Description

Technical Field

[0001] This application relates to the technical field of cleaning modules, and more particularly to a cleaning module and cleaning equipment. Background Technology

[0002] Cleaning equipment, also known as automatic cleaning machines, smart vacuum cleaners, or robotic vacuum cleaners, is a type of smart home appliance that uses artificial intelligence to automatically clean floors in a room. It typically uses brushing and vacuuming methods to suck up debris into its own dustbin, thus completing the cleaning function. Generally speaking, robots that perform sweeping, vacuuming, and mopping are also categorized as cleaning equipment.

[0003] Currently, in order to increase the cleaning range, especially for hard-to-clean areas such as corners, cleaning equipment designs the cleaning components as movable structures, allowing the cleaning components to extend relative to the main unit, making it easier for the cleaning components to effectively clean hard-to-clean areas. However, the movable structures used in existing cleaning equipment are relatively complex and occupy too much installation space of the main unit. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning module and cleaning equipment that achieves stable position movement of the cleaning components with a simple structure, so that the cleaning area of ​​the cleaning components covers corners and other hard-to-clean corners, improves the corner cleaning coverage, and does not occupy too much space in the main body of the equipment.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On the one hand, a cleaning module is provided, including: a base, a swing arm, a drive assembly, a first transmission assembly, and a cleaning assembly;

[0007] The swing arm is rotatably connected to the base, the drive assembly is installed at one end of the swing arm, the cleaning assembly is installed at the other end of the swing arm, and the output end of the drive shaft of the drive assembly is connected to the cleaning assembly and can drive the cleaning assembly to rotate.

[0008] The swing arm is provided with a limiting component. The first transmission component is connected to the output end of the drive shaft. The first transmission component can rotate around the drive shaft under the drive of the drive component. During the rotation of the first transmission component, it can contact the limiting component, causing the swing arm to swing relative to the base, thereby causing the cleaning component to move between the first cleaning position and the second cleaning position.

[0009] Furthermore, the first transmission component includes a swing member, a rotating shaft, and a friction member. One end of the swing member is connected to the drive shaft, and the other end is connected to the rotating shaft. The friction member is rotatably connected to the rotating shaft and connected to the output end of the drive shaft. The inner wall surface of the base is provided with a corrugated surface that cooperates with the friction member for transmission.

[0010] Furthermore, the output end of the drive shaft is provided with a drive gear, and the friction element includes a first gear and a friction wheel. Both the first gear and the friction wheel are connected to the rotating shaft. The first gear meshes with the drive gear and can drive the friction wheel to rotate in the same direction. The outer wall surface of the friction wheel meshes with the corrugated surface for transmission.

[0011] Furthermore, the first transmission assembly also includes a connector, which is disposed between the first gear and the friction wheel, or between the rotating shaft and the friction wheel, so that the first gear and the friction wheel can rotate at the same speed or at different speeds.

[0012] Furthermore, the connecting member is an elastic member, which is disposed between the rotating shaft and the friction wheel. The elastic member causes the friction wheel to always have a tendency to move in the direction of the first gear, so as to increase the damping friction between the friction wheel and the first gear.

[0013] Furthermore, the first transmission component is configured such that: the first transmission component rotates relative to the drive shaft in a first clockwise direction under the drive of the drive gear; during the rotation of the first transmission component, the friction wheel contacts the corrugated surface, causing the first gear and the friction wheel to rotate in a second clockwise direction, thereby driving the swing member to rotate in the second clockwise direction; during the rotation of the swing member, the swing member contacts the limiting member, thereby driving the swing arm to swing in the first clockwise direction.

[0014] Furthermore, the first transmission assembly also includes a damping element disposed between the rotating shaft and the first gear, which is used to increase the damping friction between the rotating shaft and the first gear. When the friction wheel separates from the corrugated surface, the drive shaft can drive the first transmission assembly to rotate in the same clockwise direction through the drive gear.

