Liquid storage structure and aerosol-generating device

Abstract

The application is suitable for the field of atomization technology, and provides a liquid storage structure and an aerosol generating device. The liquid storage structure comprises a shell assembly, a sealing structure and a cover. The shell assembly is internally provided with a liquid storage cavity. The sealing structure is an elastic structure, is arranged on the shell assembly, and covers the liquid storage cavity. The sealing structure is provided with a liquid inlet groove, which comprises a liquid inlet hole and a plurality of linear grooves arranged at intervals. Each linear groove extends to the inner circumferential wall of the liquid inlet hole, and the liquid inlet hole and the linear grooves are both communicated with the liquid storage cavity. The cover is movably connected to the shell assembly and can reciprocate relative to the shell assembly to open or close the liquid inlet groove. The sealing structure elastically abuts between the shell assembly and the cover. In this way, the aperture of the liquid inlet groove is relatively small. When the cover is mistakenly touched to open the liquid inlet groove, the aerosol generating substrate in the liquid storage cavity is not easy to overflow through the liquid inlet groove, thereby reducing the risk of leakage of the aerosol generating substrate in the liquid storage cavity.

Description

Technical Field

[0001] This application belongs to the field of atomization technology, and more specifically, relates to a liquid storage structure and an aerosol generating device. Background Technology

[0002] An aerosol generating device is a device used to heat an aerosol generating matrix, causing the matrix to atomize and form an aerosol. The aerosol formed from this atomized matrix can then be inhaled by a user.

[0003] Aerosol generating devices typically include a reservoir for storing the aerosol generating matrix, and a nozzle structure for covering the reservoir. By pushing the nozzle structure, the user can open the reservoir, allowing them to add the aerosol generating matrix into it.

[0004] However, when the aerosol generating device is placed in a pocket or similar object, the nozzle structure can be accidentally activated, opening the liquid storage chamber and causing the aerosol generating matrix inside the liquid storage chamber to leak outside the aerosol generating device.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0012] In some embodiments, one of the housing assembly and the cover is provided with a first groove, and the other is provided with a guide structure; the guide structure is inserted into the first groove in a first direction and is used to slide along the first groove in a second direction.

[0013] In some embodiments, the first groove is provided with a first groove wall and a second groove wall on opposite sides along the second direction, and the guide structure is limited to the space between the first groove wall and the second groove wall along the second direction.

[0014] In some embodiments, the guide structure includes a fixing part and a first guide part disposed on the fixing part. The fixing part is fixed to the housing assembly or cover, and the first guide part is inserted into the first slide groove along a first direction. In a third direction, the size of the fixing part is larger than the size of the first guide part, the size of the fixing part is larger than the size of the first slide groove, and the size of the first slide groove is larger than the size of the first guide part. Among them, the third direction is perpendicular to the first direction and the second direction, respectively.

[0015] In some embodiments, a first groove is provided on the side of the cover member facing the housing assembly along a first direction, the housing assembly is provided with a mounting hole on the side of the cover member along the first direction, a fixing part is fixed in the mounting hole, and at least a portion of the first guide part is located outside the mounting hole.

[0016] In some embodiments, the guide structure is an elastic structure.

[0017] In some embodiments, the guide structure is a spring pin.

[0018] In some embodiments, the housing assembly has a mounting groove at one end along a first direction, the liquid storage chamber is exposed in the mounting groove, and at least a portion of the sealing structure is disposed in the mounting groove. The mounting groove has a second sliding groove on at least one side along the third direction, and the cover has a second guide portion on at least one side along the third direction.

[0021] The beneficial effects of the liquid storage structure and aerosol generating device provided in this application are as follows: The liquid storage structure provided in this application embodiment features an elastic sealing structure, with each linear groove extending to the inner circumferential wall of the inlet hole. This allows the sealing structure to deform at the linear grooves, thereby enlarging the inlet hole. This design allows for a smaller inlet hole diameter before deformation at the linear groove, and the linear grooves themselves are linear, resulting in a smaller width. Consequently, the smaller inlet groove diameter prevents the aerosol-generating matrix within the storage chamber from overflowing if the cover is accidentally opened, thus reducing the risk of leakage.

