A shaving apparatus (1) having a first shaving unit portion (7) connected to a main housing (2) and accommodating a single driven input member (9) rotatable about an axis of rotation. A second shaving unit portion (8) of the shaving apparatus has a hair-cutting unit (12) and a drive unit (13) which transmits a driving force from the single driven input member to an internal cutting member (19) of the hair-cutting unit. The second shaving unit portion is manually rotatable relative to the first shaving unit portion about the axis of rotation of the single driven input member. An adjustment system (24) has a sensing unit (28, 29) configured to have an output property which varies with the angular position of the second shaving unit portion relative to the first shaving unit portion about the rotational axis. The adjustment system adjusts an operational parameter of the shaving apparatus in dependence on the output property of the sensing unit.

This disclosure is concerned with a personal care device with a treatment head being pivot-mounted around a pivot axis, the personal care device having a pin having a pin head, a cam element having a cam surface, a spring element biasing the pin head and the cam surface against each other, wherein the cam surface is shaped such that it defines a rest position at which the biasing spring force provided by the spring element with which the pin head and the cam surface are pushed against each other has a non-zero minimum value, and wherein a pivoting of the head around the pivot axis causes the pin head to move along the cam surface and the cam surface is further shaped such that the spring force pushing the pin head and the cam surface against each other increases with increasing pivoting angle.

An attachment for a personal care device, such as a shaving or trimming device, is configured to be releasably coupled to a coupling structure of the personal care device by a coupler. The coupler includes a shaft having at least one coupling recess on the circumferential surface thereof. The coupling recess has a central portion and first and second side portions arranged on opposite sides of the central portion. The coupling recess also includes a sloped surface arranged in at least the central portion. When the attachment is coupled to the coupling structure, the sloped surface is engaged by a spring of the coupling structure. At least one of the first and second side portions of the coupling recess is recessed relative to the sloped surface, seen in a direction parallel to the central axis of the shaft.

Provided herein is a shaving apparatus capable of collecting cut hair, the apparatus includes a head shaving portion that includes a cutting portion having a cylindrical screen comprising a plurality of openings, an outer surface and an inner surface defining an inner cavity; a cutting component comprising one or more cutting elements, the cutting component positioned adjacent to the inner surface of the cylindrical screen to cut hairs that pass through the openings in the screen; and an inner cradle positioned within the inner cavity, the inner cradle is configured to collect cut hair.

The present invention relates a tool head for a personal care appliance, including a plurality of tool rotors rotatably supported about rotor axes and a drive train for rotatably driving said tooling rotors from a motor, wherein such drive train includes: an input crank element having connection means for connecting to a drive shaft, a transmitter element configured to be driven by said input crank element, and output crank elements configured to be driven by said transmitter element to rotate about said rotor axis.

A shaver for a shaving apparatus includes at least first and second cutters which respectively have first and second external cutting members with a plurality of hair entry openings which define, respectively, first and second shaving tracks. The cutters each have an internal cutting member which is respectively rotatable relative to the corresponding external cutting member about first and second axis of rotation. The internal cutting members are respectively connected to first and second driven transmission element via first and second drive spindles. The driven transmission elements are included in a transmission unit, where the drive spindles extend from the transmission unit via an open space, which is present between the transmission unit and the cutting units, and respectively pass through an opening in a bottom wall of a first housing of the first cutting unit and a second housing of the second cutting unit.

A hair cutting device includes a grip, a head disposed external to one end of the grip, the head including a cutting unit that works on hair, and a joint connecting the grip and the head. The joint includes a base connected to one of the grip and the head, and a slide portion connected to the other of the grip and head and held to be slidable within a predetermined area on a slide plane that is a plane intersecting an alignment of the grip and the head. Accordingly, the hair cutting device including the head that has an excellent ability to lessen impact which is made when the head hits the skin and to follow the skin surface is provided.

An electric shaver having a shaving unit (3) and a sensor (15) with a first sensor unit (16) fixed to a main body (2; 202; 302) and a second sensor unit (17) fixed to a sensor unit carrier (22; 222; 322), for indicating a distance between the sensor units (16, 17). The shaving unit (3) and the sensor unit carrier (22; 222; 322) are suspended to the main body (2; 202; 302) for displacement along a z-axis between a rest position (22) and a pushed-in position (22′) in response to a pushing force exerted onto a shaving face (11) of the shaver (1). The first and second sensor units (16, 17) are located in positions offset from the z-axis over a distance (d) in an x-direction. An anti-tilting guide (24-27; 124; 224, 226; 326, 328) is provided for guiding the sensor unit carrier (22; 222; 322) against tilting about a y-axis.

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 hair cutting appliance includes a receiving receptacle for receiving a connector plug to detachably connect a cutting unit to a housing of the hair cutting appliance. The receiving receptacle includes a receiving socket having a receiving recess adapted to receive an engagement element of the connector plug, and a biasing unit arranged in the receiving socket underneath the receiving recess. The biasing unit includes first and second biasing elements laterally spaced with respect to each other and arranged to receive the engagement element of the connector plug. The first biasing element includes a retaining contact portion configured to define the receiving position of the engagement element in an insertion direction (Z). The second biasing element includes an alignment contact portion configured to define the receiving position of the engagement element in a longitudinal direction (X) and in a lateral direction (Y).
