Air purifier with improved purification efficiency

摘要

The present invention relates to an air purification apparatus with improved purification efficiency and, more specifically, to an air purification apparatus capable of discharging air purified through sterilization using a UV lamp. The air purification apparatus includes: a body part (100) comprising a first plate (110) including an outlet (111) penetrating one side to discharge purified air, and a second plate (120) placed to correspond to the first plate (110) and including an inlet (121) penetrating to suck outside air; and a purification part (200) comprising a fixed body (210) including an insertion hole (211) formed to penetrate the inside and having both sides placed on the same line as the outlet (111) and the inlet (121) to be connected with the first and second plates (110, 120) respectively, a UV lamp (220) inserted into the insertion hole (211) of the fixed body (210) to radiate light by receiving power from a battery or external power source, and a twisted moving blade (230) formed outside the UV lamp (220) and having a surface coated with TiO_2 to be rotated in accordance with the rotation of the UV lamp (220). Therefore, the present invention is capable of purifying air by creating a photocatalytic reaction on pollutants contained in the air such as fine dust, bacteria and the like through the purification part and the UV lamp, while more efficiently sterilizing the air with a longer sterilization reaction period as well as a wider area, thereby forming a pleasant indoor environment with higher purification efficiency.
