[0002] An aerosol generating device is a device that can generate aerosol from a smoking product.

[0003] In the related art, the aerosol generating device includes a mouthpiece, a heating element, an airway tube and a container for containing tobacco products. The heating element is used to heat the tobacco products so that the tobacco products generate aerosols. The mouthpiece is connected to the container through the airway tube fluid. However, only part of the smoke generated by the tobacco products will flow into the mouthpiece along the airway tube, and the rest will flow and condense outside the airway tube, thereby sticking to the components arranged between the mouthpiece and the container, which will not only affect the realization of some functions of the aerosol generating device, but also lead to a reduction in the smoke of a puff, affecting the smoking taste.

[0068] Please refer to Figures 1 to 3 One embodiment of the present application provides an aerosol generating device, which is a device that can be connected to an aerosol generating substrate 1 and can interact with the aerosol generating substrate 1 to make the aerosol generating substrate 1 generate aerosol.

[0069] Aerosol formation substrate 1 is a kind of material that can produce aerosol under the effect of ultrasonic wave, microwave and temperature rise.Aerosol formation substrate 1 can be the volatile compound that intention is heated rather than burning to release to form aerosol.Aerosol formation substrate 1 can be solid form, for example can be the integrated thing that tobacco shred, tobacco leaf or cigarette particle phase gather and form.Aerosol formation substrate 1 can comprise tobacco-containing material, and described tobacco-containing material contains the volatile tobacco flavor compound that releases from described substrate when heating, or described tobacco-containing material is the material that contains nicotine.Aerosol formation substrate 1 can comprise containing non-tobacco material.Aerosol formation substrate 1 can contain tobacco-containing material and non-tobacco material simultaneously.

[0070] The aerosol generating device comprises a first component 2 and a second component 3. The second component 3 comprises a mouthpiece 31, at least part of which can be held in the mouth of a user, and the user inhales the aerosol generated by the aerosol generating substrate 1 in the aerosol generating device into the oral cavity by holding and sucking the mouthpiece 31. The first component 2 comprises a housing 21, and the housing 21 has a second receiving cavity 221 for receiving at least part of the aerosol generating substrate 1. The first component 2 also comprises an excitation element capable of causing the aerosol generating substrate 1 to generate an aerosol. In one embodiment, the excitation element comprises a heating component 22, and the heating component 22 heats the aerosol generating substrate 1 by releasing heat, so that the aerosol generating substrate 1 generates an aerosol.

[0071] In order to prevent the aerosol generated by the aerosol generating substrate 1 from being too hot to burn the mouthpiece under the heat released by the heating component, when the first component 2 and the second component 3 are connected, the suction nozzle 31 and the second receiving chamber 221 are arranged at a distance, so that the airflow channel connecting the suction nozzle 31 and the second receiving chamber 221 has a large length, so that the aerosol can dissipate heat more fully when flowing along the airflow channel. Based on this, in one embodiment, it can be referred to Figure 1-Figure 3 The first component 2 also has a first receiving chamber 211 in the housing 21. When the first component 2 is coupled with the second component 3, at least a portion of the first receiving chamber 211 is located between the suction nozzle 31 and the second receiving chamber 221. The second component 3 also includes an airway tube 32. The airway tube 32 has an airway therein, which constitutes at least a portion of the airflow channel, so that the airway tube 32 can fluidically connect the suction nozzle 31 and the second receiving chamber 221. At least a portion of the airway tube 32 is received in the first receiving chamber 211, so that at least a portion of the airway tube 32 is disposed between the suction nozzle 31 and the second receiving chamber 221, so that the suction nozzle 31 and the second receiving chamber 221 are spaced apart.

[0072] The aerosol-forming substrate 1 is removably connected to the first component 2, so that the aerosol-forming substrate 1 in the first component 2 can be replaced, so that the first component 2 can be used repeatedly, thereby reducing the use cost of the aerosol generating device.

[0073] In the first aspect of the present application, in the provided aerosol generating device, the second component 3 also includes a pushing portion 33. After the first component 2 is engaged with the second component 3, the pushing portion 33 can move from a first position to a second position along a first direction relative to the housing 21 of the first component 2, wherein the second position is located in the second receiving cavity 221, or the first position and the second position are located on opposite sides of the second receiving cavity 221, so that in the process of the pushing portion 33 of the second component 3 moving along the first direction to the second position, the pushing portion 33 can squeeze the aerosol generating matrix 1 located in the second receiving cavity 221, and compact the relatively loose aerosol generating matrix 1 in the second receiving cavity 221, or can push at least a part of the aerosol generating matrix 1 out of the second receiving cavity 221, so as to facilitate the user to take out the aerosol generating matrix 1 from the first component 2.

