[0060] In recent years, the smart home industry has flourished, and cleaning robots, with their ability to autonomously clean indoor floors, have experienced rapid development and market growth. Upgrading their functionality to meet the evolving needs of the market and users is essential for the continued development of the cleaning robot industry.

[0061] In related technologies, the mops of cleaning robot products are mainly used to mop the floor after sweeping. The functions and types of mops are relatively limited. In addition, the mops of cleaning robots need to be replaced manually by the user. They cannot be replaced automatically as needed. The need to manually remove and replace the mops each time causes a lot of inconvenience to consumers and urgently needs to be improved.

[0062] Meanwhile, the mop cloths on the product are primarily coarse-fiber cloths, suitable for mopping floors, but not ideal for cleaning up pet hair. Furthermore, with more and more families choosing to adopt pets for daily companionship, there is a greater need for cleaning up pet hair on the floor. Therefore, increasing the types of mop cloths available for the cleaning robot and enabling automatic mop cloth changing would improve the product's performance.

[0063] Based on the above concepts and problems, this invention proposes a base station 100. This base station 100 is applied to a cleaning system for replacing the cleaning component 410 of a cleaning robot 400. The base station 100 enables automatic replacement of the cleaning component 410 of the cleaning robot 400. It is understood that the cleaning robot 400 can be a sweeping robot, a mopping robot, or a combined sweeping and mopping robot. Optionally, the cleaning component 410 can be a sweeping component or a mopping component (e.g., a mop), and is not limited thereto.

[0064] In this embodiment, to facilitate the replacement of the cleaning component 410 of the cleaning robot 400, the robot body of the cleaning robot 400 and the cleaning component 410 are detachably connected. Optionally, the cleaning component 410 and the robot body can be fixed by magnetic attraction, or other structures that can achieve detachable attraction are also acceptable, and are not limited here.

[0065] The cleaning component 410 of the present invention will be described using a mopping component as an example. It should be noted that the cleaning component 410 includes a bracket and a mop cloth disposed on the bracket. The bracket includes a support plate and a mounting post protruding from the support plate. The side of the support plate facing away from the mounting post may optionally be a flat surface or an arc-shaped spherical surface, etc. The mop cloth wraps around the side of the support plate facing away from the mounting post and surrounds the periphery of the support plate, fixing it to the side of the support plate with the mounting post. It is understood that, for convenient disassembly and assembly of the mop cloth, the periphery of the side of the support plate with the mounting post is provided with hooks, buckles, or clamping structures, etc., for fixing the mop cloth. The mounting post is provided with a magnetic structure (e.g., a magnet or iron) for detachable adsorption to the robot body; this is not limited here.

[0066] Please refer to the reference. Figures 1 to 5As shown, in this embodiment of the invention, the base station 100 includes a housing 1, a lifting assembly 2, and a replacement structure 3. The housing 1 has a receiving cavity 111 with an opening 112 for accommodating a cleaning robot 400. The housing 1 also has a mounting cavity 121 and an actuating hole 113 connecting the mounting cavity 121 and the receiving cavity 111. The lifting assembly 2 is located at the bottom of the receiving cavity 111. The replacement structure 3 includes a first driving member 31 and a tray assembly 32. The first driving member 31 is located inside the mounting cavity 121, and the tray assembly... The tray assembly 32 is movably disposed within the mounting cavity 121 and connected to the first drive member 31. The tray assembly 32 is used to place the cleaning component 410. The replacement structure 3 has a first state in which the first drive member 31 drives the tray assembly 32 through the movable hole 113 and extends into the lifting assembly 2, and a second state in which the first drive member 31 drives the tray assembly 32 to be located within the mounting cavity 121. In the first state, the lifting assembly 2 drives the tray assembly 32 to rise and fall, so as to move closer to or away from the cleaning component 410 of the cleaning robot 400 in the receiving cavity 111.

[0067] In this embodiment, the housing 1 is the outer shell structure of the base station 100. The housing 1 is used to install, fix, or support components such as the lifting assembly 2 and the replacement structure 3. That is, the housing 1 provides an installation base for components such as the lifting assembly 2 and the replacement structure 3. It is understood that the housing 1 can be a shell, a box, or other structures. The housing 1 can be a metal housing structure or a non-metallic housing structure (such as plastic), and there is no limitation here.

