Description

Technical Field

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

[0002] Cleaning devices such as mite removers, vacuum cleaners, and robotic vacuum cleaners are commonly used in households. Vacuum cleaners and robotic vacuum cleaners can clean floors, while mite removers can remove dust and worms from surfaces such as mattresses and leather.

[0003] In related technologies, cleaning equipment typically includes a housing and a fan unit installed inside the housing. The airflow generated by the fan unit creates suction at the air inlet of the housing. A roller brush can be installed at the position corresponding to the air inlet. The roller brush rolls on the surface to be cleaned, picking up dust and hair, and the suction from the air inlet draws the dust and hair into the equipment, thus achieving the cleaning function.

[0004] However, under the suction of the air inlet, hair fibers easily get tangled on the roller brush as it rotates, making them difficult to clean. Utility Model Content

[0005] This application provides a roller brush and cleaning device to solve the technical problem that when cleaning the surface to be cleaned, hair fibers are easily entangled on the roller brush as it rotates under the suction of the air inlet, making them difficult to clean.

[0006] In a first aspect, this application provides a roller brush for cleaning equipment, wherein the roller brush is rotatably disposed on the cleaning equipment; the roller brush includes a roller and a plurality of flexible cleaning elements; the plurality of flexible cleaning elements are circumferentially spaced around the roller.

[0007] Each flexible cleaning element has at least one cleaning portion that protrudes from the surface of the roller; in the direction surrounding the circumference of the roller, the cleaning portions of at least one flexible cleaning element are staggered with the cleaning portions of at least some other flexible cleaning elements; the staggered cleaning portions have overlapping areas in the circumference of the roller.

[0008] The flexible cleaning component of the roller brush provided in this application has one or more cleaning sections. The gaps between the cleaning sections or between the cleaning sections and the end of the roller can change the airflow direction of the roller, which can reduce hair fiber entanglement. The staggered arrangement of the cleaning sections of the circumferential flexible cleaning component has overlapping areas in the circumferential direction, so that there are no cleaning missed areas along the axial direction when the roller brush is cleaning, thus improving cleaning efficiency.

[0009] As an alternative implementation, multiple flexible cleaning components are detachably connected to the roller.

[0010] With this design, the flexible cleaning component is detachable, making it easy to remove and clean when a small amount of hair is tangled.

[0011] As an optional implementation, the circumference of the roller has a plurality of spaced insertion slots; the insertion slots extend from one end to the other along the axial direction of the roller; a plurality of flexible cleaning components are respectively inserted into the plurality of insertion slots.

[0012] This configuration secures the flexible cleaning component, preventing it from shifting radially along the roller.

[0013] As an alternative implementation, the flexible cleaning component includes a connector that is inserted into the connector groove from the end of the connector groove. The cleaning component is connected to the connector and protrudes out of the connector groove in a direction away from the roller surface.

[0014] This design allows for the simultaneous installation of multiple cleaning units via the connector, improving installation and disassembly efficiency.

[0015] As an alternative implementation, at least one flexible cleaning element has at least two cleaning sections, which are spaced apart along the extension direction of the flexible cleaning element and form a vacant area; in other flexible cleaning elements, the cleaning section of at least one of them is opposite to the vacant area in the circumferential direction of the roller brush rotation.

[0016] This design, through the cooperation of multiple flexible cleaning components, can fully cover the cleaning area, prevent omissions, and improve cleaning efficiency.

[0017] As an optional implementation, the plurality of flexible cleaning components include a first cleaning component and a second cleaning component; the first cleaning component has a single cleaning part; the second cleaning component has two cleaning parts spaced apart and forming an empty area; in the circumferential direction of the rotation of the roller brush, the cleaning part of the first cleaning component is opposite to the empty area.

[0018] With this configuration, the cleaning section of the first cleaning component can clean the areas missed by the second cleaning component, thus improving cleaning efficiency.

[0019] As an optional implementation, there are multiple first cleaning elements and multiple second cleaning elements, which are arranged alternately in the rotation circumference of the roller brush.

