Air purifier

An air purifier comprises a shell, and a liquid wheel component, a liquid groove for storing liquid, a fan component and a driving motor are arranged in the shell; the liquid wheel component is rotatably arranged in the liquid groove, and partly submerged in a liquid level, and the liquid wheel component is connected with the driving motor through a transmission mechanism; and the air purifier is characterized in that the liquid wheel component comprises a plurality of liquid wheels, and each liquid wheel can be selectively mounted in the liquid groove to form the liquid wheel component, and an annular tooth face is formed on the outer ring of each liquid wheel; the liquid wheels are in transmission connection with a transmission mechanism; the adjacent liquid wheels rotate in the reverse direction under the effect of the transmission mechanism. A combination structure is adopted in the liquid wheel component, and the rotating directions of the adjacent liquid wheels are opposite, so that when the liquid wheels rotate, the liquid wheels can drive a large amount of liquid; regular hexagon liquid storage through holes are distributed in the liquid wheels and are large in ventilation amount, orderly and attractive, and easily form a liquid film; liquid scooping ribs and liquid guide ribs are arranged on the liquid wheels, and the liquid film can be distributed more evenly, and air cleaning can be more facilitated. The air purifier is simple in structure and reasonable in design, the structures of the liquid wheels can be combined, and the air purification and humidification effects can be greatly improved.
