Abstract

The invention discloses a droplet jetting device and method, and belongs to the field of ink-jet printing. The droplet jetting device comprises a cavitation generator, a cavity, a cover plate and a nozzle. The cavitation generator is arranged on the cover plate, a liquid injection port is formed in the bottom of the cavity, and the cover plate and the nozzle are arranged at the upper end of the cavity. According to the device, under a combined action of the cavitation generator and a power supply controller, droplet jetting and conveying are completed through a liquid level breaking jet flow caused by cavitation behaviors near a liquid level, droplet conveying in a liquid level breaking form is adopted, the droplet jetting device is simple, compact, safe and reliable in structure, under the combined action of the cavitation generator and the power supply controller, the droplet jetting and conveying are completed through the liquid level breaking jet flow caused by the cavitation behaviors near the liquid level, no heating device, mechanical structure and other components exist, and the sealing performance and stability of the device are guaranteed. Therefore, the device has the advantages of simple structure, convenience in processing, low maintenance cost, high efficiency, energy conservation and the like.

Description
