Description

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0032] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0033] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0034] Please see Figure 1 and Figure 2 This application provides an aerosol generation device, including an aerosol generation apparatus A and a power supply device B; wherein, the power supply device B is mainly used to supply power to the aerosol generation apparatus A, so as to cause the aerosol generation apparatus A to heat the aerosol generation matrix stored inside the aerosol generation apparatus A, thereby generating a usable aerosol.

[0035] For example, the power supply device B can be a collection of circuit boards, battery cells and other related components (such as buttons, displays, indicator lights and other components that play an information interaction role). With the help of the power supply device B, all or part of the functions of the aerosol generating device can be supported, such as controlling the aerosol generating device A to start and stop heating the aerosol generating matrix, adjusting the heating power and working mode of the aerosol generating device A, and displaying the status information of the aerosol generating device.

[0036] In some embodiments, please refer to Figure 2Aerosol generating device A and power supply device B are two relatively independent functional units. They are assembled together using detachable methods such as snap-fit, magnetic attraction, and socketing to form an aerosol generating device. For example, power supply device B can be detachably located at the end away from the exhaust port of aerosol generating device A. By constructing the aerosol generating device as a modular combination structure, the device can be easily and flexibly assembled and disassembled to meet different needs. For example, by combining power supply device B with different aerosol generating devices A, power supply device B can be reused, which helps reduce operating costs.

[0037] In some embodiments, the power supply device B and the aerosol generating device A may also adopt an integrated structure. For example, the relevant components of the power supply device B and the relevant components of the aerosol generating device A can be structurally integrated through a device housing to form an integrated aerosol generating device. Further details will not be elaborated here.

[0038] It should be noted that the description of "aerosol generating matrix" in this document is only for the purpose of describing the aerosol generating device more clearly and in detail. The aerosol generating matrix is ​​not necessarily a component of the aerosol generating device; that is, the aerosol generating matrix can be a component of the aerosol generating device or a consumable used in the aerosol generating device. In other words, the aerosol generating matrix does not constitute a limitation on the aerosol generating device provided in the embodiments of this application.

[0039] Depending on the application scenario of the aerosol generation equipment, the aerosol generation matrix can be a liquid medium such as physiological saline, liquid pharmaceuticals, liquid extracts, or e-liquid. For example, typical components of an aerosol generation matrix include: polyols (such as triethylene glycol, 1,3-butanediol, and glycerol), esters of polyols (such as mono-, di-, or triacetic acid esters of glycerol), aliphatic esters of mono-, di-, or polycarboxylic acids (such as dimethyl dodecanoate and dimethyl tetradecanoate), nicotine, flavoring substances, etc.

[0040] The following section mainly introduces aerosol generating device A and its related structures.

[0041] It should be noted that, to illustrate the aerosol generating device A more clearly and in detail, this paper defines three mutually perpendicular directions based on the structure of aerosol generating device A: the first direction, the second direction, and the third direction. Please refer to [link / reference needed]. Figure 3 In a certain state of the aerosol generating device (such as when it is placed naturally on a table or when the user is holding it normally), the first direction refers to the up and down direction, and one of the second and third directions can refer to the left and right direction, and the other can refer to the front and back direction.

[0042] Please see Figures 3 to 8In some embodiments, the aerosol generating device A includes an atomizing component 100, a housing component 200, a liquid replenishment component 300, and other functional components as needed, which are described in detail below.

[0043] Please see Figure 5 , Figure 7 and Figure 8 The atomizing component 100 is mainly used to heat the aerosol generating matrix to generate usable aerosol. The atomizing component 100 has an independent liquid storage chamber 100a and an atomizing channel 100b. The atomizing channel 100b extends along a first direction and is disposed in the liquid storage chamber 100a, and the atomizing channel 100b communicates with the outside of the liquid storage chamber 100a or the outside of the atomizing component 100. The liquid storage chamber 100a is used to contain or store the aerosol generating matrix, and the atomizing channel 100b is used to provide a path for the generated aerosol to be discharged from the atomizing component 100 along with the airflow flowing through the atomizing channel 100b.

