[0053] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present.

[0054] Please refer to Figures 1-7 An embodiment of the present application provides an aerosol generating device 100, which includes a storage assembly 1 and a main assembly 2. The storage assembly 1 is independent of the main assembly 2, and the two assemblies can be connected to each other by being assembled from a phase separation state.

[0055] The storage assembly 1 includes a first housing 11 having a first storage cavity inside and a base 12 sealing the first storage cavity. The main assembly 2 includes an atomization core 22 capable of atomizing an aerosol generating substrate to generate an aerosol. When the storage assembly 1 is connected to the main assembly 2, the storage assembly 1 can be held in one of a first position and a second position of the main assembly 2.

[0056] It should be noted that the storage assembly 1 being capable of being held in the first position of the main assembly 2 means that, in a general state, when the storage assembly 1 is in the first position, the storage assembly 1 and the main assembly 2 can be relatively stably connected to each other or have a relatively stable positional relationship, or even the storage assembly 1 and the main assembly 2 can be relatively stationary. The storage assembly 1 being capable of being held in the second position of the main assembly 2 means that, in a general state, when the storage assembly 1 is in the second position, the storage assembly 1 and the main assembly 2 can be relatively stably connected to each other or have a relatively stable positional relationship, or even the storage assembly 1 and the main assembly 2 can be relatively stationary.

[0057] In the storage assembly 1 is in the second position, a channel between the atomization core 22 and the first storage cavity is formed, and the aerosol generating substrate in the storage assembly 1 can be guided into the main assembly 2 through the channel, so that the atomization core 22 can atomize the aerosol generating substrate from the storage assembly 1 to generate an aerosol.

[0058] Thus, when the storage assembly 1 is in the second position, the storage assembly 1 and the main assembly 2 can be relatively stably connected to each other, and the first storage cavity and the atomization core 22 can be in fluid communication.

[0059] It can be understood that, when the storage assembly 1 is in the first position, the storage assembly 1 and the main assembly 2 can be relatively stably connected to each other, but the channel between the first storage cavity and the atomization core 22 is not formed. Therefore, when the storage assembly 1 is in the first position, the first storage cavity in the storage assembly 1 is still in a sealed state, and the aerosol generating substrate in the first storage cavity cannot be guided out.

[0060] In some embodiments, reference can be made to Figure 1 , Figure 3 and Figure 6 The base 12 is provided with a first hole 1213 for providing the output of the aerosol generating substrate and a sealing portion for sealing the first hole 1213. When the sealing portion is intact or when the sealing portion is kept in a position to seal the first hole 1213, the first storage cavity is in a sealed state. When the sealing portion is damaged or after the sealing portion is removed, the first hole 1213 is opened, and a channel between the atomization core 22 and the first storage cavity is formed.

[0061] Further, the main assembly 2 further comprises a flow guide 23. When the storage assembly 1 is located at the second position, the flow guide 23 breaks the seal portion, and the aerosol generating substrate in the first storage cavity can thus flow out through the first hole 1213, so that a channel for fluid communication between the atomization core 22 and the first storage cavity is formed. Here, the flow guide 23 breaking the seal portion includes the flow guide 23 piercing the seal portion to break the integrity of the seal portion, or includes the flow guide 23 pushing the seal portion to move in position, thereby breaking the seal of the seal portion on the first hole 1213.

[0062] Correspondingly, when the storage assembly 1 is located at the first position, the flow guide 23 can keep a gap with the seal portion, or can have an interference force with the seal portion, so that the seal portion can remain intact or remain in a position that seals the first hole 1213. Therefore, when the storage assembly 1 is located at the first position, the channel for fluid communication between the first storage cavity and the atomization core 22 cannot be formed.

[0063] In some embodiments, the storage assembly 1 is configured to be snap-connected with the main assembly 2 when located at the first position, so that the storage assembly 1 can be kept at the first position.

[0064] Further, it can be referred to Figure 1 and Figure 3 that the main assembly 2 further comprises a second housing 21, and the atomization core 22 is arranged in the second housing 21. When the storage assembly 1 is located at the first position, the second housing 21 is snap-connected with the first housing 11, so that the storage assembly 1 can be kept at the first position.

