[0046] The present invention provides a toilet flushing system, and this toilet flushing system can be used in a toilet. Figures 1 to 11 Multiple embodiments of the toilet flushing system provided by the present invention used in a toilet are shown.

[0047] Please refer to Figures 1 to 11 , in some embodiments, the toilet flushing system 100 includes a housing 1, a movable member 2, and a driving mechanism 3. An flushing channel 11 is formed inside the housing 1. Both ends of the flushing channel 11 penetrate through the housing 1 to form a water inlet 12 and a water outlet 13. The water inlet 12 and the water outlet 13 are respectively used to communicate with the sewage outlet 210 and the sewer pipe of the toilet body 200. One end of the movable member 2 is movably arranged inside the housing 1. The driving mechanism 3 is power-coupled to the movable member 2 to drive the movable member 2 to move inside the housing 1 through the driving mechanism 3. Wherein, when the toilet flushing system 100 is in the open state, the movable member 2 is located at a first position, and the water inlet 12 is communicated with the water outlet 13 so that the water entering the flushing channel 11 from the water inlet 12 can be discharged from the water outlet 13. When the toilet flushing system 100 is in the closed state, the movable member 2 is located at a second position, and at least a part of the movable member 2 is located inside the flushing channel 11 and blocks between the water inlet 12 and the water outlet 13.

[0048] Specifically, the housing 1 of the toilet flushing system 100 is arranged between the sewage outlet 210 and the sewer pipe of the toilet body 200. The housing 1 is a hollow structure, and an flushing channel 11 is formed inside the housing 1. Both ends of the flushing channel 11 in the extending direction of the flushing channel 11 penetrate through the wall of the housing 1 respectively, so as to form a water inlet 12 and a water outlet 13 on the housing 1.

[0049] The water inlet 12 and the water outlet 13 of the shell 1 are connected to the sewage outlet 210 of the toilet body 200 and the sewer pipe respectively, so that when the flushing channel 11 is connected, the water discharged from the sewage outlet 210 of the toilet body 200 can enter the flushing channel 11 from the water inlet 12, and after passing through the flushing channel 11, it is discharged into the sewer pipe from the water outlet 13. The direction of the water inlet 12 is usually opposite to the direction of the sewage outlet 210, and the direction of the water outlet 13 is also usually opposite to the direction of the access port of the sewer pipe. The direction of the water outlet 13 and the direction of the water inlet 12 can be the same, opposite, perpendicular, acute angle or obtuse angle. The following will take the direction of the water outlet 13 perpendicular to the direction of the water inlet 12 as an example for introduction, and define the direction of the water outlet 13 as downward and the direction of the water inlet 12 as forward.

[0050] The movable member 2 can be movably arranged on the housing 1. In the movable stroke of the movable member 2, the movable member 2 has a first position and a second position. The movable member 2 can be driven to move back and forth between the first position and the second position by the driving mechanism 3, wherein the driving mechanism 3 can be a motor, a hydraulic cylinder or a pneumatic cylinder, etc. In the process of the driving mechanism 3 driving the movable member 2 to move, the toilet flushing system 100 has an open state and a closed state.

[0051] When the toilet flushing system 100 is in a closed state, the movable part 2 is located in the second position, at least a portion of the movable part 2 is located in the flushing channel 11 and between the water inlet 12 and the water outlet 13, and the shape of the portion of the movable part 2 located in the flushing channel 11 is adapted to the shape of the flushing channel 11, so that the portion of the movable part 2 located in the flushing channel 11 can block the flushing channel 11, so that water entering the flushing channel 11 from the water inlet 12 cannot pass through the movable part 2 and flow to the water outlet 13. When the toilet 1000 is flushed, the driving mechanism 3 drives the movable member 2 located at the second position to move to the first position, so that the movable member 2 can withdraw from the flushing channel 11 or water can pass through the movable member 2, so that the blockage of the flushing channel 11 by the movable member 2 is released, and the flushing channel 11 is now connected, and the toilet flushing system 100 in the closed state is switched to the open state, so that the water discharged from the sewage outlet 210 of the toilet body 200 can enter the flushing channel 11 from the water inlet 12, and after passing through the flushing channel 11, it is discharged into the sewer pipe from the water outlet 13. When the toilet 1000 finishes flushing, the driving mechanism 3 drives the movable member 2 located at the first position to move to the second position, so that the movable member 2 re-blocks the flushing channel 11, and the toilet flushing system 100 in the open state is switched back to the closed state.

