[0033] It should be noted that, without conflict, the embodiments in this application and the technical features in the embodiments can be combined with each other. The detailed description in the specific implementation mode should be understood as an explanatory illustration of the purpose of this application and should not be regarded as an improper limitation of this application.

[0034] The following further describes this application in detail with reference to the drawings and specific embodiments. The descriptions such as "first" and "second" in the embodiments of this application are only for the purpose of description and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] An embodiment of this application provides a cleaning device. Please refer to Figures 1 to 7 , the cleaning device 100 includes a housing 1, a water supply member and a mop plate 2. The housing 1 includes a water replenishing hole 1b. The water supply member is arranged on the housing 1 and is used to supply water to the water replenishing hole 1b. The mop plate 2 is movably arranged at the bottom of the housing 1. The mop plate 2 is provided with a mop cloth. The mop plate 2 can change between a second position A and a first position B relative to the housing 1. At least part of the area of the mop plate 2 is provided with a hollow area 2a. When the mop plate 2 is in the first position B, the water replenishing hole 1b and the hollow area 2a at least partially overlap on the projection plane to replenish water to the hollow area 2a. When the mop plate 2 is in the second position A, the water replenishing hole 1b and the hollow area 2a do not overlap on the projection plane.

[0036] It can be understood that the projection plane can be an imaginary plane where the object is projected along the top-bottom direction.

[0037] It should be noted that the first position B and the second position A can be distinguished by the projection area on the projection plane. For example, when the drag plate 2 is in the second position A, the drag plate 2 and the housing 1 do not overlap at least partially on the projection plane. When the drag plate 2 is in the first position B, the drag plate 2 and the housing 1 overlap on the projection plane. In some embodiments, the drag plate 2 may overlap with the housing 1 on the projection plane both in the state of the first position B and in the state of the second position A, but when in the second position A, it is closer to the edge of the housing 1 than in the first position B; or, the drag plate 2 may not overlap with the housing 1 on the projection plane both in the state of the first position B and in the state of the second position A, but the area of the non-overlapping region of the drag plate 2 in the first position B is smaller than the area of the non-overlapping region of the drag plate 2 in the second position A.

[0038] In the cleaning device 100 provided in the present application, the drag plate 2 is movably arranged at the bottom of the housing 1. In this way, on the one hand, it can drive the mop to move to places that the cleaning device 100 cannot directly reach, so as to improve the cleaning coverage rate; on the other hand, for hard-to-reach corner areas, such as the edges of walls, etc., the movable mop can clean dust and stains more effectively, improving the cleaning effect; on the other hand, since the corners and hard-to-reach areas are cleaned, the manual cleaning by the user can be reduced, and the user experience is good. The water supply member provided in the present application can supply water to the water replenishing hole 1b. The drag plate 2 has a second position A and a first position B. When the drag plate 2 is in the first position B, the water replenishing hole 1b and the hollow area 2a overlap on the projection plane, and the water flowing out of the water replenishing hole 1b can replenish water to the mop through the hollow area 2a. When the drag plate 2 is in the second position A, since the water replenishing hole 1b and the hollow area 2a do not overlap on the projection plane, the water flowing out of the water replenishing hole 1b cannot replenish water to the mop and / or the drag plate 2 through the hollow area 2a. That is to say, when the drag plate 2 moves to the first position B, it can be replenished with water through the water replenishing hole 1b, and when the drag plate 2 is in the second position A, the water replenishing hole 1b cannot replenish water to the mop through the hollow area 2a. In this way, on the one hand, it reduces the excessive wetness of the ground caused by too much water on the mop, and then it can reduce the swelling, foaming and deformation of the ground such as wooden floors, and even reduce the growth of bacteria and molds, improving the indoor air quality; on the other hand, it can reduce the obvious water stains or water marks left due to too much water on the mop, improving the cleaning effect.

[0039] It should be noted that the top refers to the direction towards the ceiling, and the bottom is opposite to the top.

[0040] In one embodiment, please refer to Figures 1 to 7 , the drag plate 2 has a transition position between the second position A and the first position B. When the drag plate 2 is in the first position B, when the drag plate 2 is in the first position B, when the drag plate 2 is in the transition position, the water replenishing hole 1b and the hollow area 2a do not overlap on the projection plane.

