Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a cleaning module and cleaning equipment. Background Technology

[0002] Cleaning modules typically utilize cleaning components such as cloth trays, roller brushes, and conveyor belts to clean surfaces. To enhance cleaning effectiveness, cleaning modules usually include a washing mechanism that sprays water or cleaning fluid onto the cleaning components to moisten them and improve their ability to remove dirt.

[0003] In existing technologies, the cleaning mechanism is typically attached to the housing of the cleaning component using screws. The problem with this mounting structure is that after repeated disassembly and reassembly, the screw threads are prone to stripping, especially on plastic housings, resulting in insufficient connection reliability. Furthermore, to ensure connection strength, certain requirements are placed on the axial dimension of the threads, leading to a larger installation space and a less compact cleaning module structure. Additionally, the screw connection and disassembly process is cumbersome, making maintenance of the cleaning mechanism inconvenient. Utility Model Content

[0047] Please see Figures 1 to 13 This utility model provides a cleaning module 200 and a cleaning device including the same. In this utility model, the cleaning device is an electric cleaning tool that can use the cleaning module 200 to clean a surface to be cleaned. It can be a mobile cleaning device, such as a robot vacuum cleaner, or a handheld cleaning device, such as a floor scrubber. Specifically, during movement, the cleaning device uses the cleaning components 20 in the cleaning module 200 to clean the surface to be cleaned, removing dirt and grime.

[0048] like Figure 1 and Figure 2 As shown, the cleaning module 200 mainly includes a housing assembly 100 and a cleaning component 20. Generally, the cleaning module 200 also includes a drive assembly for driving the cleaning component 20. The cleaning component 20 is movably mounted on the housing assembly 100 and is driven by the drive assembly to achieve active cleaning of the surface to be cleaned. The specific type of the cleaning component 20 and its mode of operation are not limited. For example, it can be a wiping disc driven to rotate or move back and forth by the drive assembly, a roller brush driven to rotate by the drive assembly, or a conveyor belt wiping cloth that rotates around a roller axis during the cleaning process.

[0049] To improve the cleaning effect on the surface to be cleaned, in this embodiment, the housing assembly 100 mainly consists of a housing 10 and a cleaning mechanism 30. The housing 10 forms the main frame for installing and protecting the components of the cleaning module 200, and its material is generally engineering plastic. The cleaning component 20 is movably mounted on the housing 10, and the cleaning mechanism 30 is also detachably mounted on the housing 10 and is used to provide water to the cleaning component 20. When the cleaning module 200 is working, the cleaning mechanism 30 directly sprays or drips water onto the cleaning component 20 and / or the surface to be cleaned, making the surface wet, softening and dissolving the dirt, so that it can be more easily scraped off by the cleaning component 20.

[0050] It is understood that the cleaning mechanism 30 should be connected to a water source via a pipeline. This water source could be a water storage tank for storing clean water and / or cleaning fluid, allowing the cleaning mechanism 30 to directly spray clean water or a cleaning fluid mixed with detergent. The pipeline may be equipped with control valves, mixing devices, etc., to start or stop supplying water to the cleaning mechanism 30 as needed, or to supply clean water or cleaning fluid as needed. Specific details can be found in existing technology, which will not be elaborated upon here.

[0051] In existing technology, the cleaning mechanism 30 is generally attached to the housing 10 by screws. This mounting structure, especially for plastic housings, leads to stripped threads after repeated disassembly and reassembly, resulting in insufficient connection reliability. Furthermore, to ensure connection strength, certain requirements are placed on the axial dimension of the threads, and the installation occupies a significant amount of space. To solve these problems, please refer to [further details needed]. Figures 3 to 6 In this embodiment, the housing 10 is provided with a first mounting structure 11, the cleaning mechanism 30 is provided with a second mounting structure 31, and the cleaning module 200 also includes a snap-fit ​​member 40. One of the first mounting structure 11 and the second mounting structure 31 includes a first mounting hole 111, and the other includes a locking member 311. The locking member 311 is inserted into the first mounting hole 111 and engages with the snap-fit ​​member 40 to limit the movement of the cleaning mechanism 30 relative to the housing 10.

