Description

Technical Field

[0001] This disclosure relates to the technical field of cleaning tools, and more particularly to a cleaning device. Background Technology

[0002] Cleaning equipment can sweep and recycle stains on surfaces to be cleaned, greatly freeing up users' hands and bringing great convenience to people.

[0003] The bottom of the cleaning equipment is equipped with different types of cleaning components, such as side brushes, rollers, and cloths. In some cases, the space is too small for the main body of the cleaning equipment to fit into. Therefore, the cleaning components need to be extended laterally by the swing arm to enter the confined space for cleaning.

[0004] In the existing technology, the swing of the swing arm and the movement of the cleaning parts need to be powered by different drive motors, which increases the number of motors, and in particular, increases the space occupied, material costs, and design costs. Utility Model Content

[0005] One of the technical problems that this disclosure aims to solve is that the swing arm and cleaning components are driven by multiple motors, which occupy a large space and have high material costs.

[0006] To address the aforementioned technical problems, this disclosure provides a cleaning device, comprising a body, a cleaning component, and a motion mechanism. The cleaning component is movably connected to the motion mechanism to have an inward retracted position and an outward swing position. The motion mechanism includes a base, a drive component mounted on the base, a clutch, and a swing arm oscillatingly connected to the base. The swing arm is equipped with a swing gear and a first transmission assembly. The first transmission assembly connects to the cleaning component and drives it to rotate and / or lift. The drive component is drively connected to the first transmission assembly and the input end of the clutch, and the output end of the clutch is drively connected to the swing gear.

[0007] The drive unit is capable of operating at a first speed and a second speed. At the first speed, the input and output ends of the clutch are disconnected, and the drive unit drives the first transmission assembly to rotate and / or lift the cleaning component. At the second speed, the input and output ends of the clutch are connected, so as to drive the swing arm to swing relative to the base through the swing gear, thereby driving the cleaning component to move between an inward position and an outward position.

[0008] In some embodiments, the second rotational speed is greater than the first rotational speed. At the second rotational speed, the clutch drives the input and output ends of the clutch to connect through centrifugal force.

[0009] In some embodiments, the clutch includes a rotating shaft driven to the drive member, a radially extending support beam connected to the rotating shaft, a slider radially slidably disposed on the support beam, and a gear ring coaxially disposed with the rotating shaft and meshing with the oscillating gear. At a first rotational speed, the slider disengages from the gear ring, and at a second rotational speed, the slider engages with the gear ring, and the rotating shaft can drive the gear ring to rotate.

[0010] In some embodiments, a recess is provided on the inner circumference of the gear ring, and a protrusion is provided on the slider that can be inserted into the recess; or, a protrusion is provided on the inner circumference of the gear ring, and a recess is provided on the slider that can accommodate the insertion of the protrusion.

[0011] In some embodiments, the clutch includes a force-applying element, at least two support beams extending in opposite directions, and at least two corresponding sliders. The force-applying element is an elastic element connecting the two sliders. The force-applying element applies a radially inward force to the sliders. At the second rotational speed, the centrifugal force of the sliders is greater than the force of the force-applying element.

[0012] In some embodiments, the first transmission assembly includes a lifting structure, the cleaning component is connected to the lifting structure, and the driving component drives the first transmission assembly to move.

[0013] The driving component has a first rotation direction and a second rotation direction. When the driving component rotates in the first rotation direction, the lifting structure drives the cleaning component to perform a downward movement or a cleaning rotation movement. When the driving component rotates in the second rotation direction, the lifting structure drives the cleaning component to perform an upward movement.

[0014] In some embodiments, the first transmission assembly further includes a second transmission gear, one axial end of which is provided with a cavity, and the lifting structure is tractively connected to the second transmission gear and is used to detachably connect the cleaning component, wherein the first end of the lifting structure is provided in the cavity.

