However, in actual use, as time goes by, the rolling brush will gradually wear out due to continuous friction with the ground, and its diameter will also correspondingly decrease. In this way, the cleaning ability of the rolling brush will decrease. However, the position of the rolling brush of the cleaning device is usually fixed, so in order to restore the cleaning ability of the cleaning device, the only way is to replace the new rolling brush, which increases the use and maintenance cost of the user.

Whether it encounters protrusions, depressions or different material ground, the cleaning effect can be effectively guaranteed. At the same time, by reliably ensuring the interference amount of the roll brush and the surface to be cleaned, the overall performance of the cleaning equipment is improved. Users do not need to frequently pay attention to the wear condition and cleaning effect of the roll brush during use, greatly improving the practicality and convenience of the cleaning equipment, and enhancing the user's use experience.

[0040] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0041] In conjunction with Figures 1 to 6 The embodiments of the first aspect of the present application provide a rolling brush assembly, the embodiments of the second aspect of the present application provide a cleaning device 7, and the embodiments of the third aspect of the present application provide a cleaning system.

[0042] Among them, the rolling brush assembly is used for the cleaning device 7, and the cleaning device 7 can be a sweeping robot, a mopping robot, a sweeping and mopping integrated machine, or other cleaning device 7 that meets the requirements.

[0043] Specifically, the cleaning device 7 includes but is not limited to a machine body, a cleaning system, a driving system, etc. The above-mentioned systems are coordinated with each other, so that the cleaning device 7 can move autonomously to realize the cleaning function. The functional elements constituting the above-mentioned systems in the cleaning device 7 are integrally arranged in the machine body. It can be understood that the cleaning device 7 can be a self-moving cleaning device 7, wherein the self-moving cleaning device 7 is a device that automatically performs cleaning operations in a certain to-be-cleaned area without user operation.

[0044] The cleaning system includes a base station, which is used in cooperation with the cleaning device.

[0045] Specifically, when the cleaning device 7 starts to work, the cleaning device 7 starts from the base station to perform a cleaning task. When the cleaning device 7 completes the cleaning task or other conditions that need to suspend the cleaning task, the cleaning device 7 can return to the base station to charge or other operations, such as water replenishment, and / or washing, and / or dust collection, etc.

[0046] The rolling brush assembly provided by the embodiment of the first aspect of the application includes a floating support 1 and a fixed support 2. The rolling brush body 6 is rotatably arranged on the floating support 1. The fixed support 2 is detachably arranged on the cleaning device 7 and movably connected with the floating support 1 through a floating assembly 3. The floating assembly 3 is used to apply a force to the floating support 1 in the direction of the to-be-cleaned surface, so that the rolling brush body 6 is always attached to the to-be-cleaned surface.

[0047] It should be noted that in the present application, as the diameter of the rolling brush body 6 decreases due to wear during use, the floating assembly 3 can apply a force to the floating support 1 in the direction of the to-be-cleaned surface, so that the rolling brush body 6 is always attached to the to-be-cleaned surface. In this way, it can ensure that the rolling brush body 6 can maintain good cleaning effect under different degrees of wear, without the need to immediately replace a new rolling brush due to wear of the rolling brush body 6, thereby reducing the use and maintenance cost of the user. At the same time, it can adapt to various to-be-cleaned surfaces with different flatness. For uneven to-be-cleaned surfaces, the floating assembly 3 can adjust the attachment degree of the rolling brush body 6 to the to-be-cleaned surface according to the actual situation, so as to ensure effective cleaning under complex to-be-cleaned surface conditions. At the same time, since the attachment degree of the rolling brush body 6 to the to-be-cleaned surface can be automatically adjusted, the cleaning device 7 can also maintain relatively stable cleaning performance during long-term use, and will not have a large decrease in cleaning ability due to wear of the rolling brush body 6.

[0048] The to-be-cleaned surface can be a ground, a carpet, etc.

[0049] The rolling brush body 6 can have a ring structure and be sleeved on the floating support 1.

