[0046] An aerosol-generating device generally includes a housing assembly and an extractor assembly. The extractor assembly is mounted within the housing assembly and is used to house and heat the aerosol-generating substrate. However, in the prior art, to improve the ease of assembly and disassembly of the extractor assembly within the housing assembly, the extractor assembly is designed to be removed from the housing assembly by simply pressing a button on the outside of the housing assembly. This makes it easy for users to accidentally press the button when using the aerosol-generating substrate, causing the extractor assembly to be extracted along with the aerosol-generating substrate, thus affecting the user experience.

[0047] In order to solve the above problems, the embodiment of the present application provides an aerosol generating device 1 and an aerosol generating system, by arranging a dust cover assembly 300 on the extractor assembly 200, and the dust cover assembly 300 has two positions, a first position and a second position, in the extractor assembly 200. When the dust cover assembly 300 is in the first position, it can play a dust-proof role. When the dust cover assembly 300 is in the second position, it can form a limited fit with the shell assembly 100 along the first direction X. The first direction X is the plug-in direction of the aerosol generating matrix 2. Therefore, even if the user accidentally touches the button during inhalation to unlock the extractor assembly 200, due to the limitation of the dust cover assembly 300 by the shell assembly 100, the extractor assembly 200 will not be taken out together with the aerosol generating matrix 2, thereby improving the user experience.

[0048] Referring to Figures 1 and 2 , an aerosol generating system provided in an embodiment of the present application will now be described. The aerosol generating system includes an aerosol generating device 1 and an aerosol generating substrate 2 housed within the aerosol generating device 1. The aerosol generating device 1 is configured to receive and heat and atomize the aerosol generating substrate 2 to form an aerosol for inhalation by the user.

[0049] The aerosol-generating substrate 2 can be a solid substrate, including one or more of powder, granules, fragments, strips, or flakes of one or more plant leaves, such as tobacco, herb leaves, tea leaves, and mint leaves. Alternatively, the solid substrate can contain additional volatile aroma compounds that are released when the substrate is heated. Of course, the aerosol-generating substrate 2 can also be a liquid or paste-like substrate, such as an oil or liquid medicine with added aroma components.

[0050] Please refer to Figures 2, 3, 5 to 8 together, and the aerosol generating device 1 provided in the embodiment of the present application will now be described.

[0051] The aerosol generating device 1 includes a shell assembly 100, an extractor assembly 200 and a dust cover assembly 300; the shell assembly 100 defines an installation cavity 130; the extractor assembly 200 is inserted into the installation cavity 130 along a first direction X; the extractor assembly 200 defines a receiving cavity 2111 for accommodating an aerosol generating matrix 2; the dust cover assembly 300 is movably arranged on the extractor assembly 200; when the dust cover assembly 300 is in the first position, the dust cover assembly 300 covers the external port of the receiving cavity 2111; when the dust cover assembly 300 is in the second position, the dust cover assembly 300 avoids the external port and forms a limited fit with the shell assembly 100 along the first direction X.

[0052] The extractor assembly 200 is inserted into the installation cavity 130 along the first direction X, and when the limit between the extractor assembly 200 and the shell assembly 100 is cancelled, the extractor assembly 200 can also be taken out from the installation cavity 130 along the first direction X.

[0053] The first direction X is the plugging direction of the extractor assembly 200 . The first direction X is also the plugging direction of the aerosol generating substrate 2 relative to the accommodating cavity 2111 , that is, the axial direction of the aerosol generating substrate 2 .

[0054] The dust cover assembly 300 is movably mounted on the extractor assembly 200 and has a first position and a second position. As shown in FIG5 , when the dust cover assembly 300 is in the first position, the dust cover assembly 300 covers the outer opening of the accommodating chamber 2111. In this position, the aerosol-generating substrate 2 cannot be inserted into the accommodating chamber 2111, and the dust cover assembly 300 prevents external dust from entering the accommodating chamber 2111. Referring to FIG1 and FIG2 , when the dust cover assembly 300 is in the second position, the dust cover assembly 300 avoids the outer opening. In this position, the aerosol-generating substrate 2 can be inserted into the accommodating chamber 2111 for inhalation by the user. Furthermore, the dust cover assembly 300 and the housing assembly 100 form a retaining engagement along the first direction X. Therefore, even if the user accidentally unlocks the extractor assembly 200 during use, the retaining engagement of the housing assembly 100 prevents the extractor assembly 200 from being dislodged by the aerosol-generating substrate 2.

