  • Patent number: 8268168
    Abstract: A filter unit for a shower system includes a filtering housing and a filter core. The filtering housing includes a main body having a water inlet and a plurality of water outlets, wherein the water inlet is arranged to connect with the water supply tube so as to allow water to flow into the filtering housing through the water inlet, wherein one of the water outlets is connected with the second end of an extension tube of a shower head. The filter core is received in the filtering housing, and is capable of filtering unwanted substances in the water flowing from the water supply tube, wherein the filtered water is guided to flow out of the filtering housing through one of the corresponding water outlet to the extension tube and the shower head.

  • Publication number: 20110147477
    Abstract: A fluid diversifying apparatus includes a fluid passage member having a fluid passage therewithin, and a fluid diversifying unit communicatively connected to the fluid passage for dispensing fluid with predetermined spray pattern. The fluid diversifying unit has a plurality of fluid selection inlets and a plurality of fluid dispensing portions communicatively connected to each of respective the fluid selection inlets for dispensing a spray pattern of the fluid through each of the dispensing portions, such that when one of the fluid selection inlet is selectively aligning with the fluid passage outlet, the fluid flow is guided to enter selected the fluid selection inlet to dispense fluid from respective the fluid dispensing portion, so as to selectively control the spray pattern from one of the fluid dispensing portions.

  • Publication number: 20100320295
    Abstract: A shower head apparatus includes a shower head and an adjustable flow rate arrangement. The shower head has a head portion, handle portion, and a water passage extended from the handle portion to the head portion for allowing water flowing from the handle portion to the head portion. The shower head further has a front opening slot to communicate with the water passage. The adjustable flow rate arrangement includes a water valve coaxially supported within the water passage, wherein the water valve has a size adjustable water passageway communicating with the water passage for controllably adjusting a flow rate of the water passing through the water passage in responsive to size-change of the water passageway. A thumb actuator extended out of the handle portion of the shower head through the opening slot is provided to selectively adjust the size of the water passageway to control the flow rate of water.

  • Publication number: 20090194613
    Abstract: A shower head apparatus includes a shower head and an adjustable water flow rate control for adjustably control the rate of the water flow through the passage of the shower head. The adjustable water flow rate control includes a control knob and a control valve which is rotatably supported within the shower head and is driven to be rotated via the control knob, wherein the control valve has a water through channel aligning with the passage, in such a manner that when the control knob is selectively rotated at its rotational angle to drive the control valve to rotate, the water through channel of the control valve is adjustably offset with the passage for controlling the water flow rate through the shower head. Therefore, the present invention is adapted to provide better shower experience and to provide a water saver feature for the shower head.

  • Publication number: 20080250556
    Abstract: A showerhead assembly includes a water adapter and a water flow diverter. The water adapter includes two rotatable frames having a first water outlet and a second water inlet respectively and a supporting frame, having a first water inlet communicating with the first water outlet and a second water outlet, rotatably coupled between the rotatable frames. The water flow diverter contains a first water opening communicating with the first water outlet, a second water opening communicating with the second water inlet, and a water exit. The water flow diverter is adapted for selectively controlling the water flow at one of the conditions including the water flowing out at the second water outlet only, the water flowing out at the water exit only, and the water flowing out at both the second water outlet and the water exit at the same time.
