As of today, we have cooperated with thousands of customers, large and small, and most of the customers' needs are cosmetic sprayers. The two parties are used to the transaction process of one-handed payment and one-handed delivery. But yesterday, a new customer who had just cooperated was confused by the sales question. The customer asked: What is the spray principle of a cosmetic sprayer? It's really not a good explanation to ask this question suddenly. Today, let's analyze systematically what is the principle of the spray of cosmetic sprayer?
Strictly speaking, there are 4 principles of cosmetic sprayer:
1. Bernoulli principle:
Bernoulli's principle says that in the same fluid, the flow velocity is large, the pressure is small; the flow velocity is small, the pressure is strong. The fluid will automatically flow from high pressure to low pressure. When passing through the three-pronged pipe, the low-speed flowing water flows to the high-speed flowing air. The water is torn into droplets by the high-speed air (Imagine that the water flowing out of the faucet has a slow speed at first, which is a water column; but then the speed gradually increases and becomes drop by drop). These small water droplets become fog after spraying out.
2. The principle that the high-speed water flow breaks into small water droplets after encountering obstacles:
It uses the principle of pressing water into a thin tube to cause high-speed water flow, which breaks into small water droplets when it hits an obstacle. The situation is like turning on the faucet and blocking it with your fingers. Household sprayers often use this structure, and the cost is low.
3. The principle of centrifugal force to throw the liquid out
It is a high-speed rotating atomization disk that uses centrifugal force to throw the liquid out, and shred it into small droplets, similar to the situation when an umbrella rotates
4. Principle of ultrasonic atomization:
Vibration can cause "sprays" on the water surface. The vibration frequency of ultrasonic waves is very high, so the wavelength of its "waves" is very small, so its "sprays"-small water droplets are also very small, and these small water droplets become fog.
Generally, the cosmetic sprayer used by everyone basically adopts the Bernoulli principle. It is made using the principle of high flow rate and low pressure, allowing air to flow out quickly from the small hole. The pressure near the small hole is small. The pressure of the air above the liquid level in the container is strong, and the liquid rises up along the thin tube below the small hole. After flowing out from the upper mouth of the thin tube, it is sprayed into mist by the impact of the airflow. In addition, the carburetor of a gasoline engine has the same principle as an atomizer.
how about it? Unexpectedly, there is so much knowledge in the little cosmetic sprayer.
