First, when the electric fan of the fan blade purifying unit of the present invention is opened, the electric fan is linked to the motor 1 to drive the connector 4 to rotate around the shaft, thereby causing the rotation of the upper and lower plates 10.

When the blade cleaning unit starts to rotate, air inside the blade cleaning unit is discharged outward due to the rotational force of the blade cleaning unit, and therefore, an air pressure difference occurs between the central portion of the blade cleaning unit and the outside of the blade cleaning unit, so that the outside air continuously passes through the central portion of the blade cleaning unit as shown by an arrow D1 in fig. 12, that is, the air inlet flows into the blade cleaning unit.

Further, since the centrifugal force is increased sharply from the central portion of the blade cleaning unit to the outside and the highest wind pressure is formed at the position of the dust collecting filter 20 of the outermost case, the air flowing into the central portion of the blade cleaning unit can smoothly pass through the adsorption part 30 and the dust collecting filter 20, the harmful gas is adsorbed by the adsorption part 30, and the haze is effectively filtered by the dust collecting filter 20 and then discharged to both side directions D2 of the blade cleaning unit.

On the other hand, if the dust collection filter 20 is formed in a shape of repeated unevenness as shown in fig. 2, the dust collection filter 20 functions as an impeller blade, and the fan effect can be further increased.

Referring to fig. 14 and 15, the air blown from the side of the blade purification unit acts as a fan, and if wind reflection plates 90 are additionally provided on both sides of the electric fan shroud as shown in fig. 14, the wind blown from the side of the blade purification unit toward both sides of the electric fan can be turned to blow toward the front direction D3.

In another embodiment, as shown in fig. 15, a plurality of wings 95 are disposed along the circumference of the blade cleaning unit in an inclined structure to change the direction of air flowing into the blade cleaning unit through the air inlet and then discharged to the outside of the dust collecting filter 20, thereby causing air around the blade cleaning unit to flow and improving the fan function. Here, the perimeter of the blade cleaning unit to which the wing plate 95 is attached means the outermost perimeter of the lower plate 10 or the upper plate 60, or a region including the outermost perimeter.
