Figure 7 shown).

[0083] In the above-mentioned cleaning tank structure 100, at least a portion of the first baffle 12 can be movably connected to the bottom plate 14. At least a portion of the first baffle 12 in the second position opens the inlet and outlet 18 of the cleaning tank 16, thereby facilitating the cleaning robot to enter and exit the cleaning tank 16 through the inlet and outlet 18. At least a portion of the first baffle 12 in the first position closes the inlet and outlet 18 of the cleaning tank 16, facilitating the cleaning robot to clean the mop 200 and other operations.

[0084] Specifically, the first baffle 12 can switch positions according to different needs of the cleaning robot. According to different needs, the first baffle 12 is switched to achieve a cleaning effect. For example, when the cleaning robot returns to the station, at least a portion of the first baffle 12 is switched to the second position. When the cleaning robot returns to the station and positions itself, at least a portion of the first baffle 12 is switched to the first position, which can play a water blocking role and prevent the water spilled by the mop 200 during self-cleaning from overflowing. During the drying or air-drying stage of the mop 200, at least a portion of the first baffle 12 is located in the first position, which reduces the heat dissipation or wind loss area of ​​the mop 200 during drying or air-drying, and improves the drying or air-drying efficiency of the mop 200; when the cleaning robot leaves the station, at least a portion of the first baffle 12 is switched to the second position to facilitate the cleaning robot to leave the station.

[0085] Alternatively, the entire first stopper bar 12 may be movable to open and close the access port 18 .

[0086] Optionally, a portion of the first stop bar 12 may be stationary, and another portion may be movable to open and close the inlet and outlet 18. Figure 1 and Figure 3 The first stop bar 12 includes a first portion 20 and a second portion 22. The first portion 20 is fixedly connected to the bottom plate 14, and the second portion 22 is movably connected to the bottom plate 14. The second portion 22 can move between a first position and a second position. In the first position, the second portion 22 closes the inlet and outlet 18. In the second position, the second portion 22 opens the inlet and outlet 18. In the following embodiments, the movement of the second portion 22 is used to illustrate the implementation of the utility model.

[0087] The surface of the bottom plate 14 facing the cleaning tank 16 can be formed as the bottom surface of the cleaning tank 16, and the side of the first baffle 12 facing the cleaning tank 16 can be formed as the side wall of the cleaning tank 16. The cleaning tank structure 100 also includes a water inlet hole 24 and a second baffle 26. The first baffle 12, the second baffle 26 and the bottom plate 14 together surround the cleaning tank 16, and the water inlet hole 24 is connected to the cleaning tank 16. The first baffle 12 and the second baffle 26 are respectively connected to the two opposite edges of the water inlet hole 24. Compared with the first baffle 12, the second baffle 26 is far away from the inlet and outlet 18. The water inlet hole 24 can allow clean water to flow into the cleaning tank 16 to clean the mop 200 of the cleaning robot.

[0088] The cleaning robot comprises a body, and a mop 200 can be installed at the bottom of the body. The mop 200 can be disc-shaped. When the mop 200 of this embodiment rotates, its rotation axis is substantially perpendicular to the bottom of the body.

[0089] A scraper bar 28 is also provided in the cleaning tank 16, and the bottom surface 101 of the cleaning tank 16 includes a contact area 82. When the mop 200 is placed on the scraper bar 28, the contact area 82 can directly contact the mop 200 when it is rotating or not rotating. When the mop 200 is being cleaned, the cleaning robot can drive the mop 200 to rotate so that the mop 200 and the scraper bar 28 can produce relative motion. On the one hand, the scraper bar 28 can scrape off the dirt on the mop 200 to clean the mop 200. On the other hand, the rotating mop 200 can clean the contact area 82 of the bottom surface 101 of the cleaning tank 16 in a direct contact manner, avoiding the problem of residual dirt in the cleaning tank 16 causing the cleaning tank 16 to stink. Optionally, the scraper bar 28 can be fixedly connected to the bottom surface 101 of the cleaning tank 16, or can be detachably connected to the bottom surface 101 of the cleaning tank 16, and the utility model does not make specific restrictions on this.

[0090] Optionally, a single scraper bar 28 may be provided in the cleaning tank 16. Optionally, a plurality of scraper bars 28 may be provided in the cleaning tank 16. In the illustrated embodiment, two scraper bars 28 are provided in the cleaning tank 16, and the utility model does not specifically limit the number and position of the scraper bars 28.

[0091] Please combine Figure 1 and Figure 7 The cleaning tank structure 100 includes a water outlet 30, and the two scraping strips 28 and the bottom surface 101 of the cleaning tank 16 form a water supply channel 32, and the water supply channel 32 connects the water inlet 24 and the water outlet 30. Therefore, the water inlet 24 can supply clean water through the water supply channel 32, and at the same time, the sewage after cleaning can be discharged from the water outlet 30 through the water supply channel 32. The mop 200 can be wetted and scraped in the water supply channel 32 near the water inlet 24. A part of the sewage formed by cleaning the mop 200 can flow to the water outlet 30 through the water supply channel 32, and the other part can flow into the cleaning tank 16 between the scraping strip 28 and the baffle bar, and flow to the water outlet 30 through the cleaning tank 16.

[0092] Optionally, the cleaning tank structure 100 includes a third baffle 34 , the third baffle 34 connects the first baffle 12 and the second baffle 26 , and the third baffle 34 is surrounded by a water inlet 24 .

[0093] Specifically, in Figure 1 In the embodiment, the third baffle 34 may be similar to a U-shape. One end of the third baffle 34 may be connected to the first portion 20, and the other end may be connected to the second baffle 26. The third baffle 34 is surrounded by a water inlet hole 24, so that clean water can flow from the water inlet hole 24 into the cleaning tank 16 and the water supply channel 32.

[0094] Optionally, the end surface of the second baffle 26 away from the bottom surface 101 of the cleaning tank 16 (i.e., the top surface of the second baffle 26) and the end surface of the third baffle 34 away from the bottom surface 101 of the cleaning tank 16 (i.e., the top surface of the third baffle 34) may be located in the same horizontal plane, and the end surface of the first baffle 12 away from the bottom surface 101 of the cleaning tank 16 (i.e., the top surface of the first baffle 12) may be located below the above-mentioned horizontal plane.

[0095] The cleaning robot can enter and exit the cleaning tank 16 through the inlet and outlet 18, so that the mop 200 is located inside or outside the cleaning tank 16. When the second portion 22 is located at the first position, the second portion 22 closes the inlet and outlet 18, and the cleaning robot cannot enter and exit the cleaning tank 16 through the inlet and outlet 18. When the second portion 22 is located at the second position, the second portion 22 opens the inlet and outlet 18, and the cleaning robot can enter and exit the cleaning tank 16 through the inlet and outlet 18, thereby facilitating the cleaning robot to enter and exit the cleaning tank 16, and not easily causing damage to the mop 200 and the first stop bar 12.

[0096] In some embodiments, when the mop 200 of the cleaning robot is located in the cleaning tank 16, at least a portion of the first stop bar 12 is located in the first position to close the inlet and outlet 18, so that the mop 200 can perform a self-cleaning operation;

[0097] When the cleaning robot leaves or enters the cleaning tank 16 , at least a portion of the first blocking bar 12 is located at the second position to open the access 18 , so that the cleaning robot can leave or enter the cleaning tank 16 .

[0098] This makes it easier for the cleaning robot to operate the mop 200 .

[0099] Optionally, combine Fig.29 The cleaning tank structure 100 can be installed in the housing 302 of the base station 300. Specifically, the housing 302 can be provided with a receiving chamber 304 near the bottom. The cleaning tank structure 100 can be installed in the receiving chamber 304, and the opening of the receiving chamber 304 can be connected to the external environment.

