Abstract
(EN)
Disclosed is a tooth brush in which a base plate (3) is buffered when bristles contact the faces of teeth. The tooth brush comprises a base plate (3), having a lot of bristles and high elasticity, which is composed of a soft material having good restoring force, and a base plate case (4) including a recess (11), in which a predetermined space (2) is formed between the base plate (3) and the bottom thereof. The tooth brush of the present invention buffers the base plate (3) according to upper, lower, left and right brushing directions of the tooth brush, and adaptably and elastically presses bristles against the curved faces of the teeth and gums, thereby solving a defect of the conventional tooth brush.
(FR)
L'invention concerne une brosse à dents comprenant une plaque de base (3) qui s'enfonce quand les soies entrent en contact avec les faces des dents. La brosse comprend une plaque de base (3) portant une pluralité de soies, présentant une élasticité élevée et constituée d'un matériau souple qui possède une bonne résilience; et un corps (4) présentant un évidement (11) dans lequel la plaque de base (3) et le fond du corps sont séparés d'un espace prédéterminé (2). Dans la brosse à dents de la présente invention, la plaque de base (3) s'enfonce en fonction des directions de brossage supérieure, inférieure, gauche et droite de ladite brosse et, de manière adaptée et élastique, presse les soies contre les faces courbes des dents et des gencives, ce qui compense un défaut des brosses à dents classiques.
