Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a side brush, cleaning equipment and cleaning system. Background Technology

[0002] With the development of technology and the improvement of people's living standards, cleaning equipment is being used more and more widely in daily life, and its types and functions are constantly being enriched and improved. Common cleaning equipment on the market includes robotic vacuum cleaners, handheld floor scrubbers, etc. These devices bring great convenience to people's lives with their automated and efficient cleaning methods.

[0003] In cleaning devices such as robotic vacuum cleaners, the side brush is a key component for cleaning edge areas. To improve cleaning performance, especially in corners, edges, or narrow areas, robotic vacuum cleaners typically have side brushes with rotatable, extendable brush strips, providing an outward expansion function. When the robotic vacuum cleaner performs a regular cleaning task, the side brush rotates normally to clean the floor, and the extended brush strips are in the retracted position. However, when the robotic vacuum cleaner encounters corners, edges, or narrow areas, it controls the side brush to reverse, causing the extended brush strips to rotate and extend under centrifugal force, increasing the cleaning range and bringing the extended brush strips closer to the edge for precise edge cleaning.

[0004] However, when the extended brush strip is not in its extended working state, that is, when it should be in the retracted position, it is easily affected by external factors, such as slight collisions with debris on the ground or vibrations from the robot's movement, causing it to accidentally disengage from its retracted position. This means that during the robot's movement, the extended brush strip may be pressed down by the wheels, resulting in the side brush getting stuck. Once this happens, the robot will report an anomaly, severely affecting its normal operation, not only reducing cleaning efficiency but also potentially damaging the device itself. Utility Model Content

Furthermore, it reduces the risk of equipment damage due to side brush malfunctions, extends service life, and reduces usage and maintenance costs. Attached Figure Description

[0051] Reference Figure 1 and Figure 2 This utility model embodiment proposes a side brush 100, which is installed on a cleaning device. When the cleaning device cleans the surface to be cleaned, the side brush 100 rotates to sweep away debris on the surface. Specifically, the cleaning device may include a body 200, which is the main frame of the cleaning device and carries the core functional components of the device. An suction port may be provided at its bottom. The suction port is connected to a dust collection system inside the body 200, which may include components such as a fan and a dust box. When the cleaning device is running, the side brush 100 sweeps away dust and debris on the ground and pushes it to the suction port. At the same time, the fan operates to create negative pressure, sucking the dust and debris into the dust box through the suction port, thus achieving the cleaning operation.

[0052] Reference Figures 3 to 5 The side brush 100 includes:

[0053] The side brush holder 110 is rotatable about the first axis Z1;

[0054] The first brush bar 120 is connected to the side brush holder 110 at one end, and the first brush bar 120 can rotate around the second axis Z2 to move between the retracted position and the outward position. The second axis Z2 is spaced apart from the first axis Z1.

[0055] A locking structure 10 is provided between the side brush holder 110 and the first brush bar 120. The locking structure 10 locks the first brush bar 120 when it is in the retracted position.

[0056] The side brush 100 proposed in this embodiment mainly consists of a side brush base 110, a first brush strip 120, and a locking structure 10. The side brush base 110 can rotate around a first axis Z1 and is the basic component for the side brush 100 to achieve overall rotational cleaning. One end of the first brush strip 120 is connected to the side brush base 110 and can rotate around a second axis Z2, thereby being able to move flexibly between the retracted position and the outward position. The second axis Z2 is spaced apart from the first axis Z1, and the distance between them is set according to actual needs and is not limited. A locking structure 10 is provided between the side brush base 110 and the first brush strip 120. When the first brush strip 120 is in the retracted position, the locking structure 10 locks the first brush strip 120 to prevent it from accidentally disengaging from the position due to external interference.

[0057] Specifically, the side brush holder 110 serves as the basic support component of the side brush 100, and its structural design ensures stable rotation around the first axis Z1. The side brush holder 110 is typically connected to the drive mechanism of the cleaning equipment, which drives the side brush holder 110 to rotate around the first axis Z1 via a transmission device. The side brush holder 110 is equipped with a mounting structure for connecting the first brush strip 120. This mounting structure ensures that the first brush strip 120 can rotate around the second axis Z2, and also provides mounting space for the locking structure 10. For example, the side brush holder 110 may be provided with structures such as shaft holes for mounting and connecting the rotating shaft of the first brush strip 120, allowing the first brush strip 120 to rotate around the second axis Z2 with this rotating shaft as its center.

[0058] The first brush strip 120 is a key component for realizing the cleaning function of the side brush 100. One end of it is connected to the side brush base 110 through a connecting component such as a rotating shaft, and the other end is used to sweep the floor.

