Air purifying machine and fan thereof

Abstract

The invention discloses an air purifying machine and a fan thereof, and provides a fan. The fan comprises a housing, an impeller mounted in the housing, a motor driving the impeller to rotate and an air guiding device which surrounds the periphery of the impeller and is located in the housing, wherein the impeller comprises a plurality of blades which are all distributed on a first circle and rotate and incline in a first clock direction; the air guiding device comprises a plurality of air guiding pieces which are all distributed on a second circle and rotate and incline in a second clock direction; the second circle is located outside the first circle and concentric with the first circle; and a plurality of air outlets are formed between adjacent air guiding pieces, and a plurality of exhaust outlets are formed in the periphery, corresponding to the air outlets, of the housing. The invention further provides the air purifying machine, and the housing is mounted at the top of a casing. By means of the fan, a volute with a larger size is removed, the air guiding pieces with smaller sizes are adopted, the plurality of air outlets are formed between adjacent air guiding pieces, so that air flows are equally distributed through the plurality of air outlets, then pass the air outlets and are uniformly discharged through the exhaust outlets in the housing, the air pressure is reduced, the air speed becomes more appropriate and meets requirements of a human body, and air outlet amount is increased.

Description