[0044] For example, please refer to Figure 5 and Figure 8 The atomizing assembly 100 includes a first housing 110, an air guide tube 120, and a heating element 130. A liquid storage chamber 100a is formed inside the first housing 110. The air guide tube 120 is disposed through the first housing 110 along a first direction, that is, the air guide tube 120 is equivalent to being disposed inside the liquid storage chamber 100a. The two opposite ends of the air guide tube 120 in the first direction extend out of the liquid storage chamber 100a, so that the tube space of the air guide tube 120 is used as an atomizing channel 100b. For ease of distinction and description, the two opposite ends of the air guide tube 120 or the atomizing channel 100b in the first direction are respectively defined as the air inlet end and the air outlet end of the atomizing channel 100b.

[0045] A heating element 130 is disposed within the air duct 120 and electrically connected to a power supply device B. The heating element 130 may include a heating body and a liquid guide (e.g., a porous material, fibrous material, or other material with capillary action). The air duct 120 has a liquid guide hole on its wall, which connects the atomization channel 100b to the liquid storage chamber 100a. The heating element 130 is disposed within the air duct 120 in a manner that covers or seals the liquid guide hole. Thus, the aerosol generating matrix in the liquid storage chamber 100a can enter the heating element 130 through the liquid guide hole, allowing the heating element 120 to generate aerosols by heating the aerosol generating matrix. The generated aerosols can then be discharged along with the airflow passing through the air duct 120 or the atomization channel 100b.

[0046] Please see Figures 4 to 7The housing assembly 200 primarily provides structural assembly space for the atomizing assembly 100 and the liquid replenishment assembly 300. An internal receiving chamber 200a is formed within the housing assembly 200a. The atomizing assembly 100 is housed within the receiving chamber 200a. An air intake chamber 200b is formed between the housing assembly 100 and the atomizing assembly 200, located on opposite sides of the atomizing assembly 100 in a third direction. The air intake end of the atomizing channel 100b communicates with the outside of the housing assembly 200 through the air intake chamber 200b. Simultaneously, an exhaust channel 200c is provided at one end of the housing assembly 200 in a first direction, connecting the exhaust end of the atomizing channel 100b to the outside of the housing assembly 200. Based on the sequential connection between the air intake chamber 200b, the atomizing channel 100b, and the exhaust channel 200c, a relatively complete airflow path is formed within the internal structure of the aerosol generating device.

[0047] For example, please refer to Figure 5 and Figure 7 The housing assembly 200 includes a second housing 210, which has housing sidewalls that form a receiving chamber 200a. The housing sidewalls include two first sidewalls 210a and two second sidewalls 210b. The two first sidewalls 210a are opposite each other in a second direction, and the two second sidewalls 210b are opposite each other in a third direction. When the atomizing assembly 100 is housed in the receiving chamber 200a, the first sidewalls 210a seal against the atomizing assembly 100 (specifically, the housing wall in the corresponding direction of the first housing 110), while the second sidewalls 210b are spaced apart from the atomizing assembly 100. Thus, a corresponding air intake chamber 200b is formed between the second sidewalls 210b and the atomizing assembly 100. Based on the relative arrangement of the two second sidewalls 210b, the formed air intake chamber 200b is located on both sides of the atomizing assembly 100 that are opposite each other in a third direction.

[0048] Please see Figure 3 and Figure 4 The replenishment component 300 is mainly used to replenish the aerosol generation matrix to the atomizing component 100, thereby supporting the improvement of the endurance of the aerosol generating device A or the aerosol generating equipment. The housing component 200 also has a mounting structure for installing the replenishment component 300. This mounting structure is located on opposite sides of the atomizing component 100 or the receiving chamber 200a in the second direction. That is, the housing component 200 has two mounting structures, each for installing one corresponding replenishment component 300. In other words, the number of replenishment components 300 can be set to two, and the two replenishment components 300 can be installed on the housing component 200 through a corresponding mounting structure, arranged on opposite sides of the atomizing component 100 in the second direction.

