[0002] Cleaning devices such as robot vacuums and robot mops typically use cleaning mechanisms like roller brushes to clean the surface. During the cleaning process, the roller brushes can easily get tangled with hair and other foreign objects, thus affecting the cleaning effectiveness of the mechanism.
[0003] Existing cleaning systems typically include a cutting assembly to cut away foreign objects such as hair. This cutting assembly consists of a drive unit and a cutting component, which, driven by the drive unit, removes hair tangled on the roller brush. However, existing drive units are complex in structure and expensive. Utility Model Content
[0004] The main objective of this application is to provide a cleaning mechanism and cleaning equipment to solve the problem that the drive component in the cutting assembly of the existing cleaning mechanism has a complex structure and high cost.

The second gear component includes a worm wheel and a plurality of transmission gears. The worm wheel meshes with the worm gear and the transmission gears respectively, and the axis of the worm wheel is perpendicular to the axis of the worm gear. The plurality of transmission gears are arranged sequentially and mesh in a direction parallel to the axis of the cleaning body, and the axes of the plurality of transmission gears are all parallel to the axis of the worm wheel. Among them, in the direction away from the worm wheel, the transmission gear closest to the first gear component meshes with the worm wheel, and the transmission gear farthest from the first gear component is connected to the crank-slider assembly.
[0008] Furthermore, the crank-slider assembly includes: A slider body, which is disposed in the cavity and can reciprocate along an axis parallel to the cleaning body; The crank body has a first end hinged to the second gear component, and the hinge position of the crank body and the second gear component is offset from the geometric center of the second gear component. The second end of the crank body, opposite to the first end, is hinged to the slider body. When the second gear component rotates, it drives the crank body to move, thereby driving the slider body to reciprocate along an axis parallel to the cleaning body.
[0009] Furthermore, one of the slider body and the cutting component is provided with a snap-fit part, and the other of the two is provided with a slot that matches the snap-fit part.
[0010] Furthermore, the cutting assembly includes: A first cutting element is disposed on the cleaning body and extends along an axis parallel to the cleaning body, and a portion of the first cutting element protrudes from the outer surface of the cleaning body. The second cutting element is stacked on top of the first cutting element and connected to the crank-slider assembly so that it reciprocates along an axis parallel to the cleaning body under the drive of the crank-slider assembly, and a portion of the second cutting element protrudes from the outer surface of the cleaning body.
[0011] Furthermore, the outer surface of the cleaning body is provided with a plurality of comb teeth, which are spaced apart along a direction parallel to the axis of the cleaning body and extend circumferentially along the cleaning body. The length of each comb tooth protruding from the outer surface of the cleaning body is greater than the length of the first cutting member and the second cutting member protruding from the outer surface of the cleaning body, and each comb tooth has a clearance notch for avoiding the first cutting member and the second cutting member.
[0012] Furthermore, the comb tooth component includes a first comb tooth segment and a second comb tooth segment, the cleaning body includes a first body and a second body, the first comb tooth segment is disposed on the outer surface of the first body, the second comb tooth segment is disposed on the outer surface of the second body and surrounds the first comb tooth segment to form the avoidance gap, and the portion of the cutting component protruding from the outer surface of the cleaning body is located between the first comb tooth segment and the second comb tooth segment.

[0014] On the other hand, this application also provides a cleaning device, which includes the cleaning mechanism described above.
[0015] This application incorporates a gear assembly within the cavity, connecting it to an input component. As the cleaning unit rotates, the gear assembly moves relative to the input component, thus achieving its own rotation. This eliminates the need for a separate power source and complex power connection structure for the gear assembly. It fully utilizes the rotational characteristics of the cleaning unit, driven by a pre-defined drive structure such as a motor, allowing the gear assembly to operate synchronously with the cleaning unit. Furthermore, the gear transmission characteristics smoothly convert the gear assembly's rotation into the driving force for the cutting component. When the cleaning equipment is performing cleaning operations, if hair becomes entangled on the surface of the cleaning unit or if it comes into contact with long, thin foreign objects, the gear assembly quickly transmits power to the reciprocating motion component. Driven by the gear assembly, the reciprocating motion component moves, causing the cutting component to reciprocate at least partially along a direction parallel to the cleaning unit's axis, thus cutting the foreign object and preventing it from becoming entangled on the cleaning unit. This power transmission path, achieved through a gear assembly, simplifies the overall structure of the cleaning mechanism, reducing the number of parts and lowering production and maintenance costs.

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.
[0021] As mentioned in the background section, existing cleaning mechanisms typically include a cutting component to cut away foreign objects such as hair. The cutting component comprises a drive unit and a cutting unit, which, driven by the drive unit, cleans the hair entangled on the roller brush. However, existing drive units are complex in structure and expensive. Therefore, the inventors of this application have designed a new cleaning mechanism that at least solves the problem of complex structure and high cost of the drive unit in the cutting component of existing cleaning mechanisms. The cleaning mechanism of this application will be described in detail below with reference to the accompanying drawings.
