Description

[0001] This application claims the priority of a Chinese patent application with the application number 2024229809193 and the utility model name "Cleaning Equipment" filed on December 03, 2024, the entire content of which is incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning technology, and in particular, to a cleaning equipment. Background Art

[0003] With the development of science and technology, the sweeping robot has also been updated. In order to enable the sweeping robot to clean complex terrains such as the corners of a wall (inner right-angle corner, outer right-angle corner, and obtuse-angle corner), the edge of a wall, and narrow areas, the original edge-sweeping or mopping cloth structure on the sweeping robot is set to be expandable (i.e., extend beyond the outer edge of the sweeping robot). Although this can improve the cleaning effect and cleaning range of the sweeping robot, since the rotation center of the existing mopping cloth generally does not protrude beyond the outer edge of the sweeping robot when it expands, the cleaning range of the sweeping robot is limited, and it cannot clean narrow corners (i.e., corners with an acute angle) and even narrower areas (such as the narrow area between the bottom of a locker and the ground). Summary of the Invention

[0004] The main objective of this application is to provide a cleaning equipment to solve the problem of limited cleaning range of the cleaning equipment in the prior art.

[0005] According to one aspect of this application, a cleaning equipment is provided, including:

[0006] A main body;

[0007] A first cleaning mechanism, the first cleaning mechanism includes a first power component and a first cleaning component, the first power component is connected to the first cleaning component to drive the first cleaning component to rotate along a first direction or a second direction opposite to the first direction, the first cleaning component has a retracted position close to the main body and an extended position beyond the outer edge of the main body, and within the projection in the height direction of the main body, the area of the first cleaning component beyond the outer edge of the main body when the first cleaning component is in the extended position is greater than the area of the first cleaning component beyond the outer edge of the main body when the first cleaning component is in the retracted position;

[0008] When the first cleaning component is in the extended position, within the projection in the height direction of the main body, the rotation center of the first cleaning component is located outside the main body.

[0009] Further, an avoidance notch is provided on the main body. The avoidance notch extends from the inner side of the main body towards the edge of the main body, and an opening is provided at one end of the avoidance notch close to the edge of the main body. The first cleaning mechanism moves along the avoidance notch to move between the outer expansion position and the inner retraction position. The opening is at least used to avoid the first cleaning mechanism to allow the rotation center of the first cleaning component to be located outside the main body when the first cleaning component is in the outer expansion position.

[0010] Further, a rotating part is provided on the main body. The first cleaning mechanism is rotatably connected to the main body through the rotating part. The first cleaning component moves around the rotating part to switch between the inner retraction position and the outer expansion position, and the maximum outer expansion angle of the first cleaning component is less than 180°;

[0011] In the projection in the height direction of the main body: when the first cleaning component is in the inner retraction position, the connection line between the rotation center of the first cleaning component and the rotating part is J1. When the first cleaning component expands to the limit position, the connection line between the rotation center of the first cleaning component and the rotating part is J2. The maximum outer expansion angle is the included angle between J1 and J2.

[0012] Further, a rotating part is provided on the main body. The first cleaning mechanism is rotatably connected to the main body through the rotating part. The first power component includes a first driving part and a first transmission component;

[0013] The first driving part is rotatably mounted on the main body through the rotating part. The first driving part has a rotating shaft, and the rotating shaft is coaxially arranged with the rotating part, or the rotating shaft is misaligned with the rotating part and the first driving part can move around the rotating part;

[0014] The first transmission component is connected between the first driving part and the first cleaning component. The rotation of the rotating shaft drives the first transmission component to drive the first cleaning component to rotate along the first direction or the second direction.

[0015] Further, an avoidance notch is provided on the main body. In the projection in the height direction of the main body: when the maximum width of the outer contour of the first transmission component is less than or equal to the maximum outer expansion radius from the rotating part to the avoidance notch, the maximum width of the outer contour of the first transmission component is arranged along the direction parallel to the maximum outer expansion radius or intersects with the maximum outer expansion radius.

[0016] Further, an avoidance notch is provided on the host. When the maximum width of the outer contour of the first transmission assembly is greater than the maximum outward expansion radius from the rotating part to the avoidance notch, the maximum width of the outer contour of the first transmission assembly intersects with the maximum outward expansion radius.

[0017] Further, the cleaning device further includes a cover plate assembly. The cover plate assembly is disposed on the host, and the cover plate assembly has an open state in which the opening is opened when the first cleaning component is converted from the retracted position to the outward expansion position, and the cover plate assembly also has a covering state in which the opening is covered when the first cleaning component is in the retracted position.

[0018] Further, the cleaning device further includes a limiting component. The limiting component has a first state in which it avoids the first cleaning component to allow the first cleaning component to be converted between the retracted position and the outward expansion position, and the limiting component also has a second state in which it stops the first cleaning component to prevent the first cleaning component from being converted from the retracted position to the outward expansion position.

[0019] Further, the cleaning device further includes a second cleaning mechanism. The second cleaning mechanism includes a second power component and a second cleaning component. The second power component is disposed on the host and is connected to the second cleaning component to drive the second cleaning component to rotate along the first direction or the second direction;

[0020] The cleaning device is configured such that: when the first cleaning component is in the retracted position, the rotation direction of the first cleaning component is opposite to that of the second cleaning component; when the first cleaning component is in the outward expansion position, the rotation direction of the first cleaning component is the same as or opposite to that of the second cleaning component.

[0021] Further, the cleaning device further includes an auxiliary component. The auxiliary component is disposed on the host, and an avoidance surface is provided on the auxiliary component. The avoidance surface is at least used to reserve space for the first cleaning component or the second cleaning component to swing between the retracted position and the outward expansion position. The auxiliary component includes at least one of a radar, a water tank, a universal wheel assembly, a dust collection box, an air pump, a first conveying channel, a second conveying channel, and a mobile wheel group.

[0022] In the present application, when the cleaning device performs edge cleaning (i.e., the cleaning device closely adheres to the edges of obstacles such as walls and furniture for cleaning), in order to ensure the cleaning effect and cleaning range of the cleaning device, the first cleaning component needs to be converted to the extended position for edge cleaning. However, when the extended first cleaning component is cleaning a corner (inner right-angle corner or outer right-angle corner), in order to make the first cleaning component closely adhere to the corner, the main body needs to rotate accordingly following the shape of the corner to adjust the posture of the main body itself. During this process, if the rotation center of the first cleaning component is located inside the main body in the projection direction of the main body, it may cause the first cleaning component not to extend out of the outer edge of the main body as much as possible, resulting in poor edge cleaning effect of the first cleaning component (since the main body may collide with obstacles such as walls, thereby changing the posture of the first cleaning component) and reduced cleaning range. Therefore, in the present application, when the first cleaning component extends to a certain moment in the extended position, in the projection direction of the main body, the rotation center of the first cleaning component is located outside the main body, which can prevent the main body from interfering with the wall surface during edge cleaning and causing the first cleaning component not to closely adhere to the wall edge or corner for movement, and can, to a certain extent, expand the cleaning range of the first cleaning component, thereby greatly improving the cleaning efficiency and cleaning range of the cleaning device.

Detailed implementation manners

[0049] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0050] It should be noted that the terms used herein are only for describing the specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0051] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0052] As described in the background art, although existing floor-sweeping robots can clean complex terrains such as corners (inner right-angle corners, outer right-angle corners, and obtuse-angle corners), wallsides, and narrow areas, since the rotation center of the existing mopping cloth generally does not protrude beyond the outer edge of the floor-sweeping robot when it expands, the cleaning range of the floor-sweeping robot is limited, and it cannot clean narrow corners (i.e., corners with an acute angle) and even narrower areas (such as the narrow area between the bottom of a locker and the ground). For this reason, the present application provides a new cleaning device. When the mopping cloth of the application device expands, its rotation center can protrude beyond the outer edge of the floor-sweeping robot, so that the cleaning range of the cleaning device is expanded. The cleaning device of the present application will be introduced below with reference to the drawings.

[0053] See Figures 1 to 22As shown, an embodiment of the present application provides a cleaning device 100, which includes but is not limited to a floor sweeping robot (including a robot with one or more cleaning mechanisms), a mopping machine (a robot with mopping function but without floor sweeping function), a sweeping and mopping integrated machine, a floor washing machine (such as a handheld floor washing machine, a non-handheld floor washing machine), or a base station of the above floor sweeping robot, mopping machine, sweeping and mopping integrated machine, and floor washing machine. The cleaning device 100 includes a main body 10 and a first cleaning mechanism 20.

[0054] Among them, the first cleaning mechanism 20 includes a first power component 21, a first cleaning component 22, and a first stop component 23. The first power component 21 is connected to the first cleaning component 22 to drive the first cleaning component 22 to rotate along a first direction or a second direction opposite to the first direction. The first cleaning component 22 has a retracted position (such as Figure 1 , Figure 2 , Figure 6 and Figure 7 shown) close to the main body 10 and an extended position (such as Figure 3 , Figure 8 shown) beyond the outer edge of the main body 10. And within the projection in the height direction of the main body 10, the area where the first cleaning component 22 extends beyond the outer edge of the main body 10 when the first cleaning component 22 is in the extended position is greater than the area where the first cleaning component 22 extends beyond the outer edge of the main body 10 when the first cleaning component 22 is in the retracted position. It can be understood that when the first cleaning component 22 is in the retracted position, the first cleaning component 22 may partially extend beyond the outer edge of the main body 10, or may be entirely located inside the main body 10 and not protrude beyond the outer edge of the main body 10 at all; when the first cleaning component 22 is in the extended position, the area where the first cleaning component 22 protrudes beyond the outer edge of the main body 10 is greater than the area where the first cleaning component 22 protrudes beyond the outer edge of the main body 10 when the first cleaning component 22 is in the retracted position. In some embodiments of the present application, when the first cleaning component 22 is in the extended position, it is preferably arranged such that the first cleaning component 22 protrudes beyond the outermost edge of the main body 10 in a predetermined direction (a direction perpendicular to the moving direction of the main body 10). In this way, when the main body 10 moves, it is more suitable to drive the first cleaning component 22 to clean the edges of obstacles such as walls and furniture.

