[0036] The present application provides a drum assembly.

[0037] Please refer to Figures 1 to 5 In an embodiment of the present application, the drum assembly 10 comprises a drum body 100 and a sliding member 200, the drum body 100 comprises a main body part 110 and a cleaning part 120, the main body part 110 has a receiving cavity 113, a first opening 114 and a second opening 115 which communicate with the receiving cavity 113, the first opening 114 is arranged on the circumferential side surface of the main body part 110, the second opening 115 is arranged on the end surface of one end of the main body part 110 in the axial direction and communicates with the first opening 114, the drum assembly 10 has a first working state and a second working state, in the first working state, the cleaning part 120 is accommodated in the first opening 114, in the second working state, the cleaning part 120 extends out corresponding to the second opening 115; the sliding member 200 is arranged in the receiving cavity 113 and movably connected with the cleaning part 120, the sliding member 200 can move along the axial direction of the main body part 110 and drive the cleaning part 120 to flip between the first opening 114 and the second opening 115, so as to switch the first working state and the second working state.

[0038] Specifically, the drum body 100 includes a main body part 110 and a cleaning part 120. The main body part 110 is a hollow structure, and has an accommodation cavity 113 inside for accommodating the sliding part 200 and other elements. A first opening 114 is located on the peripheral side surface (i.e. the outer cylindrical surface) of the main body part 110. In the first working state, the cleaning part 120 and the main body part 110 form a complete cylindrical drum structure, and the drum body 100 continuously rotates to clean the ground. At the same time, the cleaning assembly 40 inside the cleaning device continuously adds clean water to drain and clean the main body part 110 and the cleaning part 120. The dirty water is sucked away by the cleaning device and collected in the sewage collection tank 44 of the cleaning device, so as to realize automatic cleaning of the cleaning part 120, and the user does not need to manually replace and clean the cleaning part 120. A second opening 115 is located on the end surface of the axial end of the main body part 110 (towards the side of the cleaning device close to the wall surface), so as to facilitate the cleaning part 120 to be folded outwards and closely contact the skirting line area. The first opening 114 and the second opening 115 are in communication with each other, and form an "L"-shaped channel, so that the cleaning part 120 can complete the posture conversion from the horizontal direction to the vertical direction in the three-dimensional space.

[0039] The cleaning part 120 can be extended from different openings to adapt to different cleaning scenes. When the cleaning part 120 is accommodated at the first opening 114, the cleaning part 120 and the main body part 110 form a complete cylindrical drum structure, and perform the cleaning task on the ground. When the cleaning part 120 is folded and extended corresponding to the second opening 115, the cleaning part 120 faces the wall surface, and performs the cleaning task on the skirting line area. The sliding part 200 is installed in the accommodation cavity 113, and can be driven by a micro motor, an electromagnetic push rod or the like to move reciprocatingly along the axial direction of the main body part 110. The axial movement of the sliding part 200 drives the cleaning part 120 to complete the folding action through mechanical linkage (such as a connecting rod, a hinged structure or a flexible transmission), so as to switch the positions between the first opening 114 and the second opening 115, and thus switch the working states.

[0040] Please refer to Figure 2 and Figure 3 In the first working state, the cleaning part 120 is accommodated at the first opening 114 of the peripheral side surface of the main body part 110 and exposed outside the first opening 114. At this time, the overall shape of the drum assembly 10 is regular, which is suitable for regular ground cleaning, ensures that the drum assembly 10 is in full contact with the ground, and realizes stable and efficient ground cleaning. When the drum assembly 10 needs to switch the working state, the sliding part 200 starts to move along the axial direction, and drives the cleaning part 120 to perform the folding movement through the driving mode of pulling or pushing, so that the cleaning part 120 switches the positions corresponding to the first opening 114 and the second opening 115. Please refer to Figure 4 and Figure 5In the second working state, the cleaning part 120 is extended out of the second opening 115 of the end face through structural linkage, so that the outer side face can extend to a position close to the wall face, thereby directly contacting and cleaning the dust, hair and other dirt in the skirting line area.

