Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning tank structure and cleaning equipment. Background Technology

[0002] Current robotic vacuum cleaners often leave gaps between themselves and blind spots when cleaning along walls, corners, and the edges of obstacles. Related technologies typically employ a main mop and side mops, with the side mops located near the outer edge of the main mop and extending into these blind spots for cleaning. After completing their cleaning tasks, both the main and side mops become dirty and need to be returned to the base station for washing. Therefore, it is necessary to provide a washing tank structure that can effectively clean both the main and side mops. Utility Model Content

[0060] Please see Figures 1 to 4A cleaning tank structure 100 according to an embodiment of the present invention includes a first cleaning tank 10, a second cleaning tank 12, a first scraper 14, and a second scraper 16. The bottom surface 101 of the first cleaning tank 10 includes a first contact area 18, and the first cleaning tank 10 is configured to accommodate a first cleaning component 20 of a cleaning robot 200. The bottom surface of the second cleaning tank 12 includes a second contact area 22, and the second cleaning tank 12 is configured to accommodate a second cleaning component 24 of the cleaning robot 200. The second cleaning component 24 is located on the outer periphery of the first cleaning component 20, and the second cleaning component 24 is used at least to clean the cleaning blind spot 206 of the cleaning robot 200. The first scraper 14 is located inside the first cleaning tank 10. The second scraper 16 is located inside the second cleaning tank 12. The first cleaning tank 10 and the second cleaning tank 12 may be connected or not connected. The first scraper 14 and the second scraper 16 are connected to form a third scraper 30, or the first scraper 14 and the second scraper 16 are separated.

[0061] The cleaning tank structure 100 is configured such that: when the first cleaning component 20 is placed in the first cleaning tank 10 and on the first scraper 14, the first contact area 18 is in direct contact with the first cleaning component 20 when it is rotating and not rotating; when the second cleaning component 24 is placed in the second cleaning tank 12 and on the second scraper 16, the second contact area 22 is in direct contact with the second cleaning component 24 when it is rotating and not rotating.

[0062] In the aforementioned cleaning tank structure 100, when the two cleaning components are placed in the corresponding cleaning tank and on the scraper, the contact area can directly contact the cleaning components when they are rotating and not rotating. On the one hand, when cleaning the cleaning components, the cleaning components can rotate, so that the first scraper 14 and the second scraper 16 can effectively clean the first cleaning component 20 and the second cleaning component 24 respectively. On the other hand, the rotating first cleaning component 20 can clean the first contact area 18 and the rotating second cleaning component 24 can clean the second contact area 22, thereby avoiding or reducing the amount of debris remaining on the bottom surface of the cleaning tank, and thus avoiding or reducing the probability of the cleaning tank structure 100 becoming smelly.

[0063] Specifically, please refer to Figure 4 and Figure 4aIn one embodiment, the cleaning tank structure 100 is provided with a first cleaning tank 10, a second cleaning tank 12, and a third cleaning tank 34, which can be adapted to a cleaning robot 200 with dual first cleaning components 20. Two first cleaning components 20 can be provided on the bottom of the cleaning robot 200's body, and a second cleaning component 24 is connected to one of the first cleaning components 20. The rotation axis of each first cleaning component 20 is substantially perpendicular to the bottom of the body, and the rotation axis of the second cleaning component 24 is also substantially perpendicular to the bottom of the body. When the two first cleaning components 20 perform cleaning operations outside the base station 200 and inside the base station, the rotation directions of the two first cleaning components 20 can be the same or opposite. The rotation direction of the second cleaning component 24 can be the same or opposite to the rotation direction of the connected first cleaning component 20; this invention does not specifically limit this. It is understood that in other embodiments, the cleaning tank structure 100 can also be provided with a single first cleaning tank 10, which can be adapted to a cleaning robot 200 with a single first cleaning component 20.

[0064] After the cleaning robot 200 returns to the base station, the two first cleaning components 20 can be placed in the first cleaning tank 10 and the third cleaning tank 34 respectively, and the second cleaning component 24 is placed in the second cleaning tank 12.

[0065] The number of the first scraper blades includes, but is not limited to, one, two, or more. The number of the second scraper blades includes, but is not limited to, one, two, or more. The number of the first scraper blades and the number of the second scraper blades may be the same or different.

[0066] exist Figure 4b In this system, the cleaning robot 200 includes a drive assembly 202, which is connected to a first cleaning component 20. A second cleaning component 24 is connected to the first cleaning component 20 via a connecting component 204. When the first cleaning component 20 moves along the height direction of the cleaning robot 200, it synchronously drives the second cleaning component 24 to reciprocate along the height direction of the cleaning robot 200. When the first and second cleaning components 20 and 24 move upwards along the height direction of the cleaning robot 200, they can be lifted off the ground to facilitate the cleaning robot 200's entry and exit from the base station. The second cleaning component 24 can assist the first cleaning component 20 in cleaning, specifically for cleaning the cleaning blind spots 206 of the cleaning robot 200. The connecting component 204 transmits power from the drive assembly 202 to the second cleaning component 24 to drive its rotation. The connecting component 204 includes, but is not limited to, gears, lead screws, and belts.

[0067] Alternatively, the cleaning tank structure 100 can also be adapted to a cleaning robot 200 that has only a single first cleaning component 20.

[0068] In one embodiment, when the cleaning component of the cleaning robot 200 is cleaning, the cleaning robot 200 can enter the base station, the cleaning component can be placed on the corresponding scraper, and the contact area can directly contact the cleaning component when it is not rotating.

[0069] While the scraper cleans the cleaning components, the rotating cleaning components can also directly contact the contact area. Thus, during the cleaning process, the rotating cleaning components can also clean the contact area, which can avoid or reduce the amount of debris remaining on the bottom surface of the cleaning tank, thereby preventing or reducing the chance of the cleaning tank structure becoming smelly.

[0070] Optionally, in one embodiment, the bottom surface of the entire cleaning tank can be a contact area, that is, the bottom surface of the entire cleaning tank is in direct contact with the rotating and non-rotating cleaning components.

[0071] In one implementation, please refer to Figure 1 The second cleaning tank 12 is connected to the first cleaning tank 10 to form a larger cleaning tank, and the first scraper 14 is connected to the second scraper 16 to form the third scraper 30.

[0072] In one implementation, please refer to Figure 1 The second cleaning tank 12 is connected to the first cleaning tank 10 to form a larger cleaning tank. The first scraper 14 and the second scraper 16 can be separated, that is, the first scraper 14 and the second scraper 16 can be not connected.

[0073] In one embodiment, the second cleaning tank 12 and the first cleaning tank 10 are not connected, and the second cleaning tank 12 and the first cleaning tank 10 can be separately configured as two separate cleaning tanks. The first scraper 14 and the second scraper 16 are spaced apart.

[0074] Please see Figure 1 and Figure 2 In some embodiments, the cleaning tank structure 100 includes a first water inlet 26 and a water outlet 28, and a third scraper 30 connects the first water inlet 26 and the water outlet 28.

[0075] In this way, the cleaning water flowing in from the first water inlet 26 can flow along the third scraper 30, effectively wetting the first cleaning component 20 and the second cleaning component 24, thereby cleaning the first cleaning component 20 and the second cleaning component 24 more effectively.

