The shallow explanation of the foam pump in the previous issue, I believe everyone has a certain understanding of the foam pump.So today I will take you to talk about the internal structure of the foam pump.

A foam pump is used to suck the liquid in the container and make the liquid spray foam from the nozzle.The casing is composed of a pump head, a screw cap and a cylinder, and also includes an air valve and a filter screen support. It is characterized in that a spray hole is arranged in the pump head, and the air valve is arranged below the spray hole, between the spray hole and the air valve. A liquid spray channel is formed, and the filter screen support is arranged in the liquid spray channel. The filter screen support includes an upper end, a middle block and a lower end, wherein the upper end and the lower end face inwardly and are respectively located above the liquid spray channel and below, a part of the liquid spray channel is horizontally occupied to form a mixing chamber, the middle block is located between the upper end and the lower end, and its setting direction is opposite to that of the upper end and the lower end, and it is horizontally arranged in the liquid spray channel, and the upper end The first channel is formed between the part of the liquid spray channel left empty and the middle block, the second channel is formed between the part of the liquid spray channel left empty at the lower end and the middle block, and the mixing chamber is connected with the first channel and the second channel respectively through the filter screen through.The invention adopts a unique filter screen structure, so that only one time is needed to scald the filter screen at high temperature, the time is short, and it is very convenient.

The components required to form a foam pump include a pump head, a net, a piston, a gasket, a pump valve, a bottle cap, a pump body, a spring, a glass bead ball, and a straw. The following is a schematic diagram of the structure of the foam pump:
