Abstract
A gravity-fed filtration system and method of permitting fluid flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system. The method comprises providing a filter cartridge having a filter magnet, a holding reservoir for filtered fluid, and a first reservoir having a recess receiving cavity in a bottom surface thereof for receiving ingress fluid. Upon inserting the filter cartridge into the recess receiving cavity and moving the filter magnet to be in magnetic communication with the carrier magnet, a magnetic field force moves the carrier magnet from a first position which blocks fluid flow, to a second position which allows fluid flow to the holding reservoir.
Claims20
A filtration system for gravity-fed applications comprising:
- a first reservoir for receiving ingress fluid, said first reservoir having a recess cavity including an aperture;
- a filter cartridge assembly receivable within said recess cavity to form a fluid-tight seal with said first reservoir, said filter cartridge assembly having a housing body, a filter media, and a filter magnet disposed within, connected to, or proximate said housing body;
- a second reservoir in fluid communication with said first reservoir, such that said second reservoir receives filtered fluid from said filter cartridge assembly through said recess cavity aperture;
- and
- a carrier proximate said recess cavity and moveable between a first position and a second position, said carrier comprising a carrier magnet;
- wherein a magnetic field force is generated between said filter magnet and said carrier magnet upon insertion of the filter cartridge assembly into said recess cavity, said magnetic field force causing said carrier to move from said first position, blocking fluid flow, to said second position, allowing for fluid flow, to said second reservoir.
A filter cartridge for use in a gravity-fed filtration system, the filter cartridge comprising:
- a housing having a body with a sidewall, a top end portion, a bottom end portion, and a longitudinal axis;
- a filter media disposed within the housing body;
- and
- a filter magnet disposed within or connected to said housing body sidewall proximate said bottom end portion.
