Description

Technical Field

[0001] This application relates to the technical field of cleaning products, and particularly to a roller brush assembly and a cleaning device. Background Art

[0002] Cleaning devices such as mite removers, vacuum cleaners, and floor sweeping robots are commonly used household cleaning devices. Vacuum cleaners and floor sweeping robots can clean the floor, and mite removers can remove dust and worms on the surfaces of mattresses, leather, etc.

[0003] In related technologies, a cleaning device generally includes a housing and a fan unit disposed inside the housing. The airflow generated by the fan unit creates suction at the air intake of the housing. A roller brush may be disposed at a position corresponding to the air intake. The roller brush rolls on the surface to be cleaned to pick up dust and hair, and the dust and hair are sucked into the device through the suction of the air intake to achieve the cleaning function.

[0004] However, during the cleaning process of current cleaning devices, hair is easily wound around the roller brush and cannot be sucked into the device. Summary of the Utility Model

[0005] This application provides a roller brush assembly and a cleaning device to solve the technical problem that during the cleaning process of current cleaning devices, hair is easily wound around the roller brush and cannot be sucked into the device.

[0006] In a first aspect, this application provides a roller brush assembly, which includes a drum and a plurality of flexible cleaning members; the plurality of flexible cleaning members are connected to the drum and are circumferentially spaced apart on the drum; the flexible cleaning members are configured to extend from a first end in the axial direction of the drum to a second end in the axial direction of the drum.

[0007] Among them, each of the plurality of flexible cleaning members includes a first rubber strip portion and a second rubber strip portion distributed at different positions in the axial direction of the drum. The height of the first rubber strip portion in the radial direction of the drum is less than or equal to the height of the second rubber strip portion in the radial direction of the drum; there is a height difference between the first rubber strip portions of at least one flexible cleaning member and the first rubber strip portions of other flexible cleaning members.

[0008] The roller brush assembly provided by the embodiments of this application, through the differential design of the structural dimensions of the flexible cleaning members on the surface of the drum, makes the outer contour diameter of the roller brush assembly narrow at some positions in the axial direction of the drum. When the roller brush assembly rotates, the hair rolled up by the roller brush assembly will gather towards the first rubber strip portion with a lower height, and is more easily sucked into the cleaning device, rather than being wound tighter and tighter on the roller brush assembly, which is more convenient for cleaning the roller brush assembly.

[0009] As an optional implementation manner, the side of the first rubber strip portion of at least one of the plurality of flexible cleaning members facing away from the axis of the drum is higher than the surface of the drum.

[0010] With such arrangement, when the roller brush assembly rotates, the corresponding area of the first rubber strip portion can pat the surface to be cleaned, thereby maintaining a good cleaning effect.

[0011] As an optional embodiment, the side of the first rubber strip portion of at least one of the multiple flexible cleaning members facing away from the axis of the drum is lower than the surface of the drum.

[0012] With such arrangement, when the roller brush assembly picks up the fiber hair, the fiber hair can slide along the surface of the roller and be more easily sucked into the interior of the cleaning device.

[0013] As an optional embodiment, the second rubber strip portions of different flexible cleaning members have the same height.

[0014] With such an arrangement, a flexible cleaning member can continuously tap the surface to be cleaned in a partial area along the axial direction of the drum, thereby ensuring a good cleaning effect.

[0015] As an optional embodiment, each flexible cleaning member includes a first rubber strip portion and two second rubber strip portions, and the two second rubber strip portions are connected to both ends of the first rubber strip portion.

[0016] With such arrangement, the flexible cleaning member can form a structure with high sides and low middle, so that hair is more likely to gather toward the middle of the drum and be sucked into the interior of the cleaning device.

[0017] As an optional embodiment, the roller may include a first roller and two second rollers arranged coaxially, the two second rollers are respectively connected to the two ends of the first roller, and the diameter of the first roller is smaller than the diameter of the second roller; the first rubber strip portion is opposite to the first roller, and the two second rubber strip portions are respectively opposite to the two second rollers.

[0018] With such an arrangement, the roller itself can also have a structure that is thick at both ends and thin in the middle, which is more conducive to the fiber hair gathering toward the middle of the roller brush assembly and preventing the fiber hair from being entangled at both ends of the roller brush assembly.

[0019] As an optional embodiment, a slot is provided on the outer surface of the drum, and the flexible cleaning member is inserted into the slot; the second rubber strip portions all extend to the outside of the slot; and the first rubber strip portion of at least one of the multiple flexible cleaning members is located inside the slot.

