ELECTROHYDRODYNAMIC MULTI-SPRAY HEAD APPARATUS

WIPO Patent Application WO/2023/016072

A1

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 film manufacturing is implemented, and the surface is flat and uniform and does not have bumps and pits; and a multi-spray heads mode is adopted to improve the yield rate, such that the efficiency of thin film manufacturing is greatly improved, and the production capacity of an industrial field is improved.
