Water treatment cartridge with sealable inlet and outlet to prevent leaks

A water treatment cartridge for use with an assembly head comprising a pair of valves for controlling the flow of water therethrough, the water treatment cartridge comprising an inlet and an outlet both in communication with the valves and configured to automatically close upon a removal of the water treatment cartridge from the assembly head, thereby minimizing water leaks and contamination to the water treatment cartridge, the water treatment cartridge comprising:

• a connector member detachably coupled to the assembly head and comprising a cartridge body comprising an inlet and an outlet;
• a first generally circular dividing wall coupled to an interior of the cartridge body and positioned around the outlet;
• an inner end cover coupled to the interior of the cartridge body, the inner end cover comprising an outer top face, a second generally circular dividing wall coupled to both the outer top face and an interior wall of the first generally circular dividing wall, and a hole disposed on the outer top face within the second generally circular dividing wall;
• a pair of valve stems disposed within the cartridge body and configured to be operably connected to the assembly head, the pair of valve stems comprising a first valve stem disposed within the inlet and a second valve stem disposed within the outlet, each valve stem of the pair of valve stems comprising a head portion extending out of the inlet or outlet, a rod portion enclosed within the inlet or outlet, and a tail portion positioned within the cartridge body;
• and
• a pair of driving springs coupled to the pair of valve stems, the pair of driving springs comprising a first driving spring in contact with the tail portion of the first valve stem and inner end cover and a second driving spring in contact with the tail portion of the second valve stem and inner end cover, the first driving spring in contact with a first portion of the outer top face of the inner end cover, the second driving spring housed within the second generally circular dividing wall and in contact with a second portion of the outer top face of the inner end cover;
• wherein the head portions of both the first and second valve stems are configured to contact the assembly head to compress the first and second driving springs, thereby removing the tail portions of the first and second valve stems from the inlet and outlet to permit water to flow therethrough;
• wherein the first and second valve stems are configured to be detached from the assembly head to decompress the first and second driving springs, thereby permitting the tail portions of the first and second valve stems to seal both the inlet and outlet, thereby minimizing water leaks and contamination to the water treatment cartridge.
