Description

Technical Field

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

[0002] Cleaning equipment includes robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment is often equipped with a central cleaning component, which is used to clean up external debris and collect it into the cleaning equipment.

[0003] However, most existing intermediate sweeping assemblies use rigid connection transmission methods for power transmission, such as directly connecting the power source to the rotating shaft of the intermediate sweeping assembly through rigid components like couplings and bushings. This rigid transmission easily leads to resonance in the intermediate sweeping assembly during operation, and generates significant noise, seriously affecting the stability of the intermediate sweeping assembly. Utility Model Content

[0004] The main objective of this application is to provide a mid-sweeping mechanism and cleaning equipment to solve the problem of resonance and noise caused by the rigid transmission of the mid-sweeping components in the prior art.

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

[0006] A housing having a receiving cavity;

[0007] A cleaning component, which is rotatably disposed in the receiving cavity;

[0008] The cleaning component and the elastic component are provided. The elastic component is disposed between the cleaning component and the driving component. Under the drive of the driving component, the elastic component drives the cleaning component to rotate around its own axis, and the elastic component can undergo torsional deformation along the rotation direction of the cleaning component.

[0009] Furthermore, the elastic component includes an elastic element that is connected between the drive assembly and the cleaning assembly via a locking element and / or a first snap-fit ​​portion.

[0010] Furthermore, the cleaning component includes a rotating shaft, and the cleaning component is rotatably disposed in the receiving cavity via the rotating shaft;

[0011] The elastic element includes an elastic sleeve, which is sleeved on the rotating shaft and connected to the rotating shaft through the locking element. The elastic sleeve is provided with a first snap-fit ​​portion, and the elastic sleeve is connected to the driving component through the first snap-fit ​​portion.

[0012] Furthermore, the elastic sleeve includes an annular sleeve body and an inner flange, the inner flange being located on the side of the annular sleeve body closer to the rotating shaft;

[0013] Wherein, the end of the rotating shaft near the drive assembly is provided with a flat portion, and the inner flange is provided with a through hole adapted to the flat portion. The inner flange is sleeved on the flat portion through the through hole and connected to the rotating shaft by the locking member; and / or,

[0014] The annular sleeve is provided with a first snap-fit ​​portion on the side opposite to the inner flange, and the annular sleeve is snapped onto the drive assembly through the first snap-fit ​​portion.

[0015] Furthermore, the drive assembly includes a power output component, one end of which is inserted into the annular sleeve near the cleaning assembly, and the outer surface of the power output component is provided with a second snap-fit ​​portion that mates with the first snap-fit ​​portion.

[0016] Furthermore, a bearing component is fitted onto the outer surface of the rotating shaft. The bearing component includes a bushing and a bearing. The bushing is fitted onto the rotating shaft, and the bearing is fitted onto the bushing and located on the side of the elastic element.

[0017] The locking element includes a locking screw that is detachably connected to the flat portion along the axial direction of the shaft and locks the inner flange to the end face of the bushing.

[0018] Furthermore, the bushing has a protective groove, and an annular boss is provided in the protective groove. The elastic sleeve is located in the protective groove. When the locking screw locks the elastic sleeve onto the bushing, the elastic sleeve abuts against the annular boss.

[0019] Furthermore, the elastic element is provided with at least one strip-shaped perforation, and the strip-shaped perforation extends circumferentially along the elastic element.

[0020] Furthermore, the elastic sleeve includes a metal sleeve, and the inner flange is provided with a plurality of first arc-shaped openings spaced apart along the outer periphery of the through hole, each of the first arc-shaped openings protruding in a direction away from the through hole;

[0021] A plurality of second arc-shaped openings are provided at the junction of the inner flange and the annular sleeve. The plurality of second arc-shaped openings are spaced apart along the outer periphery of the through hole, and each second arc-shaped opening protrudes in a direction away from the through hole.

[0022] On the other hand, this application also provides a cleaning device, which includes the above-mentioned central sweeping mechanism and a main body, wherein the central sweeping mechanism is disposed at the bottom of the main body.

