Principle of spray

1. Bernoulli's principle:
The Bernoulli principle states that in a fluid, the flow velocity is high and the pressure is low; Low flow rate, high pressure. The fluid will automatically flow from high pressure to low pressure. When passing through a three-way pipe, the low-speed flowing water flows towards the high-speed flowing air. Water is torn into small droplets by high-speed air (imagine the water flowing out of the faucet, initially slow, as a column of water). These small water droplets spray out and become mist.
2. The principle of high-speed water flow breaking into small water droplets when encountering obstacles
It uses the principle of injecting water pressure into a thin tube to create high-speed water flow, which breaks into small water droplets when it encounters obstacles. The situation is like turning on the faucet and blocking it with your fingers. This structure is commonly used in household spray, and the cost is low.
3. The principle of centrifugal force throwing liquid out
It is a high-speed rotating atomization disk that uses centrifugal force to throw liquid out, tearing it into small droplets, similar to the situation when an umbrella rotates.
4. Principle of ultrasonic atomization
Vibration can cause "waves" on the water surface, and the vibration frequency of ultrasound is very high, so the wavelength of its "waves" is very small, so its "waves" - small water droplets are also very small, and these small water droplets become fog.
