ABSTRACT:
A water purification device includes a housing having a base portion and a generally-cylindrical cup-shaped cap removably secured thereto. An input fluid channel in the base portion communicates with one end of the chamber defined by the cup and an outlet fluid channel communicates with that chamber end. A filter cartridge disposed within the cap has a conduit that extends between its opposite end walls. Filter material surrounds the conduit. An inlet opening in the cartridge is positioned to communicate with the input fluid channel so as to permit water to flow through the filter material. An outlet opening in the cartridge is arranged to communicate from the filter material to the other end of the aforementioned conduit remote from said outlet channel. The conduit other end is positioned to communicate to the outlet channel. A valve is included in an extension of the base portion in order selectively to control the distribution of water as between an outlet passage and the inlet channel. The valve itself has a bore and corresponding stem which are longitudinally tapered, a recess cut longitudinally into the stem for permitting fluid to flow from an inlet port outwardly from one end of the stem, an inset cut laterally into the stem opposite the aforesaid recess, and a resilient sealing member disposed in a groove cut laterally into the stem and surrounding the inset exclusive of the recess.
