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 problem of difficult-to-clean hair entangled in roller brushes.

[0006] In a first aspect, this application provides a roller brush for use in a cleaning device, wherein the roller brush is rotatably disposed on the cleaning device; the roller brush includes a roller, the roller including a roller body and at least one bracket; the bracket is detachably connected to the side of the roller body.

[0007] The support is provided with ventilation holes that penetrate the support in a first direction; the ventilation holes are configured to form an airflow channel for airflow to pass through the roller brush; wherein the first direction is at an angle to the axial direction of the roller.

[0008] The roller brush provided in this application includes a roller body and a bracket detachably connected to the side of the roller body. The bracket is provided with ventilation holes, which can form an airflow path on the roller body to improve the overall airflow path of the cleaning equipment, reduce the impact of inward suction on hair fibers, and thus improve the situation of hair fibers getting tangled in the roller brush. In addition, when hair is tangled, the bracket can be removed for cleaning, which improves the convenience of hair fiber cleaning.

[0009] As an optional implementation, the support is arranged along the axial direction of the roller; there are multiple ventilation holes, which are spaced apart along the extension direction of the support.

[0010] This configuration increases the number of airflow paths passing through the support, thus improving the cleaning effect.

[0011] As an alternative implementation, the surface of the roller is provided with a connecting structure, and the support abuts against the connecting structure; the connecting structure is configured to limit the support along the radial direction of the roller.

[0012] This design prevents radial displacement of the roller when the support is connected to the roller, thus improving connection stability.

[0013] As an optional implementation, the connection structure includes multiple snap-fits, all of which extend vertically on the surface of the roller; the multiple snap-fits are respectively disposed on both sides of the bracket and engage with the bracket.

[0014] This design allows for pairing and locking with the bracket on both sides using multiple clips, improving connection stability and support.

[0015] As an alternative implementation, the buckle is positioned opposite to the ventilation hole; the buckle has a protrusion facing the bracket, which engages within the ventilation hole.

[0016] This design, through the snap-fit ​​between the protrusion and the ventilation hole, allows for a fixed connection between the bracket and the roller without affecting the function of the ventilation hole, thus improving the compactness of the roller brush structure.

[0017] As an alternative implementation, the upper edge of the protrusion has a first guide slope, and the lower edge of the bracket has a second guide slope.

[0018] During the engagement of the bracket and the buckle, the first guide slope and the second guide slope abut against each other, and the bracket compresses the buckle to deform elastically, so that the protrusion is inserted into the ventilation hole.

[0019] This design allows for a smoother and more stable snap-fit ​​process through the two beveled surfaces, improving ease of installation.

[0020] As an alternative implementation, the buckle has a protrusion facing the bracket, and the bracket has bosses on both sides; the protrusion is engaged with the upper edge of the bosses.

[0021] This design, through the engagement of the protrusion and the boss, improves connection stability.

[0022] As an optional implementation, the roller includes a cylindrical portion and two coaxially arranged connecting ends, which are respectively connected to the two ends of the cylindrical portion in the axial direction; the diameter of the connecting ends is greater than or equal to the diameter of the cylindrical portion; the outer edge of the connecting ends is provided with a limiting groove, and the two ends of the bracket are respectively placed in the limiting grooves of the connecting ends at both ends of the roller.

[0023] The lower edge of the support has a gap with the surface of the cylindrical part to form an airflow channel for airflow to pass through the roller brush.

[0024] With this configuration, the limiting groove can restrict the movement of the bracket along the roller axis, further improving connection stability; and the airflow channel can increase the ventilation area of ​​the roller brush, improving airflow efficiency.

[0025] As an optional implementation, the connection structure includes a slot that extends axially from one end of the roller to the other; the width of the slot opening on the sidewall of the roller is smaller than the width of the slot inside; and a bracket is inserted into the slot.

[0026] This design prevents the support from moving radially along the roller after it is connected to the roller, thus improving connection stability.