[0055] The aerosol generating device 1 in the embodiment of the present application is provided with a dust cover assembly 300 on the extractor assembly 200, and the dust cover assembly 300 is movable on the extractor assembly 200 and has a first position and a second position. When the dust cover assembly 300 is in the first position, the dust cover assembly 300 covers the outer port of the accommodating chamber 2111. At this time, the aerosol generating substrate 2 cannot be inserted into the accommodating chamber 2111. The dust cover assembly 300 can prevent external dust from entering the accommodating chamber 2111, thereby ensuring that the extractor assembly 200 is clean during use. degree; when the dust cover assembly 300 is in the second position, the dust cover assembly 300 avoids the external port. At this time, the aerosol generating matrix 2 can be inserted into the accommodating cavity 2111 for the user to inhale, and at this time the dust cover assembly 300 and the shell assembly 100 form a limiting fit along the first direction X. Even if the user unlocks the extractor assembly 200 due to accidental touch during use, due to the limitation of the shell assembly 100, the extractor assembly 200 will not be brought out by the aerosol generating matrix 2, thereby reducing user usage restrictions and improving user experience.

[0056] In one embodiment, please refer to Figures 2 and 11, the shell assembly 100 is formed with a first limiting portion 140, and the dust cover assembly 300 is formed with a second limiting portion 314; it is assumed that the extractor assembly 200 is inserted into the installation cavity 130 in the positive direction of the first direction X, and the extractor assembly 200 exits the installation cavity 130 in the reverse direction of the first direction X; when the dust cover assembly 300 is in the second position, the first limiting portion 140 is located on the reverse side of the second limiting portion 314 in the first direction X, that is, when the second limiting portion 314 moves in the reverse direction of the first direction X, it will be blocked by the first limiting portion 140, thereby preventing the dust cover assembly 300 from detaching from the shell assembly 100 in the reverse direction of the first direction X, and preventing the extractor assembly 200 from detaching from the shell assembly 100 in the reverse direction of the first direction X.

[0057] In one embodiment, referring to FIG. 11 , a second limiting portion 314 is provided on opposite sides of the dust cover assembly 300 , and a first limiting portion 140 is provided on opposite sides of the shell assembly 100 . The two first limiting portions 140 and the two second limiting portions 314 respectively form limiting cooperation.

[0058] In one embodiment, referring to Figure 11, the shell assembly 100 is provided with a first protrusion protruding inward, and the side of the dust cover assembly 300 is provided with a second protrusion protruding outward. When the second protrusion moves in the opposite direction of the first direction X, the second protrusion abuts against the first protrusion along the first direction X, thereby preventing the second protrusion from moving in the opposite direction of the first direction X.

[0059] In one embodiment, referring to Figures 2 and 5 , the dust cover assembly 300 is slidably mounted on the extractor assembly 200. Specifically, the dust cover assembly 300 and the extractor assembly 200 are arranged along a first direction X. The dust cover assembly 300 is disposed on a side of the extractor assembly 200 opposite to the first direction X. The dust cover assembly 300 can slide on the extractor assembly 200 so that the dust cover assembly 300 has a first position and a second position on the extractor assembly 200. It is understood that in other embodiments of the present application, the dust cover assembly 300 can also be rotatably mounted on the extractor assembly 200, and this is not intended to be the sole limitation herein.

[0060] In one embodiment, referring to Figures 2, 5 and 11, the dust cover assembly 300 is slidably disposed on the extractor assembly 200 along the second direction, and the two first limiting portions 140 are distributed along the third direction Z. The first direction X, the second direction and the third direction Z are perpendicular to each other.

[0061] In one embodiment, referring to Figures 2, 5, and 8, the extractor assembly 200 includes an extractor 210, which includes a receiving portion 211 and a mounting portion 212. A receiving cavity 2111 is formed in the receiving portion 211, and the mounting portion 212 is connected to the outer wall of the receiving portion 211. The dust cover assembly 300 is slidably connected to the mounting portion 212. Specifically, referring to Figure 5, when in the first position, the dust cover assembly 300 slides above the receiving portion 211 to cover the receiving cavity 2111. Referring to Figures 2 and 3, when in the second position, the dust cover assembly 300 slides above the mounting portion 212 and clears the receiving cavity 2111, allowing the aerosol-generating substrate 2 to be inserted into the receiving cavity 2111.

