Description

Technical Field

[0001] The invention relates to the technical field of industrial fans, in particular to a suspended industrial fan with adjustable angle. Background Art

[0002] Suspended industrial fans, also known as industrial ceiling fans, are based on aerodynamics and generate strong and stable airflow through the rotation of large-diameter fan blades. During operation, air resistance is minimized, and a large amount of air is pushed vertically to the ground, forming a 1-3 meter air flow layer on the ground to move horizontally. After encountering an obstruction, it is pushed upward to the roof, promoting overall air circulation.

[0003] At present, the existing industrial fan structure is generally composed of a hanger mechanism, a motor and a fan blade, such as an industrial ceiling fan disclosed in the prior art CN110219815B.