[0049] Correspondingly, the atomizing component 100 also has a liquid guiding structure for establishing a liquid path connection with the replenishing component 300. This liquid guiding structure is disposed on opposite sides of the atomizing component 100 in the second direction and connects to the liquid storage chamber 100a, so that the liquid guiding structure, the mounting structure, and the replenishing component 300 correspond one-to-one. When the replenishing component 300 is assembled into the housing component 200 through the mounting structure, the liquid guiding structure of the atomizing component 100 can be inserted into the interior of the replenishing component 300, realizing liquid path connection between the atomizing component 100 and the replenishing component 300. The aerosol generating matrix stored in the replenishing component 300 can enter the atomizing component 100 (specifically, into the liquid storage chamber 100a) through the liquid guiding structure, thereby replenishing the atomizing component 100 with the aerosol generating matrix.

[0050] For example, please refer to Figures 5 to 7 For each mounting structure, the mounting structure includes two first mounting arms 210c and two second mounting arms 210d; wherein, the two first mounting arms 210c are opposite to each other in a first direction, and the two ends of the first sidewall 210a opposite to each other in the first direction are respectively connected to a corresponding first mounting arm 210c; the two second mounting arms 210d are opposite to each other in a third direction, and the two ends of the first sidewall 210a opposite to each other in the third direction are respectively connected to a corresponding second mounting arm 210d.

[0051] Thus, based on the relative positional relationship between the first sidewall 210a, the first mounting arm 210c, and the second mounting arm 210d, the mounting structure is constructed as a cavity structure with an opening. For ease of distinction and description, the cavity space of the mounting structure is defined as a receiving space, which can also be understood as being formed by the first sidewall 210a, the first mounting arm 210c, and the second mounting arm 210d, and this receiving space is located on one side of the receiving chamber 200a in the second direction. The liquid replenishment component 300 can be housed and placed within this receiving space to achieve the structural combination of the liquid replenishment component 300 and the housing component 200.

[0052] For example, please refer to Figure 4 The replenishment assembly 300 includes a liquid storage container 310 and a seal 320 that can be punctured by the liquid guiding structure of the atomizing assembly 100; wherein, the liquid storage container 310 has a replenishment port that communicates the interior and exterior of the liquid storage container 310, and the seal 320 is disposed at the replenishment port to seal and close the replenishment port.

[0053] For example, the seal 320 can be set inside the liquid storage container 310 and seal the liquid filling port. This not only helps to make the outline of the liquid storage container 310 more flat and regular, so as to improve the utilization rate of the structural space of the liquid storage container 310 and increase the capacity of the liquid storage container 310, but also avoids the seal 320 from falling off or being damaged due to external factors, effectively improving the sealing performance of the liquid filling component 300 itself.

[0054] Of course, the seal 320 can also be inserted into the liquid inlet 310 or exposed in the liquid inlet 310 in the form of a sealed cover, as long as the purpose is to achieve the purpose of sealing the liquid inlet 310, which will not be elaborated here.

[0055] Based on the structure of the replenishment component 300, the liquid guiding structure of the atomizing component 100 can be configured to pierce the seal 320 and extend into the liquid storage container 310; for example, please refer to... Figure 4 as well as Figures 6 to 8 The fluid guiding structure includes a puncture tube 140, which protrudes from the surface of the first housing 110 in the second direction and communicates with the fluid storage chamber 100a. The first sidewall 210a of the second housing 210 is connected to a window that provides a path for fluid communication between the atomizing assembly 100 and the replenishment assembly 300. That is, when the atomizing assembly 100 is housed and installed in the receiving chamber 200a, the puncture tube 140 extends out of the receiving chamber 200a through the connecting window and enters the receiving space.

