[0085] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0086] In response to the problem that the cleaning body 20 of the existing cleaning equipment cannot be cleaned close to the edge, the first embodiment of the present application provides a cleaning device, please refer to Figures 1 to 3, the cleaning device includes a main body 10 and a cleaning mechanism. The main body is provided with an opening and a receiving cavity. The cleaning mechanism is arranged at the bottom of the main body 10, and the cleaning mechanism includes a cleaning body 20, a bracket 30 and a first drive assembly 40. The cleaning body 20 is connected to the bracket 30, and the cleaning body 20 can move with the bracket 30 to a first position and a second position. The first position is a position where the cleaning body 20 at least partially extends from the opening to the outer peripheral edge of the main body 10, and the second position is a position where the cleaning body 20 moves with the bracket 30 to retract into the receiving cavity. The first drive assembly 40 is connected to the bracket 30 to drive the cleaning body 20 to move back and forth between the first position and the second position. Figure 1 is a structural schematic diagram of the cleaning device when the cleaning body 20 extends out of the first position of the outer peripheral edge of the main body 10.

[0087] When the area to be cleaned is a corner, the cleaning body 20 of the cleaning device will move with the bracket 30 under the drive of the first drive assembly 40 to extend to the first position of the outer peripheral edge of the body 10 to clean the corner area between the wall and the body 10, ensuring that the corner area is cleaned in place and avoiding the phenomenon that there is a cleaning blind spot in the corner area after cleaning. Secondly, during the process of the cleaning body 20 moving back and forth between the first position and the second position with the bracket 30, the cleaning body 20 will have poor stability during the movement due to factors such as its own weight, grinding loss, and bumps, thereby affecting the cleaning and movement effect. In this regard, the cleaning mechanism provided in this embodiment also includes a support assembly 50, which is connected to the bracket 30 and at least partially penetrates the cleaning body 20 to support the cleaning body 20, so as to improve the stability of the cleaning body 20 during the movement, thereby improving the cleaning effect and the stability of the first drive assembly 40 driving the bracket 30.

[0088] Along the moving direction of the cleaning body 20, a receiving cavity can be set through the bottom of the body 10 to install and accommodate the cleaning mechanism, and enable the first driving component 40 of the cleaning mechanism to drive the bracket 30 to drive the cleaning body 20 to move back and forth between the first position and the second position.

[0089] As can be seen, the cleaning device provided in this embodiment includes a body 10 and a cleaning mechanism, the cleaning mechanism is arranged at the bottom of the body 10, the cleaning body 20 of the cleaning mechanism is connected to the bracket 30, the cleaning body 20 has a first position in which it moves with the bracket 30 to extend out of the outer edge of the body 10, and a second position in which it moves with the bracket 30 to retract to the inner bottom of the body 10, and the first driving assembly 40 of the cleaning mechanism is connected to the bracket 30 to drive the cleaning body 20 to move back and forth between the first position and the second position. Among them, when the cleaning body 20 is in the first position, the cleaning body 20 can clean the corners and other corners close to the edge, reducing the blind spots and dead angles in the corners, improving the cleaning rate, achieving an ideal cleaning effect, and providing a good user experience. Secondly, the support assembly 50 of the cleaning mechanism is connected to the bracket 30, and the support assembly 50 is at least partially inserted into the cleaning body 20 to support the cleaning body 20, thereby improving the stability of the cleaning body 20 during movement.

[0090] Among them, the first drive assembly 40 in this embodiment includes a first drive member 41 and a transmission member. The first drive member 41 is installed in the body 10. The transmission member is arranged between the bracket 30 and the first drive member 41. The transmission member drives the bracket 30 to move under the drive of the first drive member 41, so that the bracket 30 can drive the cleaning body 20 to move back and forth between the first position and the second position. When it is necessary to clean the corner position close to the edge, the first drive member 41 drives the bracket 30 to drive the cleaning body 20 to move to the first position, so as to clean the corner close to the edge at the first position, reduce the blind spot of the corner cleaning, and improve the cleaning rate. When there is no corner in the area to be cleaned, the first drive member 41 drives the bracket 30 to drive the cleaning body 20 to move to the second position, and clean the area to be cleaned according to the predetermined cleaning route.

[0091] As shown in Figures 2 and 3, the transmission component in this embodiment may include a gear 42 and a rack 43. Gear 42 is connected to the first drive member 41 and is rotatable in its own circumferential direction when driven by the first drive member 41. Rack 43 is mounted on the bracket 30 and meshes with gear 42. Rack 43 extends along a first direction, so that when gear 42 and rack 43 are meshed, rack 43 can move a certain distance relative to gear 42 in the first direction, thereby ensuring that the bracket 30 can drive the cleaning body 20 between the first and second positions in the first direction. The first direction is the direction in which the bracket 30 drives the cleaning body 20 back and forth between the first and second positions, i.e., the direction indicated by arrow X in Figure 2. The first drive member 41 drives gear 42 to rotate, and rack 43 drives the bracket 30 back and forth in the first direction relative to gear 42. This allows the bracket 30 to drive the cleaning body 20 back and forth between the first and second positions. This allows the cleaning body 20 to clean close to corners and other edges when in the first position, eliminating blind spots and improving the user experience. Furthermore, the use of the meshing gear 42 and rack 43 as transmission components allows for efficient and convenient assembly, occupies a small space, and is suitable for installation in a cleaning device body 10 with limited space. The first drive member 41 can be a motor, the shaft of which is coaxially connected to the gear 42 to drive the gear 42 to rotate. During the rotation of the gear 42, the rack 43 meshing with the gear 42 can move relative to the body 10, thereby driving the bracket 30 to move in the first direction.

