Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary ware technology, and in particular to a sewage pipe and a toilet. Background Technology
[0002] Flip-top toilets typically have a drain pipe connected to the ceramic body of the toilet bowl. 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, the sewage pipe has a pipe body and a rotating cavity. The pipe body is connected to the ceramic body through the rotating cavity. However, the pipe body is eccentrically set on the rotating cavity. With the above arrangement, the inlet size of the sewage pipe is small and the water storage in the sewage pipe is small, which makes it difficult for sewage to enter the sewage inlet smoothly and easily causes the problem of poor sewage discharge. Utility Model Content
[0004] The purpose of this utility model is to provide a sewage pipe and toilet to solve the problem of poor sewage discharge.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] Sewage pipes, which include:
[0007] A rotating cavity, wherein the rotating cavity is provided with an opening;
[0008] The pipe body is provided with a sewage inlet and a sewage outlet. The diameter of the sewage inlet is larger than the diameter of the sewage outlet. The sewage inlet is connected to the side of the rotating cavity away from the cavity opening. The sewage inlet and the cavity opening are coaxially arranged.
[0009] The axis of the drain outlet is parallel to the axis of the cavity opening; or, the angle between the axis of the drain outlet and the axis of the cavity opening is α, where 0° < α ≤ 90°.
[0010] In some embodiments, the inlet and outlet are transitioned by a smooth arc surface.
[0011] In some embodiments, the diameter of the inlet is equal to the diameter of the cavity opening, and the outer side wall of the rotating cavity is provided with a circumferential edge;
[0012] Alternatively, the diameter of the sewage inlet is smaller than the diameter of the cavity opening.
[0013] In some embodiments, when the axis of the drain outlet is parallel to the axis of the cavity, the outer wall of the pipe body is provided with a flange in the circumferential direction.
[0014] In some embodiments, when the axis of the drain outlet and the axis of the cavity have an angle α, an overflow notch is provided at the drain outlet.
[0015] In some embodiments, the overflow notch is located on one side of the axis of the cavity.
[0016] In some embodiments, the overflow notch is formed by a recess in the end face of the drain outlet.
[0017] In some embodiments, a fixing structure is provided on the side of the tube body opposite to the cavity opening, and the fixing structure can be connected to the output end of an external driving component.
[0018] In some embodiments, a blocking structure is provided on the side of the tube body away from the cavity opening to prevent the tube body from rotating excessively.
[0019] A toilet is also provided, comprising a ceramic body, wherein the toilet employs a drain pipe as described above, and the rotating cavity is adapted to the ceramic body such that the cavity opening is connected to the outlet of the ceramic body.
[0020] The beneficial effects of this utility model are:
[0021] By aligning the inlet and outlet coaxially, the size of the inlet can be maximized, allowing for smoother entry of waste. The outlet axis is parallel to or at an angle to the outlet axis, with the inlet diameter larger than the outlet diameter. When the outlet is positioned above the outlet axis, a larger storage space is created between the inlet and outlet, resulting in a higher water surface that can hold more waste and water, thus facilitating smoother drainage and reducing the likelihood of blockages.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] Figures 1 to 10 As shown, this application provides a sewage pipe, which includes a rotating cavity 1 and a pipe body 2. The rotating cavity 1 has an opening 11 and is rotatably connected to a ceramic body so that the opening 11 communicates with the outlet of the ceramic body. The pipe body 2 has an inlet 21 and an outlet 22. The diameter of the inlet 21 is larger than the diameter of the outlet 22. The inlet 21 is connected to the side of the rotating cavity 1 away from the opening 11. The inlet 21 and the opening 11 are coaxially arranged. The axis of the outlet 22 is parallel to the axis of the opening 11; or, the angle between the axis of the outlet 22 and the axis of the opening 11 is α, where 0° < α ≤ 90°.
