[0056] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0057] Reference is made below to Figures 1-9 A middle-sweeping cover plate, a middle-sweeping structure, and a cleaning device 10 according to embodiments of the present application are described.

[0058] Embodiments of the present application provide a middle-sweeping cover plate, as Figures 1-7 shown, the middle-sweeping cover plate includes a frame 200 and a shielding piece 230.

[0059] As shown in Figures 1-7 , the frame 200 as a whole can be a rectangular structure, or a circular structure, a trapezoidal structure, or other shape structures, the frame 200 defines an opening 221 for exposing the roller brush 400, the opening 221 can be a rectangular structure, or a circular structure, or other shape structures, the opening 221 can be arranged at the middle of the frame 200 as a whole, or can be arranged at other positions of the frame 200.

[0060] As shown in Figure 2 , the length direction of the opening 221 is the x direction, and the width direction of the opening 221 is the y direction.

[0061] As shown in Figures 4-7As shown, the rolling brush 400 can include a rolling brush shaft 410 and brush strips 420 extending from one end of the rolling brush shaft 410 to the other end of the rolling brush shaft 410. The brush strips 420 can include a first section, a second section and a third section arranged in sequence along the length of the opening 221. The first section and the third section extend from the two ends of the rolling brush shaft 410 to the middle of the rolling brush shaft 410, and the second section is arranged between the first section and the third section. The first section and the third section can be linear structures, and the second section can be a V-shaped structure. The distance from each brush strip 420 to the center of the rolling brush shaft 410 is equal, and the brush strip 420 can be perpendicular to the center of the rolling brush shaft 410 or not.

[0062] In some other embodiments, the rolling brush 400 can also include bristles, and the bristles are divided into a plurality of groups. The plurality of groups are distributed around the circumference of the rolling brush 400, and each group of bristles extends from one end of the rolling brush shaft 410 to the other end of the rolling brush shaft 410. Each group of bristles is distributed in a spiral or linear manner around the outer circumference of the rolling brush shaft 410. When the rolling brush 400 includes both the brush strips 420 and the bristles, the brush strips 420 and the bristles can be multiple groups, and the multiple groups of bristles and the multiple groups of brush strips 420 are alternately arranged around the circumference of the rolling brush shaft 410.

[0063] As shown in FIGS. 1, 2 and 3, Figure 1 and Figure 3 The frame 200 has a mounting structure 211 for cooperating with the rolling brush shaft 410. The mounting structure 211 can be a groove at the two ends of the frame 200 in the length direction. The two ends of the rolling brush shaft 410 are supported on the mounting structure 211 through the sheath 430, and the rolling brush shaft 410 can be located in the middle of the opening 221 to expose the brush strips 420 and the bristles. If the area of the opening 221 is large, the rolling brush shaft 410 can also be located at other positions of the opening 221.

[0064] As shown in FIGS. 1, 2 and 3, Figures 1-7 The shielding member 230 is arranged at the end of the opening 221 in the length direction, and at least part of the shielding member 230 is located between the middle of the opening 221 and the mounting structure 211 in the length direction of the opening 221, for stopping foreign matter from entering the mounting structure 211. The shielding member 230 extends from the end of the opening 221 to the middle of the opening 221.

[0065] In actual execution, the rolling brush shaft 410 is rotated relative to the mounting structure 211 to drive the brush strips 420 and the bristles to rotate. In the rotating process of the brush strips 420 and the bristles, the debris on the ground is rolled into the interior. There are usually linear objects such as hair on the ground, which are also rolled into the interior. Since the end of the opening 221 is provided with the shielding member 230, the hair and other linear objects can be prevented from entering the end of the opening 221, i.e., the hair and other linear objects can be prevented from entering between the mounting structure 211 and the rolling brush shaft 410.

[0066] By setting the shielding piece 230 at the end of the opening 221, the linear objects such as hair can be prevented from entering between the mounting structure 211 and the roller brush shaft 410 during the cleaning process, so as to avoid the linear objects from winding around the end of the roller brush shaft 410. It can be understood that if too many linear objects wind around the end of the roller brush shaft 410, the diameter of the end of the roller brush shaft 410 is increased, thereby increasing the friction between the end of the roller brush shaft 410 and the mounting structure 211, the rotation speed of the roller brush shaft 410 is reduced or stopped, which leads to the reduction of the working efficiency of the roller brush 400 and the poor cleaning effect.