[0020] With this setup, the first and second cleaning components work together to fully cover the cleaning area, preventing omissions and improving cleaning efficiency.

[0021] As an optional implementation, the length of the cleaning section of the first cleaning component is greater than or equal to the length of the vacant area.

[0022] This setup avoids missing any areas during cleaning and improves cleaning effectiveness.

[0023] As an alternative implementation, the roller includes a roller body and a plurality of support portions; the plurality of support portions are disposed on the periphery of the roller body and protrude from the surface of the roller body; the insertion groove is located on the side of the support portion away from the roller body.

[0024] This design improves the support stability of the insertion slot, thereby enhancing the installation stability of the flexible cleaning component.

[0025] As an optional implementation, the roller has two connecting ends at both ends in the axial direction. The connecting ends are coaxial with the roller and have a diameter greater than or equal to the diameter of the roller. The two ends of the support are connected to the two connecting ends respectively. The side of the support near the roller has a gap with the surface of the roller to form a ventilation gap between the support and the roller.

[0026] This configuration, through the fixing of the two connecting ends, can further enhance the support stability of the support part; and the ventilation gap formed between the support part and the roller can increase the ventilation area and improve the airflow efficiency.

[0027] As an optional implementation, the support has at least one through hole that penetrates the support and the through hole has an angle with the axial direction of the roller.

[0028] This design allows for increased ventilation area through the through holes, improving airflow and reducing hair entanglement in the roller brush.

[0029] As an optional implementation, the roller brush also includes two end caps, which are respectively connected to both ends of the roller axis; the two ends of the flexible cleaning element abut against the two end caps respectively.

[0030] This design provides additional support to the rollers through the end caps, enhancing the structural stability of the roller brush.

[0031] Secondly, this application provides a cleaning device, which includes a device body and the aforementioned roller brush, with the roller brush rotatably mounted on the device body.

[0032] The cleaning equipment provided in this application uses the aforementioned roller brush to clean the surface to be cleaned, which can avoid hair tangling and improve cleaning efficiency.

[0033] This application provides a roller brush and a cleaning device. The roller brush is used in the cleaning device and is rotatably mounted on the cleaning device. The roller brush includes a roller and a plurality of flexible cleaning elements. The plurality of flexible cleaning elements are circumferentially spaced around the roller. Each flexible cleaning element has at least one cleaning portion that protrudes from the surface of the roller. In the direction circumferentially around the roller, the cleaning portion of at least one flexible cleaning element is staggered with the cleaning portions of at least some other flexible cleaning elements. The staggered cleaning portions have an overlapping area in the circumferential direction of the roller. When the roller brush rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning device can flow through the spaces between the staggered cleaning portions, improving the overall airflow path of the cleaning device and reducing hair entanglement. Simultaneously, the flexible cleaning elements are detachable, facilitating the removal of small amounts of entangled hair.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0051] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] Cleaning devices such as mite removers, vacuum cleaners, and robotic vacuum cleaners are commonly used in households. Vacuum cleaners and robotic vacuum cleaners can clean floors, while mite removers can remove dust and worms from surfaces such as mattresses and leather. Cleaning devices typically consist of a casing and a fan unit housed within it. The airflow generated by the fan unit creates suction at the air inlet on the casing. A roller brush can be positioned at the air inlet; this brush rolls across the surface being cleaned, picking up dust and hair, which are then drawn into the device by the suction, thus achieving the cleaning function.

[0054] However, under the suction of the air inlet, hair fibers easily get tangled on the roller brush as it rotates, and the tangling becomes tighter and tighter, making it difficult for the roller brush to clean.

[0055] To address the aforementioned technical problems, this application provides a roller brush and a cleaning device. The roller brush, through its flexible cleaning component structure design, arranges the cleaning parts of the flexible cleaning components in an alternating pattern along the circumference of the roller. This allows the empty areas of the flexible cleaning components and the gaps between adjacent flexible cleaning components to form airflow channels during cleaning, changing the direction of suction generated by the air inlet on the cleaning device. This improves the overall airflow layout of the cleaning device, preventing hair fibers from tangling on the roller brush. Adhered hair fibers are more easily drawn into the cleaning device, resulting in better cleaning performance. Furthermore, the flexible cleaning components are detachable, facilitating removal and cleaning when a small amount of hair fibers are tangled.

