[0089] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0090] Reference below Figures 1-17 A cleaning device 100 according to an embodiment of the present invention is described.

[0091] Reference Figure 2 、 Figure 4 and Figure 8According to the first embodiment of the present invention, a cleaning device 100 includes a device body 1, a wiping assembly 2, a lifting assembly, a shielding plate 4, and a driving assembly 5. The wiping assembly 2 is arranged at the bottom 11 of the device body 1 and has a wiping surface 21. The lifting assembly is installed on the device body 1 and is connected to the wiping assembly 2. The lifting assembly is used to drive the wiping assembly 2 to move between an extended position and a retracted position. The retracted position is higher than the extended position. The shielding plate 4 has a first position and a second position. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the extended position, the wiping surface 21 is exposed. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the shielding plate 4 shields the wiping surface 21. When the shielding plate 4 is in the second position, the shielding plate 4 is used to avoid the lifting space of the wiping assembly 2. The driving assembly 5 is arranged on the device body 1 and is connected to the shielding plate 4. The driving assembly 5 is used to drive the shielding plate 4 to move between the first position and the second position.

[0092] The device body 1 can serve as the basic carrier of the cleaning device 100. The device body 1 can be an integrated structure or a combined structure formed by the cooperation of multiple components. The device body 1 plays a role in carrying and protecting other components of the cleaning device 100, among which other components include a baffle 4, a lifting assembly, a wiping assembly 2 and a driving assembly 5, but are not limited to these.

[0093] The lifting assembly is connected to the wiping assembly 2 to control the lifting and lowering of the wiping assembly 2 between the extended position and the retracted position. For example, the lifting assembly can use a pull rope, a gear rack, a cam, a screw rod, etc. to control the movement of the wiping assembly 2. The retracted position is higher than the extended position. The lifting assembly drives the wiping assembly 2 to move in the up and down direction between the retracted position and the extended position. When the shielding plate 4 is in the first position, the wiping assembly 2 is in the retracted position. The distance between the wiping assembly 2 in the retracted position and the working surface is larger, which can avoid the shielding plate 4 so that the shielding plate 4 can be smoothly switched to the first position, so that the shielding plate 4 effectively shields the wiping surface 21.

[0094] The drive assembly 5 is connected to the shielding plate 4 and is used to drive the shielding plate 4 to move, thereby exposing or shielding the wiping surface 21. Furthermore, the drive assembly 5 drives the shielding plate 4 to move between a first position and a second position, thereby clearing the lifting space of the wiping assembly 2, thereby allowing the wiping assembly 2 to move more smoothly between the retracted position and the extended position. Whether the wiping surface 21 is exposed or shielded can be determined based on the surface to be worked on.

[0095] For example, whether to expose the wiping surface 21 or to block the wiping surface 21 can be determined based on the material of the surface to be worked on. If the material of the surface to be worked on is suitable for wiping by the wiping component 2, the driving component 5 drives the shielding plate 4 to move to expose the wiping surface 21. If the material of the surface to be worked on is not suitable for wiping by the wiping component 2, the driving component 5 drives the shielding plate 4 to move to block the wiping surface 21.

[0096] For another example, whether to expose the wiping surface 21 or to block the wiping surface 21 can be determined based on the degree of dirtiness of the surface to be worked on. If the degree of dirtiness of the surface to be worked on is large, the driving component 5 drives the shielding plate 4 to move to expose the wiping surface 21. If the degree of dirtiness of the surface to be worked on is small, the driving component 5 drives the shielding plate 4 to move to block the wiping surface 21.

[0097] In addition, the user can also set multiple cleaning areas and determine whether each cleaning area needs to be wiped by the wiping component 2. The cleaning device 100 can expose the wiping surface 21 or cover the wiping surface 21 in different cleaning areas according to the user settings.

[0098] For example, the work surface can be divided into a first work surface and a second work surface. The first work surface and the second work surface can be distinguished by material. The first work surface can be a hard surface such as tile, flooring, or cement flooring, while the second work surface can be a soft surface such as fiber (such as carpet). The first and second work surfaces can also be distinguished by the degree of dirtiness of the work surface, with the first work surface being more heavily soiled than the second work surface. Alternatively, the first and second work surfaces can be set by the user.

[0099] During the process of the wiping component 2 wiping the first working surface, when the cleaning device 100 is about to run to the second working surface, the driving component 5 can be controlled to drive the baffle 4 to move to the second position to avoid the lifting space of the wiping component 2. After the lifting component drives the wiping component 2 to move upward from the extended position to the retracted position, the driving component 5 drives the baffle 4 to move from the second position to the first position, so that the baffle 4 is located on the side of the wiping component 2 facing the first working surface to block the wiping surface 21 of the baffle 4, so that when the cleaning device 100 runs to the second working surface, the baffle 4 blocks the wiping surface 21 and the second working surface, and the wiping surface 21 will not contact the second working surface, thereby effectively preventing the second working surface from being contaminated or wetted by the wiping surface 21.

[0100] When the cleaning equipment 100 runs from the second working surface to the first working surface, the driving component 5 drives the shielding plate 4 to move from the first position to the second position to avoid the lifting space of the wiping component 2. After the lifting component drives the wiping component 2 to move downward from the retracted position to the extended position, the driving component 5 drives the shielding plate 4 to move from the second position to the first position, so that the shielding plate 4 is located on the side of the wiping component 2 away from the first working surface to expose the wiping surface 21 for wiping the first working surface.

[0101] By connecting the wiping assembly 2 with the lifting assembly, the wiping assembly 2 can be lifted and lowered at the bottom 11 of the device body 1, and the driving assembly 5 is set on the device body 1 and the baffle 4 is connected to the driving assembly 5, so that the driving assembly 5 can drive the baffle 4 to move to expose the wiping surface 21, so that the wiping surface 21 can wipe the first working surface. The driving assembly 5 can also drive the baffle 4 to move to cover the wiping surface 21 to effectively isolate the wiping surface 21 from the second working surface, thereby effectively preventing the wiping assembly 2 from causing contamination to the second working surface. For example, when the cleaning equipment 100 runs to the second working surface, the baffle 4 covers the wiping surface 21 to avoid contact between the wiping surface 21 and the second working surface, thereby effectively preventing the second working surface from being contaminated or wetted by the wiping surface 21.

[0102] Optionally, the wiping assembly 2 can be a flat plate type, a roller type, a crawler type, etc. For example, the wiping member can be a mop, a brush, a sponge, etc. The wiping member can be detachable or non-detachable.

[0103] The wiping surface 21 can be in various shapes and sizes, for example, square, rectangular, polygonal, circular, oval, etc. The specific shape and size of the wiping surface 21 are not limited and can be determined according to the specific shape and size of the wiper.

[0104] Optionally, when the shielding plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the projection of the wiping surface 21 on the shielding plate 4 falls completely or partially on the shielding plate 4, so that the shielding plate 4 can completely or partially cover the wiping surface 21, which is beneficial to improving the shielding effect of the shielding plate 4.

