Learn some Cosmetic Sprayer Pump knowledge:

What is an atomizing nozzle?

The atomizer nozzle is the component that produces the liquid mist spray.

When the airflow is injected through the top of the vertical tube, it creates a venturi, which can be explained by Bernoulli's principle.

The pressure differential forces the liquid from the chamber up the tube and into the dynamic air, where it is dispersed into small droplets and carried away by air.

What is a nozzle and do different nozzles produce different forms of mist?

A nozzle is a device that ensures the dispersion of a liquid into a spray. Yes, different nozzles produce different forms.

The hole in the nozzle is right against the end of the fluid line to prevent disturbance of the outgoing water flow.

But when it's set to spray, the nozzle inserts a small chamber between the bottle and the hole in the nozzle.

Putting all the information together to answer - how does mist spray form mist?

The pump forces the liquid through a nozzle that disrupts the flow of the liquid, turning it into a fine mist.

Nebulizers have smaller diameter orifices, resulting in higher pressure in the fluid.

Higher pressure results in higher velocity and inertia of the fluid.

All in all, the main manufacturing principle of the spray bottle is to form a high-pressure system inside the bottle, and the liquid inside the bottle is sprayed out like tiny water droplets. This bottle is called a spray bottle because of its similar effect and form to natural mist.