[0027] As an alternative implementation, the roller brush also includes a flexible cleaning element that is connected to the support.

[0028] With this configuration, the flexible cleaning component can be connected to or detached from the roller via a bracket, making it easy to clean the hair fibers entangled on the flexible cleaning component.

[0029] As an alternative implementation, the top side of the bracket has a insertion groove extending along its length, into which the flexible cleaning component is inserted; or, the flexible cleaning component and the bracket are integrally formed.

[0030] This design ensures that the flexible cleaning component cleans along the entire length of the roller, avoiding blind spots in cleaning.

[0031] As an optional implementation, there are multiple supports, which are spaced apart circumferentially on the roller.

[0032] This setup allows multiple supports to work together, improving cleaning efficiency and effectiveness.

[0033] As an optional implementation, the roller brush also includes two end caps, which are respectively connected to both ends of the roller axial direction; the two ends of the bracket abut against the two end caps respectively.

[0034] This design restricts the movement of the support along the roller axis, improving the connection stability between the support and the roller.

[0035] 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.

[0036] The cleaning equipment provided in this application cleans the ground with the aforementioned roller brush, which can effectively remove hair fibers from the surface to be cleaned and improve the cleaning effect.

[0037] The roller brush provided in this application is used in cleaning equipment and is rotatably mounted on the cleaning equipment. The roller brush includes a roller, which includes a roller body and at least one support. The support is detachably connected to the side of the roller body. The support has ventilation holes that penetrate the support in a first direction. The ventilation holes are configured to form an airflow channel for airflow to pass through the roller brush. The first direction forms an angle with the axial direction of the roller. When the roller brush rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning equipment can flow through the ventilation holes on the support, improving the overall airflow path of the cleaning equipment. This prevents hair fibers from getting tangled on the roller brush, and the support is easy to disassemble, making disassembly and cleaning more convenient when a small amount of hair is tangled and stuck.

Therefore, they should not be construed as limitations on this application.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Cleaning devices such as mite removers, vacuum cleaners, and robotic vacuum cleaners are commonly used in households. They can clean smooth surfaces like floors, as well as soft surfaces like mattresses and leather. These devices typically consist of a casing and a fan unit inside. The airflow generated by the fan unit creates suction at the air inlet on the casing. A roller brush can be positioned opposite the air inlet; the brush rolls across the surface being cleaned, picking up dust and hair, which is then drawn into the device by the suction, thus achieving the cleaning function.

[0068] 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.

[0069] To address the aforementioned technical problems, this application provides a roller brush and a cleaning device. The roller brush features a support structure with ventilation holes. When the roller brush rotates to clean the surface, the negative pressure airflow generated by the cleaning device can flow through the ventilation holes on the support, improving the overall airflow path of the cleaning device. This prevents hair fibers from getting tangled on the roller brush, and the support is easy to disassemble. When a small amount of hair gets tangled and stuck, disassembly and cleaning are more convenient.

[0070] The following is an example illustrating the application scenarios of the roller brush and cleaning equipment provided in the embodiments of this application.

[0071] 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 types of the cleaning equipment in this application embodiment may include, but are 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, as well as smooth surfaces such as floor tiles. This application embodiment does not make any specific limitations in this regard.

Figure 8 The image shows a side view of the bracket and flexible cleaning component provided in Embodiments 1 and 2 of this application.

[0073] See Figures 1 to 8 As shown, Embodiment 1 of this application provides a roller brush 100, which is applied to a cleaning device 10 and rotatably disposed on the device body 200. When the cleaning device 10 cleans the surface to be cleaned, the roller brush 100 contacts the surface to be cleaned. 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.

