Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, in particular to a rolling brush assembly, a cleaning equipment and a cleaning system. BACKGROUND

[0002] The existing cleaning equipment, such as scrubber and the like, usually adopts a motor to drive a roller to rotate, so as to drive a cleaning member connected outside the roller to rotate to clean the ground. During long-term cleaning use, the cleaning member may be partially hardened and damaged, so that the effective cleaning area of the cleaning member is reduced, the cleaning capacity is reduced, and the like, resulting in poor ground cleaning degree, more residual water stains and stains.

[0003] In the prior art, the entire rolling brush assembly is usually replaced to improve the cleaning capacity, but the use and maintenance cost is high. Alternatively, the cleaning member connected to the surface of the roller is replaced or the roller is directly replaced, but when the cleaning member is replaced or the roller is replaced, the disassembly and assembly of the rolling brush assembly is relatively cumbersome, more components need to be disassembled and assembled, which may cause misdisassembly, the assembly cost is high, the installation is difficult and time-consuming, and the user is not convenient when disassembling the rolling brush assembly, which affects the user experience. UTILITY MODEL CONTENT

[0004] Therefore, the present disclosure aims to at least solve one of the technical problems in the prior art; the present disclosure provides a rolling brush assembly, a cleaning equipment and a cleaning system, which aims to realize quick and convenient disassembly and assembly of the rolling brush assembly, simple disassembly and assembly steps, less disassembly and assembly components, which is not easy to cause misdisassembly, the rolling brush assembly disassembled from the machine body can be separately disassembled and assembled with the roller, which saves cost, and can improve the user experience.

[0005] The first aspect of the present disclosure provides a roller brush assembly applied to a cleaning device, the cleaning device comprising a machine body, the roller brush assembly being detachably mounted to the machine body and comprising a mounted state and a detached state, the mounted state being a state in which the roller brush assembly is mounted to the machine body, and the detached state being a state in which the roller brush assembly is detached from the machine body; wherein a direction in which the roller brush assembly is mounted to the machine body is a mounting direction, and a direction in which the roller brush assembly is detached from the machine body is a detachment direction, the mounting direction being opposite to the detachment direction; the roller brush assembly comprises a roller and a support arm; along an axial direction of the roller, the roller comprises a driving end and a supporting end, the driving end of the roller being detachably connected with the machine body; the support arm extends along a radial direction of the roller, the support arm comprising a first supporting part and a second supporting part, in the extension direction of the support arm, the first supporting part is closer to the roller than the second supporting part, the first supporting part is detachably connected with the supporting end of the roller, and the second supporting part is detachably connected with the machine body; when the roller brush assembly is in the mounted state and a first external force acts on the support arm, the frictional force between the first supporting part and the supporting end of the roller in the axial direction of the roller is greater than the frictional force of the driving end of the roller being detached from the machine body, so that the roller brush assembly as a whole can be detached from the machine body, wherein the first external force has a component force at least in the detachment direction.

[0006] The roller brush assembly provided by the first aspect of the present disclosure can be used in a cleaning device. The driving end of the roller brush assembly is detachably connected with the machine body, and the supporting end of the roller brush assembly is detachably connected with the machine body through the second supporting part. When the roller brush assembly used for cleaning the ground needs to be removed, a first external force is applied to the support arm. When the component force of the first external force in the detachment direction is greater than the frictional force of the driving end of the roller being detached from the machine body, the driving end of the roller can be separated from the machine body first, and then the entire roller brush assembly can be detached from the machine body. At this time, since the frictional force between the first supporting part of the support arm and the supporting end of the roller in the axial direction of the roller is greater than the frictional force of the driving end of the roller being detached from the machine body, the first supporting part and the supporting end of the roller still remain connected, so that the entire roller brush assembly can be conveniently detached from the machine body without the need to detach many parts, and the operation is extremely simple. The detached roller brush assembly can clean the surface of the roller. The first supporting part and the supporting end of the roller can also be detached by further applying a force, so that the support arm and the roller are separated, and then a roller with a damaged surface cleaning element or low cleaning efficiency can be replaced, and the replacement step is simple, without the need to replace the entire roller brush assembly, thereby saving costs.

[0007] The second aspect of the present disclosure provides a roller brush assembly applied to a cleaning device, the cleaning device comprising a machine body, the roller brush assembly being detachably mounted to the machine body and comprising a mounted state and a detached state, the mounted state being a state in which the roller brush assembly is mounted to the machine body, and the detached state being a state in which the roller brush assembly is detached from the machine body; wherein a direction in which the roller brush assembly is mounted to the machine body is a mounting direction, and a direction in which the roller brush assembly is detached from the machine body is a detachment direction, the mounting direction being opposite to the detachment direction; the roller brush assembly comprises a roller and an arm; along an axial direction of the roller, the roller comprises a driving end and a supporting end, the driving end of the roller being detachably connected to the machine body; the arm extends along a radial direction of the roller, the arm comprising a first supporting part and a second supporting part, in the extension direction of the arm, the first supporting part is closer to the roller than the second supporting part, the first supporting part is detachably connected to the supporting end of the roller, and the second supporting part is detachably connected to the machine body; when the roller brush assembly is in the mounted state and a third external force acts on different positions of the arm, the friction between the first supporting part and the supporting end of the roller is different, so that under the action of the third external force, the roller brush assembly as a whole can be detached from the machine body or the arm can be detached from the roller, wherein the third external force has a component force in the detachment direction.

[0008] The roller brush assembly provided by the second aspect of the present disclosure can be used in a cleaning device. The driving end of the roller brush assembly is detachably connected to the machine body, and the supporting end of the roller brush assembly is detachably connected to the machine body through the second supporting part. By applying a third external force to different positions of the arm, different frictional forces between the first supporting part and the supporting end of the roller can be obtained when the component force of the third external force in the detachment direction is different. When the frictional force between the first supporting part and the supporting end of the roller is less than the component force of the third external force in the detachment direction, the first supporting part is detached relative to the roller, so that the arm and the roller are detached. When the frictional force between the first supporting part and the supporting end of the roller is greater than the component force of the third external force in the detachment direction, the first supporting part remains connected to the roller. At this time, if the component force of the third external force in the detachment direction is greater than the frictional force between the driving end of the roller and the machine body, the roller brush assembly as a whole can be detached from the machine body, which is convenient to operate.

[0009] The third aspect of the present disclosure provides a cleaning device comprising a machine body and the roller brush assembly of any of the preceding examples, the roller brush assembly being detachably connected to the machine body and being rotatable relative to the machine body.

[0010] The cleaning device provided in the third aspect of the present disclosure is provided with the rolling brush assembly described above, and rotation of the rolling brush assembly relative to the machine body realizes cleaning of the surface to be cleaned. When the rolling brush assembly needs to be replaced, an external force can be applied to quickly separate the rolling brush assembly from the machine body, facilitating maintenance. After the rolling brush assembly is detached from the machine body, an external force can be applied to quickly separate the roller and the supporting arm, facilitating replacement of the roller.

[0011] The fourth aspect of the present disclosure provides a cleaning system, which comprises a base station and the cleaning device of the foregoing examples, and the base station is used for maintaining the cleaning device.

[0012] The cleaning system provided in the fourth aspect of the present disclosure can realize quick decontamination of the cleaning device by matching the cleaning device with the base station, so that the cleaning device can be maintained daily and the service life of the cleaning device can be prolonged.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present disclosure will be clearly and completely described in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present disclosure.

[0040] It should also be understood that the terms used in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. As used in the specification and the appended claims of the present disclosure, the singular forms "a", "an" and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0041] It should be further understood that the term "and / or" used in the specification and the appended claims of the present disclosure refers to any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0042] Some embodiments of the present disclosure will be described in detail with reference to the drawings. The following embodiments and features of the embodiments described below can be combined with each other in the case of no conflict.

[0043] The present disclosure proposes a rolling brush assembly 100, which can be used in a cleaning device 1000.

[0044] The cleaning device 1000 can be an active cleaning device, which is a cleaning device that can move forward or backward, turn, and move to a surface to be cleaned autonomously. Such an active cleaning device has intelligent functions and can automatically adjust the cleaning path according to environmental changes. The degree of appropriateness of the cleaning path depends on the degree of intelligence of the device. The active cleaning device realizes automatic navigation, obstacle recognition, and cleaning path planning through built-in sensors, algorithms, and control systems, etc., thereby completing the cleaning task. For example, a robot vacuum cleaner senses the environment through built-in sensors, plans the best cleaning path using a navigation system, and completes the cleaning of the ground through functions such as dust collection and / or sweeping and / or mopping. Such an active cleaning device can automatically avoid obstacles and avoid cleaning areas that have already been cleaned, thereby improving cleaning efficiency and quality. The active cleaning device includes but is not limited to a robot vacuum cleaner, a robot dust collector, a robot sweeper and mop, a robot window cleaner, etc. Correspondingly, the surface to be cleaned can be a ground surface, a wall surface, a surface of a window, a bed surface, etc.

