Description

[0001] This application claims priority to Chinese patent application No. 2026104327000, filed on April 2, 2026, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning equipment, and more particularly to a cleaning device and a cleaning device component. Background Technology

[0003] With the increasing popularity of smart homes, window cleaning robots are becoming more and more popular among users.

[0004] Window cleaning robots typically integrate a walking mechanism. The tracks of this mechanism are used to contact the glass surface to be cleaned and provide friction for the robot's movement. Therefore, ensuring sufficient grip to prevent slippage is one of the key technological goals continuously pursued by this type of product. However, in related technologies, during the cleaning process, the track grooves easily accumulate dust and water stains. This not only easily reduces the friction between the track and the surface to be cleaned, leading to slippage, but also causes secondary contamination of the cleaned area by dirt and water stains falling from the grooves, reducing the cleaning efficiency of the window cleaning robot.

[0005] Therefore, how to simultaneously enhance the friction between the track and the glass to prevent slippage and achieve self-cleaning, thereby systematically improving the product's reliability, cleaning efficiency, and user experience, has become an urgent technical problem to be solved. Summary of the Invention

[0006] In view of this, this application provides a cleaning device and a cleaning device component, which is beneficial to improve the cleanliness of tracks to at least a certain extent, can at least a certain extent avoid dust accumulation and water stains on tracks, and improve the friction between tracks and surfaces to be cleaned.

[0007] This application provides a cleaning device, comprising: a housing, one side wall of the housing along a first direction serving as a bottom plate, the bottom plate being adapted to face the surface to be cleaned, the bottom plate having a spaced-apart air inlet and air outlet; a walking device, the walking device being installed inside the housing and including a track, the track passing through the air outlet, the track having airflow holes penetrating the track along the arrangement direction of the track's outer and inner circumferential surfaces; an air duct component and a fan module, both the air duct component and the fan module being disposed inside the housing, the fan module being used to drive fluid from the air inlet into the air duct component; the air outlet of the air duct component facing the track.

[0008] In the cleaning equipment provided in this application, by directing the exhaust vent of the air duct component towards the track, the airflow from the exhaust vent directly sweeps the track surface, removing accumulated dirt and drying water stains. This avoids a decrease in friction between the track and the surface to be cleaned, prevents secondary contamination of the cleaned surface, improves the self-cleaning ability of the cleaning equipment, and enhances its cleaning efficiency, product reliability, and user experience. Furthermore, the airflow holes on the track allow a portion of the high-speed airflow from the exhaust vent to pass through the airflow holes in the track section furthest from the bottom plate and act on the track section in contact with the surface to be cleaned. This "penetrating" action reduces intermediate links in force transmission, more directly enhancing the local pressure in the contact area, improving the anti-slip effect, and simultaneously enhancing the ability to remove stubborn dirt from the track.

[0009] In one possible implementation of this application, the outer peripheral surface of the track has track grooves, and airflow holes are located at the track grooves. This design does not reduce the contact area between the outer peripheral surface of the track and the surface to be cleaned, thus ensuring the friction between the two.

This cleaning device is used for moving and cleaning on vertical or inclined surfaces such as glass, and can also be used on horizontal surfaces.

[0074] Please see Figure 1 and Figure 2 , Figure 1 A perspective view of the cleaning equipment 100 provided in this application. Figure 2 According to Figure 1 An exploded view of the cleaning equipment 100 shown. Figure 1 and Figure 2 This description uses a window cleaning robot as an example of the cleaning equipment 100, and should not be construed as a specific limitation on this application. Specifically, the cleaning equipment 100 provided in this application may include a housing 1, a walking device 2, an air duct component 3, and a fan module 4.

[0075] Understandable Figure 1 and Figure 2 The cleaning device 100 is shown only schematically, and the specific construction, shape, and size of these components are not subject to change. Figure 1 and Figure 2 And the limitations of the figures below.

[0076] The housing 1 is used to integrate the walking device 2, the air duct component 3, and the fan module 4, etc. The material of the housing 1 includes, but is not limited to, plastic, metal, or a combination of both. The shape of the housing 1 includes, but is not limited to, a cube, a cylinder, or an irregular shape.

[0077] Please continue reading. Figure 1 and Figure 2 The housing 1 has a bottom plate 11 and a top plate 12. The bottom plate 11 is a plate in the housing 1 that faces the surface to be cleaned.

[0078] The base plate 11 has an air inlet 111 and an air outlet 112. The air inlet 111 and the air outlet 112 are spaced apart. The air inlet 111 is used to draw in outside air to generate a negative pressure adsorption force inside the cleaning device 100, so that the cleaning device 100 can adhere to the surface to be cleaned. The air outlet 112 is used to partially expose the walking device 2 so that it can contact the surface to be cleaned.

[0079] The air inlet 111 can be defined by a plurality of spaced-apart holes or by a single opening. This application does not impose specific limitations in this regard. When the air inlet 111 is defined by holes, the shape of the holes includes, but is not limited to, circles, rectangles, triangles, hexagons, or irregular shapes. When the air inlet 111 is an opening, the shape of the opening includes, but is not limited to, circles, rectangles, triangles, hexagons, or irregular shapes. For example, when the air inlet 111 is an opening, a grille can be provided at the opening.

[0080] The opening shape of the air outlet 112 includes, but is not limited to, a circle, a rectangle, a triangle, a hexagon, or an irregular shape.

[0081] The top plate 12 and the bottom plate 11 are arranged opposite each other along the first direction F1, that is, the top plate 12 is located on the side of the bottom plate 11 away from the surface to be cleaned. The first direction F1 is parallel to the normal of the surface to be cleaned.

[0082] For example, please continue reading Figure 1 and Figure 2 A handle 122 may be provided on the outer surface of the top plate 12 so that the user can hold the handle 122 to pick up and put down the cleaning equipment 100.

[0083] The housing 1 may also include a side frame 13, which surrounds the top plate 12 and the bottom plate 11. The side frame 13 may be connected to the top plate 12 by means of snap-fit, adhesive, welding or screw connection, or it may be integrally formed. The side frame 13 may be connected to the bottom plate 11 by means of snap-fit, adhesive, welding or screw connection, or it may be integrally formed.

