Currently, to prevent the mop from contaminating carpets, the cleaning robot typically raises the mop to a certain height to avoid the carpet after detecting it. However, if the mop is wet, water from the mop can easily drip onto the carpet as the cleaning robot passes over it, causing secondary contamination and a poor user experience. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a mopping assembly and a cleaning robot, so as to shield the mopping member when the cleaning robot passes over the carpet, thereby preventing the mopping member from dripping water onto the carpet.

The mopping assembly also includes an isolation member movable relative to the mop and a transmission structure for driving the isolation member to move. The isolation member has an isolation position located on the lower side of the mop to separate the mop from the surface to be cleaned, and an avoidance position away from the lower side of the mop and the surface to be cleaned. The transmission structure is used to drive the isolation member to switch between the isolation position and the avoidance position.

[0006] In some embodiments, the isolation member is a flexible isolation member, which is supported on the transmission structure and switches between the isolation position and the avoidance position along with the transmission structure.

[0007] In some embodiments, the transmission structure includes two synchronous belts, which are respectively arranged at the two ends of the mop along the length direction. The flexible isolation member is supported between the two synchronous belts. The two synchronous belts rotate synchronously, driving the flexible isolation member to switch between the upper side and the lower side of the mop, so that the flexible isolation member switches between the isolation position and the avoidance position.

[0011] In some embodiments, the transmission structure includes a pulling member and a winding member, the pulling member drives the flexible isolation member to move on the lower side of the mop to support the flexible isolation member on the lower side of the mop so that the flexible isolation member is in the isolation position; the winding member winds up the flexible isolation member so that the flexible isolation member is in the avoidable position.

[0012] In some embodiments, the isolation member is an isolation plate, the transmission structure is a linear telescopic transmission member, and the isolation plate is connected to the end of the linear telescopic transmission member.

[0013] In some embodiments, the mopping assembly further includes a driving structure, which is disposed on the mopping bracket to drive the transmission structure to move the isolation member.

[0020] 2. By adopting a flexible isolator as the isolator, and the flexible isolator is driven by a synchronous belt to rotate and switch between the isolation position and the avoidance position, the flexibility of the flexible isolator can be utilized to drive the flexible isolator to rotate relative to the mop so that the avoidance position of the flexible isolator is located on the upper side of the mop, and the isolation position is located on the lower side of the mop.

[0057] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0059] An embodiment of the present application provides a mopping assembly, which includes a mopping bracket and a mop disposed on the mopping bracket. The mopping assembly also includes an isolation member movable relative to the mop and a transmission structure for driving the isolation member to move. The isolation member has an avoidance position located on the lower side of the mop to separate the mop from the surface to be cleaned, and an avoidance position away from the lower side of the mop and the surface to be cleaned. The transmission structure is used to drive the isolation member to switch between the isolation position and the avoidance position.

[0060] It can be understood that by arranging an isolation member and a transmission structure on the mopping assembly, the isolation member has an isolation position located on the lower side of the mop to separate the mop from the surface to be cleaned, and an avoidance position away from the lower side of the mop and the surface to be cleaned. In this way, when the isolation member is in the avoidance position, the mop can clean the surface to be cleaned, and when the isolation member is in the isolation position, the isolation member can separate the mop and the surface to be cleaned. In this way, when passing through the carpet, the isolation member can be located in the isolation position, and the isolation member blocks the mop from the lower side of the mop to prevent water droplets on the mop from falling on the carpet, thereby improving the user experience.

[0061] In some embodiments, reference Figures 1 to 7 The isolation member 2 is a flexible isolation member, which is supported on the transmission structure 3 and switches between the isolation position and the avoidance position along with the transmission structure 3.

[0062] The flexible isolating member may be a plastic film, such as a PET film, or a rubber film, which is not specifically limited here.

[0063] Reference Figures 1 to 4 The transmission structure 3 includes two synchronous belts 31, which are respectively provided at both ends of the mop in the length direction. The flexible isolator is supported between the two synchronous belts 31. The synchronous rotation of the two synchronous belts 31 can drive the flexible isolator to switch between the upper side and the lower side of the mop, so that the flexible isolator can switch between the isolation position and the avoidance position. The state of the flexible isolator in the isolation position is as follows: Figure 3 As shown, the state of the flexible isolation member when it is in the avoidance position is as follows Figure 4 shown.

[0064] It can be understood that the flexible isolator is supported between the two synchronous belts 31, and the rotation of the synchronous belt 31 drives the flexible isolator to move, thereby achieving the switching of the flexible isolator between the isolation position and the avoidance position. At this time, the synchronous belt 31 can rotate in one direction to switch the flexible isolator between the isolation position and the avoidance position. Alternatively, it can also rotate forward to move the flexible isolator from the avoidance position to the isolation position, and reverse to move the flexible isolator from the isolation position to the avoidance position. Among them, forward rotation and reverse rotation are clockwise rotation and counterclockwise rotation respectively, which are not specifically limited here.

[0065] By adopting a flexible isolation member 2, and the flexible isolation member being driven by the synchronous belt 31 to rotate and switch between the isolation position and the avoidance position, the flexibility of the flexible isolation member can be utilized to rotate relative to the mop so that the avoidance position of the flexible isolation member is located on the upper side of the mop, and the isolation position is located on the lower side of the mop. The structure is compact and easy to implement, which can reduce costs.

[0066] Furthermore, the transmission structure 3 also includes synchronous pulleys 32. At least two synchronous pulleys 32 are provided on the mopping bracket 1 corresponding to each synchronous belt 31. The synchronous belt 31 is wound around the at least two synchronous pulleys 32. It can be understood that the synchronous belt 31 is driven to rotate by the at least two synchronous pulleys 32 to drive the flexible isolation member to switch between the isolation position and the avoidance position.

[0067] It should be noted that the at least two synchronous wheels 32 supporting each synchronous belt 31 are sequentially arranged in a first direction, wherein the first direction is perpendicular to the length direction of the mop.

[0068] Optionally, the transmission structure 3 further includes a support shaft 33 for supporting the flexible isolating member, the support shaft 33 being disposed on the mopping bracket 1 and extending along the length direction of the mop cloth.

[0069] It can be understood that by setting the support shaft 33, the flexible isolation member can be supported so that the flexible isolation member can remain in a tensioned state when switching between the avoidance position and the isolation position, thereby preventing the flexible isolation member from interfering with other structures of the mopping assembly 100 during movement and causing damage or destruction.

