[0052] like Figures 1 to 16 As shown, this application provides a sewage box, which includes a box body 1 and a sewage pipe 2. The box body 1 is provided with a box inlet 11 and a box outlet 12. The box body 1 can be fixed on a ceramic body 10 so that the outlet 101 of the ceramic body 10 is connected to the box inlet 11. The sewage pipe 2 is provided with a sewage inlet 221 and a sewage outlet 222. The angle between the axis of the sewage outlet 222 and the axis of the sewage inlet 221 is α, where 0° < α ≤ 90°. The sewage inlet 221 is connected to the box inlet 11. The axis of the sewage inlet 221 is located above the axis of the outlet 101. The sewage pipe 2 rotates within the box body 1 along the axis of the sewage inlet 221 so that the sewage outlet 222 revolves around the axis of the sewage inlet 221.

[0053] Using the above-mentioned drain box, the axis of drain outlet 222 ( Figure 2 The X-ray in the image) and the axis of the inlet 221 ( Figure 2The angle between the Y-line and the inlet 221 is α, where 0° < α ≤ 90°, to create a storage space between the inlet 221 and the outlet 222. Thus, when the outlet 222 is located above the axis of the inlet 221, the horizontal plane at the lowest point of the outlet 222 is the plane of the water cover (e.g., ...). Figure 8 The water seal requirement is met at the horizontal plane where the N-line is located, and it can also store dirt between the drain outlet 222 and the inlet 221. When the drain outlet 222 rotates downwards to below the axis of the inlet 221, the liquid level decreases, causing the dirt to be discharged from the drain outlet 222 and then from the box outlet 12 of the box body 1. The axis of the inlet 221 is located at the axis of the drain outlet 101. Figure 2 Above the Z-line in the middle, the rotation position is raised, and the drain pipe 2 rotates along the axis of the inlet 221 inside the box 1. This allows the drain outlet 222 to minimize the space occupied below the outlet 101 during the downward rotation, enabling the drain outlet 222 to rotate 180°. This facilitates the discharge of waste from the drain outlet 222 to the box outlet 12 of the box 1. During this process, the residue of waste in the drain pipe 2 is minimized, reducing the impact on rinsing.

[0054] like Figure 6 and Figure 9 As shown, in this current embodiment, in order to increase the height of the water cover and increase the potential energy of the water, the axis of the inlet 221 is set at 90° with the axis of the outlet 222, which can form a larger storage space between the inlet 221 and the outlet 222, thus forming a higher water cover. Similarly, the axis of the box inlet 11 and the axis of the box outlet 12 of the box body 1 are also set at 90°, and the box outlet 12 is located at the bottom of the box body 1. When the outlet 222 rotates down, the waste can be directly discharged from the box outlet 12.

[0055] In the current embodiment, the low point of the inlet 221 is collinear with the low point of the outlet 101, thereby further reducing the space occupied below the outlet 101 during rotation.

[0056] like Figure 4 and Figure 7 As shown, in order to facilitate the fixing of the drain pipe 2 and enable the drain pipe 2 to rotate within the box 1, in some embodiments, the drain pipe 2 includes a rotating cavity 21 and a pipe body 22. The rotating cavity 21 has a cavity opening 211, which is connected to the box inlet 11 of the box 1. The sewage inlet 221 is connected to the side of the rotating cavity 21 away from the cavity opening 211. Thus, the discharge outlet 101 is connected through the box inlet 11, allowing sewage to enter the sewage inlet 221 from the discharge outlet 101 through the box inlet 11. The rotating cavity 21 is sealed and connected to the box 1 by a sealing ring 5, and the axis of the sewage inlet 221 is collinear with the axis of the cavity opening 211. Thus, the rotating cavity 21 rotates around the axis of the cavity opening 211, thereby reducing the space required for the rotating cavity 21 to rotate.

[0057] In the current embodiment, the drain pipe 2 and the rotating cavity 21 are integrally formed, which facilitates molding and reduces manufacturing costs. In the current embodiment, the axis of the inlet 221 is collinear with the axis of the cavity opening 211. This arrangement allows for maximizing the size of the inlet 221 while maintaining the rotating position, up to the point where it matches the size of the cavity opening 211. This increase in the size of the inlet 221 does not increase the space occupied by the drain pipe 2 during rotation; it always rotates with the outer diameter of the rotating cavity 21 as its outer diameter. However, increasing the size of the inlet 221 allows waste to more easily enter the inlet 221 from the box inlet 11 of the box body 1 through the cavity opening 211. In the current embodiment, the orthographic projection of the box inlet 11 onto the inlet 221 is located within the inlet 221, facilitating waste entry. In addition, the diameter of the inlet 221 is larger than that of the outlet 222, and the two are connected by an arc-shaped surface so that the sewage can be discharged from the outlet 222 as soon as possible; for example, the diameter of the outlet 222 is not less than 60mm.

