[0067] Please see Figures 1-4 , Figure 1This is a schematic diagram of the structure of the mop mechanism 100 provided in the embodiments of this application. Figure 2 This is a schematic diagram of the internal structure of the mop mechanism 100 provided in an embodiment of this application; Figure 3 This is a schematic diagram of the mop mechanism 100 provided in this embodiment of the application when used to disassemble the cylindrical mop 4. Figure 4 This is a schematic diagram of the internal structure of the mop mechanism 100 when disassembling the cylindrical mop 4, as provided in this embodiment of the application. 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. See also... Figures 1-4 The X-axis represents the distribution direction of the driving roller 2 and the driven roller 3, the Y-axis represents the length extension direction of the mop mechanism 100, and the Z-axis represents the direction perpendicular to the cylindrical mop 4.

[0068] 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.

[0069] Please see Figure 2 The diagram 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, meaning that 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.

[0070] Please see Figure 2 The driving roller 2 and the driven roller 3 are arranged opposite each other; please refer to Figure 1 This illustrates that the cylindrical rag 4 is set outside the driving roller 2 and the driven roller 3.

[0071] In one example, the cylindrical cloth 4 is directly fitted over the drive roller 2 and the driven roller 3; in another example, please refer to [link to example]. Figure 1 The drive roller 2 and the driven roller 3 are covered with a conveyor belt 5, and the conveyor belt 5 is covered with a cylindrical wiping cloth 4. The conveyor belt 5 and the cylindrical wiping cloth 4 are either integrated or separate.

[0072] 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 is rotated by 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.

[0073] 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.

[0074] 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.

[0075] That is, when it is not necessary to replace the cylindrical mop 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 as follows. Figure 2 The parallel state is shown; when it is necessary to replace the tubular rag 4 on the mop mechanism 100, at least one end of the driven roller 3 should be adjusted to move closer to the driving roller 2 so as to remove the tubular rag 4.

[0076] For the driven roller 3, one end can be moved closer to the driving roller 2. Specifically, please refer to [link to relevant documentation]. Figure 1 , Figure 1 This diagram illustrates the structure of the mop mechanism 100 in its normal operating state. Under normal conditions, the driving roller 2 and the driven roller 3 are parallel, and the cylindrical mop 4 is taut. When the driving roller 2 rotates along its own axis, it drives the cylindrical mop 4 to rotate. (See also...) Figure 2 This illustrates that when the mop mechanism 100 is in its normal state, the driving roller 2 and the driven roller 3 are supported parallel to each other on the frame 1; please refer to [link to relevant documentation]. Figure 3 The diagram illustrates the state when the mop mechanism 100 is in the disassembled tubular mop 4 position. Please refer to [link / reference]. Figure 4 , Figure 4 correspond Figure 3 The positions of the driving roller 2 and the driven roller 3 on the frame 1, from Figure 4 As can be seen, 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 [link / reference]. Figure 3 With one end of the driven roller 3 close to the driving roller 2, the cylindrical cloth 4 is not in a taut state and moves along... Figure 3 In the direction indicated by the arrow on the Y-axis, the gap 20 between the driven roller 3 and the cylindrical cloth 4 increases. At this time, along... Figure 3 Pull the cylindrical cloth 4 outwards in the direction indicated by the arrow on the Y-axis to easily remove it.

[0077] 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.

[0078] 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.

[0079] The above describes the process of disassembling the cylindrical cleaning cloth 4. Regarding 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 on both 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 follows... Figure 4 The driven roller 3 is adjusted so that one end is close to the driving roller 2, and then the cylindrical cloth 4 is put onto the driven roller 3 and the driving roller 2 at the end of the driven roller 3 that is close to the driving roller 2, so as to facilitate the installation of the cylindrical cloth 4.

[0080] 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.

[0081] 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.

[0082] Please see Figure 2 The diagram illustrates the main frame 11 and the supporting section 12, as well as the elastic device 6 disposed between the main frame 11 and the supporting section 12. The elastic device 6 is preferably an elastic element made of spring or elastic rubber.

[0083] 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, which support the drive roller 2 on the frame body 11. Please refer to [link / reference]. Figure 2The diagram shows the input end 21 of the drive roller 2, which can be connected to an external drive device. When the external drive device is activated, it can drive the drive roller 2 to rotate.

[0084] Please see Figure 2 One end of the driven roller 3 is connected to the support body 12, and the driven roller 3 is rotatably connected to the support body 12. Please refer to [link / reference]. Figure 5 This is an exploded schematic diagram of the main frame 11 and the supporting components 12. Figure 5 The diagram shows that a bearing 30 is installed at one end of the driven roller 3, and the driven roller 3 is supported on the support body 12 by the bearing 30.

