The terms "first," "second," and similar terms used in the present patent application specification and claims do not denote any order, quantity, or importance, but are merely used to distinguish different components. Similarly, terms such as "a" or "an" do not denote a limitation of quantity, but rather denote the presence of at least one.

[0065] like Figures 1 to 13 FIG. 1 is a preferred embodiment of the present invention.

[0066] See also Figures 1 to 13 The mop device 100 provided in this embodiment includes a mop body 20, a cloth box device 30 and a driving device 40; the cloth box device 30 includes a cloth box mounting frame 31, a supply shaft 32 for carrying a roll of cleaning cloth 200 to be used, a recovery shaft 33 for recovering the used cleaning cloth 200, and a cleaning bracket 34 supported on the cloth box mounting frame 31 and used to load the cleaning cloth 200, the supply shaft 32 and the recovery shaft 33 are respectively rotatably supported on the cloth box mounting frame 31; the mop body 20 has an inner cavity 21, a placement opening 22 for the cloth box mounting frame 31 to slide into and out of the inner cavity 21, and a cleaning opening 23 through which the cleaning bracket 34 extends out of the inner cavity 21; the driving device 40 includes a transmission mounting plate 101 fixedly connected to the mop body 20, and a driving assembly 41 provided on the transmission mounting plate 101 and used to drive the recovery shaft 33 to rotate.

[0067] The above-mentioned mop device 100 can slide the cloth box mounting frame of the cloth box device into and out of the inner cavity through the access opening, so the mop can be easily replaced and the manual maintenance cost is low.

[0068] See also Figures 1 to 4 In the mop device 100 provided in this embodiment, the mop body 20 supports the mop body 20 and the driving device 40, the cloth box device 30 is slidably connected to the mop body 20, and the driving device 40 enables the cloth box device 30 to work.

[0069] See also Figures 1 to 6 The mop body 20 has an inner cavity 21, an access opening 22 through which a cloth supply box mounting bracket 31 slides in and out of the inner cavity 21, and a cleaning opening 23 through which a cleaning bracket 34 extends from the inner cavity 21. In this embodiment, the mop body 20 is generally in the shape of a rectangular box. The access opening 22 is located on the right side of the mop body 20 (the right side in the figure), and the cleaning opening 23 is located on the lower side of the mop body 20 (the lower side in the figure). A door panel 24 is connected to the cleaning opening 23. The door panel 24 is pivotally attached to the mop body 20 via a hinge. It is easy to understand that the door panel 24 can be opened to access and maintain the cloth box device 30, thereby facilitating the installation, replacement, and maintenance of the cloth box device 30.

[0070] In this embodiment, the mop body 20 is provided with a lifting bracket 25 and a lifting joint 26 for connecting to an external lifting motor (not shown). The lifting bracket 25 has a mounting hole 251 for an external rotating shaft (not shown) to pass through. It is worth noting that the lifting joint 26 will be connected to the lifting motor of the intelligent cleaning robot. The entire mop device 100 can be mounted on the rotating shaft of the intelligent cleaning robot body through the mounting hole 251 of the lifting bracket 25. The lifting motor acts on the lifting joint 26 to control the lifting and lowering of the entire mop device 100.

