[0063] The following will describe in detail some embodiments of this disclosure with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0064] Please refer to Figure 1 and Figure 2 As shown in, an embodiment of this disclosure provides a cleaning device 100, which is applied to a cleaning base station 1000. The cleaning base station 1000 includes a base station main body 1001, and a docking position 1002 for a cleaning robot 2000 to dock is provided at the bottom of the base station main body 1001.

[0065] In some embodiments, the cleaning robot 2000 includes a main body 2001 and a cleaning member 2002 rotatably provided on the main body 2001. The cleaning member 2002 is used for mopping and wiping a surface to be cleaned. Among them, the cleaning member 2002 is provided at the bottom of the cleaning robot 2000. Exemplarily, the cleaning member 2002 is a rotary mop, and the number of the cleaning members 2002 is 2. The two cleaning members 2002 are arranged side by side at the rear side of the cleaning robot 2000. During the working process of the cleaning robot 2000, the cleaning robot 2000 can walk in a designated area, and at the same time, the cleaning member 2002 rotates. In this way, the cleaning robot 2000 can wipe and absorb dirt from the area passed through, achieving a cleaning effect on the surface.

[0066] It can be understood that the dirt mentioned in this disclosure can be sewage, dirt, etc. Among them, the sewage can be liquid water, or a mixture of liquid water and some dirt, etc., which are objects that can be wiped or absorbed by a mop; the dirt can be solids such as hair, lint, and sediment, or a mixture of solids and some liquid water, etc., which are objects that can be sucked away by a vacuuming method.

[0067] Please refer to Figure 2 and Figure 3, in some embodiments, the cleaning device 100 includes a chassis 10 and a cleaning rib disk 20. The chassis 10 is disposed at the docking position 1002 of the base station main body 1001. The cleaning rib disk 20 is rotatably arranged on the chassis 10. A first cleaning part 21 is provided at the top of the cleaning rib disk 20, and the first cleaning part 21 is used for frictionally contacting the cleaning part 2002 of the cleaning robot 2000. A second cleaning part 22 is provided at the bottom of the cleaning rib disk 20, and the second cleaning part 22 is used for contacting the chassis 10.

[0068] Exemplarily, after the cleaning rib disk 20 is installed on the chassis 10, the second cleaning part 22 is in frictional contact with the chassis 10.

[0069] Exemplarily, when the cleaning robot 2000 is located at the docking position 1002, the first cleaning part 21 is in frictional contact with the cleaning part 2002.

[0070] In some embodiments, the cleaning device 100 includes a limiting component 30. The limiting component 30 is connected to the chassis 10 and / or the cleaning rib disk 20. The limiting component 30 is used to prevent the cleaning rib disk 20 from continuing to rotate after it rotates a preset angle relative to the chassis 10 in a preset direction. The angle that the cleaning rib disk 20 rotates from the first stop state to the second stop state along the preset direction is greater than or equal to 360°. When the cleaning part 2002 is supported on the cleaning rib disk 20 and rotates, and the cleaning rib disk 20 is in a state of stopping rotation relative to the chassis 10, the cleaning part 2002 is cleaned by the first cleaning part 21. When the cleaning rib disk 20 rotates relative to the chassis 10, the chassis 10 is cleaned by the second cleaning part 22.

[0071] In the present disclosure, the cleaning rib disk 20 is driven by the cleaning part 2002, so that the second cleaning part 22 cleans the chassis 10. When the cleaning rib disk 20 is in a state of stopping rotation, the cleaning part 2002 rotates relative to the first cleaning part 21, so that the first cleaning part 21 cleans the cleaning part 2002. The chassis 10 and the cleaning part 2002 are cleaned together, reducing the dirt residue on the chassis 10. Moreover, the angle that the cleaning rib disk 20 rotates is greater than or equal to 360°, which enables the cleaning rib disk 20 to rotate at least one circle on the chassis 10. Therefore, the cleaning blind area can be effectively reduced, the cleaning effect can be improved, the dirt residue on the chassis 10 can be further reduced, the labor burden of the user can be reduced, and the user experience can be improved.

[0072] Please refer to Figure 4 , in some embodiments, the chassis 10 is cleaned by driving the cleaning rib disk 20 to rotate relative to the chassis 10 by the cleaning part 2002 rotating in the first direction S until the cleaning rib disk 20 stops rotating under the action of the limiting component 30 after rotating a preset angle, and the cleaning part 2002 continues to rotate in the first direction S to clean the cleaning part 2002.

[0073] In some embodiments, the cleaning member 2002 can drive the cleaning rib disk 20 to rotate relative to the chassis 10 in the second direction N to clean the chassis 10 until the cleaning rib disk 20 stops rotating under the action of the limiting component 30 after rotating a preset angle, and the cleaning member 2002 continues to rotate in the second direction N to clean the cleaning member 2002. The first direction S is opposite to the second direction N. The first direction S is one of the clockwise direction and the counterclockwise direction, and the second direction N is the other.

