Charger with OCR character recognition function

Abstract

The invention belongs to the technical field of chargers, and particularly relates to a charger with an OCR character recognition function. The charger comprises a charger box, metal pins, a pocket generator, a PCB (Printed Circuit Board), a USB connecting socket, a storage battery and a scanner, wherein the charger box is provided with a cylinder, the cylinder is provided with a sealing piece, the sealing piece comprises two rollers and a driving gear, the driving gear is arranged between the two roller, the outer diameter of the driving gear is smaller than that of the rollers, first threaded holes are formed in the sides, which are away from the driving gear, of the two rollers, and rubber sealing rings are arranged on the circular surfaces of the rollers. The charger can charge electronic equipment and has an OCR character recognition function, and the USB connecting socket can be protected prevented from being eroded by dust when the charger is not in use. In addition, electric energy can be generated by itself, so that the charger can also be used in an environment without mains supply.

Description

technical field [0001] The invention belongs to the technical field of chargers, and in particular relates to a charger with an OCR character recognition function. Background technique [0002] OCR text recognition refers to the process in which electronic equipment (such as a scanner) checks the characters printed on paper, and then uses the character recognition method to translate the shape into computer text; that is, the text data is scanned, and then the image file is analyzed and processed to obtain The process of text and layout information. [0003] The charger is a device for charging electronic equipment. The working principle of a common charger is to connect the mains power through two metal pins. The mains power is converted into the voltage and current required by the electronic equipment through the PCB circuit board, and finally output through the USB connection socket. To the charging line, the charging line can charge the electronic device. However, the t...

[0003] The charger is a device for charging electronic equipment. The working principle of a common charger is to connect the mains power through two metal pins. The mains power is converted into the voltage and current required by the electronic equipment through the PCB circuit board, and finally output through the USB connection socket. To the charging line, the charging line can charge the electronic device. However, the traditional charger only has the function of charging the electronic device, and does not have the function of OCR character recognition, and the USB connection socket of the traditional charger is directly exposed when not in use. In the external environment, it is easy to be eroded by dust, which affects the service life of the charger. In addition, the traditional charger needs to be connected to the mains to use, and cannot rely on its own power generation. In this way, it cannot be used in an environment without mains power, which is extremely inconvenient to use. , in view of the above problems, we propose a charger with OCR text recognition function
