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; a rod, inserted into the chamber via the through hole; and a rotatable element, covered on the rear portion. An outer surface of the rotatable element includes a first area and a second area, and the dual-mode fluid connector operates in a serve mode when the rotatable element is rotated to a status where the first area faces upward.

A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.

A system and method for dispensing beverage from a container, such as wine from a wine bottle. Dispensing may be automatically controlled based on a detected orientation of the container, e.g., dispensing may occur when a bottle is tilted as if to pour from the bottle and stopped when the bottle is oriented upright. Dispensing may be stopped when the container is rotated about its longitudinal axis even while in a pour orientation. A remaining amount of beverage in the container and/or an amount of pressurized gas used to drive dispensing may be detected and beverage dispensing controlled accordingly.

A water purifier according to an embodiment of the present invention may include a housing accommodating components for generating cold water and/or hot water; and a water chute which protrudes from a front surface of the housing, in which the water chute includes a water cock through which cold water or hot water flows; and a light emitting element which is mounted on the water cock to emit ultraviolet rays, in which the water cock includes a water inflow part which extends in a transverse direction and has a water inflow passage formed therein; and a water outflow part which extends in a direction intersecting the water inflow part at an end of the water inflow part and has a water outflow passage formed therein, in which the light emitting element is disposed on the upper side of the water outflow part, and in which the water outflow passage includes a sloping part having a shape in which a cross-sectional diameter thereof gradually decreases toward the lower end thereof.

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 system, method and device for monitoring fluid dispensing are described. The method includes coupling a plurality of sensors to a valve of a fluid dispensing assembly, wherein the valve is configured to operate in either a first state or a second state to control fluid flow from the inlet to the outlet. A change of a state of the valve is detected from the first state to the second state from the second state back to the first state. The detected data from the detected sequence of triggering events, a time duration and a predetermined flow rate may be transmitted through a wireless transceiver, to one or both of an external user device and a remote central monitoring unit for a determination of a volume V of fluid being dispensed.

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; a rod, inserted into the chamber via the through hole; and a rotatable element, covered on the rear portion and comprising a block portion, wherein the block portion is positioned in an interior of the rotatable element and arranged to operably engage with the outer flange.

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; 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 and including a sealing portion; wherein after the sealing portion detaches from the block element for a predetermined distance, an output terminal of the outlet check valve becomes a close status.
