Title:
HAIR DRYER HAVING REVERSE BLOWING DUST-REMOVAL FUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/052313
Kind Code:
A1
Abstract:
The present application discloses a hair dryer having a reverse blowing dust-removal function. The hair dryer comprises 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 micro-controller 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 connected to the micro-controller and a forward rotation button connected to the micro-controller are disposed on the housing. The micro-controller controls, in response to a forward rotation signal output by the forward rotation button, the fan module to rotate in a forward direction by means of the power supply drive module. 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. The micro-controller only responds to the reverse rotation signal output by the reverse rotation button when the forward rotation button is not being triggered. The present application has a high dust-removal efficiency feature.