[0092] In this embodiment, in order to improve the safety and reliability of the engagement between the gear 42 and the rack 43, the first drive assembly 40 may further include a protective cover, which is covered on the gear 42. A cavity for the rack 43 to pass through is provided on the side of the protective cover close to the rack 43, thereby preventing contaminants from entering between the gear 42 and the rack 43 and interfering with the transmission between the two, thereby improving the working stability of the transmission components.

[0093] As shown in FIG4 , the bracket 30 in this embodiment includes a bracket body 31, a first mounting portion 32, and a second mounting portion 33. A first drive assembly 40 is connected to the bracket body 31. The first mounting portion 32 is disposed at one end of the bracket body 31 along a first direction. The second mounting portion 33 is disposed at the other end of the bracket body 31 along the first direction, and a mounting slot is formed between the second mounting portion 33 and the first mounting portion 32. The cleaning body 20 is detachably connected to the mounting slot via a support assembly 50. When the cleaning body 20 needs to be replaced or repaired, the support assembly 50 is detached from the mounting slot, allowing the cleaning body 20 to be removed from the mounting slot, thereby conveniently performing replacement or maintenance operations on the cleaning body 20. The length of the support assembly 50 along the first direction can be determined based on the length of the cleaning body 20 along the first direction to ensure that the support assembly 50 can stably support the cleaning body 20. In some embodiments, support assemblies 50 can be provided on opposite sides of the cleaning body 20 along the first direction to support the cleaning body 20, thereby improving the stability of the cleaning body 20 during movement.

[0094] The cleaning body 20 in this embodiment includes a second drive assembly and a roller 21. The second drive assembly is connected to the first mounting portion 32 and is located within the mounting groove. The roller 21 is mounted on the second drive assembly and can rotate along its own circumferential direction under the drive of the second drive assembly. The outer circumference of the roller 21 is covered with a cleaning member, which typically includes a mop, cleaning brush, etc. The roller 21 is driven by the second drive assembly to rotate and clean the area to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the cleaning device when cleaning along the edge.

[0095] Specifically, as shown in Figure 3, a second drive assembly is provided at the end of the roller 21 away from the support assembly 50. The second drive assembly is connected to the first mounting portion 32 and is located in the mounting groove. The roller 21 is sleeved on the second drive assembly and can rotate along its own circumferential direction under the drive of the second drive assembly. Specifically, the second drive assembly includes a disassembly portion 91, a bearing seat 92, a second bearing 93, a second drive member 94, and a connector 95. The disassembly portion 91 is connected to the first mounting portion 32. The second drive member 94 is connected to the end of the disassembly portion 91 away from the first mounting portion 32 via the bearing seat 92. The second bearing 93 is disposed on the bearing seat 92, and the inner circumferential surface of the second bearing 93 is connected to the bearing seat 92. The connector 95 is located on the side of the second drive member 94 away from the second bearing 93 and is connected to the second drive member 94. The connector 95 rotates along its own circumferential direction under the drive of the second drive member 94. The connector 95 is removably inserted into the drum 21 to drive the drum 21 to rotate along its own axis. During the rotation process, the drum 21 drives a mop or other cleaning device to clean the floor. The side of the drum 21 away from the support assembly 50 is mounted on the second bearing 93. This drives the drum 21 to rotate through the connector 95 and the second bearing 93, while supporting the side of the drum 21 away from the support assembly 50. Therefore, this embodiment supports the drum 21 through the support assembly 50, the second bearing 93, and the connector 95, further improving the stability of the drum 21 during rotation and movement. The second driving member 94 can be a motor, and the motor's rotating shaft is connected to the connector 95 to drive the connector 95 to drive the drum 21 to rotate.

[0096] Among them, the support assembly 50 includes a support component and a mounting component. The support component is at least partially inserted into the drum 21 to provide stable support for the drum 21 during rotation and / or movement. The mounting component is connected to the support component and can rotate relative to the support component along the circumference of the drum 21. The mounting component is detachably connected to the second mounting portion 33. During the process of the drum 21 rotating along its own circumference under the drive of the second drive assembly, since the support component is rotatable relative to the mounting component, the support component does not interfere with the rotational motion of the drum 21 while supporting the drum 21, thereby ensuring the stability of the drum 21 during rotation and movement. Secondly, since the mounting component is detachably connected to the second mounting portion 33, when it is necessary to replace or maintain the drum 21 and / or the cleaning component mounted on the drum 21, the mounting component is disassembled from the second mounting portion 33, thereby removing the drum 21 connected to the connector 95 of the second drive assembly and performing corresponding replacement or maintenance work. For example, a cleaning member with greater wear and tear can be removed from the drum 21 and a new cleaning member can be installed on the drum 21, or a new drum 21 can be replaced. When the replacement or maintenance is completed, the support member is at least partially inserted into the drum 21, and the drum 21 is installed on the connector 95 and the second bearing 93. The drum 21 is then connected to the second mounting portion 33 through the mounting member, and the drum 21 is stably mounted and supported in the mounting groove, which is convenient and efficient to operate.

