Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a cleaning device and a cleaning equipment. BACKGROUND

[0002] With the increasing refinement of household cleaning needs, cleaning equipment has become an indispensable cleaning tool in modern families. The cleaning device of the common cleaning equipment on the market is usually fixed at both ends and connected to the equipment body through corresponding structures to realize the cleaning function. However, due to the structural characteristics of the installation method itself, there are certain connection or support components at the end of the cleaning device, which makes it difficult for the cleaning element on the cleaning device to approach the edge area when moving along the wall, skirting or furniture edge, thereby forming a larger cleaning blind area during edge cleaning, affecting the overall cleaning effect and user experience. SUMMARY

[0003] The present application provides a cleaning device and a cleaning equipment to improve the technical problem that a larger cleaning blind area is easily generated during cleaning of the wall, skirting or furniture edge by the cleaning device.

[0004] The present application provides a cleaning device, which comprises a shell, a support assembly and a cleaning element; the shell has a receiving cavity, one end of the receiving cavity in the length direction has a lateral opening; the support assembly is arranged in the receiving cavity, the support assembly is connected with the shell, and the end close to the lateral opening forms a free end; the cleaning element is wound and arranged on the outer periphery of the support assembly, the cleaning element has a first end and a second end arranged opposite in the length direction of the receiving cavity, and the first end is arranged close to the lateral opening; a first driving assembly is arranged on the shell and / or the support assembly, which is used to drive the cleaning element to rotate to perform cleaning work; wherein the lateral opening can expose the first end in the direction from the first end to the second end.

[0005] The beneficial effects of such arrangement are as follows: in the cleaning device of the present embodiment, the shell is provided with a lateral opening at one end in the length direction, and the support assembly is arranged in the shell and the end close to the opening is a free end. The cleaning element is installed on the support assembly, and the end close to the opening can be fully exposed through the lateral opening. Due to the free end design of the support assembly at the end close to the lateral opening, the end close to the edge of the cleaning element does not need to be provided with the outer end buckle and the corresponding installation space in the traditional structure. When the cleaning equipment moves along the wall, skirting or furniture edge, the exposed end (i.e. the first end) of the cleaning element can directly and fully approach these edge areas, thereby significantly reducing the cleaning blind area caused by structural limitations. This improvement effectively improves the cleaning effect of the edge area, especially in the areas such as the lower part of the wall skirting and the periphery of the furniture leg where the traditional cleaning blind area is more obvious, more thorough cleaning can be achieved, thereby improving the overall cleaning efficiency and user experience.

[0006] In an embodiment of the present application, along the length direction of the accommodation cavity, at one end of the lateral opening, the outer edge of the shell and / or the outer edge of the support assembly exceeds the outer edge of the first end.

[0007] The beneficial effect of such an arrangement is that by providing various embodiments such as the shell exceeding, the support assembly exceeding, or both exceeding, the design can be flexibly adapted to different product forms and cleaning scene requirements, providing more optimization space for product design. Compared with the cleaning blind area inevitably formed by the traditional end joint structure, even in the case where the edge of the shell or the support assembly exceeds the edge of the cleaning, the resilient deformation mechanism can make the cleaning element closer to the edge area, thereby achieving effective edge cleaning and improving the overall cleaning effect of the cleaning device.

[0008] In an embodiment of the present application, along the length direction of the accommodation cavity, at one end of the lateral opening, the outer edge of the shell and / or the outer edge of the support assembly is flush with the outer edge of the first end.

[0009] The beneficial effect of such an arrangement is that in the present embodiment, by arranging the outer edge of the shell and / or the outer edge of the support assembly to be flush with the outer edge of the first end of the cleaning element, the first end of the cleaning element is maximally close to the outermost edge of the shell in terms of structural layout. This design ensures that when the cleaning device is close to the edge area of the wall, furniture, etc., the cleaning element can produce effective adaptive deformation when subjected to slight extrusion due to its own elastic deformation characteristics. During this deformation process, the first end of the cleaning element can extend to the outside of the shell profile, preferentially achieving full contact with the edge area to be cleaned, thereby achieving stable and reliable edge cleaning effect. At the same time, by providing various embodiments such as the outer edge of the shell being flush with the outer edge of the first end, the outer edge of the support assembly being flush with the outer edge of the first end, or both being flush with the outer edge of the first end, the design can be flexibly adapted to different product forms and cleaning scene requirements, providing more optimization space for product design.

[0010] In an embodiment of the present application, when the cleaning element is in contact with the surface to be cleaned for cleaning operation, along the length direction of the accommodation cavity, at one end of the lateral opening, the outer edge of the first end exceeds the outer edge of the shell and the outer edge of the support assembly.

[0011] The beneficial effects of the arrangement are as follows: when the cleaning piece is performing a cleaning operation, the first end can be ensured to better and fully adhere to the edge region, avoiding the limitation of the outer edge of the shell or the support assembly on the outer edge of the first end of the cleaning piece. Before the cleaning piece is compressed and deformed, physical zero-distance contact with the edge region can be achieved, thereby fundamentally eliminating the edge cleaning blind area formed by the shell or the support assembly. At the same time, due to the adoption of the above arrangement, a larger effective extension allowance can be formed, so that the cleaning piece can have better deformation adaptation and adhesion ability when facing irregular edge regions, thereby further improving the cleaning effect of the edge region.

[0012] In an embodiment of the present application, in a state where the cleaning piece is separated from the surface to be cleaned, the outer edge of the shell and / or the outer edge of the support assembly exceeds the outer edge of the first end.

[0013] The beneficial effects of the arrangement are as follows: in the present embodiment, when the cleaning piece is separated from the surface to be cleaned, the outer edge of the shell or the support assembly exceeds the outer edge of the first end of the cleaning piece. This structure can effectively protect the first end of the cleaning piece in a non-cleaning operation state, thereby reducing the possibility of accidental collision or wear during transportation or idling.

[0014] In an embodiment of the present application, in a state where the cleaning piece is separated from the surface to be cleaned, the outer edge of the first end is flush with the outer edge of the shell and / or the outer edge of the support assembly.

[0015] The beneficial effects of the arrangement are as follows: when the cleaning piece is separated from the surface to be cleaned, the outer edge of the first end is flush with the outer edge of the shell and / or the support assembly. In this way, on the one hand, in a non-cleaning operation state, the flush structure can effectively protect the first end of the cleaning piece, reducing the risk of damage due to collision or friction during transportation or idling. On the other hand, this structure allows the first end of the cleaning piece to be in close contact with the outer contour of the shell during non-cleaning operation, so that after starting the cleaning operation, the cleaning piece can be more fully in contact with the edge region of the surface to be cleaned through its compression deformation, ensuring the cleaning effect of the edge region.

[0016] In an embodiment of the present application, in a state where the cleaning piece is separated from the surface to be cleaned, the outer edge of the first end exceeds the outer edge of the shell and the outer edge of the support assembly.

[0017] The beneficial effects of this design are as follows: Using the above technical solution, even before the cleaning component is compressed and deformed, the outer edge of the first end can achieve zero-distance physical contact with the edge area, thus fundamentally eliminating blind spots in edge cleaning caused by the shell or support components. Simultaneously, this design allows the cleaning component to have a larger effective extension margin during cleaning operations, i.e., after compression and deformation. This enables it to have better deformation adaptability and fit when facing irregular edge areas, thereby further improving the cleaning effect in edge areas.

[0018] In one embodiment of the present invention, the support assembly includes a first support assembly and a second support assembly. Along the length direction of the receiving cavity, one end of the first support assembly is connected to the side of the housing away from the lateral opening, and the other end of the first support assembly is connected to one end of the second support assembly. The other end of the second support assembly forms a free end. The free end is not connected to the housing and is in a suspended state.

[0019] The advantages of this design are as follows: Since one end of the first support assembly is fixedly connected to the side of the housing away from the lateral opening along the length of the receiving cavity, and the other end is connected to one end of the second support assembly, while the other end of the second support assembly forms a free end, this design allows the entire support assembly to form a cantilevered support structure with one end fixed and the other free. Compared to a design that connects the support assembly to the housing in the middle, this structure places the connection point between the support assembly and the housing on the outer side of the cleaning component away from the lateral opening, thus completely avoiding interference from the connection structure on the installation and disassembly of the cleaning component, significantly improving the convenience of replacing the cleaning component. Simultaneously, this fixing method also provides more optimization space for the overall layout of the receiving cavity, helping to reduce its dimensional footprint in the height direction and achieving a more compact structural design.

[0020] In one embodiment of the present invention, the cleaning component is fixedly connected to the second support component, the second support component is detachably connected to the first support component, and can drive the cleaning component to move into or out of the receiving cavity from the lateral opening along the length direction of the receiving cavity.

[0021] The advantages of this design are as follows: With the above structural design, the second support component and the cleaning component together form a modular unit that can be disassembled as a whole. When it is necessary to replace or clean the cleaning component, this modular unit can be removed from the first support component, thus simplifying the operation process and improving maintenance efficiency. Furthermore, since this modular unit can be moved directly into or out along the length of the receiving cavity through a lateral opening, linear and directional disassembly and assembly operations can be achieved. This design eliminates the need for complex rotation or oblique operations during the installation and removal of the cleaning component, making the movements more intuitive and convenient. At the same time, since no additional disassembly space is required around the receiving cavity (e.g., in the height direction of the machine body), it helps to improve the overall compactness of the cleaning equipment structure and facilitates the direct replacement of the cleaning component while the cleaning device remains connected to the machine body.

[0022] In one embodiment of the present invention, the first support component includes a first connector, and the second support component includes a second connector and an operating component. The second connector and the operating component are linked together, and the operating component is exposed through a lateral opening. By operating the operating component through the lateral opening, the connection or separation between the second connector and the first connector can be controlled, so as to realize the connection or separation between the second support component and the first support component.

[0023] The advantages of this design are as follows: the control element is directly exposed through the side opening, allowing the user to easily operate it to control the connection or separation between the second and first connecting parts, thus enabling quick assembly and disassembly of the second and first support components. Based on this structural design, when replacing cleaning components, the second support component can be moved out or installed entirely by operating the control element through the side opening, without disassembling other connecting structures. This significantly simplifies the operation process, shortens replacement time, and effectively improves the convenience of cleaning component assembly and disassembly. Furthermore, since all operations are concentrated at the side opening, there is no need to reserve additional operating space or openings in other parts of the housing or body, contributing to a more integrated and compact overall design and providing greater freedom for optimizing the product's appearance and internal layout.

[0024] In one embodiment of the present invention, the first connector includes at least two oppositely arranged first snap-fit ​​portions; the second connector includes at least two oppositely arranged second snap-fit ​​portions, one second snap-fit ​​portion corresponding to one first snap-fit ​​portion; the first support component and the second support component are detachably connected through the snap-fit ​​engagement of the first snap-fit ​​portion and the second snap-fit ​​portion.

[0025] The beneficial effects of this design are as follows: The snap-fit ​​structure allows for quick disengagement or engagement of the first and second snap-fit ​​parts through simple pressing, rotating, or sliding actions, facilitating easy assembly and disassembly of the first and second support components. This feature eliminates the need for any additional tools when replacing cleaning parts or disassembling the second support component, thus improving ease of use and maintenance. Furthermore, replacing traditional screws and bolts with the snap-fit ​​structure reduces the number of parts and assembly steps, lowering overall cost and structural complexity. It also avoids inconvenience caused by tool dependence or the loss of small parts, further optimizing the user experience and product maintenance convenience.

[0026] In one embodiment of the present invention, the operating member is slidably connected to the second connecting member along the length direction of the receiving cavity, and has a first sliding position and a second sliding position; in the first sliding position, the two second locking portions can approach each other to allow the second locking portions to disengage from the corresponding first locking portions; in the second sliding position, the two second locking portions can move away from each other to allow the second locking portions to engage and be fixed with the corresponding first locking portions.

[0027] The advantages of this design are as follows: With the structural design in this embodiment, when replacing the cleaning component, the user only needs to slide the operating component to the first position to drive the two second locking parts closer together, releasing them from the locking relationship with the first locking part. This process requires no tools and is simple and quick, effectively improving the disassembly efficiency between the second and first support components. Furthermore, the entire assembly and disassembly process is based on a purely mechanical linkage of sliding and locking, avoiding the stripping and wear problems common in threaded connections and eliminating the need for complex control and power supply modules required for electric drives. This simple structure and reliable operation make it more suitable for applications requiring frequent replacement of cleaning components.

[0028] In one embodiment of the present invention, the first connector includes a sleeve portion, and a through groove is provided on the circumferential sidewall of the sleeve portion, forming a first snap-fit ​​portion; the second connector includes a rod portion, and the second snap-fit ​​portion is a snap-fit ​​block disposed on the rod portion; the rod portion can drive the second snap-fit ​​portion to be inserted into the sleeve portion, thereby realizing the snap-fit ​​fixation between the second snap-fit ​​portion and the first snap-fit ​​portion.

[0029] The advantages of this design are as follows: This embodiment features a grooved sleeve on the first connector and a locking block on the rod of the second connector. The locking block and the groove engage to achieve a fixed connection. This structure allows the rod to drive the locking block along the length of the receiving cavity into the sleeve for connection, eliminating the need for rotation, tightening, or auxiliary tools. This streamlines the assembly process and is particularly suitable for scenarios requiring frequent disassembly and replacement of cleaning components. Simultaneously, the engagement of the locking block and the groove creates both circumferential and radial constraints, effectively resisting vibrations and torsional moments during cleaning operations, preventing accidental loosening of the second support component, and ensuring the stability and continuity of the cleaning process.

[0030] In one embodiment of the present invention, when the second locking part is locked and fixed to the first locking part, the operating member is in the second sliding position; when it is necessary to release the locking between the second locking part and the first locking part, the operating member can switch to the first sliding position, so that the second locking part is disengaged from the first locking part, thereby enabling the rod part to drive the second locking part to move out of the sleeve part.

[0031] The advantages of this design are as follows: When the operating component is in the second sliding position, the two second locking parts remain far apart and stably engaged with the first locking part, forming a mechanical locking connection. This prevents accidental loosening due to vibration or external force during cleaning operations, ensuring the reliability of the connection. Disassembly is simple: just switch the operating component to the first sliding position to drive the two second locking parts closer together to separate from the first locking part. This operation requires no complicated steps and is quick and easy to implement, thus enabling rapid disassembly between the first and second connecting parts and improving the maintenance efficiency of cleaning component replacement.

[0032] In one embodiment of the present invention, the outer wall of the second snap-fit ​​portion includes a guide slope, and the sleeve portion includes a sleeve opening disposed on the side facing the second support assembly. The guide slope is used to guide the second snap-fit ​​portion into the sleeve portion from the sleeve opening.

[0033] The beneficial effects of this design are as follows: In the initial stage when the second locking part contacts the sleeve opening, the bevel effectively guides and centers the assembly, automatically compensating for minor positional deviations during assembly, allowing the locking part to smoothly slide into the sleeve. This design significantly reduces the difficulty of assembly operations and improves installation efficiency and success rate. Simultaneously, the guide bevel, through its inclined structure, decomposes part of the axial force into a component force that drives the second locking part to produce radial elastic deformation during insertion. This force conversion effectively avoids rigid collisions and direct friction between the locking part and the sleeve opening edge, making the entire insertion process more effortless and smooth, significantly improving the operating feel and user experience.

[0034] In one embodiment of the present invention, the second connector further includes two rod portions, one rod portion being connected to a second locking portion; the operating member is provided with a sliding groove, and the two rod portions are slidably installed in the sliding groove; the side wall of the rod portion is provided with a straight section and an inclined section; when the sliding groove abuts against the straight section, the two second locking portions move away from each other, and the operating member is in a second sliding position; when the sliding groove abuts against the inclined section, the sliding groove presses the two rod portions to bring the two second locking portions closer to each other, and the operating member is in a first sliding position.

[0035] The beneficial effects of this design are as follows: In this embodiment, the cooperation between the sliding groove and the rod body allows for reliable switching between the open and closed states of the second locking part, thereby enabling the locking or disengagement of the second locking part from the first locking part. In the locking state, the sliding groove engages with the straight section of the rod body, keeping the two rod bodies far apart, thus ensuring that the two second locking parts are in the open position and securely locked to the first locking part. When disengagement is required, the sliding actuator brings the sliding groove into contact with the inclined section. The sliding groove wall compresses the inclined section, using the inclined effect to force the two rod bodies closer together, causing the second locking parts to move closer together, thus achieving separation from the first locking part. This structure transforms the complex locking and disengagement actions between the second and first locking parts into a single linear sliding motion of the actuator, making operation intuitive, simple, stable, and reliable.

[0036] In one embodiment of the present invention, along the sliding direction of the slide groove relative to the rod body, a chamfered surface is provided at one end of the slide groove facing the inclined section, and the chamfered surface can guide the slide groove to slide from the straight section to the inclined section.

[0037] The beneficial effects of this design are as follows: By adding a chamfered surface, the smoothness of the slide transition between the straight and inclined sections can be improved. When the operating component is used to slide the slide from its position engaging with the straight section to its position engaging with the inclined section, the chamfered surface acts as a transition structure, guiding the edge of the slide to smoothly detach from the straight section and enter the inclined section, thereby effectively reducing potential impact, jamming, or wear at the junction of the slide and the inclined section. This not only improves the operating feel and makes the sliding process smoother and less strenuous, but also reduces the impact and wear of moving parts, extending the service life of the entire mechanism.

[0038] In one embodiment of the present invention, at least one first elastic element is provided between the two rod parts, and the elastic deformation direction of the first elastic element is consistent with the relative movement direction of the two rod parts; during the process of the slide groove sliding from the inclined section to the straight section, the first elastic element releases elastic potential energy to push the two rod parts to separate from each other.

[0039] The beneficial effects of this design are as follows: By incorporating the first elastic element, when the slide groove slides from the inclined section into the straight section, the first elastic element can instantly release elastic potential energy, automatically driving the two rod parts to move away from each other, thereby causing the second locking part to quickly and reliably reset to the open state. This automatic reset mechanism not only simplifies operation, eliminating the need for manual adjustment of the second locking part, but also ensures a stable and non-misaligned locking connection with the first locking part. Furthermore, during the process of the first locking part entering the sleeve and aligning with the second locking part, the continuous elastic opening force applied by the first elastic element allows the two second locking parts to have a certain "floating" space. When encountering alignment deviations, the second locking parts can passively and slightly retract to make way, and under the guidance of the elastic force, automatically find and lock into the correct position, thereby reducing the required docking accuracy and improving the smoothness and fault tolerance of the locking process.

[0040] In one embodiment of the present invention, the second support component further includes a main body and a mounting component. The main body is used to support and fix the cleaning component. The mounting component is fixedly connected to the side of the main body facing the second snap-fit ​​portion and is provided with a guide groove. The end of the rod portion away from the second snap-fit ​​portion is slidably installed in the guide groove. The guide groove can guide the two rod portions to move away from or close to each other.

[0041] The beneficial effects of this design are as follows: In this embodiment, the guide groove provides guidance for the movement of the rod. When the slide groove slides along the rod and drives its movement, the guide groove can constrain the two rods to move closer or further apart along a preset path, effectively preventing unexpected displacements such as deflection and jamming. This design helps ensure precise alignment and reliable engagement between the second and first engaging parts, thereby improving engagement efficiency and stability.

