With the gradual improvement of people's living conditions, the use of many household items has become more and more convenient, including the application of lotion pumps. The lotion pump is also called a push-type lotion pump. It uses the principle of atmospheric pressure balance to pop out the lotion in the bottle by pressing, and it can also supplement the outside atmosphere into the bottle. This is a liquid distribution tool. Next, the editor will talk to you about the working principle of the lotion pump and its important functions and parameters.

When buying a product that contains a lotion pump, we should know that in the process of pressing, its head needs to be connected through its dare to drive the piston to use the compression spring. In the process of compressing the spring, the lotion pump The outer wall of the piston often uses the friction of the inner cavity wall to make the piston fully open, and liquid will appear in the discharge hole of the piston head. When the piston moves down, the air inside will be discharged from the piston head. go.

We can completely exhaust the air inside by pressing repeatedly, and then press the head with our hands, through the action of the piston head piston connecting rod and the compression spring, so as to exhaust the internal air, then loosen it by hand. When the pressure head of the lotion pump is opened, the spring will lose the effect of pressure and move downward again. At this time, the piston moves downward by rubbing the inner wall so that the discharge hole is closed. At this time, the liquid storage gun inside is closed. A hollow state will be formed, and the ball valve will be lifted up. At this time, the liquid in the bottle will be sucked into the liquid storage cavity through the action of the straw. By pressing the head of the lotion pump several times, it will absorb the liquid several times. The liquid can be stored in the cylinder until there are no gaps. At this time, as long as the head of the lotion pump is pressed again, the liquid can be sprayed directly from the nozzle through the discharge hole. This is the working principle of the lotion pump.

Everyone knows that the pumping volume of a lotion pump is often a very important parameter, which is related to the error and sealing of the parts of the lotion pump. Generally speaking, the number of times of air pressure and the volume of liquid pressed are both an important parameter of user experience. It is also a very important standard for manufacturers to inspect emulsion pumps during the production process. I hope that through this article, everyone will be able to Have a basic understanding of the working principle of the pump.
