[0061] 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.

[0062] Reference below Figures 1-15 A cleaning device 100 according to an embodiment of the present invention is described.

[0063] Reference Figure 2-Figure 4According to the embodiment of the first aspect of the present utility model, the cleaning device 100 includes a device body 1, a wiping assembly 2, a baffle 3 and a driving assembly 4. The wiping assembly 2 is arranged at the bottom 17 of the device body 1 and the wiping assembly 2 has a wiping surface 21. The baffle 3 has a first position and a second position. The driving assembly 4 is arranged on the device body 1 and the driving assembly 4 is connected to the baffle 3. The driving assembly 4 is used to drive the baffle 3 to move between the first position and the second position to cover or expose the wiping surface 21. 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 parts. The device body 1 plays a role of bearing and protecting other components of the cleaning device 100, wherein the other components include the wiping assembly 2, the baffle 3 and the driving assembly 4, but are not limited to this.

[0064] The driving assembly 4 is connected to the shielding plate 3 and is used to drive the shielding plate 3 to move to expose the wiping surface 21 or shield the wiping surface 21. Whether to expose the wiping surface 21 or shield the wiping surface 21 can be determined according to the surface to be worked on.

[0065] 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. If the material of the surface to be worked is suitable for wiping by the wiping component 2, the driving component 4 drives the shielding plate 3 to move to expose the wiping surface 21. If the material of the surface to be worked is not suitable for wiping by the wiping component 2, the driving component 4 drives the shielding plate 3 to move to block the wiping surface 21.

[0066] 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 4 drives the shielding plate 3 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 4 drives the shielding plate 3 to move to block the wiping surface 21.

[0067] 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.

[0068] 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.

[0069] For example, the movement process of the shielding plate 3 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 shielding plate 3 is located in the first position; if the cleaning device 100 is about to run to the second working surface area, the driving component 4 drives the shielding plate 3 to move from the first position to the second position; if the cleaning device 100 runs from the second working surface area to the first working surface, the driving component 4 drives the shielding plate 3 to move from the second position to the first position.

[0070] 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 wiping component 2 can be controlled to rise, and the driving component 4 drives the baffle 3 to move to the side of the wiping component 2 facing the first working surface to block the wiping surface 21, so that when the cleaning device 100 runs to the second working surface, the baffle 3 blocks the wiping surface 21 and the second working surface, and the wiping surface 21 does not contact the second working surface, thereby effectively preventing the second working surface from being contaminated or wetted by the wiping surface 21; when the cleaning device 100 runs from the second working surface to the first working surface, the driving component 4 drives the baffle 3 to move to expose the wiping surface 21, so that the wiping surface 21 contacts the first working surface to wipe the first working surface.

[0071] By arranging the wiping component 2 in a liftable manner at the bottom 17 of the device body 1, arranging the driving component 4 on the device body 1 and connecting the driving component 4 to the baffle 3, the driving component 4 can drive the baffle 3 to move to expose the wiping surface 21, so that the wiping surface 21 contacts the first working surface to wipe the first working surface. The driving component 4 can also drive the baffle 3 to move to cover the wiping surface 21, so that when the cleaning device 100 runs to the second working surface, 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.

[0072] 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.

[0073] 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.

[0074] The shielding plate 3 can adopt a variety of shapes and sizes, such as square, rectangular, polygonal, circular, and elliptical. The shape of the shielding plate 3 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 3 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 3 are not limited, as long as the shielding plate 3 ensures that when the cleaning device 100 moves to the second working surface, the wiper will not come into contact with the second working surface.

[0075] 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 a 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 may be dripped into the wiper or sprayed onto the work surface and then wiped away by the wiper.

[0076] 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 cleaning base station and clean the wiping member through the cleaning 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.

[0077] In some embodiments, the cleaning device 100 further includes a controller and a second detection component. The second detection component and the drive component 4 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 material in the surrounding environment of the cleaning device 100. The detection object may include whether the surrounding environment includes a second working surface or other materials that are not suitable for wiping. 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 block 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.

[0078] 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.

[0079] If the cleaning device 100 is detected to have a second working surface within a first preset distance in the direction of travel, it indicates that the cleaning device 100 is about to reach the second working surface area. The first 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 second working surface, or the first preset distance can be the distance between the edge of the wiping assembly 2 on the side closest to the second working surface and the edge of the second working surface. When the second detection assembly detects that the cleaning device 100 is about to move or has already moved to the second working surface, the controller drives the wiping assembly 2 to rise in response to a signal from the second detection assembly, and activates the drive assembly 4 to drive the shielding plate 3 to shield the wiping surface 21.

[0080] If the cleaning device 100 is detected to be within a second preset distance in the direction of travel of the cleaning device 100, 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, the controller activates the drive assembly 4 in response to a signal from the second detection assembly, thereby driving the shielding plate 3 to expose the wiping surface 21 and driving the wiping assembly 2 to descend.

[0081] According to the cleaning device 100 of the embodiment of the present invention, the driving component 4 is arranged on the device body 1 and the driving component 4 is connected to the baffle 3, so that the driving component 4 can drive the baffle 3 to move to expose the wiping surface 21, so that the wiping surface 21 contacts the first working surface to wipe the first working surface; and the driving component 4 can also drive the baffle 3 to move to block the wiping surface 21, so as to effectively isolate the wiping surface 21 from the second working surface, thereby effectively preventing the wiping surface 21 from contaminating the second working surface. For example, when the cleaning device 100 runs to the second working surface, the baffle 3 blocks the wiping surface 21 to prevent the wiping surface 21 from contacting the second working surface, thereby effectively preventing the second working surface from being contaminated or wetted by the wiping surface 21.

[0082] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the first position is where the shielding plate 3 exposes the wiping surface 21, and the second position is where the shielding plate 3 blocks the wiping surface 21. The first position is higher than the second position. For example, the first position can be any position that exposes the wiping surface 21. When the shielding plate 3 is in the first position, the shielding plate 3 is positioned above the wiping assembly 2 to ensure that the wiping surface 21 is exposed.

[0083] Optionally, according to the normal operating direction of the cleaning device 100, the device body 1 further includes a front portion 14, a rear portion 15 and a top portion 16, wherein the front portion 14 and the rear portion 15 are relatively arranged in the front-to-back direction (for example, refer to Figure 1 The shielding plate 3 is disposed opposite to the wiping assembly 2 in the direction e1 in the figure, and the top 16 and bottom 17 are disposed opposite to each other in the vertical direction. When the shielding plate 3 is in the first position, the wiping surface 21 is exposed. The first position can be located at the front 14, rear 15, or top 16 of the device body 1. It is only necessary to ensure that the shielding plate 3 is located above the wiping assembly 2 when in the first position to ensure that the wiping surface 21 is exposed.

[0084] Optionally, when the shielding plate 3 is in the second position, the projection of the wiping surface 21 on the shielding plate 3 falls completely or partially on the shielding plate 3, so that the shielding plate 3 can completely or partially cover the wiping surface 21, which is beneficial to improving the shielding effect of the shielding plate 3.

[0085] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the first position is located at the top 16 of the device body 1, and the second position is located at the bottom 17 of the device body 1. When the shielding plate 3 is in the first position, the first position is located at the top 16 of the device body 1. This ensures that the wiping surface 21 is exposed when the shielding plate 3 is in the first position, so that the wiping assembly 2 can wipe the first working surface. In addition, because the shielding plate 3 is located at the top 16 of the device body 1 when the cleaning device 100 is cleaning the first working surface, it can prevent the shielding plate 3 from interfering with objects in the cleaning area. When the shielding plate 3 is in the second position, the second position is located at the bottom 17 of the device body 1, so that the shielding plate 3 can block the wiping surface 21. The projection of the wiping surface 21 on the shielding plate 3 completely or partially falls on the shielding plate 3. When the cleaning device 100 moves to the second working surface, the wiping surface 21 does not contact the second working surface, thereby effectively preventing the second working surface from being contaminated or wetted by the wiping surface 21.

[0086] For example, the movement process of the baffle 3 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 3 is located at the top 16 of the device body 1; if the cleaning device 100 is about to run to the second working surface area, the driving component 4 drives the baffle 3 to move from the first position to the second position, that is, the driving component 4 drives the baffle 3 to rotate from the top 16 of the device body 1 to the bottom 17 of the device body 1; if the cleaning device 100 runs from the second working surface area to the first working surface, the driving component 4 drives the baffle 3 to move from the second position to the first position, that is, the driving component 4 drives the baffle 3 to rotate from the bottom 17 of the device body 1 to the top 16 of the device body 1, so that the wiping component 2 can wipe the first working surface.

