Description

Technical Field

[0001] This utility model relates to the field of cleaning appliances, and in particular to a cleaning device and cleaning system. Background Technology

[0002] With the development of technology, fewer people are choosing to manually clean their homes, while more are opting for automated cleaning devices. These devices clean surfaces by contacting them with the work surface, such as the floor. In related technologies, cleaning devices feature cleaning components that can automatically raise, lower, and disassemble to meet a wider range of operational needs.

[0003] However, the driving structures for the automatic lifting and disassembly of cleaning components in related technologies are complex and costly. Therefore, simplifying the driving structure for the automatic lifting and disassembly of cleaning components and reducing costs are technical problems that need to be solved. Utility Model Content

[0008] According to the cleaning device of this utility model embodiment, a drive motor drives a lifting component to move up and down, thereby enabling the cleaning component to lift. By increasing the vertical interference between the cleaning component and the machine body, and utilizing a limiting structure on the machine body, when the cleaning component needs to be removed, the drive motor drives the lifting component upwards.

[0048] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] The following is for reference. Figures 1-2 A cleaning device 100 according to an embodiment of the present invention is described.

[0050] Reference Figures 1-2According to a first aspect embodiment of the present invention, a cleaning device 100 includes a body 10 and a first cleaning component 20. The body 10 has a limiting structure 101, which can be located at the bottom of the body 10. The first cleaning component 20 includes a drive component 30 and a cleaning part 50. The drive component 30 is mounted on the body 10 and includes a drive motor 35 and a lifting component 40 that can move up and down. The drive motor 35 is tractively connected to the lifting component 40 to drive the lifting component 40 to move.

[0051] The drive motor 35 drives the lifting component 40, causing the lifting component 40 to rise or fall, thereby raising or lowering the cleaning component 50. When the drive motor 35 drives the lifting component 40 to fall, the cleaning component 50 also falls; when the drive motor 35 drives the lifting component 40 to rise, the cleaning component 50 also rises. The raising and lowering of the cleaning component 50 can be controlled as needed. For example, when the cleaning component 50 needs to clean the work surface, it can be lowered to contact the work surface for cleaning; for example, when the cleaning component 50 does not need to clean the work surface, the lifting component 40 can be raised to store the cleaning component 50 in the machine body 10. For example, if the work surface is uneven during the cleaning process, the height of the cleaning component 50 can be adjusted by raising and lowering it to adapt to different working conditions.

[0052] The first cleaning component 20 can be used for wet cleaning. The cleaning device 100 may include a liquid supply component for supplying cleaning fluid to the cleaning part 50 of the first cleaning component 20. The cleaning part 50 of the first cleaning component 20 may include a mounting plate 51 and a cleaning element 56, with the cleaning element 56 mounted on the mounting plate 51. The lifting component 40 may be detachably connected to the cleaning plate of the cleaning part 50. The cleaning element 56 of the first cleaning component 20 is made of an absorbent material, such as a fibrous material. For example, the cleaning element 56 of the first cleaning component 20 may be a cloth, sponge, etc.

[0053] The cleaning component 50 and the lifting component 40 are detachably connected, allowing the cleaning component 50 to be disassembled. For example, when the cleaning component 50 needs to be cleaned, it can be removed. Similarly, if certain work surfaces are unsuitable for cleaning by the first cleaning component 20, the cleaning component 50 can be removed. For instance, when the first cleaning component 20 is used for wet cleaning, if the work surface is unsuitable for wet cleaning, such as a soft material like carpet, the cleaning component 50 can be separated from the lifting component 40, preventing wastewater from the cleaning component 50 from contaminating the work surface.

[0054] The limiting structure 101 on the body 10 is used to block the upward movement of the cleaning component 50 during the upward movement of the lifting component 40, so as to separate the cleaning component 50 from the lifting component 40. When the first cleaning assembly 20 is working normally, the drive motor 35 drives the lifting component 40 to move the cleaning component 50 up and down. When it is necessary to remove the cleaning component 50 from the first cleaning assembly 20, the drive motor 35 can drive the lifting component 40 to move upward, so that the cleaning component 50 moves upward until it interferes with the limiting structure 101 on the body 10. The lifting component 40 continues to move upward, while the cleaning component 50 is blocked by the limiting structure 101 and cannot continue to move upward. In this way, as the lifting component 40 continues to move upward, the cleaning component 50 gradually separates from the lifting component 40 until the cleaning component 50 falls off, thereby realizing the automatic disassembly of the cleaning component 50.