[0084] The fan module 4 is installed inside the housing 1. The installation methods of the fan module 4 inside the housing 1 include, but are not limited to, snap-fit, adhesive, welding or screw connection. The inlet of the fan module 4 is usually connected to the air inlet 111 to provide airflow power, driving air to flow from the air inlet 111 into the cleaning device 100, so as to provide the negative pressure adsorption function of the cleaning device 100 on the surface to be cleaned.

[0085] The core function of the walking device 2 is to provide driving force for the movement of the cleaning equipment 100 on the surface to be cleaned. The walking device 2 is installed as a modular unit inside the housing 1 and is arranged corresponding to the air outlet 112 on the base plate 11.

[0086] Please see Figure 3 , Figure 4 and Figure 5 , Figure 3 According to Figure 1 A perspective view of a portion of the structure of the cleaning equipment 100 shown, wherein the top plate 12 is not shown; Figure 4 According to Figure 3 The structure shown is a cross-sectional view at line AA; Figure 5 According to Figure 3 The structure shown is a cross-sectional view at line BB. The running gear 2 may include: a mounting compartment 21, multiple drive hubs 22, and tracks 23.

[0087] The installation compartment 21 may be made of materials including but not limited to plastic, metal, or a combination of both.

[0088] The mounting compartment 21 is a shell-like structure with a specific internal space. The mounting compartment 21 is located within the housing 1. For example, the mounting compartment 21 is mounted on the base plate 11. The mounting compartment 21 and the housing 1 can be detachably connected, for example, by bolts, snap-fit, or magnetic attraction. This facilitates the detachable arrangement of the walking device 2 relative to the housing 1, thereby simplifying maintenance and replacement and reducing maintenance costs. Alternatively, the mounting compartment 21 and the housing 1 can be non-detachably connected, for example, by welding or adhesive bonding. This design improves the connection strength between the mounting compartment 21 and the housing 1.

[0089] The side of the mounting compartment 21 facing the base plate 11 is open, and this open area is directly opposite to and connected to the air outlet 112 on the base plate 11, that is, the side of the mounting compartment 21 facing the air outlet 112 is open. This allows the interior space of the mounting compartment 21 to communicate with the external environment of the cleaning equipment 100 through this open area and the air outlet 112.

[0090] The wall panel of the mounting compartment 21 away from the base plate 11 has a communication opening 211. The opening shape of the communication opening 211 includes, but is not limited to, circles, rectangles, triangles, hexagons, or irregular shapes.

[0091] Multiple drive hubs 22 are spaced apart along the second direction F2. Here, the number of drive hubs 22 can be two, but in other examples, it can also be three, four, or five.

[0092] Each drive hub 22 is rotatably mounted within the mounting chamber 21. Thus, the second direction F2 is the direction of movement of the cleaning device 100, such as the forward or backward direction.

[0093] The second direction F2 is perpendicular to the first direction F1. The direction perpendicular to both the first direction F1 and the second direction F2 is the third direction F3. For example, the extension direction of the rotation center line of the aforementioned drive hub 22 is the third direction F3.

[0094] For example, the first direction F1 is the thickness direction of the shell 1, the second direction F2 is the width direction of the shell 1, and the third direction F3 is the length direction of the shell 1. As another example, the first direction F1 is the thickness direction of the shell 1, the second direction F2 is the length direction of the shell 1, and the third direction F3 is the width direction of the shell 1.

[0095] The drive hub 22 can be directly driven to rotate by a motor, or it can be indirectly driven by a motor through a transmission mechanism such as a gear or synchronous belt between the motor and the drive hub 22.

[0096] The track 23 is fitted around the outer periphery of the aforementioned plurality of drive hubs 22, forming a closed loop. For example, track teeth are formed on the inner circumferential surface of the track 23, and hub teeth are formed on the drive hubs 22, which mesh with the track teeth. When the drive hubs 22 rotate, they drive the track 23 to circulate.

[0097] The track 23 passes through the air outlet 112, meaning that a section of the track 23 protrudes from the opening at the bottom of the mounting compartment 21 and the corresponding air outlet 112, thus allowing direct contact with the surface to be cleaned. The cleaning equipment 100 is moved as a whole by the friction between the track 23 and the surface to be cleaned.

[0098] For example, the outer circumferential surface of track 23 is usually provided with track grooves to enhance traction.

[0099] Based on the above description, in the cleaning equipment 100 provided in this application, by including the mounting compartment 21, drive hub 22, and track 23 in the walking device 2, the drive hub 22 and track 23 can be installed inside the mounting compartment 21, thereby facilitating the assembly of the walking device 2 as a whole with the housing 1, which reduces the assembly difficulty of the cleaning equipment 100. Of course, it is understood that in other examples, the mounting compartment 21 may not be provided in the walking device 2, and the track 23 and drive hub 22 may be directly installed inside the housing 1.

[0100] The traveling device 2 and the fan module 4 are spaced apart along the third direction F3. The duct component 3, a key component for guiding and regulating the airflow path, is also installed inside the housing 1. The duct component 3 is located on the side of the fan module 4 facing away from the base plate 11, and on the side of the traveling device 2 facing away from the base plate 11. In this way, the duct component 3 is stacked with the fan module 4 and the traveling device 2 in the first direction F1. This allows for a reduction in the overall size of the duct component 3, fan module 4, and traveling device 2 along the second direction F2 and the third direction F3, thereby reducing the circumferential size of the cleaning equipment 100.

[0101] Of course, it is understandable that in other examples, the traveling device 2 and the fan module 4 may also be distributed at a distance along the second direction F2, or distributed along the first direction F1. The duct component 3 and the fan module 4 may also be distributed along the second direction F2, or distributed along the third direction F3. For ease of explanation, the following description will use the example of the traveling device 2 and the fan module 4 being distributed at a distance along the third direction F3, with the duct component 3 located on the side of the fan module 4 facing away from the base plate 11, and also on the side of the traveling device 2 facing away from the base plate 11.

[0102] Please continue reading. Figure 3 , Figure 4 and Figure 5The air duct component 3 has an air inlet 33 and an air outlet 32. The opening shape of the air inlet 33 includes, but is not limited to, a circle, rectangle, ellipse, triangle, or irregular shape. The opening shape of the air outlet 32 ​​includes, but is not limited to, a circle, rectangle, ellipse, triangle, or irregular shape. The air inlet 33 of the air duct component 3 is connected to the outlet of the fan module 4. The high-speed airflow pressurized by the fan module 4 can flow into the air duct component 3 through the air inlet 33.