[0087] Reference Figure 14 and Figure 15 According to some embodiments of the present invention, a first groove 11 is formed on the bottom 17 of the device body 1. The first groove 11 is used to accommodate the wiping assembly 2 or the wiping assembly 2 and the shielding plate 3. By forming the first groove 11 on the bottom 17 of the device body 1, the wiping assembly 2 or the wiping assembly 2 and the shielding plate 3 can be accommodated in the first groove 11, so that there is a sufficient distance between the wiping assembly 2 and the surface to be worked on. This ensures that after the shielding plate 3 moves to the second position, it will not rub against the surface to be worked on.

[0088] Reference Figure 2 According to some embodiments of the present invention, a second groove 18 is formed on the top 16 of the device body 1. The second groove 18 is used to accommodate the shielding plate 3. By forming the second groove 18 on the top 16 of the device body 1, the shielding plate 3 can be accommodated in the second groove 18 when it is in the first position, so that the shielding plate 3 can be accommodated in the device body 1, achieving an embedded effect of the shielding plate 3 and improving the aesthetics.

[0089] In some embodiments, a second groove 18 is formed at the bottom 17 of the device body 1, and the baffle plate 3 can be accommodated in the second groove 18 when it is in the first position. For example, the baffle plate 3 can be accommodated in the second groove 18 and the baffle plate 3 is located between the device body 1 and the wiping assembly 2. The space under the device body 1 can be fully utilized, so that the overall structure of the baffle plate and the device body 1 is more compact, and the occupation of the external space of the device body 1 by the baffle plate 3 can be reduced, which is conducive to the miniaturization of the cleaning device 100 and facilitates the transportation and storage of the cleaning device 100.

[0090] Reference Figure 12 、 Figure 14 and Figure 15According to some embodiments of the present invention, a first groove 11 is formed on the bottom 17 of the device body 1. The first groove 11 is used to accommodate the wiping assembly 2 or the wiping assembly 2 and the shielding plate 3. Furthermore, a second groove 18 is formed on the top 16 of the device body 1. The second groove 18 is used to accommodate the shielding plate 3. By forming the first groove 11 on the bottom 17 of the device body 1, the wiping assembly 2 or the wiping assembly 2 and the shielding plate 3 can be accommodated in the first groove 11, so that there is a sufficient distance between the wiping assembly 2 and the work surface, ensuring that the shielding plate 3 does not rub against the work surface after moving to the second position. Furthermore, by forming the second groove 18 on the top 16 of the device body 1, the shielding plate 3 can be accommodated in the second groove 18 when in the first position, thereby allowing the shielding plate 3 to be accommodated in the device body 1, achieving an embedded effect of the shielding plate 3 and improving the aesthetics.

[0091] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the projection of the shielding plate 3 along the vertical direction when it is in the first position and the projection of the shielding plate 3 along the vertical direction when it is in the second position at least partially overlap, which can reduce the space occupied by the shielding plate 3 in the horizontal direction outside the device body 1 when the shielding plate 3 is in the first position or the shielding plate 3 is in the second position, so that the structure of the shielding plate 3 and the device body 1 can be compact when the shielding plate 3 is in the first position or the second position.

[0092] Among them, the projection of the shielding plate 3 along the vertical direction when it is in the first position and the projection of the shielding plate 3 along the vertical direction when it is in the second position at least partially overlap, which may include the following situations: for example, the projection of the shielding plate 3 along the vertical direction when it is in the first position and the projection of the shielding plate 3 along the vertical direction when it is in the second position may completely overlap; for another example, the projection of the shielding plate 3 along the vertical direction when it is in the first position and the projection of the shielding plate 3 along the vertical direction when it is in the second position may partially overlap.

[0093] Reference Figure 2 、 Figure 4 and Figure 5 According to some embodiments of the present invention, the wiping assembly 2 is located at the rear of the device body 1, the shielding plate 3 has a first side 31 and a second side 32 arranged opposite to each other in the front-to-back direction, the first side 31 is located behind the second side 32, and the driving assembly 4 is connected to the second side 32 of the shielding plate 3. For example, the device body 1 has a left-right direction (for example, refer to Figure 1The first side portion 12 and the second side portion 13 are relatively arranged (in the e2 direction), the left and right directions intersect with the vertical direction, the first side 31 is closer to the rear edge of the device body 1 than the second side 32, and is connected to the second side 32 of the baffle plate 3 through the driving component 4. While the driving component 4 drives the baffle plate 3 to move between the first position and the second position, the driving component 4 can fit with the first side portion 12 or the second side portion 13 of the device body 1, so that the overall structure of the driving component 4 and the device body 1 is compact, and the driving component 4 can avoid interference with the objects in the cleaning area and the baffle plate 3 during the switching of the baffle plate 3 between the first position and the second position.

[0094] In some embodiments of the present invention, the wiping assembly 2 is located at the rear of the device body 1, and accordingly the baffle plate 3 can also be closer to the rear of the device body 1. For example, when the baffle plate 3 is in the second position, the baffle plate 3 is also located at the rear of the device body 1. By connecting the front side of the baffle plate 3 to the driving assembly 4, the rear side of the baffle plate 3 is a free end, so that the baffle plate 3 can move toward the rear and upper part to facilitate the exposure of the wiping surface 21; and, by the first side 31 being located at the rear side of the second side 32, the driving assembly 4 is connected to the second side 32 of the baffle plate 3. In the process of realizing the driving assembly 4 driving the baffle plate 3 to move between the first position and the second position, the driving assembly 4 can be prevented from interfering with the objects in the cleaning area and the baffle plate 3 during the switching of the baffle plate 3 between the first position and the second position.

[0095] Optionally, the device body 1 also includes a front 14, a rear 15 and a top 16, wherein the front 14 and the rear 15 are arranged opposite to each other in the front-to-back direction, and the top 16 and the bottom 17 are arranged opposite to each other in the vertical direction, and the first side 31 of the baffle 3 can face the rear 15 of the device body 1. Of course, the first side 31 of the baffle 3 can also face the front 14 of the device body 1.

[0096] Reference Figure 12-14 According to some embodiments of the present invention, at least one roller 33 is provided on the first side 31 of the shielding plate 3. By rotatably connecting the roller 33 to the first side 31, the roller 33 can slide on the surface of the device body 1 when the shielding plate 3 switches between the first position and the second position, thereby preventing friction between the shielding plate 3 and the surface of the device body 1.

[0097] Optionally, the shielding plate 3 includes a first surface 34 and a second surface 35 disposed opposite each other. When the shielding plate 3 is in the first position, the first surface 34 is located on the side of the shielding plate 3 facing away from the top 16, and the second surface 35 is located on the side of the shielding plate 3 facing the top 16. When the shielding plate 3 is in the second position, the first surface 34 is located on the side of the shielding plate 3 facing the wiping surface 21. In some embodiments, the roller 33 is rotatably connected to the edge of the first side 31 facing away from the second side 32 and is disposed through the first surface 34 and the second surface 35. This not only prevents friction between the shielding plate 3 and the surface of the device body 1, but also prevents friction between the shielding plate 3 and the surface to be worked on.

[0098] In some embodiments, the specific number of rollers 33 is not limited to the above number. For example, the number of rollers 33 can be 2, 4, 5, 7, 8, 10, etc., but is not limited thereto.

[0099] Reference Figure 7 and Figure 8 According to some embodiments of the present invention, the drive assembly 4 includes a drive mechanism 41, a transmission assembly 43, and a connecting rod 46. The transmission assembly 43 is connected to the drive mechanism 41. The connecting rod 46 has a first end 461 and a second end 462. The first end 461 is connected to the shielding plate 3, and the second end 462 is connected to the transmission assembly 43. The first end 461 of the connecting rod 46 can be disposed on a side of the shielding plate 3 near the transmission assembly 43. This not only enables the drive mechanism 41 to drive the connecting rod 46 via the transmission assembly 43 to move, thereby driving the shielding plate 3 to switch between the first position and the second position, but also ensures that the connecting rod 46 does not interfere with the shielding plate 3 during the switching process between the first position and the second position.

[0100] Optionally, the first end 461 of the connecting rod 46 may also be arranged on the side of the shielding plate 3 facing away from or toward the device body 1 .

[0101] Reference Figure 8 、 Figure 10 and Figure 11 According to some embodiments of the present invention, the transmission assembly 43 includes a conveyor belt 431 and a transmission wheel assembly 43c. The driving mechanism 41 is connected to the transmission wheel assembly 43c to drive the transmission wheel assembly 43c to move. The transmission wheel assembly 43c cooperates with the conveyor belt 431 to drive the conveyor belt 431 to move. The second end 462 is connected to the conveyor belt 431. The second end 462 can be disposed on the side of the conveyor belt 431 away from the transmission wheel assembly 43c to prevent interference between the connecting rod 46 and the transmission wheel assembly 43c. Of course, the second end 462 can also be disposed on the side of the conveyor belt 431, as long as the connecting rod 46 does not interfere with the transmission wheel assembly 43c.