[0055] Based on the principle that the lifting component 40 is driven up and down by the drive motor 35 to achieve the lifting function of the cleaning component 50, the amount of interference between the cleaning component 50 and the machine body 10 in the vertical direction is increased, and the limiting structure 101 on the machine body 10 is used to achieve the automatic disassembly or detachment of the cleaning component 50. Specifically, the amount of interference between the cleaning component 50 and the machine body 10 in the vertical direction can be increased by increasing the lifting stroke of the lifting component 40.

[0056] When it is necessary to install the cleaning component 50 onto the body 10, the drive motor 35 can drive the lifting part to descend to a suitable position to facilitate manual or automatic connection of the cleaning component 50 to the lifting part.

[0057] Optionally, at least a portion of the base 11 of the body 10 can constitute the aforementioned limiting structure 101. By using at least a portion of the base 11 of the body 10 as the limiting structure 101, it is possible to eliminate the need to separately set a limiting structure 101 on the body 10, thus simplifying the overall structure.

[0058] According to the cleaning device 100 of this utility model embodiment, the lifting component 40 is driven up and down by the drive motor 35 to achieve the lifting function of the cleaning component 50. Furthermore, by increasing the interference between the cleaning component 50 and the body 10 in the vertical direction, and simultaneously utilizing the limiting structure 101 on the body 10, when it is necessary to remove the cleaning component 50, the drive motor 35 drives the lifting component 40 upwards. When the cleaning component 50 moves upwards and interferes with the limiting structure 101 on the body 10, the lifting component 40 continues to move upwards, while the cleaning component 50 is restrained by the limiting structure 101. The obstruction at point 1 prevents further upward movement. As the lifting component 40 continues to move upward, the cleaning component 50 gradually separates from the lifting component 40 until the cleaning component 50 detaches, thus enabling automatic disassembly of the cleaning component 50. The automatic disassembly of the cleaning component 50 is achieved by using the drive assembly 30 that drives the lifting and lowering of the cleaning component 50, eliminating the need for an additional disassembly mechanism. This simplifies the drive structure for lifting and lowering the cleaning component 50 and for automatic disassembly, reducing costs. The simplified drive structure also facilitates the miniaturization of the cleaning device 100.

[0059] Reference Figures 1-2 According to some embodiments of this utility model, the cleaning device 100 further includes a second cleaning component, which is disposed on the body 10. The first cleaning component 20 is used for wet cleaning, and the second cleaning component is used for dry cleaning. The cleaning device 100 may include a liquid supply component for supplying cleaning fluid to the cleaning part 50 of the first cleaning component 20, and the cleaning part 50 of the second cleaning component may include a brush. When the working surface is a hard material such as marble floor, tile floor, or wooden floor, the first cleaning component 20 can be used for cleaning; when the working surface is a soft material such as carpet, the second cleaning component can be used for cleaning. The first cleaning component 20 and the second cleaning component can work simultaneously, or the first cleaning component 20 can work alone; when cleaning objects that cannot be treated with water, such as carpets, the first cleaning component 20 does not work, and the second cleaning component works to avoid contaminating the working surface. By setting the first cleaning component 20 and the second cleaning component, the cleaning device 100 can have different cleaning functions to meet more cleaning needs.

[0060] According to some embodiments of this utility model, refer to Figures 1-2 The lifting component 40 has a first position, a second position and a third position arranged sequentially from top to bottom. The lifting component 40 is configured to drive the cleaning component 50 to move up and down during the movement between the second position and the third position, and to block the upward movement of the cleaning component 50 by the limiting structure 101 during the upward movement from the second position to the first position, so as to separate the cleaning component 50 from the lifting component 40.

[0061] For example, when the lifting component 40 is in the third position, the cleaning component 50 contacts the working surface, which can clean the working surface; during the process of the lifting component moving upward from the third position to the second position, the cleaning component 50 gradually moves upward; when the lifting component is in the second position, the cleaning component 50 disengages from the working surface; during the process of the lifting component moving upward from the second position to the first position, the limiting structure 101 blocks the upward movement of the cleaning component 50, causing the cleaning component 50 to separate from the lifting component 40; when the lifting component 40 is in the first position, the cleaning component 50 is completely separated from the lifting component 40.

