a clamping slot is provided in a side wall of the sealing cover 353 to clamp the clamping portion 3123.

[0377] It may be understood that an adaptation mode between the sealing cover 353 and the container 31 is not limited thereto, and a non-detachable connection mode, such as screwing buckle connection or soldering may alternatively be used for assembly, thereby avoiding introduction of impurities due to that a user disassembles the aerosol-forming product 30 and voluntarily adds the aerosol-forming material 33, and ensuring the quality of the aerosol-forming material 33. It should be noted that, non-detachable means that disassembly is not implemented without being damaged, mainly to prevent the aerosol-forming product 30 from being secondarily added with the aerosol-forming material 33, and to achieve forced entire replacement.

[0378] The aerosol-forming product 30 further includes an annular sealing ring 355. The sealing ring 355 is disposed at a joint between the sealing top wall 3531 and the open end of the container 31, and communication holes correspondingly communicated with the first vent channel 3533 and the second vent channel 3534 are formed. In this way, the sealing ring 355 may seal a clearance between the sealing cover 353 and the container 31, so as to effectively prevent airflow in the accommodating cavity 310 from leaking from the clearance between the sealing cover 353 and the container 31, and keep airflow in the first vent channel 3533 and the second vent channel 3534 smooth.

[0379] It may be understood that a sealing mode between the container 31 and the sealing cover 353 is not limited. In some other embodiments, sealing may be performed by using an end surface interference fit and a radial interference fit.

[0380] Specifically, in an embodiment, one first vent channel 3533 and three second vent channels 3534 are provided in the sealing top wall 3531 of the sealing cover 353. The first vent channel 3533 is located at a center position of the sealing top wall 3531, and the three second vent channels 3534 surround the first vent channel 3533 along a peripheral direction. It may be understood that the quantities and the position relationship of the first vent channel 3533 and the second vent channel 3534 are not limited, and may be set according to requirements to satisfy different atomization requirements.

[0381] The central tube 354 has a hollow tubular structure with two open ends. The central tube 354 is formed of a high temperature resistant material such as metal or high temperature resistant plastic (for example, polyetheretherketone (PEEK)), thereby preventing from being fused at a high temperature during an atomization process. In an embodiment, the first vent channel 3533 is located at a center position of the sealing top wall 3531. Therefore, the central tube 354 connected to the first vent channel 3533 is disposed coaxially with the container 31. A gap between the central tube 354 and a side wall of the container 31 surrounds the central tube 354 along a peripheral direction.

[0382] It may be understood that the length of insertion of the central tube 354 into the accommodating cavity 310 is not limited, and may be set according to requirements, so that airflow may flow out by fully carrying an aerosol formed by the aerosol-forming material 33 at the bottom of the accommodating cavity 310.

[0383] In some embodiments, the aerosol-forming product 30 further includes a heating element. The heating element is accommodated in the accommodating cavity 310. The housing 21 is provided with a component capable of generating a magnetic field. The heating element may be configured to be heated by induction in the magnetic field, to atomize the aerosol-forming material 33.

[0384] It may be understood that in some other embodiments, the aerosol-forming product 30 may alternatively not be provided with the heating element, but the aerosol-forming material 33 may be heated by infrared radiation, microwaves, or plasma.

[0385] The suction nozzle 10 is adapted to the sealing cover 353 of the aerosol-forming product 30. Corresponding to the structure of the aerosol-forming product 30, the suction nozzle 10 has a first airway and a second airway spaced apart. When the aerosol-forming product 30 is adapted to the housing 21, an end of the aerosol-forming product 30 not provided with the sealing cover 353 is inserted in the cavity, and an end of the aerosol-forming product 30 provided with the sealing cover 353 extends out of the cavity to be butted with the suction nozzle 10. The first airway of the suction nozzle 10 communicates the first vent channel 3533 with the outside atmosphere, and the second airway communicates the second vent channel 3534 with the outside atmosphere.

[0386] Specifically, in some embodiments, to match positions of the first vent channel 3533 and the second vent channel 3534, the first airway of the suction nozzle 10 extends through the suction nozzle 10 in an axial direction, a central axis of the first airway and a central axis of the suction nozzle 10 overlap, and the second airway surrounds the first airway along a peripheral direction.

[0387] In this way, when a user inhales, under a negative pressure, airflow in an external environment flows from the second airway into the suction nozzle 10, and then reaches the bottom of the accommodating cavity 310 through the second vent channel 3534. Afterwards, the airflow flows out of the suction nozzle 10 through the central tube 354, the first vent channel 3533, and the first airway by carrying an aerosol formed by atomizing the aerosol-forming material 33, for the user to take.

[0388] Referring to FIG. 40, in a twenty-fifth embodiment, the first airway of the suction nozzle 10 includes an exhaust channel 112 and a communication channel 111 communicated with each other. The second airway includes a central airway 122 and a lateral airway 121 communicated with each other. An air inlet end of the lateral airway 121 is provided in a side wall of the suction nozzle 10. One end of the central airway 122 is communicated with the first vent channel 3533. The exhaust channel 112 is disposed at an end of the suction nozzle 10 communicated with the atmosphere. The communication channel 111 is spaced apart on the outer periphery of the central airway 122. One end of the communication channel 111 is communicated with the second vent channel 3534, and the other end of the communication channel 111 is communicated with the exhaust channel 112.

[0389] In this way, air in the external environment sequentially flows into the accommodating cavity 310 through the lateral airway 121, the central airway 122, the first vent channel 3533, and the central tube 354, and then flows out of the suction nozzle 10 in sequence through the communication channel 111, the second vent channel 3534, and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0390] As shown in FIG. 44, in some embodiments, the first airway of the suction nozzle 10 includes an exhaust channel 112 and a central airway 122 that are communicated with each other and are coaxially disposed. One end of the exhaust channel 112 is communicated with the outside atmosphere, and the other end of the exhaust channel 112 is connected to one end of the central airway 122. The other end of the central airway 122 is connected to the first vent channel 3533. The second airway includes a communication channel 111. The communication channel 111 is spaced apart on the outer periphery of the central airway 122. An air inlet end of the communication channel 111 is provided in a side wall of the suction nozzle 10. An air outlet end of the communication channel 111 is communicated with the second vent channel 3534.

[0391] In this way, air in the external environment enters the suction nozzle 10 from the communication channel 111, reaches the bottom of the accommodating cavity 310 through the second vent channel 3534, and then flows out of the suction nozzle 10 in sequence through the central tube 354, the first vent channel 3533, the central airway 122, and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0392] Further, in some embodiments, the suction nozzle 10 is further provided with a flow blocking baffle 17. The flow blocking baffle 17 is disposed on an inner wall of the exhaust channel 112 or the central airway 122 to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0393] Specifically, in an embodiment, the flow blocking baffle 17 includes a flow blocking top wall and a flow blocking side wall extending from the flow blocking top wall in a same direction. An end of the flow blocking side wall away from the flow blocking top wall is inserted at an outlet end of the central airway 122. The flow blocking top wall shields the outlet end of the central airway 122, and a lateral air outlet communicating the central airway 122 with the exhaust channel 112 is provided in the flow blocking side wall.

[0394] In this way, aerosol particles with a large diameter in the central airway 122 are adhered to the inner side of the outlet end of the central airway 122 or the flow blocking baffle 17 by collision, and will not enter the oral cavity of a user to affect the inhaling feeling. In addition, the flow blocking baffle 17 may shield the outlet end of the central airway 122, to prevent the user from adding the aerosol-forming material 33 through the central airway 122.

[0395] Optionally, in some embodiments, a vent hole communicated with the communication channel 111 may be further provided in an airway wall of the central airway 122. In this way, air in the external environment enters the suction nozzle 10 from the communication channel 111, reaches the bottom of the accommodating cavity 310 through the second vent channel 3534, and then flows out of the suction nozzle 10 in sequence through the central tube 354, the first vent channel 3533, the central airway 122, and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, a part of the airflow flowing into the communication channel 111 may partially flow into the central airway 122 through the vent hole, and may be mixed with an aerosol in the central airway 122 to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing out of the suction nozzle 10 is adjusted.

[0396] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, and an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0397] As shown in FIG. 45, an aerosol-forming system 100 according to some embodiments of the present disclosure includes a housing 21, an aerosol-forming product 30, a heating control assembly 27, and a suction nozzle 10. The heating control assembly 27 is disposed in the housing 21. One end of the housing 21 is provided with a cavity for accommodating the aerosol-forming product 30. The aerosol-forming product 30 is replaceably disposed in the cavity. The suction nozzle 10 is detachably mounted to the housing 21 and is sleeved outside the aerosol-forming product 30. The aerosol-forming product 30 may be communicated with the outside atmosphere through the suction nozzle 10. The aerosol-forming material 33 is stored in the aerosol-forming product 30. The heating control assembly 27 is configured to supply heat to the cavity, so as to heat the aerosol-forming material 33 in the aerosol-forming product 30 to form an aerosol for a user to take.

[0398] Referring to FIG. 46 to FIG. 48, the aerosol-forming product 30 includes a container 31, a holder 37, and an airway framework 380. The container 31 has an accommodating cavity 310, with an open end, for accommodating the aerosol-forming material 33. An axial end of the holder 37 is adapted to the open end of the container 31. An axial end of the airway framework 380 is adapted to the other axial end of the holder 37. The other axial end of the airway framework 380 is adapted to the suction nozzle 10. The airway framework 380 includes a first airway and a second airway spaced apart. The first airway is communicated with the accommodating cavity 310 and the suction nozzle 10. The second airway is communicated with the accommodating cavity 310 and the outside atmosphere. The two airways are separately spaced apart, and are communicated with each other through the accommodating cavity 310 in the aerosol-forming product 30.

[0399] In this way, the container 31 and the airway framework 380 are connected to each other through the holder 37. Air in the external environment may flow into the accommodating cavity 310 through the second airway. An aerosol formed by atomizing the aerosol-forming material 33 in the accommodating cavity 310 may flow into the suction nozzle 10 through the first airway, for a user to take. The aerosol-forming product 30 integrates the container 31 and the airway framework 380. Therefore, by replacing the entire aerosol-forming product 30, the aerosol-forming material 33 can be updated and the airway can be replaced at the same time, thereby accurately controlling the amount of the aerosol-forming material 33, ensuring cleanness of the airway, and effectively preventing health problems caused by non-timely and incomplete cleaning of the airway.

[0400] The holder 37 has a hollow tubular structure with two open ends. The container 31 has a hollow cylindrical structure with an open end. The open end of the container 31 is inserted into an axial end of the holder 37. The airway framework 380 has a hollow rotary structure. An axial end of the airway framework 380 is inserted into the other axial end of the holder 37. In this way, the container 31 and the airway framework 380 are respectively inserted into two axial ends of the holder 37 to be connected to each other through the holder 37. The container 31 is provided with only one opening at the top for communicating with the airway framework 380, and a communication hole is not provided at a bottom wall and a side wall thereof.

[0401] Further, the two axial ends of the holder 37 are respectively provided with a first clamping portion 371 and a second clamping portion 373. The open end of the container 31 is provided with a container clamping portion 3127 matching the first clamping portion 371. An axial end of the airway framework 380 is provided with a framework clamping portion matching the second clamping portion 373. In this way, the container clamping portion 3127 and the first clamping portion 371 are clamped with each other, and the second clamping portion 373 and the framework clamping portion are clamped with each other, so that the container 31, the holder 37, and the airway framework 380 form a non-detachable whole. It should be noted that, non-detachable means that disassembly is not implemented without being damaged, mainly to prevent the aerosol-forming product 30 from being secondarily added with the aerosol-forming material 33, and to achieve forced entire replacement.

[0402] Specifically, in an embodiment, an edge of an axial end of the holder 37 is folded inward, to form an annular first clamping portion 371. An edge of the open end of the container 31 is folded outward, to form an annular container clamping portion 3127. A lower surface of the container clamping portion 3127 is configured to abut against an upper surface of the first clamping portion 371. When a user attempts to pull the holder 37 and the container 31 apart from each other, the first clamping portion 371 may play a role of preventing the container clamping portion 3127 from moving, so as to prevent the holder 37 and the container 31 from being separated from each other.

[0403] An inner surface of a part of the side wall of the other axial end of the holder 37 protrudes outward, so as to form the second clamping portion 373 in the form of an annular protrusion. An outer surface of a part of the side wall of the airway framework 380 extending into the holder 37 is recessed inward, to form a framework clamping portion having an annular groove shape. The shape of the framework clamping portion matches the shape of the second clamping portion 373, so as to be embedded in the second clamping portion 373. When the user attempts to pull the holder 37 and the airway framework 380 apart from each other, the second clamping portion 373 may play a role of preventing the framework clamping portion from moving, so as to prevent the holder 37 and the airway framework 380 from being separated from each other.

[0404] It may be understood that an adaptation mode of the holder 37 to the container 31 and the airway framework 380 is not limited thereto. In some other embodiments, a non-detachable mode, such as screwing buckle connection or ultrasonic soldering may alternatively be used for assembly, thereby preventing the aerosol-forming product 30 from being disassembled by the user. In addition, the holder 37 and the container 31 or the holder 37 and the airway framework 380 may be integrally formed in a forming mode such as printing. The integral forming means that the holder 37 and the container 31 or the holder 37 and the airway framework 380 form an integral structure. The integral structure has features of the holder 37 and the container 31 or the holder 37 and the airway framework 380. In other words, the holder 37 may be omitted, and related features on the holder 37 may be formed on the container 31 or the airway framework 380.

