DETAILED DESCRIPTION

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0045] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] The aerosol generating device generally includes a housing component and an extractor component, wherein the extractor component is installed in the housing component, and the extractor component is used to receive and heat the aerosol generating substrate. However, in the prior art, in order to improve the convenience of disassembly and assembly of the extractor component in the housing component, the extractor component is designed to be detached from the housing component by simply pressing a button on the outside of the housing component, which results in the user easily accidentally touching the button when using the aerosol generating substrate, causing the extractor component to be extracted along with the aerosol generating substrate, thus affecting the user's experience.

[0048] In order to solve the above problems, the embodiment of the present application provides an aerosol generating device 1 and an aerosol generating system, wherein a dust cover assembly 300 is arranged 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. The dust cover assembly 300 in the first position can play a dustproof role, and the dust cover assembly 300 in the second position can form a limiting fit with the shell assembly 100 along the first direction X, and the first direction X is the plugging 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 limiting 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.

[0049] See also Figure 1 and Figure 2 , the aerosol generating system provided in the embodiment of the present application is now described. The aerosol generating system comprises an aerosol generating device 1 and an aerosol generating substrate 2 contained in the aerosol generating device 1. The aerosol generating device 1 is used to contain and heat and atomize the aerosol generating substrate 2 to form an aerosol for the user to inhale.

[0050] The aerosol-generating substrate 2 may be a solid substrate, which may include one or more of powders, particles, fragments, strips, or flakes of one or more plant leaves such as tobacco, herb leaves, tea leaves, and mint leaves; or, the solid substrate may contain additional volatile aroma compounds to be released when the substrate is heated. Of course, the aerosol-generating substrate 2 may also be a liquid substrate or a paste substrate, such as oils or liquid medicines with added aroma components.

[0051] Please also read Figure 2 , Figure 3 , Figures 5 to 8 , the aerosol generating device 1 provided in the embodiment of the present application is now described.

[0052] The aerosol generating device 1 comprises a shell assembly 100, an extractor assembly 200 and a dust cover assembly 300; the shell assembly 100 defines a mounting cavity 130; the extractor assembly 200 is inserted into the mounting cavity 130 along a first direction X; the extractor assembly 200 defines a receiving cavity 2111 for receiving 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 a first position, the dust cover assembly 300 covers an outer port of the receiving cavity 2111; when the dust cover assembly 300 is in a second position, the dust cover assembly 300 avoids the outer port and forms a limit fit with the shell assembly 100 along the first direction X.

[0053] 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.

[0054] The first direction X is the plugging direction of the extractor assembly 200 , and 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 .

[0055] The dust cover assembly 300 is movably disposed on the extractor assembly 200, and the dust cover assembly 300 has a first position and a second position on the extractor assembly 200. Figure 5 As shown, 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, and the dust cover assembly 300 can prevent external dust from entering the accommodating chamber 2111; please refer to Figure 1 and Figure 2 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. Therefore, even if the user unlocks the extractor assembly 200 due to accidental touch during use, due to the limiting of the shell assembly 100, the extractor assembly 200 will not be brought out by the aerosol generating matrix 2.

[0056] 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, so as to ensure 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 limited 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.

[0057] In one embodiment, see Figure 2 and Fig.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 along the positive direction of the first direction X, and the extractor assembly 200 is withdrawn from the installation cavity 130 along 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 along 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 being separated from the shell assembly 100 in the reverse direction of the first direction X, and preventing the extractor assembly 200 from being separated from the shell assembly 100 in the reverse direction of the first direction X.

[0058] In one embodiment, see Fig.11 A second limiting portion 314 is respectively provided on two opposite sides of the dust cover assembly 300, and a first limiting portion 140 is respectively provided on two opposite sides of the housing assembly 100. The two first limiting portions 140 and the two second limiting portions 314 respectively form limiting cooperation.

[0059] In one embodiment, see Fig.11 The shell assembly 100 is provided with a first protrusion protruding inwardly, and the side of the dust cover assembly 300 is provided with a second protrusion protruding outwardly. 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 blocking the second protrusion from moving in the opposite direction of the first direction X.

[0060] In one embodiment, see Figure 2 and Figure 5 , the dust cover assembly 300 is slidably disposed on the extractor assembly 200, specifically, the dust cover assembly 300 and the extractor assembly 200 are distributed along the first direction X, the dust cover assembly 300 is disposed on the opposite side of the extractor assembly 200 along the first direction X, and 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 can be understood that in other embodiments of the present application, the above-mentioned dust cover assembly 300 can also be rotatably disposed on the extractor assembly 200, which is not limited here.

