Flashlight be in people's daily life or not or lack indispensable instrument, at present, flashlight afterbody switch all uses mechanical switch, mechanical switch: adopt mechanical touching mode to change the break-make of circuit, on such as wall, light switch must touch by hand, switch because touching has error, has wearing and tearing, has life-span number of times, and can produce spark, adds and make risk under hazardous environment.And common electronic switch design exists change torch structure, anode introduced torch afterbody and increase torch difficulty of processing and stability.
Utility model content
The purpose of this utility model is to provide a kind of accumulation energy type zero-power torch electronic switching circuit, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of accumulation energy type zero-power torch electronic switching circuit, comprise chip U1, battery U2, diode D1, metal-oxide-semiconductor Q1, resistance R1 and electric capacity C1, described chip U1 pin 3 is connecting valve K1 respectively, resistance R1 and electric capacity C1, the resistance R1 other end connects the G pole of chip U1 pin 6 and metal-oxide-semiconductor Q1 respectively, the D pole contact resistance R3 and output B1 respectively of metal-oxide-semiconductor Q1, the resistance R3 other end connects diode D1 positive pole, diode D1 negative pole connects chip U1 pin 5 respectively, battery U2 positive pole and diode D2 negative pole, diode D2 positive pole connects the S pole of metal-oxide-semiconductor Q1 respectively, battery U2 negative pole, electric capacity C2, output B2 and the electric capacity C1 other end, the electric capacity C2 other end is the connecting valve K1 other end and resistance R2 respectively, the resistance R2 other end connects chip U1 pin 4, described chip U1 executes special inverter for two.
As the utility model further scheme: described diode D2 is voltage stabilizing didoe.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts metal-oxide-semiconductor to control big current, less than standard machinery volume of switch, lightweight, less than ordinary electronic switching circuit power consumption, can reduce standby current is zero, this product adopts continuous electric accumulation energy type form, so do not worry service time and useful life.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of accumulation energy type zero-power torch electronic switching circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical 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 accumulation energy type zero-power torch electronic switching circuit, comprise chip U1, battery U2, diode D1, metal-oxide-semiconductor Q1, resistance R1 and electric capacity C1, described chip U1 pin 3 is connecting valve K1 respectively, resistance R1 and electric capacity C1, the resistance R1 other end connects the G pole of chip U1 pin 6 and metal-oxide-semiconductor Q1 respectively, the D pole contact resistance R3 and output B1 respectively of metal-oxide-semiconductor Q1, the resistance R3 other end connects diode D1 positive pole, diode D1 negative pole connects chip U1 pin 5 respectively, battery U2 positive pole and diode D2 negative pole, diode D2 positive pole connects the S pole of metal-oxide-semiconductor Q1 respectively, battery U2 negative pole, electric capacity C2, output B2 and the electric capacity C1 other end, the electric capacity C2 other end is the connecting valve K1 other end and resistance R2 respectively, the resistance R2 other end connects chip U1 pin 4, described chip U1 executes special inverter for two.
Described diode D2 is voltage stabilizing didoe.
Operation principle of the present utility model is: refer to Fig. 1, and utilization is two executes special inverter composition bistable circuit.The upset of K1 touch key circuits for triggering produces low and high level and controls the effect that metal-oxide-semiconductor break-make reaches switch.(when being the conducting of high level metal-oxide-semiconductor for control, resistance is short circuit.When being the cut-off of low level metal-oxide-semiconductor for control, resistance is open circuit.)
(1) circuit reach pass state switch as follows: when circuit MOS conducting, A2 is high level, and Y2 is low level, and now electric capacity C1 two ends are high level, and electric capacity C2 two ends are low level.When K1 closes, electric capacity C2 charge C1 electric discharge because C2 capacity is much larger than C1, now A2 current potential can K1 close in a flash lower than the negative sense threshold voltage of close special inverter, cause circuit overturn, circuit metal-oxide-semiconductor cut-off.(2) state that circuit closes out switches as follows: when circuit MOS ends, A2 is low level, and Y2 is high level, and now electric capacity C1 two ends are low level, and electric capacity C2 two ends are high level.When K1 closes, electric capacity C1 charge C2 electric discharge because C2 capacity is much larger than C1, now A2 current potential can K1 close in a flash higher than the forward threshold voltage of close special inverter, cause circuit to overturn, the conducting of circuit metal-oxide-semiconductor.
