Description

technical field

[0001] The invention relates to the field of automobile air purification, in particular to a positive and negative ion generator control circuit. Background technique

[0002] Most people usually work or rest indoors, and if indoor ventilation is poor, indoor decorations (leather, plastic, etc.), indoor smoking, indoor air-conditioning evaporators, etc., will cause indoor air to contain formaldehyde and benzene compounds. and other toxic gases; the pollution of people living in cities mainly comes from air pollution, floating solid particles (such as PM2. Nitrogen compounds), sulfur dioxide, TVOC, CO, bacteria, mites and other harmful substances enter the room through the external circulation; and because people are busy with work, they do not pay enough attention to the indoor air quality. Therefore, it is very important to sterilize the indoor air. Needed.

[0003] For the indoor environment, people often strengthen the ventilation of the room and regular...
