[0006] In view of this, the embodiments of this application aim to provide a cleaning device and control method with better cleaning effect.

[0007] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0008] One embodiment of this application discloses a cleaning device, including:

[0009] The casing, including the water inlet hole;

[0010] A sliding plate is movably disposed at the bottom of the housing, the sliding plate being able to change between a first position and a second position relative to the housing, and at least a portion of the sliding plate is provided with a hollow area;

[0013] In one embodiment, the slide has a transition position between the second position and the first position, and when the slide is in the transition position, the water inlet hole and the hollow area do not overlap on the projection surface.

[0014] In one embodiment, the second position has a smaller overlap area between the slide and the housing on the projection plane compared to the first position.

The first connecting portion is disposed around the outer periphery of the first central portion. The first hollow portion is located between the first connecting portion and the second connecting portion in the radial direction of the first central portion. The first hollow portion forms the hollow area. The mop is connected to the first connecting portion and the second connecting portion. The first hollow portion of the slide at the first position and the first hollow portion of the slide at the second position at least partially overlap on the projection surface.

[0018] In one embodiment, the hollowed-out area of ​​the slide plate in the first position and the hollowed-out area of ​​the slide plate in the second position do not overlap on the projection surface.

[0019] In one embodiment, when the slide is in the first position, the water inlet hole is provided on the housing area corresponding to the hollow area.

[0020] In one embodiment, the slide includes a second central portion, a support portion, a second hollow portion, and a third connecting portion. The second hollow portion is disposed around the outer periphery of the second central portion. The support portion is located between the second hollow portion and the third connecting portion in the radial direction of the second central portion. The second hollow portion forms the hollow area. The mop is connected to the third connecting portion and supported by the support portion. The second hollow portion of the slide in the first position and the second hollow portion of the slide in the second position do not overlap on the projection plane.

[0021] In one embodiment, anti-collision ribs are provided on the outer periphery of the slide.

[0022] In one embodiment, the slide plate is detachably connected to the housing.

[0023] In one embodiment, the housing has a water storage cavity, and the cleaning device includes a water supply component, a water replenishment controller, and a first sensor. The water supply component is connected to the water storage cavity and the water replenishment hole. The first sensor is used to detect the position of the slide. The water replenishment controller is communicatively connected to the water supply component and the first sensor. When the slide is in the first position, the water replenishment controller controls the water supply component to supply water to the water replenishment hole.

[0024] In one embodiment, the cleaning device includes a swing device and a second sensor. The second sensor and the swing device are respectively communicatively connected to the water replenishment controller. The second sensor is used to acquire the walking distance of the cleaning device, and the swing device is used to control the mop to switch between the first position and the second position.

[0025] Another aspect of this application discloses a control method, including the cleaning device in any of the above embodiments, wherein the cleaning device includes a water supply component, and the control method includes:

[0026] Once the mop is determined to be in the first position, the water supply component is controlled to supply water to the water inlet to replenish the mop and / or the mop cloth.

[0027] In one embodiment, the cleaning device has a wall-moving state, and the control method includes:

[0028] When the cleaning device is determined to be in a state of walking away from the wall, and the mop is in the first position, when the cleaning device has traveled a set distance, the water supply component is turned on to replenish water to the mop and / or the mop cloth.

[0029] In one embodiment, the control method includes:

[0030] Multiple preset water volumes are set, and a mapping relationship is established between the preset water volumes and the preset distances. When the cleaning equipment travels to the preset distance, the mop and / or the mop plate are replenished with water corresponding to the preset water volumes.

[0031] In one embodiment, the cleaning device has a wall-walking state, and the control method includes:

[0032] Determine that the cleaning equipment is in a wall-walking state. When the mop is in the first position, obtain the first walking distance between the current position of the cleaning equipment and the last water replenishment position.

[0033] The water supply component is controlled based on the ratio between the first travel distance and the set distance; wherein, the water replenishment position is the position of the cleaning equipment when the water supply component replenishes water to the mop.

[0034] In one embodiment, the control method includes:

[0035] If the ratio is less than the set time, no water will be added to the mop and / or the mop cloth;

[0036] If the ratio is not less than the set duration, then water is added to the mop and / or the mop cloth.

