    Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

    Abstract: An interconnection scheme between a filter cartridge and its corresponding manifold whereby a magnetic shear force is introduced to remove a blocking mechanism that would otherwise prohibit attachment. The magnetic shear force may also be employed to activate or deactivate a switch or valve, or engage or disengage an engagement mechanism relative to other components upon interconnection. The magnetic shear force is generated by complementary correlated magnet structures moved into close proximity to one another. The interconnection scheme may be a linear or rotational attachment of the filter cartridge with respect to the manifold. A valve assembly utilizing magnetic shear force may be employed to activate a bypass action between a manifold ingress port and egress port, thereby allowing water to flow when a filter cartridge is removed from the manifold and directing water to the filter cartridge when the valve assembly is activated.

    Abstract: A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

    Abstract: A gravity-fed filtration system interconnection structure comprising a reservoir for receiving ingress fluid, the reservoir having a bottom surface with a recess for receiving a filter cartridge body, and an opening for filtered fluid egress to a second, dispensing reservoir. A carrier or shuttle having a magnet disposed within or connected to the carrier is adjacent to the reservoir recess and connected to a sluice gate valve which normally blocks the opening to the second reservoir. The interconnection structure further includes a filter cartridge having a housing body, and a filter magnet disposed within or fixedly connected to the housing body. The carrier is normally biased in a first position, such as a closed position, and is moveable between the first position and a second (open) position, and the filter magnet and the carrier magnet are interconnected via magnetic communication upon insertion of the filter cartridge into the reservoir recess, such that upon relative movement of the filter magnet and carrier magnet into an alignment position, the carrier moves to the second position as a result of the magnetic communication. In one embodiment, the carrier translates axially upwards within a channel in the reservoir recess wall as a result of the magnet communication. In another embodiment, the carrier shifts radially in a direction perpendicular to the longitudinal axis of the filter cartridge body. In still another embodiment, the carrier rotates about the longitudinal axis of the filter cartridge. The filter magnet polarity transitions are aligned with the carrier magnet polarity transitions such that a shear force or rotational force is generated between the magnets when the filter cartridge is inserted within the reservoir recess, causing the carrier to move from the first position to the second position.

    Abstract: A filter for gravity-fed applications, having filter media with a hollow center, the filter being generally prone to a degradation or cessation in fluid flow due to air entrapment or air lock within the filter housing cavity, which develops during filtering. A diffuser element is introduced to pierce the entrapped air bubble, the diffuser element being an elongated structure connected to the filter housing top end cap and extending through the entrapped air bubble to the filter media.