[0020] Such an arrangement can improve the reliability of the installation of the flexible cleaning member on the drum and prevent the flexible cleaning member from falling off the drum.

[0021] As an optional embodiment, the slot extends along the axial direction of the drum; or, the slot extends spirally along the circumferential outer wall of the drum.

[0022] With such an arrangement, the flexible cleaning member can contact the cleaned surface in the axial direction of the roller brush assembly, thereby increasing the cleaning range.

[0023] As an alternative embodiment, the roller brush assembly may further include end caps connected to the axial ends of the drum; at least a part of the structure of the end caps blocks the ends of the flexible cleaning members.

[0024] With such an arrangement, the axial sliding of the flexible cleaning members can be restricted, and the installation stability of the flexible cleaning members can be improved.

[0025] In a second aspect, the present application provides a cleaning device, which includes a device main body and the roller brush assembly in the above technical solution. The device main body has a suction port, and the first rubber strip portion of the flexible cleaning member of the roller brush assembly faces the suction port.

[0026] The present application provides a roller brush assembly and a cleaning device. The roller brush assembly includes a drum and a plurality of flexible cleaning members; the plurality of flexible cleaning members are connected to the drum and are circumferentially spaced apart on the drum; the flexible cleaning members are configured to extend from the first end in the axial direction of the drum to the second end in the axial direction of the drum. The plurality of flexible cleaning members all include a first rubber strip portion and a second rubber strip portion distributed at different positions in the axial direction of the drum. The height of the first rubber strip portion in the radial direction of the drum is less than or equal to the height of the second rubber strip portion in the radial direction of the drum; there is a height difference between the first rubber strip portions of at least one flexible cleaning member and the first rubber strip portions of other flexible cleaning members, so that the outer contour diameter of the roller brush assembly narrows at some positions in the axial direction of the drum. The hair rolled up by the roller brush assembly will gather towards the first rubber strip portion with a lower height, and is more easily sucked into the cleaning device, rather than getting more and more entangled on the roller brush assembly, which is more convenient for cleaning the roller brush assembly.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0044] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or maintenance tool comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.

[0045] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0046] A cleaning device generally includes a housing and a blower unit disposed inside the housing. The airflow generated by the blower unit is used to generate suction at the suction port of the housing. A rolling brush may be disposed at a position corresponding to the suction port. The rolling brush is used to roll on the surface to be cleaned to pick up dust and hair, and the dust and hair are sucked into the device through the suction force of the suction port, realizing the cleaning function.

[0047] However, during the cleaning process of current cleaning devices, hair is easily wound around their rolling brushes and cannot be sucked into the device. Taking a mite remover as an example, a mite remover can remove dust and worms on the surfaces of beddings, leather materials, etc. There are usually a lot of hair fibers adhered to the beddings. When the rolling brush of the mite remover rolls on the surface of the bedding, the hair is easily wound around the rolling brush, and as the rolling brush rolls, the wound hair will become tighter and tighter towards both ends of the rolling brush and cannot be sucked away. This will also make the cleaning of the rolling brush time-consuming and laborious.

[0048] To solve the above technical problems, an embodiment of the present application provides a roller brush assembly and a cleaning device. The roller brush assembly is used on the cleaning device, and the structure of the flexible cleaning member of the roller brush assembly is differentially designed. A height difference is formed at different positions of the same flexible cleaning member, and a height difference is formed at some positions of different flexible cleaning members, so that a profile structure with a narrowed diameter is formed at some positions in the axial direction of the roller brush assembly. In this way, when the roller brush assembly rolls up the hair, the hair will not wind and tighten towards both ends of the roller brush assembly, but will wind and move towards the narrowed area as the roller brush assembly rotates, and is sucked into the cleaning device under the action of the suction force inside the cleaning device, reducing the amount of hair wound on the roller brush, improving the cleaning efficiency, and making it more convenient to clean the roller brush after cleaning.

[0050] Refer to Figures 1 to 7 As shown, the present application provides a roller brush assembly 200, which is applied to a cleaning device 10. When the cleaning device 10 performs a cleaning operation, as the cleaning device 10 moves, the roller brush assembly 200 can roll on the surface to be cleaned, and the roller brush assembly 200 can pick up dust, hair and other impurities on the surface to be cleaned, making it easier for the dust, hair and other impurities to be sucked into the cleaning device 10.

