A liquid dispenser is described, having a tank configured to deliver and present a liquid in a drink basin within a tray base. The liquid may be a liquid bait for population control of small animals To reduce evaporation and liquid waste, the tray base may be partially covered by a tray top. A spill basin may surround the drink basin, and may be configured so that tilting or inverting the liquid dispenser drains a liquid from the spill basin and drink basin back into the tank.

Disclosed is a pet water dispenser, including: a drinking tray, disposed above a water storage tank; and a water pump, configured to pump drinking water in the water storage tank to the drinking tray.

A watering tank circulating assembly includes a frame that is submerged in a livestock watering tank. A fluid pump is coupled to the frame to circulate the water in the livestock watering tank 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 animal feeder comprising a housing, at least one food receptacle coupled to the housing, configured to receive and store food and comprising an inlet opening for receiving food and an outlet opening for releasing food, at least one supplement receptacle coupled to the housing, configured to receive and store at least one supplement, a food dispensing mechanism coupled to the at least one food receptacle, configured to dispense food, a supplement dispensing mechanism coupled to the at least one supplement receptacle and configured to dispense supplement from the at least one supplement receptacle, a control system coupled to the housing and connected to the food and supplement dispensing mechanisms, the control system configured to control the food and supplement dispensing mechanisms so that a desired amount of food and supplement are dispensed, and a power source coupled to the control system and the food and supplement dispensing mechanisms.

The application belongs to the technical field of pet equipment, in particular to a pet water dispenser, comprising a filter, a water pump, a drinking dish and a water storage tank with a water storage space; the drinking dish is provided with a water storage sink and a first through hole communicating with the water storage sink, the water pump and the filter are both installed on the water storage tank, and the drinking dish covers the water storage tank; a water inlet of the water pump is communicated with the water storage space, a water outlet of the water pump is communicated with the water storage sink, and the first through hole is communicated with the water storage space through the filter; the water pump, the water storage sink, the first through hole, the filter and the water storage space form a circulating filtration loop for drinking water.

A water feeder filter water feeder includes a water storage tank and a water drinking portion. The filter supplies and returns water from the water storage tank to the water drinking portion. The filter is detachably provided between the water storage tank and the water drinking portion and passes the water from an upper surface side to a lower surface side of the filter. The filter includes a filter tray with a bottom wall having a water passing aperture and an outer peripheral wall. An internal filter medium is in the filter tray. A top covering filter medium covers an upper end opening of the filter tray. A partition wall of the filter tray is formed with a lower side is positioned inner than an upper side when viewed from each chamber. The outer peripheral wall is formed with a lower side is positioned inner than an upper side.

Animal drinking troughs have pressure reducers for reducing the higher pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. For various reasons, it is desired to change the reduced pressure. This takes place by adjustment of the pressure reducers. It is known to undertake such an adjustment with compressed air. This requires a separate compressed air source and a corresponding pipe system. The invention makes provision to adjust the pressure reducer hydraulically by means of the higher pressure of the liquid of the liquid supply. The energy required for adjusting the pressure reducers thereby provides the liquid pressure of the liquid supply. As a result, the pressure reducers according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers is not required.

An apparatus for the treatment of drinking water contained in a vessel is disclosed. The apparatus comprises a housing, a drinking water inlet and a drinking water outlet. The apparatus also includes a pump operable to pump drinking water from the water inlet to the water outlet, wherein the water outlet and pump are configured to dispense drinking water generally upwards from the water outlet below a surface of the drinking water to cause a continuing disturbance in a surface of the drinking water contained in the vessel. In one example, the apparatus is used to reduce algae in the water. In another example, the apparatus is used to increase the oxygen content in the water.

A method and apparatus for delivering sanitized drinking water to a poultry or other animal husbandry facility with water supplied from either a potable or non-potable source. In the case of a non-potable water source, ozone and antimicrobial copper or copper alloy are employed as primary and secondary sanitizing agents to eliminate chemical and biological drinking water contaminants. Ozone gas is generated onsite and serves as the primary sanitation agent prior to distribution of water to nipple drinker conduits within the facility. In the case of a potable water source, water is delivered directly to the drinking water distribution system. In either case, at least one conduit is filled with a woven mesh of antimicrobial copper to perform as a passive sanitation agent to inhibit microbial propagation and prevent development of biofilm within a nipple drinker system during periods of low flow and high temperatures. In the case of non-potable water source, as animals mature and consume more water, increasing concentrations of residual ozone clean the copper/copper alloy mesh surface and sanitize exposed nipple drinker actuator pins.

A livestock water fountain comprises a first water chamber, a water inlet near the bottom of the first water chamber, and a thermostat in the first water chamber position above the inlet adjacent a preset low-water level in the chamber so as to measure the temperature of the water near the surface of the water. The fountain maybe divided into dual chambers with a wall having a lower passageway for fluid communication which can be plugged to limit water to one of the chambers when water consumption decreases in cold weather.
