In the drawings, the utility model and water intaking valve are supporting, install in the water tank of present lavatory.It comprises that both sides have the cylinder 9 of gathering sill, be connected the push-button socket 21 on the cylinder 9, the button spring 3 that makes the draining push-button reset is arranged in the push-button socket 21, snapping in push-button socket 21 also does within it, the mobile down draining button that is used to control the stepping draining, this draining button is divided into half row's button 2 and full row's button 1, by pushing the draining button, the bottom of partly arranging button 2 and full row's button 1 contacts with the top of partly arranging lever 4 and arranging lever 5 entirely respectively, half row that the other end of partly arranging lever 4 and full row's lever 5 all has a protruding position with the bottom respectively by connecting rod 6 crossbeam of helping pull a cart on 8 on the end and riser 7 is hinged, half row, 8 belows that just are enclosed within the outer and crossbeam of riser 7 of helping pull a cart, and on the outer wall work of riser 7, following motion, in the lower end of riser 7 draining O-ring seal 13 is installed, draining O-ring seal 13 is fixed by pad 12 and card 14.When riser 7 moved both vertically in Connection Block 10, drive draining O-ring seal 13 was mentioned or is put down, thereby finished the process of draining or water shutoff.And control half draining, full draining partly arrange float 19, full row's float 17 just is connected on half tooth-arranging strip 18 and the full tooth-arranging strip 15 by latch, and it all designs in same cylinder 9, all there is a convex tendon at the middle part of partly arranging float 19 and full row's float 17 and protrudes from outside the gathering sill of cylinder 9, and can do along half tooth-arranging strip 18 and full tooth-arranging strip 15, the following adjustment, half tooth-arranging strip 18 and full tooth-arranging strip 15 are articulated in half a row's kelly 20 and a complete end of arranging kelly 16 respectively, the other end of partly arranging kelly 20 and full row's kelly 16 all is articulated on the Connection Block 10, and Connection Block 10 joins with screw-in mode and base 11 and rotates in certain angular range.

Operating principle of the present utility model is:

When being in full water state in the water tank of the present lavatory of the utility model, partly arrange float 19 and full row's float 17 is moved upward by the buoyancy of water effect, drive and partly arrange kelly 20 and full row's kelly 16 turns on the maximum spacing position.At this moment, the utility model also promptly is in the water shutoff state.

When pushing full row's button 1, Jie Chu full row's lever 5 rotates because of being subjected to arrange pushing of button 1 entirely with it, driving riser 7 by connecting rod 6 moves upward, when riser 7 moves to certain altitude, full row's kelly 16 blocks the protruding position of riser 7 bottoms, because full row's float 17 is subjected to the buoyancy of water effect, and riser 7 can not down be resetted.At this moment, the utility model is in full hull-borne.When drawdown arrives certain position, the buoyancy of full row's float 17 is not enough to support to conduct oneself with dignity and during the weight of riser 7, full row's float 17 moves downward, full row's kelly 16 natures are thrown off the protruding position of riser 7 bottoms with regard to outside motion, riser 7 resets downwards with that, thereby riser 7 drives the delivery port sealing of draining O-ring seals 13 with base 11, and at this moment the utility model then is in the water shutoff state.

When pushing half row's button 2, the lever 4 of partly arranging of contact rotates because of being subjected to half pushing of button 2 of row with it, driving half row by connecting rod 6 helps pull a cart and 8 moves upward, because of half row, 8 belows that are enclosed within the outer and crossbeam of riser 7 of helping pull a cart, riser 7 is also corresponding to be raised, and when half row helps pull a cart 8 when moving to certain altitude, partly arranges kelly 20 and blocks the help pull a cart protruding position of 8 bottoms of half row, owing to partly arrange float 19 and be subjected to the buoyancy of water effect, make half row help pull a cart 8 and riser 7 can not down reset.At this moment, the utility model is in half hull-borne.Because partly arrange pushing of button 2, its stroke is less than the stroke of pressing full row's button 1, so the distance that riser 7 moves upward is short, arranges the protruding position that kelly 16 can't block riser 7 bottoms entirely, so full hull-borne can not occur.When drawdown arrives certain position, during 8 weight that the buoyancy of partly arranging float 19 is not enough to support to conduct oneself with dignity and half row helps pull a cart, partly arranging float 19 moves downward, partly arrange kelly 20 nature and throw off the help pull a cart protruding position of 8 bottoms of half row with regard to outside motion, half row helps pull a cart and 8 resets downwards with that, riser 7 also moves downward immediately, thereby riser 7 drives the delivery port sealing of draining O-ring seals 13 with base 11, and at this moment the utility model is in the water shutoff state equally.
