At present, there are four types according to the principle of sprayer spray.
The Bernoulli principle says that in the same fluid, the flow rate is large and the pressure is small; the flow rate is small and the pressure is strong. Fluid will automatically flow from high pressure to low pressure. When passing through the trifurcated pipe, the low-speed flowing water flows to the high-speed flowing air. The water is torn into small droplets by high-speed air. (Imagine the water flowing from the faucet, which is just slow at the beginning, it is the water column; but then it gradually becomes larger and later becomes a drop.) When these tiny water droplets are sprayed out, they become a fog.
The principle of high-speed water breaking into small droplets after hitting obstacles
It uses the principle of pushing water into a thin tube to cause high-speed flow, and the high-speed flow of water hitting an obstacle and splitting into small droplets.
The situation is like opening the tap and blocking it with your finger. Domestic sprayers use this structure more often and at lower cost.
Centrifugal force throws liquid out of principle
High-speed rotating atomizer disc uses centrifugal force to throw liquid out and tear into small droplets
Similar to the situation when the umbrella rotates
Ultrasonic atomization principle
Vibration can cause “waves” on the surface of the water. The frequency of ultrasonic vibration is very high. Therefore, the wavelength of its “wave” is very small, so its “spray”—small water droplets are also small. These small water droplets become a fog.
