Description

Technical Field

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

[0002] Cleaning equipment, as a form of smart home cleaning technology, has been widely used in daily life. The roller is one of its core cleaning components, primarily used to clean dust and debris from hard-to-reach areas such as walls, corners, and under furniture. However, the roller structure used in existing cleaning equipment still suffers from limited cleaning effectiveness in practical applications, severely restricting overall cleaning performance and user experience. Specifically, this is manifested in the following aspects: When cleaning vertical surfaces such as walls and furniture edges, rollers cannot fully conform to the side structure, resulting in a significant decrease in cleaning ability. Especially for areas such as wall sides, due to the gap between the roller and the vertical surface, it is difficult to effectively remove dust adhering to the vertical surface, which can easily lead to the accumulation of debris. Utility Model Content

[0003] The main purpose of this invention is to provide a roller assembly and cleaning equipment to solve the problem that existing cleaning equipment rollers cannot effectively clean vertical surfaces.

[0004] To achieve the above objectives, the present invention proposes a roller assembly, which includes: a first roller component extending along a first direction; The second roller component extends along the first direction; and A connecting component includes a connector and a mating component, one of which is mounted on a first roller component and the other is mounted on a second roller component. The connector and the mating component cooperate with each other and are capable of relative movement in the first direction. The first roller component is configured to drive the connector and the mating component to move relative to each other by rotation, so as to adjust the distance between the first roller component and the second roller component.

[0005] In one embodiment, the relative movement of the connector and the mating member in the first direction has a first limit position and a second limit position; When the first roller component rotates along the first rotation direction, it drives the connecting member and the mating member to move to the first limit position. When the first roller component rotates along the second rotation direction, it drives the connecting member and the mating member to move to the second limit position.

[0006] In one embodiment, when the connector and the mating member are in the first limit position and the second limit position, the second roller component rotates along with the first roller component.

[0007] In one embodiment, one of the connector and the mating member is provided with a first guide portion extending along the first direction, and the other is provided with a mating portion that mates with the first guide portion. The mating part is movable along the extension direction of the first guide part, so that the connector and the mating part move relative to each other in the first direction.

[0008] In one embodiment, the mating member is hollow, and the first guide portion includes a spiral groove formed on the inner sidewall of the mating member and extending along the first direction. The mating part is disposed on the connector, at least a portion of the connector is located within the mating part and is movable relative to the mating part in the first direction, and at least a portion of the mating part is located within the spiral groove.

[0009] In one embodiment, the mating component is hollow, and the first guide portion is disposed on the inner sidewall of the mating component; The mating component is further provided with a second guide portion at its opening position. The second guide portion is located on one side of the first guide portion in the first direction and is connected to the first guide portion. The second guide part is used to guide the mating part to move from the first direction to mat with the first guide part.

[0010] In one embodiment, the first guide portion includes a spiral groove formed on the inner sidewall of the mating member and extending along the first direction; The second guide portion includes a guide hole disposed at the opening position of the mating member. The guide hole is located on one side of the spiral groove in the first direction and communicates with the spiral groove. The depth of the guide hole is less than the groove depth of the spiral groove. The portion of the connector with the mating part is deformable, so that the mating part moves from the guide hole to the spiral groove in the first direction.

[0011] In one embodiment, the connector is hollow to form a cavity, and the connector has a clearance space at its end in the first direction, the clearance space communicating with the cavity; The mating part is located at the end of the connector in the first direction.

[0012] In one embodiment, the first roller component includes: cylindrical body; and A driving component is disposed inside the cylinder, and the output end of the driving component is connected to the cylinder. At least a portion of the connector is disposed within the cylinder and connected to the output end of the drive component.

[0013] In one embodiment, the roller assembly further includes: A limiting member is provided around the connector and is clearance-fitted with the connector; The cylinder rotates relative to the limiting member.

[0014] In one embodiment, at least a portion of the limiting member is located inside the cylinder; The roller assembly further includes a rotating support member disposed between the inner wall of the cylinder and the outer wall of the limiting member.

