Plasma sterilization device and electrical equipment

The invention provides a plasma sterilization device and electrical equipment. The device comprises an insulating medium plate; the electrode assembly comprises a first electrode, a second electrode and a grounding electrode, and the first electrode and the grounding electrode are arranged on the first surface and the second surface respectively; the second electrode is arranged on the first surface and is separated from the first electrode, and/or the second electrode is arranged outside the insulating dielectric plate and is opposite to the first electrode on the first surface; wherein the first electrode can discharge to generate charged particles, and the second electrode is used for generating an electric field capable of applying electric field force to the charged particles so as to guide the charged particles to move to extend the coverage area of the plasma. Based on the technical scheme of the invention, the plasma in the discharge area is subjected to extension treatment under the action of the pot
