When the water tap needs to output warm water, the first opening valve 2 is opened, and the first opening valve 2 is adjusted, so that cold water flows into the water mixing cavity 1d through the cold water inlet channel 11a and the first water through hole 171, hot water flows into the water mixing cavity 1d through the hot water inlet channel 11b and the second water through hole 172, the cold water and the hot water are mixed in the water mixing cavity 1d to form warm water, and the warm water flows out through the third water through hole 173, the last passage 1e, the first water outlet pipe 121 and the first water outlet 12 in sequence, specifically referring to the direction indicated by the hollow arrow shown in fig. 3 to 6.

When cold water needs to be filtered by the pre-consumer, the second open valve 3 is opened, and the cold water flows out through the cold water inlet channel 11a, the second open valve 3, the micro water flow power generation device 6 and the filter element in sequence, the third communication port 153, the last water outlet flow channel 1f and the second water outlet 13, and flows into the subsequent consumer, specifically referring to fig. 1, 8 and 9, wherein the flowing out cold water is filtered cold water.

When filtered hot water needs to be supplied to the pre-consumer, the second open valve 3 is opened, and the hot water flows out through the hot water inlet channel 11b, the second open valve 3, the micro water flow power generation device 6 and the filter element in sequence, and then flows into the subsequent consumer through the third communication port 153, the last water outlet flow channel 1f and the second water outlet 13, specifically referring to fig. 1, fig. 10 and fig. 9, wherein the flowing hot water is filtered hot water.