[0405] Referring to FIG. 46 to FIG. 48 again, specifically, in some embodiments, the airway framework 380 includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. A lateral airway 383b is further provided in the framework body 383. An air inlet end of the lateral airway 383b is disposed on the side wall of the framework body 383 and extends radially into the framework body 383 from the outer surface of the side wall of the framework body 383. A connection hole communicated with the lateral airway 383b is provided in the framework body 383, and a central axis of the connection hole and a central axis of the framework body 383 overlap. One end of the central tube 384 is inserted into the connection hole, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0406] It may be understood that in some embodiments, the central tube 384 is detachably connected to the framework body 383. In some other embodiments, the central tube 384 and the airway framework 380 are integrally formed. As a preferred implementation, the central tube 384 is formed of a material such as metal or high temperature resistant plastic (for example, polyetheretherketone (PEEK)), thereby preventing the central tube 384 from being fused at a high temperature during an atomization process.

[0407] In this way, an end of the framework body 383 located outside the holder 37 forms an exhaust channel 383a communicated with the outside atmosphere. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The exhaust channel 383a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 384 forms a central airway 384a. The central airway 384a and the lateral airway 383b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 384a.

[0408] When a user inhales, air in the external environment may flow into the central airway 384a through the lateral airway 383b, flow to the bottom of the accommodating cavity 310 along the central airway 384a, and then flow into the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0409] As shown in FIG. 49 and FIG. 50, in some embodiments of the present disclosure, the airway framework 380 also includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. A lateral airway 383b is further provided in the framework body 383. An air inlet end of the lateral airway 383b is disposed on the side wall of the framework body 383 and extends radially into the framework body 383 from the outer surface of the side wall of the framework body 383. A connection hole communicated with the lateral airway 383b is provided in the framework body 383, and a central axis of the connection hole and a central axis of the framework body 383 overlap. One end of the central tube 384 is inserted into the connection hole, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0410] In this way, an end of the framework body 383 located outside the holder 37 forms an exhaust channel 383a communicated with the outside atmosphere. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The exhaust channel 383a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 384 forms a central airway 384a. The central airway 384a and the lateral airway 383b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 384a.

[0411] Different from the foregoing embodiments, an auxiliary airflow hole communicated with the edge airway 310a is further provided in the side wall of the framework body 383 of the airway framework 380 in this embodiment. An auxiliary air inlet hole communicating the auxiliary airflow hole with the outside atmosphere is provided in the side wall of the holder 37.

[0412] When a user inhales, air in the external environment may flow into the central airway 384a through the lateral airway 383b, flow to the bottom of the accommodating cavity 310 along the central airway 384a, and then flow into the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material33. At the same time, air in the external environment may further enter the edge airway 310a through the auxiliary air inlet hole and the auxiliary airflow hole, and then may be mixed with an aerosol in the edge airway 310a to reduce the concentration of the an aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing into the suction nozzle 10 is adjusted.

[0413] As shown in FIG. 51, in some embodiments, the airway framework 380 includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. One end of the central tube 384 is inserted into the framework body 383, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0414] In this way, an exhaust channel 383a communicated with the outside atmosphere is formed in an end of the framework body 383 located outside the holder 37. A central airway 384a is formed in the central tube 384. The central airway 384a and the exhaust channel 383a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 384a, and an opening at one end of the edge airway 310a is disposed on the side wall of the framework body 383, to form the foregoing first airway.

[0415] When a user inhales, air in the external environment may flow to the bottom of the accommodating cavity 310 through the edge airway 310a, and then flow into the suction nozzle 10 in sequence through the central airway 384a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0416] As shown in FIG. 52, and FIG. 53, in some embodiments, the airway framework 380 includes a framework body 383 and a central tube 384. The framework body 383 has a hollow rotary structure. An axial end of the framework body 383 is inserted into the holder 37. The framework clamping portion is formed on an outer surface of a side wall of the framework body 383. One end of the central tube 384 is inserted into the framework body 383, and the other end of the central tube 384 extends into the accommodating cavity 310 along an axial direction of the framework body 383.

[0417] In this way, an exhaust channel 383a communicated with the outside atmosphere is formed in an end of the framework body 383 located outside the holder 37. A central airway 384a is formed in the central tube 384. The central airway 384a and the exhaust channel 383a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 384, a side wall of the framework body 383, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 384a, and an opening at one end of the edge airway310a is disposed on the side wall of the framework body 383, to form the foregoing first airway.

[0418] Different from the foregoing embodiments, in this embodiment, a vent hole 384b is provided in a tube wall of the central tube 384. The vent hole 384b is communicated with outlet ends of the edge airway 310a and the central airway 384a.

[0419] When a user inhales, air in the external environment may flow to the bottom of the accommodating cavity 310 through the edge airway 310a, and then flow into the suction nozzle 10 in sequence through the central airway 384a and the exhaust channel 383a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, airflow flowing from an edge air inlet 383d into the edge airway 310a may partially enter the central airway 384a through the vent hole 384b on the central tube 384, and may be mixed with an aerosol in the central airway 384a to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing into the suction nozzle 10 is adjusted.

[0420] Further, in some embodiments, as shown in FIG. 51 and FIG. 52, the aerosol-forming product 30 further includes a flow blocking baffle 39. The flow blocking baffle 39 is disposed on an inner wall of the exhaust channel 383a or the central airway 384a to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0421] Specifically, in an embodiment, the flow blocking baffle 39 includes a flow blocking top wall 392 and a flow blocking side wall 394 extending from the flow blocking top wall 392 in a same direction. An end of the flow blocking side wall 394 away from the flow blocking top wall 392 is inserted at an outlet end of the central airway 384a. The flow blocking top wall 392 shields the outlet end of the central airway 384a, and a lateral air outlet communicating the central airway 384a with the exhaust channel 383a is provided in the flow blocking side wall 394.

[0422] In this way, aerosol particles with a large diameter in the central airway 384a are adhered to the inner side of the outlet end of the central airway 384a or the flow blocking baffle 39 by collision, and will not enter the oral cavity of a user to affect the inhaling feeling. In addition, the flow blocking baffle 39 may shield the outlet end of the central airway 384a, to prevent the user from adding the aerosol-forming material 33 through the central airway 384a.

[0423] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, or an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0424] Referring to FIG. 47 and FIG. 48 again, in some embodiments, the aerosol-forming product 30 further includes an annular sealing member 385. The sealing member 385 is clamped between the container clamping portion 3127 and an end surface of the airway framework 380, to seal a clearance between the container 31 and the airway framework 380, thereby preventing airflow in the edge airway 310a from leaking from the clearance between the container 31 and the airway framework 380. It may be understood that in some other embodiments, sealing may be formed by an end surface interference contact and a radial interference contact, and the sealing member 385 is not required.

[0425] In some embodiments, the aerosol-forming product 30 further includes a damping member 386. The damping member 386 is sleeved outside the airway framework 380. Specifically, in an embodiment, an outer surface of the side wall of the airway framework 380 is formed with an annular accommodating groove extending along a peripheral direction, and the damping member 386 is annular to be embedded in the accommodating groove. When the aerosol-forming product 30 is inserted into an atomization device, the damping member 386 forms a particular damping with the atomization device, thereby preventing the aerosol-forming product 30 from sliding off the atomization device. It may be understood that a mode of improving connection stability between the aerosol-forming product 30 and the atomization device is not limited thereto, and a magnetic connection, a snapping connection, or a screwing buckle connection may alternatively be used.

[0426] Referring to FIG. 54 to FIG. 56, an aerosol-forming system 100 according to some embodiments of the present disclosure includes a housing 21, an atomizer 50, and a heating control assembly 27. The heating control assembly 27 is disposed in the housing 21. A cavity for accommodating the atomizer 50 is disposed at one end of the housing 21. The atomizer 50 is replaceably disposed in the cavity. An aerosol-forming material 33 is stored in the atomizer 50. The heating control assembly 27 is configured to supply heat to the cavity, so as to heat the aerosol-forming material 33 in the atomizer 50 to form an aerosol for a user to take.

[0427] After the aerosol-forming material 33 in the atomizer 50 is used up, the entire atomizer 50 may be pulled out from the heating control assembly 27 to replace a new atomizer 50, and the aerosol-forming material 33 in the atomizer 50 does not need to be manually added, thereby accurately controlling the amount and quality of the aerosol-forming material 33, and avoiding introduction of other impurities in a process of manually adding the aerosol-forming material.

[0428] Referring to FIG. 57 to FIG. 59, the atomizer 50 includes a container 31, a holder 37, and a suction nozzle 10. The container 31 has an accommodating cavity 310, with an open end, for accommodating the aerosol-forming material 33. An axial end of the holder 37 is adapted to the open end of the container 31. The suction nozzle 10 is adapted to the other axial end of the holder 37. The suction nozzle 10 includes a first airway and a second airway spaced apart, and the first airway and the second airway are respectively communicated with the accommodating cavity 310 and the outside atmosphere. To be specific, the first airway is communicated with the accommodating cavity 310 and the outside atmosphere, and the second airway is also communicated with the accommodating cavity 310 and the outside atmosphere. The two airways are separately spaced apart, and are communicated with each other through the accommodating cavity 310 in the atomizer 50.

[0429] In this way, the container 31 and the suction nozzle 10 are connected to each other through the holder 37. Air in the external environment may flow into the accommodating cavity 310 through one of the first airway and the second airway. An aerosol formed by atomizing the aerosol-forming material 33 in the accommodating cavity 310 may flow out through the other one of the first airway and the second airway, for a user to take. The atomizer 50 integrates the container 31, the suction nozzle 10, and the airway function. Therefore, by replacing the entire atomizer 50, the aerosol-forming material 33 can be updated and the suction nozzle 10 and the airway can be replaced at the same time, thereby accurately controlling the amount and quality of the aerosol-forming material 33, ensuring cleanness of the suction nozzle 10, and effectively preventing health problems caused by non-timely and incomplete cleaning of the suction nozzle 10.

[0430] The holder 37 has a hollow tubular structure with two open ends. The container 31 has a hollow cylindrical structure with an open end. The open end of the container 31 is inserted into an axial end of the holder 37. The suction nozzle 10 has a hollow rotary structure. An axial end of the suction nozzle 10 is inserted into the other axial end of the holder 37. In this way, the container 31 and the suction nozzle 10 are respectively inserted into two axial ends of the holder 37 to be connected to each other through the holder 37. The container 31 is provided with only one opening at the top for communicating with the suction nozzle 10, and a communication hole is not provided at a bottom wall and a side wall thereof.

[0431] Further, the two axial ends of the holder 37 are respectively provided with a first clamping portion 371 and a second clamping portion 373. The open end of the container 31 is provided with a container clamping portion 3127 matching the first clamping portion 371. An axial end of the suction nozzle 10 is provided with a suction nozzle clamping portion matching the first clamping portion 371. In this way, the container clamping portion 3127 and the first clamping portion 371 are clamped with each other, and the second clamping portion 373 and the suction nozzle clamping portion are clamped with each other, so that the container 31, the holder 37, and the suction nozzle 10 form a non-detachable whole.

[0432] Specifically, in an embodiment, an edge of an axial end of the holder 37 is folded inward, to form an annular first clamping portion 371. An edge of the open end of the container 31 is folded outward, to form an annular container clamping portion 3127. A lower surface of the container clamping portion 3127 is configured to abut against an upper surface of the first clamping portion 371. When a user attempts to pull the holder 37 and the container 31 apart from each other, the first clamping portion 371 may play a role of preventing the container clamping portion 3127 from moving, so as to prevent the holder 37 and the container 31 from being separated from each other.

[0433] An inner surface of a part of the side wall of the other axial end of the holder 37 protrudes outward, so as to form the second clamping portion 373 in the form of an arc protrusion. An outer surface of a part of the side wall of the suction nozzle 10 extending into the holder 37 is recessed inward, to form a suction nozzle clamping portion having an arc groove shape. The shape of the suction nozzle clamping portion matches the shape of the second clamping portion 373, so as to be embedded in the second clamping portion 373. When the user attempts to pull the holder 37 and the suction nozzle 10 apart from each other, the second clamping portion 373 may play a role of preventing the suction nozzle clamping portion from moving, so as to prevent the holder 37 and the suction nozzle 10 from being separated from each other.

[0434] It may be understood that an adaptation mode of the holder 37 to the container 31 and the holder 37 to the suction nozzle 10 is not limited thereto. In some other embodiments, a non-detachable mode, such as screwing buckle connection or soldering may alternatively be used for assembly, thereby preventing the atomizer 50 from being disassembled by the user. In addition, the holder 37 and the container 31 or the holder 37 and the suction nozzle 10 may be integrally formed in a forming mode such as 3D printing.

[0435] Referring to FIG. 57 to FIG. 59 again, specifically, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. A lateral airway 102b is further provided in the suction nozzle body 102. An air inlet end of the lateral airway 102b is disposed on the side wall of the suction nozzle body 102 and extends radially into the suction nozzle body 102 from the outer surface of the side wall of the suction nozzle body 102. A connection hole communicated with the lateral airway 102b is provided in the suction nozzle body 102, and a central axis of the connection hole and a central axis of the suction nozzle body 102 overlap. One end of the central tube 104 is inserted into the connection hole, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0436] It may be understood that in some embodiments, the central tube 104 is detachably connected to the suction nozzle body 102. In some other embodiments, the central tube 104 and the suction nozzle body 102 are integrally formed. As a preferred implementation, the central tube 104 is formed of a material such as metal or high temperature resistant plastic (for example, polyetheretherketone (PEEK)), thereby preventing the central tube 104 from being fused at a high temperature during an atomization process.

[0437] In this way, an end of the suction nozzle body 102 located outside the holder 37 forms an exhaust channel 102a communicated with the outside atmosphere. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The exhaust channel 102a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 104 forms a central airway 104a. The central airway 104a and the lateral airway 102b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 104a.

