Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] Currently, cleaning equipment commonly uses rotary cleaning components such as disc mops, roller mops, or conveyor belt mops, and performs wet cleaning through humidification. However, when the equipment passes over certain obstacles such as thresholds or carpets, the wet cleaning components can easily contaminate the passageway. Therefore, existing technologies typically incorporate a retractable shielding component to cover the cleaning components when necessary.

[0003] During the shielding process, the shielding component needs to connect with the rotary cleaning component, thereby achieving linkage through the rotation of the cleaning component to complete the shielding action. However, in practical applications, it has been found that the connecting part at the end of the shielding component is prone to positional deviation during its lowering process. This can lead to alignment misalignment between the connecting part and the mating parts on the continuously operating rotary cleaning component, thus affecting the connection effect. Once the connection fails, the shielding action cannot be completed smoothly, thereby reducing the reliability and stability of the cleaning equipment. Utility Model Content

[0004] This utility model provides a cleaning device to improve the technical problem that the shielding component is prone to positional deviation during the lowering process, which leads to the failure to connect with the rotary cleaning component and thus makes the shielding action unable to be completed smoothly.

[0005] This utility model provides a cleaning device, which includes: a frame, a rotary cleaning component, a shielding component, a first suction component, and a second suction component. The rotary cleaning component is rotatably mounted on the frame and includes a first connecting component that moves in conjunction with the rotary cleaning component. The shielding component is retractably mounted on the frame and is used to shield the side of the rotary cleaning component facing the surface to be cleaned when it is lowered. The shielding component is provided with a second connecting component. The first suction component is disposed on the frame. The second suction component is disposed on the second connecting component. During the lowering process of the shielding component, the first suction component can attract the second suction component to position the second connecting component on the running path of the first connecting component, thereby enabling the second connecting component to meet and connect with the moving first connecting component. As the rotary cleaning component rotates, the first connecting component and the second connecting component in the connected state can separate the first suction component and the second suction component, thereby causing the shielding component to shield the side of the rotary cleaning component facing the surface to be cleaned.

[0006] The beneficial effects of this design are as follows: By respectively setting the first and second suction components on the second connector of the frame and the shielding component, the suction effect of the first and second suction components can actively position and stabilize the second connector on the running path of the rotary cleaning component during the lowering of the shielding component. This design can reduce the positional deviation of the second connector due to shaking or gravity during the lowering of the shielding component, ensuring its repeatability in each lowering, thereby increasing the probability of successful connection between the second connector and the moving first connector, ensuring the smooth and reliable completion of the shielding action, and ultimately improving the reliability and stability of the cleaning equipment. Simultaneously, since the first and second suction components are suction-connected, when the first connector drives the second connector, the first and second suction components can more easily separate automatically without the need for additional separation mechanisms or forced human intervention. Therefore, it simplifies the design structure and increases the automation level of the shielding action.

[0007] In one embodiment of the present invention, one of the first attracting member and the second attracting member is a magnet, and the other is a magnetic attractant; or, both the first attracting member and the second attracting member are magnets.

[0008] The beneficial effect of this design is that reliable engagement and fixation between the first and second engaging components can be achieved through the magnetic attraction between the magnet and the magnetic suction body, or between the magnets themselves. This engagement method does not rely on mechanical meshing structures and has no physical contact wear, thus resulting in a long service life, no limitation on the number of connections, and stable repeatability. This ensures that the first and second connecting components maintain a high connection success rate during long-term operation of the cleaning equipment, thereby guaranteeing the long-term stability of the blocking action and the reliability of the entire machine.

[0009] In one embodiment of the present invention, the cleaning device further includes a guide member, which is disposed on the frame and located on the outer periphery of the rotary cleaning member; along the height direction of the frame, the guide member is disposed above the first suction member, and is used to guide the second suction member to approach the first suction member during the lowering of the shielding member, so as to suction and fix it with the first suction member.

[0010] The beneficial effects of this design are as follows: By placing a guide above the first attracting member, the downward movement of the second connecting member can be pre-guided during the lowering of the blocking member. This allows the second attracting member on the second connecting member to enter the effective adsorption range of the first attracting member along a preset path, achieving adsorption with the first attracting member. This guiding effect reduces the probability of magnetic adsorption failure between the first and second attracting members due to positional deviations caused by the second connecting member during movement, thereby improving the stability and reliability of the adsorption connection.

[0011] In one embodiment of the present invention, the cleaning device further includes a guide member, which is disposed on the frame and located on the outer periphery of the rotary cleaning member; a first suction member is disposed on the guide member, and a second suction member is disposed on the side of the second connector facing the guide member; the guide member is used to guide the second suction member to approach the first suction member during the lowering of the shielding member, so as to suction and fix it with the first suction member.

[0012] The advantages of this design are as follows: By placing the first suction component on the guide component, the guide component consistently guides the second connector as it moves to the installation position of the first suction component during the lowering of the blocking component. This effectively eliminates potential alignment errors between the guide component's endpoint and the suction starting point, thereby further improving the accuracy of the suction position between the first and second suction components. Simultaneously, placing the first suction component on the guide component saves on the independent mounting structure and space required for the first suction component on the rack, resulting in a more compact overall layout. This effectively improves the utilization of the space surrounding the rack and facilitates the miniaturization and lightweight design of the cleaning equipment.

[0013] In one embodiment of the present invention, the guide member includes a first guide surface on the side facing the rotary cleaning member. Along the height direction of the frame, 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, and the first guide surface gradually extends toward the rotary cleaning member along the direction from the starting end to the extension end.

