Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning device. Background Technology

[0002] Most robotic vacuum cleaners nowadays have a mopping function, which is achieved by setting a mopping module on the bottom of the robot.

[0003] Most robotic vacuum cleaners currently use a disc-shaped mop assembly for their mopping module. The mop is embedded in the chassis, with the mop bracket fixed to the bottom of the main body (usually ≤5cm from the edge of the device). The mop is moved by the movement of the whole machine to wipe the floor.

[0004] However, many areas in the home environment have height restrictions (such as 8-15cm gaps under beds / sofas, and 3-6cm recesses in cabinet baseboards), while the main body of the robot is generally ≥9cm high. When the robot body cannot enter, its cleaning cloth component completely loses its cleaning ability due to the physical obstruction effect, resulting in poor cleaning performance. Utility Model Content

[0005] This application provides a cleaning device to solve the problem in the above-mentioned related technologies where the wiping cloth component loses its cleaning ability due to physical obstruction, resulting in poor cleaning effect.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a cleaning device, including:

[0008] Equipment body;

[0009] The wiping cloth assembly is detachably connected to the main body of the equipment. The wiping cloth assembly includes a walking mechanism, which is used to drive the wiping cloth assembly to be fixedly connected to or detached from the main body of the equipment. The walking mechanism is also used to drive the wiping cloth assembly to change its position relative to the main body of the equipment on the surface to be cleaned.

[0010] The connecting component includes a first end and a second end. The first end is connected to the main body of the device, and the second end is connected to the wiping assembly. The distance between the first end and the second end is variable. The connecting component is used to restrict the movement of the wiping assembly within a preset area. The preset area is larger than the cleaning area covered when the wiping assembly is fixedly connected to the main body of the device.

[0011] By incorporating a walking mechanism, the cleaning cloth assembly can move relative to the main body of the device. When fixedly connected to the main body, it functions as a regular cleaning cloth assembly that moves with the main body. When detached from the main body, it can move to the outside of the main body for cleaning, thereby expanding the cleaning equipment's coverage area. For example, the walking mechanism can propel the cleaning cloth assembly into lower areas (under the bed) for cleaning without requiring the entire main body of the device to enter these areas. Since the cleaning cloth assembly is much thinner than the main body, this allows the cleaning equipment to clean areas that the main body cannot access, thus expanding the cleaning range.

[0012] By connecting the cleaning cloth assembly to the main body of the device via a connecting component, a physical connection between the two is established. Since the length of the connecting component is variable, the cleaning cloth assembly can move within a certain range. Compared to related technologies that require a separate submodule for cleaning low-lying areas, this solution eliminates the need for additional installation space (the cleaning cloth assembly is also required during normal cleaning), effectively saving costs and installation space. Furthermore, the physical connection allows the main body to control the cleaning cloth assembly even when it is detached from the main body, ensuring stable control signals. Since the distance between the cleaning cloth assembly and the main body is controlled within a specific range by the connecting component, the cleaning cloth assembly can share the main body's positioning, map, and sensor information, effectively saving control resources.

[0013] In one possible implementation, the walking mechanism includes:

[0014] Mounting base, used for detachable connection to the main body of the equipment;

[0015] A traveling wheel assembly is movably connected to a fixed base. The traveling wheel assembly includes a traveling wheel that can rotate about the central axis of the traveling wheel.

[0016] The first drive assembly is connected to the drive of the walking wheel and is used to drive the walking wheel to rotate around the central axis of the walking wheel.

[0017] By incorporating a fixed base that is detachably connected to the main body of the equipment, the walking mechanism can be easily installed or disassembled. This modular design facilitates maintenance and replacement of the walking mechanism components, extending the service life of the cleaning equipment. The walking wheel assembly is movably connected to the fixed base, and the wheels can rotate around their central axis, allowing the mop assembly to move flexibly in different directions, enabling the cleaning equipment to adapt to various complex cleaning environments. The first drive assembly is connected to the walking wheel transmission, effectively driving the wheels to rotate, thereby propelling the mop assembly. Due to the design of the walking wheel assembly, the equipment can move on various floor materials, including hard floors and carpets, demonstrating strong adaptability and expanding the equipment's application scenarios.

[0018] In one possible implementation, the walking wheel assembly also includes a walking bracket, which is rotatably connected to the walking wheel;

[0019] The traveling support and the fixed base are movably connected in the height direction of the main body of the equipment, and are rotatably connected in the circumferential direction of the fixed base;

[0020] The walking mechanism also includes a second drive component;

[0021] The second drive assembly is connected to the traveling bracket in a transmission manner. The second drive assembly is used to drive the traveling bracket to rotate the traveling wheels around the circumference of the fixed base.

[0022] The walking bracket is movably connected to the fixed base along the height of the main body of the equipment. The walking wheel assembly can float vertically, allowing the mop assembly to adjust its height when encountering obstacles. This provides cushioning when the cleaning equipment encounters obstacles, reducing physical wear and impact, improving the equipment's durability, and better adapting to different terrains and cleaning needs. The walking bracket is circumferentially connected to the fixed base and driven by a second drive assembly, allowing the walking wheels to rotate 360 ​​degrees around the main body of the equipment. This design provides omnidirectional mobility, enabling the mop assembly to flexibly turn and move in confined or complex spaces.

[0023] In one possible implementation, the traveling support includes a support body, a first connecting member, a second connecting member, and an elastic member. The support body is rotatably connected to the traveling wheels.

[0024] One end of the first connector is fixedly connected to the bracket body, and the other end passes through the second connector and is movably connected to the second connector.

[0025] The second connector is rotatably connected to the fixed base in the circumferential direction of the fixed base;

[0026] The elastic element is sleeved on the outside of the first connector, and in the height direction of the equipment body, the elastic element is located between the support body and the second connector. The elastic element is retractable in the height direction of the equipment body.

[0027] By incorporating an elastic element, cushioning is provided between the second connector and the support body. When the cleaning equipment moves on uneven ground or encounters obstacles, the elastic element absorbs impact, reducing physical damage to the equipment and improving its durability. The elastic element is extendable and retractable in the height direction of the equipment body, allowing the walking support to automatically adjust its height to adapt to different terrain changes. This design enables the equipment to maintain stable cleaning performance under various ground conditions. The combination of the first and second connectors makes the connection between the support body and the fixed base more flexible.

[0028] In one possible implementation, the first connector is a rod-shaped structure, and the second connector is a circular plate-shaped structure.

[0029] By designing the first connector as a rod-like structure, its structure is simplified, materials are saved, and costs are reduced. Designing the second connector as a circular plate-like structure provides a stable support surface, ensuring the stability of the walking bracket. The circular plate-like structure of the second connector allows for smooth rotation around the fixed base, enabling the wheels to move freely around the equipment, improving its flexibility and maneuverability. Furthermore, the circular plate-like structure evenly distributes forces from the first connector and the elastic element, reducing localized stress concentration and lowering the risk of material fatigue and damage. Because the first connector is rod-like, the elastic element can be more effectively fitted onto its outer side, achieving better telescopic functionality. This enhances the automatic height adjustment capability of the cloth assembly.

