Description
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.
Fig. 1 is the overall structure diagram of the utility model;
Fig. 2 is the utility model deodorization core overall structure diagram;
Fig. 3 is the utility model deodorization core opening state schematic diagram;
Fig. 4 is the utility model deodorization core closed state schematic diagram.
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.