[0059] In some embodiments, the first brush strip 120 may have a certain degree of flexibility and wear resistance in its structural design to adapt to the cleaning needs of different floor environments. Meanwhile, to cooperate with the locking structure 10, the first brush strip 120 may be provided with corresponding locking structures, such as slots or holes. When the first brush strip 120 is in the retracted position, the locking structure 10 can interact with these locking structures to lock the first brush strip 120.

[0060] The locking structure 10 reliably locks the first brush bar 120 when it is in the retracted position. The locking structure 10 can take various forms, such as a mechanical snap-locking structure 10, which consists of a snap-lock on the side brush holder 110 and a slot / hole on the first brush bar 120. When the first brush bar 120 rotates to the retracted position, the snap-lock accurately engages with the slot / hole, thereby restricting the rotation of the first brush bar 120 and achieving the locking function. To ensure the reliability of the lock, the shape and size of the snap-lock and the slot / hole must match, and the snap-lock should have a certain degree of elasticity to ensure that it does not easily disengage from the slot when subjected to slight vibrations or other external disturbances.

[0061] Taking the use of an elastic plunger (i.e., a positioning bead) in the buckle as an example, the first brush strip 120 is provided with a corresponding positioning hole. When the cleaning equipment is started and performs a regular cleaning task, it continues to move along the predetermined cleaning path. The side brush holder 110 rotates clockwise around the first axis Z1 under the drive of the drive mechanism. Figure 1 As shown, at this time, the first brush bar 120 is in the retracted position, and the cleaning range (i.e., Figure 1 The circular cleaning area shown is small, and the elastic plunger extends from the side brush holder 110 to engage with the positioning hole to lock the first brush strip 120. In the locked state, even if the cleaning device encounters debris or vibrations during movement, the first brush strip 120 will not disengage from the retracted position.

[0062] When the cleaning equipment detects the need for cleaning corner areas, such as wall corners, edges, or narrow areas, it temporarily stops on the cleaning path. It then controls the side brush holder 110 to rotate in reverse around the first axis Z1. Upon reaching a preset speed, centrifugal force causes the elastic plunger to disengage from the positioning hole and retract into the side brush holder 110, thereby unlocking the first brush strip 120. Figure 2 As shown, in the unlocked state, the first brush bar 120 rotates from the retracted position to the expanded position, increasing the cleaning range (i.e., Figure 2 The circular cleaning range shown in the figure is increased to achieve precise edge cleaning.

[0063] After cleaning the edge area, the side brush holder 110 is rotated forward again. The first brush bar 120 gradually returns to the retracted position under its own gravity and rotational inertia. The elastic plunger on the side brush holder 110 then re-engages with the positioning hole, automatically locking the first brush bar 120 and restoring the side brush 100 to the normal cleaning state. Then the cleaning equipment continues to move along the cleaning path.

[0064] The locking structure 10 in the above example can automatically unlock and lock the first brush strip 120 by controlling the rotation direction of the switching side brush 100. In addition, the locking structure 10 can also be equipped with an unlocking mechanism. When the first brush strip 120 needs to be expanded outwards, the unlocking mechanism is controlled to release the locking structure 10 from the first brush strip 120, allowing the first brush strip 120 to rotate smoothly to the expanded position under centrifugal force or other actions. The unlocking mechanism can be electric or mechanical, for example, by using a micro-motor to drive a linkage mechanism to disengage the latch from the slot. Furthermore, besides the latch and slot / hole cooperation structure shown, the locking structure 10 can also use other methods, such as a magnetic attraction structure 11, etc. This embodiment does not limit this approach.

[0065] In this embodiment, the side brush 100 has a locking structure 10 between the side brush seat 110 and the first brush strip 120. When the first brush strip 120 is in the retracted position, it is locked, which can at least effectively resist the interference of slight collisions from ground debris and equipment vibration, and reduce the risk of the first brush strip 120 accidentally disengaging from the retracted position. This reduces the risk of jamming and abnormal flow caused by the outward-expanding brush strip being pressed by the traveling wheel, ensures stable operation of the equipment, and significantly improves cleaning efficiency. At the same time, it reduces the risk of equipment damage due to side brush 100 failure, extends service life, and reduces use and maintenance costs.

[0066] The side brush 100 in this embodiment is suitable for a variety of cleaning scenarios, whether it is a home, office or commercial place, and can reliably achieve regular cleaning and edge area cleaning functions according to different cleaning needs.

[0067] In some embodiments, refer to Figure 5 The rotation direction of the side brush holder 110 includes a first direction and a second direction opposite to the first direction;

[0068] When the side brush holder 110 rotates in the first direction, the first brush bar 120 rotates to the retracted position, and the locking structure 10 locks the first brush bar 120.

