Touch hair drier

Abstract

The present invention disclosed a touch hair drier, wherein it comprises: a housing supporting a power device and a heating device, and a touch handle connecting the housing; the power device and the heating device are powered by an energized circuit, and the circuit is provided with a control switch element configured to control the operation of the power device and the heating device. During the operation of the hair drier, only if the collecting unit collects any holding power exerted on the touch handle, the control switch element is in the conducting state, and then the power device and the heating device are initiated. Therefore, the touch hair drier in the present invention is designed to prevent from fires caused by the heat generated from the heating device which is on operation for a long continuous time. Hence, the touch hair drier possess high safety.
