[0002] In daily life, various pipes are everywhere, such as air conditioning pipes, toilets, squat toilets, urinals, sewers, etc. During long-term use, pipes are prone to blockage due to foreign objects.

[0003] Currently, pipe cleaning tools are typically used to clear blockages, such as by pressurizing or flushing the pipes to loosen and expel the obstructions. However, different types of foreign objects in the pipes require different cleaning tools, and the pipework of different cleaning tools cannot be fully adapted to the pipes being cleared, making the process inconvenient.

[0006] The inner diameter of the pipe segments arranged sequentially along the first direction increases section by section; or, the outer diameter of the pipe segments arranged sequentially along the first direction decreases section by section.

[0007] In one embodiment, as the inner diameter of the pipe segments arranged sequentially along the first direction increases section by section, the outer diameter of the pipe segments arranged sequentially along the first direction also increases section by section.

The second fitting is a flexible pipe that can deform, while the first fitting and the first pipe are both rigid pipes.

[0010] In one embodiment, the two ends of the flexible tube are respectively connected to the first pipe fitting and the connecting pipe segment by means of inner and outer sleeves.

[0011] In one embodiment, the outer peripheral walls at both ends of the flexible tube are threadedly connected to the inner peripheral wall of the first pipe fitting and the inner peripheral wall of the connecting pipe section, respectively.

[0012] In one embodiment, the first pipe fitting includes a first connecting pipe segment and a second connecting pipe segment that are sequentially connected along its own length direction. The first connecting pipe segment is sleeved on the periphery of the flexible pipe, and the inner diameter of the first connecting pipe segment is larger than the inner diameter of the second connecting pipe segment. An anti-slip part is formed on the outer peripheral wall of the first connecting pipe segment.

[0013] In one embodiment, the flexible tube includes a flexible corrugated tube with a corrugated longitudinal section and a flexible body for supporting the flexible corrugated tube.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1-7As shown, this application discloses a pipe cleaner. This pipe cleaner serves as a connecting pipe between the pipe to be unclogged and a cleaning device. The aforementioned pipe cleaner includes a first pipe 2, which includes a connected installation pipe section 2a and a connecting pipe section 2b. The connecting pipe section 2b is used to connect to the pipe to be unclogged, and the connecting pipe section 2b and the installation pipe section 2a are arranged sequentially along a first direction A. The installation pipe section 2a is connected to the pipe of the cleaning device for cleaning the pipe to be unclogged via an inner and outer casing. The installation pipe section 2a includes at least two pipe sections 21 connected sequentially along its length. Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the inner diameter of the pipe segments 21 arranged sequentially along the first direction A increases section by section; or, as... Figure 7 As shown, the outer diameter of the pipe segments 21 arranged sequentially along the first direction A decreases section by section.

[0035] It is understandable that, since the first pipe 2 and the cleaning device for cleaning the pipe to be dredged are installed in an inner and outer manner, and the first pipe 2 includes at least two pipe sections 21, when the inner diameter of the pipe sections 21 arranged sequentially along the first direction A increases, pipes with different outer diameters can be inserted into the corresponding pipe sections 21; and when the outer diameter of the pipe sections 21 arranged sequentially along the first direction A decreases, pipes with different inner diameters can be fitted around the corresponding pipe sections 21, that is, it can match cleaning device pipes of different diameters, with high matching degree, strong applicability and convenient cleaning.

[0036] It should be noted that "inner pipe diameter increases segment by segment" means that the inner pipe diameter of the subsequent pipe segment 21 is larger than that of the preceding pipe segment 21. "Outer pipe diameter decreases segment by segment" means that the outer pipe diameter of the preceding pipe segment 21 is larger than that of the subsequent pipe segment 21. Schematic, there are three pipe segments 21, which are sequentially arranged along the first direction A and defined as the first pipe segment 211, the second pipe segment 212, and the third pipe segment 213. Then, as... Figure 2 As shown, "the inner diameter of the pipe segments 21 arranged sequentially along the first direction A increases segment by segment" means that the inner diameter of the first pipe segment 211 is smaller than the inner diameter of the second pipe segment 212, and the inner diameter of the second pipe segment 212 is smaller than the inner diameter of the third pipe segment 213. Similarly, "the outer diameter of the pipe segments 21 arranged sequentially along the first direction A decreases segment by segment" means that the outer diameter of the first pipe segment 211 is larger than the outer diameter of the second pipe segment 212, and the outer diameter of the second pipe segment 212 is larger than the outer diameter of the third pipe segment 213. See [link to documentation] for details. Figure 7 As shown.

[0037] In addition, the aforementioned pipe section 21 can also consist of two, four, or more sections, depending on actual needs.

[0038] In this embodiment, as the inner diameter of the pipe segments 21 arranged sequentially along the first direction A increases section by section, the outer diameter of the pipe segments 21 arranged sequentially along the first direction A also increases section by section. In other embodiments, the outer diameter of the first pipe 2 may be the same at all points.

[0039] Additionally, it should be noted that the aforementioned connecting pipe section 2b and installation pipe section 2a can be an integral part or separate parts. In this embodiment, the connecting pipe section 2b and installation pipe section 2a are integrally formed.