[0050] Specifically, as an embodiment, the floating support 1 is of a split structure, and the floating support 1 can be split into several parts. When the rolling brush body 6 is installed, a part of the rolling brush body 6 can be sleeved on one split support first, and then the rolling brush body 6 is combined with other split supports to complete the installation of the rolling brush body 6. As another embodiment, the floating support 1 is of an integral structure, and the floating support 1 has an installation side. The rolling brush body 6 is detachably wound on the floating support 1 from the installation side of the floating support 1.

[0051] In actual application, the rolling brush body 6 can rotate. When the cleaning device 7 is started, the driving system transmits power to the rolling brush body 6 to make it rotate at a specific speed and direction. The rotating movement of the rolling brush body 6 can effectively roll the dust, debris and the like on the surface to be cleaned into the cleaning device 7, achieving high cleaning efficiency.

[0052] Specifically, the rolling brush body 6 can be rotatably arranged on the floating support 1 by bearing connection, sleeve connection, gear transmission, belt transmission, magnetic coupling and the like. For example, the rolling brush body 6 and the floating support 1 are bearing connected, that is, a high-precision bearing is installed on the floating support 1, and the both end shafts of the rolling brush body 6 are inserted into the inner ring of the bearing. The rolling brush body 6 and the floating support 1 are sleeve connected, that is, a sleeve is fixedly installed on the floating support 1, and the both end shafts of the rolling brush body 6 are inserted into the sleeve. The inner diameter of the sleeve is slightly larger than the diameter of the shaft of the rolling brush body 6, so that the rolling brush body 6 can freely rotate relative to the sleeve. The rolling brush body 6 and the floating support 1 are gear transmitted, that is, a gear set is arranged on the floating support 1, one end shaft of the rolling brush body 6 is connected with one gear, and the other gears are driven to rotate by the motor, so as to drive the gear on the rolling brush body 6 to rotate and realize the rotation of the rolling brush body 6. The rolling brush body 6 and the floating support 1 are belt transmitted, that is, a belt pulley is installed on the floating support 1, and one end shaft of the rolling brush body 6 is also connected with a belt pulley. The two belt pulleys are connected by a belt. The motor drives one belt pulley to rotate, and the belt drives the belt pulley on the rolling brush body 6 to rotate, so as to make the rolling brush body 6 rotate. The rolling brush body 6 and the floating support 1 are magnetically coupled, that is, a magnetic component is installed on the floating support 1, and one end shaft of the rolling brush body 6 is installed with a magnetic element which is attracted to the magnetic component. When the motor drives the magnetic component to rotate, the magnetic element on the rolling brush body 6 is driven to rotate by magnetic coupling, so as to make the rolling brush body 6 rotate.

[0053] The floating support 1 is located at the bottom of the cleaning device 7, and the cleaning device 7 further has a fixed support 2 at the bottom. The fixed support 2 is movably connected with the floating support 1, so that the floating support 1 can move up and down relative to the fixed support 2.

[0054] Specifically, the floating support 1 is movably connected to the fixed support 2 via a floating component 3. The floating component 3 can be an elastic structure, a cylinder linkage structure, etc. It can be understood that when the floating component 3 is an elastic structure, it can be a spring or an elastic rubber block. One end of the elastic structure is connected to the fixed support 2, and the other end is connected to the floating support 1. The elastic structure can be compressed and extended according to actual conditions, thereby adjusting the position of the floating support 1 so that the roller brush body 6 always remains in contact with the surface to be cleaned. When the floating component 3 is a cylinder linkage structure, the cylinder body is connected to the fixed support 2, and the piston rod of the cylinder is connected to the floating support 1. By adjusting the air pressure inside the cylinder, the extension length of the piston rod can be controlled, thereby adjusting the position of the floating support 1.

[0055] The fixed bracket 2 is detachably mounted on the cleaning equipment 7, specifically, the end of the fixed bracket 2 away from the floating bracket 1 is detachably connected to the main body of the cleaning equipment 7.

[0056] Specifically, the fixed bracket 2 has a snap-fit ​​structure at the end away from the floating bracket 1, and the main body of the cleaning equipment 7 has a mating structure. The snap-fit ​​structure and the mating structure engage to securely install the fixed bracket 2 onto the main body of the cleaning equipment 7. Furthermore, when maintenance, cleaning, or replacement of the roller brush body 6 is required, the user can easily remove the fixed bracket 2 from the main body.

