Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning devices, in particular to a rolling brush cover assembly, a cleaning module and a cleaning device. BACKGROUND

[0002] A cleaning device (such as a sweeper or a scrubber) is provided with a middle sweeper for sweeping garbage on the ground. By controlling the rotation of the rolling brush of the middle sweeper and making the scraping strip close to the floor, hair, thread and other linear objects and other garbage (such as paper scraps, dust, packaging bags, etc.) on the floor can be swept. The rotating rolling brush can drive the linear objects and garbage to move towards the dust collection port of the cleaning device to be collected into the dust box. The cover plate structure provided with the scraping strip mainly includes a fixed cover plate and a floating cover plate. During the floating process of the floating cover plate, the gap between the floating cover plate and the end of the rolling brush will increase. The linear objects wound on the rolling brush are easy to enter the end of the rolling brush from the gap between the floating cover plate and the end of the rolling brush, and are easy to wrap around the end of the rolling brush, thereby increasing the risk of rotation of the rolling brush and reducing the service life of the middle sweeper mechanism and the sweeping effect and dust collection effect.

DETAILED DESCRIPTION ​​​

[0103] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0104] It should be noted that the terms used herein are only intended to describe specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form, unless the context clearly indicates otherwise, and it should also be understood that, when the terms "comprise" and / or "include" are used in the specification, there is a presence of the features, steps, operations, devices, components and / or combinations thereof.

In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0106] To solve the problem that the linear object wound on the roller brush easily enters the end of the roller brush and interferes with the structure of the end rotating shaft of the roller brush, the inventor of the present application has found, after in-depth research, that at present, the roller brush cover assembly for installing the roller brush and the scraping strip 22 to the bottom of the cleaning device includes a fixed cover plate and a floating cover plate. The floating cover plate is usually connected with the scraping strip 22 to enable the scraping strip to assist the roller brush in cleaning work. Since the floating cover plate is located in the opening of the middle region of the fixed cover plate, after the roller brush is installed in the opening of the fixed cover plate, the gap between the floating cover plate and the end of the roller brush will increase after the floating cover plate floats relative to the fixed cover plate. After the gap increases, the linear object and other garbage are easily to enter the end of the roller brush from the gap between the floating cover plate and the end of the roller brush, thereby being wound and gathered in the end of the roller brush, increasing the risk of rotation of the roller brush. The service life of the roller brush cover assembly and the cleaning effect and dust collection effect of the cleaning device using the roller brush cover assembly are reduced.

[0107] In view of the above problems, the first embodiment of the present application provides a roller brush cover assembly, please see Figures 1 to 15 The roller brush cover assembly includes a frame 11, a matching piece 112 and a scraping component. As Figure 2As shown, the frame 11 is provided with an opening 111. The scraping component includes a bracket 12 and a scraping strip 22. The bracket 12 is rotationally connected with the frame 11 and is arranged around the opening 111. The scraping strip 22 is connected with the bracket 12 and is located at one side of the opening 111 in the width direction and is configured to abut against the surface to be cleaned, so that the scraping strip 22 can scrape and push the garbage, linear objects and sewage stains on the surface to be cleaned to the roller brush body 212, and then the garbage, linear objects and sewage stains are cleaned to the dust box of the cleaning equipment by the roller brush body 212.

[0108] In addition, the scraping strip 22 can push the bracket 12 to rotate relative to the frame 11 under the action of an external force. The external force acting on the scraping strip 22 is mainly affected by the flatness and shape of the surface to be cleaned. For example, when the scraping strip 22 encounters a convex position of the surface to be cleaned, the scraping strip 22 is pushed to rotate the bracket 12 by a force away from the convex position. When the scraping strip 22 moves from the convex position to a flat position, the external force acting on the scraping strip 22 is removed and returns to the state of abutting against the flat position. The bracket 12 can adaptively adjust its position relative to the frame 11 according to the shape of the surface to be cleaned, so as to avoid the bracket 12 being scratched by the protrusions on the surface to be cleaned and enable the scraping strip 22 to always abut against the surface to be cleaned. The scraping strip 22 is connected with the bracket 12 and is specifically located at one side of the opening 111 in the second direction. The second direction is the width direction of the opening 111, i.e. Figure 2 The frame 11 can have a rectangular structure, or a circular structure, a trapezoidal structure or other shapes, which can be determined according to actual needs and is not limited in the embodiment.

[0109] The cooperating part 112 is arranged on the frame 11 and is located at least one side of the opening 111 in the first direction. The cooperating part 112 separates the roller brush body 212 of the cleaning module from the bracket 12. The opening 111 can be a rectangular opening, a square opening, an oval opening, etc. according to the size and number of the roller brush body 212, and the shape of the opening 111 is not limited in the embodiment.

[0110] The matching piece 112 is used to prevent the rolling brush body 212 of the cleaning module from winding the linear object at least at one end of the two ends. During the rotation of the support 12 relative to the frame 11, no matter how the gap between the support 12 and the frame 11 changes, since the matching piece 112 is stationary relative to the frame 11, the matching piece 112 can isolate the rolling brush body 212 and the support 12, and the adjacent arrangement relationship of the components of the rolling brush cover structure in the height direction or the horizontal first direction changes from the original rolling brush body 212-floatable support 12-frame 11 to rolling brush body 212-stationary matching piece 112-floatable support 12-frame 11. Therefore, the gap between the rolling brush body 212 and the matching piece 112 remains unchanged, and the gap between the rolling brush body 212 and the matching piece 112 does not increase with the rotation (or floating) of the support 12, so that the linear object swept by the rolling brush body 212 is less likely to enter between the end of the rolling brush body 212 and the matching piece 112, and other garbage and linear objects are moved away from the end of the rolling brush body 212 (such as to the middle region of the rolling brush body 212) with the rotation of the rolling brush body 212, and finally the garbage and linear objects are recycled by the dust box of the cleaning device. Therefore, no matter whether the support 12 rotates relative to the frame 11, the gap between the end of at least one end of the rolling brush body 212 and the matching piece 112 does not increase, reducing the risk of linear objects winding on the rolling brush body 212 entering the end of the rolling brush body 212 from the gap between the rolling brush body 212 and the matching piece 112. Thus, the linear object can be prevented from entering the end of the rolling brush body 212 and the rotating member 211 connected to the driving mechanism, avoiding winding of the rotating member 211 and preventing the motor of the driving mechanism from being blocked, thereby improving the reliability and service life of the driving mechanism.

[0111] The matching piece 112 in the embodiment can be a separate accessory connected to the frame 11, and the matching piece 112 can be connected to the frame 11 by a predetermined connection mode, including but not limited to at least one of clamping, welding, mortise and tenon connection, etc. The matching piece 112 can also be an integrally formed structure with the frame 11, and after selecting the plate material of the frame 11, the frame 11 and the matching piece 112 can be processed on the plate material, or the matching piece 112 and the frame 11 can be integrally formed by injection molding, which is convenient to process and reduces the assembly difficulty between the frame 11 and the matching piece 112.

[0112] The rolling brush component 21 in the embodiment comprises a rolling brush body 212, which is installed in the opening 111 to enable the rolling brush body 212 to rotate to clean a surface to be cleaned (such as a floor, a table top, a wall, etc.) in the opening 111. The rolling brush component 21 further comprises a rotating piece 211, which is arranged on at least one of the matching piece 112 and the frame 11 and connected with the rolling brush body 212 to enable the rolling brush body 212 to be installed in the opening 111. When the cleaning device comprises a bottom shell 50 provided with a dust suction port 51, the scraping strip 22 can scrape garbage and linear objects on the surface to be cleaned and push them towards the rolling brush body 212, so that the garbage and linear objects can move towards the dust suction port 51 along with the rotation of the rolling brush body 212. The dust suction port 51 is in communication with a dust box in the cleaning device, and the dust box can collect the garbage and linear objects in a storage space thereof under the negative pressure generated by an air suction member (such as a vacuum pump, a fan, etc.).

[0113] Secondly, the rolling brush component 21 in the embodiment further comprises the rotating piece 211, which is arranged on the matching piece 112 and connected with the rolling brush body 212. At least one end of the rolling brush body 212 relative to two ends thereof is a fixed end 2120, which is an end face of the rolling brush body 212 relative to two ends thereof. The fixed end 2120 is at least used to be connected with a driving mechanism of the cleaning device. When the rolling brush body 212 comprises a rolling cylinder 2121, a first brush strip 2122 and a second brush strip 2123, the fixed end 2120 is an end face of at least one end of the rolling cylinder 2121 relative to two ends thereof and end positions of the first brush strip 2122 and the second brush strip 2123 relative to an end face of the rolling cylinder 2121 (the end positions can be flush with or not flush with the end face of the rolling cylinder 2121). When a blocking ring 213 is arranged at an end of the rolling brush body 212, the fixed end 2120 can also be an end face of the blocking ring 213 away from the first brush strip 2122 and the second brush strip 2123. The fixed end 2120 can be connected with the driving mechanism of the cleaning device through the rotating piece 211 located at the matching piece 112. In a third direction (i.e. a height direction of the frame 11, an arrow z indicates a direction), a projection outer contour of the bracket 12 is misaligned with a projection outer contour of the rotating piece 211. That is, the projection outer contour of the rotating piece 211 is tangent to or has a certain gap with the projection outer contour of the bracket 12. Whether the bracket 12 floats relative to the frame 11 or not, the bracket 12 will not interfere with the rotating piece 211, improving the reliability of the rotating piece 211 in driving the rolling brush body 212 to rotate under the driving of the driving mechanism, further reducing the risk of the rolling brush body 212 being stopped, and ensuring that the rolling brush body 212 will not be stopped due to the interference between the rotating piece 211 and the bracket 12. Figure 2

[0114] ​After the rolling brush cover assembly is installed at the bottom of the cleaning device, the fixed end 2120 of the rolling brush body 212 is directly connected with the driving mechanism in the cleaning device or connected with the driving mechanism through the rotating piece 211, so that the driving mechanism can drive the rotating piece 211 to rotate the rolling brush body 212. The driving mechanism can specifically include a motor and a gear box and the like structure, the motor is installed in the installation shell of the cleaning device and is in transmission connection with the gear box, the output shaft of the gear box is connected with the rotating piece 211, the motor drives the gear box to rotate the rotating piece 211, and the rotating piece 211 can also drive the rolling brush body 212 to rotate. Since the support 12 will not interfere with the rotating rotating piece 211, the rotation reliability of the rotating piece 211 is improved. At the same time, the gap between the fixed end 2120 of at least one end of the rolling brush body 212 and the matching piece 112 will not be increased, and the linear object wound on the rolling brush body 212 is not easy to enter the end of the rolling brush body 212 from the gap between the rolling brush body 212 and the matching piece 112. Garbage and linear objects will move in the direction of the dust suction port 51 along with the rotation of the rolling brush body 212, avoiding the winding of the linear object between the end of the rolling brush body 212 and the driving mechanism or between the rotating piece 211, reducing the risk of the rolling brush body 212 to stop rotating or the rolling brush body 212 to rotate at a low speed, reducing the risk of the rolling brush body 212 to stop rotating and making the rolling brush body 212 to rotate stably and reliably, improving the structural stability and cleaning effect of the rolling brush cover assembly.

