Pneumatic switch of electronic cigarette, power supply device of electronic cigarette and electronic cigarette

Abstract

The invention discloses a pneumatic switch, a power supply device applying the pneumatic switch and an electronic cigarette applying the power supply device. The pneumatic switch of the electronic cigarette comprises a main body, the main body is provided with an induction area; the induction area is triggered when in a negative pressure state, and the pneumatic switch is characterized in that thepneumatic switch further comprises a flexible protective film, the protective film is installed on the main body, and at least the outer surface, provided with the induction area, of the main body iscovered in a sealed mode, so that a first cavity is defined by the protective film and the surface, provided with the induction area, of the main body; and the protective film departs from the main body and deforms under the action of external suction force, so that airflow in the first cavity partially flows into a space generated by deformation of the protective film. According to the technicalscheme, smoke liquid and condensate water are effectively prevented from permeating into the pneumatic switch and damaging the pneumatic switch.

Description

technical field [0001] The invention relates to a pneumatic switch of an electronic cigarette, a power supply device of the electronic cigarette using the pneumatic switch, and an electronic cigarette using the power supply device. Background technique [0002] With the gradual development of the electronic cigarette industry, small electronic cigarettes are more and more popular among consumers. In order to reduce the volume of the product, a pneumatic switch is usually used to trigger the user's suction, so that the electronic cigarette atomizes the stored liquid into smoke for the user to smoke. Suck. [0003] However, the pneumatic switch needs to be connected to the airway of the electronic cigarette to be triggered when the user inhales. During the long-term smoking process, the stored smoke liquid and the condensed water generated during the atomization process will accumulate in the electronic cigarette cavity, and the surface of the pneumatic switch of the electron...

AI Technical Summary

Problems solved by technology

During the long-term smoking process, the stored smoke liquid and the condensed water generated during the atomization process will accumulate in the electronic cigarette cavity, and the surface of the pneumatic switch of the electronic cigarette is usually equipped with a dustproof cloth, which is easy to absorb the smoke liquid and condensed water , resulting in reduced sensitivity, and even short-circuit damage
