Abstract
The invention relates to the technical field of inkjet printing, and in particular to a spray head, an inkjet printing device, and an inkjet printing system and method to solve the problem that a liquid metal printing technique in the prior art has a narrow application range, is not conducive to printing a variety of metals, and is likely to clog the spray head after printing. An embodiment of thepresent invention provides a spray head, which includes a nozzle, a spray cavity connected to the nozzle, and a fluid driving component connected to the spray cavity. The spray cavity is provided with a fluid inlet. The fluid driving component is configured to driving a fluid flowing into the spray cavity toward the nozzle side so as to eject the fluid out of the nozzle. The spray cavity and thenozzle are both surrounded by a first electromagnetic heating coil. The embodiment of the present invention is used for directly forming a circuit by printing.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a nozzle, an inkjet printing device, an inkjet printing system and a method. Background technique [0002] With the continuous advancement of printed electronics technology, conductive pulse voltage signal bodies represented by liquid metals have emerged, making direct writing, printing and other circuit direct printing technologies possible.
