Abstract

A flush tank includes a water entrance to receive water from a water reservoir, a water outlet for discharging the water and controlled by a valve member, and a water inlet disposed in the upper portion to receive waste water from waste water suppliers. A valve device is attached to the lower portion of the tank member, to control and to allow little water to flow into the tank member via the water entrance. Another valve device is attached to the upper portion of the tank member, to control and to allow the waste water to flow into and to fill the tank member via the water inlet.

A flush tank comprising:

a tank body including a water entrance for coupling to a water reservoir and to receive water from the water reservoir, said tank body including a lower portion having a water outlet provided therein, and including an upper portion having a water inlet for receiving waste water,
a first valve device attached to said lower portion of said tank body, to control said water entrance, and to allow little water to flow into said tank body via said water entrance,
a valve member rotatably secured to said tank body with a pivot pin, to allow said valve member to be rotated relative to said tank body and to either open or enclose said water outlet of said tank body,
a second valve device attached to said upper portion of said tank body, to control said water inlet, and to allow the waste water to flow into and to fill said tank body via said water inlet, and
a control device disposed in said tank body to open and close said water outlet of said tank body, and to control water flowing out through said water outlet of said tank body, said control device including an arm pivotally secured to said tank body, a cable coupled between said arm and said valve member, to allow said arm to open said valve member via said cable, and a knob coupled to said arm to actuate said arm to open said valve member,
said control device further including a lever pivotally secured in said tank body, said lever including a first end having a retainer provided thereon to engage with said valve member, and to retain said valve member at an open position, and said lever including a second end having a float provided thereon to selectively disengage said retainer from said valve member, and
said control device further including a bar having a first end pivotally secured in said tank body, said bar including a second end having a weight provided thereon to engage with said float, and to depress said float, and to disengage said retainer from said valve member.
