Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0059] In the present application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0060] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0061] Referring to Figures 1 to 3 As shown, according to the first aspect of the embodiments of the present application, a roller brush assembly is provided, which includes at least two roller brushes for cleaning a surface to be cleaned. Each roller brush includes a connecting end 11 and a free end. The connecting end 11 is driven by a driving device. The free ends of at least two roller brushes are arranged opposite to each other, and a gap is provided between the opposite free ends. By providing at least two roller brushes, compared with a single roller brush, the stability during cleaning is effectively improved. By providing a gap between the opposite free ends, the situation of interference or clamping of sundries between the opposite roller brushes is avoided.

[0062] The roller brush includes a shaft rod and a cleaning member provided on the shaft rod. The cleaning member includes blades 2 and / or tufts of hair 3, or the cleaning member is an integral body formed by connecting the blades 2 and the tufts of hair 3, which can ensure a good cleaning effect.

[0063] Among them, the cleaning member may only include the blades 2, or may only include the tufts of hair 3, or may include both the blades 2 and the tufts of hair 3 at the same time. The blades 2 and the tufts of hair 3 may be a split structure, that is, the blades 2 and the tufts of hair 3 are independent components separated from each other, or may be an integral component formed by connecting the tufts of hair 3.

[0064] The blades 2 are detachably arranged on the shaft rod, which can realize the disassembly and assembly of the blades 2 from the shaft rod, facilitating the replacement of the blades 2. After the blades 2 are damaged, the blades 2 can be directly replaced without replacing the entire roller brush, saving the use cost.

[0065] A plurality of blades 2 are arranged circumferentially along the shaft rod. In the circumferential direction of the shaft rod, the tufts of hair 3 are arranged between adjacent blades 2, which can improve the cleaning effect.

[0066] Among them, a plurality of tufts of hair 3 are arranged between adjacent blades 2, and the plurality of tufts of hair 3 are arranged in a spiral shape along the axial direction of the shaft rod.

[0067] The tuft of hair 3 includes a fixed end and a movable end. The fixed end is connected to the shaft rod, and the movable end extends away from the shaft rod and is inclined towards the free end of the roller brush. When driving the sundries to move, it can play a guiding role for the sundries, so that the sundries can move along the extending direction of the tuft of hair 3 towards the movable end, and then move to the free end of the shaft rod and be sucked into the dust box, further improving the cleaning effect.

[0068] Among them, in the case of no external force causing deformation, the tuft of hair 3 extends in a straight line. The movable end of the tuft of hair 3 extends away from the shaft rod, and the whole is inclined towards the free end of the shaft rod.

[0069] Specifically, in this embodiment, the fixed end of the hair bundle 3 forms an angle of approximately 45° with the outer wall of the shaft.

[0070] In a feasible example, the outer wall of the roller brush can undergo elastic deformation.

[0071] Among them, the outer wall of the roller brush is made of an elastic material, and thus can undergo elastic deformation.

[0072] In a feasible example, the outer wall of the roller brush is rigid.

[0073] It should be noted that rigidity means that, under normal working conditions, the outer wall of the roller brush will not deform or will deform very little, but it does not mean that the outer wall of the roller brush cannot deform at all. Specifically, the outer wall of the roller brush being rigid means that the rigidity of the outer wall is large enough so that, under normal working conditions, the outer wall of the roller brush will not deform.

[0074] Specifically, in this embodiment, the end of the shaft is made of a soft rubber material. The soft rubber has a large surface friction, which is conducive to the ejection of hair.

[0075] It can be understood that the part of the shaft other than the end can be made of a hard rubber material.

[0076] The shaft and the blade 2 are integrally formed, making the roller brush have good structural strength. In the prior art, in the anti-tangle roller brush, the shaft and the blade 2 are usually assembled together. There are usually gaps during assembly. If hair enters at the gap position, the hair cannot detach from the roller brush. In this embodiment, by integrally forming the shaft and the blade 2, the formation of gaps between the shaft and the blade 2 is avoided, thereby preventing hair from entering and enhancing the anti-hair entanglement effect.

[0077] Among them, the shaft and the blade 2 can be integrally formed by double-shot injection molding, in-mold injection molding, liquid injection molding, or hydraulic molding.

[0078] Specifically, in this embodiment, the shaft and the blade 2 are integrally formed by two-color injection molding or in-mold injection molding.

