A shutoff switch for dispensing mixed beverages is presented. The shutoff switch includes a syrup inlet receiving syrup and a syrup outlet dispensing the syrup to a pump. The shutoff switch also includes a water inlet receiving water, and a water outlet dispensing the water to a either the pump or a dispensing point. Two distinct inlets and outlets for syrup and water prevent the syrup and water being mixed in the shutoff switch. The shutoff switch further includes a pressure responsive member that deforms based on pressure changes in the shutoff switch. When the deformation of the pressure responsive member reaches a threshold, an electrical gate in direct communication with the pressure responsive member opens, turning of a pump of the beverage dispensing system. Valves in either chamber of the shutoff switch can also be used as a redundant mechanical way to stop flow in the system.

The present invention provides a beverage preservation keg with an adjustable beer tap, including a shell, an inner container, and a gas-liquid control device; the inner container includes an upper gas storage chamber and a lower beer storage chamber; the gas-liquid control device includes a keg spear, a dispenser and a beer discharge pipe; the keg spear matches and communicates with the gas storage chamber and the beer storage chamber, and the top end of the keg spear matches and is connected to the dispenser; the dispenser is connected to the matching beer discharge pipe. The present invention has the function of adjusting the beer flow rate, and the keg spear is provided with a pressure relief valve, which eliminates the need for a gas tube and a separate pressure relief valve to connect the keg spear to the gas storage chamber in series.

A water purifier that includes: a filter unit that is configured to purify water; a cooling unit that is configured to cool water purified by the filter unit using cooling water; a water discharge unit that is configured to discharge water cooled by the cooling unit; a cold water flow path that couples the cooling unit to the water discharge unit and through which water cooled by the cooling unit passes; a cold water discharge valve that is coupled to a first side of the cooling unit and that is configured to control water flow inside the cold water flow path; and a check fitting unit that is coupled to a first side of the water discharge unit and that is configured to block pressure change inside the cold water flow path is disclosed.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

A beverage dispenser includes a gas infusion device configured to infuse a gas into a base liquid to form a gas-infused liquid, a mixing chamber configured to mix the gas-infused liquid and a concentrate to thereby form a reconstituted beverage, a first flow control configured to decrease pressure of the gas-infused liquid prior to mixing with the concentrate, and a second flow control configured to decrease pressure of the concentrate prior to mixing with the gas-infused liquid. A restrictor device downstream from the mixing chamber and configured to apply backpressure on the concentrate and the gas-infused liquid, and a dispensing valve is configured to dispense the reconstituted beverage.

A water purifier that includes: a main body including: a filter unit, a cooling unit, and a heating unit; a first water tube through which water purified by the filter unit or water cooled by the cooling unit passes; a second water tube through which water heated by the heating unit passes; a water discharge unit that protrudes from a portion of the main body; and a water discharge cock (i) that downwardly protrudes from the water discharge unit, (ii) that is coupled to the first water tube and the second water tube, and (iii) that is configured to discharge water purified by the filter unit or water cooled by the cooling unit in a first stream and discharge water heated by the heating unit in a second stream, wherein the first stream is separated from the second stream is disclosed.

Examples disclosed herein relate to a dispensing device including a product unit with a pressure which transmits one or more products to an infuser, a water source with one or more CFValves that transmits water to the infuser, a gas source which transmits one or more gases to the infuser, and a dispensing area which dispenses a mixture generated via the infuser from a product unit input, a water source input, and a gas source input.

A drink dispensing device including one or more processors, a drink dispensing item located above a drink container positioning area, and a first sensor to determine when a drink container is located in the drink container positioning area, where the one or more processors initiate a drink container filling operation based on a first signal from the first sensor that the drink container is located in the drink container positioning area.
