When the equipment completes its cleaning task or needs to overcome an obstacle, this mechanism needs to be lifted off the surface to be cleaned. Current cleaning mechanisms are very laborious to lift, requiring a high-powered motor to provide sufficient pulling force, resulting in a heavy overall weight and increased manufacturing costs. Utility Model Content
[0004] The main objective of this application is to provide a cleaning device that solves the problem that the lifting process of the existing cleaning mechanism is laborious, requires the use of a high-power motor, and results in a heavy overall weight and high manufacturing cost of the cleaning equipment.

The lifting component is connected between the first drive component and the lever lifting component. The lever lifting component is connected to the cleaning mechanism. Under the action of the lifting component, the lever lifting component can apply an external force to the cleaning mechanism to make the cleaning mechanism stand in the first position. Under the action of the lifting component, the lever lifting component can eliminate the external force applied to the cleaning mechanism and make the cleaning mechanism stand in the second position under the action of gravity.

[0021] When the lifting member is in the tensioned state, the slider moves downward along the length of the guide rod under the action of the lifting member, so as to drive the end of the lifting lever connected to the slider to move downward synchronously, and cause the end of the lifting lever connected to the cleaning mechanism to move upward along the height of the machine body.
[0022] When the lifting member is in the relaxed state, the end of the lifting lever connected to the cleaning mechanism moves downward along the height direction of the machine body under the action of the cleaning mechanism, so that the end of the lifting lever connected to the slider moves upward along the height direction of the machine body, and so that the slider moves upward along the length direction of the guide rod.
[0023] Furthermore, a groove is provided on the lifting lever, the groove extending along the length direction of the lifting lever and penetrating along the thickness direction of the lifting lever;

[0025] Furthermore, the slider is also provided with a limiting hole, the lifting member includes a pull rope, one end of the pull rope connected to the slider is located in the limiting hole, and the maximum cross-sectional area of the pull rope is smaller than the minimum cross-sectional area of the limiting hole.
[0026] Furthermore, the slider is also provided with an avoidance notch, which communicates with the limiting hole and extends along the height direction of the body. The pull rope is connected to one end of the slider and has a stop protrusion. The pull rope enters the limiting hole from the avoidance notch so that the stop protrusion abuts against the slider, and the minimum cross-sectional area of the stop protrusion is greater than the maximum cross-sectional area of the limiting hole.
[0027] Furthermore, the machine body is provided with rotatable rollers, and at least a portion of the lifting member is wound around the rollers.

The support is connected to the machine body, the cleaning body is connected to the support, and the cleaning body has an outwardly extended position that moves with the support to extend outward from the outer periphery of the machine body, and an inwardly retracted position that moves with the support to retract into the inner side of the machine body.

The guide assembly is connected between the machine body and the support.
[0034] Wherein, at least one of the second drive component and the guide component is connected to the lever lifting component.
[0035] Because this application lifts the cleaning mechanism by applying external force to it using a lever lifting component, the force amplification effect of the lever lifting component requires only a small driving force to achieve the lifting, thus saving energy. Compared to the lifting of cleaning mechanisms in the prior art, the lifting process of the cleaning mechanism in this application is more labor-saving, thus eliminating the need for a high-power motor to provide sufficient pulling force, reducing the overall weight of the cleaning device, and lowering the manufacturing cost of the cleaning device.

[0050] As mentioned in the background section, existing cleaning equipment typically has a cleaning mechanism at its bottom. When the cleaning equipment completes its cleaning task or needs to overcome obstacles, this cleaning mechanism needs to be lifted off the surface to be cleaned. However, lifting the cleaning mechanism is very laborious, requiring a high-power motor to provide sufficient pulling force, resulting in a heavy overall weight and increased manufacturing costs for the cleaning equipment. To address this, the inventors of this application have designed a novel cleaning device that solves the problem of the laborious lifting process of the cleaning mechanism in existing technologies, requiring a high-power motor, leading to a heavy overall weight and high manufacturing costs. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.