[0014] The beneficial effects of this design are as follows: The first guide surface provides a controllable movement trajectory for the second connector, allowing it to slide smoothly along a predetermined path during lowering. This ensures that as the second connector gradually approaches the installation position of the first suction component, it simultaneously approaches the first connector on the rotary cleaning component. This accurately guides and positions the second connector on the rotary path of the first connector, creating favorable conditions for a reliable subsequent connection. Simultaneously, guided by the first guide surface, the second suction component can enter the effective adsorption range of the first suction component with a better posture and smaller positional deviation. This improves the alignment accuracy between the first and second connectors, thereby increasing the success rate of their connection.

[0015] In one embodiment of the present invention, the first suction member is disposed on the side of the first guide surface opposite to the rotary cleaning member; during the lowering process of the shielding member, the first suction member suctions and fixes the second connecting member to the first guide surface.

[0016] The beneficial effects of this design are as follows: By placing the first suction element on the first guide surface, the first guide surface can integrate both guiding and magnetic adsorption functions. In this structure, the second connector can simultaneously complete path guidance and adsorption positioning as it slides along the first guide surface, and the final adsorption position of the second and first suction elements is closer to the rotary cleaning component. When the second connector is adsorbed and fixed to the first guide surface, its position and orientation are constrained by the guide surface, effectively suppressing any possible offset or shaking after adsorption, thereby significantly improving the positional accuracy and connection stability when the second and first connectors are docked.

[0017] In one embodiment of the present invention, the second connector is provided with a first mounting cavity, and the second suction member is accommodated in the first mounting cavity; when the first suction member and the second suction member are attracted and fixed together, the second suction member abuts against the first guide surface.

[0018] The beneficial effects of this design are as follows: when the first and second suction components are engaged and fixed, the second suction component abuts against the first guide surface. This structural design ensures that the installation position of the first suction component does not affect the continuous flatness of the first guide surface. Therefore, during the engagement of the first and second suction components, the first guide surface can maintain a stable and precise guiding function. This effectively reduces the adverse effects of the first suction component's placement on the guiding accuracy of the first guide surface, thereby ensuring the reliability and consistency of the first guide surface's guidance.

[0019] In one embodiment of the present invention, the guide member on the side facing the rotary cleaning member further includes a second guide surface. Along the height direction of the frame, the second guide surface is disposed above the first guide surface and connected to the starting end. During the lowering of the shielding member, the second connecting member can slide along the second guide surface to guide the second connecting member closer to the first guide surface.

[0020] The beneficial effects of this design are as follows: By setting a second guide surface connected to the first guide surface above it, a continuous segmented guide path can be formed on the guide component. During the lowering process of the shielding component, the second guide surface, as the initial guide segment, can perform preliminary positioning and motion trajectory constraint on the second connector, which is located at a higher position, allowing it to smoothly transition to the first guide surface. This structure can reduce the large attitude deviation or positional deviation of the second connector due to the lack of guidance during the initial lowering stage, thereby ensuring that the second connector can enter the first guide surface area with a predetermined attitude and position. This provides favorable conditions for subsequent precise docking with the first connector, thus improving the connection reliability between the first and second connectors.

[0021] In one embodiment of the present invention, the guide extends along the height direction of the frame, and the end of the guide away from the first guide surface is fixed to the frame; when the second connector slides along the first guide surface and abuts against the guide under the drive of the first connector, the guide can undergo elastic deformation to drive the first guide surface away from the rotary cleaning component.

[0022] The beneficial effects of this design are as follows: When the second connector slides along the first guide surface and abuts against the guide under the influence of the first connector, the guide can undergo elastic deformation, causing the first guide surface to move away from the rotary cleaning component. This action constitutes a dynamic adjustment mechanism for the docking distance between the first and second connectors. Based on this dynamic adjustment mechanism, the final positioning of the second connector on the guide can be preset to be closer to the first connector, thereby ensuring that the two maintain an appropriate abutment force during the docking process. The presence of this abutment force ensures a stable connection between the first and second connectors. Simultaneously, through the aforementioned dynamic adjustment mechanism, dimensional fluctuations caused by manufacturing tolerances or assembly errors can be effectively absorbed, reducing the risk of excessive docking gaps, thus improving the docking accuracy and connection success rate between the first and second connectors.

[0023] In one embodiment of the present invention, the guide extends along the height direction of the frame, and the end of the guide away from the first guide surface is rotatably connected to the frame; when the second connector slides along the first guide surface and abuts against the guide under the drive of the first connector, the guide can rotate relative to the frame to drive the first guide surface away from the rotary cleaning component.

[0024] The beneficial effects of this design are as follows: When the second connector slides along the first guide surface and abuts against the guide under the influence of the first connector, the guide can rotate relative to the frame, causing the first guide surface to move away from the rotary cleaning component. This action constitutes a dynamic adjustment mechanism for the docking distance between the first and second connectors. Based on this dynamic adjustment mechanism, the final positioning of the second connector on the guide can be preset to be closer to the first connector, thereby ensuring that the two maintain an appropriate abutment force during the docking process. The presence of this abutment force ensures a stable connection between the first and second connectors. Simultaneously, the aforementioned dynamic adjustment mechanism effectively absorbs dimensional fluctuations caused by manufacturing tolerances or assembly errors, reducing the risk of excessive docking gaps, and thus improving the docking accuracy and connection success rate between the first and second connectors.

[0025] In one embodiment of the present invention, an elastic element is provided between the guide and the frame. One end of the elastic element acts on the guide and the other end acts on the frame. When the guide rotates due to the abutment of the second connecting member, the elastic element is configured to store potential energy through elastic deformation to drive the guide to rotate and reset.