[0045] The cleaning device 1000 can also be a passive cleaning device, which is a cleaning device that needs to be moved to a surface to be cleaned by a user for cleaning. Such a device usually has a hand-held part, and the user needs to hold the hand-held part of the cleaning device and push the rolling brush of the cleaning device to move on the surface to be cleaned to clean the surface to be cleaned. The passive cleaning device includes but is not limited to a hand-held floor cleaner, a hand-held dust collector, or a hand-held mite remover, etc. Correspondingly, the surface to be cleaned can be a ground surface, a wall surface, a surface of a window, a bed surface, etc.

[0046] Since the cleaning equipment 1000 cleans the surface to be cleaned using the roller brush assembly 100, and to improve cleaning efficiency, the roller brush assembly 100 is typically a long, narrow component. During long-term cleaning of the surface, the surface of the roller brush assembly 100 will wear down and require replacement. Therefore, a convenient disassembly method is needed to quickly remove the roller brush assembly 100 from the cleaning equipment 1000. However, existing solutions require disassembly of numerous components, which can easily lead to accidental disassembly, and the operation steps for removing the roller brush assembly from the machine body are very cumbersome. Replacing the entire disassembled roller brush assembly 1000 typically results in high maintenance costs. In addition, if the roller brush assembly 100 is designed to be detachable, the existing disassembly scheme has the problems of inconvenience in disassembly and easy to cause accidental disassembly. For example, when removing the roller brush assembly 100 from the cleaning equipment 1000, due to improper application of force by the user, improper disassembly force, or design defects of the roller brush assembly 100 itself, the roller brush assembly 100 may not be completely removed from the cleaning equipment 1000, but the roller brush assembly 100 itself may be disassembled into several parts. In this case, the user may need to manually remove the parts that have not been removed (e.g., dirty rollers), which seriously affects the user experience.

[0047] This disclosure provides a roller brush assembly 100 that can solve at least one of the above-mentioned technical problems, and is applied to a cleaning device 1000, such as... Figure 1 and Figure 2 As shown, the cleaning equipment 1000 includes a body 200.

[0048] Please refer to Figure 1 and Figure 2 The roller brush assembly 100 is detachably mounted to the body 200, and includes both mounted and detached states, such as... Figure 1 As shown, the installation state is when the roller brush assembly 100 is installed onto the body 200, as... Figure 2 As shown, the disassembly state is the state in which the roller brush assembly 100 is detached from the body 200; wherein, the direction in which the roller brush assembly 100 is installed onto the body 200 is the installation direction (e.g., Figure 1 Or, in option 2, the axial direction of the roller brush assembly 100 is from right to left), and the direction in which the roller brush assembly 100 is removed from the body 200 is the removal direction (e.g., Figure 1 Or the axial direction of the roller brush assembly 100 in 2 is from left to right), and the installation direction is opposite to the disassembly direction.

[0049] refer to Figure 4 , Figure 10 , Figure 20 and Figure 21 As shown, the roller brush assembly 100 includes a roller 10 and a support arm 20. Along the axial direction of the roller 10, the roller 10 includes a drive end 11 and a support end 12, wherein the drive end 11 of the roller 10 and the support end 12... Figure 1The illustrated body 200 is detachably connected. The detachable connection here includes, but is not limited to, one or a combination of snap connection, plug-in connection, plug and socket connection, or bolt connection, etc.

[0050] As shown in Figure 3 , Figure 9 , Figure 20 and Figure 21 , the arm 20 extends in the radial direction of the roller 10. As shown in Figure 5 , Figure 11 , Figure 15 , the arm 20 includes a first support portion 21 and a second support portion 22, the first support portion 21 is closer to the roller 10 than the second support portion 22 in the extension direction of the arm 20, the first support portion 21 is detachably connected with the support end 12 of the roller 10, and the second support portion 22 is detachably connected with the body 200. Here, the detachable connection between the first support portion 21 and the support end 12 of the roller 10 includes, but is not limited to, one or a combination of snap connection, plug-in connection, bolt connection, etc. Similarly, the detachable connection between the second support portion 22 and the body 200 includes, but is not limited to, one or a combination of snap connection, plug-in connection, bolt connection, etc.

[0051] When the roller brush assembly 100 is in the mounted state and the first external force acts on the arm 20, the frictional force between the first support portion 21 and the support end 12 of the roller 10 in the axial direction of the roller 10 is greater than the frictional force of the drive end 11 of the roller 10 from the body 200, so that the entire roller brush assembly 100 can be detached from the body 200, wherein the first external force has a component in the detachment direction. Exemplarily, the detachment direction can be parallel to the axial direction of the roller 10 and point from the drive end 11 to the support end 12.

[0052] The roller brush assembly 100 disclosed in the present disclosure can be used in a cleaning device 1000. The drive end 11 of the roller brush assembly 100 is detachably connected with the body 200, and the support end 12 of the roller brush assembly 100 is detachably connected with the body 200 through the second support portion 22. When the roller brush assembly 100 needs to be detached from the body 200, a first external force is applied to the arm 20, and when the component of the first external force in the detachment direction is greater than the frictional force of the drive end 11 of the roller 10 from the body 200, and at the same time, the frictional force between the first support portion 21 and the support end 12 of the roller 10 in the axial direction of the roller 10 is greater than the frictional force of the drive end 11 of the roller 10 from the body 200, the drive end 11 of the roller 10 can be separated from the body 200 first, and then the entire roller brush assembly 100 can be detached from the body 200.

[0053] At this time, since the friction between the first supporting part 21 of the supporting arm 20 and the supporting end 12 of the roller 10 in the axial direction of the roller 10 is greater than the friction of the driving end 11 of the roller 10 from the machine body 200, the first supporting part 21 can always be connected with the supporting end 12 of the roller 10 when the driving end 11 and the machine body 200 are disassembled, so that the entire roller brush assembly 100 can be conveniently disassembled from the machine body 200 without the need to disassemble many parts, and it is not easy to disassemble by mistake, and the operation is extremely simple.

[0054] The roller brush assembly 100 disassembled from the machine body 200 can clean the surface of the roller 10. The first supporting part 21 can be disassembled from the supporting end 12 of the roller 10 by further applying force to the supporting arm 20, so that the supporting arm 20 is separated from the roller 10, and the roller 10 with a damaged surface cleaning part and low cleaning efficiency is replaced, and the replacement operation steps are simple, and compared with the replacement of the entire roller brush assembly 100, the cost is saved.

[0055] It can be understood that, compared with the prior art, when the roller brush assembly is disassembled from the machine body, many parts need to be disassembled, which is easy to cause disassembly by mistake; and the disassembled roller brush assembly needs to be replaced with a new roller brush assembly to realize maintenance, which is high in cost; the above-mentioned roller brush assembly 100 of the present disclosure does not need to disassemble many parts, but realizes one-step disassembly by applying force to the supporting arm 20, so that the entire roller brush assembly 100 can be quickly disassembled from the machine body 200, which is convenient and fast and not easy to disassemble by mistake. In addition, the above-mentioned roller brush assembly 100 of the present disclosure does not need to replace the entire roller brush assembly 100, but only needs to separate the roller 10 and the supporting arm 20, replace the roller 10 with a damaged surface, and the supporting arm 20 can still be reused, and the supporting arm 20 can be reconnected with a new roller 10, which saves the cost of maintenance and improves the user experience. Furthermore, the above-mentioned roller brush assembly 100 of the present disclosure is more convenient to disassemble and assemble, the disassembly and assembly steps are simple, time and labor are saved, and it can be disassembled and assembled as needed and is not easy to disassemble by mistake.

[0056] In some embodiments, as Figure 3 , Figure 9 , Figure 20 and Figure 21As shown, the position where the first external force acts on the support arm 20 is in the extension direction of the support arm 20, the farther away from the first support part 21, the greater the friction between the first support part 21 and the support end 12 of the roller 10 in the axial direction of the roller 10. The first support part 21 is closer to the roller 10, and when the force acting on the support arm 20 is farther away from the first support part 21, the force arm is longer, and the component force in the disassembly direction generated by the same acting force will be smaller, and then, if the friction between the first support part 21 and the support end 12 is to be overcome to separate the two, a greater first external force must be applied to the support arm 20. The position where the first external force acts on the support arm 20 is in the extension direction of the support arm 20, the farther away from the first support part 21, the more difficult to disassemble the first support part 21 and the support end 12, but to separate the driving end 11 from the machine body 200, so as to disassemble the roller brush assembly 100 from the machine body 200 as a whole.

