The present application will be further described in detail below in conjunction with the drawings and specific embodiments. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0054] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.

[0055] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature being "on" the second feature may mean that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium.

[0056] In the description of this specification, the descriptions referring to terms such as "some embodiments", "exemplarily", "specific", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine the different embodiments or examples described in the present application and the features of different embodiments or examples.

[0057] In the related art, during cleaning by a cleaning device, hair will wind around the surface of the brush body, which may cause equipment failure and lead to operation stop, or the hair stays on the surface of the brush body and affects the cleaning effect.

[0058] In view of this, please refer to Figures 1 - 2 , embodiments of the present application provide a roller brush assembly 100. The roller brush assembly 100 can be used in cleaning devices such as a floor sweeper to clean garbage, and the garbage includes but is not limited to hair, dust, debris, and the like. The roller brush assembly 100 includes a brush body 10 and a driving wheel set 20. The brush body 10 is used to clean garbage such as dust, debris, and hair on the surface to be cleaned. Under the driving action of the driving wheel set 20, the brush body 10 rolls relative to the surface to be cleaned, and collects the dust, debris, hair and other garbage on the surface to be cleaned. The brush body 10 drives the garbage to be sucked into the dust collection box of the cleaning device under the suction effect.

[0059] The brush body 10 includes a cylinder body 11 and blades 12. The cylinder body 11 and the blades 12 can be integrally formed or separately manufactured and then installed together. The blades 12 are soft blades, and the blades 12 extend from one end of the outer wall 112 of the cylinder body 11 along the axial direction of the cylinder body 11 to the other end, and the extending trends of the plurality of blades 12 are the same. The plurality of blades 12 are arranged at intervals along the circumferential direction of the outer wall 112 of the cylinder body 11. The cylinder body 11 is sleeved on the driving wheel set 20, and the cross-section of the cylinder body 11 can form a circular shape or a runway shape according to the contact surface with the driving wheel set 20. The driving wheel set 20 can drive the cylinder body 11 to rotate, and then drive the blades 12 to rotate for cleaning. For example, the driving wheel set 20 and the cylinder body 11 can be driven by gear meshing, or by the friction force between the contact surfaces of the driving wheel set 20 and the cylinder body 11.

[0060] The blade 12 is generally a flat body with a relatively thin thickness, which can be 0.4 - 1.0 mm, such as 0.4 mm, 0.6 mm, 0.8 mm or 1.0 mm. The thickness of the blade 12 refers to the dimension of the blade 12 along the rotation direction. The blade 12 is made of a soft blade, such as TPU (Thermoplastic polyurethanes), PVC (Polyvinylchloride) or PU (Poly Urethane), etc. The soft material has strong flexibility and elasticity, can deform under the action of external force, and can return to its original state after the external force disappears. For example, the material of the blade 12 can be TPU. TPU has excellent wear resistance and elasticity. Its wear resistance is excellent, with low abrasion loss and good elasticity, and can quickly return to its original state after the external force disappears. Exemplarily, the hardness of the blade 12 can be 60 - 90 HA, where HA refers to the unit of Shore hardness type A. The material of the cylinder 11 can be the same as or different from that of the blade 12. When the cylinder 11 and the blade 12 are integrally formed, the same soft material can be used, such as both being TPU.

[0061] In this way, when cleaning, the blade 12 can deform following the movement of the cylinder 11, forming a tendency to swing. After the flat blade 12 deforms, the contact area with the surface to be cleaned is increased, the frictional effect on the garbage is increased, and the cleaning effect is improved. At the same time, multiple blades 12 swing together, and the front and rear blades 12 continuously clean, which can enhance the cleaning effect of stubborn stains. The multiple blades 12 are arranged at intervals along the circumferential direction. In the case of the deformation of the blade 12, larger particles of garbage can be clamped between adjacent blades 12, improving the cleaning effect on large particle garbage. When the electric power allocated to the rotary brush assembly 100 is small, due to the good cleaning effect of the soft blade, part of the cleaning requirements can still be met at low power.

[0062] The multiple blades 12 are arranged at intervals along the circumferential direction of the outer wall 112 of the cylinder 11. The circumferential direction of the outer wall 112 refers to the annular direction formed by the cross-section of the outer wall 112 along the direction perpendicular to the axial direction of the cylinder 11. In this way, a dust collection space can be formed between two adjacent blades 12 to collect garbage such as dust, debris, and hair on the contact surface.

