[0043] In modern life, circuit control is an essential function of many products, and switches, as key components for realizing circuit control, have a wide variety of types. In the field of atomization equipment, although products with push-button switches are popular due to convenient operation and personalized experience, the complex touch switch structure currently used by the mainstream has pushed up manufacturing costs, affecting product profit margins and market competitiveness. Therefore, reducing the manufacturing cost of switches is crucial to improving the market competitiveness of atomization product equipment. To this end, the present application provides a power module 102 and an atomization device 100.

The power module 102 is used to supply power to the atomization module 101 to ensure that the atomization module 101 can perform atomization work normally. The power module 102 can also be called a power module 102.

[0045] See also Figures 4 to 6, a power module 102 provided by an embodiment of the utility model is applied to the aforementioned atomization device 100, the power module includes a circuit board 14 and a switch assembly, the circuit board 14 is provided with a conductive contact 141, and the circuit board 14 carries a circuit capable of performing at least one function. Among them, the conductive contact 141 is used to couple the circuit, the circuit board 14 is a printed circuit board (PCB), and the circuit board 14 may also be provided with a pneumatic switch, such as a microphone. The switch assembly at least includes an elastic conductive member 20, one end of the elastic conductive member 20 is fixedly connected to the circuit board 14 to couple the circuit, and is ready for the circuit to be connected, and the other end of the elastic conductive member 20 is suspended, and can produce elastic deformation when subjected to external force to achieve bending of the shape. The switch assembly has an open state and a closed state. When the switch assembly is in the open state, the elastic conductive member 20 contacts the conductive contact 141, and the circuit is turned on, so that the atomization device 100 performs at least one function. When the switch assembly is in the closed state, the elastic conductive member 20 is suspended, and the circuit is disconnected. In this embodiment, the switch component is used to control the power of the atomization device 100 to achieve a power regulation function. Specifically, when the switch component is in an on state, the atomization device 100 operates in a high-power state, and when the switch component is in a off state, the atomization device 100 operates in a low-power state; or, the switch component is used to control the voltage of the atomization device 100 to achieve a voltage regulation function. Specifically, when the switch component is in an on state, the atomization device 100 operates in a high-voltage state, and when the switch component is in a off state, the atomization device 100 operates in a low-voltage state. In some other embodiments, the switch component can also be used to implement functions such as atomization control, microphone control, display control, and lighting effect control of the atomization device 10. For example, when the switch component is in the on state, the atomization device 100 controls the atomization core to heat up and atomize, and when the switch component is in the off state, the atomization device 100 controls the atomization core to stop heating; or, when the switch component is in the on state, the atomization device 100 controls the microphone to connect to the power supply / start the microphone, and when the switch component is in the off state, the atomization device 100 controls the microphone to disconnect from the power supply / turn off the microphone; or, when the switch component is in the on state, the first picture is displayed / the display screen is turned on, and when the switch component is in the off state, the second picture is displayed / the display screen is turned off; or, when the switch component is in the on state, the LED light is turned on, and when the switch component is in the off state, the LED light is turned off.

[0046] In this example, see Figures 5 and 6The switch assembly also includes a sliding member 30 and a push-pull portion 40. When the switch assembly is in the open state, the sliding member 30 contacts the elastic conductive member 20. The sliding member 30 is used to provide an extrusion stress that causes the elastic conductive member 20 to approach the circuit board 14, thereby controlling the contact and disconnection between the elastic conductive member 20 and the conductive contact 141. The push-pull portion 40 is used to operate the sliding member 30, and the push-pull portion 40 is detachably connected to the sliding member 30, which is convenient for later maintenance of the product.

[0047] For details about the on and off states of the switch components, please refer to Figure 5 When the push-pull part 40 is operated to move the sliding member 30 toward the direction close to the elastic conductive member 20, the sliding member 30 and the suspended end of the elastic conductive member 20 are in contact with each other, and an extrusion stress is applied, so that the suspended end of the elastic conductive member 20 is elastically deformed, close to the conductive contact 141 and in contact with the conductive contact 141, so that the circuit is turned on. At this time, the switch assembly is in the on state. Figure 6 When the push-pull part 40 is operated to make the sliding member 30 slide in the direction away from the elastic conductive member 20, the extrusion stress applied to the elastic conductive member 20 is cancelled. At this time, the elastic conductive member 20 is elastically reset and disconnected from the conductive contact 141, thereby shutting down the circuit. At this time, the switch assembly is in a closed state.

[0048] For further information, see Figures 5 to 8 The elastic conductive member 20 includes a spring body 22, which is a key part of the switch assembly to realize the circuit on-off function. The spring body 22 is bent, and the bending design increases the elasticity of the spring body 22. The bending part of the spring body 22 protrudes in the direction away from the sliding member 30 to form a contact area 21 for contacting the conductive contact 141. The spring body 22 includes a first sheet 221, a bent sheet 222 and a second sheet 223. The first sheet 221 is connected to the second sheet 223 through the bent sheet 222. The first sheet 221 and the second sheet 223 are arranged in parallel, so that the spring body 22 can evenly distribute stress when subjected to force, thereby improving durability. The first sheet 221 is fixedly connected to the circuit board 14 to ensure the stability of the electrical connection with the circuit board 14. The second sheet 223 is also provided with a contact area 21, which is used to contact the conductive contact 141.

