Description

Technical Field

[0001] This application belongs to the field of atomization technology, and more specifically, relates to an aerosol generating device and an electronic atomizer. 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] The aerosol generating device includes a liquid storage chamber and an atomizing component. The liquid storage chamber stores the aerosol generating matrix, and the atomizing component heats and atomizes the aerosol generating matrix to form aerosols. Before activation, the liquid storage chamber and the atomizing component are isolated from each other.

[0004] In some cases, when using an aerosol generator, it is generally necessary to activate the device first to connect the liquid storage chamber and the atomizing component. This allows the aerosol-generating matrix in the storage chamber to flow onto the atomizing component, where it is heated and atomized to form an aerosol. Then, the cap on the nozzle of the aerosol generator is removed. This allows the user to draw in the aerosol through the nozzle. Furthermore, the activation process requires following the instruction manual. Therefore, the pre-use procedures for aerosol generators are numerous, cumbersome, and time-consuming, reducing their ease of use.

[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

[0010] In some embodiments, the cap structure further includes an annular member disposed on the inner peripheral wall of the cap body, and a third limiting portion disposed at the end of the annular member away from the cap body.

[0011] In some embodiments, the protrusion is configured as an elastic structure.

[0012] In some embodiments, the cap structure is an elastic structure.

[0013] In some embodiments, the nozzle assembly includes: The first sleeve is fitted over the atomizing component; The nozzle is fitted over the first sleeve and is fixedly connected to the first sleeve; the housing is fitted over the nozzle, and the cap structure covers the nozzle; the first limiting part is used to limit the travel of the nozzle along the first direction; and the liquid storage chamber is located on the outer periphery of the first sleeve and the atomizing component.

[0014] In some embodiments, a first sealing ring abuts between the atomizing component and the nozzle component; in the initial state, the first sealing ring is located on the side of the inlet away from the cap structure; in the activated state, the first sealing ring is located on the side of the inlet closer to the cap structure.

[0015] In some embodiments, a second sealing ring abuts between the housing and the nozzle assembly.

[0016] In some embodiments, the inner peripheral wall of the housing is provided with a sliding groove extending along a first direction, a first limiting part is provided at one end of the sliding groove near the cap structure along the first direction, and a fourth limiting part is provided on the outer peripheral wall of the suction nozzle assembly. The fourth limiting part is inserted into the sliding groove and is used to slide along the sliding groove.

[0017] In some embodiments, there are multiple slides, which are spaced apart circumferentially.

[0018] In some embodiments, a fifth limiting portion is provided at one end of the slide away from the cap structure along the first direction. When the nozzle assembly is in the initial state, the fifth limiting portion is used to restrict the movement of the fourth limiting portion in the second direction; wherein the first direction and the second direction are opposite.

[0019] In some embodiments, the nozzle assembly is configured to move alternately along a first direction and a second direction to switch between an initial state and an active state; or, the nozzle assembly is provided with a locking portion, which engages with a first limiting portion when the nozzle assembly is in the active state to restrict the movement of the nozzle assembly in the first direction and restrict the movement of the nozzle assembly in the second direction.

In the activated state, the nozzle assembly opens the liquid inlet to connect the liquid inlet and the liquid storage chamber. Furthermore, a cap structure is used to move the nozzle assembly along the first direction under external force, and also to detach from the nozzle assembly along the first direction under external force when the nozzle assembly is in the activated state. Thus, when an external force is applied to the cap structure to move it along the first direction, the cap structure can first move the nozzle assembly relative to the housing and atomizing assembly along the first direction under the external force, switching the nozzle assembly from the initial state to the activated state, thereby connecting the atomizing chamber and the liquid inlet. Then, the cap structure moves relative to the nozzle assembly along the first direction under the external force to detach from the nozzle assembly. With this configuration, by applying an external force to the cap structure to move it along the first direction, the activation of the aerosol generating device and the disassembly of the cap structure can be achieved sequentially. In other words, before using the aerosol generator, the user only needs to apply external force to the cap structure to detach it from the nozzle assembly. This makes the operation steps before using the aerosol generator fewer, simpler, and faster, thus improving the ease of use of the aerosol generator.

[0025] The electronic atomizer provided in this application adopts the aerosol generating device involved in the above embodiments, which reduces the number of operation steps before using the electronic atomizer and makes it simple and quick, thereby improving the ease of use of the electronic atomizer.

[0038] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments: Please refer to the following: Figures 1 to 10 ,in, Figure 1 This is a three-dimensional structural diagram of the aerosol generating apparatus provided in some embodiments of this application in its initial state. Figure 2 This is a perspective view of the second sleeve 11 of the aerosol generating device provided in some embodiments of this application.