[0070] It should be noted that the support shaft 33 may be located between the synchronous wheels 32 that respectively drive the two synchronous belts 31 , and the support shaft 33 may rotate synchronously with the synchronous wheels 32 , or the support shaft 33 may rotate freely to provide support for the flexible isolation member.

[0071] When there is one support shaft 33, the forward rotation of the synchronous belt 31 causes the flexible isolator to move from the avoidance position to the isolation position, while the reverse rotation causes the flexible isolator to move from the isolation position to the avoidance position. The flexible isolator is placed on the support shaft 33 during the movement. The forward rotation and the reverse rotation are clockwise and counterclockwise respectively, which are not specifically limited here. When there are two support shafts 33, the two support shafts 33 are spaced apart in a direction perpendicular to the length of the mop. At this time, the synchronous belt 31 can rotate in one direction to switch the flexible isolator between the isolation position and the avoidance position. The flexible isolator is placed on one of the support shafts 33 when moving from the isolation position to the avoidance position, and is placed on the other support shaft 33 when moving from the avoidance position to the isolation position.

[0072] Optionally, the mopping assembly 100 further includes auxiliary wheels 14 that can rotate around their own axes. Auxiliary wheels 14 are provided at both ends of the mopping bracket 1 in the length direction of the mop. The mop is located between the auxiliary wheels 14 at both ends of the mopping bracket 1, and the auxiliary wheels are used to contact the ground.

[0073] It can be understood that the mopping assembly 100 supports the mopping assembly 100 by contacting the surface to be cleaned with the auxiliary wheels 14, so that when the mop is mopping the surface to be cleaned, the auxiliary wheels 14 can keep a certain distance between the remaining structure of the mopping assembly 100 and the surface to be cleaned, thereby avoiding friction damage caused by contact between the remaining structure of the mopping assembly 100 and the surface to be cleaned.

[0074] The above-mentioned mop includes a base and fluff arranged on the base and capable of mopping the surface to be cleaned. When the flexible isolator is in the avoidance position, the fluff contacts the surface to be cleaned and can be mopped. When the flexible isolator is in the isolation position, the flexible isolator is pressed against the fluff and has a preset gap with the surface to be cleaned.

[0075] That is to say, the design of the auxiliary wheel 14 can not only prevent the remaining structures of the mopping assembly 100 from contacting and generating friction with the surface to be cleaned, but also can ensure that there is a preset gap between the flexible isolation member and the ground when the flexible isolation member is in the isolation position, thereby preventing the flexible isolation member from contacting and generating friction with the surface to be cleaned.

[0076] It should be noted that the mopping assembly 100 may also include a drive structure 4, which is arranged on the mopping bracket 1 to drive the transmission structure 3 to drive the isolation member 2 to move. Among them, the drive structure 4 is preferably a motor, and the output shaft of the motor is simultaneously connected to the synchronous pulleys 32 corresponding to the two synchronous belts 31. Of course, the above-mentioned drive structure can also be arranged on the body of the cleaning robot, and the transmission structure and the drive structure are detachably connected. When the mopping assembly is installed on the body, the drive structure and the transmission structure are connected. When the mopping assembly is removed from the body, the drive structure and the transmission structure are disconnected. At this time, the drive structure is preferably a motor, and the output shaft of the motor is simultaneously connected to the synchronous pulleys corresponding to the two synchronous belts. In this case, the coaxial synchronous pulleys corresponding to the two synchronous belts are connected, and the output shaft of the TV is detachably connected to the synchronous pulley corresponding to one of the synchronous belts.

[0077] For example, in a specific implementation, referring to Figure 5 The mop is a crawler-type mop. The mop bracket 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is provided with a first rotating shaft 111, which extends along the length of the mop. The second bracket 12 is provided with a second rotating shaft 121 parallel to the first rotating shaft 111. The mop is wound around the first rotating shaft 111 and the second rotating shaft 121. The mop can be rotated by the first rotating shaft 111 or the second rotating shaft 121 to clean the surface to be cleaned.

[0078] The first bracket 11 is provided with synchronous wheels 32 at both ends of the first rotating shaft 111 in the axial direction. The support shaft 33 is rotatably provided on the second bracket 12. The support shaft 33 is provided with one, and the support shaft 33 is parallel to the first rotating shaft 111. In the first direction, the second rotating shaft 121 is located between the support shaft 33 and the first rotating shaft 111. The support shaft 33 is provided with synchronous wheels 32 at both ends of its axial direction. The support shaft 33 and the synchronous wheels 32 can rotate synchronously and are rotatably provided on the second bracket 12. At this time, each synchronous belt 31 is supported by two synchronous wheels 32. The length direction of the mop is as follows: Figure 5 The X direction in the first direction is perpendicular to the length direction of the mop, such as Figure 5 in the Y direction.

[0079] Furthermore, the first bracket 11 is provided with auxiliary wheels 14 at both axial ends of the first rotating shaft 111. The auxiliary wheels 14 are coaxial with the synchronous wheels 32 located at both ends of the first rotating shaft 111. The second bracket 12 is provided with auxiliary wheels 14 at both axial ends of the support shaft 33. The auxiliary wheels 14 are coaxial with the synchronous wheels 32 located at both ends of the support shaft 33. The diameter of the auxiliary wheels 14 is larger than that of the synchronous wheels 32. Thus, when the auxiliary wheels 14 come into contact with the surface to be cleaned, the synchronous wheels 32 maintain a certain distance from the surface to be cleaned, preventing friction caused by contact between the synchronous belt 31 and the flexible isolation member and the surface to be cleaned.

[0080] In this case, refer to Figure 5 The above-mentioned support shaft 33 is fixedly connected to a synchronous wheel 32 at both ends in its axial direction, and an extension shaft 331 is extended outward. The two extension shafts 331 are rotatably set on the second bracket 12, and the auxiliary wheel 14 is sleeved on the extension shaft 331 and can rotate relative to the extension shaft 331.

[0081] It should be noted that the first bracket 11 and the second bracket 12 can be integrally formed, or can be two independent components connected into one.

[0082] Furthermore, the mopping assembly 100 further includes a driving structure 4 , which is preferably a motor, and an output shaft of the motor is connected to one of the extension shafts 331 .

