Description

Technical Field

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

[0002] Cleaning equipment includes robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment often uses cleaning devices to clean dust, debris, hair, and other debris from surfaces to be cleaned.

[0003] However, existing cleaning devices are difficult to adapt to different types of surfaces to be cleaned, resulting in poor cleaning results. Utility Model Content

[0004] The main objective of this application is to provide a cleaning device and equipment to solve the problem that existing cleaning devices are difficult to adapt to different types of surfaces to be cleaned, resulting in poor cleaning effects.

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

[0006] A housing assembly having a receiving cavity and an opening communicating with the receiving cavity;

[0007] A cleaning component, the cleaning component being rotatably disposed in the receiving cavity, and at least a portion of the cleaning component being located in the opening and cleaning the surface to be cleaned from the opening;

[0008] An adjustment component is movably disposed on the housing assembly, and the adjustment component has a first position away from the surface to be cleaned to fully expose the opening, and a second position close to the surface to be cleaned to cover at least part of the opening;

[0009] A drive mechanism is disposed on the housing assembly. The drive mechanism includes a first drive component and a second drive component. The first drive component is driven to the adjustment component to drive the adjustment component to switch between a first position and a second position. The second drive component is driven to the cleaning component to drive the cleaning component to rotate about its own axis.

[0010] Furthermore, the housing assembly includes a bottom shell and a cover plate. The bottom shell has the receiving cavity and the opening. The first driving assembly and the second driving assembly are both disposed on the bottom shell. The cover plate is detachably disposed on the bottom shell and surrounds the outer periphery of the opening. The adjusting assembly is movably connected to the cover plate.

[0011] Furthermore, the adjusting assembly includes an adjusting member rotatably disposed on the cover plate;

[0012] The cover plate is provided with a connector, the two ends of which are respectively connected to the first driving component and the adjusting component. Under the drive of the first driving component, the connector drives the adjusting component to rotate in a first rotation direction or a second rotation direction opposite to the first rotation direction, and switches between the first position and the second position.

[0013] Furthermore, the opening has a first side and a second side opposite to the first side. Along the height direction of the housing assembly, the distance from the first side to the bottom surface of the cleaning assembly is greater than the distance from the second side to the bottom surface of the cleaning assembly. The adjusting member is located on the first side, and an elastic member is provided between the adjusting member and the cover plate.

[0014] The elastic element has a compressed state and a natural state. When the connecting member drives the adjusting member to rotate along the first rotation direction or the second rotation direction and switch between the first position and the second position, the elastic element switches between the compressed state and the natural state. When the elastic element switches from the compressed state to the natural state, the adjusting member switches from the first position to the second position under the elastic recovery action of the elastic element and rotates towards the inside of the opening along the second rotation direction.

[0015] Furthermore, there is a gap between the adjusting member and the cover plate;

[0016] The elastic element includes a flexible sealing portion, a first end of which is connected to the cover plate, and a second end of which, opposite to the first end, is connected to the adjusting element. The flexible sealing portion extends along the axial direction of the cleaning assembly and seals the gap.

[0017] Furthermore, the cover plate is also provided with a guide and a slider, the slider is slidably disposed on the guide and drivenly connected to the first driving component, and the slider is provided with mounting holes;

[0018] The connector includes a connecting rope, the first end of which is located in the mounting hole and has a stop protrusion. The minimum cross-sectional area of ​​the stop protrusion is greater than the maximum cross-sectional area of ​​the mounting hole. The second end of the connecting rope is embedded in the mounting groove of the adjusting member through a fixing part. The connecting rope has a taut state and a slack state.

[0019] Specifically, when the slider, driven by the first driving component, causes the connecting rope to be in the taut state, the adjusting member rotates along the first rotation direction to switch from the second position to the first position, thereby causing the elastic member to switch from the natural state to the compressed state; when the slider, driven by the first driving component, causes the connecting rope to be in the slack state, the elastic member switches from the compressed state to the natural state, causing the adjusting member to rotate along the second rotation direction under the elastic recovery action of the elastic member, thereby switching from the first position to the second position.

