Foam Pump

The foam pump bottle head has two important parts, the screen and the air chamber. The sieve is equivalent to a circular tool dipped in bubble water when blowing bubbles, and the air chamber is equivalent to an air blast device when blowing bubbles. When the pump head is pressed and then released, a low-pressure area is formed on the upper part of the foam dispenser pump head, and the liquid in the bottle is pumped to the upper part of the pump head, and the air is sucked into the air chamber at the same time. When pressing, the pressure of the air chamber increases, and the air and liquid are simultaneously squeezed to the screen (equivalent to blowing air to a ring tool dipped in bubble water), so that bubbles can be blown out. The smaller the sieve mesh, the finer the foam.