[0051] Among them, the roller brush assembly 200 includes a drum 210 and a plurality of flexible cleaning members 220. The plurality of flexible cleaning members 220 are connected to the drum 210 and are circumferentially spaced apart on the drum 210. The flexible cleaning member 220 is configured to extend from the first end in the axial direction of the drum 210 to the second end in the axial direction of the drum 210. When the roller brush assembly 200 rolls on the surface to be cleaned, the flexible cleaning member 220 can play a role in friction and patting the surface to be cleaned, so as to achieve a better cleaning effect.

[0052] In some embodiments, each of the plurality of flexible cleaning members 220 includes a first rubber strip portion 221a and a second rubber strip portion 221b distributed at different axial positions of the drum 210. The height of the first rubber strip portion 221a in the radial direction of the drum 210 is less than or equal to the height of the second rubber strip portion 221b in the radial direction of the drum 210.

[0053] Define the axial direction of the drum 210 as the X direction, that is, the X direction is the axial direction of the rotation of the brush roller assembly 200. The first rubber strip portion 221a and the second rubber strip portion 221b correspond to different positions of the brush roller assembly 200 along the X direction. Define the radial direction of the drum 210 as the Y direction.

[0054] It can be understood that when the cleaning device 10 performs a cleaning operation, the first rubber strip portion 221a and the second rubber strip portion 221b can contact the surface to be cleaned simultaneously or sequentially. As the brush roller assembly 200 rolls, the first rubber strip portion 221a and the second rubber strip portion 221b can pat different positions on the surface to be cleaned and lift up dust and hair.

[0055] Since the height of the first rubber strip portion 221a is less than the height of the second rubber strip portion 221b, the outer contour diameter of the brush roller assembly 200 at the position of the first rubber strip portion 221a is less than the outer contour diameter of the brush roller assembly 200 at the position of the second rubber strip portion 221b. When the brush roller assembly 200 rolls up fiber hair, as the fiber hair is wound, the fiber hair will gather or slide towards the area where the first rubber strip portion 221a with a smaller outer contour diameter is located, and avoid the fiber hair from winding around the rotating shafts at both ends of the brush roller assembly 200 or into the gaps.

[0056] Wherein, when the brush roller assembly 200 rotates around its own axis, the radial cross-section of the formed rotating body is circular. The outer contour diameter of the brush roller assembly 200 refers to the diameter of the radial cross-section of the rotating body formed when the brush roller assembly 200 rotates around its axis.

[0057] In some embodiments, there is a height difference between the first rubber strip portion 221a of at least one flexible cleaning member 220 and the first rubber strip portion 221a of other flexible cleaning members 220. Setting the first rubber strip portion 221a with a relatively low height can reduce the outer contour diameter of the brush roller assembly 200 at the corresponding position, making it easier for dust and fiber hair to be sucked into the interior of the cleaning device 10. And setting the first rubber strip portion 221a with a relatively high height can enable the brush roller assembly 200 to have a structural component at the corresponding position that can effectively pat the surface to be cleaned, ensuring a good cleaning effect.

[0058] For example, among the multiple flexible cleaning members 220, one flexible cleaning member 220 may have a first rubber strip portion 221a with a higher height, while the first rubber strip portions 221a of the other flexible cleaning members 220 have relatively lower heights. While retaining the function of tapping the surface to be cleaned, the outer contour diameter of the roller brush assembly 200 in the middle is minimized as much as possible, so that the limited hair can be more easily sucked into the interior of the cleaning device 10.

[0059] It can be understood that when the roller brush assembly 200 rolls on the surface to be cleaned, the first rubber strip portion 221a of some flexible cleaning parts 220 is lower in height and does not contact the surface to be cleaned, while the first rubber strip portion 221a of some flexible cleaning parts 220 is higher in height and can slap the surface to be cleaned.

[0060] For example, the cleaning device 10 may be provided with a suction port 101, which can generate suction on the side of the roller brush assembly 200, thereby sucking dust and hair picked up by the roller brush assembly 200 into the cleaning device 10. The first rubber strip portion 221a may be opposite the suction port 101. The suction force at positions opposite the suction port 101 is greater than at other positions not opposite the suction port 101. Therefore, fibers and hair that are rolled up by the roller brush assembly 200 and gathered at the position of the first rubber strip portion 221a are more easily sucked into the suction port 101.

