Description

Technical Field

[0001] The present application relates to the technical field of cleaning modules, and in particular to a cleaning module and a cleaning device. Background Art

[0002] Cleaning equipment, also known as automatic sweepers, smart vacuums, or robot vacuums, is a type of smart home appliance that uses artificial intelligence to automatically clean floors. They typically use a brushing and vacuuming method to collect debris into their own waste collection bins, completing the cleaning process. Generally speaking, robots that perform sweeping, vacuuming, and mopping are also categorized as cleaning equipment.

[0003] At present, in order to increase the cleaning range, especially for hard-to-clean locations such as corners, cleaning equipment designs the cleaning components into a movable structure, so that the cleaning components can be extended relative to the main unit, making it easier for the cleaning components to effectively clean the hard-to-clean locations. However, the movable structures used in existing cleaning equipment are relatively complex and occupy too much installation space of the main unit. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a cleaning module and a cleaning device, which can stably realize the position movement of the cleaning component with a simple structure, so that the cleaning area of the cleaning component covers other difficult-to-clean corners such as wall corners, thereby improving the corner cleaning coverage rate without occupying too much space in the main body of the equipment.

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

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

[0011] Furthermore, the first transmission assembly further includes a connecting member, which is arranged 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 a differential speed.

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

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

[0014] Furthermore, the first transmission assembly also includes a damping member, which is arranged between the rotating shaft and the first gear, and is used to increase the damping friction force between the rotating shaft and the first gear. When the friction wheel is separated 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 to switch between the first cleaning position and the second cleaning position during the contact transmission between the friction wheel and the corrugated surface; or to switch between the first cleaning position and the second cleaning position during the movement from contact to separation between the friction wheel and the corrugated surface.

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

[0017] Furthermore, it also includes a second transmission assembly, the input end of the second transmission assembly is connected to the output end of the drive shaft, and the output end is connected to the cleaning assembly.

[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.

The device is mainly composed 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 a drive assembly installed at one end and a cleaning assembly at the other end. When the drive assembly is started, the drive shaft rotates accordingly, not only directly driving the cleaning assembly to perform a rotational cleaning action, but 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 limiter provided 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, so that the cleaning assembly can be flexibly moved to different positions in the room, especially those areas such as corners, walls, and obstacles that are difficult to reach with traditional cleaning modules.

[0022] This design cleverly utilizes the interaction force of mechanical transmission to achieve multi-directional movement and rotation of the cleaning component with minimal space occupation and the simplest structure, greatly expanding the cleaning range. Compared with traditional complex movable 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 component can clean the floor more comprehensively, improving cleaning efficiency and quality, and providing users with a more convenient and efficient cleaning experience.

[0023] At the same time, this application installs the driving component on the swing arm without the need for a fixed arm. One driving component can drive the cleaning component to swing and rotate. Compared with the existing cleaning module, it occupies less space in the main body of the cleaning equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0034] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0036] During the cleaning process, traditional cleaning equipment often has difficulty reaching narrow spaces such as corners and edges of furniture, resulting in incomplete cleaning and the existence of sanitary dead corners. With the continuous advancement of science and technology, the cleaning equipment industry is also constantly exploring new technical solutions. The outward-expanding design of the cleaning component is one of the important achievements of technological innovation. It combines technologies from multiple fields such as mechanical structure and electronic control, bringing revolutionary changes to cleaning equipment. The outward-expanding design of the cleaning component can effectively expand the cleaning range, allowing the equipment to easily enter and clean these hard-to-reach areas, thereby improving overall cleaning efficiency and coverage. Moreover, the layouts of different homes or office environments are different, and there are corners of various shapes and sizes. The outward-expanding design of the cleaning component can be flexibly adjusted according to the needs of different scenarios, better adapting to various cleaning environments, and improving the practicality and versatility of cleaning equipment.

