[0112] In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure.

[0113] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0114] In this disclosure, unless specifically defined and limited otherwise, the terms "mounting", "connected", "connection", "fixed", and the like, should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in this disclosure can be understood according to the specific circumstances.

[0115] The preferred embodiments of the present disclosure are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the disclosure.

[0116] The existing sweeping machine usually only has one roller brush, and the stability during cleaning operation is poor.

[0117] The current cleaning equipment, such as a sweeping machine, a sweeping and mopping all-in-one machine, etc., usually, the roller brush is close to the ground to clean dust, particulate matter, and hair, etc. on the ground. However, when the roller brush rotates to clean, the hair and other filamentary substances are easily wound on the roller brush and cannot be sucked into the air duct together with the dust, which not only affects the dust suction effect, but also increases the wear of the roller brush driving part, reduces the service life of the cleaning equipment, and requires manual cleaning of the hair on the roller brush, which affects the user's experience. In addition, for the cantilever type roller brush, since the end part usually needs to extend the blade in the axial direction, the root of the roller brush is often wound with hair, and even wound on the roller brush driving shaft, which increases the wear of the roller brush driving part, reduces the service life of the cleaning equipment, and affects the use experience.

[0118] In combination with FIGS. 1-3, according to an embodiment of the present disclosure, a roller brush assembly is provided, which includes at least two roller brushes, each roller brush including a connecting end 11 and a free end, the connecting end 11 being driven by a driving device, the free ends of the at least two roller brushes being oppositely arranged, and a gap being arranged between the oppositely arranged free ends. By arranging at least two roller brushes, the stability during cleaning is effectively improved compared with one roller brush. By arranging a gap between the oppositely arranged free ends, the interference or jamming of the oppositely arranged roller brushes by sundries is avoided.

[0119] The roller brush includes a shaft and a cleaning element arranged on the shaft. The cleaning element includes a blade 2 and / or a first bundle of hairs 3, or the cleaning element is integrated with the blade 2 and the first bundle of hairs 3, which can ensure good cleaning effect.

[0120] The cleaning element can only include the blade 2, or only include the first bundle of hairs 3, or include both the blade 2 and the first bundle of hairs 3. The blade 2 and the first bundle of hairs 3 can be a split structure, that is, the blade 2 and the first bundle of hairs 3 are independent components separated from each other, or can be a combined component integrated with the first bundle of hairs 3.

[0121] The blade 2 is detachably arranged on the shaft, which can realize the disassembly of the blade 2 from the shaft, facilitate the replacement of the blade 2, and directly replace the blade 2 after the blade 2 is damaged, without replacing the entire roller brush, thereby saving the use cost.

[0122] The plurality of blades 2 are arranged in the circumferential direction of the shaft, and the first hair bundle 3 is arranged between the adjacent blades 2 in the circumferential direction of the shaft, which can improve the cleaning effect.

[0123] The plurality of first hair bundles 3 are arranged in a spiral shape along the axial direction of the shaft.

[0124] The first hair bundle 3 includes a fixed end and a movable end, the fixed end is connected with the shaft, and the movable end extends away from the shaft and is inclined toward the free end of the roller brush, which can guide the dirt when the dirt is moved, so that the dirt can move along the extension direction of the first hair bundle 3 to the movable end, and then move to the free end of the shaft and be sucked into the dust box, thereby further improving the cleaning effect.

[0125] In the case of not being deformed by external force, the first hair bundle 3 extends in a straight line, the movable end of the first hair bundle 3 extends away from the shaft, and the whole is inclined toward the free end of the shaft.

[0126] Specifically, in the embodiment, the fixed end of the first hair bundle 3 is substantially at an angle of 45° with the outer wall of the shaft.

[0127] In a feasible example, the outer wall of the roller brush can be elastically deformed.

[0128] The outer wall of the roller brush is made of an elastic material, thereby being capable of being elastically deformed.

[0129] In a feasible example, the outer wall of the roller brush is rigid.

[0130] It should be noted that the rigidity means that the outer wall of the roller brush will not be deformed or will be slightly deformed in the normal working state, but it does not mean that the outer wall of the roller brush cannot be deformed at all. Specifically, the rigidity of the outer wall of the roller brush means that the rigidity of the outer wall is large enough, so that the outer wall of the roller brush will not be deformed in the normal working state.

[0131] Specifically, in the embodiment, the end portion of the shaft is made of soft glue material, and the soft glue surface has large friction, which is beneficial to the hair being thrown out.

[0132] It can be understood that the part of the shaft except the end portion can be made of hard glue material.

[0133] The shaft rod and the blade 2 are integrally formed, so that the rolling brush has good structural strength. In the prior art, the shaft rod and the blade 2 of the anti-winding rolling brush are usually assembled together, and there is usually a gap during assembly. If the gap position enters the hair, the hair cannot be separated from the rolling brush. In the embodiment, the shaft rod and the blade 2 are integrally formed, so that the gap between the shaft rod and the blade 2 is avoided, and the effect of preventing hair winding is enhanced.

[0134] The shaft rod and the blade 2 can be integrally formed by double-material injection molding, in-mold injection molding, liquid injection molding, or oil pressure molding.

[0135] Specifically, in the embodiment, the shaft rod and the blade 2 are integrally formed by double-color injection molding or in-mold injection molding.

[0136] The shaft rod is made of PC or ABS or PA, or the shaft rod 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.

[0137] The blade 2 is made of TPU or TPE or silicone or rubber.

[0138] As a first implementation of the embodiment, the rolling brush includes a shaft rod and an end cover 12, the end cover 12 is arranged on the shaft rod to form a free end of the rolling brush, and an end surface of the end cover 12 is arranged to be inclined.

[0139] By arranging the end cover 12 and arranging the end surface of the end cover 12 to be inclined, the end surface is formed to be inclined. When the hair is wound around the end of the shaft rod, the hair will slide along the inclined end surface as it gradually tightens, and eventually come off the shaft rod, solving the problem of the end of the shaft rod being easily wound with hair. Moreover, after the hair comes off the shaft rod, it will be easily thrown out by the rotation of the rolling brush by arranging at least one end surface of the shaft rod to be inclined relative to the central axis of the shaft rod, which facilitates the hair entering the dust box from the main brush bin and improves the use experience.

