Problems solved by technology

[0004] However, in conventional separate type ink cartridges, only the filter cannot be replaced, since the filter for filtering foreign matter and air bubbles contained in the ink in the ink flow path is installed inside the print head, so due to the structure of the print head, cause, it is also not possible to increase the size of the filter
[0005] Also, if air-containing ink (for example, air passes through the nozzles or enters the ink when the ink tank is removed and / or installed) passes through the filter inside the printhead, there will be a significant pressure loss before and after the penetration of the ink
[0006] Also, since the printhead is always installed on the inkjet printer, the filter cannot be replaced when its lifespan expires

Abstract

An ink tank to store ink which is supplied to a printing head installed to an ink jet printer, and to be detachably mounted to the ink jet printer, includes a main body to store the ink and having an ink outlet part, a tubular body which is accommodated in the main body and includes a first end part which communicates with the ink outlet part and a second end part which includes an ink inlet facing a bottom surface of the main body, and a filter which is connected to the tubular body.

Description

technical field [0001] The present invention relates to an ink tank and an ink jet printer using the ink tank for simplifying filter replacement and reducing pressure loss. Background technique [0002] A conventional inkjet printer ejects ink to form an image, and includes a print head formed with nozzles for ejecting ink, and an ink tank that supplies ink to the print head. There are two types of ink cartridges, they are: integrated ink cartridges and detached ink cartridges, integrated ink cartridges have an integrated print head and ink tank body, which are installed and removed as a whole; and detached ink cartridges, only the ink cartridges can be detached from the printer or installed to printer, and the printhead is installed on the printer. [0003] In the separate type ink cartridge, if the ink tank is mounted to the print head, an ink flow path may be formed from the ink tank to the nozzle of the print head. [0004] However, in conventional separate type ink ca...