[0097] Referring to Figures 5 to 9 , the support components of support assembly 50 include a connecting shaft 51 and a support body 52. ​​Connecting shaft 51 is coaxially disposed with drum 21. One end of connecting shaft 51 is connected to a mounting component and is rotatable relative to the mounting component. Support body 52 is connected to the other end of connecting shaft 51. Support body 52 is at least partially disposed within drum 21 to support drum 21 and enhance its stability during rotation and movement.

[0098] As shown in FIG6 , a first groove 521 is provided on a side of the support body 52 proximal to the mounting member. A connecting hole 522 is provided at the bottom of the first groove 521. The connecting shaft 51 is at least partially embedded in the connecting hole 522 along its axial direction. The mounting member is at least partially sleeved within the first groove 521 and rotatably connected to the connecting shaft 51 on a side thereof away from the connecting hole 522 along a first direction. Because the connecting shaft 51 is rotatable relative to the mounting member, the support body 52 connected to the connecting shaft 51 can rotate with the drum 21 during rotation, thereby preventing interference with the rotation of the drum 21 and improving the stability of the drum 21 during movement and / or rolling. Furthermore, because the mounting member is at least partially housed and rotatably connected to the first groove 521 of the support body 52 via the connecting shaft 51, the structure of the entire support assembly 50 is made more compact and reliable. Moreover, when the support body 52 is passed through the drum 21 and supports the drum 21, the installation component will not increase the distance between the drum 21 and the second installation portion 33 along the first direction, thereby achieving support for the drum 21 through the support assembly 50 while reducing the cleaning blind area, so that the cleaning parts on the drum 21 can be cleaned along the edge.

[0099] As shown in FIG9 , the surface of the connecting shaft 51 is provided with a knurled portion 511 , which abuts against the inner wall surface of the connecting hole 522 to enhance the secure connection between the connecting shaft 51 and the connecting hole 522 of the support body 52 and prevent the support body 52 from shaking relative to the connecting shaft 51 and affecting the support stability. The cleaning mechanism of this embodiment also includes a plug-in assembly. The support body 52 is detachably connected to the drum 21 via the plug-in assembly. Thus, when the support assembly 50 needs to be replaced or maintained, the support body 52 can be removed from the drum 21.

[0100] As shown in FIG5 , when the support body 52 is a columnar structure (e.g., a cylindrical structure) that matches the inner wall surface of the drum 21, the plug assembly provided in this embodiment includes a plug groove 523 and a plug protrusion 524. The plug groove 523 is provided on at least one of the outer circumferential surface of the support body 52 and the inner wall surface of the drum 21. The plug protrusion 524 is adapted to the plug groove 523 and is provided on at least one of the outer circumferential surface of the support body 52 and the inner wall surface of the drum 21. Thus, by plugging and mating the plug protrusion 524 with the plug groove 523, the support body 52 is removably inserted into the drum 21. This not only facilitates the installation and removal of the support assembly 50, but also increases the friction between the support body 52 and the drum 21, thereby ensuring that the support body 52 can rotate stably with the drum 21, ensuring the stability of the drum 21 during rotation and movement.

[0101] Specifically, the outer circumference of the support body 52 is provided with a plurality of insertion protrusions 524 and a plurality of insertion grooves 523 along its circumference, with each insertion groove 523 located between two adjacent insertion protrusions 524. The inner wall surface of the drum 21 is also provided with a plurality of insertion protrusions 524 and a plurality of insertion grooves 523 along its circumference, with each insertion groove 523 located between two adjacent insertion protrusions 524. Furthermore, a boss 525 may be provided at the bottom of the insertion grooves 523 on the outer circumference of the support body 52. ​​When the support body 52 and the drum 21 are plugged together, the boss 525 abuts against the insertion protrusions 524 in the drum 21, further enhancing the secure connection between the support body 52 and the drum 21. Specifically, the bosses 525 can be one or more strip-shaped bosses 525 disposed at the bottom of the insertion groove 523. Along the radial direction of the support body 52, the height of the strip-shaped bosses 525 protruding from the outer circumference of the support body 52 is less than the height of the insertion bosses 524 on the support body 52 protruding from the outer circumference of the support body 52. ​​Furthermore, in this embodiment, the bosses 525, which serve to enhance the secure connection between the support body 52 and the drum 21, are disposed on the outer circumference of the support body 52, facilitating fabrication.

[0102] As shown in Figure 7, a locking structure is provided on the bracket 30, and the mounting components of the support assembly 50 include a main body 53 and a buckle portion 54. The main body 53 is rotatably connected to the support component. The main body 53 is specifically rotatably connected to the connecting shaft 51 of the support component. The buckle portion 54 is movably provided on a side of the main body 53 close to the locking structure. The buckle portion 54 has a third position in which it is buckled with the locking structure and a fourth position in which it is separated from the locking structure. When it is necessary to remove the roller 21, it is only necessary to release the buckle relationship between the buckle portion 54 and the second mounting portion 33 to conveniently remove the roller 21 connected to the support assembly 50.

