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.

         19 . A water filtration device as claimed in  claim 18  wherein said plunger includes a foot and said ball valve resides over said foot.  
     
     
         20 . A water filtration device as claimed in  claim 19  wherein said foot of said plunger and said elastomeric ball valve resides within said housing.  
     
     
         21 . A water filtration device as claimed in  claim 20  further comprising a handle pivotally affixed to said housing and engaging said plunger such that when said plunger is depressed said elastomeric ball valve moves inwardly toward the center of said housing and away from said seat of said outlet.  
     
     
         22 . A water filtration device as claimed in  claim 21  wherein a spring is interposed between said plunger and said filter housing urging said elastomeric ball valve against the valve seat of said second outlet.