[0056] Regarding the replenishment component 300, it can be detachably installed on the mounting structure, such as by snap-fit, magnetic attraction, or insert, thereby giving the replenishment component 300 the ability to switch between different states. For example, the replenishment component 300 has a first state and a second state. In the first state, the replenishment component 300 is separated from the housing component 100, and the sealing member 320 seals the replenishment port, allowing the replenishment component 300 to be transported, carried, or stored independently. In the second state, the replenishment component 300 is installed on the mounting structure (e.g., housed within a housing space). In this state, the puncture tube 140 punctures and passes through the sealing member 320 to extend into the liquid storage container 310, thereby connecting the internal space of the liquid storage container 310 with the liquid storage chamber 100a through the puncture tube 140, so that the replenishment component 300 can replenish the aerosol generation matrix to the atomizing component 100.

[0057] In summary, firstly, utilizing the structural interlayer space between the atomizing component 100 and the housing component 200 in the third direction as the air intake chamber 200b eliminates the need for an additional air intake channel for the atomizing component 100 within the housing component 200, thus reducing the structural complexity of the aerosol generating device A. Secondly, by placing the mounting structure (or the liquid replenishment component 300) on opposite sides of the atomizing component 100 in the second direction, the mounting structure (or liquid replenishment component 300) and the air intake chamber 200b are staggered and distributed on different sides of the atomizing component 100, thereby fully utilizing the structural space of the housing component 200 or the aerosol generating device A, enhancing the overall compactness and stability of the aerosol generating device A. Thirdly, regarding the air path formed by the connection of the air intake chamber 200b, the atomizing channel 100b, and the exhaust channel 100c, the intake of air from opposite sides of the aerosol generating device A via the two air intake chambers 200b facilitates smooth airflow, thereby improving the vaping experience.

[0058] Secondly, based on the cooperation of the two liquid replenishment components 300 and the atomizing component 100, it is equivalent to giving the aerosol generating device A three relatively independent aerosol generating matrix storage units. This can effectively increase the amount of aerosol generating matrix carried in the aerosol generating device A, thereby improving the endurance of the aerosol generating device A. For example, the capacity of the liquid storage container 310 can be set to 10ML, and the capacity of the liquid storage chamber 100a can be set to 2ML. In this way, when the two liquid replenishment components 300 are assembled in the shell component 200, it is equivalent to making the aerosol generating device A have a total storage capacity of 2+10+10.

[0059] Thirdly, based on the detachable connection between the replenishment component 300 and the housing component 200, not only can the replenishment component 300 be manufactured, transported, carried, and stored independently, but the aerosol generating device A can also be flexibly assembled or disassembled as needed. For example, by replacing the replenishment component 300 with one that stores different aerosol generating matrices, the aerosol generating device A can provide different types or flavors of aerosols. Furthermore, since the atomizing component 100 itself has the ability to store aerosol generating matrices, the aerosol generating device A can also be used normally without the replenishment component 300, thereby meeting different user needs.

[0060] Fourth, based on the staggered arrangement of the two air inlet chambers 200b and the two liquid replenishment components 300 (or two mounting structures), the aerosol generating device A can be constructed into a flat structure; for example, the overall outline dimensions of the aerosol generating device A can be set such that the dimension in the second direction is greater than the dimension in the third direction. This not only allows for more full and rational use of the structural space of the relevant components, but also makes the structure of the aerosol generating device A more compact and stable, facilitating user handling and storage.

[0061] It should be noted that in some embodiments, the liquid replenishment component 300 may not be a component of the aerosol generating device A, but rather an independent functional unit used in conjunction with the aerosol generating device A.

