Principle of the atomizer sprayer

There are four principles of spraying:

One uses Bernoulli's principle. Bernoulli's principle says that in the same fluid, the higher the flow rate, the lower the pressure; the lower the flow, the higher the pressure. The fluid will automatically flow from high pressure to low pressure. Passing through the trifurcated tube (the specific picture cannot be drawn, I will figure it out myself), the low-speed flowing water flows towards the high-speed flowing air. Water is torn into small droplets by air at high speed (imagine water flowing from the faucet, it is first a column of water at slow speed; but then it becomes a droplet once as the speed gradually increases). These small water droplets turn into mist after being sprayed.

The second method involves squeezing water into a thin tube to cause water to flow at high speedsse. The high-speed water flow breaks into small water droplets after hitting obstacles. The situation is as if you turned on the faucet and then blocked it with your fingers. Home sprayers often use this structure and are inexpensive.

The third method is to charge the water (water is a dielectric) and use the same charges to repel each other to split the water into droplets. The water droplets used in this method are very small. The same principle is used to paint cars.

The fourth type is ultrasonic atomization. Vibration can cause “spray” 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" - the small water droplets are also very small, and these small. water droplets turn into mist. LThroat sprays used to treat respiratory illnesses in hospitals use ultrasonic atomization.