[0074] The roller brush 100 provided in this application is rotatably mounted on the cleaning device 10. The roller brush 100 includes a roller 110, which includes a roller body 112 and at least one bracket 124. The roller body 112 is rotatably connected to the main body of the cleaning device 10. The bracket 124 is detachably connected to the side of the roller body 112. To improve cleaning efficiency, multiple brackets 124 can be provided. When the cleaning device 10 is cleaning, the roller body 112 rotates, causing multiple brackets 124 to rotate. The multiple brackets 124 contact the surface to be cleaned in sequence. By rubbing and patting the surface to be cleaned, the attached dust and hair fibers are picked up. When hair fibers are wrapped around the roller brush 100, the bracket 124 can be removed from the roller body 112 for cleaning, which is more convenient.

[0075] The bracket 124 provided in this embodiment of the application has a ventilation hole 121, which penetrates the bracket 124 in a first direction; the ventilation hole 121 is configured to form an airflow channel for airflow to pass through the roller brush 100; wherein, the first direction has an angle with the axial direction of the roller 110.

[0076] It is understandable that a fan can be installed on the cleaning device 10 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 dust and hair fibers from the surface to be cleaned into the cleaning device 10. By setting ventilation holes 121 on the bracket 124, the airflow path of the whole machine can be improved, and hair fibers can be prevented from getting tangled in the roller brush 100.

[0077] It should be noted that the ventilation hole 121 penetrates the bracket 124 in the first direction and has an angle with the axis of the roller 110, so that the ventilation hole 121 can connect the inside of the cleaning device 10 and the external environment. The first direction has a non-zero angle with the axis of the roller 110. 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 air path formed by the ventilation hole 121 on the other hand. This allows the periphery of the roller brush 100 and the ventilation hole 121 of the bracket 124 to form an air path for airflow, improving the air volume and airflow efficiency, thereby preventing hair fibers from remaining on the surface to be cleaned.

[0078] For example, the first direction has an angle with the axial direction of the roller 110. The angle value includes, but is not limited to, 1°, 2°, 10°, 20°, 30°, 45°, 60°, 89°, 90°, etc. The embodiments of this application do not specifically limit this.

[0079] Understandably, 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 through the ventilation hole 121. The support 124 on the side of the roller 112 can still provide a good cleaning effect of friction and tapping on the surface to be cleaned. At the same time, the direction of the suction force generated by the air inlet causes some airflow to bypass the outside of the roller brush 100, but some airflow can pass directly through the ventilation hole 121, reducing wind resistance and improving the overall airflow path of the cleaning device 10. This prevents hair fibers from getting tangled on the roller brush 100, making it easier for hair fibers to be sucked into the cleaning device 10 and improving the cleaning effect.

[0080] In one possible implementation, the support 124 is arranged along the axial direction of the roller 110; there are multiple ventilation holes 121, which are spaced apart along the extension direction of the support 124.

[0081] It is understood that the bracket 124, arranged along the axial direction of the roller 110, can cover the cleaning area and avoid any missed spots; the multiple ventilation holes 121, arranged at intervals along the extension direction of the bracket 124, can increase the ventilation area along the length of the roller brush 100 and improve airflow efficiency. The shape of the ventilation holes 121 can be square, rectangular, round, elliptical, or other shapes. This application embodiment does not specifically limit this. The number of ventilation holes 121 is set according to their shape to achieve a certain gas flow rate. Each ventilation hole 121 can be understood as forming an air path. Multiple airflow paths can disperse the airflow passing through the roller brush 100, reducing wind resistance and noise generated when the roller brush 100 rotates for cleaning.

[0082] For example, the number of ventilation holes 121 can be 2, 3, 4, 5, etc., and the multiple ventilation holes 121 can be arranged at equal intervals or at unequal intervals. This application embodiment does not specifically limit this.

[0083] In one possible implementation, the surface of the roller 112 is provided with a connecting structure, and the support 124 abuts against the connecting structure; the connecting structure is configured to limit the support 124 radially along the roller 110.