[0061] It should be noted that, in the roller brush assembly 200 provided in the embodiment of the present application, the structural dimensions of the flexible cleaning member 220 on the surface of the roller 210 are differentiated in design, so that the outer contour diameter of the roller brush assembly 200 is narrowed at the axial part of the roller 210. When the roller brush assembly 200 rotates, the hair rolled up by the roller brush assembly 200 will gather toward the first rubber strip portion 221a with a lower height, and will be more easily sucked into the cleaning device 10, instead of being entangled tighter and tighter on the roller brush assembly 200, making it easier to clean the roller brush assembly 200.

[0062] Please continue to refer to Figures 1 to 7 In some embodiments, the side of the first rubber strip portion 221 a of at least one of the plurality of flexible cleaning members 220 facing away from the axis of the drum 210 is higher than the surface of the drum 210 .

[0063] It is understood that, at a position corresponding to the first rubber strip portion 221a in the axial direction of the roller 210, the first rubber strip portion 221a of at least one flexible cleaning member 220 can protrude from the surface of the roller 210 in the Y direction. When the roller brush assembly 200 rotates, the corresponding area of the first rubber strip portion 221a can slap the surface to be cleaned, maintaining a good cleaning effect.

[0064] In some embodiments, a side of the first rubber strip portion 221 a of at least one of the plurality of flexible cleaning members 220 facing away from the axis of the drum 210 is lower than the surface of the drum 210 .

[0065] It is understandable that the first rubber strip part 221a is sunk below the surface of the roller 210, and the outer contour diameter of the roller brush assembly 200 can be reduced accordingly. When the roller brush assembly 200 picks up fiber hairs, the fiber hairs can slide along the surface of the roller 210 and are more easily sucked into the cleaning device 10.

[0066] In some embodiments, the heights of the second rubber strip parts 221b of different flexible cleaning members 220 are equal, so that in some areas in the axial direction of the roller 210, the flexible cleaning members 220 can continuously beat the surface to be cleaned, ensuring a good cleaning effect.

[0067] The specific structure of the flexible cleaning member 220 will be described in detail below.

[0068] Please continue to refer to Figures 1 to 7 , in a possible implementation manner, each flexible cleaning member 220 includes a first rubber strip part 221a and two second rubber strip parts 221b, and the two second rubber strip parts 221b are connected to both ends of the first rubber strip part 221a. In this way, the flexible cleaning member 220 can form a structure with higher sides and lower middle, making it easier for hairs to gather towards the middle position of the roller 210 and be sucked into the cleaning device 10.

[0069] It is understandable that the flexible cleaning member 220 has a higher height at both axial ends of the roller 210 and narrows at the middle position in the axial direction of the roller 210, so that the hairs can gather towards the middle of the roller brush assembly 200, avoiding the hairs from winding around both ends of the roller brush assembly 200.

[0070] In some embodiments, the roller 210 may include a first roller body 210a and two second roller bodies 210b arranged coaxially. The two second roller bodies 210b are respectively connected to both ends of the first roller body 210a, and the diameter of the first roller body 210a is smaller than that of the second roller body 210b. The first rubber strip part 221a faces the first roller body 210a, and the two second rubber strip parts 221b respectively face the two second roller bodies 210b.

[0071] It is understandable that the roller 210 itself can also have a structure with thicker ends and thinner middle, which is more conducive to the fiber hairs gathering towards the middle of the roller brush assembly 200 and avoiding the fiber hairs from winding around both ends of the roller brush assembly 200.

[0072] Exemplarily, the second rubber strip part 221b can be arranged to protrude from the surface of the second roller body 210b; the first rubber strip part 221a can protrude from the surface of the first roller body 210a, or the first rubber strip part 221a can be lower than the surface of the first roller body 210a, while maintaining a good cleaning effect, reducing the amount of hairs wound on the roller brush assembly 200.

[0073] Exemplarily, the diameter of the second roller body 210b remains equal along the axial direction of the roller 210. In this way, when the roller brush assembly 200 rolls and cleans on the surface to be cleaned, the frictional force generated between the roller brush assembly 200 and the surface to be cleaned is more balanced, avoiding excessive differences in frictional force at different positions of the roller brush assembly 200 in the axial direction, thereby improving the user's feel when pushing the cleaning device 10 to move.

[0074] It should be noted that the number of the flexible cleaning members 220 can be two, three or more, and the embodiments of the present application do not make specific limitations thereto.

