Description

Technical Field

[0001] This application relates to a cleaning component and a sweeping robot, belonging to the field of cleaning equipment technology. Background Technology

[0002] When cleaning the floor, a robotic vacuum cleaner primarily uses a rotating brush to contact the ground, combined with suction power to collect dirt and grime into its interior. Consequently, the suction power of the robotic vacuum cleaner determines its effectiveness in collecting dirt and grime.

[0003] Because the roller brush can partially block the air intake inside the robot vacuum, it makes it difficult for the robot vacuum to increase its suction power, resulting in a poorer cleaning effect. Utility Model Content

[0004] This application provides a cleaning component and a robotic vacuum cleaner to solve the problem of insufficient suction power in robotic vacuum cleaners in the related art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a cleaning component, comprising:

[0007] The housing has an air inlet, a mounting cavity, and a dust collection port, wherein the mounting cavity is connected to both the air inlet and the dust collection port;

[0008] Two roller brushes, at least a portion of each roller brush is disposed in the mounting cavity, and both roller brushes are rotatably connected to the housing. The central axes of the two roller brushes intersect or are collinear, and both roller brushes are disposed opposite to the dust collection port.

[0009] The outer diameter of the portion of the roller brush adjacent to the air inlet is smaller than the outer diameter of the portion of the roller brush away from the air inlet;

[0010] A drive unit, connected to the roller brush, is configured to drive the roller brush to rotate.

[0011] In the cleaning assembly proposed in this application, the roller brush can contact the ground, and the drive unit can drive the roller brush to rotate, allowing the roller brush to roll up debris from the ground into the mounting cavity. The air inlet of the housing can be connected to the dust box, and a negative pressure is formed inside the dust box, which can suck debris from the mounting cavity and the surface of the roller brush into the dust box through the air inlet. By making the outer diameter of the portion of the roller brush near the air inlet smaller than the outer diameter of the portion of the roller brush away from the air inlet, the outer diameter of some parts of the roller brush can be relatively small, while the outer diameter of others can be relatively large. The smaller outer diameter of the portion of the roller brush near the air inlet means that the roller brush occupies less space in the mounting cavity near the air inlet, which reduces the obstruction of the air inlet by the roller brush, resulting in stronger suction at the air inlet, and allowing the cleaning assembly to more fully suck up debris. The relatively larger outer diameter of the portion of the roller brush away from the air inlet allows the roller brush to maintain a relatively large surface area, so that the roller brush still has a better cleaning effect on the ground debris, ultimately resulting in a better cleaning effect of the cleaning assembly of this application.

[0012] In some embodiments, the roller brush has a first side and a second side in the axial direction of the roller brush, the direction from the first side to the second side being the direction in which the roller brush is away from the air inlet, and the outer diameter of the roller brush gradually increases in the direction from the first side to the second side.

[0013] This allows the roller brush to have a frustum or cone structure, making the roller brush structure more regular and easier to process.

[0014] In some embodiments, the central axes of the two rollers are arranged to intersect.

[0015] In some embodiments, the half-apex angle of the cone on which the roller brush is located is a first angle, and the angle between the axial direction of the roller brush and the plane on which the dust collection port is located is a second angle. The first angle and the second angle are equal, so that in the direction from the first side to the second side, the distance between the outer wall of the roller brush facing the dust collection port and the dust collection port is consistent.

[0016] By ensuring that the spacing of the roller brushes facing the air inlet is consistent, the roller brushes can make contact with the ground along the circumferential outer wall from the first side to the second side, increasing the contact area between the roller brushes and the ground and improving the cleaning effect.

[0017] In some implementations, the first angle is greater than 0° and not greater than 8°.

[0018] In some implementations, the first angle is 4°.

[0019] By setting the first angle to be greater than 0° and not greater than 8°, and specifically to 4°, the outer diameter of the first side and the outer diameter of the second side of the roller brush are not too large, making it easier for the roller brush to be installed in the mounting cavity of the housing.

[0020] In some embodiments, the first sides of the two rollers are positioned opposite each other and spaced apart.

[0021] The spacing between the first sides of the two roller brushes allows hair wrapped around the roller brush to detach from the first side, preventing hair from accumulating on the roller brush.

[0022] In some embodiments, the housing has a limiting wall facing the sidewall of the roller brush, and the limiting wall is spaced at the same distance from the sidewall of the roller brush along the direction from the first side to the second side.