[0068] Understandably, by providing a receiving cavity 111 with an opening 112 on the housing 1, the cleaning robot 400 can easily enter the receiving cavity 111 through the opening 112, and the receiving cavity 111 provides space for the cleaning robot 400 to be accommodated, temporarily stored, charged, replaced, or cleaned. In this embodiment, the base station 100 also includes a charging module, a control module, and other structures, which are located inside the housing 1. The control module is electrically connected to the charging module, the lifting component 2, and the replacement structure 3, and is used to control the operation of the charging module, the lifting component 2, and the replacement structure 3.

[0069] It should be noted that the charging module can be housed within the accommodating cavity 111, and can employ contact charging or non-electromagnetic charging, etc., as per existing technology, and is not limited here. Of course, the base station 100 also includes a cleaning module, a waste recycling and storage module, etc., housed in the casing 1, as per existing technology, and is not limited here.

[0070] In this embodiment, to facilitate the entry of the cleaning robot 400 into the accommodating cavity 111 from the external ground, the housing 1 of the base station 100 also includes a guide platform 13. It is understood that, as Figure 1 and Figure 6As shown, the guide platform 13 can be directly connected to the housing 1 and is provided corresponding to the opening 112. That is, the guide platform 13 and the housing 1 can be fixedly connected or integrally formed. Of course, in other embodiments, the guide platform 13 can also be connected to the housing 1 in a detachable manner and is provided corresponding to the opening 112. This allows for the disassembly, assembly, or replacement of the guide platform 13, and is not limited here.

[0071] Optionally, one side of the guide platform 13 is in contact with the ground, and the side of the guide platform 13 facing away from the ground is provided with a guide surface. The guide surface can be formed by one or more of the following: a guide ramp, a guide curved surface, and a guide arc surface, and is not limited here. In this embodiment, the distance from the guide surface to the ground is defined as the thickness of the guide platform 13. The thickness of the guide platform 13 gradually decreases from the direction of the guide platform 13 adjacent to the opening 112 to the direction away from the opening 112, and is not limited here.

[0072] In this embodiment, the housing 1 is further provided with a mounting cavity 121 and an movable hole 113 connecting the mounting cavity 121 and the accommodating cavity 111. By setting up a lifting component 2 and a replacement structure 3, the lifting component 2 is located at the bottom of the accommodating cavity 111 and a bearing groove 221 is provided in the lifting component 2. The replacement structure 3 is set up with a first driving member 31 and a tray assembly 32, such that the first driving member 31 is located in the mounting cavity 121 and the tray assembly 32 is movably located in the mounting cavity 121 and connected to the first driving member 31. The tray assembly 32 is provided with a support groove 3231 for placing the cleaning component 410. Thus, the replacement structure 3 has a first state in which the first driving member 31 drives the tray assembly 32 through the movable hole 113 and into the bearing groove 221, and a second state in which the first driving member 31 drives the tray assembly 32 to be located in the mounting cavity 121.

[0073] Understandably, when the replacement structure 3 is in the first state, the lifting component 2 drives the tray assembly 32 to rise and fall, moving closer to or further away from the cleaning component 410 of the cleaning robot 400 within the accommodating cavity 111, thereby achieving the replacement of the cleaning component 410. In this embodiment, the first driving component 31 can be a driving cylinder, a moving module, or a driving module (e.g., a driving motor coupled with a lead screw, gear, or chain, etc.), as long as the structure can drive the tray assembly 32 to move, it is acceptable and is not limited here.

[0074] In this embodiment, to facilitate the automatic replacement of the cleaning component 410 by the tray assembly 32, the replacement structure 3 further includes an adsorption component 324 disposed on the tray assembly 32 for adsorbing the cleaning component 410. Optionally, the adsorption component 324 is disposed in the support groove 3231 for adsorbing the cleaning component 410. It is understood that the adsorption component 324 may be a magnet, an electromagnetic switch, or an electromagnetic control structure. The lifting component 2 can be used to raise and lower the tray assembly 32, so that the suction component 324 of the support groove 3231 approaches and contacts the cleaning component 410 of the cleaning robot 400 in the accommodating cavity 111 for adsorption. The lifting component 2 can then be used to lower the tray assembly 32, so that the suction component 324 of the support groove 3231 adsorbs and fixes the cleaning component 410 and then detaches from the cleaning robot 400, thereby realizing the automatic removal of the cleaning component 410. Alternatively, the lifting component 2 can raise and lower the tray assembly 32, so that the support groove 3231 brings the cleaning component 410 closer to and contacts the cleaning robot 400 in the accommodating cavity 111, so that the cleaning component 410 is adsorbed and fixed to the cleaning robot 400, thereby realizing the installation of the cleaning component 410. No limitation is made here.