[0020] Furthermore, the cover plate is provided with a mounting part, the mounting part has a mounting cavity, the guide member includes a guide rod, the guide rod and the slider are both disposed in the mounting cavity, and the guide rod extends along the axial direction of the cleaning component, and the slider is sleeved on the guide rod through a guide hole;

[0021] The first drive assembly includes a drive component and a transmission component. The drive component is disposed on the bottom shell and drivenly connected to the transmission component. The transmission component includes a pusher component, which is movably disposed on the drive component and contacts the slider. The pusher component can push the slider to slide on the guide rod under the driving action of the drive component, thereby causing the connecting rope to switch between the taut state and the slack state.

[0022] Furthermore, the driving component includes a first driving motor and a lead screw. The first driving motor is drivenly connected to the lead screw to drive the lead screw to rotate. The lead screw extends along the axial direction of the cleaning assembly. The pushing member is sleeved on the lead screw and reciprocates along the extension direction of the lead screw.

[0023] Specifically, when the pushing member moves along the extension direction of the lead screw toward the direction closer to the first drive motor, the connecting rope is in the taut state, causing the adjusting member to be in the first position. When the pushing member moves along the extension direction of the lead screw toward the direction away from the first drive motor, the connecting rope is in the slack state, causing the adjusting member to be in the second position under the elastic recovery action of the elastic member.

[0024] Furthermore, the bottom shell is also provided with two position detection elements, which are located on opposite sides of the transmission component along the axis of the cleaning assembly. The transmission component is provided with a trigger part for contacting the position detection elements.

[0025] On the other hand, this application also provides a cleaning device, which includes the cleaning apparatus described above.

[0026] In this application, the size of the opening affects the vacuum level between the surface to be cleaned and the receiving cavity. A larger opening results in weaker suction within the receiving cavity, lower cleaning efficiency, and difficulty for debris to enter the cavity. Conversely, a smaller opening results in stronger suction, higher cleaning efficiency, and easier extraction of debris. In other words, when cleaning different types of surfaces, adjusting the opening size is sufficient to achieve the required suction. Therefore, this application uses a first driving component to switch the adjusting component between a first and second position, thereby changing the opening size to adjust the cleaning efficiency. This allows the cleaning device to adaptively adjust the opening size according to the surface being cleaned, ensuring that debris on different surfaces can be extracted into the receiving cavity, effectively improving the applicability of the cleaning device and guaranteeing its cleaning effect.

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.

[0040] As mentioned in the background section, existing cleaning equipment often uses cleaning devices to remove dust, debris, hair, and other impurities from surfaces to be cleaned. However, existing cleaning devices are difficult to adapt to different types of surfaces, resulting in poor cleaning performance. To address this, the inventors of this application have designed a novel cleaning device that solves the problem of existing cleaning devices being unable to adapt to different types of surfaces, leading to poor cleaning results. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.

[0041] See Figures 1 to 6 As shown, this application provides a cleaning device, which includes a housing assembly 10, a cleaning assembly 20, an adjustment assembly 30, and a drive mechanism 40.

[0042] The housing assembly 10 has a receiving cavity 11 and an opening 12 communicating with the receiving cavity 11; the cleaning assembly 20 is rotatably disposed in the receiving cavity 11, and at least a portion of the cleaning assembly 20 is located in the opening 12 and cleans the surface to be cleaned from the opening 12; the adjusting assembly 30 is movably disposed in the housing assembly 10, and the adjusting assembly 30 has a first position away from the surface to be cleaned to fully expose the opening 12, and a second position close to the surface to be cleaned to cover at least a portion of the opening 12; the driving mechanism 40 is disposed in the housing assembly 10, and the driving mechanism 40 includes a first driving assembly 41 and a second driving assembly 42, the first driving assembly 41 being drivenly connected to the adjusting assembly 30 to drive the adjusting assembly 30 to switch between the first position and the second position, and the second driving assembly 42 being drivenly connected to the cleaning assembly 20 to drive the cleaning assembly 20 to rotate about its own axis.

[0043] For example, the cleaning component 20 in this embodiment can be a roller brush, or a roller and a mop. The surface to be cleaned can be the floor inside a building, or the surface of other objects that need to be cleaned, such as carpets, floors, walls, beds, windows, etc.

