DETAILED DESCRIPTION OF THE INVENTION

[0031] In order to clarify an objective, a technical solution and advantages of the present disclosure, the present disclosure will be further described in detail with the accompanying drawings. The described embodiments do not limit the present disclosure. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0032] In the following description, some embodiments denote a subset of all possible embodiments. However, it may be understood that some embodiments may be a same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0033] In the following description, the terms first, second, and third are used to distinguish similar objects, which do not indicate a specific order for the objects. It may be understood that a specific order or sequence indicated by first, second, and third may be interchanged if allowed, such that the embodiments of the present disclosure described here may be implemented in other orders than an order illustrated or described here.

[0034] Unless otherwise defined, all technical and scientific terms used here have the same meanings as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used here are merely for the purpose of describing the embodiments of the present disclosure, which are not intended to limit the present disclosure.

[0035] FIG. 1 and FIG. 2 are schematic structural diagrams of a roller brush assembly according to an example. As shown in FIG. 1 and FIG. 2, the roller brush assembly includes: [0036] a roller brush housing 1; [0037] a roller brush 2, located in the roller brush housing 1; and [0038] a magnetic detector 3, located on an outer surface of the roller brush housing 1 and configured to detect a magnetic signal; [0039] where the magnetic signal is configured to determine a type of the roller brush 2.

[0040] In some embodiments, the roller brush housing 1 may be understood as a roller brush enclosure The roller brush enclosure is capable of protecting the roller brush 2 arranged inside the roller brush enclosure.

[0041] In some embodiments, the roller brush 2 is detachably arranged in the roller brush housing 1. In this way, different types of roller brushes 2 may be replaced in the roller brush assembly as required.

[0042] In some embodiments, the specific type of the magnetic detector 3 may not be limited. For instance, the magnetic detector 3 may be an electromagnetic sensor. In this case, the magnetic detector 3 can detect the magnetic signals through electromagnetic induction. Alternatively, the magnetic detector 3 may be a Hall sensor. In this case, the magnetic detector 3 can detect the magnetic signals through a hall effect between a magnetic field and the Hall sensor.

[0043] In some embodiments, the type of roller brush 2 may be a first type. The first type of roller brush 2 may be provided with a magnetic member 4. The magnetic detector 3 may be configured to detect the magnetic signals for the first type of roller brush 2. The type of roller brush 2 may be a second type, where the second type of roller brush 2 may not be provided with the magnetic member 4. The magnetic detector 3 may be configured to detect no magnetic signal for the second type of roller brush 2. Here, the type of the roller brush 2 may be accurately identified as either the first type or the second type based on whether the magnetic signal is detected by the magnetic detector 3.

[0044] In the related art, different roller brushes installed in the cleaning device are generally not distinguished from each other. This makes it difficult for the cleaning device to provide corresponding product functions for different roller brushes, leading to a reduction in the diversity of product functions.

[0045] In the present disclosure, whether the magnetic signal may be generated by the roller brush 2 may be determined based on whether the magnetic signal is detected by the magnetic detector 3, such that a roller brush 2 capable of generating a magnetic signal can be distinguished from a roller brush 2 incapable of generating a magnetic signal.

[0046] Compared with the related art where the type of roller brush 2 installed in the roller brush assembly is not identified, in the present disclosure, the type of roller brush 2 arranged in the roller brush assembly can be precisely identified by detecting whether the arranged roller brush 2 can generate a magnetic signal. In this way, corresponding product functions can be provided for different types of roller brushes, thereby increasing the diversity of product functions.

[0047] In some embodiments, FIG. 3 is a schematic diagram of a partial structure of a roller brush assembly according to an example. With reference to FIG. 3, a roller brush 2 includes: [0048] a roller brush body 21, assembled in a roller brush housing 1; [0049] a magnetic member 4, arranged at an end of the roller brush body 21; and [0050] a magnetic detector 3, arranged at an end of the roller brush housing 1; [0051] where the end of the roller brush body 21 where the magnetic member 4 is arranged and the end of the roller brush housing 1 where the magnetic detector 3 is arranged are located at a same side.

[0052] In some embodiments, the roller brush 2 includes: bristles. The bristles may be located on an outer surface of the roller brush body 21. The roller brush 2 may achieve a cleaning function by means of the bristles on the roller brush body 21. Here, the shape of the bristles may not be limited.

[0053] In some embodiments, the roller brush body 21 may include a first end and a second end, and the roller brush housing I may include a first end and a second end. The first end of the roller brush body 21 and the first end of the roller brush housing 1 are located at the same side, and the second end of the roller brush body 21 and the second end of the roller brush housing 1 are located at the same side.

[0054] In some embodiments, the number of the magnetic member 4 may be one. In this case, the magnetic member 4 is arranged at the first end of the roller brush body 21, and the magnetic detector 3 may be arranged at the first end of the roller brush housing 1. Alternatively, the magnetic member 4 may be arranged at the second end of the roller brush body 21, and the magnetic detector 3 may be arranged at the second end of the roller brush housing 1.

[0055] In some other examples, the number of magnetic members 4 may be two. For instance, the magnetic members 4 may include a first magnetic member 41 and a second magnetic member 42. The magnetic detectors 3 may include a first magnetic detector 31 and a second magnetic detector 32. The first magnetic member 41 may be arranged at the first end of the roller brush body 21, and the second magnetic member 42 may be arranged at the second end of the roller brush body 21. The first magnetic detector 31 may be arranged at the first end of the roller brush housing 1, and the second magnetic detector 32 may be arranged at the second end of the roller brush housing 1.

