Hand-operated self-generating electric torch

Abstract

One kind shaking from the electricity generation flashlight, contains has the shell, the reflector, the switch, folds the crank, its characteristic lies in also contains has group or the multi- groups sends the photosource, the shell interior and the base establishment has the kinetic energy transforms as the electrical energy electric power facility and the stored energy installment. The above electric power facility including folds the crank, the speed-up gear cluster, the generator and the electric circuit board. The stored energy installment is or many may imitate the battery, also may be or many electric capacities. By will fold the crank to actuate the speed-up gear cluster revolution, the speed-up gear cluster to rotate the kinetic energy which will produce to transmit again gives the generator, in will turn through the electric circuit board the alternating current the direct current, finally sufficient Chu Daoke in the sufficient battery or the electric capacity, like this provides the regulated supply to the flashlight to cause its to be possible a longer time continuously to use.

Description

technical field [0001] The invention relates to a flashlight for lighting, in particular to a self-generating flashlight. Background technique [0002] At present, most of the flashlights that people use mostly adopt disposable dry batteries to provide lighting power as a power supply. Due to the short service life of the battery, this flashlight needs to replace the battery frequently, which is uneconomical. When people go out on a trip and cannot replace the battery in time, they will lose their proper lighting effect, which makes it inconvenient to go out. When the flashlight is not used for a long time and the battery is forgotten, the electrolyte in the battery will be precipitated, which will corrode and damage the flashlight. In addition, waste batteries will bring great pollution to the environment. [0003] Now, there are also some self-generating flashlights on the market. These flashlights convert kinetic energy into electricity with the press of the hand or b...

AI Technical Summary

Problems solved by technology

Relying on the clenching and loosening of the hand to power the flashlight, the light emitted by the flashlight is intermittent, which is not suitable for groups with weak hands or fingers

The flashlight that generates electricity by pressing or clockwork is limited by the size of the external force or the structure of the clockwork spring, so it cannot be used continuously for a long time.
