[0063] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0064] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] The cleaning device 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, according to the cleaning device 100 of the embodiment of the present invention, the cleaning device 100 includes: a base station 10 and a sweeping device 20.

[0067] The base station 10 is provided with a trigger 111. The sweeping device 20 includes a main body 21, a cover 22 and a linkage assembly 23. The cover 22 is provided on the main body 21. The cover 22 can be switched between a closed state and an open state. The cover 22 is always kept in a closed state. The linkage assembly 23 is provided on the main body 21. The linkage assembly 23 is connected to the cover 22. By switching the cover 22 between the closed state and the open state, it is convenient to replace parts of the sweeping device 20, empty garbage, charge, and other operations. For example, the component is a mopping module in the sweeping device 20. After cleaning, the mopping module is covered with a lot of dust. The sweeping device 20 can replace the clean mopping module in the base station 10; or, the sweeping device 20 is provided with a space for placing garbage. The cover 22 covers this space to prevent garbage from spilling during cleaning. The sweeping device 20 empties the garbage in the base station 10; or, the sweeping device 20 is provided with a charging port. The cover 22 covers the charging port to prevent foreign objects from clogging it or human contact. The sweeping device 20 enters the base station 10 and opens the cover 22 to expose the charging port for charging.

[0068] Among them, when the sweeping device 20 enters the base station 10 in the front-to-back direction, the trigger member 111 triggers the linkage assembly 23 and drives the cover 22 to switch to the open state; when the sweeping device 20 moves out of the base station 10 in the front-to-back direction, the cover 22 is reset to the closed state. When the sweeping device 20 enters and exits the base station 10, the cover 22 can be automatically opened through the cooperation of the linkage assembly 23 and the trigger member 111 to complete the corresponding functions, such as replacement of parts, emptying of garbage, charging, etc. After completing the corresponding functions, when the sweeping device 20 leaves the base station 10, the trigger member 111 gradually moves away from the linkage assembly 23, so that the cover 22 can be automatically closed. Since the opening and closing of the cover 22 only depends on the cooperation between the trigger member 111 and the linkage assembly 23, the structure is simple and the cost can be reduced. At the same time, the whole process does not require manual operation by the user, which improves the automation level of the cleaning device 100 and improves the user experience. It can be understood that the front-to-back direction is the direction in which the sweeping device 20 enters the base station 10.

[0069] It should be noted that the automatic closing of the cover body 22 may be due to the effect of its own gravity, and the cover body 22 changes from an open state to a closed state under the effect of its own gravity; or, the automatic closing of the cover body 22 may also be due to the effect of the base station 10 or other components, and the base station 10 or other components apply downward pressure to the cover body, causing the cover body 22 to change from an open state to a closed state.

[0070] According to the cleaning device 100 of the embodiment of the present invention, the automatic opening and closing of the cover 22 is achieved through the cooperation of the linkage component 23 and the trigger member 111, without the need for the user to manually open and close the cover 22, thereby simplifying the operation and improving the user experience.

[0071] like Figure 3 , Figure 5 , Figure 7 As shown, in some embodiments, the cover 22 is pivotally mounted on the main body 21, and the linkage assembly 23 includes a traction rope 233. The traction rope 233 is driven to move when the trigger 111 triggers the linkage assembly 23, and the sweeping device 20 is positively correlated with the rotation angle of the cover 22 to switch to the open state. The force of the trigger 111 is transmitted to the cover 22 through the traction rope 233, so that the cover 22 can be opened gradually. For example, when the sweeping device 20 gradually approaches the base station, the trigger 111 pulls the cover 22 to switch to the open state through the traction rope 233, and as the travel distance of the sweeping device 20 increases, the rotation angle of the cover 22 increases.

[0072] like Figure 3 , Fig.11As shown, in some embodiments, the cover body 22 includes a cover body 222, a pivoting portion 223 connected to the cover body 222, the pivoting portion 223 is rotatably connected to the main body 21 around the pivot axis, the cover body 222 or the pivoting portion 223 is provided with a force-applying portion 2231, the linkage assembly 23 is connected to the force-applying portion 2231 to provide a driving force, and when the trigger 111 triggers the linkage assembly 23, the linkage assembly 23 applies a force to the force-applying portion 2231 to drive the cover body 222 to rotate from front to back around the pivot axis, so as to switch the cover body 22 from a closed state to an open state, and the switch between the open state and the closed state of the cover body 22 is achieved by setting the cover body 222 to rotate from front to back around the pivot axis, so that the movement of the cover body 22 is more stable. For example, the cover body 222 is provided with a force-applying portion 2231 to facilitate rotation; or the pivoting portion 223 is provided with a force-applying portion 2231, which is closer to the pivot axis to reduce the driving force for rotation. It should be noted that the force-applying portion 2231 is the part where the linkage assembly 23 applies force to the cover body 22. The force-applying portion 2231 can also be set at other parts of the cover body 22, as long as the cover body 22 can be driven to rotate by applying force to the force-applying portion 2231. In some embodiments, a trigger position is provided on the main body 21, and the trigger member 111 is at the trigger position to trigger the linkage assembly 23. The trigger position is located below the pivot axis. By setting the trigger position below the pivot axis, the structural design of the linkage assembly 23 is facilitated, and the cover body 22 is convenient for rotation under force.