[0062] In one embodiment, referring to FIG6 , the mounting cavity 130 also includes a first cavity 131 and a second cavity 132. The first cavity 131 is generally cylindrical and is used to accommodate the receiving portion 211. The second cavity 132 is connected to the top side of the first cavity 131 and is used to accommodate the mounting portion 212. A positioning ridge 150 is provided on the inner sidewall of the first cavity 131, and a positioning groove 2112 is provided on the outer sidewall of the receiving portion 211. After the receiving portion 211 is installed in the first cavity 131, the positioning ridge 150 is embedded in the positioning groove 2112, ensuring precise positioning of the receiving portion 211. After the receiving portion 211 is installed in the first cavity 131, the positioning ridge 150 is embedded in the positioning groove 2112, ensuring a stable structure.

[0063] In one embodiment, referring to Figures 3, 5, and 10, a cover plate 220 is mounted on the mounting portion 212. The cover plate 220 and the mounting portion 212 form a limiting groove 230. The dust cover assembly 300 includes a sliding member 310 slidably mounted on the cover plate 220, and a plug-in member 320 connected to the sliding member 310 and slidably limited in the limiting groove 230. In this embodiment, the limiting groove 230 and the plug-in member 320 enable the dust cover assembly 300 and the extractor assembly 200 to be interlaced with each other along the first direction X, thereby forming a structural limit between the extractor assembly 200 and the dust cover assembly 300 along the first direction X. This not only ensures the sliding stability of the dust cover assembly 300, but also allows the housing assembly 100 to limit the dust cover assembly 300 along the first direction X, thereby also achieving structural limit for the extractor assembly 200 along the first direction X.

[0064] Specifically, the sliding member 310 and the connector 320 are distributed along the first direction X and fixed to each other. After the connector 320 is inserted into the limiting groove 230, the limiting groove 230 limits the connector 320 along the first direction X, and the connector 320 can slide along the second direction Y in the limiting groove 230.

[0065] Specifically, referring to Figures 3 and 10 , the sliding member 310 has a boss 311 on the side facing the plug connector 320. The plug connector 320 has a socket portion 321 corresponding to the boss 311, which is sleeved onto the outside of the boss 311. The sliding member 310 and the plug connector 320 are secured together by screws 340. Furthermore, when the sliding member 310 is in the first position, a curved baffle 312 is formed. This baffle 312 is used to shield the side of the plug connector 320 facing the accommodating cavity 2111, thereby ensuring that the exposed portion of the dust cover assembly 300 in the first position is neat and aesthetically pleasing.

[0066] In one embodiment, referring to Figures 6 to 8 , the first cross-section of the receiving portion 211 is circular, while the first cross-section of the mounting portion 212 is waist-shaped. The first cross-section is perpendicular to the first direction X. The first cross-section of the dust cover assembly 300 is waist-shaped. When the dust cover assembly 300 is in the first position, the dust cover assembly 300 and the mounting portion 212 are directly opposite each other, and their surface profiles are similar. When the dust cover assembly 300 is in the second position, a portion of the dust cover assembly 300 is located above the receiving portion 211, while a portion is supported by the mounting portion 212.

[0067] In one embodiment, referring to Figures 9 and 10, a first guide portion 221 is provided on the cover plate 220, and a second guide portion 313 is provided on the dust cover assembly 300. The first guide portion 221 and the second guide portion 313 cooperate with each other in the second direction Y, thereby guiding the dust cover assembly 300 to slide along the second direction Y.

[0068] In one embodiment, please refer to Figures 9 and 10, wherein the first guide portion 221 is two spaced-apart sliders formed on the cover plate 220, and the second guide portion 313 is two spaced-apart sliding grooves formed on the sliding member 310, the sliding grooves extend along the second direction Y, and the two sliders are respectively slidably arranged in the two sliding grooves.

[0069] In one embodiment, referring to Figures 3, 5 and 8, the dust cover assembly 300 further includes a decorative cover 330, which is disposed on the top side of the sliding member 310. The decorative cover 330 is waist-shaped, and the material of the decorative cover 330 is the same as the surface material of the shell assembly 100 (specifically, the material of the outer cover 110), so that the overall appearance of the entire aerosol generating device 1 is consistent.

