Description

Wc flushing cistern

The present invention relates to be specially adapted to the wc flushing cistern in lavatory.

Certainly, the toilet tank flush systems of many different types being arranged is that everybody knows.In order to help water saving, most of rinse-systems of design have a kind of idea at present, after giving fixed flushing generation, just the water intaking valve of water tank is opened, allow supplementing water enter in the water tank exactly, do not have any additional fresh water waste in the middle of flushing.

In known water tank flushing system, washing water quantity in the import feed water valve control water tank when stopping as if the import feed water valve, does not give fixed water level and reach in the water tank, and this process causes producing invalid flushing action in urinal.If in water tank, often keep enough hydraulic pressure, utilize other device of control washing water quantity simultaneously, then can more effectively use more a spot of water to clean urinal.

If this system is such arrangement, more favourable situation will appear.Promptly the water outlet of water tank valve fails normally to cut out for some reason, causes water slowly to bleed in the urinal of lavatory with linking, at this moment water intaking valve feed tank supplementing water not.If can obtain this situation, then do not have the phenomenon of wasting water.

The present invention seeks to provide a kind of water tank flushing system with these premium properties.

Rinse-system provided by the invention comprises a flusher and the water tank that is filled with water that water inlet and delivery port are arranged.Flusher comprise a hollow section and by hollow section with a closure member, this pipe moves between the position of opening and closing in water tank, this therebetween closure member open and close delivery port respectively, wherein also comprise and to handle the device that this pipe is shown in an open position, so that make water tank that the effect of flushing take place.Buoyant device on this pipe keeps under buoyancy function on the position that this pipe opening, and till giving fixed flushing and finishing, after this buoyant device loss of buoyance makes this pipe get back to its fastening position again.A water intaking valve that is used to control water tank inlet is arranged, and the characteristic of this valve makes control lever depart from the position that water intaking valve is closed.On float pole with cursory pivoted on control lever, on cursory, a hook is arranged, and a retainer is arranged on hollow section, when hollow section is got back to its fastening position, retainer is meshed with hook, float pole moves simultaneously, like this, control lever is moved on the position, and water intaking valve is opened in this position, thereby supplementing water is entered in the water tank, when the water that injects water tank reaches when giving fixed water level, its result, control lever unclamps when moving to the deviation position that water intaking valve closes, and the cursory of arrangement is separated from hook from retainer thereupon.

The water that is preferably in injection reaches when giving fixed water level, and the cursory and control lever of new equipment contacts, and keeps it simultaneously on the fastening position of water intaking valve.

When being preferably in its fastening position, the inside of pipe communicates with delivery port, and an opening that is used for overflow is arranged on the pipe, allows excessive water to flow out by pipe and delivery port from water tank.

Cursory device can be that a movably inverted tubular is cursory, is engaged on the pipe by friction.

Fig. 3 is the sketch of water tank inside in the expression flushing process;

The sketch of water tank inside when Fig. 4 is expression flushing end;

Fig. 5 is the fragmentary, perspective view of a working lever of explanation;

Fig. 6 is the sectional view of expression water intaking valve.

The interior cross section of the water tank of representing among Fig. 1 10 from its top to the bottom diminishes gradually.One vertical antetheca 14 is arranged at top 12, its parallel its rear wall, and also

sidewall

16 and 18 is restrained downwards.Top 12 and bottom 20 adjacency, lower vertical rear wall are that the extension of top rear wall forms, and antetheca 22 is restrained downwards towards rear wall, and sidewall 24 and 26 is restrained downwards.Water tank wall has an independent lid 27 simultaneously by the plastic monoblock casting forming, and it covers the top at upper side wall.

Water inlet pipe 30 with a routine between from the water source to the water tank connects, and the outlet pipe 32 that a routine is arranged is by extending to urinal at the bottom of the water tank.Washed handle 34 stretches out from lid 27.

Fig. 2 is illustrated in and promptly washes the beginning inner case of water tank before under the normal condition.Do not have expression among the water inlet pipe 30(figure) link to each other with the entrance point of water intaking valve 36, the characteristic of water intaking valve will describe in detail below.Basically it have a specific character promptly when closing by means of intake pressure.A control lever 38 is installed on the pivot of valve body, because the spring adorned makes control lever setover in the direction of the clock (as shown in Figure 2) in the valve body.Flow into water tank in order to open water intaking valve by water, control lever 38 must rotate around pivot by the counter clockwise direction among Fig. 2.

At the center position of water tank bottom 40 an outlet accessory 42 is arranged, stretch out in the centre bore of the screw nipple 44 on the outlet accessory from water tank 10 bottoms 40.The outlet accessory comprises that one is contained in the end flange 46 that has centre bore on the water tank bottom 40 and is used for supporting upper flange plate 48 and has the upstanding edge 47 in gap.Upper flange plate 48 has a centre bore, is used for installing a hollow section 50, and a rubber seal 51 is equipped with in the lower end of hollow section.Hollow section 50 can freely slide in the pilot hole of upper flange plate 48, and in use, the outlet pipe 32 among Fig. 1 is linked in the microgroove connecting tube 44.The inside of hollow section 50 communicates with the inside of outlet pipe 32, thereby also communicates with the urinal that uses water tank.

Be inverted bowl-shape cursory 52 and hollow section 50 for one and form very tight interference fit, yet it can move up and down with hollow section 50 on request.The upper end that is fixed on hollow section is a back-up ring 54, and it has the flange 56 that extends down.Pass and form a hole 58 on the wall of hollow section 50, just in time on back-up ring 54.