[0075] In some embodiments, a slot 211 is provided on the outer surface of the roller 210, and the flexible cleaning member 220 is inserted into the slot 211, thereby improving the reliability of the installation of the flexible cleaning member 220 on the roller 210 and preventing the flexible cleaning member 220 from falling off the roller 210.

[0076] Among them, the second rubber strip portion 221b extends to the outside of the slot 211, so that the second colloid portion protrudes from the outer surface of the roller 210, thereby patting the surface to be cleaned when the roller brush assembly 200 rotates, achieving a good cleaning effect. The first rubber strip portion 221a of at least one of the plurality of flexible cleaning members 220 is located inside the slot 211, so that the first rubber strip portion 221a is lower than the outer surface of the roller 210, which is beneficial to the gathering of the rolled-up hair towards the middle of the roller 210 and is more easily sucked into the interior of the cleaning device 10.

[0077] Exemplarily, the flexible cleaning member 220 extends along the axial direction of the roller 210. In this way, the flexible cleaning member 220 can contact the surface to be cleaned along the axial direction of the roller brush assembly 200, increasing the cleaning range.

[0078] Exemplarily, the flexible cleaning member 220 spirally extends along the outer circumferential wall of the roller 210. In this way, when the roller brush assembly 200 rolls along the cleaning direction of the cleaning device 10, different positions in the extending direction of the flexible cleaning member 220 can sequentially contact the surface to be cleaned as the roller brush assembly 200 rolls, ensuring that there is space for the air inlet of the air suction port 101 on the surface of the roller brush assembly 200 and improving the suction efficiency of dust and hair.

[0079] In some embodiments, the slot 211 penetrates through both ends of the roller 210 along a first direction. A clamping groove 212 is provided at one end of the slot 211 facing the axis of the roller 210, and the cross-sectional width of the clamping groove 212 is greater than the cross-sectional width of the slot 211. A clamping protrusion 222 is provided at one end of the flexible cleaning member 220 facing the axis of the roller 210, and the clamping protrusion 222 is clamped with the clamping groove 212.

[0080] It is understood that the extension slot 211 of the flexible cleaning member 220 extends from one axial end to the other end of the drum 210. When assembling the flexible cleaning member 220, the flexible cleaning member 220 can be inserted into the slot 211 from the axial end of the drum 210. The engagement protrusion 222 cooperates with the engagement slot 212 to limit the flexible cleaning member 220 in the radial direction of the drum 210, thereby improving the reliability of the flexible cleaning member 220 on the drum 210 and preventing the flexible cleaning member 220 from falling off the drum 210.

[0081] For example, the cross-sectional shape of the engaging groove 212 along the radial direction of the drum 210 matches the cross-sectional shape of the engaging protrusion 222. The cross-sectional shapes of the engaging groove 212 and the engaging protrusion 222 can be square, triangular, circular, elliptical or other polygonal structures, which are not specifically limited in the present embodiment.

[0082] In some embodiments, the roller brush assembly 200 may further include an end cap 230 connected to the axial end of the roller 210. At least a portion of the end cap 230 is disposed at the end of the flexible cleaning member 220, thereby limiting axial sliding of the flexible cleaning member 220 and improving the installation stability of the flexible cleaning member 220.

[0083] It is understandable that after the flexible cleaning member 220 is installed in the slot 211 on the drum 210 , end covers 230 can be installed at both axial ends of the drum 210 , and the end covers 230 can limit the flexible cleaning member 220 in the axial direction of the drum 210 .

[0084] Exemplarily, the end cap 230 may be circular in shape. The end cap 230 may be coaxially arranged with the drum 210, and the coverage area of the end cap 230 is larger than the end area of the drum 210, so as to prevent hair from being rolled into the rollers at both ends of the drum 210.

[0085] For example, the end cap 230 and the end portion of the flexible cleaning member 220 may be engaged with each other, thereby preventing hair from being rolled into the gap between the end cap 230 and the flexible cleaning member 220 .

[0086] Figure 8 This is a schematic structural diagram of the equipment body in the cleaning equipment provided in an embodiment of the present application.

[0087] Please refer to Figure 8 , and combined with Figure 1 An embodiment of the present application provides a cleaning device 10, which includes a device body 100 and a roller brush assembly 200 in the above technical solution. The device body 100 has an air suction port 101, and the first rubber strip portion 221a of the flexible cleaning member 220 of the roller brush assembly 200 is opposite to the air suction port 101.