[0057] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figures 1 to 5 As shown, the floating component 3 includes a rotating connector 31 and an elastic drive component 32. The floating support 1 is rotatably connected to the fixed support 2 via the rotating connector 31. The elastic drive component 32 is connected to the floating support 1 and drives the floating support 1 to rotate around the rotating connector 31. Therefore, the angle and position of the floating support 1 can be automatically adjusted according to the flatness of the surface to be cleaned and the wear condition of the roller brush body 6, ensuring that the roller brush body 6 is always in close contact with the surface to be cleaned. Whether it is the unevenness of the surface to be cleaned or the change in the diameter of the roller brush body 6, it can be compensated in time by the action of the elastic drive component 32, thereby improving the cleaning effect. At the same time, the elastic drive component 32 has a buffering effect, which can reduce the impact force on the roller brush body 6 during operation and reduce the wear degree of the roller brush body 6 and other parts of the cleaning equipment 7. Meanwhile, the rotation function of the rotating connector 31 can also prevent the roller brush body 6 from experiencing excessive resistance when encountering obstacles, reducing the risk of damage.

[0058] Further, the rotating connection 31 enables the floating bracket 1 to rotate around the rotating connection 31, increasing the flexibility of the floating bracket 1. This enables the cleaning device 7 to better adapt to various complex cleaning scenarios, such as corners, edges of furniture, etc. In these areas, the cleaning device 7 can adjust the position of the roller brush body 6 through the rotation of the floating bracket 1, achieving more comprehensive cleaning.

[0059] In this embodiment, the rotating connection 31 serves as a connection between the floating bracket 1 and the fixed bracket 2 in the roller brush assembly, and allows the floating bracket 1 to rotate relative to the fixed bracket 2. For example, the rotating connection 31 can be a rotating shaft. The floating bracket 1 is connected to the fixed bracket 2 through the rotating shaft, and when the cleaning device 7 encounters different terrains or obstacles during operation, the floating bracket 1 can rotate by a certain angle around the rotating shaft, thereby better adapting to changes in the surface to be cleaned.

[0060] In this embodiment, the elastic driving member 32 is connected to the floating bracket 1, and its main function is to provide driving force for the floating bracket 1, enabling the floating bracket 1 to rotate around the rotating connection 31.

[0061] Specifically, the elastic driving member 32 has elastic properties and can produce different degrees of elastic deformation under different circumstances. When the roller brush body 6 encounters uneven surfaces to be cleaned or is subjected to external forces during operation, the elastic driving member 32 can be compressed or stretched according to the actual situation. For example, the elastic driving member 32 can be a spring or elastic rubber, etc. When the surface to be cleaned has a protrusion, the floating bracket 1 is subjected to an upward force, and the elastic driving member 32 is compressed, thereby causing the floating bracket 1 to rotate upward by a certain angle to ensure the adhesion of the roller brush body 6 to the surface to be cleaned; when the surface to be cleaned has a depression or the diameter of the roller brush body 6 decreases, the elastic driving member 32 is stretched, pushing the floating bracket 1 to rotate downward, also ensuring the close contact of the roller brush body 6 with the surface to be cleaned.

[0062] In some possible implementation embodiments disclosed in the present application, at least one segment of the rotating path of the floating bracket 1 is in a direction that reduces the distance between the floating bracket 1 and the surface to be cleaned. In this way, the roller brush body 6 can be ensured to adhere more closely to the surface to be cleaned. During cleaning, the contact pressure of the roller brush body 6 with the surface to be cleaned increases, thereby enabling dust, debris, etc. to be more effectively rolled into the cleaning device 7, improving the cleaning effect.

[0063] In this embodiment, the floating bracket 1 is not fixed but can move within a certain range, and the trajectory of its movement constitutes the rotating path.

[0064] Specifically, in the embodiment, the elastic potential energy of the elastic driving member 32 is released to drive the floating support 1 to rotate along the first direction towards the surface to be cleaned. The first direction can be downward or a certain angle inclined downward, so that the floating support 1 rotating along the first direction can drive the roller brush body 6 to be closer to the surface to be cleaned and interfere with the surface to be cleaned.

