Description

Technical Field

[0001] This application relates to the field of cleaning machinery technology, and in particular to base stations and cleaning systems. Background Technology

[0002] Cleaning robots, such as sweeping and mopping robots, have a mop tray on their bottom with a mop on it. The robot cleans the floor using the mop while moving. After working for a certain period, or after detecting dirt on the mop, or after completing the cleaning task, the robot returns to the base station. The robot can dock at the base station to perform self-cleaning, cleaning the mop.

[0003] The base station is equipped with a cleaning tank. Wastewater from cleaning cloths enters the tank, and although it is discharged through the drain pipe, some residue remains at the bottom. The cleaning tank requires regular manual cleaning. While some models on the market can automatically clean the tank, these require complex transmission structures or additional drive motors, resulting in complex structures and high manufacturing and assembly costs. Summary of the Invention

[0004] In view of the above problems, embodiments of this application are proposed. One object of the embodiments of this application is to provide a base station with a simple structure that can self-clean the cleaning tank without the need for motor drive.

[0005] In a first embodiment of this application, a base station is provided. The base station has a docking station for a cleaning robot; the base station includes:

[0006] A cleaning tank is installed at the docking position;

[0007] A first cleaning structure is disposed in the cleaning tank for cleaning the cleaning actuators on the cleaning robot. A hollow area is provided between the first cleaning structure and the inner wall of the cleaning tank, and the hollow area is disposed on the movement path of the cleaning actuators.

[0008] The second cleaning structure is movably disposed within the cleaning tank. The second cleaning structure is used to clean the cleaning tank. The second cleaning structure has a cleaning component and a contact portion, at least a portion of the contact portion being located in the hollow area.

[0009] When the cleaning actuator moves, the contact portion located in the hollow area is driven by the cleaning actuator to drive the cleaning component to clean the cleaning tank.

[0010] In a second embodiment of this application, a cleaning system is provided. This cleaning system includes a cleaning robot and a base station as described in the above embodiments. The cleaning robot has a cleaning actuator that can move relative to the robot's body to clean the area to be cleaned. The base station can clean the cleaning actuator and, simultaneously, can self-clean its own cleaning tank under the influence of the cleaning actuator.

[0011] In a third embodiment of this application, a cleaning system is provided, including a cleaning robot and a base station. The cleaning robot has cleaning actuators, and the base station has a docking position for docking the cleaning robot. The base station includes a cleaning tank disposed at the docking position.

[0012] A first cleaning structure is disposed within the cleaning tank and is used to clean the cleaning actuator; and

[0013] The second cleaning structure is movably disposed within the cleaning tank and is used to clean the cleaning tank.

[0014] The cleaning robot is docked at the docking position, with a portion of the cleaning actuator in contact with the first cleaning structure and another portion of the cleaning actuator in contact with the second cleaning structure.

[0015] When the cleaning actuator rotates, the first cleaning structure cleans the cleaning actuator and forms a first area for cleaning the cleaning actuator. The second cleaning structure is driven by the cleaning actuator to clean the cleaning tank and forms a second area for moving the second cleaning structure.

[0016] The technical solution provided in this application embodiment utilizes the cleaning actuator that moves during self-cleaning, and the second cleaning structure in the cleaning tank of the base station moves, so that while cleaning the cleaning actuator of the cleaning robot, it can also clean its own cleaning tank. There is no need to add a complex transmission structure and drive motor. The structure is simple, easy to implement, and low in cost. Attached Figure Description

[0047] The inventors of this application have discovered that most existing base stations require manual cleaning of the cleaning tank. Users need to disassemble the cleaning tank, manually scrub it, and then reassemble it. If the cleaning tank is not cleaned in a timely manner, bacteria will grow, causing mold and foul odors.

[0048] The reason for this is that the base station lacks a scraping structure capable of cleaning the cleaning tank. Based on this, the inventors attempted to install a tank cleaning structure that could abut against the inner wall of the cleaning tank. However, to allow this tank cleaning structure to move and scrape the inner wall, a power component and transmission structure also need to be installed on the base station. While this method can effectively scrape off stubborn dirt adhering to the inner wall of the cleaning tank, achieving a good cleaning effect, the addition of a power component and transmission structure not only makes the structure complex and costly but also occupies limited space within the base station, resulting in a larger base station size.

[0049] To address the aforementioned problems, the inventors of this application considered a method that, without adding power components or complex transmission structures, could both clean the cleaning actuators of the cleaning robot and utilize the movement of these actuators to scrape the inner walls (including side walls and bottom walls) of the cleaning tank. Therefore, the following embodiments of this application are proposed. Since the cleaning actuators (such as a cloth disc or roller brush) of the cleaning robot move (e.g., rotate or turn) when the cleaning robot initiates self-cleaning at the base station, the inventors conceived of using the moving cleaning actuators to drive the movement of the base station's tank cleaning structure. For example, if the cleaning actuator is a cloth disc, during self-cleaning, the cloth disc rotates. During a full rotation, the cloth disc cleans the cloth on the disc during the first half-rotation, and during the second half-rotation, the rotation of the cloth disc drives the cleaning of the base station's tank.

It should be understood that the specific embodiments described herein are merely for explaining this application and not for limiting this application. It should also be noted that, for ease of description, only the parts related to this application are shown in the drawings, not all structures.

Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.

[0051] This embodiment provides a base station with a docking position for a cleaning robot. The base station includes a cleaning tank, a first cleaning structure, and a second cleaning structure. The cleaning tank is disposed at the docking position. The first cleaning structure is disposed within the cleaning tank and is used to clean the cleaning actuators on the cleaning robot. A hollow area is provided between the first cleaning structure and the inner wall of the cleaning tank, and the hollow area is located on the movement path of the cleaning actuators. The second cleaning structure is movably disposed within the cleaning tank and is used to clean the cleaning tank. The second cleaning structure has a cleaning component and a contact portion, at least part of which is located in the hollow area. When the cleaning actuators move, the contact portion located in the hollow area is driven by the cleaning actuators to drive the cleaning component to clean the cleaning tank. Therefore, the cleaning tank can be cleaned without additional drive and transmission mechanisms. Thus, the technical solution provided by this embodiment does not require additional drive motors and transmission structures, is simple in structure, easy to implement, and low in cost.

