Problems solved by technology
[0009] A known ink filling step is to fill the ink into the inkjet cartridge first when the air bag is not pre-inflated. After the ink is filled and the ink filling port is closed, the air bag is inflated so that the air bag can be used. The contraction force of the inkjet cartridge will generate enough negative pressure in the inkjet cartridge, but this method of inflating the airbag after closing the ink filling port will force part of the ink from the inkjet head chip due to the inflation action of the airbag. Extruding the inkjet cartridge not only causes waste, but also pollutes the cleaning of the inkjet head chip
[0010] On the other hand, after the ink is filled, there will be residual air bubbles at the ink outlet of the inkjet cartridge, which will cause the failure of the inkjet cartridge and the failure of the ink filling operation. Therefore, a method and device for filling ink to the inkjet cartridge have been developed to quickly Fill the ink and fix the problem

Embodiment Construction
[0026] At first, take the inkjet box 1 as an example, illustrate the preferred embodiment of the ink filling method disclosed in the present invention, as Figure 1A-1D Shown, the structure of inkjet cartridge 1 comprises:
[0027] The cartridge 11 is a hollow container for storing ink;
[0028] Inkjet head 12, is located at the bottom of cartridge 11, has many tiny ink ejection openings 121, communicates with the inside of cartridge 11 and atmosphere, in order to eject the ink in cartridge 11 to recording medium (as paper or its similar object), a filter screen 122 is also provided near the position of the inkjet head 12 to prevent impurities in the ink from clogging the inkjet port 121 of the inkjet head 12;
[0029] The ink filling port 13 is located on the top surface of the cartridge 11, communicates with the inside of the cartridge 11 and the outside, and serves as an injection channel for ink;
[0030] The air bag 14 is arranged inside the cartridge 11, communicates w...

A method for filling ink in the ink-jet box includes such steps as closing the outward channels except the ink filling inlet, initializing the internal volume to maximum, filling in quantitatively, closing the ink filling inlet, starting the air bag to generate negative pressure in the box, opening the ink jet outlet, regulating the position of ink jet outer to the highest point, and generating positive pressure for exhausting residual air bubbles. Its filling device is also disclosed.
Description
technical field [0001] The invention relates to an ink filling method and device, in particular to a method and a device for filling an ink jet box used in ink jet printing equipment. Background technique [0002] Inkjet printers are already a fairly reliable and efficient printing tool. Generally, an inkjet printer has an inkjet print head that can move back and forth relative to the surface to be printed and eject ink droplets; Print the surface to form the desired image or data content. An ink pen is usually used in this type of printer, which mainly includes two parts such as a cartridge for storing and supplying ink and an inkjet print head. [0003] At present, there are two commonly used systems to enable the inkjet print head to eject ink droplets according to a series of control commands, one is the thermal bubble system, and the other is the piezoelectric system. The inkjet printing heads using the above two systems are all provided with a plurality of microhole...
