Description

Technical Field

[0001] This utility model relates to the field of cleaning appliance technology, and more specifically, to a mid-sweeping component and cleaning equipment. Background Technology

[0002] Currently, cleaning devices such as robotic vacuum cleaners employ a floating design for their sweeper covers to ensure the sweeper remains in contact with the floor for better cleaning results. Existing floating designs for sweeper covers primarily utilize a double-layer cover structure: the outer cover is detachably fixed to the body, while the inner cover floats within the frame of the outer cover. However, this double-layer cover structure presents challenges due to its complexity and high cost. Utility Model Content

[0003] The main objective of this utility model is to provide a middle sweeping component and cleaning equipment, so as to at least solve the problems of complex structure and high cost caused by the use of a double-layer cover plate structure in the middle sweeping cover plate of the cleaning equipment.

[0004] According to one aspect of the present invention, a mid-scan assembly is provided, comprising: A housing having a receiving cavity having an opening; A cover plate is floatingly connected to the housing and covers the opening. The cover plate has a through hole corresponding to the opening, and a scraper is protruding on the side of the cover plate away from the housing. A roller brush, wherein the roller brush is disposed in the accommodating cavity and rotatably connected to the housing, and at least a portion of the roller brush passes through the through hole; A floating connection assembly, comprising a floating connector and an elastic support, wherein the floating connector is disposed between the opening and the cover plate, and the elastic support is disposed between the floating connector and the housing to provide floating support for the floating connector.

[0005] Furthermore, the first side of the cover plate is rotatably connected to the housing, and the second side of the cover plate opposite to the first side is floatingly connected to the housing via a floating connection assembly, and the scraper is disposed on the second side of the cover plate.

[0006] Furthermore, the scraper has a first side and a second side disposed opposite to each other, the first side of the scraper being disposed close to the surface to be cleaned, and the second side of the scraper extending toward the housing to cover the gap between the second side of the cover plate and the housing.

[0007] Furthermore, the floating connector has a first end and a second end that are disposed opposite to each other. The first end of the floating connector is rotatably connected to the housing, and the second end of the floating connector is engaged with the second side of the cover plate.

[0008] Furthermore, one of the second end of the floating connector and the cover plate is provided with a first slot, and the other end is provided with a buckle that engages with the first slot.

[0009] Furthermore, along the direction from the bottom to the opening of the first slot, the distance between the first slot wall facing away from the housing and the housing gradually increases. When the floating connector is subjected to an external force to overcome the supporting elastic force of the elastic support, the buckle slides along the first slot wall to disengage from the first slot.

[0010] Furthermore, the elastic support includes at least one of a spring, a sheet spring, a torsion spring, and a soft rubber pad.

[0011] Furthermore, the roller brush includes a main body and a connector, both ends of the main body are rotatably connected to the connector, and the connector is detachably connected to the housing.

[0012] Furthermore, the connector is provided with a snap-fit ​​part and a pressing part connected to the snap-fit ​​part, and the housing is provided with a second slot that snaps into the snap-fit ​​part. The pressing part is configured to drive the snap-fit ​​part to disengage from the second slot or engage with the second slot when subjected to external force.

[0013] On the other hand, the present invention also provides a cleaning device, which includes the aforementioned intermediate sweeping component.

[0014] In this invention, a floating connector is provided between the cover plate and the housing of the central sweeping assembly, enabling a floating connection between the cover plate and the housing. An elastic support is provided to float the connector, allowing the cover plate to adaptively adjust to the undulations of the surface to be cleaned. This ensures that the scraper on the side of the cover plate away from the housing remains in close contact with the ground, improving the removal of dirt from the surface. The roller brush is rotatably connected to the housing. Compared to the existing technology that uses a double-layer cover plate structure to achieve a floating cover, the structure of this application is simpler and has lower manufacturing costs. The single-layer floating connection of the cover plate in this embodiment optimizes the structure of the central sweeping assembly and improves the reliability of the cleaning equipment.

[0020] In related technologies, the floating design of the sweeping cover plate in cleaning equipment adopts a double-layer cover plate structure. The outer cover plate is detachably fixed to the machine body, while the inner cover plate is floating within the middle frame of the outer cover plate. This structure is relatively complex and has high manufacturing costs. Therefore, this utility model provides a sweeping component and cleaning equipment. By setting the cover plate of the sweeping component to float and connect with the housing, the roller brush can be independently and rotatably installed in the housing. The structure is simple, low-cost, and easier to assemble.