[0015] Furthermore, the cleaning component is configured such that, during the contact transmission between the friction wheel and the corrugated surface, the cleaning component switches between the first cleaning position and the second cleaning position; or during the process of the friction wheel and the corrugated surface moving from contact to separation, the cleaning component switches between the first cleaning position and the second cleaning position.

[0016] Furthermore, the limiting member includes an arc-shaped limiting strip protruding into the swing arm and / or the inner wall surface of the swing arm.

[0017] Furthermore, it also includes a second transmission component, the input end of which is connected to the output end of the drive shaft, and the output end of which is connected to the cleaning component. The second transmission component is configured such that when the drive shaft rotates in a first clockwise direction or a second clockwise direction, the cleaning component can be driven to rotate in a set direction by the transmission of the second transmission component.

[0018] Furthermore, the second transmission assembly includes a second gear, a third gear, a fourth gear, a fifth gear, and a transmission gear set. The second gear meshes with the drive gear, the third gear is coaxially arranged with the second gear, the fourth gear meshes with the second gear, and the fifth gear is coaxially arranged with the fourth gear. The input end of the transmission gear set meshes with either the third gear or the fifth gear, and the output end is connected to the cleaning assembly. The second gear can selectively drive the third gear to rotate in the same direction, or mesh with the fourth gear and then drive the fifth gear to rotate in the opposite direction.

[0019] Furthermore, the cleaning component is a dry cleaning component or a wet cleaning component; wherein, the dry cleaning component includes a side sweeper.

[0020] On the other hand, a cleaning device is also provided, characterized in that it includes the cleaning module as described above.

[0021] The beneficial effects of this application are as follows: The cleaning module of this application innovatively adopts a simple and efficient mechanical structure to significantly improve the coverage and efficiency of corner cleaning. The device mainly consists of a base, a swing arm, a drive assembly, a first transmission assembly, and a cleaning assembly. The swing arm is rotatably connected to the base, with the drive assembly installed at one end and the cleaning assembly on the other. When the drive assembly is activated, the drive shaft rotates accordingly, directly driving the cleaning assembly to perform a rotational cleaning action, and also realizing the swing of the swing arm through the first transmission assembly. The first transmission assembly is closely matched with the output end of the drive shaft and can rotate around the drive shaft under the rotation of the drive assembly. During this process, a specific part of the first transmission assembly will contact the limiting part set on the swing arm. As the rotation continues, this contact generates a torque that pushes the swing arm to swing around its rotation connection point, allowing the cleaning assembly to move flexibly to different positions in the room, especially areas such as corners, edges of walls, and edges of obstacles that are difficult for traditional cleaning modules to reach.

[0022] This design cleverly utilizes the interaction forces of mechanical transmission to achieve multi-directional movement and rotation of the cleaning components with minimal space occupation and a simple structure, greatly expanding the cleaning range. Compared to traditional complex moving structures, the cleaning module of this application not only reduces manufacturing costs and complexity but also enhances the stability and durability of the equipment. Moreover, under the dual action of the swing arm's swing and its own rotation, the cleaning components can more thoroughly clean the floor, improving cleaning efficiency and quality, and bringing users a more convenient and efficient cleaning experience.

[0023] Meanwhile, this application mounts the drive component on the swing arm without requiring a fixed arm. A single drive component can both drive the cleaning component to swing and rotate, thus occupying less space in the main unit of the cleaning equipment compared to existing cleaning modules.

[0033] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] Traditional cleaning equipment often struggles to reach narrow spaces such as corners and furniture edges, resulting in incomplete cleaning and unsanitary areas. With continuous technological advancements, the cleaning equipment industry is constantly exploring new technological solutions. The extended cleaning component design is a significant achievement of this technological innovation, combining technologies from multiple fields such as mechanical structure and electronic control, bringing revolutionary changes to cleaning equipment. This extended design effectively expands the cleaning range, allowing the equipment to easily access and clean these hard-to-reach areas, thereby improving overall cleaning efficiency and coverage. Furthermore, different home or office environments have varying layouts and corners of various shapes and sizes; the extended cleaning component design can be flexibly adjusted to meet the needs of different scenarios, better adapting to various cleaning environments and enhancing the practicality and versatility of the cleaning equipment.

