[0036] Furthermore, the outer wall of the card block 23 fits into the inner wall of the card slot 19, so that when the card block 23 enters the card slot 19, the box door 16 can be fixed in place.

[0037] The effect achieved by the entire embodiment 2 is that during installation, the operator replaces the corresponding size of the connecting pipe 5 according to the diameter of the inlet pipe 6, inserts the insert plate 28 into the slot 25, and when the top of the connecting pipe 5 is in contact with the bottom of the outlet pipe 4, the connecting groove 29 moves to the side of the connecting block 32. The operator rotates the handle 31, the second threaded rod 30 rotates, the second threaded rod 30 moves along the threaded hole 27, and thus drives the connecting block 32 to move. The connecting block 32 enters the connecting groove 29, and the installation is completed in this way, which makes it convenient to replace the corresponding size of the connecting pipe 5 according to different diameters of the inlet pipe 6.

[0038] Working principle: During installation, the operator replaces the connecting pipe 5 with the corresponding size according to the diameter of the inlet pipe 6, inserts the insert plate 28 into the slot 25, and when the top of the connecting pipe 5 is in contact with the bottom of the outlet pipe 4, the connecting groove 29 moves to the side of the connecting block 32. The operator rotates the handle 31, the second threaded rod 30 rotates, and the second threaded rod 30 moves along the threaded hole 27, thereby driving the connecting block 32 to move and enter the connecting groove 29. This completes the installation and facilitates the replacement of the corresponding size connecting pipe 5 according to different diameters of the inlet pipe 6. Then, the operator inserts the moving plate 37 into the storage groove 41. The inclined surface of the fixing block 38 contacts the inner wall of the storage groove 41 and is compressed. The second spring 36 is stretched. When the fixing block 38 moves to the side of the placement groove 42, the fixing block 38 enters the placement groove 42 under the elastic force of the second spring 36, thus completing the installation. During use, the operator introduces water into the inlet pipe 2. After being filtered by the filter screen 14, the water enters the outlet pipe 4 from the funnel 3 and finally enters the tank 7. When replacing the filter screen 14, the operator starts the motor 11, the first threaded rod 9 rotates, and the slide plate 10 moves along the slide groove 8 until the filter screen 14 to be replaced moves to the side of the opening 15. At this time, another filter screen 14 moves below the inlet pipe 2, and filtration can begin. The operator pulls the pull plate 24, which causes the locking block 23 to leave the slot 19, compressing the first spring 22. At this time, the operator pulls the handle 17, and the door 16 rotates, allowing the operator to pull out the filter screen 14 and replace it with a new one. The door 16 returns to its original position, and the operator releases the pull plate 24. The elastic force of the first spring 22 pushes the locking block 23 into the slot 19, thus fixing the door 16. In this way, the filter screen can be replaced without stopping the machine, improving filtration efficiency. During disassembly, the worker presses down the pressure plate 39, and the moving plate 37 moves the fixing block 38. The fixing block 38 leaves the placement groove 42, and the connecting pipe 5 can be disassembled, which improves the disassembly efficiency.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
