Problems solved by technology

Its disadvantages are mainly reflected in: limited control. Generally, the generation of electrostatic spraying requires a high electric field strength, while the collection of electrostatic droplets and the control of their movement and spatial distribution only require a low electric field strength, but the one-stage structure can only Use the same electric field to achieve these two functions with different requirements; it is difficult to miniaturize the device, especially in the array system; the applied voltage is too high, electrostatic shielding and insulating connection are difficult, and the cost is high ; a single electric field limits effective modulation of the spatial distribution of electrostatic droplets

Abstract

The invention provides a two-segment electric-field structure electrostatic spray system, array and using method, and belongs to the technical field of electrostatic spraying. The system comprises a nozzle (1) accessed to a first potential, a control electrode (2) accessed to a first potential, and a spray base (3) grounded or accessed to a third potential; the control electrode (2) and the nozzle (1) form an electrostatic liquid drop producing device, and the control electrode (2) and the spray base (3) form an electrostatic liquid drop collecting device. According to the two-segment electric-field structure electrostatic spray system, the control electrode is adopted to separate the producing device and collecting device of electrostatic liquid drops, a traditional one-segment electric field is separated into a two-segment electric field, a first segment of the electric field is utilized to produce the electrostatic liquid drops, and a second segment of the electric field is utilized to control movement and space distribution of the electrostatic liquid drops, so that security and flexibility are improved, space is saved, efficiency is improved, and the system is particularly adaptable to using in arrayed and miniaturized systems.

Description

[0001] Technical field [0002] The present invention involves a two -stage electrical field structure static spray system and array and usage. It belongs to the field of static spraying technology. Background technique [0003] Static spraying technology usually uses static electricity to spray the liquid from the nozzle to produce a small static spray droplet. Its size is usually ranging from a few microns to hundreds of microns.Its basic physical principles can generally be explained from the leakage medium model proposed by G. Taylor and J. R. Melcher.This technology has been widely used in industrial spray, fine weaving, micro -nano manufacturing, inkjet printing, biological testing and other fields. [0004] However, traditional static spraying technology usually integrates the static fluid droplet collection device and the electrostatic droplet droplet device, which constitutes a simple segment structure, so that the production of static fluid droplets and its spatial dist...
