The floor drain deodorant non-return its components narration for convenience that this closure is tight, water pipe section infraoral is set to Zuo Bankou and You Bankou by left and right directions, wherein, water fender is fixedly installed on left half mouthful, being sealed up on half mouthful of a left side, and bend pipe is installed on half mouthful of the right side of water pipe section, such water pipe section, water fender and bend pipe just constitute Semi-seal structure, sewage in water pipe section can only flow into bend pipe under the tuning guiding function of self gravitation and water fender, and flows out from bend pipe.For convenience of narration, the upper port of bend pipe being referred to as water inlet, the lower port of bend pipe is referred to as outlet, wherein half mouthful of water inlet and the water pipe section right side and adjacent water fender are vertically tightly connected, to ensure sewage energy in water pipe section and can only all be flowed out by bend pipe.Bend pipe downwardly extends and bending is arranged the most to the left, and therefore its outlet is towards left setting, namely arranges below water fender, when therefore sewage flows out, is flowed to below water fender by bend pipe.Bend pipe outlet top (also may be installed the water fender linking edge closed on) is provided with elastic film by tightening part, and the shape of elastic film is consistent with bend pipe outlet shape.Under elastic film gravity and natural resiliency effect, elastic film with bend pipe outlet snug fit, thus will realize the effect of outside in fastening sealing bend pipe outlet.And when sewage flows down from water pipe section, to wash elastic film open inside-out and automatically raise elastic film, after sewage stream is complete, sewage stamping press disappears, elastic film then returns to compress the sealing state of bend pipe outlet under natural resiliency effect, it is achieved that be automatically switched off.In this utility model, the outlet end face of bend pipe is obliquely installed, and concrete incline direction is that lower end opposite upper is tilted to the left setting, namely the outlet end face upper end of bend pipe is tilted to the right and arranges lower end and be tilted to the left setting.The purpose being obliquely installed, is to make elastic film elastic under natural resiliency and gravity dual function to buckle at bend pipe outlet, significantly ensure that the seal closing bend pipe outlet, namely ensure that odor-resistant result.This utility model is to utilize the elastic buckles locking structure of elastic film and bend pipe to realize whole channel seal, is not affected, under anhydrous conditions by whether there is water or not, it is ensured that the long term seal of whole path, deodorant；Actual sewage cross-sectional flow area of the present utility model is about the half of whole water pipe section inner chamber, therefore can ensure that the drainage rate of sewage；Additionally, in whole sewage flow path of the present utility model, do not have any can be with the outthrust of hook hair, water fender edge, linking edge and bend loss both ends are all round and smooth settings, the most in use do not have the drawback hooking hair, after life-time service would not occurring, cause the poorly sealed problem even blocked because of hook hair yet.

In the floor drain deodorant non-return its components that this closure is tight, elastic film is structurally made up of two parts, i.e. goes up slice and bottom sheet, and upper slice bottom is corresponding with bottom sheet top links together, and is integrally formed structure.Both differences are not only upper-lower position, and it is relatively thin that the thickness also resided in slice is arranged, and it is thicker that the thickness of bottom sheet is arranged.The purpose so arranged, be make thicker bottom sheet weight much larger than relatively thin upper slice weight, even if the decentralization of the most whole elastic film.Elastic film decentralization has multiple advantageous effect, can be obviously improved the multinomial technical specification of this patent.Being operationally top due to elastic film fixes that locking is motionless and process that in the middle part of elastic film and bottom swings up and down centered by elastic film top around elastic film top with bend pipe or water fender, therefore, after elastic film center moves down, can follow in time and flow out bend pipe current size and the change of liquid level height and swing up and down.Particularly at current by when diminishing suddenly greatly, elastic film must be followed the decline of current liquid level in time and reduce, the most just it is avoided that and leaks the situation that inner core (oscillating deck generally swung up and down) causes oscillating deck to separate with current liquid level because of current sudden change traditionally, namely fundamentally solve tradition floor drain inner core poorly sealed problem causing emitting on foul smell in sewer pipe when draining.The two of the effect of elastic film decentralization are, because upper slice relatively thin therefore going up slice is readily bent, during accordingly even when there are less current, current also can promote full wafer elastic clip to put away bend pipe outlet, serve water just row, the effect of anhydrous closing, fundamentally solve tradition floor drain inner core, the drawback that the floor drain inner core in particular with magnetic-adsorption sealing means cannot be opened under weep impacts and cause sewage to discharge.Being bottom sheet by the three of the effect of elastic clip decentralization maximum with the thrust of bend pipe outlet, the air-flow produced because of other user's drainings in downcomer when so can effectively be buffered in not draining is to bottom sheet impact upwards.As long as bottom sheet and bend pipe outlet closely cooperate, upper slice would not be affected by said flow.Therefore decentralization can strengthen the ability of the anti-flow perturbation of this patent, namely ensure that the sealing reliability of elastic film and bend pipe outlet, effectively prevents from emitting on foul smell.In this patent, although upper slice and bottom sheet variable thickness, but upper slice be the flat limit that closely fasten corresponding with outlet with the medial surface periphery of bottom sheet, the purpose so arranged is ensuring that each portion of elastic film can closely be adjacent in portion each with bend pipe outlet simultaneously when not draining, thus reaches to seal the purpose coordinated.

