Abstract
A drinking fountain for pets has a base with a water receptacle therein and a dome-shaped reserve water tank on the base. A drinking bowl on the top of the tank and a pump system for conveying water in the receptacle to the drinking bowl. Water pumped into the bowl overflows the bowl and flows down over a portion of the surface of the reserve water tank and returns to the receptacle. When the water in the receptacle falls below a predetermined level, water from the reserve tank automatically flow from the tank to the receptacle to increase the water to the prescribed level.
Claims16
A pet drinking fountain comprising
- a base and a water supply tank having a closed generally dome-shaped top disposed on the base and extending upwardly therefrom,
- a water collection area in the base disposed beneath the tank,
- a channel substantially surrounding the bottom portion of the dome-shaped tank top,
- a drinking bowl on the top of tank from which a pet may drink,
- a water pump disposed in the collection area and connected to a duct directs water in the area to the drinking bowl and to overflow the drinking bowl onto the upper portion of the tank and spill down over the outer surface of the tank and into the channel,
- and a discharge passage in the lower portion of the tank top communicating with the base enables water in the tank to flow to the collection area of the base when the water in the base falls below a predetermined level.
A device for providing drinking water to pets comprising,
- a drinking bowl for receiving water and from which pets may drink,
- a water circulation system including a water chamber separate from the bowl and means enabling water to flow from the bowl to the chamber,
- a reserve water tank for supplying additional water to the system when the water level falls below an established level in the chamber, said tank having a dome-shaped top with at least a portion thereof having a smooth surface over which the water flows from the bowl to the chamber, said tank supporting the drinking bowl at the top of the tank,
- and pump means in the system for discharging water from the chamber into the drinking bowl and from the drinking bowl the smooth surface.
A pet drinking fountain comprising
- a base and a water supply tank mounted on the base,
- a drinking bowl open at the top and formed externally on the top of the tank,
- a handle attached to the tank for carrying the tank,
- a receptacle disposed in the base,
- a duct communicating with the receptacle conveys water from the receptacle to the bowl,
- a reducer in the top of the duct creates turbulence in the bowl as water is discharged from duct to the bowl,
- an opening in the bowl permits water in the bowl to flow other than through the duct to the receptacle,
- a pump in the receptacle for continuously circulating water from the receptacle up the duct into the bowl and causes water in the bowl to flow through the opening back into the receptacle,
- and a valve system connecting the tank to the receptacle enables water from the tank to flow into the receptacle when the level of water in the receptacle falls below a predetermined level.
