A magnetic suction fan, including: a fan assembly, a base, and a magnetic element. The fan assembly is configured to convert electrical energy into mechanical energy to generate airflow. The base rigidly is fixed to the fan assembly. The magnetic element exposed on the base, configured to magnetically secure the base to a ferromagnetic surface. The magnetic element includes a magnetic working surface with a magnetic attraction force sufficient to maintain the base fixed under vibration conditions. During use, a magnetic attraction force working surface provides a planar pulling force. The base is rigidly connected with the fan assembly to ensure that vibration energy is isolated by the base-magnetic attraction system and prevented from being transmitted to the fan assembly. The fan assembly continuously converts electrical energy into uniform and strong airflow, thereby providing operators with a cool and comfortable airflow supply experience.
