[0047] The filter element assembly 3 includes a filter element unit 120 and a conductor 7 connected to each other. The conductor 7 and the connector 6 cooperate. One end of the conductor 7 is connected to the first gap 8, and the other end of the conductor 7 is connected to the filter element unit 120. There is a second gap 9 between the conductor 7 and the filter element unit 120. One end of the second gap 9 is connected to the filter element unit 120, and the other end of the second gap 9 is connected to the outlet 12.
[0048] Specifically, when the filter element assembly 3 is installed on the filter device, water flows into the valve body 1 from the inlet 11, and sequentially passes through the first gap 8, the conductor 7, the filter element unit 120, and the second gap 9, and flows out of the valve body 1 from the outlet 12, completing the filtration of the water; when the filter element assembly 3 is removed from the filter device, the push rod 41 is no longer limited by the filter element unit 120, the elastic element 5 extends, driving the push rod 41 to move away from the inlet 11 until the step portion 42 of the push rod 41 contacts the connecting body 6, so that the inlet 11 and the first gap 8 are no longer connected, and at the same time the push rod 41... 1. Move the connecting body 6 away from the inlet 11 until the connecting body 6 and the step part 2 come into contact, so that the gap 9 and the outlet 12 are not connected, and the inlet 11 and the outlet 12 are directly connected. At this time, water flows into the valve body 1 from the inlet 11 and flows out of the valve body 1 directly from the outlet 12.

[0067] Specifically, the connector 114 is used to connect the filter element unit 120 and the valve body 1. In order to increase the sealing between the connector 114 and the filter element unit 120, a sealing ring 118 made of silicone rubber, fluororubber, etc. can be set at the connection between the two.
[0068] Furthermore, it also includes a second sealing ring 115, which is fitted inside the valve body 1 and outside the connecting body 114.