[0074] Based on the first aspect, in one embodiment, see Figure 1-Figure 3 and Figure 6 , the aerosol generating device also includes an elastic component 4, which can support the second component 3 so that the push part 33 can be maintained in the first position and prevent the push part 33 from moving from the first position to the second position. Specifically, the deformation of the elastic component 4 is linked to the displacement of the push part 33, that is, the deformation direction and deformation amount of the elastic member 42 in the elastic component 4 follow the displacement direction and displacement amount of the push part 33. When the push part 33 is in the first position, the elastic component 4 supports or pulls the second component 3 to prevent the push part 33 from moving to the second position. When the push part 33 is in the second position, the elastic component 4 supports or pulls the second component 3 so that the push part 33 can automatically move from the second position to the first position. Among them, the deformation direction of the elastic component 4 can be roughly parallel to the first direction, or the elastic component 4 can be elastically deformed roughly along the first direction.

[0075] As an example, see Figure 6, the second component 3 includes a moving component and a positioning component A. The positioning component A can be connected to the first component 2, or after the first component 2 is engaged with the second component 3, the positioning component A can remain relatively still in the first direction relative to the first component 2. The moving component can move relative to the positioning component A, wherein the pushing portion 33 is a component of the moving component. Therefore, after the second component 3 is engaged with the first component 2, the moving component in the second component 3 can be driven to move, so that the pushing portion 33 moves from the first position to the second position relative to the positioning component A. In this example, the moving component includes a nozzle 31 and an airway tube 32, and a pushing portion 33 is connected to the airway tube 32, and the nozzle 31, the airway tube 32 and the pushing portion 33 are arranged in linkage; the elastic component 4 is arranged in the second component 3, or when the pushing portion 33 is in the second position, one end of the elastic component 4 is connected to the positioning component A, and the other end is connected to the moving component, such as the nozzle 31, and the elastic component 4 has elastic deformation between the positioning component A and the moving component, so that the moving component can automatically reset to the first position; or in this example, when the pushing portion 33 is in the first position, the elastic component 4 can support the moving component so that the pushing portion 33 can remain in the first position. Figure 6 In the illustrated embodiment, the first component 2 further includes a first magnetic member 23, and the moving component further includes a second magnetic member A1, which is held on the positioning component A. When the first component 2 and the second component 3 are engaged, the first magnetic member 23 and the second magnetic member A1 are magnetically attracted to each other, so that the first component 2 and the second component 3 can remain connected, preventing the user from taking the second component 3 away from the first component 2 when holding the nozzle 31. The first component 2 also includes a support platform 24, which supports the positioning component A to prevent the positioning component A from moving along the first direction with the moving component.

[0076] As an example, see Figure 1-Figure 3 When the first component 2 is coupled with the second component 3 , the elastic component 4 is disposed between the first component 2 and the second component 3 , so that the second component 3 as a whole can move relative to the first component 2 .

[0077] The elastic component 4 is disposed in the first receiving cavity 211 , so that at least a portion of the elastic component 4 is located between the suction nozzle 31 and the second receiving cavity 221 .

[0078] In one embodiment, reference may be made to Figure 1-Figure 3The elastic component 4 includes an elastic member 42 and a movable seat 41 that can move relative to the housing 21 of the first component 2. The movable seat 41 is connected to the second component 3, and the displacement of the movable seat 41 is linked to the displacement of the pushing portion 33. The elastic member 42 is connected to the movable seat 41, so the deformation of the elastic member 42 is linked to the displacement of the movable seat 41. When the pushing portion 33 is located at the first position and / or the second position, the elastic member 42 can keep supporting or pulling the movable seat 41, so that the elastic component 4 keeps supporting or pulling the second component 3.

[0079] The elastic component 4 can constitute a module independent of the first component 2 and / or the second component 3, so as to facilitate the elastic component 4 to be joined and separated from the first component 2, or to facilitate the elastic component 4 to be joined and separated from the second component 3. Figure 1-Figure 3 The elastic component 4 also includes a retaining seat 43. One end of the elastic member 42 is connected to the moving seat 41, and the other end is connected to the retaining seat 43. Further, the retaining seat 43 may include a first side wall 431 that is slidably connected to the moving seat 41. When the elastic member 42 is deformed, the moving seat 41 may slide along the first side wall 431. The first side wall 431 can prevent the elastic member 42 from twisting when it is deformed. The retaining seat 43 may also include a second side wall 432. When the pushing portion 33 is in the first position, it can be referred to Figure 1 and Figure 3 , the second side wall 432 is spaced apart from the movable seat 41; when the pushing portion 33 is located at the second position, Figure 2 The second side wall 432 abuts against the moving seat 42 to prevent the moving seat 42 from continuing to move along the original moving direction.

[0080] As an example, the first side wall 431 and the second side wall 432 are spaced apart in the radial direction, and a part of the elastic member 42 can be kept between the first side wall 431 and the second side wall 432. Figure 1-Figure 3 In the illustrated embodiment, the first sidewall 431 is disposed around the periphery of the second sidewall 432. In other examples, the second sidewall 432 is disposed around the periphery of the first sidewall 431.

