[0042] In view of the problem of insufficient cleaning power of the rotary brush on the existing cleaning machine, the first embodiment of the present utility model provides a cleaning mechanism. Please refer to Figures 1 to 8 , the cleaning mechanism includes a driving assembly 10 and a cleaning assembly 20. The cleaning assembly 20 includes a support frame 21 and a flexible cleaning member 22. The support frame 21 is connected to the driving assembly 10, and the support frame 21 has a first position parallel to the surface to be cleaned 30 and a second position inclined to the surface to be cleaned 30. When the support frame 21 is in the first position, please refer to Figures 1 to 3 the structure shown. When the support frame 21 is in the second position, please refer to Figures 4 to 6 the structure shown. The flexible cleaning member 22 is laid on the side of the support frame 21 away from the driving assembly 10, so that the flexible cleaning member 22 can clean the surface to be cleaned 30. The driving assembly 10 is used to drive the support frame 21 to drive the flexible cleaning member 22 to rotate, so that the flexible cleaning member 22 can achieve efficient cleaning of the surface to be cleaned 30 during rotation. Moreover, the driving assembly 10 can drive the support frame 21 to switch from one of the first position and the second position to the other of the first position and the second position. That is to say, when there are no stubborn stains on the surface to be cleaned 30, this embodiment can drive the support frame 21 to drive the flexible cleaning member 22 to achieve efficient cleaning of the surface to be cleaned 30 in the first position through the driving assembly 10. When there are stubborn stains on the surface to be cleaned 30, this embodiment can drive the support frame 21 to drive the flexible cleaning member 22 in the second position to remove the stubborn stains on the surface to be cleaned 30. This is because when the support frame 21 is in the second position, the entire cleaning assembly 20 in the rotary cleaning operation will be inclined to the surface to be cleaned 30. Therefore, the ground area of the cleaning assembly 20 can be reduced, and the support frame 21 can apply a greater cleaning force to the surface to be cleaned 30 through the flexible cleaning member, so that the cleaning assembly 20 can achieve the cleaning operation of stubborn stains under a greater cleaning force.

[0043] It can be seen that the cleaning mechanism provided in this embodiment includes a driving component 10 and a cleaning component 20. The support frame 21 of the cleaning component 20 is connected to the driving component 10. The support frame 21 has a first position parallel to the surface to be cleaned 30 and a second position inclined to the surface to be cleaned 30. The flexible cleaning member 22 is laid on the side of the support frame 21 away from the driving component 10. The driving component 10 is used to drive the support frame 21 to drive the flexible cleaning member 22 to rotate, and can drive the support frame 21 to switch back and forth between the first position and the second position. Usually, the support frame 21 can drive the flexible cleaning member 22 to clean the surface to be cleaned 30 at the first position under the drive of the driving component 10, so as to efficiently remove the stains on the surface to be cleaned 30 through the flexible cleaning member 22. When there are relatively stubborn stains on the surface to be cleaned 30, in order to improve the cleaning strength of the cleaning component 20 on the surface to be cleaned 30, the present application can drive the support frame 21 to the second position through the driving component 10 and make the support frame 21 drive the flexible cleaning member 22 to rotate to clean the surface to be cleaned 30. Since the support frame 21 is inclined to the surface to be cleaned 30 (such as the ground, tabletop, wall, etc.), the ground area of the cleaning component 20 can be reduced. During the process of the support frame 21 driving the flexible cleaning member 22 to rotate and clean, the support frame 21 can apply a greater cleaning force to the surface to be cleaned 30 through the flexible cleaning member 22, thereby improving the cleaning strength of the cleaning component 20 and the cleaning effect on the surface to be cleaned 30, and realizing the smooth removal of stubborn stains. At the same time, since the cleaning component 20 can switch between the first position and the second position under the drive of the driving component 10 to clean the surface to be cleaned 30, the flexibility of use of the cleaning component 20 is improved, and the user can make the cleaning component 20 achieve efficient cleaning of the surface to be cleaned 30 at the first position or the second position according to different cleaning environments.

[0044] The flexible cleaning member 22 in this embodiment can be a mop, a rubber brush, a sponge brush, etc. Regardless of the structure of the flexible cleaning member 22, when the support frame 21 is in the second position, the support frame 21 can apply a greater cleaning force to the surface to be cleaned 30 through the flexible cleaning member 22 to remove stubborn stains, thereby improving the cleaning efficiency and cleaning effect of the cleaning device provided in this embodiment.