[0015] In some embodiments, the lifting structure includes a first bushing coaxially connected to the second transmission gear and a second bushing coaxially sleeved on the first bushing. The first bushing and the second bushing are threadedly engaged. When the driving member drives the second transmission gear to rotate in the forward direction, the second bushing can move axially from the upper limit position to the lower limit position. At the lower limit position, the first bushing drives the second bushing to rotate in the forward direction so that the cleaning member can rotate for cleaning. When the driving member drives the second transmission gear to rotate in the reverse direction, the second bushing can move axially from the lower limit position to the upper limit position to lift the cleaning member.

[0016] In some embodiments, a magnetic element is provided in the second bushing, and the cleaning element is connected to the second bushing via the magnetic element.

[0017] In some embodiments, the swing arm is rotatable relative to the base about a first axis to give the cleaning member an inward position and an outward position; the cleaning member is rotatable relative to the swing arm about a second axis to give the cleaning member a rotational cleaning function; when the cleaning member is in the inward position, the first axis is positioned relative to the second axis near the outer edge of the body in the width direction of the body.

[0018] The above technical solution allows for selective swinging of the swing arm via a clutch. Therefore, it is possible to achieve the swinging of the swing arm and the rotation and lifting of the cleaning component using only a single drive unit. This eliminates the need for three separate drive units for the swinging of the swing arm, the rotation of the cleaning component, and the lifting of the cleaning component, thus reducing the number of drive units. On the one hand, the control of the drive units is simpler; on the other hand, the structure of the equipment is also simplified, resulting in a significant reduction in the space occupied. This saves more space for the equipment and also reduces material and equipment costs. Attached Figure Description

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0035] When using cleaning equipment to clean rooms and other places, the problem of cleaning corners and edges is encountered. These areas are narrow and it is not convenient for the main body of the cleaning equipment to enter them. Therefore, it is necessary to set up an outward swing module for the cleaning equipment to swing the cleaning parts outward and extend them into these narrow spaces. However, the outward swing module occupies a lot of space, which is not conducive to the overall design of the cleaning equipment. Therefore, it is necessary to reduce its space occupation and improve the overall integration of the equipment, such as reducing the number of motors. To this end, this application proposes the following design solution.

[0036] refer to Figures 1-6As shown, this solution discloses a cleaning device, which includes a body 50, a cleaning component, and a motion mechanism. The cleaning component is movably connected to the motion mechanism to have an inward retracted position and an outward swing position. The motion mechanism includes a base 10, a drive component 20 disposed on the base 10, a clutch 30, and a swing arm 40 oscillatingly connected to the base 10. The swing arm 40 is provided with a swing gear 41 and a first transmission assembly. The first transmission assembly can connect to the cleaning component and drive the cleaning component to rotate and / or lift. The drive component 20 is drively connected to the first transmission assembly and the input end of the clutch 30, and the output end of the clutch 30 is drively connected to the swing gear 41.

[0037] The drive unit 20 can operate at a first speed and a second speed. At the first speed, the input and output ends of the clutch 30 are disconnected, and the drive unit drives the first transmission assembly to rotate and / or lift the cleaning component. At the second speed, the input and output ends of the clutch 30 are connected, so that the swing arm 40 swings relative to the base 10 through the swing gear 41, thereby moving the cleaning component between an inward position and an outward position.

[0038] The cleaning equipment includes a body 50 and cleaning components. The cleaning components can move relative to each other to perform cleaning actions, such as rotation and lifting. Generally, the cleaning components are located at the bottom of the body 50 and move with the body 50 to clean the ground. In some cases, the space occupied by some surfaces to be cleaned is relatively small, or due to structural limitations of the cleaning equipment, the body 50 cannot reach these surfaces, such as areas near obstacles. Therefore, it is necessary for the cleaning components to swing outward from the body 50 and extend to these surfaces to be cleaned, for example, to perform edge cleaning on the edges of some obstacles, in order to reduce or avoid cleaning omissions along the edges of obstacles. In other words, the cleaning components need to move between an inward-swinging position and an outward-swinging position to adapt to different cleaning needs.