[0062] When the cleaning component 50 of the first cleaning assembly 20 is normally connected to the lifting component 40, the cleaning component 50 can work normally, and the lifting component 40 can be controlled to rise and fall between the second and third positions as needed. For example, when the cleaning component 50 needs to clean the work surface, the drive motor 35 can drive the lifting component 40 to move downward from the second position to the third position, so that the cleaning component 50 moves downward and contacts the work surface; when the cleaning component 50 contacts the work surface to clean it, the drive motor 35 can drive the lifting component 40 to rotate, so that the cleaning component 50 rotates to clean the work surface. For example, during the cleaning process of the cleaning component 50, if the height of the work surface increases or there are low obstacles on the work surface, the drive motor 35 can drive the lifting component 40 to move upward, so that the cleaning component 50 moves upward; when the cleaning device 100 passes over a higher position of the work surface or an obstacle, the drive motor 35 can drive the lifting component 40 to move downward, so that the cleaning component 50 moves downward to contact the current work surface, thus adapting to different working conditions of the work surface. For example, when the cleaning component 50 finishes cleaning the work surface, the drive motor 35 can drive the lifting component 40 to move upward to the second position, so as to move the cleaning component 50 upward and thus store the cleaning component 50 in the body 10.

[0063] Specifically, when the lifting component 40 is in the third position, the cleaning component 50 is located below the limiting structure 101 and is spaced apart from the limiting structure 101 in the vertical direction; when the lifting component 40 is in the second position, the cleaning component 50 is located below the limiting structure 101, and the cleaning component 50 is just in contact with the limiting structure 101 or the distance between the cleaning component 50 and the limiting structure 101 is small. As the lifting component 40 moves upward from the third position to the second position, the distance between the cleaning component 50 and the limiting structure 101 gradually decreases.

[0064] When it is necessary to automatically detach the cleaning component 50, the drive motor 35 drives the lifting component 40 to move upward to the first position, so that the cleaning component 50 is disengaged from the lifting component 40. For example, when the lifting component 40 is in the third position or between the third and second positions, the drive motor 35 drives the lifting component 40 to move upward to the second position. At this time, the cleaning component 50 is just in contact with the limiting structure 101 or the distance between the cleaning component 50 and the limiting structure 101 is small. The drive motor 35 continues to drive the lifting component 40 to move upward, while the cleaning component 50 is blocked by the limiting structure 101 and cannot move upward with the lifting component 40. During the process of the drive motor 35 driving the lifting component 40 to move upward from the second position to the first position, the cleaning component 50 and the lifting component 40 gradually separate until the lifting component 40 moves upward to the first position, at which point the cleaning component 50 falls off the body 10.

[0065] For example, when the lifting component 40 is in the second position, the cleaning component 50 is just in contact with the limiting structure 101 or the distance between the cleaning component 50 and the limiting structure 101 is small. The drive motor 35 continues to drive the lifting component 40 to move upward, while the cleaning component 50 is blocked by the limiting structure 101 and cannot move upward with the lifting component 40. During the process of the drive motor 35 driving the lifting component 40 to move upward from the second position to the first position, the cleaning component 50 and the lifting component 40 gradually separate until the lifting component 40 moves upward to the first position, at which point the cleaning component 50 falls off the body 10.

[0066] When it is necessary to install the cleaning component 50 onto the machine body 10, the drive motor 35 can drive the lifting component 40 to move downward to the second position, or downward to the third position, or downward to a position between the third and second positions. At this time, the cleaning component 50 can be connected to the lifting component 40 so that the cleaning component 50 can be installed onto the lifting component 40 and the cleaning component 50 can perform cleaning work normally.

[0067] According to some embodiments of this utility model, refer to Figures 1-2 The lifting component 40 is rotatable, and its axis of rotation extends vertically. The drive assembly 30 includes a mounting bracket 31 with a receiving cavity 32. A guide 33 is provided within the receiving cavity 32. At least a portion of the lifting component 40 is located within the receiving cavity 32; for example, the main body of the lifting component 40 is located within the receiving cavity 32, and the lower end of the lifting component 40 can extend downwards to the outside of the receiving cavity 32. The guide 33 is threadedly engaged with the lifting component 40, converting the rotational motion of the lifting component 40 into vertical motion.

