[0055] The sensor 15 is electrically connected to the solenoid valve 38 and can sense the user's action or approach to automatically open and close the water flow.

[0056] You can switch between the following two water outlet modes during use:

[0057] 1. Induction water outlet mode: When the handle 17 is at the handle position 24, it is the induction water outlet mode, and the default state is the closed state. Turn on the water outlet: In the induction water outlet mode, when the sensor 15 detects the return signal, the sensor 15 transmits the information to the control module of the control box 16, and the control module controls the solenoid valve to open, that is, the faucet water is discharged. When the sensor 15 detects the return signal again, it transmits the information again to the control module, and the control module controls the solenoid valve to close, that is, the water outlet is closed; Water outlet temperature adjustment: Turn the handle 17 back and forth to adjust the water outlet temperature.

[0058] 2. Mechanically control water flow: operate the handle 17 of the faucet to make the handle 17 at the handle position 2 25 to start water flow, and turn the handle 17 back and forth to adjust the water temperature; turn the handle 17 to the handle position 1 24 to turn off the water flow.

[0059] 3. When the handle 17 is in the handle position 24, the first water outlet 3 of the valve core and the cold water inlet channel 1 and the hot water inlet channel 2 are connected, and water is connected to the position of the solenoid valve 38 of the control box 16 through the second water outlet pipe 21 of the faucet assembly 14. The solenoid valve 38 is closed by default, and the induction signal controls the opening or closing of the solenoid valve 38 to realize water outlet and water shut-off; when the handle 17 is in the handle position 24, it is in the non-water outlet state by default, and the user may directly operate the handle Handle 17, that is, move the handle 17 to the handle position two 25, at this time, the second water outlet channel of the valve core is connected, and the water in the second water outlet channel is directly connected to the control box 16 through the first water outlet pipe 20, but will not pass through the solenoid valve 38, and will be directly connected to the faucet spout 44 to realize water outlet. When the faucet spout 44 does not discharge water, the handle 17 must be located at the handle position one 24. At this time, the user can control the water outlet directly through induction control, or directly operate the handle 17 to control the water outlet, and only one operation is required.
