Effect.
When the plasma of generation includes：When positive polarity plasma and negative polarity plasma, the positive polarity plasma
Body and negative polarity plasma can be transported on the flabellum of fan under the drive for the negative pressure that fan rotation generates, and work as flabellum
When the electrostatic charge on surface is negative electrical charge, which can attract positive polarity plasma, when the electrostatic charge of blade surface is
When positive charge, which can attract negative polarity plasma, to make the electrostatic charge of blade surface be neutralized, can reach
Eliminate the purpose of electrostatic, and then eliminate the adhesive force to bacterium and dust that is generated by electrostatic, to solving due to bacterium and
Dust is attached to a series of problems caused by blade surface.Also, the positive polarity plasma and the mixing of negative polarity plasma
When, chemistry can occur for the positive corpusc(u)le group of positive polarity plasma composition and the negative population of negative polarity plasma composition instead
It answers, generates hydroxyl radical free radical (OH) or hydrogen peroxide H2O2Isoreactivity substance, the active material can change the molecular structure of bacterium
Or energy conversion is carried out to it, to play the effect of sterilization.
