Description

Technical Field

[0001] This invention relates to the field of household appliances, and in particular to a cleaning device and a cleaning system. Background Technology

[0002] In related technologies, cleaning equipment drives the wiping component to rise and fall through a lifting mechanism. When the cleaning equipment moves to a specific area, the wiping component can be raised through the lifting mechanism to avoid the wiping component affecting the surface to be worked on in that specific area. However, the lifting height of the wiping component is not high enough, and the wiping component will still affect the surface to be worked on in that specific area when the cleaning equipment moves to that specific area. Summary of the Invention

[0003] Therefore, this invention provides a cleaning device. By connecting a wiping component to a lifting component, the wiping component is vertically and flexibly positioned at the bottom of the device body. A drive component is positioned on the device body, and a baffle is connected to the drive component. This allows the drive component to move the baffle to expose the wiping surface, facilitating wiping of the first working surface. The drive component can also move the baffle to block the wiping surface, effectively isolating it from the second working surface and preventing contamination of the second working surface by the wiping component. Furthermore, by moving the baffle between the first and second positions to create space for the wiping component to lift, the wiping component can perform its lifting action more smoothly.

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

[0090] The following is for reference. Figures 1-17 A cleaning device 100 according to an embodiment of the present invention is described.

[0091] Reference Figure 2 , Figure 4 and Figure 8 According to a first aspect of the present invention, a cleaning device 100 includes a device body 1, a wiping assembly 2, a lifting assembly, a baffle plate 4, and a drive assembly 5. The wiping assembly 2 is disposed at the bottom 11 of the device body 1 and has a wiping surface 21. The lifting assembly is mounted on the device body 1 and connected to the wiping assembly 2. The lifting assembly drives the wiping assembly 2 to move up and down between an extended position and a retracted position, with the retracted position being higher than the extended position. The baffle plate 4 has a first position and a second position. When the baffle plate 4 is in the first position and the wiping assembly 2 is in the extended position, the wiping surface 21 is exposed. When the baffle plate 4 is in the first position and the wiping assembly 2 is in the retracted position, the baffle plate 4 covers the wiping surface 21. When the baffle plate 4 is in the second position, the baffle plate 4 is used to allow space for the wiping assembly 2 to move. The drive assembly 5 is disposed on the device body 1 and connected to the baffle plate 4. The drive assembly 5 drives the baffle plate 4 to move between the first position and the second position.

[0092] The main body 1 can serve as the basic carrier of the cleaning equipment 100. The main body 1 can be an integral structure or a combination structure formed by the cooperation of multiple parts. The main body 1 plays a role in supporting and protecting other parts of the cleaning equipment 100. These other parts include the baffle 4, the lifting assembly, the wiping assembly 2, and the drive assembly 5, but are not limited to these.

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

[0094] The drive assembly 5 is connected to the baffle plate 4. The drive assembly 5 drives the baffle plate 4 to move, either to expose the wiping surface 21 or to cover the wiping surface 21. Furthermore, the drive assembly 5 drives the baffle plate 4 to move between a first position and a second position to allow space for the wiping assembly 2 to move, thus enabling the wiping assembly 2 to move more smoothly between the retracted and extended positions. The decision to expose or cover the wiping surface 21 can be determined based on the surface to be worked on.

[0095] For example, the material of the surface to be worked on can be used to determine whether to expose the wiping surface 21 or to cover the wiping surface 21. If the material of the surface to be worked on is suitable for the wiping component 2 to wipe, the driving component 5 drives the cover plate 4 to move to expose the wiping surface 21. If the material of the surface to be worked on is not suitable for the wiping component 2 to wipe, the driving component 5 drives the cover plate 4 to move to cover the wiping surface 21.

[0096] For example, the degree of dirt on the surface to be worked on can be used to determine whether to expose the wiping surface 21 or to cover it. If the surface to be worked on is heavily soiled, the drive assembly 5 drives the cover plate 4 to move to expose the wiping surface 21. If the surface to be worked on is lightly soiled, the drive assembly 5 drives the cover plate 4 to move to cover the wiping surface 21.

[0097] In addition, users can 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's settings.

[0098] For example, the surfaces to be worked on can be divided into a first working surface and a second working surface. The first and second working surfaces can be distinguished by material: the first working surface can be a hard surface such as tile, flooring, or cement, while the second working surface can be a soft surface such as a fibrous surface (e.g., carpet). The first and second working surfaces can also be distinguished by the degree of dirtiness, with the first working surface being dirtier than the second. Alternatively, the first and second working surfaces can be set by the user.

