Background Technology

[0002] Traditional bathroom drainage systems often use small-diameter round floor drains (usually 50mm in diameter) paired with PVC pipes, which has significant drawbacks:

[0003] 1. Low drainage efficiency: Round floor drains have a small water collection area, which makes them prone to clogging by hair, resulting in slow drainage and water accumulation during showering;

[0004] 2. Construction depends on slope: Precise ground slope (1%-3%) is required to guide water flow, making construction difficult and with a low margin for error;

[0005] 3. High maintenance costs: Dirt easily accumulates in pipe bends, requiring frequent disassembly and cleaning; dried-out water traps can easily cause odors.

[0006] 4. Insufficient compatibility: Existing floor drains are difficult to adapt to high-flow scenarios (such as multiple people showering or smart bathroom equipment), and are prone to overflow and leakage. Utility Model Content

[0007] In response to the above-mentioned problems, this utility model aims to solve the problems of low drainage efficiency, high construction difficulty and insufficient compatibility of traditional bathroom drainage systems, and provides a bathroom trough-type drainage pipe fitting that is efficient in drainage, easy to install, convenient to maintain and can adapt to high-flow drainage scenarios.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A bathroom trough-type drainage pipe fitting includes an adjustable plastic drainage trough, a trough connector, and a central drainage connector assembled together. The adjustable plastic drainage trough is a U-shaped trough structure with one open end, symmetrically arranged at both ends of the trough connector.
