[0023] As shown in FIG. 1 to FIG. 14, an embodiment of this application provides an aerosol generating device, including: a housing 1, a heating element, a battery cell 4, and a bottom cover 2. The housing 1 includes a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. The housing 1 has a near end and a far end that face away from each other in the longitudinal direction. The heating element is configured to heat an aerosol generating substrate to generate an aerosol. The battery cell 4 is configured to provide power to the heating element. The bottom cover 2 at least partially seals the far end of the housing 1 and is detachably connected to the housing 1. The bottom cover 2 is configured to be detached from the housing 1 to open the far end of the housing 1, to allow the battery cell 4 to be taken out of the far end of the housing 1. The bottom cover 2 is capable of being converted between a locked state and an unlocked state, is prevented, in the locked state, from being detached from the housing 1, and is allowed, in the unlocked state, to be detached from the housing 1. The bottom cover 2 is driven by a user to move relative to the housing 1 in the transverse direction, to convert from the locked state to the unlocked state. In the unlocked state, at least a part of the bottom cover 2 protrudes out of the housing 1 in the transverse direction, so that the user is capable of operating the part that is of the bottom cover 2 and that protrudes out of the housing 1, to detach the bottom cover 2 from the housing 1.

[0024] The bottom cover 2 is configured to be detached from the housing 1 to open the far end of the housing 1, to allow the battery cell 4 to be taken out of the far end of the housing 1, so that the battery cell 4 can be replaced with. The bottom cover 2 is capable of being converted between the locked state and the unlocked state, is prevented, in the locked state, from being detached from the housing 1, and is allowed, in the unlocked state, to be detached from the housing 1. Therefore, in the locked state, the bottom cover 2 can be connected to the housing 1, to seal the far end of the housing 1, to prevent a component accommodated inside the housing 1 from being separated from the housing 1. In the unlocked state, the bottom cover 2 can be detached from the housing 1, so that the user can replace the battery cell 4 accommodated inside the housing 1. The bottom cover 2 is driven by the user to move relative to the housing 1 in the transverse direction, to convert from the locked state to the unlocked state. In the unlocked state, at least a part of the bottom cover 2 protrudes out of the housing 1 in the transverse direction, so that the user can operate the part that is of the bottom cover 2 and that protrudes out of the housing 1 to detach the bottom cover 2 from the housing 1. This is convenient for the user to detach the bottom cover 2 from the housing 1, thereby improving user experience.

[0025] It should be noted that the longitudinal direction is a length direction of the aerosol generating device, and the transverse direction may be a thickness direction of the aerosol generating device, or may be a width direction of the aerosol generating device.

[0026] As shown in FIG. 2 to FIG. 9, FIG. 11, and FIG. 14, specifically, a first connection structure is disposed on the housing 1, and a second connection structure is disposed on the bottom cover 2. In the locked state, the housing 1 and the bottom cover 2 are connected through the first connection structure and the second connection structure to form locking. In the unlocked state, the first connection structure and the second connection structure that are between the housing 1 and the bottom cover 2 are separated or disconnected.

[0027] The first connection structure includes a first clamping portion 17, the second connection structure includes a second clamping portion 23, and the second clamping portion 23 is disposed in the transverse direction. In the locked state, the first clamping portion 17 is clamped to the second clamping portion 23. In the unlocked state, because the bottom cover 2 is driven by the user to move relative to the housing 1 in the transverse direction, the clamping between the first clamping portion 17 and the second clamping portion 23 is released.

[0028] It should be noted that either of the first clamping portion 17 and the second clamping portion 23 is a fastener, and the other is a slot clamped to the fastener. As shown in FIG. 2 to FIG. 9, FIG. 11, and FIG. 14, in some embodiments, the first clamping portion 17 is a fastener, and the second clamping portion 23 is a slot.

[0029] As shown in FIG. 9 and FIG. 14, in some embodiments, the first connection structure further includes a third clamping portion 18, the second connection structure further includes fourth clamping portions 24, the fourth clamping portions 24 are disposed on two sides perpendicular to a movement direction and the longitudinal direction of the bottom cover 2, and the third clamping portion 18 is clamped to the fourth clamping portion 24.

[0030] The third clamping portion 18 and the fourth clamping portions 24 are disposed, and the fourth clamping portions 24 are symmetrically disposed on two sides perpendicular to the movement direction and the longitudinal direction of the bottom cover 2, so that connection strength between the housing 1 and the bottom cover 2 can be strengthened, and separation between the housing 1 and the bottom cover 2 caused by a false touch of the user can be avoided.