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

[0100] When the cleaning equipment 100 moves from the second working surface to the first working surface, the drive assembly 5 drives the baffle 4 to move from the first position to the second position to make way for the lifting space of the wiping assembly 2. After the lifting assembly drives the wiping assembly 2 to move down from the retracted position to the extended position, the drive assembly 5 drives the baffle 4 to move from the second position to the first position, so that the baffle 4 is located on the side of the wiping assembly 2 away from the first working surface, so as to expose the wiping surface 21 for wiping the first working surface.

[0101] By connecting the wiping assembly 2 to the lifting assembly, the wiping assembly 2 can be lifted and positioned at the bottom 11 of the main body 1. The drive assembly 5 is positioned on the main body 1 and the baffle plate 4 is connected to the drive assembly 5, so that the drive assembly 5 can drive the baffle plate 4 to move to expose the wiping surface 21, so that the wiping surface 21 can wipe the first working surface. The drive assembly 5 can also drive the baffle plate 4 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 assembly 2 from contaminating the second working surface. For example, when the cleaning equipment 100 runs on the second working surface, the baffle plate 4 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.

[0102] Optionally, the wiping component 2 can be a flat plate, a roller, a belt, etc. For example, the wiping element can be a mop, a brush, a sponge, etc. The wiping element can be detachable or non-detachable.

[0103] The wiping surface 21 can take on various shapes and sizes, such as square, rectangle, polygon, circle, ellipse, 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 wiping component.

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

[0105] The baffle 4 can take various shapes and sizes, such as square, rectangle, polygon, circle, ellipse, etc. The shape of the baffle 4 can be the same as the shape of the wiping component, or it can be different. The size of the baffle 4 can be equal to, slightly larger than, or slightly smaller than the size of the wiping component. The specific shape and size of the baffle 4 are not limited, as long as it ensures that when the cleaning equipment 100 moves to the second working surface, the wiping component will not come into contact with the second working surface under the protection of the baffle 4.

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

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

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

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

[0110] If a second working surface is detected within a first preset distance in the forward direction of the cleaning device 100, it indicates that the cleaning device 100 is about to move into the second working surface area. The first preset distance can be the distance between the front end of the cleaning device 100 in its forward direction and the edge of the second working surface, or it can be the distance between the edge of the wiping component 2 closest to the second working surface and the edge of the second working surface. When the second detection component detects that the cleaning device 100 is about to move or has already moved into the second working surface, the controller responds to the signal from the second detection component by driving the lifting component to raise the wiping component 2 and activating the drive component 5 to drive the baffle 4 to block the wiping surface 21.

[0111] If a first working surface is detected within a second preset distance in the forward direction of the cleaning device 100, it indicates that the cleaning device 100 is about to move into the first working surface area. The second preset distance can be the distance between the front end of the cleaning device 100 in its forward direction and the edge of the first working surface, or it can be the distance between the edge of the wiping component 2 closest to the first working surface and the edge of the first working surface. When the second detection component detects that the cleaning device 100 is about to move or has already moved into the first working surface, it sends a signal. The controller, in response to the signal from the second detection component, activates the drive component 5 to drive the baffle 4 to expose the wiping surface 21 and drives the wiping component 2 to descend.

[0112] According to the cleaning device 100 of the present invention, by connecting the wiping assembly 2 to the lifting assembly, the wiping assembly 2 is vertically and flexibly disposed at the bottom 11 of the device body 1. The driving assembly 5 is disposed on the device body 1 and the baffle plate 4 is connected to the driving assembly 5, so that the driving assembly 5 can drive the baffle plate 4 to move to expose the wiping surface 21, so that the wiping surface 21 can wipe the first working surface. The driving assembly 5 can also drive the baffle plate 4 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 assembly 2 from contaminating the second working surface. Furthermore, by driving the baffle plate 4 between the first position and the second position by the driving assembly 5 to make room for the lifting of the wiping assembly 2, the wiping assembly 2 can complete the lifting action more smoothly.