[0438] When a user inhales, air in the external environment may flow into the central airway 104a through the lateral airway 102b, flow to the bottom of the accommodating cavity 310 along the central airway 104a, and then flow out of the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0439] As shown in FIG. 60, and FIG. 61, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. A lateral airway 102b is further provided in a side wall of the suction nozzle body 102. An air inlet of the lateral airway 102b is disposed on the side wall of the suction nozzle body 102 and extends radially into the suction nozzle body 102 from the outer surface of the side wall of the suction nozzle body 102. A connection hole communicated with the lateral airway 102b is provided in the suction nozzle body 102, and a central axis of the connection hole and a central axis of the suction nozzle body 102 overlap. One end of the central tube 104 is inserted into the connection hole, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0440] In this way, an end of the suction nozzle body 102 located outside the holder 37 forms an exhaust channel 102a communicated with the atmosphere. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The exhaust channel 102a and the edge airway 310a are communicated with each other to jointly form a first airway. The central tube 104 forms a central airway 104a. The central airway 104a and the lateral airway 102b are communicated with each other to form a second airway, and the edge airway 310a is disposed on the outer periphery of the central airway 104a.

[0441] Different from the foregoing embodiments, an auxiliary airflow hole 102c communicated with the edge airway 310a is further provided in the side wall of the suction nozzle body 102 in this embodiment. An auxiliary air inlet hole 375 communicating the auxiliary airflow hole 102c with the outside atmosphere is provided in the side wall of the holder 37.

[0442] When a user inhales, air in the external environment may flow into the central airway 104a through the lateral airway 102b, flow to the bottom of the accommodating cavity 310 along the central airway 104a, and then flow out of the suction nozzle 10 in sequence through the edge airway 310a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, air in the external environment may further enter the edge airway 310a through the auxiliary air inlet hole 375 and the auxiliary airflow hole 102c, and then may be mixed with an aerosol in the edge airway 310a to reduce the concentration of the an aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing out of the suction nozzle 10 is adjusted.

[0443] As shown in FIG. 56, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. One end of the central tube 104 is inserted into the suction nozzle body 102, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0444] In this way, an exhaust channel 102a communicated with the outside atmosphere is formed in an end of the suction nozzle body 102 located outside the holder 37. A central airway 104a is formed in the central tube 104. The central airway 104a and the exhaust channel 102a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 104a, and an opening at one end of the edge airway 310a is disposed on the side wall of the suction nozzle body 102, to form the foregoing first airway.

[0445] When a user inhales, air in the external environment may flow to the bottom of the accommodating cavity 310 through the edge airway 310a, and then flow out of the suction nozzle 10 in sequence through the central airway 104a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0446] As shown in FIG. 63, and FIG. 64, in some embodiments, the suction nozzle 10 includes a suction nozzle body 102 and a central tube 104. The suction nozzle body 102 has a hollow rotary structure. An axial end of the suction nozzle body 102 is inserted into the holder 37. The suction nozzle clamping portion is formed on an outer surface of a side wall of the suction nozzle body 102. One end of the central tube 104 is inserted into the suction nozzle body 102, and the other end of the central tube 104 extends into the accommodating cavity 310 along an axial direction of the suction nozzle body 102.

[0447] In this way, an exhaust channel 102a communicated with the atmosphere is formed in an end of the suction nozzle body 102 located outside the holder 37. A central airway 104a is formed in the central tube 104. The central airway 104a and the exhaust channel 102a are communicated with each other and are coaxially disposed to jointly form a first airway. An edge airway 310a is formed between the central tube 104, a side wall of the suction nozzle body 102, and a cavity wall of the accommodating cavity 310. The edge airway 310a is spaced apart on the outer periphery of the central airway 104a, and an opening at one end of the edge airway 310a is disposed on the side wall of the suction nozzle 10, to form the foregoing first airway. As an alternative solution of an opening at one end of the edge airway 310a, an air clearance may be provided between the side wall of the suction nozzle10 and the holder 37. The air clearance is communicated with the edge airway 310a.

[0448] Different from the foregoing embodiments, in this embodiment, a vent hole 104b is provided in a tube wall of the central tube 104. The vent hole 104b is communicated with outlet ends of the edge airway 310a and the central airway 104a.

[0449] When a user inhales, air in the external environment may flow into the accommodating cavity 310 through the edge airway 310a, and then flow out of the suction nozzle 10 in sequence through the central airway 104a and the exhaust channel 102a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, airflow flowing into the edge airway 310a may partially enter the outlet end of the central airway 104a through the vent hole 104b, and may be mixed with an aerosol in the central airway 104a to adjust the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing out of the suction nozzle 10 is adjusted.

[0450] Further, in some embodiments, as shown in FIG. 62 and FIG. 63, the atomizer 50 further includes a flow blocking baffle 55. The flow blocking baffle 55 is disposed on an inner wall of the exhaust channel 102a or the central airway 104a to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0451] Specifically, in an embodiment, the flow blocking baffle 55 includes a flow blocking top wall 552 and a flow blocking side wall 554 extending from the flow blocking top wall 552 in a same direction. An end of the flow blocking side wall 554 away from the flow blocking top wall 552 is inserted at an outlet end of the central airway 104a. The flow blocking top wall 552 shields the outlet end of the central airway 104a, and a lateral air outlet communicating the central airway 104a with the exhaust channel 102a is provided in the flow blocking side wall 554.

[0452] In this way, aerosol particles with a large diameter in the central airway 104a are adhered to the inner side of the outlet end of the central airway 104a or the flow blocking baffle 55 by collision, and will not enter the oral cavity of a user to affect the inhaling feeling. In addition, the flow blocking baffle 55 may shield the outlet end of the central airway 104a, to prevent the user from adding the aerosol-forming material 33 through the central airway 104a.

[0453] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, or an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0454] In some embodiments, the atomizer 50 further includes a first sealing member 105 and a second sealing member 106 that are annular. The first sealing member 105 is disposed at a joint between the container clamping portion 3127 and the suction nozzle body 102, to seal a clearance between the container 31 and the suction nozzle body 102, thereby preventing airflow in the first edge airway 310a and the second edge airway 310a from leaking from a clearance between the container 31 and the suction nozzle 10. The second sealing member 106 is disposed at a joint between the suction nozzle 10 and the holder 37, so as to seal a clearance between the suction nozzle 10 and the holder 37 and avoid air leakage. In addition, when the atomizer 50 is inserted into the housing 21, a particular amount of damping is formed between the second sealing member 106 and the housing 21, so as to prevent the atomizer 50 from sliding off the housing 21.

[0455] It may be understood that in some other embodiments, sealing may be formed by an end surface interference contact and a radial interference contact, and the first sealing member 105 and the second sealing member 106 are not required. A mode of improving stability of connection between the atomizer 50 and the heating control assembly 27 is not limited thereto, and a magnetic connection, a snapping connection, or a screwing buckle connection may alternatively be used.

[0456] As shown in FIG. 65 to FIG. 68, an aerosol-forming system 100 according to a thirty-fifth embodiment of the present disclosure includes a housing 21, an atomizer 50, and a heating control assembly 27. The heating control assembly 27 is disposed in the housing 21. One end of the housing 21 is provided with a cavity for accommodating the atomizer 50. The atomizer 50 is separably disposed in the cavity. The atomizer 50 includes an aerosol-forming product 30 and a suction nozzle assembly 60. The aerosol-forming product 30 stores an aerosol-forming material 33. The suction nozzle assembly 60 is separably adapted to the aerosol-forming product 30. The heating control assembly 27 may heat the atomized aerosol-forming material 33 in the aerosol-forming product 30 to form an aerosol, and the aerosol may flow out through the suction nozzle assembly 60 for a user to take.

[0457] After the aerosol-forming material 33 in the aerosol-forming product 30 is used up, the entire atomizer 50 may be pulled out from the housing 21, and the aerosol-forming product 30 is separated from the suction nozzle assembly 60 to replace a new aerosol-forming product 30. The aerosol-forming material 33 in the aerosol-forming product 30 does not need to be manually added, thereby accurately controlling the amount and quality of the aerosol-forming material 33, and avoiding introduction of other impurities in a process of manually adding the aerosol-forming material.

[0458] The aerosol-forming product 30 includes a container 31, a sealing film 351, and the aerosol-forming material 33. The container 31 has a hollow tubular structure. The container 31 has an accommodating cavity 310 with an open end. The sealing film 351 is encapsulated at the open end of the container 31 to seal the accommodating cavity 310. Because the container 31 is sealed by the sealing film 351, air may be insulated, to prevent the aerosol-forming material 33 from oxidative deterioration, and a user is prevented from introducing impurities due to voluntary adding of the aerosol-forming material 33 to the accommodating cavity 310, thereby ensuring the quality of the aerosol-forming material 33.

[0459] The suction nozzle assembly 60 includes a suction nozzle 10 and a piercing air tube 61. The suction nozzle 10 has a hollow rotary structure, and has a first airway and a second airway that are communicated with the atmosphere and are spaced apart. One end of the piercing air tube 61 is adapted to one end of the suction nozzle 10 and is communicated with the first airway, and the other end of the piercing air tube 61 extends out of the suction nozzle 10. When the suction nozzle 10 is adapted to the aerosol-forming product 30, the suction nozzle 10 covers the open end of the container 31, and one end of the piercing air tube 61 may pierce the sealing film 351 into the accommodating cavity 310.

[0460] In this way, the piercing air tube 61 is communicated with the accommodating cavity 310 of the aerosol-forming product 30 and the first airway of the suction nozzle 10, and a gap between a side wall of the piercing air tube 61 and a cavity wall of the accommodating cavity 310 is communicated with the second airway. In some embodiments, outside air may flow into the accommodating cavity 310 through the first airway and the piercing air tube 61, and then flow into the second airway through the gap between the side wall of the piercing air tube 61 and the cavity wall of the accommodating cavity 310 by carrying an aerosol formed by atomizing the aerosol-forming material 33. In some other embodiments, the outside air may flow into the accommodating cavity 310 in sequence through the second airway and the gap between the side wall of the piercing air tube 61 and the cavity wall of the accommodating cavity 310, and then flow into the first airway by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0461] Before the atomizer 50 is used, the sealing film 351 of the aerosol-forming product 30 is pierced by using the piercing air tube 61 of the suction nozzle assembly 60, and then the entire atomizer 50 is inserted into the cavity of the aerosol-forming system 100. After activation, inhaling may be implemented. After the aerosol-forming material 33 is used up, the entire atomizer 50 may be pulled out from the aerosol-forming system 100, and then the suction nozzle assembly 60 is pulled out from the atomizer 50, to replace a new aerosol-forming product 30.

[0462] Specifically, a plurality of ridges 61a are convexly disposed on an outer side wall of the piercing air tube 61. All the ridges 61a are spaced apart along a peripheral direction of the piercing air tube 61. Each ridge 61a extends along an axial direction of the piercing air tube 61. In this way, after the piercing air tube 61 extends into the accommodating cavity 310, a gap communicated with the second airway is defined between two adjacent ridges 61a and the cavity wall of the accommodating cavity 310. It may be understood that the quantity and shape of the ridges 61a are not limited thereto, and may be set according to requirements to satisfy different requirements. It should be noted that, to avoid leakage of the aerosol after piercing, the sealing film 351 may be made of an elastic material, such as silica gel, PET, PP, or an aluminum plastic film. In addition, to ensure an appropriate depth of insertion of the piercing air tube 61 into the container 31, a limiting portion may further be disposed on the piercing air tube 61. For example, an outer wall of the piercing air tube 61 and an open end surface of a tube body form an abutting portion. There are a plurality of implementation structures, which are not described herein one by one.

[0463] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and one end of the edge airway 107a is communicated with the exhaust channel 101a. A lateral airway is further disposed in the suction nozzle 10. An air inlet end of the lateral airway is provided in a side wall of the inhaling portion 101, and an air outlet end of the lateral airway is communicated with the central airway 103a. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0464] In this way, the exhaust channel 101a and the edge airway 107a are communicated with each other to jointly form a first airway, and the exhaust channel 101a is disposed at an end of the suction nozzle 10 communicated with the outside atmosphere. The central airway 103a and the lateral airway jointly form a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. An end of the edge airway 107a away from the exhaust channel 101a is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0465] When a user inhales by using the suction nozzle 10, air in the external environment may flow into the accommodating cavity 310 in sequence through the lateral airway, the central airway 103a, and the piercing air tube 61, and then flow out of the suction nozzle 10 in sequence through the edge airway 107a and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0466] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and one end of the edge airway 107a is communicated with the exhaust channel 101a. A lateral airway is further disposed in the suction nozzle 10. An air inlet end of the lateral airway is provided in a side wall of the inhaling portion 101, and an air outlet end of the lateral airway is communicated with the central airway 103a. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0467] In this way, the exhaust channel 101a and the edge airway 107a are communicated with each other to jointly form a first airway, and the exhaust channel 101a is disposed at an end of the suction nozzle 10 communicated with the atmosphere. The central airway 103a and the lateral airway jointly form a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. An end of the edge airway 107a away from the exhaust channel 101a is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0468] An auxiliary airflow hole is provided in a side wall of the second connection portion 107 of the suction nozzle 10. The auxiliary airflow hole is communicated with the edge airway 107a. When a user inhales by using the suction nozzle 10, air in the external environment may flow into the accommodating cavity 310 in sequence through the lateral airway, the central airway 103a, and the piercing air tube 61, and then flow out of the suction nozzle 10 in sequence through the edge airway 107a and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, air in the external environment may further enter the edge airway 107a from the auxiliary air inlet hole, and then may be mixed with an aerosol in the edge airway 107a to reduce the concentration of the an aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the air flowing out of the suction nozzle 10 is adjusted.

[0469] Further, in some implementations, the suction nozzle assembly 60 further includes a flow blocking baffle 65. The flow blocking baffle 65 is disposed on an inner wall of the exhaust channel 101a or the central airway 103a to block a part of the first airway, so as to prevent the aerosol-forming material 33 from splashing out of the suction nozzle 10 when being heated.

