Electric hair dryer with liquid crystal display panel

Abstract

Disclosed is an electric hair dryer with an LCD panel. A hair dryer housing is internally provided with a controller unit electrically connected to the LCD panel and a data acquisition system, a power system connected to an input power supply, a heating wire unit and a fan motor unit. The data acquisition system is installed inside the hair dryer housing, and the LCD panel is installed on the surface of the hair dryer housing. The heating wire unit and the fan motor unit are connected to the controller unit independently. A thermometer is installed at the front end inside the hair dryer housing, and a fan speed sensor is connected to the fan motor. The electric hair dryer employs the LCD panel and the data acquisition system to display the real-time data such as the air volume and the temperature, thus meeting multiple demands.