[0068] The drive assembly 30 includes a mounting bracket 31, which has a receiving cavity 32. The receiving cavity 32 serves to receive the guide 33 and protect the internal components.

[0069] The lifting component 40 is rotatable, allowing it to rotate by engaging with a threaded connection. The guide 33 is threadedly engaged with the lifting component 40, converting the rotation of the lifting component 40 into vertical movement. When the drive motor 35 drives the lifting component 40 to rotate, because the lifting component 40 is threadedly connected to the guide 33 within the mounting bracket 31, the lifting component 40 also moves vertically while rotating. Through the threaded engagement of the guide 33 and the lifting component 40, rotational motion can be converted into vertical motion, facilitating the vertical movement of the lifting component 40.

[0070] For example, when the drive motor 35 drives the lifting component 40 to rotate forward, the threaded engagement between the lifting component 40 and the guide 33 allows the lifting component 40 to move downwards while rotating forward; when the drive motor 35 drives the lifting component 40 to rotate in reverse, the threaded engagement between the lifting component 40 and the guide 33 allows the lifting component 40 to move upwards while rotating in reverse. Specifically, when the lifting component 40 is in the third position, it can rotate forward to drive the cleaning component 50 to rotate forward, thereby cleaning the work surface.

[0071] According to some embodiments of this utility model, refer to Figures 1-2 The guide member 33 is provided with a guide channel 34 extending in the vertical direction. The lifting member 40 passes through the guide channel 34. The inner peripheral wall of the guide channel 34 is provided with a first thread structure 341, and the outer peripheral wall of the lifting member 40 is provided with a second thread structure 4311. The second thread structure 4311 engages with the first thread structure 341.

[0072] The guide channel 34 serves to accommodate and guide the lifting component 40, providing space for its vertical movement. The second threaded structure 4311 on the outer peripheral wall of the lifting component 40 engages with the first threaded structure 341 on the inner peripheral wall of the guide channel 34, thereby converting the rotational motion of the lifting component 40 into vertical motion. For example, when the lifting component 40 rotates, the second threaded structure 4311 on its outer peripheral wall engages with the first threaded structure 341 on the guide member 33, and under the guidance of the first threaded structure 341 on the guide member 33, the lifting component 40 can move upward or downward while rotating.

[0073] According to some embodiments of this utility model, refer to Figures 1-2The lifting component 40 includes a lifting shaft 41 and a mating structure 42. The lifting shaft 41 extends in the vertical direction. The mating structure 42 includes a mating part 43 and a transmission structure. The mating part 43 is sleeved on the outer periphery of the lifting shaft 41. The transmission structure is disposed between the mating part 43 and the lifting shaft 41. The outer periphery of the mating part 43 is provided with a second thread structure 4311. The cleaning component 50 is detachably connected to the lower end of the lifting shaft 41. The drive motor 35 is driven by the lifting shaft 41. The drive motor 35 can drive the lifting shaft 41 to rotate. Since there is a transmission structure between the lifting shaft 41 and the mating part 43, the transmission structure is configured to transmit the rotational power of the lifting shaft 41 to the mating part 43 to drive the mating part 43 to rotate. Since the mating part 43 is threadedly connected to the guide part 33, the guide part 33 can guide the mating part 43 to move in the vertical direction while the mating part 43 rotates.

[0074] The lifting component 40 has a first position, a second position, and a third position arranged sequentially from top to bottom. The lifting component 40 is configured to drive the cleaning component 50 to move up and down during the movement between the second position and the third position, and to block the upward movement of the cleaning component 50 by the limiting structure 101 during the upward movement from the second position to the first position, so as to separate the cleaning component 50 from the lifting component 40.

[0075] For example, when the lifting component 40 is in the third position, the cleaning component 50 contacts the working surface, which can clean the working surface; during the process of the lifting component moving upward from the third position to the second position, the cleaning component 50 gradually moves upward; when the lifting component is in the second position, the cleaning component 50 disengages from the working surface; during the process of the lifting component moving upward from the second position to the first position, the limiting structure 101 blocks the upward movement of the cleaning component 50, causing the cleaning component 50 to separate from the lifting component 40; when the lifting component 40 is in the first position, the cleaning component 50 is completely separated from the lifting component 40.

