How Lotion Pumps Work

Update:14 Oct 2022

Most of the parts of the Lotion Pump are mainly made of PE, PP, LDPE, and other plastic materials, which are molded by injection molding. Among them, glass beads, springs, gaskets, and other accessories are generally purchased from outside. The main components of the pump head can be applied to electroplating, anodized aluminum cover, spraying, injection molding color, etc. Graphics and texts can be printed on the nozzle surface of the pump head and the surface of the braces and can be processed by printing processes such as bronzing/silver, silk screen printing, and pad printing.

Its working principle: manually press the dynamic pressure handle downward, the volume in the spring cavity decreases, the pressure increases, the liquid enters the nozzle cavity through the hole of the valve core, and then the liquid is sprayed out through the nozzle, and then the pressure handle is released. , the volume in the spring cavity increases, forming a negative pressure, the ball is opened under the action of negative pressure, and the liquid in the bottle enters the spring cavity. At this time, there is a certain amount of liquid in the valve body, which is stored in the valve body when the handle is pressed again. The liquid in the liquid will rush upward and spray out through the nozzle;
