Problems solved by technology

In the existing fans, when the blades rotate, the only way to increase the air flow distance is to increase the rotation speed of the blades. In this way, the traditional blades will generate greater wind resistance, and at the same time generate greater wind noise, and produce The airflow blowing on the human body is very uncomfortable; in addition, the airflow distance that can be generated by traditional fan blades is very limited, resulting in a decline in the user experience of fan products

Abstract

The invention discloses a fan blade structure and a fan using the same. The fan blade structure comprises a hub and a plurality of blades annularly and uniformly distributed on the peripheral face of the hub. Each blade comprises a hub connection part, a sickle-shaped front edge, an S-shaped rear edge and a blade top edge located at the tail end of the outer side of the blade so as to being connected with the front edge and the rear edge. Blade tips are arranged between the blade top edges and the front edges and in arc shapes. The included angle between the tangent line L5 and the tangent line L4 of the two ends, connected with each blade top edge and each front edge, of the corresponding blade tip is a2, wherein a2 is within 40-50. According to the a fan blade structure and the fan using the same, noise produced by the fan is low while the air amount and air speed can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a fan blade structure and a fan using the fan blade structure. Background technique [0002] Fan refers to an electric fan used to generate wind to keep cool in hot weather. It is a device driven by electricity to generate air flow. It rotates through the fan blades configured inside to generate air flow and take away the heat of the human body to achieve the effect of cooling. In the existing fans, when the blades rotate, the only way to increase the air flow distance is to increase the rotation speed of the blades. In this way, the traditional blades will generate greater wind resistance, and at the same time generate greater wind noise, and produce The airflow blowing on the human body is very uncomfortable; in addition, the airflow distance that can be generated by traditional fan blades is very limited, resulting in a decline in the user experience of fan produc...
