[0059] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0061] The present application provides a cleaning disc assembly, comprising a cleaning disc, a cleaning structure and a driving structure. A drain trough is provided on the cleaning disc, and the driving structure is used to drive the cleaning structure to push dirt on the bottom surface of the cleaning disc into the drain trough.

[0062] The above-mentioned cleaning structure includes at least one telescopic arm, on which a cleaning member is provided that abuts against the bottom surface of the cleaning disk. The driving structure is connected to one end of the telescopic arm to drive the telescopic arm to rotate back and forth around the end, and the other end of the telescopic arm abuts against the side wall of the cleaning disk.

[0063] It can be understood that the cleaning structure includes at least one telescopic arm, and the telescopic arm is provided with a cleaning member that abuts against the bottom surface of the cleaning disc, and one end of the telescopic arm can reciprocate around the end under the drive of the driving structure, and the other end of the telescopic arm abuts against the side wall of the cleaning disc, so that the dirt on the bottom surface of the cleaning disc can be pushed into the drain trough through the cleaning member during the rotation, and the telescopic arm can always contact the side wall of the cleaning disc by extending or shortening itself, so that when there is a corner in the cleaning disc, the dirt at the corner can be cleaned, avoiding dirt remaining at the corner of the cleaning disc for a long time, thereby improving user experience.

[0064] In some embodiments, the telescopic arm can be rotated 360 degrees. In this case, the telescopic arm can rotate 360 degrees around the end connected to the drive structure, and the end of the telescopic arm connected to the drive structure is located at the center of the cleaning disc. In this case, a drain chute is provided in the direction of rotation of the telescopic arm, and one or more drain chute can be provided. If multiple drain chute are provided, the drain chute is spaced apart along the direction of rotation of the telescopic arm.

[0065] Furthermore, the number of the telescopic arms can be set to one or more. When there are multiple telescopic arms, all of the telescopic arms are connected to the driving structure. At this time, the driving structure can drive the multiple telescopic arms to rotate simultaneously.

[0066] It should be noted that the shape of the above-mentioned cleaning disc can be circular, track-circular, square-circular, polygonal, etc. In addition, the cleaning disc may include at least one disc body, each disc body is provided with at least one telescopic arm, and at this time, one end of the telescopic arm connected to the drive structure is located at the center of the disc body.

[0067] In some embodiments, the rotation angle of the telescopic arm can also be selected to be less than 360°. In this case, the shape of the cleaning disc can be semicircular, semi-elliptical, semi-square, etc.

[0068] The sidewall of the cleaning disc is provided with a first disc side surface in the direction of rotation of the telescopic arm, and the telescopic arm can seal against the first disc side surface. In other words, when the telescopic arm stops moving, it can seal against the first disc side surface. Thus, when cleaning the mopping and wiping parts of the cleaning robot, the telescopic arm can be pressed against the first disc side surface, preventing dirt from entering the gap between the telescopic arm and the first disc side surface, and preventing dirt from remaining in this area for a long time.

[0069] It should be noted that the cleaning disc is provided with a drainage trough corresponding to each telescopic arm, or a drainage trough corresponding to two telescopic arms, in which case the two telescopic arms share a drainage trough. For example, when the cleaning structure includes a telescopic arm, the drainage trough is provided on one side of the telescopic arm in the direction of rotation, while the cleaning disc has a first disc side surface for the telescopic arm to abut against on the other side of the telescopic arm in the direction of rotation. In this way, when the telescopic arm is not in operation, it abuts against the first disc side surface of the cleaning disc. When the cleaning disc needs to be cleaned, the telescopic arm rotates under the drive mechanism to push dirt on the bottom surface of the cleaning disc into the drainage trough.

[0070] When multiple telescopic arms are provided in the cleaning disc, the cleaning disc can be divided into multiple cleaning areas, and each cleaning area can be provided with a corresponding telescopic arm. At this time, each cleaning area can be provided with a corresponding sewage trough, or two of the multiple cleaning areas can be grouped together, and the two cleaning areas in each group share a sewage trough, or some of the multiple cleaning areas can be grouped together, and the two cleaning areas in each group share a sewage trough, and the remaining cleaning areas are provided with a separate sewage trough.

