Abstract

A ceiling fan easy for maintenance includes a motor housing, which is formed with an accommodating space having a motor provided therein. The motor is connected with a blade unit, and a switch box is provided beneath the blade unit and received therein with a driver, which is electrically connected with the motor. By so designing, in case the driver causes trouble and damage and need to be repaired, a maintenance man only need to open the switch box beneath the motor housing and the blade unit to carry out maintenance and dose not need to disassemble the motor housing. Thus, when doing maintenance work at altitude, the maintenance man can keep away from the blade unit of the ceiling fan, thus able to carry out maintenance of the ceiling fan with great safety and convenience.