[0105] The shielding plate 4 can adopt a variety of shapes and sizes, such as square, rectangular, polygonal, circular, and oval. The shape of the shielding plate 4 can be the same as that of the wiper, or it can be different from the shape of the wiper. The size of the shielding plate 4 can be equal to, slightly larger than, or slightly smaller than the size of the wiper. The specific shape and size of the shielding plate 4 are not limited, as long as the shielding plate 4 ensures that when the cleaning device 100 moves to the second working surface, the wiper does not come into contact with the second working surface.

[0106] In some embodiments, the wiper may be a dry wiper to achieve a dry cleaning effect on the work surface. Of course, the wiper may also be a wet wiper containing a cleaning liquid to achieve a wet cleaning effect on the work surface. The cleaning liquid may be water, a liquid containing 84 disinfectant, ethanol, a liquid containing sodium chloride, etc. For example, the cleaning device 100 includes a water tank, and the cleaning liquid in the water tank can be dripped into the wiper or sprayed onto the work surface and wiped away by the wiper.

[0107] In some embodiments, the cleaning device 100 is adapted to cooperate with a cleaning base station, which is used to clean and / or charge the cleaning device 100. The cleaning device 100 further includes a first detection component. The first detection component is used to detect the degree of dirtiness of the wiping member. When the first detection component detects that the degree of dirtiness of the wiping member has reached a threshold value, the cleaning device 100 will run to the base station and clean the wiping member through the base station. In other embodiments, the cleaning device 100 further includes a prompt component. When the wiping member can be detachably mounted on the wiping component 2, if the first detection component detects that the degree of dirtiness of the wiping member has reached a threshold value, the prompt component will issue a prompt message to prompt the user to replace the wiping member. The prompt component can be a display screen, an LED light, a speaker, a vibrator, etc. The prompt message can be text or images output by the display screen; light or flashing emitted by an LED light; sound played by a speaker; vibration generated by a vibrator, etc. The first detection component can be a camera, an ultrasonic detector, etc.

[0108] In some embodiments, the cleaning device 100 further includes a processor and a second detection component, and the second detection component and the drive component 5 are both connected to the controller. The second detection component is used to detect the surrounding environment of the cleaning device 100. For example, the second detection component can detect the materials in the surrounding environment of the cleaning device 100. The detection objects may include whether the surrounding environment includes materials that are not suitable for wiping, such as the second working surface. The second detection component can also be used to detect the degree of dirtiness of the surface to be worked in the surrounding environment of the cleaning device 100, and determine whether it is necessary to cover the wiping surface 21 according to the degree of dirtiness of the surface to be worked, or detect whether the cleaning device 100 has run to the boundary of multiple cleaning areas set by the user.

[0109] In some embodiments, the second detection component can be an image acquisition device, an infrared sensor, an ultrasonic sensor, etc. For example, the image acquisition device provided on the cleaning device 100 can acquire image information of the surroundings of the cleaning device, and the cleaning device 100 can identify whether it has approached or entered the second working surface, such as the surface of a carpet, from the acquired image information. Alternatively, an infrared sensor or ultrasonic sensor provided on the cleaning device 100 detects the working surface in front of or at the bottom of the cleaning device to determine when the cleaning device 100 has approached or entered the second working surface. In other embodiments, the second sensor can also be other sensors that can detect the surrounding environment.

[0110] If it is detected that the second working surface is within a first preset distance in the direction of the cleaning device 100's advance, it means that the cleaning device 100 is about to run to the second working surface area. The first preset distance can be the distance between the front end of the cleaning device 100 in the running direction and the edge of the second working surface, or the first preset distance can be the distance between the edge of the wiping component 2 on the side close to the second working surface and the edge of the second working surface. When the second detection component detects that the cleaning device 100 is about to run or has run to the second working surface, the controller drives the lifting component in response to the signal sent by the second detection component to drive the wiping component 2 to rise, and starts the driving component 5 to drive the shielding plate 4 to shield the wiping surface 21.

[0111] If the first working surface is detected within a second preset distance in the direction of travel of the cleaning device 100, it indicates that the cleaning device 100 is about to reach the first working surface area. The second preset distance can be the distance between the front end of the cleaning device 100 in the direction of travel and the edge of the first working surface, or the second preset distance can be the distance between the edge of the wiping assembly 2 on the side closest to the first working surface and the edge of the first working surface. When the second detection assembly detects that the cleaning device 100 is about to move or has already moved to the first working surface, it sends a signal. In response to the signal sent by the second detection assembly, the controller activates the drive assembly 5, drives the shielding plate 4 to expose the wiping surface 21, and drives the wiping assembly 2 to descend.

[0112] According to the cleaning device 100 of the embodiment of the present invention, the wiping component 2 is connected to the lifting component so that the wiping component 2 can be lifted and lowered at the bottom 11 of the device body 1, and the driving component 5 is set on the device body 1 and the baffle 4 is connected to the driving component 5, so that the driving component 5 can drive the baffle 4 to move to expose the wiping surface 21, so that the wiping surface 21 can wipe the first working surface, and the driving component 5 can also drive the baffle 4 to move to block the wiping surface 21 to effectively isolate the wiping surface 21 from the second working surface, thereby effectively preventing the wiping component 2 from causing contamination to the second working surface; and, by driving the baffle 4 to move between the first position and the second position by the driving component 5 to avoid the lifting space of the wiping component 2, the wiping component 2 can complete the lifting action more smoothly.

[0113] Reference Figure 2 、 Figure 3 and Figure 5 According to some embodiments of the present invention, the device body 1 is formed with a accommodating cavity, the opening of the accommodating cavity is opened at the bottom 11 of the device body 1, and the lifting assembly and the wiping assembly 2 are accommodated in the accommodating cavity, or the lifting assembly is arranged in the accommodating cavity, at least a portion of the lifting assembly passes through the opening and the lifting assembly is connected to the wiping assembly 2. By accommodating the lifting assembly and the wiping assembly 2 in the accommodating cavity, at least a portion of the lifting assembly passes through the opening and the lifting assembly is connected to the wiping assembly 2, the lifting assembly is used to drive the wiping assembly 2 to be accommodated in the accommodating cavity or close to the opening when the cleaning device 100 is about to move to the second working surface, that is, the lifting assembly drives the wiping assembly 2 to rise to leave the working surface and move from the extended position to the retracted position; the lifting assembly is also used to drive the wiping assembly 2 away from the opening and the accommodating cavity after the cleaning device 100 moves from the second working surface to the working surface, that is, drive the wiping assembly 2 to descend and move from the retracted position to the extended position to wipe the first working surface.

[0114] Reference Figure 2 、 Figure 4 and Figure 6 According to some embodiments of the present invention, the projection of the shielding plate 4 on the surface to be worked on when it is in the second position does not completely overlap with the projection of the equipment main body 1 on the surface to be worked on. The first position and the second position can both be lower than the bottom surface of the equipment main body 1, which can make full use of the space below the equipment main body 1, making the overall structure of the shielding plate 4 and the equipment main body 1 more compact, and reducing the occupation of the external space of the equipment main body 1 by the shielding plate 4, which is conducive to the miniaturization of the cleaning equipment 100 and facilitates the transportation and storage of the cleaning equipment 100.

