Abstract

The invention discloses a fan blade structure of a fan. The fan blade structure comprises a body which is provided with a middle ring part, a connecting part and a guide part, wherein the middle ring part is provided with a through hole; the connecting part is provided with a plurality of connectors; the two ends of the connector are separately connected with the middle ring part and the guide part; the guide part is provided with a carrying ring part; a plurality of fan blades are arranged on at least one side of the carrying ring part. The fan blade structure of the fan can improve blade strength and reduces fan noises.

Description

[0001] 【Technical field】 [0002] A fan blade structure, especially a fan blade structure capable of reducing noise and enhancing the fan blade structure. [0003] 【Background technique】 [0004] There are two main types of current fans, centrifugal fans and axial fans. The two types of fans have different effects of forced airflow, and are used in different places. Axial fans enter from the top of the fan blades and are guided by the blades. The fan comes out from the bottom, and the centrifugal fan blade can guide the airflow in and out from the side through the design and matching with the fan casing or windshield, or enter from the top of the fan and exit from the side. Centrifugal fans can be set as top-in and side-out or side-in and side-out, so centrifugal fans are suitable for relatively narrow spaces. [0005] It is known that the fan blades of centrifugal fans are mainly made by injection molding (it can be integral injection of plastic or metal fan blades). One end ...
