The two control of automatically strong siphon water-saving toilet pan

Affiliated technical field

The utility model relates to a kind of water closet, especially can produce powerful siphon in good time, automatically, reaches the two control of the automatically strong siphon water-saving toilet pan that water saving washes down, and belongs to technical field of sanitary ware.

Background technology

At present, public known water closet is to be made of closet body and inner siphon bend, water tank and water inlet bath switching system thereof etc. thereof.Siphon bend is discharged section by siphon bend suction casing and siphon bend and is constituted.Though, siphon bend resistance has closed that foul smell emits in the sewer pipe outward, but siphon bend simultaneously also to a certain extent obstacle dash under just current smooth and easy and let out, just can force siphon bend to produce siphonage after must having the water of q.s to inject urinal, make big; just urine and dash that current are smooth and easy to be let out down; this moment is big; urine with dash just mixing of the existing certain degree of water; cause still have in the remaining sealing water a spot of big; it is residual urinate; medium-sizedly dash just that water needs 9 premium on currency; water-saving dash just that water also needs more than 6 premium on currency; if discharging quantity of water is insufficient; can not produce siphonage; big in the urinal then; urine and towards the slowly overflow and descending of just water, causes towards just difficult.Like this, just objectively caused present known water closet water supply volume bigger, can't economize on water, and dash just can not be very clean, and knot urine dirt easily in the siphon bend stops up easily, mouse worm and so on also climbs out of through siphon bend from sewer pipe easily.

Summary of the invention

In order to overcome existing water closet, just the water yield is few because of dashing, and causes siphon bend can not produce siphonage, dashes just difficulty, and wants to wash down, and just must produce siphonage, the relatively large water of then will using up, deficiencies such as waste precious water resource.The utility model provides the two control of a kind of automatically strong siphon water-saving toilet pan, no matter towards just the water yield is in a large number little, all can produce strong siphon automatically, accomplish to dash in the stool, little the dashing of urinating also can be economized on water more than half compared with 6 liters of water-saving water closets, and dash cleaner, and this water closet siphon bend is not tied urine dirt, anti-clogging, thoroughly stop the mouse insects to climb out of through siphon bend from sewer pipe, the two controls of pin hand, during the water yield is divided, I regulates, siphon dynamics and speed also can be regulated.