[0076] When it is necessary to automatically remove the cleaning component 50, the drive motor 35 drives the lifting component 40 to move upward to the first position. During this process, when the cleaning component 50 comes into contact with the limiting structure 101, the cleaning component 50 can no longer move upward with the lifting component 40, while the lifting component 40 continues to move upward. The cleaning component 50 and the lifting component 40 gradually separate until the lifting component 40 moves upward to the first position, at which point the cleaning component 50 falls off the machine body 10.

[0077] The transmission structure is configured to transmit the rotational power of the lifting shaft 41 to the mating member 43, thereby driving the mating member 43 to rotate. During the process of the lifting component 40 moving downward from the first position to the second position, or moving downward from the second position to the third position, or moving upward from the third position to the second position, or moving upward from the second position to the first position, the transmission structure can transmit the rotational power of the lifting shaft 41 to the mating member 43, thereby causing the mating member 43 to rotate. Through the threaded connection between the mating member 43 and the guide member 33, the mating member 43 can move upward or downward while rotating.

[0078] When the lifting component 40 is in the third position, the power transmission between the lifting shaft 41 and the mating part 43 is disconnected. The transmission structure cannot transmit the rotational power of the lifting shaft 41 to the lifting shaft 41. As a result, when the lifting component 40 is in the third position, the mating part 43 is stationary, and the lifting shaft 41 can rotate relative to the mating part 43 without continuing to move in the up and down direction. Thus, when the lifting component 40 is in the third position, the working surface is cleaned by the rotation of the cleaning component 50.

[0079] For example, when the lifting component 40 is in the third position, the cleaning component 50 is in contact with the working surface, and the power transmission between the lifting shaft 41 and the mating part 43 is disconnected, allowing the lifting shaft 41 to rotate relative to the mating part 43, thus achieving the function of cleaning the working surface. When the lifting component 40 moves from the third position to the second position, it drives the cleaning component 50 to move upward. When the lifting component 40 moves from the second position to the third position, it drives the cleaning component 50 to move downward. When the lifting component 40 is in the second position, the cleaning component 50 is detached from the working surface. When the lifting component 40 moves from the second position to the first position, the limiting structure 101 blocks the upward movement of the cleaning component 50, causing the cleaning component 50 to separate from the lifting component 40. When the lifting component 40 is in the first position, the cleaning component 50 is completely separated from the lifting component 40. When the lifting component 40 moves from the first position to the second position, the lifting part moves downward. When it reaches the second position, the cleaning component 50 can be installed at the lower end of the lifting part.

[0080] According to some embodiments of this utility model, refer to Figures 1-2 The drive assembly 30 includes a first transmission gear 36 and a second transmission gear 37 that mesh with each other. The first transmission gear 36 is located inside the receiving cavity 32 and sleeved on the outer periphery of the lifting shaft 41. The first transmission gear 36 is fixed relative to the lifting shaft 41. The first transmission gear 36 and the mating part 43 are arranged at intervals along the axial direction of the lifting shaft 41. For example, the first transmission gear 36 is located on the lower side of the mating part 43. The second transmission gear 37 is connected to the drive motor 35. The second transmission gear 37 can be located inside the receiving cavity 32, and the drive motor 35 can be located outside the receiving cavity 32.

[0081] In this configuration, the first transmission gear 36 and the second transmission gear 37 mesh with each other. When the drive motor 35 drives the second transmission gear 37 to rotate, it can drive the first transmission gear 36 to rotate. The first gear is fixed relative to the lifting shaft 41, thereby driving the lifting shaft 41 to rotate. Since the first gear is fixed relative to the lifting shaft 41, the first transmission gear 36 and the lifting shaft 41 move synchronously. The first transmission gear 36 and the lifting shaft 41 rotate synchronously, or the first transmission gear 36 and the lifting shaft 41 rotate synchronously and move synchronously in the up and down direction.

[0082] It is understandable that when the lifting shaft 41 rotates and moves in the vertical direction, the first transmission gear 36 also rotates and moves in the vertical direction. The second transmission gear 37 meshes with the first transmission gear 36. The length of the transmission teeth of the second transmission gear 37 in the vertical direction can be determined according to the stroke of the first transmission gear 36 in the vertical direction, so that the first transmission gear 36 can maintain a meshing relationship with the second transmission gear 37 during the vertical movement.

