A rotary electric shaver of the present invention includes: an outer blade having an annular shaving surface provided with multiple hair inlets formed therein on an upper surface thereof; and an inner blade having a small blade which rotates in sliding contact with a lower surface of the outer blade, in which the outer blade has an integral structure using a resin material, and has a rib portion which is located between adjacent hair inlets.

A personal grooming assembly for PURPOSE includes a housing that may be gripped thereby facilitating the housing to be positioned on a user's body. A clipping unit is movably coupled to the housing. The clipping unit cuts hair when the housing is positioned on the user's body. A vacuum unit is coupled to the housing to vacuum hair clippings when the hair is cut. Thus, the hair clippings are removed from the user's body.

A rotary shaver (1) comprising a metal external cutting element (7) and a disc-shaped element (10) having a central axis (12). The disc-shaped element covers at least part of the external cutting element. The disc-shaped element is in contact with the external cutting element by means of a raised ring-shaped rim (15) extending between a side surface of the external cutting element and a side surface of the disc-shaped element, which raised ring-shaped rim has a height of at least 0.1 millimetre in a direction parallel to the central axis and a width of less than 0.35 millimetre in a direction radial to the central axis.

A guard element (4) for use in a hair cutting unit as a guard of a movable hair cutting element of the hair cutting unit has a disc-shaped base (10) and an annular wall (20) comprising a main part (21) extending from the periphery of the base (10), and a flange-shaped part (22) comprising an outwardly bent section (24). The annular wall (20) is reinforced on the basis of at least one of a design where a smallest inner periphery of the flange-shaped part (22) has a diameter which is smaller than a diameter of a largest inner periphery of a straight section (23) of the main part (21) connected to the periphery of the base (10), and a design where a free end section (25) of the flange-shaped part (22) is at least partially bent. In an embodiment, at least a portion of the main wall part (21) of the guard element (4) tapers inwardly in a direction along a central axis (11) of the disc-shaped base (10), from the disc-shaped base (10) to the flange-shaped wall part (22), such that the flange-shaped wall part (22) is enlarged with respect to a flange-shaped wall part (22) of a guard element (5) not having the tapered shape of the main wall part (21), resulting in increased stiffness and an increased resonant frequency of the guard element (4).

A nose hair clipper including a stationary external cylindrical body, having an external cutting portion with a plurality of first cutting edges, a plurality of first slits, and a plurality of rounded portions; a rotatable internal cylindrical body, having an internal cutting portion with a plurality of second cutting edges and a plurality of second slits, a convex portion, and a circumferential concave groove, the rotatable internal cylindrical body being inserted into the stationary external cylindrical body, and the plurality of rounded portions of the external cutting portion extending upward to be higher than an upper end of the internal cutting portion by a to predetermined gap; a bolt, screwed into the circumferential concave groove; a handling body, combined with a lower end of the rotatable internal cylindrical body; and an auxiliary cap with a brush and a driver, connected to a lower end of the handling body.

A shaving system (10) comprising a shaving device (12) having a shaving unit (38) and a cleaning device (14) for cleaning the shaving unit, the shaving unit having at least one hair-cutting unit (25) having an outer hair-cutting member with an annular shaving track (37) with a plurality of hair-entry openings (27) and an inner hair-cutting member rotationally arranged inside of the outer hair-cutting member. The cleaning device (14) has at least one liquid-injection nozzle arranged and positioned in a receiving pit of the cleaning device for generating a jet of the cleaning liquid that, when the shaving unit is supported in a cleaning position by the cleaning device, propagates directly through one or more of the hair-entry openings (27) of the shaving unit only in a single sector (41) of the annular shaving track (37) of the outer hair-cutting member (27) extending over at most one half of the annular shaving track.

According to an aspect, there is provided a computer-implemented method for providing visual feedback to a user of a rotary shaver. The method comprises (i) receiving movement measurements representing movement of the rotary shaver during a shaving operation; (ii) processing the received movement measurements to determine a representation of a trajectory of movement of the rotary shaver during the shaving operation; (iii) processing the determined representation to project the representation onto a two-dimensional plane; (iv) generating a graphical user interface, GUI, the GUI including the projected representation and a graphical template comprising an annular target zone for a correct circular motion of the rotary shaver during the shaving operation; and (v) displaying the generated GUI using a display unit.
