[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0049] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0050] The utility model provides a transmission mechanism which is used for assembling a ring-shaped mop which is connected end to end.

[0051] Reference Figures 1 to 4 In this embodiment, the transmission mechanism includes a mounting bracket 100 and three rotating rollers (210 and 220 in the figure respectively); the rotating rollers are used to be inserted in the area surrounded by the mop 300, and the three rotating rollers are parallel to each other and distributed in a triangular position, that is, the three rotating rollers are respectively arranged at the three corners of a triangle; the three rotating rollers are all rotatably arranged on the mounting bracket 100, that is, each rotating roller can rotate around its own axis relative to the mounting bracket 100. When the three rotating rollers are in their respective working positions, the three rotating rollers jointly tension the mop 300, so that the mop 300 is in a triangular prism shape (that is, the mop 300 is tensioned in a triangular crawler shape); at this time, by driving one of the rotating rollers to rotate, the rotating roller will drive the mop 300 to move around the three rotating rollers through friction, and the mop 300 will then drive the other two rotating rollers to rotate through friction, so that the mop 300 can clean the surface of the contacted object.

[0052] In this embodiment, at least one of the three rotating rollers is an adjustable rotating roller, and the adjustable rotating roller can be moved and switched between its working position and its first position, that is, the position of the adjustable rotating roller can be moved and adjusted. Figures 1 to 4 ,in Figure 1 and Figure 3 It is the state diagram of the three rotating rollers in their respective working positions. Figure 2 and Figure 4It is a state diagram of an adjustable rotating roller (i.e., 210 in the figure) in its first position; the sum of the distances from the working position of any adjustable rotating roller to the working positions of the remaining rotating rollers is greater than the sum of the distances from the first position of any adjustable rotating roller to the working positions of the remaining rotating rollers; that is, when any adjustable rotating roller moves from its working position to its corresponding first position, the perimeter of the triangle formed by the three rotating rollers will become smaller, so that the rotating rollers no longer tension the mop 300, and the mop 300 is in a relaxed state; when the adjustable rotating roller moves from its first position back to its working position, the three rotating rollers tension the mop 300 together, so that the mop 300 returns to a taut state.

[0053] The technical solution of the transmission mechanism of this embodiment is that at least one of the three rotating rollers is set as a position-adjustable rotating roller, so that the adjustable rotating roller can be moved and switched between the working position and a corresponding first position; and when the adjustable rotating roller is in its working position, the sum of the distances from the working positions of the other rotating rollers is greater than the sum of the distances from the first position of the adjustable rotating roller to the working positions of the other rotating rollers, that is, when the adjustable rotating roller is moved and switched from its working position to its first position, the perimeter of the triangle surrounded by the three rotating rollers will be reduced, so that the mop 300 is in a relaxed state. Therefore, when the transmission mechanism of this embodiment is equipped with the annular mop 300 connected end to end and used on the cleaning device, when the user needs to replace the mop 300, only one adjustable rotating roller needs to be moved and switched from the working position to its first position, so that the mop 300 can be relaxed, so that the mop 300 can be easily pulled out from the end of the transmission mechanism.

[0054] And the new mop 300 can also be easily put on the transmission mechanism. After the mop 300 is replaced, the adjustable rotating roller is moved from its first position back to its working position, and the mop 300 can be tensioned together with the remaining rotating rollers again, so that the cleaning device can resume normal cleaning work.

[0055] Compared with the prior art method in which the rotating roller needs to be removed before disassembling the mop 300, the technical solution of this embodiment greatly reduces the complexity and difficulty of disassembling the mop 300 connected end to end, allowing users to replace the mop 300 connected end to end more simply and quickly, giving users a better product experience.

