The liquid storage compartment is used for storing atomized liquid, and the atomization core includes a heating element. The heating element can heat the atomized liquid entering the atomization core to form an aerosol.

[0004] To function properly, the atomization core needs to communicate not only with the liquid storage compartment but also with the air supply channel and the aerosol discharge channel. As a result, the atomized liquid entering the atomization core may leak from the air supply channel and discharge channel. To prevent liquid leakage, the related arts consider adding a sealing structure between the liquid storage compartment and the atomization core. Before the first use of the atomization device, the sealing structure can isolate the liquid storage compartment from the atomization core, thereby preventing liquid leakage.

DETAILED DESCRIPTION

[0032] The following detailed explanation of the present application is provided in conjunction with the drawings through specific embodiments. In different embodiments, similar components use related and similar reference numerals. In the following embodiments, many detailed descriptions are provided to better understand the present application. However, those skilled in the art can effortlessly recognize that some features may be omitted in different situations or replaced by other components, materials, or methods. In certain cases, some operations related to the present application are not shown or described in the specifications to prevent the core parts of the present application from being overwhelmed with descriptions. For those skilled in the art, detailed descriptions of these operations are not necessary, as they can fully understand the related operations based on the description in the specification and general technical knowledge in the field.

[0033] Additionally, the characteristics, operations, or features described in the specification can be combined in any appropriate way to form various embodiments. The steps or actions in the method description can also be reordered or adjusted in a way that is apparent to those skilled in the art. Thus, the various sequences in the specification and drawings are only intended to clearly describe a particular embodiment and do not imply that the sequence is mandatory unless otherwise stated that a particular sequence must be followed.

[0034] The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connected" or "coupled" as used in the present application include both direct and indirect connections or couplings unless otherwise specified.

[0035] In the present application, the device switch 350 of the atomization device can achieve linkage with the liquid supply switch 250 through a linkage structure. When the device switch 350 is in the closed state, the liquid supply switch 250, the circuit switch element 334, and the air intake port 346 of the air intake channel are all closed, which can prevent atomized liquid in the liquid storage compartment 211 from leaking through the liquid supply channel and the atomization core 230. At the same time, when the device switch 350 is open, it not only can activate the circuit of the atomization device but also can open the liquid supply switch 250 through the linkage structure and change the opening condition of the air intake port 346, thus realizing one-button operation through the device switch 350. This meets the normal usage requirements of the atomization device and avoids the need for multiple operations on the circuit, airflow, and liquid path, making it convenient to use.

[0036] An embodiment of the atomization device in the present application is as follows. To facilitate a clearer explanation of the specific implementation of the present application, the following description refers to the orientations of up, down, left, right, front, and back as shown in Figure 1. Of course, this orientation limitation in the embodiment is only an example to clarify the positional relationship between various components and does not limit the specific implementation of the present application to this arrangement.

[0037] Please refer to Figure 1. In one embodiment, the atomization device includes a first cover body 110 and a second cover body 120, where the first cover body 110 and the second cover body 120 are respectively located on the front and rear sides of the device body, and the device body includes a first module 200 and a second module 300 that are connected together.

[0038] The first cover body 110 and the second cover body 120 serve as decorative components for aesthetic enhancement and as a protective shell. The first cover body 110 may be equipped with a screen for displaying information. Additionally, a lens cover plate 130 can be provided on the first cover body 110, with the screen located on the rear side of the lens cover plate 130. The lens cover plate 130 can have a reflective coating to form a semitransparent structure, which can block a portion of the screen's light, improve visual effects, and also have reflective properties for decorative purposes. It should be noted that in some other embodiments, the screen and the lens cover plate 130 can also be omitted.

[0039] In one embodiment, please refer to Figures 2 to 5. The first module 200 may be a liquid storage cup assembly, including a liquid storage cup 210, a liquid storage cup holder 220, an atomization core 230, filter cotton 240, and a liquid supply switch 250. The second module 300 may be a control module, including a bottom shell 310, a module holder 320, a circuit board assembly 330, an airflow unit 340, a device switch 350, and a linkage structure. The structure of the first module 200 and the second module 300 will be described separately below.

