[0053] Please refer to Figures 1-4. Figure 1 is a structural schematic diagram of the mop mechanism 100 provided in this embodiment of the present disclosure; Figure 2 is a structural schematic diagram of the internal structure of the mop mechanism 100 provided in this embodiment of the present disclosure; Figure 3 is a structural schematic diagram of the mop mechanism 100 provided in this embodiment of the present disclosure when used to disassemble the cylindrical wiping cloth 4; and Figure 4 is a structural schematic diagram of the internal structure of the mop mechanism 100 provided in this embodiment of the present disclosure when used to disassemble the cylindrical wiping cloth 4. Before describing the mop mechanism 100 provided in this embodiment, for ease of description, the following directional definitions are made: the mop mechanism 100 can be calibrated by the following three mutually perpendicular axes: the X-axis, the Y-axis, and the Z-axis. Referring to Figures 1-4, the X-axis is the direction in which the driving roller 2 and the driven roller 3 are distributed; the Y-axis is the length extension direction of the mop mechanism 100; and the Z-axis is the direction perpendicular to the cylindrical wiping cloth 4.

[0054] The mop mechanism 100 provided in this embodiment includes a frame 1, a drive roller 2, a driven roller 3, and a cylindrical mop 4.

[0055] Please refer to Figure 2, which illustrates that the driving roller 2 and the driven roller 3 are supported on the frame 1. Both the driving roller 2 and the driven roller 3 are rotatably connected to the frame 1, that is, the driving roller 2 can rotate relative to the frame 1 along its own axis, and the driven roller 3 can rotate relative to the frame 1 along its own axis.

[0056] Please refer to Figure 2, where the driving roller 2 and the driven roller 3 are arranged opposite each other; please refer to Figure 1, which shows the cylindrical rag 4 sleeved outside the driving roller 2 and the driven roller 3.

[0057] In one example, the cylindrical rag 4 is directly sleeved over the drive roller 2 and the driven roller 3; in another example, as shown in Figure 1, the drive roller 2 and the driven roller 3 are covered with a conveyor belt 5, and the cylindrical rag 4 is sleeved over the conveyor belt 5. The conveyor belt 5 and the cylindrical rag 4 are either integrated or separate.

[0058] In the example where the cylindrical rag 4 is directly fitted onto the drive roller 2 and the driven roller 3, when the drive roller 2 rotates under the drive of an external drive device, the drive roller 2 can drive the cylindrical rag 4 to rotate, and the rotation of the cylindrical rag 4 drives the driven roller 3 to rotate.

[0059] In the example where a conveyor belt 5 is provided over the drive roller 2 and the driven roller 3, and a cylindrical wiping cloth 4 is provided over the conveyor belt 5, when the drive roller 2 rotates under the drive of an external drive device, the drive roller 2 can drive the conveyor belt 5 and the cylindrical wiping cloth 4 to rotate synchronously, and the rotation of the conveyor belt 5 drives the driven roller 3 to rotate.

[0060] In this embodiment, at least one end of the driven roller 3 can move toward the driving roller 2. Specifically, one end of the driven roller 3 can be configured to move toward the driving roller 2, or both ends of the driven roller 3 can be configured to move toward the driving roller 2.

[0061] When it is not necessary to replace the cylindrical rag 4 on the mop mechanism 100, the driven roller 3 is not adjusted so that the driving roller 2 and the driven roller 3 remain in a parallel state as shown in Figure 2; when it is necessary to replace the cylindrical rag 4 on the mop mechanism 100, at least one end of the driven roller 3 is adjusted to move closer to the driving roller 2 so that the cylindrical rag 4 can be removed.

