A filtering device 7 is arranged on one side of the connecting shell 6. The filtering device 7 is used to filter some impurities in the water. The size of the impurities filtered is related to the filter holes. The filtering device 7 includes a first filter 8 and a second filter 9. The first filter 8 is used to filter larger objects. The second filter 9 can adjust the size of the total filter holes. The first filter 8 and the second filter 9 are both arranged on one side of the water pump shell. The second filter 9 is arranged inside the first filter 8. The second filter 9 ensures that there will be no larger objects inside.

[0032] The first filter 8 includes a fixing ring 11, a fixing rod 12 and a connecting ring 13. The fixing ring 11 is sleeved on one side of the connecting shell 6 and is threadedly connected thereto. The fixing ring 11 is used for fixing. Water will flow in from between the multiple fixing rods 12, and large objects will be blocked outside the fixing rods 12. The multiple fixing rods 12 are evenly fixedly connected to the fixing ring 11, thus forming a first filter 8 similar to a cylindrical shape. The connecting ring 13 is fixedly connected to one end of the multiple fixing rods 12. The connecting ring 13 is used to connect the fixing rods 12 together to ensure that they are relatively stable and strong.

The first filter 8 can directly install the fixing ring 11 on the connecting shell 6, and finally install the rotating ring 18 to adjust the size of the filter hole for use.

[0034] Embodiment 2

[0035] See also Figure 3 - Figure 5 On the basis of the first embodiment, the second filter 9 includes a rotating ring 18, an outer cylinder 15, an inner cylinder 16 and a mounting ring 22. The mounting ring 22 is fixedly connected to one side of the connecting shell 6. The mounting ring 22 is the key to installing the entire second filter 9. By installing the mounting ring 22 on the connecting shell 6, the inner cylinder 16 is fixedly connected to the mounting ring 22, so that the inner cylinder 16 can be indirectly connected to the connecting shell 6. The outer cylinder 15 is rotatably sleeved on the inner cylinder 16. The outer cylinder 15 and the inner cylinder 16 can not only rotate but also slide. One end of the inner cylinder 16 is fixedly connected to a fixing column 19. One end of the inner cylinder 16 is opened and the other end is closed. A fixing column 19 is fixedly connected to the outside of the closed end. The fixing column 19 is used to fix the outer cylinder 15. The fixing column 19 passes through one end of the outer cylinder 15 and is rotatably connected thereto. The outer cylinder 15 is slightly larger than the inner cylinder 16, so the outer cylinder 15 can be sleeved on the inner cylinder 16. The rotating ring 18 is sleeved on the fixing column 19. The rotating ring 18 and the fixing column 19 are threadedly connected. When the rotating ring 18 rotates to a certain extent, the rotating ring 18 and the outer cylinder 15 will fit tightly together and make the outer cylinder 15 squeeze one end of the inner cylinder 16.

[0036] An annular groove 24 is provided on one side of the mounting ring 22, and the opening of the annular groove 24 is arranged in the direction of the outer cylinder 15. A snap ring 20 is installed on one side of the outer wall of the annular groove 24, and the snap ring 20 is used to clamp the limiting ring 27 on the outer cylinder 15 in the annular groove 24. The inner diameter of the snap ring 20 is slightly larger than the outer diameter of the outer cylinder 15 but much smaller than the outer diameter of the limiting ring 27. At the same time, the inner diameter of the annular groove 24 is slightly smaller than the inner diameter of the outer cylinder 15, and the outer diameter of the annular groove 24 is slightly larger than the outer diameter of the limiting ring 27, so that the limiting ring 27 and the outer cylinder are fixed to each other. One end of the outer tube 15 can slide a small distance back and forth in the annular groove 24, and can also rotate in the annular groove 24. When the rotating ring 18 is rotated to fit it tightly, the outer tube 15 can no longer rotate relative to the inner tube 16. A plurality of screws 21 are provided on the snap ring 20. The screws 21 are used to fix the snap ring 20 and the mounting ring 22. The plurality of screws 21 all penetrate the side walls of the snap ring 20 and the annular groove 24 and are threadedly connected to the connecting shell 6. The screws 21 will extend into the screw hole 10 and be threadedly connected thereto.