[0069] When the side brush holder 110 rotates in the second direction, the first brush bar 120 can disengage from the locking structure 10 and retract from the retracted position.

[0070] In this embodiment, the rotation direction of the side brush holder 110 is divided into a first direction and a second direction, with the second direction being opposite to the first direction. For example, the first direction can be clockwise, and the second direction can be counterclockwise; or, the first direction can be counterclockwise, and the second direction can be clockwise. The rotation direction of the side brush holder 110 provides the basic logic for the side brush 100 to switch between different working states.

[0071] When the side brush holder 110 rotates in the first direction, the first brush strip 120 gradually rotates to the retracted position. At this time, the locking structure 10 between the side brush holder 110 and the first brush strip 120 functions to lock the first brush strip 120 in the retracted position. Specifically, continuing the example structure of the aforementioned embodiment, the latch in the locking structure 10 precisely engages with the slot on the first brush strip 120. The latch, with its own elasticity, engages with the slot, restricting the rotational freedom of the first brush strip 120 and keeping it stably in the retracted position. In this state, the side brush 100 is suitable for routine floor cleaning tasks, such as cleaning the floors of an open living room or bedroom. Because the first brush strip 120 is reliably locked, even if the cleaning equipment encounters ground bumps, collisions with debris, or vibrations caused by uneven ground during movement, the first brush strip 120 will not easily detach, thus ensuring that the side brush 100 can continue to work stably in the normal mode.

[0072] When the side brush holder 110 rotates in the second direction, the centrifugal force generated by the rotation acts on the first brush strip 120. Under the action of this centrifugal force, and with the help of the friction between the first brush strip 120 and the surface to be cleaned, the latch in the locking structure 10 disengages from the slot of the first brush strip 120, releasing the lock on the first brush strip 120. After the lock is released, the first brush strip 120, driven by the centrifugal force, rotates around the second axis Z2 and moves out of the retracted position, gradually extending to the outward position. At this time, the cleaning range of the side brush 100 is effectively expanded, making it particularly suitable for cleaning narrow edge areas such as corners, edges, and the bottom of furniture. For example, when the robot vacuum cleaner approaches a corner, by controlling the side brush holder 110 to rotate in the second direction, the first brush strip 120 quickly expands outward, reaching deep into the corner crevices to clean up dust, hair, and other debris, achieving precise and efficient corner cleaning.

[0073] This embodiment achieves intelligent and convenient switching between the side brush 100 and the corner cleaning mode by setting the rotation direction of the side brush holder 110. In open areas where edge cleaning is not required, the side brush 100 rotates in the first direction, and the first brush strip 120 is locked in the retracted position, ensuring efficient and stable cleaning. When encountering edge areas that need cleaning, simply changing the rotation direction of the side brush holder 110 will automatically expand the first brush strip 120, eliminating the need for complex additional operations and control logic. This simplifies the workflow of the cleaning equipment and enhances its intelligence and ease of operation.

[0074] In some embodiments, refer to Figure 4 The locking structure 10 includes a magnetic attraction structure 11, which forms a magnetic attraction force that can lock the first brush bar 120 when the first brush bar 120 is in the retracted position.

[0075] In this embodiment, the locking structure 10 adopts a magnetic attraction structure 11, which uses magnetic properties to lock the first brush strip 120. For example, the magnetic attraction structure 11 consists of a magnetic component disposed on the side brush holder 110 and a magnetic engagement component disposed on the first brush strip 120.

[0076] When the side brush holder 110 rotates in the forward direction or along the first direction, causing the first brush strip 120 to rotate to the retracted position, the magnetic components and magnetic mating components in the magnetic attraction structure 11 gradually approach each other. Based on the principle of like poles repelling and unlike poles attracting in magnetic materials, when the two approach a certain distance, a strong magnetic attraction force is formed. The sum of the magnetic attraction force and the frictional force between the first brush strip 120 and the surface to be cleaned is greater than the centrifugal force generated by rotation, thereby firmly locking the first brush strip 120 in the retracted position. This magnetic attraction force can effectively resist external interference forces such as collisions with debris on the ground and vibrations from equipment operation, ensuring that the first brush strip 120 remains stable during the execution of regular cleaning tasks and will not easily detach.