[0031] As shown in FIG. 9, in some embodiments, a buffer portion 25 is disposed extending from the fourth clamping portion 24 of the bottom cover 2. A groove opening 26 is provided on the buffer portion 25. When the housing 1 is assembled with the bottom cover 2, the third clamping portion 18 enters the buffer portion 25 through the groove opening 26, and moves from the buffer portion 25 to the fourth clamping portion 24 to complete clamping. When the housing 1 is detached from the bottom cover 2, the third clamping portion 18 moves to the buffer portion 25, and is separated from the groove opening 26.

[0032] The buffer portion 25 extends from the fourth clamping portion 24 of the bottom cover 2 in the transverse direction, and a shape size of the groove opening 26 is greater than or equal to that of the third clamping portion 18, so that the third clamping portion 18 can smoothly enter or leave the buffer portion 25 through the groove opening 26. When the bottom cover 2 is detached from the housing 1, the bottom cover 2 moves in the transverse direction, and the third clamping portion 18 is also separated from the fourth clamping portion 24 to the buffer portion 25. Then, the bottom cover 2 is separated from the housing 1 in the longitudinal direction, so that the third clamping portion 18 can be separated from the groove opening 26. During mounting of the bottom cover 2 and the housing 1, after the third clamping portion 18 of the housing 1 is aligned with the groove opening 26, the bottom cover 2 is pressed into the housing 1, so that the third clamping portion 18 enters the buffer portion 25 through the groove opening 26, and then the bottom cover 2 is pushed to move in the transverse direction, so that the third clamping portion 18 is clamped to the fourth clamping portion 24. Therefore, a connection between the bottom cover 2 and the housing 1 can be further strengthened through disposition of the buffer portion 25 and the groove opening 26.

[0033] As shown in FIG. 14, in some embodiments, an end face that is of the third clamping portion 18 and that faces the first clamping portion 17 is disposed as a vertical face perpendicular to an inner wall of the housing 1, and an end face that is of the third clamping portion 18 and that faces away from the first clamping portion 17 is disposed as an inclined face inclined to the inner wall of the housing 1. A clamping surface of the fourth clamping portion 24 is adapted to a clamping surface of the third clamping portion 18.

[0034] The second clamping portion 23 of the bottom cover 2 is disposed in a direction in which a track chute 22 extends to a second portion 222. Therefore, to prevent the bottom cover 2 from easily moving in a direction in which the second portion 222 points to a first portion 221, resulting in separation of the bottom cover 2 from the housing 1, the end surface that is of the third clamping portion 18 and that faces the first clamping portion 17 is disposed as the vertical surface perpendicular to the inner wall of the housing 1, and the clamping surface of the fourth clamping portion 24 is adapted to the clamping surface of the third clamping portion 18, thereby strengthening strength of the third clamping portion 18 and the fourth clamping portion 24 in the direction in which the second portion 222 points to the first portion 221. In addition, to facilitate mounting of the bottom cover 2 and the housing 1, the end surface that is of the third clamping portion 18 and that faces away from the first clamping portion 17 is disposed as the inclined surface inclined to the inner wall of the housing 1, so that it is easier for the bottom cover 2 to move in a direction in which the first portion 221 points to the second portion 222.

[0035] It should be noted that, to avoid excessively great difficulty when the user separates the bottom cover 2 from the housing 1, a chamfer is disposed on the vertical plane, thereby reducing the difficulty of the user and a force used during the separation. In addition, to better mount the bottom cover 2 and the housing 1, a chamfer is also disposed on the inclined surface.

[0036] It may be understood that the first connection structure and the second connection structure may further include a plurality of clamping portions.

[0037] Further, in the unlocked state, the bottom cover 2 can be detached from the housing 1 in the longitudinal direction. The first connection structure and the second connection structure between the bottom cover 2 and the housing 1 are disconnected, so that the user can separate the bottom cover 2 from the housing 1 in the longitudinal direction, thereby completing detachment of the bottom cover 2 from the housing 1.

[0038] Specifically, the aerosol generating device further includes: a movable blocking component 32, capable of selectively moving between a blocking position and an avoidance position. The blocking component 32 moves to the blocking position, and is configured to prevent the bottom cover 2 from moving in the transverse direction, to avoid conversion from the locked state to the unlocked state. The blocking component 32 moves to the avoidance position, and is configured to allow the bottom cover 2 to move in the transverse direction, to implement conversion from the locked state into the unlocked state. The blocking component 32 is, for example, a countersunk-head screw, and is fixedly connected to an operation element 31, to be operated by the operation element 31 for movement.