The cleaning robot can enter and exit the base station 300 through the climbing plate 306. It can be understood that the cleaning tank structure 100 can be set not only in the base station 300, but also in other equipment for cleaning components of other equipment.

[0100] In the initial state, the second part 22 is in the first position to close the entrance and exit 18, and the mop 200 is located in the cleaning tank 16. The cleaning robot can drive the mop 200 to rotate to clean the mop 200. After the cleaning is completed, the cleaning robot leaves the station, and the second part 22 switches to the second position to open the entrance and exit 18, and the cleaning robot leaves the station to perform the cleaning task. After the cleaning robot completes the cleaning task, it returns to the base station 300 through the entrance and exit 18. After confirming that the cleaning robot has returned to the base station 300, the second part 22 switches to the first position to close the entrance and exit 18, and the cleaning robot can drive the mop 200 to rotate to clean the mop 200, while avoiding or reducing the water in the cleaning tank 16 from splashing out of the cleaning tank 16.

[0101] In some embodiments, at least a portion of the first stopper bar 12 is liftably connected to the bottom plate 14 , and at least a portion of the first stopper bar 12 moves between the first position and the second position through a lifting motion.

[0102] In this way, the stop bar can be moved by means of a lifting movement.

[0103] Specifically, in the illustrated embodiment, the second portion 22 can perform a lifting motion to move between the first position and the second position.

[0104] Optionally, when the second part 22 is located at the first position, the top of the second part 22 is higher than the top of the climbing plate 306 , and when the second part 22 is located at the second position, the top of the second part 22 is lower than the top of the climbing plate 306 .

[0105] In certain embodiments, see Figure 6 and Fig.10 The first stop bar 12 includes a first portion 20 and a second portion 22 connected to each other. Compared with the bottom surface 101 of the cleaning tank 16, the height T2 of the second portion 22 is less than the height T1 of the first portion 20. The first portion 20 is fixedly connected to the bottom plate 14, and the second portion 22 is movably connected to the bottom plate 14. The cleaning tank structure 100 includes a first driving member 36, which is connected to the second portion 22 and is configured to drive the second portion 22 to rise and fall so that the second portion 22 is in the first position (such as Figure 6 as shown) and a second position (as Figures 7 to 9 )

[0106] Thus, the second part 22 can be automatically driven to rise and fall by the first driving member 36 .

[0107] Optionally, the first driving member 36 may include a linear motor, and the linear motor may include a moving rod, and the moving rod is connected to the second part 22 . The linear motor may drive the moving rod to move up and down, thereby driving the second part 22 to move up and down.

[0108] Optionally, the first driving member 36 may include a cylinder connected to the second part 22 , and the cylinder may drive the second part 22 to move up and down when working.

[0109] Optionally, the first driving member 36 may include a rotating motor, which is connected to the second part 22 through a transmission assembly. The transmission assembly converts the rotational motion of the output shaft of the rotating motor into translational motion, thereby driving the second part 22 to rise and fall. The transmission assembly includes but is not limited to belts, screws, gears, etc.

[0110] Optionally, in one embodiment, the second part 22 can also be manually controlled to be raised or lowered. For example, the user can use a tool to clamp the second part 22 for raising or lowering, and when the user releases the second part 22, the second part 22 can remain in the current position. For example, the second part 22 and the bottom plate 14 can be tightly matched to keep the second part 22 in the current position.

[0111] Optionally, the height T2 of the second portion 22 may refer to the vertical distance between the top of the second portion 22 and the bottom surface 101 of the cleaning tank 16 , and the height T1 of the first portion 20 may refer to the vertical distance between the top of the first portion 20 and the bottom surface 101 of the cleaning tank 16 .

[0112] In some embodiments, at least a portion of the first stop bar 12 is slidably connected to the bottom plate 14 , and at least a portion of the first stop bar 12 moves between the first position and the second position through a horizontal sliding motion.

[0113] Thus, at least a portion of the first stopper bar 12 can open and close the inlet and outlet 18 in a horizontally sliding manner.

[0114] Specifically, in Fig.12 In the embodiment shown in the figure, the horizontal direction can be the left-right direction, that is, at least a portion of the first stop bar 12 can slide in the left-right direction to open and close the inlet and outlet 18. Figure 4 In the embodiment, the first stop bar 12 closes the inlet and outlet 18, and at least a portion of the first stop bar 12 can slide to the left to a second position to open the inlet and outlet 18. Figures 11 to 13 When the access port 18 is opened, at least a portion of the first stop bar 12 can slide rightward to the first position to close the access port 18, as shown in FIG. Figure 4 shown.

[0115] In some embodiments, see Figure 6 and Figures 11 to 13The first baffle 12 includes a first portion 20 and a second portion 22 connected to each other. Compared with the bottom surface 101 of the cleaning tank 16, the height T2 of the second portion 22 is less than the height T1 of the first portion 20. The first portion 20 is fixedly connected to the bottom plate 14, and the second portion 22 is movably connected to the bottom plate 14. The cleaning tank structure 100 includes a telescopic mechanism connected to the second portion 22, and the telescopic mechanism is configured to drive the second portion 22 to slide to move between the first position and the second position when telescoping.

[0116] Thus, the second part 22 can be automatically driven to slide by the telescopic mechanism.

[0117] Specifically, the first stop bar 12 or the second portion 22 is retractable. The telescopic mechanism itself can be extended and shortened, thereby driving the second portion 22 to slide. Fig.12 In the embodiment, for the left cleaning tank 16, when the telescopic mechanism is extended, the second part 22 can be driven to slide rightward to the first position to close the inlet and outlet 18. When the telescopic mechanism is shortened, the second part 22 can be driven to slide leftward to the second position to open the inlet and outlet 18.

[0118] In certain embodiments, see Fig.14 and Fig.15 The telescopic mechanism includes a connecting rod assembly 38, one end of which is rotatably connected to the second part 22, and the connecting rod assembly 38 is configured to drive the second part 22 to slide during telescoping.

[0119] Thus, the sliding movement of the second portion 22 can be achieved by extending and retracting the connecting rod assembly 38 .

[0120] Specifically, when the connecting rod assembly 38 is extended or shortened, one end of the connecting rod assembly 38 connected to the second portion 22 can drive the second portion 22 to slide back and forth, and thus can move between the first position and the second position.

[0121] Optionally, the other end of the connecting rod assembly 38 can be rotatably connected to the first portion 20 , or can be rotatably connected to other structural components of the cleaning tank structure 100 .

[0122] In certain embodiments, see Fig.16 and Fig.17 The telescopic mechanism includes a second driving member 40, a limiting member 42, a transmission member 44 and a connecting rod 46. The output shaft of the second driving member 40 is connected to the transmission member 44. One end of the connecting rod 46 is rotatably connected to the transmission member 44, and the other end is rotatably connected to the connecting rod assembly 38. The limiting member 42 is provided with a limiting groove 48, and the transmission member 44 is provided with a limiting block 50. The limiting block 50 is located in the limiting groove 48. The second driving member 40 is configured to drive the transmission member 44 to rotate to drive the limiting block 50 to move in the limiting groove 48, so that the connecting rod 46 drives the second part 22 to slide through the connecting rod assembly 38.

[0123] Thus, the second portion 22 can be driven to slide by the second driving member 40 .

[0124] Specifically, the second portion 22 is in the first position of closing the inlet and outlet 18, and the length of the connecting rod assembly 38 is relatively long. Fig.14 The second portion 22 is in the second position of opening the inlet and outlet 18, and the length of the connecting rod assembly 38 is shorter, such as Fig.15 shown.

