It should also be understood that the terms used in the embodiments of the present invention are intended to describe specific implementation schemes, rather than to limit the scope of protection of the present invention. The test methods for which specific conditions are not specified in the following examples are usually carried out under conventional conditions or under the conditions recommended by the manufacturers.

[0074] When numerical ranges are given in the embodiments, it should be understood that unless otherwise specified in the present invention, both endpoints of each numerical range and any value between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present invention are in accordance with the prior art mastery of those skilled in the art and the description of the present invention, and any prior art methods, equipment and materials similar or equivalent to the methods, equipment and materials in the embodiments of the present invention can also be used to implement the present invention.

[0075] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present utility model. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present utility model without substantially changing the technical content.

[0076] To solve the problems existing in the prior art, please refer to Figures 1 to 25 The utility model provides a cleaning brush 200 and a cleaning device 100 and a cleaning system including the cleaning brush 200. The cleaning brush 200 is provided with an isolation mechanism 230. By switching the state of the isolation mechanism 230, the first cleaning operation and the second cleaning operation of the cleaning brush 200 can be switched, thereby improving the technical problem that the existing cleaning brush 200 has poor compatibility with dry cleaning and wet cleaning.

[0077] The cleaning device 100 of the present invention may be a floor scrubber, a cleaning robot, etc., but is not limited thereto. Taking the cleaning robot as an example, refer to Figure 2 and Figure 3 In the utility model, the cleaning device 100 includes a frame 120 and a cleaning brush 200, and the cleaning brush 200 is movably connected and installed on the frame 120, and is used to clean the surface to be cleaned. The way in which the cleaning brush 200 is movably connected and installed on the frame 120 is not limited, as long as the movement requirements of switching between the first cleaning operation and the second cleaning operation can be achieved. And for the purpose of aesthetics or protection of components on the frame 120, the cleaning device 100 further includes a first shell 110 and a second shell 130 respectively covered on the upper and lower sides of the frame 120, but it can be understood by those skilled in the art that if protection or aesthetics are not taken into account, only the frame 120 can be set without the first shell 110 and the second shell 130. The frame 120 is provided with a walking wheel 400, which can be driven by the walking drive device of the cleaning device 100 itself to achieve self-walking, or can be pushed or pulled by the operator to achieve external force-assisted walking.

[0078] See also Figure 5 and Figure 6 , Figure 6 for Figure 5 Cross-sectional view of the AA area. The cleaning brush 200 includes: a roller brush holder 210, a roller brush and an isolation mechanism 230. The structure of the roller brush holder 210 is not limited, for example, it can be a frame type, or it can be a structure similar to a cover shape. In the present embodiment, the roller brush holder 210 is a cover-shaped structure, and has a roller brush mounting cavity 219, and the roller brush is rotatably mounted in the roller brush mounting cavity 219 of the roller brush holder 210. The isolation mechanism 230 is connected to the cleaning device 100 and / or the roller brush holder 210. For example, the isolation mechanism 230 can be installed only on the roller brush holder 210 or the cleaning device 100, or it can be arranged between the cleaning device 100 and the roller brush holder 210, and connected to the cleaning device 100 and the roller brush holder 210 respectively. The isolation mechanism 230 has a first state and a second state. As Figure 5 As shown, in the first state, the isolation mechanism 230 makes the roller brush contact with the surface to be cleaned to perform a first wet cleaning operation. Figure 6 As shown, in the second state, the isolation mechanism 230 isolates the roller brush from the surface to be cleaned to perform a second dry cleaning operation or to perform a second dry cleaning operation after the corresponding roller brush is dried. Therefore, when the cleaning brush 200 of the utility model is in the first wet cleaning operation, the isolation mechanism 230 on the cleaning brush 200 makes the roller brush contact with the surface to be cleaned, and when the second dry cleaning operation is performed, the isolation mechanism 230 on the cleaning brush 200 isolates the roller brush from the surface to be cleaned. The switching between the first cleaning operation and the second cleaning operation can be achieved by the isolation mechanism 230 of the cleaning brush 200 itself, which can improve the technical problem that the existing cleaning brush has poor compatibility with dry cleaning and wet cleaning.