[0037] However, in existing cleaning equipment with external cleaning components, the external structure involved in the cleaning components is quite complex. For example, Chinese Patent Application No. CN202410022350.1 discloses a side brush module and cleaning equipment for a cleaning device, which includes a fixed arm, a swing arm, a power component, and a cleaning component. The power component includes an active component, a driven component, and a transmission component. The active component, driven component, and transmission component are all located on the swing arm. The drive component is connected to the active component, and the driven component and the cleaning component are respectively connected to the input and output ends of the transmission component. The active component moves under the drive of the drive component. During the movement, the active component drives the swing arm to swing through the driven component, thereby moving the cleaning component between a retracted position and an extended position. During the movement, the driven component can drive the cleaning component to rotate through the transmission component. In its disclosed technical solution, due to the limitation of the driving method of the power component, it is necessary to use a fixed arm as a basic structural component as a base for mounting the drive component and related structural components, which makes its overall solution more complex and occupies more installation space.

[0038] To address the aforementioned technical challenges, this embodiment provides a cleaning module, such as... Figures 1-7 As shown, the assembly includes: a base 1, a swing arm 2, a drive assembly 3, a first transmission assembly 4, and a cleaning assembly 5. The swing arm 2 is rotatably connected to the base 1. The drive assembly 3 is installed at one end of the swing arm 2, and the cleaning assembly 5 is installed at the other end of the swing arm 2. The output end of the drive shaft 301 of the drive assembly 3 is connected to the cleaning assembly 5 and can drive the cleaning assembly 5 to rotate. A limit member 201 is provided on the swing arm 2. The first transmission assembly 4 is connected to the output end of the drive shaft 301. Under the drive of the drive assembly 3, the first transmission assembly 4 can rotate around the drive shaft 301. During the rotation of the first transmission assembly 4, it can contact the limit member 201, causing the swing arm 2 to swing relative to the base 1, thereby causing the cleaning assembly 5 to move between a first cleaning position and a second cleaning position.

[0039] Based on the above scheme, the drive component 3 is directly installed at one end of the swing arm 2, while the cleaning component 5 is installed at the other end of the swing arm 2. The cleaning component 5 is connected to the output end of the drive shaft 301, enabling rotational cleaning. Simultaneously, the precise cooperation between the output end of the drive shaft 301 and the first transmission component 4 allows for flexible swinging of the swing arm 2. This design not only avoids the complex structure of traditional designs that require an additional fixed arm as a mounting base, but also greatly simplifies the overall structure, reduces unnecessary parts and installation space, making the cleaning module more compact and lightweight. Specifically, when the drive component 3 is activated, the driving force generated by the drive component 3 drives the first transmission component 4 to rotate around the drive shaft 301. During this process, a specific part of the first transmission component 4 contacts the limiting member 201 set on the swing arm 2, generating a torque that pushes the swing arm 2 to swing. As the swing arm 2 swings, the cleaning component 5 can extend outwards, covering hard-to-reach areas such as corners, edges, obstacles, or furniture edges for cleaning. Meanwhile, the output end of the drive shaft 301 also drives the cleaning component 5 to rotate through the transmission connection, realizing cleaning actions such as brushing, vacuuming, and mopping, further improving cleaning efficiency.