[0049] Among them, see Figures 7 and 8The first sheet 221 is provided with a symmetrically arranged bending part 23 and a side surrounding part 24 on both sides of one end away from the bending sheet 222. The bending part 23 and the side surrounding part 24 are vertically connected to the first sheet 221 at one end close to the circuit board 14, which enhances the stability of the overall structure, can withstand greater external forces, and improves the durability of the structure. The bending part 23 is "L"-shaped, which can bear pressure and maintain a certain elasticity. The bending part 23 includes a vertical plate 231 and a horizontal plate 232. The vertical plate 231 is One end is vertically connected to the first sheet 221, the other end of the vertical plate 231 is vertically connected to the horizontal plate 232, and the other end of the horizontal plate 232 is vertically arranged and abutted with the other end of the side surrounding component 24. The structure is compact and stable, and the space utilization rate is improved. The bending component 23, the side surrounding component 24 and the first sheet 221 jointly form a limiting cavity 50, the second sheet 223 is penetrated in the limiting cavity 50 and extends to the outside of the limiting cavity 50, and the abutment area 21 is arranged on the side of the second sheet 223 extending to the outside of the limiting cavity 50.

[0050] Based on the above examples, please refer to Figure 5 , Figures 7 and 8 The second sheet 223 includes an elastic bending member 2231, which is connected to the bending sheet 222 through an elastic connector 2232. A first bending area 224 is provided at the connection between the elastic bending member 2231 and the elastic connector 2232. The first bending area 224 protrudes in a direction away from the circuit board 14. The protruding end of the first bending area 224 is in contact with the cross plate 232. The cross plate 232 plays a limiting role and provides an elastic stress opposite to the second sheet 223. This stress in the opposite direction can ensure that the circuit is in an off state when the sliding member 30 is not working, improve the stability of the switch assembly structure, and prevent the circuit from being accidentally turned on due to misoperation. An extrusion component 2233 is also provided at one end of the elastic bending member 2231 away from the elastic connector 2232. A second bending zone 225 is provided at the connection between the elastic bending member 2231 and the extrusion member 2233. The second bending zone 225 protrudes in a direction close to the circuit board 14. The resistance zone 21 is formed in the second bending zone 225. A third bending zone 226 is provided at one end of the extrusion member 2233 away from the second bending zone 225. This bending design enables the extrusion member 2233 to deform when being extruded, thereby transferring the extrusion stress to the second bending zone 225. The third bending zone 226 protrudes in a direction away from the circuit board 14. A resistance force point 227 is formed in the third bending zone 226. The resistance force point 227 is the direct action point for transmitting the extrusion stress. The extrusion action can be converted into the extrusion stress on the elastic bending member through the resistance force point 227, thereby realizing the control of the circuit on and off.

[0051] Furthermore, the elastic conductive part 20 includes but is not limited to beryllium copper stampings. The beryllium copper stampings have good conductive properties and sufficient elasticity to ensure that they can produce corresponding deformation when subjected to external force, thereby realizing the on-off control of the circuit. At the same time, the stamping process is used to manufacture the elastic conductive part 20, which not only improves production efficiency, but also reduces manufacturing costs, making the structure of the entire switch assembly more economical and practical.

[0052] See also Figure 5 , Figure 6 and Fig.10 A contact portion 31 is provided on one side of the sliding member 30 close to the elastic conductive member 20 and is vertically fixedly connected to the sliding member 30. The contact portion 31 contacts the elastic conductive member 20 when the switch assembly is in the on state, specifically, contacts the contact force point 227 formed on the third bending area 226 of the second sheet 223 in the spring sheet body 22 of the elastic conductive member 20. The contact portion 31 is used to transfer the extrusion stress to the elastic conductive member 20 to ensure the accuracy and stability of the switch operation.

[0053] For further information, see Figure 5 , Figure 6 , Fig. 9 and Fig.10 The push-pull part 40 is provided with an elastic snap-fitting part 41, and the push-pull part 40 is fixed to the sliding part 30 through the elastic snap-fitting part 41. The sliding part 30 is provided with a snap-fitting groove 34 for accommodating the elastic snap-fitting part 41. This snap-fitting method is not only simple and quick to assemble, but also convenient for disassembly and maintenance of the later structure, which improves the maintainability and service life of the product, reduces the maintenance cost, and improves the user experience. The elastic snap-fitting parts 41 are symmetrically arranged on both sides of the push-pull part 40, which enhances the connection stability between the push-pull part 40 and the sliding part 30, and ensures that the elastic snap-fitting parts 41 on both sides are symmetrically arranged on both sides of the push-pull part 40 when subjected to external force. The fastener 41 can be evenly stressed to avoid loosening or damage caused by uneven stress. A limit column 42 is provided between the two elastic fasteners 41, and a limit hole 35 compatible with the limit column 42 is opened on the sliding member 30. The setting of the limit column 42 further improves the connection strength between the push-pull part 40 and the sliding member 30, effectively preventing the shaking or falling off that may occur during use. In conjunction with the limit hole 35, the push-pull part 40 and the sliding member 30 are quickly positioned and installed, which improves the assembly efficiency and improves the overall performance and reliability of the electronic cigarette switch button structure.

