▎ 摘　　要

NOVELTY - The dust box has a dust box structure (1) is square, round or semicircular shape, and the shape of the dust box structure matches the sweeper or vacuum cleaner. The dust box structure is provided with an air inlet (3), and the air inlet is directly connected with the suction duct. The upper part of the dust box is equipped with a lid that can open the dust box, and a first graphene sterilization filter (6) is installed inside the lid of the dust box. An air outlet (4) is provided on the other side of the air inlet of the dust collection box, and a second graphene sterilization filter (7) is installed in the air outlet box. The inner wall of the dust box is coated with a graphene sterilization layer to form a closed graphene elimination system for the dust box. USE - Graphene composite material sterilization and antibacterial sweeper and dust box for vacuum cleaner. ADVANTAGE - The dust box inhibiting or killing germs, making it simple, safe, efficient, and free of secondary pollution, solving the problem of germ killing in the dust box of sweepers or vacuum cleaners is an innovation in the use of graphene, which is easy to promote and use. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the structure of a dust box for a vacuum cleaner and a floor sweeper for sterilization and bacteriostasis of graphene composite material.