[0041] That is to say, when the platen 2 is in the transition position, the water replenishing hole 1b is also offset from the hollow area 2a, which means that the water replenishing hole 1b cannot replenish water to the mop through the hollow area 2a. In this way, the water replenishing hole 1b cannot replenish water to the mop in both the second position A and the transition position, so as to further reduce the amount of water on the mop, and then the generation of water stains can be reduced.

[0042] In one embodiment, compared with the first position B, the overlapping area of the platen 2 and the housing 1 on the projection plane is smaller at the second position A. That is to say, when the platen 2 is at the second position A, the part extending out of the housing 1 is more. In this way, relatively narrow spaces and the edges of corners can be cleaned, and the cleaning effect is better.

[0043] In one embodiment, please refer to Figure 3 , the hollow area 2a of the platen 2 in the first position B and the hollow area 2a of the platen 2 in the second position A at least partially overlap on the projection plane.

[0044] In this way, the area of the hollow area 2a can be increased, so that the amount of replenished water becomes larger and the water replenishing efficiency is improved.

[0045] In one embodiment, please refer to Figure 3 , in the state where the platen 2 is in the first position B, a water replenishing hole 1b is provided on the area of the housing 1 corresponding to the non-overlapping area in the hollow area 2a.

[0046] In this way, by arranging the water replenishing hole 1b on the area of the housing 1 corresponding to the non-overlapping area in the hollow area 2a in the state where the platen 2 is in the first position B, the water replenishing hole 1b can replenish water to the mop only through the non-overlapping area in the hollow area 2a when the platen 2 is in the first position B, and the situation that the water replenishing hole 1b replenishes water to the mop under the hollow area 2a in the state where the platen 2 is in the second position A can be reduced, and the working stability is good.

[0047] In one embodiment, please refer to Figures 1 to 3 , the platen 2 includes a first central portion 21, a first connecting portion 22, a first hollow portion 23 and a second connecting portion 24. The first connecting portion 22 is wound around the outer periphery of the first central portion 21. The first hollow portion 23 is located between the first connecting portion 22 and the second connecting portion 24 along the radial direction of the first central portion 21. The first hollow portion 23 forms a hollow area 2a, and the mop is connected to the first connecting portion 22 and the second connecting portion 24.

[0048] Exemplarily, the shape of the drag plate 2 is not limited, for example, the projection shape along the top and bottom direction can be circular or rectangular, etc. The first central portion 21 can be the central area of the drag plate 2, the first connecting portion 22 is arranged around the outer periphery of the first central portion 21, the first hollow portion 23 can be arranged around the outer periphery of the first connecting portion 22, the second connecting portion 24 can be arranged around the outer periphery of the first hollow portion 23, the first hollow portion 23 is formed with a hollow area 2a, and the mop is connected to the first connecting portion 22 and the second connecting portion 24, so that the connection strength between the mop and the drag plate 2 can be increased, the situation where the mop falls off can be reduced, and the working stability is good.

[0049] The first hollow portion 23 of the carriage 2 at the first position B and the first hollow portion 23 of the carriage 2 at the second position A at least partially overlap on the projection plane.

[0050] Exemplarily, on the projection plane, the projection area of the first hollow portion 23 when the drag plate 2 is in the second position A is the first projection area, and the projection area of the first hollow portion 23 when the drag plate 2 is in the first position B is the second projection area, the first projection area partially overlaps with the second projection area, and the water replenishment hole 1b is located at a position corresponding to the hollow area 2a in the non-overlapping second projection area.

[0051] The projection shape of the first hollow portion 23 along the top and bottom directions can be annular, that is, the shape of the first projection area and the shape of the second projection area can be annular. The first projection area and the second projection area partially intersect and overlap, the projection area corresponding to the first connection part 22 when the carriage 2 is in the second position A and the projection area corresponding to the first connection part 22 when the carriage 2 is in the first position B also partially intersect and overlap, and the projection area corresponding to the second connection part 24 when the carriage 2 is in the second position A passes through the projection area corresponding to the first central part 21 when the carriage 2 is in the first position B. Therefore, when the carriage 2 is in the first position B, the water replenishment hole 1b can be set on the housing 1 area corresponding to the non-overlapping area in the hollow area 2a, so that the water replenishment hole 1b can be aligned with its hollow area 2a when the carriage 2 is in the first position B, and staggered with its hollow area 2a when the carriage 2 is in the second position A, so that the setting position of the water replenishment hole 1b is more flexible.

