[0037] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of the internal structure of an electronic atomization device provided by an embodiment of the utility model; Figure 2It is a schematic diagram of the structure of the bottom of the liquid tank; Figure 3 This is a schematic diagram of the assembly structure of the liquid tank, microphone bracket module, and circuit board module; Figure 4 It is a structural schematic diagram of a battery cell module being electrically connected to a circuit board module by welding.

[0038] In a specific embodiment, the electronic atomization device provided by the utility model is mainly assembled in a modular form by a shell 10, a liquid tank 20, an atomization module 30, a microphone bracket module 40, a circuit board module 50 (i.e., a PCBA module), a battery cell module 60 and an activation module 70.

[0039] The liquid tank 20 is located at the upper part of the shell 10, and the lower part of the liquid tank 20 is embedded in the opening of the shell 10. The two are connected by riveting and are flat in shape as a whole. A suction nozzle 21 is provided on the top of the liquid tank 20 and a partition 22 is provided inside. The partition 22 can be a material that can be used for support and fixation, such as a combination of silicone or plastic and hardware, etc.

[0040] The separator 22 in this embodiment is steel sheet silicone, that is, silicone with steel sheets embedded inside. By embedding at least one layer of steel sheets inside the silicone, fixed support can be achieved while sealing oil. The two components that originally needed to achieve oil sealing and fixed support are integrated into one component, saving assembly costs and facilitating assembly.

[0041] The partition 22 is provided with an injection hole 23 and an injection plug 24 for sealing the injection hole. The cross-section of the injection hole 23 is circular or oblong, and a plurality of threaded structures are provided on the inner wall to form a large runway-shaped injection hole. Sufficient gaps can be left during injection. During injection, the air inside the liquid tank 20 can be discharged from the gaps in time, thereby achieving pressure relief while injecting liquid, and reducing the difficulty of injection. The partition 22 can also be other materials that can be used for support and fixation, such as simple silicone or steel components with sealing rings around them. After the injection is completed and the injection plug 24 is installed, the modularization of the liquid tank 20 can be realized.

[0042] The partition 22 divides the inner cavity of the liquid tank 20 into a liquid cavity 25 and an assembly cavity 26. The upper portion of the partition 22 is the liquid cavity 25, and the lower portion of the partition 22 is the assembly cavity 26 (Note: Figures 2 to 5 , Figure 7 , Figure 8 The product is shown in an inverted position, and the upside down and upside down positions are described in Figure 1 As a reference), the depth of the liquid cavity 25 is greater than the depth of the assembly cavity 26. The assembly cavity 26 can be conveniently matched with the microphone bracket module 40, and further matched with the circuit board module 50 and the battery module 60 for assembly, thereby improving the overall installation efficiency of the electronic atomization device.

[0043] refer to Figure 2 It can be understood that in the embodiment of the present invention, the assembly cavity 26 is designed to form a connection relationship with the shell 10 and provide a storage space for some components. Therefore, the assembly cavity 26 does not have to be a closed cavity. In some embodiments, the open end of the assembly cavity 26 can be covered or partially covered by an appearance part.

[0044] The nozzle 21 is located at the top of the liquid compartment 20, the partition 22 is provided with a longitudinal channel 221 corresponding to the nozzle 21, the atomization module 30 and the activation module 70 are axially corresponding to the nozzle 21 and the longitudinal channel 221, the battery module 60 and the moving bracket 71 are staggered, and the moving bracket 71 is provided with an air inlet channel 80 connected to the nozzle 21, and a liquid absorbing cotton 81 is arranged inside the air inlet channel 80. Such a layout makes the internal structure of the entire electronic atomization device more reasonable and compact.