[0039] Further, the blocking component 32 is disposed on the bottom cover 2. A partition wall 14 is disposed in the housing 1. At the blocking position, at least a part of the blocking component 32 is abutted against the partition wall 14; and / or at the avoidance position, the blocking component 32 is separated from or longitudinally staggered with the partition wall 14.

[0040] Further, as shown in FIG. 2 to FIG. 8, and FIG. 14, in some embodiments, a blocking portion 11 is disposed extending from the partition wall 14. At the blocking position, at least a part of the blocking component 32 is abutted against the blocking portion 11. Alternatively, at the avoidance position, the blocking component 32 is separated from or longitudinally staggered with the blocking portion 11.

[0041] When the blocking component 32 is located at the blocking position, the blocking component 32 is abutted against the blocking portion 11, and the second clamping portion 23 of the bottom cover 2 is disposed in the transverse direction. Therefore, the blocking component 32 is abutted against the blocking portion 11, and the first clamping portion 17 is clamped to the second clamping portion 23, so that the housing 1 is fixedly connected to the bottom cover 2. When the blocking component 32 is located at the avoidance position, because the blocking component 32 is separated from the blocking component 11, the user may push the bottom cover 2 to move in the transverse direction, to separate the first clamping portion 17 from the second clamping portion 23, so that a fixed connection between the housing 1 and the bottom cover 2 is broken, and the housing 1 is separated from the bottom cover 2.

[0042] Further, as shown in FIG. 9 and FIG. 11, in some embodiments, a track chute 22 may be provided on the bottom cover 2, a first portion is disposed at one end of the track chute 22, a second portion 222 is disposed at the other end of the track chute 22, a third portion 223 is disposed on the track chute 22, the third portion 223 is configured to connect the first portion 221 and the second portion 222, and a width of the first portion 221 and a width of the second portion 222 are greater than that of the third portion 223.

[0043] The first portion 221 is disposed at the blocking position, and the second portion 222 is disposed at the avoidance position. The blocking component 32 can selectively move between the first portion 221 and the second portion 222, so that conversion between the locked state and the unlocked state can be implemented.

[0044] The blocking component 32 moves to the first portion 221. The width of the third portion 223 is set to be less than the width of the first portion 221, and the blocking component 32 is at least partially abutted against the blocking portion 11. Therefore, the bottom cover 2 is prevented from moving in the transverse direction, to avoid conversion from the locked state to the unlocked state.

[0045] The blocking component 32 moves to the second portion 222. The blocking component 32 is separated from the blocking component 11, and the width of the third portion 223 is set to be less than the width of the second portion 222. Therefore, the bottom cover 2 is allowed to move in the transverse direction, to implement conversion from the locked state to the unlocked state.

[0046] Further, as shown in FIG. 2 to FIG. 7, at the blocking position, at least a part of the blocking component 32 coincides with the partition wall 14 in the longitudinal direction of the housing 1; and at the avoidance position, is staggered with the partition wall 14 in the longitudinal direction of the housing 1.

[0047] To ensure that when the blocking component 32 is located at the blocking position, the bottom cover 2 can be prevented from moving in the transverse direction, to avoid conversion from the locked state to the unlocked state, only when at least a part of the blocking component 32 coincides with the blocking portion 11 extending from the partition wall 14 in the longitudinal direction of the housing 1 at the blocking position, the blocking component 32 can be abutted against the partition wall 14, to restrict movement of the bottom cover 2. In addition, to ensure that during movement of the blocking component 32 to the avoidance position, the bottom cover 2 can be allowed to move in the transverse direction, to implement conversion from the locked state into the unlocked state, when the blocking component 32 is located at the avoidance position, the blocking component 32 is staggered with the partition wall 14 in the longitudinal direction of the housing 1, so that during movement of the bottom cover 2, the blocking component 32 is not abutted against the blocking portion 11 extending from the partition wall 14, thereby smoothly releasing a connection between the first connection structure and the second connection structure.

[0048] Further, the blocking component 32 is closer to the near end at the blocking position than at the avoidance position.

[0049] As shown in FIG. 2 to FIG. 7, when a track chute 22 may be provided on the bottom cover 2, it may be set that a chute depth of the first portion 221 is less than a chute depth of the second portion 222.