[0065] In some possible implementation embodiments disclosed in the present application, the axes of the two rotary connecting members 31 coincide when the first end and the second end of the floating support 1 are both rotationally connected to the fixed support 2 through the rotary connecting members 31. Thus, the forces on the two ends of the floating support 1 are more uniform during rotation, and there is no deflection torque due to the non-coincidence of the axes of the two rotary connecting members 31, thereby ensuring that the floating support 1 can maintain a stable posture in various working states. At the same time, uniform stress and stable rotation can reduce the wear of the rotary connecting members 31 and the connecting parts of the floating support 1 and the fixed support 2. The service life of the components is prolonged, and the maintenance cost is reduced.

[0066] Further, for the elastic driving member 32, the floating support 1 can be more effectively driven to rotate around the coincident axes, thereby achieving precise control of the position of the floating support 1. At the same time, precise rotation control enables the roller brush body 6 to always maintain the best fit state with the surface to be cleaned, whether on a flat surface to be cleaned or in an uneven area, thereby effectively improving the cleaning performance of the cleaning device 7.

[0067] The floating support 1 can be in a strip shape or have a certain length, and has two ends, i.e., a first end and a second end.

[0068] Specifically, the first end and the second end of the floating support 1 can be respectively provided with rotary connecting members 31 to connect the fixed support 2 and enable the floating support 1 to rotate relative to the fixed support 2.

[0069] The rotary connecting members 31 provided at the first end and the second end of the floating support 1 each have an axis of the rotary connecting member 31, which is the central axis of rotation.

[0070] Specifically, in the embodiment, the axes of the rotary connecting members 31 provided at the first end and the second end of the floating support 1 coincide, i.e., the central axes of rotation of the rotary connecting members 31 provided at the first end and the second end of the floating support 1 are on the same straight line, so that the floating support 1 is more stable and balanced during rotation.

[0071] In some possible implementation embodiments disclosed in the present application, as shown in Figure 2 The rotary connecting member 31 is located below the center of rotation of the roller brush body 6.

[0072] It should be noted that, due to the low position of the rotating connector 31, the torque generated when the roller brush body 6 rotates will cause the floating support 1 to have a downward tendency rather than a horizontal offset, thus achieving the effect of balancing torque, which helps to reduce the instability in the horizontal direction and improve the positional accuracy of the roller brush body 6.

[0073] Furthermore, the rotating connector 31 is located below the rotation center of the roller brush body 6, which allows the floating bracket 1 to respond more quickly to changes in the diameter of the roller brush body 6, adjust the height and angle of the roller brush by rotation, and reduce horizontal swaying and horizontal offset.

[0074] The rotation center of the roller brush body 6 can be the position of the central axis of rotation of the roller brush body 6.

[0075] Specifically, in the vertical direction, the position of the rotating connector 31 is closer to the surface to be cleaned than the rotation center of the roller brush body 6. For example, if the roller brush body 6 is placed horizontally, its rotation center is at a specific height position, while the position of the rotating connector 31 is below this height position. This allows the floating bracket 1 to move with a relatively low fulcrum when connected to and rotating with the fixed bracket 2, reducing the horizontal sway of the floating bracket 1 caused by the rotation of the roller brush body 6 and improving the stability of the cleaning equipment 7 during operation.

[0076] See some specific examples. Figure 5 As shown, the elastic drive component 32 is a torsion spring, which is sleeved on the outer periphery of the rotating connector 31. The first end of the torsion spring is connected to the floating bracket 1, and the second end of the torsion spring is connected to the fixed bracket 2.

[0077] It should be noted that when the elastic drive component 32 is a torsion spring, the torsion spring is set on the outer periphery of the rotating connector 31, making full use of the space around the rotating connector 31, making the entire floating structure more compact and reducing the space volume occupied by the floating component 3.

[0078] Furthermore, the torsion spring is disposed on the outer periphery of the rotating connector 31, and the first end of the torsion spring is connected to the floating bracket 1, and the second end of the torsion spring is connected to the fixed bracket 2, making the connection between the torsion spring, the rotating connector 31, the floating bracket 1, and the fixed bracket 2 more compact and integrated, reducing the risk of unstable installation or loosening during operation due to the dispersion of components.

[0079] The torsion spring can be coaxially arranged with the rotary connector 31, specifically, the torsion spring can be sleeved on the rotary connector 31.

