[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202420594840.4, filed with the Patent Office of China on March 22, 2024, entitled “Aerosol Generating Device,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of aerosol generation, and in particular to an aerosol generating device. Background Art

[0004] An aerosol generating device is a device that can generate aerosol from a smoking product.

[0005] In related art, an aerosol-generating device includes a mouthpiece, a heating element, an airway tube, and a container for holding tobacco products. The heating element heats the tobacco products to generate aerosol, and the mouthpiece is fluidically connected to the container via the airway tube. However, only a portion of the smoke generated by the tobacco products flows along the airway tube into the mouthpiece; the remainder flows outside the airway tube and condenses, thereby adhering to components between the mouthpiece and the container. This not only affects the performance of some functions of the aerosol-generating device but also reduces the amount of smoke produced in a puff, affecting the puff's taste.

[0006] Application Contents

[0007] The purpose of this application is to provide an aerosol generating device that can reduce the adverse effects of aerosols and improve the puffing taste.

[0030] As an example, the sealing component is arranged in linkage with the pushing portion, and the sealing component is configured to be removable from the second component following the first component.

[0031] As an example, the pushing portion is provided with one or more air holes to fluidically connect the second receiving cavity and the airway tube;

[0065] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between.

[0066] 1 to 3 , an embodiment of the present application provides an aerosol generating device, which is a device capable of engaging with an aerosol generating substrate 1 and interacting with the aerosol generating substrate 1 to enable the aerosol generating substrate 1 to generate aerosol.

[0067] The aerosol-forming substrate 1 is a substance that can generate aerosols under the action of increased temperature or ultrasound or microwaves. The aerosol-forming substrate 1 can be a volatile compound that is intended to be heated rather than burned to release to form an aerosol. The aerosol-forming substrate 1 can be in a solid form, for example, it can be an aggregate formed by the aggregation of tobacco shreds, tobacco leaves or tobacco particles. The aerosol-forming substrate 1 can include a tobacco-containing material, the tobacco-containing material containing volatile tobacco flavor compounds released from the substrate when heated, or the tobacco-containing material is a substance containing nicotine. The aerosol-forming substrate 1 can include a non-tobacco-containing material. The aerosol-forming substrate 1 can contain both tobacco-containing material and non-tobacco material.

[0068] The aerosol-generating device comprises a first component 2 and a second component 3. The second component 3 comprises a mouthpiece 31, at least a portion of which can be held in the mouth of a user. By holding and inhaling the mouthpiece 31, the user inhales the aerosol generated by the aerosol-generating substrate 1 in the aerosol-generating device into the oral cavity. The first component 2 comprises a housing 21, which defines a second receiving cavity 221 for receiving at least a portion 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, which releases heat to heat the aerosol-generating substrate 1, thereby generating an aerosol.

[0069] To prevent the aerosol generated by the aerosol-generating substrate 1 from being too hot and burning the mouthpiece when the heat released by the heating component is applied, when the first component 2 and the second component 3 are coupled, the mouthpiece 31 and the second receiving chamber 221 are spaced apart, so that the airflow channel connecting the mouthpiece 31 and the second receiving chamber 221 has a relatively long length, allowing the aerosol to dissipate heat more effectively as it flows along the airflow channel. Based on this, in one embodiment, referring to Figures 1-3 , the housing 21 of the first component 2 further includes a first receiving chamber 211. When the first component 2 and the second component 3 are coupled, at least a portion of the first receiving chamber 211 is located between the mouthpiece 31 and the second receiving chamber 221. The second component 3 also includes an airway tube 32 having an airway therein that constitutes at least a portion of the airflow channel, thereby enabling the airway tube 32 to fluidically connect the mouthpiece 31 and the second receiving chamber 221. At least a portion of the airway tube 32 is received in the first receiving cavity 211 , so that at least a portion of the airway tube 32 is disposed between the suction nozzle 31 and the second receiving cavity 221 , such that the suction nozzle 31 is spaced apart from the second receiving cavity 221 .

[0070] The aerosol-forming substrate 1 is removably coupled to the first component 2, so that the aerosol-forming substrate 1 in the first component 2 can be replaced, allowing the first component 2 to be used repeatedly, thereby reducing the cost of using the aerosol generating device.