[0056] In some embodiments, the magnetic member 4 may be any object capable of generating a magnetic signal. For instance, the magnetic member 4 may be any magnet capable of generating a magnetic field.

[0057] In some embodiments, any first type of roller brush 2 in the present disclosure includes: a roller brush body 21, assembled in a roller brush housing 1; and a magnetic member 4, arranged at an end of the roller brush body 21. In other words, only the first type of the roller brush 2 is provided with the magnetic member 4. In some other examples, the second type of roller brush 2 includes: a roller brush body 21, assembled in a roller brush housing 1. The roller brush body 21 is not provided with a magnetic member 4. In other words, there is no magnetic member 4 provided for the second type of roller brush 2.

[0058] In the present disclosure, since the end of the roller brush body 21 where the magnetic member 4 is arranged and the end of the roller brush housing 1 where the magnetic detector 3 is arranged are located at the same side, a distance between the magnetic member 4 and the magnetic detector 3 is short. In a case where the roller brush 2 is provided with the magnetic member 4, the magnetic detector 3 can reliably detect the magnetic signal from the magnetic member 4 at a close distance.

[0059] In some embodiments, the roller brush assembly includes: [0060] a driver, connected to the roller brush body 21 and configured to drive the roller brush body 21, along with the magnetic member 4, to rotate.

[0061] In some embodiments, the magnetic detector 3 is configured to generate a pulse signal in response to a magnetic pole of the magnetic member 4 approaching the magnetic detector 3 (as shown in FIG. 4). It should be noted that, the overall relative position of the magnetic member 4 and the magnetic detector 3 remains unchanged when the roller brush body 21 of the roller brush 2 along with the magnetic member 4 rotate. However, the positions of the magnetic poles of the magnetic member 4 relative to the magnetic detector 3 are changed.

[0062] In some embodiments, during one complete rotation of the magnetic member 4, the magnetic detector 3 generates a pulse signal when the south pole of the magnetic member 4 approaches the magnetic detector 3. Similarly, the magnetic detector 3 generates a pulse signal when the north pole of the magnetic member 4 approaches the magnetic detector 3. In other words, during one complete rotation of the magnetic member 4, the magnetic detector 3 generates two pulse signals. FIG. 4 illustrates a waveform of a pulse signal according to an example. Referring to FIG. 4, the number of pulse signals generated by the magnetic detector 3 is four, indicating that the magnetic member 4 has rotated twice. It can be understood that, in some application scenarios, the magnetic detector 3 is configured to generate a pulse signal upon detecting a magnetic signal.

[0063] In the present disclosure, a roller brush body 21 may be driven to rotate, which in turn causes the magnetic member 4 to rotate. In this case, in a rotation process of the magnetic member 4, the magnetic detector 3 may indicate whether the magnetic signal is detected by generating the pulse signal or not. In this way, a type of a roller brush 2 may be accurately identified even during the rotation process of the roller brush 2.

[0064] In some embodiments, FIG. 3, FIG. 5, and FIG. 6 are a schematic diagram of a partial structure of a roller brush assembly according to an example. Referring to FIG. 3, FIG. 5, and FIG. 6, a roller brush body 21 is provided with an accommodation cavity 211 and a slot 212 in communication with the accommodation cavity 211. A roller brush 2 further includes: [0065] a cutting assembly 22, which includes: a first blade 221 and a second blade 222 that are stacked, where the first blade 221 is fixedly connected to the roller brush body 21 at the slot 212, and the second blade 222 is slidably connected to the roller brush body 21 at the slot 212, and portions of the first blade 221 and the second blade 222 extend from the slot 212 to the accommodation cavity 211; and [0066] a linkage module 23, located in the accommodation cavity 211, where the linkage module 23 is configured to: drive the second blade 222 to slide relative to the first blade 221 in a first direction (with reference to an X1 direction in FIG. 5 and FIG. 6) while the roller brush body 21 rotates in a second rotation direction; and drive the second blade 222 to slide relative to the first blade 221 in the slot 212 in a second direction (with reference to an X2 direction in FIG. 5 and FIG. 6) opposite to the first direction while the roller brush body 21 rotates in a first rotation direction.

[0067] In some embodiments, the first rotation direction may be one of a clockwise direction and a counterclockwise direction, and the second rotation direction may be the other of the clockwise direction and the counterclockwise direction.

[0068] In the present disclosure, after the roller brush assembly is integrated into a cleaning device and the cleaning device performs cleaning work for a fixed time period, a certain amount of hair may tangle around the continuously rotating roller brush body 21, the cleaning device may control the roller brush 2 to cut the hair periodically. In a hair cutting period, the cleaning device may firstly control the roller brush body 21 to rotate in the second rotation direction, such that the linkage module 23 may drive the second blade 222 in the cutting assembly 22 to slide in the first direction relative to the first blade 221. The cleaning device may then control the roller brush body 21 to rotate in the first rotation direction, such that the linkage module 23 may drive the second blade 222 in the cutting assembly 22 to slide in the second direction relative to the first blade 221. Thus, while the cleaning device controls the roller brush 2 to cut the hair periodically, the second blade 222 in the cutting assembly 22 may slide back and forth relative to the first blade 221 in a length direction of the roller brush body 21, such that the cutting assembly 22 may better cut off the hair tangled around the roller brush body 21 and the cut hair may fall off from the roller brush body 21. Consequently, the cleaning device may clear the cut hair. This not only prevents issues with the driver in the cleaning device being blocked due to excessive hair tangling on the roller brush 2 but also eliminates the need for users to manually clean the hair from the roller brush 2. As a result, the service life of the cleaning device integrating such a roller brush 2 can be effectively extended and the cleaning performance of the cleaning device can be improved.