[0039] It can be seen that the movement of the cleaning component mainly includes rotation, lifting, and oscillation: the oscillation of the cleaning component relative to the body 50 around the first axis allows it to swing outward to reach into narrow spaces such as corners for cleaning, or swing back into the body 50 to clean the lower surface of the body 50; when the cleaning component rotates around the vertical second axis, it can clean the surfaces it contacts; the lifting movement of the cleaning component relative to the body 50 can adjust its height, allowing it to descend to a position contacting the surface to be cleaned or to detach from the surface to be cleaned. The first and second axes can be parallel to each other.

[0040] In the existing technology, the lifting, rotating and the movement between the inward and outward positions of the cleaning component itself each require a motor or drive component to drive them. The number of motors is relatively large, which increases material costs and space occupation.

[0041] In this solution, a motion mechanism is designed for the cleaning component. On the one hand, it can drive the component to move up and down and rotate. On the other hand, it can selectively drive the component to move between the inward position and the outward position.

[0042] Specifically, the motion mechanism includes a base 10, a swing arm 40, a drive component 20, and a clutch 30. The base 10 serves as the basic structure, providing support for other components. The base 10, swing arm 40, drive component 20, and clutch 30 form a modular structure, facilitating installation and disassembly, and promoting structural layout design, improving integration, and reducing space occupation. Furthermore, the swing arm 40, drive component 20, and clutch 30, mounted on the base 10, ensure more stable operation and guarantee the stability and reliability of the overall structure. After being installed on the body 50 of the cleaning equipment, the base 10 remains relatively fixed relative to the body 50.

[0043] The drive component 20 can be an electric motor, hydraulic motor, etc., preferably an electric motor, which is a power structure that can provide torque power to other structures.

[0044] The swing arm 40 is rotatably connected to the base 10 and can be fitted with a detachable cleaning component. The rotation of the swing arm 40 relative to the base 10 is for moving the cleaning component relative to the base 10, i.e., the body 50 of the cleaning device. In the initial state, the swing arm 40 can be retracted into the body 50 (it can be partially extended due to volume limitations). When it is necessary to clean the surface of a narrow space that is far from the body 50, the swing arm 40 swings outward about a vertical first axis, so that the cleaning component on it can reach the narrow space to achieve cleaning of the surface.

[0045] In addition, the swing arm 40 is also provided with a first transmission component for driving the movement of the cleaning component. The power of the driving component 20 is transmitted to the cleaning component through the first transmission component so that the cleaning component can move and thus clean the surface.

[0046] It can be seen that the swing of the swing arm 40 and the movement of the cleaning component are both achieved by the power of the drive component 20. Furthermore, it can be known that during the cleaning process, the swing arm 40 does not need to maintain a swing state at all times. That is, after swinging outward to a suitable position, the power to swing the swing arm 40 needs to be stopped.

[0047] The swing arm 40 may include a swing arm housing 48, on the outside of which a relatively fixed swing gear 41 is disposed. A clutch 30 is also disposed on the base 10. The drive member 20 is drivenly connected to the input end of the clutch 30, and the output end of the clutch 30 is drivenly connected to the swing gear 41. The clutch 30 can be controlled to switch between a driving state and a non-driving state. In the driving state, its input and output ends are drivenly connected, so power can be transmitted to the swing gear 41, thereby driving the swing arm 40 to swing relative to the base 10. In the non-driving state, its input and output ends are disconnected, and the swing gear 41 cannot be driven to rotate relative to the base 10, that is, it cannot drive the swing arm 40 to swing. Of course, the drive member 20 can drive the cleaning member to move through the first transmission component to realize the cleaning action.

[0048] The state change of the clutch 30 is achieved by the rotational speed of the drive component 20. That is, at the first rotational speed, the clutch 30 disengages the transmission connection and only drives the first transmission component of the swing arm 40 to move (to drive the cleaning component to move). At the second rotational speed, the swing arm 40 can be driven to swing and the first transmission component can be driven to move simultaneously. Of course, this is mainly to swing the swing arm 40 to a suitable angle, including swinging the swing arm 40 outward and retracting it inward, so that different positions can be cleaned.

