[0001] Cross-reference of related applications

[0002] This application claims the benefit of Chinese Patent Application No. 202511373853.4, filed on September 24, 2025, the contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the technical field of cleaning equipment, and more particularly to a control method for cleaning equipment and a cleaning equipment. Background Technology

[0004] In cleaning equipment applications, these devices typically encounter specific obstacles during wet cleaning operations. These obstacles can be slightly protruding from the ground (such as low thresholds or floor decorations) or guide panels on base stations. When cleaning equipment passes these obstacles, its obstacle avoidance mechanisms limit its ability to avoid them, often causing it to simply pass over them. This can result in wastewater on the cleaning equipment being scraped off the obstacle, flowing onto the ground and contaminating the area. Carpets are another type of obstacle. When wet cleaning equipment passes over carpets, it can easily wet the carpet, allowing wastewater to seep into the carpet fibers and cause carpet stains.

[0005] Therefore, how to effectively improve the problem of cleaning equipment easily causing pollution in the passage area when passing through specific obstacles is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] This invention provides a control method and a cleaning device to improve the technical problem that the cleaning device easily causes pollution to the passage area when it passes through specific obstacles during its movement.

[0007] This invention provides a control method for a cleaning device. The cleaning device includes a frame, a rotary cleaning component, and a shielding mechanism. The rotary cleaning component is mounted on the bottom of the frame and has a first rotation direction and a second rotation direction. The rotary cleaning component includes a first connecting member that moves in conjunction with the rotary cleaning component. The shielding mechanism is mounted on the frame and includes a shielding member that can be extended and retracted under the drive of the shielding mechanism to expose or shield the side of the rotary cleaning component facing the surface to be cleaned. The shielding member includes a second connecting member. When it is necessary to use the shielding member to shield the side of the rotary cleaning component facing the surface to be cleaned, the control method includes:

[0008] The blocking mechanism is controlled to lower the blocking component so that the second connecting component aligns with and connects to the first connecting component on the movement path of the first connecting component.

[0009] The rotary cleaning component is driven to move along the first rotation direction, and the shielding component continues to be lowered through the connection of the first connector and the second connector to shield the side of the rotary cleaning component facing the surface to be cleaned.

[0010] The second rotation direction refers to the rotation direction of the rotary cleaning component when performing wet cleaning tasks, and the first rotation direction is opposite to the second rotation direction.

[0011] The beneficial effects of this design are as follows: In this embodiment, when the cleaning equipment needs to pass through specific obstacles (such as thresholds or carpets) during its movement, the blocking mechanism can be controlled to lower the blocking component, connecting the second connector with the first connector. Subsequently, the rotating cleaning component is driven to move along the first rotation direction. Through the connection between the first and second connectors, the blocking component continues to lower, thus blocking the rotating cleaning component from the surface to be cleaned, thereby isolating the rotating cleaning component from the ground. Therefore, the probability of wastewater being blown onto the ground and contaminating the passageway when the wet rotating cleaning component passes through specific obstacles can be reduced. In particular, it can reduce the probability of wastewater dripping onto the carpet when the wet rotating cleaning component passes through it, as well as the probability of long fibers on the carpet coming into contact with the rotating cleaning component, thereby reducing the risk of carpet contamination.

[0012] Furthermore, since the second rotation direction is the same as the rotation direction of the rotary cleaning component when performing wet cleaning tasks, and the first rotation direction is opposite to the second rotation direction, this setting ensures that the blocking action is only triggered when the rotary cleaning component is not performing wet cleaning tasks (i.e., running in a direction other than the second rotation direction). This avoids the risk of the blocking component interfering with the normally rotating rotary cleaning component due to accidental lowering during normal wet cleaning operations, thus ensuring the normal wet cleaning operation of the rotary cleaning component.

[0013] Optionally, controlling the blocking mechanism to lower the blocking member so that the second connecting member aligns with and connects to the first connecting member on the movement path of the first connecting member includes:

[0014] Drive the rotary cleaning component to move in a first rotational direction, so that the rotary cleaning component drives the first connecting component to move in the first rotational direction;

[0015] The control mechanism lowers the blocking component, causing the second connecting component to move onto the movement path of the first connecting component. During the movement of the first connecting component in the first rotation direction, the second connecting component connects to the first connecting component on the movement path of the first connecting component.

[0016] The beneficial effects of this setup are as follows: By first driving the rotary cleaning component to put the first connector into motion, and then controlling the lowering of the shielding mechanism to send the second connector into the motion path of the first connector, this timing control allows the second connector to dynamically dock with the first connector during its movement. This shortens the response time for the connection between the first and second connectors and makes the connection action smoother and more natural, thereby improving the connection efficiency between the first and second connectors.

[0017] Optionally, controlling the blocking mechanism to lower the blocking member so that the second connecting member aligns with and connects to the first connecting member on the movement path of the first connecting member includes:

[0018] Control the blocking mechanism to lower the blocking component, so that the second connecting component moves onto the movement path of the first connecting component;

[0019] The rotary cleaning component is driven to move in a first rotation direction, so that the rotary cleaning component drives the first connecting component to move in the first rotation direction. During the movement of the first connecting component in the first rotation direction, the second connecting component is connected to the first connecting component on the movement path of the first connecting component.

[0020] The beneficial effects of this setup are as follows: by first moving the second connector onto the movement path of the first connector, and then controlling the movement of the first connector to achieve connection with the second connector, this control helps ensure the accurate positioning of the second connector and avoids motion interference between the second connector and the first connector during operation. This helps improve the docking position accuracy between the first and second connectors and reduces the risk of connection failure between the first and second connectors.

[0021] Optionally, the linear velocity of the first connecting member moving along the first rotation direction is greater than or equal to the speed at which the blocking mechanism lowers the blocking member.

[0022] The beneficial effects of this design are as follows: During the continuous lowering of the blocking component, because the linear velocity of the first connecting member moving along the first rotational direction is always greater than or equal to the speed at which the blocking mechanism lowers the blocking component, this velocity relationship ensures that the blocking component is always in a "taut" state. Therefore, the blocking component will not experience any slack sections during the entire lowering process, effectively reducing the risk of scratching or entanglement that may be caused by the blocking component sagging. At the same time, this taut state also helps to ensure the continuity and stability of the lowering action of the blocking component, thereby improving the reliability and stability of the blocking component in performing the blocking action.

[0023] Optionally, along the forward direction of the cleaning equipment, one end of the cleaning equipment is the front end and the other end is the rear end; the shielding component is retracted at the front end; the rotary cleaning component includes a first arc-shaped segment, a second arc-shaped segment, a first flat segment, and a second flat segment. The first arc-shaped segment and the second arc-shaped segment are distributed sequentially from the front end to the rear end. The first flat segment connects between the first arc-shaped segment and the second arc-shaped segment and is located close to the surface to be cleaned. The second flat segment connects between the first arc-shaped segment and the second arc-shaped segment and is located on the side of the first flat segment away from the surface to be cleaned.

[0024] The rotary cleaning component is driven to move along a first rotation direction, and the shielding component continues to descend through the connection of the first and second connecting components to shield the side of the rotary cleaning component facing the surface to be cleaned, including:

[0025] The blocking component passes through and blocks the first arc segment, the first planar segment, and the second arc segment in sequence.

[0026] The beneficial effects of this design are as follows: During the process of shielding the rotating cleaning component, the shielding member can sequentially cover the contours of the first arc-shaped segment, the first flat segment, and the second arc-shaped segment, ultimately stopping at the position corresponding to the second arc-shaped segment. In this state, a matching arc-shaped shielding structure can be formed between the shielding member and the second arc-shaped segment. This arc-shaped shielding structure can effectively catch the wastewater dripping from the second arc-shaped segment corresponding to the rotating cleaning component and gather it inside the shielding member, thereby improving the shielding effect of the shielding member on the side of the rotating cleaning component facing the surface to be cleaned. Simultaneously, the arc-shaped shielding structure can also reduce the risk of wastewater gathered inside the shielding member leaking out during the movement of the cleaning equipment, further enhancing the shielding effect of the shielding member on the side of the rotating cleaning component facing the surface to be cleaned.

[0027] Optionally, after using a shielding member to cover the side of the rotary cleaning member facing the surface to be cleaned, when it is necessary to expose the side of the rotary cleaning member facing the surface to be cleaned, the control method further includes:

[0028] Drive the rotary cleaning component to move in the second rotation direction, and control the shielding mechanism to retract the shielding component until the shielding component exposes the rotary cleaning component to the side facing the surface to be cleaned.

[0029] The second rotation direction is opposite to the first rotation direction, and the second rotation direction is consistent with the rotation direction of the rotary cleaning component when performing the cleaning task.

[0030] The advantages of this design are as follows: Since the rotary cleaning component can only perform cleaning tasks when the side facing the surface to be cleaned is exposed, in this embodiment, the second rotation direction is set to be consistent with the rotation direction of the rotary cleaning component when performing the cleaning task. This means that when the blocking component retracts, the rotary cleaning component is already rotating in the second rotation direction required for performing the cleaning task. With this design, once the side of the rotary cleaning component facing the surface to be cleaned is exposed, it can immediately begin cleaning without needing to change direction. Therefore, the control logic for the operation of the cleaning equipment can be simplified, and the cleaning efficiency of the cleaning equipment can also be improved.

[0031] Optionally, the linear velocity of the first connecting member moving in the second rotational direction is less than or equal to the speed at which the blocking mechanism retracts the blocking member.

[0032] The beneficial effects of this design are as follows: Since the linear velocity of the first connecting member moving along the second rotational direction is always less than or equal to the speed at which the blocking mechanism retracts the blocking member, this velocity relationship ensures that the blocking member is always in a "taut" state. Therefore, the blocking member will not have any slack sections during the entire retraction process, effectively reducing the risk of scratching or entanglement that may be caused by the blocking member sagging. At the same time, this taut state also helps to ensure the continuity and stability of the blocking member's retraction action, thereby improving the reliability and consistency of the blocking member's retraction action.

[0033] Optionally, the control method further includes driving the rotary cleaning component to move in a second rotational direction and controlling the shielding mechanism to retract the shielding component until the shielding component exposes the rotary cleaning component to the side facing the surface to be cleaned.

[0034] Continue to drive the rotary cleaning component to move in the second rotation direction and control the shielding mechanism to continue retracting the shielding component until the first connector and the second connector disengage.

[0035] The beneficial effects of this design are as follows: It allows for the automatic disengagement of the first and second connecting parts during the movement of the rotary cleaning component along the second rotation direction. This process eliminates the need for additional operations or complex control commands, thus simplifying the control logic of the control system. Simultaneously, since the first and second connecting parts disengage, the rotational motion of the rotary cleaning component and the retraction action of the blocking component are completely decoupled, becoming two independent motion processes. This allows the rotary cleaning component to operate continuously along the second rotation direction (i.e., the cleaning direction) without interference, no longer affected by the retraction action of the blocking component. This effectively avoids cleaning interruptions, speed fluctuations, or operational malfunctions that may be caused by linkage limitations, thereby significantly improving the continuity of the cleaning process and overall operational efficiency.

[0036] Optionally, along the forward direction of the cleaning equipment, one end of the cleaning equipment is the front end and the other end is the rear end; the shielding component is retracted at the front end; the rotary cleaning component includes a first arc-shaped segment, a second arc-shaped segment, a first flat segment, and a second flat segment. The first arc-shaped segment and the second arc-shaped segment are distributed sequentially from the front end to the rear end. The first flat segment connects between the first arc-shaped segment and the second arc-shaped segment and is located close to the surface to be cleaned. The second flat segment connects between the first arc-shaped segment and the second arc-shaped segment and is located on the side of the first flat segment away from the surface to be cleaned.

[0037] Driving the rotary cleaning component to move in a second rotational direction and controlling the shielding mechanism to retract the shielding component until the shielding component exposes the rotary cleaning component to the side facing the surface to be cleaned, including:

[0038] The shielding component moves away from and exposes the second arc segment, the first planar segment, and the first arc segment in sequence.

[0039] The beneficial effects of this design are as follows: As the shielding component retracts, it sequentially moves away from and exposes the second arc segment, the first flat segment, and the first arc segment. This design ensures that the side of the rotating cleaning component facing the surface to be cleaned is completely exposed. This means that during normal cleaning operations, the shielding component will not interfere with the cleaning function of the rotating cleaning component, thereby ensuring the efficiency and effectiveness of the cleaning operation.

[0040] Optionally, the cleaning equipment is also equipped with a sensor system for identifying image and / or three-dimensional information of obstacles, and the control method further includes:

[0041] The sensor system is used to detect image information and / or three-dimensional information of obstacles, and the type of obstacle is determined based on the image information and / or three-dimensional information of the obstacle;

[0042] Determine whether it is necessary to block the side of the rotating cleaning component facing the surface to be cleaned based on the type of obstacle.

[0043] The beneficial effects of this setup are as follows: By installing a sensor system on the cleaning equipment, which can be used to identify the image information and / or three-dimensional information of obstacles, the cleaning equipment can automatically and accurately determine the type of obstacle and, based on this determination, decide whether a blocking device is needed to block the rotating cleaning device. Therefore, this helps to improve the intelligence level, safety, and adaptability of the cleaning operation process.

[0044] In addition, the present invention also provides a cleaning device, including a frame, a rotary cleaning component, an inner support mechanism, and a shielding mechanism; the inner support mechanism is installed on the frame, and the rotary cleaning component is sleeved outside the inner support mechanism, which is used to drive the rotary cleaning component to rotate; the shielding mechanism includes a shielding member, which is retractably installed on the frame and has a first state and a second state. In the first state, the shielding member exposes the side of the rotary cleaning component facing the surface to be cleaned; in the second state, the shielding member blocks the side of the rotary cleaning component facing the surface to be cleaned. The rotary cleaning component includes a first connecting member that is linked to the rotary cleaning component, and the shielding member includes a second connecting member. The first and second connecting members have a connected state and a disconnected state. In the connected state, the shielding member is linked to the rotary cleaning component to achieve switching between the first and second states; in the disconnected state, the first connecting member is disconnected from the second connecting member to release the linkage between the shielding member and the rotary cleaning component.

[0045] The beneficial effects of this design are as follows: Firstly, during the operation of the cleaning equipment, when the rotating cleaning component passes over a specific obstacle, the shielding component can be in a second state, blocking the side of the rotating cleaning component facing the surface to be cleaned, thereby isolating the rotating cleaning component from the ground. This reduces the probability of wastewater being blown onto the ground and contaminating the passageway when the wet rotating cleaning component passes over a specific obstacle. In particular, it reduces the probability of wastewater dripping onto carpets when the wet rotating cleaning component passes over carpets, and the probability of long fibers on the carpet coming into contact with the rotating cleaning component, thus reducing the risk of carpet contamination. Furthermore, when the cleaning equipment passes over other areas unsuitable for wet cleaning (such as already cleaned areas, areas under furniture, or wooden floors that need to be kept dry), the above structure can also reduce the probability of wastewater dripping into these areas, thereby reducing the possibility of contamination.