[0022] Furthermore, the sealing structure elastically abuts against the housing assembly and the cover, so that the friction between the sealing structure and the cover provides a certain resistance to the opening of the liquid inlet groove by the cover. This can reduce the risk of the cover being accidentally touched and opening the liquid inlet groove, thereby reducing the risk of aerosol generation matrix leakage in the liquid storage cavity after the cover is opened.

[0023] The aerosol generating apparatus provided in this application reduces the risk of leakage of the aerosol generating matrix in the storage chamber by adopting the liquid storage structure involved in the above embodiments.

This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0036] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments: Please refer to the following: Figures 1 to 4,in, Figure 1 This is a perspective view of the aerosol generating apparatus provided in some embodiments of this application when the liquid inlet tank 201 is closed. Figure 2 This is a perspective structural view of the housing assembly 10 of the aerosol generating apparatus provided in some embodiments of this application. Figure 3 This is a partial perspective structural diagram of an aerosol generating apparatus provided in some embodiments of this application. Figure 4 This is a perspective view of the aerosol generating device provided in some embodiments of this application when the liquid inlet trough 201 is open. The liquid storage structure provided in this application includes a housing assembly 10, a sealing structure 20, and a cover member 30. The housing assembly 10 has a liquid storage chamber 101. The sealing structure 20 is an elastic structure, disposed on the housing assembly 10, and covers the liquid storage chamber 101. The sealing structure 20 has a liquid inlet trough 201, which includes an inlet hole 2011 and a plurality of spaced linear grooves 2012. Each linear groove 2012 extends to the inner peripheral wall of the inlet hole 2011, and both the inlet hole 2011 and the linear grooves 2012 communicate with the liquid storage chamber 101. The cover member 30 is movably connected to the housing assembly 10 and can reciprocate relative to the housing assembly 10 to open or close the liquid inlet trough 201. The sealing structure 20 elastically abuts against the housing assembly 10 and the cover member 30.

[0037] The housing assembly 10 is the outer shell structure of the liquid storage structure. The liquid storage chamber 101 is a cavity formed inside the housing assembly 10, wherein the liquid storage chamber 101 may be used, but is not limited to, to store the aerosol generation matrix.

[0038] The sealing structure 20 refers to a structure used at least to seal the liquid storage chamber 101. Specifically, the sealing structure 20 has both sealing and elastic properties. The sealing structure 20 can be a rubber gasket, silicone gasket, etc.

[0039] The sealing structure 20 is disposed on the housing assembly 10 and covers the liquid storage cavity 101, so that the sealing structure 20 can achieve a sealing effect on the liquid storage cavity 101.

[0040] Specifically, in the direction in which the sealing structure 20 covers the liquid storage cavity 101, the liquid inlet groove 201 penetrates the sealing structure 20, so that the liquid inlet groove 201 and the liquid storage cavity 101 are connected.

[0041] Understandably, the cover 30 is movably connected to one end of the housing assembly 10 having the sealing structure 20.

[0042] The cover 30 is capable of reciprocating relative to the housing assembly 10 to open or close the liquid inlet 201. This means that when the cover 30 moves relative to the housing assembly 10, it can move such that at least a portion of the cover 30 does not cover the side of the liquid inlet 201 away from the liquid storage chamber 101, thus opening the liquid inlet 201; or it can move such that the cover 30 covers the side of the liquid inlet 201 away from the liquid storage chamber 101, thus closing the liquid inlet 201. When the cover 30 opens the liquid inlet 201, the user can replenish the aerosol generation matrix into the liquid storage chamber 101 through the liquid inlet 201. When the cover 30 closes the liquid inlet 201, it provides protection for both the liquid inlet 201 and the liquid storage chamber 101.