[0079] Please note that Figures 2 to 4 The cleaning device 100 in the utility model may also include conventional components of existing cleaning robots such as universal wheels 500, batteries 300, negative pressure suction system (not shown), sewage tank (not shown) and clean water tank (not shown), but those skilled in the art can understand that the above conventional components can also be used as external components rather than as components of the cleaning device 100 of the utility model.

[0080] In the cleaning brush 200 of the present invention, the specific structure of the roller brush can be various, as long as it can cooperate with the isolation mechanism 230 to achieve the first cleaning operation and the second cleaning operation. Figures 6 to 9In this embodiment, the roller brush includes a first roller brush body 280 and a second roller brush body 290. The first roller brush body 280 and the second roller brush body 290 are rotatably mounted in the roller brush mounting cavity 219 on the roller brush bracket 210, and the rotation axes are parallel to each other. By setting the first roller brush body 280 and the second roller brush body 290, a higher cleaning efficiency can be achieved, and it is also convenient to set different cleaning tasks for the first roller brush body 280 and the second roller brush body 290, for example, one of the first roller brush body 280 and the second roller brush body 290 can be used for sweeping, and the other of the first roller brush body 280 and the second roller brush body 290 can be used for mopping. In this way, a combination of multiple cleaning methods can be achieved through the first roller brush body 280 and the second roller brush body 290 that cooperate with each other, thereby improving the cleaning efficiency.

[0081] See also Figure 8 In this embodiment, the outer periphery of the first roller brush body 280 is coated with a hydrophobic layer 282, and the hydrophobic layer 282 is made of a hydrophobic material, including fluorine / silicon materials (common PTFE, FEP, ECTE, ETFE, PFA, etc. are commonly used weather-resistant insulating hydrophobic coatings), synthetic high molecular melt polymer hydrophobic materials (common polyolefins, polycarbonates, polyamides, polyacrylonitrile, polyesters, fluorine-free acrylates, molten paraffin, etc.). In this embodiment, the hydrophobic layer 282 is composed of polypropylene. The interior of the hydrophobic layer 282 is filled with an elastomer 281. The elastomer 281 can be deformed when the first roller brush body 280 encounters an obstacle to reduce the damage caused to the first roller brush body 280 by the obstacle. The material of the elastomer 281 includes but is not limited to rubber, elastic polyurethane material or plastic resin composite elastic material, as long as it can adapt to the cleaning environment and has elasticity. The outer periphery of the second roller brush body 290 is covered with a hydrophilic layer 291, and the hydrophilic layer 291 is made of a hydrophilic material. The hydrophilic material includes but is not limited to polyester, polyester fiber non-woven fabric, absorbent cotton and other materials, which are hydrophilic and have the ability to adhere to water. In this embodiment, the hydrophilic layer 291 is made of flannel, which can be soft and have strong cleaning ability. It can effectively absorb water stains on the ground and can also better clean stains during wet cleaning.

[0082] The structure of the isolation mechanism 230 in the present invention can be various, such as setting an isolation plate and / or setting a lifting component, etc. In the first state, the roller brush is in contact with the surface to be cleaned to perform a wet first cleaning operation. In the second state, the roller brush is isolated from the surface to be cleaned to perform a dry second cleaning operation or to perform a dry second cleaning operation after drying the corresponding roller brush. Figure 6 and Fig.12In an embodiment of the cleaning brush 200 of the utility model, the isolation mechanism 230 includes an isolation plate 232 and a first drive device 270. The shape of the isolation plate 232 includes but is not limited to a flat plate shape and a cylindrical shape. The isolation plate 232 is movably mounted on the roller brush bracket 210. The movable mounting method includes but is not limited to a sliding mounting and a rotating mounting, or a combination of the two. The isolation plate 232 has a first position and a second position. When the isolation plate 232 is in the first position, it blocks the second roller brush body 290 and the surface to be cleaned. When the isolation plate 232 is in the second position, it moves away from the second roller brush body 290 and the surface to be cleaned. The first drive device 270 is mounted on the roller brush bracket 210, and drives the isolation plate 232 to move between the first position and the second position to perform the first cleaning operation or the second cleaning operation accordingly. It should be noted that in other embodiments, the first drive device 270 can also be mounted on the frame 120 of the cleaning device 100.

