Abstract

The invention belongs to the field of electrofluid jet printing spray-head correlation technique, and discloses an airflow auxiliary electric jet printing spray-head integrated with a grounding electrode. The airflow auxiliary electric jet printing spray-head comprises a liquid inlet cylinder, a gas hood, a metal needle head, an electric lead, an electrode cover and an annular electrode. The liquid inlet cylinder is connected to the gas hood and is partially held in the gas hood; two ends of the gas hood connected with the liquid inlet cylinder and the electrode cover; one end of the metal needle head and the liquid inlet cylinder form threaded connection, and the other end of the metal needle head penetrates through the gas hood so as to stretch into the electrode cover; one end of the electric lead is connected to a high voltage power supply, and the other end of the electric lead penetrates through the liquid inlet cylinder so as to be connected to the metal needle head; the annular electrode is embedded into the electrode cover; and the grounding electrode is integrated into the airflow auxiliary electric jet printing spray-head through grounding. The airflow auxiliary electric jet printing spray-head provided by the invention is provided with the grounding electrode through arranging the annular electrode, so that a collecting substrate has no need to be grounded, and the application range and the flexibility are improved.

Description

technical field [0001] The invention belongs to the related technical field of electrofluid jet printing nozzles, and more specifically relates to an airflow assisted electrojet printing nozzle integrated with a ground electrode. Background technique [0002] Inkjet printing technology is an additive manufacturing method that can be well applied in the field of flexible manufacturing. Initially, inkjet printing technology was developed in graphic arts; now, inkjet printing technology has been well improved and has a wide range of applications in electronics, optics, bioengineering, etc. Inkjet printing equipment has been widely used in recent years due to its advantages of material saving, environmental friendliness, and simple operation. Traditional inkjet printing technology has disadvantages such as low printing resolution, droplet size limited by nozzle diameter, easy nozzle clogging, and complicated nozzle manufacturing process. Compared with traditional inkjet printi...
