Description

Technical Field

[0001] The utility model relates to a plasma cleaning machine nozzle, in particular to a cooling type plasma cleaning machine nozzle. Background Art

[0002] In order to obtain good material surface adhesion before surface treatment of workpieces, it is a common treatment method to use plasma for surface cleaning. Plasma is an ionized gaseous substance composed of positive and negative ions generated by the ionization of atomic groups after some electrons are deprived. Plasma is a good conductor and is mainly sprayed onto the surface of the workpiece by the nozzle of the plasma treatment device to achieve the treatment purpose.
