[0030] Example

[0031] Please refer to Figure 1 and Figure 4 As shown, this embodiment provides a drainage pipe fitting, including: a first drainage pipe 10, a flap assembly 20, a second drainage pipe 103, a cleaning pipe 102, and a sliding assembly 30. The first drainage pipe 10 has a collecting port 101; the flap assembly 20 is rotatably installed at the collecting port 101 to adjust the size of the collecting port 101; the second drainage pipe 103 is connected to the first drainage pipe 10; one end of the cleaning pipe 102 is connected to the second drainage pipe 103 and has an angle with the second drainage pipe 103, and the other end extends toward the collecting port 101; the sliding assembly 30 is slidably installed in the first drainage pipe 10 to slide against the inner wall of the first drainage pipe 10 to isolate odor.

[0032] In this embodiment, if Figure 1 As shown, the flip assembly 20 is rotatably installed at the collection port 101. According to the flow rate of the water flow, the flip assembly is opened and closed accordingly. When the drainage is completed, the flip assembly simply blocks the collection port 101 to prevent foreign matter from falling into the pipe and odor from escaping from the pipe. The sliding assembly 30 is installed in the first drainage pipe 10 and is located at one end close to the second drainage pipe 103 to abut against the inner wall of the first drainage pipe 10 to isolate the odor from escaping, thereby further improving the pipe's barrier to odor. By installing a cleaning pipe 102 at the second pipe, the pipe is directly cleaned through the cleaning pipe 102, reducing the disassembly of the pipe during the cleaning process, and improving the convenience of use and maintenance.

[0033] Further, in some implementations of this embodiment, Figure 1 to Figure 2As shown, it also includes: a sleeve 104. The sleeve 104 is rotatably mounted on the outer wall of the first drain pipe 10, and moves toward the second drain pipe 103 to abut against the second drain pipe 103, thereby fixing the relative positions of the first drain pipe 10 and the second drain pipe 103.

[0034] In this embodiment, if Figure 1 As shown, the sleeve 104 is rotatably installed on the first drain pipe 10 and is located at one end close to the second drain pipe 103. The sleeve 104 and the second drain pipe 103 are threadedly connected, and a sealing gasket is installed between the first drain pipe 10 and the second drain pipe 103 for connecting the first drain pipe 10 and the second drain pipe 103, thereby improving the efficiency of the second drain pipe 103 in receiving sewage collected by the first drain pipe 10 and reducing the odor emission between the first drain pipe 10 and the second drain pipe 103.

[0035] Further, in some implementations of this embodiment, Figure 1 and Figure 4 , Figure 5 , Figure 6 As shown, the flap assembly 20 includes: a mounting cover 201 and a plurality of blades 202. The mounting cover 201 is mounted at the collecting port 101; the plurality of blades 202 are rotatably mounted on the inner wall of the mounting cover 201, and the plurality of blades 202 are spaced apart and distributed on the inner wall of the collecting port 101.

[0036] In this embodiment, if Figure 6 As shown, the blade 202 is rotatably mounted in the mounting cover 201, as shown in FIG. Figure 5 As shown, both ends of the blade 202 are inserted into the side wall of the mounting cover 201. Figure 4 As shown, the mounting cover 201 has a larger accommodating space, which increases the collection surface for sewage, thereby improving the collection efficiency, and further increasing the flow rate of the water flow in the first drain pipe 10.

[0037] Further, in some implementations of this embodiment, Figures 4 to 6 As shown, the flip assembly 20 further includes: a sliding plate 203 and a first elastic element 204. A mounting groove is provided on the side wall of the mounting cover 201, and the sliding plate 203 is slidably mounted in the mounting groove, and the blade 202 is penetrated through the inner wall of the mounting groove, and one end of the blade 202 extending into the mounting groove is abutted against the sliding plate 203; the first elastic element 204 is installed in the mounting groove, one end of which is fixed in the mounting groove, and the other end of which is abutted against the sliding plate 203.

[0038] In this embodiment, if Figure 5As shown, mounting grooves are opened in the side walls on both sides of the mounting cover 201, and the two ends of the blade 202 extend into the mounting grooves on both sides respectively. Through the first elastic element 204, specifically a spring, the sliding plate 203 is driven to abut and push the end of the blade 202 away from the rotating shaft, thereby driving the blade 202 to rotate around the rotating shaft. The rotation between the multiple blades 202 can cover the mouth of the mounting cover 201 to reduce the odor emitted from the collection port 101.