The technical scheme that its technical problem that solves the utility model adopts is: the suction casing of the siphon bend of water closet is opened up directly or opened up substantially directly, and from the direct pass-out closet body outer wall of not turning to a discharge section turning, opening part is provided with the capping that there is the aperture of band sealing ring at a center, the piston of a band connecting rod is set in the suction casing of this siphon bend, piston rod stretches out from the capping central small hole of opening part, and installing shop bolt additional near terminal position, it is the hole, garden of backguy that its end is useful on.And the pipeline of the discharge section of siphon bend was still by originally projecting forwardly to suction casing tube wall opening at the turning radian at turning or by certain radian, and formation communicates.The front lower place of the end of position is not provided with a fixed pulley when piston rod is extracted out, and the front upper place of the end of position is provided with a fixed pulley when piston rod is extracted out fully, and each is provided with one and two fixed pulleys again in the coaxial both sides of this fixed pulley.The side, back is provided with one and runs through axle under closet body, the axle two ends respectively are provided with a foot rest connecting rod, respectively hang a foot rest connecting rod return spring near the place, two ends on the fixed pulley axis that the front lower place of the end of position is provided with when piston rod is not extracted out, and hang on the foot rest connecting rod.Move 1.5cm in the rear box wall with water tank, on the back at the bottom of the water tank, leave three smooth crossed beam trunkings.Water buoyancy plug and bath duct little water buoyancy plug in the bath duct are set, in order to regulating the different amounts forever of dashing above the bath duct of water tank bottom surface.Water tank near before and after the position on top to a hollow movable axis is set, the front end of hollow movable axis is provided with the bath handle that connects the backguy of Water flushing for cistern switch, and two lever arms are fixed in the rear end of hollow movable axis: pull out lever arm with solid than soft drawn wire through crossed beam trunking, go up fixed pulley and link to each other with hole, piston rod end garden; Drawing in lever arm passes through crossed beam trunking, goes up fixed pulley, descends fixed pulley to link to each other with hole, the terminal garden of piston rod than soft drawn wire with solid.The rear end hollow position of hollow movable axis is drawn the backguy of Water flushing for cistern switch, links to each other with bath foot rest connecting rod end through crossed beam trunking, last fixed pulley.A garden slide opening is opened to upper/lower positions in stage casing at hollow movable axis, water tank is introduced in the backguy of Water flushing for cistern switch thus, forward and backward tank switch backguy 6cm place below hollow movable axis in the water tank links, a Water flushing for cistern switch backguy return spring is set the slick and sly hole under from junction to hollow movable axis, high and low two bath buoyancy go between separately beyond the Great Wall from junction, the backguy beyond the Great Wall of following lower buoyancy is pine slightly, the degree of pine will be equivalent to wash by water half of handle stroke.Major and minor two buoyancy tanks are set on the water inlet switch shaft arm of water tank, link to each other with downward closed 90 ° only hinge between two buoyancy tanks, its effect is: when dashing just without water tank water, and with secondary water directly towards urinal, then available piston pedal connecting rod is pulled on piston and is drained, and main simultaneously buoyancy tank is to bow under axially and do not cause water inlet switch to be opened intaking with the hinge.Main buoyancy tank links to each other with the buoyancy tank connecting rod that is fixed on hollow movable axis, buoyancy tank linking arm, can link mutually.On hollow movable axis, hang buoyancy tank lower position-arresting frame, be used for determining the falling-threshold position of main buoyancy tank.Its effect is: do not allow backguy and piston bear extra power.A upper and lower two-layer adjustment module shelf is set in water tank, configuration adjustment module on the shelf, the material that adjustment module and shelf are a bit larger tham water with proportion and are not afraid of water logging is made.Adjustment module support height adjusting knob is used for the configuration height of adjustment module.The effect of adjustment module is: when upper layer module configuration more for a long time, major and minor buoyancy tank descends fast when bath, comparatively fast draws up and washes by water fewly slightly thereby drive piston, draws up more slowly and washes by water more otherwise then drive piston.When the lower floor module is placed more for a long time, then the discharging quantity of water of only dashing in the influence is few slightly, otherwise the discharging quantity of water of then only dashing in the influence is many slightly, does not draw up speed but all do not influence piston.