[0042] In one embodiment of the present invention, the rod body portion facing the guide groove includes a first stop portion, a connecting portion and a second stop portion connected in sequence. The connecting portion is slidably inserted into the guide groove. Along the length direction of the rod body portion, the first stop portion and the second stop portion respectively stop at both ends of the guide groove.

[0043] The beneficial effects of this design are as follows: By setting the first stop and the second stop, not only can the installation positioning be formed in the extension direction of the rod to avoid the probability of the rod coming out of the guide groove during operation, but also, through the contact between the first stop and the second stop and the two end faces of the guide groove, the probability of the rod deviating during operation can be further reduced, thereby further improving the guiding accuracy of the guide groove for the rod.

[0044] In one embodiment of the present invention, a sliding cavity is provided on the side of the main body away from the mounting member. The operating member includes a sliding part, a limiting part and an extension part. The sliding part is slidably installed in the sliding cavity. One end of the extension part extends into the sliding cavity and is fixedly connected to the sliding part. The other end extends toward the second snap-fit ​​part and is connected to the limiting part. A groove is provided in the limiting part.

[0045] The beneficial effects of this design are as follows: In this embodiment, the cooperation between the sliding part and the sliding cavity provides precise guidance for the operation of the control component, ensuring its smooth operation. Furthermore, by configuring the control component as a sliding part, a limiting part, and an extension part, the extension part connects the sliding part near the opening and the limiting part extending to the second engaging part, achieving linkage between the sliding groove on the limiting part and the sliding part. This optimizes the force transmission path and improves the responsiveness of the linkage between the sliding groove and the sliding part.

[0046] In one embodiment of the present invention, the inner wall of the sliding cavity and / or the outer wall of the sliding part are provided with a protruding structure, and the inner wall of the sliding cavity slides against the outer wall of the sliding part through the protruding structure.

[0047] The beneficial effects of this design are as follows: By incorporating the raised structure, the frictional conditions between the sliding part and the sliding cavity can be improved, reducing the frictional resistance generated during the sliding process. This makes the pushing and pulling operation of the control component more effortless and smoother. Simultaneously, the raised structure reduces the reliance on large-area machining precision and concentrates wear on the raised structure itself, effectively preventing gaps and wobble caused by uneven wear. This, in turn, helps maintain the stability of long-term sliding operation between the sliding part and the sliding cavity.

[0048] In one embodiment of the present invention, a second elastic member is provided between the mounting member and the limiting part, and the elastic deformation direction of the second elastic member is consistent with the sliding direction of the slide groove; during the process of the slide groove sliding from the straight section to the inclined section, the second elastic member stores elastic potential energy, and during the process of the slide groove sliding from the inclined section to the straight section, the second elastic member releases elastic potential energy to drive the slide groove to slide.

[0049] The beneficial effects of this design are as follows: By incorporating a second elastic element, on the one hand, when the external force on one side of the sliding part is removed, the elastic force generated by the second elastic element drives the slide groove to automatically slide from the inclined section to the straight section, thereby achieving automatic reset of the operating component and simplifying the operation process. On the other hand, when the slide groove slides from the straight section to the inclined section, the second elastic element is compressed and generates a counterforce. This force ensures that the slide groove is always tightly resisted along the sliding direction, thus suppressing lateral swaying and offset of the operating component during movement and improving the smoothness and stability of the operating component's operation.

[0050] In one embodiment of the present invention, the second elastic element is a compression spring, which is sleeved on the outer periphery of the extension. One end of the second elastic element abuts against the limiting part or the extension, and the other end abuts against the main body.

[0051] The advantages of this design are twofold: First, using a compression spring as the second elastic element allows for the effective storage and release of elastic potential energy, providing a continuous and stable rebound force for the control components. Second, as a standard component, the compression spring offers a complete range of specifications, low procurement costs, and a stable supply, which not only helps control product costs but also facilitates future maintenance and replacement.

[0052] In one embodiment of the present invention, the sliding cavity has a cavity opening on the side facing the lateral opening, and the operating member also includes a pull ring, which is disposed on the side of the sliding part facing the cavity opening; pulling the pull ring can drive the sliding part to slide along the sliding cavity, thereby driving the slide groove to slide from the straight section to the inclined section.

[0053] The advantages of this design are as follows: By incorporating a pull ring on the sliding part, the user can pull the ring to drive the slide groove from its position engaging with the straight section to its position engaging with the inclined section, thus quickly releasing the engagement between the second and first locking parts and improving the disassembly efficiency. Furthermore, the pull ring's ergonomic design facilitates finger application, allowing users to easily pull the control component without tools, enhancing operational convenience and the overall user experience.

[0054] In one embodiment of the present invention, a pull ring is rotatably mounted on a sliding part and has a first rotational position and a second rotational position. In the first rotational position, the pull ring unfolds toward the side close to the cavity opening and can be pulled to drive the sliding part to slide. In the second rotational position, the pull ring is folded toward the side away from the cavity opening to fit against the sliding part.

[0055] The beneficial effects of this design are as follows: In this embodiment, by rotatably mounting the pull ring onto the sliding part and setting two rotation positions, when the operating component needs to be operated, the pull ring can be switched to the first rotation position, unfolding it towards the cavity opening to provide the user with a clear point of force application, ensuring convenient and reliable operation. When the operating component is not in operation, the pull ring can be switched to the second rotation position, folding it and fitting it against the surface of the sliding part. This design helps reduce the space occupied by the pull ring when not in use, and effectively avoids problems such as snagging and impact that may be caused by the pull ring protruding during storage, transportation, or operation. This reduces cleaning failures caused by accidental pulling of the pull ring and improves the reliability of the cleaning device.

[0056] In one embodiment of the present invention, a third elastic element is provided between the pull ring and the sliding part. When the pull ring is driven by an external force to rotate from the first rotation position to the second rotation position, the third elastic element undergoes elastic deformation to store elastic potential energy. When the external force is removed, the third elastic element releases the elastic potential energy to drive the pull ring to return from the second rotation position to the first rotation position.

[0057] The beneficial effects of this design are as follows: By incorporating a third elastic element, when the external force applied to the pull ring is removed, the third elastic element immediately releases its elastic potential energy, driving the pull ring to automatically return to its unfolded first rotational position. This achieves automatic reset of the pull ring, reducing the need for manual reset procedures. Simultaneously, when the pull ring is in a folded and closed state, the clamping force applied by the third elastic element effectively suppresses loosening or shaking of the pull ring caused by vibration during the cleaning process, thus avoiding noise caused by pull ring rotation displacement or abnormal sounds.

[0058] In one embodiment of the present invention, the third elastic element is a torsion spring, the pull ring is rotatably connected to the sliding part through a rotating shaft, the sliding part is provided with a protrusion, the third elastic element is sleeved on the outer periphery of the rotating shaft, and the two connecting ends of the third elastic element abut against the protrusion and the pull ring respectively.

[0059] The advantages of this design are as follows: In this embodiment, a torsion spring is used as the third elastic element, with its two connecting ends abutting against the protrusion and the pull ring, respectively. This design eliminates the need for a complex fixing structure and requires minimal installation space, thus simplifying the assembly process of the third elastic element and facilitating a compact design at the pull ring location. Furthermore, the torsion spring primarily withstands torsional deformation during operation; its material exhibits high fatigue strength and excellent wear resistance, enabling it to withstand frequent rotational reset conditions and maintain a stable elastic restoring force over a long period.

[0060] In one embodiment of the present invention, a cleaning component is wound around the outer periphery of a support assembly, and the cleaning component is a roller-type rag or a track-type rag; the cleaning device further includes a first driving assembly, which is disposed on the housing and / or the support assembly, for driving the cleaning component to rotate in order to perform cleaning operations.

[0061] The beneficial effects of this design are as follows: This embodiment designs the cleaning component as a roller-type or track-type cloth wound around the outer periphery of the support assembly, and configures a corresponding first drive assembly to drive the cleaning component to rotate. This satisfies the structural and functional requirements of conventional roller or track-type cloths. The rotational motion of the cleaning component achieves continuous and efficient wiping, which helps to expand the coverage area of ​​a single cleaning cycle and improve cleaning efficiency and effectiveness.

[0062] In one embodiment of the present invention, the first support component is provided with a cavity, the first drive component is accommodated in the cavity and fixedly connected to the first support component; the first drive component has a rotating output end extending to the outside of the cavity, and a first connector is fixedly connected to the rotating output end.

[0063] The beneficial effects of this design are as follows: In this embodiment, a cavity is provided inside the first support component to accommodate the first drive component, achieving structural and functional integration. This design allows the first support component to not only provide structural support but also to install and support the first drive component, thus making full use of its internal space and avoiding the first drive component occupying additional external installation space. This not only improves the space utilization efficiency of the internal cavity but also provides effective support for the compact and miniaturized design of the overall cleaning device structure. Furthermore, since the support component adopts a cantilever structure at one end, its lateral opening end is prone to tilting upwards during cleaning operations due to uneven force, affecting the cleaning effect. In this embodiment, by placing the first drive component with a certain mass near the free end of the cantilever, it is equivalent to adding a counterweight to that side, effectively balancing the torque generated by the cantilever structure and reducing the tendency for the lateral opening end to tilt upwards. This counterweight design helps ensure that the cleaning component maintains stable and sufficient contact pressure with the surface to be cleaned during operation, thereby improving the cleaning effect and operational stability.

[0064] In one embodiment of the present invention, the first support component includes a first cylinder and a second cylinder. Along the length direction of the receiving cavity, one end of the second cylinder is fixedly connected to the side of the shell away from the lateral opening, and the other end is fixedly connected to the first cylinder through a snap-fit ​​structure, forming a cavity. The first drive component is fixedly installed on the first cylinder.

[0065] The advantages of this design are as follows: By using a snap-fit ​​structure to connect and fix the first and second cylinders, compared to the traditional bolt connection method, this design has the advantages of simple assembly, stable connection, and no need for additional fasteners. This not only improves the assembly efficiency between the first and second cylinders, but also facilitates subsequent disassembly and maintenance, thus providing convenience for the maintenance of the first drive component inside the cavity.

[0066] In one embodiment of the present invention, the snap-fit ​​structure includes a snap-fit ​​groove and a snap-fit ​​protrusion adapted to the snap-fit ​​groove; one of the snap-fit ​​groove and the snap-fit ​​protrusion is disposed in the first cylinder and the other is disposed in the second cylinder, and the first cylinder and the second cylinder are fixedly connected by snap-fit ​​between the snap-fit ​​groove and the snap-fit ​​protrusion.

[0067] The advantages of this design are as follows: The snap-fit ​​groove and snap-fit ​​protrusion structure used in this embodiment is simple and easy to directly process and form on the first and second cylinders, which helps to reduce mold complexity and manufacturing costs. At the same time, this snap-fit ​​connection method is stable and reliable, and can effectively transfer working loads, ensuring the integrity of the structure while balancing assembly efficiency and connection performance.

[0068] In one embodiment of the present invention, the snap-fit ​​structure further includes a plug-in portion and a plug-in groove adapted to the plug-in portion. One of the plug-in portion and the plug-in groove is disposed on the first cylindrical member and the other is disposed on the second cylindrical member. The plug-in portion can be inserted into the plug-in groove along the length direction of the first cylindrical member to guide and position when the snap-fit ​​groove and the snap-fit ​​protrusion snap together.

[0069] The beneficial effects of this design are as follows: This embodiment further optimizes the assembly process of the first and second cylinders by adding mutually compatible plug-in parts and plug-in slots to the snap-fit ​​structure. Before the snap-fit ​​protrusion mates with the snap-fit ​​slot, the plug-in part can be pre-inserted into the plug-in slot along the length of the first cylinder, forming axial guidance and radial limiting, effectively guiding the quick alignment of the snap-fit ​​slot and the snap-fit ​​protrusion, and avoiding misalignment or skewness during the snap-fit ​​process. Therefore, this structural component can improve the snap-fit ​​assembly accuracy and snap-fit ​​connection efficiency between the first and second cylinders. At the same time, the plug-in mating can enhance the overall connection rigidity and torsional stability between the first and second cylinders, thereby ensuring that the snap-fit ​​structure maintains reliable connection performance even under complex working conditions.

[0070] In one embodiment of the present invention, a bottom wall is provided at the end of the first cylindrical component away from the second cylindrical component, and the bottom wall is provided with a mounting hole; the first driving component is fixed to the bottom wall, and the rotation output end passes through the mounting hole; the side of the first driving component facing the bottom wall has a mounting end face, and a sealing element is provided between the mounting end face and the bottom wall, the sealing element being used to achieve a seal between the mounting end face and the bottom wall.

[0071] The beneficial effects of this design are as follows: Since the first and second cylinders are installed near the cleaning components, dirt can easily penetrate the cavity formed by the first and second cylinders during cleaning, leading to contamination of the first drive assembly. In this embodiment, a seal is provided at the mounting hole location, effectively achieving a reliable seal at the mounting site of the first drive assembly. This sealing structure prevents external dirt from entering the cavity formed by the first and second cylinders through the gap in the mounting hole, thereby reducing the risk of contamination to the first drive assembly and ensuring its long-term stable operation during cleaning.

[0072] In one embodiment of the present invention, the first support component further includes a mounting base, which is detachably connected to the end of the second cylinder away from the first cylinder and fixedly connected to the side of the housing away from the lateral opening.

[0073] The advantages of this design are as follows: By designing the mounting base and the second cylinder as separate structures with a detachable connection, this embodiment effectively optimizes the connection performance between the first support component and the shell. Since the first support component uses a cantilever mounting structure, its connection point with the shell needs to withstand a large bending moment, requiring high material strength. The separate design allows the mounting base to be made of high-strength materials to fully meet structural load-bearing requirements, while the second cylinder can use lower-cost or lighter ordinary materials. This combination ensures connection reliability while balancing manufacturing costs and lightweight requirements.

[0074] In one embodiment of the present invention, the housing further includes a side wall and an end wall. The end wall is disposed at the end of the receiving cavity away from the lateral opening and together with the side wall forms the receiving cavity. The mounting base is fixedly connected to the end wall, and the thickness of the end wall is greater than the thickness of the side wall.

[0075] The beneficial effects of this design are as follows: By thickening the end walls, localized reinforcement of the critical stress areas of the shell is achieved. This design not only improves the support stiffness and strength of the end wall areas, enabling them to reliably withstand the bending moment and vibration loads transmitted by the first support component and meet the load-bearing requirements, but also avoids increasing the overall shell wall thickness to improve local strength. This allows for a more rational distribution of materials and a lightweight design while ensuring the reliability of the shell structure.

[0076] In one embodiment of the present invention, a first support structure is provided at the end of the first support component away from the second support component, and the first support structure is sleeved on the outer periphery of the first support component; the cleaning component is rotatably supported on the outer periphery of the first support component through the first support structure.

[0077] The beneficial effects of this design are as follows: In this embodiment, by setting a first support structure, the cleaning component is rotatably supported on the outer periphery of the first support assembly via the first support structure. This design avoids direct contact and friction between the inner wall of the cleaning component and the outer peripheral surface of the first support assembly, thereby mitigating the impact of uneven friction on synchronous rotation performance and reducing the risk of twisting or deformation of the cleaning component, thus ensuring the stability and reliability of the cleaning effect. Furthermore, when replacing the cleaning component, the first support structure effectively reduces the frictional resistance when the first support assembly is inserted into the cleaning component, allowing it to enter the cleaning component more smoothly, thereby improving the efficiency of cleaning component replacement.

[0078] In one embodiment of the present invention, the first support structure includes a rotating member and a support sleeve. The support sleeve is fixedly sleeved on the outer periphery of the rotating member, and the rotating member is rotatably mounted on the outer periphery of the first support assembly. The support sleeve abuts against the inner wall of the cleaning member, and the rotation of the cleaning member causes the support sleeve to rotate relative to the first support assembly.

[0079] The beneficial effects of this design are as follows: This embodiment achieves functional separation of friction transmission and rotational support by employing a split design for the rotating component and the support sleeve. The support sleeve is specifically responsible for friction transmission with the inner wall of the cleaning component, and can be made of high-friction coefficient materials such as rubber or polyurethane to significantly enhance transmission friction and effectively prevent slippage. The rotating component focuses on providing stable rotational support, and can be made of low-friction coefficient wear-resistant materials such as POM or nylon, or directly use a rotary bearing to ensure smooth and durable rotation. Therefore, the above-mentioned split structure allows for targeted optimization of the performance of each component, avoiding the increased design difficulty of a single component having to accommodate multiple performance aspects, thus resulting in better design adaptability.

[0080] In one embodiment of the present invention, the outer peripheral surface of the support sleeve includes a first support surface and a first guide surface. The first support surface is used to abut against the inner wall of the cleaning component, and the first guide surface is connected to the side of the first support surface near the second support component, and is used to guide the cleaning component to be sleeved on the first support surface.

[0081] The beneficial effects of this design are as follows: By providing a first guiding surface, the cleaning component can automatically center and guide the assembly during the insertion process. This design effectively reduces insertion resistance during assembly, preventing scratches or deformation of the inner wall of the cleaning component due to forced insertion, thereby improving the installation efficiency of the cleaning component and the first support assembly and protecting the structural integrity of the cleaning component.

[0082] In one embodiment of the present invention, a plurality of first protrusions are provided on the outer periphery of the support sleeve. The plurality of first protrusions are spaced apart along the circumferential direction of the support sleeve. The outer side wall of the first protrusion includes a first inclined wall surface. The first inclined wall surfaces of the plurality of first protrusions together form a first guide surface.

[0083] The beneficial effects of this design are as follows: By providing the first protrusion, the first guide surface can form multiple local surfaces spaced apart along the circumferential direction. This reduces the frictional resistance during the insertion of the cleaning component into the first guide surface, further improving the smoothness of the insertion.

[0084] In one embodiment of the present invention, a second support structure is fixedly connected to the rotating output end, and the outer peripheral surface of the second support structure at least partially abuts against the inner wall of the cleaning component.

[0085] The beneficial effects of this design are as follows: By fixing a second support structure to the rotary output end, and ensuring that at least part of the outer circumferential surface of the second support structure abuts against the inner wall of the cleaning component, a support for the cleaning component is formed at the rotary output end. Adding a support point at the corresponding position at the rotary output end effectively constrains the radial runout of the cleaning component at that location, forming a distributed support system across regions. This, in turn, improves the overall stability of the cleaning component during high-speed rotation, reducing vibration and sway. Simultaneously, the contact between the second support structure and the inner wall of the cleaning component increases the transmission friction area and force, effectively preventing relative slippage between the cleaning component and the rotary output end, ensuring precise speed synchronization, and avoiding uneven cleaning or efficiency reduction caused by slippage.

[0086] In one embodiment of the present invention, the second support structure is fixedly connected to the rotating output end. The outer peripheral surface of the second support structure includes a second support surface and a second guide surface. The second support surface is used to abut against the inner wall of the cleaning component. The second guide surface is connected to the side of the second support surface facing the first support component and is used to guide the cleaning component to be sleeved on the second support surface.

[0087] The beneficial effects of this design are as follows: By providing a second guide surface, the cleaning component can automatically center and guide the assembly during insertion into the second support structure. This design effectively reduces insertion resistance during assembly, preventing scratches or deformation of the cleaning component's inner wall due to forced insertion. This improves the smoothness of insertion between the cleaning component and the second support structure, thereby further enhancing the efficiency of cleaning component installation and replacement.