[0079] Among them, the shaft is made of PC or ABS or PA, or the shaft is made of a combination of PC and ABS or a combination of PC and GF or a combination of ABS and GF or a combination of PC, ABS, and GF or a combination of PA and GF;

[0080] Among them, the blade 2 is made of TPU or TPE or silica gel or rubber.

[0081] As the first implementation mode of this embodiment, the roller brush includes a shaft and an end cap 12. The end cap 12 is arranged on the shaft to form the free end of the roller brush, and the end face of the end cap 12 is inclined.

[0082] By providing an end cap 12 and making the end face of the end cap 12 inclined, the end face is thus formed into an inclined surface. When hair winds around the end of the shaft, as the hair gradually tightens, the hair will slide along the inclined end face and finally come off the shaft, solving the problem that the end of the shaft is prone to hair entanglement. Moreover, after the hair detaches from the shaft and rotates with the roller brush, by setting at least one end face of the shaft to be inclined with respect to the central axis of the shaft, the hair is easily thrown out, which is conducive to the hair entering the dust box from the main brush bin, improving the user experience.

[0083] Among them, the end face of the end cap 12 is inclined with respect to the central axis of the shaft.

[0084] Among them, the shaft can be of a cylindrical structure and the shaft extends linearly. The end cap 12 is covered on the free end of the shaft.

[0085] Among them, the end cap 12 is covered on the free end of the shaft.

[0086] Specifically, the end face of the end cap 12 is inclined with respect to the central axis of the shaft, that is, the end face of the end cap 12 is neither parallel nor perpendicular to the central axis of the shaft, which means that the central axis of the shaft forms an angle other than 90 degrees with the end face.

[0087] In one embodiment, the end face inclined with respect to the central axis of the shaft is an arc surface, making the end face smooth so that the hair can slide smoothly on the end face.

[0088] Among them, the arc surface is a convex arc surface, that is, an arc surface protruding outwards, rather than a concave arc surface.

[0089] In one embodiment, the end face inclined with respect to the central axis of the shaft is a flat surface, which can also ensure that the hair slides smoothly on the end face.

[0090] Among them, the end face is a flat surface. When viewed in the radial or axial direction of the shaft, the end face is an inclined flat surface, that is, an inclined plane.

[0091] In one embodiment, the end faces of the end caps 12 oppositely arranged on the roller brush are inclined in the same direction, and the two oppositely arranged roller brushes rotate at the same speed and in the same direction.

[0092] Among them, the end caps 12 oppositely arranged on the roller brush being inclined in the same direction means that the end faces of the two end caps 12 are inclined towards the same direction, making the two end faces substantially parallel.

[0093] In one embodiment, there is a rotational speed difference between the two oppositely arranged roller brushes, further improving the ability to remove hair entanglement.

[0094] Such as Figure 1 、 Figure 4 and Figure 5As shown, in this embodiment, the roller brush assembly includes two roller brushes, namely the first roller brush 5 and the second roller brush 7. The first roller brush 5 and the second roller brush 7 are arranged axially opposite to each other. The end cap 12 of the first roller brush 5 is located at the free end of the shaft of the first roller brush 5, that is, Figure 1 the right end in

[0095] The end cap 12 of the first roller brush 5 and the end cap 12 of the second roller brush 7 are both inclined with respect to the central axis of the shaft, which can enable both the first roller brush 5 and the second roller brush 7 to have good ability to remove hair entanglement and improve the use experience.

[0096] Among them, by making there be a rotational speed difference between the first roller brush 5 and the second roller brush 7, the hair wound on the first roller brush 5 and the second roller brush 7 is more likely to be thrown out and then enter the dust box. Specifically, by setting the rotational speed difference, the first roller brush 5 can pull out the hair wound on the second roller brush 7, or the second roller brush 7 can pull out the hair wound on the first roller brush 5, and then the hair is thrown out and enters the dust box.

[0097] As the second implementation manner of this embodiment, the roller brush assembly further includes a blocking member 8, and at least a part of the blocking member 8 is located between the relatively arranged roller brushes.

[0098] By setting the blocking member 8 and making at least a part of the blocking member 8 be located between the relatively arranged roller brushes, when the hair wound on the roller brush rotates with the roller brush, the hair will be blocked by the hook and then change the moving direction, and the hair turns to move toward the side of the dust collection port 91 and is then sucked into the dust box by the blower, achieving the effect of removing the hair entanglement on the roller brush.

