[0002] In building drainage systems, water seal fittings are crucial components for preventing sewer gas from flowing back into the building. Traditional water seal fittings, such as S-shaped or P-shaped traps, typically require individual installation at each drainage point. This not only increases installation complexity and cost but also makes them difficult to arrange in space-constrained locations. Furthermore, the need for regular maintenance to prevent the water seal from drying out further increases the difficulty and frequency of maintenance.

[0003] With the development of building technology and the increasing demands for environmental protection, the market has placed higher requirements on drainage pipe fittings, including simplified installation, reduced maintenance, improved space utilization, and enhanced water seal reliability. However, existing water seal pipe fittings still have certain limitations in meeting these requirements:

[0004] Traditional water seal pipe fittings are complex to install, take up a lot of space, and are not suitable for space-constrained locations; multiple drainage points require multiple independent water traps, which increases costs and maintenance workload. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1-4 As shown, the shared water seal pipe fitting of this utility model includes:

[0030] The outer liner 1 has a water inlet 11 and a water outlet 12 on its two sides respectively; a water seal groove 13 is provided at the bottom of the outer liner 1.

[0031] The inner liner 2 is embedded inside the outer liner 1 to form an isolation chamber with the outer liner 1; the bottom of the inner liner 2 is provided with a water outlet 22, the height of the water outlet 22 is lower than the height of the water inlet 11 and the water outlet 12, and the water outlet 22 is connected to the water seal groove 13. When water flows out from the water outlet 22 of the inner liner 2 and enters the water seal groove 13, a water seal 100 is formed between the inner liner 2 and the outer liner 1.

[0032] A water funnel 3 is provided at the top of the inner liner 2 to prevent debris from entering the inner liner 2.

[0033] Based on the above-described structure of the shared water seal fitting, after the inner liner 2 is embedded into the outer liner 1, the isolation baffle 21 is fastened to the top of the outer liner 1, so that the outer liner 1 and the inner liner 2 form an isolation chamber structure. The water seal 100 at the bottom of the outer liner 1 achieves air isolation between the pipes, effectively preventing odor backflow. The water funnel 3 helps to prevent debris from entering the inner liner 2, maintain the stability of the water seal and the cleanliness of the fitting, and can be used to replace traditional S-type or P-type water trap fittings. In addition, water can be injected into the water seal groove 13 through the outlet 22 of the inner liner 2 until the water level reaches the required height, preventing the water seal 100 from drying out.

[0034] Furthermore, a slot 14 is provided on the inner wall of the outer liner 1, and a connecting partition 23 adapted to the slot 14 is provided on the outer wall of the inner liner 2. The design of the connecting partition 23 and the slot 14 is to realize the detachable connection between the inner liner 2 and the outer liner 1, which helps to simplify the installation process and facilitates disassembly when needed, making maintenance and cleaning easier.

[0035] Furthermore, the inner liner 2 is provided with an isolation baffle 21 at its top, the size of which is adapted to the outer diameter of the outer liner. The isolation baffle 21 can fit tightly with the outer liner, enhancing the sealing performance of the entire pipe fitting and reducing the possibility of gas leakage.

[0036] In addition, a cover plate 4 is provided above the water funnel 3. The cover plate 4 is designed to help prevent large particles of debris from entering the water funnel 3, while allowing water to flow smoothly, maintaining the water seal 100 liquid level and protecting the water seal core.

[0037] To ensure sufficient depth of the water seal 100, the depth of the water seal groove 13 is at least 20 mm. This design effectively prevents backflow of sewer gas and also prevents the water seal 100 from drying out.

[0038] In this embodiment, a water seal core is provided inside the water seal tank 13. The water seal core inside the water seal tank 13 further improves the sealing effect of the water seal 100, reduces the evaporation loss of the water seal 100, and maintains the stability of the water seal 100.

[0039] Preferably, the water funnel 3 includes a funnel body 31, with a water inlet at the top of the funnel body 31, and a plurality of filter holes on the side walls and bottom of the funnel body 31. The design of the filter holes helps to disperse the water flow, reduce the impact of the water flow on the water seal 100, and at the same time filter impurities to protect the water seal core.

[0040] In this embodiment, a supporting edge 32 is provided around the top perimeter of the funnel body 31 to support the water funnel 3 within the inner liner 2. The supporting edge 32 provides stable support for the water funnel 3 within the inner liner 2, ensuring that the position of the water funnel 3 is fixed and preventing displacement due to water flow impact. It also allows for quick replacement and facilitates cleaning and maintenance.

[0041] Furthermore, both the water inlet 11 and the water outlet 12 are provided with pipe overlap parts 111 for overlapping with other pipes, and the pipe overlap parts 111 are in an outward V-shape.

[0042] Furthermore, sealing rings are provided inside the water inlet 11 and the water outlet 12. The sealing rings inside the water inlet 11 and the water outlet 12 enhance the sealing performance of the connection, effectively prevent water leakage, and ensure the sealing of the pipeline connection and the effect of the water seal 100.

[0043] This utility model also discloses a drainage system, including a shared water seal pipe fitting with the structure described above, and a basin drain pipe, a shower room drain pipe, and a floor drain pipe connected to the shared water seal pipe fitting.

[0044] By connecting the shared water seal fittings to the basin drain pipe, shower room drain pipe, and floor drain pipe, a highly efficient drainage system is formed, which simplifies the layout of the drainage system and improves drainage efficiency. The shared water seal fittings can continuously replenish water to maintain the water seal level, preventing dryness and backflow odor. At the same time, each drainage pipe is isolated from the others, reducing crossflow interference.

[0045] During installation, the shared water seal pipe fitting can be embedded into the floor tile 101, ensuring that the cover plate 4 is flush with the floor tile. Figure 4 As shown, the basin drain pipe, shower room drain pipe and floor drain pipe are then connected to the inlet 11 and outlet 12 of the shared water seal fitting, respectively.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