[0037] However, in the existing cleaning equipment with an outward-expanding cleaning component, the outward-expanding structure involved in the cleaning component is relatively complex. For example, the Chinese patent application number CN202410022350.1 discloses a side brush module and a cleaning device for a cleaning device, which includes a fixed arm, a swing arm, a power assembly and a cleaning member. The power assembly further includes an active member, a driven member and a transmission assembly. The active member, the driven member and the transmission assembly are all arranged on the swing arm. The drive assembly is connected to the active member, and the driven member and the cleaning member are respectively connected to the input end and the output end of the transmission assembly. The active member moves under the drive of the drive assembly. During the operation, the active member drives the swing arm to swing through the driven member to drive the cleaning member to move between the retracted position and the extended position, and the driven member can drive the cleaning member to rotate through the transmission assembly during the operation. In the technical solution disclosed therein, due to the limitation of the driving mode of the power assembly, it is necessary to use the fixed arm as a basic structural member as a base for installing the drive assembly and related structural members, which makes its overall solution more complicated and occupies a larger installation space.

[0038] In view of the above technical difficulties, this embodiment provides a cleaning module, such as Figure 1-Figure 7 As shown, it includes: a base 1, a swing arm 2, a driving component 3, a first transmission component 4 and a cleaning component 5; the swing arm 2 is rotatably connected to the base 1, the driving component 3 is installed at one end of the swing arm 2, and the cleaning component 5 is installed at the other end of the swing arm 2. The output end of the driving shaft 301 of the driving component 3 is connected to the cleaning component 5 and can drive the cleaning component 5 to rotate; a limiting member 201 is provided on the swing arm 2, and the first transmission component 4 is connected to the output end of the driving shaft 301. The first transmission component 4 can rotate around the driving shaft 301 under the drive of the driving component 3, and can contact the limiting member 201 during the rotation of the first transmission component 4, thereby driving the swing arm 2 to swing relative to the base 1, and then driving the cleaning component 5 to move between the first cleaning position and the second cleaning position.

[0039] Based on the above scheme, the drive component 3 is directly installed at one end of the swing arm 2, and 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 to realize the rotational cleaning of the cleaning component 5. At the same time, the precise cooperation between the output end of the drive shaft 301 and the first transmission component 4 realizes the flexible swinging of the swing arm 2. This design not only avoids the complex structure of the traditional design that requires an additional fixed arm as a mounting base, but also greatly simplifies the overall structure, reduces unnecessary components and installation space, and makes the cleaning module more compact and lightweight. Specifically, when the drive component 3 is started, the driving force generated by the drive component 3 drives the first transmission component 4 to rotate as a whole around the drive shaft 301. During this process, a specific part of the first transmission component 4 contacts the limiter 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 expand outward to cover hard-to-reach areas such as corners, wall edges, obstacles or furniture edges for cleaning. At the same time, the output end of the drive shaft 301 also drives the cleaning component 5 to rotate itself through a transmission connection, thereby realizing cleaning actions such as brushing, vacuuming, and mopping, thereby further improving the cleaning efficiency.

[0040] Overall, this solution 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 assembly 4 ensures efficient power transmission and reduces energy loss. The interaction between the swing arm 2 and the limiter 201 makes the swinging process smoother and more controllable, enhancing the stability and durability of the device. Furthermore, this design significantly improves cleaning effectiveness, enabling the cleaning module to more comprehensively clean the floor, reducing blind spots 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 out of the base 1 when it is in the first cleaning position is S1, and the vertical projection area of the cleaning component 5 extending out of the base 1 when it is in the second cleaning position is S2, where S1>S2, and S2≥0. Among them, the first cleaning position can be understood as the outward expansion position of the cleaning component 5, and the second cleaning position is the recovery position of the cleaning component 5. However, in these two cleaning positions, when the cleaning component 5 is in the recovery position, the cleaning component 5 not only includes the situation where it is completely recovered into the vertical projection space of the base 1, but also includes the situation where it is not completely recovered into the vertical projection space of the base 1, that is, the cleaning component 5 still partially extends out of the base 1 and can still perform cleaning actions, but the cleaning range of the cleaning component 5 in the second cleaning position is smaller than the cleaning range in the first cleaning position.

[0042] Furthermore, the first transmission assembly 4 includes a swinging member 401, a rotating shaft 402 and a friction member. The output end of the drive shaft 301 is provided with a driving gear 6. The friction member includes a first gear 403 and a friction wheel 404. One end of the swinging 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 is engaged with the driving 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 driving gear 6 is engaged with the first gear 403, that is, the rotation direction of the first gear 403 is opposite to the rotation direction of the driving gear 6, and 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 frictionally contact 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 component 4 to continue to rotate around the drive shaft 301. Therefore, the swing member 401 will contact the limit member 201 on the swing arm 2 during the rotation process to form a hard connection, and then push the swing arm 2 to swing, thereby realizing the position movement of the cleaning component 5. The friction wheel 404 is one of the key elements of this solution. Its outer peripheral surface is tightly matched with the corrugated surface 101 of the inner wall of the base 1. When the friction wheel 404 rotates, the friction force of its outer peripheral surface will interact with the concave-convex structure of the corrugated surface 101 to generate 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, thereby realizing the flexible movement of the cleaning component 5 in the horizontal direction.