[0113] Reference Figure 2 , Figure 3 and Figure 5 According to some embodiments of the present invention, the device body 1 has a receiving cavity, the opening of which is located at the bottom 11 of the device body 1. The lifting assembly and the wiping assembly 2 are received within the receiving cavity, or the lifting assembly is disposed within the receiving cavity, with at least a portion of the lifting assembly passing through the opening and connected to the wiping assembly 2. By receiving the lifting assembly and the wiping assembly 2 within the receiving cavity, with at least a portion of the lifting assembly passing through the opening and connected to the wiping assembly 2, the lifting assembly is used to drive the wiping assembly 2 to be received within the receiving cavity or near the opening when the cleaning device 100 is about to move to the second working surface. That is, the lifting assembly drives the wiping assembly 2 to rise and move away from the working surface, from the extended position to the retracted position. The lifting assembly is also used to drive the wiping assembly 2 away from the opening and the receiving cavity after the cleaning device 100 has moved from the second working surface to the working surface. That is, the lifting assembly drives the wiping assembly 2 to descend and move from the retracted position to the extended position to wipe the first working surface.

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

[0115] Reference Figure 3 and Figure 5According to some embodiments of the present invention, the first position and the second position are at the same height. When the baffle 4 is in the second position, by having the first position and the second position at the same height, it can be ensured that the baffle 4 can avoid the lifting space required by the wiping assembly 2 when it moves from the first position to the second position, so as to effectively avoid interference between the baffle 4 and the wiping assembly 2, and make the wiping assembly 2 move more smoothly between the retracted position and the extended position.

[0116] For example, the movement of the shield 4 between the first position and the second position can be as follows: when the cleaning equipment 100 is cleaning an area outside the second working surface, the shield 4 is in the first position and the wiping component 2 is in the extended position; if the cleaning equipment 100 is about to move to the second working surface area, the drive component 5 drives the shield 4 to move from the first position to the second position, that is, the drive component 5 drives the shield 4 to move in a direction away from the center of the equipment body 1 to avoid the lifting space of the wiping component 2. After the lifting component drives the wiping component 2 to move upward from the extended position to the retracted position, the drive component 5 drives the shield 4 to move from the second position to the first position to block the wiping surface 21, which can effectively prevent the wiping surface 21 from being contaminated or wetted on the second working surface.

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

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

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

[0120] Reference Figure 8 , Figure 10 and Figure 12 According to some embodiments of the present invention, the avoidance structure 41 further includes a sealing structure 412, which is disposed at the avoidance opening 411 to seal the avoidance opening 411. The sealing structure 412 can avoid the connecting shaft 22 through elastic deformation or movement. In some embodiments of the present invention, the sealing structure 412 may be made of a material with water-absorbing properties to absorb sewage on the wiping surface. The sealing structure 412 disposed at the avoidance opening 411 can increase the covering area of ​​the avoidance opening 411, thereby enhancing the covering effect of the baffle plate 4 on the wiping surface. When the connecting shaft 22 contacts the sealing structure 412 at the avoidance opening 411, the sealing structure 412 can undergo elastic deformation or movement to reduce the covering area of ​​the sealing structure 412 at the avoidance opening 411, so that the connecting shaft 22 can be accommodated therein. When the connecting shaft 22 moves out of the avoidance opening 411, the sealing structure 412 can rely on its own elasticity to restore its original shape or move to a position covering the avoidance opening 411, thereby playing a role in blocking the avoidance opening 411.

[0121] Reference Figure 8 , Figure 10 and Figure 12 The sealing structure 412 includes a soft sealing sheet 4123, which can elastically deform to avoid the connecting shaft 22. When the connecting shaft 22 contacts the soft sealing sheet 4123, the soft sealing sheet 4123 can elastically deform to reduce the covering area of ​​the soft sealing sheet 4123 at the avoidance opening 411, so that the connecting shaft 22 can be accommodated therein. When the connecting shaft 22 moves out of the avoidance opening 411, the soft sealing sheet 4123 can rely on its own elasticity to return to its original shape, so as to block the avoidance opening 411.

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

[0123] The first sealing piece 4121 and the second sealing piece 4122 working together to seal at least a portion of the clearance opening 411 may include the following: for example, the first sealing piece 4121 and the second sealing piece 4122 working together to seal the clearance opening 411; or, for another example, the first sealing piece 4121 and the second sealing piece 4122 working together to seal a portion of the clearance opening 411.

[0124] For example, the first sealing sheet 4121 and / or the second sealing sheet 4122 can be integrally formed on the baffle plate 4, or can be set on the baffle plate 4 by means of bonding, adsorption connection, snap-fit ​​connection, etc.

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

[0126] In the description of this invention, "a plurality of" means two or more.