[0040] In the first module 200, the liquid storage cup 210 has a cavity, and the cavity forms a liquid storage compartment 211 for storing atomized liquid. The top surface of the liquid storage cup holder 220 is provided with an atomization core mounting hole 222 and a liquid supply switch hole 223. The atomization core mounting hole 222 is for embedding the atomization core 230 and can provide a mounting base for the atomization core 230. The atomization core mounting hole 222 is a through hole, and the bottom of the through hole is provided with a sealing plug 224, which has an airflow hole that can connect to the airflow unit 340 on the second module 300. The liquid supply switch hole 223 is used for installing the liquid supply switch 250 to achieve the closing and opening of the liquid supply channel. In the embodiment illustrated in Figure 2, the liquid supply switch hole 223 is also a through hole, allowing the liquid supply switch 250 to move up and down within the liquid supply switch hole 223. The liquid supply switch hole 223 can include a body communication hole 2231 and a guiding hole 2232, where the body communication hole 2231 is located at the upper part and the guiding hole 2232 is located at the lower part.

[0041] Please refer to Figures 3 to 7 and Figure 10. The liquid storage cup holder 220 is provided with a front-and-back penetrating intermediate layer 221, where the intermediate layer 221 is used to form the liquid supply chamber 270. The liquid supply chamber 270 also penetrates through the liquid supply switch hole 223 and the atomization core mounting hole 222, thereby allowing the liquid supply switch hole 223 to communicate with the liquid inlet 2311 on the atomization core 230. The portion of the liquid storage cup holder 220 located above the intermediate layer 221 forms an isolation structure, where the body communication hole 2231 is set on the isolation structure. The body communication hole 2231 is used to connect the liquid storage compartment 211 and the liquid supply chamber 270. The liquid supply channel includes the above-mentioned liquid supply chamber 270 and the body communication hole 2231.

[0042] Please refer to Figure 6. The liquid supply switch 250 includes a plug portion 251 for sealing the body communication hole 2231 and a rod portion 252 connected to the plug portion 251. The rod portion 252 is positioned in the guiding hole 2232, and the diameter of the rod portion 252 is smaller than that of the plug portion 251. When the liquid supply switch 250 is opened, the plug portion 251 disengages from the body communication hole 2231, and the rod portion 252 passes through the body communication hole 2231, forming a communication passage between the rod portion 252 and the wall of the body communication hole 2231. In some other embodiments, the liquid supply switch 250 can also be replaced with other structural forms that can achieve the closing and opening of the liquid supply channel. For example, the liquid supply switch hole 223 can be an equal diameter hole with the same diameter at both the upper and lower parts, and the liquid supply switch 250 can be a columnar structure with equal diameters at both the upper and lower parts.

[0043] In one embodiment, a sealing ring 253 is provided between the outer peripheral surface of the liquid supply switch 250 and the wall of the guiding hole 2232, where the sealing ring 253 is in interference fit with the outer peripheral surface of the liquid supply switch 250 and the wall of the guiding hole 2232, allowing the liquid supply switch 250 to be positioned within the guiding hole 2232 by means of frictional force. The sealing ring 253 can be arranged in two or more locations along the movement direction of the liquid supply switch 250, i.e., up and down, which helps ensure the stable operation of the liquid supply switch 250.

[0044] In some other embodiments, the liquid supply switch 250 can also be replaced with other structural forms. For example, the plug portion 251 of the liquid supply switch 250 can be positioned above the liquid supply switch hole 223, where the radial dimension of the plug portion 251 can be set greater than the radial dimension of the body communication hole 2231, thereby sealing the body communication hole 2231. In this case, a sealing fit can be achieved between the plug portion 251 and the top surface of the liquid storage cup holder 220. The liquid supply switch 250 can also be in the form of a valve sheet, which can press against the top surface of the liquid storage cup holder 220 using an elastic structure to seal the body communication hole 2231.