[0065] In some embodiments, the second housing 21 has a receiving cavity for at least partially accommodating the storage assembly 1. When the storage assembly 1 is located at the first position, at least part of the storage assembly 1 can be located in the receiving cavity.

[0066] More specifically, it can be referred to Figure 4 that when the storage assembly 1 is located at the first position, at least part of the first housing 11 can be located in the receiving cavity, so that the first housing 11 can be snap-connected with the second housing 21 inside the second housing 21. When the first housing 11 is snap-connected with the second housing 21 when the storage assembly 1 is located at the first position, the parts of the first housing 11 and the second housing 21 that are snap-connected with each other can be shielded by the second housing 21, thereby helping to make the outer surface of the aerosol generating device 100 have good consistency.

[0067] In some embodiments, the storage assembly 1 is configured to be snap-connected with the main assembly 2 when located at the second position, so that the storage assembly 1 can be kept at the second position.

[0068] Further, at least part of the storage assembly 1 can be located in the receiving cavity when the storage assembly 1 is located at the second position.

[0069] More specifically, reference can be made to Figure 7 At the second position, the second housing 21 can be snap-connected with the first housing 11, so that the storage assembly 1 can be kept at the second position.

[0070] At the second position, at least part of the first housing 11 can be located in the receiving cavity, so that the first housing 11 can be snap-connected with the second housing 21 inside the second housing 21. When the first housing 11 is snap-connected with the second housing 21 at the second position, the snap-connection part can be shielded by the second housing 21.

[0071] In some embodiments, reference can be made to Figure 1 The first housing 11 is provided with a protrusion 13, and the second housing 21 is provided with a first recess 241 and a second recess 242. When the storage assembly 1 is located at the first position, the protrusion 13 is located in the first recess 241, so that the first housing 11 is snap-connected with the second housing 21. When the storage assembly 1 is located at the second position, the protrusion 13 is located in the second recess 242, so that the first housing 11 is snap-connected with the second housing 21. Thus, one protrusion 13 corresponds to one first recess 241 and one second recess 242. When the protrusion 13 is located in the first recess 241, the corresponding second recess 242 is vacant. When the protrusion 13 is located in the second recess 242, the corresponding first recess 241 is vacant.

[0072] The second housing 21 further comprises a first slot wall 2411 defining part of the boundary of the first recess 241. The first slot wall 2411 extends obliquely towards the second recess 242, so that the storage assembly 1 can be moved from the first position to the second position, and so that the protrusion 13 can be moved from the first recess 241 to the second recess 242.

[0073] In some embodiments, the first position and the second position are arranged along the longitudinal direction, so that the storage assembly 1 can be moved from the first position to the second position along the longitudinal direction. The storage assembly 1 can be connected to the main assembly 2 along the longitudinal direction. In the embodiment as shown in Figure 1 At least part of the storage assembly 1 can be kept in the receiving cavity from the end of the second housing 21 along the longitudinal direction.

[0074] In some embodiments, the storage assembly 1 is configured to be kept at the first position, so that the first position forms a first keeping position.

[0075] For example, the second housing 21 can further include a second slot wall 2412 defining a part of the boundary of the first recess 241, and the first slot wall 2411 is arranged opposite to the second slot wall 2412, and thus the first slot wall 2411 is located between the second slot wall 2412 and the second recess 242. The second slot wall 2412 can be arranged such that the included angle between the second slot wall 2412 and the longitudinal direction is greater than the included angle between the first slot wall 2411 and the longitudinal direction, so that the resistance provided by the first slot wall 2411 to the protrusion 13 when the protrusion 13 moves from the first recess 241 towards the second recess 242 is less than the resistance provided by the second slot wall 2412 to the protrusion 13 when the protrusion 13 moves from the first recess 241 away from the second recess 242. In other words, the force for separating the storage assembly 1 from the main assembly 2 can be arranged to be greater than the force for moving the storage assembly 1 from the first position to the second position.

