For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0040] Please see Figures 1 to 4 The base station water tank structure 100 of the present invention includes a base 12 and a scraper assembly 14.

[0041] The base 12 is provided with a water tank 16, which includes a cleaning tank 18. The side wall of the cleaning tank 18 is provided with a drain hole 20. The scraper assembly 14 is connected to the base 12. The scraper assembly 14 includes a first connector 22 and a scraper 24. The first connector 22 is connected to the scraper 24. The scraper 24 is located in the cleaning tank 18 and contacts the bottom surface of the cleaning tank 18. The first connector 22 is configured to connect to a second connector 27 on the mop disc 26 of the cleaning robot, so that the mop disc 26 drives the first connector 22 to rotate, thereby driving the scraper 24 to rotate.

[0042] In the aforementioned base station water tank structure 100, when the cleaning robot returns to the station to clean the mop 36, the first connector 22 can connect to the second connector 27 on the mop disc 26. When the mop disc 26 rotates, the first connector 22 and the second connector 27 can drive the scraper 24 to rotate, thereby scraping the bottom surface of the cleaning tank 18, preventing sewage residue in the cleaning tank 18, and solving the problem of odor in the base station water tank 16.

[0043] Specifically, the base station water tank structure 100 can be applied to a base station, allowing a cleaning robot to enter the base station. The base station can then perform operations such as dust collection, charging, and mop cleaning on the cleaning robot. For example, when the cleaning time or cleaning area of ​​the cleaning robot reaches a threshold, the cleaning robot needs to return to the base station, after which the base station can clean the mop 36.

[0044] More specifically, the base station water tank structure 100 also includes a mop scraper 28, which is mounted on the base 12. The mop scraper 28 includes a cleaning bracket 30 located in the cleaning tank 18, and the surface of the cleaning bracket 30 is provided with a plurality of protrusions 32. After the cleaning robot returns to the base station, the mop 36 of the mop assembly 34 contacts the protrusions 32 on the cleaning bracket 30. When the mop assembly 34 rotates, the debris on the mop 36 is scraped off along with the wastewater on the mop 36 by the protrusions 32 on the cleaning bracket 30 and falls into the cleaning tank 18.

[0045] The bottom of the cleaning tank 18 is inclined towards the drain hole 20. The sewage in the cleaning tank 18 flows towards the drain hole 20 under the action of gravity and flows out of the base station from the drain hole 20. However, relying solely on the inclination angle of the cleaning tank 18 to discharge sewage will result in sewage residue, causing the base station water tank 16 to smell.

[0046] In this invention, the first connector 22 can serve as a transmission end cap. The first connector 22 connects to the scraper 24, which contacts the bottom surface of the cleaning tank 18. When the cleaning robot returns to the base station, the second connector 27 on the mop disc 26 of the mop assembly 34 connects to the first connector 22, so that when the mop assembly 34 rotates, it can drive the scraper 24 to rotate, scraping and washing the bottom surface of the cleaning tank 18, preventing sewage residue in the cleaning tank 18, and solving the problem of odor in the base station water tank 16. The mop 36 can be installed on the mop disc 26, and the cleaning robot can drive the mop disc 26 to rotate, which in turn drives the mop 36 and the scraper 24 to rotate.

[0047] The present invention does not specifically limit the shape, material, and number of scraper strips 24. Optionally, the scraper strips 24 are made of elastic material, which can reduce the resistance when the scraper strips 24 rotate, making the cleaning of the mop 36 and the cleaning tank 18 more efficient.

[0048] exist Figure 2In the base 12, two cleaning tanks 18 are provided, each containing a cleaning bracket 30 and a scraper 24. Each cleaning bracket 30 has three cleaning arms 38. The end of one cleaning arm 38 of one cleaning bracket 30 is connected to the end of one cleaning arm 38 of the other cleaning bracket 30 to improve the stability of the mop scraper 28. Additionally, the connection point formed by the two ends of the two cleaning arms 38 can be used to install functional components. In one embodiment, the functional component can be a magnetically adsorbable component 84, enabling the cleaning bracket to be detachable. A protrusion 32 is provided on the top surface of the cleaning arm 38. Correspondingly, the cleaning robot has two mop assemblies 34 (e.g., left and right mop assemblies 34). After the cleaning robot returns to the base station, each mop assembly 34 contacts a corresponding cleaning bracket 30 and connects to a corresponding first connector 22, allowing the cleaning robot to clean each mop assembly 34 and each cleaning tank 18 separately. It is understood that the present invention does not specifically limit the number of cleaning tanks 18, cleaning brackets 30, and scrapers 24.

