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.

There is provided an apparatus (100) for determining a location of a personal care device on a user. The apparatus (100) comprises a processor (102) configured to detect a location of one or more parts of the body of a user, detect motions of at least one of the parts of the body of the user induced by the personal care device when the personal care device is in use and determine the location of the personal care device on the user based on the detected motions of the at least one part of the body of the user in relation to the detected location of the at least one part of the body of the user. The processor (102) is configured to acquire images of the user from an imaging sensor (108) directed at the user, and detect the location of the one or more parts of the body of a user and the motions of the at least one part of the body of the user induced by the personal care device from the acquired images of the user.

A haircutter handle has upper and lower housings. The upper housing and lower housing join to form a circumvoluted and/or spiraled exterior surface. The handle narrows and extends axially from a blade end to a handle or gripping end. The blade has an upper blade that oscillates over the lower blade to cut hair. The handle has a reduction taper that facilitates gripping and/or handling the handle. The taper also orients the motor and battery so that the center of gravity is positioned within the palm of the user's hand when gripping the handle. The blade end of the handle has a width and/or height that are greater than a width and/or height at the handle end. The reduction in height and/or width dimensions define a taper. In some embodiments, the width tapers more than the height tapers to facilitate gripping the handle about the center of gravity.

System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

A cutting mechanism for a hair cutting apparatus, such as a shaving apparatus, includes an outer cutting member having hair-entry openings and an inner cutting member having cutting elements each having a first cutting edge. The inner cutting member is moveable with respect to the outer cutting member so as to perform a cutting operation within a cutting region of the cutting mechanism. Adjacent hair-entry openings are separated by a dividing element having a cutting section that lies within the cutting region and a non-cutting section that is outside the cutting region. The non-cutting section includes an inner wall facing the inner cutting member and a side wall which is substantially perpendicular to the inner wall. A single chamfer is provided between the inner wall of the non-cutting region and the side wall of the non-cutting region.

A surface-mountable holder includes a rear surface adapted to be coupled with an affixing mechanism for mounting to an external surface. The surface-mountable holder further includes a front surface configured to magnetically secure a shaving razor. The front surface is adapted to receive an upper handle portion of the shaving razor. The upper handle portion is in close proximity to a razor portion of the shaving razor.

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 disclosure provides an electric razor that reduces damage to the skin during shaving. Electric razor according to the present disclosure comprises head portion that holds comb-shaped outer blade and mesh-shaped outer blades each extending in a first direction so as to be movable in a second direction intersecting the first direction, comb blade urging members that urge comb-shaped outer blade in the second direction, mesh blade urging members that urge mesh-shaped outer blades in the second direction, and engaging mechanism that, when mesh-shaped outer blades are moved toward unit base against urging force of mesh blade urging members, moves comb-shaped outer blade in a state where comb-shaped outer blade does not project from mesh-shaped outer blades with respect to unit base.

The present disclosure provides a blade unit that achieves both smooth skin sliding in a wide area and ease of shaving in a narrow area. Blade unit according to the present disclosure comprises four or more outer blades extending in a first direction and sliding member extending in the first direction, and blade unit is attached to electric razor, wherein at least two outer blades included in the four or more outer blades are arranged on both sides of sliding member.

There are many trimmer models with 2 main parts, the static comb blade and the side moving cutter blade driven by electric motor/vibrator. These blades differ in many ways, shapes, sizes . . . which require fine adjustments and tenth of millimeter clearance at the end of the blades. Some models come with an adjuster that fits its model only with a fixed clearance that cannot be modified and does not fit other models. The proposed inventions are universal trimmer blades adjusters that fit most trimmer blades models and the clearance can be varied to meet the users' requirements. First invention design has one moving part with non-linear smooth adjustments and second invention design has two moving parts with linear fine adjustments.
