A device for generating a plasma jet

Abstract

The utility model provides a kind of device generating plasma jet, including power module, control module, gas circuit module and electrode module;The utility model is along glass tube axial interval arrangement by single, double discharge copper ring, and the coaxial discharge structure is formed with needle electrode to be compatible with helium, argon and extend jet, effectively promote jet length and scene adaptability, and transformer is arranged in the position close to electrode module to shorten high-voltage electric energy transmission path, can effectively solve the high-voltage insulation and electromagnetic radiation of wire and handle tail part, integrate PCB board, transformer and other core components in handle shell, and the detachable connecting structure such as the cooperation of clamping protrusion and clamping groove simplifies assembly, reduces the number of components, reduces the device volume, can meet the demand of large material surface treatment, biological medical treatment and other long-distance plasma action scene, overcome the limitation that the jet length of existing device is shorter.