[0103] The exhaust port 32 of the air duct component 3 faces the track 23 and is located on the side of the mounting compartment 21 of the traveling device 2 away from the bottom plate 11. More specifically, the exhaust port 32 is directly opposite the communication port 211 of the mounting compartment 21. This design allows the exhaust port 32 of the air duct component 3 to be located on the side of the track 23 away from the bottom plate 11.

[0104] Please see Figure 6 , Figure 6 According to Figure 3 The diagram shows the vertical projection relationship between the track 23 and the exhaust port 32 of the air duct component 3 on a plane V1 parallel to the base plate 11. Within the plane V1 parallel to the base plate 11, the vertical projection of the exhaust port 32 overlaps with the vertical projection of the track 23. When the blower module 4 is started, external air is drawn in through the air inlet 111 of the base plate 11 and pressurized by the blower module 4 to form a high-speed airflow. This high-speed airflow first enters the air duct component 3 and exits through its exhaust port 32. Because the exhaust port 32 is directly opposite the connecting opening 211 of the mounting compartment 21, and because the vertical projection of the exhaust port 32 overlaps with the vertical projection of the track 23 within the plane V1 parallel to the base plate 11, the airflow can enter the interior space of the mounting compartment 21 almost without loss, perpendicularly towards the track 23, and directly act on the track 23 within the mounting compartment 21. This airflow perpendicular to the track 23 generates a continuous pressure on the track 23. This pressure is transmitted through the track 23 to the part of it in contact with the surface to be cleaned, which is equivalent to increasing the normal clamping force of the track 23 on the surface to be cleaned. The increased normal clamping force is directly converted into a larger effective adhesion force (i.e., friction) between the track 23 and the surface to be cleaned. This significantly reduces the risk of the cleaning equipment 100 slipping on the surface to be cleaned or when inertial forces are generated due to starting, stopping, turning, etc., and improves the reliability and stability of the cleaning equipment 100's movement.

[0105] Simultaneously, the continuous high-speed airflow generates a strong shearing and sweeping effect on the surface of track 23. This effectively removes dust, sand, and other contaminants that may have become embedded in the track grooves during the cleaning process, preventing these contaminants from being re-imprinted onto the cleaned surface during subsequent movement of the cleaning equipment 100, thus effectively preventing "secondary contamination." Furthermore, the airflow quickly dries any water film or stains adhering to the surface of track 23, keeping the surface dry, which also helps maintain a stable and high coefficient of friction.

[0106] In summary, in the cleaning equipment 100 provided in this application, by setting the exhaust port 32 of the air duct component 3 towards the track 23, placing it on the side of the track 23 away from the bottom plate 11, and in a plane V1 parallel to the bottom plate 11, setting the exhaust port 32 of the air duct component 3 to have an overlapping area with the vertical projection of the track 23, the exhaust port 32 can be directly facing the track 23 along the first direction F1. The airflow pressure of the exhaust port 32 applies a vertical force to the track 23 towards the surface to be cleaned, thereby effectively enhancing the tightness of the fit between the track 23 and the surface to be cleaned, and at least to a certain extent avoiding the slippage problem when the cleaning equipment 100 moves; at the same time, the high-speed airflow directly blows the surface of the track 23, which can remove accumulated dirt and dry water stains, avoiding secondary pollution of the cleaned surface, improving the self-cleaning ability of the cleaning equipment 100, improving the cleaning efficiency of the cleaning equipment 100, the reliability of the product, and the user experience.

[0107] It is understandable that, within plane V1 parallel to the base plate 11, the overlapping area between the vertical projection of the exhaust vent 32 and the vertical projection of the track 23 includes the following situations: Situation 1: Within plane V1 parallel to the base plate 11, a portion of the vertical projection of the exhaust vent 32 overlaps with a portion of the vertical projection of the track 23. Situation 2: Within plane V1 parallel to the base plate 11, the vertical projection of the exhaust vent 32 lies within the vertical projection of the track 23. Situation 3: Within plane V1 parallel to the base plate 11, the vertical projection of the exhaust vent 32 completely coincides with the vertical projection of the track 23. Situation 4: Within plane V1 parallel to the base plate 11, the vertical projection of the track 23 lies within the vertical projection of the exhaust vent 32.

[0108] For example, please continue reading Figure 4 , Figure 5 and Figure 6 The vertical projection of the exhaust vent 32 is located between the two ends of the width direction (i.e., the third direction F3) of the vertical projection of the track 23. This design allows the high-speed airflow discharged from the exhaust vent 32 to act on the middle area of ​​the track 23 along the width direction, further enhancing the tightness of the fit between the track 23 and the surface to be cleaned, avoiding slippage, and improving the self-cleaning effect of the cleaning equipment 100.

[0109] For example, please continue reading Figure 6 Within plane V1 parallel to the base plate 11, the vertical projection of the exhaust vent 32 lies within the vertical projection of the track 23. This design allows more high-speed airflow from the exhaust vent 32 to be used on the track 23, further enhancing the tightness of the fit between the track 23 and the surface to be cleaned, preventing slippage, and improving the self-cleaning effect of the cleaning equipment 100.

[0110] For example, please continue reading Figure 6The distance d1 between the edge of the vertical projection of the exhaust vent 32 and the edge of the vertical projection of the track 23 is less than 5 mm. For example, the distance d1 between the edge of the vertical projection of the exhaust vent 32 and the edge of the vertical projection of the track 23 is 1 mm, 2 mm, 3 mm, 4 mm or 4.5 mm.

[0111] For example, please continue reading Figure 6 Within a plane V1 parallel to the base plate 11, at least a portion of the vertical projection of the exhaust vent 32 lies between the vertical projections of the rotation center lines o1 of two adjacent drive hubs 22. This means that at least a portion of the airflow avoids the solid area of ​​the drive hubs 22, instead flowing downwards from the gap between adjacent drive hubs 22, thus acting more directly on the taut track 23 section between the two drive hubs 22. This further enhances the tightness of the fit between the track 23 and the surface to be cleaned, preventing slippage and improving the self-cleaning effect of the cleaning equipment 100.

[0112] Based on this, for example, in a plane V1 parallel to the base plate 11, the portion of the vertical projection of the exhaust port 32 is located between the vertical projections of the rotation center lines o1 of two adjacent drive hubs 22.