In this patent, although elastic film top is that the water fender tightened in bend pipe outlet top or correspondence by tightening part is connected edge in version, but, because inside elastic film upper end under the support tightening part with outlet top or be connected with corresponding water fender edge elastic compression coordinate, so elastic film upper end in its natural state time with outlet top or be connected what edge made to be fixed together with corresponding water fender, and be that elastic packing coordinates, so arrange and there is multiple advantageous effect.One of advantageous effect is to ensure that elastic film upper edge is connected the sealing of edge with outlet top or with corresponding water fender, emits problem when being prevented effectively from closed mode on foul smell.The two of advantageous effect are when producing this patent, can produce elastic film according to actual needs and buckle, from outlet, the product that degree is different.Known, all other users can be produced negative pressure during building sewer draining, story height is different, and during other layer of user's sewage effluent, suction force size reverse to this elastic film is also different.It is said that in general, floor is the highest, this suction force is the biggest, and the impact on elastic film is the biggest.Therefore, by setting tighten part to elastic film different tighten degree, can make elastic film to outlet apply different sealing power, the most just can tackle the demand of differing heights floor user, effectively prevent the foul smell and noise produced because of negative pressure-pumping.

As a kind of implementation, described tighten that part includes being installed in bend pipe outlet top two avris tighten brace, tighten brace be provided with tighten support hole, two tighten support hole in be fitted with and tighten support axle, also include being installed in edge on elastic film tightens pushing out ring, tighten pushing out ring and tighten support axle sleeve assembling conjunction, also include with tighten that support hole plug-in mounting coordinates tighten the collar, tighten to be equipped with on collar periphery and tighten external tooth, tighten be evenly equipped with on support hole inwall that plug-in mounting corresponding with tightening external tooth coordinate tighten water jacket, tighten to be evenly equipped with on collar inwall and tighten inside groove, tighten support axle on be equipped with plug-in mounting corresponding with tightening inside groove coordinate tighten internal tooth, tighten be evenly equipped with on pushing out ring inwall plug-in mounting corresponding with tightening internal tooth coordinate tighten glue groove.

Originally tighten part and mainly include being installed in tightening brace, being installed in tightening pushing out ring, being arranged on and tighten pushing out ring and tighten and tighten support axle between brace of elastic film top of outlet two avris, and be arranged on and tighten support hole and tighten and tighten the collar between support axle.Wherein, the quantity tightening brace is two, is separately positioned on the left and right sides, bend pipe outlet top.Tightening brace to be provided with and tighten support hole, tighten support hole and tighten support shaft end suit and coordinates, such elastic film just can support hole by tightening support axle swing up and down with tightening.Tightening the collar is the core component originally tightening part, and its primary structure includes that the body of cirque structure, uniform ring are located at the external tooth that tightens tightening collar periphery, and uniform ring be located at tighten collar inwall tighten inside groove.Tighten be evenly equipped with on support hole inwall that plug-in mounting corresponding with tightening external tooth coordinate tighten water jacket, therefore when tighten the collar insert tighten support hole time, tighten external tooth and be also inserted simultaneously into the tightening in water jacket of correspondence.Owing to tightening external tooth and tightening the snap fit effect of water jacket, tighten the collar and once insert and tighten support hole and cannot circumferentially rotate, serve the effect that circumference is spacing.Same, tighten be equipped with on support axle that plug-in mounting corresponding with tightening inside groove coordinate tighten internal tooth, therefore when tighten support axle insert tighten the collar time, tighten internal tooth and be also inserted simultaneously into the tightening in inside groove of correspondence.Owing to tightening internal tooth and tightening the snap fit effect of inside groove, tighten support axle and once insert and tighten the collar and cannot circumferentially rotate, serve the effect that circumference is spacing.In sum, when tightening the collar and being not inserted into tightening support hole, insert tighten support hole tighten support axle can be freely rotatable, being now sleeved on the elastic film tightened on support axle can also freely swing.And when tighten the collar insert tighten support hole and tighten support axle between time, namely when tighten support axle, tighten the collar with tighten support hole corresponding plug-in time, tighten support axle, tighten the collar and tighten support hole will constitute circumferential spacing matching relationship.Due to tighten support axle, tighten the collar and tighten support hole be all interference fit, therefore three is equivalent to, when being inserted to together, the structure that is integrally fixed, can not circumference movement can not circumferentially rotate.Therefore, when assembling originally tightens part, first turn an angle with the pushing out ring that tightens that suit is tightened support axle, the convergence part tightening pushing out ring and elastic film is made to produce elastic deformation, and the elasticity utilizing this elastic deformation to produce makes elastic film tightly be fastened on bend pipe outlet, finally it is inserted to tighten support hole and tightening completes tightening the collar the location tightening support axle between support axle.Now, tighten pushing out ring by tightening support axle and keep twisted posture, and tighten edge on pushing out ring and elastic film and also keep elastic compression with the corresponding linking edge of edge on outlet or water fender.In order to avoid tightening support axle and tightening pushing out ring and skid, corresponding with tightening internal tooth tighten glue groove tightening to be equipped with on pushing out ring inwall, substantially increase the reliability originally tightened when part tightens.

