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.