[0069] In some embodiments, FIG. 3, FIG. 5, and FIG. 6 are a schematic diagram of a partial structure of a roller brush assembly according to an example. With reference to FIG. 3, FIG. 5, and FIG. 6, a roller brush 2 includes a supporting rod 24, located in the accommodation cavity 211 and rotatably connected to the roller brush body 21. The supporting rod 24 includes: a threaded rod 242 provided with an external thread, a first polished rod 241 located in a first direction of the threaded rod 242, and a second polished rod 243 located in a second direction of the threaded rod 242.

[0070] A linkage module 23 includes: a clamping part 231 and an internal threaded hole. The linkage module 23 is clamped to the roller brush body 21 via the clamping part 231. The internal threaded hole is matched with the external thread. The linkage module 23 sleeves the supporting rod 24 via the internal threaded hole.

[0071] The linkage module 23 is configured to: move in the first direction when the roller brush body 21 rotates in a second rotation direction; and move in the second direction when the roller brush body 21 rotates in a first rotation direction.

[0072] In the present disclosure, by only arranging the linkage module 23 that can achieve axial movement through the rotation of the threaded rod 242, either by screwing in or unscrewing it, the second blade 222 can be driven to slide back and forth relative to the first blade 221. There is no need to additionally install a dedicated axial drive motor in the cleaning device to drive the second blade 222 to slide back and forth relative to the first blade 221. This approach effectively reduces the manufacturing cost of the cleaning device and saves space within the cleaning device that would otherwise be used for an axial drive motor and its associated transmission, resulting in a smaller overall volume and weight of the cleaning device.

[0073] In some embodiments, a magnetic member includes: a radially magnetized magnet; [0074] a magnetic detector includes: a Hall sensor, where the Hall sensor is arranged in a magnetization direction of the magnet.

[0075] It should be understood that the magnet on the roller brush body 21 and the Hall sensor on the roller brush housing I may be arranged in a same cross-section here, and the Hall sensor is located in the magnetization direction of the magnet in the cross-section. The cross-section may be a plane perpendicular to the rotation axis of the magnet. In this case, for each full rotation of the roller brush body 21, the Hall sensor may detect two square waves. By identifying the waveform, the type of roller brush 2 and the number of rotations can be detected.

[0076] In some embodiments, the magnetization direction of the magnet may differ from the rotation axis of the magnet.

[0077] In some embodiments, the shape of the magnet may not be limited. For instance, the shape of the magnet may be circular (as shown in FIG. 7), annular, rectangular, or irregular.

[0078] In the embodiment of the present disclosure, since the Hall sensor is arranged in the magnetization direction of the magnet, the Hall sensor can sensitively detect the number of times the magnetic poles of the magnet approach the Hall sensor during the rotation of the magnet, thereby determining the number of rotations of the magnet. This allows for precise identification of the number of rotations of the magnet.

[0079] In some embodiments, a cleaning device is provided according to the present disclosure. The cleaning device includes: [0080] the roller brush assembly according to any aspect of the present disclosure; and [0081] a processor, connected to the magnetic detector 3 and configured to determine a type of a roller brush 2 in the roller brush assembly based on whether a magnetic signal is detected by the magnetic detector 3 of the roller brush assembly.

[0082] In some embodiments, the cleaning device may be any intelligent device that can achieve a cleaning function by the roller brush 2. For instance, the cleaning device may be a robot vacuum cleaner/sweeping robot, which may achieve the cleaning function by the roller brush 2.

[0083] In some embodiments, the processor is configured to: determine the type of the roller brush 2 as a first type in response to determining that the magnetic signal is detected by the magnetic detector 3, and determine the type of the roller brush 2 as a second type in response to determining that the magnetic signal is not detected by the magnetic detector 3. The first type is different from the second type. The first type of roller brush 2 may be provided with a magnetic member 4. The second type of roller brush 2 may not be provided with the magnetic member 4. Here, the type of the roller brush 2 may be accurately identified as the first type or the second type based on whether the magnetic signal is detected by the magnetic detector 3.

[0084] In some embodiments, the first type of the roller brush 2 may be provided with the magnetic member 4, and the second type of the roller brush 2 may not be provided with the magnetic member 4. The processor may be configured to: determine that the roller brush 2 is provided with the magnetic member 4 and the type of the roller brush 2 is the first type in response to determining that the magnetic signal is detected by the magnetic detector 3; and determine that the roller brush 2 is not provided with the magnetic member 4 and the type of the roller brush 2 is the second type in response to determining that the magnetic signal is not detected by the magnetic detector 3.

[0085] In some embodiments, the magnetic detector 3 is configured to generate a pulse signal in response to detecting the magnetic signal, and the processor may be configured to determine the type of the roller brush 2 based on whether the pulse signal is received. The pulse signal may be a square wave signal (as shown in FIG. 4).