[0037] In one embodiment, the control method includes:

[0038] When the tray is in the second position, determine the second travel distance between the current position of the cleaning equipment and the last water replenishment position;

[0039] If the second travel distance is not less than the set upper limit distance, then control the slide to switch from the second position to the first position, and control the water supply component to turn on.

[0040] In one embodiment, the cleaning equipment is in a trapped state, and the control method includes:

[0041] Once it is determined that the cleaning equipment is in the trapped state, the water supply component is shut off.

[0042] In one embodiment, when the size of the walking space of the cleaning equipment is not greater than a set size, the cleaning equipment is determined to be in the trapped state.

[0043] The cleaning device provided in this application has a movable mop plate located at the bottom of the housing. This allows the mop plate to be moved to places that the cleaning device cannot directly reach, thereby improving cleaning coverage. On the other hand, for hard-to-reach corner areas, such as wall edges, the movable mop plate 2 can more effectively clean dust and stains, improving the cleaning effect. Furthermore, since corners and hard-to-reach areas are cleaned, manual cleaning by the user can be reduced, resulting in a better user experience. The mop has a second position and a first position. In the first position, the water inlet and the perforated area overlap on the projection surface, allowing water from the water inlet to replenish the mop cloth through the perforated area. However, in the second position, since the water inlet and the perforated area do not overlap on the projection surface, water from the water inlet cannot replenish the mop cloth and / or the mop itself through the perforated area. In other words, the mop can only replenish water through the water inlet when it is moved to the first position. When the mop is in the second position, the water inlet cannot replenish water to the mop cloth through the perforated area. This reduces the amount of water on the mop cloth, which can lead to excessive wetting of the floor and thus reduce the expansion, bubbling, and deformation of floors such as wooden floors. It can also reduce the growth of bacteria and mold, improving indoor air quality. Furthermore, it reduces the amount of water on the mop cloth, which can leave obvious water stains or marks, improving cleaning effectiveness. Attached Figure Description

[0051] Figure 8 is a flowchart illustrating a control method provided in another embodiment of this application. Detailed Implementation

[0052] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0053] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] This application provides a cleaning device. Referring to Figures 1 to 7, the cleaning device 100 includes a housing 1 and a tray 2. The housing 1 includes a water inlet hole 1b. The tray 2 is movably disposed at the bottom of the housing 1, and the tray 2 can change between a first position B and a second position A relative to the housing 1. At least a portion of the tray 2 has a perforated area 2a. When the tray 2 is in the first position B, the water inlet hole 1b and the perforated area 2a at least partially overlap on the projection plane to replenish water to the perforated area 2a. When the tray 2 is in the second position A, the water inlet hole 1b and the perforated area 2a do not overlap on the projection plane.

[0055] It is understandable that the projection plane can be an imaginary plane on which the object is projected along the top-bottom direction.

[0056] 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 slide 2 is in the second position A, the slide 2 and the housing 1 do not overlap at least partially on the projection plane; when the slide 2 is in the first position B, the slide 2 and the housing 1 overlap on the projection plane. In some embodiments, the slide 2 can overlap with the housing 1 on the projection plane in both the first position B and the second position A, except that in the second position A, the slide 2 is closer to the edge of the housing 1 relative to the first position B; or, the slide 2 can not overlap with the housing 1 on the projection plane in both the first position B and the second position A, except that the area of ​​the non-overlapping region of the slide 2 in the first position B is smaller than the area of ​​the non-overlapping region of the slide 2 in the second position A.

[0057] For example, a mop can be installed on the mop plate 2.

[0058] The cleaning device 100 provided in this application has a movable mop 2 located at the bottom of the housing 1. This allows the mop 2 to be moved to places that the cleaning device 100 cannot directly reach, thereby improving cleaning coverage. On the other hand, for hard-to-reach corner areas, such as wall edges, the movable mop 2 can more effectively clean dust and stains, improving the cleaning effect. Furthermore, since corners and hard-to-reach areas are cleaned, manual cleaning by the user can be reduced, resulting in a better user experience. The mop 2 has a second position A and a first position B. When the mop 2 is in the first position B, the water inlet 1b overlaps with the perforated area 2a on the projection surface, and the water flowing out of the water inlet 1b can replenish the mop cloth through the perforated area 2a. However, when the mop 2 is in the second position A, since the water inlet 1b and the perforated area 2a do not overlap on the projection surface, the water flowing out of the water inlet 1b cannot replenish the mop cloth and / or the mop 2 through the perforated area 2a. In other words, the mop 2 can only replenish water through the water inlet 1b when it is moved to the first position B. When the mop 2 is in the second position A, the water inlet 1b cannot replenish the mop cloth through the perforated area 2a. This reduces the amount of water on the mop cloth, which can lead to excessive wetting of the floor and thus reduce the expansion, bubbling, and deformation of floors such as wooden floors. It can also reduce the growth of bacteria and mold, improving indoor air quality. Furthermore, it reduces the amount of water on the mop cloth, which can leave obvious water stains or marks, improving cleaning effectiveness.

