Description

Technical Field

[0001] This utility model belongs to the field of pipe dredging, specifically relating to a pipe dredging tool and pipe dredging device. Background Technology

[0002] Vegetable scraps, hair, toilet paper, and other residues can easily get into drains, causing blockages over time. This is especially true for kitchen drains, where grease tends to accumulate as people's living standards improve, exacerbating blockages.

[0003] Clogged drains cause significant inconvenience and can be cleared using drain cleaning devices. Existing drain cleaning devices typically use a drain spring in conjunction with various metal drain heads. During the cleaning process, the metal drain head rotates at high speed along with the spring, which can easily damage the pipes, especially bends. Furthermore, the metal drain head is ineffective at removing residue from the pipes, resulting in poor cleaning performance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pipe cleaner, which includes a cleaning spring and a cleaning head, wherein the cleaning head is made of a semi-flexible material; the cleaning head includes a cleaning handle and a plurality of cutting and scraping parts; wherein the cleaning handle is a hollow structure, surrounding the cleaning spring and connected to the cleaning spring; the plurality of cutting and scraping parts are evenly distributed around the cleaning handle in the circumferential direction; and each cutting and scraping part is spiral in the axial direction of the cleaning handle; a loading groove is formed between two adjacent cutting and scraping parts.

[0005] In some embodiments, the drain head further has a spiral groove that extends from one end of the drain head in a spiral direction to the other end of the drain head; the cutting portion is divided into multiple cutting segments by the spiral groove.

[0006] In some embodiments, the rotation direction of the spiral groove is the same as or opposite to the rotation direction of the spiral of the scraping portion.

[0007] In some embodiments, the ratio of the width of the spiral groove to the length of the cut segment is 0.8 to 1.2.

[0008] In some embodiments, the drain head further has a plurality of annular grooves, which are spaced apart along the length of the drain head; the cutting portion is divided into multiple cutting segments by the plurality of annular grooves.

[0009] In some embodiments, the number of the cutting portions is 3 to 8.

[0010] In some embodiments, the semi-flexible material is a thermoplastic elastomer or thermoplastic rubber.

[0011] In some embodiments, the length of the drain spring is greater than the length of the drain head, and both ends of the drain spring extend from both ends of the drain head.

[0012] In some embodiments, the length of the drain head is 40 to 60 centimeters, and the length of the drain spring is 50 to 70 centimeters.

[0013] On the other hand, the present invention provides a pipe dredging device, which includes the pipe dredging device described in any of the above claims.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a pipe cleaner that is used in conjunction with a pipe cleaning device. The pipe cleaning device drives the pipe cleaner to rotate. After the pipe cleaner enters the pipe, it cleans the dirt on the pipe wall through its cutting and scraping part. Since the cleaning head is made of a semi-flexible material, which has both a certain rigidity and strength, as well as flexibility and deformation ability, the cutting and scraping part will not damage the pipe wall during rotation. At the same time, the loading groove can accommodate the residue in the pipe, so that the residue is carried out of the pipe along with the cleaning head when it is pulled out, thereby improving the cleaning effect.

[0025] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0027] This utility model provides a drain cleaner 10, which includes a drain spring 1 and a drain head 20. The drain head 20 has a cutting and scraping part 3 on its surface, and a carrying groove 4 is formed between two adjacent cutting and scraping parts 3. When the kitchen drain pipe or other drainage pipe is blocked, the drain cleaner 10 can be connected to the drain cleaning device through the drain spring 1 for drain cleaning. Driven by the drain cleaning device, the drain head 20 rotates and moves forward in the pipe, which can break up or break through the blockage. The cutting and scraping parts 3 can clean the dirt on the pipe wall. Since the drain head 20 is made of a semi-flexible material, it will not damage the pipe. The carrying groove 4 can hold the residue in the pipe, so that the residue is carried out of the pipe along with the drain head 20, thereby improving the unblocking effect.