[0052] Specifically, such as Figures 1-2 As shown, the base station has a docking position for a cleaning robot, and a cleaning tank for accommodating the cleaning actuator 2 of the cleaning robot is provided at the docking position. The base station also includes a first cleaning structure 20 and a second cleaning structure 10. The first cleaning structure 20 is disposed in the cleaning tank and is used to clean the cleaning actuator 2 on the cleaning robot. A hollow area 23 is provided between the first cleaning structure 20 and the inner wall of the cleaning tank. The second cleaning structure 10 is movably disposed in the cleaning tank and located below the first cleaning structure 20. The second cleaning structure 10 is used to clean the cleaning tank. The second cleaning structure 10 has a cleaning element 16 and a contact portion. During self-cleaning, the cleaning actuator 2 moves relative to the first cleaning structure 20. The contact portion contacts the cleaning actuator through the hollow area 23. On the one hand, the first cleaning structure 20 can scrape the dirt on the cleaning actuator 2. On the other hand, the contact portion contacts the cleaning actuator 2. The second cleaning structure 10 is driven by the cleaning actuator 2 to move, and the cleaning element 16 cleans the cleaning tank. Specifically, the movement of the cleaning actuator 2 can be rotation. In addition to moving with the cleaning robot to clean the surface to be cleaned, the cleaning actuator 2 can also increase the friction of the surface to be cleaned by its own rotation, thereby effectively removing dirt from the surface to be cleaned.

[0053] In some embodiments of this application, one possible structure of the cleaning actuator 2 is as follows: it includes a first part and a second part connected in sequence, wherein the first part is located on the inner periphery of the cleaning actuator, the second part is located on the outer periphery of the cleaning actuator, and the second part abuts against the contact part through a hollow area. When the cleaning actuator 2 rotates, the frictional force applied by the second part to the contact part causes the contact part to rotate with the cleaning actuator 2, thereby causing the second cleaning structure 10 as a whole to be driven by the cleaning actuator 2 to generate movement.

[0054] It is understandable that the second part cannot be cleaned by the first cleaning structure 20 when it comes into contact with the contact portion. Therefore, the smaller the area of ​​the second part that comes into contact with the contact portion, the better. However, the smaller the area of ​​the second part, the less frictional force the cleaning actuator 2 applies to the rotation of the second cleaning structure 10. Therefore, the area of ​​the second part cannot be too small. Thus, in some embodiments of this application, the length ratio of the first part to the second part is greater than or equal to 4:1 and less than or equal to 8:1, which not only ensures that the second part can be thoroughly cleaned, but also guarantees that the second cleaning structure has sufficient driving force for rotation.

[0055] like Figure 2As shown, one possible structure for the cleaning actuator 2 is a wiping tray. When the wiping tray is in the cleaning tank, it abuts against the first cleaning structure 20. As the wiping tray rotates, the wiping tray and the first cleaning structure 20 continuously rub and squeeze, dissolving the dirt adhering to the wiping tray into the cleaning water, turning it into wastewater, which is then carried away from the wiping tray. Simultaneously, the wiping tray abuts against the contact part, and initially, the rotation of the wiping tray causes relative movement with the second cleaning structure 10, generating friction between them. Since the second cleaning structure 10 can move relative to the cleaning tank, it can rotate relative to the cleaning tank, thus rotating relative to the cleaning tank under the influence of friction. The cleaning component 16 can be configured to abut against the tank wall (including the side walls and bottom wall), thereby scraping the tank wall with the cleaning component 16 during the rotation of the second cleaning structure 10 relative to the cleaning tank. The cleaning component 16 can scrape off the dirt adhering to the inner wall of the cleaning tank, dissolving it into the wastewater, which is then carried away from the cleaning tank. Understandably, to prevent centrifugal force during rotation, the mop tray is typically a disc. However, to better accommodate the mop tray and minimize the size of the cleaning tank, allowing more space on the base station to accommodate other components, the cleaning tank is cylindrical. Furthermore, the path traversed by the cleaning component 16 during rotation of the second cleaning structure is also circular, thus the cylindrical cleaning tank also achieves good cleaning results. The base station can be, but is not limited to, a floor scrubber base station, a sweeping robot base station, a mopping robot base station, or a window cleaning robot base station, etc.

[0056] like Figures 1-2As shown, to facilitate the movement of the cleaning robot to the docking position, the base station is typically equipped with a ramp 3 for the cleaning robot to climb. To keep the base station compact and minimize space usage, the portion of the base station that can accommodate the cleaning robot usually only covers the cleaning actuator 2 of the robot, allowing for easy cleaning of the actuator 2. The remaining portion of the cleaning robot is located on the ramp 3. Therefore, when the cleaning robot is at the docking position, the plane of the actuator is parallel to the ramp 3. To better facilitate the contact between the first cleaning structure 20 and the cleaning actuator 2, enabling self-cleaning of the actuator 2 and ensuring cleaning effectiveness, in this embodiment, the upper surface of the first cleaning structure 20 is an angled cleaning component. The plane of the cleaning component can be parallel to the ramp 3, allowing the cleaning actuator 2 to fully contact the first cleaning structure 20 when it is in the cleaning tank, achieving thorough rubbing of the cleaning actuator 2 during self-cleaning. Meanwhile, to facilitate the entry of the cleaning actuator 2, the plane of the cleaning tank opening is also inclined. The docking position has an entrance for the cleaning robot to enter. The entrance side of the docking position is the front side, and the side opposite the entrance side is the rear side. The opening of the cleaning tank is lower in the front and higher in the back, meaning that the inclination direction of the cleaning tank opening is the same as the inclination direction of the first cleaning structure. To achieve better cleaning of the bottom wall of the cleaning tank, the second cleaning structure 10 is parallel to the bottom wall of the cleaning tank, so that the plane of the contact part intersects with the plane of the upper surface of the first cleaning structure 20, allowing the contact part to contact the cleaning actuator 2 through the hollow area 23. Further, as... Figures 2-5 , Figure 7 as well as Figure 11 As shown, the first cleaning structure includes multiple scrapers 22 set at the opening of the tank. During the rotation of the cleaning actuator 2, the scrapers 22 are continuously contacted, which not only allows for thorough rubbing, but the gap between two adjacent scrapers 22 also facilitates the flow of sewage on the cleaning actuator 2 into the cleaning tank.

[0057] Since the second cleaning structure 10 is located below the first cleaning structure 20, and the upper surface of the first cleaning structure 20 is an inclined surface, as... Figure 3 , Figure 4 , Figure 7 As shown, in order to avoid interference between the first cleaning structure 20 and the second cleaning structure 10, there is no scraping rib 22 at the bottom of the groove or the scraping rib 22 provided at the bottom of the groove is broken to form a hollow area 23.

[0058] In some other embodiments of this application, the base station can fully accommodate the cleaning robot. At this time, the cleaning actuator 2 on the cleaning robot is in a horizontal state. In order to ensure a good cleaning effect on the cleaning actuator 2, the upper surface of the first cleaning structure 20 is in a horizontal state, while the upper surface of the second cleaning structure 10 is inclined. The upper surface of the second cleaning structure 10 gradually tilts downward along the direction in which the cleaning robot enters the base station, so that when the contact part rotates to the hollow area, it is higher than other parts of the second cleaning structure and can fully abut against the second part of the cleaning actuator 2.