[0113] Based on this, for example, within a plane V1 parallel to the base plate 11, the portion of the vertical projection of the exhaust vent 32 is located between two adjacent drive hubs 22. This allows for the utilization of more high-speed airflow from the exhaust vent 32 at this location, further enhancing the tightness of the fit between the track 23 and the surface to be cleaned, preventing slippage, and improving the self-cleaning effect of the cleaning equipment 100.

[0114] In related technologies, the air inlet and outlet of cleaning equipment are set too close together, causing the airflow to be directly sucked into the outlet before it has fully diffused inside the cleaning equipment. When the airflow flows through a short path, it is easy to generate high-frequency turbulence and vortices, which directly aggravates aerodynamic noise, resulting in a lot of noise and greatly affecting the user experience.

[0115] Therefore, in some embodiments, please refer to [the relevant documentation]. Figure 3 , Figure 4 and Figure 5The length direction of the duct component 3 (e.g., third direction F3) is consistent with the length direction of the housing 1. The air inlet 33 and the air outlet 32 ​​of the duct component 3 are spaced apart along the length direction of the duct component 3. In this embodiment, by using the duct component 3 to connect the fan module 4 and the traveling device 2, and by setting the length direction of the duct component 3 to be consistent with the length direction of the housing 1, and by making the air inlet 33 and the air outlet 32 ​​of the duct component 3 spaced apart along the length direction of the duct component 3, it is beneficial to maximize the dimensional advantage of the cleaning device 100 in the length direction. This allows for a relatively large spacing between the air inlet 33 and the air outlet 32, which helps to extend the flow channel length within the duct component 3. This forces the airflow to flow through a longer path inside the flow channel. The longer flow channel provides sufficient space for diffusion, deceleration, and flow field reconstruction of the high-speed, turbulent airflow discharged from the fan module 4, allowing large-scale vortices to attenuate, thereby reducing the high-frequency aerodynamic noise generated by turbulence and vortex shedding. This makes the cleaning device 100 quieter when it is working, improving the user experience.

[0116] In some embodiments, please continue Figure 4 and Figure 5 The base plate 11 has two air outlets 112, and correspondingly, there are two sets of walking devices 2. The air duct component 3 has two exhaust ports 32. Each exhaust port 32 corresponds to one set of walking devices 2 and one air outlet 112. A set of walking devices 2 is arranged on each of the opposite sides of the fan module 4 along the third direction F3. This design allows the fan module 4 to be located approximately in the middle of the housing 1 along the third direction F3. The length direction of the air duct component 3 can then be set to the third direction F3, with two exhaust ports 32 formed at each end, thereby splitting the airflow generated by the fan module 4 into two parts and guiding them evenly to the walking devices 2 on both sides. This is beneficial for the symmetrical balance of the adsorption force, adhesion force, and walking driving force on both sides of the cleaning equipment 100, and is beneficial for the straight-line movement and turning control of the equipment on the cleaning surface.

[0117] For example, the two sets of walking devices 2 are symmetrically arranged relative to the fan module 4, which can ensure the symmetrical balance of the adsorption force, adhesion force and walking driving force on both sides of the cleaning device 100, and facilitate the straight-line walking and turning control of the cleaning device 100 on the cleaning surface.

[0118] Of course, it is understandable that in other examples, there may be more than two air outlets 112, walking devices 2, and exhaust vents 32, or each may be a single unit.

[0119] In some embodiments, along the second direction F2, the two ends of the air duct component 3 are located between the two ends of the mounting chamber 21. This inclusive layout facilitates structural compactness.

[0120] For further information, please refer to [link / reference]. Figure 4And return them together Figure 2 The ratio of the width W1 of the duct component 3 along the second direction F2 to the length L1 of the mounting chamber 21 along the second direction F2 is set to be greater than or equal to 1 / 3. This ratio ensures that the duct component 3 has sufficient cross-sectional area to reduce airflow velocity and resistance, while its width is reasonably constrained by the dimensions of the mounting chamber 21, resulting in a harmonious internal layout and high space utilization.

[0121] For example, the ratio of the width dimension W1 of the air duct component 3 along the second direction F2 to the length dimension L1 of the mounting compartment 21 along the second direction F2 is set to 1 / 2 or 2 / 3.

[0122] In some embodiments, please continue reading Figure 5 The air duct component 3 contains a sound-absorbing material component 8. The material of the sound-absorbing material component 8 includes, but is not limited to, porous sound-absorbing cotton, aluminum foam, etc. This design can reduce the transmission of noise from the fan module 4 through the air duct, and the sound-absorbing material component 8 can absorb mid-to-high frequency noise by converting sound energy into heat energy.

[0123] For example, the sound-absorbing material component 8 can be located on the inner wall of the air duct component 3, directly opposite the air inlet 33. With this design, when the high-speed airflow enters the air duct component 3, it can first come into contact with the sound-absorbing material component 8, thereby improving the noise reduction effect.

[0124] For example, a positioning rib (not shown in the figure) can be provided on the inner wall surface of the air duct component 3, directly opposite the air inlet 33. The positioning rib is arranged around the outer periphery of the sound-absorbing material component 8. With this design, the sound-absorbing material component 8 can be fixed and limited using the positioning rib.

[0125] The positioning ribs can be integrally connected to the air duct component 3, or they can be connected to the air duct component 3 by means of adhesive, welding, snap-fit ​​or screw connection.

[0126] For example, the positioning ribs can be closed-loop, with the sound-absorbing material component 8 embedded within the ring-shaped positioning ribs. Alternatively, the positioning ribs can be multiple sub-ribs spaced apart along the circumference of the sound-absorbing material component 8. These multiple sub-ribs work together to clamp and limit the position of the sound-absorbing material component 8. In addition, the sound-absorbing material component 8 can also be installed within the duct component 3 using adhesive (e.g., double-sided tape or adhesive backing) or screw connections.

[0127] In some embodiments, please refer to Figure 7 , Figure 7 According to Figure 5The diagram shows an enlarged view of the portion circled at point C. A first sealing ring 7 is provided between the air duct component 3 and the mounting chamber 21. The first sealing ring 7 surrounds the exhaust port 32 and the connecting port 211. This design improves the sealing between the air duct component 3 and the mounting chamber 21, preventing air leakage and allowing more airflow to act on the track 23.

