Description

Technical Field

[0001] This utility model relates to the field of sweeping robots, and in particular to a cleaning device, a base station, and a cleaning system. Background Technology

[0002] With the rapid development of smart home technology, cleaning robots are becoming increasingly popular due to their highly automated cleaning functions, providing users with great convenience. Currently, advanced cleaning robots are usually equipped with dedicated base stations, which provide docking locations for the robots and perform multiple maintenance functions such as mop washing, autonomous charging, and garbage collection.

[0003] However, in practice, it has been found that when cleaning base stations, wastewater and dirt generated during the mop cleaning process can easily remain and accumulate on the surface of the base station chassis. If not cleaned thoroughly and promptly, this can not only breed bacteria and produce odors, but also affect the effectiveness of subsequent cleaning.

[0004] To address this issue, existing technologies propose using scrapers on a cleaning chassis to remove residual dirt from its surface through a scraping motion. However, because cleaning chassis are typically designed with a sloping bottom to guide wastewater towards the drain, fixed or simply installed scrapers cannot maintain full and tight contact with the sloping surface throughout the entire scraping stroke. This results in the scraper only partially contacting the bottom surface, leading to uneven cleaning, leaving blind spots, and failing to completely remove residual dirt. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cleaning device, a base station and a cleaning system.

[0006] This utility model provides a cleaning device suitable for base stations in cleaning systems, comprising:

[0007] The cleaning chassis has a sloping bottom surface for guiding the flow of waste liquid;

[0008] A cleaning assembly includes a first cleaning module for cleaning the cleaning chassis. The first cleaning module includes a rotating shaft and a first cleaning structure. The rotating shaft is directly or indirectly disposed on the cleaning chassis and configured to be driven to rotate about its own axis. The first cleaning structure is disposed on the rotating shaft and is deflected relative to the rotating shaft.

[0009] The rotation of the rotating shaft drives the first cleaning structure to move, and the first cleaning structure deflects so that its working surface fits against the inclined bottom surface to scrape off the dirt on the inclined bottom surface.

[0010] In the above technical solution, the first cleaning structure is hinged to the rotating shaft, so that the first cleaning structure can deflect relative to the rotating shaft.

[0011] In any of the above technical solutions, the first cleaning structure includes:

[0012] A connecting bracket is provided with a through-hole. The connecting bracket is sleeved outside the rotating shaft portion through the through-hole and connected to the rotating shaft portion through a hinge shaft.

[0013] At least one cleaning arm is disposed on the connecting bracket and adapted to contact the inclined bottom surface.

[0014] In any of the above technical solutions, the top end of the rotating shaft is provided with a transmission structure, which is adapted to be detachably connected to the mop part of the sweeping robot, so that the rotating shaft can be driven to rotate by the mop part.

[0015] In any of the above technical solutions, the cleaning component further includes a second cleaning module fixed on the cleaning chassis. The second cleaning module is used to clean the rag part and is provided with a through groove. At least a portion of the rotating shaft part extends into the through groove and rotates with the through groove. The transmission structure is configured to be detachably connected to the rag part via the through groove.

[0016] In any of the above technical solutions, the rotating shaft is rotatably engaged with the through groove via a bearing;

[0017] The outer periphery of the rotating shaft is provided with a limiting part for axial positioning. The limiting part abuts against the two end walls of the through groove along the axial direction to restrict the axial movement of the rotating shaft.

[0018] In any of the above technical solutions, the rotating shaft portion includes:

[0019] The cover body is provided with the aforementioned transmission connection;

[0020] The rotating shaft is detachably connected to the cover. The outer peripheral wall of the rotating shaft is provided with a protruding structure. The cover and the protruding structure are located on both sides of the through groove along the axial direction, and together they constitute the limiting part that restricts the axial movement of the rotating shaft.

[0021] In any of the above technical solutions, the bottom surface of the cover is provided with a protruding snap-fit ​​structure;

[0022] The rotating shaft is constructed as a hollow structure, and the inner ring wall of the rotating shaft is provided with a mating structure, which is adapted to and snapped into the snap-fit ​​structure.

[0023] This utility model also provides a base station, including:

[0024] The base station body is equipped with a docking station for the sweeping robot to dock;

[0025] The cleaning device as described in any of the preceding claims is located at the parking position.