[0075] It should be noted that the lifting component 2 can be a tray, lifting rod, lifting cylinder, or lifting structure that performs the lifting function, etc., and is not limited here. In this embodiment, the direction in which the lifting component 2 drives the tray assembly 32 to move forms an angle with the direction in which the first driving member 31 drives the tray assembly 32 to move. Optionally, the direction in which the lifting component 2 drives the tray assembly 32 to move is perpendicular to the direction in which the first driving member 31 drives the tray assembly 32 to move.

[0076] Understandably, when the cleaning component 410 is removed, the magnetic attraction between the suction component 324 in the support groove 3231 and the cleaning component 410 should be greater than the magnetic attraction between the cleaning component 410 and the cleaning robot 400, or the magnetic attraction between the cleaning component 410 and the cleaning robot 400 should be controlled to disappear. When the cleaning component 410 is installed on the cleaning robot 400, it is sufficient to control the magnetic attraction between the suction component 324 in the support groove 3231 to disappear or the magnetic attraction between the suction component 324 and the cleaning component 410 to be less than the magnetic attraction between the cleaning component 410 and the cleaning robot 400; no specific limitation is made here.

[0077] In order to facilitate and quickly replace the cleaning parts 410 of the cleaning robot 400, in one embodiment, the housing 1 is provided with two movable holes 113, which are located on opposite sides of the accommodating cavity 111. The replacement structure 3 includes two parts, and each replacement structure 3 is provided with one movable hole 113.

[0078] Understandably, one of the two replacement structures 3 is used to remove the original cleaning component 410 from the cleaning robot 400, and the other replacement structure 3 is used to install the new cleaning component 410 onto the cleaning robot 400. The process of removing or installing the cleaning component 410 by the replacement structure 3 is as described above and is not limited here.

[0079] The base station 100 of the present invention is used to replace the cleaning part 410 of the cleaning robot 400. The base station 100 facilitates the cleaning robot 400's entry into the receiving cavity 111 through the opening 112 by configuring the housing 1 as a receiving cavity 111 with an opening 112. The receiving cavity 111 accommodates the cleaning robot 400, facilitating the replacement of the cleaning part 410 within the receiving cavity 111. Simultaneously, by providing a mounting cavity 121 and an actuating hole 113 connecting the mounting cavity 121 and the receiving cavity 111 on the housing 1, and by placing a lifting assembly 2 at the bottom of the receiving cavity 111, placing the first driving member 31 of the replacement structure 3 within the mounting cavity 121, and movably placing the tray assembly 32 of the replacement structure 3 within the mounting cavity 121 and connecting it to the first driving member 31, the tray assembly... 32 is used to place the cleaning component 410. Thus, the first driving component 31 drives the tray assembly 32 to extend into the lifting assembly 2 through the movable hole 113, so that the replacement structure 3 has a first state and the first driving component 31 drives the tray assembly 32 to be located in the mounting cavity 121, so that the replacement structure 3 has a second state. In the first state, the lifting assembly 2 drives the tray assembly 3 to rise and fall, so as to move closer to or away from the cleaning component 410 of the cleaning robot 400 in the receiving cavity 111, thereby realizing the replacement of the cleaning component 410 of the cleaning robot 400. This enables the base station 100 to realize the automatic replacement of the cleaning component 410 of the cleaning robot 400, which not only increases the types of cleaning components 410 of the cleaning robot 400, but also realizes the function of automatic replacement of cleaning components 410, thereby increasing the use scenarios and functions of the product.