[0081] As an example, see Figure 1-Figure 3 A guide rail 433 is provided on one of the retaining seat 43 and the moving seat 41, and a slider 411 is provided on the other. When the pushing portion 33 moves from the first position to the second position, the slider 411 slides along the guide rail 433. When the guide rail 411 extends along the first direction, the slider 411 slides along the guide rail 433 to prevent the moving seat 41 from rotating.

[0082] Based on the first aspect, in one embodiment, reference may be made to Figure 1 and Figure 2The suction nozzle 31 is linked with the push portion 33. When the position of the push portion 33 changes, the position of the suction nozzle 31 changes accordingly. When the push portion 33 is in the first position, Figure 1 , at least part of the nozzle 31 is exposed outside the housing 21 for user operation; when the pushing portion 33 is in the second position, the suction nozzle 31 can be referred to Figure 2 , at least part of the suction nozzle 31 is located in the first receiving cavity 211. The user can drive the push portion 33 to move from the first position to the second position along the first direction by pressing the suction nozzle 31. Of course, in other embodiments, the user can also drive the push portion 33 to move from the first position to the second position along the first direction by operating other exposed parts of the second component 3 except the suction nozzle 31.

[0083] For further information, please refer to Figure 1 and Figure 2 The movable seat 41 supports the suction nozzle 31, so that the suction nozzle 31 can move with the movable seat 41, so that the suction nozzle 31 is linked with the pushing portion 33. When the pushing portion 33 is located at the first position, the movable seat 41 supports the suction nozzle 31 and keeps at least a part of the suction nozzle 31 outside the shell 21. When the pushing portion 33 is located at the second position, the elastic member 42 is deformed so that the first receiving cavity 211 produces a make way space, so that at least a part of the suction nozzle 31 is received in the first receiving cavity 211.

[0084] In the second aspect of the present application, in the provided aerosol generating device, the first component 2 is detachably connected to the second component 3, and the second component 3 can be removed from the first component 2 to clean the second component 3 and / or the first receiving chamber 211, or to replace at least part of the second component 3.

[0085] Based on the second aspect, in one embodiment, the second component 3 is configured to be detachable from the first component 2 along a second direction, wherein the first direction is opposite to the second direction.

[0086] In one embodiment, the aerosol generating device provided by the second aspect has the characteristics and properties of any one or more embodiments and examples provided by the first aspect, and the first component 2 and the second component 3 are detachably connected and can be combined, interact and interact with the characteristics and properties of any one or more embodiments provided by the first aspect.

[0087] For example, the second component 3 may be detachably connected to the elastic component 4. Further, the movable seat 41 in the elastic component 4 is detachably connected to the second component 3, and when the movable seat 41 supports the suction nozzle 31, the movable seat 41 is detachably connected to the suction nozzle 31.

[0088] Specifically, the detachable connection between the movable seat 41 and the second component 3 includes a screw-on connection between the movable seat 41 and the second component 3. Figure 3 , the moving seat 41 is provided with an L-shaped groove 412, and the suction nozzle 31 is provided with a protrusion 311. First, the protrusion 311 is made to slide along the vertical groove in the L-shaped groove 412, and then the suction nozzle 31 is rotated, and then the protrusion 311 is made to slide along the horizontal groove in the L-shaped groove 412. Therefore, the protrusion 311 is engaged with the L-shaped groove 412. The interference between the protrusion 311 and the horizontal groove can prevent the suction nozzle 31 from detaching from the moving seat 41, so that the first component 2 and the second component 3 remain connected. The slider 411 between the moving seat 41 and the retaining seat 43 cooperates with the guide rail 433 to prevent the moving seat 41 from rotating when it is linked with the push part 33, so as to prevent the first component 2 from being separated from the second component 3 when the push part 33 moves in the first direction and the second direction.

[0089] Alternatively, the detachable connection between the movable seat and the second component 3 includes a magnetic connection between the movable seat 41 and the second component 3. Alternatively, the detachable connection between the movable seat 41 and the suction nozzle 31 includes a threaded connection between the movable seat and the second component.

[0090] Based on the second aspect, in one embodiment, reference may be made to Figure 1-Figure 5 , the airway tube 32 is connected to the pushing part 33, and the pushing part 33 is arranged on the distal end of the airway tube 32, so that the airway tube 32 and the pushing part 33 are arranged in linkage. One or more air holes 331 may be provided on the pushing part 33 to fluidically connect the second receiving cavity 221 and the airway tube 32. At the same time, the air holes 331 provided on the pushing part 33 can prevent the fragments, particles or leaves of the aerosol generating matrix 1 from entering the airway tube 32, which can prevent the airway tube 32 from being blocked and prevent the user from sucking solid substances such as fragments, particles or leaves of the aerosol generating matrix 1 into the oral cavity.

