Handheld portable generating device for sliding arc low-temperature plasma

Abstract

The invention discloses a handheld portable generating device for sliding arc low-temperature plasma. According to the structure, a miniature air pump is connected with an insulating sleeve through a silica gel conduit, the insulating sleeve is located between a high-voltage electrode and a ground electrode, a high-voltage power source supplies power to the high-voltage electrode and the ground electrode, the high-voltage power source, the high-voltage electrode and the ground electrode are embedded in a handle, a hole is formed in the front end of the handle, so that the plasma is sprayed out, and a control switch is arranged on the handle so as to control the high-voltage power source to work. The generating device has the advantages that the length and the temperature of the plasma are changed through adjustment of the voltage, operation is simple and flexible, and the device can be used conveniently by an operator; the device is small in size, convenient to carry, attractive in appearance and low in cost; air or simple substance gas or a mixture of air and simple substance gas or a gaseous compound or gaseous organic matter serves as the working gas and various requirements can be met; other excitation devices are not needed, faults are reduced, and reliability of the device is improved; the generating device is different from a traditional plasma source, a sliding arc is more efficient, the activity of generated plasma particles is better, and the particles are more beneficial to the human body and the material treatment effect.

Description

Technical field [0001] The invention is a handheld portable sliding arc low-temperature plasma generator, which belongs to the technical field of plasma. Background technique [0002] Existing portable low-temperature plasma generators generally use rare gases or mixed gases containing oxygen, and additional devices are added in addition to high-voltage electrodes. For example, a portable low-temperature plasma generator (ZL201120032919.0) of the existing patent uses the ultraviolet light generated by the ultraviolet light source and the alternating electric field of the high-voltage electrode to act on the gas to generate low-temperature plasma. However, in addition to the high-voltage electrode, the device needs to add an additional UV light source and a protective layer resistant to ion corrosion. Therefore, the cost will be greatly increased and the possibility of device failure will increase. In addition, the life of the ultraviolet light source will directly affect the lif...

AI Technical Summary

Problems solved by technology

The working gas of the device is limited to oxygen, and the cost is relatively high

In addition, oxygen is a combustion-supporting gas, and improper operation can easily cause danger.

Therefore, the scope of use is limited

The arc temperature generated by the traditional device is high and the current is high, which cannot be touched by the human body

Existing sliding arc devices generally only have one arc ignition point, so the efficiency of plasma generation is low
