Abstract:
1. A liquid diffusing device with interchangeable nozzles, comprising: a support frame having a passageway configured to diffuse a liquid, said passageway having an inlet and an outlet defining a longitudinal axis, said inlet being arranged for coupling to a liquid feeding pipe; at least one nozzle removably and selectively attachable to said outlet in an operative position and having an inlet section and an outlet section of predetermined diameters such to provide a corresponding flow rate; and means for supporting in an inoperative position at least one additional nozzle with an outlet section having a differentiated diameter with respect to the at least one nozzle; wherein said support means comprise a nozzle-carrying plate monolithic with said support frame and provided with quick connect/disconnect means to connect said at least one additional nozzle in the inoperative position to said nozzle-carrying-plate; wherein said quick connect/disconnect means comprise a plurality of appropriately shaped holding seats each providing a support position for said at least one additional nozzle in the inoperative position; wherein said holding seats are provided along a peripheral portion of said nozzle-carrying plate and have side peripheral openings to allow an insertion of said at least one nozzle and said at least one additional nozzle by sliding along respective predetermined directions, each of said side peripheral openings being curved to receive and enable extraction of said inlet section of said additional nozzle from a respective side peripheral opening along a substantially radial direction relative to said longitudinal axis; wherein each of said at least one nozzle and said at least one additional nozzle has a peripheral slot on said outer wall of said inlet section, said slot being designed to snap couple and uncouple along said substantially radial direction with a counter-shaped peripheral edge of anyone of said holding seats; wherein said frame has a hollow tubular portion defining said passageway and a main body coupled to said hollow tubular portion to house a deflecting member for a peripheral diffusion of the liquid; wherein said deflecting member includes an upper plate provided with at least one radially extending deflection channel, each of said additional nozzles being radially offset relative to said upper plate; and wherein said holding seats are configured to allow a mounting of each of said at least one additional nozzle with the outlet section thereof oriented toward said deflecting member to optimize replacement efficiency.