[0045] The driving component 10 in this embodiment includes a driving part 11 and a rotating part 12. The driving part 11 includes a connecting shaft 113. At least part of the connecting shaft 113 extends out of the driving part 11 and can rotate around its own axis in the first direction or the second direction under the drive of the driving part 11. The support frame 21 is connected to the end of the connecting shaft 113 away from the driving part 11, and the second direction is opposite to the first direction.

[0046] Please refer to Figure 3 and Figure 6, in this embodiment, the driving component 11 may specifically include a motor 111 and a gearbox 112. The output shaft of the motor 111 is rotatably connected to the gearbox 112. The connecting shaft 113 is installed inside the gearbox 112 and extends outside the gearbox 112 to be connected to the support frame 21. The gearbox 112 can transmit the kinetic energy output by the motor 111 to the support frame 21 through the connecting shaft 113, so that the support frame 21 can drive the flexible cleaning member 22 to rotate in the first direction or the second direction. For example, when the motor 111 rotates forward, the connecting shaft 113 drives the support frame 21 to rotate in the first direction; when the motor 111 rotates in reverse, the connecting shaft 113 drives the support frame 21 to rotate in the second direction, so that the support frame 21 can drive the flexible cleaning member 22 to clean the surface to be cleaned 30 during rotation.

[0047] The rotating component 12 in this embodiment includes a connecting portion 121 and a mounting portion 122. The connecting portion 121 is connected to the driving component 11. The mounting portion 122 is disposed between the support frame 21 and the connecting portion 121. The connecting portion 121 is placed on the mounting portion 122 and can rotate relative to the mounting portion 122. Wherein, there are limiting platforms with different heights between the connecting portion 121 and the mounting portion 122. When the driving component 11 drives the connecting shaft 113 to rotate, the connecting portion 121 rotates relative to the mounting portion 122 between the limiting platforms with different heights by overcoming the friction force between it and the mounting portion 122, so as to switch the support frame 21 between the first position and the second position.

[0048] Specifically, if the initial position of the support frame 21 is the first position, and at this time the connecting shaft 113 drives the support frame 21 to rotate in the first direction. When it is necessary to remove stubborn stains on the surface to be cleaned 30, this embodiment can control the driving component 11 to drive the support frame 21 to rotate in the second direction. At this time, the driving component 11 will generate a torque in the second direction, and this torque will be greater than the friction force between the connecting portion 121 and the mounting portion 122, so that the connecting portion 121 can rotate relative to the mounting portion 122 between the limiting platforms with different heights by overcoming the friction force between it and the mounting portion 122. When one side of the connecting portion 121 rotates to be located on the higher limiting platform and the other side is located on the lower limiting platform, the driving component 11 and the support frame 21 as a whole can be in an inclined state, so that the support frame 21 is in the second position inclined to the surface to be cleaned 30.

[0049] When there are no stubborn stains to be removed on the surface 30 to be cleaned, in this embodiment, after the driving member 11 drives the support frame 21 to stop rotating in the second direction, the support frame 21 is driven to rotate in the first direction. At this time, the driving member 11 will generate a torsion force in the first direction. When this torsion force is greater than the frictional force between the connecting portion 121 and the mounting portion 122, the connecting portion 121 will overcome the frictional force with the mounting portion 122 and rotate the connecting portion 121 relative to the mounting portion 122 to the limiting platform at the same height. Since the driving member 11 and the connecting portion 121 are connected together and can rotate relative to the mounting portion 122, when the connecting portion 121 is on the limiting platform at the same height, the driving member 11 and the support frame 21 as a whole are in a state parallel to the surface 30 to be cleaned, that is, the support frame 21 is in the first position parallel to the surface 30 to be cleaned, enabling the support frame 21 to drive the flexible cleaning member 22 to clean the surface 30 to be cleaned at a position parallel to the surface 30 to be cleaned.

[0050] As can be seen from the above, in this embodiment, the torsion force generated when the driving member 11 switches the rotation direction of the support frame 21 is used to drive the connecting portion 121 to rotate relative to the mounting portion 122 by overcoming the frictional force between the connecting portion 121 and the mounting portion 122, so that the support frame 21 switches between the first position and the second position. The control is simple and convenient, without the need to add an additional power driving source, saving the energy consumption of the cleaning mechanism.