[0470] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a that is communicated with the exhaust channel 101a and disposed coaxially with the exhaust channel 101a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and an air inlet end of the edge airway 107a is provided in the side wall of the second connection portion 107 of the suction nozzle 10. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0471] In this way, the exhaust channel 101a and the central airway 103a are communicated with each other to jointly form a first airway, and the edge airway 107a forms a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. The second airway is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0472] When a user inhales by using the suction nozzle 10, air in the external environment may enter the suction nozzle 10 from the edge airway 107a and reach the bottom of the accommodating cavity 310, and then flow out of the suction nozzle 10 in sequence through the piercing air tube 61, the central airway 103a, and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0473] In some implementations, the suction nozzle 10 includes an inhaling portion 101, a first connection portion 103, and a second connection portion 107. The first connection portion 103 and the second connection portion 107 are both connected to a same axial end of the inhaling portion 101, and the second connection portion 107 is spaced apart on the outer periphery of the second connection portion 107. An exhaust channel 101a communicated with the outside atmosphere is formed in the inhaling portion 101. A central airway 103a that is communicated with the exhaust channel 101a and disposed coaxially with the exhaust channel 101a is formed in the first connection portion 103. An edge airway 107a spaced apart on the outer periphery of the central airway 103a is formed between the first connection portion 103 and the second connection portion 107, and an air inlet end of the edge airway 107a is provided in the side wall of the second connection portion 107 of the suction nozzle 10. One end of the piercing air tube 61 is inserted at an end of the first connection portion 103 away from the inhaling portion 101 to communicate with the central airway 103a.

[0474] In this way, the exhaust channel 101a and the central airway 103a are communicated with each other to jointly form a first airway, and the edge airway 107a forms a second airway. When the suction nozzle 10 is adapted to the aerosol-forming product 30, an end of the second connection portion 107 away from the inhaling portion 101 is sleeved outside the open end of the container 31. The second airway is communicated with a gap between the piercing air tube 61 and the cavity wall of the accommodating cavity 310. An end of the piercing air tube 61 away from the first connection portion 103 extends into the accommodating cavity 310.

[0475] A vent hole communicated with the edge airway 107a is provided with an airway wall (i.e. the side wall of the second connection portion 107) of the central airway 103a. In this way, when a user inhales by using the suction nozzle 10, air in the external environment may enter the suction nozzle 10 from the edge airway 107a and reach the bottom of the accommodating cavity 310, and then flow out of the suction nozzle 10 in sequence through the piercing air tube 61, the central airway 103a, and the exhaust channel 101a by carrying an aerosol formed by atomizing the aerosol-forming material 33. At the same time, a part of the airflow flowing into the edge airway 107a may partially flow into the central airway 103a through the vent hole, and may be mixed with an aerosol in the central airway 103a to reduce the concentration of the aerosol, so that the aerosol-forming material 33 is atomized, and the temperature of the airflow flowing out of the suction nozzle 10 is adjusted.

[0476] In some embodiments, at least a part of an airway inner wall of the first airway is configured as a damping structure for hindering sliding of the aerosol-forming material 33 to the accommodating cavity 310. Specifically, the damping structure is at least one of a step, an arc surface, a rough surface, an annular groove, and an annular blocking bar that are formed on the airway inner wall of the first airway. In this way, if a user adds the aerosol-forming material 33 to the first airway, the damping structure blocks the aerosol-forming material 33 from sliding down to the accommodating cavity 310.

[0477] According to the foregoing aerosol-forming product 30 and aerosol-forming system 100, the aerosol-forming product 30 pre-loaded with the aerosol-forming material 33 may be separately connected to the suction nozzle assembly 60. The aerosol-forming material 33 can be updated by replacing the aerosol-forming product 30 without manually adding the aerosol-forming material 33 by a user, thereby accurately controlling the amount of the aerosol-forming material 33, and ensuring the quality of the aerosol-forming material 33.

[0478] Referring to FIG. 69 and FIG. 70, an atomizer 50 according to some embodiments of the present disclosure includes an aerosol-forming product 30 and a suction nozzle assembly 60. The aerosol-forming product 30 includes a container 31 having an accommodating cavity 310 formed therein and a heating element 32 disposed in the accommodating cavity 310. The suction nozzle assembly 60 may be separately adapted to the aerosol-forming product 30, or may be adapted to the aerosol-forming product 30 in a non-detachable mode.

[0479] The suction nozzle assembly 60 includes a suction nozzle 10 and an air guide tube 13. An exhaust channel 112 is formed in the suction nozzle 10, and an aerosol formed by atomization in the accommodating cavity 310 can be outputted to the outside through the exhaust channel 112, for a user to take or inhale. Further, at least one lateral airway 121 may be further formed on the suction nozzle 10, for allowing outside air to enter the accommodating cavity 310. Specifically, in this embodiment, there are two lateral airways 121. The two lateral airways 121 are respectively located at two transverse opposite sides of the suction nozzle 10, and respectively extend inward from outer surfaces of two sides of the suction nozzle 10. In other embodiments, there may alternatively be one or more lateral airways 121.

[0480] An inner wall surface of the air guide tube 13 defines an air guide channel 130. The air guide channel 130 may be configured for air inlet or air outlet to / from the accommodating cavity 310. An upper end of the air guide tube 13 may be embedded in the suction nozzle 10, and may be adapted to the suction nozzle 10 in a detachable or non-detachable mode. A lower end of the air guide tube 13 may extend into the accommodating cavity 310 and is spaced apart from a bottom wall of the container 31. An outer diameter of a tubular side wall 131 is smaller than an inner diameter of the container 31, so that an annular vent clearance 3111 is formed between an outer wall surface of the tubular side wall 131 and an inner wall surface of the container 31. One of the vent clearance 3111 and the air guide channel 130 is configured for air inlet, and the other is configured for air outlet. In other embodiments, the lower end of the air guide tube 13 may alternatively not extend into the accommodating cavity 310.

[0481] Specifically, in this embodiment, the air guide channel 130 is communicated with the exhaust channel 112, and the vent clearance 3111 is communicated with the lateral airway 121. Outside air may flow into the accommodating cavity 310 in sequence through the lateral airway 121 and the vent clearance 3111, and then flow out in sequence through the air guide channel 130 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33. In other embodiments, the air guide channel 130 may alternatively be communicated with the lateral airway 121, and the vent clearance 3111 may alternatively be communicated with the exhaust channel 112. Outside air may flow into the accommodating cavity 310 in sequence through the lateral airway 121 and the air guide channel 130, and then flow out in sequence through the vent clearance 3111 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0482] In some embodiments, the air guide tube 13 may be made of a non-ferromagnetic metal material, so as to avoid dry heating of the air guide tube 13. In addition, the metal material has advantages such as high temperature resistance, no pollution, no odor, and low costs. An upper end of the air guide tube 13 may be embedded into the suction nozzle 10 by riveting, and fixed to the suction nozzle 10 together. In other embodiments, the air guide tube 13 may alternatively be made of another high temperature resistant material, such as high temperature resistant plastic (for example, polyetheretherketone).

[0483] In some embodiments, the air guide tube 13 may include a tubular side wall 131 having a circular tube shape (alternatively, having another shape such as an elliptic tube shape or a square tube shape) and a bottom wall 132 disposed at a lower end of the tubular side wall 131. The tubular side wall 131 and the bottom wall 132 jointly define the air guide channel 130 with an open upper end. The tubular side wall 131 is provided with at least one vent hole 1310 communicating the air guide channel 130 with the accommodating cavity 310.

[0484] The bottom wall 132 is disposed at a lower end of the tubular side wall 131 and seals the lower end of the tubular side wall 131. The accommodating cavity 310 is communicated with the air guide channel 130 via the vent hole 1310 in the tubular side wall 131, so as to effectively prevent from directly inhaling the aerosol-forming material 33 into the air guide channel 130 during inhaling, thereby improving user experience. In addition, a cross-sectional through-flow area of a single vent hole 1310 is relatively small, which assists in preventing the aerosol-forming material 33 from being drawn out.

[0485] Preferably, the tubular side wall 131 is provided with a plurality of vent holes 1310. The plurality of vent holes 1310 may be evenly spaced apart in a peripheral direction and / or an axial direction of the tubular side wall 131, to assist airflow in evenly entering the air guide channel 130. The shape of each vent hole 1310 is not limited, and may be various shapes such as a circular hole shape, an elliptic hole shape, and a square hole shape. In some embodiments, the plurality of vent holes 1310 may be disposed close to the bottom wall 132, which assists in sufficiently drawing out an aerosol formed by atomizing the aerosol-forming material 33.

[0486] In other embodiments, the plurality of vent holes 1310 may alternatively be provided in the bottom wall 132, or may be provided in both the bottom wall 132 and the tubular side wall 131, which also assists in preventing the aerosol-forming material 33 from entering the air guide channel 130. In some other embodiments, the air guide tube 13 may not be provided with the bottom wall 132, and the air guide channel 130 may be zigzagged and / or a porous material may be disposed in the air guide channel 130, to prevent the aerosol-forming material 33 from splashing out of the air guide channel 130. Alternatively, a flow blocking structure may be disposed in the air guide channel 130 to block a part of the air guide channel 130, so as to prevent the aerosol-forming material 33 from splashing out of the air guide channel 130. The porous material may alternatively be directly used as an airway, and air inlet or air outlet is implemented by using micro-pores in the porous material.

[0487] In some embodiments, the suction nozzle assembly 60 may further include a connector 62. The connector 62 is at least partially disposed between an outer wall surface of the container 31 and an inner wall surface of the suction nozzle 10, and may be made of an elastic material such as silica gel. On one hand, the connector 62 made of an elastic material has good sealing performance. On the other hand, an upper end of the container 31 may be plugged into the connector 62. The container 31 is connected to the connector 62 in a pluggable mode, so that the container 31 can be conveniently assembled and disassembled in a pluggable mode. Therefore, it may be convenient to remove the container 31 from the suction nozzle assembly 60 and then add the aerosol-forming material 33 to the container 31.

[0488] It may be understood that in other embodiments, the connector 62 may alternatively be made of another material such as high temperature resistant plastic. In some other embodiments, the connector 62 may alternatively be omitted, and the container 31 may be directly plugged into the suction nozzle 10. In addition, the aerosol-forming material 33 can be updated by replacing the entire atomizer 50, so as to avoid a problem of cleaning the atomizer 50. In this way, the suction nozzle assembly 60 and the container 31 may alternatively be connected in a non-detachable mode.

[0489] In some embodiments, the connector 62 may include an annular sleeve portion 621 and an annular connection portion 622 extending inward from an inner wall surface of the sleeve portion 621. The sleeve portion 621 may be disposed between an outer wall surface of the container 31 and an inner wall surface of the suction nozzle 10 in a sealing mode. The connection portion 622 may abut against an upper end surface of the container 31, and have a through hole 6220 for passage of the air guide tube 13 and at least one vent hole 6221 communicating the lateral airway 121 with the vent clearance 3111 formed through.

[0490] The through hole 6220 may be provided in the middle of the connection portion 622. A lower end of the air guide tube 13 may pass through the through hole 6220 and further extend into the accommodating cavity 310, and an outer wall surface of the air guide tube 13 may be in sealing fit with a hole wall surface of the through hole 6220. There may be a plurality of vent holes 6221. The plurality of vent holes 6221 may surround the outer periphery of the through hole 6220 and may be evenly spaced apart in the peripheral direction, facilitating airflow to evenly enter the accommodating cavity 310.

[0491] During inhaling, outside air enters through the lateral airways 121 on two sides of the suction nozzle 10, enters the accommodating cavity 310 through the vent hole 6221 on the connector 62, and is mixed with the aerosol in the accommodating cavity 310. Then, the mixed airflow enters the air guide channel 130 through the vent hole 1310 on the air guide tube 13, and further flows out through the exhaust channel 112.

[0492] Further, the aerosol-forming product 30 may further include a limiting member 34 disposed in the container 31, for limiting the heating element 32 in the container 31. The limiting member 34 may be made of a high temperature resistant material, such as metal or non-metal. Preferably, the limiting member 34 may be made of a non-ferromagnetic metal material, so as to prevent dry heating of the limiting member 34. In addition, the metal material has advantages such as high temperature resistance, no pollution, no odor, and low costs.

[0493] Specifically, in this embodiment, the limiting member 34 may include a sheet-like body 3411. The sheet-like body 3411 is provided with a plurality of airflow through holes 3410 for passage of airflow. The sheet-like body 3411 may abut against an upper end of the heating element 32, so as to press the heating element 32 against a bottom wall of the container 31. The sheet-like body 3411 further assists in reducing or preventing the aerosol-forming material 33 from splashing out when the aerosol-forming material 33 is heated.

[0494] In this embodiment, an outer diameter of the sheet-like body 3411 is smaller than an inner diameter of the container 31. The limiting member 34 further includes at least two limiting arms 3413 disposed on the outer periphery of the sheet-like body 3411. The limiting member 34 is limited by contact between the at least two limiting arms 3413 and the container 31. Preferably, the at least two limiting arms 3413 are elastic arms and are evenly spaced apart in a peripheral direction of the sheet-like body 3411, facilitating even stressing, and being elastically pressed against the inner wall surface of the container 31 by means of an elastic force. A lower end of each limiting arm 3413 is connected to the sheet-like body 3411, and an upper end is expanded outward by an angle to be elastically pressed against the inner wall surface of the container 31.

[0495] In other embodiments, the limiting member 34 may alternatively not include the limiting arm 3413. For example, several convex hulls may be formed by extending at least a part of an outer peripheral surface of the sheet-like body 3411 outward, and the several convex hulls abut against the inner wall surface of the container 31 to implement limiting. Alternatively, the heating element 32 may be pressed against the bottom wall of the container 31 after the bottom wall 132 of the air guide tube 13 abuts against the sheet-like body 3411.

[0496] Referring to FIG. 71, an atomizer 50 according to some embodiments of the present disclosure includes an aerosol-forming product 30 and a suction nozzle assembly 60. The aerosol-forming product 30 includes a container 31 having an accommodating cavity 310 formed therein, and a heating element 32 and an aerosol-forming material 33 disposed in the accommodating cavity 310. The suction nozzle assembly 60 may be separately adapted to the aerosol-forming product 30, or may be adapted to the aerosol-forming product 30 in a non-detachable mode.

