A detachable floating shaver includes a head, a casing having a third through hole, a main housing, a first floating member, and a second floating member. Through the connection and positioning relationship between the two parent and child pivot portions, that is, the first floating member and the second floating member, the head can achieve a cross rotation relative to the main housing. The second floating member has a connecting member; through the detachable connection between the second floating member and the connecting member, the head of the shaver is detachably connected, which is convenient for replacement, cleaning and maintenance and is more practical. The shaver can achieve 360 rotation through two parent and child pivot portions and two elastic sleeves, and the effect of floating contact of the shaver with the user's face is good.

Electric shaver (1) having a main body (3) and a shaving unit (5) coupled to the main body. The shaving unit has three hair-cutting units (9a, 9b, 9c) each having an external cutting member (11) with a skin-contact surface (13) with hair-entry openings (15) and an internal cutting member (17) which is rotatable relative to the external cutting member. The hair-cutting units each have at least one geometric parameter (w) that influences a hair-cutting process of each individual hair-cutting unit. The shaving unit can be positioned relative to the main body in at least two different angular positions about a central axis (37) of the shaving unit. A value of the geometric parameter of at least one of the hair-cutting units is different from the values of the geometric parameter of the other hair-cutting units.

A rotary electric shaver includes a gear case arranged inside a head unit, a lower gear arranged in a lower portion of the gear case, coaxially having an outer blade gear for driving an outer blade and an inner blade gear for driving an inner blade, an upper gear arranged in an upper portion of the gear case to drive the outer blade, and a transmission gear having an input gear arranged in the lower portion of the gear case and to which driving power is input from the lower gear, and an output gear arranged in the upper portion of the gear case to drive the upper gear, in which the input gear and the output gear are coaxial and a rotary shaft vertically penetrates the gear case. The driving power from the upper gear drives an outer blade drive gear for driving the outer blade.

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.

A transmission system (100) for use in an electric shaver comprises a first base portion (41), a second base portion (42), and a coupling arrangement (50) coupled to the respective base portions (41, 42) such as to convert a rotation of the first base portion (41) about a first rotation axis (A.sub.r1) into a rotation of the second base portion (42) about a second rotation axis (A.sub.r2). The coupling arrangement (50) comprises N coupling portions (51) which are each coupled to the respective base portions (41, 42), at least in a tangential direction relative to the respective rotation axis (A.sub.r1, A.sub.r2), wherein N is at least two. The coupling portions (51) are mutually coupled such that the coupling portions (51) are displaceable relative to each other only in an axial direction of a central axis (A.sub.c) which extends through center points (B.sub.c1, B.sub.c2) of the respective base portions (41, 42).

An electric hair grooming appliance includes a handle and a hair grooming device. The electric hair grooming appliance also includes a pivot assembly pivotably attaching the hair grooming device to the handle. The pivot assembly includes a spherical housing. The hair grooming device and the spherical housing are pivotable relative to the handle about at least two pivot axes extending through the spherical housing. The electric hair grooming appliance further includes a motor contained in the spherical housing. The motor is configured to drive the hair grooming device.

Electric shaver includes body, head having blade block, and head supporting part connecting body with head. Head supporting part includes swing supporting part supporting head swingably about two swing axes, and head float part so that head is movable up and down with respect to body. This configuration allows head to swing about the two axes, and thus head easily follows undulations of skin. Head is movable up and down with respect to body, and thus head sinks with respect to body when head is strongly pressed against the skin. The aspect provides electric shaver that has a high follow-up performance of head swinging according to undulations of skin and hardly irritates the skin strongly.

An outer blade for an electric shaver has slits. With bars extending along an outer-blade width direction, each of the slits is defined by respective ends of the bars, the respective ends being positioned side by side along an outer-blade length direction, and is defined continuously from one end to another end in the outer-blade width direction. At least one of two bars that define the slit is provided with a lifter that lifts hair by contact. The lifter is formed partway along the slit and extends between edges of the slit along the outer-blade length direction when viewed along the outer-blade width direction.

The present invention relates to a beard trimmer comprising a handle (18) and a casing (5) as well as a cutting system comprising one or more rotating cutting heads (1), said rotating heads comprising a movable blade (2) and a stationary blade (3), each head being surrounded by a crown-shaped comb (4), said comb being height adjustable and making it possible, during use, to adjust the distance between said blades and the skin and thus to cut the beard hairs to the desired length. The invention is characterized in that said casing is movably mounted on said handle, making it possible to create a gap (6) between the casing and the handle in order to rinse the cutting system.