[0102] By connecting the second end 462 of the connecting rod 46 to the conveyor belt 431 , the shielding plate 3 can be switched between the first position and the second position under the drive of the conveyor belt 431 , thereby realizing the movement of the shielding plate 3 by means of transmission by the conveyor belt 431 .

[0103] Reference Figures 8-10 According to some embodiments of the present invention, the second end 462 is detachably connected to the conveyor belt 431, which can facilitate maintenance or replacement of the connecting rod 46 or the conveyor belt 431. For example, the conveyor belt 431 is provided with a latching hole 450, and the second end 462 is provided with a latching protrusion. The latching protrusion is latched into the latching hole 450, and the second end 462 is latched and connected to the conveyor belt 431. This can achieve a detachable connection between the second end 462 of the connecting rod 46 and the conveyor belt 431, and can also make the connection between the second section 4512 of the connecting rod 46 and the conveyor belt 431 simple and have strong stability.

[0104] Reference Figure 7 、 Figure 11 and Figure 13 According to some embodiments of the present invention, the transmission wheel assembly 43c includes a first transmission wheel 437 and a second transmission wheel 438. The first transmission wheel 437 and the second transmission wheel 438 are arranged in a front-to-back direction (for example, refer to Figure 1 The conveyor belt 431 is spaced apart from each other in the direction e1 in the figure. The conveyor belt 431 is sleeved on the first transmission wheel 437 and the second transmission wheel 438. The driving mechanism 41 is connected to the first transmission wheel 437 and / or the second transmission wheel 438. It can be understood that the driving mechanism 41 can be connected to the first transmission wheel 437. In this case, the first transmission wheel 437 is the driving wheel and the second transmission wheel 438 is the driven wheel. The driving mechanism 41 is used to drive the first transmission wheel 437 to rotate, thereby driving the second transmission wheel 438 and the conveyor belt 431 to move; or the driving mechanism 41 can be connected to the second transmission wheel 438. In this case, the second transmission wheel 438 is the driving wheel and the first transmission wheel 437 is the driven wheel. The driving member is used to drive the second transmission wheel 438 to rotate, thereby driving the first transmission wheel 437 and the conveyor belt 431 to move; or the driving mechanism 41 can also be connected to the first transmission wheel 437 and the second transmission wheel 438. The driving mechanism 41 is used to drive the first transmission wheel 437 and the second transmission wheel 438 to rotate, thereby driving the conveyor belt 431 to rotate.

[0105] Reference Figure 7 and Figure 11In some embodiments, the conveyor belt 431 can be meshed with the first transmission wheel 437 and the second transmission wheel 438. For example, the surface of the conveyor belt 431 facing the transmission wheel assembly 43c is formed with alternating protruding teeth and tooth grooves. The surfaces of the first transmission wheel 437 and the second transmission wheel 438 facing the conveyor belt 431 are also formed with alternating protruding teeth and tooth grooves. The tooth grooves of the first transmission wheel 437 and the second transmission wheel 438 mesh with the protruding teeth of the conveyor belt 431. The transmission wheel assembly 43c and the conveyor belt 431 are transmission-connected by the meshing of the protruding teeth and tooth grooves, so that when the driving mechanism 41 drives at least one of the first transmission wheel 437 and the second transmission wheel 438 to rotate, the conveyor belt 431 can be driven to move.

[0106] Reference Figure 7 and Figure 11 In some embodiments, the conveyor belt 431 can be frictionally connected to the first transmission wheel 437 and the second transmission wheel 438. The surface of the conveyor belt 431 facing the transmission wheel assembly 43c is closely attached to the first transmission wheel 437 and the second transmission wheel 438. When the driving mechanism 41 drives at least one of the first transmission wheel 437 and the second transmission wheel 438 to rotate, the friction between the first transmission wheel 437 and the conveyor belt 431 and the friction between the second transmission wheel 438 and the conveyor belt 431 can be used to drive the conveyor belt 431 to move.

[0107] Reference Figure 7 and Figure 11 In some embodiments, the conveyor belt 431 may be a rack, and the first transmission wheel 437 and the second transmission wheel 438 may be gears. The conveyor belt 431, the first transmission wheel 437, and the second transmission wheel 438 constitute a rack-and-pinion mechanism. The transmission wheel assembly 43c is connected to the conveyor belt 431 via a gear-and-rack meshing mechanism, enabling the conveyor belt 431 to move when a driver drives at least one of the first transmission wheel 437 and the second transmission wheel 438 to rotate.

[0108] Reference Figure 13-15According to some embodiments of the present invention, the transmission assembly 43 further includes a mounting plate 441, which is disposed on the device body 1. The mounting plate 441 is formed with a track 451, at least a portion of which is disposed around the conveyor belt 431. The second end 462 is provided with a first mounting portion 463 and a sliding portion 464, the first mounting portion 463 being connected to the conveyor belt 431, and the sliding portion 464 being slidably disposed on the track 451. The sliding portion 464 is slidably disposed on the track 451, that is, the sliding portion 464 can extend into the track 451. When the driving mechanism 41 drives the conveyor belt 431 and the shielding plate 3 to move, the sliding portion 464 can slide along the track 451. The sliding portion 464 can be integrally formed with the connecting rod 46, or be disposed on the connecting rod 46 by riveting, welding, bonding, bolting, pin-key connection, snap-fit ​​connection, or magnetic adsorption connection.

[0109] An angle is formed between the first mounting portion 463 and the sliding portion 464, so that the first mounting portion 463 can be set on the conveyor belt 431, and the sliding portion 464 can be slidably set in the track 451, and the first mounting portion 463 and the sliding portion 464 can move along their respective tracks under the drive of the conveyor belt 431 without interfering with each other.

[0110] Among them, at least part of the track 451 is arranged around the conveyor belt 431, which may include the following situations: for example, part of the track 451 may be arranged around the conveyor belt 431; for another example, all of the track 451 may be arranged around the conveyor belt 431.

[0111] For example, refer to Figure 13-15 The first mounting portion 463 is snap-connected with the conveyor belt 431. A snap-connecting protrusion is provided on the first mounting portion 463, and a snap-connecting hole 450 is provided on the conveyor belt 431, so that the first mounting portion 463 and the conveyor belt 431 can be detachably connected, which is convenient for the maintenance or replacement of the connecting rod 46 or the conveyor belt 431. The snap-connection between the first mounting portion 463 and the conveyor belt 431 can also make the connection between the first mounting portion 463 and the conveyor belt 431 simple and have strong stability.

[0112] For example, refer to Figure 13-15 The first mounting portion 463 and the conveyor belt 431 may also be fixedly connected together by riveting, bolting, pinning, or magnetic adsorption. Of course, the first mounting portion 463 and the conveyor belt 431 may be connected in a non-detachable manner, for example, by welding, gluing, or other methods.

[0113] By setting a track 451, and providing a first mounting portion 463 and a sliding portion 464 at the second end 462, wherein the first mounting portion 463 is connected to the side of the conveyor belt 431 away from the transmission wheel assembly 43c, and the sliding portion 464 can extend into the track 451 and can slide along the track 451. On the one hand, when the conveyor belt 431 drives the baffle plate 3 to move, the baffle plate 3 can move smoothly, thereby reducing the power required by the driving mechanism 41, which can achieve the purpose of reducing the energy consumption of the driving mechanism 41, making the driving mechanism 41 not easily damaged, and ensuring the service life of the driving mechanism 41; on the other hand, it reduces the vibration frequency of the baffle plate 3, which not only prevents interference between the baffle plate 3 and the equipment body 1, but also reduces noise.

[0114] Reference Figure 13-15 In some embodiments, a stopper 452 is formed within the track 451. When the shielding plate 3 moves from the first position to the second position, or from the second position to the first position, the stopper 452 can block the sliding portion 464, preventing the shielding plate 3 from continuing to move forward due to inertia, thereby preventing the shielding plate 3 from interfering with the device body 1 or other components of the cleaning device 100. The stopper 452 can have a certain degree of elasticity, so that the stopper 452 can buffer and protect the shielding plate 3, thereby reducing the friction between the shielding plate 3 and the stopper 452, and at the same time reducing the vibration generated when the sliding portion 464 contacts the stopper 452.

