Abstract
The liquid droplet spraying apparatus includes a chamber containing a fluid; a nozzle body having a nozzle for spraying the fluid in the chamber to one side of a material to be printed; an electrostatic spray module which is arranged in the vicinity of the chamber or the nozzle, and which forms an electrostatic field for the fluid contained in the chamber to provide a first spray force for spraying the fluid via the nozzle to form a liquid droplet; a physical spray module which is arranged in the chamber and opposite the nozzle, and which provides a second spray force for assisting the first spray force when the first spray force is generated; and a control unit for controlling the electrostatic spray module and the physical spray module such that the first spray force and the second spray force can be provided in a specific pattern.The liquid droplet spraying apparatus includes a chamber containing a fluid; a nozzle body having a nozzle for spraying the fluid in the chamber to one side of a material to be printed; an electrostatic spray module which is arranged in the vicinity of the chamber or the nozzle, and which forms an electrostatic field for the fluid contained in the chamb…