Figure 5 for Figure 3 A cross-sectional view of the aerosol generating device in the activated state. Figure 6 for Figure 5 Enlarged view at point C in the middle. Figure 7 for Figure 1 A sectional view along DD, Figure 8 for Figure 7 Enlarged view at point E in the middle. Figure 9 for Figure 7 A cross-sectional view of the aerosol generating device in the activated state. Figure 10 for Figure 9Enlarged view at point F. The aerosol generating device provided in this application includes an atomizing component 10, a housing 20, a nozzle assembly 30, and a cap structure 40. The atomizing component 10 has a liquid inlet 101. The housing 20 is sleeved on the atomizing component 10 and is fixedly connected to the atomizing component 10. A liquid storage chamber 201 is provided inside the housing 20, and a first limiting part 211 is provided on the housing 20. The nozzle assembly 30 is sleeved between the atomizing component 10 and the housing 20, and the nozzle assembly 30 protrudes from the housing 20 along a first direction Y1. The nozzle assembly 30 is configured to be movable relative to the housing 20 and the atomizing component 10 along the first direction Y1 to switch from an initial state to an active state. In the initial state, the nozzle assembly 30 covers the liquid inlet 101 to isolate the liquid inlet 101 from the liquid storage chamber 201. When activated, the nozzle assembly 30 opens the inlet 101 to connect the inlet 101 with the reservoir 201. The first limiting portion 211 restricts the travel of the nozzle assembly 30 along the first direction Y1. A cap structure 40 covers the portion of the nozzle assembly 30 that protrudes from the housing 20. The cap structure 40 is used to move the nozzle assembly 30 along the first direction Y1 under external force, and also to disengage from the nozzle assembly 30 along the first direction Y1 under external force when activated.

[0039] The atomizing component 10 refers to a component structure used to heat the aerosol generating matrix, thereby atomizing the aerosol generating matrix to form an aerosol. Understandably, the atomizing component 10 includes an atomizing chamber 102, which is used to heat and atomize the aerosol generating matrix to form an aerosol within the atomizing chamber 102. The atomizing chamber 102 is connected to the nozzle assembly 30, and the liquid inlet 101 is in liquid communication with the atomizing chamber 102. This liquid communication between the liquid inlet 101 and the atomizing chamber 102 means that liquid can be conducted between the liquid inlet 101 and the atomizing chamber 102. Specifically, the aerosol generating matrix in the liquid inlet 101 can be conducted into the atomizing chamber 102.

[0040] The liquid inlet 101 is a through hole provided on the atomizing assembly 10. Understandably, the liquid inlet 101 is located on the outer peripheral wall of the atomizing assembly 10.

[0041] The liquid storage chamber 201 is a space within the housing 20 used to store the aerosol generation matrix. As an example, such as... Figure 3 The liquid storage chamber 201 is located on the outer periphery of the nozzle assembly 30 and on the outer periphery of the atomizing assembly 10.

[0042] The nozzle assembly 30 is fitted between the atomizing assembly 10 and the housing 20, that is, the nozzle assembly 30 is fitted outside the atomizing assembly 10, and the housing 20 is fitted outside the nozzle assembly 30.

[0043] The first direction Y1 is the direction in which the nozzle assembly 30 protrudes from the housing 20, and it is a unidirectional direction. It can be understood that both the nozzle assembly 30 and the housing 20 have an axial direction, referred to simply as the axial direction. The first direction Y1 is approximately parallel to the axial direction.

[0044] Understandably, the nozzle assembly 30 in its initial state, such as Figure 3 and Figure 4 As shown, the nozzle assembly 30 is fitted over the portion of the atomizing assembly 10 with the liquid inlet 101 to cover the liquid inlet 101. In this way, the nozzle assembly 30 isolates the liquid storage chamber 201 from the liquid inlet 101, preventing the aerosol generating matrix in the liquid storage chamber 201 from being conducted into the atomizing assembly 10 through the liquid inlet 101. Therefore, by placing the nozzle assembly 30 in its initial state, the problem of leakage of the aerosol generating matrix caused by transportation or other operating conditions through the liquid inlet 101, atomizing chamber 102, and nozzle assembly 30 can be mitigated.

[0045] Understandably, when the nozzle assembly 30 is in the activated state, such as Figure 5 and Figure 6 As shown, the nozzle assembly 30 is not fitted over the portion of the atomizing assembly 10 with the liquid inlet 101, and thus does not cover the liquid inlet 101, leaving it exposed within the liquid storage chamber 201, which is connected to the liquid inlet 101. Alternatively, the nozzle assembly 30 is fitted over the portion of the atomizing assembly 10 with the liquid inlet 101, and the nozzle assembly 30 has a through hole directly opposite the liquid inlet 101, allowing the liquid inlet 101 to be exposed within the liquid storage chamber 201 through this through hole, thus connecting the liquid inlet 101 and the liquid storage chamber 201. In this way, the aerosol generating matrix within the liquid storage chamber 201 can be conducted to the atomizing assembly 10 through the liquid inlet 101, specifically to the atomizing chamber 102, where it is heated and atomized to form an aerosol. The aerosol can then be atomized through the nozzle assembly 30.

[0046] It should be further explained that the "activated state" refers to the state of the nozzle assembly 30 when the inlet 101 and the reservoir 201 are connected. Understandably, whether the nozzle assembly 30 fully opens the inlet 101 or only partially opens it, the reservoir 201 and the inlet 101 can be connected, and the nozzle assembly 30 can be considered to be in the activated state. After the nozzle assembly 30 moves along the first direction Y1 from its initial state until the reservoir 201 and the inlet 101 are connected, the stroke of the nozzle assembly 30 and the connected area of ​​the inlet 101 will vary, but all these variations can be considered as the nozzle assembly 30 being in the activated state.