[0030] In one possible implementation, the first drive component includes a first motor and a first transmission component; wherein,

[0031] The first motor is driven and connected to the first transmission assembly, which is driven and connected to the walking wheel. The first motor is used to drive the walking wheel to rotate around the central axis of the walking wheel through the first transmission assembly.

[0032] This configuration, where the first motor drives the traveling wheels to rotate via the first transmission assembly, enables highly efficient energy transfer. This ensures that the power of the first motor is effectively transmitted to the traveling wheels, guaranteeing the smooth and efficient operation of the cleaning equipment. The first motor can precisely control the rotational speed and direction of the traveling wheels. This precision allows the mop assembly to adjust its speed and plan its path according to the needs of the cleaning task, improving cleaning effectiveness.

[0033] In one possible implementation, the first transmission assembly includes a gear set, a worm gear, and a first gear; wherein,

[0034] The output shaft of the first motor is connected to the gear set, the gear set is connected to the worm gear, the worm gear is connected to the first gear, and the first gear is connected to the rotating shaft of the traveling wheel.

[0035] The combination of gears and a worm gear effectively transmits the motor's output torque to the wheels. This ensures efficient power transmission and improves the operating efficiency of the cleaning equipment. Worm gear drives offer significant speed reduction and torque amplification capabilities, which is particularly important for cleaning equipment requiring substantial driving force. Through this transmission method, the wheels can achieve greater torque output to cope with different terrains and loads. The worm gear drive also features a self-locking characteristic, meaning the wheels will not rotate in the opposite direction when no external force is applied, helping to improve the stability of the mop assembly on slopes or uneven surfaces and preventing accidental slippage.

[0036] In one possible implementation, the second drive component may include a second motor and a second transmission component; wherein,

[0037] The second motor is driven by the second transmission assembly, which is driven by the walking bracket. The second motor is used to drive the walking bracket to rotate circumferentially along the fixed base via the second transmission assembly.

[0038] A second motor drives the walking bracket to rotate circumferentially around the fixed base, enabling the walking mechanism to rotate 360 ​​degrees. In other words, the walking mechanism can turn freely on the surface to be cleaned, making it easier to change its path and improving obstacle avoidance performance. This allows the walking mechanism to maneuver the mop assembly flexibly in confined or complex spaces, allowing it to cover a wider area and improving cleaning efficiency and coverage. The combination of the second motor and the second transmission component makes precise control of the walking bracket's rotation direction and speed possible. This precision helps optimize the cleaning path, reducing repetitive cleaning and missed areas.

[0039] In one possible implementation, the second transmission assembly includes a second gear and a third gear; wherein,

[0040] The second motor is fixedly connected to the walking frame, the output shaft of the second motor is connected to the second gear transmission, and the second gear is movably connected to the walking frame.

[0041] The third gear is fixedly connected to the fixed base, and the second gear is meshed with the third gear.

[0042] The second motor drives the second gear to rotate circumferentially along the third gear, thereby causing the traveling bracket to rotate circumferentially along the fixed base.

[0043] Through the meshing connection of the second and third gears, the output of the second motor can be effectively transmitted to the traveling bracket, achieving efficient power transmission and ensuring the smooth rotation of the traveling bracket. The arrangement of the first and second gears allows for precise control of the traveling bracket's rotation. By adjusting the gear ratio, the traveling mechanism can achieve different rotational speeds and directions to meet the needs of various cleaning tasks. The third gear, fixedly connected to the base, provides a stable reference point, helping to improve the stability of the traveling bracket during rotation and reducing vibration and deviation. Gear transmission systems can often be designed to be very compact, saving space. This compactness helps reduce the overall size of the equipment, facilitating operation in confined spaces. In some designs, gear transmission systems can have a self-locking characteristic, meaning the traveling bracket will not rotate in the opposite direction when no external force is applied. This feature helps improve the stability of the equipment and prevents accidental slippage.

[0044] In one possible implementation, the mounting base includes a top plate and a side wall, the side wall surrounding the top plate, and the top plate and side wall being fixedly connected; wherein...

[0045] The traveling bracket is rotatably connected to the side wall along the circumference of the fixed seat, and the third gear is fixedly connected to the top plate;

[0046] The top plate is used for detachable connection with the main body of the equipment.

[0047] This configuration, with the top plate and sidewalls fixedly connected, forms a robust frame structure, providing excellent mechanical stability and effectively supporting the weight and motion loads of the traveling bracket and other components. The traveling bracket and sidewalls rotate circumferentially along the fixed base, providing a stable rotation path and ensuring the smoothness and precision of the traveling bracket during rotation. The sidewalls surround the top plate, forming a compact whole. This design saves space, enabling the traveling mechanism to achieve complex motion functions within a limited space. The top plate is used for detachable connection to the main body of the equipment, making the installation and removal of the fixed base and other components more convenient. This design simplifies the equipment maintenance and parts replacement process.

[0048] In one possible implementation, the cleaning equipment also includes a fixing element; wherein,

[0049] The fastener is located on the side of the equipment body facing the surface to be cleaned;

[0050] The cloth assembly is used for detachable connection with the fastener.

[0051] This design allows for quick disassembly and replacement of the cloth assembly, making it convenient for users to change the cloth when it becomes dirty or damaged. This simplifies daily maintenance of the cleaning equipment and extends the lifespan of the cloth assembly. By changing to different types of cloth assemblies, the cleaning equipment can adapt to various cleaning tasks and surface materials. For example, different types of cloths can be used to treat hard floors, carpets, or sensitive surfaces. The detachable cloth assembly design allows users to select the most suitable cloth type as needed, thereby improving cleaning efficiency and effectiveness. Users can replace the cloth assembly individually without replacing the entire device. This design reduces long-term operating costs, making the equipment more economical.

[0052] In one possible implementation, the fastener has a connecting portion on the side facing the cloth assembly;

[0053] The cloth assembly includes a locking part that mates with the connecting part;

[0054] When the wiping cloth assembly is fixedly connected to the fastener, the connecting part and the locking part engage.

[0055] When the cloth assembly is disengaged from the fastener, the connecting part separates from the locking part.

[0056] This design, with its interlocking mechanism, allows users to quickly install and remove the cloth assembly. The interlocking connection provides a secure fixation, ensuring the cloth assembly won't accidentally detach during operation, improving the safety and reliability of the cleaning process. Installing and removing the cloth assembly can be done without tools, simplifying the operation and enhancing the user experience. The interlocking connection design typically includes anti-misoperation features to prevent the cloth assembly from detaching under improper circumstances, ensuring the safe operation of the cleaning equipment.

[0057] In one possible implementation, the connecting part is a column structure extending toward the cloth assembly;

[0058] The locking part is a groove structure, and the groove structure is open at one end of the fixed base in the circumferential direction. The column structure enters the groove structure from the opening and engages with the groove structure.

