Description

[Detailed Description of the Invention] This invention relates to an improvement of a charging device for a small rechargeable electric device using a solar cell.

Conventionally, this type of small electrical equipment generally includes electric shavers, pocket radios, and stationary lights, which have solar cells integrated into their main bodies. Therefore, when charging these electrical devices, the electrical devices are placed in a place exposed to direct sunlight and the sunlight is applied directly to the solar cells. However, in this case, the exterior body of the electrical equipment, especially the plastic body, is likely to deteriorate due to ultraviolet irradiation and high temperature of the atmosphere when receiving light. In addition, each time the device is charged, it is troublesome to have to find a suitable place, whether indoors or outdoors, that is exposed to direct sunlight and where the small electrical device can be left completely unattended.

Focusing on this fact, this invention separates small electrical equipment and solar cells, placing the small electrical equipment in a fixed position indoors where it is protected from ultraviolet rays, and placing the solar battery in a fixed position outdoors where it is exposed to direct sunlight or next to a window. The object of the present invention is to provide a charging device for a rechargeable small electrical device using a solar cell, which can prevent deterioration of the small electrical device due to ultraviolet rays and simplify the charging operation by allowing each device to be installed separately.