[0026] The beneficial effects of this design are as follows: By incorporating an elastic element that stores potential energy as the guide rotates, the stored energy is released when the resisting force disappears, driving the guide to automatically return to its initial working position. This mechanism ensures that the guide is in the preset position before each lowering of the blocking element, providing a reliable guarantee for continuous operation. Simultaneously, the elastic element also mitigates the impact between the guide and the second connecting element, thereby reducing vibration, operating noise, and component wear generated during their contact.

[0027] In one embodiment of this utility model, the elastic element is a torsion spring; the guide element is rotatably connected to the frame via a rotating shaft, the torsion spring is installed on the rotating shaft, and the two lever arms of the torsion spring abut against the frame and the guide element respectively.

[0028] The advantages of this design are as follows: Using a torsion spring as the reset element, with its two lever arms abutting against the surfaces of the frame and guide components respectively. This design eliminates the need for complex fixing structures, simplifying the assembly process of the elastic element. Furthermore, the physical limiting effect of the lever arms reduces the probability of slippage or misalignment of the elastic element during operation. In addition, the torsion spring primarily withstands torsional deformation during movement; its material exhibits high fatigue strength and excellent wear resistance, enabling it to withstand frequent rotational reset conditions and maintain a stable elastic restoring force over a long period.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model 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 this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] 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 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.

[0049] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present 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 present invention.

[0050] Please see Figures 1 to 14 The cleaning device of this invention, by respectively setting a first suction member 101 and a second suction member 102 on the second connecting member 311 of the frame 10 and the shielding member 31, can utilize the suction effect of the first suction member 101 and the second suction member 102 to actively position and stabilize the second connecting member 311 on the running path of the rotary cleaning member 20 during the lowering of the shielding member 31. This design can reduce the positional deviation of the second connecting member 311 caused by shaking or gravity during the lowering of the shielding member 31, ensuring its repeatability in each lowering, thereby increasing the probability of successful connection between the second connecting member 311 and the moving first connecting member 21, ensuring the smooth completion of the shielding action, and ultimately improving the reliability and stability of the cleaning device.

[0051] Please see Figures 1 to 6 The cleaning device includes: a frame 10, a rotary cleaning component 20, a shielding component 31, a first suction component 101, and a second suction component 102. 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.

[0052] 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.

[0053] The rotary cleaning component 20 is rotatably mounted on the frame 10. The rotatable mounting method is not limited; for example, it can be a cleaning device that also includes a rotary mechanism. The fixed end of the rotary mechanism is located on the frame 10, and the drive end of the rotary mechanism is connected to the rotary cleaning component 20. The operation of the rotary mechanism drives the rotary cleaning component 20 to rotate relative to the frame 10. For details, please refer to [link to relevant documentation]. Figure 7 In this embodiment, the cleaning equipment also includes an inner support mechanism 40, which is mounted on the frame 10. 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, thus performing the cleaning operation. The inner support mechanism 40 can be formed using different support structures such as a roller type or a track type, as long as it can drive the rotary cleaning component 20 to rotate for cleaning. Specifically, if the inner support mechanism 40 is a roller type structure, the rotary cleaning component 20 fitted around its outer periphery can form a roller-type wiping cloth structure. If the inner support mechanism 40 is a track-type support structure, the rotary cleaning component 20 fitted around its outer periphery can form a track-type wiping cloth structure.

[0054] Optionally, in this embodiment, as Figure 7 As shown, the inner support mechanism 40 is a tracked support structure, and the rotary cleaning component 20 is fitted onto 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 fitted onto 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.

[0055] 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. This embodiment does not limit this.

[0056] The cleaning equipment also includes a shielding mechanism 30, which includes a shielding member 31 that is retractably mounted on the frame 10. Specifically, the shielding member 31 has a first state and a second state. Figure 7 As shown, in the first state, the shielding member 31 is in a retracted state, exposing the side of the rotary cleaning member 20 facing the surface to be cleaned, allowing the rotary cleaning member 20 to perform normal cleaning operations. Figure 8 As shown, in the second state, the shielding member 31 is in a lowered and unfolded state, and can shield the side of the rotating cleaning member 20 facing the surface to be cleaned, so as to isolate the rotating cleaning member 20 from the surface to be cleaned.

[0057] 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 further include a roller and a drive assembly. The roller is rotatably mounted on the mounting base, 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. 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, 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.

[0058] Please see Figure 2 and Figure 3 The rotary cleaning component 20 includes a first connecting member 21 that moves in conjunction with the rotary cleaning component 20, and the shielding member 31 includes a second connecting member 311. The first connecting member 21 and the second connecting member 311 are connected (e.g., Figure 2 (as shown) and out-of-state (as shown) Figure 3 (As shown). 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 the rotation of the rotary cleaning component 20.

[0059] 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.

[0060] 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. 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, thus completing the shielding action of the shielding member 31 on the rotary cleaning member 20. 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 runs 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 will disengage, and the rotary cleaning member 20 can resume normal operation, preparing for normal cleaning work.

[0061] 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 absorber. Optionally, in this embodiment, please refer to... Figure 2 The first connector 21 is provided with a slot 211, and the second connector 311 is provided with a hook 3112. The connection between the first connector 21 and the second connector 311 is achieved by the hook 3112 engaging with the slot 211.

[0062] The first suction member 101 is disposed on the frame 10. Specifically, the first suction member 101 can be directly disposed on the frame 10, or it can be disposed on other components fixedly connected to the frame 10. The way the first suction member 101 is disposed on the frame 10 is not limited. For example, the frame 10 can be provided with a mounting cavity, and the first suction member 101 can be accommodated in the mounting cavity to achieve fixation with the frame 10. Alternatively, the first suction member 101 can be directly fixed to the frame 10 by bolts or snap-fit. The specific shape of the first suction member 101 is not limited, and it can be cylindrical, cuboid, polygonal, etc.