[0040] In summary, this design not only simplifies the structure but also improves transmission efficiency and flexibility. The direct connection between the output end of the drive shaft 301 and the first transmission component 4 ensures efficient power transmission and reduces energy loss, while the interaction between the swing arm 2 and the limiting member 201 makes the swing process smoother and more controllable, enhancing the stability and durability of the equipment. Furthermore, this design significantly improves cleaning performance, enabling the cleaning module to clean the floor more thoroughly, reducing hard-to-reach areas and providing users with a more convenient and efficient cleaning experience.

[0041] It should be noted that the vertical projection area of ​​the cleaning component 5 extending beyond the base 1 when it is in the first cleaning position is S1, and the vertical projection area of ​​the cleaning component 5 extending beyond the base 1 when it is in the second cleaning position is S2, where S1 > S2 and S2 ≥ 0. The first cleaning position can be understood as the outward expansion position of the cleaning component 5, and the second cleaning position is the retracted position of the cleaning component 5. However, in both cleaning positions, when the cleaning component 5 is in the retracted position, it includes not only the case where it is completely retracted into the vertical projection space of the base 1, but also the case where it is not completely retracted into the vertical projection space of the base 1. That is, the cleaning component 5 still extends beyond the base 1 and can still perform cleaning actions; however, the cleaning range of the cleaning component 5 in the second cleaning position is smaller than that in the first cleaning position.

[0042] Furthermore, the first transmission assembly 4 includes a swing member 401, a rotating shaft 402, and a friction member. The output end of the drive shaft 301 is provided with a drive gear 6. The friction member includes a first gear 403 and a friction wheel 404. One end of the swing member 401 is connected to the drive shaft 301, and the other end is connected to the rotating shaft 402. The first gear 403 and the friction wheel 404 are both connected to the rotating shaft 402. The first gear 403 meshes with the drive gear 6 and can drive the friction wheel 404 to rotate in the same direction. The inner wall surface of the base 1 is provided with a corrugated surface 101 that cooperates with the friction wheel 404 for transmission. In this scheme, the drive gear 6 meshes with the first gear 403, that is, the rotation direction of the first gear 403 is opposite to the rotation direction of the drive gear 6. The first gear 403 can drive the friction wheel 404 to rotate in the same direction. When the friction wheel 404 rotates, the outer peripheral wall of the friction wheel 404 can rub against the corrugated surface 101 on the inner wall of the base 1 to generate transmission. It can be understood that when the friction wheel 404 contacts the corrugated surface 101, the interaction force generated between the two is large enough to drive the entire first transmission assembly 4 to continue to rotate around the drive shaft 301. Therefore, the swing member 401 will contact the limiting member 201 on the swing arm 2 during the rotation process to form a hard connection, thereby pushing the swing arm 2 to swing, thereby realizing the position movement of the cleaning assembly 5. As one of the key components of this solution, the friction wheel 404 has its outer circumferential surface in close contact with the corrugated surface 101 of the inner wall of the base 1. When the friction wheel 404 rotates, the friction force on its outer circumferential surface interacts with the concave and convex structure of the corrugated surface 101, generating a thrust along the tangential direction of the inner wall of the base 1. This thrust is the key to driving the swing arm 2 to swing. It cleverly utilizes the principles of physical mechanics to convert the rotational motion into the swing of the swing arm 2, realizing the flexible movement of the cleaning component 5 in the horizontal direction.

[0043] It is worth noting that the pivot point between the swing arm 2 and the base 1 is coaxial with the drive shaft 301. The purpose of this design is so that when the swing component 401 pushes the limit component 201 to move, the swing arm 2 can swing around the drive shaft 301. The consistency of the axis makes the swing arm 2 swing more simply and smoothly.