[0059] The installation process is intuitive and simple by designing the column structure to be accessible through the opening in the recessed structure. Simply screw the column structure into the recessed structure through the opening, and the column and recessed structure will engage, allowing for quick installation and preventing the cloth assembly from accidentally detaching. The engagement between the column and recessed structure provides a secure connection, ensuring the cloth assembly will not accidentally fall off during use. This stability improves the reliability and safety of the cleaning equipment. Because the recessed structure opens only at one end, the column structure must be inserted from a specific direction; this design reduces the possibility of misoperation and ensures correct installation of the cloth assembly.

[0060] In one possible implementation, the locking part is fixedly connected to the traveling wheel assembly and movably connected to the fixed seat;

[0061] The mounting base is provided with mounting holes for the connecting parts to pass through.

[0062] This design allows for a certain degree of free movement in the movable connection between the locking part and the fixed base. When the connecting part is inserted into the mounting hole, the locking part can be engaged or disengaged by rotating the traveling wheel assembly. The entire process can be completed automatically by the traveling mechanism without manual operation. This allows the cleaning equipment's cloth assembly to automatically switch between normal and extended modes according to cleaning needs, improving the automation of the cleaning equipment and enhancing the user experience.

[0063] In one possible implementation, the cloth assembly includes a cleaning component and a third drive component; wherein,

[0064] The third drive assembly is located on the outside of the walking mechanism and is fixedly connected to the fixed base;

[0065] The cleaning component has an opening in the middle, which allows the traveling mechanism to contact the surface to be cleaned.

[0066] The third drive assembly is connected to the cleaning component via a transmission, and is used to drive the cleaning component to rotate and perform cleaning operations.

[0067] This configuration allows the third drive assembly to be dedicated to rotating the cleaning component, making the cleaning function independent of the movement of the walking mechanism. This independence allows for more precise and efficient cleaning operations, improving cleaning results. The rotational movement of the cleaning component can cover a larger cleaning area, reducing missed areas and improving overall cleaning efficiency. By rotating the cleaning component, different cleaning paths and modes can be achieved to adapt to different floor materials and cleaning needs. The open design in the middle of the cleaning component allows the walking mechanism to directly contact the surface to be cleaned, reducing friction and wear between the cleaning component and the ground, and extending the service life of the cleaning component. The design of the third drive assembly can adapt to different types and shapes of cleaning components, enabling the equipment to flexibly handle various cleaning tasks. The design of the mounting base ensures that the third drive assembly is securely installed, avoiding the risk of loosening or falling off during operation.

[0068] In one possible implementation, the connecting component includes a plurality of connectors disposed along the extending direction of the connecting component; wherein...

[0069] Two adjacent connectors are rotatably connected, with the axis of rotation of the connectors parallel to the height direction of the equipment body, and the relative positions of the two adjacent connectors in the height direction of the equipment body are fixed.

[0070] The first end is fixedly connected to the main body of the equipment, and the second end is fixedly connected to the wiping cloth assembly;

[0071] The connecting component can be wrapped around the outer periphery of the cloth component.

[0072] This design, with adjacent connectors rotating in the vertical direction, allows them to swing left and right, giving the connecting assembly a degree of flexibility. This enables the cloth assembly to move flexibly and can be stored by wrapping, reducing space occupation. By adjusting the number and length of the connectors, the device can accommodate cloth assemblies of different sizes and shapes, enhancing its versatility.

[0073] In one possible implementation, the connecting component includes a plurality of connectors disposed along the extending direction of the connecting component; wherein...

[0074] Two adjacent connectors can be extended and retracted in the extension direction of the connecting assembly;

[0075] The first end is rotatably connected to the main body of the equipment in the height direction of the main body, and the second end is fixedly connected to the wiping cloth assembly.

[0076] This retractable connection allows the length of the connecting assembly to be adjusted to adapt to different cleaning tasks and environments. This flexibility allows the device to be optimized for cleaning surfaces of varying heights and shapes. The telescopic function makes the mop assembly more easily accessible to hard-to-reach areas, such as low-ceilinged spaces or narrow crevices, improving cleaning coverage and effectiveness. When not in use, the connecting assembly can retract to its minimum length, reducing storage space requirements for the mop assembly and facilitating transportation and storage. Despite its telescopic nature, the design of the connecting assembly ensures the mop assembly remains stable during cleaning, reducing performance degradation due to vibration or imbalance. The telescopic and swivel connection design ensures the mop assembly will not accidentally detach during use, providing a safe operating environment. Attached Figure Description

[0103] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0104] To clean indoor environments, people commonly use robotic vacuum cleaners, vacuum cleaners, and floor scrubbers. Among these, robotic vacuum cleaners are widely popular because they require no human intervention throughout the cleaning process. Robotic vacuum cleaners consist of a roller brush and a mop assembly. The roller brush at the bottom performs initial cleaning, followed by a secondary cleaning with the mop assembly at the rear, thus improving the cleaning effect.

[0105] Robotic vacuum cleaners typically have a certain height, making it impossible for them to access relatively low areas, such as under beds. This results in many areas remaining uncleaned, forcing users to clean manually, which leads to a poor user experience.

[0106] To address these issues, related technologies often incorporate a sub-module that works in conjunction with the robotic vacuum cleaner. This sub-module can be detached from the vacuum cleaner and then assists in cleaning specific areas. However, this separate sub-module requires additional installation space, as well as a dedicated positioning and control system. This results in a complex and bulky main unit structure for the robotic vacuum cleaner, hindering cost reduction.

[0107] To address the aforementioned technical problems, this application provides a cleaning device that connects a cloth assembly to the main body of the device via a connecting component. This allows for a physical connection between the cloth assembly and the main body. Since the length of the connecting component is variable, the cloth assembly can move within a certain range. Compared to related technologies that require a separate submodule for cleaning low-lying areas, this application's solution eliminates the need for additional installation space (as a cloth assembly is also required during normal cleaning), effectively saving costs and installation space.

[0108] The cleaning equipment provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0109] Figure 1 This is a schematic diagram of the structure of a cleaning device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a cleaning device's cloth assembly and connecting assembly provided in an embodiment of this application.

[0110] It should be noted that, for ease of description, in this embodiment, the height direction of the cleaning equipment is taken as the z-direction.

[0111] This application provides a cleaning device, such as... Figure 1 As shown, the cleaning device 100 may include a device body 10, a cloth assembly 20, and a connecting assembly 30. The cloth assembly 20 is detachably connected to the device body 10, and the cloth assembly 20 may include a walking mechanism 21 and a cleaning component 22 (see...). Figure 4 As shown), the cleaning component 22 is located on the side of the cloth assembly 20 facing the surface to be cleaned.

[0112] For example, the cleaning component 22 is arranged around the walking mechanism 21, and the cleaning component 22 has an opening in the middle for the walking mechanism 21 to contact the surface to be cleaned. The cleaning component 22 can be rotated to enable the cloth assembly 20 to perform cleaning operations.