[0051] It should be noted that "the height direction of the fuselage 10" in this application refers to the attached... Figure 1 The direction indicated by the letter X, "the length direction of the lifting lever," refers to the attached... Figure 2 The direction indicated by the letter Y, "the direction of the thickness of the lifting lever," refers to the attached... Figure 2 The direction indicated by the letter Z in the middle, "first direction" refers to the attached... Figure 2 The direction indicated by the letter Y.
[0052] See Figures 1 to 8As shown, according to an embodiment of this application, a cleaning device is provided, which includes a body 10, a cleaning mechanism 20 and a drive mechanism 30.
[0053] The cleaning mechanism 20 is movably disposed at the bottom of the body 10, and has a first position in which it is raised along the height direction of the body 10 to move away from the surface to be cleaned, and a second position in which it is lowered along the height direction of the body 10 to move closer to the surface to be cleaned. The drive mechanism 30 is disposed on the body 10, and includes a first drive component 40, a lifting component 50 and a lever lifting component 60. The lifting component 50 is connected between the first drive component 40 and the lever lifting component 60, and the lever lifting component 60 is connected to the cleaning mechanism 20. Under the action of the lifting component 50, the lever lifting component 60 can apply an external force to the cleaning mechanism 20 to make the cleaning mechanism 20 stand in the first position, and under the action of the lifting component 50, the lever lifting component 60 can eliminate the external force applied to the cleaning mechanism 20 so that the cleaning mechanism 20 stands in the second position under the action of gravity.
[0054] In this embodiment, since the lifting member 50 is connected between the first drive assembly 40 and the lever lifting assembly 60, and the lever lifting assembly 60 is connected to the cleaning mechanism 20, when the cleaning device encounters an obstacle, the first drive assembly 40 can control the lifting member 50, so that the lever lifting assembly 60 can apply an external force to the cleaning mechanism 20 under the action of the lifting member 50, causing the cleaning mechanism 20 to be lifted along the height direction of the body 10 and placed in a first position away from the surface to be cleaned. This prevents the cleaning device from having difficulty crossing the obstacle due to a collision between the cleaning mechanism 20 and the obstacle, making it easier for the cleaning device to cross the obstacle and extending the service life of the cleaning mechanism 20. When the cleaning device needs to perform cleaning operations, the first drive assembly 40 can control the lifting member 50. At this time, the lever lifting assembly 60 can eliminate the external force applied to the cleaning mechanism 20 under the action of the lifting member 50. The cleaning mechanism 20 will descend along the height direction of the body 10 under the action of gravity and be placed in a second position, so that the surface to be cleaned can be cleaned.
[0055] Meanwhile, since this embodiment lifts the cleaning mechanism 20 by applying external force to it using the lever lifting component 60, the force amplification effect of the lever lifting component 60 allows for lifting of the cleaning mechanism 20 with only a small driving force, saving energy. Compared to the lifting of the cleaning mechanism 20 in the prior art, the lifting process of the cleaning mechanism 20 in this embodiment is more labor-saving, thus eliminating the need for a high-power motor to provide sufficient pulling force to the cleaning mechanism 20, reducing the overall weight of the cleaning device, and lowering the manufacturing cost of the cleaning device.
[0056] The appendix to this application Figure 2A schematic diagram showing the structure of the lever lifting assembly 60 without lifting the cleaning mechanism 20 is shown; (See attached diagram) Figure 3 A schematic diagram shows the structure in which the lever lifting assembly 60 has lifted the cleaning mechanism 20.
[0057] Furthermore, in this embodiment, the lifting member 50 has a relaxed state and a tense state under the driving action of the first driving component 40; wherein, when the lifting member 50 is in the tense state, the lever lifting component 60 can apply an external force to the cleaning mechanism 20 to make the cleaning mechanism 20 be in a first position; when the lifting member 50 is in the relaxed state, the lever lifting component 60 can eliminate the external force applied to the cleaning mechanism 20 and make the cleaning mechanism 20 be in a second position under the action of gravity.
