Problems solved by technology

[0002] At present, the traditional exhaust fan blades are one-piece structure, and the one-piece structure limits the overlap between the blades in the production process. Therefore, the hub needs to be designed with a larger size to ensure that the blades can be removed smoothly during injection molding. mold
After determining the blade angle, the size of the hub and the blade, if the requirement of low speed and large air volume is to be achieved, the cross-sectional area of ​​the blade must be increased. Higher disadvantages; and the hub and blades of the exhaust fan blades in the prior art do not have a split structure, and the packaging requirements are high and the transportation cost is high

Abstract

The invention discloses an exhaust fan blade and an exhaust fan with the exhaust fan blade, and relates to the technical field of exhaust fan equipment. The exhaust fan blade comprises a hub and multiple blades, and the hub comprises a wheel frame and supporting frames uniformly arranged along the peripheral wall of the wheel frame; and each blade comprises a blade seat installed along two adjacent supporting frames in a matched mode and a blade body arranged on the blade seat. According to the exhaust fan blade, the hub can be designed with a smaller size, the length of the blades can be extended as much as possible, and thus more air volume is obtained; and the structure is stable, the packaging volume can be reduced, and transportation and storage cost reduction are facilitated. The exhaust fan has small size, large air volume and low power consumption through the exhaust fan blade.

Description

technical field [0001] The invention relates to the technical field of exhaust fan equipment, in particular to an exhaust fan blade and an exhaust fan with the same. Background technique [0002] At present, the traditional exhaust fan blades are one-piece structure, and the one-piece structure limits the overlap between the blades in the production process. Therefore, the hub needs to be designed with a larger size to ensure that the blades can be removed smoothly during injection molding. mold. After determining the blade angle, the size of the hub and the blade, if the requirement of low speed and large air volume is to be achieved, the cross-sectional area of ​​the blade must be increased. High disadvantages; and the hub and the blade of the exhaust fan blade in the prior art do not have a split structure, and its packaging requirements are high and the transportation cost is high. Contents of the invention [0003] Aiming at the problems existing in the prior art, t...
