Ink jet head, has perforated plate with small ink outlet around main ink outlet, in which small heating resistor is provided, where small resistor surrounds main heating resistor and forms isolating wall to increase energy of main resistor

摘要

The head has a perforated plate (200), which consists of a main ink outlet (201) in which a main heating resistor (300) is provided, where the resistor (300) has an curved front face. The plate exhibits a small ink outlet (202) around the main ink outlet, in which a small heating resistor (301) is provided. The resistor (301) surrounds the resistor (300) and forms an isolating wall to increase the energy of the resistor (300).