[0074] Exemplarily, when the cleaning robot 2000 enters the cleaning base station 1000 to perform a cleaning operation, the first direction S is the clockwise direction, the second direction N is the counterclockwise direction, the cleaning member 2002 rotates in the clockwise direction to drive the cleaning rib disk 20 to rotate relative to the chassis 10 to clean the chassis 10 until the cleaning rib disk 20 stops rotating under the action of the limiting component 30 after rotating a preset angle, and the cleaning member 2002 continues to rotate in the clockwise direction to clean the cleaning member 2002. After the cleaning member 2002 rotates a predetermined number of turns relative to the cleaning rib disk 20 in the clockwise direction, the cleaning member 2002 rotates in the counterclockwise direction to drive the cleaning rib disk 20 to rotate relative to the chassis 10 to clean the chassis 10 until the cleaning rib disk 20 stops rotating under the action of the limiting component 30 after rotating a preset angle, and the cleaning member 2002 continues to rotate in the counterclockwise direction to clean the cleaning member 2002, and so on in a cycle to achieve the cleaning of the cleaning member 2002 and the chassis 10.

[0075] Exemplarily, when the cleaning robot 2000 enters the cleaning base station 1000 to perform a cleaning operation, the first direction S is the counterclockwise direction, the second direction N is the clockwise direction. The cleaning member 2002 rotates in the counterclockwise direction to drive the cleaning rib disk 20 to rotate relative to the chassis 10 to clean the chassis 10 until the cleaning rib disk 20 stops rotating under the action of the limiting component 30 after rotating a preset angle, and the cleaning member 2002 continues to rotate in the counterclockwise direction to clean the cleaning member 2002. During this process, dirt generated by cleaning the cleaning member 2002 will remain on the chassis 10. After the cleaning member 2002 rotates a predetermined number of turns relative to the cleaning rib disk 20 in the counterclockwise direction, the cleaning member 2002 rotates in the clockwise direction to drive the cleaning rib disk 20 to rotate relative to the chassis 10 to clean the chassis 10 until the cleaning rib disk 20 stops rotating under the action of the limiting component 30 after rotating a preset angle, and the cleaning member 2002 continues to rotate in the clockwise direction to clean the cleaning member 2002, and so on in a cycle to achieve the cleaning of the cleaning member 2002 and the chassis 10.

[0076] Please refer to Figure 2In some embodiments, the base station body 1001 may be provided with a liquid supply channel (not shown in the figure), the liquid supply channel is connected to a liquid supply device, and the liquid supply device is used to provide a cleaning liquid, and the cleaning liquid may be water, a detergent, a mixture of water and detergent, etc. When performing a cleaning operation, the liquid supply device may output the cleaning liquid to at least one of the chassis 10 or the cleaning rib plate 20 through the liquid supply channel, so as to flush the chassis 10 and\or the cleaning member 2002 of the cleaning robot 2000 with the cleaning liquid, thereby achieving a better cleaning effect.

[0077] Illustratively, when the cleaning member 2002 is supported on the cleaning rib plate 20 and drives the cleaning rib plate 20 to rotate, the liquid supply device can output cleaning liquid into the bottom plate 10 through the liquid supply channel, so that the second cleaning part 22 can clean the bottom plate 10.

[0078] Illustratively, when the cleaning member 2002 is supported on the cleaning rib plate 20 and rotates relative to the cleaning rib plate 20, the liquid supply device can output cleaning liquid to the cleaning rib plate 20 through the liquid supply channel. The cleaning liquid in the cleaning rib plate 20 wets the cleaning member 2002, making it easier for the first cleaning part 21 to clean the cleaning member 2002.

[0079] In some embodiments, the bottom plate 10 includes a liquid injection port 101, and the liquid supply channel is connected to the liquid injection port 101. The cleaning liquid is output to the bottom plate 10 or the cleaning rib plate 20 through the liquid injection port 101.

[0080] In some embodiments, the base station body 1001 includes the liquid injection port 101 , and the base station body 1001 directly outputs the cleaning liquid to at least one of the bottom plate 10 or the cleaning rib plate 20 through the liquid injection port 101 .

[0081] In some embodiments, Figure 2 As shown, the bottom plate 10 includes a first bottom wall 11 and a first side wall 12. The first side wall 12 is connected to the first bottom wall 11. The first side wall 12 surrounds at least part of the edge of the first bottom wall 11 to form a first chamber 11a. The cleaning rib plate 20 is disposed in the first chamber 11a.

[0082] In some embodiments, the liquid injection port 101 is disposed on the first side wall 12 , and a connecting tube 102 communicating with the liquid injection port 101 is disposed on a side of the first side wall 12 away from the first chamber 11 a , and is connected to the liquid supply channel through the connecting tube 102 .

