  • Patent number: 8251090
    Abstract: A faucet includes a faucet body, a control knob, a follower and a switching valve. The faucet body has a water inlet, a water outlet and a switching port. The switching valve includes a driven rod moved with the control knob, a sealing plate having a plurality of connecting holes, a pressure release plate detachably pressing the sealing plate, and an elastic member mounted between the sealing plate and the pressure release plate. Thus, the switching valve can release the water pressure in the faucet body automatically so that the sealing plate is moved downward by its gravity to detach from the switching port, and the water inlet, the switching port and the water outlet are connected at a normal state to allow passage of water to prevent the water from being introduced into the shower head at the next usage.

  • Patent number: 7229194
    Abstract: This invention discloses a direct-type backlight unit structure, which at least comprises at least one light generation component and at least one reflection mirror. The light generation component is used to generate a light and the reflection mirror is set in a side of the light generation component, wherein the reflection mirror faces to the light generation component to form a paraboloid and the paraboloid extends till a top of the light generation component. The reflection mirror can also be set on the top of the light generation component, and faces to the light generation component to form two paraboloids from a center line of the top of the light generation component. The light generated from the light generation component, especially the upward light, can be reflected by the reflection mirror to turn toward the side direction, and finally intermix uniformly in a mixed space, and pass through a light emitting surface to form a uniform backlight.

  • Patent number: 7143777
    Abstract: A control valve includes a housing, two sealing gaskets, a shaft, a protective jacket, a fixed plate, a movable plate, a sleeve, a pressure balance unit, and an urging screwing member. Thus, the movable plate is rotated by operation of the shaft without producing deviation or loose displacement so as to balance the water pressure and control the water output and temperature exactly. In addition, the movable plate is driven by the shaft to rotate relative to the fixed plate without producing friction and wear between the movable plate and the fixed plate, thereby enhancing the lifetime of the control valve.
