Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0063] At present, the side of the drum 30 of the cleaning device away from the driving component 40 is suspended (i.e., a cantilever beam structure). The drum 30 of the cantilever beam structure is prone to shaking during operation, which makes the stability of the drum 30 poor, which not only affects the service life of the drum 30, but also may reduce the cleaning effect of the drum 30 on the ground, and easily leave more obvious dirt marks on the ground. In this regard, the first embodiment of the utility model introduces a cleaning mechanism, which is used for cleaning equipment. The bottom of the body 10 of the cleaning device in this embodiment is provided with a storage chamber 11, and the cleaning mechanism is installed in the storage chamber 11.

[0064] Specifically, see Figures 1 to 11 The cleaning mechanism includes a bracket 20 and a cleaning body. Figures 2 to 4 As shown, the cleaning body includes a roller 30, a driving component 40 and a supporting assembly 50. The driving component 40 is connected to one end of the bracket 20 along the first direction and is at least partially disposed in the roller 30. The driving component 40 is used to drive the roller 30 to rotate around its own axis. The first direction in this embodiment is parallel to the length direction of the roller 30. The first direction is specifically as follows Figure 2 and Figure 3 The first direction indicated by the arrow X is a direction parallel to the axial direction of the drum.

[0065] The drum 30 can generally be composed of a drum body and a mop laid on the drum body. The drum 30 can rotate around its own axis to improve the cleaning effect of the surface to be cleaned during the rotation process. Among them, the support assembly 50 includes a mounting component 51 and a support component 52. The mounting component 51 is connected to the other end of the bracket 20 along the first direction, the support component 52 is connected to the mounting component 51 and can rotate with the drum 30 relative to the mounting component 51, and the support component 52 is at least partially penetrated in the drum 30 to support the drum 30. As a result, both ends of the drum 30 along its own axis are supported, which can improve the stability of the drum 30 during operation (such as rotation). At the same time, in order to reduce or even eliminate the blind spot of cleaning, the drum 30 is configured to be movable relative to the main body 10 of the cleaning device so that the drum 30 can be extended from the main body 10 to clean along the edge. Since the end of the drum 30 away from the driving component 40 is supported by the supporting component 52, the stability of the drum 30 during rotation and / or movement can be improved, the smoothness of the movement of the drum 30 can be improved, and the cleaning efficiency and cleaning effect of the drum 30 can be improved.

[0066] It can be seen that one end of the roller 30 of the cleaning mechanism provided in this embodiment is connected to the driving component 40, and the driving component 40 is inserted into the roller 30 to drive the roller 30 to rotate. The end of the roller 30 away from the driving component 40 is internally penetrated with a supporting component 52 of the supporting assembly 50, so that the roller 30 is supported by the supporting component 52, so that the roller 30 is supported on both sides along its own axis, thereby improving the stability of the roller 30 during operation. At the same time, the supporting component 52 is connected to the mounting component 51 and can rotate with the roller 30 relative to the mounting component 51. The mounting component 51 is connected to the other end of the bracket 20 along the first direction, so that during the rotation of the roller 30, the supporting component 52 supports the roller 30 without interfering with the rotation of the roller 30, thereby improving the stability and reliability of the overall structure of the cleaning body.

[0067] Specifically, Figure 3As shown, the bracket 20 in this embodiment may include a bracket body 21, a first mounting portion 22 and a second mounting portion 23, and the first mounting portion 22 and the second mounting portion 23 are respectively located at opposite ends of the bracket body 21 along the first direction. The drum 30 is connected between the first mounting portion 22 and the second mounting portion 23 through a driving component 40 and a supporting assembly 50. Specifically, the driving component 40 can be detachably connected with the second mounting portion 23 through a locking member (such as at least one of a screw, a bolt, etc.), and the drum 30 is sleeved on the driving component 40 and can move relative to the driving component 40 along its own axial direction to a position separated from the driving component 40. One end of the drum 30 close to the first mounting portion 22 is supported by the supporting assembly 50 and connected to the first mounting portion 22, so that both ends of the drum 30 are effectively supported, thereby improving the stability of the drum 30 during operation.

[0068] See also Figure 3 The driving component 40 in this embodiment may specifically include a disassembly and assembly part 41, a bearing seat 42, a second bearing 43, a driving motor 44 and a connector 45. The drum 30 is sleeved on the driving component 40 so that the drum 30 can move along its own axial direction under the action of external force to separate from the driving component 40. Specifically, the disassembly and assembly part 41 is connected to the second mounting part 23, the driving motor 44 is connected to one end of the disassembly and assembly part 41 away from the second mounting part 23 through the bearing seat 42, the second bearing 43 is arranged on the bearing seat 42, and the inner circumferential surface of the second bearing 43 is connected to the bearing seat 42. The connector 45 is located on the side of the driving motor 44 away from the second bearing 43 and is connected to the driving motor 44. The connector 45 rotates along its own circumferential direction under the drive of the driving motor 44. The connector 45 is detachably inserted into the drum 30 to drive the drum 30 to rotate along its own axial direction, and the drum 30 cleans the floor during the rotation process. The side of the drum 30 away from the supporting assembly 50 is sleeved on the second bearing 43, so that the drum 30 is driven to rotate through the connecting head 45 and the second bearing 43, and the side of the drum 30 away from the supporting assembly 50 is supported. Therefore, in this embodiment, the drum 30 is supported by the supporting assembly 50, the second bearing 43 and the connecting head 45, and the stability of the drum 30 during rotation and movement is further improved.