[0026] This utility model also provides a cleaning system, characterized in that it includes:

[0027] Robot vacuum cleaner;

[0028] As described in any of the preceding claims, the sweeping robot is adapted to dock at or drive out of the docking position of the base station.

[0029] The first cleaning structure of this invention can deflect relative to the rotating shaft. When the rotating shaft is driven to rotate and move the first cleaning structure, the first cleaning structure can adaptively adjust the contact state between its working surface and the inclined bottom surface of the cleaning chassis by means of this deflection capability. This ensures that the working surface of the first cleaning structure can closely and continuously adhere to the inclined bottom surface under various working conditions, thereby effectively scraping away residual sewage, stains or particles. Compared with traditional cleaning components with fixed angles or rigid connections, this avoids the problem of cleaning dead corners or uneven cleaning force caused by poor fit, ensures the cleanliness of the cleaning chassis, and improves the automation level of the entire cleaning system and the user maintenance experience.

[0040] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0042] The following is a reference to the appendix. Figure 1 To be continued Figure 8 This invention describes the cleaning device 10, base station, and cleaning system provided by this utility model.

[0043] like Figure 1 and Figure 2 As shown, the cleaning device 10 provided by this utility model is suitable for the base station of the cleaning system, and includes a cleaning chassis 100 and a cleaning component 200.

[0044] The cleaning chassis 100 has an inclined bottom surface 110 for guiding the flow of waste liquid. The cleaning assembly 200 includes a first cleaning module 210 for cleaning the cleaning chassis 100. The first cleaning module 210 includes a rotating shaft portion 211 and a first cleaning structure 212. The rotating shaft portion 211 is directly or indirectly disposed on the cleaning chassis 100 and is configured to be driven to rotate about its own axis. The first cleaning structure 212 is disposed on the rotating shaft portion 211 and is deflected relative to the rotating shaft portion 211.

[0045] The rotation of the rotating shaft 211 drives the first cleaning structure 212 to move, and the first cleaning structure 212 deflects so that its working surface fits against the inclined bottom surface 110 to scrape off the dirt on the inclined bottom surface 110.

[0046] The first cleaning structure 212 of this invention can deflect relative to the rotating shaft 211, so that when the rotating shaft 211 is driven to rotate and drive the first cleaning structure 212 to move, the first cleaning structure 212 can adaptively adjust the contact state between its working surface and the inclined bottom surface 110 of the cleaning chassis 100 by means of this deflection capability. This ensures that the working surface of the first cleaning structure 212 can be tightly and continuously attached to the inclined bottom surface 110 under various working conditions, thereby effectively scraping away the sewage, stains or particles remaining on it. Compared with traditional cleaning components with fixed angles or rigid connections, it avoids the problem of cleaning dead corners or uneven cleaning force caused by poor fit, ensures the cleanliness of the cleaning chassis 100, and improves the automation level of the entire cleaning system and the user maintenance experience.

[0047] In some embodiments, the first cleaning structure 212 is hinged to the rotating shaft portion 211, such that the first cleaning structure 212 can deflect relative to the rotating shaft portion 211. Exemplarily, the axis of the hinge shaft 213 is perpendicular to the axis of the rotating shaft portion 211.

[0048] By hingedly connecting the first cleaning structure 212 to the rotating shaft 211, a clear, stable, and low-resistance axis of rotation is provided for its deflection motion relative to the rotating shaft 211. This allows the first cleaning structure 212 to smoothly rotate and deflect around the hinge axis 213 under external forces, such as contact force with the inclined bottom surface 110 or centrifugal force, while rotating with the rotating shaft 211. This achieves dynamic adaptive contact between its working surface and the inclined bottom surface 110 of the cleaning chassis 100. Compared to other possible flexible or elastic deflection schemes, the hinged connection provides a more precise rotation fulcrum and more reliable mechanical load-bearing capacity, avoiding instability in contact caused by structural deformation or drift.

[0049] In some embodiments, the first cleaning structure 212 includes a connecting bracket 2121 and at least one cleaning arm 2122. The connecting bracket 2121 has a through opening 21211, and the connecting bracket 2121 is sleeved on the outside of the rotating shaft portion 211 through the through opening 21211 and connected to the rotating shaft portion 211 through a hinge shaft 213. The cleaning arm 2122 is disposed on the connecting bracket 2121 and is adapted to contact the inclined bottom surface 110.