[0043] It is worth noting that the rotation fulcrum between the swing arm 2 and the base 1 is coaxial with the drive shaft 301. The purpose of this design is that when the swing member 401 pushes the limit member 201 to move, the swing arm 2 can swing with the drive shaft 301 as the axis. The consistency of the axis can make the swing of the swing arm 2 simpler and smoother.

[0044] At the same time, the first transmission assembly 4 is configured such that: driven by the drive gear 6, the first transmission assembly 4 rotates relative to the drive shaft 301 in a first clockwise direction. During the rotation of the first transmission assembly 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 stop member 201, thereby driving the swing arm 2 to swing in the first clockwise direction. During the above-mentioned 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, the rotation of the drive gear 6 can drive the entire structure of the first transmission assembly 4 to rotate in the same direction as the drive gear 6. It can also be understood that the first transmission assembly 4 can rotate relative to the drive shaft 301 within a certain range, and this certain range is before the friction wheel 404 contacts the corrugated surface 101. When the friction wheel 404 comes into contact with the corrugated surface 101, the friction force between the two enables the first gear 403 to overcome the friction damping force between the first gear 403 and the rotating shaft 402 and rotate. As the first gear 403 and the friction wheel 404 rotate, the friction transmission between the friction wheel 404 and the corrugated surface 101 is generated, and the first transmission assembly 4 continues to rotate. When the swinging member 401 comes into contact with the limit member 201, the swinging member 401 moves against the limit member 201, thereby driving the swing arm 2 to swing.

[0045] The key to this solution lies in the frictional contact between the friction wheel 404 and the corrugated surface 101. Without the frictional force between the two, the driving force provided by the drive wheel alone would not be sufficient to drive the swing member 401 against the limit member 201 to achieve the swing arm 2's swing. It is precisely because of the frictional transmission between the friction wheel 404 and the corrugated surface 101 that the interaction force generated is large enough to ensure that the swing 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 its 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 be pushed to the set position by the swing member 401.

[0046] As an optional embodiment, the output end of the drive shaft 301 can be connected to a synchronous belt, which can synchronously drive the cleaning assembly 5 to rotate and swing through the synchronous belt and synchronous wheel. The specific structure is not described here. In addition, other transmission structures that can achieve the same function as the drive gear 6 should also fall within the scope of protection of this application.

[0047] In some embodiments, the first transmission assembly 4 further includes a connecting member, which is arranged 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, wherein the connecting member can specifically be a snap-fit structure or other locking structure that can fixedly connect the first gear 403 and the friction wheel 404. The first gear 403 and the friction wheel 404 are fixedly connected by the connecting member, so that the two can always ensure synchronous rotation in the same direction, have strong structural stability, and can ensure consistency in rotation, and have higher transmission efficiency.

[0048] As another optional embodiment, the connecting member is disposed between the rotating shaft 402 and the friction wheel 404 to enable differential rotation of the first gear 403 and the friction wheel 404. Specifically, the connecting member is an elastic member 405 disposed between the rotating shaft 402 and the friction wheel 404. Specifically, a boss 4021 is provided at the bottom end of the rotating shaft 402. One end of the elastic member 405 abuts against the top surface of the boss 4021, and the other end abuts against the inner wall of the friction wheel 404. The elastic member 405 ensures that the friction wheel 404 always has a tendency to move toward the first gear 403, thereby increasing the damping friction between the friction wheel 404 and the first gear 403. This damping friction is required 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 achieving 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 the first cleaning position or swings toward the first cleaning position, when the cleaning component 5 collides with an obstacle or a corner, the cleaning component 5 will be subjected to a reaction force causing the friction wheel 404 to temporarily stop rotating. At this time, the first gear 403 is still rotating, but the friction damping force provided by the elastic member 405 is not enough to drive the friction wheel 404 to rotate. At this time, the first transmission component 4 can no longer 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 to cause damage, which is equivalent to providing a passive stop protection for the cleaning component 5.