[0021] See Figures 1 to 10 As shown, according to an embodiment of this application, a mid-scan assembly is provided, including a housing 10, a cover plate 20, a roller brush 30, and a floating connection assembly 40.

[0022] The housing 10 has a receiving cavity 11 with an opening 111. A cover plate 20 is floatingly connected to the housing 10 and covers the opening 111. The cover plate 20 has a through hole 21 corresponding to the opening 111, and a scraper strip 22 protrudes from the side of the cover plate 20 away from the housing 10. A roller brush 30 is disposed in the receiving cavity 11 and rotatably connected to the housing 10, with at least a portion of the roller brush 30 passing through the through hole 21. The floating connection assembly 40 includes a floating connector 41 and an elastic support 42. The floating connector 41 is disposed between the opening 111 and the cover plate 20, and the elastic support 42 is disposed between the floating connector 41 and the housing 10 to provide floating support for the floating connector 41.

[0023] Understandably, the sweeping component in this embodiment is mainly used in cleaning equipment such as sweeping robots, vacuum cleaners, and floor scrubbers. By installing the sweeping component at the bottom of the cleaning equipment, the surface waiting to be cleaned on the ground can be swept, reducing the dirt residue on the surface to be cleaned and collecting the dirt in a concentrated manner.

[0024] Specifically, in this embodiment, the cover plate 20 and the housing 10 are floatingly connected by a floating connector 41. The floating connector 41 floats through an elastic support 42. When the cleaning equipment is cleaning the surface to be cleaned, under the action of the floating connector 41 and the elastic support 42, the scraper 22 protruding on the side of the cover plate 20 away from the housing 10 can better fit with the surface to be cleaned. Even if there are obstacles or the surface to be cleaned is uneven, the scraper 22 can still fit tightly with the surface to be cleaned, and can better scrape off the dirt on the surface to be cleaned, thus improving the cleaning effect of the middle sweeping component of the cleaning equipment. Since a roller brush 30 is rotatably disposed in the accommodating cavity 11 of the housing 10, and at least a portion of the roller brush 30 passes through the through hole of the cover plate 20, when the scraper 22 is in close contact with the surface to be cleaned to clean dirt under the action of the floating connecting assembly 40, the roller brush 30 also closely contacts the surface to be cleaned because it passes through the through hole of the cover plate 20. It works with the scraper 22 to roll the dirt scraped off by the scraper 22 into the accommodating cavity 11, and finally collects it through the dust collection structure connected to the accommodating cavity 11, further improving the cleaning effect of the cleaning equipment.

[0025] Specifically, in this embodiment, a flexible pad 23 is also provided on the side of the cover plate 20 away from the housing 10. When the cleaning equipment performs cleaning work, the flexible pad 23 also contacts the surface to be cleaned to support the central sweeping component. When the flexible pad 23 contacts the surface to be cleaned, it can buffer the pressure of the cover plate 20 on the ground through its own deformation, preventing the scraper 22 from scratching the surface of the surface to be cleaned.

[0026] Optionally, the flexible pad 23 in this embodiment includes a wool pad. Using a wool pad as the flexible pad 23 can not only buffer pressure and prevent scratches on the surface to be cleaned, but also the wool pad is durable, easy to clean, and can be adapted to different floor materials.

[0027] Furthermore, the first side of the cover plate 20 is rotatably connected to the housing 10, and the second side of the cover plate 20 opposite to the first side is floatingly connected to the housing 10 via a floating connection assembly 40. The scraper 22 is disposed on the second side of the cover plate 20.

[0028] In this embodiment, the first side of the cover plate 20 is rotatably connected to the housing 10, forming a fixed pivot point between the cover plate 20 and the housing 10. The first side of the cover plate 20, opposite to the second side, is also rotatably connected to the housing 10 via a floating connection assembly 40. This allows the cover plate 20 to rotate flexibly relative to the housing 10 within a certain range, with the scraper 22 positioned precisely on the second side. Because the scraper 22 is located on the second side of the cover plate 20, when the surface to be cleaned is uneven, the second side of the cover plate 20 can float relative to the first side of the cover plate 20 along the direction of rotation, ensuring that the scraper 22 maintains stable contact with the surface to be cleaned, thus guaranteeing the cleaning effect and preventing any missed cleaning areas. When the cleaning equipment encounters obstacles or uneven ground, the floating connection between the second side of the cover plate 20 and the housing 10 can buffer the impact, preventing the scraper 22 from being damaged by rigid collision.

