Benefits of technology

The present patent is related to a fan blade structure that includes a hub, blades, and flow-guiding units. The hub has a hollow body shape and has a shaft hole in the center. The blades are evenly spaced around the hub and each blade has a windward surface, front edge, rear edge, outer edge, and connecting section. The blade also has flow-guiding units formed on the outer edge, which consist of three-dimensional protrusions. The technical effect of the invention is to provide improved airflow and reduced noise in the fan blade structure.

Problems solved by technology

In a high temperature environment, if there is no air circulation or airflow disturbance, it will often make people feel more stuffy, even sweaty and uncomfortable.
Due to high cost of the air conditioner, people generally choose the electric fan with lower prices and low power consumption.
However, in the conventional fan blade structure 3, the airflow is only guided by the blades 32, and there are no flow-guiding units that can be cooperated.
Accordingly, the conventional fan blade structure 3 cannot effectively increase the flow rate in actual use so as to cause a disadvantage that the flow rate is poor while being used and cannot meet the requirements of actual use.

Abstract

A fan blade structure includes a hub, a plurality of blades and a plurality of flow-guiding units. The hub includes an end surface, a mounting surface and a surrounding side. The hub has a shaft hole located in a center of the hub. The blades are disposed around the surrounding side of the hub at intervals. Each of the blades includes a windward surface, a front edge, a rear edge, an outer edge and a connecting section. The windward surface is configured to generate airflow. The rear edge is disposed opposite to the front edge. The outer edge is connected to the front edge and the rear edge, and the connecting section is connected to the surrounding side. The flow-guiding units are formed on the outer edges of the blades, respectively. Each of the flow-guiding units is composed of a plurality of three-dimensional protrusions.

Description

BACKGROUNDTechnical Field[0001]The present disclosure relates to a fan blade structure. More particularly, the present disclosure relates to a fan blade structure applied to various types of fans.Description of Related Art[0002]In a high temperature environment, if there is no air circulation or airflow disturbance, it will often make people feel more stuffy, even sweaty and uncomfortable. In order to improve such problems, an electric fan and an air conditioner have been developed to reduce environmental discomfort. Due to high cost of the air conditioner, people generally choose the electric fan with lower prices and low power consumption. In general, the electric fans can be divided into box fans, vertical fans, ceiling fans, etc. The electric fan is the most common tool used for cooling because the electric fan can accelerate the convection by creating the airflow while rotating, thereby reducing the temperature.[0003]A conventional fan blade structure 3 includes a hub 31 and a ...
