Abstract

The present invention is rechargeable flashlight in improved structure. It includes casing, electric bead, charging mechanism and plug, and the casing has rectangular opening and covering plate on one side. It has its rechargeable battery replaced and recharged and may be used also as DC power source for radio-receiver recorder and other electric appliance.

Description

technical field [0001] The invention relates to a torch, in particular to an improved structure of a rechargeable torch capable of replacing a rechargeable battery in the torch. Background technique [0002] Ordinary flashlights generally use dry batteries as a power source. Due to the short service life of dry batteries, they cannot be recharged after the chemical energy is used up, so the cost of use is high, and dry batteries need to be replaced frequently. And the waste battery after use is very serious to environmental pollution, because there are heavy metals such as mercury, mercuric chloride, mercurous chloride, cadmium, lead, zinc and strengthening agent manganese dioxide in the waste battery, also have copper and charcoal. Among them, mercury, mercuric chloride, mercurous chloride, cadmium, lead and other metals are the most harmful to the environment. For example, burning waste batteries will pollute the air, and burying them will pollute groundwater and soil, and...
