Abstract

The utility model relates to an environmental protection and energy conservation tap device, comprising a temperature signal acquisition circuit, a human body induction circuit and a CPU controller. Output signals of the temperature signal acquisition circuit are transmitted to an A\D switching circuit through an amplifying circuit; and the output signals of the A\D switching circuit and the human body induction circuit are transmitted to the CPU controller and then transmitted to a magnetic valve driving circuit and an illumination driving circuit through output connection of the CPU controller. When people approach the tap, the environmental protection and energy conservation tap device heats water automatically with a delay of some time, opens the magnetic valve for allowing people to wash hands, and allows the tap to turn off automatically after the people leave; and when people approach the tap in the night, the environmental protection and energy conservation tap device turns on the illumination light first and then turns on the tap, and, when the people leave, allows the illumination light to turn off automatically after a delay of some time. The environmental protection and energy conservation tap device is simple in structure and extremely easy to use and has the function of energy conservation and environmental protection.

Description

A kind of water tap environment protecting power economizer

Technical field

The utility model relates to a kind of water tap environment protecting power economizer.

Background technique

Existing temperature adjusting water tap generally all adopts the mechanical adjustment structure, so ubiquity poor reliability, the control of fragile, water temperature such as are difficult at shortcoming.And induction tap only agree have the water outlet of induction control switch, and function ratio is more single.

The model utility content

The water tap environment protecting power economizer that the purpose of this utility model is to provide a kind of simple in structure, good reliability, has induction human body and control water temperature.

The technological scheme that the utility model adopted is such: a kind of water tap environment protecting power economizer, comprise temperature signal collection circuit, body induction circuit and cpu controller, the output signal of described temperature signal collection circuit through amplification circuit be transferred to A the D change-over circuit, described A the output signal of D change-over circuit and body induction circuit send to cpu controller, connect driving circuit for electromagnetic valve and illumination driving circuit by cpu controller output.

Described temperature signal collection circuit adopts K type temperature transducer collecting temperature signal.

Described body induction circuit is made of influence electricity pole piece, technotron and NE555 time-base integrated circuit.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: when the people walked close to water tap, after automatic heating of the time-delay regular hour water temperature, opens solenoid valve was washed one's hands for people, and water tap is closed automatically when the people leaves; The people is arranged when the water tap at night, walk close to as the people, at first open lighting burner, open water tap then, close automatically after the people leaves back lighting lantern festival time-delay certain hour, the utility model is simple in structure, uses very conveniently, has the function of energy-conserving and environment-protective.

Embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, a kind of water tap environment protecting power economizer, comprise temperature signal collection circuit 1, body induction circuit 2 and cpu controller 3, the output signal of described temperature signal collection circuit 1 through amplification circuit 11 be transferred to A D change-over circuit 12, described A the output signal of D change-over circuit 12 and body induction circuit 2 send to cpu controller 3, connect driving circuit for electromagnetic valve 31 and illumination driving circuits 32 by cpu controller 3 outputs.Described temperature signal collection circuit 1 is by K type temperature transducer TK, resistance R 4, electric capacity 2C1, diode 2D1, resistance 2R1, resistance 2R4, Deng composition, when the water that is contacted as K type temperature transducer TK reaches certain temperature, the K type temperature transducer TK the other end produces the 3rd pin that small d. c. voltage signal is connected to operational amplifier IC6, after operational amplifier IC6 internal signal amplifies, be input to the 2nd pin of A/D change-over circuit IC5 again by the amplifying signal of its 6th pin output, by the 5th of A/D change-over circuit IC5,6, the 25th of 7 pin and single-chip microcomputer IC1,26,27 pin connect to form datel circuit.When the detected water temperature of K type temperature transducer TK during 30 ℃ of left and right sides, through resistance R 3 triode VT2 is ended by the 6th pin output low level of single-chip microcomputer IC1, relay J 1 discharges, and solenoid valve is not worked, the beginning constant temperature water supply.When the water temperature of K type temperature transducer TK collection reaches the high-temperature temperature value of single-chip microcomputer IC1 setting, the output signal of operational amplifier IC6 is after A/D change-over circuit IC5 data transfer, single-chip microcomputer IC1 is judged as the condition of high temperature through internal processes, export high level through resistance R 3 current limlitings by the 6th pin of single-chip microcomputer IC1, make triode VT2 conducting, relay J 1 adhesive, solenoid valve gets electric, turns off water discharge of water faucet.

Described body induction circuit 2 is by influence electricity pole piece N, technotron TN, NE555 time-base integrated circuit IC3 forms, influence electricity pole piece N output terminal connects technotron TN, be connected to the 4th pin and the 8th pin of NE555 time-base integrated circuit IC3 through resistance R 1 by the drain electrode of technotron TN, the source electrode of technotron TN is connected to the 1st pin and the 5th pin of NE555 time-base integrated circuit IC3 through adjustable resistance W, the 3rd pin output terminal by NE555 time-base integrated circuit IC3 is delivered to single-chip microcomputer IC1 through resistance R 2, as the people during near influence electricity pole piece N, the induced signal of human body can make the leakage of technotron TN, resistance value between the source electrode increases, the 2 pin current potentials of NE555 time-base integrated circuit IC3 are lower than 2V, overturn through NE555 time-base integrated circuit IC3 internal circuit, its the 3rd pin becomes high level by low level, this moment, the 38th pin of single-chip microcomputer IC1 was high level state, after single-chip microcomputer IC1 internal processes is judged, the high level of the 8th pin output of single-chip microcomputer IC1 is through resistance R 4 current limlitings, make triode VT1 conducting, the relay J adhesive, contactor KM gets electric, connects the lighting installation power supply automatically.When unmanned during near influence electricity pole piece N, leakage, the resistance between the source electrode of technotron TN are less, electric current is bigger, the 2nd pin current potential of NE555 time-base integrated circuit IC3 is higher than 2V, after single-chip microcomputer IC1 internal processes was judged, the low level of the 8th pin of single-chip microcomputer IC1 output was ended triode VT1, and relay J discharges, contactor KM also discharges, and turn-offs the lighting installation power supply.

When human body during near influence electricity pole piece N, send control signal output by single-chip microcomputer IC1, at first connect electric consumption on lighting equipment and the tap of fetching boiling water, and control water temperature, reach the purpose of the intelligent control of energy-saving and environmental protection.
