Definitions

  • Electric toothbrushes are known and widely used having a set of bristles mounted to a brush head that is driven by an electric motor inside a toothbrush handle.
  • the motor may be powered by a battery, also inside the handle, or from a power supply socket adjacent a point-of-use.
  • the brush heads are ro- tated and/or vibrated by the motor to enhance the operation of the toothbrushes for cleaning teeth.
  • For vibrating a brush head it is already known to provide various mechanical couplings, including gears, to convert rotational motion of the motor into oscillating motion at the brush head.
  • Such mechani- cal couplings tend to be complex, possibly unreliable, or expensive.
  • the mechanical connections between the drive shaft 12 and the brush heads is clearly seen in Figures 3 and 4.
  • the cranked end or pusher 14 intermittently and in turn moves the lugs 18 and 19 sideways, in opposite di- rections, to cause the brush head 16 to oscillate back and forth.
  • the link 20 moves back and forth about an arc and by engaging in the slot 21 causes the brush head 17 to oscillate.
  • the brush heads are preferably integrally formed with stub axles 21 and 22 that have bearing surfaces and that snap fit into appropriate and respective apertures (not shown) formed in the shank 11.
  • the lug 18 is vertically lower than the lug 19 to ensure, for clockwise rotation of the pusher 14, that the pusher does not jam.
  • the lug 19 is fixed, or integrally formed, in a position appropri- ately lower that the lug 18.
  • the complete vertical separation extending between the lugs 18 and 19 makes it unlikely that debris will collect or that the toothbrush cannot be easily cleaned in order to remove any debris that does collect around the pusher 14 and prevents the pusher being readily rotated to carry out its function.

Abstract

Cette brosse à dents électrique comprend un col (11) allongé et un axe (12) d'entraînement coudé. Deux ergots (18, 19) formés à la presse sont montés sur la périphérie d'une tête (16) de brossage, et entrent en contact avec l'axe d'entraînement de manière à produire une oscillation de la tête (16) de brossage lorsque l'axe (12) est entraîné en rotation. La tête (16) de brossage comprend un élément de liaison mécanique rigide qui transmet à son tour le mouvement oscillatoire à la tête de brossage.