[0099] As Figures 6 to 8 shown, in this second implementation manner, the roller brush assembly includes two roller brushes, namely the first roller brush 5 and the second roller brush 7. The first roller brush 5 and the second roller brush 7 are arranged axially opposite to each other. Specifically, the first roller brush 5 and the second roller brush 7 are coaxially arranged. At least a part of the blocking member 8 is located between the opposite end faces of the first roller brush 5 and the second roller brush 7.

[0100] As Figure 6 and Figure 7 shown, the roller brush assembly includes a roller brush compartment, and the blocking member 8 is arranged on the inner wall of the roller brush compartment, so that the blocking member 8 can be stably connected, and a part of the blocking member 8 can extend between the opposite end faces of the first roller brush 5 and the second roller brush 7.

[0101] The roller brush assembly includes a roller brush compartment. The roller brush compartment is provided with a dust collection port 91 for communicating with the dust box. The blocking member 8 is arranged on the inner wall of the roller brush compartment on the side away from the dust collection port 91 and is arranged opposite to the dust collection port 91, so that the hair blocked by the blocking member 8 can smoothly enter the dust box.

[0102] Among them, the blocking member 8 and the dust collection port 91 are disposed substantially opposite to each other along the radial direction of the roller brush.

[0103] Among them, the dust collection port 91 is an opening through which the main brush chamber communicates with the dust box, that is, the opening closest to the dust box in the main brush chamber. The flow-through area of the dust collection port 91 is smaller than that of the dust inlet. Specifically, dust and sundries are sucked into the main brush chamber through the dust inlet and then enter the dust box through the dust collection port 91.

[0104] As Figure 9 shown, the blocking member 8 includes a connecting section 81 and a blocking section 82. The connecting section 81 is connected to the inner wall of the roller brush chamber, and the blocking section 82 is connected to the connecting section 81. The extending direction of the blocking section 82 is different from that of the connecting section 81.

[0105] By providing the connecting section 81, the blocking member 8 can be stably fixed in the main brush cover 9. By making the extending direction of the blocking section 82 different from that of the connecting section 81, the connecting section 81 can extend between the relatively arranged roller brushes, thereby playing a role in blocking hair.

[0106] Among them, the blocking section 82 extends perpendicularly to the axial direction of the roller brush between the opposing roller brushes.

[0107] As Figure 9 shown, an arc surface for connecting with the inner wall of the main brush cover 9 is provided on the connecting section 81. The arc surface fits along the circumferential direction of the roller brush on the arc-shaped inner wall of the main brush cover 9. The radian of the arc surface of the connecting section 81 is adapted to the radian of the arc-shaped inner wall of the main brush cover 9, thereby achieving a tight fit and connection. Specifically, it can be connected by gluing.

[0108] As Figure 9 shown, the blocking section 82 is connected to the connecting section 81. After the blocking section 82 is connected to the connecting section 81, it generally forms a hook-shaped structure, which can also be called an L-shaped structure. The extending direction of the blocking section 82 is perpendicular to the axial direction of the roller brush and extends between the opposing roller brushes.

[0109] Among them, one end of the blocking section 82 away from the connecting section 81 extends to the central axis of the roller brush.

[0110] The roller brush assembly includes a bracket. The bracket includes a socket rod 41. The roller brush is sleeved on the socket rod 41, so that Gusnai can rotate stably on the socket rod 41.

[0111] The socket rod 41 includes an inner rod and an outer rod. The outer rod is sleeved on the outer peripheral side of the inner rod. A bearing 42 is sleeved on the inner rod and is connected to the inner wall of the outer rod through the bearing 42. By providing the bearing 42 between the outer rod and the inner rod, the relative rotation between the inner rod and the outer rod can be ensured to be more stable, and at the same time, the wear between the outer rod and the inner rod is reduced.

[0112] Among them, the outer rod and the body of the frame are of an integral structure, and one end of the inner rod is rotatably inserted into the outer rod.

[0113] Specifically, one end of the inner rod is connected to the driving component so that the driving component can drive the inner rod to rotate. One section of the inner rod away from the driving component extends out of the outer rod. A rubber core is fixedly sleeved on the section of the inner rod extending out of the outer rod. The shaft rod of the rolling brush is sleeved on the rubber core and the outer rod, and the rubber core and the shaft rod are fixedly connected in the circumferential direction. Thus, the rubber core can drive the shaft rod to rotate, that is, the driving component drives the inner rod to rotate, the inner rod drives the rubber core to rotate, and the rubber core drives the shaft rod to rotate.

