[0002] Setting an S-shaped structure at a local position of the sewer system can play an odor-proof role. The two ends of the S-shaped structure are respectively connected to sewer pipes. Water enters the S-shaped structure from one sewer pipe and is then discharged through the other sewer pipe. The S-shaped structure itself is usually connected by multiple sections of curved pipes. The connection position of the S-shaped structure itself and the connection position between the sewer pipe and the S-shaped structure are usually threaded.

[0003] A Chinese patent with publication number CN215759381U discloses an odor-proof drain bend, comprising a drain pipe, a first U-shaped tube and a second U-shaped tube, wherein one end of the first U-shaped tube is connected to the drain pipe, and the other end of the first U-shaped tube is connected to one end of the second U-shaped tube to form an S-shaped structure. Obviously, the other end of the second U-shaped tube is connected to another drain pipe to discharge water.

At the same time, the S-shaped structure needs to be equipped with joints and nuts, resulting in high costs. In addition, there are safety hazards of water leakage and air leakage at each connection position. Utility Model Content

[0041] Unless otherwise defined, the technical terms or scientific terms used in this specification and claims shall have the common meanings understood by persons having ordinary skills in the technical field to which the present invention belongs.

[0042] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0043] In addition, in the introduction to the pipe S-bend shaping device, the "inlet" and "outlet" involved are understood in conjunction with the installation process. During installation, the end of each channel for the flexible pipe to enter is the inlet, and the end for the flexible pipe to extend is the outlet. For example, the end of the first channel 11 for the flexible pipe to enter is the inlet 12 of the first channel, and the end of the first channel 11 for the flexible pipe to extend is the outlet 13 of the first channel.

[0044] refer to Figures 1 to 3 Understand. The embodiment of the utility model provides a downpipe 5 system, which can be used in environments such as the water outlet of a wash basin in a bathroom and the water outlet of a kitchen sink. The downpipe 5 system includes a downpipe 5 and a pipe S-bend shaping device. The downpipe 5 adopts a flexible pipe, which is shaped by the pipe S-bend shaping device to form an S-bend to achieve a deodorizing function.

[0045] The flexible pipe has a certain flexibility and can be curved under the action of external force. The flexible pipe can be realized by using existing technology, such as a pipe with a spiral elastic ring built in, or a corrugated pipe. The pipe S-bend shaping device can be realized by using the solution provided by any of the following embodiments.

[0046] The present utility model provides a pipe S-bend shaping device, which is used to make a flexible pipe present an S-bend. The pipe S-bend shaping device can be applied to various types of sewer pipe systems, such as the above-mentioned sewer pipe system. It should be noted that in actual applications, the S-bend presented by the pipe S-bend shaping device can be vertical, horizontal or inclined. Figure 2 The corresponding S-bend is horizontal. Figure 2 After rotating 90° clockwise, the corresponding S-bend is vertical. Figure 2 After rotating 45°, the corresponding S-bend is in an inclined state.

[0047] In an embodiment of the utility model, the pipeline S-bend shaping device includes a first shaping tube 1, a second shaping tube 2 and a connecting piece 3. The first shaping tube 1 and the second shaping tube 2 are respectively used to shape the flexible pipeline, and the connecting piece 3 is used to connect the first shaping tube 1 and the second shaping tube 2 so that the two are relatively fixed.

[0048] The first shaping tube 1 has a first channel 11 for the flexible pipe to pass through, and the second shaping tube 2 has a second channel 21 for the flexible pipe to pass through. The first shaping tube 1 and the second shaping tube 2 are spaced apart by a connector 3 to form a third channel 4 therebetween for the flexible pipe to pass through.

[0049] When the inlet 12 of the first channel is defined as being higher than the outlet 13 of the first channel, the inlet 22 of the second channel is not lower than the outlet 13 of the first channel, and the outlet 23 of the second channel is lower than the inlet 22 of the second channel, so that the flexible pipe extending from the outlet 13 of the first channel can first extend toward the inlet 12 of the first channel, and then extend toward the outlet 23 of the second channel, thereby forming an S-bend. It should be noted that the definition of the inlet 12 of the first channel being higher than the outlet 13 of the first channel here is to clearly express the structural relationship between the first channel 11 and the second channel 21. The orientation is not a limitation on the structure. In actual applications, the inlet 12 and outlet of the first channel can also be located at the same height.

[0050] refer to Figure 2 Understand that during installation, the flexible pipe of the down pipe 5 is Figure 2 The direction indicated by the arrow in the middle sequentially passes through the first channel 11, the third channel 4 and the second channel 21 to form an S-bend, one end of the downpipe 5 is connected to the pool, and the other end of the downpipe 5 is connected to the sewage system of the building. After installation, the pipe S-bend shaping device and the downpipe 5 are always kept together to shape the downpipe 5.

[0051] As can be seen from the above, the down pipe 5 is an integral type, and an S-bend is formed in a local position of the down pipe 5 by using a pipe S-bend forming device. During installation, the down pipe 5 only needs to be passed through the pipe S-bend forming device according to the above method. Compared with the prior art, the connection operation of the S-shaped structure itself and the connection operation between the S-shaped structure and the down pipe 5 are omitted, thereby simplifying the connection steps and saving installation time. At the same time, the S-bend formed by the pipe S-bend forming device and the other parts of the down pipe 5 are integrated into one, so that there is no need to equip joints and nuts for connecting the S-bend and the other parts of the down pipe 5, thereby reducing costs, and there is no risk of water leakage and air leakage at both ends of the S-bend.

[0052] In some embodiments, the inner diameter of the first forming tube 1 and the inner diameter of the second forming tube 2 are respectively adapted to the outer diameter of the flexible pipe. For example, the shape of the first channel 11 and the shape of the second channel 21 are the same as the shape of the sewer pipe 5, both of which are circular. For another example, the inner diameter of the first forming tube 1 and the inner diameter of the second forming tube 2 are the same as the outer diameter of the sewer pipe 5, or are slightly larger than the outer diameter of the sewer pipe 5. Therefore, while the first forming tube 1 and the second forming tube 2 allow the sewer pipe 5 to pass through, static friction is formed between them and the sewer pipe 5 to fix each other, thereby improving the stability of the S-bend and the reliability of the sewer pipe 5 system.

[0053] In some embodiments, Figure 1 As shown, the first shaping tube 1 is a round tube so as to have more contact area with the down pipe 5, thereby achieving a better shaping effect on the down pipe 5. Of course, in other embodiments, the first shaping tube 1 is a square tube, an oval tube or a tube with a special cross section, which is also within the protection scope of the utility model. Accordingly, the first shaping tube 1 can partially fit the flexible pipe so as to be fixed to each other.
