When the fixing member is in the locked state, the buckle is at least partially misaligned with the mounting port, and the buckle is engaged in the buckle channel. When the second connecting pipe moves towards the first connecting pipe, the overall length of the first connecting pipe and the second connecting pipe shortens. When the second connecting pipe moves away from the first connecting pipe, the overall length of the first connecting pipe and the second connecting pipe lengthens.

[0006] In one alternative embodiment, an annular groove is provided on the outer wall of the first connecting pipe; the drain pipe includes a first sealing ring disposed within the annular groove, the first sealing ring being located between the outer wall of the first connecting pipe and the inner wall of the second connecting pipe.

[0007] In one alternative embodiment, there are multiple annular grooves spaced apart from each other; there are multiple first sealing rings, each first sealing ring is disposed within one of the annular grooves, and the number of first sealing rings corresponds to the number of annular grooves.

[0008] In one alternative embodiment, the drain pipe includes a second sealing ring, which is fitted onto the outer wall of the first connecting pipe. The second sealing ring is located inside the fixing member, with one side of the second sealing ring abutting against the fixing member and the other side of the second sealing ring abutting against the second connecting pipe. The second sealing ring is located between the fixing member and the second connecting pipe.

[0009] In one alternative embodiment, the fastener is rotatable relative to the second connecting pipe to interchange between a first state and a second state; when the fastener is in the first state, the buckle is positioned opposite to the mounting port, and the buckle can enter or exit the buckle channel from the mounting port; when the fastener rotates to the second state by a preset angle, the buckle is at least partially misaligned with the mounting port, and the buckle engages within the buckle channel.

[0010] In one alternative embodiment, the latching channel is formed by a combination of a first latch and a second latch that are adjacent to each other and communicate with each other. The mounting port is connected to the second latch. When the fastener is in the first state, the latch is positioned opposite to the mounting port, and the latch can enter or exit the second latch from the mounting port. When the fastener is in the second state, the latch is at least partially misaligned with the mounting port, and the latch is at least partially engaged in the first latch.

[0011] In one alternative approach, the width of the first slot is smaller than the width of the second slot along the axial direction.

[0012] In one alternative embodiment, there are multiple snap-fit ​​channels, which are arranged around the inner wall of the fastener and are independent of each other and spaced apart; there are multiple snap-fits, which are arranged around the outer wall of the second connecting pipe and are spaced apart from each other, with one snap-fit ​​installed in one snap-fit ​​channel, and the number of snap-fits corresponds to the number of snap-fit ​​channels.

[0013] In one alternative embodiment, the first connecting pipe includes a vertical pipe and a first horizontal pipe connected to each other, the first connecting pipe being L-shaped, and the first horizontal pipe being connected to the second connecting pipe; the sewage pipe further includes a sealing sleeve, the sealing sleeve being disposed at the other end of the first connecting pipe, the sealing sleeve being located at the end of the vertical pipe opposite to the first horizontal pipe.

[0014] According to another aspect of this application, a toilet device is provided, including a toilet body and a drain pipe as described above, wherein the toilet body is provided with a drain channel and an outlet end communicating with the drain channel, and the outlet end is communicating with the drain pipe.

