[0031] Please refer to Figures 1 to 6 , a filter element, comprising:

[0032] A filter element cylinder 1 for accommodating the filter element;

[0033] A filter element joint, which is an integrally formed structure or a detachable connection with the filter element cylinder 1. The filter element joint includes an end cover assembly and a connecting pipe 4. The connecting pipe 4 is in internal communication with the filter element cylinder 1. After the liquid passes through the filter element for filtration, it is output by the connecting pipe 4. The end cover assembly includes an upper end cover 5 and a lower end cover 6 connected to each other. A snap structure for clamping with the mounting base 2 is provided on the side surface of the upper end cover 5, and the top surface of the upper end cover 5 is higher than the top surface of the snap structure.

[0034] In the filter element provided by the present application, the filter element connector is snap-fitted onto the mounting base 2 through a snap structure to achieve the assembly of the filter element cylinder 1 and the mounting base 2. The top surface of the upper end cap 5 is higher than the top surface of the snap structure, and there is a height difference between the upper end cap 5 and the snap structure. After snap-fitting, there is a certain gap between the upper end cap 5 and the mounting base 2 due to the height difference. In the state of high pressure or water hammer effect, the gap forms a yielding space, improving the assembly performance between the filter element cylinder 1 and the mounting base 2, enhancing the sealing and water hammer resistance, and effectively strengthening the anti-retreat structure function of the filter element.

[0035] In this embodiment, please refer to Figure 3 , the snap structure has a head 7 and a tail 8. The head 7 is farther from the filter element cylinder 1 than the tail 8. A stepped structure is formed between the head 7 and the top surface of the upper end cap 5. The tail 8 is flush with the top surface of the lower end cap 6. Specifically, the distance between the top surface of the upper end cap 5 and the top surface of the lower end cap 6 is H1, and the distance from the head 7 to the top surface of the lower end cap 6 is H2. H1 is greater than H2, and the difference between H1 and H2 forms a gap. The difference is preferably 0.01 mm - 1.5 mm.

[0036] In the above embodiment, both the upper end cap 5 and the lower end cap 6 are columnar structures. At least two snap structures are provided, and the snap structures are symmetrically arranged along the side surface of the upper end cap 5. A first limiting strip 9 for assembly limiting is arranged between the snap structures. In this embodiment, the snap structure is a symmetrically arranged rotary snap. When installing the filter element cylinder 1, rotate the filter element cylinder 1 to snap the snap structure onto the mounting base 2.

[0037] Specifically, the edge of the top surface of the upper end cap 5 is a chamfered corner or an inclined structure. An installation portion matching with the upper end cap 5 is arranged on the mounting base 2. Through the chamfered corner or inclined structure of the edge of the top surface of the upper end cap 5, it is convenient for the assembly of the upper end cap 5 and the installation portion.

[0038] In this embodiment, the end cap assembly and the connecting pipe 4 are integrally formed structures, enhancing the sealing performance between the end cap assembly and the connecting pipe 4.

[0039] In another embodiment, the present application further provides a water purification device, including: the filter element as above.

[0040] In some embodiments, the water purification device further includes: a support plate 15; a mounting base 2 connected to the support plate 15; the filter element is snap-fitted onto the mounting base 2, and multiple filter elements are arranged in a linear arrangement on the support plate 15. Specifically, a pipeline 16 is arranged on the support plate 15. One end of the pipeline 16 is connected to the mounting base 2 and communicates with the pipe body 13 in the mounting base 2, and the other end is connected to the support plate 15. Liquid enters the filter element cylinder 1 from the pipe body 13 and the connecting pipe 4, and after being filtered by the filter element, the filtered liquid is output from the connecting pipe 4 and the pipe body 13.

[0041] In the above embodiment, a pipe body 13 is provided on the mounting base 2. The pipe body 13 is communicated with the connecting pipe 4. A second limiting strip 14 for assembly limiting is arranged along the circumferential direction of the outer wall of the pipe body 13, and a third limiting strip 3 for assembly limiting is arranged along the circumferential direction of the inner wall of the mounting base. After the liquid is filtered by the filter element in the filter element cylinder 1, it successively passes through the connecting pipe 4 and the pipe body 13, and then the filtered liquid is output to the pipeline 16.

[0042] In this embodiment, a buckle structure 12 is arranged along the inner wall of the mounting base 2. The buckle structure 12 is matched with the snap structure. There is a recessed portion 10 between the head 7 and the tail 8 of the snap structure. The buckle structure 12 has a protruding portion 11. When the snap structure is assembled with the buckle structure 12, the recessed portion 10 is matched with the protruding portion 11 to connect the filter element joint with the mounting base 2. Through the cooperation of the recessed portion 10 and the protruding portion 11, when the snap structure and the buckle structure 12 are assembled in place, the user can perceive that the filter element is assembled in place, reminding the user that the assembly is completed. At the same time, it can enhance the stability of the filter element and prevent the filter element cylinder 1 from rotating and moving under the impact of water, resulting in water leakage.

[0043] In the above embodiment, the head 7 of the snap structure is an acute-angle structure. The head 7 extends into the buckle structure 12 until the recessed portion 10 is matched with the protruding portion 11. Through the angle setting of the head 7 of the snap structure, it is convenient to rotate the snap structure for assembly.

[0044] In summary, in the filter element provided in this application, the filter element joint is clamped on the mounting base 2 through the snap structure, realizing the assembly of the filter element cylinder 1 and the mounting base 2. The top surface of the upper end cover 5 is higher than the top surface of the snap structure. There is a height difference between the upper end cover 5 and the snap structure. After clamping, there is a certain gap between the upper end cover 5 and the mounting base 2 affected by the height difference. In the state of high pressure or water hammer effect, the gap forms a yielding space, improving the assembly performance between the filter element cylinder 1 and the mounting base 2, enhancing the sealing and water hammer resistance, and effectively enhancing the anti-retreat structure function of the filter element.

[0045] The above embodiments are only used to exemplarily illustrate the principles and effects of this application, rather than to limit this application. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in this application should still be covered by the claims of this application.
