Background technique
Sensing sanitary appliance is that a kind of induction zone detects and opens the sanitary equipment of closing water supply electromagnetic valve after water supply electromagnetic valve supplies the people to use, use automatically when sensing the user near sanitary equipment automatically, and sensing sanitary appliance health easy to use is used very universal.After sensing sanitary appliance is opened water supply electromagnetic valve; If power supply breaks off, sensing sanitary appliance just can not be closed water supply electromagnetic valve, the outflow that the tap water in the sensing sanitary appliance will not stop always more automatically; Just can stop the water outflow up to the people for closing watering, will cause the waste of water resources like this.Though there have been some to adopt the sensing sanitary appliance of Alternating Current Power Supply when grid cut-off, can close water supply electromagnetic valve automatically now; This sensing sanitary appliance is equipped with the power supply adaptor of an AC-DC conversion to supply power to sensing sanitary appliance, the chip of special detection voltage is installed, in the sensing sanitary appliance behind grid power blackout; When the output voltage of power supply adaptor is lower than the threshold voltage of voltage checking chip; Voltage checking chip can be exported a signal and give single chip machine controlling circuit, and single chip machine controlling circuit sends the Guan Shui instruction again, and the electric energy stored on the electric capacity that is equipped with in the ABAP Adapter of general structure can not drive again closes solenoid valve; In order to close water supply electromagnetic valve automatically; The electrochemical capacitor of big capacity, big volume need be set on power supply adaptor, and its cost is higher relatively, and the automatic pass water when adopting the power supply adaptor power supply also can only solve grid cut-off; When power supply adaptor self breaks down or power supply adaptor output terminal when fault such as broken string occurring, can not close water automatically; Also have a lot of sensing sanitary appliances directly to adopt the dc-battery power supply at present; Because of circuit structure and installing space restriction; In the existing dc-battery power supply circuits jumbo electrochemical capacitor is not set; When power supply circuits the power supply circuits output terminal occurs opening circuit particularly when fault such as broken string occurring, still can not close water automatically.
Summary of the invention
When providing a kind of power circuit broken string or outage, the object of the invention can close the sensing sanitary appliance of water supply electromagnetic valve automatically.
The present invention adopts following scheme to realize: the sensing sanitary appliance that closes water during the power circuit outage automatically comprises infrared acquisition circuit, single chip machine controlling circuit and driving circuit for electromagnetic valve; The signal input part of single chip machine controlling circuit connects the output terminal of infrared acquisition circuit; Single chip machine controlling circuit control connection driving circuit for electromagnetic valve; The single chip machine controlling circuit power input links to each other with the output terminal of mu balanced circuit; Be provided with the coupled isolating diode of negative pole before the input end of wherein said mu balanced circuit, the positive pole of isolating diode links to each other with power circuit output end is anodal, and the negative pole of isolating diode also connects the positive pole of driving circuit for electromagnetic valve power input and energy-storage capacitor; The power circuit positive pole also connects broken circuit detection circuit, and the broken circuit detection circuit output terminal links to each other with the detection input end of single chip machine controlling circuit; When the power circuit output end normal power supply, power circuit drives single chip machine controlling circuit and driving circuit for electromagnetic valve work and energy-storage capacitor is charged; After the power circuit outage or breaking off; Single chip machine controlling circuit detects input end does not have the voltage signal input; Electric energy stored remains in operation single chip machine controlling circuit to detect whether opened solenoid valve of driving circuit for electromagnetic valve in the energy-storage capacitor; If it is opened to detect solenoid valve, then single chip machine controlling circuit control electromagnetic valve drive circuit cuts out solenoid valve.
Said energy-storage capacitor employing capacity is the energy-storage capacitor of farad level.
The capacity of said energy-storage capacitor is 0.022F/6.3V.
Said isolating diode adopts fast recovery diode.
The invention has the beneficial effects as follows: adopt said structure; In sensing sanitary appliance, increasing jumbo energy-storage capacitor, isolating diode and the broken circuit detection circuit of a microminiature size; After the circuit before power circuit outage or the power circuit output end breaks off; Single chip machine controlling circuit can in time detect; And electric energy stored can make single chip machine controlling circuit control electromagnetic valve drive circuit close opened solenoid valve in the energy-storage capacitor, makes sensing sanitary appliance can in time stop to supply water, and can not cause the waste of water resources.The present invention is applicable to the sensing sanitary appliance that adopts the power supply adaptor power supply, also is applicable to adopt the battery-powered sensing sanitary appliance of direct current.