[0046] On the other hand, by controlling the connection and disconnection of the first and second connecting parts, the shielding part and the rotary cleaning part can be linked, enabling them to automatically switch between the first and second states. Therefore, based on this linkage mechanism, an automatic pulling end can be formed at one end of the shielding part, eliminating the need for additional pulling or pushing mechanisms, thus simplifying the structural design of the cleaning equipment and reducing production costs.

[0047] Optionally, the rotary cleaning component has a first rotation direction and a second rotation direction, which are opposite to each other. When the shielding component switches from the first state to the second state, the rotary cleaning component rotates along the first rotation direction; when the shielding component switches from the second state to the first state, the rotary cleaning component rotates along the second rotation direction.

[0048] The beneficial effects of this setup are as follows: By controlling the rotation direction of the rotary cleaning component, the shielding component can be switched between the first and second states. Therefore, this method simplifies the control logic of the shielding component's operation, eliminating the need for operators or the control system to handle complex turning actions. This reduces the operational difficulty and error probability of switching the shielding component between different states, thereby improving the ease of use and reliability of the cleaning equipment.

[0049] Optionally, along the forward direction of the cleaning equipment, the rotary cleaning component includes a first arc-shaped segment, a second arc-shaped segment, a first flat segment, and a second flat segment. The first arc-shaped segment and the second arc-shaped segment are distributed horizontally. The first flat segment connects between the first arc-shaped segment and the second arc-shaped segment and is located close to the surface to be cleaned. The second flat segment connects between the first arc-shaped segment and the second arc-shaped segment and is located on the side of the first flat segment away from the surface to be cleaned. When the shielding component switches from the first state to the second state, the shielding component passes through and shields the first arc-shaped segment, the first flat segment, and the second arc-shaped segment in sequence. When the shielding component switches from the second state to the first state, the shielding component moves away from and exposes the second arc-shaped segment, the first flat segment, and the first arc-shaped segment in sequence.

[0050] The beneficial effects of this design are as follows: Firstly, in the first state, the shielding component completely exposes the side of the rotating cleaning component facing the surface to be cleaned. This means that during normal cleaning operations, the shielding component will not interfere with the cleaning function of the rotating cleaning component, ensuring cleaning efficiency and effectiveness. Secondly, in the second state, the shielding component can be arranged in an arc shape near the second arc section, shielding the outer periphery of the cleaning component. This structural design allows wastewater dripping from the rotating cleaning component to be effectively collected on the shielding component, thereby reducing the risk of wastewater leakage in the shielded state. In this way, the shielding component can better isolate the rotating cleaning component from the surface to be cleaned, improving the isolation effect.

[0051] Optionally, a mounting base is also connected to the frame. The mounting base has a receiving cavity, and the rotary cleaning component is rotatably installed in the receiving cavity. The shielding mechanism is located outside the receiving cavity. Along the forward direction of the cleaning equipment, when the shielding component is in the first state, the shielding component is located at the front end of the rotary cleaning component and is positioned close to the first arc surface segment.

[0052] The beneficial effects of this design are: it ensures that in the first state, the shielding component can completely expose the side of the rotating cleaning component facing the surface to be cleaned. This means that during normal cleaning operations, the shielding component will not interfere with the cleaning function of the rotating cleaning component, ensuring the efficiency and effectiveness of the cleaning operation.

[0053] Optionally, the rotary cleaning component includes a cleaning component body and an annular portion. The cleaning component body is used to clean the surface to be cleaned, and the annular portion is disposed at the end of the cleaning component body. A first connecting member is connected to the annular portion.

[0054] The advantages of this design are as follows: By providing an annular portion at the end of the cleaning component body and connecting the first connector to this annular portion, the installation position of the first connector relative to the cleaning component body can be flexibly adjusted by changing the shape and size of the annular portion. This reduces the likelihood of interference between the first connector and the cleaning component in the height or width directions. Simultaneously, this design also helps to reduce the occupancy or impact of the first connector on the effective cleaning surface of the cleaning component, thereby optimizing the overall structural layout of the rotary cleaning component and improving its compactness.

[0055] Optionally, the annular portion is fixedly connected to the cleaning component body, and the cleaning component body drives the annular portion to rotate synchronously during rotation; or, the annular portion and the cleaning component body are separately arranged, and the internal support mechanism drives the cleaning component body and the annular portion to rotate synchronously.

[0056] The advantages of this design are as follows: Because the annular portion is fixedly connected to the cleaning component body, there will be no relative displacement between the two during the rotation of the rotary cleaning component, resulting in better motion synchronization and improved efficiency in switching between the connected and disconnected states of the first and second connecting parts. Since the annular portion and the cleaning component body are designed as separate units, they can be independently installed on the internal support mechanism. This structural design allows the annular portion and the cleaning component body to be replaced independently when needed, without replacing the entire rotary cleaning component, thus reducing maintenance difficulty and costs.

[0057] Optionally, along the forward direction perpendicular to the cleaning equipment, the annular portion protrudes from the cleaning component body, and the length of the shielding component is greater than or equal to the length of the cleaning component body, but less than the maximum length of the rotary cleaning component.

[0058] The advantages of this design are twofold: First, it ensures that the shielding component fully covers the cleaning component when in its shielding state, effectively preventing wastewater from dripping onto the surface to be cleaned and ensuring the shielding effect. Second, since the length of the shielding component does not exceed the maximum range of the rotary cleaning component, it avoids occupying additional installation space along the length of the rotary cleaning component due to the shielding component, thus contributing to the compactness of the overall structure of the cleaning equipment.

[0059] Optionally, the projection of the annular portion along the length of the rotating cleaning component is located within the projection of the main body of the cleaning component.

[0060] The beneficial effect of this design is that it ensures that the annular part does not affect the effective cleaning area of ​​the cleaning component, thereby ensuring the cleaning efficiency of the cleaning component.

[0061] Optionally, the projection of the annular portion and the projection of the first connector along the length of the rotary cleaning component are both located within the projection of the cleaning component body.

[0062] The beneficial effects of this design are that it ensures that the arrangement of the annular part and the first connecting member will not affect the effective cleaning area of ​​the cleaning component, thereby further ensuring the cleaning efficiency of the cleaning component.

[0063] Optionally, along the forward direction perpendicular to the cleaning device, the cleaning component body includes a first end and a second end, and the shielding component includes a first side and a second side; at least one annular portion is provided at the first end and the second end respectively, and at least one second connecting member is provided at the first side and the second side respectively; or, at least one annular portion is provided at the first end or the second end, and at least one second connecting member is provided at the first side or the second side corresponding to the annular portion.

[0064] The beneficial effects of this design are as follows: Since each end of the cleaning component has an annular portion, and both sides of the shielding component have second connecting members, this arrangement allows for a connection between the first and second connecting members on both sides of the shielding component. This ensures that the connecting force is simultaneously and evenly transmitted from both sides to the cleaning component. This symmetrical structural design reduces localized stress concentration in the cleaning component caused by unilateral force application, ensuring uniform compression and thus guaranteeing stable cleaning performance. Furthermore, this design effectively reduces the risk of twisting, shifting, or connection failure of the shielding component due to uneven force application, thereby improving the operational stability of the shielding component.

[0065] Compared to designs with ring-shaped portions on both sides of the cleaning component, one embodiment employs a single-sided ring-shaped portion and a second connecting member. This approach, while ensuring basic functionality, offers advantages such as simplified structure, improved manufacturing and assembly efficiency, and reduced material costs. This design is particularly suitable for applications with strict limitations on installation space or manufacturing costs, providing greater flexibility in the overall layout of the cleaning equipment while maintaining the stability of the shielding component and the uniformity of the cleaning component's compression.

[0066] Optionally, multiple first connectors are provided on the annular portion, and the multiple first connectors are spaced apart along the outer periphery of the annular portion, and each first connector can be connected to or disconnected from the second connector.

[0067] The advantages of this arrangement are as follows: Compared to a scheme with a single first connector on the annular portion, this embodiment uses multiple first connectors along the outer periphery of the annular portion. When a first connector needs to mate with a second connector, the rotary cleaning component only needs to rotate a small angle to allow one of the first connectors to quickly approach and reliably connect with the second connector. Therefore, this layout improves the efficiency of the shielding component switching between the first and second states, enhancing operational convenience and response speed.

[0068] Optionally, the cleaning equipment also includes a guide, which is disposed on the frame and located on the outer periphery of the rotary cleaning component; the guide is used to guide the second connecting component closer to the rotary cleaning component during the lowering of the shielding component, so as to achieve connection with the first connecting component during the rotation of the rotary cleaning component.

[0069] The beneficial effects of this design are as follows: By incorporating a guide component, the second connector can be guided closer to the rotary cleaning component during the lowering of the shielding component, ensuring accurate connection between the second and first connectors. Since the guide component constrains and guides the movement path of the second connector during the lowering process, it reduces the probability of connection failure due to positional deviations in the second connector, thereby improving the reliability of the connection between them. Furthermore, because the guide component reduces positional errors during the movement of the second connector, it helps ensure the stability and consistency of the connection process, thus improving the accuracy of repeated operation when the shielding component switches between the first and second states multiple times.

[0070] Optionally, the guide member includes a first guide surface on the side facing the rotary cleaning member. Along the height direction of the cleaning equipment, one end of the first guide surface is a starting end and the other end is an extension end. The starting end is located above the extension end. The first guide surface gradually extends toward the rotary cleaning member along the direction from the starting end to the extension end. During the lowering process of the shielding member, the second connecting member can slide along the first guide surface to gradually approach the first connecting member, thereby achieving connection with the first connecting member.

[0071] The beneficial effects of this design are as follows: The first guide surface ensures that the second connector slides smoothly along a predetermined path during its descent, gradually approaching the first connector to achieve connection. This design reduces the probability of connection failure due to positional deviation of the second connector, thereby improving connection reliability. Simultaneously, because the first guide surface gradually extends towards the rotary cleaning component from the starting end to the extension end, it allows for a smooth transition in the movement of the second connector during descent, reducing impact or shaking caused by sudden positional changes. This smooth transition ensures the stability of the second connector's position as it approaches the first connector, thus facilitating rapid connection with the first connector.

[0072] Optionally, the guide member also includes a second guide surface on the side facing the rotary cleaning member. Along the height direction of the cleaning equipment, the second guide surface is disposed above the first guide surface and connected to the starting end. During the retraction of the shielding member, the second connecting member can slide along the second guide surface to guide the second connecting member, which has been separated from the first connecting member, to move with the shielding member to the retracted position.

[0073] The beneficial effects of this design are as follows: By setting a second guide surface, the probability of the second connector shifting during its movement after it separates from the first connector can be reduced. This can reduce problems such as jamming, abnormal noise, or component wear caused by deviation in the movement trajectory of the second connector during the retraction movement of the shielding component. It not only ensures the accuracy of the retraction position of the shielding component, but also helps to improve the service life of the parts.

[0074] Optionally, the guide member also includes a third guide surface on the side facing the rotary cleaning member. Along the height direction of the cleaning device, one end of the third guide surface is the first end, and the other end is the second end. The second end is located below the first end, and the first end is connected to the extension end. The third guide surface gradually extends away from the rotary cleaning member along the direction from the first end to the second end. During the retraction of the shielding member, the second connecting member can slide along the third guide surface to guide the second connecting member to slide onto the first guide surface.

[0075] The beneficial effects of this design are as follows: Because the distance between the extended end of the first guide surface and the rotary cleaning component is relatively short, the cross-section of the channel formed between them is narrow. Under these conditions, during the retraction of the shielding component, the second connecting component is prone to jamming when entering or exiting the channel, which in turn affects the smoothness of its passage. In this embodiment, by providing a third guide surface, the operating posture of the moving second connecting component can be adjusted before it enters the channel, allowing it to pass through the channel more smoothly. This further improves the smoothness of the second connecting component's operation during the retraction of the shielding component.

[0076] Optionally, one of the first connector and the second connector is provided with a slot portion, and the other is provided with a hook portion; when the slot portion and the hook portion are engaged, the first connector and the second connector are in a connected state; when the slot portion and the hook portion are disengaged, the first connector and the second connector are in a disengaged state.

[0077] The beneficial effects of this design are as follows: By incorporating the slot and hook portions, the connection and disengagement of the first and second connectors are achieved. Since the hook and slot portions form a mechanical interlocking connection, once engaged, they are less likely to loosen due to vibrations or accidental collisions during the operation of the cleaning equipment, thus ensuring the stability of the connection between the first and second connectors.

[0078] Optionally, at least a portion of the first connector is composed of a magnet, and at least a portion of the second connector is composed of a magnet or a magnetic attractor; or, at least a portion of the second connector is composed of a magnet, and at least a portion of the first connector is composed of a magnet or a magnetic attractor; when the magnet and the magnetic attractor are attracted together, or when the magnets are attracted together, the first connector and the second connector are in a connected state; when the magnet and the magnetic attractor are separated, or when the magnets are separated, the first connector and the second connector are in a separated state.

[0079] The beneficial effects of this design are as follows: at least a portion of the first connector is composed of a magnet, and at least a portion of the second connector is composed of a magnet or a magnetic attractor. This design allows the first and second connectors to be connected via magnetic attraction. When the magnet and the magnetic attractor (or another magnet) enter the effective magnetic field range, the magnetic force will actively attract them, thereby automatically correcting any positional deviations when they approach each other. This reduces the probability of connection failure due to large positional deviations between the first and second connectors. Furthermore, because the magnets and magnetic attractors can be designed with a small shape or volume, this connection structure is more suitable for space-constrained installation environments, contributing to a more compact overall structure for the cleaning equipment.

[0080] Optionally, the first connector has a first adhesive portion on the side corresponding to the second connector, and the second connector has a second adhesive portion on the side corresponding to the first connector; when the first adhesive portion and the second adhesive portion are bonded together, the first connector and the second connector are in a connected state; when the first adhesive portion and the second adhesive portion are separated, the first connector and the second connector are in a separated state.

[0081] The advantages of this design are as follows: Since the first and second adhesive portions are bonded together, the connection between the first and second connectors can be achieved without the need for complex mechanical interlocking components such as hooks or slots. Furthermore, both the first and second adhesive portions can be obtained from readily available, conventional adhesive components, eliminating the need for additional complex manufacturing processes and thus reducing production costs. Simultaneously, the adhesive connection itself does not significantly increase the thickness at the connection point, which facilitates a compact design for the cleaning equipment.

[0082] Optionally, the blocking mechanism further includes a drive assembly and a reel. The reel is rotatably mounted on the frame, and the drive assembly is mounted on the frame and has a rotating output end connected to the reel. One end of the blocking member is wound onto the reel, and the other end is a free end. A second connecting member is mounted on the free end. The drive assembly is used to drive the reel to rotate, so as to realize the opening and closing of the blocking member.

