Pneumatic sensor based on friction power generation, airflow treatment device, and electronic cigarette

Abstract

The invention discloses a pneumatic sensor based on friction power generation. The internal of a housing is provided with a holding cavity, and a side wall is provided with an air inlet, and a bottom wall is provided with an air outlet. The air inlet and the air outlet are communicated with the holding cavity, to form an airflow channel. Two ends of a vibrating diaphragm assembly are fixedly arranged in the holding cavity in the housing, and vibration gaps are formed between the vibrating diaphragm assembly and an electrode assembly and the bottom wall of the housing. Driven by the internal airflow of the holding cavity, the vibrating diaphragm assembly vibrates in a reciprocating manner relative to then electrode assembly and the bottom wall of the housing. The electrode assembly is a signal output end of the pneumatic sensor, and is oppositely arranged with the vibrating diaphragm assembly. The reciprocating vibrating diaphragm assembly rubs with the electrode assembly and / or the bottom wall of the housing, to generate a sensing electric signal, and the signal is output by the electrode assembly. The invention also discloses an airflow treatment device and an electronic cigarette. The pneumatic sensor based on friction power generation, the airflow treatment device, and the electronic cigarette are simple in structure and manufacturing process, good in anti-interference performance, and good in stability.

Description

technical field [0001] The invention relates to the field of friction power generation, in particular to a pneumatic sensor, an airflow processing device and an electronic cigarette based on friction power generation. Background technique [0002] E-cigarettes are also called electronic cigarettes and virtual cigarettes. They have a similar appearance and taste to traditional cigarettes, and can also suck out smoke like traditional cigarettes. In addition, some e-cigarettes can also add various flavors such as mint according to the user's personal preference. [0003] With the continuous development of people's living needs, more and more people choose to use e-cigarettes instead of traditional cigarettes because e-cigarettes do not have other harmful components such as tar and suspended particles in traditional cigarettes, and some people also use e-cigarettes to quit smoking. [0004] However, the existing sensors used in electronic cigarettes have complex structures and ...

Problems solved by technology

[0004] However, the existing sensors used in electronic cigarettes have complex structures and manufacturing processes, high manufacturing costs, and high requirements for external signal processing modules. They are also prone to false triggering by external vibrations and poor working stability.