[0070] In one embodiment, referring to Figures 3 and 5 , a first magnetic member 350 is provided on the dust cover assembly 300, and a second magnetic member 240 is provided on the extractor assembly 200. When the dust cover assembly 300 is in the first position, the first magnetic member 350 and the second magnetic member 240 repel each other to maintain the dust cover assembly 300 in the first position. When the dust cover assembly 300 slides a first preset distance toward the second position, the second magnetic member 240 attracts the first magnetic member 350 to slide and maintain the dust cover assembly 300 in the second position. In other words, the arrangement of the first magnetic member 350 and the second magnetic member 240 allows the dust cover assembly 300 to remain in the first and second positions after sliding, without slipping during use, thereby ensuring the stability of the dust cover assembly 300.

[0071] In one embodiment, referring to Figures 3 and 5, the first magnetic member 350 is placed along a first direction X, and the first magnetic member 350 has a first magnetic pole end 351 and a second magnetic pole end 352 arranged opposite to each other along the first direction X; the second magnetic member 240 is placed along a second direction Y, and the second magnetic member 240 has a third magnetic pole end 241 and a fourth magnetic pole end 242 arranged opposite to each other along the second direction Y, the second magnetic pole end 352 and the third magnetic pole end 241 are of the same sex, and the second magnetic pole end 352 and the fourth magnetic pole end 242 are of opposite sex. When the dust cover assembly 300 is in the first position, the second magnetic member 240 is located on the side of the first magnetic member 350 close to the second position, and the second magnetic pole end 352 is adjacent to the third magnetic pole end 241 and repel each other to push the dust cover assembly 300 away from the second position, thereby pushing the dust cover assembly 300 to remain in the first position; when the dust cover assembly 300 is pushed toward the second position by a first preset distance, the first magnetic member 350 is located at the midpoint of the second magnetic member 240 along the second direction Y and close to the second position, so that the fourth magnetic pole end 242 of the second magnetic member 240 begins to have an attractive force on the second magnetic pole end 352 to drive the dust cover assembly 300 to slide toward the second position until the dust cover assembly 300 slides to the second position, and due to the attractive force, the dust cover assembly 300 remains in the second position.

[0072] Optionally, the first magnetic member 350 and the second magnetic member 240 are both permanent magnets. It is understandable that in other embodiments of the present application, the first magnetic member 350 and the second magnetic member 240 may also be electromagnets, which is not the only limitation herein.

[0073] In this embodiment, the dust cover assembly 300 is positioned by the attraction and repulsion between the first magnetic member 350 and the second magnetic member 240, resulting in a simple structure. It is understood that in other embodiments of the present application, magnetic members may not be provided, and instead a snap-fit ​​structure may be used as another limiting structure to position the dust cover assembly 300. This is not intended to be the only limitation herein.

[0074] In one embodiment, the cover plate 220 is fixed to the mounting portion 212 by snapping. It is understandable that in other embodiments, the cover plate 220 can also be connected by means of screws 340, plug-fitting, or bonding, which is not limited here.

[0075] In one embodiment, referring to FIG. 4 , a locking assembly 400 is mounted on the housing assembly 100 for limiting the position of the extractor assembly 200 along the first direction X. Pressing the locking assembly 400 from the exterior of the housing assembly 100 unlocks the lock on the extractor assembly 200. The provision of the locking assembly 400 allows the extractor assembly 200 to be locked within the installation cavity 130 after being inserted into the installation cavity 130 in the forward direction of the first direction X, preventing the extractor assembly 200 from being removed along with the aerosol-generating substrate 2 during use. Furthermore, the locking assembly 400 can be unlocked simply by pressing the exterior of the housing assembly 100, making it easy to operate. Furthermore, due to the limiting effect between the dust cover assembly 300 and the housing assembly 100, even if a user accidentally touches the locking assembly 400 during use, the extractor assembly 200 will not be removed along with the aerosol-generating substrate 2, thereby improving the user experience. It is understandable that in other embodiments of the present application, the locking assembly 400 may also be unlocked by toggling, sliding, or rotating, which is not the only limitation here.