[0088] In one embodiment of the present invention, a plurality of second protrusions are provided around the outer periphery of the second support structure, and the outer side wall of the second protrusions includes a second inclined wall surface, and the second inclined wall surfaces of the plurality of second protrusions together form a second guide surface.

[0089] The beneficial effects of this design are as follows: By providing the second protrusion, the second guide surface can form multiple local surface bodies spaced apart along the circumferential direction. This reduces the frictional resistance during the insertion of the cleaning component into the second guide surface, further improving the smoothness of the insertion.

[0090] In one embodiment of the present invention, the outer wall of the second protrusion further includes a straight wall surface, which is connected to the side of the second inclined wall surface away from the first support component, and the straight wall surfaces of the plurality of second protrusions together form a second support surface.

[0091] The beneficial effects of this design are: by providing a straight wall surface on the second protrusion, the second support surface can form multiple local surface bodies spaced apart along the circumferential direction. This reduces the frictional resistance during the insertion of the cleaning component into the second support surface, further improving the smoothness of insertion.

[0092] In one embodiment of the present invention, the first support component includes a first connector connected to a rotating output end, and a second support structure fixedly connected to the first connector. At least one positioning groove is provided on the outer periphery of the first connector and / or the second support structure, and at least one positioning block is provided on the inner wall of the cleaning component. The positioning block is correspondingly engaged in the positioning groove so as to achieve positioning of the first connector and the cleaning component in the circumferential direction.

[0093] The beneficial effects of this design are as follows: By setting up positioning grooves and positioning blocks, and ensuring that the positioning blocks and positioning grooves interlock, a direct torque transmission path is formed between the first connecting member and the cleaning member. Since the first connecting member is connected to the rotating output end of the first drive assembly, this design can effectively transmit the output torque to the cleaning member, thereby reducing the probability of the cleaning member slipping relative to the rotating output end in the circumferential direction, and further improving the stability and reliability of the cleaning member during operation.

[0094] In one embodiment of the present invention, the cleaning component is a tracked rag or a roller rag, and the receiving cavity is provided with a bottom opening on the side facing the cleaning surface. The bottom opening is used to expose the cleaning component for cleaning operations. The housing is provided with an abutment on the side near the lateral opening. Along the height direction of the cleaning device, the abutment is at least partially located above the bottom opening to apply a force to the cleaning component toward the surface to be cleaned.

[0095] The beneficial effects of this design are as follows: By placing an abutment above the bottom opening on the side of the housing near the lateral opening, this abutment can apply a force to the cleaning component toward the surface to be cleaned. This design allows the cleaning component to obtain effective auxiliary downward pressure on the free end side of the support assembly, compensating for the pressure loss caused by insufficient support stiffness on the free end side of the support assembly. This improves the problems of uneven cleaning pressure distribution and poor cleaning effect at the free end, ensuring the overall cleaning performance of the cleaning equipment.

[0096] In one embodiment of the present invention, the cleaning device further includes a squeegee structure, which extends at least partially into the receiving cavity and contacts the cleaning component to squeegee off wastewater on the cleaning component, and the abutment member is capable of applying a force to the cleaning component toward the squeegee structure.

[0097] The beneficial effects of this design are as follows: In this embodiment, the abutment component applies a force towards the squeegee structure to the cleaning component, ensuring that the cleaning component maintains stable and close contact with the squeegee structure during operation. This design not only ensures the effective removal of wastewater by the squeegee structure but also suppresses bending deformation of the cleaning component away from the squeegee structure due to force on the side near the lateral opening. Therefore, it guarantees the stability of the cleaning component during rotation and maintains a stable effective cleaning area between the cleaning component and the surface to be cleaned, thereby improving the overall reliability and consistency of the cleaning operation.

[0098] In one embodiment of the present invention, the cleaning component is a roller-type wiping cloth, and the abutment is an arc-shaped surface structure adapted to the cleaning component; along the length direction of the receiving cavity, the projected outline of the abutment extends at least partially above the bottom opening and at least partially to the opposite side of the squeegee structure.

[0099] The beneficial effects of this design are as follows: By designing the abutment component as an arc-shaped structure adapted to the roller-type cleaning cloth, and ensuring its projected outline simultaneously covers the area above the bottom opening and the opposite side of the squeegee structure, this design effectively compensates for the pressure loss of the support assembly at the free end by applying pressure towards the surface to be cleaned, ensuring uniformity of the cleaning effect. Furthermore, it also applies a force towards the squeegee structure, ensuring a tight fit between the squeegee structure and the surface of the cleaning component, improving wastewater removal efficiency. In addition, the arc-shaped structure provides a uniform and stable abutment force in the circumferential direction of the cleaning component, helping to suppress abnormal deformation and vibration during rotation, thus enhancing the smoothness and reliability of the cleaning component's rotation.

[0100] In one embodiment of the present invention, the cleaning device further includes a squeegee structure that extends at least partially into the receiving cavity and contacts the cleaning component to squeegee off wastewater on the cleaning component; the housing is provided with an abutment on the side near the lateral opening, the abutment being able to apply a force to the cleaning component toward the side of the squeegee structure.

[0101] The beneficial effects of this design are as follows: By incorporating the abutment element and applying a force towards the wiping structure to the cleaning element, it effectively ensures that the cleaning element maintains a tight and stable contact with the wiping structure in the wiping area. This improves the efficiency and thoroughness of wastewater removal, and alleviates problems such as incomplete wiping and wastewater residue caused by loose fit of the cleaning element.

[0102] The present invention also provides a cleaning device, which is a self-moving cleaning device, including a body and at least one cleaning device as described in any of the above embodiments, wherein the cleaning device is installed on the body.

[0103] The present invention also provides a cleaning device, which includes a body and at least one cleaning device as described in any of the above embodiments, the cleaning device being installed on the body; along the width direction of the body, the outer edge of the housing is flush with or extends beyond the outer edge of the body; the width direction of the body is perpendicular to the travel direction of the body.

[0104] The beneficial effects of this design are as follows: Because the cleaning device described in the previous embodiment is installed on the machine body, when the cleaning device moves along the walls, baseboards, or furniture edges, the exposed end (i.e., the first end) of the cleaning component can directly and fully approach these edge areas, thereby significantly reducing cleaning blind spots caused by structural limitations. Therefore, the cleaning effect on edge areas can be improved, especially in areas where traditional cleaning blind spots are more obvious, such as the lower part of wall baseboards and the perimeter of furniture legs, achieving a more thorough cleaning and thus improving overall cleaning efficiency and user experience.

[0105] In one embodiment of the present invention, the cleaning device further includes an outward swing component. The cleaning device is connected to the machine body through the outward swing component. The outward swing component is retractably installed on the machine body and can drive the cleaning device to operate between an inward position and an outward swing position. In the outward swing position, the cleaning device can extend to the outside of the machine body along the width direction or the edge of the cleaning device can be flush with the edge of the machine body.

[0106] The beneficial effects of this design are as follows: the cleaning device and the outward swing component work together. The outward swing component drives the cleaning device to swing outward, allowing the cleaning component to actively conform to the edges of the area to be cleaned. When the cleaning device travels or turns along walls, furniture edges, or baseboards, this structure allows the exposed end (i.e., the first end) of the cleaning component to directly and fully approach the wall, baseboard, or furniture edge, significantly reducing cleaning blind spots caused by structural limitations. This design significantly expands the effective cleaning range of the device, improving the cleaning effect in edge and corner areas, especially in areas with obvious traditional cleaning blind spots such as the lower part of walls and baseboards, and around furniture legs, achieving a more thorough cleaning, thereby improving overall cleaning efficiency and user experience.

Detailed Implementation

[0165] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0166] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0167] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0168] In existing cleaning equipment 1000, the cleaning device 100 (such as a roller-type cloth, a conveyor belt-type cloth, or a roller brush) typically adopts a fixed-end installation structure to achieve stable assembly on the body 200 of the cleaning equipment 1000. Taking a common roller-type cleaning device as an example, its roller-type cloth (i.e., cleaning component) mostly adopts a horizontal pull-out installation method, and the end of the roller-type cloth near the edge area is connected and fixed to the housing 10 of the cleaning device 100 by an external end clip. Due to the limitations of this structural design, the end of the roller-type cloth near the cleaning edge will have reserved installation space for the external end clip, which may create a cleaning blind spot of about 3-5mm near the edges of walls, baseboards, or furniture legs. These areas are often where dust, hair, and other debris tend to accumulate. For example, in the area below the baseboard, because the cleaning component 30 cannot effectively get close, the accumulated dust may not be completely removed, and the user still needs to perform a second manual wiping. In narrow areas such as sofa legs and cabinet bottoms, the cleaning component 30 cannot effectively reach the edges, potentially leading to hair entanglement and dirt residue. This issue is more pronounced in small apartments or densely furnished spaces, impacting the actual effectiveness of the cleaning device 1000. Therefore, the existing cleaning device 100 still has room for improvement in its edge-cleaning capabilities, necessitating an improvement solution that alleviates or overcomes these structural limitations.

[0169] Based on the shortcomings of the existing technology mentioned above, please refer to Figures 1 to 54This invention provides a cleaning device 100 and a corresponding cleaning equipment 1000. The cleaning device 100 includes a housing 10 and a support assembly 20. The housing 10 has a lateral opening 111 at one end along its length. The support assembly 20 is disposed within the housing 10, with its end near the lateral opening 111 being a free end. A cleaning component 30 is mounted on the support assembly 20, with its end near the lateral opening 111 fully exposed through the opening. This design eliminates the need for external end clips and reserved installation space at the edge end of the cleaning component 30, as is common in traditional structures. When the cleaning equipment 1000 moves along walls, baseboards, or furniture edges, the exposed end of the cleaning component 30 can be as close as possible to these edge areas, significantly reducing cleaning blind spots caused by structural limitations. This improvement effectively enhances the cleaning of edge areas, especially in areas that are traditionally difficult to clean, such as the lower part of wall baseboards and around furniture legs. It enables a more thorough cleaning, thereby improving overall cleaning efficiency and user experience.

[0170] The cleaning device 1000 provided in the embodiments of the present invention can be a self-moving cleaning robot or a handheld floor scrubber. The self-moving cleaning robot can be a mopping robot or a sweeping and mopping robot, etc. In the following embodiments, some components of the cleaning device 1000 are described as a self-moving cleaning robot, but those skilled in the art will understand that other robots including the cleaning device 100 of the present invention can also have the beneficial effects brought by the cleaning device 100 of the present invention.

[0171] Please see Figure 1 and Figure 53 The cleaning device 1000 has a body 200, the interior of which can accommodate various components of the cleaning device 1000. The body 200 can have any shape, such as cylindrical, elliptical, or D-shaped. The cleaning device 1000 also includes a walking system conventionally provided on existing cleaning devices 1000, used to drive the body 200 to move independently, enabling it to move on the surface to be cleaned. The walking system includes at least a driver and drive wheels, which rotate under the action of the driver. There are generally two drive wheels, symmetrically arranged at the bottom of the body 200. The specific structure of the walking system and the connection structure between the walking system and the body 200 can be found in the relevant structural descriptions of existing cleaning devices 1000, and will not be repeated here.

[0172] The cleaning equipment 1000 includes at least one cleaning device 100. The cleaning device 100 is detachably connected to the body 200, and the detachable connection method can be a snap-fit ​​detachable connection, a bolt detachable connection, etc. The cleaning device 100 can be configured for dry mopping or wet mopping. Optionally, in this embodiment, the cleaning device 100 is configured for wet mopping.

[0173] Alternatively, in one embodiment, please refer to Figure 1 and Figure 53 The cleaning device 1000 may further include a side brush 210 and a roller brush 220, both located at the bottom of the body 200. Along the traveling direction of the body 200, both the side brush 210 and the roller brush 220 are positioned in front of the cleaning device 100. The side brush 210 may be positioned at the edge of the body 200 and can rotate via a rotating mechanism, such as a combination of a motor and a reducer. When the side brush 210 rotates, it gathers debris from the edge of the body 200 towards the inside of the body 200, thereby increasing the cleaning range of the cleaning device 1000. The side brush 210 can be a rubber strip or a bristle brush, as long as it can clean the ground; there are no restrictions here. The roller brush 220 is rotatably mounted in a roller brush cavity at the bottom of the body 200. During its rolling motion, the roller brush 220 can sweep away debris on the ground. The number of roller brushes 220 can be set according to specific requirements; this embodiment does not limit the number. Along the traveling direction of the machine body 200, the side brush 210 and the roller brush 220 are positioned in front of the cleaning device 100. This facilitates the cleaning operation of the cleaning device 1000, which involves dry sweeping followed by wet mopping, and also facilitates the layout of the internal space of the machine body 200.

[0174] Of course, those skilled in the art will understand that in some other embodiments, the cleaning device 1000 may only be equipped with a cleaning device 100 for cleaning operations, without the roller brush 220 or the side brush 210.

[0175] In addition, the cleaning equipment 1000 may also include a sensing system and a control system. The sensing system and control system are electrically connected. The sensing system includes an LDS (Light Detection and Ranging) located on top of the body 200, a buffer and vision sensor located at the front of the body 200, and an edge sensor located on the front side wall of the body 200. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the body 200 and obstacles. The control system controls the cleaning equipment 1000 to perform corresponding actions based on this distance. For example, it controls the cleaning equipment 1000 to perform obstacle avoidance, edge cleaning, and return to the base station.

[0176] The cleaning device 100 can be implemented in various ways; optionally, in this embodiment, please refer to... Figures 2 to 4 The cleaning device 100 includes: a housing 10, a support assembly 20, and a cleaning component 30.

[0177] The housing 10 is mounted below the body 200, and the mounting method can be a snap-fit ​​connection, a bolt connection, etc. The housing 10 has a receiving cavity 11, and the length direction of the receiving cavity 11 (e.g., ...) Figure 4 One end of the cavity 11 (shown on the X-axis) has a lateral opening 111. The length direction of the cavity 11 is consistent with the width direction of the body 200, and the width direction of the body 200 is perpendicular to the travel direction of the cleaning equipment 1000.

[0178] Please see Figures 2 to 4 The support assembly 20 is disposed within the receiving cavity 11 and is connected to the housing 10. The support assembly 20 has a free end near the lateral opening 111. The cleaning component 30 is fixedly installed on the support assembly 20. The specific structure of the support assembly 20 is not limited and needs to be determined based on the structural form of the cleaning component 30. For example, when the cleaning component 30 is a roller-type cloth, the support assembly 20 is a roller support structure adaptable to the roller-type cloth. When the cleaning component 30 is a tracked cloth, the support assembly 20 is a tracked support structure adaptable to the tracked cloth.

[0179] In this embodiment, the connection position between the support component 20 and the housing 10 is not limited to a specific position. In the length direction of the receiving cavity 11, the support component 20 can be fixedly connected to the housing 10 at the end away from the lateral opening 111, or it can be fixedly connected to the housing 10 at approximately the middle position in the length direction of the receiving cavity 11, as long as it is ensured that the support component 20 can form a free end at the end near the lateral opening 111.

[0180] It should be noted that in this embodiment, the support component 20 forms a free end at the end near the side opening 111. Specifically, the support component 20 does not establish any connection or fixed relationship with the housing 10 at the end near the side opening 111, and remains in a completely independent suspended state. The entire support component 20 is only connected and supported to the housing 10 through the end away from the side opening 111 or the middle part of the support component 20.

[0181] Please see Figures 2 to 4 The cleaning component 30 has a first end 31 and a second end 32 disposed opposite each other along the length of the receiving cavity 11, with the first end 31 disposed near the lateral opening 111. The direction along the distance from the first end 31 to the second end 32 (e.g.) Figure 2As shown on the X1 axis, the lateral opening 111 can expose the first end 31. That is, when viewed along the direction from the first end 31 to the second end 32, the end face of the first end 31 of the cleaning member 30 can fall completely into the field of view formed by the lateral opening 111, thereby achieving complete exposure of the end face of the first end 31.

[0182] In this embodiment, the cleaning device 100 has a housing 10 with a lateral opening 111 at one end along its length. A support component 20 is disposed within the housing 10, with its end near the lateral opening 111 being a free end. A cleaning component 30 is mounted on the support component 20, with its end near the lateral opening 111 fully exposed. This design eliminates the need for external end clips and installation space at the edge of the cleaning component 30, as is common in traditional structures. When the cleaning device 1000 moves along walls, baseboards, or furniture edges, the exposed end (i.e., the first end 31) of the cleaning component 30 can directly and fully approach these edge areas, significantly reducing cleaning blind spots caused by structural limitations. This improvement effectively enhances the cleaning effect in edge areas, especially in areas with obvious traditional cleaning blind spots such as the lower part of wall baseboards and around furniture legs, achieving more thorough cleaning and thus improving overall cleaning efficiency and user experience.

[0183] Please see Figure 2 In one embodiment of the present invention, along the length of the receiving cavity 11, at one end of the lateral opening 111, the outer edge of the housing 10 and / or the outer edge of the support assembly 20 extends beyond the outer edge of the first end 31. Specifically, in one embodiment, at one end of the lateral opening 111, the outer edge of the housing 10 extends beyond the outer edge of the first end 31 of the cleaning member 30, while the outer edge of the support assembly 20 does not extend beyond the outer edge of the first end 31. In another embodiment, the outer edge of the housing 10 does not extend beyond the outer edge of the first end 31 of the cleaning member 30, while the outer edge of the support assembly 20 extends beyond the outer edge of the first end 31. In other embodiments, such as Figure 2 As shown, the outer edge of the housing 10 and the outer edge of the support assembly 20 both extend beyond the outer edge of the first end 31.

[0184] It should be noted that, in this embodiment, although the outer edge of the housing 10 and / or the outer edge of the support component 20 structurally extend beyond the outer edge of the first end 31 of the cleaning component 30, during actual cleaning operations, when the cleaning device 100 approaches the edge areas of walls, furniture, etc., the cleaning component 30 can utilize its own elastic compression deformation characteristics to generate adaptive deformation. This deformation mechanism ensures that, in the final cleaning operation state, the outer edge of the first end 31 of the cleaning component 30 can preferentially contact the edge area to be cleaned, thereby achieving effective edge cleaning.

[0185] Furthermore, it should be understood that even if the cleaning component 30 fails to achieve preferential contact after compression and deformation under certain operating conditions, the first end 31 of the cleaning component 30 can still approach the edge area to be cleaned more closely than in the conventional structure because this embodiment eliminates the end-clamping structure at the lateral opening 111 in the conventional structure, thereby eliminating the inherent gap. Therefore, this embodiment can achieve a better edge-fitting cleaning effect than the conventional structure under different operating conditions.

[0186] This embodiment provides multiple implementation methods, such as extending the housing 10 beyond the edge, extending the support component 20 beyond the edge, or both beyond the edge, enabling the design to flexibly adapt to different product forms and cleaning scenario requirements, and providing more optimization space for product design. Compared with the cleaning blind spots that are inevitably formed by traditional end-clamping structures, this embodiment can still bring the cleaning component 30 closer to the edge area through an elastic deformation mechanism even when the edge of the housing 10 or the support component 20 extends beyond the cleaning edge, thereby achieving effective edge cleaning and improving the overall cleaning effect of the cleaning device 100.