[0051] In this embodiment, as Figure 7 shown, the limiting platform includes a first limiting platform 221 and a second limiting platform 222. The first limiting platform 221 and the second limiting platform 222 are arranged on the side of the mounting portion 122 close to the connecting portion 121. At least part of the first limiting platform 221 is adjacent to one side of the second limiting platform 222 in the first direction or the second direction, so that the connecting portion 121 can rotate from the first limiting platform 221 to the second limiting platform 222, or from the second limiting platform 222 to the first limiting platform 221. And, the first limiting platform 221 is closer to the driving member 11 than the second limiting platform 222, that is, the height of the first limiting platform 221 is higher than that of the second limiting platform 222.

[0052] Wherein, one side of the connecting portion 121 along the radial direction of the connecting shaft 113 is located on one of the first limiting platform 221 and the second limiting platform 222, and the other side of the connecting portion 121 along the radial direction of the connecting shaft 113 can reciprocate between the first limiting platform 221 and the second limiting platform 222. That is to say, at least one side of the connecting portion 121 in this embodiment is always located on the first limiting platform 221 or the second limiting platform 222. By enabling the other side of the connecting portion 121 to reciprocate between the first limiting platform 221 and the second limiting platform 222, the connecting portion 121 can drive the support frame 21 to the first position or the second position. For example, when each part of the connecting portion 121 is located on the first limiting platform 221 or the second limiting platform 222, the connecting portion 121 is parallel to the surface to be cleaned 30, and further enables the driving component 11 connected to the connecting portion 121 to drive the support frame 21 to be located at the first position parallel to the surface to be cleaned 30. When one side of the connecting portion 121 is located on the first limiting platform 221 and the other side is located on the second limiting platform 222, the connecting portion 121 is inclined to the surface to be cleaned 30, and further enables the driving component 11 connected to the connecting portion 121 to drive the support frame 21 to be located at the first position inclined to the surface to be cleaned 30.

[0053] Specifically, in this embodiment, one side of the connecting portion 121 can be located on the second limiting platform 222, and the other side can reciprocate between the first limiting platform 221 and the second limiting platform 222. In the initial state, if the whole connecting portion 121 is located on the second limiting platform 222, that is, when the connecting portion 121 drives the support frame 21 to be parallel to the surface to be cleaned 30, the motor 111 drives the support frame 21 to drive the flexible cleaning member 22 to rotate and clean along the first direction. When it is necessary to switch the support frame 21 to the second position inclined to the surface to be cleaned 30 to drive the flexible member to rotate and clean, after controlling the motor 111 to drive the support frame 21 to stop rotating along the first direction, the motor 111 drives the support frame 21 to rotate reversely along the second direction. At this time, the torque generated by the motor 111 is greater than the frictional force between the connecting portion 121 and the mounting portion 122. When the whole connecting portion 121 rotates relative to the mounting portion 122, one side of the connecting portion 121 will move from the second limiting platform 222 to the first limiting platform 221. Due to the height difference between the first limiting platform 221 and the second limiting platform 222, the horizontal plane where one side of the connecting portion 121 located on the second limiting platform 222 is lower than the horizontal plane where the side of the connecting portion 121 located on the first limiting platform 221 is, that is, the whole connecting portion 121 is in an inclined state. At this time, the driving component 11 connected to the connecting portion 121 will drive the support frame 21 to be in the second position inclined to the surface to be cleaned 30, increasing the cleaning force applied to the surface to be cleaned 30 when the support frame 21 drives the flexible cleaning member 22 to rotate in the second position, so as to achieve the removal of stubborn stains. The first limiting platform 221 and the second limiting platform 222 are convenient to process and have a simple structure. There is no need to add complex driving sources and lifting structures. Moreover, only by enabling one side of the connecting portion 121 to move between the first limiting platform 221 and the second limiting platform 222, the support frame 21 can be switched between the first position and the second position. The connecting portion 121 does not need to have a large rotation amplitude, and the control is simple, convenient, efficient and reliable.

