The filter plate 24 is movably connected to the wall surface of the symmetric rotating edges 23. The driving wheel 22 is driven by a motor, and the motor is electrically connected to a power source. This is an existing technology, so it will not be elaborated here.

[0031] As Figure 2 、 Figure 3 and Figure 4 shown, the installation structure is arranged in the cavity of the housing 20 and can install the filter plate 24 to the wall surface of the rotating edge 23. The installation structure includes: a connecting rod 30, a card slot 31, a locking block 36, a clamping block 37, and a locking groove 38. The connecting rod 30 is fixedly connected to the wall surface of the symmetric rotating edges 23. The card slot 31 is formed in the side wall surface of the connecting rod 30. The locking block 36 is movably connected to the wall surface of the connecting rod 30. The clamping block 37 is fixedly connected to the end of the filter plate 24. The locking groove 38 is formed in the top of the clamping block 37. The clamping block 37 can be inserted into the card slot 31.

[0032] As Figure 2 、 Figure 3 and Figure 4 shown, the card slots 31 are symmetrically formed on both side wall surfaces of the connecting rod 30. The connecting rod 30 is symmetrically and fixedly connected up and down between the symmetric rotating edges 23. The locking block 36 can enter the card slot 31. The clamping block 37 is a rectangular block. The card slot 31 can adapt to the size of the clamping block 37. The locking groove 38 is a rectangular groove. The locking block 36 can enter the locking groove 38. The clamping block 37 is clamped in the card slot 31. A magnetic block is fixedly installed at the top inside the card slot 31, and the magnetic block can adsorb the top of the locking block 36. The installation structure further includes a sliding groove 32, a through groove 33, a sliding block 34, and a connecting plate 35. The sliding grooves 32 are symmetrically formed at the bottom of the connecting rod 30. The through grooves 33 are also symmetrically formed at the bottom of the connecting rod 30. The sliding block 34 is slidably connected in the sliding groove 32. The connecting plate 35 is fixedly connected to the bottom of the sliding block 34. The locking block 36 is fixedly connected to the top of the connecting plate 35. The sliding block 34 is a T-shaped block, and the sliding groove 32 is a T-shaped groove. The sliding groove 32 can adapt to the vertical up and down sliding of the sliding block 34. The sliding grooves 32 are symmetrically formed at the front and back of the bottom of the connecting rod 30. The through grooves 33 are symmetrically formed on both sides of each sliding groove 32. The locking block 36 can penetrate through the through groove 33 and enter the card slot 31. A sliding block 34 is respectively arranged in each sliding groove 32. The same connecting plate 35 is arranged at the bottom of each sliding block 34. The locking blocks 36 are symmetrically arranged on both sides of the top of each connecting plate 35;

[0033] During specific use, the water to be filtered enters through the opening on the wall of the outer shell 20. At this time, the power supply of the motor is turned on. The motor can drive the driving wheel 22 to rotate when the power is on. The driving wheel 22 can contact the wall surface of the rotating edge 23 when rotating, and drive the rotating edge 23 to rotate in the cavity of the outer shell 20. The rotating edge 23 can drive the filter plate 24 to rotate. When the water flow passes through the rotating filter plate 24, it can be filtered through the filter grooves 25 and then discharged from the water outlet pipe 21 out of the cavity of the outer shell 20. When installing the filter plate 24, first insert the bottom of the filter plate 24 into the alignment groove 41, and then insert the clamping block 37 at the end of the filter groove 25 into the corresponding clamping groove 31. When the clamping block 37 is inserted into the clamping groove 31, it will push the connecting plate 35 upward. At this time, the top of the locking block 36 passes through the locking groove 38 and adsorbs to the magnet in the clamping groove 31. At this time, the installation of the filter plate 24 is completed. When it is necessary to disassemble the filter plate 24, just pull the connecting plate 35 downward so that the locking block 36 no longer enters the locking groove 38, then the clamping block 37 can be taken out of the clamping groove 31, and then the filter plate 24 can be removed;

[0034] In summary, by setting the installation structure, the filter plate 24 can be quickly installed into the cavity of the outer shell 20. Because the installation structure fixes the position of the filter plate 24 by clamping the clamping block 37 into the clamping groove 31 and then the locking block 36 into the locking groove 38 when installing the filter plate 24, compared with the prior art, this solution is more rapid and convenient when installing the filter plate 24.

[0035] As Figure 3 and Figure 5 shown, a reinforcement structure is also provided between the symmetric rotating edges 23. The reinforcement structure includes side rods 40, alignment grooves 41, first support rods 42 and second support rods 43. The side rods 40 are fixedly connected between the symmetric rotating edges 23. The alignment grooves 41 are opened on the wall surface of the side rods 40. The first support rods 42 are fixedly connected to the wall surface of the rotating edges 23. The second support rods 43 are fixedly connected to the wall surface of the first support rods 42. The side rods 40 are symmetrically arranged on both sides between the symmetric rotating edges 23. The alignment grooves 41 are symmetrically arranged on the upper and lower wall surfaces of the side rods 40. The alignment grooves 41 can be adapted to the bottom end of the filter plate 24. The first support rods 42 are respectively arranged on the wall surface of each rotating edge 23. The second support rods 43 are fixedly connected between the symmetric first support rods 42. The wall surface of the second support rods 43 can contact the inner arc of the filter plate 24;

[0036] During specific use, when the filter plate 24 is installed between the symmetric rotating edges 23 of the outer shell 20, the wall surface of the second support rod 43 will contact the filter plate 24, and the first support rod 42 will also contact the wall surface of the filter plate 24. When the filter plate 24 is stressed, the first support rod 42 and the second support rod 43 can be stressed simultaneously;

[0037] In summary, by setting the reinforcement structure, the compressive resistance of the filter plate 24 can be improved by sharing the force received by the filter plate 24. Since the filter plate 24 will be subjected to pressure and deformation after long-term operation, the second support rod 43 and the first support rod 42 can support the wall surface of the filter plate 24 to improve the compressive resistance of the filter plate 24 and extend its service life. Moreover, through the alignment groove 41, the position of the filter plate 24 can be initially fixed during the installation of the filter plate 24, facilitating the subsequent installation of the filter plate 24.

[0038] Working principle: The water to be filtered enters through the opening on the wall surface of the housing 20. At this time, the motor power supply is turned on. The motor can drive the driving wheel 22 to rotate when the power supply is turned on. The driving wheel 22 can contact the wall surface of the rotating edge 23 during rotation and drive the rotating edge 23 to rotate within the cavity of the housing 20. The rotating edge 23 can drive the filter plate 24 to rotate. When the water flow passes through the rotating filter plate 24, it can be filtered through the filter slots 25 and then discharged from the water outlet pipe 21 out of the cavity of the housing 20.
