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 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.

A pet water dispenser may include a water tank having a space to store water and an upper opening, a pump installed in the space, a water supply pipe to transfer water discharged from the pump, and a water supply plate to which water is supplied from the water supply pipe. The water tank may include a wall defining the space and a water tank base supporting the wall from below. An upper end of the wall may be smaller than a lower end of the wall, as the wall may be inclined inward from the lower end to the upper end.

A pet water dispenser may include a water guide and filter surrounding a pump such that water is well-circulated throughout the pet water dispenser. The pet water dispenser may include a water tank, a water supply pipe to which water discharged from the pump is transferred, and a water supply plate having an upper surface over which water flows. The water guide may catch water falling from the upper surface to discharge the water back to the water tank.

A liquid dispenser may include a container or tank having an upper opening and in which water is stored, a pump provided in the container, a water supply pipe through which water discharged from the pump is transferred, a water supply plate having an upper surface over which water flows, a container support or base provided below the container, and a thermoelectric element provided in the container support to cool the bottom plate of the container.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

A pet-feeder device is provided. The pet-feeder device may include a casing, a printed circuit board, at least one compartment, at least one mixer, and a tray. The mixer may be located below at least one compartment. The tray may include at least one bowl. The tray may be located below the mixer.

The present disclosure relates to a water supplier for a pet and a control method thereof, that is, a water supplier for a pet that operates a thermoelectric element by sensing the temperature of water stored in a water tub through a water temperature sensor, operates a warning unit by sensing the level of the water stored in a water tub through a water level sensor, operates a pump by sensing a pet within a predetermined distance range through a proximity sensor, and cuts power or keeps the inclination of a water dispenser horizontal by sensing the inclination of the water tub through a gyro sensor, and a method of controlling the water supplier.

In one aspect, the present disclosure is directed to preventing or lessening ice in remote water tanks. The remote water tanks can include a body at least partially defining a chamber that receives a liquid and having an open top portion that provides one or more animals access to the liquid. Further, a heat exchanger can be at least partially received within the chamber, and can receive a thermal transfer fluid that is circulated therethrough to maintain a temperature of the liquid in the chamber. Also, an external heat collector can be in fluid communication with the heat exchanger to transfer solar or other heat to the thermal transfer fluid as the thermal transfer fluid is circulated therethrough.

A livestock grazing control robotic system provides a movable livestock enclosure than can travel over uneven terrain allowing livestock to graze over different areas, enabling rotational grazing in a cash crop farmland during non-crop time periods. The system includes an enclosure or pen defined by a fencing mechanism. The fencing mechanism is supported by a movable chassis that includes a drivetrain system. The fencing mechanism includes a ground-clearance portion that flexibly covers the area between the chassis and the uneven ground, preventing animals from entering or exiting the enclosure and that can be raised and lowered on command to enable moving of the enclosure. The fencing mechanism may hold water for watering livestock. The system further includes a control module and a power supply that enable autonomous movement of the enclosure according to a grazing plan. The system may receive water and be towed by a water delivery vehicle.