[0114] Among them, the inner ring of the bearing 42 is sleeved on the outer peripheral wall of the inner rod, and the outer ring of the bearing 42 is connected to the inner peripheral wall of the outer rod.

[0115] Such as Figures 10 to 13 shown, there are at least two bearings 42, and the at least two bearings 42 are arranged along the axial direction of the inner rod, which can further ensure the stable rotation of the inner rod in the outer rod.

[0116] Specifically, the number of the bearings 42 is two. One bearing 42 is arranged on the inner wall at one end of the outer rod, and the other bearing 42 is arranged on the inner wall at the other end of the outer rod.

[0117] Among them, the bearing 42 is an oil-impregnated bearing 42 or a ball bearing 42, or an oil-impregnated bearing 42 and a ball bearing 42 are provided at the same time, ensuring good rotational stability.

[0118] Specifically, in this embodiment, both of the two bearings 42 are oil-impregnated bearings 42. The oil-impregnated bearing 42 has good wear resistance. The oil-impregnated bearing 42 is made of powder metallurgy material, and the size can be customized into various shapes to meet different design spaces. The sizes of the two bearings 42 are the same, which saves space, simplifies the assembly relationship, and makes the transmission more stable and reliable.

[0119] There are two brackets, and the socket rods 41 of the two brackets are the same or different. In the case where the socket rods 41 of the two brackets are different, anti-fooling can be achieved, avoiding assembly errors and ensuring the product yield.

[0120] The rolling brush is provided with a socket hole and is sleeved on the socket rod 41 through the socket hole. The socket holes of different rolling brushes are the same or different. In the case where the two socket holes are different, anti-fooling can be achieved, avoiding assembly errors and ensuring the product yield..

[0121] Among them, such as Figures 13 to 16 shown, in this embodiment, the rolling brush assembly includes two brackets and two rolling brushes, that is, the first bracket 4 and the second bracket 6, and the first rolling brush 5 and the second rolling brush 7. The first rolling brush 5 is assembled on the first bracket 4, and the second rolling brush 7 is assembled on the second bracket 6.

[0122] Specifically, a first socket hole 51 is provided on the first rolling brush 5, and the first rolling brush 5 is sleeved on the socket rod 41 of the first bracket 4 through the first socket hole 51. The cross-section of the first socket hole 51 is adapted to the cross-section of the socket rod 41 of the first bracket 4. A second socket hole 71 is provided on the second rolling brush 7, and the second rolling brush 7 is sleeved on the socket rod 41 of the second bracket 6 through the second socket hole 71. The cross-section of the second socket hole 71 is adapted to the cross-section of the socket rod 41 of the second bracket 6. The cross-section of the first socket hole 51 is different from the cross-section of the second socket hole 71, and the cross-section of the socket rod 41 of the first bracket 4 is different from the cross-section of the socket rod 41 of the second bracket 6.

[0123] Specifically, as Figure 13 shown, the cross-section of the first socket hole 51 is plum-blossom-shaped, that is, the first socket hole 51 is a plum-blossom-shaped hole. As Figure 14 shown, the cross-section of the socket rod 41 of the first bracket 4 is also plum-blossom-shaped, and the size and shape are adapted to the first socket hole 51. After the socket rod 41 of the first bracket 4 is inserted into the first socket hole 51, the socket rod 41 of the first bracket 4 abuts against the plum-blossom-shaped structure of the first socket hole 51 in the circumferential direction through the plum-blossom structure, thereby driving the first rolling brush 5 to rotate.

[0124] Specifically, as Figure 15 shown, the cross-section of the second socket hole 71 is rectangular, that is, the second socket hole 71 is a rectangular hole. As Figure 16 shown, the cross-section of the socket rod 41 of the second bracket 6 is also rectangular, and the size and shape are adapted to the second socket hole 71. After the socket rod 41 of the second bracket 6 is inserted into the second socket hole 71, the socket rod 41 of the second bracket 6 abuts against the rectangular structure of the second socket hole 71 in the circumferential direction through the rectangular structure, thereby driving the second rolling brush 7 to rotate. The cross-section of the first socket hole 51 and the cross-section of the socket rod 41 of the first bracket 4 are plum-blossom-shaped, and the cross-section of the second socket hole 71 and the cross-section of the socket rod 41 of the second bracket are rectangular. The cross-sectional shapes are different and the sizes are different, so that the socket rod 41 of the first bracket 4 cannot be inserted into the second socket hole 71, and the socket rod 41 of the second bracket 6 cannot be inserted into the first socket hole 51 either, thereby forming an anti-mistake function.