[0054] To improve the accuracy of the switching of the support frame 21 between the first position and the second position, and to enable the support frame 21 to stably maintain its current position to clean the surface to be cleaned 30 without changing the rotation direction of the support frame 21. In this embodiment, a sliding limit structure 13 is provided between the connecting portion 121 and the mounting portion 122. The sliding limit structure 13 is used to guide the connecting portion 121 to rotate on the limit table, so as to prevent the connecting portion 121 from deviating from the predetermined route during the rotation process, improve the reliability and stability of the connecting portion 121 during the rotation process, and further ensure the accuracy and stability of the switching of the support frame 21 between different positions. Moreover, the sliding limit structure 13 can also hold the support frame 21 in the first position or the second position, so as to ensure that the support frame 21 can stably maintain its current position to drive the flexible cleaning member 22 to rotate and clean. For example, when the connecting portion 121 rotates to the support frame 21 being in the first position or the second position, the connecting portion 121 is restricted from rotating relative to the first limit table 221 and the second limit table 222 through the sliding limit structure 13, so as to hold the support frame 21 in the current position and ensure that the support frame 21 can stably maintain its current position to drive the flexible cleaning member 22 to rotate and clean.

[0055] Among them, there are at least two second limit tables 222. The sliding limit structure 13 in this embodiment includes a first chute 131 and a first slider 132. The first chute 131 is provided on the side of the mounting portion 122 close to the connecting portion 121, and the outer contour of the projection of the first chute 131 along the axial direction of the connecting shaft 113 is arc-shaped. The first limit table 221 is located at the bottom of the first chute 131. At least one second limit table 222 is located at the bottom of the first chute 131 and is adjacent to the first limit table 221. At least one second limit table 222 is located outside the first chute 131 and overlaps with the connecting portion 121. The first slider 132 is provided on the side of the connecting portion 121 close to the mounting portion 122. The first slider 132 is adapted to the first chute 131 and is located in the first chute 131. That is to say, in this embodiment, through the sliding fit between the first chute 131 and the first slider 132, it can be ensured that the connecting portion 121 will not deviate during the reciprocating movement between the first limit table 221 and the second limit table 222, and the accuracy and stability of the switching of the support frame 21 between different positions are improved.

[0056] The first slider 132 of the sliding limit structure 13 can reduce the friction between the connecting portion 121 and the mounting portion 122, so that the connecting portion 121 can rotate more smoothly relative to the mounting portion 122. When the connecting portion 121 is subjected to the torque generated by the driving member 11, the first slider 132 can slide between the first limiting platform 221 and the second limiting platform 222 along the sliding track defined by the first chute 131 under the drive of the connecting portion 121, improving the accuracy of the rotation position of the connecting portion 121 and preventing the connecting portion 121 from shifting. Since the connecting portion 121 is misaligned to one side of the first chute 131 and is lapped on the second limiting platform 222 outside the first chute 131, when the first slider 132 slides onto the first limiting platform 221 and is blocked by the groove wall of the first chute 131, the connecting portion 121 can be maintained in an inclined state, and further the support frame 21 is maintained in the second position.

[0057] When the support frame 21 rotates along the second direction when it is in the second position, when it is necessary to return the support frame 21 to the first position, after driving the support frame 21 to stop rotating along the second direction by the driving member 11, the support frame 21 is driven to rotate along the first direction. When the support frame 21 starts to rotate along the first direction, the connecting portion 121 overcomes the friction with the mounting portion 122 and drives the first slider 132 to slide from the first limiting platform 221 to the second limiting platform 222. When the first slider 132 slides to the groove wall on the side of the first chute 131 away from the first limiting platform 221, the first slider 132 is restricted on the second limiting platform 222 by the groove wall of the first chute 131. At this time, since the misaligned portion of the connecting portion 121 with respect to the first chute 131 and the portion opposite to the first chute 131 are both located on the second limiting platform 222, the connecting portion 121 is in a parallel state, and further the support frame 21 is maintained in the first position parallel to the surface to be cleaned 30. At the same time, since the outer contour of the projection of the first chute 131 along the axial direction of the connecting shaft 113 is arc-shaped, it adapts to the rotation track of the connecting portion 121, enables the connecting portion 121 to drive the first slider 132 to slide smoothly in the first chute 131, and accurately limits the rotation angle of the connecting portion 121 without interfering with the rotation of the connecting portion 121.

