[0014] In which, the elastic member 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 switches between the first position and the second position, the elastic member switches between the compressed state and the natural state, and when the elastic member 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 member and rotates along the second rotation direction toward the inner side of the opening.

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

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

[0019] Among them, when the slider drives the connecting rope to be in the taut state under the driving action of the first driving component, the adjusting member rotates along the first rotation direction to switch from the second position to the first position, and the elastic member switches from the natural state to the compressed state; when the slider drives the connecting rope to be in the relaxed state under the driving action of the first driving component, the elastic member switches from the compressed state to the natural state so that the adjusting member rotates along the second rotation direction under the elastic recovery action of the elastic member and switches from the first position to the second position.

[0025] On the other hand, the present application also provides a cleaning device, which includes the above-mentioned cleaning apparatus.

[0026] In the present application, since the size of the opening will have a certain impact on the vacuum degree between the surface to be cleaned and the accommodating chamber, when the size of the opening is larger, the suction force in the accommodating chamber is smaller, and the cleaning efficiency of the cleaning device is lower, which makes it difficult for garbage to enter the accommodating chamber from the opening; when the size of the opening is smaller, the suction force of the accommodating chamber is greater, the cleaning efficiency of the cleaning device is higher, and the garbage is easier to be sucked into the accommodating chamber. In other words, when it is necessary to clean different types of surfaces to be cleaned, it is only necessary to adjust the size of the opening to obtain the required suction force. Based on this, the present application drives the adjustment component to switch between the first position and the second position through the first drive component, so that the size of the opening can be changed to adjust the cleaning efficiency of the cleaning device, and then the cleaning device can adaptively adjust the size of the opening according to the different surfaces to be cleaned, ensuring that garbage on different surfaces to be cleaned can be sucked into the accommodating chamber, 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.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0040] As mentioned in the background, existing cleaning equipment often utilizes a cleaning device to remove debris, such as dust, debris, or hair, from a surface to be cleaned. However, existing cleaning devices are difficult to adapt to different types of surfaces to be cleaned, resulting in poor cleaning performance. To address this issue, the inventors of this application have designed a novel cleaning device that addresses the problem of existing cleaning devices being difficult to adapt to different types of surfaces to be cleaned, resulting in poor cleaning performance. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.

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

[0042] Among them, the shell assembly 10 has a accommodating cavity 11 and an opening 12 connected to the accommodating cavity 11; the cleaning assembly 20 is rotatably arranged in the accommodating cavity 11, and at least part 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 arranged in the shell assembly 10, and the adjusting assembly 30 has a first position away from the surface to be cleaned to completely expose the opening 12, and a second position close to the surface to be cleaned to cover at least part of the opening 12; the driving mechanism 40 is arranged in the shell assembly 10, and the driving mechanism 40 includes a first driving assembly 41 and a second driving assembly 42, the first driving assembly 41 is driven and 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 is driven and connected to the cleaning assembly 20 to drive the cleaning assembly 20 to rotate around its own axis.

[0043] For example, the cleaning assembly 20 in this embodiment can be a roller brush, or a roller and a mop. The surface to be cleaned can be the ground in 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 the cleaning device of the present application is used to clean the ground and floor in a building, the adjustment component 30 can be in the first position to prevent the adjustment component 30 from interfering with the middle sweep of the cleaning device; when the cleaning device of the present application is used to clean a soft ground environment such as a carpet, the adjustment component 30 needs to be in the second position to effectively improve the dust removal rate of the cleaning device. Figure 2 Shows a schematic structural diagram of the cleaning device in the first position; Figure 3 A schematic structural diagram of the cleaning device in the second position is shown.

