Abstract

The invention discloses an alternating current noise-eliminating negative ion generator. The alternating current noise-eliminating negative ion generator is characterized by mainly comprising a transformer T2, a control chip U3, a triode VT1, a discharging terminal E, a potentiometer R3 and the like, wherein the potentiometer R3 is connected between the b end and the f2 end of a gas sensitive sensor. The alternating current noise-eliminating negative ion generator can generate negative ions automatically according to the concentration of harmful gas in a room, is very high in sensitivity and can effectively purify air in the room; meanwhile, the sensitivity can be adjusted according to needs, so that the generator can be applicable to different occasions; and in addition, the negative iongenerator has an overvoltage protection function and can cut off a power supply automatically in case of an overvoltage, thereby protecting electronic components from damage by the voltage.

Description

technical field

[0001] The invention relates to the field of air purification, in particular to an AC noise eliminating negative ion generator. Background technique

[0002] In recent years, the widespread use of air conditioners and computers and the prevalence of building decoration have led to the deterioration of indoor air quality. Toxic and harmful gases and suspended solids exceed the standard, but healthy negative ions are seriously lacking, resulting in an increase in the incidence of diseases and a decrease in work efficiency. In order to improve air quality, various air purification technologies and equipment have emerged, including negative ion generators. The negative ion generator detects the concentration of harmful gases in the indoor air, and when the concentration of harmful gases is too high, it will automatically start to generate negative ions, so as to achieve the purpose of fresh air. Yet the sensitivity of present negative ion generator is not high,...
