Description
Technical Field
[0001] The utility model belongs to the technical field of air purification, and particularly relates to a high-voltage corona discharge plasma generating device. Background Art
[0002] Air purification devices widely used in indoor places are usually air purification filters. This method of purifying air by adsorbing impurities through a filter screen has limited purification effect and cannot achieve the functions of sterilization and deodorization. The positive ions and negative ions simultaneously generated by the plasma generator release a huge amount of energy instantaneously during the positive and negative charge neutralization in the air, resulting in the death of surrounding bacteria, achieving the sterilization effect. At the same time, since the number of negative ions is greater than that of positive ions, the excess negative ions floating in the air play the roles of dust removal, deodorization, eliminating odors, and improving air quality.