[0083] It should be noted that, referring to Figure 5 The mopping bracket 1 is composed of a first bracket 11 and a second bracket 12, and the support shaft 33 and the second rotating shaft 121 are both arranged on the second bracket 12. Figures 6 and 7 Alternatively, the mopping bracket 1 may be composed of a first bracket 11, a second bracket 12, and a third bracket 13, wherein the second rotating shaft 121 is disposed on the second bracket 12, and the supporting shaft 33 is disposed on the third bracket 13, and the second bracket 12 and the third bracket 13 are connected. The connection method may be a detachable connection method such as screws or clamping, or a fixed connection method such as welding or fusion, which will not be described in detail here.

[0084] For example, in another specific implementation, the mop is a roller mop. The roller mop is rotatably mounted on a mopping bracket. In this case, the mopping bracket may include a first bracket and a second bracket. The roller mop is rotatably mounted on the first bracket. The first bracket is provided with synchronous pulleys at both ends of the roller mop's axial direction, that is, at both ends in the length direction of the mop. The second bracket is provided with synchronous pulleys rotatable relative to the second bracket. A synchronous belt is wound around the synchronous pulleys on the first bracket and the second bracket.

[0085] In addition, auxiliary wheels are installed at both ends of the roller mop's axial direction on the first bracket. The auxiliary wheels are coaxial with the synchronous wheel on the first bracket. The second bracket is also equipped with auxiliary wheels. The auxiliary wheels are coaxial with the synchronous wheel on the second bracket. The diameter of the auxiliary wheels is larger than that of the synchronous wheel. When the auxiliary wheels come into contact with the surface to be cleaned, the synchronous wheels maintain a certain distance from the surface to be cleaned, preventing friction caused by the synchronous belt contacting the surface.

[0086] It should be noted that the first bracket and the second bracket can be integrally formed, or can be two independent components connected into one.

[0087] Furthermore, the above-mentioned mopping assembly also includes a driving structure, which is preferably a motor, and the output shaft of the motor simultaneously drives the synchronous wheel on the second bracket or simultaneously drives the synchronous wheel on the first bracket.

[0088] In some embodiments, the isolating member is a flexible isolating member, which is supported on the transmission structure and switches between an isolating position and an avoidance position along with the transmission structure.

[0089] The flexible isolating member may be a plastic film, such as a PET film, or a rubber film, which is not specifically limited here.

[0090] The above-mentioned transmission structure includes a pulling member and a winding member. The pulling member drives the flexible isolation member to move on the lower side of the mop to support the flexible isolation member on the lower side of the mop so that the flexible isolation member is in an isolation position. The winding member can wind up the flexible isolation member when the pulling member stops driving so that the flexible isolation member is in an avoidance position.

[0091] It is understandable that when the flexible isolating member is in the isolating position, it is located at the lower side of the mop, and when the flexible isolating member is in the avoiding position, the flexible isolating member is wound around the winding member to avoid the mop.

[0092] Exemplarily, the winding member includes a reel, which is rotatably disposed on the mopping bracket and extends along the length direction of the mop. One end of the flexible isolator is fixed on the reel, and the flexible isolator is wound on the reel when in the avoidance position.

[0093] The pulling member may include a connecting belt and a rotating shaft. The rotating shaft is rotatably mounted on the mopping bracket and extends along the length of the mop, with the mop positioned between the rotating shaft and the reel. Two connecting belts are provided, one at each end of the mop's length. One end of the connecting belt is connected to and wound around the rotating shaft, and the other end is connected to the free end of the flexible isolation member.

[0094] When the shaft rotates, the connecting belt is retracted to drive the flexible isolation member to unfold and move under the mop, and finally move to the isolation position. When the reel rotates, the flexible isolation member is retracted, causing the isolation membrane to move from the isolation position to the avoidance position. During this process, the connecting belt is driven to unfold.

[0095] It should be noted that while the reel is retracting the flexible spacer, the shaft also needs to rotate to release the connecting belt, meaning the shaft needs to stop retracting the connecting belt. Furthermore, when the shaft retracts the connecting belt and drives the flexible spacer to the underside of the mop, the reel also needs to rotate to release the flexible spacer, meaning the reel needs to stop retracting the flexible spacer. Thus, the reel and shaft need to rotate simultaneously to move the flexible spacer.

[0096] Of course, the rotating shaft of the pulling member can also be replaced by two wheels. In this case, the two wheels can rotate synchronously, and the two wheels are respectively located at the two ends of the mop in the length direction, and the two connecting belts are respectively wound on the two wheels.

[0097] The mopping assembly may further include a driving structure, which is arranged on the mopping bracket to drive the transmission structure to move the isolation member. In this case, the driving structure includes two driving members, and the reel and the rotating shaft can be driven by two driving members arranged on the mopping bracket respectively. Alternatively, the driving structure can also be arranged on the body of the cleaning robot, and the driving structure and the transmission structure can be detachably connected. When the mopping assembly is installed on the body, the driving structure can drive the reel and the pulling member to realize the switching of the isolation member between the avoidance position and the isolation position. For example, the driving structure includes two driving members, and both driving members are arranged on the body of the cleaning robot. In this case, the rotating shaft and the corresponding driving member are detachably connected, and the reel and the corresponding driving member are detachably connected. Wherein, the driving member is preferably a motor.

[0098] Exemplarily, the mopping assembly may further include auxiliary wheels that can rotate around their own axes. Auxiliary wheels are provided at both ends of the mopping bracket in the length direction of the mop. The mop is located between the auxiliary wheels at both ends of the mopping bracket, and the auxiliary wheels are used to contact the ground.

[0099] It can be understood that the mopping assembly supports the mopping assembly by contacting the surface to be cleaned with the auxiliary wheels, so that when the mop is mopping the surface to be cleaned, the auxiliary wheels can keep a certain distance between the remaining structure of the mopping assembly and the surface to be cleaned, thereby avoiding friction damage caused by contact between the remaining structure of the mopping assembly and the surface to be cleaned.

[0100] The above-mentioned mop includes a base and fluff arranged on the base and capable of mopping the surface to be cleaned. When the flexible isolator is in the avoidance position, the fluff contacts the surface to be cleaned and can be mopped. When the flexible isolator is in the isolation position, the flexible isolator is pressed against the fluff and has a preset gap with the surface to be cleaned.