[0045] In this embodiment, the accommodating chamber 11 can provide a stable and protected installation space for the cleaning assembly 20. When the cleaning device of this embodiment is installed on a cleaning device (such as a sweeping robot or a mopping robot), the cleaning assembly 20 can rotate to clean garbage on the surface to be cleaned, thereby sweeping the garbage into the accommodating chamber 11 through the opening 12. However, when the cleaning device performs a cleaning operation, the cleaning device may come into contact with different types of surfaces to be cleaned, thereby affecting cleaning efficiency.

[0046] To this end, this embodiment provides a movable adjustment assembly 30 on the housing assembly 10, and adjusts the position of the adjustment assembly 30 via the first drive assembly 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 will have a certain impact on the vacuum level between the surface to be cleaned and the accommodating chamber 11. When the size of the opening 12 is larger, the suction force within the accommodating chamber 11 is smaller, and the cleaning efficiency of the cleaning device is lower, making it difficult for garbage to enter the accommodating chamber 11 through the opening 12. When the size of the opening 12 is smaller, the suction force within the accommodating chamber 11 is greater, the cleaning efficiency of the cleaning device is higher, and garbage is more easily sucked into the accommodating chamber 11. In other words, when it is necessary to clean different types of surfaces to be cleaned, it is only necessary to adjust the size of the opening 12 to obtain the required suction force. Based on this, this embodiment drives the adjustment component 30 to switch between the first position and the second position through the first drive component 41, so that the size of the opening 12 can be changed to adjust the cleaning efficiency of the cleaning device, and then the cleaning device can 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 accommodating 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] In addition, the driving mechanism 40 in this embodiment is divided into an independent first driving component 41 and a second driving component 42. These two driving 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, it simplifies the transmission logic, reduces interference and wear between components, and reduces the complexity of the transmission, which not only makes the cleaning device run more stably, but also facilitates troubleshooting and maintenance.

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

[0049] Specifically, the bottom shell 13 provides stable support for the cleaning assembly 20 and the cover plate 14, while the cover plate 14 provides stable support for the adjustment assembly 30. Because the bottom shell 13 is provided with a receiving cavity 11 and an opening 12, and the cover plate 14 is arranged around the periphery of the opening 12, when the cleaning assembly 20 needs to be disassembled, it is only necessary to remove the cover plate 14 from the bottom shell 13. This simple structure makes operation convenient and quick. Furthermore, because the adjustment assembly 30 is mounted on the cover plate 14, complex assembly operations in an enclosed space are avoided, making the installation and commissioning of the adjustment assembly 30 more efficient and significantly reducing the difficulty and time cost of assembly.

[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 removed, it is only necessary to separate the buckle 143 from the slot 131. This simplifies the structure and facilitates disassembly. Of course, in another embodiment of the present application, the bottom shell 13 and the cover plate 14 can also be connected by screwing.

[0051] Further, see Figures 2 to 3 As shown, the adjustment assembly 30 in this embodiment includes an adjustment member 31, which is rotatably arranged on the cover plate 14; a connecting member 44 is provided on the cover plate 14, and the two ends of the connecting member 44 are respectively connected to the first driving assembly 41 and the adjustment member 31. Under the drive of the first driving assembly 41, the connecting member 44 drives the adjustment member 31 to rotate along the first rotation direction or the second rotation direction opposite to the first rotation direction, and switches between the first position and the second position. It should be noted that the "first rotation direction" in this embodiment refers to the second rotation direction of the first position. Figure 2 The direction indicated by the letter X in the figure; the “second rotation direction” refers to the direction indicated by the letter X in the figure. 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 driving the adjusting member 31 to rotate along the first rotation direction or the second rotation direction and switch between the first position and the second position. The adjusting member 31 switches between the first position and the second position in a rotational manner. Compared with the linear moving structure, it reduces the space occupied and makes the overall structure of the cleaning device more compact. At the same time, the rotation action can enable the adjusting member 31 to achieve a smooth transition during the switching process, accurately control the exposure degree of the opening 12, better adapt to different types of floors to be cleaned, and effectively improve the cleaning efficiency. The transmission method of the first drive assembly 41 in conjunction with the connecting member 44 is simple in structure. By rationally designing the motion trajectory of the connecting member 44, the driving force of the first drive assembly 41 can be effectively amplified, and the stable rotation of the adjusting member 31 can be achieved with a smaller power input. In addition, this transmission structure has fewer parts and is easy to assemble, which reduces the failure points caused by too many parts and extends the service life of the cleaning device.