[0115] Reference Figure 3 and Figure 5According to some embodiments of the present invention, the first position and the second position are at the same height. When the shielding plate 4 is in the second position, the first position and the second position are at the same height. This ensures that the shielding plate 4 can avoid the lifting space required for the wiping assembly 2 when moving from the first position to the second position, so as to effectively avoid interference between the shielding plate 4 and the wiping assembly 2, so that the wiping assembly 2 can move more smoothly between the retracted position and the extended position.

[0116] For example, the movement process of the baffle 4 between the first position and the second position can be: when the cleaning device 100 is cleaning the area outside the second working surface, the baffle 4 is in the first position and the wiping assembly 2 is in the extended position; if the cleaning device 100 is about to run to the second working surface area, the driving assembly 5 drives the baffle 4 to move from the first position to the second position, that is, the driving assembly 5 drives the baffle 4 to move in the direction away from the center of the device body 1 to avoid the lifting space of the wiping assembly 2. After the lifting assembly drives the wiping assembly 2 to move upward from the extended position to the retracted position, the driving assembly 5 drives the baffle 4 from the second position to the first position to block the wiping surface 21, which can effectively prevent the wiping surface 21 from contaminating or wetting the second working surface.

[0117] If the cleaning device 100 moves from the second working surface area to the first working surface, the driving assembly 5 drives the shielding plate 4 to move from the first position to the second position. That is, the driving assembly 5 drives the shielding plate 4 to move away from the center of the device body 1 to avoid the lifting space of the wiping assembly 2. The lifting assembly drives the wiping assembly 2 to move downward from the retracted position to the extended position, so that the wiping assembly 2 can wipe the first working surface. When the wiping assembly 2 moves to the extended position, the driving assembly 5 drives the shielding plate 4 to move from the second position to the first position, reducing the horizontal space occupied by the automatic cleaning device 100.

[0118] Reference Figure 5 、 Figure 7 and Figure 10 According to some embodiments of the present invention, the lifting assembly and the wiping assembly 2 are connected via a connecting shaft 22, and the shielding plate 4 is provided with a relief structure 41 for avoiding the connecting shaft 22. The relief structure 41 facilitates the accommodation of the connecting shaft 22, allowing the shielding plate 4 and the wiping assembly 2 to be closely arranged below the device body 1, thereby making the overall structure of the cleaning device 100 compact and facilitating the transportation or storage of the cleaning device 100. For example, when the shielding plate 4 is in the first position and the wiping assembly 2 is in the extended position, the relief structure 41 provided on the shielding plate 4 for avoiding the connecting shaft 22 can maintain a compact structure of the shielding plate 4 and the wiping assembly 2.

[0119] Reference Figure 7 、 Figure 10 and Figure 12 According to some embodiments of the present invention, the avoidance structure 41 includes a avoidance opening 411 provided on the shielding plate 4, and the avoidance opening 411 extends in the direction of movement of the shielding plate 4. When the shielding plate 4 moves between the first position and the second position, and the avoidance opening 411 extends in the direction of movement of the shielding plate 4, interference between the shielding plate 4 and the wiping assembly 2 can be effectively avoided. For example, when the wiping assembly 2 is in the extended position and the driving assembly 5 drives the shielding plate 4 to move between the first position and the second position, the avoidance opening 411 extends in the arrangement direction of the first position and the second position, effectively avoiding interference between the connecting shaft 22 and the shielding plate 4, allowing the shielding plate 4 to move more smoothly between the first position and the second position.

[0120] Reference Figure 8 、 Figure 10 and Figure 12 According to some embodiments of the present invention, the avoidance structure 41 further includes a sealing structure 412. The sealing structure 412 is disposed within the avoidance opening 411 to seal the avoidance opening 411. The sealing structure 412 can elastically deform or move to avoid the connection shaft 22. In some embodiments of the present invention, the sealing structure 412 can be made of a water-absorbing material to absorb wastewater from the wiping surface. The sealing structure 412 disposed within the avoidance opening 411 can increase the area of ​​the avoidance opening 411 that is blocked, thereby enhancing the shielding effect of the shielding plate 4 on the wiping surface. When the connecting shaft 22 contacts the sealing structure 412 at the avoidance opening 411, the sealing structure 412 can be elastically deformed or moved, so that the blocking area of ​​the sealing structure 412 at the avoidance opening 411 is reduced, so that the connecting shaft 22 can be accommodated therein. When the connecting shaft 22 moves out of the avoidance opening 411, the sealing structure 412 can rely on its own elasticity to restore its original shape or move to a position covering the avoidance opening 411, so as to shield the avoidance opening 411.

[0121] Reference Figure 8 、 Figure 10 and Figure 12 The sealing structure 412 includes a soft sealing sheet 4123 that can be elastically deformed to avoid the connecting shaft 22. When the connecting shaft 22 contacts the soft sealing sheet 4123, the soft sealing sheet 4123 can be elastically deformed, thereby reducing the shielding area of ​​the soft sealing sheet 4123 at the avoidance opening 411, thereby facilitating the accommodation of the connecting shaft 22. When the connecting shaft 22 moves out of the avoidance opening 411, the soft sealing sheet 4123 can return to its original shape due to its own elasticity, thereby shielding the avoidance opening 411.

[0122] Reference Figure 10 and Figure 12According to some embodiments of the present invention, the soft sealing sheet 4123 includes a first sealing sheet 4121 and a second sealing sheet 4122. The avoidance opening 411 includes a first side wall 4111 and a second side wall 4112 disposed opposite each other along the width direction of the avoidance opening 411. The width direction of the avoidance opening 411 intersects with the movement direction of the shielding plate 4. The first sealing sheet 4121 is fixed to the first side wall 4111, and the second sealing sheet 4122 is fixed to the second side wall 4112. The first sealing sheet 4121 and the second sealing sheet 4122 cooperate to seal at least a portion of the avoidance opening 411. The first sealing sheet 4121 and the second sealing sheet 4122 cooperate to seal at least a portion of the avoidance opening 411, thereby increasing the shielding area of ​​the avoidance opening 411 and enhancing the sealing effect at the avoidance opening 411. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the first sealing sheet 4121 and the second sealing sheet 4122 cooperate to effectively block at least a portion of the avoidance opening 411, so that the shielding plate 4 effectively blocks the wiping surface 21, reducing or avoiding the second working surface from being contaminated or wetted by the wiping surface 21.

[0123] Among them, the first sealing sheet 4121 and the second sealing sheet 4122 cooperate together to seal at least part of the avoidance opening 411, which may include the following situations: for example, the first sealing sheet 4121 and the second sealing sheet 4122 cooperate together to seal the entire avoidance opening 411; for another example, the first sealing sheet 4121 and the second sealing sheet 4122 cooperate together to seal a part of the avoidance opening 411.

[0124] For example, the first sealing sheet 4121 and / or the second sealing sheet 4122 can be integrally formed on the shielding plate 4, or be provided on the shielding plate 4 by bonding, adsorption connection, snap connection, etc.