[0115] Reference Figure 13-15 In some embodiments, the track 451 includes a first section 4511, a second section 4512, a third section 4513, and a fourth section 4514, which are connected end to end. The first section 4511 and the third section 4513 are linear. The first section 4511 and the third section 4513 are disposed opposite each other on either side of the transmission wheel assembly 43c, extending in the front-to-back direction and vertically opposed to each other. The first section 4511 is located on the side of the first transmission wheel 437 and the second transmission wheel 438 that is closer to the top 16, while the third section 4513 is located on the side of the first transmission wheel 437 and the second transmission wheel 438 that is closer to the bottom 17. The second section 4512 and the fourth section 4514 are disposed opposite each other in the front-to-back direction, with the second section 4512 located on the side of the first transmission wheel 437 that is away from the second transmission wheel 438, and the fourth section 4514 located on the side of the second transmission wheel 438 that is away from the first transmission wheel 437. The second section 4512 and the fourth section 4514 are connected between the first section 4511 and the third section 4513 . The second section 4512 and the fourth section 4514 are both arranged in an arc shape, and the second section 4512 and the fourth section 4514 are bent in directions away from each other.

[0116] The track 451 formed by connecting the first section 4511 , the second section 4512 , the third section 4513 and the fourth section 4514 end to end is a closed-loop track 451 , so that the sliding portion 464 is not likely to fall off the track 451 during the sliding process along the track 451 .

[0117] The connection between the first section 4511 and the second section 4512, the connection between the second section 4512 and the third section 4513, the connection between the third section 4513 and the fourth section 4514, and the connection between the first section 4511 and the fourth section 4514 all have smooth transitions, thereby reducing the friction between the connection between the first section 4511 and the second section 4512 and the sliding part 464, the friction between the connection between the second section 4512 and the third section 4513 and the sliding part 464, the friction between the connection between the third section 4513 and the fourth section 4514 and the sliding part 464, and the friction between the connection between the first section 4511 and the fourth section 4514 and the sliding part 464.

[0118] In some embodiments, track 451 has a first node 4515, a second node 4516, and a third node 4517. Second node 4516 is located between first node 4515 and third node 4517.

[0119] When the shielding panel 3 moves from the first position to the second position, the sliding portion 464 moves from the first node 4515 to the third node 4517. When the shielding panel 3 moves from the second position to the first position, the sliding portion 464 moves from the third node 4517 to the first node 4515. The stopper 452 can be provided at the first node 4515 and the third node 4517. Alternatively, the stopper 452 can be provided on the side of the first node 4515 that deviates from the second node 4516, or on the side of the third node 4517 that deviates from the second node 4516. As long as the stopper 452 can prevent the sliding portion 464 from further movement when the shielding panel 3 moves from the first position to the second position and when the shielding panel 3 moves from the second position to the first position, it is sufficient.

[0120] Reference Figure 13-15In some embodiments, the first node 4515 may be located at the junction of the first segment 4511 and the second segment 4512, the second node 4516 may be located at the junction of the second segment 4512 and the third segment 4513, and the third node 4517 may be located at the junction of the third segment 4513 and the fourth segment 4514. In other embodiments, the first node 4515 may be located at the junction of the first segment 4511 and the fourth segment 4514, the second node 4516 may be located at the junction of the third segment 4513 and the fourth segment 4514, and the third node 4517 may be located at the junction of the second segment 4512 and the third segment 4513. In other embodiments, the first node 4515 may be located at the first segment 4511, the second node 4516 may be located at the second segment 4512, and the third node 4517 may be located at the third segment 4513. The positions of the first node 4515, the second node 4516 and the third node 4517 are not limited to the above-mentioned ones. It is only necessary to ensure that when the baffle plate 3 moves from the first position to the second position, the sliding part 464 can move from the first node 4515 to the third node 4517, and when the baffle plate 3 moves from the second position to the first position, the sliding part 464 moves from the third node 4517 to the first node 4515.

[0121] Reference Figure 13-15 In some embodiments, taking the case where the first node 4515 is located at the junction of the first section 4511 and the second section 4512, the second node 4516 is located at the junction of the second section 4512 and the third section 4513, the third node 4517 is located at the junction of the third section 4513 and the fourth section 4514, and the first side 31 of the baffle 3 faces the rear portion 15 of the device body 1 as an example, the working principles of the baffle 3 and the driving assembly 4 are introduced. The process of the driving mechanism 41 driving the connecting rod 46 to move to drive the baffle 3 to switch between the first position and the second position can be as follows: in the process of the baffle 3 moving from the first position to the second position, the driving mechanism 41 drives the transmission wheel assembly 43c to move, the transmission wheel assembly 43c cooperates with the conveyor belt 431 to drive the conveyor belt 431 to move, and the conveyor belt 431 moves to drive the connecting rod 46 to slide along the track 451. In the process of the sliding part 464 moving from the first node 4515 to the second node 4516, the first end 461 of the connecting rod 46 can rotate to drive the baffle 3 to lift, move toward the rear 15 of the device body 1 and move toward the bottom 17 of the device body 1. In the process of the sliding part 464 moving from the second node 4516 to the third node 4517, the connecting rod 46 drives the baffle 3 to move to the second position to cover the wiping surface 21.

[0122] During the process of the baffle plate 3 moving from the second position to the first position, the driving mechanism 41 drives the transmission wheel assembly 43c to move, and the transmission wheel assembly 43c cooperates with the conveyor belt 431 to drive the conveyor belt 431 to move. The conveyor belt 431 moves to drive the connecting rod 46 to slide along the track 451. During the process of the sliding part 464 moving from the third node 4517 to the second node 4516, the connecting rod 46 drives the baffle plate 3 to move toward the rear 15 of the device body 1. During the process of the sliding part 464 moving from the second node 4516 to the first node 4515, the first end 461 of the connecting rod 46 can rotate to drive the baffle plate 3 to lift and return to the first position.

The extension direction of the first rod segment 465 is parallel to the extension direction of the third rod segment 467, and there is an angle between the extension direction of the first rod segment 465 and the extension direction of the second rod segment 466, and between the extension direction of the second rod segment 466 and the extension direction of the third rod segment 467. There is a smooth transition between the first rod segment 465 and the second rod segment 466, and between the second rod segment 466 and the third rod segment 467, which is beneficial to improving the structural strength of the connecting rod 46 on the one hand, and making the connecting rod 46 more three-dimensional visually and increasing the design aesthetics on the other hand.

The conveyor belt 431 is accommodated in the guide groove 444 and can move along the extension direction of the guide groove 444. The third transmission wheel 439 cooperates with the conveyor belt 431 to drive the conveyor belt 431 to move. The conveyor belt 431 is accommodated in the guide groove 444 and can move along the extension direction of the annular groove guide groove 444, that is, the conveyor belt 431 can extend into the guide groove 444. When the driving mechanism 41 drives the third transmission wheel 439 to rotate, the third transmission wheel 439 cooperates with the conveyor belt 431 to drive the conveyor belt 431 to move. By connecting the second end 462 of the connecting rod 46 to the conveyor belt 431, the baffle 3 can be switched between the first position and the second position under the drive of the conveyor belt 431, thereby realizing the movement of the baffle 3 by transmission through the conveyor belt 431.

[0125] An annular guide groove 444 is formed on the mounting plate 441, and the conveyor belt 431 is accommodated in the guide groove 444 and can move along the extension direction of the guide groove 444, so that when the conveyor belt 431 drives the baffle plate 3 to move, the baffle plate 3 can rotate smoothly, thereby reducing the power required by the driving mechanism 41, which can achieve the purpose of reducing the energy consumption of the driving mechanism 41, making the driving mechanism 41 not easily damaged, and ensuring the service life of the driving mechanism 41; and reducing the vibration frequency of the baffle plate 3, which can not only prevent the baffle plate 3 from interfering with the equipment body 1, but also reduce noise.

[0126] Reference Figure 7 、 Figure 9 and Figure 10 According to some embodiments of the present invention, a mating groove 440 is formed on the outer peripheral wall of the third transmission wheel 439 and is arranged at intervals along the circumference of the third transmission wheel 439. The conveyor belt 431 includes a belt body 432 and a plurality of mating protrusions 433. The plurality of mating protrusions 433 are provided on the belt body 432 and are arranged at intervals along the circumference of the belt body 432.

The mating protrusion 433 is suitable for mating with the mating groove 440 to drive the conveyor belt 431 to move. The mating grooves 440 arranged at intervals along the circumference of the third transmission wheel 439 can engage with multiple mating protrusions 433 arranged at intervals along the circumference of the belt body 432. When the driving mechanism 41 drives the third transmission wheel 439 to rotate, the mating grooves 440 on the third transmission wheel 439 interact with the mating protrusions 433 on the belt body 432, so that the conveyor belt 431 moves with the rotation of the third rotating wheel, thereby realizing the process of the driving mechanism 41 driving the conveyor belt 431 to move through the third transmission wheel 439.

