Description

Technical Field

For an atomization device using an atomization liquid, it includes a liquid storage chamber and an atomization core. The liquid storage chamber is used to store the atomization liquid, and the atomization core includes a heating element. The heating element can heat the atomization liquid entering the atomization core to form an aerosol.

[0003] In order to work properly, the atomization core is not only connected to the liquid storage chamber, but also connected to an air supply channel and an exhaust channel for the aerosol. Therefore, the atomization liquid entering the atomization core may leak from the air supply channel and the exhaust channel. To avoid the leakage of the atomization liquid, in the related art, a blocking structure is considered to be added between the liquid storage chamber and the atomization core. Before the atomization device is used for the first time, the blocking structure can isolate the liquid storage chamber from the atomization core, thereby avoiding the leakage of the atomization liquid.

[0097] The circuit switch element 334 in the circuit board assembly 330 can be a toggle switch. The circuit switch element 334 includes an operating handle 3341. To adapt the device switch 350 to the toggle switch, please refer to Figure 3 , Figure 4 and Figure 8 . A switch slot 352 is provided on the top surface of the device switch 350. The switch slot is provided at the right end of the device switch 350. The operating handle 3341 is embedded in the switch slot 352. When the device switch 350 moves, the switch slot 352 can drive the operating handle 3341 to move synchronously, so as to realize the adjustment of the circuit switch element 334.

[0098] To enable the device switch 350 to accurately move to the set position when adjusting the gear, in some embodiments, two or more positioning slots 324 are provided on the module bracket 320 (reference can be made to Figure 5 ), and a positioning convex portion 3514 is provided on the device switch 350. The positioning slots 324 are distributed along the moving direction of the device switch 350. The positioning convex portion 3514 is used to slide into different positioning slots 324 when the device switch 350 moves, so as to position the device switch 350. Specifically, in the present utility model, the device switch 350 has three states when moving, namely the closed state, the first open state, and the second open state. Therefore, the number of the positioning slots 324 is three. In some other embodiments, the positioning convex portion 3514 can also be provided on the module bracket 320, and the positioning slot 324 can be provided on the device switch 350. In addition, the number of the positioning slots 324 can be increased or decreased according to requirements.

[0099] To facilitate the operator to move the device switch 350, in one embodiment, as shown in Figure 8 and Figure 9 , isolation slots 3512 are provided on both sides in the width direction of the plate-shaped main body 351. The isolation slots 3512 extend along the moving direction of the device switch 350. The isolation slots 3512 form elastic arms 3513 on the side of the plate-shaped main body 351. The elastic arms 3513 can elastically deform along the width direction of the plate-shaped main body 351, and the positioning convex portion 3514 is provided on the elastic arms 3513.

[0100] An operating convex portion 354 is provided on the lower side plate surface of the plate-shaped main body 351. The operating convex portion 354 protrudes from the lower side plate surface of the plate-shaped main body 351.

[0101] In a specific embodiment, the plate-shaped body 351 forms an adjustment plate, and the adjustment plate is provided with a first vent hole 3551 and a second vent hole 3552, and each vent hole can be aligned or staggered with the air inlet port 346 (i.e., the lower end opening of the annular sleeve 3452) of the air inlet passage when the device switch 350 moves, so as to change the opening condition of the air inlet port 346 when the device switch 350 moves. Among them, the first vent hole 3551 is a through hole that penetrates the operating protrusion 354, which is conducive to reducing the size of the device switch 350 and helping to save space. The second vent hole 3552 is a through hole provided on the plate-shaped body 351. In order to adjust the air intake amount, the cross-sectional area of ​​the first vent hole 3551 is smaller than the cross-sectional area 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. The above-mentioned opening condition can include closing, opening, and different degrees of opening.

[0102] The device switch 350 has a first end and a second end, the first end being the end of the device switch 350 connected to the linkage structure, i.e., the left end in the figure, and the second end being the end of the device switch 350 away from the linkage structure, i.e., the right end in the figure. The vent hole is arranged between the first end and the second end of the device switch 350, which is conducive to reducing the length dimension of the device switch 350 and making the structure compact. In some other embodiments, the adjustment plate can also be arranged at one end of the device switch 350 along the movable direction of the device switch 350, and can be arranged separately from the plate-shaped body and fixedly connected, so that the setting position can be flexibly adjusted as needed.