[0125] Optionally, the second driving member 40 may include a rotary motor. Fig.16 Rotate 180 degrees clockwise R1 or counterclockwise R2 to Fig.17 In the state shown in FIG. 4 , the connecting rod 46 moves from right to left, and one end of the connecting rod 46 drives the connecting rod assembly 38 to shorten, thereby causing the second part 22 to slide from right to left in the first position to the second position.

[0126] Rotating motor from Fig.17 Rotate 180 degrees clockwise R1 or counterclockwise R2 to Fig.16 In the state shown in FIG. 1 , the connecting rod 46 moves from left to right, and one end of the connecting rod 46 drives the connecting rod assembly 38 to extend, thereby causing the second part 22 to slide from left to right in the second position to the first position.

[0127] The cooperation between the limiting groove 48 and the limiting block 50 can limit the moving trajectory of the transmission member 44, so that the movement of the connecting rod 46 and the connecting rod assembly 38 is more stable, thereby improving the sliding mobility of the second part 22.

[0128] Optionally, the connecting rod assembly 38 includes a plurality of connecting rods 52, the head ends and tail ends of the plurality of connecting rods 52 are rotatably connected to each other, and the connecting rod assembly 38 can be extended or shortened by changing the angle between the two connecting rods 52. The head end of the first connecting rod 52 can be rotatably connected to the first part 20 or other structural members of the cleaning tank structure 100, and the tail end of the last connecting rod 52 can be rotatably connected to the second part 22. The utility model does not specifically limit the number of connecting rods 52.

[0129] In some embodiments, see Fig.18 The cleaning tank structure 100 includes a seal 54 , which seals and connects at least a portion of the first baffle 12 and a side edge of the bottom plate 14 .

[0130] Thereby, the sealing property of the cleaning tank 16 can be improved.

[0131] Specifically, in one embodiment, the second portion 22 is a movable portion of the first stop bar 12. The seal 54 seals and connects the second portion 22 and the side of the bottom plate 14, so that the water in the cleaning tank 16 will not leak from the gap between the second portion 22 and the bottom plate 14 to affect the use of the cleaning tank structure 100.

[0132] Optionally, a receiving groove 56 is provided on the side of the bottom plate 14, and the seal 54 can be partially received in the receiving groove 56, thereby the seal 54 can be fixedly installed on the side of the bottom plate 14 to prevent the seal 54 from being displaced during the movement of the second part 22 and affecting the sealing effect.

[0133] Optionally, the sealing member 54 may be made of silicone.

[0134] In some embodiments, the cleaning tank structure 100 includes a second baffle 26. The first baffle 12, the second baffle 26 and the bottom plate 14 together form a cleaning tank 16. The cleaning tank structure 100 is provided with a water inlet 24, which is connected to the cleaning tank 16. The first baffle 12 and the second baffle 26 are respectively connected to two opposite edges of the water inlet 24. Compared with the first baffle 12, the second baffle 26 is far away from the inlet and outlet 18.

[0135] The connection between the second baffle 26 and the edge of the water inlet hole 24 is closer to the center of the cleaning tank 16 than the connection between the first baffle 12 and the edge of the water inlet hole 24;

[0136] Along the rotation direction of the mop 200 of the cleaning robot in the cleaning tank 16 , the connection between the second baffle 26 and the edge of the water inlet hole 24 is located behind the connection between the first baffle 12 and the edge of the water inlet hole 24 .

[0137] Thereby, the cleaning effect of the mop 200 can be improved.

[0138] Specifically, the connection between the second baffle 26 and the edge of the water inlet hole 24 is hereinafter referred to as the second connection 57 , and the connection between the first baffle 12 and the edge of the water inlet hole 24 is hereinafter referred to as the first connection 58 .

[0139] Please combine Figure 2 , the mop 200 in the left cleaning tank 16 rotates in the clockwise direction R1 during cleaning. In the clockwise direction R1, the second connection 57 is located behind the first connection 58. When the mop 200 on the left is cleaned, the mop 200 rotates in the clockwise direction R1, so that when the mop 200 moves from the cleaning tank 16 part surrounded by the first baffle 12 to the cleaning tank 16 part surrounded by the second baffle 26, the fluff of the mop 200 can hit the second connection 57 closer to the center of the cleaning tank 16, so that the dirty water and debris on the mop 200 can be hit and fall into the cleaning tank 16.

[0140] The mop 200 in the right cleaning tank 16 rotates in the counterclockwise direction R2 during cleaning. In the counterclockwise direction R2, the second connection 57 is located behind the first connection 58. When the mop 200 on the right is cleaned, the mop 200 rotates in the counterclockwise direction R2, so that when the mop 200 moves from the cleaning tank 16 portion surrounded by the first baffle 12 to the cleaning tank 16 portion surrounded by the second baffle 26, the fluff of the mop 200 can hit the second connection 57 closer to the center of the cleaning tank 16, so that the dirty water and debris on the mop 200 can be hit and fall into the cleaning tank 16.

[0141] In summary, the cleaning effects of the two mops 200 can be improved.

[0142] exist Figure 3 In the embodiment, the first baffle 12 is a front baffle and the second baffle 26 is a rear baffle. Optionally, the first baffle 12 and the second baffle 26 can both be soft baffles. Optionally, the first baffle 12 can be a soft baffle and the second baffle 26 can be a hard baffle. Optionally, the first baffle 12 and the second baffle 26 can both be hard baffles. The soft baffle can be made of soft rubber (TPU, silicone, etc.). Optionally, the hard baffle can be made of hard rubber (ABS, PC, etc.). The utility model does not specifically limit the material of the baffle.

[0143] Optionally, the height of the second baffle 26 relative to the bottom surface 101 of the cleaning tank 16 is greater than the height of the first baffle 12. The second baffle 26 is away from the station entrance 52. After the cleaning robot returns to the station, the mop 200 can be placed in the cleaning tank 16. The higher second baffle 26 relative to the bottom surface 101 of the cleaning tank 16 can prevent or reduce the sewage in the cleaning tank 16 from being spilled outside the cleaning tank 16, thereby avoiding additional cleaning burden on the user.

[0144] exist Figure 1 In the embodiment, the first stop bar 12 and the second stop bar 26 are both arc-shaped to form a substantially circular cleaning groove 16, and the circular cleaning groove 16 can be adapted to be used with the rotating mop 200. It can be understood that the present invention does not specifically limit the shapes of the cleaning groove 16 and the mop 200.

[0145] Optionally, the diameter of the circle where the first baffle 12 is located is greater than the diameter of the circle where the second baffle 26 is located, and the width E1 of the first baffle 12 along the horizontal direction is greater than the width E2 of the second baffle 26 along the horizontal direction.

[0146] This helps to overcome the offset error when the cleaning robot returns to the station.

[0147] Specifically, in Figure 2When the cleaning robot returns to the station, it needs to enter the cleaning tank 16 through the entrance and exit. The first baffle 12 has a larger horizontal width E1, which is beneficial for the cleaning tank structure 100 to overcome the offset error when the cleaning robot returns to the station, making it easier for the cleaning robot to enter and exit the station.

[0148] In some embodiments, please combine Figure 1 , Figure 7 and Figure 20 to Figure 21 The cleaning tank structure 100 includes a water outlet 30 and a filter 60 . The water outlet 30 is connected to the cleaning tank 16 , and the filter 60 is accommodated in the water outlet 30 .

[0149] Thus, the filter element 60 can filter sewage to avoid pipe blockage.

[0150] Specifically, in Figure 7 In the embodiment, the water outlet 30 is provided on the bottom surface 101 of the cleaning tank 16. Fig. 20 A filter chamber 62 is provided in the filter element 60, and filter holes 64 are provided at the bottom and / or side walls of the filter chamber 62. Sewage can be filtered through the filter holes 64 and then flow out of the cleaning tank 16. Impurities in the sewage can remain in the filter element 60, thereby avoiding pipe blockage and facilitating the cleaning of impurities.