[0056] In some embodiments, when any one of the adjustable rotating rollers is in its first position, it is parallel to any one of the other rotating rollers, that is, when the adjustable rotating roller is moved and switched to its first position, the direction of its own axis remains unchanged. With such a design, it is possible to avoid the situation where the axis direction of the adjustable rotating roller is frequently changed during the movement and switching, thereby affecting the rotation stability of the rotating roller. Of course, in some other embodiments, when the adjustable rotating roller is in its first position, it may also be non-parallel to the other rotating rollers.

[0057] In some embodiments, the three rotating rollers include at least one first rotating roller 210 and at most two second rotating rollers 220. In the figure of the embodiment of the present application, one first rotating roller 210 and two second rotating rollers 220 are used as an example; of course, in some other embodiments, there may be two first rotating rollers 210 and one second rotating roller 220, or all three may be first rotating rollers 210. The first rotating roller 210 is an adjustable rotating roller, and the mounting bracket 100 includes a fixed bracket 110 and a movable bracket 120 corresponding to the first rotating roller 210 (since there is one first rotating roller 210 in the figure, there is also one movable bracket 120 corresponding to the first rotating roller 210; when there are multiple first rotating rollers 210, the movable bracket 120 is also a corresponding number), the first rotating roller 210 is rotatably mounted on the movable bracket 120, and the second rotating roller 220 is rotatably mounted on the fixed bracket 110. Each movable bracket 120 is movably connected to the fixed bracket 110 to drive the first rotating roller 210 corresponding to each other to move and switch between its working position and its first position; that is, in this embodiment, each first rotating roller 210 is indirectly connected to the fixed bracket 110 through the corresponding movable bracket 120. When any movable bracket 120 moves on the fixed bracket 110, the corresponding first rotating roller 210 follows the movable bracket 120 to move relative to the fixed bracket 110, thereby realizing the movement and switching of the first rotating roller 210 between its working position and its first position. The movable connection between the movable bracket 120 and the fixed bracket 110 can be a rotating connection, a sliding connection, etc.

[0058] In some embodiments, the fixed bracket 110 and the movable bracket 120 may be connected by a limiting structure X, and the limiting structure X keeps the first rotating roller 210 in its working position. By setting the limiting structure X to limit the first rotating roller 210, the first rotating roller 210 can be stably kept in its working position, so that the first rotating roller 210 will not be triggered to move in error during the operation of the transmission mechanism, thereby ensuring the stability of the operation of the transmission mechanism. In some embodiments, a positioning structure may be further provided between the fixed bracket 110 and the movable bracket 120, so that when the first rotating roller 210 moves to its first position, the movable bracket 120 and the fixed bracket 110 are positioned and fixed by the positioning structure, so that the first rotating roller 210 is kept in the first position, so that the user can disassemble and assemble the mop 300 conveniently.

[0059] Combination Figure 1 and Figure 2 And refer to Figure 5 and Figure 6 , introduces a first solution of the movable connection between the movable bracket 120 and the fixed bracket 110. In this embodiment, at least one movable bracket 120 is connected to the fixed bracket 110 by rotation, and the rotation axis of the movable bracket 120 is parallel to the axis of the first rotating roller 210; at least one movable bracket 120 rotates relative to the fixed bracket 110 (i.e., rotates around its rotation axis) to drive the corresponding first rotating roller 210 to move and switch between its working position and the first position. In this embodiment, the rotation axis of the movable bracket 120 is designed to be parallel to the axis of the first rotating roller 210, so that when the movable bracket 120 drives the first rotating roller 210 to move between its working position and the first position by rotation, the axis direction of the first rotating roller 210 remains unchanged, so that the position movement and switching of the first rotating roller 210 has no effect on the rotation of the first rotating roller 210 itself, and even if the transmission mechanism is used for a long time (many times of disassembly, assembly and replacement of the mop 300), the first rotating roller 210 can still maintain stable operation.