[0080] It is understandable that the cleaning component 410 can be a long microfiber mop module, a coarse fiber mop module, etc., and is not limited here. The cleaning component 410 with a coarse fiber mop module is suitable for daily mopping tasks, while the cleaning component 410 with a long microfiber mop module is beneficial for cleaning hair, etc.

[0081] In one embodiment, the lifting assembly 2 includes a lifting drive 21 and a changing tray 22. The lifting drive 21 is disposed at the bottom of the accommodating cavity 111, and the changing tray 22 is movably disposed in the accommodating cavity 111 and connected to the output end of the lifting drive 21. The changing tray 22 has a bearing groove 221 on the side facing away from the lifting drive 21. In the first state, the first drive 31 drives the tray assembly 32 to extend into the bearing groove 221 through the movable hole 113, and the lifting drive 21 drives the changing tray 22 to lift and lower the tray assembly 32.

[0082] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the lifting drive component 21 of the lifting assembly 2 provides driving force to the changing plate 22. The lifting drive component 21 can be a lifting cylinder, lifting rod, lifting module or lifting drive structure (such as a motor with lead screw, gear rack or chain, etc.), which is not limited here.

[0083] Understandably, the replacement tray 22 can be a plate-shaped, disc-shaped, or pallet-like structure. A support groove 221 is provided on the side of the replacement tray 22 facing away from the lifting drive member 21, thereby using the support groove 221 to limit the placement of the pallet assembly 32. In this embodiment, the extending direction of the support groove 221 is the same as the moving direction of the pallet assembly 32. To facilitate the pallet assembly 32 passing through the movable hole 113 into the support groove 221 of the replacement tray 22, the support groove 221 of the replacement tray 22 extends through the periphery of the replacement tray 22 and is correspondingly connected to the movable hole 113.

[0084] In this embodiment, the replacement structure 3 is in the first state, and the lifting drive 21 drives the replacement disc 22 to lift the tray assembly 32, thereby making the tray assembly 32 move closer to or further away from the cleaning robot 400 located in the accommodating cavity 111.

[0085] In one embodiment, the lifting drive 21 includes a lifting motor 211 and a crank 212. The lifting motor 211 is located at the bottom of the receiving cavity 111. One end of the crank 212 is connected to the output end of the lifting motor 211, and the other end of the crank 212 is provided with a first slider 213. The first slider 213 is movably connected to the side of the changing disc 22 facing away from the bearing groove 221. In the first state, the lifting motor 211 drives the crank 212 to rotate, so that the first slider 213 slides relative to the changing disc 22, thereby pushing the changing disc 22 up and down.

[0086] In this embodiment, as Figure 2 and Figure 4 As shown, by setting the lifting drive 21 to a structure of lifting motor 211 cooperating with crank 212, the lifting motor 211 drives the crank 212 to rotate, so that the crank 212 drives the first slider 213 to slide relative to the changing plate 22, thereby pushing the changing plate 22 to rise and fall. In other words, the action of lifting motor 211 driving crank 212 to rotate is converted into the movement of changing plate 22 rising and falling.

[0087] Understandably, the other end of the crank 212 is provided with a first slider 213, which is movably connected to the side of the changing disc 22 facing away from the bearing groove 221. In this embodiment, the crank 212 and the first slider 213 can be rotatably connected. Optionally, the first slider 213 can be a cylindrical structure.

[0088] In this embodiment, the lifting motor 211 drives the crank 212 to rotate in the forward direction, causing the first slider 213 to push the replacement disc 22 to rise; the lifting motor 211 drives the crank 212 to rotate in the reverse direction, causing the first slider 213 to drive the replacement disc 22 to fall, which is not limited here.

[0089] In one embodiment, such as Figure 2 and Figure 4 As shown, the replacement disc 22 may optionally have a first sliding groove 222 on the side facing away from the bearing groove 221. Optionally, the extending direction of the first sliding groove 222 is perpendicular to the lifting direction of the replacement disc 22. In this embodiment, in the first state, the replacement structure 3 has the first slider 213 sliding limited within the first sliding groove 222.

[0090] In order to achieve vertical lifting and lowering of the replacement disc 22, in one embodiment, one of the replacement disc 22 and the cavity wall of the receiving cavity 111 is provided with a guide member, and the other is provided with a sliding guide member, and the sliding guide member is slidably connected to the guide member.

