Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, and more particularly, to a rolling brush device, a cleaning equipment and a cleaning system. BACKGROUND

[0002] With the development of technology, more and more occasions begin to use cleaning equipment. For example, cleaning equipment (e.g., a robot vacuum cleaner or a robot mop) is used in household indoor, large-scale places and other occasions to clean a to-be-cleaned surface. Taking the robot vacuum cleaner as an example, the robot vacuum cleaner rolls up the garbage on the to-be-cleaned surface by using a rolling brush, sucks the garbage into a containing cavity of the rolling brush device by using a fan, and collects the garbage in a dust box. However, in the case that the current robot vacuum cleaner cleans a to-be-cleaned surface with a large garbage adsorption force or a soft to-be-cleaned surface (e.g., a carpet), a better vacuum degree cannot be formed between the rolling brush device of the robot vacuum cleaner and the to-be-cleaned surface, resulting in a poor cleaning effect of the robot vacuum cleaner on the to-be-cleaned surface with a large garbage adsorption force or the soft to-be-cleaned surface.

DETAILED DESCRIPTION

[0050] Embodiments of the present disclosure will be further described below with reference to the drawings. The same or similar reference numerals are used throughout the drawings and their functions are the same or similar. In addition, the embodiments of the present disclosure described below with reference to the drawings are exemplary and are only used to explain the embodiments of the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0051] With the development of technology, more and more occasions begin to use cleaning devices. For example, cleaning devices (such as a sweeping robot or a mopping robot) are used in occasions such as a home indoor environment and a large place to clean a to-be-cleaned surface. Taking the sweeping robot as an example, the sweeping robot rolls up the garbage on the to-be-cleaned surface by using a rolling brush, sucks the garbage into an accommodating cavity of the rolling brush device by using a fan, and collects the garbage in a dust box through a suction inlet. However, in the case that the current sweeping robot cleans a to-be-cleaned surface with a large garbage adsorption force or a soft to-be-cleaned surface (for example, a carpet), a good vacuum degree cannot be formed between the rolling brush device of the sweeping robot and the to-be-cleaned surface, which leads to a poor cleaning effect of the sweeping robot on the to-be-cleaned surface with a large garbage adsorption force or the soft to-be-cleaned surface. To solve this problem, the present disclosure provides a rolling brush device 100 Figures 1 to 10 , a cleaning device 1000 Figure 11 , a cleaning system 10000 Figure 12 , a control method of a rolling brush device Figures 13 to 20 , and a control device 500Figure 21 (as shown), and computer-readable storage media.

[0052] Please see Figure 1 and Figure 2 This disclosure provides a roller brush device 100, applied to a cleaning equipment 1000. Figure 11 As shown, during the cleaning process, the cleaning device 1000 uses a roller brush device 100 to clean debris from the surface to be cleaned. The roller brush device 100 includes a roller brush housing 10, a roller brush 30, and a cover 50. The roller brush housing 10 is disposed within the body 300 of the cleaning device 1000 and has a communicating receiving cavity 11 and a suction port 13. The suction port 13 allows debris from the surface to be cleaned to enter the receiving cavity 11. The roller brush 30 is disposed within the receiving cavity 11 and can rotate relative to the roller brush housing 10. The cover 50 is disposed outside the roller brush housing 10 and can move relative to the roller brush housing 10 to change the opening size of the suction port 13.

[0053] Please combine Figure 11 Specifically, this disclosure also provides a cleaning device 1000, which is a device for cleaning surfaces to be cleaned. The surfaces to be cleaned may include, but are not limited to, floors, carpets, marble surfaces, or glass surfaces. The cleaning device 1000 may be a floor scrubber, a vacuum cleaner, a robotic vacuum cleaner, a robotic mop, or a robotic vacuum and mop combo. A floor scrubber can be used to wipe and clean surfaces to be cleaned; a robotic vacuum cleaner can be used to clean surfaces to be cleaned; a robotic mop can be used to wipe and clean surfaces to be cleaned; and a robotic vacuum and mop combo can integrate the functions of both types of robots, meaning it can be used to both clean and wipe surfaces to be cleaned. The cleaning device 1000 of this disclosure is illustrated using a robotic vacuum and mop combo as an example.

[0054] In some embodiments, the cleaning device 1000 includes a roller brush device 100 and a body 300, with the roller brush device 100 disposed on the body 300 (e.g., mounted on the bottom of the body 300). When the cleaning device 1000 cleans a surface to be cleaned, at least a portion of the roller brush device 100 is in direct contact with the surface, and the roller brush device 100 is used to roll up debris (e.g., dust and other dirt) on the surface and transport it toward the receiving cavity 11. The body 300 is also provided with a negative pressure device (e.g., a fan), which is used to draw debris through the suction port 13 into the dust box of the body 300, where the dust box collects debris from the surface to be cleaned. The cooperation between the roller brush device 100 and the body 300 effectively cleans debris from the surface, freeing up the user's hands to a certain extent and providing a better user experience.

[0055] The machine body 300 and the roller brush housing 10 can be an integral structure or a split structure. In the case of a split structure, the machine body 300 and the roller brush housing 10 can be processed separately and then connected together by welding, fastener connection, etc. In the case of an integral structure, the machine body 300 and the roller brush housing 10 can also be processed by integral molding process such as injection molding.

[0056] Please refer to Figure 1 , Figure 3 and Figure 4 , the roller brush housing 10 is a structure for mounting the roller brush 30, and the roller brush housing 10 also serves to temporarily store garbage, that is, during the process of the roller brush 30 sweeping up the garbage on the surface to be cleaned and the garbage being sucked into the dust box by the fan, the roller brush housing 10 can prevent the garbage swept up by the roller brush 30 from being blown out. The accommodation cavity 11 is a structure for mounting the roller brush 30 therein, and the suction inlet 13 is located at one side of the accommodation cavity 11 close to the surface to be cleaned (for example, below Figure 2 ), and the suction inlet 13 is used for the garbage on the surface to be cleaned to enter the accommodation cavity 11 through the suction inlet 13.

[0057] Please refer to Figure 2 , Figure 4 and Figure 5 , the roller brush 30 is used to rotate relative to the roller brush housing 10 to roll up the garbage on the surface to be cleaned and transport the garbage towards the accommodation cavity 11, and the garbage passes through the suction inlet 13 and the accommodation cavity 11 and finally enters the dust box of the machine body 300. For example, the roller brush 30 can include a roller body and a brush body, the roller body of the present disclosure is a cylindrical structure, and the brush body is a spiral structure extending along the axial direction of the roller body. The brush body can be a rubber strip, a hair strip, or a combination of a rubber strip and a hair strip. The number of brush bodies can be, but is not limited to, one, two, three, four or more. In the case of multiple brush bodies, the multiple brush bodies are distributed at intervals on the roller body. In the case of a spiral structure of the brush body of the roller brush 30, the roller brush 30 can more effectively gather and capture garbage, and the cleaning efficiency of the roller brush 30 is higher. Moreover, the spiral brush body has a larger contact area with the surface to be cleaned per unit time, thereby improving the coverage area during cleaning and the cleaning effect on the surface to be cleaned.

[0058] Please refer to Figures 1 to 4In some embodiments, the cover 50 is disposed outside the roller brush housing 10, and the cover 50 is movably connected with the roller brush housing 10. In one example, the cover 50 is directly movably connected with the roller brush housing 10. In another example, the cover 50 is indirectly movably connected with the roller brush housing 10, for example, the cover 50 is indirectly movably connected with the roller brush housing 10 through a third element or a third assembly (for example, the driving assembly 70 and the transmission assembly 90 described below). At least a portion of the cover 50 covers the roller brush housing 10, and the cover 50 is rotatable relative to the roller brush housing 10. When the cover 50 rotates relative to the roller brush housing 10, the cover 50 can change the opening size of the suction port 13, for example, block or open the suction port 13. In other embodiments, at least a portion of the cover 50 covers the front of the roller brush housing 10, and the cover 50 is movable relative to the roller brush housing 10. When the cover 50 moves relative to the roller brush housing 10, the cover 50 can also change the opening size of the suction port 13, for example, block or open the suction port 13.

[0059] In this document, the cover 50 blocks or opens the suction port 13, including: the cover 50 blocks the suction port 13 to the maximum, the cover 50 opens the suction port 13 to the maximum, and the cover 50 is in an intermediate state between blocking the suction port 13 to the maximum and opening the suction port 13 to the maximum.

[0060] When the cover 50 opens the suction port 13 to the maximum, the maximum gap exists between the free end 53 of the cover 50 and the surface to be cleaned, and the garbage on the surface to be cleaned can enter the accommodation cavity 11 through the gap between the free end 53 of the cover 50 and the surface to be cleaned, that is, the garbage on the surface to be cleaned can enter the accommodation cavity 11 through the suction port 13 and be sucked into the dust box by the fan. At this time, the roller brush device 100 can clean the garbage with a larger volume on the surface to be cleaned, and the volume of the garbage here can be measured by the height of the garbage in the height direction of the roller brush device 100. When the gap between the free end 53 of the cover 50 and the surface to be cleaned is greater than or equal to the height of the garbage on the surface to be cleaned, the garbage on the surface to be cleaned can enter the accommodation cavity 11 through the suction port 13, and the cleaning effect of the roller brush device 100 on the surface to be cleaned is better.