[0084] It should be noted that the roller 112 is connected to the bracket 124 through the surface connection structure. The connection structure can be of various forms, which can make it easier to disassemble or install the bracket 124. The connection structure can limit the bracket 124 in the radial direction of the roller 110, so that the bracket 124 will not be displaced in the radial direction of the roller 110 after installation, thus affecting the cleaning effect. The bracket 124 is limited in the axial direction of the roller 110 after installation through the connection ends 113 at both ends of the roller 112.

[0085] In one possible implementation, the connection structure includes multiple snap fasteners 111, all of which extend vertically on the surface of the roller 112; the multiple snap fasteners 111 are respectively disposed on both sides of the bracket 124 and engage with the bracket 124.

[0086] It is understood that the connection structure on the surface of the rolling body 112 consists of multiple snap fasteners 111. Each bracket 124 has multiple snap-fit ​​points along its length. Each snap-fit ​​point has two snap fasteners 111 on both sides to snap the bracket 124. The snap fasteners 111 and the axial direction of the rolling body 112 have a certain angle. The size of the angle can be determined according to the actual snap-fit ​​effect. The length of the snap fasteners 111 is greater than or equal to 1% of the axial length of the rolling body 112 and less than or equal to 90% of the axial length of the rolling body 112. By snapping the bracket 124 with multiple sets of snap fasteners 111, the bracket 124 can be fixed to the surface of the rolling body 112.

[0087] For example, the number of buckles 111 can be 1, 2, 3, etc., and multiple buckles 111 can be arranged at equal intervals or at unequal intervals. This application embodiment does not specifically limit this.

[0088] For example, the ratio of the length of the buckle 111 to the axial length of the roller 112 can be 1%, 5%, 10%, 50%, 90%, etc., and this application embodiment does not specifically limit it.

[0089] In one possible implementation, the buckle 111 is disposed opposite to the ventilation hole 121; the buckle 111 has a protrusion 1111 facing the bracket 124, the protrusion 1111 being engaged in the ventilation hole 121.

[0090] It is understood that the buckle 111 extends vertically along the surface of the roller 112 to the height of the vent, and is embedded in the corresponding vent through the protrusion 1111 to fix the bracket 124. During fixation, the buckles 111 are engaged by a pair of buckles 111, with the protrusions 1111 of the pair of buckles 111 facing each other and embedded in the vent hole 121, forming a double fixation.

[0091] In one possible implementation, the upper edge of the protrusion 1111 has a first guide slope 1111a, and the lower edge of the bracket 124 has a second guide slope 122.

[0092] During the engagement of the bracket 124 and the buckle 111, the first guide slope 1111a abuts against the second guide slope 122, and the bracket 124 presses the buckle 111 to deform elastically so that the protrusion 1111 is inserted into the ventilation hole 121.

[0093] It should be noted that each ventilation hole 121 of the bracket 124 requires at least one pair of snap fasteners 111 for engagement. The paired snap fasteners 111 form an annular buckle with a certain gap in the middle. The first guide slope 1111a and the second guide slope 122 have the same inclination angle. The inclination angle can be selected according to the actual engagement effect, and this embodiment does not impose a specific limitation. The bottom of the bracket 124 may be provided with an arc-shaped engagement part protruding from the main body of the bracket 124. When engaging, the first guide slope 1111a and the second guide slope 122 engage. Then, the bracket 124 is pressed downward, causing the two buckles 111 to undergo elastic deformation. The two protrusions 1111 move away from each other. When the buckles 111 are at their maximum deformation, the distance between the two protrusions 1111 is equal to the length of the arc-shaped locking part at the bottom of the bracket 124. The arc-shaped locking part can be inserted into the ring buckle through the gap between the two protrusions 1111. The two protrusions 1111 are embedded in the ventilation port to complete the locking. By locking multiple ventilation holes 121 with multiple sets of buckles 111, the bracket 124 can be fixed on the surface of the roller 112.