[0077] Under certain operating conditions, when the first brush strip 120 approaches the magnetic attraction component on the side brush holder 110, the magnetic attraction force generated by the magnetic component on the side brush holder 110 and the magnetically engaging component on the first brush strip 120 can assist the first brush strip 120 in moving to the retracted position. Also, as... Figure 6 As shown, when the first brush strip 120 is disengaged from the retracted position and is close to the contact point between the covered travel wheel 300 and the surface to be cleaned, there is a certain disengagement angle (such as 90°) between the first brush strip 120 and the retracted position. If the first brush strip is subjected to external interference such as collision with a foreign object or vibration during equipment operation, the effective adsorption angle between the magnetic component on the side brush holder 110 and the magnetic mating component on the first brush strip 120 is greater than the disengagement angle, so as to ensure that the travel wheel cannot press on the first brush strip 120.

[0078] When the side brush holder 110 rotates in the opposite direction or along the second direction, and the first brush strip 120 needs to expand outward, after the side brush holder 110 reaches the preset speed, the sum of the centrifugal force generated by the rotation and the frictional force between the first brush strip 120 and the surface to be cleaned is greater than the magnetic attraction force, thereby disengaging the first brush strip 120 from the locking of the magnetic attraction structure 11, rotating and extending to the outward expansion position to meet the cleaning needs of edge areas such as corners and edges of walls.

[0079] In this embodiment, the components of the magnetic suction structure 11 are relatively simple, mainly consisting of magnetic components and magnetic mating components. It does not require complex mechanical transmission mechanisms and precise coordination of multiple parts, making the overall structure of the side brush 100 more concise and compact. Furthermore, the magnetic suction structure 11 has low requirements for the working environment and can stably perform the locking function in both dry indoor environments and high humidity environments.

[0080] In some embodiments, the locking structure 10 includes a retaining structure that forms a retaining force capable of locking the first brush bar 120 when the first brush bar 120 is in the retracted position.

[0081] In this embodiment, the locking structure 10 adopts a latching structure, which utilizes the latching force characteristic to lock the first brush strip 120. For example, the latching structure consists of a latching member disposed on the side brush holder 110 and a latching mating part disposed on the first brush strip 120. The latching member can be a structure with elastic buckle, hook, etc., and the latching mating part is correspondingly configured as a slot, hole, etc. The specific working principle and scenarios can be found in the aforementioned embodiments, and will not be described in detail here. In this embodiment, the latching structure can achieve rigid locking of the first brush strip 120 through the latching force formed by mechanical engagement, and the locking effect is intuitive and reliable.

[0082] In some embodiments, refer to Figure 3 and Figure 4 The first brush bar 120 includes a first connecting arm 121 and a first bristle strip 122. One end of the first connecting arm 121 is rotatably connected to the side brush holder 110, and the other end of the first connecting arm 121 is connected to the first bristle strip 122.

[0083] In this embodiment, the first brush strip 120 adopts a split structure design, consisting of a first connecting arm 121 and a first bristle strip 122. These two components work together through a specific connection method to achieve the cleaning function of the side brush 100. One end of the first connecting arm 121 is rotatably connected to the side brush holder 110 via a rotating shaft or other rotatable connecting component. This connection method allows the first connecting arm 121 to rotate flexibly around the second axis Z2, thus freely switching between a retracted position and an extended position. For example, by providing a shaft hole on the side brush holder 110, a rotating shaft is installed at the end of the first connecting arm 121 and inserted into the shaft hole. The other end of the first connecting arm 121 is connected to the first bristle strip 122, which is used to contact the surface to be cleaned for cleaning.

[0084] During operation, when the side brush holder 110 rotates forward or along the first direction, the first connecting arm 121 drives the first bristle strip 122 to the retracted position. At this time, the locking structure 10 locks the first connecting arm 121, keeping the first bristle strip 122 stably in this position to adapt to routine floor cleaning tasks. When the side brush holder 110 rotates in the opposite direction or along the second direction, the locking structure 10 is released. Under the action of centrifugal force, the first connecting arm 121 rotates around the second axis Z2, causing the first bristle strip 122 to extend to the outward position. The first bristle strip 122, with its soft and dense bristles, penetrates into narrow areas such as corners and edges of walls to sweep away dust, hair, debris, and other impurities, achieving efficient edge cleaning.

[0085] In some embodiments, refer to Figure 7 and Figure 8 The magnetic structure 11 includes a first magnetic member 11A and a second magnetic member 11B. The first magnetic member 11A is disposed on the side brush seat 110, and the second magnetic member 11B is disposed on the first connecting arm 121. The second magnetic member 11B can be magnetically attracted to the first magnetic member 11A.

[0086] In this embodiment, the magnetic attraction structure 11 used in the locking structure 10 is composed of a first magnetic attraction component 11A and a second magnetic attraction component 11B. The two interact with each other through magnetic force to achieve reliable locking and unlocking of the first brush strip 120, thus ensuring the stable operation of the side brush 100 under different working conditions.