[0076] In one embodiment, referring to Figure 4, the locking assembly 400 includes a locking member 410 and an unlocking switch 430. The locking member 410 is movably arranged on the housing assembly 100. The locking member 410 can extend into the installation cavity 130 and lock with the extractor assembly 200. The unlocking switch 430 is used to control the movement of the locking member 410, and the unlocking switch 430 is exposed outside the housing assembly 100.

[0077] Specifically, the locking member 410 can be provided on the housing assembly 100 in a manner such as, but not limited to, rotational or sliding engagement, so that the unlocking switch 430 can be actuated to control the movement of the locking member 410 to lock or unlock the extractor assembly 200. The unlocking switch 430 is exposed outside the housing assembly 100, making it convenient for the user to actuate the unlocking switch 430 and simplifying operation.

[0078] Then the locking member 410 has a specific locking position and an unlocking position. In the locking position, the locking member 410 is locked with the extractor assembly 200, and the extractor assembly 200 is stably installed in the installation cavity 130; in the unlocking position, the locking member 410 is unlocked from the extractor assembly 200, and the extractor assembly 200 can exit the installation cavity 130 along the first direction X.

[0079] In some embodiments, referring to FIG. 4 , the locking member 410 is provided with a locking portion 413 , and the extractor assembly 200 is provided with a locking fitting portion 213 , and a locking fitting can be formed between the locking portion 413 and the locking fitting portion 213 ; and the movement of the locking member 410 can separate the locking portion 413 from the locking fitting portion 213 to unlock.

[0080] It is understood that the locking member 410 achieves a locking effect by engaging the locking portion 413 with the locking mating portion 213 on the extractor assembly 200. The locking portion 413 and the locking mating portion 213 can specifically adopt a snap-fit ​​structure, that is, one of the locking portion 413 and the locking mating portion 213 includes a snap, and the other includes a slot. Alternatively, the locking portion 413 and the locking mating portion 213 can specifically adopt a plug-in structure, that is, one of the locking portion 413 and the locking mating portion 213 includes a plug, and the other includes a slot.

[0081] In some embodiments, referring to FIG4 , a locking member 410 is extended along a first direction X, and the locking member 410 is rotatably engaged with the housing assembly 100; a locking portion 413 is provided at a first end 411 of the locking member 410, and a second end 412 of the locking member 410 is connected to an unlocking switch 430; the locking assembly 400 further includes an elastic return member 420 for driving the locking member 410 to rotate and reset. Specifically, the elastic return member 420 is connected to the locking member 410, and is used to maintain the first end 411 of the locking member 410 in a position connected to the extractor assembly 200; the unlocking switch 430 is mounted on the housing assembly 100, and is in contact with the second end 412 of the locking member 410. Pressing the unlocking switch 430 can drive the locking member 410 to swing, so that the first end 411 of the locking member 410 is separated from the extractor assembly 200.

[0082] Among them, the elastic return member 420 has a rotational elastic force. In the initial state, the elastic return member 420 has a driving force to rotate the locking member 410 in a clockwise direction (clockwise is taken as an example in this application), so that the locking member 410 rotates clockwise, and the first end 411 of the locking member 410 approaches the extractor assembly 200 and forms a connection with the extractor assembly 200. At the same time, due to the driving force of the elastic return member 420, the locking member 410 remains in a state of connection with the extractor assembly 200, thereby limiting the extractor assembly 200 along the first direction X. When the user presses the unlocking switch 430 outside the shell assembly 100, the unlocking switch 430 pushes the second end 412, so that the locking member 410 overcomes the driving force of the elastic return member 420 and rotates counterclockwise. The locking member 410 drives the first end 411 to swing away from the extractor assembly 200, thereby unlocking the extractor assembly 200, so that the user can take out the extractor assembly 200 in the opposite direction of the first direction X and perform cleaning and maintenance. It can be understood that in other embodiments of the present application, the locking member 410 can also be slidably provided on the housing assembly 100 .

[0083] In some embodiments, the elastic return member 420 is a torsion spring, which can provide elastic force for the locking member 410 to reset again after rotation, so that the locking member 410 has a movement tendency to reset to the locked position again in the unlocked position; then, when the extractor assembly 200 is taken out and installed in the installation cavity 130 again, the locking member 410 can quickly lock the extractor assembly 200.