[0055] When the cleaning device 100 in this application is working, the cleaning device 100 is configured such that when the first cleaning component 22 rotates in the first direction and is subjected to a moment in the second direction, the first cleaning mechanism 20 swings relative to the main body 10 in the second direction to drive the first cleaning component 22 to be in an extended position. Specifically, when the first power component 21 drives the first cleaning component 22 to rotate in the first direction, when the first cleaning component 22 contacts a cleaning surface such as the ground or a tabletop, a moment will be generated. This moment can cause the entire first cleaning mechanism 20 to swing relative to the main body 10 in the second direction opposite to the first direction, driving the first cleaning component 22 to protrude beyond the outer edge of the main body 10 and be in an extended position. At this time, the first cleaning component 22 can avoid mutual interference between the main body 10 and obstacles such as furniture or walls, and contact the edges of the walls or furniture for edge cleaning.

[0056] The cleaning device is also configured such that when the first cleaning component 22 rotates in the second direction and is subjected to a moment in the first direction, the first cleaning mechanism 20 swings relative to the main body 10 in the first direction to drive the first cleaning component 22 to be in a retracted position. Specifically, when the first power component 21 drives the first cleaning component 22 to rotate in the second direction, when the first cleaning component 22 contacts a cleaning surface such as the ground or a tabletop, a moment will be generated. This moment can cause the entire first cleaning mechanism 20 to swing relative to the main body 10 in the first direction opposite to the second direction, driving the first cleaning component 22 to retract to the inside close to the main body 10 and be in a retracted position. At this time, it is convenient to store and place the cleaning device 100.

[0057] It can be understood that the first direction in this application can be the clockwise direction or the counterclockwise direction. When the first direction is the clockwise direction, the second direction is the counterclockwise direction; when the first direction is the counterclockwise direction, the second direction is the clockwise direction. In addition, the moment in this application can be the frictional moment applied by the ground or the tabletop to the first cleaning component when the first cleaning component 22 rubs against the ground or the tabletop, etc., or the moment generated by the reaction force of other objects on the first cleaning component when the centrifugal force of the self-rotation of the first cleaning component 22 acts on other objects, or the moment applied by other friction mechanisms to the first cleaning component when the first cleaning component 22 contacts other friction mechanisms, etc.

[0058] Exemplarily, the retracted position includes multiple retracted position points. When the first cleaning component 22 is retracted to the innermost position of the main body 10, the first cleaning component 22 is at the limit position of the retracted position. The expanded position includes multiple expanded position points. When the first cleaning component 22 is expanded to the outermost position of the main body 10, the first cleaning component 22 is at the limit position of the expanded position. The positions of the first cleaning component 22 within a first predetermined distance range of moving from the limit position of the retracted position to the limit position of the expanded position all belong to the retracted position. The positions of the first cleaning component 22 within a second predetermined distance range of moving from the limit position of the expanded position to the limit position of the retracted position all belong to the expanded position. The specific sizes of the first predetermined distance and the second predetermined distance can be adjusted accordingly according to needs and actual situations. The present application does not limit the specific sizes of the first predetermined distance and the second predetermined distance. Any implementation manner of adjusting the first predetermined distance and the second predetermined distance under the concept of the present application is within the scope protected by the present application. Refer to Figure 11 As shown, R1 is the first tangent line R1 that is tangent to the edge of the main body 10 along a predetermined direction of the main body 10. When the first cleaning component 22 moves along the direction from N1 to N2, if the first cleaning component 22 is in a position that does not exceed the first tangent line R1 (that is, the first cleaning component 22 is in a position that does not exceed Figure 11 the position of the mop bracket 221 shown by the solid line in Figure 11 ), then the first cleaning component 22 is in the retracted position; if the first cleaning component 22 is in a position that exceeds the first tangent line R1 (that is, the first cleaning component 22 is in a position that exceeds Figure 11 the position of the mop bracket 221 shown by the solid line in

[0059] ), for example, Figure 3 the position of the mop bracket 221 shown by the dashed line in Figure 8 ), then the first cleaning component 22 is in the expanded position. Figure 11 Furthermore, as shown in

[0060] and Figure 11 Figure 11 shown, when the first cleaning component 22 is in the expanded position, within the projection in the height direction of the main body 10, the rotation center of the first cleaning component 22 is located outside the main body 10. It can be understood that when the first cleaning component 22 moves between the expanded position and the retracted position in this embodiment, within the projection in the height direction of the main body 10, the rotation center of the first cleaning component 22 can be located outside the main body 10 or inside the main body 10. In the present application, it is preferably requested to protect the case where the first cleaning component 22 is located outside the main body 10 at least at one moment when it is expanded.

[0060] Specifically, the rotation center of the first cleaning component 22 is Figure 11The center O of the middle mop bracket. When the cleaning device performs edge cleaning (that is, the cleaning device closely adheres to the edges of obstacles such as walls and furniture for cleaning), in order to ensure the cleaning effect and cleaning range of the cleaning device, the first cleaning component 22 needs to be converted to the outward expansion position for edge cleaning. However, when the outward-expanded first cleaning component 22 cleans a corner (an inner right-angle corner or an outer right-angle corner), in order to make the first cleaning component 22 closely adhere to the corner, the main body 10 needs to rotate accordingly following the shape of the corner to adjust the attitude of the main body 10 itself. During this process, if within the projection direction of the main body 10, the rotation center of the first cleaning component 22 is located inside the main body 10, it may cause the first cleaning component 22 not to expand out of the outer edge of the main body 10 as much as possible, resulting in poor edge cleaning effect of the first cleaning component 22 (since the main body 10 may bump into obstacles such as walls, thereby changing the attitude of the first cleaning component 22) and reduced cleaning range. Therefore, in this application, when the first cleaning component 22 expands to a certain moment at the outward expansion position, within the projection direction of the main body 10, the rotation center of the first cleaning component 22 is located outside the main body 10, which can prevent the main body 10 from interfering with the wall surface during edge cleaning, causing the first cleaning component 22 not to closely adhere to the wall edge or corner for movement, and can expand the cleaning range of the first cleaning component 22 to a certain extent, thereby greatly improving the cleaning efficiency and cleaning range of the cleaning device.

[0061] Furthermore, the first stop component 23 is arranged on the first power component 21, and the first stop component 23 is configured to contact an obstacle when the first cleaning component 22 is in the outward expansion position to prevent the first cleaning component 22 from making hard contact with the obstacle. It can be understood that the prevention of the first cleaning component 22 from making hard contact with the obstacle here means: the situation where there is no hard object in the first cleaning component 22 or other structures with hard supports inside directly contact the obstacle.

[0062] The first stop component 23 is driven by the reaction force exerted by the obstacle to swing the first cleaning mechanism 20 (specifically, swing relative to the main body 10), so as to drive the first cleaning component 22 to move in the direction close to the inward retraction position. It can be understood that the obstacles described in this application include but are not limited to indoor walls, coffee tables, chairs, beds, refrigerators and other furniture, as well as other objects placed in the space, etc.

[0063] In this application, by setting the first stop component 23, when the first cleaning component 22 expands outward to protrude beyond the outermost edge of the main body 10 in a predetermined direction to clean the edges of obstacles such as walls and furniture, if the first cleaning component 22 is relatively close to the obstacle, the first stop component 23 is used to contact the obstacle to prevent the first cleaning component 22 from making hard contact with the obstacle. In this way, the rotating first cleaning component 22 will not scratch the obstacle. At the same time, due to the reaction force exerted by the obstacle on the first stop component 23, the entire first cleaning mechanism 20 can swing, driving the first cleaning component 22 to move towards the inward retracted position to achieve inward retraction. Thereafter, when the force exerted by the obstacle on the first stop component 23 disappears, the first power component 21 continuously drives the first cleaning component 22 to rotate in the first direction. The friction torque generated when the first cleaning component 22 contacts the ground can drive the first cleaning component 22 to switch to the outward expanded position to clean the edge along the obstacle.

[0064] It can be seen that the cleaning device 100 in this application is not only convenient for cleaning the edges along obstacles, but also not easy to scratch the obstacles.

[0065] See Figure 15 and Figure 16 As shown, the first cleaning component 22 rotates in the clockwise direction. Among them, f is the frictional force between the first cleaning component 22 and the ground, F1 is the contact force generated when the obstacle contacts the first cleaning component 22 or the first stop component 23, and F2 is the frictional force exerted by the obstacle on the first stop component 23 or the first cleaning component 22. The torques exerted by the above-mentioned forces on the first cleaning mechanism 20 are respectively M f = f * L3, M F1 = F1 * L2, M F2 = F1 * L1. Among them, it is defined that if the resultant torque of the first cleaning mechanism 20 is greater than 0, the first cleaning mechanism 20 rotates counterclockwise; if the torque is less than 0, the first cleaning mechanism 20 rotates clockwise. The resultant torque received by the first cleaning mechanism 20 is M f + M F1 + M F2 .

[0066] In Figure 15 , by combining the force analysis, it can be judged that: M f + M F1 + M F2 > 0. That is to say, when the first cleaning component 22 contacts the obstacle without setting the first stop component 23, the resultant torque of the first cleaning mechanism 20 is positive, and the first cleaning mechanism 20 rotates counterclockwise, always showing an outward expansion trend, and the first cleaning mechanism 20 cannot be retracted during impact. In Figure 16 , by combining the force analysis, it can be judged that: M f + M F1+M F2 <0, that is to say, when the first stop member 23 is provided in this embodiment, when the first cleaning member 22 contacts an obstacle, the resultant moment of the first cleaning mechanism 20 is negative, and the first cleaning mechanism 20 rotates in the clockwise direction. The moment generated by the contact force between the first stop member 23 and the obstacle on the rotation center of the outward expansion movement of the entire first cleaning mechanism 20 will cause the assembly to retract, so that the entire first cleaning mechanism 20 realizes flexible outward expansion.

