Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to cleaning components and cleaning equipment. Background Technology

[0002] With the rapid development of smart home technology, cleaning equipment such as robotic vacuum cleaners has provided significant assistance in reducing the burden of manual cleaning. These cleaning devices efficiently remove debris from the floor through the contact and friction between cleaning components such as rollers and the floor surface.

[0003] When cleaning equipment encounters carpet during the cleaning process, direct contact between the cleaning components and the carpet can easily cause contamination. To prevent carpet contamination, the cleaning equipment automatically raises the cleaning components to a certain height upon detecting carpet ahead, thus avoiding contact. To further enhance carpet protection, the cleaning components can be shielded with a partition or baffle after being raised.

[0004] For example, in the patent document CN222303849U, entitled "A Cleaning Brush and a Cleaning Device and System Including the Cleaning Brush", the roller brush is isolated from the surface to be cleaned by a partition plate. The partition plate is driven by a first driving device, and the roller brush is driven to rise and fall by a second driving device.

[0005] For example, in the patent document with announcement number CN119453864A entitled "Cleaning Robot and its Cleaning Components, Cleaning Mechanism and Cleaning Method", a baffle covers the cleaning part of the cleaning component. The baffle is driven by a drive component to move, and the cleaning component is driven to rise and fall by a lifting component.

[0006] However, the cleaning equipment in the prior art requires an additional drive device to drive the shielding components such as isolation plates or baffles. During use, the lifting of the cleaning components and the movement of the shielding components need to be controlled separately, which makes the control process more complicated and prone to problems of control asynchrony. Utility Model Content

[0007] In response to the patent documents with announcement numbers CN222303849U and CN119453864A, which require the addition of a driving device to drive the shielding component, the present invention provides a cleaning component and cleaning equipment, aiming to solve the problem that the existing cleaning equipment requires separate control of the lifting of the cleaning component and the movement of the shielding component.

[0016] During the process of the cleaning component moving away from the working surface, the driving mechanism drives the first rope segment to move the shielding component; during the process of the cleaning component moving closer to the working surface, the driving mechanism drives the second rope segment to move the shielding component.

[0017] In one alternative implementation, the linkage component includes a first rope segment connected to the shielding member;

[0018] During the process of the cleaning component moving away from the working surface, the driving mechanism drives the first rope segment to move the shielding component.

[0019] In one alternative embodiment, the linkage component further includes a second rope segment connected to the shielding member;

[0020] During the movement of the cleaning component toward the working surface, the driving mechanism drives the second rope segment to move the shielding component to a second position. At the second position, at least a portion of the shielding component exits the area between the cleaning component and the working surface.

[0021] In one alternative embodiment, the shielding member is rotatably connected to the cleaning member and can switch between the first position and the second position along the circumference of the cleaning member.

[0022] In one optional embodiment, the shielding member is provided with a connecting portion, the connecting portion being eccentrically arranged relative to the rotation axis of the shielding member, and both the first rope segment and the second rope segment are connected to the corresponding connecting portion.

[0023] In one optional embodiment, the driving mechanism has a translational driving member for driving the cleaning member to move. The movement paths of the driving member and the cleaning member intersect. During the movement of the cleaning member, the driving member drives the first rope segment or the second rope segment, thereby moving the shielding member.

[0024] In one alternative embodiment, the end of the first rope segment away from the shield is connected to the cleaning component, and the end of the second rope segment away from the shield is connected to the cleaning component.

[0025] Alternatively, the end of the first rope segment away from the shield is connected to the support, and the end of the second rope segment away from the shield is connected to the support.

[0026] In one alternative embodiment, the shielding member is rotatably or slidably connected to the support.

[0027] Alternatively, the shielding member is rotatably connected to the cleaning member and can rotate circumferentially along the cleaning member.

[0028] In one alternative embodiment, the shielding member includes:

[0029] The first arc-shaped plate is rotatably connected to the cleaning component and is also connected to the linkage assembly.

[0030] The second arc-shaped plate is slidably connected to the cleaning component and slidably engaged with the first arc-shaped plate along the circumference of the cleaning component.

[0037] The cleaning component provided by this utility model can achieve two actions with a single drive through a linkage component. Specifically, while the drive mechanism is driving the cleaning component to rise, the linkage component transmits power to the blocking component, causing the blocking component to simultaneously complete its blocking action. Thus, no additional drive device or separate control of the blocking component is required. By controlling only the drive mechanism, both the lifting of the cleaning component and the blocking action can be achieved simultaneously. This simplifies the control process, reduces the complexity of the control logic, and minimizes the risk of malfunctions caused by asynchronous control.

[0038] In addition, the movement of the shielding component is linked to the drive mechanism through the linkage component. No new drive device is needed. The shielding component can be driven by the power of the existing drive mechanism. This reduces the number of parts of the cleaning component, simplifies its overall structure, helps to reduce production costs and later maintenance difficulty, and improves the stability of equipment operation.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0057] In the patent documents with announcement numbers CN222303849U and CN119453864A, a new driving device is required to drive the shielding component, which results in a complex control process and a tendency for control asynchrony. This utility model provides a cleaning component and a cleaning device.

[0058] The following is a reference to the appendix. Figures 1-13 This paper introduces the cleaning components provided in the embodiments of this utility model.

[0059] Specifically, the cleaning components include a support 1, a cleaning component 2, a drive mechanism 3, a shielding component 4, and a linkage component 5.

[0060] The support 1 is used to connect to the main body of the cleaning equipment. Optionally, the support 1 has a receiving cavity 101 and an opening 102, with the opening 102 communicating with the receiving cavity 101. For example, the opening 102 is located at the bottom of the support 1. The support 1 can be configured as a housing.

[0061] The cleaning component 2 is movably disposed on the support 1 along the orientation of the opening 102, and at least a portion of the cleaning component 2 can enter or extend into the receiving cavity 101 through the opening 102.

[0062] For example, an opening 102 is located at the bottom of the support 1, and the cleaning component 2 is vertically and vertically mounted on the support 1. When the cleaning component 2 rises, at least a portion of the cleaning component 2 can enter the receiving cavity 101 through the opening 102. When the cleaning component 2 descends, at least a portion of the cleaning component 2 can extend out of the receiving cavity 101 from the opening 102 to clean the object to be cleaned. It can be understood that the cleaning component 2 can be a rotating cleaning component such as a roller, or a fixed cleaning component such as a mop or a brush.

[0063] The drive mechanism 3 is mounted on the support 1 and is connected to the cleaning component 2 for driving the cleaning component 2 to contact or detach from the working surface. For example, the drive mechanism 3 is used to drive the cleaning component 2 to rise or fall. The drive mechanism 3 includes, but is not limited to, gear and rack mechanisms and lead screw and nut mechanisms. It should be noted that the working surface is the surface of the object to be cleaned, such as the ground.