[0084] In one embodiment, referring to Figure 4, the locking assembly 400 further includes a rotating shaft 440, which is mounted on the housing assembly 100, the locking member 410 is rotatably sleeved on the rotating shaft 440, the elastic return member 420 is sleeved on the rotating shaft 440, one end of the elastic return member 420 is fixedly connected to the rotating shaft 440, and the other end of the elastic return member 420 is fixedly connected to the locking member 410.

[0085] In one embodiment, referring to Figures 12 and 13 , the housing assembly 100 is further provided with an ejection assembly 500 for ejecting the unlocked extractor assembly 200 in the opposite direction of the first direction X. The provision of the ejection assembly 500 allows the user to promptly eject the extractor assembly 200 when the user presses to unlock the extractor assembly 200, without requiring the user to use one hand to unlock the extractor assembly 200 and to use the other hand to quickly remove the ejection assembly 500 in order to prevent the locking assembly 400 from rebounding. This reduces the difficulty of disassembling the extractor assembly 200 and improves the convenience of disassembling the extractor assembly 200.

[0086] In one embodiment, referring to Figures 12 and 13, the pop-up assembly 500 includes an elastic member 520. When the unlocking switch 430 controls the unlocking between the extractor assembly 200 and the housing assembly 100, the elastic member 520 provides elastic force to cause the extractor assembly 200 to pop out of the mounting cavity along the first direction X to a preset position.

[0087] Specifically, the extractor component 200 and the shell component 100 can be separately arranged, and the aerosol generating matrix 2 is arranged in the accommodating cavity 2111 of the extractor component 200; that is, when the aerosol generating matrix 2 is heated for a certain time and the amount of mist generated by it reaches the upper limit, the extractor component 200 can be removed from the shell component 100 separately, so that the aerosol generating matrix 2 can be removed from the extractor component 200 conveniently to replace the new aerosol generating matrix 2; and the residue generated during the heating process of the aerosol generating matrix 2 remains in the extractor component 200. When cleaning, it is only necessary to take out the extractor component 200 for cleaning, which is convenient for cleaning.

[0088] It is understood that the extractor assembly 200 forms a locked fit with the housing assembly 100 through the locking assembly 400. The locking assembly 400 may employ, but is not limited to, locking components such as a snap connector, a plug connector, and a buckle connector to lock the housing assembly 100 and the extractor assembly 200 together. This is not specifically limited herein, but is sufficient to limit the extractor assembly 200 from disengaging from the mounting cavity 130 along a first direction X. The first direction X is the X direction shown in the figure, and the first direction X is parallel to the extension direction of the accommodating cavity 2111. Furthermore, the user can control the unlocking of the extractor assembly 200 from the housing assembly 100 by actuating the unlocking switch 430. That is, the unlocking switch 430 can switch the extractor assembly 200 from a locked state to an unlocked state, allowing the extractor assembly 200 to disengage from the mounting cavity 130 along the first direction X in the unlocked state.

[0089] The elastic member 520 can provide elastic force to cause the extractor assembly 200 to automatically detach from the mounting cavity 130, that is, when the user operates the unlocking switch 430 to control the extractor assembly 200 to unlock, the extractor assembly 200 can immediately automatically pop out of the mounting cavity 130 to a preset position under the elastic force of the elastic member 520, that is, the extractor assembly 200 will partially pop out of the mounting cavity 130, which is very convenient for the user to remove the extractor assembly 200 from the shell assembly 100 by hand.

[0090] Furthermore, the preset position is configured so that the extractor assembly 200 does not completely escape from the mounting cavity 130 , but rather partially pops out of the mounting cavity 130 , making the pop-up structure stable and reliable.

[0091] The elastic member 520 may be, but is not limited to, a tension spring or a compression spring, so as to provide the extractor assembly 200 with an elastic force to separate from the installation cavity 130 .

[0092] For example, the elastic member 520 can be a tension spring, one end of the elastic member 520 is connected to the housing assembly 100, and the other end of the elastic member 520 acts on the extractor assembly 200. Alternatively, the elastic member 520 can be a compression spring, and the elastic member 520 is provided at the bottom end of the extractor assembly 200.

