Embodiment 1

[0075] exist figure 1 , figure 2 In the illustrated embodiment, a spray gun comprising:

[0076] The gun body 2, the interior of the gun body is provided with a spray liquid channel 8 and a liquid pressure channel 22 which communicate with each other;

[0077] The nozzle part 20 is rotatably connected to the gun body 2 to open or close the liquid spray channel 8 and realize the spray or foam spray function;

[0078] The pressure chamber part 21 is arranged on the gun body 2 and is arranged parallel to the liquid spray channel 8 below the liquid spray channel 8 to realize the air compression position; the pressure chamber part 21 includes a piston cylinder 210, a pressure chamber 211 and Piston 212, the piston 212 is slidingly sealed inside the pressure chamber 211 and realizes the suction action of the spray gun through the change of air pressure inside the pressure chamber 211; wherein, the piston 212 is located along the axis from the outside of the piston to the middle p...

Abstract

The invention discloses a spray gun. The spray gun comprises a gun body, a nozzle part, a pressure cavity part and a liquid communicating part, wherein a liquid spraying channel and a liquid pressingchannel which communicate with each other are arranged in the gun body; the pressure cavity part comprises a piston cylinder body, a pressure cavity and a piston, the piston is arranged in the pressure cavity in a sliding and sealing mode, and the suction action of the spray gun is realized through the air pressure change in the pressure cavity; an air hole is formed in the piston from the outsideof the piston to the middle position in the axis direction; an opening and closing device is arranged in the liquid communicating part; a reverse spraying device for realizing the functions of forward spraying, reverse spraying and 360-degree inclined side spraying of the spray gun is inserted into one side, facing a liquid container, of the opening and closing device in a sealing mode; and an air passing and liquid passing opening communicating with the liquid pressing channel and the opening and closing device is formed in the side wall of one side, facing the liquid communicating part, ofthe cavity bottom of the pressure cavity. According to the spray gun, the functions of forward spraying, reverse spraying, 360-degree inclined side spraying and spraying or foam spraying and line spraying can be realized, meanwhile, the operation of children can be effectively avoided, and liquid overflow in the transportation process is prevented.

Description

technical field [0001] The invention relates to the technical field of liquid pressure pumps, in particular to a spray gun that can be connected to a liquid pressure pump, especially a spray gun with the functions of forward spraying, backward spraying and 360-degree oblique side spraying. Background technique [0002] Liquid pressure pumps are widely used in daily life, such as bottled liquid products such as kitchen oil cleaning solution, shampoo, cosmetics, perfume, insect repellent, etc., all of which use liquid pressure pump technology. Compared with the traditional bottle opening method, it is more convenient and efficient, and the output is very large. [0003] The spray gun is an indispensable tool for use with common liquid pressure pumps. It usually includes structures such as a gun body, a piston rod and a trigger, and is used in conjunction with a liquid container. Its main working principle is to use the internal pressure of the piston to increase the internal ...
