Big parts described in first embodiment of the present invention are to use the thermo-plastic polymeric material, and preferably polypropylene, polyethylene or ABS adopt molding process to make.

A container 3 as shown in Figure 1, has a vertical rear wall 4, two from top to bottom intilted

sidewalls

5 and 6, as shown in Figure 2 and an intilted antetheca 7.The both sides of the bottom of container 3 are recessed by the relative along continuous straight runs with 6 of sidewall 5, form bottom parts 8 and 9.

Bottom parts

8 and 9 respectively accounts for container 3 at 1/4th of the width of this position, thus container 3 is divided into storage tank 10 and following flushing tank 11.The volume of flushing tank is by the bottom of rear wall 4, continue again after recessed significantly by

sidewall

5 and 6 part 5 of continuity downwards ' and 6 ', the extendible portion of recessed a little antetheca 7 and bottom 12 limit.Bottom 12 is tilted to the center slightly by sidewall, and a weep hole and outlet pipe 13 are arranged in the centre, and outlet pipe 13 is Unitarily molded with container 3, and can be assembled in the jet water spout 14, as shown in Figure 2.Jet water spout 14 preferably includes a venturi sleeve pipe, and its position is close to the outlet of outlet pipe 13, the flow velocity when being used for increasing water and leaving flushing tank 11.

Flushing cisterns 11 and storage tank 10 are that the dividing plate 15 by a loose fit separates.Fig. 4 illustrates in greater detail the structure of dividing plate, and dividing plate 15 is made of a rectangular flat 16 with smooth fillet.The edge part on plane has thin flexible flanges 17 on dull and stereotyped 16, preferably about 0.2 millimeter of the thickness of this flange 17, and width is at least 2 millimeters.When dull and stereotyped 16 are pressed into, withstand the bearing 18 of the corner part formation of

wall

4,5,6 and 7, guaranteed good sealing.Allow a spot of leaking between storage tank 10 and the flushing tank 11, this does not influence the service behaviour of water tank.This production method can be avoided the excessive demand to the tolerance dimension of container 3 and dividing plate 15.

The formation of bearing 18 partly is made of the transition level shoulder 19 between the recessed wall 7 in the bottom of antetheca 7 and pipe, partly by

bottom

8 and 9 and the extendible portion 5 of sidewall ' and 6 ' between

transition shoulder

20 and 21 constitute.Muscle 22 connects rear wall 4 by base 12 and stretches to the flushing tank top.Muscle 22 is parallel to each other and equidistant arrangement, preferably is inclined upwardly to strengthen the intensity of base 12.For the support that dull and stereotyped 16 formation are added, the last plane of muscle 22 is identical with the height of

shoulder

19,20,21.Muscle 22 removes above-mentioned effect and also has other many effects, and they play booster action to the sidewall of container 3, for example, keeps the shape invariance of sidewall when the 10-31 premium on currency is poured into rapidly, also can help to guide water to flow into outlet pipe 13 by flushing tank 11.

The general reinforcement that helps of various recesses that container 3 forms when molded and shoulder part, the wall thickness than without this kind reinforcement the time can be thinner, also saved the polymeric material of molded usefulness.Various intilted walls or inclined-plane have all increased intensity, make container 3 can store a large amount of water and indeformable or destruction.

The last plane of

shoulder

20,21 and adjacent base divide the difference in height between 8,9 to be approximately 7 millimeters, and dull and stereotyped 16 thickness is preferably 3 millimeters.These sizes assurance flanges 17 are close to the facade part of

shoulder

20 and 21 after this regional bending.Dull and stereotyped 16 also are close to rear wall 4 and antetheca 7, and a kind of good sealing is provided.Can find out that from the shape of flange when dull and stereotyped 16 were depressed, flange 17 was bent upwards, this and way of contact wall will stop the dull and stereotyped motion that makes progress.Have fillet by the formed bearing of shoulder part as can be seen from Figure 3, these fillets match with the fillet of flat board 16.

Container 3 preferably hangs with two

special suspensions

23 and 24, as shown in Figure 2, they stretch out the top of storage tank 10 and below, and have one " U " shape section.Each suspension has the fixing hole that a slotting screw, hook or other fastener are used.The rear wall 4 of two suspensions and container 3 is Unitarily molded, so not only provides the method that hangs also to strengthen the intensity of rear wall 4.Two ends that suspension stretches out downwards

part

8 and 9 of being gone to the bottom separates, but this is unimportant, because container is a molding process manufacturing.