[0061] In one embodiment, see Figure 2 , Figure 5 and Fig.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.

[0062] In one embodiment, see Figure 2 , Figures 5 to 8 The extractor assembly 200 includes an extractor 210, the extractor 210 includes a receiving portion 211 and a mounting portion 212, the receiving cavity 2111 is formed in the receiving portion 211, the mounting portion 212 is connected to the outer wall of the receiving portion 211, and the dust cover assembly 300 is slidably connected to the mounting portion 212. For details, please refer to Figure 5 , the dust cover assembly 300 slides to the top of the receiving portion 211 to cover the accommodating cavity 2111 when in the first position; please refer to Figure 2 and Figure 3 When in the second position, the dust cover assembly 300 slides to the top of the mounting portion 212 and avoids the accommodating cavity 2111 , so that the aerosol generating substrate 2 can be inserted into the accommodating cavity 2111 .

[0063] In one embodiment, see Figure 6 The installation cavity 130 also includes a first cavity portion 131 and a second cavity portion 132 . The first cavity portion 131 is roughly cylindrical and is used to accommodate the accommodating portion 211 . The second cavity portion 132 is connected to the top side of the first cavity portion 131 , and is used to accommodate the installation portion 212 .

[0064] In one embodiment, see Figure 3 , Figure 59, a cover plate 220 is installed on the mounting portion 212, and the cover plate 220 and the mounting portion 212 are enclosed to form a limiting groove 230; the dust cover assembly 300 includes a sliding member 310 slidably arranged 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, through the arrangement of the limiting groove 230 and the plug-in member 320, the dust cover assembly 300 and the extractor assembly 200 can be arranged to intersect with each other along the first direction X, that is, the extractor assembly 200 and the dust cover assembly 300 are formed along the first direction X. The structural limitation can ensure the sliding stability of the dust cover assembly 300 on the one hand, and on the other hand, the housing assembly 100 can limit the dust cover assembly 300 along the first direction X, and can also achieve the structural limitation of the extractor assembly 200 along the first direction X.

[0065] 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.

[0066] For details, please refer to Figure 3 and Fig.10 The sliding member 310 is provided with a boss 311 on one side facing the plug-in member 320, and the plug-in member 320 is provided with a sleeve portion 321 corresponding to the boss 311, and the sleeve portion 321 is sleeved outside the boss 311. The sliding member 310 and the plug-in member 320 are locked by screws 340. In addition, the sliding member 310 located at the first position is formed with an arc-shaped baffle 312, and the arc-shaped baffle 312 is used to shield the side of the plug-in member 320 facing the accommodating cavity 2111, so that the overall exposed part of the dust cover assembly 300 located at the first position is neat and beautiful.

[0067] In one embodiment, see Figures 6 to 8 , the first cross section of the receiving portion 211 is circular, the first cross section of the mounting portion 212 is waist-shaped, and the first cross section is a cross section 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 just oppositely arranged, and the surface profiles of the two are similar; when the dust cover assembly 300 is in the second position, a part of the dust cover assembly 300 is blocked above the receiving portion 211, and a part is supported on the mounting portion 212.

[0068] In one embodiment, see Fig. 9 and Fig.10The cover plate 220 is provided with a first guide portion 221, and the dust cover assembly 300 is provided with a second guide portion 313. The first guide portion 221 cooperates with the second guide portion 313 along the second direction Y, thereby guiding the dust cover assembly 300 to slide along the second direction Y.

[0069] In one embodiment, see Fig. 9 and Fig.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 slide grooves formed on the sliding member 310, the slide grooves extend along the second direction Y, and the two sliders are slidably disposed in the two slide grooves respectively.

[0070] In one embodiment, see Figure 3 , Figure 5 and Figure 8 The dust cover assembly 300 also includes a decorative cover 330, which is arranged 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 shell 110), so that the overall appearance of the entire aerosol generating device 1 is consistent.

[0071] In one embodiment, see Figure 3 and Figure 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 set in the first position, the first magnetic member 350 and the second magnetic member 240 repel each other to keep the dust cover assembly 300 in the first position; when the dust cover assembly 300 slides a first preset distance to the second position, the second magnetic member 240 attracts the first magnetic member 350 to make the dust cover assembly 300 slide and remain in the second position. That is, through the arrangement of the first magnetic member 350 and the second magnetic member 240, the dust cover assembly 300 can be kept in the first position and the second position after sliding, and will not slide during use, thereby ensuring the stability of the dust cover assembly 300.