[0103] As shown in Figures 8 and 10, the locking structure includes a second groove 331, which is located on a side of the second mounting portion 33 near the snap-fit ​​portion 54. The snap-fit ​​portion 54 includes an elastic member 541 and a snap-fit ​​joint 542. One end of the elastic member 541, along the first direction, is connected to the main body 53. The snap-fit ​​joint 542 fits within the second groove 331 and connects to the end of the elastic member 541 away from the main body 53. The snap-fit ​​joint 542 has a third position, where it snaps into the second groove 331 under the elastic force of the elastic member 541, and a fourth position, where it is free from the second groove 331. When the snap-fit ​​joint 542 is in the third position, the support assembly 50 is snap-fitted to the second mounting portion 33 via the snap-fit ​​joint 542. To remove the drum 21, the elastic member 541 is compressed, causing the snap-fit ​​joint 542 to move to the fourth position, free from the second groove 331, under the action of the elastic member 541.

[0104] As shown in Figures 7, 8, and 10, to facilitate the snapping of the snap joint 542 into or out of the second groove 331 of the second mounting portion 33, the snap joint 54 in this embodiment further includes a connecting block 543. The connecting block 543 is connected to the end of the elastic member 541 away from the main body 53. The snap joint 542 is disposed on a side of the connecting block 543 away from the elastic member 541. Along a first direction, the projected outer contour of the connecting block 543 is at least partially offset from the projected outer contour of the second mounting portion 33. Thus, when the snap joint 542 is located in the second groove 331, the portion of the connecting block 543 offset from the second mounting portion 33 can be pressed, causing the elastic member 541 to elastically contract under the pressure exerted on the connecting block 543, thereby driving the snap joint 542 out of the second groove 331.

[0105] In other words, the operator only needs to press the connecting block 543 to remove the roller 21 from the bracket 30, which is efficient and convenient. When the roller 21 needs to be installed on the bracket 30, after connecting the roller 21 to the second drive assembly, the snap joint 542 of the support assembly 50 that is inserted into the roller 21 is pressed into the second groove 331, and abuts against the second groove 331 under the action of the elastic tensile force of the elastic member 541. The elastic member 541 in this embodiment is preferably a spring. Therefore, by pressing the connecting block 543 to compress the spring, the snap joint 542 is separated from the second groove 331, thereby achieving the disassembly of the roller 21. By utilizing the compression and extension force of the spring to adjust the distance between the connecting block 543 and the main body 53, the snap joint 542 is snapped into the second groove 331, and the installation of the roller 21 can be achieved.

[0106] As shown in Figures 7 and 10, at least two snap joints 542 may be provided on the connecting block 543. The at least two snap joints 542 are located on opposite sides of the connecting block 543 along a third direction (the third direction is the direction indicated by arrow Z in Figure 2). At least two second grooves 331 are provided on one end of the second mounting portion 33 near the connecting block 543. The at least two second grooves 331 are arranged in a one-to-one correspondence with the at least two snap joints 542. By snapping the at least two snap joints 542 into the at least two second grooves 331, the assembly stability between the support assembly 50 and the second mounting portion 33 is improved. In other embodiments, the second grooves 331 may be provided on one end of the connecting block 543 near the second mounting portion 33, and the snap joint 542 may be provided on one end of the second mounting portion 33 near the connecting block 543. The second grooves 331 may be separated from the snap joints 542 on the second mounting portion 33 by pressing the connecting block 543, thereby achieving disassembly of the drum 21. Therefore, the specific location of the snap joints 542 and the second grooves 331 is not limited in this embodiment.

[0107] An open groove 332 is provided at one end of the second mounting portion 33 along the second direction (the second direction is the direction indicated by the arrow Y in FIG2 ). Along the first direction, the projection of the connecting block 543 at least partially covers the outer contour of the projection of the open groove 332, that is, the connecting block 543 is at least partially located in the open groove 332. Thus, the snap joint 542 can be separated from the second groove 331 by pressing the portion of the connecting block 543 located in the open groove 332, thereby achieving the disassembly of the drum 21. A third groove 531 is provided on one side of the main body 53 close to the second mounting portion 33, and the connecting block 543 is connected to the third groove 531 by an elastic member 541, so that the assembly structure between the connecting block 543 and the main body 53 is more compact, safe and reliable, saving the installation space between the drum 21 and the second mounting portion 33, and ensuring that the cleaning parts on the drum 21 can be cleaned along the edge. At this time, at least part of the connecting block 543 and the snap joint 542 are offset in the third groove 531 along the first direction under the extension of the elastic member 541, so that the snap joint 542 can be snapped into the second groove 331, and at least part of the connecting block 543 can be located at the opening groove 332 to facilitate the pressing operation of the connecting block 543.

[0108] As shown in Figure 7, a protrusion 532 is provided on the side of the main body 53 of the mounting component proximal to the second mounting portion 33, and a retaining groove 333 is provided on the side of the second mounting portion 33 proximal to the main body 53. The retaining groove 333 is located on the side of the opening 332 proximal to the bracket body 31 along the second direction. The retaining groove 333 is connected to the opening 332, reducing the difficulty of machining the retaining groove 333. The protrusion 532 abuts within the retaining groove 333 to further enhance the assembly stability between the main body 53 and the second mounting portion 33 during rotation and movement of the drum 21, preventing the snap joint 542 from detaching from the second mounting portion 33 due to shaking of the main body 53 caused by the rotation, rolling, or movement of the drum 21. The protrusion 532 in this embodiment can also be provided on the side of the second mounting portion 33 proximal to the main body 53, while the retaining groove 333 is provided on the side of the main body 53 proximal to the second mounting portion 33. This is not a limitation of this embodiment.