[0087] The first magnetic chuck 11A is disposed on the side brush holder 110, and the second magnetic chuck 11B is mounted on the first connecting arm 121. The positions and orientations of the two are precisely designed to ensure that an effective magnetic attraction force can be generated when the first brush bar 120 is in the retracted position. Both the first magnetic chuck 11A and the second magnetic chuck 11B can be permanent magnets, or one of them can be a permanent magnet while the other is a metal part that can be magnetically attracted to the permanent magnet. This embodiment does not impose any limitations on this.

[0088] During operation, when the side brush holder 110 rotates forward or in the first direction, causing the first connecting arm 121 and the first brush strip 122 to rotate to the retracted position, the first magnetic attractor 11A mounted on the side brush holder 110 and the second magnetic attractor 11B mounted on the first connecting arm 121 gradually approach each other. As the distance decreases, the magnetic attraction between the two gradually increases, which can assist the first brush strip 120 in moving to the retracted position or attract the first brush strip 120 back to the retracted position. When the first brush strip 120 reaches the accurate retracted position, the magnetic attraction reaches a strength sufficient to lock the first connecting arm 121, so that the first brush strip 120 is stably kept in the retracted state.

[0089] When the side brush holder 110 rotates in the opposite direction or along the second direction, requiring the first brush strip 120 to expand outward, after the side brush holder 110 reaches the preset speed, the centrifugal force generated by the rotation and the friction between the first brush strip 120 and the surface to be cleaned overcome the magnetic attraction, causing the first connecting arm 121 to disengage from the lock. After the magnetic lock is released, the first connecting arm 121 rotates around the second axis Z2 under the action of centrifugal force, causing the first bristle strip 122 to extend to the outward position, thereby achieving cleaning of edge areas such as corners and edges of walls.

[0090] In some embodiments, refer to Figure 7 and Figure 8 An extension arm 110W is provided on the edge of the side brush holder 110, and one end of the first connecting arm 121 is rotatably connected to the extension arm 110W.

[0091] The first magnetic absorbing element 11A is located on the extension arm 110W.

[0092] In this embodiment, the side brush holder 110 serves as the core support component of the side brush 100, with its edge extending outward to form an extension arm 110W. This extension arm 110W provides a carrier for the rotatable connection of the first connecting arm 121 and the installation of the first magnetic chuck 11A. One end of the first connecting arm 121 is no longer directly connected to the main body of the side brush holder 110, but is instead rotatably connected to the extension arm 110W through a rotatable connecting component (such as a rotating shaft). This connection method allows the first connecting arm 121 to rotate flexibly between the retracted position and the extended position around the second axis Z2 with the rotation connection point as the axis. Furthermore, due to the setting of the extended arm 110W, the interval between the second axis Z2 and the first axis Z1 can be set to be larger, which can increase the centrifugal force experienced by the first brush bar 120 when the side brush seat 110 rotates. This is beneficial for the first brush bar 120 to switch between the retracted position and the extended position. Moreover, when the first brush bar 120 is in the extended position, the cleaning area of ​​the first brush bar 120 can be further extended, and the rotation space of the first connecting arm 121 is optimized, making the rotation process smoother.

[0093] Meanwhile, the first magnetic chuck 11A is disposed on the extension arm 110W and cooperates with the second magnetic chuck 11B mounted on the first connecting arm 121. During the design process, the position and orientation of the first magnetic chuck 11A on the extension arm 110W and the corresponding position of the second magnetic chuck 11B on the first connecting arm 121 are planned. For example, the first magnetic chuck 11A is mounted on a surface of the extension arm 110W facing the first connecting arm 121, and the second magnetic chuck 11B is mounted on the corresponding surface of the first connecting arm 121. This ensures that when the first connecting arm 121 drives the first hair strip 122 to rotate to the retracted position, the first magnetic chuck 11A and the second magnetic chuck 11B can be accurately aligned and generate a sufficiently strong magnetic attraction force.

[0094] In some embodiments, refer to Figure 7 and Figure 8 The first magnetic chuck 11A is disposed adjacent to the edge of the extension arm 110W facing the retracted position; and / or,

[0095] The second magnetic chuck 11B is disposed adjacent to the side edge of the first connecting arm 121 facing the retracted position.

[0096] In this embodiment, the placement position of the magnetic element in the magnetic structure 11 may include:

[0097] Position 1: The first magnetic chuck 11A is disposed near the edge of the extension arm 110W on one side toward the retracted position;

[0098] Position 2: The second magnetic chuck 11B is disposed adjacent to the side edge of the first connecting arm 121 facing the retracted position;

[0099] Position 3: The first magnetic clasp 11A is disposed near the edge of the extension arm 110W toward the retracted position, and at the same time the second magnetic clasp 11B is disposed near the edge of the first connecting arm 121 toward the retracted position.

