[0053] The following specific embodiments will further illustrate this disclosure in conjunction with the above-described accompanying drawings. Detailed Implementation

[0054] The technical solutions of the present disclosure will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments.

[0055] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0058] The following detailed description of some embodiments of this disclosure is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0059] Please see Figure 1 and Figure 2 One 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 body 1001, and the bottom of the base station body 1001 has a docking position 1002 for a cleaning robot 2000 to dock.

[0060] In some embodiments, the cleaning robot 2000 includes a main body 2001 and a cleaning component 2002 rotatably disposed on the main body 2001. The cleaning component 2002 is used to mop the surface to be cleaned. The cleaning component 2002 is disposed at the bottom of the cleaning robot 2000. Exemplarily, the cleaning component 2002 is a rotary mop, and there are two cleaning components 2002 arranged side-by-side at the rear of the cleaning robot 2000. During operation, the cleaning robot 2000 can move within a designated area, while the cleaning component 2002 rotates. Thus, the cleaning robot 2000 can wipe and absorb dirt in the area it passes through, achieving a surface cleaning effect.

[0061] It is understood that the dirt mentioned in this disclosure can be sewage, filth, etc. Sewage can be liquid water or a mixture of liquid water and some filth, etc., which can be wiped or absorbed by a mop; filth can be solids such as hair, lint, and mud, or a mixture of solids and some liquid water, etc., which can be vacuumed away.

[0062] Please see Figure 2 and Figure 3 In some embodiments, the cleaning device 100 includes a chassis 10 and a cleaning rib plate 20. The chassis 10 is disposed at the docking position 1002 of the base station body 1001. The cleaning rib plate 20 is rotatably disposed on the chassis 10. The top of the cleaning rib plate 20 is provided with a first cleaning part 21, which is used for frictional contact with the cleaning component 2002 of the cleaning robot 2000. The bottom of the cleaning rib plate 20 is provided with a second cleaning part 22, which is used for contact with the chassis 10.

[0063] For example, after the cleaning rib plate 20 is installed on the chassis 10, the second cleaning part 22 makes frictional contact with the chassis 10.

[0064] For example, when the cleaning robot 2000 is in the docking position 1002, the first cleaning part 21 makes frictional contact with the cleaning component 2002.

[0065] In some embodiments, the cleaning apparatus 100 includes a limiting component 30. The limiting component 30 is connected to the chassis 10 and / or the cleaning rib plate 20. The limiting component 30 prevents the cleaning rib plate 20 from continuing to rotate after rotating a preset angle relative to the chassis 10 along a preset direction. The angle through which the cleaning rib plate 20 rotates from a first stop state to a second stop state along the preset direction is greater than or equal to 360°. When the cleaning member 2002 is supported on and rotates on the cleaning rib plate 20, and the cleaning rib plate 20 is in a stopped rotation state relative to the chassis 10, the cleaning member 2002 is cleaned by the first cleaning section 21. When the cleaning rib plate 20 is rotating relative to the chassis 10, the chassis 10 is cleaned by the second cleaning section 22.

[0066] This disclosure utilizes the cleaning component 2002 to drive the cleaning rib plate 20, enabling the second cleaning section 22 to clean the chassis 10. When the cleaning rib plate 20 is in a stopped rotating state, the cleaning component 2002 rotates relative to the first cleaning section 21, causing the first cleaning section 21 to clean the cleaning component 2002. This cleans both the chassis 10 and the cleaning component 2002 together, reducing dirt residue on the chassis 10. Furthermore, the cleaning rib plate 20 rotates at an angle greater than or equal to 360°, ensuring that the cleaning rib plate 20 completes at least one revolution on the chassis 10. This effectively reduces blind spots in cleaning, improves the cleaning effect, further reduces dirt residue on the chassis 10, reduces the user's workload, and enhances the user experience.

[0067] Please see Figure 4 In some embodiments, the cleaning component 2002 rotates along the first direction S, causing the cleaning rib plate 20 to rotate relative to the chassis 10 to clean the chassis 10, until the cleaning rib plate 20 stops rotating under the action of the limiting component 30 after rotating at a preset angle, and the cleaning component 2002 continues to rotate along the first direction S to clean the cleaning component 2002.

[0068] In some embodiments, the cleaning component 2002 can rotate along the second direction N, causing the cleaning rib plate 20 to rotate relative to the chassis 10 to clean the chassis 10, until the cleaning rib plate 20 stops rotating under the action of the limiting component 30 after rotating a preset angle. The cleaning component 2002 then continues to rotate along the second direction N to clean itself. The first direction S is opposite to the second direction N. The first direction S is one of clockwise and counterclockwise directions, and the second direction N is the other.

[0069] For example, when the cleaning robot 2000 enters the cleaning base station 1000 to perform a cleaning operation, the first direction S is clockwise and the second direction N is counterclockwise. The cleaning component 2002 rotates clockwise, causing the cleaning rib plate 20 to rotate relative to the chassis 10 to clean the chassis 10, until the cleaning rib plate 20 stops rotating under the action of the limiting component 30 after rotating a preset angle. The cleaning component 2002 then continues to rotate clockwise to clean itself. After the cleaning component 2002 rotates clockwise relative to the cleaning rib plate 20 a predetermined number of times, the cleaning component 2002 rotates counterclockwise, causing the cleaning rib plate 20 to rotate relative to the chassis 10 to clean itself, until the cleaning rib plate 20 stops rotating under the action of the limiting component 30 after rotating a preset angle. The cleaning component 2002 then continues to rotate counterclockwise to clean itself. This cycle is repeated to clean both the cleaning component 2002 and the chassis 10.