[0041] The sliding part 200 is movably connected with the cleaning part 120 and can reciprocate along the axial direction of the main body part 110. When the sliding part 200 is axially displaced under the action of the driving mechanism, the cleaning part 120 is driven to overturn through mechanical linkage, so that it is turned from the position of being accommodated in the first opening 114 to the position of extending out of the second opening 115, so as to realize the switching of the roller assembly 10 from the first working state to the second working state. Conversely, the cleaning part 120 can also be reset from the position of extending out of the second opening 115 to the position of being accommodated in the first opening 114. In this way, the cleaning device can realize regular ground cleaning in the first working state and effective cleaning of the skirting line area in the second working state, thereby improving the cleaning ability of the cleaning device for the traditional difficult-to-reach skirting line area, effectively reducing the cleaning dead angle, improving the overall cleaning coverage and user experience. At the same time, this structure design of driving the cleaning part 120 to overturn and extend out through the sliding part 200 makes the roller assembly 10 be able to expand the cleaning range without increasing the overall volume, and flexibly adapt to the cleaning needs of different areas. Moreover, the sliding part 200 is built into the accommodating cavity 113 of the roller body 100, and the cleaning part 120 is accommodated in the first opening 114 in the first working state, without additional increase in the external volume of the cleaning device, without affecting the original body design and passability, thereby realizing the cleaning ability of the roller assembly 10 for the skirting line area and improving the space utilization rate of the roller assembly 10.

[0042] The technical scheme of the present application sets the first opening 114 and the second opening 115 on the roller body 100, so that the cleaning part 120 can be flipped between the position of being accommodated in the first opening 114 and the position of extending out of the second opening 115, so that the roller assembly 10 can be switched between the first working state and the second working state. In the first working state, the roller body 100 cooperates with the cleaning part 120 to realize efficient cleaning of the conventional ground area; at the same time, the main part 110 and the cleaning part 120 are cleaned by using the cleaning function of the cleaning equipment to add clean water, so as to realize automatic cleaning of the cleaning part 120; in the second working state, the cleaning part 120 extends out and acts on the skirting line area at the junction of the wall and the ground, effectively removing dust, hair and other pollutants accumulated in the area, thereby improving the cleaning ability of the cleaning equipment on the traditional difficult-to-reach corner area, expanding the overall cleaning range, improving the cleaning efficiency, and enhancing the adaptability of the cleaning equipment in complex home environment. At the same time, the user does not need to manually clean the skirting line, thereby reducing the cleaning burden of the user, saving time and energy, and thereby improving the user's experience.

[0043] In an embodiment, please refer to Figures 1 to 6 The cleaning part 120 is movably connected with the sliding piece 200 through the connecting rod assembly 300, and the connecting rod assembly 300 is used for converting the axial movement of the sliding piece 200 into the flipping movement of the cleaning part 120.

[0044] The connecting rod assembly 300 is used to movably connect the cleaning part 120 and the sliding piece 200, which can effectively convert the linear movement of the sliding piece 200 into the flipping movement of the cleaning part 120, so as to realize the smooth switching of the roller assembly 10 between different working states. Specifically, the cleaning part 120 is connected with the sliding piece 200 arranged in the accommodating cavity 113 of the roller body 100 through the connecting rod assembly 300. When the sliding piece 200 reciprocally moves along the axial direction of the main part 110 under the action of the driving mechanism such as a micro motor or an electromagnetic push rod, the linear displacement generated thereby pushes or pulls the cleaning part 120 to flip around the preset rotation fulcrum or hinge point, so that the cleaning part 120 is flipped from the position of being accommodated in the first opening 114 on the side surface of the main part 110 to the position of extending out of the second opening 115 on the axial end surface, or is flipped in the reverse direction. The connecting rod assembly 300 can be composed of a plurality of hingedly connected connecting rods, forming a transmission mechanism similar to a four-bar linkage or a rocker slider, ensuring smooth and reliable movement and rapid response.

[0045] The connecting rod assembly 300 has simple structure and high transmission efficiency, can complete complex action switching in limited space, and improves the integration and reliability of the drum assembly 10. The connecting rod transmission has good mechanical transmission characteristics, can realize stable overturning of the cleaning part 120 with small driving force, reduces the energy consumption and wear of the driving part, and prolongs the overall service life. After the cleaning part 120 completes the skirting line cleaning task, the cleaning part 120 can be reset to the first opening 114 in the complete drum form by means of the reverse transmission of the connecting rod assembly 300.