[0063] Please see Figure 5 The second suction member 102 is disposed on the second connector 311, and the disposal method is not limited. For example, the second suction member 102 can be embedded in the second connector 311, or it can be fixedly connected to the second connector 311 by bolts or the like.

[0064] During the lowering of the shielding member 31, the first suction member 101 can attract the second suction member 102 to position the second connecting member 311 on the running path of the first connecting member 21, thereby enabling the second connecting member 311 to meet and connect with the moving first connecting member 21. As the rotary cleaning member 20 rotates, the first connecting member 21 and the second connecting member 311 in the connected state can separate the first suction member 101 from the second suction member 102, thereby causing the shielding member 31 to block the rotary cleaning member 20 from the side facing the surface to be cleaned.

[0065] Specifically, the default initial position of the shielding member 31 is the retracted position, at which time the shielding member 31 and the second connecting member 311 are located above the first suction member 101. When the shielding member 31 begins to descend, it moves towards the first suction member 101 under the action of gravity, and drives the second suction member 102 to move down synchronously. When the second suction member 102 enters the effective range of the first suction member 101, the two attract each other. The first suction member 101 guides and fixes the second suction member 102 to the installation position of the first suction member 101, thereby positioning the second connecting member 311 on the running path of the first connecting member 21 and in a docking posture that can receive the first connecting member 21. Subsequently, when the rotary cleaning member 20 drives the first connecting member 21 to this position, the first connecting member 21 and the second connecting member 311 are connected. Next, the rotary cleaning component 20 continues to operate, pulling the second connecting component 311 and the blocking component 31 to continue to lower through the first connecting component 21 until the blocking component 31 completely covers the side of the rotary cleaning component 20 facing the surface to be cleaned, thus completing the blocking action.

[0066] During this process, after the second connector 311 is connected to the first connector 21, the second connector 311 will gradually move away from the installation position of the first suction member 101 as the rotary cleaning member 20 rotates, so that the suction between the first suction member 101 and the second suction member 102 is naturally released, and the two are separated.

[0067] In this embodiment, by respectively setting a first suction member 101 and a second suction member 102 on the second connecting member 311 of the frame 10 and the shielding member 31, the suction effect of the first suction member 101 and the second suction member can be used to actively position and stabilize the second connecting member 311 on the running path of the rotary cleaning member 20 during the lowering of the shielding member 31. This design can reduce the positional deviation of the second connecting member 311 caused by shaking or gravity during the lowering of the shielding member 31, ensuring its repeatability in each lowering, thereby increasing the probability of successful connection between the second connecting member 311 and the moving first connecting member 21, ensuring the smooth completion of the shielding action, and ultimately improving the reliability and stability of the cleaning equipment operation. Meanwhile, since the first suction member 101 and the second suction member 102 are connected by suction, when the first connecting member 21 drives the second connecting member 311 to move, the first suction member 101 and the second suction member 102 can be more easily separated automatically without the need for additional separation mechanism or forced human intervention. Therefore, the design structure can be simplified and the degree of automation of the blocking action process can be improved.

[0068] It should be noted that, in the above embodiments, there are various ways to implement the number and position of the first connector 21, the second connector 311, the first suction member 101, and the second suction member 102, which will be described below through different embodiments.

[0069] In one embodiment, first connecting members 21 are provided on both sides along the length direction of the rotary cleaning member 20. Correspondingly, second connecting members 311 are also provided on both sides along the length direction (consistent with the length direction of the rotary cleaning member 20). The first connecting member 21 on each side can be connected to the second connecting member 311 on the same side. In this case, only the first suction member 101 and the second suction member 102 are provided on one side of the length direction of the rotary cleaning member 20 to achieve precise positioning of the second connecting member 311 on that side. The second connecting member 311 on the other side is connected to the corresponding first connecting member 21 through mechanical cooperation or follow-up.

[0070] In another embodiment, the rotary cleaning component 20 and the shielding component 31 are respectively provided with a first connecting component 21 and a second connecting component 311 on both sides of the length direction. Correspondingly, a first suction component 101 and a second suction component 102 are also provided on both sides of the frame 10, which are used to position the second connecting components 311 on both sides when the shielding component 31 is lowered, thereby increasing the probability of successful connection between the first connecting component 21 and the second connecting component 311 on both sides.

[0071] In another embodiment, along the length of the rotary cleaning member 20, a first connector 21 is provided only on one side. Correspondingly, the shielding member 31 also has a second connector 311 corresponding to the first connector 21 on only one side. A first suction member 101 and a second suction member 102 are provided on this side to position the second connector 311 on that side, thereby increasing the probability of successful connection between the first connector 21 and the second connector 311 on that side.

[0072] Please see Figure 9 and Figure 10 In one embodiment of this utility model, the rotary cleaning component 20 includes a cleaning component body 201 and an annular portion 202. The cleaning component body 201 is used to clean the surface to be cleaned, and the annular portion 202 is disposed at the end of the cleaning component body 201. A first connecting member 21 is connected to the annular portion 202. The rotary cleaning component 20 also includes a water-absorbing layer 203, which is disposed around the outer periphery of the cleaning component body 201. The water-absorbing layer 203 can contact 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.

