Abstract
The utility model discloses a multi-angle fan blade, which comprises a fan blade bracket, a side fan blade, an end face fan blade and a rotating shaft, wherein the side fan blade is arranged on the side circumference surface of the fan blade bracket; and the end face fan blade is arranged on the end face of the fan blade bracket. For the purpose of achieving the effects of multi-angle ventilation or heat dissipation, the side fan blade consists of more than one spiral blade, and the end face fan blade consists of more than one square blade. For the purpose of leading the fan blade to rotate stably through the rotating shaft, an inner cavity is arranged on the fan blade bracket which is fixed on the rotating shaft through the inner cavity. The multi-angle fan blade has a reasonable and simple structure and low production cost and is convenient for production, assembly and disassembly; and simultaneously, the multi-angle fan blade achieves the double-wind-direction ventilation or heat-dissipation effects, and greatly reduces the consumption of energy sources under the same condition compared with the prior fan.
Description
Technical field
The utility model relates to a kind of fan blade of blower fan, particularly a kind of multi-angle fan blade.
Background technique
Along with the development of society, the demand of blower fan is increasing, and especially in daily life and in the production of factory, blower fan becomes indispensable ventilation or sink.But the wind direction of present impeller of blower is provided with more single, requires can't play a good effect than higher place to ventilating or dispelling the heat for those.
Summary of the invention
The purpose of this utility model is the multi-angle fan blade that provides a kind of wind direction simple in structure, two to ventilate or dispel the heat for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of multi-angle fan blade that the utility model is designed, it comprises blade support, side fan blade, end face fan blade and rotatingshaft, is provided with the side fan blade on the side circumferential surface of blade support, is provided with the end face fan blade on the end face of blade support.For ventilation or the radiating effect that reaches multi-angle, described side fan blade is made up of more than one spiral vane, and described end face fan blade is made up of more than one square blade.For fan blade can steadily be rotated by rotatingshaft, on blade support, be provided with inner chamber, blade support is fixed on the rotatingshaft by inner chamber.
A kind of multi-angle fan blade that the utility model provides, it is not only rational in infrastructure, simple, and convenient production and loading and unloading, cost of production is low, and it has realized that also two wind directions ventilate or radiating effect, compare with blower fan in the past simultaneously, under equal condition, greatly reduce the consumption of the energy.