[0047] It should also be noted that when the nozzle assembly 30 is in its initial state, the aerosol generating device can be considered to be in its initial state. When the nozzle assembly 30 is in its activated state, the aerosol generating device can be considered to be in its activated state.

[0048] The first limiting part 211 is part of the housing 20 and is used to limit the travel of the nozzle assembly 30 along the first direction Y1. In this way, after the nozzle assembly 30 moves along the first direction Y1 to switch from the initial state to the active state, the nozzle assembly 30 can be limited by the first limiting part 211, so that the nozzle assembly 30 cannot continue to move along the first direction Y1, thereby improving the problem of assembly failure of the aerosol generating device caused by the movement of the nozzle assembly 30.

[0049] As an example, the nozzle assembly 30 in its initial state, such as Figure 7 and Figure 8 As shown, the nozzle assembly 30 is not in contact with the first limiting part 211; specifically, the nozzle assembly 30 is not against the first limiting part 211 along the first direction Y1. In this case, the nozzle assembly 30 can move along the first direction Y1. When the nozzle assembly 30 is in the activated state, as... Figure 9 and Figure 10 As shown, the suction nozzle assembly 30 is limited and engaged with the first limiting part 211. Specifically, the suction nozzle assembly 30 abuts against the first limiting part 211 along the first direction Y1, so that the suction nozzle assembly 30 cannot continue to move along the first direction Y1.

[0050] The cap structure 40 refers to a structure used to cover the nozzle assembly 30. Specifically, the cap structure 40 is fitted over the portion of the nozzle assembly 30 that protrudes from the housing 20, and covers the end of the nozzle assembly 30 away from the housing 20 along the first direction Y1. In this way, the cap structure 40 can isolate the nozzle assembly 30 from the external environment, thereby achieving an isolation and protection effect for the nozzle assembly 30.

[0051] The cap structure 40 is used to drive the nozzle assembly 30 to move along the first direction Y1 under the action of an external force. This means that when the cap structure 40 is subjected to an external force moving along the first direction Y1, the cap structure 40 can drive the nozzle assembly 30 to move along the first direction Y1 as well. It can be understood that by applying a force moving along the first direction Y1 to the cap structure 40, the nozzle assembly 30 can move along the first direction Y1 under the action of the cap structure 40, thereby switching from the initial state to the active state.

[0052] The cap structure 40 is also used to detach from the nozzle assembly 30 along the first direction Y1 under the action of an external force when the nozzle assembly 30 is in the activated state. Specifically, when the nozzle assembly 30 is in the activated state, and the cap structure 40 is subjected to an external force moving along the first direction Y1, the cap structure 40 can detach from the nozzle 30 along the first direction Y1, thereby achieving the disassembly of the cap structure 40. Understandably, the cap structure 40 is detachably connected to the nozzle assembly 30. Understandably, when the nozzle assembly 30 is in the activated state, the nozzle assembly 30 and the first limiting part 211 engage in a limiting cooperation, preventing the nozzle assembly 30 from continuing to move along the first direction Y1. At this time, when the cap structure 40 is subjected to an external force that moves along the first direction Y1, the cap structure 40 tends to drive the nozzle assembly 30 to move along the first direction Y1. Based on the limiting cooperation between the nozzle assembly 30 and the first limiting part 211, the nozzle assembly 30 will not continue to move along the first direction Y1, but the cap structure 40 will move relative to the nozzle assembly 30 along the first direction Y1, so that the cap structure 40 can be removed from the nozzle assembly 30.

[0053] The aerosol generating device provided in this application embodiment is configured such that the nozzle assembly 30 is movable relative to the housing 20 and the atomizing assembly 10 along a first direction Y1 to switch from an initial state to an active state. In the active state, the nozzle assembly 30 opens the liquid inlet 101 to connect the liquid inlet 101 and the liquid storage chamber 201. Furthermore, the cap structure 40 is used to move the nozzle assembly 30 along the first direction Y1 under external force, and also to detach from the nozzle assembly 30 along the first direction Y1 under external force when the nozzle assembly 30 is in the active state. Thus, during the application of an external force along the first direction Y1 to the cap structure 40, the cap structure 40 can first move the nozzle assembly 30 relative to the housing 20 and the atomizing assembly 10 along the first direction Y1 under the external force, switching the nozzle assembly 30 from the initial state to the active state, thereby connecting the atomizing chamber 102 and the liquid inlet 101. Then, under the action of the external force, the cap structure 40 moves relative to the nozzle assembly 30 along the first direction Y1 to detach from the nozzle assembly 30. With this configuration, by applying an external force along the first direction Y1 to the cap structure 40, the activation of the aerosol generating device and the disassembly of the cap structure 40 can be achieved sequentially. That is, before using the aerosol generating device, the user only needs to apply an external force to the cap structure 40 to detach it from the nozzle assembly 30. This reduces the number of pre-use steps for the aerosol generating device, making it simple and quick, and improving its ease of use.

