Definitions

  • Electric toothbrushes are using electric power suppllied usually by a battery to move the brush head rapidly, while the user hand is only guding the brush to the target teeth, the types of the automatic movement of the head are either oscillating side to side, or rotation-oscillation (where brush heads rotate in one direction and then to the other).
  • Electric brushes can be classified into two categories, according to the type of action that they employ: Vibration, or rotation-oscillation.
  • Vibration Vibration
  • rotation-oscillation a brushing technique similar to that used with a manual toothbrush is recommended, whereas with rotating-oscillating brushes, the recommended cleaning technique is to simply move the brush slowly from tooth to tooth.
  • Sonic or ultrasonic toothbrushes are the newest development in the field, using ultrasonic waves to clear the teeth, by vibrating the bristle at a high number of movements per minute.
  • a therapeutic Ultrasonic Toothbrush is published under publication No.: W0199400504, is disclosed in the art.

  • the provided electric toothbrush is based on moving the brush head in a circular motion, depending on a battery as a power source for an electric motor driving a drive shaft enclosed in a sealed casing inside the brush handle.
  • the drive shaft drives a sealed disc, that has at its other side near its edge (away from the center) another semi-flexible arm fixed to the disc, the rotation of the drive shaft drives the disc, while the disc drives the semi-flexible arm to rotate in a way, that its tip draws a circle, hence, installing the brush head on the other side of the rotatable arm, makes the brush head to rotates, following a circular path, but without changing the direction of its bristles, as a result, when the user holds the brush, with its brush head located near the gum, the brush head rotates toward the teeth lower side, and lets its bristle applies a pressure against the teeth crown while crossing it, then it rotates away from the teeth, to move down again, and then move toward the teeth gum, completing one circular rotation, and so on.

Abstract

L'invention concerne une brosse à dents électrique (20), ayant une pile (21), un moteur d'entraînement (24), un arbre d'entraînement (25) et un disque scellé tournant (26), basé à l'intérieur d'un boîtier scellé (22) à l'intérieur du manche (23) de la brosse (20), tandis qu'un bras semi-flexible tournant excentrique (27) est fixé d'un côté sur le disque scellé (26) près de son bord et fixé de son autre côté à la tête de brosse (28). L'arbre d'entraînement (25) fait tourner le disque (26) pour faire tourner le bras (27) afin de faire tourner la tête de brosse (28) dans une trajectoire circulaire, mais sans changer la direction des poils de la tête de brosse (28), de telle sorte que la tête de brosse (28) tourne vers le côté inférieur des dents et laisse ses poils (29) appliquer une légère pression contre la couronne de dents lorsqu'ils la traversent, puis tourne pour s'éloigner des dents, pour se déplacer à nouveau vers le bas, puis se déplace vers la gencive des dents, accomplissant une rotation circulaire, et ainsi de suite, en simulant parfaitement un brossage manuel réel des dents.
