Abstract

The utility model discloses a water discharging controller of a toilet washing device, which is mainly characterized in that an actuating rod moves up to grips under two arc hinges, and the grips can fasten the actuating rod from open pores above the steps of the actuating rod. Water storage on the upper part can continuously flow down toward the lower part through middle holes. When the water storage is drained away, under the action of self weight, the actuating rod forces the grips of the two arc hinges to disengage from the open pores of the actuating rod; then the actuating rod falls down, meanwhile, a cushion ring blocks the middle holes, and the shoulder of the actuating rod seals a through hole. Compared with the existing device, the device can drain the water storage to a water outlet in one time with good sealing property.

F, an actuating rod are stairstepping, have a hole above ladder, and stretch out downwards by the central siphunculus of above-mentioned circular lid the lower end of this actuating rod, and the shoulder of actuating rod is positioned on the above-mentioned packing ring;

G, a nut are tightened in the bottom of above-mentioned actuating rod, and make this nut by and be in the central openings place of above-mentioned support;

H, a cross bar are fixed in the top of above-mentioned centre bore portion, and centre has a perforate on it, and the upper end of above-mentioned actuating rod is protruded upward by this perforate;

I, two arc hinges all have a gripper below it, and this two hinge is loaded on the both sides of above-mentioned cross bar respectively, and the gripper that makes above-mentioned actuating rod be moved upward to the certain altitude hinge can fasten actuating rod from the perforate of actuating rod ladder top;

But J, the mechanism that the control action bar moves up.

This device is when mechanism action that the control action bar moves up, actuating rod will move up, make the actuating rod shoulder leave packing ring earlier, at this moment liquid will be discharged from the through hole of circular lid, with rear nut with circular lid jack-up, liquid changes into from centre bore portion and flowing out, meanwhile, actuating rod continues to be moved upward to that perforate position is fastened by the gripper of hinge on it, because this moment, hinge was subjected to from top to down working fluid effect, made hinge remain closure, thereby the guarantee effect bar is fastened and is not come off, liquid just rushes at the bottom from top by centre bore portion continuously, when liquid drained, actuating rod was thrown off the hinge gripper on the contrary and is fallen under action of gravity, and circular lid and packing ring are blocked centre bore portion, the shoulder of actuating rod reaches the draining of control outfall with the sealing of the through hole on the circular lid.

Fig. 1 is a kind of concrete structure sectional view of the utility model;

Fig. 2 is the schematic diagram that the two arc hinges of Fig. 1 are loaded on the cross bar both sides.

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to device shown in the drawings, comprise tubular shell, circular lid 1, packing ring 2, support 3, actuating rod 4, cross bar 5, arc hinge 6, the mechanism that nut 7 and control action bar move up, wherein, there is the little centre bore portion 8 of a relative aperture housing internal diameter at the internal cross section place of described housing, the centre of described circular lid has siphunculus 1a, be distributed with through hole 1b on every side, described packing ring 2 inlays above-mentioned circular lid 1 in wherein, and place in the above-mentioned centre bore portion 8, described support 3 is fixed in the below of above-mentioned centre bore portion 8, centre has a perforate on it, described actuating rod 4 is stairstepping, above ladder, have a hole 4a, stretch out downwards by the central siphunculus 1a of above-mentioned circular lid the lower end of this actuating rod, its shoulder then is positioned on the above-mentioned packing ring 2, described nut 7 is tightened in the bottom of actuating rod, and make this nut by and be in the central openings place of above-mentioned support 3, described cross bar is fixed in the top of above-mentioned centre bore portion 8, centre has a hole on it, and the upper end of above-mentioned actuating rod 4 is protruded upward by this hole, described two arc hinges 6, one gripper 6a is all arranged below it, this two hinge is loaded on the both sides of above-mentioned cross bar 5 respectively, and the gripper 6a that makes above-mentioned actuating rod 4 be moved upward to certain altitude hinge 6 can fasten actuating rod from the perforate 4a of actuating rod ladder top.