[0140] The end surface of the end cover 12 is arranged to be inclined relative to the central axis of the shaft rod.

[0141] The shaft rod can be a cylindrical structure, and the shaft rod extends along a straight line. The end cover 12 is arranged on the free end of the shaft rod.

[0142] The end cover 12 is arranged on the free end of the shaft rod.

[0143] Specifically, the end surface of the end cover 12 is arranged to be inclined relative to the central axis of the shaft rod, that is, the end surface of the end cover 12 is neither parallel to the central axis of the shaft rod nor perpendicular to the central axis of the shaft rod, that is, the central axis of the shaft rod and the end surface form an angle other than 90 degrees.

[0144] In one embodiment, the end face arranged obliquely relative to the central axis of the shaft is an arc face, so that the end face is smooth, and the hair can slide smoothly on the end face.

[0145] In one embodiment, the end face arranged obliquely relative to the central axis of the shaft is an arc face, so that the end face is smooth, and the hair can slide smoothly on the end face.

[0146] In one embodiment, the end face arranged obliquely relative to the central axis of the shaft is a plane, which can also ensure that the hair slides smoothly on the end face.

[0147] In one embodiment, the end face arranged obliquely relative to the central axis of the shaft is a plane, which can also ensure that the hair slides smoothly on the end face.

[0148] In one embodiment, the end faces of the two end caps 12 arranged oppositely on the roller brush are arranged in the same oblique direction, and the two oppositely arranged roller brushes rotate at the same speed and in the same direction.

[0149] In one embodiment, the end faces of the two end caps 12 arranged oppositely on the roller brush are arranged in the same oblique direction, and the two oppositely arranged roller brushes rotate at the same speed and in the same direction.

[0150] In one embodiment, the two oppositely arranged roller brushes have a speed difference, which further improves the ability to remove hair entanglement.

[0151] As shown in FIGS. 1, 4 and 5, in the present embodiment, the roller brush assembly includes two roller brushes, i.e., a first roller brush 5 and a second roller brush 7. The first roller brush 5 and the second roller brush 7 are oppositely arranged along the axial direction. 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, i.e., the right end in FIG. 1. The end cap 12 of the second roller brush 7 is located at the free end of the shaft of the second roller brush 7, i.e., the left end.

[0152] The end cap 12 of the first roller brush 5 and the end cap 12 of the second roller brush 7 are both arranged obliquely relative to the central axis of the shaft, which can enable the first roller brush 5 and the second roller brush 7 to have good ability to remove hair entanglement and improve the user experience.

[0153] In one embodiment, the two oppositely arranged roller brushes have a speed difference, which further improves the ability to remove hair entanglement.

[0154] As a second implementation of the present embodiment, the roller brush assembly further includes a first blocking member 8, at least a portion of which is located between the oppositely arranged roller brushes.

[0155] By setting the first barrier 8 and locating at least a part of the first barrier 8 between the oppositely arranged rolling brushes, when the hair wound on the rolling brushes follows the rolling brushes to rotate, the hair is blocked by the hook and changes the moving direction, the hair is diverted to move towards the dust collecting port 91 side, and then is sucked into the dust box by the fan, so that the effect of removing the hair wound on the rolling brushes is achieved.

[0156] As shown in FIGS. 6-8, in the second embodiment, the rolling brush assembly includes two rolling brushes, i.e. the first rolling brush 5 and the second rolling brush 7. The first rolling brush 5 and the second rolling brush 7 are oppositely arranged along the axial direction. Specifically, the first rolling brush 5 and the second rolling brush 7 are coaxially arranged. At least a part of the first barrier 8 is located between the end faces of the first rolling brush 5 and the second rolling brush 7.

[0157] As shown in FIGS. 6 and 7, the rolling brush assembly includes a rolling brush cabin. The first barrier 8 is arranged on the inner wall of the rolling brush cabin, so that the first barrier 8 can be stably connected, and a part of the first barrier 8 can extend between the end faces of the first rolling brush 5 and the second rolling brush 7.

[0158] The rolling brush assembly includes a rolling brush cabin. The rolling brush cabin is provided with a dust collecting port 91 for communicating with the dust box. The first barrier 8 is arranged on the inner wall of the rolling brush cabin away from the dust collecting port 91, and is oppositely arranged with the dust collecting port 91, so that the hair blocked by the first barrier 8 can enter the dust box in sequence.

[0159] Specifically, the first barrier 8 and the dust collecting port 91 are oppositely arranged along the radial direction of the rolling brush.

[0160] Specifically, the dust and sundries are sucked into the main brush cabin through the dust inlet, and then enter the dust box through the dust collecting port 91.

[0161] As shown in FIG. 9, the first barrier 8 includes a connecting section 81 and a blocking section 82. The connecting section 81 is connected to the inner wall of the rolling brush cabin. The blocking section 82 is connected to the connecting section 81. The extension direction of the blocking section 82 is different from the extension direction of the connecting section 81.

[0162] By arranging the connecting section 81, the first barrier 8 can be stably fixed in the main brush cover 9. By making the extension direction of the blocking section 82 different from the extension direction of the connecting section 81, the connecting section 81 can extend between the oppositely arranged rolling brushes, thereby playing a role in blocking the hair.

[0163] Specifically, the blocking section 82 extends perpendicularly to the axial direction of the rolling brush between the oppositely arranged rolling brushes.

[0164] As shown in FIG. 9, the connecting section 81 is provided with an arc surface for connecting with the inner wall of the main brush cover 9, which is fitted on the arc-shaped inner wall of the main brush cover 9 along the circumferential direction of the roller brush, and the curvature of the arc surface of the connecting section 81 is matched with the curvature of the arc-shaped inner wall of the main brush cover 9, so as to realize close fitting and connection, which can be connected by means of gluing.

[0165] As shown in FIG. 9, the blocking section 82 is connected to the connecting section 81, and 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, and the extension direction of the blocking section 82 is perpendicular to the axial direction of the roller brush and extends into the opposite roller brushes.

[0166] Among them, one end of the blocking section 82 away from the connecting section 81 extends to the central axis of the roller brush.

