[0029] Embodiment 1

[0030] In order to solve the problem in the prior art that a sewage pipe used in conjunction with a siphon-based toilet will generate loud noise when liquid flows in the sewage pipe, the present application provides a sewage pipe that achieves the purpose of noise reduction by reducing the vibration generated during the flushing process.

[0031] A sewage pipe, see Figures 1 to 3The sewage pipe is arranged outside the toilet body and is used to communicate with the liquid outlet end of the toilet body. The sewage pipe includes a pipe body 1 and an outer shell 2. The pipe body 1 has at least an elastic inner wall. The outer shell 2 includes at least a first shell 21 and a second shell 22 that are detachably connected. The first shell 21 and the second shell 22 cooperate to form an installation channel 23. The pipe body 1 is arranged inside the safety channel. At least a portion of the outer surface of the pipe body 1 contacts the first shell 21, and at least another portion of the outer surface of the pipe body contacts the second shell 22.

[0032] Compared with the hard material of the sewage pipe of the traditional toilet, the pipe body 1 in this embodiment has an elastic inner wall, which can play a certain buffering role, thereby reducing the vibration generated during the drainage process, and further reducing the noise generated during the drainage process. Since the pipe body 1 has an elastic inner wall, it may be deformed or shaken by the impact of water during the flushing process. In order to avoid this deformation or shaking, a shell 2 is added to the outside of the pipe body 1, and the pipe body 1 is limited by the shell 2 to avoid deformation or shaking of the pipe body 1. At the same time, the sewage pipe can also be fixed by using the shell 2 of the pipe body 1 as a fixing member.

[0033] Preferably, the outer shell 2 is made of plastic material. The outer shell 2 made of plastic material can be easily processed into a structure matching with the tube body 1, which is beneficial to ensure the overall adaptation accuracy and has good effects of buffering and offsetting external forces.

[0034] Furthermore, the tube body 1 is made of elastic material.

[0035] When the pipe body 1 is made of elastic material, the whole pipe body 1 is elastic, which is conducive to improving the noise reduction effect of the pipe body 1. When the entire pipe body 1 is made of elastic material, the pipe body 1 can be made of rubber material, so that the pipe body 1 can be integrally formed during the processing, and can present a complex structure with uniform wall thickness. Compared with the ceramic pipe of the toilet, it has the advantage of high precision, and the stability of the flushing function can be guaranteed due to the high precision.

[0036] Furthermore, the outer surface of the pipe body 1 abuts against the inner wall of the installation channel 23. The outer surface of the pipe body 1 and the inner wall of the installation channel 23 adopt a surface-to-surface abutment structure, which is conducive to improving the installation stability of the pipe body 1; at the same time, there is no gap between the pipe body 1 and the inner wall of the installation channel 23, which is conducive to further achieving noise reduction.

[0037] This embodiment adopts a structural setting in which the tube body 1 abuts against the inner wall surface of the installation channel 23. In this way, during the toilet flushing process, the impact force generated by the liquid on the inner wall of the tube body 1 can be directly offset by the supporting force of the shell, and the tube body 1 will not be deformed, thereby increasing the stability of the tube body 1.

[0038] In this embodiment, the first shell 21 includes a mounting portion 211 and a fixing portion 212 which are connected to each other. The mounting portion 211 is symmetrically arranged with the second shell 22. The mounting portion 211 and the second shell 22 cooperate to form a first sub-channel 231. The fixing portion 212 has a second sub-channel 232 which is connected to the first sub-channel 231. The first sub-channel 231 and the second sub-channel 232 form a mounting channel 23.

[0039] Specifically, the symmetrically arranged mounting portion 211 and the second shell 22 respectively have a receiving groove. During the installation of the tube body 1, a portion of the tube body 1 extends into the interior of the second sub-channel 232 and is installed into the interior of the receiving groove of the mounting portion 211, thereby completing the installation between the tube body 1 and the first shell 21; then the second shell 22 is connected and fixed to the mounting portion 211, so that the portion of the tube body 1 exposed outside the mounting portion 211 is accommodated inside the receiving groove of the second shell 22, thereby completing the installation of the tube body 1.

[0040] Furthermore, the mounting portion 211 and the fixing portion 212 are an integrally formed structure.

[0041] Furthermore, in this embodiment, the second shell 22 may be detachably connected to the mounting portion 211; the second shell 22 and the fixing portion 212 may also be detachably connected; of course, the second shell 22 may also be detachably connected to both the mounting portion 211 and the fixing portion 212.

[0042] By detachably connecting the first shell 21 and the second shell 22, the installation and disassembly of the shell as a whole are facilitated, and the installation of the tube body 1 and the shell is facilitated during the installation process. At the same time, during the installation and disassembly of the tube body 1, the detachable connection between the first shell 21 and the second shell 22 also facilitates the installation and disassembly of the tube body 1.

[0043] In this embodiment, the specific means of detachable connection between the first shell 21 and the second shell 22 can be snap connection or bonding or connection through fasteners, and the fasteners can be structural parts such as bolts.

