According to the principles of the principles of spray sprayer is divided into four. Bernoulli's principle Bernoulli's principle says that in a fluid, the flow rate is high and the pressure is low; the flow rate is low and the pressure is high. The fluid will flow automatically from high to low pressure. As it passes through the Trident, the slow-moving water flows towards the fast-moving air. Water is pulled apart by high-speed air in small drops (imagine the water from the Faucet, at first slow, is the water column; but then gradually increasing the speed into a drop by drop) . These little drops of water squirt out and become fog.
