Description

Technical Field

[0001] The utility model relates to the field of fans, and particularly relates to an axial flow fan with quick disassembly and assembly. Background Art

[0002] Axial flow fans are currently mainly used for cooling and ventilation in factories, warehouses, and public places. Since the air transportation path passes through the motor, axial flow fans are only suitable for transporting air without obvious particles and viscous substances. The scenarios where axial flow fans are used are usually on the surface of brick walls or steel structures at a certain height from the ground. The outer cylinder body is fixed, the motor tail faces inward, and the fan blades face outward, so as to exhaust the indoor air outward through negative pressure. The existing connection methods of axial flow fans are mostly screw butt joint and fixation for assembly, and the internal blades are all single-piece butt joint and fixation. The overall installation and removal are time-consuming and laborious, which is not convenient for installation and later maintenance and replacement. Therefore, an axial flow fan with quick disassembly and assembly is proposed. Content of the Utility Model
