The invention relates to a cutting member (7) for use in a device for shaving hair. The cutting member comprises a meal substrate (15) which is provided with a cutting edge (9). At least a portion of the substrate including the cutting edge is provided with a protective coating (19). According to the invention the coating (19) comprises a plurality of stacked pairs (21) of layers, wherein each pair of layers comprises a first layer (23) mainly comprising carbon (C) and a second layer (25) mainly comprising a metal, and wherein each pair of layers has a thickness (TP) between 1 and 10 nm. The second layer preferably comprises Cr, Nb, Mo, Ti, V, or W. As a result, the coating has a superlattice structure which provides the coating with physical properties which are superior to the properties of the individual materials of the layers. In an embodiment wherein the second layer comprises Cr and each pair (21) of layers has a thickness of 1.8 nm, the coating (19) has a hardness that is approximately four times the hardness of Cr and provides a coefficient of friction between the cutting member (7) and the hair to be shaved which is considerably lower than the coefficient of friction which would be obtained without the coating.

A cleaning unit (1) is provided for cleaning an interior space (15) of a shaving head (10) of a shaver, which shaving head (10) comprises a movably arranged cutter member (20) for cutting off hairs and a contacting surface (14) for contacting a portion of skin to be shaved, which is provided with a plurality of holes for catching and letting through hairs to 5 be shaved off by means of the cutter member (20). In particular, the cleaning unit (1) comprises separating means (30) for constituting a physical barrier between two portions of an outer surface (13) of the shaving head (10) and for conveying cleaning fluid (41). During a cleaning process, an agitated flow of fluid (41) is realized in the interior space (15) of the shaving head (10) under the influence of a centrifugal pump action which is obtained when 10 the cutter member (20) of the shaving head (10) is in motion.

The invention relates to a cutting member (7) for use in a device for shaving hair. The cutting member comprises a steel substrate (15) which is provided with a cutting edge (9). At least a portion of a surface (27) of the substrate including the cutting edge is provided with a protective coating (19) having a hardness which is higher than a˜hardness of the steel substrate. According to the invention, the portion of the surface (27) of the substrate (15) provided with the coating (19) is nitride hardened. As a result, the substrate provides an improved mechanical supporting function for the coating. In this manner, the risk that the coating will break as a result of deformations of the substrate, which occur under', the influence of high mechanical loads on the coating and on the cutting edge (9), is considerably limited. Examples of suitable coatings (19) in combination with the nitride (hardened steel substrate (15) are diamond-Like carbon and coatings having a superlattice structure comprising carbon and a metal, e.g. Cr.

A shaving apparatus includes at least one cutting unit having an outer shaving surface or contacting the skin, interrupted by hair entry apertures, and an internal cutter which is drivable for movement along the hair entry apertures for cutting off hairs projecting through the hair entry apertures. A suspension member, via which the external cutter is suspended relative to the holder, is tiltable relative to the holder about a tilting axis located more closely to a first peripheral portion of the shaving surface than to a second peripheral portion of the shaving surface opposite to the first peripheral portion of the shaving surface.

A shaving head (3) comprises at least one cutting unit (4) in which an external cutting member (5) which has a function in contacting skin to be subjected to a shaving action is arranged, and which is suspended relative to a holder (8) of the shaving head (3) through suspension means. In particular, the suspension means comprise at least two pivot constructions, wherein one pivot construction enables a member (9) of the suspension means to be pivotable relative to the holder (8), and wherein another pivot construction enables the external cutting member (5) to be pivotable relative to the suspension member (9) as mentioned. Furthermore, a pivoting stiffness of a connection of the latter pivot construction is lower than a pivoting stiffness of the first pivot construction. In this way, good contour following performance is obtained at two levels, in both relatively small and relatively large curvature changing areas.
摘要:
The invention relates to a shaving head (5) comprising at least two bladeshaped cutting members (7, 7′, 7″) each having a straight cutting edge (9, 9′, 9″) extending parallel to a longitudinal direction (Y) of the shaving head. Each cutting member is supported in a cartridge (11) of the shaving head by means of a supporting member (17) which supports the respective cutting member in a supported area (23) on the respective cutting member. Said supported area extends over a predetermined distance (D) perpendicular to the longitudinal direction. Each supporting member has a first portion (25) in contact with the supported area at a location remote from the cutting edge of the respective cutting member and a second portion (27) in contact with the supported area at a location near the cutting edge of the respective cutting member. The first portion has a basic cross-sectional area, seen perpendicularly to the longitudinal direction, and the second portion has a reduced cross-sectional area. According to the invention, the second portion (27) of the supporting member (17) of at least one of the cutting members (7, 7′, 7″) extends over at least half of said predetermined distance (D). In this manner, the free space between two adjacent cutting members is considerably increased. As a result, the rinsability of the shaving head is improved, so that the risk of shaving debris accumulation between two adjacent cutting members is reduced.