[0056] The following is an example illustrating the application scenarios of the roller brush and cleaning equipment provided in the embodiments of this application.

[0057] The roller brush provided in this application embodiment is used in cleaning equipment. The cleaning equipment is a cleaning tool with a roller brush structure. Specifically, the product type of the cleaning equipment in this application embodiment may include, but is not limited to, mite removers, vacuum cleaners, sweeping machines, and robotic vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used on soft surfaces such as carpets, sheets, sofas, and clothing, or on smooth surfaces such as floor tiles. This application embodiment does not make any specific limitations in this regard.

[0058] Figure 1This is a schematic diagram of a roller brush provided in an embodiment of this application applied to a cleaning device; Figure 2 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of the roller brush provided in an embodiment of this application; Figure 4 An exploded view of the roller brush provided in the embodiments of this application; Figure 5 A schematic diagram of the first cleaning component provided in an embodiment of this application; Figure 6 A schematic diagram of the second cleaning component provided in an embodiment of this application; Figure 7 A side sectional view of the roller brush provided in an embodiment of this application; Figure 8 This is a schematic diagram of a through hole provided in an embodiment of this application.

[0059] See Figures 1 to 8 As shown, this application embodiment provides a roller brush 100 for cleaning device 10, and the roller brush 100 is rotatably disposed on the cleaning device 10. When the cleaning device 10 cleans the surface to be cleaned, the roller brush 100 can contact the surface to be cleaned, and as the cleaning device 10 moves, the roller brush 100 can roll and rub the surface to be cleaned to clean the dust and fibers attached to the surface to be cleaned.

[0060] It should be noted that the cleaning device 10 has a roller brush 100 chamber, in which the roller brush 100 is rotatably disposed; the cleaning device 10 has an air inlet facing the roller brush 100 chamber, which provides negative pressure suction to draw the surface to be cleaned and dust, hair, etc., rolled up by the roller brush 100 into the cleaning device 10. The roller brush 100 and the air inlet work together to achieve the cleaning effect.

[0061] The roller brush 100 provided in this application embodiment includes a roller 110 and a plurality of flexible cleaning components 120. The plurality of flexible cleaning components 120 are arranged circumferentially around the roller 110 and are all detachably connected to the roller 110.

[0062] Understandably, the roller 110 can be rotatably connected to the cleaning device 10. The roller 110 supports the flexible cleaning element 120. The cleaning part 121 of the flexible cleaning element 120 is elastic and can be a rubber strip. When the cleaning part 121 of the flexible cleaning element 120 contacts the surface to be cleaned, it can be squeezed to produce elastic deformation, thereby increasing the friction between it and the surface to be cleaned. During cleaning, the rotation of the roller 110 drives multiple flexible cleaning elements 120 to rub and pat the surface to be cleaned in sequence, picking up the attached dust and hair. At the same time, the cleaning device 10 can be equipped with a fan to generate negative pressure airflow. The negative pressure airflow is used in conjunction with the roller brush 100 to use negative pressure suction to suck the dust and hair fibers on the surface to be cleaned and the flexible cleaning elements 120 into the cleaning device 10. Alternatively, the roller 110 can be independent of the flexible cleaning element 120 and can function as a roller brush 100 to clean dust or hair.

[0063] As one possible implementation, each flexible cleaning element 120 has at least one cleaning portion 121 that protrudes from the surface of the roller 110; in the direction surrounding the circumference of the roller 110, the cleaning portions 121 of at least one flexible cleaning element 120 are staggered with the cleaning portions 121 of at least some other flexible cleaning elements 120; the staggered cleaning portions 121 have overlapping areas in the circumference of the roller 110.