[0091] It is understood that the guide and the guide slide can be a matching structure of guide post and guide hole, a matching structure of guide rail and guide groove, or other structures that can achieve guidance, and are not limited here. In this embodiment, the cavity wall of the receiving cavity 111 is provided with a guide, and the changing disk 22 is provided with a guide slide. The changing disk 22 achieves movable connection with the cavity wall of the receiving cavity 111 through the sliding engagement of the guide slide and the guide, and is not limited here.

[0092] To further enhance the lifting driving force of the changing disc 22, optionally, two lifting drive components 21 are included. The two lifting drive components 21 are spaced apart at the bottom of the receiving cavity 111 and are respectively connected to the changing disc 22. In this embodiment, the two lifting drive components 21 move synchronously to realize the lifting and lowering of the changing disc 22, thereby realizing the removal and installation of the cleaning component 410 of the cleaning robot 400.

[0093] In one embodiment, the tray assembly 32 includes a slider 321, a connecting rod 322, and a tray 323. The slider 321 is movably disposed within the mounting cavity 121 and connected to the first drive member 31. One end of the connecting rod 322 is rotatably connected to the slider 321, and the tray 323 is rotatably connected to the other end of the connecting rod 322. The tray 323 is provided with a support groove 3231. In a first state, the first drive member 31 drives the slider 321 to slide the connecting rod 322 and the tray 323, so that the tray 323 passes through the movable hole 113 and extends into the lifting assembly 2. In a second state, the first drive member 31 drives the slider 321 to slide the connecting rod 322 and the tray 323, so that the tray 323 disengages from the lifting assembly 2 and retracts into the mounting cavity 121.

[0094] In this embodiment, as Figure 2 and Figure 5 As shown, by configuring the tray assembly 32 as a slider 321, a connecting rod 322, and a tray 323, the connecting rod 322 connects the slider 321 and the tray 323, so that the two ends of the connecting rod 322 are rotatably connected to the slider 321 and the tray 323 respectively. Thus, when the replacement structure 3 is in the first state, the first drive member 31 drives the slider 321 to slide the connecting rod 322 and the tray 323, so that the tray 323 passes through the movable hole 113 and extends into the bearing groove 221. The lifting component 2 drives the tray 323 of the tray assembly 32 to rise and fall, so as to move closer to or away from the cleaning component 410 of the cleaning robot 400 in the accommodating cavity 111. At this time, the replacement disc 22 of the lifting component 2 drives the tray 323 to rise and fall, and because of the setting of the connecting rod 322, it is not affected by the slider 321.

[0095] It is understandable that the sliding member 321 and the connecting rod 322 can be rotatably connected by a hole and shaft. For example, one of the sliding member 321 and the connecting rod 322 may have a connecting lug, and the other may have a rotating shaft. The sliding member 321 is rotatably connected to the connecting rod 322 through the connecting lug and the rotating shaft hole. This is not limited here. Of course, the pallet member 323 and the connecting rod 322 can also be rotatably connected by a hole and shaft. For example, one of the pallet member 323 and the connecting rod 322 may have a connecting lug, and the other may have a rotating shaft. The pallet member 323 is rotatably connected to the connecting rod 322 through the connecting lug and the rotating shaft hole. This is not limited here.

[0096] Optionally, the pallet component 323 may be a plate-shaped, tray-shaped, or disc-shaped structure, and no limitation is made here. By providing a support groove 3231 in the pallet component 323, the cleaning component 410 is placed, positioned, and limited by the support groove 3231, thereby preventing the cleaning component 410 from shifting.

[0097] In this embodiment, when the replacement disc 22 of the lifting assembly 2 moves the tray component 323 up and down, the connecting rod 322 can synchronously move the tray component 323 upward, thereby completing the installation or removal of the cleaning component 410 of the cleaning robot 400. The first driving component 31 drives the sliding component 321 to slide the connecting rod 322 and the tray component 323, thereby realizing the overall left and right movement of the tray assembly 32.

[0098] In one embodiment, the pallet component 323 has a limiting block 3232 on the side facing away from the support groove 3231, and the lifting component 2 has a bearing groove 221. In a first state, the limiting block 3232 is slidably limited within the bearing groove 221. It is understood that... Figure 5As shown, by setting a limiting block 3232 on the pallet component 323, the pallet component 323 is slidably limited within the bearing groove 221 by the limiting block 3232, so as to prevent the pallet component 323 from shifting when the lifting component 2 drives the pallet component 323 of the pallet component 32 to rise and fall.