[0058] like Figure 5 As shown, in order to fix the box body 1 to the ceramic body 10, a fixing ring 16 is provided on the side of the box body 1 facing the ceramic body 10. The box inlet 11 of the box body 1 is located inside the fixing ring 16, and the fixing ring 16 is sleeved on the ceramic body 10. The outlet 101 of the ceramic body 10 is inserted into the fixing ring 16, so that dirt enters the inlet 221 through the box inlet 11. In the current embodiment, the axis of the box inlet 11 is collinear with the axis of the outlet 101, so that dirt enters the box inlet 11 of the box body 1 in a straight line through the outlet 101, reducing the resistance to dirt entry; of course, the box inlet 11 of the box body 1 and the outlet 101 of the ceramic body 10 can also have the same diameter. In another alternative embodiment, fixing flanges 17 can be provided on both the ceramic body 10 and the box body 1, so as to fix it by two opposing fixing flanges 17.

[0059] like Figures 7 to 9 As shown, in some embodiments, the diameter of the inlet 221 is equal to the diameter of the cavity 211. In this case, a ring edge 212 is circumferentially provided on the outer wall of the rotating cavity 21. The ring edge 212, the outer wall of the rotating cavity 21, and the inner wall of the box 1 form a sealing space for accommodating the sealing ring 5, so that the sealing ring 5 is located on the side facing the cavity 211, thereby achieving a dynamic seal. Figures 13 to 15As shown, in some alternative embodiments, the diameter of the inlet 221 is slightly smaller than the diameter of the cavity 211, so that a limiting step 213 is formed inside the rotating cavity 21. At this time, a plug ring 13 is provided inside the box 1, and the box inlet 11 of the box 1 is located inside the plug ring 13. The plug ring 13 is inserted into the cavity 211 of the rotating cavity 21, so that the plug ring 13, the inner wall of the rotating cavity 21 and the inner wall of the box 1 form a sealing space for accommodating the sealing ring 5, thereby achieving dynamic sealing.

[0060] like Figure 2 and Figure 4 As shown, in some embodiments, to facilitate the rotation of the drain pipe 2, the drain box is also provided with a drive component 6. The output end of the drive component 6 is connected to the drain pipe 2, specifically to the side of the pipe body 22 opposite to the inlet 221, so that the rotation of the drain pipe 2 is driven by the rotation of the output end of the drive component 6. In the current embodiment, the rotation axis of the output end of the drive component 6 is collinear with the axis of the inlet 221, thereby reducing the phenomenon of jamming. Exemplarily, the drive component 6 is a motor.

[0061] like Figure 4 and Figure 5 As shown, specifically, the box body 1 includes a lid 15 and a body 14. The body 14 has a mounting opening, and the lid 15 is fixed to the mounting opening. The lid 15 and the body 14 can be detachably connected by bolts, but are not limited to this connection. The box inlet 11 is located on the lid 15, and the box outlet 12 is located below the body 14, so that during the up-and-down rotation of the drain outlet 222, waste is discharged from the box outlet 12. In this embodiment, the size of the box outlet 12 of the box body 1 is larger than the size of the drain outlet 222, so that waste can pass smoothly from the drain outlet 222 through the box outlet 12 of the box body 1. The aforementioned sealing ring 5 is clamped between the ring edge 212 and the lid 15 or between the limiting step 213 and the lid 15. The driving component 6 is fixed to the outside of the body 14, and the output shaft of the driving component 6 passes through the body 14 and is connected to the tube body 22. The above-mentioned setup allows the drive component 6 and the drain pipe to be fixed to the box body 14 first, and then the box cover 15 to be fixed. This reduces the misalignment when fixing the drive component 6, lowers the probability of misalignment of the drive shaft of the drive component 6, and further reduces the occurrence of jamming.

[0062] like Figure 9 and Figure 10As shown, for example, a fixing structure 3 is provided on the pipe body 22. The fixing structure 3 is located on the side of the pipe body 22 away from the sewage inlet 221. The output end of the drive component 6 is connected to the pipe body 22 through the fixing structure 3. The fixing structure 3 can be, but is not limited to, a fixing hole or a fixing block. In the current embodiment, the fixing structure 3 is a fixing hole. The drive shaft of the drive component 6 is inserted into the fixing hole. In order to ensure stable rotation, a limiting tooth can be provided in the fixing hole to limit the engagement with the drive shaft.