[0050] Specifically, the housing 1 further has a first side 19 and a second side 10 that face away from each other in the transverse direction.

[0051] The partition wall 14 separates a space in the housing 1 into a first space 15 and a second space 16 that are isolated from each other in the transverse direction, the first space 15 is close to the first side 19, and the second space 16 is close to the second side 10.

[0052] The battery cell 4 is accommodated and assembled in the first space 15, and the heating element and the aerosol generating substrate are accommodated in the second space 16.

[0053] Specifically, as shown in FIG. 14, and FIG. 2 to FIG. 8, in some embodiments, a partition wall 14 is disposed on the housing 1, and the partition wall 14 divides the inside of the housing 1 into a first space 15 and a second space 16.

[0054] As shown in FIG. 2, a power supply assembly is disposed in the first space 15 of the aerosol generating device. The power supply assembly includes a battery cell 4 and a control circuit board. The battery cell 4 provides power for operating the aerosol generating device. The battery cell 4 may be a rechargeable battery cell 4 or a disposable battery cell 4.

[0055] The control circuit board may control an overall operation of the aerosol generating device. The control circuit board not only controls operations of the battery cell 4 and an atomization assembly 51, but also controls operations of other elements in the aerosol generating device.

[0056] The aerosol generating substrate is a liquid aerosol generating substrate or a fixed aerosol generating substrate. That is, the liquid aerosol generating substrate may be a liquid substrate, and the fixed liquid aerosol generating substrate may be a solid substrate.

[0057] When the aerosol generating substrate is a liquid aerosol generating substrate, an atomization component 51, a fixed sealing seat 52, and a tube element 53 are disposed in the second space 16 of the aerosol generating device. The atomization component 51 is electrically connected to the power supply component. The fixed sealing seat 52 and an inner wall of the housing 1 define a liquid storage cavity used for storing an aerosol generating substrate. The atomization component 51 and the tube element 53 are mounted to the fixed sealing seat 52, and the tube element 53 is disposed around the atomization component 51. The tube element 53 is configured to transfer a liquid substrate in the liquid storage cavity to the atomization component 51. Under an effect of power provided by the power supply component, the atomization component 51 atomizes the liquid substrate to form a smokable aerosol.

[0058] The atomization assembly 51 includes a heating element, to heat the liquid aerosol generating substrate, to form a smokable aerosol. The heating element may be a resistive heating element. In another example, the atomization assembly 51 includes an ultrasonic atomization sheet, which generates high-frequency vibration to ultrasonically atomize a liquid aerosol generating substrate to form a smokable aerosol.

[0059] The atomization assembly 51 further includes a liquid guiding element. The liquid guiding element may be, for example, a cotton fiber, a metal fiber, a ceramic fiber, a glass fiber, or a porous ceramic. By means of a capillary action, the liquid aerosol generating substrate stored in the liquid storage cavity may be transferred to the heating element or the ultrasonic atomization sheet.

[0060] For the tube element, a plurality of liquid guiding holes are provided on the tube element 53, and the plurality of liquid guiding holes may be peripherally provided at intervals, so that the liquid substrate in the liquid storage cavity evenly enters the liquid guiding element through the plurality of liquid guiding holes, and the heating element can sufficiently and evenly heat the liquid substrate. Preferably, the tube element 53 is made of a relatively thin rigid material, such as a ceramic or stainless steel.

[0061] Further, as shown in FIG. 2, a nozzle 12 and a gas tube 13 extending inward through the nozzle 12 are provided at the near end of the housing 1. The aerosol reaches the nozzle 12 through the gas tube 13. The user may smoke the aerosol through the nozzle 12. An opening is provided at the far end of the housing 1, and the bottom cover 2 covers the opening.

[0062] It should be noted that, as shown in FIG. 2, the housing 1 may be integrally manufactured. The housing 1 may further be divided into a housing body and a top cover. The housing body is connected to the top cover, and the nozzle 12 and the air tube 13 are disposed on the top cover.

[0063] An air flow channel extends from an air inlet 21 to the nozzle 12. Air flows into the air flow channel through the air inlet 21, flows through the atomization assembly 51, and then flows from the nozzle 12 into the mouth of the user.

[0064] In a preferable implementation, the atomization assembly 51 defines some air flow channels. For example, an inner hollow part of a tube-shaped atomization component 51 defines some air flow channels. A surface of a plate-shaped atomization component 51 defines some air flow channels.

