Abstract

A pet water fountain is described comprising a bowl for holding an aqueous drinking fluid. The pet water fountain includes a housing configured to cover a portion of the bowl and have a fluid reservoir. The pet water fountain includes a rotatable cone positioned within the housing, the cone tapering outwardly from a bottom end to a top end, the cone bottom end having a fluid inlet to allow the passage of fluid from the bowl through the inlet and into the interior of the cone, the cone top end being in fluid communication with the housing fluid reservoir. The pet water fountain includes a filter ring coupled to the cone top end, the filter ring having an exterior housing and a filtering media positioned within the exterior housing, and an electric motor coupled to the rotatable cone for rotatably driving the rotatable cone.

First claim

The invention claimed is:

1. A pet water fountain comprising:
a bowl for holding an aqueous drinking fluid;
a housing configured to cover a portion of the bowl and have a fluid reservoir;
a rotatable cone positioned within the housing, the cone tapering outwardly from a bottom end to a top end, the cone bottom end having a fluid inlet to allow the passage of fluid from the bowl through the inlet and into the interior of the cone, the cone top end being in fluid communication with the housing fluid reservoir;
a filter ring coupled to the cone top end, the filter ring having an exterior housing and a filtering media positioned within the exterior housing, the exterior housing has a lower housing and an upper housing, and wherein the lower housing includes an inboard wall and an outboard wall spaced from the inboard wall to define a channel therebetween, wherein the inboard wall has a plurality of water entrance openings, and wherein the outboard wall has a plurality of water exit openings, wherein the filtering media is positioned within the channel, and
an electric motor coupled to the rotatable cone for rotatably driving the rotatable cone.

2. The pet water fountain of claim 1 wherein the electric motor is positioned outside the bowl.

3. The pet water fountain of claim 1 wherein the filter ring is removably coupled to the rotatable cone.

4. The pet water fountain of claim 1 wherein the upper housing is removably coupled to the lower housing.

5. The pet water fountain of claim 1 wherein the upper housing has a central opening, and wherein the upper housing has a plurality of inwardly extending projections.

6. The pet water fountain of claim 1 wherein the filtering media is a carbon material.

7. A pet water fountain for dispensing an aqueous drinking fluid, comprising: a bowl having a drinking portion and an interior portion; a housing at least partially covering the interior portion; a fluid reservoir in fluid communication with the bowl; a liquid pump in fluid communication with the bowl and the reservoir, the liquid pump including a cone-shaped tube coupled to an electric motor for rotation of the cone-shaped tube, the cone-shaped tube having a lower end positioned within the bowl and an upper end positioned adjacent the fluid reservoir, and a water filter ring coupled to the upper end of the cone-shaped tube, the water filter ring having an exterior housing with an interior wall with a plurality of water entrance openings and an exterior wall with a plurality of water exit openings, the water filter ring also having a filtering media positioned within the exterior housing between the interior wall and the exterior wall.

8. The pet water fountain of claim 7 wherein the water filter ring is removably coupled to the cone-shaped tube.

9. The pet water fountain of claim 7 wherein the exterior housing has a lower housing and an upper housing, and wherein the lower housing includes the interior wall and the exterior wall, and wherein the interior wall and the exterior wall define an annular channel in which the filtering media is positioned.

10. The pet water fountain of claim 9 wherein the upper housing is removably coupled to the lower housing.

11. The pet water fountain of claim 10 wherein the upper housing has a central opening, and wherein the upper housing has a plurality of inwardly extending projections.

12. The pet water fountain of claim 7 wherein the filtering media is a carbon material.

13. A pet water fountain comprising,
a water bowl;
a housing coupled to the water bowl;
a rotating cone coupled to the housing, the rotating cone having a water inlet extending through a lower portion of the rotating cone and a water outlet at an upper portion of the rotating cone;
a water filter coupled to the upper portion of the rotating cone, the water filter having a filter housing and a filtering media positioned within the filter housing,
wherein the water filter has a lower housing and an upper housing, and wherein the lower housing includes an inboard wall and an outboard wall spaced from the inboard wall to define a channel therebetween, wherein the filtering media is positioned within the channel, wherein the inboard wall has a plurality of water entrance openings, and wherein the outboard wall has a plurality of water exit openings, and
an electric motor coupled to the rotating cone for rotational movement of the rotating cone, the electric motor being positioned outside the water bowl.

14. The pet water fountain of claim 13 wherein the water filter is removably coupled to the rotating cone.

15. The pet water fountain of claim 13 wherein the upper housing is removably coupled to the lower housing.

16. The pet water fountain of claim 15 wherein the upper housing has a central opening, and wherein the upper housing has a plurality of inwardly extending projections.

17. The pet water fountain of claim 13 wherein the filtering media is a carbon material.