[0083] Illustratively, when the cleaning member 2002 is supported on the cleaning rib plate 20 and drives the cleaning rib plate 20 to rotate, the cleaning liquid is output into the first chamber 11a through the liquid injection port 101. As the cleaning rib plate 20 rotates, the cleaning liquid flows to various areas of the first chamber 11a, which is beneficial to improving the cleaning effect of the chassis 10.

[0084] In some embodiments, when the cleaning rib disk 20 is in the first stop state or the second stop state, the liquid injection port 101 is opposite to the cleaning rib disk 20 and is in fluid communication therewith.

[0085] Exemplarily, when the cleaning member 2002 drives the cleaning rib disk 20 to rotate by a preset angle and the cleaning member 2002 is in the first stop state or the second stop state, at this time, the cleaning rib disk 20 is opposite to the liquid injection port 101, and the cleaning liquid is output to the first cleaning part 21 through the liquid injection port 101. Since the first cleaning part 21 supports the cleaning member 2002, the cleaning liquid injected through the liquid injection port 101 can wet the cleaning member 2002.

[0086] Please refer to Figures 5 to 7 , in some embodiments, the chassis 10 includes a sewage extraction port 13, a part of the first bottom wall 11 is recessed to form a second chamber 11b, and the second chamber 11b communicates with the outside of the chassis 10 through the sewage extraction port 13.

[0087] Exemplarily, the second chamber 11b is located in the middle of the chassis 10. When the cleaning robot 2000 enters the cleaning base station 1000 to perform a cleaning operation, the dirt generated by cleaning the chassis 10 and the cleaning member 2002 flows to the second chamber 11b and is discharged to the outside of the chassis 10 through the sewage extraction port 13. For example, it is discharged into the sewage tank of the cleaning base station communicated with the sewage extraction port 13, or is communicated through the cleaning base station 1000 to the sewer pipe outside the cleaning base station 1000.

[0088] Exemplarily, the sewage extraction port 13 is located at the lowest point of the second chamber 11b, which is beneficial to the dirt flowing to the sewage extraction port 13 under the action of gravity, reduces the risk of blockage caused by the dirt staying and accumulating on the second chamber 11b, and facilitates the discharge of the dirt.

[0089] In some embodiments, a filtering device 14 is covered above the second chamber 11b, and the first chamber 11a communicates with the second chamber 11b through the filtering device 14. The filtering device 14 is at least used to filter the sewage in the dirt, block the solid garbage from entering the second chamber 11b, and reduce the risk of blockage of the sewage extraction port 13.

[0090] Exemplarily, when the cleaning rib disk 20 rotates relative to the chassis 10, the dirt generated by the second cleaning part 22 cleaning the first chamber 11a enters the second chamber 11b through the filtering device 14.

[0091] Exemplarily, when the cleaning rib disk 20 drives the chassis 10 to rotate, the dirt from cleaning the cleaning member 2002 by the first cleaning part 21 falls into the first chamber 11a. When the cleaning rib disk 20 rotates relative to the chassis 10, the dirt generated by the second cleaning part 22 cleaning the first chamber 11a and the dirt generated by the cleaning member 2002 enter the second chamber 11b through the filtering device 14.

[0092] In some embodiments, the filtering device 14 has a first filter mesh portion 141, and the first filter mesh portion 141 is at least used to filter sewage in the dirt. Exemplarily, there are a plurality of first filter mesh portions 141, and the plurality of first filter mesh portions 141 are spaced apart and distributed on the filtering device 14. During the cleaning process, solid garbage in the dirt is filtered out by the first filter mesh portion 141 and remains on the filtering device 14.

[0093] It can be understood that the inner diameter and shape of the first filter mesh portion 141 can both be configured according to the type of dirt. For example, the first filter mesh portion 141 can be circular or strip-shaped, and the present disclosure does not limit this.

[0094] It should be noted that during the filtering process of the first filter mesh portion 141, there may also be a situation where some fine dirt passes through the first filter mesh portion 141 and is discharged into the second chamber 11b. This part of the dirt can be discharged through the dirt extraction port 13 or manually cleaned, and the present disclosure does not limit this.

[0095] In some embodiments, the filtering device 14 includes a second bottom wall 14a, and the second bottom wall 14a is connected to the first bottom wall 11. Along the thickness direction of the second bottom wall 14a, the first filter mesh portion 141 penetrates through the second bottom wall 14a.

[0096] In some embodiments, the filtering device 14 includes a second side wall 14b and a second filter mesh portion 142. The second side wall 14b is connected to the first side wall 12 and the second bottom wall 14a. Along the thickness direction of the second side wall 14b, the second filter mesh portion 142 penetrates through the second side wall 14b. During the process of the cleaning member 2002 driving the cleaning rib disk 20 to rotate, some dirt is discharged into the second chamber 11b through the second filter mesh portion 142. Since the second filter mesh portion 142 is located on the second side wall 14b, dirt is not likely to stack on the second side wall 14b, which is beneficial to improving the sewage discharge efficiency.

[0097] Exemplarily, there are a plurality of second filter mesh portions 142, and the plurality of second filter mesh portions 142 are spaced apart and distributed on the second side wall 14b.

