Abstract
The utility model relates to an infrared auto-induction faucet. The infrared auto-induction faucet comprises an oscillator circuit, an infrared modulator circuit, a decoding circuit, an electromagnetic valve driving circuit and a voice alarm circuit, wherein an output signal of the oscillator circuit is transmitted to the infrared modulator circuit, and an output signal of the infrared modulator circuit is sent to the electromagnetic valve driving circuit and the voice alarm circuit under the control of the decoding circuit. According to the infrared auto-induction faucet, an infrared light emitting diode and an infrared receiving tube are assembled together to form an integrated infrared induction component. The infrared auto-induction faucet has the advantages of being capable of achieving a voice prompt function, flexible, reliable, strong in the antijamming capability, and capable of working under the strong light condition.
Description
Technical field
The utility model relates to a kind of inductive faucet, particularly be a kind of infrared auto-induction tap.
Background technique
Water is indispensable in our daily life, but is extremely valuable, particularly extremely lacks nowadays in water resources, and how using water wisely is the problem that everyone faces.Existing water apparatus function is single, slow movement, poor reliability, can not satisfy actual objective demand.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of infrared auto-induction tap is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the infrared auto-induction tap, comprise pierce circuit, infrared modulated circuit, decoding circuit, driving circuit for electromagnetic valve and voice alarm circuit, the output signal of described pierce circuit transfers to the infrared modulated circuit, and the output signal of described infrared modulated circuit is sent to driving circuit for electromagnetic valve and voice alarm circuit through decoding circuit control.
Preferably, described pierce circuit is made of resistance R 1, adjustable potentiometer W1, the capacitor C 1 of 555 time base circuit IC1 and connection thereof.
Preferably, described infrared modulated circuit is made of infrarede emitting diode D1 and corresponding infrared receiving tube BG thereof, and the output terminal of described infrared receiving tube BG is connected with amplifier IC2.
Preferably, described decoding circuit adopts LM567 decoder IC3.
Preferably, described voice alarm circuit is made of the triode Q1, the speech chip IC5 that connect successively, LM386 Audio Frequency Amplifier IC6 and news Chinese percussion instrument Y.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: the utility model is assembled together infrarede emitting diode and infrared receiving tube, becoming one infrared induction parts, has voice reminder, sensitive reliable simultaneously, advantages such as antijamming capability is strong can be worked under high light.
Description of drawings
Fig. 1 is block diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, infrared auto-induction tap of the present utility model, comprise pierce circuit 1, infrared modulated circuit 2, decoding circuit 3, driving circuit for electromagnetic valve 31 and voice alarm circuit 32, the output signal of described pierce circuit 1 transfers to infrared modulated circuit 2, and the output signal of described infrared modulated circuit 2 is sent to driving circuit for electromagnetic valve 31 and voice alarm circuit 32 through decoding circuit 3 controls.
Described pierce circuit 1 is by the resistance R 1 of 555 time base circuit IC1 and connection thereof, adjustable potentiometer W1, capacitor C 1 constitutes, described infrared modulated circuit 2 is made of infrarede emitting diode D1 and corresponding infrared receiving tube BG thereof, the output terminal of described infrared receiving tube BG is connected with amplifier IC2, drive infrarede emitting diode D1 and send modulated infrared light, when the people washes one's hands or is filled with water near water tap, the infrared rays that is sent by infrarede emitting diode D1 is reflected a part by human body, BG receives by infrared receiving tube, and by after the amplifier IC2 amplification, be input to input end the 3rd pin of LM567 decoder IC3, after LM567 decoder IC3 knows decoding, make its 8th pin output low level, the relay J adhesive, normally opened contact JH connects power of electromagnetic valve, solenoid valve is opened, the water tap automatic streamline.Because the 8th pin output low level signal of LM567 decoder IC3; after diode D2 isolates output; speech chip IC5 obtains power supply voltage; the 2nd pin output voice audio signals of speech chip IC5; be coupled to the 3rd pin of LM386 Audio Frequency Amplifier IC6 through capacitor C 8; after internal audio frequency amplifies, send voice reminder through the 5th pin output capacitance C9 of LM386 Audio Frequency Amplifier IC6 coupling amplification promotion news Chinese percussion instrument Y again and " ask using water wisely, protection water resources ".Speech chip IC5 is the customized voice chip, and internal memory " is asked using water wisely, protection water resources ".
Behind human body leaving water tap, infrared receiving tube BG loses infrared signal, and circuit returns to wait state again, and LM567 decoder IC3 exports high level signal, and relay J is in not attracting state, and water tap is in off state.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
