Title: PLASMA AIR-PURIFICATION BLADELESS ELECTRIC FAN
Abstract:
A plasma air-purification bladeless electric fan, comprising a fan base, a shell (1), a blower motor, a collector electrode conductive fan (6), a blowing ring (3), an oscillating means, and a plasma high-voltage generator (13). A plasma generation pole (7) is provided within the air inlet of a fan shroud; when the collector electrode conductive fan (6) is turned on and starts rotating, air passes through the fan shroud and then through the plasma generation pole (7) with high-voltage negative charges, so that the air is ionized and filled with anions; the air passes through the collector electrode conductive fan (6) with high-voltage positive charges, so as to be preliminarily purified; then, the air flows upwards to the inner cavity of the blowing ring (3), and the air with anions induces the inner cavity wall of the blowing ring (3) to form a surface having a film with positive charges, thereby implementing second air purification. The plasma is fully used by means of multiple forced reactions, and thus there are few residual free radicals of ozone that would cause damage to a human body; therefore, the bladeless fan is safe. Moreover, high air circulation rate and dust removal efficiency are implemented, and the air purification effect is improved.