[0115] It can be seen that, in the embodiment, the roller brush cover assembly includes the frame 11, the matching piece 112, and the scraping assembly. The frame 11 is provided with an opening for mounting and exposing the roller brush body 212, so that the roller brush body 212 can be in contact with the surface to be cleaned to perform cleaning work. The support 12 of the scraping assembly is rotationally connected with the frame 11, and the scraping strip 22 is connected with the support 12. The scraping strip 22 assists the roller brush body 212 in performing the cleaning work. The matching piece 112 is located on at least one side of the opening 111 along the first direction. The matching piece 112 can isolate at least one end of the roller brush body 212 mounted in the opening along the first direction from the support 12. The isolation can be transverse isolation along the first direction and / or longitudinal isolation along the third direction. The matching piece 112 is at least used to prevent the roller brush body 212 from winding the linear object at least at one end. Thus, during the process in which the scraping strip 22 pushes the support 12 to rotate relative to the frame 11, whether the gap between the matching piece 112 and / or the frame 11 and the support 12 increases or decreases, the gap between the end of at least one end of the roller brush body 212 and the matching piece 112 as a fixed piece always remains unchanged. The linear object cleaned by the roller brush body 212 is not easy to enter between the end of the roller brush body 212 and the matching piece 112. Other garbage and linear objects will move away from the end of the roller brush body 212 along with the rotation of the roller brush body 212. Finally, the garbage and linear objects will be recycled by the dust box of the cleaning device, or processed by other ways such as cutting by the blade, cleaning by the comb 23, etc. The effect of no linear object winding at the end of the roller brush body 212 is achieved, the risk of rotation stop of the roller brush part 21 is reduced or even the phenomenon of rotation stop of the roller brush part 21 is completely avoided, the maintenance frequency of the roller brush cover assembly is reduced, the service life of the roller brush cover assembly is improved, and the cleaning effect and dust collection effect of the cleaning device using the roller brush cover assembly are improved.

[0116] Along the first direction, the outer edge of at least one side of the support 12 close to the opening 111 does not exceed the outer edge of the side of the matching piece 112 close to the opening 111, so that at least one side of the support 12 along the first direction does not coincide with the opening 111, and the support 12 and the roller brush body 212 mounted in the opening 111 are isolated in the height direction (i.e., the third direction) and the first direction by the matching piece 112.

[0117] For example, along the first direction, the matching piece 112 can be at least partially located between the opening 111 and the support 12. Thus, the matching piece 112 can be located between the roller brush body 212 and the support 12 in the manner as shown in Figure 3 . In combination with Figure 22 and Figure 24It can be known that the matching part 112 can also be located between the rolling brush body 212 and the support 12, and the specific form is not uniquely limited in the embodiment, and only the support 12 can be separated from the rolling brush body 212 which can rotate (or float) relative to the frame 11.

[0118] As shown in Figures 2 to 3 In the embodiment, the opposite sides of the opening 111 are provided with the matching part 112 along the first direction. At this time, the rolling brush body 212 in the embodiment can be the first rolling brush structure or the second rolling brush structure. The first rolling brush structure is the rolling brush structure with one end of the opposite ends as the fixed end 2120, that is, the first rolling brush structure is the single cantilever rolling brush structure with one end as the fixed end 2120 connected with the driving mechanism, and the matching part 112 can be located between the fixed end 2120 of the first rolling brush structure and the support 12, so that the winding object is not easy to enter the fixed end 2120 of the first rolling brush structure to affect the rotation of the first rolling brush structure. When the rolling brush body 212 is the second rolling brush structure, the opposite ends of the second rolling brush structure along the first direction are both the fixed end 2120, that is, the fixed ends 2120 of the opposite ends of the second rolling brush structure are both connected with the driving mechanism through the rotating part 211. The rolling brush body 212 can also be two single cantilever first rolling brush structures, and the two first rolling brush structures are coaxially arranged, and the fixed ends 2120 of the two first rolling brush structures away from each other along the first direction can be respectively supported on the matching part 112 through the corresponding rotating part 211 and connected with the driving mechanism. Of course, the rolling brush body 212 in the embodiment can also include three and more than three first rolling brush structures and / or second rolling brush structures, no matter how many rolling brush structure monomers the rolling brush body 212 has, all the rolling brush structures are located in the opening 111, and therefore, in order to adapt to different cleaning environments and user needs, the number of monomers of the rolling brush body 212 is not uniquely limited in the embodiment.

[0119] As shown in Figures 2 to 3 and Figure 11 The support 12 in the embodiment includes the frame plate 121, and the frame plate 121 defines the first opening 1210. The frame plate 121 is arranged on the frame 11 and covers the first opening 1210 and the opening 111 in communication, and in combination with Figure 3 and Figures 7 to 8It can be known that the rolling brush body 212 is exposed to the communication area of the first opening 1210 and the opening 111. In the first direction, the inner wall surfaces on the opposite sides of the first opening 1210 are located on the side of the fitting part 112 away from the opening 111, so that the parts of the frame plate 121 on the opposite sides of the first opening 1210 are located on the side of the fitting part 112 away from the rolling brush body 212 in the first direction, so that the gap between the end portions of the opposite ends of the rolling brush body 212 and the fitting part 112 remains unchanged, the linear objects cleaned by the rolling brush body 212 are not easy to enter between the end portions of the rolling brush body 212 and the fitting part 112, and the effect that the end portions of the opposite ends of the rolling brush body 212 are not wound by the linear objects is realized, and the risk of rotation stop of the rolling brush part 21 is further reduced or even the phenomenon of rotation stop of the rolling brush part is completely avoided.

[0120] Secondly, since some existing supports 12 will also extrude the rolling brush body 212, and then extrude the linear objects wound on the rolling brush body 212, the linear objects cannot move into the dust box along with the rotation of the rolling brush body 212, and these linear objects are easy to enter the gap between the end portions of the rolling brush body 212 and the supports 12 and the shaft 2111 and wind on the rolling brush end bearing structure, which also increases the risk of rotation stop of the rolling brush. The parts of the frame plate 121 on the opposite sides of the first opening 1210 in the embodiment of the application will not contact the rolling brush body 212, which reduces the extrusion of the frame plate 121 on the first brush strip 2122 and / or the second brush strip 2123 on the rolling brush body 212, ensures that the first brush strip 2122 and the second brush strip 2123 can timely convey the linear objects and other garbage to the dust suction port 51 of the cleaning equipment, and thus the winding risk of the opposite ends of the rolling brush body 212 in the first direction due to extrusion can be reduced. The parts of the frame plate 121 on the opposite sides of the first opening 1210 will not interfere with the operation of the rotating part 211. Whether the rolling brush body 212 includes several rolling brush structure monomers, the linear objects and other garbage are not easy to enter between the opposite ends of the rolling brush body 212 and the fitting part 112, the risk of rotation stop of the rolling brush part 21 is further reduced, and the support 12 can adapt to different types of rolling brush bodies 212.

[0121] In the second direction, at least one side of the frame plate 121 is located between the inner wall surface of the opening 111 and the roller brush body 212 (for example, one side of the frame plate 121 is located between the inner wall surface of the opening 111 and the roller brush body 212, or the opposite two sides of the frame plate 121 are located between the inner wall surface of the opening 111 and the roller brush body 212), and the scraping strip 22 is connected to the side of the frame plate 121 in the second direction, so that the scraping strip 22 can better gather garbage and linear objects to the roller brush body 212. Thus, the first opening 1210 is arranged in the frame plate 121 in the embodiment, which not only makes the opposite two sides of the frame plate 121 in the first direction not interfere with the rotating member 211 and press the roller brush body 212, but also makes the connection structure between the frame plate 121 and the frame 11 more compact and reliable.

[0122] In some embodiments of the application, in order to make the frame plate 121 and the scraping strip 22 adapt to different shapes (such as uneven surfaces, inclined surfaces, arc surfaces, etc.) of the surface to be cleaned, the frame plate 121 is rotationally connected (also referred to as floating connection) to the frame 11. The rotationally connected essence is that the frame plate 121 can float or move a certain distance in the third direction relative to the frame 11. Although this can be achieved by arranging elastic members (such as torsional springs, springs, etc.) between the frame plate 121 and the frame 11, this assembly method is complex and will occupy a large installation space of the cleaning device, which is not conducive to the integration and miniaturization of the cleaning device.

[0123] To this end, as shown in Figure 9 , Figure 24 The clearance 113 is arranged between the cooperating member 112 and the frame 11 in the third direction. The clearance 113 is located on at least one side of the frame 11 in the second direction, and the opposite two sides of the clearance 113 in the second direction are in communication with the opening 111. In the first direction, the opposite two sides of the bracket 12 (for example, the opposite two sides of the frame plate 121) extend into the clearance 113 and can reciprocate in the third direction relative to the frame 11.

[0124] Since the opposite two sides of the bracket 12 (for example, the frame plate 121) are located in the clearance 113, whether the gap between the bracket 12 and the frame 11 and the gap between the bracket 12 and the cooperating member 112 increases or decreases, the gap between the end of at least one end of the roller brush body 212 and the cooperating member 112 remains unchanged. The linear objects swept up by the roller brush body 212 are less likely to enter between the end of the roller brush body 212 and the cooperating member 112. At the same time, it can also ensure that the frame plate 121 does not interfere with the rotating member 211 and reduces the pressure on the roller brush body 212.

[0125] The avoiding space 113 can provide sufficient moving space for the reciprocating movement of the frame plate 121 along the third direction, so that the frame plate 121 and the scraping strip 22 can adapt to different shapes of the surface to be cleaned, avoid damage to the frame plate 121 by the surface to be cleaned, and ensure that the scraping strip 22 can always be in close contact with the surface to be cleaned, thereby improving the scraping effect of the scraping strip 22 on the surface to be cleaned of different terrains. In addition, the avoiding space 113 is arranged in the frame 11, which further improves the structural compactness between the frame plate 121 and the frame 11, and is conducive to reducing the overall volume of the roller brush cover assembly on the basis of ensuring the connection strength between the frame plate 121 and the frame 11, thereby saving the installation space of the cleaning equipment.

[0126] In combination Figure 2 And Figure 9 It can be seen that the avoiding space 113 in some embodiments can be arranged on at least one side of the frame 11 along the third direction. Along the first direction, the isolation part 201 of the matching part 112 can be located between the avoiding space 113 and the opening 111, so that the isolation part 201 can isolate the roller brush body 212 and the frame plate 121. And the opposite sides of the avoiding space 113 along the second direction are in communication with the opening 111. Along the first direction, the opposite sides of the frame plate 121 extend to the avoiding space 113 and can reciprocate along the third direction relative to the frame 11. The frame plate 121 in the present embodiment can be a rectangular frame plate 121, a circular frame plate 121, a rhombic frame plate 121 or a frame plate 121 structure of other shapes. The shape of the frame plate 121 can be the same as or different from the shape of the frame 11.

[0127] In the present embodiment, as shown in Figure 9 And Figure 24 The matching part 112 includes an isolation part 201 and a connecting part 202. The isolation part 201 is located between the avoiding space 113 and the opening 111, so that the matching part 112 can isolate the roller brush body 212 and the support 12 through the isolation part 201 thereof, and ensure that the gap between the roller brush body 212 and the matching part 112 can remain unchanged. The connecting part 202 is connected between the isolation part 201 and the frame 11, so that the matching part 112 can be connected together with the frame 11 through the connecting part 202 thereof. The connecting part 202 and the frame 11 can be integrally formed, or the connecting part 202 can be connected together with the frame 11 by the predetermined connection mode mentioned above, which is not uniquely limited in the present embodiment. The matching part 112 is convenient to process and easy to assemble, and has a compact and reliable overall structure.