[0052] In one embodiment, please refer to Figure 7 , the hollow area 2a of the carriage 2 at the first position B and the hollow area 2a of the carriage 2 at the second position A do not overlap on the projection surface.

[0053] In this way, interference can be reduced and water replenishment can be stable.

[0054] In one embodiment, please refer to Figure 7 When the carriage 2 is in the first position B, a water replenishment hole 1b is provided on the area of the shell 1 corresponding to the hollow area 2a.

[0055] In this way, the water replenishment hole 1b can be set on the area of the shell 1 corresponding to the hollow area 2a in the first position B state. In this way, the water replenishment hole 1b can replenish water to the mop through the hollow area 2a only when the drag plate 2 is in the first position B, which can reduce the situation where the water replenishment hole 1b replenishes water to the mop under the hollow area 2a in the second position A, and the working stability is good.

[0056] In one embodiment, please refer to Figures 5 to 7 The drag plate 2 includes a second central portion 25, a supporting portion 26, a second hollow portion 27 and a third connecting portion 28. The second hollow portion 27 is arranged around the outer periphery of the second central portion 25. The supporting portion 26 is located between the second hollow portion 27 and the third connecting portion 28 along the radial direction of the second central portion 25. The second hollow portion 27 is formed with a hollow area 2a. The mop is connected to the third connecting portion 28 and supported by the supporting portion 26.

[0057] Exemplarily, the shape of the drag plate 2 is not limited, for example, the projection shape along the top and bottom direction can be circular or rectangular, etc. The second central portion 25 can be the central area of the drag plate 2, the second hollow portion 27 is arranged around the outer periphery of the second central portion 25, the support portion 26 can be arranged around the outer periphery of the second hollow portion 27, the third connecting portion 28 can be arranged around the outer periphery of the support portion 26, the second hollow portion 27 can be formed with a hollow area 2a, and the mop is connected to the third connecting portion 28 and supported on the support portion 26, so as to increase the support of the drag plate 2 to the mop, and the mopping effect is good.

[0058] The second hollow portion 27 of the carriage 2 at the first position B and the second hollow portion 27 of the carriage 2 at the second position A do not overlap on the projection plane.

[0059] Exemplarily, on the projection plane, the projection area of the second hollow portion 27 when the drag plate 2 is in the second position A is the third projection area, and the projection area of the second hollow portion 27 when the drag plate 2 is in the first position B is the fourth projection area. The third projection area does not overlap with the fourth projection area, and the water replenishment hole 1b is located at a position in the fourth projection area corresponding to the hollow area 2a.

[0060] The projection shape of the second hollow portion 27 along the top and bottom directions can be annular, that is, the shape of the third projection area and the shape of the fourth projection area can be annular, and the third projection area and the fourth projection area are staggered, that is, the third projection area and the fourth projection area have no overlapping part. Therefore, the water replenishment hole 1b can be set at a position on the shell 1 having a corresponding hollow area 2a in the fourth projection area, so that the water replenishment hole 1b can be aligned with the hollow area 2a when the carriage 2 is in the first position B, and staggered with the hollow area 2a when the carriage 2 is in the second position A, so that the setting position is more flexible.

[0061] For example, in one embodiment, please refer to Figure 1, Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , the hollow area 2a has a plurality of them. For example, the number of the hollow areas 2a can be 8, and the 8 hollow areas 2a are arranged at intervals in the circumferential direction in the hollow area. In this way, when the mop plate 2 rotates around its center at the corresponding position, the water replenishing holes 1b replenish water to the mop under the plurality of hollow areas 2a, improving the uniformity of water replenishment to the mop.

[0062] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , an anti-collision rib 3 is provided on the outer periphery of the mop plate 2. Exemplarily, the anti-collision rib 3 can be wound around the outer periphery of the second connecting portion 24 or the third connecting portion 28. In this way, the damage to the mop plate 2 when colliding with obstacles such as walls or seats can be reduced, and the service life of the cleaning device 100 can be improved.

[0063] Exemplarily, in one embodiment, the anti-collision rib 3 can be made of rubber or silica gel and other materials.