[0083] The advantages of this design are as follows: By setting up a drive component and a reel, the drive component can rotate the reel, thereby achieving automatic deployment and retraction of the shielding component. This structure enables fully automated deployment and retraction of the shielding component, improving ease of operation, reducing manual intervention, and enhancing the user experience. Furthermore, the retractable design saves internal installation space occupied by the retracted shielding component, thus facilitating optimized rack space layout.

[0084] Optionally, the shielding mechanism also includes a cover mounted on the frame, the cover having a storage cavity in which the shielding element is wound and stored.

[0085] The beneficial effects of this design are as follows: By installing a protective cover and housing the shielding component within its storage cavity, the cover effectively prevents dust, moisture, and other impurities from entering the storage cavity. This protects the shielding component from contamination and damage, thus extending its service life. Simultaneously, the cover provides physical protection for the shielding component, reducing the probability of damage caused by accidental impacts during the operation or maintenance of the cleaning equipment.

[0086] Optionally, a first card interface is provided on the side of the frame facing the cover, and a second card interface is provided on the side of the cover facing the frame. The first card interface and the second card interface are connected to each other and form a support hole for supporting the scroll. The scroll is rotatably installed in the support hole.

[0087] The advantages of this design are as follows: By interlocking the first and second locking interfaces on the frame and cover, support holes for supporting the reel are formed. During assembly, this design only requires aligning and fastening the frame and cover to automatically create the complete support hole, eliminating the need for additional independent bearing seats or brackets. This simplifies the assembly process, reduces complexity, and improves production efficiency. Furthermore, when reel replacement or maintenance is required, simply separating the cover from the frame causes the first and second locking interfaces to detach, opening the support hole and allowing the reel to be easily removed. The entire operation requires no special tools or laborious disassembly from the complex internal structure, thus reducing the difficulty of later maintenance.

[0088] Optionally, along the height direction of the cleaning equipment, the cover includes an extension extending toward the side of the rotary cleaning component, and a guide channel communicating with the storage cavity is formed between the extension and the frame, with the free end extending to the outside of the storage cavity via the guide channel.

[0089] The beneficial effects of this design are as follows: By establishing a guide channel connected to the storage cavity, and allowing the free end of the shielding component to extend outside the storage cavity through this channel, the guide channel can guide the shielding component during its retraction and deployment. Specifically, the guide channel can effectively guide the shielding component in and out of the storage cavity, reducing instability such as lateral swaying and vertical shaking during operation, thereby helping to ensure the accuracy and reliability of the shielding component's retraction and deployment.

[0090] Optionally, the free end and / or the second connector can abut against the extension to stop the free end and the second connector outside the receiving cavity when the shield retracts.

[0091] The advantages of this design are as follows: Since the free end and / or the second connector can abut against the extension, the free end and the second connector can be stably stopped outside the receiving cavity when the shielding member retracts. This design provides a constant pulling force to the shielding member in the retracted state, thus preventing the shielding member wound on the spool from becoming loose and ensuring the retraction accuracy of the shielding member. Furthermore, this design also ensures the repeatability of the shielding member's positioning accuracy each time it retracts, thereby improving the switching accuracy and efficiency between the first and second states.

[0092] Optionally, a guide arc surface is provided on the side of the frame near the second connector, and the second connector is provided with a mating surface. After the first connector and the second connector are separated, the guide arc surface and the mating surface cooperate with each other to guide the second connector to run along the contraction direction of the shield to the position where it abuts against the extension.

[0093] The beneficial effects of this design are as follows: Since the second connector is in a free or semi-free state after detaching from the first connector, it is prone to wobbling or shifting during movement, thus affecting the positional accuracy of its contact with the extension. Therefore, this embodiment provides a guide arc surface on the side of the frame near the second connector and a mating surface on the second connector. When the first connector detaches from the second connector, the guide arc surface and the mating surface cooperate to guide the second connector to move along the contraction direction of the blocking member to the position where it contacts the extension. This cooperation method effectively constrains the movement trajectory of the second connector, ensuring it runs precisely along a preset path and ultimately reaches the predetermined position where it contacts the extension, thereby improving the contact accuracy between the second connector and the extension.

[0094] Optionally, the drive assembly includes a drive element and a transmission assembly. The drive element is mounted on the cover and / or frame and has a rotary drive end. The power input end of the transmission assembly is connected to the rotary drive end, and the power output end of the transmission assembly forms a rotary output end.

[0095] The advantages of this design are as follows: By combining the drive component with the transmission assembly, different transmission types can be flexibly selected as needed. This design effectively adjusts the output speed and torque of the drive component, thereby more precisely matching the driving torque and operating speed required by the blocking component during its extension and retraction. This not only ensures the smoothness and power of the blocking component's operation but also better meets the specific requirements for drive performance under different working conditions.

[0096] Optionally, the rotation axis of the rotary drive end is parallel to the horizontal direction, so that the drive component is placed horizontally on the frame.

[0097] The advantages of this arrangement are: by placing the drive components laterally on the frame, the space they occupy in the height direction of the frame can be effectively reduced. This arrangement helps to reduce the overall height of the cleaning equipment, thus making it easier to achieve a slimmer and lighter design.

[0098] Optionally, along the height direction of the cleaning equipment, the side of the cover opposite to the rotary cleaning component has a receiving groove, and the drive component is at least partially located in the receiving groove.

[0099] The benefits of this design are: by setting up a receiving slot and placing at least part of the drive component inside the slot, the space occupied by the drive component above the mounting base can be effectively reduced, thereby reducing the overall design height of the cleaning equipment and facilitating the thinner and lighter design of the cleaning equipment.

[0100] Optionally, a bracket is connected to the cover, and a mounting cavity is formed between the bracket and the cover. The drive component is housed in the mounting cavity, and the rotary drive end extends to the outside of the mounting cavity and is connected to the power input end of the transmission assembly.

[0101] The beneficial effects of this design are as follows: By setting up a bracket and having the bracket cooperate with the protective cover to form a mounting cavity, the drive component can be placed inside the mounting cavity. This not only reduces the probability of external dust, liquids and other impurities coming into direct contact with the drive component, but also provides mechanical protection for the drive component, reducing the risk of damage to the drive component due to external collisions or interference.

[0102] Optionally, a first connecting part is provided on the side of the cover facing the bracket, and a second connecting part is provided on the side of the bracket facing the cover. The first connecting part and the second connecting part are snapped together and fixed, and together form a through hole for the rotary drive end to extend out.

[0103] The advantages of this design are as follows: By setting up interlocking first and second connecting parts that together form a through hole for the rotary drive end to extend, this design improves the positioning efficiency between the bracket and the cover through the interlocking structure of the first and second connecting parts, thus contributing to improved assembly efficiency. Furthermore, when the drive component needs to be disassembled, only the bracket needs to be removed and the connection between the drive component and the cover disconnected; the drive component can then be directly removed along the height of the cleaning equipment without requiring horizontal movement. This feature helps reduce the horizontal dimensions of the mounting cavity, thereby contributing to a reduction in the overall design dimensions of the bracket. Attached Figure Description

[0142] 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.

[0143] 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.

[0144] 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.

[0145] Please refer to Figures 1 to 33. This invention provides a cleaning device equipped with a shielding member 31. The linkage between the shielding member 31 and the rotary cleaning member 20 can be controlled by connecting and disconnecting the first connecting member 21 and the second connecting member 311. When the first connecting member 21 and the second connecting member 311 are connected, the rotary cleaning member 20 can drive the shielding member 31 to switch from a first state to a second state, thereby shielding the side of the rotary cleaning member 20 facing the surface to be cleaned. When the first connecting member 21 and the second connecting member 311 are disconnected, the linkage between the rotary cleaning member 20 and the shielding member 31 is released, the shielding member 31 is in the first state, and the side of the rotary cleaning member 20 facing the surface to be cleaned is exposed, allowing the rotary cleaning member 20 to perform cleaning operations normally. With this configuration, during the operation of the cleaning equipment, when the rotary cleaning component 20 passes over a specific obstacle, the connection between the first connecting component 21 and the second connecting component 311 enables the rotary cleaning component 20 and the blocking component 31 to work together. This allows the blocking component 31 to block the side of the rotary cleaning component 20 facing the surface to be cleaned, thereby isolating the rotary cleaning component 20 from the ground. Therefore, the probability of wastewater being blown onto the ground and causing contamination of the passage area when the wet rotary cleaning component 20 passes over a specific obstacle can be reduced. In particular, it can reduce the probability of wastewater dripping onto carpets when the wet rotary cleaning component 20 passes over carpets, as well as the probability of long fibers on the carpet coming into contact with the rotary cleaning component 20, thus reducing the risk of carpet contamination.

[0146] Please refer to Figures 1 to 4. The cleaning device includes: a frame 10, a rotary cleaning component 20, an internal support mechanism 40, and a shielding component 31. This cleaning device can be any self-propelled mopping device, such as a floor scrubber, sweeper, or cleaning robot. For ease of description, this application uses a cleaning robot as an example.

[0147] The frame 10 has internal storage space to accommodate various components of the cleaning equipment. The frame 10 can be of any shape, such as circular, elliptical, or D-shaped. The cleaning equipment also includes a drive system conventionally found on existing cleaning equipment. This drive system is located below the frame 10 to enable the cleaning equipment to move independently. The specific structure of the drive system and the connection between the drive system and the frame 10 can be found in descriptions of relevant structures in existing cleaning equipment and will not be repeated here.

[0148] An inner support mechanism 40 is mounted on the frame 10, and a rotary cleaning component 20 is fitted around the outer periphery of the inner support mechanism 40. The inner support mechanism 40 drives the rotary cleaning component 20 to rotate, thereby performing the cleaning operation. The inner support mechanism 40 can be formed using different support structures such as roller type or track type, as long as it can drive the rotary cleaning component 20 to rotate for cleaning operations. Specifically, if the inner support mechanism 40 is a roller type structure, then the rotary cleaning component 20 fitted around the outer periphery of the inner support mechanism 40 can form a roller type wiping cloth structure. If the inner support mechanism 40 is a track type support structure, then the rotary cleaning component 20 fitted around the outer periphery of the inner support mechanism 40 can form a track type wiping cloth structure.

[0149] Optionally, in this embodiment, as shown in Figure 2, the inner support mechanism 40 is a tracked support structure, and the rotary cleaning component 20 is sleeved on the outer periphery of the tracked support structure to form a tracked rag structure. The specific structure of the tracked support mechanism is not limited. For example, in one embodiment, the tracked support mechanism includes a motor and two support rollers interconnected by a bracket. The two support rollers are rotatably connected to the bracket, and the motor drives one of the support rollers to rotate. The rotary cleaning component 20 is sleeved on the outer periphery of the two support rollers. The motor's operation drives the support rollers to rotate, thereby driving the rotary cleaning component 20 to rotate. Of course, in other embodiments, the tracked support mechanism can also be other existing structures, and this embodiment does not limit this.

[0150] It should be noted that the internal support mechanism 40 can be directly installed on the frame 10, or it can be indirectly connected to the frame 10 through other structural components connected to the frame 10.

[0151] Optionally, referring to Figures 2 and 3, in one embodiment, the frame 10 may also be equipped with a mounting base 50 and a moving mechanism 60. An inner support mechanism 40 is connected to the mounting base 50, and the mounting base 50 is connected to the frame 10 via the moving mechanism 60, thereby achieving the connection between the inner support mechanism 40 and the frame 10. In one embodiment, the moving mechanism 60 can drive the mounting base 50 to move up and down relative to the frame 10, thereby causing the rotary cleaning component 20 to move between a raised position and a lowered position relative to the frame 10. In another embodiment, the moving mechanism 60 can also drive the mounting base 50 to extend and retract horizontally relative to the frame 10, thereby causing the rotary cleaning component 20 to move between a retracted position and an outward swing position. In other embodiments, the moving mechanism 60 can both drive the mounting base 50 to extend and retract horizontally relative to the frame 10 and drive the mounting base 50 to move up and down relative to the frame 10, meaning the rotary cleaning component 20 can move between the raised and lowered positions, and also between the retracted and outward swing positions.

[0152] In this embodiment, the structure of the moving mechanism 60 is not limited, and includes, but is not limited to, linkage mechanisms, linear actuators, pulley lifting assemblies, etc. The specific connection structure between the moving mechanism 60 and the frame 10 and mounting base 50 can be referred to the relevant structural descriptions in existing cleaning equipment, and will not be repeated here.

[0153] Referring to Figures 2 and 4, the shielding mechanism 30 includes a shielding member 31, which is retractably mounted on the frame 10. Specifically, the shielding member 31 is retractably mounted on the mounting base 50. Of course, in other embodiments, the shielding member 31 can also be retractably mounted on the frame 10. The shielding member 31 has a first state and a second state. As shown in Figure 2, in the first state, the shielding member 31 is in a retracted state, so that the side of the rotary cleaning member 20 facing the surface to be cleaned is exposed, allowing the rotary cleaning member 20 to perform normal cleaning operations. As shown in Figure 7, in the second state, the shielding member 31 is in a lowered and extended state, and can shield the side of the rotary cleaning member 20 facing the surface to be cleaned, thereby isolating the rotary cleaning member 20 from the surface to be cleaned. It is understood that in this embodiment, when the shielding member 31 switches between the first state and the second state, the rotary cleaning member 20 can be in any position, such as a raised position, a lowered position, an inward position, or an outward swing position.

[0154] In this embodiment, the retraction and unfolding method of the blocking member 31 is not limited. For example, in one embodiment, the blocking mechanism 30 may also include a roller and a drive assembly. The roller is rotatably mounted on the mounting base 50, and the drive assembly is used to drive the roller to rotate. The blocking member 31 is wound around the roller to form a roller shutter structure. The retraction and unfolding of the blocking member 31 can be achieved by driving the rotation of the roller through the drive assembly. In other embodiments, the blocking mechanism 30 may also include a sliding mechanism, which is slidably mounted on the mounting base 50. The blocking member 31 is made of a flexible material (such as canvas). One end of the blocking member 31 is fixed to the mounting base 50, and the other end is connected to the sliding mechanism. Driven by the sliding mechanism, the blocking member 31 can be kept flat and retracted inside the frame 10, or it can slide out of the frame 10 as a whole to be unfolded.

[0155] Please refer to Figures 5 and 6. The rotary cleaning component 20 includes a first connecting member 21 that moves in tandem with the rotary cleaning component 20, and the shielding component 31 includes a second connecting member 311. The first connecting member 21 and the second connecting member 311 can be in a connected state (as shown in Figure 6) and a disconnected state (as shown in Figure 5). The first connecting member 21 can be directly fixedly connected to the rotary cleaning component 20, or it can be indirectly fixedly connected to the rotary cleaning component 20 through other structural components, as long as it can achieve linkage with the rotary cleaning component 20. It should be noted that, in this embodiment, the linkage of the first connecting member 21 with the rotary cleaning component 20 specifically means that the first connecting member 21 can rotate synchronously with the rotary cleaning component 20 during its rotation.