[0070] For example, when the cleaning robot 2000 enters the cleaning base station 1000 to perform a cleaning operation, the first direction S is counterclockwise and the second direction N is clockwise. The cleaning component 2002 rotates counterclockwise, causing the cleaning rib plate 20 to rotate relative to the chassis 10 to clean the chassis 10, until the cleaning rib plate 20 stops rotating under the action of the limiting component 30 after rotating at a preset angle. The cleaning component 2002 continues to rotate counterclockwise to clean itself. During this process, dirt generated by cleaning the cleaning component 2002 will remain on the chassis 10. After the cleaning component 2002 rotates counterclockwise relative to the cleaning rib plate 20 a predetermined number of times, the cleaning component 2002 rotates clockwise in the opposite direction, causing the cleaning rib plate 20 to rotate relative to the chassis 10 and clean the chassis 10, until the cleaning rib plate 20 stops rotating under the action of the limiting component 30 after rotating at a preset angle. The cleaning component 2002 then continues to rotate clockwise to clean itself. This cycle is repeated to achieve cleaning of the cleaning component 2002 and the chassis 10.

[0071] Please see Figure 2 In some embodiments, the base station body 1001 may be provided with a liquid supply channel (not shown in the figure), which is connected to a liquid supply device. The liquid supply device is used to provide cleaning fluid, which may be water, detergent, a mixture of water and detergent, etc. During the cleaning operation, the liquid supply device can output cleaning fluid to at least one of the chassis 10 or the cleaning rib plate 20 through the liquid supply channel, so as to rinse the chassis 10 and / or the cleaning component 2002 of the cleaning robot 2000 with the cleaning fluid to achieve a better cleaning effect.

[0072] For example, when the cleaning component 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 chassis 10 through the liquid supply channel, so that the second cleaning unit 22 can clean the chassis 10.

[0073] For example, when the cleaning component 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 component 2002, so that the first cleaning unit 21 can clean the cleaning component 2002.

[0074] In some embodiments, the chassis 10 includes a liquid injection port 101, and a liquid supply channel communicates with the liquid injection port 101. The cleaning fluid is output to the chassis 10 or the cleaning rib plate 20 through the liquid injection port 101.

[0075] In some embodiments, the base station body 1001 includes the injection port 101, and the base station body 1001 directly outputs cleaning fluid to at least one of the chassis 10 or the cleaning rib plate 20 through the injection port 101.

[0076] In some embodiments, such as Figure 2 As shown, the chassis 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 and surrounds at least a portion of the edge of the first bottom wall 11 to form a first chamber 11a. A cleaning rib plate 20 is disposed in the first chamber 11a.

[0077] In some embodiments, the injection port 101 is provided on the first side wall 12, and the side of the first side wall 12 away from the first chamber 11a is provided with a connecting pipe 102 that communicates with the injection port 101, and is connected to the liquid supply channel through the connecting pipe 102.

[0078] For example, when the cleaning component 2002 is supported on the cleaning rib plate 20 and drives the cleaning rib plate 20 to rotate, cleaning fluid is output into the first chamber 11a through the liquid injection port 101. The cleaning fluid flows to various areas of the first chamber 11a under the rotation of the cleaning rib plate 20, which helps to improve the cleaning effect of the chassis 10.

[0079] In some embodiments, when the cleaning rib plate 20 is in a first stop state or a second stop state, the injection port 101 is opposite to the cleaning rib plate 20 and in fluid communication.

[0080] For example, when the cleaning component 2002 drives the cleaning rib plate 20 to rotate by a preset angle, and the cleaning component 2002 is in the first stop state or the second stop state, the cleaning rib plate 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 component 2002, the cleaning component 2002 can be moistened by the cleaning liquid injected through the liquid injection port 101.

[0081] Please see Figures 5 to 7 In some embodiments, the chassis 10 includes a sludge extraction port 13, and a portion of the first bottom wall 11 is recessed to form a second chamber 11b, which communicates with the outside of the chassis 10 through the sludge extraction port 13.

[0082] For example, 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 cleaning operations, the dirt generated by the cleaning chassis 10 and the cleaning components 2002 flows into the second chamber 11b and is discharged to the outside of the chassis 10 through the sludge extraction port 13. For example, it is discharged into the wastewater tank of the cleaning base station connected to the sludge extraction port 13, or through a drain pipe connected to the outside of the cleaning base station 1000.

[0083] For example, the sludge suction port 13 is located at the lowest point of the second chamber 11b, which facilitates the flow of dirt to the sludge suction port 13 under the action of gravity, reduces the risk of dirt accumulating on the second chamber 11b and causing blockage, and makes it easier to discharge dirt.

[0084] In some embodiments, a filter device 14 covers the second chamber 11b, and the first chamber 11a and the second chamber 11b are connected through the filter device 14. The filter device 14 is used at least to filter sewage from dirt, prevent solid waste from entering the second chamber 11b, and reduce the risk of clogging of the sludge suction port 13.

