Description
Technical field
The present invention relates to a kind of circuit, more particularly to a kind of power-saving circuit.
Background technology
With the progress of science and technology, possess the portable set of battery, electronic product to propagate its belief on a large scale at present, the life of people is more and more come into, use along with portable set, electronic product is more and more, and portable set, the problem of electronic product electricity use time length are increasingly protruded.
At present; the universal cognition of people is when portable set, electronic product are turned off when inapplicable; the consumption of electricity is reduced with this, however, being in security consideration; battery typically can all have the protection circuit of itself; such as mu balanced circuit, filter circuit, although the load circuit of outside batteries no longer consumes electricity after equipment is closed, but the protection circuit being connected with battery is still operated; there is electric quantity consumption, can so reduce the use time of TV.
The content of the invention
In consideration of it, being necessary to provide a kind of power-saving circuit, to solve portable set, electronic product when shutdown is not used, the kwh loss of battery is reduced.
A kind of power-saving circuit, the power-saving circuit includes power supply, power source protective module, switch module and load blocks, the power source protective module is connected to the positive pole of the power supply with the load blocks, the switch module includes first switch, triode, relay and first resistor, the load blocks are connected by the first switch with the positive pole of the power supply, the base stage of the triode is connected between the first switch and the load blocks by the first resistor, the relay includes battery core coil and second switch, the battery core coil is connected between the colelctor electrode of the positive pole of the power supply and the triode, the grounded emitter of the triode, the second switch is connected between the positive pole of the power source protective module and the power supply.
Further, the power supply is battery.
Further, the switch module also includes diode.
Further, the diode is in parallel with the relay.
Further, the switch module also includes second resistance, and an end of the second resistance is connected between the base stage of the triode and the first resistor, the other end ground connection of the second resistance.
Power-saving circuit of the invention; by setting triode, relay and the combination of switch; make after load blocks are stopped; current potential reduction, triode ON, adhesive switch makes battery protection module stop power supply after relay power; make portable set, electronic product after shut down; battery protection module is also disconnected with battery, reduces the power consumption of battery, improves the use time of battery.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction withAccompanying drawingAnd embodiment, it is bright to this point penalty to be further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Refer toFigure 1WithFigure 2, whereinFigure 1For the function of power-saving circuit of the invention is illustratedFigure,Figure 2It is the circuit of power-saving circuit of the inventionFigure.Power-saving circuit of the invention 100 includes power supply 10, power source protective module 20, switch module 30 and load blocks 40, and power source protective module 20 is connected to the positive pole of power supply 10 with load blocks 40, and power supply 10 is used to be powered to whole circuit 100.
Switch module 30 includes first switch 31,Triode 32,Relay 33,First resistor 34,Diode 35 and second resistance 36,Load blocks 40 are connected by first switch 31 with the positive pole of power supply 10,The base stage of triode 32 is connected between first switch 31 and load blocks 40 by first resistor 34,Relay 33 includes battery core coil 331 and second switch 332,Battery core coil 331 is connected between the colelctor electrode of the positive pole of power supply 10 and triode 32,The grounded emitter of triode 32,Second switch 332 is connected between the positive pole of power source protective module 20 and power supply 10,Diode 35 it is in parallel with relay 33,The negative electrode of diode 35 is connected to one end that battery core coil 331 is connected with power supply 10,The anode of diode 35 is connected to one end that battery core coil 331 is connected with the colelctor electrode of triode 32,One end of second resistance 36 is connected between the base stage of triode 32 and first resistor 34,The other end ground connection of second resistance 36.
Power supply is battery in present embodiment.
The operation principle of power-saving circuit of the invention is; when portable set, electronic product shutdown are not used; first switch 31 disconnects; load blocks 40 are powered off; now the base stage of triode 32 is in low level, and triode 32 is not turned on, now the no power of magnet coil 331 of relay 33; second switch 332 is off, and battery protection module 20 is powered off.
Power-saving circuit of the invention; by setting triode, relay and the combination of switch; make after load blocks are stopped; current potential reduction, triode ON, adhesive switch makes battery protection module stop power supply after relay power; make portable set, electronic product after shut down; battery protection module is also disconnected with battery, reduces the power consumption of battery, improves the use time of battery.