[0043] The sealing structure 20 elastically abuts against the housing assembly 10 and the cover 30, which means that the sealing structure 20 is located between the housing assembly 10 and the cover 30, and the two sides of the sealing structure 20 elastically abut against the housing assembly 10 and the cover 30 respectively.

[0044] The liquid storage structure provided in this embodiment of the application features an elastic sealing structure 20, with each linear groove 2012 extending to the inner peripheral wall of the inlet hole 2011. This allows the sealing structure 20 to deform at the linear groove 2012, thereby enlarging the inlet hole 2011. This allows for a smaller diameter of the inlet hole 2011 before deformation at the linear groove 2012, and the linear groove 2012's linear shape results in a smaller width. Consequently, the inlet groove 201 has a smaller diameter, preventing the aerosol-generating matrix in the liquid storage chamber 101 from overflowing when the cover 30 is accidentally opened, thus reducing the risk of leakage.

[0045] Furthermore, the sealing structure 20 elastically abuts against the housing assembly 10 and the cover 30, so that the friction between the sealing structure 20 and the cover 30 provides a certain resistance to the cover 30 opening the liquid inlet 201. This can reduce the risk of the cover 30 being accidentally touched and opening the liquid inlet 201, thereby reducing the risk of leakage of the aerosol generation matrix in the liquid storage chamber 101 after the cover 30 opens the liquid inlet 201.

[0046] In some embodiments, such as Figure 3 and Figure 4As shown, in the extension direction of the linear groove 2012, the size of the linear groove 2012 is larger than the size of the liquid inlet hole 2011. This helps to maximize the enlargement of the liquid inlet hole 2011 when the sealing structure 20 deforms at the linear groove 2012, thereby improving the replenishment efficiency of the aerosol generation matrix into the liquid storage chamber 101 through the liquid inlet hole 2011. Based on this, the design of the liquid inlet hole 2011 helps to reduce its diameter before deformation at the linear groove 2012 in the sealing structure 20, thereby further reducing the risk of leakage of the aerosol generation matrix through the liquid inlet groove 201.

[0047] In some embodiments, please refer to the following: Figure 3 and Figure 4 Furthermore, in conjunction with other accompanying drawings, multiple linear grooves 2012 are spaced apart and evenly distributed along the circumference of the liquid inlet hole 2011.

[0048] This design helps to maximize the enlargement of the inlet hole 2011 when the sealing structure 20 deforms at the linear groove 2012, thereby improving the replenishment efficiency of the aerosol generation matrix into the storage chamber 101 through the inlet hole 2011. Based on this, the design of the inlet hole 2011 helps to reduce its diameter before deformation at the linear groove 2012 of the sealing structure 20, further reducing the risk of leakage of the aerosol generation matrix through the inlet groove 201.

[0049] In some embodiments, please refer to the following: Figure 3 and Figure 4 And in conjunction with other accompanying drawings. There are two linear grooves 2012, which are arranged opposite to each other on the inner peripheral wall of the liquid inlet hole 2011.

[0050] This design has two advantages. First, when the sealing structure 20 deforms at the linear groove 2012, it helps to maximize the enlargement of the liquid inlet 2011, thereby improving the replenishment efficiency of the aerosol generating matrix into the storage chamber 101 through the liquid inlet 2011. Second, it can reduce the area of ​​the cross-section of the liquid inlet groove 201 perpendicular to the first direction Z, which helps to reduce the risk of leakage of the aerosol generating matrix through the liquid inlet groove 201.

[0051] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The sealing structure 20 includes a sealing body 21 and a sealing rib 22. The sealing body 21 is disposed on the housing assembly 10, covering the liquid storage cavity 101, and the liquid inlet groove 201 is disposed on the sealing body 21. The sealing rib 22 is disposed on the side of the sealing body 21 away from the liquid storage cavity 101, and at least a portion of the sealing rib 22 surrounds the outer periphery of the liquid inlet groove 201. The side of the sealing rib 22 away from the sealing body 21 is used to elastically abut against the cover member 30.