[0125] Reference Figure 10 and Figure 12 According to some embodiments of the present invention, there are multiple first sealing sheets 4121 and multiple second sealing sheets 4122, and the multiple first sealing sheets 4121 or multiple second sealing sheets 4122 are arranged along the extension direction of the avoidance opening 411. By arranging the multiple first sealing sheets 4121 or multiple second sealing sheets 4122 along the extension direction of the avoidance opening 411, the shielding area at the avoidance opening 411 can be increased, thereby enhancing the sealing effect of the first sealing sheet 4121 and the second sealing sheet 4122 on the avoidance opening 411. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the multiple first sealing sheets 4121 and the multiple second sealing sheets 4122 cooperate to effectively shield the avoidance opening 411, thereby enhancing the shielding effect of the shielding plate 4 on the wiping surface 21, and effectively preventing the second working surface from being contaminated or wetted by the wiping surface 21.

[0126] In the description of the present invention, “plurality” means two or more.

[0127] Reference Figure 10 and Figure 12 According to some embodiments of the present invention, the first sealing sheet 4121 and the second sealing sheet 4122 are alternately arranged in the extension direction of the avoidance opening 411. By arranging multiple first sealing sheets 4121 or multiple second sealing sheets 4122 along the extension direction of the avoidance opening 411, and by alternatingly arranging the first sealing sheets 4121 and the second sealing sheets 4122 in the extension direction of the avoidance opening 411, the sealing structure 412 can be formed into a continuous structure, thereby further enhancing the sealing effect of the first sealing sheets 4121 and the second sealing sheets 4122 on the avoidance opening 411. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the shielding plate 4 effectively shields the wiping surface 21 to prevent the second working surface from being contaminated or wetted by the wiping surface 21.

[0128] Reference Figure 10 and Figure 12 According to some embodiments of the present invention, the first sealing sheet 4121 and the second sealing sheet 4122 are both tooth-shaped, so that the first sealing sheet 4121 and the second sealing sheet 4122 can be alternately arranged in the extension direction of the avoidance opening 411, so that the sealing structure 412 forms a continuous sealing structure, thereby enhancing the sealing effect of the first sealing sheet 4121 and the second sealing sheet 4122 on the avoidance opening 411.

[0129] Reference Figure 14 According to some embodiments of the present invention, a soft sealing sheet 4123 is fixed to the inner wall of the avoidance opening 411, and a avoidance cutout 4124 is formed on the soft sealing sheet 4123 for avoiding the connecting shaft 22. The avoidance cutout 4124 can facilitate the accommodation of the connecting shaft 22 therein. For example, when the shielding plate 4 is in the first position and the wiping assembly 2 is in the extended position, the avoidance cutout 4124 can be used to avoid the connecting shaft 22. When the connecting shaft 22 moves relative to the shielding plate 4 into the avoidance opening 411, the soft sealing sheet 4123 at the avoidance opening 411 can be elastically deformed when the connecting shaft 22 contacts the soft sealing sheet 4123, thereby increasing the opening of the avoidance cutout 4124 and facilitating the accommodation of the connecting shaft 22 therein. When the connecting shaft 22 moves out of the avoidance cutout 4124, the soft sealing sheet 4123 can return to its original shape by virtue of its own elasticity, thereby continuing to shield the avoidance opening 411.

[0130] Reference Figure 15-17The sealing structure 412 includes a hard sealing sheet 4126 that can move to cover or open the avoidance opening 411. The movement direction of the hard sealing sheet 4126 intersects with the movement direction of the shielding plate 4. When the connecting shaft 22 contacts the hard sealing sheet 4126 at the avoidance opening 411, the hard sealing sheet 4126 can move to reduce the area blocked by the hard sealing sheet 4126 at the avoidance opening 411, thereby facilitating the accommodation of the connecting shaft 22. When the connecting shaft 22 moves out of the avoidance opening 411, the hard sealing sheet 4126 can move to a position covering the avoidance opening 411, thereby shielding the avoidance opening 411.

[0131] Reference Figure 15-17 The hard sealing piece 4126 is connected to the shielding plate 4 through a return spring 4125. The return spring 4125 is retractable in the movement direction of the hard sealing piece 4126. The return spring 4125 is used to drive the hard sealing piece 4126 to move to a position covering the avoidance opening 411. When the wiping assembly 2 is in the extended position and the baffle plate 4 moves between the first position and the second position, the connecting shaft 22 moves relative to the baffle plate 4. In the process of the connecting shaft 22 moving relative to the baffle plate 4 to the avoidance opening 411, the connecting shaft 22 contacts the hard sealing plate 4126 at the avoidance opening 411 to generate an extrusion force on the hard sealing plate 4126. The extrusion force can overcome the elastic force of the return spring 4125. At this time, the return spring 4125 is in a compressed state, so that the hard sealing plate 4126 moves toward a position away from the avoidance opening 411 to reduce the blocking area of ​​the avoidance opening 411, so that the connecting shaft 22 can be accommodated in the avoidance opening 411. When the connecting shaft 22 moves out of the avoidance opening 411, the hard sealing plate 4126 is moved to the position of covering the avoidance opening 411 by the elastic restoring force of the return spring 4125 to block the avoidance opening 411.

[0132] Reference Figure 15-17 The hard sealing sheet 4126 is formed with a first guide side edge 4127 and a second guide side edge 4128 on opposite sides along the movement direction of the shielding plate 4, respectively. The first guide side edge 4127 and the second guide side edge 4128 intersect the movement direction of the shielding plate 4 and the movement direction of the hard sealing sheet 4126. The first guide side edge 4127 and the second guide side edge 4128 can guide the connecting shaft 22 during the process of moving into the avoidance opening 411 and the process of moving the connecting shaft 22 out of the avoidance opening 411. The connecting shaft 22 can compress the hard sealing sheet 4126 with a small driving force to move the hard sealing sheet 4126 toward a position away from the avoidance opening 411, thereby allowing the connecting shaft 22 to move into and out of the avoidance opening 411 more smoothly.

[0133] Reference Figure 8 、 Figure 10 and Figure 12 According to some embodiments of the present invention, the avoidance opening 411 includes a first avoidance area 4113 and a second avoidance area 4114 arranged along the extension direction of the avoidance opening 411. The first avoidance area 4113 is provided with a sealing structure 412. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the extended position, the connecting shaft 22 passes through the second avoidance area 4114. When the wiping assembly 2 is in the extended position and the shielding plate 4 is in the first position, the connecting shaft 22 passes through the second avoidance area 4114, exposing the wiping surface 21 to wipe the first working surface. The shielding plate 4 and the wiping assembly 2 can also be closely aligned below the device body 1, preventing interference between the shielding plate 4 and the wiping assembly 2.