[0071] At this time, the sewage trough is arranged on one side of the telescopic arm in the rotation direction, and the cleaning disc can have a first disc side surface for the telescopic arm to abut against on the other side of the telescopic arm in the rotation direction.

[0072] For example, a cleaning pan is provided with two telescopic arms, the two telescopic arms share a drainage trough, and the cleaning pan is provided with a first pan side surface corresponding to the two telescopic arms. In this case, the cleaning pan can be understood as being divided into two cleaning areas, the two cleaning areas share a drainage trough, and a telescopic arm is provided for each cleaning area, which rotates to clean the dirt in the corresponding cleaning area.

[0073] In addition, the two first disk side surfaces may be arranged to be coplanar. Of course, the two first disk side surfaces may also be arranged to form a preset angle, which is less than 180° or greater than 180° and less than 360°.

[0074] For example, referring to Figure 1 and Figure 2 The sidewall of the cleaning tray 1 has a first tray side surface 102 extending in a first direction. A drainage trough 121 is provided on the cleaning tray 1 along a second direction, the first direction being perpendicular to the second direction. Two telescopic arms 21 are provided. In the first direction, the drainage trough 121 is located between the two telescopic arms 21. The telescopic arms 21 can seal against the first tray side surface 102 along their length.

[0075] It can be understood that the washing pan 1 is now divided into two cleaning areas, each of which is provided with a telescopic arm 21, and the two cleaning areas share a drain trough 121. The telescopic arm 21 abuts against the first pan side 102. When the bottom surface 101 of the washing pan 1 needs to be cleaned, the telescopic arm 21 begins to rotate under the drive mechanism 3 and gradually approaches the drain trough 121. During this process, the cleaning member 22 on the telescopic arm 21 scrapes the dirt from the bottom surface 101 of the washing pan 1, and finally scrapes the dirt into the drain trough 121.

[0076] Furthermore, the side wall of the above-mentioned cleaning disc 1 has two arc-shaped second disc sides 103. In the first direction, the two second disc sides 103 are respectively located on both sides of the drain trough 121, and the two second disc sides 103 are both connected to the first disc side 102, and the other ends of the two telescopic arms 21 are respectively abutted against the two second disc sides 103.

[0077] It is understood that the telescopic arm 21 can abut against the first disc side 102, and the other end of the telescopic arm 21 abuts against the second disc side 103. In this way, when the telescopic arm 21 rotates under the drive of the driving structure 3, the telescopic arm 21 always abuts against the second disc side 103. The second disc side 103 is configured to be curved, which facilitates the smooth movement of the telescopic arm 21.

[0078] Reference Figure 3 The telescopic arm 21 is provided with a first sealing member 23 extending along the extension direction of the telescopic arm 21 . The first sealing member 23 can abut against the first disc side 102 to block the gap between the telescopic arm 21 and the first disc side 102 .

[0079] It is understood that the seal between the telescopic arm 21 and the first tray side 102 is achieved by the first sealing member 23. The first sealing member 23 is preferably a rubber strip that can produce elastic deformation. In this way, when the telescopic arm 21 abuts against the first tray side 102, the rubber strip is deformed and pressed against the first tray side 102, thereby ensuring a sealing effect.

[0080] For example, referring to Figures 3 to 5 The telescopic arm 21 includes a first arm 211, a second arm 212 and an elastic member 213. One end of the first arm 211 is connected to the driving structure 3, and the other end is provided with a receiving cavity for inserting the second arm 212. The elastic member 213 is arranged in the receiving cavity and is limited to the end of the second arm 212 extending into the receiving cavity. In this way, under the action of the elastic member 213, the distance that the second arm 212 extends out of the receiving cavity increases or decreases, thereby adapting to the shape of the cleaning disk 1, always contacting the side wall of the cleaning disk 1 and leaving no dead angle when rotating.

