Brief description of the drawings
Fig. 1 is the circuit diagram of low-power consumption timing electronic switch.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearlyChu, intactly description, obviously, described embodiment is only the utility model part embodiment, instead of wholeEmbodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making under creative work prerequisiteThe every other embodiment obtaining, belongs to the scope that the utility model is protected.
Refer to Fig. 1, a kind of low-power consumption timing electronic switch, comprise potentiometer RP1, relay J, triode V1 and byKey K, a stiff end of described potentiometer RP1 connects sliding end, the negative electrode of diode D1, the diode of potentiometer RP1One of contact J-1, capacitor C 2, socket A and the NAND gate U1 of the negative electrode of D3, button K, relay J, relay JInput, another stiff end of potentiometer RP1 connects the anode of diode D4, and the negative electrode of diode D4 connects relayThe not moved end 1 of the contact J-2 of J, the not moved end 2 of the contact J-2 of relay J connects capacitor C 1, capacitor C 2, diodeThe emitter stage of the anode of D2 and triode V1, the anodic bonding relay J of diode D1 and the colelctor electrode of triode V1,The moved end of the contact J-2 of relay J connects another input of NAND gate U1 and the other end of capacitor C 1, NAND gate U1Output contact resistance R2, the base stage of the other end connecting triode V1 of resistance R 2, the other end of button K1 connects and continuesThe other end of the contact J-1 of electrical equipment J and 220V alternating current, the anodic bonding resistance R 1 of diode D3, diode D2'sNegative electrode and capacitor C 3, the other end of resistance R 1 connects capacitor C 3, the other end of resistance R 1 connect capacitor C 3 the other end,The other end of the other end of socket A and 220V alternating current.
Diode D4 is light emitting diode.
Operation principle of the present utility model is: D2, the D3 in circuit and the voltage stabilizing of C2, C3 composition capacitance decompression halfwave rectifierCircuit. At ordinary times, because the contact J 1 of button K and relay J is in open mode, whole circuit does not consume electric energy.Socket A also exports without 220V alternating current. The plug of controlled household electrical appliance is inserted in socket A. If electrical work, as long asClick button switch K, the just external power transmission of socket A. When this is because presses K, rectification circuit starts working, C2 twoEnd is just exported about 12V stable DC electricity for NAND gate U1 and transistor circuit. Due to an input of NAND gate U1By changeover contact ground connection, its output output high level, so V1 conducting, relay J obtains electric adhesive, changeover contactJ1 swings to upper end, and power supply charges to capacitor C 1 by RP1. Because charging needs certain hour, therefore the output of U1 keepsLow level, V1 continues to keep conducting state. The closed self-locking of another contact of relay J-1, after button K unclamps, timing is openedClose the work of still switching on, therefore the external power transmission of socket A makes to insert superincumbent electrical work. Along with the row that do not go on that charges, C1 two ends electricityPress the rising that do not continue, in the time reaching setting value, two inputs are high level, and output is low level, so triode V1Cut-off, relay J dead electricity discharges, and J-1 opens, and socket A just stops external power transmission. J-2 swings to and holds simultaneously, and C1 is logicalCross J1 electric discharge, for timing next time is prepared. Because J-1 opens, just there is not quiescent dissipation in whole time switch. RegularlyThe length of time can regulate by potentiometer RP1.
