초록 ▼

A coupling (10) for being mounted between the threaded end of the arm (16) of a shower through which water flows and the showerhead (18) for mixing liquid into shower water. The coupling (10) includes a coupling body (20) having an inlet portion and an outlet portion with a flow path defined therebetween. A mixing chamber (32) is mounted in fluid communication with the flow path through the coupling body (20) which serves to selectively mix liquid such as body lotion with the water. In this regard, a vacuum generated by a venturi serves to draw the liquid into the mixing chamber. The vacuum is selectively controlled by a vacuum actuator (52) which holds the vacuum until the shower is turned off.

A coupling for being mounted between the threaded end of the arm of a shower through which water flows, and the showerhead for mixing liquid contained in a remote reservoir into shower water, said coupling comprising: a coupling body defining an inlet portion for threadably receiving said end of said shower arm, and an outlet portion for being threadably connected to said head, said coupling body being provided with a first flow path extending from said inlet to said outlet portions to allow water and mixed liquids to flow therethrough, said first flow path defining a first section of reduced dimension terminating in a first orifice, a mixing chamber wherein said liquid is mixed with water exiting said first section of said first flow path, and a further section downstream from said mixing chamber, said further section being dimensioned less than said chamber and greater at its downstream end than said first section to enhance the mixing of said liquid and said water, said further section including a restricted flared bore between said mixing chamber and said downstream end of said further section; a fitting integrally formed with said body for receiving said liquid, said fitting defining a further flow path terminating in a second orifice which is in fluid communication with said mixing chamber at a point upstream from said first orifice of said first section of said first flow path; whereby venturi means are defined by said body for generating a vacuum at a location proximate said second orifice of said further flow path for drawing said liquid into said mixing chamber, and whereby said further section enhances the vacuum generated by said venturi means; and vacuum control means for commencing and venting the vacuum generated by said venturi means for mixing and terminating the mixing of liquid with said shower water, said vacuum control means including a further fitting integrally formed with said coupling body and defining a third flow path therethrough terminating in a third orifice which is positioned in fluid communication with said mixing chamber, said third orifice being upstream from said first orifice, said vacuum control means further including a vacuum activator button for controlling the flow of air through said third flow path, said flow path being vented proximate and around said button until said button is depressed at which time a vacuum is created for drawing fluid from said further flow path to mix liquid with said shower said vacuum activator button being biased towards an open position which allows venting of said vacuum in and around button through said third flow path and wherein said vacuum activator button remains closed under biasing forces of said vacuum.