[0069] Among them, Figure 5 and Figure 6As shown, the support component 52 includes a connecting shaft 521 and a supporting body 522. The connecting shaft 521 is coaxially arranged with the drum 30 so that the support component 52 can stably rotate with the drum 30. One end of the connecting shaft 521 is connected to the mounting component 51 and can rotate around its own axis relative to the mounting component 51. The supporting body 522 is connected to the other end of the connecting shaft 521, and the supporting body 522 is at least partially penetrated into the drum 30 to support the drum 30. After the mounting component 51 is connected to the bracket 20, since the connecting shaft 521 can rotate relative to the mounting component 51, when the drum 30 rotates, the supporting body 522 connected to the connecting shaft 521 can rotate with the drum 30, thereby improving the stability of the drum 30 during rotation. It can be seen that the support component 52 in this embodiment can not only stably support the drum 30, but also will not interfere with the normal operation of the drum 30. The overall structure of the support component 52 is simple and stable, and the assembly efficiency between the support component 52 and the mounting component 51 is high.

[0070] like Figure 5 and Figure 7 As shown, a first groove 523 is provided on one side of the support body 522 close to the mounting member 51, and the mounting member 51 is at least partially sleeved in the first groove 523. Thus, at least a portion of the mounting member 51 is received and rotatably connected to the first groove 523 of the support body 522 through the connecting shaft 521, which can make the structure of the entire support assembly 50 more compact, reliable, and strong. In addition, when the support body 522 is inserted into the drum 30 and supports the drum 30, the mounting member 51 will not increase the distance between the drum 30 and the first mounting portion 22 along the first direction, so that while the drum 30 is supported by the support assembly 50, the cleaning blind area when the drum 30 extends out of the body 10 for cleaning can be reduced, so that the drum 30 can be cleaned along the edge.

[0071] See also Figure 7The support body 522 in this embodiment includes a support body 5221 and a boss 5222. The first groove 523 is arranged in the support body 5221, and the support body 5221 is penetrated in the drum 30 and is in contact with the inner wall surface of the drum 30 to achieve the support function for the drum 30. The boss 5222 is arranged at the bottom of the first groove 523. A connecting hole 2221 is arranged in the boss 5222, and the connecting hole 2221 penetrates the boss 5222 along the first direction and is coaxially arranged with the drum 30. The connecting shaft 521 is penetrated in the connecting hole 2221 along one side of its own axial direction and is fixedly connected to the boss 5222 to improve the connection strength between the connecting shaft 521 and the support body 522. The mounting component 51 is rotatably connected to the side of the connecting shaft 521 away from the boss 5222 along the first direction. When the drum 30 rotates, the support body 5221 connected to the connecting shaft 521 rotates with the drum 30. Since the connection strength between the connecting shaft 521 and the support body 522 is high, the connecting shaft 521 is not easy to slide relative to the support body 5221, thereby improving the reliability of the support body 522.

[0072] In order to further improve the connection strength between the connecting shaft 521 and the supporting body 522, a clamping structure 524 is provided between the connecting shaft 521 and the supporting body 522 in this embodiment. Figure 5 and Figure 8 As shown, the clamping structure 524 includes a clamping protrusion 241 and a clamping groove 242. The clamping protrusion 241 is arranged on at least one of the connecting shaft 521 and the supporting body 522. The clamping groove 242 is adapted to the clamping protrusion 241, and the clamping groove 242 is arranged on at least one of the connecting shaft 521 and the supporting body 522. Specifically, the clamping protrusion 241 and the clamping groove 242 can be arranged on the connecting shaft 521 at the same time. When the supporting body 522 is obtained by injection molding on the connecting shaft 521, the clamping protrusion 241 on the connecting shaft 521 is embedded in the supporting body 522, and the clamping groove 242 on the connecting shaft 521 will be filled with the raised portion of the supporting body 522 (equivalent to the clamping protrusion 241), so that the connection strength between the connecting shaft 521 and the supporting body 522 is higher. As shown Figure 5 As shown, the clamping protrusion 241 on the connecting shaft 521 is embedded in the clamping groove 242 located on the inner wall surface of the connecting hole 2221, and the clamping protrusion 241 on the inner wall surface of the connecting hole 2221 is embedded in the clamping groove 242 of the connecting shaft 521. Therefore, in this embodiment, the connection strength between the connecting shaft 521 and the boss 5222 of the supporting body 522 is improved through the nested cooperation between the clamping protrusion 241 and the clamping groove 242.

[0073] like Figure 8As shown, the clamping protrusion 241 in this embodiment is preferably a knurled boss 2411, and the knurled boss 2411 is convexly arranged on the surface of the connecting shaft 521. The knurled boss 2411 is provided with a knurled structure along the radial direction of the connecting shaft 521 away from the surface of the connecting shaft 521. The knurled structure (such as straight knurling, net knurling and other structures) has an anti-slip effect, that is, the surface roughness of the knurled boss 2411 in contact with the support body 522 is relatively large, which can increase the friction between the knurled boss 2411 and the support body 522. Therefore, when the knurled boss 2411 is embedded in the connecting hole 2221 of the boss 5222, the connection strength between the connecting shaft 521 and the boss 5222 can be improved. In addition, the knurled boss 2411 is easy to process, and a knurling tool is used on a lathe to roll the boss surface on the surface of the connecting shaft 521 to form a straight or net knurled structure.

[0074] See also Figure 6 A plug-in structure 525 is provided between the support body 522 and the inner wall surface of the drum 30. The support body 522 has a first position where it is plugged into the drum 30 through the plug-in structure 525 under the action of an external force, and a second position where it is separated from the drum 30. When the support assembly 50 needs to be replaced or maintained, the support body 522 can be removed from the drum 30 by making the support body 522 overcome the force of the plug-in structure 525 when plugging it with the drum 30. Usually, the support assembly 50 does not need to be removed from the drum 30. When the drum 30 is installed on the bracket 20, it can be connected to the bracket 20 through the mounting component 51 of the support assembly 50, which is convenient for operation. Moreover, keeping the support assembly 50 on the drum 30 can also ensure that the support assembly 50 will not be accidentally lost after the drum 30 is taken out of the cleaning device.

