[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0030] The terms used herein are only for describing specific embodiments and are not intended to be limiting of the present invention. Singular forms such as "a", "this", "here", "this" and "the" as used herein also include plural forms.

[0031] See attached Figures 1 to 5 As shown, a spray gun handle of this embodiment includes a handle body 1, which has a central longitudinal axis and an outer contour configured with a user's hand-held grip, and is held by one hand for operating the spray gun.

[0032] The handle body 1 is arranged or formed on the spray gun and includes a handle right cover 11 and a handle left cover 12. The handle right cover 11 and the handle left cover 12 are aligned and buckled along the central longitudinal axis to form a receiving cavity, and the electric wire 5 and the water pipe 6 are arranged in the receiving cavity. Since the handle body 1 has a stable spatial structure inside, the distance between the electric wire 5 and the water pipe 6 is increased to avoid contact between the water and electricity, thereby providing safety performance.

[0033] The handle body 1 is provided with an electric wire 5 and a water pipe 6 which passes through the front and rear ends of the handle body 1, and the electric wire 5 and the water pipe 6 are spaced apart and insulated. The electric wire 5 and the water pipe 6 can be reliably insulated by ensuring a sufficient spacing distance. The electric wire 5 and the water pipe 6 can be reliably insulated by providing an insulating structure such as a rubber pad (not shown in the figure).

[0034] A key switch 3 is provided on the handle body 1, and the key switch 3 acts on a key PCB board 4 in the handle body 1. The key PCB board 4 is electrically connected to the first end of the wire 5, and the second end of the wire 5 is electrically connected to the working circuit of a water pump. The water pump is arranged in a barrel body. When the key switch 3 is pressed, the water pump can be controlled to start or stop working.

[0035] The first end of the water pipe 6 is connected to a spray bar 8, and the second end of the water pipe 6 is connected to the barrel body.

[0036] Among them, the wire 5 and the water pipe 6 both extend out through the through hole 2 opened at the rear end of the handle body 1, and the first end of the wire 5 is electrically connected to the key switch 3 through a key PCB board 4, and the second end of the wire 5 is electrically connected to the working circuit of the water pump (for example: the host PCB).

[0037] The spray rod 8 of this embodiment is connected to the head of the handle body 1 , the first end of the spray rod 8 is connected to the handle body 1 through a spray rod joint 7 , and the second end of the spray rod 8 is sleeved with a spray head 9 .

[0038] The nozzle 9 of this embodiment can be used to selectively discharge a pressurized fluid, or to jointly discharge a gas-liquid mixture or a solid-liquid mixture consisting of a pressurized fluid and at least one additive; wherein the additive is selected from the following group, which includes: solid particles, fire extinguishing powder, fire extinguishing additives, foaming agents, dry ice, detergents, etc.

[0039] The nozzle 9 is connected to a nozzle 10 for changing the speed and direction of the liquid jet, and the position of a single nozzle can be adjusted, so as to improve the overall working condition adaptability of the water jet loom equipment; the nozzle 10 is provided with a plurality of spray holes, and the spray holes are evenly distributed on the liquid jet surface of the nozzle 10 with the axis of the nozzle 10 as the circle point, and the structural layout relative to the nozzle 10 is reasonable. The shape of the spray hole can be circular, square, triangular, etc., and spray holes of different shapes will produce different jet flow shapes. The size and position of the spray hole will also affect the flow rate and speed of the jet flow, so it is necessary to select different spray hole sizes and shapes according to different application scenarios.

[0040] The working principle of this utility model:

[0041] During operation, pressing the key switch 3 or moving away from the key switch 3 controls the spray gun operation.

[0042] When the key switch is pressed by hand, the key switch 3 triggers the key PCB board 4, and the key PCB board 4 transmits the electrical signal to the working circuit of the water pump through the wire 5. The working circuit of the water pump controls the water pump to start the operation, triggering the liquid storage barrel where the water pump is located to transport liquid to the spray gun along the water pipe 6, pumping water to the spray rod 8, and finally spraying it out from the spray head 9. In this way, the spray gun handle can be effectively operated with one button, and water and electricity can be turned on at the same time, which is convenient for single-handed control.

[0043] When the hand is away from the key switch, the key switch 3 is disconnected, the key switch 3 is separated from the key PCB board 4, and the electrical signal transmitted from the key PCB board 4 to the working circuit of the water pump through the wire 5 is interrupted, thereby turning off the water pump and stopping the liquid storage barrel where the water pump is located from delivering liquid to the spray gun along the water pipe 6, so as to realize the simultaneous cutting off of circuit control and water circuit control.

[0044] The utility model realizes the triggering of the key switch and the simultaneous conduction of the water channel and the electric circuit, thereby improving the convenience and sensitivity of use.

[0045] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