[0064] In one embodiment, the mop plate 2 is detachably connected to the housing 1. Exemplarily, the mop plate 2 and the housing 1 can be magnetically connected or snap-connected. In this way, when it is necessary to replace the mop, the mop plate 2, perform maintenance or remove foreign objects such as hair, the mop plate 2 can be disassembled and then processed, with high efficiency.

[0065] In one embodiment, please refer to Figure 4 , the housing 1 is formed with a guiding groove 1a, and the guiding groove 1a includes a swing-out portion 1a1, a transition portion 1a2 and a retraction portion 1a3. The swing-out portion 1a1 can be located at the edge of the housing 1, the retraction portion 1a3 can be located on the side of the swing-out portion 1a1 facing the center of the housing 1, the transition portion 1a2 is bent to connect the swing-out portion 1a1 and the retraction portion 1a3, the swing-out portion 1a1 corresponds to the second position A, the transition portion 1a2 corresponds to the transition position, and the retraction portion 1a3 corresponds to the first position B.

[0066] In one embodiment, the housing 1 is formed with a water storage cavity. The cleaning device 100 includes a water replenishing controller and a first sensor. The water supply member is connected to the water storage cavity and the water replenishing holes 1b. The first sensor is used to detect the position of the mop plate 2. The water replenishing controller is respectively communicatively connected to the water supply member and the first sensor. In the state where the mop plate 2 is in the first position B, the water replenishing controller controls the water supply member to supply water to the water replenishing holes 1b.

[0067] Exemplarily, the first sensor can detect whether the mop plate 2 is in the first position B, the second position A, and the transition position. The water replenishment controller can communicate with the water supply component and the first sensor through a local area network, Bluetooth, WIFI, or network cable, etc. When the first sensor detects that the mop plate 2 is in the first position B, it can send an instruction to the water replenishment controller. After receiving the instruction, the water replenishment controller can send a water replenishment instruction to the water supply component. After receiving the water replenishment instruction, the water supply component is driven to convey the water in the water storage cavity to the water replenishment hole 1b to replenish the mop under the hollow area 2a. It has a high degree of intelligence, good cleaning effect, and good user experience.

[0068] Exemplarily, in one embodiment, the water supply component can be a water pump. For example, it can be a peristaltic pump, which can supply water to the water replenishment hole 1b slowly and quantitatively.

[0069] In one embodiment, the cleaning device 100 includes a swinging device and a second sensor. The second sensor and the swinging device are respectively communicatively connected to the water replenishment controller. The second sensor is used to obtain the traveling distance of the cleaning device 100, and the swinging device is used to control the switching of the mop plate 2 between the first position B and the second position A.

[0070] Exemplarily, the second sensor can obtain the traveling distance between the current position of the cleaning device 100 and the last water replenishment position, and the swinging device can control the switching of the mop plate 2 between the first position B and the second position A. The water replenishment controller can communicate with the second sensor and the swinging device through a local area network, Bluetooth, WIFI, or network cable, etc. In this way, when it is determined that the cleaning device 100 is in the state of walking away from the wall, when the traveling distance obtained by the second sensor reaches the set distance, it can send an instruction to the water replenishment controller. After receiving the instruction, the water replenishment controller sends an instruction to the swinging device, and the swinging device can then control the mop plate 2 to switch from the second position A to the first position B. When the first sensor detects that the mop plate 2 is in the first position B, it can send an instruction to the water replenishment controller. After receiving the instruction, the water replenishment controller can send a water replenishment instruction to the water supply component. After receiving the water replenishment instruction, the water supply component is driven to convey the water in the water storage cavity to the water replenishment hole 1b to replenish the mop under the hollow area 2a.

[0071] In one embodiment, multiple set water volumes are set, and a mapping relationship is established between the set water volumes and the set distances. When the cleaning device 100 walks to the set distance, the mop and / or the mop plate is replenished with the corresponding set water volume.

