To simplify the disclosure of the present application, specific example components and configurations are described below. Of course, these are for illustrative purposes only and are not intended to limit the present application.

Although examples of various specific processes and materials are provided in the present application, those skilled in the art may recognize the application of other processes and / or the use of other materials.

[0016] In some situations, in a toilet with a rotatable waste discharge pipe, the drive motor of the waste discharge pipe and the waste discharge pipe are arranged side by side in the front and rear, and the axis of the output shaft of the drive motor and the rotation axis of the waste discharge pipe are collinear, so that the size of the toilet expands in the front and rear direction, the volume of the toilet is large, and it occupies a large space.

[0017] An embodiment of the present application provides a waste discharge box assembly for a toilet, in which a waste discharge pipe of the waste discharge box assembly can be rotated within the waste discharge box to switch between an initial state and a waste discharge state, thereby realizing waste discharge from the toilet in the waste discharge state.

[0018] As shown in Figures 1 to 3, a toilet waste discharge box assembly according to an embodiment of the present application comprises a waste discharge box 1, a waste discharge pipe 2 and a drive device 3, the waste discharge box 1 comprises a waste discharge inlet 11 and a waste discharge outlet 12, the waste discharge pipe 2 is installed within the waste discharge box 1, and the inlet end 21 of the waste discharge pipe 2 is connected to the waste discharge inlet 11.

[0019] The drive device 3 comprises a drive element 31 and a transmission mechanism 32, the drive element 31 is connected to the waste discharge pipe 2 via the transmission mechanism 32 and is configured to rotate and drive the waste discharge pipe 2 to switch between an initial state and a waste discharge state, and the axis 311 of the output shaft of the drive element 31 is not collinear with the rotation axis 22 of the waste discharge pipe 2.

[0020] In the toilet waste discharge box assembly according to the embodiment of the present application, the function of rotating the waste discharge pipe 2 to switch between the initial state and the waste discharge state is realized by the drive device 3. Figures 2 and 3 show structural schematic diagrams of the toilet waste discharge box assembly according to one embodiment of the present application when it is in the initial state and the waste discharge state, respectively, and the direction of the arc-shaped arrow in the figures indicates the rotation direction of the waste discharge pipe 2 when switching between the initial state and the waste discharge state.

[0021] The waste discharge inlet 11 of the waste discharge box 1 is used as an inlet for external wastewater, and the waste discharge outlet 12 of the waste discharge box 1 is used as an outlet for wastewater flowing through the waste discharge box 1. The waste discharge pipe 2 is installed inside the waste discharge box 1 and is used to guide the wastewater entering through the waste discharge inlet 11. The inlet end 21 of the waste discharge pipe 2 is connected to the waste discharge inlet 11, so that wastewater outside the waste discharge box assembly flows into the lumen of the waste discharge pipe 2 via the waste discharge inlet 11 and the inlet end 21 of the waste discharge pipe 2, and finally flows out from the waste discharge outlet 12 of the waste discharge box 1.

[0022] The driving device 3 is used to provide power support for the rotation of the waste discharge pipe 2 to switch between the initial state and the waste discharge state. The driving device 3 includes a driving element 31 and a transmission mechanism 32. The driving element 31 provides the driving force for the switching operation of the waste discharge pipe 2 between the initial state and the waste discharge state, and the transmission mechanism 32 is used to transmit the driving force provided by the driving element 31 to the waste discharge pipe 2. As shown in FIG. 1 , the driving element 31 is connected to the waste discharge pipe 2 via the transmission mechanism 32, so that the driving force provided by the driving element 31 is transmitted to the waste discharge pipe 2 via the transmission mechanism 32. The initial position and operating range of the driving element 31 and the transmission mechanism 32 may be preset, so that the waste discharge pipe 2 can be driven to rotate within a specified range of motion to switch the waste discharge pipe 2 between the initial state and the waste discharge state. As a result, the drive device 3 can rotate and drive the waste discharge pipe 2 to switch between the initial state shown in FIG. 2 and the waste discharge state shown in FIG.