[0071] See also Figure 2 、 3 , 7 to 10, the drive device 40 includes a transmission mounting plate 101 fixedly connected to the mop body 20, and a drive assembly 41 disposed on the transmission mounting plate 101. In this embodiment, the transmission mounting plate 101 is fixedly mounted within the inner cavity 21 of the mop body by screws, dividing the inner cavity 21 into a first cavity 211 and a second cavity 212. The cloth box mounting frame 31 is disposed within the first cavity 211. The drive assembly 41 includes a driving pulley 411, a driven pulley 412, a transmission belt 413 wrapped therebetween, a drive motor 414 that rotates the driving pulley 411, and a drive shaft 415. The drive shaft 415 is keyed to the driven pulley 412. The transmission belt 413 is, but is not limited to, a synchronous belt, and the driving pulley 411 and the driven pulley 412 are, but are not limited to, synchronous pulleys. The driving device 40 also includes a rotary tensioning assembly 10, which includes a tensioning shaft 102 rotatably mounted on a transmission mounting plate 101. The transmission mounting plate 101 has a first side 101a facing the cloth box mounting frame 31 (i.e., located in the first cavity 211) and a second side 101b opposite to the first side 101a. The driving wheel 411, the driven wheel 412, and the transmission belt 413 are located on the second side 101b. In particular, the driving motor 414 is located outside the mop body 20. In this way, the cloth box device 30 is installed in the first cavity 211, and the driving wheel 411, the driven wheel 412, and the transmission belt 413 of the driving device 40 are arranged in the second cavity 212, which can prevent moisture and dust in the first cavity 211 from entering the second cavity 212 and affecting the service life of the components.

[0072] from Figure 7 and 8, a motor mounting plate 416 is provided on the second side 101b of the transmission mounting plate 101, and the drive motor 414 is fixedly mounted on the motor mounting plate 416 by fasteners; an adjustment block 417 is provided on the second side 101b of the transmission mounting plate 101, and the adjustment block 417 is fixedly mounted on the transmission mounting plate 101 by screws, and an adjusting screw (not shown in the figure) is provided on the adjustment block 417, and the adjustment block 417 is threadedly connected to the adjusting screw, and one end of the adjusting screw is abutted against the motor mounting plate 416; an adjustment hole 418 extending in a direction parallel to the axial direction of the adjusting screw is provided on the motor mounting plate 416, and a locking hole (not shown in the figure) corresponding to the adjustment hole 418 is provided on the transmission mounting plate 101. In this way, by turning the adjusting screw, the adjusting screw can be moved back and forth, thereby pushing the motor mounting plate 416 to move. In this way, the tightness of the synchronous belt can be adjusted by the adjusting screw on the adjusting block 417 to avoid the synchronous belt jumping teeth due to excessive looseness of the synchronous belt, thereby affecting the transmission effect.

[0073] Please continue to see Figure 9 and 10 The rotary tensioning assembly 10 of this embodiment further includes a tensioning gear 103 and a limiting structure. The tensioning gear 103 is sleeved on the tensioning shaft 102 and can rotate relative to the tensioning shaft 102. The limiting structure is used to limit the rotation of the tensioning gear 103 and the tensioning shaft 102. A damper 104 is provided on the transmission mounting plate 101. The damper 104 includes a damping gear that meshes with the tensioning gear 103. In this embodiment, a tensioning bearing seat 105 is removably fixed to the transmission mounting plate 101 by screws. A first tensioning bearing 106 is disposed within the tensioning bearing seat 105. The number of first tensioning bearings 106 is, but is not limited to, two, and the two first tensioning bearings 106 are spaced apart. The tensioning shaft 102 is mounted on the tensioning bearing seat 105 via the first tensioning bearings 106, with its ends extending beyond the ends of the tensioning bearing seat 105. The tensioning gear 103 is rotatably provided on the tensioning shaft 102, and the damper 104 is removably fixed to the transmission mounting plate 101 by screws, and the damping gear of the damper 104 cooperates with the tensioning gear 103 by meshing. It can be understood that when the tensioning shaft 102 rotates, it drives the tensioning gear 103 to rotate together with it by virtue of the restriction of the limiting structure, and the tensioning gear 103 will cause the damping gear of the damper 104 meshing with it to rotate, thereby forming a certain resistance to the rotation of the tensioning shaft 102, and maintaining a stable output. When the cloth is too loose, the device will automatically tighten the cloth and has a damping effect, which can avoid the phenomenon that the transmission cloth is too loose due to the free rotation of the tensioning shaft 102 or the transmission material is accumulated due to the fast supply speed.