[0156] In the connected state, the shielding member 31 is linked to the rotary cleaning member 20, meaning that the rotation of the rotary cleaning member 20 can drive the shielding member 31 to move synchronously, thereby enabling the shielding member 31 to switch between the first and second states. In the disengaged state, the first connecting member 21 is disengaged from the second connecting member 311, thereby releasing the linkage between the shielding member 31 and the rotary cleaning member 20, allowing the rotary cleaning member 20 and the shielding member 31 to operate independently.

[0157] Specifically, when the shielding member 31 needs to switch from the first state to the second state, the first connecting member 21 and the second connecting member 311 are connected to each other, forming a connected state. During the operation of the rotary cleaning member 20, the rotation of the rotary cleaning member 20 causes the shielding member 31 to gradually lower and unfold until it completely covers the side of the rotary cleaning member 20 facing the surface to be cleaned. At this time, the rotary cleaning member 20 stops operating. When the shielding member 31 needs to switch from the second state to the first state, the rotary cleaning member 20 operates in the opposite direction, and the shielding member 31 gradually retracts until the side of the rotary cleaning member 20 facing the surface to be cleaned is completely exposed. At this time, the first connecting member 21 and the second connecting member 311 disengage, and the rotary cleaning member 20 can resume normal operation, preparing for normal cleaning work. It should be noted that when the shielding member 31 is in the first state, the first connecting member 21 and the second connecting member 311 are in a disengaged state. When the shielding member 31 is in the second state, the first connecting member 21 and the second connecting member 311 are in a connected state.

[0158] In this embodiment, the connection between the first connector 21 and the second connector 311 is not limited. For example, it can be connected by a hook and a slot engaging with each other, or by magnetic attraction between a magnet and a magnetic attractant. It should be noted that the first connector 21 and the second connector 311 can be connected and separated manually, or they can be automatically connected and separated by the change in the relative running posture of the rotary cleaning component 20 and the shielding component 31 during operation.

[0159] In this embodiment, the cleaning equipment is equipped with a shielding member 31, and the linkage between the shielding member 31 and the rotary cleaning member 20 can be controlled by connecting and disconnecting the first connecting member 21 and the second connecting member 311. When the first connecting member 21 and the second connecting member 311 are connected, the rotary cleaning member 20 can drive the shielding member 31 to switch from a first state to a second state, thereby shielding the side of the rotary cleaning member 20 facing the surface to be cleaned. When it is disconnected, the linkage between the rotary cleaning member 20 and the shielding member 31 is released, the shielding member 31 is in the first state, and the side of the rotary cleaning member 20 facing the surface to be cleaned is exposed, so that the rotary cleaning member 20 can perform normal cleaning operations. With this configuration, on the one hand, during the operation of the cleaning equipment, when the rotary cleaning member 20 passes through a specific obstacle, the shielding member 31 can be in the second state to shield the side of the rotary cleaning member 20 facing the surface to be cleaned, thereby isolating the rotary cleaning member 20 from the ground. Therefore, the probability of wastewater being blown onto the ground and causing contamination of the passage area when the rotating cleaning unit 20 in a wet state passes over certain obstacles can be reduced. In particular, it can reduce the probability of wastewater dripping onto carpets when the rotating cleaning unit 20 in a wet state, as well as the probability of long fibers on the carpet coming into contact with the rotating cleaning unit 20, thereby reducing the risk of carpet contamination. At the same time, when the cleaning equipment passes through other areas that are not suitable for wet cleaning (such as cleaned areas, areas under furniture, or wooden floors that need to be kept dry), the above structure can also reduce the probability of wastewater dripping into such areas, thereby reducing the possibility of contamination.

[0160] On the other hand, by controlling the connection and disconnection of the first connector 21 and the second connector 311, the shielding member 31 and the rotary cleaning member 20 can be linked, enabling them to automatically switch between the first and second states. Therefore, based on this linkage mechanism, an automatic pulling end can be formed at one end of the shielding member 31, eliminating the need for additional pulling or pushing mechanisms, thus simplifying the structural design of the cleaning equipment and reducing production costs.

[0161] Referring to Figures 6 and 7, in one embodiment of the present invention, the rotary cleaning component 20 has a first rotation direction and a second rotation direction, which are opposite to each other. When the shielding component 31 switches from the first state to the second state, the rotary cleaning component 20 rotates along the first rotation direction; when the shielding component 31 switches from the second state to the first state, the rotary cleaning component 20 rotates along the second rotation direction. Since the switching between the first and second states of the shielding component 31 can be achieved by controlling the rotation direction of the rotary cleaning component 20, this method simplifies the control logic of the shielding component 31's operation, eliminating the need for operators or control systems to handle complex turning actions. This reduces the operational difficulty and error probability of switching the shielding component 31 between different states, thereby improving the ease of use and reliability of the cleaning equipment.

[0162] There are several ways to switch the shielding member 31 from the first state to the second state. For example, in one embodiment, the shielding mechanism 30 is provided with a second drive source (such as a motor or hydraulic motor). When the shielding member 31 needs to switch from the first state to the second state, the second drive source is controlled to operate, driving the shielding member 31 to gradually lower. At the same time, the inner support mechanism 40 is provided with a first drive source (such as a motor or hydraulic motor). The first drive source rotates forward, driving the rotary cleaning member 20 to rotate along the first rotation direction. The rotation of the rotary cleaning member 20 pulls the shielding member 31 to achieve the lowering action, realizing the switching of the shielding member 31 from the first state to the second state.

[0163] In another embodiment, when the shielding member 31 needs to switch from the first state to the second state, the first drive source of the inner support mechanism 40 rotates clockwise, driving the rotary cleaning member 20 to rotate along the first rotation direction, and the rotation of the rotary cleaning member 20 pulls the shielding member 31 down gradually. At this time, the second drive source on the shielding mechanism 30 is in a stopped operation mode, and the switching of the shielding member 31 from the first state to the second state is achieved solely by the pulling of the rotary cleaning member 20.

[0164] Similarly, there are multiple ways to achieve the switching of the shielding member 31 from the second state to the first state. For example, in one embodiment, when the shielding member 31 needs to switch from the second state to the first state, the second drive source of the shielding mechanism 30 is controlled to operate, causing the shielding member 31 to gradually retract. At the same time, the first drive source of the inner support mechanism 40 drives the rotary cleaning member 20 to rotate along the second rotation direction, which cooperates with the retraction action of the shielding member 31 to jointly realize the switching of the shielding member 31 from the second state to the first state.

[0165] In another embodiment, when the shielding member 31 needs to switch from the second state to the first state, only the second drive source of the shielding mechanism 30 is controlled to operate, driving the shielding member 31 to gradually retract. The first drive source of the inner support mechanism 40 is in a stopped operation mode. Only the retraction pulling action of the second drive source on the shielding member 31 drives the rotary cleaning member 20 to rotate in the second rotation direction, so as to realize the switching of the shielding member 31 from the second state to the first state.

[0166] It should be noted that in this embodiment, the second rotation direction is the cleaning direction of the rotary cleaning component 20 (as shown in direction N1 in Figure 6), that is, the rotation direction of the rotary cleaning component 20 when performing wet cleaning operations, and the first rotation direction is the non-cleaning direction opposite to the cleaning direction. Since the rotary cleaning component 20 can only perform cleaning tasks in the exposed state, setting the second rotation direction as the cleaning direction of the rotary cleaning component 20 means that when the shielding component 31 switches from the second state to the first state, the rotary cleaning component 20 does not need to change its rotation direction, that is, it can continue to rotate along the second rotation direction to perform cleaning tasks, thus reducing unnecessary turning actions. This not only simplifies the control logic of the cleaning equipment's operation, but also helps to improve the cleaning efficiency of the cleaning equipment. Of course, if the above-mentioned beneficial effects are not considered, in other embodiments, the first rotation direction can also be the cleaning direction of the rotary cleaning component 20, and the second rotation direction can be the non-cleaning direction opposite to the cleaning direction.

[0167] In one embodiment of the present invention, the rotary cleaning component 20 includes a first arcuate segment 201, a second arcuate segment 202, a first planar segment 203, and a second planar segment 204. The first arcuate segment 201 and the second arcuate segment 202 are distributed horizontally and along the forward direction of the cleaning device (as shown by the X-axis in FIG6). The first arcuate segment 201 is closer to the front end of the cleaning device, and the second arcuate segment 202 is closer to the rear end of the cleaning device. The first planar segment 203 connects between the first arcuate segment 201 and the second arcuate segment 202 and is disposed close to the surface to be cleaned. The second planar segment 204 connects between the first arcuate segment 201 and the second arcuate segment 202 and is located on the side of the first planar segment 203 away from the surface to be cleaned. The first planar segment 203 and the second planar segment 204 are parallel or substantially parallel. When the shielding member 31 switches from the first state to the second state, it sequentially passes through and shields the first arcuate segment 201, the first planar segment 203, and the second arcuate segment 202. When the shielding member 31 switches from the second state to the first state, it sequentially moves away from and exposes the second arcuate segment 202, the first planar segment 203, and the first arcuate segment 201. In this embodiment, the rotary cleaning member 20 is tensioned on the tracked support structure to form the aforementioned first arcuate segment 201, second arcuate segment 202, first planar segment 203, and second planar segment 204.

[0168] Specifically, referring to Figure 6, the mounting base 50 has a receiving cavity 501, and the rotary cleaning component 20 is installed in the receiving cavity 501. The shielding mechanism 30 is disposed outside the receiving cavity 501. Along the forward direction of the cleaning device, when the shielding component 31 is in the first state, the shielding component 31 is located at the front end of the rotary cleaning component 20 and is disposed near the first arcuate section 201.

[0169] Referring to Figure 6, when the blocking member 31 needs to switch from the first state to the second state, the second connecting member 311 on the blocking member 31 will connect with the first connecting member 21 on the rotary cleaning member 20 in the area near the first arc-shaped section 201. Then, during the rotation of the rotary cleaning member 20, the blocking member 31 will sequentially pass through and block the first arc-shaped section 201, the first flat section 203, and the second arc-shaped section 202. Referring to Figure 7, when the blocking member 31 is in the second state, the first connecting member 21 and the second connecting member 311, which are in the connected state, remain in the area near the second arc-shaped section 202. It should be noted that the blocking member 31 can block the entire second arc-shaped section 202, or it can only block a portion of the second arc-shaped section 202 near the first flat section 203. When the shielding member 31 switches from the second state to the first state, the rotary cleaning member 20 is linked with the shielding member 31 so that the shielding member 31 moves away from and exposes the second arc surface segment 202, the first flat surface segment 203 and the first arc surface segment 201 in sequence.

[0170] In this embodiment, when the shielding member 31 switches from the first state to the second state, it sequentially passes through and shields the first arc-shaped segment 201, the first flat segment 203, and the second arc-shaped segment 202. When the shielding member 31 switches from the second state to the first state, it sequentially moves away from and exposes the second arc-shaped segment 202, the first flat segment 203, and the first arc-shaped segment 201. This configuration has two advantages: First, in the first state, the shielding member 31 can completely expose the side of the rotating cleaning member 20 facing the surface to be cleaned. This means that during normal cleaning operations, the shielding member 31 will not interfere with the cleaning function of the rotating cleaning member 20, ensuring the efficiency and effectiveness of the cleaning operation. Second, in the second state, the shielding member 31 can have an arc-shaped structure on the outer periphery of the cleaning member near the second arc-shaped segment 202. This design allows wastewater dripping from the rotating cleaning member 20 to be effectively collected on the shielding member 31, thereby reducing the risk of wastewater leakage in the shielded state. In this way, the shielding member 31 can better isolate the rotating cleaning member 20 from the surface to be cleaned, thus improving the isolation effect.

[0171] Referring to Figures 8 and 9, in one embodiment of the present invention, the rotary cleaning component 20 includes a cleaning component body 205 and an annular portion 206. The cleaning component body 205 is used to clean the surface to be cleaned, and the annular portion 206 is disposed at the end of the cleaning component body 205. A first connecting member 21 is connected to the annular portion 206. Specifically, the outer periphery of the cleaning component body 205 may be provided with a water-absorbing layer, which contacts the surface to be cleaned, so as to achieve cleaning of the surface to be cleaned during the rotation of the rotary cleaning component 20.

[0172] When the second connector 311 is provided on one side of the shielding member 31 along its length, an annular portion 206 can be provided only at one end of the cleaning member body 205 along its length, and the first connector 21 is connected to the annular portion 206. Alternatively, annular portions 206 can be provided at both ends of the cleaning member body 205 along its length, and the first connector 21 can be provided only on the side corresponding to the second connector 311. When the second connector 311 is provided on both sides of the shielding member 31 along its length, annular portions 206 can be provided at both ends of the cleaning member body 205 along its length, and the first connector 21 can be provided on both ends of the annular portion 206 to cooperate and connect with the second connector 311 on the corresponding side.

[0173] In this embodiment, by providing an annular portion 206 at the end of the cleaning component body 205 and connecting the first connector 21 to the annular portion 206, this arrangement allows for flexible adjustment of the installation position of the first connector 21 relative to the cleaning component body 205 by adjusting the shape and size of the annular portion 206. This reduces the possibility of interference between the first connector 21 and the cleaning component body 205 in the height or width direction. Simultaneously, this design also helps reduce the occupation or impact of the first connector 21 on the effective cleaning surface of the cleaning component body 205, thereby optimizing the overall structural layout of the rotary cleaning component 20 and improving the compactness of the rotary cleaning component 20's structural design.

[0174] While ensuring the connection strength requirements between the annular portion 206 and the cleaning component body 205, there can be various connection methods between the annular portion 206 and the cleaning component body 205. Optionally, in one embodiment of the present invention, referring to Figure 9, the annular portion 206 and the cleaning component body 205 are fixedly connected, and the cleaning component body 205 drives the annular portion 206 to rotate synchronously during rotation. The fixed connection method can be an integral molding connection. Specifically, the cleaning component body 205 also includes a rubber layer, and an absorbent layer covers the outer periphery of the rubber layer. The annular portion 206 and the rubber layer are integrally injection molded and connected. The fixed connection method can also be a snap-fit ​​connection or a bolt connection, etc. In this embodiment, since the annular portion 206 and the cleaning component body 205 are fixedly connected, there will be no relative displacement between the two during the rotation of the rotary cleaning component 20, resulting in better motion synchronization and making it more conducive to ensuring the switching accuracy between the first connecting member 21 and the second connecting member 311 in the connected state and the disconnected state.