[0058] Specifically, in this embodiment, by switching between the taut and slack states of the lifting member 50, the cleaning mechanism 20 can be driven to switch between a first position and a second position, thereby meeting the positional requirements of the cleaning device under different working conditions. It is worth noting that in this embodiment, "the lifting member 50 is in a taut state" means that the lifting member 50 is tightened under the pulling force of the first drive assembly 40, forming a rigid connection between the lifting member 50 and the first drive assembly 40; in this embodiment, "the lifting member 50 is in a slack state" means that the first drive assembly 40 stops applying pulling force to the lifting member 50, allowing the lifting member 50 to pick up tension and be in a free or slightly slack state.
[0059] Further, see Figures 2 to 3 As shown, the lever lifting assembly 60 in this embodiment includes a lifting lever 61, which is rotatably mounted on the body 10. One end of the lifting lever 61 is connected to the lifting member 50, and the other end is connected to the cleaning mechanism 20. When the lifting member 50 is in a taut state, the end of the lifting lever 61 connected to the lifting member 50 moves downward along the height direction of the body 10 under the action of the lifting member 50, so that the end of the lifting lever 61 connected to the cleaning mechanism 20 moves upward along the height direction of the body 10. When the lifting member 50 is in a slack state, the end of the lifting lever 61 connected to the cleaning mechanism 20 moves downward along the height direction of the body 10 under the action of the cleaning mechanism 20, so that the end of the lifting lever 61 connected to the lifting member 50 moves upward along the height direction of the body 10.
[0060] Specifically, in this embodiment, the rotatable characteristic of the lifting lever 61 is utilized to convert the movement of the lifting member 50 into the up-and-down movement of the cleaning mechanism 20. When the lifting member 50 is taut and exerts downward force, the connection end between the lifting lever 61 and the lifting member 50 moves downward, causing the connection end between the lifting lever 61 and the cleaning mechanism 20 to move upward through the lever principle, thereby lifting the cleaning mechanism 20. Conversely, when the lifting member 50 is slack, the gravity of the cleaning mechanism 20 causes the connection end between the lifting lever 61 and the cleaning mechanism 20 to move downward, thereby driving the connection end between the lifting lever 61 and the lifting member 50 to move upward, thereby lowering the cleaning mechanism 20. It is worth noting that, since the lifting lever 61 is used to lift the cleaning mechanism 20 in this embodiment, according to the lever principle, by reasonably designing the lever arm length of the lifting lever 61, a smaller force can be applied to the lifting member 50, and a larger lifting force can be generated at the connection end between the lifting lever 61 and the cleaning mechanism 20. In this way, the first drive component 40 with a smaller power can be used to drive the entire system, reducing the requirements for the drive device and saving energy and cost.
[0061] Meanwhile, the rotation of the lifting lever 61 in this embodiment is relatively smooth. Driven by the lifting member 50, the rising and falling process of the cleaning mechanism 20 is relatively gentle, reducing the impact and vibration during the movement, improving the overall stability of the cleaning device, and extending the service life of each component.
[0062] Further, see Figures 2 to 3 As shown, the lever lifting assembly 60 in this embodiment also includes a fixed shaft 62, which is disposed on the body 10. The lifting lever 61 has a through hole 601. The lifting lever 61 is sleeved on the fixed shaft 62 through the through hole 601 and can rotate around the fixed shaft 62. The lifting lever 61 includes a bent section 611, a first straight section 612, a second straight section 613, and a third straight section 614. The bent section 611 is connected to the first straight section 612 through a connecting section 615, and the connecting section 615 has a through hole 601. The first straight section 612 and the third straight section 614 extend in the same direction. The second straight section 613 is connected between the first straight section 612 and the third straight section 614. The end of the bent section 611 away from the first straight section 612 is connected to the lifting member 50. The end of the third straight section 614 away from the second straight section 613 is connected to the cleaning mechanism 20.
