Abstract
The utility model relates to a self-help generating environment-friendly flashlight which comprises an enclosure and is characterized in that: A speed-up gear drive mechanism, driven by a reciprocating drum, a small generator and an AC-DC switch-over power supply circuit of generator are equipped in the enclosure. The reciprocating drum consists of a cylindrical body the circumference of which is surrounded by a stay, a rotary shaft equipped inside the cylindrical body, a disk shape of spring sheet with its internal end fixed at the rotary shaft and its external end fixed at the internal wall of the cylindrical body, wherein the terminal end of the stay protrudes out of the enclosure. The flashlight can realize a charging without a power supply from a dry cell and a foreign power supply and act as a lighting device only by the user operating a generating device, which can effectively ease the energy tension situation, in particular to a tension of raw material for the dry cell and reduce the environmental pollution. Where a charging interface adapting with a mobile phone is available, an emergency charging to the mobile phone can be made. Thereby, the utility model is especially suitable for a trip, a field operation and a country or forestry environment which demands a long-term flashlight use against an absent energy supply or for a household emergency for a bright application prospect.
Description
Affiliated technical field
The utility model relates to a kind of flashlight, especially a kind of self-aid generating environment-friendly flashlight.
Technical background
Traditional flashlight is made battery dry up energy is provided, and they have only and just have comparatively ideal brightness when using new dry cell.But the general dry cell life-span has only tens hours, along with the growth of service time can make brightness die down gradually even unglazed, i.e. and the end-of-life of dry cell.Just must abandon after the disposable like this use, not only increase the weight of the particularly burden of raw material energy anxiety of world today's energy shortage, and the old and useless battery after using heaves around environment is also caused quite serious pollution.Occur some chargeable flashlights at present, promptly use battery instead to dry battery charge, but the charging times of battery is limited, then still less the number of times of dry battery charge.Even the dry cell after the charging, service time is also quite short, and chargeable flashlight still needs the power supply support, can not alleviate the problem of the present energy and dry cell raw material anxiety, so effect is all undesirable.
Summary of the invention
The purpose of this utility model provides a kind of self-aid generating environment-friendly flashlight, and it need not dry cell power supply, also need not additional power source and charges, and only needs the user to drive its TRT voluntarily, promptly can be used as lighting device and uses.
The utility model is to constitute like this: it comprises housing, it is characterized in that: be provided with the speed increasing gear transmission mechanism that is driven by reciprocating type rotating cylinder in the housing, small generator and generator AC and DC conversion power supply circuits.Described reciprocating type rotating cylinder is wound with the cylindrical shell of stay cord by the periphery, be located at the rotating shaft in the cylindrical shell and innerly be fixed in the rotating shaft, disc spring sheet that the outer end is fixed on the cylinder inboard wall forms, the end of stay cord stretches out housing.
The active gear wheel of above-mentioned speed increasing gear transmission mechanism is fixed in the rotating shaft of reciprocating type rotating cylinder, and driven pinion is fixed in the rotating shaft of generator, initiatively is provided with drive between gear wheel and the driven pinion.
Above-mentioned generator AC and DC conversion power supply circuits are formed by regulator rectifier circuit, change-over switch, white light-emitting diode with the charging capacitor circuit that white light-emitting diode is in parallel.
Advantage of the present utility model is: novel, technology is simple, with low cost, need not dry cell power supply and additional power source charges, only need the user to drive its TRT voluntarily, promptly can be used as lighting device and use, particularly the dry cell raw material are nervous and reduce pollution to environment to alleviate the present energy effectively; Adopt self-generating device, profile is small and exquisite, is easy to carry, and the situation that the long-time use of needs flashlight lacks energy supply again such as is specially adapted between out on tours, field work and village forest.

The specific embodiment
Introduce concrete device of the present utility model and working condition thereof below in conjunction with accompanying drawing:
With reference to accompanying drawing 1-3, self-aid generating environment-friendly flashlight of the present utility model comprises housing 1, is provided with the speed increasing gear transmission mechanism that is driven by reciprocating type rotating cylinder in the housing, small generator 2 and generator AC and DC conversion power supply circuits 3.Above-mentioned reciprocating type rotating cylinder is wound with the cylindrical shell 5 of stay cord 4 by the periphery, be located at the rotating shaft 6 in the cylindrical shell and innerly be fixed in the rotating shaft, disc spring sheet 7 that the outer end is fixed on the cylinder inboard wall forms, the end of stay cord stretches out housing.The active gear wheel 8 of speed increasing gear transmission mechanism is fixed in the rotating shaft of reciprocating type rotating cylinder, and driven pinion 10 is fixed in the rotating shaft of generator, initiatively is provided with drive 9 between gear wheel and the driven pinion.
During use, spur the stay cord 7 on the reciprocating type rotating cylinder, disc spring sheet 9 is because elastic force, rotating shaft 8 is rotated, the active gear wheel 10 that drives the speed increasing gear transmission mechanism rotates, and, make its quick rotation by drive 9, driven pinion 10 driving small generators 2, mechanical energy is converted to electric energy.Then, when the user unclamps stay cord, reciprocating type rotating cylinder impels its fast reverse revolution under the effect of disc spring elastic restoring force, drive small generator quick rotation and generating through the speed increasing gear transmission mechanism equally.
Small generator 2 rotations produce the alternating current of 8V, obtain the direct current of 11V after diode 12 rectifications, electric capacity 13 filtering, again through after 14 voltage stabilizings of three end integrated circuits farad capacitor 15 being charged.After charging finishes, turn on the power switch 16 and can make white light-emitting diode 11 luminous.
In addition, if add the charger for mobile phone interface, also can carry out emergent charging to mobile phone.
Utility model is novel, and technology is simple, and is with low cost, need not dry cell power supply and additional power source charges, only need the user drive its TRT voluntarily, promptly can be used as lighting device and use, particularly the dry cell raw material are nervous and reduce pollution to environment to alleviate the present energy effectively; Adopt self-generating device, profile is small and exquisite, is easy to carry, and the situation that the long-time use of needs flashlight lacks energy supply again such as is specially adapted between out on tours, field work and village forest, has bigger application prospect.
