[0037] Based on the installation requirement of the control button 300, an electronic atomization device usually needs to specifically provide a button fixing structure on the housing, resulting in a more cumbersome installation process where the button fixing structure needs to be installed first and then the control button 300. Moreover, it is necessary to reserve the design space for the button fixing structure, making the overall structure less compact.

[0038] In an embodiment of the present application, the control button 300 is disposed in the first through hole 120 and is configured to have a first state and a second state. When assembling the inner housing 100 into the outer housing 200, the control button 300 is adjusted to the second state so that the control button 300 can be inserted into the outer housing 200 together with the inner housing 100. After the assembly is completed, the control button 300 switches to the first state to extend into the second through hole 220, thereby being exposed outside the outer housing 200. The installation is relatively simple, and there is no need to specifically design a fixing structure, which helps to improve the structural compactness of the electronic atomization device.

[0039] An embodiment discloses an electronic atomization device. Please refer to Figures 1-5, the electronic atomization device includes an inner shell 100, an outer shell 200, a control button 300, and other components provided as needed.

The outer shell 200 is sleeved outside the inner shell 100, the outer shell 200 is of a cylindrical structure, and at least one end of the outer shell 200 along its axial direction is provided with an assembly port 210 for the inner shell 100 to enter, and the side wall of the outer shell 200 has a second through hole 220, and the second through hole 220 is correspondingly arranged with the first through hole 120. The control button 300 is movably limited in the first through hole 120 along the triggering direction of the push-adjustment switch 410, the control button 300 has a first state and a second state, when the control button 300 is in the first state, the side of the control button 300 away from the push-adjustment switch 410 is located in the second through hole 220; when the control button 300 is in the second state, the control button 300 is separated from the second through hole 220 and is located inside the outer shell 200.

[0041] The control button 300 is arranged in the first through hole 120 for pre-installation on the inner shell 100 in advance. The control button 300 has a second state, so that when the inner shell 100 and the outer shell 200 are assembled, the control button 300 can be adjusted to the second state to avoid interference of the pre-installation of the control button 300 on the installation of the inner shell 100 into the outer shell 200 for installation. And the first state of the control button 300 can ensure that after the inner shell 100 and the outer shell 200 are assembled, the control button 300 can be located in the second through hole 220 to be exposed outside the outer shell 200 to realize control from the outside of the electronic atomization device.

[0042] Exemplarily, please refer to Figures 2-4 , the inner shell 100 is set as a cylinder with openings at both ends, the push-adjustment switch 410 is arranged in the middle area of the inner cavity 110 along its axial direction, and the first through hole 120 is arranged in the middle of one side wall of the inner shell 100 and is correspondingly arranged opposite to the triggering part of the push-adjustment switch 410. One end of the outer shell 200 along its axial direction is provided with an assembly port 210, and a sealing member 211 for closing the assembly port 210 is provided, such as a bottom cover, a base, etc.; a suction nozzle 230 is provided at the other end of the outer shell 200 along its axial direction, and the second through hole 220 is correspondingly arranged in the middle of one side wall of the outer shell 200, and one side of the control button 300 is movably arranged in the first through hole 120 and the other side extends into the second through hole 220.

[0043] During assembly, first load the circuit board assembly 400 and other required components into the inner shell 100, and load the control button 300 into the first through hole 120. When installing, align the triggering part of the push adjustment switch 410 with the first through hole 120, that is, align the control button 300 and the triggering part of the push adjustment switch 410. Then insert the inner shell 100 into the outer shell 200 from the assembly port 210. Before inserting the control button 300 into the outer shell 200, press the control button 300 to the second state. After the inner shell 100 is inserted in place, the second through hole 220 is aligned with the first through hole 120, the control button 300 switches to the first state, and one side of the control button 300 extends into the second through hole 220. Finally, seal the assembly port 210 to complete the installation.

[0044] In one embodiment, please refer to Figure 4 and Figure 5 , a protruding portion 310 is provided on the side of the control button 300 close to the push adjustment switch 410. The protruding portion 310 is used to abut and limit the side wall of the inner shell 100 along the axial direction of the first through hole 120. The provided protruding portion 310 can serve as an anti-detachment structure for the control button 300 to prevent the control button 300 from detaching from the first through hole 120 and the second through hole 220 during use.

[0045] Exemplarily, please refer to Figures 4-5 , extension arms 311 are provided on the side of the control button 300 opposite to the push adjustment switch 410 along the triggering direction of the push adjustment switch 410. Two extension arms 311 are arranged side by side at intervals. The ends of the two extension arms 311 close to the push adjustment switch 410 are provided with protruding portions 310, and the protruding portions 310 on the two extension arms 311 are arranged in opposite directions. When the control button 300 moves away from the push adjustment switch 410 along the axial direction of the first through hole 120, the protruding portion 310 can abut against the side wall of the inner shell 100 around the first through hole 120 to limit the movement of the control button 300 and prevent the control button 300 from detaching from the first through hole 120. During assembly, the control button 300 can be inserted into the first through hole 120 from the inner cavity 110 of the inner shell 100 in advance, and then the circuit board assembly 400 is installed. In some embodiments, the extension arms 311 can be made of an elastic material that can produce elastic deformation, so that the protruding portion 310 can be inserted into the inner cavity 110 of the inner shell 100 from the first through hole 120, so as to reduce the limitation on the assembly sequence and improve the assembly flexibility.