[0076] Obviously, the smaller the included angle between the first slot wall 2411 and the longitudinal direction, the smaller the resistance provided by the first slot wall 2411 to the protrusion 13 when the protrusion 13 moves from the first recess 241 towards the second recess 242, but if the included angle between the first slot wall 2411 and the longitudinal direction is too small, it is not conducive to keeping the protrusion 13 in the first recess 241, and thus it is not conducive to keeping the storage assembly 1 in the first position. Therefore, preferably, the included angle between the first slot wall 2411 and the longitudinal direction is between 20° and 45°, and more preferably, the included angle between the first slot wall 2411 and the longitudinal direction is between 25° and 30°.

[0077] In some embodiments, the storage assembly 1 is configured to be inseparable from the main assembly 2 after being connected to the main assembly 2, or the storage assembly 1 is configured to be always connectable to the main assembly 2, or at least part of the storage assembly 1 is configured to be non-removably retained in the receiving cavity after the storage assembly 1 is connected to the main assembly 2.

[0078] Therefore, in some examples, a first retaining position is arranged in the receiving cavity, and the storage assembly 1 can be retained in the first retaining position after being connected to the main assembly 2. When the storage assembly 1 is in the first retaining position, the storage assembly 1 cannot be removed from the receiving cavity.

[0079] More specifically, in some examples, the included angle between the second slot wall 2412 and the longitudinal direction can be substantially 90°, or the second slot wall 2412 can be formed in a hook shape to increase the resistance provided by the second slot wall 2412 to the protrusion 13 when the protrusion 13 moves from the first recess 241 away from the second recess 242. At the same time, the snap connection between the protrusion 13 and the second housing 21 when the protrusion 13 is in the first recess 241 can be non-elastic. Of course, other ways can also be used to make the storage assembly 1 always connectable to the main assembly 2 and inseparable from the main assembly 2.

[0080] In some embodiments, the storage assembly 1 is configured to be irreversibly moved from the first position to the second position, such that the storage assembly 1 cannot be returned to the first position after being moved from the first position to the second position, and cannot be disengaged from the second position either.

[0081] Based on this, in some examples, the second housing 21 can further include a third slot wall 2421 and a fourth slot wall that define part of the boundary of the second slot 242. The third slot wall 2421 and the fourth slot wall are oppositely arranged in the longitudinal direction, and the third slot wall 2421 is located between the first slot 241 and the fourth slot wall. The angle between the third slot wall 2421 and the longitudinal direction can be substantially 90°, or the third slot wall 2421 can be formed in a hook shape to increase the resistance of the protrusion 13 moving out of the second slot 242 in the direction towards the first slot 241. At the same time, the snap connection between the protrusion 13 and the second housing 21 when the protrusion 13 is located in the second slot 242 can be non-elastic.

[0082] In some embodiments, the storage assembly 1 is configured to be maintained in the second position, such that the second position forms a second holding position.

[0083] For example: when the protrusion 13 is located in the second slot 242, the protrusion 13 is located between the third slot wall 2421 and the fourth slot wall, and the fourth slot wall can support the protrusion 13 to prevent the protrusion 13 from disengaging from the second slot 242 in the direction away from the first slot 241. At the same time, the third slot wall 2421 can prevent the protrusion 13 from exiting the second slot 242 in the direction towards the first slot 241.

[0084] The second slot 242 can have the same shape structure as the first slot 241. The second slot 242 can have the same size as the first slot 241. Of course, the angle between the fourth slot wall and the longitudinal direction can also be substantially 90°.

[0085] In some embodiments, one of the first housing 11 and the second housing 21 is provided with a sliding groove 14, and the other is provided with a sliding block 25 that can be slidably connected with the sliding groove 14 to slide along the sliding groove 14. The protrusion 13 is configured to move into the first slot 241 from the end of the second housing 21 or move into the second slot 242 from the first slot 241 when the sliding block 25 slides along the sliding groove 14.

[0086] The sliding block 25 and the sliding groove 14 are slidably connected to limit the trajectory of the connection between the storage assembly 1 and the main body assembly 2 to ensure that the protrusion 13 can accurately move into the first slot 241 and accurately move from the first slot 241 to the second slot 242.

