[0042] Reference Figures 1-5 As shown, the solution provides a cleaning assembly 1 of a cleaning robot, which includes a support frame 5, a cleaning member 2 disposed on the support frame 5, and a baffle 3, the baffle 3 being movable relative to the support frame 5 between a shielding position and an exposing position, in the shielding position, the baffle 3 at least partially covers a cleaning portion of the cleaning member 2 to avoid the cleaning member 2 from contacting a passing surface that does not need to be cleaned, in the exposing position, the baffle 3 leaves the cleaning portion of the cleaning member 2 to allow the cleaning member 2 to contact a passing surface that needs to be cleaned.

[0043] The cleaning robot can travel on a floor, a carpet, a tile, or the like, which is the passing surface.

[0044] The cleaning assembly 1 can be used to clean the passing surface to remove dirt, dust, hair, or the like, for example, by the cleaning member 2.

[0045] The support frame 5 is the basic structure of the cleaning assembly 1, which can provide a support base for other components, such as the cleaning member 2, the baffle 3, and the like.

[0046] In some cases, some types of passing surfaces do not need to be cleaned, or in other words, cannot be cleaned, and forced cleaning can cause damage to these passing surfaces, such as a carpet, or the like. The passing surface that needs to be cleaned can be a common floor, a tile, or the like.

[0047] The baffle 3 can be moved relative to the support frame 5 between the exposing position and the shielding position, in the shielding position, the baffle 3 at least partially covers the cleaning portion of the cleaning member 2, such that at least a portion of the cleaning portion of the cleaning member 2 is out of contact with the passing surface that does not need to be cleaned, thereby protecting the passing surface that does not need (or cannot) to be cleaned, in the exposing position, the baffle 3 leaves the cleaning portion of the cleaning member 2, such that the cleaning member 2 can contact the passing surface that needs to be cleaned. Figure 2 As shown, the baffle 3 at least partially covers the cleaning portion of the cleaning member 2, such that at least a portion of the cleaning portion of the cleaning member 2 is out of contact with the passing surface that does not need to be cleaned, thereby protecting the passing surface that does not need (or cannot) to be cleaned, in the exposing position, the baffle 3 leaves the cleaning portion of the cleaning member 2, such that the cleaning member 2 can contact the passing surface that needs to be cleaned. Figure 1As shown, the baffle 3 is away from the cleaning part of the cleaning member 2, allowing the cleaning part of the cleaning member 2 to contact the surface to be cleaned, so as to clean the surface to be cleaned by the cleaning part of the cleaning member 2.

[0048] As to the cleaning part of the cleaning member 2, it is the part that can contact the surface to be cleaned, for some types of cleaning member 2, there is movement relative to the support frame 5 during cleaning, the cleaning part of the cleaning member 2 is a specific part relative to the support frame 5, which is constantly changing with the movement of the cleaning member 2, for example, for the cleaning member 2 of the track type, the cleaning part is a specific part relative to the support frame 5, which is constantly changing, and for the cleaning member 2 of the disc type, when the disc is entirely attached to the surface to be cleaned, even if the disc is constantly rotating, its cleaning part remains unchanged.

[0049] In addition, when the baffle 3 is in the shielding position, the baffle 3 can at least partially cover the cleaning part of the cleaning member 2, to block at least part of the cleaning part of the cleaning member 2 from contacting the surface to be cleaned, in the preferred embodiment, the baffle 3 can completely cover the cleaning part of the cleaning member 2, so that the entire cleaning part of the cleaning member 2 cannot contact the surface to be cleaned, to fully protect the surface to be cleaned.

[0050] In this scheme, for the surface to be cleaned or not, the baffle can be moved to the shielding position to isolate the cleaning member from the surface to be cleaned, to avoid the cleaning member from polluting or damaging the surface to be cleaned, so as to better protect the surface to be cleaned and improve the cleaning quality.

