Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum cleaner accessories, and relates to a conductive tube structure for a vacuum cleaner. Background Technology

[0002] In the cleaning industry, vacuum cleaners are widely used as a highly efficient cleaning tool. Vacuum cleaners typically consist of several parts, with the connection between the vacuum cleaner body and the floor brush being crucial for their proper functioning. This connection requires a structure consisting of a motor, coil, and conductive tubing.

[0003] The conductive tube structure of currently used vacuum cleaners mainly consists of an aluminum tube and a plastic connector. The aluminum tube acts as a protective sleeve for the cable, and the cable connecting to the plastic connector is placed inside. This design is intended to protect the cable from external environmental factors such as wear and tear, and impacts during use. Meanwhile, the plastic connector is responsible for connecting the cable to different parts of the vacuum cleaner.

[0004] In terms of connection method, the aluminum tube is snapped onto the plastic connector and secured with a screw. However, over long-term use, this connection method has gradually revealed some problems. Due to the properties of plastic, under prolonged stress and environmental influences, the plastic connector is prone to deformation and aging. Over time, the snap-fit ​​between the plastic connector and the aluminum tube will gradually loosen. Once loosening occurs, the connection between the cable inside the aluminum tube and the plastic connector becomes unstable, leading to poor contact.

[0005] A hissing sound is produced when the cable and connector have poor contact. This sound not only bothers users and affects the user experience, but more importantly, it indicates a potential malfunction in the vacuum cleaner's connection. Poor contact can lead to unstable current transmission, which in turn affects the normal operation of the motor. Utility Model Content

[0006] The purpose of this utility model is to provide a conductive tube structure for a vacuum cleaner. Without changing the original material, the connection structure between the aluminum tube and the plastic connector is improved to enhance the firmness of the connection between the two and solve the technical problem caused by loosening in the background art.

[0007] The objective of this utility model is achieved through the following technical solution:

Example

[0036] See also Figure 1 As shown, a conductive tube structure for a vacuum cleaner includes an outer tube 1, an inner tube, a body connector 2, and a floor brush connector 3. The outer tube 1 is made of aluminum, while the body connector 2 and the floor brush connector 3 are made of plastic. In this embodiment, although both the body connector 2 and the floor brush connector 3 are fixedly installed at both ends of the outer tube 1, their structures are different.

[0037] Combination Figures 2-4As shown, the body connector 2 has an inner tube connection portion 21 for inserting one end of the outer tube 1. The inner tube is placed inside the outer tube 1, with a channel for cable routing between them. The two ends of the inner tube are connected to the inner tube connection portion 21 on the body connector 2 and the inner tube connection portion 31 on the floor brush connector 3, respectively, thus isolating the airflow channel inside the inner tube from the cable routing channel outside the inner tube. Through the above structural design, the conductive tube structure provides both cable routing and airflow channel, and also provides rigid support, becoming the main support component of the vacuum cleaner.

[0038] The inner tube joint 21 has a first screw seat 22 that inserts into the outer tube 1, and the outer tube 1 is secured to the first screw seat 22 by a screw. The body connector 2 also has at least one second screw seat 23, with a gap between the second screw seat 23 and the inner tube joint 21 for the outer tube 1 to be inserted. The second screw seat 23 has a screw hole through which a screw passes to secure the outer tube 1 to the second screw seat 23. The first screw seat 22 and the second screw seat 23 are arranged in a circular array with the central axis of the inner tube joint 21 as a reference. In this embodiment, there is one second screw seat 23, which is distributed at a 180-degree angle to the first screw seat 22.

[0039] This invention, by adding a second screw seat 23 to the existing single first screw seat 22 for locking, provides a new locking position. Furthermore, the insertion of the outer tube 1 into the gap between the second screw seat 23 and the inner tube joint 21 also serves as a vertical limit, contributing to the stability of the outer tube 1 when inserted into the body connector 2. The screws lock and position the outer tube 1 and the body connector 2 from multiple angles and directions, enhancing the firmness of the connection and preventing loosening or detachment of the outer tube during use, thus ensuring the stability and reliability of the outer tube connection.

[0040] The body connector 2 has a first baffle 24, the inner tube joint 21 abuts against the first baffle 24, and a second screw seat 23 is disposed on the first baffle 24. The body connector 2 also has a second baffle 25, which is arranged parallel to the first baffle 24. A reinforcing rib is provided between the first baffle 24 and the second baffle 25 to enhance the structural strength of the body connector 2, enabling it to withstand greater external forces during use and preventing deformation and damage.

[0041] A protective cover 28 is also provided on the body connector 2. The first baffle 24 and the second baffle 25 respectively abut against the two ends of the protective cover 28, so that the protective cover 28 can be stably installed on the body connector 2. The protective cover 28 covers the first baffle 24, the second baffle 25 and the second screw seat 23, which on the one hand hides the internal structure and makes the overall body connector look more concise and beautiful; on the other hand, the protective cover can also protect the internal structure to a certain extent, prevent external factors such as dust and moisture from damaging it, extend the service life of the body connector, and ensure the stability and reliability of the connection of the outer tube 1.

[0042] Specifically, the inner tube joint 21, where the first screw seat 22 is located, has axially distributed protrusions 26. When the outer tube 1 is installed, it snaps onto the protrusions 26 and abuts against the first baffle 24, thus achieving initial positioning. Preferably, the upper end face of the protrusion 26 away from the first baffle is a guide slope. This guide slope plays a guiding role when installing the outer tube, allowing the outer tube 1 to snap onto the protrusions 26 more smoothly, improving installation efficiency and convenience.

