Abstract

See full text

An arrayed electrohydrodynamic printhead without the extraction electrodes is provided. A printhead is formed by an ink cartridge, a flow channel plate, a nozzle plate, a control electrode layer. The ink cartridge includes an ink inlet, an ink outlet, an installation hole, a flow channel layer inlet, flow channel layer outlet. The flow channel plate has the functions of guiding the ink to flow into the nozzle plate and increasing the potential difference between the nozzles, and includes a flow channel inlet, a flow channel outlet, a drainage channel, and a microfluidic channel. A body of the nozzle plate includes nozzles and nozzle electrodes. The microfluidic channel forms a voltage division unit between each nozzle, so that the voltage on the triggered nozzle is dispersed in the flow channel without affecting other nozzles, and independent and controllable injection of each nozzle is thereby achieved.