[0067] Such as Figures 2 to 5 , Figure 8 and Figure 13 As shown, within the projection of the main body 10 in the height direction, at least a part of the first stop member 23 protrudes beyond the outer edge of the first cleaning member 22 for contacting an obstacle, thereby preventing the first cleaning member 22 from making hard contact with the obstacle. That is to say, in this application, by connecting the first stop member 23 to the first power member 21 and making at least a part of the first stop member 23 protrude beyond the outer edge of the first cleaning member 22 within the projection of the main body 10 in the height direction, it can be ensured that when the first cleaning member 22 expands outward to the outward expansion position, it can contact the obstacle, thereby avoiding hard contact between the first cleaning member 22 and the obstacle, and preventing the first cleaning member 22 from scratching the obstacle when rotating. The structure is simple and easy to implement.

[0068] In some embodiments of this application, the first cleaning member 22 includes, but is not limited to, a mop assembly, a roller assembly, a side sweeping assembly, etc. In this application, the first cleaning member 22 is taken as a mop assembly for introduction. Specifically, the first cleaning member 22 includes a mop bracket 221 and a flexible mop 222. Among them, the mop bracket 221 is connected to the first power member 21 and rotates in the first direction or the second direction under the drive of the first power member 21; the flexible mop 222 is disposed on the bottom surface of the mop bracket 221, and within the projection of the main body 10 in the height direction, the flexible mop 222 protrudes beyond the outer edge of the mop bracket 221, and the first stop member 23 is located inside the flexible mop 222. And, within the projection of the main body 10 in the height direction, at least a part of the first stop member 23 protrudes beyond the outer edge of the mop bracket 221. With such a setting, when the first stop member 23 contacts an obstacle, the flexible mop 222 can also contact the obstacle. At this time, if the mop bracket 221 drives the flexible mop 222 to rotate, the flexible mop 222 can effectively clean the edge of the obstacle. During this process, the first stop member 23 can protect the mop bracket 221 from contacting the obstacle, thereby preventing the mop bracket 221 from being damaged by an external impact. It can be seen that during the cleaning operation of the cleaning device 100 in this application, not only can the edge of the obstacle be cleaned, but also the obstacle will not be scratched. Further, refer to Figures 3 to 5As shown, the first stop member 23 includes a stop plate 231. Within the projection in the height direction of the main machine 10, the stop plate 231 at least partially protrudes beyond the outer edge of the mop bracket 221. In this way, when the first cleaning member 22 expands outwards to the expanded position, the stop plate 231 can come into contact with an obstacle before the rigid mop bracket 221 on the first cleaning member 22, preventing the rigid mop bracket 221 from scratching the obstacle during the process of rotating to perform the cleaning operation. Moreover, since the stop plate 231 comes into contact with the obstacle before the rigid mop bracket 221 on the first cleaning member 22, the stop plate 231 can, to a certain extent, prevent the mop bracket 221 from being damaged by hitting the obstacle.

[0069] For the convenience of processing and assembly, the stop plate 231 in the present application can be arranged on the first transmission assembly 212 of the first power member 21 by means of snap connection, screw connection, welding, magnetic attraction, integral molding, etc., specifically arranged on the outer shell or surface of the first transmission assembly 212, and no specific limitation is made in the present application. Additionally, in other embodiments of the present application, the first stop member 23 can also be a stop block, a stop post, etc. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0070] Furthermore, referring to Figure 3 , Figures 6 to 8 , Figure 10 , Figures 12 to 13 and Figure 22 As shown, the first cleaning member 22 further includes a soft rubber layer 223. The soft rubber layer 223 covers at least a partial area of the outer periphery of the mop bracket 221. Within the projection in the height direction of the main machine 10, the soft rubber layer 223 protrudes beyond the outer edge of the mop bracket 221, and the soft rubber layer 223 is located inside the first stop member 23 to prevent the mop bracket 221 from coming into contact with an obstacle.

[0071] Specifically, the soft rubber layer 223 can cover the entire outer periphery of the mop bracket 221, or can cover a partial area of the outer periphery of the mop bracket 221. This embodiment shows the case where the soft rubber layer 223 covers a partial area of the outer periphery of the mop bracket 221. Specifically, the soft rubber layer 223 covers the outer ring of the mop bracket 221 along the radial direction of the mop bracket 221. Although the stop baffle 231 can play a certain protective role for the mop bracket 221, due to the complexity of the working environment of the cleaning device, some obstacles may collide with the mop bracket 221 from the area not protected by the stop baffle 231, which is likely to damage the mop bracket 221. The setting of the soft rubber layer 223 can play a protective role for the mop bracket 221 to a certain extent. When the mop bracket 221 encounters an obstacle, the soft rubber layer 223 contacts first, which can play a certain buffering role, preventing the mop bracket 221 from directly colliding with the obstacle rigidly and avoiding damaging the mop bracket 221 and the obstacle (when the obstacle is a structure such as a table leg or a wall surface, it is necessary to prevent the structure such as the table leg or the wall surface from being damaged).

[0072] Further, as Figure 13 shown, within the projection in the height direction of the main body 10: the maximum width D of the stop baffle 231 protruding beyond the outer edge of the mop bracket 221 satisfies the relationship: 0 < D ≤ 5 mm. Exemplarily, the value of D can be 1 mm, 2 mm, 3 mm, 4 mm or 5 mm. When the maximum width D of the stop baffle 231 protruding beyond the outer edge of the mop bracket 221 is less than or equal to 0, the stop baffle 231 cannot contact the obstacle prior to the mop bracket 221; when the maximum width D of the stop baffle 231 protruding beyond the outer edge of the mop bracket 221 is greater than 5 mm, the mop bracket 221 cannot support the flexible mop 222 well, which is not convenient for effectively cleaning the edge of the obstacle. It can be seen that in this application, by making the maximum width D of the stop baffle 231 protruding beyond the outer edge of the mop bracket 221 satisfy the relationship 0 < D ≤ 5 mm, not only can the hard mop bracket 221 be prevented from scratching the obstacle, but also it is convenient to support the flexible mop 222, so as to effectively clean the edge of the obstacle.

[0073] Optionally, the maximum width L of the flexible mop 222 in the present application protruding from the outer edge of the stop plate 231 satisfies the relationship 0 ≤ L ≤ 5 mm. Exemplarily, the value of L can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm, etc. When the large width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 is less than 0, the flexible mop 222 cannot contact the obstacle, which is not convenient for cleaning the edge of the obstacle; when the maximum width of the flexible mop 222 protruding from the outer edge of the stop plate 231 is greater than 5 mm, during the operation of the cleaning device 100, the flexible mop 222 is prone to phenomena such as snagging with objects in the space, and it is not convenient to stably install the flexible mop 222 on the mop bracket 221. When the cleaning device 100 is working, it is prone to jamming. It can be seen that by making the maximum spacing width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 satisfy the relationship 0 ≤ L ≤ 5 mm in the present application, it is not only convenient for cleaning the edge of the obstacle, but also convenient to stably install the flexible mop 222 on the mop bracket 221, preventing the flexible mop 222 from snagging with the obstacle or other objects in the space, and improving the operation stability and reliability of the cleaning device 100.

[0074] It should be noted that the maximum width L of the flexible mop 222 protruding from the outer edge of the stop plate 231 in the present application is the maximum width when the cleaning device 100 is in a natural state. The cleaning device 100 being in a natural state means that the cleaning device 100 is placed on a horizontal ground, the flexible mop 222 is in contact with the ground, and the flexible mop 222 is not under extrusion pressure.

[0075] During actual assembly, the flexible mop 222 in the present application is detachably installed at the bottom of the mop bracket 221 through Velcro. In this way, it is convenient to detach the flexible mop 222 for cleaning or replacement. Of course, in other embodiments of the present application, the flexible mop 222 can also be detachably installed on the mop bracket 221 through fasteners such as buckles, magnetic attractions, and screws. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0076] Combined with Figures 1 to 10 As shown, the stop plate 231 in the present application includes a circular plate or a sector plate. The case where the stop plate 231 is a sector plate is shown in the drawings of the present application. By setting the stop plate 231 as a sector plate in the present application, the occupied space of the stop plate 231 in the cleaning device 100 can be reduced to a certain extent, which is convenient for avoiding other components on the cleaning device 100, and then facilitating the realization of the lightweight and miniaturized design of the cleaning device 100, and can also reduce the material cost of the cleaning device 100.

[0077] See Figures 10 to 12As shown, the mop bracket 221 in the present application includes a mop bracket 221. Within the projection of the main body 10 in the height direction, the stop plate 231 has a convex arc portion 23101 protruding from the mop bracket 221. The convex arc portion 23101 extends along the outer periphery of the mop bracket 221. In actual design, the minimum central angle of the convex arc portion 23101 is A, and A is the included angle between the first radius line X and the second radius line Y. Among them, the first radius line X is the connection line between the center O of the mop bracket and the first tangent point B1. The first tangent point B1 is the tangent point formed when the mop bracket 221 expands outward to be tangent to the first tangent line R1 at the outermost edge in a predetermined direction of the main body 10, and the first tangent line R1 is parallel to the moving direction of the main body 10. The second radius line Y is the connection line between the center O of the mop bracket and the second tangent point B2. The second tangent point B2 is the tangent point between the mop bracket 221 and the second tangent line R2 when the mop bracket 221 expands to the limit position. The second tangent line R2 is a tangent line passing through the point on the mop bracket 221 that is farthest from the main body 10 in the predetermined direction and is parallel to the first tangent line R1. It can be understood that the limit position described in the present application refers to the position where the mop bracket 221 expands to the position that is farthest from the outermost edge in a predetermined direction of the main body 10.