[0103] Please refer to Figure 3 When the device switch 350 is in the closed state, the two vents are staggered with the air inlet port 346, and the air inlet port 346 is completely closed by the device switch 350. Figure 12 When the device switch 350 is in the first on state, the through hole on the operating protrusion 354 is aligned with the air inlet port 346 of the air inlet passage, and the atomizing device is in the first gear position. Figure 13 When the device switch 350 is in the second on state, the through hole on the operating protrusion 354 is aligned with the air inlet port 346 of the air inlet passage, the atomizing device is in the second gear, and the air intake volume of the first gear is less than the air intake volume of the second gear.

[0104] In addition to being able to change the opening state of the intake port 346, the device switch 350 can also control the opening and closing of the liquid supply switch 250 through a linkage structure. The linkage structure is arranged between the device switch 350 and the liquid supply switch 250 and is used to open the liquid supply switch 250 when the device switch 350 is switched to the on state. In one embodiment, the linkage structure includes a driving member 360. The driving member 360 is movably arranged on the atomizing device along a straight line, and the moving direction of the driving member 360 is the same as the opening movement direction of the liquid supply switch 250. The driving member 360 is used to push the liquid supply switch 250 to open.

[0105] Please refer to Figure 3 , Figure 8 , Figure 10 and Figure 11 , in one embodiment, the driving member 360 includes a columnar main body 361, two guiding side plates 362 and two wing parts 363. The two guiding side plates 362 are arranged on the front and rear sides of the columnar main body 361 and are located at the bottom of the columnar main body 361. Correspondingly, please refer to Figure 4 , a guiding space is provided on the module bracket 320. The guiding space includes guiding grooves 325 located on the front and rear sides. The guiding grooves 325 extend in the up and down direction and have a left side wall and a right side wall. The left and right direction side surfaces of the guiding side plates 362 are respectively adapted to the left side wall and the right side wall, which is beneficial to avoid the yaw of the driving member 360 and ensure a good guiding effect.

[0106] In order to better realize 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. One side of the hollow inner cavity 3611 is provided with an opening. A guiding rib 343 is provided on the liquid absorption cotton base 342 of the gas path unit 340. The guiding rib 343 extends along the moving direction of the driving member 360. The guiding rib 343 enters the hollow inner cavity 3611 from the opening. The guiding rib 343 and the side wall of the hollow inner cavity 3611 form a guide for the driving member 360. In some other embodiments, the guiding rib 343 can also be arranged at other parts of the atomizing device, such as on the lateral surface of the liquid storage cup bracket 220. In addition, those skilled in the art can understand that the driving member 360 can be guided by other guiding structures. For example, guiding holes can be provided on the driving member 360, and guiding columns can be provided on the module bracket 320, and the guiding columns are inserted into the guiding holes; another example is that a dovetail guide rail can be arranged between the device switch 350 and the driving member 360, and the guiding is realized by relying on the dovetail guide rail.

[0107] The two wing parts 363 are also arranged on the front and rear sides of the columnar main body 361. The two wing parts 363 are respectively used to connect with the driving spring 400 and can drive the liquid supply switch 250 to open under the drive of the driving spring 400. The structure of the driving spring 400 will be specifically introduced below.

[0108] In some embodiments, the moving direction of the driving member 360 is the same as the opening movement direction of the liquid supply switch 250, both along the up and down direction. The lower end of the driving member 360 is a linkage end adapted to the device switch 350, and the upper end is a driving end for driving the liquid supply switch 250 to open. 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-in portion 364. The plug-in portion 364 includes a head end 3641, and the head end 3641 is used to push the liquid supply switch 250; the head end 3641 is connected to the main body of the driving member 360 through a support column 3642, and the outer diameter of the support column 3642 is smaller than the outer diameter of the head end 3641. The plug-in portion 364 is used to be inserted into the guiding hole 2232 to push the liquid supply switch 250 to open. Optionally, a chamfer is provided at the end of the plug-in portion 364, and the chamfer is used to guide the plug-in portion 364 to be inserted into the guiding hole 2232. The chamfers provided on the support column 3642 and the head end 3641 of the plug-in portion 364 can facilitate the driving end of the driving member 360 to be smoothly inserted into the guiding hole 2232 and ensure the reliability of the action.

