[0039] This invention provides a toilet flushing system that can be used in toilets. Figures 1 to 3 This invention illustrates a preferred embodiment of the toilet flushing system provided by the present invention for use in a toilet.

[0040] Please see Figures 1 to 3In some embodiments, the toilet flushing system 100 includes a housing 1, a partition 2, and a drive mechanism 3. The housing 1 has an inlet 11 and an outlet 12, which are used to connect the drain outlet 210 of the toilet body 200 and the drain pipe (not shown in the figure), respectively. The partition 2 is rotatably disposed inside the housing 1. The drive mechanism 3 is poweredly coupled to the partition 2 to drive the partition 2 to rotate inside the housing 1. When the toilet flushing system 100 is in the open state, the partition 2 is in the open position, and the inlet 11 and the outlet 12 are connected to allow water entering the housing 1 from the inlet 11 to be discharged from the outlet 12. When the toilet flushing system 100 is in the closed state, the partition 2 is in the closed position, and the partition 2 is spaced between the inlet 11 and the outlet 12.

[0041] Specifically, the housing 1 of the toilet flushing system 100 is located between the drain outlet 210 of the toilet body 200 and the drain pipe. The housing 1 has a hollow structure, and an inner cavity is formed inside the housing 1. The housing 1 has an inlet 11 and an outlet 12 that communicate with the inner cavity. At least a portion of the inner cavity forms a flushing channel 14 that communicates with the inlet 11 and the outlet 12.

[0042] The inlet 11 and outlet 12 of the housing 1 are respectively connected to the drain outlet 210 of the toilet body 200 and the drain pipe. Thus, when the flushing channel 14 is open, water discharged from the drain outlet 210 of the toilet body 200 can enter the flushing channel 14 through the inlet 11, and then be discharged into the drain pipe through the outlet 12. The bottom of the toilet body 200 is usually provided with a connecting opening 230 for the drain pipe to pass through, facilitating the connection between the outlet 12 of the housing 1 and the drain pipe. The orientation of the inlet 11 is usually opposite to that of the drain outlet 210, allowing the inlet 11 of the housing 1 and the drain outlet 210 of the toilet body 200 to interlock, thus connecting the inlet 11 of the housing 1 and the drain outlet 210 of the toilet body 200. The orientation of the water inlet 11 and the drain pipe can be the same, opposite, perpendicular, or have an acute or obtuse angle. The orientation of the water inlet 11 and the drain pipe is usually perpendicular or nearly perpendicular. The following will take the orientation of the water inlet 11 being perpendicular to the drain pipe as an example. We define the orientation of the water inlet 11 as facing forward and the orientation of the drain pipe as facing upward. Then, the orientation of the drain outlet 210 of the toilet body 200 is facing backward. The connecting port 230 is located on the lower rear side of the drain outlet 210 and extends vertically through the bottom of the toilet body 200.

[0043] The partition 2 is located inside the cavity of the housing 1. One end of the partition 2 is rotatably connected to the inner shell surface of the housing 1, allowing the partition 2 to rotate relative to the housing 1. During the rotation stroke of the partition 2, the partition 2 has an open position and a closed position. The partition 2 can be driven to rotate back and forth between the open and closed positions by a drive mechanism 3. The drive mechanism 3 can be a motor, hydraulic cylinder, or pneumatic cylinder, etc. The following description will use a motor as an example of the drive mechanism 3. During the rotation of the partition 2 driven by the drive mechanism 3, the toilet flushing system 100 has an open state and a closed state.

[0044] When the toilet flushing system 100 is in the closed state, the partition 2 is in the closed position. At least a portion of the partition 2 is flipped into the flushing channel 14 between the inlet 11 and the outlet 12. The shape of the portion of the partition 2 in the flushing channel 14 is adapted to the shape of the flushing channel 14, so that the portion of the partition 2 in the flushing channel 14 can block the flushing channel 14. Thus, water entering the flushing channel 14 from the inlet 11 cannot pass through the partition 2 and flow to the outlet 12. When the toilet 1000 flushes, the drive mechanism 3 drives the partition 2, which is in the closed position, to flip to the open position, so that the partition 2 retracts outside the flushing channel 14. This releases the blockage of the flushing channel 14 by the partition 2, opening the flushing channel 14. The toilet flushing system 100, which was in the closed state, switches to the open state, allowing water discharged from the drain outlet 210 of the toilet body 200 to enter the flushing channel 14 from the inlet 11, pass through the flushing channel 14, and then drain into the sewer pipe from the outlet 12. When the toilet 1000 finishes flushing, the drive mechanism 3 drives the partition 2, which was in the open position, to flip to the closed position, so that the partition 2 re-blocks the flushing channel 14. The toilet flushing system 100, which was in the open state, then switches back to the closed state.

[0045] The toilet flushing system 100 of this utility model controls the connection and isolation between the toilet body 200 and the drain pipe through the partition 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 partition 2 to flip to the closed position. At this time, the partition 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 partition 2 to flip to the open position. At this time, the toilet body 200 and the drain pipe are connected through the housing 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.