[0054] In some embodiments, please refer to the following: Figures 11 to 13 And in conjunction with other accompanying figures. Figure 11 for Figure 3 Enlarged view at point G in the middle. Figure 12This is a perspective view of the cap structure 40 of the aerosol generating apparatus provided in some embodiments of this application. Figure 13 This is a perspective view of the nozzle 31 of the aerosol generating device provided in some embodiments of this application. A second limiting portion 311 is provided on the outer peripheral wall of the nozzle assembly 30. The cap structure 40 includes a cap body 41 and a third limiting portion 42 provided on the inner peripheral wall of the cap body 41. The cap body 41 covers the nozzle assembly 30. One of the first limiting portion 211 and the second limiting portion 311 is a protrusion, and the other is a groove. The second limiting portion 311 and the third limiting portion 42 are in a concave-convex fit. The cap body 41 is used to drive the third limiting portion 42 to disengage from the second limiting portion 311 along the first direction Y1 under the action of external force.

[0055] The cap 41 is placed on the nozzle assembly 30, meaning that the cap 41 is placed on the part of the nozzle assembly 30 that protrudes from the housing 20 and covers the end of the nozzle assembly 30 away from the atomizing assembly 10 along the first direction Y1.

[0056] Among these, in some possible designs, such as Figures 11 to 13 As shown, the second limiting part 311 is a groove provided on the outer peripheral wall of the nozzle assembly 30, and the third limiting part 42 is a protrusion provided on the inner peripheral wall of the cap body 41. Alternatively, in some other possible designs, the second limiting part 311 is a protrusion provided on the outer peripheral wall of the nozzle assembly 30, and the third limiting part 42 is a groove provided on the inner peripheral wall of the cap body 41.

[0057] The second limiting part 311 and the third limiting part 42 are in a concave-convex fit, that is, the convex part and the groove are in a concave-convex fit, so that the cap body 41 and the nozzle assembly 30 can be limited in the first direction Y1. In this way, when the cap body 41 is subjected to an external force that moves along the first direction Y1, the limiting fit of the second limiting part 311 and the third limiting part 42 allows the nozzle assembly 30 to move along the first direction Y1 with the cap structure 40 under the driving action of the cap structure 40, so as to switch from the initial state to the active state.

[0058] The cap body 41 is used to drive the third limiting part 42 to disengage from the second limiting part 311 along the first direction Y1 under the action of external force. This means that when the cap body 41 is subjected to an external force that moves along the first direction Y1, the third limiting part 42 can move along the first direction Y1 with the cap body 41, thereby disengaging from the second limiting part 311 along the first direction Y1, and realizing the disassembly of the cap structure 40 and the suction nozzle assembly 30. Specifically, when the suction nozzle assembly 30 is in the activated state, when the cap body 41 is subjected to an external force that moves along the first direction Y1, based on the limiting cooperation between the suction nozzle assembly 30 and the first limiting part 211, the suction nozzle assembly 30 cannot move along the first direction Y1, and the third limiting part 42 disengages from the second limiting part 311 along the first direction Y1 with the cap body 41, so that the cap structure 40 is detached from the suction nozzle assembly 30.

[0059] By adopting the above technical solution, when the cap structure 40 is subjected to an external force moving along the first direction Y1, the aerosol generating device can be activated and the cap structure 40 can be disassembled in sequence.

[0060] In some embodiments, please refer to the following: Figures 11 to 13 And in conjunction with other accompanying drawings. The surface of the protrusion located within the groove is configured to extend in an arc shape along the first direction Y1, and the groove wall is configured to extend in an arc shape along the first direction Y1.

[0061] Specifically, the aerosol generating device is positioned on a cross-section parallel to the first direction Y1, such as... Figure 11 As shown, the line segment of the convex part located within the groove is an arc, and the groove wall is also an arc. As an example, such as... Figures 11 to 13 As shown, the surface of the protrusion located in the groove is configured as a semi-circular arc extending along the first direction Y1, and the groove wall is configured as a semi-circular arc along the first direction Y1.

[0062] Thus, when the nozzle assembly 30 is in the active state and the cap structure 40 is subjected to an external force moving along the first direction Y1, the protrusion easily disengages from the groove, thereby facilitating the third limiting part 42 to disengage from the second limiting part 311 along the first direction Y1 with the cap body 41, so that the cap structure 40 can be removed from the nozzle assembly 30. Understandably, it also facilitates the protrusion entering the groove, so that when the aerosol generating device is not needed, the cap structure 40 can continue to cover the nozzle assembly 30, thereby continuing to achieve the isolation and protection effect between the nozzle assembly 30 and the external environment.

[0063] This design facilitates the assembly and disassembly of the cap structure 40 and the nozzle assembly 30.

[0064] In some embodiments, please refer to the following: Figure 11 and Figure 12 In conjunction with other accompanying drawings, the cap structure 40 also includes an annular member 43, which is disposed on the inner peripheral wall of the cap body 41, and a third limiting part 42 is disposed at the end of the annular member 43 away from the cap body 41.

[0065] By setting the annular part 43, the distance between the inner peripheral wall of the cap body 41 and the third limiting part 42 can be increased, thereby reducing the contact area between the cap body 41 and the suction nozzle assembly 30, which facilitates the disassembly and assembly of the cap structure 40 and the suction nozzle assembly 30.

[0066] In some embodiments, the protrusion is configured as an elastic structure.

[0067] For example, the protrusion can be made into a component with elastic properties, such as a silicone structure or a rubber structure.

