[0072] In view of the problem that the cleaning body 20 of the existing cleaning equipment cannot be close to the edge for cleaning, the first embodiment of the utility model provides a cleaning device, see Figures 1 to 3 The cleaning device includes a body 10 and a cleaning mechanism. The cleaning mechanism is disposed at the bottom of the body 10, and includes a cleaning body 20, a bracket 30, a first driving assembly 40, and a supporting assembly 50. The cleaning body 20 is connected to the bracket 30, and the cleaning body 20 has a first position in which the cleaning body 20 moves with the bracket 30 to extend out of the outer peripheral edge of the body 10, and a second position in which the cleaning body 20 moves with the bracket 30 to retract to the inner bottom of the body 10, and the first driving assembly 40 is connected to the bracket 30 to drive the cleaning body 20 to reciprocate between the first position and the second position. Figure 1 It is a structural schematic diagram of the cleaning device when the cleaning body 20 is extended out of the first position of the outer peripheral edge of the body 10.

[0073] 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 driving assembly 40 to extend to the first position of the outer peripheral edge of the body 10, so as to clean the corner area between the wall and the body 10, to ensure that the corner area is cleaned in place, and to avoid the phenomenon that there is a 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 its own weight, grinding loss, bumps and other factors, thereby affecting the cleaning and movement effects. In this regard, the support assembly 50 provided in this embodiment is connected to the bracket 30 and is at least partially penetrated into 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 driving assembly 40 driving the bracket 30.

[0074] Along the moving direction of the cleaning body 20, a receiving groove may be provided through the bottom of the body 10 to install and receive the cleaning mechanism, and enable the first driving assembly 40 of the cleaning mechanism to drive the bracket 30 to drive the cleaning body 20 to reciprocate between the first position and the second position.

[0075] It can be seen that 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 that moves with the bracket 30 to extend out of the outer peripheral edge of the body 10, and moves with the bracket 30 to retract to the second position of the inner bottom of the body 10, and the first driving component 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, reduce the blind spots and dead angles in the corners, improve the cleaning rate, achieve an ideal cleaning effect, and provide a good user experience. Secondly, the support component 50 of the cleaning mechanism is connected to the bracket 30, and the support component 50 is at least partially inserted into the cleaning body 20 to support the cleaning body 20, so as to improve the stability of the cleaning body 20 during movement.

[0076] Among them, the first driving assembly 40 in this embodiment includes a first driving member 41 and a transmission member. The first driving member 41 is installed in the body 10. The transmission member is arranged between the bracket 30 and the first driving member 41, and the transmission member drives the bracket 30 to move under the drive of the first driving 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 driving 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 driving member 41 drives the bracket 30 to drive the cleaning body 20 to move to the second position, and cleans the area to be cleaned according to the predetermined cleaning route.

[0077] like Figure 2 and Figure 3 As shown, the transmission component in this embodiment may include a gear 42 and a rack 43. The gear 42 is connected to the first driving member 41 and can rotate along its own circumferential direction under the drive of the first driving member 41. The rack 43 is mounted on the bracket 30 and meshes with the gear 42, and the length of the rack 43 extends along the first direction, so that when the gear 42 and the rack 43 are meshed, the rack 43 can move a certain distance relative to the gear 42 along the first direction, thereby ensuring that the bracket 30 can drive the cleaning body 20 to move between the first position and the second position along the first direction. The first direction is the direction in which the bracket 30 drives the cleaning body 20 to reciprocate between the first position and the second position, that is, Figure 2 The direction indicated by the arrow X in the middle. The first driving member 41 drives the gear 42 to rotate, and the rack 43 drives the bracket 30 to reciprocate relative to the gear 42 along the first direction, so that the cleaning body 20 is driven to reciprocate between the first position and the second position by the bracket 30, so that when the cleaning body 20 is in the first position, the cleaning body 20 can clean the edge areas such as the corners, and there is no blind spot for cleaning, thereby improving the user experience. In addition, the gear 42 and the rack 43 that mesh with each other are used as transmission components, which are efficient and convenient to assemble, occupy a small space, and are suitable for the cleaning equipment body 10 with limited installation space. The first driving member 41 can be a motor, and the rotating shaft of the motor 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 along the first direction.