[0067] According to the middle scanning cover plate provided in the embodiments of the present application, the linear objects such as hair can be prevented from entering between the mounting structure 211 and the roller brush shaft 410 by setting the shielding piece 230, so as to avoid the rotation speed of the roller brush shaft 410 from being reduced or stopped due to the winding of the linear objects, and help to improve the working efficiency of the roller brush 400 and the cleaning effect.

[0068] In some embodiments, as shown in Figure 1 The frame 200 includes an outer frame 210 and a cover plate 220, the cover plate 220 is floatingly assembled to the outer frame 210, the cover plate 220 defines an opening 221, and the shielding piece 230 is arranged on the cover plate 220.

[0069] As shown in Figure 1 The outer frame 210 can be a rectangular structure, or a circular structure, a trapezoidal structure or other shape structures, the cover plate 220 can be a rectangular structure, or a circular structure or other shape structures, and the shape structures of the outer frame 210 and the cover plate 220 can be the same or different.

[0070] The outer frame 210 is provided with an opening, the cover plate 220 is provided with a mounting shaft at a first side in the width direction of the opening 221, the mounting shaft extends along the length direction of the opening 221, the cover plate 220 is mounted to the opening of the outer frame 210 through the mounting shaft, and the cover plate 220 can swing slightly around the mounting shaft at a second side in the width direction of the opening 221, that is, the cover plate 220 is floatingly assembled to the outer frame 210.

[0071] The cover plate 220 defines the opening 221, and the shielding piece 230 is arranged at the end of the opening 221 in the length direction of the cover plate 220.

[0072] By setting the outer frame 210 and the cover plate 220, the mounting strength of the cover plate 220 can be improved, the outer frame 210 and the cover plate 220 are floatingly assembled, and the cover plate 220 can adapt to the changes of the terrain to some extent, so as to avoid the cover plate 220 from being scratched by the protrusions on the ground.

[0073] In some embodiments, as shown in Figures 1-7As shown, the shielding member 230 is formed integrally with the cover plate 220, or the shielding member 230 is assembled to the cover plate 220.

[0074] The shielding member 230 and the cover plate 220 can be integrally formed by injection molding, which can reduce production cost and improve production efficiency to some extent. The shielding member 230 and the cover plate 220 can also be connected by bonding, threaded connection, buckle connection or other connection methods, and the appropriate connection method can be selected according to the actual situation.

[0075] In some embodiments, as shown in Figures 1-7 As shown, the shielding member 230 includes at least one first shielding part 231, which extends from the end of the length direction of the opening 221 to the middle of the length direction of the opening 221, and is used to stop foreign matter from entering the installation structure 211 from the front of the opening 221 (towards the ground side during operation).

[0076] The first shielding part 231 can be a rectangular structure, a circular structure or other shape structure, and the first shielding part 231 can be a sheet structure, a brush or other structure.

[0077] In actual execution process, when the roller brush 400 cleans the debris on the ground, the roller brush 400 drives the debris to rotate towards the back of the cover plate 220. Since the first shielding part 231 is located at the front of the cover plate 220, i.e. the first shielding part 231 is located at the front of the roller brush shaft 410, the linear objects such as hair can be shielded by the first shielding part 231 and cannot be brought to the back of the cover plate 220 by the roller brush 400.

[0078] Since there are many linear objects such as hair on the ground, by setting the first shielding part 231, many linear objects such as hair can be prevented from entering between the installation structure 211 and the roller brush shaft 410, and the shielding effect of the shielding member 230 is ensured, thereby helping the roller brush 400 to improve the working efficiency.

[0079] In some embodiments, as shown in Figures 1-7 As shown, the first shielding part 231 includes four first shielding parts 231 respectively arranged at the top corners of the opening 221, and the two first shielding parts 231 arranged along the width direction of the opening 221 are spaced apart to form a gap 234.

[0080] As shown in Figures 1-7 As shown, the opening 221 is a rectangular structure, and the four first shielding parts 231 are respectively located at the four top corners of the opening 221. The two first shielding parts 231 arranged along the width direction of the opening 221 are spaced apart, and the gap between the two first shielding parts 231 forms a gap 234. The size of the gap 234 can expose the brush bar 420 and / or the bristle part at the end of the roller brush shaft 410.