[0127] In the description of the embodiments of the present invention, “a plurality of” means two or more.

[0128] Reference Figure 7 According to some embodiments of the present invention, the groove wall surface of the mating groove 440 is an arc-shaped surface, which has a guiding effect on the mating process between the mating protrusion 433 and the mating groove 440, so that the mating protrusion 433 can enter the mating groove 440 or move out of the mating groove 440 more smoothly, so that the conveyor belt 431 can move more smoothly, and can also reduce the friction and wear caused by collision between the end faces of the mating protrusion 433 and the mating groove 440.

[0129] Reference Figure 9 and Figure 10According to some embodiments of the present invention, the surface of the mating protrusion 433 that faces the first side wall 445 is a first surface 434, and the first surface 434 is formed into an arcuate surface. The arcuate first surface 434 can reduce the contact area between the mating protrusion 433 and the first side wall 445, thereby reducing the frictional resistance between the mating protrusion 433 and the first side wall 445 during movement, allowing the conveyor belt 431 to move more smoothly.

[0130] Reference Figure 7 、 Figure 9 and Figure 10 According to some embodiments of the present invention, the groove wall surface of the mating groove 440 is an arcuate surface; and the surface of the mating protrusion 433 facing the first side wall 445 is a first surface 434, and the first surface 434 is formed into an arcuate surface. The groove wall surface of the mating groove 440 is an arcuate surface, which guides the mating protrusion 433 during the mating process with the mating groove 440, allowing the mating protrusion 433 to enter or move out of the mating groove 440 more smoothly. In addition, the first surface 434 is formed into an arcuate surface, which can reduce the contact area between the mating protrusion 433 and the first side wall 445, thereby reducing the frictional resistance between the mating protrusion 433 and the first side wall 445 during movement, allowing the conveyor belt 431 to move more smoothly.

[0131] Reference Figure 9 and Figure 10 According to some embodiments of the present invention, the conveyor belt 431 further includes a plurality of support protrusions 435. The plurality of support protrusions 435 are provided on the belt body 432 and are arranged at intervals along the circumference of the belt body 432. The support protrusions 435 are located on a side of the belt body 432 close to the second sidewall 446. The support protrusions 435 support the belt body 432. The plurality of support protrusions 435 are arranged at intervals along the circumference of the belt body 432. On the one hand, the plurality of support protrusions 435 can evenly share the weight of the belt body 432, reducing or preventing the possibility of deformation of the belt body 432. On the other hand, the plurality of support protrusions 435 support the belt body 432 and are located on a side of the belt body 432 close to the second sidewall 446, so that the conveyor belt 431 does not sway or shake during movement, thereby improving the stability of the conveyor belt 431.

[0132] Reference Figure 7 、 Figure 9 and Figure 10According to some embodiments of the present invention, the surface of the support protrusion 435 facing the second side wall 446 is the second surface 436, and the second surface 436 is formed into an arcuate surface. By forming the second surface 436 into an arcuate surface, the contact area between the support protrusion 435 and the second side wall 446 can be reduced, thereby reducing the frictional resistance between the support protrusion 435 and the second side wall 446 during movement, allowing the conveyor belt 431 to move more smoothly.

[0133] Optionally, the number of supporting protrusions 435 and the matching protrusions 433 are the same and they correspond one-to-one. Each supporting protrusion 435 and the corresponding matching protrusion 433 are arranged opposite to each other along the thickness direction of the belt body 432. Multiple matching protrusions 433 are located on the side of the belt body 432 close to the first side wall 445, and multiple supporting protrusions 435 are located on the side of the belt body 432 close to the second side wall 446, and the number of supporting protrusions 435 and the matching protrusions 433 are the same and they correspond one-to-one. On the one hand, the matching protrusions 433 and the supporting protrusions 435 can share the weight of the belt body 432 more evenly, reducing or avoiding the possibility of deformation of the belt body 432. On the other hand, the matching protrusions 433 and the supporting protrusions 435 jointly support the belt body 432, so that the conveyor belt 431 will not swing or shake during movement, which can further enhance the stability of the conveyor belt 431.

[0134] Reference Figure 6-Figure 8 According to some embodiments of the present invention, a receiving groove 447 is formed on the mounting plate 441. The third transmission wheel 439 is located within the receiving groove 447. The receiving groove 447 and the guide groove 444 are located on the same side of the mounting plate 441, and the receiving groove 447 extends through the sidewall of the guide groove 444. The receiving groove 447 facilitates the reception of the third transmission wheel 439 therein, thereby facilitating the engagement of the mating groove 440 on the third transmission wheel 439 with the mating protrusion 433 of the conveyor belt 431 to drive the conveyor belt 431. This also allows the overall structure of the third transmission wheel 439 and the mounting plate 441 to be compact.

[0135] For example, the driving mechanism 41 is arranged inside the device body 1 to reduce the occupation of the external space of the device body 1. The side wall of the guide groove 444 is penetrated by the accommodating groove 447, and the third transmission wheel 439 is located in the accommodating groove 447, which can facilitate the connection between the driving mechanism 41 and the third transmission wheel 439 to drive the third transmission wheel 439 to move.

[0136] Reference Figure 6-Figure 8According to some embodiments of the present invention, the accommodating groove 447 is located in the space surrounded by the guide groove 444. Since the third transmission wheel 439 is located in the accommodating groove 447, and the accommodating groove 447 is located in the space surrounded by the guide groove 444, the matching groove 440 on the third transmission wheel 439 can be effectively matched with the matching protrusion 433 on the conveyor belt 431, thereby realizing the driving of the conveyor belt 431 by the third transmission wheel 439.

[0137] Reference Figure 2 、 Figure 6 and Figure 8 According to some embodiments of the present invention, the mounting plate 441 includes a first mounting plate 442 and a second mounting plate 443 that can be movably connected. Part of the guide groove 444 is formed on the first mounting plate 442, and another part of the guide groove 444 is formed on the second mounting plate 443. The first mounting plate 442 is fixed to the device body 1, and the second mounting plate 443 can swing between a storage position and an expanded position relative to the first mounting plate 442. In the storage position, the second mounting plate 443 is attached to the outer surface of the device body 1 and the second mounting plate 443 is arranged at an angle to the first mounting plate 442. In the expanded position, the second mounting plate 443 is spaced apart from the device body 1 and the second mounting plate 443 and the first mounting plate 442 are arranged in a straight line.

[0138] Among them, the first position is the position where the shielding plate 3 exposes the wiping surface 21, and the second position is the position where the shielding plate 3 blocks the wiping surface 21. During the process of switching the shielding plate 3 between the first position and the second position, the second mounting plate 443 is in the expanded position, and when the shielding plate 3 is in the first position or the second position, the second mounting plate 443 is in the stored position.

[0139] When the shielding plate 3 is in the first position or the second position, the second mounting plate 443 is in the storage position. By having the second mounting plate 443 affixed to the outer surface of the device body 1 and the second mounting plate 443 and the first mounting plate 442 being arranged at an angle, the overall structure of the shielding plate 3, the drive assembly 4, and the device body 1 can be made compact, reducing the space occupied by the cleaning device 100 as a whole and facilitating the storage and transportation of the cleaning device 100. When the shielding plate 3 switches between the first position and the second position, the second mounting plate 443 is in the deployed position and the second mounting plate 443 and the first mounting plate 442 are arranged in a straight line, which can cause the guide groove 444 on the mounting plate 441 to be arranged in a straight line, thereby causing the transmission belt in the guide groove 444 to be arranged in a straight line, ensuring the stable operation of the transmission belt 431, and thus realizing the process of the drive assembly 4 driving the shielding plate 3 to switch between the first position and the second position.

[0140] For example, a receiving groove 447 is formed on the first mounting plate 442, and the third transmission wheel 439 is located in the receiving groove 447. The receiving groove 447 and the guide groove 444 are located on the same side of the mounting plate 441. The receiving groove 447 passes through the side wall of the guide groove 444. The receiving groove 447 can facilitate the third transmission wheel 439 to be accommodated therein, and then facilitate the matching groove 440 on the third transmission wheel 439 to match with the matching protrusion 433 of the conveyor belt 431 to drive the conveyor belt 431 to move, and can make the overall structure of the third transmission wheel 439 and the mounting plate 441 compact.