[0064] The shielding member 4 is movably disposed on the support 1. It should be noted that the shielding member 4 can be directly and movably connected to the support 1, or the shielding member 4 can be rotatably disposed on the cleaning member 2, thereby indirectly disposed on the support 1, which will be discussed below.

[0065] The linkage component 5 is connected to the drive mechanism 3 and the shielding member 4. The linkage component 5 is configured to drive the shielding member 4 to move to a first position as the cleaning member 2 moves in a direction away from the working surface, and at the first position, at least a portion of the shielding member 4 is located between the cleaning member 2 and the working surface.

[0066] In this embodiment, during the normal cleaning process of the cleaning component, the drive mechanism 3 drives the cleaning component 2 to move closer to the working surface so that the cleaning component 2 can contact the working surface and complete the cleaning operation.

[0067] When encountering items unsuitable for cleaning, such as carpets, the drive mechanism 3 drives the cleaning component 2 to move away from the working surface, so that the cleaning component 2 is separated from the working surface. At the same time, the linkage component 5 drives the shielding component 4 to move to the first position, so that at least part of the shielding component is located between the cleaning component and the working surface, thereby preventing the cleaning component 2 from contacting items such as carpets, and also preventing dirt or sewage from falling from the cleaning component 2 onto items such as carpets.

[0068] In related technologies, the lifting of the cleaning component 2 and the movement of the blocking component 4 need to be controlled independently, relying on an additional drive device. The control logic is complex and prone to coordination errors.

[0069] The cleaning component provided by this utility model can achieve two actions with one drive through the linkage component 5. That is, when the drive mechanism 3 drives the cleaning component 2 to rise, the linkage component 5 transmits the power of the drive mechanism 3 to the blocking component 4, so that the blocking component 4 can simultaneously complete the blocking action.

[0070] In this way, without the need for an additional drive device or separate control of the blocking component 4, the lifting of the cleaning component 2 and the blocking of the blocking component 4 can be achieved simultaneously by controlling the drive mechanism 3. This simplifies the control process, reduces the complexity of the control logic, and reduces the risk of failure caused by asynchronous control.

[0071] In addition, the action of the shield 4 is linked to the drive mechanism 3 through the linkage component 5. No new drive device is needed. The shield 4 can be driven by the power of the existing drive mechanism 3. This reduces the number of parts of the cleaning component, simplifies its overall structure, helps to reduce production costs and later maintenance difficulties, and improves the stability of equipment operation.

[0072] It can be understood that when no obstruction is needed, the obstruction element 4 can be manually reset by the user and held in its initial position by a latch or magnet. Alternatively, the obstruction element 4 can be reset by an elastic element, such as a spring, tension spring, or torsion spring.

[0073] Of course, the shielding member 4 is not limited to the above-mentioned reset method. For example, in some embodiments provided by this utility model, the linkage component 5 is also configured to drive the shielding member 4 to move to a second position during the process of the cleaning member 2 moving towards the working surface, and at the second position, at least part of the shielding member 4 exits the area between the cleaning member 2 and the working surface.

[0074] In this embodiment, the linkage component can not only automatically drive the shielding component into the shielding position when the cleaning component moves away from the working surface (e.g., when it is lifted), but also automatically drive the shielding component out of the shielding area when the cleaning component approaches the working surface (e.g., when it is lowered to prepare for cleaning). No manual intervention or additional control is required, thus realizing the fully automated coordination of the actions of the cleaning component and the shielding component.

[0075] refer to Figure 1 As shown, in some embodiments provided by this utility model, the cleaning component 2 includes a mounting base 202 and a roller 203.

[0076] The mounting base 202 is movably mounted on the support 1, for example, the mounting base 202 is vertically mounted on the support 1. The mounting base 202 is connected to the drive mechanism 3 so that the drive mechanism 3 can drive the mounting base 202 to move relative to the support 1. The roller 203 is rotatably connected to the mounting base 202, for example, the pivots at both ends of the roller 203 are connected to the mounting base 202.

[0077] In this embodiment, the rotation of the roller 203 can more efficiently remove stains from the working surface, improving the cleaning effect. It is understood that the roller 203 can rotate under the drive of a motor, or it can rotate under the drive of a suction airflow; there is no limitation on this.

[0078] refer to Figures 1-6 As shown, in some embodiments provided by this utility model, the linkage component 5 includes a rope body, which includes a first rope segment 501 and a second rope segment 502 connected together, that is, the first rope segment 501 and the second rope segment 502 are an integral structure. It is understood that the rope body can be made of one or more of natural fibers, synthetic fibers, and metal wire. Of course, the rope body can also be an iron chain. Both the first rope segment 501 and the second rope segment 502 are connected to the cleaning component 2.

[0079] During the movement of the cleaning component 2 away from the working surface, the drive mechanism drives the first rope segment 501 to move the blocking component 4. That is, during the upward movement of the cleaning component 2 driven by the drive mechanism 3, the drive mechanism 3 tensions the first rope segment 501, so that the first rope segment 501 moves the blocking component 4 to the first position.

[0080] As the cleaning component 2 moves toward the working surface, the drive mechanism drives the second rope segment 502 to move the blocking component 4. That is, as the drive mechanism 3 drives the cleaning component 2 to descend, the drive mechanism 3 tensions the second rope segment 502, so that the second rope segment 502 moves the blocking component 4 to the second position.

[0081] In this embodiment, when the cleaning equipment detects a scene such as a carpet, the drive mechanism 3 drives the cleaning component 2 to rise, and the first rope segment 501 drives the blocking component 4 to block the cleaning component 2; when it returns to a normal floor and needs to be cleaned, the drive mechanism 3 drives the cleaning component 2 to descend, and the second rope segment 502 drives the blocking component 4 to avoid the cleaning component 2. No manual operation is required, and the cleaning component can autonomously adapt to the switching of different cleaning scenarios.

[0082] The rope itself is flexible, meaning that the rope has a flexible shape, which makes the rope require less installation space. It is especially suitable for the compact layout environment inside the cleaning component and can complete the power transmission without increasing the volume of the support, thereby simplifying the structural design of the cleaning component.

[0083] In addition, the rope drives the blocking component 4 through the tensioning action, and the response is direct and precise. That is, the whole process does not require an intermediate conversion mechanism, which can reduce power loss and ensure the timeliness of blocking and avoidance actions.