[0063] Specifically, the fixed shaft 62 provides a stable rotational support point for the lifting lever 61, ensuring that the lifting lever 61 can rotate stably around the fixed shaft 62, effectively guaranteeing the accuracy and reliability of the entire lever lifting assembly 60's movement. The lifting lever 61 includes a bent section 611, a first straight section 612, a second straight section 613, and a third straight section 614. This arrangement increases the structural strength of the lifting lever 61, allowing the forces from the lifting member 50 and the cleaning mechanism 20 to be distributed to different parts of the lifting lever 61, preventing the force from concentrating in one place and causing excessive local stress that could lead to the lifting lever 61 breaking.
[0064] Further, see Figure 3 As shown, in this embodiment, a plug-in section 616 is provided on the third straight segment 614. The plug-in section 616 protrudes from the surface of the third straight segment 614. A plug-in groove 201 is provided on the cleaning mechanism 20, and the plug-in section 616 is located in the plug-in groove 201.
[0065] Specifically, the connection between the plug segment 616 and the plug slot 201 enables a direct connection between the third straight segment 614 of the lifting lever 61 and the cleaning mechanism 20, effectively fixing them together. This allows the lifting lever 61 to smoothly transmit force to the cleaning mechanism 20, driving it to lift and ensuring the stability and reliability of the force transmission path. Simultaneously, the connection between the plug segment 616 and the plug slot 201 makes the installation and removal of the cleaning mechanism 20 more convenient and quick. During installation, simply align the plug segment 616 with the plug slot 201 and insert it to complete the connection; when repairing or replacing the cleaning mechanism 20, simply pull out the plug segment 616, without the need for complex tools or cumbersome operations, greatly improving the ease of maintenance and reducing maintenance costs and time.
[0066] Furthermore, to improve the stability of the rotation of the lifting lever 61, see [reference needed]. Figures 2 to 5As shown, the lever lifting assembly 60 in this embodiment also includes a guide component 63, which is connected between the lifting lever 61 and the lifting member 50. The guide component 63 includes a guide rod 631 and a slider 632. Specifically, the guide rod 631 is disposed on the body 10 and extends along the height direction of the body 10; the slider 632 has a guide hole 633, and the slider 632 is sleeved on the guide rod 631 through the guide hole 633 and can reciprocate along the length direction of the guide rod 631. The slider 632 is connected between the lifting member 50 and the lifting lever 61. When the lifting member 50 is in a taut state, the slider 632 moves downward along the length direction of the guide rod 631 under the action of the lifting member 50, so as to drive the lifting lever 61. The end connected to the slider 632 moves downward synchronously, causing the end of the lifting lever 61 connected to the cleaning mechanism 20 to move upward along the height direction of the machine body 10; when the lifting member 50 is in a relaxed state, the end of the lifting lever 61 connected to the cleaning mechanism 20 moves downward along the height direction of the machine body 10 under the action of the cleaning mechanism 20, causing the end of the lifting lever 61 connected to the slider 632 to move upward along the height direction of the machine body 10, causing the slider 632 to move upward along the length direction of the guide rod 631.
[0067] Specifically, the guide rod 631 is configured to define a unique path for the movement of the slider 632, ensuring that the slider 632 can only reciprocate along the length of the guide rod 631. This guarantees the directional accuracy of the lifting member 50 and the lifting lever 61 connected to the slider 632 during movement, preventing arbitrary swaying or deviation. As an intermediate component connecting the lifting member 50 and the lifting lever 61, the slider 632 effectively transmits the force applied by the lifting member 50 to the lifting lever 61, and simultaneously transmits the reaction force received by the lifting lever 61 to the lifting member 50, ensuring smooth force transmission between the two and enabling the entire lever lifting assembly 60 to operate normally. In other words, this embodiment, through precise guidance and stable force transmission and balance, makes the operation of the entire lever lifting assembly 60 more stable and reliable, reducing malfunctions and abnormalities caused by unstable movement or uneven force, improving the overall stability and reliability of the cleaning device, and reducing the failure rate of the cleaning device.
