Experimental results show that: it can reach purpose of design.

In order in conjunction with the embodiments the utility model to be done detailed description below, show as follows employed accompanying drawing number of present specification and title brief introduction:

Fig. 1: sound, light control circuit schematic diagram;

Fig. 2: the partial sectional view of the housing of interior dress sound, photocontrol printed circuit board (PCB) and electromagnetic valve coil.

Embodiment: ask for an interview Fig. 1-2, wherein, human body sensing probe M is that area is at (100-400) mm ²Between, the copper sheet of thickness between (0.2-1) mm, in this example, area is 15 * 15mm ², thickness is 0.5mm.In Fig. 1,5G7556 is the double trigger circuit chip, and pin 1-7 wherein and pin 14 used chip 5G7555 replace and available another chip of pin 7-14 5G7555 replacement.Behind the step-down filter circuit that resistance R 9, capacitor C 5 constitute, form dc source Vc again after exchanging the full-wave rectifying circuit that 220 volts of power supplys constitute via diode D1-D4, directly to

14,10 power supplies of chip 5G 7556; In FET 3DJ6 power supply, it also charges to capacitor C 3 by resistance R 10.By day, when the people walks close to the about 1.0-1.5 rice of human body sensing probe M, because of human body sensing, the DS utmost point moment shutoff of FET 3DJ6, the pin 12 of chip 5G7556 is by high potential step-down current potential, pin 11 then uprises current potential by electronegative potential, trigger IGCT BCR1 conducting, give the coil electricity of plastomer electromagnetic valve DF-15, valve open externally supplies water. and charging when capacitor C 3 simultaneously makes pin 13, when the current potential of pin 8 reaches 2/3Vc and people and leaves inductive probe M, chip 5G7556 turns back again, pin 11 becomes electronegative potential again, makes IGCT BCR1 blocking-up, the coil losing electricity of plastomer electromagnetic valve DF-15, valve-off, externally cut off the water supply. if when giving capacitor C 3 chargings, there is the people to come again or the people does not walk always then that pin 11 continues to keep high potential, externally supplies water.Stopping time through human body sensing probe M but not only as the people, though the unexpected step-down of S point current potential, but capacitor C 4 is still kept high potential in moment, chip 5G7556 does not overturn, have only as capacitor C 4 chip 5G7556 when resistance R 7, R6 discharge and current potential are lower than 1/3Vc and just overturn, valve can not opened water supply when therefore, the people was through human body sensing probe M.Power supply Vc powers to pin 2 via the resistor voltage divider circuit that resistance R 1, R2 are in series simultaneously, and pin 2 is connected to Electret condenser microphone HTD over the ground.Power supply Vc charges to capacitor C 1 through resistance R 3 again simultaneously, and capacitor C 1 its other end of ground connection links to each other with pin 1, pin 6.At night, when the people walks close to Water supply switch valve, Electret condenser microphone HTD makes the current potential of pin 2 by high step-down suddenly, chip 5G7556 upset, the current potential of pin 3 is uprised by low, makes IGCT BCR2 conducting, light the decent resistance R 3 of incandescent lamp L. power supply Vc this moment to capacitor C 1 charging, (can design on request its time delay), when the current potential of pin 6 reached 2/3Vc, chip 5G7556 turned back again, the current potential that makes pin 3 is by high step-down, IGCT BCR2 blocking-up, incandescent lamp L goes out. by day, because light resistor RS's is low resistive, make pin 4 be close to ground connection, even thereby because noise makes Electret condenser microphone HTD action, but chip 5G7556 can not overturn, thereby incandescent lamp L does not work.

On the acousto-optic control printed circuit board (PCB) 1 of Fig. 2, its T11, T12 end extremely links to each other with T1, the T2 of IGCT BCR1 respectively; Its T21, T22 end extremely links to each other with T1, the T2 of IGCT BCR2 respectively; N1, N2 end links to each other with electromagnetic valve coil; H1, H2 end links to each other with incandescent lamp L two ends; A, O end links to each other for 220 volts with interchange. and this circuit board 1 is connected with housing 2 usefulness screws.

Owing to adopt plastomer electromagnetic valve DF-15, not only reduced cost but also more met government's explicit order in the regulation of forbidding in interior decoration, using metallic conduit at the beginning of calendar year 2001.

This shows that this intelligent water saving machine structure tube list had not only been economized on water but also power saving, cost is also low.
