Abstract
Disclosed is a hair dryer having a reverse blowing dust-removal function, comprising a housing, a fan module, an air inlet, and an air outlet. The housing has a pass-through airflow channel between the air inlet and the air outlet. The fan module is disposed within the airflow channel of the housing. A circuit control board is disposed within the housing. A microcontroller and a power supply drive module are disposed on the circuit control board. The power supply drive module is connected to the fan module. The micro-controller is connected to the power supply drive module. A reverse rotation button and a forward rotation button that are connected to the micro-controller are disposed on the housing. The micro-controller controls, in response to a reverse rotation signal output by the reverse rotation button, the fan module to rotate in a reverse direction by means of the power supply drive module.