[0099] Optionally, one of the sidewalls of the bearing groove 221 and the sidewall of the limiting block 3232 is provided with a limiting inclined surface 223, and the other is provided with a mating inclined surface 3233, wherein the mating inclined surface 3233 slides in engagement with the limiting inclined surface 223. In this embodiment, as shown... Figure 4 and Figure 5 As shown, when the pallet component 323 extends into the bearing groove 221 through the movable hole 113, the limiting block 3232 moves along the bearing groove 221. At this time, the mating inclined surface 3233 slides into the limiting inclined surface 223 to limit the movement.

[0100] Understandably, the limiting block 3232 and the bearing groove 221 may have a dovetail protrusion and dovetail groove matching structure, a T-shaped protrusion and T-shaped groove matching structure, etc., which are not limited here. Optionally, the distance between the two side walls of the bearing groove 221 gradually decreases from the bottom wall of the bearing groove 221 to the groove opening of the bearing groove 221.

[0101] In one embodiment, such as Figure 5 As shown, the side wall of the pallet component 323 is also provided with a limiting platform 3234, which supports and abuts against the end face of the groove of the bearing groove 221. It can be understood that by setting the limiting platform 3234 around the periphery of the pallet component 323, the cooperation between the limiting platform 3234 and the limiting block 3232 can achieve both sliding limitation of the pallet component 323 and the bearing groove 221, and also provide sliding guidance by supporting and abutting against the end face of the groove of the bearing groove 221.

[0102] In one embodiment, the first driving member 31 includes a driving motor 311 and a driving rod 312. The driving motor 311 is disposed in the mounting cavity 121, and the driving rod 312 is disposed in the mounting cavity 121. One end of the driving rod 312 is connected to the output end of the driving motor 311, and the other end of the driving rod 312 is provided with a second slider 313. The second slider 313 is movably connected to the sliding member 321. The driving motor 311 drives the driving rod 312 to rotate, so that the second slider 313 slides relative to the sliding member 321, thereby pushing the sliding member 321 to drive the connecting rod 322 and the tray member 323 to slide.

[0103] In this embodiment, as Figure 2 and Figure 5As shown, by setting the first driving member 31 as a cooperating structure of the driving motor 311 and the driving rod 312, and providing a second slider 313 at the other end of the driving rod 312, the second slider 313 is movably connected to the sliding member 321. Thus, when the driving motor 311 drives the driving rod 312 to rotate, the second slider 313 slides relative to the sliding member 321, pushing the sliding member 321 to drive the connecting rod 322 and the tray member 323 to slide. In other words, the rotational motion of the driving motor 311 driving the driving rod 312 is converted into the sliding motion of the second slider 313 pushing the sliding member 321 to drive the connecting rod 322 and the tray member 323 to slide.

[0104] Understandably, the drive motor 311 of the first drive component 31 provides driving force to the drive rod 312. The drive rod 312 and the second slider 313 can be rotatably connected. Optionally, the second slider 313 can be cylindrical, square, or other structures, and is not limited here.

[0105] In this embodiment, the drive motor 311 drives the drive rod 312 to rotate in the forward direction, so that the second slider 313 pushes the slider 321 to drive the connecting rod 322 and the tray 323 forward; the drive motor 311 drives the drive rod 312 to rotate in the reverse direction, so that the second slider 313 pulls the slider 321 to drive the connecting rod 322 and the tray 323 backward, which is not limited here.

[0106] In one embodiment, the slider 321 includes a sliding portion 3211 and a connecting portion 3212 arranged at an angle. The sliding portion 3211 is rotatably connected to the connecting rod 322 and slidably connected to the cavity wall in the mounting cavity 121. The connecting portion 3212 is provided with a second sliding groove 3213. The extending direction of the second sliding groove 3213 is perpendicular to the sliding direction of the slider 321. The second slider 313 is limited to sliding within the second sliding groove 3213.