[0083] See also Figure 6 to Figure 7 , Figure 6 It is a cross-sectional view of the isolation plate in the first position. Figure 7 It is a cross-sectional view of the isolation plate in the second position. In an embodiment of the cleaning brush 200 of the utility model, the isolation plate 232 is an arc-shaped plate, which is rotatably mounted on the roller brush bracket 210 and coaxially arranged on the outer side of the second roller brush body 290. A cylindrical hole 2322 is arranged at both axial ends or one end of the arc-shaped plate. In this embodiment, taking the cylindrical hole 2322 at one axial end as an example, the cylindrical hole 2322 is coaxially arranged with the arc-shaped plate, and a cylinder (not shown) matching the cylindrical hole 2322 is arranged at the side wall of the roller brush bracket 210 corresponding to the position of the cylindrical hole 2322, and the cylinder is inserted into the cylindrical hole 2322 to form a rotational matching pair. However, it can be understood by those skilled in the art that in other embodiments, a cylinder can also be arranged at both ends or one end of the arc-shaped plate, and a cylindrical hole can be arranged on both sides or one side of the roller brush bracket 210. The arc plate can cover part of the outer circumferential surface of the second roller brush body 290, and rotate between the first position and the second position under the drive of the first driving device 270. The first driving device 270 includes but is not limited to a motor, and a combination of a motor and a reducer. When the arc plate rotates to the first position, the arc plate rotates away from between the second roller brush body 290 and the surface to be cleaned, and the second roller brush body 290 is exposed from the lower part of the roller brush bracket 210 to contact the surface to be cleaned. When the arc plate rotates to the second position, it is isolated between the second roller brush body 290 and the surface to be cleaned, and the lower part of the second roller brush body 290 will not contact the surface to be cleaned, which can prevent the second roller brush body 290 with water stains from wetting the cleaning surface such as the carpet.

[0084] In the cleaning brush 200 of the present invention, the rotation of the arc plate can be driven directly by the first driving device 270, or can be driven by a transmission assembly, which includes but is not limited to a belt drive, a chain drive and a gear drive, considering the compactness of the structure. Fig. 9 In this embodiment, the first driving device 270 drives the arc plate to rotate through the gear assembly. The type and number of gears in the gear assembly are not limited. Considering the reduction ratio and space occupancy rate, in this embodiment, the gear assembly includes a first gear 272 and an arc rack 2321. The arc rack 2321 is arranged on the arc plate, and the axes of the arc rack 2321 and the arc plate coincide with the axis of the second roller brush body 290. The first gear 272 is rotatably mounted on the roller brush bracket 210. It should be noted that in other embodiments, the first gear 272 can also be installed on the frame 120 of the cleaning device 100 or on the output shaft of the first driving device 270. The first gear 272 is meshed with the arc rack 2321 under the drive of the first driving device 270 to drive the arc plate to rotate. This structural form in which the second roller brush body 290, the arc plate, and the arc rack 2321 are coaxially arranged can not only save a lot of space, but also better meet the driving requirements and have high stability. However, in other embodiments, the arc plate may be driven to rotate by a belt transmission assembly, or by a combination of a gear assembly and a belt transmission assembly.

[0085] In order to achieve a more stable power transmission and prevent the two ends of the isolation plate 232 from being out of sync, please refer to Fig. 9 and Fig.14 In an embodiment of the cleaning brush 200 of the utility model, a shaft body 271 is rotatably mounted on the roller brush bracket 210, the axis of the shaft body 271 is parallel to the axis of the second roller brush body 290, an arc-shaped rack 2321 is arranged near the axial ends of the arc-shaped plate, and two first gears 272 are respectively fixedly mounted at the two ends of the shaft body 271, and mesh with the arc-shaped racks 2321 at the two ends of the arc-shaped plate. In this way, when the first driving device 270 drives the first gear 272 at one end of the shaft body 271 to rotate, the first gear 272 near one end of the first driving device 270 meshes with the arc-shaped rack 2321 at the corresponding end of the arc-shaped plate, and drives the first gear 272 at the other end of the shaft body 271 to drive the arc-shaped rack 2321 at the other end of the arc-shaped plate, thereby distributing the driving force to the two ends of the arc-shaped plate, with better synchronization and smoother driving.