[0085] For example, when the cleaning rib plate 20 is rotating relative to the chassis 10, the dirt generated by the second cleaning section 22 in cleaning the first chamber 11a enters the second chamber 11b through the filter device 14.

[0086] For example, when the cleaning rib plate 20 drives the chassis 10 to rotate, the dirt from the cleaning component 2002 cleaned by the first cleaning part 21 falls into the first chamber 11a. When the cleaning rib plate 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 component 2002 enter the second chamber 11b through the filter device 14.

[0087] In some embodiments, the filter device 14 has a first filter mesh portion 141, which is used at least to filter wastewater from dirt. Exemplarily, there are multiple first filter mesh portions 141, which are spaced apart and distributed on the filter device 14. During the cleaning process, solid waste in the dirt is filtered out by the first filter mesh portions 141 and remains on the filter device 14.

[0088] It is understood that the inner diameter and shape of the first filter mesh portion 141 can be configured according to the type of dirt. For example, the first filter mesh portion 141 can be circular or elongated, and this disclosure does not limit it.

[0089] It is worth noting that during the filtration process of the first filter mesh portion 141, some small dirt may pass through the first filter mesh portion 141 and be discharged into the second chamber 11b. Such dirt can be discharged through the sewage outlet 13 or manually cleaned. This disclosure does not impose any restrictions on this.

[0090] In some embodiments, the filter device 14 includes a second bottom wall 14a connected to a first bottom wall 11, and a first filter mesh portion 141 penetrates the second bottom wall 14a along the thickness direction of the second bottom wall 14a.

[0091] In some embodiments, the filtration device 14 includes a second sidewall 14b and a second filter mesh portion 142, the second sidewall 14b connecting the first sidewall 12 and the second bottom wall 14a. The second filter mesh portion 142 extends through the second sidewall 14b along its thickness direction. During the rotation of the cleaning rib plate 20 driven by the cleaning member 2002, some dirt is discharged through the second filter mesh portion 142 into the second chamber 11b. Because the second filter mesh portion 142 is located on the second sidewall 14b, dirt is less likely to accumulate on the second sidewall 14b, which helps improve the drainage efficiency.

[0092] For example, there are multiple second filter mesh portions 142, and the multiple second filter mesh portions 142 are spaced apart on the second sidewall 14b.

[0093] It is understood that the inner diameter and shape of the second filter mesh portion 142 can be configured according to the type of dirt. For example, the second filter mesh portion 142 can be circular or elongated, and this disclosure does not limit it.

[0094] In some embodiments, the area of ​​a single mesh opening in the second filter mesh portion 142 is larger than the area of ​​a single mesh opening in the first filter mesh portion 141. This provides at least the following effects: Firstly, lint and debris falling from the cleaning component 2002 will clump together due to the scraping action of the cleaning ribs 20. This clump of debris is larger, and the second filter mesh portion 142 allows the larger clumps of lint and debris to be discharged into the lower second chamber 11b. The lint in the second chamber 11b is then dispersed and broken up by the water flow, allowing it to be removed by the suction port 13. Secondly, the second filter mesh portion 142 can block larger debris, such as screws and building blocks. The cooperation between the first filter mesh portion 141 and the second filter mesh portion 142 further improves the wastewater discharge effect and efficiency of the cleaning device.

[0095] In some embodiments, the filter device 14 is detachably connected to the chassis 10 for easy disassembly for replacement or cleaning. Detachable connection methods include, but are not limited to, snap-fit, bolt-fit, and interference fit.

[0096] In some embodiments, the range of rotation of the cleaning rib plate 20 relative to the chassis 10 extends through the area where the first filter mesh portion 141 is located.

[0097] For example, during the rotation of the cleaning rib plate 20 driven by the cleaning component 2002, the cleaning rib plate 20 cleans the first chamber 11a. While carrying 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 become clogged. This helps to improve the filtration efficiency and sewage discharge efficiency of the first filter mesh portion 141 and improve the overall cleaning effect.

[0098] Please see Figure 4 In some embodiments, the cleaning ribs 20 include two ribs 20, which are arranged along the left-right direction of the chassis 10, and the filter device 14 is disposed between the two cleaning ribs 20. The range of rotation of the two cleaning ribs 20 relative to the chassis 10 passes through the area where the first filter mesh portion 141 is located, further improving the cleaning effect on the first chamber 11a and the first filter mesh portion 141. The left-right direction is the direction perpendicular to the direction in the horizontal plane where the cleaning robot 200 enters and exits the cleaning base station 1000.

[0099] In some embodiments, the two first rotating circles formed by the rotation of the two cleaning ribs 20 are tangent or intersecting. This reduces the cleaning blind zone between the two cleaning ribs 20 on the chassis 10, improving the cleaning effect on the chassis 10. Furthermore, the intersecting or tangent area may be located in the area where the first filter mesh portion 141 is located. This allows the cleaning ribs 20 to clean a larger area of ​​the first filter mesh portion 141, achieving better cleaning of the first filter mesh portion 141. Even further, the area where the first filter mesh portion 141 is located is within the area traversed by the rotation of the two first rotating circles. This ensures that the cleaning area of ​​the two cleaning ribs 20 completely covers 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.

[0100] For example, when the two first rotating circles formed by the rotation of the two cleaning ribs 20 are tangent to each other, the area where the two first rotating circles are located completely covers the area where the first filter mesh portion 141 is located.