[0128] The isolation part 201 can be a block structure as shown in Figure 9 The isolation part 201 can also be a structure such as the convex arc block 011 as shown in Figure 24 And Figure 26 Along the third direction, the bottom surface of the convex arc block 011 is a convex arc shape protruding downward, and the arrangement of the convex arc block 011 can make the overall structure of the roller brush cover module more compact and beautiful.

[0129] In the third direction, the isolation part 201 at least partially protrudes from the lower surface of the bracket 12, so that the isolation part 201 can better separate the bracket 12 and the roller brush body 212, so that the linear object on the roller brush body 212 is less likely to drift to the gap on both sides of the bracket 12 during the rotation of the bracket 12, and the isolation effect is better. When the rotating part 211 of the roller brush part 21 is installed on the second groove 1122 of at least one of the cooperating part 112 and the frame 11 mentioned below, the linear object is less likely to enter the rotating part 211, and the anti-winding effect is better.

[0130] In the third direction (height direction), the bracket 12 is located below the cooperating part 112, wherein, as shown in Figure 30 In the first direction, at least one side of the bracket 12 close to the outer edge of the opening 111 coincides with the outer edge of the side of the cooperating part 112 close to the opening 111, that is, the side of the bracket 12 and the cooperating part 112 close to the opening 111 is flush in the third direction, which can improve the sealing performance of the roller brush cover structure and reduce the risk of garbage being stuck between the cooperating part 112 and the bracket 12. Moreover, the bracket 12 is located below the cooperating part 112 to isolate the roller brush body 212 and the bracket 12 in the height direction, and the adjacent arrangement relationship of the components of the roller brush cover structure in the third direction is changed from the original roller brush body 212-floatable bracket 12-frame 11 to roller brush body 212-static cooperating part 112-floatable bracket 12, so that the linear object is less likely to be wound to the end of the roller brush body 212.

[0131] When the isolation part 201 includes the convex arc block 011, the bracket 12 is provided with a avoiding port 120, which is arranged with the bottom of the convex arc block 011 close to the bracket 12 in the third direction. Thus, while improving the sealing performance between the cooperating part 112 and the bracket 12, the avoiding port 120 can also avoid the protruding bottom of the convex arc block 011, which helps to reduce the overall thickness of the roller brush cover assembly, thereby improving the obstacle-crossing ability of the cleaning equipment and reducing noise (because the bracket 12 is less likely to contact the ground at this time, the noise generated by the friction between the bracket 12 and the ground can be reduced).

[0132] The matching piece 112 is provided with a first groove 61. In the third direction, the first groove 61 is concave. In the first direction, the first groove 61 is located on the side of the matching piece 112 close to the opening 111 and communicates with the opening 111. In this embodiment, the blocking structure 60 can be arranged between the rolling brush body 212 and the matching piece 112. When the blocking structure 60 includes a flexible blocking piece 62, the flexible blocking piece 62 can be arranged at least one end of the rolling brush body 212. In the first direction, at least part of the flexible blocking piece 62 is located in the first groove 61 and is in interference fit with the inner wall surface of the first groove 61. Therefore, during the rotation cleaning of the rolling brush body 212, the flexible blocking piece 62 in interference fit with the inner wall surface of the first groove 61 and the matching piece 112 can better block the linear object, avoiding the linear object drifting in the first direction to the two sides of the support 12.

[0133] In this embodiment, the first groove 61 can be arranged on the side of the isolation part 201 close to the rolling brush body 212, which is convenient to process and can ensure that the first groove 61 and the flexible blocking piece 62 better cooperate, so that the flexible blocking piece 62 and the isolation part 201 have better blocking and isolation effect on garbage, especially linear objects.

[0134] The matching piece 112 is provided with a first groove 61. In the first direction, the projection outer contour of the inner wall surface of the first groove 61 is an arc surface. When the arc surface of the first groove 61 cooperates with the flexible blocking piece 62, the friction force acting on the flexible blocking piece 62 can be reduced, so that the movement of the flexible blocking piece 62 is more smooth.

[0135] In the first direction, when the projection outer contour of the flexible blocking piece 62 is a circle, the cooperation of the circular flexible blocking piece 62 and the arc surface of the first groove 61 can further ensure that there is no gap between the flexible blocking piece 62 and the first groove 61, and the blocking effect on garbage, linear objects, dust and the like is better.

[0136] In the first direction, the connecting part 202 of the matching piece 112 is located between the isolation part 201 and the frame 11. The avoiding space 113 in this embodiment includes an avoiding groove 1132 and a through opening 1133. In the third direction, the avoiding groove 1132 is arranged on the bottom side of the connecting part 202 of the matching piece 112. In the second direction, the through opening 1133 is arranged on the opposite sides of the matching piece 112 and communicates with the avoiding groove 1132 and the opening 111. The avoiding space 113 formed by the avoiding groove 1132 and the opening 111 can provide sufficient rotation space for the opposite sides of the support 12, so that the isolation part 201 of the matching piece 112 can isolate the support 12 and the rolling brush body 212 while ensuring that the support 12 can better drive the scraping strip 22 to closely adhere to the surface to be cleaned.

[0137] In another embodiment of the present application, as Figure 9As shown, the avoidance space 113 in the embodiment includes a second opening 1131 and an avoidance groove 1132. In the first direction, the second opening 1131 is located on the side of the isolation portion 201 of the fitting part 112 away from the opening 111. The second opening 1131 is arranged on the side of the isolation portion 201 of the opposite side of the rolling brush body 212 away from the opening 111. In the second direction, the avoidance groove 1132 is arranged in the connecting portion 202 and communicates the second opening 1131 and the opening 111. The second opening 1131 and the avoidance groove 1132 are convenient to process, provide sufficient space for the rotation of the support 12, and can simplify the assembly steps of the fitting part 112, the frame 11 and the support 12, and the assembly is efficient and convenient.

[0138] The support 12 (such as the frame plate 121) in the embodiment can specifically include a first connecting segment 1211, a first swing arm 1212, a second swing arm 1213 and a second connecting segment 1214. In the first direction, the opposite ends of the first connecting segment 1211 extend to the avoidance space 113 and are rotationally connected with the inner wall surface of the avoidance space 113. When the avoidance space 113 includes the avoidance groove 1132 and the through opening 1133, the opposite ends of the first connecting segment 1211 extend to the avoidance groove 1132 through the through opening 1133. When the avoidance space 113 includes the second opening 1131 and the avoidance groove 1132, the opposite ends of the first connecting segment 1211 extend to the second opening 1131 through the avoidance groove 1132.

[0139] In the first direction, the first swing arm 1212 is located on one side of the first connecting segment 1211 and is gap-fitted with the inner wall surface of the avoidance space 113 (such as the second opening 1131 or the avoidance groove 1132). In the first direction, the second swing arm 1213 is located on the other side of the first connecting segment 1211 and is gap-fitted with the inner wall surface of the avoidance space 113. In the second direction, the second connecting segment 1214 is located between the first swing arm 1212 and the second swing arm 1213 away from the first connecting segment 1211, and the scraping strip 22 is connected with the second connecting segment 1214.

[0140] It can be seen that, in the embodiment, the first swing arm 1212 and the second swing arm 1213 are respectively located on opposite sides of the support 12 along the first direction, and are in gap cooperation with the inner wall surface of the corresponding avoiding space 113, so that the first swing arm 1212 and the second swing arm 1213 can drive the second connecting section 1214 and the scraping strip 22 to reciprocate along the third direction. At the same time, the first swing arm 1212 and the second swing arm 1213 located in the avoiding space 113 are located on the side of the isolation part 201 of the cooperating piece 112 away from the roller brush main body 212. The movement of the first swing arm 1212 and the second swing arm 1213 along the third direction will not affect the gap between the roller brush main body 212 and the isolation part 201 of the cooperating piece 112. Therefore, linear objects and garbage are not easy to enter between the roller brush main body 212 and the cooperating piece 112, the rotation reliability of the roller brush main body 212 is improved, and the effect of no linear object winding relative to both ends of the roller brush main body 212 is realized. The first swing arm 1212 and the second swing arm 1213 do not interfere with the rotating piece 211, ensuring the stable operation of the rotating piece 211. The first swing arm 1212 and the second swing arm 1213 also do not press the roller brush main body 212, reducing the extrusion of the support 12 (the frame plate 121) on the roller brush main body 212, so that the linear objects and garbage can move with the rotation of the roller brush main body 212, avoiding the linear objects winding on the rotating piece 211, and improving the reliability of the roller brush cover assembly.

[0141] In the embodiment, the scraping strip 22 can be efficiently and conveniently mounted on the second connecting section 1214 by setting the clamping structure 30 between the scraping strip 22 and the second connecting section 1214. As shown in Figure 6 the clamping structure 30 can include a clamping groove 31 and a clamping protrusion 32. The clamping groove 31 is arranged on the second connecting section 1214 and extends along the first direction, and the clamping protrusion 32 is arranged on one side of the scraping strip 22 close to the second connecting section 1214 and is embedded in the clamping groove 31.

[0142] Secondly, since the scraping strip 22 can be arranged in a flexible structure, in order to ensure that the scraping strip 22 produces a large bending deformation when scraping the surface to be cleaned and reduces the cleaning effect, the scraping component in the embodiment can further include a pressing plate 13. The pressing plate 13 is connected with the second connecting section 1214 and at least partially covers one side of the scraping strip 22 away from the second connecting section 1214, and at least part of the scraping strip 22 extending out of the outside of the pressing plate 13 and the second connecting section 1214 is arranged opposite to the roller brush main body 212. The pressing plate 13 can ensure that the whole scraping strip 22 will not produce a large bending deformation, thereby improving the cleaning effect of the scraping strip 22.

[0143] Secondly, to avoid the second connecting section 1214 moving a large amplitude away from the frame 11, affecting the user experience, the embodiment can also include a resilient member, which is detachably mounted on one side of the frame 11 close to the second connecting section 1214. The resilient member can apply a force to the frame 11 towards the frame 11, thereby ensuring that the second connecting section 1214 of the frame plate 121 moves a large amplitude away from the frame 11. Specifically, when the scraping strip 22 is lifted by an external force, the scraping strip 22 pushes the second connecting section 1214 to compress the resilient member, and the elastic deformation of the resilient member makes the scraping strip 22 and the second connecting section 1214 move away from the surface to be cleaned. When the external force acting on the scraping strip 22 is removed, the scraping strip 22 returns to be in close contact with the surface to be cleaned, and the elastic deformation of the resilient member is eliminated and can ensure that the second connecting section 1214 does not move a large amplitude by applying a force to the frame 11 towards the frame 11.

[0144] The resilient member can be a spring. As shown in Figure 10 and Figure 17 shown, the resilient member in the embodiment can specifically include a flexible connecting strip 14, which is detachably mounted on one side of the frame 11 close to the second connecting section 1214 and at least partially covers one side of the pressing plate 13 away from the scraping strip 22. In this way, the flexible connecting strip 14 supports the pressing plate 13 to apply a force to the second connecting section 1214 towards the frame 11, ensuring that the moving amplitude of the second connecting section 1214 is not too large. The flexible connecting strip 14 can be separately provided with the scraping strip 22 or integrally formed.

