Abstract

A discharge device comprises: a discharge electrode; an electrically insulating portion including an atomization room accommodating the discharge electrode; a water supplier configured to supply water to a surface of the discharge electrode; a high voltage supply configured to apply a high voltage to the discharge electrode to atomize the supplied water as charged water fine particles from a tip portion of the discharge electrode; and an electromagnetic shield provided at least around the atomization room, the electromagnetic shield having an opening to discharge the charged water fine particles.

Claims

1-3. -3. (canceled)

4. A discharge device comprising:

a discharge electrode;

an electrically insulating portion including an atomization room accommodating the discharge electrode;

a water supplier configured to supply water to a surface of the discharge electrode;

a high voltage supply configured to apply a high voltage to the discharge electrode to atomize the supplied water as charged water fine particles from a tip portion of the discharge electrode; and

an electromagnetic shield having an opening to discharge the charged water fine particles, the electromagnetic shield being configured to surround the electrically insulating portion, the water supplier and the high voltage supply,

wherein the electrically insulating portion is provided on an inner surface of the electromagnetic shield.

5. The discharge device according to claim 4, wherein the electromagnetic shield is an electrically conductive case.

6. The discharge device according to claim 4, wherein the electrically insulating portion is an electrically insulating case further accommodating the water supplier and the high voltage supply, and the electromagnetic shield is formed as a conductive layer covering an outer surface of the electrically insulating portion.
