Further, referring to fig. 2, the distance between the center of the water outlet 231 and the lower surface of the seat part 200 should be set to enable the water flow flowing out through the water outlet 231 to flow against the lower surface of the seat part 200, specifically, the distance between the center of the water outlet 231 and the lower surface of the seat part 200 may be set to be 10mm to 50mm, and further, the distance between the center of the water outlet 231 and the lower surface of the seat part 200 may be set to be 25mm; after the water flows out of the water outlet 231, the water flows under the action of surface tension and is firstly jointed with the lower surface of the seat ring part 200, then continuously jointed with the water guide wall 120 to flow onto the wall surface of the urinal cavity 110 under the action of gravity, and the water flows out of the water outlet 231 and is always jointed with the wall surface of the closestool body to flow instead of directly rushing towards the wall surface, so that the impact of the water flow on the wall surface can be reduced. Referring to fig. 2 and 3, in a direction in which the water passing chamber 230 extends toward the water outlet 231, the cross-sectional area of the water passing chamber 230 is gradually increased, and more particularly, the water passing chamber 230 may be configured to have a conical shape so that water flow can more smoothly flow through the water passing chamber 230, and a space through which water flows is gradually increased in a process in which water flows toward the water outlet 231 in the extending direction of the water passing chamber 230, so that the speed of water flow can be gradually increased. In summary, the water flowing out through the water outlet 231 can flow against the lower surface of the seat portion 200, and the cross-sectional area of the water passing chamber 230 gradually increases in the direction along the extending direction of the water passing chamber 230 toward the water outlet 231, so that the air involved in the collision between the water flow and the wall surface can be reduced, the dispersion of the water flow can be suppressed, the splashing can be reduced, and the flushing effect of the water flow on the wall surface of the toilet chamber 110 can be improved.

Further, referring to fig. 2, the water passing chamber 230 is located below the annular water channel 220, and under the action of gravity, the flushing water in the annular water channel 220 can flow to the water passing chamber 230 more smoothly, on one hand, enough water can be guaranteed to flow into the water passing chamber 230 and be flushed out from the water outlet 231, so as to guarantee the flushing effect; on the other hand, the flushing water is not easy to remain in the annular water channel 220, and when the toilet body performs flushing operation, the water flow passing through the annular water channel 220 is not easy to be disturbed by the water remaining in the annular water channel 220 in the previous flushing operation, so that the water flow flushed out from the water outlet 231 is not easy to be disturbed, the water flow dispersion is further inhibited, the splashing is further reduced, and the pollution to the toilet environment is reduced.

After the water flows out from the water outlet 231 provided in the seat portion 200, the water flows may collide with the lower surface of the seat portion 200 to be caught in air due to the closer distance between the water outlet 231 and the lower surface of the seat portion 200, so that the water flows are dispersed to generate splashed water. Based on this, referring to fig. 1 and 2, the lower surface of the seat portion 200 has a guide groove 240, and the guide groove 240 communicates with the water outlet 231 and extends in a direction away from the water outlet 231, and the cross-sectional area of the guide groove 240 gradually decreases in a direction away from the water outlet 231. The guide groove 240 can increase the distance between the water flow, which is flushed from the water outlet 231, and the lower surface of the seat part 200 to reduce the impact force of the water flow colliding with the lower surface of the seat part 200; the cross-sectional area of the guide groove 240 is gradually reduced in a direction away from the water outlet 231, the guide groove 240 can buffer and guide the water flow, and the impact force of the water flow colliding with the lower surface of the seat part 200 is reduced, and the water flow flowing into the guide groove 240 can smoothly generate a downward inclined speed after passing through the guide groove 240, so that the water flow smoothly falls onto the water guide wall 120, the air involved in the collision between the water flow and the water guide wall 120 is further reduced, the water flow dispersion is suppressed, the splash is reduced, and the pollution to the bathroom environment is reduced.

Further, referring to fig. 2 and 4, the water guide wall 120 is connected to the inner wall of the urinal cavity 110 through the arc surface 130, and after water flows out from the water outlet 231, the water flows onto the water guide wall 120 and flows along the water guide wall 120, and meanwhile, part of water is continuously diverted from the water flow and flows into the inner wall of the urinal cavity 110, and the arc surface 130 can smoothly connect the water guide wall 120 with the inner wall of the urinal cavity 110, so that the water flow on the water guide wall 120 can smoothly flow to the inner wall of the urinal cavity 110 along with the arc surface 130, thereby preventing the water flow from emptying, and further enabling the water flow to better cover the inner wall of the urinal cavity 110 and guaranteeing the flushing effect.

The water flow is dropped onto the water guide wall 120 after being flushed out from the water outlet 231, and gradually flows from the water guide wall 120 to the inner wall of the urinal cavity 110 while flowing on the water guide wall 120, so that the water flow on the water guide wall 120 is smoothly branched to the inner wall of the urinal cavity 110, and the water guide wall 120 is inclined downward in a direction from the outside of the urinal cavity 110 to the inside of the urinal cavity 110 with reference to fig. 2 and 4, and the water flow flows along the circumferential direction of the water guide wall 120 under the action of inertia after being flushed out from the water outlet 231 and simultaneously flows along the downwardly inclined water guide wall 120 to the inner wall of the urinal cavity 110 under the action of gravity, so that the water flow on the water guide wall 120 can be smoothly branched to the inner wall of the urinal cavity 110; moreover, the water guide wall 120 which is inclined downwards can prevent flushing water from remaining on the water guide wall 120, and when the toilet body is flushed, the water flow passing through the water guide wall 120 is not easily disturbed by water remaining on the water guide wall 120 in the last flushing operation, so that the water flow flushed from the water outlet 231 is not easily disturbed, the water flow dispersion is further inhibited, and the splashing is further reduced.

Referring to fig. 1 and 2, the main body 100 further has a waste inlet chamber 140 connected to the urinal chamber 110, the urinal chamber 110 has opposite front and rear ends, and the distance between the front end and the connection point of the waste inlet chamber 140 and the urinal chamber 110 is greater than the distance between the rear end and the connection point of the waste inlet chamber 140 and the urinal chamber 110, so that the angle between the inner wall of the urinal chamber 110 and the horizontal plane is gradually reduced in the direction from the rear end to the front end; based on this, the included angle between the water guide wall 120 and the horizontal plane is gradually reduced in the direction from the rear end to the front end so as to adapt to the angle change of the inner wall of the urinal cavity 110, so that water flow can smoothly flow from the water guide wall 120 to the inner wall of the urinal cavity 110 at any position in the circumferential direction of the urinal cavity 110, and the inner wall of the urinal cavity 110 can be sufficiently flushed.

It will be appreciated that the difference between the maximum and minimum angles of the water guiding wall 120 and the horizontal plane may be set according to practical requirements, for example, referring to fig. 5, the angle between the water guiding wall 120 and the horizontal plane at the rear end of the urinal cavity 110 is R1, referring to fig. 6, the angle between the water guiding wall 129 and the horizontal plane at the front end of the urinal cavity 110 is R2, and may be set to be 5 ° -R1-R2 +.10 °.