[0091] During at least part of the travel of the push portion 33 from the first position to the second position, the push portion 33 may contact the aerosol generating substrate 1. In order to prevent the aerosol generating substrate 1 from adhering to the push portion 33 and blocking the pores 331, or to prevent the viscous or solid matter formed by the condensation of the aerosol on the push portion 33 from blocking the pores 331, the push portion 33 may be cleaned after the second component 3 is removed from the first component 2. In one embodiment, the push portion 33 is detachably connected to the airway tube 32, so that the push portion 33 can be taken out and then cleaned, or the push portion 33 can be replaced. Of course, in other embodiments, the push portion 33 can be integrally formed with the airway tube 32.

[0092] The pushing portion 33 may be made of metal, ceramic or plastic.

[0093] In one embodiment, reference may be made to Figure 1-Figure 5 The second component 3 further includes a liquid absorbent cotton 34, which is disposed in the suction nozzle 31, or in the airway tube 32, or partially in the airway tube 32 and partially in the suction nozzle 31. The liquid absorbent cotton 34 is used to absorb the condensed liquid in the suction nozzle 31 or the airway tube 32 to prevent the user from sucking the condensed liquid into the oral cavity.

[0094] It should be noted that the aerosol generating device provided in the second aspect having the features and properties of any one or more embodiments provided in the first aspect is optional and not mandatory, and at least some features or structures of the second aspect may be independent of the first aspect.

[0095] In the third aspect of the present application, the provided aerosol generating device also includes a sealing component, wherein the sealing component 5 is connected to the airway tube 32 in the second component 3, and the first receiving chamber 211 and the second receiving chamber 221 are isolated from each other and arranged on opposite sides of the sealing component 5, so that the sealing component 5 can promote the aerosol formed in the second receiving chamber 221 to enter the mouthpiece 31 through the airway tube 32, and can prevent the aerosol from entering the first receiving chamber 211, so as to keep the first receiving chamber 211 clean, and avoid affecting the performance and function of the components arranged in the first receiving chamber 211 (for example, avoiding the viscous matter formed by the condensation of the aerosol from adhering to the outer wall of the elastic component 4 and / or the airway tube 32, thereby corroding the elastic member 42 or affecting the elastic deformation of the elastic component 4 or affecting the movement of the airway tube 32 relative to the outer shell 21, etc.), and also helps to concentrate the formed aerosol on the mouthpiece 41, which is beneficial for improving the fullness and taste of a puff.

[0096] Based on the third aspect, in one embodiment, the aerosol generating device provided by the third aspect may have the characteristics and properties of any one or more embodiments provided by the first aspect and / or the second aspect, and the above-mentioned sealing component may be combined, interact and interact with the characteristics and properties of any one or more embodiments provided by the first aspect and / or the second aspect.

[0097] Example 1: You can refer to Figure 1-Figure 3, the sealing component 5 is retained in the housing 21, one end of the elastic component 4 is connected to the sealing component 5, and the other end is connected to the second component 3. As an example, one end of the elastic member 42 in the elastic component 4 is connected to the moving seat 41, and the other end of the elastic member 42 is connected to the sealing component 5. As an example, the elastic component 4 includes a moving seat 41, an elastic member 42 and a retaining seat 43, the opposite ends of the elastic member 42 are respectively connected to the moving seat 41 and the retaining seat 43, the moving seat 41 is connected to the second component 3, and is arranged in linkage with the pushing portion 33, and the sealing component 5 supports the retaining seat 43; further, the connection between the sealing component 5 and the retaining seat 43 can be a detachable connection, and the connection between the sealing component 5 and the retaining seat 43 can be a chimeric connection or a snap-on connection to prevent the two from rotating relative to each other.

[0098] Example 2: You can refer to Figure 1-Figure 3 and Figure 7 The sealing component 5 is fixed in the housing 21. When the first component 2 can be detachably connected to the second component 3, the second component 3 is detachably connected to the sealing component 5, so that when the second component 3 is removed from the first component 2, the second component 3 is also separated from the sealing component 5, and the sealing component 5 can continue to remain in the housing 21.

[0099] Furthermore, during the process of the pushing portion 33 moving along the first direction, the pushing portion 33 moves relative to the sealing assembly 5. When the airway tube 32 and the pushing portion 33 are arranged in linkage, as the pushing portion 33 moves along the first direction, the airway tube 32 can remain connected to the sealing assembly 5 and the connection between the airway tube 32 and the sealing assembly 5 is a sliding connection, so that the sealing performance of the connection between the airway tube 32 and the sealing assembly 5 is not affected.

[0100] In such Figure 1-Figure 3 and Figure 7 In the embodiment, the heating assembly 22 includes a heating tube 222, at least a portion of the second receiving cavity 221 is disposed in the heating tube 222, and the sealing assembly 5 includes a flexible member 51, which seals and connects the airway tube 32 and the heating tube 222. The flexible member 51 may be silicone, rubber, or sponge, etc., which is at least partially disposed between the heating tube 222 and the airway tube 32, and elastically abuts against the heating tube 222 and the airway tube 32, thereby preventing aerosol from passing between the heating tube 222 and the airway tube 32. Specifically, the flexible member 51 may include a hollow tube, in which a portion of the airway tube 32 is located and has an interference fit with the hollow tube, and the airway tube 32 can move relative to the flexible member 51 along the axis of the hollow tube. The hollow tube can extend to surround a portion of the heated tube 222 or extend to surround a portion of the heating tube 222, and be arranged close to the inner wall of the heating tube 222 or close to the outer wall of the heating tube 222, thereby achieving a sealed connection between the heating tube 222 and the airway tube 32.