[0044] It is worth noting that when using the cleaning device of this application to clean floors and other surfaces in a building, the adjusting component 30 can be in the first position to prevent interference between the adjusting component 30 and the central sweeper on the cleaning device; when using the cleaning device of this application to clean soft floor surfaces such as carpets, the adjusting component 30 needs to be in the second position to effectively improve the dust removal rate of the cleaning device. (The appendix to this embodiment is missing from the original text.) Figure 2 A schematic diagram of the cleaning device in the first position is shown; (Attached) Figure 3 A schematic diagram of the cleaning device in the second position is shown.

[0045] In this embodiment, the receiving cavity 11 provides a stable and protected installation space for the cleaning component 20. When the cleaning device in this embodiment is installed on a cleaning device (such as a robot vacuum cleaner, robot mop, etc.), the cleaning component 20 can rotate to sweep away debris from the surface to be cleaned, thereby sweeping the debris into the receiving cavity 11 from the opening 12. However, when the cleaning device performs cleaning operations, it will come into contact with different types of surfaces to be cleaned, which will affect the cleaning efficiency.

[0046] Therefore, this embodiment provides a movable adjustment component 30 on the housing assembly 10, and adjusts the position of the adjustment component 30 by the first drive component 41 to adjust the size of the opening 12, thereby allowing the cleaning device to adapt to different surfaces to be cleaned. This is because the size of the opening 12 has a certain impact on the vacuum level between the surface to be cleaned and the receiving cavity 11. When the opening 12 is larger, the suction force in the receiving cavity 11 is smaller, and the cleaning efficiency of the cleaning device is lower, making it difficult for debris to enter the receiving cavity 11 from the opening 12. When the opening 12 is smaller, the suction force in the receiving cavity 11 is greater, the cleaning efficiency of the cleaning device is higher, and debris is more easily sucked into the receiving cavity 11. In other words, when different types of surfaces need to be cleaned, only the size of the opening 12 needs to be adjusted to obtain the required suction force. Based on this, in this embodiment, the first driving component 41 drives the adjusting component 30 to switch between the first position and the second position, thereby changing the size of the opening 12 to adjust the cleaning efficiency of the cleaning device. This allows the cleaning device to adaptively adjust the size of the opening 12 according to the different surfaces to be cleaned, ensuring that the garbage on different surfaces to be cleaned can be sucked into the receiving cavity 11, effectively improving the applicability of the cleaning device and the cleaning equipment, and ensuring the cleaning effect of the cleaning device and the cleaning equipment.

[0047] Furthermore, the drive mechanism 40 in this embodiment is divided into an independent first drive component 41 and a second drive component 42. These two drive components drive the adjustment component 30 and the cleaning component 20 respectively, each performing its own function. Compared with the traditional complex linkage transmission structure, the transmission logic is simplified, interference and wear between components are reduced, and the complexity of transmission is reduced. This not only makes the cleaning device operate more stably, but also facilitates fault diagnosis and maintenance.

[0048] Further, see Figure 1 As shown, the housing assembly 10 in this embodiment includes a bottom shell 13 and a cover plate 14. The bottom shell 13 has an accommodating cavity 11 and an opening 12. The first driving assembly 41 and the second driving assembly 42 are both disposed on the bottom shell 13. The cover plate 14 is detachably disposed on the bottom shell 13 and surrounds the outer periphery of the opening 12. The adjusting assembly 30 is movably connected to the cover plate 14.

[0049] Specifically, the base shell 13 provides stable support for the cleaning component 20 and the cover plate 14, while the cover plate 14 provides stable support for the adjustment component 30. Since the base shell 13 has a receiving cavity 11 and an opening 12, and the cover plate 14 surrounds the outer periphery of the opening 12, when the cleaning component 20 needs to be disassembled, only the cover plate 14 needs to be removed from the base shell 13. The structure is simple, and the operation is convenient and quick. At the same time, since the adjustment component 30 is mounted on the cover plate 14, this avoids complex assembly operations within a closed space, making the installation and adjustment process of the adjustment component 30 more efficient and greatly reducing assembly difficulty and time costs.