[0059] To ensure a more thorough cleaning, the cleaning actuator 2 applies pressure to the first cleaning structure, increasing friction and thus enhancing the rubbing effect. To prevent the first cleaning structure 20 from being crushed by the pressure applied by the cleaning actuator 2, the scraper 22 needs to have sufficient strength. In some embodiments of this application, such as... Figures 2-5 , Figure 7 as well as Figure 11 As shown, one possible structure for the scraper 22 is as follows: Figure 3 , Figure 5 , Figure 7 As shown, the scraper 22 includes a connecting plate 221 and vertical ribs 222. The connecting plate 221 has multiple kneading protrusions spaced at its center, and vertical ribs 222 are provided on both sides of the connecting plate 221. The vertical ribs 222 are at the same height as the kneading protrusions and both abut against the cleaning actuator 2. Both the vertical ribs 222 and the protrusions increase the strength of the connecting plate 221, making the scraper 22 stronger overall and preventing it from being crushed during the self-cleaning process of the cleaning actuator 2. Furthermore, during the cleaning of the cleaning actuator 2, the vertical ribs 222 scrape off the liquid on the cleaning actuator 2, and the scraped liquid falls into the connecting plate 221 and the cleaning tank. The multiple kneading protrusions on the connecting plate 221 are used to scrape off impurities (such as hair, particles, etc.) on the cleaning actuator 2.

[0060] Furthermore, the length of the vertical rib 222 is greater than or equal to the radius of the cleaning actuator 2, so the vertical rib 222 can fully abut against the cloth on the cleaning actuator 2 during its rotation. Along the direction of rotation of the cleaning actuator 2, the first vertical rib 2222 that abuts against the cleaning actuator 2 has a length less than the length of the connecting plate 221, and the second vertical rib 2222 has a length equal to the length of the connecting plate 221. This results in the second vertical rib 2222 having the same edge length as the connecting plate 221, while the first vertical rib 2221 has a different edge length than the connecting plate 221, creating a gap at both ends of the first vertical rib 2221, allowing wastewater remaining on the connecting plate 221 to flow into the cleaning tank through the gap. When the cleaning actuator 2 passes the first vertical rib 2221, the first vertical rib 2221, together with the kneading protrusion, kneads the cleaning actuator 2. Under the action of friction, the dirt adhering to the cleaning actuator 2 is rubbed off or floated up. The cleaning actuator 2 rotates and abuts against the second vertical rib 2222. At this time, the second vertical rib 2222 can squeeze the cleaning actuator 2, pressing out the sewage adsorbed in the cleaning actuator 2. The impurities kneaded by the kneading protrusion fall into the connecting plate 221 and the cleaning tank. The impurities falling on the connecting plate 221 can flow into the cleaning tank from the gaps under the action of sewage. The above process is repeated continuously during the rotation of the cleaning actuator 2. Of course, during this process, the cleaning actuator 2 will also be repeatedly wetted by cleaning water, so that the relatively dry cloth squeezed by the scraper rib 22 absorbs cleaning water. When the cloth full of cleaning water passes the scraper rib 22 again, it continues to scrape off the dirt adhering to the cloth, so as to achieve a good cleaning effect on the cleaning actuator 2. In some embodiments of this application, the end of the connecting plate 221 facing the wall of the cleaning tank is provided with a through drain hole 224, and / or the connecting plate 221 is provided with a plurality of drain holes 224 at intervals on the side of the first vertical rib 2221 or the second vertical rib 2222. This not only prevents sewage from staying on the scraper 22 and prevents sewage from adhering to the cleaning actuator 2 again and affecting the cleaning effect on the cleaning actuator 2, but also allows sewage to be discharged from the scraper 22 into the cleaning tank as soon as possible.

[0061] See Figure 3 As shown, the cleaning actuator 2 consists of two cloth trays. During cleaning, the cloth tray on the left... Figure 3 Rotate clockwise as indicated by the middle arrow, and the cloth tray on the right side will... Figure 3The middle arrow indicates counter-clockwise rotation. As shown in the diagram, on the left side, rotating clockwise, the cloth disc first scrapes water via the second vertical rib 2222, then scrapes away impurities via multiple rubbing protrusions. The scraped-off wastewater and impurities can enter the washing tank through the gaps. Similarly, on the right side, rotating counter-clockwise, the cloth disc first scrapes water via the second vertical rib 2222, then scrapes away impurities via multiple rubbing protrusions. The scraped-off wastewater and impurities can enter the washing tank through the gaps.

[0062] from Figure 3 and Figure 5 It can also be seen that the multiple scraping ribs 22 include vertical ribs 222 that traverse the cleaning tank. The vertical ribs 222 that traverse the cleaning tank include: a middle portion located between two support columns 21, and two side portions located on the outside of the two support columns respectively.

[0063] In order to ensure that the scraper 22 has sufficient strength to resist pressure, in the embodiments of this application, such as Figures 2-7 , Figure 12 As shown, the base station also includes a scraping seat 40, which has a vertical wall 41 and a mounting groove at its docking position. The scraping seat 40 is detachably installed in the mounting groove, and the vertical wall 41 and the bottom of the mounting groove form a cleaning groove. The first cleaning structure 20 also includes a support column 21, which is located in the center of the first cleaning structure 20. The support column 21 is detachably sleeved on the bottom wall of the cleaning groove by a snap fastener, so that the scraping seat 40 can be detachably installed on the bottom wall of the mounting groove. When the scraping seat 40 is removed from the bottom wall of the mounting groove, the first cleaning structure 20, the second cleaning structure 10, and the base station can be separated. After the scraping seat 40 is removed from the base station, it can be sprayed from top to bottom with a spray nozzle to deeply clean the first and second cleaning structures. No water will remain during the spraying process, and it is easy to scrub with a brush.

[0064] Furthermore, such as Figure 6 As shown, in some embodiments of this application, in order to facilitate the installation of the scraping seat 40, the scraping seat 40 is provided with a plurality of positioning posts (not shown in the figure) on the circumferential direction of the side facing the mounting groove. Correspondingly, the groove wall of the mounting groove is provided with a plurality of positioning grooves. The positioning posts match the positioning grooves. When the scraping seat 40 connected to the first cleaning structure 20 is installed in the mounting groove, the positioning posts and positioning grooves are aligned, thereby ensuring the accurate installation of the scraping seat 40.

[0065] See Figure 16 and 17 As shown, the base station's docking position is equipped with... Figure 16 The mounting slot 6 shown; as Figure 17 The scraper seat 40 shown can be placed directly into the mounting slot 6. For example... Figure 18 and 19As shown, the vertical wall 41 of the scraper seat 40 is provided with multiple snap-fit ​​structures 411, and the mounting groove 6 has a fixing structure adapted to the snap-fit ​​structure 411. After the user installs the scraper seat 40 into the mounting groove 6, the snap-fit ​​structure 411 connects with the fixing structure, fixing the scraper seat 40 in the mounting groove 6, making the connection of the scraper seat 40 more secure. In this way, when cleaning the cleaning actuator, the scraper seat will not be pulled away from the mounting groove by the rotating cleaning actuator due to an unstable connection.