[0076] Specifically, please refer to Figure 1 and Figure 2In one embodiment, the third scraper 30 is an integral structure. The portion of the third scraper 30 located within the first cleaning tank 10 is the first scraper 14, while the portion located within the second cleaning tank 12 is the second scraper 16. Optionally, the third scraper 30 can be fixed within the cleaning tank or rotatably disposed within the cleaning tank.

[0077] Alternatively, in other embodiments, the first scraper 14 and the second scraper 16 can be two independent parts connected to each other. The first scraper 14 and the second scraper 16 can also be separated.

[0078] Please see Figure 2 and Figure 3 In some embodiments, the cleaning tank structure 100 includes a plurality of third scrapers 30, which together with the bottom surface 101 of the first cleaning tank 10 and the bottom surface of the second cleaning tank 12 form a first water delivery channel 32, which connects to a first water inlet 26 and a water outlet 28.

[0079] In this way, the first cleaning tank 10 and the second cleaning tank 12 can share a water inlet, and the sewage can be smoothly discharged to the water outlet 28 through the first water delivery channel 32.

[0080] Specifically, please refer to Figure 2 and Figure 3 In one embodiment, the cleaning tank structure 100 includes two substantially parallel third scrapers 30, which, together with the bottom surface 101 of the first cleaning tank 10 and the bottom surface of the second cleaning tank 12, form a first water delivery channel 32. One end of the first water delivery channel 32 is located at the edge of the second cleaning tank 12 and communicates with a first water inlet 26, while the other end is located at the edge of the first cleaning tank 10 and communicates with a water outlet 28.

[0081] Optionally, in Figure 2 In the middle, the cleaning tank structure 100 includes two fourth scrapers 46 and a second water inlet 44. The two fourth scrapers 46 and the bottom surface of the third cleaning tank 34 form a third water delivery channel 68, which connects the second water inlet 44 and the water outlet 28.

[0082] Alternatively, in another embodiment, the first water inlet 26 is located at the edge of the first cleaning tank 10, and the water outlet 28 may be located at the edge of the second cleaning tank 12.

[0083] Understandably, the number of fourth scrapers 46 is not limited to two; it can be a single scraper or more than two.

[0084] exist Figure 2In the cleaning tank structure 100, the first water inlet 26 can be located on the left rear side. The water outlet 28 can be located on the right front side. Compared to the first water delivery channel 32 and the second water delivery channel 48, the first water inlet 26 is located at a higher position, and the water outlet 28 is located at a lower position. The cleaning water entering through the first water inlet 26 cleans the first cleaning component 20 and the second cleaning component 24, and the wastewater can flow to the water outlet 28 through the first water delivery channel 32 under the action of gravity. The cleaning water entering through the second water inlet cleans the other first cleaning component 20, and the wastewater can flow to the water outlet 28 through the second water delivery channel 48 under the action of gravity.

[0085] Please see Figure 1 In some embodiments, the second cleaning tank 12 is located on the side of the first cleaning tank 10 away from the water outlet 28.

[0086] This facilitates the spatial configuration of the cleaning tank structure 100.

[0087] Specifically, since the second cleaning tank 12 is located on the side of the first cleaning tank 10 away from the water outlet 28, the distance between the water outlet 28 and the second cleaning tank 12 is greater, reducing the space constraints on the design of the first cleaning tank 10 and enabling the design of the first cleaning tank 10 to meet the cleaning needs of the first cleaning component 20. Moreover, when cleaning water flows into the second cleaning tank 12 from the first water inlet 26, the cleaning water can flow a longer distance in the first cleaning tank 10 before flowing into the water outlet 28, thereby further effectively cleaning the first cleaning component 20.

[0088] Please see Figure 2 In one embodiment, the second cleaning tank 12 and the water outlet 28 are located on both sides of the first cleaning tank 10 in the radial direction.

[0089] Optionally, in Figure 1 In the cleaning tank structure 100, a third cleaning tank 34 is also included for accommodating another first cleaning component 20 of the cleaning robot 200. The third cleaning tank 34 is located to the right of the first cleaning tank 10, and the first cleaning tank 10 and the third cleaning tank 34 are connected, with a water outlet 28 provided at the connection point. Thus, the first cleaning tank 10, the second cleaning tank 12, and the third cleaning tank 34 can share a single water outlet 28. The second cleaning tank 12 is located on the side of the first cleaning tank 10 opposite to the water outlet 28 and the third cleaning tank 34.

[0090] Please see Figure 3 In some embodiments, the sidewall of the first cleaning tank 10 has a first notch 36, and the sidewall of the second cleaning tank 12 has a second notch 38, with the edge of the first notch 36 connecting to the edge of the second notch 38.

[0091] In this way, the first cleaning tank 10 and the second cleaning tank 12 can be connected.

[0092] Specifically, please refer to Figure 3 In one embodiment, the first notch 36 and the second notch 38 are opposite each other and are the same size. The first scraper 14 and the second scraper 16 are connected to form a third scraper 30, which passes through the first notch 36 and the second notch 38. The first water inlet 26, the second notch 38, the first notch 36 and the water outlet 28 are arranged sequentially along the length of the third scraper 30.

[0093] The first cleaning tank 10 and the second cleaning tank 12 are connected by a notch in the side wall, which allows cleaning water to flow smoothly from the second cleaning tank 12 to the first cleaning tank 10, or from the first cleaning tank 10 to the second cleaning tank 12, while avoiding the residue of contaminants at the notch to a certain extent.

[0094] Optionally, the sidewall of the first cleaning tank 10 also has a third notch 40, which is located on the side of the sidewall of the first cleaning tank 10 away from the first notch 36, and the first cleaning tank 10 is connected to the water outlet 28 through the third notch 40. The sidewall of the third cleaning tank 34 has a fourth notch 42, the edge of the third notch 40 is connected to the edge of the fourth notch 42, and the third cleaning tank 34 is connected to the water outlet 28 through the fourth notch 42.

[0095] Please see Figure 1 In some embodiments, the first cleaning tank 10 includes a first sidewall 50 and a second sidewall 52. One end of the first sidewall 50 and one end of the second sidewall 52 are spaced apart to form a first notch 36. The first sidewall 50 is closer to the inlet 54 of the cleaning tank structure 100 than the second sidewall 52.

[0096] The diameter of the circle containing the first sidewall 50 is greater than the diameter of the circle containing the second sidewall 52, and the width E1 of the first sidewall 50 in the horizontal direction is greater than the width E2 of the second sidewall 52 in the horizontal direction.

[0097] This helps to overcome the offset error when the cleaning robot returns to its station 200 times.

[0098] Specifically, please refer to Figure 1 The first sidewall 50 is the front sidewall, and the second sidewall 52 is the rear sidewall. When the cleaning robot 200 returns to the station, it needs to cross the first sidewall 50 to enter the cleaning tank structure 100. Because the first sidewall 50 is closer to the entrance 54, its horizontal width E1 is larger, which helps the cleaning tank structure 100 overcome the offset error when the cleaning robot 200 returns to the station, making it easier for the cleaning robot 200 to enter the station.