[0093] In one embodiment, referring to Figures 12 and 13, the ejection assembly 500 includes a first connecting member 510, an elastic member 520, and a second connecting member 530. The first connecting member 510 is connected to the housing assembly 100, the second connecting member 530 abuts against the extractor assembly 200, and the elastic member 520 is connected between the first connecting member 510 and the second connecting member 530. When the extractor assembly 200 is installed in the installation cavity 130, the second connecting member 530 abuts against the bottom of the extractor assembly 200, and the elastic member 520 is in a stretched state, that is, the elastic member 520 exerts elastic tension on both the first connecting member 510 and the second connecting member 530. When the locking assembly 400 is unlocked and the elastic tension of the elastic member 520 is greater than the weight of the extractor assembly 200, the elastic member 520 can eject the extractor assembly 200 outward, thereby improving the convenience of disassembling the extractor assembly 200.

[0094] Among them, the elastic member 520 is a tension spring extending in the first direction X, and the first connecting member 510 is arranged at the upper end of the elastic member 520. The first connecting member 510 can be locked and fixed on the shell assembly 100. The first connecting member 510 can also be installed in the shell assembly 100 by means of clamping or screw connection, as long as it is ensured that the first connecting member 510 will not be displaced on the shell assembly 100.

[0095] The second connecting member 530 includes a connecting body 531 and an abutting protrusion 532 protruding toward one side from the connecting body 531, and the abutting protrusion 532 abuts against the bottom end of the extractor assembly 200; referring to Figure 8, when the extractor assembly 200 is installed in the installation cavity 130 of the shell assembly 100, and the extractor assembly 200 is locked with the locking member 410, the elastic member 520 is in a stretched state, that is, the elastic member 520 will provide an upward elastic force to the extractor assembly 200, so that the extractor assembly 200 has a tendency to pop up from the installation cavity 130 upward; referring to Figure 9, when the locking member 410 is unlocked from the extractor assembly 200, the elastic member 520 immediately drives the second connecting member 530 to drive the extractor assembly 200 to pop up.

[0096] For example, the elastic member 520 can be a tension spring, one end of the elastic member 520 is connected to the housing assembly 100, and the other end of the elastic member 520 acts on the extractor assembly 200. Alternatively, the elastic member 520 can be a compression spring, and the elastic member 520 is provided at the bottom end of the extractor assembly 200.

[0097] In one embodiment, referring to Figure 12, a limiting member 600 is installed on the shell assembly 100, and the limiting member 600 is used to buffer and limit the extractor assembly 200 that is ejected to a second preset distance, thereby limiting the ejection of the extractor assembly 200 and preventing the extractor assembly 200 from being ejected too violently by the ejection assembly 500 due to excessive elastic force of the ejection assembly 500.

[0098] Specifically, referring to Figure 12, a first limit block 214 is formed on the surface of the extractor assembly 200. When the extractor assembly 200 is popped out to a second preset distance by the pop-up assembly 500, the first limit block 214 elastically abuts against the limit member 600. At the same time, since the first limit block 214 elastically abuts against the limit member 600, the extractor assembly 200 can be manually taken out.

[0099] In one embodiment, referring to FIG12 , the stopper 600 includes a connecting portion 610 and two second stoppers 620. The connecting portion 610 is U-shaped, and the two second stoppers 620 are respectively mounted at the two ends of the connecting portion 610. The two second stoppers 620 are respectively disposed on opposite sides of the locking member 410. A first stopper 214 is disposed on the outer wall of the extractor assembly 200. The first stopper 214 is disposed correspondingly to the two second stoppers 620. When the extractor assembly 200 is ejected outward, the first stopper 214 can abut against the two second stoppers 620.

[0100] It can be understood that in the process of the extractor assembly 200 being ejected upward from the installation cavity 130 by the elastic force of the elastic member 520, the first limit block 214 and the second limit block 620 abut and rub against each other, which can slow down the ejection speed of the extractor assembly 200 and make the extractor assembly 200 finally stay at the limit position; that is, in the process of the extractor assembly 200 being ejected upward, it is ejected to the preset position by the limiting action of the first limit block 214 and the second limit block 620, and the structure is more stable and reliable.

[0101] Specifically, there is a slight interference fit between the first limit block 214 and the second limit block 620, that is, the user can apply external force to the extractor assembly 200 to make the first limit block 214 pass through the second limit block 620 along the first direction X, and thus completely remove the extractor assembly 200 from the installation cavity 130.

