Abstract
The invention relates to a portable micro hollow cathode discharge plasma jet device, comprising a micro hollow cathode discharge electrode, an excitation source module, a gas supply module and an insulating housing, wherein the insulating housing wraps the micro hollow cathode discharge electrode, the excitation source module and the gas supply module in the interior, and a nozzle is arranged atthe front end of the insulating housing. The excitation source module comprises a charging lithium battery, a low-voltage DC voltage stabilizing circuit, a DC voltage boosting circuit, a high-voltagepulse generator and an impedance matching circuit electrically connected in turn, wherein the impedance matching circuit is connected with a micro hollow cathode discharge electrode, the air supply module is connected with the micro hollow cathode discharge electrode and is directly supplied with power by the low-voltage DC voltage stabilizing circuit. As the portable micro-hollow cathode discharge plasma jet device uses air as a gas source, the portable micro-hollow cathode discharge plasma jet device can get rid of the gas supply problem of rare gas, solve the problem of converting glow discharge to arc discharge at high pressure, and generate air glow plasma.
Description
technical field [0001] The invention relates to a portable micro-hollow cathode discharge plasma jet device. Background technique [0002] Atmospheric pressure-cooled plasma jet transports the active free radicals, charged particles, highly active molecules and atoms generated in the discharge area to the treated area through gas flow, breaking through the space limitation of traditional cold plasma, and being used in biomedicine, material modification, energy Chemical industry and other fields have broad application prospects. The generation of atmospheric cold plasma requires not only external excitation sources (such as 220V power frequency AC, signal triggers, high-voltage cables and other ancillary equipment) but also working gas supply (such as gas cylinders, mass flow meters, pressure reducing valves, etc.). These complex and necessary auxiliary equipment limit the application of outdoor occasions or emergency situations. [0003] In recent years, the appearance of ...
