Method for refilling ink to ink box and filling tool

Abstract

The invention relates to a method for refilling ink to an ink box, comprising the following steps: 1, sealing an ink filling opening of the ink box with an ink supply opening of an ink storage container of an ink filling tool incompletely filled with ink in a sealing way, sealing a suction unit with the ink storage container of the ink filling tool and sealing the ink box; 2, sucking air inside the ink storage container of the ink filling tool with the suction unit; and 3, releasing the suction unit, wherein the ink box automatically absorbs ink in the ink storage container of the ink fillingtool as a result of air pressure balance. As air in the ink box is absorbed based on the air pressure principle, and the absorbed pressure is cancelled to press ink in the ink storage container inside the ink box based on the air pressure principle, residual ink in the ink box is not needed and the whole process is carried out under a sealing state, thereby solving the technical problems of ink waste and environmental pollution caused by sucking residual ink inside the ink box by the prior ink refilling method. The invention also provides an ink filling tool used in the method.

Description

technical field [0001] The present invention relates to a method and filling tool for refilling ink into an ink cartridge. Background technique [0002] In a printing apparatus such as an inkjet printer, printing is performed by ejecting liquid ink onto a printing medium. A printing device, especially a small printing device for home use, stores ink in an ink cartridge, and then continuously supplies ink from the ink cartridge to the print head, thereby printing. However, since the device must be miniaturized, the ink cartridges (such as Figure 1 shown) itself is designed to be small, and its capacity is also limited. Therefore, the ink cartridges need to be constantly replaced or replenished with ink. [0003] From the perspective of efficient use of resources, it is preferable to replenish the ink cartridges instead of replacing the ink cartridges. However, the actual situation is that when consumers refill ink cartridges, the method of injecting directly with a syringe...