[0080] The torsional spring has elastic potential energy, so that the torsional spring can continuously provide stable elastic force for the floating support 1 during the working process of the cleaning device 7. When the roller brush body 6 contacts the surface to be cleaned, if there is an uneven area on the surface to be cleaned or the diameter of the roller brush body 6 is reduced due to wear during use, the torsional spring will deform accordingly according to the actual situation, release the elastic potential energy, and prompt the floating support 1 to adjust the position in a specific direction. In this embodiment, the specific direction is the direction towards the surface to be cleaned.

[0081] Specifically, in actual application, the first end of the torsional spring is connected with the floating support 1, and the second end of the torsional spring is connected with the fixed support 2. When there is a recessed part on the surface to be cleaned or the diameter of the roller brush body 6 is reduced due to wear during use, the roller brush body 6 may have a reduced fit with the surface to be cleaned. At this time, the torsional spring will stretch, exert a downward force on the floating support 1 through the first end, so that the floating support 1 drives the roller brush body 6 to move downward, thereby ensuring that the roller brush body 6 is tightly fitted with the surface to be cleaned.

[0082] In other specific examples, the elastic driving member 32 is a tension spring, the tension spring is inclined upward away from the floating support 1 to close to the floating support 1, the first end of the tension spring is connected with the floating support 1, and the second end of the tension spring is connected with the fixed support 2; wherein the first end of the tension spring is higher than the second end of the tension spring. Thus, when the tension spring is in a stretched state, according to the principle of force decomposition, the tension of the tension spring can be decomposed into two components in the horizontal direction and the vertical direction. Among them, the component in the vertical direction has a downward pointing property. This downward component directly acts on the floating support 1, so that the floating support 1 receives a continuous downward force. This downward component prompts the floating support 1 to continuously approach the surface to be cleaned, thereby ensuring that the roller brush body 6 can always be tightly fitted with the surface to be cleaned, and achieving high cleaning efficiency.

[0083] In actual application, the tension spring is always in a stretched state, that is, the tension spring can continuously provide stable downward force for the floating support 1 during the working process of the cleaning device 7.

[0084] In addition, the elastic driving member 32 can also have the following setting modes:

[0085] The elastic drive component 32 is a compression spring. The compression spring is inclined downwards in the direction from away from the floating bracket 1 to close to the floating bracket 1. The first end of the compression spring is connected to the floating bracket 1, and the second end of the compression spring is connected to the fixed bracket 2; wherein, the first end of the compression spring is lower than the second end of the compression spring. Thus, when the compression spring is in a compressed state, according to the principle of force decomposition, the elastic force of the compression spring can be decomposed into components in different directions. Among them, a significant downward component is generated in the vertical direction. This downward component acts directly on the floating bracket 1, just like a continuous pushing force, causing the floating bracket 1 to continuously move closer to the surface to be cleaned, ensuring that the roller brush body 6 can always closely adhere to the surface to be cleaned, providing a strong guarantee for achieving efficient cleaning.

[0086] In practical applications, the compression spring is always in a compressed state, meaning that the compression spring can continuously provide a stable downward thrust to the floating support 1 during the operation of the cleaning equipment 7.

[0087] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 6 As shown, the roller brush assembly also includes a power component 4 and a follower component 5. The power component 4 is located at the first end of the floating support 1 and can be inserted into the roller brush body 6 to drive the roller brush body 6 to rotate. The follower component 5 is located at the second end of the floating support 1 and can be fixedly connected to the roller brush body 6 to drive the roller brush body 6 to rotate. It should be noted that the power component 4 and the follower component 5 are located at opposite ends of the roller brush body 6, which can better balance the torque generated by the roller brush body 6 during rotation. This helps to reduce the uneven stress borne by the floating support 1 and improve the structural stability of the entire roller brush assembly.

[0088] The power component 4 can be a motor drive component, a pneumatic motor component, a hydraulic motor component, etc. In this embodiment, the power component 4 is a motor drive component.

[0089] Specifically, the motor drive assembly can consist of a small motor and a transmission device. The motor can be a DC motor or a brushless motor, etc., with a certain power and speed, capable of outputting sufficient power to drive the roller brush body 6 to rotate.