[0052] The sealing body 21 is the main structure of the sealing structure 20, and the sealing rib 22 is a rib-like structure on the sealing structure 20. Both the sealing body 21 and the sealing rib 22 have sealing performance and elasticity.

[0053] Understandably, the sealing body 21 covers the liquid storage cavity 101, so that the sealing body 21 can achieve a sealing effect on the liquid storage cavity 101.

[0054] Understandably, in the direction where the sealing body 21 covers the liquid storage cavity 101, the liquid inlet groove 201 penetrates the sealing body 21, so that the liquid inlet groove 201 and the liquid storage cavity 101 are connected.

[0055] By adopting the above technical solution, when the cover 30 closes the liquid inlet 201, the side of the sealing rib 22 away from the sealing body 21 elastically abuts against the cover 30. This improves the sealing effect on the liquid inlet 201, thereby minimizing the leakage of the aerosol generation matrix in the liquid storage chamber 101 through the liquid inlet 201. Furthermore, it ensures suitable friction between the sealing structure 20 and the cover 30, providing appropriate resistance to the movement of the cover 30 and reducing the risk of the cover 30 being accidentally opened and the liquid inlet 201 being opened.

[0056] In some embodiments, please refer to the following: Figures 1 to 4 And in conjunction with other accompanying drawings. At least a portion of the sealing structure 20 covers one end of the liquid storage chamber 101 along the first direction Z. The liquid inlet groove 201 extends through the sealing structure 20 along the first direction Z. A cover 30 is disposed at the end of the housing assembly 10 having the sealing structure 20 along the first direction Z, and the cover 30 is configured to reciprocate relative to the housing assembly 10 along the second direction X to open or close the liquid inlet groove 201. The first direction Z and the second direction X are perpendicular.

[0057] Specifically, the sealing body 21 covers one end of the liquid storage cavity 101 along the first direction Z, and the sealing rib 22 is located at the end of the sealing body 21 away from the liquid storage cavity 101 along the first direction Z, and is used to abut against the cover member 30 along the first direction Z.

[0058] Understandably, when the cover 30 moves relative to the housing assembly 10 along the second direction X, it can move to the point where at least a portion of the cover 30 does not cover the side of the inlet channel 201 away from the liquid storage chamber 101 along the first direction Z, so that the inlet channel 201 is opened by the cover 30; or it can move to the point where the cover 30 covers the side of the inlet channel 201 away from the liquid storage chamber 101 along the first direction Z, so that the inlet channel 201 is closed by the cover 30.

[0059] With this configuration, the user can open or close the liquid inlet 201 by pushing the cover 30 along the second direction X, making the opening and closing of the liquid inlet 201 very convenient.

[0060] In some embodiments, please refer to the following: Figures 3 to 7 And in conjunction with other accompanying figures. Figure 5 for Figure 1 A sectional view along AA, Figure 6 for Figure 5 Enlarged view at point B in the middle. Figure 7 This is a perspective view of the cover 30 of an aerosol generating apparatus provided in some embodiments of this application. One of the housing assembly 10 and the cover 30 is provided with a first groove 301, and the other is provided with a guide structure 40. The guide structure 40 is inserted into the first groove 301 along a first direction Z and is used to slide along the first groove 301 in a second direction X.

[0061] In some possible designs, such as Figures 3 to 7 As shown, the cover 30 has a first groove 301 on the side facing the housing assembly 10 along the first direction Z, and the guide structure 40 is fixed to the housing assembly 10. Alternatively, in some other possible designs, the housing assembly 10 has a first groove 301 on the side facing the cover 30 along the first direction Z, and the guide structure 40 is fixed to the cover 30.