[0084] Furthermore, if the rope wears out or breaks, only the rope itself needs to be replaced, without disassembling the complex mechanical structure, which reduces the time and cost of later maintenance. The connection between the rope and the cleaning component 2 and the drive mechanism 3 is simple, such as by hooks, binding, or wrapping, making it easy to adjust the rope length or connection position according to actual needs, thus improving the flexibility of the cleaning components during debugging.

[0085] It can be understood that the linkage component 5 is not limited to including the rope as described above; for example, refer to... Figures 7-11As shown, in other embodiments provided by this utility model, the linkage component 5 includes a first rope segment 501. Optionally, the material of the first rope segment 501 can be one or more of natural fibers, synthetic fibers, and metal wire. Of course, the first rope segment 501 can also be an iron chain. The first rope segment 501 is connected to the blocking member 4.

[0086] During the movement of the cleaning component 2 away from the working surface, the drive mechanism drives the first rope segment 501 to move the blocking component 4. That is, during the upward movement of the cleaning component 2 driven by the drive mechanism 3, the drive mechanism 3 tensions the first rope segment 501, so that the first rope segment 501 moves the blocking component 4 to the first position.

[0087] In this embodiment, the first rope segment 501 is flexible, that is, the shape of the first rope segment 501 is flexible, which makes the first rope segment 501 require less installation space, especially suitable for the compact layout environment inside the cleaning component, and can complete the power transmission without increasing the volume of the support 1, which can simplify the structural design of the cleaning component.

[0088] In addition, the first rope segment 501 drives the blocking component 4 through the tensioning action, which is direct and precise. That is, the whole process does not require an intermediate conversion mechanism, which can reduce power loss and ensure the timeliness of blocking and avoidance actions.

[0089] Furthermore, if the first rope segment 501 wears out or breaks, only the first rope segment 501 needs to be replaced, without disassembling the complex mechanical structure, which can reduce the time and cost of later maintenance. Moreover, the connection method between the first rope segment 501 and the cleaning component 2 and the drive mechanism 3 is simple, such as by using hooks, binding, or wrapping, which makes it easy to adjust the rope length or connection position according to actual needs, and can improve the debugging flexibility of the cleaning component.

[0090] As mentioned above, the first rope segment 501 can drive the blocking component 4 to block the cleaning component 2. When it is necessary to avoid the cleaning component 2, the blocking component 4 can be manually or driven by an elastic component to reset.

[0091] Of course, the blocking component 4 is not limited to the above-described reset method. For example, in other embodiments provided by this utility model, the linkage component 5 further includes a second rope segment 502, which is independent of the first rope segment 501. The material of the second rope segment 502 can be the same as that of the first rope segment 501. The second rope segment 502 is connected to the blocking component 4.

[0092] During the movement of the cleaning component 2 towards the working surface, the drive mechanism drives the second rope segment 502 to move the blocking component 4 to a second position. At the second position, at least a portion of the blocking component 4 is out of the area between the cleaning component and the working surface. Specifically, during the descent of the cleaning component 2 driven by the drive mechanism 3, the drive mechanism 3 tensions the second rope segment 502, causing the second rope segment 502 to move the blocking component 4 to the second position.

[0093] In this embodiment, the second rope segment 502 cooperates with the first rope segment 501 to drive the cleaning component 2 to rise and fall based on the drive mechanism 3, thereby causing the blocking component 4 to block or avoid the cleaning component 2. No manual operation is required, allowing the cleaning component to autonomously adapt to different cleaning scenarios. In addition, the advantages of moving the blocking component 4 through the second rope segment 502 are basically similar to those of the first rope segment 501, and will not be elaborated further.

[0094] In some embodiments provided by this utility model, the shielding member 4 is rotatably connected to the cleaning member 2 and can switch between a first position and a second position along the circumference of the cleaning member 2. Optionally, the shielding member 4 is an arc-shaped plate, and both ends of the arc-shaped plate are provided with end plates 4011. The two end plates 4011 are respectively rotatably connected to the two ends of the mounting base 202 so that the shielding member 4 can rotate along the circumference of the roller.

[0095] In this embodiment, the shielding member 4 is rotatably connected to the cleaning member 2, which can make full use of the three-dimensional space around the cleaning member 2. For example, the shielding member 4 can rotate around the rotation axis provided at the end of the cleaning member 2, conforming to the contour of the cleaning member 2, thereby making full use of the space around the cleaning room. There is no need to reserve a separate moving channel or guide structure for the shielding member 4, which is especially suitable for the narrow space environment inside the cleaning assembly, and can make the overall layout of the cleaning assembly more compact.

[0096] Furthermore, the shielding member 4 is provided with a connecting portion, which is eccentrically arranged relative to the rotation axis of the shielding member 4. For example, the connecting portion is provided on the end plate 4011. The first rope segment 501 and the second rope segment 502 are both connected to the corresponding connecting portion. The connecting portion can be a connecting hole or a connecting post.

[0097] For example, refer to Figures 1-7 As shown, there are two connecting parts, namely the first connecting part 403 and the second connecting part 404. The first connecting part 403 and the second connecting part 404 are both eccentrically arranged relative to the rotation axis of the shielding member 4. The first rope segment 501 is connected to the first connecting part 403, and the second rope segment 502 is connected to the second connecting part 404.

[0098] Optionally, the second connecting part 404 and the first connecting part 403 are located on opposite sides of the rotation axis of the cleaning component 2. It is understood that the first connecting part 403 and the second connecting part 404 can be arranged symmetrically or asymmetrically, and there is no limitation on this.

[0099] In some embodiments provided by this utility model, the drive mechanism 3 has a translational drive member 301 for driving the cleaning member 2 to move. The movement paths of the drive member 301 and the cleaning member 2 intersect, for example, their movement paths are perpendicular.

[0100] During the movement of the cleaning component 2, the driving component 301 drives either the first rope segment 501 or the second rope segment 502, thereby moving the shielding component 4. That is, the driving component 301 is connected to the linkage assembly 5. When the cleaning component 2 moves away from the working surface, the driving component 301 drives the first rope segment 501 to move the shielding component 4. When the cleaning component 2 moves closer to the working surface, the driving component 301 drives the second rope segment 502 to move the shielding component 4.

[0101] In this embodiment, the translational movement of the drive component 301 can be arranged along the horizontal direction of the support 1, while the lifting and lowering of the cleaning component 2 is carried out in the vertical direction. The two are linked together, which can make full use of the three-dimensional space inside the support 1.

[0102] Optionally, the drive mechanism 3 further includes a rotation drive device 302 and a gear 303. The rotation drive device is mounted on the support 1, and the gear 303 is connected to the output shaft of the rotation drive device 302. The drive member 301 is provided with a rack portion 3012, which meshes with the gear 303. Of course, the drive mechanism 3 can also be a lead screw and nut mechanism, for example, the nut of the lead screw and nut mechanism serves as the drive member 301.