[0064] It is understood that the cleaning section 121 is used to contact and clean the surface to be cleaned. There are gaps between the cleaning sections 121 and between the cleaning section 121 and the main body 200 of the equipment. These gaps and the gaps between two adjacent flexible cleaning parts 120 can form airflow channels, which can improve the layout of the overall airflow path of the cleaning equipment 10, thereby preventing hair fibers from getting tangled on the roller brush 100, making it easier for attached hair fibers to be sucked into the cleaning equipment 10. The flexible cleaning parts 120 are detachable, making it easy to remove and clean when a small amount of hair fibers are tangled. In the circumferential direction of the roller, the cleaning sections 121 of one or more flexible cleaning parts 120 are staggered with the cleaning sections 121 of one or more other flexible cleaning parts 120. When the roller 110 rotates, these staggered cleaning sections 121 have overlapping parts in the area they rotate through in the circumferential direction, so that multiple staggered cleaning sections can cover the entire area in the axial direction of the roller 110 during cleaning, avoiding any areas that are missed during cleaning.

[0065] It should be noted that the negative pressure airflow generated on the cleaning device 10 can flow through the periphery of the roller brush 100 on the one hand, and through the airflow channel between the flexible cleaning parts 121 on the other hand. This allows the periphery of the roller 110 and the flexible cleaning parts 120 themselves to form airflow paths, improving air volume and airflow efficiency. This enables the cleaning device 10 to have a good cleaning effect on hair fibers that are difficult to clean on soft surfaces, and can prevent hair fibers from remaining on the surface to be cleaned.

[0066] The cleaning surface of the cleaning section 121 can be provided with serrated grooves, with the spacing between the serrations being greater than or equal to 1% of the overall length of the roller brush 100 and less than or equal to 90% of the overall length of the roller brush 100. The serrated groove structure can increase the contact area between the cleaning section 121 and the surface to be cleaned. Especially for uneven and soft surfaces to be cleaned, the serrated grooves can more effectively scrape off and absorb dust, hair fibers and other debris.

[0067] For example, the saw teeth can be triangular saw teeth, trapezoidal saw teeth, circular arc saw teeth, etc., and this application embodiment does not make specific limitations; the ratio of the saw tooth spacing to the overall length of the roller brush 100 can be 1%, 5%, 10%, 50%, 90%, etc., and this application embodiment does not make specific limitations.

[0068] As one possible implementation, the circumference of the roller 110 has a plurality of spaced insertion slots 111, which extend from one end to the other along the axial direction of the roller 110, and a plurality of flexible cleaning components 120 are respectively inserted into the plurality of insertion slots 111.

[0069] Understandably, the insertion slot 111 extends from one end of the roller 110 to the other, and the flexible cleaning component 120 can be inserted or removed from the side for easy and quick replacement; the circumferential spacing of the multiple insertion slots 111 can be set according to the rotational speed of the roller 110.

[0070] Optionally, the number of roller brush grooves 111 can be 2, 3, 4, 5, etc., and this embodiment does not make a specific limitation.

[0071] As one possible implementation, the flexible cleaning component 120 includes a plug portion 122, which is inserted into the plug groove 111 from the end of the plug groove 111. The cleaning part 121 is connected to the plug portion 122 and protrudes out of the plug groove 111 in a direction away from the surface of the roller 110.

[0072] It is understood that the insertion groove 111 has an opening extending along the axial direction of the roller 110 on the side opposite to the surface of the roller 110. The width of the opening can be equal to or slightly larger than the width of the cleaning part 121, so that when the insertion part 122 is inserted into the insertion groove 111, the cleaning part 121 can protrude to the outside of the insertion part 122. The insertion groove 111 can be a "T" shaped groove, a dovetail groove, etc., and this embodiment does not make specific limitations.

[0073] See Figures 3 to 6 As shown, as one possible implementation, at least one flexible cleaning member 120 has at least two cleaning portions 121, which are spaced apart along the extension direction of the flexible cleaning member 120 and form a vacancy area 123; in other flexible cleaning members 120, at least one of the cleaning portions 121 is opposite to the vacancy area 123 in the circumferential direction of the rotation of the roller brush 100.

