Abstract
The utility model discloses a kind of water saving control circuit, it comprises infra-red sensor switch P1, process chip U1, current amplifier U2 and battery valve K1 and forms; When human body away from time infra-red sensor switch P1 transmit a signal to process chip U1, process chip U1 exports control signal, and control signal closes water valve through current amplifier U2 and battery valve K1.This water saving control circuit is provided with infrared inductor and program control chip, and the control chip opens solenoid valve conducting current when human body proximity, the time delay shut electromagnetic valve when personnel leave, reaches water-saving object.
Description
Technical field
The utility model relates to electronic technology field, is specially a kind of water saving control circuit.
Background technique
Traditional water tap is is artificially opened and closed by manual handle, and structure is simple, economic and practical, has continued to use for a long time; But at day by day precious present of water resources, usually see the water tap of water that trickles lavishly in public places, deliberately perhaps artificial factor is all causing the waste of water resources every day unintentionally.
Model utility content
The purpose of this utility model is: provide the Electric water-saving control circuit that a kind of water faucet place installs.
In order to achieve the above object, the technological scheme adopted is:
A kind of water saving control circuit, it comprises infra-red sensor switch P1, process chip U1, current amplifier U2 and battery valve K1 and forms; When human body away from time infra-red sensor switch P1 transmit a signal to process chip U1, process chip U1 exports control signal, and control signal closes water valve through current amplifier U2 and battery valve K1.
The P26 end of described outside line induction switch P1 output terminal connection handling chip U1, the P27 end of process chip U1 connects the IN1 end of current amplifier U2, and the OUT1 end of current amplifier U2 connects battery valve K1; Described process chip U1 model is STC89C51, and described current amplifier U2 model is ULN2003A.
The beneficial effect of employing technique scheme is: this water saving control circuit is provided with infrared inductor and program control chip, the control chip opens solenoid valve conducting current when human body proximity, the time delay shut electromagnetic valve when personnel leave, reaches water-saving object.
Accompanying drawing explanation
Fig. 1 is the principle schematic of a kind of control circuit of economizing on water of the utility model.
Embodiment
The utility model is set forth further below in conjunction with specific embodiment or accompanying drawing, but not as the restriction foundation of protection domain; Any improvement project in the utility model right, all should be considered as protection domain of the present utility model.
As Fig. 1, a kind of water saving control circuit, it comprises infra-red sensor switch P1, process chip U1, current amplifier U2 and battery valve K1 and forms; When human body away from time infra-red sensor switch P1 transmit a signal to process chip U1, process chip U1 exports control signal, and control signal closes water valve through current amplifier U2 and battery valve K1.
The P26 end of described outside line induction switch P1 output terminal connection handling chip U1, the P27 end of process chip U1 connects the IN1 end of current amplifier U2, and the OUT1 end of current amplifier U2 connects battery valve K1; Described process chip U1 model is STC89C51, and described current amplifier U2 model is ULN2003A.
Place's external voltage type infrared inductor of P1 in figure, P3 connects dynamoelectric water valve, and P4 is communication interface, and X1X2 is clock circuit.