[0103] Optionally, the cleaning component 2 is provided with a mating component 201, which slides in engagement with the support 1. For example, the mating component 201 is located on the top of the mounting base 202, and the mating component 201 can be configured as a slider. Further, the driving component 301 is provided with a guide ramp, and the mating component 201 is positioned on the movement path of the guide ramp 3011.

[0104] Optionally, the top of the support 1 has a through hole for the mating member 201 to pass through. The cleaning member 2 is disposed inside the support 1, and the mating member 201 extends out from the through hole at the top of the support 1. The protruding portion of the mating member 201 is used to mate with the guide ramp 3011. For example, the portion of the mating member 201 extending from the support 1 is provided with a roller so that the mating member 201 can abut against the guide ramp 3011 through the roller.

[0105] Optionally, during the movement of the driving member 301 in the first direction X, when the guide slope 3011 contacts the mating member 201, it can drive the mating member 201 to move upward along the guide slope 3011, thereby causing the cleaning member 2 to rise. During the movement of the driving member 301 in the second direction Y, the mating member 201 moves downward along the guide slope 3011, thereby causing the cleaning member 2 to descend. The first direction X and the second direction Y are opposite.

[0106] Of course, the driving component 301 is not limited to driving the cleaning component to rise and fall through the guide inclined surface 3011. For example, the driving component 301 can drive the cleaning component to rise and fall through the connecting rod. Specifically, the two ends of the connecting rod are rotatably connected to the driving component 301 and the mating component 201, respectively, that is, the driving component 301, the mating component 201, the connecting rod and the support 1 form a double slider mechanism.

[0107] refer to Figures 1-7 and Figure 11 As shown, in some embodiments provided by this utility model, the end of the first rope segment 501 away from the shielding member 4 is connected to the cleaning member 2. For example, the first rope segment 501 is snapped, glued, screwed or riveted to the cleaning member 2.

[0108] refer to Figures 1-7 As shown, optionally, the shielding member 4 is rotatably connected to the cleaning member 2, one end of the first rope segment 501 is connected to the cleaning member 2, and the other end is connected to the first connecting part 403. For example, one end of the first rope segment 501 is connected to the mating member 201 of the cleaning member 2, and the other end of the first rope segment 501 is connected to the first connecting part 403.

[0109] During the process of driving the cleaning component 2 to rise, the driving component 301 tensions the first rope segment 501 so that the first rope segment 501 drives the shielding component 4 to move to the first position.

[0110] In this embodiment, reference is made to Figure 7 As shown, it is assumed that when the driving component 301 translates in the first direction X, the cleaning component 2 rises, and when it translates in the second direction Y, the cleaning component 2 falls. The first direction X and the second direction Y are opposite.

[0111] refer to Figure 6 and Figure 7 As shown, since one end of the first rope segment 501 is connected to the mating part 201 of the cleaning component 2 and the other end is connected to the first connecting part 403, when the driving component 301 translates in the first direction X and drives the cleaning component 2 to rise, the first rope segment 501 rises synchronously with the cleaning component 2. At the same time, the first rope segment 501 is tensioned due to the continuous translation of the driving component 301, and the resulting tension directly acts on the eccentric first connecting part 403 of the blocking component 4, causing the blocking component 4 to rotate and block.

[0112] In this way, the coordinated action of multiple components can be achieved without additional control commands, ensuring that the shielding component 4 completes the shielding during the rising of the cleaning component 2, thus improving the timeliness of protection.

[0113] Furthermore, if it is necessary to adjust the timing or amplitude of the action of the shielding component 4, it can be achieved by simply changing the length of the first rope segment 501 or the eccentricity of the first connecting part 403, without having to modify the core structure of the driving component 301 or the cleaning component 2, which can reduce the debugging costs in the research and development and production process.

[0114] In some embodiments provided by this utility model, the driving member 301 is provided with a first guide member 6, and the first rope segment 501 wraps around the first guide member 6 on the side facing the first direction X. Optionally, the first guide member 6 may be a rotatable pulley, or the first guide member 6 may be a smooth guide post.

[0115] During the process of the driving component 301 driving the cleaning component 2 to rise, the first guide component 6 tensions the first rope segment 501 so that the first rope segment 501 drives the shielding component 4 to move to the first position.

[0116] In this embodiment, the first rope segment 501 wraps around the side of the first guide member 6 facing the first direction X, so that when the driving member 301 translates in the first direction X, the first rope segment 501 can be tensioned by the first guide member 6, thereby more effectively converting the translational action of the driving member 301 into a pulling force on the blocking member 4. At the same time, by wrapping around the first guide member 6, the path of the first rope segment 501 is more stable, avoiding unstable power transmission or jamming caused by the deviation of the first rope segment 501.

[0117] In addition, the first guide member 6 can reduce the friction force on the first rope segment 501, improve the transmission efficiency, ensure that the blocking member 4 is more sensitive, and extend the service life of the first rope segment 501.

[0118] refer to Figures 1-7 and Figure 11 As shown, in some embodiments provided by this utility model, the end of the second rope segment 502 away from the shielding member 4 is connected to the cleaning member 2. For example, the second rope segment 502 is snapped, glued, screwed, or riveted to the cleaning member 2.

[0119] refer to Figures 1-7 As shown, optionally, the shielding member 4 is rotatably connected to the cleaning member 2, one end of the second rope segment 502 is connected to the cleaning member 2, and the other end is connected to the second connecting part 404. For example, one end of the second rope segment 502 is connected to the mating member 201 of the cleaning member 2, and the other end of the second rope segment 502 is connected to the second connecting part 404.

[0120] Optionally, as described above, the second rope segment 502 and the first rope segment 501 can be an integral structure, and the joint between the first rope segment 501 and the second rope segment 502 is connected to the mating part 201 of the cleaning component 2. Alternatively, the second rope segment 502 and the first rope segment 501 are independent units, and both the first rope segment 501 and the second rope segment 502 are connected to the mating part 201 of the cleaning component 2.

[0121] During the descent of the cleaning component 2, the driving component 301 tensions the second rope segment 502, so that the second rope segment 502 drives the shielding component 4 to move to the second position.

[0122] In this embodiment, reference is made to Figure 3 , Figure 4 and Figure 7 As shown, since one end of the second rope segment 502 is connected to the mating part 201 of the cleaning part 2 and the other end is connected to the second connecting part 404, when the driving part 301 translates in the second direction Y and drives the cleaning part 2 to descend, the second rope segment 502 rises synchronously with the cleaning part 2. At the same time, the second rope segment 502 is tensioned due to the continuous translation of the driving part 301, and the resulting tension acts directly on the eccentric second connecting part 404 of the blocking part 4, causing the blocking part 4 to rotate to avoid.