[0015] This utility model also proposes a cleaning device including: case; Wheel assembly, disposed on the housing; A dust collection box is disposed inside the housing; A cleaning component, disposed in the housing, includes a roller assembly and at least one cleaning part; A suction assembly, disposed within the housing, is used to generate a suction airflow to draw debris from the cleaning component into the dust collection box; At least one of the cleaning parts is disposed at the end of the second roller component.

[0016] In the technical solution of this application, the rotation of the first roller component drives the connecting member and the mating member to move relative to each other in the first direction, thereby adjusting the distance between the first roller component and the second roller component in the first direction. This allows the roller assembly to adapt to various working environments. For example, when cleaning a flat surface, the first roller component can rotate to drive the second roller component closer together to work together to clean the surface. When cleaning a vertical surface, the first roller component can rotate to drive the second roller component away from the first roller component, thus increasing the overall size of the roller assembly in the first direction. In this case, during cleaning, the end of the second roller component can contact the vertical surface and clean it, such as cleaning baseboards or the edges of walls. In summary, the roller assembly in this embodiment can effectively clean vertical surfaces. Attached Figure Description

[0024] Cleaning equipment, as a form of smart home cleaning technology, has been widely used in daily life. The roller is one of its core cleaning components, primarily used to clean dust and debris from hard-to-reach areas such as walls, corners, and under furniture. However, the roller structure used in existing cleaning equipment still suffers from limited cleaning effectiveness in practical applications, severely restricting overall cleaning performance and user experience. Specifically, this is manifested in the following aspects: When cleaning vertical surfaces such as walls and furniture edges, rollers cannot fully conform to the side structure, resulting in a significant decrease in cleaning ability. Especially for areas such as wall sides, due to the gap between the roller and the vertical surface, it is difficult to effectively remove dust adhering to the vertical surface, which can easily lead to the accumulation of debris.

[0025] In view of this, this application proposes a roller assembly, Figures 1 to 4 These are some embodiments of this application.

[0026] Please see Figures 1 to 3 In some embodiments of this application, the roller assembly 100 includes a first roller component 1 and a second roller component 2, the first roller component 1 extending along a first direction and the second roller component 2 also extending along the first direction; wherein the first roller component 1 and the second roller component 2 can cooperate with each other to clean flat areas such as the ground, wall edges, wall corners and the bottom of furniture.

[0027] In the roller assembly 100, the relative positions of the first roller component 1 and the second roller component 2 are not limited; they can be arranged crosswise or parallel to each other, etc.

[0028] In one specific embodiment of this application, the rotation axes of the first roller component 1 and the second roller component 2 are on the same straight line, that is, the first roller component 1 and the second roller component 2 are parallel to each other.

[0029] In some embodiments of this application, the roller assembly 100 further includes a connecting component 3, which includes a connector 31 and a mating component 32. One of the connector 31 and the mating component 32 is disposed in the first roller assembly 1, and the other is disposed in the second roller assembly 2. The connector 31 and the mating component 32 cooperate with each other and are capable of relative movement in the first direction; that is, the relative movement of the connector 31 and the mating component 32 in the first direction can adjust the distance between the first roller assembly 1 and the second roller assembly 2 in the first direction. In one embodiment, the connector 31 is disposed on the first roller component 1, and the mating component 32 is disposed on the second roller component 2.

[0030] In another embodiment, the mating member 32 is disposed on the first roller component 1, and the connecting member 31 is disposed on the second roller component.

[0031] The first roller component 1 is configured to drive the connector 31 and the mating component 32 to move relative to each other by rotation, so as to adjust the distance between the first roller component 1 and the second roller component 2; that is, the rotation of the first roller component 1 can cause the connector 31 and the mating component 32 to move relative to each other in a first direction, thereby adjusting the distance between the first roller component 1 and the second roller component 2 in the first direction.

