Referring to fig. 7, under this structure, two paths of water from the dual water outlet valve core 5 can flow to the water outlet hole 24 of the valve seat 2 through the switching of the communicating member 12, so that only one water outlet pipe 6 connected with the valve seat 2 is needed, that is, the sensing faucet can realize two different water outlet modes only by one water outlet pipe 6, the structure cost is lower, and the number of accessories is less. The above-mentioned dual-outlet valve core 5 refers to a valve core capable of outputting two waterways in two different directions, such as some induction taps, having two water outlet modes of inducing water (solid arrow in fig. 5) and manually operating water outlet (open arrow in fig. 5), and the corresponding valve core has two water outlet waterways, the water outlet waterways are communicated to the water outlet hole 31 of the first communicating member, the solenoid valve 4 is used for realizing on-off control, the water outlet waterways of the manual operating water outlet are communicated to the water outlet hole 33 of the third communicating member, and the dual-outlet valve core 5 itself is used for realizing on-off control.
