[0061] In the related art, a plurality of scraping bars are arranged in the cleaning tank of the base station. When the mop is cleaned, the mop is placed on the scraping bars. When the mop rotates, it can generate relative motion with the scraping bars, so that the scraping bars scrape and clean the mop. However, the scraping bars that are inclined to each other may form a dead corner where stains are hidden at the intersection, and the stains are also easily hidden in the position between the parallel scraping bars. After long-term use, the cleaning tank is prone to accumulation of stains, and the stains are difficult to clean, causing the cleaning tank to stink.

[0062] Please refer to Figures 1 to 3 A cleaning tank structure 100 according to an embodiment of the present invention comprises a cleaning tank 12, a drainage channel 14 and a movable filter element 16. The drainage channel 14 has a mounting opening 18 formed on the top surface of the cleaning tank structure 100, and the drainage channel 14 comprises a filter section 20 and a flow channel section 22 which are interconnected.

[0063] The filter element 16 includes a filter portion 24 and a flow channel portion 26 connected to each other, and the filter element 16 can be switched between a first position and a second position through the mounting port 18. In the first position, the filter portion 24 is located at the filter section 20, the flow channel portion 26 is located at the flow channel section 22, and the flow channel section 22 is connected to the cleaning tank 12 through the filter portion 24. In the second position, the filter portion 24 is located outside the filter section 20, and the flow channel portion 26 is located outside the flow channel section 22.

[0064] In the above-mentioned cleaning tank structure 100, when the filter element 16 is in the first position, the water in the cleaning tank 12 can flow into the flow channel section 22 through the filter portion 24, and then the water in the cleaning tank 12 can be filtered. When the filter element 16 is in the second position, the filter portion 24 is located outside the filter section 20, and the flow channel portion 26 is located outside the flow channel section 22, so that the user can easily clean the drainage channel 14 through the installation port 18, thereby avoiding the problem of stains remaining in the drainage channel 14 causing the cleaning tank structure 100 to stink.

[0065] Specifically, the cleaning tank structure 100 can be used in conjunction with a cleaning robot. The cleaning robot includes a body and a mop 200, which can be installed at the bottom of the body. When the mop 200 of this embodiment rotates, the rotation axis of the mop 200 is substantially perpendicular to the bottom of the body.

[0066] In the embodiment shown in the figure, the cleaning tank 12 is similar to a circular shape, and can be adapted to a circular mop 200, so that the mop 200 can be cleaned in the cleaning tank 12. The cleaning tank 12 similar to a circular shape can also be adapted to a triangular mop 200. It can be understood that in one embodiment, when the rotation center of the mop 200 remains unchanged, whether the shape of the mop 200 is a triangle, a quadrilateral or other polygon, the cleaning tank 12 can be set to be similar to a circular shape to match the mop 200. In another embodiment, when the rotation center of the mop 200 changes, the cleaning tank 12 can be irregularly shaped, but the cleaning tank 12 is adapted to the mop 200, so that the mop 200 can be cleaned in the cleaning tank 12.

[0067] Optionally, when the cleaning tank structure 100 is provided with a single cleaning tank 12, it can be used in combination with a cleaning robot having a single mop 200, and the single mop 200 can rotate in the cleaning tank 12 along the clockwise direction R1 or the counterclockwise direction R2, and the present invention does not make any specific limitation on this.

[0068] Optionally, when the cleaning tank structure 100 is provided with two cleaning tanks 12, it can be used in combination with a cleaning robot having two mops 200. The two mops 200 respectively placed in the two cleaning tanks 12 can rotate in the same direction or in different directions during cleaning. Figure 4In one embodiment, the mop 200 placed in the left cleaning tank 12 can rotate in the clockwise direction R1, and the mop 200 placed in the right cleaning tank 12 can rotate in the counterclockwise direction R2. In one embodiment, the mop 200 placed in the left cleaning tank 12 can rotate in the counterclockwise direction R2, and the mop 200 placed in the right cleaning tank 12 can rotate in the clockwise direction R1. The utility model does not specifically limit this. It can be understood that one or more mops 200 can be placed in a cleaning tank 12 for cleaning, and the utility model does not specifically limit the number of cleaning tanks 12.

[0069] Optionally, in one embodiment, the filter portion 24 is provided with a filter cavity 28 , a filter hole 30 is provided at the bottom of the filter cavity 28 , and the flow channel section 22 is connected to the cleaning tank 12 through the filter hole 30 and the filter cavity 28 .

[0070] Specifically, when the cleaning tank 12 cleans the mop 200, the mop 200 rotates in the cleaning tank 12. The filter element 16 is located at the first position, and the sewage formed by cleaning the mop 200 falls into the cleaning tank 12 and flows to the filter cavity 28, and then flows into the flow channel section 22 after being filtered by the filter hole 30, and then the drainage channel 14 can drain the sewage in the cleaning tank 12. When the drainage channel 14 needs to be cleaned, the filter 16 can be switched from the first position to the second position through the installation port 18, so that the filter part 24 is located outside the filter section 20, and the flow channel part 26 is located outside the flow channel section 22. The drainage channel 14 is open, and the user can directly clean and dredge the drainage channel 14 through the installation port 18 on the top surface of the cleaning tank structure to avoid stains remaining in the drainage channel 14 and causing the cleaning tank structure 100 to stink and the drainage channel 14 to be blocked. Moreover, compared with forming the drainage channel 14 integrally inside the cleaning tank structure 100, the open drainage channel 14 improves the convenience of users cleaning the drainage channel 14, thereby satisfying the user's experience and improving product reliability. In addition, the solid waste filtered by the filter 16 is collected and dumped by the filter 16, and the filter 16 can also be installed in a detachable manner, which can more effectively clean solid and liquid waste.