[0062] For the driven roller 3, one end can be moved closer to the driving roller 2. Specifically, please refer to Figure 1, which shows the structure of the mop mechanism 100 in its normal state. That is, under normal conditions, the driving roller 2 and the driven roller 3 are parallel, and the cylindrical wiping cloth 4 is in a tensioned state. When the driving roller 2 rotates along its own axis, the driving roller 2 can drive the cylindrical wiping cloth 4 to rotate. Please refer to Figure 2, which shows the driving roller 2 and the driven roller 3 supported parallel on the frame 1 when the mop mechanism 100 is in its normal state. Please refer to Figure 3, which shows the mop mechanism 100 in the state of disassembling the cylindrical wiping cloth. For a schematic diagram of state 4, please refer to Figure 4. Figure 4 corresponds to the positions of the driving roller 2 and the driven roller 3 on the frame 1 in Figure 3. As can be seen from Figure 4, one end of the driven roller 3 is close to the driving roller 2 and the driven roller 3 is inclined relative to the driving roller 2. Please refer to Figure 3. When one end of the driven roller 3 is close to the driving roller 2, the cylindrical cloth 4 is not in a taut state. Along the direction indicated by the Y-axis arrow in Figure 3, the gap 20 between the driven roller 3 and the cylindrical cloth 4 increases. At this time, the cylindrical cloth 4 can be easily removed by pulling it outward along the direction indicated by the Y-axis arrow in Figure 3.

[0063] When both ends of the driven roller 3 can move towards the driving roller 2, if it is necessary to remove the cylindrical cloth 4, the two ends of the driven roller 3 can be adjusted to move towards the driving roller 2 so that the cylindrical cloth 4 is not in a tensioned state, making it easier to pull the cylindrical cloth 4 outward along the length of the mopping mechanism 100, so as to facilitate the removal of the cylindrical cloth 4.

[0064] In the prior art, the tubular cloth 4 is usually replaced when the driving roller 2 and the driven roller 3 are parallel and the tubular cloth 4 is in a taut state, which is very inconvenient to operate. In this embodiment, by adjusting at least one end of the driven roller 3 to move closer to the driving roller 2, the driven roller 3 does not press against the tubular cloth 4 to release the taut state of the tubular cloth 4, so that the tubular cloth 4 can be easily removed.

[0065] The above describes the process of disassembling the cylindrical cleaning cloth 4. For the installation of the cylindrical cleaning cloth 4, by setting at least one end of the driven roller 3 to move closer to the driving roller 2, it is also convenient to install the cylindrical cleaning cloth 4 onto the driving roller 2 and the driven roller 3. Taking the example that one end of the driven roller 3 can move closer to the driving roller 2, when it is necessary to install the cylindrical cleaning cloth 4, as shown in Figure 4, adjust one end of the driven roller 3 closer to the driving roller 2, and then place the cylindrical cleaning cloth 4 onto the driven roller 3 and the driving roller 2 at the end of the driven roller 3 that is closer to the driving roller 2, which facilitates the installation of the cylindrical cleaning cloth 4.

[0066] The mop mechanism 100 provided in this embodiment allows for easy removal of the cylindrical rag 4 by adjusting at least one end of the driven roller 3 towards the drive roller 2 when disassembling the rag 4. This ensures the rag 4 is not under tension. When assembling the rag 4 onto the drive roller 2 and the driven roller 3, at least one end of the driven roller 3 can be adjusted towards the drive roller 2, and the end of the driven roller 3 near the drive roller 2 will cover the rag 4 onto the driven roller 3 and the drive roller 2, facilitating the installation of the rag 4. In other words, the mop mechanism 100 provided in this embodiment can improve the replacement efficiency of the cylindrical rag 4.

[0067] In an example where one end of the driven roller 3 can move toward the driving roller 2, in one embodiment, the frame 1 includes a frame body 11 and a support section 12. The two ends of the driving roller 2 are rotatably connected to the frame body 11, one end of the driven roller 3 is hinged to the frame body 11, and the other end of the driven roller 3 is rotatably connected to the support section 12. An elastic device 6 is provided between the frame body 11 and the support section 12.