[0078] In this embodiment, in order to improve the safety and reliability of the meshing between the gear 42 and the rack 43, the first drive component 40 may also 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 therebetween, thereby improving the working stability of the transmission components.

[0079] like Figure 4 As shown, the bracket 30 in this embodiment includes a bracket body 31, a first mounting portion 32 and a second mounting portion 33. The first driving assembly 40 is connected to the bracket body 31. The first mounting portion 32 is arranged at one end of the bracket body 31 along the first direction. The second mounting portion 33 is arranged at the other end of the bracket body 31 along the first direction, and a mounting groove is formed between the second mounting portion 33 and the first mounting portion 32, and the cleaning body 20 is detachably connected to the mounting groove through the support assembly 50. When the cleaning body 20 needs to be replaced or the cleaning body 20 is maintained and repaired, the support assembly 50 is disassembled and separated from the mounting groove, so that the cleaning body 20 is removed from the mounting groove, so that the cleaning body 20 can be easily replaced or maintained and repaired. The length of the support assembly 50 along the first direction can be determined according to the length of the cleaning body 20 along the first direction, so as to ensure that the support assembly 50 can stably support the cleaning body 20. In some embodiments, the support assembly 50 can be arranged on both sides of the cleaning body 20 along the first direction to support the cleaning body 20, so as to improve the stability of the cleaning body 20 during the moving work process.

[0080] 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 in the mounting groove. The roller 21 is sleeved on the second drive assembly and can rotate along its own circumference under the drive of the second drive assembly. A cleaning member is sleeved on the outer circumference of the roller 21, and the cleaning member can generally include a mop, a cleaning brush, etc. The roller 21 drives the cleaning member to rotate and clean the area to be cleaned under the drive of the second drive assembly, so as to improve the cleaning efficiency and cleaning effect of the cleaning device when cleaning along the edge.

[0081] Specifically, Figure 3As shown, a second drive assembly is provided at one end of the drum 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, and the drum 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 and assembly portion 91, a bearing seat 92, a second bearing 93, a second drive member 94 and a connector 95. The disassembly and assembly portion 91 is connected to the first mounting portion 32, the second drive member 94 is connected to one end of the disassembly and assembly portion 91 away from the first mounting portion 32 through the bearing seat 92, the second bearing 93 is arranged 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, and the connector 95 rotates along its own circumferential direction under the drive of the second drive member 94. The connector 95 is detachably inserted into the drum 21 to drive the drum 21 to rotate along its own axial direction, and the drum 21 drives a mop or other cleaning member to clean the floor during the rotation process. The side of the drum 21 away from the support assembly 50 is sleeved on the second bearing 93, so that the drum 21 is driven to rotate through the connector 95 and the second bearing 93, and the side of the drum 21 away from the support assembly 50 is supported. Therefore, in this embodiment, the drum 21 is supported by the support assembly 50, the second bearing 93 and the connector 95, which further improves the stability of the drum 21 during rotation and movement. The second driving member 94 can be a motor, and the rotating shaft of the motor is connected to the connector 95 to drive the connector 95 to drive the drum 21 to rotate.

[0082] Wherein, 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 stably support the drum 21 in 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. In the process of the drum 21 rotating along its own circumference under the drive of the second drive assembly, since the support component can rotate relative to the mounting component, the support component will not interfere with the rotational movement 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 member set 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 and repair work. For example, the cleaning parts with greater wear and tear are removed from the roller 21, and new cleaning parts are installed on the roller 21, or a new roller 21 is replaced. When the replacement or maintenance is completed, the support component is at least partially inserted into the roller 21, and the roller 21 is installed on the connector 95 and the second bearing 93, and then connected to the second installation part 33 through the installation component, so that the roller 21 can be stably installed and supported in the installation groove, and the operation is convenient and efficient.

