nullAs improvement，Described water pipe section infraoral includes Zuo Bankou and You Bankou，Left half mouthful of upper sealing is installed with water fender，It is connected with one section of bend pipe downwardly extended and bend to the left on right half mouthful，The sealing corresponding with half mouthful of the right side and water fender linking edge of the water inlet of bend pipe is affixed，The outlet of bend pipe is that lower end opposite upper is tilted to the left setting towards left setting and outlet end face，Described automatic plugging apparatus is included being movably hinged by articulated elements and is arranged on bend pipe outlet top or the water fender that is adjacent to bend pipe outlet top is connected the elastic film of buckle closure bend pipe outlet in edge，It is provided with free gap with being connected between edge with corresponding water fender inside between outlet top or elastic film upper end inside elastic film upper end，Free gap puts away the distance increase of outlet with elastic film and increases，And elastic film is airtight fasten to outlet time disappear，Elastic film include being docking together relatively thin upper slice and thicker bottom sheet，Upper slice be the flat limit that closely fasten corresponding with outlet with the medial surface periphery of bottom sheet.

For convenience of narration, 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 articulated elements, 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 this floor drain deodorant non-return its components the most easy to maintenance, 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, elastic film top is the water fender linking edge being movably articulated in bend pipe outlet top or correspondence by articulated elements, and therefore, whole elastic film can be freely swung above bend pipe outlet by articulated elements.It is to say, when sewage effluent, the deadweight overcoming elastic film is promoted elastic film to be swung up by dirty sewage impulse force, and bend pipe outlet is opened, sewage is free, smooth and easy discharge.When sewage discharging is complete, elastic film is swung downward under self gravitation effect, until swinging to bend pipe outlet, outlet is closed, and the foul smell in downcomer can not up emit.In this patent, being provided with a free gap with being connected between edge with corresponding water fender inside between outlet top or elastic film upper end inside elastic film upper end, the size of this free gap is changed by the swing position that articulated elements swings with elastic film and changes.When not having sewage discharging, elastic film is adjacent to bend pipe outlet, and free gap is zero, namely disappears, and now bend pipe outlet is blocked by elastic film completely, and this patent is closed.When there being sewage discharge, dirty sewage promotes elastic film to put away outlet by articulated elements, and now free gap is become big by zero, is had by without becoming.Now, free gap has multiple effect, and effect one is to make elastic film upper end and bend pipe outlet top or frictional force disappearance be connected between edge with corresponding water fender, namely contributes to current and wash elastic film open, reaches the purpose of draining as early as possible.The two of effect are to increase the second channel between bend pipe outlet and sewer, increase sewage discharge speed.Along with the increase of sewage current, the distance that elastic film is started is the biggest, and free gap is the biggest.

As a kind of implementation, described articulated elements includes the hinged brace being installed in bend pipe outlet top two avris, hinged brace is provided with hinged support hole, in two hinged support holes, activity is fitted with hinged support axle, also include being installed in the hinged pushing out ring of edge on elastic film, hinged pushing out ring closes with the assembling of hinged support axle sleeve, the diameter in hinged support hole is more than the diameter of hinged support axle, hinged support hole has one makes hinged support wheelbase separate out the near position point that the mouth of a river is closest, when hinged support axle is positioned at this near position point, elastic film top and hinged pushing out ring are crossed free gap and corresponding outlet top or are connected edge compression fit with corresponding water fender.

This articulated elements mainly includes being installed in the hinged brace of outlet two avris, the hinged pushing out ring being installed in elastic film top and the hinged support axle being arranged between hinged pushing out ring and hinged brace.Wherein, the quantity of hinged brace is two, is separately positioned on the left and right sides, bend pipe outlet top.Hinged brace is provided with hinged support hole, and hinged support hole coordinates with hinged support shaft end suit, and such elastic film just freely up and down can be swung by hinged support axle and hinged support hole.In this patent, the diameter in hinged support hole is greater than the diameter of hinged support axle or is more than the diameter of hinged support shaft end.So arranging and mainly have two purposes, one is to expand hinged support axle range of activity in hinged support hole, and the swing making elastic film is freer.Another purpose is contemplated to avoid make hinged support axle rotate in hinged support hole not freely because the dirt in sewage conceals hinged support hole, so that there is bite phenomenon when relative bend pipe outlet swings in elastic film, and then the poorly sealed problem that can not fully open impeded drainage when emitting foul smell and draining when causing not draining.In this patent, hinged support hole has one and makes hinged support wheelbase separate out the near position point that the mouth of a river is closest.When hinged support axle is positioned at this near position point, on elastic film, edge and hinged pushing out ring are crossed free gap and corresponding outlet top or are connected edge compression fit with corresponding water fender.Therefore, time in off position, if hinged support axle is positioned near position point the most simultaneously, then the most whole elastic film, by being closely fastened on bend pipe outlet, thus serves the effect fully sealing bend pipe outlet, stopped the probability emitted on foul smell.