[0145] A sleeve structure 40 is provided between the flexible connecting strip 14 and the frame 11, as shown in Figure 10 The sleeve structure 40 includes a sleeve flange 41 and a sleeve hole 42. The sleeve flange 41 is provided on one side of the frame 11 away from the scraping strip 22 and located between the cooperating members 112 at both ends of the roller brush body 212. The sleeve flange 41 includes a plurality of sleeve flanges 41, which are spaced apart along the first direction. The sleeve hole 42 includes a plurality of sleeve holes 42, which are provided through the flexible connecting strip 14 and correspond one-to-one to the plurality of sleeve flanges 41. The plurality of sleeve holes 42 are adapted to the plurality of sleeve flanges 41 and are correspondingly sleeved on the sleeve flange 41, so that the connection between the flexible connecting strip 14 and the frame 11 is stable and reliable, and the assembly is efficient and convenient. The part of the flexible connecting strip 14 located in the sleeve hole 42 is provided to one side of the frame 11 close to the scraping strip 22 and covers the pressing plate 13.

[0146] The support 12 can also include a rotating connection structure 122, and the opposite ends of the first connecting section 1211 in the first direction can be rotatably connected to the inner wall surface of the second opening 1131 through the rotating connection structure 122. In combination with Figure 10 and Figure 11It can be seen that the rotating connection structure 122 can include a bearing and a connecting shaft 1222, the bearing can be arranged in a bearing seat on the inner wall surface of the second opening 1131, and the connecting shaft 1222 is sleeved in the bearing to realize rotating connection, but this kind of assembly is difficult and has high cost. In this embodiment, the rotating connection structure 122 can include a shaft hole 1221 and a connecting shaft 1222, the connecting shaft 1222 is arranged at the end of the opposite two ends of the first connecting section 1211, the shaft hole 1221 is arranged on the inner wall surface of the second opening 1131 close to the connecting shaft 1222, and the connecting shaft 1222 and the shaft hole 1221 are in clearance fit, so as to realize the rotating connection between the first connecting section 1211 and the frame 11. Of course, the shaft hole 1221 can also be arranged at the end of the first connecting section 1211, the connecting shaft 1222 is protruded on the inner wall surface of the second opening 1131 close to the end of the first connecting section 1211, or the first connecting section 1211 is provided with the shaft hole 1221 at one end and the connecting shaft 1222 at the other end, and the inner wall surface of the second opening 1131 on one side of the frame 11 is provided with the connecting shaft 1222 and the inner wall surface of the second opening 1131 on the other side is provided with the shaft hole 1221. In this embodiment, the rotating connection structure 122 including the shaft hole 1221 and the connecting shaft 1222 is efficient, low in assembly difficulty, and cost-saving.

[0147] The matching piece 112 in the embodiment is connected with the frame 11 or in an integrated structure with the frame 11. When in an integrated structure, the processing is more convenient, the assembly steps of the roller brush cover assembly are reduced, and the production cost is reduced. The matching piece 112 can be integrally formed with the frame 11 through the connecting portion 202. The isolation portion 201 of the matching piece 112 is connected (such as welding, fixed connection) or integrally formed with the connecting portion 202, and the isolation portion 201 is located between the opening 111 and the support 12. After the roller brush body 212 is installed in the opening 111, the gap between the isolation portion 201 and the end portion of the roller brush body 212 remains constant regardless of whether the support 12 rotates, so that the linear object is not easy to enter the end portion of the roller brush body 212.

[0148] The matching piece 112 and the frame 11 in the embodiment are at least one of which is provided with a second groove 1122. In the third direction, the second groove 1122 is located on the upper side of the roller brush cover assembly. The second groove 1122 can be arranged on the isolation portion 201 of the matching piece 112, the second groove can also be arranged on the frame 11, or the second groove 1122 can be arranged between the connecting portion 202 of the matching piece 112 and the frame 11. In this embodiment, the second groove 1122 can play a supporting and clamping role for the rotating piece 211 and the roller brush body 212 when the roller brush body 212 is connected with the driving mechanism through the rotating piece 211, so as to ensure the stability of the roller brush body 212 after being connected with the driving mechanism.

[0149] As shown in Figure 23 , the fitting part 112 is provided with the first groove 61 (i.e. the first groove 61 provided by the isolation part 201), and along the first direction, the first groove 61 is located between the opening 111 and the second groove 1122. After the first groove 61 is interference-fitted with the flexible barrier 62 installed on the roll brush body 212, the first groove 61 and the flexible barrier 62 can more efficiently block the garbage and linear objects (such as hair and thread) to avoid the garbage and linear objects from entering the second groove 1122 to entangle the rotating part 211. This can avoid the phenomenon of locked-rotor of the motor of the driving mechanism connected with the rotating part 211, and make the roll brush body 212 operate more reliably and smoothly.

[0150] In addition, as shown in Figure 29 , along the first direction, the inner wall surface of the first groove 61 has a first projected outer contour, and the inner wall surface of the second groove has a second projected outer contour, and the first projected outer contour surrounds the outer periphery of the second projected outer contour and has a first spacing between the second projected outer contour. That is, along the third direction, the recess depth of the first groove 61 is deeper than the recess depth of the second groove, and after the first groove 61 is fitted with the flexible barrier 62, the garbage and linear objects are less likely to enter the second groove, and the blocking effect is better. Of course, the recess depths of the first groove 61 and the second groove can also be set the same, but it has been verified that when the first groove 61 is recessed deeper, the first groove 61 and the flexible barrier 62 play a better blocking effect.

[0151] The second embodiment of the present application also provides a cleaning module, which comprises a roll brush cover assembly and a roll brush part 21. The structure of the roll brush cover assembly is specifically described in the first embodiment of the present application, and will not be repeated here. The roll brush part 21 comprises a roll brush body 212, and the roll brush body 212 is installed in the opening 111. At least one end of the roll brush body 212 is a fixed end 2120, and the fixed end 2120 is an end surface of the roll brush body 212. The fixed end 2120 is at least used for connecting with the driving mechanism of the cleaning device. Along the first direction, the fitting part 112 is at least partially located between the fixed end 2120 and the support 12, so that at least part of the fitting part 112 can isolate the roll brush body 212 and the support 12.

[0152] Therefore, during the rotation of the support 12 relative to the frame 11, regardless of the changes in the gaps between the support 12, the frame 11, and the mating parts 112, the gap between the fixed end 2120 of the roller brush body 212 and the mating parts 112 remains constant because the mating parts 112 are stationary relative to the frame 11. The gap between the roller brush body 212 and the mating parts 112 does not increase with the rotation of the support 12. Therefore, linear objects swept up by the roller brush body 212 are less likely to enter between the fixed end 2120 and the mating parts 112, and thus will not become entangled in the fixed end 2120 and the drive mechanism. Other debris and linear objects will move away from the fixed end 2120 of the roller brush body 212 as the roller brush body 212 rotates, and finally, the debris and linear objects will be collected by the dust box of the cleaning equipment. Therefore, regardless of whether the bracket 12 rotates relative to the frame 11, the gap between the fixed end 2120 of the roller brush body 212 and the mating part 112 will not increase, reducing the risk that the linear object wrapped around the roller brush body 212 will enter the end of the roller brush body 212 through the gap between the fixed end 2120 of the roller brush body 212 and the mating part 112.

[0153] like Figures 22 to 28 As shown, a blocking structure 60 is provided between at least one end of the roller brush body 212 and the mating member 112 along the first direction. The blocking structure 60 can further prevent linear objects and other debris swept up by the roller brush body 212 from moving towards the support 12 along the first direction. During the rotation of the roller brush body 212, even if the linear objects move towards both ends of the roller brush body 212 along the first direction as the roller brush body 212 rotates, the blocking structure 60 will prevent the linear objects from being blocked on the side of the mating member 112 near the roller brush body 212, thereby preventing the rotating part 211 of the roller brush component 21 from being entangled by the linear objects.

[0154] The blocking structure 60 in this embodiment includes a first groove 61 and a flexible blocking member 62. Along the first direction, the first groove 61 is disposed on the side of the mating member 112 near the roller brush body 212. That is, the first groove 61 is disposed on the isolation portion 201 of the mating member 112. Along the first direction, the flexible blocking member 62 is disposed at at least one end of the roller brush body 212 and can rotate with the roller brush body 212. In other words, the flexible blocking member 62 is disposed at one end of the roller brush body 212, or the flexible blocking members 62 are disposed at both opposite ends of the roller brush body 212.

[0155] In the first direction, at least part of the flexible blocking piece 62 is located in the first groove 61 and is in interference fit with the inner wall surface of the first groove 61. Thus, during rotation of the roller brush body 212, the flexible blocking piece 62 also rotates with the roller brush body 212. If garbage and / or linear objects have a tendency to move in the direction of the fitting piece 112 during this process, the flexible blocking piece 62 and the interference fit between the flexible blocking piece 62 and the inner wall surface of the first groove 61 will effectively block these garbage and / or linear objects, preventing garbage and / or linear objects from continuing to move, achieving the purpose of winding linear objects at both ends of the roller brush component 21.

[0156] Of course, in other embodiments, the flexible blocking piece 62 can also be mounted to the inner wall surface of the first groove 61 by a configured mounting structure, and the flexible blocking piece 62 will not interfere with the rotation of the roller brush body 212, thereby also achieving the blocking effect of garbage and linear objects.

[0157] As shown in Figure 29 In the first direction, the projection outer contour of the inner wall surface of the first groove 61 is an arc surface, and in the first direction, the projection outer contour of the flexible blocking piece 62 is a circle, and the outer diameter of the flexible blocking piece 62 is greater than the inner diameter of the first groove 61. Thus, by making the outer diameter of the flexible blocking piece 62 greater than the inner diameter of the first groove 61, the flexible blocking piece 62 can be in interference fit with the inner wall surface of the first groove 61, effectively blocking garbage and linear objects. The circular flexible blocking piece 62 and the arc surface of the first groove 61 can also be more closely fitted, and there is no gap between the two, and the blocking effect on garbage and linear objects is better.

[0158] As shown in Figure 26As shown, the flexible barrier 62 includes a carrier sheet 621 and a tuft row 622. The carrier sheet 621 is arranged at the end of the roller brush body 212 and circumferentially around the roller brush body 212. In the first direction, the carrier sheet 621 is at least partially located in the first groove 61. The tuft row 622 includes a plurality of tufts. The plurality of tufts is arranged on the carrier sheet 621 in the axial direction of the roller brush body 212. The plurality of tufts can be arranged in the axial direction of the roller brush body 212 in a spaced manner or in an adjacent manner, and the present embodiment is not limited thereto. The tuft row 622 includes a plurality of rows. The plurality of rows of the tuft row 622 is arranged on the carrier sheet 621 in the circumferential direction of the roller brush body 212 and abuts the inner wall surface of the first groove 61. Thus, the tuft row 622 arranged on the carrier sheet 621 abuts the inner wall surface of the first groove 61, so as to realize the interference fit of the flexible barrier 62 and the first groove 61. Moreover, the tuft row 622 cooperates with the first groove 61, which can further reduce the friction between the flexible barrier 62 and the first groove 61, so as to ensure that the load of the driving mechanism for driving the rotation of the roller brush body 212 can be reduced in the process of the rotation of the flexible barrier 62 with the roller brush body 212, so that the motor of the driving mechanism will not be overloaded, and the noise of the motor will be smaller, and the reliability of the cleaning equipment using the roller brush cover assembly is improved.

[0159] The interference amount between the flexible barrier 62 and the inner wall surface of the first groove 61 is H (i.e., the difference between the outer diameter of the flexible barrier 62 and the inner diameter of the first groove 61), and H satisfies the relationship: 0mm≤H≤0.5mm. In this way, the flexible barrier 62 can be interference fitted with the inner wall surface of the first groove 61, so as to block linear objects and / or other garbage between the flexible barrier 62 and the roller brush body 212. Moreover, since H is not greater than 0.5mm, the friction between the flexible barrier 62 and the first groove 61 can be avoided due to the excessive interference amount. H can include one of 0mm, 0.1mm, 0.14mm, 0.18mm, 0.2mm, 0.23mm, 0.25mm, 0.27mm, 0.3mm, 0.35mm, 0.4mm, 0.46mm, 0.49mm, 0.5mm, or any other value greater than 0mm but not greater than 0.5mm.

