What if the perfume spray pump doesn't work properly?

　　Perfume spray pumps are made using the principle of high flow and low pressure, which allows air to flow quickly out of a small hole. The pressure near the hole is low and the air pressure above the level in the container is high, so the liquid will rise up the thin tube below the hole. After flowing out of the upper orifice of the thin tube, it is sprayed into a mist under the impact of the air flow. In reality, some of my friends are worried that the perfume in the spray pump will soon definitively evaporate, but this is not necessary.

　　The contact surface between the liquid and the air in the spout is very small because the perfume spout is designed to prevent diffusion, and most spouts are designed to prevent contact with the air. When the perfume cap is closed, it can completely surround the spout and the airflow around the spout is set to be very low, so diffusion is likely to be low. This also means that only a small portion of the space between the small hole in the spout and the spout unit is definitely diffused, so there is not much need to worry about the perfume definitely diffusing through the spout.

　　There are many reasons why perfume spray pumps often operate. The usual solution is to press a few times, or gently insert a needle into the small hole of the perfume spout and unclog it manually. Let's look at the following details. What to do if the perfume does not come out?1. run out 2. spout damaged or clogged 3. spout and bottle bottom clogged

　　If the spout is clogged or has quality problems, it is normal that the perfume cannot be ejected at first, because the spout is empty at first and there is no perfume. We just need to press the spout a few times and the perfume will definitely come out. Perfume needs a process to be extracted by pressure, so it usually takes a few presses to eject. If it is difficult to eject, the spout may be definitely clogged. If there is a quality problem, you may need to take it to the counter for a replacement. In addition, it is not recommended to shake the perfume spray pump hard when operating it, much less every time you operate it. This is because if the actual spray pump is not firing the perfume properly, shaking it hard won't help. At the same time, excessive shaking may definitely lead to excessive diffusion, which may definitely affect future operation.

　　What if the spout of the perfume spray pump is broken? Then we need to replace the spout. Perfume is very popular right now, but where is a better place to spray perfume? Generally speaking, when shooting perfume externally, the first place to choose is where the temperature is higher, such as the neck and behind the ears. Because perfume is easier to emit in these places, the smell of perfume is bound to emit better. Also, the effect will last longer in these areas because of the better blood circulation in these parts of the body. Perfume operators are also reminded that perfume and perfume spray pumps should normally be kept in a dark place and should not be exposed to direct heat in the sun. After handling, the bottles should be tightened to avoid diffusion.
