▎ 摘　　要

NOVELTY - The assembly has a copper oxide sterilizing cloth (1), a graphene sterilizing filter cloth (2), an activated carbon filter cloth (3) and a composite sterilizing cotton (4) that are fixedly connected on an inner wall of a sterilizing machine air inlet passage (10) and orderly arranged along an air inlet direction. The graphene sterilizing filter cloth is provided with a sterilizing and inhibiting bacteria. USE - The composite sterilizing filter assembly is used for air inlet of sterilizing machine. ADVANTAGE - The copper oxide sterilizing cloth can effectively filter coronavirus in the inactivated air inlet. The graphene sterilizing filter cloth has the function of sterilizing and inhibiting bacteria again. The activated carbon filter cloth can absorb the dust and peculiar smell in the air. The composite sterilizing cotton can sterilize and inhibit the various virus bacteria in the air, and greatly improves the sterilizing effect of the sterilizing machine. DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of the composite sterilizing filter assembly.