[0071] In the first aspect of the present application, in the provided aerosol generating device, the second component 3 further includes a pushing portion 33. After the first component 2 and the second component 3 are engaged, the pushing portion 33 can move relative to the housing 21 of the first component 2 from a first position to a second position along a first direction. The second position is located in the second receiving chamber 221; or the first position and the second position are located on opposite sides of the second receiving chamber 221. Thus, during the movement of the pushing portion 33 of the second component 3 along the first direction to the second position, the pushing portion 33 can squeeze the aerosol generating substrate 1 located in the second receiving chamber 221, compacting the relatively loose aerosol generating substrate 1 in the second receiving chamber 221, or can push at least a portion of the aerosol generating substrate 1 out of the second receiving chamber 221, thereby making it easier for the user to remove the aerosol generating substrate 1 from the first component 2.

[0072] Based on the first aspect, in one embodiment, referring to Figures 1 to 3 and 6 , the aerosol generating device further includes an elastic component 4. The elastic component 4 can support the second component 3 so that the push portion 33 can remain in the first position and prevent the push portion 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 portion 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 portion 33. When the push portion 33 is in the first position, the elastic component 4 supports or pulls the second component 3 to prevent the push portion 33 from moving to the second position. When the push portion 33 is in the second position, the elastic component 4 supports or pulls the second component 3 so that the push portion 33 can automatically move from the second position to the first position. 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.

[0073] As an example, referring to Figure 6 , the second component 3 includes a moving component and a positioning component A. The positioning component A can remain connected to the first component 2, or after the first component 2 and the second component 3 are engaged, the positioning component A can remain stationary relative to the first component 2 in a first direction. The moving component can move relative to the positioning component A, with the pushing portion 33 being a component of the moving component. Thus, after the second component 3 and the first component 2 are engaged, the pushing portion 33 can be moved relative to the positioning component A from a first position to a second position by driving the moving component in the second component 3.

[0074] In this example, the moving component includes a suction nozzle 31 and an airway tube 32, and the pushing part 33 is connected to the airway tube 32, and the suction nozzle 31, the airway tube 32 and the pushing part 33 are linked together; the elastic component 4 is arranged in the second component 3, or when the pushing part 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 suction 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 part 33 is in the first position, the elastic component 4 can support the moving component so that the pushing part 33 can remain in the first position.

[0075] In the embodiment shown in Figure 6, the first component 2 further includes a first magnetic member 23. The movable component further includes a second magnetic member A1, which is retained 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, allowing the first component 2 and the second component 3 to remain connected, preventing the user from removing the second component 3 from the first component 2 while holding the nozzle 31. The first component 2 further includes a support platform 24, which supports the positioning component A and prevents the positioning component A from moving along with the movable component in the first direction.

[0076] As an example, referring to Figures 1 to 3, when the first component 2 is engaged with the second component 3, the elastic component 4 is arranged between the first component 2 and the second component 3, so that the second component 3 can move as a whole 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, referring to Figures 1-3, the elastic assembly 4 includes an elastic member 42 and a movable seat 41 movable relative to the housing 21 of the first assembly 2. The movable seat 41 is connected to the second assembly 3, and the displacement of the movable seat 41 is linked to the displacement of the push portion 33. The elastic member 42 is connected to the movable seat 41, so that the deformation of the elastic member 42 is linked to the displacement of the movable seat 41. When the push portion 33 is in the first position and / or the second position, the elastic member 42 can continue to support or pull the movable seat 41, thereby allowing the elastic assembly 4 to continue to support or pull the second assembly 3.

[0079] The elastic component 4 can constitute a module independent of the first component 2 and / or the second component 3 to facilitate the engagement and separation of the elastic component 4 with the first component 2, or to facilitate the engagement and separation of the elastic component 4 with the second component 3. In this regard, referring to Figures 1-3, the elastic component 4 also includes a retaining seat 43. One end of the elastic member 42 is connected to the movable seat 41, and the other end is connected to the retaining seat 43.