[0045] The upper end of the atomizing module 30 penetrates the liquid cavity 25 from the longitudinal channel 221 and is connected to the suction nozzle 21, and can move upward along the longitudinal channel 221, and the lower end thereof is located inside the assembly cavity 26 of the liquid compartment 20. The lower surface of the partition 22 is provided with a liquid-proof silicone rubber 27 and a heating element pin 28 located between the liquid-proof silicone rubber 27 in the area between the atomizing module 30 and the liquid injection hole 23. The liquid-proof silicone rubber 27 can play a role in sealing and isolating the atomized liquid, thereby preventing the atomized liquid from leaking from the area and affecting the electrical connection effect.

[0046] The microphone bracket module 40 is connected to the assembly cavity 26 of the liquid tank 20, the circuit board module 50 is connected to the microphone bracket module 40, and the battery module 60 is laser welded to the pad of the circuit board module 50 through the pole ear. Specifically, the microphone bracket module 40 covers the assembly cavity 26, and the side wall of the assembly cavity 26 is provided with a card hole. The two sides of the microphone bracket module 40 are provided with a card hook, and the card hook is connected with the card hole of the assembly cavity 26. The circuit board module 50 covers the microphone bracket module 40 and is riveted with the microphone bracket module 40. In this way, the microphone bracket module 40, the circuit board module 50 and the battery module 60 can be more flexibly compatible and assembled together in a modular way, which simplifies the assembly steps of the electronic atomization device.

[0047] Two electrodes 51 are provided in the middle of the circuit board module 50, and the microphone bracket module 40 is provided with two electrode holes 41 corresponding to the electrodes 51. The electrodes 51 pass through the electrode holes 41 and contact the heating element pins 28 on the separator 22 in the liquid-proof silicone 27 to be energized. In this way, the electrodes 51 can realize the conductive connection and riveting functions at the same time, without adding riveting parts for connection, simplifying the structure, saving the number of parts, and facilitating assembly.

[0048] The activation module 70 has a moving bracket 71 and a spring 72. In the unactivated state, the moving bracket 71 pre-compresses the spring 72 and is locked with the housing 10. At this time, the liquid inlet 31 of the atomization module 30 does not enter the liquid cavity 25, but is located in the longitudinal channel 221 and is in sealing contact with the inner wall of the longitudinal channel 221, so the atomized liquid will not enter the atomization module 30. In the activated state, the moving bracket 71 is unlocked from the housing 10, and the spring 72 supports the moving bracket 71 and the atomization module 30 to move upward, so that the liquid inlet 31 of the atomization module 30 enters the liquid cavity 25, so that the atomized liquid enters the atomization module 30 from the liquid inlet 31 for atomization. This liquid core separation structure solves the risk of the atomization module 30 being immersed in the atomized liquid for a long time and producing a poor taste.

[0049] In order to achieve axial sealing, the suction nozzle 21 is provided with an inner liner tube 211 extending downward into the liquid chamber 25. A sliding head 32 is provided at the upper end of the atomization module 30. The inner wall of the inner liner tube 211 and the sliding head 32 are sealed by a sealing ring. The sliding head 32 can move up and down in the axial direction in a sealed state, thereby sealing and isolating the inner liner tube 211 and preventing the atomized liquid from leaking from the liquid chamber 25.

[0050] The microphone bracket module 40 is provided with a sleeve 42 corresponding to the atomizer module 30 and extending downward, and the circuit board module 50 is provided with a clearance hole 52 for passing the sleeve 42. On the one hand, this sleeve 42 can accommodate the lower end of the atomizer module 30. On the other hand, the upper end of the moving bracket 71 slides up and down with the inner wall of the sleeve 42 and is provided with a sealing ring, which plays a role of sealing and isolation to prevent the atomized liquid from leaking from the bottom of the moving bracket 71.

[0051] Please continue to refer to Figures 5 to 8 , Figure 5 It is a schematic diagram of the structure of the motion bracket 71 matching with the microphone bracket module 40 and the circuit board module 50; Figure 6 It is a structural schematic diagram of the moving base 711 of the moving bracket 71 when it is in a locked state; Figure 7 It is a schematic structural diagram of the riveted connection between the shell 10 and the liquid tank 20; Figure 8 It is a structural schematic diagram of the movable bracket 71 being locked by the stopper 73.

