The upper mounting plate 11 and the lower mounting plate 12 are annular and a plurality of connecting rods 13 are circumferentially spaced apart around the center of the ring, whereby the bracket 1 thus formed is simple and compact in structure.

A mounting hole 131 is defined between the adjacent two connecting rods 13, the upper mounting plate 11 and the lower mounting plate 12. Thus, by adjusting the number of the connecting rods 13, the number of the mounting holes 131 formed in the bracket 1 can be made different, so that the filter 100 can have a different structure so that the filter 100 satisfies different types of purifiers.

The plurality of filter devices 2 are respectively disposed in the plurality of mounting holes 131, and the filter device 2 covers the corresponding mounting holes 131. Thereby, the shape of the filter 100 is substantially annular, the structure is simple and compact, and the installation of the filter device 2 can be modularized, cost-saving, and the filter 100 can be applied to a wider range. For example, by providing different numbers of filter devices 2, the filter 100 can have different purification capabilities, purification functions, and sizes, so that the above parameters can be appropriately adjusted according to actual needs. Of course, the provision of a larger number of filter devices 2 allows the filter 100 to have a larger purge area, thereby improving the purification capacity of the filter 100. In addition, the plurality of filter devices 2 can also be arranged to have different purification functions, whereby a plurality of contaminants can be removed.

Ring, hexagonal ring, etc., but not limited to the above shape. When the upper mounting plate 11 and the lower mounting plate 12 are of a polygonal ring shape, the number of the connecting rods 13 can be the same as the number of sides of the above-mentioned polygonal ring shape, whereby the structure of the filter 100 can be made simpler and more compact. For example, when the upper mounting plate 11 and the lower mounting plate 12 are all three-sided annular, four-sided annular, five-sided annular or six-sided annular, three connecting rods 13, four connecting rods 13, and five connecting rods 13 can be correspondingly arranged.
