Low-cost efficient printer

Abstract

The invention discloses a low-cost efficient printer which comprises an ink box. The ink box comprises a bottom plate, a top plate and a side plate connected with the bottom plate and the top cover. An ink outlet is formed in the bottom plate. A plurality of gas holes are formed in the top cover. A groove is formed in the top surface of the top cover. An ink injection hole is formed in the centerof the groove. The lower end of the ink injection hole communicates with the inner cavity of the ink box. A plurality of elastic sealing plates are arranged on the side wall of the ink injection hole.One end of each elastic sealing plate is fixed on the side wall of the ink injection hole, and the other end of the elastic sealing plate extends downwards to the axis of the ink injection hole. A filter screen is arranged below the ink injection hole. The edge of the filter screen is fixed on the inner wall of the top cover. The ink box of the low-cost efficient printer can be repeatedly used, and the ink injection hole can be prevented from being blocked effectively.

Description

technical field [0001] The invention relates to a printer, in particular to a low-cost and high-efficiency printer. Background technique [0002] A printer (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. The ink cartridge is one of the key components of the printer. The modern ink cartridge mainly refers to the part used to store printing ink in the inkjet printer and finally complete the printing. Existing ink cartridges are usually disposable ink cartridges, which are discarded after use, which not only wastes materials, but also increases the use cost of the printer. Therefore, after the ink cartridges are used up, ink is usually adde...

AI Technical Summary

Problems solved by technology

Existing ink cartridges are usually disposable ink cartridges, which are discarded after use, which not only wastes materials, but also increases the use cost of the printer. Therefore, after the ink cartridges are used up, ink is usually added to the ink cartridges to increase its reuse rate.

Due to the long-term storage or improper storage of the added ink, there will be insoluble suspended particles in the ink, or a viscous suspension will be formed. These suspended particles or suspensions will easily block the ink jet holes of the printer and cause printer failure.
