  • Patent number: 10279493
    Abstract: A hair clipper has a vacuum system for collecting hair debris created by the cutting blades. Air flow through an adjustable air inlet is divided into multiple paths, including at least one primary flow path and at least one separate secondary flow path. A debris trap intersects both the primary air flow path and the secondary air flow path. The primary flow path allows air flow through a first path to be higher than a secondary air flow through the second path before debris accumulates in the debris trap. The primary air flow decreases as debris accumulates in the primary air flow path and the secondary air flow approaches and perhaps exceeds the primary air flow, whereupon some debris accumulates in the secondary air flow path as air is diverted through the secondary air flow path.

    Abstract: Electric shaver includes body, head having blade block, and head supporting part connecting body with head. Head supporting part includes swing supporting part supporting head swingably about two swing axes, and head float part so that head is movable up and down with respect to body. This configuration allows head to swing about the two axes, and thus head easily follows undulations of skin. Head is movable up and down with respect to body, and thus head sinks with respect to body when head is strongly pressed against the skin. The aspect provides electric shaver that has a high follow-up performance of head swinging according to undulations of skin and hardly irritates the skin strongly.

  • Patent number: 8151467
    Abstract: A cutter member for a rotary shaver includes a number of cutters arranged in at least two rings around a central axis, and a number of upwardly bent arms connecting the cutters to the central base. The rings are formed by bending some of the arms more outward and/or inward than others. Further, the cutter member may be made by consecutively cutting a blank of sheet material so as to have a number of arms with cutters and by bending some of the arms more outward and/or inward than others, so as to arrange the cutters in the at least two rings.

  • Patent number: 8104181
    Abstract: Provided are an outer blade for a reciprocation-type electric shaver and a method of producing the outer blade, the outer blade being capable of suppressing a deformation such as wrinkles or an undulation, without adding a new component, to thereby keep a good appearance thereof. A sheet material for forming the outer blade is bent into a shape projecting upward when viewed in the lateral directions. The sheet material has hair introduction holes, the peripheral edge of each hair introduction hole forming a projection section projecting inward beyond the other portion of the sheet material, the end surfaces of a part of the projection sections make contact with a reciprocating inner blade. The sheet material is formed with a deformation suppression section in a specific region not including the projection sections which make contact with the inner blade but including the projection sections which make no contact with the inner blade.