[0029] Optionally, in this embodiment, the scraper 22 is detachably fixed to the cover plate 20 by the scraper support 24 to improve the reliability of the scraper 22 and facilitate the replacement or cleaning of the scraper 22, thus ensuring the cleaning effect of the scraper 22.

[0030] Optionally, the rotatable connection between the first side of the cover plate 20 and the housing 10 can be achieved by at least one of the following connection methods: shaft-hole connection, hinge connection, or pin connection. In this embodiment, the first side of the cover plate 20 and the housing 10 are connected by a shaft-hole connection. The cover plate 20 is provided with a rotating shaft 25, and the housing 10 is provided with a shaft hole 15. The rotation of the cover plate 20 relative to the housing 10 can be achieved by the rotating engagement of the rotating shaft 25 and the shaft hole 15.

[0031] Optionally, the first side of the cover plate 20 can be floatingly connected to the housing 10 using a floating connection component 40. That is, both the first and second sides of the cover plate 20 are floatingly connected to the housing through the floating connection component 40. In this way, the entire cover plate 20 can float relative to the housing 10, which can better adapt to different surfaces to be cleaned, ensure the uniformity of contact between the scraper 22 and the surface to be cleaned, and improve the cleaning effect.

[0032] refer to Figure 5 As shown, the scraper 22 has a first side and a second side disposed opposite to each other. The first side of the scraper 22 is disposed close to the surface to be cleaned, and the second side of the scraper 22 extends toward the housing 10 to cover the gap between the second side of the cover plate 20 and the housing 10.

[0033] Understandably, in this embodiment, when assembling the cover plate 20 and the housing 10, a certain assembly gap is unavoidable at the connection between the cover plate 20 and the housing 10, resulting in uneven negative pressure at the suction port of the accommodating cavity 11, poor negative pressure effect, and poor cleaning effect. Therefore, in this embodiment, by extending the second side of the scraper 22 to the gap between the second side of the cover plate 20 and the housing 10 and covering the gap, the negative pressure of the accommodating cavity 11 can be prevented from leaking from the gap, improving the sealing of the accommodating cavity 11 and ensuring the cleaning effect of the sweeping assembly. The first side of the scraper 22, opposite to the second side, is located close to the surface to be cleaned, and the first side of the scraper 22 at least partially protrudes from the through hole 21, so that the scraper can better adhere to the surface to be cleaned during the cleaning process, ensuring the cleaning effect of the scraper 22 on the surface to be cleaned.

[0034] Furthermore, the floating connector 41 has a first end and a second end that are disposed opposite to each other. The first end of the floating connector 41 is rotatably connected to the housing 10, and the second end of the floating connector 41 is engaged with the second side of the cover plate 20.

[0035] In this embodiment, since the elastic support 42 is disposed between the floating connector 41 and the housing 10, and provides floating support for the floating connector 41, when the elastic force of the elastic support 42 acts on the floating connector 41, the floating connector 41 rotates relative to the first end with the connection point between its first end and the housing 10 as the fulcrum. Because the second end of the floating connector 41 is engaged with the cover plate 20, when the floating connector 41 floats and rotates under the action of the elastic support 42, it also drives the cover plate 20 to float and rotate, thus achieving the floating of the cover plate 20. The elastic support 42, disposed between the floating connector 41 and the housing 10, normally applies a supporting force towards the floating connector 41 through its own pre-tightening force, ensuring that the scraper 22 on the second side of the cover plate 20 maintains contact pressure with the surface to be cleaned, thereby improving the cleaning effect of the cleaning equipment in this embodiment.

[0036] It should be noted that the rotatable connection between the first end of the floating connector 41 and the housing 10 in this embodiment can be achieved through at least one of the following connection methods: shaft-hole fit, hinge connection, or pin connection. This application does not impose specific limitations on this.

[0037] Furthermore, one of the second end of the floating connector 41 and the cover plate 20 is provided with a first slot 411, and the other is provided with a buckle 412 that engages with the first slot 411.

[0038] In this embodiment, the second end of the floating connector 41 is connected to the cover plate 20 via a snap-fit ​​connection between the first slot 411 and the buckle 412. This snap-fit ​​structure is simple and improves the production efficiency of the mid-sweeping assembly in this embodiment. The snap-fit ​​connection between the buckle 412 and the first slot 411 forms a reliable mechanical connection, ensuring that the rotational movement of the floating connector 41 is accurately transmitted to the second side of the cover plate 20. This ensures that the scraper 22 can float with the cover plate 20 to closely adhere to the surface to be cleaned, guaranteeing a good cleaning effect.