[0080] Furthermore, the retaining seat 43 may include a first side wall 431 that is slidably connected to the movable seat 41. When the elastic member 42 is deformed, the movable seat 41 may slide along the first side wall 431. The first side wall 431 can prevent the elastic member 42 from twisting when deformed. The retaining seat 43 may also include a second side wall 432. When the pushing portion 33 is in the first position, as shown in Figures 1 and 3, the second side wall 432 is spaced apart from the movable seat 41; when the pushing portion 33 is in the second position, as shown in Figure 2, the second side wall 432 abuts against the movable seat 42 to prevent the movable seat 42 from continuing to move along the original moving direction.

[0081] As an example, the first sidewall 431 and the second sidewall 432 are radially spaced apart, and a portion of the elastic member 42 can be retained between the first sidewall 431 and the second sidewall 432. In the embodiment shown in Figures 1-3, 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.

[0082] As an example, referring to Figures 1 to 3, a guide rail 433 is provided on one of the retaining seat 43 and the movable seat 41, and a slider 411 is provided on the other. During the process of the pushing portion 33 moving 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 movable seat 41 from rotating.

[0083] Based on the first aspect, in one embodiment, as shown in Figures 1 and 2 , the suction nozzle 31 is arranged in conjunction 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, as shown in Figure 1 , at least a portion of the suction nozzle 31 is exposed outside the housing 21 for user operation. When the push portion 33 is in the second position, as shown in Figure 2 , at least a portion of the suction nozzle 31 is located within the first receiving cavity 211.

[0084] The user can drive the pusher 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 pusher 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 other than the suction nozzle 31.

[0085] 1 and 2 , the movable base 41 supports the suction nozzle 31, allowing the suction nozzle 31 to move with the movable base 41, thereby interlocking the suction nozzle 31 with the pushing portion 33. When the pushing portion 33 is in the first position, the movable base 41 supports the suction nozzle 31 and keeps at least a portion of the suction nozzle 31 outside the housing 21. When the pushing portion 33 is in the second position, the elastic member 42 deforms, creating space in the first receiving cavity 211, allowing at least a portion of the suction nozzle 31 to be received in the first receiving cavity 211.

[0086] In the second aspect of the present application, in the provided aerosol generating device, the first component 2 and the second component 3 are detachably connected, 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.

[0087] 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.

[0088] 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 to each other and can be combined, interact and interact with the characteristics and properties of any one or more embodiments provided by the first aspect.

[0089] For example, the second component 3 can 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.

[0090] 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. For example, referring to FIG3 , an L-shaped groove 412 is provided on the movable seat 41, and a latch 311 is provided on the suction nozzle 31. First, the latch 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 latch 311 is made to slide along the horizontal groove in the L-shaped groove 412. The latch 311 is thus engaged with the L-shaped groove 412. The interference between the latch 311 and the horizontal groove can prevent the suction nozzle 31 from detaching from the movable seat 41, thereby maintaining the connection between the first component 2 and the second component 3. The slider 411 between the movable seat 41 and the retaining seat 43 cooperates with the guide rail 433 to prevent the movable seat 41 from rotating when linked with the push portion 33, thereby preventing the first component 2 from separating from the second component 3 when the push portion 33 moves in the first direction and the second direction.

[0091] Alternatively, the detachable connection between the movable base 41 and the second component 3 includes a magnetic connection between the movable base 41 and the second component 3. Alternatively, the detachable connection between the movable base 41 and the suction nozzle 31 includes a threaded connection between the movable base 41 and the second component 3.

[0092] Based on the second aspect, in one embodiment, referring to Figures 1-5 , the airway tube 32 is connected to the push portion 33, and the push portion 33 is disposed at the distal end of the airway tube 32, thereby interlocking the airway tube 32 and the push portion 33. The push portion 33 may be provided with one or more air holes 331 to fluidically connect the second receiving cavity 221 and the airway tube 32. The air holes 331 provided on the push portion 33 can also prevent fragments, particles, or leaves of the aerosol-generating matrix 1 from entering the airway tube 32, thereby preventing the airway tube 32 from becoming clogged and preventing the user from inhaling solid matter, such as fragments, particles, or leaves of the aerosol-generating matrix 1, into the oral cavity.