[0062] For example, in some scenarios, the endurance of the aerosol generating device A is enhanced by placing the replenishment component 300 inside the mounting structure and replenishing the aerosol generating matrix to the atomizing component 100. In other scenarios, after removing the replenishment component 300 from the mounting structure, the opening of the mounting structure is sealed, allowing the aerosol generating device A to maintain a relatively complete structural form. In this case, the aerosol generating device A can be used independently of the replenishment component 300 and can be used normally based on the presence of the atomizing component 100.

[0063] In some embodiments, please refer to Figures 5 to 7 The housing assembly 200 also includes an air inlet 200d, which is located on opposite sides of the exhaust end of the exhaust channel 200c or the atomizing channel 100b in a third-direction direction. The air inlet 200d connects the intake chamber 200b to the outside of the housing assembly 200, allowing external airflow to enter the intake chamber 200b through the air inlet 200d, thus forming a complete airflow path with the atomizing channel 100b and the exhaust channel 200c. For example, the second sidewall 210b has a plurality of air inlets 200d extending through its upper end in the first direction.

[0064] Thus, by positioning the air inlet 200d on the side away from the air inlet end of the atomizing channel 100b, the air inlet 200d and the air inlet end of the atomizing channel 100b are located at different positions on the atomizing assembly 100 or the aerosol generating device A. This effectively extends the length of the air inlet chamber 200b in the first direction, or increases the distance between the air inlet 200d and the air inlet end of the atomizing channel 100b. This effectively prevents condensate or aerosol generating matrix from leaking directly from the air inlet chamber 200b. Simultaneously, the air inlet 200d is positioned at the top of the housing assembly 100 in the first direction, which adapts to the user's grip habits and prevents the user's palm from obstructing the air inlet 200d when holding the aerosol generating device A, thus affecting its use.

[0065] It should be noted that, Figure 5 The bold dashed line with a single arrowhead indicates the approximate path of the airflow.

[0066] As mentioned above, in some embodiments, housing assembly 200 includes a second housing 210, see [link to relevant documentation]. Figures 4 to 7 The second housing 210 includes a housing portion 211, a nozzle portion 212, and an end cap portion 213. The housing portion 211 has a shell wall including a first side wall 210a, a second side wall 210b, a first mounting arm 210c, and a second mounting arm 210d. In other words, a receiving chamber 200a is formed inside the housing portion 211, and the mounting structure is disposed on the housing portion 211. The nozzle portion 212 is formed at one end of the housing portion 211 in a first direction. For example, the nozzle portion 212 and the housing portion 211 are an integral structure, and the exhaust channel 200c passes through the nozzle portion 212 and communicates with the receiving chamber 200a. The other end of the housing portion 211 in the first direction has an opening communicating with the receiving chamber 200a, and the end cap portion 213 is fixed to the housing portion 211 in the form of sealing the opening of the housing portion 211. For example, the end cap portion 213 and the housing portion 211 can be connected by a detachable method such as snap-fit.

[0067] Thus, by utilizing the connection between the end cap 213 and the housing 211, the atomizing component 100 can be inserted into the housing 211 from the end of the housing 211 away from the mouthpiece 212, and then the end cap 213 can be used to encapsulate and fix the atomizing component 100 in the housing 211. This not only allows the air outlet of the atomizing channel 100b to be sealed and connected to the exhaust channel 200c, and forms an air inlet chamber 200b between the housing 211 and the atomizing component 100, but also helps to reduce the assembly difficulty of the atomizing component 100 and the housing component 200.

[0068] In some embodiments, please refer to Figure 5 and Figure 7 The end cap portion 213 has a liquid collection chamber 213a inside. When the end cap portion 213 is connected to the housing portion 211, the liquid collection chamber 213a is located on the side of the atomizing assembly 100 away from the nozzle portion 212 in the first direction, and the air inlet end of the atomizing channel 100b is connected to the air inlet chamber 200b through the liquid collection chamber 213a. At the same time, a third liquid suction member 220 is provided in the liquid collection chamber 213a. The third liquid suction member 220 can be made of a porous material, fibrous material, or other material with capillary force. For example, the third liquid suction member 220 can be porous ceramic, cotton fiber, metal fiber, non-woven fabric, or a combination of one or more of the above materials.