[0071] Alternatively, in one embodiment, the filter element 16 may be an integral structural member, that is, each part including the filter portion 24 and the flow channel portion 26 is connected to form an integral structure. For example, the filter element 16 may be made of plastic, and the filter element 16 may be integrally manufactured by an injection molding process. Alternatively, in one embodiment, the filter element 16 may be a split structural member, that is, each part including the filter portion 24 and the flow channel portion 26 may be manufactured separately, and then assembled together to form the filter element 16. The present invention does not specifically limit this.

[0072] Optionally, the filter element 16 can be movable in at least one of a rotating, sliding and detachable manner, which is not specifically limited in the present invention, and thus the installation manner of the filter element 16 can be flexibly selected. The detachable manner may mean that after the filter element 16 is installed in the cleaning tank structure 100, the filter element 16 can be removed from the cleaning tank structure 100 in a detachable manner without damaging the filter element 16, so that the drainage channel 14 and the filter element 16 can be cleaned. After cleaning, the filter element 16 can be installed back.

[0073] Optionally, in one embodiment, the filter element 16 can also be directly disassembled to switch positions without the need for rotation (such as flipping) to switch positions.

[0074] Optionally, the filter element 16 is detachable relative to the drainage channel 14 .

[0075] Optionally, the flow channel portion 26 includes a top plate 32, a first side plate 34, and a second side plate 36, wherein the first side plate 34 and the second side plate 36 are respectively connected to both sides of the top plate 32 along the first direction. Figure 3 In the figure, the first direction is the left-right direction, the first side plate 34 is the left side plate, and the second side plate 36 is the right side plate. The top plate 32, the first side plate 34, and the second side plate 36 form a flow channel 38, and both ends of the flow channel 38 are open ports. When the filter element 16 is in the first position, one end of the flow channel 38 is connected to the filter hole 30, and the water filtered by the filter hole 30 can flow from one end of the flow channel 38 to the other end and flow out of the flow channel 38. The top plate 32 is opposite to the bottom surface of the flow channel section 22. Please refer to the figure below. Figure 3 and Figure 5 The space occupied by the flow channel 38 is a part of the space of the flow channel section 22. Therefore, when the filter element 16 is located at the second position, the flow channel 38 can be cleaned through the opening toward the top plate 32, and the flow channel portion 26 can also be cleaned.

[0076] Optionally, combine Figure 2 and Figure 3 In order to improve the stability of the filter element 16 when installed in the cleaning tank structure 100, a first clamping portion 40 is protruding from the side wall of the filter section 20, and a second clamping portion 42 is protruding from the side wall of the filter portion 24. When the filter element 16 is in the first position, the first clamping portion 40 limits the second clamping portion 42 to prevent the filter element 16 from accidentally detaching from the drainage channel 14.

[0077] Optionally, in order to facilitate the user to operate the filter element 16 (such as moving, rotating, disassembling, etc.), a handle 44 is further provided on the filter part 24.

[0078] Optionally, the filter element 16 and the second clamping portion 42 can be removed as a whole to clean the garbage on the filter element 16 .

[0079] In some embodiments, the top surface of the flow channel portion 26 is inclined toward the filter portion 24 .

[0080] This helps to guide the accumulated water on the top surface of the flow channel portion 26 to the filter portion 24 .

[0081] Specifically, when the mop 200 is cleaned in the cleaning tank 12, water will be thrown from the mop 200 to the flow channel portion 26. The top surface of the flow channel portion 26 is inclined in the filtering direction, so that the water falling to the top surface of the flow channel portion 26 can flow to the filter portion 24 and enter the filter cavity 28, thereby avoiding water residue on the flow channel portion 26.

[0082] In some embodiments, the cleaning tank structure 100 includes a mounting portion 46, and the filter element 16 is rotatably connected to the mounting portion 46. The filter element 16 switches between the first position and the second position by rotating.

[0083] Thus, the filter element 16 can be switched in position by rotating.

[0084] Specifically, please combine Figure 1 , the filter element 16 is located in the first position. When the filter element 16 rotates from the first position to the second position, the filter element 16 rotates around the mounting portion 46, so that the filter element 16 switches to the second position, such as Figure 2 or Figure 3 shown.

[0085] Optionally, when the filter element 16 is rotatably connected to the mounting portion 46 , the filter element 16 may not be removed.

[0086] Optionally, in Figure 2 and Figure 3 In the embodiment, the filter element 16 is in the shape of an elongated strip, and one end of the filter element 16 is rotatably connected to the mounting portion 46, thereby facilitating the filter element 16 to open the drainage channel 14 at a large angle.

[0087] Optionally, the mounting portion 46 may be disposed on the edge of the mounting opening 18 , which facilitates the installation of the filter element 16 and the mounting portion 46 .

[0088] In some embodiments, the filter element 16 is provided with a connecting portion 48 , the connecting portion 48 includes a rotating shaft 50 , the mounting portion 46 is provided with an axial hole 52 , and the rotating shaft 50 is rotatably located in the axial hole 52 .

[0089] Thus, the filter element 16 can be rotated relative to the mounting portion 46 through the cooperation between the rotating shaft 50 and the shaft hole 52 .

[0090] Specifically, in Figure 3In the embodiment, the connection portion 48 connects one end of the first side plate 34 and one end of the second side plate 36, and extends in a direction away from the filter section 20. The connection portion 48 includes two rotating shafts 50, one is a left rotating shaft 50, and the other is a right rotating shaft 50. The mounting portion 46 includes a first sub-portion 54 (such as a left sub-portion) and a second sub-portion 56 (such as a right sub-portion). The two sub-portions are respectively mounted on two opposite edges of the mounting opening 18, and the two sub-portions are spaced and opposite to each other. The first sub-portion 54 is provided with an axial hole 52 on the side facing the second sub-portion 56, and the second sub-portion 56 is provided with another axial hole 52 on the side facing the first sub-portion 54. The two rotating shafts 50 are rotatably located in the two axial holes 52, respectively. Therefore, the mounting portion 46 has a good support and rotation effect on the filter element 16.