[0032] Of course, the rotation of the first roller component 1 itself also puts the first roller component 1 into cleaning mode and cleans the area to be cleaned. That is, while the first roller component 1 is rotating to clean, it can also rotate to adjust the distance between the first roller component 1 and the second roller component 2 in the first direction.

[0033] In one embodiment, the connector 31 and the mating member 32 form a bolt-nut-like mating relationship, causing the connector 31 and the mating member 32 to move relative to each other in a first direction when the first roller member 1 rotates.

[0034] In another embodiment, the connector 31 and the mating member 32 form a mating relationship similar to a spiral groove and a locking protrusion, so that when the first roller member 1 rotates, the connector 31 and the mating member 32 move relative to each other in a first direction.

[0035] It is understandable that the distance adjustment between the first roller component 1 and the second roller component 2 in the first direction is not affected by the positional arrangement of the first roller component 1 and the second roller component 2, as long as the connecting piece 31 and the mating piece 32 are connected to the first roller component 1 and the second roller component 2.

[0036] In the technical solution of this application, the rotation of the first roller component 1 drives the connecting member 31 and the mating member 32 to move relative to each other in the first direction, thereby adjusting the distance between the first roller component 1 and the second roller component 2 in the first direction. This allows the roller assembly 100 to adapt to various working environments. For example, when cleaning a flat surface, the first roller component 1 can rotate to drive the second roller component 2 closer together to work together to clean the surface. When cleaning a vertical surface, the first roller component 1 can rotate to drive the second roller component 2 away from the first roller component 1, thereby increasing the overall size of the roller assembly 100 in the first direction. In this case, during cleaning, the end of the second roller component 2 can contact the vertical surface and clean it, such as cleaning baseboards or the edges of walls. In summary, the roller assembly 100 in this embodiment can effectively clean vertical surfaces.

[0037] When the roller assembly 100 is applied to a cleaning device, the second roller component 2 can extend out of the housing of the cleaning device to clean the vertical surface, thereby improving the functionality and practicality of the cleaning device.

[0038] It is understood that the cleaning device of the cleaning equipment in the related technology usually does not extend beyond the range of the equipment housing, and the width of the housing is greater than the length of the cleaning device. This structure makes it impossible for the equipment to effectively clean the edge areas near the vertical surfaces such as walls and furniture. In the embodiment of this application, the second roller component 2 can extend beyond the housing of the cleaning equipment, so that the second roller component 2 can reach and clean the aforementioned edge areas, that is, the second roller component 2 can effectively clean the edge areas of the ground near the vertical surfaces.

[0039] In addition, to achieve cleaning of the vertical facade itself, a dedicated cleaning part, such as a cleaning brush, can be provided at the end of the second roller component 2. This cleaning part can be integrally formed with the second roller component 2 or installed as a separate component at the end of the second roller component 2, thereby achieving direct and effective cleaning of the vertical facade. It should be noted that when the first roller component 1 and the second roller component 2 are close to each other, there can be a gap or complete contact between the first roller component 1 and the second roller component 2, which is not limited here.

[0040] When the first roller component 1 and the second roller component 2 are far apart from each other, the distance between the first roller component 1 and the second roller component 2 is not limited and can be adapted according to the model of the cleaning equipment.

[0041] In some embodiments of this application, the relative movement of the connector 31 and the mating member 32 in the first direction has a first limit position and a second limit position; the relative position change between the connector 31 and the mating member 32 can only be carried out between the first limit position and the second limit position, thereby effectively preventing the connector 31 and the mating member 32 from separating from each other during operation.

[0042] When the first roller component 1 rotates along the first rotation direction, it drives the connecting member 31 and the mating member 32 to move to the first limit position. When the first roller component 1 rotates along the second rotation direction, it drives the connecting member 31 and the mating member 32 to move to the second limit position. That is, when the first roller component 1 and the second roller component 2 rotate in two different directions, they can drive the connecting member 31 and the mating member 32 to perform relative movements in different directions, thereby causing the second roller component 2 to move closer to or further away from the first roller component 1, so that the second roller component 2 can cooperate with the first roller component 1 to clean the plane or extend out of the housing of the cleaning device to clean the vertical surface.

