[Technical field to which the device belongs]

 The present invention relates to a kind of flashlight, and more particularly, to a flashlight equipped with one manual generator in parallel to provide a self-sufficient power supply function to the flashlight.

[0002]

[Prior art]

 Conventional flashlights are used for lighting by simply supplying power from multiple dry cells to cause the bulb to emit light, but even if the number of batteries to be installed is increased and the usage time is extended, Could not exceed 4,5 hours, so when using the flashlight for a long time, he had to carry enough spare batteries for replacement and continue to use it. Also, since the power switch is turned off when the flashlight is not used, it is inconvenient to find the switch when it is necessary to use it in the dark. In addition, the disposal of batteries has created environmental pollution and wasted energy sources. As described above, the conventional flashlight is inconvenient and wasteful.

At its lower end, a gear member that meshes with the gear portion of the pull rope rotating wheel is provided, and one concave beveled tank is formed at an appropriate position on the outer circumference of the disk of the transmission member. Plates and rotating columns are installed. A magnet is fitted around the outer circumference of the rotary shaft above the flywheel, and the magnet is installed in an induction coil installed at an appropriate position in the upper casing. As a result, when the pull rope is pulled rapidly to drive the pull rope and rotate the pull rope rotating wheel, at the same time, the transmission member is interlocked to perform several times high-speed rotation, and the above-mentioned rotary column is driven by centrifugal force. The rolling member rolls between the slope of the plate of the beveled tank and the periphery of the circular tank of the flywheel, which causes the transmission member to rotate at high speed integrally by linking the flywheel and the magnet. The induced current generated by this is used for the light emission of the bulb. When the hand is released from the pull handle, the pull rope is newly wound around the pull rope rotating wheel by the force of the twisted spring that has been tightened. The recovery operation of the towline rolling wheel does not affect the continuous rotation of the flywheel because the rotating column rolls back to the lowest position in the slant tank. Therefore, in the self-powered flashlight of the present invention, the magnet is rapidly rotated in the induction coil through the flywheel by pulling the rope, and the induction current can be generated continuously. When the internal battery power is insufficient or when the battery is not installed, it can be self-sufficient in the required situation, and the flashlight can be illuminated for a long time, or if you want to use the flashlight only for a short time, complete It can supply electricity without using batteries, save energy sources, reduce battery usage and thereby environmental pollution.
