Abstract

The invention relates to a small centrifugal fan, which comprises a motor and an impeller fixedly connected with the rotating shaft of the motor. The impeller includes a chassis, an air inlet ring coaxially arranged with the chassis, and a Multiple blades, the inner ring of the air inlet ring is the air inlet for the airflow to flow in, the holes surrounded by the chassis, the air inlet ring and the two adjacent blades are the air outlets, and the centrifugal fan also includes A support plate that is rotatably connected to the end of the rotating shaft of the motor, a base plate that is parallel to the chassis and fixedly connected with the air inlet ring, and a plurality of connecting rods connected between the support plate and the base plate. The present invention uses slender connecting rods, bottom plates and support plates to fix the motor and impeller, and the connecting rods fixed near the air outlet are slender and will not block the outflow of air from the air outlet, thereby increasing the flow rate of the air and improving the The air volume is also reduced, and the noise generated by the airflow impacting the connecting rod is also reduced.

Description

technical field [0001] The invention relates to a small centrifugal fan. Background technique [0002] At present, most domestic industries that need fans use axial flow fans, but axial flow fans have the following disadvantages: complex structure, many faults, difficult maintenance, low efficiency, high noise, low static pressure, small air volume, and stability when working in parallel poor. Contents of the invention [0003] The object of the present invention is to provide a small centrifugal fan. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a small centrifugal fan, which includes a motor, an impeller fixedly connected with the motor shaft, and the impeller includes a chassis, and an air inlet ring coaxially arranged with the chassis And a plurality of blades fixed between the chassis and the air inlet ring, the inner ring of the air inlet ring is the air inlet for the airflow to flow in, and each hole sur...
