[0029] Embodiment:

[0030] An ultrafiltration filter element that is convenient for disassembly and assembly, as Figures 1-3 shown, includes an outer cylinder 4. A partition 3 is arranged inside the outer cylinder 4. Above the partition 3 is a carbon fiber cotton filter element 2. Below the partition 3 is an ultrafiltration membrane 5. The top of the outer cylinder 4 is provided with a top cover 1, and the bottom of the outer cylinder 4 is provided with a bottom shell 6;

[0031] The outer cylinder 4 and the top cover 1 are connected by snap fit, and the outer cylinder 4 and the bottom shell 6 are connected by a rotary buckle.

[0032] In a possible implementation, the lower end of the top cover 1 is press-fitted into the upper end of the outer cylinder 4, and the upper cover 1 of the filter element and the outer cylinder 3 of the filter element are pressed and installed by interference fit, which is convenient for disassembly.

[0033] In a possible implementation, a number of buckles 41 are arranged in an annular array on the inner side of the lower end of the outer cylinder 4, and a number of clamping grooves 61 are opened on the outer side of the upper end of the bottom shell 6. The clamping grooves 61 adopt an L-shaped structure, including a through groove and a sliding groove. The buckle 41 passes through the through groove and slides in the sliding groove.

[0034] In a possible implementation, a stop rib 62 is provided at one end of the sliding groove away from the through groove. The outer cylinder 3 and the bottom shell of the filter element are fixed by the cooperation of the buckle and the clamping groove, and the stop rib is also provided on the bottom shell clamping groove. There will be an obvious sense of section when the outer cylinder is installed and disassembled to inform the user whether it has been tightened or loosened (generally, the structure of the ultrafiltration filter element has no outer cylinder, and the bottom shell directly grows taller to wrap the ultrafiltration membrane, and the ultrafiltration membrane cannot be disassembled and exposed).

[0035] In a possible implementation, a step 42 is provided inside the outer cylinder 4, a partition 3 is arranged on the step 42, and a number of outer cylinder ribs 43 are also provided on the inner side of the outer cylinder 4. A rib position and a step are arranged in the middle of the outer cylinder 3 to place the partition. An activated carbon fiber cotton filter element can be further placed on the partition to increase the filtering effect of the filter element.

[0036] In a possible implementation, the ultrafiltration membrane 5 is fixed to the top of the bottom shell 6.

[0037] By adopting the above technical solutions:

[0038] The outer cylinder and the upper cover can be conveniently disassembled, and the ultrafiltration membrane filaments can be exposed for cleaning, reused, or replaced; the activated carbon fiber filter element can also be conveniently replaced;

[0039] Each part is easy to disassemble for cleaning or recycling.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