[0099] Optionally, the second cleaning tank 12 includes a third sidewall 56 and a fourth sidewall 58. One end of the third sidewall 56 and one end of the fourth sidewall 58 are spaced apart to form a second notch 38. The third sidewall 56 is closer to the inlet 54 of the cleaning tank structure 100 than the fourth sidewall 58. The diameter of the circle containing the third sidewall 56 may be equal to, greater than, or less than the diameter of the circle containing the fourth sidewall 58, and the width of the third sidewall 56 in the horizontal direction may be equal to, greater than, or less than the width of the fourth sidewall 58 in the horizontal direction.

[0100] Optionally, the third cleaning tank 34 includes a fifth sidewall 60 and a sixth sidewall 62. One end of the fifth sidewall 60 and one end of the sixth sidewall 62 are spaced apart to form a fourth notch 42. The fifth sidewall 60 is closer to the inlet 54 of the cleaning tank structure 100 than the sixth sidewall 62. The diameter of the circle containing the fifth sidewall 60 is larger than the diameter of the circle containing the sixth sidewall 62, and the width of the fifth sidewall 60 in the horizontal direction is larger than the width of the sixth sidewall 62 in the horizontal direction. This facilitates the entry of the two first cleaning components 20 of the cleaning robot 200 into the cleaning tank structure 100.

[0101] Please see Figure 2 In some embodiments, the cleaning tank structure 100 includes a first baffle 64 and a second baffle 66, which form a first cleaning tank 10. The first sidewall 50 is the sidewall of the first baffle 64 facing the first cleaning tank 10, and the second sidewall 52 is the sidewall of the second baffle 66 facing the first cleaning tank 10. The height of the second baffle 66 is greater than the height of the first baffle 64.

[0102] Thus, on the one hand, it makes it easier for the cleaning robot 200 to enter the station, and on the other hand, the higher second barrier 66 can also prevent or reduce sewage splashing out of the cleaning tank structure 100.

[0103] Specifically, the first baffle 64 is the front baffle, and the second baffle 66 is the rear baffle. The first baffle 64 is closer to the entrance 54, and the cleaning robot 200 needs to cross the first baffle 64 to enter the cleaning tank structure 100. The first baffle 64 is relatively low, thus its lower position reduces the resistance when the cleaning robot returns to the station, making it easier for the cleaning robot 200 to enter the station. The second baffle 66 is further away from the entrance 54. After the cleaning robot 200 returns to the station, the first cleaning component 20 can be placed inside the first cleaning tank. The higher second baffle 66 can prevent or reduce the spillage of wastewater from inside the cleaning tank structure 100 onto the outside of the cleaning tank structure 100, avoiding additional cleaning burden for the user.

[0104] The diameter of the circle containing the first baffle 64 is larger than the diameter of the circle containing the second baffle 66. The first cleaning component 20 is located within the first cleaning groove 10 formed by the second baffle 66. The edge of the first cleaning component 20 is close to the second baffle 66. The second baffle 66 exerts a larger pressure on the first cleaning component 20, which can better clean the first cleaning component 20.

[0105] exist Figure 2 In this design, both the first baffle 64 and the second baffle 66 are arc-shaped to form a substantially circular first cleaning groove 10, which can be adapted to the rotating first cleaning component 20. It is understood that this invention does not specifically limit the shapes of the first cleaning groove 10 and the first cleaning component 20.

[0106] Optionally, both the first stop bar 64 and the second stop bar 66 can be soft stop bars. Optionally, the first stop bar 64 can be a soft stop bar, and the second stop bar 66 can be a hard stop bar. Optionally, both the first stop bar 64 and the second stop bar 66 can be hard stop bars. Optionally, the soft stop bar can be made of materials such as rubber (e.g., TPU) or silicone. Optionally, the hard stop bar can be made of materials such as plastic (e.g., ABS, PC).

[0107] Optionally, in one embodiment, the first cleaning tank 10, the second cleaning tank 12 and the third cleaning tank 34 may be formed by the first recess, the second recess and the third recess provided on the top surface of the base, respectively. The first sidewall 50 and the second sidewall 52 may be the sidewalls of the first recess, the third sidewall 56 and the fourth sidewall 58 may be the sidewalls of the second recess, and the fifth sidewall 60 and the sixth sidewall 62 may be the sidewalls of the third recess.

[0108] Please see Figures 1 to 3 In some embodiments, the connection between the second sidewall 52 and the edge of the second notch 38 is closer to the center of the first cleaning tank 10 than the connection between the first sidewall 50 and the edge of the second notch 38. Along the rotation direction of the first cleaning component 20, the connection between the second sidewall 52 and the edge of the second notch 38 is located behind the connection between the first sidewall 50 and the edge of the second notch 38.

[0109] In this way, the cleaning effect of the first cleaning component 20 can be improved.

[0110] Specifically, the connection between the second sidewall 52 and the fourth sidewall 58 is referred to as the second connection 76, and the connection between the edge of the first sidewall 50 and the third sidewall 56 is referred to as the first connection 74.

[0111] Optionally, please combine Figure 1 , Figure 2 and Figure 4The connection between the sixth sidewall 62 and the edge of the second water inlet 44 is closer to the center of the third cleaning tank 34 than the connection between the fifth sidewall 60 and the edge of the second water inlet 44. Along the rotation direction of the first cleaning component 20 on the right, the connection between the sixth sidewall 62 and the edge of the second water inlet 44 is located behind the connection between the fifth sidewall 60 and the edge of the second water inlet 44. The connection between the sixth sidewall 62 and the edge of the second water inlet 44 is referred to as the fourth connection 80, and the connection between the fifth sidewall 60 and the edge of the second water inlet 44 is referred to as the third connection 78.

[0112] Please combine Figures 1 to 4 For the first cleaning tank, the second connection 76 is located behind the first connection 74 in a clockwise direction R1. When the first cleaning component 20 located in the first cleaning tank 10 rotates clockwise in a clockwise direction R1 during cleaning, the first cleaning component 20 moves from the part of the first cleaning tank 10 surrounded by the first side wall 50 to the part of the first cleaning tank 10 surrounded by the second side wall 52. The fibers 82 of the first cleaning component 20 can then be patted onto the second connection 76, which is closer to the center of the first cleaning tank 10. This allows the wastewater and debris on the first cleaning component 20 to be patted off and fall into the first cleaning tank 10.

[0113] For the third cleaning tank, the fourth connection 80 is located behind the third connection 78 in a counterclockwise direction R2. The first cleaning component 20 in the third cleaning tank 34 on the right rotates counterclockwise in a counterclockwise direction R2 during cleaning. When the first cleaning component 20 moves from the part of the third cleaning tank 34 surrounded by the fifth side wall 60 to the part of the third cleaning tank 34 surrounded by the sixth side wall 62, the lint 82 of the first cleaning component 20 can beat against the fourth connection 80, which is closer to the center of the third cleaning tank 34. This allows the sewage and debris on the first cleaning component 20 to be knocked off and fall into the third cleaning tank 34.

[0114] In summary, this can improve the cleaning effect of the two primary cleaning components 20.