[0160] In some embodiments, the roller brush body 212 includes a roller 2121, a first brush strip 2122, and a second brush strip 2123, with the roller 2121 installed within the opening 111. The first brush strip 2122 has a strip-shaped flange structure. The second brush strip 2123 has a bristle structure. Along the circumference of the roller 2121, the first brush strip 2122 and the second brush strip 2123 are spaced apart on the surface of the roller 2121. Along a first direction, the projected outer contour of the first brush strip 2122 lies within the projected outer contour of the flexible blocking member 62. That is, along the radial direction of the roller 2121, the flexible blocking member 62 is at least partially protruding from the outer surface of the first brush strip. When the flexible blocking member 62 is an overall annular structure, the outer diameter of the flexible blocking member 62 is larger than the outer diameter of the first brush strip, so that the flexible blocking member 62 has a better blocking effect on garbage, linear objects, etc.

[0161] When the roller brush component 21 also includes a rotating member 211, the rotating member 211 rests on at least one of the mating member 112 and the frame 11 and is connected to the roller brush body 212. Specifically, when at least one of the mating member 112 and the frame 11 is provided with a second groove 1122, the rotating member 211 rests on the second groove 1122, and the rotating member 211 at at least one end of the roller brush body 212 is connected to the drive mechanism. A flexible blocking member 62 is installed on the outer peripheral surface of at least one of the rotating member 211 and the roller brush body 212. Figure 27 As shown, in this embodiment, a partition area 215 can be provided at the end of the roller brush body 212 for installing the flexible blocking member 62, or a partition area 215 can be provided on the side of the rotating member 211 near the roller brush body 212 for installing the flexible blocking member 62, or partition areas 215 for installing the flexible blocking member 62 can be provided at both the end of the roller brush body 212 and the side of the rotating member 211 near the roller brush body 212. The bearing piece 621 of the flexible blocking member 62 can be attached to the partition area 215 on the side facing away from the bristle row 622, which is easy to assemble, convenient and efficient. When the partition area 215 is provided on the rotating member 211, it can be specifically provided on the outer flange 101 of the rotating shaft 2111. The outer flange 101 is a structure that protrudes radially from the rotating shaft 2111 and is located at the end of the roller brush body 212.

[0162] In some embodiments, the roller brush body 212 includes a roller 2121, a first brush strip 2122, and a second brush strip 2123, with the roller 2121 installed within the opening 111. The first brush strip 2122 has a strip-shaped flange structure. The second brush strip 2123 has a bristle structure, and the first brush strip 2122 and the second brush strip 2123 are spaced apart on the surface of the roller 2121 along its circumference. Wherein:

[0163] In the first direction, the projected outer contour of the flexible barrier 62 is within the projected outer contour of the first brush strip 2122, i.e., the outer diameter of the flexible barrier 62 is smaller than the outer diameter of the first brush strip 2122, so that the size of the fitting member 112 and the first groove 61 arranged therein can be correspondingly reduced, and the obstacle surmounting capability of the roll brush cover assembly when the cleaning device moves can be improved.

[0164] In the second direction, the first brush strip 2122 has a third projected outer contour, and the fitting member 112 has a fourth projected outer contour, and in the third direction, the bottom of the third projected outer contour is on the lower side of the fourth projected outer contour. That is, the size of the fitting member 112 can be reduced to the size of the flexible barrier 62 to ensure the obstacle surmounting capability. When the isolation portion 201 of the fitting member 112 is a convex arc block 011, the outer diameter of the convex arc block 011 will be smaller than the outer diameter of the first brush strip 2122, so as to improve the obstacle surmounting capability of the cleaning device using the roll brush cover assembly.

[0165] The first brush strip 2122 and the second brush strip 2123 both have a mounting gap with the fitting member 112, so that the first brush strip 2122 and the second brush strip 2123 will not rub against the fitting member 112, thereby improving the rotation performance of the roll brush body 212 and avoiding overloading of the driving mechanism.

[0166] In the first direction, the end points of the opposite ends of the first brush strip 2122 are closer to the fitting member 112 than the end points of the opposite ends of the second brush strip 2123, and in the first direction, the first brush strip 2122 has a fourth gap with the fitting member 112. The fourth gap is greater than 0 mm and not greater than 0.2 mm, so as to avoid the first brush strip 2122 rubbing against the fitting member 112, and the fourth gap not greater than 0.2 mm can also avoid the first brush strip 2122 being too short, and can also avoid a large blank area between the roll brush body 212 and the fitting member 112, so that the overall structure is more compact and reasonable. The size of the fourth gap can include one of 0.03 mm, 0.05 mm, 0.08 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, or any other numerical value greater than 0 mm and not greater than 0.2 mm.

[0167] In this embodiment, the materials of the support sheet 621 and the pile 622 of the flexible blocking member 62 may include at least one of flocked sheet, felt, foam, etc. For example, both the support sheet 621 and the pile sheet may be formed by processing flocked sheet, or the support sheet 621 may be formed by processing felt, and the pile sheet may be formed by processing flocked sheet, etc. This embodiment does not impose a unique limitation on this. In this embodiment, the rotating member 211 may be integrally formed with the roller 2121 of the roller brush body 212. Alternatively, the rotating member 211 may be assembled and connected to the roller brush body 212. In this case, in some embodiments, the rotating member 211 may include a rotating shaft 2111 and a support structure 2112. In some embodiments, the support structure 2112 may include at least one of a bushing and a sliding bearing. The rotating shaft 2111 can be fixedly connected to the fixed end 2120 of the roller brush body 212, or the length of the rotating shaft 2111 can be greater than the length of the roller 2121, with the rotating shaft 2111 sleeved inside the roller 2121 and its opposite ends extending out of the roller 2121. One end of the rotating shaft 2111 can be sleeved with the support structure 2112, which can be placed in the second groove 1122. The other end of the rotating shaft 2111 can be directly placed in the second groove 1122 and connected to the drive mechanism, or it can be placed in the second groove 1122 through another support structure 2112 and connected to the drive mechanism.

[0168] The roller brush cover assembly includes a scraping component, which further includes a pressure plate 13 connected to a bracket 12 (specifically, the pressure plate is connected to the second connecting section 1214 of the bracket 12). Along a second direction, the pressure plate 13 at least partially covers the side of the scraper 22 opposite to the roller brush body 212, and the scraper 22 at least partially extends beyond the outer side of the pressure plate 13 and is disposed opposite to the roller brush body 212. The pressure plate 13 ensures that when the scraper 22 is subjected to the reaction force of the surface to be cleaned, the scraper 22 does not undergo significant bending deformation, thereby improving the cleaning effect of the scraper 22.

[0169] like Figure 22 As shown, along the first direction, a fifth gap 131 is formed between at least one end of the pressure plate 13 and the support 12. If too many thread-like objects and debris are stuffed into the fifth gap 131, these objects may enter the rotating member 211 after accumulating to a certain extent or under the action of external force collision or scraping. To further ensure that the two ends of the roller brush member 21 are not entangled with thread-like objects, along the second direction, the fifth gap 131 is positioned opposite to the opening of the mating member 112. Therefore, the opening of the fifth gap 131 is blocked by the mating member 112 (specifically, by the isolation portion 201 of the mating member 112), making it difficult for debris, especially thread-like objects such as hair and thin threads, to get stuck in the gap between the pressure plate 13 and the support 12.

[0170] The fifth gap 131 can be a long rectangular shape extending along the second direction, or other shapes (such as irregular shapes like curved shape, horn shape, etc.) different from the long rectangular shape extending along the second direction, and the embodiment is not limited to be the only one.

[0171] When the bracket 12 includes the first swing arm 1212, the second swing arm 1213, and the second connecting segment 1214, the pressing plate 13 and the scraping strip 22 are connected with the second connecting segment 1214, wherein:

[0172] In the first direction, the fifth gap 131 is located between the end of the pressing plate 13 and the first swing arm 1212, and in the first direction, the end of the pressing plate 13 is located between the outer edge of the cooperating part 112 close to the side of the roller brush body 212 and the first swing arm 1212, so that the fifth gap 131 can be arranged opposite to the cooperating part 112 and be blocked by the cooperating part 112.

[0173] In combination Figure 22 And Figure 24 It can be seen that in the first direction, the fifth gap 131 is also located between the end of the pressing plate 13 and the second swing arm 1213. In the first direction, the end of the pressing plate 13 is located between the outer edge of the cooperating part 112 close to the side of the roller brush body 212 and the second swing arm 1213, so that the fifth gap 131 can be arranged opposite to the cooperating part 112 and be blocked by the cooperating part 112.

[0174] That is, the opposite ends of the pressing plate 13 can extend to the first swing arm 1212 and / or the second swing arm 1213 of the bracket 12 close to the cooperating part 112 in the first direction. In the normal working state, the fifth gap 131 between the pressing plate 13 and the bracket 12 is not exposed to the cleaning range of the roller brush body 212, so as to effectively prevent the fifth gap 131 from being filled with garbage and linear objects. The pressing plate 13 can be fixedly connected with the second connecting segment 1214 by fasteners (such as screws, bolts, etc.) and press the scraping strip 22.

[0175] The rolling brush body 212 in the embodiment can include at least one of a first rolling brush structure and a second rolling brush structure, and the first rolling brush structure and the second rolling brush structure are each one or more. The first rolling brush structure is a rolling brush structure with one end of the opposite ends being a fixed end 2120, and the second rolling brush structure is a rolling brush structure with both ends being fixed ends 2120. Regardless of whether the rolling brush body 212 is the first rolling brush structure or the second rolling brush structure, since the cooperating part 112 is located between the fixed end 2120 and the support 12, the gap between the fixed end 2120 of the first rolling brush structure and the second rolling brush structure and the cooperating part 112 will not be affected by the rotation of the support 12, and linear objects are not easy to enter between the fixed end 2120 of the first rolling brush structure and the second rolling brush structure and the cooperating part 112, thereby improving the running stability of the first rolling brush structure and the second rolling brush structure. The rolling brush body 212 can be only one first rolling brush structure or one second rolling brush structure, or a combination of two coaxially arranged first rolling brush structures and second rolling brush structures, or a combination of four first rolling brush structures, or a combination of multiple second rolling brush structures, etc., and the embodiment is not limited to only one.

