Due to the outlet inclination angle of 45°, a rotating jet is formed at the arc surface of the hollow clamping plate to clean the arc surface.

[0028] 3. If the inner sides of the two hollow clamping plates do not meet the cleaning requirements, the liquid pump works to deliver the cleaning liquid into the liquid delivery pipe.
