[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The self-cleaning water purifier filter device can rotate the linkage rod by setting a handle, thereby rotating the movable plate. When the movable plate is located above the water inlet pipe, the filter device is in a filtering state, and when the movable plate is located below the water inlet pipe, the filter device is in a self-cleaning state.

[0015] The self-cleaning water purifier filter device, when in the filtering state, water enters the interior of the machine body from the bottom of the movable plate, is filtered through the filter net and then discharged from the drain pipe. When in the self-cleaning state, water enters the interior of the machine body from the top of the movable plate, so the water is first located on the side of the filter net close to the drain pipe, then passes through the filter net and flushes the filter net, and the sewage is discharged through the sewage pipe.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4In the present embodiment, a self-cleaning water purifier filter device comprises a body 1, a filter screen 101 is connected inside the body 1, a mounting block 102 is connected to one side of the filter screen 101, a rotating rod 103 is connected to one side of the mounting block 102, a movable plate 104 is connected to the outside of the rotating rod 103, a linkage rod 105 is connected to one side of the movable plate 104, a sealing ring 106 is connected inside the body 1, a water inlet pipe 2 is connected to one side of the body 1, a first valve 201 is connected to one end of the water inlet pipe 2, a drain pipe 3 is connected to the other side of the body 1, a second valve 301 is connected to one end of the drain pipe 3, a sewage pipe 4 is connected below the body 1, a third valve 401 is connected to one end of the sewage pipe 4, and a handle 5 is arranged on the outside of the body 1.

[0023] In the case implementation, the lower end of the filter 101 is connected to the inner bottom wall of the body 1, and the upper end of the filter 101 does not contact the inner top wall of the body 1. The mounting block 102 is located on the side of the filter 101 close to the water inlet pipe 2. The rotating rod 103 is rotatably connected to the movable plate 104. Both ends of the movable plate 104 are arc-shaped. The two ends of the movable plate 104 are respectively fitted with the filter 101 and the inner wall of the body 1, so that one side of the movable plate 104 is located above the water inlet pipe 2. At this time, the first valve 201 and the second valve 301 are in an open state, and the third valve 401 is in a closed state. Therefore, water enters the interior of the body 1 from the water inlet pipe 2 and is located below the movable plate 104. After being filtered through the filter 101, it is discharged from the drain pipe 3.

[0024] In the case implementation, the linkage rod 105 passes through the sealing ring 106, and the linkage rod 105 is connected to the handle 5. The linkage rod 105 can be rotated by rotating the handle 5, so that the movable plate 104 rotates. When the movable plate 104 is located above the water inlet pipe 2, the filter device is in a filtering state. When the movable plate 104 is located below the water inlet pipe 2, the filter device is in a self-cleaning state.

[0025] In the case implementation, the sewage pipe 4 is located at the central position below the body 1, the lower end of the body 1 is arc-shaped, the filter screen 101 is located on one side of the sewage pipe 4, so that the movable plate 104 is located below the water inlet pipe 2. At this time, the first valve 201 and the third valve 401 are in an open state, and the second valve 301 is in a closed state, so water enters the interior of the body 1 from the water inlet pipe 2, and is located above the movable plate 104, on the side of the filter screen 101 close to the drain pipe 3, passes through the filter screen 101, and flushes the filter screen 101, and the sewage is discharged through the sewage pipe 4.

[0026] When implementing, follow these steps:

[0027] 1) First, turn the handle 5 so that one side of the movable plate 104 is located above the water inlet pipe 2, and the first valve 201 and the second valve 301 are in an open state, and the third valve 401 is in a closed state;

[0028] 2) Then the water enters the interior of the machine body 1 from the bottom of the movable plate 104, passes through the filter screen 101 and is discharged from the drain pipe 3;

[0029] 3) Turn the handle 5 again so that the movable plate 104 is located below the water inlet pipe 2, and the first valve 201 and the third valve 401 are in an open state, and the second valve 301 is in a closed state;

[0030] 4) Finally, water enters the interior of the machine body 1 from the top of the movable plate 104 , and then the water is first located on the side of the filter 101 close to the drain pipe 3 , and then passes through the filter 101 and flushes the filter 101 , and the sewage is discharged through the drain pipe 4 .

[0031] In summary, the self-cleaning water purifier filter device can rotate the linkage rod 105 by rotating the handle 5, thereby rotating the movable plate 104. When the movable plate 104 is located above the water inlet pipe 2, the filter device is in a filtering state. At this time, the first valve 201 and the second valve 301 are in an open state, and the third valve 401 is in a closed state. Therefore, water enters the interior of the body 1 from the water inlet pipe 2 and is located below the movable plate 104. After being filtered through the filter net 101, it is discharged from the drain pipe 3.

[0032] Furthermore, by rotating the handle 5, the linkage rod 105 can be rotated, thereby rotating the movable plate 104. When the movable plate 104 is located below the water inlet pipe 2, the filtering device is in a self-cleaning state. At this time, the first valve 201 and the third valve 401 are in an open state, and the second valve 301 is in a closed state. Therefore, water enters the interior of the machine body 1 from the water inlet pipe 2, and is located above the movable plate 104, on the side of the filter screen 101 close to the drain pipe 3, passes through the filter screen 101, and flushes the filter screen 101. The sewage is discharged through the sewage pipe 4, which has the advantage of easy cleaning.