[0068] In this way, the protrusion can undergo elastic deformation, making it easy for the protrusion to enter and exit the groove, thereby facilitating the assembly and disassembly of the cap structure 40 and the nozzle assembly 30.

[0069] In some embodiments, the cap structure 40 is an elastic structure.

[0070] Understandably, the cap structure 40 as a whole can be configured as a component with elastic properties, such as a silicone structure or a rubber structure. Specifically, when the third limiting part 42 is a protrusion, the cap body 41, the ring part 43, and the third limiting part 42 are all configured as elastic structures, such as... Figure 11 As shown; when the third limiting part 42 is a groove, both the cap body 41 and the ring part 43 are set as elastic structures.

[0071] In this way, the cap structure 40 can undergo elastic deformation, which facilitates the engagement or disengagement of the third limiting part 42 and the second limiting part 311, thereby facilitating the assembly and disassembly of the cap structure 40 and the nozzle assembly 30.

[0072] In other embodiments, the cap structure 40 is an elastic structure. The cap structure 40 may not be provided with the third limiting part 42 and the annular part 43. Instead, the inner peripheral wall of the cap structure 40 abuts against the outer peripheral wall of the nozzle assembly 30, so that the cap structure 40 and the nozzle assembly 30 can be limited in the first direction Y1 by friction.

[0073] Thus, when the cap structure 40 is subjected to an external force, based on the friction between the cap structure 40 and the nozzle assembly 30, the nozzle assembly 30 can move along the first direction Y1 under the action of the cap structure 40, switching from the initial state to the active state. When the nozzle assembly 30 is in the active state, the nozzle assembly 30 and the first limiting part 211 are in a limiting engagement, and the nozzle assembly 30 cannot continue to move along the first direction Y1. At this time, if the cap structure 40 continues to be subjected to an external force, the cap structure 40 cannot drive the nozzle assembly 30 to continue to move along the first direction Y1. Instead, the cap structure 40 breaks free from the friction between the cap structure 40 and the nozzle assembly 30, and moves relative to the nozzle assembly 30, thereby allowing the cap structure 40 to be detached from the nozzle assembly 30.

[0074] In some embodiments, please refer to the following: Figure 3 , Figures 7 to 10 , Figure 13 And in conjunction with other accompanying drawings. The nozzle assembly 30 includes a first sleeve 32 and a nozzle 31. The first sleeve 32 is fitted over the atomizing assembly 10, and the nozzle 31 is fitted over the first sleeve 32, with the nozzle 31 fixedly connected to the first sleeve 32. A housing 20 is fitted over the nozzle 31, a cap structure 40 is fitted over the nozzle 31, a first limiting part 211 is used to limit the stroke of the nozzle 31 along the first direction Y1, and a liquid storage chamber 201 is located on the outer periphery of the first sleeve 32 and the atomizing assembly 10.

[0075] Understandably, the suction nozzle 31 protrudes from the housing 20 along the first direction Y1, and the cap structure 40 covers the portion of the suction nozzle 31 that protrudes from the housing 20. The second limiting part 311 is provided on the outer peripheral wall of the suction nozzle 31.

[0076] When the nozzle assembly 30 is in the active state, the first limiting part 211 is used to limit the movement of the nozzle 31 along the first direction Y1.

[0077] Understandably, the nozzle 31 is sealed at the end of the liquid storage chamber 201 away from the atomizing component 10 along the first direction Y1.

[0078] This reduces the diameter of the first sleeve 32, thereby increasing the capacity of the liquid storage chamber 201 and allowing the aerosol generating device to hold a larger amount of aerosol generating matrix.

[0079] In some embodiments, please refer to the following: Figure 9 and Figure 10 As shown, a third sealing ring 70 abuts between the first sleeve 32 and the suction nozzle 31, which can achieve a seal between the first sleeve 32 and the suction nozzle 31.

[0080] In some embodiments, please refer to the following: Figure 3 ,and Figure 14 , Figure 15 And in conjunction with other accompanying figures. Figure 14 This is a perspective view of the housing 20 of the aerosol generating apparatus provided in some embodiments of this application. Figure 15 for Figure 14 A cross-sectional view along HH. The housing 20 includes a first sleeve portion 21 and a second sleeve portion 22 disposed on the inner peripheral wall of the first sleeve portion 21. The second sleeve portion 22 has a fixing cavity 202. A portion of the atomizing assembly 10 is fixed in the fixing cavity 202, and another portion protrudes out of the second sleeve portion 22 along the first direction Y1 to extend into the first sleeve portion 21, such that the first sleeve portion 21 and the second sleeve portion 22 are together fitted over the atomizing assembly 10. A first sleeve 32 is fitted over the portion of the atomizing assembly 10 located inside the first sleeve portion, and the first sleeve portion 21 is fitted over the nozzle 31. A liquid storage cavity 201 is located on the outer periphery of the first sleeve 32 and the atomizing assembly 10, and is located between the nozzle 31 and the second sleeve portion 22. A first limiting portion 211 is disposed on the inner peripheral wall of the first sleeve portion 21.

[0081] Understandably, the size of the liquid storage chamber 201 will change when the nozzle assembly 30 moves along the first direction Y1. The actual capacity of the liquid storage chamber 201 is the capacity of the liquid storage chamber 201 in the initial state of the aerosol generating device.

