[0041] This application provides a sealing component 10, a liquid storage device, and an aerosol generating device. The aerosol generating device is a device for generating aerosols, including but not limited to a heating element, a power supply component, a control unit, and an airflow channel. This device can generate aerosols by heating the aerosol-forming matrix stored in the liquid storage device. The heating element is the core component of the aerosol generating device. When powered by the power supply component, it generates heat through resistance heating and acts on the aerosol-forming matrix to generate aerosols. The power supply component provides power to the heating element and can be a built-in rechargeable battery (such as a lithium battery) or connected to an external power source via an external power interface. The power supply component typically includes circuit protection devices such as overcurrent protection and overvoltage protection to ensure that the aerosol generating device operates within a safe voltage and current range. The control unit is the part that performs overall regulation of the aerosol generating device. It can be a switching circuit or a control system containing a microprocessor, used to control the switching of the heating element, heating time, heating temperature, etc. The airflow channel guides airflow, with one end connected to the external environment and the other end connected to a mouthpiece for the user to inhale. When the aerosol generating device is working, air flows into the aerosol generating device through the airflow channel, and carries the heated aerosol to the nozzle for the user to inhale.

[0042] The liquid storage device can be installed inside the aerosol generator and positioned close to the nozzle. The aerosol generator, which stores liquid in the liquid storage device, can deliver the liquid to the heating element through a liquid guiding component with a conveying function.

[0043] The aforementioned liquid guiding component can be supported by a porous material for transporting aerosols to form a matrix. Other heating elements, power supply components, control units, and airflow channels can all refer to existing structures in related technologies, and will not be described in detail in this application.

[0044] Generally, the shape and size of the liquid storage device used to adapt to the aerosol generating device vary depending on the model and size of the device. When the liquid storage device is larger, the required sealing edge size is also larger, increasing the difficulty of sealing. Furthermore, larger liquid storage devices are more prone to deformation under external forces (such as bumps during transportation and external compression), making the sealing structure more susceptible to damage and leading to aerosol matrix leakage.

[0045] In order to overcome the above problems, improve the sealing effect of the liquid storage device, and improve the user experience of the corresponding aerosol generating device, this application provides a sealing member 10 and a liquid storage device having the sealing member 10.

[0046] Figure 1 This is a schematic diagram of the structure of the host sealing component 10 provided in the embodiments of this application. Figure 2 for Figure 1 A cross-sectional structural diagram. Figure 3 for Figure 1 The bottom view, Figure 4 This is a structural schematic diagram of the structural reinforcement 2 in the sealing member 10 provided in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of the sealing member 1 in the sealing member 10 provided in the embodiments of this application. Figure 6 This is an exploded structural diagram of the sealing member 10 provided in the embodiments of this application.

[0047] The aforementioned sealing member 10 is used to cooperate with the liquid storage tank to form a liquid storage device for storing the aerosol-forming matrix. Under the action of the sealing member 10, the pressure resistance of the liquid storage device can be improved, and its overall structural strength can also be improved.

[0048] The liquid storage device equipped with the above-mentioned sealing member 10 has superior sealing performance.

[0049] Please see Figure 1 and Figure 2The sealing component 10 includes two parts: a sealing element 1 and a structural reinforcement 2. The sealing element 1 has an installation groove 101 along its circumference, and the structural reinforcement 2 can be installed on the sealing element 1 through the installation groove 101.

[0050] The sealing member 10 provided in this application embodiment can reinforce the structure of the sealing member 1 through the structural reinforcement member 2 and enhance the circumferential support capacity of the sealing member 1, thereby effectively improving the overall support strength of the sealing member 10. This helps to improve the problem of insufficient support strength of the sealing member 10 due to its large size, and improves the strength and deformation resistance of the sealing member 1 without affecting its sealing effect.

[0051] It should be noted that the aforementioned sealing element 1 can be made of a material with good elastic deformation capability, such as silicone or rubber; correspondingly, the structural reinforcement 2 is made of a rigid material. The materials used to prepare the structural reinforcement 2 include at least one or more of the following: steel, aluminum, and rigid plastic.

[0052] After the structural reinforcement 2 is installed on the seal 1 through the mounting groove 101, the structural reinforcement 2 can provide better support for the seal 1 through the mounting groove 101, especially in the circumferential direction of the seal 1. The structural reinforcement 2 can effectively overcome the defects of the seal 1 caused by insufficient strength or excessive size, and can effectively improve the support strength of the structural reinforcement 2 without affecting the sealing performance of the seal 1.