[0062] Understandably, the first groove 301 extends along the second direction X. When the cover 30 reciprocates relative to the housing assembly 10 along the second direction X, the guide structure 40 reciprocates along the first groove 301 in the second direction X.

[0063] Understandably, the guide structure 40 is confined within the first groove 301 along the third direction Y, so that the first groove 301 can guide the reciprocating motion of the guide structure 40 in the second direction X, thereby guiding the relative movement of the cover 30 and the housing assembly 10 in the second direction X. This makes it easier for the user to push the cover 30 to open or close the liquid inlet 201. Based on this, the cover 30 and the housing assembly 10 are confined in the third direction Y.

[0064] This configuration allows the cover 30 to reliably reciprocate along the second direction X, thereby reliably opening or closing the liquid inlet tank 201.

[0065] In some embodiments, such as Figures 3 to 7 As shown, there are multiple first slide grooves 301, which are spaced apart along the third direction Y. There are also multiple guide structures 40, which are spaced apart along the third direction Y, and each guide structure 40 is inserted into a first slide groove 301.

[0066] As an example, there are two first chute 301s and two guide structures 40.

[0067] This configuration improves the guiding properties of the cover 30 in the reciprocating motion relative to the housing assembly 10 along the second direction X, and also improves the reliability of limiting the stroke of the relative movement of the cover 30 and the housing assembly 10 in the second direction X.

[0068] In some embodiments, please refer to the following: Figures 3 to 7 In conjunction with other accompanying drawings, the first groove 301 has a first groove wall 3011 and a second groove wall 3012 on opposite sides along the second direction X, and the guide structure 40 is located between the first groove wall 3011 and the second groove wall 3012 along the second direction X.

[0069] This configuration allows the first groove 301 to limit the travel of the guide structure 40 in the second direction X, thereby limiting the travel of the cover 30 in the second direction X within the housing assembly 10. Thus, the interlocking action of the first groove 301 and the guide structure 40 improves the problem of the cover 30 dislodging from the housing assembly 10 during the opening or closing of the liquid inlet 201.

[0070] In some embodiments, please refer to the following: Figure 5 and Figure 6 And in conjunction with other accompanying drawings. The guide structure 40 includes a fixing part 41 and a first guide part 42 disposed on the fixing part 41. The fixing part 41 is fixed to the housing assembly 10 or the cover 30, and the first guide part 42 is inserted into the first slide groove 301 along the first direction Z. In the third direction Y, the size of the fixing part 41 is larger than the size of the first guide part 42, the size of the fixing part 41 is larger than the size of the first slide groove 301, and the size of the first slide groove 301 is larger than the size of the first guide part 42. The third direction Y is perpendicular to the first direction Z and perpendicular to the second direction X.

[0071] Understandably, when the guide structure 40 is fixed to the housing assembly 10, such as Figure 2 and Figure 3 As shown, the fixing part 41 is fixed to the housing assembly 10. When the guide structure 40 is fixed to the cover 30, the fixing part 41 is fixed to the cover 30.

[0072] Specifically, the first guide portion 42 and the fixing portion 41 are arranged along the first direction Z.

[0073] The size of the first slide groove 301 is larger than the size of the first guide part 42, so that the first guide part 42 can be inserted into the first slide groove 301 along the first direction Z, and can also reciprocate along the first slide groove 301 in the second direction X.

[0074] By making the size of the fixing part 41 larger than the size of the first guide part 42, and the size of the fixing part 41 larger than the size of the first slide groove 301, when the fixing part 41 is fixed to the housing assembly 10, as... Figure 5 and Figure 6 As shown, the portion of the cover 30 located outside the first slide groove 301 along the third direction Y can limit the fixing part 41 along the first direction Z, thereby improving the fixing reliability of the fixing part 41 on the housing assembly 10. When the fixing part 41 is fixed to the cover 30, the portion of the housing assembly 10 located outside the first slide groove 301 along the third direction Y can limit the fixing part 41 along the first direction Z, thereby improving the fixing reliability of the fixing part 41 on the cover 30. This arrangement allows the guide structure 40 to be reliably assembled, reliably providing guidance and limiting functions for the relative movement between the cover 30 and the housing assembly 10.

