Abstract
The utility model discloses a rocking-generating electric torch, which belongs to an illuminating tool. A generating core is arranged in a cylinder body, and the front end of the generating core is provided with a bulb and a circuit board. Bridge rectifiers are arranged on the circuit board side by side. A coil is wound on the back half section of an insulating cylinder of the generating core, and a constant magnet rod which can be slid in the coil is inserted in the coil. The defects of the prior art are overcome by the utility model, and an electric torch is rocked, which enables the constant magnet rod to be slid for several times in the coil, and thus electricity can be generated, and the bulb can have sufficient brightness. Thus the utility model has the advantages of convenience and rapidness, and facility can be brought to life.
Description
Technical field
The utility model belongs to illuminations, particularly a kind of power generation flashlight that rocks.
Background technology
Existing flashlight all is to use dry cell power supply, also power with rechargeable battery, but dry cell finite capacity, service time is not long, and rechargeable battery is longer relatively service time, and the electric weight deficiency can be charged additional, yet the charging interval is longer, time used is short, and is still inconvenient, do not need to charge and voluntarily the flashlight of generating also do not emerge.
Summary of the invention
The purpose of this utility model provides a kind of power generation flashlight that rocks, and described flashlight is made up of stack shell, bonnet, protecgulum and battery.In stack shell 5, place the generating core, said generating core is an insulating cylinder, front end at this insulating cylinder is installed bulb 11 and circuit board 9, two bridge rectifiers 13 also are listed on the circuit board 9, switch 8 is contained in the circuit board middle part, the second half section of insulating cylinder goes up and twines first coil 4 and second coil 3, permanent bar magnet 2 inserts in the coil, slide at two coil inner chambers, at the sliding cavity two ends yielding rubber pad 6 is housed, the fixing rubber membrane 7 of Push switch on preceding half section of stack shell 5, the output of rectifier 16 is connected by switch 8 and bulb 11.
Described second coil, 3, the first coils 4 respectively and rectifier separately 16 join.
The output of described two rectifiers 16 and storage capacitor 13 threes also connect; The another side that is connected in series switch 8, resistance 15, bulb 11 and output in rectifier output on one side connects into the loop.Another side serial connection light emitting diode 14 is connected with an input of any one rectifier 16 with resistance 15 backs.
Convex lens 12 are housed in the protecgulum of described flashlight.
The beneficial effects of the utility model are to have overcome the deficiencies in the prior art, as long as rock several flashlights down, permanent magnet slides several times in coil, just can generate electricity, and makes bulb that enough brightness be arranged.Convenient, fast, bring great convenience to life.

Fig. 1 is the structural representation of flashlight;
Fig. 2 is the circuit theory diagrams of Fig. 1.
The specific embodiment:
The utility model provides a kind of power generation flashlight that rocks, and described flashlight is made up of stack shell, bonnet, protecgulum and battery.In stack shell 5, place the generating core, said generating core is an insulating cylinder, front end at this insulating cylinder is installed bulb 11 and circuit board 9, two bridge rectifiers 16 also are listed on the circuit board 9, switch 8 is contained in the circuit board middle part, the second half section of insulating cylinder go up winding around 4 and second coil, 3, the second coils, 3, the first coils 4 respectively and rectifier separately 13 join.Permanent bar magnet 2 inserts in the coil, slides at two coil inner chambers, at the sliding cavity two ends yielding rubber pad 6 is housed, and floatless switch is pressed rubber membrane 7 on preceding half section of stack shell 5, and the output of rectifier 13 is connected by switch 8 and bulb 11.
The output of described two rectifiers 16 and storage capacitor 13 threes also connect; The another side that is connected in series switch 8, resistance 15, bulb 11 and output in rectifier output on one side connects into the loop.Another side serial connection light emitting diode 14 is connected with an input of any one rectifier 13 with resistance 15 backs.
Convex lens 12 are housed in the protecgulum of described flashlight.