[0022] See Figures 1 to 4 As shown, according to an embodiment of this application, a cleaning mechanism is provided, which includes a cleaning body 10, a cutting component 20, an input component 90, a reciprocating motion component 200, and a gear assembly 30.
[0023] The cleaning body 10 includes a cavity 101 and a drive end 102 for connection with a predetermined drive structure. The cleaning body 10 can rotate around its own axis under the drive of the predetermined drive structure. A cutting component 20 is disposed on the cleaning body 10 and reciprocates at least partially along an axis parallel to the cleaning body 10 to cut foreign objects. An input component 90 is at least partially disposed on the cavity 101. A reciprocating component 200 is movably disposed on the cavity 101 and connected to the cutting component 20. A gear assembly 30 is disposed on the cavity 101 and connected to both the reciprocating component 200 and the input component 90. The gear assembly 30 rotates with the cleaning body 10 to move relative to the input component 90, thereby driving the reciprocating component 200 to move, which in turn drives the cutting component 20 to reciprocate at least partially along an axis parallel to the cleaning body 10. It is understood that foreign objects in this application include hair wrapped around the cleaning body 10 or long strips of debris.
[0024] When the cleaning mechanism of this application is installed on a cleaning device, such as a robot vacuum cleaner or a robot mop, it can be connected to the drive end 102 of the cleaning body 10 via a predetermined drive structure such as a motor to drive the cleaning body 10 to rotate. During the rotation of the cleaning body 10, the gear assembly 30 rotates synchronously with the cleaning body 10, and moves relative to the input component 90 to realize the operation of the gear assembly 30 itself, eliminating the need for a complex power transmission structure. At the same time, the precision and reliability of gear transmission can stably drive the cutting component 20 to move. When hair is wrapped around the cleaning body 10, the gear assembly 30 drives the reciprocating motion component 200 to move, thereby driving the cutting component 20 to reciprocate at least partially along a direction parallel to the axis of the cleaning body 10 to complete the cutting action of hair and other foreign objects. Throughout the process, the moving power of the cutting component 20 depends entirely on the force transmitted from the rotation of the cleaning body 10 to the gear assembly 30, eliminating the need for a separate complex drive component, reducing the number of parts used, and lowering production and maintenance costs. Meanwhile, due to the simple structure of the gear assembly 30, when replacing damaged parts, it is not necessary to replace the entire complex transmission system; only the corresponding gear assembly 30 needs to be replaced. This not only reduces repair time but also lowers the user's subsequent maintenance costs. Furthermore, the gear assembly 30 in this embodiment does not require complex spatial angle adjustments or special curved surface machining processes during manufacturing, effectively reducing raw material waste and production costs. Simultaneously, the gear assembly 30 can achieve multi-stage reduction within a confined cavity 101, ensuring both transmission accuracy and torque transmission efficiency while maximizing the use of limited space to meet the transmission requirements for high reduction ratios within a confined space.
[0025] In other words, by setting a gear assembly 30 within the cavity 101 and connecting it to the input component 90, the gear assembly 30 can move relative to the input component 90 as the cleaning body 10 rotates, thus achieving its own rotation. This process eliminates the need for an independent power source and complex power connection structure for the gear assembly 30. It fully utilizes the rotational characteristics of the cleaning body 10 driven by a predetermined drive structure such as a motor, allowing the gear assembly 30 to operate synchronously with the cleaning body 10. Furthermore, the characteristics of gear transmission smoothly convert the rotation of the gear assembly 30 into a driving force that moves the cutting component 20. When the cleaning equipment is performing cleaning operations, if hair becomes entangled on the surface of the cleaning body 10 or if it comes into contact with long, thin foreign objects, the gear assembly 30 can quickly transmit power to the reciprocating motion component 200. Driven by the gear assembly 30, the reciprocating motion component 200 moves to drive the cutting component 20 at least partially along a direction parallel to the axis of the cleaning body 10, thus completing the cutting action on the foreign objects and preventing them from becoming entangled on the cleaning body 10. This power transmission path, achieved through gear assembly 30, simplifies the overall structure of the cleaning mechanism, thereby reducing the number of parts used and lowering production and maintenance costs.
[0026] Further, see Figure 2 As shown, the reciprocating motion component 200 in this embodiment includes a crank-slider assembly 40, which is movably disposed in the cavity 101 and connected to the cutting component 20. The gear assembly 30 includes a first gear component 31 and a second gear component 32. The first gear component 31 is disposed in the input component 90, and its axis is parallel to the axis of the cleaning body 10. The axis of the second gear component 32 is perpendicular to the axis of the cleaning body 10. The second gear component 32 meshes with the first gear component 31 and is connected to the crank-slider assembly 40. The second gear component 32 can rotate with the cleaning body 10 and rotate around its own axis under the action of the first gear component 31. When the second gear component 32 rotates, it drives the crank-slider assembly 40 to move, thereby driving the cutting component 20 to reciprocate along a direction parallel to the axis of the cleaning body 10.
