Description

Smart multifunctional faucet

The invention relates to an intelligent multifunctional faucet, in particular to a faucet control technology that can illuminate and reveal the position of the faucet by the human body's proximity trigger in a dim environment.

Press, most mechanically operated faucets are mostly equipped with a set of knobs, long handles or levers on their top positions. The clockwise or counterclockwise rotation or swing of the knobs, long handles or levers to drive the on-off valve to open and close the faucet. Water outlet and adjust the amount of water. When operating this type of mechanical faucet, the user must use his hand to twist the control knob, long handle or lever to open and close or adjust the amount of water. During specific operation and control, since the user's hand will contact the knob, long handle or lever, etc., especially if the mechanical faucet is set in a public place, it will cause bacterial contact infection and hygiene. And many other problems.

In order to improve this deficiency, those in the related technical field have already developed a non-contact inductive faucet. The faucet is provided with a set of infrared sensors and an electromagnetic control valve. The infrared sensor detects whether an object enters. Its sensing range, when the user's hand enters its sensing range, the electromagnetic control valve is driven to open and close the water outlet for the user to flush, wash or use for other purposes; however, this non- The water flow opening and closing mode and opening time of the contact sensor faucet have been set in advance, so that if the non-contact sensor faucet is used in general home use, the use mode will be monotonous and not suitable for general home use. Miscellaneous multiple usage modes. For example, if the user wants to use a water mode that requires a long time to turn on the faucet (such as washing vegetables, fruits, clothes, or tea cups), suppose the preset opening time of the inductive faucet is set to 6 seconds. The use mode must take more than 6 seconds to complete the above-mentioned items. It can be seen that the conventional non-contact sensor faucet does cause inconvenience and extreme confusion due to lack of flexibility.

In order to further improve the above-mentioned shortcomings, those in the related technical field have already developed a device such as Invention Publication No. 200708677 “Touch Water Supply Device”, Invention Publication No. 201233923 “Faucet Device with Touch and Display Function” and Invention Publication No. 201734348 "Pressure-sensitive touch electronic faucet" and other patents. Although these patents have many functions such as touch operation to open, close, adjust water output, and temperature adjustment, they still have the following defects:

1. These patents do not have the setting of auxiliary functions such as light source sensing and lighting, so they cannot automatically illuminate and display the location of the faucet body in a dim environment, thus causing inconvenience and difficulties in operating the faucet in a dim environment .

2. These patents do not have the function setting of the fault detection information display, so it is impossible to identify the water leakage caused by the failure of the faucet electromagnetic control valve or the broken pipe, which is more likely to cause unnecessary waste of water resources.

3. The patent does not have functions such as self-power generation and gesture operation to switch the water output mode, so in addition to relying on city power to supply power and increasing the cost burden, it is even more difficult to control the water output of the faucet with simple gesture operations.

After the control unit interprets and processes the output, the一 Control valve and Close the fourth control signal of the second control valve and the third control valve, or output a fifth control signal of opening the second control valve and closing the first control valve and the third control valve, so that the water pipe The water flow of the road enters the first flow channel or the second flow channel, and flows out of the water outlet with a small water flow; when the human body makes a second gesture action to the gesture sensing part and the electric power value is higher than the preset When the power value is reached, a second gesture sensing signal is generated in the gesture measurement module, and the control unit enters a non-charged mode. After being interpreted and processed by the control unit, it outputs an opening of the first control valve and the second control. The valve and the sixth control signal for closing the third control valve cause the water flow of the tap water pipeline to enter the first flow channel and the second flow channel at the same time, and flow out of the water outlet with a larger water flow. The intelligent multifunctional faucet according to claim 1, further comprising a touch-sensing module and a set of control valves provided on the water inlet pipe or the water outlet pipe; the touch-sensing module includes a touch on the surface of the faucet body A sensing part and a resonance type sensing circuit. When the human body touches the touch sensing part, a touch sensing signal is generated in the resonance type sensing circuit, and after being interpreted and processed by the control unit, a control valve is opened and closed to control the control valve. Control signal. The intelligent multifunctional faucet according to claim 2, wherein when the human body touches the touch sensing part with a small area, a small offset of the touch sensing signal is generated; when the human body touches the touch sensing part, the touch sensing part is relatively small. When the area is large, a large offset of the touch sensing signal is generated. When the period of the small offset of the touch sensing signal is between 400 and 700 microseconds (ms), the control unit outputs to open and close the control. The control signal of the valve; when the period of the small-offset touch sensing signal is greater than 1000 microseconds (ms), the control unit outputs the control signal to adjust the amount of water in the control valve; when the offset is large, the touch-sensing signal When generated, the control unit outputs the control signal including the basic water flow on time plus the increased water flow on time. The intelligent multifunctional faucet according to claim 1, further comprising a gesture sensing module and a set of control valves provided on the water inlet pipe or the water outlet pipe; the gesture sensing module includes a gesture on the surface of the faucet body A sensing unit, when the human body makes at least one gesture action on the gesture sensing unit, a gesture sensing signal is generated in the gesture sensing module, and after being interpreted by the control unit, a control signal is output to open and close the control. Valve control signal. The intelligent multifunctional faucet according to claim 3 or 4, further comprising a water flu detection module and a display module for sensing a water flu test signal by sensing a water flow state of the water inlet pipe; when the water flu When a measurement signal is generated, the control unit converts it into a flow rate value and compares it with a preset flow rate value. When the flow rate value is higher than the preset flow rate value and the control valve is closed, the control unit outputs A fault signal representing a failure of the control valve is transmitted to the display module, and then the display module displays corresponding fault information. The intelligent multifunctional faucet according to claim 1, wherein the power supply unit includes a solar cell for converting light energy into electrical energy, a maximum power conversion charging circuit, and a rechargeable battery pack; the maximum power conversion charging circuit The electric energy is processed in a maximum power tracking manner to charge the rechargeable battery pack.
