The invention relates to the field of micro-nano jet printing processes, in particular to a bionic structure spray head capable of jet printing high-acceleration jet flow and a process of the bionic structure spray head. The feeding mechanism is arranged above the bore mechanism and used for storing the printing ink and conveying the printing ink to the bore mechanism; the gill cover mechanisms are arranged on the two sides of the feeding mechanism and used for conducting extrusion driving on the printing ink. And the printing substrate is used for collecting the array ink dots output by the bore mechanism. The method has the advantages that by combining the advantages of existing piezoelectric jet printing and micro-nano electrohydrodynamic jet printing, the method can be used for printing dots with excellent jet printing morphology and smaller scale level, and meanwhile, the method is suitable for jet printing of materials with different viscosities.