[0074] Please continue to see Figure 9 and 10The limiting structure includes a rotation limiting plate 107 mounted on the tensioning shaft 102, a stopper mounting member 108 connected and fixed to the tensioning gear 103, and a stopper 109 fixed to the stopper mounting member 108. The rotation limiting plate 107 has a limiting portion 1071, which is used to abut against the stopper 109 and drive the tensioning gear 103 to rotate when the tensioning shaft 102 rotates. In this embodiment, the stopper mounting member 108 has a circular cross-section and is mounted on the tensioning shaft 102 and can rotate relative to the tensioning shaft 102. The stopper mounting member 108 is fixed to the tensioning gear 103 by screws, and the stopper 109 is screwed to the outer periphery of the stopper mounting member 108, and the stopper 109 extends toward the rotation limiting plate 107 along the axial direction of the tensioning shaft 102. The tensioning shaft 102 and the rotation limit plate 107 are connected in a non-rotatable manner. The tensioning shaft 102 has a non-circular anti-rotation portion, and the rotation limit plate 107 has an anti-rotation hole that matches the shape of the anti-rotation portion. The limit portion 1071 is formed from the outer edge of the rotation limit plate 107 and protrudes outward along the radial direction of the tensioning shaft 102. It can be understood that the tensioning shaft 102 can rotate independently of the stopper mounting member 108 and the tensioning gear 103. When the side wall of the limit portion 1071 of the rotation limit plate 107 installed on the tensioning shaft 102 abuts against the stopper 109, the rotation limit plate 107 drives the stopper mounting member 108 and the tensioning gear 103 to rotate together with the rotation of the tensioning shaft 102.

[0075] See also Figure 9 and 10 In this embodiment, a return spring 110 is sleeved on the tensioning shaft 102. One end of the return spring 110 is connected to the stopper mounting member 108, and the other end is connected to the rotation limit plate 107. It should be noted that when the rotation limit plate 107 is in the initial position, it does not contact the stopper 109, and the return spring 110 does not elastically deform. As the tensioning shaft 102 rotates, the rotation limit plate 107 rotates from the initial position to the position in contact with the stopper 109. At this time, the return spring 110 is in a torsional state. The return spring 110 has a certain torsional force, which can give the tensioning shaft 102 a certain pre-tightening force, thereby ensuring the stability of the mechanism. When the tensioning shaft 102 reverses, the torsional state of the return spring 110 has a certain compensatory effect on the reverse rotation of the tensioning shaft 102. In this way, the device has the advantages of simple structure, low cost, and high reliability.

[0076] See also Figure 9 and 10In this embodiment, the tensioning gear 103 is mounted on the tensioning shaft 102 via a second tensioning bearing 111. A limit ring (not shown) is provided on the tensioning shaft 102 to restrict axial movement of the second tensioning bearing 111. One end of the tensioning gear 103 abuts against the tensioning shaft 102, while the other end abuts against the limit ring, thereby limiting and securing the tensioning gear 103 in the axial direction. Furthermore, a stopper mounting member 108 is fixedly connected to the tensioning gear 103, further limiting its axial position.

[0077] See also Figure 9 and 10 In this embodiment, a locking bolt 113 is provided at the end of the tensioning shaft 102 to prevent the limiting structure from detaching from the tensioning shaft 102. A hole for inserting and removing the locking bolt 113 is opened on the end of the tensioning shaft 102. The locking bolt 113 is used to fix the rotation limiting plate 107 in the axial direction. This structure is convenient for disassembly and assembly.