[0050] The way the connecting bracket 2121 is fitted allows it to be stably set around the rotating shaft 211 and forms a clear deflection axis through the independent hinge shaft 213. This ensures the accuracy of the deflection movement and the structural strength. The cleaning arm 2122 installed on the connecting bracket 2121 is a component that directly performs cleaning operations. Its position and posture can be adjusted as a whole by the deflection of the bracket, thereby ensuring that multiple cleaning arms 2122 can fit the contour of the inclined bottom surface 110 synchronously and stably as a whole.

[0051] In some embodiments, the top end of the rotating shaft portion 211 is provided with a transmission structure 21111, which is adapted to be detachably connected to the mop portion of the sweeping robot, so that the rotating shaft portion 211 can be driven to rotate by the mop portion.

[0052] When the robotic vacuum cleaner carrying the mop enters the base station and performs cleaning or returning actions, the moving mop can naturally contact and couple with the transmission structure 21111, thereby directly transferring its kinetic energy to the rotating shaft 211, converting it into the rotational power required for the cleaning module to work. This design eliminates the need to separately configure a motor, reducer, and control circuit for the cleaning device 10, significantly simplifying the internal structure of the base station and reducing manufacturing costs and energy consumption. At the same time, the detachable transmission connection ensures that the driving process only occurs during the specific stage when the robot is docked at the base station, and the two automatically disengage when not in operation, avoiding unnecessary frictional loss or interference, and improving the overall service life and reliability of the system. This transmission method directly utilizes the robot's existing entry and exit actions, realizing synchronous automatic triggering of the cleaning function without user intervention or additional control logic, optimizing the user experience, and making the energy utilization and functional integration of the entire cleaning system more efficient and reasonable.

[0053] In some embodiments, the cleaning assembly 200 further includes a second cleaning module 220 fixed on the cleaning chassis 100. The second cleaning module 220 is used to clean the wiping cloth portion and is provided with a through groove 221. At least a portion of the rotating shaft portion 211 extends into the through groove 221 and rotates with the through groove 221. The transmission structure 21111 is configured to be detachably connected to the wiping cloth portion via the through groove 221.

[0054] By assembling the second cleaning module 220 for the cleaning cloth section with the rotation support structure of the first cleaning module 210 for the self-cleaning chassis 100, efficient utilization of the base station's internal space and compact functional integration are achieved. Specifically, the through groove 221 provided on the second cleaning module 220 provides a direct and reliable mounting base and rotation support for the rotation shaft 211 of the first cleaning module 210, ensuring the accuracy and stability of its rotation axis, thereby guaranteeing the smoothness of the scraping action of the first cleaning structure 212. At the same time, the through groove 221 structurally forms a channel that allows the transmission structure 21111 to interact with the moving cloth section, enabling the transmission of driving force to be completed directly at the junction of the two modules, eliminating additional transmission space and complex mechanisms. This not only simplifies the mechanical complexity of the overall device and reduces the number of parts and assembly costs, but also enables the self-cleaning process of the chassis to be driven synchronously and automatically when the cloth section is processed by the second cleaning module 220, thereby improving the continuity, efficiency, and system reliability of the entire cleaning process.

[0055] In some embodiments, the rotating shaft portion 211 is rotatably engaged with the through groove 221 via the bearing 230. The outer periphery of the rotating shaft portion 211 is provided with a limiting portion for axial positioning. The limiting portion abuts against the two end walls of the through groove 221 along the axial direction to restrict the axial movement of the rotating shaft portion 211.