[0075] The support body 522 in this embodiment includes a columnar structure that is compatible with the inner wall surface of the drum 30 (that is, the support body 5221 is a columnar structure as a whole). When the support body 5221 of the columnar structure supports the drum 30, the contact area between the drum 30 and the support body 522 is larger, and each part of the drum 30 along its own circumference can contact the support body 522 and be supported by the support body 522, thereby preventing the inner wall surface of the drum 30 from being unable to be supported in some areas, thereby preventing the drum 30 from having local stress concentration and causing instability, thereby improving the support effect on the drum 30.

[0076] Specifically, Figure 6As shown, the plug-in structure 525 in this embodiment includes a plug-in groove 251 and a plug-in protrusion 252. The plug-in groove 251 is provided on at least one of the outer circumferential surface of the support body 522 and the inner wall surface of the drum 30. That is, the plug-in groove 251 can be provided on both the outer circumferential surface of the support body 522 and the inner wall surface of the drum 30, or only the outer circumferential surface of the support body 522 or the inner wall surface of the drum 30 is provided with the plug-in groove 251, and this embodiment does not make a sole limitation on this. The plug-in protrusion 252 is adapted to the plug-in groove 251, and the plug-in protrusion 252 is provided on at least one of the outer circumferential surface of the support body 522 and the inner wall surface of the drum 30. That is, both the outer circumferential surface of the support body 522 and the inner wall surface of the drum 30 may be provided with the plugging protrusion 252, or only the outer circumferential surface of the support body 522 or the inner wall surface of the drum 30 may be provided with the plugging protrusion 252. This embodiment does not make a sole limitation on this, as long as it can ensure that the support body 522 and the drum 30 can be plugged into the drum 30 through the plugging fit between the plugging protrusion 252 and the plugging groove 251. It can be seen that in this embodiment, the support body 522 is detachably plugged into the drum 30 through the plugging fit between the plugging groove 251 and the plugging protrusion 252, which not only facilitates the installation and disassembly of the support assembly 50, but also increases the friction between the support body 522 and the drum 30, thereby ensuring that the support body 522 can stably rotate with the drum 30, and improving the stability of the drum 30 during the rotation and / or movement process.

[0077] like Figure 6 As shown, the insertion grooves 251 and the insertion protrusions 252 in this embodiment each include a plurality of insertion grooves 251 and a plurality of insertion protrusions 252, which are staggeredly arranged on the outer peripheral surface of the support body 522 along the circumferential direction of the support body 522, that is, the insertion grooves 251 on the support body 522 are located between two adjacent insertion protrusions 252. At the same time, the plurality of insertion grooves 251 and the plurality of insertion protrusions 252 are staggeredly arranged on the inner wall surface of the drum 30 along the circumferential direction of the drum 30, that is, the insertion grooves 251 on the inner wall surface of the drum 30 are located between two adjacent insertion protrusions 252. Therefore, this embodiment connects the support body 522 and the inner wall of the drum 30 through multiple plug-in grooves 251 and multiple plug-in protrusions 252 on the outer circumferential surface of the support body 522 and the inner wall of the drum 30, so that all parts of the inner wall of the drum 30 along its own circumference can contact the support body 522. During the rotation of the drum 30, the forces on all parts of the inner wall of the drum 30 along its own circumference are balanced, avoiding the local generation of large stress concentration during the rotation of the drum 30, thereby improving the stability and reliability of the working process of the drum 30.

[0078] In order to make the connection between the support body 522 and the drum 30 more firm and stable, the plug-in structure 525 may further include abutting convex strips 253. The abutting convex strips 253 are arranged at the bottom of the plug-in grooves 251 on the outer peripheral surface of the support body 522, so that when the support body 522 and the drum 30 are plugged together, the abutting convex strips 253 abut against the plug-in protrusions 252 in the drum 30, thereby improving the firmness and reliability between the support body 522 and the drum 30. Specifically, along the radial direction of the drum 30, the protrusion height of the abutting convex strip 253 protruding from the outer peripheral surface of the support body 522 is less than the protrusion height of the plugging protrusion 252 located on the support body 522 protruding from the outer peripheral surface of the support body 522, so that the plugging groove 251 of the support body 522 can be plugged with the plugging protrusion 252 in the drum 30, and the installation gap between the plugging groove 251 and the plugging protrusion 252 is filled by the abutting convex strip 253, so that the connection between the support body 522 and the drum 30 is more firmly established. Moreover, in this embodiment, the abutting convex strip 253 is arranged on the outer peripheral surface of the support body 522, which is more convenient for processing.

[0079] See also Fig. 9 and Fig.10 In order to make the connection between the mounting component 51 and the bracket 20 more convenient and quick, a locking structure 201 is provided at one end of the bracket 20 close to the mounting component 51 in this embodiment. At this time, the mounting component 51 may include a mounting body 511 and a locking body 512, and the mounting body 511 is rotatably connected to the supporting component 52. The locking body 512 is movably arranged on one side of the mounting body 511 close to the locking structure 201, and the locking body 512 has a locking position that is buckled with the locking structure 201 and an unlocking position that is separated from the locking structure 201. After the drum 30 is connected to the mounting body 511 of the mounting component 51 through the supporting component 52, the drum 30 can be installed on the bracket 20 by placing the locking body 512 in the locking position that is buckled with the locking structure 201 on the bracket 20. When the roller 30 needs to be removed from the bracket 20, the roller 30 can be removed from the bracket 20 by placing the lock body 512 in an unlocked position separated from the locking structure 201. The disassembly and assembly is simple and convenient, which can reduce the disassembly and assembly workload of the operator and improve the disassembly and assembly efficiency. The specific structure of the lock body 512 can adopt the content provided in the second embodiment of the utility model.

[0080] In order to solve the problem of cumbersome disassembly and inconvenience of assembly and disassembly of the drum 30, the second embodiment of the utility model provides a cleaning mechanism, which is used for cleaning equipment, which may include a sweeping robot, a mopping machine, etc. The cleaning mechanism provided in this embodiment includes a bracket 20 and a cleaning body.