[0068] Further, see Figure 2 as well as Figure 4 As shown, in this embodiment, the lifting lever 61 is provided with a groove 617, which extends along the length direction of the lifting lever 61 and passes through the thickness direction of the lifting lever 61; the slider 632 is provided with a rod 634, which protrudes from the surface of the slider 632 and passes through the groove 617, and the end of the rod 634 away from the slider 632 has a stop block 635.
[0069] Specifically, the groove 617 and the rod 634 enable the connection between the slider 632 and the lifting lever 61, allowing them to move in tandem. This ensures that under the action of the lifting member 50, the movement of the slider 632 drives the corresponding end of the lifting lever 61 to move up and down. Simultaneously, since the groove 617 in this embodiment extends along the length of the lifting lever 61, and the rod 634 passes through the groove 617, when the lifting member 50 is taut, the slider 632 moves downward along the guide rod 631 under the action of the lifting member 50. During this process, the rod 634 on the slider 632 moves within the groove 617 along its extension direction, ensuring that the connection between the lifting lever 61 and the slider 632 can move smoothly downward, causing the connection between the lifting lever 61 and the cleaning mechanism 20 to move upward, thus lifting the cleaning mechanism 20. In addition, in this embodiment, a stop block 635 is provided at the end of the rod 634 away from the slider 632. This prevents the rod 634 from detaching from the groove 617 during the movement of the slider 632, effectively improving the stability and reliability of the connection between the slider 632 and the lifting lever 61.
[0070] Further, see Figures 4 to 5 As shown, in this embodiment, the slider 632 is also provided with a limiting hole 636. The lifting member 50 includes a pull rope 51, one end of which is connected to the slider 632 and is located inside the limiting hole 636. The maximum cross-sectional area of the pull rope 51 is smaller than the minimum cross-sectional area of the limiting hole 636. It should be noted that in this embodiment, the "cross-sectional area of the pull rope 51" refers to the area of the cross-section obtained by cutting the pull rope 51 along a direction perpendicular to its length; the "cross-sectional area of the limiting hole 636" refers to the area of the cross-section obtained by cutting the limiting hole 636 along a direction perpendicular to its extension.
[0071] Specifically, the limiting hole 636 provides a limiting function for the pull rope 51, preventing it from detaching from the slider 632 during operation and ensuring the accuracy and stability of the pull force transmission. Meanwhile, since the maximum cross-sectional area of the pull rope 51 in this embodiment is smaller than the minimum cross-sectional area of the limiting hole 636, this design allows the pull rope 51 some room to move within the limiting hole 636, preventing it from being squeezed and worn against the inner wall of the limiting hole 636 during operation. Furthermore, it allows the pull rope 51 to be easily inserted into the limiting hole 636, improving assembly efficiency.
[0072] Further, see Figure 4 as well as Figure 5As shown, the slider 632 in this embodiment is also provided with a clearance notch 637. The clearance notch 637 is connected to the limiting hole 636 and extends along the height direction of the body 10. The pull rope 51 is connected to one end of the slider 632 and has a stop protrusion 52. The pull rope 51 enters the limiting hole 636 from the clearance notch 637 so that the stop protrusion 52 abuts against the slider 632, and the minimum cross-sectional area of the stop protrusion 52 is greater than the maximum cross-sectional area of the limiting hole 636.
[0073] Specifically, the clearance notch 637 facilitates the installation of the pull rope 51, allowing it to smoothly enter the limiting hole 636 through the clearance notch 637; the stop protrusion 52 prevents the pull rope 51 from detaching from the limiting hole 636 during operation. That is, when the pull rope 51 needs to be connected to the slider 632, it is only necessary to insert the pull rope 51 into the limiting hole 636 through the clearance notch 637. At this time, since the minimum cross-sectional area of the stop protrusion 52 is greater than the maximum cross-sectional area of the limiting hole 636, the stop protrusion 52 will abut against the slider 632, making it difficult for the pull rope 51 to detach from the limiting hole 636 under external force, effectively ensuring the stability and reliability of the connection between the lifting member 50 and the slider 632.