[0091] In some embodiments, please combine Figure 3 and Figure 5 The mounting portion 46 is provided with a disassembly and assembly passage 58, which is connected to the shaft hole 52. When the filter element 16 is located in the first position, the rotating shaft 50 is located in the shaft hole 52. During the process of switching the filter element 16 from the first position to the second position, the rotating shaft 50 is separated from the shaft hole 52 and the mounting portion 46 through the disassembly and assembly passage 58, so that the filter element 16 is removed from the mounting portion 46.

[0092] Thus, more position switching modes of the filter element 16 can be provided.

[0093] Specifically, in one embodiment, the position switching mode of the filter element 16 can be a rotation mode. Figure 1 In the embodiment, the filter element 16 is located in the first position. When the filter element 16 is switched from the first position to the second position, the filter element 16 can be rotated upward to the second position, such as Figure 2 At this time, the filter element 16 opens the drainage channel 14. Figure 2 In the embodiment, the filter element 16 is located in the second position. When the filter element 16 is switched from the second position to the first position, the filter element 16 can be rotated downward to the first position, such as Figure 1 At this time, the filter element 16 blocks the drainage channel 14.

[0094] In one embodiment, the position switching mode of the filter element 16 can be a direct disassembly mode. Figure 1 In the embodiment, the filter element 16 is located in the first position. When the filter element 16 is switched from the first position to the second position, the filter element 16 can be lifted upward, so that the rotating shaft 50 is separated from the shaft hole 52 and the mounting portion 46 through the disassembly passage 58, and the filter element 16 is located in the second position. At the same time, the filter element 16 is removed from the mounting portion 46. Figure 3 At this time, the filter element 16 opens the drainage channel 14. Figure 3When the filter element 16 is switched from the second position to the first position, the filter element 16 can be lowered downward, so that the rotating shaft 50 is installed into the shaft hole 52 through the disassembly passage 58, and the filter element 16 is in the first position. Figure 1 At this time, the filter element 16 blocks the drainage channel 14.

[0095] In one embodiment, the position switching mode of the filter element 16 can be rotation and disassembly. Figure 1 In the embodiment, the filter element 16 is located in the first position. When the filter element 16 is switched from the first position to the second position, the filter element 16 can be rotated upward to the second position, such as Figure 2 At this time, the filter element 16 opens the drainage channel 14. The filter element 16 can also Figure 2 Continue to lift up to another second position (such as Figure 3 As shown), the filter element 16 can be removed from the mounting portion 46. The filter element 16 can be made to block the drainage channel 14 in the reverse order.

[0096] In some embodiments, the cleaning tank structure 100 includes a mounting portion 46, a connecting portion 48 is provided on the filter element 16, the mounting portion 46 is provided with a disassembly channel 58 and a mounting hole, the disassembly channel 58 is connected to the mounting hole, and when the filter element 16 is in the first position, the connecting portion 48 is located in the mounting hole. During the process of switching the filter element 16 from the first position to the second position, the connecting portion 48 is detached from the mounting hole and the mounting portion 46 through the disassembly channel 58, so that the filter element 16 is removed from the mounting portion 46.

[0097] Thus, the first position and the second position of the filter element 16 can be switched by direct disassembly.

[0098] Specifically, in this embodiment, the filter element 16 can be connected to the mounting portion 46 without rotation. Figure 1 , the filter element 16 is located in the first position. When the filter element 16 is switched from the first position to the second position, the filter element 16 can be lifted upward, so that the connecting portion 48 is separated from the mounting hole and the mounting portion 46 through the disassembly passage 58, and the filter element 16 is located in the second position. At the same time, the filter element 16 is removed from the mounting portion 46 (can be combined with Figure 3 At this time, the filter element 16 opens the drainage channel 14. When the filter element 16 switches from the second position to the first position, the filter element 16 can be lowered downward, so that the connecting portion 48 is installed into the installation hole through the disassembly channel 58, and the filter element 16 is in the first position (which can be combined with Figure 1 At this time, the filter element 16 blocks the drainage channel 14.

[0099] In some embodiments, the drainage channel 14 includes a sewage suction section 60 , which is connected to the filter section 20 through the flow channel section 22 , and the drainage channel 14 is inclined from the filter section 20 to the sewage suction section 60 .

[0100] Thus, the sewage in the cleaning tank 12 can be collected in the sewage suction section 60, which is convenient for the base station to suck and discharge the sewage.

[0101] Specifically, the sewage in the cleaning tank 12 flows into the flow channel section 22 through the filter cavity 28 and the filter hole 30, and then flows into the sewage suction section 60. The drainage channel 14 is inclined from the filter section 20 to the sewage suction section 60, so that the sewage can be collected in the sewage suction section 60. The base station can use the sewage suction pipe to extend into the sewage suction section 60 through the installation port 18 to suck and discharge the sewage.

[0102] In some embodiments, the cleaning tank structure 100 includes a detection channel 62, which is connected to the end of the sewage suction section 60 away from the flow channel section 22 and is communicated with the sewage suction section 60. The cleaning tank structure 100 includes a liquid level detection component 64, which is arranged at a position where the depth of the detection channel 62 is not the maximum.

[0103] Therefore, the liquid level detection component 64 can be used to detect the water level, thereby facilitating the sewage suction and discharge operations of the base station.