[0128] The material of the first sealing ring 7 includes, but is not limited to, elastic materials such as rubber or silicone.

[0129] For example, please continue reading Figure 7 An annular groove 212 is provided on the end face of the installation chamber 21 facing the exhaust port 32. The first sealing ring 7 is embedded in the annular groove 212 and abuts against the air duct component 3. This design allows the annular groove 212 to limit the position of the first sealing ring 7, preventing misalignment or deviation, and improving the sealing performance.

[0130] Of course, it is understandable that in other examples, the annular groove can also be opened in the area of ​​the air duct 3 surrounding the exhaust port 32. In this case, the first sealing ring 7 is embedded in the annular groove 212 and abuts against the end face of the mounting chamber 21 facing the exhaust port 32.

[0131] For example, the air duct component 3 is provided with a positioning stop 365 extending into the connection port 211. The positioning stop 365 is arranged around the exhaust port 32. This design allows the positioning stop 365 and the connection port 211 to play a pre-positioning role, thereby improving the assembly efficiency of the cleaning equipment 100.

[0132] The positioning stop 365 can be integrally connected to the air duct component 3, or it can be connected to the air duct component 3 by means of adhesive, welding, snap-fit ​​or screw 6.

[0133] Of course, it is understandable that in other examples, the positioning stop could also be located on the installation compartment 21, extending into the exhaust vent 32.

[0134] In some embodiments, please refer to Figure 8 , Figure 8 According to Figure 5 The diagram shows an enlarged view of the portion circled at point D. A second sealing ring 9 is provided between the air duct component 3 and the fan module 4, and the second sealing ring 9 is arranged around the outlet of the fan module 4 and the air inlet 33 of the air duct component 3. This design can improve the sealing between the air duct component 3 and the fan module 4, prevent air leakage, and allow more airflow to enter the air duct component 3, further facilitating more airflow to act on the track 23.

[0135] The material of the second sealing ring 9 includes, but is not limited to, flexible materials such as rubber or silicone.

[0136] For example, please continue reading Figure 8 A first groove 91 is formed on one end face of the second sealing ring 9 along its axial direction, and a second groove 92 is formed on the other end face of the second sealing ring 9 along its axial direction.

[0137] The surface of the air duct component 3 facing the fan module 4 is provided with a first retaining rib 34. The first retaining rib 34 can be integrally set on the air duct component 3, or it can be connected to the air duct component 3 by means of adhesive, welding, snap-fit ​​or screw connection. The first retaining rib 34 is interference-fitted into the first retaining groove 91.

[0138] A ring-shaped support platform 42 is provided on the outer peripheral surface of the fan module 4. A second retaining rib 421 is provided on the ring-shaped support platform 42, and the second retaining rib 421 is interference-fitted into a second retaining groove 92. The ring-shaped support platform 42 can be integrally connected to the outer wall of the fan module 4, or it can be connected by means of adhesive bonding, welding, snap-fitting, or screw connection. The second retaining rib 421 and the ring-shaped support platform 42 can be integrally connected, or they can be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[0139] In the embodiments of this application, by respectively providing a first slot 91 and a second slot 92 on the second sealing ring 9, and utilizing the first retaining rib 34 provided on the air duct component 3 to cooperate with the first slot 91, and utilizing the second retaining rib 421 provided on the fan module 4 to cooperate with the second slot 92, this multi-slot retaining rib cooperation structure can make the second sealing ring 9 firmly pre-fixed between the air duct component 3 and the fan module 4, which can not only reliably resist the vibration and noise of the fan module 4, but also prevent misalignment and detachment during the assembly of the air duct component 3 and the fan module 4, thus ensuring the reliability of the seal.

[0140] To further limit the radial movement of the second sealing ring 9, in some embodiments, please refer to... Figure 8 A first limiting rib 35 is protruding from the surface of the duct component 3 facing the fan module 4. The first limiting rib 35 can be integrally set on the duct component 3, or it can be connected to the duct component 3 by means of adhesive, welding, snap-fit ​​or screw connection. The first limiting rib 35 is located on the inner circumference side of the second sealing ring 9 and stops its inner edge.

[0141] To further limit the radial movement of the second sealing ring 9, in some embodiments, please refer to [the relevant documentation]. Figure 8 A second limiting rib 43 is formed on the fan module 4. The second limiting rib 43 can be integrally set on the fan module 4, or it can be connected to the fan module 4 by means of adhesive bonding, welding, snap-fit, or screw connection. The second limiting rib 43 is located on the inner circumference of the second sealing ring 9 and stops its inner edge.

[0142] Please return to the reference. Figure 3 , Figure 4 and Figure 5 The air duct component 3 has clearance notches 31 formed on both sides of its second direction F2 (e.g., the width direction of the air duct component 3). Of course, in other examples, clearance notches 31 can be formed on one side of the air duct component 3 along the second direction F2, as long as clearance notches 31 are formed on at least one side of the air duct component 3 along the second direction F2.

[0143] For example, the clearance notches 31 on both sides of the duct component 3 along the second direction F2 can be staggered along the third direction F3 (e.g., the length direction of the duct component 3). This arrangement not only helps to ensure the structural strength of the duct component 3, but also helps to increase the cross-sectional area of ​​the flow channel inside the duct component 3, and avoids the clearance notches 31 on both sides of the duct component 3 being directly opposite each other in the second direction F2, which would result in the size being too small and affecting the air guiding effect of the duct component 3.

[0144] For example, along the third direction F3, the clearance gap 31 is located between the fan module 4 and the traveling device 2. Furthermore, for a scheme where there are two sets of traveling devices 2, the clearance gap 31 on one side edge of the duct component 3 along the second direction F2 is located between one of the traveling devices 2 and the fan module 4, and the clearance gap 31 on the other side edge is located between the other traveling device 2 and the fan module 4.

[0145] With this design, an avoidance gap 31 is set in the area between the walking device 2 and the fan module 4 of the air duct component 3, which makes it easier to avoid the internal structure of the housing 1 and avoids mutual interference between the internal structure of the housing 1 and the fan module 4 and the walking device 2.

