The first is to charge water (which is a dielectric) and divide it into droplets by repulsion of the same charge. The droplets in this method are very small. The same principle is used to paint cars. The second is ultrasonic atomization. The vibration can cause & quot;spray & quot; on the water surface. The vibration frequency of the ultrasonic wave is very high, so its wave length is very small. Therefore, its & quot;spray & quot; is like a small drop of water. These drops become fog. The respiratory disease in the hospital uses an ultrasonic nebulizer.