[0087] In some embodiments, the sliding block 25 is provided with a protrusion 251, and the sliding groove 14 is provided with a groove 141 that can be slidably connected with the protrusion 251 to slide along the sliding groove 14. Figure 1In the shown embodiment, the inner wall of the second housing 21 is provided with a longitudinally extending strip-shaped sliding block 25, and the outer wall of the first housing 11 is provided with a longitudinally extending sliding groove 14. The proximal end of the second housing 21 is open, and the storage assembly 1 can be held in the second housing 21 from the proximal end of the second housing 21. The sliding block 25 can extend to the proximal end of the second housing 21.

[0088] On the same side wall of the second housing 21, two first grooves 241 can be located on opposite sides of the sliding block 25, and the two first grooves 241 can be symmetrically arranged with the central axis of the sliding block 25 as the axis of symmetry. Each first groove 241 can have a corresponding second groove 242.

[0089] At least two side walls of the second housing 21 can be provided with first grooves 241, so that the first grooves 241 can have multiple. The two side walls of the second housing 21 can be oppositely arranged, but are not limited thereto.

[0090] In some embodiments, not shown, the first housing can be provided with a first protrusion and a second protrusion, and the second housing can be provided with a first groove corresponding to the first protrusion and a second groove corresponding to the second protrusion. When the storage assembly is in the first position, the first protrusion is located in the first groove, so that the storage assembly is snap-connected with the main assembly, and at this time, the second protrusion is located outside the second groove; when the storage assembly is in the second position, the first protrusion is moved out of the first groove, and the second protrusion is located in the second groove, so that the storage assembly is snap-connected with the main assembly.

[0091] In some embodiments, not shown, one or more protrusions are provided on the second housing, and one or more grooves are provided on the first housing. By matching the grooves with the corresponding protrusions, the storage assembly is snap-connected with the main assembly in the first position and in the second position.

[0092] In some embodiments, reference can be made to Figure 1 , Figure 3 and Figure 6 The main assembly 2 further includes a third housing 26 provided in the second housing 21, the third housing 26 has a second storage cavity 261 for storing aerosol generating substrate, and the flow guide 23 is connected to the third housing 26, and the second storage cavity 261 is in fluid communication with the flow guide 23 and the atomization core 22. The third housing 26 can define part of the boundary of the receiving cavity, and the third housing 26 can support the storage assembly 1 when the storage assembly 1 is in the second position.

[0093] In some embodiments, before the storage assembly 1 is located at the second position, no aerosol generating substrate is stored in the second storage cavity 261, so that leakage of the aerosol generating substrate in the main assembly 2 can be prevented when the aerosol generating device 100 is stored for a long time. After the storage assembly 1 is located at the second position, the aerosol generating substrate stored in the first storage cavity enters the second storage cavity 261, and at least part of the aerosol generating substrate atomized by the atomizer 22 comes from the second storage cavity 261.

[0094] In some embodiments, before the storage assembly 1 is located at the second position, the aerosol generating substrate is stored in the second storage cavity 261, and the flow guide 23 is sealed, so that leakage of the aerosol generating substrate in the main assembly 2 can be prevented when the aerosol generating device 100 is stored for a long time.

[0095] In some embodiments, after the storage assembly 1 is located at the second position, the first storage cavity is in fluid communication with the second storage cavity 261, and the aerosol generating substrate in the first storage cavity can automatically flow into the second storage cavity 261 and automatically stop flowing into the second storage cavity 261 under dynamic air pressure balance between the first storage cavity and the second storage cavity 261.

[0096] In this embodiment, the flow guide 23 can extend towards the receiving cavity, so that the flow guide 23 can act on the sealing part when the storage assembly 1 is located at the second position, thereby breaking the sealing part.

[0097] In this embodiment, the flow guide 23 can extend towards the receiving cavity, so that the flow guide 23 can act on the sealing part when the storage assembly 1 is located at the second position, thereby breaking the sealing part.

[0098] Preferably, the volume of the first storage cavity is greater than or equal to the volume of the second storage cavity 261.

[0099] The aerosol generating substrate stored in the first storage cavity can include a liquid substrate. The liquid substrate can include a liquid containing a tobacco-containing substance containing a volatile tobacco flavor component, and can also be a liquid containing a non-tobacco substance. The liquid substrate can include water, a medicinal liquid, a solvent, ethanol, a plant extract, a flavoring agent, a flavoring agent, or a vitamin mixture, etc. The flavoring agent can include areca extract, menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent can include components that can provide various flavors or flavors to the user.

