There are four working principles, as follows:
1. Bernoulli principle:
Bernoulli's principle says that in the same fluid, the flow rate is large, but 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 pipe, the low-speed flowing water flows to the high-speed flowing air. The water is torn into droplets by high-speed air (Imagine that the water flowing out of the faucet has a slow speed at first, which is a column of water; but then the speed gradually increases and then becomes drop by drop). These small water droplets become fog after spraying out.
2. The principle that the high-speed water flow breaks into small water droplets after hitting an obstacle:
It uses the principle of pressing water into a thin tube to cause a high-speed water flow, and the high-speed water flow breaks into small water droplets when it hits an obstacle. The situation is like turning on the faucet and blocking it with your fingers. Household sprayers often use this structure, and the cost is low.
3. The principle of the centrifugal force to throw the liquid out:
It is a high-speed rotating atomization disk that uses centrifugal force to throw the liquid out and shred it into small droplets, similar to the situation when an umbrella rotates.
4. Principle of ultrasonic atomization:
Vibration can cause "sprays" on the water surface. The vibration frequency of ultrasonic waves is very high, so the wavelength of its "waves" is very small, so its "sprays"—small water droplets are also very small, and these small water droplets become fog.
It didn’t come out after a period of time. The air pressure should be too low. Just adjust the air pressure.
