Electric shaver with swinging cutter unit

摘要

An electric shaver is of a type including at least one spirally-bladed cylindrical rotary cutter cooperable with a finely perforated stationary blade foil. The shaver includes a motor casing including a drive motor accommodated therein and having first and second upright walls spaced a distance from each other and accommodated in a shaver casing with the first and second upright walls protruding upwardly outwardly from the top end of the shaver casing; and a cutter assembly including a generally U-shaped support structure having first and second arms spaced a distance from each other. While the support structure is mounted above the motor casing with the first and second arms pivotally coupled respectively with the first and second upright walls so as to define therebetween a common axis about which the cutter assembly swings relative to the motor casing, the spirally-bladed cylindrical cutter is rotatably mounted on the support structure so as to extend between the first and second arms in parallel relation to the common axis, and a foil-like perforated stationary blade member mounted on the support structure so as to cover the cylindrical cutter in substantially sliding contact therewith. A transmission gear train is disposed within the first arm for transmitting a drive of the drive motor to the spirally-bladed cylindrical cutter.