[0051] In some embodiments, the cleaning assembly 1 is configured to be raised relative to the main housing of the cleaning robot to disengage from the surface to be cleaned; and the cleaning assembly 1 is configured to be lowered relative to the main housing of the cleaning robot to contact the surface to be cleaned. The cleaning robot can comprise a main housing, when the cleaning robot is supported on the surface to be cleaned, and the cleaning assembly 1 is raised relative to the main housing of the cleaning robot, the distance between the cleaning assembly 1 and the surface to be cleaned is increased and the cleaning assembly 1 is disengaged from the surface to be cleaned, the spacing between the cleaning assembly 1 and the surface to be cleaned can accommodate the insertion of the baffle 3 to the shielding position, and also can allow the baffle 3 to be spaced apart from the surface to be cleaned, avoiding scratching the surface to be cleaned by the baffle 3. When the cleaning robot is supported on the surface to be cleaned, and the cleaning assembly 1 is lowered relative to the main housing of the cleaning robot, the distance between the cleaning assembly 1 and the surface to be cleaned is reduced and begins to gradually contact the surface to be cleaned, of course, the baffle 3 can be moved to the exposed position or kept in the exposed position when the cleaning assembly 1 is lowered, to allow the cleaning element 2 to contact the surface to be cleaned for cleaning as the cleaning assembly 1 is lowered. In which the cleaning assembly 1 can be raised to a first position spaced apart from the surface to be cleaned, which corresponds to the shielding position of the baffle 3, the cleaning assembly 1 can be lowered to a second position in which the cleaning element 2 contacts the surface to be cleaned, which corresponds to the exposed position of the baffle 3; and the upward movement of the cleaning assembly 1 from the second position to the first position corresponds to the movement of the baffle 3 from the exposed position to the shielding position, and the downward movement of the cleaning assembly 1 from the first position to the second position corresponds to the movement of the baffle 3 from the shielding position to the exposed position.

[0052] In some embodiments, the cleaning element 2 comprises a rotatable roller and a cleaning cloth or brush arranged on the outer periphery of the roller, and the baffle 3 is an arc-shaped plate arranged around the roller. The roller is rotatably arranged on a support frame 5, which can form a cavity partially accommodating the roller, and the part of the roller exposed from the support frame 5 can be used to clean the surface. When the cleaning robot is placed on the surface to be cleaned, the rotation axis of the roller can be parallel to the surface to be cleaned, and when the baffle 3 is in the exposed position, the cleaning cloth or brush in a certain arc range of the lower part of the roller can contact the surface to be cleaned, and this certain arc range is the cleaning part of the cleaning element 2, which is constantly changing relative to the constantly rotating roller, and the position of this certain part is fixed relative to the support frame 5. The baffle 3 is an arc-shaped plate matching the shape of the roller, and when the baffle 3 moves to the shielding position, it can cover the cleaning cloth or brush on the roller in the certain arc range, i.e. cover the arc-shaped cleaning part. Of course, in other embodiments, a flat plate or other shaped baffle 3 can be arranged to cooperate with the roller type cleaning element 2.

[0053] In some embodiments, the support frame 5 is provided with a turnover support 4 at the axial first end of the baffle 3, which supports and drives the baffle 3 to rotate around the roller. The baffle 3 is supported by the turnover support 4, and the turnover support 4 can drive the baffle 3 to rotate together around the roller between the exposed position and the shielding position. The turnover support 4 can be a plate-shaped structure at the axial end of the roller, which can be connected to and support the baffle 3.

[0054] In some embodiments, in the shielding position, the baffle 3 is detachable relative to the support frame 5. It can be understood that in some cases, the robot is small in size and the internal structure is relatively compact, and most of the structure of the cleaning element 2 is located inside the main shell, only the cleaning part can be extended out of the main shell to contact the passing surface; accordingly, when the baffle 3 moves to the exposed position, most of the structure of the baffle 3 is located inside the main shell, and when the baffle 3 moves to the shielding position, more structure of the baffle 3 is exposed outside the main shell. Therefore, the baffle 3 is arranged to be detachable and mountable in the shielding position, and after the baffle 3 is detached, the cleaning element 2 can be detached, replaced, repaired, cleaned, and then the baffle 3 can be mounted in place. In addition, when the baffle 3 is detached, in addition to rotating the baffle 3 to the shielding position, the cleaning assembly 1 can also be lowered, so that more structure of the baffle 3 extends out of the main shell, to facilitate the disassembly operation.