[0101] In other words, the design of the auxiliary wheels can not only prevent the rest of the structure of the mopping assembly from contacting and generating friction with the surface to be cleaned, but also ensure that when the flexible isolation member is in the isolation position, there is a preset gap between the flexible isolation member and the ground, thereby preventing the flexible isolation member from contacting and generating friction with the surface to be cleaned.

[0102] For example, in a specific implementation, the mop is a crawler-type mop. The mop bracket includes a first bracket and a second bracket. The first bracket is provided with a first rotating shaft, which extends along the length of the mop. The second bracket is provided with a second rotating shaft. The mop is wound around the first rotating shaft and the second rotating shaft. The mop can be rotated by the first rotating shaft or the second rotating shaft to clean the surface to be cleaned.

[0103] The rotating shaft is rotatably arranged on the first bracket, and the reel is rotatably arranged on the second bracket. The first rotating shaft and the second rotating shaft are both located between the rotating shaft and the reel.

[0104] Furthermore, auxiliary wheels are mounted on both ends of the first bracket's rotating shaft, allowing them to rotate relative to the first bracket. These auxiliary wheels are coaxial with the rotating shaft and have a larger diameter than the shaft. The second bracket also has auxiliary wheels mounted on both ends of the reel's axial direction, allowing them to rotate relative to the second bracket. These auxiliary wheels are coaxial with the reel and have a larger diameter than the reel. This allows the reel and rotating shaft to maintain a certain distance from the surface being cleaned when the auxiliary wheels come into contact, preventing friction between the connecting belt and the flexible spacer and the surface.

[0105] It should be noted that the first bracket and the second bracket can be integrally formed, or can be two independent components connected into one.

[0106] For example, in another specific implementation, the mop is a roller mop. The roller mop is rotatably mounted on a mopping bracket. In this case, both the reel and the rotating shaft are mounted on the mopping bracket, and the roller mop is located between the reel and the rotating shaft.

[0107] The mopping bracket is equipped with auxiliary wheels at both ends of the rotating shaft, which can rotate relative to the mopping bracket. The auxiliary wheels are coaxial with the rotating shaft and have a larger diameter than the rotating shaft. The mopping bracket is also equipped with auxiliary wheels at both ends of the reel, which can rotate relative to the mopping bracket. The auxiliary wheels are coaxial with the reel and have a larger diameter than the reel. This allows the reel and rotating shaft to maintain a certain distance from the surface to be cleaned when the auxiliary wheels come into contact with the surface, preventing friction caused by contact between the connecting belt and the flexible spacer.

[0108] In some embodiments, the isolation member is an isolation plate, the transmission structure is a linear telescopic transmission member, and the isolation plate is connected to the linear telescopic transmission member.

[0109] It can be understood that the isolation member is an isolation plate. At this time, the isolation plate can move linearly under the action of the linear telescopic transmission member to move to the isolation position on the lower side of the mop so as to separate the mop from the surface to be cleaned, and leave the avoidance position between the lower side of the mop and the surface to be cleaned so that the mop contacts the surface to be cleaned.

[0110] Exemplarily, the above-mentioned linear telescopic transmission member can be selected as the telescopic rod of an electric push rod, which is arranged on the mopping bracket, and the telescopic rod of the electric push rod is connected to the isolation plate. The extension and contraction of the telescopic rod drives the isolation plate to switch between the isolation position and the avoidance position.

[0111] In addition, when the isolating member is selected as an isolation plate, the above-mentioned isolating member and the transmission structure can also be all arranged on the body of the cleaning robot. At this time, the body of the cleaning robot needs to be provided with a space for accommodating the isolation plate when in the avoidance position.

[0112] The transmission structure can be a linear telescopic transmission member, such as a telescopic rod, which can be extended or retracted under the drive of the drive structure. The drive structure and the linear telescopic transmission member together constitute an electric push rod. Alternatively, the transmission structure can be a meshing gear and rack, with the rack disposed on the isolation plate and the gear connected to a drive member, such as a motor. The drive member drives the gear to rotate, thereby driving the rack to move along the extension direction of the rack itself, thereby achieving linear movement of the isolation member to switch between the avoidance position and the isolation position.

[0113] It should be noted that the mop can be either a crawler-type mop or a roller-type mop. In the case of a crawler-type mop, the mopping bracket includes a first bracket and a second bracket, wherein the first bracket is provided with a first rotating shaft, and the second bracket is provided with a second rotating shaft. The mop is wound around the first rotating shaft and the second rotating shaft, and the mop can rotate under the drive of the first rotating shaft or the second rotating shaft to clean the surface to be cleaned. The isolation plate can be slidably mounted on the first bracket or the second bracket, and the linear telescopic drive member is co-mounted with the isolation plate on the first bracket or the second bracket.

[0114] When the mop is a roller mop, the mopping bracket may include a first bracket and a second bracket, the roller mop is rotatably arranged on the first bracket, the isolation plate is slidably arranged on the second bracket, and the linear telescopic transmission member is arranged on the second bracket.

[0115] In some embodiments, the mopping assembly further includes a driving structure, which is disposed on the mopping bracket to drive the transmission structure to move the isolation member.

[0116] It is understandable that the mopping assembly is equipped with a driving structure that enables the isolation member to switch between the avoidance position and the isolation position. The driving structure is provided on the mopping bracket.

[0117] For example, in a specific implementation, referring to Figure 8 and Figure 9 The above-mentioned isolation member 2 is a flexible isolation member, which is supported on the transmission structure 3 and switches between the isolation position and the avoidance position with the transmission structure 3.

[0118] Reference Figure 8 The transmission structure 3 includes two synchronous belts 31, which are respectively arranged at both ends of the mop in the length direction. The flexible isolation member is supported between the two synchronous belts 31. The synchronous rotation of the two synchronous belts 31 can drive the flexible isolation member to switch between the upper side and the lower side of the mop, so that the flexible isolation member can switch between the isolation position and the avoidance position.

[0119] Furthermore, the transmission structure 3 further includes a synchronous wheel 32 . At least two synchronous wheels 32 are provided on the mopping bracket 1 corresponding to each synchronous belt 31 , and the synchronous belt 31 is wound around the at least two synchronous wheels 32 .

[0120] Optionally, the transmission structure 3 further includes a support shaft 33 for supporting the flexible isolation member, the support shaft 33 being provided on the mopping bracket 1 and extending along the length direction of the mop cloth. The flexible isolation member is mounted on the support shaft 33 when switching between the avoidance position and the isolation position.