[0053] Furthermore, in this embodiment, a rotating shaft is provided on one of the adjusting member 31 and the cover plate 14, and a mounting hole adapted for the rotating shaft is provided on the other of the adjusting member 31 and the cover plate 14. The rotating shaft is rotatably disposed in the mounting hole. In this manner, the adjusting member 31 can be driven by the connecting member 44 to rotate in the first rotation direction or the second rotation direction.

[0054] It is understandable 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, the opening 12 in this embodiment has a first side 121 and a second side 122 opposite to the first side 121. Along the height direction of the shell 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; wherein, the elastic member 50 has a compressed state and a natural state. When the connecting member 44 drives the adjusting member 31 to rotate along the first rotation direction or the second rotation direction and switches between the first position and the second position, the elastic member 50 switches between the compressed state and the natural state, and when the elastic member 50 switches from the compressed state to the natural state, the adjusting member 31 switches from the first position to the second position under the elastic recovery action of the elastic member 50 and rotates toward the inner side of the opening 12 along the second rotation direction. It should be noted that the "height direction of the shell assembly 10" in this embodiment refers to the height direction of the shell assembly 10. Figure 2 The direction indicated by the letter Y in the figure; the "natural state of the elastic member 50" in this embodiment refers to a state in which the elastic member 50 is neither stretched nor compressed.

[0056] Specifically, since the distance from the first side 121 of the opening 12 to the bottom surface of the cleaning assembly 20 in this embodiment is greater than the distance from the second side 122 to the bottom surface of the cleaning assembly 20, when the cleaning device uses the cleaning device to clean 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 accommodating chamber 11 through the opening 12, effectively improving the cleaning effect of the cleaning device. At the same time, this embodiment provides an elastic member 50 between the adjusting member 31 and the cover plate 14, which not only plays a buffering and protective role to avoid wear caused by collision between the adjusting member 31 and the cover plate 14, but also converts elastic potential energy into rotational potential energy of the adjusting member 31, thereby quickly adjusting 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 portion 53, a first end of the flexible sealing portion 53 is connected to the cover plate 14, a second end of the flexible sealing portion 53 opposite to the first end is connected to the adjusting member 31, and the flexible sealing portion 53 extends along the axial direction of the cleaning component 20 and seals in the gap.

[0058] Specifically, the flexible sealing portion 53 provides space for the adjustment member 31 to maneuver, allowing it to flexibly adjust its position to suit different operating conditions and ensure the precise operation of the cleaning assembly 20. Furthermore, because the flexible sealing portion 53 extends along the axis of the cleaning assembly 20 and seals the gap, it prevents dust and debris from escaping through the gap while the cleaning assembly 20 is operating. Furthermore, the flexible sealing portion 53's elasticity provides a buffering and shock-absorbing effect between the adjustment member 31 and the cover plate 14, reducing noise and vibration during operation, optimizing operational stability and reliability, and providing a strong guarantee for the efficient and stable operation of the equipment.

[0059] Illustratively, the flexible sealing portion in this embodiment includes a flexible rubber strip or flexible silicone, etc. As long as it is other deformation methods based on the concept of this application, it is within the scope of protection of this application.

[0060] Further, see Figure 3 As shown, the elastic member 50 in this embodiment includes a first elastic section 51 and a second elastic section 52, both of which extend along the axial direction of the cleaning component 20, and the first elastic section 51 is connected to the cover plate 14, and the second elastic section 52 is connected to the adjusting member 31; wherein, when the elastic member 50 is in a natural state, the first elastic section 51 and the second elastic section 52 are arranged in a V-shape, and the open end of the V-shape is arranged away from the outlet 12.

