As shown in fig. 4, in some embodiments of the present application, a side of the guide groove 222 away from the guide plate 221 is connected to the body portion 210 and is formed with a blocking portion 2221. In this embodiment, the water flowing in from the second water inlet end 120 is guided by the guide plate 221 and then flows into the guide groove 222, and when the water flows through the guide groove 222, since the blocking portion 2221 is disposed at the position where the guide groove 222 is connected to the main body 210, the water flow is blocked by the blocking portion 2221, that is, the water drops first and rises during the flowing process, so that the inertia force of the water flow can be reduced, the speed of the water flow is reduced, the water flow is finally guided to the inclined flow guiding section 223, and finally the water flow is guided to flow by being attached to the inner wall of the main body 210.

Referring to fig. 10, a schematic flow direction of water flowing from the second water inlet end 120 in the drainage device is shown. When the wastewater to be discharged flows to the inclined flow guide section 223 from the guide groove 222, because the water flows through the inclined flow guide section 223 at a certain inclination angle, when the included angle B between the inclined flow guide section 223 and the axis of the main body 210 is designed to be 35 ° to 45 °, the water flows along the inclined angle, so that the water flowing into the main body 210 moves along the spiral moving track.
In some embodiments of the present application, the inclined flow guiding section 223 protrudes from the main body 210, and a maximum dimension of a plane where an axis of the inclined flow guiding section 223 to the second water inlet end 120 is located is 10mm to 15mm larger than a radius of the main body 210.

In some specific embodiments, the cross-sectional area of the angled flow guide section 223 may be greater than 3925mm2This enables the drainage apparatus to have a large drainage capacity.
As shown in fig. 4, in some embodiments of the present application, the drainage device further includes a first guide ring 410, the first guide ring 410 is located inside the main body 210, and the first guide ring 410 is connected to the first water inlet end 110, and an inner diameter D1 of the first guide ring 410 near the first water inlet end 110 is greater than an inner diameter D2 of the first guide ring 410 far from the first water inlet end 110. In this embodiment, the inner diameter D1 of the first guide ring 410 close to the first water inlet end 110 is larger than the inner diameter D2 of the first guide ring 410 away from the first water inlet end 110, so that the water flowing from the first water inlet end 110 can be collected to the middle, the water entering from the first water inlet end 110 and the water entering from the second water inlet end 120 are prevented from colliding when being collected, and the drainage device further has the advantages of low vibration and low noise.

The tapered pipe 300 enables water flowing in from the second water inlet end 120 to closely adhere to the inner wall of the drainage device and flow, thereby preventing water entering from different water inlets from violently colliding to generate vibration and noise, and compared with the drainage pipe without the tapered pipe 300 in the related art, the drainage device in the embodiment can further reduce vibration and noise generated during the use of the pipe.
Referring to fig. 4, in some embodiments of the present application, the drainage device further includes a second deflector ring 420, one end of the second deflector ring 420 is connected to the tapered tube 300, the other end of the second deflector ring 420 is connected to the water outlet end 130, and an inner diameter D3 of the second deflector ring 420 near the tapered tube 300 is larger than an inner diameter D4 of the second deflector ring 420 near the water outlet end 130. In this embodiment, the water flowing from the first water inlet end 110 and the second water inlet end 120 merges in the tapered tube 300 and continues to flow to the second deflector ring 420, and since the inner diameter D3 of the second deflector ring 420 close to the tapered tube 300 is larger than the inner diameter D4 of the second deflector ring 420 close to the water outlet end 130, the second deflector ring 420 can guide the merged water to flow further towards the inside.
In some embodiments of the present application, the included angle of the cross section of tapered tube 300 is 18 ° to 20 °. In this embodiment, when the included angle of the cross section of the conical tube 300 is 18 ° to 20 °, the spiral water flow can be guided well, and the impact of the pipeline caused by the direct falling of the water flow is avoided.
In some embodiments, the inner diameter of the tapered tube 300 near the flash tank 200 is greater than the inner diameter of the flash tank by 0.1mm to 0.5mm, thereby preventing the water from flowing into the flash tank 200 with a larger step and causing a water flow collision.
