Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning mechanism and cleaning device. Background Technology

[0002] Robotic vacuum cleaners, mops, and floor scrubbers are types of smart home appliances that use artificial intelligence to automatically clean floors in a room. The cleaning components (such as the center brush and side brushes at the bottom of a robotic vacuum cleaner) sweep debris into the cleaning unit. After the sweeping components have finished, the cleaning unit uses a mop to wet-clean the floor, removing dust, stains, and dirt that the sweeping components couldn't reach, thus improving the overall cleaning effect.

[0003] During the wet cleaning process, the cleaning device continuously sprays clean water from its water tank onto the mop to clean it. The wastewater generated after cleaning needs to be collected. To address this, the cleaning device includes a scraper that adheres to the mop. As the mop rotates, the scraper removes wastewater and debris, guiding it through an inlet into the device's collection box. However, in actual use, the flexible scraper may not adhere tightly to the mop, resulting in poor scraping and affecting the mop's self-cleaning effect. Utility Model Content

[0004] The main objective of this application is to provide a cleaning mechanism and cleaning device to solve the problem mentioned in the background art of poor scraping effect of scrapers on mops.

[0005] According to one aspect of this application, a cleaning facility is provided, comprising:

[0006] A cleaning assembly, comprising a support and a flexible cleaning component, the flexible cleaning component being mounted on the support and rotatable relative to the support;

[0007] A wiper assembly, comprising a wiper body and an interference member, wherein the wiper body is connected to the bracket, the interference member is disposed on the wiper body and abuts against the flexible cleaning component, and the interference member is a structural component made of a material with a hardness greater than that of the wiper body.

[0008] Furthermore, the wiper body includes a first side and a second side disposed opposite to each other. The first side is located on the side of the wiper body closer to the flexible cleaning component, and the second side is located on the side of the wiper body away from the first side. The wiper body is provided with a drainage structure that guides wastewater from the first side to the second side. The interference member includes a metal plate disposed on the first side.

[0009] Furthermore, the flexible cleaning component includes a roller and a mop, the roller being rotatably connected to the bracket, the mop wrapping around the outer periphery of the roller, the squeegee body and the metal plate both extending along the axial direction of the roller, and the metal plate being interference-fitted with the mop.

[0010] Furthermore, the wiper body is provided with a mounting groove, the mounting groove is located on the first side, and the metal plate is embedded in the mounting groove and at least partially located outside the mounting groove.

[0011] Alternatively, the mounting groove may be located near the outer wall of the roller and be interference-fitted with the mop.

[0012] Further, the metal plate includes:

[0013] A fixing section is disposed within the mounting groove;

[0014] The wiping section is located on the side of the fixed section away from the bottom of the mounting groove and protrudes out of the mounting groove. Along the first direction, the wiping section bends upward in a direction away from the flexible cleaning component.

[0015] Furthermore, the wiper body is also provided with a sludge collection tank, which is located on the first side and on the side of the metal plate away from the flexible cleaning component. The drainage structure includes:

[0016] A drainage channel, the drainage channel being located on the second side;

[0017] A drain outlet, along the second direction, is located on the side of the drain channel away from the support and is connected to the drain channel;

[0018] The filter holes, along the second direction, are disposed through the side wall of the drainage trough near the support and communicate with the sludge collection trough. The filter holes include a plurality of holes, which are arranged along the axial direction of the roller.

[0019] Furthermore, a cavity is provided on the side of the sludge collection tank near the metal plate. The cavity is recessed into the inner wall of the sludge collection tank, and the length of the cavity extends along the axial direction of the roller.

[0020] Furthermore, along the axial direction of the roller, the projected outer contour of the cavity is arc-shaped.

[0021] Furthermore, along the axial direction of the roller, the projected outer contour of the portion of the metal plate outside the mounting groove protrudes beyond the projected outer contour of the sludge collection trough.

[0022] Furthermore, the wiper assembly also includes a cover, which is connected to the bracket. A snap-fit ​​structure is provided between the cover and the second side, and the wiper body and the cover are detachably connected through the snap-fit ​​structure.

[0023] On the other hand, this application also provides a cleaning device, which includes the cleaning mechanism described above.

[0024] In this application, by incorporating an interference element on the wiper body, and ensuring that the material hardness of the interference element is greater than that of the wiper body, the interference element allows for a tighter contact with the flexible cleaning component. The interference element is less prone to deformation, improving the flatness of the contact side between the wiper assembly and the flexible cleaning component. This prevents any unwiped areas on the flexible cleaning component and reduces the likelihood of debris getting stuck between the interference element and the flexible cleaning component, thus more effectively removing wastewater and debris from the flexible cleaning component and enhancing its cleaning performance, ensuring better self-cleaning capabilities.