[0055] In some embodiments, the turnover support 4 is provided with a disassembly button 10, the turnover support 4 is provided with a first arc-shaped slot 6 extending around the roller, the support frame 5 is provided with a second arc-shaped slot 13 extending around the roller, the axial first end of the baffle 3 is accommodated in the first arc-shaped slot 6, the axial second end of the baffle 3 is accommodated in the second arc-shaped slot 13, and the disassembly button 10 can be moved relative to the turnover support 4 between a locked position and an unlocked position. In the locked position, the disassembly button 10 restricts the rotation of the baffle 3 relative to the turnover support 4, and in the unlocked position, the disassembly button 10 allows the baffle 3 to rotate relative to the turnover support 4, thereby achieving the disassembly and installation of the baffle 3.

[0056] The axial second end of the baffle 3 can rotate in the second arc-shaped slot 13, i.e. between the exposed position and the shielding position, and the second arc-shaped slot 13 supports and guides the baffle 3. The axial first end of the baffle 3 is accommodated in the first arc-shaped slot 6, and when the disassembly button 10 is in the locked position, the rotation of the baffle 3 in the first arc-shaped slot 6 relative to the turnover support 4 can be restricted. Therefore, the first arc-shaped slot 6 and the second arc-shaped slot 13 can restrict the axial movement and radial movement of the baffle 3, and in combination with the restriction of the circumferential rotation of the baffle 3 by the disassembly button 10, the baffle 3 can be maintained on the turnover support 4.

[0057] When the baffle 3 is moved to the shielding position, the dismounting button 10 can be moved to the unlocking position to allow the baffle 3 to be further rotated to be detached from the turnover bracket 4 and the support frame 5, thereby achieving dismounting, as shown in Figure 3 When reinstalling, the two ends of the baffle 3 can be aligned with the first arc-shaped slot 6 and the second arc-shaped slot 13, and the baffle 3 can be moved in the direction from the shielding position to the exposing position to reach the shielding position, and then the dismounting button 10 can be moved to the locking position to limit the movement of the baffle 3, thereby achieving installation of the baffle 3.

[0058] In some embodiments, the axial first end of the baffle 3 is provided with a first clamping slot 11, the surface of the dismounting button 10 towards the baffle 3 is provided with a second clamping slot 12 extending around the circumference of the roller, and the dismounting button 10 can be operated to move radially. In the locking position, the second clamping slot 12 is misaligned with the first clamping slot 11 to limit the circumferential rotation of the baffle 3 relative to the turnover bracket 4, and in the unlocking position, the second clamping slot 12 is aligned with the first clamping slot 11 to allow the baffle 3 to rotate circumferentially relative to the turnover bracket 4 through the second clamping slot 12.

[0059] In some embodiments, the axial first end of the baffle 3 is provided with a first clamping slot 11, the surface of the dismounting button 10 towards the baffle 3 is provided with a second clamping slot 12 extending around the circumference of the roller, and the dismounting button 10 can be operated to move radially. In the locking position, the second clamping slot 12 is misaligned with the first clamping slot 11 to limit the circumferential rotation of the baffle 3 relative to the turnover bracket 4, and in the unlocking position, the second clamping slot 12 is aligned with the first clamping slot 11 to allow the baffle 3 to rotate circumferentially relative to the turnover bracket 4 through the second clamping slot 12. Figure 4 Figure 5 In some embodiments, the axial first end of the baffle 3 is provided with a first clamping slot 11, the surface of the dismounting button 10 towards the baffle 3 is provided with a second clamping slot 12 extending around the circumference of the roller, and the dismounting button 10 can be operated to move radially. In the locking position, the second clamping slot 12 is misaligned with the first clamping slot 11 to limit the circumferential rotation of the baffle 3 relative to the turnover bracket 4, and in the unlocking position, the second clamping slot 12 is aligned with the first clamping slot 11 to allow the baffle 3 to rotate circumferentially relative to the turnover bracket 4 through the second clamping slot 12. Figure 4 In some embodiments, the axial first end of the baffle 3 is provided with a first clamping slot 11, the surface of the dismounting button 10 towards the baffle 3 is provided with a second clamping slot 12 extending around the circumference of the roller, and the dismounting button 10 can be operated to move radially. In the locking position, the second clamping slot 12 is misaligned with the first clamping slot 11 to limit the circumferential rotation of the baffle 3 relative to the turnover bracket 4, and in the unlocking position, the second clamping slot 12 is aligned with the first clamping slot 11 to allow the baffle 3 to rotate circumferentially relative to the turnover bracket 4 through the second clamping slot 12. Figure 5 In some embodiments, the axial first end of the baffle 3 is provided with a first clamping slot 11, the surface of the dismounting button 10 towards the baffle 3 is provided with a second clamping slot 12 extending around the circumference of the roller, and the dismounting button 10 can be operated to move radially. In the locking position, the second clamping slot 12 is misaligned with the first clamping slot 11 to limit the circumferential rotation of the baffle 3 relative to the turnover bracket 4, and in the unlocking position, the second clamping slot 12 is aligned with the first clamping slot 11 to allow the baffle 3 to rotate circumferentially relative to the turnover bracket 4 through the second clamping slot 12.

