Description

Ϊ 277525 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a print wafer, and more particularly to a print wafer applied to an ink jet printer. [Prior Art] • The promotion of computer multimedia technology and the development of digital electronic devices, print output devices such as printers #6, not only become a simultaneous output for texts, or digital photos. , turn out, set business office, home entertainment and other functions of the body. The 4 τ ink printer has the advantages of low price, easy operation and low noise, and can be printed on various inkjet media such as paper and photo paper. It is an economical and effective color printing output device. Therefore, it is widely used. - Generally speaking, the printing quality of the inkjet printer depends on the volume of the ink droplets, the shape of the ink droplets, and the number of printing nozzles, etc., all related to the design of the ink g • especially the (four) column The structural design of the printed wafer to release ink droplets to the inkjet media is a major consideration for ink cartridge design. In the case of the existing thermal bubble inkjet technology, the design of the central ink supply flow path is mostly used, thereby increasing the number of orifice arrays to improve the resolution of the six ink jets. Please refer to the first drawing, which is a schematic view of a conventional ink jet head structure using a central ink supply flow path, as shown in the drawing, 1277525. The ink jet head 1 is composed of a printing wafer 11 and an orifice plate 12. The two opposite sides of the print wafer 11 have a plurality of pads 111, and the center of the print wafer 11 is provided with a central ink supply path 112 parallel to the plurality of pads 111 on both sides. The opposite sides of the ink flow path 112 are provided with a plurality of ink chambers 113 and a plurality of heating resistors (not shown). The ' orifice plate 12 has a plurality of orifices 121, and the orifices 121 are positioned relative to the plurality of ink chambers 113 on the wafer 11, so that the wafers 11 are assembled with the orifices 12 and When it is disposed at the ink outlet (not shown) of the ink cartridge, the ink flows from the central ink supply passage 112 to the plurality of ink chambers 113 on both sides thereof, and is heated by a heating resistor (not shown). The corresponding orifices 121 on the orifice plate 12 are sprayed onto the inkjet medium. • Printing of the wafer π using the central ink supply path 112 has a higher resolution, but requires a process such as sand blasting, laser cutting or etching to form the central ink supply path 112 on the printing wafer 11. However, the cleanliness of the sandblasting process is low, the processing cost of the laser is expensive, and the etching makes the structure of the printed wafer 11 relatively fragile, thereby increasing the processing and manufacturing costs. Moreover, in order to reserve the space to form the central ink supply path 112, the printing of the wafer u requires a large volume, which will increase the manufacturing cost of the printing chip u. • On the same day, since the ink of the central ink supply path 112 must be supplied to the ink chambers 113 on both sides simultaneously, the ink can be ejected from the ejection holes 121 to the inkjet medium, so that the ink supply is not easily smoothed. Or the situation of uneven ink supply. In order to solve the above problem of the central ink supply flow path, a printed wafer using a side ink supply flow path has been exhibited. Please refer to FIG. 2, which is a conventional ink jet head using a side ink supply flow path. The structure shows: 1277525.

The orifice plate 22 has a plurality of nozzle holes 221 corresponding to the ink chamber 213. Therefore, when the print wafer 21 and the orifice plate 22 are assembled and disposed on the ink outlet (not shown) of the ink cartridge, The ink flows from the side ink supply channel 212 of the printing chip to 21 to a plurality of ink chambers 213, and is heated by the heating resistor and then sprayed onto the inkjet medium by the corresponding nozzle holes 221 of the orifice plate 22. . • However, the print wafer 22 using the side ink supply path 212 does not need to be sandblasted, lasered, or etched, and its structure is stronger than that of the central ink supply. The size is also relatively small, which has the advantages of reducing the processing cost and material cost of the printing chip 21, but φ is such that the side ink supply path 212 is disposed, and the opposite printing wafer 21 can only use both sides. Since the orifices 221 are configured to be arranged, the number of the orifices 221 of the inkjet head '2 is limited, which indirectly affects the resolution. • Therefore, how to design a print wafer, taking into account cost and resolution, and increasing the number of orifices on a limited print wafer area to increase the print speed, increase print variations, and improve print quality. In fact, there is an urgent need to solve the problem in the related technical field.
