Abstract

L'invention concerne une brosse à dents électrique de désinfection portable, comprenant un corps de brosse à dents (20) ayant une source d'alimentation (10), une tête de brosse (21) s'étendant vers l'extérieur à partir d'une extrémité du corps de brosse à dents (20), et un couvercle de brosse (30) pour recouvrir la tête de brosse (21) dans un état reçu. Une lampe de désinfection par ultraviolets (41) est disposée à l'intérieur du couvercle de brosse (30). La paroi interne du couvercle de brosse (30) est pourvue d'un fil (39) connecté électriquement à la lampe de désinfection par ultraviolets (39) et d'un point de contact d'acquisition d'énergie (51) positionné à l'extérieur du couvercle de brosse (30) et connecté au fil (39). Un point de contact d'alimentation électrique (52) correspondant au point de contact d'acquisition d'énergie (51) est disposé à une extrémité du corps de brosse à dents (20) qui est proche de la tête de brosse (21). Le point de contact d'alimentation électrique (52) est connecté à la source d'alimentation (10) dans le corps de brosse à dents (20). Le placement de la lampe de désinfection par ultraviolets (41) à l'intérieur du couvercle de brosse (30) et l'adoption du couvercle de brosse (30) comme cavité de désinfection peuvent protéger la tête de brosse (21) et aboutir à une désinfection. Un ressort (39) est utilisé en tant que fil (39) et produit une force élastique sortante sur une broche métallique (51A), ce qui aide à conserver un bon contact électrique entre le point de contact d'acquisition d'énergie (51) et le point de contact d'alimentation électrique (52). Une carte de contrôle UV (40) est montée de manière à être inclinée par rapport au couvercle de brosse (30), et la lampe de désinfection par ultraviolets (41) est disposée à proximité de la tête de brosse (21), de telle sorte que la totalité de la tête de brosse est éclairée autant que possible.
