Why can perfume atomizers be sprayed?

In the same fluid, the flow rate is large, the pressure is small; the flow rate is small, 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 low-speed flowing water is compressed, and then suddenly released through the micro-holes of the small nozzle (the principle is similar to the explosion of a bomb), and a relatively high-speed movement occurs between the liquid and the air, and the water is caused by the high-speed flow. Tear into small drops, one drop. These small water droplets will turn into the fog after being sprayed.

Some friends worry that the perfume will evaporate soon after it is put on, but this is not necessary.

The design of the perfume nozzle can effectively prevent volatilization because the contact surface between the liquid and the air in the nozzle is very small. The design of most nozzles can also prevent contact with air. The outer cap of the perfume is closed to surround the nozzle. At this time, the fluidity of the air around the nozzle is 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 problem of perfume passing through the nozzle and volatilizing.

Of course, if you unscrew the bottle cap, you can use it, like Cologne perfume, if you don't close the bottle cap, it will quickly evaporate in the air.