[0167] The roller brush assembly includes a support, and the support includes a sleeve rod 41. The roller brush is sleeved on the sleeve rod 41, so that the gos milk can stably rotate on the sleeve rod 41.

[0168] The sleeve rod 41 includes an inner rod and an outer rod. The outer rod is sleeved on the outer circumferential side of the inner rod. The inner rod is sleeved with a bearing 42 and connected to the inner wall of the outer rod through the bearing 42. By arranging the bearing 42 between the outer rod and the inner rod, the relative rotation between the inner rod and the outer rod can be more stable, and the wear between the outer rod and the inner rod is also reduced.

[0169] Among them, the outer rod and the body of the frame are in an integrated structure, and a section of the inner rod can be rotatably arranged in the outer rod.

[0170] 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. A section of the inner rod away from the driving component penetrates out of the outer rod. A rubber core is fixedly sleeved on the section of the inner rod penetrating out of the outer rod. The shaft of the roller brush is sleeved on the rubber core and the outer rod. The rubber core is fixedly connected with the shaft in the circumferential direction, so that the rubber core can drive the shaft 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 to rotate.

[0171] Among them, the inner ring of the bearing 42 is sleeved on the outer circumferential wall of the inner rod, and the outer ring of the bearing 42 is connected to the inner circumferential wall of the outer rod.

[0172] As shown in FIGS. 10-13, the bearing 42 is at least two, and the at least two bearings 42 are arranged along the axial direction of the inner rod, which can further ensure that the inner rod stably rotates in the outer rod.

[0173] Specifically, the number of bearings 42 is two. One bearing 42 is arranged on the inner wall of one end of the outer rod, and the other bearing 42 is arranged on the inner wall of the other end of the outer rod.

[0174] The bearing 42 is an oil-containing bearing 42 or a ball bearing 42, or both, to ensure good rotation stability.

[0175] Specifically, in this embodiment, both bearings 42 are oil-containing bearings 42. The oil-containing bearing 42 has good wear resistance, is a powder metallurgy material, and can be customized to various shapes to meet different design spaces. The two bearings 42 are the same size, which saves space and simplifies the assembly relationship, making the transmission more stable and reliable.

[0176] The two supports have the same or different sleeve connecting rods 41. In the case of different sleeve connecting rods 41, it can be prevented from being mistaken and avoid assembly errors to ensure product yield.

[0177] The brush is provided with a sleeve hole and is sleeved on the sleeve connecting rod 41. The sleeve holes of different brushes are the same or different. In the case of different sleeve holes, it can be prevented from being mistaken and avoid assembly errors to ensure product yield.

[0178] As shown in FIGS. 13-16, in this embodiment, the brush assembly includes two supports and two brushes, i.e., a first support 4 and a second support 6, and a first brush 5 and a second brush 7. The first brush 5 is assembled on the first support 4, and the second brush 7 is assembled on the second support 6.

[0179] Specifically, the first brush 5 is provided with a first sleeve hole 51 and is sleeved on the sleeve connecting rod 41 of the first support 4 through the first sleeve hole 51. The cross section of the first sleeve hole 51 is adapted to the cross section of the sleeve connecting rod 41 of the first support 4. The second brush 7 is provided with a second sleeve hole 71 and is sleeved on the sleeve connecting rod 41 of the second support 6 through the second sleeve hole 71. The cross section of the second sleeve hole 71 is adapted to the cross section of the sleeve connecting rod 41 of the second support 6. The cross section of the first sleeve hole 51 is different from the cross section of the second sleeve hole 71, and the cross section of the sleeve connecting rod 41 of the first support 4 is different from the cross section of the sleeve connecting rod 41 of the second support 6.

[0180] Specifically, as shown in FIG. 13, the cross section of the first sleeve hole 51 is plum blossom-shaped, i.e., the first sleeve hole 51 is a plum blossom hole. As shown in FIG. 14, the cross section of the sleeve connecting rod 41 of the first support 4 is also plum blossom-shaped and is adapted in size and shape to the first sleeve hole 51. After the sleeve connecting rod 41 of the first support 4 is inserted into the first sleeve hole 51, the sleeve connecting rod 41 of the first support 4 is in contact with the plum blossom structure of the first sleeve hole 51 in the circumferential direction through the plum blossom structure, thereby driving the first brush 5 to rotate.

[0181] Specifically, as shown in FIG. 15, the second sleeve hole 71 is rectangular in cross section, i.e., the second sleeve hole 71 is a rectangular hole. As shown in FIG. 16, the sleeve rod 41 of the second support 6 is also rectangular in cross section and has a size and shape that are adapted to the second sleeve hole 71. After the sleeve rod 41 of the second support 6 is inserted into the second sleeve hole 71, the sleeve rod 41 of the second support 6 is in abutment with the second sleeve hole 71 in the circumferential direction by virtue of the rectangular structure, thereby driving the second roller brush 7 to rotate. The cross section of the first sleeve hole 51 and the cross section of the sleeve rod 41 of the first support 4 are plum blossom-shaped, and the cross section of the second sleeve hole 71 and the cross section of the sleeve rod 41 of the second support 6 are rectangular. The cross section shapes and sizes are different, so that the sleeve rod 41 of the first support 4 cannot be inserted into the second sleeve hole 71, and the sleeve rod 41 of the second support 6 cannot be inserted into the first sleeve hole 51, thereby forming a fool-proof effect.

[0182] As shown in FIGS. 17-19, as a third embodiment of the present embodiment, the free ends of the at least two roller brushes are obliquely arranged toward the dust collection port 91, so that dust is more easily driven by the roller brushes into the dust collection port 91 and then sucked into the dust box, thereby improving the cleaning effect.

[0183] Specifically, the opposite ends of the two opposite roller brushes, i.e., the free ends of the two roller brushes, are obliquely arranged toward the dust collection port 91.

[0184] Specifically, the roller brush is substantially cylindrical in structure, and the roller brush extends linearly along the central axis thereof.

[0185] Specifically, the free ends of the roller brushes extend toward the dust collection port 91. The internal space of the main brush cover 9 is in communication with the dust box through the dust collection port 91. The flow area of the dust collection port 91 is relatively small, so the wind speed is relatively fast. By arranging the free ends of the roller brushes to extend toward the dust collection port 91, dust can be driven to the dust collection port 91 by the rotation of the roller brushes and then more easily sucked into the dust box.