[0098] It can be understood that the inner diameter and shape of the second filter mesh portion 142 can both be configured according to the type of dirt. For example, the second filter mesh portion 142 can be circular or strip-shaped, and the present disclosure does not limit this.

[0099] In some embodiments, the area of a single mesh hole of the second filter mesh portion 142 is larger than that of a single mesh hole of the first filter mesh portion 141. In this way, at least the following effects can be achieved: on the one hand, the fluff-like garbage falling on the cleaning member 2002 will form clusters due to the scraping of the cleaning rib plate 20. After forming clusters, the garbage is larger. The second filter mesh portion 142 allows the larger clustered fluff garbage to drain downward into the second chamber 11b, and the fluff in the second chamber 11b is broken up into clusters due to the flushing of the water flow and can be sucked away by the sewage suction port 13; on the other hand, the second filter mesh portion 142 can block garbage that is large in itself, such as screws, building block particles, etc. Through the cooperation of the first filter mesh portion 141 and the second filter mesh portion 142, the sewage discharge effect and efficiency of the cleaning device can be further improved.

[0100] In some embodiments, the filter device 14 is detachably connected to the chassis 10, which is convenient for disassembly for replacement or cleaning. The detachable connection methods include but are not limited to snap connection, bolt connection, interference fit, etc.

[0101] In some embodiments, the range within which the cleaning rib plate 20 rotates relative to the chassis 10 passes through the area where the first filter mesh portion 141 is located.

[0102] Exemplarily, during the process of the cleaning member 2002 driving the cleaning rib plate 20 to rotate, the cleaning rib plate 20 cleans the first chamber 11a, and during the process of driving the dirt to the first filter mesh portion 141, the cleaning rib plate 20 also cleans the area where the first filter mesh portion 141 is located, reducing the risk of dirt accumulating in the area where the first filter mesh portion 141 is located and causing the first filter mesh portion 141 to be blocked, which is beneficial to improving the filtering efficiency and sewage discharge efficiency of the first filter mesh portion 141 and enhancing the overall cleaning effect.

[0103] Please refer to Figure 4 , in some embodiments, there are two cleaning rib plates 20. The two cleaning rib plates 20 are arranged along the left-right direction of the chassis 10, and the filter device 14 is arranged between the two cleaning rib plates 20. The range within which the two cleaning rib plates 20 rotate relative to the chassis 10 passes through the area where the first filter mesh portion 141 is located, further enhancing the cleaning effect on the first chamber 11a and the first filter mesh portion 141. Among them, the left-right direction is the direction perpendicular to the direction in which the cleaning robot 200 enters and exits the cleaning base station 1000 in the horizontal plane.

[0104] In some embodiments, the two first rotation circles formed by the rotation of the two cleaning rib discs 20 are tangent or intersecting. Thus, the cleaning blind area between the two cleaning rib discs 20 on the chassis 10 can be made smaller, improving the cleaning effect on the chassis 10. Further, the intersecting or tangent area can be located in the area where the first filter mesh portion 141 is located. In this way, the cleaning rib disc 20 can clean the area of the first filter mesh portion 141 more, achieving better cleaning of the first filter mesh portion 141. Furthermore, the area where the first filter mesh portion 141 is located is within the area passed by the rotation of the two first rotation circles, enabling the cleaning areas of the two cleaning rib discs 20 to completely cover the area where the first filter mesh portion 141 is located, further enhancing the cleaning effect on the first chamber 11a and the first filter mesh portion 141.

[0105] Exemplarily, when the two first rotation circles formed by the rotation of the two cleaning rib discs 20 are tangent, the areas where the two first rotation circles are located completely cover the area where the first filter mesh portion 141 is located.

[0106] Exemplarily, when the two first rotation circles formed by the rotation of the two cleaning rib discs 20 intersect, during one rotation of the two cleaning rib discs 20, each cleaning rib disc 20 cleans the area of the first filter mesh portion 141 located within the intersecting area of the two first rotation circles, which is beneficial to improving the cleaning effect of this area.

[0107] In some embodiments, the first filter mesh portion 141 is arranged between the two cleaning rib discs 20 and is symmetrically arranged about the center line of the chassis 10 in the left-right direction. During the rotation of the cleaning rib disc 20, it evenly contacts the filtering device 14, avoiding excessive or insufficient local pressure caused by the asymmetry of the first filter mesh portion 141, balancing the cleaning force of the cleaning rib disc 20, and reducing the missed areas. The symmetrical first filter mesh portion 141 makes the liquid distribution more uniform when passing through the filtering device 14, which helps to prevent local blockage and improve the filtering efficiency at the same time.