[0086] In the present disclosure, the processor connected to the magnetic detector 3 may determine whether the roller brush 2 can generate the magnetic signal based on the result of whether the magnetic signal is detected by the magnetic detector 3. In this way, the roller brush 2 capable of generating a magnetic signal can be distinguished from the roller brush 2 incapable of generating a magnetic signal. As a result, the type of the roller brush 2 mounted in the cleaning device can be accurately identified.

[0087] In some embodiments, the processor is configured to instruct the roller brush 2 to perform a cleaning function corresponding to the type of the roller brush 2; [0088] where, different types of roller brushes 2 correspond to different cleaning functions.

[0089] In some embodiments, different cleaning functions correspond to different cleaning parameters. The cleaning parameters may include at least one of a cleaning duration, a cleaning area, or a cleaning intensity. It is to be noted that different types of roller brushes 2 have different cleaning functions, which may be understood as follows: different types of roller brushes 2 have at least one different cleaning parameters of the cleaning duration, the cleaning area or the cleaning intensity.

[0090] In some embodiments, the roller brush 2 is provided with bristles, and different types of roller brushes 2 may correspond to different bristles. For instance, different types of roller brushes 2 may correspond to different bristle hardness. Different bristle hardness may correspond to different cleaning duration. For instance, the bristle hardness may be inversely related to the cleaning duration. Different bristle hardness may correspond to different cleaning areas. For instance, soft bristles may correspond to a wooden cleaning area, and hard bristles may correspond to a porcelain cleaning area. Different bristle hardness may correspond to different cleaning intensities. For instance, the bristle hardness may be inversely related to the cleaning intensity.

[0091] In some embodiments, the cleaning parameters may further include: a rotation direction and/or rotation time period of the roller brush 2. It can be understood that different types of roller brushes 2 have different cleaning functions, which may be understood as follows: different types of roller brushes 2 have different rotation directions and/or different rotation time periods. Here, the rotation time period may refer to total rotation time of the roller brush 2 in all rotation directions in a case where the cleaning function is performed by rotating the roller brush 2. In this case, any cleaning duration of the present disclosure may also be understood as the rotation time period here. Alternatively, the rotation time period may include independent rotation time of the roller brush 2 for rotating in each rotation direction. For instance, the rotation time period may include: a first rotation time period of the roller brush 2 for rotating in a first rotation direction and/or a second rotation time period of the roller brush 2 for rotating in a second rotation direction. The first rotation direction may be opposite to the second rotation direction. For instance, the rotation directions corresponding to any first type of roller brush 2 in the present disclosure may include the first rotation direction and the second rotation direction, and the rotation direction corresponding to any second type of roller brush in the present disclosure may include the first rotation direction.

[0092] In some embodiments, different types of roller brushes 2 may correspond to different bristle shapes. For instance, the bristle shape may be wavy, straight, or U-shaped. In this case, bristles of different shapes may correspond to different rotation directions and/or rotation time periods of the roller brush 2. For instance, the rotation direction corresponding to U-shaped bristles having an opening facing the second rotation direction may be the second rotation direction, and the rotation direction corresponding to wavy bristles may include the second rotation direction and/or the first rotation direction.

[0093] In the present disclosure, the corresponding cleaning function can be accurately performed by rapidly and accurately identifying the type of the roller brush 2.

[0094] In some embodiments, the processor is connected to a driver in the roller brush assembly, and is configured to determine a rotation direction and/or rotation time period of a roller brush body 21 based on the type of the roller brush 2 and generate a corresponding first driving signal; [0095] the driver is connected to the roller brush body 21 and the processor, and is configured to drive the roller brush body 21 along with a magnetic member 4 on the roller brush body 21 to rotate according to the rotation direction and/or the rotation time period based on the first driving signal.

[0096] In some embodiments, the processor is configured to determine, in response to determining that the type of the roller brush 2 is the first type, that the roller brush body 21 of the roller brush 2 rotates in the second rotation direction for predetermined time, followed by rotating in the first rotation direction by a predetermined number of rotations, and generate the corresponding first driving signal. The driver is connected to the roller brush body 21 and the processor, and is configured to drive, in a case where the type of the roller brush 2 is the first type, the roller brush body 21 along with the magnetic member 4 to rotate in the second rotation direction for the predetermined time based on the first driving signal and then rotate in the first rotation direction by the predetermined number of rotations. The roller brush 2 of the first type is provided with the magnetic member 4.

[0097] In some other examples, the processor is configured to determine, in response to determining that the type of the roller brush 2 is the second type, that the roller brush body 21 of the roller brush 2 constantly rotates in the first rotation direction for the predetermined time and generate the corresponding first driving signal. The driver is connected to the roller brush body 21 and the processor, and is configured to drive, in a case where the type of the roller brush 2 is the second type, the roller brush body 21 to constantly rotate in the second rotation direction based on the first driving signal. The roller brush 2 of the second type is not provided with the magnetic member 4. The driver may include an electric motor.

[0098] In the present disclosure, the corresponding first driving signal may be flexibly generated according to the type of the roller brush 2, and further the driver may be controlled to drive the roller brush body 21 to rotate according to an appropriate rotation direction and/or rotation time period based on the first driving signal corresponding to the type of the roller brush 2, thereby ensuring that a rotation state of the roller brush body 21 is suited to the type of the roller brush 2.