[0046] In other embodiments, the movable connection between the cleaning part 120 and the sliding part 200 can also be realized by a combination of a sliding groove and a pin structure.

[0047] In an embodiment, referring to Figure 3 , Figure 5 and Figure 6 , the drum assembly 10 further comprises a connecting shaft 400, two opposite guide sliding grooves 116 are arranged on the inner cavity wall of the accommodating cavity 113, and the two ends of the connecting shaft 400 are correspondingly inserted into the two guide sliding grooves 116; the connecting rod assembly 300 comprises a first connecting rod 310, a second connecting rod 320 and a third connecting rod 330, one end of the first connecting rod 310 is rotatably connected with the connecting shaft 400, and the other end is rotatably connected with the cleaning part 120; one end of the second connecting rod 320 is rotatably connected with the sliding part 200, and the other end is connected with the first connecting rod 310 through a cylindrical pair; the third connecting rod 330 is arranged on the other side of the sliding part 200 opposite to the second connecting rod 320, one end of the third connecting rod 330 is connected with the sliding part 200 through a cylindrical pair, and the other end is connected with the cleaning part 120 through a cylindrical pair.

[0048] The drum assembly 10 comprises a connecting shaft 400 arranged in the accommodating cavity 113 of the drum body 100, and the two ends of the connecting shaft 400 are correspondingly inserted into the two guide sliding grooves 116 arranged on the inner cavity wall of the accommodating cavity 113, forming a slidable guide matching structure. When the cleaning part 120 performs the overturning action, the connecting shaft 400 can slide along the guide sliding groove 116, which not only provides guidance and support for the movement of the cleaning part 120, but also limits the movement track to prevent deviation or jamming, ensuring smooth and reliable overturning process.

[0049] The connecting rod assembly 300 comprises a first connecting rod 310, a second connecting rod 320 and a third connecting rod 330, one end of the first connecting rod 310 is rotatably connected with the connecting shaft 400, and the other end is rotatably connected with the cleaning part 120, serving as the main driving arm for overturning of the cleaning part 120 towards the second opening 115. The connecting rod assembly 300 forms a multi-point linkage transmission mechanism by arranging a plurality of cylindrical pairs, and the connecting rod assembly 300 can adapt to the relative displacement change between the connecting points during movement, improving the stability and reliability of the mechanism movement.

[0050] The cylindrical pair refers to a composite motion pair allowing rotation and movement along the axis between two connecting components. The cylindrical pair can be realized by a structure, for example, the cylindrical pair includes a cylindrical pin shaft (or a sliding convex) arranged on one component and a long circular hole (or a sliding groove) arranged on another component, the pin shaft is slidably inserted into the long circular hole and can rotate around its own axis in the hole. This structure allows the component to slide along the length direction of the long circular hole and rotate around the axis of the pin shaft, thereby forming a cylindrical pair with two degrees of freedom.

[0051] In the embodiment, one end of the second connecting rod 320 is rotationally connected with the sliding piece 200, and the other end is connected with the first connecting rod 310 through a cylindrical pair, so as to realize the slidable and rotatable connection between the second connecting rod 320 and the first connecting rod 310. Specifically, the cylindrical pair includes the first sliding groove 311 and the first shaft body 710, the first connecting rod 310 is provided with the first sliding groove 311, the second connecting rod 320 is provided with the first shaft body 710 matched with the first sliding groove 710, the first shaft body 710 is inserted into the first sliding groove 311 and can slide and rotate. The third connecting rod 330 is arranged on the other side of the sliding piece 200, and the third connecting rod 330 has opposite first and second ends. The first end of the third connecting rod 330 is connected with the sliding piece 200 through a cylindrical pair, so as to realize the slidable and rotatable connection between the first end of the third connecting rod 330 and the cleaning part 120. Specifically, the cylindrical pair includes the second sliding groove 1231 and the second shaft body 720, the first end of the third connecting rod 330 is provided with the second shaft body 720, the cleaning part 120 is provided with the second sliding groove 1231 matched with the second shaft body 720, the second shaft body 720 is inserted into the second sliding groove 1231 and can slide and rotate. The other end of the third connecting rod 330 is connected with the cleaning part 120 through a cylindrical pair, so as to realize the slidable and rotatable connection between the second end of the third connecting rod 330 and the sliding piece 200. Specifically, the cylindrical pair includes the third sliding groove 331 and the third shaft body 730, the second end of the third connecting rod 330 is provided with the third sliding groove 331, the sliding piece 200 is provided with the third shaft body 730 matched with the third sliding groove 331, and the third shaft body 730 is inserted into the third sliding groove 331 and can slide and rotate. In the process of switching the third connecting rod 330 from the first working state to the second working state, the third connecting rod 330 plays a role in auxiliary support and balance of stress.