[0065] As shown in FIG. 2, in some embodiments, an air flow detector 6 is further disposed on the aerosol generating device for sensing an air pressure change in the air flow channel to output an electrical signal, that is, detect whether an electronic atomization device is smoked. The air flow detector 6 may be disposed in the air flow channel, or be in flow communication with the air flow channel. The air flow detector 6 is electrically connected to the battery cell 4.

[0066] As shown in FIG. 2, in a preferred embodiment, a sealing silicon member 7 is further disposed on the aerosol generating device. The sealing silicon member 7 seals an opening of the second space 16. An air guiding channel 71 is provided on the sealing silicon member 7. An opening at one end of the air guiding channel 71 communicates with the air inlet 21, and an opening at the other end of the air guiding channel 71 communicates with the second space 16. The air flow detector 6 is disposed in the sealing silicon member 7. The air flow detector 6 preferably uses a barometric pressure sensor.

[0067] When the aerosol generating substrate is a solid aerosol generating substrate, a heating cavity of the aerosol generating device and the heating element disposed in the heat cavity, and a cavity opening is provided on the heating cavity.

[0068] A cavity extending in a longitudinal direction is provided in the second space 16 of the aerosol generating device. The cavity is used for accommodating a cigarette-like solid aerosol generating substrate used in combination with the aerosol generating device. The heating element is attached to an external wall of the cavity, to heat the solid aerosol generating substrate in the cavity. When heated, some active substances filled in the solid aerosol generating substrate volatilize to generate an aerosol. The user may smoke on the solid aerosol generating substrate to inhale the aerosol. In some optional embodiments, the heating element at least partially extends into the cavity, and an end portion that is of the heating element and that extends into the cavity is configured as a pin shape or a sheet shape, so that the heating element is smoothly inserted into an aerosol generating product to be heated.

[0069] Further, as shown in FIG. 7, the bottom cover 2 is disposed to be capable of moving from the first side 19 to the second side 10 in the transverse direction, to convert from the locked state to the unlocked state; and in the unlocked state, at least a part of the bottom cover 2 protrudes on the second side 10. The part that is of the bottom cover 2 and that protrudes out of the second side 10 may help the user to detach the bottom cover 2 from the housing 1.

[0070] Further, as shown in FIG. 2 to FIG. 8, the aerosol generating device further includes: an operation element 31, disposed to be operated by the user to drive a blocking component 32 to move between a blocking position and an avoidance position. The bottom cover 2 further has an air inlet 21, configured to allow external air to enter the aerosol generating device. The operation element 31 can further be operated by the user to open and close the air inlet 21.

[0071] The user operates the operation element 31, so that not only the blocking component 32 can be driven to move between the blocking position and the avoidance position, to implement conversion from the locked state to the unlocked state, but also the air inlet 21 can be open and closed, to prevent a juvenile from smoking the aerosol by mistake. Therefore, the user can implement a child lock function and a detachment function only by controlling the operation element 31.

[0072] In some embodiments, as shown in FIG. 2 to FIG. 8, the aerosol generating device may further include: a movable sealing member 33, disposed to move between a closed position and an open position, and operated by a user to drive the blocking component 32 to move between the closed position and the open position, to selectively close the air inlet at the closed position and open the air inlet at the open position.

[0073] In some embodiments, a width of the third portion 223 is set to be less than a width of the first portion 221 and a width of the second portion 222. When the user does not press the operation element 31 to compress and deform the sealing member 33, the blocking component 32 cannot be separated from the first portion 221 or the second portion 222, and cannot move in the third portion 223. Because the third portion 223 is configured to connect the first portion 221 and the second portion 222, the blocking component 32 cannot move from the first portion 221 to the second portion 222, or move from the second portion 222 to the first portion 221, thereby avoiding a misoperation of the user. If the user intends to open or close the air inlet 21 or replace the battery cell 4, the user needs to press the operation element 31.

[0074] As shown in FIG. 2 to FIG. 4, when a user does not use the aerosol generating device and needs to prevent a juvenile from smoking the aerosol by mistake, the blocking component 32 is located at the first portion 221, and the sealing member 33 seals the air inlet 21. Because the air inlet 21 is sealed, and air cannot be smoked from the outside by using the aerosol generating device, the juvenile cannot smoke the aerosol. Meanwhile, when the blocking component 32 is located at the first portion 221, the blocking component 32 is abutted against the blocking portion 11. By means of cooperation between the blocking component 32 and the blocking portion 11, movement of the bottom cover 2 in a direction in which the second portion 222 points to the first portion 221 is restricted, so that the housing 1 cannot be detached from the bottom cover 2.