[0081] In the present application, the brush strip 420 and the bristles have various designs, which are described below.

[0082] First, the brush strip 420 and the bristles are arranged on the brush shaft 410 of the brush roll 400. The brush strip 420 and the bristles can be alternately and spacedly arranged. In the case where the brush roll 400 includes the brush strip 420 and the bristles, the brush strip 420 is closer to the end of the brush shaft 410 than the bristles; or the bristles are closer to the end of the brush shaft 410 than the brush strip 410; or the bristles and the brush strip 420 are flush.

[0083] Second, the brush strip 420 is arranged on the brush shaft 410 of the brush roll 400, and the bristles are not arranged. The brush strip 420 can be multiple, and the multiple brush strips 420 are spacedly arranged along the circumference of the brush shaft 410.

[0084] Third, the bristles are arranged on the brush shaft 410 of the brush roll 400, and the brush strip 420 is not arranged. The bristles can be multiple, and the multiple bristles are spacedly arranged along the circumference of the brush shaft 410.

[0085] In the case where the brush roll 400 is provided with the brush strip 420 and the bristles, the length of the bristles is greater than the length of the brush strip 420. In the cleaning process, the bristles are usually used to bring the linear objects such as hair into the back of the cover plate 220, and the brush strip 420 is used to clean the objects with large volume.

[0086] In actual execution, in the case where the brush roll 400 is provided with the brush strip 420 and the bristles, when the brush roll 400 rotates, the bristles located at the first shielding part 231 interfere with the first shielding part 231. The bristles located at the first shielding part 231 can only clean the ground when the bristles are located at the gap 234 between the two first shielding parts 231, and the cleaning effect is not good. If the bristles located at the first shielding part 231 clean the linear objects such as hair, the first shielding part 231 can scrape the linear objects such as hair on the bristles when the bristles interfere with the first shielding part 231, so as to avoid the linear objects such as hair entering between the mounting structure 211 and the brush shaft 410, and the cleaning effect of the brush strip 420 is not affected in this process.

[0087] By setting the first shielding part 231 at the four top corners of the opening 221, and spacing the two first shielding parts 231 along the width direction of the opening 221 to form the gap 234, the linear objects such as hair can be prevented from entering between the mounting structure 211 and the brush shaft 410 without affecting the cleaning range and cleaning effect of the brush strip 420.

[0088] It should be noted that the inside of the shielding piece 230 can be provided with bristles and brush strips 420; or can not be provided with bristles and brush strips 420; or can be provided with bristles and not provided with brush strips 420; or can be provided with brush strips 420 and not provided with bristles.

[0089] In some embodiments, the first shielding part 231 includes two first shielding parts 231 respectively arranged at the two ends of the length direction of the opening 221, and the first shielding part 231 extends from one end to the other end of the width direction of the opening 221.

[0090] The two first shielding parts 231 are respectively located at the two ends of the length direction of the opening 221, and the first shielding part 231 completely shields the end of the roller brush shaft 410 located in the opening 221, that is, from the front of the cover plate 220, the end of the roller brush shaft 410 located in the opening 221 cannot be seen.

[0091] By setting the first shielding part 231 to extend from one end to the other end of the width direction of the opening 221, the shielding effect of the first shielding part 231 can be improved, and the anti-winding effect of the roller brush 400 can be further improved.

[0092] In some embodiments, as shown in Figure 4 , the length of the opening 221 is W1, the length of the first shielding part 231 along the length direction of the opening 221 is W2, and in the case that the roller brush 400 is provided with brush strips 420, the distance from the end of the opening 221 to the brush strips 420 of the roller brush 400 is W3, and in the case that the roller brush 400 is provided with bristles and not provided with brush strips 420, the distance from the end of the opening 221 to the bristles of the roller brush 400 is W3.

[0093] W3≤W2≤0.125W1 is satisfied.

[0094] As shown in Figures 4-6 , in the case that the roller brush 400 is provided with brush strips 420 and not provided with bristles, the distance from the end of the opening 221 to the brush strips 420 of the roller brush 400 is W3.

[0095] In the case that the roller brush 400 is provided with bristles and not provided with brush strips 420, the distance from the end of the opening 221 to the bristles of the roller brush 400 is W3.

[0096] In the case that the roller brush 400 is provided with brush strips 420 and bristles, and the brush strips 420 are closer to the end of the roller brush shaft 410 than the bristles, the distance from the end of the opening 221 to the brush strips 420 of the roller brush 400 is W3.