[0186] Specifically, the dust collection port 91 is arranged at a middle position of the main brush cover 9 in the transverse direction, and the connecting end 11 of the roller brush is located at one end of the main brush cover 9, and the free end of the roller brush extends toward the dust collection port 91 at the middle of the main brush cover 9.

[0187] Specifically, the first roller brush 5 is located at a first side of the dust collection port 91, and the second roller brush 7 is located at a second side of the dust collection port 91. The free end of the first roller brush 5 is obliquely arranged toward the dust collection port 91, and the free end of the second roller brush 7 is obliquely arranged toward the dust collection port 91, so that the first roller brush 5 and the second roller brush 7 are arranged at an angle. Dust can be simultaneously driven to the dust collection port 91 from two directions by the first roller brush 5 and the second roller brush 7, thereby further improving the cleaning effect.

[0188] Specifically, the first roller brush 5 and the second roller brush 7 are arranged substantially symmetrically left and right.

[0189] The first side and the second side are respectively the left and right sides of the dust collecting port 91, and can be understood as the left side of the dust collecting port 91 for the first side and the right side of the dust collecting port 91 for the second side.

[0190] The free end of the first roller brush 5 and the free end of the second roller brush 7 are two ends opposite in the left-right direction.

[0191] One end of the bracket is connected to the driving device, and the other end is inclined towards the dust collecting port 91.

[0192] The roller brush can rotate on the bracket with the central axis of the roller brush as the rotation center.

[0193] Specifically, the first roller brush 5 is rotationally arranged on the first bracket 4, and the second roller brush 7 is rotationally 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 collecting port 91. The first roller brush 5 can rotate on the first bracket 4 with the central axis of the first roller brush 5 as the rotation center, and the second roller brush 7 can rotate on the second bracket 6 with the central axis of the second roller brush 7 as the rotation center, thereby ensuring good rotational stability of the first roller brush 5 and the second roller brush 7.

[0194] The first roller brush 5 is rotationally sleeved on the sleeving rod 41 of the first bracket 4. The first roller brush 5, the sleeving rod 41 of the first bracket 4, and the driving member of the driving device directly connected to the sleeving rod 41 are coaxially arranged, and the axis extends towards the dust collecting port 91. That is, the sleeving rod 41 of the first bracket 4 is arranged obliquely relative to the side wall of the roller brush cover.

[0195] The second roller brush 7 is rotationally sleeved on the sleeving rod 41 of the second bracket 6. The second roller brush 7, the sleeving rod 41 of the second bracket 6, and the driving member of the driving device directly connected to the sleeving rod 41 are coaxially arranged, and the axis extends towards the dust collecting port 91. That is, the sleeving rod 41 of the second bracket 6 is arranged obliquely relative to the side wall of the roller brush cover.

[0196] The main brush cover 9 is provided with a dust inlet, and the opening angle of the dust inlet is adapted to the angle formed by the two roller brushes.

[0197] The two roller brushes arranged opposite to each other at the free ends form an obtuse angle, that is, the angle formed by the first roller brush 5 and the second roller brush 7 is an obtuse angle. The dust inlet corresponds to the obtuse angle structure.

[0198] According to an embodiment of the present disclosure, an automatic cleaning device is provided, which comprises the roller brush assembly as described above.

[0199] According to an embodiment of the present disclosure, a cleaning system is provided, which comprises the roller brush assembly as described above or the automatic cleaning device as described above. The cleaning system further comprises a base station, wherein the base station is used to provide maintenance for the automatic cleaning device.

[0200] The common roll brush 100 in the prior art is usually connected with the driving device in the cabin 300 through a rotating shaft. When the roll brush 100 interferes with the linear objects such as hair, the long and soft hair will spontaneously form many different configurations in the natural state due to the characteristics of long length and soft material. After the interference of the roll brush 100, the hair is more likely to be self-wrapped. The hair is easy to be wrapped on the roll brush 100 and the rotating shaft of the roll brush 100. After a long time of use, too much hair wrapped on the roll brush 100 will cause the deformation of the roll brush 100 and increase the loss of the driving part of the roll brush 100, thereby reducing the service life of the cleaning device. The hair wrapped on the rotating shaft is not easy to be sucked into the air duct, which affects the cleaning efficiency. Therefore, the hair on the roll brush 100 and the rotating shaft needs to be cleaned manually regularly, which is time-consuming and laborious. The hair entering the cabin 300 will pollute the environment in the cabin and even cause damage to the parts in the cabin, thereby affecting the service life of the device.

[0201] As shown in FIGS. 20-31, a roll brush 100 is provided for a cleaning device. The roll brush 100 includes a roll brush body 201 and a second blocking piece 202. The roll brush body 201 includes a shaft 2011 and blades 2012. The blades 2012 are arranged on the outer circumferential side of the shaft 2011. The second blocking piece 202 is arranged at the end of the roll brush body 201. A part of the blades 2012 is inclined to the axis direction of the shaft 2011 and inserted into the second blocking piece 202.

[0202] The roll brush 100 is arranged at the end close to the cabin 300 through the annular second blocking piece 202. A part of the blades 2012 is inclined to the axis direction of the shaft 2011 and inserted into the second blocking piece 202. A plurality of blades 2012 are arranged on the shaft 2011. The hair is wrapped on the plurality of blades 2012 to form a hair ring close to a circle. The outer diameter of the second blocking piece 202 is greater than the outer diameter of the position of the plurality of blades 2012 connected with the second blocking piece 202. When the hair on the blades 2012 moves to the end in the axial direction of the roll brush body 201, the hair is blocked by the second blocking piece 202 and cannot be wrapped on the shaft connected with the roll brush 100. The hair is limited on the blades 2012 with a larger outer diameter. The hair is difficult to form a ball and can be better sucked into the air duct, thereby improving the cleaning effect. The second blocking piece 202 is arranged at the end close to the cabin 300, which can prevent the hair from entering the cabin 300, prolong the service life of the device and improve the use experience.

