A foam pump uses air to press the contents out to form foam. Commonly used in the packaging of hand sanitizers, detergents, and other products.

    Before the invention of the foam pump, the foam was usually sprayed by aerosol-type products, that is, the foam was formed by expanding the spray with liquefied gas, or a foaming agent was used after spraying a colloid.

    From the internal structure of the product, the acupressure foam pump is mainly divided into the following five parts:

    Actuating part: The function is to transmit the force to other parts inside the product through the pressure head and realize the pressure rebound cycle and drainage process of the foam pump through the spring. It can be divided into different shapes and colors as needed according to the head shape design (as shown in the picture above).

    Liquid storage chamber: the function is to press the machine head down during the extrusion process of the liquid storage room, and the liquid storage room will suck the liquid bottle according to the rebound of the machine head; in addition, the built-in spring of the liquid storage room plays a rebounding role.

   Air Reservoir: Similar to the liquid reservoir, except that air is sucked in and squeezed out of the air reservoir.

   Pipeline part: the connection between the liquid in the bottle and the whole pump, the channel for the liquid to enter the liquid storage chamber, to ensure that the liquid in the bottle can be sprayed quickly and reduce the residual amount of liquid.

    Gas-liquid mixing chamber: When the pressure head is pressed down, the liquid in the liquid storage chamber, the liquid, and air in the gas storage chamber are fully mixed and pressurized in the gas-liquid mixing chamber, and fine foam is formed through the dense foam. The mesh of the airflow mixing chamber.

    The working principle of the foam pump seen on the market is basically the same. Compared with the traditional pump, the structure of the whole acupressure foam pump is more complicated and has an air storage chamber. The pump is the core part of the whole product, it determines the liquid volume, foaming effect, and stability.