[0028] like Figure 1A , 1B As shown in Figure 1C, as an embodiment of the drain cleaner 10, the drain cleaner 10 includes a drain spring 1 and a drain head 20. The drain head 20 includes a drain handle 2 and a plurality of cutting and scraping parts 3. The drain handle 2 is a hollow structure with a through hole at the center of the hollow structure. The through hole is circular in shape and surrounds the drain spring 1 and is combined with the drain spring 1.

[0029] In this embodiment, as Figure 1CAs shown, multiple scraping parts 3 are evenly distributed around the periphery of the unclogging handle 2 along its circumferential direction; and each scraping part 3 is spiral-shaped along the axial direction of the unclogging handle 2, with a loading groove 4 formed between two adjacent scraping parts 3. During pipe unclogging, the scraping parts 3 can scrape off the dirt on the pipe wall during rotation, making the pipe less likely to be blocked again. Since the unclogging head 20 is made of semi-flexible material, it will not damage the pipe wall; the loading groove 4 can accommodate some residual blockages, and when the unclogging head 20 is pulled out, these residues will also be carried out of the pipe, thereby enhancing the pipe unclogging effect.

[0030] Semi-flexible materials are a class of materials that fall between rigid and flexible materials, possessing both a certain degree of rigidity and strength while exhibiting flexibility and deformability. Under low stress or small deformation, semi-flexible materials exhibit rigidity, maintaining shape and structural stability; under high stress or large deformation, they exhibit flexibility, absorbing energy and adapting to complex shapes. Therefore, a drain cleaner head 20 made of semi-flexible materials can effectively unclog pipes without damaging them.

[0031] In some embodiments, the drain head 20 is made of thermoplastic rubber material, which can maintain the overall rigid frame support and has the elasticity of rubber and the processability of thermoplastic plastic. It can be integrated with the drain spring 1 to make the drain head 20 less prone to damage. In some embodiments, the drain head 20 may also be made of thermoplastic elastomer material.

[0032] In some embodiments, such as Figure 2 As shown, the drain cleaner head 20 also has a spiral groove 5, which extends from one end of the drain cleaner head 20 in a spiral direction to the other end; the scraping part 3 is divided into multiple cutting segments 6 by the spiral groove 5. The drain cleaner head 20 can bend at the position of the spiral groove 5, allowing it to pass through the bend and unclog the blockage accumulated in the bend. When there are blockages such as hair in the pipe, for example, hair easily accumulates in the bathroom drain pipe and causes blockage, as the drain cleaner head 20 rotates, the hair will also become entangled in the carrying tray 4 or the spiral groove 5, and can then be carried out of the pipe along with the drain cleaner head 20.

[0033] In some embodiments, such as Figure 2 As shown, the rotation direction of the spiral line of the spiral groove 5 is the same as the rotation direction of the spiral line of the scraping part 3; in some embodiments, the rotation direction of the spiral line of the spiral groove 5 may also be opposite to the rotation direction of the spiral line of the scraping part 3.

[0034] In some embodiments, the ratio of the groove width of the spiral groove 5 to the length of the cut segment 6 is 0.8 to 1.2, making the unclogging head 20 easier to bend and facilitating manufacturing. For example, as Figure 3 As shown, in some embodiments, the ratio of the groove width d2 of the spiral groove 5 to the length d1 of the cutting segment 6 is 1.1.

[0035] In some embodiments, distinct from Figure 2 In the illustrated embodiment, the drain cleaner head 20 may have multiple annular grooves (not shown), which are spaced apart along the length of the drain cleaner head 20. The cutting and scraping portion 3 is divided into multiple cutting segments 6 by the multiple annular grooves. The drain cleaner head 20 can be bent at the annular grooves to unclog bends in the pipe. In some embodiments, the annular grooves in the middle portion of the drain cleaner head 20 are more densely distributed, while the annular grooves at both ends of the drain cleaner head 20 are more sparsely distributed, making it easier to bend.