[0052] As shown in the figure, the moving bracket 71 can be an integrated structure or a split structure. If the moving bracket 71 is a split structure, it can be divided into two parts: a moving base 711 and a bracket 712. The spring 72 is arranged between the moving base 711 and the bottom of the shell 10. One end of the bracket 712 abuts against the atomization module 30, and the other end abuts against the moving base 711.

[0053] In a possible implementation, the moving base 711 is a hollow structure, and two claws 713 extending downward in the axial direction are provided on the inner top thereof, the spring 72 is sleeved on the claws 713, and is located between the inner top of the moving base 711 and the bottom of the housing 10, the upper end of the bracket 712 abuts against the lower end of the atomization module 30, and the lower end of the bracket 712 abuts against the upper end of the moving base 711, so as to transmit the elastic force of the spring 72 to the atomization module 30, push the atomization module 30 to move upward, make the liquid inlet of the atomization module 30 enter the liquid cavity, and fix the atomization module 30 in the liquid cabin 20. In this way, the atomized liquid can smoothly enter the atomization module 30 from the liquid inlet from the liquid cabin 20, and can work normally.

[0054] The main part of the bracket 712 is cross-shaped in cross section, and a piston head 714 is provided at its upper end. The piston head 714 slides up and down with the sleeve 42 extending downward from the microphone bracket module 40. A circumferential sealing ring is provided on the piston head 714, and the inner wall of the sleeve 42 and the piston head 714 are sealed by the sealing ring. The piston head 714 can move up and down in the axial direction at the same time in a sealed state, and a baffle 43 is provided on one side of the sleeve 42 to isolate the sleeve 42 and the battery cell module 60 from each other.

[0055] A trigger portion 715 extending toward the nozzle is provided on one side of the bracket 712, and an activation switch 53 corresponding to the trigger portion 715 is provided on the circuit board module 50. When the product is in an inactive state, the trigger portion 715 is a certain distance away from the activation switch 53, and the distance should be less than the distance that the bracket 712 moves upward after activation, so that when the product is in an activated state, after the bracket 712 moves upward, the activation switch 53 can be triggered by the trigger portion 715, thereby conducting the circuit and enabling the product to work normally.

[0056] In a possible implementation, a through hole corresponding to the claw 713 is provided at the bottom of the housing 10 , a releasable stopper 73 is provided outside the through hole, and the stopper 73 is provided with a locking hole 731 for locking the claw 713 .

[0057] The stopper 73 is a plastic sheet in a rectangular shape, and is provided with two holes 731 corresponding to the claws 713. The claws 713 can be locked through the holes 731 to keep the spring 72 in a pre-compressed state, and can be removed to release the locking of the claws 713 and release the spring 72. The spring 72 drives the atomization module 30 to move upward through the bracket 712. The outer end of the stopper 73 is provided with a protrusion 732 that exceeds the edge of the housing 10, so that the user can push the stopper 73 away when activating the atomization device. This automatic activation method is simple to operate, highly practical, and convenient for users to use.

[0058] Of course, in another possible implementation, the activation module can also be provided on the movable bracket 71 with a locking section that can extend out of the shell 10 along the extension and contraction direction of the spring 72, and the locking section is provided with a locking hole. When the stopper 73 is inserted into the locking hole, the movable bracket 71 is locked, and when the stopper 73 is moved away from the locking hole, the movable bracket 71 is released and can move upward.

[0059] The above embodiments are only preferred solutions of the present invention and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, the air intake passage 80 can be a longitudinal integrated structure or a segmented structure, etc. Since there are many possible implementation methods, they will not be described one by one here.

[0060] The electronic atomization device is divided into multiple modules and assembled in a modular form, which can significantly improve product quality and make the product flexible in compatibility. It has the characteristics of a small number of parts, simple steps, and easy assembly. It can effectively reduce the difficulty coefficient of operation for assemblers, and can achieve liquid core separation and automatic activation, so that the product has better stability and good taste.