[0081] Both the first arm 211 and the second arm 212 are provided with a cleaning member 22. The cleaning member 22 of the second arm 212 always partially overlaps with the cleaning member 22 of the first arm 211 along the length of the telescopic arm 21. This prevents the presence of uncleaned areas on the cleaning tray 1 as the second arm 212 is extended further, thereby affecting the cleaning effect. Furthermore, both the first arm 211 and the second arm 212 are provided with the first sealing member 23. The first sealing member 23 of the second arm 212 always partially overlaps with the first sealing member 23 of the first arm 211 along the length of the telescopic arm 21, ensuring a good seal.

[0082] It should be noted that a first notch is provided on the first arm 211 corresponding to the cleaning member 22 on the second arm 212, communicating with the accommodating cavity. The first notch extends along the extension direction of the telescopic arm 21, allowing the cleaning member 22 on the second arm 212 to leak out of the first notch and contact the bottom surface 101 of the cleaning tray 1. A second notch is provided on the first arm 211 corresponding to the first sealing member 23 on the second arm 212, communicating with the accommodating cavity. The second notch extends along the extension direction of the telescopic arm 21, allowing the first sealing member 23 on the second arm 212 to leak out of the second notch and abut against the first tray side surface 102.

[0083] Furthermore, a second sealing member 24 is provided at one end of the telescopic arm 21 away from the driving structure 3 , and the second sealing member 24 abuts against the side wall of the cleaning tray 1 .

[0084] It can be understood that the second arm 212 is provided with the above-mentioned second seal 24 at the end away from the elastic member 213. The second seal 24 can seal the gap between the telescopic arm 21 and the side wall of the cleaning disk 1 to prevent dirt from entering the gap between the end of the telescopic arm 21 away from the driving structure 3 and the side wall of the cleaning disk 1.

[0085] The second sealing member 24 is preferably an elastically deformable rubber strip, so that when the telescopic arm 21 abuts against the side wall of the cleaning tray 1 , the rubber strip is deformed and pressed against the side wall of the cleaning tray 1 , thereby ensuring a sealing effect.

[0086] The second seal 24 can be integrally provided with the first seal 23 on the second arm 212. Alternatively, they can be provided separately, that is, the first seal and the second seal are provided separately, and the two seals cooperate to cover the gap between the second arm and the side wall of the washing tray.

[0087] In some embodiments, reference Figure 6 A second sealing member 24 is provided at one end of the telescopic arm 21 away from the driving structure 3 , and the second sealing member 24 abuts against the side wall of the cleaning tray 1 .

[0088] It can be understood that a second seal 24 is provided at the end of the telescopic arm 21 away from the driving structure 3. The second seal 24 can seal the gap between the telescopic arm 21 and the side wall of the cleaning disk 1, thereby preventing dirt from remaining in the gap between the end of the telescopic arm 21 away from the driving structure 3 and the side wall of the cleaning disk 1.

[0089] In some embodiments, reference Figures 7 to 9 The cleaning tray 1 includes a cleaning tray body 11 and a sewage discharge member 12. The cleaning tray body 11 is recessed to form a groove. The sewage discharge member 12 is provided with a sewage discharge groove 121. The sewage discharge member 12 is arranged in the groove and the top surface of the sewage discharge member 12 is sealed with the bottom surface 101 of the cleaning tray body 11.

[0090] The driving structure 3 includes a driving member and a transmission structure. The transmission structure is arranged in the groove. One end of the telescopic arm 21 is located above the sewage discharge member 12 and is connected to the transmission structure.

[0091] Understandably, at this time, the cleaning disc 1 is of split design, consisting of a cleaning disc body 11 and a sewage discharge part 12. The setting of the groove on the cleaning disc body 11 provides an installation space for the sewage discharge part 12, and also provides an installation space for the transmission structure, which is conducive to the hidden design of the transmission structure. Moreover, the cleaning disc body 11, the sewage discharge part 12 and the transmission structure form a whole after assembly, which can realize modular assembly and facilitate installation and disassembly.