[0187] Unlike the embodiments described above, in one embodiment of the present invention, along the length of the receiving cavity 11, at one end of the lateral opening 111, the outer edge of the housing 10 and / or the outer edge of the support assembly 20 are flush with the outer edge of the first end 31. Specifically, in one embodiment, the outer edge of the housing 10 is flush with the outer edge of the first end 31 of the cleaning member 30, while the outer edge of the support assembly 20 is not flush with the outer edge of the first end 31. In another embodiment, the outer edge of the support assembly 20 is flush with the outer edge of the first end 31, while the outer edge of the housing 10 is not flush with the outer edge of the first end 31. In other embodiments, both the outer edges of the housing 10 and the support assembly 20 are flush with the outer edge of the first end 31.

[0188] It should be noted that, in this embodiment, when describing the outer edge of the housing 10 and / or the outer edge of the support assembly 20 as "flush" with the outer edge of the first end 31 of the cleaning component 30, the "flush" state referred to should be understood as an approximate flush achieved within reasonable engineering installation and manufacturing tolerances. Specifically, this flush relationship allows for a certain range of error, which is determined by factors such as the manufacturing precision of the components, assembly clearances, and material properties.

[0189] In this embodiment, by setting the outer edge of the housing 10 and / or the outer edge of the support component 20 to be flush with the outer edge of the first end 31 of the cleaning component 30, the first end 31 of the cleaning component 30 is positioned as close as possible to the outermost edge of the housing 10 in terms of structural layout. This design ensures that when the cleaning device 100 is near the edge areas such as walls and furniture, the cleaning component 30 can effectively adapt to deformation under slight pressure due to its own elastic deformation characteristics. During this deformation process, the first end 31 of the cleaning component 30 can extend to the outside of the contour of the housing 10, preferentially making full contact with the edge area to be cleaned, thereby achieving a stable and reliable edge cleaning effect. At the same time, by providing multiple implementation methods such as the outer edge of the housing 10 being flush with the outer edge of the first end 31, the outer edge of the support component 20 being flush with the outer edge of the first end 31, or both being flush with the outer edge of the first end 31, this design can flexibly adapt to different product forms and cleaning scenario requirements, providing more optimization space for product design.

[0190] Unlike the above embodiments, in one embodiment of the present invention, when the cleaning member 30 contacts the surface to be cleaned to perform cleaning operations, along the length direction of the receiving cavity 11, at one end of the lateral opening 111, the outer edge of the first end 31 extends beyond the outer edge of the housing 10 and the outer edge of the support assembly 20.

[0191] This design ensures that the first end 31 of the cleaning component 30 better fits the edge area during cleaning operations, preventing the outer edge of the housing 10 or support component 20 from restricting the outer edge of the first end 31 of the cleaning component 30. Physical zero-distance contact with the edge area can be achieved before the cleaning component 30 undergoes compression deformation, thus fundamentally eliminating blind spots in edge cleaning caused by the housing 10 or support component 20. Simultaneously, due to the above structural design, a larger effective extension margin can be formed, enabling better deformation adaptation and fitting ability when facing irregular edge areas, thereby further improving the cleaning effect of the edge area.

[0192] In one embodiment of the present invention, when the cleaning component 30 is detached from the surface to be cleaned, the outer edge of the housing 10 and / or the outer edge of the support component 20 extend beyond the outer edge of the first end 31. Specifically, in one embodiment, the outer edge of the housing 10 extends beyond the outer edge of the first end 31, while the outer edge of the support component 20 does not extend beyond the outer edge of the first end 31. In another embodiment, the outer edge of the support component 20 extends beyond the outer edge of the first end 31, while the outer edge of the housing 10 does not extend beyond the outer edge of the first end 31. In other embodiments, both the outer edges of the housing 10 and the support component 20 extend beyond the outer edge of the first end 31.

[0193] It should be noted that, in the state where the cleaning component 30 is detached from the surface to be cleaned, if the outer edge of the housing 10 and / or the outer edge of the support component 20 extends beyond the outer edge of the first end 31 of the cleaning component 30, then in this embodiment, when the cleaning component 30 contacts the surface to be cleaned and performs cleaning operations, the specific positional relationship between the outer edge of the housing 10, the outer edge of the support component 20 and the outer edge of the first end 31 is not limited, and the structural form described in any of the above embodiments can be adopted.

[0194] In this embodiment, when the cleaning component 30 detaches from the surface to be cleaned, the outer edge of the housing 10 or the support assembly 20 extends beyond the outer edge of the first end 31 of the cleaning component 30. This structure effectively protects the first end 31 of the cleaning component 30 during non-cleaning operations, thereby reducing the possibility of accidental collisions or wear during handling or idle periods.

[0195] Unlike the previous embodiment, in one embodiment of the present invention, when the cleaning component 30 is detached from the surface to be cleaned, the outer edge of the first end 31 is flush with the outer edge of the housing 10 and / or the outer edge of the support component 20. Specifically, in one embodiment, the outer edge of the first end 31 is only flush with the outer edge of the housing 10, and not with the outer edge of the support component 20. In another embodiment, the outer edge of the first end 31 is only flush with the outer edge of the support component 20, and not with the outer edge of the housing 10. In other embodiments, the outer edge of the first end 31 is flush with both the outer edge of the housing 10 and the outer edge of the support component 20.

[0196] In this embodiment, when the cleaning component 30 detaches from the surface to be cleaned, the outer edge of the first end 31 is flush with the outer edge of the housing 10 and / or the support assembly 20. This configuration serves two purposes: firstly, in non-cleaning operation states, the flush structure effectively protects the first end 31 of the cleaning component 30, reducing the risk of damage due to collision or friction during handling or idle periods. Secondly, this structure ensures that the first end 31 of the cleaning component 30 is close to the outer contour of the housing 10 when not in cleaning operation, allowing it to more fully contact the edge area of ​​the surface to be cleaned through its own compression deformation after cleaning begins, thus ensuring effective cleaning of the edge area.

[0197] Unlike the previous embodiment, in one embodiment of the present invention, when the cleaning member 30 is detached from the surface to be cleaned, the outer edge of the first end 31 extends beyond the outer edge of the housing 10 and the outer edge of the support component 20.

[0198] This design allows for zero-distance physical contact between the outer edge of the first end 31 and the edge area before the cleaning component 30 is compressed and deformed, even when it is detached from the surface to be cleaned. This fundamentally eliminates blind spots in edge cleaning caused by the housing 10 or the support assembly 20. Furthermore, this design allows the cleaning component 30 to have greater effective extension allowance during cleaning operations, i.e., after compression and deformation. This provides better deformation adaptation and fit when facing irregular edge areas, further improving the cleaning effect on edge areas.

[0199] The support assembly 20 can be implemented in various ways. For example, it can be an integral structure, detachably connected to the housing 10, allowing the cleaning component 30 to be disassembled and replaced relative to the housing 10 by disassembling the entire support assembly 20. Alternatively, it can be composed of multiple separate structures, allowing the cleaning component 30 to be disassembled and replaced relative to the housing 10 by disassembling some of the structures. For clarity, the structure of the support assembly 20 will be described in detail below with reference to specific embodiments.

[0200] Optionally, please refer to Figures 5 to 7 In one embodiment of the present invention, the support assembly 20 includes a first support assembly 21 and a second support assembly 22. Along the length of the receiving cavity 11, one end of the first support assembly 21 is fixedly connected to the side of the housing 10 away from the lateral opening 111, and the other end of the first support assembly 21 is connected to one end of the second support assembly 22, with the other end of the second support assembly 22 forming a free end. The free end is not connected to the housing 10 and is in a suspended state.

[0201] Specifically, please refer to Figure 8 The housing 10 includes an end wall 13 and a side wall 12. The side wall 12 forms a receiving cavity 11. The end wall 13 is connected to one side of the receiving cavity 11 along its length. The other side of the receiving cavity 11 is open, forming a lateral opening 111. One end of the first support assembly 21 is fixedly connected to the end wall 13, and the connection method includes, but is not limited to, bolted connection, snap-fit ​​connection, etc. The other end of the first support assembly 21 is connected to one end of the second support assembly 22, and the connection method can be a detachable connection or a non-detachable connection, etc. The other end of the second support assembly 22 extends toward the side of the lateral opening 111 to form a free end.

[0202] Specifically, there are various implementation methods for the connection between the first support component 21 and the end wall 13 of the housing 10, and between the first support component 21 and the second support component 22. For example, in one embodiment, please refer to... Figures 5 to 7One end of the first support component 21 is fixedly connected to the end wall 13 of the housing 10, and the other end is rotatably connected to the second support component 22. The cleaning component 30 is fixedly installed on the second support component 22 and can rotate relative to the first support component 21 with the second support component 22. During cleaning operations, the second support component 22 drives the cleaning component 30 to rotate, achieving continuous cleaning. The rotation driving method of the second support component 22 includes, but is not limited to, the following two: one is an active driving method, in which the second support component 22 is actively driven to rotate by an additional driving component (such as a motor, or a motor in conjunction with a transmission mechanism), thereby driving the cleaning component 30 to perform cleaning operations. The other is a passive driving method, in which no independent driving source is set, but the second support component 22 is passively rotated by the friction force generated between the cleaning component 30 and the surface to be cleaned during the movement of the cleaning equipment 1000.

[0203] In another embodiment, one end of the first support component 21 is rotatably connected to the end wall 13 of the housing 10, and the other end is fixedly connected to the second support component 22. The cleaning component 30 is simultaneously fixedly supported on both the first support component 21 and the second support component 22. During cleaning operations, the entire support component 20 rotates relative to the housing 10 as a whole, thereby driving the cleaning component 30 to perform rotational cleaning operations. The rotation driving method of the first support component 21 includes, but is not limited to, the following two: one is an active driving method, in which the first support component 21 is actively driven to rotate by an additional driving component (such as a motor, or a motor in conjunction with a transmission mechanism), thereby driving the second support component 22 to rotate synchronously, so as to achieve continuous cleaning operations of the cleaning component 30. The other is a passive driving method, in which no independent driving source is provided, but during the movement of the cleaning device 1000, the first support component 21 and the second support component 22 are passively rotated synchronously by relying on the friction generated between the cleaning component 30 and the surface to be cleaned.

[0204] In this embodiment, along the length of the receiving cavity 11, one end of the first support component 21 is fixedly connected to the side of the housing 10 away from the lateral opening 111, and the other end is connected to one end of the second support component 22, while the other end of the second support component 22 forms a free end. This arrangement allows the entire support component 20 to form a cantilever support structure with one end fixed and the other end free. Compared to the solution of connecting the support component 20 to the housing 10 at its middle position, this structure sets the connection point between the support component 20 and the housing 10 on the outside of the cleaning component 30 away from the lateral opening 111, thereby avoiding interference of the connection structure with the installation and disassembly process of the cleaning component 30, thus improving the convenience of replacing the cleaning component 30. At the same time, this fixing method can also provide more optimization space for the overall layout of the receiving cavity 11, helping to reduce its size in the height direction and achieve a more compact structural design.

[0205] Please seeFigures 5 to 9 In one embodiment of the present invention, the cleaning component 30 is fixedly connected to the second support component 22. The fixed connection method can be adhesive connection, tension fit connection, or snap-fit ​​connection, etc. The second support component 22 is detachably connected to the first support component 21. The detachable connection method includes, but is not limited to, snap-fit ​​connection, bolt detachable connection, etc. The second support component 22 can drive the cleaning component 30 to move into or out of the receiving cavity 11 along the length direction of the receiving cavity 11 from the side opening 111. Specifically, when installing the cleaning component 30, the second support component 22, together with the cleaning component 30, can be moved into the receiving cavity 11 along the length direction of the receiving cavity 11 from the side opening 111, and the second support component 22 is connected to the first support component 21. When replacing the cleaning component 30, the second support component 22 can be removed from the first support component 21 and moved out along the length direction of the receiving cavity 11 from the side opening 111, thereby realizing the installation, removal, and replacement of the cleaning component 30.

[0206] With the above structural design, the second support component 22 and the cleaning component 30 together form a modular unit that can be disassembled as a whole. When the cleaning component 30 needs to be replaced, the modular unit can be removed from the first support component 21, thereby simplifying the operation process and improving maintenance efficiency. In addition, since the modular unit can be moved directly into or out along the length of the receiving cavity 11 through the lateral opening 111, linear and directional disassembly and assembly operations can be achieved. This design makes the installation and disassembly of the cleaning component 30 more intuitive and convenient, without the need for complex rotation or oblique operations. At the same time, since no additional disassembly space is required around the receiving cavity 11 (such as in the height direction of the body 200), it helps to improve the overall compactness of the cleaning equipment 1000 and facilitates the direct replacement of the cleaning component 30 while the cleaning device 100 is connected to the body 200.

[0207] In the aforementioned embodiments, the detachable connection structure between the second support component 22 and the first support component 21 makes it possible to replace the cleaning component 30. However, in actual operation, the disassembly and assembly process between the second support component 22 and the first support component 21 is still not convenient enough, and the operation steps are relatively cumbersome, resulting in low replacement efficiency and affecting user experience. Therefore, how to simplify the operation and improve the speed and convenience of disassembly and assembly has become a technical problem that urgently needs to be improved.

[0208] Based on this, in addition to the first support component 21 and the second support component 22 provided in the above embodiments, further please refer to... Figure 5 and Figure 8In one embodiment of the present invention, the first support component 21 includes a first connector 212, and the second support component 22 includes a second connector 221 and an operating component 222. The second connector 221 is linked with the operating component 222, and the operating component 222 is exposed through the lateral opening 111. The connection method between the first connector 212 and the second connector 221 can be a magnetic fixed connection, a snap-fit ​​fixed connection, or the like. The linkage between the second connector 221 and the operating component 222 can mean that the second connector 221 moves synchronously with the operating component 222, such as moving or rotating synchronously with the operating component 222, or that the operation of the operating component 222 can drive the second connector 221 to switch between specific states.

[0209] By operating the control element 222 through the lateral opening 111, the connection between the second connector 221 and the first connector 212 can be controlled (e.g., Figure 6 (as shown) or separated (such as) Figure 8 As shown in the diagram, this allows for the connection or separation between the second support component 22 and the first support component 21. It should be noted that the operation of the manipulator 222 can be performed manually or with the aid of tools through the side opening 111. The specific method can be flexibly selected based on the actual structural design and usage scenario.

[0210] Specifically, when the cleaning component 30 needs to be replaced, the user can operate the control component 222 (such as pulling, pushing, or rotating) through the side opening 111 to disengage the second connector 221 from the first connector 212. Then, the second support assembly 22, along with the cleaning component 30, is moved out along the length of the receiving cavity 11 to complete disassembly. When the cleaning component 30 needs to be installed into the receiving cavity 11, the second support assembly 22, carrying the cleaning component 30, is first moved into the receiving cavity 11 along its length until it reaches the predetermined position. Then, the control component 222 is operated through the side opening 111 to reconnect the second connector 221 to the first connector 212, thus fixing the second support assembly 22 to the first support assembly 21 and completing the installation and replacement of the cleaning component 30.

[0211] In this embodiment, the operating element 222 is directly exposed through the side opening 111. The user can easily control the connection or separation between the second connector 221 and the first connector 212 by operating the operating element 222 through this opening, thereby achieving quick assembly and disassembly between the second support assembly 22 and the first support assembly 21. Based on this structural design, when replacing the cleaning component 30, the second support assembly 22 can be moved out or installed entirely by operating the operating element 222 through the side opening 111, without disassembling other connecting structures. This significantly simplifies the operation process, shortens replacement time, and effectively improves the convenience of disassembling and replacing the cleaning component 30. Furthermore, since all operations are concentrated at the side opening 111, there is no need to reserve additional operating space or openings in other parts of the housing 10 or body 200, which helps to achieve an integrated and compact design of the overall structure, providing greater freedom for optimizing the product's appearance and internal layout.

[0212] To achieve a detachable connection between the first connector 212 and the second connector 221, various structural forms can be adopted. For example, in one embodiment, the first connector 212 and the second connector 221 can be detachably connected by a threaded engagement, that is, rotating the second connector 221 to tighten or loosen the threads, thereby completing the assembly and disassembly of the two. Of course, in other embodiments, the first connector 212 and the second connector 221 can also be detachably connected by a snap-fit ​​connection or other similar methods.

[0213] Optionally, please refer to Figure 8 , Figure 10 and Figure 11 In one embodiment of the present invention, the first connector 212 includes at least two opposing first latching portions 2121, and the second connector 221 includes at least two opposing second latching portions 2211, with one second latching portion 2211 corresponding to one first latching portion 2121. The first support component 21 and the second support component 22 are detachably connected through the latching engagement of the first latching portions 2121 and the second latching portions 2211.

[0214] The operating member 222 is slidably connected to the second connector 221 along the length of the receiving cavity 11, and has a first sliding position and a second sliding position. In the first sliding position, the two second locking portions 2211 can approach each other to allow the second locking portions 2211 to disengage from the corresponding first locking portions 2121. In the second sliding position, the two second locking portions 2211 can move away from each other to allow the second locking portions 2211 to engage and be fixed with the corresponding first locking portions 2121.

[0215] This snap-fit ​​connection structure allows the first snap-fit ​​part 2121 and the second snap-fit ​​part 2211 to quickly disengage or engage through simple pressing, rotating, or sliding actions, thus enabling convenient assembly and disassembly between the first support component 21 and the second support component 22. Consequently, users do not need to use additional tools when disassembling the second support component 22, such as when replacing the cleaning part 30, significantly improving the convenience of use and maintenance. Furthermore, this snap-fit ​​structure replaces traditional fastening methods such as screws and bolts, reducing the number of parts and assembly steps. This not only helps reduce overall costs and simplify the product structure but also avoids the inconvenience caused by tool dependence or the loss of small parts, further optimizing the user experience and the convenience of product maintenance.

[0216] The specific structures of the first engaging portion 2121 and the second engaging portion 2211 are not limited. For example, in one embodiment, the first engaging portion 2121 is a slot or hole formed on the first connecting member 212, and the second engaging portion 2211 is a hook or tongue formed on the second connecting member 221. When the operating member 222 is in the second sliding position, the hook or tongue is embedded in the corresponding slot or hole to achieve engagement and fixation; when the operating member 222 slides to the first sliding position, it can drive the hook or tongue to disengage from the slot or hole, thus releasing the connection. In another embodiment, the first engaging portion 2121 is an annular groove or a conical guide surface, and the second engaging portion 2211 is a claw or block that can expand and contract radially. In the second sliding position, the claw or block expands radially and engages in the annular groove or fits tightly against the conical guide surface; in the first sliding position, the operating member 222 forces the claw or block to contract radially, thereby withdrawing it from the first engaging portion 2121.

[0217] It should be noted that in this embodiment, the movement of the manipulator 222 between the first sliding position and the second sliding position can achieve the mutual movement of the two second engaging portions 2211, moving them closer or further apart. For example, in one embodiment, the manipulator 222 is an annular groove structure, and both second engaging portions 2211 pass through the annular groove structure. The inner wall of the annular groove structure is an inclined surface, and the outer wall of the second engaging portion 2211 is a vertical surface, with the vertical surface abutting against the inclined surface. During the sliding process of the manipulator 222, the relative movement of the two second engaging portions 2211 in the lateral direction (i.e., perpendicular to the sliding direction) is achieved through the abutment between the inclined surface and the vertical surface, thereby achieving mutual movement of the two portions closer or further apart. Of course, in other embodiments, the inner wall of the annular groove structure can also be a vertical surface, and the outer wall of the second engaging portion 2211 can be an inclined surface. With this configuration, the mutual movement of the two second engaging portions 2211 can also be achieved during the sliding process of the manipulator 222.