[0042] By coaxially aligning the inlet 21 with the cavity opening 11, the size of the inlet 21 can be maximized, allowing for smoother entry of waste into the inlet 21; while the axis of the outlet 22 ( Figure 3 , Figure 7 as well as Figure 10 The X-ray in the cavity 11 and the axis of the cavity 11 ( Figure 3 , Figure 7 as well as Figure 10 The inlet 21 is parallel to the Y-line in the cavity or is set at the angle mentioned above, and the diameter of the inlet 21 is larger than the diameter of the outlet 22. When the outlet 22 is rotated to the axis above the cavity 11, a larger storage space can be formed between the inlet 21 and the outlet 22, and a higher water cover can be formed, which can accommodate more dirt and water, making the sewage discharge smoother and reducing the possibility of blockage.
[0043] Furthermore, such as Figures 8 to 10As shown, in one embodiment, the axis of the drain outlet 22 is parallel to the axis of the cavity 11. When the drain outlet 22 rotates above the axis of the cavity 11, the horizontal plane at the lowest point of the drain outlet 22 is the plane where the water cover is located (e.g., Figure 6 and Figure 10 The N-line is located on the horizontal plane. The storage space between the inlet 21 and the outlet 22 stores the waste. When the outlet 22 rotates downward to below the axis of the cavity 11, the waste is discharged horizontally along the axis of the outlet 22, which can also reduce the possibility of dirt sticking.
[0044] In another embodiment, such as Figures 1 to 7 As shown, in order to increase the height of the water cover and increase the potential energy of the water, a is 90°. At this time, the axis of the drain outlet 22 is perpendicular to the axis of the cavity 11. When the drain outlet 22 is above the axis of the cavity 11, the horizontal plane where the lowest point of the drain outlet 22 is located is the plane where the water cover is located. When the drain outlet 22 rotates downward to below the axis of the cavity 11, the dirt is directly discharged from the drain outlet 22.
[0045] In some embodiments, the tube body 2 and the rotating cavity 1 are integrally formed, thereby reducing the need for additional sealing operations at the connection point; and the integral forming also facilitates manufacturing and saves costs.
[0046] In some embodiments, the inlet 21 and outlet 22 are transitioned by a smooth arc surface, such as Figure 1 As shown, when a is 90°, the pipe body 2 is set as a smooth 90° bend; and as... Figure 8 As shown, when the axis of the drain outlet 22 is parallel to the axis of the cavity 11, the pipe body 2 resembles a smooth funnel shape. This allows waste to be smoothly discharged from the drain outlet 22 when the drain pipe rotates to discharge waste, reducing the possibility of waste accumulating inside the pipe body 2. To facilitate the rotation of the rotating cavity 1 and ensure smooth waste discharge, in this embodiment, the cavity 11, the inlet 21, and the drain outlet 22 are all round. To further facilitate waste discharge and reduce blockage at the drain outlet 22, the diameter of the drain outlet 22 is not less than 60 mm.
[0047] To facilitate the rotation of cavity 1 when connecting to the ceramic body, the cavity opening 11 is sealed; in some embodiments, such as Figure 3 As shown, when the diameter of the inlet 21 is equal to the diameter of the cavity 11, a ring edge 12 is provided circumferentially on the outer wall of the rotating cavity 1. This allows the sealing ring to be fitted onto the outer circumference of the rotating cavity 1 during installation, and the ring edge 12 to limit its movement. During rotational connection, the ring edge 12 presses the sealing ring against the ceramic body, forming a seal. In other embodiments, such as... Figure 5 and Figure 7As shown, when the diameter of the inlet 21 is smaller than the diameter of the cavity 11, a limiting step 13 will be formed inside the rotating cavity 1. At this time, the sealing ring can be directly fixed on the limiting step 13. In other words, when the diameter of the inlet 21 is smaller than the diameter of the cavity 11, the sealing ring can be directly fixed inside the rotating cavity 1 without the need to set an additional ring edge 12.