[0040] Furthermore, the aforementioned pipe cleaner also includes a second pipe 1, one end of which is connected to the connecting pipe section 2b, and the other end of which is used to connect to the pipe to be dredged. At least a portion of the second pipe 1 is a deformable flexible part. Schematic, the second pipe 1 may be entirely deformable or partially deformable.

[0041] In this embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the second pipe 1 includes a first pipe fitting 11 and a second pipe fitting 12. The two ends of the second pipe fitting 12 are connected to the first pipe fitting 11 and the connecting pipe section 2b, respectively. The second pipe fitting 12 is a flexible pipe that can deform. The first pipe fitting 11 and the first pipe 2 are both rigid pipes.

[0042] Understandably, the second fitting 12 is designed as a flexible pipe, which can be bent, increasing the operable area during use, making it easier and less strenuous to operate. In contrast, both the first pipe 2 and the first fitting 11 are rigid pipes, ensuring a more stable and reliable connection between the cleaner and the pipe to be dredged.

[0043] like Figure 2 As shown, the inner and outer diameters of the connecting pipe section 2b are the same as those of the first pipe section 211, meaning that the connecting pipe section 2b and the first pipe section 211 are two parts of a straight pipe.

[0044] The first pipe fitting 11 and the second pipe fitting 12 can be integrally formed or detachably connected. For ease of cleaning, a detachable connection will be used as an example. Specifically, both ends of the flexible pipe are connected to the connecting pipe segment 2b of the first pipe fitting 11 and the first pipe 2 via an inner and outer sleeve design. This inner and outer sleeve design facilitates the connection between the first pipe fitting 11 and the second pipe fitting 12.

[0045] The first fitting 11 and the second fitting 12 can be connected by an interference fit. However, in this embodiment, as... Figure 3 and Figure 4As shown, the outer peripheral walls at both ends of the flexible tube are threadedly connected to the inner peripheral walls of the first fitting 11 and the connecting pipe section 2b, respectively. This improves the reliability of the connection between the first fitting 11 and the second fitting 12, reducing the risk of them detaching during use. Furthermore, it facilitates disassembly and assembly, and makes cleaning of the first fitting 11, the second fitting 12, and the first pipe 2 easy.

[0046] like Figure 3 and Figure 4 As shown, the aforementioned flexible pipe includes a flexible corrugated pipe 121 with a corrugated longitudinal section and a flexible body for supporting the flexible corrugated pipe 121. The flexible corrugated pipe 121 is sleeved around the flexible body, and the inner peripheral wall of the flexible corrugated pipe 121 abuts against the flexible body. This flexible pipe design can increase the sealing between the second pipe fitting 12 and the first pipe 2, as well as between the second pipe fitting 12 and the first pipe fitting 11, reducing the risk of leakage.

[0047] Furthermore, the flexible body is a spring 122, and a spiral channel 1211 is formed on the inner peripheral wall of the flexible corrugated pipe 121. The spiral channel 1211 extends spirally along the length of the flexible corrugated pipe 121, and the spring 122 is embedded in the spiral channel 1211. In this way, the sealing between the flexible pipe and the first pipe 2 and the first pipe fitting 11 can be further increased.

[0048] In addition, such as Figure 5 and Figure 6 As shown, a suction cup 3 is installed on the first pipe fitting 11, and the suction cup 3 has a cavity 30 that communicates with the first pipe fitting 11. The design of the suction cup 3 can create negative pressure in the cavity 30, which increases the negative pressure space, improves the suction force, and makes it easier to suck away foreign objects in the pipe to be unclogged (such as kitchen and bathroom drains).

[0049] In order to connect the suction cup 3 to the first tube 11, the suction cup 3 is provided with an insertion channel 31 for the first tube 11 to be inserted.

[0050] Furthermore, such as Figure 2 As shown, the first pipe fitting 11 includes a first connecting pipe section 111 and a second connecting pipe section 112 connected sequentially along its length. The first connecting pipe section 111 is sleeved on the outer periphery of the flexible pipe, and the inner diameter of the first connecting pipe section 111 is larger than the inner diameter of the second connecting pipe section 112. An anti-slip portion 1111 is formed on the outer peripheral wall of the first connecting pipe section 111. It can be understood that the first connecting pipe section 111 can serve as an operating part, and the anti-slip portion 1111 increases friction, making operation more convenient.

[0051] like Figure 1As shown, a plurality of anti-slip portions 1111 are distributed on the outer peripheral wall of the first connecting pipe section 111. The anti-slip portions 1111 can be grooves, bosses, anti-slip patterns, etc. In this embodiment, there are multiple anti-slip portions 1111, which are arranged at intervals along the circumference of the first connecting pipe section 111.

[0052] In this embodiment, such as Figure 5 and Figure 6 As shown, when installing the suction cup 3, the second connecting pipe section 112 and part of the first connecting pipe section 111 are both located within the aforementioned insertion channel 31.

[0053] The aforementioned cleaning device can be a vacuum cleaner, which creates negative pressure to suck foreign objects from the drain into the vacuum cleaner. It can also be a blower, which, when unclogging a sewer, blows air into the drain to force foreign objects out of the drain. Additionally, the cleaning device can be a flushing device, for example, through which water is passed into the drain to flush away the obstruction.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