[0061] In the case that the cover 50 covers the suction port 13 to the maximum extent, there is almost no gap (or a minimum gap) between the free end 53 of the cover 50 and the surface to be cleaned. At this time, the sealing performance in the accommodation cavity 11 is good, that is, a good vacuum degree is formed between the roller brush device 100 and the surface to be cleaned, and the fan can concentrate the suction force to suck the garbage on the surface to be cleaned corresponding to the suction port 13, that is, the garbage on the part of the surface to be cleaned covered by the roller brush device 100 can be effectively sucked into the dust box, and the cleaning effect of the roller brush device 100 on the surface to be cleaned is good. For example, in the case that the surface to be cleaned is a carpet, the suction force of the carpet on the garbage (such as dust, hair and debris, etc.) is relatively large due to the relatively soft material of the carpet, and the carpet is difficult to be effectively cleaned. In the case that the cover 50 covers the suction port 13 to the maximum extent, the roller brush 30 rolls up the garbage on the carpet, and the fan can concentrate the suction force to effectively suck the garbage into the dust box, and the cleaning effect of the roller brush device 100 on the carpet is good.

[0062] In the case that the cover 50 is in an intermediate state between covering the suction port 13 to the maximum extent and opening the suction port 13 to the maximum extent, there is a gap between the free end 53 of the cover 50 and the surface to be cleaned, and the size of the gap is between the maximum gap and the minimum gap, and the garbage on the surface to be cleaned can also enter the accommodation cavity 11 through the gap between the free end 53 of the cover 50 and the surface to be cleaned.

[0063] In the roller brush device 100 of the embodiment of the present disclosure, the cover 50 is arranged outside the roller brush housing 10, and the cover 50 can move relative to the roller brush housing 10 to change the opening size of the suction port 13. In the case that the garbage to be cleaned has a large volume, the cover 50 can move relative to the roller brush housing 10 to increase the opening size of the suction port, so that the garbage with a large volume can enter the accommodation cavity 11 through the suction port 13. In the case that the surface to be cleaned has a large suction force on the garbage, the cover 50 can move relative to the roller brush housing 10 to reduce the opening size of the suction port 13, so that the sealing performance between the surface to be cleaned and the accommodation cavity 11 is good, and the roller brush device 100 can concentrate the suction force to suck the garbage on the surface to be cleaned, and the cleaning effect of the roller brush device 100 on the surface to be cleaned is good.

[0064] The roller brush device 100 will be further described below in combination with the drawings.

[0065] Please refer to Figure 1 and Figure 2The first limiting part 15 and the second limiting part 17 are spaced apart along the movement direction of the cover body 50, and the cover body 50 is freely movable between the first limiting part 15 and the second limiting part 17. The movement direction includes a first direction X and a second direction Y opposite to each other. When the cover body 50 moves relative to the roller brush housing 10 along the first direction X, the cover body 50 abuts against the first limiting part 15 to reach a first position (as shown in Figure 8 When the cover body 50 moves relative to the roller brush housing 10 along the second direction Y, the cover body 50 abuts against the second limiting part 17 to reach a second position (as shown in Figure 6 The opening size of the suction inlet 13 in the first position is greater than the opening size of the suction inlet 13 in the second position.

[0066] It should be noted that the movement of the cover body 50 relative to the roller brush housing 10 includes rotation and movement. In an embodiment, the cover body 50 rotates relative to the roller brush housing 10 along the first direction X, and the cover body 50 rotates towards the direction away from the surface to be cleaned to increase the opening size of the suction inlet 13. The cover body 50 rotates relative to the roller brush housing 10 along the second direction Y, and the cover body 50 rotates towards the direction close to the surface to be cleaned to decrease the opening size of the suction inlet 13. At this time, the first direction X is the clockwise direction and the second direction Y is the counterclockwise direction from the perspective shown in Figure 2 Alternatively, the first direction X is the counterclockwise direction and the second direction Y is the clockwise direction from the opposite perspective shown in Figure 2 In another embodiment, the cover body 50 moves relative to the roller brush housing 10 along the first direction X, and the cover body 50 moves towards the direction away from the surface to be cleaned to increase the opening size of the suction inlet 13. The cover body 50 moves relative to the roller brush housing 10 along the second direction Y, and the cover body 50 rotates towards the direction close to the surface to be cleaned to decrease the opening size of the suction inlet 13. At this time, the first direction X is the upward direction away from the surface to be cleaned, and the second direction Y is the downward direction close to the surface to be cleaned. Only the rotation of the cover body 50 relative to the roller brush housing 10 is described herein.

[0067] Please refer to Figures 6 to 8In some embodiments, as the waste enters the dust box through the suction inlet 13, a negative pressure is created at the suction inlet 13 during the suction process, allowing the airflow at the suction inlet 13 to carry the waste into the dust box along with it. When the opening size of the suction inlet 13 is large, i.e., the interception area of ​​the inlet airflow at the suction inlet 13 is large, the roller brush device 100 can clean larger pieces of waste on the surface to be cleaned. When the opening size of the suction inlet 13 is small, i.e., the interception area of ​​the inlet airflow at the suction inlet 13 is small, the sealing of the accommodating cavity 11 is better, and the waste on the part of the surface to be cleaned covered by the roller brush device 100 can be effectively sucked into the dust box, resulting in a better cleaning effect from the roller brush device 100.

[0068] The cover 50 can rotate relative to the roller brush housing 10 to change the opening size of the suction port 13. For example, the opening size of the suction port 13 can be the height of the free end 53 of the cover 50 relative to the surface to be cleaned in a direction perpendicular to the surface. That is, the greater the height of the free end 53 of the cover 50 from the surface to be cleaned in the direction perpendicular to the surface, the larger the opening size of the corresponding suction port 13. The opening size may include the minimum opening degree (…). Figure 6 As shown, this corresponds to the minimum height and maximum opening of the free end 53. Figure 8 As shown, this corresponds to the maximum height of the free end 53) and multiple intermediate openings between the minimum and maximum openings. Figure 7 (As shown). When the opening size of the inlet 13 is at its minimum, the cover 50 covers the inlet 13 to the maximum extent. At this time, the airflow interception area S1 at the inlet 13 is almost zero, the sealing of the accommodating cavity 11 is good, and the cleaning effect of the roller brush device 100 on the surface to be cleaned is good. When the opening size of the inlet 13 is at its maximum, the cover 50 opens the inlet 13 to the maximum extent. At this time, the cover 50 can rotate relative to the roller brush housing 10 to the maximum angle it can rotate, the airflow interception area S at the inlet 13 reaches its maximum, and the roller brush device 100 can effectively clean larger debris on the surface to be cleaned. When the opening size of the inlet 13 is at multiple intermediate openings between the minimum and maximum openings, the cover 50 opens the inlet 13. The airflow interception areas at the multiple intermediate openings of the inlet 13 can be S2, S3, S4, S5, S6, S7, and Sn, respectively. Among them, S1 <S2<S3<S4<S5<S6<S7<Sn<S。

[0069] Please see Figures 3 to 5 Furthermore, in some embodiments, the roller brush device 100 further includes a drive assembly 70. The drive assembly 70 is disposed on the roller brush housing 10 or the body 300. Figure 11The driving assembly 70 is connected with the rolling brush 30 and the cover 50, and is configured to drive the rolling brush 30 to rotate relative to the rolling brush housing 10, and drive the cover 50 to move relative to the rolling brush housing 10 to change the opening size of the suction port 13. Specifically, the driving assembly 70 includes a driving member 71, and the driving assembly 70 drives the cover 50 to move to increase or decrease the opening size of the suction port 13 and drives the rolling brush 30 to rotate to clean the surface to be cleaned by the same driving member 71. The same driving member 71 can be one driving member or two or more driving members. For example, the driving assembly 70 includes one driving member 71, that is, one driving member 71 drives the cover 50 to move to increase or decrease the opening size of the suction port 13 and drives the rolling brush 30 to rotate to clean the surface to be cleaned. For another example, the driving assembly 70 includes two driving members 71, that is, one of the driving members 71 drives the cover 50 to move to increase or decrease the opening size of the suction port 13, and the other driving member 71 drives the rolling brush 30 to rotate to clean the surface to be cleaned.

[0070] The surface to be cleaned includes a target area and a non-target area. For example, the target area can be a carpet area, a floor mat area, a foot mat area, a yoga mat area, a rubber mat area, a straw or bamboo mat area, a recognized relatively dirty area, a user-defined area that needs to be cleaned deeply, etc., and the non-target area can be other cleaning areas such as an open ground.

[0071] In some embodiments, during at least part of the time period when the cleaning device 1000 cleans the non-target area, the driving assembly 70 drives the rolling brush 30 to rotate and / or the wiping member 61 of the cleaning device 1000 to move to clean the non-carpet area, and / or the cover 50 to move to increase the opening size of the suction port 13. When the cleaning device 1000 cleans the non-target area, the rolling brush 30 and / or the wiping member 61 and / or the side brush 60 are controlled to move according to different cleaning modes; if the opening size of the suction port 13 is decreased before entering the non-target area (for example, the opening size of the suction port 13 is decreased when cleaning the target area, and then the non-target area is entered for cleaning), the cover 50 is driven to move to increase the opening size of the suction port 13; if the opening size of the suction port 13 is not decreased before entering the non-target area (for example, the opening size of the suction port 13 is not adjusted when cleaning other non-target areas or when the cleaning device 1000 is taken out of the base station 3000), the cover 50 does not need to be driven to move, that is, the opening size of the suction port 13 does not need to be adjusted.