[0039] refer to Figure 5 As shown, along the direction from the bottom 4111 of the first slot 411 to the opening 4112, the distance between the first slot wall 4113 of the first slot 411 and the housing 10 gradually increases. When the floating connector 41 is subjected to an external force to overcome the supporting elastic force of the elastic support 42, the buckle 412 slides along the first slot wall 4113 to disengage from the first slot 411.

[0040] In this embodiment, along the direction from the bottom 4111 to the opening 4112 of the first slot 411, the distance between the first slot wall 4113 of the first slot 411 and the housing 10 gradually increases. Therefore, the first slot wall 4113 can serve as a guide surface for the movement of the buckle 412 relative to the first slot 411, making the relative sliding between the buckle 412 and the first slot 411 smoother, reducing the sliding friction between them, and making the engagement between the buckle 412 and the first slot 411 smoother. This further facilitates the smoother disassembly and installation of the cover plate 20 and the floating connector 41. When the floating connector 41 is subjected to an external force to overcome the supporting elastic force of the elastic support 42, such as pressing the floating connector 41 from the top, the floating connector 41 rotates relative to the housing 10, causing the first slot 411 of the floating connector 41 to slide relative to the buckle 412 of the cover plate 20. Under the guidance of the first slot wall 4113, the buckle 412 slides relative to the first slot 411 until the buckle 412 disengages from the first slot 411. This not only enables the cover plate 20 to float relative to the housing 10, but also allows the cover plate 20 to be rotated and opened to facilitate cleaning of the accommodating cavity 11 or maintenance of the roller brush 30.

[0041] refer to Figure 5As shown, a snap-fit ​​guide surface 4121 is provided between the end of the snap-fit ​​412 and its bottom surface. When the floating connector 41 is subjected to an external force to overcome the supporting elastic force of the elastic support member 42, the snap-fit ​​guide surface 4121 of the snap-fit ​​412 slides against the bottom surface of the first slot 411 to disengage from the first slot 411. Therefore, when the snap-fit ​​412 slides relative to the first slot 411, the sliding friction between the snap-fit ​​guide surface 4121 and the bottom surface of the first slot 411 is small, allowing the snap-fit ​​412 to slide more smoothly within the first slot 411, thus improving the floating effect of the housing 10.

[0042] Optionally, both the first groove wall 4113 and the snap-fit ​​guide surface 4121 in this embodiment can be configured as curved surfaces or inclined surfaces. Curved surfaces or inclined surfaces enable the snap-fit ​​412 to slide smoothly through the first groove 411, reducing the resistance when the snap-fit ​​412 slides, improving the smoothness of the cover plate 20 floating and the convenience of operation when separating the cover plate 20.

[0043] refer to Figure 4 and Figure 5 As shown, a guide space 12 exists between the floating connector 41 and the housing 10. A rotation guide surface 16 is provided on the housing 10 within this guide space 12. When the floating connector 41 rotates within this guide space 12, its bottom end adheres to the rotation guide surface 16 and rotates relative to the housing 10. When the floating connector 41 rotates to a predetermined position, the latch 412 disengages from the first latch 411. At this point, the cover plate 20 and the housing 10 are no longer a floating structure; that is, the second side of the cover plate 20 detaches from the housing 10. The bottom end of the floating connector 41 adhering to the rotation guide surface 16 during rotation prevents jamming or wear during rotation, improves the smoothness of rotation of the floating connector 41 under external force or the elastic force of the elastic support 42, and ensures the reliability of the floating function of the cover plate 20.

[0044] Furthermore, the elastic support 42 includes at least one of a spring, a spring sheet, a torsion spring, and a soft rubber pad. When the elastic support 42 uses a spring, the spring can provide stable support force through its own linear elastic deformation. When the elastic support 42 uses a spring sheet, the spring sheet achieves directional deformation with a flat structure, which can constrain the floating direction of the cover plate 20 in a confined space. When the elastic support 42 uses a torsion spring, the torsion spring can directly adapt to rotational floating through torsional torque, providing a constant restoring force and ensuring contact pressure at different angles. When the elastic support 42 uses a soft rubber pad, the soft rubber pad can absorb vibration and reduce noise through damping characteristics, reducing the noise caused by the elastic deformation of the elastic support 42 when the cover plate floats or the frictional noise between the elastic support 42 and the floating connector 41 and the housing 10.