[0146] Please see Figure 9 , Figure 10 and Figure 11 , Figure 9 According to Figure 1 The structure shown is a cross-sectional view at EE. Figure 10 According to Figure 9 The structure shown is an enlarged view of the circled portion at point G. Figure 11 According to Figure 3 The diagram shows an enlarged view of the portion circled at point F. A first connecting post 121 protruding towards the base plate 11 is provided on the inner surface of the top plate 12. The first connecting post 121 can be integrally connected to the top plate 12, or it can be connected to the top plate 12 by means of adhesive bonding, welding, snap-fitting, or screw connection.

[0147] The inner surface of the base plate 11 is provided with a second connecting post 113 protruding in the direction of the top plate 12. The second connecting post 113 can be integrally connected to the base plate 11, or it can be connected to the base plate 11 by means of adhesive, welding, snap-fit ​​or screw connection.

[0148] The first connecting column 121 and the second connecting column 113 are detachably connected. In plane V1 parallel to the base plate 11, the vertical projections of the first connecting column 121 and the second connecting column 113 are both located within the vertical projection area of ​​the clearance notch 31 on the side of the air duct component 3. This means that the first connecting column 121 and the second connecting column 113 are completely accommodated within the clearance notch 31 of the air duct component 3. This design not only avoids affecting the assembly of the housing 1 and prevents interference between the connecting columns and the air duct component 3, but also eliminates the need to design the outer dimensions of the housing 1 to be excessively large in order to avoid interference, thus preventing an increase in the volume of the housing 1. Furthermore, it helps to improve the utilization rate of the internal space of the housing 1 and enhance the compactness of the structure.

[0149] For example, the first connecting post 121 and the second connecting post 113 are detachably connected by screws. For instance, the base plate 11 and the second connecting post 113 are integrally formed with a fastening hole 1131 penetrating both the base plate 11 and the second connecting post 113. One end of the first connecting post 121 facing the base plate 11 has an internally threaded hole 1211. A portion of the first connecting post 121 is located within the fastening hole 1131. A screw 6 is inserted into the fastening hole 1131 from one side of the base plate 11 towards the other side of the top plate 12, and threadedly engages with the internally threaded hole 1211 on the first connecting post 121.

[0150] For example, an annular limiting rib 11311 is provided on the inner circumferential surface of the fastening hole 1131, and the first connecting post 121 abuts against the annular limiting rib 11311. With this design, the annular limiting rib 11311 can be used to guide the alignment of the top plate 12 and the bottom plate 11 during assembly, which can improve the assembly efficiency of the cleaning equipment 100.

[0151] Since the base plate 11 faces the surface to be cleaned during use, the base plate 11 has high load-bearing requirements. Therefore, to enhance the structural rigidity of the second connecting column 113 by opening a hole in it, a first reinforcing rib 114 can be provided on the inner surface of the base plate 11. This first reinforcing rib 114 is connected to the outer peripheral surface of the second connecting column 113, serving as a rib support. Alternatively, a second reinforcing rib (not shown) can be provided on the inner surface of the top plate 12, connected to the outer peripheral surface of the first connecting column 121.

[0152] For example, the inner circumferential surface of the clearance notch 31 can be an arc-shaped surface, which helps to reduce stress concentration and improve the strength and fatigue life of the air duct component 3 structure at the clearance notch 31. In other examples, the inner circumferential surface of the clearance notch 31 can also be defined by multiple intersecting planes, or the inner circumferential surface of the clearance notch 31 can be an elliptical arc-shaped surface.

[0153] For example, please continue reading Figure 10 and Figure 11The inner surface of the base plate 11 is provided with a protrusion 115. The protrusion 115 can be integrally connected to the base plate 11, or it can be connected to the base plate 11 by means of adhesive, welding, snap-fit ​​or screw connection.

[0154] A protruding plate 36 is provided on the inner circumferential surface of the clearance notch 31. The protruding plate 36 can be integrally connected to the air duct component 3, or it can be connected to the air duct component 3 by means of adhesive, welding, snap-fit ​​or screw connection.

[0155] The protruding post 115 and the protruding plate 36 are connected in a detachable manner (e.g., screw connection, snap-fit ​​connection) to fix the air duct component 3 to the housing 1.

[0156] Within plane V1 parallel to the base plate 11, the vertical projections of the protruding column 115 and the protruding plate 36 are both located within the vertical projection of the clearance notch 31. This design helps to improve the utilization rate of the internal space of the shell 1 and enhances the compactness of the structure.

[0157] For example, a buffer 5 can be provided between the protruding post 115 and the protruding plate 36. The material of the buffer 5 includes, but is not limited to, elastic materials such as rubber or silicone. With this design, the elastic deformation of the buffer 5 is used to buffer the transmission of vibration of the fan module 4 to the housing 1 through the air duct 3, thereby improving the noise reduction effect.

[0158] For example, the protruding plate 36 has a mounting hole 361 extending through the protruding plate 36 along a first direction F1. The buffer 5 is interference-fitted into the mounting hole 361. The protruding post 115 passes through the central hole of the buffer 5. The cleaning device 100 may also include a screw 6. The screw 6 is threaded from one side (the side near the top plate 12) to the end of the protruding post 115 (the end near the top plate 12), and its screw head abuts against the axial end face (the end face facing the top plate 12) of the buffer 5. When the screw 6 is tightened, the buffer 5 is pressed by the screw head, and the elastic deformation of the buffer 5 is used to achieve flexible connection and locking, while effectively attenuating vibration transmission.

[0159] It is worth noting that this explanation uses the example of the protrusion 115 being located on the base plate 11. In other examples, the protrusion 115 can also be located on the inner surface of the top plate 12, or the protrusion 115 can be located on both the inner surface of the top plate 12 and the inner surface of the base plate 11. When the protrusion 115 is located on the top plate 12, the screw 6 corresponding to the protrusion 115 on the top plate 12 is threaded to the end of the protrusion 115 near the base plate 11 from the side near the base plate 11, and the screw head abuts against the end face of the buffer 5 facing the base plate 11.

[0160] To securely fix the buffer 5 and prevent it from falling off or rotating, a raised rib 362 can be provided on the inner circumferential surface of the mounting hole 361. The raised rib 362 extends circumferentially along the mounting hole 361, and a corresponding groove 51 is machined on the outer circumferential surface of the buffer 5. During installation, the raised rib 362 is inserted into the groove 51 to achieve circumferential and axial positioning.

