Abstract

The invention discloses an AC noise elimination negative ion generator, which is characterized in that: a transformer T2, a control chip U3, a triode VT1, and a discharge terminal E are connected in series to the electric potential between the b end and the f2 end of the gas sensor Q device R3 and so on. The invention can automatically generate negative ions according to the harmful gas concentration in the room, has high sensitivity, and can effectively purify indoor air; meanwhile, the invention can adjust the sensitivity according to requirements, so that the invention can be applied to different occasions. The invention has an overvoltage protection function, and can automatically cut off the power supply when an overvoltage occurs, so as to protect electronic components from being damaged by the overvoltage.

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,...