[0086] Although the above-mentioned isolation plate 232 is an arc-shaped plate, in some other embodiments of the cleaning brush 200 of the present invention, the isolation plate 232 may also be a flat plate, which is slidably mounted on the roller brush bracket 210. The sliding mounting method includes but is not limited to connecting with a linear slide rail pair. The first drive device 270 is a linear drive device, which includes but is not limited to a cylinder and a screw assembly capable of realizing linear drive, etc. Under the drive of the first drive device 270, the isolation plate 232 moves linearly between the first position and the second position to be withdrawn from or blocked between the second roller brush body 290 and the surface to be cleaned.

[0087] In the cleaning brush 200 of the present invention, the isolation plate 232 can be positioned at the first position and the second position by controlling the first driving device 270. Figure 8 and Fig. 9 In an embodiment of the cleaning brush 200 of the utility model, a limiting structure 217 is provided on the roller brush bracket 210 to limit the isolation plate 232 between the first position and the second position. The limiting structure 217 includes a first limiting body 2171 for limiting the isolation plate 232 in the first position and a second limiting body 2172 for limiting the isolation plate 232 in the second position. The second limiting body 2172 is provided with a receiving cavity 2173, and the end of the isolation plate 232 is inserted into the receiving cavity 2173, which can prevent the isolation plate 232 from being damaged or displaced by colliding with the front end of the isolation plate 232 during walking.

[0088] See also Figure 8 In one embodiment of the cleaning brush 200 of the utility model, a plurality of ribs 283 are arranged on the outer wall of the hydrophobic layer 282, and the plurality of ribs 283 are distributed along the outer periphery of the hydrophobic layer 282 and protrude from the surface of the hydrophobic layer 282. The ribs 283 may be arranged on the surface of the hydrophobic layer 282 in any manner, including but not limited to integral molding. The ribs 283 have a gathering function, and may gather dirt into the grooves between the ribs 283, so as to carry the dirt to a position closer to the suction system, so that the dirt is extracted.

[0089] See also Figure 8In one embodiment of the cleaning brush 200 of the utility model, a dirt suction port 215 is provided on the roller brush support 210, and the ribs 283 are spirally provided on the outer wall of the hydrophobic layer 282, so that during the rolling process of the first roller brush body 280, at least part of the dirt is guided from the groove between two adjacent ribs 283 to the area corresponding to the dirt suction port 215. This arrangement not only has a good collection effect on the dirt, but also can utilize the rotation of the first roller brush body 280 and the groove between the two ribs 283 to guide the dirt, thereby improving the efficiency of adsorbing the dirt. However, in other embodiments, the cleaning brush 200 of the utility model may not be provided with the dirt suction port 215, and the dirt may be sucked through the dirt suction port provided separately on the cleaning device 100.

[0090] Although when the dirt suction port 215 is disposed at one end of the first roller brush body 280, the ribs 283 can also be kept continuous along the axial direction. Fig.12 and Fig.16 In an embodiment of the cleaning brush 200 of the present invention, the sewage suction port 215 is arranged in the area between the two ends of the first roller brush body 280. Considering the adaptability of the rotation direction and the guide position of the first roller brush body 280, along the axial direction of the first roller brush body 280, the rib 283 includes a first area 284 and a second area 285 with opposite rotation directions. The junction position 286 between the first area 284 and the second area 285 is located in the area corresponding to the sewage suction port 215. This arrangement has a two-way guiding effect along the axial direction, which can increase the garbage gathering effect and obtain better cleaning efficiency.

[0091] At the position corresponding to the sewage suction port 215, in order to make the dirt better escape from the grooves between the ribs 283, please refer to Fig.16 In an implementation of the cleaning brush 200 of the present invention, at the junction position 286, the ribs 283 in the first area 284 and the ribs 283 in the second area 285 are arranged alternately along the circumference of the first roller brush body 280, so that the ends of the ribs 283 in the first area 284 can stop the dirt in the groove in the second area 285, so that it can quickly break away from the groove and be sucked into the corresponding suction port 215.