[0027] Specifically, the crank-slider assembly 40 provides stable motion guidance for the movement of the cutting assembly 20, smoothly converting the rotational power of the gear assembly 30 into the linear movement required by the cutting assembly 20, preventing the cutting assembly 20 from deviating or jamming during movement. In the gear assembly 30, the first gear component 31, whose axis is parallel to the axis of the cleaning body 10, can better receive the rotational power of the cleaning body 10, ensuring that the power transmission direction matches the operating direction of the cleaning body 10 and reducing power loss. As for the second gear component 32, whose axis is perpendicular to the axis of the cleaning body 10, on the one hand, it achieves flexible conversion of the power direction through meshing with the first gear component 31, allowing the rotational power of the cleaning body 10 to be smoothly transmitted to the second gear component 32. On the other hand, through its connection with the crank-slider assembly 40, it rotates around its own axis while rotating with the cleaning body 10, thereby driving the crank-slider assembly 40 to move in a direction parallel to the axis of the cleaning body 10, and finally driving the cutting assembly 20 to complete the cutting action.
[0028] In other words, when the second gear component 32 rotates synchronously with the cleaning body 10, it can obtain stable power through its meshing relationship with the first gear component 31. During its synchronous rotation with the cleaning body 10, it rotates around its own axis under force, thereby driving the crank-slider assembly 40 to reciprocate in a direction parallel to the axis of the cleaning body 10. This, in turn, drives the cutting assembly 20 to move synchronously to cut hair and other foreign objects entangled on the cleaning body 10. The entire transmission process can be achieved without an additional drive control module, simplifying the motion control logic and avoiding the complex debugging problems caused by the coordination of multiple drive components.
[0029] Further, see Figures 2 to 4As shown, in one embodiment of this application, the input component 90 includes an input shaft 91, which extends along a direction parallel to the axis of the cleaning body 10. The first end of the input shaft 91 is connected to the end of the cleaning body 10 away from the drive end 102. The first gear component 31 includes a first bevel gear 311, which is disposed at the second end of the input shaft 91 opposite to the first end, and the axis of the first bevel gear 311 is parallel to the axis of the cleaning body 10. The second gear component 32 includes multiple sets of gears 321, which are arranged sequentially along a direction parallel to the axis of the cleaning body 10. The axis of gear set 321 is perpendicular to the axis of the first bevel gear 311. Gear set 321 includes a first gear body 3211 and a second gear body 3212 coaxially arranged. The number of teeth in the first gear body 3211 is greater than the number of teeth in the second gear body 3212. Along the direction away from the first gear component 31, the first gear body 3211 of the latter set meshes with the second gear body 3212 of the former set. The first gear body 3211 closest to the first gear component 31 meshes with the first bevel gear 311, and the first gear body 3211 farthest from the first gear component 31 is connected to the crank-slider assembly 40. It is worth noting that the first gear body 3211 closest to the first gear component 31 is a bevel gear. It should be noted that in this application, "the latter set" and "the former set" refer to the gear set 321 that is closer to the crank-slider assembly 40 and farther from the first gear component 31 in two adjacent sets of gear sets 321, defined as the "later set" and the gear set 321 that is farther from the crank-slider assembly 40 and closer to the first gear component 31, defined as the "former set".
[0030] Specifically, in this embodiment, multiple gear sets 321 are arranged sequentially along the axial direction of the cleaning body 10. This not only makes reasonable use of the limited space within the cavity 101 but also avoids the chaotic distribution of the second gear components 32 within the cavity 101, achieving a regularized structural layout. Meanwhile, since the first gear body 3211 and the second gear body 3212 are coaxially arranged in this embodiment, and the number of teeth in the first gear body 3211 is greater than the number of teeth in the second gear body 3212, when the gear set 321 rotates around its own axis, the first gear body 3211 and the second gear body 3212 can maintain the same rotational angular velocity synchronously. However, during power transmission, the difference in the number of teeth will result in different linear velocity and torque output characteristics. Based on this, this embodiment meshes the later set of first gear bodies 3211 with the earlier set of second gear bodies 3212. This arrangement allows the smaller second gear body 3212 in the earlier set to drive the larger first gear body 3211 in the later set to rotate, thereby achieving multi-stage speed reduction by utilizing the transmission characteristics of a small gear driving a large gear, and thus achieving a step-by-step amplification of the driving torque. Since the first gear body 3211, which is furthest from the first gear component 31, is connected to the crank-slider assembly 40, the large torque amplified by multi-stage reduction can be precisely transmitted to the crank-slider assembly 40. This provides sufficient and stable driving force for the movement of the crank-slider assembly 40, ensuring that the slider can overcome load resistance and achieve smooth reciprocating motion. Furthermore, since the crank-slider assembly 40 is connected to the cutting assembly 20, the smooth drive of the crank-slider assembly 40 will further increase the cutting torque of the cutting assembly 20, ultimately significantly improving the cutting effect and reliability of the cutting assembly 20.