[0072] In some embodiments, the cover 50 is driven to move to reduce the opening size of the suction port 13 by gravity and / or the restoring force of the elastic member during at least part of the time period when the cleaning device 1000 cleans the target area, and the driving assembly 70 drives the roller brush 30 to rotate to clean the target area; wherein the elastic member is arranged between the cover 50 and the roller brush housing 10 and is configured to provide the cover 50 with a restoring force for moving towards the second direction Y. For example, the cleaning device 1000 controls the movement of the roller brush 30 and / or the wiping member 61 and / or the side brush 60 according to different cleaning modes when cleaning the target area; if the opening size of the suction port 13 is not reduced before entering the target area (for example, the opening size of the suction port 13 is not adjusted when cleaning a non-target area, and the target area is entered again for cleaning), the cover 50 is driven to move to reduce the opening size of the suction port 13; if the opening size of the suction port 13 has been reduced before entering the target area (for example, the opening size of the suction port 13 has been reduced when cleaning other target areas), the cover 50 does not need to be driven to move, that is, the opening size of the suction port 13 does not need to be adjusted. In the above embodiment, the cover 50 is driven to move to increase the opening size of the suction port 13 by using the driving force of the driving assembly 70, and the cover 50 is driven to move to reduce the opening size of the suction port 13 by using the gravity of the cover 50 and / or the restoring force of the elastic member, thereby saving part of the driving force and reducing energy consumption.

[0073] Referring to Figure 11 The roller brush housing 10 comprises a roller brush cover 20, the roller brush cover 20 covers the suction port 13, the roller brush cover 20 comprises a first side 21 and a second side 22, and the first side 21 is located in front of the second side 22 in the direction of travel of the cleaning device 1000; when the cleaning device 1000 is placed on a flat surface to be cleaned, the first side 21 is not in contact with the surface to be cleaned, the second side 22 is in contact with the surface to be cleaned, and the roller brush 30 is in contact with the surface to be cleaned through the suction port 13. When the cleaning device 1000 cleans the surface to be cleaned, the first side 21 of the roller brush cover 20 is not in contact with the surface to be cleaned, which facilitates large garbage to enter the accommodation cavity 11 through the gap between the surface to be cleaned and the accommodation cavity 11, but also causes the vacuum degree between the surface to be cleaned and the accommodation cavity 11 to be low, and the fan needs a larger suction force to achieve the cleaning effect, especially for the surface to be cleaned which needs to be cleaned deeply, the energy consumption is larger.

[0074] The roller brush device 100 further comprises a transmission assembly 90, the transmission assembly 90 is connected with the driving assembly 70 and the cover 50, and the transmission assembly 90 is configured to transmit the driving force of the driving assembly 70 to the cover 50 and the roller brush 30, so as to enable the cover 50 to move relative to the roller brush housing 10 and enable the roller brush 30 to rotate relative to the roller brush housing 10.

[0075] In the case that the cover 50 needs to rotate relative to the brush housing 10 along the first direction X, the driving assembly 70 drives the transmission assembly 90 to move, so that the transmission assembly 90 drives the cover 50 to rotate along the first direction X. In the case that the cover 50 needs to rotate relative to the brush housing 10 along the second direction Y, the driving assembly 70 drives the transmission assembly 90 to move, so that the transmission assembly 90 drives the cover 50 to rotate along the second direction Y; or, the cover 50 rotates along the second direction Y due to the effect of gravity and / or the restoring force of the elastic member.

[0076] Referring to Figure 4 and Figure 5 In some embodiments, the driving assembly 70 is also connected with the brush 30 and is further used to drive the brush 30 to rotate relative to the brush housing 10.

[0077] In the case that the brush device 100 needs to clean the surface to be cleaned, the driving assembly 70 first drives the cover 50 to rotate relative to the brush housing 10 along the first direction X or the second direction Y to a predetermined position through the transmission assembly 90, and then the driving assembly 70 drives the brush 30 to rotate, so that the brush 30 can roll up the garbage on the surface to be cleaned, and the garbage enters the dust box through the suction port 13.

[0078] Referring to Figure 3 and Figure 4 Specifically, in some embodiments, the driving assembly 70 includes a driving member 71 and at least one driving tooth 73, the driving member 71 is arranged on the brush housing 10 or the machine body 300 Figure 11 , the driving tooth 73 is connected with the driving member 71 and the transmission assembly 90, the driving member 71 is used to drive the driving tooth 73 to rotate, and the driving tooth 73 is used to transmit the driving force of the driving member 71 to the transmission assembly 90.

[0079] Please refer to Figures 6 to 10The driving member 71 can include a motor. When the roller brush device 100 is started, the motor is powered on, the driving tooth 73 is connected with the output shaft of the motor, and thus the motor can drive the driving tooth 73 to rotate. The driving tooth 73 of the present disclosure is a gear, and at least part of the transmission assembly 90 can rotate coaxially with the driving tooth 73. When the driving tooth 73 rotates, the driving tooth 73 can drive the transmission assembly 90 to rotate. In the process of rotating, the transmission assembly 90 can drive the cover body 50 to rotate in the first direction X or the second direction Y, so that the cover body 50 can change the opening size of the suction inlet 13. The number of the driving tooth 73 can be one, two, three, four or more, but is not limited to. When the cover body 50 rotates relative to the roller brush shell 10 to a predetermined position, the driving tooth 73 rotates to drive the roller brush 30 to rotate, so that the roller brush 30 can clean the surface to be cleaned. Preferably, the roller brush device 100 further comprises a connecting member 40 for connecting the driving tooth 73 and the roller brush 30. When the driving tooth 73 rotates, the driving tooth 73 can drive the roller brush 30 to rotate through the connecting member 40.

[0080] Please refer to Figure 3 and Figure 4 In some embodiments, at least one driving tooth 73 includes a front-end driving tooth 731, which is directly connected with the driving member 71 and the transmission assembly 90. The driving member 71 is used to drive the front-end driving tooth 731 to rotate, and the front-end driving tooth 731 is used to transmit the driving force of the driving member 71 to the transmission assembly 90. When the driving tooth 73 includes the front-end driving tooth 731, the transmission efficiency of the driving tooth 73 is higher, the structure of the driving assembly 70 is simpler, and the overall weight of the roller brush device 100 is lighter, so as to reduce the weight of the cleaning equipment and facilitate the user to carry and place.

[0081] The number of the front-end driving tooth 731 can be one. One front-end driving tooth 731 is connected with the output shaft of the driving member 71 and coaxially connected with at least part of the transmission assembly 90. When the driving member 71 drives the front-end driving tooth 731 to rotate, the front-end driving tooth 731 can drive the transmission assembly 90 to rotate together, so that the transmission assembly 90 can drive the cover body 50 to rotate. The roller brush 30 is connected with the front-end driving tooth 731 through the connecting member 40. In the process of rotating, the front-end driving tooth 731 can drive the roller brush 30 to rotate, so that the roller brush 30 can clean the surface to be cleaned. Please refer to Figures 5 to 8 For example, when the front-end driving tooth 731 rotates in the first direction X, the front-end driving tooth 731 can drive the transmission assembly 90 to rotate, so that the transmission assembly 90 can drive the cover body 50 to rotate to a predetermined position. When the front-end driving tooth 731 rotates in the second direction Y, the front-end driving tooth 731 can drive the roller brush 30 to rotate in the first direction X, so that the roller brush 30 can rotate to clean the surface to be cleaned.

[0082] Please refer to​Figure 3 and Figure 4 In other embodiments, at least one drive tooth 73 includes a front drive tooth 731 and a rear drive tooth 733. The front drive tooth 731 is directly connected to the drive member 71, and the rear drive tooth 733 is directly connected to both the front drive tooth 731 and the transmission assembly 90. The drive member 71 drives the front drive tooth 731 to rotate, and the driving force of the drive member 71 is transmitted to the transmission assembly 90 through the front drive tooth 731 and the rear drive tooth 733. When the drive tooth 73 includes a front drive tooth 731 and a rear drive tooth 733, the transmission accuracy of the drive tooth 73 is high, and the overall stability of the drive assembly 70 is good.