[0078] See also Figures 1 to 4 As well as 11 to 13, the cloth box device 30 includes a cloth box mounting frame 31, a supply shaft 32 for carrying a rolled cloth formed by winding the cleaning cloth 200 to be used, a recovery shaft 33 for recovering the used cleaning cloth 200, and a cleaning bracket 34 supported on the cloth box mounting frame 31 and used for loading the cleaning cloth 200. The supply shaft 32 and the recovery shaft 33 are respectively rotatably supported on the cloth box mounting frame 31, and the recovery shaft 33 is connected to the driving assembly 41 and is driven to rotate by the driving assembly 41. In this embodiment, the supply shaft 32 and the recovery shaft 33 are parallel to each other. A first supply transmission shaft 311, coaxial with and connected to the supply shaft 32, and a first recovery transmission shaft 312, coaxial with and connected to the recovery shaft 33, are provided on the cloth box mounting frame 31. A second supply transmission shaft 313 and a second recovery transmission shaft 314 are provided on the cloth box mounting frame 31. The second supply transmission shaft 313 is connected to the supply shaft 32 at an end opposite to the first supply transmission shaft 311, while the second recovery transmission shaft 314 is connected to the recovery shaft 33 at an end opposite to the first recovery transmission shaft 312. A guide rail member 27 is provided within the mop body 20, and a slider member 315 is provided on the cloth box mounting frame 31 to slide with the guide rail member 27. The guide rail member 27 is connected to the cloth box mounting frame 31 through the slider member 315, so that the cloth box mounting frame 31 can slide on the guide rail member 27 to facilitate the removal of the cloth box mounting frame 31 from the mop body 20, thereby facilitating the replacement and maintenance of the cloth roll of the cloth box device 30.

[0079] Specifically, the supply shaft 32 is connected to a first supply transmission shaft 311 at one end and to a second supply transmission shaft 313 at the other end. The first and second supply transmission shafts 311, 313 are connected to the first supply transmission shaft 311 via a tight fit or keyed connection. The supply shaft 32 is hollow, and the first and second supply transmission shafts 311, 313 are embedded within the supply shaft 32. The first supply transmission shaft 311 is supported on the cloth box mounting frame 31 via a first supply bearing 316, while the second supply transmission shaft 313 is supported on the cloth box mounting frame 31 via a second supply bearing 317. The recovery shaft 33 is connected to a first recovery transmission shaft 312 at one end and to a second recovery transmission shaft 314 at the other end. The first and second recovery transmission shafts 312, 314 are connected to the first recovery transmission shaft 312 via a tight fit or keyed connection. The recovery shaft 33 is hollow, and the first and second recovery transmission shafts 312, 314 are embedded within the recovery shaft 33. The first recovery transmission shaft 312 is supported on the cloth box mounting frame 31 via a first recovery bearing 318, and the second recovery transmission shaft 314 is supported on the cloth box mounting frame 31 via a second recovery bearing 319. The first supply transmission shaft 311 is non-rotatably connected to the tensioning shaft 102, and the first recovery transmission shaft 312 is non-rotatably connected to the driving shaft 415. It is understood that when the driving shaft 415 rotates, the recovery shaft 33 is driven to rotate via the first recovery transmission shaft 312, and the recovery shaft 33 pulls the cleaning cloth 200 to move, thereby driving the supply shaft 32 to rotate. The cleaning cloth 200 moved to the cleaning bracket 34 can then clean and wipe the area to be cleaned.

[0080] In this embodiment, a driving key pin (not shown) is provided on the driving shaft 415, and a driving key slot (not shown) is provided at the end of the first recovery transmission shaft 312, into which the driving key pin slides, and a driving shaft slot 3121 is provided for the driving shaft 415 to slide into and communicate with the driving key slot. A tensioning key pin 1021 is provided on the tensioning shaft 102, and a tensioning key slot (not shown) is provided at the end of the first supply transmission shaft 311, into which the tensioning key pin 1021 slides, and a tensioning shaft slot 3111 is provided for the tensioning shaft 102 to slide into and communicate with the tensioning key slot. Thus, after the driving shaft 415 is docked with the driving shaft slot 3121 of the first recovery transmission shaft 312, the driving key pin and the driving key slot cooperate to transmit circumferential force to the first recovery transmission shaft 312 when the driving shaft 415 rotates, thereby driving the first recovery transmission shaft 312 and the recovery shaft 33 to rotate. Similarly, after the tensioning shaft 102 is docked with the tensioning shaft groove 3111 of the first supply transmission shaft 311, the tensioning key pin 1021 cooperates with the tensioning key groove, and when the supply shaft 32 drives the first supply transmission shaft 311 to rotate, the circumferential force is transmitted to the tensioning shaft 102 to drive the tensioning shaft 102 to rotate.

