Patent ID: 8418942

Claim:
An oxidation and reduction fine particles generator, comprising: an atomization electrode; a water feeder configured to supply water to the atomization electrode; a high voltage generator configured to apply a high voltage to the atomization electrode; and a controller configured to control the water feeder and the high voltage generator, wherein the oxidation and reduction fine particles generator further comprises a switch device configured to change an operation mode to an oxidation mode or a reduction mode, wherein the controller is configured: to generate negatively charged minute water particles including radicals through electrostatic atomization by activating each of the water feeder and the high voltage generator to apply a high voltage to the water supplied to the atomization electrode, when the operation mode is changed to the oxidation mode, and also to inactivate and activate the water feeder and the high voltage generator, respectively, to generate reduction fine particles from the surface of the atomization electrode by dry discharge, when the operation mode is changed to the reduction mode.
