Description

Technical Field

[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 housing assembly and a nozzle structure. The housing assembly contains a reservoir for storing the aerosol generating matrix, and the nozzle structure is movably mounted on the housing assembly to cover the reservoir. By pushing the nozzle structure, the user can open the reservoir, allowing the user to add the aerosol generating matrix into the reservoir.

[0004] Specifically, the housing assembly typically has a guide structure on the side facing the nozzle structure, and the nozzle structure has a groove on the side facing the housing assembly. The guide structure is inserted into the groove and is used to slide along the groove to open or close the liquid storage chamber.

[0005] However, the insertion of the guide structure into the groove of the nozzle structure makes the assembly of the housing assembly, guide structure and nozzle structure quite difficult.

[0057] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0058] 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.

[0059] Aerosol generating devices typically include a housing assembly and a nozzle structure. The housing assembly contains a reservoir for storing the aerosol generating matrix, and the nozzle structure is movably mounted on the housing assembly to cover the reservoir. By pushing the nozzle structure, the user can open the reservoir, allowing the user to add the aerosol generating matrix into the reservoir.

[0060] Specifically, the housing assembly typically has a guide structure on the side facing the nozzle structure, and the nozzle structure has a groove on the side facing the housing assembly. The guide structure is inserted into the groove and is used to slide along the groove to open or close the liquid storage chamber.

[0061] However, the assembly of the housing assembly, guide structure, and nozzle structure is difficult due to the guide structure being inserted into the groove of the nozzle structure, which makes the aerosol generation device more difficult to assemble.

[0062] In some cases, the guide structure can be set as an elastic structure, such as an assembly of ball bearings and springs, or a spring needle. In this case, during the assembly of the aerosol generator, the elastic structure needs to be installed on the housing assembly first, then the nozzle assembly pre-compresses the elastic structure, and then the nozzle structure is slid into the housing assembly until the elastic structure is inserted into the groove. Because of this, the assembly of the aerosol generator requires pre-compressing the elastic structure, and this pre-compression must be maintained while sliding the nozzle structure into the housing assembly until it is inserted into the groove. This makes the assembly of the aerosol generator more difficult and affects assembly efficiency.

[0063] Based on this, the embodiments of this application provide a liquid storage structure and an aerosol generating device, which reduces the assembly difficulty of the liquid storage structure.

[0064] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments:

[0065] Please refer to the following: Figures 1 to 7 ,in, Figure 1 This is a perspective view of the aerosol generating device provided in some embodiments of this application when the liquid inlet tank 102 is closed. Figure 2 This is a perspective structural view of the housing 11 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 apparatus provided in some embodiments of this application when the liquid inlet tank 102 is opened. Figure 5 for Figure 1 A sectional view along AA, Figure 6 for Figure 5 Enlarged view at point B in the middle. Figure 7This is a perspective view of the cover 20 of an aerosol generating device provided in some embodiments of this application. The liquid storage structure provided in this application includes a housing assembly 10, a cover 20, and an elastic structure 30. The housing assembly 10 has a liquid storage chamber 101, and one end of the housing assembly 10 along a first direction Z has a liquid inlet groove 102, which communicates with the liquid storage chamber 101. The cover 20 is movably connected to the end of the housing assembly 10 with the liquid inlet groove 102 along the first direction Z. The cover 20 can reciprocate relative to the housing assembly 10 along a second direction X to open or close the liquid inlet groove 102. The elastic structure 30 includes a fixing member 31 and a spring piece 32 disposed on the fixing member 31. At least a portion of the spring piece 32 extends along the first direction Z in the second direction X. One of the housing assembly 10 and the cover 20 is provided with a first sliding groove 201, and the other is fixed with the fixing member 31. At least a portion of the spring piece 32 is inserted into the first groove 201 along the first direction Z. The spring piece 32 is used to slide along the first groove 201 in the second direction X, and the spring piece 32 is limited to being located within the first groove 201 along the second direction X. The first direction Z and the second direction X are perpendicular.