[0063] Exemplarily, please refer to Figures 3 - 5 , the multiple blades 12 are arranged in parallel, and each blade 12 can be formed in a straight arrangement to push the garbage in parallel. In this way, the manufacturing difficulty can be reduced and the production cost can be reduced.

[0064] In some embodiments not shown, the blades are arranged in parallel, and each blade can also be formed in a wavy line, a spiral line or a V-shaped line arrangement. The wavy line blade can improve the clamping effect of the blade on garbage such as large granular debris, and reduce the possibility of the garbage falling during the movement after being clamped by the blade. The spiral line blade can push the garbage to one side. The V-shaped line blade can move the garbage from both sides to the sharp corner in the middle.

[0065] The heights of the blades 12 can be the same or different. The height of the blade 12 refers to the length between the end where the blade 12 is connected to the cylinder 11 and the end far from the cylinder 11. In some embodiments, please refer to Figure 4 and Figure 5 , all the blades 12 on the brush body 10 have the same height. When the surface to be cleaned is hard or the garbage is mostly large granular, the same length of the blades 12 can increase the cleaning strength and improve the cleaning effect.

[0066] In some embodiments, please refer to Figure 3 , the heights of the blades 12 on the brush body 10 are not the same. The blade 12 includes a first blade 121 and a second blade 122. The height of the first blade 121 is greater than that of the second blade 122. The first blade 121 and the second blade 122 are alternately arranged according to a preset number. The combined setting of the first blade 121 and the second blade 122 can perform more effective cleaning on garbage and dust of different sizes. The first blade 121 can penetrate into gaps and corners to facilitate grasping larger garbage and debris. The second blade 122 located between adjacent first blades 121 can play a supporting role. A dust collection space can be formed between the first blades 121. After the garbage enters the dust collection space, it then rolls and moves along with the cylinder 11 to the dust suction part of the cleaning device. Under the supporting action of the second blade 122, it is convenient to sweep the garbage into the space between the first blades 121, thereby improving the cleaning effect. And it can reduce the possibility of garbage such as hair winding around the outer circumference of the brush body 10.

[0067] The preset number of alternations of the first blade 121 and the second blade 122 is not limited. For example, please refer to Figure 3 , it can be the repeated alternation of a single first blade 121 and a single second blade 122. In some other embodiments not shown, it can be the repeated alternation of a single first blade 121 and multiple second blades 122; or the repeated alternation of multiple first blades 121 and a single second blade 122; or the repeated alternation of multiple first blades 121 and multiple second blades 122.

[0068] In some embodiments, a plurality of blades 12 are arranged in parallel, and the ratio of the height dimension to the thickness dimension of at least part of the blades 12 is greater than or equal to 10, such as 10, 11 or 12. When all the blades 12 have the same height, the ratio of the height dimension to the thickness dimension of all the blades 12 can be greater than or equal to 10. For example, the ratio of the height dimension to the thickness dimension of each blade 12 is 10, 11 or 12. When the blade 12 includes a higher first blade 121 and a lower second blade 122, the ratio of the height dimension to the thickness dimension of the first blade 121 is greater than or equal to 10, such as 10, 11 or 12. By reasonably adjusting the height-to-thickness ratio of the blade 12, brush bodies 10 of different models are produced to meet the cleaning requirements of different sites and improve the cleaning effect of different sites.

[0069] In some embodiments, a plurality of blades 12 are arranged in parallel, and a single first blade 121 and a single second blade 122 are arranged alternately in a repeating pattern. The distance between two adjacent first blades 121 is 5 - 10 mm, such as 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm. The second blade 122 is located between two adjacent first blades 121. Exemplarily, the distances between the second blade 122 and the two adjacent first blades 121 are equal. In this way, the deformation of the first blade 121 can be better controlled, which can not only improve the cleaning effect, but also make the supporting force of the second blade 122 more uniform, thus enhancing the user experience.

[0070] In some embodiments, please refer to Figures 3 - 5 , the brush body 10 further includes a limiting member 13 disposed on the inner wall 111 of the cylinder 11. The limiting member 13 is arranged along the circumferential direction of the inner wall 111 of the cylinder 11 to limit the brush body 10 in the axial direction of the cylinder 11.