Detailed Implementation

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] The metal plates used for scraping dirt off roller mops are usually injection molded parts. After injection molding, due to stress and other environmental factors during use (such as collision deformation), the parts where the metal plate contacts the roller mop may be uneven. For example, the parts where the metal plate contacts the roller mop may have local bulges and / or depressions. The bulges may scratch the mop, while the depressions may not be able to scrape the mop, leaving dirty water and dirt inside the mop and reducing the cleanliness of the mop.

[0039] like Figures 1 to 7As shown, to address the aforementioned problems, this embodiment provides a cleaning mechanism. This cleaning mechanism includes a cleaning component and a squeegee component. The cleaning component includes a support 10 and a flexible cleaning part 20. The flexible cleaning part 20 is mounted on the support 10 and can rotate relative to the support 10. The squeegee component includes a squeegee body 30 and an interference member 40. The squeegee body 30 is connected to the support 10. The interference member 40 is disposed on the squeegee body 30 and abuts against the flexible cleaning part 20. The interference member 40 is a structural component whose material hardness is greater than that of the squeegee body 30. Due to its higher hardness, the interference member 40 is less prone to deformation and compensates for uneven areas on the squeegee body 30, thereby scraping away sewage and debris from the flexible cleaning part 20, preventing any unscraped areas from being scraped, and improving the cleanliness of the flexible cleaning part 20.

[0040] In this embodiment, by providing an interference member 40 on the wiper body 30, and the material hardness of the interference member 40 being greater than that of the wiper body 30, the interference member 40 can more tightly abut against the flexible cleaning component 20. The interference member 40 is not easily deformed, and it can improve the flatness of the side of the wiper assembly that abuts against the flexible cleaning component 20, avoiding any un-wiped areas on the flexible cleaning component 20. Furthermore, it prevents debris from easily getting stuck between the interference member 40 and the flexible cleaning component 20, thus more effectively removing wastewater and debris from the flexible cleaning component 20, improving the wiping effect on the flexible cleaning component 20, and ensuring that the flexible cleaning component 20 has a better self-cleaning effect.

[0041] In this embodiment, when the wiper body 30 is an injection-molded part, in one embodiment, the wiper body 30 includes a first side 31 and a second side 32 disposed opposite to each other. The first side 31 is located on the side of the wiper body 30 closer to the flexible cleaning component 20. The second side 32 is located on the side of the wiper body 30 away from the first side 31. The wiper body 30 is provided with a drainage structure 33. The drainage structure 33 guides the wastewater from the first side 31 to the second side 32. The interference member 40 includes a metal plate disposed on the first side 31. The metal plate has high material hardness, as well as high wear resistance and deformation resistance. The metal plate can tightly abut against the flexible cleaning component 20 to scrape off the wastewater and debris on the flexible cleaning component 20, ensuring that the flexible cleaning component 20 has a better self-cleaning effect. Even after the wiper assembly has been used for a long time, the metal plate can still tightly abut against the flexible cleaning component 20, and the metal plate can maintain stable scraping performance during long-term use, ensuring that the metal plate achieves a good scraping effect on the flexible cleaning component 20. The drainage structure 33 efficiently guides the wastewater scraped off by the interference member 40 to the second side 32, ensuring that the wastewater can be discharged quickly and smoothly. This effectively prevents wastewater from accumulating in the scraper body 30 and flowing back onto the flexible cleaning member 20, thus improving the self-cleaning effect of the flexible cleaning member 20. The combination of the rigid scraping ability of the metal plate and the efficient guiding effect of the drainage structure 33 significantly improves the self-cleaning effect of the flexible cleaning member 20, reduces dirt residue, and enhances the cleaning performance of the cleaning mechanism.

[0042] like Figures 1 to 3 As shown, to ensure good scraping performance of the metal plate, in one embodiment, the flexible cleaning component 20 includes a roller 21 and a mop 22. The roller 21 is rotatably connected to the bracket 10. The mop 22 wraps around the outer periphery of the roller 21. The squeegee body 30 and the metal plate both extend along the axial direction of the roller 21, and the metal plate and the mop 22 are interference-fitted. The interference-fit connection between the metal plate and the mop 22 ensures that the metal plate can closely adhere to the surface of the mop 22, effectively preventing the problem of incomplete scraping caused by the material being too soft or deformed, or by unevenness caused by the injection molding process, which is a problem with traditional flexible squeegees. This significantly improves the scraping performance of the squeegee assembly. The wiping body 30 and the metal plate extend along the axial direction of the roller 21, ensuring that the wiping body 30 and the metal plate have a large working area, reducing cleaning dead corners, and ensuring that the wiping body 30 and the metal plate can effectively scrape away sewage and garbage from all areas of the mop 22 surface, improving the scraping effect of the wiping component, significantly improving the self-cleaning effect of the mop 22, and reducing dirt residue on the mop 22.