[0175] In another embodiment of the present invention, the annular portion 206 and the cleaning component body 205 are separately disposed, and the inner support mechanism 40 drives the cleaning component body 205 and the annular portion 206 to rotate synchronously. The annular portion 206 and the cleaning component body 205 can be in contact with each other or not in contact; this embodiment does not limit this and can be flexibly selected according to actual structural requirements. In this embodiment, since the annular portion 206 and the cleaning component body 205 adopt a separate design, they can be independently installed on the inner support mechanism 40. This structural design allows the annular portion 206 and the cleaning component body 205 to be operated independently when replacement is needed, without replacing the entire rotary cleaning component 20, thereby reducing maintenance difficulty and maintenance costs.

[0176] In one embodiment of the present invention, along the forward direction perpendicular to the cleaning device, i.e., the length direction of the rotary cleaning component 20 (as shown by the Y-axis in FIG10), the annular portion 206 protrudes from the cleaning component body 205. The length L2 of the blocking component 31 is greater than or equal to the length of the cleaning component body 205, and less than the maximum length L1 of the rotary cleaning component 20. It should be noted that, referring to FIG6 and FIG9, the projected outer contour of the annular portion 206 along the length direction of the rotary cleaning component 20 is located within the projected outer contour of the cleaning component body 205. Furthermore, the projected outer contours of the annular portion 206 and the first connecting component 21 are both located within the projected outer contour of the cleaning component body 205. This arrangement ensures that the arrangement of the annular portion 206 and the first connecting component 21 does not affect the effective cleaning area of ​​the cleaning component body 205. In this embodiment, the length direction of the blocking component 31 is consistent with the length direction of the cleaning component body 205. When annular portions 206 are provided at both ends of the cleaning component body 205, the maximum length of the rotary cleaning component 20 refers to the distance along the length direction of the cleaning component body 205 between the outer edges of the two annular portions 206 located at both ends of the cleaning component body 205, i.e., the dimension L1 marked in Figure 10. When annular portions 206 are provided at one end of the cleaning component body 205, the maximum length of the rotary cleaning component 20 refers to the distance along the length direction of the cleaning component body 205 between the outer edge of the side of the cleaning component body 205 where no annular portion 206 is provided and the outer edge of the annular portion 206.

[0177] In this embodiment, since the length of the shielding member 31 is greater than or equal to the length of the cleaning member body 205, and less than the maximum length of the rotary cleaning member 20, this arrangement ensures that, on the one hand, the shielding member 31 can fully cover the cleaning member body 205 when in the shielding state, effectively preventing sewage from dripping from the cleaning member body 205 onto the surface to be cleaned, thus ensuring the shielding effect of the shielding member 31. On the other hand, since the length of the shielding member 31 does not exceed the maximum range of the rotary cleaning member 20, it avoids occupying additional installation space in the length direction of the rotary cleaning member 20 due to the setting of the shielding member 31, which helps to ensure the compactness of the overall structure of the cleaning equipment. At the same time, it also provides clearance space for the connection or disconnection of the first connecting member 21 and the second connecting member 311.

[0178] Considering the stability of the shielding member 31 during operation when switching between the first and second states, optionally, referring to FIG10, in one embodiment of the present invention, the cleaning member body 205 includes a first end 2051 and a second end 2052 along the forward direction perpendicular to the cleaning device, and the shielding member 31 includes a first side 313 and a second side 314. At least one annular portion 206 is provided at the first end 2051 and the second end 2052, and at least one second connecting member 311 is provided at the first side 313 and the second side 314, respectively. To further optimize manufacturing costs and simplify the design structure, optionally, referring to FIGS8 and 9, in this embodiment, each of the first end 2051 and the second end 2052 of the cleaning member body 205 is provided with an annular portion 206, and each of the first side 313 and the second side 314 of the shielding member 31 is provided with a second connecting member 311. It should be noted that at least one first connecting member 21 is provided on the annular portion 206, and the first connecting member 21 can be connected to or disconnected from the second connecting member 311 on the corresponding side.

[0179] In this embodiment, since each end of the cleaning component body 205 has an annular portion 206, and both sides of the shielding component 31 have second connecting members 311, this arrangement allows for a connection between the first connecting member 21 and the second connecting member 311 on both sides of the shielding component 31. This configuration ensures that the connecting force is simultaneously and evenly transmitted from both sides to the cleaning component body 205. This double-sided connection design reduces localized stress concentration in the cleaning component body 205 caused by unilateral force application, ensuring uniform compression and thus guaranteeing the stability of the cleaning effect. Furthermore, this design effectively reduces problems such as twisting, displacement, or connection failure of the shielding component 31 due to uneven force application, thereby improving the operational stability of the shielding component 31.

[0180] In another embodiment of the present invention, at least one annular portion 206 is provided at the first end 2051 or the second end 2052, and at least one second connecting member 311 is provided on the first side 313 or the second side 314 corresponding to the annular portion 206. Compared with the scheme in which the annular portion 206 is provided on both sides of the cleaning component body 205, this embodiment adopts a single-sided configuration of the annular portion 206 and the second connecting member 311. This configuration, while ensuring the realization of basic functions, has the advantages of simplified structure, improved manufacturing and assembly efficiency, and reduced material costs. This design is particularly suitable for applications with strict limitations on installation space or manufacturing costs, and can provide greater flexibility for the overall layout of the cleaning equipment while maintaining the operational stability of the shielding member 31 and the uniformity of the compression of the cleaning component.

[0181] Referring to Figures 7 to 9, in one embodiment of the present invention, multiple first connectors 21 are provided on the annular portion 206. These multiple first connectors 21 are spaced apart along the outer periphery of the annular portion 206, and each first connector 21 can be connected to or disconnected from a second connector 311. The multiple first connectors 21 can be arranged at equal intervals or at unequal intervals along the outer periphery of the annular portion 206. Optionally, in this embodiment, the multiple first connectors 21 are arranged at equal intervals along the outer periphery of the annular portion 206. This arrangement not only facilitates the forming and positioning of the multiple first connectors 21 on the annular portion 206 but also improves assembly consistency.

[0182] Compared to the previous design where a single first connector 21 was provided on the annular portion 206, this embodiment uses multiple first connectors 21 arranged along the outer periphery of the annular portion 206. When a first connector 21 needs to mate with a second connector 311, the rotary cleaning component 20 only needs to be rotated by a small angle to allow one of the first connectors 21 to quickly approach and reliably connect with the second connector 311. Therefore, this layout improves the efficiency of the shielding component 31 switching between the first and second states, enhancing operational convenience and response speed.

[0183] Referring to Figures 13 and 14, in one embodiment of the present invention, the cleaning device further includes a guide member 12. The guide member 12 is disposed on the frame 10, which includes a mounting base 50. Therefore, the guide member 12 can be disposed at other locations on the frame 10 besides the mounting base 50, or it can be disposed on the mounting base 50. The guide member 12 is located on the outer periphery of the rotary cleaning member 20. Specifically, the guide member 12 is disposed on the outer periphery of the annular portion 206 and is disposed close to the first arcuate segment 201 in the circumferential direction of the rotary cleaning member 20. The guide member 12 can be integrally formed and connected to the frame 10, or it can be fixedly connected by fasteners such as bolts. The guide member 12 is used to guide the second connecting member 311 close to the rotary cleaning member 20 during the lowering of the shielding member 31, so as to achieve connection with the first connecting member 21 during the rotation of the rotary cleaning member 20. The specific structural form of the guide member 12 can be selected according to actual needs. For example, the guide member 12 can be any structure such as a groove or a protrusion that can guide the movement of the second connecting member 311 during the lowering of the shielding member 31, so that it can approach and connect to the first connecting member 21.

[0184] In this embodiment, by providing the guide member 12, the second connecting member 311 can be guided close to the rotary cleaning member 20 during the lowering of the shielding member 31, thereby ensuring that the second connecting member 311 can accurately connect with the first connecting member 21. Since the guide member 12 can constrain and guide the movement path of the second connecting member 311 during the lowering of the shielding member 31, the probability of connection failure due to deviation in the movement position of the second connecting member 311 is reduced, thus improving the reliability of the connection between the first connecting member 21 and the second connecting member 311. Simultaneously, since the guide member 12 can reduce the positional error of the second connecting member 311 during movement, it helps ensure the stability and consistency of the connection process, thereby improving the repeatability accuracy of the shielding member 31 when switching between the first and second states multiple times.

[0185] Referring to Figure 14, in one embodiment of the present invention, the guide member 12 includes a first guide surface 121 on the side facing the rotary cleaning member 20. Along the height direction of the cleaning device, one end of the first guide surface 121 is a starting end 1211, and the other end is an extension end 1212. The starting end 1211 is located above the extension end 1212, and the first guide surface 121 gradually extends toward the rotary cleaning member 20 along the direction from the starting end 1211 to the extension end 1212. During the lowering process of the shielding member 31, the second connecting member 311 can slide along the first guide surface 121 to gradually approach the first connecting member 21, thereby achieving connection with the first connecting member 21.

[0186] The specific structural form of the first guide surface 121 is not limited; for example, it can be a sloped structure, an arc-shaped structure, etc. The key is to guide the second connecting member 311 to gradually approach the first connecting member 21 during the lowering of the shielding member 31, thereby achieving connection with the first connecting member 21. Optionally, in this embodiment, the first guide surface 121 is a sloped structure. The upper end of the sloped structure forms a starting end 1211, and the lower end forms an extension end 1212. The sloped structure gradually extends obliquely towards the rotary cleaning member 20 from the starting end 1211 to the extension end 1212.

[0187] In this embodiment, the first guide surface 121 ensures that the second connector 311 slides smoothly along a predetermined path during its downward movement and gradually approaches the first connector 21 to achieve connection. This design reduces the probability of connection failure due to positional deviation of the second connector 311, thereby improving connection reliability. Simultaneously, since the first guide surface 121 gradually extends towards the rotary cleaning component 20 from the starting end 1211 to the extension end 1212, the second connector 311 achieves a smooth transition in its position during lowering, thus reducing impact or shaking caused by sudden positional changes. This smooth transition ensures the stability of the second connector 311's position as it approaches the first connector 21, and facilitates rapid connection with the first connector 21.

[0188] Referring to Figure 14, in one embodiment of the present invention, the guide member 12 further includes a second guide surface 122 on the side facing the rotary cleaning member 20. Along the height direction of the cleaning device, the second guide surface 122 is disposed above the first guide surface 121 and connected to the starting end 1211. During the retraction of the shielding member 31, the second connecting member 311 can slide along the second guide surface 122 to guide the second connecting member 311, after detaching from the first connecting member 21, to move with the shielding member 31 to the retracted position. By providing the second guide surface 122, the probability of the second connecting member 311 deviating during its movement after detaching from the first connecting member 21 can be reduced. This reduces problems such as jamming, abnormal noise, or component wear caused by deviation in the movement trajectory of the second connecting member 311 during the retraction movement of the shielding member 31. This not only ensures the accuracy of the retraction position of the shielding member 31 but also helps to improve the service life of the parts.

[0189] Referring to Figure 14, in one embodiment of the present invention, the guide member 12 further includes a third guide surface 123 on the side facing the rotary cleaning member 20. Along the height direction of the cleaning device, one end of the third guide surface 123 is a first end 1231, and the other end is a second end 1232. The second end 1232 is disposed below the first end 1231, and the first end 1231 is connected to the extension end 1212. The third guide surface 123 gradually extends away from the rotary cleaning member 20 along the direction from the first end 1231 to the second end 1232. During the retraction of the blocking member 31, the second connecting member 311 can slide along the third guide surface 123 to guide the second connecting member 311 to slide onto the first guide surface 121. Because the distance between the extension end 1212 of the first guide surface 121 and the rotary cleaning member 20 is relatively short, the cross-section of the channel formed between them is narrow. Under these conditions, during the retraction of the blocking member 31, the second connecting member 311 may experience jamming or other problems when entering or exiting the channel, which will affect the smoothness of its passage. In this embodiment, by providing a third guide surface 123, the operating posture of the moving second connecting member 311 can be adjusted before it enters the channel, allowing it to pass through the channel more smoothly. This further improves the smoothness of the second connecting member 311's operation during the retraction of the blocking member 31.

[0190] Referring to Figures 6 and 7, in one embodiment of the present invention, one of the first connecting member 21 and the second connecting member 311 is provided with a slot portion 3111, and the other is provided with a hook portion 211. When the slot portion 3111 and the hook portion 211 are engaged, the first connecting member 21 and the second connecting member 311 are in a connected state; when the slot portion 3111 and the hook portion 211 are disengaged, the first connecting member 21 and the second connecting member 311 are in a disengaged state. Specifically, in this embodiment, the first connecting member 21 is provided with a hook portion 211, and the second connecting member 311 is provided with a slot portion 3111. Of course, in another embodiment, the second connecting member 311 may also be provided with a hook portion 211, and the first connecting member 21 may be provided with a slot portion 3111. The specific structural shape of the hook portion 211 is not limited, for example, it may be a wedge-shaped hook, an L-shaped hook, or a single ratchet tooth, etc. The shape of the slot portion 3111 matches the shape of the hook portion 211, and the specific shape needs to be determined according to the shape of the hook portion 211.

[0191] In this embodiment, the connection and disconnection of the first connector 21 and the second connector 311 are achieved by providing the slot portion 3111 and the hook portion 211. Since the hook portion 211 and the slot portion 3111 can form a mechanical interlocking connection, once the interlocking connection is established, they are not easily loosened due to vibration or accidental collision during the operation of the cleaning equipment. Therefore, the stability of the connection state between the first connector 21 and the second connector 311 can be ensured.

[0192] In this embodiment, the specific process of the slot portion 3111 and the hook portion 211 engaging or disengaging with each other is as follows: When it is necessary to connect the first connecting member 21 and the second connecting member 311, the blocking member 31 is gradually lowered. As the blocking member 31 moves down, the second connecting member 311 also gradually approaches the first connecting member 21. During the rotation of the rotary cleaning member 20, the hook portion 211 and the slot portion 3111 engage with each other, thereby connecting the first connecting member 21 and the second connecting member 311. This connection allows the blocking member 31 to switch from the first state to the second state when the rotary cleaning member 20 rotates. When the blocking member 31 needs to switch back from the second state to the first state, the rotary cleaning member 20 rotates in the opposite direction. At this time, the hook portion 211 and the slot portion 3111 remain engaged with each other to achieve the retraction of the blocking member 31. When the blocking member 31 moves to a position close to its retracted position, it stretches in a direction approximately tangential to the rotary cleaning member 20, while the rotary cleaning member 20 continues to rotate in the opposite direction. This causes the hook portion 211 and the slot portion 3111 to move away from each other. During this movement, the hook portion 211 gradually disengages from the slot portion 3111, thereby achieving the disengagement of the first connecting member 21 from the second connecting member 311.

