Title
(EN) CLEANING SECTION FOR AN ELECTRIC ORAL HYGIENE DEVICE
(FR) SECTION DE NETTOYAGE POUR UN DISPOSITIF D'HYGIÈNE BUCCAL ÉLECTRIQUE
Abstract
(EN)
A cleaning section (20) for an electric oral hygiene device (1) is proposed that has at least a first carrier mounted for driven rotation or oscillating rotation around a rotation axis (R), at least a plurality of first cleaning elements (40) mounted on the first carrier (30) with their bases arranged on the vertices of a first star-shaped polygon around the rotation axis, wherein the bases lie on a mounting surface (31) and the whole interior of the first star-shaped polygon is visible from the point where the rotation axis crosses the mounting surface, wherein all of the first cleaning elements are circumferentially inclined (alpha) with respect to the rotation axis such that the free end of each of the first cleaning elements is farther away in the circumferential direction than the base of the respective first cleaning element and wherein the circumferential inclination direction of all first cleaning elements is the same, and wherein at least one cleaning element property of adjacent first cleaning elements or adjacent clusters of first cleaning elements discretely alternates between a first configuration and a second configuration.
(FR)
L'invention concerne une section de nettoyage (20) pour un dispositif d'hygiène buccal électrique (1), laquelle section de nettoyage a au moins un premier support monté pour une rotation entraînée ou une rotation oscillante autour d'un axe de rotation (R), au moins une pluralité de premiers éléments de nettoyage (40) montés sur le premier support (30) avec leurs bases agencées sur les sommets d'un premier polygone en forme d'étoile autour de l'axe de rotation, les bases reposant sur une surface de support (31) et toute la partie intérieure du premier polygone en forme d'étoile étant visible à partir du point où l'axe de rotation croise la surface de support, tous les premiers éléments de nettoyage étant inclinés (α) circonférentiellement par rapport à l'axe de rotation de sorte que l'extrémité libre de chacun des premiers éléments de nettoyage soit plus éloignée dans la direction circonférentielle que la base du premier élément de nettoyage respectif et la direction d'inclinaison circonférentielle de tous les premiers éléments de nettoyage étant la même, et au moins une propriété d'élément de nettoyage des premiers éléments de nettoyage adjacents ou de groupes adjacents de premiers éléments de nettoyage alternant de manière discrète entre une première configuration et une seconde configuration.