[0074] It should be noted that the flexible cleaning element 120 with two or more cleaning parts 121 has an empty area 123, which is formed by the interval between the cleaning parts 121. When the flexible cleaning element 120 comes into contact with the surface to be cleaned, the empty area 123 can connect the front and rear spaces of the flexible cleaning element 120. The negative pressure suction inside the cleaning device 10 can suck dust and hair on the front side of the flexible cleaning element 120 along the cleaning direction into the cleaning device 10 through the empty area 123. Each empty area 123 has at least one cleaning part 121 opposite to it along the rotation circumference of the roller brush 100 to ensure that there are no cleaning omissions.

[0075] As one possible implementation, the multiple flexible cleaning elements 120 include a first cleaning element 124 and a second cleaning element 125; the first cleaning element 124 has a single cleaning portion 121; the second cleaning element 125 has two spaced-apart cleaning portions 121 and forms an empty area 123; in the circumferential direction of rotation of the roller brush 100, the cleaning portion 121 of the first cleaning element 124 is opposite to the empty area 123.

[0076] It should be noted that the length of the cleaning section 121 of the first cleaning component 124 is less than the overall length of the roller brush 100. A void area 123 can also be formed between the cleaning section 121 and the inner wall of the device body 200. When one end of the cleaning section 121 of the first cleaning component 124 abuts against the inner wall of the device body 200, it forms one void area 123. When the cleaning section 121 of the first cleaning component 124 does not abut against the inner wall of the device body 200, it forms two void areas 123. These two void areas 123 are located on both sides of the cleaning section 121 of the first cleaning component 124. Regardless of the arrangement, in the circumferential direction of the roller brush 100's rotation, the cleaning section 121 of the first cleaning component 124 is opposite to the void area 123 of the second cleaning component 125, and the cleaning section 121 of the second cleaning component 125 can also be opposite to the void area 123 of the first cleaning component 124 to fill in any missed cleaning areas.

[0077] As one possible implementation, there are multiple first cleaning elements 124 and multiple second cleaning elements 125, and the multiple first cleaning elements 124 and multiple second cleaning elements 125 are arranged alternately in the rotation circumference of the roller brush 100.

[0078] For example, when the cleaning device 10 is cleaning, the adjacent first cleaning element 124 and second cleaning element 125 can simultaneously contact the surface to be cleaned. Along the cleaning direction, the first cleaning element 124 and the second cleaning element 125 alternate in front. The empty areas 123 of the first cleaning element 124 and the second cleaning element 125 are connected through the gap between them to form an airflow channel, so that negative pressure airflow can flow through and draw the hair in the front area into the cleaning device 10 from the airflow channel. This can improve the cleaning effect and prevent hair from circumferentially entangled around the roller brush 100.

[0079] As one possible implementation, the length of the cleaning section 121 of the first cleaning component 124 is greater than or equal to the length of the vacant area 123.

[0080] It is understandable that the length of the cleaning section 121 of the first cleaning component 124 must be greater than or equal to the length of the empty area 123 of the second cleaning component 125 in order to avoid any areas being missed during cleaning. At the same time, the cleaning section 121 of the second cleaning component 125 must also completely cover the empty area 123 of the first cleaning component 124 in the circumferential direction of the roller 110.

[0081] In one possible implementation, the roller 110 includes a roller body 112 and a plurality of support portions 113; the plurality of support portions 113 are disposed on the periphery of the roller body 112 and protrude from the surface of the roller body 112; the insertion groove 111 is located on the side of the support portion 113 opposite to the roller body 112.

[0082] Understandably, the support portion 113 has a certain width and a height along the radial direction of the roller 110. The support portion 113 has a slot on the side opposite to the roller 112 to form an insertion slot 111. The support portion 113 can be perpendicular to the surface of the roller 112, or it can form a non-zero angle with the surface of the roller 112, so that the flexible cleaning component 120 is perpendicular to the surface to be cleaned or has a certain angle with it.

