[0002] At present, there are three main working modes of air purifiers on the market: filtering, electric purification, and filtering-electric purification combined. Among them, the electric purification purifier uses the generating electrode to ionize the air, so that the particles in the air are charged; then the charged particles will be adsorbed on the collecting electrode with opposite charge or zero voltage, thereby achieving the purpose of dust collection and purification.
