This invention relates to the field of steam appliance technology and discloses a novel steam flow channel structure, comprising a closed cavity formed by assembling a base plate, a mounting frame, a cover plate, a frame, and a top plate. The closed cavity contains a flow channel for water flow and vaporization. At least one water-blocking rib is provided on the inner wall of the flow channel.