[0161] The rib 362 can be integrally connected to the rib plate 36, or it can be connected by means of adhesive, welding, snap-fit ​​or screw connection.

[0162] For example, one circumferential end of the mounting hole 361 may be designed with a deformable opening 363, which facilitates the press-in installation of the buffer 5.

[0163] For example, please continue reading Figure 11 A third reinforcing rib 364 is provided on at least one side surface of the protruding plate 36 in the thickness direction (i.e., the first direction F1). The third reinforcing rib 364 can be connected to the inner circumferential surface of the clearance notch 31, thereby enhancing the rigidity of the protruding plate 36.

[0164] For example, along the protruding direction of the protrusion plate 36 (away from the direction of the air duct 3), the cross-sectional area of ​​the protrusion plate 36 can be designed to gradually decrease, so as to reduce weight and facilitate demolding while ensuring connection strength.

[0165] The internal structure of air duct component 3 will be explained in detail below.

[0166] Please see Figure 12 , Figure 12 This is an exploded view of the air duct component 3 provided in some other embodiments of this application. The difference between this air duct component 3 and the air duct component 3 in the above embodiments is that the air duct component 3 has multiple noise-reducing ribs 37 arranged inside. Specifically, multiple noise-reducing ribs 37 are arranged in the main airflow channel area between the air inlet 33 and the air outlet 32 ​​inside the air duct component 3. These noise-reducing ribs 37 can be arranged at intervals. By setting multiple noise-reducing ribs 37, the flow path of the fluid in the air duct component 3 can be extended, and the noise-reducing ribs 37 can also be used to disturb, divide and reorganize the passing airflow, disperse large-scale vortices, promote uniform flow velocity, and thus reduce airflow noise.

[0167] There are two exhaust vents 32, and the air inlet 33 is located between the two exhaust vents 32. Multiple noise-reducing ribs 37 are provided in the area between each exhaust vent 32 and air inlet 33 within the air duct component 3. The following explanation uses the multiple noise-reducing ribs 37 located between one of the exhaust vents 32 and air inlet 33 as an example.

[0168] The arrangement of the noise-reducing ribs 37 can be varied. In some embodiments, please refer to [link / reference needed]. Figure 12The aforementioned noise-reducing ribs 37 may include a first group of noise-reducing ribs 37a and a second group of noise-reducing ribs 37b distributed along the width direction (second direction F2) of the air duct component 3. The first group of noise-reducing ribs 37a includes multiple first noise-reducing ribs 371. The multiple first noise-reducing ribs 371 are spaced apart along the length direction (third direction F3) of the air duct component 3. The second group of noise-reducing ribs 37b includes multiple second noise-reducing ribs 372. The multiple second noise-reducing ribs 372 are also spaced apart along the length direction of the air duct component 3. This design is beneficial for making full use of the width dimension of the air duct component 3, allowing multiple noise-reducing ribs 37 to be arranged along both the width and length directions of the air duct component 3, further extending the flow path of the fluid within the air duct component 3, and further utilizing the noise-reducing ribs 37 to disturb, divide, and reorganize the passing airflow, breaking up large-scale vortices, promoting flow velocity uniformity, and thus reducing airflow noise.

[0169] For example, viewed along the length of the air duct component 3, multiple first noise-reducing ribs 371 and multiple second noise-reducing ribs 372 are arranged alternately. Furthermore, a portion of one first noise-reducing rib 371 may be directly opposite a portion of an adjacent second noise-reducing rib 372 along the length of the air duct component 3. This staggered arrangement causes continuous and alternating disturbances to the airflow during its flow, resulting in better noise reduction.

[0170] For example, multiple first noise-reducing ribs 371 in the same group can be parallel to each other. This design makes it easier to process and manufacture the air duct component 3.

[0171] For example, multiple second noise-reducing ribs 372 in the same group can be parallel to each other. This design makes it easier to process and manufacture the air duct component 3.

[0172] For example, the first noise-reducing rib 371 and the second noise-reducing rib 372 can be parallel to each other. This design facilitates the processing and manufacturing of the air duct component 3.

[0173] The extension direction of the noise-reducing rib 37 can be flexibly designed. For examples, please refer to [link / reference needed]. Figure 12 Each noise-reducing rib 37 can be inclined relative to the length of the air duct component 3. This can more effectively guide and divide the airflow.

[0174] For example, the inclination angle β of each noise-reducing rib 37 relative to the length direction of the air duct component 3 is greater than or equal to 45° and less than 90°. For instance, the inclination angle β of the noise-reducing rib 37 relative to the length direction of the air duct component 3 is 60°, 65°, 66°, 68°, 70°, 72°, 75°, 78°, 80°, 82°, 85°, or 88°.

[0175] Of course, this application is not limited to this. In other examples, each noise reduction rib 37 may be set perpendicular to the length direction of the air duct component 3.

[0176] The shape of the noise reduction rib 37 can be straight, curved, or broken to adapt to different flow field optimization requirements.

[0177] For example, to balance noise reduction and fluid resistance reduction, please refer to... Figure 13 , Figure 13 According to Figure 12 The diagram shows an enlarged view of the portion circled at H in the air duct component 3. Multiple vents 373 can be formed through each noise-reducing rib 37. These vents 373 allow partial airflow penetration, reducing the overall obstruction of airflow by the noise-reducing rib 37 and lowering pressure loss while providing moderate disturbance.

[0178] It is understandable that air holes 373 can also be made on some of the noise reduction ribs 37. For example, air holes 373 can be made on one, two, three, four or five noise reduction ribs 37 closest to the air outlet 112, as long as at least one noise reduction rib 37 has an air hole 373 that penetrates through the noise reduction rib 37.

[0179] For example, to enhance turbulent mixing, please refer to Figure 14 , Figure 14 This is a partially enlarged view of the internal structure of the air duct component 3 in some embodiments of this application. Multiple turbulence protrusions 374 are provided on the side of each noise-reducing rib 37 facing the upstream airflow. The turbulence protrusions 374 are spaced apart along the length of the noise-reducing rib 37.

[0180] It is understandable that turbulence protrusions 374 can also be provided on some of the noise reduction ribs 37. For example, turbulence protrusions 374 can be provided on one, two, three, four or five noise reduction ribs 37 closest to the air inlet 33, as long as at least one noise reduction rib 37 has a turbulence protrusion 374.

