摘要

A structure of filtering bag combination comprises a filter with folds to cover a support formed by surrounding rods. The support has bracing members to support the filter. The ends of the support are mounted with two shaping pieces and respectively an upper lid and a lower lid for fixing and sealing, thus the filtering bag combination is completed. A structure of filtering bag combination comprises a filter (2) with folds to cover a support (1) formed by surrounding rods (11). The support has bracing members (3) to support the filter. The ends of the support are mounted with two shaping pieces (4, 5) and respectively an upper lid (6) and a lower lid (7) for fixing and sealing, thus the filtering bag combination is completed. The upper lid has an air outlet (61) to connect an external air exhausting equipment. The bracing members are all serrated members, and are provided on an outer side of the support with numerous equidistantly separated crests and corresponding hollows having an inner side with a connecting base. The crests have on their top a clamping notch for placing the rod, so that the bracing members are transversely arranged within a circle formed by encircling the rods of the support. The filter is formed of a ventilating cloth with a series of folds. Inner folding areas (21) of the folds correspond by position to and are fixed on the hollows of the bracing members, while outer folding areas (22) of the folds are supported with the rods. After assembling, the folding areas formed by folding the filter do not generate dead corners.
