How the lotion pump works?

Most of the accessories of the pump head are mainly made of plastic materials such as PE, PP, and LDPE, and are molded by injection molding. Among them, glass beads, springs, gaskets and other accessories are generally purchased outside. The main components of the pump head can be applied to electroplating, anodized aluminum cover, spraying, injection molding and other methods. Both the surface of the pump head and the surface of the braces can be printed with graphics and text, and can be processed by printing processes such as bronzing/silver printing, silk screen printing, and pad printing.

2. Working principle

Manually press down the pressure handle, the volume in the spring chamber decreases, the pressure rises, the liquid enters the nozzle chamber through the hole of the valve core, and then sprays out the liquid through the nozzle, at this time release the pressure handle, the pressure in the spring chamber The volume increases, forming a negative pressure, the ball opens under the negative pressure, the liquid in the bottle enters the spring chamber, at this time there is a certain amount of liquid in the valve body, when the handle is pressed again, the liquid stored in the valve body will be released Rush upwards and spray out through the nozzle;
