Patent ID: 8806756

Claim:
An electric shaving apparatus comprising: a housing ( 1 ) accommodating an electric motor ( 2 ); a shaving head ( 4 ) which mounts at least one perforated shaving foil ( 5 ) secured to said shaving head as a first shaving element; a second shaving element comprising under cutters ( 13 ) which cooperate with said foil to cut hairs that penetrate said foil; wherein said shaving head is connected to the housing in an oscillatory fashion by two leaf spring shaving head supports ( 6 ) that allow a transverse oscillation of the shaving head and with it of the shaving foil; wherein the electric motor includes a first oscillator ( 7 ) and a second oscillator ( 8 ) which are coupled to one another by a resonant spring ( 9 ); wherein said first oscillator includes one or a plurality of permanent magnets ( 11 ); wherein said second oscillator is U-shaped in cross-section to form two iron cores; around each of which a coil ( 10 ) is wound; said first oscillator mounting a drive pin ( 12 ) which engages an oscillatory plate ( 14 ) on which one or a plurality of said under cutters are fastened; wherein the oscillatory plate has fastened to its right and left hand sides one end of a leaf spring ( 15 ) whose other end is secured to the shaving head; and whereby movement of the first oscillator is transmitted by the drive pin to the oscillatory plate and onwards to the under cutters while, at the same time, the shaving head is excited to oscillate owing to its connection to the oscillatory plate via the leaf spring ( 15 ).
