[0041] like Figures 1 to 7 As shown, a filter assembly with anti-clogging function comprises:

[0042] An installation pipe 1, inside which a first filter screen 2 is detachably connected;

[0043] A debris removal component is rotatably connected to one side of the first filter screen 2, and the debris removal component is provided with a liquid inlet 3 and a first liquid discharge port 4;

[0044] A sealing member, disposed inside the impurity removal assembly, and fixedly connected to one side of the first filter screen 2;

[0045] A second liquid discharge port 5 is arranged on the outer wall of the mounting tube 1;

[0046] A driving member is fixedly mounted on the outer wall of the mounting tube 1, and a working end of the driving member passes through the mounting tube 1 and is drivingly connected to the impurity removal assembly;

[0047] The impurity removal component is driven to rotate by a driving member. When the liquid inlet 3 passes through the sealing member, the liquid inlet 3 is in a closed state, and the first liquid discharge port 4 is connected to the second liquid discharge port 5 to discharge the filter residue in the impurity removal component.

[0048] For example, the impurity removal component is driven to rotate by a driving member. When the liquid inlet 3 acts on the seal, the liquid inlet 3 is closed, and the first liquid discharge port 4 is connected with the second liquid discharge port 5 to ensure that the interior of the impurity removal component is in an empty state. At this time, the first filter screen 2 in the mounting tube 1 is used normally to perform impurity removal and filtering. After the liquid inlet 3 is separated from the seal, the liquid inlet 3 is connected with the mounting tube 1, and the liquid enters the impurity removal component. Impurities follow the flow of the liquid into the impurity removal component until the interior of the impurity removal component is filled. When the liquid inlet 3 acts on the seal again, the liquid with impurities in the impurity removal component is discharged through the first liquid discharge port 4 and the second liquid discharge port 5, thereby preventing impurities from accumulating on the first filter screen 2 and affecting the filtering effect of the first filter screen 2.

[0049] As an optional embodiment, both ends of the installation tube 1 are provided with connecting sleeves 6, each of the connecting sleeves 6 is fixedly connected to the installation tube 1, and each of the connecting sleeves 6 is provided with threads inside.

[0050] For example, by providing connecting sleeves 6 at both ends of the installation pipe 1 and providing threads inside the connecting sleeves 6, installation and removal with other pipes are facilitated.

[0051] As an optional embodiment, at least one limit block 7 is fixedly provided on the inner wall of the mounting tube 1, at least one arc-shaped groove 8 is provided on the outer wall of the first filter screen 2, and a socket 9 connected to one end of the arc-shaped groove 8 is provided on the side of the first filter screen 2 away from the impurity removal component, and the socket 9 is adapted to be arranged to match the limit block 7.

[0052] For example, the limiting block 7 , the arc groove 8 and the socket 9 are arranged so as to facilitate locking the first filter screen 2 in the installation tube 1 .

[0053] As an optional embodiment, a limiting ring 10 is fixedly disposed inside the installation tube 1 to prevent the first liquid discharge port 4 from being disconnected from the second liquid discharge port 5 .

[0054] For example, by providing the limiting ring 10, on the one hand, it is used to ensure that the first drain port 4 is aligned and connected with the second drain port 5, and on the other hand, it is used to prevent the first filter screen 2 from damaging the limiting block 7 during the installation process.

[0055] As an optional embodiment, the impurity removal component includes:

[0056] An annular slide rail 11 is fixedly arranged on one side of the first filter screen 2;

[0057] The annular box body 12 has one side sleeved on the annular slide rail 11 and sealed, the annular box body 12 is rotatably connected to the annular slide rail 11, the liquid inlet 3 is arranged on the side of the annular box body 12 away from the first filter screen 2, the first liquid discharge port 4 is arranged on the outer wall of the annular box body 12, and the annular box body 12 is transmission-connected to the driving member.

[0058] For example, the annular box 12 is driven to rotate by the driving member, and the liquid inlet 3 and the first liquid discharge port 4 are driven to rotate by the annular box 12. When the liquid inlet 3 acts on the sealing member, the first liquid discharge port 4 is connected with the second liquid discharge port 5, and the sewage with impurities sucked into the annular box 12 is discharged into the installation pipe 1, thereby avoiding the problem that the first filter screen 2 is easily blocked by impurities due to long-term use, thereby affecting the use effect.