[0023] When the sweeping mechanism of this application is installed on a cleaning device, the cleaning component rotates to clean the debris on the surface to be cleaned. Simultaneously, because an elastic component is provided between the cleaning component and the drive component, when the drive component drives the cleaning component to rotate, the elastic component can buffer the impact force during the transmission process through its own elastic deformation, effectively reducing vibration and lowering the possibility of resonance. It is worth mentioning that because the elastic component in this application can undergo torsional deformation along the rotation direction of the cleaning component, the buffering effect is further optimized. When the cleaning component is subjected to uneven force or the rotation direction changes instantaneously, the elastic component can quickly absorb and disperse stress through torsional deformation, avoiding local overload. At the same time, the elastic component reduces rigid collisions between the cleaning component and the drive component, thereby reducing the operating noise of the cleaning component and making the sweeping mechanism operate more smoothly. Furthermore, the elastic component can also compensate for installation and motion errors between the cleaning component and the drive component to a certain extent, effectively improving the reliability and stability of the sweeping mechanism and extending its service life.

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.

[0034] As mentioned in the background section, most existing mid-scanning assemblies use rigid connection transmission for power transmission. This rigid transmission easily leads to resonance and significant noise during operation, severely affecting the stability of the mid-scanning assembly. Therefore, the inventors of this application have designed a novel mid-scanning mechanism that solves the problem of resonance and noise caused by rigid transmission in existing mid-scanning assemblies. The mid-scanning mechanism of this application will be described in detail below with reference to the accompanying drawings.

[0035] See Figures 1 to 4 As shown, this application provides a mid-sweeping mechanism, which includes a housing 10, a cleaning component 20, a drive component 30, and an elastic component 40.

[0036] The housing 10 has a receiving cavity 101; the cleaning component 20 is rotatably disposed in the receiving cavity 101; an elastic member 40 is disposed between the cleaning component 20 and the driving component 30, and the elastic member 40 drives the cleaning component 20 to rotate around its own axis under the drive of the driving component 30, and the elastic member 40 can undergo torsional deformation along the rotation direction of the cleaning component 20. For example, the cleaning component 20 in this embodiment can be a roller brush, or it can be a roller and a mop.

[0037] In this embodiment, the accommodating cavity 101 provides a stable and protected installation space for the cleaning component 20. When the sweeping mechanism of this embodiment is installed on the cleaning equipment, the cleaning component 20 can be rotated to clean the debris on the surface to be cleaned. Meanwhile, since an elastic member 40 is provided between the cleaning component 20 and the drive component 30 in this embodiment, when the drive component 30 drives the cleaning component 20 to rotate, the elastic member 40 can buffer the impact force during the transmission process through its own elastic deformation, effectively reducing vibration and lowering the possibility of resonance. It is worth mentioning that since the elastic member 40 in this embodiment can undergo torsional deformation along the rotation direction of the cleaning component 20, the buffering effect is further optimized. When the cleaning component 20 is subjected to uneven force or the rotation direction changes instantaneously, the elastic member 40 can quickly absorb and disperse stress through torsional deformation, avoiding local overload. At the same time, the setting of the elastic member 40 reduces rigid collisions between the cleaning component 20 and the drive component 30, thereby reducing the operating noise of the cleaning component 20 and making the sweeping mechanism operate more smoothly. In addition, the elastic component 40 can also compensate for the installation and movement errors between the cleaning component 20 and the drive component 30 to a certain extent, effectively improving the reliability and stability of the central sweeping mechanism and extending its service life.

[0038] Further, see Figure 2As shown, the elastic component 40 in this embodiment includes an elastic element 41, which is connected between the driving component 30 and the cleaning component 20 via a locking element 50 and / or a first snap-fit ​​portion 60. That is, in this embodiment, the elastic element 41 can be connected between the driving component 30 and the cleaning component 20 solely via the locking element 50, solely via the first snap-fit ​​portion 60, or connected between the driving component 30 and the cleaning component 20 via both the locking element 50 and the first snap-fit ​​portion 60.

[0039] Specifically, the locking element 50 provides a reliable fixing effect, ensuring that the elastic element 41 will not easily loosen or fall off during transmission, thus guaranteeing the stability of the sweeping mechanism. The first locking part 60 facilitates the quick installation and removal of the elastic element 41, allowing maintenance or replacement of the elastic element 41 to be completed without complex tools or operations, significantly improving maintenance efficiency. The combination of the locking element 50 and the first locking part 60 ensures both a secure connection and enhanced ease of installation and removal. Simultaneously, the elastic element 41 itself possesses excellent buffering performance, which, combined with the aforementioned connection method, better absorbs the vibration and impact forces generated during the rotation of the cleaning component 20 by the drive assembly 30, further reducing resonance and noise, and extending the service life of each component.

