Description

Technical Field

[0001] The utility model relates to the field of ink cartridges, in particular to an ink cartridge for an inkjet printer. Background Art

[0002] Ink cartridges, as the core consumables of inkjet printers, are widely used in many fields such as personal homes, offices, education, advertising design, publishing and printing, and industrial manufacturing. They accurately print text, patterns and other information on media such as paper, cloth, and plastic by spraying ink, and are an indispensable part of modern printing technology.

[0003] Inkjet printing has been increasingly widely used due to its advantages in printing speed and printing resolution. Ink cartridges are functional components for storing and guiding ink in inkjet printers, and are also consumable components. In actual use of printers, in addition to the cost of daily maintenance, the main cost comes from the consumption of ink cartridges. Existing ink cartridges are provided with a accommodating cavity inside, in which solid adsorbents are placed for absorbing ink. Therefore, the amount of ink stored in each ink cartridge is mainly determined by the capacity of the solid adsorbent to absorb ink. Since the amount of ink that the solid adsorbent can absorb is limited, the service life of existing ink cartridges is too short, and the cost of using printers is significantly increased.

[0004] However, the existing ink cartridges play an important role in printing, but some defects are still exposed during use. Due to the design limitations between the ink chamber and the nozzle in the existing ink cartridges, in the ink cartridges that have been used for a long time, there are ink precipitation, impurity accumulation and other reasons in the internal ink chamber. When the precipitated ink passes through the ink chamber for use, the ink usage effect is not good, resulting in the ink being difficult to be effectively used, thereby affecting the printing quality. In addition, the structure of the existing ink cartridge for filling ink is not easy to pre-filter, which aggravates the precipitation phenomenon in the ink chamber and affects the quality of ink use.