[0083] According to some embodiments of this utility model, refer to Figures 1-2 The transmission structure includes a first transmission structure 441 and a second transmission structure 442 arranged axially spaced along the mating member 43. For example, the second transmission structure 442 may be located below the first transmission structure 441. The first transmission structure 441 is configured to transmit the power of rotation of the lifting shaft 41 in a first direction to the mating member 43, thereby causing the mating member 43 to rotate and move downward in the first direction. The second transmission structure 442 is configured to transmit the power of rotation of the lifting shaft 41 in a second direction to the mating member 43, thereby causing the mating member 43 to rotate and move upward in the second direction, which is opposite to the first direction. The lower end of the first threaded structure 341 has a threaded locking structure 342. When the lifting member 40 is in the third position, the threaded locking structure 342 engages with the first threaded structure 341 to restrict the rotation of the mating member 43 in the first direction.

[0084] The first direction mentioned above can be clockwise, and the second direction can be counterclockwise.

[0085] When the drive motor 35 drives the lifting shaft 41 to rotate in the first direction, the first transmission structure 441 is configured to transmit the power of the lifting shaft 41 rotating in the first direction to the mating part 43, so as to drive the mating part 43 to rotate in the first direction and move downward; when the drive motor 35 drives the lifting shaft 41 to rotate in the second direction, the second transmission structure 442 is configured to transmit the power of the lifting shaft 41 rotating in the second direction to the mating part 43, so as to drive the mating part 43 to rotate in the second direction and move upward.

[0086] For example, when the lifting component 40 needs to move downward, the drive motor 35 drives the lifting shaft 41 to rotate in the first direction. The first transmission structure 441 is configured to transmit the power of the lifting shaft 41 rotating in the first direction to the mating component 43, thereby driving the mating component 43 to rotate in the first direction and move downward, thus allowing the lifting component 40 to rotate in the first direction and move downward simultaneously. When the lifting component 40 moves downward to the third position, the threaded locking structure 342 at the lower end of the first threaded structure 341 engages with the second threaded structure 4311. The threaded locking structure 342 restricts the mating component 43 from rotating in the first direction. At this time, the lifting component no longer moves downward, the power transmission path between the lifting shaft 41 and the mating component 43 is broken, the mating component 43 remains stationary, and the lifting shaft 41 rotates relative to the mating component 43. The rotation of the lifting shaft 41 drives the cleaning component 50 to perform cleaning work.

[0087] For example, when it is necessary to drive the lifting component 40 to move upward, the drive motor 35 drives the lifting shaft 41 to rotate in the second direction. The second transmission structure 442 is configured to transmit the power of the lifting shaft 41 rotating in the second direction to the mating component 43, thereby driving the mating component 43 to rotate in the second direction and move upward, so that the lifting component 40 can rotate in the second direction and move upward at the same time.

[0088] According to some embodiments of this utility model, refer to Figures 1-2 The first transmission structure 441 is a damping structure, and the second transmission structure 442 is a one-way bearing sleeved on the outer periphery of the lifting shaft 41. The second transmission structure 442 is connected to the mating part 43 and fixed relative to the mating part 43.

[0089] The damping structure transmits the power for the rotation of the lifting shaft 41 in the first direction to the mating part 43 through meshing or friction. By utilizing direct meshing or friction, the damping function can be achieved without additional complex mechanical devices, which helps to simplify the design, reduce costs, and reduce potential failure points.

[0090] A one-way bearing is a type of bearing that can rotate freely in one direction and is locked in another. For example, when the one-way bearing is set to rotate freely in the first direction and lock in the second direction, when the lifting shaft 41 rotates in the first direction, the one-way bearing does not restrict the lifting shaft 41 in the first direction and does not transmit power; when the lifting shaft 41 rotates in the second direction, the one-way bearing restricts the lifting shaft 41 in the second direction. At this time, the one-way bearing is tightly attached to the lifting shaft 41, and the lifting shaft 41 can drive the one-way bearing to rotate, thereby driving the mating part 43 to rotate.