[0073] The arrangement of the absorbent layer 203 varies in different embodiments. In one embodiment, the absorbent layer 203 is disposed only around the outer periphery of the cleaning component body 201. In another embodiment, please refer to... Figure 10 The absorbent layer 203 not only surrounds the outer periphery of the cleaning component body 201, but also extends to cover the area of ​​the annular portion 202 where the first connecting member 21 is not located. This design allows the rotary cleaning component 20 to achieve a larger cleaning area in the length direction, thereby improving cleaning efficiency.

[0074] Please see Figure 5 and Figure 6 In one embodiment of the present invention, one of the first attracting member 101 and the second attracting member 102 is a magnet, and the other is a magnetic attractant; or, both the first attracting member 101 and the second attracting member 102 are magnets, and the polarity of the first attracting member 101 is opposite to that of the second attracting member 102.

[0075] Specifically, in one embodiment, the first attracting member 101 is a magnet, and the second attracting member 102 is a magnetic attractor (such as a magnetically conductive material like iron, steel, or silicon steel). The first attracting member 101 is attracted and fixed to the second attracting member 102 through the attraction between the magnet and the magnetic attractor.

[0076] In another embodiment, the first attracting member 101 is a magnetic attractor, and the second attracting member 102 is a magnet. In this way, the first attracting member 101 can also be attracted and fixed to the second attracting member 102 through the attraction between the magnet and the magnetic attractor.

[0077] In other embodiments, the first attracting member 101 is a magnet, and the second attracting member 102 is also a magnet. Furthermore, the magnetic polarities of the first attracting member 101 and the second attracting member 102 are opposite. Thus, the first attracting member 101 and the second attracting member 102 can be attracted and fixed together by two magnets with opposite polarities.

[0078] It should be noted that the type of magnet is not limited in this embodiment; the magnet can be a permanent magnet or an electromagnet. Preferably, in this embodiment, the magnet is a permanent magnet. Compared with electromagnets, which require electricity and control circuitry, permanent magnets provide a constant magnetic field based on the inherent properties of the material, eliminating the need for external power supply and control. This simplifies the overall structure and control system of the cleaning equipment, thereby reducing the failure rate during operation and improving operational stability and reliability.

[0079] In this embodiment, reliable attraction and fixation between the first attraction member 101 and the second attraction member 102 can be achieved through magnetic attraction between the magnet and the magnetic attractor, or through magnetic attraction between magnets. This attraction method does not rely on mechanical meshing structures and has no physical contact wear, thus resulting in a long service life, no limitation on the number of connections, and stable repeatability. This ensures that the first connector 21 and the second connector 311 can maintain a high connection success rate during long-term operation of the cleaning equipment, thereby guaranteeing the stability of the blocking action and the reliability of the entire machine.

[0080] In one embodiment of this utility model, the cleaning device further includes a guide member 12, which is disposed on the frame 10 and located on the outer periphery of the rotary cleaning member 20. The guide member 12 may be directly mounted on the frame 10 or mounted on other components connected to the frame 10. Along the height direction of the frame 10, the guide member 12 is disposed above the first suction member 101, and is used to guide the second suction member 102 to approach the first suction member 101 during the lowering of the shielding member 31, so as to suction and fix it with the first suction member 101.

[0081] Specifically, the guide member 12 and the first suction member 101 are both disposed on the frame 10 and installed at different positions on the frame 10. During the lowering process of the shielding member 31, the second connecting member 311 first contacts the guide member 12 and, guided by the guide member 12, approaches the position of the first suction member 101, so that the second suction member 102 can reliably engage with the first suction member 101. In this embodiment, the specific structural form of the guide member 12 can be selected according to actual needs. For example, the guide member 12 can be a groove, a protrusion, etc., as long as it can guide the movement of the second connecting member 311 during the lowering process of the shielding member 31, so that the second suction member 102 can approach the first suction member 101 and engage and fix with the first suction member 101.

[0082] In this embodiment, by providing a guide 12 above the first attracting member 101, the downward movement of the second connecting member 311 can be pre-guided during the lowering of the blocking member 31. This allows the second attracting member 102 on the second connecting member 311 to enter the effective adsorption range of the first attracting member 101 along a preset path, achieving adsorption with the first attracting member 101. This guiding effect can reduce the probability of magnetic adsorption failure between the first attracting member 101 and the second attracting member 102 due to positional deviation of the second connecting member 311 during movement, thereby improving the stability and reliability of the adsorption connection.

[0083] Please see Figure 6 , Figure 8 and Figure 9 In one embodiment of this utility model, the cleaning device further includes a guide member 12, which is disposed on the frame 10 and located on the outer periphery of the rotary cleaning member 20. A first suction member 101 is disposed on the guide member 12, and a second suction member 102 is disposed on the side of the second connecting member 311 facing the guide member 12. The guide member 12 is used to guide the second suction member 102 close to the first suction member 101 during the lowering of the shielding member 31, so as to suction and fix it with the first suction member 101. The specific manner in which the first suction member 101 is disposed on the guide member 12 is not limited. For example, the first suction member 101 can be embedded in the guide member 12, or it can be fixedly installed on the guide member 12 by fasteners such as bolts, or the guide member 12 can be provided with a mounting cavity, and the first suction member 101 can be fixedly installed in the mounting cavity.

[0084] Specifically, please refer to Figure 6 Along the height direction of the frame 10, one side of the guide member 12 extends upward and at least partially into the lowering path of the second connector 311, serving to initially guide and limit the descent of the second connector 311. The other side of the guide member 12 extends downward and approaches the rotary cleaning component 20, with the first suction member 101 positioned on the side of the guide member 12 approaching the rotary cleaning component 20. During the lowering of the shielding component 31, the second connector 311 first contacts the area of ​​the guide member 12 above the first suction member 101, and moves under the guidance of this area to the installation position of the first suction member 101, so that the second suction member 102 can reliably engage with the first suction member 101.