[0075] In some embodiments, please refer to the following: Figures 2 to 7 In conjunction with other accompanying drawings, a first groove 301 is provided on the side of the cover 30 facing the housing assembly 10 along the first direction Z. The housing assembly 10 is provided with a mounting hole 107 on the side of the cover 30 along the first direction Z near the cover 30. The fixing part 41 is fixed in the mounting hole 107, and at least a portion of the first guide part 42 is located outside the mounting hole 107.

[0076] Among them, the mounting hole 107 can be a countersunk hole.

[0077] This arrangement allows the first groove 301 to be disposed on the cover 30 and the guide structure 40 to be disposed on the housing assembly 10, which helps to reduce the weight of the cover 30 and facilitates the reciprocating motion of the cover 30 relative to the housing assembly 10 in the second direction X.

[0078] The fixing part 41 and the mounting hole 107 may be, but are not limited to, interference fit.

[0079] In some embodiments, the guide structure 40 is an elastic structure.

[0080] The guide structure 40 can be a spring, a spring sheet, or other similar structure.

[0081] By adopting the above technical solution, when the guide structure 40 is fixed to the housing assembly 10, the cover 30 can be pressed against the guide structure 40 along the first direction Z to compress the guide structure 40, and then the cover 30 can be pushed along the second direction X until the guide structure 40 is inserted into the first sliding groove 301, thus realizing the assembly of the liquid storage structure. When the guide structure 40 is fixed to the cover 30, the housing assembly 10 can be pressed against the guide structure 40 along the first direction Z to compress the guide structure 40, and then the cover 30 can be pushed along the second direction X until the guide structure 40 is inserted into the first sliding groove 301, thus realizing the assembly of the liquid storage structure. This arrangement makes the assembly operation of the liquid storage structure relatively simple.

[0082] Both the fixing part 41 and the first guide part 42 can be elastic structures. Alternatively, the fixing part 41 can be an elastic structure, while the first guide part 42 can be a non-elastic structure. Or, the fixing part 41 can be a non-elastic structure, while the first guide part 42 can be an elastic structure.

[0083] In some embodiments, please refer to the following: Figure 5 and Figure 6 And in conjunction with other attached diagrams. The guide structure 40 is a spring pin.

[0084] Specifically, the fixing part 41 can be a non-elastic structure, while the first guide part 42 is an elastic structure. This facilitates the improvement of the fixing reliability of the fixing part 41 on the housing assembly 10 or the cover 30, and also makes the guide structure 40 have elastic properties.

[0085] By setting the guide structure 40 as a spring pin, the structure of the guide structure 40 is relatively simple and easy to obtain.

[0086] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The housing assembly 10 has a mounting groove 102 at one end along the first direction Z, the liquid storage chamber 101 is exposed within the mounting groove 102, and at least a portion of the sealing structure 20 is disposed within the mounting groove 102. The mounting groove 102 has a second sliding groove 103 on at least one side along the third direction Y, and the cover 30 has a second guide portion 311 on at least one side along the third direction Y. The second guide portion 311 is confined within the second sliding groove 103 along the first direction Z, and is used to reciprocate along the second sliding groove 103 in the second direction X. One end of the second sliding groove 103 along the second direction X has an opening 104 for the second guide portion 311 to enter.

[0087] Understandably, in the first direction Z, the housing assembly 10 has a mounting groove 102 at one end near the liquid inlet 201, so that the liquid inlet 201 can be exposed in the mounting groove 102.