[0141] The second mounting plate 443 has a storage position and an expanded position. When the baffle plate 3 is in the first position or the second position, the second mounting plate 443 is in the storage position. At this time, the second mounting plate 443 is attached to the outer surface of the equipment body 1 and the second mounting plate 443 is set at an angle to the first mounting plate 442, which can further make the overall structure of the baffle plate 3, the driving assembly 4 and the equipment body 1 compact, reduce the space occupied by the cleaning equipment 100 as a whole, and facilitate the storage and transportation of the cleaning equipment 100.

[0142] When the baffle plate 3 switches between the first position and the second position, the second mounting plate 443 is in the expanded position and the second mounting plate 443 and the first mounting plate 442 are arranged in a straight line, so that the guide groove 444 on the mounting plate 441 can be arranged in a straight line, and then the transmission belt in the guide groove 444 can be arranged in a straight line, ensuring the stable operation of the conveyor belt 431, and then realizing the process of the driving component 4 driving the baffle plate 3 to switch between the first position and the second position.

[0143] Reference Figure 5 、 Figure 6 and Figure 8 According to some embodiments of the present invention, the drive assembly 4 further includes an elastic return member 47, one end of which is connected to the second mounting plate 443 and the other end of which is connected to the first mounting plate 442. The elastic return member 47 is used to drive the second mounting plate 443 to the storage position. By providing the elastic return member 47, the elastic return member 47 provides a driving force to drive the mounting plate 441 from the deployed position to the storage position, so that the elastic return member 47 and the conveyor belt 431 cooperate to control the movement of the second mounting plate 443 between the storage position and the deployed position. When the shielding plate 3 is in the first position or the second position, the second mounting plate 443 is in the storage position, thereby reducing the space occupied by the cleaning device 100 as a whole.

[0144] For example, when the baffle plate 3 switches between the first position and the second position, the driving mechanism 41 can drive the conveyor belt 431 to move via the third transmission wheel 439, and the driving force transmitted to the conveyor belt 431 by the driving mechanism 41 can overcome the elastic force of the elastic return member 47 to make the second mounting plate 443 in the expanded position, so that the second mounting plate 443 and the first mounting plate 442 are arranged in a straight line, ensuring the stability of the conveyor belt 431 during movement, thereby realizing the process of the driving mechanism 41 driving the baffle plate 3 to switch between the first position and the second position via the conveyor belt 431; when the baffle plate 3 is in the first position or the second position, the driving mechanism 41 stops transmitting power to the conveyor belt 431, and under the action of the elastic restoring force of the elastic return member 47, the second mounting plate 443 can automatically return from the expanded position to the stored position.

[0145] Reference Figure 7 、 Figure 9 and Figure 10 According to some embodiments of the present invention, the conveyor belt 431 includes at least three conveyor belt segments 448 connected end to end. Adjacent conveyor belt segments 448 are rotatably connected to form at least three rotation connection points 449. In the stowed position, two rotation connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. The conveyor belt 431 includes at least three conveyor belt segments 448. Adjacent conveyor belt segments 448 are rotatably connected to form at least three rotation connection points 449. When in the storage position, two of the rotating connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. The two rotating connection points 449 can be used to realize that the conveyor belt segment 448 accommodated in the first mounting plate 442 and the conveyor belt segment 448 accommodated in the second mounting plate 443 are set at an angle, so that the conveyor belt segment 448 accommodated in the second mounting plate 443 can also fit into the outer surface of the equipment body 1, reducing the space occupied by the cleaning equipment 100 as a whole, making the overall structure of the cleaning equipment 100 compact, and facilitating the transportation and storage of the cleaning equipment 100.

[0146] Reference Figure 7 、 Figure 9 and Figure 10According to some embodiments of the present invention, the conveyor belt 431 includes four conveyor belt segments 448, with four rotation connection points 449 formed on the conveyor belt 431. When the shielding plate 3 is in the first position, two of the rotation connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. When the shielding plate 3 is in the second position, the other two rotation connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. The conveyor belt 431 is composed of four conveyor belt segments 448, and the four conveyor belt segments 448 are rotatably connected to form four rotation connection points 449. When the shielding plate 3 is in different positions, the conveyor belt 431 can change the angular position between adjacent conveyor belt segments 448 of the conveyor belt 431 as the position of the shielding plate 3 changes.

[0147] For example, when the baffle plate 3 is in the first position, two of the rotating connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442, so that the conveyor belt segment 448 accommodated in the second mounting plate 443 is arranged at an angle to the conveyor belt segment 448 accommodated in the first mounting plate 442, so that the conveyor belt segment 448 accommodated in the second mounting plate 443 is also attached to the outer surface of the equipment body 1. At this time, the second mounting plate 443 is in the storage position and the second mounting plate 443 is attached to the outer surface of the equipment body 1, which can reduce the space occupied by the cleaning equipment 100 as a whole, making the overall structure of the cleaning equipment 100 compact.

[0148] During the process of switching the baffle plate 3 from the first position to the second position, the two rotating connection points 449 are rotated to make the second mounting plate 443 in the expanded position and the second mounting plate 443 and the first mounting plate 442 arranged in a straight line, so that the guide groove 444 on the mounting plate 441 can be arranged in a straight line to ensure the stable operation of the conveyor belt 431, thereby realizing the process of the driving component 4 driving the baffle plate 3 to switch between the first position and the second position.

[0149] For another example, when the baffle plate 3 is in the second position, the other two rotating connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442, so that the conveyor belt segment 448 accommodated in the second mounting plate 443 is set at an angle to the conveyor belt segment 448 accommodated in the first mounting plate 442, so that the conveyor belt segment 448 accommodated in the second mounting plate 443 is also attached to the outer surface of the equipment body 1. At this time, the second mounting plate 443 is in the storage position and the second mounting plate 443 is attached to the outer surface of the equipment body 1, which can reduce the space occupied by the cleaning equipment 100 as a whole, making the overall structure of the cleaning equipment 100 compact.

[0150] During the process of switching the baffle plate 3 from the second position to the first position, the other two rotating connection points 449 are rotated and connected so that the second mounting plate 443 is in the expanded position and the second mounting plate 443 and the first mounting plate 442 are arranged in a straight line, so that the guide groove 444 on the mounting plate 441 can be arranged in a straight line, and then the transmission belt in the guide groove 444 can be arranged in a straight line, ensuring the stable operation of the conveyor belt 431, and then realizing the process of the driving component 4 driving the baffle plate 3 to switch between the first position and the second position.

[0151] The conveyor belt 431 includes four conveyor belt segments 448, and four rotating connection points 449 are formed on the conveyor belt 431. When the baffle plate 3 is in the first position, two of the rotating connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. When the baffle plate 3 is in the second position, the other two rotating connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. By adjusting the rotating connection points 449 to adjust the angle between two adjacent conveyor belt segments 448, the overall shape of the conveyor belt 431 can be changed, and then the conveyor belt 431 can be dynamically adjusted as the position of the baffle plate 3 changes. When the baffle plate 3 is in the first position or the second position, the overall structure of the cleaning equipment 100 can be made compact, which is convenient for transportation or storage.

On the other hand, the baffle plate 3 is supported by the two connecting rods 46, the first connecting rod 46a and the second connecting rod 46b, so that the baffle plate 3 will not swing or shake during the movement, thereby improving the stability of the baffle plate 3.

[0159] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the wiping assembly 2 can move vertically relative to the device body 1. By making the wiping assembly 2 movable vertically relative to the device body 1, when the wiping assembly 2 does not need to contact the second working surface, it can move upward relative to the device body 1 to prevent the wiping assembly 2 from causing unnecessary contamination to the second working surface; and when the shielding plate 3 needs to be switched to the second position to shield the wiping surface 21, the wiping assembly 2 can move upward relative to the device body 1 to avoid the shielding plate 3.

[0160] Reference Figure 13-15 According to some embodiments of the present invention, the device body 1 is formed with a accommodating cavity 19, and an opening 191 of the accommodating cavity 19 is opened at the bottom 17. The cleaning device 100 also includes a lifting assembly 6, and the lifting assembly 6 and the wiping assembly 2 are both accommodated in the accommodating cavity 19, or the lifting assembly 6 is arranged in the accommodating cavity 19, at least part of the lifting assembly 6 passes through the opening 191 and the lifting assembly 6 is connected to the wiping assembly 2, and the lifting assembly 6 is used to drive the wiping assembly 2 to rise and fall.

[0161] By accommodating the lifting assembly 6 and the wiping assembly 2 in the accommodating chamber 19, or arranging the lifting assembly 6 in the accommodating chamber 19, at least part of the lifting assembly 6 passes through the opening 191 and the lifting assembly 6 is connected to the wiping assembly 2, the lifting assembly 6 is used to drive the wiping assembly 2 to be accommodated in the accommodating chamber 19 or close to the opening 191 of the accommodating chamber 19 when the cleaning equipment 100 is about to run to the second working surface, that is, to drive the wiping assembly 2 to rise to leave the second working surface. The lifting assembly 6 is also used to drive the wiping assembly 2 away from the opening 191 and the accommodating chamber 19 after the cleaning equipment 100 runs from the second working surface to the first working surface, that is, to drive the wiping assembly 2 to descend, so as to wipe the working surface to be wiped.