[0101] For example, when the two first rotating circles formed by the rotation of the two cleaning ribs 20 intersect, during the process of the two cleaning ribs 20 rotating one revolution, each cleaning rib 20 cleans the area where the first filter mesh portion 141 is located within the area where the two first rotating circles intersect, which helps to improve the cleaning effect of the area.

[0102] In some embodiments, a first filter mesh portion 141 is disposed between two cleaning ribs 20, and the first filter mesh portion 141 is symmetrically arranged about the center line in the left-right direction of the base 10. During the rotation of the cleaning ribs 20, it makes uniform contact with the filter 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 ribs 20, and reducing missed areas. The symmetrical first filter mesh portion 141 ensures more even distribution of liquid as it passes through the filter device 14, which helps prevent local clogging and improves filtration efficiency.

[0103] In some embodiments, the trajectory of the cleaning rib disc 20 rotating one revolution forms a first rotation circle. The minimum distance h1 between any point on the edge of the first rotation circle and the first sidewall 12 is defined as h1≤1cm. If h1 is greater than 1cm, the cleaning blind spot of the cleaning rib disc 20 in cleaning the first bottom wall 11 becomes larger, affecting the cleaning of the chassis 10. By limiting h1≤1cm, it is beneficial to reduce the cleaning blind spot of the cleaning rib disc 20 in cleaning the first bottom wall 11 and improve the overall cleaning effect.

[0104] For example, h1 can be any one or any two of 0.1cm, 0.2cm, 0.3cm, 0.4cm, 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, and 1.0cm.

[0105] 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 cleaning rib plate 20 is in the same position 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 cleaning fluid into the cleaning rib plate 20 through the injection port 101.

[0106] In some embodiments, n≥2, the cleaning rib disc 20 rotates at least two revolutions from the first stop state to the second stop state. Increasing the number of rotations of the cleaning rib disc 20 is beneficial to improving the cleaning effect of the cleaning rib disc 20 on the chassis 10.

[0107] Please see Figures 7 to 10 In some embodiments, the cleaning rib plate 20 includes a central seat 20a and at least two support arms 20b. A first end 201 of each support arm 20b is fixedly connected to the central seat 20a, and a second end 202 of each support arm 20b is located away from the central seat 20a. The support arm 20b rotates with the central seat 20a. The central seat 20a is connected to the chassis 10.

[0108] In some embodiments, the chassis 10 has a connecting seat 15, and the center seat 20a is circumferentially fixedly connected to the connecting seat 15.

[0109] In some embodiments, the chassis 10 includes a mounting opening 103 that extends through the first bottom wall 11 along its thickness direction. An extension wall 104 is provided at the edge of the mounting opening 103 within the first chamber 10a. At least a portion of this extension wall 104 forms a connecting seat 15.

[0110] For example, such as Figure 10As shown, the extension wall 104 includes a first extension wall 1041 and a second extension wall 1042. The first extension wall 1041 connects to the edge of the mounting opening 103, and the second extension wall 1042 connects to the side of the first extension wall 1041 facing 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 lies within the projection of the first extension wall 1041. The center seat 20a has a first connecting recess 203, and the second extension wall 1042 is disposed within the first connecting recess 203. Exemplarily, the center seat 20a is clearance-fitted with the first extension wall 1041 and the second extension wall 1042 to reduce friction between the center seat 20a and the first and second extension walls 1041 during rotation.

[0111] Optionally, the extension wall 104 includes a first extension wall 1041, which connects to the edge of the mounting port 103. The center seat 20a has a first connecting recess 203, and the first extension wall 1041 is disposed in the first connecting recess 203. The center seat 20a and the first extension wall 1041 are in clearance fit to reduce the friction between the center seat 20a and the first extension wall 1041 during rotation.

[0112] In some embodiments, the limiting component 30 is connected to the chassis 10 through the mounting port 103 and partially protrudes from the extension wall 104. The center seat 20a is connected to the portion of the limiting component 30 that protrudes from the extension wall 104. The portion of the limiting component 30 that protrudes from the extension wall 104 is connected to the center seat 20a, so that the center seat 20a and the limiting component 30 can be relatively fixed, thereby allowing the center seat 20a and the extension wall 104 to have a clearance fit.

[0113] For example, the center seat 20a has a second connecting recess 204, the first connecting recess 203 and the second connecting recess 204 have the same center, the outer diameter of the second connecting recess 204 is smaller than the outer diameter of the first connecting recess 203, and the portion of the limiting component 30 protruding from the extension wall 104 is disposed in the second connecting recess 204. The portion of the limiting component 30 protruding from the extension wall 104 is held in the second connecting recess 204 by means of snap-fit ​​or interference fit.

[0114] For example, when the cleaning component 2002 drives the cleaning rib plate 20 to rotate, the center seat 20a drives the limiting component 30 to rotate. After the cleaning rib plate 20 rotates by a preset angle, the limiting component 30 restricts the rotation of the center seat 20a.

[0115] In some embodiments, the limiting component 30 is disposed between the connecting seat 15 and the center seat 20a. The projection of the limiting component 30 on the upper surface of the first bottom wall 11 is located within the range of the center seat 20a. This allows the limiting component 30 to not affect the cleaning range of the support arm 20b on the chassis 10, reducing the cleaning blind spot and improving the overall cleaning effect.

