发明名称 Rotary dry shaver
摘要 A rotary dry shaver includes an outer shearing foil supported on a head frame and an inner cutter holder having a center axis and carrying a plurality of inner blades in hair shearing engagement with the outer shearing foil. The inner cutter holder is operatively connected to a rotary drive shaft of an electric motor so as to be driven thereby to rotate about the center axis. The outer shearing foil is held movable in the direction of the center axis relative to the head frame, while the inner cutter holder is movable along the center axis relative to the rotary drive shaft so as to be floatingly supported thereby. The dry shaver is characterized in that the outer shearing foil is connected to the inner cutter holder by means of a pin extending along the center axis such that the outer shearing foil and the inner cutter holder are movable together along the center axis relative to the head frame as well as the rotary drive shaft. Whereby contact pressure between the inner blades and the outer shearing foil can be kept substantially at a constant level irrespective of the relative movement of the outer shearing foil to the head frame.