[0123] In this way, the coordinated action of multiple components can be achieved without additional control commands, ensuring that the blocking component 4 can avoid the cleaning component 2 during its descent, thus improving the timeliness of the avoidance.

[0124] Furthermore, if it is necessary to adjust the timing or amplitude of the action of the shielding component 4, it can be achieved by simply changing the length of the second rope segment 502 or the eccentricity of the second connecting part 404, without having to modify the core structure of the driving component 301 or the cleaning component 2, which can reduce the debugging costs in the research and development and production process.

[0125] In some embodiments of this utility model, the driving member 301 is provided with a second guide member 7, and the second rope segment 502 passes around the second guide member 7 on the side facing the second direction Y. Optionally, the second guide member 7 can be a rotatable pulley, or the second guide member 7 can also be a smooth guide post.

[0126] During the process of the driving component 301 driving the cleaning component 2 to descend, the second guide component 7 tensions the second rope segment 502 so that the second rope segment 502 drives the shielding component 4 to avoid at least part of the working surface of the cleaning component 2.

[0127] In this embodiment, the second rope segment 502 wraps around the side of the second guide member 7 facing the second direction Y, so that when the driving member 301 translates in the second direction Y, the second rope segment 502 can be tensioned by the second guide member 7, thereby more effectively converting the translational action of the driving member 301 into a pulling force on the blocking member 4. At the same time, by wrapping around the second guide member 7, the path of the second rope segment 502 is more stable, avoiding unstable power transmission or jamming caused by the deviation of the second rope segment 502.

[0128] In addition, the second guide member 7 can reduce the friction force on the second rope segment 502, improve the transmission efficiency, ensure that the blocking member 4 responds more sensitively, and extend the service life of the second rope segment 502.

[0129] Understandably, when the first guide member 6 tensions the first rope segment 501, the first rope segment 501 pulls the blocking member 4, and the blocking member 4, in turn, pulls the second rope segment 502 back to its original position. Similarly, when the second guide member 7 tensions the second rope segment 502, the second rope segment 502 pulls the blocking member 4, and the blocking member 4, in turn, pulls the first rope segment 501 back to its original position.

[0130] In some embodiments provided by this utility model, reference is made to Figure 6 and Figure 7 As shown, the cleaning assembly also includes a reversing element 8, which can be a pulley or a smooth column, and can be mounted on the support 1. It is understood that the reversing element 8 functions similarly to a fixed pulley, used to change the direction of force.

[0131] The first rope segment 501 can be routed around the corresponding reversing member 8 to adjust its direction, allowing it to bypass obstacles and connect to the first connecting part 403 of the blocking member 4, thereby transmitting tension. Furthermore, the reversing member 8 can adjust the direction of tension in the first rope segment 501, making the direction of tension more aligned with the force requirements of the blocking member 4 to achieve blocking motion.

[0132] Similarly, the second rope segment 502 can be routed around the corresponding reversing member 8 to adjust its direction, allowing it to bypass obstacles and connect to the second connecting part 404 of the blocking member 4, thereby achieving the transmission of tension. Furthermore, the reversing member 8 can adjust the direction of tension in the second rope segment 502, making the direction of tension more aligned with the force requirements of the blocking member 4 for obstacle avoidance movement.

[0133] It is understood that the shielding member 4 is not limited to being rotatably connected to the cleaning member 2. For example, the shielding member 4 can be rotatably or slidably connected to the support 1, as shown in the reference. Figure 11 As shown, based on this, the end of the first rope segment 501 or the second rope segment 502 away from the shielding member 4 can also be connected to the cleaning member 2, which will be discussed below.

[0134] Of course, the end of the first rope segment 501 or the second rope segment 502 that is away from the shielding member 4 is not limited to being connected to the cleaning member 2. For example, in other embodiments provided by this utility model, the end of the first rope segment 501 that is away from the shielding member 4 is connected to the support 1, and the end of the second rope segment 502 that is away from the shielding member 4 is connected to the support 1.

[0135] For example, refer to Figure 8 As shown, in some embodiments provided by this utility model, the driving component 301 is provided with a first guide component 6, which may be a pulley or a guide post.

[0136] One end of the first rope segment 501 is connected to the support 1, and the other end is connected to the shield 4. For example, the first rope segment 501 is connected to the first connecting portion 403 of the shield 4. Optionally, the shield 4 can be rotatably connected to the cleaning component 2 as described above, or the shield 4 can also be movably connected to the support 1, which will be discussed below.

[0137] The first rope segment 501 passes around the first guide member 6 on the side facing the first direction X. During the process of the driving member 301 driving the cleaning member 2 to rise, the first guide member 6 tensions the first rope segment 501 so that the first rope segment 501 drives the shielding member 4 to move to the first position.

[0138] refer to Figure 8 As shown, in this embodiment, the rotatable connection between the shielding member 4 and the cleaning member 2 is used as an example for description.

[0139] When the drive unit 301 moves in the first direction X, the cleaning unit 2 rises, the first connecting part 403 of the shielding unit 4 rises, and at this time, the end of the first rope segment 501 connected to the first connecting part 403 also rises.

[0140] The first rope segment 501 wraps around the first guide member 6 on the side facing the first direction X. Therefore, when the first guide member 6 moves in the first direction X with the driving member 301, the first rope segment 501 can be tensioned. Furthermore, the first guide member 6 acts as a movable pulley, that is, during the movement of the first guide member 6, the end of the first rope segment 501 connected to the support 1 is fixed, and the displacement of the end of the first rope segment 501 connected to the first connecting part 403 is twice the displacement of the first guide member 6.

[0141] Therefore, although the end of the first rope segment 501 connected to the first connecting part 403 also rises with the cleaning component 2, the displacement of the first rope segment 501 is greater than the rise of the cleaning component 2, so the first rope segment 501 can still pull the blocking component 4.

[0142] In summary, in this embodiment, even if the first connecting part 403 rises with the cleaning member 2, causing one end of the first rope segment 501 to be raised (which may offset part of the tension), the overall displacement of the first rope segment 501 is amplified due to the pulley effect of the guide member, which can still generate sufficient tension to drive the blocking member 4 to rotate, thus avoiding the first rope segment 501 from slackening due to the synchronous movement of the connecting part of the cleaning member 2 and the blocking member 4, and ensuring that the blocking action is reliably executed.

[0143] Furthermore, the eccentricity of the first connecting part 403 relative to the rotation axis of the blocking member 4 can be reduced, so that the first rope segment 501 can drive the blocking member 4 to rotate a large angle with a small displacement.