[0071] The limiting member 13 is arranged along the circumferential direction of the inner wall 111 of the cylinder 11, which can improve the limiting effect on the cylinder 11 and reduce the possibility of displacement of the cylinder 11 due to axial movement relative to the driving wheel set 20.

[0072] The position of the limiting member 13 is not limited as long as it can limit the movement of the brush body 10 in the axial direction of the cylinder 11. In some embodiments, limiting members 13 are respectively arranged at both ends of the inner wall 111 of the cylinder 11 along the axial direction of the cylinder 11. In other embodiments, the limiting member 13 is located between both ends of the inner wall 111 of the cylinder 11 along the axial direction of the cylinder 11. For example, please refer to Figure 3 , the limiting member 13 is located at the middle position of the inner wall 111 of the cylinder 11 along the axial direction.

[0073] The limiting member 13 can be integrally formed with the cylinder body 11 and the blade 12, which can facilitate production and manufacturing and increase the structural strength of the brush body 10. The limiting member 13 can also be separately manufactured from the cylinder body 11 and the blade 12. The limiting member 13, the cylinder body 11, and the blade 12 can be made of the same or different materials according to performance requirements. The structural form of the limiting member 13 is not limited. It can be a continuous annular limiting rib or limiting bumps arranged at intervals along the ring.

[0074] In some embodiments, please refer to Figure 3 , the limiting member 13 includes limiting teeth 131 arranged at intervals along the circumference of the inner wall 111 of the cylinder body 11. The form of the limiting teeth 131 is not limited as long as the limiting requirement is met. For example, the cross-sectional shape of the limiting teeth 131 can be trapezoidal, square, triangular, etc. There is a gap between two adjacent limiting teeth 131, and there can be a certain deformation and movement space when the limiting teeth 131 play a limiting role, reducing the possibility of jamming when the cylinder body 11 rotates.

[0075] In some embodiments not shown, the limiting member 13 is formed in a rack shape along the circumference of the inner wall 111 of the cylinder body 11. The rack-shaped limiting member 13 has a rack base body and limiting teeth arranged at intervals on the rack base body. The cross-sectional shape of the limiting teeth can be trapezoidal, square, triangular, etc. The rack base body can improve the overall strength of the brush body 10 and further reduce the possibility of the brush body 10 moving axially. There is a gap between two adjacent limiting teeth, and there can be a certain deformation and movement space when the limiting teeth play a limiting role, reducing the possibility of jamming when the cylinder body 11 rotates.

[0076] In some embodiments, please refer to Figures 6 - 7 , the drive wheel set 20 is used to provide the power for the rotation of the brush body 10. The drive wheel set 20 includes a seat body 23, a coupling shaft 24, and at least one drive wheel 22. The drive wheel 22 is, for example, one, two, or more. The drive wheel 22 includes a support shaft 221, and the cylinder body 11 is sleeved on the support shaft 221. The support shaft 221 can drive the cylinder body 11 to rotate. Seat bodies 23 are respectively arranged at both ends of the support shaft 221, and the support shaft 221 is rotatably connected to the seat bodies 23. The coupling shaft 24 is drivingly connected to one end of the support shaft 221. The coupling shaft 24 is powered by the drive assembly of the cleaning device. The coupling shaft 24 is drivingly connected to the support shaft 221, so that the support shaft 221 drives the cylinder body 11 to rotate, and the blade 12 rotates with the cylinder body 11 to achieve cleaning. When there are two or more drive wheels 22, the drive wheels 22 connected by the coupling shaft 24 are the driving wheels, and the drive wheels 22 not connected to the coupling shaft 24 are the driven wheels.

[0077] Exemplarily, the drive wheel set 20 includes two drive wheels 22. The cylinder body 11 is sleeved on the two drive wheels 22, for example, connected by tooth meshing, that is, teeth capable of meshing are provided on both the inner wall of the cylinder body 11 and the outer wall of the drive wheel 22. By providing two drive wheels 22, the outer peripheral area of the brush body 10 can be increased, the contact area between the brush body 10 and the contact surface can be increased, the number of blades 12 can be increased, and the possibility of hair and other garbage winding around the brush body 10 can be reduced.

[0078] The axial center distance between two adjacent drive wheels 22 is 20 - 50 mm, for example, 20 mm, 30 mm, 40 mm or 50 mm. By reasonably setting the axial center distance between the two drive wheels 22, the number of blades 12 in contact with the surface to be cleaned can be controlled, and different models of roller brush assemblies 100 can be formed to meet different market demands.

