     FIELD OF THE INVENTION 
       [0003]    The present invention relates to a toilet tank valve structure, and more particularly to a structure to control a knob and having a limiting device for partial discharge. 
       BACKGROUND OF THE INVENTION 
       [0004]    As shown in  FIG. 1 , a conventional dual flush toilet tank valve comprises a knob  10 , a rotatable shaft  20 , a pole  30 , first and second pull wires  40 , a whole discharge assembly  50 , a partial discharge assembly  60 , and a water seal  70 . When the knob  10  is turned clockwise or counter clockwise, the rotatable shaft  20  will link the pole  30  to turn clockwise or counter clockwise so as to pull the first or second pull wire  40  to lift the water seal  70  at different levels, releasing a whole discharge or a partial discharge. 
         [0005]    The prior art has the following disadvantages.
   1. The knob  10  is operated in two different directions to release a whole discharge or a partial discharge. A person may be easily confused as to which is the desired operational direction, and thus the undesired direction may be chosen in error.   2. It is necessary to provide enough space within the toilet tank for clockwise and counterclockwise rotation of the knob  10 . Therefore, the installation location for the conventional dual flush actuator is limited and cannot easily be retrofitted to existing toilet tanks.   3. The front of the toilet tank is provided with a toilet cover. Due to the toilet cover, the knob  10  is not suitable for installing at the front of the toilet tank. Usually, the knob  10  is installed at one side of the toilet. The knob  10  tends to hit the wall when the knob  10  is turned toward the wall, obstructing the actuation of the knob  10 .   4. When the knob  10  is installed at one side of the toilet tank, people are accustomed to turning the knob outward, not inward, and thus two-stage operation may, unintentionally, not be used.   5. Whole discharge or partial discharge depends on the whole discharge assembly  50  or the partial discharge assembly  60 . The knob  10  doesn&#39;t have a partial discharge limit mechanism itself, thus it is not easy for a user to identify the whole or partial discharge by manual operation of the knob.

When there is no water in the toilet tank, the partial discharge float  73  and the floating rod  72  are fallen down because of gravity to link the swing hook  71  to rotate around the pivot  71  in a tilted state. As shown in  FIG. 11 , when the toilet tank is filled with water, the partial discharge float  73  and the floating rod  72  are risen because of buoyancy to link the swing hook  71  to rotate around the pivot  712  in a level state. The whole discharge float  631  is deflected and rotated around the pivot  631  in a level state. 
         [0065]      FIGS. 5 and 12  show the whole discharge of the toilet tank valve structure. The whole discharge knob  12  links the first whole discharge pull wire  4 , the whole discharge side of the secondary actuator assembly, the second whole discharge pull wire and the inner tube  62  to move upward, and then the water seal  8  is lifted to open the outlet of the toilet tank and to drain the water in the tank. When the inner tube  62  is pulled to a highest position and the whole discharge knob  12  is released, the inner tube will slide downward until the limiting step  621  engages with the limiting step  632 . As the inner tube  62  stops sliding, the water seal  8  is located at a higher position and continues to drain water until the level of the water in the tank is at the position that the gravity of the whole discharge float  63  is larger than buoyancy. The whole discharge float  63  is deflected around the pivot  631  to lean the limiting step  632 . The limiting step  621  slides down from the limiting step  632 , and the inner tube  62  continues to slide down until the water seal  8  covers the outlet again to achieve the whole discharge. 
         [0066]      FIGS. 9 and 13  show the partial discharge of the toilet tank valve structure. The partial discharge knob  11  links the first partial discharge pull wire  5 , the partial discharge side of the secondary actuator assembly, the second partial discharge pull wire and the brake rod  91  to move upward. The brake rod  91  is rotated around the pivot  624 . The inner tube  62  is lifted up through the brake rod  91  to link the water seal  8  to open the outlet of the toilet tank and to drain the water in the tank. The limiting hook  92  is rotated around the pivot  922 , and the lower end of the limiting hook  92  is deflected to engage with the protruding step  611  in the body  61 , which confines the limiting hook  92  to move upward continuously. The partial discharge knob  11  is confined to continuous rotation by means of the limiting device  9 . When the partial discharge knob  11  is released, the inner tube  62  will slide down until the limiting step  623  engages with the limiting step  711 . As the inner tube  62  stops continuing sliding down, the water seal  8  is located at a lower position and continues to drain water until the level of the water in the tank is at the position that the gravity of the partial discharge float  73  and the floating rod  72  is larger than buoyancy. The partial discharge float  73  and the floating rod  72  slide down because of gravity. The swing hook  71  is deflected and rotated around the pivot  631  to lean the limiting step  711 . The limiting step  623  slides down from the limiting step  711 , and the inner tube  62  continues to slide down until the water seal  8  covers the outlet again to achieve the partial discharge. 
         [0067]    Accordingly, by the limiting device  9 , the user is able to exactly operate the knob unit  1  for a whole discharge or a partial discharge. 
         [0068]      FIGS. 14A through 14F  show the details of the secondary actuator assembly. The secondary actuator assembly translates the input mechanical movement of each of the first partial discharge pull wire and the first whole discharge pull wire into an increased output movement for each corresponding output second discharge pull wire from the secondary actuator assembly. The secondary actuator assembly permits the primary actuator assembly to operate with reduced size, thereby enabling installation of the primary actuator assembly in a space substantially the same as the prior art actuator assemblies which the toilet tank valve structure is intended to replace. 