[0031] Furthermore, this multi-stage reduction design, combined with the regular arrangement of gear sets 321 along a direction parallel to the axis of the cleaning body 10, not only allows for precise planning of the transmission path within the limited space inside the equipment, shortening the power transmission distance, but also reduces energy loss during power transmission by minimizing gear meshing clearance and transmission interference, thereby improving overall transmission efficiency. It is understood that in this embodiment, the crank-slider assembly 40 is driven to move through the progressive meshing of multiple gear sets 321, and then the crank-slider assembly 40 drives the cutting assembly 20 to move at least part of its stroke. The entire transmission mechanism is compact and has a clear transmission link, eliminating the need for complex transition components, thus simplifying the assembly process and effectively controlling manufacturing and maintenance costs.
[0032] Specifically, in this embodiment, when the cleaning body 10 rotates around its own axis, multiple gear sets 321 and the crank-slider assembly 40 rotate synchronously with the cleaning body 10. Since the first gear body 3211, closest to the first gear component 31, meshes with the first bevel gear 311, the first gear body 3211, rotating with the cleaning body 10, rotates under the action of the first bevel gear 311. This drives the second gear body 3212, coaxially arranged with the first gear body 3211, to rotate, and subsequently drives the remaining gear sets 321 to rotate. Finally, the first gear body 3211, furthest from the first gear component 31, transmits power to the crank-slider assembly 40 connected to it, causing the crank-slider assembly 40 to reciprocate along a direction parallel to the axis of the cleaning body 10. This, in turn, drives the cutting assembly 20 to reciprocate along a direction parallel to the axis of the cleaning body 10 to cut foreign objects.
[0033] For example, the gear set 321 in this embodiment includes two, three, or more sets; this application does not impose a specific limitation. Figure 3 The diagram shows the case where gear set 321 includes three sets.
[0034] It is worth mentioning that in this embodiment, both the first gear body 3211 and the second gear body 3212 are made of rubber teeth.
[0035] Further, see Figure 5 As shown, in another embodiment of this application, the input component 90 includes an input shaft 91, which extends along a direction parallel to the axis of the cleaning body 10. A first end of the input shaft 91 is connected to the end of the cleaning body 10 away from the drive end 102. The first gear component 31 includes a worm gear 312, which is disposed at a second end of the input shaft 91 opposite to the first end, and the axis of the worm gear 312 is parallel to the axis of the cleaning body 10. The second gear component 32 includes a worm wheel 323 and a plurality of transmission gears 324. The worm wheel 323 meshes with the worm 312 and the transmission gear 324 respectively, and the axis of the worm wheel 323 is perpendicular to the axis of the worm 312. Multiple transmission gears 324 are arranged and meshed in sequence along a direction parallel to the axis of the cleaning body 10, and the axes of the multiple transmission gears 324 are all parallel to the axis of the worm wheel 323. Among them, the transmission gear 324 closest to the first gear component 31 in the direction away from the worm wheel 323 meshes with the worm wheel 323, and the transmission gear 324 farthest from the first gear component 31 is connected to the crank slider assembly 40.
[0036] Specifically, in this embodiment, when the cleaning body 10 rotates around its own axis, the worm gear 323, multiple transmission gears 324, and crank-slider assembly 40 all rotate synchronously with the cleaning body 10. Because the worm gear 323 meshes with the worm 312, the worm gear 323, rotating with the cleaning body 10, will rotate under the action of the worm 312, thereby driving the transmission gear 324 meshing with it to rotate. This transmission gear 324 transmits power sequentially to the other transmission gears 324, enabling the entire second gear assembly 32 to rotate synchronously. Finally, the transmission gear 324 furthest from the worm gear 323 transmits the synchronously rotating power to the crank-slider assembly 40 connected to it, thus converting the rotational motion of the transmission gear 324 into the reciprocating motion of the cutting assembly 20 along a direction parallel to the axis of the cleaning body 10, thereby achieving the cutting of foreign objects.