[0079] Exemplarily, the seat body 23 is used to mount and fix the drive wheel 22 and the coupling shaft 24 to form an integral small assembly component. When components such as the seat body 23, the drive wheel 22, and the coupling shaft 24 are worn or damaged and need to be replaced, the overall disassembly and assembly can simplify the maintenance process and improve the maintenance efficiency.

[0080] In some embodiments, please refer to Figure 6 , the drive wheel 22 further includes a flexible cylinder 222. The flexible cylinder 222 is sleeved on the support shaft 221, and the cylinder body 11 is sleeved on the flexible cylinder 222. The flexible cylinder 222 can drive the cylinder body 11 to rotate. For example, the flexible cylinder 222 drives the cylinder body 11 to rotate through friction. The support shaft 221 is generally made of a material with relatively high structural strength. For example, the support shaft 221 is made of a metal material. The flexible cylinder 222 is generally made of a soft material and can deform under an external force. During assembly, it can be sleeved on the support shaft 221 through deformation and closely cooperate with the support shaft 221, so that the inner wall of the flexible cylinder 222 fits the outer wall of the support shaft 221. The cylinder body 11 can also be made of a soft material and is sleeved on the flexible cylinder 222 through deformation and closely cooperates with the flexible cylinder 222.

[0081] Exemplarily, the cylinder body 11 and the flexible cylinder 222 can be made of the same material, both using soft materials. For example, the material of the cylinder body 11 can be TPU, and the material of the flexible cylinder 222 can also be TPU.

[0082] In some embodiments, please refer to Figure 6 , there are two drive wheels 22. The drive wheel set 20 further includes a bracket 26. The bracket 26 is located between the two drive wheels 22. The cylinder body 11 is sleeved on the two drive wheels 22 and the bracket 26. The cylinder body 11 is spaced from the bracket 26. Both ends of the bracket 26 are respectively connected to the corresponding seat body 23. The coupling shaft 24 is drivingly connected to one end of the support shaft 221 of one of the drive wheels 22.

[0083] In this embodiment, the seat body 23 can provide an installation position for the bracket 26. The cylindrical body 11 and the bracket 26 are arranged at intervals, and the bracket 26 will not affect the normal operation of the cylindrical body 11. When the cylindrical body 11 is deformed, the bracket 26 can support the cylindrical body 11, increase the contact area between all the blades 12 and the surface to be cleaned, and improve the cleaning effect.

[0084] In some embodiments, please refer to Figure 6 and Figure 7 , the support shaft 221 includes a first step 2211, a second step 2212, a support section 2213 and a limit section 2214. The first step 2211 and the second step 2212 protrude from the support section 2213 and the limit section 2214 respectively along the radial direction of the support shaft 221. The two first steps 2211 are respectively located at both ends of the support shaft 221, the two second steps 2212 are respectively located between the two first steps 2211, the limit section 2214 is located between the two second steps 2212, and the two support sections 2213 are respectively located between the adjacent first step 2211 and the second step 2212. The two flexible cylinders 222 are respectively sleeved on the corresponding support sections 2213, and the first step 2211 and the second step 2212 limit the flexible cylinder 222. The two second steps 2212 are used to limit the brush body 10 along the axial direction of the support shaft 221.

[0085] In this embodiment, the two second steps 2212 protrude from the limit section 2214, and a recessed limit space will be formed at the limit section 2214. The limit member 13 is located in the limit space, and the two second steps 2212 limit the axial movement of the limit member 13, thereby limiting the axial movement of the cylindrical body 11. Prevent the cylindrical body 11 from moving axially and generating a large displacement, which affects the cleaning effect.

[0086] The adjacent first step 2211 and the second step 2212 protrude from the support section 2213, and a recessed limit space will be formed at the support section 2213. The flexible cylinder 222 is located in the limit space, and the first step 2211 and the second step 2212 limit the axial movement of the flexible cylinder 222, thereby limiting the axial movement of the flexible cylinder 222. Prevent the flexible cylinder 222 from moving axially and generating a large displacement, which drives the cylindrical body 11 to move axially and generate a large displacement, affecting the cleaning effect.