[0193] In one embodiment of the present invention, at least a portion of the first connector 21 is composed of a magnet, and at least a portion of the second connector 311 is composed of a magnet or a magnetic attractor; or, at least a portion of the second connector 311 is composed of a magnet, and at least a portion of the first connector 21 is composed of a magnet or a magnetic attractor; when the magnet and the magnetic attractor are attracted together, or when the magnets are attracted together, the first connector 21 and the second connector 311 are in a connected state; when the magnet and the magnetic attractor are separated, or when the magnets are separated, the first connector 21 and the second connector 311 are in a separated state.

[0194] Specifically, in one embodiment, at least a portion of the first connector 21 is composed of a magnet. At least a portion of the second connector 311 is composed of a magnetic catcher (such as a magnetically conductive material like iron, steel, or silicon steel) that can be attracted by a magnet. When the magnet and the magnetic catcher are attracted together, the first connector 21 and the second connector 311 are in a connected state; when the magnet and the magnetic catcher are separated, the first connector 21 and the second connector 311 are in a disconnected state.

[0195] In another embodiment, at least a portion of the first connector 21 is composed of a magnet, and at least a portion of the second connector 311 is also composed of a magnet, wherein the magnetic poles of the magnet constituting the first connector 21 and the magnet constituting the second connector 311 have opposite polarities. When the magnets of the first connector 21 and the second connector 311 are attracted to each other, the first connector 21 and the second connector 311 are in a connected state; when the magnets of the first connector 21 and the second connector 311 are disengaged, the first connector 21 and the second connector 311 are in a disengaged state.

[0196] In other embodiments, at least a portion of the second connector 311 is composed of a magnet, and at least a portion of the first connector 21 is composed of a magnetic attractor; when the magnet and the magnetic attractor are attracted together, the first connector 21 and the second connector 311 are in a connected state; when the magnet and the magnetic attractor are separated, the first connector 21 and the second connector 311 are in a disengaged state.

[0197] In the above embodiments, at least a portion of the first connector 21 is composed of a magnet, and at least a portion of the second connector 311 is composed of a magnet or a magnetic attractor. This design allows the first connector 21 and the second connector 311 to be connected by magnetic attraction. When the magnet and the magnetic attractor (or another magnet) enter the effective magnetic field range, they will actively attract each other under the action of magnetic force, thereby automatically correcting the positional deviation when they approach each other. This reduces the probability of connection failure due to a large positional deviation between the first connector 21 and the second connector 311. At the same time, since the magnet and the magnetic attractor can be designed with a small shape or volume, this connection structure is more suitable for space-constrained installation environments, helping to improve the overall structural compactness of the cleaning equipment.

[0198] In one embodiment of the present invention, the side of the first connector 21 corresponding to the side of the second connector 311 has a first adhesive portion, and the side of the second connector 311 corresponding to the side of the first connector 21 has a second adhesive portion. When the first adhesive portion and the second adhesive portion are bonded together, the first connector 21 and the second connector 311 are in a connected state; when the first adhesive portion and the second adhesive portion are separated, the first connector 21 and the second connector 311 are in a separated state.

[0199] Specifically, in one embodiment, the side of the first connector 21 corresponding to the side of the second connector 311 may have a first adhesive portion, and the side of the second connector 311 corresponding to the side of the first connector 21 may have a second adhesive portion. In another embodiment, the side of the first connector 21 corresponding to the side of the second connector 311 may have a second adhesive portion, and the side of the second connector 311 corresponding to the side of the first connector 21 may have a first adhesive portion.

[0200] The specific materials of the first and second adhesive portions are not limited. For example, in one embodiment, the first adhesive portion can be made of a high-adhesion pressure-sensitive adhesive, and its surface can be designed with microstructures, such as micro-bumps or micro-grooves. The second adhesive portion can also be made of a high-adhesion pressure-sensitive adhesive that matches the first adhesive portion, and can be designed with a corresponding microstructure surface to achieve mutual matching with the microstructure of the first adhesive portion. In another embodiment, the first and second adhesive portions can also adopt other reusable adhesive structures such as Velcro.

[0201] Since the first adhesive portion and the second adhesive portion can be bonded together to connect the first connector 21 and the second connector 311, this solution does not require complex mechanical interlocking components such as hooks or slots, thus simplifying the structure. Furthermore, since both the first adhesive portion and the second adhesive portion can be obtained from readily available, conventional adhesive components, no additional complex processing steps are required, thereby reducing production costs. Additionally, the adhesive connection itself does not significantly increase the thickness at the connection point, which facilitates a compact design for the cleaning equipment.

[0202] Referring to Figures 11, 12, 15, and 16, in one embodiment of the present invention, the shielding mechanism 30 further includes a drive assembly 32 and a scroll 33. The scroll 33 is rotatably mounted on the frame 10, and the drive assembly 32 is mounted on the frame 10 and has a rotating output end connected to the scroll 33. Specifically, the scroll 33 is rotatably mounted on the mounting base 50 and is disposed on the wall of the mounting base 50 on the side opposite to the rotary cleaning component 20. The rotatable mounting method can be a connection through a shaft hole or a rotatable connection through a rotary bearing. The length direction of the scroll 33 is consistent with the length direction of the mounting base 50. The drive assembly 32 is disposed on the frame 10. The drive assembly 32 can be directly mounted on the frame 10 or mounted on the mounting base 50, achieving an indirect connection with the frame 10 through the connection between the mounting base 50 and the frame 10. Optionally, in this embodiment, the drive assembly 32 is mounted on the mounting base 50 and disposed near the end of the scroll 33. The drive assembly 32 can be any structure that has a rotating output end, such as a combination of a motor and a gear assembly or a combination of a motor and a pulley assembly.

[0203] Please refer to Figures 17 and 24. One end of the blocking member 31 is wound around the scroll 33, and the other end of the blocking member 31 is a free end 312. The second connecting member 311 is disposed on the free end 312. The driving assembly 32 is used to drive the scroll 33 to rotate, thereby realizing the winding and unwinding of the blocking member 31. Specifically, the rotation output end of the driving assembly 32 is fixedly connected to the scroll 33. When the rotation output end rotates, it drives the scroll 33 to rotate synchronously, thereby realizing the winding and unwinding of the blocking member 31 on the scroll 33. The free end 312 of the blocking member 31 includes a sleeve 3121 and a connecting rod 3122. The connecting rod 3122 passes through the sleeve 3121 and is fixedly connected to the sleeve 3121. The two ends of the connecting rod 3122 extend to the outer sides of the two ends of the sleeve 3121, respectively. The second connecting member 311 is fixedly installed on the connecting rod 3122 and is located on the outer side of the end of the sleeve 3121. The installation direction is not limited. For example, it can be fixed by tight fit of shaft hole, fixed connection of pin and pin, fixed connection by snap-fit, etc.

[0204] In this embodiment, by setting up a drive component 32 and a scroll 33, the drive component 32 can drive the scroll 33 to rotate, thereby achieving automatic retraction and extension of the blocking component 31. This structure, on the one hand, enables fully automated operation of the blocking component 31's retraction and extension process, thus improving operational convenience, reducing manual intervention during the process, and enhancing the user experience. On the other hand, the winding and storing method of the blocking component 31 helps save internal installation space occupied by the retracted component, thus facilitating the optimization of the internal installation space layout of the rack 10.

[0205] In one embodiment of the present invention, referring to Figures 15 to 17, the shielding mechanism 30 further includes a cover 34, which is mounted on the frame 10. The cover 34 has a receiving cavity 344, in which the shielding member 31 is wound and stored. The cover 34 can be directly connected to a position on the frame 10 other than the mounting base 50, or it can be fixedly connected to the mounting base 50. Optionally, in this embodiment, the cover 34 is fixedly mounted on the mounting base 50, and the length direction of the cover 34 is consistent with the length direction of the mounting base 50. The cover 34 covers the shielding member 31 so that the shielding member 31 is wound and stored in the receiving cavity 344. The fixing method between the cover 34 and the mounting base 50 is not limited, including but not limited to bolt fixing connection. In order to reduce the installation space occupied by the cover 34 in the length direction, further, in one embodiment, neither end of the cover 34 in the length direction extends beyond the two ends of the mounting base 50 in the length direction. By providing a protective cover 34 and housing the shielding component 31 within its storage cavity 344, this design effectively prevents dust, moisture, and other impurities from entering the storage cavity 344. This protects the shielding component 31 from contamination and extends its service life. Simultaneously, the protective cover 34 also provides protection for the shielding component 31, reducing the probability of damage caused by accidental impacts during the operation or maintenance of the cleaning equipment.

[0206] Referring to Figures 18 to 24, in one embodiment of the present invention, a first card interface 51 is provided on the side of the frame 10 facing the protective cover 34, and a second card interface 343 is provided on the side of the protective cover 34 facing the frame 10. The first card interface 51 and the second card interface 343 are connected to each other and form a support hole 52 for supporting the scroll 33, and the scroll 33 is rotatably installed in the support hole 52 (as shown in Figure 16). Specifically, there are two first card interfaces 51 and two second card interfaces 343, located at both ends of the length direction of the protective cover 34. Each first card interface 51 is connected to a corresponding second card interface 343, forming a support hole 52. The two ends of the scroll 33 are rotatably installed in the two support holes 52 respectively.

[0207] In this embodiment, the support hole 52 for supporting the reel 33 is formed by the mutual docking of the first locking interface 51 and the second locking interface 343 provided on the frame 10 and the cover 34. During assembly, this structural design only requires aligning and fastening the frame 10 and the cover 34 to automatically form the complete support hole 52. Therefore, the step of installing an additional independent bearing seat or support frame can be eliminated, thus simplifying the assembly process, reducing assembly complexity, and improving assembly efficiency. Furthermore, when the reel 33 needs to be replaced or maintained, simply separating the cover 34 from the frame 10 will disengage the first locking interface 51 and the second locking interface 343, opening the support hole 52 and allowing the reel 33 to be directly removed. The entire operation does not require special tools or disassembly from the complex internal structure, thus reducing the difficulty of later maintenance.

[0208] Referring to Figures 16 and 17, in one embodiment of the present invention, the cover 34 includes a cover body 346 and an extension 341. The cover body 346 is fixedly connected to the mounting base 50 and covers the shielding member 31. Along the width direction of the mounting base 50, the extension 341 is disposed on one side of the cover body 346 in the width direction and is located on the outside of the width direction of the mounting base 50 (as shown in the X1 direction in Figure 15). Along the height direction of the cleaning device, one end of the extension 341 is connected to the cover body 346, and the other end extends toward the side close to the rotary cleaning member 20. A guide channel 345 communicating with the receiving cavity 344 is formed between the extension 341 and the frame 10. Specifically, a guide channel 345 is formed between the extension 341 and the outer wall of the mounting base 50, and the guide channel 345 extends along the width direction of the shielding member 31. The free end 312 of the shielding member 31 extends to the outside of the receiving cavity 344 via the guide channel 345.

[0209] By providing a guide channel 345 that communicates with the storage cavity 344, and allowing the free end 312 of the blocking member 31 to extend out of the storage cavity 344 through this channel, the guide channel 345 can guide the blocking member 31 during its opening and closing. Specifically, the guide channel 345 can effectively guide the blocking member 31 in and out of the storage cavity 344, reducing instability such as lateral swaying and vertical shaking that occurs during operation, thereby helping to ensure the accuracy and reliability of the opening and closing action of the blocking member 31.

[0210] Referring to Figures 16 and 17, in one embodiment of the present invention, the free end 312 and / or the second connector 311 can abut against the extension 341 to stop the free end 312 and the second connector 311 outside the receiving cavity 344 when the blocking member 31 retracts. In another embodiment, the second connector 311 does not abut against the extension 341, but rather the free end 312 abuts against the extension 341, thereby stopping the free end 312 and the second connector 311 outside the receiving cavity 344 when the blocking member 31 retracts. Specifically, the abutment of the free end 312 against the extension 341 means that the outer peripheral surface of the connecting rod 3122 sleeved in the sleeve 3121 abuts against the extension 341 through the sleeve 3121. In another embodiment, the free end 312 does not abut against the extension 341, but the second connector 311 abuts against the extension 341, so that when the blocking member 31 retracts, the free end 312 and the second connector 311 are stopped outside the receiving cavity 344. In other embodiments, both the second connector 311 and the free end 312 can abut against the extension 341, thereby stopping the free end 312 and the second connector 311 outside the receiving cavity 344 when the blocking member 31 retracts.

[0211] In the embodiment shown in Figure 14, when the guide member 12 is provided with a second guide surface 122, the second guide surface 122 is disposed below the extension 341 along the height direction of the cleaning device. During the retraction operation of the shielding member 31, the second guide surface 122 can guide the second connecting member 311 and / or the free end 312 to a position that abuts against the extension 341, thereby improving the positioning accuracy of the shielding member 31 at the retracted position.

[0212] Since the free end 312 and / or the second connector 311 can abut against the extension 341, the free end 312 and the second connector 311 can be stably stopped outside the receiving cavity 344 when the blocking member 31 retracts. This arrangement provides a constant pulling force to the blocking member 31 in the retracted state, thus preventing the blocking member 31 wound on the roll 33 from becoming loose and ensuring the tightness of the winding. Furthermore, this design ensures the repeatability of the blocking member 31's positioning each time it retracts, thereby improving the switching accuracy and efficiency between the first and second states.

[0213] Referring to Figures 25 and 26, in one embodiment of the present invention, a guide arc surface 53 is provided on the side of the frame 10 near the second connector 311, and the second connector 311 is provided with a mating surface 3112. After the first connector 21 disengages from the second connector 311, the guide arc surface 53 and the mating surface 3112 cooperate with each other to guide the second connector 311 to move along the contraction direction of the blocking member 31 to the position abutting against the extension 341. The mating surface 3112 can be an arc surface structure, an inclined surface structure, or any surface that can contact the first guide arc surface 53 to form a mating relationship. The guide arc surface 53 can be directly provided at other positions of the frame 10 except for the mounting base 50, or it can be provided on the mounting base 50. Optionally, in this embodiment, the guide arc surface 53 is provided on the mounting base 50 and is located on the mounting base 50 near the point where the first connector 21 and the second connector 311 disengage. Specifically, in this embodiment, a protrusion 55 is provided on the mounting base 50, and a guiding arc surface 53 is formed on the outer side of the protrusion 55. The second connector 311 includes a slot portion 3111 and a mounting portion 3113. The slot portion 3111 is provided at one end of the mounting portion 3113 away from the extension portion 341. The mounting portion 3113 is provided with a mounting hole, which cooperates with the shaft end of the connecting rod 3122 to realize the connection with the connecting rod 3122. The outer peripheral surface of the mounting portion 3113 is an arc surface, which forms the aforementioned mating surface 3112.