[0061] Specifically, the arrangement of the first elastic segment 51 and the second elastic segment 52 in this embodiment provides stable mechanical support for the adjusting member 31, ensuring that the adjusting member 31 is evenly stressed when subjected to external forces, avoiding stagnation or offset caused by unilateral deformation, and ensuring smoother and more 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 cooperatively deform, providing progressive cushioning that absorbs impact forces while preventing rigid collisions, effectively protecting the adjusting member 31 and the housing assembly 10. Furthermore, by positioning the V-shaped opening away from the opening 12, this embodiment allows the elastic member 50 to exhibit a directional recovery tendency after being subjected to pressure. When the external force acting on the elastic member 50 disappears, the elastic segment rapidly rebounds due to its own deformation, driving the adjusting member 31 back to its original position, ensuring that the opening 12 always maintains optimal ground clearance without the need for manual intervention. In addition, the arrangement of the first elastic section 51 and the second elastic section 52 can share stress, is more fatigue-resistant than a single elastic member 50, can still maintain elastic properties after long-term use, reduces the risk of failure due to plastic deformation, and improves overall reliability.

[0062] Further, see Figures 2 to 3 As shown, in this embodiment, the second elastic section 52 is connected to one end of the adjusting member 31, and one of the adjusting member 31 is provided with an inserting groove 311, and the other of the two is provided with an inserting section 521 adapted to the inserting groove 311, and the inserting section 521 is embedded in the inserting groove 311. Of course, in other embodiments of the present application, the second elastic section 52 can be connected to the one end of the adjusting member 31 by screwing, welding, etc., and other variations based on the concept of the present application are within the scope of protection of the present application.

[0063] It is understandable that in this embodiment, the second elastic section 52 may be provided with a plug-in section 521 at one end connected to the adjusting member 31 and the plug-in slot 311 may be provided on the adjusting member 31, or the second elastic section 52 may be provided with a plug-in slot 311 at one end connected to the adjusting member 31 and the plug-in section 521 may be provided on the adjusting member 31. Figure 2 FIG. 5 shows a situation where the second elastic section 52 is connected to one end of the adjusting member 31 and is provided with an inserting section 521 , and the adjusting member 31 is provided with an inserting groove 311 .

[0064] Specifically, through the cooperation of the plug-in section 521 and the plug-in slot 311, the elastic member 50 and the adjustment member 31 can be quickly assembled without the use of additional fixings, shortening the assembly time and reducing production costs. At the same time, the close cooperation between the plug-in section 521 and the plug-in slot 311 can provide reliable mechanical connection strength, so that the force generated by the elastic member 50 during compression and rebound is stably transmitted to the adjustment member 31, avoiding abnormal shaking of the adjustment member 31 or adjustment failure due to looseness, and ensuring the accuracy and continuity of the cleaning operation. In addition, this design greatly improves the convenience of maintenance. When the elastic member 50 is damaged or its performance degrades, the plug-in section 521 can be directly pulled out of the plug-in slot 311, and the elastic member 50 can be quickly replaced without disassembling the entire adjustment assembly 30, significantly reducing the complexity and cost of maintenance.

[0065] For example, the first elastic section 51 and the cover plate 14 in this embodiment can be connected by screw connection, welding or clamping, etc. As long as it is other deformation methods based on the concept of this application, it is within the protection scope of this application.

[0066] Further, see Figure 6 As shown, the adjusting member 31 in this embodiment is provided with a through hole 312 for the connecting member 44 to pass through, and the second elastic section 52 is provided with an avoidance notch 522 , which corresponds to the position of the through hole 312 .

