Abstract

The invention relates to a small centrifugal fan. The centrifugal fan comprises a motor and an impeller fixedly connected with a rotating shaft of the motor; the impeller comprises a base plate, an air inlet ring and a plurality of blades fixed between the base plate and the air inlet ring; the air inlet ring and the base plate are coaxially arranged; an inner ring of the air inlet ring is an airinlet for flowing of airflow; each hole encircled by the base plate, the air inlet ring and the two adjacent blades is an air outlet; the centrifugal fan also comprises a support plate rotationally connected with the end of the rotating shaft of the motor, a bottom plate parallel to the base plate and fixedly connected with the air inlet ring, and a plurality of connecting rods connected between the support plate and the bottom plate. The elongated connecting rods, the bottom plate and the support plate are fixed with the motor and the impeller, and the connecting rods fixed nearby the air outlets are slender and do not block the flowing of the airflow of the air outlet, so that the flow rate of the airflow is improved, the air quantity is improved, and meanwhile, noise generated when theairflow impacts the connecting rods is reduced.

Description

[0001] technical field [0002] The invention relates to a small centrifugal fan. [0003] Background technique [0004] 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. [0005] Contents of the invention [0006] The object of the present invention is to provide a small centrifugal fan. [0007] 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 ...
