A sprayer is a device that turns water or other liquid into a mist and sprays it evenly onto other objects.

Conventional sprayers are mostly used on crops to achieve pesticial effects by evenly spraying the Pesticide solution onto the crop.


The principle of sprayer (4 Types):

1. High-speed water flowing into obstacles and then breaking into small water droplets

 It uses the principle that the water is pressed into the thin tube to cause high-speed water flow.High-speed movement of water is usually caused by compressed air. And the high-speed water flows into the small water droplets after hitting the obstacle. The situation is like blocking your faucet with your fingers. Household Most sprayers on the market are made according to this principle. The benefit of this structure is the low cost.


2. Centrifugal force to pull out the liquid

 The high-speed rotating atomizing disk uses centrifugal force to pry the liquid out and shred it into small droplets, similar to the case when the umbrella is rotated.

3. ultrasonic atomization

 Vibration can cause "wave" on the water surface. The vibration frequency of the ultrasonic wave is high enough, so its "wave" has a small wavelength and small water droplets.These small enough water droplets are fog in the air. The most typical sprayer made according to this principle is the humidifier.The humidifier allows the water molecules to enter the air more quickly through the ultrasonic waves, thereby bringing about humidification.


4. Bernoulli principle

(1) The Bernoulli principle says that the larger the liquid flow rate, the smaller the pressure; otherwise, the smaller the flow rate, the greater the pressure.The fluid will automatically flow from high pressure to low pressure. When passing through the trigeminal tube, the low-speed flowing water flows to the high-speed flowing air. The water is torn by a high-speed air into a small drop (assuming that the water flowing out of the faucet is slow at the beginning, it is a water column; but then the speed gradually increases and becomes a drop). These small water droplets are sprayed out and become fog.
