Shaving head for a dry shaver

摘要

A shaving head for a dry shaver is capable of increasing the cutting efficiency, yet allowing the use of the inner cutter of simple structure. The shaving head has a slit cutter unit composed of an outer cutter (140) shaped to have a top surface for contact with a user's skin, and an inner cutter (240) in contact with a bottom surface of the outer cutter. The outer cutter has a U-shaped structure with a pair of legs (142) connected by a crossbar (141), and to have a plurality of slits (42) which are spaced in a lengthwise axis of the outer cutter to leave a plurality of bridges (44) each between the adjacent ones of the slits. The slits extend continuously over a full width of the crossbar and into upper ends of the legs in a direction generally perpendicular to the lengthwise axis, giving two straight slit paths (48) respectively on opposite width ends of the outer cutter. The straight slit paths on the opposite width ends are staggered with respect to each other along the lengthwise axis. Each of the bridges extends along the width axis of the outer cutter to make the bottom surface of the outer cutter smoothly continuous over the full length of the bridge, and that each bridge is formed at its longitudinal center with a deflection (46) which is angled with respect to the width axis so as to leave, between the adjacent ones of the deflections, an angled path through which the straight slit paths of each slit extends continuously.