[0066] The liquid storage chamber 101 is a cavity formed inside the shell assembly 10. The liquid storage chamber 101 can be used, but is not limited to, to store the aerosol generation matrix.

[0067] The cover 20 is movably connected to one end of the housing assembly 10 having a liquid inlet groove 102 along the first direction Z. This does not mean that the cover 20 and the housing assembly 10 must be strictly distributed along the first direction Z. Rather, the cover 20 is located approximately on the end structure of the housing assembly 10 having a liquid inlet groove 102 along the first direction Z.

[0068] Understandably, at least a portion of the cover 20 and the housing assembly 10 are distributed along the first direction Z. Specifically, in the first direction Z, at least a portion of the cover 20 is located on the side of the inlet tank 102 away from the reservoir 101, such that the cover 20 can be used to cover and close the inlet tank 102.

[0069] The cover 20 is capable of reciprocating relative to the housing assembly 10 along the second direction X to open or close the liquid inlet 102. Specifically, when the cover 20 moves relative to the housing assembly 10 along the second direction X, it can move until at least a portion of the cover 20 does not cover the side of the liquid inlet 102 away from the liquid storage chamber 101 along the first direction Z, thus opening the liquid inlet 102; or it can move until the cover 20 covers the side of the liquid inlet 102 away from the liquid storage chamber 101 along the first direction Z, thus closing the liquid inlet 102. When the cover 20 opens the liquid inlet 102, the user can replenish the aerosol generation matrix into the liquid storage chamber 101 through the liquid inlet 102. When the cover 20 closes the liquid inlet 102, it provides protection for both the liquid inlet 102 and the liquid storage chamber 101.

[0070] In the second direction X, at least a portion of the spring piece 32 extends along the first direction Z, meaning that at least a portion of the spring piece 32 extends along both the second and first directions X. That is, at least a portion of the spring piece 32 extends along the direction between the first and second directions X. Specifically, on the same projection plane perpendicular to the third direction Y, the orthographic projection of at least a portion of the spring piece 32 extends along the direction between the first and second directions Z and X. The spring piece 32 can extend in a curved or straight line.

[0071] Among them, the third direction Y is perpendicular to the first direction Z, and the third direction Y is perpendicular to the second direction X.

[0072] In some possible designs, such as Figures 2 to 7 As shown, the cover 20 has a first groove 201 on the side facing the housing assembly 10 along the first direction Z, and the fixing member 31 is fixed to the housing assembly 10. Alternatively, in some other possible designs, the housing assembly 10 has a first groove 201 on the side facing the cover 20 along the first direction Z, and the fixing member 31 is fixed to the cover 20.

[0073] Understandably, the first slide groove 201 extends along the second direction X. When the cover 20 reciprocates relative to the housing assembly 10 along the second direction X, the spring 32 reciprocates along the first slide groove 201 in the second direction X.

[0074] The spring piece 32 is limited to being located within the first groove 201 along the second direction X. This means that the first groove 201 has groove walls on both opposite sides along the second direction X, and the spring piece 32 is limited to being located between the two opposite groove walls along the second direction X of the first groove 201. That is, the first groove 201 is used to limit the travel of the spring piece 32 in the reciprocating motion along the second direction X, thereby limiting the travel of the cover piece 20 in the reciprocating motion of the housing assembly 10 along the second direction X. In this way, the plug-in cooperation of the first groove 201 and the elastic structure 30 improves the problem of the cover piece 20 dislodging from the housing assembly 10 during the opening or closing of the liquid inlet groove 102.

[0075] Understandably, the spring piece 32 is confined within the first slide groove 201 along the third direction Y, so that the first slide groove 201 can guide the reciprocating motion of the spring piece 32 in the second direction X, thereby guiding the relative movement of the cover piece 20 and the housing assembly 10 in the second direction X. This makes it easier for the user to push the cover piece 20 to open or close the liquid inlet groove 102. Based on this, the cover piece 20 and the housing assembly 10 are confined in the third direction Y.