[0085] In this embodiment, by placing the first suction member 101 on the guide member 12, the guide member 12 consistently guides the second connecting member 311 as it moves to the installation position of the first suction member 101 when the blocking member 31 is lowered. This effectively eliminates potential alignment errors between the end point of the guide member 12 and the starting point of suction, thereby further improving the accuracy of the suction position between the first suction member 101 and the second suction member 102. Simultaneously, by placing the first suction member 101 on the guide member 12, the independent installation structure and space of the first suction member 101 on the frame 10 are saved, resulting in a more compact overall layout and effectively improving the utilization rate of the space surrounding the frame 10, which is beneficial for the miniaturization and lightweight design of the cleaning equipment.

[0086] Please see Figure 6 In one embodiment of this utility model, 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 frame 10, 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. The first guide surface 121 gradually extends towards 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 slides along the first guide surface 121, thereby gradually approaching the installation position of the first suction member 101 and simultaneously approaching the rotary cleaning member 20 and the first connecting member 21 on it, so as to achieve the positioning of the second connecting member 311 on the rotation path of the first connecting member 21.

[0087] The specific structural form of the first guide surface 121 is not limited, for example, it can be a sloped structure, an arc surface structure, etc. 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 towards the rotary cleaning component 20 from the starting end 1211 to the extension end 1212.

[0088] In this embodiment, the first guide surface 121 provides a controllable movement trajectory for the second connector 311, allowing it to slide smoothly along a predetermined path during lowering. This ensures that the second connector 311 approaches the first connector 21 on the rotary cleaning component 20 simultaneously as it gradually approaches the installation position of the first suction component 101. This accurately guides and positions the second connector 311 on the rotation path of the first connector 21, creating favorable conditions for subsequent reliable connection. Simultaneously, guided by the first guide surface 121, the second suction component 102 can enter the effective adsorption range of the first suction component 101 with a better posture and smaller positional deviation. This improves the alignment accuracy between the first connector 21 and the second connector 311, thereby increasing the success rate of connection between them.

[0089] Based on the above embodiments, the first suction member 101 may be disposed on the first guide surface 121 of the guide member 12, or it may be disposed at other positions on the guide member 12. Optionally, please refer to Figure 5 and Figure 6 In one embodiment of the present invention, the first suction member 101 is disposed on the side of the first guide surface 121 opposite to the rotary cleaning member 20. During the lowering process of the shielding member 31, the first suction member 101 suctions and fixes the second connecting member 311 onto the first guide surface 121.

[0090] The specific location of the first suction member 101 on the first guide surface 121 is not limited. In one embodiment, the first suction member 101 may be embedded in the side of the first guide surface 121 opposite to the rotary cleaning member 20, and the adsorption surface of the first suction member 101 may be flush with or slightly lower than the first guide surface 121. In another embodiment, the first suction member 101 may be completely located on the side of the first guide surface 121 opposite to the rotary cleaning member 20, that is, the adsorption surface of the first suction member 101 may not be exposed on the side of the first guide surface 121 facing the rotary cleaning member 20. In addition, the first suction member 101 may be disposed at the starting end 1211 of the first guide member 12, or at the extension end 1212, or in the intermediate region between the starting end 1211 and the extension end 1212. The specific location needs to be determined according to the relative size between the first suction member 101 and the first guide surface 121.

[0091] Optionally, please refer to Figure 5 In this embodiment, the guide member 12 is provided with a plurality of claws 123 on the side of the first guide surface 121 opposite to the rotary cleaning member 20. The plurality of claws 123 surround to form a second mounting cavity 124, and the first suction member 101 is fixedly installed in the second mounting cavity 124.

[0092] In this embodiment, by placing the first suction member 101 on the side of the first guide surface 121 opposite to the rotary cleaning member 20, the guide member 12 can integrate both guiding and magnetic adsorption functions at the position of the first guide surface 121. With this structure, the second connector 311 can simultaneously complete path guidance and adsorption positioning during its sliding along the first guide surface 121, and the adsorption position of the second suction member 102 and the first suction member 101 can be closer to the rotary cleaning member 20. When the second connector 311 is adsorbed and fixed to the first guide surface 121, its position and orientation are constrained by the physical constraint of the first guide surface 121, effectively suppressing possible offset or shaking after adsorption, thereby improving the positional accuracy and connection stability when the second connector 311 and the first connector 21 are docked.

[0093] Please see Figure 5 and Figure 6 In one embodiment of the present invention, the second connector 311 is provided with a first mounting cavity 3111, and the second suction member 102 is accommodated in the first mounting cavity 3111. When the first suction member 101 and the second suction member 102 are attracted and fixed together, the second suction member 102 abuts against the first guide surface 121.

[0094] Specifically, please refer to Figure 6 The second connector 311 includes a main body 3113 and a connecting part 3114. The main body 3113 is fixedly connected to the shielding member 31, and the connecting part 3114 is used to connect with the first connector 21. A first mounting cavity 3111 is disposed in the main body 3113. The first mounting cavity 3111 has an opening facing the first guide surface 121. The adsorption surface of the second suction member 102 is exposed from the opening to contact the first guide surface 121 and to be attracted to the first suction member 101 mounted on the side of the first guide surface 121 away from the rotary cleaning member 20. The adsorption surface of the second suction member 102 can be flush with the opening, or it can be higher or lower than the opening. As long as the required adsorption force is ensured between the second suction member 102 and the first suction member 101, it is acceptable.

