A shaver (10) includes a razor blade (20a, 20b) that cuts hairs coming into contact therewith. A heating element (26a, 26b) is bonded to the razor blade (20a, 20b). The heating element (26a, 26b) generates heat when an electric current is passed therethrough, the generated heat being directly supplied to the razor blade (20a, 20b). A battery (32) generates electric current, and electrical conductors (28, 30, 50, 52) route electric current generated by the battery (32) to the heating element (26a, 26b). A handle (16) is adapted to be held by a user for manipulation of the shaver (10). Suitably, the handle (16) houses the battery (32), and a head (12) houses the razor blade (20a, 20b) and heating element (26a, 26b) bonded thereto, the head (12) being selectively attachable to and detachable from the handle (16).

An electrical shaver includes a sealing end wall blocking the passage of liquid from the cutter head (preferably a plurality of cutter heads) to the electrical motor within the housing, and a magnetic coupling coupling the cutter head to the electrical motor by a magnetic field which penetrates the sealing end wall, thereby enabling the shaver also to be used for a wet shave as well as for a dry shave. In one described embodiment, the cutter head includes a rotary cutter member, a static cutter member enclosing the rotary cutter member, and a scraper member having a thin, hard, scraper edge at least partially enclosing the static cutter member and spaced radially from its outer edge so as to erect the hairs, and to taughten the skin as the static cutter member is moved over the skin while pressed against it to cut the hairs. Further described is an auxiliary device for cleaning and/or drying the shaver head after use in a wet shave or dry shave.

A reciprocating electric razor head includes a fixed blade and a fixed blade support for supporting and fixing the fixed blade. The fixed blade is provided with hair entrance holes for body hair to enter, and an inner side of the fixed blade is provided with a movable blade capable of moving backward and forward in a reciprocating manner relative to the fixed blade to cut off the body hair inside the hair entrance holes, such that the fixed blade obtains a very flat cutting working face contacting the movable blade without the need for additional precision machining.

An electric shaver includes a rod-shaped body part, a head part, and an interposer. The head part projects from one end portion, in a longitudinal direction, of the body part and swingably attached to the body part. The head part includes a shaving portion and a drive mechanism. The shaving portion is formed to be elongated in a direction orthogonal to a projecting direction of the head part and has paired blades configured to operate relative to each other. The drive mechanism is configured to drive at least one of the paired blades. The interposer is configured to support the head part swingably about a first swing axis parallel with a longitudinal direction of the shaving portion, and to be supported on the body part swingably about a second swing axis orthogonal to the projecting direction of the head part and orthogonal to the first swing axis. The second swing axis is located farther away from a tip portion, in the projecting direction, of a contact surface of the shaving portion to be brought into contact with a shaving area, than the first swing axis is.

An electrically powered slotted rotary shaver which provides the clean, close shave of a hand-held razor combined with the safety, comfort and convenience of an electric shaver. The slotted rotary shaver comprises a body portion and a shaving portion. The head portion is provided with one or more shaving head assemblies having fixed upper grids and lower rotary grids. The upper grids are positioned upon a shaft extending from motor positioned within the body portion of the shaver. The upper grids are advantageously separated into four pie-shaped quadrants held together at the center by a pivot point, and comprise a plurality of apertures disposed over the high surface active cutting area of the upper grid through which hair protrudes when the head portion of the shaver is placed against a user's skin. The edges of each quadrant of the upper rotary grid also include sharpened blades which are arranged diametrically opposite one another to define slots through which long and/or curly hair, as well as previously cut stubble protrudes when the head portion of the shaver is placed against the user's skin. The lower rotary grid which includes openings thereon, is disposed on motor shaft below the upper grid and is planerized through opposite magnetized polarity such that when the shaver is activated, the lower rotary grids spin at high speeds in a continually reversing clockwise and counterclockwise directions upon the motor shaft to create a scissoring action which cuts the hair which has protruded through the apertures and slot of the upper rotary grid and the openings of the lower rotary grid when the shaving portion of the shaver is placed against a user's face.

A rotary electric shaver including an outer cutter frame mounted on a shaver main body housing a motor therein, outer cutters held in an outer cutter mounting hole formed in this outer cutter frame the upper surfaces thereof providing skin contacting surfaces, and inner cutters that rotate while being pressed against the inner surfaces of the outer cutters and have cutter bodies for cutting hair entering hair introduction openings formed in the outer cutters; wherein the outer cutters are provided tiltable relative to the outer cutter frame, and the outer cutter frame is tiltable relative to the shaver main body.

A skin treatment device such as electric shaver, comprising a housing forming an elongated handle for manually moving the device along a body surface, a working head attached to said handle for effecting a treatment to said body surface, at least one detector for detecting at least one treatment parameter of said device, and a feedback indicator for indicating feedback information based on the detected treatment parameter to a user during the personal care treatment. More particularly, such feedback indicator includes a light emitter configured to emit light signals onto a mirror in front of a user.

A support arm 27 that is rockably supported on one end of a grip portion 2 and projects from the one end is provided. Both ends of a blade head 3 are supported by the support arm 27 such that the blade head 3 can rock around an axis extending along a reciprocating direction of an inner blade 14, and an axial direction of the rocking motion of the support arm 27 with respect to the grip portion 2 is set in a direction intersecting with the reciprocating direction of the inner blade 14. This configuration achieves an electric shaver capable of increasing the movable range of the blade head while preventing a main body from increasing in size.

A roller assembly for an electric razor includes a generally cylindrical roller driven by a drive arrangement to rotate about a central axis. The roller supports a number of blades, each having a cutting edge externally exposed and extending parallel to the central axis. Each blade moves across the skin of a user so as to slice through hair projecting from the skin of the user. The roller assembly further includes at least one filament wond in a helical path around the roller such that a gap between adjacent portions of the filament along the cutting edges is no more than about 8 millimeters.

An attachment particularly useful for adapting an electrical shaver for wet shaving, includes a cap having a scraping edge located to engage a user's skin forwardly of the cutter head, when the cap is attached to the shaver, to erect hairs and to tauten the skin before engaged by the cutter head. The attachment may also include a dispenser for dispensing a shaving lotion during shaving. Also described are an auxiliary cleaning device which may be used for cleaning or drying a shaver head, and a kit including some or all of the foregoing.