[0113] The walking mechanism 21 is used to drive the wiping cloth assembly 20 to be fixedly connected to or disconnected from the main body of the equipment 10. The walking mechanism 21 is also used to drive the wiping cloth assembly 20 to change its position relative to the main body of the equipment 10 on the surface to be cleaned.

[0114] By incorporating the walking mechanism 21, the wiping assembly 20 can move relative to the main body 10 of the device. When fixedly connected to the main body 10, it functions as a regular wiping assembly 20 that moves with the main body 10. When disconnected from the main body 10, it can move to the outside of the main body 10 to perform cleaning operations, thereby expanding the coverage area of ​​the cleaning device 100. For example, the walking mechanism 21 can drive the wiping assembly 20 into lower areas (under the bed) for cleaning without requiring the entire main body 10 to enter these areas. Since the wiping assembly 20 is much thinner than the main body 10, this allows the cleaning device 100 to clean more areas that the main body 10 cannot access, thus expanding the cleaning range.

[0115] For example, the connecting component 30 may include a first end 31 and a second end 32. The first end 31 is connected to the device body 10, and the second end 32 is connected to the wiping component 20. The distance between the first end 31 and the second end 32 is variable. The connecting component 30 is used to restrict the movement of the wiping component 20 within a preset area. The preset area is larger than the cleaning area covered when the wiping component 20 is fixedly connected to the device body 10.

[0116] The wiping assembly 20 is connected to the device body 10 via the connecting component 30, enabling a physical connection between them. Since the length of the connecting component 30 is variable, the wiping assembly 20 can move within a certain range. Compared to related technologies that use a separate submodule for cleaning low-lying areas, this solution eliminates the need for additional installation space (the wiping assembly 20 is also required during normal cleaning), effectively saving costs and installation space. Furthermore, the physical connection allows the device body 10 to control the wiping assembly 20 even when it is detached from the device body 10, ensuring stable control signals. Since the distance between the wiping assembly 20 and the device body 10 is controlled within a specific range by the connecting component 30, the wiping assembly 20 can share the device body 10's positioning, map, and sensor information, effectively saving control resources.

[0117] In one possible implementation, such as Figure 2 As shown, the connecting assembly 30 may include multiple connectors 33 arranged along the extending direction of the connecting assembly 30. Adjacent connectors 33 are rotatably connected, with the axis of rotation of the connector 33 parallel to the height direction (z-direction) of the device body 10, and the relative positions of adjacent connectors 33 in the height direction of the device body 10 are fixed. A first end 31 is fixedly connected to the device body 10, and a second end 32 is fixedly connected to the cloth assembly 20. The connecting assembly 30 can be wound around the outer periphery of the cloth assembly 20.

[0118] For example, the connecting component 30 can be a chain structure. Two adjacent connecting parts 33 are rotatably connected, and the relative positions of the two adjacent connecting parts 33 in the z-direction are fixed. This allows the connecting component 30 to maintain a certain pressure on the wiping cloth assembly 20 when in the open state, ensuring that the cleaning part 22 of the wiping cloth assembly 20 can fit tightly against the ground and apply a certain pressure to the ground to ensure the cleaning effect of the cleaning part 22.

[0119] Because adjacent connectors 33 are rotatably connected in the height direction, the two adjacent connectors 33 can swing left and right, thus giving the connecting assembly 30 a certain degree of flexibility. This allows for flexible movement of the cloth assembly 20 and enables it to be stored by wrapping, reducing its space occupation. By adjusting the number and length of the connectors 33, the device can adapt to cloth assemblies 20 of different sizes and shapes, enhancing its versatility. During use, the walking mechanism 21 can be controlled to move, allowing the connecting assembly 30 to wrap around the outer periphery of the cloth assembly 20 or to open.

[0120] Of course, in other embodiments, the connecting component 30 may also be other structures.

[0121] like Figure 3 As shown, the connecting assembly 30 may include a plurality of connectors 33 arranged along the extending direction of the connecting assembly 30. Adjacent connectors 33 are telescopically connected in the extending direction of the connecting assembly 30. A first end 31 is rotatably connected to the device body 10 in the height direction of the device body 10, and a second end 32 is fixedly connected to the wiping cloth assembly 20.

[0122] For example, the relative positions of two adjacent connectors 33 in the z-direction remain unchanged. This allows the connector 30 to maintain a certain pressure on the wiping cloth assembly 20 when it is in the open state, ensuring that the cleaning component 22 of the wiping cloth assembly 20 can fit tightly against the ground and apply a certain pressure to the ground to ensure the cleaning effect of the cleaning component 22.

[0123] Furthermore, the retractable connector 33 allows the connecting assembly 30 to be adjusted in length to adapt to different cleaning tasks and environments. In this embodiment, the length of each connector 33 is not further limited. During use, the connecting assembly 30 can be gradually opened or retracted by controlling the movement of the walking mechanism 21. This flexibility allows the device to be optimized for cleaning surfaces of different heights and shapes. Through its telescopic function, the mop assembly 20 can more easily reach hard-to-reach areas, such as low spaces or narrow crevices, improving cleaning coverage and effectiveness. When not in use, the connecting assembly 30 can be retracted to its minimum length, reducing the storage space requirement of the mop assembly 20 and facilitating transportation and storage. Despite its telescopic nature, the design of the connecting assembly 30 ensures that the mop assembly 20 remains stable during cleaning, reducing performance degradation due to vibration or imbalance. The telescopic and rotating connection design ensures that the mop assembly 20 will not accidentally detach during use, providing a safe operating environment.

[0124] It should be noted that in some other embodiments, the connecting component 30 can be configured as other structures, such as ropes. In this embodiment, the specific structure of the connecting component 30 is not further limited.

[0125] The specific structure of the wiping cloth assembly 20 will be described below with reference to the accompanying drawings.

[0126] In one possible implementation, such as Figure 4 and Figure 5 As shown, the walking mechanism 21 may include a fixed base 211, a walking wheel assembly 212, and a first drive assembly 213. The fixed base 211 is used for detachable connection with the main body 10 of the equipment.

[0127] Correspondingly, a connector 33 that mates with the fixing base 211 is provided on the main body 10 of the device. The fixing member 40 is located on the side of the main body 10 facing the surface to be cleaned. The cloth assembly 20 is detachably connected to the fixing member 40. Specifically, the fixing base 211 of the traveling mechanism 21 is detachably connected to the fixing member 40.

[0128] The cloth assembly 20 can be quickly disassembled and replaced, allowing users to easily replace the cloth when it becomes dirty or damaged, simplifying daily maintenance of the cleaning device 100 and extending its lifespan. By changing to different types of cloth assemblies 20, the cleaning device 100 can adapt to different cleaning tasks and surface materials. For example, different types of cloths can be used to treat hard floors, carpets, or sensitive surfaces. The detachable cloth assembly 20 design allows users to select the most suitable cloth type as needed, thereby improving cleaning efficiency and effectiveness. Users can replace the cloth assembly 20 individually without replacing the entire device. This design reduces long-term operating costs, making the device more economical.