[0037] Specifically, the worm gear 312 in this embodiment has a high transmission ratio. When the worm gear 312 meshes with the worm wheel 323, it can achieve a significant reduction in speed. The high reduction ratio requirement can be met without the need for additional multi-stage transition gears, thus reducing the overall number of transmission components. Simultaneously, this high transmission ratio design, combined with the meshing transmission of the worm wheel 323 and multiple transmission gears 324, not only further optimizes the speed reduction and torque increase effect while reducing the number of components, but also fully utilizes the space of the cavity 101 to achieve a neat and orderly structural arrangement, avoiding the cluttered distribution caused by component redundancy. Ultimately, the transmission gear 324, which is furthest from the first gear component 31 and connected to the crank-slider assembly 40, outputs a smooth and sufficient driving force with a more streamlined transmission structure, ensuring the efficient operation of subsequent actuators, while reducing structural complexity and assembly difficulty.
[0038] In other words, in this embodiment, the worm gear 312 is positioned on the input shaft 91, allowing direct input of the worm gear 312 for speed reduction and steering. This achieves a higher transmission ratio for speed reduction while simultaneously enabling steering. Furthermore, this embodiment uses the worm gear 312 in conjunction with the transmission gear 324 to achieve power transmission. This reduces the number of transmission components within the confined space of the cavity 101, achieving multi-ratio speed reduction, thus lowering costs. Additionally, the cutting torque of the cutting assembly 20 increases after being reduced by multiple transmission gears 324, effectively improving the cutting effect.
[0039] Exemplarily, the transmission gears 324 in this embodiment include two, three, or more; this application does not impose a specific limitation. This embodiment Figure 5 The diagram shows the case where the transmission gear 324 includes two gears.
[0040] Further, see Figures 3 to 4As shown, the crank-slider assembly 40 in this embodiment includes a slider body 41 and a crank body 42. The slider body 41 is disposed in the cavity 101 and can reciprocate along the axis parallel to the cleaning body 10; the first end of the crank body 42 is hinged to the second gear component 32, and the hinge position between the crank body 42 and the second gear component 32 is offset from the geometric center of the second gear component 32. The second end of the crank body 42, opposite to the first end, is hinged to the slider body 41. When the second gear component 32 rotates, it drives the crank body 42 to move, thereby driving the slider body 41 to reciprocate along the axis parallel to the cleaning body 10.
[0041] Specifically, in this embodiment, the slider body 41 can directly drive the cutting component 20 to move through its own reciprocating movement, ensuring the reliability and stability of the cutting component 20 in processing hair, long strip-shaped foreign objects, etc. Meanwhile, this embodiment, by setting the hinge position between the crank body 42 and the second gear component 32 off from the geometric center of the second gear component 32, eliminates the need for additional cams or eccentric wheel structures, naturally converting the rotational motion of the second gear component 32 into the oscillating power of the crank body 42, simplifying the component configuration of the power conversion process. Furthermore, since the second end of the crank body 42 is hinged to the slider body 41, the eccentric circular motion of the crank body 42 can be smoothly transitioned into the linear reciprocating motion of the slider body 41.
[0042] In this embodiment, when the second gear component 32 rotates under the drive of the cleaning body 10, the second gear component 32 drives the slider body 41 to reciprocate in a direction parallel to the axis of the cleaning body 10 through the eccentric transmission of the crank body 42, thereby driving the cutting component 20 to move synchronously to cut the hair wrapped around the cleaning body 10. The design of the entire crank-slider assembly 40 not only achieves the precise conversion of rotational power into linear motion through a simple mechanical structure, eliminating the need for complex electronic or hydraulic drive devices and reducing the number of parts and costs, but also ensures the stability and accuracy of the cutting action by utilizing the directional movement of the slider body 41 and the eccentric design of the crank body 42.
[0043] For example, in this embodiment, the hinge joint of the crank-slider assembly 40 is provided with an oil-impregnated bearing, which reduces manufacturing costs.
[0044] Further, see Figure 2As shown, in this embodiment, one of the slider body 41 and the cutting component 20 is provided with a snap-fit part 50, and the other is provided with a slot 60 that matches the snap-fit part 50. This simplifies the assembly process and ensures a stable connection while facilitating subsequent maintenance or replacement of components. When the cutting component 20 needs to be replaced due to wear from long-term use, it can be quickly disassembled simply by separating the snap-fit part 50 from the slot 60, without disassembling other transmission components inside the cleaning mechanism, significantly reducing maintenance difficulty and time costs.
[0045] Of course, in other embodiments of this application, the slider body 41 and the cutting component 20 can also be connected by screwing, magnetic attraction, welding or other means. Any other variations under the concept of this application are within the protection scope of this application.
[0046] It is understood that in this embodiment, the slider body 41 may have a locking portion 50, while the cutting assembly 20 may have a locking groove 60; alternatively, the slider body 41 may have a locking groove 60, while the cutting assembly 20 may have a locking portion 50. Figure 2 The diagram shows a case where the slider body 41 is provided with a snap-fit part 50 and the cutting assembly 20 is provided with a slot 60.