[0115] Furthermore, the second connection 76 is closer to the center of the first cleaning tank 10 than the first connection 74. Along the rotation direction of the first cleaning component 20, the second connection 76 is located behind the first connection 74, allowing for better compression of the first cleaning component 20 and scraping off debris. Large particles of debris can be collected through the central first water delivery channel 32 and directed to the water outlet 28. Optionally, since the edges of the first cleaning component 20 tend to be dirtier, appropriate extrusion elements can be provided along the edges to enhance the cleaning effect. The fourth connection 80, being closer to the center of the third cleaning tank 34 than the third connection 78, achieves the same effect.

[0116] Optionally, please combine Figure 2 The cleaning tank structure 100 also includes a third baffle 84 and a fourth baffle 86, which form a second cleaning tank 12. A third sidewall 56 is the sidewall of the third baffle 84 facing the second cleaning tank 12, and a fourth sidewall 58 is the sidewall of the fourth baffle 86 facing the second cleaning tank 12. The height of the fourth baffle 86 is greater than the height of the third baffle 84. The higher fourth baffle 86 can prevent or reduce wastewater from spilling outside the cleaning tank structure 100, avoiding additional cleaning burden for the user.

[0117] Similarly, the aforementioned beneficial effects also apply to the third cleaning tank 34.

[0118] Please combine Figure 2 In some embodiments, the bottom surface 101 of the first cleaning tank 10 includes a non-contact area 88, and the cleaning tank structure 100 is configured as follows:

[0119] When the first cleaning component 20 is placed in the first cleaning tank, the vertical distance W between the non-contact area 88 and the bottom surface of the first cleaning component 20 is in the range of (0, 3] mm.

[0120] Thus, during the cleaning process of the first cleaning component 20, when the first cleaning component 20 is placed on the first scraper 14, the first cleaning component 20 can drive the water flow to the non-contact area 88 to clean the non-contact area 88 when it rotates. At the same time, increasing the non-contact area 88 can also reduce the friction between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10, reduce energy consumption, and can be adapted to low-power motors.

[0121] Specifically, in one embodiment, when the first cleaning component 20 is placed in the first cleaning tank, the bottom surface 101 of the first cleaning tank 10 also includes a non-contact area 88. While the first scraper 14 scrapes and washes the first cleaning component 20, the vertical distance W between the non-contact area 88 of the bottom surface 101 of the first cleaning tank 10 and the bottom surface of the first cleaning component 20 ranges from (0, 3] mm. During the cleaning process of the first cleaning component 20, the first cleaning component 20, when rotating, can cause water to be thrown towards the non-contact area 88 to clean it. For example, the vertical distance W between the non-contact area 88 of the bottom surface 101 of the first cleaning tank 10 and the bottom surface of the first cleaning component 20 can be 3 mm, 2.8 mm, 2.5 mm, 2 mm, 1.5 mm, 1 mm, or other values ​​less than or equal to 3 mm. The vertical distance W between the non-contact area 88 of the bottom surface 101 of the first cleaning tank 10 and the bottom surface of the first cleaning component 20 can be specifically determined according to actual needs, and this utility model does not impose specific limitations on it.

[0122] Optionally, please combine Figure 5The first cleaning component 20 can be a mop, and the second cleaning component 24 can be a mop. The first cleaning component 20 includes a bristle 82 and a base 90. The bristle 82 is located at the bottom of the base 90. The vertical distance W between the non-contact area 88 of the bottom surface 101 of the first cleaning tank 10 and the bottom surface of the first cleaning component 20 can be the vertical distance between the non-contact area 88 and the bottom surface of the bristle 82.

[0123] Optionally, the mop of the first cleaning component 20 may include, but is not limited to, a rotary mop, a flatbed mop, and a tracked mop. The mop of the second cleaning component 24 may include, but is not limited to, a rotary mop, a flatbed mop, and a tracked mop. The type of the first cleaning component 20 and the type of the second cleaning component 24 may be the same or different.

[0124] Optionally, in one embodiment, the first contact area 18 may be an inclined plane, and the non-contact area 88 may also be an inclined plane, with the slope of the non-contact area 88 being greater than the slope of the first contact area 18. In one embodiment, the first contact area 18 may be a horizontal plane, and the non-contact area 88 may also be a horizontal plane, with the first contact area 18 and the non-contact area 88 at different heights. In one embodiment, the first contact area 18 may be a horizontal plane, and the non-contact area 88 may be an inclined plane. In one embodiment, the first contact area 18 may be an inclined plane, and the non-contact area 88 may be a horizontal plane. In one embodiment, the first contact area 18 may be an inclined plane, and the non-contact area 88 may also be an inclined plane, with the slope of the non-contact area 88 equal to the slope of the first contact area 18. The first contact area 18 may be a curved surface or an arc surface, and the non-contact area 88 may also be a curved surface or an arc surface. The shape and tilt angle of the second contact area 22 may be consistent with or different from those of the first contact area 18.

[0125] Please combine Figure 7 As can be seen from the effect diagram, when the vertical distance W between the non-contact area 88 and the bottom surface of the first cleaning component 20 is in the range of (0, 3] mm, even in areas where the first cleaning component 20 does not contact the bottom surface 101 of the first cleaning tank 10, the rotating first cleaning component 20 can still achieve the desired cleaning effect on the non-contact area 88, reducing the probability of odor in the cleaning tank structure. Similarly, the above-mentioned beneficial effects also apply to the third cleaning tank 34.

[0126] Specifically, in Figure 7In the diagram, y represents the vertical compression amount between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10, in mm. When y < 0, it indicates that the first cleaning component 20 is isolated from the bottom surface 101 of the first cleaning tank 10. In this case, the absolute value of y represents the isolation amount (i.e., the vertical distance W). F represents the cleaning effect of the cleaning robot 200 after one self-cleaning cycle. In each test, 5g of yellow mud is sprinkled on the ground. After the cleaning robot 200 returns to its station and performs one self-cleaning cycle, the weight z (in g) of dirt added to the cleaning tank structure 100 is measured. F = 1 - z / 5 × 100%. When F >= 90% after one self-cleaning cycle, the cleaning effect meets the cleaning requirements.

[0127] from Figure 7 It can be seen that when y>=-3 (i.e., the vertical distance W is in the range of (0,3]mm), the cleaning effect F>=90%, which meets the cleaning requirements. When -3<=y<0, the first cleaning component 20 will drive the water in the cleaning tank structure 100 to flow when rotating, and the water flow will rinse the cleaning tank structure 100, thereby achieving the effect of cleaning the cleaning tank structure 100. When y>0, there is a squeezing between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10, and the friction between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 makes the cleaning effect meet the requirements. Since the first cleaning component 20 is composed of a base 90 and a bristle 82, and the base 90 is a hard material that is difficult to squeeze, the vertical squeezing amount between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 cannot be measured to the thickness of the first cleaning component 20. The test data is shown in Table 1 below. The smaller z is, the less yellow mud remains in the cleaning tank structure 100, and the better the cleaning effect on the cleaning tank structure 100.

[0128] Table 1

[0129]

[0130]

[0131] Similarly, the data in Table 1 also applies to the other first cleaning component 20 and the third cleaning tank 34.