[0040] Further, see Figures 2 to 3 As shown, the cleaning component 20 in this embodiment includes a rotating shaft 21, and the cleaning component 20 is rotatably disposed in the receiving cavity 101 via the rotating shaft 21; the elastic member 41 includes an elastic sleeve 42, which is sleeved on the rotating shaft 21 and connected to the rotating shaft 21 via a locking member 50. The elastic sleeve 42 is provided with a first snap-fit ​​portion 60, and the elastic sleeve 42 is connected to the driving component 30 via the first snap-fit ​​portion 60.

[0041] Specifically, in this embodiment, the rotating shaft 21 provides the rotation axis for the cleaning component 20, enabling the cleaning component 20 to rotate stably within the accommodating cavity 101 to complete the cleaning work. The elastic sleeve 42 is fitted onto the rotating shaft 21, precisely applying the elastic buffer function to the rotating core of the cleaning component 20, effectively absorbing the vibration generated during rotation. Simultaneously, in this embodiment, the elastic sleeve 42 is connected to the rotating shaft 21 via the locking member 50, ensuring the stability of the connection between the elastic sleeve 42 and the rotating shaft 21 and preventing loosening from affecting the buffering effect. Furthermore, the first snap-fit ​​part 60 connects the elastic sleeve 42 to the drive component 30, simplifying the connection structure and enabling rapid assembly of the elastic sleeve 42 and the drive component 30. This connection method not only ensures the stability of the central sweeping mechanism's transmission but also further reduces resonance and noise, improving the stability and reliability of the central sweeping mechanism's operation.

[0042] Further, see Figures 2 to 3As shown, the elastic sleeve 42 in this embodiment includes an annular sleeve body 421 and an inner flange 422. The inner flange 422 is located on the side of the annular sleeve body 421 near the rotating shaft 21. The rotating shaft 21 is provided with a flat portion 211 at one end near the drive assembly 30. The inner flange 422 is provided with a through hole 423 that is adapted to the flat portion 211. The inner flange 422 is sleeved on the flat portion 211 through the through hole 423 and is connected to the rotating shaft 21 by a locking member 50.

[0043] Specifically, the arrangement of the annular sleeve 421 and the inner flange 422 not only provides the elastic sleeve 42 with good elastic cushioning performance, but also provides a reliable structural foundation for the connection between the elastic sleeve 42 and the rotating shaft 21. Since the flat portion 211 of the rotating shaft 21 matches the through hole 423 on the inner flange 422, a precise positioning and limiting structure can be formed, preventing the elastic sleeve 42 from spinning freely around the rotating shaft 21 during transmission, ensuring that the power of the drive assembly 30 is stably and efficiently transmitted to the cleaning assembly 20. At the same time, this embodiment further strengthens the connection with the locking member 50, enhancing structural stability and preventing the elastic sleeve 42 and the rotating shaft 21 from loosening due to vibration during the operation of the central sweeping mechanism.

[0044] Further, see Figures 3 to 4 As shown, in this embodiment, the annular sleeve 421 is provided with a first snap-fit ​​portion 60 on the side opposite to the inner flange 422, and the annular sleeve 421 is snapped onto the drive assembly 30 through the first snap-fit ​​portion 60.

[0045] Specifically, the first snap-fit ​​part 60 enables rapid assembly of the annular sleeve 421 and the drive assembly 30. Compared with traditional screw fastening methods, this greatly shortens the installation time, reduces assembly difficulty, and facilitates batch assembly during the manufacturing process. The snap-fit ​​structure itself has a certain amount of elastic fit space, allowing for slight displacement compensation between the annular sleeve 421 and the drive assembly 30 during the operation of the central scanning mechanism. This effectively alleviates stress concentration caused by manufacturing errors, thermal expansion and contraction, and other factors, further enhancing the reliability of the central scanning mechanism. Simultaneously, this connection method makes the elastic sleeve 42 more flexible and efficient in buffering vibrations and absorbing impact forces. Combined with the elastic deformation of the elastic sleeve 42 itself, it comprehensively suppresses resonance, significantly reduces operating noise, and ensures the smooth operation of the central scanning mechanism.

[0046] Further, see Figure 2 as well as Figure 4 As shown, the drive component 30 in this embodiment includes a power output component 31. One end of the power output component 31 near the cleaning component 20 is inserted into the annular sleeve 421. The outer surface of the power output component 31 is provided with a second snap-fit ​​portion 70 that cooperates with the first snap-fit ​​portion 60.