[0036] In some embodiments, such as Figure 3 As shown, the length of the drain cleaning spring 1 is greater than the length of the drain cleaning head 20, and both ends of the drain cleaning spring 1 extend from both ends of the drain cleaning head 20. One end of the drain cleaning spring 1 can be connected to other drain cleaning components, which work together with the drain cleaning head 20 to unclog pipes and enhance the pipe unblocking effect. In some embodiments, one end of the drain cleaning spring 1 extends from one end of the drain cleaning head 20, and the other end is wrapped by the drain cleaning head 20. For example, the surface of the drain cleaning head 20 is conical, and one end of the drain cleaning spring 1 extends from the circular bottom portion of the drain cleaning head 20. During the pipe unblocking process, the conical top of the drain cleaning head 20 can more easily break through the blockage.

[0037] The dimensions of the drain cleaning spring, drain cleaning head 20, and their individual components can be determined according to the pipe diameter to fit different pipe models. Common drain pipe models include D50, D75, D90, and D110, with pipe diameters of 50 mm, 75 mm, 90 mm, and 110 mm, respectively.

[0038] In some embodiments, the number of scraping parts 3 can be 3 to 8. When the pipe diameter is small, the number of scraping parts 3 is small; when the pipe diameter is large, the number of scraping parts 3 is large. 3 to 8 scraping parts 3 can ensure both effective unblocking and allow the loading tank 4 to accommodate some of the residue. For example, as... Figure 4 As shown, the drain cleaner head 20, which is designed for pipes with a diameter of 50 mm, has three cutting and scraping sections 3; as shown... Figure 2 As shown, the drain cleaner head 20, which is designed for pipes with a diameter of 75 mm, has four cutting and scraping sections 3; Figure 5 As shown, the drain cleaner head 20, which is designed for pipes with a diameter of 90 mm, has 5 cutting and scraping sections 3; Figure 6 As shown, the drain cleaner head 20, which is designed for pipes with a diameter of 110 mm, has 6 cutting and scraping sections 3.

[0039] In some embodiments, the length of the drain head 20 is 40 to 60 cm, and the length of the drain spring 1 is 50 to 70 cm. Such a drain head 20 is easy to manufacture and achieves good unclogging results in practical use. For example, as... Figure 4 As shown, the drain cleaner head 20 is adapted to pipes with a diameter of 50 mm and has a length of 40 cm, while the drain cleaner spring 1 has a length of 50 cm; Figure 2 As shown, the drain cleaner head 20 is adapted to pipes with a diameter of 75 mm and has a length of 45 cm, while the drain cleaner spring 1 has a length of 55 cm; Figure 5 As shown, the drain cleaner head 20 is adapted to pipes with a diameter of 90 mm and has a length of 50 cm, while the drain cleaner spring 1 has a length of 60 cm; Figure 6 As shown, the drain cleaner 20 is adapted to a pipe with a diameter of 110 mm and has a length of 60 cm, while the drain cleaner spring 1 has a length of 70 cm.

[0040] In some embodiments, the groove width of the spiral groove 5 is 15 to 90 mm, allowing the unclogging head 20 to pass smoothly through the bend in the pipe. For example, as Figure 4 As shown, the drain cleaner head 20, which is adapted to pipes with a diameter of 50 mm, has a spiral groove 5 with a groove width of 25 mm; as Figure 3 As shown, the drain cleaner head 20, which is adapted to pipes with a diameter of 75 mm, has a groove width d2 of 35 mm in its spiral groove 5; as Figure 5 As shown, the drain cleaner head 20, which is adapted to pipes with a diameter of 90 mm, has a spiral groove 5 with a groove width of 40 mm; as Figure 6 As shown, the drain cleaner head 20 is adapted to pipes with a diameter of 110 mm, and its spiral groove 5 has a groove width of 50 mm.