[0151] In one embodiment, the sewage scraped by the mop 200 can flow into the filter chamber 62. At this time, the debris in the sewage can be blocked by the filter hole 64 and remain in the filter element 60. The filtered sewage can be discharged through the water outlet 30, thereby filtering the sewage and avoiding pipe blockage.

[0152] Optionally, the filter element 60 is detachably disposed in the water outlet 30, and the debris accumulated in the filter element 60 can be removed by removing the filter element 60 for regular cleaning. After cleaning, the filter element 60 is installed in the water outlet 30. The number and shape of the filter holes 64 are not specifically limited. The number of the filter holes 64 can be set to multiple, and the shape of the filter holes 64 can be set not only to a circle but also to other shapes. Optionally, a handle 66 is also provided on the filter element 60 to facilitate the user to disassemble and assemble the filter element 60.

[0153] In some embodiments, please combine Figure 1 , Figure 7 and Figures 19 to 21 The cleaning tank structure 100 includes a drain pipe 68, which is connected to the cleaning tank 16 through the water outlet hole 30. A recess 67 is provided at the bottom of the filter element 60, and the recess 67 is correspondingly connected to a connecting hole 69 formed on the wall of the water outlet hole 30 by the drain pipe 68.

[0154] Thus, the concave portion 67 at the bottom of the filter element 60 corresponds to the communicating hole 69 , and water can flow into the drain pipe 68 more easily.

[0155] Specifically, since the concave portion 67 is correspondingly connected to the communication hole 69, the communication hole 69 can be connected to the space surrounded by the concave portion 67, and the filter element 60 does not block or blocks the communication hole 69 less, the sewage flowing out of the filter element 60 is more likely to flow into the communication hole 69 and flow out of the cleaning tank structure 100 through the drain pipe 68, so that the sewage can be discharged from the cleaning tank 16 in time. The side wall of the concave portion 67 is provided with a filter hole 64. Corresponding to the concave portion 67, a convex hull 70 is formed in the filter cavity 62.

[0156] In certain embodiments, see Fig.19 The bottom of the cleaning tank structure 100 is provided with a receiving cavity 72, and the drain pipe 68 is located in the receiving cavity 72. Therefore, the drain pipe 68 is located in the receiving cavity 72, and the drain pipe 68 is shorter, which can reduce the cost of the cleaning tank structure 100.

[0157] Specifically, in one embodiment, the cleaning tank structure 100 can be manufactured by a mold. The drain pipe 68 is located in the accommodating cavity 72, and the drain pipe 68 does not extend out of the accommodating cavity 72. The drain pipe 68 is relatively short. On the one hand, the shorter drain pipe 68 can be pushed out of the mold by a shorter push rod, making it easier to open the mold of the cleaning tank structure 100. On the other hand, the shorter drain pipe 68 can also reduce the use of materials, so that the cost of the cleaning tank structure 100 is reduced. In summary, the cost of the cleaning tank structure 100 can be reduced.

[0158] Optionally, the drain pipe 68 has a water pipe interface 74 , which is located in the accommodating cavity 72 , and the pipeline can be inserted into the drain pipe 68 through the water pipe interface 74 to guide the water flow out of the cleaning tank structure 100 .

[0159] In certain embodiments, see Figure 1 , the cleaning tank structure 100 is provided with an air inlet 76, and the air inlet 76 is connected to the cleaning tank 16;

[0160] When the mop 200 of the cleaning robot is located in the cleaning tank 16, at least a portion of the first stop bar 12 is located in the first position to close the inlet and outlet 18, so that the mop 200 can be dried or air-dried by the air blown in from the air inlet 76;

[0161] When the cleaning robot leaves or enters the cleaning tank 16 , at least a portion of the first blocking bar 12 is located at the second position to open the access 18 , so that the cleaning robot can leave or enter the cleaning tank 16 .

[0162] Thus, the heat dissipation or wind loss area of ​​the mop 200 during drying or air-drying can be reduced, thereby improving the drying or air-drying efficiency of the mop 200.

[0163] Specifically, after the mop 200 is cleaned, it can be dried or air-dried. At this time, the mop 200 of the cleaning robot is located in the cleaning tank 16, and at least a portion of the first baffle 12 is located in the first position to close the inlet and outlet 18. The base station 300 can blow hot air or normal temperature air into the cleaning tank 16 through the air inlet 76 to dry or air-dry the mop 200 in the cleaning tank 16. Since at least a portion of the first baffle 12 (such as the second portion 22) closes the inlet and outlet 18, it is not easy for air to leak from the cleaning tank 16, reducing the heat dissipation or wind loss area of ​​the mop 200 when drying or air-drying, and improving the drying or air-drying efficiency of the mop 200.

[0164] When the cleaning robot leaves the station, the second part 22 switches from the first position to the second position (eg, the second part 22 descends), and the inlet and outlet 18 is opened, so that the cleaning robot can leave the station conveniently.

[0165] When the cleaning robot enters the station, the second part 22 switches from the first position to the second position (eg, the second part 22 descends), and the inlet and outlet 18 is opened, so that the cleaning robot can enter the station conveniently.

[0166] In certain embodiments, the cleaning tank structure 100 includes a base 78 with the cleaning tank 16 disposed therein.

[0167] Thus, the base 78 can provide an installation structure for the cleaning tank structure 100 , facilitating the installation of the cleaning tank structure 100 .

[0168] Specifically, in Figure 4 In the illustrated embodiment, the base 78 may be similar to a long plate. The cleaning tank structure 100 may be mounted on the base station 300 via the base 78. Two cleaning tanks 16 are disposed on the base 78. The side walls of the two cleaning tanks 16 may be connected, and the two cleaning tanks 16 are interconnected, so that the two cleaning tanks 16 may share a water outlet 30. Each cleaning tank 16 may also be independently disposed. Optionally, the base 78 may be connected to the cleaning tank 16 and the scraper bar 28 as an integral structure.

[0169] In some embodiments, please combine Figure 22 to Figure 24 , the bottom surface 101 of the cleaning tank 16 includes a contact area 82;

[0170] The cleaning tank structure 100 is configured as follows:

[0171] When the mop 200 is placed on the scraper bar 28, the contact area 82 is in direct contact with the mop 200 when it is rotating or not rotating.

[0172] Therefore, when the mop 200 is placed on the scraper bar 28, the contact area 82 can directly contact the mop 200 when it is rotating or not, and then in the process of cleaning the mop 200, the rotating mop 200 can clean the contact area 82, which can avoid or reduce the debris remaining on the bottom surface 101 of the cleaning tank 16, and thus avoid the cleaning tank structure 100 from stinking or reduce the chance of the cleaning tank structure 100 stinking.

[0173] In one embodiment, when the mop 200 of the cleaning robot is cleaning, the cleaning robot can enter the base station 300, the mop 200 can be placed on the scraper bar 28, and the contact area 82 can directly contact the mop 200 when it is not rotating.

[0174] While the scraper bar 28 is scraping the mop 200, the rotating mop 200 can also directly contact the contact area 82. In the process of cleaning the mop 200, the rotating mop 200 can also clean the contact area 82, which can avoid or reduce the debris remaining on the bottom surface 101 of the cleaning tank 16, thereby avoiding the cleaning tank structure 100 from stinking or reducing the chance of the cleaning tank structure 100 stinking.

[0175] Optionally, in one embodiment, the entire bottom surface 101 of the cleaning tank 16 may be the contact area 82, that is, the entire bottom surface 101 of the cleaning tank 16 is in direct contact with the rotating and non-rotating mop 200. Fig. 22 In the embodiment, the mop 200 may be provided with an opening near the center of the mop 200. Optionally, in other embodiments, the mop 200 may not be provided with an opening near the center of the mop 200.

