Portable cold plasma device

Abstract

The invention of a foldable handheld cold plasma device, which includes the following components: The power supply, electronic control circuit connected to the high-frequency transformer, user control panel, and insulated casing enclosing the power supply, electronic control circuit, high-frequency transformer, and user control panel form a unified, hand-shaped unit. The plasma generator contains active and passive electrodes outside the casing, allowing the user to connect to the neutral wire (ground wire) of the device. The device according to the invention utilizes the principle of direct discharge (or discharge through a dielectric barrier with a floating electrode) with a compact size, low cost, and no consumable materials.