[0129] See also Figure 4 and Figure 5 As shown, the traveling wheel assembly 212 is movably connected to the fixed base 211. The traveling wheel assembly 212 may include a traveling wheel 2121, which is rotatable around its central axis. The central axis of the traveling wheel 2121 is parallel to the surface to be cleaned. That is, when the traveling wheel 2121 rotates, it can roll on the surface to be cleaned, thereby moving the cloth assembly 20 on the surface. The first drive assembly 213 is drively connected to the traveling wheel 2121, and the first drive assembly 213 is used to drive the traveling wheel 2121 to rotate around its central axis.

[0130] By setting a fixed base 211 and detachably connecting it to the main body 10, the walking mechanism 21 can be easily installed or disassembled. This modular design facilitates maintenance and replacement of the components of the walking mechanism 21, extending the service life of the cleaning equipment 100. The walking wheel assembly 212 is movably connected to the fixed base 211, and the walking wheel 2121 can rotate around its central axis, allowing the mop assembly 20 to move flexibly in different directions, enabling the cleaning equipment 100 to adapt to various complex cleaning environments. The first drive assembly 213 is connected to the walking wheel 2121, effectively driving the walking wheel 2121 to rotate, thereby propelling the mop assembly 20. Due to the design of the walking wheel assembly 212, the equipment can move on various floor materials, including hard floors and carpets, demonstrating strong adaptability and expanding the application scenarios of the cleaning equipment 100.

[0131] See also Figure 4 As shown, the traveling wheel assembly 212 may further include a traveling bracket 2122, which is rotatably connected to the traveling wheel 2121. A connecting shaft 2123 and a bearing 2124 are provided between the traveling wheel 2121 and the traveling bracket 2122, and the hub of the traveling wheel 2121 and the traveling bracket 2122 are rotatably connected through the connecting shaft 2123 and the bearing 2124.

[0132] For example, the walking bracket 2122 may include a bracket body 2122a. The bracket body 2122a may include at least a support plate 2122b that is spaced apart from the walking wheel 2121 along its axial direction. The support plate 2122b has a first mounting hole 2122c for mounting the connecting shaft 2123. A bearing 2124 may be disposed in the first mounting hole 2122c, and the outer ring of the bearing 2124 is fixedly connected to the first mounting hole 2122c. The inner ring of the bearing 2124 is fixedly connected to the connecting shaft 2123, and the inner and outer rings of the bearing 2124 are rotatably connected. Correspondingly, the hub of the walking wheel 2121 has a second mounting hole 2121a for mounting the connecting shaft 2123. The connecting shaft 2123 passes through the second mounting hole 2121a and is fixedly connected to the hub of the walking wheel 2121. When the connecting shaft 2123 rotates, it can drive the walking wheel 2121 to rotate. This allows the traveling wheel 2121 to rotate relative to the traveling bracket 2122, and when the traveling wheel 2121 rotates, it can drive the traveling bracket 2122 to move together on the surface to be cleaned.

[0133] See Figure 6 As shown, the first drive assembly 213 may include a first motor 2131 and a first transmission assembly 2132. The first motor 2131 is drivenly connected to the first transmission assembly 2132, and the first transmission assembly 2132 is drivenly connected to the walking wheel 2121. The first motor 2131 is used to drive the walking wheel 2121 to rotate around the central axis of the walking wheel 2121 through the first transmission assembly 2132.

[0134] For example, the first drive assembly 213 can be mounted on the walking bracket 2122. For instance, the first drive assembly 213 is fixed to the support plate 2122b of the bracket body 2122a. This allows the first drive assembly 213 to move together with the walking wheels 2121, reducing assembly difficulty.

[0135] With this configuration, the first motor 2131 drives the walking wheel 2121 to rotate via the first transmission assembly 2132, achieving efficient energy transfer. This ensures that the power of the first motor 2131 is effectively transmitted to the walking wheel 2121, guaranteeing the smooth and efficient operation of the cleaning equipment 100. The first motor 2131 can precisely control the rotational speed and direction of the walking wheel 2121. This precision allows the cloth assembly 20 to adjust its speed and plan its path according to the needs of the cleaning task, improving the cleaning effect.

[0136] In one possible implementation, the first transmission assembly 2132 may include a gear set 2132a, a worm gear 2132b, and a first gear 2132c. The output shaft of the first motor 2131 is connected to the gear set 2132a, the worm gear 2132b of the gear set 2132a is connected to it, the worm gear 2132b is connected to the first gear 2132c, and the first gear 2132c is connected to the rotation shaft of the traveling wheel 2121.

[0137] For example, the first gear 2132c can be a worm gear structure.

[0138] It should be noted that the gear set 2132a can be used to adjust the transmission ratio between the first motor 2131 and the worm gear 2132b. For example, the transmission ratio between the first motor 2131 and the worm gear 2132b can be adjusted by controlling the number of gears in the gear set 2132a. This allows for the selection of a suitable first motor 2131 and gear set 2132a according to specific needs, thereby improving the design flexibility of the first transmission component 2132 and enhancing the performance of the first drive component 213.

[0139] The combination of gear set 2132a and worm gear 2132b effectively transmits the output torque of the first motor 2131 to the traveling wheel 2121. This ensures efficient power transmission and improves the operating efficiency of the cleaning equipment 100. The worm gear 2132b transmission has a significant ability to reduce speed and increase torque, which is particularly important for the cleaning equipment 100, which requires greater driving force. Through this transmission method, the traveling wheel 2121 can obtain greater torque output to cope with different terrains and loads. The worm gear 2132b transmission has a self-locking characteristic, meaning that the traveling wheel 2121 will not rotate in the opposite direction when no external force is applied, which helps to improve the stability of the wiping assembly 20 on slopes or uneven ground and prevents accidental slippage.

[0140] For ease of description, the x-direction in the figure is taken as the axis of the worm 2132b, and the y-direction is taken as the axis of the connecting shaft 2123. The x-direction is perpendicular to the y-direction, and the z-direction is also perpendicular to the y-direction.

[0141] like Figure 6As shown, the first drive assembly 213 may include a mounting base 2133, which may include mounting plates 2133a spaced apart from each other along the axial direction (x-direction) of the worm 2132b. The mounting plates 2133a are fixedly connected to the support plate 2122b. The worm 2132b is disposed between the two mounting plates 2133a, and the first gear 2132c is also located between the two mounting plates 2133a. The first gear 2132c is fixedly connected to the connecting shaft 2123 and meshes with the worm 2132b. The first motor 2131 is disposed on the top of the mounting base 2133, and the output shaft of the first motor 2131 is parallel to the axial direction of the worm 2132b. In the x-direction, the gear set 2132a is located at one end of the worm 2132b, and the gear set 2132a is drively connected to the output shaft of the first motor 2131 and the worm 2132b.

