Patent number: 9204946Abstract: The spray assembly for a droplet spray teeth cleaning system includes a guidance member at the end thereof. The spray assembly includes a nozzle through which a spray of liquid is directed to the teeth for cleaning. The guidance member is configured and mounted relative to the nozzle to provide a selected standoff distance between the nozzle and the teeth and includes a portion which is configured to fit in the interproximal space between adjacent teeth and gums, or against the frontal portions of the teeth, so that the user knows the location of the spray relative to the teeth.Type: GrantFiled: August 24, 2007Date of Patent: December 8, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Garrett Kotlarchik, Joseph W. Grez, Craig Black, Bart J. Massee, Paul Bas, Peter Alexander Wachters, Katrina Rockey, Wolter Benning, Jerry Wood, Paulus Cornelis Duineveld, Jozef Johannes Maria Janssen, Petrus Henricus De Leeuw

Patent number: 8696609Abstract: A multi-switch (24) for an oral care appliance includes a switch housing (28) having a hollow chamber (30) therein, a button actuator (32) with at least two O-rings (42) around the periphery thereof, and inlet and outlet channels (50, 52) connecting a source of compressed gas (18) with the housing chamber and the housing chamber with a mixing chamber (26), respectively. A pump (60) moves fluid from a reservoir (20) to the mixing chamber. The O-rings are positioned so that as the button actuator is actuated and then released, the outlet is closed and the inlet is opened, allowing gas to move into the housing chamber. The pump is actuated, and then the inlet is closed and the outlet opens, allowing gas in the chamber to move to the mixing chamber to produce a stream of fluid droplets, which are directed out through a nozzle portion (16) of the appliance.Type: GrantFiled: December 9, 2008Date of Patent: April 15, 2014Assignee: Koninklijke Philips N.V.Inventors: Jozef Johannes Maria Janssen, Bart Gottenbos, Petrus Henricus De Leeuw

Publication number: 20090305187Abstract: The interdental cleaner includes a source of liquid (22) and a control system (42) including a manual pump (26), for moving a selected amount of liquid, suitable for a single use, into a liquid pathway and there to a mixing chamber (53). A source of pressurized gas (30), such as a CO2 cartridge, is used to preload a selected amount of gas into a gas chamber (52). The control system includes a spring-loaded button (18), which upon operation results in the manual pump (26) being operated, forcing the selected amount of liquid into the mixing chamber, and then upon release, permits the pressurized gas in the gas chamber to enter the mixing chamber, breaking up the liquid therein into droplets and a liquid stream, and propelling the resulting liquid out of a nozzle portion (14) of the cleaner into the interproximal area of the teeth.Type: ApplicationFiled: July 6, 2007Publication date: December 10, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Jozef Johannes Maria Janssen, Bart Gottenbos, Luciana Opran, Petrus Henricus De Leeuw, Dirk Brokken, Arjan Leo Van Der Sande

Patent number: 7040045Abstract: The invention relates to an iron having means for moistening fabric to be ironed. According to the invention, the moistening means comprise a device for generating foam and means for applying said generated foam to the fabric. For example, foam may be generated by means of a nozzle (21) having a first inlet (8) for a foaming liquid (6) and a second inlet (12) for supplying pressurized air to the nozzle so as to mix air with said liquid, thereby creating foam (42). Applying foam to the fabric (50) can be realized by means of a doctor blade (51) to break up the foam.Type: GrantFiled: November 12, 2002Date of Patent: May 9, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Amar Ashok Mavinkurve, Eduard Josephus Hultermans, Petrus Henricus De Leeuw, Nyik Siong Wong, Asok Kumar SO Kasevan