[0060] Reference Figure 2 , Figure 5In some embodiments, when all the first rotating rollers 210 are in their working positions, the rotation axis of at least one movable bracket 120 is located between the corresponding first rotating roller 210 and an adjacent rotating roller (in the figure, since only one first rotating roller 210 is included, the adjacent rotating roller of the corresponding first rotating roller 210 is the second rotating roller 220; if two first rotating rollers 210 are included, the adjacent rotating roller of the corresponding first rotating roller 210 can be the first rotating roller 210 or the second rotating roller 220; if three first rotating rollers 210 are included, the adjacent rotating roller of the corresponding first rotating roller 210 is the first rotating roller 210), and the rotation axis of the movable bracket 120 is located in the same plane as the axis of the corresponding first rotating roller 210 and the axis of the adjacent rotating roller (the second rotating roller 220 in the figure). That is, as shown in the figure of this embodiment, by arranging the rotation axis of the movable bracket 120 between the first rotating roller 210 and an adjacent rotating roller (the second rotating roller 220 in the figure), and making the rotation axis of the movable bracket 120 coplanar with the axis of the first rotating roller 210 and the axis of the second rotating roller 220, the working position of the first rotating roller 210 is the farthest position from the second rotating roller 220 in all the positions where the first rotating roller 210 rotates following the movable bracket 120. In this way, when the movable bracket 120 rotates with the first rotating roller 210 toward the side close to another adjacent rotating roller (the other second rotating roller 220 in the figure), the perimeter of the triangle formed by the first rotating roller 210 and the remaining rotating rollers (the two second rotating rollers 220 in the figure) becomes smaller and smaller (that is, the mop 300 becomes looser and looser), so as to avoid the possibility that the mop 300 hinders the rotation of the first rotating roller 210 when the first rotating roller 210 rotates following the movable bracket 120, so that it is easier for the first rotating roller 210 to move from the working position to the first position.

[0061] In this embodiment, the first position of the first rotating roller 210 can be the position of the first rotating roller 210 after the movable bracket 120 rotates the first rotating roller 210 to a preset angle (such as 15°, 20°, 30°) toward a side close to another adjacent rotating roller (the second rotating roller 220).

[0062] Combination Figure 1 , Figure 2 , and refer to Figures 5 to 7In some embodiments, at least one movable bracket 120 includes two connecting arms 122 and a base 121 rotatably disposed on the fixed bracket 110, the rotation axis of the base 121 is the rotation axis of the movable bracket 120, the two connecting arms 122 are respectively fixed to the two ends of the base 121, and the two ends of the first rotating roller 210 corresponding to the two connecting arms 122 are respectively rotatably inserted into the two connecting arms 122. In this embodiment, all movable brackets 120 and the corresponding first rotating rollers 210 may be connected in the above manner, or only one or two movable brackets 120 and the corresponding first rotating rollers 210 may be connected in the above manner. In this embodiment, the two connecting arms 122 of the movable bracket 120 are fixed to the base 121, so that the two connecting arms 122 rotate synchronously with the base 121, and then the two ends of the first rotating roller 210 inserted on the two connecting arms 122 will move synchronously with the movable bracket 120, so that when the first rotating roller 210 moves and switches its position, the axial direction of the first rotating roller 210 will remain unchanged, so that the rotation of the first rotating roller 210 is not affected when the first rotating roller 210 moves and switches its position, thereby ensuring the stability of the normal operation of the first rotating roller 210.

[0063] Combination Figure 1 , Figure 2 , and refer to Figure 5 and Figure 6 In some embodiments, the fixed bracket 110 includes a bracket body 111 and two end seats 112, the two end seats 112 are respectively connected to the two ends of the bracket body 111, the two ends of the second rotating roller 220 are respectively rotatably plugged into the two end seats 112, the two ends of the base 121 are respectively rotatably plugged into the two end seats 112, and the bracket body 111 and the base 121 are located in the area surrounded by the three rotating rollers, so that the bracket body 111 and the base 121 will not hinder the disassembly and assembly of the mop 300. Among them, the area of ​​at least one of the two end seats 112 is smaller than the cross-sectional area of ​​the mop 300 tensioned by the three rotating rollers, ensuring that the mop 300 can be disassembled and assembled from at least one end of the transmission mechanism.