[0060] ​It can be seen that the locking and unlocking of the baffle 3 and the dismounting and mounting of the baffle 3 can be realized by moving the dismounting button 10 radially, which is simple and easy to operate.

[0061] In other embodiments, the baffle 3 can also be detachably arranged on the turnover bracket 4 and the support frame 5 in other ways, for example, the baffle 3 can be fixed on the turnover bracket 4 by screws or pins, and the baffle 3 can be dismounted by dismounting the screws or pins.

[0062] In addition, the cleaning assembly 1 of the cleaning robot comprises a driving member 7 and a transmission member 8 arranged on the support frame 5, the driving member 7 can drive the turnover bracket 4 to rotate around the center axis of the roller through the transmission member 8, so as to drive the baffle 3 to rotate between the exposed position and the shielding position. The driving member 7 can be a torque output member such as a motor or an engine, or a telescopic driving member such as a pneumatic cylinder, an oil cylinder or an electric cylinder. When the driving member 7 is a torque output member, the transmission assembly can comprise at least one transmission gear or transmission belt, transmission chain or the like which transmits the driving member 7 and the turnover bracket 4, and when the driving member 7 is a telescopic driving member, the transmission member can comprise at least one connecting rod which transmits the driving member 7 and the turnover bracket 4. Under the action of the driving member 7 and the transmission member 8, the turnover bracket 4 and the baffle 3 can be driven to rotate together, so that the baffle 3 rotates between the exposed position and the shielding position. In particular, the power of the cleaning robot is mostly electric power, so that the motor driving mode can be adopted, and the transmission assembly can comprise a plurality of transmission gears which are engaged in sequence, so as to transmit the torque to the turnover bracket 4, and at the same time, the specific transmission ratio of the transmission gears realizes the acceleration or deceleration function of the rotating speed.

[0063] In some embodiments, the turnover bracket 4 and the roller can be driven by the same driving device or different driving devices.

[0064] In addition, in some embodiments, the cleaning member 2 comprises a rotatable disc and a cleaning cloth or a brush arranged on the disc, and the baffle 3 is a flat plate. The movement of the baffle 3 between the exposed position and the shielding position can be translation or rotation.

[0065] In addition, in some embodiments, the cleaning member 2 comprises a track structure and a cleaning cloth or a brush arranged on the track structure, and the baffle 3 is a flat plate or an arc-shaped plate. The movement of the baffle 3 between the exposed position and the shielding position can be translation or rotation.

[0066] In the above embodiments, the cleaning cloth can be soaked with water, and the passing surface can be cleaned in a manner similar to mopping. The brush can be in a dry state, and the passing surface can be cleaned in a manner similar to sweeping.

[0067] In some embodiments, the cleaning member 2 is a wet mop type. That is, the cleaning member 2 can include a mop that can be soaked in water and can perform cleaning on the passing surface similar to mopping.