[0162] The fact that at least part of the lifting assembly 6 passes through the opening 191 may include the following situations: for example, a part of the lifting assembly 6 passes through the opening 191 ; for another example, all of the lifting assembly 6 passes through the opening 191 .

[0163] For example, the lifting assembly 6 can use a pull rope, a gear rack, a cam, etc. to control the lifting of the wiping assembly 2.

[0164] Reference Figure 13-15 According to some embodiments of the present invention, a first groove 11 is formed on the bottom 17 of the device body 1. The first groove 11 is connected to the accommodating chamber 19 through an opening 191. The first groove 11 is used to accommodate the wiping assembly 2 or to accommodate the wiping assembly 2 and at least a portion of the shielding plate 3. The first groove 11, the opening 191, and the accommodating chamber 19 are connected in sequence. The first groove 11 is used to accommodate the wiping assembly 2 or to accommodate the wiping assembly 2 and at least a portion of the shielding plate 3. When the cleaning device 100 is about to move to the second working surface and the lifting assembly 6 drives the wiping assembly 2 to rise, the wiping assembly 2 can be accommodated in the first groove 11. When the wiping assembly 2 is accommodated in the first groove 11, the side of the wiping assembly 2 facing the opening 191 can be aligned with the opening 191. At this time, the first groove 11 has an empty accommodating space on the side of the wiping assembly 2 facing away from the opening 191 for accommodating at least a portion of the shielding plate 3. Alternatively, the wiping assembly 2 can fill the entire first groove 11 after being accommodated in the first groove 11.

[0165] The first groove 11 may be used to accommodate at least part of the shielding plate 3 , which may include the following situations: for example, the first groove 11 may be used to accommodate a part of the shielding plate 3 ; for another example, the first groove 11 may be used to accommodate all of the shielding plate 3 .

[0166] Reference Figure 2 and Figure 3According to some embodiments of the present invention, the wiping assembly 2 is movable in a vertical direction between an extended position and a retracted position. The retracted position is higher than the extended position. When the shielding plate 3 is in the second position, the wiping assembly 2 is in the retracted position. By ensuring that the wiping assembly 2 is in the retracted position when the shielding plate 3 is in the second position, the distance between the wiping assembly 2 in the retracted position and the work surface is greater, thereby avoiding the shielding plate 3 and facilitating a smooth transition of the shielding plate 3 to the second position.

[0167] Optionally, when the wiping assembly 2 is in the extended position, the wiping assembly 2 contacts the first working surface to wipe the first working surface. When the shielding plate 3 is in the first position, the wiping assembly 2 can be in the extended position, the wiping assembly 2 contacts the first working surface to wipe the first working surface; the wiping assembly 2 can also be in the retracted position, the wiping assembly 2 is spaced apart from the working surface.

[0168] For example, after the cleaning device 100 runs from the second working surface to the first working surface, the shielding plate 3 is in the first position, and the wiping component 2 is in the extended position and contacts the working surface to wipe the first working surface; when the cleaning device 100 is about to run to the second working surface, the wiping component 2 moves upward from the extended position to the retracted position relative to the device body 1, and the shielding plate 3 switches from the first position to the second position.

[0169] For another example, when the cleaning device 100 cleans the first working surface, the shielding plate 3 is in the first position, and the wiping assembly 2 is in the extended position and contacts the first working surface to wipe the first working surface. When the wiping assembly 2 becomes contaminated, the wiping assembly 2 can move upward from the extended position to the retracted position relative to the device body 1 to be separated from the first working surface.

[0170] For another example, when the cleaning device 100 cleans the first working surface, the wiping assembly 2 is in the extended position and contacts the first working surface to wipe the first working surface. When the wiping assembly 2 becomes contaminated, the wiping assembly 2 can move upward from the extended position to the retracted position relative to the device body 1 to be separated from the first working surface, and the shielding plate 3 can also be switched from the first position to the second position to block the wiping surface 21 of the wiping assembly 2.

The receiving groove 447 and the guide groove 444 are located on the same side of the mounting plate 441 and extend through the side walls of the guide groove 444. The mounting plate 441 includes a first mounting plate 442 and a second mounting plate 443 that can be movably connected. A portion of the guide groove 444 is formed on the first mounting plate 442, and another portion of the guide groove 444 is formed on the second mounting plate 443. The first mounting plate 442 is fixed to the device body 1, and the second mounting plate 443 can swing between a storage position and an expanded position relative to the first mounting plate 442. In the storage position, the second mounting plate 443 is attached to the outer surface of the device body 1 and the second mounting plate 443 is set at an angle to the first mounting plate 442. In the expanded position, the second mounting plate 443 is fixed to the outer surface of the device body 1 and the second mounting plate 443 is set at an angle to the first mounting plate 442. The mounting plate 443 is spaced apart from the device body 1 and the second mounting plate 443 and the first mounting plate 442 are arranged in a straight line, wherein the driving component 4 is used to drive the shielding plate 3 to switch between the first position and the second position, the first position is the position where the shielding plate 3 exposes the wiping surface 21, and the second position is the position where the shielding plate 3 blocks the wiping surface 21. During the switching of the shielding plate 3 between the first position and the second position, the second mounting plate 443 is in the expanded position, and when the shielding plate 3 is in the first position or the second position, the second mounting plate 443 is in the stored position.

[0180] One end of the elastic return member 47 is connected to the second mounting plate 443 and the other end of the elastic return member 47 is connected to the first mounting plate 442. The elastic return member 47 is used to drive the second mounting plate 443 to move to the storage position.

[0181] The connecting rod 46 has a first end 461 and a second end 462 . The first end 461 is connected to the shielding plate 3 , and the second end 462 is detachably connected to the conveyor belt 431 .

[0182] The transmission wheel assembly 43c includes a third transmission wheel 439, which is located in the accommodating groove 447. The driving mechanism 41 is connected to the third transmission wheel 439 to drive the third transmission wheel 439 to rotate. The outer peripheral wall of the third transmission wheel 439 is formed with matching grooves 440 arranged at intervals along the circumference of the third transmission wheel 439, and the groove wall surface of the matching groove 440 is an arc surface.

[0183] The conveyor belt 431 includes a belt body 432, a plurality of mating protrusions 433 and a plurality of supporting protrusions 435. The plurality of mating protrusions 433 are provided on the belt body 432 and are arranged at intervals along the circumference of the belt body 432. The plurality of mating protrusions 433 are provided on the belt body 432 and are arranged at intervals along the circumference of the belt body 432. The mating protrusions 433 are located on the side of the belt body 432 close to the first side wall 445. The surface of the mating protrusion 433 facing the first side wall 445 is the first surface 434. The first surface 434 is formed as an arc-shaped surface. The mating protrusion 433 is suitable for mating with the mating groove 440 to drive the conveyor belt 431 to move. Multiple support protrusions 435 are provided on the belt body 432 and are arranged at intervals along the circumference of the belt body 432. The support protrusions 435 are located on the side of the belt body 432 close to the second side wall 446. The surface of the support protrusion 435 facing the second side wall 446 is the second surface 436, and the second surface 436 is formed as an arc surface.

[0184] The conveyor belt 431 includes four transmission belt segments connected end to end in sequence. Two adjacent conveyor belt segments 448 can be rotatably connected to form four rotation connection points 449. When the baffle plate 3 is in the first position, two of the rotation connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442. When the baffle plate 3 is in the second position, the other two rotation connection points 449 are located at the connection between the second mounting plate 443 and the first mounting plate 442.

[0185] The device body 1 has a first side portion 12 and a second side portion 13 that are oppositely arranged along the left-right direction. The left-right direction intersects with the vertical direction. There are two groups of transmission components 43 and two connecting rods 46. The two groups of transmission components 43 are respectively arranged on the first side portion 12 and the second side portion 13. The two connecting rods 46 are located on opposite sides of the device body 1 along the left-right direction and correspond to the two groups of transmission components 43 respectively.