[0092] It should be noted that the above-mentioned driving member can be installed on the cleaning disc 1 or on the cleaning base station. When the cleaning disc 1 is detachably mounted on the cleaning base station, the driving member and the transmission structure can be configured to be detachably connected, so that the entire cleaning disc assembly can be removed from the cleaning base station for cleaning.

[0093] Specifically, refer to Figure 8 and Figure 9 The transmission structure includes a meshing worm 31 and a worm wheel 32. The worm 31 is connected to a driving member, and the worm wheel 32 is connected to the telescopic arm 21. In this way, the driving member drives the worm 31 to rotate, the worm 31 drives the worm wheel 32 to rotate, and the worm wheel 32 drives the telescopic arm 21 to rotate, thereby cleaning the cleaning dish 1 through the telescopic arm 21. Among them, the driving member is preferably a motor.

[0094] The worm wheel 32 and the worm 31 are both arranged in the groove, the worm 31 is passed through the sewage discharge part 12, and the sewage discharge part 12 is provided with a space for accommodating the worm wheel 32. This not only realizes the hidden design of the worm wheel and the worm, but also provides protection for the worm and the worm wheel through the sewage discharge part 12 and the cleaning disc body 11.

[0095] It should be noted that the telescopic arm 21 is provided with a plug-in post, and the worm gear 32 is provided with a socket. The plug-in post is inserted into the socket to connect the telescopic arm 21 and the worm gear 32. The sewage discharge member 12 is provided with a through-hole for the plug-in post on the telescopic arm 21 to pass through. In addition, to prevent relative rotation between the telescopic arm 21 and the worm gear 32, both the socket and the socket are provided with at least one anti-rotation limit surface. When the plug-in post is inserted into the socket, the anti-rotation limit surfaces of the plug-in post and the socket align one-to-one.

[0096] For example, referring to Figure 8 and Figure 9 The sidewall of the cleaning tray 1 has a first tray side surface 102 extending in a first direction, and a drain chute 121 extending in a second direction, the first direction being perpendicular to the second direction. Two telescopic arms 21 are provided. In the first direction, the drain chute 121 is located between the two telescopic arms 21, and the telescopic arms 21 can be sealed against the first tray side surface 102 along their length. The sidewall of the cleaning tray 1 has two arcuate second tray side surfaces 103. In the first direction, the two second tray side surfaces 103 are located on either side of the drain chute 121, and both second tray side surfaces 103 are connected to the first tray side surface 102. The other ends of the two telescopic arms 21 abut against the two second tray side surfaces 103, respectively.

[0097] It is understood that two worm wheels 32 and two worm gears 31 are provided, and the two worm gears 31 are spaced apart in the first direction, and one worm wheel 32 and one worm gear 31 are associated with one telescopic arm 21. In this case, one driving member can drive both worm gears 31 simultaneously, or two driving members can be provided, and each of the two driving members can drive the two worm gears respectively.

[0098] When one driving member drives two worms 31 at the same time, the driving member can simultaneously drive the two gears to rotate through gear transmission. The two worms 31 are respectively connected to the two gears and can rotate synchronously with the gears.

[0099] In some embodiments, the cleaning disc itself is recessed to form the aforementioned drain trough, and the drive structure is disposed on the back of the cleaning disc, that is, the drive structure is located outside the cleaning chamber of the cleaning disc. The drive structure may be a motor, which directly drives the telescopic arm to rotate. Alternatively, the drive structure may be a motor and a transmission structure, wherein the motor simultaneously drives multiple telescopic arms to rotate through the transmission structure, and the transmission structure is a gear set, wherein the motor shaft drives multiple gears to rotate through gear transmission, and the multiple gears are respectively connected to the multiple telescopic arms, thereby achieving synchronous rotation of the multiple telescopic arms. This is suitable for a situation where the cleaning disc is divided into multiple cleaning areas, each cleaning area is provided with a corresponding telescopic arm, and each telescopic arm rotates to clean the corresponding cleaning area.

