  • the invention in one aspect is an oral cleaner for teeth and mouth which includes a first portion which is able to be hand held and an ultrasonic generator unit which activates a second portion of the oral cleaner which portion is adapted to be received in the mouth and vibrate.
  • the invention in another aspect is a method of cleaning teeth and the mouth including the steps of filling the mouth with a fluid, locating an ultrasonic generator within the mouth and causing the generator to operate which, in turn, causes ultrasonic vibrations of the water and cleaning of objects which have the vibrating water impinging thereon.

  • the material of the handle is preferably of some material which is comfortable to hold and tending to dampen any vibration such as rubber.
  • vibrating portion 30 is adapted to be received in a user's mouth.

  • the user's grip on the handle is preferably loose so as not to effect the dampening of the vibration or the grip portion is isolated from the ultrasonic generator.
  • the power for the operation of the ultrasonic generator can be provided by batteries located within the handle of the device and, if required, the device can be sealed and a form of inductive connection between a power source and the circuitry associated with the batteries can permit charging of the batteries from an external source. Alternatively, there may be a plug connection to a power source.
  • the device can be connected to an external power source, preferably a low voltage source, by means of a flexible cable or the like. If required, the device could run on mains power and be connected to this by way of connection through a flexible conductive pair to a power point.
  • an external power source preferably a low voltage source
  • the strength of the signal supplied by the ultrasonic generator can be adapted to permit complete cleaning in a predetermined time and, if required, the device could be provided with a number of operating conditions supplying more or less power for different persons.

Abstract

L'invention concerne un procédé de nettoyage des dents et de la bouche consistant à remplir la bouche avec un fluide, à localiser un générateur d'ultrasons dans la bouche et à faire fonctionner ce dernier, lequel, à son tour, produit des vibrations ultrasonores dans l'eau et entraîne le nettoyage des objets sur lesquels l'eau en vibration vient frapper. L'invention concerne également un appareil de nettoyage des dents et de la bouche.