[0097] In the case that the roller brush 400 is provided with brush strips 420 and bristles, and the bristles are closer to the end of the roller brush shaft 410 than the brush strips 420, the distance from the end of the opening 221 to the brush strips 420 of the roller brush 400 is W3.

[0098] When the brush strip 420 and the bristles are arranged on the brush roll 400 and the positions of the brush strip 420 and the bristles are flush, the distance from the end of the opening to the brush strip 420 of the brush roll 400 is W3.

[0099] For example, the length W2 of the first shielding portion 231 along the length direction of the opening 221 is 10 mm, and the length W1 of the opening 221 is 160 mm, and in this case, W2 = 0.0625W1.

[0100] The length W2 of the first shielding portion 231 along the length direction of the opening 221 is greater than the distance W3 from the end of the opening 221 to the brush strip 420 of the brush roll 400, or greater than the distance W3 from the end of the opening 221 to the bristles of the brush roll 400, so that the first shielding portion 231 can shield the end of the brush roll 400. The length W2 of the first shielding portion 231 along the length direction of the opening 221 is less than 0.125W3, so that the shielding effect of the first shielding portion 231 is ensured, and the influence on the cleaning range and cleaning effect of the brush roll 400 is reduced.

[0101] It should be noted that the range of the length of the first shielding portion 231 along the length direction of the opening 221 can be set as needed, and the width of the first shielding portion 231 can be greater than or equal to 0, for example, the width of the first shielding portion 231 is 11 mm.

[0102] In some embodiments, as shown in Figures 1-7 The shielding member 230 includes a second shielding portion 232, which protrudes from the edge of the length direction of the opening 221 towards the brush roll 400, and is used to stop foreign matter from entering the mounting structure 211 from the middle of the length direction.

[0103] As shown in Figures 1-7 The second shielding portion 232 is located between the mounting structure 211 and the middle of the brush roll 400, and the second shielding portion 232 protrudes from the edge of the length direction of the opening 221 towards the brush roll 400.

[0104] In actual execution, the part of the brush roll 400 except the end can normally clean foreign matter. Since the brush roll 400 is always in rotation when working, linear objects such as hair and fur are easy to wrap around the brush roll 400 and rotate with the brush roll 400. The linear objects such as hair and fur may move along the line direction of the brush roll shaft 410 during rotation. When the linear objects such as hair and fur move to the end of the brush roll shaft 410 along the line direction of the brush roll shaft 410, they are stopped by the second shielding portion 232, and the linear objects such as hair and fur cannot enter between the mounting structure 211 and the end of the brush roll shaft 410 through the second shielding portion 232.

[0105] Through the setting of the second shielding part 232, foreign matters located in the middle part of the rolling brush 400 can be prevented from causing the rolling brush 400 to be stuck when the rolling brush 400 rotates to the end part of the rolling brush 400, and the working efficiency of the rolling brush 400 is further improved.

[0106] It should be noted that the shielding part 230 can include only the first shielding part 231, only the second shielding part 232, or both the first shielding part 231 and the second shielding part 232; in the case where the shielding part 230 includes only the second shielding part 232, the width of the first shielding part 231 is 0.

[0107] In some embodiments, as shown in Figs. 1 and 2, the first shielding part 231 is arranged on the side of the opening 221 away from the rolling brush 400. Figure 3 and Figure 6 As shown in Figs. 1 and 2, the second shielding part 232 has an arc surface 233, and the center of the arc surface 233 is located on the axis of the rolling brush 400.

[0108] In some embodiments, as shown in Figs. 1 and 2, the second shielding part 232 protrudes from the edge of the opening 221 in the length direction of the opening 221 towards the rolling brush 400, and the second shielding part 232 has the arc surface 233 on the side of the opening 221 close to the rolling brush 400, and the shape of the arc surface 233 is consistent with the rotating path of the brush strip 420.

[0109] Through the setting of the arc surface 233 on the second shielding part 232, the second shielding part 232 can be prevented from interfering with the brush strip 420 during the rotation of the rolling brush 400, so that the brush strip 420 is not damaged. The center of the arc surface 233 is arranged on the axis of the rolling brush 400, so that the effective shielding area is increased while ensuring that the second shielding part 232 does not interfere with the brush strip 420.