[0218] In another embodiment, the operating member 222 can also be configured as a push rod with a wedge-shaped protrusion, and the inner sides of the two second engaging portions 2211 are correspondingly provided with driving surfaces that cooperate with the inclined surfaces of the wedge-shaped blocks. When the operating member 222 slides along the length direction of the receiving cavity 11, the wedge-shaped blocks move accordingly. By pushing or releasing the driving surfaces of the second engaging portions 2211 with their inclined surfaces, the two second engaging portions 2211 can be forced to move away from or closer to each other in the lateral direction, thereby achieving engagement and fixation or separation from the first engaging portion 2121.

[0219] With the structural design in this embodiment, when replacing the cleaning component 30, the user only needs to slide the operating member 222 to the first sliding position to drive the two second locking parts 2211 to move closer together, releasing the locking relationship with the first locking part 2121. This process requires no tools and is simple and quick, effectively improving the disassembly efficiency between the second support component 22 and the first support component 21. Furthermore, the entire assembly and disassembly process is based on the mechanical linkage of sliding and locking, which not only avoids the common problems of stripping and wear in threaded connections but also eliminates the need for complex control and power supply modules required for electric drive. This structure is simple, reliable, and more suitable for applications requiring frequent replacement of the cleaning component 30.

[0220] Although there are various options for the specific implementation structure of the first latching portion 2121 and the second latching portion 2211, alternatively, please refer to Figure 10 and Figure 11 In one embodiment of the present invention, the first connecting member 212 includes a sleeve portion 2122, and a through groove is provided on the circumferential sidewall of the sleeve portion 2122, forming a first engaging portion 2121. The second connecting member 221 includes a rod portion 2212, and the second engaging portion 2211 is a locking block disposed on the rod portion 2212. The groove can be any shape such as a rectangular groove or a trapezoidal groove, and the shape of the locking block matches the shape of the groove. The rod portion 2212 can drive the second engaging portion 2211 to be inserted into the sleeve portion 2122, thereby realizing the engaging and fixing of the second engaging portion 2211 with the first engaging portion 2121.

[0221] The sleeve portion 2122 can be a cylindrical structure, a cuboid structure, or a polygonal structure, etc. Optionally, in this embodiment, the sleeve portion 2122 is an approximately cylindrical structure. The number of grooves can be equal to or unequal to the number of locking blocks. For example, in this embodiment, two locking blocks are provided, and the two locking blocks are approximately symmetrically arranged along the circumferential direction of the sleeve portion 2122. The number of grooves is greater than the number of locking blocks. Optionally, please refer to [link to relevant documentation]. Figure 10 and Figure 11 In this embodiment, four grooves are provided, which are arranged around the circumferential sidewall of the sleeve portion 2122, and any two grooves can be adapted to the two locking blocks.

[0222] If the number of grooves and locking blocks is the same, all locking blocks must be precisely aligned with all grooves simultaneously in the circumferential direction to achieve engagement. This stringent alignment requirement forces the user to repeatedly rotate and adjust during operation, thus reducing insertion efficiency. In contrast, this embodiment creates multiple positioning points for engagement in the circumferential direction by setting more grooves. This allows the locking blocks to complete the connection simply by rotating to any set of matching grooves, without needing to find a unique alignment point. Due to the multiple selectable alignment points and the small required rotation angle, the alignment error tolerance and engagement efficiency can be improved.

[0223] Specifically, the process by which the rod body 2212 drives the second locking part 2211 to move in and out of the sleeve part 2122 is as follows:

[0224] Connection Process: When the second engaging portion 2211 is inserted into the sleeve portion 2122, the rod portion 2212 moves toward the sleeve portion 2122. Depending on the initial position of the operating member 222, the insertion process can be implemented in two ways. In one way, the operating member 222 is in the second sliding position, and the two second engaging portions 2211 remain far apart. During insertion, the inner wall of the sleeve portion 2122 presses against the second engaging portions 2211, forcing them to move closer together, thus allowing them to smoothly enter the interior of the sleeve portion 2122. In another way, the operating member 222 is in the first sliding position, and the two second engaging portions 2211 are already close together, with the distance between their outermost edges less than the inner diameter of the sleeve portion 2122. Insertion in this state results in no pressing action between the inner wall of the sleeve portion 2122 and the second engaging portions 2211, allowing the second engaging portions 2211 to directly enter the sleeve portion 2122. When the second engaging portion 2211 moves to the interior of the sleeve portion 2122 and corresponds to the position of the first engaging portion 2121, the engaging and fixing can be achieved in any of the following ways: Method 1: The second engaging portion 2211 is released from the constraint of the inner wall of the sleeve portion 2122, and moves laterally away from each other and engages with the first engaging portion 2121 by its own elasticity or external drive. Method 2: The operating member 222 is slid to the second sliding position to release the restriction on the second engaging portion 2211, allowing the second engaging portion 2211 to move laterally away from each other and engage with the first engaging portion 2121 by its own elasticity or external drive.

[0225] Separation process: When the second locking part 2211 needs to be separated from the sleeve part 2122, the operating member 222 is first moved from the second sliding position to the first sliding position, driving the two second locking parts 2211 to move closer to each other, so that they disengage from the first locking part 2121. Then, the rod part 2212 is moved away from the sleeve part 2122, driving the second locking parts 2211 to move out of the sleeve part 2122, completing the separation operation.

[0226] This embodiment achieves a fixed connection by providing a grooved sleeve portion 2122 on the first connector 212 and a locking block on the rod portion 2212 of the second connector 221, utilizing the locking block's engagement with the groove. This structure allows the rod portion 2212 to drive the locking block along the length of the receiving cavity 11 into the sleeve portion 2122, completing the connection without the need for rotation, tightening, or auxiliary tools. This results in higher assembly efficiency and is more suitable for scenarios requiring frequent disassembly and reassembly of the cleaning component 30. Simultaneously, the engagement of the locking block and the groove creates bidirectional constraint in both the circumferential and radial directions, effectively resisting vibrations and torsional moments during cleaning operations, preventing accidental loosening of the second support component 22, and ensuring the stability and continuity of the cleaning process.

[0227] Optionally, in one embodiment of the present invention, when the second locking part 2211 is locked and fixed to the first locking part 2121, the operating member 222 is in the second sliding position, that is, the two second locking parts 2211 are in a state of being far apart from each other. When it is necessary to release the locking between the second locking part 2211 and the first locking part 2121, the operating member 222 switches from the second sliding position to the first sliding position, driving the two second locking parts 2211 to move closer to each other, so that the second locking part 2211 disengages from the first locking part 2121, thereby enabling the rod part 2212 to drive the second locking part 2211 to move out of the sleeve part 2122.

[0228] With this configuration, when the operating element 222 is in the second sliding position, the two second locking portions 2211 remain far apart from each other and stably engage with the first locking portion 2121, forming a mechanical locking connection. This prevents accidental loosening due to vibration or external force during cleaning operations, ensuring the reliability of the connection. Disassembly only requires switching the operating element 222 to the first sliding position, which drives the two second locking portions 2211 closer together to separate from the first locking portion 2121. This operation requires no complicated steps and is convenient and quick to implement, thus enabling rapid disassembly between the first connecting member 212 and the second connecting member 221, improving the maintenance efficiency of replacing the cleaning component 30.

[0229] To improve the smoothness of the second locking part 2211 entering the sleeve part 2122, optionally, please refer to Figure 10 and Figure 13In one embodiment of the present invention, the outer wall of the second engaging portion 2211 includes a guide slope 2213, and the sleeve portion 2122 includes a sleeve opening 21221 disposed on the side facing the second support assembly 22. The guide slope 2213 is used to guide the second engaging portion 2211 into the sleeve portion 2122 through the sleeve opening 21221. Specifically, the guide slope 2213 gradually expands and slopes from the side near the sleeve opening 21221 to the side away from the sleeve opening 21221, that is, the guide slope 2213 gradually extends in a direction away from each other along the insertion direction. The guide slope 2213 can adopt various structural forms, such as an inclined arc surface, an inclined plane, etc.

[0230] By setting a guide ramp 2213, in the initial stage when the second snap-fit ​​part 2211 contacts the sleeve opening 21221, the guide ramp 2213 can effectively guide and center the connection, automatically compensating for minor positional deviations during assembly, thus allowing the second snap-fit ​​part 2211 to smoothly slide into the sleeve part 2122. This design reduces the assembly difficulty of the second snap-fit ​​part 2211 entering the sleeve part 2122, and improves the installation efficiency and snap-fit ​​success rate between the second snap-fit ​​part 2211 and the first snap-fit ​​part 2121. At the same time, the guide ramp 2213, through its inclined structure, decomposes part of the axial force into a component force that drives the second snap-fit ​​part 2211 to produce radial elastic deformation during insertion. This force conversion effectively avoids rigid collision and direct friction between the second snap-fit ​​part 2211 and the edge of the sleeve opening 21221, making the entire insertion process more effortless and smooth, and significantly improving the operating feel and user experience.

[0231] Please see Figures 11 to 14 In one embodiment of the present invention, the second connecting member 221 further includes two rod portions 2212, each rod portion 2212 being correspondingly connected to a second engaging portion 2211. The operating member 222 is provided with a sliding groove 2221, one end of each of the two rod portions 2212 is slidably installed in the sliding groove 2221, and the other end extends toward the first engaging portion 2121 and connects to the second engaging portion 2211. The sidewall of the rod portion 2212 is provided with a straight section 22121 and an inclined section 22122, both of which are disposed toward the inner wall of the sliding groove 2221 and are able to abut against the inner wall of the sliding groove 2221. Along the extension direction of the rod body 2212, the straight section 22121 is located between the second snap-fit ​​section 2211 and the inclined section 22122, and from the side close to the straight section 22121 to the side away from the straight section 22121, the inclined section 22122 gradually extends inclined towards the side close to the inner wall of the slide groove 2221.

[0232] Of course, in other embodiments, the inclined section 22122 may be disposed between the straight section 22121 and the second snap-fit ​​portion 2211, and from one end near the straight section 22121 to the end away from the straight section 22121, the inclined section 22122 gradually extends towards the side near the inner wall of the slide groove 2221.

[0233] When the slide groove 2221 abuts against the straight section 22121, the two second engaging portions 2211 move away from each other, and at this time, the operating member 222 is in the second sliding position. When the slide groove 2221 abuts against the inclined section 22122, the slide groove 2221 presses against the sidewalls of the two rod portions 2212, causing the two second engaging portions 2211 to move closer to each other, and at this time, the operating member 222 is in the first sliding position.

[0234] In this embodiment, the cooperation between the sliding groove 2221 and the rod portion 2212 enables reliable switching between the open and closed states of the second locking portion 2211, thereby achieving the locking or disengagement between the second locking portion 2211 and the first locking portion 2121. In the locking state, the sliding groove 2221 cooperates with the straight section 22121 of the rod portion 2212, keeping the two rod portions 2212 far apart, thus ensuring that the two second locking portions 2211 are in the open position and securely locked with the first locking portion 2121. When it is necessary to disengage, the sliding operating member 222 causes the sliding groove 2221 to contact the inclined section 22122. The wall of the sliding groove 2221 presses against the inclined section 22122, using the inclined effect to force the two rod portions 2212 closer together, causing the second locking portions 2211 to move closer together, thereby achieving separation from the first locking portion 2121. This structure can transform the complex engagement and disengagement actions between the second engagement part 2211 and the first engagement part 2121 into a single linear sliding motion of the operating member 222. Therefore, the operation is intuitive and simple, and the operation is stable and reliable.

[0235] Please see Figure 12 and Figure 13 In one embodiment of the present invention, along the sliding direction of the slide groove 2221 relative to the rod portion 2212, a chamfered surface 2222 is provided at one end of the slide groove 2221 facing the inclined section 22122. The chamfered surface 2222 can guide the slide groove 2221 to slide from the straight section 22121 to the inclined section 22122. The chamfered surface 2222 can be a rounded surface, an oblique surface, etc.

[0236] By setting a chamfered surface 2222, the smoothness of the sliding transition of the slide 2221 between the straight section 22121 and the inclined section 22122 can be improved. When the operating member 222 is operated to slide the slide 2221 from the position mating with the straight section 22121 to the position mating with the inclined section 22122, the chamfered surface 2222 can act as a transition structure, pre-guiding the edge of the slide 2221 to smoothly detach from the straight section 22121 and enter the inclined section 22122, thereby effectively reducing the impact, jamming, or wear that may occur at the junction of the slide 2221 and the inclined section 22122. This not only improves the operating feel and makes the sliding process smoother and less strenuous, but also reduces the impact and wear of moving parts, extending the service life of the entire mechanism.

[0237] To ensure that the two second latching portions 2211 can remain stably separated from each other, thereby achieving a stable latching connection between the first latching portion 2121 and the second latching portion 2211, optionally, please refer to... Figure 12 and Figure 13 In one embodiment of the present invention, at least one first elastic member 23 is provided between the two rod portions 2212, and the elastic deformation direction of the first elastic member 23 is related to the relative movement direction of the two rod portions 2212 (e.g., ...). Figure 12 (As shown on the Z-axis). During the process of sliding from the inclined section 22122 to the straight section 22121 in the slide groove 2221, the first elastic element 23 releases elastic potential energy to push the two rod parts 2212 to separate from each other.

[0238] One, two, or more first elastic elements 23 may be provided. For example, in this embodiment, two first elastic elements 23 are provided, spaced apart along the length of the rod portion 2212. The first elastic element 23 may be a compression spring, a spring sheet, a torsion spring, or an elastic element made of other elastic materials. Optionally, in this embodiment, the first elastic element 23 is a compression spring. The two ends of the first elastic element 23 abut against two opposite sidewalls of the two rod portions 2212.

[0239] When the slide 2221 abuts against the inclined section 22122, that is, when the operating member 222 is in the first sliding position, the first elastic member 23 is compressed to store elastic potential energy. When the slide 2221 slides from the inclined section 22122 to the straight section 22121, that is, when the operating member 222 is in the second sliding position, the first elastic member 23 releases elastic potential energy and drives the two rod parts 2212 to separate from each other.

[0240] By setting the first elastic element 23, on the one hand, when the slide 2221 slides from the inclined section 22122 into the straight section 22121, the first elastic element 23 can instantly release elastic potential energy, automatically driving the two rod parts 2212 to move away from each other, thereby causing the second locking part 2211 to quickly and reliably reset to the open state. This automatic reset mechanism not only simplifies the operation, eliminating the need for manual adjustment of the second locking part 2211, but also ensures that the second locking part 2211 can form a stable and non-misaligned locking connection with the first locking part 2121. On the other hand, during the process of the first locking part 2121 entering the sleeve part 2122 and aligning with the second locking part 2211, the elastic opening force continuously applied by the first elastic element 23 can give the two second locking parts 2211 a certain "floating" space. When a misalignment is encountered, the second locking part 2211 can passively retract slightly to make way, and under the guidance of elastic force, it can automatically find and lock into the correct position, thereby reducing the docking accuracy requirements and improving the smoothness and fault tolerance of locking.

[0241] Please see Figure 9 , Figure 11 and Figure 12 In one embodiment of the present invention, the second support assembly 22 further includes a main body 24 and a mounting member 25. The main body 24 is used to support and fix the cleaning member 30. Specifically, the outer peripheral surface contour of the main body 24 is adapted to the cross-sectional contour of the cleaning member 30, the cleaning member 30 is sleeved on the outer periphery of the main body 24, and the outer peripheral surface of the main body 24 abuts against the inner wall of the cleaning member 30. Please refer to [link / reference]. Figure 12 and Figure 16 The mounting component 25 is fixedly connected to the main body 24 on the side facing the second snap-fit ​​portion 2211 and is provided with a guide groove 251. The fixed connection method can be bolted connection, snap-fit ​​connection, or integral molding connection, etc. The guide groove 251 is provided on the side of the slide groove 2221 away from the second snap-fit ​​portion 2211. The end of the rod portion 2212 away from the second snap-fit ​​portion 2211 passes through the slide groove 2221 and is slidably installed in the guide groove 251. The extension direction of the guide groove 251 is consistent with the extension direction of the slide groove 2221, and both are consistent with the relative movement direction of the two rod portions 2212. During the sliding of the slide groove 2221 along the rod portion 2212, the guide groove 251 can guide the two rod portions 2212 to move away from or closer to each other.

[0242] In this embodiment, the guide groove 251 provides guidance for the movement of the rod portion 2212. When the slide groove 2221 slides along the rod portion 2212 and drives the rod portion 2212 to move, the guide groove 251 can constrain the two rod portions 2212 to move closer or further apart along a preset path, effectively avoiding unexpected displacements such as deflection and jamming. This design helps ensure that the second locking portion 2211 and the first locking portion 2121 can achieve precise alignment and reliable locking, thereby improving locking efficiency and locking stability.

[0243] Please see Figure 15 and Figure 12 In one embodiment of the present invention, the rod portion 2212 facing the guide groove 251 includes a first stop portion 22123, a connecting portion 22124, and a second stop portion 22125 connected in sequence. The connecting portion 22124 slides through the guide groove 251. Along the length direction of the rod portion 2212, the first stop portion 22123 and the second stop portion 22125 are both located outside the guide groove 251 and can respectively stop at both ends of the guide groove 251. Specifically, the first stop portion 22123 abuts against the end face of one side of the guide groove 251 to form a stop on one side. The second stop portion 22125 abuts against the end face of the other side of the guide groove 251 to form a stop on the other side. As the two rod portions 2212 move closer or further apart, the first stop portion 22123 and the second stop portion 22125 can slide laterally along the end face of the guide groove 251 on the corresponding side.

[0244] By setting the first stop 22123 and the second stop 22125, not only can the installation positioning be formed in the extension direction of the rod 2212 to avoid the probability of the rod 2212 falling out of the guide groove 251 during operation, but also, through the contact between the first stop 22123 and the second stop 22125 and the two end faces of the guide groove 251, the probability of the rod 2212 deviating during operation can be further reduced, thereby further improving the guiding accuracy of the guide groove 251 for the rod 2212.

[0245] Please see Figure 12 , Figure 15 , Figure 19 and Figure 20In one embodiment of the present invention, a sliding cavity 241 is provided on the side of the main body 24 away from the mounting member 25. The sliding cavity 241 can be a cylindrical, cuboid, or polygonal cavity structure. Exemplarily, in this embodiment, the sliding cavity 241 is a cylindrical structure. The operating member 222 includes a sliding part 2223, a limiting part 2224, and an extension part 2225. The sliding part 2223 is slidably installed in the sliding cavity 241. One end of the extension part 2225 extends into the sliding cavity 241 and is fixedly connected to the sliding part 2223, and the other end extends toward the second engaging part 2211 and is connected to the limiting part 2224. The groove 2221 is provided in the limiting part 2224.

