Air conditioning and purification sterilizer

The utility model relates to an air-conditioning, purifying, disinfecting and sterilizing device which is used for purifying, sterilizing and disinfecting the air in the ventilation ducts of the air-conditioning. The device is a square body composed of a plurality of stainless steel plates. An active oxygen generator and an anion generator are arranged in the square body. A high-concentration active oxygen area is arranged between the active oxygen generator and the anion generator. A plate-type positive electrode plate and an acicular negative electrode plate are arranged on the left frame and the right frame. A high-frequency high-voltage power supply is connected with the active oxygen generator and the anion generator respectively to form high voltage discharge which generates electron beams as a first barrier to kill bacterium. Meanwhile active oxygen comes into the high-concentration active oxygen area with the wind to sterilize and disinfect. The rest viruses and bacterium are killed completely by the active oxygen barrier of the anion generator. Large numbers of anions generated by the anion generator are combined with the active oxygen to prevent secondary pollution. The rest anions enter the room with the air to create a healthy room which is suitable for the human survival.
