Title
(EN) SHOWERHEAD WITH MULTIPLE PAIRS OF NOZZLES THAT ACTUATE SEQUENTIALLY IN A LOOP
(FR) POMME DE DOUCHE AVEC DE MULTIPLES PAIRES DE BUSES QUI S'ACTIONNENT DE MANIÈRE SÉQUENTIELLE EN BOUCLE
Abstract
(EN)
A showerhead (2) and a pulsation mechanism thereof are disclosed. The showerhead (2) with three sets of spaced-apart nozzles (22a, 22b, 22c) is configured to be cyclically activated in sequence, with each set of nozzles (22a, 22b, 22c) operative for approximately 0.25 seconds to 1 second, while the other two sets of nozzles (22a, 22b, 22c) are deactivated. The showerhead (2) includes a shutter (34) adapted to open a flow passage (36) within the showerhead (2) leading to one or more respective nozzles (22a, 22b, 22c) periodically to produce an intermittent pulsating flow.
(FR)
Cette invention concerne une pomme de douche (2) et un mécanisme de pulsation de celle-ci. La pomme de douche (2) avec trois ensembles de buses espacées (22a, 22b, 22c) est configurée pour être activée cycliquement en séquence, chaque ensemble de buses (22a, 22b, 22c) fonctionnant pendant environ 0,25 secondes à 1 seconde, tandis que les deux autres ensembles de buses (22a, 22b, 22c) sont désactivés. La pomme de douche (2) comprend un obturateur (34) conçu pour ouvrir périodiquement un passage d'écoulement (36) à l'intérieur de la pomme de douche (2) conduisant à une ou plusieurs buses respectives (22a, 22b, 22c) pour produire un flux pulsé intermittent.
