Problems solved by technology
[0004] 1. The user needs to press the handle of the spray gun continuously when using it, which is laborious and not suitable for long-term use;
[0005] 2. When using the spray gun, with the change of the water inlet pressure, the strength of pressing the handle of the spray gun will also change accordingly, especially in the state of high water pressure, it is more laborious to press the handle of the spray gun, and the operation feel is not good;
[0006] 3. Since the sealing ring is used for sealing, it is easy to leak due to missing installation, improper installation of the sealing ring or aging of the sealing ring during production and use, and the quality is unstable
[0007] 4. The product is not resistant to high water pressure

Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] The present invention provides a spray gun control switch in order to solve the shortcomings of the current spray guns, such as the greater influence of the water pressure on the hand and the laborious operation, such as figure 2 , image 3 As shown, it includes a water inlet connector 12, a valve seat 10, a switch spool 11, and a push steering assembly. The control switch of the present invention can convert the linear operation into the rotation of the switch valve core 11, and then close the waterway. The rotation of the switch spool 11 does not directly oppose the direction of the water flow. Therefore, the change of the water pressure has no influence on the operation of pushing the steering assembly, and the operating feel remains stable, easy and labor-saving.
[0030] When in use, the linear operation pushes the steering asse...

The invention relates to a spray gun control switch which comprises a water inlet connector, a valve seat, a switch valve core and a pushing steering component, wherein the water inlet connector, the switch valve core and the valve seat are connected in sequence; the pushing steering component is connected with the switch valve core; the pushing steering component is subjected to linear operation to drive the switch valve core to rotate; when the pushing steering component is in a closed gear, a waterway from the water inlet connector to the valve seat is blocked; when the pushing steering component is in an open gear, the waterway from the water inlet connector to the valve seat is unblocked; and when the pushing steering component pushes from the closed gear to the open gear, the flow of the waterway from the water inlet connector to the valve seat ison the increase. A spray gun capable of adjusting water discharge volume adjusts water discharge volume through the control switch. According to the spray gun control switch, the pushing steering component converts pushing force to rotating force to achieve the connection of the waterway, the pushing steering component performs rotation control on the switch valve core, the switch valve core rotates to change the switch state, and the water pressure has no influence on the hand feeling of switch control.
Description
technical field [0001] The invention relates to the field of spray guns, in particular to a spray gun control switch and a spray gun capable of adjusting the size of the water output. Background technique [0002] Most of the spray guns of the prior art are used as figure 1 The structure shown is characterized in that the central plug or valve stem is covered with a sealing ring, and the sealing ring is pressed against the water outlet by a spring or water pressure, thereby realizing the sealing of the spray gun when the water is turned off. When using it, press the handle to compress it. The spring separates the central plug or valve stem from the water outlet to realize the purpose of spraying water from the spray gun. [0003] This structure has the following disadvantages: [0004] 1. The user needs to keep pressing the handle of the spray gun when using it, which is laborious and not suitable for long-term use; [0005] 2. When using the spray gun, with the change of...
