Summary:The utility model belongs to the field of centrifugal fans. The utility model relates to a fan, in particular to a novel centrifugal fan. When an existing centrifugal fan pumps and exhausts air, dustin the air cannot be filtered and purified at the same time. The abrasion of the fan blades is fast; the service life is short. Proposed now is the following scheme, the centrifugal fan comprises a centrifugal fan body, a ventilation shell is fixedly installed on one side of the centrifugal fan body. A first mounting plate is fixedly mounted at the top of the centrifugal fan body, a first mountinghole is formed in the top of the first mounting plate, a first filter plate is movably mounted in the first mounting hole, limiting grooves are formed in the two sides of the first filter plate, connecting grooves are formed in the inner walls of the two sides of the first mounting hole, and limiting rods are slidably mounted in the two connecting grooves. The centrifugal fan is reasonable in structure and convenient to o