[0125] As Figures 17 to 19 shown, as the third implementation manner of this embodiment, the free ends of at least two rolling brushes are inclined towards the dust collection port 91, which can make the dust more easily be driven by the rolling brushes into the dust collection port 91, and then more easily be sucked into the dust box, improving the cleaning effect.

[0126] Among them, the opposite ends of two opposite rolling brushes, that is, the free ends of the two rolling brushes, are inclined towards the dust collection port 91.

[0127] Among them, the rotary brush is generally in a cylindrical structure and extends linearly along its own central axis.

[0128] Among them, the internal space of the main brush cover 9 is connected to the dust box through the dust collection port 91. The flow-through area of the dust collection port 91 is relatively small, so the wind speed is relatively fast. By setting the free end of the rotary brush to extend towards the dust collection port 91, the rotary brush can drive dust to the dust collection port 91 through rotation, and thus it is more easily sucked into the dust box.

[0129] Among them, the dust collection port 91 is arranged at the middle position of the main brush cover 9 along the transverse direction. The connecting end 11 of the rotary brush is located at one end of the main brush cover 9, and the free end of the rotary brush extends towards the dust collection port 91 at the middle of the main brush cover 9.

[0130] Specifically, the first rotary brush 5 is located on the first side of the dust collection port 91, and the second rotary brush 7 is located on the second side of the dust collection port 91. The free end of the first rotary brush 5 is inclined towards the dust collection port 91, and the free end of the second rotary brush 7 is inclined towards the dust collection port 91, so that the first rotary brush 5 and the second rotary brush 7 are arranged at an angle, and dust can be synchronously driven to move to the dust collection port 91 from two directions, further improving the cleaning effect.

[0131] Among them, the first rotary brush 5 and the second rotary brush 7 are arranged in a substantially left-right symmetric manner.

[0132] Among them, the first side and the second side are respectively the left and right sides of the dust collection port 91. It can be understood that the first side is the left side of the dust collection port 91, and the second side is the right side of the dust collection port 91.

[0133] Among them, the free end of the first rotary brush 5 and the free end of the second rotary brush 7 are opposite ends in the left-right direction.

[0134] One end of the bracket is connected to the driving device, and the other end is inclined towards the dust collection port 91.

[0135] Among them, the rotary brush can rotate on the bracket with its own central axis as the rotation center.

[0136] Specifically, the first rotary brush 5 is rotatably arranged on the first bracket 4, and the second rotary brush 7 is rotatably arranged on the second bracket 6. One end of the first bracket 4 and the second bracket 6 is connected to the driving device, and the other end is inclined towards the dust collection port 91, so that the first rotary brush 5 can rotate on the first bracket 4 with its own central axis as the rotation center, and the second rotary brush 7 can rotate on the second bracket 6 with its own central axis as the rotation center, ensuring good rotational stability of the first rotary brush 5 and the second rotary brush 7.

[0137] Among them, the first rolling brush 5 is rotatably sleeved on the socket rod 41 of the first bracket 4. The first rolling brush 5, the socket rod 41 of the first bracket 4, and the driving member of the driving device directly connected to the socket rod 41 are coaxially arranged, and the axis extends towards the dust collection port 91. That is, the socket rod 41 of the first bracket 4 is inclined with respect to the side wall of the brush cover.

[0138] Among them, the second rolling brush 7 is rotatably sleeved on the socket rod 41 of the second bracket 6. The second rolling brush 7, the socket rod 41 of the second bracket 6, and the driving member of the driving device directly connected to the socket rod 41 are coaxially arranged, and the axis extends towards the dust collection port 91. That is, the socket rod 41 of the second bracket 6 is inclined with respect to the side wall of the brush cover.

[0139] A dust inlet is provided on the main brush cover 9, and the opening angle of the dust inlet is adapted to the angle formed by the two rolling brushes.

[0140] Among them, the two rolling brushes with opposite free ends form an obtuse angle, that is, the angle formed by the first rolling brush 5 and the second rolling brush 7 is an obtuse angle. The dust inlet corresponds to an obtuse angle structure.

[0141] In the second aspect of this embodiment, an automatic cleaning device is provided, including the rolling brush assembly as described above.

[0142] In the third aspect of this embodiment, a cleaning system is provided, including the rolling brush assembly as described above or the automatic cleaning device as described above.