[0043] The squeegee body 30 has a mounting groove 34 located on the first side 31. In one embodiment, a metal plate is embedded in the mounting groove 34 and at least partially outside it. The mounting groove 34 provides precise positioning and a stable limiting function for the metal plate, preventing it from shifting or falling off during long-term contact with the mop 22 and during vibrations generated during operation. This ensures the stability and continuity of the squeegee work and guarantees the stable operation of the cleaning mechanism. The mounting groove 34 also provides some support for the metal plate, making the force on the metal plate more even during squeegeeing and ensuring its stability. The fact that the metal plate is at least partially outside the mounting groove 34 increases the contact area and squeegee pressure between the metal plate and the mop 22, allowing the metal plate to exert greater force on the mop 22, effectively removing wastewater and debris from the mop 22 and improving the squeegee effect.

[0044] In another embodiment, the mounting groove 34 is interference-fitted with the outer wall of the roller 21 near the mop 22. This interference fit increases the contact area between the squeegee assembly and the mop 22. When the squeegee assembly is working, the larger contact area allows for more thorough removal of wastewater and debris from the mop 22, improving its cleaning effect and ensuring a more thorough cleaning of the mop 22, thus enhancing the overall cleanliness of the floor. Furthermore, this arrangement allows for more even force distribution on the mop 22 in the circumferential direction, effectively preventing wear or uneven cleaning performance caused by uneven local force distribution. This ensures consistent cleaning performance across all parts of the mop 22 during one rotation of the roller 21, improving the self-cleaning effect of the mop 22. It is understood that the above embodiments can be implemented individually or in combination.

[0045] like Figure 4 As shown, the metal plate includes a fixing section 41 and a wiping section 42. The fixing section 41 is disposed within the mounting groove 34. The fixing section 41 can be securely installed within the mounting groove 34, ensuring the metal plate is firmly installed on the wiping body 30, preventing the metal plate from loosening due to vibration or other factors during the operation of the cleaning mechanism, and ensuring that the wiping assembly can work more stably. The wiping section 42 is located on the side of the fixing section 41 opposite to the bottom of the mounting groove 34 and protrudes out of the mounting groove 34. Along the first direction (e.g. Figure 2The direction indicated by the middle arrow X (specifically, the height direction of the roller 21) is such that the squeegee section 42 bends upwards away from the flexible cleaning component 20. The squeegee section 42 protrudes from the mounting groove 34 and can directly contact the mop cloth 22, effectively removing sewage and debris from the mop cloth 22. The angle formed by the upward bending of the squeegee section 42 and the fixed section 41 allows sewage to enter the drainage structure 33 along the squeegee section 42, effectively preventing sewage from splashing, flowing to the ground, or flowing back onto the mop cloth 22. The squeegee section 42 forms an angle that matches the rotation direction of the mop cloth 22. When the mop cloth 22 rotates, the bent squeegee section 42 can scrape the surface of the mop cloth 22 at a closer angle, reducing scraping resistance and improving the efficiency of removing sewage and debris. The bending angle prevents the edge of the squeegee section 42 from directly scraping perpendicularly against the mop cloth 22, reducing cutting damage to the fibers of the mop cloth 22 and thus extending the service life of the mop cloth 22. The squeegee section 42 can more efficiently scrape sewage and debris off the mop 22, improving its cleaning performance. Furthermore, the bent squeegee section 42 has higher structural strength. During frequent contact with the mop 22, the bent squeegee section 42 is less prone to deformation under stress, ensuring that it maintains good cleaning performance and consistently cleans the mop 22.

[0046] like Figures 5 to 7 As shown, to prevent wastewater from accumulating and flowing back onto the mop 22, in one embodiment, the squeegee body 30 is also provided with a sludge collection trough 37. The sludge collection trough 37 is located on the first side 31 and on the side of the metal plate away from the flexible cleaning component 20. The drainage structure 33 includes a drainage channel 331, a drainage outlet 332, and a filter hole 333. The drainage channel 331 is located on the second side 32. Along the second direction (e.g. Figure 2 The direction indicated by the middle arrow Y (the second direction is perpendicular to the first direction) is where the drain outlet 332 is located on the side of the drain trough 331 away from the support 10 and is connected to the drain trough 331. Along the second direction, filter holes 333 are provided through the side wall of the drain trough 331 near the support 10 and are connected to the sludge collection trough 37. Multiple filter holes 333 are arranged along the axial direction of the roller 21. Wastewater and debris scraped off by the metal plate enter the sludge collection trough 37. The wastewater enters the drain trough 331 through the filter holes 333 and is finally discharged through the drain outlet 332. Debris is intercepted by the filter holes 333, effectively preventing debris from clogging the drain outlet 332, thus ensuring that wastewater does not accumulate in the squeegee body 30 and cause secondary pollution to the mop 22. Multiple filter screens increase the filtration surface of the filter holes 333, accelerating the filtration efficiency of wastewater and debris, ensuring that wastewater can be discharged more quickly, and preventing wastewater from flowing back onto the mop 22. Multiple filter holes 333 are arranged along the axial direction of the roller 21, and the sewage scraped out by the mop 22 at various positions along the axial direction can flow into the drain trough 331 more quickly through the filter holes 333 and be discharged more effectively, thus improving the sewage discharge speed.