[0176] The cleaning tank structure 100 shown in the figure is provided with two cleaning tanks 16, which can be adapted to a cleaning robot with a double turntable cleaning member. A mop 200 can be provided at the bottom of each turntable cleaning member. The rotation of the turntable cleaning member can drive the mop 200 to rotate, and the rotation axis of the mop 200 is substantially perpendicular to the bottom of the fuselage. When the two mops 200 are cleaning, the rotation directions of the two mops 200 can be the same or opposite, and the utility model does not specifically limit this. During the cleaning process of the cleaning robot, the rotation directions of the two mops 200 can be the same or opposite. It can be understood that in other embodiments, the cleaning tank structure 100 can also be provided with a single cleaning tank 16, which can be adapted to a cleaning robot with a single turntable cleaning member.

[0177] In certain embodiments, see Fig.24 The bottom surface 101 of the cleaning tank 16 includes a non-contact area 84. When the mop 200 is placed on the scraper bar 28, the vertical distance between the non-contact area 84 and the plane P where the mop 200 is located is in the range of (0,3] mm.

[0178] In this way, during the process of cleaning the mop 200, when the mop 200 is placed on the scraper bar 28, the mop 200 can drive the water flow to the non-contact area 84 during rotation to clean the non-contact area 84, while increasing the non-contact area 84, and can also reduce the friction between the mop 200 and the bottom surface 101 of the cleaning tank 16, reduce energy consumption, and can be adapted to a low-power motor.

[0179] Specifically, in one embodiment, when the mop 200 is placed on the scraper bar 28, the bottom surface 101 of the cleaning tank 16 further includes a non-contact area 84. While the scraper bar 28 is scraping the mop 200, the vertical distance W between the non-contact area 84 of the bottom surface 101 of the cleaning tank 16 and the plane P where the mop 200 is located is in the range of (0,3] mm. During the process of cleaning the mop, the mop can drive the water flow to the non-contact area 84 when rotating to clean the non-contact area 84. Optionally, Fig.25 In the illustrated embodiment, the mop 200 includes fluff 202 and a chassis 204 , the fluff 202 is disposed at the bottom of the chassis 204 , and the vertical distance W between the non-contact area 84 and the plane P where the mop 200 is located can be the vertical distance between the non-contact area 84 and the bottom surface of the fluff 202 .

[0180] In some examples, the vertical distance W between the non-contact area 84 and the plane P where the mop 200 is located 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 84 and the plane P where the mop 200 is located can be specifically determined according to actual needs, and the present invention does not specifically limit this.

[0181] Optionally, both the contact area 82 and the non-contact area 84 are planes. In one embodiment, the contact area 82 may be an inclined surface, and the non-contact area 84 may also be an inclined surface, and the slope of the non-contact area 84 is greater than the slope of the contact area 82. In one embodiment, the slope of the non-contact area 84 may also be less than the slope of the contact area 82. In one embodiment, the contact area 82 may be a horizontal surface, and the non-contact area 84 may also be a horizontal surface. In one embodiment, the contact area 82 may be a horizontal surface, and the non-contact area 84 may be an inclined surface. In one embodiment, the contact area 82 may be an inclined surface, and the non-contact area 84 may be a horizontal surface. In one embodiment, the contact area 82 may be an inclined surface, and the non-contact area 84 may be an inclined surface, and the slope of the non-contact area 84 is equal to the slope of the contact area 82. The contact area 82 may be a curved surface or an arc surface, and the non-contact area 84 may also be a curved surface or an arc surface. Alternatively, the contact area 82 may be a plane and the non-contact area 84 may be a curved surface or an arc surface. Alternatively, the non-contact area 84 may be a plane and the contact area 82 may be a curved surface or an arc surface. In summary, when the mop 200 is placed on the scraper bar 28, the vertical distance W between the non-contact area 84 and the plane P where the mop 200 is located is less than or equal to 3 mm.

[0182] Please combine Fig.26 It can be seen from the effect diagram that when the vertical distance W between the non-contact area 84 and the plane P where the mop 200 is located is in the range of (0,3] mm, even in the area where the mop 200 is not in contact with the bottom surface 101 of the cleaning tank 16, the rotating mop 200 can have the desired cleaning effect on the non-contact area 84, reducing the probability of the cleaning tank structure 100 stinking.

[0183] Specifically, in Fig.26 In the figure, y represents the vertical extrusion amount between the mop 200 and the bottom surface 101 of the cleaning tank 16, in mm. When y<0, it means that the mop 200 is isolated from the bottom surface 101 of the cleaning tank 16. At this time, the absolute value of y represents the isolation amount (i.e., the vertical distance W). F represents the cleaning effect of the cleaning robot after one self-cleaning. In each test, 5g of yellow mud is sprinkled on the ground. After the cleaning robot returns to the station and undergoes a self-cleaning, the weight z (in g) of the increased dirt in the cleaning tank 16 is weighed, and F=1-z / 5×100%. After one self-cleaning, F>=90% of the cleaning effect meets the cleaning requirements.

[0184] from Fig.26It can be seen that when y>=-3 (i.e., the range of the vertical distance W is (0,3] mm), the cleaning effect F>=90%, which meets the cleaning requirements. When -3<=y<0, the mop 200 will drive the water in the cleaning tank 16 to flow when rotating, and the cleaning tank 16 is rinsed by the water flow, thereby achieving the effect of cleaning the cleaning tank 16. When y>0, there is extrusion between the mop 200 and the bottom surface 101 of the cleaning tank 16, and the friction between the mop 200 and the bottom surface 101 of the cleaning tank 16 makes the cleaning effect meet the requirements. Based on the fact that the mop 200 is composed of the chassis 204 and the fluff 202, the chassis 204 is a hard material that is difficult to squeeze, so the vertical extrusion amount between the mop 200 and the bottom surface 101 of the cleaning tank 16 cannot be obtained by the thickness of the mop 200. The test data is shown in Table 1 below. The smaller z is, the less yellow mud remains in the cleaning tank 16, and the better the cleaning effect of the cleaning tank 16.

[0185] Table 1

[0186] y z F -4 1.5 70％ -3 0.5 90％ 0 0 100％ 1.1 (1 / 6 of the total thickness of the mop) 0 100％ 2.2 (1 / 3 of the total thickness of the mop) 0 100％ 4.3 (accounting for 2 / 3 of the total thickness of the mop) 0 100％ 6.0 (100% of mop thickness) 0 100％

[0187] In some embodiments, the range of the amount of compression between the mop 200 and the bottom surface 101 of the cleaning tank 16 is [0, T) mm, where T is the thickness of the mop 200 .

[0188] In this way, the amount of squeezing between the mop 200 and the bottom surface 101 of the cleaning tank 16 meets the cleaning effect requirements.

[0189] Specifically, the thickness T of the mop 200 includes the length V2 of the fluff 202 and the thickness V3 of the chassis 204. The range of the amount of extrusion between the mop 200 and the bottom surface 101 of the cleaning tank 16 is [0, T) mm, where T is the thickness of the mop 200. The greater the amount of extrusion between the mop 200 and the bottom surface 101 of the cleaning tank 16, the greater the friction between the mop 200 and the bottom surface 101 of the cleaning tank 16, and the better the cleaning effect. It should be noted that when the amount of extrusion between the mop 200 and the bottom surface 101 of the cleaning tank 16 is close to the thickness T of the mop 200, the friction between the mop 200 and the bottom surface 101 of the cleaning tank 16 is relatively large. At this time, it is still within the range where the mop 200 can rotate (that is, the motor of the cleaning robot can still drive the mop 200 to rotate), which will not affect the cleaning of the mop 200.