[0081] See also Figures 5 to 11, a locking structure 201 is provided on the bracket 20. The cleaning body includes a roller 30 and a mounting component 51, and the mounting component 51 includes a mounting body 511 and a locking body 512. The mounting body 511 is connected to the roller 30, and the locking body 512 is movably arranged on a side of the mounting body 511 close to the locking structure 201, and the locking body 512 has a locking position buckled with the locking structure 201 and an unlocking position separated from the locking structure 201. After the roller 30 is connected to the mounting body 511 of the mounting component 51, the roller 30 can be installed on the bracket 20 by making the locking body 512 in the locking position buckled with the locking structure 201 on the bracket 20. When the roller 30 needs to be removed from the bracket 20, the roller 30 can be removed from the bracket 20 by making the locking body 512 in the unlocking position separated from the locking structure 201. The disassembly and assembly is simple and convenient, which can reduce the disassembly and assembly workload of the operator and has high disassembly and assembly efficiency.

[0082] It can be seen that in this embodiment, a locking structure 201 is provided on the bracket 20 of the cleaning mechanism, and the installation component 51 of the cleaning body includes a mounting body 511 and a locking body 512. When the drum 30 is connected to the bracket 20 through the mounting body 511, the locking body 512 provided on the mounting body 511 is buckled with the locking structure 201 on the bracket 20, thereby retaining the drum 30 on the bracket 20. When the drum 30 needs to be removed, the locking body 512 is placed in an unlocked position separated from the locking structure 201, and the drum 30 can be removed from the bracket 20, which is convenient and simple to disassemble, and has high disassembly efficiency.

[0083] like Figure 5 and Fig.11 As shown, the lock body 512 in this embodiment includes an elastic element 121 and a buckle portion 122. One end of the elastic element 121 along its own expansion direction is connected to a side of the installation body 511 close to the locking structure 201. The expansion direction of the elastic element 121 is parallel to the first direction, that is, Figure 2 and Fig.11The direction indicated by the arrow X in the middle. The buckle part 122 is connected to one end of the elastic element 121 away from the installation body 511. The buckle part 122 has a locking position where it is buckled with the locking structure 201 under the elastic force of the elastic element 121, and an unlocking position where it is separated from the locking structure 201 under the action of an external force to overcome the elastic force of the elastic element 121. When the buckle part 122 is in the locking position, the drum 30 is buckled with the bracket 20 through the buckle part 122. When the drum 30 needs to be removed, the elastic element 121 is compressed by applying a compressive force to the elastic element 121, so that the buckle part 122 moves to the locking position separated from the locking structure 201 under the pulling force when the elastic element 121 is compressed. In this embodiment, the installation or disassembly between the drum 30 and the bracket 20 is realized by connecting and cooperating with the elastic element 121 and the buckle part 122, which is easy to operate, convenient and efficient to disassemble and assemble. The elastic element 121 in this embodiment can be a spring with low cost and convenient material.

[0084] like Figure 3 As shown, the bracket 20 in this embodiment includes a first mounting portion 22, and the locking structure 201 is disposed on the first mounting portion 22. The mounting body 511 is connected to one end of the drum 30 close to the first mounting portion 22. The locking body 512 also includes a pressing block 123, which is connected to one end of the elastic element 121 away from the mounting body 511, and the buckle portion 122 is disposed on a side of the pressing block 123 away from the elastic element 121. Along the first direction, the projected outer contour of the pressing block 123 is at least partially misaligned with the projected outer contour of the first mounting portion 22, that is, the pressing block 123 at least partially extends out of the first mounting portion 22.

[0085] Since the pressing block 123 in this embodiment at least partially extends out of the first mounting portion 22, when the buckle portion 122 is in the locked position, the pressing force applied to the pressing block 123 toward the mounting body 511 can be applied to the pressing block 123, so that the elastic element 121 generates elastic contraction under the action of the pressing force applied to the pressing block 123, and then the elastic element 121 can drive the buckle portion 122 to leave the locking structure 201 and arrive at the unlocking position, so as to conveniently separate the drum 30 from the bracket 20. In other words, the operator only needs to press the pressing block 123 to remove the drum 30 from the bracket 20, and the operation is efficient and convenient. When the drum 30 needs to be installed on the bracket 20, the buckle portion 122 is moved to the locked position buckled with the locking structure 201 under the extension of the elastic element 121. To facilitate the operator to apply pressing force to the pressing block 123, when the cleaning body is installed in the storage chamber 11 of the cleaning device (such as a sweeping robot), it is only necessary to ensure that there is a reserved installation space between the pressing block 123 and the cavity wall of the storage chamber 11. When at least one end of the storage chamber 11 along the first direction penetrates the body 10 of the cleaning device, at least one end of the body 10 along the first direction is an open end, and the operator can put his hand into the storage chamber 11 along the open end to press the pressing block 123.

[0086] like Figure 3 and Fig. 9 As shown, the first mounting portion 22 in this embodiment is further provided with an open groove 221, and the open groove 221 penetrates the first mounting portion 22 along the first direction. The locking structure 201 can be specifically provided at a position of the first mounting portion 22 close to the open groove 221. Along the first direction, the projected outer contour of the pressing block 123 is at least partially located within the projected outer contour of the open groove 221. When the buckling portion 122 is buckled with the locking structure 201, the pressing block 123 is at least partially penetrated into the open groove 221. At this time, the portion of the pressing block 123 penetrated into the open groove 221 can be specifically a columnar structure adapted to the inner circumference of the open groove 221, so as to facilitate manual pressing of the pressing block 123 for unlocking operation. When the drum 30 needs to be removed, the operator can push the buckling portion 122 on the pressing block 123 to separate from the locking structure 201 by pressing the portion of the pressing block 123 located in the open groove 221, thereby realizing the removal of the drum 30 from the bracket 20.