[0046] As described above, the inlet 11 faces forward, and the orientation of the inlet 11 and the outlet 12 can be the same, opposite, perpendicular, or at an acute or obtuse angle. When the outlet 12 faces downward, the outlet 12 of the housing 1 can be connected to the drain pipe; the outlet 12 of the housing 1 can also be connected to the drain pipe through a corrugated pipe or other conduit. When the outlet 12 faces backward, that is, when the orientation of the inlet 11 and the outlet 12 are opposite, the outlet 12 of the housing 1 can be connected to the drain pipe through a corrugated pipe or other conduit.

[0047] Optionally, please refer to Figures 1 to 3 In some embodiments, the orientation of the inlet 11 is opposite to that of the outlet 12. The flushing channel 14 extends in a front-to-back direction, with the front end of the flushing channel 14 penetrating the housing 1 to form the inlet 11 and the rear end of the flushing channel 14 penetrating the housing 1 to form the outlet 12. The following description will use the flushing channel 14 extending in a front-to-back direction as an example.

[0048] As described above, at least a portion of the shell cavity forms a flushing channel 14 connecting the inlet 11 and the outlet 12. The flushing channel 14 can be formed entirely within the shell cavity, i.e., the flushing channel 14 is part of the shell cavity; alternatively, a portion of the shell cavity can also form the flushing channel 14. Optionally, please refer to... Figures 1 to 3 In some embodiments, the interior of the housing 1 has a connected flushing channel 14 and a mounting cavity 15. The two ends of the flushing channel 14 penetrate the housing 1 to form an inlet 11 and an outlet 12, respectively. The mounting cavity 15 is located on one side of the flushing channel 14. When the partition 2 is in the open position, the partition 2 is located in the mounting cavity 15. When the partition 2 is in the closed position, part of the partition 2 flips into the flushing channel 14 and blocks the space between the inlet 11 and the outlet 12.

[0049] Specifically, the mounting cavity 15 is located on one side of the flushing channel 14 in a direction perpendicular to the front-back direction. For example, the mounting cavity 15 can be located on the left, right, or upper side of the flushing channel 14. Optionally, please refer to... Figures 1 to 3 In some embodiments, the mounting cavity 15 is located on the side of the flushing channel 14 away from the drain pipe, that is, the mounting cavity 15 is located on the upper side of the flushing channel 14. The following will be an example of the mounting cavity 15 being located on the upper side of the flushing channel 14 and directly above the connecting port 230.

[0050] One end of the partition 2 is rotatably mounted on the front wall of the mounting cavity 15 along a left-right upward axis, allowing the partition 2 to flip up and down. When the partition 2 is flipped up to the open position, the surface of the partition 2 is perpendicular or nearly perpendicular to the vertical direction, and the entire partition 2 is located within the mounting cavity 15. When the partition 2 is flipped down to the closed position, the surface of the partition 2 is perpendicular or nearly perpendicular to the front-back direction, and the free end of the partition 2 flips into the flushing channel 14, blocking the space between the inlet 11 and the outlet 12.

[0051] Further, please refer to Figures 1 to 3 In some embodiments, the end of the mounting cavity 15 away from the flushing channel 14 penetrates the housing 1 to form a mounting opening 16, and a cover plate 5 is provided at the mounting opening 16.

[0052] Specifically, the upper end of the mounting cavity 15 extends upward through the housing 1 to form an upward-facing mounting opening 16, allowing the partition 2 to be installed inside the housing 1 through the mounting opening 16. The cover plate 5 is typically sealed to the mounting opening 16 by a detachable connection such as a threaded connection or a snap-fit ​​connection, so that after the partition 2 is installed inside the housing 1, the mounting opening 16 of the housing 1 can be sealed by the cover plate 5.

[0053] Optionally, please refer to Figures 1 to 3 In some embodiments, an annular stop portion 13 is provided on the inner shell surface of the housing 1 near the water inlet 11. The annular stop portion 13 extends circumferentially along the water inlet 11 and is located on the side of the partition 2 near the water inlet 11. When the partition 2 is in the closed position, the plate surface of the partition 2 near the water inlet 11 abuts against the annular stop portion 13 so that the partition 2 blocks the water inlet 11 and the water outlet 12.

[0054] Specifically, an annular stop 13 is protruding from the inner shell surface at the front end of the housing 1. The annular stop 13 is positioned close to the water inlet 11, located behind the water inlet 11 and in front of the partition 2. When the partition 2 moves forward to the closed position, the partition 2 and the annular stop 13 abut against each other. Thus, by providing the annular stop 13 on the inner shell surface of the housing 1, not only can the partition 2 be positioned in the closed position, but it also helps to ensure the sealing effect of the partition 2 in the closed position on the flushing channel 14.

[0055] Further, please refer to Figures 1 to 3 In some embodiments, the end of the housing 1 near the water inlet 11 is used to be fitted over the drain outlet 210, and the drain outlet 210 abuts against the side of the annular stop portion 13 near the water inlet 11.