[0046] In one embodiment, please refer to Figure 4 and Figure 5, on one side of the side wall of the control button 300 close to the pressing adjustment switch 410, there is a limit card slot 320. The slot wall and the protruding part 310 on the side of the limit card slot 320 far from the pressing adjustment switch 410 are respectively clamped on the inner and outer side walls of the inner shell 100, and the width of the limit card slot 320 along the axial direction of the first through hole 120 is greater than the wall thickness of the hole wall of the first through hole 120. The limit card slot 320 is used to abut and limit with the outer side wall of the inner shell 100 along the axial direction of the first through hole 120, so as to limit the pressing depth of the control button 300, which helps to avoid damaging the pressing adjustment switch 410 due to excessive pressing of the control button 300 during use, and realizes the limitation of the pressing range of the control button 300 in cooperation with the setting of the protruding part 310.

[0047] Exemplarily, there are two limit card slots 320 corresponding to the extension arms 311. The limit card slot 320 has a slot wall flush with the side wall of the extension arm 311 provided with the protruding part 310, so that the inner shell 100 is clamped in the gap between the limit card slot 320 and between the limit card slot 320 and the protruding part 310, that is, clamped between the slot wall of the limit card slot 320 far from the pressing adjustment switch 410 and the protruding part 310. When installing the control button 300, insert the protruding part 310 and the extension part from the side of the first through hole 120 facing away from the inner cavity 110 of the inner shell 100, so that the protruding part 310 extends into the inner cavity 110 of the inner shell 100, and verify that the protruding part 310 can abut and limit with the side wall of the inner shell 100 along the axial direction of the first through hole 120. In other embodiments, the number and position of the limit card slots 320 can also be set as needed, as long as the design purpose of limiting the pressing depth of the control button 300 can be achieved.

[0048] In one embodiment, please refer to Figure 5 , the circuit board assembly 400 further includes a circuit board 420. The pressing adjustment switch 410 is arranged on the circuit board 420. On at least one side of the pressing adjustment switch 410 on the circuit board 420, there is a light emitter 430. The light emitter 430 is used to emit light to the control button 300, and the material of the control button 300 is a light-transmitting material. Setting the light emitter 430 and using the control button 300 made of a light-transmitting material can make the control button 300 serve as a light guide button, which is convenient for use in an environment with poor lighting conditions.

[0049] Exemplarily, the pressing adjustment switch 410 and the light emitter 430 are arranged on the same side of the circuit board 420, and light emitters 430 are arranged on both sides of the pressing adjustment switch 410. The light emitter 430 can be an LED lamp bead or other elements capable of emitting light. And the material of the control button 300 can be acrylic material, transparent silicone material or other materials capable of transmitting light.

[0050] In a further embodiment, please refer to Figure 4 andFigure 5 , an elastic pad 330 is provided between the control button 300 and the pressing adjustment switch 410. The material of the elastic pad 330 is a light-transmitting material. The setting of the elastic pad 330 can provide button touch, reduce button noise, and also help to reduce the precision requirements for the production and assembly of the control button 300 and the pressing adjustment switch 410.

[0051] Exemplarily, a concave cavity 340 is provided on one side of the control button 300 close to the pressing adjustment switch 410. The opening of the concave cavity 340 faces the triggering part of the pressing adjustment switch 410, and the elastic pad 330 can be embedded in the concave cavity 340. The elastic pad 330 can be a rubber pad. Based on the light-transmitting requirement of the elastic pad 330, for example: transparent silicone, transparent polyurethane or other transparent / translucent elastic materials can be used.

[0052] In one embodiment, please refer to Figure 2 and Figure 3 , the electronic atomization device further includes an atomizer 500 and a battery assembly 600 provided in the inner cavity 110. The atomizer 500 and the battery assembly 600 are respectively arranged on both sides of the circuit board 420 in the board thickness direction, and the circuit board 420 is fixed on the atomizer 500. During installation, the atomizer 500 fixed with the circuit board 420 can be first installed from the opening at one end of the inner shell 100, then the battery assembly 600 can be installed from the opening at the other end of the inner shell 100, and then the outer shell 200 can be sleeved. Of course, the battery assembly 600 can also be installed into the inner cavity 110 of the inner shell 100 from the assembly port 210 of the outer shell 200 after the outer shell 200 is sleeved. Among them, the battery assembly 600 can be understood as a module for power supply, for example: a battery, an assembly of a battery and a battery holder, or an assembly of a battery, a battery holder and other battery-related structural parts.