[0066] like Figure 6 or Figure 10 As shown, the two ends of the second vertical rib 2222 and the connecting plate 221 are connected to the support column 21 or the side wall of the cleaning tank at the corresponding positions. The plane where the top of the support column 21 is located is an inclined plane that can be parallel to the slope 3. The first cleaning structure 20 is set at the top of the support column 21, which not only makes the plane where the upper surface of the first cleaning structure 20 is located an inclined plane, but also makes the top surface of the scraper 22 extend beyond the top of the support column 21 or be flush with the top of the support column 21, ensuring that the cleaning actuator 2 can smoothly abut against the scraper 22 without being affected by the support column 21.

[0067] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 6 , Figure 12 As shown, the second cleaning structure 10 includes a rotating shaft 11 and at least one extending arm 13. The rotating shaft 11 is disposed within the cleaning tank and can rotate relative to the cleaning tank. It is understood that, to better accommodate the cleaning actuator 2, the opening of the cleaning tank is adapted to the cleaning actuator 2 when the cleaning actuator 2 is located within the cleaning tank. To achieve a better self-cleaning effect for the cleaning actuator 2, the first cleaning structure 20 is also adapted to the cleaning actuator 2, meaning that the support column 21 is located at the axis. Therefore, to achieve a good scraping effect on the inner wall (bottom wall and side wall) of the cleaning tank, the circle formed by the rotation of the second cleaning structure 10 needs to be coaxial with the cleaning tank; therefore, the rotating shaft 11 is sleeved on the bottom end of the support column 21. To ensure smooth rotation of the rotating shaft 11 relative to the support column 21, the rotating shaft 11 can be sleeved on the bottom end of the support column 21 using a sleeve 12. The sleeve 12 can be made of wear-resistant and self-lubricating materials such as POM or nylon. Of course, lubricating oil can also be provided between the rotating shaft 11 and the support column 21, so that the contact part is more sensitive to friction and follows the rotation of the cleaning actuator 2.

[0068] In some embodiments of this application, such as Figure 10As shown, the rotating shaft 11 is sleeved on the bottom end of the support column 21 via the bearing assembly 17, thereby reducing the friction between the rotating shaft 11 and the support column 21, making the rotating shaft 11 rotate more smoothly around the support column 21. One possible structure of the bearing assembly 17 is as follows: it includes a bearing 171 and a bearing seat 172, wherein the bearing seat 172 is sleeved on the support column 21. The side of the support column 21 away from the scraper 22 has a concave stepped surface. When the support column 21 is installed in the mounting groove, a receiving groove for accommodating the bearing seat 172 is formed between the stepped surface and the bottom wall of the mounting groove. When the bearing seat 172 is sleeved on the support column 21, its bottom end abuts against the bottom wall of the cleaning groove, and its top end abuts against the stepped surface. This allows the bearing seat 172 to support not only the second cleaning structure 10 but also the support column 21, thereby increasing the support for the first cleaning structure 20 and preventing it from being deformed by the cleaning actuator 2 during cleaning. Since the support column 21 is connected to the bottom wall of the mounting groove by a snap-fit, it is convenient to quickly disassemble the first cleaning structure 20 and the scraping seat 40 in the mounting groove, and to facilitate the replacement of the bearing 171.

[0069] In some embodiments of this application, such as Figure 4 , Figure 6 , Figure 12 As shown, at least one or all of the extension arms 13 are provided with cleaning elements 16. The extension arms 13 extend from the rotation axis 11 toward the wall of the cleaning tank to guide the direction of the cleaning elements 16. Since the cleaning elements 16 abut against the wall of the cleaning tank, the inner wall of the cleaning tank will provide friction to the cleaning elements 16 to prevent the rotation of the second cleaning structure 10. Therefore, the number of cleaning elements 16 cannot be too large. In this embodiment, there is only one cleaning element 16, but there can also be two or more. This embodiment does not make a specific limitation. In specific implementation, the friction between the extension arm 13 and the bottom wall of the cleaning tank can be adjusted by increasing the number of cleaning elements 16 and adjusting the hardness of the cleaning elements 16, thereby adjusting the rotation speed and the scraping effect.

[0070] Furthermore, in some embodiments of this application, such as Figure 4 , Figure 6 , Figure 12 As shown, one possible structure for the extension arm 13 is that the bottom of the extension arm 13, which has a cleaning element 16, has at least one slot, and the cleaning element 16 is detachably disposed in the slot (e.g., Figure 15(As shown). Another possible structure for the extension arm 13 is that the cleaning component 16 and the extension arm 13 have mutually cooperating snap fasteners (either male or female). The cleaning component 16 is installed on the extension arm 13 by engaging the snap fasteners, or disassembled from the extension arm 13 by separating the snap fasteners. This operation is quick and convenient. As the cleaning component 16 continuously scrapes the walls of the cleaning tank, it will inevitably deform. When the cleaning component 16 deforms to the point of poor cleaning effect, it can be replaced with a new one. The end of the cleaning component 16 extends beyond the extension arm 13 and abuts against the side wall of the cleaning tank, while the bottom of the cleaning component 16 extends beyond the bottom of the extension arm 13 and abuts against the bottom wall of the cleaning tank. This allows the cleaning component 16 to scrape not only the bottom wall of the cleaning tank but also the side walls, ensuring the cleaning tank is thoroughly cleaned.

[0071] To achieve better cleaning of the bottom wall of the cleaning tank, in some embodiments of this application, such as... Figure 4 As shown, the extension arm 13 is eccentrically mounted on the rotating shaft 11. The extension arm 13 extends in a direction tangential to the rotating shaft 11, so that when the second cleaning structure rotates, the dirt adhering to the bottom wall of the cleaning tank generates centrifugal force as the extension arm 13 rotates, thereby throwing the dirt to the edge of the inner wall of the cleaning tank, and the dirt can slide along the edge of the inner wall of the cleaning tank.

[0072] Since the surface where the first cleaning structure is located is an inclined plane, please refer to... Figure 3 , Figure 5 , Figure 7 Therefore, there is an angle between the surface where the first cleaning structure 20 is located and the surface where the second cleaning structure 10 is located, and the second cleaning structure 10 is higher than or flush with the lowest point of the surface where the first cleaning structure 20 is located. Therefore, it is more appropriate to place the hollow area 23 here. To ensure that the second cleaning structure 10 has sufficient rotational power, such as... Figure 4 As shown, a contact portion is provided above the extension arm 13. As the second cleaning structure rotates, the contact portions on different extension arms 13 continuously come into contact with the cleaning support, increasing the probability of the second cleaning structure contacting the cleaning actuator 2, thereby enabling the cleaning actuator 2 to continuously provide the second cleaning structure with rotational power.