[0109] As shown in Figures 8 to 10, the main body 53 of the mounting component includes a first mounting seat 533, a first bearing 534, and a second mounting seat 535. A first clearance hole 5331 is provided in the first mounting seat 533 along a first direction. The first bearing 534 is positioned within the first clearance hole 5331, with its outer circumference connected to the inner wall of the first clearance hole 5331. The connecting shaft 51 is at least partially disposed within the first clearance hole 5331 and connected to the inner circumference of the first bearing 534. The end of the connecting shaft 51, facing away from the first clearance hole 5331 along the first direction, is specifically connected to the connecting hole 522 in the support body 52. ​​The second mounting seat 535 is located between the first mounting seat 533 and the second mounting portion 33 of the bracket 30 and is detachably connected to the first mounting seat 533. A mounting clearance is provided between the second mounting seat 535 and the connecting shaft 51 to prevent the second mounting seat 535 from interfering with the rotation of the connecting shaft 51. The snap-fit ​​portion 54 is connected to a side of the second mounting seat 535 proximal to the second mounting portion 33 to snap together with the second mounting portion 33. In this embodiment, two first bearings 534 may be provided. These two first bearings 534 are disposed side by side along the first direction within the first avoidance hole 5331 and connected to the connecting shaft 51. The outer circumferences of the two first bearings 534 are connected to the inner wall of the first avoidance hole 5331, and their inner circumferences are connected to the connecting shaft 51, thereby improving the assembly strength and rotational reliability between the connecting shaft 51 and the first mounting seat 533.

[0110] Secondly, when the fastening portion 54 includes a connecting block 543, a second guide assembly is further provided between the main body 53 of this embodiment and the connecting block 543. The second guide assembly is used to guide the movement of the connecting block 543 along the first direction to prevent the connecting block 543 from shaking relative to the main body 53 due to deviation in the moving direction, thereby affecting the fastening and disassembly operations between the fastening joint 542 and the second groove 331.

[0111] Specifically, as shown in Figure 10, the second guide assembly in this embodiment includes a plurality of first guide posts 56 and a plurality of second guide posts 57. The first guide posts 56 can be specifically disposed on a side of the second mounting seat 535 close to the buckle portion 54. Specifically, the third groove 531 of the main body 53 is disposed on a side of the second mounting seat 535 close to the second mounting portion 33. The bottom of the third groove 531 is provided with a plurality of first guide posts 56 spaced apart along the circumference of the drum 21. A first guide hole is provided in the first guide post 56, and a guide rod is provided in the first guide hole. The outer diameter of the guide rod is smaller than that of the first guide hole, and one end of the guide rod can be removably locked in the first guide hole by a locking member such as a screw. Multiple second guide posts 57 are positioned on the connecting block 543, corresponding one-to-one with the first guide holes. The outer diameter of each second guide post 57 matches the inner diameter of the first guide hole. A second guide hole is provided within each second guide post 57, and the inner diameter of the second guide hole matches the outer diameter of the guide rod. When the second guide post 57 is inserted into the first guide hole, the second guide hole and the guide rod are engaged. During the process of pressing or stretching the connecting block 543, the second guide post 57 can be inserted into the guide rod of the first guide hole and reciprocated relative to the guide rod in a first direction. This ensures that the connecting block 543 does not wobble relative to the second mounting base 535 during the pressing process, thereby reducing the difficulty of engaging and disassembling the snap joint 542 from the second groove 331. Specifically, at least two second guide posts 57 on the connecting block 543 are respectively connected to the side of the at least two snap joints 542 away from the second mounting portion 33, further improving the accuracy of the snap joints 542 engaging or disengaging with the second groove 331 under the action of the elastic member 541. This prevents the buckle joint 542 from shaking along with the connecting block 543 and making it difficult to buckle into the second groove 331 or difficult to separate from the second groove 331 .

[0112] Furthermore, because both the first guide post 56 and the second guide post 57 are located within the third groove 531, the mounting structure is more compact and easier to assemble. Furthermore, the installation distance between the drum 21 and the second mounting portion 33 is not increased, ensuring that the cleaning member on the drum 21 can perform edge cleaning. Therefore, in this embodiment, the first guide post 56 and the second guide post 57 guide the connecting block 543, ensuring that the snap joint 542 can stably and accurately snap into or out of the second groove 331, while also ensuring that the cleaning member mounted on the drum 21 can perform edge cleaning.