When dashing urine, pull out about half bath handle or step on half bath foot rest connecting rod approximately, then pull out the bath handle during towards stool fully or step on bath foot rest connecting rod fully.Its operating principle is: make high or low bath buoyancy plug be in open mode by the bath backguy, during beginning is dashed in the urinal or little water, because drawdown in the water tank, the master on the water tank water intake switch shaft arm then, secondary buoyancy tank under the effect of gravity with drawdown, make buoyancy tank connecting rod with main buoyancy tank interlock, the buoyancy tank linking arm is interlock downwards also, because buoyancy tank connecting rod, pulling out of buoyancy tank linking arm and water tank back, drawing in lever arm all is to be fixed on the same hollow movable axis, to pull out lever arm up so can allow, it is descending to draw in lever arm, backguy by the piston rod end, piston is taken out synchronously at siphon bend, because piston just is fully immersed in the sealing water of siphon bend suction casing mouth originally, just drive sealing water and big; urine and part poured the just water that dashes of urinal; the discharge section to siphon bend flows; promptly in good time; as to produce syphonic water flow automatically; follow-up pour dash just that water will continue syphonic water flow; because big; urine is flowed out with the automatic siphon current in advance; follow-up what dash just water flushing is big; the urinal that urine has been flowed substantially; get along well greatly; mixing is arranged for a short time, thus follow-up totally dash cleaner that just water can dash urinal.After cistern water level descends, high or low bath buoyancy plug is closed under the effect of gravity automatically, at this moment because the water inlet switch shaft arm is descending, cause water inlet switch to be opened, beginning water filling in the water tank is because the water level rising, major and minor buoyancy tank is risen, owing to main buoyancy tank and buoyancy tank connecting rod, buoyancy tank linking arm, draw in lever arm and link,, can make piston push back to upper/lower positions slowly by backguy.When water tank is anhydrous,, then make piston be in uppermost position automatically, make siphon bend unimpeded owing to main buoyancy tank, buoyancy tank connecting rod, buoyancy linking arm, pull out the interlock of lever arm and piston, from but do not influence people with the water outside the water tank towards just.Water tank has water, but people then can step on the piston pedal rod and get final product need dash just with the water outside the water tank time.Because play rainbow automatically, it is just large and small then can to use less water just can wash down, it is more than half to reach water saving.Because under non-bath state, piston gets lodged in the suction casing of siphon bend, just can avoid the mouse worm and so in the sewer pipe to climb out of along siphon piping.Just piston is back and forth movable in siphon bend owing to dash at every turn, then the urine dirt of tying the dirty siphon bend suction casing of urine easily can be scraped off at any time, thereby makes it not tie the urine dirt.That piston and piston rod can adopt is high temperature resistant, the material of acid and alkali-resistance, wear-resisting wiping is made, as plastics, piston and piston rod can be made into hollow type, also can be at the inner light filling expanded material of hollow, the material that also available proportion slightly is lighter than water is made solid, like this since, because buoyancy of water can be cancelled out each other with the weight of piston and piston rod, will make piston be in suspended state like this, the frictional force of its motion greatly reduces, and it is more flexible to move.Main buoyancy tank need be made big buoyancy, big weight, for example to play the best motive force of rainbow be 3.5kg to piston guide, the minimum motive force of return is 0.5kg, then the buoyancy of main buoyancy tank just should manufacture 4kg, its weight manufactures 3.5kg, and the buoyancy of then main buoyancy tank output is that 4kg-3.5kg=0.5kg can make the piston return.When drawdown, the main buoyancy tank externally gravity of output is exactly 3.5kg, because this moment, buoyancy was zero, then the motive force that piston is applied just is 3.5kg.Also can regulate the buoyancy and the weight of main buoyancy tank as the case may be.

A spot of unnecessary water that surpasses the sealing water water surface can ooze gradually from the slit between piston and siphon bend and reveal, so the sealing water water surface in the urinal can remain at normal level in the urinal.Because piston is immersed in the sealing water, water itself has certain tightness, so piston can normally use under the situation of quite abrasion, so the application life of piston in theory should be quite long.Because the piston returning place force is about 0.5kg, when water in the urinal surpasses 0.5kg to piston pressure, then can push piston open, make siphon bend unimpeded, when water in the urinal to piston pressure during less than 0.5kg, piston i.e. return voluntarily.So also might cause urinal spill-over phenomenon to take place because of the existence of piston with regard to having guaranteed not.

The beneficial effects of the utility model are: 1, play rainbow automatically, in good time, dash in the stool, little the dashing of urinating, it is more than half to economize on water, and dash cleaner.2, no matter which kind of state is keeping siphoning installation all the time, emits foul smell never.3, because piston often moves repeatedly at the siphon bend suction casing of the easiest fouling and obstruction, piston will be wiped the urine dirt at any time off, make it never fouling.Also there is clogging hardly.Because, either obstruction goes down, or obstruction is released by piston.4, piston can normally use under the situation of quite abrasion.That is that water itself has certain tightness because piston is immersed in the sealing water.5, because piston rod is isolated because of piston and excrements, and the connecting rod outlet upwarps and sealing ring arranged, so do not exist dirt to ooze dew and the foul smell phenomenon of emerging.6, because piston stops up siphon bend under the situation non-dashing just, can effectively avoid mouse worm and so on to climb out of the people that feels sick from sewer.7, dash in the stool, the little water yield of dashing of urine and piston movement speed, strength, all can do certain adjusting by adjustment module.8, whole system does not have rapid wear, easy failed part, need not electromechanics, and is simple in structure, sturdy durable.As long as workmanship reaches a standard, then whole system 5-10 need not safeguard.
