The tangential direction of the inner wall of the discharge pipe interface 21 is swirled and discharged.

Specifically, the bottom surface of the second assembly part 2 is inclined, and the waste water discharge pipe interface 21 is connected to the lower end of the bottom surface of the second assembly part 2; The drainage groove at the pipe interface 21.

In this embodiment, the first waste water discharge pipe interface 11 is connected to the upper general drainage pipe for receiving the waste water discharged from the upper layer pipe; the second waste water discharge pipe interface 12 is communicated with the sewage pipe of the toilet floor drain, It is used to receive the waste water produced by the shower or the washbasin; the waste water discharge pipe interface 21 is communicated with the lower general drainage pipeline, and is used to discharge all the collected waste water to the general drainage pipeline. In addition, the first wastewater discharge pipe interface 11 and the wastewater discharge pipe interface 21 are located on the same side and communicate with each other; the second wastewater discharge pipe interface 12 is located on the other side.

Therefore, the cavity is set in a flat shape, thereby reducing the height of the cyclone, so that it can be pre-buried in the floor without reducing the height of the floor. The bottom of the cavity is tilted, so that the waste water flowing into the cavity along the first waste water discharge pipe interface 11 and the second waste water discharge pipe interface 12 flows under the action of its own gravity and is discharged from the waste water discharge pipe interface 21, so as to reduce the temporary retention of waste water. Wastewater in the chamber. At the same time, when the water pressure of the wastewater flowing in along the first wastewater discharge pipe interface 11 is greater than the water pressure of the wastewater flowing in along the second wastewater discharge pipe interface 12, the wastewater can also flow back to the wastewater discharge pipe interface 21 due to the influence of gravity to be discharged. , to avoid the reverse discharge of waste water into the second waste water discharge pipe interface 12 . In addition, by setting the drainage member 3, the waste water can be swirled and discharged along the tangential direction of the inner wall of the waste water discharge pipe interface 21, so as to ensure that when the discharge volume of the waste water in the cyclone is large, it can still be swirled from the waste water discharge pipe interface 21 against the wall.

Specifically, the anti-backflow ball seat 41 is provided on the inner wall of the second assembly part 2 ; the centers of the water inflow hole 13 and the water discharge hole 411 are located on the same axis.

Therefore, the water discharge hole 411 on the anti-backflow ball seat 41 will limit the position of the anti-backflow ball 42 in the horizontal direction. The water discharge holes 411 opened on the overflow seat 41 move in the vertical direction. When there is accumulated water on the floor surface, the accumulated water can enter through the accumulated water inflow hole 13 and flow out from the accumulated water discharge hole 411, and then be discharged into the waste water discharge pipe interface 21; at the same time, when the waste water overflows, the overflow prevention ball 42 Under the buoyancy of the waste water, it tightly fits the water inflow hole 13 and seals the water inflow hole 13 to prevent the overflowing sewage in the waste water discharge pipe interface 21 from overflowing the cyclone.

In addition, during the use of the cyclone of the present invention, the accumulated water on the ground may flow into the cyclone from the gap on the floor, thereby infiltrating from the gap of the lower floor.