[0113] The support body 52 is provided with a second relief hole 526. In this embodiment, the main body 53 further includes a connecting protrusion 536 and a connecting post 537. The connecting protrusion 536 is disposed on a side of the first mounting seat 533 near the second mounting seat 535. A third relief hole 361 is disposed within the connecting protrusion 536. The third relief hole 361 extends through the first mounting seat 533 in the first direction and communicates with the second relief hole 526. A connecting post 537 is disposed on a side of the second mounting seat 535 near the first mounting seat 533. The connecting post 537 passes through the third relief hole 361 and is connected to the first mounting seat 533 via a locking member. When the support body 52 and the first mounting seat 533 are assembled on the connecting shaft 51, the locking member can be placed along the second relief hole 526 onto the third relief hole 361 to securely connect the connecting post 537 to the first mounting seat 533, thereby improving assembly efficiency and convenience between the second mounting seat 535 and the first mounting seat 533. Specifically, the second avoidance hole 526 is provided through one end of the support body 52 away from the first mounting seat 533 along the first direction. If there are multiple second avoidance holes 526, they can be provided around the outer periphery of the connecting hole 522 along the circumference of the support body 52. ​​Since the support body 52 can rotate relative to the first mounting seat 533 along with the connecting shaft 51 driven by the roller 21, whether there is one or more second avoidance holes 526, the support body 52 can be rotated to align and connect any second avoidance hole 526 with the third avoidance hole 361. The locking member can then be placed along the second avoidance hole 526 to the third avoidance hole 361 to securely connect the connecting post 537 to the first mounting seat 533.

[0114] As shown in FIG10 , to further secure and improve the connection between the first mounting base 533 and the second mounting base 535, a plurality of connecting protrusions 536 can be provided on the first mounting base 533, and a plurality of connecting posts 537 can be correspondingly provided on the second mounting base 535. In this case, the plurality of second avoidance holes 526 provided on the support body 52 can be rotated to correspond one-to-one with the plurality of third avoidance holes 361 within the connecting protrusions 536, thereby simultaneously connecting the first mounting base 533 and the second mounting base 535 together via the plurality of locking members, further improving the assembly efficiency between the first mounting base 533 and the second mounting base 535. The locking member in this embodiment can include at least one of a screw, a bolt, and a stud.

[0115] The support assembly 50 in this embodiment further includes a stopper, which is disposed on the connecting shaft 51 and located on a side of the first bearing 534 close to the second mounting seat 535. The stopper is used to retain the first bearing 534 on the connecting shaft 51 to prevent the first bearing 534 from falling off the connecting shaft 51. The stopper may specifically include a snap ring 55, which is sleeved on the connecting shaft 51 to retain the first bearing 534 on the connecting shaft 51 to prevent the first bearing 534 from falling off the connecting shaft 51.

[0116] The cleaning mechanism in this embodiment also includes a flexible protective cover, which covers the end of the support assembly 50 away from the cleaning body 20 and the end of the bracket 30 extending from the outer edge of the body 10. The flexible protective cover is used to prevent the support assembly 50 and / or the bracket 30 from colliding with furniture, walls, etc. during the cleaning process of the cleaning body 20, and to prevent the support assembly 50 and / or the bracket 30 from damaging furniture, walls, etc. or being damaged by furniture or walls. Specifically, when the support assembly 50 moves with the bracket 30 to the first position extending from the outer edge of the body 10, the end of the second mounting seat 535 of the support assembly 50 away from the drum 21 is located at the outer edge of the body 10, and the second mounting portion 33 of the bracket 30 is also located at the outer edge of the body 10. In order to prevent the second mounting seat 535 and the second mounting portion 33 from colliding with furniture, walls, etc. and causing damage to each other, the flexible protective cover in this embodiment specifically includes a first protective cover and a second protective cover. After the buckle joint 542 is buckled with the second mounting portion 33, the portion of the second mounting seat 535 offset from the second mounting portion 33 abuts the second mounting portion 33. The first protective cover can cover the portion of the second mounting seat 535 offset from the second mounting portion 33, and the second protective cover covers the second mounting portion 33. The second protective cover includes an integrally formed first protective portion and a second protective portion. The first protective portion covers the second mounting portion 33, and the second protective portion covers the side of the bracket body 31 away from the drum 21 along the third direction. The second protective portion prevents the bracket 30 from colliding with furniture.

[0117] In this embodiment, both the first mounting portion 32 and the second mounting portion 33 are plate-like structures, ensuring that the cleaning member mounted on the drum 21 can clean the edges and corners. Furthermore, the bracket body 31 is a curved plate-like structure that conforms to the outer surface of the drum 21 and covers the drum 21, thereby enhancing the structural strength of the entire cleaning mechanism.

[0118] In order to improve the stability of the cleaning body 20 during the movement of the bracket 30, the cleaning device provided in this embodiment also includes a first guide assembly. As shown in Figures 2 and 3, the first guide assembly includes a slider 70 and a guide rail 71, and the slider 70 is installed in the body 10. The guide rail 71 is installed on the bracket body 31 of the bracket 30, and the length of the guide rail 71 extends along the first direction. The guide rail 71 is connected to the slider 70 and can slide relative to the slider 70 along the bracket 30 along the first direction. This embodiment guides the cleaning body 20 to move smoothly along the first direction with the bracket 30 through the sliding fit between the slider 70 and the guide rail 71. Of course, in this embodiment, the slider 70 can also be installed on the bracket 30, and the guide rail 71 can be installed in the body 10. In this regard, this embodiment does not make the only limitation.

