Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Embodiment
As shown in Figure 1, first the input end plug on laptop electric power adapter circuit is inserted on 220V power supply, output terminal inserts on notebook computer, button press switch AN1,3,4 ends of the U circuit on laptop electric power adapter circuit obtain electric work, 3,4 ends of U circuit export 19V DC voltage provides voltage to notebook computer, gives the charging of the battery in notebook computer simultaneously, makes notebook computer start work.The DC voltage of 3 ends outputs of U circuit is after the first resistance R1 step-down simultaneously, after voltage stabilizing diode VD1 voltage stabilizing, export 12V voltage charge to the first electric capacity C1 through the 3rd resistance R3, when the first electric capacity C1 is charged, make the base voltage of the first triode Q1 lower than emitter voltage through the 4th resistance R4, first triode Q1 conducting, collector exports high level and makes the second triode Q2 conducting through the 5th resistance R5, the 6th resistance R6 dividing potential drop, second triode Q2 conducting makes relay J 1 adhesive, switch J1-1 closes, and 1 end of U circuit is kept and 220V power on state.But after pushbutton switch AN1 disconnects, after first electric capacity C1 is filled electricity, the base voltage of the first triode Q1 is higher than emitter voltage, first triode Q1 ends, the collector of the first triode is without high level output, but the output terminal 4 end negative pole of U circuit is connected with the 3rd diode D3, 3rd diode D3 the 7th resistance R7 in parallel, when after computer normal boot-strap, 3rd diode D3 two ends, 7th resistance R7 two ends will produce the voltage of 0.5-0.7V, make the 3rd triode Q3 conducting, after 3rd triode Q3 conducting, collector output low level makes the 4th triode Q4 conducting, the emitter of the 4th triode Q4 is connected to U circuit output end 3 through the 4th diode D4 and rectifies on voltage, now, the collector of the 4th triode Q4 exports high level through the 8th resistance R8, 5th diode D5 connects the collector of the first triode Q1, the collector of the first triode Q1 is made to keep exporting high level, the second triode Q2 is made to keep conducting, relay J 1 keeps adhesive, switch J1-1 remains closed, U circuit maintenance work.
When after notebook electricity normal shutdown, as battery underfill electricity in notebook computer, power supply adaptor also will give battery charging in notebook computer, 3rd diode D3, the 7th resistance R7 two ends still can produce the voltage of 0.5-0.7V, make the 3rd triode Q3, the 4th triode Q4 maintenance conducting, second triode Q2 keeps conducting, and relay J 1 keeps attracting state, U circuit maintenance work.After battery is filled electricity; the positive electrode current of the 3rd diode D3 is very little; certain pressure drop can be produced at the 7th resistance R7 both ends; 3rd diode D3 is equivalent to by the 7th resistance R7 short circuit; 3rd diode D3 two ends can not produce the voltage of about about 0.5, and the 3rd triode Q3, the 4th triode Q4 and the second triode Q2 all end, relay J 1 not adhesive; U down circuitry, thus reach using electricity wisely and protection computer battery.
Wherein the second electric capacity C2 is delay capacitor, after the first triode Q1 or the 4th triode Q4 ends, second electric capacity C2 will be discharged to ground by the second triode Q2 base stage and emitter, make the second triode Q2 keep adhesive a period of time, reach the power supply that time delay a period of time disconnects U circuit.After switch J1-1 disconnects, after U circuit output end Non voltage output, the first electric capacity C1 will be discharged to ground by the first diode D1, the second resistance R2, and after making next button press switch AN1, the first electric capacity C1 can momentary charge, make relay J 1 reliably adhesive.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
