Accompanying drawing explanation
Fig. 1 is the circuit diagram of Multifunctional charger baby control circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of Multifunctional charger baby control circuit, including diode D1, audion V1, resistance R3 with continue
The emitter stage of electrical equipment J, described audion V1 connects the base stage of power supply VCC, audion V1 and connects resistance R1, resistance R1's
The colelctor electrode of other end connecting triode V2, the emitter stage of audion V2 connects resistance R4, resistance R6, diode D3
Negative electrode, the negative electrode of diode D4, the emitter stage of audion V3, the emitter stage of audion V4, the negative pole of accumulator E and
The base stage of load A, audion V2 connects resistance R2 and the colelctor electrode of audion V3, and the colelctor electrode of audion V1 connects electricity
The other end of resistance R2 and the anode of diode D1, the negative electrode of diode D1 connects resistance R3, resistance R5, diode D2
Negative electrode, relay K, the positive pole of accumulator E and relay K contact K-1, resistance R3 the other end connect resistance R4
The other end and the base stage of audion V3, the other end of resistance R5 connects the anode of diode D4, the anode of diode D2
The other end of connection resistance R6 and the base stage of audion V4, the other end of the collector connection relay K of audion V4,
The other end of resistance R7 connects the anode of diode D3.
Relay J is normally opened contact relay.Diode D3 and diode D4 is light emitting diode.
Operation principle of the present utility model is: audion V2, V3, resistance R3 and resistance R4 composition charging in circuit are automatically
Control circuit, when just starting to charge up, accumulator E both end voltage is relatively low, and audion V3 is not turned on, and audion V2 turns on,
Therefore audion V1 constant conduction work, and light emitting diode D4 is lighted as relay indicating light, along with the carrying out of charging,
Voltage after resistance R3 and resistance R4 dividing potential drop is sufficient so that audion V3 conducting, and therefore the base stage of audion V2 is drawn
Low, audion V2 ends so that audion V1 disconnects, thus disconnects charging voltage, prevents overcharge, two in circuit
Pole pipe D2, audion V4, resistance R6 and relay K composition under-voltage protecting circuit, when the voltage in accumulator E is normal,
It is enough to puncture relay K by the dividing potential drop of diode D2 and resistance R6, therefore the K-1 adhesive of its contact, and load A obtains electric,
And light emitting diode D3 lights as relay indicating light.Along with the carrying out of electric discharge, the voltage of accumulator E constantly reduces,
When drop to be not enough to maintain audion V4 conducting time, audion V4 disconnect, relay K dead electricity, its contact K-1 disconnect,
Effectively protection accumulator is from under-voltage damage.
