Description
Technical field
The invention belongs to Electric automatic control and water-saving technology field, is about a kind of hand touch water-saving tap.
Background technique
At present, main flow infrared ray control tap mainly contains two kinds:
1. shading type infrared rays auto-switch tap, when people stretches out one's hand washing, blocked by infrared beam, water tap is automatically opened and is discharged water; Wash Bi Renti when leaving, time delay discharges water and automatically closes afterwards for several seconds.
2. infrared ray control tap, the circuit of infrared ray control tap is divided into be sent out, receives two-part, and be placed in the both sides of water tap, when staff is close to water tap, the infrared rays that infrared transmitting tube sends reflexes to infrared receiving tube through staff, receiving tube is automatically converted to electrical signal after receiving the optical signal of reflection, amplifies further through subsequent conditioning circuit, controls electromagnetic water valve to fetch boiling water tap finally by drive circuit; When staff is away from water tap, receiving tube does not receive the optical signal of reflection, and drive circuit disconnects electromagnetic water valve power supply, and water tap is closed automatically.
Hand touch water-saving tap of the present invention looks for another way, and it all uses ordinary electronic components and parts to make, and it is simple, cheap, withstand voltage, easy to maintenance that it has structure; Have in use easy to operate, health, water tap beat open or close finish rapidly, power consumption is little, not by advantages such as various opto-magnetic signal interference, this water tap is adapted at the occasions such as hotel, office building, hospital, passenger station, airport, laboratory and uses, and its shortcoming is that water flow size can not control.
Below describe the guardian technique content that hand touch water-saving tap of the present invention is involved in implementation process in detail.
Summary of the invention
Goal of the invention and beneficial effect: hand touch water-saving tap of the present invention looks for another way, and it all uses ordinary electronic components and parts to make, and it is simple, cheap, withstand voltage, easy to maintenance that it has structure; Have in use easy to operate, health, water tap beat open or close finish rapidly, power consumption is little, not by advantages such as various opto-magnetic signal interference, this water tap is adapted at the occasions such as hotel, office building, hospital, passenger station, airport, laboratory and uses.
Circuit working principle: its core parts are one piece of extensive CMOS acoustic control intergrated circuit (SK-6), and it all can normally work under 3 ~ 8V low voltage.When connecting 7.5V DC electrical source, acoustic control IC 1 automatic clear, in the 8th pin output low level of acoustic control IC 1, NPN type triode VT1 ends, and electromagnetic water valve DCF coil does not work without electricity.When hand touch tinsel M time, acoustic control IC 1 is triggered upset, exports high level from the 8th pin of acoustic control IC 1, NPN type triode VT1 conducting, make the connection DC electrical source of electromagnetic water valve DCF, electromagnetic water valve DCF is opened, and tap water flows out from water tap; When point again touch tinsel M time, acoustic control IC 1 triggers upset again, and the 8th pin of acoustic control IC 1 recovers low potential, and NPN type triode VT1 ends, and cuts off the DC electrical source of electromagnetic water valve DCF, and water tap stops supplying water.
Technical characteristics: hand touch water-saving tap, it comprises 7.5V DC electrical source, touch signal and shaping amplification circuit, electromagnetic water valve drive circuit, it is characterized in that:
Touch signal and shaping amplification circuit: it is made up of touch electrode M, resistance R1, acoustic control IC 1, resistance R2, the model that acoustic control IC 1 is selected is SK-6,6th pin connection circuit positive pole VCC of acoustic control IC 1, acoustic control IC 1 the 5th pin meets touch electrode M, the two ends of the 2nd pin of acoustic control IC 1 and the 3rd pin difference connecting resistance R2, the 7th pin connection circuit ground GND of acoustic control IC 1;
Electromagnetic water valve drive circuit: it is made up of resistance R3, NPN type triode VT1, electromagnetic water valve DCF, switching diode D1,8th pin of acoustic control IC 1 connects the base stage of NPN type triode VT1 by resistance R3, the collector electrode of NPN type triode VT1 connects one end of electromagnetic water valve DCF coil and the positive pole of switching diode D1, the emitter connection circuit ground GND of the other end of electromagnetic water valve DCF coil and the negative pole connection circuit positive pole VCC of switching diode D1, NPN type triode VT1;
The positive pole connection circuit positive pole VCC of 7.5V DC electrical source, the negative pole connection circuit ground GND of 7.5V DC electrical source.
