  • Patent number: 8157508
    Abstract: Blower apparatus has: an air duct having suction and supply openings; a blower fan for creating a flow of air in the duct; and an electrostatic atomizer. The atomizer includes a hollow body exposed to the air in the duct. The body is provided therein with an electrostatic atomization chamber, and has a barrier, an inlet and an outlet. The barrier is put in the duct so that a part of the air flowing in the duct collides with the front of the barrier and thereby pressure-increased air is obtained. The inlet is located at the front side of the barrier so that the pressure-increased air can enter the chamber through the inlet. The outlet is located at the rear side of the barrier so that all the pressure-increased air higher than that of the air flowing in the duct, from the chamber can flow out into the duct.