[0497] The suction nozzle assembly 60 includes a suction nozzle 10, an air inlet tube 133, and an air outlet tube 134. The suction nozzle 10 has an exhaust channel 112 and a lateral airway 121 that are respectively communicated with the atmosphere. An air inlet channel 1330 and an air outlet channel 1340 are respectively formed in the air inlet tube 133 and the air outlet tube 134. One end of the air inlet tube 133 is adapted to the suction nozzle 10 and is communicated with the lateral airway 121, and the other end of the air inlet tube 133 extends into the container 31 and is communicated with the accommodating cavity 310. One end of the air outlet tube 134 is adapted to the suction nozzle 10 and is communicated with the exhaust channel 112, and the other end of the air outlet tube 134 extends into the container 31 and is communicated with the accommodating cavity 310. Outside air may flow into the accommodating cavity 310 in sequence through the lateral airway 121 and the air inlet channel 1330, and then flow out in sequence through the air outlet channel 1340 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33.

[0498] The air inlet tube 133 and the air outlet tube 134 may alternatively be sleeved with each other. For example, the air outlet tube 134 may be sleeved outside the air inlet tube 133. The air inlet channel 1330 is formed in the air inlet tube 133. The air outlet channel 1340 is formed between an outer wall surface of the air inlet tube 133 and an outer wall surface of the air outlet tube 134. Alternatively, the air inlet tube 133 may be sleeved outside the air outlet tube 134. The air outlet channel 1340 is formed in the air outlet tube 134. The air inlet channel 1330 is formed between an outer wall surface of the air outlet tube 134 and an outer wall surface of the air inlet tube 133.

[0499] In some embodiments, the suction nozzle assembly 60 further includes a connector 62. The connector 62 is embedded in one end of the suction nozzle 10, and is formed with an air inlet hole 623 communicated with the lateral airway 121 and an air outlet hole 624 communicated with the exhaust channel 112. One end of the air inlet tube 133 may be embedded in the air inlet hole 623 and communicated with the air inlet hole 623. One end of the air outlet tube 134 may be embedded in the air outlet hole 624 and communicated with the air outlet hole 624. An open end of the container 31 is embedded in an end of the connector 62 away from the exhaust channel 112, and may be fixed to the connector 62 together by interference fit or snapping connection.

[0500] As a preferred implementation, the connector 62 may be made of an elastic material such as silica gel. On one hand, the connector 62 made of an elastic material has good sealing performance. On the other hand, upper ends of the container 31, the air inlet tube 133, and the air outlet tube 134 may be plugged into the connector 62. The container 31, the air inlet tube 133, the air outlet tube 134, and the connector 62 can be conveniently assembled and disassembled in a pluggable mode. Therefore, it may be convenient to remove the container 31 from the connector 62 and then add the aerosol-forming material 33 to the container 31, and it may be further convenient to separately replace the air inlet tube 133 and the air outlet tube 134. In other embodiments, the connector 62 may alternatively be made of another material such as high temperature resistant plastic. In some other embodiments, the connector 62 may be integrally formed with the suction nozzle 10, and / or, the connector 62 may be integrally formed with the air inlet tube 133 and the air outlet tube 134.

[0501] FIG. 72 to FIG. 75 show an atomizer 50 according to some embodiments of the present disclosure. The atomizer 50 in this embodiment also includes an aerosol-forming product 30, a suction nozzle 10, and a connector 62. For structures of the aerosol-forming product 30 and the suction nozzle 10, refer to the foregoing descriptions. Details are not described herein again.

[0502] The connector 62 in this embodiment includes an annular sleeve portion 621 and an annular airway portion 625. The sleeve portion 621 surrounds outside the airway portion 625 and may be coaxially disposed with the airway portion 625, but is not limited to being coaxially disposed. An inner wall surface of the airway portion 625 defines an air guide channel 6250, and an inner wall surface of the sleeve portion 621 and an outer wall surface of the airway portion 625 defines an air guide channel 6210. One of the air guide channel 6210 and the air guide channel 6250 may be configured for air inlet of the accommodating cavity 310, and the other is configured for air outlet of the accommodating cavity 310.

[0503] The container 31 may be sleeved between an outer wall surface of the sleeve portion 621 and an inner wall surface of the suction nozzle 10. In other embodiments, the container 31 may alternatively be sleeved in the sleeve portion 621. At this moment, the air guide channel 6210 may be formed between the inner wall surface of the container 31 and the outer wall surface of the air guide portion 625.

[0504] Further, the connector 62 further includes a connection portion 622. The sleeve portion 621 and the airway portion 625 respectively extend from one end surface of the connection portion 622 along a same direction. Specifically, in this embodiment, the sleeve portion 621 and the airway portion 625 respectively extend downward from a lower end surface of the connection portion 622 along an axial direction. The air guide channel 6250 extends through the connection portion 622, so as to communicate with one of the lateral airway 121 on the suction nozzle 10 and the exhaust channel 112. The air guide channel 6210 does not extend through the connection portion 622. The connection portion 622 is provided with at least one vent hole 6222, to communicate the air guide channel 6210 with the other one of the lateral airway 121 and the exhaust channel 112. Specifically, in this embodiment, the air guide channel 6210 is communicated with the exhaust channel 112, and the air guide channel 6250 is communicated with the lateral airway 121.

[0505] In other embodiments, a lower end surface of the connection portion 622 may alternatively extend downward to form at least two tubular airway portions 625, and air inlet and air outlet to / from the accommodating cavity 310 are implemented by using the at least two tubular airway portions 625.

[0506] In some embodiments, a communication channel 6224 communicating the air guide channel 6250 with the lateral airway 121 may be further formed between the connection portion 622 and the suction nozzle 10. The communication channel 6224 may be formed by recessing the suction nozzle 10 or the connection portion 622, or may be formed by jointly recessing the suction nozzle 10 and the connection portion 622. In this embodiment, a communication groove 6223 communicated with an upper end of the air guide tube 6250 is formed by recessing an upper end surface of the connection portion 622. The communication groove 6223 extends through two transverse sides of the connection portion 622. After the connector 62 is loaded into the suction nozzle 10, an upper end surface of the communication groove 6223 is covered by the suction nozzle 10 to form the communication channel 6224. Two transverse ends of the communication channel 6224 are respectively communicated with two lateral airways 121 on the suction nozzle 10. There are two vent holes 6222. The two vent holes 6222 are respectively located on two opposite sides of the communication groove 6223.

[0507] FIG. 76 and FIG. 77 show an atomizer 50 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that in this embodiment, the airway portion 625 has an approximately C-shaped tube shape. The airway portion 625 has an opening 6251 on a peripheral side. The opening 6251 is covered by an inner wall surface of one side of the sleeve portion 621 and / or an inner wall surface of one side of the container 31 to form an air guide channel 6250. An air guide channel 6210 is formed between an outer surface of the airway portion 625 away from the opening 6251 and an inner wall surface of the other side of the sleeve portion 621 and / or an inner wall surface of the other side of the container 31.

[0508] Specifically, in this embodiment, an upper end of the container 31 is sleeved in the sleeve portion 621 and is disposed coaxially with the sleeve portion 621. The airway portion 625 is eccentrically disposed relative to a central axis of the sleeve portion 621. An air guide channel 6250 is formed between an inner surface of a side of the airway portion 625 close to the opening 6251 and an inner surface of the container 31. An air guide channel 6210 is formed between an outer surface of a side of the airway portion 625 away from the opening 6251 and the inner surface of the container 31. The air guide channel 6250 is communicated with the lateral airway 121, and the air guide channel 6210 is communicated with the exhaust channel 112.

[0509] Similar to the foregoing embodiments, in this embodiment, a communication channel 6224 communicating the air guide channel 6250 with the lateral airway 121 is formed between the connection portion 622 and the suction nozzle 10. To be different, in this embodiment, because the air guide channel 6250 is eccentrically disposed, the communication channel 6224 does not extend through two transverse sides of the connection portion 622. Specifically, the communication channel 6224 may extend from one side of the connection portion 622 along a transverse direction to be communicated with the air guide channel 6250.

[0510] In other embodiments, any variation may alternatively be made to the foregoing structure according to requirements. For example, the container 31 may be sleeved between an outer wall surface of the sleeve portion 621 and an inner wall surface of the suction nozzle 10. For another example, the air guide channel 6250 may alternatively be communicated with the exhaust channel 112. Correspondingly, the air guide channel 6210 is communicated with the lateral airway 121.

[0511] FIG. 78 shows an atomizer 50 according to some embodiments of the present disclosure. The atomizer 50 in this embodiment also includes an aerosol-forming product 30, a suction nozzle 10, and a connector 62. To be different, at least one vent hole 3101 is provided in the container 31 in this embodiment, and is configured for air inlet or air outlet to / from the accommodating cavity 310.

[0512] Specifically, in this embodiment, a container side wall 312 of the container 31 is provided with a plurality of vent holes 3101 communicating the accommodating cavity 310 with the outside. The plurality of vent holes 3101 may be evenly spaced apart in a peripheral direction of the container side wall 312. The connector 62 is provided with an airflow channel 627 communicated with the accommodating cavity 310. Outside air may enter the accommodating cavity 310 from the plurality of vent holes 3101, and then flow out of the suction nozzle 10 in sequence through the airflow channel 627 and the exhaust channel 112 by carrying an aerosol formed by atomizing the aerosol-forming material 33. The accommodating cavity 310 implements air inlet by using the plurality of vent holes 3101, so that a channel for air inlet may not be required for the suction nozzle 10.

[0513] It may be understood that in other embodiments, the plurality of vent holes 3101 may be evenly spaced apart in an axial direction of the container side wall 312, or may be spaced apart in both a peripheral direction and an axial direction of the container side wall 312. There may alternatively be only one vent hole 3101. In addition, the vent hole 3101 may alternatively be provided in the container bottom wall 313 of the container 31.

[0514] In another embodiment, the accommodating cavity 310 may implement air outlet by using the plurality of vent holes 3101, and an aerosol formed by atomizing the aerosol-forming material 33 flows out of the suction nozzle 10 in sequence through the plurality of vent holes 3101 and the exhaust channel 112.

[0515] FIG. 79 to FIG. 80 show an aerosol-forming product 30 according to some embodiments of the present disclosure. The aerosol-forming product 30 includes a container 31, a heating element 32, and an aerosol-forming material 33. An accommodating cavity 310 having an opening 311 at one end is formed in the container 31. The heating element 32 and the aerosol-forming material 33 are accommodated in the accommodating cavity 310. The heating element 32 includes a sensor material or is made of a sensor material, and is configured to generate heat in a magnetic field, to heat the aerosol-forming material 33.

[0516] The heating element 32 has a sheet-like structure (including a planar sheet-like structure and / or a non-planar sheet-like structure), and a specific shape thereof is not limited. It is set that the heating element 32 has a longitudinal direction Y1, a transverse direction Y2, and a transverse direction Y3 that are perpendicular to each other. The longitudinal direction Y1 is parallel to an axial direction of the container 31. When the heating element 32 is placed in the magnetic field, the longitudinal direction Y1 is further approximately parallel to a direction of the magnetic field. In some embodiments, the heating element 32 includes a heating main body 326. The heating main body 326 has a sheet-like structure and may be a geometric body formed by extending a geometrical surface along a direction. The extending direction may be parallel to an axis direction of the container 31 or form a preset angle.

[0517] Preferably, the heating main body 326 is partially exposed to the aerosol-forming material 33. In this way, during operation, the part of the heating main body 326 exposed to the aerosol-forming material 33 can rapidly heat up and atomize a part of liquid, which is beneficial to rapid smoke output. On the contrary, if the heating main body 326 is completely immersed in the liquid, the entire liquid can be atomized only after being heated, and it is difficult to achieve an objective of rapid smoke output. It should be noted that, in some embodiments, that the heating main body 326 is partially exposed to the aerosol-forming material 33 may include the following understanding: when the aerosol-forming material 33 is in a liquid state and in an initial state of being not heated, in a direction Y1, an upper end of the heating main body 326 is higher than a liquid level, and a lower end of the heating main body 326 is in contact with the bottom of the container 31. When the aerosol-forming material 33 is in a paste or aerogel state, because the aerosol-forming material 33 is relatively thick, the heating main body 326 is difficult to freely sink in the aerosol-forming material 33 in a state of being not heated. In the direction Y1, an upper portion of the heating main body 326 is exposed to the aerosol-forming material 33, and a lower portion of the heating main body 326 may be or not in contact with the bottom of the container 31. In a heated state, the viscosity of the aerosol-forming material 33 is reduced, and the heating main body 326 may freely sink. Therefore, when an aerosol is initially formed, an upper end of the heating main body 326 is higher than a liquid level, and a lower end of the heating main body 326 is in contact with the bottom of the container 31. To be specific, in the direction Y1, the entire height of the heating main body 326 is greater than a liquid height. However, when the heating main body 326 heats, if the entire heating main body 326 floats on the liquid only, an amount of smoke is relatively small, and it is difficult to satisfy user requirements.

[0518] In this embodiment, the heating main body 326 has a rectangular cross section, and the heating main body 326 is a rectangular sheet formed by extending a rectangular plane along an axial direction of the container 31. The heating element 32 may further include at least one leg 327 disposed at a lower end (an end away from the opening 311 in the longitudinal direction Y1) of the heating main body 326. The leg 327 is sheet-like and perpendicular to the axial direction of the container 31, which assists in placing the heating element 32 upright in the container 31, so that the heating element 32 can be in a standing state all the time under a magnetic field force. In addition, the leg 327 further assists in thoroughly heating the aerosol-forming material 33 at the bottom of the container 31, thereby reducing residues and achieving a high utilization rate. In addition, there is a magnetic convergence effect, thereby improving the atomization efficiency.

