Abstract

A self-generating flashlight mainly includes a housing defining an inner space; a generator set accommodated in the inner space of the housing and including a hand-pull starter cord, and a pull ring connected to an outer end of the starter cord; and a lighting set including a light-emitting body, a control switch, and a control circuit, and is electrically connected to the generator set via one or more electric wires. When the pull ring is pulled, the hand-pulled starter cord is drawn to drive the generator set to generate an electric power, which is supplied via the electric wires to the light-emitting body for the latter to emit light.

Claims

1. A self-generating flashlight, comprising:

a housing defining an inner space therein;

a generator set being mounted in said inner space defined in said housing, and including a hand-pulled starter cord having a pull ring connected to an outer end thereof, said pull ring being normally bearing against a rear end of said housing; and

a lighting set including a light-emitting body, a control switch, and a control circuit, and being electrically connected to said generator set via one or more electric wires;

whereby when said pull ring is pulled to draw said hand-pull starter cord, said generator set is driven to generate an electric power, which is supplied to said light-emitting body via said electric wires, so that said light-emitting body emits light.

2. The self-generating flashlight as claimed in claim 1, wherein said housing is formed from mated first and second shell.

3. The self-generating flashlight as claimed in claim 1, wherein said housing is further provided at a predetermined position with a control switch opening, and at a front end with a lampshade, and is formed at a rear part into a handle.

4. The self-generating flashlight as claimed in claim 2, wherein said second shell of said housing is provided at a predetermined position with an accessory clip.

5. The self-generating flashlight as claimed in claim 3, wherein said housing further includes a reflection mirror mounted behind said lampshade.

6. The self-generating flashlight as claimed in claim 1, wherein said generator set includes a power-generating member, a flywheel, a transmission shaft, a relay ratchet, a first casing, a second casing, and a driving wheel.

7. The self-generating flashlight as claimed in claim 6, wherein said power-generating member includes more than one contact, to which said electric wires are electrically connected and thereby connect said generator set to said control circuit.

8. The self-generating flashlight as claimed in claim 1, wherein said light-emitting body comprises one or more light-emitting diodes.

9. The self-generating flashlight as claimed in claim 1, wherein said control circuit includes a rectifying unit, an energy-storage unit, a filtering unit, and a voltage-stabilizing unit.

10. The self-generating flashlight as claimed in claim 9, wherein said energy-storage comprises a double-layer capacity providing high capacity.