[0134] When the wiping assembly 2 is in the extended position and the baffle plate 4 moves between the first position and the second position, the connecting shaft 22 moves relative to the baffle plate 4. When the connecting shaft 22 passes through the first avoidance area 4113 relative to the baffle plate 4, the sealing structure 412 is arranged in the first avoidance area 4113. The first sealing sheet 4121 and the second sealing sheet 4122 can be elastically deformed when they contact the connecting shaft 22. A partial gap can be avoided between the first sealing sheet 4121 and the second sealing sheet 4122 to avoid the connecting shaft 22, so that the connecting shaft 22 can pass through the first avoidance area 4113 smoothly. After the connecting shaft 22 moves out of the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 can rely on their own elasticity to restore to their original state, and the first avoidance area 4113 is sealed by the cooperation of the first sealing sheet 4121 and the second sealing sheet 4122.

[0135] For example, when the cleaning device 100 is cleaning an area outside the second working surface, the wiping component 2 is in the extended position, the baffle 4 is in the first position, and the connecting shaft 22 is passed through the second avoidance area 4114. While facilitating the wiping component 2 to wipe the first working surface, interference between the baffle 4 and the connecting shaft 22 can be avoided, so that the baffle 4 and the wiping component 2 are closely arranged below the device body 1.

[0136] For another example, if the cleaning device 100 is about to run to the second working surface, the driving component 5 drives the shielding plate 4 to move from the first position to the second position. At this time, the connecting shaft 22 moves from the second avoidance area 4114 to the first avoidance area 4113 relative to the shielding plate 4. When the connecting shaft 22 passes through the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 are elastically deformed when contacting the connecting shaft 22, and a part of the gap can be avoided between the first sealing sheet 4121 and the second sealing sheet 4122 to avoid the connecting shaft 22. When the connecting shaft 22 moves out of the first avoidance area After 4113, the first sealing sheet 4121 and the second sealing sheet 4122 can restore to their original shape by relying on their own elasticity. The first sealing sheet 4121 and the second sealing sheet 4122 cooperate to seal the first avoidance area 4113, and the baffle plate 4 moves from the first position to the second position to avoid the lifting space of the wiping component 2. The lifting component drives the wiping component 2 to move upward from the extended position to the retracted position relative to the equipment body 1, and the driving component 5 drives the baffle plate 4 to move from the second position to the first position to effectively block the wiping surface 21, reducing or avoiding the second working surface from being contaminated or wetted by the wiping component 2.

[0137] For another example, if the cleaning device 100 moves from the second working surface area to the first working surface, the driving component 5 drives the shielding plate 4 to move from the first position to the second position to avoid the lifting space of the wiping component 2, and the lifting component drives the wiping component 2 to move downward from the retracted position to the extended position relative to the device body 1, so that the wiping surface 21 can wipe the first working surface; and the driving component 5 drives the shielding plate 4 to move from the second position to the first position. At this time, the connecting shaft 22 moves relative to the shielding plate 4 from the first avoidance area 4113 toward the second avoidance area 4114 moves. When the connecting shaft 22 passes through the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 are elastically deformed when in contact with the connecting shaft 22, and a gap can be left between the first sealing sheet 4121 and the second sealing sheet 4122 to avoid the connecting shaft 22. After the connecting shaft 22 moves out of the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 can rely on their own elasticity to restore to their original state, and the connecting shaft 22 is arranged in the second avoidance area 4114.

[0138] Reference Figure 8 、 Figure 10 and Figure 12According to some embodiments of the present invention, a rib 42 is provided on the outer edge of the shielding plate 4. The rib 42 is located on the upper side of the shielding plate 4 and extends along the circumference of the shielding plate 4. The rib 42 can enhance the structural strength of the shielding plate 4. A certain assembly gap exists between the upper side of the shielding plate 4 and the bottom 11 of the device body 1. The rib 42 can also cover this assembly gap, preventing the assembly gap from being directly exposed to the outside and reducing the entry of dust and other impurities into the space between the shielding plate 4 and the device body through the assembly gap. The rib 42 can also shield the structure between the device body and the shielding plate 4, which is conducive to improving the overall aesthetics of the cleaning device 100.

[0139] For example, when the wiping assembly 2 is in the retracted position and the shielding plate 4 is in the first position, the wiping assembly 2 is located on the side of the shielding plate 4 facing the device body 1. Since the rib 42 is located on the upper side of the shielding plate 4 and extends along the circumference of the shielding plate 4, the shielding effect of the shielding plate 4 on the wiping assembly 2 can be enhanced, thereby improving the aesthetics of the cleaning device 100. In addition, when the wiping assembly 2 is located on the side of the shielding plate 4 facing the device body 1, the shielding plate 4 can receive water falling from the wiping assembly 2. The rib 42 extending along the axial direction of the shielding plate 4 can increase the height of the shielding plate 4 in the circumferential direction, thereby reducing the possibility of water accumulated on the shielding plate 4 flowing directly to the working surface through the outer edge of the shielding plate 4.

[0140] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the shielding plate 4 is slidable between a first position and a second position, both of which are located below the device body 1, and the shielding plate 4 is slidable between the first position and the second position, so that the shielding plate 4 is telescopically arranged at the bottom 11 of the device body 1, and the shielding plate 4 moves between the first position and the second position by sliding. In this way, the driving component 5 for driving the shielding plate 4 to slide has a simple structure and a small volume, and the space required for the shielding plate 4 to move is also small, which is conducive to the layout optimization and miniaturization of the cleaning device 100.

[0141] Reference Figure 9 、 Figure 10 and Figure 12According to some embodiments of the present invention, the drive assembly 5 includes a drive motor 51 and a transmission mechanism 52. The drive motor 51 is mounted on the device body 1. A transmission bar 43 is provided on the shielding plate 4. The transmission bar 43 extends along the sliding direction of the shielding plate 4. The transmission mechanism 52 is connected to the output shaft 511 of the drive motor 51, and the transmission mechanism 52 and the transmission bar 43 can be driven to cooperate with each other to drive the shielding plate 4 to slide. The rotation of the drive motor 51 can drive the transmission mechanism 52 to move, and the movement of the transmission mechanism 52 can drive the transmission bar 43 to move. The transmission bar 43 extends along the sliding direction of the shielding plate 4, and the shielding plate 4 can slide between a first position and a second position. The drive motor 51 can drive the transmission bar 43 to slide between the first position and the second position via the transmission mechanism 52, thereby realizing the process of the drive motor 51 driving the shielding plate 4 to slide between the first position and the second position.

[0142] Reference Figure 10 and Figure 11 According to some embodiments of the present invention, the transmission mechanism 52 is frictionally engaged with the transmission bar 43. The drive motor 51 and the transmission bar 43 are connected by friction. When the drive motor 51 drives the transmission mechanism 52 to move, the friction between the transmission mechanism 52 and the transmission bar 43 drives the transmission bar 43 to move, thereby driving the shielding plate 4 to slide.

[0143] Reference Figure 12 and Figure 13 According to some embodiments of the present invention, the transmission mechanism 52 includes a drive wheel 521 and a guide wheel 522. The drive assembly 5 also includes a drive bracket 53. The drive bracket 53 is mounted on the device body 1. The drive wheel 521 is connected to the output shaft 511 of the drive motor 51 and frictionally engages with the transmission bar 43. The guide wheel 522 is rotatably mounted on the drive bracket 53 and engages with the transmission bar 43. The guide wheel 522 and the drive wheel 521 are located on both sides of the transmission bar 43 in the width direction, and the transmission bar 43 is located in the gap between the guide wheel 522 and the drive wheel 521. The drive wheel 521 is connected to the output shaft 511 of the drive motor 51. When the drive motor 51 is operating, the output shaft 511 can drive the drive wheel 521 to rotate. The drive bracket 53 can support and fix the guide wheel 522.

