Problems solved by technology

[0006] However, with the conventional ink cartridge having the above-mentioned structure, the number of operations of the metal molding process of the ink cartridge 1 increases, and thus the cost of the molding process increases, causing trouble in mass production
In addition, when the long slit 5a is blocked, the air flows to the inkjet head chip through the tube 7, so that it cannot be printed normally.

Abstract

An ink cartridge is provided with a main body divided into an ink chamber filled with ink and a foam chamber receiving an ink absorbent body, an ink head chip disposed at a lower portion of the foam chamber to spray the ink onto a printing paper, a partition forming a passage with a bottom of the main body to pass ink and air therethrough, and dividing an inside of the main body into the ink chamber and foam chamber, and an ink feeding pipe disposed lower than the passage and at a lower portion of the foam chamber to feed the ink in the foam chamber to the ink head chip.

Description

technical field [0001] The present invention relates to an ink cartridge, and more particularly, to an ink cartridge that prevents air from flowing into a print head chip during printing with ink. Background technique [0002] Generally, an ink cartridge of an inkjet printer includes a main body filled with ink, and ink in the main body is sprayed onto paper in a predetermined amount at a time by an ink head chip provided to the main body. [0003] figure 1 The ink cartridge 1 disclosed in US Pat. No. 5,742,311 is shown. refer to figure 1 , The ink cartridge 1 has a two-chamber structure for maintaining negative pressure. The inside of the ink cartridge 1 is divided into a foam chamber 4 containing foam (such as a sponge) 3, and an ink chamber 6 filled with ink 1. The ink chamber 6 and the foam chamber 4 are divided into left and right regions by a partition 5 . Between the lower end of the partition 5 and the inner bottom 1a of the ink cartridge 1, a channel 9 for pass...