[0101] In order to reduce power consumption, the heating assembly 22 may further include an insulating tube 223 disposed around the heating tube 222, and the insulating tube 223 is used to prevent heat from being lost radially outward, so that the heat can be concentrated and maintained in the second receiving cavity 221. The insulating tube 223 may have a vacuum interlayer in the tube wall, or the insulating tube 223 may be made of an insulating material, which refers to a material having a thermal conductivity of less than 40W / (m·K) at 23°C and a relative humidity of 50%, preferably less than 10W / (m·K) or less than 1W / (m·K). For example, the insulating material may be made of at least one of a PAEK material, a PI material, or a PBI material, wherein the PAEK material includes PEEK, PEKK, PEKEKK, or PEK material. For example, the insulating material may include aerogel, glass fiber, glass felt, or felt.

[0102] The sealing assembly 5 may further include an upper end cap 52, which is connected to the proximal end of the insulation tube 223 and fixed on the insulation tube 223, so that the sealing assembly 5 can be combined with at least a part of the heating assembly 22 as a whole, and then the whole is assembled with the housing 21 or the whole is separated from the housing 21. The hardness of the upper end cap 52 is greater than the hardness of the flexible member 51, and the flexible member 51 is retained on the upper end cap 52. The upper end cap 52 can provide support for the flexible member 51, so that the flexible member 51 can be sealedly connected to the airway tube 32, and the flexible member 51 can be sealedly connected to the heating tube 222.

[0103] A gas insulation layer 224 can also be arranged between the insulation tube 223 and the heating tube 222. Part of the flexible member 51 can extend to be clamped between the upper end cover 52 and the insulation tube 223, thereby closing the proximal end of the gas insulation layer 224. The flexible member 51 provides a sealed connection between the upper end cover 52 and the heating tube 222 to prevent the aerosol in the second receiving cavity 221 from entering the gas insulation layer 224.

[0104] The upper end cover 52 may define at least a portion of the boundary of the distal end of the first receiving cavity 211 .

[0105] The heating assembly 22 may further include a lower end cap 225, which may be connected to the distal end of the insulation tube 223 and fixed on the insulation tube 223, and the lower end cap 225 may support the heating tube 222, so that the heating tube 222 may be retained in the insulation tube 223. The heating assembly 22 may further include a sealing gasket 226, at least a portion of which may be disposed between the lower end cap 225 and the heating tube 222, and provide a sealing connection between the heating tube 222 and the lower end cap 225, so as to prevent the aerosol in the second receiving cavity 221 from entering the gas insulation layer 224 between the insulation tube 223 and the heating tube 222. A portion of the sealing gasket 226 may extend to be clamped between the lower end cap 225 and the insulation tube 223, so as to seal the distal end of the gas insulation layer 224.

[0106] Therefore, the gas insulation layer 224 can form a sealed gas insulation layer or a negative pressure insulation layer under the action of the sealing assembly 5, the lower end cover 225 and the sealing gasket 226.

[0107] Of course, there may be a solid insulation layer between the insulation tube 223 and the heating tube 222, or there may be both a gas insulation layer 224 and a solid insulation layer.

[0108] Example 3: You can refer to Figure 1 When the push portion 33 is in the first position, the push portion 33 is located in the sealing assembly 5, that is, the first position is in the sealing assembly 5. At this time, the distal end of the airway tube 32 can also be located in the sealing assembly 5. Figure 2 When the pushing portion 33 is in the second position, the pushing portion 33 is located outside the sealing assembly 5. At this time, the distal end of the airway tube 32 can pass through the sealing assembly 5 and be located outside the sealing assembly 5, so that the proximal end and the distal end of the airway tube 32 are respectively located on opposite sides of the sealing assembly 5.

[0109] Example 4: Different from Example 2 and Example 3, the sealing component 5 is arranged in linkage with the pushing portion 33, and the sealing component 5 is configured to be removed from the second component 3 following the first component 2. When the pushing portion 33 moves from the first position to the second position along the first direction, the sealing component 5 can move synchronously with the pushing portion 33, and the sealing component 5 also moves relative to the housing 21 along the first direction, so that the spatial range of the first receiving cavity 211 changes. Alternatively, when the pushing portion 33 moves from the first position to the second position along the first direction, the sealing component 5 can also move relative to the housing 21 along the first direction, but the moving speed is different, so that the airway tube 32 can still be slidably connected with the sealing component 5.