[0074] Further, see Figure 8 As shown, in this embodiment, the body 10 is provided with a rotatable roller 64, and at least part of the lifting member 50 is wrapped around the roller 64.
[0075] Specifically, the roller 64 can change the direction of force on the lifting member 50. When the cleaning device is running, the rotation characteristics of the roller 64 can make the first drive assembly 40 less effort when controlling the lifting member 50, reduce the power required by the first drive assembly 40, improve energy utilization efficiency, and reduce the energy consumption of the cleaning device.
[0076] Furthermore, to ensure the stability of the cleaning mechanism 20 during the lifting process, see [reference needed]. Figure 2 , Figure 4 as well as Figure 8 As shown, in this embodiment, there are two lifting levers 61. The two lifting levers 61 are located at opposite ends of the guide member 63 along the first direction and are respectively connected to the slider 632. Both lifting levers 61 are connected to the cleaning mechanism 20.
[0077] Specifically, the two lifting levers 61 are located at opposite ends of the guide component 63, which makes the cleaning mechanism 20 more balanced when subjected to force. When the slider 632 moves and drives the cleaning mechanism 20 through the lifting levers 61, the lifting levers 61 located at both ends of the guide component 63 can evenly distribute the weight of the cleaning mechanism 20 and the various forces generated during the cleaning process, preventing the cleaning mechanism 20 from tilting, shaking or even being damaged due to uneven force, and ensuring the stability and reliability of the cleaning mechanism 20 during operation.
[0078] Further, see Figure 7 As shown, the first drive assembly 40 in this embodiment includes a first gearbox 41, a reel 42, and a first drive member 43. The first gearbox 41 is disposed on the machine body 10 and includes a first housing 411 and a first gear set 412. The first gear set 412 is disposed within the first housing 411. A first shell 413 is disposed on the first housing 411, forming an installation cavity. A clearance channel 414 is provided on the side wall of the first shell 413. The reel 42 is rotatably disposed within the installation cavity and connected to the first gear set 412 via a rotating shaft 415. One end of a lifting member 50, away from the lever lifting assembly 60, is wound around the reel 42, and the lifting member 50 extends through the clearance channel 414. The first drive member 43 is disposed on the first housing 411 and drivenly connected to the first gear set 412 to drive the first gear set 412 to rotate, thereby rotating the reel 42. Exemplarily, the first drive member 43 in this embodiment includes a drive motor.
[0079] Specifically, the first gear set 412 plays a crucial role in power transmission and conversion between the first drive member 43 and the reel 42, enabling the reel 42 to generate sufficient pulling force to drive the lifting member 50, thereby realizing the lifting and lowering operation of the cleaning mechanism 20. The first housing 411 and the first shell 413 provide a relatively enclosed space for the first gear set 412 and the reel 42, respectively. The first housing 411 encloses the first gear set 412 inside, preventing external dust, debris, etc. from entering the interior of the first housing 411 and avoiding contamination of the first gear set 412. The wear and malfunctions between the gears 232 extend the service life of the first gear set 412. The mounting cavity formed by the first housing 413 further protects the spool 42, preventing it from being disturbed by external factors and ensuring its normal rotation. The clearance channel 414 on the side wall of the first housing 413 provides a fixed exit path for the lifting member 50, allowing it to be orderly pulled out of the mounting cavity. This avoids the lifting member 50 from getting tangled or interfering with other components during movement, ensuring the smooth movement of the lifting member 50.