[0083] See also Figures 5 to 9 The supporting component of the supporting assembly 50 includes a connecting shaft 51 and a supporting body 52. ​​The connecting shaft 51 is coaxially arranged with the drum 21, and one end of the connecting shaft 51 is connected to the mounting component and can rotate relative to the mounting component along its own circumferential direction. The supporting body 52 is connected to the other end of the connecting shaft 51, and the supporting body 52 is at least partially arranged in the drum 21 to support the drum 21 and improve the stability of the drum 21 during rotation and movement.

[0084] like Figure 6As shown, a first groove 521 is provided on one side of the support body 52 close to the mounting component, a connecting hole 522 is provided at the bottom of the first groove 521, at least a portion of the connecting shaft 51 along its own axial direction is embedded in the connecting hole 522, and the mounting component is at least partially sleeved in the first groove 521 and rotatably connected to a side of the connecting shaft 51 away from the connecting hole 522 along the first direction. Since the connecting shaft 51 can rotate relative to the mounting component, during the rotation of the drum 21, the support body 52 connected to the connecting shaft 51 can rotate with the drum 21, thereby not interfering with the rotation of the drum 21, and improving the stability of the drum 21 during the movement and / or rolling process. In addition, since the mounting component is at least partially received and rotatably connected to the first groove 521 of the support body 52 through the connecting shaft 51, the structure of the entire support assembly 50 can be made more compact and reliable. Furthermore, when the support body 52 is passed through the drum 21 and supports the drum 21, the mounting component will not increase the distance between the drum 21 and the second mounting 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 clean along the edge.

[0085] like Fig. 9 As shown, the surface of the connecting shaft 51 is provided with a knurled portion 511, and the knurled portion 511 abuts against the inner wall surface of the connecting hole 522 to improve the firmness and reliability of the connection between the connecting shaft 51 and the connecting hole 522 of the support body 52, and to prevent the support body 52 from shaking relative to the connecting shaft 51 and affecting the support stability. The cleaning mechanism in this embodiment also includes a plug-in assembly. The support body 52 is detachably connected to the drum 21 through the plug-in assembly, so that when the support assembly 50 needs to be replaced or maintained, the support body 52 can be removed from the drum 21.

[0086] like Figure 5 As shown, when the support body 52 is a column structure (such as 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 peripheral 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 the plug protrusion 524 is provided on at least one of the outer peripheral surface of the support body 52 and the inner wall surface of the drum 21. Thus, by plugging and matching the plug protrusion 524 with the plug groove 523, the support body 52 is detachably inserted into the drum 21, which not only facilitates the installation and disassembly 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 stably rotate with the drum 21, and ensuring the stability of the drum 21 during rotation and movement.

[0087] Specifically, the outer circumferential surface of the support body 52 is provided with a plurality of plug-in protrusions 524 and a plurality of plug-in grooves 523 along its own circumference, and each plug-in groove 523 is located between two adjacent plug-in protrusions 524. The inner wall surface of the drum 21 is provided with a plurality of plug-in protrusions 524 and a plurality of plug-in grooves 523 along its own circumference, and each plug-in groove 523 is located between two adjacent plug-in protrusions 524. Among them, a boss 525 can also be provided at the bottom of the plug-in groove 523 on the outer circumferential surface of the support body 52, so that when the support body 52 and the drum 21 are plugged together, the boss 525 abuts against the plug-in protrusion 524 in the drum 21, thereby further improving the firmness and reliability between the support body 52 and the drum 21. Specifically, the boss 525 may be one or more strip 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 bosses 525 protruding from the outer peripheral surface of the support body 52 is less than the height of the insertion bosses 524 located on the support body 52 protruding from the outer peripheral surface of the support body 52. ​​Moreover, in this embodiment, the bosses 525 for increasing the firmness and reliability between the support body 52 and the drum 21 are disposed on the outer peripheral surface of the support body 52, which is convenient for processing.