[0095] In this embodiment, when the first suction member 101 and the second suction member 102 are attracted and fixed together, the second suction member 102 abuts against the first guide surface 121. This structural design indicates that the installation position of the first suction member 101 will not affect the continuous flatness of the first guide surface 121. Therefore, during the attraction process of the first suction member 101 and the second suction member 102, the first guide surface 121 can always maintain a stable and accurate guiding function. This effectively reduces the adverse effects of the setting of the first suction member 101 on the guiding accuracy of the first guide surface 121, thereby ensuring the reliability and consistency of the guiding of the first guide surface 121.

[0096] Please see Figure 6In one embodiment of this utility model, 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 frame 10, the second guide surface 122 is disposed above the first guide surface 121 and connected to the starting end 1211. During the lowering process 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 closer to the first guide surface 121. The second guide surface 122 can be a vertical surface structure, a bent surface structure, or a curved surface structure, as long as it can guide the downward movement of the second connecting member 311.

[0097] In this embodiment, by providing a second guide surface 122 connected to the first guide surface 121 above it, a continuous segmented guide path can be formed on the guide member 12. During the lowering process of the shielding member 31, the second guide surface 122 serves as the initial guide segment, enabling the second connecting member 311, which is at a higher position, to be initially positioned and its movement trajectory constrained, allowing it to smoothly transition to the first guide surface 121. This structure can reduce the large attitude deviation or positional deviation of the second connecting member 311 due to lack of guidance during the initial lowering stage, thereby ensuring that the second connecting member 311 can enter the area of ​​the first guide surface 121 in a predetermined attitude and position, providing favorable conditions for subsequent precise docking with the first connecting member 21, and thus improving the reliability of the connection between the first connecting member 21 and the second connecting member 311.

[0098] Please see Figure 6 In one embodiment of this utility model, the guide member 12 extends along the height direction of the frame 10, and the end of the guide member 12 away from the first guide surface 121 is fixed to the frame 10. The fixed connection method includes, but is not limited to, fastener connection such as bolts, snap-fit ​​connection, etc. When the second connecting member 311 slides along the first guide surface 121 and abuts against the guide member 12 under the drive of the first connecting member 21, the guide member 12 can undergo elastic deformation to drive the first guide surface 121 away from the rotary cleaning member 20.

[0099] Specifically, in one embodiment, the guide member 12 may be made of an engineering plastic with a certain degree of elasticity. When the second connector 311 slides along the first guide surface 121 and abuts against it under the action of the first connector 21, the guide member 12 can be compressed and elastically deformed under the action of the abutment force, thereby driving the first guide surface 121 as a whole to move away from the rotary cleaning component 20, thereby realizing the displacement of the first guide surface 121 away from the rotary cleaning component 20. In another embodiment, the guide member 12 may also be made of a metal sheet structure (such as copper sheet, carbon steel sheet, etc.). When the second connector 311 slides along the first guide surface 121 and abuts against the first guide surface 121 under the action of the first connector 21, the metal sheet can be elastically bent under the action of the abutment force, that is, it bends laterally towards the side away from the rotary cleaning component 20, thereby realizing the displacement of the first guide surface 121 away from the rotary cleaning component 20.

[0100] In this embodiment, when the second connector 311 slides along the first guide surface 121 and abuts against the guide 12 under the action of the first connector 21, the guide 12 can undergo elastic deformation, causing the first guide surface 121 to move away from the rotary cleaning component 20. This action constitutes a dynamic adjustment mechanism for the docking distance between the first connector 21 and the second connector 311. Based on this dynamic adjustment mechanism, the final positioning position of the second connector 311 on the guide 12 can be preset to be closer to the first connector 21, thereby ensuring that the two always maintain an appropriate abutment force during the docking process. The presence of this abutment force can ensure a stable connection between the first connector 21 and the second connector 311. At the same time, through the above-mentioned dynamic adjustment mechanism, dimensional fluctuations caused by manufacturing tolerances or assembly errors can be effectively absorbed, reducing the risk of excessive docking gap, thereby improving the docking accuracy and connection success rate between the first connector 21 and the second connector 311.

[0101] Please see Figure 6 In one embodiment of this utility model, the guide member 12 extends along the height direction of the frame 10, and the end of the guide member 12 away from the first guide surface 121 is rotatably connected to the frame 10. The rotatable connection method includes, but is not limited to, a shaft connection. When the second connecting member 311 slides along the first guide surface 121 and abuts against the guide member 12 under the drive of the first connecting member 21, the guide member 12 can rotate relative to the frame 10, so as to drive the first guide surface 121 away from the rotary cleaning member 20.

[0102] Specifically, when the second connector 311 slides along the first guide surface 121 under the action of the first connector 21, the second connector 311 applies a resisting force to the first guide surface 121 in a direction away from the rotary cleaning component 20. Under the action of this resisting force, the guide component 12 can rotate around its connection point with the frame 10, thereby causing the first guide surface 121 to move as a whole in a direction away from the rotary cleaning component 20.

[0103] It should be noted that, to further improve the automatic reset performance of the guide member 12, an elastic reset member or a drive mechanism can also be provided between the guide member 12 and the frame 10. When the second connector 311 disengages from the guide member 12, the elastic reset member or drive mechanism can push the guide member 12 to rotate in the opposite direction, so that it automatically returns to its initial working position, in preparation for the next connection process between the second connector 311 and the first connector 21.