[0100] The above settings can be selected according to actual needs, and this embodiment does not impose any restrictions on them.

[0101] Since the first magnetic clasp 11A and / or the second magnetic clasp 11B are located close to the edge, they can generate a strong magnetic force even before the first connecting arm 121 has fully returned to the accurate retracted position, guiding the first connecting arm 121 to quickly and accurately return to the retracted position and complete the locking.

[0102] In some embodiments, refer to Figure 4 , Figure 7 and Figure 8 The extension arm 110W has a mounting cavity 110Q. One end of the first connecting arm 121 is located in the mounting cavity 110Q and is rotatably connected to the extension arm 110W via a connecting shaft 20.

[0103] In this embodiment, the structure of the extension arm 110W is optimized. A mounting cavity 110Q is constructed to achieve a rotatable connection between the first connecting arm 121 and the extension arm 110W, improving the overall stability and reliability of the side brush 100 structure. The extension arm 110W, as an extension of the side brush holder 110, has a mounting cavity 110Q of a specific shape and size. The design of the mounting cavity 110Q fully considers the external contour and rotational requirements of the first connecting arm 121, providing precise installation space for the first connecting arm 121. One end of the first connecting arm 121 extends into the mounting cavity 110Q, and the two are rotatably connected via a connecting shaft 20. A through hole 121K is provided through the first connecting arm 121. The connecting shaft 20 can be connected to or integrally formed into the inner wall of the mounting cavity 110Q of the extension arm 110W, and passes through the through hole 121K of the first connecting arm 121, providing smooth support for the rotation of the first connecting arm 121.

[0104] In some embodiments, refer to Figure 7 and Figure 8 The side brush holder 110 includes a first housing 111 and a second housing 112 that are joined together. The edge of the first housing 111 is provided with a first extension portion 111W, and the edge of the second housing 112 is provided with a second extension portion 112W. The second extension portion 112W and the first extension portion 111W are combined to form an extension arm 110W, and a connecting shaft 20 is formed between the second extension portion 112W and the first extension portion 111W. The first connecting arm 121 is provided with a through hole, and the first connecting arm 121 is sleeved on the connecting shaft 20 through the through hole.

[0105] The first extension portion 111W or the second extension portion 112W is provided with a first mounting hole, and the first magnetic member 11A is accommodated in the first mounting hole; the first connecting arm 121 is provided with a second mounting hole, and the second magnetic member 11B is accommodated in the second mounting hole.

[0106] In this embodiment, the side brush holder 110 adopts a split structure, consisting of a first housing 111 and a second housing 112 that are joined together. The edges of the two housings are respectively constructed with a first extension portion 111W and a second extension portion 112W. When the first housing 111 and the second housing 112 are joined, the second extension portion 112W and the first extension portion 111W are spliced ​​together to form the extension arm 110W structure. During the assembly process, a connecting shaft 20 is formed between the second extension portion 112W and the first extension portion 111W. This connecting shaft 20 serves as the core support component for the rotation of the first connecting arm 121 and can be separately disposed on the first extension portion 111W and the second extension portion 112W. The first connecting arm 121 is provided with a through hole 121K. Through this through hole 121K, the first connecting arm 121 can be sleeved onto the connecting shaft 20, thereby achieving a rotatable connection with the extension arm 110W. This connection method allows the first connecting arm 121 to rotate flexibly between the retracted position and the extended position around the second axis Z2, with the connecting shaft 20 as the center. During the rotation of the first connecting arm 121, the fit between the connecting shaft 20 and the through hole, as well as the overall structure of the extended arm 110W, provide stable and smooth rotational support for the first connecting arm 121, ensuring the reliability of its rotation process.

[0107] For the magnetic attraction structure 11, a first mounting hole is provided in the first outer extension 111W or the second outer extension 112W. The first magnetic attraction component 11A can be precisely accommodated in the first mounting hole. By using snap-fit, adhesive bonding, or other fixing methods, the first magnetic attraction component 11A is ensured to be firmly installed on the outer extension arm 110W. At the same time, a second mounting hole is provided on the first connecting arm 121. The second magnetic attraction component 11B is accommodated in the second mounting hole, and a suitable fixing method is also used to ensure its firm installation. By installing the first magnetic attraction component 11A and the second magnetic attraction component 11B in the first mounting hole and the second mounting hole respectively, the relative position and spacing between the two can be precisely controlled, thereby optimizing the magnitude and direction of the magnetic attraction force. This ensures that when the first connecting arm 121 is in the retracted position, the magnetic attraction force can act on the first connecting arm 121 evenly and stably, improving the reliability of locking.

