[0030] like Figure 1 to Figure 2 As shown, this embodiment provides an upper sewage pipe 100, which includes a pipe body 110 and a connecting portion 120. The pipe body 110 is connected to the toilet body 400 through the connecting portion 120. The connecting portion 120 is provided with a sewage inlet 121. The sewage inlet 121 is connected to the sewage channel 410 of the toilet body 400. The pipe body 110 is provided with a guide surface 111. The guide surface 111 is located below the sewage inlet 121. The guide surface 111 is recessed away from the sewage inlet 121, and the axis of the sewage inlet 121 passes through the guide surface 111.
[0031] When conducting an artificial specimen flushing test, the artificial specimen enters the sewage inlet 121 of the upper sewage pipe 100 through the sewage channel 410 of the toilet body 400, and then falls to the guide surface 111 below the sewage inlet 121. Since the guide surface 111 is recessed away from the sewage inlet 121, the flow cross-sectional area of the pipe body 110 is expanded, reducing the risk of blockage. Even if more artificial specimens enter the sewage inlet 121 at the same time, since the axis of the sewage inlet 121 passes through the guide surface 111, the artificial specimens at different positions will all fall on the guide surface 111. The guide surface 111 can have a diversion effect on the artificial specimens at different positions, so that the artificial specimens at different positions can pass through one by one in an orderly manner, avoiding the phenomenon of blockage caused by the accumulation of artificial specimens, improving the sewage discharge capacity of the toilet, enhancing the product competitiveness of the toilet, and improving the user experience.
[0032] Optionally, the guide surface 111 is provided with a starting line 112 and an end line 113, the starting line 112 and the end line 113 are respectively located on both sides of the axis of the sewage inlet 121, the distance L1 between the starting line 112 and the axis of the sewage inlet 121 ranges from 30 mm to 36 mm, and the distance L2 between the end line 113 and the axis of the sewage inlet 121 ranges from 17 mm to 23 mm. Since the starting line 112 and the end line 113 are respectively located on both sides of the axis of the sewage inlet 121, the distance between the starting line 112 and the axis of the sewage inlet 121 is greater than the distance between the end line 113 and the axis of the sewage inlet 121, so that artificial specimens at different positions pass smoothly one by one in an orderly manner. It can be understood that the artificial specimen refers to the excrement simulation body used for the test.
[0033] In some embodiments, the tube body 110 is provided with a corner portion 114, and the vertical section and the horizontal section of the tube body 110 are transitionally connected through the corner portion 114, and the distance L3 between the starting line 112 and the corner portion 114 ranges from 57 mm to 63 mm. This arrangement maximizes the flow cross-sectional area of the tube body 110 near the corner portion 114 to ensure smooth passage of the artificial specimen. The inclination angle of the guide surface 111 should not be too large. Optionally, the angle θ between the inclined plane where the starting line 112 and the end line 113 are located and the horizontal plane ranges from 14° to 18°.
[0034] Since the connection between the pipe body 110 and the connecting portion 120 is a vertical section, in order to avoid blockage caused by the direct connection between the flow guide surface 111 and the vertical section, the pipe body 110 is optionally provided with a transition surface 115, and the transition surface 115 is connected to the flow guide surface 111. The transition surface 115 can be a curved surface or an inclined surface, which is not limited here. The inclination angle of the transition surface 115 is greater than that of the flow guide surface 111, so as to facilitate the connection with the vertical section of the pipe body 110.
[0035] In order to facilitate the measurement of whether the installation of the toilet bowl meets the requirements of relevant specifications, the upper sewage pipe 100 optionally further includes a support 130 connected to the pipe body 110, and the support 130 is provided with a measuring surface 131, and the measuring surface 131 is flush with the back of the toilet bowl body 400 close to the wall 500. Before installation, the distance between the measuring surface 131 and the wall 500 can be directly measured to obtain the distance between the back of the toilet bowl body 400 and the wall 500, which is convenient and quick to operate. It can be understood that the measuring surface 131 and the back of the toilet bowl body 400 are both vertical surfaces. Optionally, the distance between the measuring surface 131 and the wall 500 is less than 30 mm, thereby ensuring that the installation of the toilet bowl meets the requirements of relevant specifications.
[0036] This embodiment also provides a shifter, including a lower sewage pipe 200 and the upper sewage pipe 100 mentioned above, the upper sewage pipe 100 is connected to the lower sewage pipe 200, and the lower sewage pipe 200 is connected to the toilet sewage outlet. When conducting an artificial specimen flushing test, the artificial specimen enters the sewage inlet 121 of the upper sewage pipe 100 through the sewage channel 410 of the toilet body 400, and then falls to the guide surface 111 below the sewage inlet 121. Since the guide surface 111 is recessed away from the sewage inlet 121, the flow cross-sectional area of the pipe body 110 is expanded and the risk of blockage is reduced. Even if more artificial specimens enter the sewage inlet 121 at the same time, since the axis of the sewage inlet 121 passes through the guide surface 111, the artificial specimens at different positions will all fall on the guide surface 111. The guide surface 111 can have a guiding effect on the artificial specimens at different positions, so that the artificial specimens at different positions can pass through one by one in an orderly manner, avoiding the accumulation of artificial specimens and blockage, thereby improving the sewage discharge capacity of the toilet, enhancing the product competitiveness of the toilet, and improving the user experience.
[0037] Optionally, the shifter further includes a seal and a locking ring 300, the end of the upper sewage pipe 100 is inserted into the lower sewage pipe 200, the locking ring 300 is connected to the lower sewage pipe 200, the seal is sleeved on the upper sewage pipe 100, one side of the seal is in contact with the end of the lower sewage pipe 200, and the other side of the seal is in contact with the locking ring 300. During installation, the end of the upper sewage pipe 100 is inserted into the lower sewage pipe 200, the seal is sleeved on the upper sewage pipe 100, the locking ring 300 is connected to the lower sewage pipe 200, and the sealing member is locked and fixed to the end of the lower sewage pipe 200 by using the locking ring 300, so as to effectively seal the upper sewage pipe 100 and the lower sewage pipe 200. The seal can adopt a fool-proof design that is symmetrical on both sides, has a simple structure, and is easy to process and form. There is no need to distinguish between the front and back sides of the seal during installation, which reduces the installation difficulty of the shifter and improves the assembly efficiency of the shifter. It eliminates the risk of water leakage due to seal failure caused by reverse installation of the seal, enhances the product competitiveness of the toilet, and improves the user experience.
[0038] This embodiment further provides a toilet, comprising a toilet body 400 and the above-mentioned shifter, wherein the toilet body 400 is connected to the toilet sewage outlet via the shifter. When conducting an artificial specimen flushing test, the artificial specimen enters the sewage inlet 121 of the upper sewage pipe 100 through the sewage channel 410 of the toilet body 400, and then falls to the guide surface 111 below the sewage inlet 121. Since the guide surface 111 is recessed away from the sewage inlet 121, the flow cross-sectional area of the pipe body 110 is expanded and the risk of blockage is reduced. Even if more artificial specimens enter the sewage inlet 121 at the same time, since the axis of the sewage inlet 121 passes through the guide surface 111, the artificial specimens at different positions will all fall on the guide surface 111. The guide surface 111 can have a guiding effect on the artificial specimens at different positions, so that the artificial specimens at different positions can pass through one by one in an orderly manner, avoiding the accumulation of artificial specimens and blockage, thereby improving the sewage discharge capacity of the toilet, enhancing the product competitiveness of the toilet, and improving the user experience.