[0059] It should be noted that "top" refers to the direction facing the ceiling, while "bottom" is the opposite of "top".

[0060] In one embodiment, the slide plate 2 has a transition position between the second position A and the first position B. When the slide plate 2 is in the transition position, the water inlet hole 1b and the hollow area 2a do not overlap on the projection surface.

[0061] In other words, when the mop plate 2 is in the transition position, the water inlet 1b will also be offset from the perforated area 2a, meaning that the water inlet 1b cannot replenish water to the mop through the perforated area 2a. Thus, the water inlet 1b cannot replenish water to the mop in both the second position A and the transition position, thereby further reducing the amount of water on the mop and consequently reducing the formation of water stains.

[0062] In one embodiment, the overlap area between the sliding plate 2 and the housing 1 on the projection plane is smaller in the second position A compared to the first position B. That is, in the second position A, the sliding plate 2 extends more out of the housing 1, which allows for cleaning of narrower spaces and corner edges, resulting in better cleaning performance.

[0063] In one embodiment, please refer to FIG3, the cutout area 2a of the slide plate 2 at the first position B and the cutout area 2a of the slide plate 2 at the second position A at least partially overlap on the projection plane.

[0064] This increases the area of ​​the hollowed-out area 2a, resulting in a larger water replenishment volume and improved water replenishment efficiency.

[0065] In one embodiment, please refer to FIG3. When the slide plate 2 is in the first position B, a water replenishment hole 1b is provided on the housing 1 area corresponding to the non-overlapping area in the hollow area 2a.

[0066] In this way, by setting the water replenishment hole 1b on the housing 1 area corresponding to the non-overlapping area in the hollow area 2a in the first position B state, the water replenishment hole 1b can replenish water to the mop only through the non-overlapping area in the hollow area 2a when the drag plate 2 is in the first position B state. This reduces the occurrence of the water replenishment hole 1b replenishing water to the mop under the hollow area 2a in the second position A state, resulting in good working stability.

[0067] In one embodiment, referring to Figures 1 to 3, the slide plate 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 disposed 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 in the radial direction of the first central portion 21. The first hollow portion 23 forms a hollow area 2a. The mop is connected to the first connecting portion 22 and the second connecting portion 24.

[0068] For example, the shape of the slide plate 2 is not limited; for instance, the projected 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 slide 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, and the second connecting portion 24 can be arranged around the outer periphery of the first hollow portion 23. The first hollow portion 23 forms a hollow area 2a. The mop is connected to the first connecting portion 22 and the second connecting portion 24. In this way, the connection strength between the mop and the slide plate 2 can be increased, the occurrence of the mop falling off can be reduced, and the working stability can be improved.

[0069] The first hollow portion 23 of the slide plate 2 in the first position B and the first hollow portion 23 of the slide plate 2 in the second position A at least partially overlap on the projection surface. For example, on the projection surface, the projection area of ​​the first hollow portion 23 in the outward position A of the slide plate 2 is the first projection area, and the projection area of ​​the first hollow portion 23 in the retracted position B of the slide plate 2 is the second projection area. The first projection area and the second projection area at least partially overlap, and the water inlet hole 1b is located in the non-overlapping second projection area corresponding to the position of the hollow area 2a. The projection shape of the first hollow portion 23 along the top-bottom direction can be annular. The first connecting part 22 partially intersects and overlaps with the first connecting part 22 when the slide plate 2 is in the second position A and the first connecting part 22 when the slide plate 2 is in the first position B on the projection surface. On the projection surface, the projection area of ​​the second connecting part 24 when the slide plate 2 is in the second position A passes through the projection area of ​​the first center part 21 when the slide plate 2 is in the first position B. Therefore, when the slide plate 2 is in the first position B, the water inlet hole 1b can be set on the housing 1 area corresponding to the non-overlapping area in the hollow area 2a. In this way, the water inlet hole 1b can be aligned with the hollow area 2a when the slide plate 2 is in the first position B, and offset from the hollow area 2a when the slide plate 2 is in the second position A, making the setting position of the water inlet hole 1b more flexible.

