Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and more particularly to a drain box and toilet. Background Technology

[0002] A flip-top toilet is typically equipped with a drain pipe that connects to the ceramic body of the toilet. The drain pipe rotates to create a water cover, and then rotates again to lower the water level, thus flushing the toilet.

[0003] In related technologies, due to the limited space below the outlet of the ceramic body, it is difficult for the outlet of the drain pipe to rotate 180°, which can easily cause dirt residue during the draining process and affect the flushing function. Summary of the Invention

[0004] The purpose of this invention is to provide a drain box and toilet that solves the problem that the drain outlet of the drain pipe is difficult to rotate 180°, resulting in sewage residue.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The sewage box includes:

[0007] The box body has an inlet and an outlet, and can be fixed to a ceramic body so that the outlet of the ceramic body is connected to the inlet.

[0008] The sewage pipe has an inlet and an outlet. The axis of the outlet is parallel to the axis of the inlet. The inlet is connected to the box inlet. The axis of the inlet is located above the axis of the outlet. The sewage pipe rotates within the box along the axis of the inlet.

[0009] In some embodiments, the diameter of the sewage inlet is larger than the diameter of the sewage outlet;

[0010] And / or, the axis of the box inlet is collinear with the axis of the outlet;

[0011] And / or, the orthogonal projection of the box inlet onto the sewage inlet is located within the sewage inlet.

[0012] In some embodiments, the inlet and outlet are transitioned by a smooth arc surface.

[0013] In some embodiments, the drain pipe includes a rotating cavity and a pipe body. The rotating cavity is provided with an opening, which is connected to the inlet of the box body. The rotating cavity is sealed and connected to the box body. The inlet is connected to the side of the rotating cavity away from the opening, and the axis of the inlet is collinear with the axis of the opening.

[0014] In some embodiments, the diameter of the inlet is equal to the diameter of the cavity opening, and the outer wall of the rotating cavity is provided with a ring edge in the circumferential direction. The ring edge, the outer wall of the rotating cavity, and the inner wall of the box form a sealing space for accommodating the first sealing ring.

[0015] Alternatively, the diameter of the inlet is smaller than the diameter of the cavity opening, and a plug-in ring is provided inside the box. The plug-in ring is inserted into the cavity opening, and the plug-in ring, the inner wall of the rotating cavity, and the inner wall of the box form a sealing space for accommodating the first sealing ring.

[0016] In some embodiments, the pipe body is provided with a flange, the distance between the flange and the sewage inlet is not greater than the distance between the sewage outlet and the sewage inlet, and the flange clamps a second sealing ring with the inner wall of the box body.

[0017] In some embodiments, when the drain outlet is rotated to a position below the axis of the inlet, the axis of the drain outlet can be collinear with the axis of the outlet.

[0018] In some embodiments, the drain box further includes a drive component, the output end of which is connected to the drain pipe, and the rotation axis of the output end of the drive component is collinear with the axis of the drain inlet.

[0019] In some embodiments, the box body includes a box body and a box cover, the box body and the box cover are detachably connected, the box inlet is disposed on the box cover, the box outlet is disposed below the box body, the box cover can be connected to the ceramic body, and the driving component is fixed to the box body.

[0020] A toilet is also provided, which includes a ceramic body and a drain box as described above, the drain box being connected to the ceramic body.

[0021] The beneficial effects of this invention are:

[0022] The aforementioned drain box has its drain outlet axis parallel to the drain inlet axis. When the drain outlet is at a high position (above the drain inlet axis), there is a height difference between the drain outlet and the outlet, thus forming a water surface at the lowest point of the drain outlet. Since the drain inlet axis is above the outlet axis, when the drain pipe rotates along the drain inlet axis within the box, and when the drain outlet rotates from a high position to a low position (below the drain inlet axis), the liquid level decreases, allowing waste to be discharged from the drain outlet. Because the drain inlet connects to the box inlet and its axis is above the outlet axis, its rotation position is improved. This minimizes the space occupied below the outlet during the drain outlet's downward rotation, allowing the drain outlet to rotate 180°, minimizing waste residue in the drain pipe and reducing the impact on rinsing.