[0053] Please see Figure 2 and Figure 4 The aforementioned structural reinforcement 2 includes a connected support component 21 and a reinforcing component 22, wherein the support component 21 and the reinforcing component 22 are integrally formed, and the support component 21 can be formed by folding the edge of the reinforcing component 22 toward the same side.

[0054] Specifically, the reinforcing component 22 is a plate-like structure, and at least part of its side edges can be folded toward the same side to form a support component 21. The support component 21 has a first end 211 and a second end 212, wherein the first end 211 is used to connect with the side edge of the reinforcing component 22, and the second end 212 (i.e., the free end of the support component 21) is used to be inserted into the mounting groove 101.

[0055] Please see Figure 2 When the structural reinforcement 2 is connected to the seal 1, the second end 212 can be attached to or abut against the bottom wall 102 of the mounting groove 101 formed on the seal 1, at which time at least part of the support assembly 21 is inserted into the mounting groove 101.

[0056] The aforementioned plate-shaped reinforcing component 22 can provide a certain degree of reinforcement to the seal 1 as a whole, ensuring that the seal 1 can maintain its original shape to a certain extent when subjected to external impact, compression, or other forces, thereby better fitting in the assembly position and reducing the possibility of seal failure due to deformation of the seal 1. The support component 21 inserted in the mounting groove 101 can provide a certain strength and good resistance to deformation to the outer peripheral sidewall of the seal 1, effectively improving the overall stability of the seal 1, so that the seal 1 can always maintain a tight fit with the relevant mating structure (such as the inner wall of the liquid storage tank) in the axial direction, ensuring that the seal 1 can always maintain a better sealing state, and further reducing the possibility of the seal 1 failing to seal properly.

[0057] In addition, the aforementioned reinforcing component 22 can also enhance the sealing element 1's ability to withstand assembly pressure. When the reinforcing component 22 is installed inside the liquid storage tank, it can effectively improve the overall strength of the liquid storage device.

[0058] In some embodiments, the number of mounting grooves 101 can be multiple and arranged at intervals along the circumference of the seal 1. In this case, the structural reinforcement 2 can be inserted into all of the mounting grooves 101 to support and reinforce the seal 1 at different circumferential positions.

[0059] In other similar embodiments, the number of the above-mentioned mounting groove 101 can be one and it is an annular groove structure arranged along the circumference of the seal 1. In this case, the above-mentioned structural reinforcement 2 can be inserted into the annular groove and support and reinforce each position of the annular groove.

[0060] For details, please refer to Figure 3 At this time, the mounting groove 101 opened on the seal 1 is an annular groove, and correspondingly, the support component 21 is an annular structure provided on one side of the thickness direction of the reinforcing component 22, and the support component 21 and the mounting groove 101 fit together perfectly.

[0061] Please see Figures 4-6 The sealing element 1 includes a sealing body 11.

[0062] The sealing body 11 has a first sidewall 111 and a second sidewall 112 in the thickness direction. A portion of the surface of the second sidewall 112 is recessed to form a mounting groove 101. A sealing ring 113 protrudes from a portion of the circumferential outer sidewall of the sealing body 11. The minimum distance between the structural reinforcement 2 inserted into the mounting groove 101 and the first sidewall 111 is a first distance, and the minimum distance between the sealing ring 113 and the first sidewall 111 is a second distance. The first distance is not greater than the second distance. Please refer to [link / reference]. Figure 2 .

[0063] Since the structural reinforcement 2 inserted in the mounting groove 101 is in contact with the bottom wall 102 of the mounting groove 101, the aforementioned first distance can also be regarded as the distance between the bottom wall 102 of the mounting groove 101 and the first side wall 111.

[0064] Since the first distance is no greater than the second distance, when the sealing component 10 is assembled with the liquid storage tank, the structural reinforcement 2 assembled in the mounting groove 101 can always provide outward support to the sealing ring 113, so that the sealing ring 113 can always keep in contact with the inner wall of the liquid storage tank and generate extrusion deformation under the action of the structural reinforcement 2. This makes the sealing ring 113 and the inner wall of the liquid storage tank keep tightly attached and form an annular sealing band with a better sealing effect, so as to avoid the problem of poor sealing that may occur, effectively improve the sealing effect of the sealing component 1, and reduce the possibility of leakage of the aerosol matrix through the assembly gap between the sealing component 1 and the liquid storage tank.