[0121] It should be noted that the support shaft 33 may be located between the synchronous wheels 32 that respectively drive the two synchronous belts 31 , and the support shaft 33 may rotate synchronously with the synchronous wheels 32 , or the support shaft 33 may rotate freely to provide support for the flexible isolation member.

[0122] When there is one support shaft 33, the forward rotation of the synchronous belt 31 causes the flexible isolator to move from the avoidance position to the isolation position, while the reverse rotation causes the flexible isolator to move from the isolation position to the avoidance position. The flexible isolator is placed on the support shaft 33 during the movement. The forward rotation and the reverse rotation are clockwise and counterclockwise respectively, which are not specifically limited here. When there are two support shafts 33, the two support shafts 33 are spaced apart in a direction perpendicular to the length of the mop. At this time, the synchronous belt 31 can rotate in one direction to switch the flexible isolator between the isolation position and the avoidance position. The flexible isolator is placed on one of the support shafts 33 when moving from the isolation position to the avoidance position, and is placed on the other support shaft 33 when moving from the avoidance position to the isolation position.

[0123] The driving structure 4 is provided on the mopping bracket 1 to drive the transmission structure 3 to move the isolation member 2. The driving structure 4 is preferably a motor, and the output shaft of the motor is simultaneously connected to the synchronous pulleys 32 corresponding to the two synchronous belts 31.

[0124] Specifically, the above mop can be a crawler mop or a roller mop. Take the crawler mop as an example, refer to Figure 8 and Figure 9The mopping bracket 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is provided with a first rotating shaft 111, and the first rotating shaft 111 extends along the length direction of the mop. The second bracket 12 is provided with a second rotating shaft 121 parallel to the first rotating shaft 111. The mop is wound around the first rotating shaft and the second rotating shaft. The mop can rotate under the drive of the first rotating shaft or the second rotating shaft to clean the surface to be cleaned.

[0125] The first bracket 11 is provided with synchronous pulleys 32 at both ends of the first rotating shaft 111 in the axial direction. The support shaft 33 is rotatably mounted on the second bracket 12. One support shaft 33 is provided, and the support shaft 33 is parallel to the first rotating shaft 111. The second rotating shaft 121 is located between the support shaft 33 and the first rotating shaft 111 in a direction perpendicular to the length of the mop. The support shaft 33 is provided with synchronous pulleys 32 at both ends of its axial direction. The support shaft 33 and the synchronous pulleys 32 can rotate synchronously and are rotatably mounted on the mopping bracket 1. In this case, each synchronous belt 31 is supported by two synchronous pulleys 32.

[0126] In this case, refer to Figure 8 The above-mentioned support shaft 33 is fixedly connected to a synchronous wheel 32 at both ends in its axial direction, and an extension shaft is provided outwardly. The two extension shafts are rotatably provided on the second bracket 12, and the auxiliary wheel 14 is sleeved on the extension shaft and can rotate relative to the extension shaft.

[0127] It should be noted that the first bracket 11 and the second bracket 12 can be integrally formed, or can be two independent components connected into one.

[0128] The driving structure 4 is connected to one of the extension shafts, which can drive the support shaft 33 to rotate, and at the same time drive the two synchronous wheels 32 connected to the support shaft 33 to rotate, thereby driving the two synchronous belts 31 to drive the flexible isolation member to switch between the isolation position and the avoidance position.

[0129] For example, in another specific implementation, the isolation member is an isolation plate, the transmission structure is a linear telescopic transmission member, and the isolation plate is connected to the end of the linear telescopic transmission member.

[0130] The mop can be either a crawler-type mop or a roller-type mop. In the case of a crawler-type mop, the mopping bracket includes a first bracket and a second bracket. The first bracket is provided with a first rotating shaft, and the second bracket is provided with a second rotating shaft. The mop is wound around the first and second rotating shafts and can rotate to clean the surface to be cleaned under the drive of the first or second rotating shaft. The isolation plate can be slidably mounted on the first or second bracket, and the linear telescopic drive member is co-mounted with the isolation plate on the first or second bracket.

[0131] In this case, the drive structure and the linear telescopic drive member are jointly arranged on the first bracket or the second bracket. For example, the linear telescopic drive member is a telescopic rod. In this case, the telescopic rod can be extended or retracted under the drive structure, and the drive structure and the linear telescopic drive member together constitute the electric push rod.

[0132] When the mop is a roller mop, the mopping bracket may include a first bracket and a second bracket, the roller mop is rotatably arranged on the first bracket, the isolation plate is slidably arranged on the second bracket, and the linear telescopic transmission member is arranged on the second bracket.

[0133] At this time, the driving structure is arranged on the second bracket. For example, the linear telescopic transmission member is selected as a telescopic rod. In this case, the telescopic rod can be extended or retracted under the drive of the driving structure. The driving structure and the linear telescopic transmission member together constitute the electric push rod.

[0134] An embodiment of the present application provides a cleaning robot, which includes a body and the above-mentioned mopping component. A component assembly cavity for accommodating the mopping component is provided on the bottom surface of the body.

[0135] An ultrasonic sensor is installed at the bottom of the device. It uses the differences in acoustic wave absorption, resulting in echo differences, to accurately identify materials such as flooring and carpet. When carpet is detected, the controller controls the drive mechanism, which drives the isolation member through a transmission structure, to move the isolation member to an isolated position, protecting the carpet.

[0136] In some embodiments, reference Figures 10 to 12 The mopping assembly 100 further includes a first clamping structure 16 disposed on the mopping bracket 1 , and the body 200 is provided with a second clamping structure 7 that can be engaged with and disengaged from the first clamping structure 16 .

[0137] It can be understood that the first clamping structure 16 and the second clamping structure 7 can be used to achieve relative fixation of the mopping assembly 100 and the body 200 when the mopping assembly 100 is installed in the assembly assembly cavity 2001 on the body 200.

