As shown in the second figure, the body u has a plurality of ink supply channels 111 and a lower ink port 112. The assembly 12 is mainly composed of A printing wafer 14 and an orifice sheet 15 are adhered to each other, wherein the printing wafer 14 has a plurality of ink chambers 14 and ink will flow from the ink supply channel (1) into the ink chamber (4) and through the printing wafer 14 After the heating resistor (not shown) is heated, the ink droplets 16 are generated and ejected from the ejection orifices 151 of the orifice sheet 15 onto the surface of the sheet 17, and the assembly 12 is electrically connected to the flexible circuit board by the wires 18. As for the assembly between the conventional assembly 12 and the body U, 6 1277532 is coated with an epoxy resin (Epoxy glue) 19 for sealing around the ink supply channel 111 in the ink supply port 112, and then the assembly 12 is assembled. Correspondingly, the ink port 112 is heat-pressed, so that the assembly 12 is fixed to the inside of the ink port 112 under the body 11, and then an epoxy resin 19 is further coated at the gap between the assembly 12 and the flexible circuit board 13, and It is cured by UV light to fix the assembly 12 and the flexible circuit board 13 (as shown in the third figure).

The epoxy resin 19 is excessively squeezed. In this case, the epoxy resin 19 blocks the ink supply flow path 111 to reduce the ink discharge area and affect the ink supply (as shown in the fourth figure). Second, the assembly member 12 is excessively bent due to the large inclination angle, which causes the wire 18 to be peeled off and the line short circuit to fail to operate normally (as shown in the fifth figure). 3. The orifice sheet 15 cannot reach the level, which causes the ink droplets to be ejected with an excessively inclined angle with the paper surface, and inferior printing results such as fine white lines or uneven color (as shown in the fourth and fifth figures). 4. The epoxy resin 19 is insufficient in the depression height, so that the adjacent two ink supply channels 111 are not completely separated, causing the two color inks to be mixed (as shown in the sixth figure). Therefore, how to develop an ink cartridge that can improve the above-mentioned defects is an urgent problem to be solved.
