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 air inlet 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 the airflow impacts the connecting rods is reduced.
Description
Technical field
The present invention relates to a kind of Small Centrifugal Fan.
Background technique
At present the industry of domestic demands blower fan adopts axial-flow blower mostly, and there is following shortcomings in axial-flow blower: complex structure, fault are more, maintenance difficult, efficient is not high, noise is large, static pressure is low, air quantity is little, less stable during parallel operation.
Summary of the invention
The object of the invention provides a kind of Small Centrifugal Fan.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of Small Centrifugal Fan, it comprises motor, the impeller that is fixedly connected with the rotating shaft of motor, described impeller comprises the chassis, with the air supplying ring of the coaxial setting in chassis and be fixed on the chassis and air supplying ring between the multi-disc blade, the interior ring of described air supplying ring is the intake grill that air-flow flows into, described chassis, each hole that air supplying ring and adjacent two blades surround is exhaust outlet, and centrifugal blower also comprises the dunnage that rotates and be connected with the roller end of described motor, parallel and chassis and the base plate that is fixedly connected with air supplying ring, be connected to many connecting rods between dunnage and the base plate.
Impact the noise that produces for reducing air-flow and blade, described blade distributes take the center of circle on chassis as the round dot circular array, and nearly end is blade tip from the center of circle for it, from the center of circle away from an end be blade root, described blade root is extended to blade tip along arc and radian is increased progressively by blade root to blade tip.
Be fixedly impeller and motor, described connecting rod is comprised of transverse part and vertical portion perpendicular and that be fixedly connected with, and described transverse part is parallel to base plate and end and dunnage and is fixedly connected, and described vertical portion is fixedly connected perpendicular to base plate and end and base plate.
Further, described connecting rod has 3～6.
Further, described connecting rod circular array is distributed in around the dunnage.
Owing to adopt technique scheme, the present invention has the following advantages: the present invention adopts elongated connecting rod, base plate and dunnage that motor and impeller are fixed, be fixed near the connecting rod of exhaust outlet and be elongate, can not stop the outflow of exhaust outlet air-flow, improved the flow of air-flow, improve air quantity, also reduced the noise that the gas shock connecting rod produces simultaneously.
