Patent number: 8505205Abstract: A personal care system includes an electrical shaver and a cleaning device for cleaning a shaving head. The cleaning device further includes a displacing system for displacing its supporting member relative to a cleaning fluid container from a first position in which the shaving head, when the shaver is supported by the supporting member, is not in contact with the cleaning liquid in the container, to a second position in which the shaving head is at least partially immersed in the cleaning liquid in the container. The cleaning device does not need any pump for displacing the cleaning liquid. Rather, activation of the shaving head that causes, e.g., rotation of a cutting unit, provides a sufficient pumping effect for the cleaning liquid when the shaving head is immersed in the cleaning liquid.Type: GrantFiled: June 21, 2005Date of Patent: August 13, 2013Assignee: Koninklijke Philips N.V.Inventors: Dirk Hendrik Wevers, Sint Baron, Gerben Raap, Jan Postma, Renger Ypenburg, Bastiaan Johannes De Wit, Jacob Brinkert, Fokke Roelof Voorhorst, Klaas Kooijker, Alastair Ian Blake

Patent number: 7797834Abstract: A device for shaving hairs growing from skin including a base portion having a grip, a shaving head which carries at least one cutting member having at least one cutting edge, and an actuator for effecting a periodical motion of the cutting member relative to the base portion to improve the cutting action of the cutting member. The shaving head is pivotable relative to the base portion about a pivot axis and the periodical motion of the cutting member is a periodical motion relative to the shaving head. The position and orientation of the geometrical path of the periodical motion of the cutting member relative to the skin is well-defined, so that the risk of skin irritations and skin injuries is considerably reduced.Type: GrantFiled: December 1, 2004Date of Patent: September 21, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Roelof Steunenberg, Peter Hans Van Der Vlis, Robert Alexander Van Eibergen Santhagens, Marinus Christiaan Hansen, Marc Alexander Pastoors, Dirk Hendrik Wevers, Aafje Gijsbertha Koster, Gerardus Joannes Henricus Roddeman, Richard Pieter Ophof, Hendrik Klaas Paauw, Gerben Raap, Raymond Wilhelmus Louis Lafarre, Johannes Cornelius Antonius Muller