[0052] The toilet flushing system 100 of the present invention controls the connection and isolation between the toilet body 200 and the sewer pipe through the movable part 2. When the toilet 1000 is not flushed, the toilet flushing system 100 is in a closed state, and the driving mechanism 3 drives the movable part 2 to move to the second position. At this time, the movable part 2 can block the flushing channel 11 between the toilet body 200 and the sewer pipe; when the toilet 1000 is flushed, the toilet flushing system 100 is in an open state, and the driving mechanism 3 drives the movable part 2 to move to the first position. At this time, the flushing channel 11 between the toilet body 200 and the sewer pipe is connected, thereby realizing the flushing function of the toilet 1000, so that there is no need to set an S-shaped drainage channel between the toilet body 200 and the sewer pipe.

[0053] The specific shape of the movable part 2 can be set according to the actual situation. For example, the movable part 2 can be set in a cylindrical, rod-shaped or block-shaped shape. Figures 1 to 4 In some embodiments, the movable part 2 is a sealing cylinder 2a, and a mounting cavity 14 extending along the axial direction of the sealing cylinder 2a is formed inside the shell 1. One end of the mounting cavity 14 is connected to the flushing channel 11, and one end of the sealing cylinder 2a can be movably arranged in the mounting cavity 14.

[0054] Specifically, the housing 1 is provided with a flushing channel 11 and a mounting cavity 14 that are interconnected. One end of the sealing cylinder 2a can be movably disposed in the mounting cavity 14, and at least a portion of the sealing cylinder 2a can extend into the flushing channel 11 from the connection between the mounting cavity 14 and the flushing channel 11. The shape of the movable part 2 is usually compatible with the shape of the mounting cavity 14 and the shape of the flushing channel 11, so that the inner surface of the mounting cavity 14 and the inner surface of the flushing channel 11 can serve as a movable guide for the movable part 2. The axial direction of the sealing cylinder 2a can be up and down, front and back, or left and right, etc., and the following will take the axial direction of the sealing cylinder 2a as the up and down direction, and the end of the sealing cylinder 2a close to the flushing channel 11 as the lower end of the sealing cylinder 2a as an example for introduction. Then the mounting cavity 14 is extended in the up and down direction, and the lower end of the mounting cavity 14 is connected to the flushing channel 11.

[0055] The drive mechanism 3 may be located inside the housing 1; the drive mechanism 3 may also be located outside the housing 1; the drive mechanism 3 may also be partially located outside the housing 1 and partially located inside the housing 1. Figures 1 to 4 In some embodiments, the driving mechanism 3 is located outside the shell 1; one end of the installation cavity 14 away from the flushing channel 11 penetrates the shell 1 to form an installation port 16, and part of the sealing tube 2a extends from the installation port 16 to the outside of the shell 1 and is connected to the driving mechanism 3.

[0056] Specifically, the driving mechanism 3 is located outside the housing 1. The upper end of the installation cavity 14 penetrates the housing 1 upward, so as to form an upward installation opening 16 on the housing 1. In this way, the sealing cylinder 2a can be installed into the housing 1 downward from the installation opening 16. This not only makes the installation of the sealing cylinder 2a more convenient, but also facilitates the connection between the upper end of the sealing cylinder 2a and the driving mechanism 3.

[0057] The lower end of the installation cavity 14 is communicated with the flushing channel 11. The specific shape and style of the flushing channel 11 can be set according to the actual situation. Optionally, please refer to Figures 1 to 4 , in some embodiments, the flushing channel 11 includes a first connecting section 111, a second connecting section 112, a third connecting section 113 and a fourth connecting section 114. The first connecting section 111 is arranged to extend along the radial direction of the sealing cylinder 2a, and one end of the first connecting section 111 is provided with a water inlet 12; the second connecting section 112 is arranged to extend along the axial direction of the sealing cylinder 2a, and one end of the second connecting section 112 is communicated with the end of the first connecting section 111 far from the water inlet 12 and the installation cavity 14; the third connecting section 113 is arranged in parallel with the first connecting section 111, the third connecting section 113 is communicated with the end of the second connecting section 112 far from the first connecting section 111, and the third connecting section 113 and the first connecting section 111 are located on the same side of the second connecting section 112; the fourth connecting section 114 is arranged to extend along the axial direction of the sealing cylinder 2a, one end of the fourth connecting section 114 is communicated with the end of the third connecting section 113 far from the second connecting section 112, and the end of the fourth connecting section 114 far from the third connecting section 113 is provided with a water outlet 13.