[0073] like Figure 5 , Fig.12 As shown, in some embodiments, the cover body 222 has a height H set in the up-down direction, and the distance between the force-applying part 2231 and the pivot axis is D, where D≥1 / 2H. Through the above arrangement, the force-applying part 2231 has a certain distance from the pivot axis to form a longer force arm, which facilitates the linkage component 23 to apply force to drive the cover body 22 to rotate. For example, D=1 / 2H; or, D=H.

[0074] like Figure 6 As shown, in some embodiments, the force-applying portion 2231 is located below the pivot axis. When the cover body 22 is switched from a closed state to an open state, the driving force provided by the linkage assembly 23 to the force-applying portion 2231 causes the cover body 222 to rotate backward and upward. The force-applying portion 2231 is rotated under force to form a torque, which provides an upward and forward driving force to the cover body 222, thereby driving the cover body 222 to rotate backward and upward.

[0075] like Figure 3 , Figure 5 and Figure 7 and Fig.16As shown, in some embodiments, the linkage assembly 23 includes a mounting wheel 232, a traction rope 233 and a moving member 231. A slideway 211 is provided on the main body 21. The traction rope 233 is respectively connected to the force-applying portion 2231 and the moving member 231 and is slidably in contact with the mounting wheel 232. During the process of the sweeping device 20 moving forward into the base station 10, the trigger member 111 pushes the moving member 231 to move along the slideway 211 and pulls the traction rope 233, thereby driving the force-applying portion 2231 to rotate around the pivot axis and driving the cover body 22 to switch from a closed state to an open state. The moving member 231 is pushed to move by the trigger member 111, and then the force-applying portion 2231 is pushed by the moving member 231 to open the cover body 22, forming a "movable pulley structure". The use of this structure can double the force of the moving member 231 on the force-applying portion 2231, so that the cover body 22 can be opened relatively easily. At the same time, all components in the entire movement process are mechanical structures, which improves reliability. The traction rope 233 itself is relatively small in size, which reduces the weight of the overall structure and simplifies the overall structure, further reducing the cost.

[0076] like Figure 5 As shown, in some embodiments, the pivot portion 223 is provided with a swing arm 221 protruding downward, the force-applying portion 2231 is provided on the swing arm 221, the mounting wheel 232 is provided on the main body 21 and is located in front of the force-applying portion 2231, the movable member 231 is located behind the mounting wheel 232 and is movably provided on the slide 211 along the front-rear direction, the swing arm 221 is recessed downward through the pivot portion 223, and the force-applying portion 2231 is provided on the swing arm 221, so as to facilitate the force-applying portion 2231 to be subjected to force and reduce the resistance to opening the cover body 22.

[0077] like Figure 6 As shown, in some embodiments, the traction rope 233 has a first fixed portion 2331, a second fixed portion 2332, a first movable portion 2333 and a second movable portion 2334 located between the first fixed portion 2331 and the second fixed portion 2332 along its extension direction, the first fixed portion 2331 is fixed to the mounting wheel 232 or the main body 21 and is located in front of the force-applying portion 2231, the second fixed portion 2332 is connected to the movable member 231, the first movable portion 2333 can move through the force-applying portion 2231, and the second movable portion 2334 can slide against the mounting wheel 232, and the traction rope 233 is pulled on the force-applying portion 2231 by the arrangement of the first movable portion 2333 and the second movable portion 2334, and the structure is simple and durable.

[0078] In some embodiments, the linkage assembly 23 further comprises an elastic member, one end of which extends backward beyond the moving member 231 and is connected to the main body 21, and the other end of which is connected to the moving member 231. The elastic member is often kept in a stretched state, so that the moving member 231 often maintains a tendency to move backward. The elastic member is provided to provide an auxiliary force, and the auxiliary force is arranged along the opening direction of the cover 22, so that the trigger 111 triggers the moving member 231, so that it is easier to open the cover 22, and the difficulty of opening the cover 22 is reduced. The elastic member is often kept in a stretched state, and the elastic member has a pulling force on the moving member 231, and the pulling force pulls the moving member 231 to move in the direction of opening the cover 22, but the pulling force is only an auxiliary force, and when the moving member 231 is not pushed by the trigger 111, the pulling force cannot move the moving member 231. For example, the elastic member is a rubber band, a spring, etc., which is low in cost and easy to replace.

[0079] like Figure 3 As shown, in some embodiments, the trigger member 111 is a boss extending in the front-to-back direction, and the boss is formed with a trigger portion 112. When the sweeping device 20 enters the base station 10 in the front-to-back direction, the trigger portion 112 pushes the moving member 231 to move to trigger the linkage assembly 23. By setting the boss to form a trigger portion 112 to push the moving member 231 to move, the probability of the moving member 231 contacting the trigger member 111 is increased, and the trigger member 111 and the moving member 231 are prevented from crossing each other, thereby improving the stability of the normal operation of the cleaning device 100.