[0044] Simultaneously, the first transmission component 4 is configured such that, driven by the drive gear 6, it rotates relative to the drive shaft 301 in a first clockwise direction. During the rotation of the first transmission component 4, the friction wheel 404 contacts the corrugated surface 101, causing the first gear 403 and the friction wheel 404 to rotate in a second clockwise direction, thereby driving the swing member 401 to rotate in the second clockwise direction. During the rotation of the swing member 401, the swing member 401 contacts the limiting member 201, thereby driving the swing arm 2 to swing in the first clockwise direction. During the above operation, before the friction wheel 404 contacts the corrugated surface 101, due to the damping friction between the first gear 403 and the rotating shaft 402, when the drive gear 6 rotates, it can drive the entire structure of the first transmission component 4 to rotate in the same direction as the drive gear 6. This can also be understood as the first transmission component 4 being able to rotate relative to the drive shaft 301 within a certain range, which is the range before the friction wheel 404 contacts the corrugated surface 101. When the friction wheel 404 comes into contact with the corrugated surface 101, the frictional force between the two enables the first gear 403 to overcome the frictional damping force between itself and the rotating shaft 402 and rotate. As the first gear 403 and the friction wheel 404 rotate, the frictional transmission between the friction wheel 404 and the corrugated surface 101 causes the first transmission assembly 4 to continue rotating. When the swing member 401 comes into contact with the limiting member 201, the swing member 401 moves against the limiting member 201, thereby driving the swing arm 2 to swing.

[0045] In this scheme, the key lies in the frictional contact between the friction wheel 404 and the corrugated surface 101. Without the frictional force between these two, the driving force provided by the drive wheel alone is insufficient to drive the swinging member 401 to push against the limiting member 201 and swing the swing arm 2. It is precisely because the frictional transmission between the friction wheel 404 and the corrugated surface 101 generates a sufficiently large interaction force that the swinging member 401 has enough force to drive the swing arm 2 to swing. When the friction wheel 404 disengages from the corrugated surface 101, the swing arm 2 will stop at the current position. However, since there is no fixed locking structure between the swing arm 2 and the base 1, the swing arm 2 can still swing slightly within a certain range. This swing is equivalent to providing an elastic buffer for the cleaning component 5. When the swing arm 2 swings to the point where the friction wheel 404 contacts the corrugated surface 101, the swing arm 2 will also be pushed to the set position by the swinging member 401.

[0046] As an optional specific implementation, the output end of the drive shaft 301 can be connected to a synchronous belt, which, along with a synchronous pulley, synchronously drives the cleaning component 5 to rotate and oscillate. The specific structure will not be described in detail here. Furthermore, other transmission structures capable of achieving the same function as the drive gear 6 should also fall within the scope of this application.

[0047] In some embodiments, the first transmission component 4 further includes a connector disposed between the first gear 403 and the friction wheel 404, so that the first gear 403 and the friction wheel 404 can rotate at the same speed. Specifically, the connector may be a snap-fit ​​structure or other locking structure that can fix the first gear 403 and the friction wheel 404. By fixing the first gear 403 and the friction wheel 404 together with the connector, the two can always ensure synchronous rotation in the same direction, which has strong structural stability and ensures consistent rotation, resulting in higher transmission efficiency.

[0048] As another optional specific implementation, the connecting member is disposed between the rotating shaft 402 and the friction wheel 404, so that the first gear 403 and the friction wheel 404 can rotate at different speeds. Specifically, the connecting member is an elastic member 405, which is disposed between the rotating shaft 402 and the friction wheel 404. Specifically, the bottom end of the rotating shaft 402 has a protrusion 4021, one end of the elastic member 405 abuts against the top surface of the protrusion 4021, and the other end abuts against the inner wall surface of the friction wheel 404. The elastic member 405 makes the friction wheel 404 always tend to move in the direction of the first gear 403, so as to increase the damping friction between the friction wheel 404 and the first gear 403. This damping friction needs to ensure that the first gear 403 and the friction wheel 404 rotate in the same direction or even synchronously, or at least in the same direction, so as to effectively drive the swing member 401 to swing, thereby realizing the swing of the swing arm 2. Since the first gear 403 and the friction wheel 404 are not fixedly connected, when the swing arm 2 swings to or towards the first cleaning position, if the cleaning component 5 collides with an obstacle or corner, the cleaning component 5 will be subjected to a reaction force that causes the friction wheel 404 to temporarily stop rotating. At this time, the first gear 403 continues to rotate, but the friction damping force provided by the elastic element 405 is insufficient to drive the friction wheel 404 to rotate again. At this time, the first transmission component 4 cannot continue to drive the swing arm 2 to swing, and the cleaning component 5 is in a relatively stopped position, which can effectively prevent the cleaning component 5 from continuing to swing and then colliding and causing damage. This is equivalent to providing a passive stopping protection for the cleaning component 5.