[0144] In the case of the movable connection between the shield 4 and the support 1, the first rope segment 501 can obviously also drive the shield 4 to move.

[0145] Optionally, a reversing element 8 is provided on the support 1, and the first rope segment 501 passes through the reversing element 8. The specific analysis has been discussed above and will not be repeated here.

[0146] refer to Figure 8 As shown, the number of reversing elements 8 can be one or more. For the first reversing element 8 that the first rope segment 501 passes through after passing the first guide element 6, the end of the line connecting the center of the reversing element 8 and the center of the first guide element 6 closest to the first guide element 6 is always inclined towards the first direction X. This arrangement ensures that the first rope segment 501 is tensioned during the translation of the drive element 301 in the first direction X, but is not tensioned during the translation in the second direction Y.

[0147] For example, when the drive member 301 translates in the first direction X, the relative distance between the first guide member 6 and the reversing member 8 gradually increases. As the connecting line is inclined in the first direction X, the path of the first rope segment 501 from the first guide member 6 to the reversing member 8 will be naturally lengthened, thereby reliably tensioning and causing the blocking member 4 to avoid it. When the drive member 301 translates in the second direction Y, the first guide member 6 moves in the opposite direction. The inclined connecting line causes the rope segment path to shorten naturally, and the rope segment becomes slack, without generating additional tension.

[0148] refer to Figure 8 As shown, optionally, the drive unit 301 is provided with a second guide 7, which may be a pulley or a guide post.

[0149] One end of the second rope segment 502 is connected to the support 1, and the other end is connected to the shielding member 4. For example, the second rope segment 502 is connected to the second connecting portion 404 of the shielding member 4. Optionally, the shielding member 4 can be rotatably connected to the cleaning member 2 as described above, or the shielding member 4 can also be movably connected to the support 1, which will be discussed below. It is understood that the second rope segment 502 can be an integral structure with the first rope segment 501, or they can be independent units.

[0150] The second rope segment 502 passes around the second guide member 7 on the side facing the second direction Y. During the process of the driving member 301 driving the cleaning member 2 to descend, the second guide member 7 tensions the second rope segment 502 so that the second rope segment 502 drives the blocking member 4 to move to the second position.

[0151] In this embodiment, the rotatable connection between the shielding member 4 and the cleaning member 2 is used as an example for description.

[0152] When the driving member 301 translates in the second direction Y, the second guide member 7 moves synchronously with the driving member 301, and the second rope segment 502 passing around it and facing the second direction Y is tensioned, so that the tension of the second rope segment 502 directly acts on the second connecting part 404 of the shielding member 4.

[0153] The second guide member 7 functions like a movable pulley. During the movement of the second guide member 7, the end of the second rope segment 502 connected to the support 1 is fixed, and the displacement of the end of the second rope segment 502 connected to the second connecting part 404 is twice the displacement of the second guide member 7. Furthermore, the second connecting part 404 also tensions the second rope segment 502 as the cleaning member 2 descends.

[0154] Therefore, to avoid excessive displacement of the second rope segment 502 and mismatch with the rotation angle of the blocking member 4, the eccentricity of the second connecting portion 404 relative to the rotation axis of the blocking member 4 can be appropriately increased. For example, see... Figure 6 As shown, the eccentricity of the second connecting part 404 is greater than the eccentricity of the first connecting part 403.

[0155] In the case of the movable connection between the shield 4 and the support 1, the second rope segment 502 can obviously drive the shield 4 to move.

[0156] Optionally, a reversing element 8 is provided on the support 1, and the second rope segment 502 passes through the reversing element 8. The specific analysis has been discussed above and will not be repeated here.

[0157] refer to Figure 8As shown, the number of reversing members 8 can be one or more. For the first reversing member 8 that the second rope segment 502 passes through after passing the second guide member 7, the end of the line connecting the center of the reversing member 8 and the center of the second guide member 7 closest to the second guide member 7 is always inclined in the second direction Y. This arrangement ensures that the second rope segment 502 can be tensioned during the translation of the drive member 301 in the second direction Y, but will not be tensioned during the translation in the second direction Y.

[0158] For example, when the drive member 301 translates in the second direction Y, the relative distance between the second guide member 7 and the reversing member 8 gradually increases. As the connecting line tilts in the second direction Y, the path of the second rope segment 502 from the second guide member 7 to the reversing member 8 is naturally lengthened, thereby reliably tensioning and causing the blocking member 4 to avoid it. When the drive member 301 translates in the first direction X, the second guide member 7 moves in the opposite direction. The tilted connecting line causes the rope segment path to shorten naturally, and the rope segment becomes slack, without generating additional tension.

[0159] Of course, the first guide member 6 and the second guide member 7 are not limited to being installed on the support 1.

[0160] For example, refer to Figure 9 As shown, in some embodiments of this utility model, the cleaning component 2 is provided with a first guide component 6. The first guide component 6 may be a pulley or a guide post. For example, the first guide component 6 is disposed on the mating component 201.

[0161] One end of the first rope segment 501 is connected to the support 1, and the other end is connected to the shield 4. For example, the first rope segment 501 is connected to the first connecting portion 403 of the shield 4. Optionally, the shield 4 can be rotatably connected to the cleaning component 2 as described above, or the shield 4 can also be movably connected to the support 1, which will be discussed below.

[0162] The first rope segment 501 wraps around the top of the first guide member 6. During the process of the driving mechanism 3 driving the cleaning member 2 to rise, the first guide member 6 tensions the first rope segment 501 so that the first rope segment 501 drives the shielding member 4 to move to the first position.

[0163] In this embodiment, the rotatable connection between the shielding member 4 and the cleaning member 2 is used as an example for description.

[0164] When the drive unit 301 moves in the first direction X, the cleaning unit 2 rises, the first connecting part 403 of the shielding unit 4 rises, and at this time the end of the first rope segment 501 connected to the first connecting part 403 also rises.

[0165] The first rope segment 501 wraps around the upper side of the first guide member 6, so the first guide member 6 can be tensioned when it rises with the cleaning member 2. Furthermore, the first guide member 6 functions as a movable pulley; that is, during the movement of the first guide member 6, the end of the first rope segment 501 connected to the support 1 is fixed, and the displacement of the end of the first rope segment 501 connected to the first connecting part 403 is twice the displacement of the first guide member 6.

[0166] Therefore, although the end of the first rope segment 501 connected to the first connecting part 403 also rises with the cleaning component 2, the displacement of the first rope segment 501 is greater than the rise of the cleaning component 2, so the first rope segment 501 can still pull the blocking component 4.