[0043] For example, when the first roller component 1 rotates clockwise around the axis extending in the first direction, the second roller component 2 is driven to approach through the connecting component 3, and the first roller component 1 and the second roller component 2 cooperate to clean the plane.

[0044] When the first roller component 1 reverses its direction around the axis extending in the first direction, the second roller component 2 is driven away by the connecting component 3. The first roller component 1 cleans the plane, and the second roller component 2 cleans the vertical surface.

[0045] When the roller assembly 100 is applied to a cleaning device, the cleaning device can intelligently control the rotation direction of the first roller component 1 to adjust the cleaning mode of the cleaning device.

[0046] In some embodiments of this application, when the connector 31 and the mating member 32 are in the first limit position and the second limit position, the second roller component 2 rotates with the first roller component 1; this arrangement eliminates the need for a separate drive unit for the second roller component 2, making the overall components of the roller assembly 100 compact and reducing costs.

[0047] Meanwhile, when the connector 31 and the mating part 32 are in the first limit position and the second limit position, the roller assembly 100 can be in different working modes to clean the plane or vertical surface.

[0048] When the connector 31 and the mating part 32 are in the first limit position, the second roller component 2 approaches the first roller component 1, and the two work together to perform planar cleaning.

[0049] When the connector 31 and mating part 32 are in the second limit position, the second roller component 2 moves away from the first roller component 2 to increase the function of cleaning the vertical surface.

[0050] It should be noted that when the second roller component 2 is cleaning the vertical surface, the second roller component 2 still maintains the state of cleaning the flat surface.

[0051] Furthermore, when the relative positions of the connector 31 and the mating member 32 are between the first limit position and the second limit position, the first roller member 1 may or may not be able to drive the second roller member 2 to rotate, which is not limited here.

[0052] In some embodiments of this application, one of the connector 31 and the mating member 32 is provided with a first guide portion 4 extending along a first direction, and the other is provided with a mating portion 10 that mates with the first guide portion 4; the mating portion 10 is movable along the extending direction of the first guide portion 4, so that the connector 31 and the mating member 32 move relative to each other in the first direction; in this embodiment, the rotation of the first roller member 1 can drive the mating portion 10 to move on the first guide portion 4, so that the distance between the connector 31 and the mating member 32 changes, thereby realizing the adjustment of the relative position between the connector 31 and the mating member 32.

[0053] The cooperation between the first guide part 4 and the mating part 10 can limit the movement direction of the connector 31 and the mating part 32, so as to ensure that the relative movement path of the connector 31 and the mating part 32 is unique.

[0054] Specifically, in one embodiment of this application, the mating part 10 is disposed on the connector 31, and the first guide part 4 is disposed on the mating part 32.

[0055] Based on the aforementioned positions of the mating part 10 and the first guide part 4, the connecting member 31 moves together with the first roller component 1. In order to achieve the mating movement between the mating part 10 and the first guide part 4, thereby adjusting the distance between the first roller component 1 and the second roller component 2 in the first direction, in some embodiments of this application, at least a portion of the first guide part 4 is arranged in a spiral shape. When the connecting member 31 rotates with the first roller component 1, the mating part 10 located on the connecting member 31 can move along the spirally arranged first guide part 4, thereby driving the connecting member 31 and the mating member 32 to undergo relative displacement in the first direction, ultimately realizing the adjustment of the distance between the first roller component 1 and the second roller component 2.

[0056] The arrangement of the first guide part 4 is not limited. It can be a groove-like structure, such as a spiral groove, or a spirally arranged ridge structure. When the mating part 10 moves along the first guide part 4, the two can restrict the separation of the mating part 10 and the first guide part 4 through the concave-convex fit of their own structures.

