Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to cleaning components and cleaning equipment. Background Technology

[0002] With the rapid development of smart home technology, cleaning equipment (such as robotic vacuum cleaners), as core devices for improving household cleaning efficiency and reducing users' workload, has been widely used in various scenarios such as homes and offices. In actual use, floor materials are diverse. In addition to common hard floors (such as tiles and wood floors), carpets, due to their advantages such as anti-slip properties, noise reduction, and improved spatial comfort, have also become an important part of the flooring in many indoor environments. This places higher demands on the carpet cleaning capabilities of cleaning equipment.

[0003] Existing cleaning equipment typically features a side-sweeping brush structure. Its main function is to use high-speed rotation to gather dust, debris, and other impurities from the sides and corners of the machine towards the suction port for subsequent collection, thereby expanding the cleaning coverage and improving overall cleaning efficiency. However, side-sweeping brushes have drawbacks. They can cause dirt to come into contact with clean surfaces or create significant resistance when cleaning soft materials like carpets, affecting cleaning efficiency. This problem stems from the combined effects of the side-sweeping brush's structural characteristics and gravity. Utility Model Content

[0004] Therefore, it is necessary to provide a cleaning component for use in cleaning equipment to address the above problems.

[0005] A cleaning component includes:

[0006] A brush assembly includes a connecting portion and a bristle portion. The bristle portion includes one or more bristles connected to the connecting portion. The connecting portion is used to connect to a drive mechanism of a cleaning device. The drive mechanism is configured to drive the brush assembly to rotate.

[0007] The lifting mechanism is configured to drive the bristle portion to move relative to the connecting portion, so as to raise the ends of the bristles away from the connecting portion in the height direction of the cleaning equipment.

[0008] In one embodiment, the lifting mechanism includes:

[0009] The first magnetic component is used to be mounted on the body of the cleaning equipment;

[0010] The second magnetic component is disposed on the bristle section;

[0011] The first magnetic attractor is configured as an electromagnet, and the second magnetic attractor is a magnetic reaction element. The first magnetic attractor and the second magnetic attractor generate a magnetic attraction force to make the brush bristles move toward the body of the cleaning device.

[0012] In one embodiment, the lifting mechanism includes:

[0013] Clamping plate, which is rotatably mounted on the body of the cleaning equipment;

[0014] The first driving component is disposed on the machine body and drives the clamping plate to rotate relative to the machine body.

[0015] When the first driving member drives the clamping plate to rotate away from the body, a clamping space is formed between the clamping plate and the bottom surface of the body, which is suitable for capturing the bristles; when the first driving member drives the clamping plate to rotate towards the body, the clamping plate causes the bristles to move towards the side where the body is located.

[0016] In one embodiment, the first driving element is configured as an electromagnet, and a magnetic reaction element is mounted on the clamping plate. When the first driving element and the clamping plate generate a magnetic attraction force, the clamping plate can be rotated towards one side of the machine body; or...

[0017] The first driving component is configured as a drive motor, and the first driving component is connected to the clamping plate to drive the clamping plate to rotate toward the side of the machine body or away from the side of the machine body.

[0018] In one embodiment, the lifting mechanism includes:

[0019] A second driving member and at least one tray are provided. The second driving member is disposed at the connecting part, and the tray is drivenly connected to the second driving member. In the height direction of the cleaning device, the tray is located below the bristle part. The second driving member drives the tray to swing upward, so that the tray drives the bristles to move relative to the connecting part.

[0020] Alternatively, the raising mechanism includes:

[0021] A third drive member and at least one gripper are provided on the body of the cleaning device. The third drive member drives the gripper to grasp the bristle portion, causing the bristles to move relative to the connecting portion toward the body.

[0022] In one embodiment, the cleaning assembly further includes a position monitoring assembly, which includes a monitor and an identification element. The monitor is disposed on the body of the cleaning device, and the identification element is disposed on a brush. The monitor identifies the relative position of the brush to the body by monitoring the identification element.

[0023] In one embodiment, the bristles are made of a flexible material.

