Connection, the interior intracavity of the described body of a gun is additionally provided with high pressure liquid stream, described pikestaff is additionally provided with for controlling this highly pressurised liquid to enter institute
State the trigger of injection apparatus it is characterised in that described injection apparatus include nozzle carrier, the power stream nozzle of tapered tubular and ladder pipe
The cavitation jet pipe of shape, described power stream nozzle big opening end is connected on described nozzle carrier, and described cavitation jet pipe includes big of bore
One body and bore little the second body, described first inboard wall of tube body is provided with a boss, described its outside wall portions of power stream nozzle
Divide and be stuck on described boss, form one end and close, the first space that the other end is connected with described second tube cavity, described first
The pore that some and described first space connects is additionally provided with the tube wall of body.
As a further improvement on the present invention, pass through between the described body of a gun and described power stream nozzle nozzle carrier and a sealing gasket or
O-ring connects.
As a further improvement on the present invention, the outer wall of described first body is also associated with sheath, described power stream nozzle
It is respectively positioned within described sheath with cavitation jet pipe.
As a further improvement on the present invention, described pore is three to six and is evenly distributed on the pipe of described first body
On wall.
The beneficial effects of the present invention is, pull the trigger on pikestaff, the highly pressurised liquid in the body of a gun ejects from rifle,
Form power stream, power stream takes away gas therein when the first body of cavitation jet pipe, and make the of cavitation jet pipe
Form vacuum zone in one space, air is sucked by the pore on cavitation jet pipe.High speed power stream carries and compresses the sky of suction
Gas from cavitation jet pipe spraying to the scope of operation, because pressure declines suddenly after ejection, the bubble moment explosion of formation, thus increase right
Scope of operation schmutzband broken, peel off, infiltration, erosion effect, improve cleaning efficiency.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further details.
As Figure 1-4, the present invention includes pikestaff 2, is connected to the body of a gun 4 on described pikestaff 2, and with the described body of a gun 4
The inner space of the injection apparatus 8 connecting, the inner chamber of the described body of a gun 4 and described injection apparatus 8, the interior intracavity of the described body of a gun 4 is also
It is provided with high pressure liquid stream, described pikestaff 2 is additionally provided with for controlling this highly pressurised liquid to enter the trigger 10 of described injection apparatus 8, institute
State the cavitation jet pipe 14 that injection apparatus 8 include nozzle carrier 28, the power stream nozzle 12 of tapered tubular and ladder tubulose, described power stream
Nozzle 12 big opening end is connected on the described body of a gun 4, described cavitation jet pipe 14 include the first big body 16 of bore and bore little
Second body 18, described first body 16 inwall is provided with a boss, and described its outer wall section of power stream nozzle 12 is stuck in described convex