[0057] In some embodiments, as shown in Figure 4 、 Figure 10 、 Figure 19 、 Figure 20 and Figure 21 , the support arm 20 further comprises a hand 23 for the user to hold to disassemble the roller brush assembly 100 from the machine body 200 as a whole, and the hand 23 is connected with the second support part 22. By providing the hand 23, it is convenient for the user to apply force and hold, and the force applied to the hand 23 can be quickly transmitted to the second support part 22, and then transmitted to the first support part 21 by the second support part 22, and then transmitted to the entire roller 10 through the first support part 21, so that when the resultant force at the detachable part is sufficient to cause the two detachable parts to move relative to each other, the two detachable parts can be separated.

[0058] Optionally, in the radial direction of the roller 10, the hand 23 is located outside the diameter range of the roller 10. That is, the projection of the hand 23 on the plane where the support end 12 of the roller 10 is located is located outside the plane of the support end 12. The hand 23 is convenient for the user to apply the first external force, so that when the hand 23 at this position is forced, the friction between the first support part 21 and the support end 12 of the roller 10 in the axial direction of the roller 10 is greater than the friction between the driving end 11 and the machine body 200, and the first support part 21 and the roller 10 are not easy to separate when forced; and the friction of the driving end 11 from the machine body 200 can be more easily overcome by the first external force applied to the hand 23, so as to realize the disassembly of the driving end 11 and the machine body 200, and then disassemble the roller brush assembly 100 from the machine body 200 as a whole.

[0059] And / or, the first end of the hand 23 is rotationally connected with the second support part 22, the second end of the hand 23 extends to the end of the second support part 22 along the radial direction of the roller 10 and contacts the end of the second support part 22 connected with the machine body 200, so that the user can pull the hand 23 at this position to apply force, and the hand 23 does not interfere with the connection between the second support part 22 and the machine body 200.

[0060] Optionally, as shown in Figure 4 , Figure 10 , Figure 19 , Figure 20 and Figure 21 , the second support part 22 is provided with a rotating shaft 221, and the hand 23 is connected with the rotating shaft 221 and rotationally connected with the second support part 22 through the rotating shaft 221. Then, the second support part 22 is rotationally connected with the hand 23 through the rotating shaft 221, so that the hand 23 is always connected with the second support part 22 together. When force needs to be applied to the support arm 20, the hand 23 can be pulled by fingers and rotated, and force can be applied on the hand 23, such as pulling the hand 23. Exemplarily, the hand 23 is U-shaped, and after the hand 23 is pulled around the rotating shaft 221, the hand 23 can be held by fingers and force can be applied.

[0061] Optionally, as shown in Figure 8 , Figure 14 , Figure 19 , Figure 21 , a torsional spring 231 is sleeved on the rotating shaft 221, one end of the torsional spring 231 is connected with the second support part 22, and the other end of the torsional spring 231 is connected with the hand 23. When the rotating shaft 221 rotates by a certain angle, the torsional spring 231 deforms and stores energy, and the torsional spring 231 has the effect of driving the rotating shaft 221 to rotate back to the original position, so as to facilitate the resetting of the hand 23, and further facilitate the hand 23 to remain in the extension direction of the second support part 22, that is, to remain in the radial direction of the roller 10. When the applied first external force disappears, the torsional spring 231 drives the hand 23 to reset, facilitating the next time force application; the hand 23 can also be stored close to the machine body 200 side to prevent the hand 23 from hanging foreign matter.

[0062] Optionally, the end of the first support part 21 away from the support end 12 is connected with the second support part 22, so that when the second support part 22 is connected with the machine body 200, the roller 10 connected with the first support part 21 is also fixed relative to the machine body 200.

[0063] In some embodiments, as shown in Figure 4 , Figure 10 , Figure 20 and Figure 21As shown, the support end 12 of the roller 10 further comprises a mounting cavity 121, the first support part 21 comprises a rotating seat 24 and a connecting end 25, and the rotating seat 24 is rotationally connected with the connecting end 25. That is, the connecting end 25 is closer to the second support part 22 relative to the rotating seat 24, and the connecting end 25 can be directly connected with the second support part 22 (for example, the two can be integrally connected, see Figure 10 ), or indirectly connected with the second support part 22 (for example, the two are connected through other components, see Figure 4 ); and the rotating seat 24 can rotate relative to the connecting end 25 and the second support part 22.

[0064] Further, when the support arm 20 is connected with the roller 10, at least part of the rotating seat 24 is located in the mounting cavity 121, and the outer wall of the at least part of the rotating seat 24 located in the mounting cavity 121 is adapted to the mounting cavity 121. That is, at least part of the rotating seat 24 is sleeved in the mounting cavity 121, the opposite surfaces of the two have a certain contact area, and the rotating seat 24 and the mounting cavity 121 form radial limiting, so that the rotating seat 24 is as stably connected in the mounting cavity 121 as possible; at the same time, the installation depth of the rotating seat 24 in the mounting cavity 121 also makes the connection between the support arm 20 and the roller 10 have a certain length, so as to ensure that the support arm 20 can always keep stable connection with the roller 10 without being separated from the roller 10 when the roller brush assembly 100 rotates relative to the machine body 200 under the condition that no first external force is applied to the support arm 20 after the support arm 20 is connected to the roller 10, and the roller brush assembly 100 can continuously and reliably work.

[0065] Optionally, the axial extension length of the rotating seat 24 relative to the roller 10 is 5% to 15% of the axial length of the roller 10. By limiting the length of the rotating seat 24, the rotating seat 24 and the roller 10 can have sufficient matching area to form stable contact; and the length of the rotating seat 24 along the axial direction of the roller 10 can be reasonably designed, the processing cost can be controlled, the weight of the rotating seat 24 as a whole can be controlled within a certain range of the weight of the roller brush assembly 100, the roller brush assembly 100 can be relatively light, and the roller 10 has more installation space to integrate other components.

[0066] For example, in some specific examples, the length of the rotating seat 24 is 25 mm, and the length of the roller 10 is 255 mm, and the length ratio of the two is 1:9.8.

[0067] Optionally, as Figure 4 , Figure 20 and Figure 21As shown, the diameter of the connecting end 25 is equal to the diameter of the rotating seat 24, and both are smaller than the inner diameter of the barrel of the supporting end 12 of the drum 10. In these examples, at least part of the connecting end 25 is exposed at one end of the drum 10 and covers the rotating seat 24 inside the drum 10, so that the rotating seat 24 is not easy to be covered with dust; the diameters of both the connecting end 25 and the rotating seat 24 are smaller than the inner diameter of the barrel of the supporting end 12, so that the connecting end 25 and the rotating seat 24 can be fitted into the supporting end 12, preventing the first supporting part 21 from protruding too much outward from the drum 10, and making the fitting structure of the supporting arm 20 and the drum 10 more compact. In these examples, the connecting end 25 can be regarded as an end cover fitted on the supporting end 12 of the drum 10.

[0068] For example, the rotating seat 24 can be entirely arranged in the mounting cavity 121, or partially arranged in the mounting cavity 121 and the rest arranged outside the mounting cavity 121; the connecting end 25 can be partially arranged in the mounting cavity 121 or entirely arranged outside the mounting cavity 121; the present application does not make specific limitation on the above structure arrangement, which can be arranged according to requirements.

[0069] Optionally, as shown in Figure 10 , Figure 15 the diameter of the connecting end 25 is smaller than the diameter of the rotating seat 24, and the diameter of the rotating seat 24 is smaller than the inner diameter of the barrel of the supporting end 12 of the drum 10; in these examples, at least part of the outer wall of the rotating seat 24 is in contact with the inner wall of the supporting end 12, while the outer wall of the connecting end 25 is not in contact with the supporting end 12, so that the outer end surface of the rotating seat 24 close to the connecting end 25 can be exposed, and thus force can be directly applied on the rotating seat 24. Further components can be arranged on the rotating seat 24, such as the unlocking member 50 described later or the acting member 40 described later, to facilitate the hand to directly apply force. In these examples, the end part of the rotating seat 24 and the connecting end 25 together enclose the supporting end 12 of the drum 10, effectively preventing dust and debris from entering the inside of the drum 10.