[0024] In one embodiment, the bristles include a solid segment and a movable segment, one end of the solid segment being fixedly connected to a connecting portion, and the movable segment being rotatably connected to the other end of the solid segment.

[0025] In one embodiment, the bristle portion further includes at least one connector that connects at least two bristles.

[0026] This application further proposes a cleaning device, which includes a body and the cleaning components described in some of the above embodiments.

[0027] The aforementioned cleaning components, with the lifting mechanism driving the bristle tips to rise, can prevent the bristles from contacting the work surface and significantly reduce the depth of the bristles penetrating the carpet fibers. This prevents the cleaning equipment from re-contaminating the clean floor and avoids problems such as jamming or deviation of the movement path on the carpet. On the other hand, the contact area and friction intensity between the bristles and the carpet fibers are significantly reduced, which can effectively slow down the wear rate of the bristles and greatly extend the service life of the brush components.

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] In its natural state, the bristles of a side-sweeping brush hang down. When the cleaning equipment sweeps the carpet surface, the hanging bristles directly penetrate into the gaps between the carpet fibers. Since the carpet fibers themselves provide resistance, this penetration not only hinders the normal rotation of the side-sweeping brush but also impedes the movement of the cleaning equipment. Furthermore, it causes prolonged friction between the brush bristles and the carpet, resulting in brush wear. After the side-sweeping brush becomes dirty, its re-contact with the floor will soil the floor. To avoid these issues and solve related problems, this application provides a cleaning component applicable to a cleaning equipment 100, including a brush component 1 and a lifting mechanism, for example, see [reference needed]. Figures 1 to 5 As shown, this application uses the application of the cleaning component in a cleaning device 100 (e.g., a robotic vacuum cleaner) as an example for illustration.

[0042] The brush component 1 includes a connecting portion 11 and a bristle portion 12. The bristle portion 12 includes one or more bristles 121 connected to the connecting portion 11. The connecting portion 11 is used to connect to the drive mechanism of the cleaning device 100. The drive mechanism is configured to drive the brush component 1 to rotate. The rotation of the brush component 1 gathers dust and debris on the ground. When the cleaning device 100 encounters a flexible and thick surface such as a carpet during cleaning, the lifting mechanism is activated, thereby applying a force to the bristle portion 12, causing the angle of the bristle portion 12 relative to the connecting portion 11 to change. This raises the ends of the bristles 121, which were originally hanging down naturally, reducing the depth to which the bristles 121 penetrate into the gaps in the carpet fibers.

[0043] As the lifting mechanism drives the tip of the bristles 121 to rise, the depth to which the bristles 121 penetrate the carpet pile is greatly reduced. This not only avoids the cleaning equipment 100 from getting stuck or deviating from its movement path on the carpet, but also significantly reduces the contact area and friction intensity between the bristles 121 and the carpet pile, effectively slowing down the wear rate of the bristles 121 and greatly extending the service life of the brush 1.

[0044] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the lifting mechanism includes a first magnetic chuck 21 and a second magnetic chuck 22. The first magnetic chuck 21 is disposed on the body 101 of the cleaning device 100, and the second magnetic chuck 22 is disposed on the bristle portion 12. The first magnetic chuck 21 is configured as an electromagnet, and the second magnetic chuck 22 is a magnetic reaction element. The first magnetic chuck 21 and the second magnetic chuck 22 generate a magnetic attraction force, causing the bristles 121 to move toward the first magnetic chuck 21, that is, toward the body (101) of the cleaning device (100).

[0045] For example, in some embodiments of this application, multiple first magnetic members 21 and second magnetic members 22 are configured. Multiple first magnetic members 21 are disposed on the body 101 and are evenly arranged along the circumference of the brush member 1. Each bristle 121 is provided with one second magnetic member 22, and in the height direction of the cleaning device 100, each second magnetic member 22 is adapted to correspond one-to-one with each first magnetic member 21. Each first magnetic member 21 is used to magnetically engage with its corresponding second magnetic member 22 to cause the brush bristle 121 with the second magnetic member 22 to move.