[0049] In some embodiments, the first transmission assembly 4 further includes a damping member disposed between the rotating shaft 402 and the first gear 403 to increase 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, via the drive gear 6, can drive the first transmission assembly 4 to rotate in the same clockwise direction. The damping member disposed 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, thereby enabling 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. The rubber damping ring is made of rubber material, which is often used as a damping element due to its excellent elasticity and damping properties. The rubber damping ring can be mounted at the connection between the rotating shaft and the first gear, absorbing and dissipating vibration energy through its deformation.

[0051] The metal damping plate can be made of a high-damping alloy to provide excellent damping performance. The metal damping plate can be designed as a thin sheet and sandwiched between the rotating shaft and the first gear, utilizing the elastic deformation and internal friction of the metal to increase the damping friction force.

[0052] The oil damper is a liquid damping method that provides a damping effect by setting a chamber filled with damping oil between the rotating shaft and the first gear and utilizing the viscous resistance of the oil. This method requires a sealing structure to prevent leakage of the damping oil.

[0053] The damping element installation methods include at least direct installation, embedded installation, and adjustable installation. Direct installation: For rubber damping rings or metal damping sheets, they can be directly installed on the contact surface between the rotating shaft and the first gear, and secured against falling off or shifting by tightening screws or other fixing devices.

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

[0055] Adjustable mounting: To more precisely control the damping force, an adjustable mounting method can be used. For example, an adjustment screw or spring mechanism can be installed 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 and the corrugated surface 101 moving from contact to separation, the swing arm 2 switches between the first cleaning position and the second cleaning position, wherein the first cleaning position is an outward-expanding state and the second cleaning position is a retracted state. The outward-expanding state means that the cleaning component 5 extends relative to the device body, and the retracted state means that the cleaning component 5 is retracted into the device body. The first clockwise direction can be clockwise or counterclockwise, and the second clockwise direction is a rotation direction opposite to the first clockwise direction. For easier understanding, the first clockwise direction is set here as the clockwise direction. 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 starts to expand outward, the driving gear 6 rotates counterclockwise, driving the first transmission component 4 to rotate counterclockwise around the driving shaft 301 until the friction wheel 404 contacts the corrugated surface 101. At this time, the first gear 403 and the friction wheel 404 start to rotate clockwise. When the swinging member 401 rotates to contact the limit member 201, under the friction transmission between the friction wheel 404 and the corrugated surface 101, the swinging member 401 drives the swing arm 2 to swing counterclockwise until the friction wheel 404 separates from the corrugated surface 101 again, completing the expansion of the cleaning component 5.

[0057] Furthermore, when the cleaning assembly 5 is in the outwardly 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 assembly 5 begins to retract, the drive gear 6 rotates clockwise, driving the first transmission assembly 4 to rotate clockwise around the drive shaft 301 until the friction wheel 404 contacts the corrugated surface 101. At this point, the first gear 403 and the friction wheel 404 begin to rotate counterclockwise. When the swinging member 401 rotates until it contacts the stopper 201, the friction between the friction wheel 404 and the corrugated surface 101 causes the swinging member 401 to swing clockwise until the friction wheel 404 separates from the corrugated surface 101 again, completing the retraction of the cleaning assembly 5.

[0058] It is worth mentioning that in the above solution, the outward expansion of the cleaning component 5 is achieved by counterclockwise rotation of the driving gear 6, and vice versa is also possible, that is, the cleaning component 5 is driven to expand outward by clockwise rotation of the driving gear 6. Here, the first clockwise direction is limited only for the convenience of understanding.

[0059] As another optional embodiment, the swing arm 2 switches between the first cleaning position and the second cleaning position during the contact transmission between the friction wheel 404 and the corrugated surface 101. In this solution, the cleaning assembly 5 does not need to wait until the friction wheel 404 separates from the corrugated surface 101 before switching to the expanded state or the retracted state. Instead, the switching between the two states can be achieved during the entire friction transmission process. This requires further design and definition of the shape and curvature of the corrugated surface 101 so that the swing arm 2 can be driven to 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 option is that the limiting member 201 is an arc-shaped limiting strip, the second option is that the limiting member 201 is the inner wall surface of the swing arm 2, and the third option is that it includes both the arc-shaped limiting strip and the inner wall surface of the swing arm 2. As for how to choose the specific structure of the limiting member 201, it depends on the position 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 adopted, and the transmission is achieved by effectively contacting the arc-shaped limiting strip and the inner wall surface of the swing arm 2 with the swing member 401; and when the swing member 401 can achieve a larger swing range, that is, the swing member 401 can contact the inner wall surface of the swing arm 2 when it swings to the two extreme positions, then the second option can be selected.

