As shown in fig. 14, the link (10) is a rod with holes at both ends, and is hinged with the 7-shaped rocker arm (6) and the valve core (11) through an upper link pin (601) and a lower link pin (1102), respectively.

The water discharge amount control device is composed of a water discharge amount control rod (9), a movable plate (14), a fixed plate (16), a shaft (15) and a C-shaped spring (18). As shown in fig. 19, the water discharge control lever (9) is a rod-shaped member having A, B both ends, a ball joint bar (901) at the B end (904), and a hole C (902) in the middle. The hole C (902) is connected with the water discharge control rod mounting hole (301) through a cylindrical pin, the ball head of the ball head rod (901) is arranged in an arc-shaped slideway (1601) of the fixed plate (16), the ball head rod (901) is matched with the arc-shaped slideway (1601) with small interference, the end A (903) is arranged below a return hook (1101) of the valve core (11), and the end B (904) is arranged below a water discharge compression bar (501) of the key (5). An included angle alpha, alpha is larger than 0 degree (as shown in figure 20) is formed between a motion track (20) of a ball head on the ball head rod (901) and a central line (19) of the arc-shaped slideway (1601), so that when the ball head rod (901) moves downwards, the fixed plate (16) is pulled to swing towards the direction of the valve core (11). As shown in fig. 16, the movable plate (14) is provided with a hole a (1401), wedge-shaped teeth (1402) and oblique slideways (1403); as shown in fig. 17, the fixed plate (16) is provided with an arc-shaped slideway (1601), a straight slideway (1602), a square hole (1603) and a hole B (1604); the movable plate (14), the fixed plate (16) and the C-shaped spring (18) (shown in figure 18) are arranged on the lug (1302) of the shell (13) by a shaft (15) (shown in figure 4), and the two ends of the C-shaped spring (18) press the movable plate (14) and the fixed plate (16) to be attached together.

The working process is as follows: a button on a toilet tank cover is pressed, the button on the toilet tank cover presses a button (5), a drain valve opening rod (502) on the button (5) presses a tail portion (703) of a Z-shaped hook (7), the hook (702) releases a float arm, a float (8) floats upwards under the buoyancy action of water, the float arm drives a 7-shaped rocker arm (6) to rotate through a power pin (603), the 7-shaped rocker arm (6) lifts a valve core (11) through a connecting rod (10), the valve core (11) is hung on wedge-shaped teeth (1402) of a movable plate (14) through a square pin (1103), the drain valve is opened, and water in the toilet tank flows into the toilet through a water inlet (1201) and a drain valve. Meanwhile, a water discharge compression bar (501) on the key (5) presses down an end B (904) of a water discharge control rod (9), the water discharge control rod (9) rotates around a hole C (902), a ball head of a ball head rod (901) slides in an arc-shaped slide way (1601) of a fixed plate (16), the fixed plate (16) drives a movable plate (14) to swing towards the direction of a valve core (11) together through a C-shaped spring (18), and the depth of combination of wedge-shaped teeth (1402) and square pins (1103) is increased. When a button on the cover of the toilet tank is released, the button (5) returns under the action of spring force, and the ball head of the ball head rod (901) is still in the arc-shaped slideway (1601) of the fixed plate (16) under the action of friction force. The floater (8) swings downwards around the floater shaft (2) along with the falling of the water level in the toilet water tank, the floater (8) drives the L-shaped rod (17) to move downwards, the round ball of the L-shaped rod (17) slides in the wedge-shaped slide way between the movable plate (14) and the fixed plate (16), the movable plate (14) swings towards the direction far away from the fixed plate (16), the depth of the combination of the wedge-shaped teeth (1402) and the square pins (1103) is gradually reduced until the wedge-shaped teeth are separated from the square pins, the valve core (11) falls and returns under the action of gravity and water pressure, and the drain valve is closed. A return hook (1101) of the valve core (11) presses down an A end (903) of the drainage control rod (9) to return the drainage control rod (9), and the fixed plate (16) also returns. As the water level in the toilet tank drops, the inlet valve of the toilet tank is opened, and as the water level in the toilet tank rises, the floater (8) floats and is hung by the hook (702) of the Z-shaped hook (7). When the water level rises to the set height, the water inlet valve is closed.

The deeper the key (5) is pressed in the working process, the greater the depth of the combination of the wedge-shaped teeth (1402) and the square pin (1103) is, and the more the water level is required to descend to separate the wedge-shaped teeth (1402) from the square pin (1103), so that the water discharge amount of the water tank can be controlled according to the pressing depth of the key. The push button (5) is particularly light, since the valve body (11) is lifted by the float (8).

The invention has the beneficial effects that: the water discharge amount of the water tank can be controlled according to the depth of the button pressing, and the button is particularly light.