[0519] It is set that the transverse direction Y2 is a direction parallel to a short side of the cross section of the heating main body 326 and the transverse direction Y3 is a direction parallel to a long side of the cross section of the heating main body 326. In this embodiment, there are two legs 327. The two legs 327 are respectively disposed at two opposite sides of the heating main body 326 in the transverse direction Y2. In some embodiments, a total cross-sectional area of the two legs 327 occupies 20% or more than 20% of a cross-sectional area of a lower end of the accommodating cavity 310 (i.e. an end in which the legs 327 are accommodated, or an end away from the opening 311 in the longitudinal direction Y1), and is smaller than a cross-sectional area of a lower end of the accommodating cavity 310. This is beneficial to thoroughly heat the aerosol-forming material 33 at the bottom of the container 31, without being in contact with the side wall of the accommodating cavity 310 for a long time, thereby improving the atomization efficiency.

[0520] In some embodiments, a sealing film 351, such as an aluminum foil, may be further disposed at the opening 311 of the container 31. The sealing film 351 is configured to seal the opening 311, thereby preventing the aerosol-forming material 33 in the container 31 from flowing out, preventing external impurities from entering the container 31, and ensuring cleanness inside the container 31. During use, the sealing film 351 may be first torn off, to expose the opening 311. In other embodiments, the sealing film 351 may alternatively be pierced to expose the opening 311.

[0521] As shown in FIG. 80a and FIG. 80b, the heating element 32 may further include a heating layer 326a and a soaking layer 326b disposed on an outer surface of the heating layer 326a. The heating layer 326a includes a sensor material for generating heat in a magnetic field, for example, a ferromagnetic material. The thickness of the heating layer 326a may be 0.05 mm to 0.5 mm (including two end values), and is preferably 0.2 mm to 0.35 mm (including two end values). The soaking layer 326b has a thermal conductivity lower than that of the heating layer 326a. In some embodiments, the thermal conductivity of the soaking layer 326b is less than or equal to 10 W / m·K, preferably less than or equal to 3 W / m·K, facilitating even distribution of heat in the heating element 32. The soaking layer 326b may be made of a low thermal conduction non-metal material, such as glass enamel, ceramics, silicon carbide, silicon nitride, or a Teflon coating, and is preferably glass enamel. The thickness of the soaking layer 326b may be 5 um to 50 um (including two end values), and is preferably 10 um to 30 um (including two end values).

[0522] In an implementation shown in FIG. 80a, the soaking layer 326b is dense and smooth, and can effectively reduce the surface carbon deposition of the heating element 32. In an implementation shown in FIG. 80b, the soaking layer 326b is superficially porous, and can adsorb and conduct a liquid medium through the wetting and capillary effect of a porous micro-pore structure, thereby reducing dry heating and increasing the amount of smoke.

[0523] The heating element 32 may alternatively be bare magnetic. To be specific, the heating element 32 has only the heating layer 326a, and at least a part of the sensor material of the heating element 32 is exposed.

[0524] FIG. 81 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating main body 326 of the heating element 32 in this embodiment is has an arc-shaped cross section, and the heating main body 326 is an arc sheet formed by extending an arc surface along an axial direction of the container 31.

[0525] FIG. 82 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating main body 326 of the heating element 32 in this embodiment has a swirl (or helical) cross section. The heating element 32 having a swirl structure has a larger contact area between the heating element 32 and the aerosol-forming material 33, so that a large amount of smoke can be generated, and the aerosol-forming material 33 can be rapidly atomized.

[0526] Specifically, the heating main body 326 includes a plurality of ring-shaped unit sheets 3261, and a clearance space 3260 is formed between every two adjacent unit sheets 3261. The shape of each unit sheet 3261 includes, but is not limited to, a circular ring, an elliptic ring, a triangular ring, or a square ring.

[0527] The size of the clearance space 3260 is related to the viscosity of the aerosol-forming material 33. A lower viscosity of the aerosol-forming material 33 indicates a smaller clearance space 3260. A higher viscosity indicates a larger clearance space 3260, thereby effectively preventing a large-particle exploding liquid. In some embodiments, the size of the clearance space 3260 may be greater than 0 and less than or equal to 5 mm, and is preferably 0.2 mm to 2 mm (including two end values).

[0528] The size of the clearance space 3260 is relatively small. During heating, the aerosol-forming material 33 in the clearance space 3260 can boil and rush up by a distance, so that the aerosol-forming material 33 continuously flushes a wall surface of the heating element 32, thereby increasing a contact area between the heating element 32 and the aerosol-forming material 33, increasing the amount of smoke, and reducing poor inhaling feeling caused by dry heating. In addition, strong convective heat transfer can be formed between every two adjacent unit sheets 3261, so as to rapidly atomize the aerosol-forming material 33 in the clearance space 3260.

[0529] In some embodiments, the surface of the heating element 32 further has a particular degree of roughness, so that the aerosol-forming material 33 rushing up can naturally flow down after remaining on the surface of the heating element 32 for a period of time, thereby reducing dry heating and increasing the amount of smoke. However, it is not proper for the aerosol-forming material 33 to remain on the surface of the heating element 32 for a long time, and otherwise, carbon deposition is easily caused. In some embodiments, the surface roughness of the heating element 32 may range from Ra0.05 to Ra25 (including two end values), preferably, from Ra0.05 to Ra6.3 (including two end values). When the heating element 32 is provided with a soaking layer 326b, the surface roughness of the soaking layer 326b may range from Ra0.05 to Ra25 (including two end values), preferably from Ra0.05 to Ra6.3 (including two end values).

[0530] The surface of the heating element 32 further has a lyophilic property (including hydrophilia and / or lipophilicity), so that the aerosol-forming material 33 can rise along the surface of the heating element 32. A liquid level of the aerosol-forming material 33 in the clearance space 3260 is raised by a distance due to surface tension, thereby increasing a contact area between the aerosol-forming material 33 and the heating element 32, and improving the atomization efficiency and the amount of smoke.

[0531] In embodiments shown in FIG. 83 and FIG. 84, the heating main body 326 of the heating element 32 has an S-shaped or S-like cross section. The heating element 32 having an S-shaped or S-like structure also enables the heating element 32 to have a larger contact area with the aerosol-forming material 33, thereby generating a larger amount of smoke and achieving a higher atomization speed.

[0532] Specifically, the heating main body 326 includes a plurality of unit sheets 3261 spaced apart in the transverse direction Y3 and a connection sheet 3262 connected between every two adjacent unit sheets 3261. A clearance space 3260 is formed between every two adjacent unit sheets 3261. The size of the clearance space 3260 is relatively small. During heating, the aerosol-forming material 33 in the clearance space 3260 can boil and rush up by a distance, thereby increasing a contact area between the heating element 32 and the aerosol-forming material 33, increasing the amount of smoke, and reducing poor inhaling feeling caused by dry heating.

[0533] The size of the clearance space 3260 is related to the viscosity of the aerosol-forming material 33. A lower viscosity of the aerosol-forming material 33 indicates a smaller clearance space 3260. A higher viscosity indicates a larger clearance space 3260, thereby effectively preventing a large-particle exploding liquid. In some embodiments, the size of the clearance space 3260 may be less than or equal to 5 mm, and is preferably 0.2 mm to 2 mm (including two end values).

[0534] In an embodiment shown in FIG. 83, the unit sheets 3261 are parallel to each other, so that the size of the clearance space 3260 keeps unchanged in the transverse direction Y2.

[0535] In an embodiment shown in FIG. 84, every two adjacent unit sheets 3261 are disposed at an angle, so that the size of the clearance space 3260 is gradually increased or reduced in the transverse direction Y2.

[0536] It may be understood that in other embodiments, every two adjacent unit sheets 3261 may alternatively be directly connected to each other.

[0537] FIG. 85 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating main body 326 of the heating element 32 in this embodiment is has a major arc-shaped cross section, and the heating main body 326 is an arc sheet formed by extending a major arc plane along an axial direction of the container 31. The heating main body 326 having a major arc-shaped cross section may be better disposed upright in the container 31, so that a lower end of the heating main body 326 does not need to be provided with a leg 327.

[0538] An upper end of the heating main body 326 is open, to avoid dry heating during a heating process. A bottom wall may be disposed at a lower end of the heating main body 326 to cover an opening at a lower end thereof. The bottom wall enables the heating main body 326 to be better disposed upright in the container 31, and thoroughly heats the aerosol-forming material 33 at the bottom of the container 31, thereby reducing residues and achieving a high utilization rate. In addition, there is a magnetic convergence effect, thereby improving the atomization efficiency.

[0539] FIG. 86 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment has a twist shape and may be formed by twisting one or more heating substrates into a twist shape. Specifically, in this embodiment, the heating element 32 is formed by twisting a rectangular sheet-like heating substrate into a twist shape.

[0540] FIG. 87 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment includes a sheet-like heating main body 326 and at least one branch portion 328 disposed on at least one side of the heating main body 326.

[0541] Specifically, in this embodiment, the heating main body 326 is in a shape of a rectangular sheet. There are a plurality of branch portions 328. The plurality of branch portions 328 are respectively symmetrically disposed on two sides of the thickness of the heating main body 326, so that the heating element 32 has a fish-bone like shape as a whole.

[0542] It may be understood that in other embodiments, the plurality of branch portions 328 may be respectively disposed on two opposite sides of the heating main body 326 in a staggered mode, or the plurality of branch portions 328 may be disposed on a same side of the heating main body 326.

[0543] FIG. 88 to FIG. 90 show an aerosol-forming product 30 according to some embodiments of the present disclosure, including a container 31, and a heating element 32 and an aerosol-forming material 33 disposed in the container 31.

[0544] The heating element 32 has at least two surfaces 3216. At least one clearance space 3217 is formed between the at least two surfaces 3216. The clearance space 3217 extends along a longitudinal direction Y1 of the heating element 32. The pair of surfaces 3216 are oppositely disposed in a transverse direction Y2 of the heating element 32. The longitudinal direction Y1 and the transverse direction Y2 are perpendicular to each other. When the heating element 32 is placed in the container 31 for use, the longitudinal direction Y1 of the heating element 32 is parallel to an axial direction of the container 31 and is approximately parallel to a direction of a magnetic field. In addition, the heating element 32 further has a transverse direction Y3 perpendicular to both the longitudinal direction Y1 and the transverse direction Y2.

[0545] At least one end of the clearance space 3217 in the longitudinal direction Y1 of the heating element 32 has a first opening 321a, and / or at least one end of the clearance space 3217 in the transverse direction Y3 of the heating element 32 has a second opening 321b, so that the clearance space 3217 is communicated with the accommodating cavity 310 via the first opening 321a and / or the second opening 321b.

[0546] Further, the at least two surfaces 3216 further have a lyophilic property (including hydrophilia and / or lipophilicity), so that the aerosol-forming material 33 can rise along the surfaces 3216, and the liquid level is concave. The liquid level of the aerosol-forming material 33 in the clearance space 3217 is raised by a distance due to surface tension. In this way, a contact area between the aerosol-forming material 33 and the surfaces 3216 can be increased, the atomization efficiency is higher, and the amount of smoke is larger.

[0547] In some embodiments, the at least two surfaces 3216 include at least one pair of oppositely disposed surfaces 3216. A distance between the two oppositely disposed surfaces 3216 is relatively short, so that strong convective heat transfer is formed between the two surfaces 3216, so as to rapidly atomize the aerosol-forming material 33 in the clearance space 3217.

[0548] The size of a distance d1 between the two oppositely disposed surfaces 3216 is related to the viscosity of the aerosol-forming material 33. A lower viscosity of the aerosol-forming material 33 indicates a smaller d1. A higher viscosity indicates a larger d1, thereby effectively preventing a large-particle exploding liquid in the clearance space 3217. In addition, the distance d1 between the two surfaces 3216 may remain unchanged in the longitudinal direction Y1, or may have different sizes in the longitudinal direction Y1. Herein, d1 refers to the distance between the two oppositely disposed surfaces 3216 in the transverse direction Y2. In some embodiments, the range of d1 may be 0<d1≤5 mm, preferably 0<d1≤2 mm. The range of an inner diameter d2 of the container 31 may be 3 mm≤d2≤8 mm, preferably 4 mm≤d2≤6 mm.

[0549] The shape of each surface 3216 is not limited. For example, the surface may include a flat surface, a curved surface (such as an arc surface), or a combination of a flat surface and a curved surface.

[0550] Specifically, in this embodiment, the heating element 32 may include two heating side walls 321 oppositely disposed in the transverse direction Y2 of the heating element 32. The two oppositely disposed surfaces 3216 are formed by opposite surfaces of the two heating side walls 321. In this embodiment, the two heating side walls 321 both have a planar sheet-like structure. To be specific, each surface of the heating side wall 321 is planar. In addition, the two heating side walls 321 are disposed parallel to each other, so that the distance d1 between the two surfaces 3216 keeps unchanged in the longitudinal direction Y1.

[0551] When the container 31 is filled with the aerosol-forming material 33, the lowest liquid level of the aerosol-forming material 33 may be lower than an upper edge 321c of the heating element 32, so that the heating element 32 is partially exposed to the aerosol-forming material 33, facilitating rapid smoke output.

[0552] When the aerosol-forming material 33 includes a paste, because the paste is mostly solid at a room temperature, a relative position relationship between the aerosol-forming material 33 and the heating element 32 may be determined after the aerosol-forming material 33 is heated to a particular temperature (for example, greater than or equal to 75° C. and less than a boiling point) and liquefied.

[0553] Because the surface of the heating element 32 has a lyophilic property, a liquid level L2 between the two heating side walls 321 is higher than a liquid level L1 between the heating side wall 321 and the container 31. In some embodiments, the range of a distance Δd between the upper edge 321c of the heating element 32 and the liquid level L1 may be 0<Δd≤10 mm, preferably 0<Δd≤5 mm.

