▎ 摘　　要

NOVELTY - Air purifier comprises a foreign matter filter unit, a photocatalyst filter unit (130) and a driving device for inflow and discharge of air. A photocatalytic filter (133) is arranged around a light source unit (134) installed at a center of a hollow housing (132). The photocatalyst filter unit has the photocatalytic filter arranged around the light source unit. A cover (131) has a through hole at the top of each filter so that air passes through the hollow part of each of the filters. The through hole is arranged on the cover so that a virtual line connected between the light source unit is not a single straight line without a bending point or bending point. The filter unit is made of liquid graphene and resin, which is prepared by preparing a solid or liquid form in which liquid graphene is dispersed in the resin. USE - The air purifier is useful in homes, and vehicles. ADVANTAGE - The air purifier secures air purifying power and antibacterial power by evenly irradiating light to the photocatalytic filter units mounted on the photo catalytic filter unit, so that the catalyst associated with the filter sufficiently participates in the reaction, thus maintaining the role of resin support, antibacterial and antifungal action in the foreign matter filter.