[0057] In some embodiments of this application, the mating member 32 is hollow and has a spiral groove extending along the first direction on its inner sidewall, the spiral groove forming a first guide portion 4; the mating portion 10 is disposed on the connector, at least a portion of the connector 31 is located inside the mating member 32 and can move relative to the mating member 32 in the first direction, and at least a portion of the mating portion 10 is located inside the spiral groove; wherein, the rotation of the first roller component 1 can drive the connector 31 or the mating member 32 to rotate, and due to the spiral groove on the mating member 32, when the connector 31 and the mating member 32 rotate relative to each other, the distance between the connector 31 and the mating member 32 will also change, thereby realizing the adjustment of the relative position between the connector 31 and the mating member 32.

[0058] It should be further explained that when the mating part 10 is located at both ends of the spiral groove, that is, when the connecting part 31 and the mating part 32 are in the first limit position or the second limit position, the rotation of the first roller component 1 will not cause relative movement between the connecting part 31 and the mating part 32. With the cooperation of the groove wall of the spiral groove and the mating part 10, the connecting part 31 and the mating part 32 are relatively fixed, so that the first roller component 1 can drive the second roller component 2 to move synchronously.

[0059] Of course, the engagement between the spiral groove and the mating part 10 can also prevent the connector 31 and the mating part 32 from separating from each other.

[0060] Furthermore, the portion of the connector 31 located within the mating member 32 is clearance-fitted with the mating member 32 to prevent relative movement between the connector 31 and the mating member 32, which could cause the mating portion 10 to disengage from the spiral groove.

[0061] The number of spiral grooves and mating parts 10 is not limited; there can be one or more.

[0062] The number of mating parts 10 provided in a spiral groove is not limited; there can be one or more.

[0063] In one specific embodiment of this application, the number of spiral grooves is set to two, and they are arranged opposite each other in the radial direction of the mating member 32. The number of mating parts 10 is also set to two, and they are arranged opposite each other in the radial direction of the connecting member 31 and embedded in the corresponding spiral groove, so as to enhance the stability of the mutual rotation of the connecting member 31 and the mating member 32.

[0064] It should be further noted that the spiral groove in the embodiments of this application may or may not penetrate the mating member 32 in the axial direction; no limitation is made here.

[0065] In some embodiments of this application, the mating part 32 is hollow, the first guide part 4 is disposed on the inner sidewall of the mating part 32, and the mating part 32 is also provided with a second guide part 5 at its opening position. The second guide part 5 is located on one side of the first guide part 4 in the first direction and is connected to the first guide part 4. The second guide part 5 is used to guide the mating part 10 to move from the first direction to engage with the first guide part 4. This arrangement facilitates the assembly of the connecting part 31 and the mating part 32 by the operator or operating tool, so that when the connecting part 31 and the mating part 32 are assembled, the mating part 10 can smoothly engage with the first guide part 4.

[0066] Based on this embodiment, in order for the connector 31 and the mating part 32 to fit together properly, at least a portion of the connector 31 is located inside the mating part 32 when assembled with the mating part 32.

[0067] In some embodiments of this application, the first guide part 4 can also be disposed on the outer side wall of the mating part 32, and the second guide part 5 is also disposed on the outer side wall of the mating part 32 and connected to the first guide part 4. The second guide part 5 is disposed so that the operator or operating tool can assemble the connector 31 and the mating part 32, so that when the connector 31 and the mating part 32 are assembled, the mating part 10 can smoothly engage with the first guide part 4.

[0068] Based on this embodiment, in order for the connector 31 and the mating part 32 to fit together properly, at least a portion of the mating part 32 is located inside the connector 31 when assembled with the connector 31.

