A mounting hole is opened through the inner side of the fixing seat 10. An internal thread 11 is opened on the inner side of the mounting hole. A limiting ring 12 is fixedly connected to the inner side of the mounting hole. A second limiting frame 13 is fixedly connected to the inner side of the filter bucket 1. A filter element 14 is slidably inserted into the inner side of the second limiting frame 13. The connecting mechanism includes a first U-shaped frame 5, a threaded rod 6, a second U-shaped frame 7, and a nut 8. A sealing gasket is provided at the connection between the bucket cover 3 and the filter bucket 1. A first U-shaped frame 9 is welded and fixed to the outer side of the bucket cover 3. The first U-shaped frame 5 has a connecting shaft rotatably connected to its inner side, and a threaded rod 6 is welded and fixed to its outer side. One end of the threaded rod 6 is threadedly connected to a nut 8. The second U-shaped frame 7 is welded and fixed to the outer side of the filter tank 1. Drinking water enters through the first inlet valve 4, is filtered by the filter element 14, and the filtered water is discharged from the through hole of the fixed seat 10 to the first outlet valve 2, thus completing the filtration. The second inlet valve 16 and the second outlet valve 17 are in the closed state. When installing the filter element 14, it is only necessary to insert the filter element 14 through the second limiting frame 13 and screw it into the fixed seat 10. The threaded connection allows one end of the filter element 14 to fit against the top of the limiting ring 12, thus fixing the filter element 14 in place. The second limiting bracket 13 prevents the filter element 14 from shifting. Then, the bucket cover 3 is connected to the filter bucket 1, the threaded rod 6 is placed in the groove of the second U-shaped bracket 7, and the nut 8 is tightened to fix the bucket cover 3 in place. At this time, the bottom of the first limiting bracket 9 at the bottom of the bucket cover 3 abuts against the other end of the filter element 14, limiting the filter element 14 and preventing it from loosening after installation, thus achieving a better fixing effect and facilitating the disassembly or replacement of the filter element 14.

[0020] Furthermore, the outer wall of the filter element 14 is in contact with the inner wall of the second limiting frame 13, and one end of the filter element 14 is threadedly connected to the fixing seat 10 through the internal thread 11.