[0132] In some embodiments, the cleaning tank structure 100 includes a first water inlet 26 and a water outlet 28. The bottom surface 101 of the first cleaning tank 10 connects the first water inlet 26 and the water outlet 28. The bottom surface 101 of the first cleaning tank 10 is inclined from the first water inlet 26 to the water outlet 28. The bottom surface 101 of the first cleaning tank 10 is conical. The non-contact area 88 includes at least a portion of a circular area. The circular area is a circular area formed with the center of the bottom surface 101 of the first cleaning tank 10 as the center and with a preset radius.

[0133] In this way, the bottom surface 101 of the first cleaning tank 10 can be formed by using a cone shape, and the cleaning effect requirements of the non-contact area 88 can be met.

[0134] Specifically, the bottom surface 101 of the conical first cleaning tank 10 is inclined along the direction of the first water inlet 26 toward the water outlet 28, and the lowest point of the bottom surface 101 of the first cleaning tank 10 is the position connected to the water outlet 28. When the first cleaning component 20 is placed in the first cleaning tank 10, the first cleaning component 20 is spaced apart from at least a portion of the circular area.

[0135] Please combine Figure 2 Let's take the first cleaning tank 10 as an example. Since the circular area is a circular area formed with the center O of the bottom surface 101 of the first cleaning tank 10 as its center and with a preset radius, and the bottom surface 101 of the first cleaning tank 10 is conical, the circular area in the middle of the bottom surface 101 of the first cleaning tank 10 is lower than the edge of the bottom surface 101 of the first cleaning tank 10. Compared to the edge of the bottom surface 101 of the first cleaning tank 10, this circular area forms a depression, which can accumulate a certain amount of water flow, thereby cleaning the non-contact area 88 and meeting the cleaning effect requirements. It can be understood that the preset radius of the circular area is smaller than the radius of the first cleaning tank 10.

[0136] Optionally, the first cleaning component 20 has an opening in the middle, and the bottom surface 101 of the first cleaning tank 10 exposed by the opening can also be cleaned by the water flow thrown out by the rotating first cleaning component 20 or the fluff 82 of the first cleaning component 20, thus meeting the cleaning effect requirements. Optionally, in other embodiments, the first cleaning component 20 may not have an opening in the middle.

[0137] The preset radius can be specifically limited according to requirements, but this utility model does not make specific limitations in this regard.

[0138] Similarly, the aforementioned beneficial effects also apply to the third cleaning tank 34.

[0139] Please see Figure 2 In some embodiments, the first scraper 14 divides the bottom surface 101 of the first cleaning tank 10 into a first bottom surface region 94 and a second bottom surface region 96. The non-contact area 88 includes one or a combination of the first non-contact area 98 and the second non-contact area 102. The first non-contact area 98 is a part of a first circular area 104, which is a circular area centered on the center of the first bottom surface region 94 and with a first preset radius. The second non-contact area 102 is a part of a second circular area 106, which is a circular area centered on the center of the second bottom surface region 96 and with a second preset radius.

[0140] In this way, the bottom surface 101 of the first cleaning tank 10 can be divided into areas using the first scraper 14, and the first bottom surface area 94 and the second bottom surface area 96 can be configured separately to meet the cleaning effect requirements of the non-contact area 88.

[0141] Optionally, the first scraper 14 can be fixed inside the first cleaning tank 10, or it can be detachably connected to the bottom surface 101 of the first cleaning tank 10.

[0142] Optionally, the first cleaning tank 10 is provided with two first scraper strips 14, which divide the bottom surface 101 of the first cleaning tank 10 into a first bottom surface area 94 and a second bottom surface area 96. In the figure, the first bottom surface area 94 is the front bottom surface area, and the second bottom surface area 96 is the rear bottom surface area.

[0143] Optionally, the non-contact area 88 includes a combination of the first non-contact area 98 and the second non-contact area 102. Optionally, the non-contact area 88 includes either the first non-contact area 98 or the second non-contact area 102.

[0144] The first base region 94 is a part of the first conical base, and the second base region 96 is a part of the second conical base. Optionally, in the figure, the radius of the circle containing the first base region 94 is greater than the radius of the circle containing the second base region 96. Optionally, the radius of the circle containing the first base region 94 is less than or equal to the radius of the circle containing the second base region 96.

[0145] The first non-contact area 98 is part of the first circular area 104. Since the first circular area 104 is a circular area centered on the center of the first bottom area 94 and with a first preset radius, and the first bottom area 94 is part of a conical base, the first circular area 104 in the middle of the first bottom area 94 is lower than its edge. Compared to the edge of the first bottom area 94, this first circular area 104 forms a depression, which can accumulate a certain amount of water flow, thereby cleaning the first non-contact area 98 and meeting the cleaning effect requirements. It can be understood that the first preset radius is smaller than the radius of the first bottom area 94.

[0146] The second non-contact area 102 is a part of the second circular area 106. Since the second circular area 106 is a circular area centered on the center of the second bottom area 96 and with a second preset radius, and the second bottom area 96 is part of a conical base, the second circular area 106 in the middle of the second bottom area 96 is lower than its edge. Compared to the edge of the second bottom area 96, this second circular area 106 forms a depression, which can accumulate a certain amount of water flow, thereby cleaning the second non-contact area 102 and meeting the cleaning effect requirements. It can be understood that the second preset radius is smaller than the radius of the second bottom area 96.

[0147] Optionally, the first preset radius is equal to the second preset radius, and the center of the first circular region 104 coincides with the center of the second circular region 106. It is understood that in other embodiments, the first preset radius and the second preset radius may not be equal, and the center of the first circular region 104 and the center of the second circular region 106 may not coincide.

[0148] Optionally, the first scraper 14 in the first cleaning tank 10 is not limited to two, but can be one or more.

[0149] Similarly, the aforementioned beneficial effects also apply to the third cleaning tank 34.

[0150] Please see Figure 10 In some embodiments, the cleaning tank structure 100 includes a base 92, on which a first cleaning tank 10 and a second cleaning tank 12 are provided.

[0151] Thus, the base 92 can provide an installation structure for the cleaning tank structure 100, making it convenient to install the cleaning tank structure 100.

[0152] Specifically, the base 92 can be similar to an elongated disc. The cleaning tank structure 100 can be mounted on the base station 200 via the base 92. Figure 2 In the middle, the base 92 is provided with a first cleaning tank 10, a second cleaning tank 12 and a third cleaning tank 34. The side walls of the first cleaning tank 10, the second cleaning tank 12 and the third cleaning tank 34 can be connected, and the first cleaning tank 10, the second cleaning tank 12 and the third cleaning tank 34 are interconnected. Thus, the first cleaning tank 10, the second cleaning tank 12 and the third cleaning tank 34 can share a single water outlet 28.

[0153] Optionally, the first cleaning tank 10, the second cleaning tank 12, and the third cleaning tank 34 can also be set independently. Each of the first cleaning tank 10 and the third cleaning tank 34 is provided with two scrapers, which are arranged symmetrically. Optionally, the base 92 can be connected to the first cleaning tank 10, the third cleaning tank 34, and the scrapers to form an integrated structure.