[0045] like Figure 4 and Figure 5The diagram shows the structure of the elastic support 42 when a spring is used. When the first slot 411 and the buckle 412 of the floating connector 41 are engaged and the floating connector 41 is not subjected to external force, the spring is in a free state. At this time, if the cleaning equipment encounters an obstacle or an uneven surface during cleaning, the cover plate 20 will contact the obstacle or the surface to be cleaned, thereby causing the buckle 412 to move in the first slot 411 on the floating connector 41, causing the floating connector 41 to compress the spring, thus achieving adaptive floating during the cleaning process. When it is necessary to unlock the engagement between the floating connector 41 and the cover plate 20, a large compressive force is manually applied to the floating connector 41 or the cover plate 20. At this time, the deformation of the spring increases, causing the buckle 412 to disengage from the first slot 411, and the side of the cover plate 20 closest to the floating connector 41 to detach from the housing 10. This makes the disassembly and installation of the cover plate 20 and the housing 10 more convenient, and avoids the cover plate 20 from detaching from the housing 10 when encountering obstacles, thus preventing it from affecting the operation of the cleaning equipment.

[0046] refer to Figure 5 and Figure 6 As shown, in this embodiment, the floating connector 41 has a first support portion 413 on the side near the elastic support member 42, and the housing 10 has a second support portion 13 on the first side near the elastic support member 42. One end of the elastic support member 42 is supported on the floating connector 41 by the first support portion 413, and the other end is supported on the housing 10 by the second support portion 13. This embodiment provides support for the elastic support member 42 by providing the first support portion 413 on the floating connector 41 and the second support portion 13 on the housing 10, preventing the elastic support member 42 from shifting during the floating of the cover plate 20 or during the application of external force to the floating connector 41, thus ensuring the floating effect of the cover plate 20.

[0047] Preferably, when the elastic support 42 in this embodiment is a spring, the first support portion 413 can be configured as a groove or a protrusion, and the second support portion 13 can also be configured as a groove or a protrusion to support and limit the two ends of the elastic support 42 and prevent the elastic support 42 from shifting.

[0048] refer to Figure 8 As shown, the roller brush 30 includes a main body 31 and a connector 32. Both ends of the main body 31 are rotatably connected to the connector 32, and the connector 32 is detachably connected to the housing 10.

[0049] In this embodiment, by providing connectors 32 at both ends of the main body 31 of the roller brush 30, the connectors 32 are detachably connected to the housing 10. During assembly, the roller brush 30 can be fixed in the accommodating cavity 11 first, and the cover plate 20 does not play the role of fixing the roller brush 30. Under the premise of ensuring that the cover plate 20 has a floating function, the roller brush can be detachably fixed and installed, so that the roller brush 30 will not swing randomly in the accommodating cavity 11. When it is necessary to disassemble and clean the roller brush 30, only the roller brush 30 can be disassembled without disassembling the cover plate 20.

[0050] refer to Figure 9 As shown, the connector 32 is provided with a snap-fit ​​part 321 and a pressing part 322 connected to the snap-fit ​​part 321. The housing 10 is provided with a second slot 14 that engages with the snap-fit ​​part 321. The pressing part 322 is configured to drive the snap-fit ​​part 321 to disengage from the second slot 14 or engage with the second slot 14 when subjected to external force.

[0051] In this embodiment, the engagement of the snap-fit ​​part 321 with the second slot 14 provides a reliable mechanical lock for the roller brush 30, allowing it to rotate stably within the receiving cavity 11. By providing a pressing part 322 connected to the snap-fit ​​part 321, the pressing part 322 undergoes elastic deformation under external force, thereby moving the snap-fit ​​part 321. This allows the pressing part 322 to either disengage from or engage with the second slot 14, achieving a detachable connection between the roller brush 30 and the housing 10. This ensures stable rotation of the roller brush 30 within the receiving cavity 11 and facilitates easy disassembly and cleaning, improving the reliability of the mid-sweeping assembly in this embodiment.

[0052] On the other hand, this application also discloses a cleaning device, referenced Figure 10 As shown, the cleaning device 50 includes the aforementioned intermediate sweeping assembly. Therefore, the cleaning device 50 includes all the technical effects of the aforementioned intermediate sweeping assembly. Since the technical effects of the intermediate sweeping assembly have 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 utility model.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
