[0040] This invention provides a toilet flushing system that can be used in toilets. Figures 1 to 6 This invention illustrates a preferred embodiment of the toilet flushing system provided by the present invention for use in a toilet.

[0041] Please see Figures 1 to 6 In some embodiments, the toilet flushing system 100 includes a flushing pipe 1, a rotating stop 2, and a drive mechanism 3. The flushing pipe 1 includes a connected inlet section 11 and an outlet section 12. The connection between the inlet section 11 and the outlet section 12 forms a communication port 13. The end of the inlet section 11 away from the outlet section 12 is provided with an inlet 14 that connects to the drain outlet 210 of the toilet body 200. The end of the outlet section 12 away from the inlet section 11 is provided with an outlet 15 that connects to the sewer pipe. One end of the rotating stop 2 is rotatably disposed at the inlet section 100. Within water section 11, drive mechanism 3 is power-coupled to rotating stop 2, so as to drive rotating stop 2 to rotate via drive mechanism 3; wherein, when toilet flushing system 100 is in the open state, rotating stop 2 is in the open position, rotating stop 2 and connecting port 13 are offset in the rotation direction of rotating stop 2, and water inlet section 11 is connected to water outlet section 12; when toilet flushing system 100 is in the closed state, rotating stop 2 is in the closed position, rotating stop 2 covers connecting port 13, and water inlet section 11 is isolated from water outlet section 12.

[0042] Specifically, the flushing pipe 1 of the toilet flushing system 100 is located between the drain outlet 210 of the toilet body 200 and the drain pipe. The flushing pipe 1 includes an inlet section 11 and an outlet section 12 connected together, and the connection between the inlet section 11 and the outlet section 12 forms a connecting port 13, so that the two ends of the inlet section 11 and the outlet section 12 are connected through the connecting port 13. The connecting port 13 is located at one end of the inlet section 11, and the end of the inlet section 11 away from the connecting port 13 is provided with an inlet 14, and the end of the outlet section 12 away from the connecting port 13 is provided with an outlet 15. Thus, when the connecting port 13 is open, the inlet section 11 and the outlet section 12 are connected, and the flushing pipe 1 is open; when the connecting port 13 is closed, the inlet section 11 and the outlet section 12 are disconnected, and the flushing pipe 1 is not open.

[0043] The inlet 14 and outlet 15 of the flush pipe 1 are connected to the drain outlet 210 of the toilet body 200 and the drain pipe, respectively. When the flush pipe 1 is open, the water discharged from the drain outlet 210 of the toilet body 200 can enter the inlet section 11 from the inlet 14, then flow into the outlet section 12 from the connecting port 13, and finally be discharged into the drain pipe from the outlet 15. The bottom of the toilet body 200 is usually provided with a drain outlet 230 for the drain pipe to pass through into the toilet body 200, so as to connect the outlet 15 of the flush pipe 1 with the drain pipe.

[0044] The orientation of the inlet 14 is usually opposite to that of the outlet 210, so that the inlet 14 of the flush pipe 1 and the outlet 210 of the toilet body 200 can be connected to each other, thus connecting the inlet 14 of the flush pipe 1 and the outlet 210 of the toilet body 200. The orientation of the inlet 14 and the drain pipe can be the same, opposite, perpendicular, with an acute angle or an obtuse angle. The orientation of the inlet 14 and the drain pipe is usually perpendicular or nearly perpendicular. The following will take the perpendicular orientation of the inlet 14 and the drain pipe as an example, and define the orientation of the inlet 14 as facing forward and the orientation of the drain pipe as facing upward. Then the outlet 210 of the toilet body 200 faces backward, and the outlet 230 is located on the lower rear side of the outlet 210. The outlet 230 penetrates the bottom of the toilet body 200 vertically upward.

[0045] One end of the rotating stop 2 is located inside the water inlet section 11 of the flush pipe 1, and the rotating stop 2 can rotate relative to the flush pipe 1. During the rotation stroke of the rotating stop 2, the rotating stop 2 has an open position and a closed position. The rotating stop 2 can be driven to rotate back and forth between the open position and the closed position by the drive mechanism 3. The drive mechanism 3 can be a motor, a hydraulic cylinder, or a pneumatic cylinder, etc. The following description will take a motor as the drive mechanism 3. During the process of the drive mechanism 3 driving the rotating stop 2 to rotate, the toilet flushing system 100 has an open state and a closed state.