[0067] Specifically, the through hole 312 provides a precise penetration path for the connecting member 44, ensuring a stable connection between the connecting member 44 and the adjusting member 31, so that the power of the first drive component 41 can be reliably transmitted to the adjusting member 31, ensuring that the adjusting member 31 can stably switch between the first position and the second position; and the avoidance gap 522 on the second elastic section 52 corresponding to the through hole 312 can leave space for the movement of the connecting member 44, avoiding interference between the elastic member 50 and the connecting member 44 during compression and rebound, ensuring the normal functioning of the respective functions of the elastic member 50 and the connecting member 44, and effectively improving the smoothness and reliability of the operation of the adjusting component 30.

[0068] Further, see Figure 4 、 Figure 5 and Figure 7As shown, the cover plate 14 in this embodiment is further provided with a guide member 45 and a slider 4332, the slider 4332 is slidably provided on the guide member 45 and is driven and connected to the first drive assembly 41, and a mounting hole is provided on the slider 4332 (not shown in the drawings); the connecting member 44 includes a connecting rope 441, the first end of the connecting rope 441 is located in the mounting hole, and the first end of the connecting rope 441 has a stop protrusion (not shown in the drawings), the minimum cross-sectional area of ​​the stop protrusion is larger than the maximum cross-sectional area of ​​the mounting hole, the second end of the connecting rope 441 is embedded in the mounting groove 313 of the adjusting member 31 through the fixing portion 442, and the connecting member 441 is connected to the fixing portion 442. The connecting rope 441 has a taut state and a relaxed state; wherein, when the slider 4332 drives the connecting rope 441 to be in a taut state under the driving action 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, and 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 a relaxed state under the driving action 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 recovery action of the elastic member 50 and switches from the first position to the second position.

[0069] Specifically, the present application uses a connecting rope 441 as a transmission medium. Compared to traditional rigid connecting rods, the flexibility of the connecting rope 441 makes the internal spatial layout of the cleaning device more flexible, enabling power transmission along complex paths within a limited space. The connecting rope 441, driven by the slider 4332, can switch between a taut state and a relaxed state under the drive of the first drive assembly 41, thereby converting the movement of the first drive assembly 41 into a state transition of the connecting rope 441, thereby achieving linked control of the position of the adjusting member 31 and the state of the elastic member 50. When the connecting rope 441 is taut, the tension is used to drive the adjusting member 31 to rotate in the first rotational direction, causing the elastic member 50 to transition from a natural state to a compressed state, thereby efficiently transmitting the power of the first drive assembly 41 to the adjusting member 31. When the connecting rope 441 is relaxed, the elastic member 50 relies on its own elastic restoring force to push the adjusting member 31 to rotate in the opposite direction and reset, forming a closed-loop control. The overall structure is simple, eliminating the need for a complex mechanical transmission structure, reducing manufacturing costs, and achieving flexible and stable reciprocating adjustment functions.

[0070] At the same time, the combination of guide member 45 and slider 4332 provides a precise track for the movement of slider 4332, ensuring transmission stability, preventing wear and tear on 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 larger cross-sectional area than the mounting hole ensures that connecting rope 441 will not fall 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 portion 442, facilitating the rapid installation and removal of connecting rope 441 and adjusting member 31. This design combines connection stability with movement flexibility. It not only ensures that connecting rope 441 can reliably transmit power and displacement when slider 4332 moves on guide member 45, but also allows 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 and 5 As shown, the cover plate 14 in this embodiment is provided with a mounting portion 141, and the mounting portion 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 arranged 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 drawings); the first driving component 41 includes a driving component 43 and a transmission component 433. The driving component 43 is arranged on the bottom shell 13 and is driven and connected to the transmission component 433. The transmission component 433 includes a pushing member 4331. The pushing member 4331 is movably arranged on the driving component 43 and contacts the slider 4332. The pushing member 4331 can push the slider 4332 to slide on the guide rod 451 under the driving action of the driving component 43, thereby driving the connecting rope 441 to switch between a taut state and a relaxed state.