[0088] In some possible designs, such as Figures 2 to 4 As shown, the mounting groove 102 has second sliding grooves 103 on both sides opposite to each other along the third direction Y, and the cover 30 has second guide portions 311 on both sides opposite to each other along the third direction Y. The second guide portions 311 on both sides of the cover 30 along the third direction Y are respectively inserted into the second sliding grooves 103 on both sides of the mounting groove 102 along the third direction Y, so that the cover 30 can be limited between the groove walls of the second sliding grooves 103 on both sides along the third direction Y, realizing the relative positioning of the cover 30 and the housing assembly 10 in the third direction Y, and improving the guiding of the cover 30 relative to the housing assembly 10 in the second direction X. Alternatively, in some other possible designs, the mounting groove 102 has a second sliding groove 103 on one side along the third direction Y, and the cover 30 has a second guide portion 311 on one side along the third direction Y.

[0089] The second guide portion 311 is positioned within the second slide groove 103 along the first direction Z, which can realize the relative positioning of the cover 30 and the housing assembly 10 in the first direction Z, and improve the guiding performance of the cover 30 relative to the reciprocating motion of the housing assembly 10 along the second direction X.

[0090] By adopting the above technical solution, the second guide portion 311 of the cover 30 can be slid into the second groove 103 through the opening 104 along the second direction X. Then, the cover 30 can be slid relative to the housing assembly 10 along the second direction X, so that the guide structure 40 can be inserted into the first groove 301, thereby realizing the assembly of the liquid storage structure. In this way, the assembly operation of the liquid storage structure is very simple.

[0091] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The housing assembly 10 is provided with a main air passage 105 and an exhaust port 106. The main air passage 105, the liquid inlet 201, and the exhaust port 106 are spaced apart, and the exhaust port 106 communicates with the liquid storage chamber 101. The cover 30 includes a cover body 31 and a suction nozzle 32 provided on the cover body 31. The cover body 31 is movably connected to the housing assembly 10 and can reciprocate relative to the housing assembly 10 to open or close the liquid inlet 201. The sealing structure 20 elastically abuts against the cover body 31, and the suction nozzle 32 is used to communicate with the main air passage 105 when the cover body 31 closes the liquid inlet 201.

[0092] Understandably, the vent 106 is located at one end of the housing assembly 10 along the first direction Z near the liquid inlet 201, and the main vent 105 is exposed at one end of the housing assembly 10 along the first direction Z near the liquid inlet 201.

[0093] The cover 31 is the main structure of the cover assembly 30. The cover 31 is movably connected to one end of the housing assembly 10 along the first direction Z near the liquid inlet tank 201.

[0094] The housing assembly 10 is also provided with an exhaust port 106 that communicates with the liquid storage chamber 101. When the aerosol generation matrix is ​​added to the liquid storage chamber 101 through the liquid inlet 201, the gas in the liquid storage chamber 101 can be discharged through the exhaust port 106. This can improve the problem of leakage of the aerosol generation matrix in the liquid storage chamber 101 through the main air passage 105 caused by the pressure imbalance.

[0095] When the liquid inlet 201 is closed by the cover 31, the suction nozzle 32 is connected to the main air channel 105, so that the aerosol generated in the liquid storage structure can be misted through the main air channel 105 and the suction nozzle 32 in sequence.

[0096] Please refer to the following: Figures 1 to 3 The aerosol generating device provided in this application includes a liquid storage structure and an atomizing core, with the atomizing core disposed within the liquid storage structure. The liquid storage structure in this embodiment is the same as that in the above embodiments; please refer to the relevant descriptions of the liquid storage structures in the above embodiments for details, which will not be repeated here.

[0097] Specifically, the atomizing core is located within the main air passage 105 of the liquid storage structure. The atomizing core refers to a structure that generates heat when energized, thereby heating the aerosol-generating matrix and causing it to atomize into an aerosol.

[0098] The aerosol generating apparatus provided in this application reduces the risk of leakage of the aerosol generating matrix in the liquid storage chamber 101 by adopting the liquid storage structure involved in the above embodiments.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