[0246] Specifically, the sliding part 2223 has an approximately disc-like structure and an outer peripheral wall that matches the inner wall of the sliding cavity 241. One end of the extension 2225 passes through the mounting member 25 and extends into the sliding cavity 241, where it is fixedly connected to the sliding part 2223. The fixed connection method can be an integral molding connection, a bolted connection, etc. The limiting part 2224 is disposed on the side of the extension 2225 away from the sliding part 2223 and is fixedly connected to the other end of the extension 2225. The fixed connection method includes a threaded connection, a snap-fit ​​connection, etc. The extension 2225 can be a cylindrical rod, a long strip, or other extended shapes. For example, in this embodiment, the extension 2225 is a cylindrical rod structure.

[0247] In this embodiment, the cooperation between the sliding part 2223 and the sliding cavity 241 provides precise guidance for the operation of the control member 222, ensuring the smooth operation of the control member 222. Simultaneously, by configuring the control member 222 as a sliding part 2223, a limiting part 2224, and an extension part 2225, the extension part 2225 connects the sliding part 2223 near the lateral opening 111 and the limiting part 2224 extending to one side of the second engaging part 2211. This achieves linkage between the groove 2221 on the limiting part 2224 and the sliding part 2223, which optimizes the force transmission path and improves the responsiveness of the linkage between the groove 2221 and the sliding part 2223.

[0248] Please participate Figures 17 to 19 In one embodiment of the present invention, a protruding structure 26 is provided on the inner wall of the sliding cavity 241 and / or the outer wall of the sliding portion 2223, and the inner wall of the sliding cavity 241 slides against the outer wall of the sliding portion 2223 through the protruding structure 26. In one embodiment, please refer to... Figure 17 and Figure 18The inner wall of the sliding cavity 241 is provided with a protruding structure 26, while the outer wall of the sliding part 2223 is not provided with a protruding structure 26. The outer wall of the sliding part 2223 slides against the protruding structure 26. One or more protruding structures 26 may be provided. The protruding structure 26 may be a plurality of protrusions, ridges, or blocks distributed on the inner wall of the sliding cavity 241. For example, in this embodiment, the protruding structure 26 is a plurality of ridge structures, which are arranged circumferentially around the inner wall of the sliding cavity 241, and the length direction of the plurality of ridges is consistent with the extension direction of the sliding cavity 241.

[0249] In another embodiment, the outer wall of the sliding portion 2223 may have a protrusion structure 26, while the inner wall of the sliding cavity 241 may not have a protrusion structure 26, and the inner wall of the sliding cavity 241 may slide against the protrusion structure 26. In other embodiments, the outer wall of the sliding portion 2223 may have a portion of the protrusion structure 26, and the inner wall of the sliding cavity 241 may have a portion of the protrusion structure 26. The outer wall of the sliding portion 2223 may slide against the portion of the protrusion structure 26, and the inner wall of the sliding cavity 241 may slide against the portion of the protrusion structure 26.

[0250] In this embodiment, by providing the protruding structure 26, the frictional conditions between the sliding part 2223 and the sliding cavity 241 can be improved, reducing the frictional resistance generated during the sliding of the sliding part 2223. This makes the pushing and pulling operation of the operating member 222 more effortless and smoother. At the same time, by providing the protruding structure 26, the dependence on the machining accuracy of a large area can be reduced, and wear can be concentrated on the protruding structure 26 itself, effectively avoiding gaps and shaking caused by uneven wear. This is conducive to maintaining the stability of long-term sliding operation between the sliding part 2223 and the sliding cavity 241.

[0251] Qing Reference Figure 15 , Figure 19 and Figure 20In one embodiment of the present invention, a second elastic member 27 is provided between the mounting member 25 and the limiting portion 2224, and the elastic deformation direction of the second elastic member 27 is consistent with the sliding direction of the slide groove 2221. During the sliding of the slide groove 2221 from the straight section 22121 to the inclined section 22122, the second elastic member 27 stores elastic potential energy. During the sliding of the slide groove 2221 from the inclined section 22122 to the straight section 22121, the second elastic member 27 releases elastic potential energy to drive the slide groove 2221 to slide. The second elastic member 27 can be a compression elastic member, a spring sheet, or an elastic member made of other elastic materials. One end of the second elastic member 27 can abut against the mounting member 25 or the main body 24, and the other end can abut against the extension portion 2225 or the limiting portion 2224. Exemplarily, in this embodiment, both ends of the second elastic member 27 abut against the main body 24 and the limiting portion 2224, respectively.

[0252] Specifically, during the sliding of the groove 2221 from the straight section 22121 to the inclined section 22122, the sliding part 2223 slides along the sliding cavity 241 toward the side closer to the lateral opening 111, thereby driving the groove 2221 on the limiting part 2224 to slide toward the side closer to the main body 24. At this time, the second elastic member 27 is compressed and stores elastic potential energy. During the sliding of the groove 2221 from the inclined section 22122 to the straight section 22121, the second elastic member 27 releases its elastic potential energy and drives the groove 2221 to slide toward the side away from the main body 24, thereby resetting the groove 2221 on the rod part 2212, that is, maintaining it in the position abutting against the straight section 22121. At the same time, the limiting part 2224 drives the sliding part 2223 to slide along the sliding cavity 241 toward the side away from the lateral opening 111.

[0253] In this embodiment, by providing a second elastic element 27, on the one hand, when the external force on one side of the sliding part 2223 is removed, the elastic force generated by the second elastic element 27 will drive the slide groove 2221 to automatically slide from the inclined section 22122 to the straight section 22121, thereby realizing the automatic reset of the operating member 222 and simplifying the operation process. On the other hand, when the slide groove 2221 slides from the straight section 22121 to the inclined section 22122, the second elastic element 27 is compressed and generates a reverse force. This force can ensure that the slide groove 2221 is always subjected to a resisting force along the sliding direction, thus suppressing the lateral swaying and offset of the operating member 222 during movement and improving the smoothness and stability of the operation of the operating member 222.

[0254] Please participate Figure 19 In one embodiment of the present invention, the second elastic member 27 is a compression spring. The second elastic member 27 is sleeved on the outer periphery of the extension 2225. One end of the second elastic member 27 abuts against the limiting part 2224 or the extension 2225, and the other end abuts against the main body 24. Please refer to [link to relevant documentation]. Figure 19In one embodiment, a boss 2227 may be provided on the side of the limiting portion 2224 facing the extension portion 2225, and the extension portion 2225 may be connected to the boss 2227. The end face of the boss 2227 may abut against the end of the second elastic member 27 away from the main body member 24. In another embodiment, the boss 2227 may be provided on the outer peripheral surface of the extension portion 2225 at the end near the limiting portion 2224, and the end of the second elastic member 27 away from the main body member 24 may abut against the end face of the boss 2227. Please refer to [link to relevant documentation]. Figure 16 A guide sleeve 242 is provided on the side of the main body 24 facing the mounting part. At least one end of the second elastic member 27 facing the main body 24 is disposed inside the guide sleeve 242 and can slide along the inner wall of the guide sleeve 242. By providing the guide sleeve 242, the deformation of the second elastic member 27 can be guided.

[0255] Using a compression spring as the second elastic element 27 serves two purposes. First, the compression spring can effectively accumulate and release elastic potential energy, providing a continuous and stable rebound force for the operating element 222. Second, as a standard component, the compression spring has the advantages of complete specifications, low procurement cost, and stable supply. This not only helps control product costs but also facilitates later maintenance and replacement.

[0256] Please see Figure 12 , Figure 17 , Figure 18 and Figure 19 In one embodiment of the present invention, the sliding cavity 241 has a cavity opening 2411 on the side facing the lateral opening 111, and the operating member 222 further includes a pull ring 2226, which is disposed on the side of the sliding part 2223 facing the cavity opening 2411. Pulling the pull ring 2226 can drive the sliding part 2223 to slide along the sliding cavity 241, thereby causing the slide groove 2221 to slide from the straight section 22121 to the inclined section 22122. The pull ring 2226 can be fixedly installed on the sliding part 2223, or it can be rotatably installed on the sliding part 2223 via a hinge or a rotating shaft. The specific shape of the pull ring is not limited, and it can be a circular ring, a U-shaped ring, a rectangular ring, etc.

[0257] By providing a pull ring 2226 on the sliding part 2223, the user can pull the pull ring 2226 to drive the slide groove 2221 from the position that mates with the straight section 22121 to the position that mates with the inclined section 22122, thereby quickly releasing the engagement between the second locking part 2211 and the first locking part 2121, thus improving the disassembly efficiency between the second locking part 2211 and the first locking part 2121. At the same time, the structure of the pull ring 2226 is more ergonomic, facilitating finger application, and allowing the user to easily pull the control part 222 without tools, which improves operational convenience and the overall user experience.

[0258] Please seeFigure 19 In one embodiment of the present invention, the pull ring 2226 is rotatably mounted on the sliding portion 2223, and the rotatable mounting method includes, but is not limited to, a rotatable connection with the rotating shaft 243. The pull ring 2226 has a first rotatable position and a second rotatable position relative to the sliding portion 2223. In the first rotatable position (e.g., ... Figure 19 and Figure 20 As shown, the pull ring 2226 unfolds towards the side closest to the cavity opening 2411 and can be pulled to drive the sliding part 2223 to slide. In the second rotation position, the pull ring 2226 folds towards the side opposite to the cavity opening 2411 to fit against the sliding part 2223. Specifically, in the second rotation position, the pull ring 2226 fitting against the sliding part 2223 means that the pull ring 2226 and the end face of the sliding part 2223 facing the cavity opening 2411 form a fitting relationship. This fitting relationship can be implemented in various ways, for example: the pull ring 2226 can be partially fitted against the end face of the sliding part 2223 facing the cavity opening 2411, or it can be completely fitted against the end face of the sliding part 2223 facing the cavity opening 2411, or it can be in a folded state that is infinitely close to the end face of the sliding part 2223 facing the cavity opening 2411. As long as the pull ring 2226 can be positioned at the second rotation position to save installation space and achieve a compact storage effect, it is acceptable.

[0259] In this embodiment, the pull ring 2226 is rotatably mounted on the sliding part 2223 and has two rotation positions. This configuration allows the pull ring 2226 to be switched to the first rotation position when the operating member 222 needs to be operated, unfolding it towards the cavity opening 2411 to provide the user with a clear point of force application, ensuring convenient and reliable operation. When the operating member 222 is not in operation, the pull ring 2226 can be switched to the second rotation position, folding it and fitting it against the surface of the sliding part 2223. This design helps reduce the space occupied by the pull ring 2226 when not in use, and effectively avoids problems such as snagging and impact that may be caused by the protrusion of the pull ring 2226 during storage, transportation, or operation. This reduces cleaning malfunctions caused by accidental pulling of the pull ring 2226 and improves the reliability of the cleaning device 100.

[0260] Please see Figure 19 and Figure 21 In one embodiment of the present invention, a third elastic element 28 is provided between the pull ring 2226 and the sliding portion 2223. When the pull ring 2226 is driven by an external force to rotate from a first rotational position to a second rotational position, the third elastic element 28 undergoes elastic deformation to store elastic potential energy. When the external force is removed, the third elastic element 28 releases the elastic potential energy to drive the pull ring 2226 to return from the second rotational position to the first rotational position. The third elastic element 28 may be a torsion spring, a spring sheet, or an elastic element made of other elastic materials.

[0261] By incorporating a third elastic element 28, when the external force applied to the pull ring 2226 is removed, the third elastic element 28 can immediately release its elastic potential energy, driving the pull ring 2226 to automatically return to the second rotational position that is in contact with the sliding part 2223. This achieves automatic reset of the pull ring 2226, reducing the need for manual reset operations. Simultaneously, when the pull ring 2226 is in a folded and fitted state, the clamping force applied by the third elastic element 28 can effectively suppress loosening or shaking of the pull ring 2226 caused by vibration during the operation of the cleaning component 30, thereby avoiding noise caused by rotational displacement or abnormal noise of the pull ring 2226.

[0262] Please see Figure 19 and Figure 21 In one embodiment of the present invention, the third elastic element 28 is a torsion spring. The pull ring 2226 is rotatably connected to the sliding part 2223 via a rotating shaft 243. The sliding part 2223 is provided with a protrusion 244. The third elastic element 28 is sleeved on the outer periphery of the rotating shaft 243, and the two connecting ends of the third elastic element 28 abut against the protrusion 244 and the pull ring 2226, respectively. During the process of the pull ring 2226 unfolding from the second rotation position to the first rotation position, its rotation will drive the third elastic element 28 to undergo torsional deformation, thereby storing elastic potential energy. When the pull ring 2226 is released, the third elastic element 28 will release its stored potential energy, driving the pull ring 2226 to automatically rotate in the opposite direction from the first rotation position, returning to the folded and stored second rotation position.

[0263] In this embodiment, a torsion spring is used as the third elastic element 28, and the two connecting ends of the third elastic element 28 abut against the protrusion 244 and the pull ring 2226, respectively. This design eliminates the need for a complex fixing structure and requires less installation space, thus simplifying the assembly process of the third elastic element 28 and facilitating a compact design at the pull ring 2226 position. Furthermore, the torsion spring primarily withstands torsional deformation during movement, and its material exhibits high fatigue strength and excellent wear resistance, enabling it to adapt to frequent rotational reset conditions and maintain a stable elastic restoring force over a long period.

[0264] Please see Figures 22 to 24 In one embodiment of the present invention, the cleaning component 30 is wound around the outer periphery of the support assembly 20, and the cleaning component 30 is a roller-type cloth. In other embodiments, the cleaning component 30 may also be a track-type cloth. The cleaning device 100 further includes a first drive assembly 40, which is disposed on the support assembly 20 and is used to drive the cleaning component 30 to rotate for cleaning operations. In other embodiments, the first drive assembly 40 may also be disposed on the housing 10, and the rotation output end 41 of the first drive assembly 40 drives the support assembly 20 to rotate.

[0265] In this embodiment, the cleaning component 30 is designed as a roller-type or track-type cloth wrapped around the outer periphery of the support component 20, and a corresponding first drive component 40 is configured to drive the cleaning component 30 to rotate. This satisfies the structural and functional requirements of conventional roller-type or track-type cloths. The cleaning component 30 achieves continuous and efficient wiping through rotational motion, which helps to expand the coverage area of ​​a single cleaning cycle and improve cleaning efficiency and effectiveness.

[0266] In the cleaning device 100, a corresponding drive assembly is usually required to achieve the rotational cleaning function of the roller or conveyor belt cleaning cloth. However, when the support assembly 20 adopts a cantilever structure with one end fixedly connected to the housing 10 and the other end being free, how to reasonably arrange the drive assembly within the limited installation space of the housing 10 and ensure stable and reliable power transmission between it and the cantilever support structure becomes a technical problem that urgently needs to be solved to ensure the compactness and smooth operation of the entire cleaning device 100.

[0267] Based on this, please refer to Figure 8 , Figure 22 and Figure 24 In one embodiment of the present invention, the support component 20 includes a first support component 21 and a second support component 22. One end of the first support component 21 is fixedly connected to the end of the housing 10 away from the lateral opening 111, and the other end of the first support component 21 is detachably connected to the second support component 22. The end of the second support component 22 away from the first support component 21 forms a free end. The cleaning component 30 is fixedly mounted on the first support component 21. The specific connection structure of the first support component 21 and the second support component 22 can be referred to the relevant description in the above embodiments, and will not be repeated here.

[0268] Please see Figure 24 The first support component 21 has a cavity 211, and the first drive component 40 is housed within the cavity 211 and fixedly connected to the first support component 21. The first drive component 40 has a rotating output end 41 extending to the outside of the cavity 211, and the second support component 22 is fixedly connected to the rotating output end 41. The first drive component 40 can be a motor, a combination of a motor and a reducer, a combination of a motor and a gear assembly, etc. Exemplarily, in this embodiment, the first drive component 40 is a motor, and the output shaft of the motor forms the rotating output end 41.

[0269] Specifically, the cavity 211 extends along the length of the first support component 21, and its cross-sectional shape can be circular, rectangular, or other shapes adapted to the external cross-section of the first drive component 40 to meet the installation space requirements of the first drive component 40. The fixing method of the first connector 212 to the rotary output end 41 is not limited. Optionally, in one embodiment, the first connector 212 has a shaft hole, and after the rotary output end 41 passes through the shaft hole, its protruding end is machined with external threads. The fixing connection between the two can be achieved by tightening the nut. This connection method has the characteristics of simple structure, convenient assembly and disassembly, and reliable connection. Of course, other fixing methods such as bolt connections can also be used to achieve the same function.

[0270] In this embodiment, a cavity 211 is provided inside the first support component 21 to accommodate the first drive component 40, achieving structural and functional integration. This design allows the first support component 21 to not only provide structural support but also to install and support the first drive component 40, thus making full use of its internal space and avoiding the first drive component 40 occupying additional external installation space. This not only improves the space utilization efficiency of the internal receiving cavity 11 of the housing 10 but also provides effective support for the compact and miniaturized design of the overall structure of the cleaning device 100. Furthermore, since the support component 20 adopts a cantilever structure, its side opening 111 is prone to tilting upwards during cleaning operations due to uneven force, affecting the cleaning effect. In this embodiment, by placing the first drive component 40 with a certain mass near the free end, it is equivalent to adding a counterweight to that side, effectively balancing the torque generated by the cantilever structure and reducing the tendency for the side opening 111 to tilt upwards. This counterweight design helps ensure that the cleaning component 30 maintains stable and sufficient contact pressure with the surface to be cleaned during operation, thereby improving the cleaning effect and operational stability.

[0271] Please see Figures 23 to 26 In one embodiment of the present invention, the first support component 21 includes a first cylindrical body 213 and a second cylindrical body 214. Along the length of the receiving cavity 11, one end of the second cylindrical body 214 is fixedly connected to the side of the housing 10 away from the lateral opening 111. The second cylindrical body 214 can be directly fixedly connected to the housing 10, or it can be indirectly fixedly connected to the housing 10 through other connecting members. The other end of the second cylindrical body 214 is fixedly engaged with the first cylindrical body 213 through a snap-fit ​​structure 215, forming a cavity 211. The first drive component 40 is fixedly installed on the first cylindrical body 213. The snap-fit ​​structure 215 can be a snap-fit ​​block and a snap-fit ​​groove structure, or it can be an elastic buckle or a quick-release locking mechanism, etc., as long as it can achieve reliable snap-fit ​​fixing between the first cylindrical body 213 and the second cylindrical body 214.

[0272] By employing a snap-fit ​​structure 215 to connect and fix the first cylinder 213 and the second cylinder 214, this design offers advantages over traditional bolt connections, including easier assembly, more stable connection, and no need for additional fasteners. This not only improves the assembly efficiency between the first cylinder 213 and the second cylinder 214 but also facilitates subsequent disassembly and maintenance, thereby providing convenience for the maintenance of the first drive assembly 40 within the cavity 211.