[0049] In some embodiments, the first connector 22 has a connecting portion 40 at the end away from the scraper 24. The connecting portion 40 is configured to engage with the groove 42 of the second connector 27 so that the first connector 22 rotates when the mop disc 26 rotates.

[0050] Thus, the protruding connecting part 40 can be matched with the groove 42 of the mop disc 26 to realize the transmission, and the transmission structure is simple and low cost.

[0051] Specifically, when the cleaning robot returns to the base station, the connecting part 40 can enter the groove 42. The connecting part 40 and the groove 42 can be connected by a non-circular structure, so that when the mop disc 26 rotates, it can drive the first connecting piece 22 to rotate, and then drive the scraper 24 to rotate, so as to scrape and wash the cleaning tank 18.

[0052] Optionally, the groove 42 of the mop disc 26 may be located in the middle of the mop disc.

[0053] In other embodiments, the first connector 22 may have a groove, and the second connector 27 may have a protruding connecting portion.

[0054] In some implementations, please refer to Figure 7 and Figure 10 The connecting part 40 includes a body 44 and a first locking arm 46. The first locking arm 46 is connected to the circumferential side of the body 44 and is configured to abut against a second locking arm 48 in the groove 42.

[0055] In this way, the rotation of the mop disc 26 can be transmitted to the scraper 24 by the two clamping arms abutting against each other.

[0056] Specifically, when the first clamping arm 46 and the second clamping arm 48 abut against each other, the rotation of the mop disc 26 can be transmitted to the body 44 through the abutting second clamping arm 48 and the first clamping arm 46, and the body 44 then drives the scraper 24 to rotate. The second clamping arm 48 has a groove 42 on its side wall.

[0057] After the cleaning robot returns to the base station, the connecting part 40 is located in the groove 42 of the mop tray 26. Please refer to... Figure 10 At this point, the first locking arm 46 and the second locking arm 48 may not yet have made contact. Figure 10 In this configuration, the mop disc 26 can rotate clockwise by a certain angle, and the second clamping arm 48 also rotates by a corresponding angle. The first clamping arm 46 is positioned within the rotational stroke of the second clamping arm 48. When the rotation of the second clamping arm 48 is blocked by the first clamping arm 46, the second clamping arm 48 abuts against the first clamping arm 46, preventing the second clamping arm 48 from rotating relative to the first clamping arm 46. The second clamping arm 48 will then drive the first clamping arm 46 to rotate together in a clockwise or counterclockwise direction, thereby driving the scraper 24 to rotate.

[0058] Optionally, the number of first clamping arms 46 and second clamping arms 48 may be two or more, which can make the rotation of the first connecting member 22 and the scraper 24 smoother. The number of first clamping arms 46 may be equal to or unequal to the number of second clamping arms 48. Please refer to... Figure 7 and Figure 10 The main body 44 is connected to two first locking arms 46, and the two connection points formed by the connection between the two first locking arms 46 and the main body 44 are arranged radially along the main body 44. The groove 42 is provided with two second locking arms 48, and the two connection points formed by the connection between the two second locking arms 48 and the side wall of the groove 42 are arranged radially along the groove 42.

[0059] In some embodiments, the first clamping arm 46 includes a first end 50 and a second end 52. The first end 50 is connected to the body 44, and the second end 52 is away from the body 44. The height of the first clamping arm 46 gradually increases along the direction from the second end 52 to the first end 50.

[0060] In this way, the first clamping arm 46 can guide the mop disc 26, making it easier for the connecting part 40 to enter the groove 42.

[0061] Specifically, along the direction from the second end 52 to the first end 50, the height of the first locking arm 46 gradually increases. That is, the height of the first locking arm 46 is smaller in the direction near the outer side of the first connector 22, and larger in the direction near the rotation axis of the first connector 22.

[0062] During the return process to the base station, the cleaning robot approaches the base station from far to near. When the mop disc 26 begins to contact the first clamping arm 46 on the outside of the first connector 22, the mop disc 26 can easily climb to the top of the first clamping arm 46 and move along the top of the first clamping arm 46 to reach the position of the body 44. This makes it easier and more accurate for the first connector 22 to enter the groove 42, and the connection efficiency between the mop disc 26 and the first connector 22 is also higher.