According to most preferred embodiment of the present invention, the major part of suspension or the section of mid portion be " H " shape preferably, the leg of " H " shape outside container is more a little than the short legs that is positioned at internal tank, and the end sections of suspension be can't see two short-legs of " H " shape in the drawings, because they are filled the ability of gaining in strength with holding capacity.Above-mentioned two short-legs are not shown in Fig. 3, because it being covered along 26 of stretching out of edge, container 3 top.

Strengthen the intensity on 3 containers, 3 tops and support cover plate 27 along 26.Cover plate 27 is preferably narrower, and about 50 mm wides are it plays a complete cover plate effect not as talking about guiding and supporting role.Cover plate 27 is suitable for reading across container 3, as shown in Figure 1, and 4 tensions of antetheca 7 and rear wall is in the same place, for this purpose, two

projections

29 and 30 are arranged at the cover plate bottom, protrude downwards to touch rear wall 4 and antetheca 7, and the surface of projection 29 slopes inwardly to cooperate the inclined-plane of antetheca 7.This projection is embedded with threaded brass lining 31, and screw 32 is penetrated by the hole 33 of antetheca 7, is screwed on the brass lining 31.

Projection 30 a preferably tabular bossing has hole 34, makes screw 35 can pass from the inside of storage tank.These screws cooperate with nut 36, from recess 37 top nuts of the external surface of rear wall 4.Rear wall 4 is thicker at the wall thickness at recess 37 places.In order to penetrate threaded screw, each recess all has a hole 38.When container was filled water, cover plate 27 has resisted because the power that the wall 4 and 7 that the weight of water causes expands outwardly.Cover plate 27 has a longitudinally beam 39 Unitarily molded with cover plate, and as shown in Figure 5, beam 39 is positioned in the middle of the cover plate, and two and

projection

29 and 30 connect together, in the middle of be moulded a guideway 40, the effect of guideway 40 will be narrated in the back.The upper surface of cover plate 27 has a rocker bearing 43, half place of distance between projection 29 and guideway 40.Rocker bearing 43 is looked down from above and is preferably " I " shape, and the soffit of girder is across cover plate 27, and shown in the dotted line among Fig. 5, Liang Yi is inclined upwardly, as shown in Figure 1.

Bearing 43 is to establish in order to support rocking bar 44, the rocking bar section is preferably one and falls " U " shape, 45 of the mid portions of the soffit of girder are on bearing 43, the inner surface on the edge of a wing 46 is against the longitudinal edge portions of cover plate 27, thereby rocking bar obtains simple on rocker bearing and effective support and guiding, there is the upper end of 47, one flush lever 49 in a hole to pass this hole in the rear end of the rocking bar soffit of girder and is inserted in handle 48 again.Handle 48 can be loaded onto when rocking bar is installed, and the hole insertion bearing that also can earlier the least significant end of flush lever be passed rocking bar refills rocking bar and handle.

The bottom 15 of dividing plate, as shown in Figure 4, the weight of the water above during bath and supplementing water, will bearing in the storage tank, for this reason, the last plane of dividing plate bottom 15 has reinforcing rib 50, and the muscle of protrusion is with dull and stereotyped vertical, from being positioned at middle guideway 51 radiation-like of dividing plate along reaching flange 17.Reinforcing rib 50 tilts, its low side directed flange 17, guideway 51 also and between the flush lever leaves a ring-type the air gap around flush lever, remove and also have a little bearing holder (housing, cover) 52 in addition, it occupies the passage of guideway 51, extend to the place of 1/2nd height of about guideway 51, have a hole to be used in the middle of this bearing holder (housing, cover) 52 to center position but allow it to slide up and down of flush lever 449.The top of guideway 51 has a counterbore 54 to be used for holding the low side of an interior air chimney 55.Air chimney 55 extends vertically up to the top of container 3 and passes the guideway 40 of cover plate 27.The internal diameter of air chimney is at least the twice of the diameter of flush lever 49.

Flush lever 49 is surrounded with storage tank 10 by air chimney 55 and is isolated fully, as shown in Figure 1.