[0080] like Figure 3 , Figure 5As shown, in some embodiments, the trigger portion 112 is constructed as an inclined surface at the rear end of the boss inclined in the up-down direction, and a staying space 212 connected to the slide 211 is provided on the main body 21, and the staying space 212 is correspondingly located above the trigger portion 112. When the trigger portion 112 pushes the moving member 231 to move in the slide 211 until the cover body 22 reaches the open state, the moving member 231 moves upward along the inclined surface of the trigger portion 112 to the staying space 212. By constructing the trigger portion 112 as an inclined surface, the contact between the trigger member 111 and the moving member 231 is facilitated, and the vibration when the trigger member 111 and the moving member 231 contact each other is reduced. At the same time, the force direction of the moving member 231 is changed, which facilitates the moving member 231 to move into the staying space 212. By setting the slide 211 to limit the sliding of the boss, the sweeping device 20 moves more smoothly. For example, the stay space 212 is at a higher position relative to the moving member 231, and the inclined surface faces obliquely upward. When the inclined surface pushes the moving member 231, the moving member 231 is pushed obliquely upward. When the moving member 231 moves to the bottom of the stay space 212, the moving member 231 moves into the stay space 212 under the push of the oblique upward force. Among them, when the cover body 22 reaches the open state, the moving member 231 stays in the stay space 212, and the sweeping device 20 is constructed to continue to move. The moving member 231 staying in the stay space 212 will not hinder the movement of the sweeping device 20, thereby facilitating subsequent operations, for example, the sweeping device 20 continues to move inward until it moves to the position for replacing the mopping module, or continues to move inward until the charging port contacts the base station 10 for charging.

[0081] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the slide 211 is recessed with a guide groove 2111, and the movable member 231 is provided with a roller 2311, and the roller 2311 rolls along the guide groove 2111. By setting the roller 2311 to roll in the guide groove 2111, the movable member 231 moves in the slide 211 by rolling, thereby reducing friction and reducing the difficulty of opening the cover body 22.

[0082] like Fig.11 , Fig.12 As shown, in some embodiments, the cover body 222 includes a top plate 2221 and a side plate 2222 connected to the top plate 2221, and the side plate 2222 protrudes downward relative to the top plate 2221, such as Fig.14 As shown in the figure (B represents the thickness of the side plate, and C represents the thickness of the top plate), the thickness of the side plate 2222 is greater than the thickness of the top plate 2221. By setting the thickness of the side plate 2222 to be greater than the thickness of the top plate 2221, the gravity of the cover body 222 is increased, and when the relative thickness is evenly set or the center of gravity moves downward when the thickness of the top plate 2221 is greater, it is beneficial for the cover body 222 to reset under the action of gravity.

[0083] like Fig.12 As shown, in some embodiments, the side plate 2222 includes a front side plate 2223, a left side plate 2224 and a right side plate 2225, and the front side plate 2223 is arranged on the side of the top plate 2221 away from the pivot axis, such as Fig.13 As shown in the figure (A indicates the thickness of the left side plate, and B indicates the thickness of the front side plate), the thickness of the front side plate 2223 is greater than the thickness of the left side plate 2224 or the right side plate 2225. By setting the thickness of the front side plate 2223 to be greater than the thickness of the left side plate 2224 or the right side plate 2225, the center of gravity of the cover body 222 is moved forward, the moment becomes larger, and the cover body 222 is easier to reset by gravity. For example, the thickness of the front side plate is greater than the left side plate 2224; or, the thickness of the front side plate 2223 is greater than the thickness of the right side plate 2225.

[0084] In some embodiments, the thickness of the side plate 2222 is greater than twice the thickness of the top plate 2221. By setting the thickness of the side plate 2222 to be greater than twice the thickness of the top plate 2221, the gravity of the cover body 222 is further increased, and the cover body 222 is further made easier to reset. For example, the thickness of the side plate 2222 is 3 times the thickness of the top plate 2221; or, the thickness of the side plate 2222 is 2.5 times the thickness of the top plate 2221. Of course, the thickness of the side plate 2222 can also be twice the thickness of the top plate 2221.

The anti-slip protrusion 241 and the matching groove 242 can be an interference connection, and there is a certain friction between the anti-slip protrusion 241 and the matching groove 242. When the sweeping device 20 vibrates, the cover body 22 cannot overcome the friction and open, but the linkage component 23 exerts a large force on the cover body 22 to overcome the friction and open the cover body 22; or, the anti-slip protrusion 241 has a certain elasticity, and the groove surface of the anti-slip groove hinders the movement of the anti-slip protrusion 241. When the sweeping device 20 vibrates, the cover body 22 cannot cause the anti-slip protrusion 241 to deform sufficiently, but the linkage component 23 exerts a large force on the cover body 22 to cause the anti-slip protrusion 241 to deform significantly, so that the cover body 22 opens.

[0086] For example, the anti-slip protrusion 241 is provided on the main body 21 , and the anti-slip groove is provided on the cover body 22 ; or, the anti-slip protrusion 241 is provided on the cover body 22 , and the anti-slip groove is provided on the main body 21 .