[0138] For example, referring to Figure 10 and Figure 11 The first clamping structure 16 includes a pressing element 161 and a pressing elastic member 162. The mopping bracket 1 is provided with an installation channel. The pressing elastic member 162 is arranged in the installation channel and is limited between the pressing element 161 and the cavity wall of the installation channel. The pressing element 161 is slidably arranged in the installation channel. Figure 12The second engaging structure 7 can be a locking hole. The pressing element 161 has a first position and a second position relative to the mopping bracket 1. When the pressing element 161 is in the first position, it is engaged with the locking hole. When the pressing element 161 is in the second position, it is disengaged from the locking hole. The pressing element 161 can be moved from the first position to the second position by an external force, compressing the pressing elastic member 162 during the process. When the pressing element 161 is in the second position and is not subjected to an external force, the pressing element 161 moves from the second position to the first position under the action of the pressing elastic member 162.

[0139] Thus, when the mopping assembly 100 is installed, the pressing element 161 is located in the first position. After the pressing element 161 contacts the body 200, the pressing element 161 is moved to the second position by the body 200. After the pressing element 161 and the latch hole are aligned, the pressing element 161 is moved to the first position under the action of the pressing elastic member 162 to engage with the latch hole, thereby completing the assembly of the mopping assembly 100 and the body 200. The pressing element 161 is provided with a guide bevel. The guide bevel is configured so that after the pressing element 161 contacts the body 200 and the mopping assembly 100 is pressed, the pressing element 161 is subjected to a force in a direction from the first position to the second position under the action of the guide bevel, causing it to move to the second position. When the mopping assembly 100 is disassembled, the pressing element 161 is pressed through the latch hole so that the pressing element 161 moves to the second position and disengages from the latch hole, and the mopping assembly 100 can be disassembled from the body 200 .

[0140] It should be noted that to prevent the pressing element 161 from being separated from the installation channel, a limiting buckle 1611 can be provided on the pressing element 161, and a limiting hole 122 connected to the installation channel is provided on the mopping bracket 1. When installing the pressing element 161, the pressing element 161 is inserted into the installation channel in a direction from the first position to the second position. At this time, the limiting buckle 1611 moves toward the center of the installation channel under the pressure of the installation channel wall and produces elastic deformation. When the limiting buckle 1611 moves to the position of the limiting hole 122, the limiting buckle 1611 extends into the limiting hole 122 under the action of its own elastic force, thus completing the installation of the pressing element 161. The limiting buckle 1611 cooperates with the hole wall of the limiting hole 122 to limit the pressing element 161 when it moves to the first position.

[0141] Furthermore, the first clamping structure 16 and the second clamping structure 7 are both provided with two, and the two first clamping structures 16 on the mopping bracket 1 are respectively located on both sides of the length direction of the mop 5. The two first clamping structures 16 and the two second clamping structures 7 cooperate with each other to improve the installation stability of the mopping assembly 100. Figure 10 The X direction shown in .

[0142] For example, the mopping bracket may be provided with a plug-in shaft, and the body may be provided with a socket or slot for inserting the plug-in shaft, and the plug-in shaft may rotate in the socket or slot, or the plug-in shaft may drive the structure provided with the socket or slot on the body to rotate synchronously, so that the mopping assembly as a whole may rotate relative to the body so that the first clamping structure and the second clamping structure are clamped.

[0143] That is to say, the mopping assembly and the body are initially fixed by the cooperation of the plug-in shaft and the socket (or slot), and then the mopping assembly is rotated relative to the body to finally be assembled with the first clamping structure and the second clamping structure.

[0144] In one case, the plug-in axis is defined as the first plug-in axis 17, with reference to Figure 11 and Figure 12 The above-mentioned first plug-in shaft 17 can be a structure for connecting a rotating shaft that can drive the mop 5 to rotate. The first plug-in shaft 17 is used to connect with the driving component 10 on the body 200 that can drive the rotating shaft to rotate. In this way, after the first plug-in shaft 17 and the socket 9 are plugged in, not only can the preliminary positioning of the mopping component 100 and the body 200 be achieved, but also the connection between the rotating shaft and the driving component 10 is achieved, so that after the mopping component 100 is installed, the mop can be driven by the driving component 10 to rotate to mop the surface to be cleaned.

[0145] The drive assembly 10 can be a motor and a gear connected to the motor, and the gear is provided with the aforementioned socket 9. In this case, the socket and the first plug shaft 17 need to be able to rotate synchronously after being plugged in. Therefore, the first plug shaft 17 and the socket 9 are both provided with a fittable anti-rotation limit surface. For example, the first plug shaft 17 is a square shaft, and the socket 9 is a square hole that matches the first plug shaft 17.

[0146] In another case, the plug-in axis is defined as the second plug-in axis 18, with reference to Figures 10 to 14 , the above-mentioned second plug-in shaft 18 can be selected as a flat shaft, the flat shaft has two parallel planes in the second direction, two arc surfaces in the third direction, an arc surface between the two planes, and the two planes have a preset distance in the second direction. The above-mentioned body 200 is provided with a plug-in slot 8, and the plug-in slot 8 is composed of a circular slot 81 and a linear slot 82 that are connected, and the width of the linear slot 82 is smaller than the diameter of the circular slot 81. One end of the linear slot 82 is connected to the circular slot 81, and the other end is provided with an opening for inserting the flat shaft. Among them, the width of the linear slot 82 is greater than or equal to the above-mentioned preset distance, and the maximum width of the flat shaft in the third direction is greater than the width of the linear slot 82. In this way, during installation, the flat shaft is inserted into the linear slot 82 from the opening and moved into the circular slot 81, as shown Figure 13Then rotate the flat shaft so that the third direction of the flat shaft coincides with the width of the linear slot 82. At this time, the maximum width of the flat shaft in the third direction is greater than the width of the linear slot 82. The flat shaft cannot be removed from the insertion slot 8 and is confined to the circular slot 81. Figure 14 shown.

[0147] It should be noted that the second direction is perpendicular to the third direction, that is, the flat shaft is fixed in the circular groove 81 after rotating 90 degrees in the circular groove 81. In addition, when the flat shaft is fixed in the circular groove 81, the first clamping structure 16 and the second clamping structure 7 are clamped.

[0148] For example, referring to Figure 10 and Figure 12 The mopping bracket 1 is provided with two plug-in shafts, one of which is a first plug-in shaft 17 and the other is a second plug-in shaft 18 .

[0149] Specifically, taking a crawler-type mop as an example, the mopping bracket 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is provided with a first rotating shaft 111, and the second bracket 12 is provided with a second rotating shaft 121 parallel to the first rotating shaft 111. The mop 5 is wound around the first rotating shaft 111 and the second rotating shaft 121. The mop 5 can rotate under the drive of the first rotating shaft 111 to clean the surface to be cleaned.

