An external device for adding ink at constant pressure to an inkjet printer

Abstract

The invention discloses an external device for constant-pressure ink feeding of an ink-jet printer. The external device for constant-pressure ink feeding of the ink-jet printer comprises a box. Baffles dividing the box body into at least two sub-chambers are arranged in the box body. A partition plate is arranged in each sub-chamber and divides the sub-chamber into a first partition bin and a second partition bin. The surface of the second partition bin is provided with an ink feeding opening, an ink outlet and an air guide hole. The bottom of each ink outlet is provided with an ink suction pipe. Each ink outlet is connected with an ink cartridge of the ink-jet printer through an ink conveying pipe. The external device for the constant-pressure ink feeding of the ink-jet printer can complete the ink feeding process under the condition that the ink cartridge is not demounted and continuously and stably provides ink for the ink cartridge of the ink-jet printer, keeps a sprayer of the ink-jet printer wet and prolongs the service life of the sprayer of the ink-jet printer. The problem that ink cannot be fed into the ink cartridge of the ink-jet printer directly and continuously in time can be solved.

Description

technical field [0001] The invention belongs to the technical field of ink-filling devices for ink-jet printer ink boxes, in particular to an external device for stably adding ink to ink-jet printer ink boxes. Background technique [0002] Printers are divided into laser printers and inkjet printers, and inkjet printers can be divided into solid inkjet and liquid inkjet. Liquid inkjet printers can print various desired images and characters by spraying inks of various colors onto the printed paper. Inkjet printers are provided with ink cartridges for storing inks of different colors. The common ink supply method between an inkjet printer and its matching ink cartridges is to insert an ink supply needle with an ink through hole into the ink outlet of the ink cartridge, and the ink supply needle penetrates The sealing layer at the ink outlet is realized by making the ink flow from the ink outlet into the ink through hole in the ink supply needle. The life of the early ink ca...
