Description

Technical Field

[0001] The utility model relates to the field of axial flow fans, in particular to an axial flow fan which is easy to assemble. Background Art

[0002] Axial flow fans are widely used. They are fans in which the airflow direction is in the same direction as the axis of the fan blades. For example, electric fans and air conditioner outdoor fans are fans that operate in an axial flow manner. Axial flow fans are usually used in situations where the flow requirements are high and the pressure requirements are low.

[0003] When using, axial flow fans are usually applied to different parts, including roofs, walls, and floors. The assembly position of the axial flow fan is single and can only be used in a single position. At the same time, a filter is installed at the outer end of the axial flow fan and the filter is fixed by bolts. However, different usage scenarios require different filter replacements. When replacing the filter, the bolts need to be removed, causing inconvenience in assembly. Utility Model Content
