Why Can Perfume Sprayers Spray?

Why can perfume sprayers spray?
In the same fluid, the flow rate is large and the pressure is small; the flow rate is small and the pressure is large. The fluid will flow from high pressure to low pressure.
The nozzle itself has a mechanical structure that can compress the liquid to generate high pressure. When the liquid passes through the perfume nozzle, the water flowing at a low speed is compressed, and then suddenly released through the micropores of the small nozzle (the principle is similar to a bomb explosion), and a relatively high-speed movement occurs between the liquid and the air. The water is torn into small droplets due to the high-speed flow. A drop. These small water droplets will become mist after being sprayed out.
Some friends are worried that the perfume will evaporate quickly after it is put out, but this is not necessary.
The design of the perfume nozzle can effectively prevent volatilization because the contact surface between the liquid in the nozzle and the air is small. Most nozzles are also designed to prevent contact with the air. The outer cover of the perfume is closed to surround the nozzle. At this time, the air flow around the nozzle will be reduced, so the volatilization is very low. After calculation, only a small part of the nozzle hole of the nozzle device will evaporate, so there is no need to worry too much about the perfume passing through the nozzle and volatilization.
Of course, if you unscrew the cap and use it, like cologne, if you don't close the cap, it will evaporate quickly in the air.
