Accompanying drawing explanation
Fig. 1 is the circuit diagram of electronics water tap.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of electronics water tap, comprise optocoupler U1, resistance R1, battery pack E, electric capacity C1, diode D1, bidirectional triode thyristor VS and solenoid valve Y, battery pack E positive pole contact resistance R1, the resistance R1 the other end connects light emitting diode positive pole in optocoupler U1, in optocoupler U1, light emitting diode negative pole connects battery pack E negative pole by switch S, phototransistor collector electrode contact resistance R4 and resistance R5 respectively in optocoupler U1, the resistance R4 the other end connects electric capacity C1 and diode D1 negative pole respectively, diode D1 positive pole connects the T1 pole of 220V Ac one end and bidirectional triode thyristor VS respectively, the T2 pole connected electromagnetic valve of bidirectional triode thyristor VS, the G pole connecting luminous diode D2 positive pole of bidirectional triode thyristor VS, light emitting diode D2 negative pole contact resistance R3, resistance R3 the other end connecting triode VT1 collector electrode, triode VT1 base stage connects phototransistor VT1 emitter and resistance R2 in optocoupler U1 respectively, the resistance R2 the other end is connecting triode VT1 emitter respectively, the solenoid valve Y the other end, the resistance R5 the other end, the electric capacity C1 the other end and the 220V Ac the other end.
Battery pack E voltage is 3V.
Optocoupler U1 model is 4N25.
Working principle of the present utility model is: refer to Fig. 1, and S is foot-operated key switch, and 220V civil power, through diode D1 one way rectifier, exports the collector electrode of VDC to the inner phototransistor of U1 of about 10V after electric capacity C1 filtering, resistance R4, R5 dividing potential drop.
At ordinary times, S switch disconnects, and in U1 interior light emitting diodes, no current is not by luminous, and its inner phototransistor cut-off, transistor VT1 ends, and light emitting diode D2 is not luminous, and bidirectional triode thyristor VS blocks, and solenoid valve Y must not work by electricity.When using tap water, available foot-operated upper switch S, S closes, and have electric current to make it luminous by light emitting diode in U1, in it, phototransistor is by illumination conducting, and VT1 is conducting also, and state instruction is done in D2 luminescence, and VS connects 220V civil power, and Y obtains tele-release water.Complete with water, pin departs from switch S, and U1 quits work, and VT1 ends, and D2 extinguishes, and VS blocks, and Y dead electricity stops discharging water.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