[0043] In this embodiment, the protective cover 28 is assembled using an elastic element. Specifically, a spring piece 29 with one end suspended is provided on the body connector 2, and a pressing part 291 is provided on the suspended side of the spring piece 29. The protective cover 28 is provided with a clearance hole for the pressing part 291 to be inserted. With this design, the pressing part 291 is inserted into the clearance hole, which can securely fix the protective cover 28 to the body connector 2.

[0044] Furthermore, a spring clip limiting groove 27 is provided on the body joint between the first baffle 24 and the second baffle 25. The upper end of the spring clip limiting groove 27 is open, and a receiving cavity is formed inside for the spring clip to move downward. This design provides a stable installation position for the spring clip 29 and limits the range of motion of the spring clip 29, ensuring that it will not shift during operation.

[0045] When in use, if it is necessary to remove the protective cover 28 from the body connector 2, the pressing part 291 can be pressed down to disengage the spring piece 29 from the clearance hole of the protective cover 28. At this time, the protective cover 28 can be easily removed from the body connector 2 manually. This assembly method not only facilitates the installation and disassembly of the protective cover, but also provides convenience when it is necessary to maintain or repair the internal structure, while ensuring the stability and reliability of the protective cover during use.

[0046] Combination Figures 5-7As shown, the floor brush connector 3 has an inner tube connection portion 31 for inserting one end of the outer tube 1. The inner tube connection portion 31 has a first screw seat 32 that inserts into the outer tube 1, and the outer tube 1 and the first screw seat 32 are secured together by a screw. The floor brush connector 3 also has at least one second screw seat 33, with a gap between the second screw seat 33 and the inner tube connection portion 31 for inserting the outer tube 1. The second screw seat 33 has a screw hole through which a screw passes to secure the outer tube 1 to the second screw seat 33. The first screw seat 32 and the second screw seat 33 are arranged in a circular array with the central axis of the inner tube connection portion 31 as a reference. In this embodiment, there is one second screw seat 33, which is distributed at a 180-degree angle to the first screw seat 32.

[0047] This invention, by adding a second screw seat 33 to the existing single first screw seat 32 for locking, provides a new locking position. Furthermore, the insertion of the outer tube 1 into the gap between the second screw seat 33 and the inner tube joint 31 also serves as a vertical limit, contributing to the stability of the outer tube 1 when inserted into the floor brush connector 3. The screws lock and position the outer tube 1 and the floor brush connector 3 from multiple angles and directions, enhancing the firmness of the connection and preventing the outer tube from loosening or falling off during use, thus ensuring the stability and reliability of the outer tube connection.

[0048] The floor brush connector 3 has a first baffle 34, and the inner tube joint 31 abuts against the first baffle 34. The second screw seat 33 is disposed on the first baffle 34. The floor brush connector 3 also has a second baffle 35, which is arranged parallel to the first baffle 34. A reinforcing rib is provided between the first baffle 34 and the second baffle 35 to enhance the structural strength of the floor brush connector 3, enabling it to withstand greater external forces during use and preventing deformation and damage.

[0049] The floor brush connector 3 is also equipped with a protective cover 38. The first baffle 34 and the second baffle 35 respectively abut against the two ends of the protective cover 38, so that the protective cover 38 can be stably installed on the floor brush connector. The protective cover 38 covers the first baffle 34, the second baffle 35 and the second screw seat 33, which on the one hand hides the internal structure and makes the floor brush connector look more concise and beautiful; on the other hand, the protective cover can also protect the internal structure to a certain extent, preventing external factors such as dust and moisture from damaging it, extending the service life of the floor brush connector, and ensuring the stability and reliability of the external pipe connection.

[0050] Specifically, the inner tube joint 31, where the first screw seat 32 is located, has axially distributed protrusions 36. When the outer tube 1 is installed, it snaps onto the protrusions 36 and abuts against the first baffle 34, thus achieving initial positioning. Preferably, the upper end face of the protrusion 36 away from the first baffle is a guide slope. This guide slope plays a guiding role when installing the outer tube, allowing the outer tube 1 to snap onto the protrusions 36 more smoothly, improving installation efficiency and convenience.

[0051] In this embodiment, the protective cover 38 is assembled using screws. Specifically, a third screw seat 37 is provided on the floor brush connector 3 between the first baffle 34 and the second baffle 35. When the protective cover 38 needs to be installed, the screws are passed through the corresponding holes on the protective cover 38 and screwed into the third screw seat 37, thereby achieving a firm fixation of the protective cover 38. This assembly method is simple to operate, reliable in connection, and can effectively ensure that the protective cover 38 will not easily fall off during use, providing stable protection for the internal structure.

[0052] This invention improves the structure of the body connectors and floor brush connectors at both ends of the outer tube. Previously, the connection between the outer tube and the body connectors / floor brush connectors typically used a single-point locking method, which could lead to insufficient stability in practical use. To address this drawback, this invention adds new locking points to the original single-point locking mechanism, achieving multi-angle locking and positioning of the outer tube between the body connector and the floor brush connector. This design significantly enhances the strength of the connection, effectively preventing the outer tube from loosening or falling off, and ensuring the stability and reliability of the outer tube connection.
