Further, the diameter of the water jet is 0.5mm-2mm, for example, the diameter of the water jet can be 0.5mm, 0.75mm, 1mm, 1.5mm or 2mm, and can be selected according to the actual situation, and by limiting the diameter of the water jet within the above range, the liquid can be smoothly sprayed from the water jet, and the fineness of the water liquid sprayed from the water jet can be ensured.

Specifically, the purification assembly 20 is driven by the motor to rotate at a high speed, water at the bottom of the rotating cavity 10a flows upwards along the water inlet pipe 60 under the driving action of the water pump 300 and is sprayed out through the water spray nozzles on the water inlet pipe 60, water is sprayed into the purification assembly 20, and the purification assembly 60 rotating at a high speed captures droplets entrained by the air flow and is thrown onto the inner wall of the rotating cavity 10a under the action of centrifugal force while purifying the air flow.

According to the air purifier disclosed by the embodiment of the invention, the diversion device 30 is arranged at the part below the purification component 20 on the inner wall of the rotary cavity 10a, wherein the purification component 20 can purify air and capture small liquid drops in air flow, the purification component 20 can throw the intercepted liquid drops to the inner wall of the rotary cavity 10a, and in the process that water liquid is gathered on the inner wall of the rotary cavity 10a and flows downwards along the inner wall, the water liquid can be received on the diversion device 30, so that the water liquid is prevented from contacting with the air inlet 11, meanwhile, the diversion device 30 can also divert the water liquid to the position of the water storage cavity 10b, the cyclic utilization of water resources is ensured, and the performance of the air purifier is improved.