[0049] In some embodiments, the first transmission assembly 4 further includes a damping element disposed between the rotating shaft 402 and the first gear 403. This damping element increases the damping friction between the rotating shaft 402 and the first gear 403. When the friction wheel 404 separates from the corrugated surface 101, the drive shaft 301, through the drive gear 6, can drive the first transmission assembly 4 to rotate in the same clockwise direction. The damping element between the rotating shaft 402 and the first gear 403 ensures that the first gear 403 cannot rotate before the friction wheel 404 contacts the corrugated surface 101, thus allowing the drive gear 6 to drive the entire first transmission assembly 4 to rotate in the same direction.

[0050] The damping element can be a rubber damping ring, a metal damping plate, or an oil damper. Rubber damping rings are made of rubber, which is often used as a damping element due to its good elasticity and damping properties. The rubber damping ring can be fitted onto the connection between the shaft and the first gear, absorbing and dispersing vibration energy through its deformation.

[0051] Metal damping plates can utilize high-damping alloys, giving them excellent damping performance. The metal damping plate can be designed as a thin sheet, sandwiched between the rotating shaft and the first gear, utilizing the elastic deformation and internal friction of the metal to increase damping friction.

[0052] Oil dampers are a type of liquid damping device. They utilize the viscous resistance of oil to provide a damping effect by setting a chamber filled with damping oil between the shaft and the first gear. This method requires a sealing structure to prevent the damping oil from leaking.

[0053] Regarding the installation methods of damping components, at least direct mounting, recessed mounting, and adjustable mounting are included. Direct mounting: For rubber damping rings or metal damping plates, they can be directly mounted on the contact surface between the shaft and the first gear, and fastening screws or other fixing devices can be used to ensure that they do not fall off or shift.

[0054] Embedded mounting: A groove or hole may be designed in a part of the shaft or the first gear, into which the damping element can be embedded and fixed by interference fit or other means.

[0055] Adjustable installation: To more precisely control the magnitude of the damping force, an adjustable installation method can be adopted. For example, adjusting screws or spring mechanisms can be set on the damping plate. By adjusting these mechanisms, the contact pressure between the damping plate and the rotating shaft or the first gear can be changed, thereby adjusting the damping effect.

[0056] Specifically, during the process of the friction wheel 404 moving from contact to separation from the corrugated surface 101, the swing arm 2 switches between the first cleaning position and the second cleaning position. The first cleaning position is an outward expansion state, and the second cleaning position is a retracted state. The outward expansion state means that the cleaning component 5 extends relative to the main body of the device, and the retracted state means that the cleaning component 5 retracts into the main body of the device. The first clockwise direction can be either clockwise or counterclockwise, and the second clockwise direction is the opposite direction of the first clockwise direction. For easier understanding, the first clockwise direction is set to clockwise. When the cleaning component 5 is in the retracted state, the friction wheel 404 separates from the corrugated surface 101 of the base 1, the drive gear 6 rotates clockwise, and the first gear 403 and the friction wheel 404 rotate counterclockwise. When the cleaning component 5 begins to expand outward, the drive gear 6 rotates counterclockwise, causing the first transmission component 4 to rotate counterclockwise around the drive shaft 301 until the friction wheel 404 contacts the corrugated surface 101. At this time, the first gear 403 and the friction wheel 404 begin to rotate clockwise. When the swing member 401 rotates to contact the limiting member 201, under the friction transmission between the friction wheel 404 and the corrugated surface 101, the swing member 401 drives the swing arm 2 to swing counterclockwise until the friction wheel 404 and the corrugated surface 101 separate again, completing the expansion of the cleaning component 5.