[0047] The sludge collection trough 37 has a recess 371 on the side near the metal plate. The recess 371 is recessed into the inner wall of the sludge collection trough 37, and its length extends along the axial direction of the roller 21. Debris intercepted by the filter holes 333 can be temporarily stored in the recess 371, preventing it from getting stuck between the metal plate and the mop 22 and affecting the scraping effect of the metal plate. Because the recess 371 extends along the axial direction of the roller 21, during the rotation of the roller 21, the debris scraped off by the metal plate can fall more smoothly and quickly into the recess 371, more effectively preventing debris from getting stuck between the metal plate and the mop 22, thereby improving the scraping effect of the metal plate and the self-cleaning effect of the mop 22. Furthermore, users can more easily clean the debris collected in the recess 371, improving user convenience.

[0048] Along the axial direction of the roller 21, the projected outer contour of the cavity 371 is arc-shaped. This arc-shaped cavity 371 has a larger storage capacity, allowing it to temporarily hold more debris, thus improving the debris collection ability of the wiper body 30 and enhancing the cleaning efficiency of the cleaning mechanism. Debris also slides more easily along the inner wall of the cavity 371 and accumulates within it, reducing the likelihood of debris accumulating at the edge of the collection trough 37 and effectively preventing debris from getting stuck between the metal plate and the mop 22, thus affecting the scraping effect of the metal plate.

[0049] Along the axial direction of the roller 21, the projected outer contour of the portion of the metal plate outside the mounting groove 34 protrudes beyond the projected outer contour of the sludge collection trough 37. This arrangement allows for a wider contact area between the metal plate and the mop 22, enabling the metal plate to cover the area of ​​the mop 22 near the edge of the sludge collection trough 37. This allows for more thorough scraping of wastewater and debris from the mop 22, improving its self-cleaning effect. During the scraping process, the protruding portion of the metal plate can more precisely guide the scraped wastewater and debris into the sludge collection trough 37. When the metal plate scrapes across the mop 22, the wastewater and debris fall directly into the sludge collection trough 37 along the protruding portion of the metal plate, reducing splashing or scattering of wastewater and debris outside the trough 37, improving wastewater and debris collection efficiency, and enhancing the self-cleaning effect of the mop 22.

[0050] To facilitate cleaning the debris in the cavity 371, in one embodiment, the wiper assembly also includes a cover 50. The cover 50 is connected to the bracket 10, and a snap-fit ​​structure is provided between the cover 50 and the second side 32 of the wiper body 30, allowing the wiper body 30 and cover 50 to be detachably connected via the snap-fit ​​structure. By unlocking the snap-fit ​​structure, the wiper body 30 can be removed from the bracket 10. This design makes it easier for the user to remove the wiper body 30 and clean the debris in the cavity 371. Furthermore, the detachable structure of the wiper body 30 facilitates replacement and maintenance of the wiper body 30 without replacing the entire cleaning mechanism, reducing the maintenance cost of the cleaning mechanism.

[0051] The latching structure includes a locking tongue 51 and a through hole 52. In one embodiment, the locking tongue 51 is disposed on the wiper body 30, and the locking tongue 51 is provided with a slot. The through hole 52 passes through the cover 50, and a boss is provided on the inner wall surface of the through hole 52. After the locking tongue 51 extends into the through hole 52, the boss is embedded in the slot to achieve a latching connection, thereby fixing the wiper body 30 to the cover 50. When disassembling the wiper body 30, the user presses the locking tongue 51 to separate the slot from the boss, thereby removing the wiper body 30 from the cover 50.

[0052] On the other hand, this application also provides a cleaning device that includes the aforementioned cleaning mechanism. This cleaning device incorporates all the technical effects of the aforementioned cleaning mechanism. Since the technical effects of the cleaning mechanism have already been described in detail above, they will not be repeated here.

[0053] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0054] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