[0104] Specifically, the detection channel 62 is connected to the sewage suction section 60 . When sewage accumulates in the sewage suction section 60 , the sewage will also flow into the detection channel 62 .

[0105] The liquid level detection component 64 is arranged at a position where the depth of the detection channel 62 is not the maximum. Only after a certain amount of water is stored in the sewage suction section 60, the water reaches the position of the liquid level detection component 64, and the liquid level detection component 64 outputs a liquid level signal to enable the base station to perform sewage suction and discharge operations, thereby avoiding the sewage suction and discharge operation of the base station being triggered by less water in the sewage suction section 60, and reducing the probability of false alarms.

[0106] In some embodiments, the length direction of the detection channel 62 is substantially perpendicular to the length direction of the drainage channel 14 .

[0107] This helps to maintain the compactness of the cleaning tank structure 100.

[0108] Specifically, in the embodiment shown in the figure, the cleaning tank structure 100 includes two cleaning tanks 12 connected side by side, and the two cleaning tanks 12 share a drainage channel 14 and a filter 16. There are two detection channels 62, namely a left detection channel 62 and a right detection channel 62. The two detection channels 62 and the drainage channel 14 constitute a T-shaped channel. The T-shaped channel can make full use of the lateral space (such as the left and right direction space) and the longitudinal space (such as the front and back direction space) of the cleaning tank structure 100, avoiding the cleaning tank structure 100 from occupying too much space in one direction, thereby facilitating the compactness of the cleaning tank structure 100.

[0109] Optionally, in Figure 3 In the figure, the liquid level detection assembly 64 includes a first detection member 66 and a second detection member 68, which are respectively arranged in two detection channels 62, and the first detection member 66 and the second detection member 68 are located at the same depth of the detection channels 62. When the water level reaches the first detection member 66 and the second detection member 68, the water will electrically connect the first detection member 66 and the second detection member 68, thereby connecting the liquid level detection circuit of the base station, generating a liquid level signal, and causing the base station to perform sewage suction and discharge operations.

[0110] Optionally, the first detection member 66 and the second detection member 68 may be disposed in one detection channel 62 .

[0111] Optionally, in one embodiment, the cleaning tank structure 100 includes a single cleaning tank 12, and the drainage channel 14 is connected to the detection channel 62 in an L-shaped structure, which is also conducive to maintaining the compactness of the cleaning tank structure 100. It can be understood that the utility model does not specifically limit the number of detection channels 62 and the number of cleaning tanks 12.

[0112] Optionally, in one embodiment, the two detection members of the liquid level detection assembly 64 can be connected together by an insulating structural member, and the two detection members are spaced apart. When the liquid level reaches the liquid level detection assembly 64, water flows into the gap between the two detection members, so that the two detection members are electrically connected. The present utility model does not specifically limit the specific structure and detection principle of the liquid level detection assembly 64.

[0113] The length direction of the detection channel 62 is substantially perpendicular to the length direction of the drainage channel 14. The length direction of the detection channel 62 is completely perpendicular to the length direction of the drainage channel 14. Alternatively, the difference between the angle between the length direction of the detection channel 62 and the length direction of the drainage channel 14 and the right angle is within the desired range.

[0114] In some embodiments, the depth of the detection channel 62 gradually decreases from one end of the detection channel 62 connected to the sewage suction section 60 to the other end away from the sewage suction section 60, and the liquid level detection component 64 is arranged at the end of the detection channel 62 away from the sewage suction section 60.

[0115] In this way, the liquid level detection component 64 is disposed at the position farthest from the dirt suction section 60 , and the liquid level detection component 64 is located at the shallowest part of the detection channel 62 , which can further reduce the probability of false alarms.

[0116] Specifically, the depth of the end of the detection channel 62 connected to the sewage suction section 60 is the largest, and the connection between the detection channel 62 and the sewage suction section 60 is the lowest point. The sewage suction pipe can extend into this lowest point, which is conducive to sucking and draining the sewage.

[0117] Sewage begins to gather at the connection between the sewage suction section 60 and the detection channel 62, and the liquid level gradually rises from one end of the detection channel 62 (maximum depth) to the other end (minimum depth). At this time, the water contacts the first detection member 66 and the second detection member 68, so that the first detection member 66 and the second detection member 68 are electrically connected. The sewage suction and discharge operation of the base station is triggered only when the amount of sewage is large, which can further reduce the probability of false alarms.

[0118] In some embodiments, please combine Figure 3 and Figure 6 An opening 70 is provided at one end of the detection channel 62 away from the dirt suction section 60, and the cleaning tank structure 100 is provided with a accommodating cavity 72. The accommodating cavity 72 has a detection port 74 formed on the side wall of the cleaning tank structure 100. The accommodating cavity 72 is connected to the opening 70. The liquid level detection component 64 is partially located in the accommodating cavity 72. The liquid level detection component 64 includes a detection end 76 and an output end 78 that are electrically connected to each other. The detection end 76 is located in the accommodating cavity 72 and exposed from the opening 70, and the output end 78 is provided at the detection port 74.

[0119] Thus, the liquid level detection assembly 64 can be installed in the cleaning tank structure 100 in a semi-hidden manner.

[0120] Specifically, in Figure 3 In the embodiment, the liquid level detection assembly 64 includes a first detection member 66 and a second detection member 68, each detection member includes a detection end 76 and an output end 78, each detection member also includes a mounting seat 80, the detection end 76 and the output end 78 are arranged on the mounting seat 80, and the detection end 76 is electrically connected to the output end 78. The mounting seat 80 can be located in the accommodating cavity 72.