[0072] Thirty set water volumes can be set. The thirty set water volumes are divided into levels 1 to 30, and the corresponding set travel distances are from 230 cm to 85 cm, with a step of 5 cm. Specifically, the 1st level set water volume corresponds to a set travel distance of 230 cm, the 7th level set water volume can correspond to a set travel distance of 200 cm, the 13th level set water volume can correspond to a set travel distance of 170 cm, the 23rd level set water volume can correspond to a set travel distance of 120 cm, and the 30th level set water volume can correspond to a set travel distance of 85 cm. The 1st level set water volume can be defined as an ultra-small water volume, the 7th level set water volume as a small water volume, the 13th level set water volume as a medium water volume, and the 23rd level set water volume as a large water volume. The user can select according to needs, or the cleaning device 100 can make an intelligent selection according to the dirt level of the ground to be cleaned.

[0073] Taking the 1st level set water volume and a set travel distance of 230 cm as an example, when it is determined that the cleaning device 100 is in the state of walking away from the wall, every time the cleaning device 100 walks to 230 cm, the 1st level set water volume is replenished to the mop; for another example, taking the 7th level set water volume and a set travel distance of 200 cm as an example, when it is determined that the cleaning device 100 is in the state of walking away from the wall, every time the cleaning device 100 walks to 200 cm, the 7th level set water volume is replenished to the mop.

[0074] The set water volume of each level can be the same, that is, the set water volumes corresponding to different set travel distances are the same. For example, the replenishing water volume when walking to 200 cm is the same as the replenishing water volume when walking to 230 cm. In some other embodiments, the set water volume of each level can be different. For example, the replenishing water volume when walking to 200 cm is different from the replenishing water volume when walking to 230 cm.

[0075] It should be noted that the state of walking away from the wall means that the mopping and sweeping environment is relatively spacious and there are few obstacles.

[0076] In one embodiment, the cleaning device 100 has a state of walking along the wall. When it is determined that the cleaning device 100 is in the state of walking along the wall, when the mopping plate 2 is in the first position B, the first walking distance between the current position of the cleaning device 100 and the previous water replenishing position is obtained; based on the ratio between the first walking distance and the set travel distance, the water supply member is controlled; wherein, the water replenishing position is the position where the cleaning device 100 is located when the water supply member starts to replenish water to the mop.

[0077] It should be noted that the state of walking along the wall does not only refer to walking along the wall, but can also be along an object with a long edge such as a sofa. When the cleaning device 100 is in the state of walking along the wall, the mopping plate 2 may avoid some obstacles such as corners and table legs, causing the mopping plate 2 to switch from the second position A to the first position B.

[0078] Here, after it is determined that the cleaning device 100 is in the state of walking along the wall, when the mop plate 2 is in the first position B, the first walking distance between the current position of the cleaning device 100 and the previous water replenishment position can be obtained through the second sensor, and then the ratio between the first walking distance and the selected set distance is calculated as the basis for controlling the opening of the water supply member.

[0079] In one embodiment, if the ratio is less than the set duration, water is not replenished to the mop plate 2 and / or the mop cloth; if the ratio is not less than the set duration, water is replenished to the mop plate 2 and / or the mop cloth.

[0080] Here, when the mop plate 2 is in the first position B, if the ratio is less than the set duration, it means that the first walking distance is short and the distance from the previous water replenishment position is close. If the mop cloth is replenished with water, the amount of water on the mop cloth will be too much; if the ratio is not less than the set duration, it means that the first walking distance is long and the distance from the previous water replenishment position is far. The water supply member can be opened to supply water through the water replenishment hole 1b, and then the mop cloth is replenished with water to reduce the situation of dry mopping.

[0081] In one embodiment, the set duration can be between 1 s and 2 s. Exemplarily, the set duration can be 1 s, 1.5 s, 2 s, etc. Taking 1 s as an example, when the selected set water volume is 23 levels and the set distance is 120 cm, if the first walking distance is 200 cm when the mop plate 2 is in the first position B, then the ratio is 1.6, that is, greater than 1 s, and the water replenishment controller will control the water supply member to open to replenish the mop cloth with water; if the first walking distance is 60 cm when the mop plate 2 is in the first position B, then the ratio is 0.5, that is, less than 1 s, and the water supply member is controlled to close without replenishing the mop cloth with water.

[0082] In one embodiment, the water replenishment duration can be determined according to the ratio between the first walking distance and the selected set distance. For example, when the selected set water volume is 23 levels and the set distance is 120 cm, if the first walking distance is 200 cm when the mop plate 2 is in the first position B, then the ratio is 1.6, that is, greater than 1 s, and the water replenishment controller will control the water supply member to open to replenish the mop cloth with 23 levels of set water volume, and the water replenishment duration is 1.6 s.