[0052] When the sliding member 200 moves in the axial direction of the main body 110 under the action of the driving member to the second opening 115, the sliding member 200 drives the first end of the second connecting rod 320 to move forward, and the other end of the second connecting rod 320 drives the first connecting rod 310 to move a distance and then starts to slide relative to the first connecting rod 310, so that the first connecting rod 310 rotates around the connecting shaft 400, thereby driving the cleaning part 120 to flip; the two ends of the connecting shaft 400 slide synchronously along the guide sliding groove 116 to adapt to the displacement requirement caused by the change of the angle of the connecting rod; at the same time, the third connecting rod 330 cooperates to form a stable three-point linkage mechanism, which jointly drives the cleaning part 120 to complete the flipping action from the first opening 114 to the second opening 115 and extends out of the second opening 115 to face the wall surface to enter the second working state. When the sliding member 200 moves reversely, the two ends of the third connecting rod 330 slide relative to the sliding member 200 and the cleaning part 120 respectively, and at the same time, the second connecting rod 320 pulls back the first connecting rod 310 to synchronize the reset, which jointly drives the cleaning part 120 to complete the flipping action from the second opening 115 to the first opening 114 and is re-stored in the first opening 114 to face the ground to enter the first working state. The drum restores the complete cylindrical structure and enters the normal ground cleaning mode.

[0053] Through the cooperation of the connecting shaft 400 and the guide sliding groove 116, a stable rotation fulcrum and movement guide are provided for the flipping of the cleaning part 120, the rigidity and movement precision of the structure are enhanced, and deformation or wear caused by unilateral stress is avoided. The linkage mechanism composed of three connecting rods realizes uniform distribution and multi-path transmission of force, which not only improves the stability and response speed of transmission, but also effectively reduces the stress concentration of a single connecting point and prolongs the service life of the component. After the cleaning part 120 completes the cleaning of the skirting line area and resets, it can be re-stored in the first opening 114 and restored to a complete cylindrical drum structure, without affecting the normal ground cleaning performance and passability of the cleaning equipment.

When the sliding member 200 moves along the axial direction of the drum main body 110, the second connecting rod 320 pushes the first shaft body 710 to slide in the first sliding groove 311, thereby driving the first connecting rod 310 to rotate around the connecting shaft 400. The inner side of the cleaning part 120 is provided with a first connecting part 123 extending along the length direction thereof, and the first connecting part 123 is provided with a second sliding groove 1231, and one end of the third connecting rod 330 is slidably connected to the second sliding groove 1231 through a second shaft body 720 (such as a pin shaft, a sliding pin or a convex shaft formed on the third connecting rod 330). The connection between the third connecting rod 330 and the cleaning part 120 has a certain degree of freedom, and during the overturning process of the cleaning part 120, the second shaft body 720 can slide in the second sliding groove 1231 to adapt to the change of the movement track of the cleaning part 120. The third connecting rod 330 is further provided with a third sliding groove 331 extending along the length direction thereof, and the third sliding groove 331 is located at the end away from the cleaning part 120. The sliding member 200 is slidably connected to the third sliding groove 331 through a third shaft body 730 (such as a pin shaft, a sliding pin or a convex shaft formed on the sliding member 200). When the sliding member 200 moves along the axial direction, the third shaft body 730 slides in the third sliding groove 331, drives the third connecting rod 330 to change the angle, and then cooperates with the first and second connecting rods 320 to drive the cleaning part 120 to complete the overturning action.