[0203] In an embodiment, as shown in FIGS. 20-23, the blade 2012 includes a blade body 122 and an extension 121 arranged at an end of the blade body 122, and a portion of the extension 121 is inserted into the second barrier 202, and the extension 121 is located inward of an outer edge of the blade body 122 in a radial direction of the roller brush body 201, and the extension 121 is located inward of an outer edge of the second barrier 202.

[0204] It can be understood that the root of the blade 2012 is narrowed to be inserted into the second barrier 202, i.e., the extension 121 is integrated with the blade body 122, and the outer diameter of the second barrier 202 is greater than that of the extension 121, and during the movement of the hair on the blade 2012 along the axial direction of the roller brush body 201, the hair is slightly tightened at the position of the extension 121 until it contacts the second barrier 202, and the hair cannot continue to move to the end due to the stop of the second barrier 202, and the hair can be limited at the position of the extension 121, and the diameter of the hair loop wound at the position of the extension 121 is slightly smaller than that of the hair loop wound at the position of the blade body 122, and the hair loop wound at the position of the extension 121 still has a relatively large diameter, so that the hair cannot be self-wound, which greatly reduces the situation that the hair is tightly wound on the roller brush 100, reduces the situation that the hair tightly wound on the roller brush 100 causes the deformation of the roller brush 100, reduces the frequency of manual cleaning of the hair on the roller brush 100, and improves the user satisfaction.

[0205] In an embodiment, as shown in FIGS. 20-23, at least a portion of the extension 121 has a radial height lower than that of the second barrier 202.

[0206] In an embodiment, as shown in FIGS. 20-23, the plurality of blades 2012 are arranged along the circumferential direction of the shaft 2011, and the radial distance between the extension 121 and the shaft 2011 is less than the radial distance between the outer edge of the blade body 122 and the shaft 2011.

[0207] It can be understood that the plurality of blades 2012 are arranged on the outer circumferential side of the shaft 2011 and along the circumferential direction of the shaft 2011, and the driving device drives the shaft 2011 and the blades 2012 to rotate to realize the cleaning of the surface to be cleaned.

[0208] Specifically, the blade 2012 can be arranged along the axial direction of the shaft 2011, and can also extend in a spiral shape along the axial direction of the shaft 2011.

[0209] In an embodiment, as shown in FIGS. 20-23, at least a portion of the outer edge of the extension 121 is a guide segment arranged between the second barrier 202 and the blade body 122.

[0210] It can be understood that the part between the extension 121 inserted into the second blocking piece 202 and the blade body 122 is smoothly connected through the guide section, that is, there is no obvious gap or break between the part of the blade 2012 between the extension 121 inserted into the second blocking piece 202 and the blade body 122, and the two are smoothly connected, so as to ensure that the hair can be stably moved along the blade 2012 until being stopped by the second blocking piece 202.

[0211] The guide section includes a slanted line section and / or an arc section.

[0212] In an implementation, the guide section is a slanted line section, at least part of the slanted line section is located between the second blocking piece 202 and the blade body 122, the slanted line section extends from one end of the blade body 122 to the second blocking piece 202 and is inserted into the second blocking piece 202, and the slanted line section is inclined to the direction close to the shaft 2011, so that the hair can contact the second blocking piece 202 when moving from the blade body 122 to the position of the slanted line section, and the hair at the position of the slanted line section is axially stopped along the shaft 2011.

[0213] In an implementation, the guide section is an arc section, at least part of the arc section is located between the second blocking piece 202 and the blade body 122, the arc section extends from one end of the blade body 122 to the second blocking piece 202 and is inserted into the second blocking piece 202, and the arc section is inclined to the direction close to the shaft 2011, so that the hair can contact the second blocking piece 202 when moving from the blade body 122 to the position of the arc section, and the hair at the position of the arc section is axially stopped along the shaft 2011.

[0214] In an implementation, the guide section includes an arc section and a slanted line section, at least part of the slanted line section or at least part of the slanted line section is located between the second blocking piece 202 and the blade body 122, at least one of the arc section and the slanted line section extends from one end of the blade body 122 to the second blocking piece 202 and is inserted into the second blocking piece 202, and at least one of the arc section and the slanted line section is inclined to the direction close to the shaft 2011, so that the hair can contact the second blocking piece 202 when moving from the blade body 122 to the position of at least one of the arc section and the slanted line section, and the hair at the position of at least one of the arc section and the slanted line section is axially stopped along the shaft 2011.

[0215] The arc section can be a concave arc, that is, an inwardly concave arc.

[0216] The arc-shaped section can also be a convex arc, that is, an outward convex arc. When the arc-shaped section is a convex arc, the arc-shaped section can be completely located between the second blocking piece 202 and the blade body 122. A transition section can also be arranged between the arc-shaped section and the second blocking piece 202, and the transition section can be a straight line section, an inclined line section, an arc line section or the like, so as to avoid hair winding in the gap between the convex arc and the second blocking piece 202.

[0217] In an implementation, as shown in FIGS. 20-23, the ratio of the minimum radial distance between the guide section and the shaft 2011 to the radial distance between the outer edge of the blade body 122 and the shaft 2011 is 0.5-0.9.

[0218] It can be understood that the root of the blade 2012 is narrowed to form the extension 121 and is inserted into the second blocking piece 202. During the axial movement of the hair along the roller brush body 201, when the hair moves to the position of the extension 121, the hair ring is slightly tightened until it is in contact with the second blocking piece 202. In order to prevent the diameter of the hair ring on the side of the second blocking piece 202 from being too small to cause the hair to be tightly wound on the blade 2012, the distance between the position where the end of the second blocking piece 202 close to the blade body 122 is in contact with the outer edge of the extension 121 and the shaft 2011 is required to be a certain value, specifically, the ratio of the distance to the distance between the outer edge of the blade body 122 and the shaft 2011 can be 0.5-0.9. This can not only make the hair ring slightly tightened when the hair moves to the position of the extension 121 and then in contact with the second blocking piece 202 to be stopped, but also ensure that the hair ring will not be self-wound due to the too small diameter to affect the hair being sucked into the air duct. The slightly reduced diameter of the hair ring can still be smoothly sucked into the air duct, thereby ensuring the cleaning efficiency.

