A liquid dispenser may include a water tank having a wall opened at an upper side, a pump provided inside the water tank, a water supply pipe connected to the pump to transfer water, a water supply plate provided at a position higher than the wall of the water tank and having a water supply hole communicating with the water supply pipe and an upper surface over which water supplied from the water supply hole flows, and a water guide formed within the opening of the wall of the water tank and spaced apart from and below the water supply plate. The water guide may have a hole to discharge the water dropped from the water supply plate to the water tank and to filter the water.

An automatic self-cleaning and self-filling outdoor fluid feeding system for an animal, including for example a pet, includes a sink; a fluid transport system; a housing supporting the sink and containing the fluid transport system; and a control assembly configured to control the automatic self-cleaning and self-filling operations of the system.

A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.

A system for feeding farm animals comprises two milk tanks and a drawing line. The two milk tanks are configured to receive a stored full milk quantity and the drawing line comprises two drawing line portions each comprising a drain valve and each connected to one of the two milk tanks. A preparing unit is configured to prepare a liquid ration and a connecting line configured to connect the drawing line with the preparing unit. a cleaning unit comprises at least one cleaning agent container configured to receive a cleaning agent, and a cleaning agent supply apparatus configured to supply cleaning agent from the cleaning agent container to the two milk tanks. A control is configured to actuate the cleaning unit, the preparing unit, and each drain valve to guide the cleaning agent guided from one of the two milk tanks through the connecting line into the preparing unit.

A freeze-resistant watering device has a nipple or ball valve, a heat pipe, a sleeve in tight thermal contact with the nipple, a water-tight connection to a liquid containing container or supply pipe, and an outer shield enclosing an insulating space or insulation material. This device thermally couples a watering nipple or ball valve to a container or supply pipe via a thermal conduction path including bends so the nipple or ball valve maintains a temperature near that of the liquid in the container or supply pipe, and also provides a means for thawing the watering device with heat from the liquid in the container or supply pipe. The use of one or more freeze-resistant watering devices with a thermally insulated container in a watering unit with an insulated container or supply pipe provides drinking water to animals, and in particular, birds in sub-freezing and in hot weather.

A base for pet feeder and a pet feeder for eating or drinking of pets are provided. The base includes a main body portion and a plurality of adjusting mechanisms. The main body portion includes a first side and a second side, the second side is disposed opposite to the first side, and the first side is configured to contain food or water. The plurality of the adjusting mechanisms are disposed at the second side of the main body portion at intervals, each of the plurality of the adjusting mechanisms is capable of providing at least three heights. Each of the plurality of the adjusting mechanisms includes a first supporting plate and a second supporting plate. The first supporting plate includes a first part and a second part, the first part is rotatably connected to the second side.

An animal watering device is provided that is automatically fillable for providing water to animals, such as horses or other livestock. Animal watering device includes a base, a trough positioned within the base for storing water, and a water filling assembly coupled with the trough to control a water level within the trough. A ring can be positioned about an upper surface of the trough to protect the upper surface of the trough. A disc can be positioned within the trough to cover a portion of water filling assembly positioned within the trough, while allowing water to flow through the disc.

A watering tank circulating assembly includes a frame submerged in a livestock watering tank. A fluid pump is coupled to the frame to circulate the water when the fluid pump is turned on. In this way the fluid pump inhibits the water from freezing. A heating coil is coupled to the frame to heat the water when the heating coil is turned on, thusly inhibiting the water from freezing. A thermostatic switch is coupled to the frame and each of the fluid pump and the heating coil is electrically coupled to the thermostatic switch. The thermostatic switch turns on each of the fluid pump and the heating coil when the temperature of the water drops below a trigger temperature. Additionally, the thermostatic switch turns off each of the fluid pump and the heating coil when the temperature of the water rises about the trigger temperature.

An automatic animal watering assembly includes a base that has a bowl section therein and a receiver section. A container is removably inserted into the receiver section of the base. The container contains water and the container releases the water into the bowl section. The container has an opening extending through a top end of the container for filling the container. A plug is movably positioned within the container. The plug is positionable in a closed position and an open position. A lid is hingedly coupled to the top end of the container. A lever is pivotally coupled to the container and the plug rests on the lever. The lever lifts the plug when the lever is lifted and the lever lowers the plug when the lever is lowered. The lever is in mechanical communication with the lid such that the lid lowers and lifts the lever.

A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.