[0273] Optionally, please refer to Figures 27 to 29 In one embodiment of the present invention, the snap-fit ​​structure 215 includes a snap-fit ​​groove 2151 and a snap-fit ​​protrusion 2152 adapted to the snap-fit ​​groove 2151. One of the snap-fit ​​groove 2151 and the snap-fit ​​protrusion 2152 is disposed in the first cylindrical body 213, and the other is disposed in the second cylindrical body 214. The first cylindrical body 213 and the second cylindrical body 214 are fixedly connected by the snap-fit ​​of the snap-fit ​​groove 2151 and the snap-fit ​​protrusion 2152. The number of snap-fit ​​grooves 2151 and snap-fit ​​protrusions 2152 is not limited. Optionally, in this embodiment, two snap-fit ​​grooves 2151 and two corresponding snap-fit ​​protrusions 2152 are provided, and the two snap-fit ​​grooves 2151 are approximately symmetrically arranged along the circumference of the first cylindrical body 213.

[0274] Specifically, please refer to Figures 27 to 29 In one embodiment, a snap-fit ​​groove 2151 is disposed on the second cylindrical body 214, and a snap-fit ​​protrusion 2152 is disposed on the first cylindrical body 213. The snap-fit ​​groove 2151 is a through-hole structure extending radially through the second cylindrical body 214, and the snap-fit ​​protrusion 2152 is a protrusion structure protruding radially outward along the first cylindrical body 213. In another embodiment, the snap-fit ​​groove 2151 is disposed on the first cylindrical body 213, and the snap-fit ​​protrusion 2152 is disposed on the second cylindrical body 214. The snap-fit ​​groove 2151 is a through-hole structure extending radially through the first cylindrical body 213, and the snap-fit ​​protrusion 2152 is a protrusion structure protruding radially outward along the second cylindrical body 214.

[0275] The snap-fit ​​groove 2151 and snap-fit ​​protrusion 2152 used in this embodiment have a simple structure and are easy to directly process and form on the first cylinder 213 and the second cylinder 214, which helps to reduce mold complexity and manufacturing costs. At the same time, this snap-fit ​​connection method is stable and reliable, and can effectively transfer working loads. While ensuring the integrity of the structure, it also takes into account the balance between assembly efficiency and connection performance.

[0276] Please see Figures 27 to 29In one embodiment of the present invention, the snap-fit ​​structure 215 further includes a plug-in portion 2153 and a plug-in groove 2154 adapted to the plug-in portion 2153. One of the plug-in portion 2153 and the plug-in groove 2154 is disposed in the first cylindrical body 213, and the other is disposed in the second cylindrical body 214. The plug-in portion 2153 can be inserted into the plug-in groove 2154 along the length direction of the first cylindrical body 213 to guide and position it when the snap-fit ​​groove 2151 and the snap-fit ​​protrusion 2152 snap together. The number of plug-in portions 2153 and plug-in grooves 2154 is not limited. Optionally, in this embodiment, two plug-in portions 2153 and two plug-in grooves 2154 are provided, and the two plug-in portions 2153 are spaced apart along the circumferential direction of the first cylindrical body 213.

[0277] Please see Figures 27 to 29 In one embodiment, the second cylindrical body 214 has a plug-in portion 2153 on the side facing the first cylindrical body 213, and the plug-in portion 2153 extends toward the first cylindrical body 213. The first cylindrical body 213 is correspondingly provided with a plug-in groove 2154 recessed radially inward. When the plug-in portion 2153 is inserted into the plug-in groove 2154, the bottom wall of the groove 2154 abuts against the inner wall of the plug-in portion 2153 along the radial direction of the first cylindrical body 213, and the side wall of the groove 2154 simultaneously forms abutment contact with the side wall of the plug-in portion 2153 along the circumferential and axial directions of the first cylindrical body 213, thereby achieving positioning of the first cylindrical body 213 and the second cylindrical body 214 in multiple directions, including radial, axial, and circumferential. Specifically, a snap-fit ​​protrusion 2152 is provided on the bottom wall of the plug-in groove 2154, and a snap-fit ​​groove 2151 is provided on the plug-in portion 2153. During the process of inserting the connector 2153 into the connector slot 2154, the guide snap protrusion 2152 gradually inserts into the snap slot 2151.

[0278] Of course, in another embodiment, the first cylindrical body 213 may have a plug-in portion 2153 on the side facing the second cylindrical body 214, and the second cylindrical body 214 may have a corresponding plug-in groove 2154 recessed radially inward. The plug-in groove 2154 and the plug-in portion 2153 adopt the same structural configuration as in the above embodiment.

[0279] This embodiment further optimizes the assembly process of the first cylinder 213 and the second cylinder 214 by adding mutually compatible insertion parts 2153 and insertion slots 2154 to the snap-fit ​​structure 215. Before the snap-fit ​​protrusion 2152 engages with the snap-fit ​​slot 2151, the insertion part 2153 can be pre-inserted into the insertion slot 2154 along the length of the first cylinder 213, forming axial guidance and radial limiting, effectively guiding the snap-fit ​​slot 2151 and the snap-fit ​​protrusion 2152 to quickly align, avoiding misalignment or skew during the snap-fit ​​process. Therefore, this structural component can improve the snap-fit ​​assembly accuracy and snap-fit ​​connection efficiency between the first cylinder 213 and the second cylinder 214, and can also enhance the overall connection rigidity and torsional stability between the first cylinder 213 and the second cylinder 214 through the insertion fit, so that the snap-fit ​​structure 215 can still maintain reliable connection performance under complex working conditions.

[0280] Please see Figure 27 and Figure 30 In one embodiment of the present invention, a bottom wall 2131 is provided at the end of the first cylinder 213 away from the second cylinder 214, and the bottom wall 2131 is provided with a mounting hole 2132. The first drive assembly 40 is fixed to the bottom wall 2131, and the rotation output end 41 extends out through the mounting hole 2132. The side of the first drive assembly 40 facing the bottom wall 2131 has a mounting end face 42, and a sealing member 60 is provided between the mounting end face 42 and the bottom wall 2131 to achieve a seal between the mounting end face 42 and the bottom wall 2131.

[0281] Because the first cylinder 213 and the second cylinder 214 are installed near the cleaning component 30, dirt can easily penetrate into the cavity 211 formed by the first cylinder 213 and the second cylinder 214 during cleaning operations, causing contamination of the first drive assembly 40. In this embodiment, a sealing element 60 is provided at the mounting hole 2132, effectively achieving a reliable seal at the mounting location of the first drive assembly 40. This sealing element 60 can prevent external dirt from entering the cavity 211 formed by the first cylinder 213 and the second cylinder 214 through the gap in the mounting hole 2132, thereby reducing the risk of contamination to the first drive assembly 40 and ensuring its long-term stable operation during cleaning operations.

[0282] Please see Figures 22 to 24In one embodiment of the present invention, the first support component 21 further includes a mounting base 216. The mounting base 216 is detachably connected to the end of the second cylinder 214 away from the first cylinder 213, and is fixedly connected to the side of the housing 10 away from the lateral opening 111. Specifically, one end of the mounting base 216 is detachably connected to the end of the second cylinder 214 away from the first cylinder 213, and the detachable connection method includes snap-fit ​​connection, bolt connection, etc. The other end of the mounting base 216 is fixedly connected to the end wall 13 of the housing 10. The fixed connection method includes snap-fit ​​fixation or bolt fixation connection, etc.

[0283] This embodiment effectively optimizes the connection performance between the first support component 21 and the housing 10 by designing the mounting base 216 and the second cylinder 214 as separate structures with a detachable connection. Since the first support component 21 adopts a cantilever installation structure, its root connection to the housing 10 needs to withstand a large bending moment, requiring high material strength. The separate design allows the mounting base 216 to be independently made of high-strength materials to fully meet structural load-bearing requirements, while the second cylinder 214 can use lower-cost or lighter ordinary materials. This combination ensures connection reliability while balancing manufacturing cost and lightweight requirements.

[0284] Please see Figure 22 In one embodiment of the present invention, the housing 10 further includes a side wall 12 and an end wall 13. The end wall 13 is disposed at the end of the receiving cavity 11 away from the lateral opening 111, and together with the side wall 12, forms the receiving cavity 11. The mounting base 216 is fixedly connected to the end wall 13, and the thickness of the end wall 13 is greater than the thickness of the side wall 12.

[0285] In this embodiment, the thickened end wall 13 design achieves localized reinforcement of the critical stress-bearing areas of the shell 10. This design not only improves the support stiffness and strength of the end wall 13 area, enabling it to reliably withstand the bending moment and vibration load transmitted by the first support component 21 and meet the load-bearing requirements, but also avoids increasing the overall wall thickness of the shell 10 to improve local strength. This allows for a reasonable distribution of materials and a lightweight design while ensuring the structural reliability of the shell 10.

[0286] When the cleaning component 30 is supported by both the first support component 21 and the second support component 22, the cleaning component 30 relies on both support components simultaneously. Driven by the first drive component 40, the second support component 22 rotates the cleaning component 30 relative to the first support component 21. This type of cross-component transmission structure often faces inherent challenges in actual operation, such as long transmission paths, gaps between support points, and inconsistent stiffness between different components. These factors can easily lead to asynchronous rotation between the second support component 22 and the first support component 21, and between the cleaning component 30 and the first support component 21. This can cause the cleaning component 30 to slip locally or twist and deform overall during operation, disrupting the uniform contact and stable pressure distribution between it and the cleaning surface, ultimately affecting the cleaning effect and accelerating component wear. Therefore, achieving synchronized movement between multiple support points is a key technical issue for improving the operational reliability and cleaning effect of this type of cleaning device 100.

[0287] To improve the above issues, optionally please refer to Figure 22 , Figure 32 and Figure 34 In one embodiment of the present invention, a first support structure 71 is provided at the end of the first support component 21 away from the second support component 22, and the first support structure 71 is sleeved on the outer periphery of the first support component 21. That is, the first support structure 71 is provided on the side of the first support component 21 near the end wall 13 of the housing 10. The cleaning component 30 is rotatably supported on the outer periphery of the first support component 21 by means of the first support structure 71. There may be one first support structure 71, or there may be multiple first support structures 71 spaced apart along the length direction of the first support component 21. For example, in this embodiment, there is one first support structure 71.

[0288] The first support structure 71 can have various structural forms. For example, in one embodiment, the first support structure 71 can be a slewing bearing, with its inner ring fixedly connected to the outer peripheral surface of the first support assembly 21, and its outer ring fixedly supported on the inner wall of the cleaning component 30. Rotation of the slewing bearing achieves a rotatable connection between the cleaning component 30 and the first support assembly 21. In another embodiment, the first support structure 71 can also be a slewing sleeve structure, with its inner wall rotatably connected to the outer peripheral surface of the first support assembly 21 via a clearance fit through a shaft hole, and its outer wall fixedly supported on the inner wall of the cleaning component 30. Rotation of the slewing sleeve relative to the first support assembly 21 achieves a rotatable connection between the cleaning component 30 and the first support assembly 21.

[0289] In this embodiment, a first support structure 71 is provided, allowing the cleaning component 30 to be rotatably supported on the outer periphery of the first support assembly 21. This design avoids direct contact and friction between the inner wall of the cleaning component 30 and the outer peripheral surface of the first support assembly 21, thereby mitigating the impact of uneven friction on synchronous rotation performance and reducing the risk of twisting or deformation of the cleaning component 30, thus ensuring the stability and reliability of the cleaning effect. Furthermore, when replacing the cleaning component 30, the first support structure 71 effectively reduces the frictional resistance when the first support assembly 21 is inserted into the cleaning component 30, allowing it to enter more smoothly and improving the replacement efficiency of the cleaning component 30.

[0290] Please see Figure 33 and Figure 34 In one embodiment of the present invention, the first support structure 71 includes a rotating member 711 and a support sleeve 712. The support sleeve 712 is fixedly sleeved on the outer periphery of the rotating member 711, and the rotating member 711 is rotatably mounted on the outer periphery of the first support assembly 21. The support sleeve 712 abuts against the inner wall of the cleaning member 30, and the rotation of the cleaning member 30 causes the support sleeve 712 to rotate relative to the first support assembly 21. The rotating member 711 may be a slewing bearing, a self-lubricating bushing, etc. For example, in this embodiment, the rotating member 711 is a slewing bearing. The inner ring of the slewing bearing is fixedly connected to the outer periphery of the first support assembly 21, and the outer ring of the slewing bearing is fixedly connected to the inner wall of the support sleeve 712. The outer wall of the support sleeve 712 abuts against and is fixedly fixed to the inner wall of the cleaning member 30. When the cleaning member 30 rotates, it can support the sleeve 712 to rotate synchronously, and the support sleeve 712 is rotatably connected to the first support assembly 21 through the slewing bearing.

[0291] This embodiment achieves functional separation of friction transmission and rotational support by employing a split design for the rotating component 711 and the support sleeve 712. The support sleeve 712 is specifically responsible for friction transmission with the inner wall of the cleaning component 30, and can be made of high-friction coefficient materials such as rubber or polyurethane to significantly enhance transmission friction and effectively prevent slippage. The rotating component 711 focuses on providing stable rotational support, and can be made of low-friction coefficient wear-resistant materials such as POM or nylon, or directly use a rotary bearing to ensure smooth and durable rotation. Therefore, the above-mentioned split structure allows for targeted optimization of the performance of each component, avoiding the increased design difficulty of a single component having to accommodate multiple performance aspects, thus resulting in better design adaptability.

[0292] Please see Figure 33 and Figure 34In one embodiment of the present invention, the outer peripheral surface of the support sleeve 712 includes a first support surface 7121 and a first guide surface 7122. The first support surface 7121 is used to abut against the inner wall of the cleaning component 30, and the first guide surface 7122 is connected to the side of the first support surface 7121 near the second support assembly 22, and is used to guide the cleaning component 30 to be sleeved on the first support surface 7121. The first support surface 7121 can be a full-circumferential annular structure, or it can be a support surface structure formed by a combination of multiple spaced partial surfaces. Optionally, in this embodiment, the first support surface 7121 is a full-circumferential annular structure. The first guide surface 7122 can be a frustum-shaped structure, with the larger diameter end of the frustum-shaped surface connected to the first support surface 7121, and the smaller diameter end of the frustum-shaped surface extending toward the side away from the first support surface 7121. The first guide surface 7122 can also be a combination of multiple spaced partial inclined surfaces to form the first guide surface 7122.

[0293] By providing a first guide surface 7122, the cleaning component 30 can automatically center and guide the assembly during its insertion into the first support component 21. This design effectively reduces insertion resistance during assembly, preventing scratches or deformation of the inner wall of the cleaning component 30 due to forced insertion. This improves the installation efficiency of the cleaning component 30 and the first support component 21 and protects the structural integrity of the cleaning component 30.

[0294] Please see Figure 33 and Figure 34 In one embodiment of the present invention, a plurality of first protrusions 7123 are provided on the outer periphery of the support sleeve 712. The plurality of first protrusions 7123 are spaced apart along the circumference of the support sleeve 712. The outer side wall of the first protrusion 7123 includes a first inclined wall surface 7125. The first inclined wall surfaces 7125 of the plurality of first protrusions 7123 together form a first guide surface 7122. One end of the first inclined wall surface 7125 is connected to the first support surface 7121, and the other end extends toward the side away from the first support surface 7121 and is inclined toward the side closer to the axis of the first support structure 71. By providing the first protrusions 7123, the first guide surface 7122 can form a plurality of local surfaces spaced apart along the circumferential direction. In this way, during the insertion of the cleaning component 30 into the first guide surface 7122, the frictional resistance of insertion can be reduced, and the smoothness of insertion of the cleaning component 30 can be further improved.

[0295] Please see Figure 23 ,picture Figure 32 , Figure 35 and Figure 36In one embodiment of the present invention, a second support structure 72 is fixedly connected to the rotating output end 41, and the outer peripheral surface of the second support structure 72 at least partially abuts against the inner wall of the cleaning component 30. The second support structure 72 may be directly fixedly connected to the rotating output end 41, or it may be indirectly fixedly connected through other components connected to the rotating output end 41. The manner in which the outer peripheral surface of the second support structure 72 abuts against the inner wall of the cleaning component 30 is not limited. For example, the outer peripheral surface of the second support structure 72 may form a full circumferential annular contact with the inner wall of the cleaning component 30, or it may form a plurality of circumferentially distributed partial contact surface structures.

[0296] By fixing a second support structure 72 to the rotary output end 41, and ensuring that at least part of the outer circumferential surface of the second support structure 72 abuts against the inner wall of the cleaning component 30, a support for the cleaning component 30 is formed at the location of the rotary output end 41. Adding a support point at the corresponding location of the rotary output end 41 effectively constrains the radial runout of the cleaning component 30 at that point, forming a distributed support structure across regions. This improves the overall stability of the cleaning component 30 during high-speed rotation and reduces vibration and sway. Simultaneously, the abutting contact between the second support structure 72 and the inner wall of the cleaning component 30 increases the transmission friction contact area and force, effectively preventing relative slippage between the cleaning component 30 and the rotary output end 41, ensuring rotational synchronization, and avoiding uneven cleaning or reduced efficiency due to slippage.

[0297] For reference Figure 32 and Figure 36 In one embodiment of the present invention, the second support structure 72 is fixedly connected to the first connector 212. Specifically, the second support structure 72 is arranged around the outer periphery of the first connector 212. The fixed connection between the two can be integral injection molding or snap-fit ​​fixing, etc. In this embodiment, snap-fit ​​fixing is preferred to connect the second support structure 72 and the first connector 212. This design allows the second support structure 72 to be set as an independent component on the first connector 212, thereby facilitating the selection of materials for the first connector 212 and the second support structure 72 according to functional requirements. Specifically, the first connector 212 needs to have high connection and support strength to effectively transmit the output torque of the rotating output end 41 to the second support assembly 22; while the second support structure 72 needs to have excellent friction performance to ensure stable friction with the inner wall of the cleaning component 30 and reduce the risk of slippage.

[0298] Please see Figure 35 and Figure 36The outer peripheral surface of the second support structure 72 includes a second support surface 721 and a second guide surface 722. The second support surface 721 is used to abut against the inner wall of the cleaning component 30, and the second guide surface 722 is connected to the side of the second support surface 721 facing the first support assembly 21, and is used to guide the cleaning component 30 to be fitted onto the second support surface 721. The second support surface 721 can be an annular surface that can match the inner wall of the cleaning component 30, or it can be a plurality of partial support surface structures arranged around the circumferential direction of the cleaning component 30.

[0299] The second guide surface 722 can be a frustum-shaped structure, with the larger diameter end of the frustum-shaped surface connected to the second support surface 721, and the smaller diameter end extending towards the side away from the second support surface 721. The second guide surface 722 can also be a combination of multiple spaced partial slopes to form the second guide surface 722.

[0300] By providing a second guide surface 722, the cleaning component 30 can automatically center and guide the assembly during its insertion into the second support structure 72. This design effectively reduces insertion resistance during assembly, preventing scratches or deformation of the inner wall of the cleaning component 30 due to forced insertion. This improves the smoothness of insertion between the cleaning component 30 and the second support structure 72, thereby further enhancing the efficiency of installation and replacement of the cleaning component 30.

[0301] Please see Figure 35 and Figure 36 In one embodiment of the present invention, a plurality of second protrusions 723 are provided around the outer periphery of the second support structure 72. The outer sidewall of the second protrusion 723 includes a second inclined wall surface 7232, and the second inclined wall surfaces 7232 of the plurality of second protrusions 723 together form a second guide surface 722. One end of the second inclined wall surface 7232 is connected to the second support surface 721, and the other end extends toward the side away from the second support surface 721 and is inclined toward the side closer to the axis of the second support structure 72. By providing the second protrusions 723, the second guide surface 722 can form a plurality of local surfaces spaced apart in the circumferential direction. In this way, during the insertion of the cleaning component 30 into the second guide surface 722, the frictional resistance of insertion can be reduced, and the smoothness of insertion of the cleaning component 30 can be further improved.