[0070] In one embodiment, please refer to FIG7, the cutout area 2a of the slide plate 2 at the first position B and the cutout area 2a of the slide plate 2 at the second position A do not overlap on the projection plane.

[0071] This reduces interference and stabilizes water replenishment.

[0072] In one embodiment, please refer to Figure 7. When the slide plate 2 is in the first position B, a water replenishment hole 1b is provided on the housing 1 area corresponding to the hollow area 2a.

[0073] In this way, the water replenishment hole 1b can be set on the housing 1 area 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 only when the mop plate 2 is in the first position B through the hollow area 2a. This 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 state, and improves the working stability.

[0074] In one embodiment, referring to Figures 5 to 7, the slide plate 2 includes a second central portion 25, a support portion 26, a second hollow portion 27, and a third connecting portion 28. The second hollow portion 27 is disposed around the outer periphery of the second central portion 25. The support portion 26 is located between the second hollow portion 27 and the third connecting portion 28 in the radial direction of the second central portion 25. The second hollow portion 27 forms a hollow area 2a. The slide cloth is connected to the third connecting portion 28 and supported by the support portion 26.

[0075] For example, the shape of the mop 2 is not limited; for instance, the projected 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 mop 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, and the third connecting portion 28 can be arranged around the outer periphery of the support portion 26. The second hollow portion 27 can form a hollow area 2a. The mop is connected to the third connecting portion 28 and supported by the support portion 26 to increase the support of the mop 2 on the mop, resulting in a better mopping effect.

[0076] The second hollowed-out portion 27 of the slide plate 2 in the first position B and the second hollowed-out portion 27 of the slide plate 2 in the second position A do not overlap on the projection surface.

[0077] For example, on the projection surface, the projection area of ​​the second hollow part 27 in the second position A of the slide plate 2 is the third projection area, and the projection area of ​​the second hollow part 27 in the first position B of the slide plate 2 is the fourth projection area. The third projection area and the fourth projection area do not overlap, and the water replenishment hole 1b is located in the fourth projection area corresponding to the position of the hollow area 2a.

[0078] The projection shape of the second hollow part 27 along the top and bottom direction can be annular, that is, the shape of the third projection area and the shape of the fourth projection area can be annular. 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 inlet hole 1b can be set on the housing 1 at the position of the fourth projection area corresponding to the hollow area 2a. In this way, the water inlet hole 1b can be aligned with its hollow area 2a when the slide plate 2 is in the first position B, and staggered from its hollow area 2a when the slide plate 2 is in the second position A, making the setting position more flexible.

[0079] For example, in one embodiment, please refer to Figures 1, 2, 3, 5, 6 and 7. There are multiple hollow areas 2a. For example, there can be 8 hollow areas 2a. The 8 hollow areas 2a are arranged circumferentially in the hollow area. In this way, when the mop plate 2 rotates along the center, the water replenishment hole 1b replenishes water to the mop under the multiple hollow areas 2a, thereby improving the uniformity of water replenishment to the mop.

[0080] In one embodiment, referring to Figures 1, 2, 3, 5, 6, and 7, anti-collision ribs 3 are provided on the outer periphery of the sliding plate 2. For example, the anti-collision ribs 3 can be arranged around the outer periphery of the second connecting portion 24 or the third connecting portion 28, thereby reducing damage to the sliding plate 2 when it collides with obstacles such as walls or seats, and improving the service life of the cleaning equipment 100.

[0081] For example, in one embodiment, the anti-collision rib 3 can be made of materials such as rubber or silicone.

[0082] In one embodiment, the mop pad 2 is detachably connected to the housing 1. For example, the mop pad 2 and housing 1 can be magnetically connected or snap-fit ​​connected. This allows for efficient replacement of the mop cloth and mop pad 2, as well as the inspection or removal of foreign objects such as hair.

