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 emulsion pump. Emulsion pump is also known as the press type emulsion pump, it is a kind of use of the principle of atmospheric pressure balance, so as to press the way of the bottle of emulsion out, and can also be added to the outside atmosphere into the bottle of a liquid distribution tool, then Xiaobian to talk about the working principle of the emulsion pump and its important functions and parameters.

When purchasing products including emulsion pump, we should know that in the process of pressing, its head needs to drive the piston through its connection to the action of compression spring for use, in the process of compression spring, the outer wall of the piston pump often through the friction of the inner wall, so that the piston is fully opened, and the discharge hole of the piston head will appear liquid, As the piston moves down, it pushes the air inside out of the piston head.

We can make the air inside completely discharged by pressing several times, and then press the head by hand, through the piston head piston connecting rod and compression spring, so as to exhaust the internal air, at this time, loosen the pressure head of the emulsion pump by hand, at this time the spring will lose the effect of pressure, and move down again, At this time, the piston moves down through the friction of the inner wall so that the discharge hole is closed. At this time, the internal liquid storage gun will form a hollow state, 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 into the liquid storage chamber by pressing the head of the emulsion pump several 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 emulsion pump is pressed again, the liquid can be directly ejected from the mouth through the discharge hole, this is the working principle of the emulsion pump.

As we all know, the pump output of the emulsion pump is often a very important parameter, which is related to the error and sealing of the parts of the emulsion pump. In general, the number of air pressure and the capacity of the liquid pressed out are an important parameter of the user experience, but also a very important standard for the manufacturer to test the emulsion pump in the production process. I hope that through this article, we can have a basic understanding of the working principle of the emulsion pump.
