Abstract:
(EN) The present disclosure is concerned with a brush head for an electric toothbrush, in particular a replaceable brush head, comprising (a) a housing attachable to and detachable from a handle of the electric toothbrush, (b) a carrier having a mounting side, in particular having a circular, oval or elliptical mounting side, which carrier is mounted at the housing for driven oscillatory rotational motion around a rotation axis that extends through a center point on the mounting side of the carrier, and (c) wherein each of the tufts has a tufting area of at least about 2.0 mm2, in particular of at least about 2.80 mm2, and the filaments in each of the tufts have a cross-sectional area perpendicular to their length extension direction that corresponds to a circular cross sectional area having a diameter in the range of between 140 µm and 102 µm, in particular of about 127 µm, in particular wherein the brush head comprises only tufts of the defined type.
(FR) L'invention porte sur une tête de brosse à dents électrique remplaçable comprenant : a) un boîtier pouvant être fixé à la poignée de la brosse à dents électrique, (b) un support ayant un côté de montage circulaire, ovale ou elliptique, monté sur le boîtier pour un mouvement de rotation oscillatoire, autour d'un axe de rotation, qui s'étend à travers un point central sur le côté du support, et (c) chacune des brosses fait environ 2,0 mm 2- 2,80 mm 2, et les filaments dans chacune des brosses ont une aire de section transversale, perpendiculaire à leur direction d'extension de longueur, qui correspond à une aire de section d'un diamètre compris entre 140 µm et 102 µm, et d'environ 127 µm, où la tête de la brosse ne comprend que des brosses de type défini.
