[0002] In the prior art, high-pressure cleaning machines are widely used. For example, people usually use high-pressure cleaning machines to clean household vehicles. Since high-pressure cleaning machines use high-pressure water pumps to generate high-pressure water, they have remarkable effects on cleaning the body and wheels full of sludge, and are both clean and fast to clean. They can also clean moss and dirt that are difficult to clean and have adhered to stone steps or walls for many years, making the walls look brand new, and can meet the cleaning needs of daily life, which is very convenient.

[0003] A high-pressure cleaning machine generally includes a frame, a push rod fixedly arranged at the lower end on the frame, wheels rotatably arranged on the frame, a high-pressure water pump installed on the frame, and a motor installed on the frame and drivingly connected to the high-pressure water pump. The high-pressure water pump usually has a water inlet and a water outlet. Its water inlet can be connected to an external water source to draw water from the external water source. For example, tap water, etc. Its water outlet is usually connected to a high-pressure water gun, and various accessories such as nozzles can usually be installed on the high-pressure water gun. Among them, the high-pressure water gun includes a gunstock. There is a trigger switch between the gunstock and the gun barrel that can only be used to control the on-off of water flow. There is a nozzle at the mouth of the gun barrel. This kind of high-pressure water gun has a simple structure and cannot display real-time pressure and adjust the water outlet pressure of the high-pressure water gun during specific use, so it is not very convenient to use; for this reason, a high-pressure cleaning water gun and a high-pressure cleaning machine capable of monitoring and displaying real-time pressure are proposed.

Two pressure gauges 173 are respectively installed at the front and rear ends of the installation part 174, and are respectively used for displaying the water pressure before and after the water pressure of the barrel 12 is adjusted.

[0033] By adopting the above structural design, a pressure regulating display 17 for adjusting the water pressure and displaying the water pressure in real time is provided on the barrel 12 of the high-pressure cleaning water gun, so as to overcome the problems that the existing high-pressure water gun has a simple structure, cannot display the real-time pressure and cannot adjust the water outlet pressure of the high-pressure water gun during specific use, and is not convenient to use. Specifically, the pressure regulating display 17 includes a connecting pipe 171. An installation part 174 is provided in the middle of the connecting pipe 171. A water pressure regulating component is installed on the installation part 174, and two pressure gauges 173 are respectively installed at the front and rear ends of the installation part 174, and are respectively used for displaying the water pressure before and after the water pressure of the barrel 12 is adjusted, making the measurement data diversified.

[0034] In this embodiment, the installation part 174 includes an annular seat 1741 arranged along the circumferential direction of the barrel 12 and a rod sleeve 1742 arranged along the radial direction of the barrel 12. The rod sleeve 1742 is communicated with the annular seat 1741.

In the initial state, the water flow channel 1771 of the spherical valve 177 is aligned and communicated with the water flow channel 1771 of the hemispherical cover 719, and the water flow is completely unobstructed. When the spherical valve 177 rotates a certain angle, the water flow channel 1771 of the spherical valve 177 and the water flow channel 1771 of the hemispherical cover 719 are not completely aligned, and the water flow pressure at the nozzle 16 end decreases.