[0087] like Figure 4 , Figure 5 as well as Fig.11As shown, a mounting groove 513 is provided on one side of the mounting body 511 close to the locking body 512, and the locking body 512 is mounted in the mounting groove 513, so that the assembly structure between the pressing block 123 and the mounting body 511 is more compact, safe and reliable. In addition, the mounting space between the drum 30 and the first mounting portion 22 can be saved, and when the drum 30 is extended out of the cleaning device for edge cleaning, it is ensured that the drum 30 can be cleaned along the edge.

[0088] One side of the mounting groove 513 along the second direction is disposed opposite to the first mounting portion 22, and the other side is offset from the first mounting portion 22. Figure 4 and Fig.10 As shown, a clearance opening 131 is provided on one side of the mounting groove 513 relative to the first mounting portion 22. Along the first direction, the projected outer contour of the buckle portion 122 and the projected outer contour of the locking structure 201 are both located within the projected outer contour of the clearance opening 131. Thus, the distance between the first mounting portion 22 and the mounting body 511 can be further shortened by the clearance opening 131 provided at the notch of the mounting groove 513, so that the first mounting portion 22 can be buckled with the locking structure 201 and the buckle portion 122 in the clearance opening 131, thereby improving the strength and compactness of the overall structure of the cleaning body and making the appearance of the cleaning body more neat. Therefore, after the drum 30 is connected to the first mounting portion 22 through the buckle portion 122, the assembled structure of the drum 30 and the first mounting portion 22 is more compact and reliable.

[0089] The locking structure 201 in this embodiment may specifically include a buckling groove, and the buckling groove may include at least two. The buckling portion 122 includes a buckling protrusion adapted to the buckling groove. The buckling protrusion includes at least two buckling protrusions and is arranged in a one-to-one correspondence with the at least two buckling grooves, and the at least two buckling protrusions are arranged at intervals on the pressing block 123. In this embodiment, the stability of the buckling of the lock body 512 and the buckling groove on the first mounting portion 22 is improved by buckling at least two buckling protrusions with at least two buckling grooves in a one-to-one correspondence. Even if one of the buckling protrusions is separated from the buckling groove, it can ensure that the drum 30 can be connected to the first mounting portion 22 through the other buckling protrusion. When the drum 30 needs to be disassembled from the bracket 20 for maintenance or cleaning, the buckling protrusion can be separated from the buckling groove by pressing the pressing block 123 to compress the spring, thereby realizing the disassembly of the drum 30. When the roller 30 needs to be installed on the bracket 20 and then installed in the cleaning device, the distance between the pressing block 123 and the installation body 511 can be adjusted by using the compression and extension force of the spring, and the at least two buckling protrusions are buckled in the at least two buckling grooves one by one, so that the roller 30 can be installed on the bracket 20. Of course, in this embodiment, the buckling protrusions can also be used as the locking structure 201 on the bracket 20, and the buckling grooves can be used as the buckling part 122, and this embodiment is not limited to this.

[0090] The mounting body 511 is connected to the first mounting portion 22 via a limiting structure, and the mounting body 511 has a first position where it abuts against the first mounting portion 22 via the limiting structure under the action of an external force, and a second position where it is separated from the first mounting portion 22. Thus, during the process of the drum 30 rotating and / or moving forward with the cleaning device, the limiting structure can improve the stability of the mounting body 511 relative to the first mounting portion 22, prevent the mounting body 511 from deflecting along the circumference of the drum 30 due to the force generated by the movement of the drum 30, ensure that the mounting body 511 can be reliably connected to the first mounting portion 22, and further improve the stability of the buckling between the buckling portion 122 and the locking structure 201.

[0091] The limiting structure in this embodiment includes a protrusion 114 and a limiting groove 222. The protrusion 114 is arranged on the side of the installation body 511 close to the first installation part 22. The limiting groove 222 is arranged on the side of the first installation part 22 close to the installation body 511, and the protrusion 114 is abutted against the limiting groove 222 or moved out of the limiting groove 222 by an external force. In this embodiment, when the drum 30 is installed with the bracket 20, the protrusion 114 on the installation body 511 can be abutted against the limiting groove 222 of the first installation part 22, so as to further improve the assembly stability between the installation body 511 and the first installation part 22 during the rotation and movement of the drum 30, and prevent the buckle part 122 from deviating from the locking structure 201 due to the shaking of the installation body 511 under the rotation, rolling or movement of the drum 30.

[0092] Of course, the protrusion 114 in this embodiment can also be arranged on the side of the first mounting portion 22 close to the mounting body 511, and the limiting groove 222 is arranged on the side of the mounting body 511 close to the first mounting portion 22, and this embodiment does not make a sole limitation on this. Among them, the limiting groove 222 can be specifically arranged on the side of the opening groove 221 away from the pressing block 123 along the second direction, and the notch of the limiting groove 222 close to the pressing block 123 along the second direction is connected to the opening groove 221, which can not only reduce the processing difficulty of the limiting groove 222, but also improve the convenience and stability of operation when the buckle portion 122 is buckled with the locking structure 201. That is to say, when installing the drum 30 on the bracket 20, the protrusion 114 on the installation body 511 can be first moved into the limiting groove 222 along the second direction to initially position the locking body 512 connected to the installation body 511, and then the pressing block 123 can be pressed or pulled to make the buckling part 122 buckle with the locking structure 201. During this process, since the protrusion 114 is located in the limiting groove 222, the installation body 511 is not easy to deflect, which facilitates the quick and easy buckling of the buckling part 122 with the locking structure 201.