[0059] As an optional embodiment, a right-angled triangle frame 13 is provided on the side of the annular box body 12 away from the first filter screen 2, a straight side of the right-angled triangle frame 13 covers the liquid inlet 3 and is fixedly connected to the annular box body 12, and both straight sides of the right-angled triangle frame 13 are connected to the liquid inlet 3.

[0060] For example, by setting a right-angled triangle frame 13, the opening direction of the right-angled triangle frame 13 is consistent with the rotation direction of the annular box 12, which is used to reduce the problem of low impurity removal effect caused by backflow caused by the water flow after the annular box 12 is filled with water, causing sewage to flow out from the liquid inlet 3.

[0061] As an optional embodiment, a brush 14 is provided inside the annular box 12 . The brush 14 is fitted on the first filter screen 2 , and both ends of the brush 14 are fixedly connected to the inner wall of the annular box 12 .

[0062] For example, by arranging the brush 14 in the annular box 12, it is used to avoid the problem that impurities are stuck on the first filter screen 2 and difficult to clean.

[0063] As an optional embodiment, the sealing member is a semi-annular blocking frame 15, one side of the semi-annular blocking frame 15 is fixed on the annular slide rail 11, the outer wall of the semi-annular blocking frame 15 is fitted on the inner wall of the annular box body 12, and the two ends of the semi-annular blocking frame 15 are connected to the interior of the annular box body 12.

[0064] For example, when the liquid inlet 3 rotates to the semi-annular blocking frame 15, a seal is formed, and the sewage in the installation pipe 1 cannot enter, so that the first filter 2 works to perform filtering treatment. After the treated impurities are separated from the semi-annular blocking frame 15 at the liquid inlet 3, the annular box 12 is connected to the installation pipe 1, and the sewage is poured into the annular box 12 through the liquid inlet 3, and the impurities treated by the first filter 2 enter the annular box 12 under the influence of the water flow until the liquid inlet 3 acts on the semi-annular blocking frame 15 again to form a seal. At this time, the sewage in the annular box 12 is discharged from the installation pipe 1 through the first drain port 4 and the second drain port 5 to avoid the influence of impurities on the first filter 2.

[0065] As an optional embodiment, the driving member includes:

[0066] The motor 16 is fixedly mounted on the outer wall of the mounting tube 1, and the output shaft of the motor 16 is passed through the interior of the mounting tube 1;

[0067] A mounting plate 17, disposed inside the mounting tube 1, wherein the center of the mounting plate 17 is fixedly connected to the output shaft of the motor 16;

[0068] A plurality of first tooth columns 18 are distributed in an annular array and fixed on the mounting plate 17;

[0069] A plurality of second tooth columns 19 are distributed in an annular array and fixed on the annular box body 12;

[0070] Part of the first tooth columns 18 and part of the second tooth columns 19 are meshed in a staggered arrangement, so that the mounting plate 17 drives the annular box body 12 to rotate.

[0071] For example, the motor 16 drives the mounting plate 17 to rotate, and the mounting plate 17 drives the first gear column 18 to rotate. The first gear column 18 engages with the second gear column 19 in an interlaced manner to drive the annular box 12 to rotate, thereby completing the work of removing impurities filtered by the first filter screen 2.

[0072] As an optional embodiment, the second liquid discharge port 5 is covered with a collecting box 20, and the collecting box 20 is fixedly connected to the mounting tube 1. The collecting box 20 is communicated with the second liquid discharge port 5, and a second filter screen 21 is provided inside the collecting box 20. One end of the second filter screen 21 passes through one side of the collecting box 20 and is fixedly provided with a handle 22. A pump body 23 is fixedly provided on one side of the collecting box 20, and one end of the pump body 23 is communicated with the bottom of the collecting box 20, and the other end is communicated with the mounting tube 1.

[0073] For example, in order to avoid water waste, the sewage enters the collection box 20 through the second drain port 5 and is filtered twice through the second filter screen 21, and the filter density of the second filter screen 21 is less than the filter density of the first filter screen 2, further improving the separation of impurities and water. The filtered water is located at the bottom of the collection box 20, and the pump body 23 is used to introduce the filtered water at the bottom of the collection box 20 into the installation pipe 1. After the second filter screen 21 is used for a long time, the motor 16 can be shut down to make the liquid inlet 3 in a sealed state. At this time, the operation of the first filter screen 2 is not affected. Then the second filter screen 21 is taken out of the collection box 20 through the handle 22 for easy cleaning without affecting use.

[0074] Those skilled in the art should understand that the discussion of any of the above embodiments is only exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