[0190] In some examples, the amount of compression between the mop 200 and the bottom surface 101 of the cleaning tank 16 may be 0 mm, (1 / T) mm, (2 / T) mm, (3 / T) mm, (4 / T) mm, (5 / T) mm, or other values ​​within [0, T), which are not specifically limited in the present invention. The amount of compression between the mop 200 and the bottom surface 101 of the cleaning tank 16 is 0 mm, indicating that the contact surface between the fluff 202 and the bottom surface 101 of the cleaning tank 16 is not compressed.

[0191] In some embodiments, the cleaning tank structure 100 is configured such that when the mop 200 is placed in the cleaning tank 16 , a horizontal distance U between an edge of the mop 200 and a side wall of the cleaning tank 16 is in a range of (0, 8] mm.

[0192] In this way, the water carried by the mop 200 is thrown to the side wall of the cleaning tank 16 under the action of centrifugal force, so that the side wall of the cleaning tank 16 is cleaned.

[0193] Specifically, when the mop 200 is placed in the cleaning tank 16 and rotates on the scraper bar 28 for cleaning, the edge of the mop 200 can contact a portion of the side wall of the cleaning tank 16 (such as Fig.24 The horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0,8] mm. For example, the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 16 can be 8 mm, 7.8 mm, 7.5 mm, 6 mm, 5.5 mm, 5 mm or other values ​​less than 8 mm. The horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 16 can be specifically determined according to actual needs, and the utility model does not make specific limitations on this.

[0194] When the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0,8] mm, when the mop 200 rotates on the scraper 28 for cleaning, the water carried by the mop 200 is thrown to the side wall of the cleaning tank 16 under the action of centrifugal force, and the water can clean the side wall of the cleaning tank 16, thereby achieving the cleaning of the side wall of the cleaning tank 16. In addition, when the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0,8] mm, it is also beneficial for the cleaning robot to place the mop 200 in the cleaning tank 16, which is easy to position.

[0195] Please combine Fig. 27 It can be seen from the effect diagram that when the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0,8] mm, even when the edge of the mop 200 does not contact the side wall of the cleaning tank 16, the rotating mop 200 can still have the desired cleaning effect on the non-contacting side wall area of ​​the cleaning tank 16, thereby reducing the probability of the cleaning tank structure 100 stinking.

[0196] Specifically, in Fig. 27In the figure, x represents the horizontal extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 16 (if there is a baffle 22, it is the side of the baffle 22 facing the cleaning tank 16), and the unit is mm. When x<0, it means that the edge of the mop 200 is isolated from the side wall of the cleaning tank 16. The absolute value of x represents the isolation amount, that is, the horizontal distance U. F represents the cleaning effect of the cleaning robot after one self-cleaning. In each test, 5g of yellow mud is sprinkled on the ground. After the cleaning robot returns to the station and undergoes a self-cleaning, the weight z (in g) of the dirt added to the cleaning tank 16 is weighed, and F=1-z / 5×100%. After one self-cleaning, F>=90% of the cleaning effect meets the cleaning requirements.

[0197] In this test, the y value is fixed, such as setting y = 1mm. Fig. 27 It can be seen that when -8<=x<=10, the cleaning effect F>=90%, which meets the cleaning requirements. When x<-8, the side wall of the cleaning tank 16 is too far away from the edge of the mop 200. When the mop 200 rotates, it cannot clean the side wall of the cleaning tank 16 by relying on the water flow and the fluff 202. There is a blind area and the cleaning effect is not good. When x>10, the mop 200 is over-extruded with the side wall of the cleaning tank 16, and the mop 200 will have a bulging effect, resulting in a partial area being separated from the bottom surface 101 of the cleaning tank 16. The isolation amount is very large, which affects the cleaning effect. The test data is shown in Table 2 below.

[0198] Table 2 (y = 1 mm (1 / 6.5 of the mop thickness))

[0199] 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％

[0200] Optionally, in the embodiment shown in the figure, the cleaning groove 16 is surrounded by baffles (a first baffle 12 and a second baffle 26), and the distance between the edge of the mop 200 and the side wall of the cleaning groove 16 includes the distance between the edge of the mop 200 and the surface of the first baffle 12 facing the cleaning groove 16, and the distance between the edge of the mop 200 and the surface of the second baffle 26 facing the cleaning groove 16.

[0201] In some embodiments, the cleaning tank structure 100 is configured such that when the mop 200 is placed in the cleaning tank 16 , the amount of compression between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0,10] mm.

[0202] In this way, the amount of compression between the edge of the mop 200 and the side wall of the cleaning tank 16 can achieve the desired cleaning effect.

[0203] Specifically, when the mop 200 is placed in the cleaning tank 16 and rotates on the scraper bar 28 for cleaning, the edge of the mop 200 can contact a portion of the side wall of the cleaning tank 16 (such as Fig.24Optionally, the extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0,10] mm, for example, the extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 16 can be 10 mm, 9.8 mm, 9.5 mm, 9 mm, 8.5 mm, 8 mm or other values ​​less than 10 mm. The extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 16 can be specifically determined according to actual needs, and the present invention does not specifically limit this.

[0204] The range of the extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 16 is (0, 10] mm. When the extrusion between the mop 200 and the side wall of the cleaning tank 16 reaches the maximum extrusion amount, the friction between the mop 200 and the side wall of the cleaning tank 16 is the largest, which is conducive to the mutual cleaning of the edge of the mop 200 and the side wall of the cleaning tank 16. It should be noted that when the maximum extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 16 is in the range of (0, 10] mm, the mop 200 can still rotate (that is, the motor of the cleaning robot can still drive the mop 200 to rotate), and will not cause the motor to overload and will not affect the cleaning of the mop 200 rotation.

[0205] Optionally, the extrusion amount of the mop 200 in the vertical direction is fixed, and the maximum compression amount and the maximum isolation amount between the mop 200 and the side wall of the cleaning tank 16 in the horizontal direction are explored.

[0206] Please combine Fig.28 , because the squeezing amount of the mop 200 in the vertical direction is more important to the cleaning effect, when the squeezing amount of the mop 200 in the vertical direction is relatively large (close to the critical value, y=6.0mm, the squeezing amount is equal to the thickness of the mop 200 6.0 / 6.5), when the mop 200 meets the cleaning requirements, in the horizontal direction x range, and explore whether the y value has an impact on the x range that meets the cleaning requirements.

[0207] from Fig.28 It can be seen that when y=6.0mm, -8<=x<=10, the cleaning effect F>=90%, which meets the cleaning requirements. At the same time, compared with Table 1, it is found that the y value has no obvious effect on the x range that meets the cleaning requirements. Because the y value mainly affects the cleaning effect in the vertical direction, when the y value reaches the cleaning requirements, it will not have a significant effect on the effective value of x. The test data is shown in Table 3 below.

[0208] Table 3 (y = 6.0 mm) (mop thickness 6.0 / 6.5)

[0209] 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％

[0210] Optionally, when the mop 200 and the side wall of the cleaning tank 16 reach the maximum squeezing amount, and the mop 200 and the bottom surface 101 of the cleaning tank 16 reach the maximum squeezing amount, the mop 200 can still rotate (that is, the motor of the cleaning robot can still drive the mop 200 to rotate), and will not cause the motor to overload and will not affect the cleaning of the mop 200 rotation.

[0211] It should be noted that the test data is the data obtained by taking the average value after multiple tests in which the thickness of the mop 200 is 6.5 mm.

[0212] In some embodiments, please combine Fig.31 and Fig.32 The cleaning tank structure 100 includes a water inlet hole 24 and a water outlet hole 30. The bottom surface 101 of the cleaning tank 16 connects the water inlet hole 24 and the water outlet hole 30. The bottom surface 101 of the cleaning tank 16 is inclined along the water inlet hole 24 toward the water outlet hole 30. The bottom surface 101 of the cleaning tank 16 is conical. The non-contact area 84 includes at least a part of the circular area T0. The circular area T0 is a circular area formed with a center of the bottom surface 101 of the cleaning tank 16 as the center and a preset radius.