[0023] 1, the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the waste discharge pipe 2 are not collinear, but are set to have a certain distance between them. In contrast, if the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the waste discharge pipe 2 are collinear, the drive element 31 and the waste discharge pipe 2 are arranged side by side along the direction of the rotation axis 22 of the waste discharge pipe 2 (for example, the front-to-rear direction), which increases the size of the toilet in the front-to-rear direction, and increases the volume of the toilet and the installation space it occupies. By setting the axis 311 of the output shaft of the driving element 31 and the rotation axis 22 of the waste discharge pipe 2 so that they are not collinear, the driving element 31 and the waste discharge pipe 2 are avoided from being arranged side by side along the direction of the rotation axis 22 of the waste discharge pipe 2, which is beneficial to reducing the size of the waste discharge box assembly in the direction of the rotation axis 22 of the waste discharge pipe 2, thereby shortening the size of the entire waste discharge box assembly in the direction of the rotation axis 22, saving more internal space of the toilet where the waste discharge box assembly is located and meeting other structural design requirements, and beneficial to reducing the size of the entire toilet in the direction of the rotation axis 22 of the waste discharge pipe 2, reducing the volume of the toilet and the installation space it occupies, and expanding the application range of the toilet.

[0024] In some exemplary embodiments, as shown in FIG. 1 , the toilet waste discharge box assembly has a drive unit 24 installed in the waste discharge pipe 2, which cooperates with the transmission of the transmission mechanism 32, and the drive unit 24 is installed opposite the waste discharge inlet 11, and the drive element 31 and the waste discharge inlet 11 are respectively located on opposite sides of the waste discharge pipe 2.

[0025] As shown in FIG. 1, a drive unit 24 that cooperates with the transmission of the transmission mechanism 32 is installed in the sewage discharge pipe 2, an installation cavity 13 is installed in the sewage discharge box 1, the drive unit 24 is rotatably installed in the installation cavity 13, and a rotary connection part 4 that connects with the drive unit 24 is further installed in the installation cavity 13, and the transmission mechanism 32 is connected to the drive unit 24 via the rotary connection part 4.

[0026] An attachment cavity 13 for mounting and accommodating the driver 24 and the rotary connector 4 is provided at the end of the waste discharge box 1 opposite the waste discharge inlet 11, so that the driver 24 and the waste discharge inlet 11 are disposed opposite each other. As shown in FIGS. 4 to 7 , the rotary connector 4 is provided with a protruding rib 41, and the driver 24 is a groove that engages with the rib 41. The engagement between the rib 41 and the groove establishes a power transmission connection between the rotary connector 4 and the waste discharge pipe 2, and the rotary connector 4 is connected to the transmission mechanism 32, so that the driving force of the driver 3 is transmitted to the waste discharge pipe 2, driving the waste discharge pipe 2 to perform a smooth and stable reversal movement, thereby enabling the waste discharge pipe 2 to smoothly switch between its initial state and its waste discharge state.

[0027] In the embodiment shown in Figures 1 and 8, the driving element 31 and the waste discharge inlet 11 are respectively installed on opposite sides of the waste discharge pipe 2, so that the axis 311 of the output shaft of the driving element 31 and the rotation axis 22 of the waste discharge pipe 2 are not collinear, which contributes to reducing the size of the waste discharge box assembly in the direction of the rotation axis 22 of the waste discharge pipe 2.

[0028] In some exemplary embodiments, as shown in Figures 1 and 8, a waste discharge inlet 11 is installed on a first side (e.g., the left side in Figures 1 and 8) of the waste discharge box 1, a protruding waste discharge outlet 12 is installed on a second side (e.g., the lower side in Figures 1 and 8) adjacent to the first side of the waste discharge box 1, the driving element 31 is installed outside the waste discharge box 1 and is located on the second side of the waste discharge box 1, and the driving element 31 is located on the side of the waste discharge outlet 12 away from the waste discharge inlet 11, and the axis 311 of the output shaft of the driving element 31 and the rotation axis 22 of the waste discharge pipe 2 are parallel to each other.

[0029] As shown in Figures 1 and 8, a wastewater discharge inlet 11 is provided on a first side (e.g., the left side in Figures 1 and 8) of the wastewater discharge box 1, and is used as an inlet for wastewater to enter the wastewater discharge box assembly. A protruding wastewater discharge outlet 12 is provided on a second side (e.g., the lower side in Figures 1 and 8) adjacent to the first side of the wastewater discharge box 1, and is used as an outlet for wastewater to flow through the wastewater discharge pipe 2. By providing the driving element 31 outside the wastewater discharge box 1, separation of water and electricity is achieved, and the safety of the driving element 31 is improved. The drive element 31 is located on the second side of the waste discharge box 1, and the drive element 31 is located on the side of the waste discharge outlet 12 away from the waste discharge inlet 11, so that the drive element 31 is stored using the space on the side of the protruding waste discharge outlet 12 away from the waste discharge inlet 11, which helps to reduce the volume of the waste discharge box assembly, and in this case the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the waste discharge pipe 2 are parallel but not collinear.

