When the control module 400 knows that there is airflow passing through the accommodating chamber 110, the heating power of the fumigation component 200 can be increased accordingly, and the fumigation component 200 heats the paste in the fumigation chamber 211 to atomize the paste into paste smoke, and the other airflow passes through the fumigation chamber 211, and carries the paste smoke to be discharged from the air inlet 120 to be inhaled by the user.

[0038] In addition, the control module 400 can also control the start or stop of the heating element 220 by controlling the switch module 500 .

[0039] In some embodiments of the present invention, the airflow detection and self-temperature regulating fumigator further includes an energy storage component 600 , which is connected to the input end of the switch module 500 to supply power to the heating component 220 .

[0040] The energy storage component 600 may be a battery or a supercapacitor. The control module 400 controls the switch module 500 to be turned on and off reasonably according to the airflow signal and adjusts the heating power of the heating component 220, thereby extending the power supply time of the energy storage component 600 and ensuring stable and reliable operation.

[0041] In some embodiments of the present invention, Figure 1 , 2As shown, the airflow detection and self-temperature regulating fumigator also includes a storage seat 610, which is detachably connected to the shell 100, and the energy storage component 600 is arranged in the storage seat 610. A detachable electrical connection structure 620 is provided between the storage seat 610 and the shell 100, and the energy storage component 600 is connected to the input end of the switch module 500 through the electrical connection structure 620.

It should be noted that the air inlet 130 located at the bottom of the shell 100 can be relatively small, such as the assembly gap between components. After flowing through the airflow detection module 300 and the ventilation gap, it is discharged from the air inlet 120. This structure enables the airflow to carry more paste smoke to meet the user experience.

[0048] A conductive circuit layer is provided on the circuit board 700, and the output end of the switch module 500 can be connected to the ejector pin 820 through the conductive circuit layer, and the ejector pin 820 then conducts the electrical energy to the fumigation assembly 200, with a compact structure.

[0049] In some embodiments of the present invention, Figure 3 As shown, the airflow detection and self-temperature regulating fumigator also includes a top cover 900, which is detachably connected to the shell 100 so as to be able to open or close the accommodating cavity 110, and the air inlet 120 and the air inlet 130 are both provided on the top cover 900.