[0154] In some embodiments, the cleaning tank structure is configured such that, when the first cleaning component is placed in the first cleaning tank, the compression amount between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 is in the range of [0, T) mm, where T is the thickness of the first cleaning component 20.

[0155] Thus, the amount of pressure exerted by the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 meets the requirements for cleaning effect.

[0156] Specifically, please refer to Figure 6 The thickness T of the first cleaning component 20 includes the length V2 of the fibers 82 and the thickness V3 of the base 90. The greater the pressure exerted between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10, the greater the friction between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10, and the better the cleaning effect. It should be noted that when the pressure exerted between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 is close to the thickness T of the first cleaning component 20, the friction between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 is relatively large. At this time, it is still within the range where the first cleaning component 20 can rotate (that is, the motor of the cleaning robot 200 can still drive the first cleaning component 20 to rotate), and it will not affect the cleaning of the first cleaning component 20.

[0157] Optionally, in some examples, the amount of pressure exerted between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 can be 0 mm, (1 / 6×T) mm, (2 / 6×T) mm, (3 / 6×T) mm, (4 / 6×T) mm, (5 / 6×T) mm, or other values ​​within [0,T). This invention does not specifically limit this. A pressure of 0 mm between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 indicates that the fibers 82 are in contact with the contact area of ​​the bottom surface 101 of the first cleaning tank 10 but are not being compressed.

[0158] Similarly, the aforementioned beneficial effects also apply to the third cleaning tank 34.

[0159] In some embodiments, the cleaning tank structure 100 is configured such that, when the first cleaning component 20 is placed inside the first cleaning tank 10, the horizontal distance U between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 ranges from (0, 8] mm.

[0160] In this way, the water carried on the first cleaning component 20 is thrown onto the side wall of the first cleaning tank 10 under the action of centrifugal force, thereby cleaning the side wall of the first cleaning tank 10.

[0161] Specifically, when the first cleaning component 20 is placed in the first cleaning tank 10 and rotated on the first scraper 14 for cleaning, the edge of the first cleaning component 20 may contact a portion of the side wall of the first cleaning tank 10 (e.g., Figure 5 The front sidewall of the first cleaning tank 10 shown maintains a certain horizontal distance. The horizontal distance U between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 ranges from (0, 8] mm. For example, the horizontal distance U between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 can be 8 mm, 7.8 mm, 7.5 mm, 6 mm, 5.5 mm, 5 mm, or other values ​​of (0, 8] mm. The horizontal distance U between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 can be specifically determined according to actual needs, and this utility model does not make specific limitations in this regard.

[0162] When the horizontal distance U between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 is in the range of (0, 8] mm, when the first cleaning component 20 rotates and cleans on the first scraper 14, the water carried on the first cleaning component 20 is thrown onto the side wall of the first cleaning tank 10 under the action of centrifugal force. The water can clean the side wall of the first cleaning tank 10, thereby achieving the cleaning of the side wall of the first cleaning tank 10. In addition, when the horizontal distance U between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 is in the range of (0, 8] mm, it is also beneficial for the cleaning robot 200 to place the first cleaning component 20 in the first cleaning tank 10, making it easier to position.

[0163] Please combine Figure 8 As can be seen from the effect diagram, when the horizontal distance U between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 is in the range of (0, 8] mm, even if the edge of the first cleaning component 20 does not contact the side wall of the first cleaning tank 10, the rotating first cleaning component 20 can still achieve the desired cleaning effect on the non-contacting side wall area of ​​the first cleaning tank 10, reducing the probability of the cleaning tank structure 100 developing an odor. Similarly, the above-mentioned beneficial effects also apply to the third cleaning tank 34.

[0164] Specifically, in Figure 8 In the diagram, x represents the horizontal compression amount between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 (or the side of the first cleaning tank 10 if there is a baffle), in mm. When x < 0, it indicates that the edge of the first cleaning component 20 is isolated from the side wall of the first cleaning tank 10. The absolute value of x represents the isolation amount, i.e., the horizontal distance U. F represents the cleaning effect of the cleaning robot 200 after one self-cleaning cycle. In each test, 5g of yellow mud is sprinkled on the ground. After the cleaning robot 200 returns to its station and performs one self-cleaning cycle, the weight z (in g) of dirt added to the first cleaning tank 10 is measured. F = 1 - z / 5 × 100%. When F >= 90% after one self-cleaning cycle, the cleaning effect meets the cleaning requirements.

[0165] In this test, the y-value is fixed, for example, y = 1 mm, from Figure 8It can be seen that when -8 <= x <= 10, the cleaning effect F >= 90%, which meets the cleaning requirements. When x < -8, the distance between the side wall of the first cleaning tank 10 and the edge of the first cleaning component 20 is too far. When the first cleaning component 20 rotates, it cannot effectively clean the side wall of the first cleaning tank 10 by relying on water flow and lint 82, resulting in blind spots and poor cleaning effect. When x > 10, the first cleaning component 20 is excessively squeezed against the side wall of the first cleaning tank 10, causing the first cleaning component 20 to bulge, resulting in some areas separating from the bottom surface 101 of the first cleaning tank 10. The isolation amount is very large, affecting the cleaning effect. The test data is shown in Table 2 below.

[0166] Table 2 (y = 1 mm (1 / 6.5 of the thickness of the first cleaning component))

[0167] x z F -10 1 80％ -8 0.5 90％ -4 0 100％ 0 0 100％ 4 0 100％ 8 0.2 96％ 10 0.48 90.4％ 12 1.2 76％

[0168] Similarly, the data in Table 2 also apply to the other first cleaning component 20 and the third cleaning tank 34.

[0169] In some embodiments, the cleaning tank structure 100 is configured such that, when the first cleaning component 20 is placed inside the first cleaning tank 10, the amount of compression between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 ranges from (0, 10] mm.

[0170] In this way, the squeezing amount between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 can achieve the desired cleaning effect.

[0171] Specifically, when the first cleaning component 20 is placed in the first cleaning tank 10 and rotated on the first scraper 14 for cleaning, the edge of the first cleaning component 20 may contact a portion of the side wall of the first cleaning tank 10 (e.g., Figure 5 The first cleaning component 20 is pressed against the rear sidewall of the first cleaning tank 10 shown. Optionally, the amount of pressure between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 ranges from (0, 10) mm. For example, the amount of pressure between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 can be 10 mm, 9.8 mm, 9.5 mm, 9 mm, 8.5 mm, 8 mm, or other values ​​of (0, 10) mm. The amount of pressure between the edge of the first cleaning component 20 and the sidewall of the first cleaning tank 10 can be specifically determined according to actual needs, and this utility model does not impose specific limitations on it.

[0172] The range of the squeezing amount between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 is (0, 10] mm. When the squeezing amount between the first cleaning component 20 and the side wall of the first cleaning tank 10 reaches a large amount, the friction between the first cleaning component 20 and the side wall of the first cleaning tank 10 is large, which is beneficial to the mutual cleaning of the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10. It should be noted that when the maximum squeezing amount between the edge of the first cleaning component 20 and the side wall of the first cleaning tank 10 is (0, 10] mm, the first cleaning component 20 can still rotate (that is, the motor of the cleaning robot 200 can still drive the first cleaning component 20 to rotate), which will not cause the motor to operate under overload, nor will it affect the cleaning of the first cleaning component 20's rotation.