[0039] Further, in some implementations of this embodiment, Figure 1 and Figure 4 As shown, the cleaning tube 102 further includes a cover plate 105 . The cover plate 105 is installed on the cleaning tube 102 .

[0040] In this embodiment, if Figure 1 As shown, there is an angle between the cleaning pipe 102 and the second drain pipe 103, specifically 30° to 45°, which is convenient for entering the second drain pipe 103 from the cleaning pipe 102 during cleaning, thereby improving the cleaning efficiency. One end of the cleaning pipe 102 installed with the cover plate 105 extends toward the collecting port 101, and the cover plate 105 blocks the pipe opening of the cleaning pipe 102, thereby reducing the escape of odor in the pipe.

[0041] Further, in some implementations of this embodiment, Figures 4 to 7 As shown, the sliding assembly 30 includes: a cover plate 301, a limiting ring 302, a stop ring 106, and a second elastic element 303. The cover plate 301 is slidably mounted on the first drain pipe 10; the limiting ring 302 is mounted on the cover plate 301 and abuts against the outer wall of the first drain pipe 10; the stop ring 106 is mounted on the first drain pipe 10, and the movement of the cover plate 301 drives the limiting ring 302 to move toward the stop ring 106; the second elastic element 303 is mounted between the limiting ring 302 and the stop ring 106, and pushes the limiting ring 302 to move in a direction away from the stop ring 106.

[0042] In this embodiment, if Figure 4 and Figure 5 As shown, the portion of the cover plate 301 inside the first drain pipe 10 has a curved surface, which increases the contact area with the sewage, improves the opening and closing accuracy of the cover plate 301, and reduces the accumulation of sewage at the connection. Figure 7 As shown, the cover plate 301 abuts against the end face of the stop ring 106 and the side wall of the first drain pipe 10 to seal the pipe mouth of the first drain pipe 10. The second elastic element 303, which is specifically a spring, is installed between the stop ring 106 and the limiting ring 302 to apply a force away from the stop ring 106 to the limiting ring 302, so that the cover plate 301 maintains blocking the first drain pipe 10 when no sewage flows through, thereby reducing the spread of odor.

[0043] Further, in some implementations of this embodiment, Figure 3 and Figure 7 As shown, a plurality of drainage openings 304 are provided on the cover plate 301 , and the plurality of drainage openings 304 are distributed at intervals along the circumference of the cover plate 301 , and the plurality of drainage openings 304 abut against the side wall of the first drainage pipe 10 to block odor.

[0044] In this embodiment, if Figure 7 As shown, the drain port 304 is provided on the cover plate 301, and when it abuts against the stop ring 106 and the end surface of the side wall of the first drain pipe 10, the pipe opening of the first drain pipe 10 is blocked. Driven by the sewage in the first drain pipe 10, the cover plate 301 moves toward the end away from the first drain pipe 10, and the sewage enters the second drain pipe 103 from the drain port 304. Figure 3 As shown, a plurality of drainage openings 304 are distributed at intervals on the cover plate 301 and distributed along the circumference of the cover plate 301 .

[0045] In summary, when a drainage pipe fitting is used, sewage enters the collecting port 101 through the installation cover 201. When sewage enters, the blades 202 are rotated to compress the first elastic element 204. The sewage enters the first drainage pipe 10 from the installation cover 201 through the collecting port 101. The sewage abuts against the cover plate 301, driving the limit ring 302 to slide to compress the second elastic element 303, so that the cover plate 301 moves toward the second drainage pipe 103 along the axial direction of the first drainage pipe 10. The sewage flows into the second drainage pipe 103 from the multiple drainage ports 304 on the cover plate 301. The cover plate 301 with a curved surface reduces the accumulation of sewage at the connection. And under the action of the second elastic element 303, the drain outlet 304 abuts against the end of the first drain pipe 10 and the stop ring 106 to drive the cover plate 301 to block the first drain pipe 10 and reduce the spread of odor. The first elastic element 204 drives the sliding plate 203 to push the blade 202 to rotate, and the mouth of the installation cover 201 is covered to further reduce the spread of odor and prevent foreign matter from falling into the pipe fittings, thereby improving the safety of use. By installing the cleaning pipe 102 and the cover plate 105, the disassembly and assembly of the pipe fittings when cleaning the pipe 102 is reduced, thereby improving the convenience of use. The rotation and fixation of the sleeve 104 improves the installation efficiency.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