[0116] 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 a first cleaning part 21 is located on the first surface 205. The second surface 206 faces the first bottom wall 11, and a second cleaning part 22 is located on the second surface 206.

[0117] In some embodiments, at least one support arm 20b has a second cleaning section 22 on its second surface 206.

[0118] In some embodiments, a plurality of support arms 20b are spaced apart along the circumferential direction of the central seat 20a.

[0119] For example, the support arm 20b includes two arms, and the included angle between the two support arms 20b is approximately 180°, which is beneficial for the smooth rotation of the cleaning rib plate 20. The first surface 205 of both support arms 20b is provided with a first cleaning part 21, and the second surface 206 of one of the support arms 20b is provided with a second cleaning part 22.

[0120] For example, the support arm 20b includes three arms, which are connected to the central seat 20a. The included angle formed by the three support arms 20b is approximately 120°, which is beneficial for the smooth rotation of the cleaning rib plate 20. The first surface 205 of each of the three support arms 20b is provided with a first cleaning part 21, and the second surface 206 of two of the support arms 20b is provided with a second cleaning part 22.

[0121] For example, the support arm 20b includes four arms, which are connected to the center seat 20a. The included angle formed by the four support arms 20b is approximately 90°, which is beneficial for the smooth rotation of the cleaning rib plate 20. The first surface 205 of each of the four support arms 20b is provided with a first cleaning part 21, and the second surface 206 of three of the support arms 20b is provided with a second cleaning part 22.

[0122] It is worth noting that the number of support arms 20b and the number of second cleaning units 22 mentioned above are only illustrative examples. In actual applications, the number of support arms 20b and the number of second cleaning units 22 can be adapted to design requirements and are not limited to the above limitations.

[0123] Please see Figure 2 and Figure 8 In some embodiments, a first groove 211 is formed on the surface of the first cleaning section 21 that is in contact with the cleaning component 2002. The first groove 211 is used to receive the cleaning fluid flowing out of the liquid supply channel. When the cleaning component 2002 is supported on the cleaning rib plate 20 and rotates relative to the cleaning rib plate 20, the cleaning fluid in the first groove 211 comes into contact with the cleaning component 2002 to wet the cleaning component 2002.

[0124] For example, the surface of the first surface 205 is recessed to form a first groove 211, which extends to the first end 201 and the second end 202.

[0125] For example, when the cleaning component 2002 is supported on the cleaning rib plate 20, a portion of the cleaning component 2002 is located in the first groove 211, which facilitates the cleaning liquid to wet the cleaning component 2002 and improves the cleaning effect on the cleaning component 2002.

[0126] In some embodiments, when the cleaning rib plate 20 is in a first stop state or a second stop state, the liquid injection port 101 is opposite to the first groove 211 and in fluid communication.

[0127] For example, when the cleaning component 2002 drives the cleaning rib plate 20 to rotate by a preset angle, and the cleaning component 2002 is in a first stop state or a second stop state, 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.

[0128] For example, the time for the cleaning rib plate 20 to rotate from a first stop state to a second stop state is set to a fixed time, such as 10 seconds. When the cleaning rib plate 20 is in the first stop state, after the fixed time, the liquid supply device starts supplying liquid, so that the cleaning liquid flows accurately from the injection port 101 into the first groove 211. During the rotation of the cleaning rib plate 20, the liquid supply device starts supplying liquid, so that the cleaning liquid flows accurately from the injection port 101 into the first chamber 11a. It should be noted that, given a fixed rotation speed of the cleaning component 2002, theoretically, the time taken for the cleaning component 2002 to drive the cleaning rib plate 20 to rotate from one stop state to another stop state is constant, for example, 10 seconds. In this embodiment, timing begins only when the cleaning rib plate 20 is in a stop state, rather than when the cleaning robot 2000 docks on the base station body 1001. The reason is that when the cleaning robot 2000 enters the docking position of the base station body 1001, the state and position of the cleaning rib plate 20 are uncertain. Therefore, if timing starts from this point, for example, 10 seconds, after 10 seconds, the cleaning rib plate 20 may still be able to continue rotating in its original direction, or it may have already stopped rotating. If the liquid injection port 101 is controlled to inject liquid at this time, it may not be able to inject into the first groove 211, resulting in poor self-cleaning effect of the base station. Alternatively, the liquid injection into the first groove 211 may be too late, leading to low self-cleaning efficiency. In this embodiment, timing starts from when the cleaning rib plate 20 is in a stopped state, and continues until the set time is reached. This indicates that the cleaning rib plate 20 has reached another stopped state, and the first groove 211 should be exactly opposite the liquid injection port 101. At this time, the liquid injection port 101 can be controlled to inject liquid, thus effectively improving the self-cleaning effect and efficiency of the base station. Furthermore, this implementation method does not require additional sensors and can utilize the timer of the cleaning base station itself, which helps control the overall cost.

[0129] It should be noted that the "stopped state" in this embodiment refers to the state in which the cleaning rib plate 20 is unable to continue rotating in the original direction due to structural limitations, even under the action of external force.

[0130] For example, in another embodiment, the chassis 10 is provided with a position sensor, which detects the position of the cleaning rib plate 20 in the first stop state or the second stop state, so that the cleaning fluid flows accurately from the injection port 101 into the first groove 211.

[0131] In some embodiments, the cleaning rib disc 20 includes a rotation center, and a first opening 212 is provided at one end of the cleaning rib disc 20 away from the rotation center. The first opening 212 communicates with a first groove 211.

