DETAILED DESCRIPTION

[0033] The utility model discloses a specific embodiment as follows and further describes the technical scheme of the utility model in connection with the drawings, but the utility model is not limited to these embodiments.

[0034] As shown in the utility model discloses a sewer, comprising: the pipe 100, the connecting pipe 200, the connecting piece 300, the drain pipe 400. Figures 1 to 6

[0035] Specifically, one end of the connecting pipe 200 is inserted into the pipe 100.

[0036] The connecting piece 300 is connected between the connecting pipe 200 and the pipe 100 and can move relative to the pipe 100, and is used for fastening the connection between the connecting pipe 200 and the pipe 100.

[0037] The drain pipe 400 is connected to the side wall of the pipe 100.

[0038] The drain pipe 400 and the pipe 100 are provided with an avoiding structure 500, and the avoiding structure 500 is arranged on the moving path of the connecting piece 300 moving towards the pipe 100, so as to provide space for the movement of the connecting piece 300.

[0039] The insertion between the connecting pipe 200 and the pipe 100 can be that one end of the connecting pipe 200 is inserted into the pipe 100, or one end of the pipe 100 is inserted into the connecting pipe 200, which is used for realizing the primary connection of the two. The other end of the connecting pipe 200 is connected to the water outlet 211 of the sink, so as to guide the waste water discharged from the sink into the pipe 100, and then discharge the waste water into the sewer through the drain pipe 400. Preferably, the end of the connecting pipe 200 connected to the sink is provided with a clamping type connector, which is used for firmly fixing the connecting pipe 200 to the water outlet 211 of the sink. The connecting piece 300 is used for ensuring the stable connection between the connecting pipe 200 and the pipe 100, so that the two are combined more closely.

[0040] In the scheme, the avoiding structure 500 is arranged between the drain pipe 400 and the pipe 100, which provides the necessary space for the movement of the connecting piece 300 when the connecting piece 300 moves towards the pipe 100 to fix the connecting pipe 200 and the pipe 100. In this way, without increasing the length of the pipe 100, sufficient space is provided for the movement of the connecting piece 300, and the space occupied by the whole sewer and the amount of materials used are reduced, so that the installation and disassembly of the sewer are more convenient.

[0041] The avoiding structure 500 is formed by the outer side wall of the pipe 100 and / or the drain pipe 400 being recessed away from the connecting piece 300.

[0042] ​In one embodiment, the avoiding structure is designed as a curved surface towards the outer end surface of the connecting piece 300. By adjusting the curvature of the curved surface, the size of the avoiding structure can be controlled to adapt to the avoiding space required by connecting pieces 300 of different specifications. Along the axis direction of the drain pipe 400, and as far away from the receiving pipe 100, the maximum distance of the curved surface to the axis of the drain pipe 400 gradually increases.

[0043] The side wall of the connecting pipe 200 is provided with an external connecting pipe 210, which is designed to meet the drainage requirements of other equipment (such as a dishwasher) around the sink. The external connecting pipe 210 is in communication with the inside of the connecting pipe 200, ensuring that the fluid can be smoothly introduced into the connecting pipe 200 from the external connecting pipe 210.

[0044] In one embodiment, the connecting pipe 200 is internally provided with a flow guide 220, and the external connecting pipe 210 forms a water outlet 211 on the side wall of the connecting pipe 200, which is opposite to the flow guide 220, and is used to guide the fluid introduced into the connecting pipe 200 from the external connecting pipe 210 into the receiving pipe 100.

[0045] The external connecting pipe 210 is connected to the side wall of the connecting pipe 200. When the external connecting pipe 210 is watered and the water pressure is large, it may cause the wastewater introduced into the connecting pipe 200 from the external connecting pipe 210 to flow reversely into the sink from the end of the connecting pipe 200 connected to the sink, causing backflow. However, the flow guide 220 arranged opposite to the water outlet 211 formed by the external connecting pipe 210 on the connecting pipe 200 effectively solves this problem, ensuring that the wastewater introduced into the connecting pipe 200 from the external connecting pipe 210 can flow smoothly into the receiving pipe 100, preventing backflow.

[0046] Preferably, the external connecting pipe 210 is inclined to be connected to the connecting pipe 200, which is used to reduce the impact of the wastewater introduced into the connecting pipe 200 from the external connecting pipe 210 on the flow guide 220.

[0047] The flow guide 220 includes a first extension section 221 and a second extension section 222, one end of the first extension section 221 is connected to one end of the second extension section 222 and they are arranged at an angle therebetween, the other end of the first extension section 221 is connected to the inner wall of the connecting pipe 200, and the other end of the second extension section 222 is arranged towards the receiving pipe 100.

[0048] Preferably, the first extension section 221, the second extension section 222 and the connecting pipe 200 are integrally formed. The first extension section 221 is substantially parallel to the radial direction of the connecting pipe 200, and the second extension section 222 is substantially parallel to the axis direction of the connecting pipe 200. Therefore, the first extension section 221 and the second extension section 222 form an almost vertical angle therebetween, which helps to more effectively prevent the wastewater introduced into the connecting pipe 200 from the external connecting pipe 210 from backflowing.

[0049] An elastic sealing member 600 is arranged between the connecting pipe 200 and the receiving pipe 100 to provide a seal between the connecting pipe 200 and the receiving pipe 100.

[0050] When the connection between the connecting pipe 200 and the receiving pipe 100 is fastened by the connecting member 300, the elastic sealing member 600 is pressed by the two pipes, so that the elastic sealing member 600 better fills the gap between the connecting pipe 200 and the receiving pipe 100, thereby better sealing the connecting pipe 200 and the receiving pipe 100.

[0051] The connecting pipe 200 is provided with a first limiting portion 230 on the outside, the connecting member 300 comprises an inner thread 310 and a second limiting portion 320, the second limiting portion 320 is in movable abutment with the first limiting portion 230, and the receiving pipe 100 is provided with an outer thread 110 matched with the inner thread 310.

[0052] Referring to Figure 3 During the rotation of the connecting member 300 to connect the inner thread 310 with the outer thread 110 on the receiving pipe 100, the second limiting portion 320 pushes the first limiting portion 230, so that the insertion between the connecting pipe 200 and the receiving pipe 100 is more compact, thereby achieving stable fixation between the two.