[0057] Additionally, when the cleaning component 5 is in the extended position, the friction wheel 404 separates from the corrugated surface 101, the drive gear 6 rotates counterclockwise, and the first gear 403 and the friction wheel 404 rotate clockwise. When the cleaning component 5 begins to retract, the drive gear 6 rotates clockwise, causing the first transmission component 4 to rotate clockwise around the drive shaft 301 until the friction wheel 404 contacts the corrugated surface 101. At this time, the first gear 403 and the friction wheel 404 begin to rotate counterclockwise. When the swing member 401 rotates to contact the limiting member 201, under the friction transmission between the friction wheel 404 and the corrugated surface 101, the swing member 401 drives the swing arm 2 to swing clockwise until the friction wheel 404 separates from the corrugated surface 101 again, completing the retraction of the cleaning component 5.

[0058] It is worth mentioning that in the above scheme, the expansion of the cleaning component 5 is achieved by rotating the drive gear 6 counterclockwise, and vice versa, that is, the cleaning component 5 is expanded by rotating the drive gear 6 clockwise. The first clockwise direction is limited here for ease of understanding.

[0059] As another optional implementation, during the contact transmission process between the friction wheel 404 and the corrugated surface 101, the swing arm 2 switches between the first cleaning position and the second cleaning position. In this solution, it is not necessary to wait until the friction wheel 404 separates from the corrugated surface 101 before the cleaning component 5 can switch to the outward expansion state or the retraction state. Instead, the switching between the two states can be achieved throughout the entire friction transmission process. This requires further design and limitation of the shape and curvature of the corrugated surface 101 so that the swing arm 2 can swing to the preset position during the friction process.

[0060] Optionally, the limiting member 201 includes an arc-shaped limiting strip protruding from the swing arm 2 and / or the inner wall surface of the swing arm 2. The specific structure of the limiting member 201 is defined here, including three options: the first is that the limiting member 201 is an arc-shaped limiting strip; the second is that the limiting member 201 is the inner wall surface of the swing arm 2; and the third includes both an arc-shaped limiting strip and the inner wall surface of the swing arm 2. The choice of the specific structure of the limiting member 201 depends on the positional arrangement between the swing member 401 and the limiting member 201. When the swing range of the swing member 401 is small, the first or third option can be used, where the arc-shaped limiting strip and the inner wall surface of the swing arm 2 effectively abut against the swing member 401 to achieve transmission. When the swing member 401 can achieve a larger swing range, i.e., when the swing member 401 swings to both extreme positions and can contact the inner wall surface of the swing arm 2, the second option can be selected.

[0061] It is worth mentioning that the swing arm 2 includes an upper housing and a lower housing. The limiting member 201 can be located on the upper housing or not. In the above scheme, since the swing member 401 is located on the side close to the upper housing, the limiting member 201 needs to be located on the upper housing to ensure that the swing member 401 can contact the limiting member 201. It can also be understood that the specific location of the limiting member 201 depends on the installation position of the swing member 401, or the installation position of other structures in the first transmission assembly 4 that can contact the limiting member 201. That is, the limiting member 201 is not limited to being installed on the upper housing, but can also be installed on the lower housing according to the actual situation.

[0062] In some embodiments, a second transmission component 7 is further included. The input end of the second transmission component 7 is connected to the drive gear 6, and the output end is connected to the cleaning component 5. The second transmission component 7 is configured such that when the drive gear 6 rotates in a first clockwise direction or a second clockwise direction, the cleaning component 5 can be driven to rotate in the set direction via the transmission component 7. This solution can be simply understood as follows: even if the rotation direction of the drive gear 6 is changed, the cleaning component 5 can still maintain rotation in the same direction through the transmission connection of the second transmission component 7, thereby ensuring a high degree of cleanliness.