[0088] like Figure 7 As shown, the mounting component of the support assembly 50 includes 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 connected to the main body 53 and is detachably buckled with the second mounting portion 33. 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, so that the roller 21 connected to the support assembly 50 can be conveniently removed.

[0089] like Figure 8 and Fig.10 As shown, a second groove 331 is provided on one side of the second mounting portion 33 close to the buckling portion 54, and the buckling portion 54 includes an elastic member 541 and a buckling joint 542. One end of the elastic member 541 along the first direction is connected to the main body 53. The buckling joint 542 is adapted to the second groove 331, and the buckling joint 542 is connected to one end of the elastic member 541 away from the main body 53. The buckling joint 542 has a third position where it is buckled in the second groove 331 under the elastic force of the elastic member 541, and a fourth position where it leaves the second groove 331. When the buckling joint 542 is located at the third position, the support assembly 50 is buckled with the second mounting portion 33 through the buckling joint 542. When the drum 21 needs to be removed, the elastic member 541 is compressed so that the buckling joint 542 moves to the fourth position where it leaves the second groove 331 under the action of the elastic member 541.

[0090] like Figure 7 , Figure 8 as well as Fig.10As shown, in order to facilitate the buckling joint 542 to be buckled into the second groove 331 of the second mounting portion 33 or to leave the second groove 331, the buckling portion 54 in this embodiment further includes a connecting block 543, which is connected to one end of the elastic member 541 away from the main body 53, and the buckling joint 542 is arranged on a side of the connecting block 543 away from the elastic member 541, and along the first direction, the projected outer contour of the connecting block 543 is at least partially misaligned with the projected outer contour of the second mounting portion 33. Therefore, when the buckling joint 542 is located in the second groove 331, the part of the connecting block 543 misaligned with the second mounting portion 33 can be pressed, so that the elastic member 541 generates elastic contraction under the action of the pressing force applied to the connecting block 543 to drive the buckling joint 542 to leave the second groove 331.

[0091] That is to say, the operator only needs to press the connection block 543 to remove the roller 21 from the bracket 30, and the operation is efficient and convenient. When the roller 21 needs to be installed on the bracket 30, after the roller 21 is connected to the second drive assembly, the buckle 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, and thus, the buckle joint 542 is separated from the second groove 331 by pressing the connection block 543 to compress the spring, thereby realizing the disassembly of the roller 21. By adjusting the distance between the connection block 543 and the main body 53 by utilizing the compression and extension force of the spring, the buckle joint 542 is buckled into the second groove 331, and the installation of the roller 21 can be realized.

[0092] like Figure 7 and Fig.10 As shown, at least two buckle joints 542 may be provided on the connection block 543, and at least two buckle joints 542 are located along the third direction (the third direction is Figure 2 At least two second grooves 331 are provided at one end of the second mounting portion 33 close to the connecting block 543, and the at least two second grooves 331 are provided in a one-to-one correspondence with the at least two snap joints 542, so as to improve the assembly stability between the support assembly 50 and the second mounting portion 33 by snapping the at least two snap joints 542 into the at least two second grooves 331, respectively. In some other embodiments, the second groove 331 may be provided at one end of the connecting block 543 close to the second mounting portion 33, and the snap joint 542 may be provided at one end of the second mounting portion 33 close to the connecting block 543, so as to separate the second groove 331 from the snap joint 542 on the second mounting portion 33 by pressing the connecting block 543, so as to realize the disassembly of the drum 21, and therefore, the specific setting positions of the snap joint 542 and the second groove 331 are not limited in this embodiment.

[0093] The second mounting portion 33 is arranged along the second direction (the second direction is Figure 2 An open groove 332 is provided at one end of the main body 53 (in the direction indicated by the arrow Y in the middle). 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. Therefore, the buckle 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 realizing 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 through 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 member 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.