[0092] It should be noted that, in another embodiment, at the junction position (286), the end of the rib (283) in the first area (284) and the end of the rib (283) in the second area (285) are connected one by one, so that along the axial direction of the first roller brush body 280, the rib (283) in each first area (284) is connected to the rib (283) in the corresponding second area (285) to form a V-shaped profile.

[0093] Although the ribs 283 of the present invention can extend radially along the first roller brush body 280, please refer to Figure 8In an implementation of the cleaning brush 200 of the present invention, the tail of the rib 283 is inclined radially outward from the first roller brush body 280 toward the rear of the rotation direction of the first roller brush body 280. This arrangement can reduce damage to the first roller brush body 280 and the surface to be cleaned.

[0094] Please continue reading Figure 8 In an embodiment of the cleaning brush 200 of the utility model, the cleaning brush 200 further includes a third rolling brush body 260, which is rotatably mounted on the rolling brush bracket 210 and squeezes the ribs 283 to clean the entangled objects on the first rolling brush body 280, thereby preventing the entangled objects from affecting the cleaning efficiency of the first rolling brush body 280. The third rolling brush body 260 is arranged on the side of the first rolling brush body 280 away from the surface to be cleaned, and has the same rotation direction as the first rolling brush body 280. At the contact position between the first rolling brush body 280 and the third rolling brush body 260, the linear speed of the third rolling brush body 260 is greater than the linear speed of the first rolling brush body 280, so that the entangled objects can be peeled off from the first rolling brush body 280. In this way, the first rolling brush body 280 can be self-cleaned by the third rolling brush body 260 during operation, and no manual cleaning is required after the work is completed.

[0095] See also Figure 8 and Fig.12 In an embodiment of the cleaning brush 200 of the utility model, the cleaning brush 200 further includes a driving assembly 240, and the driving assembly 240 drives the first rolling brush body 280, the second rolling brush body 290 and the third rolling brush body 260 to rotate. As long as the first rolling brush body 280, the second rolling brush body 290 and the third rolling brush body 260 can be driven to rotate according to the design requirements, the structure and type of the driving assembly 240 are not limited. In this embodiment, the driving assembly 240 includes a first driving motor 241, a first speed change mechanism 243, a second driving motor 242 and a second speed change mechanism 244. The second driving motor 242 drives the first rolling brush body 280 and the third rolling brush body 260 to rotate through the second speed change mechanism 243, and the first driving motor 241 drives the second rolling brush body 290 to rotate through the first speed change mechanism 243. The side of the first rolling brush body 280 close to the surface to be cleaned rotates in opposite directions to the side of the second rolling brush body 290 close to the surface to be cleaned. The dirt suction port 215 is located on the upper side of the second roller brush body 290 and is arranged toward the concave cavity surrounded by the first roller brush body 280, the second roller brush body 290, and the third roller brush body 260. It can be understood by those skilled in the art that the driving assembly 240 may not be provided, and the first roller brush body 280, the second roller brush body 290, and the third roller brush body 260 may be rotated by the driving device provided on the cleaning device 100.

[0096] See also Figure 8 , Fig. 9 and Fig.18In an embodiment of the cleaning brush 200 of the utility model, the cleaning brush 200 further comprises a comb tooth portion 218 for performing a hair removal process on the third roller brush body 260 and / or the second roller brush body 290. The comb tooth portion 218 is arranged on the roller brush bracket 210 and is located on the dirt suction path of the dirt suction port (215), for example, it is arranged near the dirt suction port 215. The comb tooth portion 218 can perform a hair removal process on only the third roller brush body 260 or the second roller brush body 290, or can perform a hair removal process on the third roller brush body 260 and the second roller brush body 290 simultaneously or separately. Specifically, in this embodiment, the comb tooth portion 218 includes a first comb tooth body 2181 and a second comb tooth body 2182, which are respectively arranged on both sides close to the sewage suction port 215, and the first comb tooth body 2181 performs a hair removal process on the third roller brush body 260 to comb the hair on the third roller brush body 260 away from the third roller brush body 260, so that the hair enters the sewage suction port 215 and is extracted. The second comb tooth body 2182 performs a hair removal process on the second roller brush body 290 to comb the hair on the second roller brush body 290 away from the second roller brush body 290, so that the hair enters the sewage suction port 215 and is extracted.

