Rotary spray head device for high-pressure cleaning machine

Abstract

A rotary spray head device for a high-pressure cleaning machine relates to an accessory for the high-pressure cleaning machine. The rotary spray head device for the high-pressure cleaning machine comprises a spray head cover body connected with a water gun, wherein a water inlet base is arranged at the upper end of the inner cavity of the cover body; a water outlet base is arranged at the bottom end of the inner cavity of the cover body; radial through holes are formed at the bottom of the cover body below the water outlet base; a rotator is arranged inside a cavity between the water inlet base and the water outlet base; the water inlet base consists of a drain plug and a water inlet cabin; a sealing ring is arranged at the junction of the drain plug and the inner wall of the cover body; the water inlet cabin takes the shape of a lug boss; a step-like groove is formed in the center of the water inlet cabin; water inlets are formed at the bottom of the groove and deviate from the center of the water inlet cabin; the bottom of the rotator is arc-shaped; an end socket is arranged at the top end of the rotator; a central hole communicated with the water inlet is formed in the inner wall of the rotator; a sealing ring is arranged on the outer wall of the rotator; the water outlet base is a step-like lug boss; a radial water outlet is formed in the center of the water outlet base; a bowl-shaped arc groove is formed in the top surface of the water outlet base; the water outlet is communicated with the arc groove; and the bottom of the rotator contacts the arc groove.

Description

technical field [0001] The invention relates to an accessory for a high-pressure cleaning machine, in particular to a rotary joint. Background technique [0002] At present, the nozzles of high-pressure cleaners on the market are mostly linear nozzles connected to water guns, and the sprayed water is mostly linear, which cannot effectively clean multiple angles, and the cleaning efficiency is poor, which can be effectively improved. [0003] In order to solve this problem, the existing nozzles on the market have been improved, and the water outlet of the nozzle has been changed into a radial shape, so that the linear spraying area has become wider and the cleaning range has been expanded. The power is weak, and it can't play a cleaning role very well, and needs to be further improved. Contents of the invention [0004] Aiming at the above technical problems, the present invention provides a rotary nozzle device for a high-pressure cleaner with a wide spray range, strong w...
