Benefits of technology

"The patent describes a single-use faucet-mounted water filtration device that is convenient, cost-effective, and easy to use. The device is made with a minimum of components, making it compact and portable. It can be used in both the kitchen and bathroom sink, and is small in size. The device includes a filter housing with a chamber containing the filter, which can be activated carbon or other filter media. The filter is non-removable and disposable, making it easy to use in different locations. The device is easy to install and remove, and can be used with a variety of filter media. The filter has a useful life of up to 300 gallons, depending on the type of filter and the sizing of the water flow paths. The device is small and portable, making it convenient for travel. The front housing is non-removably affixed to the filter housing and the device includes a housing end cap, ultrasonically welded to the filter housing, and a continuous periphery welded to the filter housing. The device also includes a spring, interposed between the plunger and the filter housing, and a directional valve for controlling the flow out of the second outlet. The device also includes a sensor to indicate the position of the filter."

Problems solved by technology

The device is of uni-body construction and has no removable or replaceable parts yet provides long life operation.

first embodiment

[0105] Referring to FIG. 1, an exploded assembly view of the water filtration device 100, the various components of the single-use faucet mounted water filter are shown. Filter 113 is illustrated having a longitudinal bore 129 therethrough. Filter 113 is illustrated without a filter pre-wrap in this view but such a pre-wrap 495 is specifically within the scope of this invention and is illustrated in FIGS. 4G and 4H. The filter is preferably a carbon block but may be a fiber bundle or granular activated carbon. Further, the carbon block may include bacteriastic materials, ion exchange resins and zeolites to assist in its filtration activity. End caps 114 and 115 are affixed to said filter with a hot melt adhesive applied to the entire mating surfaces of end caps 114 and 115 including but not limited to the dowel portions thereof such as dowel 130A on right end cap 130. Once filter 113 is affixed to end caps of filter 114, 115, the subassembly is inserted into the filter housing 101. ...

second embodiment

[0152]FIG. 18 is a perspective view 1800 of the front housing of the FIG. 18 employs reference numerals like FIG. 4. FIG. 18A is a cross-sectional view taken along the lines 18A-18A of FIG. 18. Reference numeral 1801 indicates the wall to which the collar lock 1505 is welded and reference numeral 1804 indicates the floor upon which the collar lock 1804 sits at the time it is welded. Mold recesses 1802 are from the molding process. Groove or recess 1816 receives the seal from the valve 108. Cavity 1831 receives the valve 108. Referring to FIG. 18A, stop 1807A is illustrated which engages ridges 602 on valve 108. Stop 1807A is also illustrated in FIG. 18B, a cross-sectional view taken along the lines 18B-18B of FIG. 18. Tapered bore 1812 is illustrated by the circular lines in FIG. 18A.

[0153] Bore 1822 includes stepped portions 1813 and 1829. Inlet 1808 is shown leading to valve cavity 1831. Outlet 1814 and outlet 1809 are also shown in FIG. 18A. When valve 108 is positioned as illus...

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.

Description

[0001] This patent application claims priority to, and is a divisional of, copending patent application Ser. No. 10 / 613,950. This patent application claims priority of provisional patent application Ser. No. 60 / 438,457 filed Jan. 8, 2003 and provisional patent application No. 60 / 409,042 filed Sep. 9, 2002.FIELD OF INVENTION [0002] The field of the invention is water filtration devices. BACKGROUND OF THE INVENTION [0003] The demand for pure water continues to grow rapidly due to increasing concerns about the quality and safety of tap water, the popularity of water as a beverage (instead of soda and alcohol) and the growing awareness that most people do not drink enough water as prescribed by the medical community. [0004] Water is supplied from municipal water systems (many of which are aging), private water systems and wells in the United States. Frequently, this water has poor taste, particulates, unwanted odors and in many cases contaminants contained in it. Municipal water is comm...