[0046] When the cleaning device 100 is cleaning the tile floor in the living room, all the first magnetic components 21 are de-energized and do not generate magnetic force. At this time, each bristle 121 with a second magnetic component 22 hangs down naturally under its own weight, with the ends of the bristles 121 pressed tightly against the ground. When the drive mechanism rotates the brush component 1, the brush component 1 sweeps dust and debris on the ground towards the suction port. However, when the cleaning device 100 slowly approaches the carpet, the control system of the cleaning device 100 energizes the first magnetic components 21. After being energized, the first magnetic components 21 and the second magnetic components 22 instantly generate magnetic force. Under the pull of the magnetic force, the second magnetic component 22 causes the bristles 121 to deflect towards the corresponding first magnetic component 21, so that the ends of the bristles 121 are raised. After the cleaning device 100 leaves the carpet and returns to the tile floor, the control system of the cleaning device 100 de-energizes all the first magnetic components 21, and the magnetic force disappears. Under the influence of gravity, the bristles 121 resume their natural drooping, and the tips of the bristles 121 once again press against the ground, continuing to efficiently clean the tile floor.

[0047] CombinationFigures 3 to 5 As shown, in one embodiment of this application, the lifting mechanism includes a clamping plate 23 and a first driving member 24. The clamping plate 23 is rotatably disposed on the body 101 of the cleaning device 100. The first driving member 24 is disposed on the body 101. The first driving member 24 drives the clamping plate 23 to rotate relative to the body 101. When the first driving member 24 drives the clamping plate 23 to rotate away from the body 101, a clamping space 25 is formed between the clamping plate 23 and the bottom surface of the body 101. The clamping space 25 is suitable for capturing the bristle part 12. When the first driving member 24 drives the clamping plate 23 to rotate toward the body 101, the clamping plate 23 drives the bristles 121 to move toward the body 101.

[0048] For example, in some embodiments of this application, when the cleaning device 100 is cleaning a normal floor such as a tiled floor in the living room or a wooden floor in the bedroom, the clamping plate 23 remains in its initial position against the bottom of the body 101. At this time, all the bristles 121 hang down naturally under their own weight, with the ends of the bristles 121 tightly against the ground. The drive mechanism of the cleaning device 100 drives the brush 1 to rotate, and the rotating bristles 121 can efficiently sweep dust and debris on the ground towards the suction port of the device, achieving thorough cleaning. However, when the sensor of the cleaning device 100 detects a carpet in front (such as when the body 101 encounters an obstacle) and slowly approaches the carpet, the control system of the cleaning device 100 immediately sends a signal to the first drive member 24. This drives the clamping plate 23 to rotate towards the ground, so that a clamping space 25 adapted to the size of the bristle part 12 is formed between the clamping plate 23 and the bottom of the body 101.

[0049] As the brush 1 continues to rotate, the rotating bristle portion 12 moves into the clamping space 25, completing the capture of the bristle portion 12. Subsequently, the control system detects that the bristle portion 12 has entered the clamping space 25, and then sends a direction switching command to the first drive member 24, driving the clamping plate 23 to rotate towards the machine body 101. The clamping plate 23 applies an upward force through contact with the bristle portion 12, causing the bristle portion 12 to deflect at an angle relative to the connecting portion 11, ultimately raising the end of the bristle 121 away from the connecting portion 11, reducing the depth of insertion into the gaps of the carpet pile.

[0050] When the cleaning device 100 leaves the carpet area and returns to a normal floor such as tile or wood flooring, the control system of the cleaning device 100 controls the first drive component 24 to drive the clamping plate 23 to rotate towards the ground, so that the clamping plate 23 releases the brush part 12; at the same time, the drive mechanism of the cleaning device 100 drives the brush part 1 to rotate in the opposite direction, so that the brush part 12 moves out of the clamping space 25 defined by the clamping plate 23 and the machine body 101. The brush 121 returns to its natural hanging state under its own gravity, and the ends of the brush 121 are pressed against the ground again to continue to clean the normal floor efficiently; after the brush part 12 moves out of the clamping space 25, the first drive component 24 drives the clamping plate 23 to return to the initial position of being in contact with the bottom of the machine body 101.