[0049] In this solution, the swing arm can be selectively driven to swing using a clutch. Therefore, it is possible to achieve the swing of the swing arm and the rotation and lifting of the cleaning component using only a single drive unit. This eliminates the need for three separate drive units for the swing of the swing arm, the rotation of the cleaning component, and the lifting of the cleaning component, thus reducing the number of drive units. On the one hand, the control of the drive units is simpler. On the other hand, the structure of the equipment is also simplified, resulting in a significant reduction in the space occupied. This saves more space for the equipment and also reduces material and equipment costs.

[0050] In some embodiments, the second rotational speed is greater than the first rotational speed. At the second rotational speed, the clutch 30 drives the input and output ends of the clutch 30 through centrifugal force. The clutch 30 may include a component that can rotate around a central axis and slide radially. When the drive component 20 increases from the first rotational speed to the second rotational speed, this component slides radially outward, thus enabling the clutch 30 to switch states, i.e., from a non-transmission state to a transmission state. Changing the state of the clutch 30 through centrifugal force only requires a change in rotational speed, making operation simple, eliminating the need for complex control structures, simplifying the structure, reducing space requirements, and lowering costs.

[0051] In some embodiments, the clutch 30 includes a rotating shaft 31 driveably connected to the drive member 20, a radially extending support beam 32 connected to the rotating shaft 31, a slider 33 radially slidably disposed on the support beam 32, and a gear ring 34 coaxially disposed with the rotating shaft 31 and meshing with the oscillating gear 41. At a first rotational speed, the slider 33 disengages from the gear ring 34; at a second rotational speed, the slider 33 engages with the gear ring 34, and the rotating shaft 31 can drive the gear ring 34 to rotate. (Reference) Figure 4 As shown, the clutch 30 includes a rotating shaft 31, a support beam 32, a slider 33, and a gear ring 34. The rotating shaft 31 can be directly connected to the drive component 20, or it can be connected via a transmission component such as a transmission gear, chain, or belt. The support beam 32 is connected to the rotating shaft 31 and extends radially. The slider 33 is radially slidably mounted on the support beam 32 and can rotate synchronously with it. The gear ring 34 is coaxially mounted with the rotating shaft 31 and meshes with the oscillating gear 41. When the drive component 20 rotates at a first speed, the rotational speed of the rotating shaft 31 is relatively low, and the centrifugal force on the slider 33 is small. Therefore, the slider 33 will not move radially outward to the position where it engages with the gear ring 34, and thus will not drive the gear ring 34 to rotate. When the rotational speed of the drive component 20 increases to a second speed, the slider 33 moves radially outward under a greater centrifugal force to the position where it engages with the gear ring 34, thereby driving the gear ring 34 to rotate. The gear ring 34 then correspondingly drives the oscillating gear 41 and the swing arm 40 to swing. It can be seen that the structure of the clutch 30 is relatively simple. The state change of transmission and disconnection can be realized through the cooperation of the rotating shaft 31, the support beam 32, the slider 33 and the gear ring 34. It does not require a complex control structure. The state change can be realized by changing the speed. It is easy to process and manufacture and has low cost.

[0052] In other embodiments, the gear ring 34 can be configured in a form similar to the slider 33. The gear ring 34 can slide radially along the support beam 32. When the rotational speed is low, it does not mesh with the oscillating gear 41. When the rotational speed increases, the gear ring 34 slides radially outward and meshes with the oscillating gear 41.

[0053] Understandably, the rotation direction of the drive component 20 can be changed, thereby allowing the swing arm 40 to swing in the opposite direction, achieving swinging out and retraction.