[0054] Specifically, see Figure 5 The power module also includes a module housing 10, a mounting cavity 11 is provided in the module housing 10, a bracket 13 is provided in the mounting cavity 11, a sliding member 30 is slidably mounted on the bracket 13, and a guide groove extending along the axial direction of the module housing 10 is provided on the bracket 13. Fig.11The end of the sliding member 30 away from the push-pull portion 40 is provided with a guide slide limiter 32 adapted to the guide slide groove. The guide slide limiter 32 is used to guide the sliding member 30 to move smoothly along a predetermined path. The guide slide limiter 32 is embedded in the guide slide groove and slides with the guide slide groove. The setting of the guide slide groove provides a stable sliding track for the sliding member 30. The sliding cooperation between the guide slide limiter 32 and the guide slide groove enables the sliding member 30 to slide along the length direction of the guide slide groove, ensuring the stability and accuracy of the sliding member 30 during the movement process, making the switch operation more reliable. Please refer to Fig.10 , the sliding member 30 is also provided with limiting protrusions 33 on both axial sides, and the limiting protrusions 33 are used to provide precise limiting and stable support during the movement of the sliding member 30. The bracket 13 is also provided with limiting grooves corresponding to the limiting protrusions 33. This design enables the limiting protrusions 33 to be smoothly embedded in the limiting grooves during the sliding process of the sliding member 30, thereby locating and limiting the position of the sliding member 30, so that the resistance area 21 can be in stable contact with the conductive contact 141, ensuring that the circuit can be stably conducted for a long time, avoiding circuit interruption or instability caused by poor contact, and ensuring that users can obtain stable and safe circuit conduction effects while enjoying the atomization device.

[0055] Based on the above examples, please refer to Figure 2 , Figure 3 and Figure 5 The power module also includes a battery 1021. The mounting cavity 11 is also used to mount the battery 1021. The battery 1021 is used to provide electrical energy to ensure that the atomization device 100 can perform normal atomization operations. The bracket 13 also limits and fixes the battery 1021 to prevent poor contact caused by shaking and interruption of electrical energy supply. The circuit board 14 is used to control the connection and disconnection between the battery 1021 and the atomization module 101. Please refer to Figures 4 to 6 The module housing 10 is also provided with an installation slot 12, the push-pull portion 40 is arranged in the installation slot 12, and is detachably connected to the sliding member 30 through an elastic snap member 41, thereby ensuring normal switch operation.

[0056] See also Figures 1 to 3 The atomization module 101 includes an atomization shell 1011, an atomization core 1012 arranged in the atomization shell 1011, and a suction nozzle 1013 installed at one end of the atomization shell 1011 away from the power module 102. The atomization core 1012 is used to convert the liquid from a liquid state to a gas state. The suction nozzle 1013 is connected to the atomizer through an airway 1014. The suction nozzle 1013 is used to inhale the atomized steam, and the airway 1014 is used to transmit the atomized steam. The module shell 10 and the atomization shell 1011 together constitute a protective shell 200 of the atomization device 100.

[0057] In summary, the power supply module and atomization device 100 of the utility model, by adopting low-cost materials such as beryllium copper stampings to manufacture the elastic conductive part 20, combined with simple structural design and assembly process, significantly reduces the manufacturing cost of the switch component structure, while ensuring good conductivity and elasticity, and realizing a cost-effective product solution. The cooperation between the guide slide groove and the guide slide limiter 32 ensures that the sliding part 30 is not easy to deviate from the track during the sliding process, reduces operating errors, improves the stability and reliability of the switch operation, and provides users with a smooth use experience. The tight cooperation between the limit protrusion 33 and the limit groove allows the sliding part 30 to be in a specific position. The resistance area 21 and the conductive contact 141 can maintain stability, and the contact area 21 can be in firm contact with the conductive contact 141, effectively preventing poor contact or disconnection, ensuring stable conduction of the circuit, and improving the safety of the use of the electronic cigarette. The design of the elastic snap-fit ​​part 41 and the snap-fit ​​groove 34 makes the connection between the push-pull part 40 and the sliding part 30 firm and reliable, and easy to disassemble or replace, reducing the maintenance difficulty and cost, and improving the maintainability and service life of the product. Through the cooperation of the limiting column 42 and the limiting through hole, the push-pull part 40 and the sliding part 30 are accurately positioned and quickly installed, simplifying the assembly process, reducing assembly time and labor costs, and improving production efficiency.