[0099] In some embodiments, the magnetic detector 3 is configured to generate a pulse signal in response to determining that a magnetic pole of the magnetic member 4 on the roller brush body 21 approaches the magnetic detector 3; [0100] the processor is configured to determine the number of rotations of the magnetic member 4 based on the pulse signal and generate a second driving signal based on the number of rotations; [0101] where the second driving signal is configured to adjust the rotation direction and/or the rotation time period of the roller brush body 21.

[0102] In some embodiments, the processor is configured to determine the number of rotations of the magnetic member 4 based on the number of pulse signals.

[0103] In some embodiments, in the first type of roller brush 2, the magnetic member 4 and the roller brush body 21 may be coaxially arranged. In other words, when the roller brush body 21 of the first type of roller brush 2 rotates, the magnetic member 4 may rotate synchronously with the roller brush body 21. In this case, the number of rotations of the magnetic member 4 is the number of rotations of the roller brush body 21. That is, the number of rotations, determined by the processor based on the number of pulse signals, of the magnetic member 4 may indicate the number of rotations of the roller brush body 21.

[0104] In some embodiments, the driver drives the roller brush body 21 to rotate according to the adjusted rotation direction and/or rotation time period based on the second driving signal.

[0105] In the present disclosure, the processor may accurately determine an actual number of rotations of the magnetic member 4 through the pulse signal generated by the magnetic detector 3. In other words, the processor may accurately determine an actual number of rotations of the roller brush body 21. In this way, after the actual number of rotations of the roller brush body 21 is determined, the rotation time period and/or the rotation direction of the roller brush body 21 may be adjusted in time according to the actual number of rotations of the roller brush body 21 in a case where the rotation state of the roller brush body 21 is required to be adjusted.

[0106] In some embodiments, the processor is configured to generate, in response to determining that the number of rotations during which the roller brush body 21 drives the magnetic member 4 to rotate in the first rotation direction reaches a predetermined number of rotations, the corresponding second driving signal to adjust the rotation direction of the roller brush body 21 to the second rotation direction. In some embodiments, in a case where the linkage module 23 in the roller brush assembly moves in a second direction, an internal threaded hole of the linkage module 23 may be clamped to an external thread on the threaded rod 242. The processor is configured to generate the corresponding second driving signal in response to determining that the number of rotations during which the roller brush body 21 drives the magnetic member 4 to rotate in the first rotation direction reaches the predetermined number of rotations, such that the rotation direction of the roller brush body 21 is adjusted to the second rotation direction, to drive the linkage module 23 to move in the first direction.

[0107] In some embodiments, in a case where the linkage module 23 moves in the first direction, the threaded rod 242 may be screwed out of the internal threaded hole of the linkage module 23 until the internal threaded hole moves to the first polished rod 241 for idling.

[0108] In the present disclosure, when the number of rotations during which the roller brush body 21 drives the magnetic member 4 to rotate in the first rotation direction reaches the predetermined number of rotations, i.e., when the linkage module 23 moves in the second direction, the corresponding second driving signal may be generated in time to adjust the rotation direction of the roller brush body 21 to the second rotation direction, causing the linkage module 23 moves in the first direction. In this way, the risk of the internal threaded hole of the linkage module 23 and the external threads on the threaded rod 242 becoming jammed due to excessive movement of the linkage module 23 in the second direction can be reduced. Further, it minimizes the situation where the linkage module 23 cannot continue moving, preventing it from driving the second blade 222 to move back and forth and achieve the cutting function, thereby ensuring the reliable implementation of the cutting function in the cleaning device.

[0109] It is to be noted that any detection method in the present disclosure may be applied to any cleaning device in the present disclosure.

[0110] FIG. 8 is a flow diagram of a detection method according to an example. As shown in FIG. 8, the method includes steps 81 and 82 as follows.

[0111] In step 81, whether a magnetic signal is detected by a magnetic detector is determined, where the magnetic detector is located on an outer surface of a roller brush housing of a cleaning device.

[0112] In some embodiments, whether the magnetic signal is detected by the magnetic detector may be determined according to a first predetermined period. Alternatively, whether the magnetic signal is detected by the magnetic detector may be determined in real-time. The first predetermined period may be determined based on a replacement frequency of replacing a roller brush in a cleaning device. The first predetermined period may be inversely related to the replacement frequency.

[0113] In some embodiments, the magnetic detector may be configured to detect the magnetic signal according to a second predetermined period. Alternatively, the magnetic detector may be configured to detect the magnetic signal. The second predetermined period may be determined based on a replacement frequency of replacing a roller brush in a cleaning device. The second predetermined period may be inversely related to the replacement frequency.

[0114] In some embodiments, the first predetermined period may be the same as the second predetermined period. Alternatively, the first predetermined period may be longer than the second predetermined period.

[0115] In some embodiments, in response to a triggering instruction, the magnetic signal may be detected by the magnetic detector, and/or whether the magnetic signal is detected by the magnetic detector may be determined. The triggering instruction may be an instruction generated in response to detecting a touch operation for a predetermined control. Alternatively, the triggering instruction may be an instruction generated in response to detecting predetermined voice information. The predetermined voice information may be configured to instruct that the magnetic signal is detected.

[0116] In step 82, a type of a roller brush mounted in the roller brush housing is determined based on whether the magnetic signal is detected by the magnetic detector.

