Problems solved by technology

[0003] The purpose of the present invention is to provide a flashlight with manual charging. Since the power supply is manually shaken to make the induced current generated by the magnetic bar continuously cut the magnetic force lines of the coil, it not only greatly avoids environmental pollution and harm to the human body, but also does not require Electricity, save a lot of energy and cost, not limited by night time, easy and convenient to use, overcome the waste of resources in existing products, easy to damage clothes, inconvenient to use, unable to charge at night, etc.

Abstract

The invention relates to a hand-cranked rechargeable flashlight, which includes a cylinder body, a power supply part and a lighting part. Rectifier and voltage regulator circuit board, rechargeable electronic battery, switch, LED light-emitting diode. The beneficial effects of the present invention are: since the power supply is manually shaken by the flashlight, the magnetic bar continuously cuts the coil magnetic force line to generate an induced current, which not only greatly avoids environmental pollution and damage to the human body, but also does not require electricity, saving a lot of energy and costs , not limited by night time, easy and convenient to use.

Description

technical field [0001] The invention relates to a hand-cranked charging flashlight. Background technique [0002] There are two main categories of flashlights currently available on the market: flashlights using common chemical batteries and rechargeable flashlights. Flashlights using ordinary chemical batteries generally fail after 2-3 hours of continuous use, and need to be replaced frequently, which costs a lot, and waste batteries will pollute the environment. There are two types of rechargeable flashlights: one is the lead-acid battery rechargeable flashlight, which consumes a lot of electricity when charging, and the acid of the battery will sometimes flow out, harming the human body and clothing, and polluting the environment; the other is solar rechargeable Flashlight, this kind of flashlight must be charged in daylight, and it cannot be charged at night, which is very inconvenient to use. Contents of the invention [0003] The purpose of the present invention is...