[0044] The first shell 21 and the second shell 22 can be connected in different ways to achieve the connection and fixation between the first shell 21 and the second shell 22 .

[0045] Further, see Figures 1 to 3 Along the extension direction of the tube body 1 , the tube body 1 includes a bent tube segment 11 and a straight tube segment 12 arranged in sequence. The bent tube segment 11 is arranged inside the first sub-channel 231 , and the straight tube segment 12 is arranged inside the second sub-channel 232 .

[0046] Among them, the straight pipe section 12 is a linearly extended pipe section, so that in the process of installing the pipe body 1 into the interior of the outer shell 2, the straight pipe section 12 can be extended into the interior of the first sub-channel 231 for pre-fixation, thereby improving the stability and convenience of the installation, and thus helping to improve the installation efficiency.

[0047] Furthermore, the bent pipe segment 11 includes a first pipe segment 111 and a second pipe segment 112. The first pipe segment 111 is connected to the straight pipe segment 12. The second pipe segment 112 is arranged at an end of the first pipe segment 111 away from the straight pipe segment 12. The outer diameter of the second pipe segment 112 is larger than the outer diameter of the first pipe segment 111, so as to form a radially extending first abutting surface 14 at the outer surface of the connecting area of ​​the first pipe segment 111 and the second pipe segment 112. The first shell 21 and the second shell 22 cooperate to form a second abutting surface 24 that abuts and fits with the first abutting surface 14.

[0048] Among them, the first abutting surface 14 and the second abutting surface are both annular surface structures. In this embodiment, the first abutting surface 14 and the second abutting surface 24 are abutted to achieve a surface-to-surface structure, so that when the liquid impacts the inner wall of the tube body 1, the tube body 1 will not be displaced inside the shell 2 along the direction of liquid flow. The structural arrangement of the first abutting surface 14 and the second abutting surface 24 in this embodiment further enhances the stability and connection strength of the connection between the tube body 1 and the shell.

[0049] Furthermore, the inner diameter of the second pipe segment 112 is greater than the inner diameter of the first pipe segment 111, so as to form a radially extending third abutment surface 15 at the inner surface of the connection area between the first pipe segment 111 and the second pipe segment 112, and the second abutment surface 24 is parallel to the third abutment surface 15, and the third abutment surface 15 is used to abut with the pipe structure connected to the second pipe segment 112.

[0050] It should be noted that when the external pipe structure of the sewage pipe needs to be connected to the pipe body 1 to form a channel for liquid circulation, the pipe structure can be installed by abutting against the third abutment surface 15. The setting of the third abutment surface 15 is conducive to improving the convenience and stability of the connection. At the same time, the radially arranged third abutment surface 15 also facilitates improving the sealing of the connection.

[0051] In this embodiment, the tube body 1 is divided into different tube sections, so that during the processing and matching of the tube body 1 and the shell, when it is necessary to change and adjust the local features, the relative position of the shell 2 or the tube body 1 can be easily found through the fine division of the tube body 1, thereby facilitating changes and adjustments.

[0052] Furthermore, if Figure 2As shown, an annular protrusion 13 is provided on the outer surface of the straight pipe section 12 , an annular limiting groove 25 is provided inside the first sub-channel 231 , and the protrusion 13 is arranged inside the limiting groove 25 .

[0053] The annular protrusion 13 cooperates with the limiting groove 25 to limit the tube body 1 by the shell 2, thereby increasing the stability of the tube body 1 after installation, which is beneficial to improving the fixing and supporting effect of the shell 2 on the tube body 1.

[0054] In this embodiment, the number of the protrusions 13 may be one or more. When there are multiple protrusions 13 , the multiple protrusions 13 are spaced apart along the axial direction of the straight pipe section 12 .

[0055] Embodiment 2

[0056] This embodiment provides a toilet device, which includes a toilet body and the sewage pipe in the first embodiment. The toilet body has a liquid outlet end, and the liquid outlet end is connected to the sewage pipe.

[0057] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0058] 1. Since the pipe body 1 has an elastic inner wall, the elastic inner wall can play a certain buffering role, thereby reducing the vibration generated during the drainage process, and further reducing the noise generated during the drainage process.

[0059] 2. Add a shell 2 outside the tube body 1 to limit the tube body 1 through the shell 2 to prevent the tube body 1 from being deformed or shaken.

[0060] 3. When the pipe body 1 is made of elastic material, the entire pipe body 1 has a certain elasticity, and the elastic inner wall is only a part of the pipe body 1, so as to achieve the noise reduction effect of the pipe body 1. When the entire pipe body 1 is made of elastic material, the pipe body 1 can be made of rubber material, so that the pipe body 1 can be integrally formed during the processing, and can present a complex structure with uniform wall thickness. Compared with the ceramic pipe of the toilet, it has the advantage of high precision, and the stability of the flushing function can be guaranteed due to the high precision.

[0061] 4. The annular protrusion 13 cooperates with the limiting groove 25 to limit the tube body 1 by the shell 2, thereby increasing the stability of the tube body 1 after installation, which is beneficial to improving the fixing and supporting effect of the shell 2 on the tube body 1.