[0061] It is worth mentioning that the swing arm 2 includes an upper shell and a lower shell, and the limiter 201 can be set on the upper shell or the lower shell. In the above solution, since the swing member 401 is set on the side close to the upper shell, in order to ensure that the swing member 401 can contact the limiter 201, the limiter 201 needs to be set on the upper shell. It can also be understood that the specific location of the limiter 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 limiter 201, that is, the limiter 201 is not limited to being installed on the upper shell, and can also be installed on the lower shell according to actual conditions.

[0062] In some embodiments, a second transmission assembly 7 is further included. The input end of the second transmission assembly 7 is connected to the drive gear 6, and the output end is connected to the cleaning assembly 5. The second transmission assembly 7 is configured such that when the drive gear 6 rotates in a first clockwise direction or a second clockwise direction, the cleaning assembly 5 can be driven to rotate in a set direction through the second transmission assembly 7. This solution can be simply understood as follows: even if the rotation direction of the drive gear 6 changes, the cleaning assembly 5 can still maintain rotation in the same direction due to the transmission connection of the second transmission assembly 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 is meshed with the driving gear 6, the third gear 702 is coaxially arranged with the second gear 701, the fourth gear 703 is meshed 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 is respectively meshed with 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 as follows: the second gear 701 rotates along the first clockwise direction, the second gear 701 moves axially and is key-connected to the third gear 702, driving the third gear 702 to rotate along the first clockwise direction; the second gear 701 rotates along the second clockwise direction, the second gear 701 engages with the fourth gear 703 and drives the fourth gear 703 to rotate along the first clockwise direction, the fourth gear 703 moves axially and is key-connected to the fifth gear 704, driving the fifth gear 704 to rotate along the first clockwise direction.

[0064] In the above scheme, the second gear 701 and the fourth gear 703 are both movable. When both are set to rotate clockwise, the second gear 701 can move axially to connect with the third gear 702 to drive synchronous rotation, and the fourth gear 703 can move axially to connect with the fifth gear 704 to rotate synchronously. Specifically, when the second gear 701 rotates clockwise, the third gear 702 rotates clockwise, driving the cleaning component 5 to rotate counterclockwise through the transmission gear set 705. At this time, the second gear 701 and the fourth gear 703 can still be in a meshing state, but the fourth gear 703 rotates counterclockwise and does not produce an axial position, and cannot drive the fifth gear 704 to rotate. In other words, the fifth gear 704 is not transmitting to 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. The axial movement drives the fifth gear 704 to rotate clockwise, which in turn connects with the transmission gear set 705, driving the cleaning assembly 5 to rotate counterclockwise. At this time, although the third gear 702 is meshed with the transmission gear set 705, the third gear 702 has no rotational driving force and therefore cannot affect the transmission gear set 705. In short, no matter which direction the driving gear 6 rotates, the cleaning assembly 5 can be driven to rotate in the same direction through the second transmission assembly 7.

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

[0066] In addition, the axially movable key connection between the second gear 701 and the fourth gear 703 is only one of the feasible structural forms. Other similar transmission structures that can achieve the above functions will not be described here one by one, but should fall within the protection scope of this solution.

[0067] Optionally, the cleaning component 5 is a dry cleaning element or a wet cleaning element. Simply put, the wet cleaning element is used for mopping, while the dry cleaning element is used for sweeping. The dry cleaning element is specifically a side sweeper, which switches between an outward-expanding state and a retracting state to effectively clean difficult-to-reach areas such as corners. The wet cleaning element includes a rotatable round 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 body and a mobile module as described above. The mobile module is arranged at the bottom of the main body and is used to drive the main body to move. The base 1 is a part of the main body or is directly the base of the main body. By controlling the swing arm 2 to swing relative to the main body, the cleaning component 5 is driven to move back and forth between different cleaning positions to achieve more efficient cleaning.