[0072] Specifically, mounting cavity 142 incorporates guide rod 451 and slider 4332 within the cover plate 14 structure, achieving compact assembly integration, effectively conserving space outside the device and preventing the risk of interference or damage caused by exposed components. Guide rod 451 extends along the axis of cleaning assembly 20 and mates with the guide hole of slider 4332, forming a stable linear motion track. This ensures precise positioning and smooth sliding of slider 4332 during operation, reducing friction loss and motion deviation, thereby enhancing the reliability of the transmission system of connecting rope 441. Furthermore, this enclosed installation method effectively isolates impurities such as dust and debris, reducing environmental erosion on internal transmission components, extending the device's service life, and facilitating maintenance and inspection.

[0073] Furthermore, driving force is precisely transmitted to slider 4332 via pusher 4331, pushing slider 4332 to slide on guide rod 451, thereby controlling the flexible switching of connecting rope 441 between a taut and a loose state. This design results in a compact structure and efficient transmission of the entire system, enabling precise control of the state of connecting rope 441 while facilitating installation and maintenance through a modular design, thereby enhancing the reliability and practicality of the equipment.

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

[0075] Specifically, the first drive motor 431 is driven and connected to the screw 432, which can efficiently convert the motor's rotational power into the rotation of the screw 432, providing a stable and reliable power source for the system; the layout of the screw 432 extending along the axis of the cleaning component 20, combined with the reciprocating motion characteristics of the pusher 4331 on the screw 432, can accurately convert the rotational motion of the screw 432 into linear motion, thereby achieving precise control of the state of the connecting rope 441. When the pusher 4331 moves toward the first drive motor 431, it can stably tighten the connecting rope 441, thereby driving the adjustment member 31 to switch to the first position and simultaneously storing energy in the elastic member 50; and when the pusher 4331 moves in the opposite direction, it can accurately release the tension of the connecting rope 441, allowing the elastic member 50 to push the adjustment member 31 to reset. This structure not only has high transmission efficiency and strong motion stability, but also can achieve precise adjustment of the action of the adjustment member 31 by controlling the speed and direction of the screw 432, meeting the needs of different working conditions. At the same time, the modular design facilitates installation, maintenance and replacement of components, reduces equipment maintenance costs, and improves the reliability and service life of the overall system.

[0076] That is to say, in this embodiment, the first drive motor 431 drives the screw rod 432 to rotate, thereby driving the pushing member 4331 to move back and forth on the screw rod 432 along the axial direction of the cleaning component 20, and then driving the connecting rope 441 to switch between the tightened state and the relaxed state, and then driving the adjusting member 31 to switch between the first position and the second position, and finally realizing the adjustment of the size of the opening 12.

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

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

[0079] Specifically, this embodiment arranges two position detection elements 60 on opposite sides of the transmission component 433. In this way, the movement position of the transmission component 433 can be accurately detected. When the transmission component 433 moves along the axis of the cleaning component 20, the trigger part 46 moves with the transmission component 433. When it contacts the position detection element 60, the position detection element 60 immediately sends a signal to stop the first drive motor 431 or change the direction of rotation, ensuring that the adjustment member 31 is accurately switched to the first position or the second position, greatly improving the accuracy of the cleaning mode switching. At the same time, the provision of the two position detection elements 60 can avoid mechanical damage to the transmission component 433 due to excessive movement, prevent the occurrence of faults such as the breaking of the connecting rope 441 and the jamming of the screw rod 432, and effectively improve the stability and reliability of the cleaning device.

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

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

[0082] On the other hand, the embodiment of the present application further provides a cleaning device, which includes the above-mentioned cleaning device, and therefore, the cleaning device includes all the technical effects of the above-mentioned cleaning device. Since the technical effects of the cleaning device have been described in detail above, they will not be repeated here.

[0083] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