[0051] Combination Figures 3 to 5 As shown, in one embodiment of this application, the first driving member 24 is configured as an electromagnet, and the clamping plate 23 includes a magnetic reactive element. The magnetic reactive element is a material capable of generating a magnetic reaction with the electromagnet (such as an ferrous metal part or a composite part with a built-in magnetic core). Through the magnetic attraction force generated between the first driving member 24 (electromagnet) and the clamping plate 23, the clamping plate 23 is directly driven to rotate toward the side where the body 101 is located. In some examples, the material of the clamping plate 23 is a magnetic reactive element. In other examples, a magnetic reactive element can be installed on the clamping plate to achieve the same function.

[0052] Specifically, when the cleaning device 100 cleans ordinary floors (such as tile floors or wooden floors), the first driving component 24 (electromagnet) is energized, and a stable magnetic attraction force is generated between the first driving component 24 (electromagnet) and the clamping plate 23. For example... Figure 3 As shown, the magnetic attraction direction is towards the first driving member 24 (i.e., one side of the body 101), which can firmly attach the clamp 23 to the bottom of the body 101, so that the clamp 23 is kept in the initial position of being in contact with the bottom of the body 101.

[0053] At this time, the bristles 121 hang down naturally under their own gravity, and the ends of the bristles 121 are tightly attached to the ground. The drive mechanism of the cleaning device 100 drives the brush 1 to rotate. The rotating bristles 121 can efficiently sweep the dust and debris on the ground towards the suction port, ensuring the cleaning effect of ordinary floors. At the same time, the magnetic attraction generated by the power can prevent the clamp 23 from falling out of its initial position due to the vibration of the device movement, thus improving the structural stability.

[0054] When the sensor of the cleaning device 100 detects that there is a carpet in front and the brush bristles 121 need to be raised, the control system first sends a signal to the first drive component 24, weakening the magnetic attraction between the first drive component 24 and the clamping plate 23, making it insufficient to completely attract the clamping plate 23. Figure 4As shown, the clamping plate 23 rotates to the side away from the body 101 (towards the ground) under its own gravity, forming a clamping space 25 between the clamping plate 23 and the bottom of the body 101 that is adapted to the size of the brush bristle part 12. Since the brush part 1 continues to rotate, the brush bristle part 12 will move into the clamping space 25, completing the clamping plate 23's capture of the brush bristle part 12.

[0055] Once the control system confirms through monitoring that the bristle section 12 has entered the clamping space 25, it immediately sends a signal to the first drive member 24, causing the first drive member 24 to generate a stronger magnetic attraction. Under the pull of the magnetic attraction, the clamping plate 23 quickly rotates towards the side of the machine body 101, applying an upward force through contact with the bristle section 12, causing the bristle section 12 to deflect at an angle relative to the connecting part 11, ultimately raising the end of the bristles 121 away from the connecting part 11, significantly reducing the depth to which they penetrate into the gaps of the carpet fibers.

[0056] When the cleaning device 100 leaves the carpet area and returns to a normal floor such as tile or wood floor, the brush part 12 needs to be released to restore normal cleaning status: the control system first sends a signal to the first drive component 24 to further weaken the magnetic attraction. Under the combined action of the slight reaction force of the brush part 12 and its own gravity, the clamp 23 rotates towards the ground to expand the clamping space 25, thereby releasing the captured brush part 12. At the same time, the drive mechanism of the cleaning device 100 drives the brush part 1 to rotate in the opposite direction, and uses the power of the reverse rotation to push the brush part 12 to move smoothly out of the clamping space 25 defined by the clamp 23 and the body 101.

[0057] After the bristle section 12 is completely removed, the control system sends a signal to the first drive component 24, and the magnetic attraction force generated by the electromagnet returns to its initial strength, re-attaching the clamp 23 to the bottom of the body 101, returning it to its initial position of being in contact with the bottom of the body 101. Meanwhile, the bristle section 12 returns to its natural drooping state under its own gravity, with the ends of the bristles 121 once again adhering to the ground, continuing to efficiently clean ordinary floors, preparing for the next scene change (such as encountering a carpet again).

