Automatic Pet Drinking Fountain with Interchangeable Water Outlet Heads

The problem

Pets often ignore standing water in traditional bowls, which can lead to insufficient daily water intake. Electric drinking fountains address this by moving the water, but most models on the market produce only a single, fixed stream pattern. If a particular animal does not respond to that specific flow, the fountain fails its purpose. Additionally, many basic fountains lack integrated overflow management or convenient ways to swap out flow styles without replacing the entire pump assembly. Owners are left buying multiple devices to find a water pattern their pet prefers, creating unnecessary cost and clutter.

The solution

This patent describes an automatic pet drinking fountain that solves the single-pattern limitation through modular water outlet heads.

1. A water storage tank houses a pressurized water pump whose water inlet communicates directly with the inner space of the tank.
2. A drinking water tray sits on the top surface side of the tank. The tray includes a concave water storage pan portion nested into a recessed storage tank formed in the center of the tank lid.
3. A water guide pipe connects the system. Its bottom port links to the water outlet of the pressurized pump, passing through the accommodating cavity, while its top port protrudes above the top surface of the drinking water tray.
4. The core feature is a water outlet shower head device. Different structural forms of this device can be sleeved and/or inserted onto the top end part of the water guide pipe.
5. Swapping the shower head changes the water outlet flow form—for example, converting a direct current mushroom-shaped fountain into a flower-type sprinkling or an inclined plane drainage pattern.
6. An accommodating cavity between the water storage pan portion and the recessed storage tank holds a filter device, and overflow ports connect the tray to this cavity.

Who it is for

• Pet product brands looking to add a multi-flow electric fountain to their catalog without engineering a new pump system for every style.
• Amazon private-label sellers who need a distinct, feature-rich pet fountain that stands out from single-stream competitors in search results.
• Pet supply wholesalers distributing to retail stores where buyers want a single SKU that satisfies cats and dogs preferring different water movements.
• Veterinary clinic and boarding facility purchasers who require reliable hydration stations that can be adjusted to suit various animal temperaments.

How it works

The main parts

Operating steps

1. Fill the tank - water enters the water storage tank, submerging the pressurized water pump.
2. Power the pump - the pump draws water through its inlet and forces it upward through the water guide pipe.
3. Select the flow - the user sleeves or inserts the chosen water outlet shower head device onto the top port of the guide pipe.
4. Dispense water - water exits the shower head in the selected pattern (mushroom, flower sprinkle, or inclined drain) across the drinking water tray.
5. Recirculate - excess water passes through the overflow ports into the accommodating cavity, through the filter device, and back into the tank via the second water return outlets.

Applications

Multi-pet households

Pets in the same home do not always drink the same way: one may lap from a moving stream while another drinks only from still water at the tray edge. The interchangeable shower heads let the owner switch between the mushroom, flower-sprinkle and inclined-drain patterns and keep the one their animals actually use, without buying separate units.

Veterinary recovery rooms

Animals recovering from procedures may be hesitant to drink from unfamiliar sources. Clinic staff can swap the water outlet shower head device to present a less intimidating flow, such as a low-profile drain rather than a tall mushroom fountain. This adaptability helps encourage autonomous drinking during critical recovery periods.

Boarding kennels and catteries

Facilities housing many animals need durable, easy-to-maintain hydration stations. The nested drinking tray and accommodating cavity for a filter device simplify cleaning and water treatment. Staff can standardize the tank and pump setup while changing the shower heads based on the specific preferences of the boarded animals.

Retail pet store displays

Stores demonstrating electric fountains benefit from showing multiple flow types from a single display model. Sales staff can quickly sleeve a new shower head onto the guide pipe to show customers the mushroom, sprinkle, and drain options. This visual demonstration highlights the product’s versatility directly on the shop floor.

Where it is less suitable

• Outdoor yard use - the electrical pressurized pump and open drinking tray are designed for indoor environments where power is accessible and debris is limited.
• Large livestock watering - the tank capacity and tray dimensions described are intended for household companion animals like cats and small to medium dogs, not farm animals.
• Travel carriers - the assembled tank, pump, and protruding guide pipe make this a stationary home appliance rather than a portable travel bowl.