[0093] During at least a portion of the movement of the pushing portion 33 from the first position to the second position, the pushing portion 33 may contact the aerosol-generating substrate 1. To prevent the aerosol-generating substrate 1 from adhering to the pushing portion 33 and clogging the air holes 331, or to prevent the aerosol from condensing on the pushing portion 33 to form a viscous or solid substance that blocks the air holes 331, the pushing portion 33 can be cleaned after the second component 3 is removed from the first component 2. In one embodiment, the pushing portion 33 is detachably connected to the airway tube 32, so that the pushing portion 33 can be removed and cleaned, or replaced. Of course, in other embodiments, the pushing portion 33 can be integrally formed with the airway tube 32.

[0094] The pushing portion 33 can be made of metal, ceramic or plastic.

[0095] In one embodiment, referring to Figures 1 to 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 condensation in the suction nozzle 31 or the airway tube 32 to prevent the user from inhaling the condensation into the mouth.

[0096] It should be noted that it is optional and not mandatory for the aerosol generating device provided in the second aspect to have the features and properties of any one or more embodiments provided in the first aspect, and at least some of the features or structures of the second aspect may be independent of the first aspect.

[0097] In a third aspect of the present application, the provided aerosol generating device further includes a sealing assembly 5. The sealing assembly 5 is connected to the airway tube 32 in the second assembly 3, with the first receiving cavity 211 and the second receiving cavity 221 being isolated from each other on opposite sides of the sealing assembly 5. Thus, the sealing assembly 5 can facilitate the aerosol formed in the second receiving cavity 221 to pass through the airway tube 32 and enter the mouthpiece 31, while preventing the aerosol from entering the first receiving cavity 211. This keeps the first receiving cavity 211 clean and prevents any impact on the performance and functionality of components disposed within the first receiving cavity 211 (e.g., preventing viscous matter formed by condensed aerosol from adhering to the elastic component 4 and / or the outer wall of 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 housing 21). The sealing assembly 5 also helps concentrate the formed aerosol on the mouthpiece 41, thereby improving the fullness and taste of each puff.

[0098] 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 5 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.

[0099] Example 1: Referring to Figures 1 to 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 movable 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 movable seat 41, an elastic member 42 and a retaining seat 43, and the opposite ends of the elastic member 42 are respectively connected to the movable seat 41 and the retaining seat 43, and the movable seat 41 is connected to the second component 3 and is linked to the push portion 33. 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.

[0100] Example 2: Referring to Figures 1 to 3 and 7, the sealing assembly 5 is fixed in the housing 21. When the first assembly 2 can be detachably connected to the second assembly 3, the second assembly 3 is detachably connected to the sealing assembly 5, so that when the second assembly 3 is removed from the first assembly 2, the second assembly 3 is also separated from the sealing assembly 5, and the sealing assembly 5 can continue to remain in the housing 21.

[0101] Furthermore, during the movement of the pushing portion 33 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.

[0102] In the embodiment shown in Figures 1-3 and 7 , the heating assembly 22 includes a heating tube 222. The second receiving cavity 221 is at least partially disposed within the heating tube 222. The sealing assembly 5 includes a flexible member 51 that seals the airway tube 32 and the heating tube 222. The flexible member 51 can be made of silicone, rubber, or sponge. The flexible member 51 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 part 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 part 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.

[0103] To reduce power consumption, the heating assembly 22 may further include an insulating tube 223 disposed around the heating tube 222. The insulating tube 223 is configured to prevent heat from being lost radially outward, thereby concentrating and retaining the heat within the second receiving chamber 221. The insulating tube 223 may have a vacuum interlayer within its wall, or the insulating tube 223 may be made of an insulating material. An insulating material refers to a material having a thermal conductivity of less than 40 W / (m·K) at 23°C and a relative humidity of 50%. For example, an insulating material refers to a material having a thermal conductivity of less than 10 W / (m·K) or less than 1 W / (m·K) at 23°C and a relative humidity of 50%. For example, the insulating material may be made of at least one of a PAEK-based material, a PI material, or a PBI material, wherein the PAEK-based material includes PEEK, PEKK, PEKEKK, or PEK material. For example, the insulating material may include aerogel, glass fiber, glass mat, or felt.

[0104] 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 to the insulation tube 223, so that the sealing assembly 5 can be combined with at least a portion of the heating assembly 22 to form a whole, which can then be assembled with the housing 21 or 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, allowing the flexible member 51 to be sealedly connected to the airway tube 32 and the heating tube 222.