[0058] In some embodiments of this application, the first driving member 24 is configured as an electromagnet, creating a magnetic attraction between the first driving member 24 and the clamping plate 23. When the cleaning device 100 is on a normal surface, the magnetic attraction can stably fix the position of the clamping plate 23, preventing displacement of the clamping plate 23 due to vibration. Furthermore, by precisely adjusting the power supply to control the magnitude of the magnetic attraction, the rotation angle and speed of the clamping plate 23 can be flexibly controlled, causing the bristles 121 to be slightly raised, achieving a height increase for the bristles 121. Simultaneously, the design without a mechanical transmission structure reduces frictional loss between components, effectively extending the service life of the raising mechanism and reducing the maintenance cost of the cleaning device 100.

[0059] It should be further explained that in some of the above embodiments, the first driving member 24 is configured as an electromagnet, and the first driving member 24 and the clamping plate 23 generate a magnetic attraction to drive the clamping plate 23 to move. However, this application is not limited to this. For example, in some other embodiments of this application, the first driving member 24 is configured as a drive motor, and the first driving member 24 is connected to the clamping plate 23 in a transmission connection so that the first driving member 24 directly drives the clamping plate 23 to rotate. For example, the middle of the clamping plate is fixed, and the two ends of the clamping plate are free ends that can move closer to or away from the machine body, such as a seesaw structure. When one end of the clamping plate is moved by the drive motor in the direction of approaching or moving away from the machine body, the other end of the clamping plate will move away from or closer to the machine body, realizing that one end of the clamping plate rotates away from the machine body. A clamping space suitable for capturing the bristles is formed between the clamping plate and the bottom surface of the machine body. When the first driving member drives the clamping plate to rotate toward one side of the machine body, the clamping plate drives the bristles to move toward the side where the machine body is located, thereby raising the bristles.

[0060] In some embodiments of this application, the lifting mechanism includes a second driving member and at least one support plate. The second driving member is fixedly disposed on the connecting part 11 of the brush member 1 (rotating synchronously with the connecting part 11). The support plate is connected to the second driving member in a transmission manner (e.g., through a rotating shaft linkage). In the height direction of the cleaning device 100, the support plate is always located below the bristle part 12. The upward swing of the support plate directly applies an upward supporting force to the bristle part 12, pushing the bristles 121 to move relative to the connecting part 11, thereby raising the end of the bristles 121.

[0061] Specifically, when the cleaning device 100 is cleaning ordinary floors (such as tile floors or wooden floors), the second drive unit is not activated, and the tray remains in its initial downward swing position, allowing the bristles 121 to hang naturally under their own weight, with the ends of the bristles 121 tightly pressed against the ground. The drive mechanism of the cleaning device 100 drives the connecting part 11 to rotate, and the connecting part 11 simultaneously drives the second drive unit, the tray, and the bristle part 12 to rotate. The rotating bristles 121 can efficiently sweep dust and debris from the ground towards the device's suction port, ensuring the cleaning effect on ordinary floors. At the same time, the low position of the tray does not interfere with the normal hanging and cleaning action of the bristles 121.

[0062] When the cleaning equipment 100 detects a carpet in front, the control system sends a signal to the second drive unit to drive the tray to swing upward around the transmission connection point. The upward-swinging tray contacts the bottom of the bristle section 12 and applies an upward supporting force to the bristle section 12. As the tray continues to swing upward, the supporting force gradually increases, pushing the bristle section 12 to deflect upward relative to the connecting part 11 (from a natural drooping state to an "end-curved" state). Ultimately, the ends of the bristles 121 away from the connecting part 11 are raised upward, significantly reducing the depth to which the bristles 121 penetrate into the gaps in the carpet fibers. This avoids the bristles 121 getting tangled in the carpet fibers, causing equipment jamming and path deviation, while also reducing the friction intensity between the bristles 121 and the carpet, thus delaying the wear of the bristles 121.