[0075] As shown in FIG. 5 to FIG. 8, when needing to smoke the aerosol by using the aerosol generating device, a user may press the operation element 31 to compress and deform the sealing member 33, so that the blocking component 32 is separated from the first portion 221 of the track chute 22. In this case, when the user pushes the operation element 31, the blocking component 32 can move from the first portion 221 to the second portion 222 of the track chute 22. Because the sealing member 33 and the blocking component 32 are both mounted on the operation element 31, the sealing member 33 opens the air inlet 21. After the blocking component 32 moves to the second portion 222, the user loosens the operation element 31, and the sealing member 33 recovers, so that the blocking component 32 is accommodated into the second portion 222 of the track chute 22. Because the blocking component 32 moves to the second portion 222, the blocking component 32 is not abutted against the blocking portion 11. If needing to replace the battery cell 4, the user may push the bottom cover 2 to move in the direction in which the second portion 222 points to the first portion 221, to destroy a connection relationship between the bottom cover 2 and the housing 1, so that the bottom cover 2 is separated from the housing 1, and the battery cell 4 accommodated inside the housing 1 is replaced with. After the replacement is completed, the bottom cover 2 is pushed to move in a direction in which the first portion 221 points to the second portion 222, so that the bottom cover 2 is reconnected to the housing 1, thereby completing assembly and detachment of the bottom cover 2 and the housing 1.

[0076] As shown in FIG. 4 to FIG. 8, the operation element 31 is in a locked state in FIG. 4. Specifically, the blocking component 32 is limited in the first portion 221 of the track chute 22, and a size of the blocking component 32 is greater than a width of the third portion 223 of the track chute 22. In this case, the blocking component 32 cannot move from the third portion 223 to the second portion 222. In this case, the user cannot directly drive the operation element 31 to move from a position shown in FIG. 4 to a position shown in FIG. 6, and the operation element 31 is locked.

[0077] Further, before the movement, the operation element 31 needs to be unlocked. Specifically, the user presses the operation element 31 to cause the blocking component 32 to disengage inward from the first portion 221 of the track chute 22. For example, as shown in FIG. 5, in this case, the blocking component 32 can move through the third portion 223 to the second portion 222.

[0078] In some embodiments, the operation element 31 is pressed by the user, and then moves toward a near end in a longitudinal direction, to implement conversion from locking to unlocking. In some embodiments, the operation element 31 can be operated by the user to move in the longitudinal direction of the housing 1, to implement conversion from locking to unlocking.

[0079] Moreover, as shown in FIG. 4, FIG. 5, and FIG. 11, a depth of the first portion 221 of the track chute 22 is less than a depth of the second portion 222, so that when being accommodated in the first portion 221, the blocking component 32 is more convex than the blocking component 32 accommodated in the second portion 222. Alternatively, when being accommodated in the first portion 221, the blocking component 32 is closer to the near end than the blocking component 32 accommodated in the second portion 222. Moreover, as shown in FIG. 4, when the blocking component 32 is accommodated in the first portion 221, a convex portion that protrudes out of or is exposed out of the first portion 221 is abutted against the blocking portion 11 of the partition wall 14 to form blocking, to prevent movement of the bottom cover 2 relative to the housing 1. However, when the blocking component 32 is accommodated in the second portion 222, the blocking component 32 is staggered with the blocking portion 11 of the partition wall 14 in the longitudinal direction of the housing 1, thereby allowing the bottom cover 2 to move relative to the housing 1.

[0080] As shown in FIG. 2 to FIG. 4, when the user does not need to smoke the aerosol by using the aerosol generating device, the user may press the operation element 31 to compress and deform the sealing member 33, so that the blocking component 32 is separated from the second portion 222 of the track chute 22. Further, when pushing the operation element 31, the user can move the blocking component 32 from the second portion 222 to the first portion 221 of the track chute 22, so that the sealing member 33 seals the air inlet 21.