Based on the different properties of the liquid substrate, the aerosol generating device can be used in different fields, such as medical, electronic aerosol atomization, etc.

[0100] The aerosol generating substrate stored in the second storage cavity 261 can include a liquid substrate. The aerosol generating substrate stored in the second storage cavity 261 can be the same as the aerosol generating substrate stored in the first storage cavity. The aerosol generating substrate stored in the second storage cavity 261 can be different from the aerosol generating substrate stored in the first storage cavity, so that the aerosol generating substrate stored in the first storage cavity can mix with the aerosol generating substrate stored in the second storage cavity 261 to physically react or chemically react after entering the second storage cavity 261.

[0101] In some embodiments, with reference to Figure 3 and Figure 4 , the storage assembly 1 further includes a liquid storage cotton, at least part of the liquid substrate in the first storage cavity is held in the liquid storage cotton 3, and the liquid storage cotton 3 is arranged to prevent the liquid substrate from leaking. It is optional for the storage assembly 1 to include the liquid storage cotton 3.

[0102] In some embodiments, with reference to Figure 3 and Figure 4 , the main body assembly 2 further includes a liquid storage cotton 3, at least part of the liquid substrate in the second storage cavity 261 is held in the liquid storage cotton 3, and the liquid storage cotton 3 is arranged to prevent the liquid substrate from leaking. It is optional for the main body assembly 2 to include the liquid storage cotton 3.

[0103] In some embodiments, with reference to Figure 3 , the atomization core 22 is capable of absorbing the liquid substrate and guiding the liquid substrate into the atomization range of the heating element; the heating element is used to atomize at least part of the liquid substrate on the liquid absorbing element to form an aerosol. The heating element can be combined with the liquid absorbing element, so that the heating element can form an integral whole with the liquid absorbing element.

[0105] In some embodiments, the atomization core 22 includes an ultrasonic element capable of high-frequency vibration under ultrasonic driving, so that the atomization core 22 can atomize the aerosol generating substrate to form an aerosol by ultrasonic vibration.

[0106] In some embodiments, the storage assembly 1 is at least partially held in the second housing 21 when the storage assembly 1 is located at one of the first position and the second position. When the storage assembly 1 is located at the first position, the storage assembly 1 can be arranged to be spaced apart from the third housing 26, and when the storage assembly 1 is located at the second position, the storage assembly 1 can be supported by the third housing 26.

[0107] In some embodiments, referring to Figure 3 The aerosol-generating device 100 further comprises a power source 5 electrically connected with the atomizing core 22, the power source 5 is configured to provide electric power so that the atomizing core 22 atomizes the aerosol-generating substrate to generate aerosol. The power source 5 can be any suitable battery, for example, can be a lithium battery.

[0108] The third shell 26 further has a holding cavity in which at least a part of the power source 5 is held. Therefore, the power source 5 can be assembled into the second shell 21 as a whole with the third shell 26.

[0109] In some embodiments, referring to Figure 1 , Figure 3 and Figure 6 The main body assembly 2 further comprises a second air conduit 27 fluidly connected with the atomizing core 22, the second air conduit 27 is configured to guide the aerosol generated by the atomizing core 22 atomizing the aerosol-generating substrate to the air inlet 15 of the aerosol-generating device 100. The second air conduit 27 can be connected to the third shell 26, and the second air conduit 27 can be integrally formed with the third shell 26.

[0110] The air passage fluidly connecting the atomizing core 22 and the second air conduit 27 can be a straight air passage. Preferably, the air passage fluidly connecting the atomizing core 22 and the second air conduit 27 is a straight air passage extending in the longitudinal direction. The air passage fluidly connecting the air inlet 15 and the second air conduit 27 can be a straight air passage. Preferably, the air passage fluidly connecting the air inlet 15 and the second air conduit 27 is a straight air passage extending in the longitudinal direction.