The lifting assembly 9 can include a base and a driving assembly, the driving assembly can drive the cleaning assembly 1 to move up and down relative to the base, and the driving assembly can be a combination of a motor and a screw mechanism, or an oil cylinder, a gas cylinder, etc.

[0069] In another aspect, the present application provides a cleaning method of a cleaning robot, which includes the cleaning assembly 1, the cleaning assembly 1 includes the cleaning member 2 and the baffle 3, and the cleaning method includes the following steps: judging whether the passing surface of the cleaning robot needs to be cleaned; if the passing surface does not need to be cleaned, the cleaning robot keeps or starts a non-cleaning state, in the non-cleaning state, the cleaning member 2 stops cleaning action, and the baffle 3 is located at a shielding position to shield the cleaning part of the cleaning member 2, so that the cleaning part of the cleaning member 2 is isolated from the passing surface; if the passing surface needs to be cleaned, the cleaning robot keeps or starts a cleaning state, in the cleaning state, the baffle 3 is located at an exposed position to expose the cleaning part of the cleaning member 2, so that the cleaning part of the cleaning member 2 is in contact with the passing surface, and the cleaning member 2 starts cleaning action to clean the passing surface.

[0070] The cleaning robot can be provided with an ultrasonic sensor to detect whether the passing surface is a passing surface that needs to be cleaned or a passing surface that does not need to be cleaned, of course, a camera can also be used to collect images to determine whether the passing surface needs to be cleaned.

[0071] When the cleaning robot moves, the following situations can occur: always on the way surface that does not need to be cleaned, it will remain in a non-cleaning state, wherein the cleaning member 2 remains to stop cleaning action, the baffle 3 remains in the shielding position; always on the way surface that needs to be cleaned, it will remain in a cleaning state, wherein the cleaning member 2 remains to start cleaning action; moving from the way surface that does not need to be cleaned to the way surface that needs to be cleaned, its state will change from the non-cleaning state to the cleaning state, i.e. starting cleaning state, the baffle 3 moves from the shielding position to the exposed position, the cleaning member 2 starts cleaning action; moving from the way surface that needs to be cleaned to the way surface that does not need to be cleaned, its state will change from the cleaning state to the non-cleaning state, i.e. starting non-cleaning state, the cleaning member 2 stops cleaning action, the baffle 3 moves from the exposed position to the shielding position. Among them, the cleaning action refers to that the cleaning member 2 is in the running state, and the roller, disc or track structure thereof is in the rotating state.

[0072] In addition, in some embodiments, the cleaning robot is in a non-cleaning state, and the cleaning assembly 1 is raised to a first position to be away from the way surface; the cleaning robot is in a cleaning state, and the cleaning assembly 1 is lowered to a second position to contact the way surface. The cleaning robot is in a non-cleaning state, and the cleaning assembly 1 is kept in the first position away from the way surface, and the cleaning robot is in a cleaning state, and the cleaning assembly 1 is kept in the second position in contact with the way surface; when the cleaning robot is converted from the non-cleaning state to the cleaning state, the cleaning assembly 1 is lowered from the first position to the second position; when the cleaning robot is converted from the cleaning state to the non-cleaning state, the cleaning assembly 1 is raised from the second position to the first position. Among them, the first position can be the highest position, and the second position can be the lowest position.

[0073] Further, in some embodiments, when the cleaning robot moves from the passing surface requiring cleaning to the passing surface not requiring cleaning, the cleaning action of the cleaning member 2 is stopped, then the cleaning assembly 1 is driven to rise to the first position and the baffle 3 is driven to move to the shielding position; when the cleaning robot moves from the passing surface not requiring cleaning to the passing surface requiring cleaning, the cleaning assembly 1 is driven to descend and the baffle 3 is driven to move to the exposing position, then the cleaning action of the cleaning member 2 is started. That is, when the cleaning robot moves from the passing surface requiring cleaning to the passing surface not requiring cleaning, the cleaning robot needs to be converted from the cleaning state to the non-cleaning state, i.e. to stop the running of the cleaning member 2 and to drive the cleaning assembly 1 and the baffle 3 to move to the respective corresponding positions; when the cleaning robot moves from the passing surface not requiring cleaning to the passing surface requiring cleaning, the cleaning robot needs to be converted from the non-cleaning state to the cleaning state, i.e. to drive the cleaning assembly 1 and the baffle 3 to move to the respective corresponding positions and to start the running of the cleaning member 2. It can be seen that the state conversion of the cleaning robot needs the corresponding changes of the three aspects of the baffle 3, the cleaning member 2 and the cleaning assembly 1.

