Nebulizer is the abbreviation of spray equipment. Nebulizer is a device that uses air suction to turn potions or other liquids into mist and spray them evenly on other objects. It is composed of compressed air devices, thin tubes, nozzles, etc. In rural areas, sprayers are an indispensable and important agricultural tool for controlling pests and diseases.
According to the principle of spraying, it is divided into four types.
Bernoulli's principle
Bernoulli's principle says 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.
The principle of high-speed water flow breaking into small water droplets after encountering obstacles
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.
Centrifugal force throws 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.
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" - small water droplets are also very small, and these small water droplets become fog. [1]