[0181] For example, the upstream side of the turbulence protrusion 374 can be a curved surface, such as an arc or an elliptical arc, which can further refine the airflow and reduce wind resistance.

[0182] The structure of track 23 will be explained in detail below.

[0183] To make the airflow from the exhaust vent 32 more effective at acting on the track 23 and the surface to be cleaned, the track 23 itself can be modified. (See also...) Figure 15 , Figure 15This is an assembly diagram of the track 23 and drive hub 22 in some other embodiments of this application. The outer peripheral surface of the track 23 has track grooves 231 for increasing friction. The track 23 has airflow holes 232 that penetrate the body of the track 23 along its own thickness direction (i.e., the arrangement direction of the outer peripheral surface and the inner peripheral surface).

[0184] Importantly, the airflow hole 232 is located at the track groove 231. This design not only does not reduce the contact area between the outer circumference of the track 23 and the surface to be cleaned, but also ensures that when the high-speed airflow from the exhaust port 32 acts on the track 23, a portion of the airflow passes through the airflow hole 232 on the track section near the exhaust port 32 and acts on the track section in contact with the surface to be cleaned. This "penetrating" effect reduces intermediate links in force transmission, more directly enhancing the local pressure in the contact area, improving the anti-slip effect, and simultaneously enhancing the ability to remove stubborn dirt from the track groove 231.

[0185] The shape of the airflow hole 232 includes, but is not limited to, a circular hole, a rectangular hole, a triangular hole, or an irregularly shaped hole.

[0186] The design parameters of the airflow orifice 232 need to balance the effect with the strength of the track 23. For example, the equivalent diameter of the airflow orifice 232 (for non-circular orifices, the diameter of a circle with equal area) ranges from 1 mm to 2 mm. This size ensures sufficient airflow without excessively weakening the track 23 structure.

[0187] For example, the equivalent diameter of the airflow hole 232 can be 1.5 mm, 1.8 mm or 1.9 mm.

[0188] The number of airflow holes 232 can be multiple. These multiple airflow holes 232 are spaced apart along the circumference of the track 23. Different airflow holes 232 can be located within different track grooves 231. This design helps to improve the uniformity of the structural strength of the track 23 in its circumferential direction.

[0189] For example, the total opening area of ​​all airflow holes 232 should be less than 10% of the total area of ​​the outer peripheral surface of the track 23. This design ensures sufficient airflow without excessively weakening the structure of the track 23.

[0190] It can be understood that the area of ​​the outer periphery of track 23 refers to the length of the rectangular plate when track 23 is cut open and unfolded into a flat rectangular plate. The value obtained from the width calculation. The total opening area of ​​the airflow holes 232 refers to the sum of the opening areas of all the airflow holes 232 on the outer circumferential surface of the track 23.

[0191] For example, please continue reading Figure 15The airflow hole 232 is located in the middle region of the track 23 in the width direction. This region is the core area of ​​contact between the track 23 and the surface to be cleaned, and its structural strength is relatively high. The placement of the airflow hole 232 in this position ensures both the structural strength of the track 23 and the ability of the airflow passing through the airflow hole 232 to act on this core region, thereby increasing the local pressure between the track 23 and the surface to be cleaned at this core location. After the airflow acts on this central region, it can flow to both sides along the width direction of the track 23, which helps to improve the uniformity and symmetry of the force on the track 23, thus improving the anti-slip effect. It also facilitates the airflow acting on the track 23 to be discharged from the air outlet 112 along both sides of the width direction of the track 23, while enhancing the ability to remove stubborn dirt from the track groove 231.

[0192] For example, from the perspective of airflow utilization efficiency, the airflow hole 232 can be designed as a tapered hole. That is, the cross-sectional area of ​​the airflow hole 232 gradually decreases from the outer peripheral surface to the inner peripheral surface of the track 23. This structure can generate a certain pressure boosting effect when the airflow passes through, making the airflow pressure acting on the track 23 section in contact with the surface to be cleaned higher, further increasing the clamping force between the track 23 and the surface to be cleaned.

[0193] For example, the track 23 includes a first segment 2321 and a second segment 2322 arranged in parallel. It is understood that during the movement of the cleaning device 100, the track 23 rotates with the rotation of the drive hub 22. Therefore, the first segment 2321 and the second segment 2322 do not specifically refer to a certain segment on the track 23. Regardless of how the track 23 rotates, the track segment on the side of the track 23 away from the surface to be cleaned (that is, the track segment 23 on the side of the drive hub 22 away from the surface to be cleaned) is always called the first segment 2321, and the track segment in contact with the surface to be cleaned (that is, the track segment between the drive hub 22 and the surface to be cleaned) is called the second segment 2322. As the track 23 rotates, the first segment 2321 and the second segment 2322 are defined by different parts of the track 23 in the circumferential direction.

[0194] The airflow holes 232 on the first segment 2321 are spaced apart from the airflow holes 232 on the second segment 2322 by their vertical projection. This staggered hole layout avoids the airflow holes 232 from the first segment 2321 directly acting on the airflow holes 232 on the second segment 2322, allowing the airflow holes 232 from the first segment 2321 to act more effectively on the solid surface of the second segment 2322, thereby increasing the airflow pressure acting on the second segment 2322 and further improving the clamping force between the track 23 and the surface to be cleaned.

[0195] It is understandable that during the rotation of track 23, airflow holes 232 may not always be present on the first segment 2321, and similarly, airflow holes 232 may not always be present on the second segment 2322. When track 23 rotates to a specific position, and the vertical projection of the airflow holes 232 on the first segment 2321 falls within the range of the second segment 2322, the vertical projection of the airflow holes 232 on the first segment 2321 and the airflow holes 232 on the second segment 2322 need to be spaced apart.

This application also provides a cleaning equipment assembly 1000. The cleaning equipment assembly 1000 includes: a base station 200 and the aforementioned cleaning equipment 100.

[0197] The base station 200 can serve to house the cleaning equipment 100, so as to enable functions such as cleaning and / or charging of the cleaning equipment 100.

[0198] Base station 200 has a receiving cavity (not shown). Cleaning device 100 has a usage state and a storage state. In the storage state, cleaning device 100 is located inside the receiving cavity. In the usage state, cleaning device 100 is located outside base station 200 to facilitate cleaning of the surface to be cleaned.