[0100] In some embodiments, reference Figures 10 to 12 The drain trough 121 is provided with a drain outlet 122 at one end thereof in its extending direction.

[0101] The cleaning disc assembly 10 further includes a dirt pushing structure 4 , which includes a dirt driving assembly and a dirt pushing plate 42 . The dirt pushing plate 42 is disposed in the dirt trough 121 , and the dirt driving assembly can drive the dirt pushing plate 42 to reciprocate in the extension direction of the dirt trough 121 .

[0102] It is understood that when the telescopic arm 21 rotates under the drive of the drive structure 3 to clean the bottom surface 101 of the washing tray 1 through the cleaning member 22, the dirt pushing plate 42 is located at the end of the drainage trough 121 in its extending direction away from the drainage outlet 122. After the telescopic arm 21 pushes the dirt into the drainage trough 121 through the cleaning member 22, the dirt pushing plate 42 moves in the drainage trough 121 toward the drainage outlet 122 under the action of the drainage drive assembly. In this way, the dirt in the drainage trough 121 is concentrated at the drainage outlet 122 under the action of the dirt pushing plate 42, which facilitates the dirt to be extracted by the sewage extraction structure.

[0103] In a specific implementation, referring to Figure 12 The above-mentioned sewage drive assembly includes a telescopic push rod 41 and a reset elastic member (not shown in the figure). The reset elastic member is limited between the sewage pushing plate 42 and the cleaning tray 1. The telescopic push rod 41 is installed in the cleaning tray 1. The telescopic push rod 41 can be extended to push the sewage pushing plate 42 in the sewage trough 121 toward the sewage outlet 122. During this process, the reset elastic member is stretched. When the telescopic push rod 41 is retracted, the sewage pushing plate 42 is moved in the sewage trough 121 away from the sewage outlet 122 under the action of the reset elastic member as the telescopic push rod 41 continues to retract.

[0104] The aforementioned resetting elastic member may be provided with one, and the telescopic push rod 41 may penetrate the resetting elastic member when the telescopic push rod 41 is extended. Alternatively, multiple resetting elastic members may be provided, and the multiple resetting elastic members are spaced apart in the width direction of the drainage trough 121, and the telescopic push rod 41 can push the sewage pushing plate 42 at a position intermediate the sewage pushing plate 42 in the width direction of the sewage trough 121.

[0105] It should be noted that the telescopic push rod 41 can be an electric push rod, a cylinder, etc.

[0106] For example, referring to Figures 10 to 12 The sidewall of the cleaning tray 1 has a first tray side surface 102 extending in a first direction, and a drain chute 121 extending in a second direction, the first direction being perpendicular to the second direction. Two telescopic arms 21 are provided. In the first direction, the drain chute 121 is located between the two telescopic arms 21, and the telescopic arms 21 can be sealed against the first tray side surface 102 along their length. The sidewall of the cleaning tray 1 has two arcuate second tray side surfaces 103. In the first direction, the two second tray side surfaces 103 are located on either side of the drain chute 121, and both second tray side surfaces 103 are connected to the first tray side surface 102. The other ends of the two telescopic arms 21 abut against the two second tray side surfaces 103, respectively.

[0107] The telescopic arm 21 is driven by the driving structure 3 to rotate from the state of being against the first disc side 102 to the direction close to the drainage groove 121, and the cleaning member 22 cleans the bottom surface 101 of the cleaning disc 1 to push the dirt on the bottom surface 101 of the cleaning disc 1 into the drainage groove 121. Figure 10 As shown. The telescopic arm 21 is finally rotated 90 degrees under the drive of the driving structure 3, pushing the dirt into the sewage trough 121. At this time, the position of the telescopic arm 21 is as shown. Figure 11 After the telescopic arm 21 pushes the dirt into the drain trough 121, the telescopic top rod 41 extends to drive the dirt pushing plate 42 to move in the drain trough 121 and push the dirt to the drain outlet 122. Figure 12 Then the telescopic push rod 41 gradually contracts and the dirt pushing plate 42 moves in the direction away from the drain outlet 122 in the drain trough 121 under the action of the reset elastic member, and finally stops at one end of the drain trough 121 away from the drain outlet 122.