[0076] The liquid storage structure provided in this application embodiment, by having at least a portion of the spring piece 32 extend along the first direction Z in the second direction X, allows the spring piece 32 to easily deform effortlessly under the action of the cover 20 and the housing assembly 10 when the cover 20 and the housing assembly 10 move relative to each other in the second direction X along the extending direction of the spring piece 32. In this way, the user can directly move the cover 20 and the housing assembly 10 relative to each other in the second direction X along the extending direction of the spring piece 32 until the spring piece 32 is located at the first sliding groove 201 and then reset to insert into the first sliding groove 201, thus realizing the assembly operation of the liquid storage structure without the need for special pre-compression of the elastic structure 30, nor the need to maintain a special pre-compression operation on the elastic structure 30 when the cover 20 and the housing assembly 10 move relative to each other in the second direction X. This design makes the assembly operation of the liquid storage structure very simple and effortless, reducing the assembly difficulty of the liquid storage structure.

[0077] It should be further noted that when the fastener 31 is fixed to the housing assembly 10, such as Figures 2 to 7As shown, at least a portion of the spring piece 32 extends along the first direction Z in the second direction X. Specifically, in the first unidirectional extension direction a, at least a portion of the spring piece 32 extends from the housing assembly 10 toward the cover piece 20 in the first direction Z. The first unidirectional extension direction a is parallel to the second direction X. Therefore, the relative movement of the cover piece 20 and the housing assembly 10 in the second direction X along the extension direction of the spring piece 32 means that the cover piece 20 moves relative to the housing assembly 10 and the elastic structure 30 along the first unidirectional extension direction a, causing the cover piece 20 to move along the spring piece 32 to compress the spring piece 32, making the spring piece 32 easily deformed by force. Therefore, after the liquid storage structure is assembled, when the cover piece 20 is moved relative to the housing assembly 10 in a direction opposite to the first unidirectional extension direction a, the spring piece 32 can abut against the groove wall of the first slide groove 201 along the first unidirectional extension direction a, increasing the difficulty for the spring piece 32 to disengage from the first slide groove 201.

[0078] When the fastener 31 is fixed to the cover 20, at least a portion of the spring piece 32 extends along the first direction Z in the second direction X. Specifically, in the second unidirectional extension direction, at least a portion of the spring piece 32 extends from the cover 20 toward the housing assembly 10 in the first direction Z. The second unidirectional extension direction is parallel to the second direction X. Therefore, the relative movement of the cover 20 and the housing assembly 10 in the second direction X along the extension direction of the spring piece 32 means that the cover 20 and the elastic structure 30 move together relative to the housing assembly 10 in a direction opposite to the second unidirectional extension direction. This causes the housing assembly 10 to move along the spring piece 32 to compress the spring piece 32, making the spring piece 32 easily deformed without effort. Therefore, after the liquid storage structure is assembled, after moving the cover 20 relative to the housing assembly 10 along the second unidirectional extension direction, the spring piece 32 can abut against the groove wall of the first groove 201 along the second unidirectional extension direction, increasing the difficulty for the spring piece 32 to detach from the first groove 201.

[0079] In some embodiments, please refer to the following: Figure 5 and Figure 6 Furthermore, in conjunction with other accompanying drawings, at least a portion of the orthographic projection of the spring piece 32 is tilted relative to the first direction Z and the second direction X on the same projection plane perpendicular to the third direction Y.

[0080] By extending the spring tab 32 at an angle, when the fixing member 31 is fixed to the housing assembly 10, the cover member 20 can move along the second direction X along the spring tab 32 relative to the housing assembly 10 to compress the spring tab 32; when the fixing member 31 is fixed to the cover member 20, the housing assembly 10 can move along the second direction X along the spring tab 32 relative to the cover member 20 to compress the spring tab 32. This further simplifies and reduces the effort required to assemble the liquid storage structure.

