Abstract
The utility model relates to the field of water-saving valves, in particular to a photoelectrical water-saving valve, which comprises an infrared transmitting circuit, an infrared receiving circuit, a single chip microcomputer circuit, an electromagnetic valve driving control circuit and a voice prompting circuit. Output signals of the infrared transmitting circuit are transmitted to the infrared receiving circuit, the output signals of the infrared receiving circuit are transmitted to the electromagnetic valve driving control circuit and the voice prompting circuit via the single chip microcomputer control circuit, when a person washes hands, the body of the person shades infrared opposite rays, water flows from an electromagnetic valve, energy-saving advertising messages are played, when the person leaves away from the water-saving valve, a faucet is closed automatically, so that waste of water resources is avoided, and the purpose of saving energy and protecting environments is achieved.
Description
Technical field
The utility model relates to the water-saving valve field, particularly be a kind of photoelectric type water-saving valve.
Background technique
Now owing to considering that social all our undertakings development should carry out vigorously advocating synthesis energy saving synchronously with environmental resource protection, synergy etc. lowers consumption; and the protection of water resources that is called Source of life is become increasingly important; people are in the protection water resources; except reducing the pollution and coyoting to water resources, scientific and reasonable water is also particularly important and urgent with raising comprehensive water-saving rate.
At present, tap water consumptions such as China's exhausting work and production and processing are growing on and on, and existing various water taps are more and more both at home and abroad, but mostly mainly adopt the body sense mode more, are easy to generate false triggering.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of photoelectric type water-saving valve is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of photoelectric type water-saving valve, comprise infrared emission circuit, infrared receiving circuit, single chip machine controlling circuit, solenoid Valve driving control circuit and voice warning circuit, the output signal of described infrared emission circuit is sent to infrared receiving circuit, and the output signal of infrared receiving circuit is delivered to solenoid Valve driving control circuit and voice warning circuit through single chip machine controlling circuit.
The multivibrator circuit output that described infrared emission circuit is made up of NE555 time base circuit and peripheral circuit thereof connects the gallium arsenide luminotron tube and constitutes.
Described infrared receiving circuit adopts the HG41 phototransistor to gather signal.
Described single chip machine controlling circuit adopts the 89C51 single-chip microcomputer as host CPU.
Described voice warning circuit is made of photoelectricity coupling module, speech chip, LM386 audio-frequency power amplifier and loudspeaker.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: when human body was washed one's hands, human body covered infrared to ray, solenoid valve is fetched boiling water, and plays energy-conservation advertising slogan, when human body leaves, water tap is closed automatically, avoids water resource waste, reaches the purpose of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is a frame assumption 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, a kind of photoelectric type water-saving valve of the present utility model, comprise infrared emission circuit 1, infrared receiving circuit 2, single chip machine controlling circuit 3, solenoid Valve driving control circuit 4 and voice warning circuit 5, the output signal of described infrared emission circuit 1 is sent to infrared receiving circuit 2, and the output signal of infrared receiving circuit 2 is delivered to solenoid Valve driving control circuit 4 and voice warning circuit 5 through single chip machine controlling circuit 3.
The multivibrator circuit output that described infrared emission circuit 1 is made up of NE555 time base circuit IC4 and peripheral circuit thereof connects gallium arsenide luminotron tube VD and constitutes, the frequency of this multivibrator circuit is about 2KHZ, described infrared receiving circuit 2 adopts HG41 phototransistor VT to gather signal, broken by sugarcane near the light beam between luminous VD of gallium arsenide and the HG41 phototransistor VT as human body, the output terminal utmost point of HG41 phototransistor VT is high value of resistance, the 3rd pin incoming level of 89C51 single-chip microcomputer IC1 is high level state, after the comprehensive judgement of single-chip microcomputer IC1 internal processes, the 2nd pin output high level signal by 89C51 single-chip microcomputer IC1 makes triode Q2 conducting through resistance R 6, therefore speech chip IC2 obtains power supply voltage, the 2nd pin output audio alert signal of speech chip IC2, be coupled to the 3rd pin of LM386 audio-frequency power amplifier IC3 through capacitor C 3, after its internal audio frequency amplifies, after capacitor C 4 couplings that the 5th pin output terminal of LM386 audio-frequency power amplifier IC3 connects are amplified, promote the voice suggestion that loudspeaker Y sends " everybody using water wisely " again; The 21st pin output high level signal of another route 89C51 single-chip microcomputer IC1 makes triode Q1 conducting through resistance R 5 current limlitings, makes relay J 1 adhesive, its contact J1-1 is by becoming normally closed point normal battle simultaneously, it is electric that solenoid valve is got, and the tap of fetching boiling water is for the guest provides water.
When human body leaves, light beam between luminous VD of gallium arsenide and the HG41 phototransistor VT is not broken by sugarcane, the output terminal of HG41 phototransistor VT is low resistance, the 3rd pin incoming level of 89C51 single-chip microcomputer IC1 is low level state, the 21st pin output low level signal by 89C51 single-chip microcomputer IC1, triode Q1 is ended, relay J 1 is discharged, its contact J1-1 becomes normal battle by normally closed point simultaneously, make the solenoid valve dead electricity, turn-off water tap, stop water outlet, avoid water resource waste, reach the purpose of energy-conserving and environment-protective.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