[0142] For example, the gear set 2132a can be embedded inside the mounting plate 2133a located on the side of the output shaft, so that the mounting plate 2133a can provide a certain degree of protection for the gear set 2132a and prevent dust from entering the gear set 2132a.

[0143] It should be noted that, in this embodiment of the application, the number of gears in the gear set 2132a is not further limited.

[0144] In one possible implementation, the traveling bracket 2122 and the fixed base 211 are movably connected in the height direction (z-direction) of the equipment body 10, and the traveling bracket 2122 and the fixed base 211 are rotatably connected in the circumferential direction of the fixed base 211. That is, the traveling bracket 2122 can move relative to the fixed base 211 in the z-direction. The traveling bracket 2122 can also rotate relative to the fixed base 211, with its axis of rotation parallel to the z-direction. The traveling mechanism 21 may further include a second drive assembly 214. The second drive assembly 214 is drively connected to the traveling bracket 2122 and is used to drive the traveling bracket 2122 to rotate the traveling wheel 2121 along the circumferential direction of the fixed base 211.

[0145] For example, the fixed base 211 can be a cylindrical structure, with the central axis of the fixed base 211 parallel to the z-direction. When the traveling bracket 2122 drives the traveling wheel 2121 to rotate around the circumference of the fixed base 211, the traveling bracket 2122 rotates around the central axis of the fixed base 211.

[0146] The walking bracket 2122 is movably connected to the fixed base 211 in the height direction of the equipment body 10. The walking wheel assembly 212 can float in the vertical direction, allowing the equipment to adjust its height when encountering obstacles. It can provide cushioning when the cleaning equipment 100 encounters obstacles, reducing physical wear and impact, improving the durability of the equipment, and better adapting to different terrains and cleaning needs. The walking bracket 2122 is rotatably connected to the fixed base 211 in the circumferential direction and is driven by the second drive assembly 214, allowing the walking wheels 2121 to rotate 360 ​​degrees around the equipment body 10. This gives the walking wheels 2121 omnidirectional mobility, allowing the wiping assembly 20 to flexibly turn and move in narrow or complex spaces.

[0147] See also Figure 5 and Figure 6 As shown, the walking support 2122 may include a support body 2122a, a first connecting member 2122d, a second connecting member 2122e, and an elastic member 2122f. The support body 2122a is rotatably connected to the walking wheels 2121. One end of the first connecting member 2122d is fixedly connected to the support body 2122a, and the other end passes through and is movably connected to the second connecting member 2122e. The second connecting member 2122e is rotatably connected to the fixed base 211 in the circumferential direction of the fixed base 211. The elastic member 2122f is sleeved on the outside of the first connecting member 2122d, and is located between the support body 2122a and the second connecting member 2122e in the height direction (z-direction) of the equipment body 10. The elastic member 2122f is extendable and retractable in the height direction (z-direction) of the equipment body 10.

[0148] The elastic element 2122f provides cushioning between the second connector 2122e and the support body 2122a. When the cleaning device 100 moves on uneven ground or encounters obstacles, the elastic element 2122f absorbs impact, reducing physical damage to the cleaning device 100 and improving its durability. The elastic element 2122f is extendable in the height direction of the device body 10, allowing the walking support 2122 to automatically adjust its height to adapt to different terrain changes. This design enables the device to maintain stable cleaning performance under various ground conditions. The combination of the first connector 2122d and the second connector 2122e makes the connection between the support body 2122a and the fixed base 211 more flexible.

[0149] For example, the first connector 2122d can be a rod-shaped structure, and the second connector 2122e can be a circular plate-shaped structure. The second connector 2122e has a through hole, through which the first connector 2122d passes and is movably connected in the z-direction; that is, the first connector 2122d can move within the through hole along the z-direction. One end of the first connector 2122d facing the support body 2122a is fixedly connected to the support body 2122a, and the other end of the first connector 2122d is located on the side of the second connector 2122e facing away from the support body 2122a. The elastic member 2122f is located outside the first connector 2122d, and in the z-direction, one end of the elastic member 2122f abuts against the second connector 2122e, and the other end abuts against the support body 2122a.

[0150] For example, the elastic element 2122f can be a spring structure. A wear-resistant element 2122g can be provided between the through hole of the second connector 2122e and the first connector 2122d. The material of the wear-resistant element 2122g can be rubber, plastic, etc., which can reduce the wear between the first connector 2122d and the second connector 2122e and extend the service life of the wiping assembly 20.

[0151] In some embodiments, the wear-resistant part 2122g can be a ring structure. In this application embodiment, the specific structure of the wear-resistant part 2122g is not further limited.

[0152] By setting the first connector 2122d as a rod-shaped structure, its structure can be simplified, materials can be saved, and costs can be reduced. By setting the second connector 2122e as a circular plate-shaped structure, a stable support surface can be provided, ensuring the stability of the walking bracket 2122. The circular plate-shaped structure of the second connector 2122e allows for smooth rotation in the circumferential direction of the fixed base 211, allowing the walking wheels 2121 to move freely around the equipment, improving the flexibility and mobility of the equipment. In addition, the circular plate-shaped structure can evenly distribute the force from the first connector 2122d and the elastic member 2122f, thereby reducing local stress concentration and lowering the risk of material fatigue and damage. Since the first connector 2122d is a rod-shaped structure, the elastic member 2122f can be more effectively fitted onto its outer side, achieving better telescopic function. This enhances the automatic adjustment capability of the cleaning equipment 100 in the height direction.

[0153] In one possible implementation, such as Figure 6As shown, the mounting base 211 may include a top plate 2111 and a side wall 2112, the side wall 2112 being disposed around the top plate 2111, and the top plate 2111 being fixedly connected to the side wall 2112. A second connecting member 2122e is located within the area enclosed by the side wall 2112 and is rotatably connected to the side wall 2112. The top plate 2111 is used for detachable connection to the equipment body 10.

[0154] For example, the inner side of the sidewall 2112 is provided with a groove 2112a arranged circumferentially along the sidewall 2112. The second connecting member 2122e is movably disposed within the groove 2112a, so that the second connecting member 2122e is rotatably connected to the sidewall 2112. This enables the second connecting member 2122e to be rotatably connected to the fixed base 211. Thus, when the second connecting member 2122e rotates relative to the fixed base 211, it can drive the walking bracket 2122 to rotate circumferentially along the fixed base 211, thereby achieving the purpose of steering the walking wheel 2121.

[0155] It should be noted that the groove 2112a can be directly formed on the inner side of the side wall 2112, or it can be set on a component fixed on the inner side of the side wall 2112. In this embodiment, the setting form of the groove 2112a is not further limited.

[0156] Of course, in other embodiments, the second connector 2122e can also be rotatably connected to the fixed base 211 in other ways. For example, a slide rail can be provided on the inner side of the side wall 2112, and the second connector 2122e can be rotatably connected to the side wall 2112 via the slide rail. In the embodiments of this application, the connection method between the second connector 2122e and the fixed base 211 is not further limited.

