[0002] With social development, in the field of modern architectural decoration, people's pursuit of the utilization, functionality and innovation of bathroom space is constantly improving. Bathroom cabinets are mostly suspended, and the drain pipes are made into wall-mounted drains. This avoids the risk of water damage to the bathroom cabinets, while the space below can be used to place basins and bath products, making full use of the space.
[0003] Currently, the common drainage method for bathroom vanities is to use a PVC corrugated flexible hose that connects the sink to the wall-mounted drain pipe. This method is simple, economical, and practical, and has been widely adopted. However, due to poor sealing, sewage odors can easily back up, and insects can crawl out along the drain pipe, while debris can easily clog the wall-mounted drain pipe. To solve this technical problem, a U-shaped pipe is usually installed at the drain pipe to prevent backflow of odors through a water seal. However, during use, debris can easily accumulate at the U-shaped pipe, and dirt can easily accumulate on the pipe wall, which can cause blockages and odors over time. Utility Model Content

Detailed Implementation
[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Example 1: This example aims to propose a bathroom cabinet wall drain assembly that is odor-proof, insect-proof, and clog-proof.
[0040] according to Figures 1-3 As shown, it includes pipe connectors, a vertically installed U-shaped water seal pipe 3, a sewage pipe 4, an insect-proof pipe 12, a cleaning ball 14, and a wall-mounted pre-embedded pipe.
[0041] Pipe fittings are used to connect to the washbasin;
[0042] The U-shaped water seal pipe 3 is located below the pipe connector. One end of the U-shaped water seal pipe 3 is connected to the pipe connector. The pipe connector includes a drain 1 and a universal interface 2. The lower end of the drain 1 is fixedly connected to the universal interface 2. The drain 1 is connected to the sink. The lower end of the universal interface 2 is connected to the U-shaped water seal pipe 3.
[0043] The sewage pipe 4 is fixedly connected to the bottom of the U-shaped water seal pipe 3, and the U-shaped water seal pipe 3 is connected to the U-shaped water seal pipe 3. The lower surface of the U-shaped water seal pipe 3 extends downward to form a tubular structure connected to the U-shaped water seal pipe 3. The bottom of the tubular structure is fixedly connected to the upper end of the sewage pipe 4. An avoidance opening connected to the tubular structure is opened in the middle of the inner wall of the U-shaped water seal pipe 3.
[0044] The sewage pipe 4 is set vertically, and the lower part of the outer surface of the sewage pipe 4 is provided with a threaded structure. The sewage pipe 4 is connected to the sewage cover 9 through the threaded structure.
[0045] The insect-proof pipe 12 is equipped with an insect-proof filter structure. A transition pipe is provided between the U-shaped water seal pipe 3 and the insect-proof pipe 12. The transition pipe includes a connecting pipe 5 and a corrugated drainage hose 6. The connecting pipe 5 is connected to the corrugated drainage hose 6 and the U-shaped water seal pipe 3. The end of the corrugated drainage hose 6 closest to the insect-proof pipe 12 is connected to the insect-proof pipe 12.
[0046] The pipe structure formed after the U-shaped water seal pipe 3 is connected to the pipe connector presents a situation where the side of the pipe connector is higher than the other side, thereby preventing the liquid in the U-shaped water seal pipe 3 from flowing back into the basin. When the internal liquid level is too high, the liquid flows into the transition pipe from the other end.
[0047] The insect-proof filter structure is an insect-proof filter plate 13, which is fixedly connected to the inner wall of the insect-proof tube 12. The shape of the insect-proof filter plate 13 is adapted to the inner wall of the insect-proof tube 12.
[0048] One end of the wall-mounted pre-embedded pipe is connected to the insect-proof pipe 12, and the other end of the wall-mounted pre-embedded pipe is connected to the sewer drainage system. The wall-mounted pre-embedded pipe includes a drainage elbow 7 and a drainage pipe 8. The drainage pipe 8 is pre-embedded in the wall, and the drainage elbow 7 is fixedly connected to the top of the drainage pipe 8. The water inlet connection end of the drainage elbow 7 is located outside the wall, and the water inlet connection end of the drainage elbow 7 is connected to the insect-proof pipe 12.
[0049] The cleaning ball 14 is installed inside the sewage pipe 4. The sewage pipe 4 is equipped with a water inlet connection pipe 10, which is used to send external clean water into the sewage pipe 4. The clean water drives the cleaning ball 14 to roll inside the U-shaped water seal pipe 3.
[0050] The inlet pipe 10 is fixedly connected to the bottom of the drain cover 9. The inlet pipe 10 is connected to the drain pipe 4. The inlet pipe 10 is equipped with a control valve and a limiting structure to ensure that the cleaning ball 14 and the inlet pipe 10 are vertically aligned. The limiting structure includes a backflow preventer 15, which is fixedly connected to the bottom wall of the drain cover 9. The backflow preventer 15 is adapted to the shape of the inner wall of the drain pipe 4. The top of the backflow preventer 15 has a vertically open slot for liquid to pass through, and the diameter of the slot is smaller than the diameter of the cleaning ball 14.
[0051] When the drain cover 9 is opened, the backstop 15 moves downwards along with it. At this time, the cleaning ball 14 may fall out. The cleaning ball 14 can be placed in the bayonet. When the drain cover 9 is reset, the cleaning ball 14 returns to the U-shaped water seal pipe 3.
[0052] Working principle: When water flows from the basin into the pipe, the water flow washes the cleaning ball 14. Because the U-shaped water seal pipe 3 has a U-shaped structure inside, the cleaning ball 14 rolls back and forth.
[0053] When it is necessary to clean the U-shaped water seal pipe 3, connect the inlet connection pipe 10 to the water pipe, then open the control valve to send the liquid into the drain pipe 4. The clean water flows into the U-shaped water seal pipe 3 from bottom to top, causing the cleaning ball 14 to roll quickly in the U-shaped water seal pipe 3, which causes the dirt on the pipe wall of the U-shaped water seal pipe 3 to be knocked off.
[0054] Then open the drain cover to allow the debris and dirt inside the U-shaped water seal pipe to fall out.
[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