[0053] In one embodiment, please refer to Figure 3 and Figure 5 , the pressing adjustment switch 410 is arranged on the side of the circuit board 420 facing the battery assembly 600. Exemplarily, the pressing adjustment switch 410 and the light-emitting body 430 are arranged on the same side of the circuit board 420, specifically on the side facing the battery assembly 600, so as to avoid interference with the atomizer 500 or affecting the design of the atomizer 500.

[0054] In one embodiment, please refer to Figure 5, the atomizer 500 includes a housing 510, and one end of the housing 510 has an elastic arm 514, and the elastic arm 514 is arranged in pairs on opposite sides of the housing 510, and the circuit board 420 is clamped between the elastic arms 514. The circuit board 420 is clamped and fixed by the set elastic arms 514, which is convenient for assembly. Exemplarily, the opposite sides of the circuit board 420 have an inner recess 421 that is recessed toward the middle of the circuit board 420, and the inner recess 421 is used for the elastic arm 514 to clamp. During assembly, the circuit board 420 is pressed onto the end of the housing 510 after aligning the inner recess 421 with the elastic arm 514. In other embodiments, the elastic arm 514 can also be directly clamped to the peripheral side of the circuit board 420, or a clamping hole corresponding to the elastic arm 514 is set on the circuit board 420, so that the elastic arm 514 can be inserted to achieve clamping and fixing. In short, any setting method that can cooperate with the elastic arm 514 to achieve fixation is acceptable.

[0055] For a further embodiment, please refer to Figure 5 A fixing slot 5141 is provided on the elastic arm 514, and a clamping protrusion 422 is provided on the peripheral side of the circuit board 420 corresponding to the fixing slot 5141, and the clamping protrusion 422 is clamped in the fixing slot 5141. The clamping protrusion 422 cooperates with the fixing slot 5141, which can further improve the fixing quality and help reduce the possibility of the circuit board 420 and the housing 510 being separated.

[0056] For example, the fixed card slot 5141 is arranged in the middle area of the elastic arm 514, and the fixed card slot 5141 is arranged in a square hole shape, and a clamping protrusion 422 is arranged in the middle of the inner concave portion 421 in a direction away from the middle of the circuit board 420. During installation, the elastic arm 514 is bent so that the clamping protrusion 422 is inserted into the fixed card slot 5141, and then the circuit board 420 can be clamped under the action of the elastic arm 514.

[0057] In order to achieve accurate assembly of the circuit board 420 and the atomizer 500, please refer to Figure 5, the atomizer 500 and the circuit board 420 have a foolproof design. For example, in one embodiment, the atomizer 500 includes alignment posts 520 for positioning the circuit board 420, and the circuit board 420 has alignment jacks 423 for inserting the alignment posts 520. Exemplarily, two alignment posts 520 and two alignment jacks 423 are provided. The two pairs of alignment jacks 423 are disposed at two diagonally opposite corners of the circuit board 420, and the alignment posts 520 and the alignment jacks 423 are correspondingly arranged. For another example, in one embodiment, the atomizer 500 has an air intake post 530, and the circuit board 420 has an air intake jack 424 for the air intake post 530 to pass through. Exemplarily, the air intake post 530 of the atomizer 500 is disposed at a corner of the atomizer 500 and is used as an air flow inlet of the atomizer 500. The air intake jack 424 is correspondingly disposed at a corner of the circuit board 420 corresponding to the air intake post 530 and is communicated and merged with one alignment jack 423. For yet another example, in one embodiment, the atomizer 500 has power connection pins 540, and the circuit board 420 has pin holes 425 for the power connection pins 540 to pass through. Exemplarily, the atomizer 500 has power connection pins 540 on one side for connecting to the side of the circuit board 420 facing away from the atomizer 500, and the circuit board 420 is provided with pin holes 425 for the power connection pins 540 to pass through on the side away from the push adjustment switch 410.

[0058] It should be noted that, for the foolproof structures listed above, one, two or three of them can be selectively set in different embodiments. Of course, other forms of foolproof design can also be adopted as long as the foolproof effect can be achieved so that the circuit board 420 can be accurately assembled.

[0059] In one embodiment, please refer to Figure 2 and Figure 5 , a convex edge 511 is provided on the side of the housing 510 facing away from the circuit board 420, and the convex edge 511 is used to abut against the end face of one end of the inner housing 100.

The mouthpiece 230 can form a limiting structure for the inner housing 100 to prevent the inner housing 100 from coming out. During assembly, first insert the end of the atomizer 500 away from the convex edge 511 into the inner housing 100, and abut the convex edge 511 against the end face of one end of the inner housing 100 to limit the atomizer 500 to one side of the inner cavity 110 of the inner housing 100. Then insert the end of the inner housing 100 with the atomizer 500 into the outer housing 200 from the assembly port 210 until it abuts against the mouthpiece 230 partially. Then insert the battery assembly 600 into the assembly port 210 and use a sealing member 211 such as a bottom cover or a base to seal the assembly port 210 to complete the installation.

[0060] In some embodiments, please refer to Figure 5 , on the side wall of the housing 510 where the convex edge 511 is provided, there is a convex rib 512, so that the housing 510 can be clamped around the inner wall of the inner housing 100 during assembly.
