[0018] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0019] like Figures 1 to 4As shown, a tap water filtering device described in the utility model comprises a housing 1, the housing 1 is a cylindrical structure, a filter cartridge 2 is rotatably arranged inside the housing 1, the diameter of the filter cartridge 2 is smaller than the inner diameter of the housing 1, a sealing plate 3 matching the inner diameter of the housing 1 is arranged at one end of the filter cartridge 2, the filter cartridge 2 is coaxially arranged with the sealing plate 3, and is rotatably arranged on the sealing plate 3, a water inlet 4 is opened on the sealing plate 3 at the outer edge of the filter cartridge 2, so that water flows into the gap between the housing 1 and the filter cartridge 2 through the water inlet 4, and the water flow is filtered; the end of the filter cartridge 2 away from the sealing plate 3 is open, and the outer circumference thereof is sealed with the inner diameter of the housing 1 to ensure that the water flows out from the open place, and the open end is connected with the flange 5 arranged on the housing 1. The utility model uses the outer arc side of the filter cartridge 2 to filter the water flow, which greatly increases the filtering area and improves the filtering efficiency, and at the same time provides a larger storage space for impurities, reduces the frequency of cleaning impurities, significantly reduces the work intensity, and enhances the practicality of the utility model.

[0020] Furthermore, a support ring 6 is provided at one end of the filter cartridge 2 away from the sealing plate 3. The support ring 6 extends to the outside of the housing 1 and is rotatably connected to the housing 1 and the corresponding flange 5 respectively. The rotatable connection is sealed to ensure its sealing performance. A cleaning brush 7 is provided inside the housing 1. The bristles of the cleaning brush 7 are in contact with the outer wall of the filter cartridge 2. The cleaning brush 7 is arranged along the axis of the filter cartridge 2. A closable sewage outlet 8 is provided at the bottom of the housing 1. The sewage outlet 8 is preferably provided at one end close to the open end of the filter cartridge 2. After long-term use, the filter cartridge 2 can be driven to rotate by rotating the support ring 6. With the frictional contact between the filter cartridge 2 and the cleaning brush 7, impurities attached to the filter cartridge 2 will be removed, thereby achieving the purpose of cleaning the filter cartridge 2 and ensuring the filtering effect. The closable setting of the sewage outlet 8 is used to remove the cleaned impurities from the housing 1.

[0021] Furthermore, a sealing plate 9 is provided inside the support ring 6 to seal it, and a sealing baffle 10 is provided at the outlet of the corresponding flange 5 to seal the outlet of the flange 5; the sealing baffle 10 and the sealing baffle 9 are rotatably abutted against each other, and water outlets 11 are correspondingly penetrated and opened on the sealing baffle 10 and the sealing baffle 9, and the water outlets 11 are arranged at intervals. During operation, as the filter cartridge 2 rotates, the water outlets 11 are displaced from each other, and the opening and closing of the water outlets 11 can be realized, so that after cleaning the filter cartridge 2, the water outlets 11 can be closed, and the impurities can be smoothly flushed out of the housing 1 by the supply of tap water, and discharged through the sewage outlet 8, thereby improving the convenience of cleaning the impurities. Preferably, the water outlet 11 is provided with two groups, inner and outer, along the axis of the filter cartridge 2, and the two groups of water outlets 11 are arranged in a vertical state, and the two water outlets 11 in each group are arranged symmetrically, so that the arrangement can not only increase the flow rate of the water outlet, but also ensure the smooth closure of the water outlet 11 when the impurities are discharged, thereby enhancing the practicality of the utility model.

[0022] Furthermore, a positioning member is provided between the support ring 6 and the corresponding flange 5 to ensure the stability of the filter cartridge 2 during operation; specifically, the positioning member includes a positioning plate 12 arranged on the flange 5, a positioning bolt 13 is threadedly provided on the positioning plate 12, and a positioning screw hole is provided on the support ring 6; because the flange 5 is connected to a fixed water supply pipeline during use, the positioning of the support ring 6 can be achieved by connecting the positioning bolt 13 with the positioning screw hole, thereby ensuring the stability of the filter cartridge 2.

[0023] Furthermore, in the present embodiment, a sewage pipe 14 is provided downwardly extending from the sewage outlet 8, and a valve is provided on the sewage pipe 14; a water inlet pipe 15 is also provided on the side of the top of the shell 1 close to the sealing plate 3, and a valve is provided on the water inlet pipe 15. The setting of the water inlet pipe 15 allows the impurities in the shell 1 to be cleaned by flushing water without opening the valve connected to the water tank, and the impurities can be cleaned by using an external water source to be poured into the shell 1 through the water inlet pipe 15, thereby improving the controllability of the operation and enhancing the practicality of the present invention.

[0024] When the utility model is in use, the flanges 5 at both ends are respectively connected to the water inlet of the water tank and the inlet of the water pipeline. As the water tank valve switch is turned on, water flows from the water inlet 4 into the gap between the filter cartridge 2 and the inner wall of the shell 1, and is discharged from the other end of the filter cartridge 2 to the water pipeline after being filtered by the filter cartridge 2, thereby realizing the transportation of purified water. When the filter cartridge 2 needs to be cleaned, the contact is positioned to position the support ring 6, and the support ring 6 is rotated to drive the filter cartridge 2 to rotate, and finally the impurities are flushed out from the sewage outlet 8 by the water flow. The operation is simple, fast and practical.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
