[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] The following is an explanation of the preferred embodiments of the device of the utility model.

[0032] See also Figure 1-8 As shown, the filtering water purifier with water pressure driven automatic scraping function includes a filter bottle 1, a cylindrical end cover 2 is fixedly connected to the top of the filter bottle 1, a manual valve 3 is fixedly connected to the top of the cylindrical end cover 2, the manual valve 3 is used to control the switch of the water purifier and the direction of water flow, the inside of the cylindrical end cover 2 and the bottom of the manual valve 3 are threadedly connected with a water flow bogie 4, an impeller frame 5 is arranged below the water flow bogie 4, a plurality of impellers 501 are evenly arranged on the impeller frame 5, a filter mesh frame 6 is arranged at the bottom of the water flow bogie 4, a filter element mounting ring 7 is installed on the inner side wall of the filter mesh frame 6 through a connecting ring body 13, a connecting inner ring 8 is threadedly connected to the bottom of the filter element mounting ring 7, a filter housing 9 is placed inside the filter bottle 1, a filter element cylinder 11 is arranged inside the filter housing 9, and a filter mesh 10 is arranged between the filter element cylinder 11 and the filter housing 9.

[0033] The interior of the filter bottle 1 can be equipped with filter cartridge bodies 11 of different diameters.

[0034] like Figure 4As shown, a plurality of first penetration holes 901 are evenly provided on the outer peripheral wall of the filter housing 9, a lower cover 902 is threadedly connected to the bottom of the filter housing 9, and a positioning seat 903 is provided at the center of the lower cover 902, a second penetration hole 1101 is provided on the outer peripheral wall of the filter element cylinder 11, a ring cover 1102 is installed at the bottom of the filter element cylinder 11, and a PP cotton filter element is provided inside the filter element cylinder 11. Specifically, after the tap water passes through the water flow bogie 4 and the impeller frame 5, it will enter the filter housing 9 and the filter element cylinder 11, and flow out after preliminary and fine filtration. The scraper on the rotating impeller frame 5 will scrape the inner wall of the filter housing 9 and the filter element cylinder 11 and the filter screen 10 to effectively remove attached impurities. This scraping action effectively removes impurities attached to the filter medium and the inner wall, thereby ensuring the filtering effect and the continuous and efficient operation of the water purifier. The first permeable hole 901 on the filter housing 9 and the second permeable hole 1101 on the filter cartridge body 11 allow water to flow through while trapping impurities.

This design makes the maintenance of the water purifier simpler and more intuitive. The user can flexibly adjust the sewage discharge time according to the actual situation, extend the service life of the filter element, and use the water pressure of the tap water itself to drive the impeller 501 to rotate, without the need for additional energy, thereby achieving the purpose of energy saving and environmental protection.

[0036] like Figure 5 As shown, the water flow bogie 4 includes a plurality of oblique blades 401 for changing the flow direction of tap water, an outer ring body 402, an inner ring body 403 and a support plate 404. The outer ring body 402 is embedded in the cylindrical end cover 2. The inner ring body 403 is provided on the coaxial inner side of the outer ring body 402. The outer wall of the inner ring body 403 is provided with a support plate 404. The number of the support plates (404) uniformly provided on the outer wall of the inner ring body 403 in the radial direction is consistent with the number of the blades (401).

[0038] like Figure 6-7 As shown, the manual valve 3 includes a valve body cover 301 and a valve body 302, a plurality of clamping strips 3011 are provided on the inner periphery of the valve body cover 301, and a block-shaped groove 3012 is opened in the center of the valve body cover 301, a water inlet 3021 and a clean water outlet 3022 are symmetrically provided on both sides of the valve body 302, and gaskets 3023 are sleeved on the opposite sides of the water inlet 3021 and the clean water outlet 3022, an internal thread connection part 3024 is provided at the bottom of the valve body 302, and the internal thread connection part 3024 is threadedly connected to the top of the water flow bogie 4, the clamping slot 3025 and the connecting block 3026 are installed in cooperation with the clamping strip 3011 and the block-shaped groove 3012, a connecting block 3026 is provided on the top of the valve body 302 corresponding to the block-shaped groove 3012, and a clamping slot 3025 is opened on the side of the valve body 302 corresponding to the clamping strip 3011.

[0039] Working principle: First, tap water enters the manual valve 3 from the water inlet 3021. Under the water pressure of the tap water itself, the water flows through the water bogie 4, changes the direction of the water flow at a certain inclination angle, and drives the impeller 501 to rotate, thereby automatically scraping the inner wall of the water purifier and the filter 10. Then the sewage is discharged through the sewage outlet 103, and the purified water flows into the PP cotton filter element through the filter 10. The water quality of the filter element can be easily checked through the transparent window 101 to decide when to discharge the sewage.