[0107] In this embodiment, as Figure 2 and Figure 5 As shown, by configuring the slider 321 as a sliding part 3211 and a connecting part 3212 arranged at an angle, the sliding part 3211 is slidably connected to the cavity wall inside the mounting cavity 121, thereby limiting the movement direction of the connecting rod 322 and the tray 323 driven by the sliding part 3211. By providing a second groove 3213 in the connecting part 3212, the extension direction of the second groove 3213 is perpendicular to the sliding direction of the slider 321, and the second slider 313 is slidably limited within the second groove 3213. Thus, when the drive motor 311 drives the drive rod 312 to rotate, the second slider 313 slides relative to the slider 321, thereby pushing the slider 321 and driving the connecting rod 322 and the tray 323 to slide.

[0108] Optionally, the second groove 3213 extends in a vertical direction, and the sliding member 321 slides in a horizontal direction.

[0109] In one embodiment, the first driving member 31 further includes an elastic member 314, one end of which is connected to the side of the sliding part 3211 away from the connecting rod 322, and the other end of which is connected to the cavity wall of the mounting cavity 121.

[0110] In this embodiment, as Figure 2 As shown, by providing an elastic element 314, the sliding element 314 provides cushioning and a restoring force for the sliding of the sliding element 321. It is understood that the elastic element 314 can be a telescopic spring or a return spring, etc., and is not limited here.

[0111] In one embodiment, a sliding plate 122 is provided in the mounting cavity 121. The sliding plate 122 is provided with a sliding hole 123. The connecting part 3212 is movably inserted through the sliding hole 123 and slides with the second slider 313. The sliding part 3211 slides against the sliding plate 122.

[0112] In this embodiment, as Figure 2 and Figure 3 As shown, by providing a sliding plate 122 within the mounting cavity 121, and by providing a sliding hole 123 within the sliding plate 122, the sliding hole 123 provides clearance and guidance for the connecting portion 3212 of the sliding member 321. It can be understood that the connecting portion 3212 movably passes through the sliding hole 123 and slides in cooperation with the second slider 313, while the sliding portion 3211 slides against the sliding plate 122.

[0113] Understandably, the slide plate 122 is provided with a limiting groove, and the sliding part 3211 is slidably limited within the limiting groove of the slide plate 122, with the sliding hole 123 passing through the bottom wall of the limiting groove. Optionally, the extending direction of the limiting groove is the same as the extending direction of the sliding hole 123. In this embodiment, the limiting groove of the slide plate 122 passes through one end edge of the slide plate 122 and is correspondingly connected to the movable hole 113.

[0114] In one embodiment, the housing 1 includes a first outer shell 11 and at least one second outer shell 12. The first outer shell 11 is provided with a receiving cavity 111. The bottom wall of the receiving cavity 111 is provided with a mounting groove 114. The lifting component 2 is disposed in the mounting groove 114. The side wall of the first outer shell 11 is also provided with at least one movable hole 113. The second outer shell 12 is connected to the first outer shell 11 and is provided corresponding to the movable hole 113. The second outer shell 12 is provided with a mounting cavity 121 communicating with the movable hole 113.

[0115] In this embodiment, as Figures 1 to 3As shown, the first outer shell 11 and at least one second outer shell 12 of the housing 1 can be an integrally formed structure. Of course, in other embodiments, the first outer shell 11 and at least one second outer shell 12 can also be configured as separate structures, which can be connected to the first outer shell 11 as needed, and are not limited here.

[0116] Understandably, to facilitate the installation of the lifting component 2, the bottom wall of the accommodating cavity 111 is provided with a mounting groove 114, and the lifting component 2 is disposed within the mounting groove 114. In this embodiment, the mounting groove 114 corresponds to the cleaning component 410 of the cleaning robot 400, that is, after the cleaning robot 400 enters the accommodating cavity 111 through the guide platform 13 from the opening 112, the cleaning robot 400 will not be affected by the mounting groove 114. It should be noted that the bottom wall of the accommodating cavity 111 also forms a support platform for supporting the cleaning robot 400, which is arranged around the mounting groove 114, and is not limited here.

[0117] In this embodiment, the first outer shell 11 has an opening 112 on the side corresponding to the guide platform 13, and the side walls of the first outer shell 11 on both sides of the guide platform 13 are respectively provided with movable holes 113. Optionally, there are two second outer shells 12, which are symmetrically arranged on both sides of the first outer shell 11 and located on both sides of the opening 112.