[0074] In addition, in some embodiments, the cleaning robot is initially set to the non-cleaning state; when the initially set cleaning robot moves to the passing surface requiring cleaning, the cleaning assembly 1 is driven to descend and the baffle 3 is driven to move to the exposing position, then the cleaning action of the cleaning member 2 is started; when the initially set cleaning robot moves to the passing surface not requiring cleaning, the positions of the cleaning assembly 1 and the baffle 3 are kept unchanged. The cleaning robot is initially set to the non-cleaning state, when the initially set cleaning robot moves to the passing surface requiring cleaning, the cleaning robot can be converted from the non-cleaning state to the cleaning state, and when the initially set cleaning robot moves to the passing surface not requiring cleaning, the cleaning robot can keep the original non-cleaning state.

[0075] In some embodiments, the movement of the baffle 3 and the rising or descending of the cleaning assembly 1 are started simultaneously,

[0076] In some embodiments, the movement of the baffle 3 and the rising or descending of the cleaning assembly 1 are started simultaneously,

[0077] In some embodiments, the movement of the baffle 3 and the rising or descending of the cleaning assembly 1 are started simultaneously,

[0078] That is, when the cleaning robot is switched from the cleaning state to the non-cleaning state, the lifting movement of the cleaning assembly 1 from the second position to the first position and the movement of the baffle 3 from the exposed position to the shielding position are started at the same time, in some cases, the cleaning assembly 1 reaches the first position at the same time as the baffle 3 reaches the shielding position, in other cases, the cleaning assembly 1 reaches the first position after a period of time after the baffle 3 reaches the shielding position, in yet other cases, the cleaning assembly 1 reaches the first position after a period of time after the baffle 3 reaches the shielding position; similarly, when the cleaning robot is switched from the non-cleaning state to the cleaning state, the lowering movement of the cleaning assembly 1 from the first position to the second position and the movement of the baffle 3 from the shielding position to the exposed position are also started at the same time, in some cases, the cleaning assembly 1 reaches the second position at the same time as the baffle 3 reaches the exposed position, in other cases, the cleaning assembly 1 reaches the second position after a period of time after the baffle 3 reaches the exposed position, in yet other cases, the cleaning assembly 1 reaches the second position after a period of time after the baffle 3 reaches the exposed position.

[0079] In other embodiments, the movement of the baffle 3 and the lifting or lowering of the cleaning assembly 1 do not start at the same time,

[0080] wherein, when the cleaning assembly 1 is driven to move from the first position to the second position by a first predetermined distance or for a first predetermined time, or when the cleaning assembly 1 is driven to move from the first position to the second position and then the baffle 3 is driven to move from the shielding position to the exposed position;

[0081] wherein, when the cleaning assembly 1 is driven to move from the second position to the first position by a second predetermined distance or for a second predetermined time, or when the cleaning assembly 1 is driven to move from the second position to the first position and then the baffle 3 is driven to move from the exposed position to the shielding position.

[0082] wherein the first predetermined distance and the second predetermined distance are greater than 0 and less than the distance between the first position and the second position, the first predetermined time is greater than 0 and less than the movement time of the cleaning assembly 1 from the second position to the first position, and the second predetermined time is greater than 0 and less than the movement time of the cleaning assembly from the first position to the second position.