[0083] Optionally, the support portion 113 may not be provided on the surface of the roller 112, and the insertion groove 111 may be directly formed on the surface of the roller 112 so that the flexible cleaning component 120 can be directly inserted into the roller 112.

[0084] As one possible implementation, the roller 112 has two connecting ends 114 at both ends in the axial direction. The connecting ends 114 are coaxially arranged with the roller 112 and have a diameter greater than or equal to the diameter of the roller 112. The two ends of the support portion 113 are respectively connected to the two connecting ends 114. The side of the support portion 113 near the roller 112 has a gap with the surface of the roller 112 to form a ventilation gap 130 between the support portion 113 and the roller 112.

[0085] It should be noted that the diameter of the connecting end 114 is larger than the diameter of the roller 112, and a limiting groove is provided to limit and fix the support part 113. The side of the support part 113 near the roller 112 is connected to the surface of the roller 112. The connection part can be welded or integrally formed. A gap is formed between the support part 113 and the non-connected part of the surface of the roller 112 to allow airflow, which can increase the air flow and improve cleaning efficiency.

[0086] The height of the ventilation gap 130 can be greater than or equal to 1% of the diameter of the roller 110, and less than or equal to 100% of the diameter of the roller 110.

[0087] For example, the ratio of the height of the ventilation gap 130 to the diameter of the roller 110 can be 1%, 5%, 10%, 50%, 100%, etc., and this application embodiment does not make specific limitations.

[0088] See Figure 8 As shown, as one possible implementation, the support portion has at least one through hole 1131, which penetrates the support portion 113, and the through hole 1131 has an angle with the axial direction of the roller 112.

[0089] It is understandable that, while ensuring the support strength of the support part 113, opening the through hole 1131 can increase the gas flow area, improve the airflow path of the whole machine, and reduce hair entanglement; the through hole 1131 can be one or more, and can be square, round, prismatic, etc., and this application embodiment does not specifically limit it.

[0090] It should be noted that the through hole 1131 penetrates the support part 113, and the penetration direction has an angle with the axial direction of the roller 112. The angle is not zero and can be 1°, 5°, 10°, 50°, 90°, etc. The embodiments of this application do not specifically limit this.

[0091] As one possible implementation, the roller brush 100 also includes two end caps 140, which are respectively connected to the two ends of the roller 110 in the axial direction; the two ends of the flexible cleaning element 120 abut against the two end caps 140 respectively.

[0092] It should be noted that the two end caps 140 are disposed on the two connecting ends 114. The end caps 140 and the connecting ends 114 can be connected by threads, snap-fit ​​buckles, etc., and this application embodiment does not make specific limitations. The end caps 140 may be provided with snap-fit ​​holes to snap-fit ​​the cleaning part 121 of the flexible cleaning component 120.

[0093] See Figure 1 , Figure 2 This application embodiment also provides a cleaning device 10, which includes a device body 200 and the aforementioned roller brush 100, with the roller brush 100 rotatably disposed on the device body 200. Through the structure of the roller brush 100, the cleaning device 10 provided in this application embodiment can clean difficult-to-remove hair fibers from soft surfaces to be cleaned, achieving high cleaning efficiency.

[0094] This application provides a roller brush 100 and a cleaning device 10. The roller brush 100 is used in the cleaning device 10 and is rotatably mounted on the cleaning device 10. The roller brush 100 includes a roller 110 and a plurality of flexible cleaning elements 120. The plurality of flexible cleaning elements 120 are circumferentially spaced around the roller 110. Each flexible cleaning element 120 has at least one cleaning portion 121, which protrudes from the surface of the roller 110. In the circumferential direction around the roller 110, the cleaning portions 121 of at least one flexible cleaning element 120 are staggered with the cleaning portions 121 of at least some other flexible cleaning elements 120. The staggered cleaning portions 121 have an overlapping area in the circumferential direction of the roller 110. When the roller brush 100 rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning device 10 can flow between the staggered cleaning portions 121, improving the overall airflow path of the cleaning device 10 and reducing hair entanglement. At the same time, the flexible cleaning elements 120 are detachable, making it easy to remove small amounts of entangled hair.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