[0058] Specifically, the first connecting section 111 and the third connecting section 113 are arranged to extend along the front-back direction, while the second connecting section 112 and the fourth connecting section 114 are arranged to extend along the up-down direction. The front end of the first connecting section 111 is provided with a water inlet 12, and the rear end of the first connecting section 111 is communicated with the upper end of the second connecting section 112. The second connecting section 112 is located below the installation cavity 14, the upper end of the second connecting section 112 is communicated with the lower end of the installation cavity 14, and the lower end of the second connecting section 112 is communicated with the rear end of the third connecting section 113. The upper end of the fourth connecting section 114 is communicated with the front end of the third connecting section 113, the lower end of the fourth connecting section 114 is provided with a water outlet 13, and an arc transition section is usually arranged between the upper end of the fourth connecting section 114 and the front end of the third connecting section 113.

[0059] Furthermore, please refer to Figures 1 to 4 , in some embodiments, one end of the first connecting section 111 close to the water inlet 12 is used to sleeved outside the sewage outlet 210, and an annular abutting surface 115 facing away from the second connecting section 112 is arranged on the inner surface of the first connecting section 111, and the annular abutting surface 115 is used to abut against the sewage outlet 210.

[0060] Specifically, the front end of the first connecting section 111 is sleeved outside the sewage outlet 210, and a forward-facing annular abutting surface 115 is provided on the inner surface of the first connecting section 111. The annular abutting surface 115 is located at the rear side of the water inlet 12. When the housing 1 of the toilet flushing system 100 is installed on the sewage outlet 210, the annular abutting surface 115 abuts against the rear side of the end face of the sewage outlet 210, so that the installation positioning of the housing 1 on the sewage outlet 210 can be realized.

[0061] There are various specific movement modes of the sealing cylinder 2a. For example, the movement mode of the sealing cylinder 2a can be moving or rotating, etc. Optionally, please refer to Figure 1 and Figure 2 , in some embodiments, one end of the sealing cylinder 2a is movably arranged in the installation cavity 14 along the axial direction of the sealing cylinder 2a; when the moving member 2 is in the first position, the end of the sealing cylinder 2a close to the flushing channel 11 retracts into the installation cavity 14; when the moving member 2 is in the second position, the end of the sealing cylinder 2a close to the flushing channel 11 enters the flushing channel 11 and blocks between the water inlet 12 and the water outlet 13.

[0062] Specifically, the sealing cylinder 2a is movably arranged up and down in the installation cavity 14. Hereinafter, the sealing cylinder 2a that can move up and down is defined as the first sealing cylinder. When the moving member 2 is in the second position, the lower end of the first sealing cylinder enters the upper end of the second connecting section 112 from the connection between the second connecting section 112 and the installation cavity 14, so that the lower end of the first sealing cylinder can block the upper end of the second connecting section 112, preventing the water in the first connecting section 111 from flowing into the second connecting section 112. When the moving member 2 is in the first position, the lower end of the first sealing cylinder withdraws from the second connecting section 112 and completely enters the installation cavity 14, releasing the blockage of the upper end of the second connecting section 112 by the lower end of the first sealing cylinder, so that the water in the first connecting section 111 can flow into the second connecting section 112.

[0063] Furthermore, please refer to Figure 1 and Figure 2 , in some embodiments, an annular abutting platform 15 extending along the circumferential direction of the sealing cylinder 2a is provided on the inner surface of the flushing channel 11; when the moving member 2 is in the second position, the end face of the sealing cylinder 2a close to the flushing channel 11 abuts against the annular abutting platform 15.