[0054] In some embodiments, the inner circumference of the gear ring 34 is provided with a recess, and the slider 33 is provided with a protrusion that can be inserted into the recess; or, the inner circumference of the gear ring 34 is provided with a protrusion, and the slider 33 is provided with a recess that can accommodate the insertion of the protrusion. When the rotational speed increases, the slider 33 moves radially outward, allowing the protrusion to be inserted into the recess, thus fixing the gear ring 34 and the slider 33 relatively in the circumferential direction. Therefore, the gear ring 34 can be driven to rotate around the central axis of the rotating shaft 31. The protrusion (not shown in the figure) can be provided on the gear ring 34 or the slider 33, and correspondingly, the recess can be provided on the slider 33 or the gear ring 34. Through the cooperation of the protrusion and the recess, the slider 33 and the gear ring 34 can be more firmly joined, avoiding slippage between them and ensuring stable torque transmission. Of course, in other embodiments, the circumferential relative fixation between the slider 33 and the gear ring 34 can also be achieved by the friction between them.

[0055] In some embodiments, the clutch 30 includes a force-applying element 35, at least two support beams 32 extending in opposite directions, and at least two corresponding sliders 33. The force-applying element 35 is an elastic element connecting the two sliders 33. The force-applying element 35 applies a radially inward force to the sliders 33. At the second rotational speed, the centrifugal force of the sliders 33 is greater than the force of the force-applying element 35. The force of the force-applying element 35 on the sliders 33 makes the sliders 33 more inclined to disengage from the gear ring 34. When the centrifugal force is greater than the force applied by the force-applying element 35, the sliders 33 move radially outward to engage with the gear ring 34. When the rotational speed decreases and the centrifugal force decreases, the force of the force-applying element 35 causes the sliders 33 to move radially inward to disengage from the gear ring 34. The force-applying element 35 ensures that the sliders 33 radially disengage from the gear ring 34 when the drive member 20 is running at a lower rotational speed, so that the clutch 30 is in a disengaged state, avoiding accidental swinging of the swing arm 40 when it is not needed, and improving the reliability of the clutch 30.

[0056] refer to Figure 4 As shown, the force-applying component 35 can be a spring, with its two ends connected to two sliders 33 respectively. This causes the two sliders 33 to tend to remain disengaged from the gear ring 34. When the rotational speed increases to a second rotational speed, the centrifugal force of the sliders 33 overcomes the elastic force to move radially outward and engage with the gear ring 34. When the rotational speed decreases, the sliders 33 move radially inward under the action of the elastic force and disengage from the gear ring 34. The cooperation between the two sliders 33 and the gear ring 34 can improve the stability of the engagement, and the sliders 33 can more stably drive the gear ring 34 to rotate.

[0057] Of course, in other embodiments, the force-applying element 35 can also be a magnetic element, and the corresponding slider 33 can be a corresponding magnetic element or be provided with a corresponding magnetic element. The force-applying element 35 can make the slider 33 move radially inward through magnetic force.

[0058] Additionally, the clutch 30 includes a cover plate 36 that covers the gear ring 34, protecting the internal structure of the gear ring 34. Furthermore, the clutch 30 may include a base portion, through which the rotating shaft 31 and the gear ring 34 are supported and rotatable relative to the base portion.

[0059] In some embodiments, the first transmission assembly includes a lifting structure, the cleaning component is connected to the lifting structure, and the driving component 20 drives the first transmission assembly to move. The driving component 20 has a first rotation direction and a second rotation direction. When the driving component rotates in the first rotation direction, the lifting structure causes the cleaning component to descend or rotate while cleaning. When the driving component 20 rotates in the second rotation direction, the lifting structure causes the cleaning component to ascend. The first and second rotation directions are opposite, meaning that when the driving component 20 rotates in different directions, the cleaning component can move to different positions, such as descending or ascending. Descending movement lowers the height of the cleaning component to contact the surface for cleaning, ascending movement allows the cleaning component to detach from the surface and retract, and rotational movement allows the cleaning component to clean the floor. Different rotation directions of the driving component 20 enable different movements of the cleaning component, eliminating the need for separate driving components for each movement, thus simplifying the structure, improving structural integration, and reducing costs.