[0047] Further, see Figures 2 to 4 As shown, the cutting assembly 20 in this embodiment includes a first cutting element 21 and a second cutting element 22. The first cutting element 21 is disposed on the cleaning body 10 and extends along the axis parallel to the cleaning body 10, and a portion of the first cutting element 21 protrudes from the outer surface of the cleaning body 10; the second cutting element 22 is stacked with the first cutting element 21 and connected to the crank-slider assembly 40, so as to reciprocate along the axis parallel to the cleaning body 10 under the drive of the crank-slider assembly 40, and a portion of the second cutting element 22 protrudes from the outer surface of the cleaning body 10.
[0048] Specifically, in this embodiment, the rotation of the second gear component 32 drives the crank-slider assembly 40 to reciprocate along an axis parallel to the cleaning body 10, thereby driving the second cutting component 22 to reciprocate synchronously in that direction. This power transmission path relies entirely on the rotational power of the cleaning body 10, eliminating the need for a separate drive structure for the second cutting component 22. This maintains the simplicity of the overall mechanical transmission while ensuring precise coordination between the movement rhythm of the second cutting component 22 and the rotation of the cleaning body 10, as well as the static layout of the first cutting component 21. Simultaneously, since the second cutting component 22 and the first cutting component 21 are stacked and partially protrude from the outer surface of the cleaning body 10, during the reciprocating motion of the second cutting component 22, the portion of the second cutting component 22 protruding from the outer surface of the cleaning body 10 forms a dynamically intersecting cutting area with the protruding portion of the first cutting component 21. When foreign objects such as hair are entangled on the outer surface of the cleaning body 10, the reciprocating movement of the second cutting component 22 can quickly cut these foreign objects, effectively preventing them from becoming entangled on the surface of the cleaning body 10.
[0049] For example, in this embodiment, the extension length of the second cutting member 22 is less than the extension length of the first cutting member 21.
[0050] Optionally, see Figure 2 As shown, in this embodiment, the portion of the first cutting member 21 protruding from the outer surface of the cleaning body 10 has a plurality of first cutting teeth 211, and the portion of the second cutting member 22 protruding from the outer surface of the cleaning body 10 has a plurality of second cutting teeth 221. The plurality of first cutting teeth 211 and the plurality of second cutting teeth 221 are arranged sequentially along a direction parallel to the axis of the cleaning body 10.
[0051] It is understood that the shapes of the first cutting tooth 211 and the second cutting tooth 221 can be adjusted according to the actual situation. This application does not make specific limitations. As long as the first cutting tooth 211 and the second cutting tooth 221 can cut foreign objects such as hair, the deformation is within the protection scope of this embodiment.
[0052] Further, see Figure 1 and Figure 3 As shown, in this embodiment, the outer surface of the cleaning body 10 is provided with a plurality of comb teeth 70. The plurality of comb teeth 70 are spaced apart along the direction parallel to the axis of the cleaning body 10 and extend along the circumference of the cleaning body 10. The length of each comb tooth 70 protruding from the outer surface of the cleaning body 10 is greater than the length of the first cutting member 21 and the second cutting member 22 protruding from the outer surface of the cleaning body 10. Each comb tooth 70 has a clearance notch 80 for avoiding the first cutting member 21 and the second cutting member 22.
[0053] Specifically, in this embodiment, multiple comb teeth 70 are spaced apart along an axis parallel to the cleaning body 10. This allows the cleaning body 10 to comb and divert foreign objects such as hair and fibers encountered during rotation, concentrating them in the gap between adjacent comb teeth 70, facilitating cutting by the first cutting element 21 and the second cutting element 22. Simultaneously, because the length of the comb teeth 70 protruding from the outer surface of the cleaning body 10 is greater than the length of the first cutting element 21 and the second cutting element 22, when foreign objects such as hair are entangled on the cleaning body 10, the comb teeth 70 can preferentially contact the hair, thus pre-combing and organizing the messy hair and other foreign objects, creating conditions for the subsequent cutting actions of the first cutting element 21 and the second cutting element 22. The setting of the clearance notch 80 ensures that the comb tooth 70 and the first cutting part 21 and the second cutting part 22 can coexist reasonably on the outer surface of the cleaning body 10, avoiding structural interference between the two during movement, and also allows the first cutting part 21 and the second cutting part 22 to extend normally within the space of the clearance notch 80 and complete the cutting operation.
[0054] Specifically, in this embodiment, when the comb teeth 70 divert foreign objects such as hair to the space between the two comb teeth 70 or to the clearance notch 80, the second cutting component 22, driven by the crank-slider assembly 40, reciprocates along a direction parallel to the axis of the cleaning body 10, causing the portion protruding from the outer surface of the cleaning body 10 to cut the foreign objects such as hair, effectively ensuring the stability and reliability of foreign object handling. In other words, this embodiment, through the cooperation of the comb teeth 70 and the cutting component 20, can reduce the impact of foreign object entanglement on the rotation of the cleaning body 10, ensuring the long-term stable operation of the cleaning mechanism.