[0176] As Figure 12As shown, when the roller brush body 212 is the second roller brush structure, to ensure that the fixed ends 2120 at the opposite ends of the second roller brush structure do not entangle the linear objects, at this time, the second roller brush structure in this embodiment can include a roller 2121, first brush strips 2122 and second brush strips 2123. The first brush strips 2122 are strip-shaped flange structures, and the second brush strips 2123 are bristle structures. The bristle structure can be arranged in a strip shape by a plurality of clusters of independent bristles, or the bristle structure can be obtained after a plurality of clusters of bristles are arranged at intervals on a strip-shaped base. The roller 2121 is installed in the opening 111. Specifically, the roller 2121 can be sleeved on the rotating member 211 and located in the opening 111. Along the circumference of the roller 2121, the first brush strips 2122 and the second brush strips 2123 are arranged at intervals on the surface of the roller 2121. The first brush strips 2122 and the second brush strips 2123 can each include a plurality of strips, and the second brush strips 2123 are arranged at intervals between adjacent two first brush strips 2122. Along the first direction, at least one of the first brush strips 2122 and the second brush strips 2123 includes a first section 1231 and a second section 1232. The first section 1231 and the second section 1232 respectively extend in a spiral shape from the opposite ends of the roller 2121 to any position between the opposite ends of the roller 2121 and meet at the any position to form a V-shaped structure. The any position can be a middle position between the opposite ends of the roller 2121 or a position between the middle position and the end of the roller 2121. At this time, the dust suction port 51 on the cleaning device can be arranged opposite the V-shaped structure of the second roller brush structure. The opposite end faces of the roller 2121 along the axial direction of the roller 2121 are both fixed ends 2120. The fixed ends 2120 are connected with the driving mechanism. Thus, when the roller 2121 rotates, the linear objects and other garbage can move to the middle of the roller 2121 along the rotating first brush strips 2122 and second brush strips 2123 and then enter the dust box from the dust suction port 51. In addition, the gap between the fixed ends 2120 and the cooperating member 112 always remains unchanged. Therefore, the linear objects and other garbage are not easy to enter between the fixed ends 2120 of the second roller brush structure and the cooperating member 112, or the rotating member 211, thereby achieving the effect that the opposite ends of the second roller brush structure are not entangled with linear objects, and improving the cleaning effect and dust collection effect of the cleaning device using the cleaning module.

[0177] The roller brush assembly 21 in this embodiment further includes an unwinding component. The unwinding component is installed at the V-shaped structure of the first brush strips 2122 and the second brush strips 2123. The unwinding component can cut and comb or cut the linear objects (such as hair) gathered at the V-shaped structure. The cut linear objects are smaller and are easier to be collected by the dust collection port in the cleaning device. The unwinding component can be installed on the roller brush assembly 21, or installed on the bottom shell 50 of the cleaning device close to one side of the roller brush body 212 and arranged opposite the V-shaped structure. The unwinding component in this embodiment can include at least one of a comb tooth 23 and a cutting blade. As shown, the comb tooth 23 can be arranged at the V-shaped structure of the first brush strips 2122 and the second brush strips 2123.Figure 12 As shown, if the winding component is the comb tooth 23, the bottom of the comb tooth 23 can be connected with the outer side wall of the rotating shaft 2111, and along the radial direction of the rotating shaft 2111, the part of the comb tooth 23 away from the rotating shaft 2111 penetrates the roller 2121 and is located at the V-shaped structure, so that the linear object will be cut and combed by the comb tooth 23 when moving to the V-shaped structure, thereby being more efficiently collected by the suction port.

[0178] In some embodiments of the present application, when the rolling brush body 212 is a first rolling brush structure of single cantilever, the first rolling brush structure of the rolling brush body 212 can include a roller 2121, a first brush bar 2122 and a second brush bar 2123. At this time, the roller 2121 is connected with the driving mechanism at one end along the axis of the roller 2121 as a fixed end 2120, the first brush bar 2122 is a bar-shaped flange structure, and the second brush bar 2123 is a bristle structure. In the first direction, the first brush bar 2122 and the second brush bar 2123 can extend spirally from the fixed end 2120 of the roller 2121 to the end of the roller 2121 away from the fixed end 2120. Then the suction port 51 of the cleaning device can be arranged opposite to the end of the first rolling brush away from the fixed end 2120. Thus, during the rotation cleaning process of the first rolling brush structure, since the gap between the fixed end 2120 of the first rolling brush structure and the cooperating part 112 remains unchanged, the linear object on the first brush bar 2122 and the second brush bar 2123 not only is not easy to enter the fixed end 2120 of the first rolling brush structure, but also can move to the suction port 51 in the direction away from the fixed end 2120 to be recycled by the suction port 51 along with the rotation of the first brush bar 2122 and the second brush bar 2123.

[0179] As Figure 14As shown, when the rolling brush body 212 is two coaxially arranged first rolling brush structures, the rolling cylinder 2121 in the embodiment can include a first rolling cylinder segment 21211 and a second rolling cylinder segment 21212. The first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 are both located in the opening 111, the second rolling cylinder segment 21212 is located on one side of the first rolling cylinder segment 21211 in the first direction and coaxially arranged with the first rolling cylinder segment 21211, and the ends of the first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 away from each other are fixed ends 2120, the fixed end 2120 of the first rolling cylinder segment 21211 and the bracket 12 are provided with a cooperating part 112, and the fixed end 2120 of the second rolling cylinder segment 21212 and the bracket 12 are also provided with a cooperating part 112, so that the fixed end 2120 of the first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 and the cooperating part 112 are not easy to enter the linear object. The fixed end 2120 of the first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 away from each other can be matched with the cooperating part 112 through the rotating part 211. Specifically, when the rotating part 211 includes a rotating shaft 2111 and a supporting structure 2112, the first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 can be respectively sleeved on different rotating shafts 2111, and then the rotating shaft 2111 is matched with the cooperating part 112 through the supporting structure 2112, that is, the first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 and the rotating part 211 form a cantilever beam type assembly structure. The first brush strip 2122 is a strip-shaped flange structure, and the second brush strip 2123 is a bristle structure. Along the circumference of the first rolling cylinder segment 21211, the surfaces of the first rolling cylinder segment 21211 and the second rolling cylinder segment 21212 are both spaced apart to be provided with the first brush strip 2122 and the second brush strip 2123. That is, the first rolling cylinder segment 21211 and the first brush strip 2122 and the second brush strip 2123 on the surface thereof constitute one of the first rolling brush structures, and the second rolling cylinder segment 21212 and the first brush strip 2122 and the second brush strip 2123 on the surface thereof constitute another first rolling brush structure.

[0180] The first brush strip 2122 and the second brush strip 2123 on the first roller section 21211 extend spirally from one end of the first roller section 21211 away from the second roller section 21212 to the other end close to the second roller section 21212, and the first brush strip 2122 and the second brush strip 2123 on the second roller section 21212 extend spirally from one end of the second roller section 21212 away from the first roller section 21211 to the other end close to the first roller section 21211. At this time, the dust suction port 51 of the cleaning device can be arranged opposite to the adjacent positions of the first roller section 21211 and the second roller section 21212, that is, the dust suction port is arranged opposite to the end of the first brush structure away from the fixed end 2120. During the rotation of the first roller section 21211, the linear objects and garbage can move along the first brush strip 2122 and the second brush strip 2123 on the first roller section 21211 towards the second roller section 21212. During the rotation of the second roller section 21212, the linear objects and other garbage can move along the first brush strip 2122 and the second brush strip 2123 on the second roller section 21212 towards the first roller section 21211, and then converge with the linear objects and garbage conveyed by the first roller section 21211, and are recycled by the dust suction port 51. In this structure, the linear objects and other garbage are not easy to entangle and gather on the fixed end 2120 of the first brush structure and the rotating part 211, and the cleaning effect and dust collection effect can be effectively guaranteed.

[0181] In some embodiments of the present application, the brush body 212 can also be a combination of the second brush structure and the first brush structure. At this time, the brush body 212 in the present embodiment includes a roller 2121, a first brush strip 2122 and a second brush strip 2123, as shown in FIG. 8. Figure 15As shown, the roller 2121 comprises a first roller segment 21211, a second roller segment 21212 and a third roller segment 21213. The first roller segment 21211, the second roller segment 21212 and the third roller segment 21213 are all located in the opening 111, the second roller segment 21212 is located at one side of the first roller segment 21211 along the first direction and coaxially arranged with the first roller segment 21211, and the ends of the first roller segment 21211 and the second roller segment 21212 away from each other are both fixed ends 2120, the fixed end 2120 of the first roller segment 21211 and the bracket 12 have a matching part 112 therebetween, and the fixed end 2120 of the second roller segment 21212 and the bracket 12 also have a matching part therebetween. The third roller segment 21213 is located at one side of the first roller segment 21211 and the second roller segment 21212 along the second direction, the opposite ends of the third roller segment 21213 are both fixed ends 2120, and the fixed ends 2120 of the opposite ends of the third roller segment 21213 and the bracket 12 are both provided with matching parts 112, and the opposite ends of the third roller segment 21213 are both sleeved with the rotating part 211 to be connected with the driving mechanism after being matched with the matching parts 112. The first brush strip 2122 is a strip-shaped flange structure, and the second brush strip 2123 is a bristle structure, and the surfaces of the first roller segment 21211, the second roller segment 21212 and the third roller segment 21213 are all spaced apart from the first brush strip 2122 and the second brush strip 2123 along the circumference of the first roller segment 21211. Therefore, the first roller segment 21211 and the first brush strip 2122 and the second brush strip 2123 on the surface thereof constitute one of the first roller brush structures, the second roller segment 21212 and the first brush strip 2122 and the second brush strip 2123 on the surface thereof constitute another first roller brush structure coaxially arranged with the aforementioned first roller brush structure, and the third roller segment 21213 and the first brush strip 2122 and the second brush strip 2123 on the surface thereof constitute a second roller brush structure. The second roller brush structure can be located at one side of the first roller brush structure along the second direction and have a mounting gap between the first roller brush structure to avoid interference between the second roller brush structure and the first roller brush structure.

[0182] Along a first direction, the first brush strip 2122 and the second brush strip 2123 on the first roller segment 21211 extend spirally from the end of the first roller segment 21211 away from the end of the second roller segment 21212 to the end near the second roller segment 21212, and the first brush strip 2122 and the second brush strip 2123 on the second roller segment 21212 extend spirally from the end of the second roller segment 21212 away from the end of the first roller segment 21211 to the end near the first roller segment 21211. During the rotation of the first roller segment 21211, linear objects and debris can move towards the second roller segment 21212 along with the first brush strip 2122 and the second brush strip 2123 on the first roller segment 21211. During the rotation of the second roller section 21212, linear objects and other waste can move toward the first roller section 21211 along with the first brush bar 2122 and the second brush bar 2123 on the second roller section 21212, and merge with the linear objects and waste conveyed by the first roller section 21211.

[0183] For the second roller brush structure, along the first direction, at least one of the first brush strip 2122 and the second brush strip 2123 on the third roller segment 21213 includes the first segment 1231 and the second segment 1232 (that is, the structure formed by the third roller segment 21213, the first brush strip 2122, and the second brush strip 2123 is similar to...). Figure 1 (The structure of the roller brush component 21 is the same as that in the previous section). The first segment 1231 and the second segment 1232 extend spirally from the opposite ends of the third roller segment 21213 to any position between the opposite ends of the third roller segment 21213 and converge at any position to form a V-shaped structure. Any position between the opposite ends of the third roller segment 21213 can be the middle position of the third roller segment 21213 or the position between the middle position and the end of the third roller segment 21213. During the rotation of the third roller segment 21213, linear objects and debris will move to the V-shaped structure to converge.

[0184] And, along the third direction, the first brush strip 2122 on the third roller segment 21213 has a fourth projected outer contour, the second brush strip 2123 on the third roller segment 21213 has a fifth projected outer contour, the first brush strip 2122 on the first roller segment 21211 and the second roller segment 21212 has a sixth projected outer contour, and the second brush strip 2123 on the first roller segment 21211 and the second roller segment 21212 has a seventh projected outer contour. Along the second direction, there is a gap between the fourth projected outer contour and the sixth projected outer contour and the seventh projected outer contour, and there is a gap between the fifth projected outer contour and the sixth projected outer contour and the seventh projected outer contour. Thus, during rotation of the first brush structure and the second brush structure, the third roller segment 21213 and the second brush structure formed by the first brush strip 2122 and the second brush strip 2123 can avoid interference with the first brush structure.