[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, this application embodiment includes a first connecting pipe, a second connecting pipe, and a fixing member. One end of the second connecting pipe is sleeved on one end of the first connecting pipe. The second connecting pipe can move axially relative to the first connecting pipe. The diameter of the second connecting pipe is larger than that of the first connecting pipe. The fixing member is sleeved on the outer wall of the second connecting pipe and is used to lock or release the second connecting pipe. The inner wall of the fixing member has a snap-fit ​​channel and an installation port communicating with the snap-fit ​​channel. The installation port is located at the edge of the fixing member. The outer wall of the second connecting pipe has a snap-fit ​​that can engage with the snap-fit ​​channel. When the fixing member is in the released state, the snap-fit ​​and the installation port are opposite each other, and the snap-fit ​​can enter or exit the snap-fit ​​channel from the installation port. When the fixing member is in the locked state, the snap-fit ​​and the installation port are at least partially misaligned, and the snap-fit ​​is engaged with the snap-fit ​​channel. The fastener channel on the fixing component engages with the fastener on the second connecting pipe, allowing the fixing component to lock or release the second connecting pipe. When the second connecting pipe moves closer to the first connecting pipe, the overall length of the first and second connecting pipes shortens; when the second connecting pipe moves away from the first connecting pipe, the overall length of the first and second connecting pipes lengthens. Compared to related technologies where the length of the drain pipe is fixed, in this embodiment, the user can flexibly adjust the overall length of the first and second connecting pipes according to actual needs when installing the toilet, allowing the overall length of the drain pipe to lengthen or shorten, so that the drain pipe can be connected to the drain pipe, ensuring smooth toilet installation and reducing installation errors.

[0018] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1The toilet device 1000 includes a toilet body 10 and a drain pipe 20. The toilet body 10 is provided with a drain channel 10a and a drain outlet 10b connected to the drain channel 10a. The drain outlet 10b is connected to the drain pipe 20, which is in turn connected to an external drain pipe, so that the liquid from the drain channel 10a flows from the drain outlet 10b through the drain pipe 20 to the external drain pipe.

[0022] For the aforementioned sewage pipe 20, such as Figures 2-4 As shown, the sewage pipe 20 includes a first connecting pipe 21, a second connecting pipe 22, and a fixing member 23. One end of the second connecting pipe 22 is sleeved on one end of the first connecting pipe 21. The second connecting pipe 22 can move axially upward relative to the first connecting pipe 21. The diameter of the second connecting pipe 22 is larger than the diameter of the first connecting pipe 21. The fixing member 23 is sleeved on the outer wall of the second connecting pipe 22 and is used to lock or loosen the second connecting pipe 22. When the second connecting pipe 22 moves closer to the first connecting pipe 21, the overall length of the first connecting pipe 21 and the second connecting pipe 22 shortens. When the second connecting pipe 22 moves away from the first connecting pipe 21, the overall length of the first connecting pipe 21 and the second connecting pipe 22 lengthens. Users can flexibly adjust the overall length of the first connecting pipe 21 and the second connecting pipe 22 according to actual needs to adjust the overall length of the sewage pipe 20. For example, when the length of the sewage pipe 20 is too short... When there is a distance between the drain pipe 20 and the sewer pipe, the user can first use the fixing piece 23 to loosen the second connecting pipe 22, and then move the second connecting pipe 22 away from the first connecting pipe 21 to extend the overall length of the drain pipe 20 until the length of the drain pipe 20 is sufficient for installation and connection with the sewer pipe. Finally, the fixing piece 23 is used to lock the second connecting pipe 22. When the length of the drain pipe 20 is too long, causing the drain pipe 20 to exceed the installation position of the sewer pipe, the user can first use the fixing piece 23 to loosen the second connecting pipe 22, and then move the second connecting pipe 22 closer to the first connecting pipe 21 to shorten the overall length of the drain pipe 20 until the length of the drain pipe 20 is sufficient for installation and connection with the sewer pipe. Finally, the fixing piece 23 is used to lock the second connecting pipe 22.

[0023] In some embodiments, please refer to the following: Figure 5The inner wall of the fastener 23 is provided with a snap-fit ​​channel 231 and an installation port 232 communicating with the snap-fit ​​channel 231. The installation port 232 is located at the edge of the fastener 23. The outer wall of the second connecting pipe 22 is provided with a snap-fit ​​22b, which can be snapped into the snap-fit ​​channel 231. When the fastener 23 is in the loose state, the snap-fit ​​22b is positioned opposite to the installation port 232, and the snap-fit ​​22b can enter or exit the snap-fit ​​channel 231 from the installation port 232. When the fastener 23 is in the locked state, the snap-fit ​​22b is at least partially misaligned with the installation port 232, and the snap-fit ​​22b is snapped into the snap-fit ​​channel 231. The snap-fit ​​channel 231 on the fastener 23 cooperates with the snap-fit ​​22b on the second connecting pipe 22 to lock or loosen the second connecting pipe 22.