[0080] In other words, in this embodiment, when the cleaning device encounters an obstacle, the first drive member 43 controls the rotation of the spool 42 through the first gear set 412. The lifting member 50 is wound around the spool 42 and is in a taut state as the spool 42 rotates. At this time, the lifting member 50 applies a downward pulling force to the slider 632 in the guide member 63, so that the slider 632 moves downward along the length direction of the guide rod 631, thereby driving the connection end between the lifting lever 61 and the slider 632 to move downward along with the slider 632, thereby causing the connection end between the lifting lever 61 and the cleaning mechanism 20 to move upward and realize the lifting of the cleaning mechanism 20.
[0081] Further, see Figure 6 As shown, the cleaning mechanism 20 in this embodiment includes a cleaning body 21, a support 22, a second drive assembly 23, and a guide assembly 24. The support 22 is connected to the body 10, and the cleaning body 21 is connected to the support 22. The cleaning body 21 has an outwardly extended position that moves with the support 22 to extend outward from the outer periphery of the body 10, and an inwardly retracted position that moves with the support 22 to retract inward from the inner side of the body 10. The second drive assembly 23 is drivenly connected to the support 22 to drive the cleaning body 21 to switch between the outwardly extended position and the inwardly retracted position. The guide assembly 24 is connected between the body 10 and the support 22. At least one of the second drive assembly 23 and the guide assembly 24 is connected to the lever lifting assembly 60.
[0082] It is understood that in this embodiment, the second drive component 23 may be connected to the lever lifting component 60, the guide component 24 may be connected to the lever lifting component 60, or both the second drive component 23 and the guide component 24 may be connected to the lever lifting component 60.
[0083] Specifically, when the cleaning device in this embodiment needs to clean corners and other edge areas, the second drive component 23 drives the bracket 22 to move, which in turn moves the cleaning body 21 to an outward position to clean the corners and other edge areas, ensuring that the corners are cleaned thoroughly and avoiding blind spots after cleaning. When there are no corners in the area to be cleaned, the second drive component 23 drives the bracket 22 to move the cleaning body 21 to an inward position, so that the cleaning body 21 can clean the area according to a predetermined cleaning route. The guide component 24 improves the stability of the cleaning body 21 as it moves with the bracket 22.
[0084] Specifically, see Figure 6As shown, the second drive assembly 23 in this embodiment includes a second drive member 231, a gear 232, and a rack 233. The second drive member 231 is installed inside the body 10 and is driven by the gear 232 to drive the gear 232 to rotate circumferentially. The rack 233 is installed on the bracket 22 and meshes with the gear 232. The rack 233 extends along a first direction so that when the gear 232 and rack 233 mesh, the rack 233 can move a certain distance relative to the gear 232 along the first direction, thereby ensuring that the bracket 22 can drive the cleaning body 21 to move between an outwardly expanding position and an inwardly retracted position along the first direction. Exemplarily, the second drive member 231 in this embodiment includes a drive motor.
[0085] Specifically, to ensure the reliability of the meshing between gear 232 and rack 233, see [reference needed]. Figure 6 As shown, the second drive assembly 23 also includes a second housing 234, which covers the gear 232. The second housing 234 has a cavity on the side near the rack 233 for the rack 233 to pass through, and the second housing 234 also has a plug groove 201 for the plug section 616 to be inserted.
[0086] Specifically, see Figure 6 As shown, the guide component 24 in this embodiment includes a sliding block 241 and a guide rail 242. The sliding block 241 is disposed inside the body 10, and the guide rail 242 is disposed on the bracket 22 and extends along a first direction. The guide rail 242 is connected to the sliding block 241 and can slide relative to the sliding block 241 along the bracket 22 in the first direction. In this embodiment, the sliding engagement between the sliding block 241 and the guide rail 242 guides the cleaning body 21 to move smoothly along the bracket 22 in the first direction. It is worth noting that the sliding block 241 in this embodiment is provided with a insertion slot 201 for the insertion section 616 to be inserted.
[0087] 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.
[0088] 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.
[0089] 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.