[0050] For example, see Figure 4 As shown, in this embodiment, one of the bottom shell 13 and the cover plate 14 is provided with a slot 131, and the other is provided with a buckle 143 that matches the slot 131. Thus, when the cover plate 14 needs to be disassembled, it is only necessary to separate the buckle 143 from the slot 131; the structure is simple and easy to disassemble. Of course, in another embodiment of this application, the bottom shell 13 and the cover plate 14 can also be connected by screws.

[0051] Further, see Figures 2 to 3 As shown, the adjustment component 30 in this embodiment includes an adjustment member 31, which is rotatably mounted on the cover plate 14. A connector 44 is provided on the cover plate 14, with both ends of the connector 44 connected to the first driving component 41 and the adjustment member 31, respectively. Driven by the first driving component 41, the connector 44 drives the adjustment member 31 to rotate along a first rotation direction or a second rotation direction opposite to the first rotation direction, switching between the first position and the second position. It should be noted that the "first rotation direction" in this embodiment refers to the... Figure 2 The direction indicated by the letter X in the middle; "second rotation direction" refers to the attached... Figure 3 The direction indicated by the letter Z.

[0052] Specifically, in this embodiment, the first drive assembly 41 drives the connecting member 44 to move, thereby causing the adjusting member 31 to rotate along a first rotation direction or a second rotation direction, switching between a first position and a second position. The adjusting member 31 switches between the first and second positions by rotation, which reduces space occupation compared to a linear movement structure, making the overall structure of the cleaning device more compact. At the same time, the rotational action allows the adjusting member 31 to achieve a smooth transition during switching, precisely controlling the exposure degree of the opening 12, better adapting to different types of surfaces to be cleaned, and effectively improving cleaning efficiency. The transmission method of the first drive assembly 41 and the connecting member 44 is simple in structure. By rationally designing the movement trajectory of the connecting member 44, the driving force of the first drive assembly 41 can be effectively amplified, achieving stable rotation of the adjusting member 31 with a smaller power input. Furthermore, this transmission structure has fewer parts, lower assembly difficulty, reduces failure points caused by too many parts, and extends the service life of the cleaning device.

[0053] Furthermore, in this embodiment, one of the adjusting member 31 and the cover plate 14 is provided with a rotating shaft, and the other of the two is provided with a mounting hole adapted to the rotating shaft, the rotating shaft being rotatably disposed in the mounting hole. In this way, the adjusting member 31 can be rotated along a first rotation direction or a second rotation direction under the drive of the connecting member 44.

[0054] It is understood that in this embodiment, the adjusting member 31 may be provided with a rotating shaft and the cover plate 14 may be provided with a mounting hole, or the adjusting member 31 may be provided with a mounting hole and the cover plate 14 may be provided with a rotating shaft.

[0055] Further, see Figure 2 As shown, in this embodiment, the opening 12 has a first side 121 and a second side 122 opposite to the first side 121. Along the height direction of the housing assembly 10, the distance from the first side 121 to the bottom surface of the cleaning assembly 20 is greater than the distance from the second side 122 to the bottom surface of the cleaning assembly 20. The adjusting member 31 is located on the first side 121, and an elastic member 50 is provided between the adjusting member 31 and the cover plate 14. The elastic member 50 has a compressed state and a relaxed state. When the connecting member 44 drives the adjusting member 31 to rotate along a first rotation direction or a second rotation direction, switching between the first position and the second position, the elastic member 50 switches between the compressed state and the relaxed state. When the elastic member 50 switches from the compressed state to the relaxed state, the adjusting member 31, under the elastic recovery action of the elastic member 50, switches from the first position to the second position and rotates towards the inside of the opening 12 along the second rotation direction. It should be noted that the "height direction of the housing assembly 10" in this embodiment refers to the attached... Figure 2 The direction indicated by the letter Y; in this embodiment, the "natural state of elastic element 50" refers to the state in which elastic element 50 is neither stretched nor compressed.

