Photocatalytic self-cleaning air circulation sterilization device

Abstract

This utility model discloses a photocatalytic self-cleaning air circulation sterilization device, including a sterilization chamber and a circulation sterilization mechanism installed on the upper part of the sterilization chamber. An air duct is installed on the upper part of the inner wall of the sterilization chamber, and a photocatalytic sterilizer body is inserted into the top of the sterilization chamber. A bent pipe is inserted into the other side of the outer wall of the sterilization chamber, and a second conduit is inserted into the lower edge of the other side of the sterilization chamber. A first fan is installed on the inner wall of the first mounting plate. This utility model continuously draws indoor air into the sterilization chamber through the first fan below, and guides it into the air duct through the first conduit and the bent pipe, allowing it to contact the photocatalytic sterilizer body to achieve photocatalytic self-cleaning sterilization. Finally, the air is discharged back into the room through the exhaust pipe, achieving indoor air circulation sterilization. Simultaneously, the second conduit exchanges indoor and outdoor air, ensuring that the air discharged outdoors is also sterilized, improving the sterilization effect of the equipment and reducing the risk of bacterial infection for indoor and outdoor personnel.