[0073] Furthermore, such as Figure 4As shown, since the scraper 22 at the lower part of the groove on the first cleaning structure may be in a broken state, the contact part contacts the cleaning actuator 2 at the broken point. To avoid interference between the extension arm 13 and the scraper 22 when the second cleaning structure rotates, the contact part is located at the end of the extension arm 13, and the end of the extension arm 13 has an upward boss 131, with the contact part being the upper surface of the boss 131. To avoid interference between other scrapers 22 and the boss, other scrapers 22 are provided with clearance grooves 223 at positions corresponding to the boss 131. To ensure stable support for the cleaning actuator 16, in some embodiments of this application, such as... Figure 4 As shown, the boss 131 on the extension arm 13 with the cleaning component 16 is a protrusion, and the slot runs through the entire extension arm 13. The bosses 131 on other extension arms 13 are all recessed upwards, and multiple weight-reducing strip holes 132 are provided on the extension arm 13 at intervals to reduce the weight of the extension arm 13 and reduce the static friction force of the second cleaning structure rotating around the support column 21.

[0074] To increase friction, in some embodiments of this application, such as Figures 2-3 As shown, the contact portion has multiple raised friction blocks 133.

[0075] In some embodiments of this application, such as Figure 5 As shown, to ensure sufficient rotational power for the second cleaning structure 10, the second cleaning structure 10 also includes a contact ring 19. The contact ring 19 is disposed around the rotating shaft 11, and at least part or all of the extension arms 13 are connected to the contact ring 19 to ensure the connection strength between the contact ring 19 and the rotating shaft 11. The contact ring 19 is located at the clearance groove 223 to prevent the contact ring 19 from colliding with the first cleaning structure 20 and interfering with the rotation of the second cleaning structure 10. When the cleaning actuator 2 rotates, the contact ring 19 more smoothly transmits power to the second cleaning structure 10, preventing insufficient friction caused by excessive wear of the cleaning actuator 2 and avoiding the phenomenon that the extension arms 13 cannot rotate.

[0076] Furthermore, in order to reduce the resistance of the second cleaning structure 10 to the cleaning actuator 2, a plurality of friction blocks 133 are arranged sequentially around the circumference of the rotating shaft 11 on the edge of the contact ring 19 away from the rotating shaft 11, thereby increasing the radius between the friction blocks 133 around the rotating shaft 11, so as to increase the lever arm of the friction blocks 133 rotating around the rotating shaft 11. As a result, when the cleaning actuator 2 can provide the torque required to rotate the second cleaning structure 10, the friction force acting on the friction blocks 133 by the cleaning actuator 2 is minimized, further reducing the speed loss of the cleaning actuator 2 and ensuring the cleaning efficiency of the cleaning actuator 2 and the first cleaning structure 20.

[0077] Furthermore, in some embodiments of this application, such as Figure 5 , Figure 6As shown, multiple fan-shaped baffles 18 are spaced apart between the extension arm 13 and the rotating shaft 11. Optionally, there are 3 or 4 fan-shaped baffles 18, and the embodiments of this application do not impose specific limitations. The fan-shaped baffles 18 not only strengthen the connection between the contact ring 19 and the rotating shaft 11, but also prevent sewage from splashing out from the bottom of the cleaning tank, avoiding secondary contamination of the cleaning actuator 2. The gap between two adjacent fan-shaped baffles 18 allows sewage after cleaning the cleaning actuator 2 to flow into the cleaning tank. The cleaning component 16 can be located below the fan-shaped baffles 18. The extension arm 13 is located below the fan-shaped baffles 18 to avoid blocking the gap between two adjacent fan-shaped baffles 18, ensuring that sewage can flow smoothly into the cleaning tank.

[0078] It should be noted that the contact ring 19 is placed horizontally, so that the plane on which the contact ring 19 is located is parallel to the bottom wall of the cleaning tank, thus forming an angle between it and the upper surface of the first cleaning structure 20, so that the contact ring 19 can abut against the cleaning actuator 2 in the hollow area 23.

[0079] During the cleaning process of the cleaning component 16 of the second cleaning structure 10, the rotation of the second cleaning structure 10 may cause wastewater in the cleaning tank to be carried up and splashed, causing secondary pollution to the cleaning actuator 2. Therefore, as Figure 7 As shown, in the solution provided in this embodiment, a baffle plate 101 is added to the second cleaning structure 10. More specifically, as... Figure 7 A fan-shaped baffle 101 is provided on one side of the extended arm 13 shown. For example... Figure 7 In the example shown, the second cleaning structure 10 includes four extension arms 13, each of which has a baffle plate 101 on one side. Figure 7 To distinguish it from surrounding structural features, cross-sectional lines are drawn on the baffle plate 101. These cross-sectional lines are not part of the actual cross-section. The baffle plate 101 prevents wastewater from splashing upwards from the underside of the extension arm. However, the presence of the baffle plate 101 also prevents wastewater from entering the cleaning tank. Therefore, multiple drainage holes 102 can be provided on the side of the baffle plate 101 that connects to the extension arm 13, allowing wastewater to enter the cleaning tank through the drainage holes 102.

[0080] Further, see Figure 17 As shown, a water-retaining eaves 45 may be provided on the upper part of the inner wall of the vertical wall 41 of the scraper seat 40. For example... Figure 17As shown, the scrubbing seat 40 has a circular cleaning area on the left and a circular cleaning area on the right. The left-side water-retaining eaves 45 cover 1 / 2 to 3 / 4 of the circumference of the left-side circular cleaning area; similarly, the right-side water-retaining eaves 45 cover 1 / 2 to 3 / 4 of the circumference of the right-side circular cleaning area. The portions of the left-side circular cleaning area without water-retaining eaves are adjacent to those of the right-side circular cleaning area without water-retaining eaves. That is, the overlapping portions of the left and right circular cleaning areas and a portion of the area behind the cleaning tank lack water-retaining eaves. The function of the water-retaining eaves 45 is also to prevent wastewater from splashing up inside the cleaning tank.

[0081] In addition, from Figure 16 and 17 It can also be seen that neither the circular cleaning area on the left nor the circular cleaning area on the right is a complete circle. The two circular cleaning areas overlap. A triangular-like area is formed on both the rear and front sides of the cleaning tank. In this embodiment, the cleaning component 16 on the second cleaning structure 10 scrapes the sewage and dirt to a position similar to... Figure 16 The wastewater flows into the rear triangular area 64 after passing through the primary filter 61 in this rear triangular area.