[0213] Therefore, the bottom surface 101 of the cleaning tank 16 can be formed in a conical shape, and the cleaning effect requirement of the non-contact area 84 can be met.

[0214] Specifically, the bottom surface 101 of the conical cleaning tank 16 is inclined along the water inlet 24 toward the water outlet 30, and the lowest point of the bottom surface 101 of the cleaning tank 16 is the position connected to the water outlet 30. When the mop 200 is placed in the cleaning tank 16, the mop 200 is spaced from at least a portion of the circular area.

[0215] exist Fig.32 In the figure, the left cleaning tank 16 is taken as an example for explanation. Since the circular area T0 is a circular area formed with the center of the bottom surface 101 of the cleaning tank 16 as the center O and with a preset radius, and the bottom surface 101 of the cleaning tank 16 is conical, the circular area T0 in the middle of the bottom surface 101 of the cleaning tank 16 is lower than the edge of the bottom surface 101 of the cleaning tank 16. Compared with the edge of the bottom surface 101 of the cleaning tank 16, the circular area T0 forms a depression, which can accumulate a certain amount of water flow, and then the non-contact area 84 can be cleaned to meet the cleaning effect requirements. It can be understood that the preset radius of the circular area T0 is smaller than the radius of the cleaning tank 16.

[0216] Optionally, in Fig.32In the embodiment, the mop 200 has an opening in the middle, and the bottom surface 101 of the cleaning tank 16 exposed by the opening can also be cleaned by the water flow thrown out by the rotating mop 200 or the fluff 202 of the mop 200, thereby meeting the cleaning effect requirements. Optionally, in other embodiments, the mop 200 may not have an opening in the middle.

[0217] The preset radius can be specifically limited according to needs, and the present invention does not make any specific limitation on this.

[0218] In some embodiments, the scraper strip 28 divides the bottom surface 101 of the cleaning tank 16 into a first bottom surface area 96 and a second bottom surface area 98;

[0219] The non-contact area 84 includes a first non-contact area 92 and a second non-contact area 94, or a combination of both. The first non-contact area 92 is a portion of a first circular area C1, and the first circular area C1 is a circular area formed with the center of the first bottom area 96 as the center and a first preset radius.

[0220] The second non-contact area 94 is a part of a second circular area C2 . The second circular area C2 is a circular area formed with the center of the second bottom area 98 as the center and with a second predetermined radius.

[0221] Therefore, the scraper strip 28 can be used to divide the bottom surface 101 of the cleaning tank 16 into areas, and the first bottom surface area 96 and the second bottom surface area 98 can be configured separately to meet the cleaning effect requirements of the non-contact area 84.

[0222] Optionally, the scraper bar 28 may be fixed in the cleaning tank 16 , or may be detachably connected to the bottom surface 101 of the cleaning tank 16 .

[0223] Optionally, in Fig.32 In the embodiment, two scraping strips 28 are provided in the cleaning tank 16, and the two scraping strips 28 divide the bottom surface 101 of the cleaning tank 16 into a first bottom surface area 96 and a second bottom surface area 98. Fig.32 In the embodiment, the first bottom surface area 96 is the front bottom surface area, and the second bottom surface area 98 is the rear bottom surface area.

[0224] Optionally, the non-contact area 84 includes a combination of both the first non-contact area 92 and the second non-contact area 94. Optionally, the non-contact area 84 includes the first non-contact area 92 or the second non-contact area 94.

[0225] The first bottom surface area 96 is a portion of the first conical bottom surface, and the second bottom surface area 98 is a portion of the second conical bottom surface. Fig.32In the embodiment, the radius of the circle where the first bottom surface area 96 is located is greater than the radius of the circle where the second bottom surface area 98 is located. Optionally, the radius of the circle where the first bottom surface area 96 is located is less than or equal to the radius of the circle where the second bottom surface area 98 is located.

[0226] The first non-contact area 92 is a part of the first circular area C1. Since the first circular area C1 is a circular area formed with the center of the first bottom area 96 as the center O and the first preset radius, and the first bottom area 96 is a part of the conical bottom surface, the first circular area C1 in the middle of the first bottom area 96 is lower than the edge of the first bottom area 96. Compared with the edge of the first bottom area 96, the first circular area C1 forms a depression, which can accumulate a certain amount of water flow, and then the first non-contact area 92 can be cleaned to meet the cleaning effect requirements. It can be understood that the first preset radius is smaller than the radius of the first bottom area 96.

[0227] The second non-contact area 94 is a part of the second circular area C2. Since the second circular area C2 is a circular area formed with the center of the second bottom area 98 as the center O and the second preset radius, and the second bottom area 98 is a part of the conical bottom surface, the second circular area C2 in the middle of the second bottom area 98 is lower than the edge of the second bottom area 98. Compared with the edge of the second bottom area 98, the second circular area C2 forms a depression, which can accumulate a certain amount of water flow, and then the second non-contact area 94 can be cleaned to meet the cleaning effect requirements. It can be understood that the second preset radius is smaller than the radius of the second bottom area 98.

[0228] Optionally, in Fig.32 In the example, the first preset radius is equal to the second preset radius, and the center of the first circular area C1 coincides with the center of the second circular area C2 ( Fig.32 It can be 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 area C1 and the center of the second circular area C2 may not coincide.

[0229] Optionally, the scraper bars 28 in the cleaning tank 16 are not limited to two, and may be a single one or more than two.

[0230] Please combine Figure 1 and Figure 3 In some embodiments, the cleaning tank structure 100 includes a water inlet hole 24 and a water outlet hole 30, and a plurality of scraping strips 28 are provided in the cleaning tank 16. The plurality of scraping strips 28 and the bottom surface 101 of the cleaning tank 16 form a water supply channel 32, and the water supply channel 32 connects the water inlet hole 24 and the water outlet hole 30.

[0231] In this way, the water inlet 24 can deliver clean water through the water delivery channel 32 , and at the same time, the sewage after cleaning can be discharged from the water outlet 30 through the water delivery channel 32 .

[0232] Specifically, in Figure 1 In the embodiment, the water inlet 24 can be arranged at the left rear side of the cleaning tank structure 100. The water outlet 30 can be arranged at the front side of the cleaning tank structure 100. Compared with the water supply channel 32, the water inlet 24 is located at a higher position, and the water outlet 30 is located at a lower position. The water entering from the water inlet 24 can flow to the water outlet 30 through the water supply channel 32 under the action of gravity.

[0233] exist Figure 1 In the embodiment, the two scraping bars 28 and the bottom surface 101 of the cleaning tank 16 form a water supply channel 32. In one embodiment, the mop 200 can rotate on the scraping bars 28. During the rotation, the mop 200 can be soaked by the clean water in the water supply channel 32. The scraping bars 28 can scrape and wash the soaked mop 200. After scraping and washing, the sewage or stains and other debris can flow into the water outlet 30 through the water supply channel 32, so that the sewage can be discharged through the water outlet 30. It can be understood that in other embodiments, the water supply channel 32 can be formed not only by two scraping bars 28 and the bottom surface 101 of the cleaning tank 16, but also by three, four or other numbers of scraping bars 28 and the bottom surface 101 of the cleaning tank 16, which is not specifically limited here.

