Abstract

An air-purification electric fan with dual-layer blades, comprising a shell, a fan set, a fan motor, a fan shroud (4), and a plasma high-voltage generator. The fan set consists of an active fan and a passive fan. When the active fan is turned on and starts rotating, air passes through the active fan shroud (4) and then through a plasma generation pole with high-voltage negative charges; the plasma generation pole discharges to the air to ionize the air, so that the air is filled with anions and is sucked to the plasma collector electrode active fan with high-voltage positive charges, so as to be preliminarily purified; then the air enters the passive fan, wherein due to negative charges generated by induction on the surface of the passive fan adjacent to the active fan, different pollutants with positive charges are further adsorbed, and due to positive charges generated by induction on the surface of the passive fan opposite to the active fan, different pollutants with negative charges are further adsorbed, so that second air purification is implemented; and the purified air is discharged by means of the shroud. The plasma is fully used by means of multiple forced reactions, and thus there are few residual free radicals of ozone at an air outlet of the purifier, so that the air-purification electric fan can not only efficiently remove solid and gaseous pollutants in air, but also accelerate air circulation, thereby achieving high security and a high price-performance ratio.

Description

Technical field

In particular, organic pollution, bacterial contamination and PM2.5 pollution have seriously impeded the improvement of people's quality of life. The existing electric fan only has a blowing function. Therefore, it is only used in the days of enthusiasm, and the utilization rate is not high, but it takes up space. The air purifier generally has the functions of removing smoke, removing odor, removing bacteria and negative ions, but has no blowing function. In polluted air, negative ions adsorb or agglomerate dust and bacteria and become heavy ions, which are harmful to the human body. Moreover, the air circulation efficiency is low, so that the ozone concentration gradient is large and the utilization is insufficient. And the negative ion generator, or plasma generator, has a single use and takes up space.
