Dust removal fan for indoor air purification

Abstract

The invention discloses a dust removal fan for indoor air purification. The fan comprises a fan frame, a front cover and a rear cover are arranged at the two ends of the fan frame, four supporting rods are symmetrically and fixedly connected to the inner side wall of the fan frame, and shaft sleeves are fixedly connected to the ends, away from the fan frame, of the four supporting rods correspondingly. According to the fan, by arranging a dust uniform distribution device, a dust filter screen can be automatically driven to rotate under the action of wind power generated by first fan blades, itis ensured that dust, catkin and other impurities intercepted and filtered by the dust filter screen are uniformly distributed, subsequent clearing is facilitated, and the influence on the fan is reduced; a transmission device drives a transmission rod, a transmission shaft and third fan blades to rotate at a high speed, so that negative pressure is formed in an empty groove; and the dust, catkinand other impurities attached to the dust filter screen are sucked into the empty groove by means of a dust suction groove and fed into an impurity storage box under the action of wind force formed by the third fan blades, so that the impurities attached to the dust filter screen are cleared and collected.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a dust removal fan used for indoor air purification. Background technique [0002] Fan often refers to an electric fan, which is a device driven by electricity to generate air flow. The fan inside is energized and then rotates into natural wind to achieve the effect of cooling. [0003] When using a fan indoors, the suction and blowing of the fan can promote the circulation of the nearby air environment, which shows that the fan itself directly participates in the circulation of the indoor air. Therefore, if a dust filter is installed in the fan to intercept the air Dust, catkins and other impurities can make the fan have the effect of air purification, but if there are too many impurities on the dust filter, it will affect the ventilation of the dust filter and affect the normal operation of the fan. Collecting to prevent its re-spreading into the air is again a very t...

[0003] When using a fan indoors, the suction and blowing of the fan can promote the circulation of the nearby air environment, which shows that the fan itself directly participates in the circulation of the indoor air. Therefore, if a dust filter is installed in the fan to intercept the air Dust, catkins and other impurities can make the fan have the effect of air purification, but if there are too many impurities on the dust filter, it will affect the ventilation of the dust filter and affect the normal operation of the fan. Collecting it to prevent it from re-spreading into the air is another very troublesome problem