[0082] This results in a larger space for the liquid storage chamber 201, which can accommodate a larger amount of aerosol generation matrix.

[0083] Based on this, when assembling the aerosol generating device, the atomizing core 12 can be assembled into the housing 20 first, and then the nozzle assembly 30 can be fitted over the atomizing assembly 10 and installed into the housing 20.

[0084] In some embodiments, please refer to the following: Figures 3 to 6 And in conjunction with other accompanying drawings. A first sealing ring 50 abuts between the atomizing assembly 10 and the nozzle assembly 30. In the initial state, the first sealing ring 50 is located on the side of the liquid inlet 101 away from the cap structure 40. In the activated state, the first sealing ring 50 is located on the side of the liquid inlet 101 closer to the cap structure 40.

[0085] The first sealing ring 50 is a structure such as a silicone ring or rubber ring with sealing performance.

[0086] Understandably, the first sealing ring 50 is fixed to and abuts against the inner peripheral wall of the nozzle assembly 30. Specifically, the first sealing ring 50 is fixed to and abuts against the inner peripheral wall of the first sleeve 32. Furthermore, the first sealing ring 50 abuts against the outer peripheral wall of the atomizing assembly 10. This achieves a seal between the nozzle assembly 30 and the atomizing assembly 10.

[0087] In its initial state, the nozzle assembly 30, such as Figure 3 and Figure 4 As shown, the first sealing ring 50 is located on the side of the liquid inlet 101 away from the cap structure 40, which achieves the sealing of the liquid inlet 101, thus further achieving the isolation between the liquid inlet 101 and the liquid storage chamber 201.

[0088] When the nozzle assembly 30 is in the active state, such as Figure 5 and Figure 6 As shown, the first sealing ring 50 is located on the side of the liquid inlet 101 close to the cap structure 40, so that the first sealing ring 50 does not seal the liquid inlet 101, thus allowing the liquid inlet 101 and the liquid storage chamber 201 to communicate.

[0089] The second sealing ring 60 is abutted between the atomizing component 10 and the nozzle assembly 30, so that the second sealing ring 60 can seal the movement gap between the atomizing component 10 and the nozzle assembly 30, which can improve the problem of leakage of aerosol generation matrix.

[0090] In some embodiments, please refer to the following: Figures 7 to 10 And in conjunction with other accompanying drawings, a second sealing ring 60 abuts between the housing 20 and the nozzle assembly 30.

[0091] The second sealing ring 60 is a structure with sealing properties such as a silicone ring or a rubber ring.

[0092] Understandably, the second sealing ring 60 abuts against the inner peripheral wall of the housing 20, specifically against the inner peripheral wall of the first sleeve portion 21. The second sealing ring 60 abuts against the outer peripheral wall of the nozzle assembly 30, specifically against the outer peripheral wall of the nozzle 31. Wherein, as Figures 7 to 10 As shown, the second sealing ring 60 can be fixed to the nozzle assembly 30, specifically to the nozzle 31; or, the second sealing ring 60 can also be fixed to the housing 20.

[0093] By abutting the second sealing ring 60 between the housing 20 and the nozzle assembly 30, the movement gap between the housing 20 and the nozzle assembly 30 can be sealed, thereby sealing the liquid storage chamber 201 and improving the problem of leakage of aerosol generation matrix.

[0094] In some embodiments, please refer to the following: Figures 7 to 10 In conjunction with other accompanying drawings, the inner peripheral wall of the housing 20 is provided with a sliding groove 203 extending along the first direction Y1. A first limiting part 211 is provided at one end of the sliding groove 203 along the first direction Y1 near the cap structure 40. A fourth limiting part 312 is provided on the outer peripheral wall of the suction nozzle assembly 30. The fourth limiting part 312 is inserted into the sliding groove 203 and is used to slide along the sliding groove 203.

[0095] Specifically, the fourth limiting part 312 is provided on the outer peripheral wall of the suction nozzle 31.

[0096] Specifically, the slide groove 203 is provided on the inner peripheral wall of the first sleeve portion 21.

[0097] Understandably, when the nozzle assembly 30 moves along the first direction Y1, the fourth limiting part 312 on the nozzle assembly 30 can slide along the slide groove 203 in the first direction Y1, which facilitates the nozzle assembly 30 to switch from the initial state to the active state.

[0098] The first limiting part 211 is provided at one end of the slide groove 203 along the first direction Y1 near the cap structure 40, so that when the nozzle assembly 30 is in the initial state, as Figure 7 and Figure 8 As shown, the fourth limiting part 312 and the first limiting part 211 are sequentially spaced along the first direction Y1. The fourth limiting part 312 does not abut against the first limiting part 211 along the first direction Y1, that is, there is no limiting engagement between the first limiting part 211 and the fourth limiting part 312. The fourth limiting part 312 can move along the first direction Y1, that is, the suction nozzle assembly 30 can move along the first direction Y1. When the suction nozzle assembly 30 is in the active state, as... Figure 9 and Figure 10As shown, the fourth limiting part 312 can abut against the first limiting part 211 along the first direction Y1, so that the fourth limiting part 312 cannot move along the first direction Y1, that is, the suction nozzle assembly 30 cannot continue to move along the first direction Y1. This configuration facilitates the first limiting part 211 to limit the suction nozzle assembly 30.