[0063] When the cleaning device 100 leaves the carpet area and returns to a regular floor such as tile or wood flooring, and the brush bristles 121 need to return to their natural drooping state, the control system sends a reset signal to the second drive unit. The second drive unit drives the support plate to swing downwards, gradually disengaging from the brush bristles 121, and the support plate returns to its initial low position. The brush bristles 121, having lost the support of the support plate, return to their natural drooping state under their own gravity, and the ends of the bristles 121 once again press against the ground, continuing to efficiently clean the regular floor as the connecting part 11 rotates.

[0064] By designing the lifting mechanism as a second drive component and support plate, the lifting mechanism drives the brush bristle section 12 more directly. The support plate applies force directly from below the brush bristle section 12, resulting in a shorter force transmission path and more sensitive lifting action of the brush bristles 121. The lifting mechanism is integrated into the connecting part 11 of the brush component 1 and rotates synchronously with the brush component 1. This eliminates the need for additional installation space in the machine body 101, reducing the impact on the internal layout of the cleaning equipment 100. It also avoids rotational interference with the components of the machine body 101, improving overall structural stability and extending the equipment's service life.

[0065] In some embodiments of this application, the lifting mechanism includes a third drive member and at least one gripper. The third drive member is disposed on the body 101 of the cleaning device 100. The third drive member drives the gripper to grasp the bristle portion 12, causing the bristles 121 to move relative to the connecting portion 11 toward the body 101.

[0066] Specifically, when the cleaning device 100 is cleaning ordinary floors (such as tile floors or wooden floors), the third drive component is not activated, and the grippers remain in their initial open position. The bristles 121 hang naturally under their own weight, with the ends of the bristles 121 tightly pressed against the ground. The drive mechanism of the cleaning device 100 drives the connecting part 11 of the brush component 1 to rotate, and the connecting part 11 synchronously drives the bristle part 12 to rotate. The rotating bristles 121 can efficiently sweep the dust and debris on the ground towards the device's suction port, ensuring the cleaning effect of ordinary floors. At the same time, the open grippers will not interfere with the normal rotation and cleaning action of the bristles 121.

[0067] When the cleaning equipment 100 detects a carpet in front, the control system sends a signal to the third drive unit. The third drive unit first drives the gripper to move towards the bristle part 12 (at this time, the brush part 1 can be stationary so that the gripper can grab the bristle part 12). After the gripper has finished grabbing the bristle part 12, the third drive unit drives the gripper to move towards the machine body 101 (such as lifting upwards). The gripper drives the bristle part 12 to deflect towards the machine body 101 in sync through the clamping force, so that the bristle part 12 changes angle relative to the connecting part 11. Finally, the end of the bristle 121 away from the connecting part 11 rises upwards, avoiding the equipment jamming and path deviation caused by the bristle 121 being entangled by carpet fibers. At the same time, it reduces the friction intensity between the bristle 121 and the carpet and slows down the wear of the bristle 121.

[0068] When the cleaning device 100 leaves the carpet area and returns to ordinary floors such as tile or wood flooring, the grippers open, completely releasing the brush head 12. Freed from the gripper's constraint, the brush head 12 returns to its natural drooping state under its own weight, with the bristle tips once again adhering to the floor. As the connecting part 11 rotates, it continues to efficiently clean ordinary floors.

[0069] See Figure 2 As shown, in some embodiments of this application, the cleaning assembly further includes a position monitoring assembly, which includes a monitor 31 and an identification element 32. The monitor 31 is disposed on the body 101 of the cleaning device 100, and the identification element 32 is disposed on the brush 1 (which can be fixed to the circumferential edge of the connecting portion 11 of the brush 1, or the non-cleaning area of ​​the bristle portion 12). The monitor 31 accurately identifies the relative position of the brush 1 and the body 101 by monitoring the position signal of the identification element 32 in real time. For example, the monitor 31 is configured as a Hall sensor, and the identification element 32 is configured as a magnet. The two achieve position monitoring through magnetic signal interaction, which has a fast response speed and strong anti-interference ability.

