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 using the pneumatic switch and an electronic cigarette, the pneumatic switch comprises a main body, a triggering assembly and a flexible protective film, the main body is provided with an accommodating cavity, and a first cavity wall of the accommodating cavity is provided with an air outlet hole communicated with the outside; the protective film is arranged in the accommodating cavity and is arranged between the triggering assembly and the first cavity wall so as to divide the accommodating cavity into a first cavity body and asecond cavity body in an airtight manner; the triggering assembly is accommodated in the first cavity and is triggered in a negative pressure state; and when the gas in the second cavity is pumped out, at least part of the protective film deforms towards the second cavity, so that part of the gas flow in the first cavity flows into a space generated by deformation of the protective film. According to the technical scheme, the phenomenon that the sensor is damaged due to the fact that tobacco juice and condensate water permeate into the sensor is effectively prevented.

Description

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