Description

Domestic sewage discharging device for preventing water and gas from returning

Technical Field

The utility model belongs to the field of life specifically is a domestic sewage discharging equipment who prevents water and gas return.

Background

In actual life, in the drainage pipeline of kitchen or bathroom, blocking phenomenon often appears, because rivers can't circulate, cause among the domestic drainage pipeline, the phenomenon of running back appears.

At present, a kitchen or a toilet usually adopts a one-way valve to solve the problem of water return, but the one-way valve can only be transversely installed but can not be vertically installed, and has poor tightness and unstable performance, when the water pressure of water return is too high, the one-way valve is difficult to continue to be stably used, and the odor in a sewage discharge pipeline is difficult to be well isolated in the normal use process;

this application has established can waterproof gas proof waste fitting discharging through the transformation to the one-way check valve of running water. According to the principle of the application, other products such as floor drains and the like can be manufactured.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved is as follows:

the utility model provides a domestic waste fitting discharging who prevents water and gas return has solved the problem that mentions in the background art to the not enough of prior art.

The technical scheme is as follows:

in order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

a domestic sewage device for preventing water and gas from returning comprises:

the bottom of the drain pipe is provided with a sealing cover for plugging a lower pipe orifice of the drain pipe through a rebound mechanism, and one side of the sealing cover is rotatably connected with the drain pipe through a rotating shaft;

the rebounding mechanism comprises two hanging lugs and a tension spring, wherein one hanging lug is fixed at the top of the sealing cover, the other hanging lug is fixed on the inner wall of the drainage pipe, and the tension spring is detachably hung between the two hanging lugs.

In a possible implementation, a sealing surface is provided between the bottom of the drain pipe and the sealing cover.

In a possible implementation, the sealing surface may be the sealing cover and the drain pipe, or may be an additional sealing gasket.

In a possible implementation manner, the resilient mechanism may also be an elastic band, one end of the elastic band is connected with the inner wall of the drain pipe, and the other end of the elastic band is connected with the sealing cover.

In a possible implementation manner, the resilience mechanism comprises a torsion spring, the torsion spring is mounted on a rotating shaft between the sealing cover and the drain pipe, and the torsion spring is used for upwards rotating the sealing cover to enable the sealing cover to be in contact with and extruded by the drain pipe.

Has the beneficial effects that:

because the sealing cover can rotate downwards, under the action of matching with the rebound mechanism, the sealing cover can prevent sewage and odor in the lower pipe body from entering the drain pipe while not obstructing drainage;

when the inside sewage of body rises down, sewage can upwards extrude sealed lid, and is same, and rivers are the bigger to sealed lid extruded pressure, and then sealed lid and sealed face's extrusion pressure is bigger, is difficult to make rivers get into in the drain pipe more.

Detailed Description

The embodiment of the application solves the problems in the prior art by providing the household sewage discharge device for preventing reverse water and reverse air.

In order to solve the above problems, the technical solution in the embodiment of the present application has the following general idea:

example 1:

the specific structure of this embodiment, as shown in fig. 1, is a domestic anti-reverse-water and anti-reverse-air pollution discharge apparatus, including:

the water draining pipe 3 is characterized in that the bottom of the water draining pipe 3 is provided with a sealing cover 2 for plugging the lower pipe orifice of the water draining pipe 3 through a rebounding mechanism, and one side of the sealing cover 2 is rotatably connected with the water draining pipe 3 through a rotating shaft 6;

the rebounding mechanism comprises two hanging lugs 5 and a tension spring 4, wherein one hanging lug 5 is fixed on the top of the sealing cover 2, the other hanging lug 5 is fixed on the inner wall of the water discharging pipe 3, and the tension spring 4 is detachably hung between the two hanging lugs 5.

In some examples, a sealing surface 1 is provided between the bottom of the drain pipe 3 and the sealing cover 2, and the sealing surface 1 may be the sealing cover 2 and the drain pipe 3, or may be an additional sealing gasket.

By adopting the technical scheme:

when in use, the drain pipe 3 is arranged in a drainage channel of a kitchen sink or a drainage channel of a toilet;

when the drain pipe 3 drains water downwards, water flow can impact the sealing cover 2, so that the sealing cover 2 rotates downwards around the rotating shaft 6 to discharge sewage, at the moment, the tension spring 4 is in a stretching state, after the sewage stops being discharged from the drain pipe 3, the tension spring 4 can reset to enable the sealing cover 2 to rotate to an initial position, and under the action of the sealing surface 1, the sealing cover 2 can be tightly pressed against the sealing surface 1, so that gas and sewage below the drain pipe 3 are prevented from entering;

in addition, when the water level inside the lower pipe body 1 rises, the sealing cover 2 is also pressed upwards by the water flow inside the lower pipe body 1, and similarly, the larger the pressure of the water flow on the sealing cover 2 is, the larger the pressing pressure of the sealing cover 2 and the sealing surface 1 is, the more difficult the water flow enters the drain pipe 3;

because the tension spring 4 tends to tighten, the whole device can be transversely or longitudinally or obliquely arranged in the drainage pipeline, and the installation angle is diversified.

Example 2:

in the specific structure of this embodiment, as shown in fig. 1, the resilient mechanism may also be a torsion spring, the torsion spring is mounted on the rotating shaft 6 between the sealing cover and the drain pipe, and the torsion spring is used to rotate the sealing cover upwards to press the sealing cover in contact with the drain pipe.

By adopting the technical scheme:

utilize the torsional spring to play the inside cavity that the drain pipe 3 was occupied to springback mechanism when reseing to sealed lid 2 to prevent to obstruct debris and pass drain pipe 3, and then avoid debris to pile up in drain pipe 3 is inside.

Example 3:

in the specific structure of this embodiment, as shown in fig. 1, the tension spring can be replaced by an elastic band.

By adopting the technical scheme:

the elastic band can be made of corrosion-resistant colloid materials or nylon materials, such as silica gel, and the surface of the elastic band is smooth, so that the phenomenon that the rebound mechanism is corroded is avoided, and the service life of the rebound mechanism is prolonged.

Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications are intended to be within the scope of the present invention.