[0119] Furthermore, since cleaning is complete or obstacles need to be overcome, the cleaning body 20 needs to be lifted in the second direction away from the surface to be cleaned. To this end, when the slider 70 is mounted on the body 10, the slider 70 can be connected to a third drive assembly via a pull cord. The third drive assembly is used to drive the pull cord to raise and lower the cleaning body 20 on the bracket 30 in the second direction, thereby moving the cleaning body 20 away from or closer to the surface to be cleaned. To facilitate the connection between the pull cord and the slider 70, the pull cord in this embodiment is provided with an abutment portion. The slider 70 is provided with an abutment hole, and a notch is provided on one side of the abutment hole. The dimensions of the abutment hole and the notch are larger than the dimensions of the pull cord and smaller than the dimensions of the abutment portion. After the pull cord is moved into the abutment hole along the notch, the third drive assembly tightens the pull cord so that the abutment portion abuts against the side of the abutment hole closest to the slide rail. This eliminates the need for a locking member to secure the pull cord and slider 70, resulting in convenient operation and a reliable connection. The abutment portion can be a sphere with a diameter larger than the diameter of the abutment hole.

[0120] As shown in FIG2 , the cleaning device provided in this embodiment further includes a stopper 80. The stopper 80 is installed within the body 10 and positioned between the guide rail 71 and the rack 43. Along a first direction, the projected outer contour of the stopper 80 is at least partially positioned within the projected outer contours of the guide rail 71 and the rack 43. When the motor of the first drive assembly 40 drives the bracket 30 to move the cleaning body 20 to the first position, the guide rail 71 abuts against the stopper 80, thereby confining the cleaning body 20 to the first position and preventing the bracket 30 from further movement and causing the cleaning body 20 to separate from the body 10. After the cleaning body 20 completes edge cleaning, the motor reverses and drives the rack 43 to move the bracket 30 to the second position. The rack 43 abuts against the stopper 80, thereby confining the cleaning body 20 to the second position.

[0121] In addition, as shown in FIG4 , a water supply channel 312 and a plurality of water spray outlets are provided within the bracket body 31. The water supply channel 312 is laid out within the bracket body 31 along a first direction. The water spray outlets are provided on a side of the bracket body 31 near the cleaning body 20 and are in communication with the water supply channel 312. At least one or more water spray outlets are disposed opposite at least the portion of the cleaning body 20 that extends outside the body 10. When water and / or cleaning liquid is introduced into the water supply channel 312, the water and / or cleaning liquid can be sprayed toward the cleaning body 20 through the water spray outlets, causing the cleaning body 20 to be soaked and self-cleaned to better clean the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency. Furthermore, because at least one or more water spray outlets are disposed opposite at least the portion of the cleaning body 20 that extends outside the body 10, when the cleaning body 20 is cleaning along the edge, the portion of the cleaning body 20 that extends outside the body 10 can also be soaked and self-cleaned, thereby achieving better cleaning effect and cleaning efficiency.

[0122] The water supply channel 312 of the bracket body 31 is covered with a cover plate 311. A connecting pipe to the clean water tank can be provided on the cover plate 311. The clean water tank is equipped with a water pump to supply liquid to the water supply channel 312, so that the liquid can be sprayed onto the cleaning elements of the cleaning body 20 through a water nozzle. The liquid can be clean water, cleaning liquid, or a mixture of clean water and cleaning liquid, so that the cleaning elements are kept properly moist, thereby improving the cleaning ability of the cleaning elements. The bracket body 31 is also connected to a wiper strip 34. The wiper strip 34 has an interference fit with the cleaning elements on the drum 21, so as to scrape away dirty water and garbage from the cleaning elements during the rotation of the drum 21.

[0123] The cleaning body 20 further includes a wiper strip 34 and a water receiving trough. The first end of the wiper strip 34 abuts against the drum 21. The water receiving trough is disposed on the body 10 and is located outside the receiving cavity. The second end of the wiper strip 34 extends into the water receiving trough, with a first gap formed between the sidewall of the water receiving trough near the wiper strip 34 and the wiper strip 34.

[0124] When the cleaning device is operating, the roller 21 rotates within the receiving chamber to clean dirt on the floor. The first end of the wiper strip 34 abuts against the roller 21 to scrape off dirt and dirty water from the roller 21 and collect the dirty water into the water receiving trough. The cleaning body 20 of this embodiment has a first gap between the sidewall of the water receiving trough near the wiper strip 34 and the wiper strip 34, so that there is a certain gap between the wiper strip 34 and the sidewall of the water receiving trough. This prevents friction between the wiper strip 34 and the sidewall of the water receiving trough when the roller 21 moves, which could ultimately damage the wiper strip 34 or the water receiving trough. In the initial state, the minimum width A of the first gap satisfies the relationship: 0.3mm≤A≤0.5mm.

[0125] The initial state refers to the state in which the cleaning device is not activated and the drum 21 is fully contained within the receiving chamber. In this state, the minimum spacing A between the sidewalls of the water receiving trough and the wiper strip 34 should satisfy the following relationship: 0.3mm ≤ A ≤ 0.5mm. When A satisfies this relationship, the spacing between the sidewalls of the water receiving trough and the wiper strip 34 is not excessive, thereby preventing the cleaning device from becoming bulky and causing low space utilization. Furthermore, when A is within the above range, the spacing between the sidewalls of the water receiving trough and the wiper strip 34 is moderate, preventing the wiper strip 34 from contacting the sidewalls of the water receiving trough during movement, leading to interference between the two. When A is less than 0.3mm, the gap between the wiper strip 34 and the sidewalls of the water receiving trough is too small, potentially causing the wiper strip 34 to shake and interfere with the sidewalls of the water receiving trough during operation. When A is greater than 0.5mm, the spacing between the sidewalls of the water receiving trough and the wiper strip 34 is excessive, increasing the overall size of the cleaning device and reducing space utilization. The value of A can be 0.3mm, 0.32mm, 0.34mm, 0.36mm, 0.38mm, 0.4mm, 0.42mm, 0.44mm, 0.46mm, 0.48mm and 0.5mm.