[0083] The number of front drive teeth 731 and rear drive teeth 733 can both be one. The front drive tooth 731 is connected to the output shaft of the drive member 71. The rear drive tooth 733 meshes with the front drive tooth 731 and is coaxially connected to at least a portion of the transmission assembly 90. When the drive member 71 drives the front drive tooth 731 to rotate, the front drive tooth 731 can drive the rear drive tooth 733 to rotate, thereby the rear drive tooth 95 can drive the transmission assembly 90 to rotate together. The roller brush 30 is connected to the rear drive tooth 733 via a connector 40. During rotation, the rear drive tooth 733 can drive the roller brush 30 to rotate, thus enabling the roller brush 30 to clean the surface to be cleaned. Please refer to... Figures 5 to 8 For example, when the driving member 71 drives the front driving tooth 731 to rotate along the second direction Y, the rear driving tooth 733 rotates along the first direction X. The rear driving tooth 733 can drive the transmission assembly 90 to rotate, so that the transmission assembly 90 can drive the cover 50 to rotate to a predetermined position. When the front driving tooth 731 rotates along the first direction X, the rear driving tooth 733 rotates along the second direction Y. The rear driving tooth 733 can drive the roller brush 30 to rotate along the first direction X, so that the roller brush 30 can rotate to clean the surface to be cleaned.

When the drive tooth 73 includes a front drive tooth 731, a rear drive tooth 733, and at least one intermediate drive tooth 735, the transmission accuracy of the drive tooth 73 is higher, and the overall stability of the drive assembly 70 is better.

[0085] The number of the intermediate driving teeth 735 includes, but is not limited to, one, two, three, four or more. The number of the intermediate driving teeth 735 in the present disclosure is two. The two intermediate driving teeth 735 are engaged with each other. The first intermediate driving tooth 735 close to the front driving tooth 731 is also engaged with the front transmission tooth 93. The second intermediate driving tooth 735 close to the rear driving tooth 733 is also engaged with the rear transmission tooth 95.

[0086] The front driving tooth 731 is connected with the output shaft of the driving member 71. The rear driving tooth 733 is coaxially connected with at least part of the transmission assembly 90 through the two intermediate driving teeth 735. When the driving member 71 drives the front driving tooth 731 to rotate, the front driving tooth 731 drives the first intermediate driving tooth 735 to rotate, the first intermediate driving tooth 735 drives the second intermediate driving tooth 735 to rotate, and the second intermediate driving tooth 735 can drive the rear driving tooth 733 to rotate, so that the transmission assembly 90 can rotate together with the rear transmission tooth 95.

The first driving tooth 7311, the second driving tooth 7351, the third driving tooth 7353 and the fourth driving tooth 7331 are engaged in sequence. The fourth driving tooth 7331 is connected with the transmission assembly 90. The driving force of the driving member 71 is transmitted to the transmission assembly 90 through the first driving tooth 7311, the second driving tooth 7351, the third driving tooth 7353 and the fourth driving tooth 7331.

[0089] The first driving tooth 7311 can be equivalent to the front-end driving tooth 731, the second driving tooth 7351 and the third driving tooth 7353 can be equivalent to the middle driving tooth 735, and the fourth driving tooth 7331 can be equivalent to the rear-end driving tooth 733.

In the case that the first driving tooth 7311, the second driving tooth 7351, the third driving tooth 7353 and the fourth driving tooth 7331 need to be maintained and replaced, the second sub-portion 753 can be detached from the first sub-portion 751, and then the first driving tooth 7311, the second driving tooth 7351, the third driving tooth 7353 and the fourth driving tooth 7331 can be disassembled or maintained.

[0094] The driving member 71 can be located inside the mounting box 75, or can be located outside the mounting box 75. In the case that the driving member 71 is located inside the mounting box 75, the mounting box 75 can also protect the driving member 71. In the case that the driving member 71 is located outside the mounting box 75, the overall volume of the mounting box 75 is smaller, and the material cost can be saved. At this time, at least a part of the driving member 71 (for example, the output shaft of the driving member 71) penetrates through the side wall of the mounting box 75 to enter the inside of the mounting box 75 and is connected with the first driving tooth 7311.

The transmission tooth is connected with the one-way transmission member 91 and the cover body 50, and the transmission tooth is used to transmit the driving force to the cover body 50.

[0096] The one-way transmission member 91 is rotatable in one direction and non-rotatable in another direction. In one example, the one-way transmission member 91 is rotatable in the first direction X and non-rotatable in the second direction Y. In another example, the one-way transmission member 91 is rotatable in the second direction Y and non-rotatable in the first direction X.

The one-way bearing is sleeved on at least part of the fourth driving tooth 7331, and the inner ring of the one-way bearing is fixedly connected with at least part of the fourth driving tooth 7331. When the fourth driving tooth 7331 rotates, the fourth driving tooth 7331 drives the inner ring of the one-way bearing to rotate together.

[0097] When the fourth driving tooth 7331 rotates in the first direction X, the inner ring of the one-way bearing also rotates in the first direction X, and the balls or rollers of the one-way bearing can smoothly roll in the rolling seats, thereby driving the outer ring of the one-way bearing to rotate in the first direction X. The outer ring of the one-way bearing is fixedly connected with at least part of the transmission tooth, and the outer ring of the one-way bearing can drive at least part of the transmission tooth to rotate in the first direction X, thereby driving the cover body 50 to rotate relative to the roller brush housing 10. When the fourth driving tooth 7331 rotates in the second direction Y, the inner ring of the one-way bearing also rotates in the second direction Y. At this time, the balls or rollers of the one-way bearing are limited by the shape of the rolling seat and cannot roll, thereby the inner ring of the one-way bearing cannot drive the outer ring of the one-way bearing to rotate, and the outer ring of the one-way bearing also cannot drive the transmission tooth to rotate, that is, when the fourth driving tooth 7331 rotates in the second direction Y, the cover body 50 will not rotate relative to the roller brush housing 10.

[0098] The transmission tooth of the present disclosure is a gear, and the number of transmission teeth includes, but is not limited to, one, two, three, four, or more. The transmission tooth is used to drive the cover body 50 to rotate relative to the roller brush housing 10. When the fourth driving tooth 7331 rotates in the first direction X, the fourth driving tooth 7331 can drive the transmission tooth to rotate through the one-way transmission member 91, thereby the transmission tooth can drive the cover body 50 to rotate to change the opening size of the suction port 13. When the transmission tooth drives the cover body 50 to rotate to a predetermined position, the fourth driving tooth 7331 is switched to rotate in the second direction Y. At this time, the transmission tooth does not rotate, thereby the cover body 50 also does not rotate relative to the roller brush housing 10, and the cover body 50 remains in the current position. When the fourth driving tooth 7331 rotates in the second direction Y, the fourth driving tooth 7331 drives the roller brush 30 to rotate through the connecting member 40, thereby the roller brush 30 can clean the surface to be cleaned.

[0099] Please see Figure 6 and Figure 7 In some embodiments, the transmission assembly 90 includes a front drive tooth 93, which is connected to a rear drive tooth 733 (fourth drive tooth 7331) via a one-way transmission member 91. The cover 50 is rotatably connected to the mounting box 75 and / or the roller brush housing 10. The rear drive tooth 733 drives the front drive tooth 93 to rotate, and the front drive tooth 93 drives the cover 50 to rotate relative to the roller brush housing 10. When the transmission tooth includes the front drive tooth 93, the transmission efficiency of the transmission tooth is higher, the structure of the transmission assembly 90 is simpler, and the overall weight of the roller brush device 100 is lighter, making it easier for users to handle and place.

[0100] Please combine Figure 7 In one example, at least a portion of the cover 50 engages with the front drive gear 93, meaning the cover 50 is drive-connected to the front drive gear 93. In this case, the one-way drive member 91 can be a structure that can rotate in the second direction Y but not in the first direction X. The opening size of the suction port 13 is the minimum opening ( Figure 8 (as shown) or intermediate opening ( Figure 6 In the case shown), when the fourth drive tooth 7331 rotates along the second direction Y, the outer ring of the one-way transmission member 91 drives the front transmission tooth 93 to rotate along the second direction Y. The front transmission tooth 93 meshes with at least part of the cover 50, so that the cover 50 can rotate along the first direction X to increase the opening size of the suction port 13. Figure 7 and Figure 7 (As shown). When the fourth drive tooth 7331 rotates along the first direction X, the outer ring of the one-way transmission member 91 does not rotate, so neither the front drive tooth 93 nor the cover 50 rotates, and the cover 50 remains in its current position. At this time, the fourth drive tooth 7331 drives the roller brush 30 to rotate along the first direction X through the connector 40, so that the roller brush 30 can clean the surface to be cleaned.

[0101] In another example, at least a portion of the cover 50 is fixedly connected to the front drive gear 93. In this case, the one-way drive member 91 can be a structure that can rotate in the first direction X but cannot rotate in the second direction Y. The opening size of the suction port 13 is the minimum opening ( Figure 8 (as shown) or intermediate opening ( Figure 3 In the case shown), when the fourth drive tooth 7331 rotates along the first direction X, the outer ring of the one-way transmission member 91 drives the front transmission tooth 93 to rotate along the first direction X. The front transmission tooth 93 is at least partially fixedly connected to the cover 50, so that the front transmission tooth 93 can drive the cover 50 to rotate along the first direction X, thereby increasing the opening size of the suction port 13. Figure 4 and Figures 5 to 8When the fourth driving tooth 7331 rotates in the second direction Y, the outer ring of the one-way transmission member 91 does not rotate, so that the front end transmission tooth 93 and the cover body 50 do not rotate, and the cover body 50 remains in the current position. At this time, the fourth driving tooth 7331 drives the roller brush 30 to rotate in the first direction X through the connecting member 40, so that the roller brush 30 can clean the surface to be cleaned.