[0110] It should be noted that the aerosol generating device provided in the third aspect has the features and attributes of any one or more embodiments provided in the first aspect and / or the second aspect, which is optional and not mandatory, and the third aspect can be independent of the first aspect and / or the second aspect.

[0111] In one embodiment based on the third aspect, the first receiving chamber 211 is in communication with an external fluid; or the suction nozzle 31 is in clearance fit with the first component 2, so that the first receiving chamber 211 is in communication with an external fluid. This prevents the first receiving chamber 211 from forming a closed space, so that when the user needs to press the suction nozzle 31 into the first receiving chamber 211, the air pressure in the first receiving chamber 211 is prevented from increasing, which may cause resistance to the suction nozzle 31 entering the first receiving chamber 211.

[0112] In the fourth aspect of the present application, in the provided aerosol generating device, the first component 2 also includes a cover component 25 and a material hole 261 for loading the aerosol generating matrix 1 into the second receiving cavity 221, and the cover component 25 is removably matched with the material hole 261. When the cover component 25 is matched with the material hole 261, the cover component 25 blocks the material hole 261 to prevent the aerosol generating matrix 1 from escaping from the aerosol generating device. After the cover component 25 is removed, the material hole 261 is exposed.

[0113] Based on the fourth aspect, in one embodiment, reference may be made to Figure 8-Figure 10 , at least part of the second receiving cavity 221 is formed in the cover assembly 25, and the first component 2 mainly receives and holds the aerosol generating substrate 1 through the cover assembly 25. The aerosol generating substrate 1 can be held in the housing 21 by making the cover assembly 25 cooperate with the material hole 261, and the aerosol generating substrate 1 is placed in a range that can be covered by the energy provided by the heating component 22, so that the aerosol generating substrate 1 can be heated and generate aerosol. When the cover assembly 25 is removed, at least part of the second receiving cavity 221 is separated from the interior of the housing 21 and exposed, that is, at least the second receiving cavity 221 located in the cover assembly 25 is separated from the interior of the housing 21 and exposed, which is convenient for the user to replace the aerosol generating substrate 1 held on the cover assembly 25 and to clean the second receiving cavity 221. In this embodiment, it is optional but not mandatory to use the above-mentioned pushing portion 33 to move from the first position to the second position along the first direction to squeeze or push the aerosol generating substrate 1 so that at least part of the aerosol generating substrate 1 is separated from the first component 2 or the housing 21. When the aerosol generating device in this embodiment also has the above-mentioned pushing portion 33, after the lock between the cover assembly 25 and the outer shell 21 or the cover plate 26 is released, the pushing portion 33 can push the cover assembly 25 along the first direction, so that the cover assembly 25 and the aerosol generating matrix 1 retained in the cover assembly 25 move together relative to the material hole 261 along the first direction to help the cover assembly 25 be removed from the material hole 261.

[0114] Based on the fact that at least a portion of the second receiving cavity 221 is formed in the cover assembly 25, when the cover assembly 25 cooperates with the material hole 261, at least a portion of the cover assembly 25 is accommodated in the material hole 261. After the cover assembly 25 is removed from the material hole 261, the cover assembly 25 is detached from the material hole 261 and is independent of the material hole 261.

[0115] Based on the fact that at least part of the second receiving cavity 221 is formed in the cover assembly 25, as an example, reference can be made to Figure 8-Figure 10 , the cover assembly 25 includes a base 251 and a receiving cup 252 disposed on the base 251. When the cover assembly 25 is matched with the material hole 261, at least a portion of the base 251 is exposed for user operation, for example, the user can operate the base 251 to remove the cover assembly 25 from the material hole 261, or operate the base 251 to accommodate at least a portion of the cover assembly 25 in the material hole 261. At least a portion of the second receiving cavity 221 is located in the receiving cup 252, and the side wall of the receiving cup 252 defines at least a portion of the boundary of the side of the second receiving cavity 252. A bottom support for supporting the aerosol generating substrate 1 may be provided on the receiving cup 252, or at least a portion of the base 251 may extend into the receiving cup 252 to support the aerosol generating substrate 1.

[0116] The heating assembly 22 may be configured to heat the aerosol generating substrate 1 from the circumferential direction. For example, the heating assembly 22 includes a heating tube 222, which can generate heat itself or a heating element is provided on the heating tube 222. When the cover assembly 25 is engaged with the material hole 261, at least a portion of the second Garner cavity 221 is located in the heating tube 222 and surrounded by the heating tube 222, so that when the heating tube 222 or the heating element on the heating tube 222 releases heat, the aerosol generating substrate 1 in the second Garner cavity 221 can be heated; or for example, the receiving cup 252 includes a susceptor that can generate heat in a changing magnetic field, and the heating assembly 22 includes a magnetic field generator for generating a changing magnetic field. When the cover assembly 25 is matched with the material hole 261, at least a portion of the receiving cup 252 is located in the coverage range of the magnetic field generated by the magnetic field generator, so that in the changing magnetic field generated by the magnetic field generator, at least a portion of the receiving cup 252 can respond to the magnetic field and generate eddy current and heat.