[0121] The cleaning tank structure 100 is provided with two accommodating chambers 72, and the first detection member 66 and the second detection member 68 are respectively installed in the two accommodating chambers 72. Each accommodating chamber 72 is connected to the opening 70 of a corresponding detection channel 62. When the liquid level reaches the opening 70, water contacts the detection ends 76 of the two detection members, so that the two detection ends 76 are electrically connected, and then the two output ends 78 are electrically connected, and the liquid level detection circuit of the base station is turned on, thereby triggering the sewage suction and discharge operation of the base station.

[0122] The output end 78 is disposed at the detection port 74 , which facilitates the liquid level detection circuit to be electrically connected to the output end 78 .

[0123] In some embodiments, a recess 82 is provided at the bottom of the filter portion 24 , and the recess 82 is correspondingly connected to one end of the flow channel section 22 .

[0124] Thus, the concave portion 82 at the bottom of the filter portion 24 corresponds to the flow channel section 22 , which can make it easier for water to flow into the flow channel section 22 .

[0125] Specifically, since the concave portion 8238 is correspondingly connected to one end of the flow channel section 22, the flow channel section 22 can be connected to the space surrounded by the concave portion 82, and the filter portion 24 has no or less shielding on one end of the flow channel section 22, and the sewage flowing out of the filter portion 24 is more likely to flow into the flow channel section 22, and flow out of the cleaning tank structure 100 through the flow channel section 22 and the sewage suction section 60, so that the sewage can be discharged from the cleaning tank 12 in time. The side wall of the concave portion 82 is provided with a filter hole 30. Corresponding to the concave portion 82, a convex hull 84 is formed in the filter cavity 28.

[0126] In some embodiments, please combine Figures 7 and 8 The cleaning tank structure 100 includes a scraper bar 86 , which is located in the cleaning tank 12 , and the bottom surface of the cleaning tank 12 includes a contact area 90 .

[0127] The cleaning tank structure 100 is configured as follows:

[0128] When the mop 200 is placed on the scraper strip 86,

[0129] The contact area 90 is capable of directly contacting the mop 200 both when rotating and when not rotating.

[0130] Therefore, when the mop 200 is placed on the scraper bar 86, the contact area 90 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 90, which can avoid or reduce the debris remaining on the bottom surface of the cleaning tank 12, thereby avoiding the cleaning tank structure 100 from stinking or reducing the chance of the cleaning tank structure 100 stinking.

[0131] Specifically, the cleaning robot includes a body and a mop 200 . The mop 200 can be installed at the bottom of the body. When the mop 200 of this embodiment rotates, the rotation axis of the mop 200 is substantially perpendicular to the bottom of the body.

[0132] In one embodiment, when the mop 200 of the cleaning robot needs to be cleaned, the cleaning robot can enter the base station, and the mop 200 can be placed on the scraper bar 86, and the contact area 90 can directly contact the mop 200 when it is not rotating.

[0133] While the scraper bar 86 is scraping the mop 200, the rotating mop 200 can also directly contact the contact area 90. In the process of cleaning the mop 200, the rotating mop 200 can also clean the contact area 90, thereby avoiding or reducing the debris remaining on the bottom surface of the cleaning tank 12, thereby avoiding the cleaning tank structure 100 from stinking or reducing the chance of the cleaning tank structure 100 stinking.

[0134] Alternatively, in one embodiment, the entire bottom surface of the cleaning tank 12 may be the contact area 90, that is, when the mop 200 is placed on the scraper bar 86, the entire bottom surface of the cleaning tank 12 can directly contact the mop 200 when it is rotating or not rotating. Alternatively, in one embodiment, a portion of the bottom surface of the cleaning tank 12 may be the contact area 90.

[0135] Optionally, combine Figure 4 The scraping strip 86 extends in the radial direction of the cleaning tank 12 , so that the scraping strip 86 is longer and the contact area with the mop 200 is larger, thereby improving the scraping and cleaning effect on the mop 200 .

[0136] Optionally, the scraper bar 86 is connected to the cleaning tank 12 as an integral structure, thereby the cleaning tank structure 100 has low cost and high rigidity. For example, the cleaning tank structure 100 can be integrally manufactured using an injection molding process, so that the scraper bar 86 is connected to the cleaning tank 12 as an integral structure. Optionally, the scraper bar 86 is detachably connected to the cleaning tank 12.

[0137] The cleaning tank structure 100 shown in the figure is provided with two cleaning tanks 12, 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 12, which can be adapted to a cleaning robot with a single turntable cleaning member.

[0138] Optionally, in Figure 7 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.

[0139] In some embodiments, please combine Fig. 9The bottom surface of the cleaning tank 12 includes a non-contact area 92, and the cleaning tank structure 100 is configured as follows: when the mop 200 is placed on the scraper bar 86, the vertical distance W between the non-contact area 92 and the plane P where the mop 200 is located is in the range of (0,3] mm.

[0140] In this way, during the process of cleaning the mop 200 , the mop 200 can drive the water flow to the non-contact area 92 when rotating to clean the non-contact area 92 .

[0141] Specifically, the bottom surface of the cleaning tank 12 also includes a non-contact area 92. When the scraper bar 86 scrapes the mop 200, the vertical distance W between the non-contact area 92 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 200, the mop 200 can drive the water flow to the non-contact area 92 when rotating to clean the non-contact area 92.

[0142] In some embodiments, the vertical distance W between the non-contact area 92 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 92 and the plane P where the mop 200 is located can be specifically determined according to actual needs, and the present invention does not make specific limitations on this.

[0143] Optionally, in Fig.10 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 92 and the plane P where the mop 200 is located may be the vertical distance between the non-contact area 92 and the bottom surface of the fluff 202 .

