Sealing structure on vertical type air foam generator

The utility model discloses a sealing structure on a vertical type air foam generator. One end of the vertical type air foam generator is a liquid inlet. A cover plate which seals an opening is arranged at the opening in the upper portion of one end of the vertical type air foam generator. A handle is arranged on the cover plate. A mixed liquid outlet is formed in one side of the vertical type air foam generator. The liquid inlet is connected with a liquid inlet pipe which extends into a foam chamber and is placed below the mixed liquid outlet. A sealing ring is assembled on a pipe opening of the liquid inlet pipe, and sealing is carried out through a sealing cover. The sealing structure has the advantages that the height of the liquid inlet pipe is lowered, the resistance of the liquid inlet is lowered, machining difficulty is lowered, production cost is saved, conveying is convenient, repeated using can be achieved, and waste is lowered.