[0083] That is, when the cleaning robot is switched from the cleaning state to the non-cleaning state, the baffle 3 starts to move from the exposed position to the shielding position after the cleaning assembly 1 is raised from the second position for a distance or for a period of time, wherein in some cases, the baffle 3 reaches the shielding position at the same time as the cleaning assembly 1 reaches the first position, in other cases, the baffle 3 reaches the shielding position after the cleaning assembly 1 reaches the first position for a period of time, and in yet other cases, the cleaning assembly 1 reaches the first position after the baffle 3 reaches the shielding position for a period of time; or the baffle 3 starts to move from the exposed position to the shielding position after the cleaning assembly 1 moves from the second position to the first position. It can be understood that moving the cleaning assembly 1 to the first position first can form a space for accommodating the baffle 3 between the cleaning assembly 1 and the passing surface, so that the baffle 3 does not collide with the passing surface when it moves to the shielding position. Similarly, when the cleaning robot is switched from the non-cleaning state to the cleaning state, the baffle 3 starts to move from the shielding position to the exposed position after the cleaning assembly 1 is lowered from the first position for a distance or for a period of time, wherein in some cases, the baffle 3 reaches the exposed position at the same time as the cleaning assembly 1 reaches the second position, in other cases, the baffle 3 reaches the exposed position after the cleaning assembly 1 reaches the second position for a period of time, and in yet other cases, the cleaning assembly 1 reaches the second position after the baffle 3 reaches the exposed position for a period of time; or the baffle 3 starts to move from the shielding position to the exposed position after the cleaning assembly 1 moves from the first position to the second position.

[0084] In addition, in other embodiments, the cleaning robot can also move the baffle 3 first and then move the cleaning assembly 1 when switching between the cleaning state and the non-cleaning state. When the cleaning robot is switched from the cleaning state to the non-cleaning state, the cleaning assembly 1 starts to move from the second position to the first position after the baffle 3 is moved from the exposed position to the shielding position for a period of time, wherein in some cases, the baffle 3 reaches the shielding position at the same time as the cleaning assembly 1 reaches the first position, in other cases, the baffle 3 reaches the shielding position after the cleaning assembly 1 reaches the first position for a period of time, and in yet other cases, the cleaning assembly 1 reaches the first position after the baffle 3 reaches the shielding position for a period of time; or the cleaning assembly 1 starts to move from the second position to the first position after the baffle 3 reaches the shielding position. When the cleaning robot is switched from the non-cleaning state to the cleaning state, the cleaning assembly 1 starts to move from the first position to the second position after the baffle 3 is moved from the shielding position to the exposed position for a period of time, wherein in some cases, the baffle 3 reaches the exposed position at the same time as the cleaning assembly 1 reaches the second position, in other cases, the baffle 3 reaches the exposed position after the cleaning assembly 1 reaches the second position for a period of time, and in yet other cases, the cleaning assembly 1 reaches the second position after the baffle 3 reaches the exposed position for a period of time; or the cleaning assembly 1 starts to move from the first position to the second position after the baffle 3 reaches the exposed position.

[0085] The moving time of the cleaning assembly 1 between the first position and the second position can be set according to actual needs, for example, can be 2-5 seconds, and the distance between the first position and the second position can be 2-4 cm. In the case of asynchronous movement of the baffle 3 and the cleaning assembly 1, the baffle 3 can be moved after the cleaning assembly 1 is moved for 1-3 seconds, or the baffle 3 can be moved after the cleaning assembly 1 is moved for 1-2 cm.

[0086] As described above, when the cleaning assembly 1 and the baffle 3 move asynchronously, the cleaning assembly 1 moves first, because the cleaning element 2 in the cleaning assembly 1 is the core structure, and has higher priority in rising and falling, and the baffle 3 is an auxiliary component, and has relatively lower priority. Of course, in other embodiments, the baffle 3 can be moved first, and then the cleaning assembly 1 is raised and lowered, for example, the baffle 3 is moved for a distance (less than the total distance required to be moved), a time (less than the total time required to be moved), or the baffle 3 is moved to the position (to the target position, such as the exposure position or the shielding position), and then the cleaning assembly 1 is moved.

[0087] In the cleaning method of the cleaning robot described above, the cleaning robot adopts the cleaning assembly 1 described in the above solution or the cleaning mechanism described in the above solution.

[0088] In addition, the present solution also provides a cleaning robot, which comprises the cleaning assembly 1 described in the above solution or the cleaning mechanism described in the above solution. The cleaning robot can comprise a main shell, and the cleaning assembly 1 or the cleaning mechanism can be arranged in the main shell and partially protrude from the bottom.