[0063] Specifically, the second transmission assembly 7 includes a second gear 701, a third gear 702, a fourth gear 703, a fifth gear 704, and a transmission gear set 705. The second gear 701 meshes with the drive gear 6, the third gear 702 is coaxially arranged with the second gear 701, the fourth gear 703 meshes with the second gear 701, and the fifth gear 704 is coaxially arranged with the fourth gear 703. The input end of the transmission gear set 705 meshes with either the third gear 702 or the fifth gear 704, and the output end is connected to the cleaning assembly 5. The second gear 701 and the fourth gear 703 are configured such that: the second gear 701 rotates in a first clockwise direction, and the second gear 701 moves axially and is keyed to the third gear 702, thereby driving the third gear 702 to rotate in the first clockwise direction; the second gear 701 rotates in a second clockwise direction, and the second gear 701 meshes with the fourth gear 703, thereby driving the fourth gear 703 to rotate in the first clockwise direction; the fourth gear 703 moves axially and is keyed to the fifth gear 704, thereby driving the fifth gear 704 to rotate in the first clockwise direction.

[0064] In the above scheme, both the second gear 701 and the fourth gear 703 are movable. When rotating clockwise, the second gear 701 can move axially to connect with the third gear 702 and rotate synchronously, and the fourth gear 703 can move axially to connect with the fifth gear 704 and rotate synchronously. Specifically, when the second gear 701 rotates clockwise, the third gear 702 rotates clockwise, driving the cleaning component 5 to rotate counterclockwise via the transmission gear set 705. At this time, the second gear 701 and the fourth gear 703 may still be in a meshing state, but the fourth gear 703 rotates counterclockwise without generating an axial position and cannot drive the fifth gear 704 to rotate; that is, the fifth gear 704 does not transmit power with the transmission gear set 705. When the second gear 701 rotates counterclockwise, it meshes with the fourth gear 703, causing the fourth gear 703 to rotate clockwise. This axial movement drives the fifth gear 704 to rotate clockwise, which in turn connects with the transmission gear set 705, causing the cleaning component 5 to rotate counterclockwise. Although the third gear 702 meshes with the transmission gear set 705 at this time, the third gear 702 has no rotational driving force and therefore cannot affect the transmission gear set 705. In summary, regardless of the direction in which the drive gear 6 rotates, the second transmission assembly 7 can drive the cleaning component 5 to rotate in the same direction.

[0065] The transmission gear set 705 includes a plurality of sequentially meshing transmission gears, and the specific number of transmission gears is adjusted according to the actual situation and is not specifically limited here.

[0066] Furthermore, the axial movement key connection between the second gear 701 and the fourth gear 703 is only one possible structural form. Other similar transmission structures that can achieve the above functions will not be described in detail here, but should fall within the protection scope of this solution.

[0067] Optionally, the cleaning component 5 can be a dry cleaning component or a wet cleaning component. Simply put, a wet cleaning component is used for mopping, while a dry cleaning component is used for sweeping. Specifically, the dry cleaning component is a side sweeper, which switches between an outward-expanding state and a retracting state to effectively clean hard-to-reach areas such as corners. The wet cleaning component includes a rotatable circular mop, a flat mop, or an irregularly shaped rotating mop.

[0068] On the other hand, a cleaning device is also provided, including a cleaning module, a main unit, and a moving module as described above. The moving module is located at the bottom of the main unit and is used to drive the main unit to move. The base 1 is part of the main unit or is directly the base of the main unit. By controlling the swing arm 2 to swing relative to the main unit, the cleaning component 5 is driven to move back and forth between different cleaning positions to achieve more efficient cleaning.
