Abstract: A voltage application device includes a voltage application circuit. The voltage application circuit applies application voltage between discharge electrode and counter electrode which face each other with a clearance left from each other to generate a discharge. The voltage application device forms discharge path partially and dielectrically broken between discharge electrode and counter electrode when a discharge is generated. Discharge path includes first dielectric breakdown region formed around discharge electrode, and second dielectric breakdown region formed around counter electrode.

Abstract: A discharge device according to the present disclosure includes a discharge electrode and a voltage applicator that applies a voltage to the discharge electrode and thus causes discharge that is further developed from corona discharge at the discharge electrode. The discharge is discharge in which a discharge path is intermittently formed by dielectric breakdown so as to stretch from the discharge electrode to a surrounding. This discharge can be called leader discharge. This makes it possible to increase an amount of generated active component while keeping an increase of ozone small.

CPC classification number: H01T19/00
Abstract: An electric discharge device according to the present disclosure includes a discharge electrode, a counter electrode, a voltage application circuit, and a liquid supply unit. The discharge electrode is a columnar electrode. The counter electrode faces the discharge electrode. The voltage application circuit applies an application voltage between the discharge electrode and the counter electrode. The liquid supply unit supplies liquid to the discharge electrode. The liquid extends and contracts along a central axis of the discharge electrode by discharge. The counter electrode includes a peripheral electrode part and a projecting electrode part. In a direction along the central axis of the discharge electrode, a tip of the liquid in a state in which the liquid extends is located at the same position as an outer peripheral edge of the peripheral electrode part or located closer to the discharge electrode than the outer peripheral edge.

Abstract: An electrostatic atomizing device of the present disclosure includes a discharge electrode, a counter electrode, a liquid supplying unit, a current path, a voltage applicator, and a limiting resistor. The limiting resistor is disposed on a first current path or a second current path included in the current path. The first current path electrically connects the voltage applicator and the counter electrode, and the second current path electrically connects the voltage applicator and the discharge electrode. This makes it possible to increase an amount of generated radicals while keeping an increase of ozone small. In addition, an electric current peak of an instantaneous electric current can be kept small.
