Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0029] This utility model proposes a cleaning robot, referring to... Figure 1 and Figure 2 During the cleaning process, this cleaning robot can easily clean up linear objects such as hair, yarn, and other linear objects. Moreover, the cleaning roller brush 3 of the cleaning robot is not easily tangled with linear objects during the cleaning process. This not only completes the cleaning task reliably and ensures the cleaning effect, but also effectively prevents the cleaning roller brush 3 from getting tangled with linear objects, avoiding the phenomenon of the cleaning roller brush 3 failing to roll. This gives the cleaning robot an anti-tangling cleaning function.

[0030] The cleaning robots mentioned above can be self-propelled cleaning sweepers, handheld cleaning machines, or other cleaning equipment. There are no restrictions on the types of cleaning robots mentioned above.

[0031] The cleaning robot includes a cleaning robot body 1 and a cleaning component 2. The cleaning component 2 is mounted on the cleaning robot body 1. The cleaning component 2 includes a cleaning roller brush 3. One end of the cleaning roller brush 3 is connected to the drive component of the cleaning robot body 1, and the other end is suspended in the air. The cleaning roller brush 3 is inclined relative to the bottom horizontal plane of the cleaning robot body 1 that is parallel to the ground.

[0032] Based on the above scheme, by tilting the cleaning roller brush 3 onto the main body 1 of the cleaning robot, and with one end of the cleaning roller brush 3 suspended in the air, compared to the previous method where the cleaning components were horizontally mounted on the main body 1 of the cleaning robot, the cleaning roller brush 3 of this application has one end suspended in the air and the other end rotatably mounted on the cleaning robot. In this way, during the cleaning process of the ground, while ensuring reliable cleaning of the ground, when encountering hair waiting to be cleaned, the cleaning roller brush 3 can not only smoothly sweep away the hair, but also guide the hair to move towards the suspended end 32 of the cleaning roller brush 3. This effectively prevents the hair from getting tangled on the cleaning roller 34, so that the hair can be sucked away by the main body 1 of the cleaning robot, thereby realizing the anti-tangling cleaning function of the cleaning robot and improving the performance of the cleaning robot.

[0033] In conventional cleaning robots, both ends of the cleaning component are rotatably mounted on the main body 1. When cleaning linear objects such as hair, yarn, or other thin lines, the component, being parallel to the horizontal plane of the ground, is prone to entanglement. The linear objects easily become tangled in the middle or at both ends of the component. In particular, when the linear objects are tangled at the ends, the component is extremely prone to becoming jammed, causing it to become stuck or malfunction. This not only affects the cleaning effect but also damages the motor of the main body 1, potentially causing it to burn out. All of these issues are detrimental to the robot's usability.

[0034] In this embodiment, the cleaning roller brush 3 is connected to the main body 1 of the cleaning robot at only one end to ensure normal rotation. The other end of the cleaning roller brush 3 is suspended, meaning it is not connected to the main body 1. This creates a position on the cleaning roller brush 3 where linear objects can detach. When the cleaning roller brush 3 is cleaning hair, it effectively prevents hair from becoming entangled in the cleaning roller brush 3 as it rotates, thus minimizing the time hair remains on the brush. This ensures effective cleaning while preventing hair entanglement. This design significantly reduces the possibility of the cleaning roller brush 3 failing to rotate and the motor burning out, improving cleaning performance and user experience.

[0035] Reference Figures 1 to 6 The cleaning roller brush 3 has a connecting end 31 and a suspended end 32. The connecting end 31 is connected to the drive component of the cleaning robot body 1. The height of the connecting end 31 is higher than that of the suspended end 32 relative to the bottom horizontal plane of the cleaning robot body 1.

[0036] This configuration allows the cleaning roller brush 3 to be mounted at an angle on the main body 1 of the cleaning robot. Moreover, the cleaning roller brush 3 is only rotatably connected to the main body 1 of the cleaning robot via its connecting end 31, reducing the number of rotatable connection points of the cleaning roller brush 3 and thus reducing the possibility of the cleaning roller brush 3 being entangled by hair or other linear objects.

[0037] Furthermore, when the cleaning roller brush 3 is cleaning hair, since the height of the suspended end 32 is lower than that of the connecting end 31, the hair is more likely to move towards the suspended end 32 and away from the connecting end 31 during the cleaning rotation of the cleaning roller brush 3. Moreover, the suspended end 32 has no structural interference, so the hair can be easily detached from the cleaning roller brush 3, thereby preventing the cleaning roller brush 3 from being entangled by hair and greatly improving the cleaning effect of the cleaning roller brush 3.

[0038] It should be noted that the cleaning roller brush 3 is tilted and set on the main body 1 of the cleaning robot. The cleaning roller brush 3 still completes the cleaning of the objects to be cleaned on the ground, such as dust, debris, dirt and hair.

