Title:
AN ELECTRIC SHAVER WITH AN LED/LCD SPEED DISPLAY
Document Type and Number:
WIPO Patent Application WO/2009/065280
Kind Code:
A1
Abstract:
An electric shaver with an led/lcd speed display comprises a power circuit module, a motor module, a motor-driving module, a motor-detecting module, a charge control module, a module for sampling electric quantity of a self-provided power source, a temperature sampling module, a displayer, a MCU control circuit module and a motor-detecting circuit module. The motor-detecting module and the motor module are electrically connected to the MCU control circuit module so that the motor-detecting module can feed the detected potential signal into the MCU control circuit module and the MCU control circuit module can control the motor-driving module to control the speed and the output power by controlling the duty ratio of the output square wave and the frequency according to obtained signals, and the led or lcd of a display module can directly display them. The electric shaver can prevent the speed of a cutter head from varying because of resistance so that it can avoid clipping hair and ensure the normal operation.
