ELECTROHYDRODYNAMIC MULTI-SPRAY HEAD APPARATUS

Disclosed is an electrohydrodynamic multi-spray head apparatus, comprising an ink seat, sealing connectors, a flow channel plate, precision spray heads, and a printing base. The sealing connectors used for connecting to enable ink to flow in and out are provided on an upper surface of the ink seat; the flow channel plate for guiding the ink is provided on a lower surface of the ink seat; the flow channel plate is provided with a plurality of precision spray heads; the plurality of precision spray heads are all communicated with the flow channel plate; the printing base is provided below the precision spray heads at an interval; nozzles of the plurality of precision spray heads are all provided facing the printing base; a power supply apparatus is separately electrically connected to the ink seat and the printing base. In the present apparatus, the ink is dispersed into a large number of micro-nano-scale small droplets in a mode of high voltage of a ten thousand volts level, such that micro-nano-scale thin fil
