Handheld plasma electric torch

Abstract

The invention relates to a handheld plasma electric torch. The handheld plasma electric torch comprises an electric torch shell, a battery rack, a rechargeable battery, a low voltage switch, a booster, a first resistor, a second resistor, an electrode interface, an electrode, a booster fixing rack and an electrode interface fixing rack, wherein the rechargeable battery is connected with the low voltage switch and the booster; the battery rack is arranged on the lower part of the electric torch shell; the rechargeable battery is arranged in the electric torch shell and fixed by the battery rack; the electric torch shell is a hollow cavity and is provided with a handheld part which is made of a conductive material; an opening for accommodating the electrode is formed at the upper end of the electric torch shell; the booster is fixed in the electric torch shell by the booster fixing rack; the high voltage output end of the booster is connected with the electrode interface by the first resistor; and the low voltage end of the booster is connected with the handheld part of the electric torch shell by the second resistor. By using the handheld plasma electric torch, the problems that a power supply is expensive, the volume is large, the power supply works only when grounded and cannot be moved, the area of generated plasmas is small and the like in the conventional atmosphere pressure plasma device has can be solved.

Description

technical field [0001] The invention belongs to a plasma generating device, in particular to a hand-held plasma torch. Background technique [0002] Atmospheric pressure non-equilibrium plasma is a plasma generated under atmospheric pressure. The temperature of electrons can be as high as tens of thousands of degrees, while the temperature of ions and neutral particles is much lower than the temperature of electrons, which is close to or equivalent to room temperature, so the temperature of the discharge gas is also close to room temperature. . Non-thermal equilibrium plasma can be widely used as a highly active reactant in various fields, such as plasma deposition and coating, etching, surface treatment, chemical purification, biological purification and medical applications. [0003] In the prior art, methods for generating plasma under atmospheric pressure mainly include: dielectric barrier discharge (DBD) plasma, plasma jet, micropore discharge, and the like. [0004] ...