[0045] The top of the liquid storage cup holder 220 can be securely fitted with an elastic sealing member 260 made of an elastic material. In one embodiment, the elastic sealing member 260 includes a first layer sealing body 261, a second layer sealing body 262, and a connecting body 263, where the first layer sealing body 261 and the second layer sealing body 262 are arranged vertically spaced apart and interconnected by the connecting body 263, forming a single integral part for ease of assembly. The connecting body 263 can be located in any position of the elastic sealing member 260, for example, as shown in Figures 4, 5, and 10, where the connecting body 263 can be positioned on the right side of the elastic sealing member 260. The first layer sealing body 261 is capable of forming a seal between the inner wall of the liquid storage cup 210 and the top of the liquid storage cup holder 220, as well as forming a seal between the body communication hole 2231 and the liquid supply switch 250. The second layer sealing body 262 is located below the intermediate layer 221, creating a closed space between the intermediate layer 221 and the liquid storage compartment 211, which is the liquid supply chamber 270. In a specific embodiment, a sealing ring 253 can also be provided on the outer peripheral surface of the plug portion 251 of the liquid supply switch 250, forming a seal between the sealing ring 253 and the body communication hole 2231 by the sealing ring 253.

[0046] In a specific embodiment, please refer to Figures 2, 3, and 7. The atomization core 230 may include an outer cylinder 231, a liquid storage component 232, an inner sleeve 233, a liquid guiding component 234, and a heating element 235 laid out sequentially from the outside to the inside, where both the liquid storage component 232 and the liquid guiding component 234 can consist of porous liquid guiding cotton, which can utilize capillary action to absorb and transfer atomized liquid.

[0047] The outer cylinder 231 is provided with a liquid inlet 2311, where the liquid inlet 2311 allows atomized liquid to enter the atomization core 230, and is then sequentially transported through the liquid storage component 232 and the liquid guiding component 234 to the heating element 235, forming an aerosol under the heating action of the heating element 235. The liquid inlet 2311 can be a through hole positioned on the outer peripheral surface of the lower end of the outer cylinder 231. The shape, quantity, and location of the through hole can be set as needed without limitation in the present application.

[0048] The liquid storage component 232 is used to buffer the flow of the atomized liquid and to transport the atomized liquid to the heating element 235 by capillary action. The liquid storage component 232 has a hollow structure that can form a vertically penetrating channel, and the inner sleeve 233 is arranged within the channel formed by the liquid storage component 232. A sealing member, such as a silicone ring, can be set between the bottom of the inner sleeve 233 and the bottom of the outer cylinder 231. The inner sleeve 233 prevents direct communication between the liquid storage component 232 and the liquid guiding component 234 inside the inner sleeve 233, and blocks the atomized liquid in the liquid storage component 232 from flowing directly into the hollow channel formed by the liquid storage component 232, thereby preventing leakage. Openings 2331 can be provided on the wall of the inner sleeve 233 to allow atomized liquid in the liquid storage component 232 to be absorbed by the liquid guiding component 234. The liquid guiding component 234 may also include a protruding portion 2341, which extends from the avoidance opening 2332 on the side wall of the inner sleeve 233 and contacts the liquid storage component 232, allowing the atomized liquid that is saturated in the liquid storage component 232 to be gradually supplied to the liquid guiding component 234.