[0058] Secondly, to make the friction between the connecting portion 121 and the mounting portion 122 smaller, such as Figure 3 and Figure 6As shown, in this embodiment, the connecting portion 121 is placed on the groove wall of the first sliding groove 131, and a third installation gap is provided between the first sliding block 132 and the first sliding groove 131. Thus, in the process of guiding the sliding of the connecting portion 121 through the sliding fit between the first sliding block 132 and the first sliding groove 131, since the first sliding block 132 does not directly contact the groove wall of the first sliding groove 131, the contact area between the connecting portion 121 and the installation portion 122 is reduced, and further the frictional force between the connecting portion 121 and the installation portion 122 is reduced. When the connecting portion 121 rotates to the position where the support frame 21 is in the first position or the second position, the first sliding block 132 is blocked by the groove wall of the first sliding groove 131, and thus the support frame 21 can be held in the first position or the second position.

[0059] The sliding limit structure 13 in this embodiment further includes a second sliding groove 133 and a second sliding block 134. The second sliding groove 133 is provided on the side of the installation portion 122 close to the connecting portion 121. The outer contour of the projection of the second sliding groove 133 along the axial direction of the connecting shaft 113 is arc-shaped, and the second sliding groove 133 is offset from the first limiting platform 221. At least one second limiting platform 222 is located in the second sliding groove 133, and at least one second limiting platform 222 is located outside the second sliding groove 133 and is adjacent to the first limiting platform 221. The second sliding block 134 is provided on the side of the connecting portion 121 close to the installation portion 122, and the second sliding block 134 is adapted to the second sliding groove 133 and is located in the second sliding groove 133. That is to say, in this embodiment, through the sliding fit between the second sliding groove 133 and the second sliding block 134, it can be ensured that during the rotation of the connecting portion 121 relative to the second limiting platform 222, no offset will occur, thereby improving the accuracy and stability when the support frame 21 switches between different positions.

[0060] Similarly, the second sliding block 134 of the sliding limit structure 13 can also reduce the frictional force between the connecting portion 121 and the installation portion 122, so that the connecting portion 121 can rotate more smoothly relative to the installation portion 122. When the connecting portion 121 is acted on by the torque generated by the driving component 11, the second sliding block 134 can slide on the second limiting platform 222 along the sliding track defined by the second sliding groove 133 under the drive of the connecting portion 121, improving the accuracy of the rotation position of the connecting portion 121 and preventing the connecting portion 121 from generating an offset. Since the connecting portion 121 offset on one side of the second sliding groove 133 can reciprocate between the first limiting platform 221 and the second limiting platform 222 located outside the second sliding groove 133, when the second sliding block 134 slides onto the first limiting platform 221, the second sliding block 134 will be blocked by the groove wall of the second sliding groove 133, so that the connecting portion 121 is held in an inclined state, and thus the support frame 21 is held in the second position.

[0061] When the support frame 21 rotates in the second direction when it is in the second position, when it is necessary to return the support frame 21 to the first position, after the driving member 11 drives the support frame 21 to stop rotating in the second direction, the support frame 21 is driven to rotate in the first direction. When the support frame 21 starts to rotate in the first direction, under the torque action of the driving member 11, the connecting portion 121 overcomes the friction force with the mounting portion 122 and drives the second slider 134 to slide in the second chute 133. When the portion of the connecting portion 121 misaligned with the second chute 133 slides from the first limiting platform 221 to the second limiting platform 222, the second slider 134 will be blocked by the groove wall of the second chute 133. At this time, the portion of the connecting portion 121 misaligned with the second chute 133 and the portion opposite to the second chute 133 are both located on the second limiting platform 222, and the connecting portion 121 is in a parallel state, thereby making the support frame 21 in the first position parallel to the surface 30 to be cleaned. At the same time, since the outer contour of the projection of the second chute 133 along the axial direction of the connecting shaft 113 is arc-shaped, it adapts to the rotation trajectory of the connecting portion 121, enables the connecting portion 121 to drive the second slider 134 to slide smoothly in the second chute 133, and accurately limits the rotation angle of the connecting portion 121 without interfering with the rotation of the connecting portion 121.

