Problems solved by technology
[0003] In the case of a non-conductive substrate, even if the substrate is connected to an external power source, the charge on the non-conductive substrate will be in a state of accumulation and cannot be evacuated, which will cause the electric field between the substrate and the print head to be inconsistent. Stable, unable to form a stable single jet, it is impossible to print

The invention discloses an ink-jet printing spraying pipe, an ink-jet printing spraying head and an ink-jet printer. The ink-jet printing spraying pipe is applied to the ink-jet printer. The ink-jet printing spraying pipe is characterized in that the ink-jet printing spraying head comprises an inner pipe and an outer pipe, an ink cavity capable of containing ink is formed in the inner pipe, the inner pipe is provided with an ink flowing opening communicating with the ink cavity, the outer pipe is arranged on the inner pipe in a sleeving manner, an isolating cavity is formed by the outer pipe and the inner pipe in an enclosure manner, the outer pipe is provided with an ink jetting opening corresponding to the ink flowing opening, an electric conducting layer is arranged on the portion, adjacent to the ink spraying opening, of the outer pipe, and the electric conducting layer is used for being connected with a positive pole or a negative pole of a power source. The ink-jet printing spraying pipe can achieve electric fluid ink-jet printing under the circumstance that a printing base material does not conduct electricity.
Description
technical field [0001] The invention relates to the technical field of printing, in particular to an inkjet printing nozzle, an inkjet printing nozzle and an inkjet printer. Background technique [0002] Electrofluid inkjet printing technology is a technology based on the principle of electrohydrodynamics to realize inkjet printing. When a conductive substrate is placed under the print nozzle, the print nozzle is connected to the positive pole of the power supply, and the conductive substrate is connected to the negative pole of the power supply. An electric field is established between the conductive substrates, and the effect of this electric field can induce the ink to deform at the nozzle of the print head. When the electric field force formed by the electric field is greater than the surface tension of the ink itself, a single jet will be formed, thereby achieving ink on the conductive substrate. print on . [0003] In the case of a non-conductive substrate, even if th...