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

[0128] Reference Figure 10 and Figure 12 According to some embodiments of the present invention, both the first sealing sheet 4121 and the second sealing sheet 4122 are toothed, which can realize that the first sealing sheet 4121 and the second sealing sheet 4122 are alternately arranged in the extension direction of the relief opening 411, so that the sealing structure 412 forms a continuous sealing structure and enhances the sealing effect of the first sealing sheet 4121 and the second sealing sheet 4122 on the relief opening 411.

[0129] Reference Figure 14 According to some embodiments of the present invention, a soft sealing sheet 4123 is fixed to the inner wall of the clearance opening 411, and a clearance cut 4124 for clearance of the connecting shaft 22 is formed on the soft sealing sheet 4123. The clearance cut 4124 facilitates the accommodation of the connecting shaft 22 therein. For example, when the baffle plate 4 is in the first position and the wiping assembly 2 is in the extended position, the clearance cut 4124 can be used to clear the connecting shaft 22. During the process of the connecting shaft 22 moving relative to the baffle plate 4 into the clearance opening 411, when the connecting shaft 22 contacts the soft sealing sheet 4123 at the clearance opening 411, the soft sealing sheet 4123 can undergo elastic deformation to make the opening of the clearance cut 4124 larger, so as to facilitate the accommodation of the connecting shaft 22 therein. When the connecting shaft 22 moves out of the clearance cut 4124, the soft sealing sheet 4123 can rely on its own elasticity to restore its original shape and continue to block the clearance opening 411.

[0130] Reference Figures 15-17The sealing structure 412 includes a rigid sealing plate 4126, which is movable to cover or open the clearance opening 411. The direction of movement of the rigid sealing plate 4126 intersects the direction of movement of the baffle plate 4. When the connecting shaft 22 contacts the rigid sealing plate 4126 at the clearance opening 411, the rigid sealing plate 4126 can be moved to reduce the covering area of ​​the rigid sealing plate 4126 at the clearance opening 411, so that the connecting shaft 22 can be accommodated therein. When the connecting shaft 22 moves out of the clearance opening 411, the rigid sealing plate 4126 can move to a position to cover the clearance opening 411, so as to block the clearance opening 411.

[0131] Reference Figures 15-17 The rigid sealing sheet 4126 is connected to the baffle plate 4 by a return spring 4125. The return spring 4125 is retractable in the direction of movement of the rigid sealing sheet 4126 and is used to drive the rigid sealing sheet 4126 to move to the position of covering the clearance opening 411. When the wiping assembly 2 is in the extended position and the baffle 4 moves between the first and second positions, the connecting shaft 22 moves relative to the baffle 4. During the process of the connecting shaft 22 moving relative to the baffle 4 into the clearance opening 411, the connecting shaft 22 contacts the hard sealing sheet 4126 at the clearance opening 411 to generate a squeezing force on the hard sealing sheet 4126. This squeezing force can overcome the elastic force of the return spring 4125. At this time, the return spring 4125 is in a compressed state, causing the hard sealing sheet 4126 to move away from the clearance opening 411 to reduce the area of ​​the clearance opening 411, so that the connecting shaft 22 can be accommodated in the clearance opening 411. When the connecting shaft 22 moves out of the clearance opening 411, the hard sealing sheet 4126 moves to the position of covering the clearance opening 411 under the elastic restoring force of the return spring 4125, so as to block the clearance opening 411.

[0132] Reference Figures 15-17 The rigid sealing sheet 4126 has a first guide side 4127 and a second guide side 4128 formed on opposite sides along the movement direction of the baffle plate 4. The first guide side 4127 and the second guide side 4128 intersect the movement direction of the baffle plate 4 and the movement direction of the rigid sealing sheet 4126. The first guide side 4127 and the second guide side 4128 can guide the process of the connecting shaft 22 moving into the clearance opening 411 and the process of the connecting shaft 22 moving out of the clearance opening 411. The connecting shaft 22 can squeeze the rigid sealing sheet 4126 with a small driving force so that the rigid sealing sheet 4126 moves away from the clearance opening 411, thereby allowing the connecting shaft 22 to move more smoothly into or out of the clearance opening 411.

[0133] Reference Figure 8 , Figure 10 and Figure 12 According to some embodiments of the present invention, the clearance opening 411 includes a first clearance area 4113 and a second clearance area 4114 arranged along the extension direction of the clearance opening 411. The first clearance area 4113 is provided with a sealing structure 412. When the baffle plate 4 is in the first position and the wiping assembly 2 is in the extended position, the connecting shaft 22 passes through the second clearance area 4114. When the wiping assembly 2 is in the extended position and the baffle plate 4 is in the first position, the connecting shaft 22 passing through the second clearance area 4114 allows the wiping surface 21 to be exposed for wiping the first working surface, and allows the baffle plate 4 and the wiping assembly 2 to be closely arranged under the equipment body 1, avoiding interference between the baffle plate 4 and the wiping assembly 2.

