<p>An air purifier, which is mainly comprised of shell body, high-voltage electric sources, ionizing device, at least an electricity-conducting plate, and at least a set of metal filtering net set, wherein, the ionizing device and the metal filtering net set are connected to the high-voltage electric sources of same polarity. And, the electricity-conducting plates are spaced apart by the manner of appropriate distance and are arranged in parallel to the side surface of the metal filtering net set. By arranging the ionizing device at the position of air inlet, the air and micro-dusts sucked into the purifier are charged with charges. And, in the interior, by arranging a metal filtering net set comprised of at least one piece of charged metal filtering net, the charged micro-dusts in the air flowing through the metal filtering net set are expelled by the same polarity charges on the metal filtering net set and pushed toward the electricity-conducting plate located at the position adjacent to the air inlet. And, the charged micro-dusts are attracted by the different polarity charges and adsorbed onto the electricity-conducting plate to reach the function of purifying air.</p> |