[0052] Specifically, such as Figure 4 and Figure 6 One embodiment may have a first mounting hole 111 on the housing 10, and a locking member 311 on the cleaning mechanism 30 may be inserted into the first mounting hole 111 and engaged between the housing 10 and the locking member 311 by a snap-fit ​​member 40, thereby restricting the movement of the locking member 311 relative to the first mounting hole 111 in the axial, circumferential, and radial directions, thus connecting and fastening the cleaning mechanism 30 and the housing 10. In another embodiment (not shown in the figure), the locking member 311 may be provided on the housing 10, and the first mounting hole 111 may be provided on the cleaning mechanism 30, which may be engaged between the housing 10 and the locking member 311 by a snap-fit ​​member 40, thereby restricting the movement of the locking member 311 relative to the first mounting hole 111 in the axial, circumferential, and radial directions, thus connecting and fastening the cleaning mechanism 30 and the housing 10.

[0053] In this embodiment, the cleaning mechanism 30 and the housing 10 are detachably connected by a snap-fit ​​mechanism using the locking member 311, the first mounting hole 111, and the snap-fit ​​member 40. Compared to threaded fastening, this snap-fit ​​structure does not rely on thread engagement, and even after repeated disassembly and assembly of the cleaning mechanism 30, stripping will not occur, ensuring greater connection reliability and facilitating disassembly and assembly, thus improving the assembly efficiency and structural strength of the cleaning module 200. Simultaneously, the size of the snap-fit ​​member 40 can be made smaller due to the rubber thread structure, resulting in a smaller installation space and a more compact overall structure for the cleaning module 200, making it particularly suitable for size-sensitive devices such as robotic vacuum cleaners. Furthermore, the snap-fit ​​member 40 allows for quick disassembly and assembly, improving the assembly and maintenance efficiency of the cleaning module 200.

[0054] Based on the above embodiments, the location and number of connection points between the first mounting structure 11 and the second mounting structure 31 can be designed as needed. For example, connection points can be set only at both ends of the cleaning mechanism 30, or the number of connection points can be adjusted according to the length of the cleaning mechanism 30. In an optional embodiment, the cleaning component 20 is rotatably mounted on the housing 10 about an axially extending shaft. Multiple first mounting holes 111 and locking components 311 are respectively provided. At least a portion of the first mounting holes 111 are spaced apart axially, and at least a portion of the locking components 311 are spaced apart axially and are inserted into the multiple first mounting holes 111 in a one-to-one correspondence. In this embodiment, the weight and working load of the cleaning mechanism 30 are evenly distributed through the multiple axially distributed connection points, reducing local deformation of the housing 10. This is particularly suitable for the high-speed rotating cleaning component 20, reducing vibration noise and extending the service life of the cleaning module 200.

[0055] Based on the previous embodiment, please refer to Figures 3 to 7 The housing 10 has a first side 13 facing the cleaning component 20 and a second side 14 facing away from the cleaning component 20. It is understood that the housing 10 is generally a plate-like structure. Depending on the specific type and installation method of the cleaning component 20, the housing 10 can be configured with different shapes and sizes, and correspondingly, the relative orientations of the first side 13 and the second side 14 will also differ. For example, in an optional embodiment, the housing 10 can be a flat plate structure, and the cleaning component 20 can be a mop tray mounted on the first side 13 of the housing 10, with the second side 14 being the side of the housing 10 facing away from the mop tray. In this embodiment, as... Figure 3 and Figure 5 As shown, the housing 10 can also be constructed as a cylindrical structure with a mounting cavity 12, the mounting cavity 12 having an opening in the circumferential direction, and the cleaning component 20 can be a roller brush rotatably mounted in the mounting cavity 12. In this case, the inner wall of the mounting cavity 12 constitutes the first side 13, and the second side 14 is the outer peripheral wall surrounding the inner wall.

[0056] Please continue to refer to the following: Figures 4 to 7 The first mounting structure 11 includes at least one first mounting hole 111, and each first mounting hole passes through the first side 13 and the second side 14 of the housing 10. The second mounting structure 31 includes a locking member 311 protruding from the outer surface of the cleaning mechanism 30. The locking member 311 passes through the first mounting hole 111, and the end of the locking member 311 extending out of the second side 14 is provided with a boss 3111. The snap-fit ​​member 40 is clamped between the boss 3111 and the second side 14.

[0057] During installation, the locking member 311 of the cleaning mechanism 30 is first inserted into the first mounting hole 111 from the first side 13 of the housing 10, so that the locking member 311 extends from the second side 14. Then, the snap-fit ​​member 40 is fitted onto the outer periphery of the locking member 311 and snaps into the gap between the boss 3111 and the second side 14. The clamping force generated by the elastic deformation of the snap-fit ​​member 40 restricts the axial movement of the cleaning mechanism 30. This structure forms a mechanical limit through the cooperation of the snap-fit ​​member 40, the locking member 311, and the housing 10, achieving reliable fixation without the need for threaded connections. This avoids the problem of stripped threads on the plastic housing 10, and the snap-fit ​​process is simple and quick, effectively improving the efficiency of assembly and subsequent disassembly and maintenance.