[0126] As shown in Figures 11 and 12, the cleaning body 20 also includes a wiper strip 34. One end of the wiper strip 34 is movably connected to the bracket 30, and the other end of the wiper strip 34 abuts against the drum 21. The cleaning device also includes an elastic component and a limiting component. The elastic component is arranged between the bracket 30 and the wiper strip 34, and the elastic component applies elastic force to the wiper strip 34 so that the wiper strip 34 has a tendency to move toward the drum 21. The limiting component is arranged between the bracket 30 and the wiper strip 34, and the limiting component is used to limit the maximum displacement of the wiper strip 34 toward the drum 21. The drum 21 includes a drum body and a roller mop. The roller mop is arranged on the outer periphery of the drum body. When the cleaning device is cleaning, one end of the wiper strip 34 abuts against the roller mop to scrape off stains and dirty water on the roller mop. When the other end of the wiper strip 34 wears, the elastic component installed between the bracket 30 and the wiper strip 34, initially compressed, exerts an elastic force on the wiper strip 34 to return to its uncompressed state. Furthermore, since one end of the wiper strip 34 is movably mounted on the bracket 30, the elastic force exerted by the elastic component on the wiper strip 34 allows the worn wiper strip 34 to rest against the roller mop. When the wiper strip 34 exerts significant pressure on the roller mop, the limiting component applies a force opposite to the elastic force exerted by the elastic component on the wiper strip 34, thereby reducing the pressure exerted by the wiper strip 34 on the roller mop and preventing the roller body and the roller mop from being stuck by the wiper strip 34.

[0127] The bracket 30 is provided with a fourth clearance hole 35. The limiting component includes a limiting member 343, which passes through the fourth clearance hole 35 and connects to the wiper strip 34. The limiting member 343 is movable relative to the axis of the fourth clearance hole 35 and abuts against the bracket 30, limiting the maximum displacement of the wiper strip 34 toward the drum 21. The limiting member 343 comprises a connecting section 3431 and a flange section 3432. The connecting section 3431 passes through the fourth clearance hole 35 and connects to the wiper strip 34. The flange section 3432 is connected to the end of the connecting section 3431 facing away from the wiper strip 34 and protrudes from the outer circumference of the connecting section 3431. A portion of the projected surface of the fourth clearance hole 35 lies within the projected surface of the flange section 3432. The spacing between the fourth clearance hole 35 and the flange section 3432 is no greater than 5 mm.

[0128] The bracket 30 is provided with a first rotating shaft 341 extending along the axis of the drum 21. The wiper strip 34 is rotatably mounted on the first rotating shaft 341. The elastic component includes a torsion spring 342, which is mounted on the first rotating shaft 341. The first end of the torsion spring 342 abuts against the bracket 30, while the second end of the torsion spring 342 abuts against the wiper strip 34, thereby causing the second end of the wiper strip 34 to move toward the drum 21.

[0129] As shown in Figure 13, the cleaning body 20 also includes a wiper strip 34. A first end of the wiper strip 34 abuts against the drum 21, and a water outlet channel 36 is defined in the middle of the wiper strip 34. Along the first direction, the maximum width C of the water outlet channel 36 and the maximum width D of the wiper strip 34 satisfy the relationship: C < D.

[0130] Along the first direction, the maximum width D of the wiper strip 34 satisfies the relationship: 250 mm ≤ D ≤ 286 mm. Along the first direction, the maximum width C of the water outlet channel 36 satisfies the relationship: 93.45 mm ≤ C ≤ 106.8 mm. This embodiment limits the maximum width C of the water outlet channel 36 to less than the maximum width D of the wiper strip 34, thereby preventing the structural strength of the wiper strip 34 from being excessively weakened and damaging it due to external forces. Furthermore, limiting the maximum width C of the water outlet channel 36 to less than the maximum width D of the wiper strip 34 ensures that as the wiper strip 34 reciprocates in the first direction, wastewater and dirt flowing out of the water outlet channel 36 fall into the water receiving trough as much as possible. The provision of the water outlet channel 36 can reduce the structural strength of the wiper strip 34. When the maximum width C of the water outlet channel 36 is too large, for example, when C = D, the structural strength of the wiper strip 34 is too low, potentially causing damage to the wiper strip 34 due to external forces when the wiper strip 34 contacts the water receiving trough or other components of the cleaning device. On the other hand, in this embodiment, since the wiper strip 34 can reciprocate in the first direction, if the maximum width C of the water outlet channel 36 is too wide, dirt or sewage discharged from the water outlet channel 36 may not enter the water receiving trough when the wiper strip 34 moves in the first direction. In a preferred embodiment, C < (D / 2). When this relationship is satisfied, the width C of the water outlet channel 36 in the first direction is not too wide, thereby ensuring that the structural strength of the wiper strip 34 is not too low. When C≥(D / 2), the wiper strip 34 has too weak a structural strength under the action of the water outlet channel 36 . When the wiper strip 34 collides with the water receiving trough or other components of the cleaning device, the wiper strip 34 may be damaged.