[0081] from Figure 3 、 9It can be seen that the axial length of the driving shaft 415 extending beyond the first side 101a is greater than the axial length of the tensioning shaft 102 extending beyond the first side 101a, that is, the shaft length of the driving shaft 415 located on the first side 101a of the transmission mounting plate 101 is longer than the shaft length of the tensioning shaft 102 located on this side. When installing the cloth box device 30, the position of the driving key pin of the driving shaft 415 can be positioned first, and then the position of the tensioning key pin 1021 of the tensioning shaft 102 can be positioned. This design facilitates the installation of the cloth box device 30 and avoids the need to simultaneously position the positions of the driving shaft 415 and the tensioning shaft 102, making operation simple and convenient.

[0082] See also Figure 3 、 11 13, the second supply transmission shaft 313 is connected to the supply adjustment handle 320, and the second recovery transmission shaft 314 is connected to the recovery adjustment handle 321. It is easy to understand that by operating the supply adjustment handle 320 and the recovery adjustment handle 321, the cloth can be manually tightened, which facilitates the installation and maintenance of the cloth.

[0083] See also Figure 1 、 3 , 5, 6, 11 to 13, the cloth box mounting frame 31 includes a frame body having a maintenance opening 31a and a maintenance side panel 322 that can open and close the maintenance opening 31a. The maintenance side panel 322 is removably connected to the frame body by butterfly screws. The second supply transmission shaft 313 and the second recovery transmission shaft 314 are respectively supported on the maintenance side panel 322. A locking pin 28 is provided in the mop body 20. A pin hole (not shown) is provided on the frame body for the locking pin 28 to pass through and to cooperate with the locking pin 28 for positioning. A lock buckle is provided on the frame body to secure the locking pin 28. In particular, the maintenance side panel 322 and the supply adjustment handle 320, recovery adjustment handle 321, second supply bearing 317, second recovery bearing 319, and bearing seat mounted thereon constitute the cloth box movable side panel assembly. When the butterfly screws are removed, the components can be removed separately, facilitating the installation and maintenance of the cloth roll. In addition, the locking pin 28 passes through the pin hole of the cloth box frame to position and fix the cloth box device 30 and strengthen the structural strength of the mop body 20.

[0084] As a further optimization, Figure 4 and 6 It can be seen that the mop body 20 is provided with a color mark sensor 29 in the inner cavity 21, which is used to detect the mark on the rolled cloth, mainly to detect the color mark of the rolled cloth on the recovery shaft 33, and identify whether the rolled cloth needs to be replaced. If no mark is detected, it means that the rolled cloth can continue to be used. If a mark is detected, it means that the rolled cloth needs to be replaced, and a signal can be sent to the background or the next operation can be executed.

[0085] See also Figure 3 、4 , 11 to 13, the cleaning bracket 34 is movably connected to the cloth box mounting frame 31. The cleaning bracket 34 includes a pressure roller assembly, which includes at least two pressure rollers 341 that abut the inner surface of the cleaning cloth 200. In this embodiment, the pressure rollers 341 of the pressure roller assembly are rotatably supported on the cleaning bracket 34. The cleaning bracket 34 and the cloth box mounting frame 31 are movably connected using any existing movable connection method, thereby enabling the cleaning bracket 34 to move forward, backward, left, right, and up and down, ensuring that the rolled cloth is always in close contact with the work surface. This improves the adaptability of the mopping device 100 to complex work surfaces and greatly enhances the cleaning efficiency of the mopping device 100.