[0024] In some embodiments, please refer to the following: Figure 5 The fixing member 23 can rotate relative to the second connecting pipe 22 to interchange between the first state and the second state. It should be noted that: the first state refers to the state in which the fixing member 23 is loosened from the second connecting pipe 22, at which time the second connecting pipe 22 can move axially relative to the first connecting pipe 21; the second state refers to the state in which the fixing member 23 is locked to the second connecting pipe 22, at which time the second connecting pipe 22 is relatively fixed to the first connecting pipe 21.

[0025] In some embodiments, when the fastener 23 is in the first state, the latch 22b is positioned opposite to the mounting port 232, and the latch 22b can enter or exit the latch channel 231 from the mounting port 232. When the fastener 23 is rotated to the second state by a preset angle, the latch 22b and the mounting port 232 are at least partially misaligned, and the latch 22b is engaged within the latch channel 231. Specifically, when the fastener 23 is in the first state, the latch 22b can be installed into the latch channel 231 from the mounting port 232, or the latch 22b can be disassembled from the mounting port 232 and exited from the latch channel 231. After the latch 22b is installed into the latch channel 231, the user can rotate the fastener 23 so that the latch 22b and the mounting port 232 are at least partially misaligned. At this time, the latch 22b cannot exit from the mounting port 232, and the latch 22b is engaged within the latch channel 231, thereby locking the second connecting pipe 22 by the fastener 23. It is understood that the angle of rotation required for the fastener 23 to switch between the first and second states is not specifically limited in this application, and users can set it according to their actual needs.

[0026] In some embodiments, the latching channel 231 is formed by a combination of a first latching slot 231a and a second latching slot 231b that are adjacent and interconnected. The mounting opening 232 communicates with the second latching slot. When the fastener 23 is in the first state, the latch 22b is positioned opposite to the mounting opening 232, and the latch 22b can enter or exit the second latching slot from the mounting opening 232. When the fastener 23 is in the second state, the latch 22b is at least partially misaligned with the mounting opening 232, and the latch 22b is at least partially engaged in the first latching slot. The user can rotate the fastener 23 to interchange the positions of the latch 22b in the first and second latching slots, thereby placing the fastener 23 in different states.

[0027] In some embodiments, the width of the first slot is smaller than the width of the second slot along the axial direction. This arrangement provides more space for the second slot to allow the buckle 22b to enter, reducing assembly difficulty and facilitating the insertion of the buckle 22b from the mounting port 232 into the second slot. The buckle 22b then engages with the first slot. In some embodiments, an interference fit between the buckle 22b and the first slot allows for a more stable engagement of the buckle 22b within the buckle channel 231.

[0028] In some embodiments, there are multiple snap-fit ​​channels 231, which are arranged around the inner wall of the fastener 23. The multiple snap-fit ​​channels 231 are independent of each other and spaced apart. There are multiple snap-fits 22b, which are arranged around the outer wall of the second connecting pipe 22. The multiple snap-fits 22b are spaced apart from each other. One snap-fit ​​22b is installed in one snap-fit ​​channel 231, and the number of snap-fits 22b corresponds to the number of snap-fit ​​channels 231. The arrangement of multiple snap-fit ​​channels 231 and multiple snap-fits 22b can make the connection between the fastener 23 and the second connecting pipe 22 more stable. At the same time, it can make the locking force of the fastener 23 on the second connecting pipe 22 more uniform.

