Problems solved by technology

[0006] In summary, although the design of the boss 6 of the known ink cartridge can reduce the amount of residual ink, its design change needs to involve the modification of the mold, so the design variability is not good, and the foam material near the side of the boss 6 5. The porosity drops sharply due to being stretched by the convex post 6, which makes the capillary force blocked, resulting in ink residue behind the blocked area. Therefore, the technology for how to reduce the amount of residual ink still needs to be developed

Embodiment Construction

[0010] Such as image 3 , Figure 4 and Figure 5 As shown, the porous material 10 of the ink cartridge of the present invention is used to be arranged in the ink holding space 4 of the ink cartridge, the porous material 10 includes a body 11, the top surface 12 is larger than the bottom surface 13, and the bottom surface 13 resists the bottom surface 13 inkjet head 3 of the ink cartridge.

[0011] Such as Figure 4 and Figure 5 As shown, the porous material 10 is installed in an inkjet head 3, the inner boss 6 of which does not protrude from the ink cartridge of the ink holding space 4, and the bottom surface 13 resists the boss 6 of the inkjet head 3, and the The height (A) of the body 11 is greater than the height (B) so that the bottom 13 can produce a higher compression ratio when resisting the boss 6, the height (A) is the height from the top surface 12 to the bottom surface 13, and the body 11 The height (B) of the ink cartridge is higher than the height (C) of th...

Abstract

A porous material arranged in the ink cavity of ink box for guiding ink features that its main body has a top surface greater than its bottom surface, which is squeezed by ink box to generate a local high-porosity region for collecting ink in this region. As the ink-collecting region has stronger capillary force, the ink is guided to flow into the ink-collecting region for supplying ink to ink-jet head.

Description

technical field [0001] The invention relates to a design of an ink box, in particular to a design for diversion of a porous material arranged in the ink holding space of the ink box to absorb ink. Background technique [0002] It is known that the ink-holding design of the inkjet printer ink cartridge can be divided into three types: foam material, air bag and ink bag. The use of foam material has good space adaptability, and it can be applied even in a narrow space Therefore, it is highly valued by the industry. [0003] figure 1 It is a known ink cartridge structure using a foam material, which includes a housing 1, a cover 2 arranged above the housing 1, and an inkjet head 3 located below the housing 1; wherein the housing 1 An ink-holding space 4 is provided for a foaming material 5 and ink to be accommodated in it. The inside of the ink-jet head 3 is provided with a protruding post 6 in the ink-holding space 4. It is known that a rectan...
