Example Embodiment

[0012] The technical features of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0013] Such as figure 1 A self-powered hand-held torch shown includes a light emitter 1, a condensing bowl, a power storage device and a power generating device. The power generating device is composed of a permanent magnet 3 and a tightly wound coil 2. The permanent magnet 3 is placed Sliding in the coil 2; the permanent magnet 3 is connected to the inner wall of the coil 2 by a number of symmetrical elastic bands 4 around the circumference, and the permanent magnet 3 is suspended in the coil 2.

[0014] When in use, if it shakes along the axis of the coil 2, the permanent magnet 3 vibrates at a high speed on the axis of the coil 2 to generate current, which is supplied to the power storage device, and then the light emitter 1 is powered.

[0015] Because the elastic band 4 suspends the permanent magnet 3 in the coil 2, the friction bet...

Abstract

The invention discloses a self-power-generating handheld torch, comprising a light emitter, a light focusing bowl, an electric storage device and a power generating device, wherein the power generating device consists of a permanent magnet and coils tightly wound; the permanent magnet is slidably placed in the coils; the periphery of the permanent is connected with the inner walls of the coils by means of a plurality of symmetric elastic belts; and the permanent magnet is suspended in the coils. The self-power-generating handheld torch provided by the technical scheme of the invention has the advantages that the structure is simple; simpleness, convenience and practicability are ensured; and the friction of a power generating device can be reduced, kinetic energy is increased, and the power generating efficiency is greatly improved.

Description

technical field [0001] The invention discloses a flashlight, in particular to a self-generated and charged flashlight. Background technique [0002] Flashlight is a common article in people's daily life, and present flashlight generally has two kinds, and a kind of is dry cell type, and a kind of is storage battery type. The dry battery type has a simple structure and is easy to use, and can continue to illuminate by replacing the dry battery in time; the battery type flashlight has a long service life, no need to replace the power supply, and can be charged at leisure. But they also have their own problems: if the dry battery type flashlight is used up and there is no dry battery, it can only be a waste; and the battery type, the charging time is long, and the flashlight itself is also very heavy. The problem of power outage in the middle. Therefore people have designed the flashlight of voluntary power generation charging illumination, as pinching rechargeable type, shak...
