1. Principle of electric sprayer:

The principle is that in the same fluid, the flow velocity is large and the pressure is small; the flow velocity is small and the pressure is strong. The fluid will automatically flow from high pressure to low pressure. When passing through the trident, the water flowing at low speed flows to the air flowing at high speed. The water was torn into small droplets by high-speed air (Imagine that the water flowing out of the faucet was initially slow and was a column of water; but then it gradually became a drop after a speed increase). These small drops of water sprayed into fog.

2. The principle of high-speed water flow breaking into obstacles after encountering obstacles:

The principle is to press water into a thin tube to cause high-speed water flow, and the high-speed water flow breaks into small droplets after hitting obstacles. It looks like the faucet is opened and blocked with fingers. Household sprayers often use this structure, and the cost is low.

3. The principle of centrifugal force throwing liquid out:

It is a high-speed rotating atomizing disc that uses centrifugal force to throw out liquid and shred 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. The frequency of ultrasonic vibration is very high, so its "waves" have a very small wavelength, so its "waves"-small water droplets are also very small, and these small water droplets become fog.
