The driving member 21 is used to drive the brush head 22 to move relative to the outer wall of the dust bag 13 to clean the outer wall of the dust bag 13.
[0031] The utility model provides a dust recovery device that is easy to clean. By setting the dust removal component 1 and the cleaning component 2 and other components, during use, the dust-containing gas can be first sucked into the recovery chamber 114 through the fan 12, and then through the filtering effect of the dust bag 13, larger particles of dust fall back to the recovery channel 113, and some smaller particles of dust adhere to the outer wall of the dust bag 13, and the filtered airflow is discharged through the second opening 112. After long-term use, the outer wall of the dust bag 13 will be partially blocked. Therefore, the dust recovery work is stopped first, and then the brush head 22 is driven by the driving member 21 to move relative to the outer wall of the dust bag 13 to clean the outer wall of the dust bag 13. After cleaning, dust can continue to be recovered; the utility model is provided with the above-mentioned structure. When it is necessary to improve the dust removal efficiency of the recovery dust removal device, it is not necessary to disassemble the dust bag 13. Such operation will reduce the workload of the staff, and the cleaning efficiency is high, which can meet the actual production needs.

The brush 222 includes a rotating member 2221, a fixed disk 2222, and a plurality of groups of bristles 2223. One end of the rotating member 2221 is connected to the connecting frame 221, and the other end is connected to the fixed disk 2222. The plurality of groups of bristles 2223 are arranged on the fixed disk 2222 and are staggered with each other. The plurality of groups of bristles 2223 contact the outer wall of the dust bag 13. The rotating member 2221 is used to drive the fixed disk 2222 and the plurality of groups of bristles 2223 to rotate synchronously to clean the outer wall of the dust bag 13. In actual applications, when the outer wall of the dust bag 13 needs to be cleaned, the driving member 21 can be used to drive the brush head 22 to move linearly in the vertical direction. At the same time, the rotating member 2221 drives the fixed plate 2222 and multiple groups of bristles 2223 to rotate synchronously to provide continuous and efficient cleaning of the outer wall of the dust bag 13.
[0036] In order to facilitate the cleaning of the outer wall of the dust bag 13, the connecting frame 221 encloses a cleaning space for covering the outer side of the dust bag 13.

The vibration ring 231 is provided with multiple groups, and the multiple groups of vibration rings 231 are sleeved on the outer side of the dust bag 13 at intervals in the vertical direction. In actual applications, the brush head 22 is first driven by the driving member 21 to move relative to the outer wall of the dust bag 13 to clean the outer wall of the dust bag 13. After cleaning, a small amount of dust will be lightly attached to the outer wall of the dust bag 13. Then, the vibration unit 232 is used to drive the vibration ring 231 to move, so as to drive the dust bag 13 to vibrate, so as to shake the small amount of dust lightly attached to the outer wall of the dust bag 13 into the recovery channel 113. After cleaning, the dust can continue to be recovered.
[0039] Special note: The driving member 21 drives the brush head 22 to clean the outer wall of the dust bag 13, which does not interfere with the use of the vibrating member 23. Preferably, the driving member 21 can first drive the brush head 22 to clean the outer wall of the dust bag 13, and then the driving member 21 and the brush head 22 are restored to the initial positions, and then the dust bag 13 is driven to vibrate by the vibrating member 23; wherein, the vibrating ring 231 is sleeved on the outer wall of the dust bag 13, when the driving member 21 drives the brush head 22 to clean the outer wall of the dust bag 13, the vibrating ring 231 and the vibration unit 232 are disconnected, and when the dust bag 13 needs to be driven to vibrate by the vibrating member 23, the vibrating parts of the vibrating ring 231 and the vibration unit 232 are connected to each other.