[0056] It is worth mentioning that after the cleaning part 120 is overturned from the first opening 114 to the second opening 115, the first connecting rod 310 remains stable under the joint action of the second connecting rod 320 and the connecting shaft 400, and the second connecting rod 320 also remains stable under the joint action of the first connecting rod 310 and the sliding member 200, so that the first connecting rod 310 and the second connecting rod 320 both remain stable in the position and pose, and jointly support the cleaning part 120 to be stably positioned at the position corresponding to the second opening 115. At the same time, the side edge of the sliding member 200 close to the second opening 115 abuts against the edge of the inner side of the cleaning part 120 to support the cleaning part 120, so that the overturned cleaning part 120 can be stably erected outside the end surface of the drum main body 100.

[0057] In an embodiment, please refer to Figure 3 、 Figure 5 and Figure 6The sliding member 200 comprises a sliding plate 210, one side of the sliding plate 210 is provided with a second connecting portion 220 for connecting the second connecting rod 320, and the opposite side is provided with a third connecting portion 230 for connecting the third connecting rod 330. The sliding plate 210 is provided with an avoiding gap 240 at one end close to the second opening 115, and the avoiding gap 240 is arranged corresponding to the first connecting portion 123 for avoiding the first connecting portion 123.

[0058] The sliding member 200 adopts a plate structure, one side of the sliding plate 210 is provided with a second connecting portion 220 for connecting the second connecting rod 320, and the opposite side is provided with a third connecting portion 230 for connecting the third connecting rod 330. The second connecting rod 320 and the third connecting rod 330 are connected to the sliding plate 210 from two sides thereof, which not only provides sufficient movement space for the first connecting rod 310, the second connecting rod 320 and the third connecting rod 330 to avoid mutual interference, but also makes the force on both sides more balanced, ensures smooth sliding of the sliding member 200 in the axial direction in the accommodating cavity 113, and improves the transmission accuracy and operation reliability. The sliding plate 210 is provided with an avoiding gap 240 at one end close to the second opening 115, and the avoiding gap 240 is arranged corresponding to the first connecting portion 123 inside the cleaning portion 120. When the cleaning portion 120 is driven to perform the overturning movement by the connecting rod assembly 300, the first connecting portion 123 will be displaced, and the avoiding gap 240 provides sufficient movement space for the first connecting portion 123 and the second sliding groove 1231 thereon to prevent structural interference or collision during relative movement.

[0059] In other embodiments, the sliding member 200 can also be in a block shape or a cylindrical shape.

[0060] In an embodiment, referring to Figure 1 , Figure 3 and Figure 5 , the guide sliding groove 116 comprises a first groove section 1161 and a second groove section 1162 connected in communication, the first groove section 1161 is arranged at one end of the second groove section 1162 away from the second opening 115 and extends in the axial direction of the main body portion 110, and the second groove section 1162 extends in the axial direction of the main body portion 110 and inclines towards the direction away from the first opening 114.

[0061] The guide sliding groove 116 is arranged on the inner cavity wall of the drum body 100 accommodating cavity 113, and is arranged in pairs opposite to each other, and is used to guide the sliding movement of the connecting shaft 400 at both ends. The guide sliding groove 116 includes a first groove section 1161 and a second groove section 1162 connected in communication, the first groove section 1161 is located at one end away from the second opening 115, and extends in the axial direction of the main body part 110, and provides stable axial guidance for the movement of the connecting shaft 400 in the initial stage; the second groove section 1162 extends from the end of the first groove section 1161, and extends in the axial direction of the main body part 110 and inclines in the direction away from the first opening 114, that is, the extension direction has a certain angle relative to the axis, forming a diagonal guide path, which cooperates with the connecting rod assembly 300 to realize the controllable overturning of the cleaning part 120, and enhances the coordination of the entire transmission system.

