The invention relates to a shaving unit (11) for use in a shaving device (1). The shaving unit comprises a supporting member (19, 21a, 21b, 21c) and at least two hair cutting units (7a, 7b, 7c) supported by the supporting member. Each hair cutting unit comprises an external cutting member (25a) with hair-entry openings (31) and an internal cutting member (27a) which is rotatable relative to the external cutting member about an axis of rotation (41) and which has a plurality of hair-cutting elements (35). The shaving unit further comprises a retaining structure (23a, 23b, 23c) which is releasably couplable to the supporting member and which is configured to retain the at least two hair cutting units in an operational position relative to the supporting member in an assembled condition of the shaving unit. The retaining structure comprises, for each respective hair cutting unit of the at least two hair cutting units, a separate retaining member (23a, 23b, 23c) which is releasably couplable to the supporting member and which is configured to separately retain the respective hair cutting unit in an operational position relative to the supporting member independently from any other of the at least two hair cutting units. The retaining structure further comprises, for each respective hair cutting unit of the at least two hair cutting units, a locking member (67) comprising at least one locking element (79a, 79b) which, in the assembled condition of the shaving unit, is biased by spring force towards the external cutting member of the respective hair cutting unit and engaged by an engagement element (87a, 87b) of the external cutting member to prevent rotation of the external cutting member about the axis of rotation. The locking member provided for the respective hair cutting unit is separately arranged from any other locking member, provided for any other of the at least two hair cutting units, and integrated with the separate retaining member provided for the respective hair cutting unit.

A shaving unit (3) for use in a shaving device comprises a supporting member (5) and at least two hair-cutting units (6) connected to the supporting member (5), wherein each hair-cutting unit (6) comprises an external cutting member (10), a skin-supporting member (40) having a skin-supporting surface (41) at least partially surrounding the external cutting member (10), and an internal cutting member (20). Further, in each hair-cutting unit (6), the skin-supporting member (40) is pivotable relative to the supporting member (5) about both a first pivot axis (42) and a second pivot axis (43), independently from the skin-supporting members (40) of the other hair-cutting units (6), wherein the respective pivot axes (42, 43) are perpendicular relative to each other, and wherein a total range of a pivot angle over which the skin-supporting member (40) is pivotable about the second pivot axis (43) is equal to or larger than 15°.

A dreadlock grooming device including handle, a cylindrical housing attached to the handle, a power source, and a power control. The cylindrical housing includes a first-semi-arcuate-section and a second-semi-arcuate-section together forming a clamp of the cylindrical housing. The cylindrical housing includes a plurality of serrated blades positioned along an interior surface of the cylindrical housing provided to remove stray hairs from a section of hair within the clamp formed by the first-semi-arcuate-section and the second-semi-arcuate-section during use.

A shaver head (12) for an electric shaver (10) has at least two hair-cutting units (13), each comprising an external cutting member and an internal cutting member which is rotatable relative to the external cutting member, and each supported by a supporting portion (26). The supporting portion is linearly movable under the bias of a spring member (30) relative to a base portion (20) of the shaver head between a first, retracted, position and a second, extended, position. The shaver head has a locking mechanism (30, 32) for selectively locking the supporting portion in a locked position relative to the base portion. This allows a user to select different shaving modes.

A hair-cutting unit (4) for use in a hair-cutting appliance comprises cutting members (41, 42), a base member (5), and a supporting member (6) which is pivotable relative to the base member (5) and accommodates the cutting members (41, 42). The hair-cutting unit (4) further comprises a holding member (7) which is pivotable relative to the supporting member (6) between a holding position of holding the cutting members (41, 42) in an operational position in the supporting member (6), and a releasing position of releasing the cutting members (41, 42) for removal from the supporting member (6), and a biasing mechanism (8) which is configured to bias the holding member (7) towards the holding position. At least in an opened position of the supporting member (6), pivoting of the holding member (7) out of the holding position is prevented solely by the biasing force of the biasing mechanism (8).

The present application provides a shaving head assembly, a handle assembly, and an inductive shaver. The inductive shaver includes the shaving head assembly and the handle assembly. The shaver is configured with the first conductive path, the first end of the first conductive path is the holder or the cutters in the shaving head assembly, and the second end is connected to the circuit board assembly in the handle assembly. When shaving, the holder (or the cutters) is arranged approaching the human skin 1 such as the chin and cheeks; because the human skin has a certain electric charge, when the human skin directly contacts or approaches the holder (or the cutters), the holder (or the cutters) will absorb human skin capacitance formed between the approaching position and the ground, which is the first inductive capacitor.
