A shaving head includes at least one cutting unit in which an external cutting member is subjected to a shaving action. The external cutting member is suspended relative to a holder of the shaving head through suspension means. The suspension means includes at least two pivot constructions, wherein one pivot construction enables a member of the suspension means to be pivotable relative to the holder. The other pivot construction enables the external cutting member to be pivotable relative to the suspension member. 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 manner, good contour following performance is obtained at two levels, in both relatively small and relatively large curvature changing areas.

A shaving unit and/or electric shaver having a lighting module for providing an optical heating function at a skin-contacting surface of the shaving unit. At least one aspect of the invention related to an optical arrangement for processing a visible light output for modifying a visible light profile provided at a light output surface, the visible light for providing a visual indicator of activation of the lighting module.

A shaver head for an electric shaver has at least two hair-cutting units, each of which includes an external cutting member and an internal cutting member that is rotatable relative to the external cutting member. Each of the hair-cutting units is supported by a supporting portion that is linearly movable under the bias of a spring member relative to a base portion of the shaver head between a first, retracted position and a second, extended position. The shaver head has a locking mechanism for selectively locking the supporting portion in a locked position relative to the base portion allowing a user to select different shaving modes.

The invention relates to a shaving head comprising at least one cutting unit (7, 7A, 7B). The cutting unit comprises a ring-like skin-supporting tilting member, being tillable relative to a shaving head main body (4, 8) about a first tilting axis, an external cutting member, an internal cutting member, and a retainer. According to the invention, the retainer is a multi-purpose retainer in that it provides simultaneously a locking function, a secondary tilting function and an anti-floating function. By virtue of the multi-purpose retainer, the shaving device delivers a high shaving performance and is also easy to clean.

A rotary electric shaver includes an outer blade whose upper surface functions as annular shaving surfaces having multiple hair inlets formed therein, and an inner blade that has a small blade which rotates while coming into sliding contact with a lower surface of the outer blade. The small blade is formed so that an inner blade base plate is partially erected, and is disposed in at least two rows on a circumference close to an outer periphery and on a circumference close to an inner periphery. There is provided a movable inner blade that has a movable small blade which is vertically movable along a front end surface in a rotation direction of the small blade, with respect to the predetermined small blade.

A shaver with a handle and at least two rotary shaving heads. The shaver driven by at least one drive shaft which protrudes from the handle, and a support structure for supporting the shaving heads onto the handle so as to have their joined shaving surface extend substantially perpendicular to the at least one drive shaft. The support structure is configured such that a space (A), restricted at one side by the shaving head and at the opposite side by the handle, is substantially open to its remaining, surrounding side.

A shaving head having a shaving unit that includes a shaving unit frame with a skin contacting face, and at least two cutting units each having an external cutting member and an internal cutting member A pivot structure includes inter-engaging portions of a support structure and the shaving unit that enable the shaving unit to pivot relative to the support structure. Each internal cutting member is rotatable by a central driving member via a separate cutter driving member, the central driving member being configured to transmit a driving force to each cutter driving member in a transmission location. The pivot structure is located in an internal area of the shaving head between the skin contacting face, the cutter driving members and the transmission locations. The pivot structure further enables the central driving member and the cutter driving members to pivot together with the shaving unit relative to the support structure.

A dry shaver unit includes a housing and a cutter blade assembly mounted in the housing. The cutter blade assembly includes a cutter blade and cooperating shear blade arrangement. The thickness of the shear blade varies over its surface, such that the spacing between a portion of the skin engaging surface of the shear blade and the opposite face thereof is increased as compared with the spacing required to achieve a close shave. The cutter blade assembly is mounted in the housing such that a plurality of portions of the shear blade having different thicknesses are simultaneously available for application to a surface to be shaved.

A rotary electric shaver includes a gear case arranged inside a head unit, a lower gear arranged in a lower portion of the gear case, coaxially having an outer blade gear for driving an outer blade and an inner blade gear for driving an inner blade, an upper gear arranged in an upper portion of the gear case to drive the outer blade, and a transmission gear having an input gear arranged in the lower portion of the gear case and to which driving power is input from the lower gear, and an output gear arranged in the upper portion of the gear case to drive the upper gear, in which the input gear and the output gear are coaxial and a rotary shaft vertically penetrates the gear case. The driving power from the upper gear drives an outer blade drive gear for driving the outer blade.

In a shaving unit for an electric shaver, a hair-cutting unit (30) comprises a housing (40) having a central axis (A.sub.c), an external cutting member (31) supported by the housing (40), and an internal cutting member (32) covered by the external cutting member (31). The external cutting member (31) is rotatable about the central axis (A.sub.c) relative to the housing (40), and the internal cutting member (32) is rotatable about the central axis (A.sub.c) relative to the external cutting member (31). The hair-cutting unit (30) further comprises a transmission unit (60) which is accommodated in the housing (40) and which comprises a first transmission member (61) mounted to the internal cutting member (32), a second transmission member (62) mounted to the external cutting member (31), and at least one intermediate transmission member (63, 64, 65) via which the first transmission member (61) is coupled to the second transmission member (62).