[0069] In some embodiments of this application, the first guide portion 4 includes a spiral groove formed on the inner sidewall of the mating member 32 and extending along a first direction; the second guide portion 5 includes a guide hole disposed at the opening position of the mating member 32, the guide hole being located on one side of the spiral groove in the first direction and connected to the spiral groove, the depth of the guide hole being less than the groove depth of the spiral groove; the portion of the connecting member 31 provided with the mating portion 10 is deformable, so that the mating portion 10 moves from the guide hole to the spiral groove in the first direction; this arrangement is such that when the connecting member 31 and the mating member 32 are assembled, the mating portion 10 can be smoothly inserted into the spiral groove.

[0070] The above embodiments will be described in detail. When the connector 31 and the mating part 32 are assembled, when the mating part 10 of the connector 31 is inserted into the guide hole, the position of the connector 31 where the mating part 10 is provided is deformed, so that the mating part 10 can move smoothly along the guide hole. When the mating part 10 moves into the spiral groove, the position of the connector 31 where the mating part 10 is provided returns to its original state. At this time, the mating part 10 is stuck by the groove wall at the connection between the guide hole and the spiral groove, so that the mating part 10 cannot be dislodged from the spiral groove.

[0071] In some embodiments of this application, in the first direction, the distance between the two opposite groove walls of the guide hole gradually tilts toward the spiral groove, which not only facilitates the mating part 10 to enter the guide hole, but also effectively prevents the mating part 10 from coming out of the spiral groove.

[0072] Please see Figure 2 and Figure 4 In some embodiments of this application, the connector 31 is hollow to form a cavity 6, and the end 31A of the connector in the first direction is provided with a clearance space 7, which communicates with the cavity 6. By providing the clearance space 7, the end 31A of the connector 31 has elastic deformation capability. When the mating part 10 enters the guide hole, the clearance space 7 and the cavity 6 provide clearance space for the end 31A of the connector 31 to contract. When the mating part 10 enters the spiral groove, the end 31A of the connector 31 returns to its original shape to prevent the mating part 10 from coming out of the spiral groove.

[0073] In some embodiments of this application, the clearance space includes a clearance notch provided at the end 31A of the connector 31. The clearance notch can cooperate with the cavity 6 to provide space for the deformation of the end 31A of the connector 31. For example, when the mating part 10 enters the guide hole, the clearance notch and the cavity 6 provide clearance space for the end 31A of the connector 31 to contract. When the mating part 10 enters the spiral groove, the end 31A of the connector 31 returns to its original shape to prevent the mating part 10 from coming out of the spiral groove.

[0074] Please see Figure 4 In some embodiments of this application, multiple clearance spaces 7 are provided, and the multiple clearance spaces 7 are arranged around the periphery of the connector 31. This arrangement allows the multiple clamping spaces 7 to divide the end 31A of the connector 31 into multiple sheet-like structures with gaps between them. When the mating part 10 enters the guide hole, the gap between two adjacent sheet-like structures shrinks, and the outer peripheral dimension of the end 31A of the connector 31 decreases, that is, the end 31A of the connector 31 deforms. When the mating part 10 enters the spiral groove, the two adjacent sheet-like structures reset, that is, the end 31A of the connector 31 resets, so as to prevent the mating part 10 from coming out of the spiral groove.

[0075] In addition, since the mating part 10 is embedded in the spiral groove and is not easy to come out, in order to facilitate the user or maintenance personnel to disassemble the connector 31 and the mating part 32, the spiral groove provided in the mating part 32 is provided through the mating part 4, so that the user or maintenance personnel can push against the mating part 10 at the spiral groove, so that the mating part 10 separates from the spiral groove, thereby realizing the disassembly of the connector 31 and the mating part 32.

[0076] Please refer to it again. Figure 2In some embodiments of this application, the first roller component 1 includes a cylinder 11 and a driving member 12. The driving member 12 is disposed inside the cylinder 11, and the output end of the driving member 12 is connected to the cylinder 11. At least a portion of the connecting member 31 is disposed inside the cylinder 11 and connected to the output end of the driving member 12. In this embodiment, through the connection of the output end of the driving member 12, the driving member 12 drives the connecting member 31 and the mating member 32 to rotate relative to each other while driving the cylinder 11 to rotate. This allows the first roller component 1 to drive the connecting member 31 and the mating member 32 to move relative to each other through rotation, thereby realizing the function of adjusting the distance between the first roller component 1 and the second roller component 2.

