Abstract

L'invention concerne un robinet de chasse d'eau d'un réservoir d'eau entraîné par un soufflet d'eau, utilisé pour commander le processus de rinçage d'un réservoir d'eau de toilettes, le robinet de chasse d'eau n'ayant qu'un seul bouton et étant apte à commander la quantité d'eau évacuée du réservoir d'eau en fonction de la profondeur à laquelle le bouton est pressé ; de plus, le bouton est extrêmement léger, et ne nécessite que 0,1 N de force pour se déplacer lorsqu'il est pressé. Le robinet de chasse d'eau a un soufflet d'eau (13), le soufflet d'eau (13) est relié à un noyau de vanne par l'intermédiaire d'un levier à câble, et le soufflet d'eau (13) est aplatie par la pression de l'eau dans le réservoir d'eau de toilettes, entraînant ainsi l'ouverture du noyau de vanne du robinet de chasse d'eau. Une vanne de commande (15) est reliée au soufflet d'eau (13), et commande l'entrée et la sortie de l'eau dans le soufflet d'eau (13). Un bouton (7) commande l'action de la vanne de commande (15), et la profondeur à laquelle le bouton (7) est pressée, commande le degré auquel la vanne de commande (15) s'ouvre lors de l'entrée d'eau dans le soufflet d'eau (13), régulant ainsi la quantité d'eau évacuée par le réservoir d'eau.