[0063] Furthermore, during the sewage discharge process, the sewage pipe 2 only needs to rotate 180°. To prevent excessive rotation, the sewage box also has a blocking structure 4. When the pipe body 22 has rotated to its designated position, the blocking structure 4 can restrict its rotation, achieving the purpose of limiting the rotation. In the current embodiment, the blocking structure 4 includes a limiting ring 41, and a blocking block 42 is provided inside the limiting ring 41. Figure 6 As shown, the box body 14 is also provided with a mating block 43. The mating block 43 moves within the limiting ring 41, thereby being stopped by the blocking block 42.

[0064] It is understandable that the blocking structure 4 is not necessary, and the rotation of the sewage pipe 2 can also be restricted by setting the start and stop position of the drive component 6.

[0065] like Figure 8 and Figure 14 As shown, in some embodiments, an overflow notch 223 is provided at the drain outlet 222, such that the lowest point of the overflow notch 223 is lower than the drain outlet 222, thereby making the horizontal plane at the lowest point of the overflow notch 223 a water surface (e.g., Figure 8 (The horizontal plane where the M line is located), and when the drain outlet 222 is located above the water, the water surface is located at the low point of the overflow gap 223. When the toilet is flushed, the water level on the water surface rises rapidly, and the water level cannot drop instantly through the overflow gap 223. The water level will rise above the lowest point of the overflow gap 223 and below the end face of the drain outlet 222, thereby increasing the water level height and the potential energy of the water. Then, when the drain pipe 2 is flipped, more potential energy can be converted into the kinetic energy of the water, which can further improve the efficiency of sewage discharge and reduce the possibility of sewage buildup.

[0066] The overflow notch 223 is located on one side of the axis of the inlet 221. If the axis of the inlet 221 is set in the left-right direction, the overflow notch 223 is set in the direction in front of the axis of the inlet 221. Thus, when the pipe body 22 rotates towards the side where the overflow notch 223 is located (that is, when it rotates towards the axis of the inlet 221), dirt and water can fall through the overflow notch 223 during the rotation, thereby achieving the purpose of discharging dirt more quickly. For example, the overflow notch 223 is formed by the concavity of the end face of the outlet 222. The arc-shaped notch is relatively smooth, which can reduce the risk of dirt blockage compared with other types of notches such as rectangles or triangles.

[0067] like Figure 6 As shown, in some embodiments, at least the inner wall of the box body 1 on the side corresponding to the overflow notch 223 is an arc surface centered on the cavity 211, thereby reducing jamming during the rotation of the drain pipe 2. In the current embodiment, the radius of the arc surface is the same as the radius of rotation of the end face opposite to the overflow notch 223 of the drain port 222, so that the end face opposite to the overflow notch 223 of the drain port 222 fits against the arc surface during rotation. On the one hand, it maintains stability during rotation, and on the other hand, it allows the sewage to be discharged from the overflow notch 223 side as much as possible, reducing the difficulty of sewage discharge. At the same time, the sewage forms a smooth path on the arc surface, which also reduces the phenomenon of sewage sticking when discharged. In the current embodiment, in order to facilitate the forming of the box body 14, the longitudinal section of the box body 14 is circular, making it a symmetrical shape.

[0068] In other alternative embodiments, such as Figure 16 As shown, at least the inner wall of the box 1 on one side corresponding to the overflow notch 223 includes an arc segment 18 centered on the cavity opening 211 and a vertical segment 19. The vertical segment 19 is connected below the arc segment 18, and the box outlet 12 is formed at the end of the vertical segment 19 away from the arc segment 18. Thus, the arc segment 18 forms a smooth path, reducing the probability of the drain pipe 2 getting stuck during rotation. The vertical segment 19 increases the gap between the drain pipe and the inner wall of the box 1. During rotational drainage, the waste can be discharged through the vertical segment 19 to the box outlet 12, reducing the probability of waste getting stuck and reducing the risk of blockage. Of course, the inner wall on the other side of the box 1 can also be configured with the same shape.

[0069] This application also provides a toilet, which includes a ceramic body 10 and the aforementioned drain box. The drain box can be, but is not limited to, fixed to the ceramic body 10 by bolts or screws, so that the outlet 101 of the ceramic body 10 is connected to the inlet 11 of the drain box. Thus, through the drain box, the drain port 222 on the pipe body 22 can be rotated 180°, minimizing the residue of sewage in the drain pipe 2 and reducing the impact on flushing.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
