Single-use long-life faucet-mounted water filtration devices

Abstract

Single-use long-life faucet mounted water filtration devices are disclosed. A bathroom water filtration device having two outlets for filtered water is disclosed. Additionally, a fountain head is included for use in the bathroom water filtration device. The water filtration device is of unibody construction formed by ultrasonically welding certain parts thereof together. Since the devices disclosed are disposable, no filter replacement or other maintenance is performed. A gate, magnet, sensor and electronics provide an indication of filter performance enabling disposal of the water filtration device and installation of a new device. A kitchen water filtration device is larger than the bathroom device. Both the kitchen and bathroom water filtration devices are small and are mounted behind the faucet connection so as to facilitate full utilization of the sink or wash basin.

         44 . A water filtration device having an outlet fountain comprising: a filter; a generally cylindrically shaped filter housing having a wall defining said filter housing; said wall defines the interior and exterior of said filter housing and said wall includes an interior and exterior portion thereof; said filter housing includes an inlet and an outlet each of which extend through said wall; a plunger having a foot, said plunger extending through said wall of said filter housing such that said foot of said plunger resides interiorly within said wall of said filter housing; a valve mounted on said foot of said plunger; a spring operable between said exterior of said wall and said plunger urging said plunger and said foot of said plunger in a direction away from said interior of said filter housing and toward said exterior of said filter housing; said outlet of said filter housing includes a valve seat on said interior portion of said wall; and, said valve urged away from said valve seat when said plunger is depressed against the force of said spring expelling filtered water from said fountain.  
     
     
         45 . A water filtration device having an outlet fountain as claimed in  claim 44  further comprising a lever pivotally mounted on said filter housing and engaging said plunger; a fountain head rotatably secured to said plunger; and, said valve urged away from said valve seat when said lever and plunger are depressed against the force of said spring expelling water from said fountain.  
     
     
         46 . A water filtration device having an outlet fountain as claimed in  claim 44  wherein said valve is elastomeric.  
     
     
         47 . A water filtration device having an outlet fountain as claimed in  claim 45  wherein said valve is elastomeric.  
     
     
         48 . A water filtration device having an outlet fountain as claimed in  claim 44  wherein said filter housing includes a chamber and said outlet is in communication with said chamber and wherein said valve is elastomeric.  
     
     
         49 . A water filtration device having an outlet fountain as claimed in  claim 45  wherein said filter housing includes a chamber and said outlet is in communication with said chamber and wherein said valve is elastomeric.  
     
     
         50 . A water filtration device having an outlet fountain as claimed in  claim 44  wherein said plunger includes a passageway therein and wherein said outlet fountain is rotatably mounted in said passageway of said plunger.  
     
     
         51 . A water filtration device having an outlet fountain as claimed in  claim 45  wherein said plunger includes a passageway therein and wherein said outlet fountain is rotatably mounted in said passageway of said plunger and in said lever.  
     
     
         52 - 53 . (canceled)  
     
     
         54 . A water filtration device as claimed in  claim 44  wherein said filter is a carbon based filter.  
     
     
         55 - 63 . (canceled)