[0072] In one embodiment, see Figure 3 and Figure 5The first magnetic member 350 is placed along the first direction X, and the first magnetic member 350 has a first magnetic pole end 351 and a second magnetic pole end 352 which are arranged opposite to each other along the first direction X; the second magnetic member 240 is placed along the second direction Y, and the second magnetic member 240 has a third magnetic pole end 241 and a fourth magnetic pole end 242 which are 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, so as to push the dust cover assembly 300 in the direction 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 in the direction of 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 attraction to the second magnetic pole end 352, so as 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 attraction, the dust cover assembly 300 remains in the second position.

[0073] 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 here.

[0074] In this embodiment, the position of the dust cover assembly 300 is limited by the attraction and repulsion between the first magnetic member 350 and the second magnetic member 240, and the structure is simple. It can be understood that in other embodiments of the present application, magnetic members may not be provided, but a buckle structure may be used as other limiting structures to limit the position of the dust cover assembly 300, which is not the only limitation here.

[0075] 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 locking with screws 340, plugging or bonding, which is not limited here.

[0076] In one embodiment, see Figure 4, a locking assembly 400 for limiting the position of the extractor assembly 200 along the first direction X is installed on the housing assembly 100, and the locking assembly 400 can be unlocked by pressing the locking assembly 400 outside the housing assembly 100. Among them, through the setting of the locking assembly 400, when the extractor assembly 200 is inserted into the installation cavity 130 in the positive direction of the first direction X, the extractor assembly 200 can be locked in the installation cavity 130 by the locking assembly 400, so as to prevent the extractor assembly 200 from being taken out along with the aerosol generating matrix 2 during use. At the same time, the locking assembly 400 only needs to be pressed outside the housing assembly 100 to unlock, and the operation is simple, and due to the limiting effect between the dust cover assembly 300 and the housing assembly 100, even if the user accidentally touches the locking assembly 400 during use, the extractor assembly 200 will not be taken out along with the aerosol generating matrix 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 herein.

[0077] In one embodiment, see Figure 4 The locking assembly 400 includes a swinging member 410, a torsion spring 420 and a driving member 430. The swinging member 410 is swingably arranged on the shell assembly 100, and the swinging member 410 has a first end 411 and a second end 412 arranged opposite to each other; the torsion spring 420 is connected to the swinging member 410, and the torsion spring 420 is used to keep the first end 411 of the swinging member 410 in a position connected to the extractor assembly 200; the driving member 430 is installed on the shell assembly 100, and the driving member 430 is in contact with the second end 412 of the swinging member 410. Pressing the driving member 430 can drive the swinging member 410 to swing, so that the first end 411 of the swinging member 410 is separated from the extractor assembly 200.

[0078] The torsion spring 420 has a rotational elastic force. In the initial state, the torsion spring 420 has a driving force for the swing member 410 to rotate in a clockwise direction (clockwise is used as an example in this application), so that the swing member 410 rotates clockwise, and the first end 411 of the swing member 410 is close to the extractor assembly 200 and connected with the extractor assembly 200. At the same time, due to the driving force of the torsion spring 420, the swing member 410 is kept in a state of being connected with the extractor 210, thereby limiting the extractor assembly 200 along the first direction X. When the user presses the driving member 430 outside the housing assembly 100, the driving member 430 pushes the second end 412, so that the swing member 410 overcomes the driving force of the torsion spring 420 and rotates counterclockwise, and the swing 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.

[0079] In one embodiment, see Figure 4 The first end 411 is formed with a hook 413, and a block 213 is formed on the outer wall of the extractor assembly 200. When the first end 411 approaches the extractor assembly 200, the hook 413 is hooked on the opposite side of the block 213 along the first direction X, thereby preventing the extractor assembly 200 from being separated from the housing assembly 100 along the opposite side of the first direction X through the hook 413. It can be understood that in other embodiments of the present application, the first end 411 and the extractor assembly 200 can also form a plug-in fit, which is not the only limitation here.

[0080] In one embodiment, see Figure 4 The locking assembly 400 also includes a rotating shaft 440, which is installed on the housing assembly 100, the swinging member 410 is rotatably sleeved on the rotating shaft 440, the torsion spring 420 is sleeved on the rotating shaft 440, one end of the torsion spring 420 is fixedly connected to the rotating shaft 440, and the other end of the torsion spring 420 is fixedly connected to the swinging member 410.

