A rotary electric shaver includes a main body in which a first transmission mechanism, and a connecting portion is disposed; a head unit in which a plurality of blade units each having an outer blade, an inner blade being in sliding contact with an inner surface of the outer blade, and a driven shaft rotating the inner blade are disposed, and a second transmission mechanism that transmits a power of the first transmission mechanism to rotate the driven shaft is built, and which is connected to the connecting portion. The head unit has a first magnet disposed at a position corresponding to each of the blade units. The main body has a second magnet disposed at a position facing and repelling the first magnet.

Proposed is 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.

There is provided a rotary electric shaver which can easily prevent an outer blade which is undesirable to be brought into contact with a skin from coming into contact with the skin, by reducing the number of contact times of the outer blades in a head with the skin, even when the shaver is used in a state where the head is substantially parallel to the skin. A rotary electric shaver includes a main body having a drive shaft, and a head connected to the main body. At least one of a plurality of blade units has a fulcrum plate, a turning plate, a spring, and a fixing plate, and has a lock mechanism capable of changing a height position of at least one of outer blades corresponding one-to-one to the blade units.

A cutting unit of a shaving head of a shaving device, which cutting unit includes an external cutting member and an internal cutting member. In an interconnected condition, a holding force prevents the external and internal cutting members from moving apart. The holding force is at least exerted by a first central portion of the external cutting member upon a second central portion of the internal cutting member, and/or vice versa. The holding force may for example be provided by a snap connection or magnetic attraction between the first and second central portions.

There is provided a rotary electric shaver which includes an external outer blade having a plurality of hair inlet holes on an annular shaving surface, an internal outer blade, a rotationally driven external inner blade having a plurality of small blades coming into sliding contact with a rear surface of the external outer blade, a rotationally driven internal inner blade, an external inner blade rest base, and an internal inner blade rest base. The external outer blade has a cylindrical guide ring formed on an inner peripheral side of an inner wall portion, and the external inner blade has a plurality of guides which come into sliding contact with an inner peripheral surface of the guide ring to perform radial alignment with respect to the external outer blade.

A shaving apparatus has at least one cutting unit detachably coupled to a drive mechanism via a coupling having first and second coupling members. The second coupling member has a coupling cavity. A coupling head of the first coupling member is in a form-locking engagement in the coupling cavity to transfer a driving force, and is detachable from the coupling cavity by movement in an axial direction parallel to an axis of rotation of the cutting unit. The second coupling member has a plurality of recesses, each recess extending in a radial direction from the coupling cavity and being delimited by two radially extending side wall sections. Each of the two radially extending side wall sections forms an edge with a bottom surface of the second coupling member, and the edges of each recess converge in a radially outward direction in relation to the axis of rotation.

An electrical appliance for performing a cutting action on hairs present on an area of skin (7) comprises at least one assembly of a driven internal cutting member (5) for cutting off the hairs and an external cutting member (6) which serves for contacting the area of skin (7) and also for covering and contacting the internal cutting member (5). The cutting members (5, 6) are designed such that friction between them is related to their condition of wear in a predetermined way. Information relating to an actual condition of wear of the cutting members (5, 6) is determined by measuring a parameter related to the friction between the cutting members (5, 6) and processing the parameter, and such information is indicated to a user of the appliance.

A rotary cutting unit of a shaving head of a shaving device, which cutting unit includes an external cutting member and an internal cutting member. In an interconnected condition, a holding force prevents the external and internal cutting members from moving apart. The holding force is at least exerted by a first central portion of the external cutting member upon a second central portion of the internal cutting member, and/or vice versa. The holding force may for example be provided by a snap connection or magnetic attraction between the first and second central portions.

A hair-removal apparatus is provided that comprises a hair-removal device with a movable hair-removal component, which comprises at least a first hair-contacting member and a second hair-contacting member, which are movable relative to each other and which are configured and arranged to mutually co-operate for removing hairs by mutually exerting a contact force, a pressing component configured and arranged to generate said contact force by exerting a pressing force on the movable hair-removal component during operation, a skin proximity sensing component, and a force adjusting component. The skin proximity sensing component is configured and arranged to detect a relative distance between the movable hair-removal component and a portion of the skin with hairs to be removed. The force adjusting component is configured and arranged to adjust, during operation, the pressing force exerted by the pressing component in dependence on the relative distance detected by the skin proximity sensing component.

An electric razor for ergonomically and safely shaving contoured areas of the body, such as the armpit, pubic, and groin areas, without undue hand or wrist contortion. The razor features a cutting head of blades that are arranged to compositely form a spherical cap-shaped cutting surface.
