Important functional parameters and working principle of lotion pump
Jun 28, 2023
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 the push-type lotion pump. It uses the principle of atmospheric pressure balance to pop out the lotion in the bottle by pressing, and can also replenish the outside atmosphere into the bottle. A liquid dispensing tool, and then I will talk to you about the working principle of the lotion pump and its important functions and parameters.
When purchasing a product that includes a recyclable lotion pump, we should know that during the pressing process, its head needs to be connected through the dare to drive the piston through the action of the compression spring for use. During the process of compressing the spring, the lotion pump The outer wall of the piston tends to be fully opened through 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 in the inside through multiple pressing, and then press the head with the hand, through the action of the piston head piston connecting rod and the compression spring, the internal air is discharged, and at this time loosen it with the hand Open the pressure head of the lotion pump, at this time the spring will lose the pressure effect and move downward again, and 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 liquid storage gun inside it 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 chamber through the action of the straw, and the liquid will be absorbed by pressing the head of the lotion pump multiple 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, which is the working principle of the lotion pump.
Everyone knows that the pump output of lotion pump is often a very important parameter, which is related to the error and sealing of parts of lotion pump. Generally speaking, the number of times of air pressure and the capacity of the pressed liquid are an important parameter of user experience, and it is also a very important standard for manufacturers to test lotion pumps in the production process. I hope that through this article, everyone can have a better understanding of lotion pumps. Have a basic understanding of how pumps work.