[0070] In some examples, as shown in Figure 6 , Figure 12 and Figure 16As shown, the first support part 21 also includes a rotating shaft 211 and a bearing component 212. The rotating shaft 211 is arranged perpendicular to the plane where the connecting end 25 is located and passes through the geometric center of the connecting end 25. One end of the rotating shaft 211 is connected to the connecting end 25, and the other end of the rotating shaft 211 passes through the bearing component 212. The bearing component 212 is rotatably connected to the rotating shaft 211. The rotating seat 24 is provided with the bearing component 212 between it and the connecting end 25, and the rotating seat 24 is connected to the bearing component 212. When the rotating seat 24 is installed in the mounting cavity 121, the roller brush assembly 100 rotates. When in motion, the roller 10 and the rotating seat 24 can rotate relative to the rotating shaft 211, and the axis of the rotating shaft 211 can also be regarded as the rotation axis of the roller brush assembly 100. When the second support 22 is connected to the machine body 200 and the drive end 11 of the roller 10 is connected to the machine body 200 (for example, the drive end 11 is connected to a motor provided on the machine body 200, wherein the motor extends into the inner cavity of the drive end 11 and is connected to the corresponding structure in the inner cavity), the roller brush assembly 100 can rotate stably with the axis of the rotating shaft 211 as the rotation axis.

[0071] In this disclosure, the first support part 21 is detachably connected to the support end 12 of the roller 10, and can be one or a combination of snap-fit ​​connection, plug-in connection, bolt connection.

[0072] For example, it can be like Figure 20 The roller 10 and support arm 20 shown are connected by fasteners 71. One of the rotating base 24 and the support end 12 of the roller 10 is provided with a stud 72, and the other with a mounting hole 73. Fasteners 71, such as bolts, pass through the mounting hole 73 and connect to the stud 72, thereby connecting the rotating base 24 and the support end 12. In some specific examples, to facilitate manual force application, such as... Figure 20 As shown, a mounting hole 73 is provided on the rotating base 24, extending along the axial direction of the roller 10, and a stud 72 is provided on the support end 12 corresponding to the mounting hole 73. When the rotating base 24 is inserted into the mounting cavity 121 of the support end 12, the mounting hole 73 and the stud 72 are aligned, and the fastener 71, such as a bolt, passes through the mounting hole 73 and is installed into the stud 72. When it is necessary to disassemble the support arm 20 and the roller 10, it is only necessary to remove the fastener 71 and apply external force to the support arm 20 to pull it away from the roller 10. In these examples, such as Figure 20 As shown, the outer wall of the rotating seat 24 can be provided with a relief groove 74 corresponding to the stud 72. The groove wall of the relief groove 74 fits with the outer wall of the stud 72, and the top of the relief groove 74 communicates with the assembly hole 73. During the assembly process, the stud 72 moves along the relief groove 74 and docks with the assembly hole 73. The relief groove 74 can guide the stud 72 and the assembly hole 73, and can also make the stud 72 fit tightly with the rotating seat 24.

[0073] For example, it can be like... Figure 21The roller 10 and the support arm 20 are inserted as shown in the figure, one of the rotating seat 24 and the support end 12 of the roller 10 is provided with an insertion buckle 81, and the other is provided with an insertion slot 82. When the insertion buckle 81 is inserted into the insertion slot 82, the connection of the rotating seat 24 and the support end 12 is realized. In some specific examples, as shown in Figure 21 the insertion slot 82 can be provided on the rotating seat 24, and the insertion buckle 81 can be provided on the support end 12 of the roller 10. When the rotating seat 24 is inserted into the mounting cavity 121 of the support end 12, the insertion buckle 81 is inserted into the insertion slot 82 to realize assembly. When disassembly is required, the insertion buckle 81 and the insertion slot 82 are separated by applying an external force on the support arm 20, so that the rotating seat 24 and the roller 10 can be disassembled.

[0074] For another example, the roller 10 and the support arm 20 can also be connected by clamping. The specific structure of the clamping connection of the roller 10 and the support arm 20 in the present disclosure will be described in detail below.

[0075] As shown in Figure 6 , Figure 12 and Figure 16 , one of the rotating seat 24 and the support end 12 of the roller 10 is provided with a clamping piece 30, and the other is provided with an acting piece 40. The clamping piece 30 and the acting piece 40 are detachably connected. By connecting the clamping piece 30 and the acting piece 40, the rotating seat 24 can be connected in the support end 12. The detachable design facilitates the application of force on the support arm 20 to separate the clamping piece 30 and the acting piece 40, so that the rotating seat 24 and the support end 12 are quickly separated, and the support arm 20 and the roller 10 are disassembled. Similarly, when installation is required, the clamping piece 30 and the acting piece 40 are clamped and connected by applying force on the support arm 20, so that the rotating seat 24 and the support end 12 are connected, and the support arm 20 and the roller 10 are quickly installed.

[0076] Further, the roller brush assembly 100 has a first state and a second state. In the first state, the clamping piece 30 and the acting piece 40 are connected, and in the second state, the clamping piece 30 and the acting piece 40 are separated. Then, the clamping piece 30 and the acting piece 40 have alternative states, either connected or separated. In different states, the connection relationship and position relationship of the clamping piece 30 and the acting piece 40 are different. The roller 10 and the support arm 20 of the roller brush assembly 100 in the first state are in a connected state, and the roller 10 and the support arm 20 of the roller brush assembly 100 in the second state are in a separated state.

[0077] Further, one of the engaging member 30 and the acting member 40 can move relative to the other, and has a first position and a second position. In the first state, the one of the engaging member 30 and the acting member 40 that can move relative to the other (i.e. the one that can move relative to the other) is in the first position, and the engaging member 30 is connected with the acting member 40; in the second state, the one of the engaging member 30 and the acting member 40 that can move relative to the other is in the second position, and the engaging member 30 is disconnected from the acting member 40. That is, when one of the engaging member 30 and the acting member 40 changes from the first position to the second position, the engaging member 30 and the acting member 40 change from the connected state to the disconnected state, which provides a basis for the separation of the support arm 20 and the roller 10, and facilitates the replacement of the roller 10.

[0078] In some embodiments, in combination with Figure 5 and Figure 6 As shown in the drawings, the engaging member 30 includes opposite first fixed end 31 and first free end 32, and the acting member 40 includes opposite second fixed end 41 and second free end 42. The first fixed end 31 is connected to one of the rotating seat 24 and the support end 12 of the roller 10, the second fixed end 41 is connected to the other of the rotating seat 24 and the support end 12 of the roller 10, and the first free end 32 is engaged with the second free end 42. Exemplarily, the first free end 32 and the second free end 42 each have a certain elastic deformation force, which facilitates engagement. Here, the first fixed end 31 and the second fixed end 41 can be fixed relative to the rotating seat 24 or the support end 12, so that when the position of the rotating seat 24 relative to the support end 12 changes, the first free end 32 and the second free end 42 form engagement or disengagement. After the first free end 32 and the second free end 42 are engaged, the rotating seat 24 is connected with the support end 12; after the first free end 32 and the second free end 42 are disengaged, the rotating seat 24 is separated from the support end 12. Exemplarily, the first fixed end 31 and the first free end 32 are opposite ends, and the second fixed end 41 and the second free end 42 are opposite ends.

[0079] and / or, as Figure 6As shown, the engaging member 30 comprises a first surface 33, the acting member 40 comprises a second surface 43, the first surface 33 and the second surface 43 are correspondingly arranged, and the included angle between the direction in which the first surface 33 and the second surface 43 extend towards the central axis of the roller 10 and the direction in which the central axis of the roller 10 points from the support end 12 to the driving end 11 is an acute angle, and the first surface 33 and the second surface 43 are in sliding fit during the switching between the first state and the second state. Then in these examples, the sliding fit of the first surface 33 and the second surface 43 can form a certain guiding effect, so that the acting member 40 and the engaging member 30 can form a smooth relative sliding; during the switching between the first state and the second state of the roller brush assembly 100, the engaging member 30 and the acting member 40 can be stably connected after the sliding fit of the first surface 33 and the second surface 43, or can be stably separated after the sliding fit of the first surface 33 and the second surface 43.

[0080] Exemplarily, the included angle between the direction in which the first surface 33 and the second surface 43 extend towards the central axis of the roller 10 and the direction in which the central axis of the roller 10 points from the support end 12 to the driving end 11 is an acute angle, and the angle of the acute angle can be in the range of 30 degrees to 60 degrees, for example, can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, etc.

