Description

Improved ink cartridge and improved method thereof

The present invention is based on a Chinese Utility Model Patent Application No. 200520119879. filed on Dec. 1, 2005, the content of which is hereby incorporated by reference.

SUMMARY OF THE INVENTION The present invention is directed to an improved ink container for an ink jet printer and an improved method thereof, particularly for an ink cartridge for controlling a heat generating device or a piezoelectric device to perform thermal expansion ink jet or compression expansion ink jet using a integrated circuit chip. Background technique

Inkjet printers are a common type of office equipment, and the ink cartridges that come with them are available in a variety of styles. Judging from the way the ink cartridge is coupled to the print head nozzle, it can be divided into a composite ink cartridge and a split ink cartridge. The latter separates the ink cartridge body and the print head nozzle, that is, the print head nozzle is disposed on the ink cartridge carriage, and the ink cartridge body is placed in a separate state from the print head nozzle before being loaded into the carriage, only when the cartridge body is After loading the carriage, it communicates with the nozzle of the print head through the corresponding ink connection passage, and the ink cartridge body supplies ink to the nozzle of the print head through the ink connection passage on the carriage; the former, the ink cartridge body and the print head containing the ink The nozzles are arranged to be arranged, that is, the print head nozzles are disposed on the corresponding side walls of the ink cartridge body, and the ink nozzles and the pressure adjustment mechanism are respectively disposed through the ink cartridge body, and the print head nozzles communicate with the ink storage chambers in the ink cartridge body, and the print head nozzles pass through the ink cartridge body. The ink connection channel or the like directly obtains the ink supply.

Referring to Figures 1, 3 and 4, Figure 1 shows a prior art composite ink cartridge 1 in which a plurality of circuit connection contacts are distributed on one side wall of the ink cartridge body 4 by means of an adhesive such as glue. A circuit board 3 prepared of a flexible material is attached to the side wall. On the bottom wall of the ink cartridge body 4, an ink supply port 42 composed of a cavity wall 41 communicating with the ink storage chamber inside the ink cartridge body 4 is disposed. At the end face of the chamber wall 41 facing the recording medium 43, the head nozzle 2 prepared of the flexible material is stuck thereto by means of an adhesive such as glue. The flexible material sheet on which the print head nozzle 2 is located is simultaneously provided with a chip composed of a microchip, and the print head nozzle 2 and the microchip chip are integrally provided on the flexible material sheet. Electrical connections are made between the integrated circuit chip and the electrical contacts on the circuit board 3 by corresponding printed circuits. After the ink cartridge 1 is loaded into the printer carriage, the electrical contacts on the circuit board 3 are in contact with the corresponding electrical contacts on the printer, and in electrical communication with the integrated circuit chip through the printed circuit on the flexible material sheet. ·

Referring to Figures 2 and 4, the print head nozzle 2 is provided with six rows of circular nozzles 21 of 0. 025 mm extending in the same direction, which are opened on the microchip chip, and the adjacent nozzles 21 are not connected to each other. Every

1

Confirmation The two rows of nozzle rows 22 form a nozzle group 23. The nozzle rows 22 within a nozzle group 23 have a predetermined distance between each other. The distance between adjacent nozzle groups 23 is greater than the distance between nozzle rows 22. 01毫米的圆圆孔孔24。 The first embodiment of the first embodiment of the first embodiment of the first embodiment of the present invention. The long side of the oblong through hole 24 is in the same direction as the above-described extending direction. These oblong through holes 24 are used for the auxiliary positioning of the print head nozzle 2 on the cavity wall 41 of the cartridge body 4. The adjacent oblong through holes 24 are also not in communication with each other. The arrangement relationship of the oblong through-hole row 25 and the oblong through-hole row group 26 is similar to that of the circular nozzle 21.

When the inkjet printer cartridge 1 is assembled, glue is applied to the end face 43 of the chamber wall 41 facing the recording medium, and the corresponding side wall of the cartridge body 4 for receiving the circuit board 3, and then the print head nozzle 2 is subsequently applied. And the circuit board 3 is bonded to its corresponding position at the same time. After the ink cartridge 1 is assembled, the nozzle 21 of the head nozzle 2 communicates with the ink supply port 42. The periphery of the head nozzle 2 and the position of the oblong through-hole row group 26 are bonded to the end face 43 of the wall 41 of the cartridge body 4 by glue to one side of the recording medium. The oblong through-hole row group 26 faces the end of the inner cavity of the cartridge body 4 and is blocked by glue. However, due to the small area of the end face 43, a glue with a high viscosity and a fast curing speed must be used to avoid the positioning error of the print head nozzle 2, and the reason why the aperture of the long circular through hole row 26 is small is caused. The glue only closes the port of the one end of the long circular through hole row group 26 facing the inner cavity of the ink cartridge body 4, and it is difficult to flow into the inner cavity of the oblong through hole 24 (see Fig. 4). In this way, in order to overcome the one-time use defect of the inkjet printer ink cartridge and avoid the environmental pollution, the print head nozzle 2 with the integrated circuit chip often causes the print head nozzle 2 to loosen during the subsequent recycling process. Causes poor printing or even complete disposal. According to the usage information fed back by the customer, in the case where the print quality is degraded, the print head nozzle 2 loosens a large proportion, which is close to 80%.