[0083] In one embodiment, when the mop plate 2 is in the second position A, the second walking distance between the current position of the cleaning device 100 and the previous water replenishment position is determined; if the second walking distance is not less than the set upper limit distance, the mop plate 2 is controlled to switch from the second position A to the first position B, and the water supply member is controlled to open.

[0084] It can be understood that when the cleaning device 100 is in the state of walking along the wall, when there is no obstacle, the mop plate 2 will not be passively switched to the first position B. That is to say, it will only actively retract to the first position B after encountering an obstacle.

[0085] In this way, when the platen 2 is in the second position A, by determining the second travel distance between the current position of the cleaning device 100 and the previous water replenishment position, if the second travel distance is greater than or equal to the set upper limit distance, the platen 2 can be controlled to switch from the second position A to the first position B through the swinging device, and the water supply member can be controlled to open by the water replenishment controller to supply water to the water replenishment hole 1b, and then replenish water to the mop, reducing the situation of dry mopping caused by water shortage of the mop and improving the cleaning effect.

[0086] Exemplarily, in one embodiment, the set upper limit distance can be 10 m. For example, when the distance along the wall is 20 m, by setting the set upper limit distance of 10 m, when the second travel distance reaches 10 m, the platen 2 can be controlled to switch to the first position B, and the water supply member can be controlled to replenish water to the mop.

[0087] In one embodiment, when the cleaning device 100 is not in a trapped state, for complex scenarios such as corners or the presence of chair legs, at this time, the logic in the wall-following walking state can be followed, and it can be judged by the ratio of the cumulative travel distance to the set distance. If the ratio is less than the set duration, the water supply member is controlled to close; if the ratio is not less than the set duration, the water supply member is controlled to open. That is to say, when the cleaning device 100 actively avoids and the platen 2 switches to the first position B, if the ratio of this section of the first travel distance to the set distance is less than the set duration, the water supply member is controlled to close without replenishing water, but this section of the first travel distance will be recorded and added to the next water replenishment judgment.

[0088] It can be understood that the trapped state can refer to a closed space with boundaries, where there are obstacles such as corners, desks, and chairs in the closed space, causing the platen 2 to repeatedly switch to the first position B.

[0089] In one embodiment, the cleaning device 100 has a trapped state. When it is determined that the cleaning device 100 is in the trapped state, the water supply member is controlled to close.

[0090] In this way, when it is determined that the cleaning device 100 is in the trapped state, even if the ratio of the cumulative travel distance to the set distance is greater than the set duration, in order to reduce the situation of excessive water stains caused by repeated water replenishment and mopping in the trapped space, the water supply member can be controlled to close by the water replenishment controller, and then water replenishment can be carried out after the cleaning device 100 gets out of the trapped state.

[0091] In one embodiment, when the size of the walking space of the cleaning device 100 is not greater than the set size, it is determined that the cleaning device 100 is in the trapped state; wherein, the set size is between 1.05 times and 1.1 times the floor area of the cleaning device 100.

[0092] Exemplarily, the set size can be 1.05 times, 1.06 times, 1.07 times, 1.08 times, 1.09 times, 1.1 times, etc. of the floor area occupied by the cleaning device. The shape of the walking space is not limited. For example, in the projection along the top-bottom direction, the walking space can be circular, triangular, rectangular or irregular. In some embodiments, the head of the walking space along the top-bottom direction can be a figure with a certain opening, but the size of the opening is smaller than the diameter of the cleaning device 100. Thus, when the size of the walking space of the cleaning device 100 is less than or equal to the set size, it can be determined that the cleaning device 100 is in a trapped state. At this time, the water supply pipe can be controlled to close by the water replenishment controller, reducing the situation of excessive water stains caused by repeated water replenishment and mopping in the trapped space.

[0093] Exemplarily, in one embodiment, the cleaning device 100 can be provided with a camera, a lidar or other sensors, capable of perceiving the surroundings to determine whether the cleaning device 100 is in a state of walking away from the wall, walking along the wall and a trapped state.

[0094] As described above, it is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. All any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present application are included in the protection scope of the present application.
