But the present invention is not limited thereto, providing people with water flows of different temperatures can be directly connected to cold water pipes or hot water pipes. If mixed water is used, the water supply unit includes a cold water pipe 16, a hot water pipe 17 and a mixed water inlet pipe 14, the cold water pipe 16, the hot water pipe 17 and the mixed water inlet pipe 14, and the mixed water inlet pipe 15 is connected to the valve Core 3, the spool 3 controls the water in and out of the water pipe.

Take the vibration sensor as an example to illustrate the working principle of this embodiment below:

As shown in Figure 2 and Figure 5, the handle 2 is lifted up relative to the main body of the faucet 1, the water flows through the water supply port 106 of the water supply unit, the main control valve core 3 enters the mixed water inlet pipe 14, and enters the first three-way joint 7. Water outlet 71 is divided. Firstly, water flows through the main water inlet 71 of the first three-way joint 7, and the water flow is divided into a first split flow and a second split flow. In the first branch flow, the water flows from the first branch water outlet 72 of the first three-way joint 7, flows through the first connecting pipe 9, and enters the first branch water inlet 82 of the second three-way joint 8, so that the water flows through the first branch water inlet 82 of the second three-way joint 8. The first diversion flows to the water outlet 107 of the faucet body 2 through the mixed water outlet pipe 15; in the second diversion waterway, as the handle 2 drives the magnet 4 away from the electromagnetic induction element 13, the magnetic field around the electromagnetic induction element 13 weakens, and a The signal is sent to the power controller 11, the electromagnetic valve 6 is opened, and the vibration sensor 12 is started to work, so the water flows through the second connecting pipe 10, through the electromagnetic valve 6, and through the second diversion water inlet 83 of the second three-way joint 8, and finally It flows to the mixed water outlet pipe 15 and the outlet channel 106 of the faucet main body 2. At this time, the water flowing out of the faucet main body is a large flow.

If you tap the faucet body 2 lightly at this time, as shown in Figure 2 and Figure 6, the vibration sensor 12 detects a mechanical vibration signal, and a signal will be fed back to the controller 11, and the control box 11 will send a pulse signal to the solenoid valve 6 and Turn it off. Therefore, the second diverging waterway cannot discharge water, and only waterway 1 can discharge water. At this time, a small flow of water comes out. As shown in Figure 5, tap the main body 2 of the faucet again, a reverse pulse will be sent, the solenoid valve 6 will be opened, and the second diversion waterway will be connected again, at this time, the main body 2 of the faucet will flow out a large flow of water. Tapping the main body 2 of the faucet in this way can realize the adjustment of the flow rate of the outlet water and realize the effect of saving water.

When the handle 7 is reset and closed relative to the main body 2 of the faucet, the valve core will close the water supply port 106 of the water supply unit, and the main body 1 of the faucet can no longer discharge water. The magnet 4 is close to the electromagnetic induction element 13, and at the same time the magnetic field around the electromagnetic induction element 15 becomes stronger, and sends a signal to the control box 11, and the shock sensor 12 stops working. Tap the faucet body 1, the solenoid valve 6 does not work, and at the same time, the water flow is closed under the control of the main control valve core 3. Safe and reliable like this, prevent the waste of water, electricity.

Similarly, for sound-activated water-saving faucets, it is only necessary to design the vibration sensor to automatically sense the sound, and the controller will respond to the signal accordingly to control the solenoid valve, so as to realize the opening and closing of the waterway and realize water saving. the goal of.

The foregoing are only specific embodiments of the present invention, and the design concept of the present invention is not limited thereto. Any insubstantial changes made to the present invention by utilizing this conception all fall within the scope of protection of the present invention.
