Low-temperature plasma generator with hexagon pipe-type structure

The present invention discloses a low-temperature plasma generator with a hexagon pipe-type structure. The low-temperature plasma generator comprises a copper rod, a generator cavity and a metallic mesh. The generator cavity is in the shape of a regular hexagon pipe, is made of quartz glass or corundum and is used as a medium in the middle of a discharging gap. The shape of the copper rod is the same with that of the generator cavity, and the copper rod is arranged in the generator cavity; both ends of the copper rod are sealed and fixed by positioning stoppers, and a through hole used for installing an aeration pipe is formed in each positioning stopper; and the metallic mesh wraps the outer surface of the generator cavity, and is used as a grounded negative electrode so as to ensure normal discharging, and fixes the generator cavity. During operation, the copper rod is connected to a high-voltage power source positive electrode by a positive electrode wiring head, the metallic mesh is connected to a high-vo