[0144] Optionally, both the contact area 90 and the non-contact area 92 are planes. In one embodiment, the contact area 90 may be an inclined surface, and the non-contact area 92 may also be an inclined surface, and the slope of the non-contact area 92 is greater than the slope of the contact area 90. In one embodiment, the slope of the non-contact area 92 may also be less than the slope of the contact area 90. In one embodiment, the contact area 90 may be a horizontal surface, and the non-contact area 92 may also be a horizontal surface. In one embodiment, the contact area 90 may be a horizontal surface, and the non-contact area 92 may be an inclined surface. In one embodiment, the contact area 90 may be an inclined surface, and the non-contact area 92 may be a horizontal surface. In one embodiment, the contact area 90 may be an inclined surface, and the non-contact area 92 may be an inclined surface, and the slope of the non-contact area 92 is equal to the slope of the contact area 90. The contact area 90 may be a curved surface or an arc surface, the non-contact area 92 may also be a curved surface or an arc surface, the contact area 90 may be a plane and the non-contact area 92 may be a curved surface or an arc surface, or the non-contact area 92 may be a plane and the contact area 90 may be a curved surface or an arc surface. In summary, when the mop 200 is placed on the scraper bar 86, the vertical distance W between the non-contact area 92 and the plane P where the mop 200 is located is in the range of (0,3] mm.

[0145] Please refer to 12. It can be seen from the effect diagram that when the vertical distance W between the non-contact area 92 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 of the cleaning tank 12, the rotating mop 200 can also have the desired cleaning effect on the non-contact area 84, reducing the probability of the cleaning tank structure 100 stinking.

[0146] Specifically, in Fig.12 In the figure, y represents the vertical extrusion amount between the mop 200 and the bottom surface of the cleaning tank 12, in mm. When y<0, it means that the mop 200 is isolated from the bottom surface of the cleaning tank 12. 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 12 is weighed, and F=1-z / 5×100%. After one self-cleaning, F>=90% of the cleaning effect meets the cleaning requirements.

[0147] from Fig.12It can be seen that when y>=-3 (that is, 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 12 to flow when rotating, and the cleaning tank 12 is rinsed by the water flow, thereby achieving the effect of cleaning the cleaning tank 12. When y>0, there is extrusion between the mop 200 and the bottom surface of the cleaning tank 12, and the friction between the mop 200 and the bottom surface of the cleaning tank 12 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 of the cleaning tank 12 cannot be obtained. 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 12, and the better the cleaning effect of the cleaning tank 12.

[0148] Table 1

[0149] 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 (2 / 3 of the total thickness of the mop) 0 100％ 6.0 (100% of mop thickness) 0 100％

[0150] In some embodiments, please combine Fig.10 The range of the extrusion amount between the mop 200 and the bottom surface of the cleaning tank 12 is [0, T) mm, where T is the thickness of the mop 200.

[0151] In this way, the amount of squeezing between the mop 200 and the bottom surface of the cleaning tank 10 meets the cleaning effect requirements.

[0152] 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 of the cleaning tank 10 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 of the cleaning tank 10, the greater the friction between the mop 200 and the bottom surface of the cleaning tank 10, and the better the cleaning effect. It should be noted that when the amount of extrusion between the mop 200 and the bottom surface of the cleaning tank 10 is close to the thickness T of the mop 200, the friction between the mop 200 and the bottom surface of the cleaning tank 10 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.

[0153] In some examples, the amount of compression between the mop 200 and the bottom surface of the cleaning tank 10 may 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), which are not specifically limited in the present invention. The amount of compression between the mop 200 and the bottom surface of the cleaning tank 10 is 0 mm, indicating that the contact surface between the fluff 202 and the bottom surface of the cleaning tank 10 is not compressed.

[0154] In some embodiments, please combine Fig. 9The cleaning tank structure 100 is configured such that when the mop 200 is placed in the cleaning tank 12, the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 12 is in the range of (0,8] mm.

[0155] In this way, the water carried by the mop 200 is thrown to the side wall of the cleaning tank 10 under the action of centrifugal force, so that the side wall of the cleaning tank 10 is cleaned.

[0156] Specifically, when the mop 200 is placed in the cleaning tank 10 and rotates on the scraper bar 14 for cleaning, the edge of the mop 200 can contact a part of the side wall of the cleaning tank 10 (such as Fig. 9 The horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 10 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 10 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 10 can be specifically determined according to actual needs, and the utility model does not make specific limitations on this.

[0157] When the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 10 is in the range of (0,8] mm, when the mop 200 rotates on the scraper bar 14 for cleaning, the water carried by the mop 200 is thrown to the side wall of the cleaning tank 10 under the action of centrifugal force, and the water can clean the side wall of the cleaning tank 10, thereby achieving the cleaning of the side wall of the cleaning tank 10. In addition, when the horizontal distance U between the edge of the mop 200 and the side wall of the cleaning tank 10 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 10, which is easy to position.

[0158] Please combine Fig.13 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 10 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 10, the rotating mop 200 can still have the desired cleaning effect on the non-contacting side wall area of ​​the cleaning tank 10, reducing the probability of the cleaning tank structure 100 stinking.

[0159] Specifically, in Fig.13In the figure, x represents the horizontal extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 10 (if there is a baffle, it is the surface of the baffle facing the cleaning tank 10), 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 10. 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 10 is weighed, and F=1-z / 5×100%. After one self-cleaning, F>=90% of the cleaning effect meets the cleaning requirements.

[0160] In this test, the y value is fixed, such as setting y = 1mm. Fig.13 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 10 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 10 by relying on the water flow and the fluff 202. There is a blind spot and the cleaning effect is not good. When x>10, the mop 200 is over-extruded with the side wall of the cleaning tank 10, and the mop 200 will have a bulging effect, resulting in a partial area separated from the bottom surface of the cleaning tank 10. The isolation amount is very large, affecting the cleaning effect. The test data is shown in Table 2 below.