[0117] In some embodiments, in response to determining the type of the roller brush, detection of the magnetic signal by the magnetic detector may be stopped. Here, after the type of the roller brush is determined, continuous detection of the magnetic signal by the magnetic detector may be stopped in time. In this way, power consumption of the magnetic detector can be reduced.

[0118] In the example of the present disclosure, types of different roller brushes may be accurately identified based on whether the magnetic signal is detected by the magnetic detector. As a result, operations can be performed corresponding to different types of roller brushes.

[0119] In some embodiments, the type of the roller brush mounted in the roller brush housing is determined based on whether the magnetic signal is detected by the magnetic detector, which includes: [0120] the type of the roller brush is determined as a first type in response to determining that the magnetic signal is detected by the magnetic detector; or [0121] the type of the roller brush is determined as a second type in response to determining that the magnetic signal is not detected by the magnetic detector, where the first type is different from the second type.

[0122] In the present disclosure, whether the type of the roller brush is the first type or the second type may be accurately determined based on whether the magnetic signal is detected by the magnetic detector, such that an accurate type of roller brush can be suitable for performing the appropriate related operation.

[0123] In some embodiments, the method further includes: [0124] controlling the roller brush to perform a cleaning function corresponding to the type of the roller brush, [0125] where different types of roller brushes correspond to different cleaning functions.

[0126] In some embodiments, different cleaning functions correspond to different cleaning parameters. The cleaning parameters may indicate at least one of the following: cleaning duration, a cleaning area, or a cleaning intensity. It may be understood that different types of roller brushes have different cleaning functions, which may be understood as follows: different types of roller brushes have at least one of the different cleaning duration, different cleaning area or different cleaning intensity.

[0127] In some embodiments, the roller brush is provided with bristles, and different types of roller brushes may correspond to different bristles. For instance, different types of roller brushes may correspond to different bristle hardness. Different bristle hardness may correspond to different cleaning duration. For instance, the bristle hardness may be inversely related to the cleaning duration. Different bristle hardness may correspond to different cleaning areas. For instance, soft bristles may correspond to a wooden cleaning area, and hard bristles may correspond to a porcelain cleaning area. Different bristle hardness may correspond to different cleaning intensities. For instance, the bristle hardness may be inversely related to the cleaning intensity.

[0128] In some embodiments, the cleaning parameters may further indicate: a rotation direction and/or rotation time period of the roller brush. It can be understood that different types of roller brushes have different cleaning functions, which may be understood as follows: different types of roller brushes have different rotation directions and/or different rotation time periods. Here, the rotation time period may refer to total rotation time of the roller brush in all rotation directions in a case where the cleaning function is performed by rotating the roller brush. In this case, any cleaning duration of the present disclosure may also be understood as the rotation time period here. Alternatively, the rotation time period may include independent rotation time of the roller brush for rotating in each rotation direction. For instance, the rotation time period may include: a second rotation time period of the roller brush for rotating in a second rotation direction and/or a first rotation time period of the roller brush for rotating in a first rotation direction. The second rotation direction may be opposite to the first rotation direction.

[0129] In some embodiments, different types of roller brushes may correspond to different bristle shapes. For instance, the bristle shape may be wavy, straight, or U-shaped. In this case, bristles of different shapes may correspond to different rotation directions and/or rotation time periods of the roller brush. For instance, the rotation direction corresponding to U-shaped bristles having an opening facing the second rotation direction may be the second rotation direction, and the rotation direction corresponding to wavy bristles may include the second rotation direction and/or the first rotation direction.

[0130] In the present disclosure, the corresponding cleaning function can be accurately performed by rapidly and accurately identifying the type of the roller brush, to ensure a desirable cleaning performance of the cleaning device.

[0131] In some embodiments, controlling the roller brush to perform a cleaning function corresponding to the type of the roller brush includes: [0132] determining a rotation direction and/or a rotation time period of a roller brush body of the roller brush based on the type of the roller brush, where the roller brush body is assembled in the roller brush housing of the cleaning device; [0133] generating a first driving signal based on the rotation direction and/or the rotation time period; and [0134] driving the roller brush body along with a magnetic member to rotate according to the rotation direction and/or the rotation time period based on the first driving signal.

[0135] In some embodiments, a mapping relationship table among a type of the roller brush, a rotation direction and a rotation time period may be established in advance.

[0136] In some embodiments, after the type of the roller brush is determined, the rotation direction and/or the rotation time period corresponding to the type of the roller brush may be determined from the mapping relationship table based on the type of the roller brush.

[0137] In the present disclosure, the corresponding first driving signal may be flexibly generated according to the type of the roller brush, and further the roller brush body may be driven to rotate according to an appropriate rotation direction and/or rotation time period based on the first driving signal corresponding to the type of the roller brush. This ensure that the rotation state of the roller brush body can be suitable to the type of the roller brush.

[0138] In some embodiments, the method further includes: generating, in a case where the roller brush body of the roller brush rotates and the roller brush body is provided with a magnetic member, a pulse signal in response to determining that a magnetic pole of the magnetic member approaches the magnetic detector; [0139] determining a number of rotations of the magnetic member based on the pulse signal; [0140] generating a second driving signal based on the number of rotations; and [0141] adjusting a rotation direction and/or a rotation time period based on the second driving signal.