[0134] When the wiping assembly 2 is in the extended position and the baffle 4 moves between the first and second positions, the connecting shaft 22 moves relative to the baffle 4. When the connecting shaft 22 passes through the first clearance area 4113 relative to the baffle 4, the sealing structure 412 is provided in the first clearance area 4113. When the first sealing plate 4121 and the second sealing plate 4122 come into contact with the connecting shaft 22, they can undergo elastic deformation, which can create a gap between the first sealing plate 4121 and the second sealing plate 4122 to avoid the connecting shaft 22, so that the connecting shaft 22 can pass smoothly through the first clearance area 4113. After the connecting shaft 22 moves out of the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 can return to their original shape by their own elasticity, and the first clearance area 4113 is sealed by the cooperation of the first sealing plate 4121 and the second sealing plate 4122.

[0135] For example, when the cleaning equipment 100 cleans an area outside the second working surface, the wiping component 2 is in the extended position, the baffle plate 4 is in the first position, and the connecting shaft 22 passes through the second clearance area 4114. This facilitates the wiping component 2 to wipe the first working surface while preventing interference between the baffle plate 4 and the connecting shaft 22, so that the baffle plate 4 and the wiping component 2 are closely arranged below the main body 1 of the equipment.

[0136] For example, if the cleaning equipment 100 is about to move to the second working surface, the drive assembly 5 drives the baffle 4 to move from the first position to the second position. At this time, the connecting shaft 22 moves relative to the baffle 4 from the second clearance area 4114 toward the first clearance area 4113. When the connecting shaft 22 passes through the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 undergo elastic deformation when they come into contact with the connecting shaft 22. A gap can be made between the first sealing plate 4121 and the second sealing plate 4122 to avoid the connecting shaft 22. The connecting shaft 22 moves out of the first clearance area. After 4113, the first sealing plate 4121 and the second sealing plate 4122 can return to their original shape by their own elasticity. The first avoidance area 4113 is sealed by the cooperation of the first sealing plate 4121 and the second sealing plate 4122. The baffle plate 4 moves from the first position to the second position, which can avoid the lifting space of the wiping component 2. The lifting component drives the wiping component 2 to move upward relative to the main body 1 from the extended position to the retracted position. The driving component 5 drives the baffle plate 4 to move from the second position to the first position to effectively block the wiping surface 21 and reduce or avoid the second working surface from being contaminated or wetted by the wiping component 2.

[0137] For example, if the cleaning device 100 moves from the second working surface area to the first working surface, the drive assembly 5 drives the baffle 4 to move from the first position to the second position to make way for the lifting space of the wiping assembly 2. The lifting assembly drives the wiping assembly 2 to move downward relative to the main body 1 from the retracted position to the extended position so that the wiping surface 21 can wipe the first working surface. At the same time, the drive assembly 5 drives the baffle 4 to move from the second position to the first position. At this time, the connecting shaft 22 moves relative to the baffle 4 from the first clearance area 4113 toward the second clearance area. 4114 moves, and when the connecting shaft 22 passes through the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 undergo elastic deformation when they come into contact with the connecting shaft 22, which can create a gap between the first sealing plate 4121 and the second sealing plate 4122 to avoid the connecting shaft 22. After the connecting shaft 22 moves out of the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 can return to their original shape by their own elasticity, and the connecting shaft 22 passes through the second clearance area 4114.

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

[0139] For example, when the wiping assembly 2 is in the retracted position and the shield 4 is in the first position, the wiping assembly 2 is located on the side of the shield 4 facing the main body 1. The baffle 42, located on the upper side of the shield 4 and extending circumferentially along the shield 4, enhances the shielding effect of the shield 4 on the wiping assembly 2, improving the aesthetics of the cleaning equipment 100. Furthermore, when the wiping assembly 2 is on the side of the shield 4 facing the main body 1, the shield 4 can catch water falling from the wiping assembly 2. The baffle 42, extending axially along the shield 4, increases the circumferential height of the shield 4, thereby reducing the possibility of water accumulating on the shield 4 flowing directly to the surface to be cleaned via the outer edge of the shield 4.

