Abstract: The present invention discloses a hot water dispenser comprising a water tank, an expansion chamber, and a Venturi module. The expansion chamber comprises a top shell, a bottom shell connected to the top shell, and a flexible bladder. Wherein, the water tank is connected to a dedicated faucet, the Venturi module is connected to a water source through the faucet, so when the dedicated faucet is closed, the expansion chamber then immediately creates suction and removes a part of the hot water from the water tank and into the expansion chamber to avoid hot water residue dripping from the faucet. In addition, when the water in the water tank is heated to its boiling point, a part of the hot water will be sucked into the expansion chamber to reduce the pressure in the water tank and prevent the hot water from being ejected out of the faucet due to vapour.

Abstract: An ultraviolet light-emitting faucet includes an inlet assembly, an outlet assembly, an operation assembly, a water-proof light-emitting module and a light guide. The operation assembly includes a conduit for connecting an inlet channel of the inlet assembly to an outlet channel of the outlet assembly. The conduit includes a cave, an optical channel, and an operation chamber including a first open end in communication with the cave and a second open end in communication with the optical channel. The water-proof light-emitting module is located in the cave and operable to cast ultraviolet light and visible light into the operation chamber through the first open end of the operation chamber. The visible light further goes into the optical channel through the second open end of the operation chamber. The light guide is supported on the operation assembly and operable to guide the visible light out of the optical channel.