[0081] 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 first mounting groove 103 at one end along the first direction Z, and the liquid inlet groove 102 is exposed within the first mounting groove 103. The first mounting groove 103 has a second sliding groove 104 on at least one side along the third direction Y, and the cover 20 has a guide portion 211 on at least one side along the third direction Y. The guide portion 211 is confined within the second sliding groove 104 along the first direction Z, and is used to reciprocate along the second sliding groove 104 in the second direction X. The second sliding groove 104 has an opening 105 at at least one end along the second direction X, which allows the guide portion 211 to slide into the second sliding groove 104 along the second direction X.

[0082] Understandably, in the first direction Z, the housing assembly 10 has a first mounting groove 103 at one end with a liquid inlet groove 102, so that the liquid inlet groove 102 can be exposed in the first mounting groove 103.

[0083] In some possible designs, such as Figures 2 to 4 As shown, the first mounting groove 103 has second sliding grooves 104 on both sides opposite to each other along the third direction Y, and the cover 20 has guide portions 211 on both sides opposite to each other along the third direction Y. The guide portions 211 on both sides of the cover 20 along the third direction Y are respectively inserted into the second sliding grooves 104 on both sides of the first mounting groove 103 along the third direction Y, so that the cover 20 can be limited between the groove walls of the second sliding grooves 104 on both sides along the third direction Y, realizing the relative positioning of the cover 20 and the housing assembly 10 in the third direction Y, and improving the guiding of the cover 20 relative to the reciprocating movement of the housing assembly 10 in the second direction X. Alternatively, in some other possible designs, the first mounting groove 103 has a second sliding groove 104 on one side along the third direction Y, and the cover 20 has a guide portion 211 on one side along the third direction Y.

[0084] The guide portion 211 is positioned within the second slide groove 104 along the first direction Z, which can realize the relative positioning of the cover 20 and the housing assembly 10 in the first direction Z, and improve the guiding performance of the cover 20 relative to the reciprocating motion of the housing assembly 10 in the second direction X.

[0085] In some possible designs, such as Figures 2 to 4 As shown, the second slide 104 has an opening 105 at one end along the second direction X. Alternatively, in some other possible designs, the second slide 104 has openings 105 at both opposite ends along the second direction X.

[0086] By adopting the above technical solution, the guide portion 211 of the cover 20 can be slid into the second groove 104 along the second direction X through the opening 105. Then, the cover 20 can be slid relative to the housing assembly 10 along the second direction X, so that the spring piece 32 can be inserted into the first groove 201, thereby realizing the assembly of the liquid storage structure. In this way, the assembly operation of the liquid storage structure is very simple.

[0087] In some embodiments, please refer to the following: Figures 2 to 4 Furthermore, in conjunction with other accompanying drawings, the second groove 104 has an opening 105 at one end along the second direction X.

[0088] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. A first groove 201 is provided on the side of the cover 20 facing the housing assembly 10 along the first direction Z, and a fastener 31 is fixed to the housing assembly 10. At least a portion of the spring 32 extends along the first direction Z from the housing assembly 10 toward the cover 20 in the direction of the opening 105 pointing in the second direction X toward the spring 32.

[0089] Understandably, the opening 105 points in the direction of the second direction X toward the spring 32, which is the first unidirectional extension direction a mentioned above.

[0090] This design allows the guide portion 211 of the cover 20 to enter the second groove 104 from the opening 105 along the first unidirectional direction. As the guide portion 211 continues to slide along the second groove 104 in the first unidirectional direction, the cover 20 can move along the spring piece 32 in the second direction X to compress the spring piece 32, thus facilitating the deformation of the spring piece 32 and its insertion into the first groove 201. This makes the assembly of the liquid storage structure very simple and labor-saving.