[0081] As shown in FIG. 2 to FIG. 10, FIG. 12, and FIG. 13, in some embodiments, the blocking component 32 includes a movement portion 321 and a connection portion 322, the movement portion 321 is connected to the connection portion 322, and the movement portion 321 is accommodated in the first portion 221 or the second portion 222. The operation element 31 includes a pressing portion 311 and a mounting portion 312, the pressing portion 311 is connected to the mounting portion 312, and a connection portion 322 is embedded in the mounting portion 312. The sealing member 33 includes a base 331, at least three deformation portions 332, and at least three sealing portions 333. The deformation portions 332 are sequentially arranged to be connected to the base 331, the deformation portions 332 are connected to the sealing portions 333 in a one-to-one correspondence, the base 331 is abutted against the pressing portion 311. A mounting hole 334 is provided on the sealing portion 333 located in the middle, and the operation element 31 fixes the sealing member 33 through the mounting hole 334 by using the mounting portion 312.

[0082] When the blocking component 32 is located at the second portion 222, the sealing portions 333 are all abutted against the bottom cover 2. When the blocking component 32 is located at the first portion 221, one of the sealing portions 333 seals the air inlet 21, and the other sealing portions 333 are both abutted against the bottom cover 2.

[0083] Specifically, the movement portion 321 and the connection portion 322 are perpendicular to each other. The movement portion 321 is accommodated in the first portion 221 or the second portion 222. The connection portion 322 passes through the track chute 22 to be connected to the mounting portion 312. When the user presses the pressing portion 311, the deformation portion 332 undergoes compression deformation, so that the operation element 31 drives the blocking component 32 to extend inward into the housing 1. Therefore, the movement portion 321 is separated from the first portion 221 or the second portion 222. When the pressing portion 311 is pushed, the connection portion 322 moves in the track chute 22.

[0084] It should be noted that, the blocking component 32 may be a screw. The mounting portion 312 is a protrusion disposed at the pressing portion 311, and a screw hole groove is provided at the protrusion. The screw and the screw hole groove are in a threaded connection. In addition, the sealing portion 333 located in the middle is sleeved on the protrusion through the mounting hole 334, so that the sealing member 33 is fixed to the operation element 31.

[0085] Further, a groove 313 is further provided on an edge of the operation element 31, and the sealing member 33 is accommodated in the groove 313, thereby strengthening fixing of the sealing member 33.

[0086] Further, at least one stripe protrusion 314 may further be disposed on a side facing away from the groove 313 of the operation element 31. The stripe protrusion 314 can increase friction between a finger of the user and the pressing portion 311, so that the user can better push the operation element 31.

[0087] Further, the first portion 221 and the second portion 222 are groove holes provided at two ends of the track chute 22, and a shape size of the groove hole is the same as a shape size of the movement portion 321. For example, in this embodiment, the movement portion 321 is circular. In this case, the first portion 221 and the second portion 222 are circular, and a diameter of the movement portion 321 is the same as that of the first portion 221 and that of the second portion 222. It may be understood that the movement portion 321 may alternatively have another shape, provided that the shape size of the movement portion 321 keeps consistent with a shape size of the first portion 221 and a shape size of the second portion 222.

[0088] A width of the first portion 221 and a width of the second portion 222 are greater than a width of the third portion 223. Therefore, when the movement portion 321 is located at the first portion 221 or the second portion 222 and the user does not press the pressing portion 311, the movement portion 321 is accommodated in the first portion 221 or the second portion 222, and cannot move in the track chute 22.

[0089] Specifically, because a mounting hole 334 needs to be provided at a sealing portion 333 to be fixedly connected to the operation element 31, and a sealing portion 333 is further needed to seal the air inlet 21, in addition, to ensure balance of reaction forces of the deformation portion 332 received everywhere of the pressing portion 311 when the pressing portion 311 is pressed, a deformation portion 332 is further disposed to balance the reaction forces of the deformation portion 332 received everywhere of the pressing portion 311, thereby improving user experience, and enabling the user to better push the operation element 31. Therefore, at least three deformation portions 332 and at least three sealing portions 333 need to be disposed. Preferably, in this embodiment, three deformation portions 332 and three sealing portions 333 are disposed. In another embodiment, five deformation portions 332 and five sealing portions 333, seven deformation portions 332 and seven sealing portions 333, or the like may alternatively be disposed.

[0090] Further, to avoid a false touch on the operation element 31, an accommodating groove 27 is disposed on an outer side of the bottom cover 2. The operation element 31 is accommodated in the accommodating groove 27, so that the operation element 31 can be lower than a level surface of a bottom surface of the bottom cover 2.

[0091] As shown in FIG. 4, FIG. 6, and FIG. 11, in some embodiments, a thickness of the movement portion 321 is greater than a groove depth of the first portion 221, and the thickness of the movement portion 321 is less than or equal to a groove depth of the second portion 222.