[0167] In summary, in this embodiment, even if the first connecting part 403 rises with the cleaning member 2, causing one end of the first rope segment 501 to be raised (which may offset part of the tension), the overall displacement of the first rope segment 501 is amplified by the pulley effect of the first guide member 6, which can still generate sufficient tension to drive the blocking member 4 to rotate, thus avoiding the first rope segment 501 from slackening due to the synchronous movement of the cleaning member 2 and the connecting part of the blocking member 4, and ensuring that the blocking action is reliably executed.

[0168] Furthermore, the eccentricity of the first connecting part 403 relative to the rotation axis of the blocking member 4 can be reduced, so that a small displacement of the first rope segment 501 can drive the blocking member 4 to rotate a large angle.

[0169] In the case of the movable connection between the shield 4 and the support 1, the first rope segment 501 can obviously drive the shield 4 to move.

[0170] Optionally, a reversing element 8 is provided on the support 1, and the first rope segment 501 passes through the reversing element 8. The specific analysis has been discussed above and will not be repeated here.

[0171] Optionally, refer to Figure 9 As shown, the cleaning component 2 is provided with a second guide 7, which can be a pulley or a guide post. For example, the second guide 7 is provided on the mating component 201.

[0172] One end of the second rope segment 502 is connected to the support 1, and the other end is connected to the shielding member 4. For example, the second rope segment 502 is connected to the second connecting portion 404 of the shielding member 4. Optionally, the shielding member 4 can be rotatably connected to the cleaning member 2 as described above, or the shielding member 4 can also be movably connected to the support 1, which will be discussed below. It is understood that the second rope segment 502 can be an integral structure with the first rope segment 501, or they can be independent units.

[0173] The second rope segment 502 passes around the bottom of the second guide member 7. During the process of the driving mechanism 3 driving the cleaning member 2 to descend, the second guide member 7 tensions the second rope segment 502 so that the second rope segment 502 drives the shielding member 4 to avoid at least part of the working surface of the cleaning member 2.

[0174] In this embodiment, the rotatable connection between the shielding member 4 and the cleaning member 2 is used as an example for description.

[0175] When the drive member 301 moves in the second direction Y, the cleaning member 2 descends, and the second guide member 7 moves synchronously with the cleaning member 2. The second rope segment 502 passing under the second guide member 7 is tensioned, so that the tension of the second rope segment 502 directly acts on the second connecting part 404 of the shielding member 4.

[0176] The second guide member 7 functions like a movable pulley. During the movement of the second guide member 7, the end of the second rope segment 502 connected to the support 1 is fixed, and the displacement of the end of the second rope segment 502 connected to the second connecting part 404 is twice the displacement of the second guide member 7. Furthermore, the second connecting part 404 also tensions the second rope segment 502 as the cleaning member 2 descends.

[0177] Therefore, to avoid excessive displacement of the second rope segment 502 and mismatch with the rotation angle of the blocking member 4, the eccentricity of the second connecting portion 404 relative to the rotation axis of the blocking member 4 can be appropriately increased. For example, see... Figure 6 As shown, the eccentricity of the second connecting part 404 is greater than the eccentricity of the first connecting part 403.

[0178] In the case of the movable connection between the shield 4 and the support 1, the second rope segment 502 can naturally drive the shield 4 to move.

[0179] Optionally, a reversing element 8 is provided on the support 1, and the second rope segment 502 passes through the reversing element 8. The specific analysis has been discussed above and will not be repeated here.

[0180] Optionally, provided that the shielding member 4 and the cleaning member 2 are rotatably connected, the specific form of the first rope segment 501 and the specific form of the second rope segment 502 can be independent of each other; that is, the arrangement of the first rope segment 501 and the arrangement of the second rope segment 502 can be the same or different. Therefore, the arrangement of the first rope segment 501 can be any one of the above embodiments, and the arrangement of the second rope segment 502 can be any one of the above embodiments.

[0181] Of course, the shielding component 4 is not limited to a rotatable connection with the cleaning component 2, see reference. Figure 12 As shown, in some embodiments provided by this utility model, the shielding member 4 can be rotatably connected to the support 1, that is, the shielding member 4 can shield or avoid the cleaning member 2 by rotating relative to the support 1. Alternatively, refer to Figure 13 As shown, the shielding member 4 can be slidably connected to the support 1, that is, the shielding member 4 can shield or avoid the cleaning member 2 by sliding relative to the support 1.

[0182] Optionally, corresponding to the rotatable or slidable connection between the shielding member 4 and the support 1, refer to Figure 8 and Figure 9 As shown, the end of the first rope segment 501 away from the shield 4 can be connected to the support 1, and the first guide 6 can be set on the driving component 301 or the mating component 201 of the cleaning component 2.

[0183] Optionally, corresponding to the rotatable or slidable connection between the shielding member 4 and the support 1, refer to Figure 8 and Figure 9 As shown, the end of the second rope segment 502 away from the shield 4 can be connected to the support 1, and the second guide 7 can be set on the driving component 301 or the mating component 201 of the cleaning component 2.

[0184] Of course, the first rope segment 501 and the second rope segment 502 are not limited to the connection forms described in the above embodiments, corresponding to the rotatable or sliding connection between the shielding member 4 and the support 1.

[0185] For example, refer to Figures 10-13 As shown, in some embodiments provided by this utility model, the shielding member 4 is rotatably connected or slidably connected to the support 1.

[0186] One end of the first rope segment 501 is connected to the driving member 301 or the cleaning member 2, and the other end is connected to the blocking member 4. During the process of the cleaning member 2 rising, the driving member 301 or the cleaning member 2 tensions the first rope segment 501 so that the first rope segment 501 drives the blocking member 4 to move to the first position.

[0187] In this embodiment, the movement of the driving component 301 or the cleaning component 2 can be directly transmitted to the blocking component 4 through the first rope segment 501, reducing intermediate steps and improving response speed. At the same time, regardless of whether the blocking component 4 and the support 1 are rotatably connected or slidably connected, the flexibility of the first rope segment 501 can adapt to its movement trajectory, ensuring effective force transmission.

[0188] Optionally, refer to Figures 10-13 As shown, one end of the second rope segment 502 is connected to the driving member 301 or the cleaning member 2, and the other end is connected to the blocking member 4. During the descent of the cleaning member 2, the driving member 301 or the cleaning member 2 tensions the second rope segment 502 so that the second rope segment 502 drives the blocking member 4 to move to the second position.

[0189] In this embodiment, the movement of the driving component 301 or the cleaning component 2 can be directly transmitted to the blocking component 4 through the second rope segment 502, reducing intermediate steps and improving response speed. At the same time, regardless of whether the blocking component 4 and the support 1 are rotatably or slidably connected, the flexibility of the first rope segment 501 can adapt to its movement trajectory, ensuring effective force transmission.