In order to achieve the above object, bottom, hinged support hole is installed with hinged bracer, and it is upper end away from elastic film lower end near the hinged hypotenuse of elastic film that hinged bracer presses close to the edge in hinged support hole, and hinged hypotenuse makes hinged support axle slide near position point.

In this hinged bracer, the hinged bracer edge pressing close to hinged support hole is a hinged hypotenuse, this hinged hypotenuse upper end arranges lower end away from elastic film and arranges near elastic film, therefore, hinged hypotenuse and hinged support hole inwall constitute wedge-shaped opening structure or the bell-mouth structure of air of width under a upper end width.The Main Function of wedge-shaped opening structure is exactly that hinged support axle is carried out spacing by the edge utilizing hinged hypotenuse to tilt, on the premise of elastic film is not affected by other external force, namely when not draining, time the most in off position, hinged support axle is made to slide to downwards near position point along hinged hypotenuse under self gravitation and elastic film action of gravity.So, it is achieved that above-mentioned purpose, namely time in off position, hinged support axle is positioned near position point, the most whole elastic film, by being closely fastened on bend pipe outlet, serves the effect fully sealing bend pipe outlet, has stopped the probability emitted on foul smell.Contrary, when draining, namely when opening, impact along with current, elastic film drives hinged support axle to move up in hinged support hole, owing to hinged hypotenuse and the hinged support hole inwall of hinged bracer constitute the wedge-shaped opening structure of width under a upper end width, the range of activity of the most hinged support axle suddenly increases, and elastic gum sector-meeting completes a displacement-type in the hinged support hole that diameter is bigger by hinged support axle and swings.Now, not only can produce free gap, and hinged support hole circular arc interior wall construction can make the displacement-type of hinged support axle and elastic film swing more nature with smooth and easy.

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.

In sum, use the floor drain deodorant non-return its components easy to maintenance of this structure, rational in infrastructure, assemble quick, convenient disassembly, odor-resistant result is good, deodorant time length, drainage speed are fast, and is not affected by anhydrous, will not hook hair, also will not block or cause seal failure because of hook hair, maintenance clean is convenient.

In order to achieve the above object, bottom, hinged support hole is installed with hinged bracer 406, and it is upper end away from elastic film lower end near the hinged hypotenuse 407 of elastic film that hinged bracer presses close to the edge in hinged support hole, and hinged hypotenuse makes hinged support axle slide near position point.In this hinged bracer, the hinged bracer edge pressing close to hinged support hole is a hinged hypotenuse, this hinged hypotenuse upper end arranges lower end away from elastic film and arranges near elastic film, therefore, hinged hypotenuse and hinged support hole inwall constitute wedge-shaped opening structure or the bell-mouth structure of air of width under a upper end width.The Main Function of wedge-shaped opening structure is exactly that hinged support axle is carried out spacing by the edge utilizing hinged hypotenuse to tilt, on the premise of elastic film is not affected by other external force, namely when not draining, time the most in off position, hinged support axle is made to slide to downwards near position point along hinged hypotenuse under self gravitation and elastic film action of gravity.So, it is achieved that above-mentioned purpose, namely time in off position, hinged support axle is positioned near position point, the most whole elastic film, by being closely fastened on bend pipe outlet, serves the effect fully sealing bend pipe outlet, has stopped the probability emitted on foul smell.Contrary, when draining, namely when opening, impact along with current, elastic film drives hinged support axle to move up in hinged support hole, owing to hinged hypotenuse and the hinged support hole inwall of hinged bracer constitute the wedge-shaped opening structure of width under a upper end width, the range of activity of the most hinged support axle suddenly increases, and elastic gum sector-meeting completes a displacement-type in the hinged support hole that diameter is bigger by hinged support axle and swings.Now, not only can produce free gap, and hinged support hole circular arc interior wall construction can make the displacement-type of hinged support axle and elastic film swing more nature with smooth and easy.

When actual production, the following inwall of bend pipe outlet is provided with the U-lag 13 that track takes the shape of the letter U, and U-lag cell wall constitutes wedge-shaped part 14 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.

In the present embodiment, 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.

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.