[0132] For example, the first opening 212 is located at the second end 202 of the support arm 20b. When the cleaning component 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 is opposite to the liquid injection port 101. The cleaning fluid flows from the liquid injection port 101 through the first opening 212 into the first groove 211. Furthermore, 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 plate 20 rotates, so as to rinse the chassis 10 and improve the cleaning effect of the chassis 10.

[0133] In some embodiments, the first groove 211 extends in a direction from the rotation center of the cleaning rib 20 to a direction away from the rotation center of the cleaning rib 20. The first cleaning portion 21 includes protrusions 213, which are located at least on both sides in the width direction of the first groove 211. The protrusions 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.

[0134] For example, the first groove 211 extends along the length direction of the support arm 20b, and the protrusion 213 is located on both sides of the width direction of the first groove 211 and extends along the extension direction of the first groove 211, increasing the contact area between the protrusion 213 and the cleaning component 2002, which is beneficial to improving the cleaning effect of the first cleaning part 21 on the cleaning component 2002.

[0135] For example, some of the protrusions 213 are located on both sides of the width direction of the first groove 211, and some of the protrusions 213 are located inside the first groove 211 and protrude from the first groove 211. The protrusions 213 located inside the first groove 211 are separated from the inner wall of the first groove 211, so that the first groove 211 can receive the cleaning liquid flowing out of the liquid supply channel and increase the contact area between the protrusions 213 and the cleaning component 2002, which is beneficial to improving the cleaning effect of the first cleaning part 21 on the cleaning component 2002.

[0136] In some embodiments, the second cleaning unit 22 includes a first scraper 221 connected to the second surface 206 of the support arm 20b, and the first scraper 221 contacts the first bottom wall 11. During the rotation of the support arm 20b, the first scraper 221 rubs against the first bottom wall 11 and cleans the first bottom wall 11.

[0137] In some embodiments, the first scraper 221 is elastic, reducing damage to the first bottom wall 11 during the cleaning process.

[0138] For example, the material of the first scraper 221 includes rubber.

[0139] In some embodiments, the trajectory of the first scraper 221 rotating one revolution is defined to form a second rotation circle. The range of the minimum distance h2 between any point on the edge of the second rotation circle and the first sidewall 12 is h2≤0.8cm, which helps to reduce the cleaning blind spot of the first scraper 221 cleaning the first bottom wall 11 and improve the overall cleaning effect.

[0140] For example, h2 can be any one or any combination of 0.1cm, 0.2cm, 0.3cm, 0.4cm, 0.5cm, 0.6cm, 0.7cm, and 0.8cm.

[0141] In some embodiments, such as Figure 7 As shown, the cleaning rib plate 20 also includes a second scraper 23, which is connected to one end of the support arm 20b away from the center seat 20a, and the second scraper 23 contacts the first side wall 12.

[0142] For example, the second scraper 23 is connected to the second end 202 of the support arm 20b. During the rotation of the support arm 20b, the second scraper 23 rubs against the first sidewall 12 and cleans the first sidewall 12.

[0143] In some embodiments, the second scraper 23 contacts the second sidewall 12b. During the rotation of the support arm 20b, the second scraper 23 rubs against the second sidewall 12b and cleans the second sidewall 12b, thereby improving the overall cleaning effect.

[0144] In some embodiments, the second scraper 23 is elastic, reducing damage to the first sidewall 12 during the cleaning process.

[0145] For example, the material of the second scraper 23 includes rubber.

[0146] Please see Figures 10 to 13 In some embodiments, the limiting component 30 includes a connector 31, a rotating component 32, and a limiting component 33. The connector 31 connects the rotating component 32 and the cleaning rib plate 20. The rotating component 32 is rotatably mounted on the chassis 10, and the axis of rotation of the rotating component 32 extends in the vertical direction. The connector 31 is circumferentially fixed to the rotating component 32, and the limiting component 33 is movably mounted on the chassis 10.

[0147] For example, the rotating member 32 is disposed in the mounting port 103, one end of the connecting member 31 is connected to the rotating member 32, and the other end protrudes from the second extension wall 1042 and is connected to the second connecting recess 204 of the center seat 20a.

[0148] In some embodiments, the rotating member 32 is provided with a spiral groove 321, and the limiting member 33 extends into the spiral groove 321. 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 plate 20 is in a first stop state, and when the limiting member 33 is located at the second stop 321b, the cleaning rib plate 20 is in a second stop state.

[0149] In some embodiments, the rotating member 32 includes an integral first connecting portion 32a and a second connecting portion 32b. The first connecting portion 32a is fixed to the connecting member 31, and a limiting member 33 is disposed in the second connecting portion 32b. The second connecting portion 32b is provided with a helically arranged rotating arm 322, and a helical groove 321 is formed between adjacent rotating arms 322.

[0150] In some embodiments, the rotating member 32 includes a first stop 323 and a second stop 324. The first stop 323 is located at the tail end near the center of the spiral groove 321 and forms a first stop 321a. The second stop 324 is located at the starting end away from the center of the spiral groove 321 and forms a second stop 321b.

[0151] For example, the first stop 323 is connected to the end of the rotating arm 322 near the center of the spiral groove 321, and the second stop 324 is connected to the adjacent rotating arm 322.