[0078] In the present application, by making the minimum central angle of the convex arc portion 23101 be A and making A be the included angle between the first radius line X and the second radius line Y, thus, when the cleaning device 100 is moving, when the first cleaning component 22 expands to the outer edge of the main body 10, the first stop component 23 can contact the obstacle prior to the mop bracket 221, and the situation where the obstacle hits the mop bracket 221 will not occur. In addition, when designing the stop plate 231, it only needs to be ensured that there is a convex arc portion 23101 on the stop plate 231 that protrudes from the mop bracket 221 and the central angle corresponding to the convex arc portion 23101 is greater than or equal to A, which can optimize the size of the stop plate 231. Furthermore, when the first stop component 23 contacts the obstacle prior to the mop bracket 221, the size of the first stop component 23 can be reasonably designed to be the smallest, so that the first stop component 23 can effectively avoid other components on the cleaning device 100.

[0079] Furthermore, referring to Figure 3 、 Figure 8 and Figure 11 as shown, along the predetermined direction of the main body 10, there is a predetermined distance S between the second tangent line R2 and the first tangent line R1. The predetermined distance S is the distance between the second tangent line R2 and the first tangent line R1 when the first cleaning component 22 expands to the position that is farthest from the main body 10.

[0080] Specifically, the predetermined direction of the main body 10 is that the main body 10 is in Figure 3 、 Figure 8 and Figure 11When in the state, the direction is from the left side of the host 10 to the right side of the host 10, and this predetermined direction is perpendicular to the moving direction of the host 10. In this application, the size of the predetermined distance S can be reasonably selected according to the sizes of the host 10 and the first cleaning component 22. On the premise that the rotation center of the first cleaning component 22 protrudes beyond the outer edge of the host 10, by reasonably adjusting the size of the predetermined distance S, the limit position of the first cleaning component 22 expanding relative to the host 10 can be reasonably arranged. In this way, the cleaning range of the first cleaning component 22 can be controlled. Thus, for different types of cleaning devices and cleaning environments, by reasonably selecting the size of the predetermined distance S, the first cleaning component 22 can have a better cleaning effect after expansion. At the same time, in order to enable the first cleaning component 22 to better perform the cleaning task when it expands to the limit position, in this application, after the first cleaning component 22 expands to the limit position, the structure of the first cleaning mechanism 20 can be optimized so that the first cleaning component 22 can move back and forth in the direction where the second tangent R2 is located, so that the first cleaning component 22 has a degree of freedom parallel to the moving direction of the host 10, and further enables the first cleaning component 22 to be more flexible when performing the cleaning task, which can improve the cleaning efficiency of the cleaning device to a certain extent.

[0081] Further, as shown in Figure 11 , Figure 19 and Figure 21 a rotating part 11 is provided on the host 10, and the maximum expansion angle α of the first cleaning component 22 is less than 180°. Among them, within the projection in the height direction of the host 10: when the first cleaning component 22 is in the retracted position, the connecting line between the center O of the mop bracket and the rotating part 11 is J1, and when the first cleaning component 22 expands to the limit position, the connecting line between the center O of the mop bracket and the rotating part 11 is J2, and the maximum expansion angle α is the included angle between J1 and J2.

[0082] Specifically, the setting of the rotating part 11 facilitates the installation of the first cleaning mechanism 20 on the host 10 and enables the first cleaning mechanism 20 to rotate relative to the host 10, so that the first cleaning component 22 can be switched between the expanded position and the retracted position, and further enables the first cleaning component 22 to be more flexible when performing the cleaning task, and also enables the cleaning device to meet the cleaning requirements of more scenarios. As Figure 21As shown, when the first cleaning component 22 is in the retracted position, the projection of the center of the mop bracket in the height direction of the main body is O1. At this time, the connecting line between the center O1 of the mop bracket and the rotating part 11 is J1. When the first cleaning component 22 is expanded to the extreme position, the projection of the center of the mop bracket in the height direction of the main body is O2. At this time, the connecting line between the center O2 of the mop bracket and the rotating part 11 is J2. In this application, the reason for limiting the angle between J1 and J2 (i.e., the maximum expansion angle α) to be less than 180° is that such a setting method can facilitate the conversion of the first cleaning component 22 between the expanded position and the retracted position. If the maximum expansion angle α is equal to 180°, at this time, a dead point will occur during the conversion of the first cleaning component 22 from the expanded position to the retracted position, resulting in an unclear swinging direction of the first cleaning component 22. If the maximum expansion angle α is greater than 180°, it will cause interference between the first cleaning component 22 and other structures of the cleaning device (such as the moving wheel set 68). In order to prevent interference between the structures of the cleaning device, a larger space needs to be reserved for the first cleaning mechanism 20, resulting in an increase in the size of the main body 10. Therefore, in this application, the maximum expansion angle α of the first cleaning component 22 is set to be less than 180°.

[0083] Combined with Figures 1 to 5 As shown, a rotating part 11 and an elastic member 12 are provided on the main body 10. The first cleaning mechanism 20 is rotatably connected to the main body 10 through the rotating part 11 to drive the first cleaning component 22 to move between the expanded position and the retracted position. The elastic member 12 expands and contracts along the rotation direction of the rotating part 11, and both ends of the elastic member 12 are respectively connected to the first cleaning mechanism 20 and the main body 10. Exemplarily, the elastic member 12 in this application can be a spring, an elastic rubber strip, etc. Through the action of the elastic member 12, during the process of an obstacle applying a force to the first cleaning mechanism 20, the elastic member 12 can maintain the current position of the first cleaning mechanism 20, which is more suitable for enabling the flexible mop 222 on the first cleaning component 22 to continuously contact the edge of the obstacle to perform a cleaning operation. That is to say, the setting of the elastic member 12 can make the flexible mop 222 of the first cleaning component 22 abut against the obstacle for edge cleaning and facilitate the flexible recovery of the first cleaning component 22.

[0084] Optionally, refer to Figure 22As shown, another embodiment of the present application shows another implementation manner of the elastic member 12. Both ends of the elastic member 12 are respectively connected to the host 10 and the first cleaning mechanism 20. The first cleaning mechanism 20 rotates in the first direction or the second direction to drive the elastic member 12 to swing and stretch. Specifically, different from the above-described setting manner in which the elastic member 12 expands and contracts along the rotation direction of the rotating portion 11, the elastic member 12 here does not expand and contract along the rotation direction of the rotating portion 11, but swings around the end of the elastic member 12 and stretches along the length direction of the elastic member 12. Through the action of the elastic member 12, during the process of the obstacle applying a force to the first cleaning mechanism 20, the elastic member 12 can maintain the current position of the first cleaning mechanism 20 through the elastic force, and is more suitable for making the flexible mop 222 on the first cleaning member 22 continuously contact the edge of the obstacle to perform the cleaning operation. In addition, when the first cleaning member 22 needs to move from the outward expansion position to the inward retraction position, the setting of the elastic member 12 can make the first cleaning member 22 achieve flexible recovery through the elastic force, avoiding damage to the first cleaning member 22 or other components on the cleaning device due to mechanical impact.

[0085] As Figure 5 shown, in order to limit and guide the elastic member 12, an arc-shaped groove 13 is provided on the host 10 of the present application. The center of the arc-shaped groove 13 coincides with the rotation center of the rotating portion 11. The elastic member 12 is installed in the arc-shaped groove 13 and can expand and contract along the extension direction of the arc-shaped groove 13. Optionally, both ends of the elastic member 12 in the present application can be respectively fixed to the host 10 and the first cleaning mechanism 20 by means of hooks, buckles, welding, etc. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0086] Optionally, referring to Figure 22 shown, for the above-described setting manner in which the elastic member 12 swings and stretches during operation: a first connection portion 15 is provided on the host 10, a second connection portion 16 is provided on the first cleaning mechanism 20, one end of the elastic member 12 is connected to the first connection portion 15, and the other end of the elastic member 12 is connected to the second connection portion 16. When the first cleaning member 22 is in the inward retraction position, the elastic member 12 is in a stretched state, and during the process of the first cleaning member 22 converting from the inward retraction position to the outward expansion position, the stretching amount of the elastic member 12 gradually increases.

[0087] Specifically, the arrangement of the first connecting portion 15 and the second connecting portion 16 provides a suitable installation position for the elastic member 12. When the first cleaning member 22 is in the retracted position, the elastic member 12 is in a stretched state, and during the process of the first cleaning member 22 being converted from the retracted position to the outward expansion position, the stretching amount of the elastic member 12 gradually increases. In other words, the stretching amount of the elastic member 12 when the first cleaning member 22 is in the outward expansion position is greater than the stretching amount of the elastic member 12 when the first cleaning member 22 is in the retracted position, so that the first cleaning member 22 can have a tendency to move to the retracted position when it is in the outward expansion position. If the external force that maintains the first cleaning member 22 in the outward expansion position decreases or disappears, the first cleaning member 22 can automatically retract to the retracted position under the action of the elastic member 12, ensuring that the device can operate flexibly in a complex environment. This embodiment shows the case where the elastic member 12 is a tension spring, and the specific structure of the elastic member 12 can be reasonably adjusted according to actual conditions.

[0088] Further, see Figure 4 , Figure 5 as well as Figure 10 As shown, the first power component 21 in the present application includes a first driving member 211 and a first transmission assembly 212. The first driving member 211 is rotatably mounted on the bottom shell 17 through the rotating part 11, and the first driving member 211 has a rotating shaft, which is coaxially arranged with the rotating part 11; the first transmission assembly 212 is connected between the first driving member 211 and the first cleaning member 22, and the rotation of the rotating shaft drives the first transmission assembly 212 to drive the first cleaning member 22 to rotate in the first direction or the second direction. Specifically, the first driving member 211 in the present application includes a motor, and the rotating shaft of the motor is coaxially arranged with the rotating part 11. In this way, the space occupied by the first power component 21 when it swings relative to the main machine 10 can be optimized, which is more suitable for a reasonable layout of the parts on the cleaning device 100.