[0082] In one embodiment of this application, such as Figures 11-14 As shown, another possible structure for the second cleaning structure is as follows: the second cleaning structure may further include a roller 15, positioned at the low end of the cleaning tank opening. The roller 15 has a contact portion and a first meshing tooth, while the rotating shaft 11 has a second meshing tooth. The first and second meshing teeth mesh together. When the contact portion rotates under the frictional force provided by the cleaning actuator 2, the meshing of the first and second meshing teeth drives the rotating shaft 11 to rotate around the support column 21, thereby causing the second cleaning structure 10 to rotate and clean the cleaning tank. During this process, since the roller 15 is constantly in contact with the cleaning actuator 2, it is continuously subjected to frictional force and rotates, thus providing more power for the rotation of the second cleaning structure.

[0083] To achieve the rotation of the roller 15, one possible structure for the roller 15 is that both ends of the roller 15 have protruding roller shafts 14, and the roller shafts 14 are rotatably mounted on the scraper 22; another possible structure is as follows: Figures 7-10 As shown, the roller 15 includes an axle and a contact wheel sleeved on the outer periphery of the axle. The axle is rotatably mounted on the scraper 22. As long as the roller 15 can rotate, this embodiment does not impose any specific limitations.

[0084] Furthermore, in some embodiments of this application, such as Figures 11-14As shown, the axle of the roller 15 passes through the axis of the rotating shaft 11. Along the direction of the axle, the end of the roller 15 is provided with a first bevel gear 141 structure, and the rotating shaft 11 is provided with a second bevel gear 111 structure. The first bevel gear 141 structure meshes with the second bevel gear 111 structure to convert the rotation of the roller 15 into the rotation of the rotating shaft 11.

[0085] To increase the frictional force that drives the roller 15 to rotate around the shaft 11, in embodiments of this application, such as... Figures 7-10 As shown, the roller 15 has multiple ribs 151 on its wall. The multiple ribs 151 serve as contact parts that contact the cleaning actuator 2. The ribs 151 can increase the contact area and pressure between the roller 15 and the cleaning actuator 2, thereby increasing the friction.

[0086] To ensure that wastewater leaves the cleaning tank promptly and to prevent excessive wastewater from overflowing, such as... Figure 2 , Figure 4 as well as Figure 10 As shown, a suction port 50 is provided at the cleaning tank, and a sewage tank and a negative pressure pump are provided in the base station. The suction port 50 is connected to the negative pressure pump, and the sewage tank is located on the path connecting the drain pipe and the negative pressure pump. Under the negative pressure of the negative pressure pump, the sewage in the cleaning tank can be accelerated to enter the sewage tank through the filter components, so as to realize the timely treatment of sewage.

[0087] To prevent large solid objects from clogging the drain pipe, such as Figure 2 , Figures 4-6 as well as Figure 12 As shown in the embodiment of this application, a suction filter 60 is provided at the suction port 50, which can block solid dirt from passing through.

[0088] Specifically, in some embodiments of this application, such as Figures 5-6 As shown, the suction filter 60 includes a primary filter 61 composed of grid-like vertical ribs and a secondary filter 62 located above the suction port. The primary filter 61 can block larger particles, hair, and lint, but it is less effective at blocking small solid dirt. The secondary filter 62 can further filter and block tiny solid dirt, thereby preventing blockage of the suction port 50 and ensuring its unobstructed flow.

[0089] Although the suction filter 60 can block most solid dirt, with repeated use, smaller pieces of dirt will still pass through the suction filter 60 and flow with the sewage to the suction port 50, causing blockage. Therefore, in some embodiments of this application, the cleaning tank is also equipped with a full water detection device to detect the liquid level in the cleaning tank and generate an alarm signal when the liquid level reaches a set value to remind the user that the suction port 50 is blocked and needs cleaning. At the same time, the base station is controlled to stop water supply.

[0090] Specifically, in some embodiments of this application, such as Figures 5-6 As shown, the full water detection device includes a detection float containing a magnet, and a Hall element is installed at the corresponding position of the magnet on the base station. When the suction port is blocked, the water level in the tank rises. When the water level rises to the point where the magnet inside the float attracts the magnet on the base station, the Hall signal is lost, thereby generating an alarm and controlling the base station to stop water supply.

[0091] In the embodiments of this application, such as Figures 2-4 as well as Figures 11-12 As shown, the bottom wall of the cleaning tank is an inclined surface facing away from the slope 3. The suction port 50 is located on the side of the bottom wall of the cleaning tank facing away from the slope 3, which facilitates the flow of sewage in the cleaning tank to the suction port 50. The larger the angle of the bottom wall of the cleaning tank relative to the plane, the better the scraping and cleaning effect of the cleaning component 16 on the bottom wall of the cleaning tank, the better the sewage discharge effect, and the stronger the contact strength between the cleaning actuator 2 and the first cleaning structure 20, so that the rotational power of the second cleaning structure 10 relative to the support column 21 is more sufficient. However, the inclination angle of the bottom wall of the cleaning tank cannot be too large, otherwise structural interference will occur. In the embodiment of this application, the inclination angle of the bottom wall of the cleaning tank is 1° to 5°, which can be 1°, 2°, 3°, 4° or 5°, or other angles, as long as it can guide the sewage to flow to the suction port 50 and not cause interference between other structures. This embodiment does not make specific limitations.

[0092] See Figure 7 and 17 As shown, the rear side of the horizontal filter screen is U-shaped. A suction device can be installed in the recessed area of ​​this U-shape to pump wastewater from the water tank 65 into the wastewater tank of the base station. See also... Figure 5 and Figure 7 As shown, the bottom of the water tank 65 is a slope, higher at the back and lower at the front, so that the sewage can collect in the concave area, making it easier for the suction device to suck it up.