[0062] Secondly, in order to make the friction force between the connecting portion 121 and the mounting portion 122 smaller, as Figure 3 and Figure 6 shown, in this embodiment, the connecting portion 121 is placed on the groove wall of the second chute 133, and a third mounting gap is provided between the second slider 134 and the second chute 133. Thus, in the process of guiding the sliding of the connecting portion 121 through the sliding fit of the second slider 134 and the second chute 133, since the second slider 134 does not directly contact the groove wall of the second chute 133, the contact area between the connecting portion 121 and the mounting portion 122 is reduced, and further the friction force between the connecting portion 121 and the mounting portion 122 is reduced. When the connecting portion 121 rotates to the support frame 21 being in the first position or the second position, the second slider 134 is blocked by the groove wall of the second chute 133, and the support frame 21 can be held in the first position or the second position.

[0063] A limiting groove 223 is further provided on one side of the mounting portion 122 in this embodiment close to the connecting portion 121, and the connecting portion 121 and the limiting platforms (i.e., the first limiting platform 221 and the second limiting platform 222) are both located in the limiting groove 223. Thus, when the connecting portion 121 rotates or shakes greatly, the connecting portion 121 will not deflect a large angle relative to the mounting portion 122, and the stability and reliability of the overall structure of the cleaning mechanism can be improved during the process of switching the position of the support frame 21.

[0064] Axially along the connecting shaft 113, an avoidance hole 231 is penetrated through the bottom of the limit groove 223. The first limit platform 221 and the second limit platform 222 are arranged on the bottom of the limit groove 223 and are located between the avoidance hole 231 and the outer peripheral wall of the limit groove 223. The avoidance hole 231 can reduce the contact area between the connecting portion 121 and the mounting portion 122, thereby reducing the frictional force between the connecting portion 121 and the mounting portion 122, ensuring that the connecting portion 121 can rotate relative to the mounting portion 122 under the action of the torque generated when the driving component 11 changes the rotation direction, overcoming the frictional force with the mounting portion 122.

[0065] Specifically, as Figure 2 , Figure 5 , Figure 7 shown, when the sliding limit structure 13 includes a first sliding groove 131, a second sliding groove 133, a first slider 132 and a second slider 134, and the second limit platform 222 includes two, the first sliding groove 131 and the second sliding groove 133 are arranged at intervals on the bottom of the limit groove 223 and are located between the avoidance hole 231 and the outer peripheral wall of the limit groove 223. One of the second limit platforms 222 is located in the second sliding groove 133, and the first limit platform 221 and the other second limit platform 222 are both located in the first sliding groove 131. The first slider 132 and the second slider 134 are arranged on opposite sides of the connecting portion 121 along its own length direction and are respectively in sliding fit with the first sliding groove 131 and the second sliding groove 133. Thus, in this embodiment, by providing the avoidance hole 231 and the sliding limit structure 13, while reducing the frictional force between the connecting portion 121 and the mounting portion 122, it can also ensure that the connecting portion 121 can accurately and stably drive the support frame 21 to the first position or the second position through the sliding limit structure 13.

[0066] There is a first installation gap between the connecting portion 121 and the outer peripheral wall of the limiting groove 223 in this embodiment to prevent the outer peripheral wall of the limiting groove 223 from contacting the connecting portion 121, thereby further reducing the friction force between the connecting portion 121 and the installation portion 122 and ensuring that the outer peripheral wall of the limiting groove 223 does not interfere with the rotation of the connecting portion 121. The avoidance holes 231 in this embodiment can include one or multiple. When there is one avoidance hole 231, the processing of the installation portion 122 is more efficient and convenient. The shape of the avoidance hole 231 can include one of a circular hole, a rectangular hole, a diamond hole, etc. Among them, the maximum length of the connecting portion 121 is greater than the maximum width of the avoidance hole 231. For example, when the avoidance hole 231 is a circular hole, the maximum length of the connecting portion 121 is greater than the diameter of the avoidance hole 231, so as to ensure that the connecting portion 121 can be placed on the installation portion 122. The connecting portion 121 includes one of an oval plate, a rectangular plate, etc. For example, when the connecting portion 121 includes an oval plate, the major axis of the oval plate is greater than the diameter of the avoidance hole 231, so as to ensure that while reducing the friction force between the connecting portion 121 and the installation portion 122 through the avoidance hole 231, the connecting portion 121 can be stably placed on the installation portion 122.

