  • Water Faucet
    Patent number: 5146951
    Abstract: The present invention relates to an improvement structure of a faucet water inlet, and more particularly to an improvement structure of a faucet water inlet characterized in that the main body of the faucet, the internal component and the water outlet are individually die cast, and at both of the side edges of the internal component and at the position corresponding to the water inlet of the main body, a cold water inlet chamber and a hot water inlet chamber in the form of a vertical differential semicircular cross section are with this construction, it is not only easy to manufacture, but also the product defective rate is reduced. In addition, the main body and the water outlet can be arranged optionally, so that in case of a failure, it does not require to replace all of the components and provide for easy maintenance.

  • Device of water plug noise elimination and water seal flush toilet
    Patent number: 5119845
    Abstract: This invention relates to an improvement of a float valve device, and more particularly to a float valve device including a water plug noise elimination and water seal assembly for flush toilets, with its major features of adding a noise eliminating water inlet unit at the water outlet structure of such a flush toilet, by using the bores surrounding the water inlet unit to produce the compliant flow during water intake by applying the flux dynamics principle to kill the noise, and by adding a triangle spring within the water outlet seat below a float crank rod to function as the indirect pivot of a float lever to achieve a load-saving purpose and to increase the water seal rate, and since the pivot is at lower position, the float is able to precisely open and close the water inlet to avoid the tear and wear of the water seal washer so as to prolong the service life of the water seal device while achieving the purpose of saving the water supply.