[0110] It should be noted that the first shielding part 231 and the second shielding part 232 can be in the form of a comb structure, a rectangular structure, a fence structure, or other shapes, and are not limited in this regard. The first shielding part 231 and the second shielding part 232 can be arranged in the same structure or different structures.

[0111] The first shielding part 231 includes at least one, and the first shielding part 231 can include one or two or more, such as a plurality of rectangular strips or other structures arranged at intervals. The second shielding part 232 includes at least one, and the second shielding part 232 can include one or two or more, such as a plurality of rectangular strips or other structures arranged at intervals.

[0112] In some embodiments, in the case where the rolling brush is provided with a brush strip, the distance between the arc surface and the brush strip of the rolling brush is L1, and 0mm≤L1≤5mm is satisfied.

[0113] In the case where the rolling brush is provided with bristles, the distance between the arc surface and the root of the bristles of the rolling brush is L2, and the length of the bristles is L3, and L2 < L3 is satisfied.

[0114] The arc surface 233 of the two second shielding portions 232 arranged at intervals along the width direction of the opening 221 is an arc on the same circle, and is a concentric circle with the circle of the rotating path of the brush strip 420, the distance from the arc surface 233 to the outer surface of the brush strip 420 of the rolling brush 400 is L1, and 0mm ≤ L1 ≤ 5mm is satisfied. For example, the distance from the rolling brush shaft 410 to the outer surface of the arc surface 233 is 15mm, and the distance from the rolling brush shaft 410 to the arc surface 233 is 17.5mm.

[0115] By limiting the distance from the arc surface 233 to the brush strip 420 of the rolling brush 400 to satisfy 0mm ≤ L1 ≤ 5mm, the shielding area of the second shielding portion 232 can be increased while avoiding interference between the second shielding portion 232 and the brush strip 420, and the shielding effect of the second shielding portion 232 is improved, thereby further improving the anti-winding capability of the rolling brush 400.

[0116] In the case where the rolling brush 400 is provided with bristles, the distance between the arc surface 233 and the root of the bristles of the rolling brush 400 is less than the length of the bristles, for example, L2 = 2 / 3L3, that is, the arc surface 233 is located at a position 1 / 3 away from the end of the rolling brush 400, so that the foreign matter on the bristles can be scraped off by the second shielding portion 232, and the bristles can pass through the second shielding portion 232, thereby avoiding the bristles from being stuck by the second shielding portion 232.

[0117] In some embodiments, as shown in Figures 1-7 In the case where the shielding member 230 includes the first shielding portion 231, the second shielding portion 232 is arranged on the back of the first shielding portion 231.

[0118] In the case where the shielding member 230 includes the first shielding portion 231, the second shielding portion 232 is arranged on the back of the first shielding portion 231 and away from the mounting structure 211, and by cooperation of the first shielding portion 231 and the second shielding portion 232, the foreign matter located on the front of the cover plate 220 and at the middle position of the rolling brush 400 can be prevented from entering between the mounting structure 211 and the end of the rolling brush 400.

[0119] In some embodiments, as shown in Figures 1-7 The second shielding portion 232 is in the form of a sheet and is spaced apart from either end of the length direction of the opening 221.

[0120] The second shielding portion 232 is arranged on the back of the first shielding portion 231 and away from the mounting structure 211, and is spaced apart from either end of the length direction of the opening 221, that is, the second shielding portion 232 and the first shielding portion 231 are in a hollow structure.

[0121] In actual operation, if the roller brush 400 is provided with bristles at the position between the first blocking part 231 and the second blocking part 232, the bristles need to pass through the first blocking part 231 and the second blocking part 232 when the roller brush 400 rotates, and abut against the first blocking part 231 and the second blocking part 232. The bristles can only pass through the first blocking part 231 and the second blocking part 232 smoothly after being bent and deformed.

[0122] By setting the second blocking part 232 as a sheet and spaced apart from any end of the opening 221 in the length direction, the resistance of the first blocking part 231 and the second blocking part 232 to the bristles can be reduced, making it easier for the bristles to pass through.

[0123] In some embodiments, the second shielding portion 232 includes four portions respectively disposed at the top corners adjacent to the opening 221, and two portions 232 disposed along the width direction of the opening 221 are spaced apart.