[0144] By positioning the guide wheels 522 and the driving wheels 521 on both sides of the transmission bar 43 in the width direction, the frictional fit between the driving wheels 521 and the transmission bar 43 and the matching relationship between the guide wheels 522 and the transmission bar 43 can provide a guiding effect on the transmission bar 43, thereby enabling the transmission bar 43 to stably slide between the first position and the second position relative to the device body under the guiding effect; and, by positioning the guide wheels 522 and the driving wheels 521 on both sides of the transmission bar 43 in the width direction, the transmission bar 43 is located in the gap between the guide wheels 522 and the driving wheels 521, and the close fit between the guide wheels 522, the driving wheels 521 and the transmission bar 43 is conducive to improving the guiding accuracy of the transmission bar 43 during the sliding process, avoiding unnecessary displacement of the transmission bar 43, and improving the stability of the baffle 4.

[0145] When the driving motor 51 drives the driving wheel 521 to rotate, the friction between the driving wheel 521 and the transmission bar 43 and the friction between the guide wheel 522 and the transmission bar 43 can be used to drive the transmission bar 43 to slide, thereby driving the baffle 4 to slide stably between the first position and the second position relative to the equipment body.

[0146] For example, the outer peripheral side of the driving wheel 521 and the guide wheel 522 can be made of rubber, which has good elasticity. When the transmission bar 43 is located between the guide wheel 522 and the driving wheel 521, for example, there is a small gap between the transmission bar 43 and the guide wheel 522 or the driving wheel 521, the rubber can fill this gap between the transmission bar 43 and the guide wheel 522 and the transmission bar 43 and the driving wheel 521 to enhance the friction fit effect between the transmission bar 43 and the guide wheel 522 and the transmission bar 43 and the driving wheel 521.

[0147] Reference Figure 12 and Figure 13 According to some embodiments of the present invention, the transmission mechanism 52 is engaged with the transmission bar 43. The drive motor 51 and the transmission bar 43 are connected by the engagement of the transmission mechanism 52 with the transmission bar 43, so that when the drive motor 51 drives the transmission mechanism 52 to move, the transmission bar 43 can be driven to move, thereby driving the shielding plate 4 to slide.

[0148] For example, the transmission bar 43 may be a rack, and the transmission mechanism 52 includes a first transmission wheel 523 and a second transmission wheel 524. The first transmission wheel 523 is connected to the output shaft 511 of the drive motor 51, the first transmission wheel 523 meshes with the second transmission wheel 524, and the second transmission wheel 524 meshes with the transmission bar 43. The drive assembly 5 includes a drive bracket 53, which is mounted on the device body 1 and the drive motor 51 is mounted on the drive bracket 53. The drive bracket 53 can support and fix the drive motor 51. When the drive motor 51 drives the first transmission wheel 523 to rotate, the first transmission wheel 523 can drive the transmission bar 43 via the second transmission wheel 524, thereby driving the shielding plate 4 to slide between the first position and the second position. In other embodiments, the shielding plate can also slide between the first position and the second position using a motor and a pull rope. For example, the shielding plate can slide between the first position and the second position by pulling the rope and rotating the motor in the forward and reverse directions.

[0149] Reference Figure 10 and Figure 12 According to some embodiments of the present invention, a slide rail extending along the direction of movement of the shielding plate 4 is provided on the device body 1, and a mating rod 44 extending along the direction of movement of the shielding plate 4 is provided on the shielding plate 4. The mating rod 44 and the slide rail are slidably engaged in the direction of movement of the shielding plate 4. The mating rod 44 and the slide rail cooperate to guide and limit the movement of the mating rod 44, ensuring that the mating rod 44 moves along a set direction and along a set trajectory, thereby preventing the shielding plate 4 from deflecting during the sliding process.

[0150] Reference Figure 20 、 Figure 22 and Figure 26 According to some embodiments of the present invention, the cleaning device 100 includes a telescopic member 6. The telescopic member 6 has a first end 61 and a second end 62 in the direction of movement of the shielding plate 4. The first end 61 is connected to the device body 1, and the second end 62 is connected to the shielding plate 4. The length of the telescopic member 6 in the direction of movement of the shielding plate 4 is variable. The first end 61 is connected to the device body 1, and the device body 1 can support and fix the telescopic member 6. The second end 62 is connected to the shielding plate 4, and the shielding plate 4 can be connected to the device body 1.

[0151] Reference Figure 26 、 Figure 27 and Figure 30According to some embodiments of the present invention, the telescopic member 6 includes a plurality of sliding rods 63 arranged along the movement direction of the shielding plate 4. Two adjacent sliding rods 63 can slide along the movement direction of the shielding plate 4. Two adjacent sliding rods 63 can slide between a first position and a second position. The telescopic member 6 is connected to the shielding plate 4 through the second end 62. When the two adjacent sliding rods 63 slide between the first position and the second position, the shielding plate 4 can be driven to slide between the first position and the second position.

[0152] Reference Figure 30 According to some embodiments of the present invention, at least one of two adjacent sliding rods 63 is provided with a ball bearing 634, and the two adjacent sliding rods 63 are adapted to contact each other via the ball bearing 634. When the two adjacent sliding rods 63 slide relative to each other, the contact between the two adjacent sliding rods 63 via the ball bearing 634 can reduce the friction force during the relative movement of the two adjacent sliding rods 63, increase the smoothness of the relative movement of the two adjacent sliding rods 63, and thus make the shielding plate 4 slide more smoothly.

[0153] Reference Figure 26 、 Figure 27 and Figure 30 According to some embodiments of the present invention, in the direction from the first end 61 to the second end 62, the levels of the multiple sliding rods 63 increase successively, and the sliding rod 63 with the lower level among the two adjacent sliding rods 63 is provided with a retaining frame 635, and the retaining frame 635 is provided with a ball 634. The sliding rod 63 with the higher level among the two adjacent sliding rods 63 has a mating surface 636 that cooperates with the ball 634, and the mating surface 636 extends along the movement direction of the shielding plate 4. The sliding rod 63 with the higher level among the two adjacent sliding rods 63 is provided with a limiting protrusion 637. In the movement direction of the shielding plate 4, the limiting protrusion 637 is located on the side of the mating surface 636 close to the first end 61. The retainer 635 supports and secures the ball bearings 634. When two adjacent sliding rods 63 move relative to each other, the ball bearings 634 contact the mating surface 636, reducing friction and increasing the relative sliding between the ball bearings 634 and the mating surface 636, thereby ensuring smoother sliding of the shielding plate 4. The limiting protrusion 637 limits the relative sliding between the two adjacent sliding rods 63, ensuring that the two adjacent sliding rods 63 slide along a predetermined direction and trajectory, and preventing one sliding rod 63 from separating from the other during sliding.