[0117] It should be noted that when the heating tube 222 itself can generate heat, the heating tube 222 may include a sensor, and at least a portion of the heating tube 222 is within the coverage of the changing magnetic field generated by the magnetic field generator in the heating component 22; or, when the heating tube 222 itself can generate heat, the heating tube 222 may be conductive ceramic, which has a large resistivity, so that Joule heat can be generated when the conductive ceramic is energized.

[0118] It should be noted that when a heating element is provided on the heating tube 222, the heating element may include a sensor; or the heating element may include a resistive heating element that generates Joule heat when powered on; or the heating element may include an infrared radiation layer, which can radiate infrared rays to the receiving cup 252 or to the second receiving cavity 221 when powered on or excited. Based on the infrared radiation layer provided on the heating tube 222, in one example, the side wall of the receiving cup 252 is configured to allow infrared rays to pass through, for example. The side wall of the receiving cup 252 is transparent, or the side wall of the receiving cup 252 is made of quartz or glass, so that infrared rays can be transmitted through the side wall of the receiving cup 252 and enter the second receiving cavity 221; or for example, reference can be made to Fig.10 The side wall of the receiving cup 252 has a notch 2521 or a through hole, or the side wall of the receiving cup 252 is incomplete, so that infrared rays can pass through the notch 2521 or the through hole on the side wall or through the missing part of the side wall and then be emitted into the second receiving cavity 221.

[0119] When the heating tube 222 itself can generate heat, or when the heating element disposed on the heating tube 222 includes a sensor or a resistive heating element, the heat released by the heating tube 222 and / or the heating element needs to be transferred to the aerosol generating matrix 1 in the second receiving chamber 221 through the receiving cup 252. In order to reduce power consumption, the side wall of the receiving cup 252 can be made of a thermally conductive material, which can be understood as a material having a thermal conductivity of at least 10 W / (m·k) at 23°C and a relative humidity of 50%, preferably at least 40 W / (m·k), more preferably at least 100 W / (m·k), or more preferably at least 150 W / (m·k), and most preferably at least 200 W / (m·k). Suitable thermally conductive materials include, but are not limited to, graphite, graphene, aluminum, copper, zinc, steel, silver, thermally conductive polymers, or any combination or alloy thereof.

[0120] The heating component 22 may be configured to heat the aerosol generating substrate 1 from the inside. For example, the heating component 22 includes a heating needle or a heating plate, which is inverted so that its free end faces the material hole 261, so that when the cover component 25 is matched with the material hole 261, it can be inserted into the second receiving cavity 221 and can be inserted into the aerosol generating substrate 1, so that the aerosol generating substrate 1 can be heated inside the aerosol generating substrate; or for example, the cover component 25 includes a heating needle or a heating plate, and at least a part of the heating needle or the heating plate is arranged in the second receiving cavity 221, so that when the aerosol generating substrate 1 is received in the second receiving cavity, the heating needle or the heating plate can be inserted into the second receiving cavity 221. At least a portion of the heating needle or heating plate is located inside the aerosol generating matrix 1, wherein the heating needle or heating plate includes a sensor capable of generating heat in a changing magnetic field, and the heating component 22 includes a magnetic field generator for generating a changing magnetic field. When the cover component 25 cooperates with the material hole 261, at least a portion of the heating needle or heating plate is located within the coverage range of the magnetic field generated by the magnetic field generator, so that in the changing magnetic field generated by the magnetic field generator, at least a portion of the heating needle or heating plate can respond to the magnetic field and generate eddy currents and heat, and heat the aerosol generating matrix from the inside.

[0121] Based on the fourth aspect, in one embodiment, reference may be made to Figure 2 and Figure 3 The second receiving chamber 221 is defined by the heating assembly 22. The second receiving chamber 221 and the cover assembly 25 are independent of each other. When the cover assembly 25 is matched with the material hole 261 and when the cover assembly 25 is removed to expose the material hole 261, the second receiving chamber 221 can be in the housing 21 and the position can remain unchanged. The cover assembly 25 includes a base 251. When the cover assembly 25 is matched with the material hole 261, at least a portion of the base 251 is exposed for user operation, and at least a portion of the base 251 can extend into the second receiving chamber 221 to support the aerosol generating substrate 1 in the second receiving chamber 221. In this embodiment, after the cover assembly 25 is removed to expose the material hole 261, the aerosol generating substrate 1 in the second receiving chamber 221 can be squeezed and pushed by moving the pushing portion 33 in the second assembly 3 along the first direction to the second position, so that at least a portion of the aerosol generating substrate 1 is pushed out of the second receiving chamber 221, or at least a portion of the aerosol generating substrate 1 is directly pushed out of the material hole 261. The user removes the aerosol generating substrate 1 in the first assembly 2 by moving the pushing portion 33 in the second assembly 3 along the first direction to the second position. In this embodiment, when the cover assembly 25 cooperates with the material hole 261, it is optional and not mandatory that at least a portion of the cover assembly 25 is accommodated in the material hole 261. When the material hole 261 is exposed by removing the cover assembly 25, the cover assembly 25 can remain connected to other parts of the first assembly 2, such as the cover plate 26.