[0152] In some embodiments, a first straight line P is defined, which passes through a first stop 321a, the center of the rotating member 32, and a second stop 321b. The rotation of the rotating member 32 causes the limiting member 33 to move along the first straight line P from one of the first stop 321a and the second stop 321b to the other.

[0153] For example, when the cleaning component 2002 rotates clockwise, it drives the connecting component 31 to rotate, which in turn drives the rotating component 32 to rotate. During the rotation of the rotating component 32, the rotating arm 322 pushes the limiting component 33 to move along the first straight line P from the first stop 321a to the second stop 321b, that is, the cleaning rib plate 20 rotates from the first stop state to the second stop state. When the cleaning component 2002 rotates counterclockwise, it drives the connecting component 31 to rotate, which in turn drives the rotating component 32 to rotate. During the rotation of the rotating component 32, the rotating arm 322 pushes the limiting component 33 to move along the first straight line P from the second stop 321b to the first stop 321a, that is, the cleaning rib plate 20 rotates from the second stop state to the first stop state.

[0154] In some embodiments, the limiting component 30 includes a bearing 34 located between the rotating member 32 and the extension wall 104.

[0155] For example, the bearing 34 is located between the first extension wall 1041 and the first connecting portion 32a. The bearing 34 causes the cleaning member 2002 to drive the connecting member 31 and the rotating member 32 to rotate together.

[0156] In some embodiments, such as Figure 11 As shown, the limiting component 30 includes a mounting base 30a, which is fixedly mounted on the chassis 10 and located below the rotating component 32. The mounting base 30a is provided with a sliding groove 361, which is arranged along the extension direction of the first straight line P. One end of the limiting component 33 is slidably disposed in the sliding groove 361, and the other end of the limiting component 33 extends into the spiral groove 321 of the rotating component 32.

[0157] For example, the mounting base 30a includes a cover plate 35, which connects to the side of the rotating member 32 opposite to the connecting member 31. The cover plate 35 has a through groove 351, which is provided along the extension direction of the first straight line P. The limiting member 33 passes through the through groove 351 and is located in the spiral groove 321. The through groove 351 facilitates the restriction of the movement of the limiting member 33 along the first straight line P, which is beneficial for accurately controlling the first stop state and the second stop state of the cleaning rib plate 20.

[0158] Exemplarily, the mounting base 30a also includes a base 36, which is connected to the chassis 10, and a cover plate 35 is located between the rotating member 32 and the base 36. The base 36 is provided with a groove 361, which is arranged along the extension direction of the first straight line P, and a portion of the limiting member 33 is disposed in the groove 361. The groove 361 further facilitates the restriction of the movement of the limiting member 33 along the first straight line P, which is beneficial for accurately controlling the first stop state and the second stop state of the cleaning rib plate 20.

[0159] In some embodiments, the lower surface of the first bottom wall 11 is provided with a fixing member 111, and the base 36 is connected to the fixing member 111, thereby fixing the base 36 to the chassis 10.

[0160] In some embodiments, the limiting member 33 includes a sliding part 331 and a limiting part 332. The sliding part 331 is disposed in the slide groove 361, and one end of the limiting part 332 is connected to the sliding part 331, while the other end extends out of the through groove 351 and is disposed in the spiral groove 321.

[0161] For example, the sliding part 331 is a rectangle and the limiting part 332 is a cylinder.

[0162] Please see Figure 14 and Figure 15In other embodiments, the limiting component 30 includes a connector 31, a rotating component 32, and a limiting component 33. The connector 31 is fixed to the chassis 10. The rotating component 32 is sleeved on the connector 31 and rotatably connected to the connector 31. The cleaning rib plate 20 is fixedly connected to the rotating component 32. The limiting component 33 is located between the rotating component 32 and the connector 31, with one end fixed to the connector 31 and surrounding the connector 31, and the other end fixed to the rotating component 32.

[0163] For example, the limiting member 33 includes a connecting rope, one end of which 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 plate 20 rotates, it drives the rotating member 32 to rotate relative to the connecting member 31, causing the connecting rope to wrap around the connecting member 31. After a predetermined number of turns, the connecting rope restricts the rotating member 32 from continuing to rotate, thereby stopping the cleaning rib plate 20 from rotating, i.e., it is in the first stopped state. When the cleaning rib plate 20 rotates in the opposite direction, it drives the rotating member 32 to rotate relative to the connecting member 31, causing the connecting rope to unwind from the connecting member 31. After a predetermined number of turns, the connecting rope wraps around the connecting member 31 in the opposite direction, restricting the rotating member 32 from continuing to rotate, thereby stopping the cleaning rib plate 20 from rotating, i.e., it is in the second stopped state.

[0164] In some embodiments, after the cleaning component 2002 rotates along the first direction S and drives the cleaning rib plate 20 to rotate relative to the chassis 10 to a first stop state, in response to the cleaning component 2002 starting to rotate along the second direction N, timing begins, and after the timing duration reaches a preset duration, the liquid supply device is controlled to supply liquid.

[0165] In some embodiments, the preset duration is the time it takes for the cleaning rib plate 20 to rotate from the first stop state to the second stop state, or the time it takes for the cleaning rib plate 20 to rotate from the second stop state to the first stop state.

