Low-carbon and environmentally-friendly printer

Abstract

The invention discloses a low-carbon and environmentally-friendly printer. The printer comprises a laser emitter and a cylindrical main body part. The printer is characterized in that the laser emitter is provided with a high-frequency modulation unit, a data conversion unit and an optical unit which are electrically connected with one another; the high-frequency modulation unit is used for performing high-frequency modulation on a signal output by a computer; the data conversion unit is used for converting a signal output by the high-frequency modulation unit into a character dot matrix signal; the optical unit is used for directly applying focused energy of a laser beam carrying character information to a paper surface; one side of the main body part extends outwards to form a paper discharge part in the shape of a hat brim; a paper inlet is formed in one side, far away from the paper discharge part, of the main body part; multiple rows of heat dissipation holes in one row are formed in the lower part of the paper inlet; a USB interface is arranged on one side of the heat dissipation holes formed in one end of the main body part; a switch is arranged at the end part of the main body part; and a printing progress indication bar is arranged on the upper surface of the paper discharge part. According to the printer, carbon-powder-free printing is realized, so that the printer is low-carbon and environmentally-friendly.

Description

technical field [0001] The invention relates to a low-carbon environment-friendly printer. Background technique [0002] As one of the most important output devices of various computers, the printer has been greatly developed with the development of computer technology and the increasingly perfect user needs. In recent years, various new and practical printers have emerged as the times require, changing the previous dot matrix printers dominating the world. At present, in the field of printers, three mainstream products have been formed: dot matrix printers, inkjet printers, and laser printers, each of which exerts its advantages to meet the different needs of users from all walks of life. [0003] Although the development of printers has brought great convenience to people's lives, the environmental problems and harm to the human body caused by it cannot be ignored. Generally speaking, the toner used in laser printer ink drums contains carbon black In addition to , iron o...

Problems solved by technology

Toner powder can pollute 0.8 cubic meters of land per gram. In addition, the test results of the International Air Quality and Health Laboratory (ILAQH) show that the harmful particles released by some laser printers are as harmful as those released by smoking. Risk of cancer if inhaled too much

[0004] In addition, because the "size" of the toner is very small, whether it is printing under normal working conditions or filling the toner cartridge with toner without protection, some toner will fly into the air and will be sucked into the air. Circulate to the kidneys (the carbon powder is too small, the lungs of the human body cannot filter and excrete it), the harm cannot be underestimated