[0062] When the sliding part 200 moves in the axial direction under the action of the driving part, and drives the cleaning part 120 to overturn through the connecting rod assembly 300, the two ends of the connecting shaft 400 slide in the guide sliding groove 116. In the initial stage of switching from the first working state to the second working state, when the connecting shaft 400 moves linearly along the first groove section 1161, the first connecting rod 310 does not rotate around the connecting shaft 400, and the cleaning part 120 moves in the axial direction of the main body part 110 and in the direction of the second opening 115 under the drive of the first connecting rod 310. When the connecting shaft 400 moves to the connection between the first groove section 1161 and the second groove section 1162, the sliding part 200 continues to move in the axial direction, and after the connecting shaft 400 enters the second groove section 1162, the movement direction of the connecting shaft 400 changes due to the inclined extension of the second groove section 1162, the first connecting rod 310 rotates around the connecting shaft 400, and guides the cleaning part 120 to gradually overturn with the first connecting rod 310 as the radius, and finally the cleaning part 120 extends outwards from the second opening 115 on the end face of the main body part 110, so as to realize the overturning of the cleaning part 120 from the circumferential accommodation state to the axial extension state. At this time, the end of the sliding part 200 close to the second opening 115 abuts against the two side edges of the inner side face of the cleaning part 120, so as to provide at least two support points for the cleaning part 120, and under the joint support of the sliding part 200, the first connecting rod 310 and the second connecting rod 320, the cleaning part 120 can be stably arranged on the end face of the drum body 110.

[0063] The cleaning part 120 can be reversely moved to reset to the first opening 114 after the task is completed, and the complete cylindrical drum structure is restored, which does not affect the conventional ground cleaning operation of the cleaning equipment. During the resetting process, the connecting shaft 400 retreats along the second groove section 1162 to the first groove section 1161, the movement path is reversible, and the action is reliable.

[0064] In an embodiment, please refer to Figures 1 to 3In the first working state, the cross section of the cleaning part 120 cut by a plane perpendicular to the axial direction of the main body part 110 is an arc segment, the arc segment extends along the circumferential direction of the main body part 110, and is in close fit with the edge of the first opening 114.

[0065] The arc design of the cleaning part 120 enables the cleaning part 120 to smoothly transition with the outer circumferential surface of the drum body 100 in the accommodation state, and together form a complete and continuous drum structure without obvious steps or gaps, thereby ensuring the roundness and continuity of the outer surface of the drum. In the first working state, the complete drum structure formed by the cleaning part 120 and the main body part 110 can ensure that the drum body 100 and the cleaning part 120 are in full and uniform contact with the ground, effectively transmit the rolling pressure, improve the wiping and adsorption capacity of dust, particulate matter and liquid stains on the ground, and ensure the efficiency and consistency of ground cleaning. Moreover, the close fit design of the arc-shaped cleaning part 120 and the edge of the first opening 114 avoids the gap or protrusion problem commonly seen in traditional movable parts, prevents foreign matter such as hair and fine lines from being stuck in the moving gap, reduces the risk of entanglement, and improves the operation reliability. At the same time, this close fit design can also reduce vibration and noise during high-speed rotation, and improve the running stability of the cleaning equipment.

[0066] In an embodiment, referring to Figure 2 and Figure 3 , the main body part 110 includes a drum support 111 and a first cleaning layer 112 sleeved on the outer periphery of the drum support 111, and the cleaning part 120 includes a movable support 121 and a second cleaning layer 122 arranged on the outer surface of the movable support 121, the movable support 121 is movably connected with the sliding part 200, and in the first working state, the outer surfaces of the first cleaning layer 112 and the second cleaning layer 122 are flush.

[0067] The main body part 110 includes the drum support 111 located in the inner layer and the first cleaning layer 112 sleeved on the outer periphery thereof, wherein the drum support 111 serves as a structural support member, provides a containing cavity 113 and a mounting base, and the first cleaning layer 112 is arranged on the outer surface of the drum support 111 and is used to perform a conventional ground cleaning task, and the material thereof can be selected from materials such as velvet, silica gel strips or short pile hair, which have good dust collecting and wiping performance. The cleaning part 120 includes the movable support 121 and the second cleaning layer 122 arranged on the outer surface thereof, the movable support 121 serves as a bearing structure of the cleaning part 120, is movably connected with the sliding part 200 through the connecting rod assembly 300, and realizes a reversible mounting; and the second cleaning layer 122 is arranged on the outer surface of the movable support 121, and the material thereof can be the same as that of the first cleaning layer 112 or be adapted and optimized according to the skirting line cleaning requirement, so as to enhance the adsorption and scraping capacity of dust and hair on the bottom of the wall.