[0029] It should be noted that in this application, the fixing member 23 has a ring-shaped structure. In other embodiments, the fixing member 23 may be a clamp structure, which cooperates with the connecting screw to lock or loosen the second connecting pipe 22. It is understood that, in addition to the above-mentioned cooperation of the buckle 22b and the buckle channel 231, the fixing member 23 may also adopt a threaded connection. For example, the inner wall of the fixing member 23 is provided with an internal thread, and the outer wall of the second connecting pipe 22 is provided with an external thread. The internal thread of the fixing member 23 is threaded to the external thread to realize the connection between the fixing member 23 and the second connecting pipe 22.

[0030] In some embodiments, please refer to Figures 2-4The first connecting pipe 21 includes a vertical pipe 211 and a first horizontal pipe 212 connected to each other. The first connecting pipe 21 is L-shaped. The first horizontal pipe 212 is connected to the second connecting pipe 22. The vertical pipe 211 is connected to the outlet end 10b of the drainage channel 10a. The liquid in the drainage channel 10a flows through the vertical pipe 211 and the first horizontal pipe 212 to the second connecting pipe 22.

[0031] In some embodiments, the second connecting pipe 22 includes a second horizontal pipe 221 and a bent pipe 222 connected to each other. One end of the second horizontal pipe 221 away from the bent pipe 222 is connected to the first horizontal pipe 212, and the bent pipe 222 is connected to an external drain pipe.

[0032] In some embodiments, please refer to the following: Figure 6 The number of first connecting pipes 21 can be multiple. Adjacent first connecting pipes 21 can be connected by fasteners 23 or other connectors. Adjacent first connecting pipes 21 can move relative to each other to adjust their axial length.

[0033] It should be noted that: Please refer to the following as well. Figure 7 and Figure 8 In actual installation, the toilet device is usually installed close to the wall. Users usually define the distance D between the side of the toilet device closest to the wall and the middle of the bend pipe 222 in the horizontal direction. In related technologies, this distance D is usually fixed. However, in this application, since the second connecting pipe 22 can move axially upward relative to the first connecting pipe 21, the distance D can be increased or decreased accordingly. The distance D can be adjusted to 305mm or 400mm or other values. Users can adjust the distance D specifically between 305mm, 400mm or other values ​​according to actual needs. This application does not make specific limitations.

[0034] In some embodiments, please refer to Figure 2 , Figure 9 and Figure 10The drain pipe 20 also includes a first sealing ring 24, a second sealing ring 25, and a sealing sleeve 26. The first sealing ring 24 is located between the outer wall of the first connecting pipe 21 and the inner wall of the second connecting pipe 22 to seal the gap between the first connecting pipe 21 and the second connecting pipe 22. The second sealing ring 25 is used to seal the gap between the fixing member 23 and the second connecting pipe 22. The sealing sleeve 26 is disposed at the other end of the first connecting pipe 21, which is the end of the first connecting pipe 21 facing away from the second connecting pipe 22. The other end of the first connecting pipe 21 is connected to the outlet end 10b of the drain channel 10a. The sealing sleeve 26 is used to seal the gap between the first connecting pipe 21 and the outlet end 10b to reduce leakage. In some embodiments, the sealing sleeve 26 is disposed at the other end of the first connecting pipe 21, and the sealing sleeve 26 is located at the end of the vertical pipe 211 facing away from the first horizontal pipe 212. The sealing sleeve 26 can reduce leakage between the outlet end 10b and the vertical pipe 211.

[0035] In some embodiments, please refer to the following: Figure 5 The fastener 23 extends radially along the side near the first connecting pipe 21 with a limiting stop 23a. The limiting stop 23a abuts against the second sealing ring 25 and is used to restrict the second sealing ring 25 from moving axially upward.

[0036] In some embodiments, please refer to the following: Figure 11 The second connecting pipe 22 is provided with an inclined pressure surface 22a at one end near the first connecting pipe 21. The inclined pressure surface 22a faces the first connecting pipe 21 and abuts against the second sealing ring 25. When the fixing member 23 is in the locked state, the inclined pressure surface 22a presses the second sealing ring 25 radially upward, increasing the friction between the second sealing ring 25 and the first connecting pipe 21. At the same time, the second sealing ring 25 provides a rebound force to the second connecting pipe 22, so that the second connecting pipe 22 and the fixing member 23 are locked together, thereby further improving the locking force between the fixing member 23 and the second connecting pipe 22.