[0081] And / or, referring to Figure 6 And 8 As shown, the rotating seat 24 provided with the acting member 40 or the support end 12 of the roller 10 is further provided with an opening 241, the position of the opening 241 corresponds to the position of the acting member 40, during the switching from the second state to the first state, the engaging member 30 is connected with the acting member 40 after passing through the opening 241, and during the switching from the first state to the second state, the engaging member 30 passes out of the opening 241 after being separated from the acting member 40. The opening 241 not only can make the engaging member 30 align with the acting member 40, and play a certain positioning role, but also can strengthen the structure of the rotating seat 24 provided with the acting member 40 or the structure of the roller 10 at the position of the acting member 40.

[0082] In some specific examples, as Figure 6 As shown, the acting member 40 is arranged on the rotating seat 24, and the rotating seat 24 is further provided with an opening 241, and the opening 241 is away from the connecting end 25 relative to the acting member 40, during the switching from the second state to the first state, the first free end 32 is connected with the second free end 42 after passing through the opening 241, and during the switching from the first state to the second state, the first free end 32 passes out of the opening 241 after being separated from the second free end 42. Of course, in other examples, the opening 241 and the acting member 40 can also be arranged on the roller 10, which will not be described here.

[0083] And / or, referring to Figure 8As shown, the support end 12 of the rotating seat 24 or the drum 10 provided with the acting member 40 is further provided with a reinforcing rib 242, which is connected with the acting member 40 and the inner wall of the support end 12 of the rotating seat 24 or the drum 10 provided with the acting member 40. The reinforcing rib 242 can increase the connection stability between the acting member 40 and the rotating seat 24 or the support end 12, so that the acting member 40 is not easily damaged in the process of cooperating with the clamping member 30; meanwhile, the reinforcing rib 242 can greatly improve the structural strength at the acting member 40.

[0084] In some specific examples, as shown in FIG. 2, the acting member 40 is arranged on the rotating seat 24, and the rotating seat 24 is further provided with a reinforcing rib 242, which is arranged on the side of the acting member 40 away from the connecting end 25 and connected with the acting member 40 and the inner wall of the rotating seat 24 respectively. Figure 8 As shown, the acting member 40 is arranged on the rotating seat 24, and the rotating seat 24 is further provided with a reinforcing rib 242, which is arranged on the side of the acting member 40 away from the connecting end 25 and connected with the acting member 40 and the inner wall of the rotating seat 24 respectively. Then, the reinforcing rib 242 here can increase the connection stability between the acting member 40 and the rotating seat 24, and also improve the structural strength of the acting member 40. Of course, in other examples, the reinforcing rib 242 can also be arranged on the support end 12 of the drum 10, which will not be described here.

[0085] The structure of the reinforcing rib 242 will be further described below by taking the example that the acting member 40 is arranged on the rotating seat 24 and the reinforcing rib 242 is connected between the acting member 40 and the inner wall of the rotating seat 24. Those skilled in the art should understand that the following structural features of the reinforcing rib 242 should also be applicable to the case that the reinforcing rib 242 and the acting member 40 are arranged on the support end 12 of the drum 10.

[0086] As shown in FIG. 2, the reinforcing rib 242 is arranged on the side of the acting member 40 away from the connecting end 25, and the reinforcing rib 242 is connected with the acting member 40 and the inner wall of the rotating seat 24 respectively. Figure 8As shown, the reinforcing rib 242 comprises a first guide surface 2421, which forms an acute angle with the central axis of the roller 10 in the direction extending towards the inner wall of the rotating seat 24. The first guide surface 2421 can provide a predetermined positioning guide when the acting member 40 and the clamping member 30 are clamped, so that the clamping member 30 can slide along the first guide surface 2421 after contacting the first guide surface 2421 and be further guided to the acting member 40. For example, in the examples, the angle of the acute angle ranges from 10 degrees to 80 degrees, for example, can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, etc. When the acute angle is selected to be a small angle, the first guide surface 2421 is closer to the inner wall of the rotating seat 24 as a whole, and the displacement rate of the clamping member 30 along the axial direction of the roller changes more greatly when the clamping member 30 slides along the first guide surface 2421 per unit time, so that the clamping member 30 can be guided to the acting member 40 more quickly; when the acute angle is selected to be a larger angle, the first guide surface 2421 is relatively flat as a whole, which is convenient for demolding. In the present disclosure, the structure of the reinforcing rib 242 can be adjusted according to actual needs.

[0087] and / or, as shown in Figure 8 The number of reinforcing ribs 242 is at least two, and the at least two reinforcing ribs 242 are arranged circumferentially along the inner wall of the rotating seat 24. The plurality of reinforcing ribs 242 can further enhance the connection strength between the acting member 40 and the rotating seat 24, and the first guide surface 2421 of the plurality of reinforcing ribs 242 can form a larger area of the guide area, so that the rotating seat 24 with the acting member 40 is more easily guided to a predetermined position during the abutting process with the roller 10 with the clamping member 30, and the clamping member 30 is conveniently guided to the acting member 40 along the first guide surface 2421 to form clamping.

[0088] and / or, in some examples, the number of clamping members 30 and the number of acting members 40 are the same or different. That is, the number of clamping members 30 and the number of acting members 40 can be the same, each clamping member 30 and the corresponding acting member 40 correspondingly clamped, that is, the clamping member 30 and the acting member 40 one-to-one correspondingly clamped; or a plurality of clamping members 30 correspond to one acting member 40 respectively, or a plurality of acting members 40 correspond to one clamping member 30 respectively.

[0089] and / or, in combination with Figure 6 and Figure 7As shown, the number of the engaging members 30 and the number of the acting members 40 are both at least two, and the at least two engaging members 30 and the at least two acting members 40 are arranged one by one. Then, by arranging the plurality of engaging members 30 and the plurality of acting members 40 one by one, after the corresponding connection of each engaging member 30 and each acting member 40, the support end 12 of the roller 10 can be stably connected with the rotating seat 24 through the entire matching surface. In the working process of the roller brush assembly 100 in the first state, the engaging members 30 and the acting members 40 are always connected and are not easy to be loosened.

[0090] Alternatively, the number of the engaging members 30 is at least two, and the number of the acting members 40 is one. When the engaging members 30 are connected with the acting members 40, the at least two engaging members 30 are connected with the one acting member 40. In these examples, the plurality of engaging members 30 can be connected with the one acting member 40 at the same time, which increases the clamping effect of the one acting member 40 and forms a reliable connection between the plurality of engaging members 30 and the one acting member 40. For example, the one acting member 40 can be a circular ring, and the outer ring thereof is connected to the inner wall of the rotating seat 24, and the plurality of engaging members 30 can be connected to the inner ring thereof.

[0091] And / or, the number of the engaging members 30 and the number of the acting members 40 are both at least two. The at least two acting members 40 are uniformly arranged on the inner wall of the rotating seat 24 in the circumferential direction, and the at least two engaging members 30 are uniformly arranged on the inner wall of the support end 12 of the roller 10 in the circumferential direction. Then, in these examples, the engaging members 30 and the acting members 40 can be reliably connected at multiple places on the matching surface in the circumferential direction, and the connection force on the entire matching surface is relatively uniform.

[0092] It can be understood that the above-mentioned arrangement of the engaging members 30 and the acting members 40 is also applicable to the case that the engaging members 30 are arranged on the rotating seat 24 and the acting members 40 are arranged on the support end 12 of the roller 10. That is, the number of the engaging members 30 and the number of the acting members 40 are both at least two. The at least two engaging members 30 are uniformly arranged on the inner wall of the rotating seat 24 in the circumferential direction, and the at least two acting members 40 are uniformly arranged on the inner wall of the support end 12 of the roller 10 in the circumferential direction.

[0093] In some examples, as shown in FIG. 1, the number of the engaging members 30 is one, and the number of the acting members 40 is at least two. The one engaging member 30 is connected with the at least two acting members 40. Figure 6 and Figure 7As shown, the supporting end 12 of the roller 10 is further provided with a mounting surface 122 arranged along the radial direction of the roller 10, the mounting surface 122 being the bottom surface of the mounting cavity 121; the first end of the clamping piece 30 is a first fixed end 31 connected to the mounting surface 122, and the second end of the clamping piece 30 is a first free end 32 away from the mounting surface 122 relative to the first fixed end 31; the first end of the acting piece 40 is a second fixed end 41 connected to the inner wall of the rotating seat 24, and the second end of the acting piece 40 is a second free end 42 arranged in a direction away from the inner wall of the rotating seat 24. At this time, the clamping piece 30 can move relative to the acting piece 40 and has a first position and a second position, that is, the roller brush assembly 100 is in the first state, the clamping piece 30 is in the first position, the clamping piece 30 is connected with the acting piece 40, and the roller brush assembly 100 is in the second state, the clamping piece 30 is in the second position, and the clamping piece 30 is disconnected with the acting piece 40. In these examples, the mounting surface 122 is arranged at the supporting end 12 of the roller 10, so that the arrangement position of the clamping piece 30 is more flexible, the clamping piece 30 can be directly arranged on the mounting surface 122, the clamping piece 30 does not need to extend out of the inner wall of the roller 10 at the supporting end 12 in the radial direction and then extend in the axial direction of the roller 10, but directly extends in the axial direction of the roller 10 with the mounting surface 122 as the base point and corresponds to the acting piece 40, so that the shape of the clamping piece 30 is simplified and the injection molding demolding is more convenient. Of course, in other examples, the mounting surface 122 can be omitted, and only part of the inner wall of the roller 10 is arranged to protrude in the radial direction as the arrangement position of the clamping piece 30.