[0068] Please refer to Figure 2, which illustrates the frame body 11 and the supporting section 12, and shows the elastic device 6 disposed between the frame body 11 and the supporting section 12. The elastic device 6 is preferably an elastic element made of spring or elastic rubber.

[0069] Both ends of the drive roller 2 are rotatably connected to the frame body 11. Preferably, bearings are provided at both ends of the drive roller 2 to support the drive roller 2 on the frame body 11. Please refer to Figure 2, which shows the input end 21 of the drive roller 2. The input end 21 can be connected to an external drive device. When the external drive device is activated, it can drive the drive roller 2 to rotate.

[0070] Please refer to Figure 2. One end of the driven roller 3 is connected to the support segment 12. The driven roller 3 and the support segment 12 are rotatably connected. Please refer to Figure 5, which is an exploded view of the frame body 11 and the support segment 12. Figure 5 shows that a bearing 30 is set at one end of the driven roller 3. The driven roller 3 is supported on the support segment 12 through the bearing 30.

[0071] Please refer to Figure 5, which shows that the other end of the driven roller 3 is connected to the frame body 11. Since the driven roller 3 is hinged to the frame body 11, the driven roller 3 can rotate relative to the frame body 11.

[0072] An elastic device 6 is installed between the main frame 11 and the supporting section 12. Under normal circumstances, as shown in Figure 1, the drive roller 2 and the driven roller 3 are covered by a conveyor belt 5 and a cylindrical cloth 4, and the elastic device 6 between the main frame 11 and the supporting section 12 is in a compressed state. Referring to Figures 2 and 4, when the supporting section 12 moves closer to the main frame 11, it continues to compress the elastic device 6, causing the driven roller 3 to rotate relative to the main frame 11. The end of the driven roller 3 connected to the supporting section 12 moves closer to the drive roller 2. When the force on the supporting section 12 is released, the supporting section 12 can be reset under the action of the elastic device 6.

[0073] In this embodiment, when it is necessary to remove the cylindrical rag 4, push the support segment 12 towards the main body 11 of the frame, and then pull the cylindrical rag 4 out a section along the direction indicated by the Y-axis arrow in Figure 3. As the cylindrical rag 4 is pulled out, it obstructs the support segment 12, making it difficult to apply force to the support segment 12. The force applied to the support segment 12 can be canceled first. During the process of continuing to pull the cylindrical rag 4, as the exposed part of the driven roller 3 gradually increases, the driven roller 3 can be pushed towards the active roller 2, so that the support segment 12 moves towards the main body 11 of the frame, so that it is easier to pull the cylindrical rag 4 out when continuing to pull it. When it is necessary to install the cylindrical rag 4 on the active roller 2 and the driven roller 3, please refer to Figure 4. The driven roller 3 can be pushed towards the circumferential side of the support segment 12, and the cylindrical rag 4 can be sleeved onto the active roller 2 and the driven roller 3 through the end provided with the support segment 12.

[0074] In one example, the mop mechanism 100 also includes a mating component. After the support segment 12 is pushed towards the frame body 11 and into place, the mating component connects the support segment 12 and the frame body 11, or connects the support segment 12 and the input end 21 of the drive roller 2. This allows the driven roller 3 to maintain an inclined state as shown in Figure 4 under the action of the mating component when the force on the support segment 12 is removed, so as to facilitate the disassembly and installation of the cylindrical mop 4.

[0075] The structure of the frame 1 and the connection method between the active roller 2 and the driven roller 3 and the frame 1 provided in this embodiment not only enable one end of the driven roller 3 to move closer to the active roller 2, but also have a simple structure and make it easy and convenient to adjust the movement of one end of the driven roller 3 closer to the active roller 2. In addition, in the example where the mop mechanism 100 also includes a mating part, the use of the mating part makes it easier to disassemble and install the cylindrical mop 4.

[0076] In an example where both ends of the driven roller 3 can move toward the driving roller 2, in one embodiment, as shown in FIG7, the frame 1 includes a frame body 11 and two support sections 12. The two ends of the driving roller 2 are rotatably connected to the frame body 11, and the two ends of the driven roller 3 are rotatably connected to the corresponding support sections 12. An elastic device 6 is provided between each support section 12 and the frame body 11.