[0043] like Figures 1 to 8As 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 axis of the sewage outlet 222 is parallel to the axis of the sewage inlet 221. 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.

[0044] Using the above-mentioned drain box, the axis of drain outlet 222 ( Figure 1 The axis of the X-ray (mid-X-ray) and the axis of the sewage inlet 221 ( Figure 1 The discharge outlet 222 is set parallel to the Y-line. When the discharge outlet 222 is at a high position (the discharge outlet 222 is located above the axis of the inlet 221), there is a height difference between the discharge outlet 222 and the outlet 101, thus forming a water cover at the horizontal plane where the lowest point of the discharge outlet 222 is located (e.g., Figure 8 The horizontal plane where the M line is located); because the axis of the sewage inlet 221 is located on the axis of the outlet 101 ( Figure 1 Above the Z-line, when the drain pipe 2 rotates within the box 1 along the axis of the inlet 221, and when the drain outlet 222 rotates from a high position to a low position (when the drain outlet 222 is below the axis of the inlet 221), the liquid level decreases, and the waste can be discharged from the drain outlet 222. Since the inlet 221 is connected to the box inlet 11 and the axis of the inlet 221 is above the axis of the outlet 101, it increases the rotation position. Thus, during the downward rotation of the drain outlet 222, it can minimize the space occupied below the outlet 101, allowing the drain outlet 222 to rotate 180°, minimizing the residue of waste in the drain pipe 2, and reducing the impact on rinsing.

[0045] like Figure 7 and Figure 8As shown, in some embodiments, in order to facilitate fixing the drain pipe 2 and enable the drain pipe 2 to rotate within the box 1, 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, sewage enters the sewage inlet 221 from the outlet 101 through the box inlet 11 and is discharged from the sewage inlet 222. The rotating cavity 21 is sealed to the box 1 by a sealing ring, 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. In the current embodiment, the axis of the box inlet 11 is collinear with the axis of the outlet 101, thereby enabling dirt to enter the box inlet 11 from the outlet 101 as quickly as possible; for example, the box inlet 11 and the outlet 101 can be set to the same size.

[0046] 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 raising the rotational position, up to the point where it matches the size of the cavity opening 211. Increasing the size of the inlet 221 does not increase the space occupied by the drain pipe 2 during rotation; it always uses the outer diameter of the rotating cavity 21 as its rotational outer diameter. However, increasing the size of the inlet 221 allows for easier entry of waste. In the current embodiment, to facilitate the entry of waste from the outlet 101 into the box inlet 11, the projection of the box inlet 11 onto the inlet 221 is located within the inlet 221, facilitating waste entry. Furthermore, the diameter of the inlet 221 is larger than that of the outlet 222, and the two are connected by a smooth arc surface, forming a funnel-shaped receiving cavity. This allows waste to be discharged from the outlet 222 as quickly as possible, reducing the phenomenon of dirt accumulation. For example, the diameter of the outlet 222 is not less than 60mm. In the current embodiment, the lowest point of the inlet 221 is collinear with the lowest point of the outlet 101, thereby further reducing the space occupied below the outlet 101 during rotation.

[0047] like Figure 7As shown, in some embodiments, the diameter of the inlet 221 is equal to the diameter of the cavity opening 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 first sealing ring 4, so that the first sealing ring 4 is located on the side facing the cavity opening 211 to achieve dynamic sealing. In other alternative embodiments, the diameter of the inlet 221 is slightly smaller than the diameter of the cavity opening 211, so that a limiting step (not shown in the figure) is formed inside the rotating cavity 21. In this case, a plug-in ring can be provided inside the box 1. The box inlet 11 of the box 1 is located inside the plug-in ring. The plug-in ring is inserted into the cavity opening 211 of the rotating cavity 21, so that the plug-in ring, the inner wall of the rotating cavity 21, and the inner wall of the box 1 form a sealing space for accommodating the first sealing ring 4, thereby achieving dynamic sealing.