[0108] Alternatively, in some other embodiments, a drain outlet connected to the drain trough may not be provided, that is, the dirt in the drain trough is not discharged through the drain outlet. In this case, a drain pipe extending into the drain trough may be provided, the drain pipe being located at one end in the direction in which the drain trough extends, and a water spraying structure being provided at the other end in the direction in which the drain trough extends. The water spraying structure can spray water into the drain trough so that the dirt is carried by the water and flows to the drain pipe for being drawn out by the drain pipe.

[0109] At this point, the sewage pipe can be connected to the sewage tank on the cleaning base station. The extraction device on the cleaning base station vacuums the sewage tank, allowing dirt to enter the sewage tank through the sewage pipe. The sewage pipe, sewage tank, and extraction device can also extract sewage from the cleaning tray when cleaning the mopping parts of the cleaning robot, as well as sewage discharged into the sewage box of the cleaning robot.

[0110] In some embodiments, reference Figure 13 and Figure 14 The drain trough 121 is provided with a drain outlet 122 at one end thereof in its extending direction. A reversible door 13 may be provided at the drain outlet 122. The reversible door 13 closes the drain outlet 122 in a natural state, but the reversible door 13 may be turned toward the drain trough 121 by a force to open the drain outlet.

[0111] It is understandable that by providing the flip door 13, when there is sewage in the drain tank 121, the flip door 13 closes the drain outlet 122. When there is no sewage in the drain tank 121, the flip door 13 is opened to allow the dirt in the drain tank 121 to be discharged through the drain outlet 122.

[0112] For example, the flip door 13 can flip outward from the drain trough 121 to open the drain outlet when the extraction structure is evacuating air. The extraction structure can be an air pump or a vacuum pump to vacuum the sewage box connected to the drain outlet 122 and draw the dirt into the sewage box. The sewage box and the extraction structure can be installed on the cleaning tray or on other components of the cleaning base station, such as the base station base.

[0113] It should be noted that the above-mentioned flip door 13 can be installed on the cleaning tray 1 through a torsion spring. Under the action of the torsion spring, the flip door 13 closes the sewage outlet 122 in a natural state. When the flip door 13 is subjected to force to overcome the action of the torsion spring, it can flip open the sewage outlet 122.

[0114] Furthermore, the cleaning disc assembly 10 also includes a dirt pushing structure 4, which includes a dirt discharge drive assembly and a dirt pushing plate 42. The dirt pushing plate 42 is arranged in the dirt discharge groove 121, and the dirt discharge drive assembly can drive the dirt pushing plate 42 to move back and forth in the extension direction of the dirt discharge groove 121.

[0115] It is understood that when the telescopic arm 21 rotates under the drive of the drive structure 3 to clean the bottom surface 101 of the washing tray 1 through the cleaning member 22, the dirt pushing plate 42 is located at the end of the drainage trough 121 in its extending direction away from the drainage outlet 122. After the telescopic arm 21 pushes the dirt into the drainage trough 121 through the cleaning member 22, the dirt pushing plate 42 moves in the drainage trough 121 toward the drainage outlet 122 under the action of the drainage drive assembly. In this way, the dirt in the drainage trough 121 is concentrated at the drainage outlet 122 under the action of the dirt pushing plate 42, which facilitates the dirt to be extracted by the extraction structure.

[0116] In a specific implementation, referring to Figure 13 The above-mentioned sewage drive assembly includes a telescopic push rod and a reset elastic member (not shown in the figure). The reset elastic member is limited between the sewage pushing plate 42 and the cleaning tray 1. The telescopic push rod is installed in the cleaning tray 1. The telescopic push rod can be extended to push the sewage pushing plate 42 in the sewage trough 121 toward the sewage outlet 122. During this process, the reset elastic member is stretched. When the telescopic push rod is retracted, the sewage pushing plate 42 is moved in the sewage trough 121 away from the sewage outlet 122 under the action of the reset elastic member as the telescopic push rod continues to retract.