What freely rotate on the not end pivoting of control lever 38 is a common L shaped bar 60, and it has a hook-shaped hook 62 that stretches out.Be fixed on from the garden shape shown in Fig. 2 to Fig. 4 cursory 64 on the not end of L shaped bar 60.When water tank is full of water, as shown in Figure 2, on the cursory surface that is suspended in water, and control lever 38 applied upward pressure, so that keep water intaking valve 36 in its closed condition, the spring in the promptly cursory assistance valve body makes valve closing.

When the flushing beginning, lift handle 34 up, rubber seal 51 is removed from end flange 46, at this moment water flows out water tank rapidly by the direction shown in the arrow among Fig. 3.Along with the water tank middle water level descends, cursoryly under action of gravity, land, below hook 62 back-up rings 54 that come on the hollow section 50 till.

The shape of water tank will be accelerated flushing speed.Reason is because water tank is taper on the one hand, causes delivery port place current unimpeded.Reason on the other hand is because water tank has high narrow shape, and this just means to have good Static Water potential difference when the flushing beginning.

In flushing process, put because the effect of the air capacity 62 that contains in the floating drum 52 makes air hose 50 remain on lifting zone, and water below reaching on every side, floating drum 52 flows.When the water level in the water tank greatly when dropping to the upper surface position of floating drum 52, the floating drum loss of buoyance, the rapid decline of hollow section at this moment makes rubber seal 51 get back on the base of flange 46 again.Therefore washing water quantity is determined by the position of the floating drum on the hollow section 50 52.By adjusting the floating drum position on the hollow section, just can change the washing water quantity of new needs.Although not expression among the figure can be at the outside calibrate of hollow section 50, thereby makes the accurate adjustment of needed washing water quantity become more convenient.

When hollow section 50 fell to making rubber seal 51 returns, back-up ring 54 was with hook 662 engagements and rest on the there, pulls down control lever 38 water intaking valve 36 is opened.Supplementing water 66 flows in the water tanks 10 at this moment.Only it should be noted that supplementing water just begins to flow in the water tank after flushing finishes.

When the water in the water tank was full of once more, the water of rising ran into cursory 64 and its is risen at last.L shaped bar 60 pivots by the counter clockwise direction shown in the figure, thereby makes hook 62 throw off back-up ring 54.Cursory then takeofing suddenly supported the bottom of control lever 38, upwards pushes control lever, and water intaking valve 36 is closed.Therefore, before flushing generation next time, the spring in the valve body and the acting in conjunction of buoy make water intaking valve 36 keep closing.It is malfunctioning promptly to lose spring, and the independent cursory water intaking valve 36 that also can make keeps its closed condition.

Hole 58 on the hollow section 50 is as overflow.If rinse-system is malfunctioning for a certain reason, at this moment the water intaking valve on the water tank 36 is in open mode, so excessive water just can ostium 58 in, along hollow section 50 in the dirty lavatory urinal of going forward side by side.

Also should be noted that: if rubber seal 51 not on correct position, its result causes water tank to leak continuously, and water intaking valve 36 remains and closes, just its sample does not continue supplementing water, also just can leak with stopping.

As previously described, when upwards lifting handle 34, begin flushing.Water tank 10 also may occur and be fixed on the too situation of high position, for example on its fixing elevated position on the wall, with manual operating handle inconvenience.

Fig. 5 represents the improvement to said apparatus, is applicable to this situation.In this drawing, with a tack carefully follow closely part 74 the collar 70 be fixed on one firm tightly on spring 72.Utilize horizontal stub shafts 78 that the collar 70 is supported on the horizontal axis of U-shaped frame 76, the collar 70 is rotated around horizontal axis.

One end of spring has a hook 80, and it is fixed in the groove 82 of handle 34.The other end of spring also has a hook 84.When the spring of the end with hook 84 was drop-down, handle 34 rose, thereby began flushing.But, because the use of spring, not vertical when drop-down even have an end of hook 84, its special location and supporting way can guarantee that also handle 34 rises.On the practical work,, handle 34 is risen when the not end of spring during towards any one direction motion.Because when a user when non-perpendicular direction applies pulling force to spring, can not cause damage to the part of handling, so it is compared with the rigidity washed handle, be considered to an outstanding advantage.

Even be difficult for touching the occasion of spring at user's hand, and to hang oneself one from hook 84 as far as possible and restrict or a chain, its lower end handle is on the suitable height, and is easy to use.

Fig. 6 does more detailed explanation to water intaking valve 36.It comprises a consent 100, an inner chamber 102 and a water inlet 104 that passes the sidewall 18 of water tank 10.There is a delivery port 106 down in this chamber, and its upper end is sealed by a microgroove connector 108, and the mobile of it guarantees that inner part in addition is in contact with one another.

Microgroove connector 108 has a blind bore 110, and an end of compression spring 112 just is installed in wherein.An other end bearing of spring 112 is on the axle collar on the pivot 116 114, and pivot freely moves up in hole 110.The mode of the slip of the bottom of pivot is passed a valve body 118, and terminates in one and become on the big end 120.Have a round ring 112 on the valve body 118, and in the groove of the upper face of valve body, second round ring, 1240 control levers 38 are housed and turn to consent 100 places around pivot 125.

As shown in the figure, when water intaking valve was in the closed position, spring 112 came on the round ring 124 axle collar 114, and round ring 122 then comes on the shoulder 126 of consent 100.When control lever 38 moves by being directed downwards of arrow 128 (as previously mentioned), the not end of control lever 38 rises pivot 116, and its result makes the axle collar 114 displacements and the pressure in the chamber is descended.Secondly, becomes big end 120 jack-up valve bodies 118, thereby open valve fully, make makeup water stream go into water tank 100 after power disappearance downward on the control lever 38, on the position when it is got back to valve body again and closes under the elastic force effect of spring 112.
