A self-service wine tasting system includes automatic wine dispensers, a cloud server and user terminals. The automatic wine dispenser includes wine dispensing stations, a machine identity and a first telecommunication module. The first telecommunication module is connected to a control chip of the automatic wine dispenser. The cloud server includes a storage and a second telecommunication module. The second telecommunication module is in communication connection with the first telecommunication module. The storage stores wine storage information associated with the machine code of each automatic wine dispenser. The user terminal includes an identification device and a third telecommunication module. The third telecommunication module is in communication connection with the second telecommunication module. The self-service wine tasting system facilitates the wine taster to record the tasting behavior.

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.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a hollow element including an inner surface and an outer surface which allows for a passage of one or more of one or more fluid elements and one or more gaseous elements, a constraining element with one or more openings and one or more non-open elements, one or more blocking elements configured to stop the passage of the at least one of the one or more fluid elements and the one or more gaseous elements when the one or more blocking elements are in a first position relative to the one or more openings, and a movement device configured to move the one or more blocking elements to a second position relative to the one or more openings which allows for the passage of the one or more fluid elements and the one gaseous elements through the one or more openings in the constraining element.

A beverage supplier includes: an inlet conduit communicated with a beverage container; a pumping and cooling device communicated with the inlet conduit, pumping and cooling a beverage from the beverage container, and outputting a cooled beverage; and an output unit, which is electrically connected to the pumping and cooling device and controls output of the cooled beverage. In a first state, the pumping and cooling device pumps and cools the beverage from the beverage container through the inlet conduit. In a second state, the pumping and cooling device empties the cooled beverage remained in the pumping and cooling device.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a hollow element including an inner surface and an outer surface which allows for a passage of one or more of one or more fluid elements and one or more gaseous elements, a constraining element with one or more openings and one or more non-open elements, one or more blocking elements configured to stop the passage of the at least one of the one or more fluid elements and the one or more gaseous elements when the one or more blocking elements are in a first position relative to the one or more openings, and a movement device configured to move the one or more blocking elements to a second position relative to the one or more openings which allows for the passage of the one or more fluid elements and the one gaseous elements through the one or more openings in the constraining element.

A dispenser includes a body having a an exterior surface, an interior surface, a first chamber, a first opening in fluid communication with the first chamber and extending through the body, a second opening in fluid communication with the first chamber and extending through the body, a first valve and a second valve disposed on the body, the valves having a closed and an open configuration, and an actuator disposed at least partially within the first chamber. The actuator may be configured to increase and decrease pressure in the first chamber such that the first valve and the second valve change from their respective closed configurations to their respective open configurations and from their respective open configurations to their respective closed configurations. When in the closed configuration, flow through the valves is impeded.

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.

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 dual-mode fluid connector includes: a hollow connecting element, comprising a chamber inside the hollow connecting element; a material tube, positioned on the hollow connecting element and connected through the chamber; a cleaning tube, positioned on the hollow connecting element and connected through the chamber; a head portion, positioned on one terminal of the hollow connecting element and having a connecting opening, wherein the connecting opening can be detachably connected to a material container; a rear portion, positioned on another terminal of the hollow connecting element and having a through hole; and a rod, inserted into the chamber via the through hole; a bended plate, sleeved on the rear portion; and a rotatable element, covered on the rear portion and the bended plate, and engaged with the rod.

A dual-mode fluid connector includes: a hollow connecting element, comprising a chamber inside the hollow connecting element, wherein a protuberant block element is arranged on an inner surface of the chamber, and the block element divides an interior space of the chamber into a first space and a second space; a material tube, positioned on the hollow connecting element and connected through the chamber; a cleaning tube, positioned on the hollow connecting element and connected through the chamber; a head portion, positioned on one terminal of the hollow connecting element and having a connecting opening, wherein the connecting opening can be detachably connected to a material container; a rear portion, positioned on another terminal of the hollow connecting element and having a through hole; and a rod, inserted into the chamber via the through hole.