As improvement, described in tighten external tooth and to tighten the plug-in mounting end of internal tooth be tapering, described in tighten collar face and be coated with glue.

External tooth will be tightened and to tighten the plug-in mounting end of internal tooth be tapering, when tightening the collar and be inserted to tighten support hole and tighten between support axle without alignment angle, only need to suitably rotate and tighten the collar and can make to tighten water jacket and tighten inside groove and be directed at tapering simultaneously, operate the simplest.Tightening collar face spreading glue, can make to tighten support axle, tighten the collar and tighten that support hole is fixing to be pasted together, it is ensured that functional reliability.

As improvement, the following inwall of bend pipe outlet is provided with the U-lag that track takes the shape of the letter U, and U-lag cell wall constitutes wedge-shaped part with outlet inwall, and wedge-shaped part edge corresponding with elastic film buckles and coordinate.

Because edge is in downwardly projecting arc under bend pipe outlet, after therefore a groove being set on the following inwall of bend pipe outlet, i.e. constitute the U-lag that track takes the shape of the letter U.This U-lag is consistent with elastic film shape and U-lag cell wall constitutes wedge-shaped part with outlet inwall, wedge-shaped part edge corresponding with elastic film buckles and coordinates, so setting not only can guarantee that the friction tight sealing of button, the problem blown afloat by elastic film when preventing air blow back can also be played, namely ensure that round-the-clock sealing of the present utility model.

As improving further, the outlet top of described bend pipe is the flat side corresponding with water fender, and outlet is downwardly projecting arc limit below.

On outlet, edge is arranged to horizontal-extending flat side and elastic film can be made to be free to burnishing surface swing up and down or folding, and particularly when fastening on outlet, smooth elastic film can ensure that the tightness of fastening.Outlet is that downwardly projecting arc limit is arranged below, elastic film periphery not only can be made uniformly to fasten with outlet to ensure tightness, it is also possible to enable flowing water smooth outflow in round and smooth bend inner chamber.

As improvement, the vertical section of described elastic film is the wedge shape that narrower lower end, upper end is wider, and the bottom sheet of described elastic film is internal or outside is provided with counterweight.

It is up-narrow and down-wide wedge shape that elastic film is designed to midship section, not only conform to a construction features that relatively thin bottom sheet is thicker, make elastic film decentralization, and make elastic film two sides all in plane, both ensure that to coordinate with the sealing of bend pipe outlet and also make overall appearance more attractive in appearance.Counterweight is set inside the bottom sheet of elastic film or counterweight is set outside elastic film bottom sheet, elastic film and counterweight decentralization can be made as far as possible under reducing elastic film volume premise.It should be strongly noted that elastic film intermediate plate volume is excessive, when current are bigger, the lower sector-meeting started touches sewer pipe inwall, affects the opening degree of elastic film.Therefore, after arranging counterweight, when can make mass-flow, elastic film starts get Geng Gao, is conducive to accelerating draining.

As improving further, the end face top of described inserting column end is installed with the spherical crown that sphere is arranged upward, spherical crown lower surface is installed with not only to the arc spring lamination extended away from spherical crown direction but also extend to inserting column, and arc spring lamination end extends the periphery trajectory of inserting column.
