1. A multi-control automatic faucet, comprising a faucet body, a manual valve core, a solenoid valve core, a water flow sensor, a main sensor switch, and a controller;
the faucet body including a main outlet water channel and a water control seat therein, the water control seat having a first outlet water channel and a second outlet water channel to communicate with the main outlet water channel;
the manual valve core being installed to the faucet body, the manual valve core having an outlet communicating with the first outlet water channel;
the solenoid valve core being installed in the faucet body, the solenoid valve core being configured to open and close the second outlet water channel;
the water flow sensor being installed in the faucet body, the water flow sensor being configured to detect whether water flows through the first outlet water channel;
the main sensor switch being installed to the faucet body, the main sensor switch being configured to sense a manual operation to control an action of the solenoid valve core;
the controller being electrically connected to the solenoid valve core, the water flow sensor and the main sensor switch;
wherein when the water flow sensor detects that there is no water flowing through the first outlet water channel, the controller controls the solenoid valve core to open the second outlet water channel according to a signal of the main sensor switch; when the water flow sensor detects that there is water flowing through the first outlet water channel, the controller controls the main sensor switch to be inactive and the solenoid valve core to close the second outlet water channel; wherein the manual valve core is a single-handle dual-control mixed water valve core, the single-handle dual-control mixed water valve core is located at an upper end of the water control seat;
the water control seat includes a first inlet water channel and a second inlet water channel each having upper and lower openings, the single-handle dual-control mixed water valve core has a first inlet and a second inlet to communicate with the upper openings of the first inlet water channel and the second inlet water channel, respectively; the water control seat further has a mixed water outlet communicating with the first outlet water channel, the mixed water outlet has an opening facing upwards, and the outlet of the single-handle dual-control mixed water valve core is in communication with the mixed water outlet;
wherein the second outlet water channel of the water control seat includes a water chamber and a sensor controlled water channel, the water chamber communicates with the sensor controlled water channel through a water-passing opening;
a valve head of the solenoid valve core is inserted into the water chamber and movably blocks the water-passing opening; and
wherein the water control seat further has a first inlet water passage communicating with the water chamber and the first inlet water channel and a second inlet water passage communicating with the water chamber and the second inlet water channel.
