Abstract

L'invention concerne une douchette buccale avec une chambre de mélangeage (5) dans laquelle est disposée une tablette qui se dissous dans l'eau de rinçage, afin d'enrichir cette eau en produits actifs, de sorte qu'on obtient un bain de bouche. Selon l'invention, afin de régulariser le processus de mélangeage, un support de substrat (7) est disposé dans la chambre de mélangeage (5) pour recevoir une tablette soluble dans l'eau. Le support de substrat (7) est formé par un pot (8) ayant des parois fermées et un fond fermé (9). Le côté ouvert du pot (8), opposé au fond, se termine à distance à l'avant du couvercle de la chambre de mélangeage (5), de sorte qu'un passage annulaire se forme entre le bord du pot (8) et le couvercle (6). On obtient ainsi que la tablette n'est pas directement exposée au flux entrant, mais qu'un flux partiel de l'eau est d'abord soumis à une inversion d'écoulement. Ce flux partiel dévié dissout la tablette. Une eau fortement enrichie en produits actifs se trouve ainsi dans le support de substrat (7), qui est maintenant conjointement entraînée dans le pulvérisateur (3) par un flux partiel qui balaye le support.