[0140] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the shield 4 is slidable between a first position and a second position, both of which are located below the main body 1 of the device. The shield 4 is slidable between the first position and the second position, so that the shield 4 is telescopically disposed at the bottom 11 of the main body 1 of the device. The shield 4 moves between the first position and the second position by sliding. In this way, the drive component 5 used to drive the shield 4 to slide has a simple structure and small size, and the shield 4 requires less space to move, which is beneficial to the layout optimization and miniaturization of the cleaning device 100.

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

[0142] Reference Figure 10 and Figure 11 According to some embodiments of the present invention, the transmission mechanism 52 and the transmission bar 43 are in frictional engagement. The drive motor 51 and the transmission bar 43 are connected by the transmission mechanism 52 and the transmission bar 43 in a frictional engagement manner, so that when the drive motor 51 drives the transmission mechanism 52 to move, the friction between the transmission mechanism 52 and the transmission bar 43 drives the transmission bar 43 to move, thereby driving the baffle plate 4 to slide.

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

[0144] With guide wheels 522 and drive wheels 521 located on both sides of the width direction of the transmission bar 43, the frictional engagement between drive wheels 521 and transmission bar 43, and the engagement between guide wheels 522 and transmission bar 43, can provide guidance for the transmission bar 43, thereby enabling the transmission bar 43 to slide stably relative to the equipment body between the first and second positions under this guidance. Furthermore, with guide wheels 522 and drive wheels 521 located on both sides of the width direction of the transmission bar 43, and the transmission bar 43 located within the gap between guide wheels 522 and drive wheels 521, the tight engagement between guide wheels 522 and drive wheels 521 and the transmission bar 43 helps to improve the guiding accuracy of the transmission bar 43 during the sliding process, avoids unnecessary deviation of the transmission bar 43, and improves the stability of the baffle plate 4.

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

[0146] For example, the outer periphery of the drive wheel 521 and the guide wheel 522 can be made of rubber. Rubber has good elasticity. When the transmission bar 43 is located between the guide wheel 522 and the drive wheel 521, for example, when there is a small gap between the transmission bar 43 and the guide wheel 522 or the drive wheel 521, the rubber can fill this gap between the transmission bar 43 and the guide wheel 522 and between the transmission bar 43 and the drive wheel 521 to enhance the frictional engagement effect between the transmission bar 43 and the guide wheel 522 and between the transmission bar 43 and the drive wheel 521.

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

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

[0149] Reference Figure 10 and Figure 12 According to some embodiments of the present invention, the main body 1 of the device is provided with a slide rail extending along the movement direction of the baffle plate 4, and the baffle plate 4 is provided with a mating rod 44 extending along the movement direction of the baffle plate 4. The mating rod 44 and the slide rail are slidably engaged along the movement direction of the baffle plate 4. Through the engagement of the mating rod 44 and the slide rail, the movement of the mating rod 44 can be guided and limited, ensuring that the mating rod 44 moves along a set direction and a set trajectory, and preventing the baffle plate 4 from deviating during the sliding process.

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

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

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

[0153] Reference Figure 26 , Figure 27 and Figure 30 According to some embodiments of the present invention, in the direction from the first end 61 to the second end 62, the number of the plurality of sliding rods 63 increases sequentially. The sliding rod 63 with the lower number of the adjacent two sliding rods 63 is provided with a retainer 635, and a ball bearing 634 is provided on the retainer 635. The sliding rod 63 with the higher number of the adjacent two sliding rods 63 has a mating surface 636 that cooperates with the ball bearing 634. The mating surface 636 extends along the movement direction of the baffle plate 4. The sliding rod 63 with the higher number of the adjacent two sliding rods 63 is provided with a limiting protrusion 637. In the movement direction of the baffle plate 4, the limiting protrusion 637 is located on the side of the mating surface 636 closer to the first end 61. The cage 635 supports and fixes the ball 634. When two adjacent sliding rods 63 move relative to each other, the ball 634 contacts the mating surface 636, reducing the friction between the ball 634 and the mating surface 636 and increasing the smoothness of the relative sliding, thus making the slide of the baffle 4 smoother. The limiting protrusion 637 limits the relative sliding between two adjacent sliding rods 63, ensuring that the two adjacent sliding rods 63 slide along a set direction and a set trajectory, preventing one sliding rod 63 from disengaging from the other during sliding.

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

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

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

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

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

[0159] For example, the sliding rod end cap 638 and the first sliding rod 631 can be snap-fit ​​connected, which makes the connection between the sliding rod end cap 638 and the first sliding rod 631 simple and has strong stability.