[0049] The heating element 235 is used to heat the atomized liquid to generate an aerosol. The structure of the heating element 235 is not limited, for example, it can include a heating sheet with a cylindrical structure, a thick film heating pipe, etc. The heating element 235 is pressed against the wall of the central hole of the liquid guiding component 234 and is capable of heating the atomized liquid present at the liquid guiding component 234 to generate aerosol. Please refer to Figures 3 and 7. The heating element 235 is connected to lead wires 2351, with the lead wires 2351 passing through the sealing plug 224 to connect with the conductive post 333 in the circuit board assembly 330, allowing the heating element 235 to be energized and generate heat under the control of the circuit board assembly 330, thus heating the surrounding atomized liquid on the liquid storage component 232 and forming an aerosol. The central hole formed by the heating element 235 constitutes the aerosol passage, and the atomization core 230 also includes an aerosol export pipe 236 that is inserted at the top of the inner hole of the inner sleeve 233. The lower end of the aerosol export pipe 236 is in contact with the upper end of the liquid guiding component 234 and communicates with the aerosol passage, while the upper end of the aerosol export pipe 236 is connected to the mouthpiece 212 provided on the liquid storage cup 210, enabling the aerosol to be discharged from the mouthpiece 212. A mouthpiece sealing member, such as a silicone sealing member, can be arranged between the mouthpiece 212, the aerosol export pipe 236, and the outer cylinder 231 to achieve sealing between the atomization core 230 and the liquid storage cup 210. The mouthpiece sealing member can include filter cotton 240, which is used to absorb condensate at the mouthpiece 212.

[0050] The above structure is one embodiment of the atomization core 230. However, the present application does not limit the specific structure of the atomization core 230. The specific structure of the atomization core 230 can refer to existing structures in the related art, and given that it is not directly related to the innovative content of the present application and the technical problems it aims to solve, it will not be elaborated further here.

[0051] The following describes the relevant structure of the second module 300.

[0052] The bottom shell 310 of the second module 300 can connect with the liquid storage cup 210 in the first module 200, securing the first module 200 and the second module 300 together. The connection method between the bottom shell 310 and the liquid storage cup 210 is not limited; it can include snap-fit, interference fit, bonding, fastener connections, and so on. In one specific embodiment, please refer to Figures 2, 4, and 5. The top opening size of the bottom shell 310 is larger, allowing it to fit over the bottom of the liquid storage cup 210 and connect via a snap-fit structure. The front side of the bottom shell 310 and the liquid storage cup 210 can be equipped with an embedding slot 500, which is used for installing a screen once the bottom shell 310 is assembled with the liquid storage cup 210. During assembly, the left and right side surfaces of the bottom shell 310 and the liquid storage cup 210 can be exposed between the first cover body 110 and the second cover body 120, forming the outer side surfaces of the atomization device on both sides.

[0053] The module holder 320 is used to install the circuit board assembly 330, the airflow unit 340, and the linkage structure. The module holder 320 can include an installation cavity, where the circuit board assembly 330 and the airflow unit 340 can be arranged within the installation cavity. In one specific embodiment, the circuit board assembly 330 can include a substrate 331, a pneumatic switch 332, a conductive post 333, and a circuit switch element 334. The pneumatic switch 332 is a common component of the atomization device, capable of detecting pressure changes in the air intake channel, thus providing control reference for the power supply to the heating element 235, allowing the heating element 235 to be energized when airflow is present. The conductive post 333 is used to protrude from the airflow unit 340, allowing connection of the lead wire 2351 drawn from the heating element 235. The circuit switch element 334 is soldered to the substrate 331, used to open the circuit of the atomization device, and can be configured to adjust the power settings of the atomization device, allowing the heating element 235 to operate at different heating powers. The wall of the installation cavity can be fitted with snap-fit features, enabling the circuit board assembly 330 to be secured to the module holder 320 easily.