[0173] Similarly, the aforementioned beneficial effects also apply to the third cleaning tank 34.

[0174] Optionally, the first cleaning component 20 has a fixed amount of pressure in the vertical direction, and the maximum amount of pressure and maximum separation between the first cleaning component 20 and the side wall of the first cleaning tank 10 in the horizontal direction are investigated.

[0175] Please combine Figure 9 Since the vertical squeezing amount of the first cleaning component 20 has a more important effect on the cleaning effect, when the vertical squeezing amount of the first cleaning component 20 is relatively large (close to the critical value, y = 6.0 mm, the squeezing amount is equal to 6.0 / 6.5 of the thickness of the first cleaning component 20), the first cleaning component 20 meets the cleaning requirements in the horizontal x range, and explores whether the y value has an impact on the x range that meets the cleaning requirements.

[0176] from Figure 9 It can be seen that when y = 6.0 mm, the cleaning effect F >= 90% when -8 <= x <= 10, which meets the cleaning requirements. Comparing with Table 1, it is found that the y value has no significant impact on the x range that meets the cleaning requirements. Since the y value mainly affects the cleaning effect in the vertical direction, when the y value meets the cleaning requirements, it will not significantly affect the effective value of x. The test data is shown in Table 3 below.

[0177] Table 3 (y = 6.0 mm) (6.0 / 6.5 of the thickness of the first cleaning component)

[0178] x z F -10 1 80％ -8 0.4 92％ -4 0 100％ 0 0 100％ 4 0 100％ 8 0.1 98％ 10 0.45 91％ 12 1.3 74％

[0179] Optionally, when the first cleaning component 20 and the side wall of the first cleaning tank 10 reach the maximum squeezing amount, and the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10 reach the maximum squeezing amount, the first cleaning component 20 can still rotate (that is, the motor of the cleaning robot 200 can still drive the first cleaning component 20 to rotate), without causing the motor to operate under overload, and without affecting the cleaning of the first cleaning component 20 rotating.

[0180] It should be noted that the test data is the average value obtained by taking the thickness of the first cleaning component 20 in the above test, which is 6.5mm.

[0181] Similarly, the data in Table 3 also apply to the other first cleaning component 20 and the third cleaning tank 34.

[0182] In some embodiments, the cleaning tank structure 100 includes a first water inlet 26 and a water outlet 28. The first cleaning tank 100 is provided with a plurality of first scrapers 14. The plurality of first scrapers 14 and the bottom surface 101 of the first cleaning tank 10 form a second water delivery channel 48. The second water delivery channel 48 connects the first water inlet 26 and the water outlet 28.

[0183] Thus, the first water inlet 26 can deliver clean water through the second water delivery channel 48, and at the same time, the wastewater after cleaning can be discharged from the water outlet 28 through the second water delivery channel 48.

[0184] Specifically, in Figure 3 In the first water delivery channel 32, the second water delivery channel 48 is part of the first water delivery channel 32. The second cleaning tank 12 is provided with a plurality of second scrapers 16. The plurality of second scrapers 16 and the bottom surface of the second cleaning tank 12 form a fourth water delivery channel 70. The fourth water delivery channel 70 is connected to the second water delivery channel 48 and together constitutes the first water delivery channel 32.

[0185] In some embodiments, the second water delivery channel 48 includes a first channel 108 and a second channel 110, which are connected sequentially along the direction from the first water inlet 26 to the water outlet 28. The depth of the second channel 110 is greater than or equal to the depth of the first channel 108 compared to the first water inlet 26.

[0186] Thus, the second channel 110 is deeper, avoiding secondary contamination caused by the first cleaning component 20 within the second channel 110.

[0187] Specifically, the second water delivery channel may include a connecting section channel 112, which is inclined between the first section channel 108 and the second section channel 110. Along the direction from the first inlet hole 26 to the outlet hole 28, the first section channel 108, the connecting section channel 112, and the second section channel 110 are connected sequentially. Along the direction from the first inlet hole 26 to the outlet hole 28, the depth of the connecting section channel 112 may be greater than or equal to the depth of the first section channel 108, and the depth of the second section channel 110 may be greater than or equal to the depth of the connecting section channel 112.

[0188] Alternatively, in one embodiment, the connecting channel 112 may be omitted, and the first channel 108 may be directly connected to the second channel 110.

[0189] In one embodiment, when the first cleaning component 20 rotates so that the first scraper 14 scrapes and washes the first cleaning component 20, the fibers 82 of the first cleaning component 20 can be located in the first channel 108. The clean water in the first channel 108 can clean the fibers 82 of the first cleaning component 20. The wastewater after cleaning can flow through the connecting channel 112 to the second channel 110. The second channel 110 is deeper, so that the first cleaning component 20 or the fibers 82 of the first cleaning component 20 cannot come into contact with the wastewater in the second channel 110, thereby avoiding secondary pollution caused by the first cleaning component 20 in the second channel 110.

[0190] Furthermore, the first scraper 14 can scrape the debris (solid debris such as particles, filaments, adhesives, and fragments; liquid debris such as sewage) attached to the first cleaning component 20 into the second water delivery channel. The water in the second water delivery channel flows out quickly into the outlet hole 28 (the outlet hole 28 can be equipped with a filter to filter debris), thereby achieving an effective and high-speed scraping effect. This avoids scraping the debris onto the bottom surface 101 area of ​​other first cleaning tanks 10. Since the water flow speed on the bottom surface 101 area of ​​other first cleaning tanks 10 is slower, it can cause debris to remain, resulting in repeated friction between the debris and the bottom surface of the first cleaning component 20, which can damage the first cleaning component 20 and slow down the cleaning speed and reduce the effect. By limiting the depth of the second channel 110 to be greater than or equal to the depth of the first channel 108, when the first cleaning component 20 is located on the second channel 110, the first scraper 14 and the first cleaning component 20 are in contact, but the water flow and the first cleaning component 20 are not in contact, thus avoiding secondary contamination of the first cleaning component 20.

[0191] The depth of the first channel 108 refers to the vertical distance from a point on the first scraper 14 to the bottom surface of the first channel 108. The depth of the second channel 110 refers to the vertical distance from a point on the first scraper 14 to the bottom surface of the second channel 110.

[0192] Optionally, the first channel 108 may include multiple first sub-channels with different depths and connected end to end, and the second channel 110 may include multiple second sub-channels with different depths and connected end to end. The depth of the second channel 110 may be the average depth of the second sub-channels, and the depth of the first channel 108 may be the average depth of the first sub-channels.

[0193] Similarly, the aforementioned beneficial effects also apply to the third cleaning tank 34 and the third water supply channel 68.

[0194] Please see Figure 11 In some embodiments, along the direction from the first inlet hole 26 to the outlet hole 28, the depth of the first channel 108 gradually increases, and the depth of the second channel 110 gradually increases.

[0195] In this way, along the water inlet to water outlet direction, the first cleaning component 20 is less likely to come into contact with the sewage in the channel.