[0055] Further, see Figures 1 to 2 As shown, the comb tooth component 70 in this embodiment includes a first comb tooth segment 71 and a second comb tooth segment 72. The cleaning body 10 includes a first body 11 and a second body 12. The first comb tooth segment 71 is disposed on the outer surface of the first body 11, and the second comb tooth segment 72 is disposed on the outer surface of the second body 12 and surrounds the first comb tooth segment 71 to form an avoidance gap 80. The portion of the cutting component 20 protruding from the outer surface of the cleaning body 10 is located between the first comb tooth segment 71 and the second comb tooth segment 72.
[0056] Specifically, in this embodiment, the first comb tooth segment 71 is disposed on the outer surface of the first main body 11, and the second comb tooth segment 72 is disposed on the outer surface of the second main body 12. This arrangement allows the comb tooth component 70 to be spliced simultaneously when the first main body 11 and the second main body 12 are assembled together, eliminating the need for separate overall installation of the comb tooth component 70 and reducing the assembly difficulty of the outer surface components of the cleaning body 10. At the same time, the first comb tooth segment 71 and the second comb tooth segment 72 form an avoidance notch 80, allowing the forming of the avoidance notch 80 to be combined with the assembly process of the cleaning body 10, eliminating the need for additional notches to be processed on the complete comb tooth component 70 and simplifying the production process of the comb tooth component 70. Furthermore, since the portion of the cutting component 20 protruding from the outer surface of the cleaning body 10 in this embodiment is located between the first comb tooth segment 71 and the second comb tooth segment 72, when foreign objects such as hair are wrapped around the cleaning body 10, the first comb tooth segment 71 and the second comb tooth segment 72 comb the foreign objects such as hair into the gap between the two adjacent comb tooth segments 70, and then the portion of the cutting component 20 protruding from the outer surface of the cleaning body 10 cuts the hair, effectively preventing the hair and other foreign objects from getting tangled.
[0057] Furthermore, in this embodiment, the maximum diameter D of the cavity 101 satisfies the relationship: 12mm≤D≤20mm. For example, D can be set to 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, etc.
[0058] Specifically, this embodiment ensures that D satisfies the relationship: 12mm≤D≤20mm. This not only allows for a reasonable layout of transmission components such as the cleaning body 10, input shaft 91, gear assembly 30, and crank-slider assembly 40, reserving sufficient installation and movement space for each component, avoiding interference or assembly difficulties caused by an excessively small cavity 101, but also effectively controls the overall volume of the cavity 101. This ensures that while meeting internal transmission requirements, the overall space occupied by the equipment is not increased due to excessive size, making it particularly suitable for cleaning equipment scenarios that require miniaturization and lightweight design. When D is less than 12mm, the installation space for transmission components such as the cleaning body 10, input shaft 91, gear assembly 30, and crank-slider assembly 40 inside the cavity 101 will be excessively compressed. This may not only cause motion interference due to insufficient clearance between components, affecting the smoothness of gear meshing and the rotational flexibility of the input shaft 91, but also limit the reasonable size design of each component. When D is greater than 20mm, although it can provide more space for internal components, it will significantly increase the volume and weight of the cavity 101 itself, destroying the overall miniaturization and lightweight design of the equipment. It is especially unsuitable for cleaning scenarios with strict size restrictions. At the same time, the excessively large cavity 101 space will cause material waste and increase production and manufacturing costs.
[0059] Furthermore, in this embodiment, the transmission ratio i of the gear assembly 30 satisfies the relationship: 8≤i≤24. For example, i can be set to 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, etc.
[0060] Specifically, this embodiment ensures that the transmission ratio i of the gear assembly 30 satisfies the relationship: 8 ≤ i ≤ 24. This not only avoids insufficient rotational speed of the second gear component 32 and excessively low reciprocating frequency of the crank-slider assembly 40 driving the second cutting element 22 due to an excessively small transmission ratio, thus preventing the timely cutting of rapidly entangled hair, but also prevents excessively fast reciprocating speed of the second cutting element 22 due to an excessively large transmission ratio, increasing power loss, and even causing motion interference with the first cutting element 21. When the cleaning body 10 rotates at a normal speed, the lower limit of the transmission ratio of 8 ensures that the second cutting element 22 has sufficient reciprocating speed to deal with foreign objects that come into rapid contact with the cleaning equipment during its movement; the upper limit of the transmission ratio of 24 controls the movement amplitude of the second cutting element 22, preventing it from experiencing accelerated structural wear due to excessive speed.