[0058] Furthermore, please continue to refer to [the relevant sources]. Figure 4 , Figure 7 and Figures 12 to 15 The locking member 311 has an annular groove 3112 on its outer periphery, located between the second side 14 and the boss 3111. The snap-fit ​​member 40 is sleeved on the outer periphery of the locking member 311 and is at least partially embedded in the annular groove 3112. Thus, the annular groove 3112 restricts the axial movement of the snap-fit ​​member 40 relative to the locking member 311. In a specific implementation, the snap-fit ​​member 40 is made of an elastic material. During installation, external force is used to expand the snap-fit ​​member 40 and fit it into the locking member 311. After the external force is released, the snap-fit ​​member 40 is partially embedded in the annular groove 3112, forming a dual radial and axial limit. In this embodiment, the positioning effect of the annular groove 3112 on the snap-fit ​​member 40 further prevents the snap-fit ​​member 40 from sliding axially along the locking member 311, improving connection stability. Especially under vibration during the operation of the cleaning module 200, the risk of the snap-fit ​​member 40 becoming loose can be reduced.

[0059] Specifically, please refer to the following: Figure 4 and Figure 14 The snap-fit ​​element 40 is a ring-shaped snap ring with a notch 41, preferably a metal spring. For example... Figure 14As shown, the outer diameter D1 of the boss 3111 is smaller than the inner diameter d1 of the first mounting hole 111, the outer diameter D of the annular retaining ring is larger than the inner diameter d1 of the first mounting hole 111, and the inner diameter d of the annular retaining ring is smaller than the outer diameter D1 of the boss 3111. It should be noted that when the locking member 311 or the annular retaining ring is irregularly shaped, the outer diameter D1 of the boss 3111 and the outer diameter D of the annular retaining ring are their maximum dimensions in the direction perpendicular to the axial direction of the locking member 311. The inner diameter d of the annular retaining ring and the inner diameter d1 of the first mounting hole 111 are their minimum dimensions in the direction perpendicular to the axial direction of the locking member 311.

[0060] Thus, by utilizing the dimensional fit of the boss 3111, the annular retaining ring, and the first mounting hole 111, the locking member 311 can be easily extended from the first side 13 to the second side 14 during assembly. After the annular retaining ring is inserted, one side can effectively support the boss 3111, and the other side can support the outer periphery of the first mounting hole 111. The elastic properties of the annular retaining ring material enable quick assembly and disassembly, which can be done by hand without tools. At the same time, the interference fit formed by the dimensional difference ensures that the snap-fit ​​member 40 will not fall off accidentally.

[0061] Based on the above embodiments, the cleaning mechanism 30 may only provide water to the cleaning component 20. In this case, the cleaning mechanism 30 includes a liquid outlet structure 32 but does not include a liquid return structure 33. Alternatively, the cleaning mechanism 30 may simultaneously discharge and recover wastewater. In this case, the cleaning mechanism 30 includes both a liquid outlet structure 32 and a liquid return structure 33.

[0062] Specifically, in an optional embodiment, please refer to Figure 5 , Figure 8 , Figure 9 and Figures 13 to 15 The cleaning mechanism 30 includes a liquid outlet structure 32, in which a liquid outlet cavity 321 is formed and a liquid outlet 322 is provided. Preferably, multiple liquid outlets 322 are provided to spray water more widely and evenly onto the cleaning component 20 or the surface to be cleaned, thereby improving the cleaning effect. The locking member 311 protrudes from the side of the liquid outlet structure 32 facing away from the cleaning component 20, so that the liquid outlet structure 32 can be detachably installed on the housing 10 through the cooperation of the locking member 311, the first mounting hole 111, and the snap-fit ​​member 40. In this embodiment, the liquid outlet cavity 321 is connected to an external water source through a pipeline, and the water is sprayed onto the surface of the cleaning component 20 through the liquid outlet 322. The locking members 311 can be evenly distributed along the length direction of the liquid outlet structure 32 and are respectively snapped and fixed to the housing 10 by multiple snap-fit ​​members 40.