[0067] Please refer to Figure 3 , a connecting hole 211 is provided on the connecting portion 121 of this embodiment. The connecting hole 211 communicates with the avoidance hole 231. The connecting shaft 113 passes through the connecting hole 211 and the avoidance hole 231 to be connected to the support frame 21, and there is a second installation gap between the connecting portion 121 and the support frame 21, so that while the connecting portion 121 can drive the support frame 21 to switch between the first position and the second position, the connecting portion 121 does not interfere with the rotation of the support frame 21. Specifically, a shaft hole 1121 is provided on one side of the gearbox 112 of the driving component 11 close to the connecting portion 121. The connecting shaft 113 passes out of the gearbox 112 from the shaft hole 1121 to be connected to the support frame 21. The connecting hole 211 of the connecting portion 121 is connected to the outer shell of the gearbox 112 at the shaft hole 1121, and a sealing ring 14 is provided between the connecting portion 121 and the outer shell of the gearbox 112 to prevent the sewage generated by the flexible cleaning member 22 on the support frame 21 from seeping into the gearbox 112 along the gap between the connecting portion 121 and the gearbox 112. A plurality of fixing holes 212 are also provided on the connecting portion 121, and the fixing holes 212 are arranged around the outer periphery of the connecting hole 211. As Figure 8 shown, fixing posts 1122 are provided on the gearbox 112 at positions corresponding to the fixing holes 212. The end of the fixing post 1122 away from the electrode penetrates into the fixing hole 212 to be fixedly connected to the connecting portion 121, thereby improving the connection stability between the connecting portion 121 and the driving component 11 and enabling the torque generated by the driving component 11 to be efficiently transmitted to the connecting portion 121, driving the connecting portion 121 to rotate relative to the installation portion 122 against the friction force between them.

[0068] To enable the connecting portion 121 to move more smoothly between the first limiting platform 221 and the second limiting platform 222, a sliding slope 224 is provided between the first limiting platform 221 and the second limiting platform 222, so that the connecting portion 121 can reciprocate between the first limiting platform 221 and the second limiting platform 222 along the sliding slope 224.

[0069] In addition, the support frame 21 in this embodiment specifically includes a support plate with a plate-like structure. The support plate provides a more balanced support force for each part of the flexible cleaning member 22 and enables the flexible cleaning member 22 to be laid on the support plate more tightly. The flexible cleaning member 22 is laid on the side of the support plate away from the driving component 11. When the support plate is in the second position, the flexible cleaning member 22 can be inclined with respect to the surface to be cleaned 30 under the support of the support plate. During the process of the support plate driving the flexible cleaning member 22 to rotate and clean, the support plate can apply a greater cleaning force to the surface to be cleaned 30 through the flexible cleaning member 22, thereby improving the cleaning effect on the surface to be cleaned 30 and efficiently and labor-savingly removing stubborn stains. The support frame 21 forms a first included angle with the surface to be cleaned 30 (the first included angle is Figure 1 the angle indicated by the symbol α in the figure). In this embodiment, the first included angle can be greater than 0° and less than 45°, so as to ensure that the support frame 21 can apply a greater cleaning force to the flexible cleaning member 22 in the inclined state. The first included angle can specifically include one of 3°, 4°, 5°, 8°, 13°, 15°, 20°, 24°, 26°, 28°, 30°, 32°, 35

[0070] °, 37°, 38°, 40°, 41°, 43°, 45°, etc. When installing this cleaning mechanism in a cleaning device, considering the spatial layout and cleaning effect of the cleaning device comprehensively, the preferred angle of the first included angle in this embodiment is 5°. That is to say, when the first included angle is 5°, it can not only ensure that the cleaning force of the cleaning assembly 20 is large and the cleaning effect is good, but also does not increase the volume of the cleaning device, reducing the processing difficulty and cost of the cleaning device.

[0071] The second embodiment of the present utility model provides a cleaning device, which includes a cleaning mechanism. For the specific structure of the cleaning mechanism, please refer to the content provided in the first embodiment of the present utility model, and this embodiment will not be elaborated here.

[0072] The third embodiment of the present utility model provides a base station, which includes a cleaning device. For the structure of the cleaning device, please refer to the content provided in the second embodiment of the present utility model, and this embodiment will not be elaborated here.

[0073] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.

Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0074] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without further statement, these terms have no special meaning, and thus should not be construed as limiting the scope of protection of the present application.

[0075] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
