Plasma cleaning machine convenient to maintain

Abstract

The invention relates to a plasma cleaning machine convenient to maintain. The plasma cleaning machine convenient to maintain comprises a plasma generator, wherein the plasma generator is connected with a spray gun, a cylindrical gun head is arranged on an end portion of the spray gun, an installation hole which matches the gun head is formed in an end portion of the spray gun, the gun head comprises a pipe connected with the installation hole through threads, the end, away from the installation hole, of the pipe protrudes outwards to form a flange, a plurality of strip grooves are formed in the outer circumferential surface of the pipe in a circumferential array mode, the strip grooves are formed in an axis direction of the pipe, one end of each strip groove extends onto the flange, and agas vent which communicates with the interior of the pipe is formed in the bottom surface of each strip groove. In an ionization process, electric arcs which are generated on an electrode can be discharged through the gas vents along with gas flows preferentially, and the electric arcs can be locked in the strip grooves when located in the strip grooves so that by forming the gas vents and the strip grooves, effects of arc striking and arc extinguishing can be achieved, thus the electric arcs generated on the electrode cannot be sprayed out of the gun head, and the safety in a use process canbe effectively improved.

Description

technical field [0001] The invention relates to the technical field of plasma cleaning equipment, in particular to a plasma cleaning machine which is easy to maintain. Background technique [0002] The working principle of the cellular plasma generator is to generate a huge energy release at the moment of neutralizing the positive and negative charges of the positive and negative ions in the air, which will lead to the change of the structure of the bacteria around it or the conversion of energy, resulting in the death of the bacteria. realize its bactericidal effect. Since the number of negative ions is greater than that of positive ions, the excess negative ions are still floating in the air, which can eliminate smoke, dust, eliminate odors, improve air quality, and promote human health. [0003] When in use, the plasma generator is generally used in conjunction with the nozzle to form a plasma cleaning machine. The plasma generator supplies gas to the nozzle and provides...

AI Technical Summary

Problems solved by technology

[0004] Due to the high voltage required to ionize the gas, an arc is easily generated on the electrode during the ionization process, and the arc will be discharged along with the gas during the gas flow process, so that during the disinfection process of the object, the spray from the gun head The arc out is not only easy to damage objects, but also has certain safety hazards.