[0023] Setting a limiting wall can make the structure of the shell more compact.

[0024] In some embodiments, the roller brush includes a roller, a bristle brush, and a rubber brush. The bristle brush and the rubber brush are both disposed on the side wall of the roller. Along the direction from the first side to the second side, the height of the bristle brush is the same, the height of the rubber brush is the same, and the height of the bristle brush is greater than the height of the rubber brush.

[0025] By ensuring the brush bristles are at the same height from the first to the second side, all parts of the brush along the first to the second side can make full contact with the ground. Similarly, by ensuring the adhesive brush is at the same height from the first to the second side, all parts of the adhesive brush along the first to the second side can make full contact with the ground.

[0026] In some embodiments, the drive includes a driver, a first gear, and a second gear. The first gear is connected to the driver, the second gear meshes with the first gear, and the second gear is connected to the roller brush. The axial angle between the axial direction of the second gear and the axial direction of the first gear is a third angle, and the first angle and the third angle are equal.

[0027] By making the third angle equal to the first angle, the distance between the side of the roller brush facing the dust collection port and the plane where the dust collection port is located can be made consistent.

[0028] Secondly, based on the cleaning components described above, this application also provides a robotic vacuum cleaner that includes the cleaning components described above.

[0029] The robotic vacuum cleaner provided in this application includes the aforementioned cleaning components, which makes the robotic vacuum cleaner have greater suction power and better cleaning effect. Attached Figure Description

[0043] 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. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] When cleaning the floor, a robotic vacuum cleaner primarily uses a rotating brush to contact the ground, combined with suction power to collect dirt and grime into its interior. Consequently, the suction power of the robotic vacuum cleaner determines its effectiveness in collecting dirt and grime.

[0045] Because the roller brush can partially block the air intake inside the robot vacuum, it makes it difficult for the robot vacuum to increase its suction power, resulting in a poorer cleaning effect.

[0046] In the cleaning assembly proposed in this application, the roller brush can contact the ground, and the drive unit can drive the roller brush to rotate, allowing the roller brush to roll up debris from the ground into the mounting cavity. The air inlet of the housing can be connected to the dust box, and a negative pressure is formed inside the dust box, which can suck debris from the mounting cavity and the surface of the roller brush into the dust box through the air inlet. By making the outer diameter of the portion of the roller brush near the air inlet smaller than the outer diameter of the portion of the roller brush away from the air inlet, the outer diameter of some parts of the roller brush can be relatively small, while the outer diameter of others can be relatively large. The smaller outer diameter of the portion of the roller brush near the air inlet means that the roller brush occupies less space in the mounting cavity near the air inlet, which reduces the obstruction effect of the roller brush on the air inlet, resulting in stronger suction at the air inlet, and the cleaning assembly can more fully suck up debris. The relatively larger outer diameter of the portion of the roller brush away from the air inlet allows the roller brush to maintain a relatively large surface area, so that the roller brush still has a better cleaning effect on the ground debris, ultimately making the cleaning assembly of this application have a better cleaning effect.

[0047] The robotic vacuum cleaner proposed in this application includes the aforementioned cleaning components, which makes the robotic vacuum cleaner have greater suction power and better cleaning effect.

[0048] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0049] This application proposes a cleaning component, with reference to... Figure 1 As shown, it includes a housing 100, two roller brushes 200, and a drive unit 300. This cleaning assembly can be used in a robotic vacuum cleaner.

[0050] The housing 100 is the basic component of the cleaning assembly of this application. The housing 100 provides a mounting base for at least some other components of the cleaning assembly and serves to protect those components. The housing 100 can be made of metal, giving it better structural strength, thus improving its durability and reliability. The housing 100 can also be made of polymer material, allowing it to maintain a certain structural strength while remaining relatively lightweight. Furthermore, the housing 100 can also employ a structure combining some metal and some polymer materials. Specifically, parts of the housing 100 that are easily subjected to external impact or damage can be made of metal, while other parts can be made of polymer materials. This allows the housing 100 to achieve good structural strength without becoming excessively heavy.