[0046] When the toilet flushing system 100 is in the closed state, the rotating stop 2 is in the closed position. The end of the rotating stop 2 located in the water inlet section 11 completely covers the connecting port 13. At this time, the connecting port 13 is closed, so that the water entering the water inlet section 11 from the water inlet 14 cannot flow into the water outlet section 12 from the connecting port 13, and the flushing pipe 1 is not connected. When the toilet 1000 flushes, the drive mechanism 3 drives the rotating stop 2, which is in the closed position, to rotate to the open position, so that the rotating stop 2 and the connecting port 13 are offset in the rotation direction of the rotating stop 2. At this time, the cover of the connecting port 13 by the rotating stop 2 is released, so that the connecting port 13 is opened, allowing water entering the inlet section 11 from the inlet 14 to flow into the outlet section 12 from the connecting port 13. The flushing pipe 1 is connected, and the toilet flushing system 100, which is in the closed state, switches to the open state, so that water discharged from the drain outlet 210 of the toilet body 200 can enter the flushing pipe 1 from the inlet 14, pass through the flushing pipe 1, and be discharged into the sewer pipe from the outlet 15. When the toilet 1000 finishes flushing, the drive mechanism 3 drives the rotating stop 2, which is in the open position, to rotate to the closed position, so that the rotating stop 2 re-covers the connecting port 13. At this time, the toilet flushing system 100, which is in the open state, switches back to the closed state.

[0047] The toilet flushing system 100 of this utility model controls the connection and disconnection between the toilet body 200 and the drain pipe through the rotating stop 2. When the toilet 1000 is not flushed, the toilet flushing system 100 is in the closed state, and the drive mechanism 3 drives the rotating stop 2 to rotate to the closed position. At this time, the rotating stop 2 can block the toilet body 200 and the drain pipe. When the toilet 1000 is flushed, the toilet flushing system 100 is in the open state, and the drive mechanism 3 drives the rotating stop 2 to rotate to the open position. At this time, the toilet body 200 and the drain pipe are connected through the flushing pipe 1, thereby realizing the flushing function of the toilet 1000. In this way, it is not necessary to set an S-shaped drainage channel between the toilet body 200 and the drain pipe.

[0048] The orientation of the connecting port 13 can be opposite to or the same as the orientation of the inlet 14; the orientation of the connecting port 13 can also be perpendicular to or approximately perpendicular to the orientation of the inlet 14. Optionally, please refer to Figures 1 to 6 In some embodiments, the connecting port 13 is disposed on the pipe side wall of the water inlet section 11, and one end of the rotating stop 2 is disposed in the water inlet section 11 in a way that allows it to rotate circumferentially along the water inlet section 11.

[0049] Specifically, the inlet section 11 is arranged in a cylindrical shape extending in the front-to-back direction. The front end of the inlet section 11 is open, forming an inlet 14. The rear end of the inlet section 11 can be open or closed. A connecting port 13 is provided on the side wall of the inlet section 11. The orientation of the connecting port 13 is perpendicular or approximately perpendicular to the front-to-back direction. The orientation of the connecting port 13 can be upward, downward, left, or right, etc. The following description will take the orientation of the connecting port 13 as upward as an example. The front end of the rotating stop 2 is rotatably disposed within the water inlet section 11 along an upward front-back axis. The portion of the rotating stop 2 within the water inlet section 11 extends beyond the connecting port 13 both forward and backward. Thus, when the rotating stop 2 is in the closed position, the portion of the rotating stop 2 within the water inlet section 11 can completely cover the connecting port 13, thereby completely closing the connecting port 13. Furthermore, when the rotating stop 2 is in the open position, the portion of the rotating stop 2 within the water inlet section 11 can be completely offset from the connecting port 13 in the circumferential direction of the water inlet section 11, thereby completely opening the connecting port 13.

[0050] The specific shape and style of the rotating stop 2 can be set according to the actual situation. Optionally, please refer to [link / reference needed]. Figures 1 to 6 In some embodiments, the rotating stop 2 includes a cylindrical portion 23, one end of which is rotatably fitted inside the water inlet section 11 and located on the side of the connecting port 13 away from the water inlet 14.

[0051] Specifically, the rear end of the rotating stop 2 is provided with a cylindrical part 23, the front end of the cylindrical part 23 extends into the rear end of the water inlet section 11, and the shape of the cylindrical part 23 is adapted to the shape of the water inlet section 11. In this way, the cylindrical part 23 and the water inlet section 11 form a rotational engagement, which can play a rotational guiding role for the rotating stop 2, which is conducive to the drive mechanism 3 driving the rotating stop 2 to rotate smoothly.

[0052] As described above, the rear end of the inlet section 11 can be either open or closed. Optionally, please refer to [link / reference needed]. Figures 1 to 6 In some embodiments, the end of the water inlet section 11 away from the water inlet 14 is provided with an installation port 16 so that one end of the cylindrical part 23 can be inserted into the water inlet section 11 from the installation port 16.

