Let us first clarify the nature of blistering. Foaming is actually the mixing of gas and liquid, and a single bubble is the smallest form of mixing. Everyone must have blown bubbles when they were young, or at least saw people blow bubbles.

A tool with a closed circle is often used when blowing bubbles. The function of this circle is to spread the liquid in the space into a film, so that people can blow air into the film to stretch it. Relying on the tension of the liquid surface, the stretched film is spontaneously tightened and closed to form bubbles.

So, with the same blowing ability (for example, people blowing), how can we create more bubbles? In other words, how to improve the efficiency of air and liquid mixing? The answer is simple-increase the number of circles. Ever since, there has been a bubble blowing tool with multiple closed circles.

The same is true for the foaming pump head. It is not difficult to find that there are a large number of net-like structures on the shower flower, and the sponge also has a similar porous structure. These structures are like countless bubbles blowing circles, which can efficiently mix the liquid and air in them to form delicate bubbles.

Finally, let us go back to the foaming pump head. The secret of mixing air and liquid quickly is also a mesh structure. If you open the hand-pressure pump head of the foaming pump head, you will see that there is a screen on the way the liquid must pass.

Unlike ordinary pump heads, the foaming pump head has an enlarged air chamber in the throat. When it is released after the first press, a low pressure is formed in the upper part of the pump head, so that the liquid is pumped to the upper part of the pump head, and air enters the air chamber at the same time. During the second press, the air chamber is pressurized to pump the liquid and air into the screen on the pipe at the same time, so that bubbles will be blown out. The smaller the screen, the smaller the bubble blown out, and the finer the bubble.
