The power generation module continues to work, generating current and driving the motor, and the motor drives the fan to rotate the blade. The fan continues to rotate, allowing the heat generated by the fireplace to spread out continuously, efficiently, and energy-efficiently, thereby quickly convecting heat throughout the space.
