Description

Flushing device for toilet cistern

The utility model relates to a kind of flushometer of water-closet tank, more specifically says so to the improvement of the flushometer of sitting type toilet seat.

The present water-closet tank flushometer that uses, bath all has only a kind of selection mode, and it all is certain separating discharging quantity of water regardless of different kinds of promptly, is unfavorable for very much using water wisely.

The purpose of this utility model is exactly that a kind of water-closet tank flushometer with two kinds of water yields bath modes will be provided, make its water saving, simple in structure, volume is little.

The purpose of this utility model is achieved in that it is to have increased by a push switch on the flushometer of original water-closet tank, affect the clutch Button Block and swim the seat action by the clutch backguy, air vent on the clutch for clutch control seat is opened, make the following air chamber of plug that blocks water be full of water by ventilating pipe, order blocks water to fill in and closes the purpose that reaches water-saving.

Distinguishing feature of the present utility model is exactly the selection that is to have two kinds of water yields, makes the user on demand and selector switch; Simple in structure, volume is little, be convenient to transportation and store; The member cost is lower.

Below in conjunction with accompanying drawing the utility model is described in further detail:

The flushometer of this water-closet tank is with push switch 1, is installed on the thread seat 2, drives the plug 6 that blocks water by connecting rod 4 and interlock line 5 and opens.The plug that blocks water is established an air chamber 7 below 6, sets firmly the ventilating pipe 8 that communicates with air chamber 7 above, and ventilating pipe 8 other ends are connected with the air vent 10 of the pedestal lower end of clutch for clutch control seat 9; Clutch for clutch control seat 9 one sides are hollow garden pipe, the sheathed overflow pipe 3 top predetermined positions that are fixed on, and opposite side is to have the pedestal that runs through air vent 10, articulates clutch Button Block 11 on the pedestal; Air vent 10 on the clutch Button Block 11 is controlled by clutch cramp 12, and clutch cramp 12 intersects pivot joint mutually with affecting sheet 13, affects sheet 13 tops to be installed in clutch backguy 14 1 ends, and the below has arc hook 131, can collude in clutch Button Block pedestal lower end; Clutch backguy 14 other ends are fixed on 16 places, bottom, sub-push switch 15 axle center; Sub-push switch 15 places push switch 1 inboard headspace, its afterbody be enclosed within articulate pipe (drawing among the figure) but on be the pivot state; Swim the spacer 162 of seat 16 side articulated section 161 by spacing block set 9 controls of clutch for clutch control seat 9 pedestals below, seat 16 the opposite side of swimming is a water floating chamber 163, there is a convex clip 164 water floating chamber 163 tops, can upwards lean clutch cramp 12 belows of interlock clutch Button Block 9; The also default push rod 165 in water floating chamber 163 tops can interlock on the push rod 165 leans the convex clip 132 that affects sheet 13 tops to establish of clutch Button Block 9.

When thinking that use is washed by water more on a small quantity, depress push switch 1 connecting rod 4 and drive interlock lines 5, the plug 6 that blocks water is pulled upwardly, the bath outlet that the interior water of water tank this moment is filled in 6 belows through blocking water is flowed out, for flush toilets.The air vent 10 that seat 16 makes the clutch cramp 12 of the clutch Button Block 11 that these water floating chamber 163 top convex clips 164 of swimming seat are leaned break away from clutch for clutch control seats 9 relatively along with drawdown pedestal top runs through of swimming this moment, make air chamber 7 be filled water, plug covers downwards because the weight of water will block water, no longer feed water, reach the purpose of water-saving.

When need during with big discharging quantity of water, then push sub-push switch 15, connecting rod 4 drive interlock lines 5 tail ends are pulled upwardly the plug 6 that blocks water and make the interior water outflow of water tank on the one hand, the top of the backguy of clutch simultaneously 14 pulling clutch Button Blocks 11 affects sheet 13 displacement laterally, the air vent 10 that the pedestal top that makes clutch cramp 12 cover clutch for clutch control seat 9 is just run through affects 131 on the arc hook of sheet 13 belows to be stuck in outside the pedestal of clutch for clutch control seat 9.Seat swim this moment 16 also along with water level is moved to minimum point downwards, treat to rise along with the water level of the water of water supply system subsidiary water tank again after water in the water tank is gone out in a large number and set back gradually.