[0094] Figure 4 Figure 5 Figure 20 Figure 21 As shown in

[0095] In some embodiments, as shown in Figure 8 The supporting rib 243 can further reinforce the strength of the side of the rotating seat 24 facing the supporting end 12, and can also limit the movement of the rotating seat 24 along the axial direction of the roller 10 during assembly, such as limiting the position of the clamping piece 30 arranged on the roller 10.

[0096] ​​​​And / or, the side of the rotating seat 24 away from the connecting end 25 is provided with a supporting rib 243, in the first state, the supporting rib 243 abuts against the mounting surface 122, then the supporting rib 243 in these examples can also make the rotating seat 24 and the mounting surface 122 form contact and limiting in the axial direction, so as to limit the maximum distance that the rotating seat 24 can be inserted along the axial direction of the roller 10, and in the first state, the rotating seat 24 and the mounting surface 122 can also be kept in stable contact.

[0097] And / or, as shown in Figure 6 and Figure 7 , the side of the connecting part between the first fixed end 31 and the mounting surface 122 is provided with a notch 1221, which facilitates the injection molding of the clamping piece 30, effectively prevents deformation during injection molding, and also makes the clamping piece 30 after molding have a larger elastic deformation allowance.

[0098] In some examples of the present disclosure, as shown in Figure 11 , Figure 12 , Figure 15 and Figure 16 , the rotating seat 24 or the supporting end 12 of the roller 10 provided with the acting piece 40 is also provided with a reset piece 60, the reset piece 60 is connected with the acting piece 40 and is used to provide the acting piece 40 with an acting force moving towards the clamping piece 30. The acting piece 40 moves away from the clamping piece 30 under the action of the second external force to disengage from the clamping piece 30, and the acting piece 40 moves towards the clamping piece 30 under the action of the reset piece 60 to connect the clamping piece 30. Then in these examples, the reset piece 60 can make the acting piece 40 have a tendency to remain in the clamping piece 30, so that the acting piece 40 can be in a constant connected state with the clamping piece 30 when the roller brush assembly 100 is in the first state, ensuring the stable connection of the rotating seat 24 or the roller 10 and not easy to disengage.

[0099] Optionally, as shown in Figure 12 and Figure 16 , the rotating seat 24 or the supporting end 12 of the roller 10 provided with the acting piece 40 is also provided with a through hole 244, the position of the through hole 244 corresponds to the position of the clamping piece 30, and at least part of the acting piece 40 passes through the through hole 244. The acting piece 40 passing through the through hole 244 can further form a connection with the clamping piece 30, the through hole 244 can also effectively prevent the acting piece 40 from being ejected from the rotating seat 24 or the roller 10 under the action of the reset piece 60; the through hole 244 can also align the acting piece 40 and the clamping piece 30, facilitating the connection between the acting piece 40 and the clamping piece 30.

[0100] Optionally, as shown in Figure 17As shown, the acting member 40 is provided with a rotating shaft 44, which is rotatably connected to the rotating seat 24 or the supporting end 12 of the roller 10 provided with the acting member 40. The acting member 40 rotates around the rotating shaft 44 under the action of the second external force, so as to move away from the clamping member 30. In these examples, the acting member 40 rotates around the rotating shaft 44 as the center line of rotation by applying the second external force, so as to move relative to the clamping member 30 and separate from the clamping member 30. The rotating shaft 44 herein can be a separate rotating shaft penetrating the acting member 40 and connected to the acting member 40, or can be an integrated rotating shaft 44 of the acting member 40.

[0101] In some specific examples, as shown in Figure 17 The rotating shaft 44 includes coaxially arranged first rotating shaft 441 and second rotating shaft (not shown), and the acting member 40 includes opposite first side and second side. The first rotating shaft 441 is connected to the first side of the acting member 40, and the second rotating shaft is connected to the second side of the acting member 40. By protruding the first rotating shaft 441 and the second rotating shaft on the opposite sides of the acting member 40, the acting member 40 itself can be part of the rotating shaft 44, without the need to additionally manufacture a separate whole rotating shaft, without the need to consider the space reserved for connecting the rotating shaft 44 in the acting member 40, and without the need to consider how to connect the separate rotating shaft 44 to the acting member 40. It is only necessary to make the first rotating shaft 441 located on the first side and the second rotating shaft located on the second side coaxial, which simplifies the structure and processing technology.

[0102] In some examples of the present disclosure, as shown in Figure 10 , Figure 12 , Figure 16 and Figure 17 The rotating seat 24 provided with the acting member 40 or the supporting end 12 of the roller 10 is further provided with a reset member 60 and an unlocking member 50. The reset member 60 is connected to the acting member 40 and is used to provide the acting member 40 with an action force moving towards the clamping member 30. The unlocking member 50 is connected to the acting member 40. The unlocking member 50 moves under the action of the second external force to drive the acting member 40 to move away from the clamping member 30 to disengage from the clamping member 30. The acting member 40 moves towards the clamping member 30 under the action of the reset member 60 to connect the clamping member 30. In these examples, by providing the reset member 60 and the unlocking member 50, the unlocking member 50 facilitates the application of the second external force to make the acting member 40 overcome the action force of the reset member 60 and move away from the clamping member 30, so as to be unlocked. The reset member 60 can reset the acting member 40 after the second external force disappears and move towards the clamping member 30, so as to make the acting member 40 and the clamping member 30 reconnect, which is convenient to operate. For example, the second external force has a component perpendicular to the unlocking member 50, that is, the unlocking member 50 is pressed vertically downward to drive the acting member 40 to move in the horizontal direction and compress the reset member 60 to disengage from the clamping member 30.

[0103] Optionally, as shown in Figure 11 and Figure 12 The unlocking member 50 is separate from the acting member 40 and is in sliding connection with the acting member 40. The unlocking member 50 is moved under the action of the second external force to drive the acting member 40 to move away from the clamping member 30. That is, the external force applied to the unlocking member 50 can be transmitted to the acting member 40. The second external force can form a component force in the disassembly direction on the sliding surface of the unlocking member 50 and the acting member 40. The component force overcomes the force of the restoring member 60 on the acting member 40, and the resultant force makes the acting member 40 move in the direction of separating from the clamping member 30. The separate structure of the unlocking member 50 and the acting member 40 can be more flexible. The structures of the two can be designed according to their movement paths, and only the contact between the two on the sliding surface needs to be maintained.

[0104] Further, as shown in Figure 12 The acting member 40 includes a third surface 47, and the unlocking member 50 includes a fourth surface 51. The third surface 47 and the fourth surface 51 are correspondingly arranged and extend away from the central axis of the roller 10 in a direction that forms an acute angle with the direction of the central axis of the roller 10 from the support end 12 to the driving end 11. The third surface 47 and the fourth surface 51 are in sliding cooperation during the switching between the first state and the second state. In the examples, the acute angle ranges from 20 degrees to 70 degrees, for example, 20 degrees, 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, etc. When the acute angle is within the above range, the component force of the applied second external force can drive the unlocking member 50 and the acting member 40 to move, and the displacement of the movement can be controlled within a reasonable range. By applying the second external force to the unlocking member 50, the component force of the second external force can overcome the friction force of the contact surface between the third surface 47 and the fourth surface 51 to move the unlocking member 50. The component force on the contact surface can further overcome the force of the restoring member 60 and the friction force at the bottom of the acting member 40, so that the unlocking member 50 and the acting member 40 move together away from the clamping member 30. When resetting, after the second external force on the unlocking member 50 is removed, because there is a certain friction force on the contact surface between the unlocking member 50 and the acting member 40, the restoring member 60 is relatively gentle when resetting the acting member 40, and it is not easy to generate a large impact force on the clamping member 30 by the acting member 40.

