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.

An oxidation and reduction fine particles generator includes an atomization electrode, a water feeder for supplying water to the atomization electrode and a high voltage generator, and also includes a switch device and a controller. The switch device changes an operation mode to an oxidation mode or a reduction mode. The controller generates negatively charged fine water particles including radicals through electrostatic atomization by applying a high voltage to water supplied to the atomization electrode in the oxidation mode. The controller also inactivates and activates the water feeder and the high voltage generator, respectively to generate reduction fine particles from the atomization electrode by dry discharge in the reduction mode.

A platinum microparticles generator comprises a linear first electrode, a board-shaped second electrode, and an applying means. The first electrode contains at least platinum. The second electrode comprises an outlet opening, which is a circular through-hole, located so as to face one end of the first electrode. The applying means applies a voltage between the first and second electrodes. Then, the first electrode has an outside diameter in a range of 0.03 [mm] to 0.10 [mm]. Further, the outlet opening has an inside diameter in a range of 1.0 [mm] to 4.5 [mm]. Thus, the platinum microparticles generator can emit a sufficient amount of platinum microparticles while restraining generation of ozone.

An electrostatic atomizing device for ejecting a mist of charged minute particles includes metal ion elution means for eluting sterilizing metal ions into a liquid to be electrostatically atomized. The metal ions are taken up by the charged minute particles, and are ejected into an environment space together with the charged minute particles, thereby eliciting a sterilizing effect. The elution amount of the metal ions is regulated by varying the voltage applied between two kinds of metal bodies.

Electrostatically atomizing device

The liquid supplied to an emitter electrode located at a tip of an atomization nozzle receives the high-voltage and electrically charged. The mist of the charged minute water particles of nanometer sizes is generated from the emitter electrode. A pressure regulating means regulates a pressure applied to the liquid on the tip of the emitter electrode. Therefore, the mode of generating the mist of the charged minute water particles of nanometer sizes or the mode of generating the mist of the charged minute water particles of nanometer and micron size is selected.

Disclosed is an electrostatic atomizer, which comprises a high-voltage applying section adapted to apply a high voltage between an atomizing electrode and a counter electrode so as to electrostatically atomize water supplied onto the atomizing electrode, wherein the high-voltage applying section is operable to set an absolute value of a voltage to be applied to the atomizing electrode smaller than an absolute value of a voltage to be applied to the counter electrode. This allows a physical object, such as an article stored in a mist-receiving space or an inner wall of a structural member defining the mist-receiving space to become less likely to be electrostatically charged, and makes it possible to avoid causing a problem about discomfort due to discharge of static charges when a user touches the physical object.

The electrostatic atomizer of the present invention can reliably supply water onto the atomizing electrode and electrostatically atomize the water, without restrictions due to temperature/humidity conditions in a mist-receiving space targeted for implementation of electrostatic atomization therewithin, even if the mist-receiving space has a low temperature and/or a low humidity.
