what's the difference  between the electrostatic spray nozzle and base air spray nozzle?

electrostatic spray nozzle :

Disclosed is a system for electrostatic spraying of liquids, such as agricultural pesticides, paints and other liquids, which relies on a novel spray nozzle that combines pneumatic atomization and electrostatic induction charging to provide a stream of electrost
atically charged fine droplets. The nozzle uses a low voltage power supply, e.g. a 12 volt battery, electronically raises the voltage to a level in the range of several hundred to several thousand volts, and applies the high voltage to an annular induction electrode which is embedded in the spray nozzle. The high voltage components are inside the nozzle, which is made of an electrically insulating material to minimize the danger of shock and the possibility of mechanical damage to the high voltage components.

An airless spray nozzle which is capable of spraying paint of high viscosity as well as that of low viscosity while effectively preventing generation of tailing. A pair of stops formed between a substantially hemi-spherical depression of a front nozzle section and a through-hole of a rear nozzle section, a pair of main slants formed on the inner surface of the rear nozzle section defining the through-hole, a pair of first auxiliary slants and a pair of the second auxiliary slants each successively formed on the inner surface of the front nozzle section defining the depression cooperate to one another to positively spray paint of increased viscosity under a relatively low pressure without generating any tailing.