[0068] In the first working state, the cleaning part 120 is accommodated in the first opening 114 of the side surface of the main body part 110, at this time, the outer surfaces of the first cleaning layer 112 and the second cleaning layer 122 are flush with each other, and together form a complete cleaning surface which is continuous, smooth and without step difference, which ensures the roundness and continuity of the overall outer contour of the drum assembly 10, so that the drum is uniformly attached to the ground during rotation, avoiding the jumping, slipping or uneven cleaning phenomenon caused by the uneven surface, and improving the stability and efficiency of ground cleaning.

[0069] When the cleaning device returns to the base station, the drum assembly 10 as a whole can be flushed, and the first cleaning layer 112 and the second cleaning layer 122 are cleaned synchronously, and the sewage is sucked into the recycling, without the need for the user to manually disassemble and wash the second cleaning layer 122, greatly improving the convenience and hygiene level of use.

[0071] The drum assembly 10 comprises a fixed plate 500 arranged in the accommodating cavity 113, the fixed plate 500 is located on the side of the sliding part 200 away from the second opening 115, i.e. on the side of the second opening 115 close to the axial inner end of the drum body 100 and away from the end surface, and the fixed plate 500 serves as a support and installation base and can be firmly fixed inside the accommodating cavity 113 by welding, buckling or screws. One end of the guide shaft 600 is connected to the fixed plate 500 and extends along the axial direction of the main body part 110 towards the second opening 115, and the sliding part 200 is provided with a guide hole or a sliding sleeve and is movably sleeved on the guide shaft 600.

[0072] When the sliding part 200 moves along the axial direction of the main body part 110 towards or away from the second opening 115 under the drive of the driving part, it is always constrained and guided by the guide shaft 600. The guide shaft 600 and the fixed plate 500 together form a stable linear guide system, effectively limiting the radial deviation, swing or torsion of the sliding part 200 during movement, ensuring smooth sliding along the predetermined axial path, avoiding uneven stress or movement interference between the first connecting rod 310, the second connecting rod 320 and the third connecting rod 330 due to the unstable posture of the sliding part 200, thereby improving the response speed and repeated positioning accuracy of the overturning action of the cleaning part 120.

[0073] In other embodiments, one of the inner wall of the accommodating cavity 113 and the sliding member 200 is provided with a guide rail, and the other is provided with a guide groove, so as to guide the movement of the sliding member 200.

[0075] The roller assembly 10 further comprises a driving member (not shown in the figure), which can be a compact power device such as a micro motor, an electromagnetic push rod or a micro linear motor. The installation position of the driving member fully utilizes the internal space of the roller body 100 and does not affect the external structural layout and cleaning function. The driving shaft of the driving member penetrates through the through hole on the fixed plate 500 and is drivingly connected with the sliding member 200, so as to directly transmit the driving force to the sliding member 200 and push it to move along the axial direction of the main body 110 towards or away from the second opening 115.

[0076] The fixed plate 500 not only serves as the mounting base of the guide shaft 600, but also bears the support and positioning functions of the driving member, and simultaneously plays the roles of isolation and protection, so as to prevent external dust, liquid or hair from invading the area where the driving member is located and improve the sealing performance and operation reliability of the overall system. After the driving shaft penetrates through the fixed plate 500, it can be connected with the sliding member 200 through threaded transmission (such as a screw structure), push rod connection or linkage of connecting rods, so as to ensure efficient power transmission, rapid response and controllable action. When the cleaning device identifies that the skirting line area needs to be cleaned, the control system starts the driving member, the driving shaft is extended, and the sliding member 200 is driven to move along the guide shaft 600 towards the second opening 115. Through the coordinated linkage of the first connecting rod 310, the second connecting rod 320 and the third connecting rod 330, the cleaning part 120 is flipped around the connecting shaft 400, switches from the position of being accommodated in the first opening 114 to being extended outwards from the second opening 115, enters the second working state, and performs the cleaning task of the skirting line at the junction of the wall surface and the ground. After cleaning, the driving member reverses, the driving shaft is retracted, the sliding member 200 is reset, and the cleaning part 120 is flipped back and accommodated in the first opening 114 again, thereby restoring the first working state.
