Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0035] Please refer to Figures 1 to 5 The utility model provides a detachable roller brush, comprising a roller brush barrel 1 and a driving device 2.

[0036] Specifically, the roller brush drum 1 is detachably connected to the driving device 2, for example, the roller brush drum 1 is detachably mounted on the driving device 2. The driving device 2 has a driving portion 3 and an external connection portion 4 that are positioned relative to each other. The driving portion 3 is connected to the roller brush drum 1 and is used to drive the roller brush drum 1 to rotate. The external connection portion 4 is close to one end of the roller brush drum 1 and is used to rotatably connect to an external sweeping robot 5, so that the driving device 2 can use this end as a fulcrum to drive the roller brush drum 1 to rotate relative to the sweeping robot 5. A connecting member 6 is provided at the other end of the roller brush drum 1, one side of which is rotatably connected to the roller brush drum 1, and the other side is used for detachable and fixed connection with the sweeping robot 5.

[0037] It is understandable that during actual use, the drive device 2 can use one end of the roller brush barrel 1 as a fulcrum to drive the roller brush barrel 1 to rotate relative to the sweeping robot 5, thereby changing the position of the connecting member 6 located at the other end of the roller brush barrel 1. When the connecting member 6 moves with the roller brush barrel 1 to a position in contact with the sweeping robot 5, the connecting member 6 is fixedly connected to the sweeping robot 5. At this time, the installation of the roller brush barrel 1 is completed, and the drive unit 3 of the drive device 2 can drive the roller brush barrel 1 to rotate to perform normal cleaning operations. When disassembling the roller brush barrel 1, the roller brush barrel 1 is also driven by the drive device 2 to rotate relative to the sweeping robot 5, so that the connecting member 6 is separated from the sweeping robot 5. It can also be understood that the connecting member 6 is removed from the sweeping robot 5. At this time, the roller brush barrel 1 can be removed from the drive device 2 for cleaning or replacement. The present utility model realizes the rapid disassembly of the roller brush barrel 1, which improves the user experience.

[0038] In a specific embodiment, the connecting member 6 has an elastic engaging portion 61 on a side away from the roller brush 1 , and the elastic engaging portion 61 is used for engaging and connecting with the sweeping robot 5 .

[0039] For details, please refer to Figure 2 The elastic engaging portion 61 may include a spring piece 611 formed by extending outward from the upper portion of the connecting member 6. One side of the spring piece 611 has at least one engaging protrusion 612 for engaging with the sweeping robot 5. For example, the upper portion of the spring piece 611 may be integrally formed with the upper portion of the connecting member 6 body. The spring piece 611 continuously moves away from the connecting member 6 body as it extends outward, forming a Figure 2 The engaging protrusion 612 is located on the side of the elastic piece 611 away from the connecting member 6 body.

[0040] It will be appreciated that in this embodiment, the connecting member 6 is detachably fixedly connected to the sweeping robot 5 via a spring clip 611. Specifically, when the connecting member 6 moves with the roller brush drum 1 to a position in contact with the sweeping robot 5, the spring clip 611 engages with the sweeping robot 5 via the engaging protrusion 612, thereby securing the roller brush drum 1 in place. To remove the roller brush drum 1, the spring clip 611 can be pressed to release the engaging protrusion 612 on one side of the spring clip 611 from the sweeping robot 5. At this point, the drive device 2 can drive the roller brush drum 1 to rotate, moving it to a position convenient for removal, thereby facilitating its removal from the drive device 2.

[0041] In other embodiments, the connecting member 6 and the external sweeping robot 5 may be detachably fixedly connected by other means such as magnetic connection, which is not specifically limited here.

[0042] For further information, please refer to Figure 2 and Figure 4 The connecting member 6 may be provided with a through hole arranged along the axial direction of the roller brush drum 1, in which a rotating shaft 7 is fixedly arranged. A rotating shaft sleeve 8 is sleeved on the outer portion of the rotating shaft 7, and the rotating shaft sleeve 8 is fixedly connected to the roller brush drum 1. The connecting member 6 is rotatably connected to the roller brush drum 1 through the rotating shaft 7.

[0043] During use, when the roller brush drum 1 rotates, the roller brush drum 1 will drive the rotating shaft sleeve 8 to rotate synchronously with the rotating shaft 7 as the rotation center axis, but will not drive the connecting member 6 to move. The connecting member 6 always maintains a detachable fixed connection with the sweeping robot 5.

[0044] For example, the rotating shaft sleeve 8 and the roller brush drum 1 can be fixedly connected by plugging.

[0045] In a specific embodiment, please refer again to Figure 2 At least one connecting groove 11 is formed on the inner wall of the roller brush drum 1. The driving part 3 includes a driving shaft 31 and a connecting sleeve 32 fixedly connected to the driving shaft 31. Part of the connecting sleeve 32 is embedded in the connecting groove 11 and is used to drive the roller brush drum 1 to rotate by cooperating with the connecting groove 11 when the driving shaft 31 rotates.

[0046] It is understood that during use, the rotation of the drive shaft 31 will drive the connecting sleeve 32 to rotate synchronously. Since the connecting sleeve 32 is embedded in the connecting groove 11, it will push the groove wall of the connecting groove 11, thereby driving the rotation of the roller brush drum 1. For example, the setting direction of the connecting groove 11 can be the same as the axial direction of the roller brush drum 1. Therefore, when the roller brush drum 1 is mounted on the drive device 2, the drive device 2 enters the roller brush drum 1 from one end. When the connecting sleeve 32 is embedded in the connecting groove 11, it indicates that the connection between the roller brush drum 1 and the drive device 2 is complete.