[0051] refer to Figures 1 to 3 As shown, the housing 100 has a mounting cavity 120, which is a hollow structure within the housing 100. The housing 100 also has an air inlet 110 and a dust collection port 130, which are openings on the surface of the housing 100 and are both connected to the mounting cavity 120. When the cleaning component of this application is applied to a robotic vacuum cleaner, the air inlet 110 can be connected to the dustbin of the robotic vacuum cleaner, allowing the internal cavity of the dustbin to communicate with the mounting cavity 120 through the air inlet 110. The mounting cavity 120 can communicate with the outside of the housing 100 through the dust collection port 130, creating a negative pressure inside the dustbin. The dust collection port 130 can be positioned opposite the ground, allowing external debris to be sucked into the mounting cavity 120 through the dust collection port 130 and then sucked into the dustbin through the air inlet 110.

[0052] At least a portion of each of the two roller brushes 200 is disposed within the mounting cavity 120, and both roller brushes 200 are rotatably connected to the housing 100. A drive unit 300 is connected to the roller brushes 200 and configured to drive the roller brushes 200 to rotate. Both roller brushes 200 are positioned opposite the dust collection port 130. Specifically, both roller brushes 200 can be entirely located within the mounting cavity 120 of the housing 100, and a portion of the circumferential sidewall of the roller brushes 200 can be positioned precisely at the dust collection port 130. Thus, when the cleaning assembly is placed on the ground and the dust collection port 130 is opposite the ground, the roller brushes 200 can contact the ground. When the roller brushes 200 rotate, they can draw debris from the ground into the mounting cavity 120 and suck it into the dust box through the air inlet 110, thereby achieving the purpose of cleaning the ground.

[0053] refer to Figure 4As shown, the central axes of the two roller brushes 200 intersect or are collinear. When the central axes of the two roller brushes 200 are collinear, the length directions of the two roller brushes 200 are consistent, allowing the two roller brushes 200 to be arranged side by side. This allows the two roller brushes 200 to clean a larger area of ​​the floor in a single movement along the direction of travel of the cleaning component, thereby making the cleaning component of this application more efficient at cleaning floor debris.

[0054] refer to Figure 4 As shown, the central axis of the roller brush 200 is... Figure 4 M in the middle is composed of Figure 4 As can be seen, the central axes M of the two roller brushes 200 intersect and form an intersection point. When the central axes of the two roller brushes 200 intersect, and the cleaning component moves on the ground, the two roller brushes 200 can cover a larger ground area. Thus, along the direction of travel of the cleaning component, the two roller brushes 200 enable the cleaning component to clean a larger area of ​​the ground in a single movement, thereby making the cleaning component of this application more efficient at cleaning ground debris.

[0055] refer to Figures 2 to 3 As shown, the outer diameter of the portion of the roller brush 200 adjacent to the air inlet 110 is smaller than the outer diameter of the portion of the roller brush 200 away from the air inlet 110. This allows for a relatively small outer diameter in one part of the roller brush 200 and a relatively large outer diameter in another part. The smaller outer diameter of the portion of the roller brush 200 adjacent to the air inlet 110 reduces the space occupied by the roller brush 200 within the mounting cavity 120, thus reducing the obstruction effect of the roller brush 200 on the air inlet 110 and resulting in stronger suction at the air inlet 110, allowing the cleaning components to more effectively suck up debris. The relatively larger outer diameter of the portion of the roller brush 200 away from the air inlet 110 allows the roller brush 200 to maintain a relatively large surface area. This results in a larger contact area between the roller brush 200 and the ground, ensuring a good cleaning effect for ground debris.

[0056] Therefore, in the cleaning assembly proposed in this application, the roller brush 200 can contact the ground, and the drive unit 300 drives the roller brush 200 to rotate. The roller brush 200 can roll up the debris on the ground into the mounting cavity 120, and the debris can be sucked into the dust box through the air inlet 110. The outer diameter of the part of the roller brush 200 adjacent to the air inlet 110 is relatively small, while the outer diameter of the part of the roller brush 200 directly from the air inlet 110 is relatively large. This makes the space occupied by the roller brush 200 in the mounting cavity 120 adjacent to the air inlet 110 smaller, which can reduce the obstruction effect of the roller brush 200 on the air inlet 110, resulting in greater suction at the air inlet 110. The cleaning assembly can more fully suck up the debris, resulting in a better cleaning effect.

