PRESSURE HEAD WITH FOAMING FUNCTION

A pressure head with foaming function mounted onto a container with liquid substances includes a low-pressure suction force generator with a reducing port set into the discharge pipe of the pressure head, such that liquid already absorbed to the discharge pipe can flow through the guide port of the discharge pipe. The liquid is then collected and extruded from the reducing port, thus increasing the flow speed and reducing the pressure to generate a low-pressure suction force. An it guide port is arranged onto the discharge pipe and also located at a spacing with the reducing port. While the liquid is extruded from the reducing port to generate low-pressure suction force, air out of the discharge pipe is absorbed from the air guide port to the discharge pipe, such that an is mixed with liquid, making the liquid extruded from the discharge pipe foamed.