[0061] Furthermore, in this embodiment, an input shaft 91 is provided inside the cavity 101. The rotational speed n of the input shaft 91 satisfies the relationship: 1000r / min≤n≤1400r / min. For example, n can be set to 1000r / min, 1050r / min, 1100r / min, 1150r / min, 1200r / min, 1250r / min, 1300r / min, 1350r / min, 1400r / min, etc.
[0062] Specifically, this embodiment ensures that the rotational speed n of the input shaft 91 satisfies the relationship: 1000r / min≤n≤1400r / min. This not only matches the power output characteristics of the cleaning body 10, ensuring that the power transmitted by the cleaning body 10 can be efficiently converted into the rotational speed required for subsequent transmission through the input shaft 91, avoiding insufficient power transmission efficiency due to excessively low speed, which would affect the rotational response speed of the second gear component 32 and thus slow down the movement rhythm of the crank-slider assembly 40; but also, through reasonable upper limit control of the rotational speed, prevents excessively high speed of the input shaft 91 from causing excessive impact load when the first bevel gear 311 meshes with the second gear component 32, reducing wear on the tooth surface of the second gear component 32 and extending the service life of the bevel gear set and multiple gears.
[0063] Further, see Figures 1 to 2 As shown, the cleaning body 10 in this embodiment includes a first body 11 and a second body 12. The first body 11 is detachably connected to the second body 12 and together with the second body 12 forms a cavity 101.
[0064] Specifically, the cavity 101 formed by the first body 11 and the second body 12 provides a stable installation and protective space for internal transmission components such as the input shaft 91, gear assembly 30, and crank-slider assembly 40, preventing external dust and impurities from entering and affecting the operation of the components, while ensuring the closed and safe transmission of power during the transmission process. The detachable connection of the first body 11 to the second body 12 does not affect the structural stability of the cavity 101, and allows for quick opening of the cavity 101 by disassembling the first body 11 when internal transmission components need to be inspected or replaced, without requiring the complete disassembly of the cleaning body 10, significantly reducing maintenance difficulty and time costs.
[0065] Further, see Figure 6 As shown, in this embodiment, the first end of the input component 90 protrudes from the cavity 101. The cleaning mechanism also includes a bearing component 100, which includes a bearing body 110 and a bearing cover 120. The bearing body 110 is sleeved on the first end of the input component 90, and the input component 90 is connected to the bearing cover 120 through the bearing body 110.
[0066] Specifically, in this embodiment, the first end of the input component 90 protrudes from the cavity 101, providing an installation base for the connection between the input shaft 91 and the bearing component 100. This allows the bearing body 110 in the bearing component 100 to be fitted onto the protruding end of the input shaft 91, ensuring coaxiality between the bearing body 110 and the input shaft 91. This prevents the bearing body 110 from shifting due to limited installation position, effectively ensuring that the bearing body 110 can stably provide support when the cleaning body 10 rotates relative to the input shaft 91. Simultaneously, when the cleaning mechanism of this application is installed on a cleaning device, the cleaning body 10 can be connected to the cleaning device through the bearing cover 120 to limit the movement of the cleaning mechanism, preventing displacement due to vibration or force during operation, and ensuring the stability and reliability of the transmission connection between the input component 90 and the gear assembly 30 within the cavity 101. Specifically, the bearing cover 120 is adapted to be installed and positioned at the end of the cleaning mechanism mounting cavity of the cleaning equipment, so that the cleaning body 10 can rotate relative to the bearing cover 120. That is, the cleaning body 10 is connected to the bearing cover 120 through the input component 90, and can rotate relative to the input component 90.
[0067] Based on the above, the working principle of the cleaning organization in this application is as follows: When the cleaning mechanism of this application is installed on a cleaning device, a predetermined drive structure such as a motor on the cleaning device is used to drive the cleaning body 10 to rotate around its own axis. During the rotation of the cleaning body 10, the second gear component 32 rotates synchronously with the cleaning body 10. At this time, since the first gear body 3211, which is closest to the first gear component 31, meshes with the first gear component 31, the first gear body 3211 will rotate around its own axis during the synchronous rotation with the cleaning body 10, thereby driving the second gear body 3212, which is coaxially arranged with the first gear body 3211, to rotate. This, in turn, drives the remaining gear set 321 to rotate synchronously, and further drives the crank body 42 in the crank-slider assembly 40 to rotate around the first gear body 3211, which is furthest from the first gear component 31, so as to drive the slider body 41 to reciprocate along the axis parallel to the cleaning body 10. Next, the second cutting element 22, which is connected to the slider body 41, reciprocates synchronously along the axis parallel to the cleaning body 10 to cut the foreign objects such as hair wrapped around the cleaning body 10.
[0068] On the other hand, this application also provides a cleaning device that includes the aforementioned cleaning mechanism, and therefore, the 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.
[0069] 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.
[0070] 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.
[0071] The above are merely preferred embodiments of this application and are not intended to limit 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.