[0093] The cleaning body also includes a driving component 40, which is detachably connected to the end of the bracket 20 away from the first mounting portion 22 and at least partially penetrated into the drum 30, and the driving component 40 is used to drive the drum 30 to rotate around its own axis. The driving component 40 includes a disassembly and assembly portion 41, a bearing seat 42, a second bearing 43, a driving motor 44 and a connector 45. The cleaning body also includes a supporting component 52, which is at least partially penetrated on a side of the drum 30 close to the first mounting portion 22 and can rotate with the drum 30, and the supporting component 52 is rotatably connected to the mounting component 51. In the process of the drum 30 rotating along its own circumference under the drive of the driving component 40, since the supporting component 52 can rotate relative to the mounting component 51, the supporting component 52 will not interfere with the rotational movement of the drum 30 while supporting the drum 30, thereby ensuring the stability of the drum 30 during the rotation and movement process. Secondly, since the installation component 51 is buckled with the locking structure 201 on the first installation part 22 through the locking body 512, when the roller 30 needs to be replaced or maintained, the driving component 40 and the bracket 20 are disassembled, and the locking body 512 and the locking structure 201 are unlocked, and the roller 30 connected to the connecting head 45 of the driving component 40 can be removed to perform corresponding replacement or maintenance and repair work on the roller 30. After the roller 30 is removed, the installation component 51 and the supporting component 52 can be kept on the roller 30 without being removed, thereby avoiding the installation component 51 and the supporting component 52 from being accidentally lost, and when the roller 30 needs to be reinstalled on the bracket 20, there is no need to assemble the supporting component 52 and the installation component 51, and the installation component 51 can be buckled with the locking structure 201 on the bracket 20, which is convenient and efficient to operate.

[0094] In this embodiment, the operator only needs to press the pressing block 123 to separate the buckle 122 from the locking structure 201 to remove the roller 30 from the bracket 20, which is efficient and convenient. When the roller 30 needs to be installed on the bracket 20, after the roller 30 is connected to the driving component 40, the buckle 122 at the end of the roller 30 away from the driving component 40 is pressed into the buckle groove, and the buckle 122 is abutted against the buckle groove under the elastic tensile force of the elastic element 121.

[0095] like Fig. 9 As shown, the bracket 20 in this embodiment may specifically include a bracket body 21, a first mounting portion 22 and a second mounting portion 23, wherein the first mounting portion 22 and the second mounting portion 23 are respectively located at opposite ends of the bracket body 21 along the first direction. The bracket body 21 is an arc-shaped plate-like structure adapted to the outer surface of the drum 30, and the arc-shaped plate-like structure covers the drum 30 to improve the structural strength of the entire cleaning mechanism. The first mounting portion 22 and the second mounting portion 23 may both be plate-like structures integrally formed with the bracket body 21.

[0096] The driving component 40 of the cleaning body is detachably connected to the second mounting portion 23 and is located between the second mounting portion 23 and the first mounting portion 22. Specifically, the disassembly portion 41 of the driving component 40 can be connected to the second mounting portion 23 through a locking member such as a screw, and the disassembly is simple and convenient. Before the driving component 40 is connected to the second mounting portion 23, the roller 30 is sleeved on the driving component 40 so that the roller 30 can be moved along its own axial direction under the action of an external force to separate from the driving component 40. The mounting component 51 is connected to one end of the roller 30 close to the first mounting portion 22 through the supporting component 52. After the roller 30 is sleeved on the driving component 40, one end of the roller 30 close to the first mounting portion 22 can be buckled with the locking structure 201 on the first mounting portion 22 through the locking body 512 of the mounting component 51. When the roller 30 needs to be removed, after the driving component 40 is disassembled from the second mounting portion 23, the locking body 512 and the locking structure 201 are unlocked to remove the roller 30 from the bracket 20. If the removed roller 30 needs to be cleaned, the roller 30 can be pulled to move along its own axial direction until it is separated from the driving component 40. Of course, in this embodiment, the driving component 40 can also be directly connected to the first mounting portion 22 through the mounting component 51. In this case, a locking structure 201 can also be provided on the side of the first mounting portion 22 close to the driving component 40. After the driving component 40 is connected to the mounting body 511 of the mounting component 51, it is buckled with the locking structure 201 on the first mounting portion 22 through the locking body 512. When the roller 30 needs to be removed, it is only necessary to unlock and separate the locking body 512 at the driving component 40 and the locking body 512 at the end of the roller 30 away from the driving component 40 from the corresponding locking structure 201, which further improves the efficiency and convenience of disassembling the roller 30.

[0097] In an optional embodiment of the present invention, when the drum 30 does not need to be connected to the driving component 40 to rotate under the drive of the driving component 40, the mounting component 51 in this embodiment may include at least two, such as connecting the two mounting components 51 to the opposite ends of the drum 30 along its own axis. In this case, the first mounting portion 22 and the second mounting portion 23 of the bracket 20 are both provided with a locking structure 201 on one side close to the drum 30, and the opposite ends of the drum 30 along its own axis are both buckled with the locking structure 201 through the locking body 512 of the mounting component 51, and the disassembly and assembly are more efficient and convenient. At the same time, when the mounting components 51 at the opposite ends of the drum 30 along its own axis are rotatably connected to the drum 30 through the supporting components 52, since the supporting components 52 can rotate with the drum 30, when the drum 30 moves with the cleaning equipment, the friction of the drum 30 against the ground can drive the supporting components 52 to rotate, so that the drum 30 can roll and clean the ground without adding a driving component 40. Moreover, since the bracket 20 is usually connected to a wiper plate 24 that abuts against the outer peripheral surface of the drum 30, during the rolling process of the drum 30, the wiper plate 24 can also be used to scrape away dirty water from the drum 30, thereby enhancing the cleaning effect of the drum 30.

[0098] The support member 52 in this embodiment includes a connecting shaft 521 and a supporting body 522. The connecting shaft 521 is coaxially arranged with the drum 30, and one end of the connecting shaft 521 is connected to the mounting member 51 and can rotate around its own axis relative to the mounting member 51. The supporting body 522 is connected to the other end of the connecting shaft 521, and the supporting body 522 is at least partially arranged in the drum 30. After the mounting member 51 is connected with the bracket 20, since the connecting shaft 521 can rotate relative to the mounting member 51, when the drum 30 rotates, the supporting body 522 connected to the connecting shaft 521 can rotate with the drum 30, thereby improving the stability of the drum 30 during the rotation process, and when the drum 30 rotates, the mounting member 51 buckled with the bracket 20 will not interfere with the rotation of the drum 30. It can be seen that the support member 52 in this embodiment can not only stably support the drum 30, but also prevent the mounting member 51 from interfering with the normal operation of the drum 30, and the overall structure of the support member 52 is simple and stable, and the assembly efficiency between the supporting member 52 and the mounting member 51 is high.

