[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. Commonly referred to fans include ventilators, blowers, and wind turbines.

[0003] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air induction of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and conveying of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0004] However, the main components of the existing fans, such as the motor and the impeller, are generally arranged in the middle of the wind tube. Since the wind tube is an integrated structure and the wind tube is long and narrow, when the motor or impeller and other components need to be repaired or maintained, it is difficult for the staff to directly contact the components that need to be repaired and maintained and perform the repair and maintenance work on them. The maintenance personnel need to put their bodies into the wind tube for maintenance, which is extremely inconvenient and affects the maintenance efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