[0094] like Figure 7 As shown, a protrusion 532 is provided on one side of the main body 53 of the mounting component close to the second mounting portion 33, and a limiting groove 333 is provided on one side of the second mounting portion 33 close to the main body 53. The limiting groove 333 is located on one side of the opening groove 332 close to the bracket body 31 along the second direction. The limiting groove 333 is connected to the opening groove 332, which reduces the processing difficulty of the limiting groove 333. The protrusion 532 abuts against the limiting groove 333 to further improve the assembly stability between the main body 53 and the second mounting portion 33 during the rotation and movement of the drum 21, and prevent the buckle joint 542 from being separated from the second mounting portion 33 due to the shaking of the main body 53 under the rotation, rolling or movement of the drum 21. At present, the protrusion 532 in this embodiment can also be set on one side of the second mounting portion 33 close to the main body 53, and the limiting groove 333 is set on one side of the main body 53 close to the second mounting portion 33, and this embodiment does not make a sole limitation on this.

[0095] like Figures 8 to 10As shown, 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 avoidance hole 5331 is provided in the first mounting seat 533 along the first direction. The first bearing 534 is located in the first avoidance hole 5331, and the outer peripheral surface of the first bearing 534 is connected to the inner wall surface of the first avoidance hole 5331. The connecting shaft 51 is at least partially penetrated in the first avoidance hole 5331 and connected to the inner peripheral surface of the first bearing 534. One end of the connecting shaft 51 away from the first avoidance 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, and there is an installation gap 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 buckle portion 54 is connected to a side of the second mounting seat 535 close to the second mounting portion 33 to buckle with the second mounting portion 33. In this embodiment, there may be two first bearings 534, which are arranged side by side in the first avoidance hole 5331 along the first direction and connected to the connecting shaft 51. The outer circumferences of the two first bearings 534 are connected to the inner wall surface of the first avoidance hole 5331, and the inner circumferences are connected to the connecting shaft 51, thereby improving the assembly strength and rotation reliability between the connecting shaft 51 and the first mounting seat 533.

[0096] Secondly, when the snap-on 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 snap-on and disassembly operations between the snap-on joint 542 and the second groove 331.

[0097] Specifically, Fig.10As shown, 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 arranged 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 arranged on a side of the second mounting seat 535 close to the second mounting portion 33. A plurality of first guide posts 56 are arranged at intervals along the circumference of the drum 21 at the bottom of the third groove 531, a first guide hole is arranged in the first guide post 56, a guide rod is arranged in the first guide hole, the outer diameter of the guide rod is smaller than the first guide hole, and one end of the guide rod can be detachably locked in the first guide hole by a locking member such as a screw or a screw. A plurality of second guide posts 57 are arranged one by one with the first guide holes and are located on the connection block 543. The outer diameter of the second guide posts 57 is adapted to the inner diameter of the first guide holes. A second guide hole is arranged in the second guide posts 57. The inner diameter of the second guide hole is adapted to the outer diameter of the guide rod. When the second guide posts 57 are inserted into the first guide holes, the second guide holes are inserted into the guide rods. In the process of pressing or stretching the connection block 543, the second guide posts 57 can be inserted into the guide rods of the first guide holes and reciprocated relative to the guide rods along the first direction to ensure that the connection block 543 will not shake relative to the second mounting seat 535 during the pressing of the connection block 543, thereby reducing the difficulty of fastening and disassembly between the buckle joint 542 and the second groove 331. Specifically, at least two second guide posts 57 on the connection block 543 are respectively connected to the side of at least two buckle joints 542 away from the second mounting portion 33, further improving the accuracy of the buckle joints 542 when they are fastened or separated from the second groove 331 under the action of the elastic member 541. This prevents the buckle joint 542 from shaking with the connecting block 543 and being difficult to buckle into the second groove 331 or difficult to separate from the second groove 331 .