[0064] Specifically, an annular abutting platform 15 protrudes from the inner surface of the second connecting section 112, and the annular abutting platform 15 is located below the first sealing cylinder. When the moving member 2 moves down to the second position, the lower end face of the first sealing cylinder abuts against the annular abutting platform 15 up and down. In this way, by providing the annular abutting platform 15 on the inner surface of the flushing channel 11, the movement positioning of the first sealing cylinder at the second position can be realized.

[0065] Optionally, please refer toFigures 3 to 6 In some embodiments, one end of the sealing cylinder 2a is located within the flushing channel 11, and the end of the sealing cylinder 2a remote from the flushing channel 11 is rotatably arranged within the installation cavity 14 along the central axis of the sealing cylinder 2a. A first communication port 21 and a second communication port 22 which are in communication with each other are formed in one end of the sealing cylinder 2a located within the flushing channel 11. When the movable member 2 is in the first position, the first communication port 21 and the second communication port 22 are respectively in communication with the water inlet 12 and the water outlet 13. When the movable member 2 is in the second position, the first communication port 21 is offset from the water inlet 12 or the second communication port 22 is offset from the water outlet 13.

[0066] The rotation direction of the sealing cylinder 2a can be set according to the actual situation. For example, the sealing cylinder 2a can rotate along the up-down axis or the front-back axis. Optionally, please refer to Figure 3 and Figure 4 In some embodiments, the first communication port 21 and the second communication port 22 are respectively formed on the circumferential side surface and the end surface of one end of the sealing cylinder 2a located within the flushing channel 11, and the second communication port 22 communicates with the first communication port 21 and the water outlet 13. When the movable member 2 is in the first position, the first communication port 21 and the water inlet 12 are opposite to each other in the extending direction of the flushing channel 11, so that the first communication port 21 is in communication with the water inlet 12. When the movable member 2 is in the second position, the first communication port 21 and the water inlet 12 are offset from each other in the extending direction of the flushing channel 11.

[0067] Specifically, the axial direction of the sealing cylinder 2a is up-down, and the sealing cylinder 2a is rotatably arranged within the installation cavity 14 along the up-down axis (i.e., the central axis of the sealing cylinder 2a). Hereinafter, the sealing cylinder 2a capable of rotating along the up-down axis is defined as the second sealing cylinder. The second sealing cylinder is of a hollow structure. The lower end of the second sealing cylinder is located within the upper end of the second communication section 112. The first communication port 21 is formed on the outer circumferential side surface of the lower end of the second sealing cylinder, and the second communication port 22 is formed on the lower end surface of the second sealing cylinder. When the second sealing cylinder is in the first position, the first communication port 21 and the rear end of the first communication section 111 are opposite to each other front and back. At this time, the water in the first communication section 111 can flow into the second sealing cylinder from the first communication port 21, and then flow out of the second sealing cylinder from the second communication port 22 and enter the second communication section 112. In this way, the water in the first communication section 111 can pass through the lower end of the second sealing cylinder and enter the second communication section 112. When the drive mechanism 3 drives the second sealing cylinder in the first position to rotate to the second position, so that the first communication port 21 and the rear end of the first communication section 111 are offset from each other in the rotation direction of the second sealing cylinder, at this time, the unperforated part on the outer circumferential side surface of the lower end of the second sealing cylinder blocks the water in the first communication section 111, so that the water in the first communication section 111 cannot pass through the lower end of the second sealing cylinder and enter the second communication section 112.

[0068] Optionally, refer to Figure 5 and Figure 6 , in some embodiments, at one end face and the peripheral side face of the sealing cylinder 2a located inside the flushing channel 11, a first communication port 21 and a second communication port 22 are respectively opened. The first communication port 21 communicates with the second communication port 22 and the water inlet 12. When the movable member 2 is in the first position, the second communication port 22 is opposite to the water outlet 13 in the extending direction of the flushing channel 11, so that the second communication port 22 communicates with the water outlet 13. When the movable member 2 is in the second position, the second communication port 22 is offset from the water outlet 13 in the extending direction of the flushing channel 11.