[0161] Table 2 (y = 1 mm (1 / 6.5 of the mop thickness))

[0162] 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％

[0163] In some embodiments, the cleaning tank structure 100 is configured such that when the mop 200 is placed in the cleaning tank 12, the amount of compression between the edge of the mop 200 and the side wall of the cleaning tank 12 is in the range of (0, 10] mm.

[0164] In this way, the amount of compression between the edge of the mop 200 and the side wall of the cleaning tank 10 can achieve the desired cleaning effect.

[0165] Specifically, when the mop 200 is placed in the cleaning tank 10 and rotates on the scraper bar 14 for cleaning, the edge of the mop 200 can contact a part of the side wall of the cleaning tank 10 (such as Fig. 9 Optionally, the extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 10 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 10 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 10 can be specifically determined according to actual needs, and the present invention does not make any specific limitation on this.

[0166] The range of the extrusion amount between the edge of the mop 200 and the side wall of the cleaning tank 10 is (0, 10] mm. When the extrusion amount between the mop 200 and the side wall of the cleaning tank 10 reaches the maximum, the friction between the mop 200 and the side wall of the cleaning tank 10 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 10. 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 10 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.

[0167] 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 10 in the horizontal direction are explored.

[0168] Please combine Fig.14 , 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.

[0169] from Fig.14 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.

[0170] Table 3 (y = 6.0 mm) (mop thickness 6.0 / 6.5)

[0171] 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％

[0172] Optionally, when the mop 200 and the side wall of the cleaning tank 10 reach the maximum squeezing amount, and the mop 200 and the bottom surface of the cleaning tank 10 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.

[0173] 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.

[0174] In some embodiments, the cleaning tank structure 100 includes a base 94 , a first recess 96 is formed on a top surface of the base 94 , and the first recess 96 constitutes the cleaning tank 12 .

[0175] In this way, the cleaning tank 12 can be formed in the base 94 through the first recess 96 , and the structure of the cleaning tank structure 100 is simple.

[0176] Specifically, the top surface 128 may be recessed downward to form a first recess 96, and the first recess 96 may be circular, so that the cleaning tank 12 may be formed on the base 94 through the first recess 96, and the structure of the cleaning tank structure 100 is simple. Optionally, the first recess 96 may be manufactured by an integrated molding process.

[0177] Optionally, one or more cleaning tanks 12 may be formed with one first recess 96. Figure 3 It can be understood that one first recess 96 forms two cleaning grooves 12, or it can be understood that one first recess 96 forms one cleaning groove 12, and the two first recesses 96 are interconnected (that is, the two cleaning grooves 12 are interconnected), and the utility model does not make specific limitations on this.

[0178] Optionally, the drainage channel 14 may be formed by a second recess 98 formed on the bottom surface of the cleaning tank 12 , and the bottom surface of the drainage channel 14 is lower than the bottom surface of the cleaning tank 12 .

[0179] Optionally, in other embodiments, the cleaning tank structure 100 includes baffles, which surround the cleaning tank 12 , and the distance between the edge of the mop 200 and the side wall of the cleaning tank 12 is the distance between the edge of the mop 200 and the surface of the baffle facing the cleaning tank 12 .

[0180] In some embodiments, the cleaning tank structure 100 includes a water inlet hole 102, and a plurality of scraper strips 86 are provided in the cleaning tank 12. The plurality of scraper strips 86 and the bottom surface of the cleaning tank 12 form a water supply channel 106. The water supply channel 106 includes a first section channel 108 and a second section channel 110. The first section channel 108 and the second section channel 110 are connected in sequence along the direction from the water inlet hole 102 to the filter section 20. The water inlet hole 102 is connected to the filter section 20 through the first section channel 108 and the second section channel 110 in sequence. The depth of the second section channel 110 is greater than or equal to the depth of the first section channel 108.

[0181] In this way, the water inlet 102 can transport clean water through the water supply channel 106, and the cleaned sewage can be discharged from the filter section 20 through the water supply channel 106. The depth of the second section channel 110 is deeper, avoiding secondary pollution caused by the mop 200 in the second section channel 110.

[0182] Specifically, in Figure 3In the embodiment, the water inlet 102 of the left washing tank 12 can be arranged near the left rear side of the washing tank structure 100. The water inlet 102 of the right washing tank 12 can be arranged near the right rear side of the washing tank structure 100. Compared with the water supply channel 106, the water inlet 102 is located at a higher position, and the filter section 20 is located at a lower position. The water entering from the water inlet 102 can flow to the filter section 20 through the water supply channel 106 under the action of gravity.

[0183] exist Figure 1 In the embodiment, the two scraping bars 86 and the bottom surface of the cleaning tank 12 form a water supply channel 106. In one embodiment, the mop 200 can rotate on the scraping bars 86. During the rotation, the mop 200 can be soaked by the clean water in the first section channel 108. The scraping bars 86 can scrape and wash the soaked mop 200. The scraped sewage or stains and other debris can flow into the filter section 20 through the second section channel 110, so that the sewage can be discharged through the filter section 20. It can be understood that in other embodiments, the water supply channel 106 can be formed not only by two scraping bars 86 and the bottom surface of the cleaning tank 12, but also by three, four or other numbers of scraping bars 86 and the bottom surface of the cleaning tank 12, which is not specifically limited here.

[0184] Optionally, combine Figure 1 and Figure 2 The end of the scraper bar 86 close to the front side of the cleaning tank structure 100 close to the filter section 20 is spaced from the edge of the filter section 20, so that the water in the cleaning tank 12 can flow into the filter part 24 faster.