[0054] Please refer to Figures 3 to 5 and Figures 10 to 11. The airflow unit 340 includes liquid absorbing cotton 341, a liquid absorbing cotton base 342, and a sealing gasket 345. The liquid absorbing cotton 341 can absorb condensate within the atomizer, and the liquid absorbing cotton base 342 has an internal cavity for mounting the liquid absorbing cotton 341, with the top of the internal cavity having a docking interface. The docking interface allows the sealing plug 224 at the bottom of the atomization core 230 to make a sealed connection, thus achieving airflow communication. The thickness of the liquid absorbing cotton 341 is less than the depth of the internal cavity, allowing for the formation of a cavity at the top of the liquid absorbing cotton base 342. At the same time, the bottom wall of the internal cavity of the liquid absorbing cotton base 342 is provided with a through hole, and the liquid absorbing cotton 341 also has a corresponding through hole. The through hole on the bottom wall of the internal cavity and the through hole on the liquid absorbing cotton 341 together form an air pressure hole 344, allowing the cavity formed at the top of the liquid absorbing cotton base 342 to communicate with the pneumatic switch 332. To ensure the reliable operation of the pneumatic switch 332, please refer to Figures 3 and 11. A sealing gasket 345 is provided between the circuit board assembly 330 and the liquid absorbing cotton base 342. The sealing gasket 345 is made from an elastic material, such as silicone, and includes a pad body 3451 and an annular sleeve 3452. The pneumatic switch 332 can be embedded within the annular sleeve 3452, with the lower opening of the annular sleeve 3452 sealingly engaging with the outer side of the bottom of the liquid absorbing cotton base 342. To facilitate the positioning of the sealing gasket 345, the bottom of the liquid absorbing cotton base 342 is provided with a groove, allowing the sealing gasket 345 to be embedded within the groove.

[0055] The liquid absorbing cotton base 342 is equipped with a downward protruding air nozzle 3421, which corresponds to the device switch 350. To achieve accurate control of the airflow by the device switch 350, the sealing gasket 345 includes a docking protrusion 3453 (as illustrated in Figures 5 and 11). The docking protrusion 3453 is provided with a vertically through hole. The air nozzle 3421 can be inserted into the through hole and form a seal with the inner wall of the through hole. The lower end of the docking protrusion 3453 can make elastic contact with the device switch 350 to ensure good airtightness, preventing external gases from leaking from areas outside the device switch 350 and the airflow unit 340. During assembly, the liquid absorbing cotton base 342 can be secured to the circuit board assembly 330 via a snap fit. The through hole on the docking protrusion 3453, the inner hole on the air nozzle 3421, the corresponding opening on the liquid absorbing cotton base 342, and the airflow hole on the sealing plug 224 collectively form the air intake passage. It is understood that in some other embodiments, the air intake passage can also be replaced with other structural forms that can achieve air intake for the atomization core.

[0056] The working state of the atomization device is controlled by the device switch 350, which is movably arranged on the atomization device. Please refer to Figures 2, 3, 5, 9, and 10. In one embodiment, the device switch 350 is located on the bottom of the atomization device module holder 320, which forms a switch sliding seat, allowing the device switch 350 to be movably fitted and operate left and right on the switch sliding seat. In a specific embodiment, the device switch 350 can include a plate-shaped main body 351 and a limiting portion 353 arranged at the left end of the plate-shaped main body 351. The device switch 350 has a width direction that is perpendicular to the movement direction of the device switch 350, and both sides of the width direction of the plate-shaped main body 351 are equipped with thinned portions 3511, which form steps on the bottom surface of the plate-shaped main body 351, enabling it to slide along the left and right direction on the module holder 320. Correspondingly, as shown in Figures 5 and 8, both the front and rear sides of the bottom of the module holder 320 are equipped with upper guiding protrusions 321 and lower guiding protrusions 322, which are arranged along the left and right directions. A sliding groove 323 is formed between the upper guiding protrusions 321 and the lower guiding protrusions 322, allowing the thinned portions 3511 on the sides of the plate-shaped main body 351 to fit into the sliding groove 323 at the far left of the module holder 320 and move along the sliding groove 323. Of course, in some other embodiments, the device switch 350 can also adopt other structural forms to achieve linear movement.