[0302] Please see Figure 36In one embodiment of the present invention, the outer wall of the second protrusion 723 further includes a straight wall surface 7231, which is connected to the side of the second inclined wall surface 7232 opposite to the first support assembly 21. The straight wall surfaces 7231 of the multiple second protrusions 723 together form the second support surface 721. It should be noted that in this embodiment, the straight wall surface 7231 refers to a planar structure whose extension direction is substantially parallel to the insertion direction of the cleaning component 30. By providing a straight wall surface 7231 on the second protrusion 723, the second support surface 721 can form multiple local surfaces spaced apart in the circumferential direction. In this way, during the insertion of the cleaning component 30 into the second support surface 721, the frictional resistance of insertion can be reduced, further improving the smoothness of insertion of the cleaning component 30 into the second support structure 72.

[0303] Please see Figure 10 , Figure 37 , Figure 38 and Figure 40 In one embodiment of the present invention, at least one positioning groove 2123 is provided on the outer periphery of the first connecting member 212 and / or the second support structure 72, and at least one positioning block 33 is correspondingly provided on the inner wall of the cleaning member 30. The positioning block 33 is correspondingly engaged in the positioning groove 2123 to achieve positioning of the first connecting member 212 and the cleaning member 30 in the circumferential direction. In one embodiment, please refer to... Figure 10 The first connector 212 has a positioning groove 2123 on its outer periphery. In another embodiment, the second support structure 72 has a positioning groove 2123 on its outer periphery. In other embodiments, there may be multiple positioning grooves 2123, with some positioning grooves 2123 located on the outer periphery of the first connector 212 and some positioning grooves 2123 located on the outer periphery of the second support structure 72.

[0304] Optionally, in this embodiment, please refer to Figure 10 Multiple positioning grooves 2123 are provided, and the multiple positioning grooves 2123 are arranged around the outer periphery of the first connecting member 212. Specifically, the first connecting member 212 includes multiple support ribs 217, which are arranged around the outer periphery of the sleeve portion 2122 to enhance the support strength and rigidity of the sleeve portion 2122. A positioning groove 2123 is formed between adjacent support ribs 217. Multiple positioning blocks 33 are provided, and one positioning block 33 corresponds to one positioning groove 2123. The positioning block 33 can be integrally formed on the inner wall of the cleaning member 30, or it can be fixed to the inner wall of the cleaning member 30 by fasteners such as lifting bolts. When the cleaning member 30 is installed, the positioning block 33 on the inner wall of the cleaning member 30 can be engaged with the corresponding positioning groove 2123 along the insertion direction, thereby realizing the positioning of the cleaning member 30 with the second support member and the first connecting member 212 at least in the circumferential direction.

[0305] By setting the positioning groove 2123 and the positioning block 33, and making the positioning block 33 and the positioning groove 2123 interlock, a direct torque transmission path is formed between the first connector 212 and the cleaning component 30. Since the first connector 212 is connected to the rotation output end 41 of the first drive assembly 40, this design can effectively transmit the output torque to the cleaning component 30, thereby reducing the probability of the cleaning component 30 slipping relative to the rotation output end 41 in the circumferential direction, and further improving the stability and reliability of the cleaning component 30 during operation.

[0306] like Figure 2 As shown, because the side of the support component 20 closest to the lateral opening 111 is a free end when installed inside the housing 10, the structural support strength in this area is relatively weak. This installation method easily leads to an uneven distribution of the overall stiffness of the support component 20, making it difficult for the cleaning element 30 installed on the support component 20 to maintain a uniform pressure distribution when pressing against the surface to be cleaned. Especially when performing cleaning tasks such as mopping that require large and uniform downward pressure, the insufficient support at the free end will further reduce the actual pressure exerted by the cleaning element 30 on the surface to be cleaned at the corresponding position, thus causing incomplete cleaning and inconsistent results in this area, ultimately affecting the overall cleaning performance of the cleaning equipment 1000.

[0307] To improve the above issues, please refer to Figure 4 and Figure 41 In one embodiment of the present invention, the receiving cavity 11 has a bottom opening 112 on the side facing the cleaning surface. The bottom opening 112 is used to expose the cleaning component 30 for cleaning operations. In this embodiment, the cleaning component 30 is a roller-type wiping cloth. In other embodiments, the cleaning component 30 may also be a track-type wiping cloth. The housing 10 has an abutment 14 on the side near the lateral opening 111. The abutment 14 is aligned along the height direction of the cleaning device 100 (e.g., ...). Figure 45 (As shown by the Z-axis) is at least partially located above the bottom opening 112 (as shown by...) Figure 45 and Figure 48 (As shown), it is used to apply a force toward the surface to be cleaned to the cleaning component 30. The abutment 14 can be integrally formed with the inner wall of the housing 10, or it can be fixedly installed on the inner wall of the housing 10.

[0308] The specific structure of the abutment 14 is not limited. It can be an arc-shaped plate or arc-shaped block structure that conforms to the shape of the inner wall of the housing 10, or a protruding structure of any shape such as a rectangular block or rectangular strip. The number of abutment 14 can be one or more, and multiple abutment 14 can be arranged at intervals along the length of the receiving cavity 11 on one side near the lateral opening 111.

[0309] It should be noted that the direction of the force exerted by the abutment member 14 is not limited to a single direction. In some embodiments, it may only apply a force toward the surface to be cleaned to the cleaning member 30; in other embodiments, it may also apply a force in other directions simultaneously. This embodiment does not limit this.

[0310] In this embodiment, an abutment member 14 is provided on the side of the housing 10 near the lateral opening 111, above the bottom opening 112. This abutment member 14 can apply a force to the cleaning member 30 toward the surface to be cleaned. This arrangement allows the cleaning member 30 to obtain effective auxiliary downward pressure on the free end side of the support assembly 20, compensating for the pressure loss caused by insufficient support stiffness of the support assembly 20 on the free end side. This improves the problems of uneven cleaning pressure distribution and poor cleaning effect at the free end, ensuring the overall cleaning performance of the cleaning device 1000.

[0311] Based on the design of providing the abutment member 14 in the housing 10, further please refer to... Figure 42 , Figure 43 and Figure 45 In one embodiment of the present invention, the cleaning device 100 further includes a squeegee structure 15, which extends at least partially into the receiving cavity 11 and contacts the cleaning member 30 to squeegee off the sewage on the cleaning member 30. The force applied by the abutment member 14 to the cleaning member 30 can generate a force on the cleaning member 30 toward the side of the squeegee structure 15.

[0312] It should be noted that when the squeegee structure 15 and the cleaning component 30 come into contact, they can be in an interference fit, forming mutual compression, or they can only be in surface contact without compression, as long as it ensures that the cleaning structure can scrape off the wastewater on the cleaning component 30 when it rotates. The squeegee structure 15 can be integrally formed and connected to the inner wall of the receiving cavity 11, or it can be fixed to the inner wall of the receiving cavity 11 by snap-fit ​​or thread. The squeegee structure 15 can be a squeegee structure, a comb structure, or other structures, as long as it can scrape off the wastewater on the cleaning component 30 when it rotates. In this embodiment, the specific structure of the squeegee structure 15 is not limited.

[0313] It should be noted that the cleaning equipment 1000 is typically equipped with a wastewater tank and a clean water tank. Wastewater scraped off the cleaning unit 30 by the squeegee structure 15 flows into the wastewater tank through the wastewater outlet for collection. The clean water tank continuously supplies clean water to the cleaning unit 30 during the cleaning operation. For the location and structure of the wastewater tank and clean water tank on the cleaning equipment 1000, please refer to the relevant structural descriptions in existing cleaning equipment 1000; they will not be repeated here.

[0314] Specifically, the abutment 14 can be configured to apply forces to the cleaning member 30 in at least two directions: one is a force toward the surface to be cleaned, used to ensure effective adhesion between the cleaning member 30 and the surface to be cleaned; the other is a force toward the squeegee structure 15, used to ensure sufficient contact between the cleaning member 30 and the squeegee structure 15, so as to improve the thoroughness and stability of wastewater removal.

[0315] In this embodiment, the abutment member 14 applies a force towards the squeegee structure 15 to the cleaning member 30, ensuring that the cleaning member 30 maintains stable and close contact with the squeegee structure 15 during operation. This design not only ensures the effective removal of wastewater by the squeegee structure 15 but also suppresses bending deformation of the cleaning member 30 away from the squeegee structure 15 due to force on the side near the lateral opening 111. Therefore, it ensures the stability of the cleaning member 30 during rotational movement and maintains a stable effective cleaning area between the cleaning member 30 and the surface to be cleaned, thereby improving the overall reliability and consistency of the cleaning operation.

[0316] To achieve the simultaneous application of force from the abutment 14 towards the surface to be cleaned and towards the wiper structure 15, the abutment 14 can have various specific structures. For example, in one embodiment, the abutment 14 may have two independent parts. One part is installed on the side of the receiving cavity 11 facing the bottom opening 112 to apply a force to the cleaning member 30 towards the surface to be cleaned. The other part is installed on the inner wall of the receiving cavity 11 facing the wiper structure 15 to apply a force to the cleaning member 30 towards the wiper structure 15. In another embodiment, the abutment 14 may also be an integral structural member extending circumferentially along the receiving cavity 11, with a portion extending above the bottom opening 112 to apply a force to the cleaning member 30 towards the surface to be cleaned. Another portion extends to the side facing the wiper structure 15 to apply a force to the cleaning member 30 towards the wiper structure 15.

[0317] Optionally, please refer to Figure 44 , Figure 48 and Figure 49 In one embodiment of the present invention, the cleaning component 30 is a roller-type wiping cloth, and the abutment component 14 is an arc-shaped structure adapted to the cleaning component 30. The abutment component 14 can be integrally injection molded onto the inner wall of the receiving cavity 11, or it can be installed on the inner wall of the receiving cavity 11 by means of snap-fit, bolt fixing, etc. For details, please refer to Figures 50 to 52The abutment 14 has an approximately semi-circular ring structure, and an arc-shaped protrusion 141 is provided on the side of the abutment 14 facing the cleaning component 30 for maintaining contact with the surface of the cleaning component 30. Along the length of the receiving cavity 11, the projected outline of the abutment 14 extends at least partially to the area above the bottom opening 112 to apply a force to the cleaning component 30 toward the surface to be cleaned. At least a portion of the projected outline of the abutment 14 extends to the opposite side of the wiping structure 15, so that the abutment 14 can also apply a force to the cleaning component 30 toward the wiping structure 15.

[0318] Of course, in other embodiments, when the cleaning component 30 is a tracked rag, the abutment component 14 can also be designed to conform to the running profile of the track. By adjusting the specific shape of the abutment component 14, forces in different directions can be applied to the cleaning component 30. The specific arrangement can be referred to the aforementioned embodiments, and will not be repeated here.

[0319] In this embodiment, the abutment 14 is designed as an arc structure adapted to the roller-type cleaning cloth, and its projected outline simultaneously covers the top of the bottom opening 112 and the opposite side of the squeegee structure 15. This configuration effectively compensates for the pressure loss of the support assembly 20 at its free end by applying pressure to the cleaning component 30 toward the surface to be cleaned, ensuring the uniformity of the cleaning effect. On the other hand, it can also apply a force toward the squeegee structure 15, ensuring a tight fit between the squeegee structure 15 and the surface of the cleaning component 30, improving the efficiency of wastewater removal. In addition, the arc structure can also provide a uniform and stable abutment force in the circumferential direction of the cleaning component 30, helping to suppress abnormal deformation and jumping of the cleaning component 30 during rotation, thus enhancing the smoothness and reliability of the rotation of the cleaning component 30.

[0320] Without considering whether the downward pressure of the cleaning member 30 is uniform on the side near the lateral opening 111, if only the lateral pressure generated by the wiping structure 15 on the cleaning member 30 on that side is optimized, optionally, in one embodiment of the invention, the cleaning device 100 further includes a wiping structure 15, which at least partially extends into the receiving cavity 11 and contacts the cleaning member 30 to scrape off wastewater from the cleaning member 30. The housing 10 is provided with an abutment member 14 on the side near the lateral opening 111, which can apply a force to the cleaning member 30 toward the side of the wiping structure 15.

[0321] Specifically, the abutment 14 can be configured to apply a force to the cleaning member 30 only towards the side facing the wiping structure 15. For example, the abutment 14 can be a protrusion structure disposed on the inner wall of the receiving cavity 11 and facing the side facing the wiping structure 15. This protrusion structure abuts against the cleaning member 30 to apply a unidirectional force to the cleaning member 30 towards the wiping structure 15. Of course, in other embodiments, the abutment 14 can also adopt an arc structure as shown in the previous embodiments. This type of abutment 14 can simultaneously apply a force towards the wiping structure 15 and a force towards the surface to be cleaned to the cleaning member 30, thereby optimizing lateral pressure while ensuring the uniformity of the downward pressure of the cleaning member 30.

[0322] In this embodiment, by providing the abutment member 14 and applying a force towards the wiping structure 15 to the cleaning member 30, it is effectively ensured that the cleaning member 30 maintains a tight and stable contact with the wiping structure 15 in the wiping area. This improves the efficiency and thoroughness of wastewater removal and alleviates problems such as incomplete wiping and wastewater residue caused by the cleaning member 30 not fitting tightly.

[0323] Please see Figure 1 , Figure 53 and Figure 54 In one embodiment of the present invention, the cleaning device 1000 includes a body 200 and a cleaning device 100 as described in any of the above embodiments, the cleaning device 100 being mounted on the body 200. The specific mounting method of the cleaning device 100 on the body 200 can be referred to the relevant descriptions in the foregoing embodiments. Of course, in other embodiments, two or more cleaning devices 100 may be provided. For example, in one embodiment, two cleaning devices 100 are provided, and the two cleaning devices 100 are respectively disposed in the width direction of the body 200 (e.g., ...). Figure 53 (As shown on the Y-axis). In actual design, the number of cleaning devices 100 can be selected according to the specific cleaning scenario requirements.

[0324] With the cleaning device 100 installed on one side of the body 200 in the width direction, various relative positional structures can be formed between the outer edge of its housing 10 and the outer edge of the body 200. For example, the outer edge of the housing 10 can be flush with the outer edge of the body 200 in the width direction; the outer edge of the housing 10 can extend beyond the outer edge of the body 200; or the outer edge of the housing 10 can be located inside the outer edge of the body 200. It should be noted that in this embodiment, the flush alignment of the outer edge of the housing 10 with the outer edge of the body 200 in the width direction should be understood as an approximate alignment achieved within reasonable engineering installation and manufacturing tolerances. Specifically, this alignment relationship allows for a certain range of error, which is determined by factors such as the manufacturing precision of the components, assembly clearances, and material properties.

[0325] In this embodiment, since the cleaning device 100 described in the previous embodiment is installed on the body 200, when the cleaning device 1000 moves along the wall, baseboard, or furniture edge, the exposed end (i.e., the first end 31) of the cleaning component 30 can be as close as possible to these edge areas, thereby significantly reducing cleaning blind spots caused by structural limitations. Therefore, the cleaning effect of edge areas can be improved, especially in areas where traditional cleaning blind spots are more obvious, such as the lower part of the wall baseboard and the perimeter of furniture legs, enabling more thorough cleaning and thus improving overall cleaning efficiency and user experience.

[0326] While meeting the basic cleaning requirements of the cleaning equipment 1000, the installation structure of the cleaning device 100 on the body 200 can be implemented in various ways. For example, the cleaning device 100 can be directly and fixedly installed on the bottom of the body 200, in which case the position of the cleaning component 30 relative to the body 200 remains fixed. In another embodiment, the cleaning device 100 can be movably installed on the bottom of the body 200 through an external swing assembly, allowing the cleaning component 30 to switch between multiple working positions relative to the body 200.

[0327] Optionally, in one embodiment of the present invention, the cleaning device 1000 further includes an outward swing assembly (not shown in the figure). The cleaning device 100 is connected to the body 200 via the outward swing assembly. The outward swing assembly is retractably mounted on the body 200 and can drive the cleaning device 100 to a retracted position (e.g., Figure 53 (as shown) and the outer swing position (as shown) Figure 1 and Figure 54 The cleaning device 100 operates between the shown positions. When the cleaning device 100 is in the outward position, the cleaning device 100 can extend to the outside of the body 200 along the width direction, that is, the outer edge of the housing 10 of the cleaning device 100 can extend to the outside of the body 200 along the width direction. In another embodiment, when the cleaning device 100 is in the outward position, the cleaning device 100 can be flush with the edge of the body 200 along the width direction, that is, the edge of the housing 10 of the cleaning device 100 can be flush with the edge of the body 200 along the width direction.

[0328] It should be noted that, as Figure 53 As shown, when the cleaning device 100 is in the retracted position, the cleaning device 100 is retracted into the internal space of the body 200, that is, the edge of the housing 10 of the cleaning device 100 is located inside the edge of the body 200.

[0329] The specific structure of the swing-out component is not limited. For example, the swing-out component can be a horizontal telescopic mechanism (such as a ball screw mechanism or a rack and pinion mechanism). The moving end and the fixed end of the horizontal telescopic mechanism are respectively installed on the housing 10 and the body 200 of the cleaning device 100. By the horizontal movement of the moving end relative to the fixed end, the cleaning device 100 moves between the retracted position and the swing-out position relative to the body 200. In another embodiment, the swing-out component can also be a rotary mechanism (such as a worm gear or gear transmission assembly). The rotation output end of the rotary mechanism is connected to the housing 100 of the cleaning device 100. The operation of the rotary mechanism can drive the cleaning device 100 to rotate within a certain angle range, thereby realizing the operation of the cleaning device 100 between the retracted position and the swing-out position. The specific structure of the swing-out component in this embodiment can be referred to the relevant structure description in existing cleaning equipment, and will not be repeated here.

[0330] In this embodiment, the cleaning device 100 works in conjunction with the outward swing component. The outward swing component drives the cleaning device 100 to swing outward, allowing the cleaning component 30 to actively conform to the edge of the area to be cleaned. When the cleaning device 1000 travels or turns along walls, furniture edges, or baseboards, this structure allows the exposed end (i.e., the first end 31) of the cleaning component 30 to directly and fully conform to the wall, baseboard, or furniture edge, significantly reducing cleaning blind spots caused by structural limitations. This design significantly expands the effective cleaning range of the device, improves the cleaning effect in edge and corner areas, especially in areas with obvious traditional cleaning blind spots such as the lower part of walls and baseboards and around furniture legs, enabling more thorough cleaning and thus improving overall cleaning efficiency and user experience.

[0331] Please see Figure 1 , Figure 53 and Figure 54 The present invention also provides a cleaning device 1000, which is a self-moving cleaning device, including a body 200 and at least one cleaning device 100 as described in any of the above embodiments, wherein the cleaning device 100 is installed on the body 200. The self-moving cleaning device in this embodiment can be a mopping robot, or a sweeping and mopping robot, etc. The specific installation structure of the cleaning device 100 on the body 200 can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0332] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