[0185] When the mop 200 rotates so that the scraper 86 scrapes and washes the mop 200, the fluff 202 of the mop 200 can be located in the first channel 108, and the clean water in the first channel 108 can wet and clean the fluff 202 of the mop 200. The dirty water after cleaning can flow to the second channel 110. The second channel 110 is deeper, so that the fluff 202 of the mop 200 cannot contact the dirty water in the second channel 110, thereby avoiding secondary pollution of the mop 200 in the second channel 110.

[0186] The depth of the first channel 108 refers to the vertical distance from a point on the scraper strip 86 to the bottom of the first channel 108. The depth of the second channel 110 refers to the vertical distance from a point on the scraper strip 86 to the bottom of the second channel 110.

[0187] Optionally, the first section channel 108 may include a plurality of first sub-segment channels having different depths and connected end to end, the second section channel 110 may include a plurality of second sub-segment channels having different depths and connected end to end, the depth of the second section channel 110 may be the average depth of the second sub-segment channels, and the depth of the first section channel 108 may be the average depth of the first sub-segment channels.

[0188] It is understandable that the present invention does not specifically limit the number of scraper strips 86 in the cleaning tank 12 .

[0189] In some embodiments, the first section channel 108 includes a first end 112 and a second end 114, and the second section channel 110 includes a third end 116 and a fourth end 118, the first end 112 is connected to the water inlet 102, the second end 114 is connected to the third end 116, and the fourth end 118 is connected to the filter section 20;

[0190] The depth of the first end 112 is H1, which is selected from the range of [1, 5] mm, the depth of the second end 114 and the third end 116 is H2, which is selected from the range of [2, 8] mm, the depth of the fourth end 118 is H3, which is selected from the range of [5, 15] mm, and H1<=H2<=H3.

[0191] In this way, by determining the depth range of each end of the first section channel 108 and the second section channel 110 , it can be further ensured that the mop 200 is not likely to come into contact with the sewage in the channel.

[0192] Specifically, in one embodiment, the first end 112 is connected to the water inlet 102, the second end 114 is connected to the third end 116, and the fourth end 118 is connected to the filter section 20, so that water can be discharged into the filter section 20, and then by setting the depth H1 of the first end 112 to a range of [1,5] mm, the depth H2 of the second end 114 and the third end 116 to a range of [2,8] mm, and the depth H3 of the fourth end 118 to a range of [5,15] mm, so that H1<=H2<=H3, it is further ensured that the mop 200 is not easy to contact the sewage in the channel.

[0193] In some examples, the depth H1 of the first end 112 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or another value between 1 mm and 5 mm.

[0194] In some examples, the depth H2 of the second end 114 and the third end 116 may be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or another value between 2 mm and 8 mm.

[0195] In some examples, the depth H3 of the fourth end 118 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 another value between 5 mm and 15 mm.

[0196] In some embodiments, along the direction from the water inlet 102 to the filter section 20 , the inclination angle of the bottom surface of the first section channel 108 relative to the horizontal plane is smaller than the inclination angle of the bottom surface of the second section channel 110 relative to the horizontal plane.

[0197] In this way, the second section of the channel 110 is more inclined, which is conducive to the sewage flowing faster and flushing away the dirt.

[0198] Specifically, combined Fig.11 The inclination angle of the bottom surface of the first section channel 108 relative to the horizontal plane is smaller than the inclination angle of the bottom surface of the second section channel 110 relative to the horizontal plane. The above two inclination angles can be acute angles, thereby making the second section channel 110 more inclined, which is conducive to faster sewage flow and flushing away dirt.

[0199] A cleaning device according to an embodiment of the utility model comprises a base station, and the base station comprises the cleaning tank structure 100 according to any one of the above embodiments.

[0200] In the above-mentioned cleaning device, when the filter element 16 is in the first position, the water in the cleaning tank 12 can flow into the flow channel section 22 through the filter portion 24, and then the water in the cleaning tank 12 can be filtered. When the filter element 16 is in the second position, the filter portion 24 is located outside the filter section 20, and the flow channel portion 26 is located outside the flow channel section 22, so that the user can easily clean the drainage channel 14 through the installation port 18 to avoid the problem of stains remaining in the drainage channel 14 causing the cleaning tank structure 100 to stink.

[0201] Specifically, the base station includes a shell, and a housing space may be provided near the bottom of the shell. The cleaning tank structure 100 may be installed in the housing space, and the opening of the housing space may be connected to the external environment. The base station also includes a climbing plate, and the climbing plate may be connected to the edge of the housing space near the bottom of the base station. The cleaning robot may send the mop 200 into the cleaning tank 12 through the climbing plate. It can be understood that the cleaning tank structure 100 may be provided not only on the base station, but also on other equipment for cleaning components of other equipment.

[0202] Optionally, in one embodiment, the cleaning device may include a base station. In another embodiment, the cleaning device may include a base station and a cleaning robot.

[0203] Specifically, the cleaning robot includes a double-turntable cleaning robot (with two mops 200) and a single-turntable cleaning robot (with a single mop 200), and the rotation axis of the mop 200 is based on a body perpendicular to the cleaning robot. Fig.12In the illustrated embodiment, the cleaning tank structure 100 can be used in conjunction with a double-turntable cleaning robot. After cleaning, the cleaning robot can return to the base station and place the mop 200 in the cleaning tank 12 for cleaning. At the same time, the base station can also charge the cleaning robot, collect dust, and perform other operations. After the mop 200 of the cleaning robot is cleaned or the cleaning robot is charged, the cleaning robot can leave the base station to continue cleaning, or stay at the base station until waiting for the next cleaning instruction.
