Publication number: 20130333220Abstract: A shaving apparatus having at least one cutting unit with an external cutting member and a rotatable internal cutting member each the external and internal cutting members having cooperating cutting edges forming bearing surfaces of a first bearing, and a second bearing with bearing surfaces. To minimize the friction between the cutting edges, a support device having visco-elastic properties is provided between the two bearings. During operation, the distance between the bearing surfaces of the first bearing adjusts to the distance between the bearing surfaces of the second bearing. During cutting of hairs, the support device behaves as a stiff element whereas during periods in which no hairs are cut, the support device behaves relatively soft so that the cutting gaps between the cutting edges are closed.Type: ApplicationFiled: December 20, 2012Publication date: December 19, 2013Inventors: Bastiaan Johannes De Wit, Fokke Roelof Voorhorst, Geert Veenstra, Leonardus Hendrikus Gerardus Johannes Segeren, Sieds Bosch, Sjoerd Haites

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

Publication number: 20120284950Abstract: The invention relates to a cleaning device (1) for removing particles from a surface (11). Thereto the device sprays droplets (200) of a fluid (201) into a space (213). The droplets (200) are expelled from a rotatable brush (3) as a mist of droplets. Air carrying dirt particles (202) is exposed to the mist, whereby dirt particles coalesce with droplets in the mist in the space (213). The coalesced particles (22) are conveyed to a cleansing unit (14) to be separated from the air. Finally, clean air exits from the device (1).Type: ApplicationFiled: July 29, 2010Publication date: November 15, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Bastiaan Johannes De Wit, Fokke Roelof Voorhorst, Johannes Tseard Van Der Kooi