[0039] Furthermore, the connecting end 31 is connected to the drive component of the cleaning robot body 1 via the gearbox 6. This configuration allows the cleaning roller brush 3 to be detachably mounted on the cleaning robot body 1, reducing the difficulty of installing the cleaning roller brush 3 and also facilitating the adjustment of the tilt state of the cleaning roller brush 3.

[0040] The connecting end 31 can be configured as a block structure, such as a square shaft, a rectangular shaft, or a pentagonal adapter block. The gearbox 6 is provided with a socket for the connecting end 31 to be inserted. The connecting end 31 is limited to the socket, so that the connecting end 31 and the gearbox 6 are connected in a limited manner. The gearbox 6 is provided with multiple gear sets, and the gears are meshed and connected. The connecting end 31 is limited to the socket of the output gear of the gearbox 6. Under the action of the gearbox 6, the main body 1 of the cleaning robot can drive the cleaning roller brush 3 to rotate.

[0041] It is understood that gearbox 6 can be a micro gearbox 6, and gearbox 6 can adopt the gearbox 6 structure in existing related technologies, without specific limitations.

[0042] Reference Figures 1 to 6 The main body 1 of the cleaning robot is provided with a dust extraction port 11, and the cleaning roller brush 3 is provided with a cleaning part 33 for cleaning the ground. The dust extraction port 11 is located on one side of the axial direction of the cleaning roller brush 3.

[0043] The cleaning section 33 can clean the object to be cleaned, and at the same time, the dust extraction port 11 sucks up the dirt, so that the dirt can be removed from the cleaning roller brush 3. When cleaning hair and other dirt, the cleaning roller brush 3 cleans up the hair and moves the hair attached to the cleaning roller brush 3 towards the suspended end 32 and away from the connecting end 31. The dust extraction port 11 sucks up the hair, so that the hair can be removed from the cleaning roller brush 3 more easily. This greatly reduces the possibility of the cleaning roller brush 3 being entangled by hair, and reduces the possibility of the cleaning roller brush 3 being stuck due to hair and causing rotation failure. This improves the cleaning effect of the cleaning roller brush 3 and better enhances the user experience.

[0044] The cleaning trajectory of the cleaning section 33 is parallel to the ground. This means that even when tilted, all cleaning sections 33 on the cleaning roller brush 3 can clean the ground. This design ensures the cleaning performance of the cleaning roller brush 3. To ensure that the cleaning sections 33 can contact the ground, the cleaning roller brush 3 can be designed with a conical structure. Each cleaning section 33 is equipped with cleaning bristles 331. The length of the cleaning bristles 331 near the connecting end 31 is greater than the length of the cleaning bristles 331 near the suspended end 32. This ensures the reliability of the cleaning roller brush 3 in cleaning dirt from the ground, improving its cleaning reliability and stability, and enhancing the overall performance of the cleaning robot.

[0045] The dust extraction port 11 is correspondingly positioned to the suspended end 32 of the cleaning roller brush 3. When the cleaning roller brush 3 is tilted, it moves hair to the dust extraction port 11 during rotation. Under the action of suction, the hair is sucked into the dust extraction port 11 to collect it, preventing the cleaning roller brush 3 from being entangled in hair. This allows for more thorough cleaning of dirt on the ground, thereby improving the cleaning effect of the cleaning roller brush 3.

[0046] When the number of cleaning roller brushes 3 is set to one, the dust extraction port 11 is located at one end of the cleaning roller brush 3; when the number of cleaning roller brushes 3 is set to two, the two cleaning roller brushes 3 are set opposite each other, the suspended ends 32 of the two cleaning roller brushes 3 are set opposite each other and close to each other, and the dust extraction port 11 is set roughly corresponding to the position between the two cleaning roller brushes 3. In this way, the dust extraction port 11 can simultaneously absorb the hair of the cleaning roller brushes 3, reducing the possibility of the cleaning roller brushes 3 being entangled by hair.

[0047] When the cleaning roller brush 3 is configured as one, two, or even multiple, it provides more possibilities for the location of the dust extraction port 11. In other words, the structure of the cleaning roller brush 3 can be adaptively configured according to the design location of the dust extraction port 11, and the layout can be more reasonable based on the structural characteristics of the cleaning robot. In this embodiment of the application, a single cleaning roller brush 3 is used. This is only for illustrative purposes and does not limit the structure of the cleaning roller brush 3.

[0048] The cleaning roller brush 3 has a conical structure, and it forms an acute angle with the bottom horizontal plane of the cleaning robot body 1. It can be understood that the cleaning section 33 of the cleaning roller brush 3 is conical, with its radial dimension gradually increasing from the suspended end 32 to the connecting end 31; similarly, the length of the multiple cleaning strips 331 on the cleaning section 33 can also gradually increase from the suspended end 32 to the connecting end 31. This design ensures that the cleaning roller brush 3 can effectively clean dirt on the ground even when tilted, thus ensuring the cleaning effect of the cleaning robot.