[0069] In this way, liquids from the atomization channel 100b, such as condensate and aerosol generation matrix that may leak from the atomization channel 100b, can be collected using the liquid collection chamber 213a. These liquids are then adsorbed by the third liquid suction element 220 and stored in the liquid collection chamber 213a. This effectively prevents liquids in the atomization channel 100b from leaking into the air intake chamber 200b or from leaking through the air intake chamber 200b to the outside of the aerosol generation device A, thus avoiding pollution and affecting the user experience.

[0070] In some embodiments, please refer to Figure 7 The end cap portion 213 also has an expansion chamber 213b that communicates with the liquid collection chamber 213a. The expansion chamber 213b is located on opposite sides of the liquid collection chamber 213a in the second direction. The expansion chamber 213b is provided with a fourth liquid suction member 230. The fourth liquid suction member 230 can be made of the same material as the third liquid suction member 220, and the fourth liquid suction member 230 is connected to the third liquid suction member 220. For example, the fourth liquid suction member 230 is in contact with the third liquid suction member 220 or is an integral structure.

[0071] By utilizing the combination of the expansion chamber 213b and the liquid collection chamber 213a, the volume of the end cap 213 can be effectively increased, providing structural support for placing large-sized liquid suction components. This enables the collection, adsorption, and storage of large amounts of liquid, making it less prone to leakage after long-term use of the aerosol generating device A.

[0072] As mentioned above, in some embodiments, the atomizing assembly 100 includes a first housing 110 and an air guide tube 120; wherein, the first housing 110 may be assembled from multiple components. For details, please refer to... Figure 8 and combined Figure 5 The first housing 110 includes a tube body 111 and a sealing portion 112. The tube body 111 has two opposite ports in a first direction, and the sealing portion 112 seals and closes the ports of the tube body 111. For example, the sealing portion 112 may include an elastic material such as silicone. The sealing portion 112 is at least partially inserted into the ports of the tube body 111, thereby sealing the openings of the tube body 111. The gas guide tube 120 is located inside the tube body 111, and its two opposite ends in the first direction pass through the sealing portion 112, thereby forming a liquid storage chamber 100a between the gas guide tube 120, the tube body 111, and the sealing portion 112.

[0073] With the atomizing component 100 assembled in the receiving chamber 200a, the sealing part 112 can seal against the housing component 200. While stabilizing the tube part 111 and the like in the receiving chamber 200a, an air intake chamber 200b is formed between the tube part 111 and the housing component 200, and a sealed connection is achieved between the exhaust channel 200c and the atomizing channel 100b.

[0074] For example, when the atomizing component 100 is inserted into the housing portion 211 through the opening of the housing portion 211, the sealing portion 112 located at one end of the tube portion 111 can seal against the end of the housing portion 211 away from its opening or the part of the housing portion 211 that is connected to the mouthpiece portion 212, while the sealing portion 112 located at the other end of the tube portion 111 can seal against the side wall of the opening end of the housing portion 211; in this way, the air inlet chamber 200b can be formed, and the air outlet end of the atomizing channel 100b can be sealed and connected to the exhaust channel 200c.

[0075] In some embodiments, please refer to Figure 5 and Figure 8 The atomizing assembly 100 also includes a first liquid suction member 150, which is disposed in the liquid storage chamber 100a in such a way that it covers the communication between the atomizing channel 100b and the liquid storage chamber 100a; exemplaryly, the first liquid suction member 150 is sleeved on the outside of the air guide tube 120 and covers the liquid guide hole.