[0053] Specifically, the rear end of the water inlet section 11 is open, forming a rearward mounting port 16 at the rear end of the water inlet section 11. The front end of the cylindrical part 23 can be inserted into the rear end of the water inlet section 11 through the mounting port 16. Thus, the mounting port 16 at the rear end of the water inlet section 11 facilitates the installation of the rotating stop 2 at the rear end of the water inlet section 11.

[0054] Optionally, please refer to Figures 1 to 6 In some embodiments, an annular boss 24 is provided on the outer peripheral surface of the end of the cylindrical portion 23 located outside the water inlet section 11, and the annular boss 24 abuts against the end of the water inlet section 11 where the installation port 16 is provided.

[0055] Specifically, the rear end of the cylindrical part 23 extends backward from the mounting port 16 to the outside of the water inlet section 11. An annular boss 24 extending circumferentially along the cylindrical part 23 is provided on the outer peripheral surface of the rear end of the cylindrical part 23. The annular boss 24 is located outside the water inlet section 11 and abuts against the rear side of the rear end of the water inlet section 11. In this way, the rotating stop 2 can be installed and positioned on the flushing pipe 1 by the abutting and cooperation between the annular boss 24 and the water inlet section 11 in the front and rear upward.

[0056] Optionally, please refer to Figures 1 to 6 In some embodiments, a first annular mounting groove 25 is provided on the outer peripheral surface of one end of the cylindrical portion 23 located in the water inlet section 11, and a sealing ring 4 is provided at the first annular mounting groove 25.

[0057] Specifically, a first annular mounting groove 25 or multiple first annular mounting grooves 25 arranged at intervals are provided on the outer peripheral surface of the portion of the cylindrical part 23 located inside the water inlet section 11. A sealing ring 4 is provided at each first annular mounting groove 25. Thus, by providing a sealing ring 4 between the cylindrical part 23 and the water inlet section 11, the sealing performance of the flushing pipe 1 at the installation port 16 can be ensured.

[0058] Optionally, please refer to Figures 1 to 6In some embodiments, the toilet flushing system 100 further includes a rear cover 5, which covers one end of the cylindrical portion 23 away from the water inlet 14 and the other end of the water inlet section 11 away from the water inlet 14. The drive mechanism 3 is disposed on the rear cover 5 and is poweredly coupled to the end of the cylindrical portion 23 away from the water inlet 14.

[0059] Specifically, the front end of the cylindrical part 23 is sealed to prevent water in the inlet section 11 from flowing backward through the cylindrical part 23 to the installation port 16. The rear end of the cylindrical part 23 is open, and the rear cover 5 covers the rear end of the cylindrical part 23 and the rear end of the inlet section 11. The drive mechanism 3 is mounted on the rear cover 5, and the drive end of the drive mechanism 3 extends forward from the rear end of the cylindrical part 23 into the cylindrical part 23 and connects to the cylindrical part 23. This makes the structure of the flushing pipe 1, the rotating stop 2, and the drive mechanism 3 more compact, which helps to minimize the front-to-back and upward dimensions of the toilet flushing system 100.

[0060] Optionally, please refer to Figures 1 to 6 In some embodiments, a baffle portion 21 is provided at one end of the rotating stop 2 located inside the water inlet section 11. The shape of the baffle portion 21 is adapted to the shape of the water inlet section 11. The baffle portion 21 and the inner pipe sidewall of the water inlet section 11 form a sliding guide fit in the rotation direction of the rotating stop 2. When the rotating stop 2 is in the open position, the baffle portion 21 and the connecting port 13 are offset in the rotation direction of the rotating stop 2. When the rotating stop 2 is in the closed position, the baffle portion 21 covers the connecting port 13.

[0061] Specifically, the baffle portion 21 protrudes from the front end face of the cylindrical portion 23. The baffle portion 21 is arranged in an arcuate plate shape extending circumferentially along the cylindrical portion 23, so that the shape of the baffle portion 21 matches the shape of the water inlet section 11, allowing the baffle portion 21 to fit against the inner pipe sidewall of the water inlet section 11 and slide along the inner pipe sidewall of the water inlet section 11. The front end of the baffle portion 21 is located in front of the connecting port 13, and the rear end of the baffle portion 21 is located behind the connecting port 13. When the rotating stop 2 is in the open position, the baffle portion 21 and the connecting port 13 are completely offset in the rotation direction of the rotating stop 2, so that the connecting port 13 is fully open. When the rotating stop 2 is in the closed position, the baffle portion 21 can completely cover the connecting port 13, so that the connecting port 13 is completely closed.