[0214] It should be noted that, referring to Figure 26, when the second connector 311 and the extension 341 abut against each other, the guide arc surface 53 at least partially abuts against the mating surface 3112, meaning that the two are still in a mating state. This arrangement not only guides the second connector 311 to move to the position abutting against the extension 341 after it disengages from the first connector 21, but also continues to provide guidance during the initial stage of the second connector 311's downward movement from the abutment position, thereby reducing the possibility of the second connector 311 deviating or getting stuck during the initial downward movement.

[0215] Since the second connector 311 is in a free or semi-free state after disengaging from the first connector 21, it is prone to wobbling or shifting during movement, which affects the positional accuracy of its contact with the extension 341. Therefore, this embodiment provides a guide arc surface 53 on the side of the frame 10 near the second connector 311 and a mating surface 3112 on the second connector 311. When the first connector 21 disengages from the second connector 311, the guide arc surface 53 and the mating surface 3112 cooperate to guide the second connector 311 to move along the contraction direction of the blocking member 31 to the position where it contacts the extension 341. This cooperation effectively constrains the movement trajectory of the second connector 311, ensuring it runs precisely along a preset path and ultimately reaches the predetermined position where it contacts the extension 341, thereby improving the contact accuracy between the second connector 311 and the extension 341.

[0216] It should be noted that in other embodiments, the retraction of the blocking member 31 may not be achieved by the free end 312 and / or the second connector 311 abutting against the extension 341. For example, referring to FIG33, in one embodiment, a stop member 54 may be provided on the mounting base 50, and the stop member 54 may extend at least partially into the retraction path of the second connector 311. During the retraction of the blocking member 31, the stop member 54 can form a stop with the second connector 311, thereby ensuring that the blocking member 31 is retracted into place. During the lowering of the blocking member 31, the stop member 54 can release the stop relationship with the second connector 311, thereby ensuring that the blocking member 31 can move down smoothly.

[0217] The specific structure of the stop member 54 is not limited; for example, it can be a protrusion structure, a groove structure, etc., as long as it can form a stop relationship with the second connector. Specifically, in this embodiment, the stop member 54 is the protrusion 55 in the above embodiment. The protrusion 55 has an insertion part 551 on the side facing the second connector 311, and the insertion part 551 can engage with the slot part 3111 on the second connector 311 to form a stop relationship.

[0218] Furthermore, in another embodiment, when the guide member 12 is provided with a second guide surface 122, the second guide surface 122 is disposed below the stop member 54 along the height direction of the cleaning device. During the retraction operation of the shield member 31, the second guide surface 122 can guide the second connector 311 to a position where it engages with the insertion portion 551 on the protrusion 55, thereby improving the positioning accuracy of the shield member 31 at the retracted position.

[0219] Referring to Figures 27 to 30, in one embodiment of the present invention, the drive assembly 32 includes a drive member 322 and a transmission assembly 323, with the drive member 322 mounted on the cover 34. In other embodiments, the drive member 322 may also be mounted on the frame 10. The drive member 322 has a rotary drive end 3221. The drive member 322 can be any drive mechanism with a rotary drive end 3221, such as a motor or hydraulic motor. Optionally, in this embodiment, the drive member 322 is a motor. The power input end of the transmission assembly 323 is connected to the rotary drive end 3221, and the power output end of the transmission assembly 323 forms a rotary output end.

[0220] The transmission component 323 can be a gear transmission component, a pulley transmission component, etc. Optionally, in this embodiment, referring to Figure 28, the transmission component 323 includes a first gear 3231 and a second gear 3232. The first gear 3231 is fixedly connected to the rotary drive end 3221 and forms a power input end. The second gear 3232 is fixedly connected to the end of the reel 33. The fixed connection method can be a tight fit connection between the shaft and hole, a snap-fit ​​connection, etc. The second gear 3232 meshes with the first gear 3231 and forms a power output end.

[0221] In this embodiment, by employing a structure combining the driving component 322 and the transmission assembly 323, different transmission forms of the transmission assembly 323 can be flexibly selected as needed. This design can effectively adjust the output speed and torque of the driving component 322, thereby more precisely matching the driving torque and operating speed required by the blocking component 31 during its retraction and extension. This not only ensures the smoothness and power of the blocking component 31's operation but also better meets the specific requirements for driving performance under different working conditions.

[0222] Referring to Figures 29 and 30, in embodiments of the present invention, the specific arrangement position of the drive member 322 on the mounting base 50 is not limited as long as the driving requirements for the reel 33 are met. For example, the rotation axis of the rotary drive end 3221 of the drive member 322 can be parallel to the height direction of the cleaning equipment, or it can be parallel to a direction perpendicular to the height direction of the cleaning equipment (i.e., the horizontal direction). Optionally, in one embodiment of the present invention, the rotation axis of the rotary drive end 3221 is parallel to the horizontal direction, so that the drive member 322 is placed horizontally on the frame 10 (i.e., horizontally on the mounting base 50). Specifically, the rotation axis of the rotary drive end 3221 can be parallel to the length direction, width direction, or any direction on the horizontal plane of the mounting base 50. By arranging the drive member 322 laterally on the frame 10, the space it occupies in the height direction of the frame 10 can be effectively reduced. This arrangement helps to reduce the overall height of the cleaning equipment, thereby making it easier to achieve a slim and lightweight design of the equipment.

[0223] Optionally, in this embodiment, referring to Figures 29 and 30, the rotation axis of the rotary drive end 3221 is parallel to the length direction of the mounting base 50, and the rotary drive end 3221 extends outward toward the length direction of the mounting base 50 to connect with the first gear 3231. This arrangement not only reduces the space occupied by the drive component 322 in the height direction of the cleaning equipment, but also reduces the installation space required in the width direction of the mounting base 50, thereby further optimizing the overall spatial layout and improving space utilization.

[0224] Referring to Figure 22, in one embodiment of the present invention, along the height direction of the cleaning device, the protective cover 34 has a receiving groove 347 on the side opposite to the rotary cleaning component 20, and the driving component 322 is at least partially located in the receiving groove 347. In one embodiment, the depth of the receiving groove 347 may be less than the height of the driving component 322, such that a portion of the driving component 322 is located within the receiving groove 347. In another embodiment, the depth of the receiving groove 347 may be equal to or greater than the height of the driving component 322, such that the driving component 322 can be completely located within the receiving groove 347. The opening of the receiving groove 347 may also be provided with a removable cover plate to protect the driving component 322 during installation. By providing the receiving groove 347 and placing at least a portion of the driving component 322 within the receiving groove 347, the space occupied by the driving component 322 above the mounting base 50 can be effectively reduced, thereby reducing the overall design height of the cleaning device and facilitating a slimmer design for the cleaning device.

[0225] Referring to Figures 30 and 32, in one embodiment of the present invention, a bracket 35 is connected to the protective cover 34. The bracket 35 and the protective cover 34 can be connected by various methods such as snap-fit ​​connection or bolt connection. A mounting cavity 351 is formed between the bracket 35 and the protective cover 34. The driving member 322 is housed in the mounting cavity 351, and the rotation driving end 3221 extends to the outside of the mounting cavity 351 and connects to the power input end of the transmission component 323. The mounting cavity 351 can be a closed cavity structure or a semi-closed cavity structure, etc., and this embodiment does not specifically limit it. The bracket 35 can be a U-shaped bracket 35, an L-shaped bracket 35, or other suitable shapes, as long as it can be connected to the protective cover 34 to form the mounting cavity 351. By setting up a bracket 35 and having the bracket 35 cooperate with the cover 34 to form a mounting cavity 351, the drive component 322 can be placed inside the mounting cavity 351. This not only reduces the probability of external dust, liquids and other impurities coming into direct contact with the drive component 322, but also provides mechanical protection for the drive component 322, reducing the risk of damage to the drive component 322 due to external collisions or interference.

[0226] It should be noted that, as shown in Figure 31, when the cover 34 is provided with a receiving groove 347, the bracket 35 is located above the receiving groove 347 and covers the opening of the groove, thereby cooperating with the receiving groove 347 to form an installation cavity 351.

[0227] Referring to Figures 31 and 32, in one embodiment of the present invention, a first connecting portion 342 is provided on the side of the cover 34 facing the bracket 35, and a second connecting portion 352 is provided on the side of the bracket 35 facing the cover 34. The first connecting portion 342 and the second connecting portion 352 are interlocked and fixed together, forming a through hole 353 for the rotary drive end 3221 to extend out. Specifically, semi-circular arc holes are symmetrically provided on the first connecting portion 342 and the second connecting portion 352. When the two are interlocked and fixed, the corresponding semi-circular arc holes align with each other to form a complete through hole 353. It should be noted that the fixed connection between the bracket 35 and the cover 34 can be achieved solely by the interlocking between the first connecting portion 342 and the second connecting portion 352, or other fixing positions (such as bolt connection holes or additional interlocking structures) can be added to further improve the stability and reliability of the connection. The specific snap-fit ​​structure of the first connecting part 342 and the second connecting part 352 is not limited. For example, a slot structure can be provided on the first connecting part 342, and a matching snap-fit ​​block structure can be provided on the second connecting part 352, so that a fixed connection is achieved by the mutual snap-fit ​​of the slot and the snap-fit ​​block. Alternatively, after the first connecting part 342 and the second connecting part 352 are mated, they together form a plug-in hole structure, and a positioning pin fastener is inserted into the plug-in hole to achieve reliable fixation of the two.

[0228] In this embodiment, a first connecting portion 342 and a second connecting portion 352 are provided to interlock with each other, forming a through hole 353 for the rotary drive end 3221 to extend out. This design, on the one hand, improves the positioning efficiency between the bracket 35 and the cover 34 through the interlocking structure of the first connecting portion 342 and the second connecting portion 352, thereby contributing to improved assembly efficiency. On the other hand, when it is necessary to disassemble the drive component 322, only the bracket 35 needs to be disassembled and the connection between the drive component 322 and the cover 34 needs to be broken. The drive component 322 can then be removed along the height direction of the cleaning equipment without horizontal movement. This feature helps reduce the horizontal design dimensions of the mounting cavity 351, thereby helping to reduce the overall design dimensions of the bracket 35.

[0229] Referring to Figure 34, this invention provides a control method for a cleaning device, which can control the operation of the cleaning device in the above embodiments. This control method lowers the blocking member 31 via the blocking mechanism 30, connecting the second connecting member 311 to the first connecting member 21. Then, it drives the rotary cleaning member 20 to move along a first rotation direction, causing the blocking member 31 to continue lowering, blocking the side of the rotary cleaning member 20 facing the surface to be cleaned. Thus, during the movement of the cleaning device, when the rotary cleaning member 20 passes over a specific obstacle, the blocking member 31 can block the side of the rotary cleaning member 20 facing the surface to be cleaned, achieving isolation between it and the ground. This reduces the probability of wastewater from the rotary cleaning member 20 being scraped off and contaminating the ground, especially reducing the probability of wastewater dripping from the wet rotary cleaning member 20 when passing over carpets and the probability of long fibers contacting the rotary cleaning member 20, thus reducing the risk of carpet contamination. Meanwhile, since the first rotation direction is opposite to the second rotation direction when the rotary cleaning component 20 performs a wet cleaning task, this ensures that the blocking action is triggered only when the rotary cleaning component 20 is not performing a wet cleaning task. This avoids the risk that the blocking component 31 may accidentally drop and interfere with the rotating rotary cleaning component 20 during normal wet cleaning operations, thus ensuring the normal wet cleaning operation of the rotary cleaning component 20.

[0230] When it is necessary to use the shielding member 31 to shield the side of the rotating cleaning member 20 facing the surface to be cleaned, the control method includes the following steps:

[0231] S1: Control the blocking mechanism 30 to lower the blocking member 31 so that the second connecting member 311 meets and connects to the first connecting member 21 on the movement path of the first connecting member 21.

[0232] In this step, during the process of the second connector 311 meeting and connecting with the first connector 21 along its movement path, the rotary cleaning component 20 can maintain its movement along the first rotation direction to drive the first connector 21 to move along the first rotation direction, thereby connecting with the second connector 311 on its movement path during the movement of the first connector 21. Alternatively, the rotary cleaning component 20 can start moving along the first rotation direction only after the second connector 311 has been lowered onto the movement path of the first connector 21, thereby driving the first connector 21 to move along the first rotation direction and connecting with the second connector 311. As long as it can be ensured that the first connector 21 can connect with the first connector 21 during the lowering process of the shielding component 31, this embodiment does not limit this.

[0233] S2: Drive the rotary cleaning component 20 to move along the first rotation direction, and through the connection of the first connector 21 and the second connector 311, drive the shielding component 31 to continue to descend so as to shield the side of the rotary cleaning component 20 facing the surface to be cleaned.

[0234] In this step, after the first connector 21 and the second connector 311 are connected, during the continued lowering of the shielding member 31, in one embodiment, the drive assembly 32 that drives the shielding member 31 to lower continuously operates, continuing to provide lowering power to achieve the lowering of the shielding member 31. This lowering action cooperates with the rotation of the rotary cleaning member 20 along the first rotation direction, working together to achieve the continued lowering of the shielding member 31. In another embodiment, the drive assembly 32 that drives the shielding member 31 to lower stops operating. At this time, only the rotation of the rotary cleaning member 20 along the first rotation direction is used to pull the shielding member 31 alone, achieving the continued lowering of the shielding member 31. It should be noted that the driving component 32 that drives the lowering of the blocking component 31 to stop operating means that the driving component 32 no longer actively drives the lowering of the blocking component 31. However, when the blocking component 31 is pulled, the blocking component 31 can still drive the output shaft of the driving component 32 to rotate. That is, after the driving component 32 stops operating, it will not brake the output shaft of the driving component 32. Under the action of external force, the output shaft of the driving component can still be passively rotated.

[0235] In the above steps, the second rotation direction is the rotation direction of the rotary cleaning component 20 when performing wet cleaning tasks, and the first rotation direction is opposite to the second rotation direction, that is, the first rotation direction is the non-cleaning operation direction of the rotary cleaning component 20.

[0236] It should be noted that the actions of lowering the drive shield 31 and rotating the drive rotary cleaning component 20 are both controlled and executed by the cleaning equipment's own control system.

[0237] Using the control method in this embodiment, when the cleaning equipment needs to pass through specific obstacles (such as thresholds or carpets) during its movement, the blocking mechanism 30 can be controlled to lower the blocking member 31, connecting the second connecting member 311 to the first connecting member 21. Then, the rotary cleaning member 20 is driven to move along the first rotation direction. The connection between the first connecting member 21 and the second connecting member 311 causes the blocking member 31 to continue lowering, thus blocking the rotary cleaning member 20 from the surface to be cleaned, thereby isolating the rotary cleaning member 20 from the ground. Therefore, this reduces the probability of wastewater being blown onto the ground and contaminating the passage area when the wet rotary cleaning member 20 passes through specific obstacles. In particular, it reduces the probability of wastewater dripping onto the carpet when the wet rotary cleaning member 20 passes through it, as well as the probability of long fibers on the carpet coming into contact with the rotary cleaning member 20, thereby reducing the risk of carpet contamination.

