Title (EN) ADJUSTABLE VIBRATION ABSORBER FOR A PERSONAL CARE DEVICE
(FR) ABSORBEUR AJUSTABLE DE VIBRATIONS DESTINÉ À UN DISPOSITIF DE SOINS PERSONNELS
Abstract:
(EN) A vibration reduction assembly (200) including: (i) a shaft (240); (ii) a first component (210) positioned along the shaft and having a first face (212) comprising a plurality of magnets (230) positioned to alternate between a magnet having a first magnetic pole (232) at the first face and a magnet having the opposite magnetic pole (234) at the first face; and (iii) a second component (220) positioned along the shaft and having a first face (222) comprising a plurality of ferromagnetic extensions (260), wherein the first face of the first component is separated from the first face of the second component by a gap (280) having an adjustable first distance, and wherein a pair of the plurality of magnets interact via magnetic force with a respective one of the ferromagnetic extensions to reduce vibrations from a drivetrain to a housing portion of the personal care device.
(FR) La présente invention concerne un ensemble de réduction de vibration (200) comprenant : (i) une tige (240) ; (ii) un premier élément (210) positionné le long de la tige et présentant une première face (212) comprenant une pluralité d’aimants (230) positionnés pour alterner entre un aimant ayant un premier pôle magnétique (232) au niveau de la première face et un aimant ayant le pôle magnétique opposé (234) au niveau de la première face ; et (iii) un second élément (220) positionné le long de la tige et ayant une première face (222) comprenant une pluralité d’extensions ferromagnétiques (260), la première face du premier élément étant séparée de la première face du second élément au moyen d’un espace (280) ayant une première distance réglable, et une paire de la pluralité d’aimants interagissant par l’intermédiaire de la force magnétique avec l’une respective des extensions ferromagnétiques pour réduire les vibrations d’un train d’entraînement au niveau d’une partie de logement du dispositif de soins personnels.