[0160] Reference Figures 34-36 According to some embodiments of the present invention, the telescopic member 6 includes a linkage telescopic mechanism 64, which includes a plurality of hingedly connected links 641. The plurality of hingedly connected links 641 form the linkage telescopic mechanism 64, and the movement of the baffle 4 between a first position and a second position can be achieved by changing the length and angle of the linkage telescopic mechanism 64.

[0161] Reference Figures 36-39 According to some embodiments of the present invention, multiple links 641 are divided into multiple groups of links 642, which are arranged along the movement direction of the baffle plate 4. Each group of links 642 includes two intersecting links 641 that are hinged together. The two links 641 of adjacent groups of links 642 are respectively hinged together. In this way, the baffle plate 4 can be moved by changing the length and angle between the two links 641 in each group of links 642, or by changing the length and angle between the two links 641 in adjacent groups of links 642, or by changing the length and angle between the two links 641 in each group of links 642 and between the two links 641 in adjacent groups of links 642.

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

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

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

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

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

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

[0168] When the baffle 4 is in the first position and the wiping assembly 2 is in the extended position, the wiping surface 21 is exposed. When the baffle 4 is in the first position and the wiping assembly 2 is in the retracted position, the baffle 4 covers the wiping surface 21. When the baffle 4 is in the second position, the baffle 4 is used to allow space for the lifting and lowering of the wiping assembly 2. Both the first and second positions are located below the main body 1 of the equipment. The main body 1 of the equipment is provided with a slide rail extending along the movement direction of the baffle 4, and the baffle 4 is provided with a mating rod 44 extending along the movement direction of the baffle 4. The mating rod 44 and the slide rail slide together along the movement direction of the baffle 4.

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

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

[0171] There are multiple first sealing pieces 4121 and second sealing pieces 4122. Both the first sealing pieces 4121 and the second sealing pieces 4122 are toothed. The first sealing pieces 4121 and the second sealing pieces 4122 are arranged alternately in the extension direction of the clearance opening 411.

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

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

[0174] For example, when the cleaning equipment 100 is cleaning an area outside the second working surface, the wiping component 2 is in the extended position, the baffle plate 4 is in the first position, and the connecting shaft 22 passes through the second clearance area 4114. This facilitates the wiping component 2 to wipe the first working surface while preventing interference between the baffle plate 4 and the connecting shaft 22, so that the baffle plate 4 and the wiping component 2 are closely arranged under the equipment body 1.

[0175] For example, if the cleaning equipment 100 is about to move to the second working surface, the drive motor 51 drives the transmission bar 43 via the drive wheel 521 and guide wheel 522 to move the baffle plate 4 from the first position to the second position. At this time, the connecting shaft 22 moves relative to the baffle plate 4 from the second clearance area 4114 toward the first clearance area 4113. When the connecting shaft 22 passes through the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 undergo elastic deformation when they contact the connecting shaft 22, creating a gap between the first sealing plate 4121 and the second sealing plate 4122 to allow the connecting shaft 22 to pass. After the connecting shaft 22 moves out of the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 can return to their original state by their own elasticity. The first clearance area 4113 is sealed by the cooperation of the first sealing plate 4121 and the second sealing plate 4122. The baffle plate 4 moves from the first position to the second position, which can make way for the lifting space of the wiping component 2. The lifting component drives the wiping component 2 to move upward relative to the main body 1 from the extended position to the retracted position. The driving component 5 drives the baffle plate 4 to move from the second position to the first position to effectively cover the wiping surface 21 and reduce or avoid the second working surface from being contaminated or wetted by the wiping component 2.

[0176] For example, if the cleaning equipment 100 moves from the second working surface area to the first working surface, the drive motor 51 drives the transmission bar 43 via the drive wheel 521 and guide wheel 522 to move the baffle plate 4 from the first position to the second position, so as to make way for the lifting space of the wiping assembly 2. The lifting assembly drives the wiping assembly 2 to move downward relative to the main body 1 from the retracted position to the extended position, so that the wiping surface 21 can wipe the first working surface. At this time, the connecting shaft 22... As the shield 4 moves from the first clearance area 4113 toward the second clearance area 4114, when the connecting shaft 22 passes through the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 undergo elastic deformation when they come into contact with the connecting shaft 22, creating a gap between the first sealing plate 4121 and the second sealing plate 4122 to allow the connecting shaft 22 to pass. After the connecting shaft 22 moves out of the first clearance area 4113, the first sealing plate 4121 and the second sealing plate 4122 can return to their original shape by their own elasticity, and the connecting shaft 22 passes through the second clearance area 4114.

