In this embodiment, the inductive switch 620 employs an infrared switch 621 and a proximity switch 622, and the infrared switch 621 and the proximity switch 622 are disposed on the faucet main body 600 at intervals; when the infrared switch 621 detects an external object (for example, a hand of a user), the controller 410 controls the temperature adjustment motor 310 to operate, so that the valve cartridge 200 is opened, and after the hand of the user is separated from the infrared switch 621, the controller 410 controls the valve cartridge 200 to be closed. After the hand of the user approaches the proximity switch 622, the controller 410 controls the temperature adjustment motor 310 to turn on the valve element 200 for a predetermined time and then turn off the valve element 200, and after the hand of the user approaches the proximity switch 622 again, the controller 410 controls the valve element 200 to turn off immediately, so as to meet the water requirements of different users.

When the valve core 200 is in a closed state, the cold water hole 221 and the hot water hole 222 are covered by the ceramic sheet 230, cold water enters the cold water hole 221 from the cold water runner 1211, hot water enters the hot water hole 222 from the hot water runner 1212, and the water outlet hole 212 is communicated with the water outlet passage 122;

when a user needs to use water, the user approaches the infrared switch 621 (taking the infrared switch 621 as an example) through a hand, after the infrared switch 621 detects the hand of the user, the controller 410 controls the temperature adjusting motor 310 to operate, that is, the output end of the temperature adjusting motor 310 drives the valve rod 240 and the ceramic tile 230 to integrally rotate, so that the first switching hole 231 is communicated with the cold water hole 221, the first switching hole 231 is communicated with the hot water hole 222, cold water in the cold water hole 221 and hot water in the hot water hole 222 both enter the water outlet hole 212 through the connecting cavity 241 and the notch 242, and then warm water mixed by the cold water and the hot water is discharged from the water outlet channel 122, so that the valve element 200 is opened;

when the user presses the temperature increase key 421, the controller 410 controls the temperature adjustment motor 310 to drive the valve rod 240 and the ceramic tile 230 to rotate by a predetermined angle, so that the communication area between the first switching hole 231 and the cold water hole 221 is reduced, and meanwhile, the communication area between the second switching hole 232 and the hot water hole 222 is increased, thereby increasing the outlet water temperature; when the user presses the temperature increasing key 421 for multiple times and continuously, the water outlet temperature is gradually increased along with the pressing times of the user, and when the pressing times of the temperature increasing key 421 reach the upper limit of the gear set by the controller 410, the movable ceramic piece 230 rotates to a state that the switching hole two 232 is completely communicated with the hot water hole 222, and at the moment, the communication area of the switching hole one 231 and the cold water hole 221 is not less than half of the full communication area of the switching hole one, so that the highest water outlet temperature is prevented from exceeding 49 ℃;

when a user presses the temperature reduction key 422, the controller 410 controls the temperature adjustment motor 310 to drive the valve rod 240 and the ceramic sheet 230 to rotate reversely by a predetermined angle, so that the communication area between the first switching hole 231 and the cold water hole 221 is increased, and the communication area between the second switching hole 232 and the hot water hole 222 is reduced, thereby realizing the reduction of the outlet water temperature; when the user presses the temperature reduction key 422 for multiple times and continuously, the water outlet temperature is gradually reduced along with the pressing times of the user, and when the pressing times of the temperature reduction key 422 reach the minimum gear set by the controller 410, the movable ceramic sheet 230 rotates to completely cover the hot water hole 222, and when the first switching hole 231 is communicated with the cold water hole 221, the cold water outlet of the water outlet channel 122 is realized;

after the hand of the user is out of the detection range of the infrared switch 621, the controller 410 sends a closing command to the temperature adjustment motor 310, and controls the temperature adjustment motor 310 to drive the valve rod 240 and the movable ceramic piece 230 to rotate reversely, so that the movable ceramic piece 230 covers all the cold water hole 221 and the hot water hole 222, and the valve core 200 is in a closed state at this time. If the controller 410 has executed the command to close the valve cartridge 200 and the temperature adjustment motor 310 can still rotate toward the closing direction of the valve cartridge 200, which indicates that the valve rod 240 is not completely reset, the controller 410 controls the temperature adjustment motor 310 to continue to rotate until the valve cartridge 200 is completely closed and the current of the temperature adjustment motor 310 is increased to the monitored value and then stopped, and the calibration of the output end of the temperature adjustment motor 310 is completed.

When a user presses the flow increasing key 423 during water use, the controller 410 controls the flow adjusting motor 500 to drive the adjusting sheet 1241 to rotate, so that the adjusting sheet 1241 reduces the blocking area of the water outlet passage 122, the water outlet flow of the water outlet passage 122 is increased, the user presses the flow increasing key 423 repeatedly and continuously, the water outlet flow can be increased gradually along with the pressing times of the user, when the pressing times of the flow increasing key 423 reach the maximum gear set by the controller 410, the adjusting sheet 1241 rotates to be parallel to the water flow moving direction in the water outlet passage 122, the area of the water outlet passage 122 through which water flows is the largest at the moment, the water outlet flow is also the largest, and the flow increasing key 423 is pressed again at the moment, so that the controller 410 does not act any more.

When a user presses the flow reducing key 424 in the water using process, the controller 410 controls the flow adjusting motor 500 to drive the adjusting piece 1241 to rotate reversely, so that the adjusting piece 1241 increases the blocking area of the water outlet passage 122, the water outlet flow of the water outlet passage 122 is reduced, the user presses the flow reducing key 424 for multiple times and continuously, the water outlet flow can be reduced gradually along with the pressing times of the user, when the pressing times of the flow reducing key 424 reach the minimum gear set by the controller 410, the adjusting piece 1241 rotates to a state perpendicular to the movement direction of the water flow in the water outlet passage 122, the area of the water flow passing through the water outlet passage 122 is minimum, the water outlet flow is also minimum, at this time, the flow reducing key 424 is pressed, and the controller 410 does not act any more.

In addition, during the water use process of the user, the external power supply supplying power to the controller 410 is unexpectedly powered off, and the power storage power supply 411 supplies power to the controller 410 in an emergency, so that the controller 410 can control the temperature adjustment motor 310 to close the valve cartridge 200.

If the water demand of the user is large, the valve core 200 can be opened through the proximity switch 622, and after a preset time (for example, 2 minutes) after the valve core 200 is opened, the controller 410 controls the valve core 200 to be closed again; if the valve cartridge 200 is in the open state and the user's hand approaches the proximity switch 622, the controller 410 immediately controls the temperature-adjusting motor 310 to turn off the valve cartridge 200.

The above description is intended to be illustrative of the present invention and not to limit the scope of the utility model, which is defined by the claims appended hereto.