[0060] As can be seen, the drive component 20 has two rotation speeds and two rotation directions, thus enabling operation in four different states, thereby controlling the operating states of the swing arm 40 and the cleaning component. Specifically, in the initial state, the cleaning component detaches from the ground, the swing arm 40 retracts into the machine body, the cleaning component is in the retracted position, the drive component 20 starts to operate at the first rotation speed and the first rotation direction, the swing arm 40 remains in a different position, and the cleaning component begins to descend. When it descends to its limit position, it begins to rotate forward around the second axis to clean the ground it contacts. At this time, if the drive component 20 switches to operating at the first rotation speed and the second rotation direction, the cleaning component can rise to detach from the ground, thus ending the cleaning process; or, if the drive component 20 switches to the second rotation speed and the first rotation direction, the cleaning component still rotates forward, and the swing arm 40 swings outward to the machine body 5. The cleaning component moves to the outside position, and then the drive component 20 reduces to the first rotation speed to stop the swing of the swing arm 40. Therefore, the ground outside the machine body 50 can be cleaned by the cleaning component. Then, the drive component 20 runs at the second rotation speed and the second rotation direction, and the swing arm 40 retracts and swings back into the machine body 50, so that the swing arm 40 returns to the machine body 50. At the same time, the cleaning component rises to the limit position to detach from the ground, so as to end the cleaning and return to the initial state. If it is necessary to clean the ground under the machine body 50, the drive component 20 can be made to run at the first rotation speed and the first rotation direction again, so that the cleaning component descends and rotates in the forward direction to clean the ground it contacts.

[0061] In some embodiments, the first transmission assembly further includes a second transmission gear 43 and a lifting structure. One axial end of the second transmission gear 43 has a recessed cavity. The lifting structure is drively connected to the second transmission gear 43 and is used for detachably connecting the cleaning component. The first end of the lifting structure is located within the recessed cavity. Additionally, a first transmission gear 42 is coaxially arranged with the swing gear 41, and the second transmission gear 43 is drively connected to the first transmission gear 42 via at least one transmission component.

[0062] The central axis of the swing gear 41 is also the central axis of the swing motion of the swing arm 40. When the first transmission gear 42 is coaxially arranged with the swing gear 41, the central axis of the first transmission gear 42 will not move relative to the base 10 when the swing arm 40 swings. Therefore, the transmission connection between the first transmission gear 42 and the drive component 20 can be better realized. The transmission between the two can be achieved through gears, transmission chains, belts, etc. The second transmission gear 43 can be transmitted to the first transmission gear 42 through gears, chains, belts, etc. The lifting structure can be connected to the cleaning component. The lifting structure receives the power provided by the second transmission gear 43 to drive the cleaning component to move, including lifting and rotating. (Refer to...) Figure 5As shown, a recess is formed on the lower side of the second transmission gear 43, which can accommodate part of the lifting structure. Therefore, the overall axial dimension of the second transmission gear 43 and the lifting structure can be reduced, decreasing the space occupied by the swing arm 40. This facilitates the overall spatial design of the cleaning equipment, such as reducing the overall thickness of the cleaning equipment or allowing other structures to be installed on the upper side of the swing arm 40. During the use of the cleaning equipment, the central axis of the second transmission gear 43 extends vertically. Since the lifting structure is partially accommodated in the recess of the second transmission gear 43, the vertical dimension can be reduced.