[0102] Please refer to Figure 6 and Figure 7 In some other embodiments, the transmission assembly 90 comprises the front end transmission tooth 93 and the rear end transmission tooth 95, the front end transmission tooth 93 is connected with the rear end driving tooth 733 (the fourth driving tooth 7331) through the one-way transmission member 91, the cover body 50 is rotatably connected with the mounting box 75 and / or the roller brush housing 10, the rear end transmission tooth 95 is directly connected with the front end transmission tooth 93 and the cover body 50, the rear end driving tooth 733 is used to drive the front end transmission tooth 93 to rotate, the front end transmission tooth 93 is used to drive the rear end transmission tooth 95 to rotate, and the rear end transmission tooth 95 is used to drive the cover body 50 to rotate relative to the roller brush housing 10. In the case of the transmission teeth comprising the front end transmission tooth 93 and the rear end transmission tooth 95, the transmission precision of the transmission teeth is higher, and the overall stability of the transmission assembly 90 is better. When the fourth driving tooth 7331 rotates, the fourth driving tooth 7331 drives the front end transmission tooth 93 to rotate in the same direction (one-way) through the one-way transmission member 91. The front end transmission tooth 93 is engaged with the rear end transmission tooth 95, and in the case of the rotation of the front end transmission tooth 93, the rear end transmission tooth 95 rotates in the direction opposite to that of the front end transmission tooth 93.

[0103] Please refer to Figure 7 In one example, at least part of the cover body 50 is engaged with the rear end transmission tooth 95. At this time, the one-way transmission member 91 can be a structure that can rotate in the first direction X and cannot rotate in the second direction Y. In the case that the opening size of the suction port 13 is the minimum opening size (as shown in Figure 8 or the intermediate opening size (as shown in Figure 3 When the fourth driving tooth 7331 rotates in the first direction X, the outer ring of the one-way transmission member 91 drives the front end transmission tooth 93 to rotate in the first direction X, the front end transmission tooth 93 drives the rear end transmission tooth 95 to rotate in the second direction Y, and at least part of the cover body 50 is engaged with the rear end transmission tooth 95, so that the cover body 50 can rotate in the first direction X to increase the opening size of the suction port 13 (as shown in Figure 4 and Figures 5 to 8 When the fourth driving tooth 7331 rotates in the second direction Y, the outer ring of the one-way transmission member 91 does not rotate, so that the front end transmission tooth 93, the rear end transmission tooth 95 and the cover body 50 do not rotate, and the cover body 50 remains in the current position. At this time, the fourth driving tooth 7331 drives the roller brush 30 to rotate in the first direction X through the connecting member 40, so that the roller brush 30 can clean the surface to be cleaned.

[0104] In another example, at least a portion of the cover 50 is fixedly connected with the rear end transmission gear 95. In this case, the one-way transmission member 91 can be configured to be rotatable in the second direction Y and not rotatable in the first direction X. When the opening size of the suction port 13 is at the minimum opening size (shown in Figure 6 ), the intermediate opening size (shown in Figure 10 ), and the maximum opening size (shown in Figure 6 ), the outer ring of the one-way transmission member 91 drives the rear end transmission gear 95 to rotate in the second direction Y when the fourth drive gear 7331 rotates in the second direction Y, and the rear end transmission gear 95 drives the cover 50 to rotate in the first direction X when the fourth drive gear 7331 rotates in the first direction X. In this way, the cover 50 can be driven to rotate in the first direction X to increase the opening size of the suction port 13 (shown in Figure 7 ). When the fourth drive gear 7331 rotates in the first direction X, the outer ring of the one-way transmission member 91 does not rotate, and thus the front end transmission gear 93, the rear end transmission gear 95, and the cover 50 do not rotate, and the cover 50 remains at the current position. In this case, the fourth drive gear 7331 drives the roller brush 30 to rotate in the second direction Y through the connecting member 40, so that the roller brush 30 can clean the surface to be cleaned.

[0105] Please refer to Figure 8 and Figure 9 In some embodiments, the transmission assembly 90 includes the front end transmission gear 93, the rear end transmission gear 95, and at least one intermediate transmission gear. The front end transmission gear 93 is connected with the rear end drive gear 733 through the one-way transmission member 91. The cover 50 is rotatably connected with the mounting box 75 and / or the roller brush housing 10. The rear end transmission gear 95 is directly connected with the front end transmission gear 93 and the cover 50. The intermediate transmission gear is engaged with the front end transmission gear 93 and the rear end transmission gear 95. The rear end drive gear 733 is used to drive the front end transmission gear 93 to rotate. The driving force of the rear end drive gear 733 is transmitted to the cover 50 through the front end transmission gear 93, the intermediate transmission gear, and the rear end transmission gear 95.

[0106] Please refer to Figure 10 The number of intermediate transmission gears includes but is not limited to one, two, three, four, or more. For example, when the rear end transmission gear 95 is engaged with at least a portion of the cover 50, and the intermediate transmission gear includes two (a first intermediate transmission gear and a second intermediate transmission gear), the outer ring of the one-way transmission member 91 drives the rear end transmission gear 95 to rotate in the second direction Y when the fourth drive gear 7331 rotates in the second direction Y, and the rear end transmission gear 95 drives the cover 50 to rotate in the first direction X when the fourth drive gear 7331 rotates in the first direction X. In this way, the cover 50 can be driven to rotate in the first direction X to increase the opening size of the suction port 13 (shown in Figure 6 ). Figure 9When the fourth driving tooth 7331 rotates in the first direction X, the outer ring of the one-way transmission member 91 drives the front end transmission tooth 93 to rotate in the first direction X, the front end transmission tooth 93 drives the first intermediate transmission tooth to rotate in the second direction Y, the first intermediate transmission tooth drives the second intermediate transmission tooth to rotate in the first direction X, the second intermediate transmission tooth drives the rear end transmission tooth 95 to rotate in the second direction Y, and the rear end transmission tooth 95 is engaged with at least part of the cover body 50, so that the cover body 50 can rotate in the first direction X to increase the opening size of the suction inlet 13. Figure 10 and Figure 7 When the fourth driving tooth 7331 rotates in the second direction Y, the outer ring of the one-way transmission member 91 does not rotate, so that the front end transmission tooth 93, the intermediate driving tooth 735, the rear end transmission tooth 95 and the cover body 50 do not rotate, and the cover body 50 remains in the current position. At this time, the fourth driving tooth 7331 drives the roller brush 30 to rotate in the second direction Y through the connecting piece 40, so that the roller brush 30 can clean the surface to be cleaned.

[0107] Please refer to Figure 8 and Figure 8 In the embodiment of the present disclosure, the end of the cover body 50 connected with the transmission tooth is provided with a matching part 51; the at least one transmission tooth includes a front end transmission tooth 93 and a rear end transmission tooth 95, the front end transmission tooth 93 is sleeved on the one-way transmission member 91, the rear end transmission tooth 95 is installed on the mounting box 75 or the roller brush shell 10, and the rear end transmission tooth 95 includes a first engagement part 951 and a second engagement part 953 in the axial direction of the rear end transmission tooth 95, the first engagement part 951 is engaged with the front end transmission tooth 93, and the second engagement part 953 is engaged with the matching part 51.

[0108] Please refer to Figure 9 The end of the cover body 50 provided with the matching part 51 is connected with at least part of the structure of the mounting box 75, so that the cover body 50 can rotate relative to the mounting box 75. The matching part 51 is provided with a toothed area, and the toothed area of the matching part 51 is used to engage with the second engagement part 953. When the fourth driving tooth 7331 rotates in the first direction X, the outer ring of the one-way transmission member 91 drives the front end transmission tooth 93 to rotate in the first direction X, the front end transmission tooth 93 is engaged with the first engagement part 951, so that the front end transmission tooth 93 can drive the rear end transmission tooth 95 to rotate in the second direction Y, the toothed area of the matching part 51 is engaged with the second engagement part 953, so that the rear end transmission tooth 95 can drive the cover body 50 to rotate in the first direction X to increase the opening size of the suction inlet 13.

[0109] In other embodiments, the front transmission teeth 93 are gears, the rear transmission teeth 95 are a rack, the engaging portion 51 of the cover 50 engages with the rack, and the front transmission teeth 93 also engage with the rack. When the front transmission teeth 93 rotate in the first direction X, the front transmission teeth 93 engaging with the rear transmission teeth 95 can drive the rear transmission teeth 95 (the rack) to move downward, and the rear transmission teeth 95 engaging with the engaging portion 51 can drive the cover 50 to rotate in the first direction X to increase the opening size of the suction inlet 13.

[0110] Please refer to Figure 10 and Figure 10 In some embodiments, the front transmission teeth 93 include a toothed region 931 provided with teeth and a toothless region 933 not provided with teeth. When the front transmission teeth 93 rotate in the first direction X, the toothed region 931 of the front transmission teeth 93 engages with the rear transmission teeth 95, and the rear transmission teeth 95 rotate in the second direction Y, the rear transmission teeth 95 drive the cover 50 to rotate in the first direction X, and the opening size of the suction inlet 13 increases (as shown in Figure 4 、 Figure 3 and Figure 4 When the front transmission teeth 93 continue to rotate in the first direction X, the toothless region 933 of the front transmission teeth 93 corresponds to the rear transmission teeth 95, the front transmission teeth 93 are spaced apart from the rear transmission teeth 95, the cover 50 rotates in the second direction Y due to the action of gravity and / or the restoring force of the elastic member to reduce the opening size of the suction inlet. The elastic member is arranged between the cover 50 and the roller brush housing 10, and is used to provide the cover 50 with a restoring force moving toward the second direction Y (as shown in Figures 6 to 10 and Figure 6 ).

