Problems solved by technology

[0003] However, when electrohydrodynamic jet printing prints solutions with larger solute particles or volatile solvents, the nozzles will be clogged, resulting in inability to print continuously for a long time; at the end of printing, when the solution in the nozzle is not used up, directly Leave it on hold, which will also cause nozzle blockage; after printing one solution, if the nozzle is not removed and cleaned, it cannot be used for printing another solution, causing solution pollution

Abstract

The invention provides an ultrasonic anti-blocking electric spraying nozzle device and a method, and belongs to the field of electric fluid spraying. The device comprises an injector, a piezoelectricelement, a conductive wire and a nozzle, wherein the conductive wire is arranged in the nozzle; one end of the conductive wire is close to the bottom outlet of the nozzle, and the other end extends out of the top end of the nozzles ans is externally connected with voltage; the top end of the nozzle communicates with the injector, and the outlet of the nozzle is connected with the piezoelectric element. The conductive wire is connected with the voltage to form an electric field, and electric spraying is performed; meanwhile, under the action of the piezoelectric element, resonance is formed, the solution in the nozzle is stirred; the nozzle blocking is improved; If the glass nozzle is blocked, the voltage with the corresponding frequency is applied to the piezoelectric element, so that thevibration of the piezoelectric element generates ultrasonic waves in the solution, and the nozzle dredging is realized. Through applying the invention, the solution is uniform and not layered during the spraying process; the glass nozzle is prevented from being blocked; the self-dredge of the nozzle can be realized after the nozzle is blocked, the work reliability is high, and the service life islong.

Description

technical field [0001] The invention relates to the field of electrohydrodynamic jet printing equipment, in particular to an ultrasonic anti-clogging electrojet printing nozzle device and method, which can improve nozzle clogging and realize self-unclogging of clogging. Background technique [0002] Electrohydrodynamic jet printing is to apply a voltage between the nozzle and the substrate to form an electric field, so that the solution forms a Taylor cone in the nozzle under the action of the electric field force, and then prints lines much smaller than the diameter of the nozzle. Since the diameter of the nozzle can be at the micron level, the pattern at the nanometer level can be realized by electrohydrodynamic jet printing, which makes it have broad application prospects in fine pattern printing. [0003] However, when electrohydrodynamic jet printing prints solutions with larger solute particles or volatile solvents, the nozzles will be clogged, resulting in inability t...
