Magnetic-attaching structure for a fan

Abstract

A magnetic-attaching structure for a fan includes a fan body and a magnetic unit. The magnetic unit is mounted with the fan body, and then the magnetic-attaching structure for a fan can be easily assembled or changed so that the air-inhaling or air-exhausting directions are also changed. The fans can be assembled conveniently and quickly, and additional fans can be added as required. No fixing holes are needed for the fans, nor are screws needed to fix the fans in place. The user can assemble or add fans conveniently as suits their requirements.