[0554] In some embodiments, the heating element 32 and the inner wall surface of the container 31 are at least partially spaced apart, so that a part of the aerosol-forming material 33 can be further filled in the clearance 3210 formed between the heating element 32 and the inner wall surface of the container 31, thereby further increasing a contact area between the aerosol-forming material 33 and the heating element 32. The clearance space 3217 may be communicated with the clearance 3210 through the first opening 321a and / or the second opening 321b, so that the aerosol-forming material 33 can flow between the clearance space 3217 and the clearance 3210.

[0555] In some embodiments, the heating element 32 includes a middle portion 32b and an upper portion 32a and a lower portion 32c respectively located at two ends of the middle portion 32b in the longitudinal direction Y1. An effective cross-sectional area of the upper portion 32a and an effective cross-sectional area of the lower portion 32c are both greater than an effective cross-sectional area of the middle portion 32b, which is beneficial to convergence of magnetic fields relatively dispersed at two ends, thereby improving utilization of the magnetic field. In addition, a relatively strong magnetic field is formed in the middle portion 32b by means of magnetic conduction of the heating element 32, so that more magnetic field lines are cut per unit area in the cross section of the middle portion 32b, thereby improving a temperature increasing speed of the middle portion 32b, reducing a preheat time, and improving energy utilization.

[0556] Herein, the “effective cross-sectional area” refers to a cross-sectional area of a part for transmitting a magnetic flux line in the heating element 32. Shaded parts (i.e. parts having section lines) in FIG. 90a, FIG. 90b, and FIG. 90c are respectively effective cross-sectional areas of the upper portion 32a, the lower portion 32c, and the middle portion 32b. In some embodiments, the effective cross-sectional area of the middle portion 32b may be 10% to 30% (including two end values) of the effective cross-sectional area of the upper portion 32a or the lower portion 32c. The effective cross-sectional areas of the upper portion 32a and the lower portion 32c may be equal or not equal. In other embodiments, the effective cross-sectional area of only one of the upper portion 32a and the lower portion 32c may be greater than the effective cross-sectional area of the middle portion 32b.

[0557] With reference to FIG. 89, in some embodiments, at least one protrusion portion 3215 is formed by protruding a side of the upper portion 32a and the lower portion 32c of each heating side wall 321 away from the other heating side wall 321, to increase the effective cross-sectional areas of the upper portion 32a and the lower portion 32c. The protrusion portion 3215 may further reduce a contact area between the heating element 32 and the container 31, thereby reducing a friction force, and making vibration of the heating element 32 more smooth. In addition, a positioning effect may be achieved, to prevent from causing uneven temperature or carbonization of a medium on the container 31 and causing bad inhaling feeling due to a large-area contact between the heating side wall 321 and the container 31.

[0558] Specifically, in this embodiment, two protrusion portions 3215 are formed by protruding from the upper portion 32a of each heating side wall 321. The two protrusion portions 3215 have a sheet shape and are respectively located at two sides of the transverse direction Y3 of the heating side wall 321. Two protrusion portions 3215 are also formed by protruding from the lower portion 32c of each heating side wall 321. The two protrusion portions 3215 have a sheet shape and are respectively located at two sides of the transverse direction Y3 of the heating side wall 321. In other embodiments, the quantity of the protrusion portions 3215 is not limited. In addition, the effective cross-sectional area of the middle portion 32b may be reduced by forming an opening in the middle portion 32b of the heating side wall 321.

[0559] Further, in this embodiment, the clearance space 3217 has a second opening 321b at two ends of the transverse direction Y3 of the heating element 32, and the clearance space 3217 has a first opening 321a at a top end (an end close to the opening 311) of the longitudinal direction Y1 of the heating element 32. The heating element 32 further includes a heating bottom wall 322 connecting the two heating side walls 321. The heating bottom wall 322 has a sheet shape, and may be connected to bottom ends of the two heating side walls 321 in the longitudinal direction Y1 and be disposed opposite to the first opening 321a. On one hand, the heating element 32 can be disposed upright in the container 31, and on the other hand, the effective cross-sectional area of the bottom of the heating element 32 can be further increased, facilitating further convergence of the magnetic field. In addition, the heating bottom wall 322 further assists in thoroughly heating the aerosol-forming material 33 at the bottom of the container 31, thereby reducing residues and achieving a high utilization rate.

[0560] In an embodiment shown in FIG. 91, a porous body 329 may further be disposed in the clearance space 3217 between the two heating side walls 321. The material of the porous body 329 may include ceramics, glass, graphites, or wool, and is preferably ceramics. The porous body 329 is freely placed in the clearance space 3217. The aerosol-forming material 33 is absorbed by the porous body 329 due to enhanced thermal fluidity. There is strong convective heat transfer between the two heating side walls 321, so as to rapidly atomize a medium absorbed by the porous body 329, increase the amount of smoke, and improve the inhaling feeling. In this embodiment, the porous body 329 is a porous sheet. The thickness of the porous sheet may be 0.5 mm to 3 mm (including two end values), and is preferably 0.8 mm to 1.5 mm (including two end values). In other embodiments, the form of the porous body 329 may include one or a combination of filament, particle, sheet, and the like.

[0561] In an embodiment shown in FIG. 92, the two heating side walls 321 are disposed at an angle, and the two surfaces 3216 of the two heating side walls 321 are planar and are disposed at an angle E relative to each other. In some embodiments, the range of the angle E may be 0<E≤30°. In addition, the bottom ends of the two heating side walls 321 are connected by using a heating bottom wall 322, so that a distance between the two surfaces 3216 is gradually increased from bottom to top. In addition, in this embodiment, only the upper portions of the two heating side walls 321 are provided with protrusion portions 3215, so as to increase the effective cross-sectional areas of the upper portions. In other embodiments, the distance between the two surfaces 3216 may be gradually reduced from bottom to top, and / or the protrusion portions 3215 may be disposed at the upper and lower portions of the two heating side walls 321.

[0562] FIG. 93 shows a heating element 32 according to some embodiments of the present disclosure. Compared with the embodiment shown in FIG. 92, in this embodiment, the bottom ends of the two heating side walls 321 are directly connected together. To be specific, a minimum distance between the two surfaces 3216 is zero, and the distance is gradually increased from bottom to top.

[0563] FIG. 94 shows a heating element 32 according to some embodiments of the present disclosure. Compared with the embodiment shown in FIG. 89, in this embodiment, the two heating side walls 321 each have an arc-shaped sheet shape. To be specific, two opposite surfaces of each heating side wall 321 in the transverse direction Y2 are arc surfaces. The two surfaces 3216 of the two heating side walls 321 are arc surfaces and axes thereof are parallel to each other. The bottom ends of the two heating side walls 321 are connected by using a sheet-like heating bottom wall 322. In addition, two peripheral sides of the upper portion and the lower portion of each heating side wall 321 extend outward along a peripheral direction to form a protrusion portion 3215, so as to increase the effective cross-sectional areas of the upper portion and the lower portion of the heating element 32.

[0564] In another implementation, the structure of the heating element 32 may be deformed. For example, axes of the two heating side walls 321 may be disposed at an angle. And / or, the bottom ends of two heating side walls 321 may be directly connected together. And / or, only the upper portion or the lower portion of the heating element 32 is provided with a protrusion portion 3215. And / or, a through hole or a through groove is provided in the heating side wall 321 in the middle of the heating element 32.

[0565] FIG. 95 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the embodiment shown in FIG. 89 lies in that in this embodiment, the heating element 32 includes two heating side walls 321 oppositely disposed in the transverse direction Y2 of the heating element 32, and at least one connection portion 3218 that is connected to the two heating side walls 321 and covers a part of the second opening 321b.

[0566] Similar to the embodiment shown in FIG. 89, the heating element 32 in this embodiment also includes a middle portion 32b and an upper portion 32a and a lower portion 32c respectively located at two ends of the middle portion 32b in the longitudinal direction Y1. In this embodiment, the upper portion 32a and the lower portion 32c of the heating element 32 are respectively provided with two connection portions 3218 oppositely disposed in the transverse direction Y3, so that the effective cross-sectional areas of the upper portion 32a and the lower portion 32c can be increased.

[0567] In this embodiment, the two heating side walls 321 have a planar sheet shape, and the two connection portions 3218 have an arc-shaped sheet shape, so that the upper portion 32a and the lower portion 32c have a runway-shaped cross section. In other embodiments, the heating side walls 321 and the connection portions 3218 may alternatively have other shapes. For example, the heating side walls 321 have an arc-shaped sheet shape, and / or, the connection portions 3218 have a planar sheet shape. In some other embodiments, the connection portion 3218 may alternatively be disposed only at the upper portion 32a or the lower portion 32c of the heating element 32.

[0568] In some embodiments, the upper portion 32a and the lower portion 32c of the heating element 32 may further be provided with protrusion portions 3215 protruding out of the clearance space 3217, thereby further increasing the effective cross-sectional areas of the upper portion 32a and the lower portion 32c. Specifically, in this embodiment, two ends of the upper portion 32a and the lower portion 32c of each heating side wall 321 in the transverse direction Y3 are respectively provided with a sheet-like protrusion portion 3215 protruding away from the other heating side wall 321. The protrusion portion 3215 further reduces a contact friction force between the heating element 32 and the container 31, thereby making vibration of the heating element 32 more smooth. In addition, a positioning effect may be achieved, to prevent from causing carbonization of a medium on the container 31 and causing bad inhaling feeling due to the contact between the heating side wall 321 and the container 31.

[0569] In addition, in this embodiment, the clearance space 3217 has a first opening 321a at two ends of the longitudinal direction Y1 of the heating element 32. In other embodiments, the lower ends of the two heating side walls 321 may also be provided with a heating bottom wall 322, to shield a part of the first openings 321a at the lower ends.

[0570] FIG. 96 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the embodiment shown in FIG. 89 lies in that in this embodiment, the heating element 32 includes four heating side walls 321 spaced apart in the peripheral direction. The four heating side walls 321 define a clearance space 3217.

[0571] Specifically, in this embodiment, each heating side wall 321 has a planar sheet shape, and the four heating side walls 321 are evenly spaced apart in the peripheral direction of the heating element 32, so as to form two pairs of oppositely disposed surfaces 3216. In other embodiments, each heating side wall 321 may alternatively have another shape such as an arc-shaped sheet.

[0572] In some embodiments, the heating element 32 may further include a heating bottom wall 322. The heating bottom wall 322 covers a lower opening of the clearance space 3217. The four heating side walls 321 may extend upward from a peripheral edge of the heating bottom wall 322. In other embodiments, the heating element 32 may alternatively not include the heating bottom wall 322.

[0573] FIG. 97 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the embodiment shown in FIG. 96 lies in that in this embodiment, the heating element 32 includes three heating side walls 321 evenly spaced apart in the peripheral direction, so as to form three surfaces 3216 evenly spaced apart in the peripheral direction of the heating element 32. A clearance space 3217 is defined in the three surfaces 3216.

[0574] FIG. 98 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 includes a plurality of cylindrical heating side walls 321 spaced apart in the peripheral direction of the heating element 32 and at least one connection portion 3218 connecting the plurality of heating side walls 321. A heating cavity 320 is defined in the plurality of heating side walls 321. Each heating side wall 321 may have a solid column shape or a hollow column shape.

[0575] In this embodiment, upper and lower ends of the heating cavity 320 are open. There are two connection portions 3218. The two connection portions 3218 are both annular and are respectively located at two axial ends of the plurality of heating side walls 321, which assists in improving a magnetic convergence effect at the two ends. In other embodiments, there may alternatively be one or more connection portions 3218. In addition, the connection portion 3218 may alternatively be disposed between two ends of the heating side wall 321.

[0576] FIG. 99 shows a heating element 32 according to some embodiments of the present disclosure. Different from the foregoing embodiments, upper and lower ends of the heating cavity 320 in this embodiment are sealed. Specifically, the two connection portions 3218 are both in a sheet shape and are respectively disposed at the upper and lower ends of the heating cavity 320, thereby sealing the upper and lower ends of the heating cavity 320.

[0577] FIG. 100 and FIG. 101 show a heating element 32 according to some embodiments of the present disclosure. The heating element 32 has a cellular shape, and has a plurality of through holes 320a formed through. Each through hole 320a extends through two axial ends of the heating element 32, and has functions of circulating airflow and accommodating the aerosol-forming material 33. Preferably, the through hole 320a is a capillary through hole having a capillarity force or a weak capillarity force. In other embodiments, the cross-sectional size of the through hole 320a may be relatively large, so as not to have a capillarity force.

[0578] FIG. 102 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment is in a shape of a hemispherical pot with a heating cavity 320 formed therein. An aerosol-forming material 33 may be accommodated in the heating cavity 320.

[0579] FIG. 103 shows a heating element 32 according to some embodiments of the present disclosure. In this embodiment, the heating element 32 has a cylindrical shape with an open upper end, and includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at a lower end of the heating side wall 321. A plurality of through holes 3220 are formed on the heating side wall 321. The plurality of through holes 3220 may be evenly spaced apart in an axial direction and / or a peripheral direction of the heating side wall 321. By providing the through holes 3220, an exploding liquid phenomenon that occurs after the aerosol-forming material 33 in the heating element 32 is heated can be effectively reduced, the surface of the heating element 32 can be more easily plated with an enamel layer in a process of enameling the heating element 32, thereby ensuring that the heating element 32 is uniformly plated with the enamel layer.

[0580] In other embodiments, the plurality of through holes 3220 may alternatively be formed on the heating bottom wall 322, or may be formed on both the heating side wall 321 and the heating bottom wall 322.

[0581] FIG. 104 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment has a shape of a tube with two open ends.

[0582] FIG. 105 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment includes a heating side wall 321 having a step-like shape. Specifically, the heating side wall 321 includes a first side wall 3211, a second side wall 3212, and a third side wall 3213 that are disposed in sequence from bottom to top along an axial direction. Inner diameters and outer diameters of the first side wall 3211, the second side wall 3212, and the third side wall 3213 are increased in sequence. In other embodiments, the shape of the heating side wall 321 may be randomly deformed. For example, the inner diameters and the outer diameters of the first side wall 3211, the second side wall 3212, and the third side wall 3213 may be gradually reduced. Alternatively, the inner diameter and the outer diameter of the second side wall 3212 are respectively greater than the inner diameters and the outer diameters of the first side wall 3211 and the third side wall 3213.