[0091] Furthermore, after the liquid storage structure is assembled, the extension scheme of the spring 32 enables the spring 32 to be reliably limited in the first slide groove 201 along the first unidirectional direction, thereby reducing the risk of the cover 20 being dislodged from the housing assembly 10 in the opposite direction to the first unidirectional direction.

[0092] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The second slide 104 has a limiting part 111 at one end away from the opening 105 along the second direction X. The limiting part 111 is used to limit the guide part 211 along the second direction X.

[0093] The limiting part 111 may be, but is not limited to, the side wall of the second slide 104 away from the opening 105 along the second direction X.

[0094] By adopting the above technical solution, the limiting part 111 can restrict the sliding stroke of the guide part 211 along the second slide groove 104 in the first unidirectional direction, that is, restrict the stroke of the cover 20 relative to the housing assembly 10 in the first unidirectional direction, thereby reducing the risk of the cover 20 detaching from the housing assembly 10 in the first unidirectional direction. In this way, the assembly reliability of the liquid storage structure is improved, and the risk of the cover 20 detaching from the housing assembly 10 is reduced.

[0095] In some embodiments, please refer to the following: Figure 2 , Figure 3 , Figure 7 and Figure 8 And in conjunction with other accompanying figures. Figure 8 This is a perspective view of the elastic structure 30 of the aerosol generating apparatus provided in some embodiments of this application. There are multiple first slide grooves 201, spaced apart along the third direction Y. The elastic structure 30 includes multiple spring pieces 32 spaced apart along the third direction Y on the fixing member 31, each spring piece 32 being inserted into a first slide groove 201.

[0096] As an example, there are two of each of the first slide groove 201 and the spring piece 32.

[0097] This configuration improves the guiding properties of the cover 20 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 20 and the housing assembly 10 in the second direction X.

[0098] In addition, multiple spring clips 32 are all mounted on the fixing member 31, that is, the fixing member 31 fixes the multiple spring clips 32 together, which can improve the reliability of fixing the fixing member 31 to the housing assembly 10 or the cover member 20.

[0099] Among them, the elastic structure 30 may be, but is not limited to, a one-piece molded structure.

[0100] In some embodiments, please refer to the following: Figure 2 and Figure 3 In conjunction with other accompanying drawings, the housing assembly 10 has a second mounting groove 106 at one end along the first direction Z. The second mounting groove 106 and the liquid inlet groove 102 are spaced apart, and the fastener 31 is fixed in the second mounting groove 106.

[0101] Understandably, the second mounting groove 106 is provided at one end of the housing assembly 10 along the first direction Z where it has a liquid inlet groove 102.

[0102] The second mounting slot 106 and the first mounting slot 103 can be interconnected. For example, the second mounting slot 106 can be located at the bottom of the first mounting slot 103. Alternatively, the second mounting slot 106 and the first mounting slot 103 can be spaced apart.

[0103] The fastener 31 is fixed in the second mounting groove 106. On the one hand, this facilitates the positioning of the fastener 31 on the housing assembly 10, so that the fastener 31 can be fixed to the housing assembly 10. On the other hand, the second mounting groove 106 can limit the position of the fastener 31, thereby improving the installation reliability of the elastic structure 30 on the housing assembly 10.

[0104] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The housing assembly 10 includes a housing 11 and a sealing structure 12. The housing 11 has a liquid storage chamber 101. At least a portion of the sealing structure 12 is located at one end of the housing 11 along the first direction Z and covers the liquid storage chamber 101. The sealing structure 12 has a liquid inlet groove 102. The sealing structure 12 is an elastic structure 30 and elastically abuts against the cover member 20 and the housing 11 along the first direction Z. The cover member 20 is movably connected to the end of the housing 11 along the first direction Z near the liquid inlet groove 102. One of the housing 11 and the cover member 20 has a first sliding groove 201, and the other is fixed with a fixing member 31.

[0105] The housing 11 is the main structure of the housing assembly 10.