[0070] For example, when the cleaning device 100 detects a carpet in front, it needs to activate the lifting module (the lifting mechanism includes a first magnetic suction element 21 and a second magnetic suction element 22). The control system first obtains the real-time position of the identification element 32 through the monitor 31 and determines whether each second magnetic suction element 22 has rotated to be directly below the corresponding first magnetic suction element 21. When the second magnetic suction element 22 reaches below the target first magnetic suction element 21, it immediately sends a "alignment complete" signal to the control system. The control system then precisely controls the first magnetic suction element 21 to be energized. After being energized, the first magnetic suction element 21 and the corresponding second magnetic suction element 22 instantly generate a magnetic attraction. Under the pull of the magnetic attraction, the bristles 121 deflect towards the first magnetic suction element 21 (body 101), and the ends of the bristles 121 away from the connecting part 11 are raised.

[0071] In some embodiments of this application, the bristles 121 are made of flexible materials, such as flexible plastics, elastic fibers, soft rubber, etc., which are deformable and wear-resistant. This not only retains the ability of the brush 1 to gather and sweep dust and debris on the ground, but also adapts to different ground flatness and the movement requirements of the lifting mechanism through the flexible properties of the material, further improving the adaptability and service life of the cleaning component.

[0072] In some embodiments of this application, the bristles 121 of the brush component 1 adopt a segmented structure, specifically including a solid segment and a movable segment: one end of the solid segment is fixedly connected to the connecting part 11 of the brush component 1, and is made of a hard material (such as hard plastic or metal core wrapped plastic) to maintain the overall structural stability of the bristles 121 and prevent the bristles 121 from breaking at the root due to long-term rotation or stress; the movable segment is connected to the other end of the solid segment through a rotatable structure such as a pivot or hinge, and can be made of a flexible material (such as soft fiber) or a lightweight hard material (such as a thin plastic sheet), and can rotate freely around the end of the solid segment, with the rotation angle range adapting to the action requirements of the lifting mechanism. Since the solid segment provides rigid support, the movable segment will not swing excessively due to centrifugal force, ensuring stable cleaning. If small bumps are encountered on the ground, the movable segment can rotate slightly around the solid segment to avoid rigid collision with the bumps, balancing cleaning stability and ground adaptability.

[0073] See Figure 2 As shown, in some embodiments of this application, the bristle section 12 further includes at least one connector 122. The core function of the connector 122 is to connect at least two bristles 121 into a single structure. When the lifting mechanism applies a lifting force to one of the bristles 121, the force can be applied to the other connected bristles 121 through the connector 122, achieving the effect of "driving one and linking multiple bristles". This ensures that multiple bristles 121 are raised synchronously, avoiding deviations in the lifting angle caused by uneven force on a single bristle 121, and adapting to the obstacle avoidance requirements of the bristle section 12 in carpet scenarios. After the lifting force disappears, under the influence of its own weight and the connection of the connector 122, all the bristles 121 connected by the same connector 122 hang down synchronously and naturally, ultimately ensuring that multiple bristles 121 hang down synchronously.

[0074] In some embodiments of this application, the bristles 121 and the connector 122 in the bristle section 12 are manufactured using an integral molding process (such as injection molding, extrusion molding, or compression molding). That is, the bristles 121 and the connector 122 are a single structure made of the same material (such as flexible nylon, soft polyester fiber, or elastic rubber), without any additional assembly interfaces. This ensures more stable force transmission through the connector 122, allowing the bristle section 12 to balance overall synchronization with local flexibility.

[0075] The cleaning device 100 according to this application is equipped with a cleaning component according to this application. As the lifting mechanism drives the tip of the bristles 121 to rise, the depth of the bristles 121 penetrating into the carpet pile is greatly reduced. This not only avoids the cleaning device 100 from getting stuck or deviating from its movement path on the carpet, but also significantly reduces the contact area and friction intensity between the bristles 121 and the carpet pile, effectively slowing down the wear rate of the bristles 121 and greatly extending the service life of the brush 1.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

Therefore, the protection scope of this patent application should be determined by the appended claims.