[0089] Alternatively, see Figure 19 , Figure 20 as well as Figure 22 As shown, in another embodiment of the present application, the rotating shaft is staggered with the rotating part 11 and the first driving member 211 can swing around the rotating part 11. Such a configuration not only facilitates the layout of the first driving member 211 and the first transmission assembly 212, making the internal structure of the host 10 more compact, but also facilitates the power transmission between the first driving member 211 and the first transmission assembly 212, and reduces the power loss of the first driving member 211 as much as possible.

[0090] Exemplarily, the rotating part 11 in the present application includes structures such as a rotating shaft. During actual installation, a bearing is installed on the first driving member 211, that is, the outer casing of the motor, and the bearing is fixed on the rotating shaft. As long as it is other deformation methods based on the conception of the present application, they are within the protection scope of the present application.

[0091] Further, referring to Figures 19 to 22 As shown, the first cleaning member 22 is located at the bottom of the main body 10. An avoidance notch 14 is provided on the main body 10. The avoidance notch 14 extends from the inner side of the main body 10 towards the edge of the main body 10, and an opening is provided at one end of the avoidance notch 14 close to the edge of the main body 10. The first cleaning mechanism 20 moves along the avoidance notch 14 to move between an outward expansion position and an inward retraction position. The opening is at least used to avoid the first cleaning mechanism 20 to allow the rotation center of the first cleaning member 22 to be located outside the main body 10 when the first cleaning member 22 is in the outward expansion position. In some embodiments, within the projection in the height direction of the main body 10: when the maximum width M of the outer contour of the first transmission assembly 212 is less than or equal to the maximum outward expansion radius r from the rotating portion 11 to the avoidance notch 14, the maximum width M of the outer contour of the first transmission assembly 212 is arranged parallel to the direction of the maximum outward expansion radius r (i.e., the maximum radius from the rotating portion 11 to the edge of the avoidance notch 14) or intersects with the maximum outward expansion radius r. Specifically, the first cleaning member 22 is located at the bottom of the main body 10, which not only facilitates the first cleaning member 22 to clean the surface to be cleaned, but also prevents the first cleaning member 22 from interfering with other components of the cleaning device. At the same time, in order to enable the first cleaning member 22 to be connected to the first power member 21 and enable the first power member 21 to drive the first cleaning member 22 to swing relative to the main body 10, an avoidance notch 14 extending from the inner side of the main body to the edge of the main body is provided on the main body 10 of the present application, and the shape and size of the avoidance notch 14 can be reasonably adjusted according to the swinging direction and size of the first cleaning mechanism 20, so that the first cleaning mechanism 20 will not interfere with other structures (such as the moving wheel set 68) of the cleaning device during the process of swinging relative to the main body 10. In addition, in the present application, the arrangement manner of the first transmission assembly 212 on the main body 10 can be reasonably adjusted according to the size of the first transmission assembly 212, such as Figure 19 As shown, the first transmission assembly 212 in this embodiment is generally strip-shaped. Within the projection in the height direction of the main body 10: when the maximum width M of the outer contour of the first transmission assembly 212 (i.e., the maximum length of the strip-shaped first transmission assembly 212) is less than or equal to the maximum outward expansion radius r, the maximum width M of the outer contour of the first transmission assembly 212 is arranged along the outward expansion radius r of the first cleaning member 22 or intersects with the maximum outward expansion radius r.

[0092] Further, referring to Figure 12 、 Figure 13 and Figure 23As shown, the first transmission assembly 212 further includes a reduction gearbox 2311. The first stop member 23 includes a connecting portion 232 and a stop baffle 231. The connecting portion 232 is integrally formed with or fixedly connected to the outer shell of the reduction gearbox 2311, and the connecting portion 232 surrounds the outer perimeters of the first transmission member 2312 and the second transmission member 2313. The avoidance opening 2321 is located on the connecting portion 232. The stop baffle 231 is integrally formed with or fixedly connected to the connecting portion 232, and the stop baffle 231 covers a part of the outer perimeter of the first cleaning member 22. The power input end of the reduction gearbox 2311 is connected to the first driving member 211, and the power output end of the reduction gearbox 2311 is connected to the first transmission member 2312 to drive the first transmission member 2312 to rotate in the first direction or the second direction.

[0093] Specifically, the reduction gearbox 2311 is generally used to reduce the speed of the motor while increasing the output torque, which means that by adjusting the speed and torque after the motor output, the rotational movement of the first transmission member 2312 can be more precisely controlled, and thus the cleaning operation of the first cleaning member 22 can be further controlled. The connecting portion 232 is integrally formed with or fixedly connected to the outer shell of the reduction gearbox 2311 and surrounds the outer perimeters of the first transmission member 2312 and the second transmission member 2313. Such a design helps to protect the first transmission member 2312 and the second transmission member 2313 from the influence of the external environment, such as dust and debris, and at the same time can prevent other components of the cleaning device 100 from interfering with the movement of the first transmission member 2312 and the second transmission member 2313. In addition, the stop baffle 231 is integrally formed with or fixedly connected to the connecting portion 232, and the stop baffle 231 covers a part of the outer perimeter of the first cleaning member 22. In this way, when the first cleaning member 22 is in the outward-expanded position for cleaning, the stop baffle 231 can come into contact with the wall or obstacles first, thereby providing good protection for the first cleaning member 22. In addition, the avoidance opening 2321 located on the connecting portion 232 can extend along the outer perimeter of the connecting portion 232, and the specific position and size of the avoidance opening 2321 on the connecting portion 232 can be reasonably adjusted according to the actual situation, as long as it is ensured that the first stop member 23 does not interfere with the movement of the limiting member 70. The power input end of the reduction gearbox 2311 is connected to the first driving member 211, and the power output end of the reduction gearbox 2311 is connected to the first transmission member 2312, so that the first driving member 211 can effectively drive the first transmission member 2312 to rotate in two directions (the first direction and the second direction) through the reduction gearbox 2311. Such a setting not only improves the operation flexibility, but also enhances the adaptability of the internal system of the cleaning device 100 and the cleaning efficiency of the cleaning device 100.

[0094] Further, refer to Figures 3 to 5 、 Figure 8 and Figure 13As shown, the first cleaning component 22 further includes a mop bracket 221 and a flexible mop 222. Within the projection of the main body 10 in the height direction, the flexible mop 222 protrudes beyond the outer edge of the mop bracket 221. The stop baffle 231 is located inside the flexible mop 222, and at least part of the stop baffle 231 protrudes beyond the outer edge of the mop bracket 221. In this way, when the first cleaning component 22 is in the outward expansion position for edge cleaning and encounters an obstacle, the edge of the flexible mop 222 can continue to clean the edge of the obstacle. If the first cleaning component 22 collides with the obstacle, the stop baffle 231 can contact the obstacle, thus providing good protection for the mop bracket 221 and also avoiding scratching of the mop bracket 221 and the obstacle (when the obstacle is a table leg or a wall surface, scratching needs to be prevented).

[0095] In some other embodiments, within the projection of the main body 10 in the height direction: when the maximum width M of the outer contour of the first transmission component 212 is greater than the maximum outward expansion radius r from the rotating part 11 to the avoidance notch 14, the maximum width M of the outer contour of the first transmission component 212 intersects with the maximum outward expansion radius r. Specifically, when the maximum width M of the outer contour of the first transmission component 212 is greater than the maximum outward expansion radius r, the maximum width M of the outer contour of the first transmission component 212 intersects with the outward expansion radius r of the first cleaning component 22. With such a setting, it can not only prevent the first transmission component 212 from interfering with other structures inside the cleaning device (such as the air pump 65), but also reduce the size of the avoidance notch 14 to a certain extent. Furthermore, the avoidance notch 14 can satisfy the installation of the first cleaning mechanism 20 and avoid the situation where the structural strength of the main body 10 is weakened due to the oversize of the avoidance notch 14. This embodiment shows the situation where the maximum width M of the outer contour of the first transmission component 212 is less than the maximum outward expansion radius r and the maximum width M of the outer contour of the first transmission component 212 intersects with the maximum outward expansion radius r.

[0096] Furthermore, referring to Figure 1 、 Figure 6 、 Figure 8 and Figure 10 as shown, the cleaning device further includes a cover plate assembly 50. The cover plate assembly 50 is arranged on the main body 10, and the cover plate assembly 50 has an open state in which the opening is opened when the first cleaning component 22 is converted from the retracted position to the outward expansion position, and the cover plate assembly 50 also has a covering state in which the opening is covered when the first cleaning component 22 is in the retracted position.

[0097] Specifically, the cover plate assembly 50 is located at the opening of the avoidance notch 14 and can open or cover the opening of the avoidance notch 14 according to the state of the first cleaning member 22 (i.e., the outward expansion position and the inward retraction position). The cover plate assembly 50 of the present application can be a single cover plate or two cover plates. Moreover, the cover plate of the present application can be a full soft glue cover plate (i.e., a cover plate made entirely of soft glue), or a combination of a hard cover plate and soft glue (abbreviated as a semi-soft glue cover plate). This embodiment shows the case where the cover plate assembly 50 includes two cover plates. In addition, the two cover plates can be automatically opened according to the state of the first cleaning member 22, or can be opened by the thrust generated during the swinging of the first cleaning mechanism 20. When the first cleaning member 22 moves from the outward expansion position to the inward retraction position, the two cover plates can automatically cover following the first cleaning mechanism 20, thereby covering the opening of the avoidance notch 14. Moreover, when the cover plate assembly 50 is switched between the open state and the covering state, the principle of the two cover plates to achieve the conversion between the open state and the covering state is different according to the structure of the two cover plates (i.e., whether the two cover plates are full soft glue cover plates or semi-soft glue cover plates). When the two cover plates are full soft glue cover plates, the two cover plates achieve the conversion between the open state and the covering state through the good elasticity of the soft glue. When the two cover plates are semi-soft glue cover plates, the two cover plates achieve the conversion between the open state and the covering state through elastic components such as torsion springs and the good elasticity of the soft glue. The use of soft glue can play a good protective role for the cover plate assembly 50, avoiding the cover plate assembly 50 from colliding with obstacles and being damaged. At the same time, the setting of the cover plate assembly 50 can prevent dust, debris, etc. from entering the interior of the main body 10, reduce the wear and faults of the internal parts of the main body 10, and extend the service life of the cleaning device.