[0076] The first liquid-absorbing element 150 can be made of porous materials, fibrous materials, or other materials with capillary force. For example, the first liquid-absorbing element 150 can be porous ceramic, cotton fiber, metal fiber, non-woven fabric, or a combination of one or more of the above materials. By adsorbing and storing the aerosol generating matrix in the liquid storage chamber 100a by the first liquid-absorbing element 150, the aerosol generating matrix can be continuously guided into the heating element 130 to be heated by the heating element 130 to generate aerosol. On the other hand, it can also prevent the aerosol generating matrix from leaking out of the heating element 130 or the atomization channel 100b.

[0077] In some embodiments, please refer to Figure 5 , Figure 7 and Figure 8 The atomizing assembly 100 also includes a second liquid suction member 160, which is disposed on the side of the first housing 110 near the exhaust channel 200c. For example, the second liquid suction member 160 is clamped and fixed between the nozzle portion 212 and the corresponding sealing portion 112. The second liquid suction member 160 is mainly used to absorb and prevent the liquid in the exhaust channel 200c from entering the atomizing channel 100b.

[0078] More specifically, the second liquid-absorbing element 160 may be made of a porous material, fibrous material, or other material with capillary force; for example, the second liquid-absorbing element 160 may be a porous ceramic, cotton fiber, metal fiber, non-woven fabric, or a combination of one or more of the above materials.

[0079] As mentioned above, in some embodiments, the mounting structure adopts a cavity structure with an opening. In this case, the second mounting arm 210d can be omitted, or the second mounting arm 210d can be configured to partially cover the liquid replenishment component 300. This makes it easier for the user to assemble the liquid replenishment component 300 into the mounting structure by grasping the liquid replenishment component 330, or to pull it out of the mounting structure, thereby reducing the difficulty of assembling and disassembling the liquid replenishment component 300.

[0080] As mentioned above, in some embodiments, the mounting structure adopts a cavity structure with an opening. In this case, a first positioning structure 210e can be provided on the first mounting arm 210c or the second mounting arm 210d. Correspondingly, a second positioning structure (not shown in the figure) can be provided on the liquid replenishment component 300 (specifically, the liquid storage container 310). The first positioning structure 210e can be a snap-fit ​​structure protruding from the corresponding mounting arm, and the second positioning structure can be a slot structure provided on the surface of the liquid storage container 310.

[0081] By cooperating with the first positioning structure 210e and the second positioning structure, the liquid replenishment component 300 can be detachably and securely fixed within the receiving space, thereby ensuring the stability of the structural connection between the liquid replenishment component 300 and the housing component 200 and the atomizing component 100. Of course, the first positioning structure 210e and the second positioning structure can also be other structures or components, such as being detachably connected by magnetic attraction.

[0082] As mentioned above, in some embodiments, the liquid guiding structure of the atomizing component 100 includes a puncture tube 140, which may also include a protective element. For ease of description, the end of the puncture tube 140 that extends out of the receiving chamber 200a in the second direction is defined as the puncture end of the puncture tube 140. The puncture end may be configured as a sharp structure, for example, the port surface of the puncture end is an inclined bevel structure, which is beneficial for the puncture tube 140 to smoothly puncture the seal 320 and insert into the liquid storage container 310.

[0083] Regarding the protective component, it can be detachably fitted onto the outside of the puncture tube 140 to close or open the port of the puncture end. Specifically, when the fluid replenishment assembly 300 is in the first state, the protective component is fitted onto the outside of the puncture tube 140 and seals the port of the puncture end. This not only prevents the aerosol generation matrix in the fluid storage chamber 100a from leaking out of the puncture tube 140, but also provides structural protection for the puncture end of the puncture tube 140, preventing the puncture tube 140 from damaging other components or scratching the user.

[0084] By separating and disassembling the protective component from the puncture tube 140, support can be provided for the combined assembly of the liquid replenishment component 300, the housing component 200, and the atomizing component 100. That is, when the liquid replenishment component 300 is in the second state, the protective component is separated from the puncture tube 140, and at this time the puncture end of the puncture tube 140 pierces the seal 320 and extends into the liquid storage container 310.

[0085] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