[0105] A gas insulation layer 224 can also be provided 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 aerosol in the second receiving cavity 221 from entering the gas insulation layer 224.

[0106] The upper end cap 52 may define at least a portion of the boundary of the distal end of the first receiving cavity 211 .

[0107] The heating assembly 22 may further include a lower end cap 225, which may be connected to the distal end of the insulating tube 223 and fixed thereto. The lower end cap 225 may support the heating tube 222, thereby retaining the heating tube 222 within the insulating 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, thereby providing a sealed connection between the heating tube 222 and the lower end cap 225 and preventing aerosol in the second receiving chamber 221 from entering the gas insulation layer 224 between the insulating 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 insulating tube 223, thereby sealing the distal end of the gas insulation layer 224.

[0108] 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 component 5, the lower end cover 225 and the sealing gasket 226.

[0109] 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.

[0110] Example 3: Referring to Figure 1 , when the pushing portion 33 is in the first position, the pushing 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 may also be located in the sealing assembly 5. Referring to 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.

[0111] Example 4: Unlike Examples 2 and 3, the sealing assembly 5 is interlocked with the push portion 33 and is configured to be removed from the second assembly 3 along with the first assembly 2. When the push portion 33 moves along the first direction from the first position to the second position, the sealing assembly 5 can move synchronously with the push portion 33 and also move relative to the housing 21 along the first direction, thereby changing the spatial extent of the first receiving cavity 211. Alternatively, when the push portion 33 moves along the first direction from the first position to the second position, the sealing assembly 5 can also move relative to the housing 21 along the first direction, but at a different speed, so that the airway tube 32 can still be slidably connected to the sealing assembly 5.

[0112] 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.

[0113] In one embodiment based on the third aspect, the first receiving chamber 211 is in fluid communication with the outside world; or, the suction nozzle 31 is loosely fitted with the first component 2, allowing the first receiving chamber 211 to be in fluid communication with the outside world. This prevents the first receiving chamber 211 from forming a sealed space, and when a user presses the suction nozzle 31 into the first receiving chamber 211, the air pressure in the first receiving chamber 211 is prevented from increasing, thereby preventing the suction nozzle 31 from entering the first receiving chamber 211.

[0114] In the fourth aspect of the present application, in the provided aerosol generating device, the first component 2 also includes a cover assembly 25 and a material hole 261 for loading the aerosol generating matrix 1 into the second receiving cavity 221. The cover assembly 25 is removably engaged with the material hole 261. When the cover assembly 25 is engaged with the material hole 261, the cover assembly 25 blocks the material hole 261 to prevent the aerosol generating matrix 1 from escaping from the aerosol generating device. After the cover assembly 25 is removed, the material hole 261 is exposed.

[0115] With reference to the fourth aspect, in one embodiment, referring to Figures 8-10 , at least a portion of the second receiving cavity 221 is formed in the cover assembly 25, and the first assembly 2 primarily receives and retains the aerosol-generating substrate 1 via the cover assembly 25. The cover assembly 25 can be mated with the material hole 261 to retain the aerosol-generating substrate 1 within the housing 21 and ensure that the aerosol-generating substrate 1 is within a range that can be covered by the energy provided by the heating assembly 22, thereby enabling the aerosol-generating substrate 1 to be heated and generate an aerosol.

[0116] When the cover assembly 25 is removed, at least a portion of the second receiving chamber 221 is separated from the interior of the outer shell 21 and exposed, that is, at least the second receiving chamber 221 located in the cover assembly 25 is separated from the interior of the outer shell 21 and exposed, which makes it convenient for the user to replace the aerosol generating matrix 1 retained on the cover assembly 25 and to clean the second receiving chamber 221.

[0117] In this embodiment, the pushing portion 33 is moved 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. This is optional but not mandatory.

[0118] 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 housing 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 substrate 1 retained in the cover assembly 25 move together relative to the material hole 261 along the first direction to help remove the cover assembly 25 from the material hole 261.

[0119] 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 becomes independent of the material hole 261.