[0093] In one possible embodiment of this application, such as Figures 2-3 , Figure 5 , Figure 7 as well as Figure 11As shown, the base station also includes a water injection structure 30, which is disposed within a cleaning tank. The water injection structure is a water channel extending from the edge of the cleaning tank to its center. During the rotation of the cleaning actuator 2, the water injection structure 30 can evenly distribute cleaning water onto the cleaning actuator 2, ensuring a good cleaning effect. To ensure that the cleaning actuator 2 is fully wetted by cleaning water when passing through the water injection structure 30, in some embodiments of this application, such as... Figures 2-3 , Figure 5 , Figure 7 as well as Figure 11As shown, the water injection structure 30 can be structured as follows: it includes a water injection plate 32, a vertical edge 33 on one side of the water injection plate 32, and a guide edge 34 on the other side of the water injection plate 32. Both ends of the vertical edge 33 and both ends of the guide edge 34 are connected to the corresponding support column 21 or the wall of the cleaning tank to ensure the strength of the water injection structure 30 and prevent it from being crushed by the pressure of the cleaning actuator 2. The guide edge 34 is inclined towards the bottom of the cleaning tank, guiding the cleaning water not absorbed by the cleaning actuator 2 into the cleaning tank, rather than accumulating in the water injection structure 30, thus reducing the load on the water injection structure 30. Alternatively, the end of the water injection plate 32 located at the support column 21 is provided with a drain hole 224, allowing the cleaning water not absorbed by the cleaning actuator 2 to flow into the cleaning tank instead of accumulating in the water injection channel. The top of the guide edge 34 is flush with the bottom of the vertical edge 33. The water injection plate 32 is a curved surface that transitions from the top of the guide edge 34 to the top of the vertical edge 33. The end of the water injection plate 32 away from the support column 21 passes through the wall of the cleaning tank to form the bottom wall of the water injection tank 31. Cleaning water flows along the water injection plate 32 from the wall of the cleaning tank to the support column 21, and then from the top of the guide edge 34 to the top of the vertical edge 33, thus covering the entire water injection plate 32. When the cleaning actuator 2's cloth rotates to the water injection structure 30, because the surface of the water injection plate 32 is curved, the cloth can more easily contact the entire surface of the water injection plate 32, thus more easily absorbing cleaning water. Furthermore, the water injection channel is provided with multiple raised strips 35 to reduce the liquid flow velocity. Specifically, the raised strips 35 are located on the water injection plate 32 and on one side of the water injection plate 32. The raised strips 35 not only strengthen the water injection plate 32 but also block the water flow to a certain extent, slowing down the flow velocity of the cleaning water flowing from the water injection channel. This allows the cleaning water to be fully absorbed by the cleaning actuator 2, preventing excessive water flow that would cause the cleaning water to flow into the cleaning tank before being absorbed by the cleaning actuator, thus avoiding waste. Since the water injection plate 32 is curved, the raised strips 35 are also curved. In some embodiments of this application, the length of the multiple raised strips 35 gradually decreases along the liquid flow direction, so that the ability of the raised strips 35 to block the flow of cleaning water gradually weakens, ensuring that the cleaning water is evenly distributed in the water injection channel. It is understandable that as the cleaning water flows from the edge of the cleaning tank in the water injection channel to the center of the cleaning tank, the cleaning actuator 2 continuously absorbs the cleaning water. Therefore, the amount of cleaning water flowing in the water injection channel gradually decreases. As a result, the ability of the raised strip 35 to block the flow of cleaning water gradually weakens, which enables the cleaning water in the water injection channel to be evenly distributed.

[0094] Further, see Figure 5 In the example shown, the overlap between the circular cleaning areas on the left and right has a central vertical wall. See [link / reference needed]. Figure 5Area C. The central vertical wall is recessed, and the scraping ribs 22 of the circular cleaning zones on the left and right sides span across the top of the central vertical wall.

[0095] While applying pressure to the first cleaning structure, the cleaning actuator 2 also applies pressure to the contact portion, which can easily cause the second cleaning structure 10 to tilt. The side of the second cleaning structure 10 located in the hollow area 23 is lower than the side facing away from the hollow area 23. Therefore, when the extension arm 13 rotates to the side facing away from the hollow area, the cleaning component 16 cannot effectively scrape against the wall of the cleaning tank. Therefore, in some embodiments of this application, please refer to... Figures 20-22 As shown, the first cleaning structure 20 is provided with a pressing structure 24, which is used to limit the position of the second cleaning structure 10, ensuring that the second cleaning structure 10 remains in contact with the bottom wall of the cleaning tank during rotation, thus ensuring a good scraping effect on the tank wall. Specifically, one possible structure for the pressing structure 24 is that a pressing plate is provided at the free end of the contact portion, and the pressing structure 24, which abuts against the pressing plate, is provided on the side of the first cleaning structure 20 away from the hollow area, thus limiting the position of the second cleaning structure and preventing the second cleaning structure 10 from tilting towards the hollow area due to the pressure of the cleaning actuator 2. This ensures that the cleaning actuator 16 maintains good contact with the bottom wall of the cleaning tank during rotation with the extension arm 13, guaranteeing a good cleaning effect of the second cleaning structure 10 on the cleaning tank.

[0096] Specifically, in some embodiments of this application, please refer to Figures 20-22As shown, one possible implementation of the pressing structure 24 is as follows: it includes a pressing seat 241, a support wheel shaft 242, and a support roller 243. One end of the pressing seat 241 is located on the side of the water injection structure 30 away from the water injection tank, and the other end has a receiving groove that opens toward the second cleaning structure 10. The two ends of the support wheel shaft 242 are respectively inserted into the groove wall of the receiving groove on the corresponding side. The support roller 243 is rotatably mounted on the support wheel shaft 242. A part of the support roller 243 is received in the receiving groove, and the other part protrudes out of the receiving groove and abuts against the pressing plate. During the rotation of the second cleaning structure 10, even if it tilts towards the hollow area due to pressure from the cleaning actuator 2, when the extension arm 13 rotates to the pressing structure 24, the pressing plate abuts against the support roller 243. As the support roller 243 rotates around the support wheel shaft 242 with the extension arm 13, it presses the pressing plate downwards, causing the extension arm 13 to move towards the bottom wall of the cleaning tank, ensuring good contact between the cleaning component at the bottom of the extension arm 13 and the bottom wall of the cleaning tank. The wheel surface of the support roller 243 abuts against the upward-facing side of the extension arm 13. The friction generated by the contact between the wheel surface of the support roller 243 and the extension arm 13 drives the support roller 243 to rotate, thereby reducing the resistance to the rotation of the second cleaning structure 10 and better guiding its rotation.

[0097] This application also provides a cleaning system including a cleaning robot and a base station as described above. The cleaning robot has a cleaning actuator 2, which is movable relative to the robot's body for cleaning the area to be cleaned. The cleaning robot has a self-propelled function and can travel to the area to be cleaned to perform cleaning tasks according to user instructions.

[0098] After completing its cleaning task, the cleaning robot moves to the base station and uses ramp 3 to allow the cleaning actuator 2 to enter the cleaning tank. The cleaning actuator 2 rotates, generating friction with the first cleaning structure, which rubs the dirt adsorbed on the cleaning actuator 2 into the wastewater. The wastewater is then scraped from the cleaning actuator 2 into the cleaning tank and flows into the wastewater tank through the wastewater outlet. During its rotation, the cleaning actuator 2 passes through the water injection structure 30, which evenly distributes cleaning water onto the relatively dry surface of the cleaning actuator 2, continuing the cleaning process until the cleaning actuator 2 stops moving, completing its self-cleaning process.

[0099] During the self-cleaning process of the cleaning actuator 2, the cleaning actuator 2 drives the second cleaning structure to rotate through the contact part to scrape the cleaning tank. This scrapes away the dirt adsorbed on the tank wall, preventing dirt from accumulating, breeding bacteria, and producing odors.

[0100] Cleaning robots can be, but are not limited to, floor scrubbers, sweeping robots, mopping robots, or window cleaning robots.