[0064] In some embodiments, the areas of the two end seats 112 are smaller than the cross-sectional area of ​​the mop 300 that is tensioned by the three rotating rollers, and the mop 300 can be disassembled and assembled from any end of the transmission mechanism.

[0065] In some embodiments, both ends of the movable bracket 120 are respectively connected to the corresponding end seat 112 through a limiting structure X, and the limiting structure X includes a limiting buckle 11 and a limiting hole 12, one of the limiting buckle 11 and the limiting hole 12 is arranged on the connecting arm 122, and the other one is arranged on the end seat 112.

[0066] Combination Figure 1 , Figure 2, and refer to Figure 5 and Figure 6 Taking the limiting buckle 11 being provided on the connecting arm 122 and the limiting hole 12 being provided on the end seat 112 as an example, the limiting buckle 11 is buckled in the limiting hole 12. In this embodiment, the two ends of the movable bracket 120 are respectively buckled with the limiting holes 12 on the corresponding end seat 112 through the limiting buckles 11, so that the movable bracket 120 and the end seat 112 are kept fixed, and then the first rotating roller 210 rotatably installed on the movable bracket 120 is fixed in its working position, so that the transmission mechanism stably maintains the tension on the mop 300, ensuring that the mop 300 can stably perform cleaning work. When the mop 300 needs to be disassembled or assembled, the locking state of the limit buckle 11 and the limit hole 12 is first released, and then the movable bracket 120 is rotated relative to the fixed bracket 110 to drive the first rotating roller 210 to move and switch to the first position, and the mop 300 is disassembled or replaced. After the mop 300 is replaced, the movable bracket 120 is rotated relative to the fixed bracket 110 to drive the first rotating roller 210 to move and switch back to the working position, and the limit buckle 11 and the limit hole 12 are restored to the locking state.

[0067] Reference Figures 8 to 10 , introduces a second solution in which the movable bracket 120 is movably connected to the fixed bracket 110. In this embodiment, at least one movable bracket 120 and the fixed bracket 110 slide in a direction perpendicular to the axis of the first rotating roller 210, and the movable bracket 120 slides back and forth along the first direction relative to the fixed bracket 110 to drive the corresponding first rotating roller 210 to move and switch between its working position and the first position. In the figure of this embodiment, since only one first rotating roller 210 and one movable bracket 120 are included, the direction perpendicular to the axis of the first rotating roller 210 is referred to as the first direction, that is, Figure 8 and Fig.10 The direction indicated by the arrow in (indicated by A); it should be noted that, in other embodiments, when there are multiple first rotating rollers 210 and multiple corresponding movable brackets 120, if the multiple movable brackets 120 are all slidably matched with the fixed bracket 110, the sliding directions of the various movable brackets 110 relative to the fixed bracket 110 are not the same direction, that is, each movable bracket 110 has its own sliding direction. In this embodiment, when the movable bracket 120 drives the first rotating roller 210 to slide toward the inside of the mop 300 along the first direction, the distances from the first rotating roller 210 to the other two rotating rollers are reduced. Therefore, in this embodiment, the first position of the first rotating roller 210 can be the position of the first rotating roller 210 after the movable bracket 120 drives the first rotating roller 210 to slide along the first direction toward the inside of the mop 300 for any distance (for example, 1 cm, 1.5 cm, 2 cm).

