Title
(EN) FLUID-DISPENSING AND REFILLING SYSTEM FOR A POWER TOOTHBRUSH
(FR) SYSTEME DE DISTRIBUTION ET DE REMPLISSAGE DE LIQUIDE POUR BROSSE A DENTS ELECTRIQUE
Abstract
(EN)
The fluid delivery/refilling system includes a unit-of-use fluid reservoir for dentifrice or medication within a head portion of a power toothbrush, which is removable from the remainder thereof. A pump element is located in the brushhead and is configured so that the back and forth movement of the brushhead in operation results in fluid moving from the reservoir to a dispensing valve located in the brushhead. The dispensing valve has an end portion which is normally closed, opening under pressure of fluid from the pump. The refilling assembly is separated from the toothbrush and is configured to fit over the top of the toothbrush. A pump used in a power toothbrush for fluid delivery to the bristles. The pump includes a pump chamber with a piston ball located therein. The pump includes a fluid exit channel which connects the discharge end of the pump chamber with an opening in the brushhead in which the dispensing valve is located.
(FR)
Cette invention concerne un système de distribution et de remplissage de liquide comprenant un réservoir unitaire de liquide pour dentifrice ou médicament, déposable, logé dans la partie de tête d'une brosse à dent électrique. Un élément de pompage situé dans la tête de la brosse est conçu de telle sorte que les mouvements de va-et-vient de ladite tête de brosse pendant la marche fait passer le liquide du réservoir à une soupape de distribution située dans la tête de brosse. La soupape dispensatrice comporte une partie d'extrémité normalement fermée qui s'ouvre sous la pression du liquide débité par la pompe. L'ensemble de remplissage est distinct de la brosse à dent et est conçu pour s'emboîter sur le sommet de la brosse. La pompe de la brosse à dents électrique sert à alimenter les poils de la brosse en liquide. Cette pompe comprend une chambre de pompage renfermant un bille de piston. La pompe comprend un canal de sortie du liquide qui relie le côté décharge de la chambre à un passage dans la tête de brosse dans lequel est logé la soupape distributrice.
