Secondary ink box for ink-jet printer

Abstract

The invention relates to a secondary ink box for an ink-jet printer. The secondary ink box comprises an ink box body, the ink box body comprises two ink grooves located in the two sides, the outer sides of the two ink grooves are provided with a front ink cover and a rear ink cover in a covering mode respectively, after the two ink grooves are covered with the front ink cover and the rear ink cover, two independent ink cavities are formed, the ink box body is internally provided with liquid level sensors which are respectively used for detecting the amount of ink in the two ink grooves, the two end parts of the ink box body are respectively provided with cavities, and after the front ink cover and the rear ink cover are covered with the ink box body, each cavity only communicates with one of the ink grooves, and an independent ink cavity is formed. The secondary ink box for the ink-jet printer has the advantages of being light in structure, saving space, containing various kinds of ink, being stable in ink supply and being long in service life.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a secondary ink box for an inkjet printer. Background technique [0002] The printing trolley of the inkjet printer is equipped with a secondary ink cartridge, which is also called a secondary ink cartridge. The ink flows into the secondary ink box from the main ink box, and then the secondary ink box supplies the ink to each nozzle. In order to ensure the normal supply of ink, the secondary ink box is often equipped with a liquid level sensor to detect the amount of ink in the ink box. Supply ink in time when the ink cartridge is short of ink or stop ink supply when the ink volume is sufficient; the structure of the secondary ink cartridge will comprehensively affect the printing quality of the printer. [0003] Chinese patent CN101352972A discloses a secondary ink box for an inkjet printer, including an ink box body and an ink box cover, an ink chamber is arranged on t...

AI Technical Summary

Problems solved by technology

[0005] 1) The ink chamber in the above-mentioned prior art is formed by splicing double cylindrical chambers. When the secondary ink cartridge moves together with the printing carriage, the ink shakes greatly, which will cause the liquid level sensor to fail to truly reflect the ink in the ink chamber. Volume: If the ink volume is low, the ink will rise due to shaking, and the liquid level sensor will detect that the ink volume is sufficient and not replenish the ink volume in time, resulting in lack of ink, which will affect the normal printing of the printer, or it will be detected as overflowing ink and falsely report overflowing. Ink signal; when the ink is sufficient, the liquid level sensor will detect that the liquid level is low and send out a signal of lack of ink to replenish the ink due to the ink shift due to shaking, which may cause ink overflow or ink back suction;

[0006] 2) The air inlet, ink inlet and ink outlet are connected by external joints. After long-term use, ink leakage is likely to occur due to the aging of the seal or the problem of coordination;

[0007] 3) The secondary ink cartridges in the prior art generally can only hold one kind of ink. When a two-color or multi-color pattern needs to be printed, a plurality of secondary ink cartridges need to be arranged on the printing carriage at the same time, which not only makes the secondary ink cartridge occupy The space is too large or the volume of the printing carriage will be increased, and the weight of the printing carriage will be increased, which will affect the printing quality
