Abstract (en)
[origin: CN211082411U] The utility model relates to an anti-interference protective grid and a fan. The utility model relates to a protective grille (1) for a fan, comprising a planar perforated plate (2), in which a central ring (3) is arranged and which forms an insertion opening for a part of the fan, said perforated plate (2) comprising a plurality of holes (4) distributed over the entire surface thereof and arranged next to each other in a honeycomb structure. The protective grid is easy to manufacture and compact in structure, and noise generated by the fan is reduced in the operation period of the fan.