[0102] In some embodiments, the first stopper 214 is made of a flexible material, including at least one of silicone, rubber, and plastic. This effectively increases the friction between the first stopper 214 and the second stopper 620, thereby better securing the extractor assembly 200. Furthermore, the second stopper 620 is made of a flexible material, allowing it to pass through the first stopper 214 in the first direction X under the action of an external force without affecting the complete removal of the extractor assembly 200 from the mounting cavity 130.

[0103] In some embodiments, the distance that the extractor assembly 200 is separated from the mounting cavity 130 along the first direction X is in the range of 3-5 cm, specifically 3 cm, 4 cm, 5 cm, etc.; so that the extractor assembly 200 has sufficient length to escape from the mounting cavity 130, making it convenient for the user to grasp the pop-up part of the extractor assembly 200.

[0104] In one embodiment, referring to FIG2 , the housing assembly 100 includes an outer cover 110 and a main housing 120. The main housing 120 defines the aforementioned mounting cavity 130. The extractor assembly 200, the locking member 410, and the ejection assembly 500 are all mounted on the main housing 120. The outer cover 110 is sleeved onto the exterior of the main housing 120, and the unlocking switch 430 is exposed outside the outer cover 110. Specifically, a through hole is formed in the outer cover 110 corresponding to the position of the unlocking switch 430, so that the unlocking switch 430 is exposed.

[0105] Specifically, the locking member 410 is rotatably mounted on the main housing 120 , and the unlocking switch 430 is exposed outside the outer cover 110 , so that the user can conveniently operate the unlocking switch 430 to control the rotation of the locking member 410 .

[0106] The main shell 120 has a receiving groove, and the elastic member 520 is limitedly set in the receiving groove of the main shell 120. The elastic member 520 can elastically deform along the first direction X in the receiving groove to act on the extractor assembly 200 to move, so that the elastic member 520 acts on the extractor assembly 200 to move stably and smoothly.

[0107] An outer cover 110 is provided outside the main housing 120 to conceal the internal structure and improve the appearance of the product.

[0108] In one embodiment, referring to Figures 2 and 5, the extractor assembly 200 further includes a heating assembly 250, which is disposed in the accommodating cavity 2111. When the aerosol generating substrate 2 is inserted into the accommodating cavity 2111, the heating assembly 250 is disposed around the bottom end of the aerosol generating substrate 2 and is used to heat the bottom end of the aerosol generating substrate 2 to generate an aerosol.

[0109] In one embodiment, referring to Figures 2 and 5, the heating component 250 includes a heating element 251 for heating the aerosol generating substrate 2; the extractor component 200 is formed with a bottom wall 260 at the bottom end of the accommodating cavity 2111, and a notch 261 is formed on the bottom wall 260 to allow the heating element 251 to be inserted into the accommodating cavity 2111.

[0110] Specifically, the aerosol generating matrix 2 is arranged in the accommodating cavity 2111 and abuts against the bottom wall 260. The heating element 251 is specifically a heating sheet. The heating element 251 can be inserted into the aerosol generating matrix 2 to heat the aerosol generating matrix 2. By controlling the heating temperature, the aerosol generating matrix 2 is sufficient to generate aerosol for the user to inhale.

[0111] As can be understood, the heating element 251 is used to convert electrical energy into thermal energy. Referring to FIG2 , the heating element 251 can be a heating plate. The aerosol generating device 1 also includes a power supply assembly 800 , through which the heating element 251 is electrically connected to the power supply assembly 800 , so that the heating element 251 has a heating function.

[0112] In one embodiment, referring to Figures 2 and 5 , the aerosol generating device 1 further includes an atomizing assembly 700. The extractor assembly 200 is connected to the air outlet of the atomizing assembly 700. The atomizing assembly 700 is configured to heat the atomized medium to form an aerosol, and the extractor assembly 200 heats the aerosol generating substrate 2. A first aerosol generated by the atomized medium enters the aerosol generating substrate 2 from its bottom end. The heating assembly heats both the aerosol generating substrate 2 and the first aerosol. A second aerosol generated by the heated aerosol generating substrate 2 is inhaled by the user together with the first aerosol generated by the atomizing assembly 700, providing the user with a different inhalation experience.

[0113] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