[0047] Preferably, a soft rubber 14 can be sleeved on the outside of the drive shaft 31, so that the drive shaft 31 is connected to the connecting sleeve 32 through the soft rubber 14. The setting of the soft rubber 14 can reduce the noise of the rotation of the drive shaft 31, improve the user experience, and also play a certain buffering and damping role.

[0048] In a specific embodiment, the external connection part 4 includes a fixing part 41 and a rotating part 42 . The fixing part 41 is used to fix the connection to the external sweeping robot 5 . The rotating part 42 is rotatably connected to the fixing part 41 . The rotating part 42 is fixedly connected to the main body of the driving device 2 .

[0049] For example, please refer to Figure 2 and Figure 5 The fixing part 41 can be fixedly connected to the sweeping robot 5 by screws. A rotating shaft 9 is provided on the fixing part 41. The setting direction of the rotating shaft 9 can be the same as the horizontal radial direction of the roller brush barrel 1. The rotating part 42 is rotatably connected to the fixing part 41 through the rotating shaft 9.

[0050] Preferably, one or more elastic cotter pins 15 can be sleeved on the rotating shaft 9. The elastic cotter pins 15 are located between the rotating shaft 9 and the rotating member 42 to provide damping and reduce friction and wear between the rotating shaft 9 and the rotating member 42. It can also reduce the noise when the rotating member 42 rotates, thereby improving the user experience.

[0051] Furthermore, the fixing member 41 may have a limiting groove 10, and the two ends of the rotating shaft 9 described in the above embodiment may be fixedly connected to the inner walls on different sides of the limiting groove 10. The groove wall of the limiting groove 10 is divided into a first limiting portion 101 and a second limiting portion 102. The first limiting portion 101 and the second limiting portion 102 are used to limit the rotation of the rotating member 42 in different directions by abutting against the rotating member 42.

[0052] Specifically, when the rotating member 42 rotates about the rotating shaft 9 relative to the fixed member 41 toward the sweeping robot 5, the connecting member 6 moves with the roller brush drum 1 to a position of contact with the sweeping robot 5, and the roller brush drum 1 is installed in place. At this time, the rotating member 42 abuts against the first limit portion 101, thereby limiting further movement of the roller brush drum 1 to ensure the correct installation and stability of the roller brush drum 1. For example, when the roller brush drum 1 is correctly installed, it remains parallel to the horizontal plane.

[0053] When the roller brush drum 1 is to be removed, the rotating member 42 rotates about the rotating shaft 9 relative to the fixed member 41 in a direction away from the sweeping robot 5, thereby separating the connecting member 6 from the sweeping robot 5. After rotating to a certain extent, the rotating member 42 abuts the second limit portion 102, thereby restricting further movement of the roller brush drum 1. For example, when the rotating member 42 abuts the second limit portion 102, the roller brush drum 1 can be at a 45-degree angle to the horizontal plane, thereby facilitating removal of the roller brush drum 1 from the drive device 2.

[0054] In a specific embodiment, please refer to Figure 2 The roller brush drum 1 and the drive device 2 are connected via a bearing 13. Specifically, the inner wall of the roller brush drum 1 is connected to the outer ring of the bearing 13, and the drive device 2 is connected to the inner ring of the bearing 13. This allows the roller brush drum 1 to maintain smooth rotation and prevents the drive device 2 from interfering with the rotation of the roller brush drum 1. In embodiments where the external connection portion 4 includes a fixed member 41 and a rotating member 42, the inner ring of the bearing 13 can be connected to the rotating member 42.

[0055] In a specific embodiment, a plurality of ridges 12 are spaced apart on the inner wall of the roller brush drum 1, and heat dissipation channels are formed between adjacent ridges 12. Specifically, the extension direction of the ridges 12 may be the same as the axial direction of the roller brush drum 1, and the plurality of ridges 12 may be spaced apart along the circumference of the roller brush drum 1. It can be understood that the provision of the ridges 12 increases the distance between the drive device 2 and the inner wall of the roller brush drum 1, so that there is a gap therebetween, thus forming the aforementioned heat dissipation channel, which helps dissipate heat from the drive device 2 and can increase the service life of the drive device 2. Exemplarily, the drive device 2 may be a drive motor.

[0056] The present invention also provides a sweeping robot 5, comprising the detachable roller brush described in any of the above embodiments. Figure 1 For example, the bottom of the sweeping robot 5 may be provided with a receiving groove 51 for receiving the roller brush 1. One end wall of the receiving groove 51 is used for rotationally connecting with the external connection part 4, and the other end wall of the receiving groove 51 is used for detachable fixed connection with the connecting member 6. Thus, the sweeping robot 5 of the present invention can quickly disassemble its roller brush 1.

[0057] To sum up, the utility model provides a detachable roller brush and a sweeping robot 5 including the same, wherein the detachable roller brush provided is based on a rotatable connection between the external connection part 4 and the sweeping robot 5 and a detachable fixed connection between the connecting part 6 and the sweeping robot 5, so that when the roller brush barrel 1 is disassembled, it is only necessary to separate the connecting part 6 from the sweeping robot 5 and rotate the roller brush barrel 1 to a position convenient for disassembly, and then the roller brush barrel 1 can be quickly removed from the driving device 2 for cleaning or replacement. The replacement of the roller brush barrel 1 is convenient and efficient, and the user experience is good.