[0105] In some specific examples, as shown in Figure 11 , Figure 15As shown, the engaging member 30 is arranged on the support end 12 of the roller 10, and the acting member 40 is arranged on the rotating seat 24, at this time, the acting member 40 is movable relative to the engaging member 30, and has a first position and a second position, that is, in the first state of the roller brush assembly 100, the acting member 40 is in the first position, the engaging member 30 is connected with the acting member 40, and in the second state of the roller brush assembly 100, the acting member 40 is in the second position, the engaging member 30 is disconnected with the acting member 40.

[0106] It should be noted that the first position and the second position described herein do not correspond to unique positions respectively, but can be a range of positions. For example, when the engaging member 30 is in the first position and connected with the acting member 40, the first position can be the position when the engaging member 30 is just connected with the acting member 40, or can be the position when the engaging member 30 is fully abutted with the acting member 40. When the engaging member 30 is in the second position and disconnected with the acting member 40, the second position can be the position when the engaging member 30 is just disconnected with the acting member 40, or can be the position when the engaging member 30 is already disconnected with the acting member 40 and the distance between the engaging member 30 and the acting member 40 is less than the first distance, or can be the position when the engaging member 30 is already disconnected with the acting member 40 and the distance between the engaging member 30 and the acting member 40 is greater than the second distance.

[0107] In some specific examples, as shown in Figure 12 As shown, the rotating seat 24 is provided with the unlocking member 50 and the acting member 40, the unlocking member 50 and the acting member 40 are arranged separately and are connected in sliding mode, the acting member 40 comprises a third surface 47, the unlocking member 50 comprises a fourth surface 51, the third surface 47 and the fourth surface 51 are arranged correspondingly, and the angle between the direction in which the third surface 47 and the fourth surface 51 extend away from the central axis of the roller 10 and the direction in which the central axis of the roller 10 points from the support end 12 to the driving end 11 is an acute angle; in the process of switching between the first state and the second state, the third surface 47 and the fourth surface 51 are in sliding cooperation.

[0108] Optionally, as shown in Figure 15 and Figure 16As shown, the unlocking member 50 is integrally arranged with the acting member 40, and the unlocking member 50 is provided with a rotating shaft 44 rotatably connected to the rotating seat 24 or the support end 12 of the roller 10. The unlocking member 50 rotates around the rotating shaft 44 under the action of a second external force (for example, an action force vertically pressing the unlocking member 50 downward), to drive the acting member 40 to rotate around the rotating shaft 44, so that the acting member 40 moves away from the clamping member 30. The second external force arranged on the unlocking member 50 drives the unlocking member 50 to rotate along the rotating shaft 44, and in turn drives the acting member 40 to rotate along the rotating shaft 44, so that the acting member 40 rotates relative to the clamping member 30 and separates. After the second external force is removed, the restoring member 60 further acts on the acting member 40, so that the acting member 40 reverses along the rotating shaft 44 and moves to the position clamped with the clamping member 30. By reasonably setting the force arm of the rotating shaft 44 from the top end of the unlocking member 50 and the force arm of the rotating shaft 44 from the bottom end of the acting member 40, the acting member 40 can move a larger distance while the unlocking member 50 swings a smaller distance, so that the unlocking member 50 needs a smaller space to move, and the acting member 40 on the other side of the rotating shaft 44 moves a larger distance and separates from the clamping member 30 faster when the unlocking member 50 swings a smaller distance, thereby saving the setting space of the unlocking member 50 and improving the unlocking efficiency of the unlocking member 50 on the acting member 40.

[0109] Further, as shown in Figure 17 The unlocking member 50 is integrally arranged with the acting member 40, and the unlocking member 50 is provided with a rotating shaft 44 rotatably connected to the rotating seat 24 or the support end 12 of the roller 10. The rotating shaft 44 includes coaxially arranged first rotating shaft 441 and second rotating shaft (not shown in the figure), and the unlocking member 50 includes opposite first side and second side, the first rotating shaft 441 is connected with the first side of the unlocking member 50, and the second rotating shaft is connected with the second side of the unlocking member 50. That is, the rotating shaft 44 arranged on the unlocking member 50 can be two coaxially arranged first rotating shaft 441 and second rotating shaft protruding from the surface of the unlocking member 50, without being arranged as a whole rotating shaft, and the part of the unlocking member 50 coaxially arranged with the first rotating shaft 441 and the second rotating shaft can be part of the rotating shaft 44, so that the connection mode of the separately arranged rotating shaft 44 and the unlocking member 50 is not considered, the processing convenience is improved, and the structure is simplified. The coaxially arranged first rotating shaft 441 and second rotating shaft can make the unlocking member 50 rotate stably and the rotating track controllable.

[0110] In some specific examples, as shown in Figure 15 and Figure 16As shown, the rotating seat 24 is provided with an unlocking member 50 and an acting member 40, the unlocking member 50 is integrally arranged with the acting member 40, the unlocking member 50 is provided with a rotating shaft 44, the rotating shaft 44 is rotatably connected to the rotating seat 24, the rotating shaft 44 comprises coaxially arranged first rotating shaft 441 and second rotating shaft, the unlocking member 50 comprises opposite first side and second side, the first rotating shaft 441 is connected to the first side of the unlocking member 50 and the rotating seat 24 respectively, the second rotating shaft is connected to the second side of the unlocking member 50 and the rotating seat 24 respectively.

[0111] Of course, in other embodiments, the above-mentioned unlocking member 50 can not be provided, but the end of the acting member 30 is directly extended to the end of the support arm 20, and the second external force can be applied to the end by hand.

[0112] In addition, in other examples, the above-mentioned reset member 60 can not be provided, but two clamps, i.e. first clamp and second clamp, are arranged on the first support part 21 (such as the rotating seat 24), when one end of the acting member 40 moves to the position where the clamping member 30 is disengaged, the other end of the acting member 40 is limited in the first clamp; when one end of the acting member 40 moves to the position where the clamping member 30 is clamped, the other end of the acting member 40 is limited in the second clamp. In the example without the reset member 60, the external force needs to be applied to move the acting member 40 towards the clamping member 30 and make them clamped.

[0113] In some examples, as shown in Figure 12 and Figure 16 The clamping member 30 is arranged on the inner wall of the support end 12 of the roller 10, and the clamping member 30 has a matching port 123 for the acting member 40 to enter and exit, for example, the matching port 123 is a groove on the inner wall of the support end 12; the rotating seat 24 is provided with the acting member 40, and the acting member 40 comprises a clamping hook 48, in the first state, the clamping hook 48 is inserted into the matching port 123, in the second state, the clamping hook 48 is disengaged from the matching port 123. Then, in these examples, the acting member 40 and the clamping member 30 can form a stable connection through the insertion of the clamping hook 48 and the matching port 123; and the acting member 40 and the clamping member 30 can be disassembled through the disengagement of the clamping hook 48 from the matching port 123. The structure is simple and convenient to disassemble.

[0114] Further, as shown in Figure 12 and Figure 16As shown, the outer wall of the rotating base 24 is provided with a through-hole 244, the position of which corresponds to the position of the mating port 123. The hook 48 can pass through the through-hole 244 and be inserted into the mating port 123. The through-hole 244 allows the end of the actuating member 40 to protrude from the rotating base 24 and connect with the engaging member 30. After the through-hole 244 and the mating port 123 are aligned, pre-alignment between the actuating member 40 and the engaging member 30 can be achieved, facilitating connection between them. The through-hole 244 also effectively prevents the actuating member 40 from being ejected from the rotating base 24 or the roller 10 under the action of the reset member 60.

[0115] Furthermore, the rotating base 24 is provided with a reset member 60, which is connected to the actuating member 40 and provides a force to the actuating member 40 to move toward the engaging member 30. Under the action of a second external force, the actuating member 40 moves away from the engaging member 30 to disengage the hook 48 from the mating port 123. Under the force of the reset member 60, the actuating member 40 moves toward the engaging member 30 to insert the hook 48 into the mating port 123. In some other examples, the support end 12 of the roller 10 is provided with a reset member 60 and an actuating member 40; while the rotating base 24 is provided with an engaging member 30 and a mating port 123. No specific limitation is made here.

[0116] In some specific examples, the rotating base 24 is provided with an unlocking member 50. One end of the unlocking member 50 is connected to the actuating member 40, and the other end of the unlocking member 50 extends to the end face of the rotating base 24 or the end face of the support end 12 of the roller 10. That is to say, the degree of protrusion of the other end of the unlocking member 50 can be designed according to actual needs. For example, it can be set to be parallel to the end face of the rotating base 24, or protrude from the end face of the rotating base 24, or be recessed in the end face of the rotating base 24, or be parallel to the end face of the support end 12, as long as it is convenient for manual force application.