Bearing

41 and 52 makes flush lever keep concentric with air chimney 55, and air chimney 55 tops are by the ventilation hole 42 and outside air circulation of guideway 40 inside of plate 27.The low side of air chimney 55 is communicated with flushing tank 11 by an escape pipe 56.Escape pipe 56 stretches out from the inside of guideway 51 near the upper end, slopes downwardly into the place of dividing plate 15 near rear wall 4, stops at 15 lower plane of dividing plate.Escape pipe 56 is also strengthened the intensity of dividing plate 15 as reinforcement.The internal diameter of escape pipe 56 should be with the same big with the internal diameter of the air chimney 55 of its connection.Ventilation system comprises: air chimney 55 and escape pipe 56.When discharging water flushing, air enters flushing tank 11 and occupies the original space of water.When needing again supplementing water after the bath, ventilation system is discharged air flushing tank 11 again.This special tectonic makes the water that the time enters air chimney 55 and escape pipe 56 in bath reduce to minimum, and this feature is very important because when supplementing water owing to ventilation hole 42 is gone out in the effect of power.In the final stage of supplementing water, water will rise to and the same horizontal plane of storage tank by air chimney 55 and escape pipe 56, but can what not surpass again, thereby can not go out air chimney 55.And what need prevent is not allow water enter

pipeline

55 and 56 prematurely when giving flushing tank 11 supplementing water.

Dividing plate 15 comprises some limberss 57, is not having to allow water to flow to flushing tank 11 from storage tank 10 under the blocked situation.A boss is all arranged at the bottom of each limbers 57, limbers 57 be positioned at guideway 51 around, between muscle 50.In most preferred embodiment, there is not the limbers between the muscle after two of escape pipe 56 bottoms, what replace them is small boss 60 around guideway.These boss 60 are the same with the height of boss 58.The gross area of limbers 57 should make that the water of flushing tank 11 can be replenished in 5～60 seconds, preferably 5～15 seconds.From view of function, the time of supplementing water that yes is short more good more, but the time of supplementing water is long more, and the diameter in hole 57 can be more little, they is blocked up also more or less freely when bath.

Draining and supplementing water for control flushing tank 11, a valve system is set, in first embodiment, this system comprises the valve disc 59 that an energy slides in the bottom of flush lever 49, it is installed in flush lever 49 and stretches out the place that dividing plate 15 bottoms enter flushing tank 11, spacing snap ring 61 of these valve disc 59 usefulness limits it and moves upward, and also can realize with other similar device that is attached on the flush lever 49.In order to guarantee rigidity, the lower plane of valve disc 59 has a cover or the axis of guide 66, be connected on the valve gap 64 to the bottom rigidity of flush lever 49, compression spring 62 has been installed between the lower plane of the upper surface of valve gap 664 and valve disc 59, and compression spring 62 remains in the groove 63 of lower plane of the recess on last plane of valve gap 64 and valve disc 59.In order to guarantee that outlet pipe 13 has good sealing, valve gap 64 is pressed on the water tank bottom mouth by an additional compression spring 67, and compression spring 67 is around flush lever 49, pressure is applied on the recess of the top of valve disc 59 and guideway 51.As shown in other embodiment also can only according to the amount of relying on for support make valve gap be pressed in outlet pipe 13 above.

According to the present invention, when water closet was filled water and remained static, flushing tank and storage tank all can be filled water.Compression spring 11 is pressed in valve gap 64 above the bottom 12 of flushing tank 11, covers outlet pipe.When wanting to discharge water flushing, rocking bar 44 is depressed, rocking bar 44 is swung on the fulcrum that rocker bearing provides, on the lower surface of its distant place end points and the handle 48 on the flush lever engages, continuation applies power on rocking bar 44, flush lever 49 and will be lifted with the related valve gap of flush lever, thus the water in the flushing tank 11 are flowed out rapidly, under action of gravity, the water of water tank is discharged from outlet pipe 13.When being flowed out by flushing tank 11, casing is replaced by the air of equivalent, and air is entered through air chimney 55 and escape pipe 56 by the outside.

When rocking bar 44 touched cover plate 27 surperficial, its stroke was restricted, and at this moment the last plane of valve disc 59 will be pulled to the lower plane of dividing plate 15, blocks limbers 57, thereby stoped water to flow into flushing tanks 11 from storage tank 10.Thrust below the valve disc applies by spring 62 from valve gap 64.

When rocking bar 44 was released, flush lever fell under the effect of spring 67, and valve gap 64 newly covers outlet pipe 13.Valve disc 59 is not stopping up limbers 57, and water is gone into flushing tank 11 from storage tank 10 by these orifice flows under action of gravity.Air in the flushing tank 11 will be discharged by air chimney 56 and escape pipe 56 by the identical approach of coming in, and the time that flushing tank 11 is filled water is decided by the area of limbers 57 and the water yield in the storage tank 10.

In second embodiment of the present invention, to shown in Figure 9, water tank container and other big parts are that pre-standby thermoplastic plastic board is made by vacuum forming process as Fig. 6.Preferably use the high polystyrene of resistance to impact, as a rule, the parts in addition of second embodiment are identical with other parts of first embodiment, so the reference number of usefulness is also identical.
