Energy-saving self-generating type portable printer and application method thereof

Abstract

The invention relates to the technical field of portable printers, in particular to an energy-saving self-generating type portable printer and an application method thereof. The energy-saving self-generating type portable printer comprises a printer shell, a printing assembly, a self-generating assembly and a control assembly, wherein the printing assembly, the self-generating assembly and the control assembly are arranged in the printer shell; the printing assembly and the self-generating assembly are connected to the control assembly; the printing assembly prints texts or images under the control of the control assembly; the self-generating assembly comprises a battery and a piezoelectric device; the piezoelectric device is connected to the battery and charges the battery; the battery supplies power to the printing assembly and the control assembly; and the self-generating assembly further comprises a thermoelectric device, and the thermoelectric device can absorb heat energy generated in the printing process and convert the heat energy into electric energy to charge the printing assembly, so that the service time of the battery is prolonged. According to the energy-saving self-generating type portable printer, the problem that a portable printer cannot be charged outdoors can be solved, and the application range of the portable printer is widened.

Description

technical field [0001] The invention relates to the technical field of portable printers, in particular to an energy-saving self-generating portable printer and a method for using the same. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element hits the paper, it can be divided into impact printers and non-impact printers. According to the structure of printing characters, it can be divided into full-size character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, it can be divided into serial printers and line printers. According to the technology adopted, it is divided into printers such as cylindrical, spherical, inkjet, thermal, lase...