[0056] Specifically, the front end of the housing 1 is fitted over the drain outlet 210. When the housing 1 of the toilet flushing system 100 is installed on the drain outlet 210, the annular stop 13 abuts against the rear side of the end face of the drain outlet 210, thus enabling the housing 1 to be installed and positioned on the drain outlet 210.

[0057] Optionally, please refer to Figures 1 to 3 In some embodiments, an annular seal 4 is provided at the annular stop portion 13. Thus, the annular seal 4 at the annular stop portion 13 ensures the sealing performance of the housing 1 at the annular stop portion 13.

[0058] The specific shape and style of the annular stop 13 can be set according to the actual situation. Optionally, please refer to Figures 1 to 3 In some embodiments, the annular stop portion 13 is provided with an annular stop surface 131 facing the water inlet 11. The annular seal 4 includes a first annular seal portion 41, a second annular seal portion 42, an annular connecting portion 43, and an annular sleeve portion 44. The first annular seal portion 41 is located on the side of the annular stop portion 13 away from the water inlet 11. When the partition 2 is in the closed position, the first annular seal portion 41 is clamped between the annular stop portion 13 and the partition 2. The second annular seal portion 42 is located on the side of the annular stop portion 13 close to the water inlet 11. The second annular seal portion 42 is connected to the first annular seal portion 41 through the annular connecting portion 43. The second annular seal portion 42 is clamped between the annular stop surface 131 and the drain outlet 210. One end of the annular sleeve portion 44 is connected to the second annular seal portion 42. The annular sleeve portion 44 is sleeved between the drain outlet 210 and the annular stop portion 13.

[0059] Specifically, the annular stop portion 13 has a forward-facing annular stop surface 131 on its inner peripheral side. The first annular sealing portion 41 is attached to the rear end face of the annular stop portion 13. When the partition 2 is in the closed position, the rear end face of the annular stop portion 13 and the partition 2 clamp the first annular sealing portion 41 from the front and back. The second annular sealing portion 42 is located inside the annular stop portion 13 and in front of the annular stop surface 131. The second annular sealing portion 42 is attached to the annular stop surface 131, and the annular stop surface 131 and the end face of the drain port 210 clamp the second annular sealing portion 42 from the front and back. An annular connecting portion 43 connects the first annular sealing portion 41 and the second annular sealing portion 42. The annular connecting portion 43 is located behind the annular stop surface 131 and is attached to the inner peripheral side of the annular stop portion 13. The annular sleeve portion 44 is arranged in a cylindrical shape extending in the front-rear direction. The annular sleeve portion 44 is located in front of the second annular sealing portion 42. The annular sleeve portion 44 is sandwiched between the outer peripheral side of the drain port 210 and the inner peripheral side of the annular stop portion 13. This arrangement of the shape of the annular seal 4 allows the sealing path of the annular seal 4 to be extended and bent multiple times, thereby improving the sealing performance of the housing 1 at the annular stop portion 13.

[0060] Further, please refer to Figures 1 to 3 In some embodiments, an annular stop portion 13 is provided with an annular slot 132 on the end face near the water inlet 11, and the annular seal 4 also includes an annular lip 45, one end of the annular lip 45 is inserted into the annular slot 132, and the other end of the annular lip 45 is connected to the end of the annular sleeve portion 44 away from the second annular seal portion 42.

[0061] Specifically, the annular stop portion 13 has an annular slot 132 with the groove facing forward on its front end surface, and the annular sleeve portion 44 has its front end bent outward and backward to form an annular lip 45. At least part of the annular lip 45 is inserted into the annular slot 132. In this way, through the insertion and engagement between the annular lip 45 and the annular slot 132, not only can the annular seal 4 be installed and positioned at the annular stop portion 13, but the annular seal 4 can also be prevented from becoming loose.

[0062] The partition 2 is flipped by the drive mechanism 3. The drive mechanism 3 can be located inside the housing 1; the drive mechanism 3 can also be located outside the housing 1; or the drive mechanism 3 can be partially located outside the housing 1 and partially located inside the housing 1. Optionally, please refer to [link to relevant documentation]. Figures 1 to 3In some embodiments, the drive mechanism 3 is disposed on the outer surface of the housing 1, and the drive end of the drive mechanism 3 extends into the housing 1 and connects to the partition 2. The main body of the drive mechanism 3 is located outside the housing 1 and is fixedly installed on the housing 1. The drive end (i.e., the drive shaft) of the drive mechanism 3 passes through the shell wall of the housing 1 and extends into the housing 1. The part of the drive shaft of the drive mechanism 3 that extends into the housing 1 is connected to the partition 2. Thus, when the drive mechanism 3 is running, the drive shaft of the drive mechanism 3 can drive the partition 2 to rotate.

[0063] This utility model also provides a toilet. Figures 1 to 3 A preferred embodiment of the toilet provided by this utility model is shown.
