▎ 摘　　要

NOVELTY - Air purifying, sterilizing and virus inactivating device comprises a blower device (1), a deep UV light source (2), a photocatalysis light source (3), a graphene photocatalysis degradation device (4), a power source connection device (5) and a housing. The blower device, the deep UV light source, the photocatalysis light source and the graphene photocatalysis degradation device are all electrically connected to the power source connection device. The blower device, the deep UV light source, the photocatalysis light source, the graphene photocatalysis degradation device and the power source connection device are all fixedly connected to the housing. The deep UV light source and the photocatalysis light source are arranged together between the blower device and the graphene photocatalysis degradation device. The photocatalysis light source irradiates the graphene photocatalysis degradation device, and the housing is provided with a through-hole. USE - The device is useful in environment protection, functional composite material and photocatalytic fields. ADVANTAGE - The air purifying, sterilizing and virus inactivating device has high light catalytic efficiency material, which can realize food fresh-keeping storage and removing indoor harmful formaldehyde and various bacteria and virus at room temperature, further accelerate photocatalytic reaction, greatly increases hole number, and high electron mobility of graphene, effectively prolongs durability of carrier generated by photocatalytic, prevents hole and electronic composite, and further greatly improves high catalytic efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene photo-catalytic degradation device of air purifying, sterilizing and virus inactivating device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the air purifying, sterilizing and virus inactivating device.
