Summary:The utility model provides a full-edge-covering type inlet flange of a centrifugal fan, and relates to a centrifugal fan structure, the full-edge-covering type inlet flange of the centrifugal fan comprises an inlet cone flange used for being in butt joint with a shell flange of the centrifugal fan, and the shell flange and the inlet cone flange both comprise flat flanges used for being in butt joint and matched with each other. The inlet cone flange is composed of the flat flange and the edge covering structure, the edge covering structure and the flat flange are integrally formed through a die, the edge covering structure is used for being arranged outside the shell flange in a surrounding mode, and an adjusting gap is formed between an inner ring of the edge covering structure and the shell flange. When the inlet cone flange is in butt joint with the shell flange, the enough adjusting distance of the gap between the inlet cone and the impeller is reserved, it can be guaranteed that the inlet cone and the im
