  • Patent number: 8308085
    Abstract: The present invention provides a showerhead that allows a bather to switch among at least three different water delivery functions. In the first function, the showerhead delivers a concentrated fluttering spray at a rate not to exceed 1.5 GPM (5.75 GPM). In the second function, the showerhead delivers a combined spray pattern, wherein the fluttering spray and a radially dispersed precision spray are simultaneously delivered to the bather at a rate not to exceed 2.0 GPM (7.57 L/min) for the combined water flow. In the third function, the showerhead delivers the precision spray pattern at a rate not to exceed 2.0 L/min (7.57 GPM). The combination spray pattern is effected without compromising either the desirable massaging and cleaning effect of water delivery or the inherent water conservation benefits.

  • Patent number: 7896259
    Abstract: The present invention provides a water saving showerhead that allows a bather to switch among at least three different water delivery functions. In the first function, the showerhead delivers a concentrated fluttering spray. In the second function, the showerhead delivers a combined spray pattern, wherein the fluttering spray and a radially dispersed precision spray are simultaneously delivered to the bather. In the third function, the showerhead delivers the precision spray pattern. The combination spray pattern is effected without compromising either the desirable massaging and cleaning effect of water delivery or the inherent water conservation benefits. In addition, the showerhead of the present invention provides an automatic return feature for return of the showerhead to the first function when water pressure to the showerhead falls below a predetermined bottom threshold.

  • Patent number: 7066407
    Abstract: A shower head assembly includes an outer housing, an inner housing, a catch cap, and an impeller. Thus, the catch cap catches the water flow and introduces the water flow through the water inlet hole into the air chamber so as to reduce the water flow rate, thereby achieving the purpose of saving water. In addition, the water flow is ejected outward in a radiating manner by rotation of the impeller, thereby providing a massaging effect to the user.

  • Patent number: 6942190
    Abstract: A sucker assembly includes a sucker, a clamping unit, a housing, and an adjusting rotation cover. Thus, the sucker assembly that can be fixed on the wall rapidly and conveniently, thereby facilitating the user operating the sucker assembly. In addition, the sucker assembly can be used to suspend a hanging rod which has two ends each pressed by the press member of the clamping unit, so that the hanging rod is positioned by the sucker assembly, thereby preventing the hanging rod from detaching from the sucker assembly during the working process.

  • Patent number: 6896228
    Abstract: A fixing device for a bath support rack includes a base, a body mounted on the base, a clamping rod mounted on the body, and a press mechanism movably mounted on the body and having a distal end rested on a central portion of the base, so that the press mechanism can be pressed downward to compress the base. Thus, the fixing device can be positioned on an object, such as a flat wall, rigidly and stably. In addition, the fixing device can be detached from the object easily and conveniently.