[0117] The aforementioned resetting elastic member may be provided with one, and the telescopic push rod may penetrate the resetting elastic member when the telescopic push rod is extended. Alternatively, the resetting elastic member may be provided with multiple, and the multiple resetting elastic members are spaced apart in the width direction of the drainage trough 121, and the telescopic push rod may push the sewage pushing plate 42 at a position intermediate the sewage pushing plate 42 in the width direction of the sewage trough 121.

[0118] It should be noted that the telescopic push rod can be an electric push rod, a cylinder, etc.

[0119] Alternatively, in other embodiments, the sewage outlet may not be provided with a reversible door. For example, a water spraying structure may be used to spray water into the sewage tank, so that the dirt is discharged from the sewage outlet 122 under the influence of the water flow. In this case, there is no need to provide a dirt pushing structure.

[0120] In some embodiments, the telescopic arm is provided with a cleaning assembly capable of cleaning the mopping and wiping elements of the cleaning robot. The cleaning assembly includes at least one of a scraping bar, toothed scraping teeth, and a brush, and is configured to clean the mopping and wiping elements of the cleaning robot through rotation of the telescopic arm. Of course, the cleaning assembly may also be configured with other structures capable of cleaning the mopping and wiping elements, which are not listed here.

[0121] The present application also provides a cleaning base station 100 , which includes the cleaning disc assembly 10 in any of the above embodiments.

[0122] Reference Figure 15 and Figure 16 The cleaning base station 100 includes a base station base 20, on which the cleaning disc assembly 10 is mounted. The cleaning base station 100 also includes a lower body 30, which is connected to the base station base 20 and forms a base station cavity with the base station base 20 for the cleaning robot to enter. The cleaning disc assembly 10 is located within the base station cavity. After entering the base station cavity, the cleaning robot can replenish water, clean the mopping parts on the cleaning robot, and drain the wastewater in the wastewater box on the cleaning robot into the cleaning disc 1.

[0123] Furthermore, the cleaning base station 100 is provided with a water injection pipe 5, which can be connected to the water injection port on the cleaning robot after the cleaning robot enters the base station cavity, so as to inject water into the clean water box of the cleaning robot through the water injection port.

[0124] In some embodiments, reference Figures 17 to 19 The drainage trough 121 is provided with a drainage outlet 122 at one end thereof. The cleaning base station 100 further includes a drainage structure having an exhaust branch connected to the drainage outlet to extract dirt in the drainage trough 121 through the drainage outlet 122, thereby automatically cleaning the dirt in the drainage trough 121 and improving the user experience.

[0125] Furthermore, the cleaning base station 100 is provided with a dust collecting duct (such as Figure 17 The dirt in the drainage trough 121 can be drawn into the dust box or dust bag on the cleaning base station 100 through the drainage port 122 and the dust collecting duct through the drainage structure.

[0126] For example, the above-mentioned sewage discharge structure can be selected from but not limited to an air pump, a centrifugal fan, a vacuum pump, an ion pump, etc. to achieve vacuuming of the dust box or dust bag. The sewage discharge structure is arranged on the base 20 or the lower body 30 of the base station.

[0127] Furthermore, the cleaning tray 1 is provided with a reversible door 13 at the drain outlet 122. The reversible door 13 closes the drain outlet 122 in a natural state, but can be reversed to the outside of the drain tank 121 to open the drain outlet when the drain structure is evacuated.

[0128] It is understood that by providing the flip door 13, when there is sewage in the drain trough 121, the flip door 13 can close the drain outlet 122, preventing the sewage in the drain trough 121 from entering the dust collection air duct through the drain outlet 122. When there is no sewage in the drain trough 121, the flip door 13 can be opened by the sewage discharge structure to allow the residual dirt in the drain trough 121 to be extracted.