[0085] Please see Figure 5 This illustrates 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.

[0086] An elastic device 6 is installed between the main frame 11 and the supporting component 12. Under normal circumstances, please refer to [the relevant documentation / reference]. Figure 1 The drive roller 2 and driven roller 3 are covered by a conveyor belt 5 and a cylindrical rag 4. The elastic device 6 between the main frame 11 and the supporting sub-frame 12 is in a compressed state; please refer to the comparison. Figure 2 and Figure 4 When the supporting segment 12 moves closer to the frame body 11, it continues to compress the elastic device 6, causing the driven roller 3 to rotate relative to the frame body 11. The end of the driven roller 3 connected to the supporting segment 12 moves closer to the driving roller 2. When the force on the supporting segment 12 is released, the supporting segment 12 can be reset under the action of the elastic device 6.

[0087] In this embodiment, when it is necessary to remove the cylindrical rag 4, the supporting part 12 is pushed towards the main body 11 of the frame, and then along... Figure 3 The direction indicated by the Y-axis arrow pulls the cylindrical cloth 4 out a short distance. As the cylindrical cloth 4 is pulled out, it obstructs the support component 12, making it difficult to apply force to it. The force applied to the support component 12 can be released first. While continuing to pull the cylindrical cloth 4, as more of the driven roller 3 becomes exposed, it can be pushed closer to the driving roller 2, causing the support component 12 to move closer to the frame body 11. This facilitates pulling the cylindrical cloth 4 out further. When it is necessary to install the cylindrical cloth 4 on the driving roller 2 and the driven roller 3, please refer to [link to relevant documentation]. Figure 4 This can push the driven roller 3 close to the circumferential side of the support body 12, and put the cylindrical cloth 4 through the end of the support body 12 onto the driving roller 2 and the driven roller 3.

[0088] 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 ensures that when the force on the support segment 12 is removed, the driven roller 3 remains stationary under the action of the mating component. Figure 4 The tilted position shown is to facilitate the disassembly and installation of the cylindrical rag 4.

[0089] 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.

[0090] In an example where both ends of the driven roller 3 can move toward the driving roller 2, in one embodiment, please refer to... Figure 7 The frame 1 includes a frame body 11 and two supporting 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 supporting sections 12. An elastic device 6 is provided between each supporting section 12 and the frame body 11.

[0091] Please see Figure 7 The diagram illustrates 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 each of 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0148] In this embodiment, the limiting protrusion 81 of the through groove 1134 is blocked by the baffle plate 10 to prevent the limiting protrusion 81 located in the through groove 1134 from detaching from the frame body 11 through the first side 1131. Specifically, taking the first mounting groove 1135 as an example, please refer to... Figure 13 The diagram illustrates that a through groove 1134 is provided on the side wall of one end of the first mounting groove 1135 along the length of the frame body 11. Please refer to [link / reference]. Figure 14The diagram illustrates that a limiting groove 1133 is provided on the side wall of the other end of the first mounting groove 1135 along the length of the frame body 11. This limiting groove 1133 does not extend to the first side surface 1131. When installing the first support frame 85 into the first mounting groove 1135, first insert the limiting protrusion 81 at one end of the first support frame 85 into the limiting groove 1133 that does not extend to the first side surface 1131, and then insert the limiting protrusion 81 at the other end of the first support frame 85 into the through groove 1134 to facilitate the installation of the first support frame 85 in the first mounting groove 1135. Then, the blocking plate 10 is installed, which blocks the limiting protrusion 81 of the through groove 1134.

[0149] In this embodiment, a through groove 1134 is provided to facilitate the installation of the support frame 8 in the mounting groove 1132. A baffle plate 10 is provided to block the limiting protrusion 81 of the through groove 1134 to prevent the limiting protrusion 81 located in the through groove 1134 from detaching from the frame body 11 through the first side 1131, thereby limiting the support frame 8 on the frame body 11.

[0150] To facilitate the installation of the support frame 8 on the frame body 11, in one embodiment, the two limiting grooves 1133 opposite to the mounting groove 1132 are both through grooves 1134, one end of which opens to the first side 1131; the mop mechanism 100 also includes a baffle plate 10, which fits against the first side 1131 and is detachably connected to the frame body 11, with each through groove 1134 corresponding to a baffle plate 10, and the baffle plate 10 is used to block the limiting protrusion 81 located in the through groove 1134.