[0081] In one embodiment, see Fig.12 and Fig.13 The housing assembly 100 is also provided with an ejection assembly 500 for ejecting the unlocked extractor assembly 200 in the opposite direction of the first direction X. The setting of the ejection assembly 500 enables the extractor assembly 200 to be ejected in time when the user presses to unlock the extractor assembly 200, without requiring the user to press to unlock the extractor assembly 200 with one hand, and at the same time, in order to avoid the locking assembly 400 from rebounding, the ejection assembly 500 needs to be quickly taken out with the other hand, that is, the difficulty of disassembling the extractor assembly 200 is reduced, and the convenience of disassembling the extractor assembly 200 is improved.

[0082] In one embodiment, see Fig.12 and Fig.13 The pop-up 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 is in contact with 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 is in contact with the bottom of the extractor assembly 200, and the elastic member 520 is in a stretched state, that is, the elastic member 520 has an elastic pulling force on both the first connecting member 510 and the second connecting member 530. When the locking assembly 400 is unlocked and the elastic pulling force of the elastic member 520 is greater than the gravity of the extractor assembly 200, the elastic member 520 can pop the extractor assembly 200 outward, thereby improving the convenience of disassembly of the extractor assembly 200.

[0083] The first connecting member 510 can be locked and fixed on the housing assembly 100 , or the first connecting member 510 can be clamped and limited in the housing assembly 100 , as long as it is ensured that the first connecting member 510 will not be displaced on the housing assembly 100 .

[0084] The second connecting member 530 abuts against the extractor assembly 200 , specifically, the second connecting member 530 abuts against the bottom of the extractor assembly 200 , so that the extractor assembly 200 can be pushed upwards and can also be quickly separated from the extractor assembly 200 .

[0085] In one embodiment, see Fig.12 The elastic member 520 is a cylindrical spring. The elastic member 520 extends along the first direction X. The elastic member 520 exerts a pulling force along the first direction X on the extractor assembly 200 .

[0086] In one embodiment, see Fig.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, so as to limit the ejection of the extractor assembly 200 and prevent the extractor assembly 200 from being ejected too violently by the ejection assembly 500 due to excessive elastic force of the ejection assembly 500.

[0087] For details, please refer to Fig.12 A first limit block 214 is formed on the surface of the extractor assembly 200. When the extractor assembly 200 is popped out by the pop-up assembly 500 to a second preset distance, 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.

[0088] In one embodiment, see Fig.12 The limiting member 600 includes a connecting portion 610 and two second limiting blocks 620. The connecting portion 610 is U-shaped. The two second limiting blocks 620 are respectively installed at the two ends of the connecting portion 610. The two second limiting blocks 620 are respectively arranged at the opposite sides of the swinging member 410. A first limiting block 214 is arranged on the outer wall of the extractor assembly 200. The first limiting block 214 is respectively arranged corresponding to the two second limiting blocks 620. When the extractor assembly 200 is ejected outward, the first limiting block 214 can abut against the two second limiting blocks 620 respectively.

[0089] In one embodiment, see Figure 2The shell assembly 100 includes a shell 110 and a mounting frame 120. The extractor assembly 200, the locking assembly 400 and the pop-up assembly 500 are all installed on the mounting frame 120. The shell 110 is sleeved on the outside of the mounting frame 120. A through hole is formed in the shell 110 at a position corresponding to the driving member 430 so that the driving member 430 is exposed.

[0090] In one embodiment, see Figure 2 and Figure 5 The extractor assembly 200 also includes a heating structure 250, which is disposed in the accommodating cavity 2111. When the aerosol generating substrate 2 is inserted into the accommodating cavity 2111, the heating structure 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.

[0091] In one embodiment, see Figure 2 and Figure 5 The aerosol generating device 1 further comprises an atomizing assembly 700, the extractor assembly 200 is connected to the air outlet end of the atomizing assembly 700, the atomizing assembly 700 is used to heat the atomizing medium to form an aerosol, and the extractor assembly 200 heats the aerosol generating substrate 2. The first aerosol generated by the atomizing medium enters the aerosol generating substrate 2 from the bottom end of the aerosol generating substrate 2, the heating assembly heats the aerosol generating substrate 2 and the first aerosol together, and the second aerosol generated by the heating of the aerosol generating substrate 2 is inhaled by the user together with the first aerosol formed by the atomizing assembly 700, so as to provide the user with a different absorption taste.
