  • Patent number: 9956697
    Abstract: A personal care device is provided with a cutting unit comprising an external cutting member and an internal cutting member. A virtual skin plane is located on a side of the external cutting member facing away from the internal cutting member. The internal cutting member comprises cutting elements each having a first cutting edge. The external cutting member comprises hair-entry apertures each having a second cutting edge. In a starting position of cutting a hair situated in a cutting position in the hair-entry aperture and extending perpendicularly to the virtual skin plane, the first cutting edge is in contact with the hair in a first contact position, and the second cutting edge is in contact with the hair in a second contact position, wherein the first contact position is closer to the virtual skin plane than the second contact position.

  • Patent number: 9555551
    Abstract: A shaving unit includes a cap having an annular shaving track defining an axis. The shaving track is provided with hair entry apertures which have a V-shaped forward edge with a point directed in a cutting direction. Further, a rotary cutter has a plurality of cutter blades, where the rotary cutter is configured to rotate about the axis such that the cutter blades follow the shaving track in the cutting direction to cut hairs protruding through the hair entry apertures. The cutter blades have a V-shaped cutting edge, where a point of the V-shaped cutting edge is directed opposite to the direction of rotation of the rotary cutter.

  • Publication number: 20160158947
    Abstract: A personal care device, such as a shaving apparatus, provided with at least one cutting unit (21) comprising an external cutting member (23) and an internal cutting member (22) which is moveable relative to the external cutting member (23) in at least one direction of movement. A virtual skin plane (10) is located on a side of the external cutting member (23) facing away from the internal cutting member (22). The virtual skin plane (10) extends parallel to said direction of movement and parallel to a skin surface when the cutting unit (21) is in an operational position relative to the skin surface. The internal cutting member (22) comprises a plurality of cutting elements (39) each comprising a first cutting edge (50). A projection of the first cutting edge (50) in the virtual skin plane (10) encloses at least a first shearing angle with said direction of movement.