[0108] In some embodiments, refer to Figure 7 The extension arm 110W is provided with a first limiting part 1X. When the first brush bar 120 is in the retracted position, the first connecting arm 121 abuts against the first limiting part 1X; and / or,

[0109] The extension arm 110W is provided with a second limiting part 2X. When the first brush bar 120 is in the outward expansion position, the first connecting arm 121 abuts against the second limiting part 2X.

[0110] In this embodiment, a limiting structure is provided on the extension arm 110W, and the limiting structure may be configured in the following ways:

[0111] In form one, the extension arm 110W is provided with a first limiting part 1X, which is used to abut against the first brush bar 120 when it is in the retracted position.

[0112] Form 2: The extension arm 110W is provided with a second limiting part 2X, which is used to abut against the first brush bar 120 when it is in the outward expansion position;

[0113] Form 3: The extension arm 110W is provided with a first limiting part 1X, which is used to abut against the first brush bar 120 when it is in the retracted position, and at the same time, the extension arm 110W is provided with a second limiting part 2X, which is used to abut against the first brush bar 120 when it is in the outward expansion position.

[0114] The above settings can be selected according to actual needs, and this embodiment does not impose any restrictions on them.

[0115] Specifically, when the first brush bar 120 is in the retracted position, the first connecting arm 121 will accurately abut against the first limiting part 1X during rotation. The shape, position, and size of the first limiting part 1X can be adapted to the side structure of the first connecting arm 121, providing stable support and limiting for the first connecting arm 121. This abutting position and engagement method, combined with the locking effect of the magnetic attraction structure 11, provides double protection to ensure that the first connecting arm 121 is firmly held in the retracted position.

[0116] When the side brush holder 110 rotates in the second direction, the first connecting arm 121, under the action of centrifugal force, drives the first bristle strip 122 to rotate to the outward expansion position. At this point, the first connecting arm 121 will abut against the second limiting part 2X. The second limiting part 2X is also designed according to the movement trajectory and position requirements of the first connecting arm 121 when it expands outward, and can precisely limit the rotation angle and position of the first connecting arm 121 to prevent it from rotating excessively. In this way, when the first brush strip 120 is cleaning the edge area, the second limiting part 2X ensures that the first bristle strip 122 is always in the best cleaning position, giving full play to its cleaning efficiency and cleaning corners, edges and other areas efficiently. Furthermore, through the limiting effect of the second limiting part 2X, the first connecting arm 121 is prevented from colliding or interfering with other components due to excessive rotation, thus protecting the structural integrity of each component of the side brush 100.

[0117] In some embodiments, refer to Figure 5 When the first brush bar 120 is in the retracted position, the radial distance from its end to the first axis Z1 is the first distance value L1; when the first brush bar 120 is in the outward expansion position, the radial distance from its end to the first axis Z1 is the second distance value L2; wherein, the second distance value L2 is greater than the first distance value L1.

[0118] In this embodiment, the positional characteristics of the first brush strip 120 under different working states are clearly defined. By setting different values ​​of the radial distance from the end of the first brush strip 120 to the first axis Z1 in the retracted position and the outward expansion position, the side brush 100 cleaning function can be flexibly switched and efficiently operated.

[0119] When the first brush strip 120 is in the retracted position, the radial distance from its end to the first axis Z1 is defined as the first distance value L1. At this time, the side brush holder 110 can rotate along the first direction, and the first brush strip 120 is stably maintained in a position relatively close to the center of the side brush holder 110 under the action of the locking structure 10 (such as the magnetic suction structure 11), and is in the retracted state. In this state, the cleaning range of the first brush strip 120 is relatively small.

[0120] When the first brush strip 120 is in the outward-expanding position, the radial distance from its end to the first axis Z1 is defined as the second distance value L2, and the second distance value L2 is greater than the first distance value L1. At this time, the side brush holder 110 can rotate along the second direction, and the first brush strip 120, under the action of centrifugal force, is stably maintained in a position relatively far from the center of the side brush holder 110, in the outward-expanding state. In this state, the cleaning range of the first brush strip 120 is relatively large.

[0121] In some embodiments, refer to Figure 5 The Side Brush 100 also includes:

[0122] The second brush bar 130 is connected at one end to the side brush holder 110;

[0123] Among them, the radial distance from the end of the second brush bar 130 to the first axis Z1 is the third distance value L3, which is less than the second distance value L2.

[0124] In this embodiment, the side brush 100 adds a second brush bar 130 to the original first brush bar 120. By designing the radial distance between the second brush bar 130 and the first axis Z1, and cooperating with the first brush bar 120, the cleaning function of the side brush 100 is upgraded.

