▎ 摘　　要

NOVELTY - The air purification module comprises a fan, filtering and adsorption device, light source unit, and light source. The light source is used to provide UV light to the filter adsorbent device, where the light source device comprises composite photocatalytic material and a filter net. The photocatalyst material is arranged in the filter net, and comprises titanium dioxide and graphene. The weight percentage of graphene is 3-5 wt.% of titanium dioxide in the photocatalyst material. USE - Air purifying module for use in a refrigerator for refrigerating and storing food and a cold air supply device for supplying cold air to the storage chamber. ADVANTAGE - The weight percentage of 3-5 graphite alkene of TiO2 and graphene composite photo-catalytic material combined with 200-200 nm UV light, can realize killing microorganism, remove of organic matter, and purify the refrigerator to the largest extent. The filtering and absorbing device has the function of enriching and filtering the microorganisms and peculiar smell, so it purifies the refrigerator. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a refrigerator. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the air purification module.