[0062] Further, please refer to Figures 1 to 6In some embodiments, a guide vane 22 extending axially along the water inlet section 11 is protruding from the surface of the baffle portion 21 near the central axis. The guide vane 22 not only serves to guide the water flowing from the water inlet 14 into the water inlet section 11 towards the connecting port 13, but also strengthens the structural strength of the baffle portion 21. A single guide vane 22 may be provided; alternatively, multiple guide vanes 22 may be provided at intervals along the rotation direction of the rotating stop member 2.

[0063] Optionally, please refer to Figures 1 to 6 In some embodiments, the height of the guide vane 22 protruding from the baffle portion 21 gradually increases in the direction away from the inlet 14. The height of the guide vane 22 protruding from the baffle portion 21 is the width of the guide vane 22. The width of the guide vane 22 gradually increases from front to back, so that the guide vane 22 is arranged in a triangular or right trapezoidal shape, which can improve the guiding effect of the guide vane 22.

[0064] Optionally, please refer to Figures 1 to 6 In some embodiments, the end of the inlet section 11 near the inlet 14 is used to be fitted over the drain outlet 210, and a first annular seal 6 is provided between the inlet section 11 and the drain outlet 210. Thus, by providing the first annular seal 6 between the front end of the inlet section 11 and the drain outlet 210, the sealing between the flushing pipe 1 and the drain outlet 210 can be ensured.

[0065] The first annular seal 6 is located inside the flush pipe 1. The specific shape and style of the first annular seal 6 can be set according to the actual situation. Optionally, please refer to Figures 1 to 6 In some embodiments, an annular stop surface 17 facing the inlet 14 is provided on the inner pipe side wall of the water inlet section 11. The first annular seal 6 includes an annular sealing part 61 and an annular sleeve part 62. The annular sealing part 61 is located on the side of the annular stop surface 17 near the inlet 14 and is sandwiched between the annular stop surface 17 and the drain outlet 210. One end of the annular sleeve part 62 is connected to the annular sealing part 61 and is sleeved between the drain outlet 210 and the water inlet section 11.

[0066] Specifically, an annular stop surface 17 facing forward is provided on the inner pipe side wall at the front end of the water inlet section 11. The annular stop surface 17 is located behind the water inlet 14 and in front of the rotating stop 2. The front end of the water inlet section 11 is sleeved outside the drain outlet 210. When the flushing pipe 1 of the toilet flushing system 100 is installed on the drain outlet 210, the annular stop surface 17 abuts against the rear side of the end face of the drain outlet 210, thus enabling the flushing pipe 1 to be installed and positioned on the drain outlet 210.

[0067] The annular sealing part 61 is located on the front side of the annular stop surface 17. The annular sealing part 61 is attached to the annular stop surface 17, and the annular stop surface 17 and the end face of the drain port 210 clamp the annular sealing part 61 from the front and back. The annular sleeve part 62 is arranged in a cylindrical shape extending in the front and back direction. The annular sleeve part 62 is located on the front side of the annular sealing part 61. The annular sleeve part 62 is clamped inside and outside by the outer peripheral side of the drain port 210 and the inner pipe side wall at the front end of the water inlet section 11. This arrangement of the shape of the first annular seal 6 allows the sealing path of the first annular seal 6 to be extended and bent multiple times, thereby improving the sealing performance between the flush pipe 1 and the drain port 210.

[0068] Further, please refer to Figures 1 to 6 In some embodiments, an annular rib 18 is provided on the annular stop surface 17, and the annular sleeve part 62 is sleeved between the drain port 210 and the annular rib 18; the first annular seal 6 also includes an annular lip 63, one end of the annular lip 63 is inserted between the annular rib 18 and the inner pipe side wall of the water inlet section 11, and the other end of the annular lip 63 is connected to the end of the annular sleeve part 62 away from the annular seal part 61.

[0069] Specifically, an annular rib 18 protrudes forward on the annular stop surface 17. The annular rib 18 is cylindrical and extends along the front and rear. The outer peripheral side of the annular rib 18 is spaced apart from the inner pipe sidewall of the water inlet section 11, so as to form an annular slot 19 with the groove facing forward between the annular rib 18 and the inner pipe sidewall of the water inlet section 11. The front end of the annular sleeve 62 bends outward and backward to form an annular lip 63. At least a portion of the annular lip 63 is inserted into the annular slot 19. In this way, the insertion and engagement between the annular lip 63 and the annular slot 19 can not only realize the installation and positioning of the first annular seal 6 in the front end of the flush pipe 1, but also prevent the first annular seal 6 from becoming loose.