[0108] In some embodiments, it is defined that the trajectory of the cleaning rib disc 20 rotating one week forms a first rotation circle. The range of the minimum distance h1 between any point on the edge of the first rotation circle and the first side wall 12 is h1 ≤ 1 cm. If h1 is greater than 1 cm, the cleaning blind area of the cleaning rib disc 20 for cleaning the first bottom wall 11 becomes larger, affecting the cleaning of the chassis 10. By limiting h1 ≤ 1 cm, it is beneficial to reduce the cleaning blind area of the cleaning rib disc 20 for cleaning the first bottom wall 11 and improve the overall cleaning effect.

[0109] Exemplarily, h1 can be any one of 0.1 cm, 0.2 cm, 0.3 cm, 0.4 cm, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm, 1.0 cm or the range composed of any two of them.

[0110] In some embodiments, the cleaning rib plate 20 rotates n times from the first stop state to the second stop state, where n is an integer and n≥1, so that the position of the cleaning rib plate 20 is the same in the first stop state and the second stop state, which facilitates the control of the position of the cleaning rib plate 20 and facilitates the output of the cleaning liquid into the cleaning rib plate 20 through the injection port 101.

[0111] In some embodiments, n≥2, the cleaning rib plate 20 rotates from the first stop state to the second stop state for at least two circles, and increasing the number of rotation circles of the cleaning rib plate 20 is beneficial to improving the cleaning effect of the cleaning rib plate 20 on the chassis 10.

[0112] See also Figures 7 to 10 In some embodiments, the cleaning rib tray 20 includes a central seat 20a and at least two arms 20b. The first end 201 of the arm 20b is fixedly connected to the central seat 20a, and the second end 202 of the arm 20b is away from the central seat 20a. The arm 20b rotates with the central seat 20a. The central seat 20a is connected to the bottom plate 10.

[0113] In some embodiments, the chassis 10 has a connecting seat 15 , and the central seat 20 a is circumferentially fixedly connected to the connecting seat 15 .

[0114] In some embodiments, the chassis 10 includes a mounting opening 103 that penetrates the first bottom wall 11 along the thickness direction of the first bottom wall 11. An extension wall 104 located in the first cavity 10a is disposed at the edge of the mounting opening 103. At least a portion of the extension wall 104 forms a connection seat 15.

[0115] For example, Figure 10 As shown, the extension wall 104 includes a first extension wall 1041 and a second extension wall 1042, the first extension wall 1041 is connected to the edge of the installation port 103, and the second extension wall 1042 is connected to the side of the first extension wall 1041 away from the first bottom wall 11. Along the thickness direction of the first bottom wall 11, the projection of the second extension wall 1042 is located within the projection of the first extension wall 1041. The center seat 20a has a first connection recess 203, and the second extension wall 1042 is disposed in the first connection recess 203. Exemplarily, the center seat 20a is clearance-matched with the first extension wall 1041, and the center seat 20a is clearance-matched with the second extension wall 1042, so as to reduce the friction between the center seat 20a and the first extension wall 1041 and the second extension wall 1042 during the rotation process.

[0116] Optionally, the extension wall 104 includes a first extension wall 1041. The first extension wall 1041 is connected to the edge of the mounting opening 103. The central seat 20a has a first connection recess 203. The first extension wall 1041 is disposed within the first connection recess 203. The central seat 20a and the first extension wall 1041 are in clearance fit, reducing the friction between the central seat 20a and the first extension wall 1041 during the rotation of the central seat 20a.

[0117] In some embodiments, the limiting component 30 is connected to the chassis 10 through the mounting opening 103 and partially protrudes from the extension wall 104. The central seat 20a is connected to the part of the limiting component 30 that protrudes from the extension wall 104. The part of the limiting component 30 that protrudes from the extension wall 104 is connected to the central seat 20a, so that the central seat 20a and the limiting component 30 can be relatively fixed, thereby allowing the central seat 20a and the extension wall 104 to be in clearance fit.

[0118] Exemplarily, the central seat 20a has a second connection recess 204. The first connection recess 203 and the second connection recess 204 have the same center. The outer diameter of the second connection recess 204 is smaller than the outer diameter of the first connection recess 203. The part of the limiting component 30 that protrudes from the extension wall 104 is disposed within the second connection recess 204. The part of the limiting component 30 that protrudes from the extension wall 104 is held within the second connection recess 204 by means of snap fit or interference connection.

[0119] Exemplarily, when the cleaning member 2002 drives the cleaning rib disk 20 to rotate, the central seat 20a drives the limiting component 30 to rotate. After the cleaning rib disk 20 rotates a preset angle, the limiting component 30 restricts the rotation of the central seat 20a.

[0120] In some embodiments, the limiting component 30 is disposed between the connection seat 15 and the central seat 20a. The projection of the limiting component 30 on the upper surface of the first bottom wall 11 is within the range where the central seat 20a is located. Thus, the limiting component 30 does not affect the cleaning range of the support arm 20b on the chassis 10, reducing the cleaning blind area and being beneficial to improving the overall cleaning effect.

[0121] In some embodiments, the support arm 20b includes a first surface 205 and a second surface 206. The first surface 205 faces away from the first bottom wall 11, and the first cleaning portion 21 is located on the first surface 205. The second surface 206 faces the first bottom wall 11, and the second cleaning portion 22 is located on the second surface 206.

