[0020] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0021] Reference Figure 1-4 , an embodiment of a toilet sewage discharge structure of the utility model is proposed:

[0022] A toilet sewage discharge structure includes a barrel body 1 and a seat ring 2. The seat ring 2 includes an upper ring surface 23 connected to the top of the barrel body 1, a lower ring surface 24 located inside the barrel body 1, and a side ring surface 25 connecting the upper ring surface 23 and the lower ring surface 24. The lower ring surface 24 is connected to the inner wall of the barrel body 1, and a plurality of flushing holes 22 are evenly arranged on the edge of the lower ring surface 24. The seat ring 2 has a simple structure and low cost. The seat ring 2 and the inner wall of the barrel body 1 form an annular waterway 21, and the outer side surface of the barrel body 1 is connected to a water inlet pipe 3 connected to the annular waterway 21, and a sewage pipe is arranged at the bottom of the barrel body 1. The flushing hole 22 has a small aperture, and the flow rate of the tap water flowing out of the flushing hole 22 is large, so that the inner wall of the barrel body 1 can be efficiently flushed.

[0023] like Figure 2 As shown, the water inlet pipe 3 includes a water inlet 31 and a water outlet 32 ​​, and the barrel body 1 is provided with a water through hole 11 opposite to the water outlet 32 ​​, and the water through hole 11 is connected to the annular water channel 21 .

[0024] One end of the water inlet pipe 3 is a water outlet 32, and the other end is a connecting groove 33. The bottom of the connecting groove 33 is provided with a water inlet 31. A sealing member 5 is connected to the connecting groove 33. The sealing member 5 is provided with a threaded connection hole 51. The threaded connection hole 51 is used to connect other water pipes. The sealing member 5 is threadedly connected to the connecting groove 33, and the thread of the connecting groove 33 is not shown in the drawings. The sealing member 5 can be used to connect other water pipes and ensure the sealing of the connection between the water pipe and the water inlet pipe 3, and is highly practical.

[0025] The barrel body 1 is provided with two water holes 11 , and the diameter of the water holes 11 is smaller than the water outlet 32 ​​.

[0026] The process of flushing the barrel body 1 of the utility model is as follows: tap water flows into the water inlet pipe 3 from the water inlet 31, and then flows out from the water outlet 32. Since the flow rate = flow rate·cross-sectional area, when the flow rate is equal, the smaller the aperture (cross-sectional area), the greater the flow rate. The tap water flowing out of the water outlet 32 ​​is then divided into two water holes 11. The two water holes 11 are opposite to the water outlet 32. The aperture of the water hole 11 is smaller than that of the water outlet 32, so that the flow rate of the tap water flowing into the annular waterway 21 through the water holes 11 becomes larger, and the tap water fills the annular waterway 21 in two ways. Finally, the tap water in the annular waterway 21 flows out from the flushing hole 22, evenly flushes the inner wall of the barrel body 1, and the water flow rate is large, so that the inner wall of the barrel body 1 is evenly flushed and cleaned.

[0027] The sewage pipe 4 includes a U-shaped channel 41 and a horizontal channel 42 connected to one end of the U-shaped channel 41, and the other end of the U-shaped channel 41 is connected to the barrel 1. When the utility model is not flushing, tap water remains in the U-shaped channel 41 to form a liquid seal to isolate odor.

[0028] The inner cavity of the barrel body 1 gradually decreases from top to bottom, and the flushing hole 22 is arranged in the upper part of the barrel body 1 to ensure that the barrel body 1 can be fully flushed.

[0029] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