[0120] At least a portion of the second receiving cavity 221 is formed in the lid assembly 25. As an example, referring to Figures 8-10 , the lid assembly 25 includes a base 251 and a receiving cup 252 disposed on the base 251. When the lid assembly 25 is engaged 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 lid assembly 25 from the material hole 261, or operate the base 251 to accommodate at least a portion of the lid assembly 25 within the material hole 261. At least a portion of the second receiving cavity 221 is located in the receiving cup 252, and the sidewalls of the receiving cup 252 define at least a portion of the side edges of the second receiving cavity 252. The receiving cup 252 may be provided with a base for supporting the aerosol-generating substrate 1, or at least a portion of the base 251 may extend into the receiving cup 252 to support the aerosol-generating substrate 1.

[0121] The heating assembly 22 can be configured to circumferentially heat the aerosol-generating substrate 1. For example, the heating assembly 22 includes a heating tube 222, which can generate heat itself or has a heating element disposed thereon. When the lid assembly 25 is engaged with the material hole 261, at least a portion of the second Gardner cavity 221 is located within and surrounded by the heating tube 222. As a result, when the heating tube 222 or the heating element on the heating tube 222 releases heat, the aerosol-generating substrate 1 in the second Gardner cavity 221 can be heated. Alternatively, for example, the receiving cup 252 includes a susceptor capable of generating heat in a varying magnetic field. The heating assembly 22 includes a magnetic field generator for generating a varying magnetic field. When the lid assembly 25 is engaged with the material hole 261, at least a portion of the receiving cup 252 is located within the coverage of the magnetic field generated by the magnetic field generator. As a result, in the varying 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 currents and generate heat.

[0122] 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 range of the changing magnetic field generated by the magnetic field generator in the heating assembly 22; or, when the heating tube 222 itself can generate heat, the heating tube 222 may be a conductive ceramic, which has a large resistivity, so that Joule heat can be generated when the conductive ceramic is energized.

[0123] 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 toward the receiving cup 252 or the second receiving cavity 221 when powered on or excited.

[0124] Based on the infrared radiation layer provided on the heating tube 222, in one example, the sidewall of the receiving cup 252 is configured to allow infrared rays to pass through. For example, the sidewall of the receiving cup 252 is transparent, or made of quartz or glass, so that infrared rays can pass through the sidewall of the receiving cup 252 and enter the second receiving cavity 221. Alternatively, as shown in FIG. 10 , the sidewall of the receiving cup 252 has a notch 2521 or a through-hole, or the sidewall of the receiving cup 252 is incomplete, so that infrared rays can pass through the notch 2521 or through-hole, or through the missing portion of the sidewall, and enter the second receiving cavity 221.

[0125] When the heating tube 222 itself is capable of generating heat, or when the heating element disposed on the heating tube 222 comprises a susceptor 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 substrate 1 in the second receiving chamber 221 via the receiving cup 252. To reduce power consumption, the sidewalls of the receiving cup 252 may be made of a thermally conductive material. The thermally conductive material may be understood as a material having a thermal conductivity of at least 10 W / (m·K), for example, at least 40 W / (m·K), or further, at least 100 W / (m·K), or at least 150 W / (m·K), or further, at least 200 W / (m·K) at 23°C and 50% relative humidity. 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.

[0126] 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 portion of the heating needle or heating plate is disposed 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 heating plate 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 is matched 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, thereby heating the aerosol generating matrix from the inside.

[0127] Based on the fourth aspect, in one embodiment, referring to Figures 2 and 3, the second receiving chamber 221 is defined by the heating assembly 22, and 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 outer shell 21 and the position can remain unchanged.

[0128] The lid assembly 25 includes a base 251. When the lid assembly 25 is engaged 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 cavity 221 to support the aerosol-generating substrate 1 in the second receiving cavity 221. In this embodiment, after the lid assembly 25 is removed to expose the material hole 261, the pushing portion 33 of the second component 3 can be moved in the first direction to the second position to squeeze and push the aerosol-generating substrate 1 in the second receiving cavity 221, thereby pushing at least a portion of the aerosol-generating substrate 1 out of the second receiving cavity 221, or directly pushing at least a portion of the aerosol-generating substrate 1 out of the material hole 261. The user can then remove the aerosol-generating substrate 1 from the first component 2 by moving the pushing portion 33 of the second component 3 in the first direction to the second position.

