  • Publication number: 20110266355
    Abstract: A water mixer of the present invention is adapted to be installed in a faucet. The water mixer has a balance unit and a mixing element, and the water mixer can be connected to two water sources. When the pressure of one water source varies rapidly, the balance element can modulate the effect that may influence the flow rate of each water source. The mixing element is, on the other hand, adapted to mix the two water flows. As such, the faucet provided with the water mixer of the present invention can stabilize the temperature of the mixed water outlet.

  • Patent number: 7409968
    Abstract: A faucet with a water outlet controlled by a central pull stick capable of being installed easily comprises a valve body consisting of a main body and a head portion connected together by screw threads. The valve body further comprises a main body and a head portion connected to the main body by a screwing mechanism. A stopper on the main body and a retaining part on the head portion are coupled together upon the screwing so that the retaining part will be fixed on an attached object after the valve body penetrated through the object. Thereby, idle rotation between the head portion and the main body can be prevented. Further, the valve body can be locked onto the attached object by screws applied through the upper surface of the object, facilitating quick installation of the valve body.