[0097] Along the moving direction of the cleaning brush 200, the arrangement order of the first roller brush body 280 and the second roller brush body 290 may not be limited, but considering that dry sweeping is often performed first and wet mopping is performed later during the cleaning process, please refer to Figure 8 In this embodiment, along the moving direction of the cleaning brush 200 , the first rolling brush body 280 is located in front of the second rolling brush body 290 .

[0098] Although considering the effect of the elastic body 281, the gap between the first roller brush body 280 and the second roller brush body 290 may not be set, it is preferred to refer to Figure 8 In the present embodiment, a gap is set between the first roller brush body 280 and the second roller brush body 290, and the distance of the gap X is greater than or equal to 1 mm and less than or equal to 20 mm. For example, it can be any value between 1 mm and 20 mm, such as 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, etc. When the gap is less than 1 mm, dirt cannot pass through smoothly. When the gap is greater than 20 mm, the pressure loss is large and the vacuum degree cannot be guaranteed. Therefore, the gap setting of 1 mm to 20 mm can not only ensure that dirt can smoothly enter the upper concave cavity from between the first roller brush body 280 and the second roller brush body 290, but also reduce the pressure loss of the suction device and ensure the vacuum degree.

[0099] Although the isolation mechanism 230 of the cleaning brush 200 of the present invention can achieve isolation of the second roller brush body 290 from the object on the surface to be cleaned by the isolation plate 232, in the implementation of the cleaning brush 200 of the present invention, please refer to Figure 6, the isolation mechanism 230 also includes a lifting mechanism 231. In the first state, the lifting mechanism 231 drives the roller brush holder 210 to move downward or rotate, so that at least one of the first roller brush body 280 and the second roller brush body 290 contacts the surface to be cleaned, thereby performing a wet first cleaning operation. In the second state, the lifting mechanism 231 drives the roller brush holder 210 to move upward or rotate, so that at least one of the first roller brush body 280 and the second roller brush body 290 is isolated from the air of the surface to be cleaned and / or the isolation plate 232, thereby performing a dry second cleaning operation, or drying the corresponding wet brushes in the first roller brush body 280 and the second roller brush body 290 before performing a dry second cleaning operation. It should be noted that, if Fig.19 As shown, in other embodiments, the isolation plate 232 may not be provided but only the lifting mechanism 231 may be provided, and the air isolation of at least one of the first roller brush body 280 and the second roller brush body 290 from the surface to be cleaned is achieved only by the action of the lifting mechanism 231.

[0100] The type and structure of the lifting mechanism 231 in the present invention are not limited, including but not limited to a connecting rod mechanism, a linear moving lifting device, a pulley lifting assembly, etc. Figure 6 and Fig.14 In this embodiment, the lifting mechanism 231 includes a second driving device 2311 and a connecting rod lifting mechanism 2312. The second driving device 2311 can be a motor or a combination of a motor and a reducer. The second driving device 2311 is fixedly mounted on the roller brush bracket 210 or the cleaning device 100, and drives the connecting rod lifting mechanism 2312 to operate, so that the driving connecting rod lifting mechanism 2312 abuts against the frame 120 of the cleaning device 100 to lift the roller brush bracket 210. It should be noted that in other embodiments, the roller brush bracket 210 can also be directly lifted by the connecting rod.

[0101] Specifically, see Figure 6 and Fig.15 In this embodiment, the connecting rod lifting mechanism 2312 includes: a first arm body 23121, a second arm body 23123 and a connecting rod 23122. The second driving device bracket 214 and the lifting bracket 213 are fixedly arranged on the roller brush bracket 210. The second driving device 2311 is fixedly installed on the second driving device bracket 214, and the driving shaft is fixedly connected to the middle part of the first arm body 23121. The middle part of the second arm body 23123 is rotatably installed on the lifting bracket 213. One end of the connecting rod 23122 is rotatably connected to one end of the first arm body 23121, and the other end of the connecting rod 23122 is rotatably connected to one end of the second arm body 23123. The other ends of the first arm body 23121 and the second arm body 23123 are pressed against the frame 120 of the cleaning device 100 to lift the roller brush bracket 210.