[0056] The rotational engagement between the rotating shaft 211 and the through groove 221 achieved by the bearing 230 significantly reduces frictional resistance and wear during rotation. This ensures that the rotating shaft 211 maintains a smooth, stable, and low-noise rotational motion even when subjected to the driving force from the wiping cloth and the resistance of the cleaning operation. This guarantees the stability and reliability of the movement trajectory of the first cleaning structure 212 and extends the service life of the core moving parts. Simultaneously, a limiting part specifically designed for axial positioning on the outer periphery of the rotating shaft 211 abuts against the two end walls of the through groove 221 along the axial direction, effectively limiting any axial movement or displacement that may occur during operation. This prevents problems such as poor fit, abnormal noise, or abnormal wear of the cleaning structure due to axial loosening. The synergistic effect of the bearing 230 and the axial limiting structure provides the first cleaning module 210 with a high-precision motion support that is both flexible in rotation and axially stable. This fundamentally improves the mechanical stability and consistency of the cleaning device 10 under long-term, repeated use, ensuring the continuous effectiveness of the scraping operation and the overall durability of the system.

[0057] In some embodiments, the rotating shaft portion 211 includes a cover 2111 and a rotating shaft portion 2112. The cover 2111 is provided with a transmission structure 21111. The rotating shaft portion 2112 is detachably connected to the cover 2111. The outer peripheral wall of the rotating shaft portion 2112 is provided with a protrusion structure 21121. The cover 2111 and the protrusion structure 21121 are located on both sides of the through groove 221 along the axial direction, and together constitute a limiting portion that restricts the axial movement of the rotating shaft portion 211.

[0058] By disassembling the rotating shaft portion 211 into a cover 2111 with a transmission structure 21111 and a rotating shaft portion 2112 with a protruding structure 21121, and combining the two using a detachable connection method, the assembly, maintenance, and functional realization of the rotating shaft portion 211 are optimized. The split design facilitates independent processing and precise manufacturing of each component, reducing the molding difficulty and cost of the overall complex component. The protruding structures 21121 on the outer peripheral walls of the cover 2111 and the rotating shaft portion 2112 are located on both sides of the through groove 221 supporting them along the axial direction. After assembly, the two naturally form a reliable constraint on the bidirectional axial movement of the rotating shaft portion 211, together constituting the limiting part integrated into the rotating shaft portion 211 itself. At the same time, the detachable connection method allows the transmission structure 21111 or the rotating shaft portion 2112 to be replaced or maintained individually without replacing the entire rotating shaft portion 211 assembly, greatly improving the maintainability and service life of the device and reducing long-term maintenance costs.

[0059] In some embodiments, the bottom surface of the cover 2111 is provided with a protruding snap-fit ​​structure 21112, the pivot portion 2112 is constructed as a hollow structure, and the inner ring wall of the pivot portion 2112 is provided with a mating structure 21122, which is adapted to and snapped into the snap-fit ​​structure 21112.

[0060] By employing a specific method of interlocking the protruding snap-fit ​​structure 21112 with the matching mating structure 21122 on the inner ring wall of the hollow rotating shaft portion 2112, a fast, reliable axial connection without auxiliary tools or fasteners is achieved. This connection mechanism allows the cover 2111 and the rotating shaft portion 2112 to be assembled through simple axial alignment and pressing actions. The snap-fit ​​structure 21112 undergoes elastic deformation during insertion and returns to its original shape after being in place, forming an interlock with the mating structure 21122, greatly improving assembly efficiency. At the same time, the connection formed by the snap-fit ​​has sufficient tensile strength to effectively resist the axial force on the rotating shaft portion 2111 during operation, ensuring that the cover 2111 and the rotating shaft portion 2112 remain firmly connected during rotation and preventing accidental loosening. By placing the connection structure in the internal space of the rotating shaft portion 2112, the cavity of the hollow structure is fully utilized, avoiding interference from external additional connecting parts on the overall size or layout of surrounding components, making the structure of the rotating shaft portion 2111 more compact and its appearance cleaner. Furthermore, this snap-fit ​​method allows for non-destructive disassembly using specific tools or by applying separation force when maintenance or replacement is required, giving the rotating shaft 211 good maintainability and component replaceability. This significantly reduces the long-term use and maintenance costs of the product while ensuring connection reliability and structural simplicity.

[0061] The present invention also provides a base station, including a base station body and a cleaning device 10 of any of the foregoing embodiments. The base station body is provided with a docking position for a sweeping robot to dock, and the cleaning device 10 is disposed at the docking position.

[0062] This utility model also provides a cleaning system, including: a sweeping robot, and a base station of any of the foregoing embodiments, wherein the sweeping robot is adapted to dock or drive out of the docking position of the base station.