[0098] In addition, since the first guide column 56 and the second guide column 57 are both located in the third groove 531, the structure of the installation component is more compact and easy to assemble. In addition, the installation distance between the drum 21 and the second installation portion 33 will not be increased, ensuring that the cleaning member on the drum 21 can perform edge cleaning. Therefore, in this embodiment, the first guide column 56 and the second guide column 57 guide the connecting block 543 so that the buckle joint 542 can be stably and accurately buckled or separated from the second groove 331, and it can also ensure that the cleaning member set on the drum 21 can perform edge cleaning.

[0099] The support body 52 is provided with a second avoidance hole 526, and the main body 53 in this embodiment further includes a connecting protrusion 536 and a connecting column 537. The connecting protrusion 536 is provided on a side of the first mounting seat 533 close to the second mounting seat 535, and a third avoidance hole 361 is provided in the connecting protrusion 536. The third avoidance hole 361 penetrates the first mounting seat 533 along the first direction and communicates with the second avoidance hole 526. The connecting column 537 is provided on a side of the second mounting seat 535 close to the first mounting seat 533, and the connecting column 537 is penetrated in the third avoidance hole 361 and connected to the first mounting seat 533 through 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 at the third avoidance hole 361 along the second avoidance hole 526 to fix the connecting column 537 and the first mounting seat 533, thereby improving the 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. When there are multiple second avoidance holes 526, they can be provided around the outer periphery of the connecting hole 522 along the circumferential direction of the support body 52. ​​Since the support body 52 can drive the connecting shaft 51 to rotate relative to the first mounting seat 533 along with the roller 21, whether there is one or more second avoidance holes 526, it is only necessary to rotate the support body 52 to make any second avoidance hole 526 correspond to and communicate with the third avoidance hole 361, and then the locking member can be placed along the second avoidance hole 526 at the third avoidance hole 361 to fix the connecting column 537 with the first mounting seat 533.

[0100] like Fig.10 As shown, in order to make the connection between the first mounting seat 533 and the second mounting seat 535 more firm and reliable, a plurality of connecting protrusions 536 may be provided on the first mounting seat 533, and a plurality of connecting columns 537 may be provided on the second mounting seat 535 accordingly. At this time, the plurality of second avoidance holes 526 provided on the support body 52 may be rotated to correspond to the plurality of third avoidance holes 361 in the connecting protrusions 536, respectively, so that the first mounting seat 533 and the second mounting seat 535 are connected together by a plurality of locking members at the same time, further improving the assembly efficiency between the first mounting seat 533 and the second mounting seat 535. The locking member in this embodiment may include at least one of a screw, a screw, a stud, etc.

[0101] 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, and is used to restrict 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, so that the first bearing 534 is restricted on the connecting shaft 51 by the snap ring 55 sleeved on the connecting shaft 51 to prevent the first bearing 534 from falling off the connecting shaft 51.

[0102] 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 covers the end of the bracket 30 extending from the outer peripheral edge of the body 10. The flexible protective cover is used to prevent the support assembly 50 and / or the bracket 30 from hitting furniture, walls, etc. during the cleaning process of the cleaning body 20 along the edge, and to prevent the support assembly 50 and / or the bracket 30 from hitting furniture, walls, or being damaged by furniture or walls. Specifically, when the drum 21 of the support assembly 50 moves with the bracket 30 to the first position extending from the outer peripheral 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 peripheral edge of the body 10, and the second mounting portion 33 of the bracket 30 is also located at the outer peripheral edge of the body 10. In order to avoid the second mounting seat 535 and the second mounting portion 33 from hitting 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 misaligned with the second mounting portion 33 is in contact with the second mounting portion 33, the first protective cover can cover the portion of the second mounting seat 535 misaligned with 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, so as to prevent the bracket 30 from hitting the furniture through the second protective portion.

[0103] In this embodiment, both the first mounting portion 32 and the second mounting portion 33 can be plate-shaped structures to ensure that the cleaning member mounted on the drum 21 can clean the corner area along the edge. Secondly, the bracket body 31 is an arc-shaped plate-shaped structure adapted to the outer surface of the drum 21, and the arc-shaped plate-shaped structure covers the drum 21 to improve the structural strength of the entire cleaning mechanism.

