The filter member 22 includes a filter portion 221 and a first connection portion 222 surrounding the outer circumference of the filter portion 221, the over-flow region 211 can expose the filter portion 221 of the filter member 22 so that water to be filtered flows to the filter portion 221 through the over-flow region 211, and the filter portion 221 can be used to filter the water flowing from the first filter housing 21 to the second filter housing 23.

That is, the water flowing back from the drinking water chamber 111 to the water storage chamber 112 can be achieved by the structure in which the overcurrent area 211 exposes the filter portion 221 of the filter member 22, reaches the filter portion 221 of the filter member 22 through the overcurrent area 211 of the first filter housing 21, and then is filtered by the filter portion 221 through the filter assembly 2.

Further, please refer to fig. 10 and fig. 11 in combination.

The first filter housing 21 is provided with a connecting groove 212, the notch of the connecting groove 212 faces the second filter housing 23, the first connecting portion 222 of the filter element 22 is inserted into the connecting groove 212, and the first connecting portion 222 is hermetically connected with the groove wall of the connecting groove 212. The design of the notch of the connection groove 212 towards the second filter housing 23 can avoid water accumulation at the connection of the filter element 22 and the first filter housing 21, further reduce the possibility of water backflow from the first filter housing 21 and the gap between the filter elements 22, further ensure that the filter assembly 2 realizes full interception and filtration, and improve the filtering effect of the filter assembly 2.

Please continue to refer to fig. 9 and 10. In an embodiment, the first connection portion 222 is embedded in a groove space surrounded by the first groove wall 2121, the second groove wall 2122, and the third groove wall 2123, and the first connection portion 222 is connected to at least one of the first groove wall 2121, the second groove wall 2122, and the third groove wall 2123 in a sealing manner.

That is, the first connection portion 222 of the filter member 22 is sealingly connected to at least one groove wall of the first filter housing 21. Therefore, the filtering member 22 is hermetically connected to the first filtering housing 21, so that the water to be filtered is difficult to flow out from the gap between the filtering member 22 and the first filtering housing 21, that is, the water is filtered by the filtering member 22 through the filtering member 22 as much as possible, thereby avoiding the occurrence of insufficient filtering, facilitating the filtering assembly 2 to realize full interception and filtering, and improving the filtering effect of the filtering assembly 2.

Alternatively, the first slot wall 2121 may be located on a side of the second slot wall 2122 away from the over-flow region 211.

Alternatively, the sealing member 24 may be a sealing ring or the like, and further, may be a silicone ring or the like. The silica gel ring has the characteristics of wide temperature application range, good sealing performance, good insulativity and the like, is not easy to be disturbed by the outside to cause quality change, and is a relatively ideal sealing material.

Wherein, when the sealing element 24 is a silicone ring, the sealing groove 2221 may be a semi-arc groove or the like. That is, the shape of the sealing groove 2221 should be adapted to the edge characteristics of the sealing element 24, so as to reduce the gap between the sealing groove 2221 and the sealing element 24 as much as possible, further improve the sealing effect of the filter assembly 2, and improve the filtering effect of the filter assembly 2.

Therefore, after the drinking water flows through the first filtering shell 21, the filtering member 22 can filter impurities in the water when passing through the filtering member 22, wherein the filtering member 22 is connected with the first filtering shell 21 in a sealing manner, so that the drinking water is difficult to flow out from a gap between the filtering member 22 and the first filtering shell 21, the drinking water is made to pass through the filtering member 22 and receive the filtering effect of the filtering member 22 as much as possible, thereby being beneficial to the realization of the filtering assembly 2 to realize the full interception and filtration, and improving the filtering effect of the filtering assembly 2.
