The oil cup shell 11 of the atomization module 10 is provided with a storage cotton 110 for storing atomization liquid, and the atomization liquid is heated and atomized by the atomization core 12 to form an aerosol.

[0045] It can be understood that the positioning needle 220 and the positioning blind hole 130 cooperate to position the atomization module 10 and the power supply module 20, simplifying the assembly process of the two. Specifically, in this embodiment, the positioning needle 220 and the positioning blind hole 130 are arranged in two groups.

[0046] It can be understood that when the atomization device 1 works, the condensate generated inside generally flows downward and collects, the hole of the positioning blind hole 130 is open at one end of the power supply module 20 and closed at the other end, and such a design can effectively prevent the condensate from flowing into the positioning blind hole 130, reducing the risk of the condensate eroding the positioning needle 220 and the circuit board 22.

[0047] It can be understood that the positioning blind hole 130, the wire outlet hole 131 and the airflow hole 132 are independently arranged, so that there is physical isolation between the circuit part of the atomization device 1 and the airflow path, which can ensure that the generated condensate can stay in the airflow hole 132 and not enter the wire outlet hole 131 and the positioning blind hole 130, effectively reducing the opportunity of the wire 121 contacting the airflow, and further reducing the influence of the condensate on the internal devices.

[0048] It can be understood that the upper and lower ends of the oil cup shell 11 are further provided with upper and lower sealing members 111 and 112 to strengthen the sealing of the oil cup shell 11 and prevent the internal stored atomization liquid from overflowing.

[0050] It can be understood that, Figure 5 and Figure 6 The atomization module 10 and the power supply module 20 have not been completely matched, and when the atomization module 10 continues to connect with the power supply module 20 downward, the positioning needle 220 will fully contact the wire 121 which turns back into the positioning blind hole 130, ensuring reliable connection of the wire 121 and the circuit board 22.

[0051] It can be understood that the circuit board 22 is arranged in the support shell 21, and the connection of the wire 121 and the circuit board 22 needs to pass through the support shell 21. This design can avoid opening a through hole for the wire 121 to pass through on the support shell 21, and the positioning blind hole 130 has better sealing performance than the through hole, so that the influence of the condensed liquid on the wire 121 and the circuit board 22 and the like can be further reduced.

[0052] It can be understood that when the wire 121 is electrically connected with the circuit board 22 through the positioning needle 220, the positioning needle 220 should be arranged of a conductive material.

[0053] Please continue to refer to Figure 4 The docking support 13 is provided with a groove 133 between the positioning blind hole 130 and the wire outlet hole 131.

[0054] It can be understood that after the wire 121 passes out of the wire outlet hole 131, the wire 121 can be folded back into the positioning blind hole 130 through the groove 133. The design of the groove 133 not only makes the positioning blind hole 130 and the wire outlet hole 131 have better sealing performance relative to the airflow hole 132, but also reduces the abrasion and compression of the wall between the positioning blind hole 130 and the wire outlet hole 131 on the wire 121. Therefore, the design of the groove 133 improves the reliability of the equipment.

[0055] It can be understood that the wire 121 can be further fixed in the groove 133 by an adhesive, so as to ensure that the wire 121 will not be separated or deviated due to external vibration, or damaged due to disassembly, and the overall reliability is improved. It should be understood that other ways other than the adhesive can be used to fix the wire 121, such as a buckle 135 and the like.

[0057] It can be understood that the partition plate 210 isolates the atomization module 10 and the power supply module 20 to a certain extent, so as to reduce the risk of adverse effects between the two.

[0058] It can be understood that the microphone 221 is used to sense the change of air pressure, and then control the start and stop of the atomization device 1. The microphone air hole column 211 is used to finely adjust the air flow entering the microphone 221, and ensure that the microphone 221 can sense the change of internal air pressure, so as to generate a suitable electrical signal, and then control the start and stop of the atomization device 1. The main air hole column 212 is the main air inlet of the whole atomization device 1, which is used to introduce external airflow to drive the aerosol generated by the atomization module 10 to flow outward, and ensure smooth airflow.

[0059] It can be understood that the microphone air hole column 211 and the main air hole column 212 are independently designed, and the air flow of the two parts can be adjusted respectively to prevent air flow interference and ensure the accuracy of the work of the microphone 221.