[0111] Further, referring to Figure 3 The holding cavity for holding at least a part of the power source 5 is laterally spaced apart from the second storage cavity 261, so that the central axis of the air passage fluidly connecting the atomizing core 22 and the second air conduit 27 is arranged non-collinearly with the central axis of the third shell 26. In order to form a straight air passage between the air inlet 15 and the atomizing core 22 after the storage assembly 1 is connected to the main body assembly 2, the main body assembly 2 and / or the storage assembly 1 further has a fool-proof structure, which makes the storage assembly 1 need to be connected to the main body assembly 2 in a preset orientation or angle.

[0112] In embodiments as shown in Figure 1 and Figure 9 The third shell 26 is provided with a boss 262, the boss 262 is arranged in the second shell 21 deviated from the central axis of the second shell 21, so that the space in the second shell 21 for receiving the storage assembly 1 is an asymmetric space, for example, the boss 262 can be arranged adjacent to the side wall of the second shell 21.

[0113] The first housing 11 can include a first portion 111 and a second portion 112, which is hidden in the second housing 21 when the storage assembly 1 is in the second position. The first portion 111 includes a ledge 1111, and a lateral spacing between the ledge 1111 and the second portion 112 is greater than a lateral spacing between other edges on the first portion 111 and the second portion 112. The ledge 1111 is supported by the boss 262 when the storage assembly 1 is in the second position.

[0114] Therefore, the ledge 1111 needs to be aligned with the boss 262 before the storage assembly 1 is connected with the main assembly 2. Thus, a straight air passage can be formed between the air inlet 15 and the atomizing core 22 after the storage assembly 1 is connected with the main assembly 2.

[0115] In some embodiments, the flow guide 23 has a flow guiding effect, and the aerosol generating substrate in the first storage cavity can flow to the atomizing core 22 along the inside of the flow guide 23 after the seal is broken.

[0116] Specifically, the flow guide 23 includes a tubular portion 231, which fluidly connects the first storage cavity and the atomizing core 22 when the storage assembly 1 is in the second position. The aerosol generating substrate in the first storage cavity can flow into the second storage cavity 261 from the inside of the tubular portion 231, and then flow to the atomizing core 22.

[0117] In some embodiments, the base 12 of the storage assembly 1 includes a flexible member 121. The flexible member 121 can be made of silicone. The flexible member 121 includes a body 1211 and a pierceable membrane 1212, and the pierceable membrane 1212 forms the seal. The body 1211 is provided with a first hole 1213, and the pierceable membrane 1212 is connected to the body 1211 and seals the first hole 1213, so that the aerosol generating substrate in the first storage cavity cannot leak through the first hole 1213. The pierceable membrane 1212 can be pierced by the flow guide 23, and the aerosol generating substrate in the first storage cavity can flow into the main assembly 2 through the first hole 1213 after the pierceable membrane 1212 is pierced.

[0118] Preferably, when the storage assembly 1 is in the second position, the flow guide 23 can form an annular break on the pierceable membrane 1212, which helps to increase the flow area between the first storage cavity and the flow guide 23. At least one part of the break is formed when the pierceable membrane 1212 is pierced by the flow guide 23. In the embodiments as shown in Figure 10 and Figure 11 The part of the break is formed when the pierceable membrane 1212 is pierced by the flow guide 23, and the other part of the break is formed when the flow guide 23 continues to move after piercing the pierceable membrane 1212.

[0119] Further, reference can be made toFigure 8 The puncture-resistant membrane 1212 includes a thick portion 12121 and a thin portion 121212 surrounding the thick portion 12121, such that the thin portion 12122 is more easily punctured than the thick portion 12121. The thin portion 12122 is connected to the body 1211, and the flow guide 23 is configured to puncture the thin portion of the puncture-resistant membrane 1212 when the storage component 1 is in the second position. This allows the thick portion 12121 to detach from the body 1211 when the storage component 1 is in the second position.

[0120] To prevent the detached thick portion 12121 from covering the end of the guide member 23, thereby hindering the flow of the aerosol generation matrix in the first storage cavity into the tubular portion 231, in such a way... Figure 10 and Figure 11 In the illustrated embodiment, the flow guide 23 further includes a plurality of sharp portions 232 located at the end of the tubular portion 231, with a gap between adjacent sharp portions 232. When the storage assembly 1 is in the second position, the gap provides fluid communication between the first storage cavity and the tubular portion 231. At this time, the end of the sharp portion 232 supports the thick portion 12121 of the membrane 1212, which can pierce the membrane 1212.

