[0043] The device provided in this embodiment enables the top cover 3 to be installed and removed from the outer cylinder 1 quickly and effectively, thereby facilitating the cleaning of the interior of the outer cylinder 1 and the replacement of parts inside the outer cylinder 1 .

[0044] The use process of a precision filter provided by the utility model is as follows: when in use, first inject the water to be filtered into the outer cylinder 1 through the water inlet 4, the water entering the outer cylinder 1 is filtered by the filter element 8, and then discharged outward through the drain port 9 and the water outlet 5. When the filter element 8 needs to be replaced, first pull the connecting handle 24 so that the connecting handle 24 drives the connecting rod 22 to move in the direction away from the outer cylinder 1, and when the connecting rod 22 moves, it drives the plug-in plate 25 to move at the same time. When the plug-in plate 25 moves to disengage from the plug-in slot 26, the plug-in plate 25 cancels the limit on the connecting block 12, and then the top cover 3 can be pulled in the direction away from the outer cylinder 1 to separate the top cover 3 from the outer cylinder 1. At the same time, when the top cover 3 moves, it drives the filter element 8 to move at the same time. When the filter element 8 is completely moved out of the inner side of the outer cylinder 1, the filter element 8 can be taken out from the outer cylinder 1.

[0045] When the filter element 8 needs to be replaced, the filter element 8 is first moved in the direction close to the top cover 3. When the filter element 8 moves, the second conical block 16 is driven to move at the same time through the fixing column 14. When the second conical block 16 moves, it will squeeze the limiting block 21, so that the limiting block 21 moves in the direction close to the second spring 19. When the limiting block 21 moves to the point where the first conical block 15 is disengaged, the top end of the second conical block 16 is fitted with the lower end of the first conical block 15, and the limiting block 21 cancels the limit on the first conical block 15. Then the filter element 8 is moved in the direction away from the top cover 3, so that the filter element 8 drives the first conical block 15 and the second conical block 16 to move at the same time through the fixing column 14. At this time, because the second conical block 16 is fitted with the first conical block 15, the limiting block 21 cannot move to the first conical block 15 and the position between the second conical block 16, so that the fixing column 14 can be removed from the inside of the top cover 3, thereby completing the disassembly of the filter element 8, and then replacing a new filter element 8, moving the fixing column 14 to the connecting groove opened in the top cover 3, when the fixing column 14 drives the first conical block 15 to move, it will squeeze the limiting block 21 to move in the direction close to the second spring 19, when the first conical block 15 moves to the point where it no longer contacts the limiting block 21, the limiting block 21 is pushed in the direction close to the fixing column 14 under the elastic action of the second spring 19, because the second conical block 16 is limited by the first spring 17, there is a certain space between the second conical block 16 and the first conical block 15, so that the first conical block 15 can be limited by the limiting block 21, and the installation can be completed.
