As shown in FIG. 1 and FIG. 4 and FIG. 8 , by the faucet composed of the above components, when the user's hand approaches the sensors 70, the electromagnetic valve 60 can be controlled to open, and the The electromagnetic coil 61 generates a magnetic field line by a current, the shaft 62 is magnetically attracted, and the shaft 62 is separated from the pressure release hole 67. At this time, the water pressure in the cold water passage 21 and the hot water passage 22 passes through the punching holes 68. The pressure of the punching hole 68 of the diaphragm 64 is smaller than the pressure relief hole 67, so that the water in the flat pressure chamber 66 is pressurized and is lost in the pressure relief hole 67, so the diaphragm 64 is deformed by the water pressure in the cold water passage 21 and the hot water passage 22, so that the diaphragm 64 is removed from the introduction end 261 (see FIG. 9), the spring 65 is compressed and contains a potential release force. And achieve the purpose of water.

Moreover, the operator operates the first operating handle 32 of the water temperature control unit 30 to adjust the amount of cold water and the amount of hot water passing through the flow control hole 23, and the water temperature can be adjusted according to the use requirement.

Conversely, when the user's hand is away from the sensors 70, the solenoid valve 60 can be controlled to generate a closing action. The shaft 62 is deactivated by the electromagnetic coil 61 to cause the shaft 62 to be closed again. The pressure relief hole 67, and the diaphragm 64 is subjected to the elastic force of the spring 65, so that the diaphragm 64 can close the lead-in end 261 of the lead-out passage 26 to achieve the purpose of stopping water.

When the inductors 70 are damaged, or the power of the battery pack 90 is exhausted, the operator can turn on the manual control unit 40, and allow the water in the cold water passage 21 and the hot water passage 22 to be merged to the bypass passage. The lead-in section 241 of the hole 24 flows through the lead-out section 242 and the connecting passage 27, and finally flows out of the outlet passage 26 and the outlet pipe group 80 to achieve manual water discharge.

Therefore, the faucet of the present invention can sense the water in the normal state and control the water, and when the sensors 70 are damaged, or the power of the battery pack 90 is exhausted, the water can be manually controlled, so the use is equivalent. Convenience.

The valve seat 20 is provided with a cold water passage 21 having a straight hole shape, a hot water passage 22, a flow control hole 23, a bypass through hole 24, a discharge passage 26 and a connecting passage 27, and the flow passage inside the valve seat 20 is simple in design. It can be made by injection molding and it is quite easy to manufacture. The valve housing 20, the electromagnetic valve 60, the inductor 70, and the battery pack 90 are additionally disposed inside the outer casing, and are connected to the water outlet assembly 80 to provide better positioning of the faucet assembly.

In summary, the new manual and automatic faucet can indeed solve the lack of the existing automatic faucet, and can achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