[0057] In some implementations, reference Figure 4As shown, the roller brush 200 of this application has a first side 211 and a second side 212 in its axial direction. The first side 211 and the second side 212 of the roller brush 200 are its two ends in its axial direction. The direction from the first side 211 to the second side 212 of the roller brush 200 is the direction of the roller brush 200 away from the air inlet 110 of the housing 100. Accordingly, the first side 211 of the roller brush 200 is the portion of the roller brush 200 adjacent to the air inlet 110 of the housing 100, and the second side 212 of the roller brush 200 is the portion of the roller brush 200 away from the air inlet 110 of the housing 100. In the direction from the first side 211 to the second side 212 of the roller brush 200, the outer diameter of the roller brush 200 gradually increases, so that the outer diameter of the first side 211 of the roller brush 200 is smaller than the outer diameter of the second side 212 of the roller brush 200. The outer diameter of the part of the roller brush 200 located between the first side 211 and the second side 212 is larger than the outer diameter of the first side 211 and smaller than the outer diameter of the second side 212. The roller brush 200 as a whole can be in the form of a conical structure or a frustum structure.

[0058] For details, please refer to Figure 5 As shown, the roller brush 200 has a first end face 213 adjacent to the first side 211 and a second end face 214 adjacent to the second side 212. The first end face 213 and the second end face 214 are the two axial end faces of the roller brush 200. The first end face 213 forms a projection area on the second end face 214 in the axial direction of the roller brush 200. The center of the projection area coincides with the center of the second end face 214. Correspondingly, the line connecting the center of the first end face 213 and the center of the second end face 214 is the central axis M of the roller brush 200. This makes the structure of the roller brush 200 more regular, making the manufacturing and processing of the roller brush 200 simpler and reducing the manufacturing process difficulty of the cleaning component of this application.

[0059] It should be understood that, since the first side 211 of both roller brushes 200 is close to the air inlet of the housing 100, the first side 211 of the two roller brushes 200 is positioned close to each other, and the second side 212 of the two roller brushes 200 is positioned far apart from each other.

[0060] In some implementations, reference Figure 4 As shown, the central axes M of the two roller brushes 200 in this application can be arranged to intersect. By arranging the central axes M of the two roller brushes 200 to intersect, the two roller brushes 200 can be arranged at an angle, which can avoid the overall length of the combined structure of the two roller brushes 200 being too large, so that the size of the cleaning component in this application is not too large in a single direction, and the structure can be more compact.

[0061] In some implementations, reference Figure 5 As shown, the roller brush 200 of this application has a frustum structure, and the semi-apex angle of the cone containing the roller brush 200 is the first angle. Wherein, Figure 5The solid lines in the image show the cross-sectional structure of the roller brush 200 in the direction passing through the central axis of the roller brush 200. Figure 5 The dashed line M in the diagram represents the centerline of the 200mm roller brush. Figure 5 The dashed line L in the diagram represents the portion of the cone adjacent to the apex of the cone containing the roller brush 200. Correspondingly, Figure 5 In this context, angle α is the half-apex angle of the cone containing the roller brush 200, i.e., the first angle.

[0062] The angle between the axial direction of the roller brush 200 and the plane containing the dust collection port 130 of the housing 100 is the second angle. When the housing 100 is placed on a horizontal plane and the dust collection port 130 is opposite to the horizontal plane, the plane containing the dust collection port 130 is parallel to the horizontal plane. Figure 5 The dashed line K is parallel to the horizontal plane and also parallel to the plane where the dust collection port 130 is located. The second angle is... Figure 5 The first angle and the second angle are equal, ensuring that the distance between the outer wall of the roller brush 200 facing the dust collection port 130 of the housing 100 and the dust collection port 130 is consistent along the direction from the first side 211 to the second side 212. Correspondingly, the distance between the side of the roller brush 200 facing the dust collection port 130 and the ground can be kept consistent along the direction from the first side 211 to the second side 212. This allows the cleaning assembly to make full contact with the ground along each part of its sidewall in the direction from the first side 211 to the second side 212 when it travels along the ground, thus fully entraining the debris into the mounting cavity 120 and ultimately sucking it into the dust box connected to the air inlet 110. Therefore, the cleaning assembly of this application achieves a more thorough cleaning effect on the ground debris during its movement.

[0063] In some embodiments, the first angle in this application can be set to be greater than 0° and not greater than 8°. If the first angle is 0°, the second angle will also be 0°, preventing the roller brush 200 from forming a frustum structure. If the first angle is greater than 8°, it will be too large, resulting in an excessively large outer diameter of the second side 212 of the roller brush 200, and consequently, an excessively large overall outer diameter of the roller brush 200. This makes it difficult to install the roller brush 200 within the mounting cavity 120 of the housing 100.

