AVICULTURE; APICULTURE; PISCICULTURE; FISHING; REARING OR BREEDING ANIMALS, NOT OTHERWISE PROVIDED FOR; NEW BREEDS OF ANIMALS ## Abstract Disclosed is a watering device for animals and a method of producing the same, including a base unit defining a bowl portion, a housing portion disposed in the base unit and including an inlet port and an outlet port in fluid communication with the bowl portion, a dispensing unit proximate the outlet port to dispense water from the housing portion to the bowl portion via the outlet port such that water flows around the bowl portion to the housing portion via the inlet port, and a filtering unit interposed between the outlet port and the inlet port to filter the water flowing from the bowl portion to the housing portion via the inlet port. ## Claims ### Claim 1 A watering device for animals, comprising: a base unit defining a wall and an interior bowl portion for containing a volume of water; a housing portion disposed in the base unit and extending into the interior bowl portion, the housing portion comprising an inlet port and an outlet port, wherein the inlet and outlet ports are in fluid communication with the interior bowl portion and are disposed on opposing sides of the housing portion; a dispensing unit communicating with the outlet port to dispense water from the housing portion into the bowl portion via the outlet port proximate the wall, such that water continuously circulates around the housing portion within the bowl portion to the inlet port in a radial pattern; and a filtering unit disposed between the inlet port and the outlet port to filter the water flowing from the interior bowl portion back to the housing portion via the inlet port. ### Claim 2 (depends on 1) The watering device of claim 1, wherein: the housing portion includes an island located proximate a center of the bowl portion, and a neck portion extending between an inner wall of the bowl portion and the island, the neck portion having opposing sides to define the inlet port and the outlet port, respectively; and the dispensing unit is configured to dispense water through the outlet port at a position substantially adjacent to the bottom surface of the bowl portion while the dispensing unit is in operation. ### Claim 3 (depends on 2) The watering device of claim 2, wherein the island includes an aperture to receive and accommodate a power cord for the dispensing unit. ### Claim 4 (depends on 2) The watering device of claim 2, further comprising: a detachable cover forming a top surface of the island, a first grate adjacent the inlet port, and a second grate adjacent the outlet port. ### Claim 5 (depends on 2) The watering device of claim 2, wherein the dispensing unit is a water pump. ### Claim 6 (depends on 5) The watering device of claim 5, further comprising: a sliding member slidably received adjacent the outlet port and in fluid communication with the water pump, wherein the sliding member contains an aperture configured to direct the pumped water through the outlet port. ### Claim 7 (depends on 6) The watering device of claim 6, wherein the aperture on the sliding member is located adjacent to the bottom surface of the watering bowl. ### Claim 8 (depends on 1) The watering device of claim 1, wherein the base unit is generally circular. ### Claim 9 (depends on 8) The watering device of claim 8, wherein the bowl portion is also generally circular. ### Claim 10 (depends on 9) The watering device of claim 9, wherein a bottom surface of the bowl portion is sloped to encourage the flow of water around the housing portion from the outlet port to the inlet port while the dispensing unit is in operation. ### Claim 11 (depends on 1) The watering device of claim 1, wherein the filtering unit defines a diaphragm-like member. ### Claim 12 (depends on 1) The watering device of claim 1, wherein the filtering unit is resides adjacent to the inlet port within the housing portion. ### Claim 13 (depends on 1) The watering device of claim 1, wherein the filtering unit is secured in place by mating slots disposed within the housing portion. ### Claim 14 A method of delivering water to animals, comprising the steps of: providing an animal watering device, the device comprising: a base unit defining a wall and an interior bowl; a housing portion in the base unit and extending into the interior bowl portion, wherein the housing portion comprises an inlet port and an outlet port, and wherein the inlet and outlet ports are in fluid communication with the interior bowl portion and are disposed on opposing sides of the housing portion; a dispensing unit communicating with the outlet port to dispense water from the housing portion into the interior bowl portion via the outlet port; and a filtering unit disposed between the inlet port and the outlet port; placing a volume of water into the base unit; activating the dispensing unit to cause the volume of water to circulate continuously from the outlet port, around the housing portion within the interior bowl portion, and to the inlet port in a radial pattern, and then through the filtering unit; and delivering the filtered water back into the interior bowl portion via the outlet port. ### Claim 15 (depends on 14) The method of claim 14, wherein: the housing portion defines an island located proximate a center of the bowl portion, and a neck portion extending between the wall of the bowl portion and the island, the neck portion having opposing sides to support the inlet port and the outlet port, respectively; the dispensing unit pumps water through the outlet port at a location substantially adjacent to the bottom surface of the bowl portion; and causing the water to circulate from the outlet port to the inlet port means causing water to circulate continuously around the island in a generally circular manner. ### Claim 16 (depends on 15) The method of claim 15, wherein: the dispensing unit is a pump; the island includes an aperture to receive and accommodate a power cord for the dispensing unit; and activating the dispensing unit means using the power cord to provide power to the animal watering device. ### Claim 17 (depends on 15) The method of claim 15, wherein the animal watering device further comprises: a detachable cover forming a top surface of the island, a first grate adjacent the inlet port, and a second grate adjacent the outlet port; and wherein the neck portion also includes a cover, and a bottom surface of the bowl portion is sloped to encourage the flow of water around the island portion from the outlet port to the inlet port while the dispensing unit is in operation. ### Claim 18 (depends on 17) The method of claim 17, wherein: the filtering unit resides adjacent to the inlet port within the neck portion.