[0102] and Figures 6 to 15The lifting mechanism 231 is different, please refer to Figure 23 to Figure 25 In another embodiment of the cleaning brush 200 of the utility model, the lifting mechanism 231 includes a pulley lifting assembly 231'. As long as the roller brush bracket 210 can be lifted, the structural form of the pulley lifting assembly 231' is not limited, and it can be a fixed pulley group or a combination of a movable pulley and a fixed pulley. The fixed end of the pulley lifting assembly 231' is installed on the cleaning device 100, and the lifting end of the pulley lifting assembly 231' is connected to the roller brush bracket 210 through a rope connecting portion 2314'. It should be noted that the lifting end of the pulley lifting assembly 231' is a corresponding structure that acts on the roller brush bracket 210 to lift the roller brush bracket 210, such as the end of the rope 2313' or the movable pulley hung on the rope 2313', and the fixed end of the pulley lifting assembly 231' is a corresponding structure that acts as a reaction force to resist the lifting force in contrast to the lifting end, such as a fixed pulley in the fixed pulley group 2312' and / or a rope 2313' driving device.

[0103] Although the pulley lifting assembly 231' may also be powered by a drive device independent of the cleaning brush 200, see Fig.24 and Fig.25 In an embodiment of the cleaning brush 200 of the utility model, the pulley lifting assembly 231' includes: a third driving device 2311', a rope 2313' and a pulley block 2312'. The third driving device 2311' is installed on the frame 120 of the cleaning device 100, and the pulley block 2312' includes two fixed pulleys, which are rotatably installed on the frame 120 of the cleaning device 100. One end of the rope 2313' is fixed to the rotating shaft of the third driving device 2311', and the other end of the rope 2313' is used as a lifting end to pass through the two pulleys in sequence and be fixedly connected to the roller brush bracket 210. It should be noted that in other embodiments, the pulley block 2312' can also be installed on the frame 120 of the cleaning device 100.

[0104] See also Figure 7 , Figure 12 to Figure 14 Specifically, the roller brush bracket 210 is provided with a connection part that can be movably connected with the cleaning device 100, and the connection part includes a parallelogram 220 and a movable clamping part 211. The parallelogram 220 and the movable clamping part 211 are respectively located on the roller brush bracket 210 on both sides of the arrangement direction of the first roller brush body 280 and the second roller brush body 290 (i.e., the front and rear sides of the roller brush). The parallelogram 220 is provided with a detachable connection end 221 that can be detachably connected with the frame 120 of the cleaning device 100. When in use, the detachable connection end 221 is connected to the frame 120, and the connection method includes but is not limited to bolt connection. The roller brush bracket 210 is movably connected to the cleaning device 100 through the movement of the movable clamping part 211 and the extension and contraction of the parallelogram structure.

[0105] In the present invention, the movable engaging portion 211 can be any suitable structure type that can engage with the corresponding structure on the cleaning device 100 to achieve sliding limit. Figure 7 and Fig.14 In an embodiment of the cleaning brush 200 of the present invention, a first card slot (not shown) is provided on the cleaning device 100, and the movable card connection portion 211 includes a first card platform 2111 provided on the roller brush bracket 210 and corresponding to the first card slot. The first card platform 2111 is slidably mounted in the corresponding first card slot and slides along the first card slot during lifting or rotation, thereby limiting the movement or rotation of the roller brush bracket 210.