[0106] The sealing structure 12 is a structure with sealing performance and elastic properties. The sealing structure 12 can be a silicone gasket, a rubber gasket, etc.

[0107] The sealing structure 12 elastically abuts against the cover 20 and the housing 11, creating a predetermined frictional force between them. This frictional force provides resistance to the movement of the cover 20 relative to the housing assembly 10 along the second direction X, thus providing resistance to opening or closing the liquid inlet 102. This reduces the risk of accidental opening of the liquid inlet 102 by the cover 20, thereby reducing the risk of leakage of the aerosol generation matrix from the storage chamber 101 through the liquid inlet 102 after the cover 20 is opened.

[0108] In some embodiments, please refer to the following: Figure 2 and Figure 3And in conjunction with other accompanying drawings. The sealing structure 12 includes a sealing body 121 and a sealing rib 122. The sealing body 121 is located at one end of the housing 11 along the first direction Z and covers the liquid storage cavity 101, and the sealing body 121 is provided with a liquid inlet groove 102. The sealing rib 122 is located on the side of the sealing body 121 along the first direction Z away from the liquid storage cavity 101, and at least a portion of the sealing rib 122 surrounds the outer periphery of the liquid inlet groove 102. The side of the sealing rib 122 along the first direction Z away from the sealing body 121 is used to elastically abut against the cover member 20.

[0109] The sealing body 121 is the main structure of the sealing structure 12, and the sealing rib 122 is a rib-like structure on the sealing structure 12. Both the sealing body 121 and the sealing rib 122 have sealing performance and elasticity.

[0110] Understandably, the liquid inlet 102 penetrates the sealing body 121 along the first direction Z, so that the liquid inlet 102 and the liquid storage chamber 101 are connected.

[0111] By adopting the above technical solution, when the cover 20 closes the liquid inlet 102, the sealing rib 122 elastically abuts against the cover 20 on the side away from the sealing body 121 along the first direction Z. This improves the sealing effect on the liquid inlet 102, thereby minimizing the leakage of the aerosol generation matrix in the liquid storage cavity 101 through the liquid inlet 102. Furthermore, it ensures suitable friction between the sealing structure 12 and the cover 20, providing appropriate resistance to the movement of the cover 20 and reducing the risk of the cover 20 being accidentally opened and the liquid inlet 102 being opened.

[0112] In some embodiments, please refer to Figure 3 And in conjunction with other accompanying drawings. The liquid inlet tank 102 includes a liquid inlet hole 1021 and a plurality of spaced linear grooves 1022, each linear groove 1022 extending to the inner peripheral wall of the liquid inlet hole 1021, and both the liquid inlet hole 1021 and the linear grooves 1022 are connected to the liquid storage chamber 101.

[0113] Understandably, both the liquid inlet hole 1021 and the linear groove 1022 penetrate the sealing body 121 along the first direction Z.

[0114] The sealing structure 12 is elastic, and each linear groove 1022 extends to the inner peripheral wall of the inlet hole 1021, allowing the sealing structure 12 to deform at the linear groove 1022 to enlarge the inlet hole 1021. This allows for a smaller diameter of the inlet hole 1021 before deformation at the linear groove 1022, and the linear groove 1022 is linear, resulting in a smaller width. Consequently, the inlet groove 102 has a smaller diameter, preventing the aerosol-generating matrix in the storage chamber 101 from overflowing if the cover 20 is accidentally opened, thus reducing the risk of leakage.

[0115] In some embodiments, such as Figure 3 As shown, in the extension direction of the linear groove 1022, the size of the linear groove 1022 is larger than the size of the liquid inlet hole 1021. This helps to maximize the enlargement of the liquid inlet hole 1021 when the sealing structure 12 deforms at the linear groove 1022, thereby improving the replenishment efficiency of the aerosol generation matrix into the liquid storage chamber 101 through the liquid inlet hole 1021. Based on this, the design of the liquid inlet hole 1021 helps to reduce its diameter before deformation at the linear groove 1022, thereby further reducing the risk of leakage of the aerosol generation matrix through the liquid inlet groove 102.

