[0079] In the embodiment, the second connecting pipe 2111 can be inserted into the first diversion cavity 105, and the second connecting pipe 2111 is sealed and fixedly connected to the first annular partition 1111. That is, the first input port 201 is connected to the first diversion cavity 105, and then the first input port 201 is connected to the water inlet 101.

[0080] like Figure 2 As shown, in some embodiments, the circumference of the filter unit 20 may be spaced apart from the inner wall of the housing assembly 10, so as to form a third flow channel 104 surrounding the filter unit 20.

[0098] In use, after the filtered water enters the first accommodation chamber 3202 through the second output port 203 and the second input port 301 in sequence, the filtered water can rush to the position of the partition 321 under the action of water pressure, and can enter the second accommodation chamber 3203 through the second through hole 3211 to infiltrate and dissolve the functional medium. The dissolved functional medium can follow the water flow through the second through hole 3211 into the first accommodation chamber 3202, and mix with the filtered water in the first accommodation chamber 3202 to form functional water. Subsequently, the functional water can be discharged from the functional medium supply unit 30 through the first through hole 3201 and the third output port 302 in sequence. In this process, the functional medium located in the second accommodation chamber 3203 can move toward the direction close to the partition 321 under the action of gravity.

Correspondingly, at least part of the filtered water can enter the second accommodating chamber 3203 through the second through hole 3211, infiltrate and dissolve the functional medium. Subsequently, the water flow carrying the functional medium can enter the first accommodating chamber 3202 through the second through hole 3211 again, and mix with the filtered water in the first accommodating chamber 3202 to form functional water. The functional water can be delivered to the third flow channel 104 through the first through hole 3201 and the third output port 302 in sequence. Afterwards, the functional water can be delivered to the third flow guide cavity 107 through the third flow channel 104 and delivered to the faucet 70 through the second water outlet 103 .

[0102] Of course, in other embodiments, the first water outlet 102 and the second water outlet 103 can be respectively connected to a faucet 70. Accordingly, the multifunctional filter element can also output filtered water and functional water at the same time.