[0219] In an implementation, as shown in FIGS. 22 and 23, the shaft 2011 is provided with an end plate 2013, and the plurality of blades 2012 are embedded on the end plate 2013 and extend out of the side of the end plate 2013 away from the blade body 122. The second blocking piece 202 is located on the side of the end plate 2013 away from the blade body 122.

[0220] The shaft 2011 is provided with an annular end plate 2013, the end plate 2013 is sleeved on the shaft 2011, the end plate 2013 is connected with the plurality of blade bodies 122, the root of the blade 2012 is narrowed to form the extension 121, the extension 121 protrudes from the end face of the end plate 2013 and is inserted into the second blocking piece 202, and the end of the extension 121 can be located in the second blocking piece 202 or can pass through the second blocking piece 202.

[0221] In an implementation, as shown in FIGS. 22 and 23, the shaft 2011 includes a shaft body 111 and a ring-shaped flange 112 arranged at an end of the shaft body 111, and the second blocking member 202 is sleeved on the ring-shaped flange 112.

[0222] The shaft body 111 can be in a cylindrical structure and arranged in a straight line.

[0223] The ring-shaped flange 112 is arranged at an end of the shaft body 111, the second blocking member 202 is sleeved on the ring-shaped flange 112, the ring-shaped flange 112 and the shaft body 111 can be in an integrated structure or a split structure, and the end plate 2013 can be located at one side of the ring-shaped flange 112.

[0224] The second blocking member 202 and the shaft 2011 can be connected by means of adhesion, sleeving, screwing, clamping, mortise and tenon, magnetic attraction, etc., so that the second blocking member 202 can rotate with the shaft 2011.

[0225] In an implementation, as shown in FIG. 24, the second blocking member 202 includes second hair bundles 2022 arranged circumferentially along the shaft 2011, and the extension 121 is inserted into the gap between the second hair bundles 2022.

[0233] The surface of the second hair bundle 2022 is smooth and free of burrs, reducing the friction between the hair and the second hair bundle 2022, so that the hair can slide relative to the second hair bundle 2022, and the hair is prevented from being entangled on the second hair bundle 2022.

[0236] The inner wall of the annular part 2021 is finally connected with the shaft 2011, and the outer wall of the annular part 2021 extends away from the shaft 2011, forming a stop for the hair moving towards the inside of the cabin.

[0239] The second blocking piece 202 is made of felt material, and the felt is made of animal hair or fiber, and has good elasticity, sealing property and wear resistance, and can also have a damping effect.

[0240] In an implementation, the second blocking piece 202 and the shaft 2011 can be integrally formed or can be a split structure.

[0241] In an implementation, the second blocking piece 202 and the shaft 2011 can be detachable or can be fixedly connected.

[0242] In an implementation, as shown in FIGS. 26-30, the cleaning device includes a cabin 300 for accommodating the roller brush 100, and the second blocking piece 202 is located between the shaft 2011 and the cabin 300 and fills the gap between the shaft 2011 and the cabin 300, so as to form a stop for the hair moving in the direction of the gap.

[0243] In an implementation, as shown in FIGS. 27-30, the blade 12 does not contact the cabin 3, and the blocking piece 2 interferes with the cabin 3.

[0244] It can be understood that the extension 121 is in small-gap fitting with the cabin 3, and the second blocking piece 202 is in interference fitting with the inner wall of the cabin 300, so that the second blocking piece 202 is always in close contact with the inner wall of the cabin 300 during rotation of the second blocking piece 202 with the roller brush body 201, thereby guaranteeing the sealing effect.

[0245] In an implementation, as shown in FIG. 30, at least a portion of the second blocking piece 202 has elasticity, and the second blocking piece 202 is always in close contact with the cabin 300 during relative movement of the second blocking piece 202 and the cabin 300.

[0246] As shown in FIGS. 26-31, a roller brush assembly 200 is provided, which includes any one of the roller brushes 100 described above, and the roller brush 100 is used to be connected with a driving device, so that the driving device drives the roller brush 100 to rotate.

[0247] The roller brush assembly 200 includes a cabin 300, the roller brush 100 is arranged in the cabin 300, the driving device can be arranged in the cabin 300, the driving device is power-connected with the roller brush 100 through a rotating shaft, and drives the roller brush 100 to rotate and interfere with a surface to be cleaned.

[0248] The cabin 300 has a good protective effect on the driving device and the transmission device, reduces pollution in the cabin 300, and is conducive to prolonging the service life and reliability.

[0249] In an embodiment, as shown in FIGS. 27-31, the cabin 300 comprises a main brush cabin 31 and a main brush cover 32, which enclose a cavity for accommodating the roller brush 100, and enclose a matching cavity 33 for accommodating the second blocking piece 202.

[0250] Specifically, the cabin 300 can comprise a main brush cabin 31 and a main brush cover 32 that are detachably connected, facilitating assembly, disassembly and maintenance. The brush cabin and the main brush cover 32 can be detachably connected by at least one of a screw, a clamping structure, a mortise and tenon structure, and a magnetic attraction structure.

[0251] As shown in FIGS. 28-30, the cabin 300 is provided with a main brush opening 34 through which the blade 2012 interferes with the surface to be cleaned, and a matching cavity 33 located on the outer circumferential side of the second blocking piece 202 and interfering with the second blocking piece 202.

[0252] The main brush cabin 31 and the main brush cover 32 enclose a cavity for accommodating the roller brush 100, and the cavity has an opening, i.e., the main brush opening 34, through which a part of the roller brush 100 contacts the surface to be cleaned.

[0253] The main brush cabin 31 and the main brush cover 32 enclose a matching cavity 33 for accommodating the second blocking piece 202. The matching cavity 33 is specifically enclosed by the shaft 2011 and the cabin 300. The shape of the matching cavity 33 is adapted to the shape of the second blocking piece 202. The shape of the matching cavity 33 is a ring-shaped cavity slightly smaller than the second blocking piece 202, and the outer edge of the second blocking piece 202 always fits the matching cavity 33.

[0254] The maximum distance from the outer edge of the blade body 122 to the axis of the shaft 2011 is greater than the maximum distance from the outer wall of the main brush cover 32 to the axis of the shaft 2011, so that the blade body 122 can interfere with the surface to be cleaned through the main brush opening 34.

