In addition, the working state of the heating element 151 can also be indicated by the brightness of the indicator light 203. For example, when the heating element 151 is activated, the light of the indicator light 203 becomes dim; when the heating element 151 stops working, the indicator light 203 returns to normal brightness.

In addition, in this embodiment, the bracket 22 in the power supply device 2 has a partition wall 2203 , and the partition wall 2203 divides the bracket 22 into an upper cavity 2202 located at the upper part and a lower cavity 2201 located at the lower part. The battery 23 is arranged in the lower chamber 2201, and the control assembly 202, the pneumatic switch 204, the air supply device 25, the indicator light 203, etc. are all arranged in the upper chamber 2202, so that the battery 23 is isolated from other components, and the battery 23 is abnormal when it is abnormal. Other components will not have an impact, which effectively avoids the potential safety hazard brought by the battery 23 itself.

In this embodiment, the power supply device 2 is not provided with the base 27 , the base 12 is directly arranged above the bracket 22 , and a ventilation gap 1202 is formed between the lower end surface of the base 12 and the upper end surface of the bracket 22 to atomize the The air inlet gap 210 formed between the outer wall surface of the appliance 1 and the inner wall surface of the power supply device 2 communicates with the ventilation hole 120 on the base 12 .

The atomizer 1 in this embodiment may further include a one-way valve 124 disposed on the annular boss 1211 . The inlet of the one-way valve 124 communicates with the vent hole 120 , and the outlet communicates with the air guide hole 1530 , so that the airflow can only flow from the vent hole 120 to the air hole 1530 in one direction.

It can be understood that the above technical features can be used in any combination without limitation.

The above examples only represent the preferred embodiments of the present invention, and their descriptions are more specific and detailed, but they should not be construed as limitations on the scope of the present invention; it should be noted that for those of ordinary skill in the art, in Under the premise of not departing from the concept of the present invention, the above-mentioned technical features can be freely combined, and some deformations and improvements can also be made, and these all belong to the protection scope of the present invention; therefore, all equivalent transformations made with the scope of the claims of the present invention All modifications and modifications shall fall within the scope of the claims of the present invention.
