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 so that the lotion in the bottle is popped out by pressing, and the external atmosphere can also be replenished into the bottle. A liquid dispensing tool, then AOBANG Sprayer Pumps Manufacturers will talk to you about the working principle of the lotion pump and its important functions and parameters.

　　When buying a product containing a lotion pump, we should know that in the process of pressing, its head needs to be connected through its connection to drive the piston to use the compression spring. During the process of compressing the spring, the lotion pump The outer wall of the piston tends to be fully opened by the friction of the inner cavity wall, and liquid will appear in the discharge hole of the piston head. When the piston moves downward, the air inside will be discharged from the piston head. go.

　　We can completely discharge the air inside by pressing several times, and then press the head by hand, through the action of the piston head piston connecting rod and the compression spring, to discharge the internal air, then loosen it by hand. Open the pressure head of the lotion pump. At this time, the spring will lose its pressure and move downward again. At this time, the piston moves downward through the friction of the inner wall, so that the discharge hole is closed. At this time, the internal liquid storage gun is A hollow state will be formed, and the ball valve will be lifted. At this time, the liquid in the bottle will be sucked into the liquid storage chamber through the action of the straw, and the head of the lotion pump will be pressed many times to absorb the liquid many times. The liquid can be stored in the cylinder until there is no gap, and at this time, as long as the head of the lotion pump is pressed again, the liquid can be sprayed directly from the mouth through the discharge hole. This is the working principle of the lotion pump.

　　We all know that the pump output of the 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 air pressures and the volume of the pressed liquid are both important parameters for the user experience, and also a very important standard for manufacturers to inspect the lotion pump during the production process. I hope that through this article, everyone can understand the lotion pump and Have a basic understanding of how pumps work.