[0068] Further references Figures 12 to 15In this embodiment, at least one movable bracket 120 includes a base 121 and two connecting arms 122 respectively arranged at both ends of the base 121, and the two ends of the first rotating roller 210 are rotatably inserted into the two connecting arms 122; the fixed bracket 110 includes a bracket body 111 and two end seats 112 respectively connected to the two ends of the bracket body 111, and the two ends of the second rotating roller 220 are rotatably inserted into the two end seats 112, and the base 121 is located between the two end seats 112. The bracket body 111 and the base 121 are located in the area surrounded by the three rotating rollers, so that the bracket body 111 and the base 121 will not hinder the disassembly and assembly of the mop 300. In this embodiment, the base 121 and the bracket body 111 can be slidably matched in the direction perpendicular to the axis of the first rotating roller 210 (i.e., the first direction) to realize the sliding connection between the movable bracket 120 and the fixed bracket 110; or the two connecting arms 122 can be slidably matched with the two end seats 112 in the direction perpendicular to the axis of the first rotating roller 210 (i.e., the first direction) to realize the sliding connection between the movable bracket 120 and the fixed bracket 110; or the base 121 and the bracket body 111 can be slidably matched in the first direction, and combined with the two connecting arms 122 and the two end seats 112 in the first direction to realize the sliding connection between the movable bracket 120 and the fixed bracket 110.

[0069] Reference Figures 12 to 15 In this embodiment, the two connecting arms 122 are fixed to the base 121, so that the two connecting arms 122 slide synchronously with the base 121, thereby ensuring that the two ends of the first rotating roller 210 move synchronously along the first direction with the base 121. In this way, when the first rotating roller 210 moves and switches its position, the axial direction of the first rotating roller 210 will remain unchanged, so that the rotation of the first rotating roller 210 is not affected when the first rotating roller 210 moves and switches its position, thereby ensuring the stability of the normal operation of the first rotating roller 210.

[0070] In some embodiments, the limiting structure X may include an elastic component, which applies an elastic force to the movable bracket 120 and the fixed bracket 110 to prevent the base 121 and the bracket body from sliding toward each other, so that the corresponding first rotating roller 210 is maintained in the working position of the tensioning mop 300. That is, the elastic component applies a force to the movable bracket 120 to prevent it from driving the corresponding first rotating roller 210 to move to the first position, so that the first rotating roller 210 is maintained in its working position to tension the mop 300. By applying a force to the movable bracket 120 by the elastic component, the first rotating roller 210 can be prevented from accidentally moving to its first position during the normal cleaning operation of the transmission mechanism, thereby ensuring the stable operation of the transmission mechanism. Among them, the elastic component can be a spring, an elastic rubber block, an elastic rope, etc. Of course, the limiting mechanism can also include a clamping structure arranged between the movable bracket 120 and the fixed bracket 110, and the movable bracket 120 is fixed to the fixed bracket 110 by the clamping structure, so that the first rotating roller 210 can be more stably maintained in its working position.

[0071] Reference Figures 12 to 15 In some embodiments, the support body 111 is provided with a first slide groove 21 that is directly opposite to the base 121 of the movable support 120, and the base 121 of the movable support 120 is provided with a first slider 22 inserted in the first slide groove 21. The first slider 22 can be inserted into the first slide groove 21 to achieve sliding cooperation between the movable support 120 and the fixed support 110. In some embodiments, the end seat 112 is provided with a second slide groove 203, and two connecting arms 122 are respectively slidably provided in the second slide grooves 203 of the two end seats 112. The two connecting arms 122 are respectively connected to the sliding second slide grooves 203 on the two end seats 112 to achieve sliding cooperation between the movable support 120 and the fixed support 110.

[0072] Reference Figures 10 to 12In this embodiment, the fixed bracket 110 and the movable bracket 120 are also connected by a reset elastic member T. The reset elastic member T applies an elastic force to the movable bracket 120 and the fixed bracket 110 to prevent the base 121 and the bracket body from sliding toward each other, that is, the reset elastic member T applies an action force to the movable bracket 120 to prevent it from driving the first rotating roller 210 to move to the first position, so that the corresponding first rotating roller 210 keeps the mop 300 tensioned, that is, the corresponding first rotating roller 210 keeps it in the working position. When the mop 300 needs to be disassembled or assembled, the first rotating roller 210 is pressed inward to move the first rotating roller 210 to its first position and locked, and the mop 300 is disassembled or replaced. After the replacement of the mop 300 is completed, when the lock of the first rotating roller 210 is released, the first rotating roller 210 can automatically return to the working position under the action of the elastic reset member T, without the need for additional operations by the user, and it is more convenient to use. At the same time, the resetting elastic member applies a force to the movable bracket 120, which can increase the tension of the first rotating roller 210 on the mop 300, and better prevent the first rotating roller 210 from accidentally moving to its first position during the normal cleaning process of the transmission mechanism, thereby ensuring that the cleaning device can perform the cleaning work stably. The elastic resetting member T of this embodiment can be a spring, an elastic rubber block, etc.