[0092] The thickness of the movement portion 321 is greater than the groove depth of the first portion 221. Therefore, a part of the movement portion 321 extends beyond the first portion 221, and the part of the movement portion 321 is abutted against the blocking portion 11 when the blocking component 32 is located at the first portion 221, that is, a part of a locking portion is accommodated at the first portion 221. When another part of the locking portion is limited by the blocking portion 11, movement of the bottom cover 2 in a direction in which the second portion 222 points to the first portion 221 is limited, so that a connection relationship between the bottom cover 2 and the housing 1 cannot be broken.

[0093] However, the thickness of the movement portion 321 is less than or equal to the groove depth of the second portion 222. Therefore, when the movement portion 321 is located at the second portion 222, the movement portion 321 is completely accommodated at the second portion 222. Because there is no part that is of the second portion 222 and that is beyond the second portion 222, the part is not abutted against the blocking component 11. Therefore, the bottom cover 2 can move in a direction in which the first portion 221 points to the second portion 222, thereby breaking a connection relationship between the bottom cover 2 and the housing 1, and smoothly completing detachment of the bottom cover 2 from the housing 1.

[0094] As shown in FIG. 4, FIG. 5, FIG. 6, and FIG. 11, in some embodiments, a compression deformation amount of the sealing member 33 is greater than the groove depth of the first portion 221 and the groove depth of the second portion 222.

[0095] To ensure that after the user presses the pressing portion 311, the movement portion 321 of the blocking component 32 can be separated from the first portion 221 or the second portion 222, it needs to be ensured that the compression deformation amount of the sealing member 33 is greater than the groove depth of the first portion 221 and the groove depth of the second portion 222, so that after the user presses the pressing portion 311, the sealing member 33 undergoes compression deformation, and an amount of extension of the blocking component 32 into the housing 1 is greater than the groove depth of the first portion 221 and the groove depth of the second portion 222. In this case, the movement portion 321 can be separated from the first portion 221 or the second portion 222, thereby ensuring that when the user subsequently pushes the pressing portion 311, the blocking component 32 can move between the first portion 221 and the second portion 222 of the track chute 22.

[0096] As shown in FIG. 4 and FIG. 6, an embodiment of this application further provides an aerosol generating device, including: a longitudinal direction and a transverse direction perpendicular to the longitudinal direction; a liquid storage cavity, configured to store a liquid aerosol generating substrate; a heating element, configured to heat the liquid aerosol generating substrate to generate an aerosol; an air inlet 21, configured to allow air to enter the aerosol generating device; a movable sealing member 33, disposed to move between a closed position and an open position, to selectively close the air inlet 21 at the closed position and open the air inlet 21 at the open position; and an operation element 31, disposed to be operated by a user to move in the transverse direction, to drive the sealing member 33 to move between the closed position and the open position; where the operation element 31 has a locked state and an unlocked state, is in the locked state to prevent the user from operating the operation element 31 to move in the horizontal direction, and is in the unlocked state to allow the user to operate the operation element 31 to move in the horizontal direction; and the sealing member 33 is elastic, and is disposed to provide an elastic force when the sealing member 33 is located at the closed position and / or the open position, to drive the operation element 31 to convert from the unlocked state to the locked state; or the sealing member 33 is disposed to provide an elastic force to the operation element 31, to keep the operation element in the locked state.

[0097] Further, the operation element 31 can be pressed by the user, to convert from the locked state to the unlocked state.

[0098] In some embodiments, a width of a third portion 223 is set to be less than a width of a first portion 221 and a width of a second portion 222. The third portion 223 is configured to connect the first portion 221 and the second portion 222, and when a user does not press the operation element 31 to compress and deform the sealing member 33, the blocking component 32 cannot be separated from the first portion 221 or the second portion 222, and cannot move in the third portion 223. Therefore, the user is prevented from operating the operation element 31 to move in the transverse direction. Therefore, the operation element 31 is in a locked state, and a misoperation of the user can be avoided. When intending to open or close the air inlet 21, the user needs to press the operation element 31, so that the blocking component 32 is separated from the first portion 221 or the second portion 222, and may move in the third portion 223. The user is allowed to operate the operation element 31 to move in the transverse direction, so that the operation element 31 is in the unlocked state.

[0099] The foregoing descriptions are merely preferred embodiments of this application, and are not intended to limit the technical scope of this application. Therefore, any slight alteration, equivalent change or modification made to the above embodiments according to the technical essence of this application shall fall within the scope of the technical solutions of this application.
