Description

Technical Field

[0001] This utility model relates to the field of vacuum pipeline cleaning technology, and in particular to a telescopic vacuum pipeline cleaning tool. Background Technology

[0002] Vacuum ducts are widely used in many fields such as industrial production, building ventilation, and scientific research experiments. Over time, a large amount of dust, dirt, and various impurities accumulate on the inner walls of the ducts. These deposits not only affect the normal operating efficiency of the vacuum ducts but may also damage the systems they serve. Therefore, efficient cleaning of vacuum ducts is crucial. In existing vacuum duct cleaning technologies, manual handheld operation is commonly used, utilizing the length of a long pole to reach deep into the duct and relying on the friction between the bristles and the inner wall of the duct for cleaning.

[0003] An existing pipe cleaning tool with authorized publication number CN222710393U includes a push rod. A mounting rod is detachably mounted on the top of the push rod. The top of the mounting rod is arc-shaped, and a mounting block is fixedly connected to the surface of the mounting rod. A groove is formed on the lower surface of the mounting block, and a rotating groove is formed on the inner wall of the groove. A rotating rod is rotatably connected to the inner wall of the rotating groove via a bearing. A connecting block is fixedly connected to the surface of the rotating rod, and a fan-shaped scraper is fixedly connected to the surface of the connecting block. When the mounting rod is pushed into the pipe, the fan-shaped scraper rotates when it encounters debris, pushing the mounting rod deeper into the pipe. After pulling the mounting rod out, the debris in the pipe obstructs the return movement of the fan-shaped scraper, causing it to open under the resistance. Continuing to pull the mounting rod with the push rod, the fan-shaped scraper can then scrape out the debris from the pipe, facilitating pipe cleaning.

[0004] Regarding the aforementioned technologies, the existing vacuum pipe cleaning tools have the following drawbacks: traditional long-handled cleaning brushes are difficult to adapt to pipes of different diameters. When the pipe diameter is large, the bristles cannot fully cover and closely adhere to the inner wall of the pipe, resulting in a significant reduction in cleaning effectiveness. For pipes with smaller diameters, the long handle has poor operational flexibility and is prone to damaging the pipe. Therefore, this utility model provides a telescopic vacuum pipe cleaning tool.

The sidewall of the extension tube has a movable groove, and the movable rod slides inside the movable groove. The movable groove has multiple locking holes that are adapted to the locking block.

[0012] Preferably, the bottom of the storage tube is rotatably connected to a fixed shell, and a second motor is fixedly connected inside the fixed shell. The output end of the second motor is fixedly connected to the bottom of the storage tube.

[0013] In summary, the technical effects and advantages of this utility model are as follows: The internal expansion component allows the movable frame to tightly adhere the brush plate to the inner walls of pipes of different sizes. A first motor powers the rotating disc, which in turn limits the movable frame via a limiting groove, enabling it to achieve a specific movement trajectory. This ensures precise brush plate contact regardless of whether the pipe is narrow or wide, guaranteeing effective cleaning of every inner wall area and preventing dirt build-up due to poor fit. This comprehensively improves pipe cleanliness and enhances the versatility and adaptability of the cleaning tool. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: Reference Figure 1-5The telescopic vacuum pipe cleaning tool shown includes an extension tube 1, whose length can be flexibly adjusted to reach pipes at different locations. An extension shell 2 is fixedly connected to the top of the extension tube 1. The extension shell 2 protects the internal structure, provides installation space, and connects other components, providing a stable place for the internal expansion assembly. A fixed frame 9 is fixedly connected inside the extension shell 2. The fixed frame 9 supports and positions components such as the rotating disk 12 in the internal expansion assembly, ensuring the relative position stability of each component during operation and preventing shaking and displacement. The internal expansion assembly is located inside the fixed frame 9. The internal expansion assembly includes a rotating disk 12 located inside the fixed frame 9. The rotating disk 12, through its own rotation, guides the moving frame 10 to move along a specific trajectory using a limiting groove 14, thereby adjusting the position of the brush plate 3. The limiting groove 14 inside the rotating disk 12 determines the movement path of the moving frame 10, ensuring that the moving frame 10 can move smoothly and accurately. The fixed frame 9 is equipped with a movable frame 10, which slides inside the limiting groove 14 to receive the power transmitted by the rotating disk 12 and convert it into its own linear movement. The movable frame 10 passes through the fixed frame 9 and slides inside the fixed frame 9. This through and sliding design allows the movable frame 10 to work stably under the constraint of the fixed frame 9 and prevents it from deviating from the predetermined movement trajectory. One end of the movable frame 10 is fixedly connected to a brush plate 3. The movable frame 10 transmits its own movement to the brush plate 3, so that the brush plate 3 can flexibly move closer to or away from the center of the pipe according to the change of the pipe diameter, thereby closely fitting the inner wall of pipes of different diameters and achieving efficient cleaning.