[0063] In some embodiments, the base station water tank structure 100 includes a mop scraper 28 mounted on a base 12, the mop scraper 28 including a cleaning bracket 30 located in a cleaning tank 18, and a first connector 22 rotatably passing through the cleaning bracket 30.

[0064] Thus, the scraper assembly 14 can be integrated into the mop scraper frame 28, simplifying the base station water tank structure 100.

[0065] Specifically, the cleaning bracket 30 is responsible for cleaning the mop 36. The first connector 22 is rotatably mounted on the cleaning bracket 30, and the scraper assembly 14 can be integrated into the mop scraper 28, eliminating the need for additional structural components to install the scraper assembly 14 and simplifying the base station water tank structure 100. In addition, when the mop assembly 34 rotates, the mop 36, the first connector 22, and the scraper 24 rotate, while the cleaning bracket 30 remains stationary. This allows for cleaning of the mop 36 while simultaneously scraping and washing the cleaning tank 18, improving cleaning efficiency.

[0066] In some embodiments, the cleaning bracket 30 has a through hole 54, and the scraper assembly 14 includes a sleeve 56 fixed in the through hole 54. A first connector 22 is rotatably inserted through the sleeve 56 and can drive the scraper 24 to move up and down along the axial direction of the sleeve 56. The scraper assembly 14 is configured such that when the mop disc 26 is connected to the first connector 22, the scraper 24 is in a first position, and when the mop disc 26 is separated from the first connector 22, the scraper 24 is in a second position. The first position is lower than the second position relative to the bottom surface of the cleaning tank 18.

[0067] Thus, the first connector 22 can drive the scraper 24 to rise and fall along the axial direction of the sleeve 56, so that when the mop disc 26 is connected to the first connector 22, the position of the scraper 24 is lower, and the scraping effect on the bottom surface of the cleaning tank 18 is better.

[0068] Specifically, when the cleaning robot returns to the base station, the mop tray 26 is in place and connected to the first connector 22. The scraper 24 can be located at a lower first position, and the contact area between the scraper 24 and the bottom surface of the cleaning tank 18 is increased, thereby improving the scraping effect of the cleaning tank 18.

[0069] After the cleaning robot leaves the base station, the mop disc 26 separates from the first connector 22, and the scraper 24 can be positioned in a higher second position. Optionally, the interference fit between the scraper 24 and the bottom surface of the cleaning tank 18 in the first position is greater than the interference fit between the scraper 24 and the bottom surface of the cleaning tank 18 in the second position. Therefore, in the second position, the scraper 24 does not need to work, the deformation of the scraper 24 is smaller, and the service life of the scraper 24 can be extended. In one example, the sleeve 56 can be a tubular object made of copper.

[0070] Optionally, the height difference between the first and second positions can be selected from the range [0.5mm, 1mm]. In one example, the height difference between the first and second positions can be 0.8mm.

[0071] In some implementations, please refer to Figure 8 and Figure 9 The scraper assembly 14 includes a reset member 58. The first connector 22 includes a shaft portion 60 and a head 62. The shaft portion 60 passes through a sleeve 56 and includes a third end 64 and a fourth end 66. The third end 64 is connected to the scraper 24, and the fourth end 66 is connected to the head 62. The reset member 58 abuts against the head 62 and the sleeve 56. The reset member 58 is configured to raise the scraper 24 from a first position to a second position.

[0072] Thus, when the mop disc 26 is separated from the first connector 22, the reset member 58 can raise the scraper 24 from the first position to the second position, and the scraper assembly 14 is reset.

[0073] Specifically, the head 62 may protrude radially from the shaft 60, with the shaft 60 and the connecting portion 40 located on opposite sides of the head 62. One end of the reset member 58 abuts against the lower surface of the head 62, and the other end of the reset member 58 abuts against the sleeve 56. Optionally, the inner wall of the sleeve 56 is provided with an annular receiving cavity 68, in which the reset member 58 may be at least partially located. The receiving cavity 68 can make the position of the reset member 58 more stable during compression and extension, preventing displacement of the reset member 58 and thus ensuring the rotation of the scraper 24 is stable. Optionally, the third end 64 may be fastened to the scraper 24 with screws.

