[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a low-noise high-pressure cleaning machine, including a main body 1 of the cleaning machine. A support rod 7 is rotatably connected to the top end of the main body 1 of the cleaning machine. A connecting plate 8 is sleeved outside the support rod 7. The front end of the connecting plate 8 is fixedly connected with a fixed rod 9. The fixed rod 9 is used to press against the first spring 11. And the cleaning gun 13 is placed inside the clamp 12. The top end of the pressing block 22 presses against the top end of the clamp 12. And the clamp 12 squeezes the outer first telescopic rod 10 and the outer first spring 11 to deform. The first spring 11 presses against the clamp 12 to clamp it, and there will be no shaking during transportation.

[0024] Specifically, a cleaning module 6 is fixedly connected to the top end of the main body 1 of the cleaning machine. A motor 2 is fixedly connected to the top end of the main body 1 of the cleaning machine. The output end of the motor 2 is rotatably connected with a first threaded rod 3. A sleeve ring 23 is sleeved outside the first threaded rod 3. The first threaded rod 3 pushes the shock box 4 to move to the right to cover the outside of the compression pump 5 and block the noise of the compression pump 5. And the shock pad 14 at the bottom end of the compression pump 5 cushions the compression pump 5.

[0025] Furthermore, the bottom end of the shock-absorbing box 4 is attached to the top end of the cleaning machine body 1 and is slidably connected thereto. The square groove of the shock-absorbing box 4 has a rotating door 18 which is rotatably connected, and can be opened or closed.

[0026] Furthermore, a second telescopic rod 19 is slidably connected inside the circular groove of the shock-absorbing box 4. At this time, the second telescopic rod 19 inside the right side of the shock-absorbing box 4 and the third spring 20 sleeved outside it squeeze the outer rotating door 18. When the rotating door 18 is closed, the rotating door 18 squeezes the second telescopic rod 19 outside it to slide into the circular groove, and the third spring 20 is tightened by the tightening ring 21.

[0027] It should be noted that a shock-absorbing pad 14 is welded to the bottom end of the compression pump 5, and a second threaded rod 16 is fixedly connected to the bottom end of the shock-absorbing pad 14. The second spring 17 sleeved outside the second threaded rod 16 shocks the compression pump 5.

[0028] It should be noted that threads are provided on the outer side of the second threaded rod 16, and the second threaded rod 16 is screwed to the rotary handle 15.

[0029] It should be introduced that four groups of shock-absorbing pads 14, rotary handles 15, second threaded rods 16 and second springs 17 are provided and evenly arranged at the bottom end of the compression pump 5. By rotating the rotary handle 15 at the top end of the second threaded rod 16, the second spring 17 at the bottom end of the rotary handle 15, and simultaneously adjusting the other three groups of shock-absorbing devices, the vibration generated with the cleaning machine body 1 is reduced, and the generation of noise is reduced to a certain extent.

[0030] Among them, the motor 2 is a prior art and will not be described in detail; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are based on Figure 1 the direction shown in the drawing.

[0031] Working principle:

[0032] First, the staff places the cleaning machine body 1 on the ground, pulls out the cleaning gun 13 from inside the fixture 12 to clean the ground. When in use, the noise of the compression pump 5 is relatively large. Start the motor 2, and the output end of the motor 2 rotates the first threaded rod 3 clockwise. At this time, the first threaded rod 3 pushes the shock-absorbing box 4 to move to the right to cover the outside of the compression pump 5 and block the noise of the compression pump 5. Moreover, the shock-absorbing pad 14 at the bottom end of the compression pump 5 shocks the compression pump 5. By rotating the rotary handle 15 at the top end of the second threaded rod 16, the second spring 17 at the bottom end of the rotary handle 15, and simultaneously adjusting the other three groups of shock-absorbing devices, the vibration generated with the cleaning machine body 1 is reduced, and the generation of noise is reduced to a certain extent;

[0033] When the compression pump 5 works for a long time, high temperature is generated inside the shock absorption box 4. At this time, the motor 2 rotates counterclockwise, and the shock absorption box 4 slides to the left outside the compression pump 5. At this time, the second telescopic rod 19 inside the right side of the shock absorption box 4 and the third spring 20 sleeved outside squeeze the rotating door 18 on the outside. At this time, the rotating door 18 rotates and opens, and the hot air flows out from the inside of the shock absorption box 4. Finally, after the cleaning gun 13 is used up, the cleaning gun 13 is placed inside the fixture 12. The fixture 12 squeezes the first telescopic rod 10 on the outside and the first spring 11 on the outside to deform. The first spring 11 presses against the fixture 12 to clamp it, and there will be no shaking during transportation.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