[0063] Optionally, please refer to Figure 5 , Figure 10 , Figures 11 to 15The cleaning mechanism 30 also includes a return liquid structure 33, on which a return liquid channel 3311 is provided. A locking member 311 protrudes from the side of the return liquid structure 33 facing away from the cleaning member 20. In this embodiment, the return liquid channel 3311 is connected to a wastewater tank via a pipeline. Optionally, a suction device providing negative pressure is provided on the pipeline, so that wastewater can be recovered through the return liquid channel 3311, improving cleaning efficiency and effectiveness. The locking members 311 can be evenly distributed along the length of the outlet structure 32 and are respectively locked and fixed to the housing 10 by multiple snap-fit ​​members 40.

[0064] It is understood that the liquid outlet structure 32 and its liquid outlet 322, and the liquid return structure 33 and its liquid return channel 3311 should be adaptively designed according to the installation position and shape and size of the cleaning component 20. Based on the above embodiments, please continue to refer to... Figure 5 and Figures 11 to 16 The cleaning component 20 is rotatably mounted on the housing 10 about a rotating shaft extending axially. The liquid outlet structure 32 and the liquid return structure 33 are arranged sequentially around the circumference of the cleaning component 20 and extend axially, respectively. Preferably, during operation, the cleaning component 20 rotates circumferentially in a first direction about the rotating shaft, while the liquid outlet structure 32 is positioned behind the liquid return structure 33 in the first direction. That is, during the rotation of the cleaning component 20, it first passes through the liquid outlet structure 32 to be wetted, and then the surface to be cleaned is scraped and cleaned under wet conditions, generating wastewater. Subsequently, the cleaning component 20, carrying wastewater, rotates through the liquid return structure 33, where the wastewater is recovered, and then it passes through the liquid outlet structure 32 again to be wetted. This effectively improves cleaning efficiency and cleaning effect.

[0065] In this embodiment, the liquid outlet structure 32 and the liquid return structure 33 can be integrally set or assembled into one piece, and then jointly installed on the housing 10 through the first mounting structure 11, the second mounting structure 31, and the snap-fit ​​member 40. Alternatively, the liquid outlet structure 32 and the liquid return structure 33 can be separately assembled onto the housing 10 through their respective second mounting structures 31, and detachably connected and fixed to the housing 10 to limit their relative positions. Considering that the liquid outlet structure 32 generally has a more complex structure, and that it is more difficult to position the two structures on the housing 10 after assembly, the latter installation method is preferred. In addition, the first side 13 of the housing 10 can also be recessed with a mounting groove to accommodate the liquid outlet structure 32. The mounting groove can achieve pre-positioning of the liquid outlet structure 32 and improve assembly efficiency during assembly. On the other hand, considering that the liquid outlet structure 32 has a liquid outlet cavity 321 formed in it, the thickness of which is generally greater than that of the liquid return structure 33, this arrangement also makes the transition between the liquid outlet structure 32 and the liquid return structure 33 towards the cleaning member 20 smooth, avoiding the formation of a stepped surface between them and the accumulation of dirt.

[0066] Ideally, such as Figure 6As shown, the liquid outlet structure 32 has multiple locking elements 311, which are spaced apart along the axial direction. And / or, the liquid return structure 33 has multiple locking elements 311, which are spaced apart along the axial direction. In practice, the spacing between the locking elements 311 can be adjusted according to load requirements. This design distributes force evenly through multi-point engagement, avoiding excessive load on a single connection point, reducing deformation of the cleaning mechanism 30 due to uneven force distribution, and improving the overall structural stability of the cleaning module 200.

[0067] Furthermore, such as Figures 8 to 11 and Figure 14 As shown, the liquid return structure 33 includes a mounting plate 331 and a scraper 332. The mounting plate 331 is attached to the first side 13 and has a liquid return channel 3311. The scraper 332 extends from the side of the mounting plate 331 away from the first side 13 toward the cleaning component 20. When the cleaning component 20 rotates past, it interferes with the cleaning component 20, squeezing out the dirt in the cleaning component 20, thereby improving the cleaning effect on the cleaning component 20 and increasing the cleaning efficiency of the cleaning equipment. Preferably, the scraper 332 is made of elastic rubber or silicone and makes slight contact with the surface of the cleaning component 20. When the cleaning component 20 rotates, the scraper 332 squeezes the cleaning component 20, scraping off the dirt and guiding it into the liquid return channel 3311.

