The wrapping member 240 is made of plastic. When the power supply connection member 220, the communication connection member 230, and the chip 250 are all provided on the first circuit board 210 to form an assembly, the assembly can be placed into an injection mold, and molten plastic liquid is injected into the injection mold by an injection molding machine, and the cooled plastic liquid will be formed into the wrapping member 240. When the wrapping member 240 is formed, the first circuit board 210 will be inserted in the wrapping member 240, and only a part of the power supply connection member 220 and the communication connection member 230 are located outside the wrapping member 240, while the chip 250 can be completely located inside the wrapping member 240. By providing the wrapping member 240, harmful substances can be prevented from entering the first circuit board 210 and the chip 250, thereby forming a good protection effect on the first circuit board 210 and the chip 250, and ensuring the conductive stability of the power supply connection member 220 and the information transmission stability of the communication connection member 230.

During an injection molding process of the wrapping member 240, the molten plastic liquid can be injected into the injection mold by a screw injection machine with a preset pressure and maintain a certain injection speed and time, so that the molten plastic liquid can fill the entire cavity of the injection mold in a short time, and defects such as cracks or holes can be avoided in the molded wrapping member 240. Then, holding pressure is maintained for a certain period of time, which can effectively eliminate the influence caused by a volume reduction of the wrapping member 240, so that the new molten plastic liquid can quickly fill the reduced space of the wrapping member 240, and ensure the molding quality of the wrapping member 240. Of course, the holding pressure can be performed in multiple stages, and different holding pressures are used in different stages, so that a residual internal stress generated in the wrapping member 240 can be effectively released, and a mechanical strength of the wrapping member 240 can be improved. Finally, the molten plastic liquid may be cooled by water cooling or furnace cooling to form a solid wrapping member 240, and then the injection mold is opened to take out the coating member 240. Of course, before injecting the solution plastic liquid, the cavity of the injection mold and the assembly as a whole may be preheated, so as to reduce the temperature difference between the cavity of the injection mold and the molten plastic liquid, avoid the assembly as a whole from warping to different degrees under the action of thermal expansion and cold contraction, and finally ensure a size accuracy of the coating member 240 after molding.

Referring to FIGS. 5, 6 and 9, in some embodiments, the power supply assembly 12 includes a battery 300 and a second connection unit 400 electrically connected to the battery 300. The battery 300 can supply power to the second connection unit 400. Specifically, the second connection unit 400 includes a second circuit board 410, a plurality of clamping members 420, a mounting housing 430, and a second elastic sheet 440. The second circuit board 410 is electrically connected to the battery 300, and the clamping members 420 are electrically connected to the second circuit board 410. The mounting housing 430 has an abutting surface 433, and the mounting housing 430 includes two or more protruding columns 432. One end of the protruding column 432 is fixedly connected to the abutting surface 433, and the other end of the protruding column 432 protrudes from the abutting surface 433 by a certain height. The second circuit board 410 can be provided with a through hole, and the protruding column 432 can extend through the through hole. Meanwhile, a surface of the second circuit board 410 abuts against the abutting surface 433, for example, the surface of the second circuit board 410 is directly attached to the abutting surface 433, so that the second circuit board 410 and the mounting housing 430 can be fixedly connected.

Referring to FIG. 9 and FIG. 10, the clamping member 420 is provided on the mounting housing 430. Each clamping member 420 includes two first elastic sheets 402 opposite to each other. The mounting housing 430 is provided a mounting groove 431, and each first elastic sheet 402 includes a first protrusion 421 located in the mounting groove 431. The two first protrusions 421 on the same clamping member 420 are spaced apart along a thickness direction of the mounting housing 430. The first protrusions 421 on all the clamping members 420 are arranged to form two rows, and the two rows of first protrusions 421 are also spaced apart along the thickness direction of the mounting housing 430. During the entire connection process of the atomizer 11 and the power supply assembly 12, the first connection unit 200 can be detachably connected to the second connection unit 400. Specifically, the first circuit board 210 is inserted into the mounting groove 431 of the mounting housing 430, and the first elastic sheets 402 of all the clamping members 420 clamp the first circuit board 210 through the first protruding portions 421, so that the first circuit board 210 is detachably sandwiched between the first elastic sheets 402 of all the clamping members 420. At the same time, two first protrusions 421 of two clamping members 420 abut against the power supply sheets 222 of two power supply connection members 220, respectively, and the first protrusions 421 of other clamping members 420 abut against the communication sheets 231 of different communication connection members 230, respectively. For the two first protrusions 421 on the same clamping member 420, one of the first protrusions 421 abuts against the communication sheet 231 on the first surface 211 of the communication connection member 230, and the other first protrusion 421 abuts against the communication sheet 231 on the second surface 212 of the communication connection member 230, so that the transmission of communication information between the first elastic sheet 402 and the communication connection member 230 can be achieved.