[0111] The toothed region 931 includes a first limit position 9311 and a second limit position 9313. When the second limit position 9313 of the toothed region 931 engages with the rear transmission teeth 95, the opening size of the suction inlet 13 is the minimum opening size. When the first limit position 9311 of the toothed region 931 engages with the rear transmission teeth 95, the opening size of the suction inlet 13 is the maximum opening size.

[0112] When the second limit position 9313 of the toothed region 931 engages with the rear transmission teeth 95 or the toothless region 933 engages with the rear transmission teeth 95 Figure 7 、 Figure 8 and Figure 9In the case that the opening size of the suction port 13 needs to be increased (for example, when a large volume of garbage needs to be cleaned), the front end transmission tooth 93 is rotated in the first direction X, and in the process of rotation, the toothed area 931 of the front end transmission tooth 93 is engaged with the first engagement part 951 of the rear end transmission tooth 95, so that the rear end transmission tooth 95 is rotated in the second direction Y, and the second engagement part 953 of the rear end transmission tooth 95 is engaged with the matching part 51 of the cover body 50, so that the cover body 50 can be rotated in the first direction X, and at this time, the opening size of the suction port 13 can be the intermediate opening degree (as shown in FIG. 9B). Figure 10 When the front end transmission tooth 93 continues to rotate in the first direction X so that the first limit position 9311 of the toothed area 931 is engaged with the rear end transmission tooth 95, the opening size of the suction port 13 can be the maximum opening degree (as shown in FIG. 9C). Figure 12 In the case that the cover body 50 opens the suction port 13, the roller brush device 100 can clean a large volume of garbage on the surface to be cleaned.

[0113] In the case that the roller brush device 100 needs to clean a surface to be cleaned (for example, a carpet) with strong garbage suction force, the front end transmission tooth 93 continues to rotate in the first direction X, and after the first limit position 9311 of the front end transmission tooth 93 is engaged with the rear end transmission tooth 95 (as shown in FIG. 9B), the toothless area 933 of the front end transmission tooth 93 starts to correspond to the rear end transmission tooth 95 (as shown in FIG. 9D). Figure 13 Figure 14 Figure 14 In the process of rotation of the front end transmission tooth 93, the cover body 50 will rotate in the second direction Y to cover the suction port 13 due to its own gravity and / or the restoring force of the elastic member, and the opening size of the suction port 13 again returns to the minimum opening degree (as shown in FIG. 9E). Figure 15 In the case that the opening size of the suction port 13 is the minimum opening degree, the rear end driving tooth 733 is rotated in the second direction Y, and the roller brush 30 can be rotated in the second direction Y by the rear end driving tooth 733 to clean the surface to be cleaned.

[0114] Please refer to Figure 16 In some embodiments, in the case that the transmission tooth includes the front end transmission tooth 93 and the rear end transmission tooth 95, the outer wall of the side of the mounting box 75 away from the roller brush housing 10 is provided with a first mounting part 755 and a second mounting part 757, at least part of the front end transmission tooth 93 extends into the first mounting part 755, one end of the cover body 50 provided with the matching part 51 is sleeved on the first mounting part 755, and the rear end transmission tooth 95 is sleeved on the second mounting part 757.

[0115] ​​The front end transmission tooth 93 and the rear end transmission tooth 95 are located outside the mounting box 75 and connected with at least part of the structure of the mounting box 75. The first mounting part 755 is a ring structure, the one-way transmission member 91 is located in the ring space of the first mounting part 755 and connected with at least part of the structure of the fourth driving tooth 7331, and at least part of the structure of the front end transmission tooth 93 also extends into the ring space of the first mounting part 755 and is located between the side wall of the first mounting part 755 and the outer ring of the one-way transmission member 91, so that the first mounting part 755 can support and position the one-way transmission member 91 and the front end transmission tooth 93. When the fourth driving tooth 7331 rotates, the driving force can be transmitted to the front end transmission tooth 93 through the one-way transmission member 91, so that the front end transmission tooth 93 can rotate. One end of the cover body 50 provided with the matching part 51 is sleeved on the outer peripheral wall of the first mounting part 755, on the one hand, the first mounting part 755 can support and position the cover body 50, on the other hand, the cover body 50 can also rotate relative to the first mounting part 755 along the first direction X and the second direction Y to change the opening size of the suction inlet 13. The second mounting part 757 is a cylindrical protruding structure, the rear end transmission tooth 95 is sleeved on the second mounting part 757, the second mounting part 757 can support and position the rear end transmission tooth 95, and the rear end transmission tooth 95 can also rotate relative to the second mounting part 757, so as to drive the cover body 50 to rotate.

[0116] It should be noted that the connection or transmission relationship between the various driving teeth, transmission teeth, roller brushes and cover bodies, and the control of their movement directions, etc. in this paper are only exemplary descriptions, which can be adjusted according to the actual situation, and the disclosure is not limited. For example, the number of driving teeth and transmission teeth can be appropriately increased or decreased, for example, the setting position of the driving tooth and the transmission tooth can be adjusted, for example, the movement direction of the driving tooth, the transmission tooth, the roller brush and the cover body can be changed.

[0117] Please refer to Figure 18 and Figure 17 , further, in some embodiments, the roller brush device 100 further comprises a position detection assembly 80, the position detection assembly 80 is arranged on at least one of the cover body 50, the roller brush shell 10, the driving assembly 70 and the transmission assembly 90, the position detection assembly 80 is used for detecting the real-time position of the cover body 50, the real-time position of the cover body 50 can be represented by the real-time angle of the cover body 50 relative to the roller brush shell 10. The driving assembly 70 is used for driving the cover body 50 to move relative to the roller brush shell 10 according to the real-time position and the type of the surface to be cleaned to adjust the opening size of the suction inlet 13. Specifically, in some embodiments, the position detection assembly 80 comprises a Hall sensor 81 and a magnetic member 83, one of the Hall sensor 81 and the magnetic member 83 is arranged on the cover body 50, the transmission assembly 90 or the driving assembly 70, and the other is arranged on the roller brush shell 10.

[0118] In one embodiment, the Hall sensor 81 is arranged on the cover 50, and the magnetic member 83 is arranged on the roller brush housing 10. In another embodiment, the Hall sensor 81 is arranged on the transmission assembly 90, and the magnetic member 83 is arranged on the roller brush housing 10. In this embodiment, the Hall sensor 81 can be arranged on the front end transmission tooth 93, or the Hall sensor 81 can be arranged on the rear end transmission tooth 95. In still another embodiment, the magnetic member 83 is arranged on the cover 50, and the Hall sensor 81 is arranged on the roller brush housing 10. In yet another embodiment, the magnetic member 83 is arranged on the transmission assembly 90, and the Hall sensor 81 is arranged on the roller brush housing 10. In this embodiment, the magnetic member 83 can be arranged on the front end transmission tooth 93, or the magnetic member 83 can be arranged on the rear end transmission tooth 95. Other arrangements of the Hall sensor 81 and the magnetic member 83 are not described in detail herein. According to actual needs, a plurality of sets of Hall sensors 81 and corresponding magnetic members 83 can be arranged, for example, one set of Hall sensor 81 and corresponding magnetic member 83 is arranged at a position corresponding to the maximum opening degree and the minimum opening degree, and the number of sets of Hall sensors 81 and corresponding magnetic members 83 can be increased according to the number of intermediate opening degrees.

[0119] The cover 50 can have a plurality of stop positions during rotation relative to the roller brush housing 10 along the first direction X, and the driving assembly 70 can control the rotation of the cover 50 relative to the roller brush housing 10 to stop at a target stop position according to the real-time position and the type of the surface to be cleaned. In the case where the driving assembly 70 drives the cover 50 to stop at the target stop position, the rear end driving member 71 moves along the second direction Y to drive the rotation of the roller brush 30. The type of the surface to be cleaned includes a non-target area (for example, a surface to be cleaned with relatively small adsorption of garbage) and a target area (for example, a surface to be cleaned with relatively large adsorption of garbage).

