As further improvement of the utility model, between the described body of a gun and described power stream mouth, be connected with a sealing gasket or O type circle by nozzle carrier.
As further improvement of the utility model, on the outer wall of described the first body, be also connected with sheath, within described power stream mouth and cavitation jet pipe are all positioned at described sheath.
As further improvement of the utility model, described pore is three to six and is evenly distributed on the tube wall of described the first body.
The beneficial effects of the utility model are, pull the trigger on pikestaff, highly pressurised liquid in the body of a gun ejects from rifle, form power stream, power stream is taken away gas wherein during through the first body of cavitation jet pipe, and make to form vacuum zone in the first space of cavitation jet pipe, by the pore air amount on cavitation jet pipe.High speed power stream carry and the air that compresses suction from cavitation jet pipe spraying to the scope of operation, after ejection because pressure declines suddenly, the bubble moment explosion forming, thus increase fragmentation to scope of operation schmutzband, peel off, infiltration, erosion effect, improve cleaning efficiency.