[0118] Understandably, the second outer shell 12 is connected to the first outer shell 11 and is provided with a corresponding movable hole 113. The second outer shell 12 is provided with a mounting cavity 121 that communicates with the movable hole 113, so the mounting cavity 121 is used to install and fix the replacement structure 3.

[0119] Optionally, the tray assembly 32 of the replacement structure 3 is provided with two support slots 3231 for placing the cleaning item 410. In this embodiment, as... Figure 2 and Figure 5 As shown, the pallet component 323 is provided with two support grooves 3231. The two support grooves 3231 are arranged adjacently, or they can be connected, which is not limited here.

[0120] like Figure 6 As shown, the present invention also proposes a cleaning system 500, which includes the base station 100 and the cleaning robot 400 described above. The specific structure of the base station 100 is as described in the foregoing embodiments. Since the cleaning system 500 adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be described in detail here.

[0121] In this embodiment, the cleaning robot 400 is provided with a detachable cleaning component 410. It is understood that the cleaning robot 400 also includes a robot body, which is detachably connected to the cleaning component 410. Optionally, the robot body and the cleaning component 410 are detachably connected using a magnetic attraction method.

[0122] Understandably, the cleaning system 500 has a replacement state in which the cleaning robot 400 is located in the accommodating cavity 111 of the base station 100; in the replacement state, the lifting component 2 of the base station 100 drives the tray component 32 to rise and fall to replace the cleaning component 410 of the cleaning robot 400.

[0123] In this embodiment, the cleaning robot 400 has a mopping mode and a sweeping mode. When the cleaning robot 400 is in mopping mode, the cleaning component 410 is a thick fiber mop module. At this time, the cleaning robot 400 moves into the accommodating cavity 111 of the base station 100. The first driving component 31 of the replacement structure 3 drives the tray assembly 32 to extend into the bearing groove 221 through the movable hole 113, and the lifting component 2 drives the tray assembly 32 to rise and fall, so as to move closer to or away from the cleaning robot 400 in the accommodating cavity 111. At this time, the cleaning component 410 is placed in the tray component 323 of the tray assembly 32, and the installation action of the cleaning component 410 is realized by the suction component 324 of the tray assembly 32. After the cleaning component 410 is installed, the lifting component 2 drives the tray assembly 32 to fall and move away from the cleaning robot 400, the replacement structure 3 resets, the cleaning robot 400 leaves the base station 100, and begins mopping.

[0124] When the cleaning robot 400 is in cleaning mode, the cleaning component 410 needs to be replaced. The cleaning component 410 is a long, fine fiber mop module. At this time, the cleaning robot 400 moves into the receiving cavity 111 of the base station 100. The first drive component 31 of the replacement structure 3 drives the tray assembly 32 through the movable hole 113 into the carrying groove 221, and the lifting component 2 drives the tray assembly 32 to rise and fall, moving it closer to or away from the cleaning robot 400 in the receiving cavity 111. At this time, the cleaning component 410 is not placed in the tray component 323 of the tray assembly 32. The cleaning component 410 is removed by the suction component 324 of the tray assembly 32. Then, the lifting component 2 drives the tray assembly 32 to descend and move away from the cleaning robot 400. The replacement structure 3 resets, and another replacement... The first drive component 31 of the replacement structure 3 drives the tray assembly 32 to extend into the bearing groove 221 through the movable hole 113, and the lifting component 2 drives the tray assembly 32 to rise and fall, so as to approach or move away from the cleaning robot 400 in the accommodating cavity 111. At this time, the cleaning component 410 (long fine fiber mop module) is placed in the tray component 323 of the tray assembly 32. The cleaning component 410 is installed through the suction component 324 of the tray assembly 32. Then, the lifting component 2 drives the tray assembly 32 to fall and move away from the cleaning robot 400. The replacement structure 3 is reset, the cleaning robot 400 leaves the base station 100 and begins cleaning work.

[0125] The above actions enable the cleaning robot 400 to have different types of cleaning parts 410 to better complete different cleaning tasks, and also enable automatic replacement of the mop.

[0126] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention.