[0104] In this embodiment, when the second connector 311 slides along the first guide surface 121 and abuts against the guide 12 under the drive of the first connector 21, the guide 12 can rotate relative to the frame 10, thereby driving the first guide surface 121 to move away from the rotary cleaning component 20. This action constitutes a dynamic adjustment mechanism for the docking distance between the first connector 21 and the second connector 311. Based on this dynamic adjustment mechanism, the final positioning position of the second connector 311 on the guide 12 can be preset to be closer to the first connector 21, thereby ensuring that the two always maintain an appropriate abutment force during the docking process. The presence of this abutment force can ensure a stable connection between the first connector 21 and the second connector 311. At the same time, through the above-mentioned dynamic adjustment mechanism, dimensional fluctuations caused by manufacturing tolerances or assembly errors can be effectively absorbed, reducing the risk of excessive docking gap, thereby improving the docking accuracy and connection success rate between the first connector 21 and the second connector 311.

[0105] Please see Figures 11 to 14 In one embodiment of this utility model, an elastic element 50 is provided between the guide member 12 and the frame 10. One end of the elastic element 50 acts on the guide member 12, and the other end acts on the frame 10. When the guide member 12 rotates due to abutment by the second connecting member 311, the elastic element 50 is configured to store potential energy through elastic deformation to drive the guide member 12 to rotate and reset. The elastic element 50 can be a compressive elastic element, a tensile elastic element, a torsion spring, or other elastic elements, and its specific type can be adaptively selected according to the installation space, reset torque requirements, and structural layout.

[0106] Specifically, when the guide member 12 rotates due to the contact with the second connecting member 311, the elastic member 50 undergoes elastic deformation and stores elastic potential energy. When the first connecting member 21 drives the second connecting member 311 to continue running and gradually disengage from the guide member 12, the elastic member 50 releases its elastic potential energy and drives the guide member 12 to rotate in the opposite direction, causing it to automatically reset to its initial position.

[0107] It should be noted that when the guide member 12 is in the initial position, the elastic member 50 is configured to have a certain preload, which can stably hold the guide member 12 in the preset working position of the frame 10.

[0108] In this embodiment, an elastic element 50 is provided, which stores potential energy when the guide 12 rotates. When the contact force disappears, the elastic element 50 releases the stored energy, thereby driving the guide 12 to automatically return to its initial working position. This mechanism ensures that the guide 12 is in a preset position before each lowering of the blocking element 31, providing a reliable guarantee for continuous operation. Simultaneously, the elastic element 50 also buffers the contact impact between the guide 12 and the second connecting element 311, thereby reducing vibration, operating noise, and component wear generated during the contact between the second connecting element 311 and the guide 12.

[0109] Furthermore, when the first connector 21 drives the second connector 311 to slide along the first guide surface 121, the second connector 311 applies a resisting force to the guide 12, causing the guide 12 to rotate away from the rotary cleaning component 20. Simultaneously, the elastic element 60 deforms and stores elastic potential energy, which is then converted into a thrust that pushes the guide 12 and the second connector 311 to rotate towards the rotary cleaning component 20. Under the combined action of the resisting force and the thrust, dynamic balance can be achieved during the rotation of the guide 12 and the second connector 311, ensuring that the second connector 311 maintains a good contact with the first connector 21 at all times. Therefore, the elastic element 60 can also dynamically adjust the mating distance between the first connector 21 and the second connector 311, thereby improving the success rate of the mating of the first connector 21 and the second connector 311. Optionally, please refer to... Figures 12 to 14 In one embodiment of this utility model, the elastic element 50 is a torsion spring, the guide element 12 is rotatably connected to the frame 10 via a rotating shaft 60, the torsion spring is installed on the rotating shaft 60, and the two lever arms of the torsion spring respectively abut against the frame 10 and the guide element 12. The rotating shaft 60 and the elastic element 50 can be installed on the outside of the frame 10 or disposed in the inner cavity of the frame 10.

[0110] Specifically, please refer to Figure 12In this embodiment, the frame 10 has two opposing protrusions 103, and the rotating shaft 60 is rotatably supported on the two protrusions 103. The frame 10 has a through hole 104, and one end of the guide member 12 away from the first guide surface 121 passes through the through hole 104 and is fixedly connected to the rotating shaft 60. A torsion spring is sleeved on the rotating shaft 60, and the two arms of the torsion spring respectively abut against the outer wall of the frame 10 and the surface of the guide member 12 away from the rotary cleaning component 20. When the guide member 12 rotates relative to the frame 10, it causes the two arms of the torsion spring to rotate relative to each other, causing the torsion spring to undergo elastic deformation, thereby storing or releasing the elastic properties of the elastic component 50.

[0111] It should be noted that, to improve the stability of the contact between the lever arm of the torsion spring and the frame 10, optionally, in one embodiment, please refer to... Figure 12 The frame 10 may also be provided with a snap-fit ​​groove 105, in which the stress arm of the torsion spring is snapped into the snap-fit ​​groove 106. This structure can limit the range of motion of the stress arm through the snap-fit ​​groove 106, thereby limiting the positional change of the stress arm relative to the frame 10 during the rotation of the guide member 12, reducing operating deviation, and thus ensuring that the torsion spring always maintains a stable contact state and reliable torque output during operation.

[0112] In this embodiment, a torsion spring is used as the reset element, with its two lever arms abutting against the surfaces of the frame 10 and the guide member 12, respectively. This design eliminates the need for a complex fixing structure, simplifying the assembly process of the elastic element 50. Furthermore, the physical limiting effect of the lever arms reduces the probability of slippage or misalignment of the elastic element 50 during operation. In addition, the torsion spring primarily withstands torsional deformation during movement; its material exhibits high fatigue strength and excellent wear resistance, enabling it to adapt to frequent rotational reset conditions and maintain a stable elastic restoring force over a long period.
