In order to improve the air in the living environment and improve air quality, people adopt various methods to kill germs in the air and eliminate harmful substances to reduce air pollution. At present, the main methods to improve air quality are: 1. Air filtration method, which is composed of fan, primary effect, medium effect, high efficiency (sub-high efficiency) filter, etc. The filter material is mainly glass fiber, synthetic fiber, asbestos fiber and Filter paper or filter cloth made of these fibers is used to filter the dust in the air to purify the air, but these porous filter materials will increase the resistance to air flow, and as the use time prolongs, its filtering effect will decrease. If it is not replaced in time, it will aggravate air pollution and even cause secondary pollution; (2) Electrostatic precipitator method, by discharging the circulating air, the dust in the air is charged, and then the dust collecting device is used to collect the charged dust Ash, to achieve the purpose of purifying the air, but this method cannot kill the germs in the air, and it is inconvenient to use; (3) Ultraviolet sterilization method: use ultraviolet rays to kill germs in the air, but this method cannot filter the germs in the air Dust cannot purify the air, and it is difficult to install and use it in the central air-conditioning system; (4) Plasma purification method, through the strong electric field and gas discharge generated by the plasma generator, the water molecules and gas molecules in the air are ionized, and after a A series of complex excitation, dissociation and ionization processes produce extremely active free radicals such as .OH, .H, and .O, which undergo a series of complex redox reactions with pollutants in the air, in which volatile organic compounds are decomposed , thereby achieving the purpose of air purification, these free radicals also have a strong inactivation effect on microorganisms, and achieve the purpose of sterilization while eliminating organic pollution, but the structure of the existing plasma generator or plasma purification device All are relatively complicated, and the density of the generated plasma is small, the air purification speed is slow, and the sterilization and purification effect is not ideal. In addition, the existing indoor air purifiers are often only used to eliminate pollutants in the indoor air, and due to the limitation of indoor environmental conditions, the indoor air is often too dry most of the time. Long-term drying not only makes people feel uncomfortable, but also It will also lead to the increase of suspended particles and bacteria and viruses in the air, affecting people's quality of life and health.