[0098] Further, as shown in Figure 22 the cleaning device further includes a limiting member 70. The limiting member 70 has a first state of avoiding the first cleaning member 22 to allow the first cleaning member 22 to be converted between the inward retraction position and the outward expansion position, and the limiting member 70 also has a second state of blocking the first cleaning member 22 to prevent the first cleaning member 22 from being converted from the inward retraction position to the outward expansion position.

[0099] Specifically, when it is necessary for the first cleaning member 22 to move from the retracted position to the expanded position so that the first cleaning member 22 can perform edge cleaning, the limiting member 70 is switched from the second state to the first state. When the first cleaning member 22 does not need to perform edge cleaning, the first cleaning member 22 is in the retracted position. To prevent the first cleaning member 22 from being accidentally pulled out under the action of an external force, the limiting member 70 is switched from the first state to the second state. The limiting member 70 can be switched between the first state and the second state by means of rotation, movement, and swinging. This embodiment shows the situation where the limiting member 70 is switched between the first state and the second state by swinging. In this embodiment, the limiting member 70 includes a limiting member 71 and an elastic reset member 72. A positioning post 171 is provided on the bottom case 17. The positioning post 171 is located on the outer peripheral side of the avoidance notch 14. The limiting member 71 is sleeved on the positioning post 171 and can rotate around the limiting member 71, so that the limiting member 71 can be switched between the first state and the second state. The two ends of the elastic reset member 72 respectively abut against the main body bottom case 17 and the limiting member 71. The elastic reset member 72 can provide elastic force for the limiting member 71, so that the limiting member 71 can automatically return to the second state.

[0100] In some embodiments of the present application, the cleaning device 100 may be provided with only one cleaning mechanism, that is, the first cleaning mechanism 20 (as shown in FIGS. 1 to Figure 5 as shown). In some other embodiments of the present application, the cleaning device 100 may also be provided with multiple cleaning mechanisms, such as Figures 6 to 10As shown, the cleaning device 100 includes two cleaning mechanisms. For the convenience of driving, the cleaning mechanisms are respectively labeled as the first cleaning mechanism 20 and the second cleaning mechanism 30. When the cleaning device 100 has two cleaning mechanisms, the cleaning device 100 is configured as follows: When the first cleaning component 22 is in the retracted position, the rotation direction of the first cleaning component 22 is opposite to that of the second cleaning component 32; when the first cleaning component 22 is in the extended position, the rotation direction of the first cleaning component 22 is the same as or opposite to that of the second cleaning component 32. That is to say: When the first cleaning component 22 is in the retracted position, if the first cleaning component 22 of the first cleaning mechanism 20 rotates in the first direction, then the second cleaning component 32 of the second cleaning mechanism 30 rotates in the second direction; if the first cleaning component 22 rotates in the second direction, then the second cleaning component 32 rotates in the first direction. When the first cleaning component 22 is in the extended position, if the first cleaning component 22 rotates in the first direction, then the second cleaning component 32 can rotate in the first direction or the second direction; if the first cleaning component 22 rotates in the second direction, then the second cleaning component 32 can rotate in the second direction or the first direction. It should be noted that: The first direction can be the clockwise direction or the counterclockwise direction, and the second direction can be the clockwise direction or the counterclockwise direction. Specifically, it depends on which one of the first cleaning component 22 and the second cleaning component 32 can expand relative to the main body 10, such as Figure 7 As shown, if the cleaning component on the right side of the main body 10 (i.e., the first cleaning component 22) can expand relative to the main body 10, then the first direction is the clockwise direction and the second direction is the counterclockwise direction; if the cleaning component on the left side of the main body 10 (i.e., the second cleaning component 32) can expand relative to the main body 10, then the first direction is the counterclockwise direction and the second direction is the clockwise direction. This embodiment shows the situation where the cleaning component on the right side of the main body 10 (i.e., the first cleaning component 22) can expand relative to the main body 10.

[0101] Combined with Figures 6 to 10 、 Figures 12 to 14 As shown, in this cleaning device 100, when the first cleaning mechanism 20 is subjected to frictional torques in different directions (such as when the first cleaning mechanism 20 rotates and contacts the ground, the first cleaning mechanism 20 will be subjected to the frictional torque of the ground reaction), the first cleaning mechanism 20 can swing relative to the main body 10, thereby realizing the yaw of the first cleaning mechanism 20. At the same time, the rotation direction of the second cleaning mechanism 30 is opposite to that of the first cleaning mechanism 20, and the frictions received by the second cleaning mechanism 30 and the first cleaning mechanism 20 can cancel each other out, thereby ensuring the stability of the cleaning device 100 during operation.

[0102] When the cleaning device 100 has both the first cleaning mechanism 20 and the second cleaning mechanism 30, at least one of the first cleaning mechanism 20 and the second cleaning mechanism 30 can swing relative to the host 10. Figure 10 , it is shown that the first cleaning mechanism 20 can swing relative to the main body 10, while the second cleaning mechanism 30 cannot swing relative to the main body 10. Of course, in other embodiments of the present application, the second cleaning mechanism 30 can also swing relative to the main body 10. When the first cleaning mechanism 20 and the second cleaning mechanism 30 can both swing relative to the main body 10, the structures of the first cleaning mechanism 20 and the second cleaning mechanism 30 are consistent, but the rotation directions of the first cleaning component 22 and the second cleaning component 32 are opposite.

[0103] Further, see Figures 17 to 19 As shown, the first cleaning component 22 and the second cleaning component 32 are both located on the side of the main machine 10 away from the moving direction of the main machine 10. When the first cleaning component 22 is retracted to the retracted position, in the projection in the height direction of the main machine 10, the first cleaning component 22 and the second cleaning component 32 are symmetrical about the center line g of the main machine 10, and the projection of the first cleaning mechanism 20 and the projection of the second cleaning mechanism 30 partially overlap, and the center line g of the main machine 10 is parallel to the moving direction of the main machine 10.

[0104] Specifically, the moving direction of the main machine 10 is the direction to which the front end of the main machine 10 points when the main machine 10 moves forward in a straight line. The double cleaning effect of the first cleaning component 22 and the second cleaning component 32 ensures that the cleaning equipment covers and thoroughly cleans the surface to be cleaned, thereby improving the cleaning efficiency. At the same time, the symmetrical design of the first cleaning component 22 and the second cleaning component 32 enables the main machine 10 to evenly distribute the cleaning force during the movement, ensuring that the cleaning effect on both sides of the main machine 10 is consistent, avoiding omissions or uneven cleaning. The projections of the first cleaning component 22 and the second cleaning component 32 in the height direction of the main machine 10 partially overlap, which means that they (i.e., the first cleaning component 22 and the second cleaning component 32) can work together when working, and perform a deeper cleaning of the overlapping area, thereby improving the cleaning quality. The center line g is parallel to the moving direction of the main machine 10. This design enables the cleaning components (i.e., the first cleaning component 22 and the second cleaning component 32) to more effectively cover the cleaning path during the movement, reduce repeated cleaning or cleaning blind spots, and improve cleaning efficiency. In addition, the symmetrical cleaning components arranged along the moving direction enable the host 10 to clean a larger area when moving in a straight line, reducing the number of turns and direction adjustments, and further improving the cleaning efficiency. Moreover, the symmetrical layout of the first cleaning component 22 and the second cleaning component 32 about the center line g helps to maintain the stability of the host during movement, reduce shaking caused by center of gravity offset or uneven cleaning force, and improve user experience. The cleaning components are located on the side of the host away from the moving direction, and the projections overlap. This compact design can save installation space, making the host more compact and easy to operate in a small space, and avoid the appearance of cleaning dead corners (here mainly refers to the cleaning dead corners between the first cleaning component 22 and the second cleaning component 32), thereby improving the comprehensiveness of cleaning.

[0105] Further, see Figure 17 As shown, on the side away from the moving direction of the mainframe 10: the common tangent line L4 of the edge of the first cleaning member 22 and the edge of the second cleaning member 32 is flush with the tangent line L5 of the edge of the mainframe 10; or, the common tangent line L4 of the edge of the first cleaning member 22 and the edge of the second cleaning member 32 is closer to the inner side of the mainframe 10 than the tangent line L5 of the edge of the mainframe 10. The common tangent line L4 of the edge of the first cleaning member 22 and the edge of the second cleaning member 32 is parallel to the predetermined direction of the mainframe 10.

[0106] Specifically, when the first cleaning member 22 is in the retracted position, the common tangent line L4 of the edges of the first cleaning member 22 and the second cleaning member 32 is flush with or closer to the inner side of the host than the tangent line L5 of the host edge. This design ensures that the cleaning members (i.e., the first cleaning member 22 and the second cleaning member 32) can closely fit the edge of the host 10 during movement, thereby effectively covering the edge area, reducing cleaning dead corners, and improving cleaning efficiency. The common tangent line L4 is parallel to the predetermined direction of the host, which means that the cleaning members can evenly cover the surface to be cleaned along the predetermined direction during cleaning, thus ensuring the comprehensiveness and consistency of cleaning. Since the cleaning members can closely fit the edge and effectively cover it, the user does not need to operate the cleaning device to clean the same area multiple times, reducing repetitive labor and improving cleaning efficiency. The design of the edge being flush or retracted (i.e., the common tangent line L4 is flush with the tangent line L5 of the edge or the common tangent line L4 is closer to the inner side of the host 10 than the tangent line L5 of the edge) helps to maintain the stability of the host 10 during movement, reduce shaking or deviation caused by the protrusion or swing of the cleaning members, and ensure the safe operation of the cleaning device. At the same time, such a design can also make the overall host 10 more compact, facilitating operation in a narrow space (such as the host 10 rotating in place), and improving space utilization efficiency.