[0056] Specifically, in this embodiment, since the distance from the first side 121 of the opening 12 to the bottom surface of the cleaning component 20 is greater than the distance from the second side 122 to the bottom surface of the cleaning component 20, when the cleaning device cleans the garbage on the surface to be cleaned, the opening 12 is opposite to the surface to be cleaned. At this time, the distance from the first side 121 to the surface to be cleaned is greater than the distance from the second side 122 to the surface to be cleaned. In this way, it can be ensured that as much garbage as possible can enter the receiving cavity 11 through the opening 12, effectively improving the cleaning effect of the cleaning device. At the same time, in this embodiment, by providing an elastic element 50 between the adjusting member 31 and the cover plate 14, it can not only play a buffering and protective role, avoiding wear caused by the collision between the adjusting member 31 and the cover plate 14, but also convert the elastic potential energy into the rotational potential energy of the adjusting member 31, thereby quickly realizing the adjustment of the size of the opening 12.

[0057] Further, see Figure 2 As shown, there is a gap between the adjusting member 31 and the cover plate 14; the elastic member 50 includes a flexible sealing part 53, the first end of the flexible sealing part 53 is connected to the cover plate 14, the second end of the flexible sealing part 53 opposite to the first end is connected to the adjusting member 31, and the flexible sealing part 53 extends along the axial direction of the cleaning assembly 20 and seals the gap.

[0058] Specifically, the flexible sealing part 53 provides room for the adjustment component 31 to move, allowing it to flexibly adjust its position to adapt to different working conditions and ensure the accuracy of the cleaning component 20's operation. Furthermore, because the flexible sealing part 53 extends along the axis of the cleaning component 20 and seals the gap, it prevents dust or debris from leaking out during operation. At the same time, the flexible sealing part 53 is also elastic, acting as a buffer and shock absorber between the adjustment component 31 and the cover plate 14, reducing noise and vibration during equipment operation, optimizing operational stability and reliability, and providing strong support for the efficient and stable operation of the equipment.

[0059] For example, the flexible sealing part in this embodiment includes flexible adhesive strips or flexible silicone, etc. Any other variation of the concept of this application is within the protection scope of this application.

[0060] Further, see Figure 3 As shown, the elastic element 50 in this embodiment includes a first elastic segment 51 and a second elastic segment 52. Both the first elastic segment 51 and the second elastic segment 52 extend along the axial direction of the cleaning component 20. The first elastic segment 51 is connected to the cover plate 14, and the second elastic segment 52 is connected to the adjusting member 31. When the elastic element 50 is in its natural state, the first elastic segment 51 and the second elastic segment 52 are arranged in a V-shape, and the open end of the V-shape is facing away from the opening 12.

[0061] Specifically, in this embodiment, the first elastic segment 51 and the second elastic segment 52 provide stable mechanical support for the adjusting member 31, ensuring that the adjusting member 31 is evenly stressed when subjected to external force, avoiding jamming or displacement caused by unilateral deformation, and ensuring more stable and reliable adjustment of the opening 12. When the adjusting member 31 switches from the second position to the first position, the V-shaped elastic member 50 gradually closes, and the first elastic segment 51 and the second elastic segment 52 deform together, providing progressive buffering, which can absorb impact force and avoid rigid collision, effectively protecting the adjusting member 31 and the housing assembly 10. In addition, by setting the V-shaped opening end away from the opening 12, this embodiment allows the elastic member 50 to have a directional recovery tendency after being compressed. When the external force acting on the elastic member 50 disappears, the elastic segment quickly rebounds due to its own deformation energy, driving the adjusting member 31 to reset, ensuring that the opening 12 always maintains the optimal ground clearance without manual intervention. In addition, the first elastic segment 51 and the second elastic segment 52 can share the stress, making them more fatigue-resistant than a single elastic element 50. They can maintain their elastic properties after long-term use, reducing the risk of failure due to plastic deformation and improving overall reliability.

[0062] Further, see Figures 2 to 3 As shown, in this embodiment, the second elastic segment 52 is connected to one end of the adjusting member 31, and a insertion groove 311 is provided on one of the adjusting members 31. The other end of the adjusting member 31 is provided with an insertion segment 521 adapted to the insertion groove 311, and the insertion segment 521 is embedded within the insertion groove 311. Of course, in other embodiments of this application, the second elastic segment 52 can also be connected to one end of the adjusting member 31 by screwing, welding, or other methods. Any other modifications within the scope of this application are within the protection range of this application.