[0116] In some embodiments, please refer to Figure 3 Furthermore, in conjunction with other accompanying drawings, multiple linear grooves 1022 are spaced apart and evenly distributed along the circumference of the liquid inlet hole 1021.

[0117] This design helps to maximize the enlargement of the inlet hole 1021 when the sealing structure 12 deforms at the linear groove 1022, thereby improving the replenishment efficiency of the aerosol generation matrix into the storage chamber 101 through the inlet hole 1021. Based on this, the design of the inlet hole 1021 helps to reduce its diameter before deformation at the linear groove 1022, further reducing the risk of leakage of the aerosol generation matrix through the inlet groove 102.

[0118] In some embodiments, please refer to Figure 3 And in conjunction with other accompanying drawings. There are two linear grooves 1022, which are arranged opposite to each other on the inner peripheral wall of the liquid inlet hole 1021.

[0119] This design has two advantages. First, when the sealing structure 12 deforms at the linear groove 1022, it helps to maximize the enlargement of the liquid inlet 1021, thereby improving the replenishment efficiency of the aerosol generating matrix into the storage chamber 101 through the liquid inlet 1021. Second, it can reduce the area of ​​the cross-section of the liquid inlet groove 102 perpendicular to the first direction Z, which helps to reduce the risk of leakage of the aerosol generating matrix through the liquid inlet groove 102.

[0120] In some embodiments, please refer to the following: Figure 2 and Figure 3 And in conjunction with other accompanying drawings. The housing 11 is provided with a main air passage 107 and an exhaust port 108. The main air passage 107, the liquid inlet 102, and the exhaust port 108 are spaced apart, and the exhaust port 108 communicates with the liquid storage chamber 101. The cover 20 includes a cover body 21 and a suction nozzle 22 provided on the cover body 21. The cover body 21 is movably connected to the housing 11 and can reciprocate relative to the housing 11 along the second direction X to open or close the liquid inlet 102. The sealing structure 12 is used to elastically abut against the cover body 21, and the suction nozzle 22 is used to communicate with the main air passage 107 when the cover body 21 closes the liquid inlet 102. One of the housing 11 and the cover body 21 is provided with a first sliding groove 201, and the other is fixed with a fixing member 31.

[0121] Understandably, the vent 108 is located at one end of the housing 11 along the first direction Z near the liquid inlet 102, and the main air passage 107 is exposed at one end of the housing 11 along the first direction Z near the liquid inlet 102.

[0122] The cover 21 is the main structure of the cover assembly 20. The cover 21 is movably connected to the end of the housing 11 along the first direction Z near the liquid inlet tank 102.

[0123] The housing 11 is also provided with an exhaust port 108 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 102, the gas in the liquid storage chamber 101 can be discharged through the exhaust port 108. This can improve the problem of leakage of the aerosol generation matrix in the liquid storage chamber 101 through the main air passage 107 caused by the pressure imbalance.

[0124] When the liquid inlet 102 is closed by the cover 21, the suction nozzle 22 is connected to the main air channel 107, so that the aerosol generated in the liquid storage structure can be discharged through the main air channel 107 and the suction nozzle 22 in sequence.

[0125] Please refer to the following: Figures 1 to 3 The aerosol generating device provided in this application embodiment 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.

[0126] Specifically, the atomizing core is located within the main air passage 107 of the liquid storage structure. The atomizing core refers to a structure used to generate heat when electricity is applied, thereby heating the aerosol-generating matrix and causing it to atomize into an aerosol.

[0127] The aerosol generating device provided in this application simplifies the assembly operation of the aerosol generating device and reduces the assembly difficulty by adopting the liquid storage structure involved in the above embodiments.

[0128] 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.