[0238] Furthermore, since the second rotation direction is the same as the rotation direction of the rotary cleaning component 20 when performing wet cleaning tasks, the first rotation direction is opposite to the second rotation direction. This arrangement ensures that the blocking action is only triggered when the rotary cleaning component 20 is not performing a wet cleaning task (i.e., running in a direction other than the second rotation direction). This avoids the risk of the blocking mechanism 30 accidentally lowering and interfering with the rotating rotary cleaning component 20 during normal wet cleaning operations, thereby ensuring the normal wet cleaning operation of the rotary cleaning component 20.

[0239] Please refer to Figure 35. In one embodiment of the present invention, in step S1: controlling the blocking mechanism 30 to lower the blocking member 31 so that the second connecting member 311 meets and connects with the first connecting member 21 on the movement path of the first connecting member 21, including the following steps:

[0240] S11: Drive the rotary cleaning component 20 to move in the first rotation direction, so that the rotary cleaning component 20 drives the first connecting component 21 to move in the first rotation direction;

[0241] S12: Control the blocking mechanism 30 to lower the blocking member 31, so that the second connecting member 311 moves to the movement path of the first connecting member 21. During the movement of the first connecting member 21 in the first rotation direction, the second connecting member 311 connects to the first connecting member 21 on the movement path of the first connecting member 21.

[0242] In this embodiment, the rotary cleaning component 20 is first driven to put the first connector 21 into motion; then, the blocking mechanism 30 is lowered to send the second connector 311 into the motion path of the first connector 21. This timing control allows the second connector 311 to dynamically dock with the first connector 21 during its movement. This shortens the connection response time and makes the connection between the first and second connectors smoother and more natural, thereby improving the connection efficiency between the first and second connectors 21.

[0243] Please refer to Figure 36. In one embodiment of the present invention, in step S1: controlling the blocking mechanism 30 to lower the blocking member 31 so that the second connecting member 311 meets and connects with the first connecting member 21 on the movement path of the first connecting member 21, including the following steps:

[0244] S11': Control the blocking mechanism 30 to lower the blocking member 31, so that the second connecting member 311 moves to the movement path of the first connecting member 21;

[0245] S12': Drive the rotary cleaning component 20 to move in the first rotation direction, so that the rotary cleaning component 20 drives the first connecting component 21 to move in the first rotation direction. During the movement of the first connecting component 21 in the first rotation direction, the second connecting component 311 is connected to the first connecting component 21 on the movement path of the first connecting component 21.

[0246] In this embodiment, by first moving the second connector 311 onto the movement path of the first connector 21, and then controlling the movement of the first connector 21, it is beneficial to ensure the accurate positioning of the second connector 311 and avoid motion interference between the second connector 311 and the first connector 21 during operation. This helps to improve the docking position accuracy between the first connector 21 and the second connector 311 and reduce the risk of connection failure between the first connector 21 and the second connector 311.

[0247] In one embodiment of the present invention, after the first connecting member 21 and the second connecting member 311 are connected, during the continued lowering of the shielding member 31, the driving component 32 that drives the shielding member 31 to lower continuously operates, continuing to provide lowering power so that the shielding member 31 is lowered. This lowering action cooperates with the rotation of the rotary cleaning member 20 along the first rotation direction, working together on the shielding member 31 to realize the continued lowering of the shielding member 31. During the continued lowering of the shielding member 31, the linear velocity of the first connecting member 21 moving along the first rotation direction is greater than or equal to the speed at which the shielding mechanism 30 lowers the shielding member 31.

[0248] During the continuous lowering of the blocking member 31, since the linear velocity of the first connecting member 21 moving along the first rotational direction is always greater than or equal to the speed at which the blocking mechanism 30 lowers the blocking member 31, this velocity relationship ensures that the blocking member 31 is always in a "taut" state. Therefore, the blocking member 31 will not have any slack sections during the entire lowering process, effectively reducing the risk of scratching or entanglement that may be caused by the slack of the blocking member 31. At the same time, this taut state also helps to ensure the continuity and stability of the lowering action, thereby improving the reliability and stability of the blocking member 31 in performing the blocking action.

[0249] In one embodiment of the present invention, along the forward direction of the cleaning device (as shown by the X-axis in Figure 6), one end of the cleaning device is the front end, and the other end is the rear end. The blocking member 31 is retracted at the front end. That is, when the blocking member 31 is in the retracted state, it is located at the front end of the cleaning device. When the blocking member 31 needs to perform a blocking action, the blocking member 31 is lowered and moves from the front end of the cleaning device towards the rear end of the cleaning device.

[0250] The rotary cleaning component 20 includes a first arc-shaped segment 201, a second arc-shaped segment 202, a first flat segment 203, and a second flat segment 204. The first arc-shaped segment 201 and the second arc-shaped segment 202 are distributed sequentially from the front end to the rear end, with the first arc-shaped segment 201 positioned closer to the front end of the cleaning device and the second arc-shaped segment 202 positioned closer to the rear end. The first flat segment 203 connects the first arc-shaped segment 201 and the second arc-shaped segment 202 and is positioned close to the surface to be cleaned. The second flat segment 204 connects the first arc-shaped segment 201 and the second arc-shaped segment 202 and is located on the side of the first flat segment 203 facing away from the surface to be cleaned. The first flat segment 203 and the second flat segment 204 are parallel or substantially parallel.

[0251] The rotary cleaning component 20 is driven to move along a first rotation direction, and the blocking component 31 continues to descend through the connection of the first connector 21 and the second connector 311 to block the side of the rotary cleaning component 20 facing the surface to be cleaned, including:

[0252] The shielding member 31 passes through and shields the first arc surface segment 201, the first flat surface segment 203, and the second arc surface segment 202 in sequence.

[0253] This configuration allows the shielding member 31 to sequentially cover the contours of the first arc-shaped segment 201, the first flat segment 203, and the second arc-shaped segment 202 during the shielding process of the rotating cleaning member 20, ultimately stopping at the position corresponding to the second arc-shaped segment 202. In this state, the shielding member 31 and the second arc-shaped segment 202 form a matching arc-shaped shielding structure. This arc-shaped shielding structure can effectively catch the wastewater dripping from the second arc-shaped segment 202 corresponding to the rotating cleaning member 20 and gather it inside the shielding member 31, thereby improving the shielding effect of the shielding member 31 on the side of the rotating cleaning member 20 facing the surface to be cleaned. At the same time, the arc-shaped shielding structure can also reduce the risk of wastewater gathered inside the shielding member 31 leaking out during the movement of the cleaning equipment, further enhancing the shielding effect of the shielding member 31 on the side of the rotating cleaning member 20 facing the surface to be cleaned.

[0254] In one embodiment of the present invention, after the shielding member 31 shields the side of the rotary cleaning member 20 facing the surface to be cleaned, when it is necessary to expose the side of the rotary cleaning member 20 facing the surface to be cleaned, the control method further includes:

[0255] The rotary cleaning component 20 is driven to move in the second rotation direction, and the shielding mechanism 30 is controlled to retract the shielding component 31 until the shielding component 31 exposes the rotary cleaning component 20 to the side facing the surface to be cleaned.

[0256] The second rotation direction is opposite to the first rotation direction, and the second rotation direction is consistent with the rotation direction of the rotary cleaning component 20 when performing the cleaning task.

[0257] Since the rotary cleaning component 20 can only perform cleaning tasks when its side facing the surface to be cleaned is exposed, in this embodiment, the second rotation direction is set to be consistent with the rotation direction of the rotary cleaning component 20 when performing the cleaning task. This means that when the blocking member 31 retracts, the rotary cleaning component 20 is already rotating in the second rotation direction required for performing the cleaning task. With this configuration, once the side of the rotary cleaning component 20 facing the surface to be cleaned is exposed, it can immediately perform the cleaning operation without needing to change direction. Therefore, the control logic of the cleaning equipment's operation can be simplified, and the cleaning efficiency of the cleaning equipment can also be improved.

[0258] In one embodiment of the present invention, during the process of driving the rotary cleaning member 20 to move in a second rotational direction and controlling the shielding mechanism 30 to retract the shielding member 31 until the shielding member 31 exposes the rotary cleaning member 20 toward the side of the surface to be cleaned, the linear velocity of the first connecting member 21 moving in the second rotational direction is less than or equal to the speed at which the shielding mechanism 30 retracts the shielding member 31.

[0259] Because the linear velocity of the first connecting member 21 moving along the second rotational direction is less than or equal to the speed at which the blocking mechanism 30 retracts the blocking member 31, this velocity relationship ensures that the blocking member 31 is always in a "taut" state. Therefore, the blocking member 31 will not experience any slack sections during the entire retraction process, effectively reducing the risk of scratching or entanglement that may be caused by the blocking member 31 sagging. At the same time, this taut state also helps ensure the continuity and stability of the blocking member 31's retraction action, thereby improving the reliability and consistency of the blocking member 31's retraction action.

[0260] In one embodiment of the present invention, the rotary cleaning component 20 is driven to move in a second rotational direction, and the blocking mechanism 30 is controlled to retract the blocking component 31 until the blocking component 31 exposes the side of the rotary cleaning component 20 facing the surface to be cleaned (that is, the first planar segment 203 of the rotary cleaning component 20 is exposed). The control method further includes:

[0261] Continue to drive the rotary cleaning component 20 to move in the second rotation direction and control the shielding mechanism 30 to continue to retract the shielding component 31 until the first connector 21 and the second connector 311 disengage.

[0262] It should be noted that after the first connector 21 and the second connector 311 disengage, the blocking member 31 will retract until it is fully retracted. The rotary cleaning member 20 continues to move in the second rotation direction to perform the cleaning task.

[0263] In this embodiment, after the shielding member 31 exposes the rotating cleaning member 20 towards the surface to be cleaned, the control system continues to drive the rotating cleaning member 20 to move in the second rotation direction and controls the shielding mechanism 30 to continue retracting the shielding member 31 until the first connecting member 21 and the second connecting member 311 disengage. This configuration allows for the automatic disengagement of the first connecting member 21 and the second connecting member 311 during the movement of the rotating cleaning member 20 along the second rotation direction. This process does not require additional operations or complex control commands, thus simplifying the control logic of the control system. Simultaneously, since the first connecting member 21 and the second connecting member 311 disengage, the rotational movement of the rotating cleaning member 20 and the retraction action of the shielding member 31 are completely decoupled, becoming two independent motion processes. This allows the rotating cleaning member 20 to operate continuously along the second rotation direction (i.e., the cleaning direction) without interference, no longer affected by the retraction action of the shielding member 31, effectively avoiding cleaning interruptions, speed fluctuations, or operational malfunctions that may occur due to linkage limitations, thereby improving the continuity of the cleaning process and overall work efficiency.

[0264] In one embodiment of the present invention, along the forward direction of the cleaning device (as shown by the X-axis in Figure 6), one end of the cleaning device is the front end, and the other end is the rear end. The blocking member 31 is retracted at the front end. That is, when the blocking member 31 is in the retracted state, it is located at the front end of the cleaning device. When the blocking member 31 needs to perform a blocking action, the blocking member 31 is lowered and moves from the front end of the cleaning device towards the rear end of the cleaning device.

[0265] The rotary cleaning component 20 includes a first arc-shaped segment 201, a second arc-shaped segment 202, a first flat segment 203, and a second flat segment 204. The first arc-shaped segment 201 and the second arc-shaped segment 202 are distributed sequentially from the front end to the rear end, with the first arc-shaped segment 201 positioned closer to the front end of the cleaning device and the second arc-shaped segment 202 positioned closer to the rear end of the cleaning device. The first flat segment 203 connects the first arc-shaped segment 201 and the second arc-shaped segment 202 and is positioned close to the surface to be cleaned. The second flat segment 204 connects the first arc-shaped segment 201 and the second arc-shaped segment 202 and is located on the side of the first flat segment 203 away from the surface to be cleaned.

[0266] The rotary cleaning component 20 is driven to move in a second rotational direction, and the shielding mechanism 30 is controlled to retract the shielding component 31 until the shielding component 31 exposes the rotary cleaning component 20 to the side facing the surface to be cleaned, including:

[0267] The shielding member 31 moves away from and exposes the second arc surface segment 202, the first flat surface segment 203 and the first arc surface segment 201 in sequence.

[0268] As the shielding member 31 retracts, it sequentially moves away from and exposes the second arc-shaped section 202, the first flat section 203, and the first arc-shaped section 201. This arrangement ensures that the side of the rotary cleaning member 20 facing the surface to be cleaned is completely exposed. This means that during normal cleaning operations, the shielding member 31 will not interfere with the cleaning function of the rotary cleaning member 20, thereby ensuring the efficiency and effectiveness of the cleaning operation.

[0269] In one embodiment of the present invention, the cleaning device is further provided with a sensor system, which is used to identify image information and / or three-dimensional information of obstacles, and the control method further includes:

[0270] The sensor system is used to detect image information and / or three-dimensional information of obstacles, and the type of obstacle is determined based on the image information and / or three-dimensional information of the obstacle;

[0271] Determine whether it is necessary to block the side of the rotating cleaning component 20 facing the surface to be cleaned based on the type of obstacle.

[0272] In this step, the sensor system can be a vision sensor, such as an RGB camera, used to acquire image information such as the color, texture, and shape of obstacles. The sensor system can also be a depth camera, such as an ultrasonic sensor, structured light camera, Time-of-Flight (ToF) camera, monocular vision system, or multi-view vision system, used to acquire 3D point cloud data and distance information of obstacles. The sensor system can also employ a multi-sensor fusion scheme, such as combining visual information with depth data, to improve the accuracy of obstacle recognition.

[0273] In this step, it is necessary to determine whether the side of the rotating cleaning component 20 facing the surface to be cleaned needs to be blocked based on the type of obstacle. Specifically, if the obstacle is determined to be a specific type of obstacle, such as a low threshold, small decorations on the ground, or a guide plate on the cleaning equipment base station—obstacles that normally allow the cleaning equipment to pass through—then the blocking component 31 needs to block the side of the rotating cleaning component 20 facing the surface to be cleaned. Conversely, if the obstacle type does not belong to the above-mentioned specific obstacles, then the blocking component 31 does not need to block the side of the rotating cleaning component 20 facing the surface to be cleaned.

[0274] In this embodiment, by setting a sensor system on the cleaning equipment, and the sensor system being used to identify the image information and / or three-dimensional information of obstacles, the cleaning equipment can automatically and accurately determine the type of obstacle, and based on this determination, determine whether the shielding component 31 needs to shield the rotating cleaning component 20, thereby improving the intelligence level, safety and adaptability of the cleaning operation.

[0275] 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.
