[0044] Please see Figures 1-10 As shown, this utility model discloses a toilet drain connection accessory, adapted to toilets with a drain outlet 201 on the rear side, used to connect the drain outlet 201 to a drain pipe on the ground. It includes a drain inlet 1, a drain guide 2, and a drain outlet 3 connected in sequence. The drain inlet 1 connects to the drain outlet 201, and the drain outlet 3 extends downwards and connects to the drain pipe, thus converting a wall-mounted toilet into a floor-mounted one without requiring any modification to the existing ground pipes, significantly reducing construction difficulty and cost. The drain guide 2 includes a cuttable section 21 and a fixed section 22. One of the cuttable section 21 and the fixed section 22 is connected to the drain inlet 1, and the other is connected to the drain outlet 3. The cuttable section 21 can be cut to adjust the length of the drain guide 2. The adjacent ends of the cuttable section 21 and the fixed section 22 are sealed together, allowing the length of the drain guide 2 to be flexibly adjusted according to the actual installation space, effectively adapting to toilets with different pit distances, significantly improving installation adaptability, and possessing the advantages of strong versatility and convenient installation.

[0045] Specifically, the cuttable segment 21 has a first end 211 and a second end 212, and the fixed segment 22 has a third end 221 and a fourth end 222. The first end 211 is connected to the sewage discharge section 3, the fourth end 222 is connected to the sewage inlet section 1, and the second end 212 is sealed to the third end 221.

[0046] In other embodiments, the first end 211 may be connected to the sewage inlet 1, and the fourth end 222 may be connected to the sewage outlet 3.

[0047] like Figure 2 As shown, the outer wall of the cutable section 21 is provided with multiple ribs 213 evenly distributed along its length. Each rib 213 extends circumferentially along the cutable section 21, and the area between adjacent ribs 213 forms a cuttable surface 215, providing a clear and precise cutting reference. This allows users to quickly identify the cutting position during the cutting process, ensuring a flat end after cutting and avoiding interference with subsequent connections. The outer wall of the cutable section 21 is provided with multiple numerical markings 214 distributed along its length. Each numerical marking 214 corresponds to the rough-in distance of different toilet sizes, and each numerical marking 214 is located on a rib 213. This allows users to directly select the corresponding numerical marking 214 for cutting based on the rough-in distance of the toilet to be installed, without additional measurement or calculation. This greatly improves installation efficiency and accuracy, avoiding miscuts due to measurement errors that could result in incompatibility with the toilet.

[0048] The second end 212 of the cutable segment 21 is connected to the third end 221 of the fixed segment 22 by a connecting component, and a sealing ring is provided between the second end 212 and the third end 221 for easy distinction. This sealing ring is named the first sealing ring 51.

[0049] The connecting assembly includes a clamp 6. The outer surface of the third end 221 has a limiting protrusion 223 extending circumferentially therefrom. The clamp 6 has a locking hole 63. The second end 212 is fitted over the third end 221, and the clamp 6 is fitted over the second end 212. The rib 213 at the end of the second end 212 and the limiting protrusion 223 are engaged in the locking hole 63. Specifically, the clamp 6 includes an upper clamp 61 and a lower clamp 62. The upper clamp 61 has buckles 611 at both ends, and the lower clamp 62 has slots 621 at both ends. During installation, the upper clamp 61 and the lower clamp 62 are located on the upper and lower sides of the second end 212, so that the buckles 611 engage with the slots 621, and the limiting protrusion 223 and the rib 213 at the end of the second end 212 are engaged in the locking hole 63, thus fixing the second end 212 to the third end 221. Figure 7 As shown.

[0050] The sewage inlet 1 includes an upper connecting pipe 11 and a lower connecting pipe 12. One end of the upper connecting pipe 11 has a sewage inlet 111 that connects to the sewage outlet 201. A second sealing ring 52 is provided inside the sewage inlet 111. The other end of the upper connecting pipe 11 is sealed to one end of the lower connecting pipe 12 by a third sealing ring 53. The other end of the lower connecting pipe 12 is integrally formed with the fixed section 22. The cutable section 21 is integrally formed with the sewage outlet 3. Specifically, the lower connecting pipe 12 and the fixed section 22, and the cutable section 21 and the sewage outlet 3 are separated by dotted lines, such as... Figure 6 As shown. The sewage discharge section 3 is fitted with a fourth sealing ring 54 to ensure a sealed connection between the sewage discharge section 3 and the sewage pipe on the ground. In other embodiments, the other end of the upper connecting pipe 11 and one end of the lower connecting pipe 12 can be sealed by adhesive bonding.

[0051] The upper connecting pipe 11 includes a horizontal section 112 and an elevated section 113. The horizontal section 112 is one end of the upper connecting pipe 11, and the elevated section 113 is the other end of the upper connecting pipe 11. The axis of the elevated section 113 is perpendicular to the axis of the horizontal section 112. The bottom surface of the inner side of the lower connecting pipe 12 is provided with a downward inclined surface 121 towards the sewage discharge section, which can promote the smooth discharge of sewage, reduce the risk of sewage retention, deposition and blockage, and improve sewage discharge efficiency.