[0049] Furthermore, the cleaning roller brush 3 is set at an acute angle to the bottom horizontal plane of the cleaning robot body 1, that is, the axis of the cleaning roller brush 3 is set at an acute angle to the bottom horizontal plane of the cleaning robot body 1. The angle between the cleaning roller brush 3 and the bottom horizontal plane of the cleaning robot body 1 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc. By limiting the angle between the cleaning roller brush 3 and the bottom horizontal plane of the cleaning robot body 1, the radial dimension of the cleaning part 33 of the cleaning roller brush 3 can be reasonably designed according to the structural space of the cleaning robot body 1, avoiding the size of the cleaning part 33 being too large or too small, thereby improving the applicability of the cleaning robot.

[0050] Reference Figures 1 to 6 The cleaning roller brush 3 includes a cleaning roller 34, on which multiple cleaning sections 33 are spirally arranged along its axial direction, and the multiple cleaning sections 33 are spaced apart along the circumferential direction of the cleaning roller 34. During the cleaning process, the cleaning roller brush 3 sweeps away dirt on the ground through the multiple cleaning sections 33 as it rolls, thus thoroughly cleaning the dirt on the ground and ensuring the cleaning effect of the cleaning roller brush 3 even when tilted.

[0051] Furthermore, multiple cleaning sections 33 are spaced apart in the circumferential direction of the cleaning roller 34. This helps prevent hair from getting tangled when cleaning linear objects such as hair, and also helps the hair move towards the suspended end 32. This further prevents the cleaning roller brush 3 from getting tangled in hair, improves the cleaning effect of the cleaning roller brush 3, and enhances the cleaning reliability of the cleaning roller brush 3, thereby improving the cleaning reliability and stability of the cleaning robot.

[0052] The cleaning section 33 can be configured as a rubber strip with multiple cleaning bristles 331 on it. The cleaning bristles 331 are used to clean dirt. The rubber strip can have cleaning bristles 331 on only one side, which reduces the number of cleaning bristles 331 while ensuring the floor is clean, and to some extent reduces the possibility of the cleaning roller brush 3 getting tangled in hair.

[0053] The cleaning roller 34 can be conical or cylindrical. The cleaning roller 34 serves to transmit power so that the cleaning unit 33 can rotate to clean and sweep away dirt on the ground.

[0054] The cleaning component 2 also includes a mounting shell 4, which is inclined relative to the bottom plane of the cleaning robot body 1. The mounting shell 4 has a receiving groove 41, and the dust extraction port 11 is connected to the receiving groove 41. The cleaning roller brush 3 is rotatably mounted in the receiving groove 41. The receiving groove 41 provides installation space for the cleaning roller brush 3, and also provides rotation space for the cleaning roller brush 3, allowing it to rotate. The mounting shell 4 is inclinedly mounted on the cleaning robot body 1 to adapt to the inclined state of the cleaning roller brush 3, ensuring that the cleaning roller brush 3 can rotate normally, while saving installation space for the mounting shell 4, reducing the space occupied by the mounting shell 4, and improving the structural compactness between the mounting shell 4 and the cleaning robot body 1.

[0055] During the rotation of the cleaning roller brush 3 and the suction process, the receiving groove 41 can easily clean and suck up dirt, thereby improving the cleaning effect of the cleaning robot. At the same time, under the action of suction, the cleaning roller brush 3 can more thoroughly clean the dirt on the ground, and the suction can also suck up hair, minimizing the possibility of the cleaning roller brush 3 being entangled in hair.

[0056] The receiving groove 41 can also constrain the rotation of the cleaning part 33 of the cleaning roller brush 3 within the receiving groove 41, preventing the cleaning part 33 from directly contacting the internal structure of the cleaning robot body 1, so that the cleaning roller brush 3 can more reliably clean the dirt on the ground.

[0057] The cleaning roller brush 3 also includes a fixed bracket 5 installed in the receiving groove 41. The cleaning roller brush 3 has a connecting end 31 and a suspended end 32. The connecting end 31 is rotatably connected to the fixed bracket 5, and the suspended end 32 is suspended in the opening of the receiving groove 41. The fixed bracket 5 provides axial support for the cleaning roller brush 3. This arrangement allows the cleaning roller brush 3 to be stably rotated and installed in the receiving groove 41, effectively preventing the cleaning roller brush 3 from falling off and improving the structural stability of the cleaning roller brush 3.

[0058] The fixed bracket 5 can be fixed to the wall of the receiving groove 41 with screws to ensure the stability of the fixed bracket 5.

[0059] The fixed bracket 5 has a through hole 51 for the connecting end 31 to pass through. The connecting end 31 has a limiting part 311, which engages with the hole edge of the through hole 51 to limit the cleaning roller brush 3. The connecting end 31 is connected to the drive component of the cleaning robot body 1 via the gearbox 6. The limiting part 311 limits the cleaning roller 34, so that when the cleaning roller 34 rotates to drive the cleaning part 33 to rotate, it can effectively limit the downward movement of the cleaning roller 34, so that the cleaning roller 34 can rotate stably in the receiving groove 41, thereby ensuring the cleaning reliability and effect of the cleaning roller brush 3.

[0060] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