[0037] One end of the outer cylinder 15 is fixedly sleeved with a limit ring 27, and the limit ring 27 is used to limit the outer cylinder 15 and the inner cylinder 16 from being easily separated. One end of the outer cylinder 15 fixedly sleeved with the limit ring 27 extends into the annular groove 24 and is rotatably connected thereto. When the rotating ring 18 is loosened, the outer cylinder 15 can slide relative to the inner cylinder 16, but the sliding distance is short, so that the outer cylinder 15 can be fixed by the rotating ring 18. The side wall of the inner cylinder 16 is evenly provided with a plurality of inner filter holes 26, and the length of the outer filter holes 17 is slightly larger than the length of the inner filter holes 26. The side wall of the outer cylinder 15 is evenly provided with a plurality of outer filter holes 17, and the plurality of outer filter holes 17 can correspond one-to-one with the plurality of inner filter holes 26 to form a total filter hole.

[0038] In actual use, first loosen the rotating ring 18, move the outer cylinder 15 so that the filter holes between the inner and outer cylinders 15 are separated to a certain extent, and the size of the combined filter holes is set according to needs. When it reaches a suitable combined filter hole, it is necessary to press the outer cylinder 15 and rotate the rotating ring 18 to fix the inner cylinder 16 and the outer cylinder 15 together. The two can no longer rotate or slide relative to each other. Finally, there will be multiple outer filter holes 17 that can correspond one-to-one with multiple inner filter holes 26 to form a total filter hole.

[0039] Embodiment 3

[0040] See also Figure 2 and Figure 7On the basis of the second embodiment, the outer wall of the rotating ring 18 is fixedly and evenly connected with a plurality of raised blocks 25, and the arrangement of the plurality of raised blocks 25 is to ensure that there is no slipping during manual rotation. A water inlet 29 is provided on one side of the connecting shell 6, and the water inlet 29 is used to suck the filtered water from the filter device 7. A plurality of screw holes 10 are evenly provided on the side wall of the water inlet 29, and the screw holes 10 are used to fix the filter device 7. A connecting cylinder 28 is threadedly connected to the inner wall of the mounting ring 22. When the filter needs to be cleaned, the connecting cylinder 28 can be removed and cleaned separately, so that the cleaning is cleaner. One end of the connecting cylinder 28 extends into the water inlet 29 and is slidably connected thereto. The connecting cylinder 28 is used to send the filtered water into the water inlet 29 to prevent leakage from the gap at the connection.

[0041] In actual use, a filter and installation method for preventing water pump from blocking is provided. In actual installation, first install the second filter 9, sleeve the outer cylinder 15 on the inner cylinder 16, and fully extend the end of the outer cylinder 15 with the limiting ring 27 into the annular groove 24, sleeve the clamping ring 20 on the outer cylinder 15, and then install the connecting cylinder 28 on one end of the inner cylinder 16, and finally penetrate the clamping ring 20 and the mounting ring 22 through the screw and extend it into the screw hole 10 to be threadedly connected with it, so that the second filter 9 can be fixed, and then the first filter 8 is installed. The first filter 8 directly fixes the fixing ring 1 1 can be installed on the connecting shell 6, and finally the rotating ring 18 is installed to adjust the size of the filter hole for use. In actual use, first loosen the rotating ring 18, and move the outer cylinder 15 so that the filter holes between the inner and outer cylinders 15 are separated to a certain extent. The size of the combined filter hole is set according to needs. When it reaches a suitable combined filter hole, it is necessary to press the outer cylinder 15 and rotate the rotating ring 18 so that the inner cylinder 16 and the outer cylinder 15 are fixed together. The two can no longer rotate or slide relative to each other. Finally, there will be multiple outer filter holes 17 that can correspond to multiple inner filter holes 26 one by one to form a total filter hole.