[0068] Preferably, the liquid outlet structure 32 and the liquid return structure 33 are separately arranged. A pressure strip 323 is provided on the side of the liquid outlet structure 32 near the liquid return structure 33, and the pressure strip 323 is sandwiched between the mounting plate 331 and the first side 13. In this way, the design of the pressure strip 323 enhances the connection between the liquid outlet structure 32 and the liquid return structure 33, especially for the liquid outlet structure 32, increasing the supporting force for fixing it to the housing 10. In addition, the provision of the pressure strip 323 can also enhance the assembly accuracy of the liquid outlet structure 32 and the liquid return structure 33, avoiding gaps between them that could lead to leakage.

[0069] To further improve the reliability of the connection between the liquid outlet structure 32 and the liquid return structure 33 and the shell. For example... Figure 6 , Figure 7 and Figure 16As shown, the first mounting structure 11 further includes a second mounting hole 112 formed in the housing 10, the second mounting hole 112 passing through the first side 13 and the second side 14. The second mounting structure 31 also includes a hook 312, the hook 312 protruding from the side of the mounting plate 331 facing the first side 13 and passing through the second mounting hole 112, and the end of the hook 312 extending out of the second side 14 is provided with a hook portion 3121 that presses against the second side 14. In this embodiment, the hook portion 3121 can be designed as an L-shaped or U-shaped structure, achieving automatic locking through elastic deformation without additional operation. Preferably, the hook portion 3121 is also provided with a guide slope to facilitate the snap-fit ​​installation of the return liquid structure 33. In this embodiment, the double fixing of the hook 312 and the snap-fit ​​member 40 forms an assembly process of pre-positioning and then tightening, which can improve installation efficiency and ensure the installation position accuracy of the return liquid structure 33, especially suitable for scenarios where the return liquid structure 33 needs to be disassembled later for cleaning and maintenance.

[0070] When assembling the housing assembly 100, the liquid outlet structure 32 can be positioned on the first side 13 of the housing 10. Preferably, the liquid outlet structure 32 can be embedded in the mounting groove, at which point the locking member 311 on the liquid outlet structure 32 extends from the first mounting hole 111 on the housing 10. Then, the mounting plate 331 is placed against the first side 13, and the buckle extends from the second mounting hole 112. At this time, the return structure 33 presses the liquid outlet structure 32 tightly, and the locking action of the hook 312 is used to achieve the pre-positioning of the liquid outlet structure 32, the return structure 33, and the housing 10. At this time, the locking member 311 on the return structure 33 also extends from the corresponding first mounting hole 111 on the housing 10. Finally, the assembler only needs to operate from outside the housing 10, inserting the snap-fit ​​member 40 into each locking member 311 and the second side 14 to complete the assembly of the housing assembly 100. While ensuring high assembly efficiency, the snap-fit ​​component 40 also further strengthens the connection between the liquid outlet structure 32, the liquid return structure 33, and the housing 10, making the cleaning mechanism 30 more securely fixed to the housing 10. Furthermore, since the liquid return structure 33 recovers waste liquid, it may require more frequent cleaning compared to the liquid outlet structure 32, and may even need to be disassembled for later maintenance such as unclogging or replacement. The aforementioned structure, while ensuring the installation strength of the cleaning mechanism 30, also allows for easy disassembly of the liquid return structure 33 without affecting the liquid outlet structure 32, thereby improving later maintenance efficiency.

[0071] It is understandable that, since the liquid outlet structure 32 bears significant water pressure during cleaning operations, in some embodiments, the connection between the liquid outlet structure 32 and the housing 10 can be further strengthened through additional installation methods. Specifically, please refer to... Figure 6 and Figure 8The first mounting structure 11 also includes a third mounting hole 113 opened in the housing 10, the second mounting structure 31 also includes a stud 313 disposed on the liquid outlet structure 32, and the cleaning module 200 also includes a bolt 50 passing through the third mounting hole 113 and screwed to the stud 313.

[0072] In practical implementation, bolts 50 can be installed in areas of the liquid outlet structure 32 that bear high water pressure (such as near the water source interface), while snap-fit ​​fittings 40 are used for fixing in other areas, forming a hybrid connection method with snap-fit ​​fittings as the main method and bolts 50 as the auxiliary method. In parallel embodiments, the number and location of bolts 50 can be adjusted according to actual load requirements. In this embodiment, bolts 50 are used to supplement and strengthen the connection strength of the liquid outlet structure 32 in critical parts, preventing the failure of a single snap-fit ​​structure under high pressure, while retaining the quick assembly and disassembly advantages of snap-fit ​​fittings 40, thus balancing reliability and convenience.

[0073] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
