As the darling of the fashion industry, perfume has always been very popular, so today we will talk about the structure and working principle of the perfume atomizer.
1. Air flow
All atomizers work according to the principles of airflow and suction. When the horizontal air passes over the vertical pipe, it will cause the air and liquid in the vertical pipe to be pulled upward. A classic atomizer uses a squeeze bulb to store a large amount of air, and when squeezed, the air will move quickly on the feeding tube. There are two check valves at both ends of the bulb. When the light bulb is pressed, the valve to the bottle is forcibly opened under the action of air pressure, and the valve to the outside is closed. After releasing the bulb, the rubber inside restores it to its original shape, closing the valve to the pipe, and opening the valve to the outside so that air can fill the bulb.
2. Oil storage tank and feed pipe
The perfume is placed in the body of the perfume bottle or "container". The vertical feeding tube is partially immersed in the liquid storage tank and connected to the cap of the bottle. The cap of the bottle is also equipped with a tube connecting the squeeze ball and the nozzle. The air draws the liquid up into the feed tube through the created vacuum and pushes it out through the nozzle. When the airflow stops, a small amount of liquid remains in the test tube, and due to the cohesiveness of the liquid, once the bulb is squeezed again, it will act as another mechanism to pull the perfume into the test tube.
The nozzle is the end of a horizontal tube, usually made of metal or plastic. When air and liquid perfume pass through the nozzle, it will cause the perfume to break down into droplets and mix with the air. The restriction at the end of the nozzle is called a "Venturi", which accelerates the speed of the air and liquid mixture, causing the liquid to decompose and dispersing the air widely. Depending on the intensity of the squeeze bulb, the amount of liquid and the distance it spreads will change.
"Atomization" does not mean decomposing into its constituent atoms, but decomposing large objects into small discrete objects, usually suspended in another medium. In this case, the liquid fragrance is a mixture of oil, alcohol, water and dye. When the air flow draws some liquid from the storage tank and mixes it with the air flow, the liquid breaks down into droplets suspended in the air. The proportions of oil, alcohol, water and dye in each droplet are the same.