[0154] Reference Figure 30, according to some embodiments of the present utility model, the mating surface 636 is formed as an arc concave surface, which can increase the contact area between the ball 634 and the mating surface 636, and further enhance the connection stability between the ball 634 and the mating surface 636, reducing the possibility that the ball 634 separates from the mating surface 636 due to external forces during the relative sliding of two adjacent sliding rods 63.

[0155] Refer to Figure 23 and Figure 30 , according to some embodiments of the present utility model, the telescopic member 6 includes three sliding rods 63. The three sliding rods 63 are respectively the first sliding rod 631, the second sliding rod 632, and the third sliding rod 633 arranged in sequence along the movement direction of the shielding plate 4. The first sliding rod 631 has a first end 61, the third sliding rod 633 has a second end 62, the length of the first sliding rod 631 is S, and the maximum dimension of the wiping assembly 2 in the movement direction of the shielding plate 4 is D. S and D satisfy: 0.4D < S < 1.2D. When the shielding plate 4 is in the first position, the second sliding rod 632 and the third sliding rod 633 are both located inside the first sliding rod 631.

[0156] For example, S can be 0.4D, 0.5D, 0.8D, 1.0D, 1.2D, etc. By making S not less than 0.4D, when the sliding rod 63 drives the shielding plate 4 to move to the second position, it can ensure that the lifting space for the wiping assembly 2 to lift and provided by the shielding plate 4 is large enough, so that the wiping assembly 2 can move within this part of the lifting space, avoiding interference between the shielding plate 4 and the wiping assembly 2; by making S not greater than 1.2D, when the sliding rod 63 drives the shielding plate 4 to move to the first position, it can make the overall structure of the shielding plate 4 and the device main body 1 more compact, reduce the occupation of the external space of the device main body 1 by the shielding plate 4, and reduce or avoid the shielding plate 4 occupying too much external space of the device main body 1 due to the excessive length S of the first sliding rod 631.

[0157] By 0.4D < S < 1.2D, when the shielding plate 4 is in the second position, it can ensure that the lifting space for the wiping assembly 2 to lift and provided by the shielding plate 4 is large enough, so that the wiping assembly 2 can move within this part of the lifting space; when the shielding plate 4 is in the first position, it can make the overall structure of the shielding plate 4 and the device main body 1 more compact.

[0158] In addition, a sliding rod end cap 638 is provided at the first end of the first sliding rod 631, and a fixing frame 635 and a ball bearing 634 are installed on each of the second sliding rod 632 and the third sliding rod 633. The assembly process between the first sliding rod 631, the second sliding rod 632, and the third sliding rod 634 can be as follows: the retaining frame 635 and the ball bearing 634 are installed on the third sliding rod 633, and then the third sliding rod 633, the retaining frame 635, and the ball bearing 634 are installed in the second sliding rod 632, and then the fixing frame 635 and the ball bearing 634 are installed on the second sliding rod 632, and then the second sliding rod 632, the fixing frame 635 and the ball bearing 634 on the second sliding rod 632, and the third sliding rod 633, the fixing frame 635 and the ball bearing 634 on the third sliding rod 633 are all installed in the first sliding rod 631, and finally the sliding rod end cap 638 is installed on the first end 61 of the first sliding rod 631.

[0159] For example, the sliding rod end cover 638 and the first sliding rod 631 can be connected by snapping, so that the connection between the sliding rod end cover 638 and the first sliding rod 631 is simple and has strong stability.

[0160] Reference Figure 34-36 According to some embodiments of the present invention, the telescopic member 6 includes a connecting rod telescopic mechanism 64, which includes a plurality of hinged connecting rods 641. The plurality of hinged connecting rods 641 form the connecting rod telescopic mechanism 64, and the shielding plate 4 can be moved between the first position and the second position by changing the length and angle of the connecting rod telescopic mechanism 64.

[0161] Reference Figure 36-Figure 39 According to some embodiments of the present invention, the plurality of connecting rods 641 are divided into a plurality of connecting rod groups 642. The plurality of connecting rod groups 642 are arranged along the direction of movement of the shielding plate 4. Each connecting rod group 642 includes two connecting rods 641 that intersect and are hingedly connected. The two connecting rods 641 of two adjacent connecting rod groups 642 are hingedly connected. In this way, the shielding plate 4 can be driven to move by changing the length and angle between the two connecting rods 641 in each connecting rod group 642, or by changing the length and angle between the two connecting rods 641 in two adjacent connecting rod groups 642. Alternatively, the shielding plate 4 can be driven to move between the first position and the second position by changing the length and angle between the two connecting rods 641 in each connecting rod group 642, or by changing the length and angle between the two connecting rods 641 in two adjacent connecting rod groups 642.

[0162] Reference Figure 23 and Figure 31, according to some embodiments of the present utility model, the maximum stroke of the shielding plate 4 is L, and the maximum dimension of the wiping component 2 in the moving direction of the shielding plate 4 is D, where L and D satisfy: D < L < 1.4D. For example, L can be D, 1.1D, 1.2D, 1.3D, 1.4D, etc. By making L not less than D, when the shielding plate 4 moves to the second position, it can ensure that the lifting space for the wiping component 2 to lift and lower避让出 by the shielding plate 4 is large enough, so that the wiping component 2 can move within this part of the lifting space, avoiding interference between the shielding plate 4 and the wiping component 2; by making L not greater than 1.4D, when the shielding plate 4 is in the first position, it can make the overall structure of the shielding plate 4 and the equipment main body 1 more compact, reducing the occupation of the external space of the equipment main body 1 by the shielding plate 4.

[0163] By D < L < 1.4D, when the shielding plate 4 is in the second position, it can ensure that the lifting space for the wiping component 2 to lift and lower避让出 by the shielding plate 4 is large enough, so that the wiping component 2 can move within this part of the lifting space; when the shielding plate 4 is in the first position, it can make the overall structure of the shielding plate 4 and the equipment main body 1 more compact.

[0164] In other embodiments of the present utility model, a separate driving component 5 may not be provided. As Figure 3 shown, the cleaning device 100 further includes a walking wheel component. Among them, the walking wheel component may include a driving motor 51 and a walking wheel 7. By increasing the output on the driving motor 51 of the walking wheel component, the driving motor 51 of the walking wheel component is used to drive the shielding plate 4 to move between the first position and the second position.

[0165] Next, refer to Figures 1-11 to describe the cleaning device 100 according to some embodiments of the present utility model.

[0166] Refer to Figure 2 , Figure 4 and Figure 8 , in this embodiment, the cleaning device 100 includes an equipment main body 1, a wiping component 2, a lifting component, a shielding plate 4, and a driving component 5.

[0167] The wiping component 2 is disposed at the bottom 11 of the equipment main body 1 and the wiping component 2 has a wiping surface 21. The lifting component is installed on the equipment main body 1 and is connected to the wiping component 2, and is used to drive the wiping component 2 to be liftable between an extended position and a retracted position, and the retracted position is higher than the extended position. The shielding plate 4 has a first position and a second position, and the shielding plate 4 is slidable between the first position and the second position. The driving component 5 is disposed on the equipment main body 1 and is connected to the shielding plate 4, and is used to drive the shielding plate 4 to move between the first position and the second position.

