The key point of the present invention is that, as shown in FIGS. 1 and 2, the position of the intelligent control apparatus 4 changes from the water inlet end of the faucet body 1 to the water outlet end of the faucet body 1. The intelligent control apparatus 4 is electrically connected to the electric control valve box 5, and is used to control the faucet to discharge water and stop discharging water. The intelligent control apparatus 4 includes a photoelectric induction apparatus 7 and a drawable induction apparatus 9, wherein the photoelectric induction apparatus 7 and the drawable induction apparatus 9 are both electrically connected to the electric control valve box 5; that is, the photoelectric induction apparatus 7 can be triggered by waving a hand, so as to control the faucet to discharge water and stop discharging water; the drawable induction apparatus 9 can also be triggered to control the spout to discharge water and stop discharging water; the two apparatuses can be used separately to control the on-off of the waterway of the faucet. The specific structure is as follows:

As shown in FIGS. 1 and 5, the photoelectric induction apparatus 7 is an infrared induction switch which controls the on-off of the waterway of the faucet by means of an infrared reflection principle. The infrared induction switch is disposed in the faucet body 1, and an infrared induction region 8 is disposed on an outer side wall of the faucet body 1 at a position corresponding to the infrared induction switch. When a user puts a hand in the infrared induction region 8 outside the faucet body 1, an infrared ray emitted by an infrared emitting diode is reflected by the hand to an infrared receiving diode; a signal processed by a microcomputer in an integrated circuit is transmitted to an electromagnetic pulse valve; after the electromagnetic valve receives the signal, the electromagnetic valve opens a valve core according to a specified instruction, so as to control the spout to discharge water; when the hand leaves an infrared induction range and the electromagnetic valve does not receive the signal, the valve core of the electromagnetic valve resets by means of an internal spring, so as to control the faucet to stop discharging water.

In the present invention, the faucet body 1 is in an inverted U shape, and the infrared induction switch is located on an inner side of an inverted U-shaped faucet body opening. In the present invention, the photoelectric induction apparatus 7 is disposed at one end of the faucet body 1 adjacent to the spout 2, and the corresponding infrared induction region 8 is located on an inner side of an inverted U-shaped faucet body 1 opening, so as to effectively solve the problem of triggering by mistake the photoelectric induction apparatus 7. In an existing faucet, the photoelectric induction apparatus 7 for inducting a human body is disposed on a side wall of the faucet body 1 at a position in parallel with or close to a handle switch 12; the position of the induction region thereof is low, and is extremely adjacent to a mounting table of the faucet; when the handle switch 12 on one side of the faucet body 1 needs to be turned on manually, a human hand or an object passing through the induction region can easily trigger by mistake the photoelectric induction apparatus 7, causing sudden water discharge. Therefore, the use of the faucet is extremely inconvenient, thus having poor use experience.

The drawable induction apparatus 9 is disposed at one end of the faucet body 1 adjacent to the spout 2, and is used to control the drawing of a faucet switch in cooperation with the spout 2. As shown in FIGS. 1 and 5, the spout 2 is drawn out or resets to trigger the drawable induction apparatus 9; the drawable induction apparatus 9 transmits a draw-out signal or a reset signal to the electric control valve box 5; and the electric control valve box 5 controls the spout to discharge water or stop discharging water.

The drawing hose 3 and the spout 2 can also be connected by means of a connector made from other materials, as long as the connector can cooperate with the spout 2 to trigger the drawable induction apparatus 9.

In an initial state, as shown in FIGS. 4 and 5, a contact 11 of the mechanical ejector pin switch 10 is in contact with the metal connector 6; when the faucet is required to discharge water, the spout 2 is drawn out; the spout 2 drives the metal connector 6 and the drawing hose 3 to extend out of the faucet body 1; in this case, the contact 11 of the mechanical ejector pin switch 10 is separated from the metal connector 6, triggers the mechanical ejector pin switch 10, and transmits a signal to the electric control valve box 5; the electric control valve box 5 controls the faucet to open the waterway; when the faucet is required to be turned off to stop discharging water, the spout 2 is released from the hand and resets; the drawing hose 3 and the metal connector 6 retract into the faucet body 1 and resets; in this case, the metal connector 6 is in contact with the contact 11 of the mechanical ejector pin switch 10; the mechanical ejector pin switch 10 is triggered again; the electric control valve box 5 controls the faucet to close the waterway, such that the faucet stops discharging water.

In the present invention, the drawing induction position changes from the water inlet end of the faucet to the water outlet end of the faucet; when the spout 2 is drawn out, the drawable induction apparatus 9 is triggered not by means of the water inlet end of the farther drawing hose 3, but is directly triggered by means of the metal connector 6 between the water outlet end of the drawing hose 3 and the spout 2; in this way, the present invention not only reduces the response time and distance, but also overcomes the influence of the material of the drawing hose 3, enabling the response of the drawable induction apparatus to be quick, direct and precise.