[0063] It is understood that in this embodiment, the second elastic segment 52 may have a plug-in segment 521 at one end connected to the adjusting member 31, and the adjusting member 31 may have a plug-in groove 311; alternatively, the second elastic segment 52 may have a plug-in groove 311 at one end connected to the adjusting member 31, and the adjusting member 31 may have a plug-in segment 521. (The appendix of this embodiment is missing.) Figure 2 The diagram shows the case where the second elastic segment 52 is connected to one end of the adjusting member 31 and is provided with a plug-in segment 521, and the adjusting member 31 is provided with a plug-in groove 311.

[0064] Specifically, the engagement of the plug segment 521 and the plug slot 311 allows for rapid assembly of the elastic element 50 and the adjusting element 31 without the need for additional fasteners, thus shortening assembly time and reducing production costs. Simultaneously, the tight fit between the plug segment 521 and the plug slot 311 provides reliable mechanical connection strength, ensuring the stable transmission of the force generated by the elastic element 50 during compression and rebound to the adjusting element 31. This prevents abnormal shaking or adjustment failure of the adjusting element 31 due to loosening, guaranteeing the accuracy and continuity of cleaning operations. Furthermore, this design significantly improves maintenance convenience. When the elastic element 50 is damaged or its performance deteriorates, the plug segment 521 can be directly pulled out of the plug slot 311 for quick replacement of the elastic element 50 without disassembling the entire adjusting assembly 30, significantly reducing maintenance complexity and costs.

[0065] For example, in this embodiment, the first elastic segment 51 and the cover plate 14 can be connected by means of screwing, welding or snap-fitting. Any other variation of the concept under this application is within the protection scope of this application.

[0066] Further, see Figure 6 As shown, in this embodiment, the adjusting member 31 is provided with a through hole 312 for the connecting member 44 to pass through, and the second elastic segment 52 is provided with a clearance notch 522, the clearance notch 522 being positioned corresponding to the through hole 312.

[0067] Specifically, the through hole 312 provides a precise path for the connector 44 to pass through, ensuring a stable connection between the connector 44 and the adjusting member 31. This allows the power of the first drive assembly 41 to be reliably transmitted to the adjusting member 31, ensuring stable switching between the first and second positions. Meanwhile, the clearance notch 522 on the second elastic segment 52, corresponding to the through hole 312, provides space for the movement of the connector 44, preventing interference between the elastic member 50 and the connector 44 during compression and rebound. This ensures the normal functioning of both the elastic member 50 and the connector 44, effectively improving the smoothness and reliability of the adjusting assembly 30's operation.

[0068] Further, see Figure 4 , Figure 5 and Figure 7As shown, a guide member 45 and a slider 4332 are further provided on the cover plate 14 in this embodiment. The slider 4332 is slidably disposed on the guide member 45 and is drivingly connected to the first driving component 41. An installation hole (not shown in the drawings) is provided on the slider 4332. The connecting member 44 includes a connecting rope 441. The first end of the connecting rope 441 is located in the installation hole, and a stop projection (not shown in the drawings) is provided at the first end of the connecting rope 441. The minimum cross-sectional area of the stop projection is larger than the maximum cross-sectional area of the installation hole. The second end of the connecting rope 441 is embedded in the installation groove 313 of the adjusting member 31 through the fixing portion 442. The connecting rope 441 has a taut state and a slack state. Among them, when the slider 4332 drives the connecting rope 441 to be in the taut state under the driving of the first driving component 41, the adjusting member 31 rotates along the first rotation direction to switch from the second position to the first position, so that the elastic member 50 switches from the natural state to the compressed state. When the slider 4332 drives the connecting rope 441 to be in the slack state under the driving of the first driving component 41, the elastic member 50 switches from the compressed state to the natural state, so that the adjusting member 31 rotates along the second rotation direction under the elastic restoring force of the elastic member 50 and switches from the first position to the second position.