[0124] like Figures 1-7 As shown, the opening 221 has a rectangular structure, and four second blocking parts 232 are located at the four apex corners of the opening 221. Two adjacent second blocking parts 232 are spaced apart, and the gap between two second blocking parts 232 arranged along the width direction of the opening 221 forms a notch 234. The size of the notch 234 is large enough to expose the brush bar 420 and the bristle portion located at the end of the roller brush shaft 410.

[0125] By setting the second shielding part 232 as four at the top corner of the opening 221, and the two first shielding parts 231 arranged along the width direction of the opening 221 are spaced apart to form a notch 234 to expose the end of the brush strip 420, the brush strip 420 can be cleaned within the maximum range, and without affecting the cleaning range and cleaning effect of the brush strip 420, it can prevent hair, hair and other linear objects from entering between the mounting structure 211 and the roller brush shaft 410.

[0126] In other embodiments, the second shielding portion 232 includes two portions respectively disposed at both ends of the length direction adjacent to the opening, and the second shielding portion 232 extends from one end of the opening 221 to the other end in the width direction.

[0127] The two second shielding parts 232 are located at both ends of the opening 221 along its length, and the second shielding parts 232 respectively shield between the end and the middle of the roller brush shaft 410.

[0128] By setting the second blocking portion 232 to extend from one end to the other in the width direction of the opening 221, the blocking effect of the second blocking portion 232 can be improved, further helping to improve the anti-winding effect of the roller brush 400.

[0129] The embodiment of the present application also provides a middle-sweeping structure, as shown in Figures 4-7 The middle-sweeping structure comprises the rolling brush 400 and the middle-sweeping cover plate according to any one of the above embodiments, and the rolling brush shaft 410 of the rolling brush 400 is rotatably installed on the mounting structure 211.

[0130] According to the middle-sweeping structure provided by the embodiment of the present application, the middle-sweeping cover plate according to any one of the above embodiments is used, so that the linear objects such as hair can be prevented from entering between the mounting structure 211 and the rolling brush shaft 410, the rotation speed of the rolling brush shaft 410 caused by the winding of the linear objects can be avoided, and the working efficiency and cleaning effect of the rolling brush 400 are improved.

[0131] The embodiment of the present application also provides a cleaning device 10, as shown in Figure 8 The cleaning device 10 comprises the middle-sweeping structure according to any one of the above embodiments, and the frame 200 is installed on the casing 100.

[0132] As shown in Figure 8 The cleaning device 10 can be a sweeping robot, a scrubber or other device for cleaning foreign matters. For example, the cleaning device 10 is a sweeping robot, and the frame 200 is installed on the casing 100 of the sweeping robot.

[0133] According to the cleaning device 10 provided by the embodiment of the present application, the middle-sweeping structure according to any one of the above embodiments is used, so that the linear objects such as hair can be prevented from entering between the mounting structure 211 and the rolling brush shaft 410, the rotation speed of the rolling brush shaft 410 caused by the winding of the linear objects can be avoided, and the working efficiency and cleaning effect of the rolling brush 400 are improved.

[0134] The embodiment of the present application also provides a winding-removing mechanism, which comprises the hair processing device arranged on the cleaning base station and the middle-sweeping structure according to any one of the above embodiments, and the hair processing device comprises a blade assembly for cutting the linear objects wound on the rolling brush.

[0135] In some embodiments, as shown in Figure 9 In the case that the first shielding part 231 comprises four first shielding parts respectively arranged at the top corners of the opening 221, the frame 200 is provided with a connecting surface 235 connected between the inner side surface and the lower surface at the end of the length direction of the opening 221, the connecting surface 235 extends downwardly from the inner end connected with the inner side surface to the outer end connected with the lower surface, and the width of the connecting surface 235 along the two ends of the width direction of the opening 221 is not equal.

[0136] The connecting surface 235 is arranged at the side of the gap 234 parallel to the width direction of the opening 221, the width of the connecting surface 235 at the first end along the width direction of the opening 221 is greater than the width at the second end, the side of the connecting surface 235 along the length direction of the opening 221 close to the brush strip 420 is arranged to be inclined upward from the first end to the second end of the connecting surface 235, and the side of the connecting surface 235 along the length direction of the opening 221 away from the brush strip 420 is arranged to be inclined downward from the middle to the two ends, that is, the side of the connecting surface 235 along the length direction of the opening 221 away from the brush strip 420 is formed in a shape similar to an arc surface.

