  The present invention relates to a manually rechargeable safety power supply device including a power supply device and a player and an electronic data regenerator with manual charging. The manual rechargeable safety power source described here can be applied to various rechargeable batteries or portable appliances and general appliances using an external direct current.

  Currently, portable appliances are becoming increasingly popular. For example, portable radio (radio wave receiver), MP3 audio player, MP4 audio video player, portable personal computer, PS, lighting equipment, laptop personal computer, game machine, cellular phone, toy, liquid crystal display television (LCD TV), etc. I can do it. Most of these portable appliances are powered by rechargeable batteries, and at the same time they can be powered by a DC power supply (or convert a general supply of electricity to DC electricity using a portable transformer) It is very convenient to use. Manufacturers are constantly researching various high-capacity and long-lasting rechargeable batteries to increase battery life and make them more convenient. Research has continued from nickel metal hydride batteries to recent lithium batteries, but the duration is still limited. There will be many experiences that have impacted use due to sudden battery loss. Can be used in places where electricity is inconvenient, such as in trains, remote areas, in the mountains, at sea, etc., where there is no public electricity supply, if the battery runs out and there is no place to buy ordinary batteries It falls into a situation without electricity. Smaller is more fun, larger is more inconvenient for work and life, and can lead to unexpected and serious consequences. At the same time, all ordinary batteries used in players with audio / video playback functions are carbon or alkaline batteries. As is well known, these batteries are relatively inexpensive, but cause irreparable damage to the environment.

  In the present invention, a manually rechargeable safe power source is realized. Based on the existing technology, this combines the functions of direct charging and manual charging, and concentrates them on the same power supply device. Specifically, it comprises an electric circuit for manual power generation and an output interface for charging a rechargeable battery. The output of the manual power generation electrical circuit is connected to the output interface through the electrical circuit. There is also a DC power interface. It connects to the output interface through an electrical circuit and charges the rechargeable battery with an external power source. Based on these, the safety charging electric circuit is further increased to ensure safety. Further, by increasing the number of USB interfaces, a DC power supply interface function and a data transmission interface function are provided for a player having an audio / video playback function, which is very easy to use.

  The present invention can be applied to various electronic data reproducing machines such as MP3, MP4, and electronic book reader. Where public electricity or DC electricity can be used, charging can be performed with a DC power interface, and when public electricity or DC electricity is inconvenient, manual charging can be performed with the manual rechargeable safety power supply device of the present invention. . Alternatively, a stable work current can be sent directly to portable appliances, which greatly increases convenience. The safety electric circuit of the present invention is very safe because the system automatically disconnects the electric supply circuit after the charging battery is charged.