[0099] like Figure 5As shown, the mounting body 511 in this embodiment includes a mounting seat 111 and a first bearing 113. A first avoidance hole 112 is provided on one side of the mounting seat 111 close to the connecting shaft 521, and the length of the first avoidance hole 112 extends along the first direction. The first bearing 113 is located in the first avoidance hole 112, and the outer peripheral surface of the first bearing 113 is connected to the inner wall surface of the first avoidance hole 112. The connecting shaft 521 is at least partially penetrated in the first avoidance hole 112 and connected to the inner peripheral surface of the first bearing 113. One end of the connecting shaft 521 away from the first avoidance hole 112 along the first direction is connected to the support body 522, and the locking body 512 is connected to the side of the mounting seat 111 close to the locking structure 201. Therefore, this embodiment connects the locking body 512 with the drum 30 by rotatably connecting the first bearing 113 installed in the mounting seat 111 with the connecting shaft 521 of the supporting component 52, so that the locking body 512 can buckle the drum 30 and the bracket 20 while avoiding interference of the locking body 512 with the rotation of the drum 30.

[0100] In this embodiment, the first bearing 113 may include at least two, such as two first bearings 113 are arranged side by side in the first avoidance hole 112 along the first direction and are respectively connected to the connecting shaft 521. The outer circumferences of the two first bearings 113 are connected to the inner wall surface of the first avoidance hole 112, and the inner circumferences are connected to the connecting shaft 521, thereby improving the assembly strength and rotation reliability between the connecting shaft 521 and the mounting seat 111.

[0101] Specifically, see Figure 8 , Fig.10 as well as Fig.11The mounting seat 111 in this embodiment includes a first mounting seat 1111 and a second mounting seat 1112. The first avoidance hole 112 is arranged in the first mounting seat 1111 along the first direction to make the processing of the first avoidance hole 112 more convenient. The second mounting seat 1112 is located on a side of the first mounting seat 1111 close to the locking structure 201 and is detachably connected to the first mounting seat 1111, and there is an installation gap between the second mounting seat 1112 and the connecting shaft 521 to prevent the second mounting seat 1112 from interfering with the rotation of the connecting shaft 521. The lock body 512 is connected to a side of the second mounting seat 1112 close to the locking structure 201. In this embodiment, the first mounting seat 1111 and the second mounting seat 1112 are connected to obtain the mounting seat 111 as a whole, and the first avoidance hole 112 is provided through the first mounting seat 1111, thereby improving the processing convenience of the mounting seat 111. During installation, a certain installation gap is provided between the second mounting seat 1112 and the connecting shaft 521, so that the mounting seat 111 will not interfere with the rotation of the connecting shaft 521 after being connected to the connecting shaft 521. The installation gap can be obtained by providing a groove on the side of the second mounting seat 1112 close to the connecting shaft 521, which is concave in the direction away from the connecting shaft 521, is easy to process, and can improve the assembly efficiency between the mounting seat 111 and the supporting component 52.

[0102] like Figure 6 As shown, the support body 522 is also provided with a second avoidance hole 5223, and the mounting seat 111 further includes a connecting protrusion 1113 and a connecting column 1114. The connecting protrusion 1113 is provided on a side of the first mounting seat 1111 close to the second mounting seat 1112, and a third avoidance hole 1131 is provided in the connecting protrusion 1113. The third avoidance hole 1131 penetrates the first mounting seat 1111 along the first direction and is connected to the second avoidance hole 5223. The connecting column 1114 is provided on a side of the second mounting seat 1112 close to the first mounting seat 1111, and the connecting column 1114 is penetrated in the third avoidance hole 1131 and connected to the first mounting seat 1111 through a locking member. When the support body 522 and the first mounting seat 1111 are assembled on the connecting shaft 521, the locking piece can be placed along the second avoidance hole 5223 at the third avoidance hole 1131 to fix the connecting column 1114 and the first mounting seat 1111, thereby improving the assembly efficiency and convenience between the second mounting seat 1112 and the first mounting seat 1111.

[0103] Since the first groove 523 is provided on one side of the support body 522 close to the mounting member 51, the second avoidance hole 5223 on the support body 522 can be specifically arranged to penetrate the groove bottom of the first groove 523 along the first direction, which is convenient for processing and does not affect the structural strength of the contact portion between the support body 522 and the drum 30. The mounting seat 111 of the mounting member 51 is located in the first groove 523, and the second avoidance hole 5223 can be connected with the third avoidance hole 1131 on the first mounting seat 1111 through the first groove 523. After the first mounting seat 1111 and the connecting shaft 521 are connected, when the first mounting seat 1111 and the second mounting seat 1112 need to be connected, the connecting column 1114 on the second mounting seat 1112 is inserted into the third avoidance hole 1131, and then the disassembly tool (such as a screwdriver) is extended into the first groove 523 along the second avoidance hole 5223 on the support body 522 to reach the third avoidance hole 1131, and the locking member (such as a screw) is screwed to fix it with the connecting column 1114 inserted in the third avoidance hole 1131. Specifically, when there are multiple second avoidance holes 5223, they can be arranged around the outer periphery of the connecting hole 2221 of the support body 522 along the circumferential direction of the support body 522. Since the support body 522 can drive the connecting shaft 521 to rotate relative to the first mounting seat 1111 along with the roller 30, whether the second avoidance hole 5223 is one or more, it is only necessary to rotate the support body 522 to make any second avoidance hole 5223 correspond to and connect with the third avoidance hole 1131, and then place the locking piece along the second avoidance hole 5223 at the third avoidance hole 1131 to fix the connecting column 1114 and the first mounting seat 1111, so that the assembly between the first mounting seat 1111 and the second mounting seat 1112 is convenient and efficient.