[0088] The device body 100 may include a base 110 and a cover 120. The base 110 has a receiving groove 111, in which the roller brush assembly 200 is rotatably disposed. The cover 120 covers the notch of the receiving groove 111. A dirt inlet trough 121 is provided on the side of the cover 120 away from the air inlet 101.

[0089] It is understandable that the notch of the accommodating groove 111 faces the bottom of the base 110, and the cover 120 is arranged below the base 110, so that when the cleaning device 10 is in use, the flexible cleaning member 220 can face the surface to be cleaned below the base 110.

[0090] The dirt inlet trough 121 is located at the front side of the receiving tank 111 along the cleaning direction of the cleaning device 10, that is, the dirt inlet trough 121 is located at the front side of the device body 100 along the Y direction. When the cleaning device 10 performs a cleaning operation, the dirt inlet trough 121 can guide the hair and dust brought up by the roller brush assembly 200, thereby improving cleaning efficiency.

[0091] Exemplarily, the cover plate 120 may cover the area where the end caps 230 at both ends of the roller brush assembly 200 are located, thereby preventing hair from being caught in the rotating shafts at both ends of the roller brush assembly 200 .

[0092] For example, the cover 120 can be connected to the base 110 by a snap fastener, or by fasteners such as bolts. The cover 120 can be detachable relative to the base 110, or the cover 120 can be rotatably connected to the base 110 and can be rotated to open and close, which is not specifically limited in the present embodiment.

[0093] In some embodiments, the cover plate 120 may have an opening, through which the roller brush assembly 200 at least partially protrudes out of the accommodating groove 111. The cover plate 120 may have at least two retaining ribs 130 disposed thereon, spaced apart along the first direction, with the ends of the retaining ribs 130 respectively connected to the two sides of the opening.

[0094] It can be understood that the retaining rib 130 is arranged across the opening, and the retaining rib 130 can divide the opening into multiple small areas. On the one hand, this will not affect the contact between the flexible cleaning member 220 on the roller brush assembly 200 and the external surface to be cleaned, and dust and hair can smoothly enter the suction port 101 under the drive of the roller brush assembly 200. On the other hand, when cleaning flexible surfaces to be cleaned such as bed sheets, the cloth can be prevented from being sucked into the roller brush, thereby ensuring the smoothness of the cleaning process.

[0095] In some embodiments, the retaining rib 130 is opposite to the air suction port 101. Since the suction force on the surface to be cleaned is greatest when it is opposite to the air suction port 101, the retaining rib 130 can be positioned opposite to the first cleaning section, that is, the retaining rib 130 is positioned opposite to the air suction port 101, thereby better preventing the cloth from being sucked into the roller brush.

[0096] First, the application scenarios of the cleaning device 10 provided in the embodiments of the present application will be exemplarily described below.

[0097] The cleaning device 10 provided in the embodiments of the present application is a cleaning tool with a roller brush structure. Specifically, the product types of the cleaning device 10 in the embodiments of the present application may include, but are not limited to, mite removers, vacuum cleaners, floor sweepers, floor sweeping robots, etc. According to different product types, the cleaning device 10 provided in the embodiments of the present application can be used to clean floors, clothes, quilts, sofa furniture, etc. The embodiments of the present application do not make specific limitations on this.

[0098] The embodiments of the present application provide a roller brush assembly and a cleaning device. The roller brush assembly includes a drum and a plurality of flexible cleaning members; the plurality of flexible cleaning members are connected to the drum and are circumferentially spaced apart on the drum; the flexible cleaning members are configured to extend from a first end in the axial direction of the drum to a second end in the axial direction of the drum. The plurality of flexible cleaning members each include a first rubber strip portion and a second rubber strip portion distributed at different positions in the axial direction of the drum. The height of the first rubber strip portion in the radial direction of the drum is less than or equal to the height of the second rubber strip portion in the radial direction of the drum; there is a height difference between the first rubber strip portions of different flexible cleaning members, so that the outer contour diameter of the roller brush assembly narrows at some positions in the axial direction of the drum. The hair rolled up by the roller brush assembly will gather towards the first rubber strip portion with a lower height, and is more easily sucked into the cleaning device, rather than becoming more and more tightly wound on the roller brush assembly, which is more convenient for cleaning the roller brush assembly.

[0099] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
