An automatic cooling mechanism is provided for an electrical device having a high-temperature element and a rolling shaft. The mechanism includes a fan mounted within the electrical device and a transmission mechanism connected between the fan and the rolling shaft for transmitting rotational kinetic energy from the rolling shaft to the fan to rotate the fan for reducing the temperature of the high-temperature element.