[0064] Therefore, by making the first angle greater than 0° and not greater than 8°, the outer diameters of the first side 211 and the second side 212 of the roller brush 200 will not be too large, thereby making the overall structure of the roller brush 200 more compact, and the roller brush 200 can be conveniently installed in the mounting cavity 120 of the housing 100.

[0065] In some embodiments, the first angle of this application is 4°. By setting the first angle to 4°, the outer diameter of the first side 211 and the outer diameter of the second side 212 of the roller brush 200 can be moderate, thereby making the overall outer diameter of the roller brush 200 moderate. In this way, the roller brush 200 has a compact and reasonable structure, and the roller brush 200 has sufficient contact with the ground, making the roller brush 200 more effective at cleaning up ground debris.

[0066] In some implementations, reference Figure 4 As shown, the first sides 211 of the two roller brushes 200 of this application are arranged opposite each other, and the first sides 211 of the two roller brushes 200 are spaced apart. By arranging the first sides 211 of the two roller brushes 200 opposite each other, the first sides 211 of the two roller brushes 200 can be at the same height, and the distance between the side of the two roller brushes 200 facing the dust collection port 130 and the ground can be consistent. Accordingly, the structures of the two roller brushes 200 can be set to be identical, and the difference between the two roller brushes 200 is in the installation position. This can reduce the number of components in the cleaning assembly of this application and reduce the manufacturing cost of the cleaning assembly.

[0067] The first sides 211 of the two roller brushes 200 are spaced apart, so that there is a gap between the first sides 211 of the two roller brushes 200. Correspondingly, the first sides 211 of the two roller brushes 200 are not connected to the housing 100, and the second sides 212 of the two roller brushes 200 are rotatably connected to the housing 100, so that both roller brushes 200 are rotatably connected to the housing 100.

[0068] Because there is a gap between the first sides 211 of the two roller brushes 200, and the outer diameter of the second side 212 of the roller brush 200 gradually decreases from the first side 211, when hair or debris gets tangled in the roller brush 200, as the roller brush 200 continues to rotate, the hair can move along the direction from the second side 212 to the first side 211 until it is detached from the first side 211 of the roller brush 200. This allows the hair to be directly sucked into the dustbin through the air inlet 110, preventing it from getting tangled in the roller brush 200 and failing to detach automatically. This makes cleaning the roller brush 200 more convenient and ultimately makes the cleaning component and the robot vacuum cleaner of this application easier to use.

[0069] The air inlet of the housing 100 can be located in the middle part of the housing 100, and the first side 211 of the roller brush 200 can be arranged opposite to the air inlet of the housing 100. In this way, after the hair and debris leave the roller brush 200 through the first side 211, they can be sucked into the dust box more efficiently through the air inlet 110.

[0070] In some implementations, reference Figure 6As shown, to further compact the structure of the cleaning component of this application, the housing 100 may also be provided with a limiting wall 140 having a sidewall facing the roller brush 200. Specifically, the limiting wall 140 is the inner wall of the mounting cavity 120 of the housing 100. Along the direction from the first side 211 to the second side 212 of the roller brush 200, the distance between the limiting wall 140 of the housing 100 and the sidewall of the roller brush 200 remains consistent. Correspondingly, the limiting wall 140 of the housing 100 is also an inclined structural surface. Thus, along the direction from the first side 211 to the second side 212 of the roller brush 200, the surface of the housing 100 can form a structure recessed towards the mounting cavity 120 of the housing 100, thereby making the structure of the housing 100 more compact, occupying less space, and making the structure of the cleaning component and the sweeping robot more compact.

[0071] When the roller brush 200 is installed in the mounting cavity 120 of the housing 100, the limiting wall 140 can also limit the roller brush 200 and position the roller brush 200, thus making the installation of the roller brush 200 more convenient.

[0072] In addition, the limiting wall 140 can also compress the space of the mounting cavity 120 to a certain extent. Correspondingly, the negative pressure effect in the mounting cavity 120 is more obvious, which can make the garbage on the ground more efficiently sucked into the air inlet 110 from the mounting cavity 120 and finally sucked into the dust box.