[0121] In such Figure 10 In the illustrated embodiment, the two sharp portions 232 are a first sharp portion 2321 and a second sharp portion 2322, respectively. When the storage component is in the second position, at least a portion of the first sharp portion 2321 and at least a portion of the second sharp portion 2322 may both be located in the first storage cavity.

[0122] The first sharp portion 2321 and the second sharp portion 2322 may have the same size. The first sharp portion 2321 and the second sharp portion 2322 may be arranged opposite to each other. The first sharp portion 2321 and the second sharp portion 2322 may have the same shape and structure. The first sharp portion 2321 and the second sharp portion 2322 may be arranged symmetrically. The first sharp portion 2321 and the second sharp portion 2322 may have the same size.

[0123] In such Figure 11 In the illustrated embodiment, the extension length of the first sharp portion 2321 is greater than the extension length of the second sharp portion 2322, allowing the first sharp portion to pierce the thin portion 12122 of the pierceable membrane 1212 before the second sharp portion. The first sharp portion 2321 and the second sharp portion 2322 may also have different shapes and structures. Figure 11 In the embodiment shown, the end of the guide member 23 (including multiple sharp portions 232) forms a fish mouth structure.

[0124] In some embodiments, reference may be made to Figure 3 and Figure 6When the storage assembly 1 is located at one of the first position and the second position, the flow guide 23 is at least partially located in the first hole 1213. Preferably, when the storage assembly 1 is located at the first position, at least part of the flow guide 23 is located in the first hole 1213, but there is a gap between the flow guide 23 and the sealing part or the pierceable membrane 1212. The first hole 1213 has a guiding effect, and can guide the sharp part 232 to accurately pierce the thin part 12122 of the pierceable membrane 1212 during movement of the storage assembly 1 from the first position to the second position.

[0125] In some embodiments, the flexible member 121 can be configured to be Figure 8 The body 1211 of the flexible member 121 is further provided with a second hole 1214. The storage assembly 1 further comprises an air inlet 15 and a first air guide tube 16 in fluid communication with the air inlet 15. An end of the first air guide tube 16 is fitted into the second hole 1214 in an interference fit, so that a sealed connection is formed between the first air guide tube 16 and the flexible member 121, to prevent leakage of aerosol generating substrate in the first storage cavity from the second hole 1214.

[0126] The second air guide tube 27 in the main assembly 2 is configured to be located outside the second hole 1214 when the storage assembly 1 is located at the first position, and to be fitted into the second hole 1214 in an interference fit and in fluid communication with the first air guide tube 16 when the storage assembly 1 is located at the second position. Thus, when the storage assembly 1 is located at the second position, a sealed connection is formed between the second air guide tube 27 and the flexible member 121, to prevent leakage of aerosol from the second hole 1214.

[0127] It should be noted that the air inlet 15 of the aerosol generating device 100 is optionally provided on the storage assembly 1. In other embodiments, the aerosol generating device 100 can further comprise a mouthpiece assembly, and the air inlet 15 is provided on the mouthpiece assembly.

[0128] It should be noted that the second air guide tube 27 is optionally located outside the second hole 1214 when the storage assembly 1 is located at the first position, and in other embodiments, the second air guide tube 27 can be located inside the second hole 1214 when the storage assembly 1 is located at the first position.

[0129] In some embodiments, the flow guide 23 is integrally formed with the third housing 26.

[0130] In some embodiments of the present application, when it is necessary to integrally store the aerosol generating device 100, the storage assembly 1 is connected to the main assembly 2, so that the storage assembly 1 is maintained at the first position. When it is necessary to use the aerosol generating device 100, the user can press the storage assembly 1, so that the storage assembly 1 is moved from the first position to the second position, and the storage assembly 1 is thus maintained at the second position.

[0131] It should be noted that the above-mentioned embodiments illustrate rather than limit the application, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims.