[0099] In other embodiments, the groove 203 may be provided on the outer peripheral wall of the suction nozzle assembly 30, and the first limiting part 211 may be slidably disposed in the groove 203.

[0100] In some embodiments, the number of slides 203 is multiple, and the multiple slides 203 are arranged at circumferential intervals.

[0101] This design ensures that the groove 203 is not an annular groove. Thus, when the second sealing ring 60 moves with the nozzle assembly 30 to the position of the groove 203, the second sealing ring 60 can still abut against the housing 20 and the nozzle assembly 30; specifically, the second sealing ring 60 abuts against the housing 20 at the position between two adjacent grooves 203. Therefore, the sealing effect between the nozzle assembly 30 and the housing 20 can still be guaranteed.

[0102] Specifically, in its initial state, the nozzle assembly 30, such as Figure 7 and Figure 8 As shown, the second sealing ring 60 is located at the position of the slide groove 203. The second sealing ring 60 can still abut against the housing 20 and the suction nozzle assembly 30. Specifically, the second sealing ring 60 abuts against the housing 20 at the position between two adjacent slide grooves 203.

[0103] In some embodiments, please refer to the following: Figures 7 to 10 And in conjunction with other accompanying drawings. A fifth limiting portion 212 is provided at the end of the slide 203 away from the cap structure 40 along the first direction Y1. In the initial state, the fifth limiting portion 212 restricts the movement of the fourth limiting portion 312 in the second direction Y2. The first direction Y1 and the second direction Y2 are opposite.

[0104] Understandably, the fifth limiting part 212 and the first limiting part 211 are arranged alternately along the first direction Y1.

[0105] Thus, when the nozzle assembly 30 is in its initial state, the fifth limiting part 212 can limit the fourth limiting part 312, thereby limiting the nozzle assembly 30 and preventing it from moving infinitely along the second direction Y2, which could cause the nozzle assembly 30 or other components to be subjected to compression and damage. Understandably, when assembling the aerosol generating device, the nozzle assembly 30 can be inserted into the housing 20 along the second direction Y2. When the fourth limiting part 312 abuts against the fifth limiting part 212 along the second direction Y2, it indicates that the nozzle assembly 30 is properly assembled.

[0106] In some embodiments, when the nozzle assembly 30 is in its initial state, the first sleeve 32 and the second sleeve portion 22 are spaced apart along the second direction Y2; or, the first sleeve 32 abuts against the second sleeve portion 22 along the second direction Y2.

[0107] In some embodiments, the nozzle assembly 30 is configured to move alternately along a first direction Y1 and a second direction Y2 to switch between an initial state and an active state. The first direction Y1 and the second direction Y2 are opposite.

[0108] Understandably, the nozzle assembly 30 is movable relative to the housing 20 and the atomizing assembly 10 along a first direction Y1, and also along a second direction Y2. When the nozzle assembly 30 moves along the first direction Y1, it can switch from an initial state to an active state. When the nozzle assembly 30 moves along the second direction Y2, it can switch from an active state to an initial state.

[0109] With this configuration, when the aerosol generating device is not in use, the nozzle assembly 30 can be moved relative to the housing 20 and the atomizing assembly 10 along the second direction Y2, switching the nozzle assembly 30 from the active state to the initial state, thus isolating the liquid inlet 101 and the liquid storage chamber 201 from each other. This improves the problem of leakage of the aerosol generating matrix in the liquid storage chamber 201 through the liquid inlet 101, the atomizing chamber 102, and the nozzle assembly 30 in sequence.

[0110] Understandably, after the nozzle assembly 30 moves along the second direction Y2 to switch from the active state to the initial state, the fourth limiting part 312 can abut against the fifth limiting part 212 along the second direction Y2 to limit the travel of the nozzle assembly 30 along the second direction Y2.

[0111] In other embodiments, the nozzle assembly 30 is provided with a locking portion. When the nozzle assembly 30 is in the activated state, the locking portion engages with the first limiting portion 211 to restrict the movement of the nozzle assembly 30 in the first direction Y1 and the second direction Y2. The first direction Y1 and the second direction Y2 are opposite.

[0112] The engaging portion can be a slot, and the first limiting portion 211 can be a buckle that engages with the slot. Alternatively, the engaging portion can be a buckle, and the first limiting portion 211 can be a slot that engages with the buckle.

[0113] Understandably, when the nozzle assembly 30 is in the active state, the locking part and the first limiting part 211 engage, preventing the nozzle assembly 30 from moving along the first direction Y1 or the second direction Y2. This allows the aerosol generating device to remain in the active state, preventing the nozzle assembly 30 from switching to its initial state during use and improving the ease of use of the aerosol generating device.

[0114] In some embodiments, please refer to the following: Figure 3 and Figure 7 And in conjunction with other accompanying drawings. In the initial state, the nozzle assembly 30 has its cap structure 40 abutting against the housing 20 along the second direction Y2. The first direction Y1 and the second direction Y2 are opposite.

[0115] Specifically, in the initial state, the nozzle assembly 30 has the cap 41 abutting against the first sleeve portion 21 along the second direction Y2.