[0129] As can be understood, the cleaning base station 100 is provided with a sewage tank (not shown) and an extraction device (not shown). The extraction device has an exhaust pipe connected to the sewage tank to evacuate the sewage tank so that the sewage on the cleaning plate 1 enters the sewage tank. The sewage tank is connected to a sewage pipe 6, which extends into the cleaning plate 1.

[0130] For example, the extraction device may be selected from but not limited to an air pump, a centrifugal fan, a vacuum pump, an ion pump, etc. to achieve vacuuming of the sewage tank.

[0131] It should be noted that the cleaning base station may also be provided with a drying structure for blowing hot air into the sewage tank to dry the dirt in the sewage tank. The drying structure can dry the dirt in the sewage tank, thereby preventing the dirt from carrying moisture when the sewage structure draws the dirt out through the sewage outlet.

[0132] The drying mechanism can be a fan, heater, and hot air duct. The fan blows air toward the heater, and the heated air is transported to the drain tank via a hot air duct. The hot air duct can be a passageway within the base station base, connected to the drain tank through a hole in the cleaning tray; or it can be a pipeline installed outside the base station base.

[0133] In some embodiments, the cleaning base station further includes a sewage discharge structure, which includes a water spraying member disposed in a sewage trough to spray water into the sewage trough so that dirt in the sewage trough is discharged through a sewage outlet.

[0134] Understandably, in this case, there is no need to set up a dirt-pushing structure, and the sewage generated when cleaning the wiping parts on the cleaning robot and the sewage discharged into the cleaning tray by the sewage box of the cleaning robot are all discharged through the sewage outlet.

[0135] It is understood that the cleaning base station is provided with a sewage tank and an extraction device, the extraction device having an exhaust pipe connected to the sewage tank to vacuum the sewage tank so that the sewage on the cleaning plate enters the sewage tank. The sewage tank is connected to a sewage pipe, which is connected to the above-mentioned sewage outlet.

[0136] For example, the extraction device may be selected from but not limited to an air pump, a centrifugal fan, a vacuum pump, an ion pump, etc. to achieve vacuuming of the sewage tank.

[0137] In some embodiments, reference Figure 20 The cleaning tray 1 is not provided with a sewage outlet. In this case, the cleaning base station 100 is provided with a sewage pipe 6 extending into the cleaning tray 1. The sewage pipe 6 is located at one end of the sewage trough 121 in the direction of extension. The cleaning base station 100 also includes a sewage discharge structure, which includes a water spraying member 7 disposed in the sewage trough 121. The water spraying member 7 is located at the other end of the sewage trough 121 in the direction of extension. The water spraying member 7 sprays water into the sewage trough 121 so that the dirt in the sewage trough 121 is drawn out through the sewage pipe 6, thereby automatically cleaning the dirt in the sewage trough 121 and improving the user experience.

[0138] In other words, the dirt in the drain trough 121 is driven by the water sprayed by the water spraying member 7 to flow to the vicinity of the drain pipe 6 and is drawn out by the drain pipe 6. Moreover, the flushing ability of the water sprayed by the water spraying member 7 can be increased by pressurizing, so that the dirt in the drain trough 121 flows quickly to the vicinity of the drain pipe 6 and accumulates.

[0139] It is understood that the cleaning base station 100 is provided with a sewage tank (not shown in the figure) and an extraction device (not shown in the figure). The extraction device has an exhaust pipe that is connected to the sewage tank to vacuum the sewage tank so that the sewage on the cleaning tray 1 enters the sewage tank. The sewage tank is connected to a sewage pipe 6.

[0140] In some embodiments, the cleaning disc is detachably mounted on the base station. The cleaning base station further comprises a driving assembly disposed on the base station base, the driving assembly being detachably connected to the driving structure.

[0141] Understandably, the drive structure is driven by the drive assembly, meaning that in this case, the drive structure acts as a transmission. The cleaning tray can be removed from the base station, and the drive structure can be disconnected from the drive assembly, allowing the entire cleaning tray assembly to be removed from the base station, making it easier to clean the cleaning tray.

[0142] The driving component can be a motor provided on the base of the base station, and the motor drives the telescopic arm to rotate through the driving structure.