[0196] Specifically, in one embodiment, along the direction from the first inlet hole 26 to the outlet hole 28, the depth of the end of the first channel 108 away from the first inlet hole 26 is greater than the depth of the end of the first channel 108 near the first inlet hole 26, and the depth of the first channel 108 gradually increases from the end near the first inlet hole 26 to the end away from the first inlet hole 26. In one embodiment, along the direction from the first inlet hole 26 to the outlet hole 28, the depth of the end of the second channel 110 near the outlet hole 28 is greater than the depth of the end of the second channel 110 away from the outlet hole 28, and the depth of the second channel 110 gradually increases from the end away from the outlet hole 28 to the end near the outlet hole 28, thereby making it less likely for the first cleaning component 20 to come into contact with the sewage in the channel.

[0197] Please see Figure 11 In some embodiments, the first channel 108 includes a first end 116 and a second end 118, and the second channel 110 includes a third end 120 and a fourth end 122. The first end 116 is connected to the second scraper 16, the second end 118 is connected to the third end 120, and the fourth end 122 is connected to the water outlet 28. The depth H1 of the first end 116 is in the range of [1,5] mm, the depth H2 of the second end 118 and the third end 120 is in the range of [2,8] mm, and the depth H3 of the fourth end 122 is in the range of [5,15] mm, and H1 <= H2 <= H3.

[0198] In this way, by determining the depth range of each end of the first channel 108 and the second channel 110, it can be further ensured that the first cleaning component 20 does not easily come into contact with the sewage in the channel.

[0199] Specifically, in one embodiment, the second scraper 16 is connected to the first water inlet 26, the first end 116 is connected to the second scraper 16, the second end 118 is connected to the third end 120, and the fourth end 122 is connected to the water outlet 28, so that water can be discharged into the water outlet 28. Furthermore, by setting the depth H1 of the first end 116 to the range of [1,5] mm, the depth H2 of the second end 118 and the third end 120 to the range of [2,8] mm, and the depth H3 of the fourth end 122 to the range of [5,15] mm, H1 <= H2 <= H3, thereby further ensuring that the first cleaning component 20 is not easily exposed to sewage in the channel.

[0200] The depth H1 of the first end 116 can be 1mm, 2mm, 3mm, 4mm, 5mm or other values ​​between 1mm and 5mm.

[0201] The depth H2 of the second end 118 and the third end 120 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm or other values ​​between 2mm and 8mm.

[0202] The depth H3 of the fourth end 122 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm or other values ​​between 5mm and 15mm.

[0203] Combination Figure 11 The first cleaning component 20, located at depth H1 from the first end 116 to depth H2 from the second end 118, needs to ensure that it can contact the water in the second water delivery channel, but it cannot completely block the second water delivery channel. The first cleaning component 20, located at depth H3 from the fourth end 122, needs to ensure that it does not contact the sewage in the second water delivery channel. The values ​​of H1, H2, and H3 are related to the height L1 of the first scraper, the vertical squeezing amount y between the first cleaning component 20 and the bottom surface 101 of the first cleaning tank 10, and the water flow height M in the second water delivery channel.

[0204] The clearance L0 between the first cleaning member 20 and the top of the second water supply channel is L0 = H1 - L1 - y; for H1 = L1 + y + L0, to ensure that the first cleaning member 20 can be wetted by water at H1 and the second water supply channel is not blocked, it is necessary to satisfy 0 < L0 < M, that is, L1 + y < H1 < M + L1 + y; similarly for H2, it is necessary to satisfy L1 + y < H2 < M + L1 + y; for H3, it is necessary to ensure that the first cleaning member 20 does not contact the sewage in the second water supply channel, that is, L0 > M, that is, H3 > L1 + y + M, and it is required that H1 < H2 < H3. When L1 = 1, y = 2, M = 3 (unit: millimeter), 3 < H1 < 6, 3 < H2 < 6; H3 > 6. According to different parameters of L1, y, and M, the heights of H1, H2, and H3 can be adjusted.

[0205] In some embodiments, along the direction from the first water inlet hole 26 to the water outlet hole 28, the inclination angle of the bottom surface of the first section of the channel 108 relative to the horizontal plane is smaller than the inclination angle of the bottom surface of the second section of the channel 110 relative to the horizontal plane.

[0206] In this way, the second section of the channel 110 is more inclined, which is beneficial for the sewage to flow faster and wash away the dirt.

[0207] Specifically, in combination with Figure 12 , the inclination angle a of the bottom surface of the first section of the channel 108 relative to the horizontal plane is smaller than the inclination angle b of the bottom surface of the second section of the channel 110 relative to the horizontal plane, a < b, which further makes the second section of the channel 110 more inclined, beneficial for the sewage to flow faster and wash away the dirt.

[0208] Optionally, a and b can be acute angles. Optionally, a can be an acute angle and b can be a right angle.

[0209] A cleaning device according to an embodiment of the present invention includes a base station, and the base station includes the cleaning tank structure 100 according to any one of the above embodiments.

[0210] In the above cleaning device, when the two cleaning members are placed in the corresponding cleaning tanks and on the squeegee, the contact area can directly contact the cleaning members when they are rotating and non-rotating. On the one hand, when cleaning the cleaning members, the cleaning members can rotate, so that the first squeegee 14 and the second squeegee 16 can effectively clean the first cleaning member 20 and the second cleaning member 24 respectively; on the other hand, the rotating first cleaning member 20 can clean the first contact area 18 and the rotating second cleaning member 24 can clean the second contact area 22, thereby avoiding or reducing the debris remaining on the bottom surface of the cleaning tank, and further avoiding or reducing the probability of the cleaning tank structure 100 emitting an odor.

[0211] Optionally, in one embodiment, the cleaning equipment may include a base station. In another embodiment, the cleaning equipment may include a base station and a cleaning robot 200.

[0212] Specifically, the base station includes a housing, with an accommodating space provided near the bottom. A cleaning tank structure 100 can be installed within the accommodating space, and the opening of the accommodating space can connect to the external environment. The base station also includes a climbing plate, which can be connected to the edge of the accommodating space near the bottom of the base station. A cleaning robot 200 can use the climbing plate to deliver cleaning components into the cleaning tank. It is understood that the cleaning tank structure can be installed not only in base stations but also on other equipment for cleaning components of other equipment.

[0213] The cleaning robot 200 includes a dual-rotor cleaning robot 200 (with two first cleaning components) and a single-rotor cleaning robot 200 (with a single first cleaning component), wherein the rotation axis of the cleaning component is based on a distance perpendicular to the body of the cleaning robot 200. A washing tank structure can be used in conjunction with the dual-rotor cleaning robot 200. After cleaning, the cleaning robot 200 can return to the base station, where the cleaning components can be placed in the washing tank for further cleaning. Simultaneously, the base station can also perform operations such as charging and dust collection on the cleaning robot 200. After the mop of the cleaning robot 200 has finished cleaning or after charging, the cleaning robot 200 can leave the base station to continue cleaning work, or remain at the base station until it receives the next cleaning instruction.

[0214] Optionally, the base station and the cleaning tank structure can be integrated, eliminating the need to disassemble the cleaning tank structure for cleaning. Alternatively, the cleaning tank structure can be detachably installed on the base station, allowing the user to remove it for cleaning.