[0101] Based on the inventive design concept of the above embodiments, the structure in the base station that achieves self-cleaning of the cleaning tank by means of external equipment can be considered an independent product. This product can be installed as an accessory in a base station already purchased by the user, or on the base of a floor scrubber. Specifically, this application provides a cleaning assembly, which includes a scraper seat 40, a first cleaning structure 20, and a second cleaning structure 10. The scraper seat 40 has a cleaning tank, and the first cleaning structure 20 is disposed within the cleaning tank for cleaning the cleaning actuator 2 on a cleaning robot. The second cleaning structure 10 is movably disposed within the cleaning tank and is used to clean the cleaning tank. The second cleaning structure 10 has a cleaning element 16 and a contact portion. During self-cleaning, the cleaning actuator 2 moves, and the contact portion contacts the cleaning actuator 2, causing the second cleaning structure 10 to move, thereby driving the cleaning element 16 to clean the cleaning tank. This not only achieves self-cleaning of the cleaning actuator 2 but also cleans the cleaning tank containing the cleaning actuator 2, eliminating the need for manual cleaning of the cleaning tank by the user. Furthermore, there is no need to add a drive motor and transmission structure, making the structure simple, easy to implement, and low in cost.

[0102] For a detailed description, please refer to the text above; it will not be repeated here.

[0103] This application also provides another cleaning system, which includes a cleaning robot and a base station. The cleaning robot has a cleaning actuator 2, which is movable relative to the robot's body to clean the area to be cleaned. The cleaning robot has a self-propelled function and can travel to the area to be cleaned to perform the cleaning task according to user instructions. The base station has a docking position for the cleaning robot. The base station includes a cleaning tank, a first cleaning structure 20, and a second cleaning structure 10. The cleaning tank is located at the docking position. The first cleaning structure 20 is disposed in the cleaning tank and abuts against the cleaning actuator 2 to clean the actuator 2. The second cleaning structure 10 is rotatably disposed in the cleaning tank and includes a cleaning component 16 and a contact portion. The cleaning component 16 abuts against the tank wall, and the contact portion abuts against the cleaning actuator 2.

[0104] When the cleaning actuator 2 rotates within the cleaning tank for self-cleaning, it generates friction with the first cleaning structure 20, which rubs the dirt adsorbed on the cleaning actuator 2 into the wastewater, scrapes the wastewater from the cleaning actuator 2 into the cleaning tank, and then flows into the wastewater tank from the wastewater outlet. During rotation, the cleaning actuator 2 passes through the water injection structure 30, which evenly distributes cleaning water onto the relatively dry surface of the cleaning actuator 2 to continue the cleaning process until the cleaning actuator 2 stops moving, completing the self-cleaning process.

[0105] During the self-cleaning process of the cleaning actuator 2, the cleaning actuator 2 provides frictional force to drive the second cleaning structure 10 to rotate through the contact part. At this time, the cleaning component 16 rotates with the second cleaning structure 10 to scrape the cleaning tank. This scrapes away the dirt adsorbed on the tank wall, preventing dirt from accumulating, breeding bacteria, and producing odors.

[0106] When the cleaning actuator 2 rotates, the first cleaning structure 20 cleans the cleaning actuator 2 and forms a first area for cleaning the cleaning actuator. The second cleaning structure 10 is driven by the cleaning actuator 2 to clean the cleaning tank and forms a second area for moving the second cleaning structure 10.

[0107] Specifically, in some embodiments of this application, the first cleaning structure 20 includes a plurality of scrapers 22, which are spaced apart in the circumferential direction. When the cleaning actuator 2 rotates, it will sequentially contact the plurality of scrapers 22 to clean the cleaning actuator 2. When the cleaning actuator 2 rotates a full circle, a first area for cleaning the cleaning actuator 2 is formed between the scraper 22 that contacts the cleaning actuator 2 first and the scraper 22 that contacts the cleaning actuator 2 last. When the cleaning actuator 2 rotates, the second cleaning structure 10 is driven by the cleaning actuator 2 to clean the cleaning tank, forming a second area for moving the second cleaning structure 10. Since the cleaning requirements of the cleaning actuator 2 are higher than those of the cleaning tank, the area of ​​the first area is larger than the area of ​​the second area to ensure that more area of ​​the cleaning actuator 2 is cleaned by the first cleaning structure, thus ensuring a good cleaning effect for the cleaning actuator 2.

[0108] With the above structure, preferably, as follows: Figure 5As shown, the first and second regions are arranged alternately in the circumferential direction. During a complete rotation of the cleaning disc, the cleaning disc cleans the cloth on it during the first half-rotation, and during the second half-rotation, the rotation of the cleaning disc cleans the base station's groove. In other embodiments, the first and second regions can also be arranged alternately in the radial direction of the circle. One of the first and second regions is located in the central region of the cleaning actuator 2, and the other is located in the outer peripheral ring region of the cleaning actuator 2; alternatively, one of the second and first regions is located in the annular region between the center and edge of the cleaning actuator, and the other is located in both the central and outer peripheral ring regions outside the annular region. This embodiment does not impose specific limitations as long as the cleaning actuator 2 simultaneously abuts against both the first cleaning structure and the contact portion.

[0109] Cleaning robots can be, but are not limited to, floor scrubbers, sweeping robots, mopping robots, or window cleaning robots.

[0110] For other details, please refer to the above text, which will not be repeated here.

[0111] Application Scenario 1: When a user needs to clean a certain area, they input the coordinates of the area to be cleaned and the task of cleaning to be executed immediately into the cleaning system. The cleaning system then drives the cleaning robot to start and go to the area to be cleaned to perform the cleaning task.

[0112] After completing its cleaning task, the cleaning robot moves to the base station and uses ramp 3 to allow the cleaning actuator 2 to enter the cleaning tank. At this point, the cleaning actuator 2 rotates, generating friction with the first cleaning structure. This friction rubs the dirt adsorbed on the cleaning actuator 2 into the wastewater, which is then scraped from the cleaning actuator 2 into the cleaning tank and flows into the wastewater tank through the wastewater outlet. During its rotation, the cleaning actuator 2 passes through the water injection structure 30, which evenly distributes cleaning water onto the relatively dry surface of the cleaning actuator 2, continuing the cleaning process until the cleaning actuator 2 stops moving, completing its self-cleaning process.

[0113] Application Scenario 2:

[0114] When the user needs to perform deep cleaning of the cleaning component 1, the support column 21 can be separated from the bottom wall of the mounting slot, allowing the cleaning component 1 to be removed from the mounting slot of the base station via the scraper seat 40. Then, a spray nozzle or shower head can be used to spray the scraper seat 40 from top to bottom. Since the scraper seat 40 only has vertical walls and no bottom wall, the cleaning tank is open from top to bottom, preventing water accumulation during the spraying process and facilitating brush cleaning.

[0115] After deep cleaning the cleaning components, you can hold the edge of the scraping base 40 and align the bottom end of the support column 21 with the mounting position on the bottom wall of the base station mounting slot, then press it down to reinstall the cleaning components. The disassembly and reassembly are simple and easy to operate.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