[0087] In some embodiments, please refer to Figures 7 - 10 , the drive wheel set 20 further includes a bearing 25, and both ends of the support shaft 221 have a receiving cavity 221a; please refer to Figures 12 - 14, the seat body 23 includes a seat plate 231 and at least one support column 232.

The bearing 25 is sleeved on one end of the support column 232 and is located in the accommodation cavity 221a to be connected to the support shaft 221. At least one support column 232 has a hollow cavity 232a that penetrates axially along the support column 232. The coupling shaft 24 passes through the hollow cavity 232a and the accommodation cavity 221a to be drivingly connected to the support shaft 221.

[0088] In this embodiment, the bearing 25 is used to reduce the friction between the support shaft 221 and the seat body 23, make the rotation of the support shaft 221 smoother, and at the same time can support the support shaft 221, improving the structural strength of the drive wheel set 20. The bearing 25 is located in the accommodation cavity 221a, enabling the support shaft 221 to maintain a stable axial position during rotation, preventing transmission failure caused by the axial movement of the support shaft 221 and affecting the cleaning effect.

[0089] In some embodiments not shown, the bearing 25 may not be used, and the part of the support column 232 of the seat body 23 that cooperates with the support shaft 221 is made of a self-lubricating material, such as copper.

[0090] Exemplarily, please refer to Figure 8 , the coupling shaft 24 includes a spline shaft 241. The surface of the spline shaft 241 has key grooves, and the inner wall of the support shaft 221 has key grooves adapted to the spline shaft 241. By the cooperation of the spline shaft 241 and the support shaft 221 for rotation, the driving stability can be improved. The support column 232 has a hollow cavity 232a. The coupling shaft 24 is powered by the drive assembly of the cleaning device. The coupling shaft 24 passes through the hollow cavity 232a and the accommodation cavity 221a to be drivingly connected to the support shaft 221, thereby enabling the support shaft 221 to drive the cylinder body 11 to rotate, and the blades 12 to move following the cylinder body 11 to achieve cleaning.

[0091] Exemplarily, please refer to Figure 11 , the bracket 26 has a groove 262 corresponding to the position of the limiting section 2214. The groove 262 has two groove walls 2621, and the two groove walls 2621 are used to limit the brush body 10 axially along the support shaft 221. In this way, the two groove walls 2621 and the two second steps 2212 jointly limit the brush body 10 axially along the support shaft 221, which can improve the limiting effect.

[0092] In some embodiments, please refer to Figures 11 - 14 , the drive wheel set 20 further includes a fastener 21 (refer to Figure 6) The seat body 23 has a first mounting hole 23a and a first limiting portion 233, and both ends of the bracket 26 have a second mounting hole 26a and a second limiting portion 261 respectively; the fastener 21 passes through the first mounting hole 23a and the second mounting hole 26a to connect the seat body 23 and the bracket 26; the first limiting portion 233 and the second limiting portion 261 are in limiting connection, wherein one of the first limiting portion 233 and the second limiting portion 261 is a limiting notch, and the other of the first limiting portion 233 and the second limiting portion 261 is a limiting post.

[0093] In this embodiment, by passing the fastener 21 through the first mounting hole 23a and the second mounting hole 26a, the seat body 23 and the bracket 26 can be firmly connected. By inserting the limiting post into the limiting notch, the stability of the connection between the seat body 23 and the bracket 26 can be further improved. And during installation, through the cooperation of the limiting post and the limiting notch, it is convenient to align and the installation speed can be increased. It can be understood that the connection manner between the bracket 26 and the seat body 23 can be only installed by passing the fastener 21 through the first mounting hole 23a and the second mounting hole 26a, or only installed by inserting the limiting post into the limiting notch.

[0094] Exemplarily, the fastener 21 is a bolt, the second mounting hole 26a is a threaded hole, and the fastener 21 passes through the seat body 23 and is threadedly connected to the bracket 26.

[0095] Exemplarily, both sides of the bracket 26 have limiting notches, the seat body 23 has limiting posts corresponding to the limiting notches, the limiting posts are inserted into the limiting notches to align the seat body 23 and the bracket 26, and then the fastener 21 is installed to firmly connect the seat body 23 and the bracket 26.

