Bipolar Ionizer for Air Purification and Diffuser Using Bipolar Ionizer

摘要

The present invention relates to an ionizer, and more particularly to an alternating current bipolar ionizer for air purification. The ionizer of the present invention has a plate-like structure composed of a substrate having a thermally conductive sheet, a porous emitter plate, a dielectric barrier plate, and a porous ground plate with an ion extraction mechanism, all of which are sequentially stacked. According to the above technical solution, a ground plate having an ion extraction structure and an emitter plate form an electric field of a precise size, and electrons of the emitter plate are induced in the dielectric barrier plate on the ground side of the electric field. Some of the electrons meet the ground plate and flow to the ground plate to form an electric current, and some of the electrons escape and meet the indoor air molecules. When the ejected electrons reach a certain percentage, the oxygen molecules are excited and converted to an ionic state, improving air quality. When AC high voltage current is input, the anode ions are generated alternately, so that the anode ionized gas flow can be injected into the air, effectively improving the air quality.