[0177] Next, we will refer to Figure 12 and Figure 13 Cleaning apparatus 100 according to other embodiments of the present invention will be described.

The transmission mechanism 52 includes a first transmission wheel 523 and a second transmission wheel 524. The first transmission wheel 523 is connected to the output shaft 511 of the drive motor 51, and meshes with the second transmission wheel 524. The second transmission wheel 524 meshes with the transmission bar 43. The drive assembly 5 includes a drive bracket 53, which is mounted on the main body 1 of the equipment. The drive motor 51 is mounted on the drive bracket 53. The drive bracket 53 can support and fix the drive motor 51. When the drive motor 51 drives the first transmission wheel 523 to rotate, the first transmission wheel 523 can drive the transmission bar 43 to move via the second transmission wheel 524, thereby driving the baffle plate 4 to slide between a first position and a second position.

The first end 61 is connected to the equipment body 1, and the second end 62 is connected to the baffle 4. The length of the telescopic member 6 in the direction of movement of the baffle 4 is variable. The telescopic member 6 includes a plurality of sliding rods 63 arranged along the direction of movement of the baffle 4, and adjacent sliding rods 63 are slidable between each other in the direction of movement of the baffle 4.

[0181] At least one of two adjacent sliding rods 63 is provided with a ball bearing 634, and the two adjacent sliding rods 63 are adapted to contact each other through the ball bearing 634. In the direction from the first end 61 to the second end 62, the number of stages of the plurality of sliding rods 63 increases sequentially. A retainer 635 is provided inside the lower-stage sliding rod 63 of the two adjacent sliding rods 63, and the ball bearing 634 is provided on the retainer 635. The higher-stage sliding rod 63 of the two adjacent sliding rods 63 has a mating surface 636 that mates with the ball bearing 634. The mating surface 636 extends along the movement direction of the baffle plate 4. A limiting protrusion 637 is provided on the higher-stage sliding rod 63 of the two adjacent sliding rods 63, and in the movement direction of the baffle plate 4, the limiting protrusion 637 is located on the side of the mating surface 636 closer to the first end 61. The mating surface 636 is formed as an arc-shaped concave surface.

[0182] The telescopic component 6 includes three sliding rods 63, which are a first sliding rod 631, a second sliding rod 632, and a third sliding rod 633 arranged sequentially along the movement direction of the baffle plate 4. The first sliding rod 631 has a first end 61, and the third sliding rod 633 has a second end 62. The length of the first sliding rod 631 is S, and the maximum dimension of the wiping assembly 2 in the movement direction of the baffle plate 4 is D. S and D satisfy: 0.4D <S<1.2D。

[0183] The maximum stroke of the baffle 4 is L, and the maximum dimension of the wiping assembly 2 in the direction of movement of the baffle 4 is D. L and D satisfy: D <L<1.4D。

[0184] Next, we will refer to Figures 32-39 A cleaning device 100 according to further embodiments of the present invention will be described. In this embodiment, the parts that are the same as those in the above embodiments will not be described again, and reference can be made to the above embodiments. The main difference from the above embodiments will be described.

[0185] The telescopic component 6 includes a linkage telescopic mechanism 64, which includes multiple hinged links 641. The multiple links 641 are divided into multiple groups of links 642, which are arranged along the movement direction of the baffle plate 4. Each group of links 642 includes two intersecting and hinged links 641, and the two links 641 of two adjacent groups of links 642 are respectively hinged.

[0186] Reference Figures 1-3 According to a second aspect of the present invention, a 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 described above. The cleaning device 100 is adapted to cooperate with the cleaning base station, which is used to clean and / or charge the cleaning device 100.

[0187] According to the cleaning system of the present invention, by providing the above-mentioned cleaning device 100, the wiping component 2 of the cleaning device 100 is connected to the lifting component, so that the wiping component 2 is elliptically disposed at the bottom 11 of the device body 1. The driving component 5 is disposed on the device body 1 and the baffle plate 4 is connected to the driving component 5, so that the driving component 5 can drive the baffle plate 4 to move to expose the wiping surface 21, so that the wiping surface 21 can wipe the first working surface. The driving component 5 can also drive the baffle plate 4 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 component 2 from contaminating the second working surface. Furthermore, by driving the baffle plate 4 to move between the first position and the second position by the driving component 5 to avoid the lifting space of the wiping component 2, the wiping component 2 can complete the lifting action more smoothly.