[0107] In this application, the case where the second cleaning mechanism 30 cannot swing relative to the host 10 is introduced in detail. In this embodiment, the second power member 31 of the second cleaning mechanism 30 is fixedly installed on the host 10, and the second power member 31 has a second driving member 311 and a second transmission assembly 312. Among them, the second driving member 311 is a driving motor, and both the second transmission assembly 312 and the first transmission assembly 212 include a reduction gearbox 2311, a first transmission member 2312, a second transmission member 2313, and an elastic element 2314. The first transmission member 2312 connects the reduction gearbox 2311 and the second transmission member 2313, the second transmission member 2313 connects the first cleaning member 22 or the second cleaning member 32, a track surface 23131 is provided on the second transmission member 2313, and the first transmission member 2312 is movably abutted against the track surface 23131, and the elastic element 2314 abuts against the second transmission member 2313 to apply a restoring force to the second transmission member 2313.

[0108] Among them, the reduction gearbox 2311 is configured to drive the first transmission member 2312 to rotate along the first direction and the second direction under the drive of the first driving member 211 or the second driving member 311, so that the first transmission member 2312 moves on the track surface 23131, and the first cleaning member 22 is lifted and lowered along the height direction of the host 10 and rotated along the first direction and the second direction.

[0109] In the initial state, the first cleaning component 22 and the second cleaning component 32 are at a relatively high position of the main machine 10, that is, the first cleaning component 22 and the second cleaning component 32 are off the ground or the table and are off the ground. When the reduction box 2311 drives the first transmission member 2312 to rotate along the first direction, the first transmission member 2312 is held against the track surface 23131 and rotates along the track surface 23131. The track surface 23131 in the present application is a convex arc surface. When the first transmission member 2312 moves from the low position to the high position along the track surface 23131, the first transmission member 2312 applies a resisting force to the second transmission member 2313, so that the second transmission member 2313 can move in a direction away from the first transmission member 2312, that is, move in a direction close to the ground along the height direction of the main machine 10, and then drive the first cleaning component 22 or the second cleaning component 32 connected to the second transmission member 2313 to move in a direction close to the ground. The second transmission member 2313 in the present application is provided with a limiting structure 23132. When the first cleaning member 22 and the second cleaning member 32 are in contact with the ground, the reduction box 2311 continuously drives the first transmission member 2312 to move along the height direction of the main machine 10. At this time, the side of the first transmission member 2312 is in contact with the limiting structure 23132. The second transmission member 2313 can be driven by the first transmission member 2312 to rotate along the first direction to clean the ground. In this process, the first cleaning mechanism 20 is subjected to the friction torque applied by the ground, and can swing relative to the main machine 10 in the second direction to drive the first cleaning member 22 to convert to the outward expansion position to clean the obstacles along the edge. Since the second driving member 311 of the second cleaning mechanism 30 is fixed, the second cleaning member 32 remains in the same position relative to the main machine 10 and performs the cleaning operation in situ. It should be noted that the rotation direction of the reduction box 2311 in the second cleaning mechanism 30 is always opposite to the rotation direction of the reduction box 2311 in the first cleaning mechanism 20, so as to ensure that the cleaning device 100 can run smoothly.

[0110] When the reduction box 2311 drives the first transmission member 2312 to rotate in a second direction opposite to the first direction, the first transmission member 2312 disengages from the limiting structure 23132, and the first transmission member 2312 rotates from the highest position of the track surface 23131 to the lowest position of the moving track surface 23131. During this process, the elastic element 2314 applies a reset force to the second transmission member 2313, that is, applies a supporting force away from the ground along the height direction of the main unit 10. At this time, the second transmission member 2313 rises in a direction away from the ground, thereby driving the first cleaning component 22 and the second cleaning component 32 to rise and leave the ground.

[0111] It can be seen that the first cleaning component 22 and the second cleaning component 32 in the present application can be raised and lowered, which is beneficial to protecting the ground and can reduce the difficulty of the cleaning device 100 to overcome obstacles.

[0112] Specifically, along the height direction of the host 10, the first transmission member 2312 can be connected below the reduction gearbox 2311. The first transmission member 2312 can be U-shaped, and the first transmission member 2312 is fixedly installed on the output shaft 23111 of the reduction gearbox 2311 or the motor. At this time, the output shaft 23111 of the motor or the reduction gearbox 2311 extends along the height direction of the host 10. The second transmission member 2313 is arranged in a cylindrical shape, and the second transmission member 2313 is sleeved on the output shaft 23111 and can move up and down relative to the output shaft 23111. The elastic element 2314 can be structures such as a spring or an elastic sleeve, and the elastic element 2314 can undergo elastic deformation. The elastic element 2314 is sleeved on the output shaft 23111, and a support block 23112 is arranged at the bottom end of the output shaft 23111. The two ends of the elastic element 2314 respectively abut against the second transmission member 2313 and the support block 23112. After the elastic element 2314 is compressed by the second transmission member 2313, it can recover its elastic deformation so that the elastic element 2314 elongates to push the second transmission member 2313 to move along the output shaft 23111. The first cleaning member 22 or the second cleaning member 32 is fixedly connected below the second transmission member 2313. The limiting structure 23132 is arranged on the inner or outer wall surface of the second transmission member 2313.

[0113] In this application, the track surface 23131 can be arranged on the outer peripheral surface of the second transmission member 2313 or on the inner wall surface of the second transmission member 2313. The attached Figure 14 of this application shows the case where the track surface 23131 is arranged on the outer peripheral surface of the second transmission member 2313. The limiting structure 23132 is arranged on the track surface 23131 and is located at the topmost position of the track surface 23131. The limiting structure 23132 in this application can be a convex block structure, and there are two such convex block structures, which are respectively arranged on opposite sides of the second transmission member 2313. During actual operation, the two ends of the U-shaped first transmission member 2312 respectively abut against the track surface 23131 between the two limiting structures 23132 and slide along the track surface 23131 to drive the second transmission member 2313 to move up and down in the first direction. When the two ends of the U-shaped first transmission member 2312 respectively stop against the two limiting structures 23132, the second transmission member 2313 moves up and down in the first direction to the limit position.

[0114] In some embodiments, please refer Figures 12 to 14As shown, the track surface 23131 includes a first area 23131a, a second area 23131b, a third area 23131c and a connecting area 23131d. In the circumferential direction of the second transmission member 2313, the first area 23131a, the second area 23131b and the third area 23131c are connected in sequence, and the second area 23131b is lower than the first area 23131a and the third area 23131c. Two adjacent areas can be connected through the connecting area 23131d, and the first transmission member 2312 can be moved from one area to another area through the connecting area 23131d. When the first transmission member 2312 abuts against the first area 23131a or the third area 23131c, the first cleaning member 22 or the second cleaning member 32 is in a cleaning position for abutting against the ground, and when the first transmission member 2312 abuts against the second area 23131b, the first cleaning member 22 or the second cleaning member 32 is in a ground-lifting position for detaching from the ground. In this way, the first cleaning member 22 or the second cleaning member 32 is switched between the off-ground position and the cleaning position through the three regions of the track surface 23131 .

[0115] Further, see Figures 18 to 20 , Figure 22 As shown, the cleaning device further includes an auxiliary component 60, which is disposed on the main unit 10, and an avoidance surface is provided on the auxiliary component 60, which is at least used to reserve space for the first cleaning component 22 or the second cleaning component 32 to swing between the retracted position and the expanded position, and the auxiliary component 60 includes a radar 61, a water tank 62, a universal wheel assembly 63, a dust collection box 64, an air pump 65, a first conveying channel 66, a second conveying channel 67, and at least one of a moving wheel group 68. The auxiliary component 60 includes a moving wheel group 68, and the moving wheel group 68 includes at least two moving wheels, and at least two moving wheels are spaced apart along a predetermined direction of the main unit 10, and the first cleaning mechanism 20 and the second cleaning mechanism 30 are closer to the side of the main unit 10 that is away from the moving direction than the moving wheels, and the first cleaning mechanism 20 and the second cleaning mechanism 30 are both spaced apart from the moving wheels. Specifically, the first cleaning mechanism 20 and the second cleaning mechanism 30 are located on the side of the main machine away from the moving direction and closer to the side than the moving wheel. This layout allows the first cleaning mechanism 20 and the second cleaning mechanism 30 to further clean the places that are not thoroughly cleaned by the middle sweeping mechanism 40 and other structures during the movement of the main machine 10 in the moving direction, and can also clean the path that the moving wheel group 68 passes through, ensuring that no moving wheel track will appear. The spacing between the cleaning mechanism (i.e., the first cleaning mechanism 20 and the second cleaning mechanism 30) and the moving wheel avoids mutual interference between the components, allowing them to each perform at their best and work together to complete the cleaning task.

[0116] Optionally, the auxiliary component 60 further includes a radar 61. The radar 61 is disposed on one side of the main body 10 near the moving direction and at the top of the main body 10. Both the first cleaning mechanism 20 and the second cleaning mechanism 30 are spaced apart from the radar 61. Specifically, the radar 61 is located at the top of the main body 10 and on one side near the moving direction. This position enables the radar 61 to more effectively detect obstacles ahead during the cleaning process, plan the cleaning path in advance, reduce collisions and repeated cleaning, thereby improving the cleaning efficiency. The first cleaning mechanism 20 and the second cleaning mechanism 30 are spaced apart from the radar 61, avoiding interference with the detection of the radar 61 during the operation of the cleaning mechanisms (i.e., the first cleaning mechanism 20 and the second cleaning mechanism 30), ensuring that the radar can accurately obtain environmental information and improving the navigation accuracy. It also avoids interference of the radar 61 with the cleaning mechanisms (because the first cleaning mechanism 20 has an outward expansion function and requires a certain swinging space). The radar position at the top helps to detect and identify obstacles earlier, especially low or hidden obstacles, thereby reducing the risk of equipment collision and enhancing safety. By detecting and planning the path in advance, the radar 61 can guide the cleaning device to avoid obstacles that may cause jams or damage, protecting the cleaning device from damage. At the same time, the efficient navigation and obstacle detection capabilities reduce the need for manual intervention during the cleaning process, improve the convenience of use, and also enable the cleaning device to better adapt to different environments and terrains. Especially in an environment with furniture and many obstacles, it can shuttle and clean more flexibly.