[0065] To further improve the sealing effect of the seal 1, in this embodiment, the number of the sealing protrusions 113 is two, and they are arranged at intervals along the thickness direction of the seal 1. Please refer to [link to relevant documentation]. Figure 5 .

[0066] In other similar embodiments, the number of the aforementioned sealing protrusions 113 may be one, three, or even more. Multiple sealing protrusions 113 are arranged sequentially at intervals along the thickness direction of the seal 1.

[0067] Please see Figure 5 In addition to the sealing body 11, the sealing element 1 also includes an assembly ring 12, which is integrally formed with the sealing body 11.

[0068] The seal 1 can be installed into the aerosol generating device via the assembly ring 12 and sealed to its internal components. In this case, the seal 1 is sealed to the inner wall of the storage tank via the sealing protrusion 113. Of course, in other similar embodiments, the seal 1 can also be sealed to the storage tank via the assembly ring 12 and sealed to the internal components of the aerosol generating device via the sealing protrusion 113.

[0069] The assembly ring 12 is an annular structure that extends along the thickness direction of the seal 1 in a direction away from the first sidewall 111.

[0070] Please see Figure 5 The aforementioned sealing element 1 is also provided with a vent hole 114 and a functional protrusion 115, etc.

[0071] Specifically, the sealing body 11 has a vent hole 114, which penetrates and connects the first sidewall 111 and the second sidewall 112. The vent hole 114 is used to allow airflow to pass through.

[0072] To avoid structural reinforcement 2 affecting vent 114, please refer to... Figure 4 and Figure 6 The aforementioned structural reinforcement 2 has an avoidance hole 201.

[0073] In the thickness direction of the seal 1, the orthographic projection of the vent 114 lies within the orthographic projection range of the clearance hole 201. At this time, the relevant airflow can flow from the clearance hole 201 to the vent 114.

[0074] Specifically, the functional protrusion 115 located on the sealing body 11 is formed by a protrusion of a portion of the surface of the second sidewall 112. In the thickness direction of the seal 1, the orthographic projection of the functional protrusion 115 is located within the orthographic projection range of the clearance hole 201.

[0075] The number of the aforementioned functional bumps 115 is multiple and their functions are different. For example, the functional bumps 115 can be used to install and fix circuit boards, or to install and fix liquid guiding components, or to connect heating elements, etc.

[0076] Depending on their function, the functional protrusion 115 can be set in various different shapes and positions. It is only necessary to ensure that the functional protrusion 115 does not affect the installation of the structural reinforcement 2 on the seal 1.

[0077] It is understood that the sealing member 10 provided in this application embodiment can improve the strength of the sealing member 1 through the rigid structural reinforcement member 2, thereby giving the sealing member 1 better strength and support without affecting its sealing performance. When the sealing member 10 is used in conjunction with the liquid storage tank to form a liquid storage device, the sealing member 10 can better resist external forces and maintain its original shape and position, achieving a more secure and sealed fit with the liquid storage tank. This reduces the possibility of sealing failure and leakage in the liquid storage device, and helps to improve the assembly quality and sealing effect of the liquid storage device.

[0078] In a second aspect, embodiments of this application also provide a liquid storage device, including a liquid storage chamber and a sealing member 10 as described in any of the above claims, wherein the sealing member 10 is connected to the liquid storage chamber, and the liquid storage chamber is used to store an aerosol forming matrix.

[0079] Specifically, the liquid storage chamber is a hollow shell structure with one open end, which is used to store the aerosol forming matrix. The open end can be connected to the sealing component 10 to seal the liquid storage chamber.

[0080] In some embodiments, the liquid storage tank may be provided with a liquid absorption element, such as absorbent cotton. The aerosol forming matrix is ​​adsorbed in the liquid absorption element, which can better prevent leakage of the aerosol forming matrix.

[0081] In the liquid storage device provided in this application embodiment, by cooperating the liquid storage chamber with the sealing member 10, the storage and sealing effect of the liquid storage chamber on the aerosol forming matrix is ​​effectively improved, and the sealing performance of the liquid storage device is improved.

[0082] The descriptions of the various embodiments above tend to emphasize the differences between them. Similarities or commonalities can be referenced interchangeably, and for the sake of brevity, they will not be repeated here. The above descriptions are merely preferred embodiments of this application and are not intended to limit the application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