[0020] Example 2: Reference Figure 1-5Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a first motor 11 is fixedly connected inside the extension shell 2. The first motor 11 provides power, and its output end is fixedly connected to the side wall of the rotating disk 12. After starting, it can drive the rotating disk 12 to rotate. A storage tube 8 is slidably connected to the side wall of the extension tube 1. The storage tube 8 is used to store the extension tube 1, facilitating the storage and carrying of tools, and also provides support when the extension tube 1 is extended. A liquid storage tank 6 is fixedly connected to the side wall of the storage tube 8. The liquid storage tank 6 is used to store cleaning fluid, providing the necessary cleaning medium for pipe cleaning. The bottom of the liquid storage tank 6 is fixedly connected to an outlet pipe 15, which is responsible for drawing out the cleaning liquid in the liquid storage tank 6. The outlet pipe 15 passes through the receiving pipe 8, and one end of the outlet pipe 15 is fixedly connected to a connecting distribution pipe 16. The distribution pipe 16 can evenly distribute the cleaning liquid to each spray head 4, ensuring that the cleaning liquid covers a wider area of ​​the inner wall of the pipe. The outlet end of the distribution pipe 16 passes through the extension pipe 1, and a spray head 4 is provided at the outlet end of the distribution pipe 16. The spray head 4 is used to spray the cleaning liquid onto the inner wall of the pipe to soften and decompose dirt and improve the cleaning effect. The side wall of the storage tube 8 is fixedly connected with two pairs of fixing blocks 21. The fixing blocks 21 provide a base for the installation and sliding of the squeezing blocks 17. The squeezing blocks 17 are slidably connected inside the nearest pair of fixing blocks 21. The squeezing blocks 17 can slide inside the fixing blocks 21 under the action of external force. The same spring 20 is fixedly connected between the nearest pair of squeezing blocks 17. When the squeezing blocks 17 are not subjected to external force, the spring 20 can restore them to their initial position. Each side wall of the extrusion block 17 is fixedly connected to a moving rod 13. The moving rod 13 moves with the extrusion block 17, transmitting the displacement of the extrusion block 17. Each side wall of the moving rod 13 is fixedly connected to a locking block 18. The locking block 18 is used to cooperate with the locking hole 19 on the extension tube 1 to fix the relative position of the extension tube 1 and the receiving tube 8. The side wall of the extension tube 1 is provided with a moving groove 5. The moving rod 13 slides inside the moving groove 5. The moving groove 5 provides a sliding track for the moving rod 13 and restricts its movement direction. The moving groove 5 is provided with multiple locking holes 19 that are adapted to the locking block 18. The multiple locking holes 19 can fix the extension tube 1 and the receiving tube 8 at different positions to adapt to the cleaning of pipes with different length requirements. The bottom of the collection tube 8 is rotatably connected to a fixed shell 7. The fixed shell 7 is used to support the collection tube 8 and, in cooperation with the second motor 22, provides rotational power to the collection tube 8. The second motor 22 is fixedly connected inside the fixed shell 7. The second motor 22 is used to output power, and its output end is fixedly connected to the bottom of the collection tube 8. After starting, it drives the collection tube 8 and connected components to rotate, thereby achieving all-round cleaning of the inner wall of the pipe.

[0021] The working principle of this utility is as follows: When using this cleaning tool, first squeeze the squeezing block 17 to compress the spring 20, causing the locking block 18 to disengage from the locking hole 19, allowing the extension tube 1 to extend from the receiving tube 8. After extending to the specific part of the pipe that needs to be cleaned, release the squeezing block 17, the spring 20 returns to its original state, and the locking block 18 engages with another locking hole 19 again, keeping the extension tube 1 and the receiving tube 8 stable. At this time, start the first motor 11, which drives the rotating disk 12 to rotate, causing the moving frame 10 to move along the limiting groove 14, so that the brush plate 3 can be in close contact with the inner wall of the pipe to be cleaned. Then, use the water pump to spray the cleaning liquid in the storage tank 6 through the distribution pipe 16 onto the inner wall of the pipe from the spray head 4. Start the second motor 22, which causes the entire device to rotate, and the brush plate 3 cleans the inner wall of the pipe.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