[0109] The driving force for the driving member 360 to push the liquid supply switch 250 to open is provided by the driving spring 400. In one embodiment, the driving spring 400 is a tension spring, and a hanging protrusion 3631 is provided on the wing portion 363. The lower end of the tension spring is hooked on the hanging protrusion 3631; a spring hook 225 is provided on the liquid storage cup bracket 220 of the first module 200, and the upper end of the driving spring 400 is connected to the spring hook 225. The number of the driving springs 400 is two, which can be respectively connected to one wing portion 363, can provide sufficient driving force, and can achieve the force balance on the front and rear 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, and the compression spring can be arranged between the module bracket 320 and the driving member 360.

[0110] Before the atomizing device is used for the first time, in order to avoid liquid leakage, the liquid supply switch 250 should be in the closed state. Therefore, the driving member 360 needs to be limited to prevent it from pushing the liquid supply switch 250 to open. In one embodiment, a limiting wall 3612 is provided at one end of the hollow inner cavity 3611 of the driving member 360 away from the liquid supply switch 250. The device switch 350 has a limiting portion 353. The limiting portion 353 is used to insert into the hollow inner cavity 3611 and block on the side of the limiting wall 3612 close to the liquid supply switch 250, so as to be able to block the upward movement of the driving member 360 when the device switch 350 is in the closed state. In a specific embodiment, a limiting plate 3531 is connected to the side plate surface of the plate-shaped main body 351 close to the liquid supply switch 250, and the limiting plate 3531 forms the limiting portion 353; a vertical plate 3532 is connected to the side of the limiting plate 3531 away from the driving member 360. The vertical plate 3532 and the limiting plate 3531 are arranged in an "L" shape. A reinforcing rib 3533 is provided between the vertical plate 3532 and the plate-shaped main body 351. The reinforcing rib 3533 is arranged on the side of the vertical plate 3532 away from the limiting plate 3531 to prevent the limiting plate 3531 from deflecting towards the side close to the liquid supply switch 250. Through the vertical plate 3532 and the reinforcing rib 3533, the structural stability of the limiting plate 3531 can be improved, ensuring that the device switch 350 can reliably limit the driving member 360 when in the closed state.

[0111] The opening action of the above-mentioned driving member 360 is realized by relying on the driving spring 400. In order to avoid the device switch 350 being pushed too much, in one embodiment, as Figure 3 , Figure 4 , Figure 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, and the limiting surface is used to abut against the edge of the guiding hole 2232 to limit the movement stroke of the driving member 360.

[0112] It should be noted that in some other embodiments, the linkage structure can also be replaced by other structures. For example, the driving member 360 and the liquid supply switch 250 can be an integrally formed structure, or the driving member 360 and the liquid supply switch 250 can be fixedly connected. At this time, the linkage structure can be arranged on the liquid supply switch 250 and the device switch 350; another example is that a limiting protrusion can be provided on the outer peripheral surface of the driving member 360, and the end of the device switch 350 can directly block on the side of the limiting protrusion facing the opening movement direction of the driving member 360. Another example is that the end of the liquid supply switch 250 can be extended to the moving path of the device switch 350, and an inclined surface is provided between the liquid supply switch 250 and the device switch 350, relying on the inclined surface to convert the movement in the first direction of the device switch 350 into the movement in the second direction of the liquid supply switch 250.

[0113] In addition, the above linkage structure is a single - time linkage structure. After the driving member 360 is disengaged from the device switch 350, it remains separated from the device switch 350. In some other embodiments, a linkage relationship can be maintained between the liquid supply switch 250 and the device switch 350. When the device switch 350 is turned on, it drives the liquid supply switch 250 to turn on, and when the device switch 350 is turned off, it drives the liquid supply switch 250 to turn off. For example, the moving direction of the device switch 350 can be set to be parallel to the liquid supply switch 250. At this time, the liquid supply switch 250 can be directly connected to the device switch 350 to achieve synchronous movement.

[0114] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention.