[0122] In an embodiment where the second receiving cavity 221 is defined by the heating component 22, the heating component 22 is configured to heat the aerosol generating substrate 1 from the circumferential direction. For example, the heating component 22 includes a heating tube 222, the heating tube 222 itself can generate heat or a heating element is provided on the heating tube 222, and when the aerosol generating substrate 1 is received in the second receiving cavity 221, the heating tube 222 surrounds at least part of the aerosol generating substrate 1, and the heating component 22 can release heat to heat the aerosol generating substrate 1. The heating component 22 can heat the aerosol generating substrate 1 by energizing a resistor to generate Joule heat, or by using a susceptor to generate magnetic induction heat, or by radiating infrared rays.

[0123] In an embodiment in which the second receiving chamber 221 is defined by the heating component 22, the heating component 22 is configured to be able to heat the aerosol generating substrate 1 from the inside; alternatively, the heating component 22 may include an air heating element disposed upstream of the second receiving chamber 221 for heating the air flowing therethrough, and the hot air then enters the second receiving chamber 221 as the user inhales to heat the aerosol generating substrate 1 located in the second receiving chamber 221.

[0124] Based on the fourth aspect, in one embodiment, the aerosol generating device provided in the fourth aspect may have the features and properties of any one or more embodiments provided in at least one of the first to third aspects. It should be noted that the features and properties of any one or more embodiments provided in at least one of the first to third aspects by the aerosol generating device provided in the fourth aspect are optional and not mandatory, and the fourth aspect may be independent of at least one of the first to third aspects.

[0125] For example: In an embodiment in which at least a portion of the second receiving cavity 221 is formed in the cover assembly 25 and the cover assembly 25 can be removed from the material hole 261, it is optional for the second component 3 to have a pushing portion 33, it is optional for the first component 2 to be detachably connected to the second component 3, and it is optional for a sealing component 5 to be provided between the first receiving cavity 211 and the second receiving cavity 221.

[0126] Based on any one of the first aspect to the fourth aspect, in one embodiment, reference may be made to Figure 1-Figure 3 When the first component 2 is engaged with the second component 3, the nozzle 31 is disposed adjacent to the first component 2 or the proximal end of the housing 21. The first component 2 further includes a cover plate 26 disposed at the distal end of the housing 21, and a material hole 261 is formed on the cover plate 26. The cover component 25 can be detachably connected to the cover plate 26. For example, the base 251 in the cover component 25 can be screwed and connected to the cover plate 26. Figure 3 In the embodiment shown, the cover plate 26 is provided with an inverted L-shaped groove 262. Figure 8-Figure 11In the illustrated embodiment, a protrusion 2513 is provided on the base 251 of the cover assembly 25. The protrusion 2513 moves along the inverted L-shaped groove 262 to complete the screw-on operation, so that the cover assembly 25 and the cover plate 26 remain connected. The protrusion 2513 moves in the reverse direction along the inverted L-shaped groove 262 to complete the unlocking operation, so that the cover assembly 25 can be separated from the cover plate 26. When the cover plate 26 is combined with the housing 21, a part of the cover plate 26 extends into the housing 21 and abuts against the lower end cover 225 of the heating assembly 22, so that the heating assembly 22 can be kept in the housing 21.

[0127] Based on any one of the first aspect to the fourth aspect, in one embodiment, reference may be made to Figure 8-Figure 12 An air inlet channel and a filter 253 are provided in the cover assembly 25. The air inlet channel is connected to the outside and the second receiving chamber 221. The filter 253 is provided between the air inlet channel and the second receiving chamber 221 to block the debris or particles falling from the aerosol generating matrix 1 and prevent the air inlet channel from being blocked.

[0128] The filter screen 253 may define the distal boundary of the second receiving cavity 221, so that when the aerosol-generating substrate 1 is received in the second receiving cavity 221, the filter screen 253 can support the aerosol-generating substrate 1. The filter screen 253 may be spaced apart from the second receiving cavity 221, so that when the aerosol-generating substrate 1 is received in the second receiving cavity 221, there is a space between the filter screen 253 and the aerosol-generating substrate 1 to prevent the aerosol-generating substrate 1 from blocking the filter screen 253.

[0129] In one example, the base 251 includes a second base 2512 and a first base 2511 that are connected to each other. An operating unit 2513 is provided on the second base 2512 for user operation. The filter 253 is retained on the first base 2511. An air inlet 2514 connecting the air inlet channel with the outside world can be provided on the second base 2512 of the cover assembly 25. Liquid accumulation spaces 2515 are provided in the first base 2511 and the second base 2512 for collecting the condensate condensed on the base 251 by the oil from the second receiving chamber 221 and the refluxed aerosol to prevent liquid leakage.