[0069] Specifically, in this application, the connecting rope 441 is used as the transmission medium. Compared with the traditional rigid connecting rod, the flexibility of the connecting rope 441 makes the internal space layout of the cleaning device more flexible, and can realize the power transmission of complex paths in a limited space. The connecting rope 441 can be switched between the taut state and the slack state under the driving of the first driving component 41 by the slider 4332, thereby converting the movement of the first driving component 41 into the state conversion of the connecting rope 441, and further realizing the linkage control of the position of the adjusting member 31 and the state of the elastic member 50. Among them, when the connecting rope 441 is taut, the adjusting member 31 is driven to rotate along the first rotation direction by the pulling force, so as to promote the elastic member 50 to change from the natural state to the compressed state, so as to efficiently transmit the power of the first driving component 41 to the adjusting member 31. When the connecting rope 441 is slack, the elastic member 50 pushes the adjusting member 31 to rotate reversely and reset by its own elastic restoring force, forming a closed-loop control. The overall structure is simple, without a complex mechanical transmission structure, reducing the manufacturing cost, and realizing a flexible and stable reciprocating adjustment function.

[0070] Meanwhile, the combination of guide 45 and slider 4332 provides a precise track for the movement of slider 4332, ensuring transmission stability, preventing wear of connecting rope 441 due to shaking, and extending its service life. The mounting hole on slider 4332 cooperates with the stop protrusion of connecting rope 441. The design of the stop protrusion having a cross-sectional area larger than the mounting hole ensures that connecting rope 441 will not come out of the mounting hole, achieving a stable connection. The second end of connecting rope 441 is embedded in the mounting groove 313 of adjusting member 31 through fixing part 442, which facilitates quick installation and removal of connecting rope 441 and adjusting member 31. This design combines connection stability and movement flexibility, not only ensuring that connecting rope 441 can reliably transmit power and displacement when slider 4332 moves on guide 45, but also allowing the position or tension of connecting rope 441 to be adjusted through adjusting member 31, thereby improving the reliability and adjustability of the entire device.

[0071] Further, see Figures 4 to 5 As shown, in this embodiment, the cover plate 14 is provided with a mounting part 141, the mounting part 141 has a mounting cavity 142, the guide member 45 includes a guide rod 451, the guide rod 451 and the slider 4332 are both disposed in the mounting cavity 142, and the guide rod 451 extends along the axial direction of the cleaning component 20, the slider 4332 is sleeved on the guide rod 451 through a guide hole (not shown in the figure); the first drive component 41 includes a drive component 43 and a transmission component 433, the drive component 43 is disposed on the bottom shell 13 and is drivenly connected to the transmission component 433, the transmission component 433 includes a pusher 4331, the pusher 4331 is movably disposed on the drive component 43 and contacts the slider 4332, the pusher 4331 can push the slider 4332 to slide on the guide rod 451 under the driving action of the drive component 43, thereby driving the connecting rope 441 to switch between a taut state and a slack state.

[0072] Specifically, the mounting cavity 142 integrates the guide rod 451 and the slider 4332 within the cover plate 14 structure, achieving compact integration of components, effectively saving external space and avoiding the risk of interference or damage caused by exposed parts. The guide rod 451 extends along the axis of the cleaning component 20 and mates with the guide hole of the slider 4332 to form a stable linear motion track, ensuring accurate positioning and smooth sliding of the slider 4332 during operation, reducing friction loss and motion deviation, thereby improving the reliability of the transmission system of the connecting rope 441. At the same time, this enclosed installation method can effectively isolate dust, debris and other impurities, reduce the corrosion of internal transmission components by the external environment, extend the service life of the equipment, and facilitate maintenance and repair.

[0073] Furthermore, the driving force is precisely transmitted to the slider 4332 via the pusher 4331, causing the slider 4332 to slide on the guide rod 451, thereby controlling the flexible switching of the connecting rope 441 between a taut and slack state. This design makes the entire system compact and highly efficient, achieving precise control over the state of the connecting rope 441 while facilitating installation and maintenance through modular design, thus improving the reliability and practicality of the equipment.

[0074] Further, see Figures 4 to 5 As shown, the driving component 43 in this embodiment includes a first driving motor 431 and a lead screw 432. The first driving motor 431 is driven to drive the lead screw 432 to rotate. The lead screw 432 extends along the axial direction of the cleaning component 20. The pushing member 4331 is sleeved on the lead screw 432 and reciprocates along the extension direction of the lead screw 432. When the pushing member 4331 moves along the extension direction of the lead screw 432 toward the direction closer to the first driving motor 431, the connecting rope 441 is in a taut state, so that the adjusting member 31 is in a first position. When the pushing member 4331 moves along the extension direction of the lead screw 432 toward the direction away from the first driving motor 431, the connecting rope 441 is in a slack state, so that the adjusting member 31 is in a second position under the elastic recovery action of the elastic member 50.