[0117] Optionally, the auxiliary component 60 further includes a water tank 62. The water tank 62 is disposed at one end of the main body 10 near the moving direction, and the water tank 62 is close to the bottom of the main body 10 and is spaced apart from the first cleaning mechanism 20 and the second cleaning mechanism 30. Specifically, the water tank 62 is close to the bottom of the main body 10, facilitating the supply of water to the first cleaning component 22 and the second cleaning component 32, supporting the wet mopping function, and improving the floor cleaning effect. The water tank 62 is located at one end of the main body 10 near the moving direction and close to the bottom, which helps to lower the center of gravity of the cleaning device and enhance the stability during the operation of the cleaning device. Since the water tank 62 is spaced apart from the cleaning mechanisms (i.e., the first cleaning mechanism 20 and the second cleaning mechanism 30), it can avoid structural collision or interference between the water tank 62 and the cleaning mechanisms during the cleaning process, ensuring the safe operation of the cleaning device.

[0118] Optionally, the auxiliary component 60 also includes a universal wheel assembly 63, which is arranged on one end of the main machine 10 close to the moving direction and located at the bottom of the main machine 10, and the first cleaning mechanism 20 and the second cleaning mechanism 30 are both spaced apart from the universal wheel assembly 63. Specifically, the universal wheel assembly 63 enables the cleaning equipment to move freely in any direction, easily realize turning and adjusting direction, and enhance maneuverability in complex environments. The universal wheel assembly 63 facilitates the equipment to shuttle between narrow passages or furniture, improves the cleaning coverage, and reduces dead angles. The universal wheel assembly 63 helps the cleaning equipment to move accurately during the cleaning process, ensures that the cleaning mechanism can effectively cover the target area, and avoids repeated cleaning or omissions. The universal wheel assembly 63 located at the bottom of the main machine 10 can provide stable support for the main machine 10, maintain the balance of the cleaning equipment during the cleaning process, and prevent tilting or tipping. The universal wheel assembly 63 is arranged at one end close to the moving direction and is spaced apart from the cleaning mechanism, which can not only effectively utilize the bottom space of the main unit 10 and facilitate the layout of other components, but also prevent the universal wheel assembly 63 from colliding or interfering with the cleaning mechanism during operation, thereby ensuring the normal operation of various components of the cleaning equipment.

[0119] Optionally, the auxiliary component 60 further includes a dust box 64, which is disposed at one end of the main machine 10 away from the moving direction and close to the top of the main machine 10, and the first cleaning mechanism 20 and the second cleaning mechanism 30 are both spaced apart from the dust box 64, and the first cleaning mechanism 20 and the second cleaning mechanism 30 are closer to the end of the main machine 10 away from the moving direction than the dust box 64. Specifically, the dust box 64 is disposed at one end of the main machine 10 away from the moving direction and close to the top of the main machine 10, which makes it easy for people to remove the dust box 64 from the main machine 10 for regular maintenance and cleaning, and because the first cleaning mechanism 20 and the second cleaning mechanism 30 are both spaced apart from the dust box 64, mutual interference between the structures can be effectively prevented, ensuring that the first cleaning mechanism 20, the second cleaning mechanism 30 and the dust box 64 can complete their respective tasks, and assist the cleaning device in completing the cleaning work. The first cleaning mechanism 20 and the second cleaning mechanism 30 are closer to the end of the main unit 10 that is away from the moving direction than the dust box 64, which not only facilitates the cleaning mechanism (i.e., the first cleaning mechanism 20 and the second cleaning mechanism 30) to perform cleaning work, but also facilitates the outward expansion of the first cleaning component 22 relative to the main unit (i.e., the first cleaning component 22 is converted from an inward position to an outward position).

[0120] Optionally, the auxiliary component 60 further includes an air pump 65. The air pump 65 is disposed on the main body 10 and on a side of the dust collection box 64 away from the moving direction, and the air pump 65 is located between the first cleaning mechanism 20 and the second cleaning mechanism 30. The dust collection box 64 is communicated with the suction end of the air pump 65. The air pump 65 is closer to an end of the main body 10 away from the moving direction than the dust collection box 64. The first cleaning mechanism 20 and the second cleaning mechanism 30 are both spaced apart from the air pump 65. Specifically, the air pump 65 is disposed on the main body 10 and is closer to an end of the main body 10 away from the moving direction than the dust collection box 64, and the air pump 65 is located between the first cleaning mechanism 20 and the second cleaning mechanism 30. Such a setting can make the structure of the cleaning device more compact and facilitate space saving. And the cleaning mechanism is spaced apart from the air pump 65. In this way, a better installation position can be provided for the air pump 65, and the air pump 65 can be prevented from interfering with the cleaning mechanism, ensuring that each structure can play its respective role.

[0121] Optionally, the auxiliary component 60 further includes a first conveying channel 66. The first conveying channel 66 is disposed on the main body 10 and on a side of the air pump 65 close to the first cleaning mechanism 20. The dust collection box 64 is communicated with the first conveying channel 66. The dust collection box 64 includes a dust conveying channel 641. A first bending section 661 is provided on the first conveying channel 66 to avoid the first cleaning mechanism 20, and the first conveying channel 66 is spaced apart from the first cleaning mechanism 20. Specifically, the first conveying channel 66 is spaced apart from the first cleaning mechanism 20 and has a first bending section 661 that can avoid the first cleaning mechanism 20. The setting of the first conveying channel 66 enables the base station (not shown in the figure) of the cleaning device to blow air into the dust collection box 64 through the first conveying channel 66 when collecting the garbage inside the dust collection box 64. The dust conveying channel 641 is communicated with the dust collection end of the base station, and the dust collection end of the base station has a suction function. Through the cooperation of the first conveying channel 66 and the dust conveying channel 641, a circulating air flow can be formed, so that the garbage in the dust collection box 64 can be better collected into the base station.

[0122] Optionally, the auxiliary component 60 further includes a second conveying channel 67 disposed on the main body 10 and on a side of the air pump 65 close to the second cleaning mechanism 30. The air pump 65 is communicated with the second conveying channel 67. A second bending section 671 is provided on the second conveying channel 67 to avoid the second cleaning mechanism 30, and the second conveying channel 67 is spaced apart from the second cleaning mechanism 30. Specifically, the second conveying channel 67 is spaced apart from the second cleaning mechanism 30 and has a second bending section 671 that can avoid the second cleaning mechanism 30. The setting of the second conveying channel 67 enables the air generated by the air pump 65 to continuously discharge from the second conveying channel 67, and the suction end of the air pump 65 is communicated with the dust collection box 64, so as to help the dust collection box 64 better collect the garbage cleaned by the cleaning device, which is convenient for later centralized treatment or unified collection into the base station.

[0123] Exemplarily, this embodiment shows a case where the auxiliary component 60 includes a radar 61, a water tank 62, a universal wheel assembly 63, a dust collection box 64, an air pump 65, a first conveying channel 66, a second conveying channel 67, and a moving wheel set 68. Specifically, the collaborative work of the dust collection box 64, the air pump 65, the first conveying channel 66, and the second conveying channel 67 ensures that the garbage and dust collected by the middle sweeping mechanism 40 can be efficiently sucked and stored in the dust collection box 64, improving the cleaning efficiency of the cleaning device. Such a setting can not only ensure that the structure of the cleaning device is more compact and facilitate saving installation space, but also avoid interference of the first conveying channel 66 and the second conveying channel 67 with the cleaning mechanism. Thus, while ensuring the full utilization of the internal space of the host 10, it also avoids mutual interference between the various structures of the cleaning device, and further enables the cleaning device to operate safely and stably.

[0124] Combined with Figures 1 to 22 As shown, the cleaning device 100 in the present application further includes a middle sweeping mechanism 40, wherein the middle sweeping mechanism 40 is disposed at the center of the bottom of the host 10, and the moving wheel set 68 is disposed at the bottom of the host 10. The moving wheel set 68 is driven by a driving mechanism such as a motor. During actual operation, by controlling the driving mechanism such as the motor, the host 10 can be driven to move in space. During this process, through the action of the first power component 21 and the second power component 31, the first cleaning component 22 and the second cleaning component 32 can be driven to lift and rotate to clean the ground or tabletop, etc. At the same time, the frictional torque generated during the rotation of the first power component 21 driving the first cleaning component 22 can drive the first cleaning component 22 to expand outward to clean the edge of the obstacle. In addition, when the first cleaning mechanism 20 rotates relative to the host 10, the first stop component 23 can move synchronously with the first cleaning mechanism 20. When the first cleaning component 22 approaches the obstacle, the first stop component 23 can contact the obstacle in the space, which can prevent the first cleaning component 22 from scratching the obstacle during the edge cleaning process, and is convenient for cleaning the edge of the obstacle to avoid situations such as missed cleaning. In addition, when the first cleaning component 22 contacts the obstacle, it can exert a reaction force on the first cleaning mechanism 20 to drive the first cleaning mechanism 20 to drive the first cleaning component 22 to retract inward and move in the direction of the retracted position, enabling the first cleaning mechanism 20 to achieve flexible retraction, and enabling the first cleaning mechanism 20 to achieve retraction without adding additional detection mechanisms and control logics, with a simple structure, which can effectively improve the use comfort and design cost of the cleaning device 100.

[0125] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0126] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0127] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