[0077] Please refer to Figure 7, which shows that the two ends of the driven roller 3 are connected to the corresponding support segments 12, and that elastic devices 6 are provided between the two support segments 12 and the frame body 11. The elastic device 6 is preferably an elastic element made of spring or elastic rubber.

[0078] Under normal circumstances, the drive roller 2 and driven roller 3 are covered by a conveyor belt 5 and a cylindrical rag 4, and the elastic device 6 between the frame body 11 and the support segment 12 is in a compressed state. When the two support segments 12 move towards the frame body 11, they continue to squeeze the corresponding elastic device 6, and both ends of the driven roller 3 move towards the drive roller 2. When the force on the support segment 12 is removed, the support segment 12 can be reset under the action of the elastic device 6.

[0079] In this embodiment, when it is necessary to remove the cylindrical rag 4, push the two support segments 12 towards the main body 11 of the frame, and then pull the cylindrical rag 4 outward from one end. As the cylindrical rag 4 is pulled out, it blocks one of the support segments 12, making it inconvenient to apply force to the support segment 12. The force applied to the support segment 12 can be canceled first. As the cylindrical rag 4 continues to be pulled, the driven roller 3 gradually becomes more exposed, and the driven roller 3 can be pushed towards the driving roller 2. When it is necessary to install the cylindrical rag 4 on the driving roller 2 and the driven roller 3, the driven roller 3 can be pushed towards the circumferential side of the support segment 12, and the cylindrical rag 4 can be looped onto the driving roller 2 and the driven roller 3 through one end of the main body 11 of the frame.

[0080] In one example, the mop mechanism 100 also includes a mating component. After the support segment 12 is pushed towards the frame body 11 and into place, the mating component connects the support segment 12 and the frame body 11. This allows the driven roller 3 to remain close to the driving roller 2 under the action of the mating component when the force on the support segment 12 is removed, so as to facilitate the disassembly and installation of the cylindrical mop 4.

[0081] The structure of the frame 1 provided in this embodiment, as well as the connection method between the active roller 2 and the driven roller 3 and the frame 1, not only allows both ends of the driven roller 3 to move towards the active roller 2, but also has a simple structure and makes it convenient to adjust one end of the driven roller 3 to move towards the active roller 2. In addition, in the example where the mop mechanism 100 also includes a mating part, the use of the mating part makes it easier to disassemble and install the cylindrical mop 4.

[0082] Regarding the cooperation relationship between the frame body 11 and the support sub-body 12, in one embodiment, one of the frame body 11 and the support sub-body 12 forms a guide groove 1121 and the other forms a guide protrusion 121. The guide protrusion 121 is located in the guide groove 1121, and the length extension direction of the guide groove 1121 is along the distribution direction of the driving roller 2 and the driven roller 3.

[0083] Please refer to Figures 2 and 4, which illustrate that a guide groove 1121 is formed on the main frame 11, and a guide protrusion 121 is formed on the supporting sub-body 12. The distribution direction of the driving roller 2 and the driven roller 3 is the direction of the X-axis in Figures 2 and 4, and the length extension direction of the guide groove 1121 is along the direction of the X-axis in Figures 2 and 4. When the supporting sub-body 12 is pushed towards the main frame 11, the guide protrusion 121 moves within the guide groove 1121 to guide the movement direction of the supporting sub-body 12.

[0084] In this embodiment, a guide groove 1121 is formed in one of the frame body 11 and the support part 12, and a guide protrusion 121 is formed in the other, which can guide the movement of the support part 12 and facilitate the stability of the support part 12 during operation.

[0085] In an example where a guide protrusion 121 is formed on the support segment 12, please refer to FIG5. In one embodiment, the support segment 12 further includes a segment main body 122 and a segment connecting part 123.