[0168] When the shielding plate 4 is in the first position and the wiping assembly 2 is in the extended position, the wiping surface 21 is exposed. When the shielding plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the shielding plate 4 blocks the wiping surface 21. When the shielding plate 4 is in the second position, the shielding plate 4 is used to avoid the lifting space of the wiping assembly 2. Both the first and second positions are located below the device body 1. The device body 1 is provided with a slide rail extending in the direction of movement of the shielding plate 4. The shielding plate 4 is provided with a mating rod 44 extending in the direction of movement of the shielding plate 4. The mating rod 44 slidably engages with the slide rail along the direction of movement of the shielding plate 4.

[0169] The lifting assembly is connected to the wiping assembly 2 via a connecting shaft 22. The shielding plate 4 is provided with an avoidance structure 41 for avoiding the connecting shaft 22. The avoidance structure 41 includes an avoidance opening 411 and a sealing structure 412 provided on the shielding plate 4. The avoidance opening 411 extends in the arrangement direction of the first position and the second position. The sealing structure 412 includes a first sealing sheet 4121 and a second sealing sheet 4122. The avoidance opening 411 includes a first side wall 4111 and a second side wall 4112 arranged opposite each other along the width direction of the avoidance opening 411. The first sealing sheet 4121 is fixed to the first side wall 4111, and the second sealing sheet 4122 is fixed to the second side wall 4112. The first sealing sheet 4121 and the second sealing sheet 4122 cooperate to seal at least a portion of the avoidance opening 411.

[0170] The avoidance opening 411 includes a first avoidance area 4113 and a second avoidance area 4114 arranged along the extension direction of the avoidance opening 411. The sealing structure 412 is arranged in the first avoidance area 4113. When the baffle plate 4 is in the first position and the wiping assembly 2 is in the extended position, the connecting shaft 22 is passed through the second avoidance area 4114.

[0171] There are multiple first sealing sheets 4121 and multiple second sealing sheets 4122 . Both the first sealing sheets 4121 and the second sealing sheets 4122 are tooth-shaped. The first sealing sheets 4121 and the second sealing sheets 4122 are alternately arranged in the extending direction of the avoidance opening 411 .

[0172] The driving assembly 5 includes a driving motor 51, a transmission mechanism 52 and a driving bracket 53. The driving motor 51 is installed on the equipment body 1. A transmission bar 43 is provided on the baffle 4. The transmission bar 43 extends along the sliding direction of the baffle 4. The transmission mechanism 52 is connected to the output shaft 511 of the driving motor 51 and can be transmitted and cooperated with the transmission bar 43 to drive the baffle 4 to slide.

[0173] The transmission mechanism 52 includes a drive wheel 521 and a guide wheel 522. The drive bracket 53 is mounted on the device body 1. The drive wheel 521 is connected to the output shaft 511 of the drive motor 51 and frictionally engages with the transmission bar 43. The guide wheel 522 is rotatably mounted on the drive bracket 53 and engages with the transmission bar 43. The guide wheel 522 and the drive wheel 521 are located on opposite sides of the transmission bar 43 in the width direction, and the transmission bar 43 is located in the gap between the guide wheel 522 and the drive wheel 521. When the drive motor 51 drives the drive wheel 521 to rotate, the friction between the drive wheel 521 and the transmission bar 43, as well as the friction between the guide wheel 522 and the transmission bar 43, can drive the transmission bar 43 to slide, thereby driving the shielding plate 4 to stably slide between the first position and the second position relative to the device body.

[0174] For example, when the cleaning device 100 is cleaning an area outside the second working surface, the wiping component 2 is in the extended position, the baffle plate 4 is in the first position, and the connecting shaft 22 passes through the second avoidance area 4114. While facilitating the wiping component 2 to wipe the first working surface, interference between the baffle plate 4 and the connecting shaft 22 can be avoided, so that the baffle plate 4 and the wiping component 2 are closely arranged below the device body 1.

[0175] For another example, if the cleaning device 100 is about to run to the second working surface, the driving motor 51 drives the transmission bar 43 to move via the driving wheel 521 and the guide wheel 522 to drive the baffle 4 to move from the first position to the second position. At this time, the connecting shaft 22 moves from the second avoidance area 4114 to the first avoidance area 4113 relative to the baffle 4. When the connecting shaft 22 passes through the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 are elastically deformed when contacting the connecting shaft 22, and a partial gap can be avoided between the first sealing sheet 4121 and the second sealing sheet 4122 to avoid the connecting shaft 22. After the connecting shaft 22 moves out of the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 can rely on their own elasticity to restore to their original state. The first avoidance area 4113 is sealed by the cooperation of the first sealing sheet 4121 and the second sealing sheet 4122, and the baffle plate 4 moves from the first position to the second position, which can avoid the lifting space of the wiping component 2. The lifting component drives the wiping component 2 to move upward from the extended position to the retracted position relative to the equipment body 1, and the driving component 5 drives the baffle plate 4 from the second position to the first position to effectively block the wiping surface 21, reducing or avoiding the second working surface from being contaminated or wetted by the wiping component 2.

[0176] For another example, if the cleaning device 100 moves from the second working surface area to the first working surface, the driving motor 51 drives the transmission bar 43 to move via the driving wheel 521 and the guide wheel 522 to drive the shielding plate 4 to move from the first position to the second position to avoid the lifting space of the wiping component 2. The lifting component drives the wiping component 2 to move downward from the retracted position to the extended position relative to the device body 1, so that the wiping surface 21 can wipe the first working surface; and the driving motor 51 drives the transmission bar 43 to move via the driving wheel 521 and the guide wheel 522 to drive the shielding plate 4 to move from the second position to the first position. At this time, the connecting shaft 22 Relative to the movement of the baffle plate 4 from the first avoidance area 4113 toward the second avoidance area 4114, when the connecting shaft 22 passes through the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 are elastically deformed when contacting the connecting shaft 22, and a partial gap can be avoided between the first sealing sheet 4121 and the second sealing sheet 4122 to avoid the connecting shaft 22. After the connecting shaft 22 moves out of the first avoidance area 4113, the first sealing sheet 4121 and the second sealing sheet 4122 can rely on their own elasticity to restore to their original state, and the connecting shaft 22 is arranged in the second avoidance area 4114.

[0177] Next, we will refer to Figure 12 and Figure 13 The cleaning device 100 of another embodiment of the present invention is described.

The drive assembly 5 includes a drive bracket 53, which is mounted on the device body 1, and the drive motor 51 is mounted on the drive bracket 53. The drive bracket 53 can support and fix the drive motor 51. When the drive motor 51 drives the first transmission wheel 523 to rotate, the first transmission wheel 523 can drive the transmission bar 43 to move via the second transmission wheel 524, so as to drive the shielding plate 4 to slide between the first position and the second position.
