Ink cartridge for ink jet printer

Abstract

The invention discloses an ink cartridge for an ink jet printer. The ink cartridge comprises an upper cartridge and a lower cartridge which are tightly connected, wherein the upper cartridge comprises a positive pressure cavity and a negative pressure cavity which are not communicated, an ink inlet is formed in the positive pressure cavity, an ink return hole is formed in the negative pressure cavity, the lower cartridge is provided with a groove and at least five pairs of sprayer inlets and sprayer outlets which are matched with sprayers, the groove is used for separating the sprayer inlets from the sprayer outlets, the sprayer outlets are opposite to the positive pressure cavity, the sprayer inlets are opposite to the negative pressure cavity, a negative pressure detection hole is formed in the negative pressure cavity and is connected with a pressure detection device for detecting the pressure of a negative pressure, and a temperature heating device for heating ink in the ink cartridge and a temperature detection device for detecting the temperature of the ink are arranged on the ink cartridge. The ink cartridge has the advantages of greatly improving the problems of ink deposition and instable flowing, reducing the blockage of the sprayers, and greatly reducing the production cost because ink cartridges of different specifications are designed according to the demands to adapt to requirements on different printing widths.

Description

technical field [0001] The invention relates to the field of inkjet printing equipment, in particular to an inkjet printer ink box. Background technique [0002] Due to imperfect design, the existing inkjet printer ink cartridges are prone to ink deposition, poor flow affects the stability of ink supply in the ink path, and in severe cases, it will also cause blockage of nozzles and other components, which not only affects normal production, but also increases the equipment cost. Use and maintenance costs. [0003] The mainstream ink cartridges on the market generally only support the setting of 5 nozzles, and the capacity is small. If you want to increase the printing width of 1 or 2 nozzles, you need to add a set of ink supply mechanism and ink cartridges, which greatly improves the performance of inkjet printers. The production cost; and the ink cartridges that support more nozzle settings have higher requirements on the ink supply system. Not only is the design of the i...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an inkjet printer ink cartridge, which aims to solve the problem that the existing ink cartridges are easy to cause ink deposition and affect the printing quality; too many or too few nozzles of the ink cartridge are not conducive to reducing the production cost of the inkjet printer.
