Abstract
The utility model provides an automatic control circuit that economizes on water of tap, infrared sensor P1 and pressure sensor P2's signal output part all is connected with the signal input part who handles chip U1, the signal output part who handles chip U1 is connected with switch tube MN1's grid, and switch tube MN1's source stage ground connection drains and is connected with solenoid valve P3's one end, solenoid valve P3's the other end and power end are connected, it has diode D1 still to establish ties between solenoid valve P3's the both ends. The utility model discloses a setting up pressure sensor, infrared sensor and processing chip, standing on being equipped with pressure sensor's mat when human, when the last infrared sensor of tap sensed the human body and exists, pressure sensor and infrared sensor's sensing signal transmitted respectively to handling the chip, handle the chip through switch tube control solenoid in order to switch on rivers, delay time when the human body leaves and close the solenoid valve, reach water -saving purpose.
Description
Technical field
The utility model relates to water tap automatic control technology field, is specifically related to a kind of water tap automatic 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 also 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 personal factor is all causing the waste of water resources every day unintentionally.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of water tap automatic water-saving control circuit, this water tap automatic water-saving control circuit is by arranging pressure transducer and infrared senor, and induction triggers water tap, solves conventional faucet and easily wastes water problem.
The utility model is achieved by the following technical programs.
A kind of water tap automatic water-saving control circuit that the utility model provides, comprises infrared senor P1, pressure transducer P2, solenoid valve P3, switching tube MN1, process chip U1; Described infrared senor P1 is all connected with the signal input part of process chip U1 with the signal output part of pressure transducer P2, the signal output part of described process chip U1 is connected with the grid of switching tube MN1, the source class ground connection of switching tube MN1, drain electrode is connected with one end of solenoid valve P3, and the other end of described solenoid valve P3 is connected with power end; Diode D1 is also in series with between the two ends of described solenoid valve P3.
The model of described process chip U1 is STC15F104W.
The input end of described infrared senor P1 is connected with the emitter of triode Q1, and the collector electrode of triode Q1 is unsettled, and base stage is connected with 7 pin of process chip U1 by resistance R.
The beneficial effects of the utility model are: by arranging pressure transducer, infrared senor and process chip, be equipped with on the mat of pressure transducer when human body stands in, when infrared senor on water tap senses that human body exists, the induced signal of pressure transducer and infrared senor transfers to process chip respectively, process chip passes through switching tube control solenoid valve with conducting current, the time delay shut electromagnetic valve when human body leaves, reaches water-saving object.