[0083] In one embodiment, referring to FIG4, the housing 1 is formed with a guide groove 1a. The guide groove 1a includes an outward swing portion 1a1, a transition portion 1a2, and a retractable portion 1a3. The outward swing portion 1a1 may be located at the edge of the housing 1, and the retractable portion 1a3 may be located on the side of the outward swing portion 1a1 facing the center of the housing 1. The transition portion 1a2 bends to connect the outward swing portion 1a1 and the retractable portion 1a3. The outward swing portion 1a1 corresponds to the second position A, the transition portion 1a2 corresponds to the transition position, and the retractable portion 1a3 corresponds to the first position B.

[0084] In one embodiment, the housing 1 has a water storage cavity, and the cleaning device 100 includes a water supply component, a water replenishment controller and a first sensor. The water supply component is connected to the water storage cavity and the water replenishment hole 1b. The first sensor is used to detect the position of the slide 2. The water replenishment controller is communicatively connected to the water supply component and the first sensor respectively. When the slide 2 is in the first position B, the water replenishment controller controls the water supply component to supply water to the water replenishment hole 1b.

[0085] For example, the first sensor can detect whether the mop 2 is in a first position B, a second position A, or a transition position. The water replenishment controller can communicate with the water supply component and the first sensor via a local area network, Bluetooth, Wi-Fi, or Ethernet cable. When the first sensor detects that the mop 2 is in the first position B, it can send a command to the water replenishment controller. After receiving the command, the water replenishment controller can send a water replenishment command to the water supply component. After receiving the water replenishment command, the water supply component is activated to deliver water from the water storage chamber to the water replenishment hole 1b to replenish the mop under the perforated area 2a. This design offers a high degree of intelligence, excellent cleaning performance, and a good user experience.

[0086] In one embodiment, for example, the water supply component may be a water pump, such as a peristaltic pump, capable of slowly and quantitatively supplying water to the water inlet 1b.

[0087] In one embodiment, the cleaning device 100 includes a swing device and a second sensor. The second sensor and the swing device are respectively connected to a water replenishment controller. The second sensor is used to obtain the walking distance of the cleaning device 100, and the swing device is used to control the slide 2 to switch between a first position B and a second position A.

[0088] For example, the second sensor can acquire the distance traveled between the current position of the cleaning device 100 and the last water replenishment position, and the swing device can control the mop 2 to switch between the first position B and the second position A. The water replenishment controller can communicate with the second sensor and the swing device via a local area network, Bluetooth, WIFI, or network cable. In this way, when it is determined that the cleaning device 100 is in a state of walking away from the wall, and the distance traveled by the second sensor reaches the set distance, it can send a command to the water replenishment controller. After receiving the command, the water replenishment controller sends a command to the swing device, which can then control the mop 2 to switch from the second position A to the first position B. When the first sensor detects that the mop 2 is in the first position B, it can send a command to the water replenishment controller. After receiving the command, the water replenishment controller can send a water replenishment command to the water supply component. After receiving the water replenishment command, the water supply component is driven to deliver water from the water storage chamber to the water replenishment hole 1b to replenish the mop under the perforated area 2a.

[0089] Another aspect of this application provides a control method, including the cleaning device in any of the above embodiments. The cleaning device includes a water supply component. Please refer to Figure 8. The control method includes:

[0090] S1. Determine that the mop is in the first position, and control the water supply component to supply water to the water inlet to replenish the mop and / or the mop cloth.

[0091] For example, when the first sensor detects that the mop pad 2 is in the first position B, it can send a command to the water replenishment controller. After receiving the command, the water replenishment controller can send a water replenishment command to the water pump. After receiving the water replenishment command, the water pump will start to deliver water from the water storage chamber to the water replenishment hole 1b to replenish the mop pad under the perforated area 2a. In this way, the situation where excessive water on the mop pad leads to poor cleaning effect can be reduced. This method has a high degree of intelligence, good cleaning effect, and good user experience.

[0092] In one embodiment, the cleaning device 100 has a wall-moving state, and the control method includes:

[0093] S2. Determine that the cleaning equipment is in a state of walking away from the wall. When the mop is in the first position, and the cleaning equipment has traveled a set distance, control the water supply component to turn on to replenish water to the mop and / or the mop.

[0094] In this way, when the cleaning device 100 is determined to be in a state of walking away from the wall, after the walking distance obtained by the second sensor reaches the set distance, it can send a command to the water replenishment controller. After receiving the command, the water replenishment controller sends a command to the swing device, which can then control the mop 2 to switch from the second position A to the first position B. When the first sensor detects that the mop 2 is in the first position B, it can send a command to the water replenishment controller. After receiving the command, the water replenishment controller can send a water replenishment command to the water pump. After receiving the water replenishment command, the water pump is driven to deliver the water in the water storage chamber to the water replenishment hole 1b to replenish the mop under the hollow area 2a.