[0150] The first rotating shaft 111 has the first plug-in shaft 17 at one end thereof and the second plug-in shaft 18 at the other end. The first clamping structure 16 is provided on the second bracket 12. Thus, the first plug-in shaft 17 cooperates with the socket 9 and the second plug-in shaft 18 cooperates with the plug-in slot 8, thereby achieving a preliminary connection between the mopping assembly 100 and the machine body 200. Figure 15 Then rotate and press the mopping assembly 100 so that the first clamping structure 16 and the second clamping structure 7 are clamped together to achieve the installation of the mopping assembly 100, as shown. Figure 16 shown.

[0151] In some embodiments, reference Figures 17 to 22 The cleaning robot further includes a driving structure 4 disposed on the body 200 , and the driving structure 4 can drive the transmission structure 3 to drive the isolation member 2 to move.

[0152] It can be understood that the driving structure 4 that provides power for the movement of the isolation member 2 is arranged on the body 200 of the cleaning robot. This requires that the driving structure 4 and the transmission structure 3 are detachably connected. When the mopping component 100 is installed in the component assembly cavity 2001, the driving structure 4 and the transmission structure 3 are connected in transmission, and the driving structure 4 can drive the isolation member 2 to move through the transmission structure 3.

[0153] Furthermore, it also includes a connecting structure 6, which includes a first transmission member 61 and a second transmission member 62. The first transmission member 61 is connected to the driving structure 4, and the second transmission member 62 is connected to the transmission structure 3. The first transmission member 61 and the second transmission member 62 are detachably connected.

[0154] For example, in one embodiment, the first and second transmission members can transmit rotation. For example, both can be bevel gears, which allows for both transmission and change of direction. Alternatively, both can be drive shafts, which allows for only transmission without changing the direction of rotation. Alternatively, one can be a worm and the other a worm wheel, which allows for both transmission and change of direction.

[0155] In another case, the above-mentioned first transmission member and second transmission member can also convert rotation into linear movement. For example, the first transmission member and the second transmission member are a gear and a rack respectively, which can convert the rotation of the gear into the linear movement of the rack, and also convert the linear movement of the rack into the rotation of the gear.

[0156] It should be noted that the first transmission member and the second transmission member can be selected according to actual transmission requirements and are not listed here one by one.

[0157] For example, referring to Figures 17 to 20 , the transmission structure 3 and the driving structure 4 are connected by two bevel gears to realize the transmission of rotation. At this time, the driving structure 4 is selected as a motor.

[0158] Specifically, taking the isolator 2 as a flexible isolator as an example, for ease of description, the two bevel gears are defined as a first bevel gear and a second bevel gear, respectively. The driving structure 4 is a motor provided on the body 200, the output shaft of the motor is connected to the first bevel gear, and the second bevel gear is connected to the transmission structure 3.

[0159] Among them, the above-mentioned transmission structure 3 includes two synchronous belts 31, which are respectively arranged at both ends of the mop 5 along the length direction. The flexible isolation member is supported between the two synchronous belts 31. The synchronous rotation of the two synchronous belts 31 can drive the flexible isolation member to switch between the upper and lower sides of the mop 5, so that the flexible isolation member can switch between the isolation position and the avoidance position.

[0160] Furthermore, the transmission structure 3 further includes a synchronous wheel 32 . At least two synchronous wheels 32 are provided on the mopping bracket 1 corresponding to each synchronous belt 31 , and the synchronous belt 31 is wound around the at least two synchronous wheels 32 .

[0161] It should be noted that at least two synchronous wheels 32 are arranged in sequence in the first direction, and the first direction is perpendicular to the length direction of the mop 5. Figure 17 The X direction shown in the first direction is as follows Figure 17 Y direction shown in .

[0162] At this time, the second bevel gear is connected to the synchronous pulleys 32 corresponding to the two synchronous belts 31, and can drive the two synchronous belts 31 to rotate synchronously through the synchronous pulleys 32. For example, each synchronous belt 31 is supported by two synchronous pulleys 32. For ease of description, the synchronous pulleys corresponding to each synchronous belt 31 are defined as the first synchronous pulley and the second synchronous pulley. The two first synchronous pulleys are coaxial and can rotate synchronously, and the two second synchronous pulleys are coaxial and can rotate synchronously. The second bevel gear is connected to the two first synchronous pulleys.

[0163] Optionally, the transmission structure 3 further includes a support shaft 33 for supporting the flexible isolation member, the support shaft 33 being provided on the mopping bracket 1 and extending along the length direction of the mop cloth. The flexible isolation member is mounted on the support shaft 33 when switching between the avoidance position and the isolation position.

[0164] It should be noted that both ends of the support shaft 33 are connected to the synchronous wheel 32, and the support shaft 33 can rotate synchronously with the synchronous wheel 32. At this time, the second bevel gear is connected to the synchronous wheel 32 connected to the support shaft 33 and can rotate synchronously.

[0165] Optionally, the mopping assembly 100 further includes an auxiliary wheel 14 that can rotate around its own axis. The mopping bracket 1 is provided with auxiliary wheels 14 at both ends in the length direction of the mop 5. The mop 5 is located between the auxiliary wheels 14 at both ends of the mopping bracket 1, and the auxiliary wheels 14 are used to contact the ground.

[0166] The above-mentioned mop 5 includes a base and fluff arranged on the base and capable of mopping the surface to be cleaned. When the flexible isolator is in the avoidance position, the fluff contacts the surface to be cleaned and can be mopped. When the flexible isolator is in the isolation position, the flexible isolator is pressed against the fluff and has a preset gap with the surface to be cleaned.

[0167] Further, refer to Figures 17 to 20 The mopping bracket 1 is provided with a cover 15 to cover the connecting structure 6 at the lower side of the body 200 when the first transmission member 61 and the second transmission member 62 are connected.

[0168] It can be understood that by providing the cover 15, after the mopping component 100 is installed in the component assembly cavity 2001, the cover 15 can cover the connecting structure 6 on the lower side of the body 200, thereby preventing dust and dirt from affecting the operation of the two bevel gears, and also preventing the user from being scratched by the bevel gears when carrying the body 200 again.