[0583] The lower end of the heating element 32 may have a heating bottom wall 322, or may not have a heating bottom wall 322.

[0584] FIG. 106 shows a heating element 32 according to some embodiments of the present disclosure. In this embodiment, the heating element 32 has a conical cylindrical shape with an open upper end, and includes a conical tubular heating side wall 321 and a heating bottom wall 322 disposed at a lower end of the heating side wall 321. Both an inner diameter and an outer diameter of the heating side wall 321 are gradually increased from bottom to top. In other embodiments, the inner diameter and the outer diameter of the heating side wall 321 may be gradually reduced from the bottom to the top.

[0585] FIG. 107 shows a heating element 32 according to some embodiments of the present disclosure. The heating element 32 in this embodiment has a shape of a conical tube with two open ends.

[0586] In some of the foregoing embodiments, the position of the heating element 32 in the container 31 may be relatively fixed or substantially fixed. For example, a limiting member is disposed to fix the heating element 32 in the container 31, or a protrusion is formed on the heating element 32 and / or the container 31 to position the heating element 32 in the container 31, so as to avoid sway of the heating element 32 in the container 31 during transportation or heating. In some embodiments, the heating element 32 may alternatively have a particular active space in the container 31. In this way, during a heating process, the viscosity of the aerosol-forming material 33 is reduced, and bubbles and magnetic force generated by the aerosol-forming material 33 can push the heating element 32 to move in the container 31, to implement a function of stirring the aerosol-forming material 33, so that the bubbles are rapidly collapsed to release a large amount of smoke, thereby implementing rapid atomization by using relatively small power. In addition, because the heating element 32 is not fixed in the container 31 and the heating element 32 may be taken out from the container 31, the heating element 32 may alternatively be used as a disposable consumable, thereby avoiding a problem of cleaning the heating element 32. In addition, the structure of the heating element 32 is simple and cheap, and replacement costs are relatively low. The entire container 31 may alternatively be replaced, thereby avoiding a problem of cleaning the container 31.

[0587] FIG. 108 and FIG. 109 show an aerosol-forming product 30 according to some embodiments of the present disclosure, including a container 31, and a heating element 32 and an aerosol-forming material 33 disposed in the container 31.

[0588] In this embodiment, the heating element 32 is in a shape of a container, a heating cavity 320 is formed therein, and an aerosol-forming material 33 may be disposed in the heating cavity 320. Specifically, the heating element 32 includes a tubular heating side wall 321 and a heating bottom wall 322 disposed at an axial end of the heating side wall 321. In other embodiments, the heating side wall 321 may alternatively have or approximately have another tube shape such as an elliptic tube shape, a runway-shaped tube shape, a square tube shape, or a polygonal tube shape.

[0589] In addition, in this embodiment, the heating element 32 has an even or approximately even thickness. Specifically, the heating side wall 321 and the heating bottom wall 322 have the same or approximately the same thickness. In other embodiments, the heating side wall 321 and / or the heating bottom wall 322 may alternatively have an uneven wall thickness.

[0590] A clearance 3210 is formed between an outer wall surface (a surface radially away from the heating cavity 320) of the heating element 32 and an inner wall surface (a surface radially close to the heating cavity 320) of the container 31, so that the heating element 32 has a particular active space in the container 31, and a large-area contact between the outer wall surface of the heating element 32 and the inner wall surface of the container 31 is reduced. The heating element 32 is further provided with a through hole 3220. During heating, the aerosol-forming material 33 in the heating element 32 can flow to the clearance 3210 through the through hole 3220.

[0591] According to a first aspect, the aerosol-forming material 33 flowing into the clearance 3210 can be in contact with the outer wall surface of the heating element 32, so that a contact area between the aerosol-forming material 33 and the heating element 32 is increased, thereby increasing the amount of smoke. In addition, because there is a relatively small quantity of the aerosol-forming material 33 in the clearance 3210, the temperature rises more rapidly, facilitating rapid smoke output. According to a second aspect, as shown in FIG. 109, a relatively small clearance 3210 may enable the aerosol-forming material 33 in the clearance 3210 to boil and rush up by a distance, so that the aerosol-forming material 33 continuously flushes a wall surface of the heating element 32, thereby increasing a contact area between the outer wall surface of the heating element 32 and the aerosol-forming material 33, increasing the amount of smoke, and reducing poor inhaling feeling caused by dry heating. According to a third aspect, as shown in FIG. 110, bubbles 330 generated in the heating process of the aerosol-forming material 33 in the clearance 3210 can push the heating element 32 to move in the container 31, to implement a function of stirring the aerosol-forming material 33, so that the bubbles 330 are rapidly burst to release a large amount of smoke by stirring, thereby implementing rapid atomization by using relatively small power. According to a fourth aspect, by providing the through holes 3220, an exploding liquid phenomenon that occurs after the aerosol-forming material 33 in the heating element 32 is heated can be reduced.

[0592] The surface of the heating side wall 321 of the heating element 32 has a particular degree of roughness, so that the aerosol-forming material 33 rushing up can naturally flow down after remaining on the surface of the heating side wall 321 for a period of time, thereby reducing dry heating and increasing the amount of smoke. However, it is not proper for the aerosol-forming material 33 to remain on the surface of the heating side wall 321 for a long time, and otherwise, carbon deposition is easily caused. In some embodiments, the surface roughness of the heating side wall 321 may range from Ra0.05 to Ra25 (including two end values), preferably, from Ra0.05 to Ra6.3 (including two end values). When the heating element 32 is provided with a soaking layer 326b, the surface roughness of the soaking layer 326b may range from Ra0.05 to Ra25 (including two end values), preferably from Ra0.05 to Ra6.3 (including two end values).

[0593] There may be one or more through holes 3220. The shape of the through hole 3220 may be any regular or irregular shape such as a circle, an ellipse, a triangle, or a polygon, and is preferably a circle or an ellipse. The through hole 3220 may be provided in the heating side wall 321 and / or the heating bottom wall 322. As shown in FIG. 108, in this embodiment, the through hole 3220 is circular and is provided in the heating bottom wall 322. A hole diameter d5 of the through hole 3220 may be 0.5 mm to 3 mm (including two end values), and is preferably 0.8 mm to 1.5 mm (including two end values).

[0594] The size of the clearance 3210 is related to the viscosity of the aerosol-forming material 33. In some embodiments, a size d4 of the clearance 3210 may be 0<d4≤5 mm, preferably 0.2 mm≤d4≤2 mm. An outer diameter d3 of the heating element 32 may be 2.5 mm to 6 mm (including two end values), and is preferably 3.5 mm to 5 mm (including two end values). An inner diameter d2 of the container 31 may be 4 mm to 10 mm (including two end values), and is preferably 5.5 mm to 8 mm (including two end values). Herein, the size d4 of the clearance 3210 refers to a distance between the outer wall surface of the heating element 32 and the inner wall surface of the container 31 when the heating element 32 and the container 31 are coaxially disposed.

[0595] FIG. 111 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that in this embodiment, a through hole 3220 is provided in the heating side wall 321. Preferably, the through hole 3220 is provided at a position of the heating side wall 321 close to the heating bottom wall 322, so that in most processes of being consumed because of heating, the aerosol-forming material 33 can flow out through the through hole 3220. In some embodiments, a distance h between a center line of the through hole 3220 and the bottom surface of the heating element 32 may be less than or equal to 6 mm, preferably 0<h≤3 mm.

[0596] FIG. 112 and FIG. 113 show a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that an inner wall surface of the heating side wall 321 of the heating element 32 in this embodiment is a smooth surface, and an outer wall surface of the heating side wall 321 is convex-concave, so that the wall thickness of the heating side wall 321 is uneven. On one hand, the convex-concave outer wall surface can reduce time in which the aerosol-forming material 33 remains on the outer wall surface of the heating side wall 321, thereby reducing dry heating and improving the amount of smoke. On the other hand, the contact area between the container 31 and the heating element 32 when being pushed by the bubbles to move can be reduced, facilitating to reduce the amount of heat transferred by the heating element 32 to the container 31.

[0597] Specifically, in this embodiment, the heating side wall 321 may include a tubular body 321e and a plurality of ribs 321f extending outward from an outer wall of the tubular body 321e. The tubular body 321e has a circular tube shape, the plurality of ribs 321f are evenly spaced apart in a peripheral direction of the tubular body 321e, and each rib 321f extends vertically downward from an upper end surface of the tubular body 321e to a lower end surface. The ribs 321f extend along a vertical direction, facilitating flow of the aerosol-forming material 33. In other embodiments, the tubular body 321e alternatively has another shape such as an elliptic tube, a square tube, or a polygonal tube.

[0598] A plurality of convex surfaces 321g are formed on outer wall surfaces of the plurality of ribs 321f, and a plurality of convex surfaces 321h are formed on an outer wall surface of a part of the tubular body 321e located between every two adjacent ribs 321f. The plurality of convex surfaces 321g and the plurality of convex surfaces 321h are alternately distributed one by one in the peripheral direction of the heating side wall 321, and the convex surfaces 321g are closer to the inner wall surface of the container 31 in a radial direction than the convex surfaces 321h are. When the heating element 32 is pushed to move by the bubbles, the convex surfaces 321g of the heating element 32 are in contact with the inner wall surface of the container 31, but the convex surfaces 321h are not in contact with the inner wall surface of the container 31, thereby greatly reducing a contact area with the container 31.

[0599] FIG. 114 and FIG. 115 show a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the heating side wall 321 of the heating element 32 in this embodiment has a special-shaped tube shape, and an inner wall surface and an outer wall surface of the heating side wall 321 are both convex-concave, so that the wall thickness of the heating side wall 321 is even or approximately even.

[0600] Specifically, in this embodiment, the heating side wall 321 includes a plurality of convex portions 321j and a plurality of convex portions 321k that are alternately distributed in a peripheral direction. The plurality of convex portions 321j and the plurality of convex portions 321k are connected to form the heating side wall 321 having an even or approximately even wall thickness. Outer wall surfaces of the plurality of convex portions 321j form a plurality of convex surfaces 321g, and outer wall surfaces of the plurality of convex portions 321k form a plurality of concave surfaces 321h. The plurality of convex surfaces 321g and the plurality of convex surfaces 321h are alternately distributed one by one in the peripheral direction of the heating side wall 321, and the convex surfaces 321g are closer to the inner wall surface of the container 31 in a radial direction than the convex surfaces 321h are. When the heating element 32 is pushed to move by the bubbles, the convex surfaces 321g of the heating element 32 are in contact with the inner wall surface of the container 31, but the convex surfaces 321h are not in contact with the inner wall surface of the container 31, thereby greatly reducing a contact area with the container 31.

[0601] More specifically, in this embodiment, connection lines of cross-sectional contours of the plurality of convex portions 321j form a tubular structure. Every two convex portions 321j are connected to each other by using one convex portion 321k, and the convex portion 321k has an arc shape and is recessed into the heating cavity 320.

[0602] FIG. 116 shows a heating element 32 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that a plurality of positioning legs 321m are formed by protruding outward from the heating side wall 321 of the heating element 32 in this embodiment. The plurality of positioning legs 321m may be spaced apart in an axial direction and / or a peripheral direction of the heating side wall 321. Specifically, in this embodiment, the plurality of positioning legs 321m may be integrally formed by extending outward from the upper end of the heating side wall 321, and may be evenly spaced apart in the peripheral direction of the heating side wall 321, which is beneficial to even stressing, and is beneficial to convergence of relatively dispersed magnetic fields at the upper end. The plurality of positioning legs 321m can prevent the heating side wall 321 from being in contact with the container 31 for a long time, thereby greatly reducing the amount of heat transferred by the heating element 32 to the container 31, and preventing from causing carbonization of a medium on the container 31 and causing bad inhaling feeling due to an over-high temperature of the container 31. Preferably, the quantity of the positioning legs 321m may be 3 to 8, to facilitate processing and manufacturing. In other embodiments, only one positioning leg 321m may alternatively be provided. In some other embodiments, the positioning leg 321m may alternatively be disposed at any other position such as the lower end or the middle portion of the heating side wall 321.

[0603] FIG. 117 and FIG. 118 show an aerosol-forming product 30 according to some embodiments of the present disclosure. A main difference from the foregoing embodiments lies in that the aerosol-forming product 30 in this embodiment further includes a limiting member 34 sleeved on the heating element 32. The limiting member 34 includes at least one limiting leg 345. The at least one limiting leg 345 may prevent the heating side wall 321 from being in contact with the container 31 for a long time, thereby greatly reducing the amount of heat transferred by the heating element 32 to the outside.

[0604] Specifically, in this embodiment, the limiting member 34 is sleeved at the upper end of the heating element 32, and may include an annular body 346 sleeved around the heating side wall 321, at least one limiting leg 345 protruding outward from the annular body 346, and at least one inner flange 347 protruding inward from the annular body 346. The at least one inner flange 347 may abut against an upper end surface of the heating side wall 321, to implement axial positioning of the limiting member 34.

[0605] Preferably, there are a plurality of limiting legs 345 and a plurality of inner flanges 347. The plurality of limiting legs 345 and the plurality of inner flanges 347 are evenly spaced apart in a peripheral direction of the annular body 346.

[0606] In one embodiment, the limiting member 34 implements limiting by contact between the plurality of limiting legs 345 and the container 31. An inner diameter of the annular body 346 may be greater than an outer diameter of the heating side wall 321, so that a clearance exists between an inner wall surface of the annular body 346 and an outer wall surface of the heating side wall 321, and the heating element 32 may move within a range restricted by the annular body 346.

[0607] In another embodiment, there may be no clearance between the annular body 346 and the heating side wall 321. For example, the annular body 346 and the heating side wall 321 are riveted and f...