[0047] Specifically, since the power output component 31 in this embodiment is inserted inside the annular sleeve 421, the power transmission path can be shortened, making power transmission more direct and efficient. Furthermore, the cooperation between the second locking portion 70 on the outer surface of the power output component 31 and the first locking portion 60 of the elastic sleeve 42 forms a firm and stable locking structure, effectively preventing the power output component 31 from disengaging from the elastic sleeve 42 during operation and ensuring stable power transmission. In addition, the arrangement of the first locking portion 60 and the second locking portion 70 facilitates the quick assembly and disassembly of the drive assembly 30 and the elastic sleeve 42, simplifying the installation, debugging, and subsequent maintenance of the central sweeping mechanism, thus improving the maintainability of the central sweeping mechanism.

[0048] Further, see Figure 1 As shown, the drive assembly 30 in this embodiment further includes a drive motor 32, a gearbox 33, and a power output mating component 34. The output shaft of the drive motor 32 is connected to the gear set inside the gearbox 33, and the power output mating component 34 is connected between the gearbox 33 and the power output component 31. The drive motor 32 drives the gear set inside the gearbox 33 to rotate, thereby causing the power output mating component 34 to rotate, which in turn drives the power output component 31 to rotate, and then, through the elastic sleeve 42, drives the rotating shaft 21 to rotate, thus rotating the cleaning assembly 20. Exemplarily, in this embodiment, the power output mating component 34 and the power output component 31 are connected together by a key.

[0049] Further, see Figures 3 to 4 As shown, in this embodiment, one of the first latching portion 60 and the second latching portion 70 is a latching protrusion 61, and the other is a latching groove 71. It can be understood that when the first latching portion 60 is set as a latching protrusion 61, the second latching portion 70 is set as a latching groove 71; and when the first latching portion 60 is set as a latching groove 71, the second latching portion 70 is set as a latching protrusion 61. The appendix of this embodiment... Figure 3 The first snap-fit ​​portion 60 is shown as a snap-fit ​​protrusion 61, with attached... Figure 4 The second snap-fit ​​portion 70 is shown when it is configured as a snap-fit ​​groove 71.

[0050] Specifically, the first snap-fit ​​part 60 and the second snap-fit ​​part 70 adopt a convex-concave snap-fit ​​structure, which can achieve a tight connection between the drive component 30 and the elastic sleeve 42. During installation, simply inserting the snap-fit ​​protrusion 61 into the snap-fit ​​groove 71 can quickly complete the assembly without complicated tools or cumbersome operations, significantly improving assembly efficiency. During operation, the snap-fit ​​protrusion 61 and the snap-fit ​​groove 71 fit together, which can effectively limit the relative displacement between components, ensuring that the power output component 31 stably transmits power to the elastic sleeve 42 and the cleaning component 20, avoiding transmission failure due to loose connection. At the same time, the snap-fit ​​structure with concave and convex fit allows a certain degree of elastic deformation during power transmission, which can buffer the instantaneous impact force during power transmission, absorb vibration energy, further suppress resonance, and reduce operating noise.

[0051] Further, see Figure 2 As shown, in this embodiment, a bearing component 80 is sleeved on the outer surface of the rotating shaft 21. The bearing component 80 includes a bushing 81 and a bearing 82. The bushing 81 is sleeved on the rotating shaft 21, and the bearing 82 is sleeved on the bushing 81 and located on the side of the elastic member 41. The locking member 50 includes a locking screw 51, which is detachably connected to the flat portion 211 along the axial direction of the rotating shaft 21 and locks the inner flange 422 to the end face of the bushing 81. Of course, in other embodiments of this application, the locking member 50 can also be configured as a pin, an elastic retaining ring, or a key connection, etc. Any other modifications under the concept of this application are within the protection scope of this application.

[0052] Specifically, bushing 81 provides initial support and protection for shaft 21, reducing direct friction between shaft 21 and other components; the bearing 82 reduces the resistance when cleaning component 20 rotates, allowing cleaning component 20 to rotate more smoothly around its own axis, improving rotation efficiency and reducing energy loss; and the use of locking screw 51 as locking element 50 effectively prevents elastic element 41 from axial movement or loosening during transmission, ensuring that elastic element 41 stably transmits power and buffers vibration.

