  • Patent number: 11148928
    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.

  • Publication number: 20210300791
    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.

  • Patent number: 7231935
    Abstract: This invention relates to a faucet, which comprises a body and a rotation control device. The body is assembled with a control valve and the control valve has a valve rod. The rotation control device comprises a shell, a handle and a fixing base. The shell is mainly forged with copper material and covers the body. The handle has a connecting part connected to the valve rod through the shell. Furthermore, the fixing base is made of plastic material and comprises a base disc and two fixing plates. The base disc is fixed within the shell and has a through-hole for the valve rod to pass through. The two fixing plates are formed on two opposite sides of the through-hole and tightly clipped with the connecting part of the handle.

  • Publication number: 20070039656
    Abstract: The present invention relates to a retainer band and a valve using the retainer band. The retainer band comprises an annular ring, a gasket and a block member. The annular ring has two terminals, which are opposite to each other. The gasket is formed on a periphery of the annular ring and is perpendicular to the annular ring. In addition, the valve comprises a body, an outlet pipe and an adaptor connected the body and the outlet pipe. The annular ring is provided to install around the adaptor and the block member is provided to wedge in between the two terminals of the annular ring. Therefore, when the outlet pipe is mounted on the second connecting portion of the adaptor, an entry of the outlet pipe tightly covers the annular ring and the block member, and is pressed against the gasket.
