Abstract (en)
The present utility model discloses an air pressure switch, a power supply device using this air pressure switch, and an electronic cigarette using this power supply device. The air pressure switch includes a main body that includes a sensing area that will be triggered under negative pressure. The air pressure switch further includes an flexible protection film installed on the main body and at least the outer surface of the main body where sensing area is provided so that a first cavity is enclosed by the protective film and the surface of the main body where the sensing area is provided and formed. The protective film deforms away from the main body under the external suction force, so that the airflow in the first cavity can partially flow into the space generated by the deformation of the protective film.
