Abstract

La présente invention concerne un dispositif de pulvérisation de la surface intérieure d'une cuvette de WC avec un produit chimique nettoyant et/ou désodorisant. Le dispositif comprend un récipient pour le produit chimique, une buse de pulvérisation à travers laquelle le produit chimique peut être pulvérisé latéralement autour d'un périmètre de la buse, un conduit en communication fluidique avec le récipient et la buse de pulvérisation, un moyen d'acheminement du fluide pour acheminer le produit chimique depuis le récipient à travers le conduit vers la buse de pulvérisation, et un moyen de fixation de la buse sur un bord de la cuvette de WC. La buse de pulvérisation du dispositif de nettoyage de cuvette de WC automatique ou manuel peut fonctionner de sorte que le produit chimique soit appliqué sur toute la circonférence de la surface intérieure de la cuvette de WC, la cuvette de WC tout entière étant nettoyée sur sa circonférence.