[0104] like Fig.11 As shown, in order to make the connection between the first mounting seat 1111 and the second mounting seat 1112 more firm and reliable, a plurality of connecting protrusions 1113 may be provided on the first mounting seat 1111, and a plurality of connecting columns 1114 may be provided on the second mounting seat 1112 accordingly, and the plurality of connecting protrusions 1113 and the plurality of connecting columns 1114 may be provided at intervals along the circumference of the first avoidance hole 112. At this time, the plurality of second avoidance holes 5223 provided on the support body 522 may be rotated to correspond to the plurality of third avoidance holes 1131 in the connecting protrusions 1113, respectively, so that the first mounting seat 1111 and the second mounting seat 1112 are connected together by a plurality of locking members at the same time, further improving the assembly efficiency between the first mounting seat 1111 and the second mounting seat 1112. The locking member in this embodiment may include at least one of a screw, a screw, a stud, etc.

[0105] like Figure 5As shown, the mounting component 51 in this embodiment further includes a stopper 514, which is disposed on the connecting shaft 521 and is located on the side of the first bearing 113 close to the second mounting seat 1112. The stopper 514 is used to restrict the first bearing 113 on the connecting shaft 521 to prevent the first bearing 113 from falling off the connecting shaft 521. The stopper 514 may specifically include an annular protrusion convexly disposed on the surface of the connecting shaft 521, such as a common snap ring, so that the first bearing 113 is restricted on the connecting shaft 521 by the snap ring sleeved on the connecting shaft 521 to prevent the first bearing 113 from falling off the connecting shaft 521, thereby improving the connection reliability between the support component 52 and the mounting component 51.

[0106] See also Fig.11 The mounting member 51 further includes a guide assembly 515, through which the pressing block 123 is connected to the mounting body 511. The guide assembly 515 is used to guide the pressing block 123 to move along the first direction, so as to prevent the pressing block 123 from shaking relative to the mounting body 511 due to deviation in the moving direction, thereby improving the stability and smoothness of the buckling and disassembly operations of the buckling portion 122 and the locking structure 201.

[0107] like Fig.11 As shown, the guide assembly 515 in this embodiment includes a first guide column 151 and a second guide column 152. The first guide column 151 includes at least two, and at least two first guide columns 151 are arranged at intervals on the side of the installation body 511 close to the lock body 512, and a first guide hole 1511 is arranged in the first guide column 151. The second guide column 152 includes at least two, and at least two second guide columns 152 are arranged at intervals on the side of the pressing block 123 away from the first installation portion 22 and are arranged one-to-one with the at least two first guide columns 151. The second guide column 152 is inserted into the first guide hole 1511 and can move relative to the first guide column 151 along the first direction. When pressing the pressing block 123, the second guide column 152 moves stably relative to the first guide column 151 along the first direction, thereby preventing the pressing block 123 from shaking or even deviating from the predetermined movement trajectory.

[0108] Specifically, Fig.11As shown, the first guide column 151 in this embodiment can be specifically arranged on a side of the second mounting seat 1112 close to the buckle portion 122. Specifically, the mounting groove 513 of the mounting body 511 is arranged on a side of the second mounting seat 1112 close to the first mounting portion 22. A plurality of first guide columns 151 are arranged at intervals along the circumference of the drum 30 at the bottom of the mounting groove 513. A first guide hole 1511 is arranged in the first guide column 151, and a guide rod 1512 is arranged in the first guide hole 1511. The outer diameter of the guide rod 1512 is smaller than the first guide hole 1511, and one end of the guide rod 1512 can be detachably locked in the first guide hole 1511 by a locking member such as a screw or a screw. A plurality of second guide posts 152 are arranged one-to-one corresponding to the first guide holes 1511 and are located on the pressing block 123. The outer diameter of the second guide posts 152 matches the inner diameter of the first guide holes 1511. A second guide hole is arranged inside the second guide posts 152. The inner diameter of the second guide hole matches the outer diameter of the guide rod 1512. When the second guide posts 152 are inserted into the first guide holes 1511, the second guide holes are inserted into the guide rod 1512 to further improve the stability of the second guide posts 152 when they move relative to the first guide posts 151. In the process of pressing or stretching the pressing block 123, the second guide posts 152 can be inserted into the guide rod 1512 of the first guide holes 1511 and reciprocated relative to the guide rod 1512 along the first direction to ensure that the pressing block 123 will not shake relative to the second mounting seat 1112 during the movement, thereby reducing the difficulty of buckling and unlocking between the buckling portion 122 and the locking structure 201. Specifically, at least two second guide posts 152 on the pressing block 123 are respectively connected to the side of at least two buckling parts 122 away from the first mounting part 22, and when the buckling parts 122 are buckled with or separated from the locking structure 201, the guiding force can be concentrated at the buckling parts 122 to improve the accuracy of the buckling parts 122 when they are buckled with or separated from the locking structure 201 under the action of the elastic element 121. It is prevented that the buckling parts 122 are difficult to buckle with or separate from the locking structure 201 due to shaking with the pressing block 123.

[0109] In addition, since the first guide column 151 and the second guide column 152 are both located in the installation groove 513, the structure of the installation component 51 is more compact and easy to assemble. In addition, the installation distance between the roller 30 and the first installation portion 22 will not be increased, ensuring that the roller 30 can perform edge cleaning when the cleaning device is extended to perform cleaning work. Therefore, in this embodiment, the guide assembly 515 guides the movement trajectory of the pressing block 123 so that the buckle portion 122 can be buckled or separated from the locking structure 201 stably and accurately.

[0110] The third embodiment of the present utility model further provides a cleaning device, which includes a body 10 and a cleaning mechanism. A storage cavity 11 is provided at the bottom of the body 10. The cleaning mechanism is installed in the storage cavity 11.