[0255] The number of roller brushes 100 can be one, two, three, four, or other numbers. The material, size and number of the roller brushes 100 can be set according to specific needs to meet different cleaning needs.

[0256] In an embodiment, the roller brush assembly 200 comprises at least one roller brush 100, and both ends of the roller brush 100 are connected with a rotating shaft, and both ends of the roller brush 100 are provided with a second blocking piece 202.

[0257] When the roller brush 100 is a double full-arm roller brush 100, one end of the roller brush 100 is connected to the driving device through a rotating shaft, and the other end of the roller brush 100 is rotatably connected to the cabin 300. When the roller brush 100 rotates and interferes with the surface to be cleaned, the hair on the blade 2012 can move to either end of the roller brush 100. Therefore, the second blocking piece 202 can be arranged at both ends of the roller brush 100 to block the moving hair from winding around the rotating shaft.

[0258] In an implementation, the roller brush assembly 200 includes at least one roller brush 100, and the roller brush 100 is connected with a rotating shaft at one end, and the second blocking piece 202 is arranged at the end of the roller brush 100 close to the driving device.

[0259] When the roller brush 100 is a cantilever roller brush 100, one end of the roller brush 100 is connected to the driving device through a rotating shaft, and the other end of the roller brush 100 is suspended. When the roller brush 100 rotates and interferes with the surface to be cleaned, the hair on the blade 2012 can move to either end of the roller brush 100. When the hair on the blade 2012 moves away from the rotating shaft, it can be sucked into the air duct or separated from the roller brush 100. Therefore, the second blocking piece 202 can be arranged at the end of the roller brush 100 close to the rotating shaft to block the moving hair from winding around the rotating shaft.

[0260] When the number of cantilever roller brushes 100 is two or more, at least two roller brushes 100 are arranged in opposite directions along their own axes. The differential rotation of the at least two roller brushes 100 can cause the hair to be pulled between the roller brushes 100, preventing the hair from forming a ball, better sucking into the air duct, improving the cleaning effect, and reducing the hair winding around the roller brush 100. The hair is easily thrown out or even broken under the pulling of the roller brush 100, greatly reducing the situation of the hair winding around the roller brush 100, reducing the situation of the roller brush 100 deforming due to the hair winding around the roller brush 100, reducing the wear of the driving element of the roller brush 100, prolonging the service life of the cleaning device, reducing the frequency of manual cleaning of the hair on the roller brush 100, and improving user satisfaction.

[0261] A cleaning system is provided, including a cleaning device and a base station. The cleaning device includes any one of the roller brushes 100 described above, or includes any one of the roller brush assemblies 200 described above, and the base station provides maintenance for the cleaning device.

[0262] The roller brush 100 is applied to a cleaning system, which includes a cleaning device and a base station. The cleaning device can be a self-moving cleaning robot or other types of cleaning robots that meet the requirements. Specifically, the cleaning device can include a sweeper, a sweeper-mop all-in-one machine, etc.

[0263] The cleaning device comprises a roller brush 100 or a roller brush assembly 200 arranged below the cleaning device and capable of achieving cleaning of dirt on a surface to be cleaned, and the roller brush 100 can be a dry cleaning assembly.

[0264] As shown in FIG. 32, a roller brush device is provided for a cleaning device, and the roller brush device comprises a roller brush assembly 200, a transmission part 302, and a driving part 303. The roller brush assembly 200 comprises at least a first roller brush 1011 and a second roller brush 1012. The transmission part 302 comprises a first transmission mechanism 21 and a second transmission mechanism 22. The first transmission mechanism 21 is connected to the first roller brush 1011, and the second transmission mechanism 22 is connected to the second roller brush 1012. The driving part 303 drives the first transmission mechanism 21 and the second transmission mechanism 22 to drive the first roller brush 1011 and the second roller brush 1012 to rotate. The driving part 303 drives the second transmission mechanism 22 to drive the second roller brush 1012 to rotate. There is a speed difference between the first roller brush 1011 and the second roller brush 1012.

[0265] Embodiments of the present disclosure provide a cleaning device comprising a device main body and a cleaning system. The cleaning system comprises a roller brush device comprising a roller brush assembly 200 arranged below the device main body and capable of achieving cleaning of dirt on a surface to be cleaned. The roller brush device can be a dry cleaning assembly.

[0266] The conventional roller brush in the prior art is usually an integral whole. When the roller brush interferes with hair and the like linear objects, the hair and the like linear objects have the characteristics of long length and soft material. The long and soft hair spontaneously forms many different configurations in a natural state. After being interfered by the roller brush, the hair is more likely to be self-wrapped and is easily wrapped on the roller brush and the rotating shaft of the roller brush. After long-time use, too much hair wrapped on the roller brush causes the deformation of the roller brush and increases the loss of the driving part of the roller brush, thereby reducing the service life of the cleaning device. After the hair is separated from the roller brush, the hair is easily twisted into a bundle and is not easily sucked into the air duct, thereby affecting the cleaning efficiency. Therefore, the hair on the roller brush needs to be manually cleaned regularly, which is time-consuming and laborious.

[0267] In view of this, a roller brush device is provided, which comprises a roller brush assembly 200, a transmission part 302, and a driving part 303. The driving part 303 drives the first roller brush 1011 to rotate through the first transmission mechanism 21, and the driving part 303 drives the second roller brush 1012 to rotate through the second transmission mechanism 22. The rotating speeds of the two roller brushes are different.

[0268] It can be understood that the rolling brush device includes at least two rolling brushes, and the differential rotation of the at least two rolling brushes can cause the hair to be pulled between the rolling brushes, so that the hair cannot be bunched, can be better sucked into the air duct, and the cleaning effect is improved. The hair is easily broken under the pulling of the rolling brush, greatly reduces the situation that the hair is entangled on the rolling brush, reduces the situation that the rolling brush is deformed due to the entanglement of the hair on the rolling brush, reduces the loss of the rolling brush driving part, prolongs the service life of the cleaning equipment, reduces the frequency of manual cleaning of the hair on the rolling brush, and improves the user satisfaction.

[0269] The number of rolling brushes can be two, three, four, or other numbers, and the rotation speeds of adjacent two rolling brushes are different, so that the hair is pulled between the rolling brushes with differential rotation. The material, size and number of the rolling brush can be set according to specific needs to meet different cleaning needs.