[0169] Reference Figures 17 to 22The mopping assembly 100 may further include a first clamping structure 16 provided on the mopping bracket 1, and a second clamping structure 7 which can be engaged with and disengaged from the first clamping structure 16 is provided on the body 200. The first clamping structure and the second clamping structure may be selected as follows: Figures 10 to 12 The structure in will not be described here.

[0170] It can be understood that the first clamping structure 16 and the second clamping structure 7 can be used to achieve relative fixation of the mopping assembly 100 and the body 200 when the mopping assembly 100 is installed in the assembly assembly cavity 2001 on the body 200.

[0171] In addition, the above-mentioned mopping bracket may be provided with a plug-in shaft, and the body may be provided with a socket or slot for the plug-in shaft to be inserted, and the plug-in shaft may rotate in the socket or slot, or the plug-in shaft may drive the structure provided with the socket or slot on the body to rotate synchronously, so that the mopping assembly as a whole can rotate relative to the body to enable the first clamping structure and the second clamping structure to be clamped.

[0172] That is to say, the mopping assembly and the body are initially fixed by the cooperation of the plug-in shaft and the socket (or slot), and then the mopping assembly is rotated relative to the body to finally be assembled with the first clamping structure and the second clamping structure.

[0173] In one case, the plug-in axis is defined as the first plug-in axis 17, with reference to Figure 17 and Figure 18 The above-mentioned first plug-in shaft 17 can be a structure for connecting a rotating shaft that can drive the mop 5 to rotate. The first plug-in shaft 17 is used to connect with the driving component 10 on the body 200 that can drive the rotating shaft to rotate. In this way, after the first plug-in shaft 17 and the socket are plugged in, not only the preliminary positioning of the mopping component 100 and the body 200 can be achieved, but also the connection between the rotating shaft and the driving component 10 can be achieved, so that after the mopping component 100 is installed, the mop 5 can be driven by the driving component 10 to rotate to mop the surface to be cleaned.

[0174] The drive assembly 10 can be a motor and a gear connected to the motor, with the aforementioned jack being provided on the gear. The jack and the first plug shaft 17 need to be able to rotate synchronously after being plugged in, so both the first plug shaft 17 and the jack are provided with a fittable anti-rotation limit surface. For example, the first plug shaft 17 is a square shaft, and the jack is a square hole that fits the first plug shaft 17.

[0175] In another case, the plug-in axis is defined as the second plug-in axis 18, with reference to Figure 17 and Figure 18The second plug-in shaft 18 can be selected as a flat shaft. The flat shaft has two parallel planes in the second direction and two arc surfaces in the third direction. There is an arc surface between the two planes, and the two planes have a preset distance in the second direction. The body 200 is provided with a plug-in slot, which consists of a circular slot and a linear slot that are connected, and the width of the linear slot is smaller than the diameter of the circular slot. One end of the linear slot is connected to the circular slot, and the other end is provided with an opening for inserting the flat shaft. The width of the linear slot is greater than or equal to the preset distance, and the maximum width of the flat shaft in the third direction is greater than the width of the linear slot. In this way, during installation, the flat shaft is inserted into the linear slot from the opening and moved into the circular slot. The flat shaft is then rotated so that the third direction of the flat shaft coincides with the width of the linear slot. At this time, the maximum width of the flat shaft in the third direction is greater than the width of the linear slot. The flat shaft cannot be moved out of the plug-in slot and is confined in the circular slot.

[0176] It should be noted that the second direction is perpendicular to the third direction, that is, the flat shaft is limited in the circular groove after rotating 90 degrees in the circular groove. In addition, when the flat shaft is limited in the circular groove, the first clamping structure and the second clamping structure are clamped.

[0177] For example, referring to Figure 17 and Figure 18 Two plug-in shafts are provided on the mopping bracket 1 , one of which is a first plug-in shaft 17 and the other is a second plug-in shaft 18 .

[0178] Specifically, take the mop 5 as a crawler mop and the isolation room as a flexible isolation member as an example. Figure 17 and Figure 18 The mopping bracket 1 includes a first bracket 11, a second bracket 12, and a third bracket 13. The first bracket 11 is connected to the second bracket 12, and the second bracket 12 is connected to the third bracket 13. The first bracket 11 is provided with a first rotating shaft 111, which extends along the length of the mop. The second bracket 12 is provided with a second rotating shaft 121, which is parallel to the first rotating shaft 111. The mop 5 is wound around the first rotating shaft 111 and the second rotating shaft 121. The mop 5 can rotate under the drive of the first rotating shaft 111 or the second rotating shaft 121 to clean the surface to be cleaned.

[0179] The first bracket 11 is provided with synchronous pulleys 32 at both ends of the first rotating shaft 111 in the axial direction. The support shaft 33 is rotatably mounted on the third bracket 13. The support shaft 33 is provided with one, and the support shaft 33 is parallel to the first rotating shaft 111. In the first direction, the second rotating shaft 121 is located between the support shaft 33 and the first rotating shaft 111. The support shaft 33 is provided with synchronous pulleys 32 at both ends of its axial direction. The support shaft 33 and the synchronous pulleys 32 can rotate synchronously and are rotatably mounted on the second bracket 12. At this time, each synchronous belt 31 is supported by two synchronous pulleys 32.

[0180] The cover 15 is disposed on the third bracket 13. The cover 15 can be integrally formed with the third bracket 13, or can be separately disposed and connected to the third bracket 13.

[0181] It should be noted that the second bracket 12 and the third bracket 13 are provided as separate parts and connected as a whole. The connection method can adopt a detachable connection method such as screws, clamps, etc. to facilitate the disassembly of the mopping assembly 100. Of course, the second bracket 12 and the third bracket 13 can also be provided as an integral part, in which case the cover 15 is provided on the second bracket.

[0182] The first rotating shaft 111 has the first plug-in shaft 17 at one end thereof and the second plug-in shaft 18 at the other end. The first clamping structure 16 is provided on the second bracket 12. Thus, the first plug-in shaft 17 cooperates with the socket and the second plug-in shaft 18 cooperates with the plug-in slot 8, thereby achieving a preliminary connection between the mopping assembly 100 and the machine body 200. Figure 21 Then rotate and press the mopping assembly 100 so that the first clamping structure 16 and the second clamping structure 7 are clamped, and the cover 15 is covered on the connecting structure 6 to achieve the installation of the mopping assembly 100, as shown. Figure 22 shown.