[0122] In some embodiments, the second surface 206 of at least one support arm 20b is provided with the second cleaning portion 22.

[0123] In some embodiments, a plurality of support arms 20b are arranged at intervals along the circumferential direction of the central seat 20a.

[0124] Exemplarily, the support arm 20b includes two, and the included angle formed by the two support arms 20b is approximately 180°, which is beneficial to the smooth rotation of the cleaning ribbed disc 20. The first cleaning part 21 is provided on the first surface 205 of both support arms 20b, and the second cleaning part 22 is provided on the second surface 206 of one of the support arms 20b.

[0125] Exemplarily, the support arm 20b includes three, and the three support arms 20b are connected to the central seat 20a. The included angle formed by the three support arms 20b is approximately 120°, which is beneficial to the smooth rotation of the cleaning ribbed disc 20. The first cleaning part 21 is provided on the first surface 205 of all three support arms 20b, and the second cleaning part 22 is provided on the second surface 206 of two of the support arms 20b.

[0126] Exemplarily, the support arm 20b includes four, and the four support arms 20b are connected to the central seat 20a. The included angle formed by the four support arms 20b is approximately 90°, which is beneficial to the smooth rotation of the cleaning ribbed disc 20. The first cleaning part 21 is provided on the first surface 205 of all four support arms 20b, and the second cleaning part 22 is provided on the second surface 206 of three of the support arms 20b.

[0127] It should be noted that the number of the support arms 20b and the number of the second cleaning parts 22 described above are only for exemplary illustration. In actual applications, the number of the support arms 20b and the number of the second cleaning parts 22 can be adaptively configured according to the design requirements, and are not limited to the above limitations.

[0128] Please refer to Figure 2 and Figure 8 , in some embodiments, a first groove 211 is formed on the surface of the first cleaning part 21 for contacting the cleaning member 2002. The first groove 211 is used to receive the cleaning liquid flowing out of the liquid supply channel. When the cleaning member 2002 is supported on the cleaning ribbed disc 20 and rotates relative to the cleaning ribbed disc 20, the cleaning liquid in the first groove 211 contacts the cleaning member 2002 to wet the cleaning member 2002.

[0129] Exemplarily, the first groove 211 is formed by the depression of the surface of the first surface 205, and the first groove 211 extends to the first end 201 and the second end 202.

[0130] Exemplarily, when the cleaning member 2002 is supported on the cleaning ribbed disc 20, a part of the cleaning member 2002 is located in the first groove 211, which is convenient for the cleaning liquid to wet the cleaning member 2002 and improves the cleaning effect on the cleaning member 2002.

[0131] In some embodiments, when the cleaning ribbed disc 20 is in the first stop state or the second stop state, the liquid injection port 101 is opposite to the first groove 211 and is in fluid communication.

[0132] Exemplarily, when the cleaning member 2002 drives the cleaning rib plate 20 to rotate a preset angle and the cleaning member 2002 is in the first stop state or the second stop state, at this time, the first groove 211 is opposite to the liquid injection port 101, and the cleaning liquid flows from the liquid injection port 101 into the first groove 211.

[0133] Exemplarily, the time for rotating the cleaning rib plate 20 from the first stop state to the second stop state is set to a fixed time, such as 10S. When the cleaning rib plate 20 is in the first stop state, after the fixed time, the liquid supply device starts to supply liquid, so that the cleaning liquid accurately flows from the liquid injection port 101 into the first groove 211. During the rotation of the cleaning rib plate 20, the liquid supply device starts to supply liquid so that the cleaning liquid accurately flows from the liquid injection port 101 into the first chamber 11a. It should be noted that when the rotation speed of the cleaning member 2002 is determined, theoretically, the time consumed for the cleaning member 2002 to drive the cleaning rib plate 20 to rotate from one stop state to another stop state is constant, such as 10s. In the embodiment of the present application, timing starts only when the cleaning rib plate 20 is in the stop state, rather than when the cleaning robot 2000 docks on the base station main body 1001. The reason is that when the cleaning robot 2000 enters the docking position of the base station main body 1001, the state and position of the cleaning rib plate 20 are not determined at this time. Therefore, if timing starts from this time, such as 10s, after reaching 10s, the cleaning rib plate 20 may still be in a state where it can continue to rotate in the original direction, or the cleaning rib plate 20 may have already stopped rotating. If the liquid injection port 101 is controlled to inject liquid at this time, it may not be possible to inject it into the first groove 211, resulting in a poor self-cleaning effect of the base station, or the liquid injection timing into the first groove 211 may be too late, resulting in low self-cleaning efficiency of the base station. In the embodiment of the present application, timing starts when the cleaning rib plate 20 is in the stop state. When the set duration is reached, it means that the cleaning rib plate 20 has reached another stop state, and the first groove 211 should just be opposite to the liquid injection port 101. At this time, the liquid injection port 101 can be controlled to inject liquid, so as to effectively improve the self-cleaning effect and efficiency of the base station. Moreover, this implementation method does not require setting additional sensors and can utilize the timer of the cleaning base itself, which is beneficial to controlling the overall cost of the machine.