[0120] Please refer to Figure 19 The stop positions of the cover 50 can include L1, L2, L3, L4, L5, L6, and Ln. The real-time position (angle) of the cover 50 corresponding to the stop position of the cover 50 can be α1, α2, α3, α4, α5, α6, and αn. For example, if the initial position of the cover 50 is as shown in Figure 20 If the surface to be cleaned is a non-target area, and the cover 50 needs to stop at the stop position L1, as shown in Figure 21 When the Hall detector and the magnetic member 83 cooperate to detect that the real-time angle of the cover 50 relative to the roller brush housing 10 is α1, the driving assembly 70 stops driving the cover 50 to rotate. If the surface to be cleaned is a non-target area, and the cover 50 needs to stop at the stop position L2, as shown in ​As shown, when the real-time angle of the cover 50 rotating relative to the brush housing 10 is detected by the cooperation of the Hall detector and the magnetic piece 83 to be a2, the driving assembly 70 stops driving the cover 50 to rotate. At this time, if the cleaning equipment 1000 is on the target area for cleaning, and the cover 50 needs to be parked at the stop position L3, the cleaning efficiency can be further improved by further concentrating the suction force in the containing cavity 11, and the cover 50 can be parked at the stop position L4. ​ As shown, when the real-time angle of the cover 50 rotating relative to the brush housing 10 is detected by the cooperation of the Hall detector and the magnetic piece 83 to be a3, the driving assembly 70 stops driving the cover 50 to rotate. If it is desired to further improve the cleaning efficiency, the suction force in the containing cavity 11 can be further concentrated, and the cover 50 can be parked at the stop position L4. ​ As shown, when the real-time angle of the cover 50 rotating relative to the brush housing 10 is detected by the cooperation of the Hall detector and the magnetic piece 83 to be a4, the driving assembly 70 stops driving the cover 50 to rotate.

[0121] The different stop positions correspond to different opening sizes of the suction port 13. For example, when the stop position of the cover 50 can be L1, the cross-sectional area of the airflow at the suction port 13 is S1. When the stop position of the cover 50 can be L2, the cross-sectional area of the airflow at the suction port 13 is S2. When the stop position of the cover 50 can be L3, the cross-sectional area of the airflow at the suction port 13 is S3. When the stop position of the cover 50 can be L4, the cross-sectional area of the airflow at the suction port 13 is S4. When the stop position of the cover 50 can be Ln, the cross-sectional area of the airflow at the suction port 13 is Sn.

[0122] Please refer to ​ The cleaning system 10000 includes the cleaning equipment 1000 and the base station 3000. The base station 3000 has a parking position for the cleaning equipment 1000 to park and is used for maintaining the cleaning equipment 1000. When the cleaning equipment 1000 is maintained in the base station 3000, the types of maintenance include but are not limited to charging, dust collection, cleaning and washing of cleaning parts, replenishment of clean water, and sewage extraction. It can be understood that the cleaning equipment 1000 can complete at least one of the following in the base station 3000: 1. The base station 3000 charges the cleaning equipment 1000; 2. The base station 3000 recycles the garbage (for example, the garbage in the dust box or the sewage tank of the cleaning equipment) on the cleaning equipment 1000 into its dust collection container; 3. The base station 3000 washes the cleaning parts (for example, washes the mop, cleans the brush, and washes the roller) of the cleaning equipment 1000; 4. The base station 3000 replenishes clean water to the clean water box of the cleaning equipment 1000; 5. The base station 3000 recycles the dirt in the sewage tank of the cleaning equipment 1000 into its dirt container and discharges it to the outside. The above types of maintenance are only exemplary descriptions and are not limited by the disclosure.

[0123] In the cleaning system 10000 of the present disclosure, the cover 50 of the roller brush device 100 is arranged on the roller brush housing 10, and the cover 50 is movable relative to the roller brush housing 10 to change the opening size of the suction inlet 13. In the case of cleaning a larger volume of garbage, the cover 50 can be moved relative to the roller brush housing 10 to increase the opening size of the suction inlet, so that the larger volume of garbage can enter the accommodation cavity 11 through the suction inlet 13. In the case of cleaning a surface to be cleaned that has a larger adsorption force on garbage, the cover 50 can be moved relative to the roller brush housing 10 to reduce the opening size of the suction inlet 13, so that the accommodation cavity 11 has better sealing, and the roller brush device 100 can concentrate the adsorption force to adsorb the garbage on the surface to be cleaned, and the roller brush device 100 has better cleaning effect on the surface to be cleaned.

[0124] Please refer to ​ The present disclosure also provides a control method of a roller brush device. The control method is applied to the roller brush device 100 of any of the above embodiments, and the control method comprises the following steps.

[0125] 02: During at least part of the time period in which the cleaning device 1000 cleans the target area, the cover 50 is controlled to move to reduce the opening size of the suction inlet 13, and the driving assembly 70 is controlled to drive the roller brush 30 to rotate to clean the target area.

[0126] The surface to be cleaned includes a target area and a non-target area. The target area is taken as an example of a carpet. Since the carpet has a relatively soft material and a relatively large adsorption force on garbage (such as dust, hair, and debris), the carpet is difficult to be effectively cleaned, and therefore, under the same conditions, the adsorption force of the non-target area on garbage is smaller than that of the target area. When the cleaning device 1000 cleans the target area, considering that most of the garbage on the target area is difficult to be adsorbed and cleaned, and that the adsorption force needs to be concentrated to clean, the opening size of the suction inlet 13 is adjusted to a smaller opening degree, and then the roller brush 30 rolls up the garbage on the target area, so that the fan can effectively suck the garbage into the dust box to achieve a better cleaning effect.

[0127] The opening size of the suction inlet 13 can be set to be different when the cleaning device 1000 cleans the target area and the non-target area. For example, when the cleaning device 1000 moves from the non-target area to the target area, the opening size of the suction inlet 13 needs to be controlled to be reduced. For another example, when the cleaning device 1000 moves from the target area to the non-target area, the opening size of the suction inlet 13 needs to be controlled to be increased. In some embodiments, the opening size of the suction inlet 13 is reduced when the cleaning device 1000 cleans the target area, and the opening size of the suction inlet 13 is increased or restored (for example, the opening size of the suction inlet 13 is restored to the opening size before the target area is cleaned) after the target area is cleaned or the cleaning device 1000 leaves the target area.

[0128] In some embodiments, the timing of controlling the cover 50 to move to reduce the opening size of the suction port 13 can be when part of the cleaning device 1000 has reached the target area, for example, the edge brush 60 located in front of the traveling direction of the cleaning device 1000 can clean the target area, for another example, the roller brush 30 located in the middle of the traveling direction of the cleaning device 1000 can clean the target area, for another example, the sensor located at the left or right side of the traveling direction of the cleaning device 1000 can identify the target area; or can be when the entire cleaning device 1000 has reached the target area, for example, the mop 61 located at the rear of the traveling direction of the cleaning device 1000 can clean the target area, for another example, the sensor located at the tail of the traveling direction of the cleaning device 1000 can identify the target area.

[0129] The timing of controlling the driving assembly 70 to drive the roller brush 30 to rotate to clean the target area can be before, at the same time or after controlling the cover 50 to move to reduce the opening size of the suction port 13. For example, the cover 50 can be controlled to move to reduce the opening size of the suction port 13 first. After the opening size of the suction port 13 is reduced, the cover 50 is kept at the position, and then the driving assembly 70 drives the roller brush 30 to rotate to remove the garbage with large suction force.

[0130] In addition to the rotation of the roller brush 30, the edge brush 60 and the mop 61 can also operate according to the corresponding cleaning mode when the cleaning device 1000 cleans the target area. For example, when the cleaning mode is sweeping and mopping at the same time, the roller brush 30, the edge brush 60 and the mop 61 all operate.

[0131] Please refer to ​ In some embodiments, the step of controlling the cover 50 to move to reduce the opening size of the suction port 13 includes: controlling the cover 50 to move to make the cover 50 contact the target area.

[0132] In some embodiments, the cover 50 is controlled to move to reduce the opening size of the suction port 13 to make the cover 50 contact the target area, and for example, the opening size of the suction port 13 can be the minimum opening. In the case that the cover 50 contacts the target area, there is almost no gap (or the minimum gap) between the free end 53 of the cover 50 and the surface to be cleaned. At this time, the sealing performance in the accommodation cavity 11 is good, that is, a good vacuum degree is formed between the roller brush device 100 and the surface to be cleaned, and the fan can concentrate the suction force to suck the garbage at the position corresponding to the suction port 13 on the surface to be cleaned, that is, the garbage on the part of the surface to be cleaned covered by the roller brush device 100 can be effectively sucked into the dust box, and the cleaning effect of the roller brush device 100 on the surface to be cleaned is good.

[0133] and / or, please also refer to​ In some embodiments, the method of controlling the movement of the cover 50 to reduce the opening size of the suction port 13 comprises: 023. moving the cover 50 due to gravity and / or the restoring force of an elastic member, wherein the elastic member is arranged between the cover 50 and the roller brush housing 10 and is configured to provide a restoring force to the cover 50 to move in a direction close to the surface to be cleaned.

[0134] In some embodiments, the power for controlling the movement of the cover 50 to reduce the opening size of the suction port 13 is the movement of the cover 50 due to gravity and / or the restoring force of an elastic member, i.e. no power is output by the driving assembly 70, which saves power output. For example, the cover 50 directly moves to a position closest to the target area due to gravity, and at this time, the opening size of the suction port 13 can be the smallest.

[0135] and / or, please refer to ​ In some embodiments, the method of controlling further comprises: 03. controlling to increase the operating power of a fan of the cleaning device 1000, wherein the fan is in communication with the accommodation cavity 11, and during the operation of the fan, the garbage on the target area is sucked into the accommodation cavity 11 through the suction port 13.

