[0002] Industrial fans can most efficiently promote the movement of large amounts of air, generate ultra-large air volumes, and form a moving, circulating airflow field in the space. They can effectively regulate the air circulation problems in industrial production workshops. The area blown by industrial fans is directly related to the diameter of the fan. Large industrial fans have a large coverage area, are easy to clean, and solve the problems of high noise and high energy consumption. Industrial fans can become strangled due to entanglement of foreign objects when rotating, so an anti-strangulation industrial fan is needed.

Although existing industrial fans can achieve the purpose of air circulation, they may be strangled due to attracting foreign objects during actual use, thereby affecting the normal operation of the industrial fan. In addition, the blowing angle of the fan needs to be adjusted manually, which reduces its practicality. Utility Model Content
