In addition, in order to facilitate processing and reduce manufacturing costs, the elastic plate is integrated with the casing 100 .

In some other embodiments, in order to further limit the end of the water treatment filter element 240 in contact with the supporting part 120, the two sides of the supporting part 120 are also provided with limiting parts 123, and the filter element is located between the two limiting parts 123 between.

Specifically, the limiting parts on both sides of the support part 120 form a limiting space, which can limit the position where the water treatment filter element 240 contacts with the supporting part 120 to the end in the limiting space, thereby improving installation reliability.

In some embodiments, at least one second mounting seat 104 may be provided on the casing 100 along the length direction of the filter element, and a recess is formed on the second mounting seat 104, and the water treatment filter element 240 is located in the recess. .

Specifically, after the two ends of the water treatment filter element 240 are respectively fixed and installed through the external interface 2103 and the support part 120, the water treatment filter element 240 is configured with at least one second mounting seat 104 in its length direction, and the second mounting seat 104 forms The recessed part can further position and support the central area of the water treatment filter element 240, which is more conducive to improving the installation reliability.
