Trigger sprayeris referred to Aerosol spray equipment . "Fog" is
actually water droplets. Currently, in accordance with the
principles of aerosol spray is divided into four types. Bernoulli's
Principle Bernoulli's principle says that in the same fluid, the
velocity, pressure is small; flow rate is small, strong pressure.
High-pressure fluid may flow automatically from the low.Tube
through the trigeminal, the flow of water to high-speed low-speed
flow of air.Water is a small high-speed air ripped a small drop
(imagine the water faucet, slow beginning, is the water column; but
then the speed increases, it becomes a drop by drop).
These small water droplets emitted into the fog after. Obstacles
encountered after high-speed flow the principle of splitting into
small water droplets The second use is to create high pressure
water into the small tube, obstacles encountered, after high-speed
flow the principle of splitting into smaller droplets.
Situation like the plug with your fingers to open the
tap.Multi-purpose household sprayer of this structure and low cost.
Principle of centrifugal force the liquid thrown The third is a
high-speed rotating disk atomization of liquid using centrifugal
force to throw to, pieces for small droplets The situation is
similar to an umbrella rotation Principles of ultrasonic
atomization The fourth is the principle of ultrasonic atomization.
Vibration can cause the water "spray", the ultrasonic vibration
frequency is very high, so it's "waves" of the wavelength is very
small, so it's "waves" - a very small water droplets, these
droplets become fog.