[0052] The connecting fitting 10 also includes a support part 4, which is fixed below the sewage inlet 1. The support part 4 and the sewage outlet 3 are respectively provided with mounting holes 41 and 331 for locking them to the ground. Specifically, the support part 4 is integrally formed below the lower connecting pipe 12, and a support plate 31 is provided around the outside of the sewage outlet 3, with the mounting holes 331 located on the support plate 31. Preferably, the support part 4 can be set higher so that the sewage guide part 2 is inclined downwards towards the sewage outlet 3, thereby further promoting the smooth discharge of sewage. A locking part 114 is provided above the upper connecting pipe 11 to lock the upper connecting pipe 11 to the wall.

[0053] In this embodiment, the contaminant guide 2 is a flat tube, but it is not limited to this. In other embodiments, the contaminant guide can be a round tube or a tube with an irregular cross-section.

[0054] Please see Figures 11-14 As shown, a toilet of this utility model includes a toilet body 20, a drain outlet 201 on the rear side of the toilet body 20, and the aforementioned toilet drain connection fitting 10, with the inlet part 1 connected to the drain outlet 201.

[0055] The toilet body 20 includes a bladder 202, a drain pipe 203, and a skirt 204. One end of the drain pipe 203 is connected to the bladder 202, and the other end is provided with a drain outlet 201. A hollow cavity is formed inside the skirt 204. The bladder 202 and the drain pipe 203 are located in the cavity, and the bladder 202 is connected to the skirt 204. A placement space 210 for placing connecting accessories 10 is formed below the bladder 202 and the drain pipe 203.

[0056] The toilet body 20 also includes a liner support 206 and a pipe support 207. The liner support 206 is located at the bottom of the liner 202 and connects the liner 202 and the skirt 204. The pipe support 207 is located at the bottom of the drain pipe 203 and connects the drain pipe 203 and the skirt 204. Both the liner support 206 and the pipe support 207 are at least partially concave upwards, allowing the connecting fitting 10 to pass through. The liner support 206 and the pipe support 207 provide support to the liner 202 and the drain pipe 203, reducing the downward deformation of the liner 202 and the drain pipe 203. Secondly, because most of the bottom structure is hollow, the bottom of the skirt 204 is not under stress during the firing process and is prone to outward flipping or uneven deformation, resulting in poor blank quality. Therefore, the inner tube support 206 and the pipe support 207 also have the function of controlling the distance between the two sides of the bottom of the skirt 204, which can hold the two sides of the bottom of the skirt 204 and reduce the amount of deformation.

[0057] Because the skirt 204 has many open spaces in its inner cavity due to the need to avoid connecting fittings, and because the front end of the skirt 204 is composed of two layers of single-sided slurry, it is prone to cracking and outward deformation due to friction with the kiln plate during firing. Multiple ribs are arranged in the inner cavity of the skirt 204 to concentrate stress. Ribs are also provided in the inner cavity of the skirt 204, connecting the liner support 206 and the pipe support 207. To fully utilize the space of the skirt 204 cavity, a water inlet pipe cutout 2091 is made in the rib 209 above the liner support 206, and a single-sided slurry cutout 2081 is made in the single-sided slurry 208 at the front end of the skirt 204. The water inlet pipe of the jet hole passes through the water inlet pipe cutout 2091 and then exits through the single-sided slurry cutout 2081. This eliminates the need for a secondary water channel on the toilet body 20 to guide the water to the jet hole, reducing the weight of the porcelain.

[0058] This utility model also includes an adhesive ring 205, which is bonded to the outside of the drain outlet 201. When the inner diameter of the inlet 111 is larger than the outer diameter of the drain outlet 201, the adhesive ring 205 cooperates with the drain outlet 201. Before the adhesive ring 205 is bonded to the outside of the drain outlet 201, a hole of the same size as the inner diameter of the drain outlet 201 needs to be drilled in the middle using a hole punch, and then aligned with the drain outlet 201 for bonding.

[0059] The present invention relates to a toilet. For the structure and working principle of the toilet drain connection fittings, please refer to the preceding description, which will not be repeated here.

[0060] Example 2

[0061] Please see Figures 15-19 As shown, the toilet drain connection accessory and toilet of this utility model differ from Embodiment 1 in that the connection assembly includes a snap fastener 7 and a screw 8. The snap fastener 7 has a connecting hole 71, and the third end 221 has a corresponding threaded hole 224. The third end 221 is sleeved outside the second end 212, and the snap fastener 7 is sleeved outside the second end 212 and located in the area between adjacent ribs 213, that is, on the cuttable surface 215. Figure 19 As shown, the fastener 7 is limited by adjacent ribs 213, and the screw 8 passes through the connecting hole 71 and connects to the threaded hole 224. Specifically, there are two fasteners 7, located on the upper and lower sides of the second end 212. In other embodiments, the third end may have a connecting hole, and the fasteners may have corresponding threaded holes.

[0062] In this embodiment, as Figure 18 As shown, the axis of the heightening section 113 is inclined relative to the axis of the horizontal section 112, which can further promote sewage discharge. The lower connecting pipe 12 and the fixed section 22, the cutable section 21 and the sewage discharge section 3 are separated by dashed lines.

[0063] This utility model relates to a toilet drain connection accessory and a toilet. The parts not described herein are the same as or can be implemented using existing technologies.

[0064] The above embodiments are only used to further illustrate a toilet drain connection accessory and toilet of the present invention.
