When gas flows in the gas flow channel 15, the first film 141 and the second film 142 move relative to each other, the two layers of materials with different electronegativities rub against each other under the change of gas flow to generate static electricity, and the static electricity induces charges on the two opposite surfaces of the static friction film 14 to generate a control signal.
The circuit board 13 is provided with a controller 134, and the controller 134 is electrically connected to the two back surfaces of the first film 141 and the second film 142 to receive a control signal generated by the airflow variation detected by the electrostatic friction film 14.