[0094] It is understandable that a gap may be left between the arc-shaped locking part at the bottom of the bracket 124 and the main body of the bracket 124. The width of the gap may be the same as the thickness of the protrusion 1111, so that the protrusion 1111 can be locked between the arc-shaped locking part and the main body of the bracket 124 to prevent the bracket 124 from swaying radially on the roller 112. With this arrangement, a gap may be left between the surface of the bracket 124 and the surface of the roller 112 to allow airflow.

[0095] Optionally, some ventilation holes 121 of the bracket 124 may not be equipped with clips 111 for snap-fit, so as to increase the cross-sectional area of ​​the ventilation holes 121. Some ventilation holes 121 may be equipped with one set of clips 111 or multiple sets of clips 111 for snap-fit.

[0096] Figure 9 This is a schematic diagram of the roller brush structure provided in Embodiment 2 of this application; Figure 10 This is a front view of the roller brush provided in Embodiment 2 of this application; Figure 11 for Figure 10 A cross-sectional view at position BB in the middle; Figure 12 This is a structural schematic diagram of the bracket and flexible cleaning component provided in Embodiment 2 of this application.

[0097] Reference Figures 7 to 12 As shown, this application provides a second embodiment, in which the bracket 124 is fixed in a different way.

[0098] In the second embodiment, the buckle 111 has a protrusion 1111 facing the bracket 124, and the bracket 124 has protrusions 123 on both sides; the protrusion 1111 is engaged with the upper edge of the protrusion 123.

[0099] It is understandable that there is a gap between the protrusions 1111. The width of the gap between the protrusions 1111 is greater than the width of the bracket 124 and less than the distance between the two ends of the boss 123, so that the protrusions 1111 can be locked on the upper edge of the boss 123 to limit the cleaning assembly radially along the roller 112.

[0100] Optionally, multiple buckles 111 can be provided along the length of the roller 112. The number of buckles 111 corresponds to the number of bosses 123. The multiple buckles 111 are arranged in parallel. When the bracket 124 is engaged, the bosses 123 can be inserted into the buckles 111 from the side of the buckles 111, so that the protrusions 1111 are engaged on the upper edge of the bosses 123.

[0101] In this embodiment, the roller 112 includes a cylindrical portion 116 and two coaxially arranged connecting ends 113, which are respectively connected to the two ends of the cylindrical portion 116 in the axial direction. The diameter of the connecting end 113 is greater than or equal to the diameter of the cylindrical portion 116. The outer edge of the connecting end 113 is provided with a limiting groove 1131, and the two ends of the bracket 124 are respectively placed in the limiting grooves 1131 of the connecting ends 113 at both ends of the roller 112.

[0102] It is understood that during installation, the bracket 124 is secured by snap-fit ​​111 to achieve radial fixation along the roller 112. Then, connecting ends 113 are installed at both ends of the roller 112, and the bracket 124 is snapped into the limiting groove 1131 of the connecting end 113, thus achieving axial fixation of the bracket 124 along the roller 112. The diameter of the connecting end 113 is greater than or equal to the diameter of the cylindrical part 116, which can play the role of axial positioning and enhancing structural strength. The connecting end 113 and the cylindrical part 116 can be connected by thread, snap-fit, etc., which are not specifically limited in this embodiment.

[0103] It should be noted that in the above two embodiments, the lower edge of the bracket 124 and the surface of the cylindrical part 116 have an airflow gap 130 to form an airflow channel for airflow to pass through the roller brush 100. The height of the airflow gap 130 is greater than or equal to 1% of the diameter of the roller 112 and less than or equal to 100% of the diameter of the roller 112. The lower edge of the bracket 124 is also provided with a support part 126, which connects the lower edge of the bracket 124 and the cylindrical part 116. Through the support part 126, the buckle 111 and the connecting end 113, the bracket 124 completes the connection with the roller 112.

[0104] For example, the ratio of the height of the airflow gap 130 between the lower edge of the bracket 124 and the surface of the cylindrical portion 116 to the diameter of the roller 112 can be 1%, 5%, 10%, 50%, 100%, etc., and this application embodiment does not make specific limitations.

