During the rotation of the sealing cover 3, the turntable 14 will rotate inside the fixing groove 13, and then the sealing cover 3 can be fixed on the surface of the top end of the water inlet 2, and then the water in the fish pond will enter the inside of the filter cartridge 1 from the water inlet 2, and then the water will pass through the inside of the filter hole 6, and the larger impurities in the water will be blocked by the filter screen 5, and then the filter cotton inside the filter screen 5 will perform secondary filtration on the pool water, thereby increasing the filtering effect of the equipment;

[0027] When the filter cotton needs to be removed, the handle 15 and the sealing cover 3 can be rotated in the opposite direction, and then the insertion rod 17 can be pulled out from the inside of the slide groove 4, and then the compressed spring 10 will push the extrusion rod 11 and the contact block 12 to move, and then the contact block 12 will push the filter screen 5 and the fixing ring 8 to move, and then the filter screen 5 will drive the connecting block 7 to move upward inside the slide groove 4, and then the operator can take out the filter screen 5 and the filter cotton, and then clean them.

[0028] like Figure 4 and Figure 7 As shown, a threaded strip 18 is fixedly mounted on the inner surface of the sealing cover 3 , and a threaded groove 19 is provided on the top of the surface of the filter cartridge 1 .

[0029] The above scheme is adopted: through the design of the thread bar 18 and the thread groove 19, when the sealing cover 3 is put on the surface of the water inlet 2, the sealing cover 3 can be rotated, and then the surface of the thread bar 18 will enter the inside of the thread groove 19, and then the sealing cover 3 can be fixed on the surface of the water inlet 2.

[0030] like Figure 5 As shown, a second fixing groove 21 is fixedly opened inside the vertical rod 9, and a baffle 22 is fixedly sleeved on the bottom end of the surface of the extrusion rod 11. The baffle 22 is circular in design, and the surface of the baffle 22 fits the inner wall of the second fixing groove 21. The diameters of the baffle 22 and the second fixing groove 21 are larger than the diameter of the extrusion rod 11.

[0031] The above scheme is adopted: through the design of the second fixing groove 21 and the baffle 22, when the extrusion rod 11 moves, the baffle 22 will move inside the second fixing groove 21, and the diameter of the baffle 22 and the second fixing groove 21 is larger than the diameter of the extrusion rod 11, thereby blocking the extrusion rod 11 and preventing the extrusion rod 11 from moving out of the vertical rod 9.

[0032] like Figure 5 As shown, a sealing groove 23 is provided at the top end of the vertical rod 9 , and a sealing ring 24 is provided inside the sealing groove 23 and located on the surface of the extrusion rod 11 .

[0033] The above scheme is adopted: through the design of the sealing groove 23 and the sealing ring 24, when the extrusion rod 11 moves, it can move inside the sealing ring 24, and then the sealing of the vertical rod 9 can be increased to prevent pool water from entering the interior of the vertical rod 9, and the inner wall of the sealing ring 24 contacts the surface of the extrusion rod 11, thereby increasing the damping effect between the extrusion rod 11, and then when the spring 10 is reset, the extrusion rod 11 can be pushed to reset smoothly.

[0034] like Figure 1 As shown, a handle 15 is fixedly mounted on the top of the sealing cover 3, and the handle 15 is U-shaped.

[0035] With the above solution, the operator can hold the handle 15 by hand through the design of the handle 15 , thereby facilitating the operator to move and set the seal cover 3 .

[0036] like Figure 1 As shown, a water outlet 20 is provided at the top of the surface of the filter cartridge 1 . There are several water outlets 20 , which are evenly distributed on the surface of the filter cartridge 1 .

[0037] The above solution is adopted: through the design of the water outlet 20, after the pool water is filtered, it can flow out from the inside of the water outlet 20. Since there are several water outlets 20, the water can be drained more smoothly.

[0038] like Figure 2 As shown, the opposite side of the insertion rod 17 is designed to be arc-shaped, there are two insertion rods 17, and the insertion rods 17 are designed to be longitudinally symmetrical about the center of the filter cartridge 1.

[0039] The above solution is adopted: through the design of the plug rod 17, since the opposite side of the plug rod 17 is designed to be arc-shaped and the surface is in contact with the inside of the slide groove 4, the aesthetics of the equipment is ensured, and the two plug rods 17 push the filter screen 5 to move at the same time, thereby allowing the filter screen 5 to move smoothly.

[0040] The working principle and use process of this utility model:

[0041] First, the operator can put the filter cotton into the filter screen 5, and then put the filter screen 5 into the filter cartridge 1. Then, the sealing cover 3 can be put on the surface of the water inlet 2, and the insertion rod 17 can be inserted into the inside of the slide groove 4. Then, the insertion rod 17 will push the connecting block 7 and the filter screen 5 to move, and then the fixing ring 8 will push the contact block 12 to move. When the contact block 12 moves, it will drive the squeezing rod 11 to squeeze the spring 10, and then the handle 15 and the sealing cover 3 can be turned, and then the threaded strip 18 will enter the inside of the threaded groove 19, and then the sealing cover 3 can be fixed on the surface of the filter cartridge 1.

[0042] After the fixing is completed, water can enter the interior of the filter cartridge 1 through the water inlet 2, and then the water will pass through the filter hole 6, and the larger impurities in the water will be blocked by the filter mesh 5, and then the filter cotton inside the filter mesh 5 will perform a secondary filtration on the water, thereby increasing the filtering effect;

[0043] When the filter cotton needs to be removed, the handle 15 and the sealing cover 3 can be rotated in the opposite direction, and then the threaded strip 18 will move away from the inside of the threaded groove 19, and then the insertion rod 17 can be pulled out from the inside of the slide groove 4. When the bottom end of the insertion rod 17 moves away from the top end of the connecting block 7, the compressed spring 10 will push the extrusion rod 11 and the contact block 12 to move upward, and then the contact block 12 will push the filter screen 5 and the fixing ring 8 to move upward, and then the filter screen 5 will move out of the interior of the filter cartridge 1, and then the operator can take out the filter screen 5, and then the filter screen 5 and the filter cotton can be cleaned.