[0030] 1 and 8, the axis 311 of the output shaft of the drive element 31 of the waste discharge box assembly is arranged parallel to the rotation axis 22 of the waste discharge pipe 2. This parallel arrangement facilitates the arrangement of a transmission mechanism 32 between the drive element 31 and the waste discharge pipe 2. For example, a general-purpose transmission mechanism 32, such as a chain, belt, or rack, can be arranged between the axis 311 and the rotation axis 22 to transmit the driving force of the drive element 31 to the waste discharge pipe 2. This structure allows the design of the transmission mechanism 32 to be simple and inexpensive, and the size occupied by the transmission mechanism 32 in the direction of the rotation axis 22 is relatively small, achieving the function of rotating the waste discharge pipe 2 while not occupying much space outside the waste discharge box 1. This reduces the size of the entire waste discharge box assembly in the direction of the rotation axis 22, saving more interior space in the toilet where the waste discharge box assembly is located and meeting other structural design requirements.

[0031] In some exemplary embodiments, as shown in Figures 1 to 3, the transmission mechanism 32 includes a driving wheel 321, a driven wheel 322, and a transmission belt 323, where the driving wheel 321 is connected to the driving element 31, the driven wheel 322 is connected to the driving unit 24, and the transmission belt 323 is fitted around the outside of the driving wheel 321 and the driven wheel 322.

[0032] 1 to 3, the transmission mechanism 32 includes a driving wheel 321, a driven wheel 322, and a transmission belt 323. The driving wheel 321 and the driven wheel 322 may both be gears, and the transmission belt 323 may be a gear belt. Compared with a conventional flat belt pulley transmission mechanism, the transmission using gears and gear belts is more stable and less slippery, with a smaller transmission contact surface, less relative wear, and a longer lifespan. The transmission mechanism 32 uses a pulley, which is relatively low cost, simple in structure, and easy to install and adjust, and is suitable for switching the waste discharge reversal of some small toilet waste discharge boxes with relatively small transmission power.

[0033] The driving wheel 321 is connected to and fixed to the output shaft of the driving element 31, the driven wheel 322 is connected to the driving unit 24 via the rotary connection part 4, and the transmission belt 323 is fitted to the outside of the driving wheel 321 and the driven wheel 322. As a result, the driving element 31 transmits driving force to the waste discharge pipe 2 via the driving wheel 321, the driven wheel 322, the transmission belt 323, the rotary connection part 4, and the driving unit 24, and drives the waste discharge pipe 2 to switch between the initial state and the waste discharge state (as shown in Figures 2 and 3).

[0034] In some other exemplary embodiments, as shown in Figures 8 to 10, the transmission mechanism 32 includes a driving gear 324, a driven gear 325, and a rack 326, the driving gear 324 is connected to the driving element 31, the driven gear 325 is connected to the driving unit 24, and both the driving gear 324 and the driven gear 325 mesh with the rack 326 to transmit power.

[0035] In the embodiment shown in Figures 8 to 10, the transmission mechanism 32 includes a drive gear 324, a driven gear 325, and a rack 326. The rack 326 may be a national standard straight rack, which is relatively inexpensive and easy to replace, test, and adjust. The drive gear 324 is connected to and fixedly attached to the output shaft of the drive element 31. The driven gear 325 is connected to the drive unit 24 via the rotary connection 4. The rack 326 is located on the same side of the drive gear 324 and the driven gear 325 and is meshed with the drive gear 324 and the driven gear 325 to transmit power. Thus, the drive element 31 transmits driving force to the waste discharge pipe 2 via the drive gear 324, the rack 326, the driven gear 325, the rotary connection 4, and the drive unit 24, driving the waste discharge pipe 2 to switch between the initial state and the waste discharge state (as shown in Figures 9 and 10).

[0036] Furthermore, in some exemplary embodiments, as shown in Figures 11 to 13, a drive unit 24 that cooperates with the transmission of the transmission mechanism 32 is installed in the sewage discharge pipe 2, and the drive unit 24 is installed opposite the sewage discharge inlet 11, and the drive element 31 and the sewage discharge inlet 11 are respectively located on opposite sides of the sewage discharge pipe 2.

