INKJET HEAD AND INKJET HEAD ASSEMBLY INCLUDING THE SAME

摘要

PURPOSE: An inkjet head and an inkjet head assembly including the same are provided to reduce the deviation of the speed and droplet size of discharged ink, since the discharge pressure of ink is uniformly adjusted in a nozzle connected to an ink chamber. CONSTITUTION: An inkjet head and an inkjet head assembly including the same comprise an ink-jet head, a pressure chamber(224), a piezoelectric(250), a pressure control channel, and an ink cartridge. Multiple nozzles discharge ink-jet head ink. The pressure chamber stores ink and is formed with flow paths that face each other in the width direction thereof. The piezoelectric provides driving force for discharging ink through each nozzle connected to the pressure chamber. The pressure control channel controls the pressure of the ink discharged though each nozzle. The ink cartridge is coupled with the ink-jet head to provide ink to the ink-jet head.
