[0034] like Figure 8 As shown, the container 1 is equipped with a filter mechanism 4 for filtering impurities in the water. The filter mechanism 4 includes a filter screen 401 inside the container 1. A through groove is provided on the container 1. A second rotating shaft 402 is movably connected inside the container 1 via a bearing. A connecting ring 403 is fixedly provided at the bottom end of the second rotating shaft 402. The bottom end of the second rotating shaft 402 is movably connected to the top of the filter screen 401 via a bearing. Two scrapers 404 are provided outside the connecting ring 403. The bottom of the scrapers 404 contacts the top of the filter screen 401. The top end of the second rotating shaft 402 passes through the container 1 and extends out of the top of the container 1. A second motor 405 is fixedly provided at the top end of the second rotating shaft 402.

[0035] like Figure 6 , 7 As shown, the container 1 is provided with a collection mechanism 6 for cleaning the filtered impurities. The collection mechanism 6 includes a first connecting plate 601 provided on the outside of the container 1. A collection bucket 602 is sleeved on the outside of the first connecting plate 601. Multiple threaded holes 603 are provided on both the first connecting plate 601 and the collection bucket 602. The same bolt 604 is threaded into two connected threaded holes 603. A bucket cap 605 is threaded to the top of the collection bucket 602. Handles 5 are fixed on both sides of the collection bucket 602.

[0036] Water enters the container 1 through the inlet pipe 8. The filter screen 401 inside the container 1 can clean impurities in the water, preventing impurities from clogging the regulating mechanism 3 and improving the water pressure regulation efficiency. The second motor 405 is started, which can drive the second rotating shaft 402 to rotate. The rotation of the second rotating shaft 402 drives the connecting ring 403 to rotate. The rotation of the connecting ring 403 can drive the scraper 404 to move. The scraper 404 cleans the impurities on the filter screen 401. The impurities slide down the filter screen 401 into the collection tank 602. The collection tank 602 can collect the impurities for centralized treatment.

[0037] Turn the bolt 604 to unscrew it from the two threaded holes 603, pull the handle 5, and use the handle 5 to remove the collection bucket 602 from the container 1. Then turn the bucket cap 605 to remove it from the collection bucket 602, so that the impurities can be poured out from the collection bucket 602 for easy cleaning.

[0038] like Figure 4 As shown, the adjustment mechanism 3 includes a connecting pipe 301 communicating with one side of the water outlet pipe 2. A sealing plug 302 is provided inside the connecting pipe 301. A control box 303 is fixedly provided at the top of the connecting pipe 301. A connecting rod 304 is fixedly provided at the top of the sealing plug 302. The top end of the connecting rod 304 passes through the control box 303 and extends into the control box 303.

A first motor 307 is fixedly provided at the bottom end of the first rotating shaft 305.

[0039] The filtered water enters the connecting pipe 301 through the inlet pipe 2. The first motor 307 is started, which drives the first rotating shaft 305 to rotate. Under the action of the two first gears 306, the first rotating shaft 305 drives the connecting rod 304 to rotate. The rotation of the connecting rod 304 drives the sealing plug 302 to rotate. By adjusting the rotation angle of the sealing plug 302, the flow rate of the water inside the connecting pipe 301 can be adjusted and the water pressure controlled. Compared with the manual adjustment method in the prior art, the operation of this utility model is simple and the safety is improved.

[0040] like Figure 5 As shown, the control box 303 is provided with a fixing mechanism 7 for fixing the sealing plug 302. The fixing mechanism 7 includes a limiting plate 701 provided outside the connecting rod 304. A threaded cylinder 702 is movably connected inside the control box 303 through a bearing. The top end of the threaded cylinder 702 passes through the control box 303 and extends out of the top of the control box 303. A threaded rod 703 is threadedly connected inside the threaded cylinder 702. Multiple insertion holes 704 are provided on the limiting plate 701. The threaded rod 703 is adapted to the insertion holes 704.

[0041] like Figure 5 As shown, a third rotating shaft 705 is movably connected inside the control box 303 via bearings. A second gear 706 is provided through the bottom end of the threaded cylinder 702 and the top end of the third rotating shaft 705. The two second gears 706 mesh with each other. A third motor 707 is fixedly provided at the bottom end of the third rotating shaft 705.

[0042] After adjusting the rotation angle of the sealing plug 302, start the third motor 707. The third motor 707 can drive the third rotating shaft 705 to rotate. Under the action of the two second gears 706, the third rotating shaft 705 can drive the threaded cylinder 702 to rotate. The rotation of the threaded cylinder 702 can drive the threaded rod 703 to move downward, inserting the threaded rod 703 into the insertion hole 704. The threaded rod 703 can limit the limit plate 701, preventing the sealing plug 302 from rotating and improving stability.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