         [0069]      FIG. 14A  shows the secondary actuator assembly  1400 . Pull wires from the primary actuator assembly are coupled to the secondary actuator assembly input connection  1410 . The output pull wires from the secondary actuator assembly are coupled to the flush valve by the secondary actuator assembly output connection  1420 .  FIG. 14C  shows the secondary actuator mounting plate  1440 .  FIG. 14E  shows the secondary actuator partial discharge actuator arm  1460  which is rotatably coupled to the pivot point  1443  on one side of the secondary actuator mounting plate  1440  through the partial discharge actuator arm pivot receptacle  1463 . The first partial discharge pull wire  15  from the primary actuator box couples, via the secondary actuator housing input connection  1410  and the secondary actuator input channel  1445 , to the partial discharge actuator arm input connection  1461  on partial discharge actuator arm  1460 . The partial discharge actuator arm output connection  1462  couples the second partial discharge output pull wire  5 , via the secondary actuator output channel  1446  and secondary actuator output connection  1420 , to the flush valve. When the secondary actuator top cover  1430  is installed, it retains the secondary actuator partial discharge actuator arm  1460  in place and rotatably coupled to the secondary actuator mounting plate  1440 . 
         [0070]      FIG. 14F  shows the secondary actuator whole discharge actuator arm  1470  which is rotatably coupled to the pivot point  1444  on one side of the secondary actuator mounting plate  1440  through the whole discharge actuator arm pivot receptacle  1473 . The first whole discharge input pull wire  14  from the primary actuator box couples, via the secondary actuator housing input connection  1440  and the secondary actuator input channel  1445 , to the whole discharge actuator arm input connection  1471  on whole discharge actuator arm  1470 . The whole discharge arm output connection  1472  couples the second whole discharge output pull wire  4 , via the secondary actuator output channel  1446  and secondary actuator output connection  1420  to the flush valve. When the secondary actuator bottom cover  1450  is installed, it retains the secondary actuator whole discharge actuator arm  1470  in place and rotatably coupled to whole discharge pivot point  1441  on the secondary actuator mounting plate  1440 . 
         [0071]      FIG. 15  shows an assembled toilet tank valve structure with primary and secondary actuators in accordance with the toilet tank valve structure. 
         [0072]      FIGS. 16A through 16F  show various locations where the flush handle mounting opening may be placed on the toilet tank. These few examples are illustrative of the type of flush handle mounting locations which may commonly be found on existing toilet tanks, as well as those in new manufactures. For convenient access, the flush handle pair is generally mounted substantially horizontally and with the handle pair facing toward the front of the toilet tank. As shown in  FIG. 16G , the handle pair orientation may alternatively be vertical or any other orientation between. 
         [0073]      FIG. 17  shows a flow chart illustrating a waste treatment method in accordance with some embodiments. 
         [0074]    The method begins from the Step  1702 . At the Step  1704 , a user&#39;s flush motion is received. If the user is performing a full flush, the method goes to the Step  1706 . At the Step  1706 , the full flush bar is turned by a user. At the Step  1708 , the user&#39;s turning motion is transformed into a linear horizontal pulling motion at the first actuator by a rotational member. At the Step  1710 , the horizontal pulling motion is amplified to a larger vertical pulling motion by a rotational lever at the secondary actuator device. At the Step  1712 , a full flushing member is triggered to remove a solid waste. The method of performing a full flush is ended at the Step  1714 . If the user is performing a partial flush, the method goes to the Step  1716  after the Step  1704 . At the Step  1716 , the partial flush bar is turned by a user. At the Step  1718 , the user&#39;s turning motion is transformed into a linear horizontal pulling motion at the first actuator by a rotational member. At the Step  1720 , the horizontal pulling motion is amplified to a larger vertical pulling motion by a rotational lever at the secondary actuator device. At the Step  1722 , a partial flushing member is triggered to remove a liquid waste. The method of performing a partial flush is ended at the Step  1724 . 
         [0075]    In some embodiments, the longest side of the secondary actuator partial discharge actuator arm  1460  and whole discharge actuator arm  1470  are able to be 2¾ inch long. In alternative embodiments, the longest side of the secondary actuator partial discharge actuator arm  1460  and whole discharge actuator arm  1470  are able to be between  1 . 0  inch to 5.0 inch long. In some embodiments, the primary actuator assembly is able to be enclosed in a case having a size in 1.75 inch long×1.63 inch wide. Any sizes of the case are also applicable as long as the case is able to be fitted into the water tank. Further, the discharge handle or the user input device is able to be fitted in the center of the primary actuator assembly case. Moreover, the connection wire between the primary and the second actuator assembly is able to be located 0.38 inch from the center of the discharge handle. 
         [0076]    Some embodiments of the present application provide means for enlarging or leveraging user&#39;s input on the primary actuator assembly, such as turning the flush handle, through the functions and the mechanical components of the secondary actuator assembly. For example, in some embodiments, user&#39;s motion for flushing a toilet that is performed on the rotational diameter of the 0.88 inch actuating arm in the primary actuator assembly is able to be amplified or enlarged by the secondary actuator arm, lever arm,  1460  and  1470  having a length 2¾ inch. 
         [0077]    In some embodiments, whole discharge and partial discharge components may be distinguished with colors to facilitate manufacturing, assembly and installation, and for user convenience. For example, a green insert may be provided for the whole discharge flush handle and a red insert provided for the partial discharge flush handle to facilitate user identification of the functionality of the handles. The color inserts for the flush handle identification may additionally be interchangeable. In addition, primary and secondary actuator components may be similarly colored to facilitate manufacturing and assembly. For example, components related to the whole discharge side of the primary actuator, secondary actuator and their interconnecting components may be colored green, whereas the partial discharge counterparts may be colored red. Although the colors for various components have been described with respect to several specific embodiments, it will be understood by those skilled in the art that any number of colors, combinations of colors or patterns, or other ways of identifying the whole discharge components from the partial discharge components is within the scope and spirit of the invention. 
         [0078]    Although the toilet tank valve structure has been shown and described with respect to several embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
