The communication port of the sub-port 5 is inserted into the communication port of the female port 6, and a sealing ring 503 is disposed therebetween, and specifically, the sealing ring 503 may be clamped into the annular groove 504 on the outer side of the communication port of the sub-port 5. For example, the filter base 1 is provided with female connectors 6 at both ends thereof, the connector 3 is provided at an end thereof, and the communicating member 4 is provided with male connectors 5 at both ends thereof. Then, two communication interfaces on the female interface 6 are respectively the interfaces of the raw water channel 101 and the filtered water channel 102, while the raw water channel 101 is respectively the raw water inlet port 105 and the raw water outlet port 106 in the female interface 6 at the two ends of the filter base 1, and the filtered water channel 102 is respectively the filtered water inlet port 107 and the filtered water outlet port 108 in the female interface 6 at the two ends of the filter base 1. And two of the sub-ports 5 of the connector 3 are the block port 302 and the connection port 303, respectively, and two of the terminal ports 5 of the communication module 4 are the passage ports corresponding to the two communication passages 401, respectively.

Furthermore, in order to facilitate the filter 2 to be mounted on the filter base 1, it is preferable that the filter base 1 further includes a filtered water outlet pipe 109 and a filtered water inlet pipe 110, the filtered water outlet pipe 109 is sleeved on and coaxially disposed between the filtered water inlet pipes 110 to realize butt joint with a water filter, wherein the raw water channel 101 and the filtered water channel 102 are arranged in parallel along the radial direction of the filtered water outlet pipe 109, a portion of the raw water channel 101 passing through a cavity between the filtered water outlet pipe and the filtered water inlet pipe 110 is provided with an opening correspondingly communicated with each other, and a portion of the filtered water channel 102 passing through an inner cavity of the filtered water inlet pipe 110 is provided with an opening correspondingly communicated with each other; an outer port of the cavity between filtered water outlet pipe 109 and filtered water inlet pipe 110 is filtered water outlet 103, and an outer port of filtered water inlet pipe 110 is filtered water inlet 104. Furthermore, for the convenience of installation, an installation pipe may be sleeved outside the filtered water outlet pipe 109, wherein the installation pipe and the filtered water pipe are coaxially arranged.

Further, it is preferable here that of the two sides of the filter base 1 facing away: one side of the water outlet 103 and the water inlet 104 is provided with a raw water port 111 communicated with the raw water channel 101 and the other side is provided with a filtered water port 112 communicated with the filtered water channel 102; the raw water port 111 and the filtered water port 112 are both provided with sealing plugs 113. Generally, the filtered water outlet 103 and the filtered water inlet 104 are both located at the lower side of the filter base 1, the raw water port 111 and the filtered water port 112 are both located at the upper side of the filter base 1, and the two female ports 6 on the filter base 1 are respectively disposed at two sides of the filter base 1 away from each other in the horizontal direction. The raw water interface 111 and the filtered water interface 112 are sealed and blocked by the sealing plug 113, so that when external use is required, the sealing plug 113 can be pulled out, and other pipelines can be butted. In order to achieve a better sealing effect, it is preferable that an upper cover 114 is provided on a side having the raw water connection port 111 and the filtered water connection port 112, so that the side surface is flat.