[0134] It should be noted that the stop state in the embodiment of the present application refers to the state where the cleaning rib plate 20 cannot continue to rotate in the original direction even under the action of an external force due to structural limitations.

[0135] Exemplarily, in another embodiment, the chassis 10 is provided with a position sensor. The position of the cleaning rib plate 20 in the first stop state or the second stop state is detected by the position sensor, so that the cleaning liquid accurately flows from the liquid injection port 101 into the first groove 211.

[0136] In some embodiments, the cleaning rib disk 20 includes a rotation center, and a first opening 212 is provided at one end of the cleaning rib disk 20 away from the rotation center, and the first opening 212 communicates with the first groove 211.

[0137] Exemplarily, the first opening 212 is provided at the second end 202 of the support arm 20b. When the cleaning member 2002 is in the first stop state or the second stop state, the support arm 20b is located at the position of the liquid injection port 101, so that the first groove 211 faces the liquid injection port 101, and the cleaning liquid flows from the liquid injection port 101 through the first opening 212 into the first groove 211. Moreover, the liquid in the first groove 211 can also be thrown into the chassis 10 from the first opening 212 under the action of centrifugal force when the cleaning rib disk 20 rotates, so as to wash the chassis 10, which is beneficial to improving the cleaning effect of the chassis 10.

[0138] In some embodiments, the first groove 211 extends in a direction from the rotation center of the cleaning rib disk 20 to a direction away from the rotation center of the cleaning rib disk 20. The first cleaning portion 21 includes bump points 213, and the bump points 213 are at least located on both sides in the width direction of the first groove 211. The bump points 213 increase the friction between the cleaning member 2002 and the first cleaning portion 21, which is beneficial to improving the cleaning effect of the first cleaning portion 21 on the cleaning member 2002.

[0139] Exemplarily, the first groove 211 extends along the length direction of the support arm 20b, and the bump points 213 are located on both sides in the width direction of the first groove 211 and extend along the extending direction of the first groove 211, increasing the contact area between the bump points 213 and the cleaning member 2002, which is beneficial to improving the cleaning effect of the first cleaning portion 21 on the cleaning member 2002.

[0140] Exemplarily, some of the bump points 213 are located on both sides in the width direction of the first groove 211, and some of the bump points 213 are located in the first groove 211 and protrude from the first groove 211. The bump points 213 located in the first groove 211 are separated from the inner wall of the first groove 211, so that the first groove 211 is satisfied to receive the cleaning liquid flowing out of the liquid supply channel, and the contact area between the bump points 213 and the cleaning member 2002 is increased, which is beneficial to improving the cleaning effect of the first cleaning portion 21 on the cleaning member 2002.

[0141] In some embodiments, the second cleaning portion 22 includes a first scraping strip 221. The first scraping strip 221 is connected to the second surface 206 of the support arm 20b, and the first scraping strip 221 contacts the first bottom wall 11. During the rotation of the support arm 20b, the first scraping strip 221 rubs on the first bottom wall 11 and cleans the first bottom wall 11.

[0142] In some embodiments, the first scraping strip 221 has elasticity, reducing the damage to the first bottom wall 11 by the first scraping strip 221 during the cleaning process.

[0143] Exemplarily, the material of the first scraping strip 221 includes rubber.

[0144] In some embodiments, the locus formed by the first scraping strip 221 rotating one week defines a second rotation circle, and the range of the minimum distance h2 between any point on the edge of the second rotation circle and the first side wall 12 is h2 ≤ 0.8 cm, which is beneficial to reducing the cleaning blind area of the first scraping strip 221 for cleaning the first bottom wall 11 and improving the overall cleaning effect.

[0145] Exemplarily, h2 can be any one of 0.1 cm, 0.2 cm, 0.3 cm, 0.4 cm, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm or the range composed of any two of them.

[0146] In some embodiments, as Figure 7 shown, the cleaning rib disk 20 further includes a second scraping strip 23, and the second scraping strip 23 is connected to one end of the support arm 20b away from the central seat 20a, and the second scraping strip 23 contacts the first side wall 12.

[0147] Exemplarily, the second scraping strip 23 is connected to the second end 202 of the support arm 20b. During the rotation of the support arm 20b, the second scraping strip 23 rubs on the first side wall 12 and cleans the first side wall 12.

[0148] In some embodiments, the second scraping strip 23 contacts the second side wall 12b. During the rotation of the support arm 20b, the second scraping strip 23 rubs on the second side wall 12b and cleans the second side wall 12b, improving the overall cleaning effect.

[0149] In some embodiments, the second scraping strip 23 has elasticity, reducing the damage to the first side wall 12 during the cleaning process by the second scraping strip 23.

