The invention discloses an array electric
fluid power printing head, which comprises an ink box, and a
nozzle plate positioned at the middle part of the ink box and used for partitioning the cavity of the ink box into an upper cavity and a lower cavity;
nozzle holes are distributed in the
nozzle plate in an array mode, and the nozzle holes are communicated with the upper cavity and the lower cavity; the bottom of the lower part of the ink box is provided with ink outlets correspondingly arranged in an array; an upper
electrode is arranged at the bottom of the nozzle plate, and a lower
electrode is arranged at the bottom of the ink box, so that an
electric field is formed in the lower cavity; and the ink in the upper cavity passes through the nozzle holes and enters the lower cavity, the ink forms jet under the action of the
electric field of the lower cavity, and the ink is ejected for printing through the ink outlets. Because the electric
fluid power printing principle is adopted in the array electric
fluid power printing head, the jet
diameter can reach 1 to 10 microns, and the jet is not affected by the
diameter of a nozzle; and the array electric fluid power printing head has large jet dragging force, is suitable for high-
viscosity solution, and does not destroy the material. The array electric fluid power printing head has the characteristics of simple structure, high printing precision and low cost, and has good industrial practicability.