[0137] The base station of the cleaning device 10 is provided with a hair processing device 300, the hair processing device 300 comprises a blade assembly 330, a driving mechanism 310 and a mounting assembly 320, the blade assembly 330 and the driving mechanism 310 are both mounted on the mounting assembly 320, the driving mechanism 310 comprises a driving motor 311 and an output shaft 312, the blade assembly 330 is driven by the driving mechanism 310 to cut linear objects such as hair, the blade assembly 330 is pressed on the mounting assembly 320 by a pressing mechanism 340, and the pressing mechanism 340 comprises a pressing cap 341 and an elastic member 342.

[0138] The blade assembly 330 can comprise a first blade 331 and a second blade 332.

[0139] The first blade 331 can be connected with the mounting assembly 320, and the first blade 331 does not rotate with the rotation of the output shaft 312.

[0140] In the embodiment, the first blade 331 can be sleeved outside the output shaft 312 and arranged in a spaced manner with the output shaft 312, and the first blade 331 can be fixedly mounted on the mounting assembly 320. In an example, the first blade 331 can be provided with through holes for bolts or screws to pass through on both sides of the position where the output shaft 312 passes through, and the first blade 331 is fixedly mounted on the mounting assembly 320 by the cooperation of the threaded members passing through the through holes and the mounting assembly 320.

[0141] In another embodiment, the first blade 331 can also be arranged on the upper side of the output shaft 312, and the first blade 331 can be fixedly mounted on the mounting assembly 320.

[0142] The second blade 332 is power-coupled with the output shaft 312 and arranged on the side of the first blade 331 away from the mounting assembly 320. The rotation of the second blade 332 is driven by the rotation of the output shaft 312, and the second blade 332 is arranged on the side of the first blade 331 away from the mounting assembly 320, so that the rotation of the second blade 332 does not affect the abutment of the first blade 331 and the mounting assembly 320. The cutting or shearing effect is realized by the cooperation of the rotation of the second blade 332 and the first blade 331, so as to cut and shred the hair, facilitating the recycling of the cleaning device or the base station.

[0143] In the embodiment, the first blade 331 and the second blade 332 each include a tooth edge part, and the two tooth edge parts are mirror-imaged to form a scissors-like structure to generate a shearing force to cut the hair. Since the first blade 331 is fixedly connected to the mounting assembly 320, when the second blade 332 rotates relative to the first blade 331, the hair on the roller brush 400 of the cleaning device is pulled to the first blade 331 by the second blade 332, thereby forming a shearing force to cut the hair, so as to solve the problem that the hair is soft and entangled on the roller brush 400, the bristles and the brush strip 420 on the roller brush 400 are difficult to fix or support the hair, and the hair cannot be cut by the blade directly to cause poor cleaning effect. At the same time, when the second blade 332 does not rotate to the first blade 331, the second blade 332 cannot form a shearing force with the first blade 331, so as to avoid that the blade assembly 330 hurts the roller brush 400 when cutting the hair, and improve the user experience.

[0144] The blade assembly 330 moves along the length direction of the opening 221 and cuts the linear objects such as the hair. The second blade 332 is in an arc structure on both sides of the length direction of the opening 221, and is adapted to the shape of the connecting surface 235. When the second blade 332 moves to the connecting surface 235, the linear objects such as the hair at the end of the roller brush 400 can be cut.

[0145] By providing the connecting surface 235 between the inner side surface and the lower surface at the end of the length direction of the opening 221, the connecting surface 235 extends downwardly from the inner end connected to the inner side surface to the outer end connected to the lower surface, and the width of the connecting surface 235 along the two ends of the width direction of the opening 221 is not equal, so as to enable the blade assembly 330 of the base station to cut the linear objects such as the hair at the two ends of the roller brush 400 to the maximum extent, and further avoid that the linear objects such as the hair at the two ends of the roller brush 400 enter between the mounting structure 211 and the end of the roller brush 400.

[0146] According to the entanglement removing mechanism provided in the embodiment, the linear objects such as the hair are controlled at the position except the end of the roller brush 400 by the middle sweeping structure, and the linear objects such as the hair entangled at the position except the end of the roller brush 400 are cut by the hair processing device provided in the cleaning base station, so as to further improve the anti-entanglement effect of the roller brush 400.