[0117] And / or, such as Figure 7 As shown, the inner wall of the support end 12 of the roller 10 is provided with abutment ribs 124. The abutment ribs 124 are arranged circumferentially on the inner wall of the support end 12 of the roller 10 and extend axially along the roller 10. The abutment ribs 124 can make the roller 10 and the rotating seat 24 tightly abut against each other in the radial direction of the roller 10, preventing the rotating seat 24 from wobbling in the roller 10. In some specific examples, the abutment ribs 124 include multiple abutment ribs evenly spaced along the inner wall of the support end 12, so that the abutment force of the abutment ribs 124 against the rotating seat 24 is sufficiently uniform, and the outer peripheral surface of the rotating seat 24 can achieve stable abutment with the abutment ribs 124 at multiple points.

[0118] In some examples, such as Figure 7 , Figure 8 , Figure 13 , Figure 14 , Figure 18 andFigure 19 As shown in the first and second states, the inner wall of the support end 12 of the roller 10 is provided with a first guide part 125, and the outer wall of the rotating seat 24 is provided with a second guide part 245. During the switching between the first state and the second state, the first guide part 125 and the second guide part 245 are in sliding cooperation. Through the sliding cooperation of the first guide part 125 and the second guide part 245, the rotating seat 24 and the roller 10 can be stably moved and are not easy to shake during assembly, and can be quickly assembled in place.

[0119] Optionally, one of the first guide part 125 and the second guide part 245 is a guide column, and the other is a guide groove. The guide column can be inserted into the guide groove. During the assembly of the rotating seat 24 and the roller 10, the guide column can be aligned with the guide groove to realize insertion. The interaction of the guide column and the guide groove not only can guide, but also can increase the connection stability of the rotating seat 24 and the roller 10 after cooperation.

[0120] And / or, as shown in Figure 4 , Figure 7 and Figure 21 , one of the first guide part 125 and the second guide part 245 is a guide column, and the other is a guide groove. The guide column can be inserted into the guide groove, and the end of the guide column inserted into the guide groove is provided with a second guide surface 126. The direction in which the second guide surface 126 extends towards the center axis of the roller 10 forms an acute angle with the direction in which the center axis of the roller 10 points from the support end 12 to the driving end 11 of the roller 10. By providing the second guide surface 126, the guide groove can slide along the second guide surface 126 before the guide groove is not aligned with the guide column during the introduction of the guide column into the guide groove, so that the guide column and the guide groove can be quickly and accurately aligned. The acute angle in these examples can be any angle in the range of 30 degrees to 70 degrees, which is not limited here.

[0121] And / or, as shown in Figure 4 , Figure 7 and Figure 21 , one of the first guide part 125 and the second guide part 245 is a guide column, and the other is a guide groove. The guide column can be inserted into the guide groove, and the guide column is hollow. The hollow design can effectively prevent deformation during injection molding and can also save materials.

[0122] And / or, the first guide part 125 and the second guide part 245 are both arranged along the axial direction of the roller 10, parallel to the direction of assembly of the rotating seat 24 and the roller 10, so as to facilitate the quick assembly of the rotating seat 24 and the roller 10.

[0123] And / or, the number of the first guide part 125 and the second guide part 245 is the same, that is, each first guide part 125 corresponds to a second guide part 245, and each first guide part 125 forms a guide cooperation with another second guide part 245 during assembly.

[0124] And / or, the number of the first guide part 125 and the second guide part 245 is at least two, and at least two first guide parts 125 and at least two second guide parts 245 are arranged one by one. Thus, the rotating seat 24 and the roller 10 can be pre-positioned and guided at least two positions during assembly, which improves the stability during assembly and effectively reduces the swing phenomenon of the rotating seat 24 and the roller 10 during assembly of the first guide part 125 and the second guide part 245.

[0125] And / or, as shown in Figure 10 、 Figure 13 、 Figure 14 、 Figure 19 The number of the first guide part 125 and the second guide part 245 is at least two, at least two first guide parts 125 are uniformly arranged on the inner wall of the support end 12 of the roller 10 in the circumferential direction, and at least two second guide parts 245 are uniformly arranged on the outer wall of the rotating seat 24 in the circumferential direction. Thus, the circumferential surface of the rotating seat 24 and the roller 10 can be stably assembled.

[0126] In some specific examples, the first guide part 125 is a guide groove recessed on the support end 12, and the second guide part 245 is a guide rib protruding on the outer wall of the rotating seat 24, and the guide rib cooperates with the guide groove to realize the guide.

[0127] The present disclosure provides a roller brush assembly 100 applied to a cleaning device 1000, and the cleaning device 1000 includes a body 200. Referring back to Figure 1 and Figure 2The rolling brush assembly 100 is detachably mounted to the machine body 200 and includes a mounted state and a detached state, the mounted state being a state in which the rolling brush assembly 100 is mounted to the machine body 200, and the detached state being a state in which the rolling brush assembly 100 is detached from the machine body 200; wherein the direction in which the rolling brush assembly 100 is mounted to the machine body 200 is a mounting direction, and the direction in which the rolling brush assembly 100 is detached from the machine body 200 is a detachment direction, the mounting direction being opposite to the detachment direction. The rolling brush assembly 100 includes a rolling cylinder 10 and a support arm 20; along the axial direction of the rolling cylinder 10, the rolling cylinder 10 includes a driving end 11 and a supporting end 12, and the driving end 11 of the rolling cylinder 10 is detachably connected to the machine body 200; the support arm 20 extends along the radial direction of the rolling cylinder 10, and the support arm 20 includes a first supporting part 21 and a second supporting part 22, in the extension direction of the support arm 20, the first supporting part 21 is closer to the rolling cylinder 10 than the second supporting part 22, the first supporting part 21 is detachably connected to the supporting end 12 of the rolling cylinder 10, and the second supporting part 22 is detachably connected to the machine body 200; when the rolling brush assembly 100 is in the mounted state and a third external force acts on different positions of the support arm 20, the frictional force between the first supporting part 21 and the supporting end 12 of the rolling cylinder 10 is different, so that under the action of the third external force, the rolling brush assembly 100 as a whole can be detached from the machine body 200 or the support arm 20 can be detached from the rolling cylinder 10, wherein the third external force has a component force in the detachment direction.

[0128] The rolling brush assembly 100 provided by the present disclosure can be used in the cleaning device 1000. The driving end 11 of the rolling brush assembly 100 is detachably connected to the machine body 200, the supporting end 12 of the rolling brush assembly 100 is detachably connected to the machine body through the second supporting part 22, and by applying a third external force to different positions of the support arm 20, the rolling brush assembly 100 can have different frictional forces between the first supporting part 21 and the supporting end 12 of the rolling cylinder 10 when the component force of the third external force in the detachment direction is different. When the frictional force between the two is less than the component force of the third external force in the detachment direction, the first supporting part 21 is detached relative to the rolling cylinder 10, so that the support arm 20 and the rolling cylinder 10 are detached; when the frictional force between the two is greater than the component force of the third external force in the detachment direction, the first supporting part 21 remains connected to the rolling cylinder 10, and at this time, if the component force of the third external force in the detachment direction is greater than the frictional force between the driving end 11 of the rolling cylinder 10 and the machine body 200, the rolling brush assembly 100 as a whole can be detached from the machine body 200, which is convenient to operate.

[0129] The technical solutions of the rolling cylinder 10 and the support arm 20 in the foregoing various embodiments of the present disclosure are also applicable to the embodiments of the rolling brush assembly 100 to which the third external force is applied to the support arm 20, which will not be described herein.

[0131] The cleaning device 1000 provided by the present disclosure, when the rolling brush assembly 100 is arranged on the cleaning device 1000, the rotation of the roller 10 relative to the machine body 200 realizes the cleaning of the surface to be cleaned. When the rolling brush assembly 100 needs to be replaced, the rolling brush assembly 100 can be quickly separated from the machine body 200 by applying the first external force or the third external force, so as to make the rolling brush assembly 100 separate from the machine body 200, at this time, the entire rolling brush assembly 100 can be selected to be replaced; or, by applying the second external force, the roller 10 and the support arm 20 are separated, which facilitates the replacement of the roller 10 to restore the cleaning power of the rolling brush assembly 100, without the need to replace the support arm 20, thereby saving the cost, and the disassembly and assembly are convenient and the user experience is high.