[0096] The embodiment of the present application also provides a cleaning device 200. Please refer to Figures 15 - 19 , the cleaning device 200 includes a housing 210, a drive assembly 220 and the brush roller assembly 100 according to any one of the embodiments of the present application; the housing 210 has an opening and a receiving space 211c that communicate with each other, the brush roller assembly 100 is installed on the housing 210 and is located in the receiving space 211c, and at least part of the blades 12 protrude from the housing 210 along the opening; the drive assembly 220 is arranged on the housing 210, and the drive assembly 220 is drivingly connected to the drive wheel set 20.

[0097] The cleaning device 200 can be a floor sweeper or a combined sweeping and washing machine, and can be used for cleaning the floors of places such as factories, shopping malls, offices or families, and has a good cleaning effect on garbage such as dust, hair and debris.

[0098] In this embodiment, the blades 12 protrude from the housing 210. During cleaning, after the blades 12 abut against the contact surface, they are deformed, and the end portions fit the contact surface for cleaning, which can improve the cleaning coverage of garbage such as dust, hair and debris, increase the cleaning area and improve the cleaning effect.

[0099] For some examples, see Figures 18 - 19 The shell 210 includes a cover body 211 and a bottom shell 212. The cover body 211 has a mounting groove 211a, and a first opening 211b, a accommodating space 211c and an air suction port 211d that are interconnected. The roller brush assembly 100 is installed on the cover body 211 and is located in the accommodating space 211c. At least part of the seat body 23 is stuck in the mounting groove 211a; the bottom shell 212 has a second opening 212a that is connected to the first opening 211b, and together form an opening of the shell 210. The bottom shell 212 is connected to the cover body 211 and covers the mounting groove 211a. At least part of the blades 12 protrude from the bottom shell 212 along the second opening 212a; the driving assembly 220 is arranged on the cover body 211, and the driving assembly 220 is drivingly connected to the connecting shaft 24.

[0100] In this embodiment, the seat body 23 is partially stuck in the installation groove 211a. When disassembling, the cover body 211 and the bottom shell 212 are detachably connected. First, the bottom shell 212 is removed, and then the seat body 23 is removed from the installation groove 211a, and the entire roller brush assembly 100 can be removed.

[0101] Specifically, the support column 232 of the seat body 23 at one end of the roller brush assembly 100 is released from the corresponding mounting groove 211a, so that the support column 232 at one end is disengaged from the mounting groove 211a, and then the support column 232 of the seat body 23 at the other end is disengaged from the corresponding mounting groove 211a, so that the roller brush assembly 100 can be disassembled as a whole. During installation, the support column 232 of the seat body 23 at one end is first placed in the corresponding mounting groove 211a, and then the support column 232 of the seat body 23 at the other end is placed in the corresponding mounting groove 211a, and the roller brush assembly 100 is installed as a whole, and finally the cover body 211 is fixedly connected to the bottom shell 212.

[0102] In some embodiments, the housing 210 further includes a blocking member 213, and a plurality of blocking members 213 are disposed at intervals on the bottom shell 212, and are located at the front side of the forward direction of the cleaning device 200. Under the support of the blocking member 213, the bottom shell 212 forms a certain angle with the surface to be cleaned, and the closer the blade 12 is to the blocking member 213, the more the blade 12 protrudes from the bottom shell 212.

[0103] In this embodiment, the barrier 213 can isolate some slender objects, such as wires, and reduce the risk of slender objects being drawn into the roller brush assembly 100 and affecting the normal operation of the cleaning device 200. The barrier 213 supports the bottom shell 212 to a certain height, and the blades 12 deform more during the movement from front to rear during the rotation process, which is conducive to drawing garbage between adjacent blades 12. The deformation of the blades 12 continuously pushes the garbage to the air suction port 211d, which can further improve the cleaning effect.

[0104] It can be understood that, in order to improve the cleaning effect, the first blade 121 can protrude from the housing 210 for a longer distance, and the second blade 122 can protrude from the housing 210 for a shorter distance. For example, during the rotation of the second blade 122, it contacts the surface to be cleaned at least at some positions to provide a supporting effect.

[0105] Exemplarily, the cleaning device 200 further includes a control program. After being powered on, the cleaning device 200 can be automatically controlled by the program to operate along the planned route for cleaning, without manual operation of the cleaning device 200, which is convenient and fast to use.

[0106] The embodiment of the present application also provides a cleaning system, including the cleaning device 200 according to any one of the embodiments of the present application. Exemplarily, the cleaning system further includes other devices such as a high-pressure cleaner, a polishing machine or a dehumidifier.