[0125] The side brush holder 110, as the core load-bearing component, is connected not only to the first brush strip 120 but also to the second brush strip 130. One end of the second brush strip 130 is securely connected to the side brush holder 110, and the radial distance from its end to the first axis Z1 is set to a third distance value L3, which is less than the second distance value L2 (i.e., the radial distance from the end of the first brush strip 120 to the first axis Z1 when the first brush strip 120 is in the outward-expanding position). This distance setting allows the second brush strip 130 to form a differentiated cleaning coverage area from the first brush strip 120 during the operation of the side brush 100.

[0126] During operation, when the side brush holder 110 rotates in the first direction to perform a routine cleaning task, the first brush strip 120 is in the retracted position and remains stable under the action of the locking structure 10. At this time, the second brush strip 130 works together with the first brush strip 120. The second brush strip 130, with its relatively short radial spacing, can clean the ground within a certain range around the side brush holder 110.

[0127] When the side brush holder 110 rotates in the second direction, and the first brush strip 120 switches to the outward expansion position, its end extends to a larger radial distance, reaching into narrow areas such as corners and edges for cleaning. At this time, the second brush strip 130 maintains its relatively fixed cleaning range, complementing the expanded first brush strip 120. The second brush strip 130 continues to clean the area around the side brush holder 110, while the first brush strip 120 focuses on deep cleaning of the edge areas. Together, they achieve comprehensive cleaning of different areas and different types of floor debris, significantly improving the overall cleaning ability of the side brush 100.

[0128] This utility model also proposes a cleaning device, referring to... Figure 1 and Figure 2 The cleaning equipment includes:

[0129] The body is 200mm long, and the bottom of the body has an intake port;

[0130] The side brush 100, as described in the foregoing embodiment, is mounted on the body 200 and located next to the suction port.

[0131] The specific structure of the side brush 100 is as described in the above embodiments. Since this cleaning device employs all the technical solutions of all the above embodiments, it possesses at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be elaborated upon further here. The cleaning device involved in this embodiment can be a robotic vacuum cleaner, including but not limited to this. In this embodiment, the body 200 serves as the main frame of the cleaning device, bearing the core functional components of the device, and has a suction port at its bottom. The suction port is connected to the dust collection system inside the body 200, which typically includes components such as a fan and a dust box.

[0132] When the cleaning equipment is running, the side brush 100 sweeps up dust and debris on the ground and pushes them to the suction inlet. At the same time, the fan works to create negative pressure, which sucks the dust and debris into the dust box through the suction inlet, thus completing the cleaning operation.

[0133] In some embodiments, the side brush 100 is the side brush 100 as described in the foregoing embodiments, referring to... Figure 1 and Figure 2 The cleaning equipment also includes:

[0134] The walking wheel 300 is set at the bottom of the body 200 and is used to walk on the surface to be cleaned. The radial distance from the contact point between the walking wheel 300 and the surface to be cleaned to the first axis Z1 is the fourth distance value. The fourth distance value is greater than the first distance value L1 and less than the second distance value L2.

[0135] In this embodiment, the walking wheel 300 is disposed at the bottom of the body 200 for walking on the surface to be cleaned. The radial distance from the contact point between the walking wheel 300 and the surface to be cleaned to the first axis Z1 is set as a fourth distance value. This fourth distance value is greater than the radial distance from the end of the first brush bar 120 to the first axis Z1 when it is in the retracted position (first distance value L1). When the cleaning equipment performs a regular cleaning task, the walking wheel 300 continues to walk on the surface to be cleaned, and the side brush 100 rotates to clean. This distance setting ensures that the first brush bar 120 in the retracted position will not come into contact with or interfere with the walking wheel 300 during rotation, and will not be pressed down by the walking wheel 300, thus ensuring that the side brush 100 can rotate and clean normally in the regular cleaning mode.

[0136] When the first brush strip 120 is in the outward expansion position, the fourth spacing value is less than the radial distance from the end of the first brush strip 120 to the first axis Z1 when it is in the outward expansion position (the second spacing value L2). When the cleaning device performs the corner cleaning task, the walking wheel 300 is stationary on the surface to be cleaned, and the side brush 100 rotates to clean. This spacing setting allows the first brush strip 120 in the outward expansion position to contact and pass over the walking wheel 300 during rotation, so as to achieve cleaning in the corner cleaning mode.

[0137] This utility model also proposes a cleaning system, which includes:

[0138] Clean base stations; and

[0139] As described in the foregoing embodiments, the cleaning equipment is used in conjunction with a cleaning base station, and the cleaning equipment performs maintenance within the base station.

[0140] The specific structure of the cleaning equipment is as described in the above embodiments. Since this cleaning system adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0141] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