[0185] At this time, the present embodiment can oppositely arrange the dust suction port 51 on the cleaning device and the position where the V-shaped structure of the second brush structure and the first roller segment 21211 and the second roller segment 21212 adjacent to each other are arranged (i.e., the side of the first brush structure away from the fixed end 2120). Thus, linear objects and other garbage can be moved to the position where the V-shaped structure and the first roller segment 21211 and the second roller segment 21212 are adjacent to each other by the first brush strip 2122 and the second brush strip 2123 rotating when the roller 2121 rotates, and then enter the dust box from the dust suction port 51. Linear objects and other garbage are less likely to enter the ends of the brush body 212 and the rotating member 211, which not only improves the cleaning effect of the brush cover assembly and the dust collection effect of the cleaning device, but also improves the dust removal rate of the brush body 212, because the second brush structure can clean the garbage that leaks from the side of the first roller segment 21211 and the second roller segment 21212 of the first brush structure close to each other in time. Under this structure, not only can the cleaning efficiency of linear objects and other garbage be higher, but linear objects and other garbage are also less likely to be entangled on the fixed end 2120 and the rotating member 211 of the brush body 212, and the cleaning effect and the dust collection effect can be effectively guaranteed.

[0186] In some other embodiments of the present application, when the rolling brush body 212 is in the second rolling brush structure, the first brush strip 2122 and the second brush strip 2123 can also extend spirally from the fixed end 2120 of the roller 2121 to the other end of the roller 2121 away from the fixed end 2120. In this case, the dust suction port 51 can be arranged opposite to the other end of the roller 2121 away from the fixed end 2120, so that the linear objects and other garbage can be moved from the fixed end 2120 of the roller 2121 to the dust suction port 51 at the other end of the roller 2121 by the first brush strip 2122 and the second brush strip 2123, and then be collected by the dust box. In this case, the linear objects and other garbage are less likely to enter between the second rolling brush structure and the cooperating piece 112 or at the rotating piece 211, thereby improving the cleaning effect and the dust collection effect.

[0187] As shown in Figure 18 , when the cleaning device includes the bottom shell 50, the dust suction port 51 is arranged in the bottom shell 50, the dust suction port 51 is arranged corresponding to the rolling brush body 212, and the dust suction port 51 is arranged corresponding to and communicated with the dust collection port of the dust box. Specifically, the dust suction port 51 is arranged opposite to the V-shaped structure of the second rolling brush structure and the side position of the first rolling brush structure away from the fixed end 2120, so that the linear objects and other garbage cleaned by the rolling brush body 212 can enter the dust box along the dust suction port 51 and the dust collection port.

[0188] In the present embodiment, regardless of the structure of the rolling brush body 212, the present embodiment can increase the pitch of at least one of the first brush strip 2122 and the second brush strip 2123 to improve the cleaning efficiency and effect of the rolling brush body 212 on the linear objects and other garbage. The pitch refers to the axial distance between the corresponding two apexes of adjacent two spiral teeth of the first brush strip 2122 and the second brush strip 2123 on the median line (i.e. along the radial direction of the roller 2121). As shown in Figure 13 , the relative Figure 12 structure of the first brush strip 2122 and the second brush strip 2123 after the pitch is increased is shown.

[0189] As shown in Figure 2 and Figure 3As shown, when the rolling brush body 212 includes the roller 2121, the first brush strip 2122, and the second brush strip 2123, the flexible blocking piece 62 of the blocking structure 60 in this embodiment can further include a blocking ring 213. At this time, the blocking ring 213 includes at least two pieces. In the first direction, the at least two pieces of the blocking ring 213 are respectively arranged at the end portions of the opposite ends of the rolling brush body 212. The blocking ring 213 can further block the linear objects and other garbage from entering between the end portion (such as the fixed end 2120) of the rolling brush body 212 and the cooperating piece 112 (such as winding around the rotating piece 211 at the rotating piece 211), so as to avoid the end portion of the rolling brush body 212 from being wound around the linear objects and being blocked by other garbage. In the first direction, the projection outer contour of the first brush strip 2122 is located within the projection outer contour of the blocking ring 213. That is, the outer edge of the blocking ring 213 in the radial direction of the roller 2121 protrudes from the outer edge of the first brush strip 2122 in the radial direction of the roller 2121, thereby effectively improving the blocking effect of the blocking ring 213 on the linear objects and other garbage.

[0190] In combination Figure 5 It can be known that the projection outer contours of the first brush strip 2122 and the blocking ring 213 in this embodiment are both circular contours, and the blocking ring 213 and the rolling brush body 212 are coaxially arranged. The blocking ring 213 has a first diameter, and the first brush strip 2122 has a second diameter. The difference between the first diameter and the second diameter is not less than 0.2 mm and not greater than 1.5 mm. Within the difference range, while ensuring that the projection outer contour of the blocking ring 213 is larger than the projection outer contour of the first brush strip 2122, in the radial direction of the roller 2121, the outer periphery of the projection outer contour of the blocking ring 213 protrudes from the outer periphery of the projection outer contour of the first brush strip 2122, thereby further improving the blocking effect of the blocking ring 213 on the linear objects and other garbage. The difference between the first diameter and the second diameter can specifically include one of 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, or any other numerical value between the two endpoint values of 0.2 mm and 1.5 mm.

[0191] In addition, to avoid the frame plate 121 interfering with the blocking ring 213 in the second direction, in the first direction, the projection outer contour of the blocking ring 213 is located within the projection outer contour of the second brush strip 2123. That is, in the radial direction of the roller 2121, the size of the blocking ring 213 is smaller than the size of the second brush strip 2123, so as to ensure that the outer periphery of the blocking ring 213 does not exceed the outer periphery of the second brush strip 2123, and thus the frame plate 121 does not interfere with the blocking ring 213 rotating with the roller 2121.

[0192] The retaining ring 213, roller 2121, and first brush strip 2122 are integrally formed, meaning they can be manufactured using a single injection molding process, thereby reducing production costs and improving production efficiency for the roller brush cover assembly. Along the first direction, a first gap (e.g., ...) exists between the retaining ring 213 and the mating part 112. Figure 3 The gap is indicated by the symbol D. In this embodiment, the roller brush component 21 also includes a seal 214, which is connected to and fills the first gap with either the retaining ring 213 or the mating component 112. This ensures that linear objects and other debris do not enter between the end of the roller brush body 212 and the mating component 112 along the first gap, and do not interfere with the rotating component 211, thus reducing the risk of the roller brush component 21 stopping its rotation and improving the cleaning effect. Specifically, the seal 214 in this embodiment may include at least one of a sealing ring, a felt sealing block, a foam sealing block, or a flocked sheet. Specifically, the seal 214 may be fixedly connected to the retaining ring 213, so that the side of the seal 214 away from the retaining ring 213 is tangential to the mating component 112 and can rotate relative to the mating component 112 with the retaining ring 213. This prevents linear objects and other debris from entering the first gap. The side of the seal 214 closest to the mating part 112 can also be fixedly connected to the mating part 112. The side of the seal 214 closest to the retaining ring 213 is tangent to the retaining ring 213, allowing the retaining ring 213 and the rotating part 211 to rotate relative to the seal 214. This installation method can also prevent linear objects and other debris from entering the first gap and becoming entangled in the rotating part 211. Specifically, the seal 214 can be an annular sealing sheet structure, which at least seals the opposite sides of the rotating part 211 along the second direction and the side closest to the scraper 22 along the third direction.

[0193] Therefore, during the process of the roller brush body 212 rotating to clean the surface to be cleaned, linear objects will not get tangled on the ends of the roller brush body 212. Moreover, since the frame plate 121 does not interfere with the roller brush body 212 and the rotating part 211, and the end of the roller brush body 212 is provided with a retaining ring 213, and the first gap between the roller brush body 212 and the mating part 112 is filled with a seal 214, the linear objects will move along with other debris as the roller brush body 212 rotates, and will not move towards the ends of the roller brush body 212. Finally, the linear objects and other debris will be collected by the dust collection port or processed by other means such as cutting with blades or cleaning with comb teeth 23, so that the ends of the roller brush part 21 are free from linear objects (such as hair) getting tangled.

[0194] The rotating member 211 comprises a rotating shaft 2111 and a supporting structure 2112. The rotating shaft 2111 is connected with the rolling brush body 212, and at least partially located between the fixed end 2120 of the rolling brush body 212 and the bracket 12. The supporting structure 2112 is located between the fixed end 2120 and the bracket 12 and is sleeved on the rotating shaft 2111, and the supporting structure 2112 supports the rotating shaft 2111 in the second groove 1122 of at least one of the cooperating member 112 and the frame 11. The rotating shaft 2111 and the supporting structure 2112 are both spaced from the bracket 12 to avoid interference with the rotating shaft 2111 and the supporting structure 2112 during rotation of the bracket 12. Specifically, in the first direction, when the bracket 12 is the frame plate 121, the inner wall surfaces on the opposite sides of the first opening 1210 are both spaced from the rotating shaft 2111 and the supporting structure 2112. That is, the first swing arm 1212 and the second swing arm 1213 are both spaced from the rotating shaft 2111 and the supporting structure 2112, so that whether the first swing arm 1212 and the second swing arm 1213 of the bracket 12 are movable relative to the frame 11 or not, the bracket 12 and the first swing arm 1212 and the second swing arm 1213 thereof will not interfere with the rotating shaft 2111 and the supporting structure 2112, nor will they press the rolling brush body 212.

[0195] In the second direction, the first opening 1210 in this embodiment includes a first inner tangent surface 2101 and a second inner tangent surface 2102. The first inner tangent surface 2101 is the inner tangent surface of the first opening 1210 close to the scraping strip, and the first inner tangent surface 2101 and the second inner tangent surface 2102 are both tangent surfaces at the vertices closest to the center point of the rolling brush body 212 from the second opening. The first inner tangent surface 2101 is specifically a tangent surface at the vertex closest to the rolling brush body 212 in the second direction of the second connecting section 1214, and when the side close to the rolling brush body 212 of the second connecting section 1214 is a planar structure, the first inner tangent surface 2101 is the wall surface of the side close to the rolling brush body 212 of the second connecting section 1214. The second inner tangent surface 2102 is specifically a tangent surface at the vertex closest to the rolling brush body 212 in the second direction of the first connecting section 1211. Among them, at least one of the first inner tangent surface 2101 and the scraping strip 22 is in interference fit with the rolling brush body 212, and the first interference amount between at least one of the first inner tangent surface 2101 and the scraping strip 22 and the rolling brush body 212 is not greater than 2 mm. In this embodiment, by making the first interference amount not greater than 2 mm, the extrusion force of at least one of the first inner tangent surface 2101 and the scraping strip 22 on the opposite sides of the rolling brush body 212 is reduced, so that the linear object and other garbage can be more efficiently and quickly moved in the direction of the dust collecting port with the rotation of the rolling brush body 212, further improving the cleaning efficiency and effect of the rolling brush body 212 on the linear object and other garbage. When the first interference amount between the first inner tangent surface 2101 and the scraping strip 22 and the rolling brush body 212 is not greater than 2 mm, the cleaning efficiency is best. If the first inner tangent surface 2101 has a first distance from the axis of the rotating shaft 2111, the outer tangent surface of the rolling brush body 212 has a second distance from the axis of the rotating shaft 2111, and the difference between the second distance and the first distance is the first interference amount. Among them, when the size of the first brush strip 2122 is greater than the size of the second brush strip 2123, the outer tangent surface is the outer surface of the first brush strip 2122 in the radial direction of the rotating shaft 2111, and when the size of the first brush strip 2122 is smaller than the size of the second brush strip 2123, the outer tangent surface is the outer surface of the second brush strip 2123 in the radial direction of the rotating shaft 2111). The first interference amount can specifically include one of 2 mm, 1.9 mm, 1.8 mm, 1.7 mm, 1.5 mm, 1.3 mm, 1.2 mm, 1.0 mm, 0.8 mm, 0.6 mm, 0.5 mm, 0.3 mm, 0.1 mm, or any other value not greater than 2 mm.

