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.

The invention relates to an external cutting member (19) for use in a hair-cutting unit (13a, 13b, 13c) of a shaving device (1). An annular hair-cutting track (41) of the external cutting member has a central axis (43), a plurality of hair-entry openings (49), and hair-guiding elements (51) arranged between each pair of adjacent hair-entry openings. The hair-guiding elements each comprise an outer surface segment (55), an inner surface segment (57), a first side surface (59) bounding a first hair-entry opening (49a), a second side surface (61) bounding an adjacent second hair-entry opening (49b), a first cutting edge (63) at a location where the first side surface connects to the inner surface segment, and a second cutting edge (65) at a location where the second side surface connects to the inner surface segment. In a cross-section extending perpendicularly to a radial direction with respect to the central axis, each hair-guiding element has an imaginary middle axis (79) extending perpendicularly to the inner surface segment. The imaginary middle axis intersects the inner surface segment in a point of intersection (81) half-way between the first and second cutting edges, and divides a total cross-sectional area (A.sub.T) of the hair-guiding element into a first cross-sectional area portion (A.sub.1) including the first cutting edge and a second cross-sectional area portion (A.sub.2) including the second cutting edge, the total cross-sectional area being the sum of the first and second cross-sectional area portions. According to the invention, the first cross-sectional area portion of each hair-guiding element is equal to or smaller than 48% of the total cross-sectional area of the hair-guiding element. The invention further relates to a hair-cutting unit (13a, 13b, 13c) for use in a shaving device (1), comprising an external cutting member according to the invention and an internal cutting member (21) which is rotatable relative to the external cutting member about an axis of rotation (29), wherein the internal cutting member comprises first cutting edges (69) for co-operation with the first cutting edges of the external cutting member during rotation of the internal cutting member in a first rotational direction (R1), and second cutting edges (73) for co-operation with the second cutting edges of the external cutting member during rotation of the internal cutting member in a second rotational direction (R

A rotary shaver 1 comprises at least an external cutting element 7 and a disc-shaped element 10. The disc-shaped element covers at least part of the external cutting element. The external cutting element is at least provided with a passage 11. The disc-shaped element is at least provided with a pen 17 having a length, which pen is press-fitted in the passage. Between a wall 22 of the passage and the pen at least one vent 21 extends at least along the length of the pen. The pen is provided with at least three ribs 19 extending parallel to a central axis of the pen, wherein the at least one vent is located between adjacent ribs and the wall of the passage.

A shaving unit for a shaving apparatus includes at least first and second cutting units which respectively include first and second external cutting members having a plurality of hair entry openings respectively defining first and second shaving tracks. The cutting units further include first and second internal cutting members which are rotatable relative to, respectively, the first and the second external cutting members about first and second axis of rotations, respectively. The first cutting unit is pivotal about a first primary pivot axis which, seen in a direction parallel to the first axis of rotation, is arranged between the first shaving track and the second axis of rotation. Similarly, the second cutting unit is pivotal about a second primary pivot axis which, seen in a direction parallel to the second axis of rotation, is arranged between the second shaving track and the first axis of rotation.

A 4 blade electric shaver head adapted to be connected to an electric shaver that includes a handle and an electric motor for operating the shaver head. The head includes four rotary cutters arranged in a square configuration and four holders also arranged in a square configuration. Each of the holders holds one of the cutters. The inner edges of the four holders define a point at the center of the shaver head. A housing for the holders includes an upper surface. The holders are retained by the housing but are mounted for pivotal movement such that the inner edges and outer edges can move up and down. A spring biases the holders in a position wherein the outer edges lie above the upper surface of the housing and wherein the holders slant downwardly toward the center thereby forming a concave shaving surface. The holders are interconnected to each other so as to always pivot in unison.

A foam dispensing electric shaver apparatus for conveniently dispensing shaving foam includes a handle body having an insert cavity with a feed aperture extending through to an inner compartment. A foam insert is electively engageable within the insert cavity. A shaver is coupled to the handle body and comprises a neck coupled to a neck aperture, a head coupled to the neck, and a set of blades coupled to the head. A motor is coupled within the inner compartment and is powered by a rechargeable battery to drive the set of blades. A foam dispenser has a pump adjacent the insert cavity and a spout extending through the front side of the handle body. A dispense button coupled to the handle body activates the pump to draw foam from the foam insert and release it through a distal end of the spout.