[0037] In some embodiments, an annular groove 21a is provided on the outer wall of the first connecting pipe 21, and the first sealing ring 24 is disposed in the annular groove 21a. The annular groove 21a can reduce the direct exposure of the first sealing ring 24 on the outer wall of the first connecting pipe 21. At the same time, the annular groove 21a can reduce the displacement or detachment of the first sealing ring 24, so that the first sealing ring 24 is more stably installed on the outer wall of the first connecting pipe 21.

[0038] In some embodiments, there are multiple annular grooves 21a, which are spaced apart. There are multiple first sealing rings 24, each of which is disposed within an annular groove 21a. The number of first sealing rings 24 corresponds to the number of annular grooves 21a. By using multiple annular grooves 21a in conjunction with multiple first sealing rings 24, a multi-layer seal is achieved, which further improves the sealing performance of the gap between the first connecting pipe 21 and the second connecting pipe 22 and reduces the occurrence of leakage.

[0039] In some embodiments, the second sealing ring 25 is sleeved on the outer wall of the first connecting pipe 21. The second sealing ring 25 is located inside the fixing member 23. One side of the second sealing ring 25 abuts against the fixing member 23, and the other side of the second sealing ring 25 abuts against the second connecting pipe 22. The second sealing ring 25 is located between the fixing member 23 and the second connecting pipe 22. The second sealing ring 25 is used to seal the gap between the fixing member 23 and the second connecting pipe 22 to reduce the leakage of liquid in the drain pipe 20 from the gap between the fixing member 23 and the second connecting pipe 22, thereby reducing the occurrence of leakage.

[0040] In this embodiment of the application, a first connecting pipe 21, a second connecting pipe 22, and a fixing member 23 are provided. In this design, one end of the second connecting pipe 22 is sleeved on one end of the first connecting pipe 21. The second connecting pipe 22 can move axially relative to the first connecting pipe 21. The diameter of the second connecting pipe 22 is larger than that of the first connecting pipe 21. A fixing member 23 is sleeved on the outer wall of the second connecting pipe 22 and is used to lock or release the second connecting pipe 22. The inner wall of the fixing member 23 is provided with a snap-fit ​​channel 231 and an installation port 232 communicating with the snap-fit ​​channel. The installation port 232 is located at the edge of the fixing member 23. A snap-fit ​​22b is provided on the outer wall of the second connecting pipe 22. The snap-fit ​​22b can be snapped into the snap-fit ​​channel 231. When the fixing member 23 is in the released state, the snap-fit ​​22b is opposite to the installation port 232 and can enter or exit the snap-fit ​​channel 231 from the installation port 232. When the fixing member 23 is in the locked state, the snap-fit ​​22b and the installation port 232 are at least partially misaligned. The buckle 22b engages within the buckle channel 231. The buckle channel 231 on the fixing member 23 cooperates with the buckle 22b on the second connecting pipe 22, enabling the fixing member 23 to lock or release the second connecting pipe 22. When the second connecting pipe 22 moves towards the first connecting pipe 21, the overall length of the first connecting pipe 21 and the second connecting pipe 22 shortens. When the second connecting pipe 22 moves away from the first connecting pipe 21, the overall length of the first connecting pipe 21 and the second connecting pipe 22 lengthens. Compared to related technologies where the length of the drain pipe 20 is fixed, in this embodiment, when installing the toilet, the user can flexibly adjust the overall length of the first connecting pipe 21 and the second connecting pipe 22 according to actual needs, so that the overall length of the drain pipe 20 can be lengthened or shortened, allowing the drain pipe 20 to be connected to the drain pipe, ensuring smooth installation of the toilet and reducing installation errors.

[0041] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