[0157] This configuration, with the top plate 2111 and side wall 2112 fixedly connected, forms a robust frame structure, providing excellent mechanical stability and effectively supporting the weight and motion load of the traveling bracket 2122 and other components. The traveling bracket 2122 and side wall 2112 rotate circumferentially along the fixed base 211, providing a stable rotation path and ensuring the smoothness and accuracy of the traveling bracket 2122 during rotation. The side wall 2112 surrounds the top plate 2111, forming a compact whole. This design saves space, allowing the traveling mechanism 21 to achieve complex motion functions within a limited space. The top plate 2111 is detachably connected to the main body 10 of the equipment, making the installation and disassembly of the fixed base 211 and other components more convenient. This design simplifies the equipment maintenance and parts replacement process.

[0158] It should be noted that in the embodiments of this application, "orientation" refers to orientation in a broad sense and is not limited to a front-facing arrangement, and "away from" refers to away from in a broad sense and is not limited to a back-to-back parallel arrangement.

[0159] In one possible implementation, see Figure 7 As shown, the second drive assembly 214 may include a second motor 2141 and a second transmission assembly 2142. The second motor 2141 is drivenly connected to the second transmission assembly 2142, and the second transmission assembly 2142 is drivenly connected to the walking bracket 2122. The second motor 2141 is used to drive the walking bracket 2122 to rotate circumferentially along the fixed base 211 through the second transmission assembly 2142.

[0160] For example, the second drive assembly 214 is fixedly connected to the walking bracket 2122. For instance, the second drive assembly 214 is located on the side of the bracket body 2122a away from the first drive assembly 213. That is, a first drive assembly 213 and a second drive assembly 214 are respectively provided on both sides of the walking bracket 2122. This allows the bracket body 2122a to have a drive assembly on each side of the walking wheel 2121 along the axial direction, which can balance the weight on both sides of the walking wheel 2121 along the axial direction, improve the stability of the wiping cloth assembly 20, and prevent the wiping cloth assembly 20 from tipping over.

[0161] The second motor 2141 drives the walking bracket 2122 to rotate circumferentially along the fixed base 211, enabling the walking mechanism 21 to achieve 360-degree rotation. In other words, the walking mechanism 21 can turn freely on the surface to be cleaned, making it easier to change the path of the walking mechanism 21 and improving its obstacle avoidance performance. This allows the walking mechanism 21 to flexibly turn the wiping cloth assembly 20 in confined or complex spaces, allowing it to cover a wider area and improving cleaning efficiency and coverage. The combination of the second motor 2141 and the second transmission assembly 2142 makes precise control of the rotation direction and speed of the walking bracket 2122 possible. This precision helps optimize the cleaning path, reducing repetitive cleaning and missed areas.

[0162] For example, the second transmission assembly 2142 may include a second gear 2142a and a third gear 2142b. The second motor 2141 is fixedly connected to the traveling bracket 2122, and the output shaft of the second motor 2141 is driven by the second gear 2142a. The second gear 2142a is movably connected to the traveling bracket 2122. The third gear 2142b is fixedly connected to the fixed base 211, and the second gear 2142a and the third gear 2142b are meshed together. The second motor 2141 drives the second gear 2142a to rotate circumferentially along the third gear 2142b, thereby causing the traveling bracket 2122 to rotate circumferentially along the fixed base 211.

[0163] For example, the walking bracket 2122 is rotatably connected to the side wall 2112 of the fixed base 211 along the circumference of the fixed base 211. Figure 7 The second drive assembly 214 is fixedly mounted on the second connector 2122e. The second motor 2141 is located on the side of the second connector 2122e facing the traveling bracket 2122, while the second gear 2142a and the third gear 2142b are located on the side of the second connector 2122e facing away from the traveling bracket 2122. That is, the second gear 2142a and the third gear 2142b are located within the space enclosed by the side wall 2112 of the fixed base 211. The second connector 2122e is rotatably connected to the side wall 2112 of the fixed base 211, and the traveling bracket 2122 is fixedly connected to the second connector 2122e. This allows the traveling bracket 2122 to be rotatably connected to the fixed base 211.

[0164] The second gear 2142a is movably disposed on the side of the traveling bracket 2122 opposite to the second connecting member 2122e. The third gear 2142b is fixedly connected to the top plate 2111, and the second gear 2142a meshes with the third gear 2142b. When the second gear 2142a rotates, since the third gear 2142b is fixed to the top plate 2111 and cannot rotate, while the second connecting member 2122e can rotate relative to the fixed seat 211, the second gear 2142a drives the second connecting member 2122e to rotate around the circumference of the third gear 2142b, thereby driving the traveling bracket 2122, which is fixed to the second connecting member 2122e, to rotate around the circumference of the fixed seat 211, thus realizing the steering of the traveling wheel 2121. During the movement of the traveling bracket 2122, the second drive assembly 214 rotates around the central axis of the third gear 2142b along with the traveling bracket 2122 and the second connecting member 2122e.

[0165] Through the meshing connection of the second gear 2142a and the third gear 2142b, the output of the second motor 2141 can be effectively transmitted to the traveling bracket 2122, achieving efficient power transmission and ensuring the smooth rotation of the traveling bracket 2122. The arrangement of the first gear 2132c and the second gear 2142a allows for precise control of the rotation of the traveling bracket 2122. By adjusting the gear ratio, the traveling mechanism 21 can achieve different rotational speeds and directions to meet the needs of various cleaning tasks. The third gear 2142b is fixedly connected to the fixed base 211, providing a stable reference point, which helps improve the stability of the traveling bracket 2122 during rotation and reduces vibration and deviation. Gear transmission systems can often be designed to be very compact, saving space. This compactness helps reduce the overall size of the equipment, facilitating operation in confined spaces. In some designs, gear transmission systems can have a self-locking characteristic, meaning that the traveling bracket 2122 will not rotate in the opposite direction when no external force is applied. This characteristic helps improve the stability of the equipment and prevents accidental slippage.

[0166] For example, multiple transmission components may be included between the second motor 2141 and the second transmission assembly 2142 to transmit power from the second motor 2141 to the second transmission assembly 2142. In this embodiment, the specific structure of the multiple transmission components between the second motor 2141 and the second transmission assembly 2142 is not further limited. Any component that can transmit power from the second motor 2141 to the second transmission assembly 2142 is acceptable.

[0167] In one possible implementation, such as Figure 8 and Figure 9 As shown, the fixing member 40 has a connecting portion 41 on the side facing the cloth assembly 20. The cloth assembly 20 may include a locking portion 23 that cooperates with the connecting portion 41. When the cloth assembly 20 is fixedly connected to the fixing member 40, the connecting portion 41 and the locking portion 23 are engaged. When the cloth assembly 20 is disengaged from the fixing member 40, the connecting portion 41 and the locking portion 23 are separated.

