Air purification fan

Abstract

The invention provides an air purification fan in the field of household appliances. Dust in air is removed according to the principle that charges of different properties attract each other, a static electricity generation circuit is arranged in the fan, a cathodic electric field and anodic dust collection nets of left-right plug-in mounting structures are arranged at an air inlet end of the fan, the dust in air is negatively charged when the air passes through the cathodic electric field, and the negatively charged dust is adsorbed on the positively charged anodic dust collection nets when passing through the positively charged anodic dust collection nets so that the purpose of air purification is achieved. Blades of the fan are unbalanced blades, that is, every two adjacent blades are different in size and shape and the blades are arranged at different intervals; flow disturbing ribs are distributed on the blades in an unbalanced way so that noises at multiple different frequencies are generated when the blades rotate; and noise sound waves at different frequencies interfere with one another and attenuate so that the energy of the sound waves is reduced to achieve the purpose of noise reduction. The air purification fan solves the problems that at present a fan cannot purify air and makes a high noise and an air purifier is small in purification capacity and cannot be used as a fan.

Description

technical field [0001] The invention relates to a fan in the field of household electrical appliances, in particular to an air cleaning fan with an air cleaning function. Background technique [0002] At present, the known fans have a large ventilation flow rate but basically do not have the function of air purification. Air purifiers with a small ventilation flow rate are basically not used as fans. Most fans also produce uncomfortable buzzing noises when they are working. Utilization, improve the running noise of the fan, we invented a low-noise air purification fan with air purification function. Contents of the invention [0003] In order to make the fan have the function of air purification, we use the principle of opposite sex attraction to purify and remove the dust particles in the air. In order to achieve the purpose of air purification, we set up a static electricity generating circuit in the fan and set The cathode electric field and the anode dust collection n...