When the first protrusion 421 of the first elastic sheet 402 abuts against the power supply sheet 222, the battery 300 can provide electrical energy for the atomizing core 100 through the first elastic sheet 402, the power supply sheet 222, and the power supply post 221 in sequence. When the first protrusion 421 of the first elastic sheet 402 abuts against the communication sheet 231, the communication information can be transmitted between the communication sheet 231 and the first elastic sheet 402 abutting against the communication sheet 231. For example, the transmitted communication information may be parameter information such as viscosity of the e-liquid in the atomizing core 100, resistance value of the heating wire of the atomizing core 100, and material of the heating wire. By transmitting the communication information, the battery 300 may output appropriate power. Therefore, the atomization speed and concentration of the e-liquid in the atomizing core 100 can be reasonably adjusted.

The two first elastic sheets 402 of the same clamping member 420 form a parallel circuit. With the same first elastic sheet as a reference, when the first circuit board 210 is inserted in the mounting groove 431, the first surface 211 of the first circuit board 210 faces the first elastic sheet 402, and at this time, the first circuit board 210 forms a "forward insertion". When the first circuit board 210 is inserted in the mounting groove 431, the second surface 212 of the first circuit board 210 faces the first elastic sheet 402, and the first circuit board 210 forms a "reversed insertion". Since the two first elastic sheets 402 form a parallel circuit, no matter whether the first circuit board 210 is inserted in a "forward insertion" or a "reversed insertion", the transmission of the electrical energy and the communication information between the first connection unit 200 and the second connection unit 400 will not be affected, thereby ensuring the stability of power supply or communication.

The first elastic sheet 402 further includes an insertion portion 423 located outside the mounting housing 430. The second circuit board 410 may also be provided with a through hole, the insertion portion 423 extends in the through hole, so as to realize an electrical connection between the first elastic sheet 402 and the second circuit board 410. All the insertion portions 423 of all the clamping members 420 are arranged in two rows, the two rows of the insertion portions 423 are spaced apart in a direction perpendicular to the thickness direction of the mounting housing 430. By providing above configuration, the orderly connection between all the first elastic sheet 402 and the second circuit board 410 can be achieved, and the stability of the first elastic sheet 402 in power supply or communication can be ensured.

The first elastic sheet 402 is further provided with a latching groove 422, and the latching groove 422 is wrapped in the mounting housing 430. When the first elastic sheet 402 is connected to the mounting housing 430, the latching groove 422 can form a cooperation relationship with a structure in the mounting housing 430, and an interference effect formed by the cooperation relationship can effectively prevent the first elastic sheet 402 from being pulled out from the mounting housing 430, thereby improving the mounting stability of the first elastic sheet 402 and further ensuring the stability of the first elastic sheet 402 in power supply or communication.

Two second elastic sheets 440 are provided, and the two second elastic sheets 440 are both connected to the mounting housing 430. The two second elastic sheets 440 are spaced apart along a width direction of the mounting housing 430, so that all the clamping members 420 are located between the two second elastic sheets 440. The second elastic sheet 440 has a second protrusion 441 located in the mounting groove 431 of the mounting housing 430, and two second protrusions 441 are provided opposite to each other. The first circuit board 210 is provided with recesses 214, two recesses 214 are provided, which are corresponding to the second protrusions 441. When the first circuit board 210 is inserted in the mounting groove, the second protrusion 441 is engaged with the recess 214. Due to the interference effect formed by the cooperation relationship, the stability of the first circuit board 210 can be further improved.

Therefore, by detachably sandwiching the first circuit board 210 between the two first elastic sheets 402 of each clamping member 420, a detachable connection between the entire atomizer 11 and the power supply assembly 12 can be achieved, and additional magnets for magnetic connection and additional related structures for snap connection are omitted, so that the structure of the entire electronic atomization device 10 can be simplified. At the same time, when the first elastic sheets 402 on part of the clamping members 420 abut against the power supply connection member 220, the battery 300 can supply power to the atomizing core 100 through the first elastic sheet 402 and the power supply connection member 220, so that the atomizing core 100 can atomize the e-liquid. Moreover, when the first elastic sheets 402 on the other part of the clamping members 420 abuts against the communication connection member 230, the transmission of communication information between the entire atomizer 11 and the power supply assembly 12 can be achieved, so that the power supply assembly 12 can adjust the atomization effect of the e-liquid in the atomizing core 100. Therefore, through the connection of the first connection unit 200 and the second connection unit 400, the electrical connection and the communication connection between the atomizer 11 and the power supply assembly 12 can be simultaneously realized on the basis of simple structure, so as to ensure the diversification of the functions of the power supply assembly 12. Furthermore, the second elastic sheet 440 cooperates with the recess 214 to further improve the stability of the mechanical connection between the atomizer 11 and the power assembly 12, thereby improving the stability of the electrical connection and the communication connection.
