The nebulizer is an abbreviation for a nebulizer. A nebulizer is an instrument that uses a suction to make a liquid or other liquid into a mist and sprays it evenly onto other objects. It consists of a device that compresses air, a thin tube, and a nozzle.
In rural areas, sprayers are an indispensable and important tool for pest control.
At present, there are four types according to the principle of sprayer spray.
One is Bernoulli's principle. Bernoulli's 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. 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 second is the principle that the high-speed water breaks into small water droplets after hitting an obstacle. It uses the principle of pushing water into the thin tube to create high-speed water flow, and the high-speed water flowing into an obstacle and splitting into small water droplets. The situation is like opening the water tap. Block it with your fingers. Domestic sprayers use this structure more often and at lower cost.
The third is the principle that the centrifugal force throws the liquid away. The high-speed rotating atomizer disc uses centrifugal force to throw the liquid out and shred it into small droplets, similar to the situation when the umbrella rotates.
The fourth is the ultrasonic atomization principle. The vibration can cause “waves” on the surface of the water. The ultrasonic vibration frequency is very high. Therefore, the wavelength of its “wave” is very small, so its “spray”—small water droplets are also small. These small droplets become a fog.