[0037] The waste discharge pipe 2 is provided with a drive unit 24 that cooperates with the transmission of the transmission mechanism 32, a mounting cavity 13 is provided in the waste discharge box 1, the drive unit 24 is rotatably installed in the mounting cavity 13, a rotary connector 4 that connects with the drive unit 24 is further provided in the mounting cavity 13, and the transmission mechanism 32 is connected to the drive unit 24 via the rotary connector 4. The mounting cavity 13 may be provided at the end opposite the waste discharge inlet 11 of the waste discharge box 1, and is used to mount and accommodate the drive unit 24 and the rotary connector 4, so that the drive unit 24 and the waste discharge inlet 11 are installed opposite each other. The rotary connection part 4 is provided with a protruding rib 41, and the drive part 24 is a groove that engages with the rib 41. The engagement between the rib 41 and the groove realizes a transmission connection between the rotary connection part 4 and the sewage discharge pipe 2, and the rotary connection part 4 is connected to the transmission mechanism 32, so that the driving force of the drive unit 3 is transmitted to the sewage discharge pipe 2 to drive the smooth and stable reversal movement of the sewage discharge pipe 2, thereby smoothly realizing the switching of the sewage discharge pipe 2 between the initial state and the sewage discharge state.

[0038] In the embodiment shown in Figures 11 to 13, the drive element 31 and the waste discharge inlet 11 are respectively installed on opposite sides of the waste discharge pipe 2, but the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the waste discharge pipe 2 are not collinear; for example, the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the waste discharge pipe 2 may be installed perpendicular to each other, which also contributes to reducing the size of the waste discharge box assembly in the direction of the rotation axis 22.

[0039] In the embodiment shown in Figures 11 to 13, the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the sewage discharge pipe 2 are installed perpendicularly, and a transmission member that changes the transmission direction, such as a turbo worm, a helical gear, etc., is installed between the drive element 31 and the drive unit 24, thereby enabling the drive device 3 to drive the drive unit 24 and the sewage discharge pipe 2, thereby further expanding the spatial range for the arrangement of the drive element 31 and the transmission mechanism 32 and the type of the transmission mechanism 32, and the axis 311 of the output shaft of the drive element 31 and the rotation axis 22 of the sewage discharge pipe 2 are not necessarily perpendicular.

[0040] In the embodiment shown in Figures 11 to 13, the transmission mechanism 32 includes a worm 327 and a helical gear 328, the worm 327 is connected to the driving element 31, the helical gear 328 is connected to the driving unit 24, and the worm 327 and the helical gear 328 mesh with each other to transmit power.

[0041] The transmission mechanism 32 includes a worm 327 and a helical gear 328. The worm 327 is connected to and fixedly installed on the output shaft of the driving element 31, and the helical gear 328 is connected to the driving part 24 via the rotary connection part 4, and the worm 327 and the helical gear 328 mesh with each other to transmit power. Thus, the driving element 31 drives the waste discharge pipe 2 via the worm 327, the helical gear 328, the rotary connection part 4, and the driving part 24 to achieve reverse switching operation.

[0042] In any of the above exemplary embodiments, as shown in Figures 1 to 3 and Figures 8 to 13, the waste discharge pipe 2 is an arc-shaped pipe, the inlet end 21 of the waste discharge pipe 2 is fitted into the waste discharge inlet 11, and the rotation axis 22 of the waste discharge pipe 2 and the central axis of the waste discharge inlet 11 are collinear.

[0043] By fitting the inlet end 21 of the waste discharge pipe 2 into the waste discharge inlet 11, wastewater outside the waste discharge box assembly flows into the waste discharge pipe 2 through the waste discharge inlet 11 and the inlet end 21 of the waste discharge pipe 2. A sealed connection is formed between the inlet end 21 of the waste discharge pipe 2 and the waste discharge inlet 11, thereby preventing wastewater leakage. By fitting the inlet end 21 of the waste discharge pipe 2 into the waste discharge inlet 11, the rotation axis 22 of the waste discharge pipe 2 and the central axis of the waste discharge inlet 11 are collinear, which allows the waste discharge inlet 11 to support the waste discharge pipe 2, allowing the waste discharge pipe 2 to rotate around the common central axis of the waste discharge pipe 2 and the waste discharge inlet 11. When the waste discharge pipe is reversed, it will not separate from the waste discharge inlet 11, causing water leakage.