[0075] Specifically, the first drive motor 431 is driven by the lead screw 432, which efficiently converts the rotational power of the motor into the rotation of the lead screw 432, providing a stable and reliable power source for the system. The lead screw 432 extends along the axis of the cleaning component 20, and combined with the reciprocating motion characteristics of the pusher 4331 on the lead screw 432, the rotational motion of the lead screw 432 can be precisely converted into linear motion, achieving precise control of the state of the connecting rope 441. When the pusher 4331 moves towards the first drive motor 431, it can stably tighten the connecting rope 441, thereby driving the adjusting component 31 to switch to the first position and simultaneously allowing the elastic component 50 to store energy. When the pusher 4331 moves in the opposite direction, it can precisely release the tension of the connecting rope 441, allowing the elastic component 50 to push the adjusting component 31 back to its original position. This structure not only has high transmission efficiency and strong motion stability, but also allows for precise adjustment of the action of the adjusting component 31 by controlling the speed and direction of the lead screw 432, meeting the needs of different working conditions. Meanwhile, the modular design facilitates the installation, maintenance, and replacement of components, reducing equipment maintenance costs and improving the overall system reliability and service life.

[0076] In other words, in this embodiment, the first drive motor 431 drives the lead screw 432 to rotate, thereby driving the pusher 4331 to move back and forth on the lead screw 432 along the axis of the cleaning component 20, which in turn drives the connecting rope 441 to switch between a taut state and a slack state, and further drives the adjusting member 31 to switch between a first position and a second position, ultimately achieving the adjustment of the size of the opening 12.

[0077] Specifically, see Figures 4 to 5 As shown, in this embodiment, the pusher 4331 has two force-applying sections 47, both of which protrude from the side of the pusher 4331 near the slider 4332. The two force-applying sections 47 are spaced apart along the axial direction of the cleaning assembly 20. The slider 4332 has a force-receiving section 48 located between the two force-applying sections 47, with a gap between the force-receiving section 48 and the two force-applying sections 47. Thus, when the pusher 4331 reciprocates along the extension direction of the lead screw 432, the force-receiving section 48 can move under the pushing action of the two force-applying sections 47, causing the slider 4332 to slide on the guide rod 451, thereby switching the connecting rope 441 between a taut and slack state. Simultaneously, because there is a gap between the force-receiving section 48 and the two force-applying sections 47 in this embodiment, transmission errors can be accommodated.

[0078] Further, see Figures 4 to 5 As shown, in this embodiment, the bottom shell 13 is also provided with two position detection elements 60. The two position detection elements 60 are respectively located on opposite sides of the transmission component 433 along the axis of the cleaning component 20. The transmission component 433 is provided with a trigger part 46 for contacting the position detection elements 60.

[0079] Specifically, in this embodiment, two position detection elements 60 are positioned on opposite sides of the transmission component 433. This allows for accurate detection of the movement position of the transmission component 433. As the transmission component 433 moves along the axis of the cleaning assembly 20, the trigger part 46 moves with it. When it contacts the position detection element 60, the element immediately sends a signal to stop the first drive motor 431 or change its rotation direction, ensuring that the adjusting component 31 accurately switches to the first or second position, greatly improving the accuracy of cleaning mode switching. Simultaneously, the two position detection elements 60 prevent mechanical damage to the transmission component 433 due to excessive movement, preventing malfunctions such as breakage of the connecting rope 441 or jamming of the lead screw 432, effectively improving the stability and reliability of the cleaning device.

[0080] For example, the position detection element 60 in this embodiment includes a photoelectric sensor, a limit switch, or a Hall sensor, etc.

[0081] Further, see Figure 1 As shown, the second drive assembly 42 in this embodiment includes a second drive motor 421 and a gearbox 422. The gearbox 422 is connected to the cleaning assembly 20. The second drive motor 421 is driven to drive the gear set inside the gearbox 422 to rotate, thereby driving the cleaning assembly 20 to rotate around its own axis.
