Principle of operation
1. Opening process of drain valve
When the button 7 is pressed by a hand, the button 7 moves downwards, the control end pressing point 702 on the button 7 pushes the control end of the rocker arm 14 to swing downwards, and the limiting rod pressing point 701 pushes the limiting rod 26 to slide downwards. When the control end of the rocker arm 14 swings to the horizontal position, the rocker arm continues to swing downwards to the lowest point under the action of the spring B16, and is positioned at the water discharging position of the water bag 13. When the key 7 reaches a certain depth, the key 7 is released, and the key 7 returns under the action of the return spring. The stopper rod 26 is locked by the lock rod 25.
At this time, the control valve 15 makes the water discharge pipe 1502 communicate with the water inlet and discharge pipe 1503, and the water in the water bag 13 is discharged to the toilet bowl by the pressure of the water in the toilet tank, and the water bag 13 is crushed. The water bag 13 pulls the sliding valve rod 31 through the pull wire 12, the driving lever 11 and the pull rope 22, and the upper valve rod 32 is clamped by the lower claw 18 and cannot move upwards. The sliding valve rod 31 continuously slides upwards to contact with the inclined surface of the upper claw 21 against the pulling force of the spring C30, the upper claw 21 is pushed to swing outwards, the upper claw 21 drives the lower claw 18 to swing outwards through the connecting rod 19, and the upper valve rod 32 is released. The upper valve rod 32 drives the lower valve rod 33 and the valve plate 36 to rapidly move upwards under the action of the spring C30, the drain valve is opened, and water in the toilet water tank enters the toilet through the water inlet hole 202 and the water outlet hole 203 on the valve seat 2. The sliding valve rod 31 continues to move to reach the upper part of the upper machine claw 21 and is hung by the upper machine claw 21.
During the squashing of the water bladder 13, the valve-closing protrusion 1101 of the actuating lever 11 moves upward to be in contact with the valve-closing arm 20. The valve closing arm 20 swings upward, the valve closing protrusion 1101 comes above the valve closing arm 20, and then the valve closing arm 20 returns by gravity.
2. Closing process of water discharge valve
The lower valve rod 33 moves upwards to swing the release lever 23 and the return lever 17. The swinging of the release lever 23 causes the swinging finger 2301 to touch the locking rod 25 and swing upward, sliding down under the locking rod 25 and then straightening. The return lever 17 swings to press the spring end of the rocker arm 14, and jumps to the water inlet position of the water bag 13 under the action of the spring B16, and the control end of the rocker arm 14 is in contact with the limit protrusion 2601 of the limit rod 26, so that the opening degree of the control valve 15 when the water bag 13 enters water is determined by the height of the position of the limit rod 26, and the higher the position is, the larger the opening degree is. At this time, the pressure inside and outside the water bag 13 is equal, and under the action of the elastic force of the water bag and the pulling force of the spring a6, the water in the toilet tank enters the water bag 13 through the water inlet pipe 1501, the control valve 15 and the water inlet and outlet pipe 1503, the water bag 13 gradually returns, and the valve closing protrusion 1101 of the driving lever 11 moves downwards to contact with the valve closing arm 20. The valve-closing arm 20 swings downward by being pushed by the valve-closing projection 1101, thereby bringing the upper pawl 21 to swing. The upper claw 21 releases the sliding valve rod 31, and the valve core falls under the action of gravity and water pressure to close the drain valve.
The downward movement of the valve core drives the return lever 17 and the release lever 23 to swing, the swing finger 2301 of the release lever 23 pushes the counterweight end of the locking rod 25 to swing upwards, the locking end 2501 is separated from the limiting rod 26, and the limiting rod 26 returns under the action of the return spring.
As can be seen from the whole working process, the depth of the press of the button 7 controls the position of the limiting rod 26, thereby controlling the opening of the control valve 15, thereby controlling the rebound speed of the water bag 13, determining the time of the downward movement of the valve closing protrusion 1101, contacting with the valve closing arm 20 to release the valve core, namely the time of the water drainage process, and controlling the water drainage quantity.