[0095] In one embodiment, the control method includes:

[0096] S21. Set multiple preset water volumes and establish a mapping relationship between the preset water volumes and the preset distances. When the cleaning equipment travels to the preset distance, it replenishes the mop and / or the mop plate with water corresponding to the preset water volume.

[0097] The system allows for 30 water volume settings, categorized from level 1 to level 30, with corresponding distance settings ranging from 230cm to 85cm, in 5cm increments. Specifically, level 1 corresponds to a distance of 230cm, level 7 to 200cm, level 13 to 170cm, level 23 to 120cm, and level 30 to 85cm. Level 1 can be defined as ultra-low water volume, level 7 as low water volume, level 13 as medium water volume, and level 23 as high water volume. Users can select the appropriate setting based on their needs, or the cleaning device can intelligently select the setting based on the degree of dirt on the floor.

[0098] Taking a set water volume of 1 and a set travel distance of 230cm as an example, when the cleaning device 100 is in a state of moving away from the wall, the mop is replenished with the set water volume of 1 every time the cleaning device 100 moves to 230cm; as another example, taking a set water volume of 7 and a set travel distance of 200cm as an example, when the cleaning device 100 is in a state of moving away from the wall, the mop is replenished with the set water volume of 7 every time the cleaning device 100 moves to 200cm.

[0099] The set water volume for each level can be the same, meaning the set water volume corresponding to different set distances is the same. For example, the water replenishment volume for every 200cm traveled is the same as the water replenishment volume for every 230cm traveled. In other embodiments, the set water volume for each level can be different, for example, the water replenishment volume for every 200cm traveled is different from the water replenishment volume for every 230cm traveled.

[0100] It should be noted that the "walking away from the wall" state refers to a relatively spacious mopping and sweeping environment with few obstacles.

[0101] In one embodiment, the cleaning device 100 has a wall-walking state, and the control method includes:

[0102] S3. Determine that the cleaning equipment is in a wall-walking state. When the tray is in the first position, obtain the first walking distance between the current position of the cleaning equipment and the last water replenishment position.

[0103] S4. Based on the ratio between the first travel distance and the set distance, control the water supply component; wherein, the water replenishment position is the position of the cleaning equipment when the water supply component replenishes water to the mop.

[0104] It should be noted that the "walking along the wall" state does not only refer to walking along a wall, but can also be walking along an object with a long line, such as a sofa. When the cleaning device 100 is in the "walking along the wall" state, the mop 2 may avoid some obstacles such as corners and table legs, causing the mop 2 to switch from the second position A to the first position B.

[0105] It is understandable that the water replenishment location is the position of the cleaning equipment 100 when the water supply unit begins to replenish water to the mop.

[0106] Here, after determining that the cleaning device 100 is in the wall-walking state, when the tray 2 is in the first position B, the second sensor can obtain the first walking distance between the current position of the cleaning device 100 and the last water replenishment position, and then calculate the ratio between the first walking distance and the selected set distance as the basis for controlling the water supply component to start.

[0107] In one embodiment, the control method includes:

[0108] S5. If the ratio is less than the set time, then no water will be added to the mop and / or the mop cloth;

[0109] S6. If the ratio is not less than the set duration, then add water to the mop and / or the mop cloth.

[0110] Here, when the mop 2 is in the first position B, if the ratio is less than the set time, it means that the first travel distance is short and the distance to the last water replenishment position is close. If water is added to the mop, it will result in too much water on the mop. If the ratio is not less than the set time, it means that the first travel distance is long and the distance to the last water replenishment position is far. Water can be supplied to the mop through the water replenishment hole 1b by turning on the water supply component, thereby replenishing the mop and reducing the dry mopping situation.

[0111] In one embodiment, the set duration can be between 1 second and 2 seconds. For example, the set duration can be 1 second, 1.5 seconds, or 2 seconds, etc. Taking 1 second as an example, when the set water volume of level 23 and the set distance of 120 cm are selected, if the mop 2 is in the first position B and the first distance traveled is 200 cm, then the ratio is 1.6, which is greater than 1 second. The water replenishment controller will control the water supply component to turn on to replenish water to the mop. If the mop 2 is in the first position B and the first distance traveled is 60 cm, then the ratio is 0.5, which is less than 1 second. In this case, the water supply component will be turned off, and no water will be replenished to the mop.