[0077] In some embodiments of this application, the drive element 12 includes a drive motor.

[0078] In some embodiments of this application, the roller assembly 100 further includes a limiting member 8, which is disposed around the connector 31 and is clearance-fitted with the connector 31; wherein the cylinder 11 rotates relative to the limiting member 8; in this embodiment, by providing the limiting member 8, the movement of the connector 31 in other directions is restricted, thereby improving the stability of the rotation of the connector 31.

[0079] The cylinder 11 rotates relative to the limiting member 8 to avoid the limiting member 8 interfering with the rotation of the cylinder 11.

[0080] In some embodiments of this application, at least a portion of the limiting member 8 is located inside the cylinder 11; the roller assembly 100 further includes a rotating support member 9, which is disposed between the inner wall of the cylinder 11 and the outer wall of the limiting member 8; this arrangement is because the cylinder 11 is a circumferential component, and the arrangement of the rotating support member 9 between the outer wall of the limiting member 8 and the inner wall of the cylinder 11 ensures that the limiting member 8 is securely fixed inside the cylinder 11 while also preventing the limiting member 8 from interfering with the rotation of the cylinder 11.

[0081] In some embodiments of this application, the rotating support 9 includes a bearing, the inner ring of which is fixed to the outer wall of the limiting member 8, and the outer ring of which is fixed to the inner wall of the cylinder 11.

[0082] The number of bearings is not limited; there may be one or more. In some embodiments of this application, two bearings are provided between the limiting member 8 and the cylinder 11, and the two bearings are arranged in the first direction.

[0083] It should be further noted that the limiting member 8 should also prevent the rotating support member 9 from moving in the first direction. That is, the limiting member 8 is provided with a locking protrusion or a locking groove to restrict the movement of the rotating support member 9 in the first direction.

[0084] In some embodiments of this application, the size of the first roller component 1 in the first direction is larger than the size of the second roller component 2 in the first direction; this is because the first roller component 1 plays the main role of planar cleaning; while the positional movement of the second roller component 2 allows the second roller component 2 to perform planar cleaning as well as vertical cleaning.

[0085] This application also proposes a cleaning device, which includes a housing, a wheel assembly, a dust collection box, a cleaning component, and a suction assembly. The wheel assembly is disposed in the housing; the dust collection box is disposed inside the housing; the cleaning component is disposed in the housing and includes a roller assembly and at least one cleaning part; the suction assembly is disposed inside the housing and is used to generate a suction airflow to suck the debris on the cleaning component into the dust collection box, and at least one of the cleaning parts is disposed at the end of the second roller assembly.

[0086] The cleaning device in this embodiment expands its cleaning range by integrating the cleaning unit into the end of the second roller component 2, enabling it to effectively reach vertical surfaces and the edge areas where the ground meets the vertical surfaces. This achieves a thorough cleaning effect, extending the device's functionality from two-dimensional ground to three-dimensional space and significantly improving its overall cleaning capabilities. Furthermore, through the efficient collaboration between the suction component and the cleaning component, this design can quickly suck up or stir up the debris from the cleaning component into the dust collection box, effectively preventing debris splashing and secondary pollution. Thus, without significantly increasing the overall complexity, the device achieves a simultaneous improvement in cleaning efficiency and functional integration.

[0087] In some embodiments of this application, multiple cleaning units are provided, and the multiple cleaning units are also respectively provided on the periphery of the first roller component 1 and the second roller component 2, so that the first roller component 1 and the second roller component 2 can clean the ground area.

[0088] In addition, the wheel setup allows the cleaning equipment to operate on the ground.

[0089] The type of cleaning equipment in this application embodiment is not limited, and can be a sweeping robot, floor scrubber, etc.
