The principle of the sprayer

The principle of the sprayer (different types of sprayers have different principles):

(1) Bernoulli's principle. Bernoulli's principle states that in a fluid, the flow rate is large, the pressure is small; the flow rate is small, the pressure is strong. Fluid will automatically flow from high pressure to low pressure. When passing through the three-pronged pipe, the water flowing at a low speed flows to the air flowing at a high speed.

The water is torn into small drops by the high-speed air (imagine that the water flowing out of the faucet is slow at first, it is a water column; but then it becomes a drop after the speed gradually increases). When these small water droplets are sprayed out, they become mist.

(2) The principle that the high-speed water flow of the sprayer pump hits the obstacle and breaks into small water droplets. It uses the principle of pressing water into a thin tube to create a high-speed water flow, and the high-speed water flow breaks into small water droplets when it hits an obstacle. It's like turning on the faucet and plugging it with your fingers. This structure is often used in household sprayers, and the cost is low.

(3) The principle of centrifugal force throwing the liquid out. It is the high-speed rotating atomizing disc that uses centrifugal force to throw the liquid out and shreds it into small droplets, similar to the situation when the umbrella rotates.

(4) Principle of ultrasonic atomization. Vibration can cause "waves" on the water surface. The vibration frequency of ultrasonic waves is very high, so the wavelength of its "waves" is very small, so its "waves" are small, and the water droplets are also very small, and these small water droplets become fog.