[0190] In some embodiments provided by this utility model, the drive mechanism 3 includes a rotation drive device 302 and a gear 303. The rotation drive device 302 is disposed on the support 1, and the gear 303 is connected to the output shaft of the rotation drive device 302. The drive member 301 is provided with a rack portion 3012, which meshes with the gear 303. For example, the rotation drive device 302 is a motor.

[0191] In this embodiment, the gear 303 meshes with the rack 3012 for transmission. The displacement of the drive component 301 can be precisely adjusted by controlling the rotation angle of the rotation drive device 302, thereby improving control accuracy. Furthermore, the meshing of the gear 303 with the rack 3012 results in a compact structure with strong load-bearing capacity, making it suitable for a compact layout of cleaning components.

[0192] In some embodiments provided by this utility model, the shielding member 4 includes a first arc-shaped plate 401 and a second arc-shaped plate 402.

[0193] The first arc-shaped plate 401 is rotatably connected to the cleaning component 2 and connected to the linkage assembly 5. For example, both ends of the first arc-shaped plate 401 are provided with end plates 4011, and the end plates 4011 at both ends of the first arc-shaped plate 401 are rotatably connected to both ends of the mounting base 202, and at least one end plate 4011 is connected to at least one of the first rope segment 501 and the second rope segment 502, that is, the end plate 4011 is provided with at least one of the first connecting part 403 and the second connecting part 404.

[0194] The second arc-shaped plate 402 is slidably connected to the cleaning component 2. Specifically, the second arc-shaped plate 402 is slidably connected to the mounting base 202 of the cleaning component 2. The second arc-shaped plate 402 slides in cooperation with the first arc-shaped plate 401 along the circumference of the cleaning component 2.

[0195] The first arc-shaped plate 401 and the second arc-shaped plate 402 can be unfolded or stacked. In the unfolded state, at least a portion of the first arc-shaped plate 401 and / or the second arc-shaped plate 402 is located between the cleaning component and the working surface. In the stacked state, at least a portion of the first arc-shaped plate 401 and / or the second arc-shaped plate 402 is removed from the area between the cleaning component and the working surface.

[0196] This configuration, through the unfolding and stacking of the two curved plates, provides a larger covering area when unfolded, while minimizing space occupation when stacked. A limiting structure controls the relative sliding range, ensuring that the first curved plate 401 drives the second curved plate 402 along a preset trajectory. The first curved plate 401 rotates first, triggering the movement of the second curved plate 402, thus achieving orderly unfolding and stacking.

[0197] Furthermore, a limiting structure is provided between the first arc plate 401 and the second arc plate 402 to limit the relative sliding range of the two.

[0198] In this embodiment, during the process of the cleaning component 2 rising, the first rope segment 501 of the linkage component 5 can drive the first arc plate 401 to rotate. After the first arc plate 401 rotates to the maximum range allowed by the limiting structure, it drives the second arc plate 402 to rotate relative to the cleaning component 2. That is, the first arc plate 401 and the second arc plate 402 unfold, thereby blocking at least part of the working surface of the cleaning component 2.

[0199] During the descent of the cleaning component 2, the second rope segment 502 of the linkage component 5 can drive the first arc plate 401 to rotate and reset. After the second arc plate 402 rotates to the minimum range allowed by the limiting structure, it drives the second arc plate 402 to rotate relative to the cleaning component 2, that is, the first arc plate 401 and the second arc plate 402 are stacked, thereby avoiding at least part of the working surface of the cleaning component 2.

[0200] Optionally, the limiting structure includes a groove 4021 and a slider 4012. The groove 4021 is closed at both ends along its sliding direction; for example, the groove 4021 can be an oblong groove. The first arc-shaped plate 401 may be provided with the slider 4012, and the second arc-shaped plate 402 may be provided with the groove 4021 that slides with the slider 4012; conversely, the opposite is also possible.

[0201] In this embodiment, the closed ends of the slide groove 4021 can form a clear travel boundary. When the slider 4012 slides in the groove, it can strictly limit the relative sliding range of the first arc plate 401 and the second arc plate 402, ensuring the stability of the limit positions of the two when unfolded and stacked, and avoiding structural interference caused by excessive movement.

[0202] In some embodiments of this utility model, the cleaning component further includes a limiting member 9. The limiting member 9 is disposed between the cleaning component 2 and the second arc-shaped plate 402, and is configured to restrict the second arc-shaped plate 402 from sliding towards the first arc-shaped plate 401 when the first arc-shaped plate 401 and the second arc-shaped plate 402 are unfolded together.

[0203] In this embodiment, the limiting member 9 can prevent the second arc plate 402 from falling. In addition, when the first arc plate 401 and the second arc plate 402 unfold to block the cleaning member 2, the limiting member 9 can prevent the second arc plate 402 from moving towards the first arc plate 401 due to vibration or external force, thus ensuring the stability of the unfolded state.

[0204] Optionally, the limiting member 9 can be a flexible member, such as a flexible rope, flexible membrane, flexible sheet, or chain. One end of the flexible member is connected to the second arc-shaped plate 402, and the other end is connected to the mounting base 202 of the cleaning member 2. For example, when the first arc-shaped plate 401 and the second arc-shaped plate 402 are folded, the flexible member can bend or fold to a certain extent; when the first arc-shaped plate 401 and the second arc-shaped plate 402 are unfolded, the flexible member unfolds and limits the second arc-shaped plate 402.

[0205] In this embodiment, when the first arc plate 401 and the second arc plate 402 are folded, the flexible component can bend or fold along with the arc plate. Its own deformation does not occupy additional space and will not rigidly hinder the folding action, ensuring that the structure is compact in the stacked state.

[0206] When the second arc plate 402 unfolds to the preset position, the flexible component naturally straightens and tightens, limiting the sliding of the second arc plate 402 toward the first arc plate 401 by its own tension. No additional triggering structure is required, and the limiting action is completed synchronously with the unfolding process, resulting in a rapid response.

[0207] In addition, flexible components can buffer the impact force when the curved plate is unfolded, avoiding collision noise or component damage, making it especially suitable for scenarios with high requirements for quiet operation.

[0208] Of course, in other embodiments, the limiting member 9 can also be configured as a groove 4021 and a slider 4012, referring to the limiting structure.

[0209] This utility model also provides a cleaning device.

[0210] Specifically, the cleaning equipment includes the cleaning components described above.

[0211] It should be noted that the cleaning equipment includes the cleaning components and therefore all the advantages of the cleaning components mentioned above, so this will not be elaborated further.

[0212] In some embodiments provided by this utility model, the cleaning equipment is a sweeper or a floor scrubber.
