The holding portion 433 may be disposed protruding from a surface of the filter element pulling cover 43 on a side far away from the first filter cavity 3a, or may be disposed recessed from a surface of the filter element pulling cover 43 on a side near the first filter cavity 3a, or may be formed with a groove around the holding portion 433 so as to hold the holding portion 433.
In one embodiment, referring to fig. 3, the first filter assembly 4 includes a partition 435, the partition 435 partitions the first filter chamber 3a such that the pre-filter 41 and the post-filter 42 are disposed at opposite sides of the partition 435, respectively, and the pre-filter 41 and the post-filter 42 are connected to the partition 435, respectively.
In the present embodiment, when the first filter assembly 4 includes both the pre-filter cartridge 41 and the post-filter cartridge 42, the first filter assembly 4 includes the partition 435, wherein the partition 435 connects the pre-filter cartridge 41 and the post-filter cartridge 42, respectively, and the partition 435 is used to partition the first filter chamber 3a into a chamber for filtering the pre-filter cartridge 41 and a chamber for filtering the post-filter cartridge 42, so that the pre-filter cartridge 41 and the post-filter cartridge 42 will not interfere in the filtering process, to prevent raw water in the filter chamber of the pre-filter cartridge 41 from contaminating pure water in the filter chamber of the post-filter cartridge 42. The specific connection mode of the partition 435 and the pre-filter 41 and the post-filter 42 is gluing, so that the pre-filter 41 and the post-filter 42 can be kept in a certain form after being pressed by water, and the pre-filter 41 and the post-filter 42 are prevented from being impacted or deformed by water pressure. The separator 435 has a specific structure of a separator, and the outer circumference of the separator or the outer circumference near the separator extends toward opposite sides of the separator, respectively, so as to wrap part of the outer circumferences of the pre-filter 41 and the post-filter 42, thereby achieving a better supporting effect on the pre-filter 41 and the post-filter 42.
Further, in an embodiment, referring to fig. 4, a second sealing ring 62 is disposed between the partition 435 and the separator 3.
According to the above embodiment, it is considered that, in order to make the partition 435 better separate the filter chamber of the pre-filter 41 from the filter chamber of the post-filter 42, the second seal ring 62 is provided between the partition 435 and the cartridge 3, and the upper and lower sides of the partition 435 are sealed by the second seal ring 62. Specifically, a second accommodating groove 435a is provided on the outer periphery of the partition 435 to better limit the second sealing ring 62, so that a part of the second sealing ring 62 is accommodated in the second accommodating groove 435a, and another part of the second sealing ring 62 is exposed out of the notch of the second accommodating groove 435a and is in interference fit with the inner wall of the separator 3.
