AVICULTURE; APICULTURE; PISCICULTURE; FISHING; REARING OR BREEDING ANIMALS, NOT OTHERWISE PROVIDED FOR; NEW BREEDS OF ANIMALS ## Abstract A water filtering pet bowl assembly includes a bowl including a raised drinking water location, a bottom to-be-pumped water location having a raised platform, and a central channel between the raised drinking water location and the bottom to-be-pumped water location, such that, in an in-use operation of the water filtering pet bowl assembly, water flows by gravity flow from the raised drinking water location, through the central channel, and to the bottom to-be-pumped water location; a filter assembly positioned above the bottom to-be-pumped water location; and a pump coupled with the filter assembly and positioned in the bottom to-be-pumped water location; wherein, in the in-use operation of the water filtering pet bowl assembly, a base of the filter assembly is positioned on the raised platform. ## Claims ### Claim 1 A water filtering pet bowl assembly comprising a bowl including a raised drinking water location, a bottom to-be-pumped water location having a raised platform, and a central channel between the raised drinking water location and the bottom to-be-pumped water location, such that, in an in-use operation of the water filtering pet bowl assembly, water flows by gravity flow from the raised drinking water location, through the central channel, and to the bottom to-be-pumped water location; a filter assembly positioned above the bottom to-be-pumped water location; and a pump coupled with the filter assembly and positioned in the bottom to-be-pumped water location; wherein, in the in-use operation of the water filtering pet bowl assembly, a base of the filter assembly is positioned on the raised platform, wherein an inlet of the pump is positioned lower in the bowl than a bottom of the raised drinking water location, such that the pump is prevented from running dry in the in-use operation of the water filtering pet bowl assembly. ### Claim 2 (depends on 1) The water filtering pet bowl assembly of claim 1, wherein, in the in-use operation of the water filtering pet bowl assembly, the raised platform and the base of the filter are above a water level in the bottom to-be-pumped water location. ### Claim 3 (depends on 1) The water filtering pet bowl assembly of claim 1, wherein, in the in-use operation of the water filtering pet bowl assembly, the pump and the filter assembly recirculate water from the bottom to-be-pumped water location to the raised drinking water location. ### Claim 4 (depends on 1) The water filtering pet bowl assembly of claim 1, wherein the bowl is a unitary ceramic piece. ### Claim 5 A water filtering pet bowl assembly comprising a bowl including a raised drinking water location, a bottom to-be-pumped water location having a raised platform, and a central channel between the raised drinking water location and the bottom to-be-pumped water location, such that, in an in-use operation of the water filtering pet bowl assembly, water flows by gravity flow from the raised drinking water location, through the central channel, and to the bottom to-be-pumped water location; a filter assembly positioned above the bottom to-be-pumped water location; and a pump coupled with the filter assembly and positioned in the bottom to-be-pumped water location; wherein, in the in-use operation of the water filtering pet bowl assembly, a base of the filter assembly is positioned on the raised platform, wherein the raised platform is made of two segments each including a central base extending in a curved manner to rounded ends at each end of the central base. ### Claim 6 (depends on 5) The water filtering pet bowl assembly of claim 5, wherein between one set of the rounded ends is an electrical cord slot for receiving an electrical cord for the pump, and wherein between another set of the rounded ends is a portion of the central channel. ### Claim 7 A water filtering pet bowl assembly comprising a bowl including a raised drinking water location, a bottom to-be-pumped water location having a raised platform, and a central channel between the raised drinking water location and the bottom to-be-pumped water location, such that, in an in-use operation of the water filtering pet bowl assembly, water flows by gravity flow from the raised drinking water location, through the central channel, and to the bottom to-be-pumped water location; a filter assembly positioned above the bottom to-be-pumped water location; and a pump coupled with the filter assembly and positioned in the bottom to-be-pumped water location; wherein, in the in-use operation of the water filtering pet bowl assembly, a base of the filter assembly is positioned on the raised platform, wherein a border portion is positioned above the raised platform, such that the base of the filter assembly is prevented from outward movement by the border portion. ### Claim 8 A water filtering pet bowl assembly comprising a bowl including a raised drinking water location, a bottom to-be-pumped water location having a raised platform, and a central channel between the raised drinking water location and the bottom to-be-pumped water location, such that, in an in-use operation of the water filtering pet bowl assembly, water flows by gravity flow from the raised drinking water location, through the central channel, and to the bottom to-be-pumped water location; a filter assembly positioned above the bottom to-be-pumped water location; and a pump coupled with the filter assembly and positioned in the bottom to-be-pumped water location; wherein, in the in-use operation of the water filtering pet bowl assembly, a base of the filter assembly is positioned on the raised platform, wherein the central channel includes two tapered sidewalls each tapering from an upper wider portion at a top surface down to a lower narrower portion at a bottom of the central channel. ### Claim 9 (depends on 8) The water filtering pet bowl assembly of claim 8, wherein each tapered sidewall includes a respective top border segment thereabove, the top border segment extending down to a respective front border segment. ### Claim 10 (depends on 9) The water filtering pet bowl assembly of claim 9, wherein a nozzle cover is positioned over the central channel. ### Claim 11 (depends on 10) The water filtering pet bowl assembly of claim 10, wherein the top border segments are tapered in a front-to-back manner, such that a distance between the top border segments is wider nearer the bottom to-be-pumped water location and the distance between the top border segments is narrower nearer the raised drinking water location. ### Claim 12 (depends on 11) The water filtering pet bowl assembly of claim 11, wherein the nozzle cover includes a top portion that is tapered in a manner corresponding to the front-to-back manner such that the cover is prevented from movement in a frontward manner. ### Claim 13 (depends on 10) The water filtering pet bowl assembly of claim 10, wherein the nozzle cover includes a nozzle hole for a nozzle of the filter assembly to pass therethrough. ### Claim 14 (depends on 10) The water filtering pet bowl assembly of claim 10, wherein the nozzle cover includes a bottom end that does not contact a bottom of the bowl.