[0057] The circuit switch element 334 in the circuit board assembly 330 can be a toggle switch, where the circuit switch element 334 includes an operating handle 3341. To allow the device switch 350 to be compatible with the toggle switch, please refer to Figures 3, 4, and 8. A switch card slot 352 is provided on the top surface of the device switch 350, located on the right side of the device switch 350. The operating handle 3341 is embedded in the switch card slot 352. When the device switch 350 is moved, the switch card slot 352 can drive the operating handle 3341 to move synchronously, thereby achieving adjustment of the circuit switch element 334.

[0058] To ensure that the device switch 350 accurately moves to the set position when adjusting the gear, in some embodiments, the module holder 320 is provided with more than two positioning grooves 324 (refer to Figure 5), with the device switch 350 featuring a positioning protrusion 3514. Each positioning groove 324 is distributed along the movement direction of the device switch 350, and the positioning protrusion 3514 is used to slide into different positioning grooves 324 during the movement of the device switch 350 to position the device switch 350. Specifically, in the present application, the device switch 350 has three states during movement: a closed state, a first open state, and a second open state, therefore requiring three positioning grooves 324. In some other embodiments, the positioning protrusion 3514 can also be provided on the module holder 320, with positioning grooves 324 on the device switch 350. Additionally, the number of positioning grooves 324 can be increased or decreased as needed.

[0059] To facilitate the operator's movement of the device switch 350, in one embodiment, as shown in Figures 8 and 9, the width direction sides of the plate-shaped main body 351 are equipped with isolation grooves 3512, which extend along the movement direction of the device switch 350. The isolation grooves 3512 form elastic arms 3513 along the side edges of the plate-shaped main body 351. The elastic arms 3513 can elastically deform in the width direction of the plate-shaped main body 351. The elastic arms 3513 are equipped with positioning protrusions 3514.

[0060] On the lower side of the plate-shaped main body 351, an operation protrusion 354 is provided, which protrudes from the lower side of the plate-shaped main body 351, allowing the operator to drive the device switch 350 to translate. The bottom shell 310 is equipped with an avoidance hole 311. The operation protrusion 354 extends into the avoidance hole 311, facilitating operator toggling.

[0061] In one specific embodiment, the device switch 350 is equipped with a first vent hole 3551 and a second vent hole 3552, each vent hole capable of aligning or misaligning with the air intake port 346 of the air intake channel (i.e., the lower opening of the annular sleeve 3452) while the device switch 350 is moved, thereby changing the opening condition of the air intake port 346 during the movement of the device switch 350. The first vent hole 3551 is a through hole that passes through the operation protrusion 354, which helps reduce the size of the device switch 350 and saves space. The second vent hole 3552 is a through hole provided on the plate-shaped main body 351. To achieve airflow regulation, the cross-sectional area of the first vent hole 3551 is smaller than that of the second vent hole 3552. Those skilled in the art can understand that in some other embodiments, the number of vent holes can also be increased or decreased, and additionally, the vent holes can be omitted, allowing the device switch 350 to adjust the amount of coverage over the air intake port 346 during movement to change the opening condition of the air intake port 346. The opening condition can include closed, open, or various degrees of opening.

[0062] The device switch 350 has a first end and a second end, with the first end being the end connected to the linkage structure (i.e., the left end in the figures) and the second end being the end of the device switch 350 away from the linkage structure (i.e., the right end in the figures). The vent holes are arranged between the first and second ends of the device switch 350, which helps reduce the length of the device switch 350, making the structure compact. In some other embodiments, a regulating plate can also be arranged at one end of the device switch 350 along the movement direction, and can be configured separately and fixedly connected to the plate-shaped main body, allowing for flexible adjustment of the setting position as needed.

[0063] Please refer to Figure 3. When the device switch 350 is in the closed state, both vent holes are misaligned with the air intake port 346, and the air intake port 346 is completely sealed by the device switch 350. Please refer to Figure 12. When the device switch 350 is in the first open state, the through hole on the operation protrusion 354 is aligned with the air intake port 346 of the air intake channel, placing the atomization device in the first position. Please refer to Figure 13. When the device switch 350 is in the second open state, the through hole on the operation protrusion 354 is also aligned with the air intake port 346 of the air intake channel, placing the atomization device in the second position, where the airflow of the first position is less than that of the second position.