[0069] Specifically, the axial direction of the sealing cylinder 2a is the front-back direction. The sealing cylinder 2a is rotatably arranged in the installation cavity 14 along the front-back axis (i.e., the central axis of the sealing cylinder 2a). Hereinafter, the sealing cylinder 2a that can rotate along the front-back axis is defined as the third sealing cylinder. The third sealing cylinder is a hollow structure. The front end of the third sealing cylinder is located inside the upper end of the second communication section 112. The front end face of the third sealing cylinder is provided with the first communication port 21, and the outer peripheral side face of the front end of the third sealing cylinder is provided with the second communication port 22. When the third sealing cylinder is in the first position, the second communication section 112 is vertically opposite to the water outlet 13. At this time, the water in the first communication section 111 can flow into the third sealing cylinder from the first communication port 21, and then flow out of the third sealing cylinder from the second communication port 22 and enter the second communication section 112. In this way, the water in the first communication section 111 can pass through the lower end of the third sealing cylinder and enter the second communication section 112. When the drive mechanism 3 drives the third sealing cylinder in the first position to rotate to the second position, so that the second communication port 22 is offset from the water outlet 13 in the rotation direction of the third sealing cylinder. At this time, the unperforated part on the outer peripheral side face of the front end of the third sealing cylinder blocks the water in the first communication section 111, so that the water in the first communication section 111 cannot pass through the front end of the third sealing cylinder and enter the second communication section 112.

[0070] Further, refer to Figure 5 and Figure 6 , in some embodiments, a guide vane 25 protrudes from the inner cylinder wall of the sealing cylinder 2a. The guide vane 25 can not only play a role in guiding the water, so as to guide the water flowing into the third sealing cylinder from the first communication port 21 to the second communication port 22, but also play a role in strengthening the structural strength of the third sealing cylinder.

[0071] Optionally, refer to Figures 1 to 4 , in some embodiments, a sealing ring 4 is sleeved outside the sealing cylinder 2a.

[0072] Specifically, a sealing ring 4 is usually sleeved outside the sealing cylinder 2a to ensure the sealing performance between the sealing cylinder 2a and the housing 1. For example, one or more first sealing rings can be provided on the first sealing cylinder. When the first sealing cylinder is in the second position, the first sealing ring is located in the installation cavity 14 and is adjacent to the connection between the installation cavity 14 and the flushing channel 11. For another example, one or more second sealing rings and one or more third sealing rings can be provided at the lower end of the second sealing cylinder. The second sealing ring is adjacent to the upper side of the connection between the first connection section 111 and the second connection section 112, and the third sealing ring is adjacent to the lower side of the connection between the first connection section 111 and the second connection section 112.

[0073] Optionally, please refer to Figure 1 and Figure 2 , in some embodiments, an annular gasket 8 is provided on the lower end surface of the first sealing cylinder.

One end of the movable member 2 close to the water inlet 12 is closed, and a first annular protrusion 23a protrudes from the outer peripheral surface. The first annular protrusion 23a forms the blocking portion 23.

[0078] Specifically, the movable member 2 is arranged in a cylindrical shape extending along the front-back direction. The front end of the movable member 2 is closed, and a first annular protrusion 23a protrudes from the outer peripheral surface of the front end of the movable member 2. The outer diameter of the first annular protrusion 23a is greater than or equal to the inner diameter of the part of the flushing channel 11 close to the water inlet 12. In this way, the part of the front end of the movable member 2 provided with the first annular protrusion 23a forms the blocking portion 23. Hereinafter, the case where the front end of the movable member 2 is provided with the first annular protrusion 23a will be taken as an example for introduction.

[0079] Furthermore, please refer to Figures 7 to 10 , in some embodiments, an annular mounting groove 231 is arranged on the circumferential side surface of the first annular protrusion 23a, and a sealing ring 4 is arranged at the annular mounting groove 231.

[0080] Specifically, the sealing ring 4 is arranged on the circumferential side surface of the first annular protrusion 23a, so that the first annular protrusion 23a contacts the inner surface of the housing 1 through the sealing ring 4. In this way, the sealing performance between the blocking portion 23 and the housing 1 can be ensured.

[0081] Optionally, please refer toFigures 7 to 10 In some embodiments, the flushing channel 11 includes a water inlet section 116 and a water outlet section 117.
