A blade cap is provided to shield a user from heat generated by operation of a blade assembly. The blade cap provides an insulative barrier between the blade assembly and the skin of the user. The blade cap may prevent discomfort or burns from the heat generated by the blade assembly. The blade cap includes openings, channels, projections, tabs, and other formations to allow the flow of air through the passageways between the blade cap and the blade.

The present invention is concerned with a skin treatment device and an interface for, preferably detachably, attaching a brush to a skin treatment device, wherein the skin treatment device comprises a drive unit, a component part driven by the drive unit to perform a rotatory and/or oscillating movement and a hood at least partially encasing said driven component part. One of said brush and said driven component part comprises at least two protrusions which both extend through openings in the hood when the brush is attached to the skin treatment device. At least one of said protrusions engages the other of said brush and said driven component part by snap fit when the brush is attached to the skin treatment device.

A comb for an electric trimmer includes a first outer tooth, a second outer tooth, and intermediate teeth positioned between the first outer tooth and the second outer tooth. Each of the teeth includes a skin-contacting edge and a slot defined between an overhang region and a base region located on the blade-facing side. Each intermediate tooth defines a tooth height representing the shortest distance between a base region and an outer-most point on the skin-contacting edge of each of the intermediate teeth. A first tooth height is defined by a first intermediate tooth and a second tooth height is defined by a second intermediate tooth. The first tooth height is greater than the second tooth height. The ratio between the first tooth height and the second tooth height is about 1:70 to about 3:16.

A hair guide including a support member detachably couplable to a hair cutting apparatus, and at least two annular hair guiding members each having a central axis and hair guiding elements extending radially relative to the central axis and arranged in an annular hair guiding zone. At least one hair guiding element has an inwardly directed rounded end portion arranged at a distance from the central axis such that, when the support member is coupled to the hair cutting apparatus, the rounded end portion is positioned, in a radial direction relative to the central axis, at least partially inwardly of an inner side wall of an annular cutting zone of an associated cutting unit of the hair cutting apparatus and, in an axial direction relative to the central axis, at a distance from an annular recessed area of a central wall portion of the associated cutting unit.

A clipper blade protector enabling a user to enclose and protect the blades and teeth of clipper devices by incorporating a sheath body, a volume of cushion material, and a blade-receiving concavity. The sheath body extends between a cover end and an opening, wherein the blade-receiving cavity is formed within the sheath body between the opening and the cover end. The volume of cushion material is externally distributed along the sheath body between the cover end and the opening, thereby cushioning any external impacts against the enclosed portion of the clipper device. This protection is proposed to prevent breakage of the blades and teeth of the clipper device, saving both time and money in avoided replacements costs and maintenance.

The present disclosure relates to an adjustment drive (50; 150) for a cutting length adjustment mechanism (24; 130) for a hair cutting appliance (10; 110), the adjustment drive (50; 150) comprising an actuator (52) that is configured to actuate a movable portion (40; 120) of the cutting length adjustment mechanism (24; 130) with respect to a housing portion (12; 112) of the hair cutting appliance (10; 110), and a movement sensor unit (66) that is configured to detect a movement of the hair cutting appliance (10; 110), involving at least one of an orientation change and a position change, and to output an adjustment control signal that is derived from the detected movement, wherein, in a length adjustment mode, the actuator (52) is operated on the basis of the adjustment control signal. The present disclosure further relates to a cutting length adjustment mechanism (24; 130) for a hair cutting appliance (10; 110), a hair cutting appliance (10; 110), and to a method of operating a cutting length adjustment mechanism (24; 130) for a hair cutting appliance (10; 110).

The present application relates to a domestic appliance (1) comprising a mechanical function unit (2) having a movable member (3), a housing (4) containing a motor (5) to operate the movable member to carry out a primary function of the appliance, and an electrical function unit (6) having an electrically operative member (7) to perform a secondary function of the appliance that supports the primary function performed by the mechanical function unit. The electrical function unit comprises a module (8) positioned between the mechanical function unit and the housing. The electrical function unit comprises a generator to convert mechanical energy generated by the motor located in the housing into electrical energy to power the electrically operative member.

A hair guide (500, 740) for a hair cutting assembly is provided. The hair cutting assembly comprises a cutting unit support member (102, 720) and at least two cutting units (106, 108, 110, 722, 724, 726), wherein each cutting unit has an external cutting member (112, 728) and an internal cutting member which is rotatable relative to the external cutting member about an axis of rotation (x), the external cutting member having an annular cutting zone (114) comprising hair-entry openings (116, 728a) provided at least in a main annular wall (115) of the cutting zone, and wherein each cutting unit is pivotable relative to the cutting unit support member. The hair guide comprises: a hair guide support member (502, 742) configured to be coupled to the cutting unit support member of the hair cutting assembly, and at least two annular hair guiding members (506, 508, 510, 744, 746, 748) each having a central axis (y) and a plurality of hair guiding elements (512) having a main direction of extension in a radial direction relative to the central axis (y) and arranged in an annular hair guiding zone extending about the central axis, wherein: each annular hair guiding member is arranged relative to the hair guide support member such that, when the hair guide support member is coupled to the hair cutting assembly, the annular hair guiding member is associated with a respective one of the at least two cutting units of the hair cutting assembly such that the plurality of hair guiding elements partially cover the main annular wall of the respective cutting unit, and each annular hair guiding member is pivotable relative to the hair guide support member such that, when the hair guide support member is coupled to the hair cutting assembly, the annular hair guiding member is pivotable together with the respective cutting unit.

The present disclosure provides a razor accessory with a camera to assist the user of a shaving razor, which razor accessory is configured to be mechanically attached to the shaving razor. The razor accessory may be provided with sensors to track the shaving movements of a user. The present disclosure also provides an application for a wearable computer device to track the shaving movements of a user.