[0116] By having the cap structure 40 abut against the housing 20 along the second direction Y2, the movement of the nozzle assembly 30 in the second direction Y2 can be limited. This mitigates the problem of accidental contact of the cap structure 40 causing the nozzle assembly 30 to move along the second direction Y2, potentially leading to damage to the nozzle assembly 30 or other components. It also mitigates the problem of over-assembly of the nozzle assembly 30 along the second direction Y2 during assembly of the cap structure 40 and the nozzle assembly 30 onto the housing 20, which could result in damage to the nozzle assembly 30 or other components.

[0117] In some embodiments, please refer to the following: Figure 3 , Figure 5 , Figure 7 and Figure 9 And in conjunction with other accompanying drawings. The atomizing assembly 10 includes a second sleeve 11 and an atomizing core 12. The second sleeve 11 is provided with a liquid inlet 101. The housing 20 is sleeved on the second sleeve 11 and is fixedly connected to the second sleeve 11. The nozzle assembly 30 is sleeved on the second sleeve 11. The atomizing core 12 is disposed inside the second sleeve 11.

[0118] The atomizing core 12 refers to the structure used to heat the aerosol generating matrix so that the aerosol generating matrix is ​​heated and atomized to form an aerosol. Specifically, the first sleeve portion 21 and the second sleeve portion 22 are together sleeved on the outside of the second sleeve 11, and the second sleeve portion 22 is fixedly connected to the second sleeve 11.

[0119] Specifically, the first sleeve 32 is fitted over the second sleeve 11, and the first sealing ring 50 abuts against the space between the first sleeve 32 and the second sleeve 11.

[0120] Understandably, an atomizing chamber 102 is formed inside the second sleeve 11, and the atomizing core 12 is disposed inside the atomizing chamber 102.

[0121] With this configuration, when the nozzle assembly 30 is in the active state, the aerosol generating matrix in the liquid storage chamber 201 can be conducted to the second sleeve 11 through the liquid inlet 101, and then to the atomizing core 12. The atomizing core 12 heats the aerosol generating matrix, so that the aerosol generating matrix is ​​heated and atomized to form an aerosol. The aerosol is then atomized through the nozzle assembly 30.

[0122] In some embodiments, please refer to the following: Figure 3 , Figure 5 , Figure 7 and Figure 9 And in conjunction with other accompanying drawings. The atomizing core 12 includes a liquid guiding component 122, a heating component 121, and a liquid storage component 123. The heating component 121 is disposed on the liquid guiding component 122, and the liquid storage component 123 is sleeved between the liquid guiding component 122 and the second sleeve 11.

[0123] The heating element 121 is configured to generate heat when energized, thereby heating the aerosol-generating matrix. The heating element 121 may be, but is not limited to, a heating mesh.

[0124] Liquid-guiding component 122 refers to a component with liquid-guiding properties, which may be, but is not limited to, liquid-guiding cotton.

[0125] The liquid storage component 123 refers to a component used to store the aerosol generation matrix, which may be, but is not limited to, liquid storage cotton.

[0126] Understandably, the liquid guiding component 122 and the liquid storage component 123 are arranged to form the atomizing chamber 102.

[0127] The liquid storage component 123 is sleeved on the liquid guiding component 122 and the second sleeve 11, which means that the liquid storage component 123 is sleeved on the liquid guiding component 122 and the second sleeve 11 is sleeved outside the liquid storage component 123.

[0128] Understandably, the liquid inlet 101 and the atomizing chamber 102 are in liquid communication, specifically, the liquid inlet 101 and the atomizing chamber 102 are connected by a liquid storage component 123 and a liquid guiding component 122. Specifically, the aerosol generating matrix can be conducted between the liquid inlet 101 and the atomizing chamber 102 through the liquid storage component 123 and the liquid guiding component 122.

[0129] Thus, when the nozzle assembly 30 is in the activated state, the aerosol generating matrix in the liquid storage chamber 201 can enter the liquid storage component 123 through the liquid inlet 101. The aerosol generating matrix in the liquid storage component 123 can be conducted to the heating element 121 through the conduction of the liquid guide 122. The heating element 121 heats and atomizes the aerosol generating matrix to form an aerosol.

[0130] By setting up a liquid storage device 123, the aerosol generation matrix can be stored inside the liquid storage device 123, which can improve the problem of leakage of the aerosol generation matrix as it passes through the atomization chamber 102 and the nozzle assembly 30 in sequence.

[0131] Please see Figure 1 The electronic atomizer provided in this application embodiment includes an aerosol generating device and a power supply device. The power supply device is mounted on the aerosol generating device and electrically connected to it. The aerosol generating device in this embodiment is the same as that in the above embodiments; please refer to the relevant descriptions of the aerosol generating devices in the above embodiments for details, which will not be repeated here.

[0132] Specifically, the power supply is mounted on the housing 20 and electrically connected to the atomizing assembly 10. Specifically, the power supply is electrically connected to the heating element 121.

[0133] The electronic atomizer provided in this application adopts the aerosol generating device involved in the above embodiments, which reduces the number of operation steps before using the electronic atomizer and makes it simple and quick, thereby improving the ease of use of the electronic atomizer.

[0134] 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.