[0270] It can be understood that the rolling brush assembly 200 includes a first rolling brush 1011 and a second rolling brush 1012, the first rolling brush 1011 rotates at a first rotation speed, and the second rolling brush 1012 rotates at a second rotation speed. The first rotation speed and the second rotation speed are different, so that when the first rolling brush 1011 and the second rolling brush 1012 contact the hair, the hair is stretched and straightened due to the difference in rotation speed of the two, and it is difficult to bunch and entangle on the rolling brush, and it is more easily sucked into the air duct.

[0271] It can be understood that the hair is easily broken when pulled between the two rolling brushes with differential rotation, the length of the broken hair is shortened, and the hair is not easily entangled on the rolling brush and is more easily sucked into the air duct.

[0272] In specific implementation, when the rolling brush with a faster rotation speed first interferes with the linear object, and the rolling brush with a slower rotation speed interferes with the linear object later, the linear object will be pulled between the two rolling brushes, so that the linear object is more inclined to move to the gap between the two rolling brushes, and is not easily entangled on the rolling brush and is more easily sucked into the air duct. When the rolling brush with a slower rotation speed first interferes with the linear object, and the rolling brush with a faster rotation speed interferes with the linear object later, the linear object will be more fluffy between the two rolling brushes, and is not easily entangled on the rolling brush and is more easily sucked into the air duct.

[0273] In an implementable manner, as shown in FIG. 32, the rolling brush device further includes a mounting frame 304, the driving part 303 and the transmission part 302 are arranged on the mounting frame 304, and the mounting frame 304 is connected with the equipment main body of the cleaning equipment.

[0274] The rolling brush assembly 200 is arranged on the equipment main body of the cleaning equipment through the mounting frame 304. The rolling brush assembly 200 with a certain interference with the surface to be cleaned sweeps up the dirt on the ground and rolls to the front of the dust suction port between the rolling brush assembly 200 and the dust box, and then is sucked into the air duct and enters the dust box, so as to realize dry cleaning.

[0275] As shown in FIGS. 32-35, the mounting frame 304 can further include a connecting rod, which is connected to the device body through the connecting rod, and an adaptive floating design can be adopted. Under the action of the self-weight of the rolling brush device, the rolling brush assembly 200 can freely swing downward, so that the rolling brush assembly 200 can always contact the surface to be cleaned with a certain pressure. When the surface to be cleaned is uneven, the rolling brush assembly 200 can always closely contact the ground and float with the surface to be cleaned.

[0276] In an embodiment, as shown in FIG. 33, the first rolling brush 1011 and the second rolling brush 1012 can be coaxially arranged, so that the first rolling brush 1011 and the second rolling brush 1012 can interfere with the same linear object to form pulling on the linear object.

[0277] In an embodiment, as shown in FIG. 33, the first rolling brush 1011 and the second rolling brush 1012 can interfere with or not contact each other.

[0278] In this embodiment, the first rolling brush 1011 and the second rolling brush 1012 do not contact each other, and the linear object is tensioned or even broken under the pulling of the differential rolling brushes, so that the linear object is more easily thrown out and sucked into the air duct. The first rolling brush 1011 and the second rolling brush 1012 are separated from each other, so that the linear object cannot be wound between the first rolling brush 1011 and the second rolling brush 1012. A gap is formed between the first rolling brush 1011 and the second rolling brush 1012. The first rolling brush 1011 and the second rolling brush 1012 are in small gap cooperation. The gap is located at the air inlet position of the air duct to prevent air leakage caused by too large gap. The small gap can ensure the gas flow rate between the first rolling brush 1011 and the second rolling brush 1012, so that the linear object is more easily sucked into the air duct.

[0279] In an embodiment, the ratio between the rotation speed of the first rolling brush 1011 and the rotation speed of the second rolling brush 1012 is 0.8-0.99.

[0280] It can be understood that there is a rotation speed difference between the first rolling brush 1011 and the second rolling brush 1012 to form pulling on the linear object during contact with the linear object. In specific implementation, the driving part 303 drives the rolling brush to rotate at least to interfere with the impurities on the surface to be cleaned, and also interferes with the surface to be cleaned. If the difference between the rotation speeds of the two is too large, the friction difference between the rolling brush and the surface to be cleaned will increase the load of the driving part 303. Therefore, the rotation speed difference between the first rolling brush 1011 and the second rolling brush 1012 can meet the requirement of forming pulling on the linear object such as hair, i.e., the ratio between the rotation speed of the first rolling brush 1011 and the rotation speed of the second rolling brush 1012 can be 0.8-0.99.

[0281] In an embodiment, as shown in FIGS. 34 and 35, the driving part 303 further comprises a first driving member 31 and a transmission shaft 23, the output shaft of the first driving member 31 is power connected with the first transmission mechanism 21, the first transmission mechanism 21 is power connected with the second transmission mechanism 22 through the transmission shaft 23; there is a transmission ratio difference between the first transmission mechanism 21 and the second transmission mechanism 22.

[0282] In the above embodiment, in the case that the first transmission mechanism 21 and the second transmission mechanism 22 share one driving member, the driving part 303 comprises the first driving member 31 and the transmission shaft 23, the first transmission mechanism 21 and the second transmission mechanism 22 are power connected through the transmission shaft 23 and are driven by the first driving member 31, that is, the output shaft of the first driving member 31 is power connected with the first transmission mechanism 21 to drive the first rolling brush 1011 to rotate, the first transmission mechanism 21 is power connected with the second transmission mechanism 22 through the transmission shaft 23 to drive the second rolling brush 1012 to rotate, since the transmission ratio of the first transmission mechanism 21 and the transmission ratio of the second transmission mechanism 22 are different, the rotation speed of the first rolling brush 1011 and the rotation speed of the second rolling brush 1012 are different. Through the setting of the transmission shaft 23, the function of driving two rolling brushes to rotate at different speeds can be achieved by one driving member, which reduces the power module, simplifies the structure, has small space occupancy and reduces the cost.

The transmission difference can be achieved through the different structures of the first gear set 211 and the second gear set 221, and the transmission ratio difference can be adjusted through the specific design of the gear structure, number and tooth number.