[0142] It should be understood that the magnetic detector generates a pulse signal only when the roller brush body rotates and the roller brush is provided with the magnetic member, i.e., the roller brush is of the first type with a magnetic member. In this case, the cleaning device can determine the number of rotations of the magnetic member based on the pulse signal. In a case where the roller brush is of the second type without a magnetic member, there is no need to determine the number of rotations of the magnetic member.

[0143] In some embodiments, determining the number of rotations of the magnetic member based on the pulse signal, includes: determining the number of rotations of the magnetic member based on the number of pulse signals. It is to be noted that the overall relative position of the magnetic member and the magnetic detector remains unchanged when the roller brush body of the roller brush along with the magnetic member rotate. Rather, the positions of the magnetic poles of the magnetic member relative to the magnetic detector are changed. During one complete rotation of the magnetic member, the magnetic detector generates a pulse signal when the south pole of the magnetic member approaches the magnetic detector. Similarly, the magnetic detector generates a pulse signal when the north pole of the magnetic member approaches the magnetic detector. In other words, during one complete rotation of the magnetic member, the magnetic detector generates two pulse signals. In this case, the number of rotations of the magnetic member may be accurately determined based on the number of pulse signals.

[0144] In some embodiments, the second driving signal includes at least one of the following: [0145] a first driving sub-signal, configured to adjust the rotation direction to the first rotation direction and/or adjust the rotation time period from the second rotation time period to the first rotation time period, where the second rotation time period is a preset rotation time period for driving the roller brush body to rotate in the second rotation direction; and [0146] a second driving sub-signal, configured to adjust the rotation direction to the second rotation direction and/or adjust the rotation time period from the first rotation time period to the second rotation time period, where the first rotation time period is a preset rotation time period for driving the roller brush body to rotate in the first rotation direction.

[0147] In some embodiments, determining the rotation direction and/or the rotation time period based on the type of the roller brush includes: [0148] determining, in a case where the type of the roller brush is the first type, that the roller brush body of the roller brush rotates cyclically according to the second rotation direction and the first rotation direction, to cut entanglements on the roller brush body by driving a second blade arranged in a slot of the roller brush body to slide back and forth relative to a first blade.

[0149] Here, in a case where the roller brush arranged in the cleaning device is the first type of roller brush, the roller brush body may be controlled to rotate cyclically according to the second rotation direction and the first rotation direction, to drive the second blade arranged in the slot of the roller brush body to slide back and forth relative to the first blade to cut the entanglements on the roller brush body. In this way, the hair tangled around the roller brush body can be cut off, and the cut hair can fall off from the roller brush body. Consequently, the cleaning device can clear the cut hair. This not only prevents issues with the driver in the cleaning device being blocked due to excessive hair tangling on the roller brush but also eliminates the need for users to manually clean the hair from the roller brush. As a result, the service life of the cleaning device integrating such a roller brush can be effectively extended and the cleaning performance of the cleaning device can be improved.

[0150] In some embodiments, generating the second driving signal based on the number of rotations includes at least one of the following steps: [0151] generating a first driving sub-signal in response to determining that the number of rotations, during which the roller brush body rotates in the second rotation direction, reaches a first number of rotations; or [0152] generating a second driving sub-signal in response to determining that the number of rotations, during which the roller brush body rotates in the first rotation direction, reaches a second number of rotations. Here, the first number of rotations and the second number of rotations may be set according to actual rotation requirements in each rotation direction. The first number of rotations and the second number of rotations may be the same or not.

[0153] In the present disclosure, the processor may accurately determine an actual number of rotations of the magnetic member through the pulse signal generated by the magnetic detector. In other words, the processor may accurately determine an actual number of rotations of the roller brush body. In this way, after the actual number of rotations of the roller brush body is determined, the rotation time period and/or the rotation direction of the roller brush body may be adjusted in time according to the actual number of rotations of the roller brush body in a case where the rotation state of the roller brush body is required to be adjusted.

[0154] In some embodiments, determining the rotation direction and/or the rotation time period based on the type of the roller brush includes: [0155] determining, in response to determining that the type of the roller brush is the first type, that the roller brush body of the roller brush rotates in the second rotation direction for a predetermined time period, followed by rotating in the first rotation direction by a predetermined number of rotations; or [0156] determining, in response to determining that the type of the roller brush is the second type, that the roller brush body constantly rotates in the second rotation direction.

[0157] In some embodiments, the first type of roller brush in the present disclosure may be a roller brush provided with a cutting assembly. The first type of roller brush may cut the entanglements on the roller brush body through sliding of the second blade in the cutting assembly relative to the first blade. In other words, the first type of roller brush may be a hair-cutting roller brush with a hair-cutting function. The second type of roller brush may be an ordinary roller brush without a cutting assembly.

[0158] In some embodiments, in response to determining that the type of the roller brush is the first type, it is determined that the roller brush body of the roller brush rotates in the second rotation direction for the predetermined time and then rotates in the first rotation direction by the predetermined number of rotations, to drive the second blade arranged in the slot of the roller brush body to slide in a second direction relative to the first blade, to cut the entanglements on the roller brush body.

