One end of the extender connects to the toilet body, and the other end connects to the drain pipe via the sealing flange assembly. The extender is also fixed to the side wall of the toilet via the side-fixing assembly. Currently, the toilet body's drain pipe is directly inserted into the top interface of the extender without a guide. The disadvantages of this structure are:
[0003] 1. If the toilet drain pipe is directly inserted into the top interface of the toilet extender, it is difficult to align the center of the drain pipe opening with the center axis of the sealing gasket. This will accelerate the aging of the sealing gasket, affect its service life, and easily cause leakage.
[0004] 2. The toilet body's drain pipe is directly inserted into the top interface of the toilet extender. After the drain pipe is inserted, the sealing surface only has a radial seal, resulting in poor sealing reliability. Utility Model Content:

The toilet extender is also fixed to the side wall of the toilet body via a side fixing assembly. One end of the guide sleeve is fixed to the interface of the toilet extender, and the other end is fixed to the drain pipe outlet of the toilet body. The guide sleeve has a stepped cylindrical structure. The upper part of the inner wall that connects with the drain pipe outlet of the toilet body is provided with spaced-apart oblique guide ribs, and the lower part of the stepped surface that connects with the interface of the toilet extender forms a sealing end face.
[0008] Furthermore, the inclined guide ribs on the guide sleeve are arranged at intervals along the upper inner circumference of the guide sleeve, and each inclined guide rib has a near-triangular plate-like structure from the upper surface edge of the step surface to the upper end of the guide sleeve.
[0009] Further, the interface bottom of the toilet extender forms a platform, the radial seal is arranged in the interface, the top covers the upper end of the interface, the guide sleeve is clamped outside the interface of the toilet extender to ensure that the stepped surface of the guide sleeve presses the radial seal, the sewage pipe of the toilet body is inserted from above the guide sleeve to the platform of the interface bottom of the toilet extender, the outer wall of the sewage pipe is close to the radial seal to form a radial seal, and the stepped surface of the guide sleeve is close to the upper end of the radial seal to form an end face seal.
[0010] Further, the interface outer surface of the toilet extender is provided with a boss, and the bottom end of the guide sleeve is formed with a clamping hook to be clamped on the boss to be positioned.
[0011] By adopting the technical scheme, the utility model has the advantages that, compared with the prior art, the utility model has the advantages that:
[0012] 1. The guide sleeve structure is added, the head of the guide sleeve is provided with inclined guide ribs, the guide sleeve plays a good guiding role in the process of blind installation of the toilet, the sewage pipe of the toilet body is directly inserted into the center axis of the radial seal to be directly centered, the sealing is good, and long-term use of the sealing ring is facilitated.
[0013] 2. The stepped surface of the guide sleeve clamps the radial seal and the interface of the toilet extender to form an end face seal, the end face seal is added while the radial seal is kept, and the reliability of the sealing is greatly increased. BRIEF DESCRIPTION OF DRAWINGS
