According to the principle of sprayer spray, it is divided into four types.
The Bernoulli principle says that in the fluid, the flow rate is large and the pressure is small; the flow rate is small and the pressure is strong. The fluid will automatically flow from high pressure to low pressure. When passing through the trigeminal tube, the low-speed flowing water flows to the high-speed flowing air. The water is torn by a high-speed air into a small drop (assuming that the water flowing out of the faucet is slow at the beginning, it is a water column; but then the speed gradually increases and becomes a drop). When these small water droplets are sprayed out, they become fog.
The principle of high-speed water flowing into obstacles and then breaking into small water droplets
It uses the principle that the water is pressed into the thin tube to cause high-speed water flow, and the high-speed water flow breaks into obstacles and then breaks into small water droplets. The situation is like plugging the faucet and blocking it with your fingers. Household sprayers use this structure and are low in cost.
Centrifugal force to pull out the liquid
The atomizing disk that rotates at a high speed uses centrifugal force to pry the liquid out and tear it into small droplets, similar to the case when the umbrella is rotated.
Principle of ultrasonic atomization
Vibration can cause "spray" on the water surface. The vibration frequency of the ultrasonic wave is very high, so its "wave" has a small wavelength, so its "spray" - small water droplets are also small, and these small water droplets become fog.