[0168] This design, with the interlocking mechanism between the connecting part 41 and the locking part 23, allows users to quickly install and remove the cloth assembly 20. The interlocking connection provides a secure fixation, ensuring that the cloth assembly 20 will not accidentally detach during operation, improving the safety and reliability of the cleaning process. The installation and removal of the cloth assembly 20 can be completed without tools, simplifying the operation and enhancing the user experience. The interlocking connection design typically includes an anti-misoperation function to prevent the cloth assembly 20 from detaching under improper circumstances, ensuring the safe operation of the cleaning equipment 100.

[0169] For example, the connecting part 41 can be a column structure extending toward the cloth assembly 20. The locking part 23 is a groove structure, and the groove structure is open at one end of the fixing base 211 in the circumferential direction. The column structure enters the groove structure from the opening and engages with the groove structure.

[0170] In some embodiments, there are multiple locking portions 23, which are spaced apart circumferentially along the fixing base 211. Correspondingly, there are also multiple connecting portions 41, and the number of connecting portions 41 is equal to the number of locking portions 23. That is, one connecting portion 41 corresponds to one locking portion 23, which can improve the connection stability between the connecting portion 41 and the locking portion 23.

[0171] The installation process is intuitive and simple by designing the column structure to be accessible through the opening in the recessed structure. Simply screw the column structure into the recessed structure through the opening, and the column and recessed structure will engage, allowing for quick installation and preventing the cloth assembly 20 from falling off unnecessarily. The engagement between the column structure and the recessed structure provides a secure connection, ensuring that the cloth assembly 20 will not accidentally fall off during use. This stability improves the reliability and safety of the cleaning equipment 100. Because the recessed structure opens only at one end, the column structure must be inserted from a specific direction; this design reduces the possibility of misoperation and ensures the correct installation of the cloth assembly 20.

[0172] In one possible implementation, the locking part 23 is fixedly connected to the wheel assembly 212, and the locking part 23 is movably connected to the fixed base 211. The fixed base 211 is provided with an assembly hole 2113 for the connecting part 41 to pass through.

[0173] For example, the locking part 23 is fixedly disposed on the side of the second connector 2122e facing the top plate 2111. When the second connector 2122e rotates relative to the fixed base 211, it can drive the locking part 23 to rotate relative to the fixed base 211. The top plate 2111 of the fixed base 211 is provided with an assembly hole 2113. When the wiping cloth assembly 20 is opposite to the fixing member 40, the connecting part 41 on the fixing member 40 enters the space enclosed by the side wall 2112 of the fixed base 211 through the assembly hole 2113. The connecting part 41 and the locking part 23 can be locked together by adjusting the second connector 2122e.

[0174] It should be noted that since an elastic element 2122f is provided between the second connecting member 2122e and the traveling bracket 2122, the distance between the traveling bracket 2122 and the fixed seat 211 can be varied, thereby giving the traveling wheel 2121 a certain degree of floating in the z direction.

[0175] For example, during the process of the fastener 40 and the fixing seat 211 moving from a separated state to a connected state, the connecting part 41 abuts against the top plate 2111, causing the entire cloth assembly 20 to move downwards. At this time, the elastic member 2122f can be compressed, allowing the connecting part 41 to move on the top plate 2111 until a portion of the connecting part 41 enters the mounting hole 2113. Then, the holding force of the connecting part 41 against the top plate 2111 disappears, and the fixing seat 211 and the second connecting member 2122e move towards the fastener 40, so that a portion of the connecting part 41 is opposite the locking part 23. Then, by rotating the second connecting member 2122e, the connecting part 41 and the locking part 23 are locked together.

[0176] In one possible implementation, when the connecting part 41 is locked to the locking part 23, the structure of the connecting part 41 and the locking part 23 allows the connecting part 41 to gradually drive the locking part 23 to move closer to the fixing member 40, thereby allowing the elastic member 2122f to be in a stretched state, so that the elastic member 2122f has a downward restoring force. When the connecting part 41 is separated from the locking part 23, the second connecting member 2122e moves away from the fixing member 40 under the action of the restoring force of the elastic member 2122f, thereby driving the fixing seat 211 to move away from the fixing member 40, so that part of the structure of the connecting part 41 is disengaged from the assembly hole 2113. Then, the second connecting member 2122e is driven to rotate, so that the connecting part 41 can be disengaged from the assembly hole 2113. Of course, during the process of the connecting part 41 disengaging from the mounting hole 2113, the connecting part 41 can drive the top plate 2111 of the fixing base 211 to move away from the fixing member 40, or drive the fixing base 211 to move away from the fixing member 40 through other components, so that the connecting part 41 disengages from the mounting hole 2113.

[0177] In this embodiment, the specific structure of how the connecting part 41 disengages from the mounting hole 2113 when it separates from the locking part 23 is not further described. It is sufficient that the connecting part 41 can disengage from the mounting hole 2113 when it separates from the locking part 23.

[0178] This configuration allows for a certain degree of free movement in the movable connection between the locking part 23 and the fixed base 211. When the connecting part 41 is inserted into the mounting hole 2113, the locking part 23 can be engaged or disengaged from the connecting part 41 by rotating the traveling wheel assembly 212. The entire process can be completed automatically by the traveling mechanism 21 without manual operation. This allows the cleaning device 100's cloth assembly 20 to automatically switch between normal and extended modes according to cleaning needs, improving the automation of the cleaning device 100 and enhancing the user experience.

[0179] In one possible implementation, the cloth assembly 20 may include a third drive assembly 24 (see also...). Figure 6 (As shown). The third drive assembly 24 is arranged around the outside of the walking mechanism 21 and is fixedly connected to the fixed base 211. The third drive assembly 24 is connected to the cleaning component 22 for transmission, and is used to drive the cleaning component 22 to rotate to perform cleaning operations.

[0180] In this configuration, the third drive assembly 24 is specifically designed to drive the rotation of the cleaning component 22, making the cleaning function independent of the movement of the walking mechanism 21. This independence allows for more precise and efficient cleaning operations, improving cleaning results. The rotational movement of the cleaning component 22 can cover a larger cleaning area, reducing missed areas and improving overall cleaning efficiency. By rotating the cleaning component 22, different cleaning paths and modes can be achieved to adapt to different floor materials and cleaning needs. The open design in the middle of the cleaning component 22 allows the walking mechanism 21 to directly contact the surface to be cleaned, reducing friction and wear between the cleaning component 22 and the ground, and extending the service life of the cleaning component 22. The design of the third drive assembly 24 can accommodate cleaning components 22 of different types and shapes, enabling the equipment to flexibly handle various cleaning tasks. The design of the mounting base 211 ensures that the third drive assembly 24 is securely installed, avoiding the risk of loosening or falling off during operation.

[0181] For example, the connecting component 30 can be fixed to the outside of the third drive component 24 (see...). Figure 3 As shown), the connecting component 30 can also be fixed to the outside of the side wall 2112 of the fixing base 211 (see Figure 2112). Figure 2 As shown in the figure, in this embodiment of the application, the specific location of the connecting component 30 is not further limited.