[0064] The device switch 350 not only can change the opening condition of the air intake port 346 but also can control the opening and closing of the liquid supply switch 250 through the linkage structure. The linkage structure is arranged between the device switch 350 and the liquid supply switch 250, used to open the liquid supply switch 250 when the device switch 350 is switched to the open state. In one embodiment, the linkage structure includes a driving member 360, which is linearly and movably set on the atomization device. The movement direction of the driving member 360 is consistent with the opening movement direction of the liquid supply switch 250, and the driving member 360 is used to push the liquid supply switch 250 to open.

[0065] Please refer to Figures 3, 8, 10, and 11. In one embodiment, the driving member 360 includes a columnar main body 361, two guiding side plates 362, and two wing portions 363. The two guiding side plates 362 are arranged on the front and rear sides of the columnar main body 361 and are positioned at the bottom of the columnar main body 361. Correspondingly, please refer to Figure 4, where the module holder 320 is provided with a guiding space, which includes guiding grooves 325 located on the front and rear sides, extending in the vertical direction and having left and right groove walls. The left and right side surfaces of the guiding side plates 362 are adapted to the left and right groove walls, which help prevent the driving member 360 from tilting, ensuring good guiding performance.

[0066] To better achieve the guiding of the driving member 360, in one embodiment, the columnar main body 361 of the driving member 360 has a hollow inner cavity 3611, with an opening on one side of the hollow inner cavity 3611. The liquid absorbing cotton base 342 of the airflow unit 340 is equipped with a guiding rib 343, which extends along the movement direction of the driving member 360. The guiding rib 343 enters the hollow inner cavity 3611 from the opening, and the guiding rib 343 and the side wall of the hollow inner cavity 3611 are used to guide the driving member 360. In some other embodiments, the guiding rib 343 can also be arranged at other locations on the atomization device, such as on the lateral surface of the liquid storage cup holder 220. Additionally, those skilled in the art will understand that the driving member 360 can be guided by other guiding structures, such as providing guiding holes on the driving member 360 and guiding posts on the module holder 320, with the guiding posts inserted into the guiding holes; alternatively, a dovetail guide rail can be set between the device switch 350 and the driving member 360 to achieve guidance.

[0067] The two wing portions 363 are also arranged on the front and rear sides of the columnar main body 361, with each wing portion 363 connected to the driving spring 400, allowing the driving spring 400 to drive the liquid supply switch 250 to open. The structure of the driving spring 400 will be detailed below.

[0068] In some embodiments, the movement direction of the driving member 360 is consistent with the opening movement direction of the liquid supply switch 250, both moving in the vertical direction. The lower end of the driving member 360 serves as the linkage end that fits with the device switch 350, while the upper end is the driving end used to open the liquid supply switch 250. The driving member 360 is used to push the liquid supply switch 250 to open. In a specific embodiment, the driving end of the driving member 360 has a plug section 364, which includes a head end 3641. The head end 3641 is used to top the liquid supply switch 250. The head end 3641 is connected to the body of the driving member 360 through a support column 3642, with the outer diameter of the support column 3642 being smaller than that of the head end 3641. The plug section 364 is used to insert into the guiding hole 2232 to push the liquid supply switch 250 open. Optionally, the end of the plug section 364 has a chamfer that is used to guide the plug section 364 into the guiding hole 2232. The chamfer set on the support column 3642 and the head end 3641 facilitates the smooth insertion of the driving end of the driving member 360 into the guiding hole 2232, ensuring reliable operation.

