[0028] Operating Principle:

[0029] 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.
