Water can not enter the partial inverted U-shaped tube which passes through a water outlet to ensure that the leak phenomenon can not occur. The water can be saved.

Description

Wc flushing cistern

The utility model relates to a kind of flushing device, relates in particular to a kind of wc flushing cistern of flush toilet.

At present, existing toilet flush mostly is plug mouthful formula, and drainage in use takes place easily, causes the waste of water, and ground, tool lavatory often is in the wet state of filtering.It is multiple to cause the reason of leaking to have, and one of them is that rubber stopper is aging, the elasticity variation, and perhaps the material of rubber stopper is bad, makes its distortion inhomogeneous, so all can cause rubber stopper can not seal up delivery port effectively.Have again,, particularly use after a period of time because processing and the error installed cause well centering of rubber stopper and delivery port, the two neutrality is become poorer, leak and cause.

Along with the great development of industrial or agricultural and improving constantly of living standards of the people, China's daily water consumption increases year by year.Yet shortage of water all appears in China many cities, especially metropolis, the situation that water day is becoming tight.Therefore, water saving is the due responsibilities of national people.When improving whole people's using water wisely consciousness, if can take the otherwise effective technique precautionary measures, eliminate unnecessary water wasting phenomenon from every side, this will play an important role to water saving.

The purpose of this utility model is to overcome the above-mentioned deficiency of existing flushing device, particularly toilet flush, and the wc flushing cistern of the leakproof of a kind of energy, water saving is provided.

Wc flushing cistern of the present utility model, comprise water tank, tank lid, float system, the inverted U-shaped shell that places water tank and its internal activities member, described inverted U-shaped shell have inverted U-shaped tubular portion and with one of the tank that is connected of end, position in the bottom of tank away from inverted U-shaped tubular portion is provided with outlet nozzle, and is stamped the outlet nozzle cap on this outlet nozzle; Described internal activity member comprises arm-tie with inlet opening, place this pliable and tough lamination above arm-tie, place the force-applying member on this pliable and tough lamination, and the pull bar with crossette that passes from three central authorities.

Wc flushing cistern of the present utility model, wherein said tank are rectangular box body, and are provided with reinforcing rib between inverted U-shaped tubular portion and rectangular box body tank; Described force-applying member can be a helical spring, also can be pouring weight; Described pull bar can be the external pulling type pull bar that passes tank lid, and its outer upper ends is fixed with handle, also can be the interconnected pull bar, and its upper end ends in the water tank, and there is the backguy hole end thereon.

Wc flushing cistern of the present utility model, its advantage is: substituted plug mouth formula rubber stopper in the existing water tank with inverted U-shaped shell and its internal activities member, therefore, when the water tank topped up with water, certain distance is arranged at the height of water level in the water tank and the top of inverted U-shaped tubular portion, and the water in the tank can not enter in that part of pipe that inverted U-shaped tubular portion links to each other with delivery port.Like this, just guaranteed drainage not to take place, thereby saved water.

Below in conjunction with accompanying drawing, wc flushing cistern of the present utility model is described in detail.

Fig. 1 is the structural representation sectional view of an embodiment of wc flushing cistern of the present utility model.

Fig. 2 is the vertical view of an embodiment that the arm-tie of inlet opening is arranged in the wc flushing cistern water tank shown in Figure 1.

Fig. 3 is the elevation of interconnected pull bar in the wc flushing cistern water tank of the present utility model.

As shown in Figure 1, wc flushing cistern of the present utility model comprises water tank 1, tank lid 2, float system 3, the inverted U-shaped shell 4 that places water tank 1 and its internal activities member.Wherein water tank 1 and tank lid 2 are plastics, also can be pottery or other materials.Inverted U-shaped shell 4 has inverted U-shaped tubular portion 5 and rectangular box body tank 6, be provided with reinforcing rib between the two, and the two is connected.Position in the bottom of rectangular box body tank 6 away from inverted U-shaped tubular portion 5 is provided with outlet nozzle 7, is stamped outlet nozzle cap 8 on it.Installed arm-tie 9, pliable and tough lamination 10, helical spring 11 and the external pulling type pull bar 12 that the inlet opening is arranged in the inside of rectangular box body tank 6.Pliable and tough lamination 10 is a flexible plastic sheet, and it places above the arm-tie 9 of inlet opening, and external pulling type pull bar 12 passes the central authorities of the arm-tie 9 and the pliable and tough lamination 10 of inlet opening, and suit helical spring 11 thereon.Two ends at helical spring 11 are provided with supporting slice.External pulling type pull bar 12 has crossette, and the part of shaft is processed with screw thread.By being contained in the pad and the nut of pull rod screw part, can regulate the position of arm-tie 9 in rectangular box body tank 6 of inlet opening.Pull bar 12 passes the hole on the tank lid 2, and back cushion sheet and nut are sealed the hole on the tank lid 2, and will shake hands 13 to be fixed on the outside termination of pull bar 12.Handle 13 can be trapezoidal for hollow, hollow rectangle, hollow square or annular, also can be hook shape.The pipe that does not directly link to each other with tank of the inverted U-shaped tubular portion of inverted U-shaped shell enters outlet pipe by the delivery port of water tank, and is fixed and seal by sealing mat and nut.

As shown in Figure 2, the arm-tie that inlet opening 14 is arranged 9 in the tank 6 of wc flushing cistern of the present utility model is the hard rectangular slabs with eight triangle inlet openings 14, and it matches with the inside of rectangular box body tank 6, and can upper and lowerly therein move.The shape of inlet opening 14 also can be circle, rectangle, square or oval, and its hole count also can change, for example 4.

When its pull bar of wc flushing cistern of the present utility model adopts interconnected pull bar 15 (as shown in Figure 3), the length of interconnected pull bar 15 is about half of external pulling type pull bar 12, and at the other end away from the pull bar crossette, there is backguy hole 16 upper end when promptly the interconnected pull bar is in running order.Be connected with the manipulation device of existing water tank by backguy hole 16.Handle the outer handle of water tank, then can make on the interconnected pull bar 15 and move, thus with the arm-tie 9 that inlet opening 14 is arranged and on flexible sheets 10 move in tank 6.

Wc flushing cistern of the present utility model when adding water, when water flows into water tank, also turns over flexible sheets by the arm-tie 9 that the inlet opening is arranged and enters tank and be attached thereto in the pipe of logical inverted U-shaped tubular portion all around.When water was filled it up with, promptly float rose to when cutting out inlet valve, the distance at height of water level in the water tank and inverted-loop tube top, for water can not enter inverted U-shaped tubular portion not with pipe that tank directly links to each other in (see figure 1).Therefore, guaranteed the phenomenon of not leaking; When bath, use the handle (for the external pulling type pull bar) that pulls moving pull bar, or move or spur the outer handle (for the interconnected pull bar) of water tank, through manipulation device pulling interconnected pull bar with hand.Under this dual mode, pull bar drives the arm-tie that the inlet opening is arranged and moves in tank, and with the whole pipes that push away by inverted U-shaped tubular portion waterborne in the tank, towards people's toilet or lavatory, reaches the purpose of flushing from outlet pipe.After flushing finished, pull bar made the arm-tie of inlet opening be displaced downwardly to the bottom of tank in tank under the effect of helical spring or pouring weight.This moment, float was sagging, and the water tank water filling stops water filling after reaching full water state, prepares flushing next time.The direction that enters and flow out this wc flushing cistern of current is shown in the arrow among Fig. 1.
