Bipolar ion generator for air purification and diffuser using bipolar ion generator

摘要

The invention relates to an ion generator, in particular to an alternate bipolar ion generator for air purification. The iron generator is a plate structure formed by sequentially stacking a substrate having a thermally conductive sheet, a porous emission polar plate, a dielectric barrier plate, and a porous grounding polar plate having an ion extraction mechanism. By using the technical solution above, the grounding pole piece having an ion extraction structure and the emission pole piece form an electric field having precision dimensions, said electric field extracts, at a grounding side of the electric field, the electrons of the emission pole piece out of the dielectric barrier plate; some of the electrons meet the grounding polar plate and flow into same, so as to form a current, and some of the electrons escape from a medium surface and meet the indoor air molecules, and the escaped electrons motivate, when reaching a certain rate, the oxygen molecules into an ionic state, improving the air quality. When a high voltage alternating current is inputted, bipolar ions are generated alternatively, thereby being able to inject bipolar ion airflow into the air, effectively improving the air quality.
