[0034] The surface of the faucet 1 is also provided with a mounting seat 5. The shape of the mounting seat 5 is not specifically limited, as long as it is a part of the surface of the faucet 1. Specifically, in this embodiment, it is an end face of a truncated cone formed on the surface of the faucet 1. A first contact 6 is exposed on the mounting seat 5. The first contact 6 is electrically connected to the solenoid valve 4, specifically, it can be electrically connected through a wire, and the first contact 6 can be any existing conductive contact, including a connector-type contact structure;

[0035] A switch element 7 is provided on the control box 2, and the switch element 7 can be any existing device that can send a signal to control the solenoid valve 4 to open and close the valve. Setting the switch element 7 to control the solenoid valve 4 to open and close the valve is a conventional technical means in this field, and its principle will not be described in detail. The preferred embodiment is given in the following text; a mounting surface 8 is formed on the surface of the control box 2, and the mounting surface 8 and the mounting seat 5 can be magnetically attracted to each other, so that the mounting surface 8 can be detachably fixed on the mounting seat 5. Specifically, a magnet 24 is provided on the mounting surface 8, and the mounting seat 5 is made of a metal material that can be magnetically attracted by the magnet 24. Of course, the mounting surface 8 and the mounting seat 5 can also be detachably installed by other existing detachable mounting structures such as plug-in or card-connection. Magnetic attraction is only a preferred solution. A second contact 9 is exposed on the mounting surface 8. The structure of the second contact 9 is not limited, as long as it can match the first contact 6 so that the two can be connected and conducted. The second contact 9 is electrically connected to the switch element 7;

[0036] The second contact 9 and the first contact 6 are set in such a position that when the control box 2 is fixed to the mounting seat 5 through the mounting surface 8, the two can overlap and conduct, so as to electrically connect the switch element 7 to the solenoid valve 4, so that the switch element 7 can be used to control the opening and closing of the solenoid valve 4.

[0037] Specifically, a power supply is also provided, and the power supply is used to supply power to the switch element 7 and the solenoid valve 4; a programmable controller is also electrically connected between the first contact 6 and the solenoid valve 4, and / or between the second contact and the switch element 7, and the programmable controller is used to convert control signals between the switch element 7 and the solenoid valve 4, so that the signal sent by the switch element 7 can be used to control the solenoid valve 4 to switch the valve. Of course, the setting of the power supply and the programmable controller can be completed according to conventional technical means of those skilled in the art (the preferred embodiment can refer to Figure 7 shown).

[0038] In a preferred embodiment of the switch element 7, the switch element 7 includes an infrared sensing switch and / or a touch sensing switch and / or a mechanical switch. The infrared sensing switch is used to control the solenoid valve 4 to open when it senses that a human hand enters an area outside the control box 2; the touch sensing switch is used to control the solenoid valve 4 to switch between opening and closing when it senses that an area on the surface of the control box 2 is touched by a human hand; the mechanical switch has a movable switch key, which is used to control the solenoid valve 4 to open when the switch key is moved to a first position, and to control the solenoid valve 4 to close when it is moved to a second position. The infrared sensing switch, touch sensing switch and mechanical switch are all existing technologies in the field and will not be described in detail.

[0039] Preferably, the faucet 1 is also provided with a water flow monitoring sensor 13 on the water path between the solenoid valve 4 and the water outlet 3. The water flow monitoring sensor 13 can be any existing sensor that can be used to detect the physical or chemical state of water flow. The water flow monitoring sensor 13 is electrically connected to the first contact 6. The control box 2 is also provided with a display screen 14, which is electrically connected to the second contact 9, so that after the first contact 6 and the second contact 9 are connected, the display screen 14 can be used to display the monitoring information of the water flow monitoring sensor 13. Specifically in this embodiment, the water flow monitoring sensor 13 includes a water temperature sensor and / or a flow sensor and / or a TDS sensor. All of the above sensors are conventional sensors in this field. TDS is total dissolved solids. The TDS sensor can measure the content of inorganic and organic matter dissolved in water, and then be used to judge the water quality.

It can also be arranged that when the second contact 9 and the first contact 6 are turned on, the battery 18 supplies power to the solenoid valve 4, so that the battery box 2 can be removed at any time to replace the battery.

[0041] In order to avoid relative displacement between the control box 2 and the mounting seat 5 when the control box 2 is magnetically attracted to the mounting seat 5, resulting in misalignment of the first contact 6 and the second contact 9, it is preferred that the outer ring edge of the mounting seat 5 is concave to form a groove 19, and the outer ring edge of the mounting surface 8 is convex to form a convex edge 20, and the convex edge 20 matches the contour of the groove 19, so that when the control box 2 is fixed to the mounting seat 5 through the mounting surface 8, the convex edge 20 is embedded in the groove 19 for positioning; and the first contacts 6 are arranged in plurality at intervals, the number and position of the second contacts 9 correspond to the first contacts 6, and the first contacts 6 are recessed on the mounting seat 5, while the second contacts 9 are spring pins convexly provided on the mounting surface 9.

The faucet switch 25 is formed with a handle 26 outside the faucet 1 . The handle 26 is turned to mechanically open or block the connection between the solenoid valve 4 and the water outlet 3 .

[0043] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