[0073] In some embodiments, a locking matching structure is further provided between the fixed bracket 110 and the movable bracket 120. When the movable bracket 120 moves and switches to the first position with the corresponding first rotating roller 210, the movable bracket 120 and the fixed bracket 110 are locked by the locking matching structure; an unlocking component is provided at the end of the end seat 112 or the movable bracket 120, which is used to drive the locking matching structure to unlock. In this embodiment, by providing a locking matching structure on the fixed bracket 110 and the movable bracket 120, when the user needs to disassemble and assemble the mop 300, by squeezing the first rotating roller 210 inward to move the first rotating roller 210 to its first position, the locking matching structure locks the movable bracket 120 with the fixed bracket 110, so that the first rotating roller 210 installed on the movable bracket 120 is locked in its first position, which can better facilitate the user to disassemble and replace the mop 300. After the user replaces the mop 300, the user can drive the locking matching structure through the unlocking component to unlock the movable bracket 120, so that the movable bracket 120 can drive the first rotating roller 210 to automatically return to the working position to tension the mop 300 under the action of the elastic component or the elastic return member T, thereby further simplifying the overall disassembly, assembly and replacement operation of the mop 300.

[0074] Reference Figures 12 to 15In some embodiments, the locking matching structure includes two card slots 201 and two elastic buckles 202. The two card slots 201 are respectively provided at two ends of the fixed bracket 110, and the two elastic buckles 202 are respectively provided at two ends of the corresponding movable bracket 120. When the movable bracket 120 moves to the first position with the corresponding first rotating roller 210, the two elastic buckles 202 are respectively locked in the two card slots 201, locking the movable bracket 120 and the fixed bracket 110, so that the first rotating roller 210 is maintained in its first position. In this embodiment, Fig.12 In the embodiment, two slots 201 are respectively disposed at two ends of the first slide slot 21, and two elastic buckles 202 are respectively disposed at two ends of the first slider 22. In addition, the slots 201 and the elastic buckles 202 can also be disposed at other positions of the movable bracket 120 and the fixed bracket 110, respectively.

[0075] Reference Figures 12 to 15 In this embodiment, the unlocking assembly includes two buttons 31. The two buttons 31 are respectively provided with two end seats 112 on the side facing away from the bracket body 111 and corresponding to the position of the card slot 201. One end of the button 31 (referred to as the active end) is penetrated by the end seat 112 and penetrates the bottom surface of the corresponding card slot 201, that is, the active end of the button 31 extends into the card slot 201, and the active end of the button 31 is used to squeeze the elastic buckle 202 out of the card slot 201. When it is necessary to release the lock, the user only needs to press the two buttons 31 on the two end seats 112 at the same time, so that the active ends of the two buttons 31 squeeze the elastic buckles 202 at both ends of the movable bracket 120 respectively, and the elastic buckles 202 shrink back due to the squeezing of the active ends of the buttons 31, and then the elastic buckle 202 is separated from the card slot 201, that is, the lock between the movable bracket 120 and the fixed bracket 110 is released, and the unlocking operation is very simple.

[0077] In some embodiments, the number of the first rotating roller 210 may be one, and the number of the second rotating rollers 220 may be two, that is, there is only one adjustable rotating roller and two non-adjustable rotating rollers, so that the structure of the transmission mechanism is simpler.