[0104] 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 component. Figure 2 and Figure 3 As shown, 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 along the first direction with the bracket 30 relative to the slider 70. In this embodiment, the cleaning body 20 is guided to move smoothly along the first direction with the bracket 30 through the sliding cooperation 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. By contrast, this embodiment is not the only limitation.

[0105] In addition, since the cleaning body 20 needs to be lifted along the second direction to leave the surface to be cleaned when the cleaning is completed or when obstacles need to be overcome, in this regard, when the slider 70 is installed on the body 10, the embodiment can connect the slider 70 to the third driving assembly through a pulling rope, and the third driving assembly is used to drive the pulling rope to lift the cleaning body 20 on the bracket 30 along the second direction, so that the cleaning body 20 leaves the surface to be cleaned or approaches the surface to be cleaned. In order to improve the convenience of connection between the pulling rope and the slider 70, the pulling rope in this embodiment is provided with an abutment portion, and the slider 70 is provided with an abutment hole, and a notch is provided on one side of the abutment hole. The size of the abutment hole and its notch is larger than the size of the pulling rope and smaller than the size of the abutment portion. After the pulling rope is moved into the abutment hole along the notch, the pulling rope is tightened by the third driving assembly so that the abutment portion abuts against the side of the abutment hole close to the slide rail, and there is no need to use a locking member to lock the pulling rope and the slider 70, which is convenient to operate and reliable. The abutment portion can be a sphere with a diameter larger than the diameter of the abutment hole.

[0106] like Figure 2 As shown, the cleaning device provided in this embodiment further includes a stopper 80, which is installed in the body 10 and located between the guide rail 71 and the rack 43. Along the first direction, the projected outer contour of the stopper 80 is at least partially located within the projected outer contour of the guide rail 71 and the projected outer contour of the rack 43. When the motor of the first driving assembly 40 drives the bracket 30 to move the cleaning body 20 to the first position, the guide rail 71 is abutted against the stopper 80, thereby limiting the cleaning body 20 to the first position, preventing the bracket 30 from continuing to move and causing the cleaning body 20 to separate from the body 10. After the cleaning body 20 completes the edge cleaning, the motor reverses to drive the rack 43 to drive the bracket 30 to move to the second position, and the cleaning body 20 is limited to the second position by abutting the rack 43 against the stopper 80.

[0107] In addition, if Figure 4 As shown, a water supply channel 312 and a plurality of water spray ports are provided in the bracket body 31. The water supply channel 312 is laid in the bracket body 31 along the first direction. The water spray ports are provided on a side of the bracket body 31 close to the cleaning body 20 and are connected to the water supply channel 312. At least one or more water spray ports are provided opposite to at least a portion of the cleaning body 20 extending 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 ports, so that the cleaning body 20 is soaked and self-cleaned to better clean the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency. And since at least one or more water spray ports are provided opposite to at least a portion of the cleaning body 20 extending outside the body 10, when the cleaning body 20 is cleaning along the edge, the portion of the cleaning body 20 extending outside the body 10 can also be soaked and self-cleaned to achieve better cleaning effect and cleaning efficiency.

[0108] The water supply channel 312 of the bracket body 31 is covered with a cover plate 311, and a connecting pipe connected to the clean water tank can be provided on the cover plate 311. The clean water tank is provided with a water pump to provide liquid to the water supply channel 312 and enable the liquid to be sprayed onto the cleaning parts of the cleaning body 20 through the water spray port. The liquid can be clean water, cleaning liquid, or a mixture of clean water and cleaning liquid, so that the cleaning parts are kept just wet, thereby improving the cleaning ability of the cleaning parts. The bracket body 31 is also connected to a wiper strip 34, which is interference-fitted with the cleaning parts on the drum 21 to scrape off the sewage and garbage on the cleaning parts during the rotation of the drum 21.

[0109] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0110] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0111] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