[0053] Further, see Figure 2 As shown, the bushing 81 in this embodiment has a protective groove 811, and an annular boss 812 is provided in the protective groove 811. The elastic sleeve 42 is located in the protective groove 811. When the locking screw 51 locks the elastic sleeve 42 onto the bushing 81, the elastic sleeve 42 abuts against the annular boss 812.

[0054] Specifically, the protective groove 811 protects the elastic sleeve 42, preventing it from being damaged by external impacts or friction. The annular boss 812 defines the axial position of the elastic sleeve 42. When the locking screw 51 locks the elastic sleeve 42, the elastic sleeve 42 abuts against the annular boss 812, preventing axial displacement of the elastic sleeve 42 and ensuring the assembly accuracy and stability of the entire mechanism.

[0055] Further, see Figure 3 As shown, the elastic element 41 in this embodiment is provided with at least one strip-shaped perforation 90, and the strip-shaped perforation 90 extends along the circumference of the elastic element 41. Exemplarily, the strip-shaped perforation 90 in this embodiment can be one, two, or more, and this application does not make a specific limitation. It is understood that the strip-shaped perforation 90 in this embodiment can be a straight gap or an arc-shaped gap.

[0056] Specifically, the strip-shaped cutout 90 makes the structure of the elastic element 41 more flexible, allowing it to deform more easily when subjected to external forces, thereby enhancing the elasticity and flexibility of the elastic element 41. At the same time, this embodiment forms the strip-shaped cutout 90 by removing part of the material of the elastic element 41, effectively reducing the weight of the elastic element 41 without affecting its basic function.

[0057] Further, see Figure 3 As shown, the elastic sleeve 42 in this embodiment includes a metal sleeve. A plurality of first arc-shaped openings 91 are provided on the inner flange 422, spaced apart along the outer periphery of the through hole 423. Each first arc-shaped opening 91 protrudes in a direction away from the through hole 423. A plurality of second arc-shaped openings 92 are provided at the junction of the inner flange 422 and the annular sleeve body 421. These second arc-shaped openings 92 are spaced apart along the outer periphery of the through hole 423, and each second arc-shaped opening 92 protrudes in a direction away from the through hole 423. Exemplarily, the elastic sleeve 42 in this embodiment includes a spring steel sleeve.

[0058] It should be noted that in this embodiment, "the first arc-shaped opening 91 protrudes in the direction away from the through hole 423" means that, with the center of the through hole 423 as a reference, the arc-shaped edge of the first arc-shaped opening 91 protrudes outward; "the second arc-shaped opening 92 protrudes in the direction away from the through hole 423" means that, with the center of the through hole 423 as a reference, the arc-shaped edge of the second arc-shaped opening 92 protrudes outward.

[0059] Specifically, the metal sleeve itself possesses a certain strength and elasticity, while the design of the first arc-shaped opening 91 and the second arc-shaped opening 92 makes the structure of the inner flange 422 and the annular sleeve 421 more flexible. These arc-shaped openings can undergo elastic deformation when subjected to external forces, thereby further enhancing the elasticity and flexibility of the elastic sleeve 42, enabling it to better adapt to different working conditions, effectively buffering the impact and vibration during power transmission, and protecting the connected components. Simultaneously, multiple arc-shaped openings are spaced apart along the outer periphery of the through hole 423, allowing the force to be distributed more evenly across the entire structure when the elastic sleeve 42 is under stress, avoiding stress concentration. In particular, the second arc-shaped opening 92, located at the junction, effectively alleviates stress concentration at the connection between the inner flange 422 and the annular sleeve 421, reducing the risk of fatigue damage to components due to excessive local stress, and improving the service life and reliability of the elastic sleeve 42. In addition, by setting the first arc-shaped opening 91 and the second arc-shaped opening 92, some material can be removed, which effectively reduces the weight of the elastic sleeve 42 and the amount of material used, thereby reducing production costs while ensuring the basic performance of the elastic sleeve 42.

[0060] On the other hand, this application also provides a cleaning device that includes the aforementioned intermediate sweeping mechanism. Therefore, this cleaning device includes all the technical effects of the aforementioned intermediate sweeping mechanism. Since the technical effects of the intermediate sweeping mechanism have already been described in detail above, they will not be repeated here.

[0061] Specifically, the cleaning device in this embodiment also includes a main body (not shown in the accompanying drawings), and a central sweeping mechanism is provided at the bottom of the main body.

[0062] 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.

[0063] 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.