[0044] In any of the above exemplary embodiments, in the waste discharge state, the outlet end 23 of the waste discharge pipe 2 faces the waste discharge outlet 12, and in the initial state, the outlet end 23 of the waste discharge pipe 2 faces away from the waste discharge outlet 12 and is in a water-sealed state.

[0045] 2-3, 9-10, and 12-13 show structural schematic diagrams of the waste discharge box assembly in its initial state and waste discharge state. The waste discharge box assembly in FIGS. 2, 9, and 12 is in its initial state, with the outlet end 23 of the waste discharge pipe 2 moving away from the waste discharge outlet 12. At this time, the outlet end 23 of the waste discharge pipe 2 faces upward and is at or above the water seal surface in the toilet body 5 (e.g., higher than the water seal surface), so the waste discharge pipe 2 is in a water-sealed state, preventing water from flowing out of the waste discharge box 1 within the toilet body 5 and achieving the odor-preventing function of the water seal. The waste discharge box assembly shown in Figures 3, 10 and 13 is in a waste discharge state, with the outlet end 23 of the waste discharge pipe 2 facing toward the waste discharge outlet 12. At this time, the outlet end 23 of the waste discharge pipe 2 faces downward, whereby wastewater in the toilet body 5 is introduced through the waste discharge inlet 11 and the waste discharge pipe 2 and flows out through the waste discharge outlet 12, thereby realizing the waste discharge function. The waste discharge pipe 2 reverses and switches from the initial state shown in Figures 2, 9 and 12 to the waste discharge state shown in Figures 3, 10 and 13, and from the waste discharge state shown in Figures 3, 10 and 13 to the initial state shown in Figures 2, 9 and 12, which is performed by the drive unit 3, and the arc arrows in the figures indicate the rotation direction of the waste discharge pipe 2.

[0046] The process of switching operation between the initial state and the waste discharge state performed by the waste discharge pipe 2 of the waste discharge box assembly is as follows.

[0047] When the waste discharge pipe 2 of the waste discharge box assembly is in its initial state, the outlet end 23 of the waste discharge pipe 2 is away from the waste discharge outlet 12, and the height of the water seal surface inside the toilet body 5 is below the outlet end 23 of the waste discharge pipe 2, so that the seal water in the toilet body 5 does not flow out of the waste discharge pipe 2 and the water seal function is realized. When the drive device 3 receives a state switching command, the drive element 31 drives the waste discharge pipe 2 to rotate clockwise via the transmission mechanism 32 and the drive unit 24, and the waste discharge pipe 2 reaches the waste discharge state, at which time the outlet end 23 of the waste discharge pipe 2 moves toward the waste discharge outlet 12 and enters the waste discharge state.

[0048] When the waste discharge pipe 2 of the waste discharge box assembly is in the waste discharge state, the outlet end 23 of the waste discharge pipe 2 faces the waste discharge outlet 12, and wastewater in the toilet body 5 flows into the waste discharge pipe 2 of the waste discharge box assembly and flows out from the waste discharge outlet 12. The drive device 3 receives a state switching command, and the drive element 31 drives the waste discharge pipe 2 to rotate counterclockwise via the transmission mechanism 32 and the drive unit 24, until the waste discharge pipe 2 reaches its initial state, at which time the outlet end 23 of the waste discharge pipe 2 moves away from the waste discharge outlet 12 and is above the height of the water sealing surface of the toilet body 5, so that the waste discharge pipe 2 enters the initial water sealing state.

[0049] As can be understood, the initial state of the waste discharge pipe 2 does not have to be a water-sealed state, that is, in the initial state, the outlet end 23 of the waste discharge pipe 2 may be lower than the height of the water-sealed surface of the toilet body 5, and in this case, the water-sealing function may be realized by other structures.

[0050] An embodiment of the present application further provides a toilet, as shown in FIG. 14, comprising a toilet body 5, the toilet body 5 having a waste discharge outlet 51, and the toilet further comprising a toilet waste discharge box assembly as described in any of the above exemplary embodiments, wherein the waste discharge outlet 51 of the toilet body 5 is in communication with the waste discharge inlet 11 of the waste discharge box assembly.