[0063] In some embodiments, the lifting structure includes a first bushing 44 coaxially connected to the second transmission gear 43 and a second bushing 45 coaxially sleeved on the first bushing 44. The first bushing 44 and the second bushing 45 are threaded together. When the driving member drives the second transmission gear 43 to rotate in the forward direction, the second bushing 45 can move axially from the upper limit position to the lower limit position. At the lower limit position, the first bushing 44 drives the second bushing 45 to rotate in the forward direction so that the cleaning member rotates for cleaning. When the driving member drives the second transmission gear 43 to rotate in the reverse direction, the second bushing 45 can move axially from the lower limit position to the upper limit position to lift the cleaning member. The first bushing 44 can be coaxially connected to the second transmission gear 43 via a connecting shaft 47. The second transmission gear 43 can drive the first bushing 44 to rotate synchronously, including forward and reverse rotation. Of course, forward (counterclockwise) and reverse (clockwise) are relative concepts and correspond to the first and second rotation directions of the driving member, respectively. The second bushing 45 is fitted onto the first bushing 44, and the two are threaded together. Therefore, when the first bushing 44 rotates in the forward direction, the second bushing 45, located at the upper limit position, will not rotate synchronously. Instead, it will be pushed downward by the first bushing 44. After reaching the lower limit position, under the action of the limiting component (the stop structure located in the threaded groove) on the first bushing 44 or the second bushing 45, the second bushing 45 cannot continue to descend but will rotate synchronously with the first bushing 44, thereby driving the cleaning component to rotate synchronously to achieve the cleaning action on the ground. When the first bushing 44 rotates in the reverse direction, the second bushing 45, located at the lower limit position, will not rotate synchronously. Instead, it will be pushed upward by the first bushing 44. When it reaches the upper limit position, the cleaning component is in a lifted state detached from the ground, or the second bushing 45 continues to move axially upward and separates from the cleaning component, thus achieving the disassembly of the cleaning component. As can be seen, by driving the first bushing 44 to rotate in the forward or reverse direction, the second bushing 45 can be lowered or raised. Upon reaching its lower limit position, the second bushing 45 can rotate, correspondingly enabling the cleaning component on the second bushing 45 to rise, fall, and rotate. Upon reaching its upper limit position, the cleaning component is either in a raised state or separated from and detached from the second bushing 45. This structural design allows for the lifting and rotation of the cleaning component simply by changing the direction of the motor. Therefore, it eliminates the need for multiple motors to achieve different movements of the cleaning component, reducing both cost and space requirements.

[0064] In some embodiments, the swing arm 40 is rotatable relative to the base 10 about a first axis to allow the cleaning component to have an inward retracted position and an outward swing position. The cleaning component is also rotatable relative to the swing arm 40 about a second axis to allow the cleaning component to perform rotational cleaning. When the cleaning component is in the inward retracted position, the first axis is positioned near the outer edge of the body 50 relative to the second axis in the width direction. The first and second axes are located at opposite ends of the swing arm 40. When the cleaning component is in the inward retracted position, the first axis can be located near the outer edge of the body 50 in the width direction, and the second axis is located inside the body 50. When the swing arm 40 swings to allow the cleaning component to reach the outward swing position, the second axis is located outside the body 50. The first axis being positioned near the edge of the body 50 allows full utilization of the length of the swing arm 40, increasing the distance between the cleaning component and the body 50 in the outward swing position, thereby expanding its cleaning range. It is understood that the swing arm 40 can position the cleaning component anywhere between the outward swing position and the inward retracted position.

[0065] In some embodiments, the second bushing 45 is provided with a magnetic suction member 46, and the cleaning member is connected to the second bushing 45 via the magnetic suction member. The cleaning member may be provided with a magnetic suction structure that cooperates with the magnetic suction member 46, so as to detachably install the cleaning member onto the second bushing 45. The cleaning member is connected to the second bushing 45 by magnetic attraction, which allows for quick installation and removal of the cleaning member without the aid of other tools, improving the convenience of installation and removal.

[0066] The cleaning components can be brushes, cloths, etc., which can be driven to rise, fall and rotate, and can be moved to a narrow space for cleaning under the swing action of the swing arm 40.

[0067] It is understood that the base 10 can be a detachable housing shape, and the clutch 30 and the transmission components for the drive unit 20, the clutch 30, and the first transmission assembly can be housed in the base 10; the swing arm housing 48 can also be detachable, and most of the structure of the first transmission assembly can be housed in the swing arm housing 48.
