Technical Field

[0001] This utility model belongs to the technical field of vacuum cleaner accessories, and more specifically, it relates to a docking device for a vacuum cleaner dust bag. Background Technology

[0002] The docking device for vacuum cleaner dust bags is a key connecting component between the vacuum cleaner and the dust bag. Its core function is to achieve a tight connection between the two, ensuring that airflow can smoothly enter the dust bag during vacuuming, while preventing dust leakage, avoiding dust bag detachment, and facilitating user installation and replacement of the dust bag. However, the docking devices commonly used in vacuum cleaner dust bags cannot completely prevent dust in the dust bag from flowing back to the vacuum cleaner host or the external environment through the docking pipeline in specific scenarios such as when the machine is stopped, when emptying the dust bag, or when the machine is tilted, thereby causing secondary pollution or affecting the performance of the equipment. Therefore, a new type of docking device for vacuum cleaner dust bags is needed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a docking device for a vacuum cleaner dust bag, thereby solving the problem that existing vacuum cleaner dust bag docking devices are unable to completely prevent dust from flowing back into the dust bag.

[0005] A docking device for a vacuum cleaner dust bag includes a connecting tube A, a corrugated tube, and a movable tube;

[0006] The upper end of the connecting pipe A is provided with a fixed pipe, and the lower surface of the fixed pipe is fixedly connected to the upper surface of the connecting pipe A. The corrugated pipe is placed outside the lower end of the connecting pipe A, and the corrugated pipe is movably connected to the lower end of the connecting pipe A. The lower end of the corrugated pipe is connected to the connecting pipe B, and the upper end of the connecting pipe B is provided with a thread. The movable pipe is fitted on the outside of the connecting pipe B, and the upper end of the movable pipe is provided with a thread. The upper end of the movable pipe is threaded with the upper end of the connecting pipe B. The inner center end of the movable pipe is provided with a groove.

[0007] Furthermore, the connecting pipe A has two sets of connectors inside, and three sets of inclined baffles are connected to the inner side of each of the two sets of connectors, with the six sets of inclined baffles arranged in an alternating pattern.

[0008] Furthermore, a fixing plate is installed on the inner side of the lower end of the connecting pipe A, and a flat flexible tube is provided at the lower end of the fixing plate, and the flat flexible tube is inserted into the interior of the corrugated pipe.

[0009] Furthermore, a partition is fixedly connected to the outside of the connecting pipe B, and the partition is movably fitted into the groove at the center end of the inner side of the movable pipe.

[0010] Furthermore, a connecting pipe C is fixedly connected to the lower end of the movable tube, a sealing ring 1 is connected to the inner side of the lower end of the connecting pipe C, a groove is provided on the outer side of the lower end of the connecting pipe B, and a sealing ring 2 is connected in the groove on the outer side of the lower end of the connecting pipe B.

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a docking device for a vacuum cleaner dust bag, including a connecting pipe A2, a corrugated pipe 3, and a movable pipe 5;

[0025] The upper end of the connecting pipe A2 is provided with a fixed pipe 1, and the lower surface of the fixed pipe 1 is fixedly connected to the upper surface of the connecting pipe A2. The corrugated pipe 3 is placed on the outer side of the lower end of the connecting pipe A2, and the corrugated pipe 3 is movably connected to the outer side of the lower end of the connecting pipe A2. The lower end of the corrugated pipe 3 is connected to the connecting pipe B4, and the upper outer side of the connecting pipe B4 is provided with a thread. The movable pipe 5 is fitted on the outer side of the connecting pipe B4, and the upper inner side of the movable pipe 5 is provided with a thread. The upper inner thread of the movable pipe 5 engages with the upper outer thread of the connecting pipe B4. The inner center end of the movable pipe 5 is provided with a groove.

[0026] Among them, such as Figure 2 and Figure 3 As shown, the connecting pipe A2 has two sets of connectors 7 inside, and three sets of inclined baffles 8 are connected to the inner side of each of the two sets of connectors 7. The six sets of inclined baffles 8 are arranged in an alternating manner. When the vacuum cleaner is working, the airflow carrying dust can smoothly pass through the gaps between the inclined baffles 8 and enter the dust bag. When the vacuuming stops, the alternating inclined baffles can prevent the dust in the dust bag from flowing back into the vacuum cleaner pipe, reducing secondary pollution.

[0027] Among them, such as Figure 2 As shown, a fixing plate 9 is installed on the inner side of the lower end of the connecting pipe A2. A flat hose 10 is provided at the lower end of the fixing plate 9, and the flat hose 10 is inserted into the interior of the corrugated pipe 3. When backflow occurs, the flat hose 10 is subjected to reverse pressure and the two sides are pressed together, which hinders backflow and further enhances the anti-backflow effect.

[0028] Among them, such as Figure 4 and Figure 5As shown, a partition 11 is fixedly connected to the outer side of the connecting tube B4, and the partition 11 is movably fitted into the groove at the center end of the inner side of the movable tube 5. A connecting tube C6 is fixedly connected to the lower end of the movable tube 5, and a sealing ring 12 is connected to the inner side of the lower end of the connecting tube C6. A groove is provided on the outer side of the lower end of the connecting tube B4, and a sealing ring 13 is connected in the groove on the outer side of the lower end of the connecting tube B4. The dust bag interface is placed between the sealing ring 12 and the sealing ring 13. By rotating the movable tube 5, the connecting tube B4 and the movable tube 5 are threaded together. The sealing ring 12 and the sealing ring 13 cooperate to clamp and fix the dust bag interface, preventing dust leakage. At the same time, it avoids the dust bag from accidentally falling off due to airflow impact or vibration when the vacuum cleaner is working, thereby ensuring the stability and reliability of the vacuuming operation.

[0029] The specific usage and function of this embodiment are as follows:

[0030] like Figures 1 to 5 As shown, the device is connected to the vacuum cleaner body via a fixed pipe 1, serving as the fixed base for the entire docking device and ensuring stable assembly between the device and the vacuum cleaner. Utilizing the extensibility and flexibility of the corrugated pipe 3, the device can adapt to different dust bag installation positions or angles, improving docking flexibility. Each of the two sets of connectors 7 has three sets of inclined baffles 8 connected to its inner side, and the six sets of inclined baffles 8 are staggered. When the vacuum cleaner is working, the airflow carrying dust can smoothly pass through the gaps between the inclined baffles 8 and enter the dust bag; when vacuuming stops, the staggered inclined baffles can prevent the dust in the dust bag from flowing back into the vacuum cleaner pipe, reducing secondary pollution.
