Problems solved by technology

The disadvantage of the aforementioned prior art is that the airflow generated when the axial flow fan rotates is oriented and integrated, and is immediately guided forward by the deflector of the fixed wing seat. A strong turbulent flow is formed between them, resulting in increased wind resistance and unsmooth air flow, which seriously affects its efficiency.

Abstract

The invention relates to a circulating fan structure. The circulating fan structure at least comprises a power component and a flow guiding component. The power component serves as a power source driving axial-flow fan blades, the axial-flow fan blades are arranged on a mandrel of the power component, and the radian of the outmost periphery of each axial-flow fan blade is equal to or close to the radian of the inner flow guiding wall of the flow guiding component, so that the output air volume and the output distance are increased. The flow guiding component is provided with a front safety net and a rear safety net, so that the safety of a user is protected. The inner flow guiding wall is arranged in the flow guiding component or flow guiding blades or inner flow guiding blades are arranged in the flow guiding component meanwhile so that the air flow can be concentrated and the directions of the air flow can be guided; in this way, the resistance is reduced, the flow of the air flow is increased, the output distance is increased, and the indoor airflow circulation effect is improved. In this way, the indoor temperature adjustment effect is improved through the circulating fan structure.

Description

technical field [0001] The present invention relates to the circulation fan structure, especially the radian of the outermost peripheral edge of the axial flow fan blade is equal to or close to the radian of the inner flow guide wall of the flow guide element, so as to increase the output air volume and distance; The guide wall or guide vanes are also provided to concentrate and guide the direction of the airflow, thereby reducing resistance, increasing the flow rate of the airflow, extending the distance of the airflow output, and improving the temperature adjustment effect of the indoor airflow circulation. Background technique [0002] The known axial flow fan, as described in Taiwan Utility Model Patent No. M370015 "Axial Flow Fan Bracket Components", includes a guide tube and an axial fan element and a fixed wing seat arranged in the guide tube. The inside of the flow tube accommodates the axial flow fan element and the fixed wing seat; the aforementioned fixed wing sea...