[0048] like Figure 9 As shown, when the axis of the drain outlet 22 is parallel to the axis of the cavity 11, a flange 24 is provided on the outer wall of the pipe body 2. The distance between the flange 24 and the drain inlet 21 is not greater than the distance between the drain outlet 22 and the drain inlet 21, so that a sealing ring can be inserted on the flange 24 to further improve the sealing performance.
[0049] like Figure 2 and Figure 6 As shown, in some embodiments, when the axis of the drain outlet 22 forms an angle α with the axis of the cavity 11, an overflow notch 23 is also provided at the drain outlet 22. The low point of the overflow notch 23 is lower than the drain outlet 22, so that the horizontal plane where the low point of the overflow notch 23 is located is the water surface (e.g., Figure 6 (The horizontal plane where the M line is located). When the drain outlet 22 is above the drain outlet of the ceramic body and is in a water-storage state, the water surface is located at the low point of the overflow outlet. When the toilet is flushed, the water level of the water surface rises rapidly, and the water level cannot drop instantly through the overflow gap 23. The water level will rise above the lowest point of the overflow gap 23 and below the end face of the drain outlet 22, thereby increasing the water level height and increasing the potential energy of the water. Then, when the drain pipe is flipped, more potential energy can be converted into the kinetic energy of the water, which can further improve the discharge efficiency of sewage and reduce the possibility of sewage sticking.
[0050] like Figure 1 and Figure 2 As shown, taking 'a' as 90° as an example, the overflow notch 23 is located on one side of the axis of the cavity 11. For example, if the axis of the cavity 11 extends in the left-right direction, the overflow notch 23 is located on one side of the axis of the cavity 11 in the front-back direction. Thus, when the cavity 11 rotates towards the side where the overflow notch 23 is located, dirt and water can fall through the overflow notch 23 during the rotation, thereby achieving the purpose of discharging dirt more quickly and obtaining greater kinetic energy. Exemplarily, the overflow notch 23 is formed by the concave end face of the drain 22. The arc-shaped notch is relatively smooth, which can reduce the risk of dirt blockage compared to other types of notches such as rectangles or triangles.
[0051] It is understandable that when the axis of the drain outlet 22 is parallel to the axis of the cavity 11, if the drain outlet 22 is located above the outlet of the ceramic body and is in a water-filled state, the horizontal plane of the lowest point of the drain outlet 22 is a water surface. Therefore, when the toilet is flushed, the water level of the water surface rises rapidly, and the water level cannot drop instantly through the drain outlet 22. The water level will rise above the lowest point of the drain outlet 22, thereby increasing the potential energy of the water. In turn, more potential energy can be converted into kinetic energy during rotation, thereby improving the efficiency of waste discharge.
[0052] like Figure 4 and Figure 9 As shown, in some embodiments, a fixing structure 3 is provided on the side of the pipe body 2 away from the cavity opening 11. The fixing structure 3 can be connected to the output end of an external driving component, thereby allowing the drain pipe to rotate and the height of the water cover to be changed by connecting the driving structure. The fixing structure 3 can be, but is not limited to, a fixing hole or a fixing block, so that it can be connected to the output end of the driving component by means including but not limited to plugging or snapping.
[0053] In some embodiments, a blocking structure 4 is provided on the side of the tube body 2 away from the cavity opening 11 to prevent the tube body 2 from rotating excessively. Once the tube body 2 has rotated to its current position, the blocking structure 4, in conjunction with external components, can limit its rotation, thereby achieving the purpose of limiting the position. Exemplarily, the blocking structure 4 may include, but is not limited to, an arc-shaped groove or a blocking block, etc. The specific type is not limited and can be set according to the required cooperating structure.
[0054] It is understandable that the blocking structure 4 is not necessary, and the rotation of the sewage pipe can also be restricted by setting the driving angle of the driving component.
[0055] This application also provides a toilet, which includes a ceramic body and the aforementioned drain pipe. The drain pipe is rotatably connected to the ceramic body, thereby connecting the cavity 11 with the outlet of the ceramic body, thus making the sewage discharge smoother.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. 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 this utility model should be included within the protection scope of the claims of this utility model.