[0048] like Figure 4 and Figure 7 As shown, in addition, to further improve the sealing performance, a flange 23 is provided on the pipe body 22. The flange 23 and the inner wall of the box body 1 clamp the second sealing ring 5, thereby enhancing the sealing performance and preventing dirt from overflowing. In the current embodiment, the distance between the flange 23 and the sewage inlet 221 is not greater than the distance between the sewage outlet 222 and the sewage inlet 221, thereby preventing the sewage outlet 222 from being located between the second sealing ring 5 and the sewage inlet 221, and preventing the second sealing ring 5 from losing its function. In the current embodiment, the second sealing ring 5 is inserted into the flange 23.

[0049] like Figure 5 As shown, in some embodiments, in order to facilitate sewage discharge, when the sewage pipe 2 rotates along the axis of the sewage inlet 221, causing the sewage outlet 222 to rotate to the lowest position, that is, when the sewage outlet 222 rotates to below the axis of the sewage inlet 221, the axis of the sewage outlet 222 can be collinear with the axis of the outlet 101, so that the sewage can be quickly discharged from the outlet 101 through the sewage inlet 221 and the sewage outlet 222.

[0050] It is understandable that when the drain outlet 222 is in a high position (the drain outlet 222 is located above the axis of the inlet 221), the horizontal plane of the lowest point of the drain outlet 222 is a water surface. Therefore, when the toilet is flushed, the water level of the water surface rises rapidly. The water level cannot drop instantly through the drain outlet 222, and the water level will rise above the lowest point of the drain outlet 222, thereby increasing the potential energy of the water. Thus, when the drain outlet 222 rotates from a high position to a low position, it can convert more potential energy into kinetic energy, thereby improving the sewage discharge efficiency.

[0051] like Figure 1As 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. Exemplarily, the drive component 6 is a motor.

[0052] like Figure 5 As shown, specifically, the box body 1 includes a lid 14 and a body 13. In the current embodiment, the body 13 has a mounting opening, the lid 14 is inserted into the mounting opening, and a fixing edge is provided on the body 1. The fixing edge surrounds the outer wall of the body 1, thereby fixing the body 1 to the ceramic body 10 and pressing the lid 14 tightly. In other embodiments, the lid 14 can also be fixed by bolts for detachment.

[0053] In addition, the inner wall of the box body 13 is a smooth arc surface, which facilitates sewage discharge and reduces dirt accumulation.

[0054] In the current embodiment, the box inlet 11 is located on the box cover 14, and the box outlet 12 is located below the box body 13, so that during the up-and-down rotation of the drain port 222, the waste is discharged from the box outlet 12. In the current embodiment, the size of the box outlet 12 of the box body 1 is larger than the size of the drain port 222, so that the waste can pass smoothly from the drain port 222 through the box outlet 12 of the box body 1. The aforementioned first sealing ring 4 is clamped between the ring edge 212 and the box cover 14 or between the limiting step and the box cover 14. The driving component 6 is fixed to the outside of the box body 13, and the output end of the driving component 6 is sealed through the box body 13 and connected to the tube body 22. The above arrangement allows the driving component 6 to be fixed to the box body 13 first, and then the box cover 14 to be fixed, thereby reducing the misalignment when fixing the driving component 6, reducing the probability of misalignment of the driving axis of the driving component 6, and further reducing the occurrence of jamming.

[0055] like Figure 8 As 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 output end 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 output end.

[0056] Furthermore, during the sewage discharge process, the sewage pipe 2 only needs to rotate 180°. To prevent excessive rotation, the sewage box can also have a blocking structure (not shown). Once the pipe body 22 has rotated to its designated position, the blocking structure can restrict its rotation, thus achieving the purpose of limiting the rotation. For example, the blocking structure may include, but is not limited to, limiting rings or blocking blocks provided on the pipe body 22 and the box 1, so that the blocking blocks on the pipe body 22 and the box 1 mutually block and limit the rotation.

[0057] It is understandable that the blocking structure is not necessary, and the rotation of the drain pipe 2 can also be restricted by setting the start and stop position of the drive component 6.

[0058] 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.

[0059] 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.
