The air pump discharges the gas through the air guide pipe to above the baffle. After the pressure above the baffle is greater than the air pressure below the baffle, the baffle moves downward, and the sealing plug blocks the air outlet pipe again to achieve sealing of the air outlet pipe. The device discharges air from the bottom of the foaming tank to achieve air entering the foaming agent, and stirs the foaming agent through the stirring blades to achieve rapid mixing of the foaming agent and air. The air outlet pipe is set at the bottom of the gas disk and is sealed by the sealing plug to prevent the foaming agent from entering the gas disk.