[0073] It should be understood that there are two roller brushes 200 in this application, and correspondingly, there are also two limiting walls 140, so that the outer wall of the housing 100 has a structure indented from both sides to the middle.

[0074] In some implementations, reference Figure 7 As shown, the roller brush 200 of this application may include a roller 210, a brush 220, and a rubber brush 230. Both the brush 220 and the rubber brush 230 are disposed on the side wall of the roller 210. Along the direction from the first side 211 to the second side 212 of the housing 100, the heights of the brush 220 and the rubber brush 230 are consistent. By ensuring that the brushes 220 are at a consistent height, when the brush 220 is facing the ground, all parts of the brush 220 in the direction from the first side 211 to the second side 212 can contact the ground, ensuring sufficient contact between the brush 220 and the ground. When the brush 220 rotates with the roller 210, it can entrain dust, debris, and some particulate matter from the ground, bringing them into the mounting cavity 120 where they are sucked into the dust box.

[0075] By ensuring that the height of the adhesive brush 230 is uniform, when the adhesive brush 230 is facing the ground, all parts of the adhesive brush 230 in the direction from the first side 211 to the second side 212 can contact the ground, thus ensuring that the adhesive brush 230 can make full contact with the ground.

[0076] The height of the brush 220 is greater than that of the rubber brush 230, allowing the brush 220 to make more full contact with the ground, thus making the brush 220 more effective at cleaning up ground debris.

[0077] In some implementations, reference Figure 4 and Figure 8 As shown, in order for the drive unit 300 of this application to drive the roller brush 200 to rotate, the drive unit 300 may be provided with a driver 310, a first gear 320, and a second gear 330. The driver 310 may be disposed on the housing 100, allowing for fixed installation. The driver 310 may be a motor. The first gear 320 is connected to the output shaft of the driver 310, and the driver 310 can drive the first gear 320 to rotate. The second gear 330 meshes with the first gear 320 and is connected to the roller brush 200. Thus, the driver 310 driving the first gear 320 to rotate can drive the second gear 330 to rotate, ultimately driving the roller brush 200 to rotate.

[0078] The angle between the axis of the first gear 320 and the axis of the second gear 330 is a third angle, wherein the axis of the first gear 320 is... Figure 8 In the diagram, S represents the axis of the second gear 330. Figure 8 In the T, the third angle is equal to the first angle, so that the roller brush 200 connected to the second gear 330 can be tilted. Correspondingly, along the direction from the first side 211 to the second side 212 of the roller brush 200, the distance between the outer wall of the dust collection port 130 of the housing 100 and the dust collection port 130 can be kept consistent.

[0079] Specifically, the axis of the first gear 320 can be parallel to the plane where the dust collection port 130 of the housing 100 is located, and the axis of the second gear 330 is collinear with the central axis of the roller brush 200, so that the roller brush 200 can be tilted when it is located in the mounting cavity 120 of the housing 100.

[0080] In addition, the drive unit 300 of this application can be provided with more gears, and the number of teeth of the first gear 320 and the number of teeth of the second gear 330 can be set according to actual needs. This allows the drive unit 300 to also have the function of a speed reduction mechanism, so as to better control the rotation of the roller brush 200.

[0081] In some implementations, reference Figure 4As shown, it should be understood that since the number of roller brushes 200 in this application is two, the number of first gears 320 and second gears 330 is also two, and the drive unit 300 may also include a transmission rod 340. The two first gears 320 mesh with the two second gears 330 respectively, and the two second gears 330 are respectively connected to the two roller brushes 200. One of the first gears 320 is connected to the driver 310, and the transmission rod 340 can be connected to both first gears 320. Thus, after the driver 310 drives one first gear 320 to rotate, it can drive the other first gear 320 to rotate via the transmission rod 340, thereby enabling the two roller brushes 200 to rotate synchronously. This reduces the number of drivers 310; only one driver 310 can drive the two roller brushes 200 to rotate synchronously, reducing the number of components in the cleaning assembly of this application and lowering the cost of the cleaning assembly.

[0082] Based on the cleaning components described above, this application also proposes a sweeping robot, which includes the cleaning components described above. The sweeping robot may also be equipped with a dust box and a moving component. The dust box is connected to the air inlet of the housing, and the moving component is disposed in the housing. The moving component can drive the housing to move, thereby making the sweeping robot as a whole movable.