[0136] The timing of increasing the operating power of the fan can be after, at the same time as, or before the driving of the movement of the cover 50 to reduce the opening size of the suction port 13. For example, after the movement of the cover 50 to reduce the opening size of the suction port 13, the sealing of the accommodation cavity 11 is better, i.e. a better vacuum degree is formed between the roller brush device 100 and the surface to be cleaned, and the fan can concentrate the suction force to suck the garbage on the surface to be cleaned corresponding to the suction port 13. If the operating power of the fan is increased at this time, the suction force generated will be greater, which can improve the suction efficiency of the fan on the garbage, thereby not only improving the cleaning effect, but also improving the cleaning efficiency.

[0137] Please refer to ​ In some embodiments, the method of controlling further comprises: 04. during at least part of the time period in which the cleaning device 1000 cleans the non-target area, controlling the driving assembly 70 to drive the movement of the roller brush 30 and / or the wiping member 61 of the cleaning device 1000 to clean the non-target area, and / or to drive the movement of the cover 50 to increase the opening size of the suction port 13.

[0138] Since the material of the non-target area is relatively hard and has a relatively small adsorption force on garbage (e.g., dust, hair, and debris), when the cleaning device 1000 cleans the non-target area, only a small adsorption force is needed to clean the garbage, and therefore, after the opening size of the suction port 13 is adjusted to a larger opening size for a period of time, the garbage on the target area is rolled up by the roller brush 30, and the garbage is effectively sucked into the dust box by the fan, which achieves a better cleaning effect and ensures cleaning efficiency.

[0139] Before the cleaning device 1000 cleans the non-target area, if the cleaning device 1000 is not in the target area, that is, the opening size of the suction port 13 is not adjusted, for example, the cleaning device 1000 travels from the non-target area A to the non-target area B, and for example, the cleaning device 1000 travels from the base station 3000 to the non-target area C, when the cleaning device 1000 cleans the non-target area, the opening size of the suction port 13 can not be adjusted. If the cleaning device 1000 travels from the target area to the non-target area for cleaning, the cover 50 is driven to move to increase the opening size of the suction port 13 during at least part of the time period when the cleaning device 1000 cleans the non-target area.

[0140] The cleaning mode of the cleaning device 1000 when cleaning the non-target area can include but is not limited to single sweeping, single mopping, simultaneous sweeping and mopping, sweeping first and then mopping, etc. In the above different cleaning modes, the operating states of the roller brush 30, the mopping member 61, and the side brush 60 are different, for example, only the mopping member 61 operates when only mopping, the roller brush 30 and the side brush 60 operate when only sweeping, and the roller brush 30, the mopping member 61, and the side brush 60 all operate when sweeping and mopping simultaneously. Therefore, at least one of the roller brush 30 and the mopping member 61 operates during at least part of the time period when the cleaning device 1000 cleans the non-target area.

[0141] In some embodiments, the timing of controlling the cover 50 to move to increase the opening size of the suction port 13 during the at least part of the time period when the cleaning device 1000 cleans the non-target area can be that part of the cleaning device 1000 has reached the non-target area, for example, the side brush 60 located in front of the traveling direction of the cleaning device 1000 can clean the non-target area, for example, the roller brush 30 located in the middle of the traveling direction of the cleaning device 1000 can clean the non-target area, for example, the sensor located at the left or right side of the traveling direction of the cleaning device 1000 can identify the non-target area; or the timing can be that the entire cleaning device 1000 has reached the non-target area, for example, the mop 61 located at the rear of the traveling direction of the cleaning device 1000 can clean the non-target area, for example, the sensor located at the tail of the traveling direction of the cleaning device 1000 can identify the non-target area. The timing of controlling the driving assembly 70 to drive the roller brush 30 and / or the mop 61 of the cleaning device 1000 to move to clean the non-target area can be before, at the same time as, or after controlling the cover 50 to move to increase the opening size of the suction port 13. For example, after controlling the cover 50 to move to decrease the opening size of the suction port 13, the operating power of the fan of the cleaning device 1000 is controlled to increase.

[0142] Referring to ​ In some embodiments, the step of driving the cover 50 to move to increase the opening size of the suction port 13 includes the step of: 041, driving the cover 50 to move so that the cover 50 is not in contact with the non-target area.

[0143] In some embodiments, the cover 50 is controlled to move to increase the opening size of the suction port 13 so that the cover 50 is not in contact with the non-target area, for example, the opening size of the suction port 13 can be the maximum opening degree. The step of adjusting the opening size of the suction port 13 to a larger opening degree includes the step of: the cover 50 is driven to move so that the cover 50 is not in contact with the non-target area. The cover 50 not being in contact with the non-target area can mean that the suction port 13 has multiple opening degrees, for example, the suction port 13 has the maximum opening degree, at this time, the cover 50 moves in the first direction X relative to the roller brush housing 10 to abut against the first limiting portion 15 and reaches the first position. Of course, the suction port 13 can also have any opening degree between the maximum opening degree and the minimum opening degree, that is, the cover 50 is kept at any position between the first limiting portion 15 and the second limiting portion 17.

[0144] and / or, referring to ​ In some embodiments, the control method further includes: 05, controlling the operating power of the fan of the cleaning device 1000 to decrease, the fan being in communication with the accommodation cavity 11, and during the operation of the fan, the garbage on the non-target area is sucked into the accommodation cavity 11 through the suction port 13.

[0145] When the cleaning device 1000 cleans the non-target area, only a small suction force is needed to clean up the garbage, not only can the opening size of the suction port 13 be adjusted to improve the cleaning efficiency, but also the running power of the fan can be reduced, the power consumption of the cleaning device 1000 can be reduced, and the endurance time can be improved.

[0146] Before the cleaning device 1000 cleans the non-target area, if it is not in the target area, for example, from the non-target area A to the non-target area B, and for example, from the base station 3000 to the non-target area C, when the cleaning device 1000 cleans the non-target area, the running power of the fan can be adjusted. If the cleaning device 1000 is driven from the target area (the running power of the fan is increased when cleaning the target area) to the non-target area for cleaning, the running power of the fan of the cleaning device 1000 is controlled to be reduced during at least part of the time period when the cleaning device 1000 cleans the non-target area. The timing of reducing the running power of the fan can be after, at the same time or before driving the cover body 50 to move to increase the opening size of the suction port 13. Exemplarily, after controlling the cover body 50 to move to increase the opening size of the suction port 13, the running power of the fan of the cleaning device 1000 is controlled to be reduced.

[0166] The processor 501 is used to analyze / process data and issue instructions to the execution mechanism (e.g., the driving assembly 70) or control the components of the execution mechanism on the control device 500. The control device 500 can further comprise a detector, which can be used to detect the type of the surface to be cleaned and the current opening degree of the suction port 13. The processor 501 can be in communication connection (wired or wireless) with the driving assembly 70 and the detector.

[0167] The present disclosure further provides a storage medium, which stores a computer program, and the computer program is used to implement the control method of any one of the above embodiments when executed by one or more processors 501.

[0168] For example, the computer program is executed by the processor 501, and the following control method is implemented:

[0169] During at least part of the time period in which the cleaning device 1000 cleans the target area, the cover 50 is controlled to move to reduce the opening size of the suction port 13, and the driving assembly 70 is controlled to drive the rolling brush 30 to rotate to clean the target area.

When it is required to clean larger-volume garbage, the cover 50 can move relative to the rolling brush housing 10 to increase the opening size of the suction port, so that the larger-volume garbage can enter the accommodation cavity 11 through the suction port 13. When it is required to clean the surface to be cleaned with a larger adsorption force, the cover 50 can move relative to the rolling brush housing 10 to reduce the opening size of the suction port 13, so that the sealing performance of the accommodation cavity 11 is better, and the rolling brush device 100 can concentrate the adsorption force to adsorb the garbage on the surface to be cleaned, and the cleaning effect of the rolling brush device 100 on the surface to be cleaned is better.

[0172] It should be noted that the "non-contact" described in the present disclosure can be that the cleaning device is placed on a relatively flat surface to be cleaned without contacting the surface to be cleaned. Here, some other states of contact are excluded, that is, the following states of contact cannot be regarded as contact, including but not limited to: the contact of the cleaning device with the obstacle or the surface to be cleaned caused by the up-and-down movement of the machine when the cleaning device is climbing over the obstacle; the contact of the cleaning device with the bottom surface of the base station caused by the ups and downs when the cleaning device is entering and exiting the base station; the contact caused by the up-and-down bumps of the machine when the cleaning device is walking on the uneven surface to be cleaned; the contact with the garbage caused by the relatively large or flying garbage on the surface to be cleaned, or the contact with the surface to be cleaned caused by the uneven part of the surface to be cleaned, etc. For example, when the cleaning device is placed on a relatively flat surface to be cleaned, the first side is not in contact with the surface to be cleaned, and the second side is in contact with the surface to be cleaned (for example, the first side is inclined relative to the second side, the second side is placed on the surface to be cleaned, and the first side is suspended above the surface to be cleaned); for another example, when the cleaning device is placed on a relatively flat non-target area, the cover body is not in contact with the non-target area (for example, the cover body is suspended above the non-target area); for another example, when the cleaning device is placed on a relatively flat target area, the cover body is in contact with the target area (for example, at least part of the cover body is in contact with the target area).
