[0041] The arrayed electrofluid jet printing device includes an arrayed nozzle, a high-voltage source, a high-voltage switch array, a drive module, a digital main control module, and a host computer, such as figure 2 shown, where:
[0042] The arrayed nozzle adopts a protruding microneedle structure, including 8 nozzles with independent lead-out electrodes, with a spacing of 1mm. The power supply method is directly powered by the liquid, and the turn-on voltage is about 1800V.
[0043] The high-voltage source is divided into two parts: the working signal source and the control signal source. The working signal source is a combination of a signal generator and a high-voltage amplifier, and the control signal source is a high-voltage DC source.
[0044] The high-voltage switch array is composed of 8 groups of high-voltage dry reed relays connected in parallel, which correspond to 8 nozzles one by one, and each group contains two high-voltage switches, in which the output end of...