[0129] In this embodiment, when the cover assembly 25 cooperates with the material hole 261, it is optional but not necessary for the cover assembly 25 to be at least partially accommodated in the material hole 261. When the material hole 261 is exposed by removing the cover assembly 25, the cover assembly 25 can still remain connected to other parts of the first component 2, such as the cover plate 26.

[0130] In one embodiment, in which the second receiving cavity 221 is defined by a heating assembly 22, the heating assembly 22 is configured to circumferentially heat the aerosol-generating substrate 1. For example, the heating assembly 22 includes a heating tube 222, which can generate heat itself or be provided with a heating element. When the aerosol-generating substrate 1 is received in the second receiving cavity 221, the heating tube 222 surrounds at least a portion of the aerosol-generating substrate 1, and the heating assembly 22 releases heat to heat the aerosol-generating substrate 1. The heating assembly 22 can heat the aerosol-generating substrate 1 by generating Joule heating through electrical resistance, generating magnetic induction heating through a susceptor, or radiating infrared light.

[0131] 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.

[0132] 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 aerosol generating device provided in the fourth aspect having the features and properties of any one or more embodiments provided in at least one of the first to third aspects is optional and not mandatory, and the fourth aspect may be independent of at least one of the first to third aspects.

[0133] 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 and not mandatory for the second component 3 to have a pushing portion 33, it is optional and not mandatory for the first component 2 and the second component 3 to be detachably connected, and it is optional and not mandatory for a sealing assembly 5 to be provided between the first receiving cavity 211 and the second receiving cavity 221.

[0134] Based on any aspect of the first to fourth aspects, in one embodiment, referring to Figures 1-3, when the first component 2 is engaged with the second component 3, the suction nozzle 31 is arranged adjacent to the proximal end of the first component 2 or the shell 21, and the first component 2 also includes a cover plate 26 arranged at the distal end of the shell 21, and the material hole 261 is formed on the cover plate 26.

[0135] The cover assembly 25 can be detachably connected to the cover plate 26. For example, the base 251 of the cover assembly 25 can be screwed onto the cover plate 26. In the embodiment shown in FIG3 , an inverted L-shaped groove 262 is provided on the cover plate 26. In the embodiment shown in FIG8-11 , 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 a screwing operation, thereby maintaining the connection between the cover assembly 25 and the cover plate 26. The protrusion 2513 moves in the opposite direction along the inverted L-shaped groove 262 to complete an unlocking operation, thereby allowing the cover assembly 25 to be separated from the cover plate 26. When the cover plate 26 is assembled with the housing 21, a portion of the cover plate 26 extends into the housing 21 and abuts against the lower end cover 225 of the heating assembly 22, thereby maintaining the heating assembly 22 within the housing 21.

[0136] Based on any aspect of the first to fourth aspects, in one embodiment, referring to Figures 8-12, 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, and the filter 253 is provided between the air inlet channel and the second receiving chamber 221 to block fragments or particles falling from the aerosol generating matrix 1 and prevent the air inlet channel from being blocked.

[0137] 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 clogging the filter screen 253.

[0138] In one example, the base 251 includes a second base 2512 and a first base 2511 connected to each other. The second base 2512 is provided with an operating portion 2513 for user operation. The filter 253 is retained on the first base 2511. The 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. Both the first base 2511 and the second base 2512 are provided with a liquid accumulation space 2515 for collecting oil from the second receiving chamber 221 and condensed liquid on the base 251 from the returning aerosol, thereby preventing liquid leakage. As shown in Figure 12, the liquid accumulation space 2515 on the second base 2512 is arranged corresponding to the air vent 2516 on the first base 2511, and the air vent 2516 and the air inlet 2514 are staggered with each other, so that after the outside air enters the second base 2512 through the air inlet 2514, it needs to turn rearward to enter the first base 2511 through the air vent 2516, and then enter the second receiving chamber 221, thereby preventing the air inlet 2514 from being blocked.

[0139] In one example, the filter 253 and the receiving cup 252 are integrally formed.

[0140] Based on any of the first to fourth aspects, in one embodiment, with reference to Figures 1-3, the first component 2 further includes a power supply component 27, which is electrically connected to the heating component 22. The power supply component 27 is used to provide power for the heating component 22 to release energy, such as heat energy or generate an electromagnetic field.