[0150] Exemplarily, the material of the second scraping strip 23 includes rubber.

[0151] Please refer to Figures 10 to 13 , in some embodiments, the limiting component 30 includes a connecting piece 31, a rotating piece 32 and a limiting piece 33. The connecting piece 31 connects the rotating piece 32 and the cleaning rib disk 20. The rotating piece 32 is rotatably arranged on the chassis 10, the rotation axis of the rotating piece 32 extends along the vertical direction, the connecting piece 31 is circumferentially fixed to the rotating piece 32, and the limiting piece 33 is movably arranged on the chassis 10.

[0152] Exemplarily, the rotating piece 32 is arranged in the mounting opening 103, one end of the connecting piece 31 is connected to the rotating piece 32, and the other end protrudes from the second extending wall 1042 and is connected to the second connecting recess 204 of the central seat 20a.

[0153] In some embodiments, the rotating member 32 is provided with a spiral groove 321, the limiting member 33 extends into the spiral groove 321, and the spiral groove 321 is provided with a first stop 321a and a second stop 321b. When the limiting member 33 is located at the first stop 321a, the cleaning rib disk 20 is in the first stop state, and when the limiting member 33 is located at the second stop 321b, the cleaning rib disk 20 is in the second stop state.

[0154] In some embodiments, the rotating member 32 includes an integrally formed first connecting portion 32a and a second connecting portion 32b. The first connecting portion 32a is fixed to the connecting member 31, and the limiting member 33 is provided on the second connecting portion 32b. A spirally arranged rotating arm 322 is provided in the second connecting portion 32b, and a spiral groove 321 is formed between adjacent rotating arms 322.

[0155] In some embodiments, the rotating member 32 includes a first stop block 323 and a second stop block 324. The first stop block 323 is located at the end near the center of the spiral groove 321 and forms the first stop 321a, and the second stop block 324 is located at the starting end far from the center of the spiral groove 321 and forms the second stop 321b.

[0156] Exemplarily, the first stop block 323 is connected to the end of the rotating arm 322 near the center of the spiral groove 321, and the second stop block 324 is connected to the adjacent rotating arm 322.

[0166] Exemplarily, the sliding portion 331 is a rectangular body, and the limiting portion 332 is a cylinder.

[0167] Please refer to Figure 14 and Figure 15, in some other embodiments, the limiting component 30 includes a connecting member 31, a rotating member 32, and a limiting member 33.

[0168] Exemplarily, the limiting member 33 includes a connecting rope. One end of the connecting rope is fixed to the connecting member 31, and the other end is fixed to the inner wall of the rotating member 32 facing the connecting member 31. When the cleaning rib disk 20 rotates, it drives the rotating member 32 to rotate relative to the connecting member 31, causing the connecting rope to wind around the connecting member 31. After a predetermined number of turns, the connecting rope restricts the rotating member 32 from continuing to rotate, and thus the cleaning rib disk 20 stops rotating, that is, it is in the first stop state. When the cleaning rib disk 20 rotates in the reverse direction, it drives the rotating member 32 to rotate relative to the connecting member 31, causing the connecting rope to loosen from the connecting member 31. After a predetermined number of turns, the connecting rope winds around the connecting member 31 in the reverse direction, and the connecting rope restricts the rotating member 32 from continuing to rotate, and thus the cleaning rib disk 20 stops rotating, that is, it is in the second stop state.

[0170] Step 1: After the cleaning member 2002 rotates along the first direction S and drives the cleaning rib disk 20 to rotate relative to the chassis 10 to the first stop state, start timing in response to the cleaning member 2002 starting to rotate along the second direction N;

[0171] Step 2: Control the liquid supply device to supply liquid after the timing duration reaches the preset duration.

[0172] In some embodiments, the preset duration is the time for the cleaning rib disk 20 to rotate from the first stop state to the second stop state, or the time for the cleaning rib disk 20 to rotate from the second stop state to the first stop state.

[0173] Exemplarily, set the time for the cleaning rib disk 20 to rotate from the first stop state to the second stop state as a fixed time. When the cleaning rib disk 20 is in the first stop state, after the fixed time, the cleaning rib disk 20 rotates to the second stop state, and at this time, the first groove 211 and the liquid injection port 101 are opposite. The liquid supply device starts to supply liquid, so that the cleaning liquid accurately flows from the liquid injection port 101 into the first groove 211.

[0174] In some other embodiments, after the cleaning rib disk 20 stays for a predetermined time, the cleaning liquid is injected into the first groove 211 of the cleaning rib disk 20 through the liquid injection port 101.

[0175] Exemplarily, after the cleaning rib disk 20 stops and stays for a predetermined time, for example, 2 s, the cleaning rib disk 20 stably stays in the first stop state or the second stop state. At this time, the liquid injection port 101 of the first groove 211 is opposite, and the liquid supply device starts to supply liquid, so that the cleaning liquid accurately flows from the liquid injection port 101 into the first groove 211.
