Abstract

A tower fan has a shell, and the shell has a bottom plate, an outlet structure disposed on the bottom plate, and a top plate disposed on the outlet structure. The outlet structure has a shell plate module, an inlet module, and a guiding column each made by aluminum extrusion. The inlet module is detachably mounted on the bottom plate, and the top plate is configured to engage with the inlet module. The outlet structure is modular and is made by aluminum extrusion, which not only improves efficiency and convenience of detaching the shell but also decreases difficulties and costs of manufacturing the shell. The shell of the tower fan can further have multiple outlet structures disposed in mirror symmetry and multiple fan modules each corresponding to a respective outlet structure. Tower fans with double or more air volume can be provided without making extra molds.
