[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] A high pressure cleaning machine, such as Figures 1 to 3 As shown, it includes a frame 1, on which are installed a water tank 2, a filter tank 3, a booster pump 4, a high-pressure plunger pump 5, a driving member 6, a pressure regulating valve 7 and a high-pressure water gun 8. The driving member 6 is used to drive the high-pressure plunger pump 5. In this embodiment, the driving member 6 is preferably a motor, and the output end of the motor is connected to the crankshaft of the high-pressure plunger pump 5.

[0024] The water tank 2 is provided with a water inlet 19 and a drain outlet 20 . External water can be added to the water tank 2 through the water inlet 19 , and water in the water tank 2 can also be discharged through the drain outlet 20 .

[0025] The water tank 2 is connected to the water inlet end of the booster water pump 4. Specifically, in this embodiment, the water tank 2 is connected to the water inlet end of the booster water pump 4 through a pipe body 13, and the water outlet end of the booster water pump 4 is connected to the water inlet end of the filter tank 3. Specifically, in this embodiment, the water outlet end of the booster water pump 4 is connected to the water inlet end of the filter tank 3 through a pipe body 2 14.

[0026] The water outlet end of the filter tank 3 is connected to the water inlet end of the high-pressure plunger pump 5. Specifically, in this embodiment, the water outlet end of the filter tank 3 is connected to the water inlet end of the high-pressure plunger pump 5 through the pipe body 3 15. It should be noted that the filtering effect of the filter tank 3 on water can avoid blockage due to impurities in the water.

[0027] The water outlet end of the high-pressure plunger pump 5 is connected to the pressure regulating valve 7, and the pressure regulating valve 7 is connected to the return water port of the water storage tank 2. Specifically, in this embodiment, the pressure regulating valve 7 is connected to the return water port of the water storage tank 2 through the return water pipe 18.

[0028] The pressure regulating valve 7 is connected to the high-pressure water gun 8 . Specifically, in this embodiment, the pressure regulating valve 7 is connected to the high-pressure water gun 8 through a high-pressure water pipe 17 .

[0029] It should be noted that the pressure regulating valve 7 is used to adjust the pressure of the water flow during the operation of the high-pressure cleaner to avoid unstable operation or even damage due to sudden pressure changes during operation, thereby improving the stability during operation.

[0030] It should be further explained that part of the water flow that exceeds the set water pressure will be collected again from the return pipe 18 and stored in the water tank 2, so as to recycle the water and avoid wasting water resources, so that the water pressure entering the high-pressure water gun 8 is always within the set range of the pressure regulating valve 7.

[0031] The high-pressure plunger pump 5 is provided with a safety valve 9 and a pressure gauge 10. During the operation of the high-pressure cleaning machine, when the pressure is too high, the safety valve 9 starts to open and discharge excess water, thereby further ensuring the stable operation of the high-pressure cleaning machine. The pressure gauge 10 is convenient for users to know the current pressure value.

[0032] The high-pressure water gun 8 is detachably connected to a nozzle 11 , and by replacing the nozzles 11 of different specifications, high-pressure water flows of different angles and pressures can be generated to meet the needs of different scenarios.

[0033] The end of the high-pressure water gun 8 is threadedly connected to the connecting head 12, and the nozzle 11 is threadedly connected to the connecting head 12, and the end of the nozzle 11 extends out of the connecting head 12. It should be noted that the nozzle 11 is replaced as follows. First, when disassembling, the connecting head 12 is rotated by external force to release the threaded connection between the connecting head 12 and the end of the high-pressure water gun 8, and then the threaded connection between the connecting head 12 and the nozzle 11 is released to separate the two; when installing, the nozzle 11 is first threadedly connected to the connecting head 12, and finally the connecting head 12 is threadedly connected to the end of the high-pressure water gun 8. The operation is simple and the nozzle 11 is easy to replace.

[0034] An electric control system box 21 is installed on the frame 1 , and the user can control the operation of the high-pressure cleaner and learn about the operating status through the electric control system box 21 .

[0035] A plurality of casters 22 are provided at the bottom of the frame 1 , and an armrest 23 is provided on the frame 1 . The user can hold the armrest 23 to push the high-pressure cleaner to move. The casters 22 make the high-pressure cleaner more convenient and labor-saving to move.

[0036] The working principle of this utility model is as follows:

[0037] Under the action of the booster water pump 4, the water in the water tank 2 flows to the water inlet end of the booster water pump 4 through the pipe body 1 13, flows out from the water outlet end of the booster water pump 4 and flows to the water inlet end of the filter tank 3 through the pipe body 2 14. The water flows into the filter tank 3 and is filtered. After the filtration is completed, it flows out from the water outlet end of the filter tank 3 through the pipe body 3 15 and flows to the water inlet end of the high-pressure plunger pump 5. After flowing into the high-pressure plunger pump 5, a high-pressure water flow is formed under the action of the high-pressure plunger pump 5, and then flows to the pressure regulating valve 7. Part of the water flows back to the water tank 2 from the pressure regulating valve 7 through the return pipe 18, and the rest of the water flows to the high-pressure water gun 8 through the high-pressure water pipe 17, and is finally sprayed out from the nozzle 11.

[0038] The specific embodiments described in this article are merely examples of the spirit of the present invention; technicians in the technical field of the present invention may make various modifications or additions to the described specific embodiments or replace them in a similar manner, but they will not deviate from the spirit of the present invention or exceed the scope defined by the attached claims.
