Problems solved by technology

The operating part directly drives the blocking part to move or deform. During the process of moving or deforming, the blocking part is subjected to large water pressure area and high water pressure, so the switching force is large, and it is easy to make switching difficult or cause the operating part to break under high pressure.

Embodiment Construction

[0033] Please check figure 1 To 7, it shows the schematic structure of the spray gun, including the fixed part 10, the blocking part 20, the bypass waterway 30, the valve seat 40 and the operating part 50.

[0034] This fixed part 10 is provided with a main waterway 11 . In a specific structure, the fixing part 10 includes a main body 12 , a water diversion body 13 , a water diversion seat 14 , a fixing seat 15 and a cover 16 . The outer peripheral edge of the cover 16 extends along the direction vertical to the cover 16 to form a first peripheral wall, and the first peripheral wall is sealed and fixed in the end port of the body 12 , such as threaded. The water diversion body 13 leans against the surface cover 16 and is located in the first peripheral wall, the fixing seat 15 is located in the first peripheral wall and the top supports the body 12, and the water diversion body 13 is fixed with a second Peripheral wall 136, the outer peripheral edge of the fixing seat 15 ext...

Abstract

The invention discloses a spray gun. The spray gun is characterized in that a fixing part is provided with a main water path, a blocking part is arranged in the fixing part, the connection or disconnection of the main water path can be controlled by the movement or deformation of the blocking part, a water bypass path comprises a penetrating passage, a pressure relief passage and a water pressure change cavity, the penetrating passage penetrates through the blocking part, the water pressure relief cavity is connected between the penetrating passage and the pressure relief passage, a valve seat and an operation part are movably connected with the fixing part, the operation part is rotationally connected with the valve seat to drive the valve seat to move through the movement of the operation part, the valve seat is matched with the pressure relief passage to control the connection and disconnection of the pressure relief passage through the movement of the valve seat, the water pressure change of the water pressure change cavity is controlled through the connection and disconnection of the pressure relief passage, the direction of the resultant force on the blocking part is changed through the water pressure change of the water pressure change cavity, and the blocking part is pushed to move or is controlled to deform, so as to realize the connection and disconnection of the main water path. The spray gun has the beneficial effects that the constant-force switching is realized; the switching force is light; the service life is long; the travel is short.

Description

technical field [0001] The invention relates to a spray gun. Background technique [0002] A traditional spray gun includes a fixed part, a blocking part and an operating part. The fixed part is provided with a main waterway. It is movably connected to the fixed part, and the operating part is connected to the blocking part by transmission so as to directly drive the blocking part to move or deform through the operating part, so as to control the opening and closing of the main waterway. The operating part directly drives the blocking part to move or deform. During the process of moving or deforming, the blocking part is subjected to large water pressure area and high water pressure, so the switching force is large, and it is easy to be difficult to switch or cause the operating part to break under high pressure. Contents of the invention [0003] The object of the present invention is to provide a spray gun to solve the above-mentioned problems in the prior art. [0004...