[0186] For example, when the wiping component 2 is wiping the first working surface, the cleaning device 100 is about to run to the second working surface, and the process of the baffle 3 moving from the first position to the second position can be: the driving mechanism 41 drives the third transmission wheel 439 to rotate, and through the cooperation between the matching groove 440 on the third transmission wheel 439 and the matching protrusion 433 on the conveyor belt 431, the rotation of the third transmission wheel 439 can drive the conveyor belt 431 to move, and the conveyor belt 431 moves to drive the connecting rod 46 to slide. During the sliding process of the connecting rod 46, the first end 461 of the connecting rod 46 can rotate to drive the baffle 3 to lift, move toward the rear 15 of the equipment body 1 and move toward the bottom 17 of the equipment body 1, and the connecting rod 46 can drive the baffle 3 to move to the second position.

[0187] In addition, the lifting assembly 6 drives the wiping assembly 2 to move upward from the extended position to the retracted position relative to the equipment body 1. The distance between the wiping assembly 2 in the retracted position and the second working surface is larger, which can avoid the shielding plate 3 so that the shielding plate 3 can smoothly switch to the second position to cover the wiping surface 21.

[0188] For another example, when the cleaning equipment 100 runs from the second working surface to the first working surface, during the process of the baffle 3 moving from the second position to the first position, the driving mechanism 41 drives the transmission wheel assembly 43c to move, and the transmission wheel assembly 43c cooperates with the conveyor belt 431 to drive the conveyor belt 431 to move, and the conveyor belt 431 moves to drive the connecting rod 46 to slide. During the sliding of the connecting rod 46, the connecting rod 46 drives the baffle 3 to move toward the rear 15 of the equipment body 1, and the first end 461 of the connecting rod 46 can be rotated to drive the baffle 3 to lift and return to the first position. The lifting assembly 6 can drive the wiping assembly 2 to move downward from the retracted position to the extended position relative to the equipment body 1, so that the wiping assembly 2 contacts the first working surface to wipe the first working surface.

[0189] Next, we will refer to Figure 11-Figure 15 The cleaning device 100 of another embodiment of the present invention is described. In this embodiment, the same parts as the above embodiment are not described again, and the above embodiment can be referred to, and the main difference from the above embodiment is described.

[0190] The transmission assembly 43 includes a transmission wheel assembly 43c, a transmission belt, and a mounting plate 441. The transmission wheel assembly 43c includes a first transmission wheel 437 and a second transmission wheel 438. The first transmission wheel 437 and the second transmission wheel 438 are spaced apart in the front-to-back direction. The conveyor belt 431 is sleeved on the first transmission wheel 437 and the second transmission wheel 438. The drive mechanism 41 is connected to the first transmission wheel 437. In this case, the first transmission wheel 437 is the driving wheel and the second transmission wheel 438 is the driven wheel. The drive mechanism 41 is used to drive the first transmission wheel 437 to rotate, thereby driving the second transmission wheel 438 and the conveyor belt 431 to move.

[0191] The surface of the conveyor belt 431 facing the transmission wheel assembly 43c is formed with alternating convex teeth and tooth grooves, and the surfaces of the first transmission wheel 437 and the second transmission wheel 438 facing the conveyor belt 431 are both formed with alternating convex teeth and tooth grooves. The tooth grooves of the first transmission wheel 437 and the second transmission wheel 438 are engaged with the convex teeth of the conveyor belt 431. The transmission connection between the transmission wheel assembly 43c and the conveyor belt 431 is achieved by the engagement of the convex teeth and the tooth grooves, so that when the driving mechanism 41 drives the first transmission wheel 437 to rotate, the conveyor belt 431 can be driven to move.

[0192] The mounting plate 441 forms a track 451, and at least part of the track 451 is arranged around the conveyor belt 431. The second end 462 of the connecting rod 46 is provided with a first mounting portion 463 and a sliding portion 464. The first mounting portion 463 is connected to the conveyor belt 431, and the sliding portion 464 is slidably arranged on the track 451. The sliding portion 464 can extend into the track 451. When the driving mechanism 41 drives the conveyor belt 431 and the baffle 3 to move, the sliding portion 464 can slide along the track 451.

[0193] An angle is formed between the first mounting portion 463 and the sliding portion 464, so that the first mounting portion 463 can be set on the conveyor belt 431, and the sliding portion 464 can be slidably set in the track 451, and the first mounting portion 463 and the sliding portion 464 can move along their respective tracks under the drive of the conveyor belt 431 without interfering with each other.

[0194] A stopper 452 is formed in the track 451. When the shielding plate 3 moves from the first position to the second position, or from the second position to the first position, the stopper 452 can block the sliding portion 464 so that the shielding plate 3 will not continue to move forward under the action of inertia, thereby preventing the shielding plate 3 from interfering with the equipment body 1 or other components of the cleaning equipment 100.

[0195] Reference Figure 1 、 Figure 11 and Figure 12 According to the second aspect of the present invention, the cleaning system includes a cleaning device 100 and a cleaning base station. The cleaning device 100 is the cleaning device 100 of the first aspect of the present invention. The cleaning device 100 is suitable for cooperating with the cleaning base station. The cleaning base station is used to clean and / or charge the cleaning device 100.

[0196] According to the cleaning system of the embodiment of the present invention, the above-mentioned cleaning device 100 is provided, and the driving component 4 of the cleaning device 100 is arranged on the device body 1 and the driving component 4 is connected to the baffle 3, so that the driving component 4 can drive the baffle 3 to move to expose the wiping surface 21, so that the wiping surface 21 contacts the first working surface to wipe the first working surface; and the driving component 4 can also drive the baffle 3 to move to block the wiping surface 21, so as to effectively isolate the wiping surface 21 from the second working surface, thereby effectively avoiding the wiping surface 21 from causing contamination to the working surface. For example, when the cleaning device 100 runs to the second working surface, the baffle 3 blocks the wiping surface 21 to avoid the wiping surface 21 from contacting the second working surface, thereby effectively avoiding the second working surface from being contaminated or wetted by the wiping surface 21.

[0197] Reference Figure 1 、 Figure 11 and Figure 12According to the control method of the cleaning device 100 of the third aspect embodiment of the present utility model, the cleaning device 100 is the cleaning device 100 according to the above-mentioned first aspect embodiment of the present utility model. The control method of the cleaning device 100 includes: controlling the baffle 3 to block or expose the wiping surface 21 according to the area where the cleaning device 100 is located.

[0198] According to the control method of the cleaning device 100 of the embodiment of the present invention, by providing the above-mentioned cleaning device 100, by arranging the driving component 4 of the cleaning device 100 on the device body 1 and connecting the driving component 4 to the baffle 3, the driving component 4 can drive the baffle 3 to move to expose the wiping surface 21, so that the wiping surface 21 contacts the first working surface to wipe the first working surface; and the driving component 4 can also drive the baffle 3 to move to block the wiping surface 21, so as to effectively isolate the wiping surface 21 from the second working surface, thereby effectively avoiding the wiping surface 21 from causing contamination to the working surface. For example, when the cleaning device 100 runs to the second working surface, the baffle 3 blocks the wiping surface 21 to avoid the wiping surface 21 from contacting the second working surface, thereby effectively avoiding the second working surface from being contaminated or wetted by the wiping surface 21.

[0199] Reference Figure 1 、 Figure 1 and Figure 12 Referring to some embodiments of the present invention, controlling the shielding plate 3 to shield or expose the wiping surface 21 according to the area where the cleaning device 100 is located includes: controlling the shielding plate 3 to shield or expose the wiping surface 21 according to the condition of the surface to be worked on in the area where the cleaning device 100 is located. For example, whether to expose or shield 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 assembly 2, the shielding plate 3 is controlled 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 assembly 2, the shielding plate 3 is controlled to move to shield the wiping surface 21.

[0200] 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 shielding plate 3 is controlled to move to expose the wiping surface 21. If the degree of dirtiness of the surface to be worked on is small, the shielding plate 3 is controlled to move to block the wiping surface 21.

[0201] Reference Figure 1 、 Figure 1 and Figure 12With reference to some embodiments of the present invention, the condition of the surface to be worked on includes: the material of the surface to be worked on or the degree of dirtiness of the surface to be worked on. For example, the surface to be worked on is divided into a first work surface and a second work surface. The first work surface and the second work surface can be distinguished based on the material. The first work surface can be a hard surface such as a tile, floor, or cement floor, while the second work surface can be a soft surface such as a fiber surface (e.g., carpet). The first work surface and the second work surface can also be distinguished based on the degree of dirtiness of the surface to be worked on, with the first work surface being more severely dirtied than the second work surface.

[0202] 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 baffle 3 can be controlled to move to the side of the wiping component 2 facing the first working surface to block the wiping surface 21, so that when the cleaning device 100 runs to the second working surface, the baffle 3 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; when the cleaning device 100 runs from the second working surface to the first working surface, the baffle 3 is controlled to move to expose the wiping surface 21, so that the wiping surface 21 can contact the first working surface to wipe the first working surface.