[0106] and Figure 7 The cleaning brush 200 is different, please refer to Fig. 22 In another embodiment of the cleaning brush 200 of the present invention, a connecting portion that can be movably connected to the cleaning device 100 is also provided on the roller brush bracket 210, and the connecting portion includes a rope connecting portion 2314" that can be detachably connected to the rope 2313' and a rotating connecting portion 216 that can be rotatably connected to the cleaning device 100. The rotating connecting portion 216 is rotatably connected to the roller brush bracket 210 and is located in the arrangement direction of the first roller brush body 280 and the second roller brush body 290 (i.e. Fig. 22 The rope connecting portion 2314" is also located on the roller brush bracket 210 and on the other side of the arrangement direction of the first roller brush body 280 and the second roller brush body 290. In this way, the roller brush bracket 210 can be lifted by the rope connecting portion 2314", so that the roller brush bracket 210 drives the first roller brush body 280 and the second roller brush body 290 to rotate upward around the rotating connecting portion 216, thereby achieving the isolation of the first roller brush body 280 and the second roller brush body 290 from the surface to be cleaned.

[0107] See also Fig. 22 In an embodiment of the cleaning brush 200 of the present invention, the outer periphery of the first roller brush body 280 is coated with a hydrophobic layer 282. The outer periphery of the second roller brush body 290 is coated with a hydrophilic layer 291. And the second roller brush body 290 is arranged close to the rope connecting portion 2314". This arrangement allows the second roller brush body 290 with the hydrophilic layer 291 to have a higher position and be isolated from the air of the surface to be cleaned when pulled upward, and the first roller brush body 280 with the hydrophobic layer 282 to have a lower position and be able to contact the surface to be cleaned, thereby performing a dry second cleaning mode.

[0108] See also Fig.21In another embodiment of the cleaning brush 200 of the present invention, the outer periphery of the first roller brush body 280 and the second roller brush body 290 are coated with a hydrophobic layer 282. In the process of switching from the first cleaning operation to the second cleaning operation, the lifting mechanism 231 lifts the first roller brush body 280 and the second roller brush body 290 and performs a drying process, such as quick spinning, wind drying or drying, and drops them onto the surface to be cleaned after the drying process, thereby performing the second cleaning operation in a dry state.

[0109] See also Fig. 9 In an embodiment of the cleaning brush 200 of the utility model, the cleaning brush 200 further includes a spray assembly 212, which is installed in the roller brush bracket 210 and located at the top of the roller brush installation cavity 219. The spray assembly 212 sprays clean water to the first roller brush body 280 and / or the second roller brush body 290 to perform the wet first cleaning mode. It should be noted that the cleaning brush 200 of the utility model may not include the spray assembly 212, but spraying is performed by the spray assembly on the cleaning device 100 or other separately equipped spray assemblies, and no matter where the spray assembly is set, the spray assembly 212 should be closed in the dry second cleaning mode.

[0110] See also Fig. 20 and Fig.21 In the embodiment of the cleaning brush 200 of the utility model, a rubber strip 250 is provided on the roller brush bracket 210 at the rear side along the travel direction of the cleaning brush 200. The rubber strip 250 can scrape and clean the water stains on the surface to be cleaned, making the surface to be cleaned easier to dry. On the other hand, the rubber strip 250 also increases the negative pressure space to improve the cleaning effect. A sealing strip 201 is provided on the roller brush bracket 210 at the front side along the travel direction of the cleaning brush 200. The sealing strip 201 can improve the vacuum degree in the roller brush installation cavity 219.

[0111] The present invention also provides a cleaning system, which includes any of the above cleaning brushes 200. It should be noted that the cleaning system may also include components other than the cleaning brush 200 of the present invention, such as energy systems, negative pressure suction systems, sewage tanks, and clean water tanks, which are conventional components of existing cleaning systems and are not described in detail.

[0112] An isolation mechanism is provided on the cleaning brush of the utility model. In the first state, the isolation mechanism makes the roller brush contact with the surface to be cleaned to perform the first cleaning operation in a wet state. In the second state, the isolation mechanism isolates the roller brush from the surface to be cleaned to perform the second cleaning operation in a dry state or to perform the second cleaning operation in a dry state after drying the corresponding roller brush, thereby improving the technical problem that the existing cleaning brush has poor compatibility with dry cleaning and wet cleaning. Therefore, the utility model effectively overcomes some practical problems in the prior art and has a high utilization value and use significance. The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model.