[0166] For example, the time for the cleaning rib plate 20 to rotate from the first stop state to the second stop state is set to a fixed time. When the cleaning rib plate 20 is in the first stop state, after the fixed time, the cleaning rib plate 20 rotates to the second stop state, at which time the liquid injection port 101 of the first groove 211 is opposite. The liquid supply device starts to supply liquid, so that the cleaning liquid flows accurately from the liquid injection port 101 into the first groove 211.

[0167] In other embodiments, after the cleaning rib plate 20 has remained in place for a predetermined time, the cleaning fluid is injected into the first groove 211 of the cleaning rib plate 20 through the injection port 101.

[0168] For example, after the cleaning rib plate 20 stops, after a predetermined time, such as 2 seconds, the cleaning rib plate 20 is stably in a first stopped state or a second stopped 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 flows accurately from the liquid injection port 101 into the first groove 211.

[0169] In some embodiments, the rotational speed of the two cleaning components 2002 is controlled so that the two cleaning ribs 20 connecting the two cleaning components 2002 have different rotational speeds.

[0170] For example, by controlling the rotation speed of the two cleaning components 2002 with different motors, the rotation speed of the two cleaning ribs 20 can be controlled, thereby reducing the risk of collision between the two cleaning ribs 20.

[0171] For example, the rotational speed of the two cleaning components 2002 is controlled by a motor equipped with a differential module, thereby controlling the rotational speed of the two cleaning ribs 20 and reducing the risk of collision between the two cleaning ribs 20.

[0172] Please see Figure 1 This disclosure provides a clean base station 1000, including a base station body 1001 and a cleaning device 100 in any of the above embodiments.

The cleaning base station 1000 is used in conjunction with the cleaning robot 2000 and is at least used for maintaining the cleaning robot 2000.

[0174] In some embodiments, the cleaning robot 2000 includes a vacuuming device and a dustbin, wherein the vacuuming device's suction port is located at the bottom of the cleaning robot 2000. The dustbin is detachably disposed within the cleaning robot 2000, and the vacuuming device is connected to the dustbin. During operation, the cleaning robot 2000 can move within a designated area, while the vacuuming device sucks up dirt from the area it passes through through the suction port and collects it in the dustbin. The dirt in the dustbin can be emptied periodically.

[0175] In some embodiments, the cleaning robot 2000 includes a drive wheel 2003 and a caster wheel 2004, wherein the drive wheel 2003 and the caster wheel 2004 are both disposed at the bottom of the cleaning robot 2000, and the drive wheel 2003 and the caster wheel 2004 cooperate to support the cleaning robot 2000. The drive wheel 2003 is used to drive the cleaning robot 2000 forward or backward, and the caster wheel 2004 is used to adapt to the movement direction of the cleaning robot 2000.

[0176] For example, the cleaning robot 2000 moves in and out of the parking space 1002 in conjunction with the drive wheel 2003 and the omnidirectional wheel 2004.

[0177] For example, there are two drive wheels 2003, which are arranged side by side with intervals between them. The two drive wheels 2003 are located on the left and right sides of the cleaning robot 2000, respectively, and the omnidirectional wheel 2004 can be located on the front or rear side of the cleaning robot 2000.

[0178] It is worth noting that the above description of the cleaning robot 2000 is merely illustrative. In practical applications, the quantity, position, or selection of components such as cleaning parts 2002, drive wheels 2003, casters 2004, vacuuming devices, and dust boxes in the cleaning robot 2000 can be adaptively configured according to design requirements, and this disclosure does not impose any restrictions on this.

[0179] It should be noted that the maintenance described herein includes, but is not limited to, charging, dust collection, mop washing, drying, and pumping out wastewater and / or adding clean water to the cleaning robot 2000. This can be understood as the cleaning robot 2000 performing at least one of the following within the cleaning base station 1000: 1. Charging the cleaning robot 2000; 2. Recycling the debris from the cleaning robot 2000 into its dust collection container; 3. Cleaning the cleaning components 2002 (e.g., mop, roller, etc.) of the cleaning robot 2000 within the cleaning base station 1000; 4. Adding clean water to the clean water tank of the cleaning robot 2000; 5. Recycling the dirt from the wastewater tank of the cleaning robot 2000 into its dirty container. The above maintenance types are merely illustrative descriptions and are not intended to limit this disclosure. The cleaning robot 2000 described herein includes, but is not limited to, sweeping robots, mopping robots, sweeping and mopping combos, and other cleaning equipment, which include, but are not limited to, having cleaning functions.

[0180] In summary, compared with existing technologies, the clean base station 1000 and the clean system 3000 have at least the following beneficial effects:

[0181] This disclosure uses the cleaning component 2002 to drive the cleaning rib plate 20, which in turn enables the second cleaning section 22 to clean the chassis 10. When the cleaning rib plate 20 is in a stopped state, the cleaning component 2002 rotates relative to the first cleaning section 21, causing the first cleaning section 21 to clean the cleaning component 2002. This process cleans both the chassis 10 and the cleaning component 2002 together, reducing dirt residue on the chassis 10. Furthermore, the cleaning rib plate 20 rotates at an angle greater than or equal to 360°, reducing blind spots and improving cleaning effectiveness. This further reduces dirt residue on the chassis 10, reduces the user's workload, and enhances the user experience.

[0182] Those skilled in the art should recognize that the above embodiments are merely illustrative of this disclosure and are not intended to limit this disclosure. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this disclosure fall within the scope of the disclosure.