[0112] In one embodiment, the water replenishment time can be determined based on the ratio between the first travel distance and the selected set distance. For example, when a set water volume of 23 levels and a set distance of 120cm are selected, if the mop 2 is in the first position B and the first travel distance is 200cm, then the ratio is 1.6, which is greater than 1s. The water replenishment controller will control the water supply component to turn on to replenish the mop with the set water volume of 23 levels, and the water replenishment time is 1.6s.

[0113] In one embodiment, the control method includes:

[0114] S7. When the tray is in the second position, determine the second travel distance between the current position of the cleaning equipment and the last water replenishment position;

[0115] S8. If the second travel distance is not less than the set upper limit distance, control the slide to switch from the second position to the first position, and control the water supply component to turn on.

[0116] It is understandable that when the cleaning device 100 is moving along the wall, the tray 2 will not passively switch to the first position B when there are no obstacles. In other words, it will only actively avoid obstacles and retract to the first position B.

[0117] In this way, when the mop 2 is in the second position A, the second travel distance between the current position of the cleaning device 100 and the last water replenishment position is determined. If the second travel distance is greater than or equal to the set upper limit distance, the mop 2 can be switched from the second position A to the first position B by the swing device, and the water supply component is opened by the water replenishment controller to supply water to the water replenishment hole 1b, thereby replenishing the mop cloth with water, reducing the situation of dry mopping due to lack of water in the mop cloth, and improving the cleaning effect.

[0118] For example, in one embodiment, the upper limit distance can be set to 10m. For instance, when the distance along the wall is 20m, by setting the upper limit distance to 10m, when the second travel distance reaches 10m, the mop 2 can be controlled to switch to the first position B, and the water supply component can be controlled to replenish water to the mop.

[0119] In one embodiment, when the cleaning device 100 is not trapped, in complex scenarios such as corners or chair legs, the logic used in the wall-walking state can be applied. The ratio of the accumulated walking distance to the set distance can be used to determine the water supply. If the ratio is less than the set time, the water supply is turned off; if the ratio is not less than the set time, the water supply is turned on. That is, when the cleaning device 100 actively avoids and switches the tray 2 to the first position B, if the ratio of the first walking distance to the set distance is less than the set time, the water supply is turned off and no water is replenished, but the first walking distance is recorded and added to the next water replenishment determination.

[0120] It is understandable that being trapped can refer to being in a closed space with boundaries, where there are obstacles such as corners, tables and chairs, causing the slide 2 to repeatedly switch to the first position B.

[0121] In one embodiment, the cleaning device 100 is in a trapped state, and the control method includes:

[0122] S9. Upon determining that the cleaning equipment is in the trapped state, control the water supply component to shut off.

[0123] In this way, when it is determined that the cleaning equipment 100 is trapped, even if the ratio of the accumulated walking distance to the set distance is greater than the set time, in order to reduce the situation of repeated water replenishment and mopping in the trapped space, which would cause excessive water stains, the water supply component can be shut off by the water replenishment controller. Then, water can be replenished after the cleaning equipment 100 is freed from the trapped state.

[0124] In one embodiment, when the size of the walking space of the cleaning device 100 is not greater than a set size, it is determined that the cleaning device 100 is in a trapped state.

[0125] For example, the set size can be 1.05 times, 1.06 times, 1.07 times, 1.08 times, 1.09 times, or 1.1 times the floor area of ​​the cleaning pen, etc. The shape of the walking space is not limited; for example, the walking space can be a circle, triangle, rectangle, or irregular shape when projected along the top-bottom direction. In some embodiments, the head of the walking space along the top-bottom direction can be a shape with a certain opening, but the size of the opening is smaller than the diameter of the cleaning device 100. In this way, 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 shut off by the water replenishment controller to reduce the situation where repeated water replenishment and mopping in the trapped space leads to excessive water stains.

[0126] For example, in one embodiment, the cleaning device 100 may be equipped with a camera, lidar or other sensors to sense the surroundings and determine whether the cleaning device 100 is in a state of walking away from the wall, walking along the wall, or being trapped.

[0127] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
