Device for diffusing a aromatic product in a water stream and associated diffuser body

Abstract

The present invention relates to a device for diffusing a fragrant product in a water stream. The device includes a main body with an inlet and an outlet for the water stream, interconnected by a channel for the passage of the stream. The main body is configured to be mounted on a water circuit with the inlet and the outlet arranged between an outlet of the water stream distribution system and a shower pipe inlet, respectively, so as to allow the water stream to circulate through the passage channel of the distribution system towards the shower pipe. The main body includes a receptacle configured to receive and position a diffuser body in the passage channel for the fragrant product to be diffused. The diffuser body blocking, at least partially, the passage channel such that, in the open position, the water stream from the outlet of the distribution system flows through the diffuser body when passing through the channel, causing the fragrant product to be diffused in the water stream and hence allowing a perfumed water stream to reach the shower pipe.

         6 . The diffuser body according to  claim 5 , wherein said first and second tubes are at least partially made of an elastically deformable material so that the pressure exerted on the top cover causes a deformation of the first and second tubes disengaging the bead from said groove to allow switching from the closed position to the open position of the receptacle. 
     
     
         7 . The diffuser body according to  claim 1 , wherein the first tube and the second tube comprise, on their respective peripheral wall, a plurality of through windows. 
     
     
         8 . The diffuser body according to  claim 7 , wherein the through windows respectively of the first tube and of the second tubes are positioned relative to each other such that:
 in the closed position, the through windows are offset from one another preventing the passage of the water flow inside the receptacle; and   in the open position, the through windows face each other allowing the passage of the water flow inside the receptacle.   
     
     
         9 . The diffuser body according to  claim 1 , wherein the aromatic product to be diffused, positioned inside the receptacle, includes aromatic salts. 
     
     
         10 . The diffuser body according to  claim 1 , wherein the aromatic product to be diffused, positioned inside the receptacle, includes a felt soaked in said aromatic product to be diffused. 
     
     
         11 . The diffuser body according to  claim 1 , wherein the aromatic product to be diffused, positioned inside the receptacle, includes a sponge soaked in the aromatic product to be diffused. 
     
     
         12 . The diffuser body according to  claim 1 , wherein the aromatic product to be diffused, positioned inside the receptacle, includes a porous stone comprising said aromatic product to be diffused.
