Mechanism, the linkage mechanism include two-stage rocking bar, respectively level-one rocking bar 4 and second level rocking bar 5, the level-one rocking bar 4 and second level rocking bar 5
It is rotationally connected with respectively into water valve body 1 and is in be arranged side by side, the setting of second level rocking bar 5 is in 4 inside of level-one rocking bar and intakes
Between valve body 1；The side of the level-one rocking bar 4 is extended one and argues for the sake of arguing 41, this is argued for the sake of arguing 41 is connected with level-one rocking bar side
And with one substantially 110 ° of angle；The arguing for the sake of arguing to rotate of the floating drum 3 and 1 side of level-one rocking bar connect, and is formed for driving
The kinetoplast of linkage mechanism movement；The gasket 2 is mounted on second level rocking bar 5, and when floating drum 3 is moved up and down with linkage
Mechanism kinematic and turn off or on the back pressure valve 11 into water valve body.
As a preference, the back pressure valve 11 of the water inlet valve body is set to the top-side of the water inlet valve body 1,
The level-one rocking bar 4 and second level rocking bar 5 are side by side and the side that is rotationally connected with where the back pressure valve 11 of the water inlet valve body 1
Face, arguing for the sake of arguing for level-one rocking bar side 41 rotate with the floating drum 3 and connect in the side of the water inlet valve body.
As a preference, the top-side position of the water inlet valve body 1 is equipped with two pairs of axis holes 12,13；The level-one
The medial surface of rocking bar 4 is equipped with two parallel lugs 42, and the opposite exterior lateral sides of two lug are respectively equipped with shaft A43, shaft A43 with
The one pair of them axis hole 12 of water inlet valve body socket-connects cooperation, the rotating fulcrum of formation level-one rocking bar；The one of the second level rocking bar 5
Two outside of end is equipped with shaft B51, and another pair axis hole 13 of shaft B51 and water inlet valve body 1 socket-connects cooperation, and formation second level is shaken
The rotating fulcrum of bar；4 side of level-one rocking bar argue for the sake of arguing 41 end at be equipped with connecting hole 44, with the company being set on floating drum 3
Spindle 31 rotates connection.
As a preference, a raised line 45 is arranged in the upper end medial surface of the level-one rocking bar 4, on the second level rocking bar 5
End is bar shaped upper arm 52, and when floating drum decline, the raised line 45 of level-one rocking bar is pressed on the upper arm 52 of second level rocking bar, to open
The back pressure valve 11 of water inlet valve body, makes inlet valve be in water inlet state；Two lugs 42 of the level-one rocking bar 4 prolong separately down
An arm of force 46 is stretched, the other end two sides of the second level rocking bar are equipped with protruding shaft, when floating drum 3 rises, two arm of forces 46 of level-one rocking bar
It is just pressed in the protruding shaft 53 of second level rocking bar two sides, to close the back pressure valve 11 of water inlet valve body, is in inlet valve only
Water state.
The linkage structure suitable for inlet valve floating drum and back pressure valve of the utility model, total lever ratio=L4/L3 ×
L2/L1, wherein L4, L3 are respectively the power arm and resistance arm of level-one rocking bar 4, and L4 > L3, L2, L1 are respectively second level rocking bar 5
Power arm and resistance arm, and L2 > L1, in the present embodiment, total lever ratio=L4/L3 × L2/L1=(26/7) X (24/8.5)=
3.7X2.8=10.4, when the power arm L4 of level-one rocking bar 4 is 26mm, total lever ratio can reach 10.4, in this way, the length argued for the sake of arguing
It greatly shortens, the volume of inlet valve also greatly reduces；The inlet valve for such as using prior art level-one rocking bar, will reach same thick stick
