Operating Principle:
Plasma sterilization refers to: utilizing the plasma generator 4 to enable the ionization apparatus 5 to generate plasma, utilizing the active particles such as high energy electrons, free radicals and the like to react with a pollutant in the air, such that pollutant molecules are decomposed in a very short time, thus achieving the objective of air purification by means of subsequent various reactions.
Negative ion sterilization refers to: utilizing the negative ion generator 7 to generate negative air ions, wherein the negative air ion is formed by adding a pair of free electrons to an oxygen molecule, and carries negative charges, thereby having an extraordinary binding ability; gathering dusts, vapor, bacteria, and viruses which float in a house and generally carry positive charges together, such that the dusts, vapor, bacteria, and viruses lose the ability of freely floating in the air and quickly fall down, so as to purify the air and the environment.
Ultraviolet sterilization refers to: utilizing ultraviolet radiation to photolyze and denature bacteria protein, and destroying the amino acid, nucleic acid and enzyme to sterilize the bacteria. Furthermore, when the ultraviolet passes through the air, the oxygen in the air is ionized to generate ozone, thereby enhancing the sterilization effect.
The present invention uses the above three methods to sterilize bacteria and viruses suspending in the air, generates plasma according to a point discharge principle so as to purify the dusts and pathogenic bacteria suspending in the air, and can effectively inhibit the breeding of pathogenic bacteria in a public place; the fan 9 and the circulation air duct 10 enable a great deal of treated clean air to quickly circulate and flow in a house; furthermore, the cabinet 1 can be utilized to mount the lamp at the top of an indoor space, and the light source mechanism under the cabinet 1 illuminates the space, thereby overcoming the defect that an air purifier or an ultraviolet sterilization lamp cannot be mounted due to the limited indoor space, and achieving the effect of diversified use functions.
