Arrayed electrofluid dynamic jet printing head

The utility model discloses an arrayed electrofluid dynamic jet printing head, comprising an ink box and a nozzle plate located in the middle of the ink box to divide the inner cavity of the ink box into an upper cavity and a lower cavity, wherein nozzle holes which are distributed in an array are distributed on the nozzle plate and run through the upper cavity and the lower cavity, ink liquid outlets distributed in an array are correspondingly formed in the bottom face at the lower part of the ink box, an upper electrode is arranged at the lower bottom face of the nozzle plate, a lower electrode is arranged on the lower bottom face of the ink box, so that an electric field is formed in the lower cavity, ink liquid in the upper cavity passes through the nozzle holes and enters the lower cavity to form a jet flow under the action of the electric field of the lower cavity, and the jet flow is jet out through the ink liquid outlets for jet printing. According to the utility model, an electrofluid dynamic jet pri
