In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1 and 2, in one embodiment, a drain system 10 for draining a plumbing fixture is provided, including a drain line 100, a drain leg 200, and a drain leg 300. One end of the branch drain pipe 200 communicates with the drain line 100, and the other end of the branch drain pipe 200 is used for communication with a sanitary fixture. One end of the exhaust branch pipe 300 is communicated with the drain line 100, and the other end of the exhaust branch pipe 300 is used for communication with a sanitary ware.

In the drainage system 10 of the above embodiment, when the sanitary ware needs to discharge sewage, the sewage of the sanitary ware is discharged into the drainage pipeline 100 through the drainage branch pipe 200, so that the sewage can be discharged into the municipal drainage pipe network through the drainage pipeline 100. In the process of discharging sewage, air in the drainage branch pipe 200 and the drainage pipeline 100 can be discharged through the exhaust branch pipe 300, so that air lock in the drainage system 10 is avoided, the influence on the discharge of sewage is avoided, and the drainage smoothness and reliability of the drainage system 10 are improved. In addition, since the exhaust branch pipe 300 also communicates the sanitary ware with the drain line 100, the exhaust branch pipe 300 can discharge sewage even when the drain branch pipe 200 is blocked, so as to prevent the sanitary ware from having a sewage back-flush phenomenon. Meanwhile, when the instantaneous flow of the sewage in the drainage pipeline 100 is large and the sanitary ware needs to discharge the sewage, part of the sewage discharged by the sanitary ware can be temporarily discharged into the exhaust branch pipe 300, so that the time for the sewage to enter the drainage pipeline 100 is prolonged, the instantaneous large flow of the drainage pipeline 100 is avoided, the sewage in the sanitary ware can be timely discharged, and the drainage of the drainage system 10 is smooth. Compared with the traditional drainage system 10, the drainage branch pipe 200 is communicated with the drainage pipeline 100, the length of the drainage branch pipe 200 is reduced, and the cost of the drainage system 10 is reduced. Moreover, when the branch drain pipe 200 is unobstructed, the branch exhaust pipe 300 discharges air in the branch drain pipe 200 and the exhaust pipeline, so as to ensure smooth discharge of sewage by the drainage system 10; when the drain branch pipe 200 is clogged, the exhaust branch pipe 300 can function as the drain branch pipe 200 to prevent back-flushing of sewage from the plumbing fixture.

Wherein, the sanitary ware can be a toilet, a hand washing sink, a floor drain and other devices needing sewage discharge.

As shown in fig. 1 and 2, the drain line 100 further includes a vertical drain stand pipe 110, and one end of the drain branch pipe 200 and one end of the gas discharge branch pipe 300 are both communicated with the drain stand pipe 110. Thus, when sewage enters the vertical drainage pipe 110, the sewage can flow rapidly under the action of gravity, so as to avoid solid matters in the sewage from blocking the drainage system 10, and improve the drainage smoothness and reliability of the drainage system 10.

Alternatively, one end of the drain branch pipe 200 is disposed at a position below 1000mm from the top of the drain stand pipe 110; one end of the exhaust branch pipe 300 is disposed at a position 600mm or less from the top of the drainage standpipe 110. Thus, the smoothness and reliability of the drainage system 10 are improved.

Wherein, the distance between one end of the branch drain pipe 200 and the top of the vertical drain pipe 110 can be flexibly adjusted according to the actual use requirement. For example, one end of the drain branch pipe 200 is disposed 1000mm, 1100mm, 1200mm, or the like from the top of the drain stand pipe 110.

Wherein, the distance between one end of the exhaust branch pipe 300 and the top of the drainage stand pipe 110 can be flexibly adjusted according to the actual use requirement. For example, one end of the exhaust branch pipe 300 is disposed 600mm, 700mm, 800mm, or the like from the top of the drainage stand pipe 110.

As shown in fig. 2, alternatively, one end of the exhaust branch pipe 300 is disposed above one end of the drain branch pipe 200 in the vertical direction. Thus, the air discharged from the branch drain pipes 200 can flow upward along the axial direction of the vertical drain pipe 110 and be discharged from the branch vent pipes 300, and the sewage discharged from the branch drain pipes 200 can flow downward along the axial direction of the vertical drain pipe 110 under the action of gravity and be discharged to a municipal drainage network, thereby preventing the air and the sewage from interfering in the drainage pipeline 100 and improving the smoothness and reliability of the drainage system 10.

As shown in fig. 2, the drain line 100 may further include a horizontal drain cross pipe 120 extending horizontally, and the horizontal drain cross pipe 120 may be in communication with the vertical drain pipe 110 to form a drain passage. In this way, the drain line 100 can be flexibly adjusted according to the actual use requirements, and the applicability of the drain system 10 is improved.

In other embodiments, one end of the branch drain pipe 200 and one end of the branch exhaust pipe 300 can also communicate with the horizontal drain pipe 120, and the principle is similar and will not be described herein.

In this way, the sanitary ware is communicated with the drain branch pipe 200 and the exhaust branch pipe 300 through the switching pipe 400, and convenience in installation of the drain pipe 100 and the sanitary ware is improved.

Wherein the venting end 420 is disposed below the plumbing fixture in a vertical orientation. Thus, when the drain branch pipe 200 is clogged, the sewage of the sanitary ware can be allowed to flow into the exhaust branch pipe 300 through the exhaust end 420.

When the water inlet end 430 of the switching pipe 400 is blocked to the water outlet end 410, or the water outlet branch pipe 200 is blocked, the sewage of the sanitary ware can pass through the switching pipe 400 between the water inlet end 430 and the water outlet end 420 and the water outlet branch pipe 300, and the sewage is discharged to the water outlet pipeline 100, so as to prevent the sanitary ware from sewage backflushing.

Further, the axis of the transition pipe 400 is disposed obliquely with respect to the horizontal plane, and the exhaust end 420 is disposed above the drain end 410 in the vertical direction. Thus, when the drainage system 10 operates normally, the sewage of the sanitary ware can all flow into the drainage branch pipe 200 through the switching pipe 400 between the water inlet end 430 and the drainage end 410, so that the smoothness of the exhaust branch pipe 300 is ensured, and the reliability and the stability of the drainage system 10 are improved.

Wherein, the inclination angle of the axis of the converting pipe 400 relative to the horizontal plane can be flexibly adjusted according to the actual use requirement.

As shown in fig. 1 and 2, in one embodiment, the axis of the water inlet end 430 is disposed at an obtuse angle with respect to the axis of the water outlet end 410. Thus, when the waste water of the sanitary ware flows into the switching pipe 400 through the water inlet end 430, the waste water maintains a minute velocity in a direction close to the water outlet end 410, so that the waste water can smoothly and rapidly flow into the water outlet branch pipe 200, and the smoothness and reliability of the water discharge system 10 are improved.

Wherein, the angle between the axis of the water inlet end 430 and the axis of the water outlet end 410 can be flexibly adjusted according to the actual use requirement. For example, the angle between the axis of the water inlet end 430 and the axis of the water outlet end 410 may be 120 °, 145 °, 150 °, or the like

As shown in fig. 2, the drain system 10 optionally further includes a connection pipe 500 for communicating the water inlet end 430 with the plumbing fixture. In this manner, the ease and adaptability of assembly between the drain system 10 and the plumbing fixture is improved.