[0159] In some embodiments, determining the number of rotations of the magnetic member based on the pulse signal includes: determining the number of rotations of the magnetic member based on the pulse signal, in response to determining that the roller brush body of the roller brush rotates in the second rotation direction for the predetermined time period followed by rotating in the first rotation direction by the predetermined number of rotations. The second driving signal is generated based on the number of rotations, which includes: generating a second driving sub-signal in response to determining that the number of rotations, during which the roller brush body rotates in the first rotation direction, reaches the second number of rotations, where the second driving sub-signal is configured to adjust the rotation direction from the first rotation direction to the second rotation direction.

[0160] In some other examples, in response to determining the roller brush body constantly rotates in the second rotation direction, the number of rotations of the magnetic member is not determined based on the pulse signal.

[0161] In the present disclosure, in a case where the roller brush arranged in the cleaning device is the first type of roller brush, the roller brush body may be controlled to rotate cyclically according to the second rotation direction and the first rotation direction, to drive the second blade arranged in the slot of the roller brush body to slide back and forth relative to the first blade in the second direction to cut the entanglements on the roller brush body. In this way, the hair tangled around the roller brush body can be cut off, and the cut hair can fall off from the roller brush body. Consequently, the cleaning device can clear the cut hair. This not only prevents issues with the driver in the cleaning device being blocked due to excessive hair tangling on the roller brush but also eliminates the need for users to manually clean the tangled hair from the roller brush. As a result, the service life of the cleaning device integrating such a roller brush can be effectively extended and the cleaning performance of the cleaning device can be improved.

[0162] In some embodiments, determining the number of rotations of the magnetic member based on the pulse signal includes: [0163] determining, in a case where the roller brush body of the roller brush rotates in the first rotation direction, the number of rotations, during which the magnetic member rotates in the first rotation direction, based on the pulse signal; and [0164] generating the second driving signal based on the number of rotations includes: [0165] generating the second driving signal in response to determining that the number of rotations reaches the predetermined number of rotations, where the second driving signal is configured to adjust the rotation direction to the second rotation direction.

[0166] In some embodiments, in a case where the roller brush body of the roller brush rotates in the first rotation direction, any linkage module of the present disclosure may move in the second direction, and the internal threaded hole of the linkage module may be clamped to the external thread on any threaded rod of the present disclosure. Here, in a case where the roller brush body of the roller brush rotates in the first rotation direction, i.e., while the linkage module moves in the second direction, the corresponding second driving signal may be generated in time to adjust the rotation direction of the roller brush body to the second rotation direction, enabling the linkage module to move in the first direction. In this way, the risk of the internal threaded hole of the linkage module and the external threads on the threaded rod becoming jammed due to excessive movement of the linkage module in the second direction can be reduced. Further, it minimizes the situation where the linkage module cannot continue moving, preventing it from driving the second blade to move back and forth and achieve the cutting function, thereby ensuring the reliable implementation of the cutting function in the cleaning device.

[0167] In some embodiments, in a case where the roller brush body rotates in the second rotation direction, detection of the magnetic signal by the magnetic detector and/or generation of the pulse signal by the magnetic detector may be stopped. Here, on the premise of ensuring that the internal threaded hole of the linkage module and the external threads on the threaded rod are not stuck, resource consumption caused by continuous long-term detection of the magnetic signal and/or generation of the pulse signal by the magnetic detector can be reduced.

[0168] For better understanding of the technical solution of the present disclosure, reference is made to FIG. 9. FIG. 9 is a schematic flowchart of a detection method according to an example. The method includes steps 91 to 97 as follows.

[0169] In step 91, whether a magnetic signal is detected by a magnetic detector is determined.

[0170] In step 92, a type of a roller brush is determined as a first type in response to determining that the magnetic signal is detected by the magnetic detector; [0171] where the first type of the roller brush may be understood as a hair-cutting roller brush.

[0172] In step 93, in response to determining that the type of the roller brush is the first type, it is determined that a roller brush body of the roller brush rotates in a second rotation direction for predetermined time followed by rotating in a first rotation direction by a predetermined number of rotations, where the second rotation direction is opposite to the first rotation direction.

[0173] In step 94, in a case where the roller brush body of the roller brush rotates in the first rotation direction, the magnetic detector is used to detect whether the number of rotations of a magnetic member arranged on the roller brush body reaches the predetermined number of rotations.

[0174] In step 95, in response to determining that the number of rotations of the magnetic member reaches the predetermined number of rotations, a rotation direction of the roller brush body is adjusted to the second rotation direction.

[0175] In step 96, the type of the roller brush is determined as a second type in response to determining that the magnetic signal is not detected by the magnetic detector;

[0176] where the second type of the roller brush may be understood as an ordinary roller brush without a hair-cutting function.

[0177] In step 97, in response to determining that the type of the roller brush is the second type, it is determined that the roller brush body constantly rotates in the second rotation direction.

[0178] The technical solution according to the embodiments of the present disclosure can have the beneficial effects below.

[0179] In the present disclosure, since whether the magnetic signal may be generated by the roller brush can be determined based on whether the magnetic signal is detected by the magnetic detector, a roller brush capable of generating a magnetic signal can be distinguished from a roller brush incapable of generating a magnetic signal, and further the type of the roller brush can be determined.

[0180] Compared with the related art where the type of a roller brush mounted in a roller brush assembly is not identified, in the present disclosure, the type of the roller brush mounted in the roller brush assembly can be accurately identified by detecting whether the magnetic signal is generated by the roller brush mounted in the roller brush assembly. In this way, product functions can be provided corresponding to different roller brushes, thereby improving the diversity of the product functions.
