Bernoulli principle

Bernoulli's principle says that in the fluid, the velocity is high, the pressure is small; the velocity is small, the pressure is high. The fluid will automatically flow from high pressure to low pressure. When passing through the Trident, the low-speed flow of water flows to the high-speed flow of air. Water is torn into small drops by high-speed air (imagine that the water flowing out of the faucet is slow at first, which is a water column; but then it gradually increases and becomes a drop by drop). These little drops of water spray out and become fog.

The principle of high-speed water splitting into small water droplets after encountering obstacles

The principle of high-speed water flow caused by the water pressure into the thin pipe is used, and the high-speed water flow will crack into small water drops after encountering obstacles. It's like turning on the tap and plugging it with your fingers. The household sprayer uses this structure and costs much.

Principle of centrifugal force throwing liquid out

It is a high-speed rotating atomization disk, which uses centrifugal force to throw the liquid out and tear it into small droplets, similar to the situation when the umbrella rotates.

Principle of ultrasonic atomization

Vibration can cause "spray" on the water surface. The vibration frequency of ultrasonic wave is very high, so its "wave" wavelength is very small, so its "spray" - small water droplets are also very small, these small water droplets become fog.