[0234] Further, in Figure 3 In the left-right direction, the water supply channel 32 can separate the cleaning tank 16 into a front tank 30 and a rear tank 88, wherein the front tank 30 is arranged at the front side close to the base 78, and the rear tank 88 is arranged at the rear side close to the base 78. The front tank 30 and the scraper bar 28 close to the front tank 30 can form a through opening 90. The bottom surface of the front tank 30 can be connected to the top of the water outlet 30, and the scraper bar 28 close to the front tank 30 scrapes the mop 200, and the wastewater and other debris after scraping can fall into the front tank 30, and finally flow into the water outlet 30 through the through opening 90. The bottom surface of the rear tank 88 can be connected to the top of the water outlet 30, and the scraper bar 28 close to the rear tank 88 scrapes the mop 200, and the wastewater and other debris after scraping can fall into the rear tank 88, and finally flow into the water outlet 30.

[0235] In one embodiment, the water supply channel 32 includes a first section channel 33 and a second section channel 35, and the first section channel 33 and the second section channel 35 are connected in sequence along the direction from the water inlet hole 24 to the water outlet hole 30. Compared with the water inlet hole 24, the depth of the second section channel 35 is greater than or equal to the depth of the first section channel 33.

[0236] In this way, the second section channel 35 has a deeper depth, thereby preventing the mop 200 from causing secondary contamination in the second section channel 35 .

[0237] Specifically, the water supply channel 32 includes a connecting section channel (not shown), which is arranged obliquely between the first section channel 33 and the second section channel 35. The first section channel 33, the connecting section channel and the second section channel 35 are connected in sequence along the direction from the water inlet hole 24 to the water outlet hole 30. Along the direction from the water inlet hole 24 to the water outlet hole 30, the depth of the connecting section channel may be greater than or equal to the depth of the first section channel 33, and the depth of the second section channel 35 may be greater than or equal to the depth of the connecting section channel.

[0238] Optionally, in one embodiment, the connecting section channel may be omitted, and the first section channel 33 may be directly connected to the second section channel 35, such as Fig.30 shown.

[0239] In one embodiment, when the mop 200 rotates so that the scraper 28 scrapes and washes the mop 200, the fluff 202 of the mop 200 can be located in the first section channel 33, and the clean water in the first section channel 33 can clean the fluff 202 of the mop 200. The dirty water after cleaning can flow to the second section channel 35 through the connecting section channel. The second section channel 35 is deeper, so that the mop 200 or the fluff 202 of the mop 200 cannot contact the dirty water in the second section channel 35, thereby avoiding secondary pollution of the mop 200 in the second section channel 35.

[0240] Furthermore, the scraper bar 28 can scrape the garbage (solid garbage: such as granular matter, thread-like matter, sticky matter, debris, etc.; liquid garbage, such as sewage) attached to the mop 200 into the water supply channel 32, and the water in the water supply channel 32 quickly flows out to the water outlet 30 (the water outlet 30 is provided with a filter element 54 for filtering the garbage), thereby achieving the effect of effectively scraping the garbage at high speed, and avoiding scraping the garbage to the bottom surface 101 area of ​​other cleaning grooves 16. Since the water flow speed in the bottom surface 101 area of ​​other cleaning grooves 16 is relatively slow, the garbage may stay, causing the garbage to repeatedly rub against the bottom surface of the mop 200, causing damage to the mop 200, and slowing down the cleaning speed, and worsening the effect. By limiting the depth of the second channel 35 to be greater than or equal to the depth of the first channel 33, when the mop 200 is located on the second channel 35, the scraper 28 contacts the mop 200, but the water flow does not contact the mop 200, thereby avoiding secondary contamination of the mop 200.

[0241] The depth of the first channel 33 refers to the vertical distance from a certain point on the scraper strip 28 to the bottom surface of the first channel 33. The depth of the second channel 35 refers to the vertical distance from a certain point on the scraper strip 28 to the bottom surface of the second channel 35.

[0242] Optionally, the first section channel 33 may include a plurality of first sub-segment channels having different depths and connected end to end, the second section channel 35 may include a plurality of second sub-segment channels having different depths and connected end to end, the depth of the second section channel 35 may be the average depth of the second sub-segment channels, and the depth of the first section channel 33 may be the average depth of the first sub-segment channels.

[0243] In some embodiments, along the direction from the water inlet hole 24 to the water outlet hole 30 , the depth of the first section of the channel 33 gradually increases, and the depth of the second section of the channel 35 gradually increases.

[0244] In this way, along the direction from the water inlet hole 24 to the water outlet hole 30 , the mop 200 is less likely to come into contact with the sewage in the channel.

[0245] Specifically, in one embodiment, along the direction from the water inlet hole 24 to the water outlet hole 30, the depth of the first section channel 33 at the end away from the water inlet hole 24 is greater than the depth of the first section channel 33 at the end close to the water inlet hole 24, and the depth of the first section channel 33 gradually increases from the end close to the water inlet hole 24 to the end away from the water inlet hole 24. In one embodiment, along the direction from the water inlet hole 24 to the water outlet hole 30, the depth of the second section channel 35 at the end close to the water outlet hole 30 is greater than the depth of the second section channel 35 at the end away from the water outlet hole 30, and the depth of the second section channel 35 gradually increases from the end away from the water outlet hole 30 to the end close to the water outlet hole 30, so that the mop 200 is less likely to contact the sewage in the channel.

[0246] Please combine Figure 29 to Figure 30 In some embodiments, the first section of the channel 33 includes a first end 39 and a second end 41, the second section of the channel 35 includes a third end 43 and a fourth end 45, the first end 39 is connected to the water inlet 24, the second end 41 is connected to the third end 43, and the fourth end 45 is connected to the water outlet 30. The depth H1 of the first end 39 is in the range of [1, 5] mm, the depth H2 of the second end 41 and the third end 43 is in the range of [2, 8] mm, the depth H3 of the fourth end 45 is in the range of [5, 15] mm, and H1<=H2<=H3.

[0247] In this way, by determining the depth range of each end of the first section channel 33 and the second section channel 35 , it can be further ensured that the mop 200 is not likely to come into contact with the sewage in the channel.

[0248] Specifically, in one embodiment, the first end 39 is connected to the water inlet hole 24, the second end 41 is connected to the third end 43, and the fourth end 45 is connected to the water outlet hole 30. Thus, water can be discharged into the water outlet hole 30. Further, by setting the depth H1 range of the first end 39 to be [1, 5] mm, the depth H2 range of the second end 41 and the third end 43 to be [2, 8] mm, and the depth H3 range of the fourth end 45 to be [5, 15] mm, such that H1 <= H2 <= H3, it is further ensured that the mop 200 is not easily in contact with the sewage in the channel.

[0249] The depth H1 of the first end 39 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or other values between 1 mm and 5 mm.

[0250] The depth H2 of the second end 41 and the third end 43 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or other values between 2 mm and 8 mm.

[0251] The depth H3 of the fourth end 45 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, or other values between 5 mm and 15 mm.

[0252] Combined with Fig.30 , it is necessary to ensure that the mop 200 at the depth H1 of the first end 39 to the depth H2 of the second end 41 can contact the water in the water supply channel 32, and the mop 200 cannot completely block the water supply channel 32. The mop 200 at the depth H3 of the fourth end 45 needs to ensure that it is not in contact with the sewage in the water supply channel 32. The values of H1, H2, and H3 are related to the height L1 of the squeegee 28, the squeezing amount y of the mop 200 and the bottom surface 101 of the cleaning tank 16 in the vertical direction, and the water flow height M in the water supply channel 32.

[0253] The gap L0 between the mop 200 and the top of the water supply channel 32 = H1 - L1 - y; for H1 = L1 + y + L0, to satisfy that the mop 200 can be wetted by water at H1 and does not block the water supply channel 32, 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 mop 200 is not in contact with the sewage in the water supply channel 32, that is, L0 > M, that is, H3 > L1 + y + M, and it is necessary to have H1 < H2 < H3. When L1 = 1, y = 2, M = 3 (unit: mm), 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.