[0196] In a preferred embodiment of the present application, at least one of the first inner surface 2101 and the scraping strip 22 is in clearance fit with the rolling brush body 212, that is, at least one of the first inner surface 2101 and the scraping strip 22 is not pressed to the opposite sides of the rolling brush body 212, and preferably both the first inner surface 2101 and the scraping strip 22 are in clearance fit with the rolling brush body 212, so that the linear objects and other garbage can be more efficiently and unobstructedly moved to the dust collection port along with the rotation of the rolling brush body 212, or moved to the other end or middle of the rolling brush body 212 for collection in other ways, so as to improve the cleaning efficiency.

[0197] In the second direction, at least one of the first inner surface 2101 and the scraping strip 22 has a second gap with the rolling brush body 212 (specifically with the outer surface of the rolling brush body 212, such as the outer surface of the first brush strip 2122 or the outer surface of the second brush strip 2123). As shown in the figure, in the process of rotating in the direction indicated by the arrow S, the linear objects and other garbage can be moved by the rolling brush body 212 to the second gap and then moved to the dust collection port in the first direction. In this process, while ensuring to improve the cleaning efficiency, it is avoided that part of the linear objects and other garbage may fall back from the second gap to the surface to be cleaned due to the second gap being too large, which affects the cleaning effect. Therefore, the second gap is set to be not greater than 2 mm in the present embodiment, and within this range, both the moving speed of the linear objects and other garbage is improved to improve the cleaning efficiency, and it is also ensured that the linear objects and other garbage will not fall back to the surface to be cleaned to improve the cleaning effect. The second gap can specifically include one of 2 mm, 1.9 mm, 1.8 mm, 1.7 mm, 1.6 mm, 1.4 mm, 1.2 mm, 1.1 mm, 0.9 mm, 0.8 mm, 0.5 mm, 0.4 mm, 0.2 mm, 0.1 mm, 0 mm, or any other numerical value not greater than 2 mm. Figure 5 Figure 5 In the process of rotating in the direction indicated by the arrow S, the linear objects and other garbage can be moved by the rolling brush body 212 to the second gap and then moved to the dust collection port in the first direction. In this process, while ensuring to improve the cleaning efficiency, it is avoided that part of the linear objects and other garbage may fall back from the second gap to the surface to be cleaned due to the second gap being too large, which affects the cleaning effect. Therefore, the second gap is set to be not greater than 2 mm in the present embodiment, and within this range, both the moving speed of the linear objects and other garbage is improved to improve the cleaning efficiency, and it is also ensured that the linear objects and other garbage will not fall back to the surface to be cleaned to improve the cleaning effect. The second gap can specifically include one of 2 mm, 1.9 mm, 1.8 mm, 1.7 mm, 1.6 mm, 1.4 mm, 1.2 mm, 1.1 mm, 0.9 mm, 0.8 mm, 0.5 mm, 0.4 mm, 0.2 mm, 0.1 mm, 0 mm, or any other numerical value not greater than 2 mm.

[0198] In the present embodiment, in order to further improve the cleaning efficiency of the linear objects and other garbage, when the second inner surface 2102 of the first opening 1210 is in interference fit with the rolling brush body 212, the interference amount between the second inner surface 2102 and the rolling brush body 212 is also not greater than 2 mm. Preferably, the second inner surface 2102 is in clearance fit with the rolling brush body 212, and in the second direction, the second inner surface 2102 has a third gap with the rolling brush body 212, and the third gap is not greater than 2 mm, so as to avoid that the second inner surface 2102 is pressed to the rolling brush body 212 while improving the cleaning efficiency.

[0199] ​The interference amount between the scraping strip 22 and the support 12 and the rolling brush body 212 in the embodiment is the same or slightly different. Here, in order to verify the influence of the first interference amount and the second gap on the hair winding condition and the cleaning effect of the rolling brush cover assembly, the interference amount between the first inner cutting surface 2101 and the second inner cutting surface 2102 of the scraping strip 22 and the support 12 and the rolling brush body 212 is set to be the same when the rolling brush cover assembly is tested and verified, and the values of the interference amount and the second gap are collectively referred to as the interference amount X, that is Figure 16 The abscissa in the figure represents the interference amount X obtained by testing, and the unit is mm (millimeter). When X>0, it is interference fit, and when X<0, it is gap fit.

[0200] Figure 16 The value of the ordinate Y1 in the figure is the weight (g) of the hair at both ends of the rolling brush part 21 / the total amount (g) of the hair used for the test test*100% (the symbol * in the embodiment is the multiplication symbol). The test condition of the value of Y1 is that 0.3g of hair is uniformly scattered on the ceramic tile floor with a fixed area of 1.6*1.6, and the rolling brush cover assembly installed on the cleaning equipment is naturally cleaned. After cleaning, it is processed back to the base station, and then it is continuously scattered in this way for a predetermined number of times, which is not less than 100 times. Finally, the hair at both ends of the rolling brush part 21 is weighed, and then Y1=the obtained weight / 0.3*100%.

[0201] Figure 16 The value of the ordinate Y2 in the figure is the calculated cleaning efficiency of one cleaning according to the requirement of QBT 4833-2015 / IEC 62885-7 when the cleaning equipment is operated in the cleaning mode. The test results are shown in Table 1:

[0202] X / mm Y1 Y2 -5 0 63.2％ -4 0 64.5％ -3 0 63.2％ -2 0 85.2％ -1 0 84.7％ 0 0 86.5％ 1 0 95.1％ 2 0 96.3％ 3 1.2％ 95.2％ 4 1.3％ 94.3％ 5 3.5％ 96.2％

[0203] Table 1

[0204] According to the test results in Table 1 above and Figure 16 It can be known that when Y1=0 and Y2≥85%, the value of the interference amount X is between-2mm and 2mm (the range is shown in the rectangular dashed box in Figure 16 ). When the interference amount test value is greater than 0 and not less than 2mm, that is, in the interference fit condition, the smaller the interference amount test value, the greater Y2, and the better the cleaning efficiency and cleaning effect. When the interference amount test value is not less than-2mm, that is, in the gap fit condition, the value of Y2 is greater than that in the interference fit condition, that is, the cleaning efficiency and effect are better when the gap fit.

[0205] The second embodiment of the present application also provides a cleaning device, which comprises a cleaning module. The specific structure of the cleaning module can be known from the content provided by the second embodiment of the present application, and will not be described here. The bottom of the cleaning device can be provided with a containing groove, and the cleaning module is buckled in the containing groove. The dust collection assembly and the driving mechanism can also be installed in the cleaning device. The dust collection assembly can comprise a dust box and an air suction member, and the dust box is located on the side of the containing groove away from the cleaning module. Please refer to Figures 18 to 21 The cleaning device also comprises a bottom shell 50 provided with a dust suction port 51. The dust suction port 51 is arranged between the dust collection port of the dust box and the roller brush body 212 of the cleaning module, so that the roller brush body 212 can move the garbage and linear objects to the dust suction port 51 to be collected by the dust box. The driving mechanism can specifically comprise a motor and a gear box and the like. The motor is installed in the mounting shell of the cleaning device and is in transmission connection with the gear box. The output shaft of the gear box is connected with the rotating piece 211. The motor drives the gear box to drive the rotating piece 211 to rotate, and the rotating piece 211 can also drive the roller brush body 212 to rotate. The cleaning module provided in the cleaning device of the present embodiment can improve the cleaning efficiency and effect of the cleaning device, and prolong the service life of the cleaning device.

[0206] The roller brush body 212 of the cleaning module has a V-shaped structure (the specific structure of the V-shaped structure can be known from the content provided by the second embodiment), and the dust suction port 51 is arranged opposite to the V-shaped structure. And / or, the roller brush body 212 comprises a first roller brush structure, and the dust suction port 51 is arranged opposite to the side of the first roller brush structure away from the fixed end 2120. Thus, the linear objects and other garbage gathered at the V-shaped structure and / or the side of the first roller brush structure away from the fixed end 2120 can be sucked into the dust box of the cleaning device in time through the dust suction port 51. The dust suction port 51 is arranged corresponding to and in communication with the dust collection port of the dust box, so that the linear objects and other garbage swept by the roller brush body 212 can enter the dust box through the dust suction port 51 and the dust collection port.

[0207] The rolling brush body 212 in the embodiment can include at least one of a first rolling brush structure and a second rolling brush structure, and the first rolling brush structure and the second rolling brush structure are each one or more. The first rolling brush structure is a rolling brush structure with one of the opposite ends being a fixed end 2120, and the second rolling brush structure is a rolling brush structure with both of the opposite ends being fixed ends 2120. Regardless of whether the rolling brush body 212 is the first rolling brush structure or the second rolling brush structure, since the cooperating part 112 is located between the fixed end 2120 and the support 12, the gap between the fixed end 2120 of the first rolling brush structure or the second rolling brush structure and the cooperating part 112 is not affected by the rotation of the support 12, and the linear object is not easy to enter between the fixed end 2120 of the first rolling brush structure or the second rolling brush structure and the cooperating part 112, thereby improving the operation stability of the first rolling brush structure and the second rolling brush structure. The rolling brush body 212 can be only one first rolling brush structure or one second rolling brush structure, or can be a combination of two coaxially arranged first rolling brush structures and second rolling brush structures, or a combination of four first rolling brush structures, or a combination of multiple second rolling brush structures, etc., which is not uniquely limited in the embodiment.

[0208] The cleaning module in the embodiment further includes an unwinding component, which can be installed between the rolling brush body 212 and the dust suction port 51, i.e., the unwinding component can be installed on the side of the bottom shell 50 close to the rolling brush body 212 and located between the rolling brush body 212 and the dust suction port 51, or the unwinding component can be installed on the rolling brush body 212 and arranged opposite to the dust suction port 51, so that the unwinding component can disperse and / or cut the linear object entering between the dust suction port 51, and then the linear object is collected by the dust suction port 51, thereby improving the collection effect of the dust suction port 51 on the linear object.

[0209] The unwinding component in the embodiment can be specifically installed at the V-shaped structure of the first brush strip 2122 and the second brush strip 2123. The unwinding component can cut and comb or cut the linear object (such as hair) gathered at the V-shaped structure, and the cut linear object is small and is easy to be collected by the dust collection port in the cleaning device. The unwinding component can be installed on the rolling brush component 21, or installed on the side of the bottom shell 50 close to the rolling brush body 212 and arranged opposite to the V-shaped structure. The unwinding component in the embodiment can include at least one of a comb tooth 23 and a cutting blade. Figure 12 As shown in the figure, if the unwinding component is the comb tooth 23, the bottom of the comb tooth 23 can be connected with the outer side wall of the rotating shaft 2111, and the part of the comb tooth 23 away from the rotating shaft 2111 penetrates the rolling drum 2121 and is located at the V-shaped structure along the radial direction of the rotating shaft 2111, so that the linear object moving to the V-shaped structure will be cut and combed by the comb tooth 23, thereby being more efficiently collected by the dust collection port.
