The present invention relates to a high pressure cleaning device having suds cleaning efficacy comprising a control body, containing a Venturi tube seat at the interior thereof, connected to the output of a pump, one side of the body being an inlet for the feeding of detergent and the other side being connected to a high pressurized air output pipe such that the water stream a nd the detergent are mixed and formed into suds flowing out from an water outle t of the body to the outside for cleaning purpose, characterized in that a bending opening is provided to the middle section of the of the body connected to th e inlet and outlet water passage, and the opening edge of the bending opening, corresponding to the lateral side of the body, a pressure-adjusting device i s provided and a plug shaft is inserted at the bending opening and in combination with the conic shape end of the shaft body and a press board mounted at the bottom end of the plug shaft to resist the pressure change of the pressure within the interior of the body, such that the press board is slidably moved within the air chamber of the body, the board moved to one lateral sid e will simultaneously pull the plug shaft to close the opening edge of the bending opening, thereby the water inlet or outlet is automatically closed a t an appropriatetime so as to ensure the stability of pressure within the body</S DOAB> |
