Description

A kind of odor-resistant downcomer pipe

Technical field

The utility model belongs to downcomer field, and in particular to a kind of odor-resistant downcomer pipe.

Background technique

Downcomer is used to the pipeline of connection outlet device (such as washbasin, laundry tray) and surface duct, it plays certain Prevent from returning the effect of taste.Traditional downcomer is using S-type curved or built-in sealing structure for water to reach odor-resistant result, both knots The shortcomings that structure is: stink can be returned up directly when anhydrous, although can completely cut off the stink in pipeline, water seal when draining Itself be to be formed by dirty water, the time has been grown can be directly smelly, so can only short-term deodorization can not permanently effective deodorization.

Existing Chinese patent document 201220175839.5 discloses a kind of odor-resistant downcomer pipe, main technical schemes are as follows: A kind of odor-resistant downcomer pipe, including downcomer are provided with the connector for being separately connected outlet device and surface duct, institute at downcomer both ends It states and is provided with check valve on downcomer, which includes the installation sleeve being connected to the downcomer and be detachably secured to pacify Spool in sleeved is provided with water inlet, water outlet and shaped form runner on spool, and the shaped form runner is by water flow by erecting Direct current is hingedly equipped with a closure door to horizontal flow direction is transformed into, in spool water outlet, and the closure door utilizes self gravity when anhydrous Automatic sealing is on the water outlet of spool and is closed, and the closure door is jacked up by water flow when draining, water outlet of the water flow from spool Outflow.Due to, without sealing structure, being influenced not using easy over time by hair etc. between the closure door and downcomer of its check valve It can be closed completely, cause still to have foul smell and float upwards from downcomer, its odor-resistant result is made to have a greatly reduced quality.

Utility model content

The purpose of this utility model is to solve the above problems, and provides a kind of better tightness, and odor-resistant result is more obviously prevented Smelly downcomer.

To achieve the above object, the utility model provides the following technical solutions:

A kind of odor-resistant downcomer pipe, including downcomer are separately connected outlet device and surface duct interface, ground line at its both ends The sealing ring for preventing water flow from overflowing is set on the outer wall of pipeline joint, surface duct interface upper end is equipped with capping, under described Check valve is equipped between water pipe and outlet device, the check valve is polygon, and smelly core of inside setting up defences, the deodorization core includes vertical Pipe and curved pipe；The curved pipe exit end face is equipped with arc convex, and outlet is externally provided with baffle, and the baffle goes out close to curved pipe The edge of mouth side is equipped with arc groove, and the arc convex matches with arc groove size；The baffle other side is equipped with Pillar, the baffle are connected in vertical pipe by shaft.

Further, the arc convex and arc groove collectively form water outlet sealing structure.

Preferably, the check valve is taper, top cross section is greater than lower cross section.

Preferably, the downcomer is scalable water pipe.

The utility model has the beneficial effects that:

The utility model is by being respectively set arc convex and arc on check valve water outlet on downcomer and baffle Groove, the pillar on the one hand can anti-baffle plate be bonded with the end face of upper part, cannot fall, on the other hand can increase naturally Add the self weight of baffle, so that its gravity during downward closure is bigger, the arc of arc groove and curved pipe exit end face Shape protrusion closure is even closer, improves leakproofness of the downcomer under no flowing water state, further improves and be lauched bottom of the tube The problem of back foul taste, while the utility model also has structure simple, manufacturing cost is low, and odor-resistant result is significant, should not be by hair Blocking, dismounting and advantage easy to maintenance.

Detailed description of the invention

In order to illustrate more clearly of the utility model embodiment technical solution, will make below to required in embodiment description Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model in order to more clearly Illustrate the utility model embodiment or technical solution in the prior art, for those of ordinary skill in the art, is not paying Out under the premise of creative work, it is also possible to obtain other drawings based on these drawings.

Specific embodiment

A kind of odor-resistant downcomer pipe as shown in Figs. 1-2, including downcomer 3 are separately connected outlet device 1 and ground at its both ends Facial canal pipeline joint 6 is set with the sealing ring 5 for preventing water flow from overflowing, the surface duct interface on the outer wall of surface duct interface 6 6 upper ends are equipped with capping 4, and check valve 2 is equipped between the downcomer 3 and outlet device 1, and the check valve 2 is polygon, in It sets up defences smelly core 20, the deodorization core 20 includes vertical pipe 21 and curved pipe 22；It is convex that 22 exit end face of curved pipe is equipped with arc 23 are played, outlet is externally provided with baffle 24, and the baffle 24 is equipped with arc groove 25 close to the edge of curved pipe 22 outlet side, described Arc convex 23 matches with 25 size of arc groove；24 other side of baffle is equipped with pillar 26, and the baffle 24 is by turning Axis 27 is connected in vertical pipe 21.

Further, the arc convex 23 collectively forms water outlet sealing structure with arc groove 25.

Preferably, the check valve 2 is taper, top cross section is greater than lower cross section, increases the pressure of water, more It is flowed out conducive to the water on top.

Preferably, the downcomer 3 be scalable water pipe, can length according to actual needs stretch.

26 one side of pillar can anti-baffle plate 24 be bonded with the end face of upper part, cannot fall naturally, another party Face can increase the self weight of baffle 24, so that its gravity during downward closure is bigger, arc groove 25 and curved pipe The arc convex 23 of 22 exit end faces is closed even closer.

The working process of the utility model is as follows:

Such as Fig. 3, when water flow 7 is flowed down from outlet device 1, because of the impact force of water flow 7, baffle 24 can be rushed, so that water Stream 7 passes through；Such as Fig. 4, in the case where non-water flow 7 passes through, baffle 24 is closed downwards by gravity, arc groove 25 and song The arc convex 23 of 22 exit end face of type pipe is in tight closure state, can be by baffle 4 when there is gas 8 to return from downcomer 3 It blocks, it can not be in intake chamber, so that foul smell be effectively prevent to return taste.Meanwhile water outlet in tight closure state but also its It is not easy to be blocked or tangled by hair class dirt, ensure that the leakproofness of water outlet.

The utility model is by being respectively set arc convex 23 on 2 water outlet of check valve on downcomer 3 and baffle 24 With arc groove 25, leakproofness of the downcomer 3 under no flowing water state is improved, further improves 3 bottom back foul of downcomer The problem of, while the utility model also has structure simple, manufacturing cost is low, and odor-resistant result is significant, should not be torn open by hair obstruction Dress and advantage easy to maintenance.

The content not being described in detail in the utility model is the prior art.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