[0069] The driving force that the driving member 360 uses to push the liquid supply switch 250 open is provided by the driving spring 400. In one embodiment, the driving spring 400 is a tension spring, with the wing portion 363 being equipped with a hanging protrusion 3631, where the lower end of the tension spring is hooked onto the hanging protrusion 3631. The liquid storage cup holder 220 of the first module 200 has a spring hook 225, and the upper end of the driving spring 400 is connected to the spring hook 225. Two driving springs 400 can be used, each connecting to one wing portion 363, providing ample driving force and achieving a balance of forces on both sides of the driving member 360. It should be noted that in some other embodiments, the driving spring 400 can also be a compression spring, which can be arranged between the module holder 320 and the driving member 360.

[0070] Before the first use of the atomization device, to prevent leakage, the liquid supply switch 250 should be in the closed state, so the driving member 360 needs to be limited to avoid pushing the liquid supply switch 250 open. In one embodiment, a limiting wall 3612 is provided at the end of the hollow inner cavity 3611 of the driving member 360 that is away from the liquid supply switch 250. The device switch 350 has a limiting portion 353, which is used to insert into the hollow inner cavity 3611 and block on the side of the limiting wall 3612 that is close to the liquid supply switch 250, thereby preventing the driving member 360 from moving upward when the device switch 350 is in the closed state. In one embodiment, the side of the plate-shaped main body 351 that is close to the liquid supply switch 250 has a limiting plate 3531 connected to it, which forms the limiting portion 353. The side of the limiting plate 3531 away from the driving member 360 is connected with a vertical plate 3532, where the vertical plate 3532 and the limiting plate 3531 are arranged in an "L" shape, and a reinforcing rib 3533 is provided between the vertical plate 3532 and the plate-shaped main body 351. The reinforcing rib 3533 is positioned on the side of the vertical plate 3532 away from the limiting plate 3531, which serves to prevent the limiting plate 3531 from tilting towards the side close to the liquid supply switch 250. The vertical plate 3532 and the reinforcing rib 3533 enhance the structural stability of the limiting plate 3531, ensuring that the device switch 350 can reliably limit the driving member 360 when in the closed state.

[0071] The opening action of the driving member 360 is realized by the driving spring 400. To prevent the device switch 350 from being overly topped, in one embodiment, as shown in Figures 3, 4, and 10, a limiting step 3643 is provided on the driving member 360. The limiting step 3643 forms a limiting surface facing the liquid supply switch 250, which is used to abut against the edge of the guiding hole 2232 to limit the movement stroke of the driving member 360.

[0072] It should be noted that in some other embodiments, the linkage structure can also be replaced with other structures. For example, the driving member 360 and the liquid supply switch 250 can be integrally formed, or they can be fixedly connected, in which case the linkage structure can be arranged on the liquid supply switch 250 and the device switch 350. Additionally, the outer peripheral surface of the driving member 360 can be provided with a limiting protrusion, and the end of the device switch 350 can directly block the side of the limiting protrusion that is facing the opening movement direction of the driving member 360. Furthermore, the end of the liquid supply switch 250 can extend into the movement path of the device switch 350, and an inclined surface can be set between the liquid supply switch 250 and the device switch 350, relying on the inclined surface to convert the first direction movement of the device switch 350 into the second direction movement of the liquid supply switch 250.

[0073] Moreover, the above linkage structure is a single linkage structure, and the driving member 360 is separated from the device switch 350 after disengagement. In some other embodiments, a linkage relationship can be maintained between the liquid supply switch 250 and the device switch 350, where the opening of the device switch 350 drives the liquid supply switch 250 to open, and the closing of the device switch 350 drives the liquid supply switch 250 to close. For example, the movement direction of the device switch 350 can be set parallel to that of the liquid supply switch 250, allowing the liquid supply switch 250 to be directly connected to the device switch 350 for synchronized movement.

[0074] The above is elaborated through specific examples to help understand the present application and is not intended to limit the present application. Those skilled in the relevant technical field can make various simple deductions, modifications, or substitutions based on the concept of the present application.