[0106] Reference Figures 13 to 18 This application provides Embodiment 3, which fixes the bracket 124 in a different way.

[0107] In this embodiment, the connecting structure includes a slot 114, which extends axially from one end of the roller 112 to the other end. The slot width of the slot 114 located on the side wall of the roller 112 is smaller than the inner width of the slot 114. The lower edge of the bracket 124 is provided with a plug-in part, the shape of which corresponds to the slot 114. During installation, the plug-in part is inserted into the slot 114 at one end of the roller 112 to fix the bracket 124 radially along the roller 112.

[0108] In one possible implementation, the roller brush 100 also includes a flexible cleaning element 125, which is connected to the bracket 124.

[0109] It is understood that the bracket 124 is used to connect the flexible cleaning component 125 and the roller 112. The bracket 124 and the roller 112 can be connected and fixed by the buckle 111 and the slot 114 in the above three embodiments. The flexible cleaning component 125 and the bracket 124 can be connected and fixed by the buckle 111 and the keyway connection structure. The flexible cleaning component 125 is used to contact the surface to be cleaned. The rotation of the roller 112 can drive the flexible cleaning component 125 to wipe and pat the surface to be cleaned, so as to pick up dust and hair fibers.

[0110] The flexible cleaning component 125 undergoes elastic deformation when compressed, which can loosen the rolled-up fibers and prevent hair from getting tangled on the roller brush 100.

[0111] In some embodiments, the roller 112 may be used directly as a roller brush 100 to clean the surface to be cleaned without the need to connect the bracket 124 and the flexible cleaning component 125. For example, the roller 112 may be wrapped with a cloth or bristles to clean the surface to be cleaned.

[0112] In some embodiments, the bracket 124 is arranged along the axial direction of the roller 112, which can ensure that the flexible cleaning element 125 cleans along the entire length of the roller 112 and avoids cleaning blind spots.

[0113] Optionally, the top side of the bracket 124 has a insertion groove 127 extending along its length, and the flexible cleaning component 125 is inserted through the insertion groove 127, or the flexible cleaning component 125 and the bracket 124 can be integrally formed.

[0114] In some embodiments, there are multiple supports 124, which are arranged circumferentially at intervals on the roller 112.

[0115] It should be noted that multiple supports 124 are evenly distributed around the circumference of the roller 112, and the ventilation holes 121 of two adjacent supports 124 can be set correspondingly or staggered.

[0116] In some embodiments, the roller brush 100 further includes two end caps 115, which are respectively connected to the two ends of the roller 112 in the axial direction; the two ends of the bracket 124 abut against the two end caps 115 respectively.

[0117] It should be noted that two end caps 115 are disposed on two connecting ends 113. The end caps 115 and the connecting ends 113 can be connected by threads, snap-fit ​​buckles, etc., and this application embodiment does not make specific limitations. The end caps 115 may be provided with snap-fit ​​holes 1151 to snap-fit ​​the flexible cleaning part.

[0118] The roller brush 100 provided in this application is used in a cleaning device 10, and the roller brush 100 is rotatably mounted on the cleaning device 10. The roller brush 100 includes a roller 110, the roller 110 includes a roller body 112 and at least one bracket 124, the bracket 124 being detachably connected to the side of the roller body 112; the bracket 124 is provided with a ventilation hole 121, the ventilation hole 121 penetrating the bracket 124 in a first direction; the ventilation hole 121 is configured to form an airflow channel for airflow to pass through the roller brush 100; wherein, the first direction forms an angle with the axial direction of the roller body 112. 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 through the ventilation hole 121 on the bracket 124, improving the overall airflow path of the cleaning device 10, preventing hair fibers from getting tangled on the roller brush 100, and the bracket 124 is easy to disassemble, making disassembly and cleaning more convenient when a small amount of hair is tangled and stuck.