[0074] Please combine Figure 4 and Figure 5 Initially, before the cleaning robot enters the base station, the scraper 24 does not need to work, and the reset member 58 is at the installation height. Under the action of the reset member 58, the scraper 24 is in a higher second position, and the deformation of the scraper 24 is small. Because the bottom of the cleaning tank 18 is inclined towards the drain hole 20, Figure 4 The scraper 24 shown is located at a lower position on the bottom surface of the cleaning tank 18. The interference fit of the scraper 24 is small, and the deformation is small.

[0075] During the movement of the cleaning robot, the mop disc 26 can press down on the first connecting piece 22 and the scraper 24, while the sleeve 56 remains stationary. The scraper 24 descends from the second position to the first position (target position), such as... Figure 6 As shown, the deformation of the scraper 24 increases, and the contact area between the scraper 24 and the bottom surface of the cleaning tank 18 increases. The first connector 22 compresses the reset member 58 under the pressure of the mop disc 26 via the head 62. The reset member 58 shortens in length when compressed. When the cleaning robot's mop disc 26 is in position, the first connector 22 connects to the mop disc 26. The reset member 58 is at its working height, the scraper 24 is interference-fitted with the bottom surface of the cleaning tank 18, and when the mop disc 26 rotates, the first connector 22 drives the scraper 24 to scrape and clean the bottom surface of the cleaning tank 18. Figure 6 The interference fit between the middle scraper 24 and the bottom surface of the cleaning tank 18 is greater than... Figure 5 The interference fit between the scraper 24 and the bottom surface of the cleaning tank 18, therefore, in Figure 6 The deformation of scraper 24 is relatively large.

[0076] After the cleaning robot leaves the base station, the mop disc 26 separates from the first connector 22, the pressure applied by the mop disc 26 to the first connector 22 disappears, the reset member 58 extends, and drives the first connector 22 upward, so that the first connector 22 drives the scraper 24 to rise from the first position to the second position, and the scraper assembly 14 resets.

[0077] The reset element 58 may include, but is not limited to, elastic elements such as tension springs, torsion springs, and spring sheets, as well as other reset elements 58 that can be deformed by external force and can recover their deformation when the external force is removed. Figure 8 and Figure 9 The reset element 58 shown is a tension spring, which is sleeved on the shaft 60.

[0078] In some embodiments, the base 12 is provided with a first positioning part 70, the mop scraper 28 includes a positioning member 72 connected to the cleaning bracket 30, the positioning member 72 is provided with a second positioning part 74, and the first positioning part 70 is connected to the second positioning part 74.

[0079] In this way, the mop scraper 28 can be positioned on the base 12 through the two positioning parts, which facilitates the installation of the mop scraper 28.

[0080] Specifically, in one embodiment, the mop scraper 28 is detachably mounted on the base 12. When installing the mop scraper 28, the first positioning part 70 and the second positioning part 74 position the mop scraper 28, allowing for quick installation.

[0081] exist Figure 2In the illustrated embodiment, the side wall of the cleaning tank 18 is provided with a mounting groove 76. The first positioning part 70 includes a positioning hole 78 provided on the bottom surface of the mounting groove 76, and the second positioning part 74 includes a positioning pin 80 provided on the positioning member 72.

[0092] In this way, the water-blocking strip 86 can block the sewage when cleaning the mop 36, preventing or reducing the sewage from spilling out of the cleaning tank 18.

[0093] Specifically, in Figure 2 In this design, the edge of the cleaning tank 18 furthest from its bottom surface can be its top edge. A water-blocking strip 86 is located at the top edge of the cleaning tank 18, extending a certain height above it. When the mop assembly 34 rotates, the mop 36 may throw wastewater outside the cleaning tank 18. By providing a water-blocking strip 86 at the top edge of the cleaning tank 18, the wastewater thrown from the mop 36 can be blocked by the water-blocking strip 86 and slide back into the cleaning tank 18, thereby preventing or reducing wastewater spillage outside the cleaning tank 18.

[0094] Optionally, the water-blocking strip 86 is arranged along the top edge of the cleaning tank 18, which can improve the water-blocking rate of the water-blocking strip 86 against sewage. Optionally, the water-blocking strip 86 is fixed to the base 12 by adhesive bonding.

[0095] In summary, the present invention distributes the task of rotating the scraper 24 to the mop disc 26 (such as two mop discs 26 on the left and right), and achieves self-cleaning of the base station cleaning tank 18 by rotating the scraper 24 through the connection between the mop disc 26 and the first connecting member 22. It is also easy to disassemble and assemble, which is conducive to quick replacement or deep cleaning.