[0091] For example, when it is necessary to drive the lifting component 40 to move downward, the drive motor 35 drives the lifting shaft 41 to rotate in the first direction. The second transmission structure 442 does not restrict the lifting shaft 41 in the first direction. The first transmission structure 441 transmits the rotational power of the lifting shaft 41 to the mating part 43 through meshing or friction, thereby driving the mating part 43 to rotate in the first direction and move downward, so that the lifting component 40 can rotate in the first direction and move downward at the same time. When the lifting component 40 moves downward to the third position, the threaded locking structure 342 at the lower end of the first threaded structure 341 engages with the second threaded structure 4311. The threaded locking structure 342 restricts the mating part 43 from rotating in the first direction. The restricting force of the threaded locking structure 342 on the mating part 43 in the first direction is greater than the frictional force or meshing force of the first transmission structure 441 on the mating part 43. At this time, the lifting part no longer moves downward, the power transmission path between the lifting shaft 41 and the mating part 43 is disconnected, the mating part 43 remains stationary, and the lifting shaft 41 rotates relative to the mating part 43. The rotation of the lifting shaft 41 drives the cleaning component 50 to perform cleaning work.

[0092] For example, when it is necessary to drive the lifting component 40 to move upward, the drive motor 35 drives the lifting shaft 41 to rotate in the second direction. The second transmission structure 442 has a limiting effect on the lifting shaft 41 in the second direction. At this time, the second transmission structure 442 is tightly attached to the lifting shaft 41. The lifting shaft 41 can drive the mating part 43 to rotate through the second transmission structure 442, thereby driving the mating part 43 to rotate in the second direction and move upward, so that the lifting component 40 can rotate in the second direction and move upward at the same time.

[0093] According to some embodiments of this utility model, refer to Figures 1-2 The damping structure includes a damping ring, which is sleeved on the outer periphery of the lifting shaft 41 and fixed relative to the lifting shaft 41. The damping ring is a flexible or elastic component, and it meshes with the mating component 43 or is mated by friction.

[0094] The damping ring can be made of elastic materials with high friction, such as rubber, plastic, or fiber, or other flexible materials that can mesh with the mating part 43. The damping ring drives the mating part 43 to rotate through meshing or friction.

[0095] According to some embodiments of this utility model, refer to Figures 1-2The mating part 43 includes an external threaded part 431 and a damping part 432. The external threaded part 431 is sleeved on the outer peripheral side of the lifting shaft 41 and the outer peripheral wall of the external threaded part 431 is provided with a second thread structure 4311. The damping part 432 is connected to the inner peripheral wall of the external threaded part 431. The damping ring and the second transmission structure 442 are located on both sides of the damping part 432 along the axial direction of the lifting shaft 41. For example, the damping ring is located on the upper side of the damping part 432 and the second transmission structure 442 is located on the lower side of the damping part 432. The damping part 432 meshes with the damping ring or is mated by friction.

[0096] The damping part 432 can be made of elastic materials with high friction, such as rubber, plastic, or fiber, or other flexible materials that can engage with the mating part 43. The damping part 432 drives the mating part 43 to rotate through engagement with the damping ring or friction. When the lifting shaft 41 rotates in the first direction, the mating part 43 rotates through engagement between the damping ring and the damping part 432.

[0097] According to some embodiments of this utility model, refer to Figures 1-2 The lifting component 40 also includes a clamping structure 45, which is sleeved on the outer periphery of the lifting shaft 41 and located on one axial side of the mating structure 42, for example, the clamping structure 45 is located on the lower side of the mating structure 42. The second transmission structure 442 and the damping part 432 abut against each other in the axial direction of the lifting shaft 41, and the clamping structure 45 abuts against the second transmission structure 442 in the axial direction of the lifting shaft 41. By using the clamping structure 45, the clamping structure 45 abuts against the second transmission structure 442 in the direction of the lifting shaft 41, and the second transmission structure 442 abuts against the damping part 432 in the axial direction of the lifting shaft 41. This allows the damping part 432 to be in close contact with the damping sleeve 443 provided on the lifting shaft 41, resulting in a large frictional force between the damping sleeve 443 and the damping part 432. Consequently, there is a large frictional force between the lifting shaft 41 and the mating part 43. Therefore, when the lifting shaft 41 rotates in the first direction, the mating part 43 can be driven to rotate by the frictional force between the lifting shaft 41 and the mating part 43.

[0098] For example, at least a portion of the pressing structure 45 may be an elastic structure, such that the pressing structure 45 presses the damping part 432 onto the damping sleeve 443 in the axial direction of the lifting shaft 41, thereby increasing the friction between the damping structure and the damping ring by increasing the pressure.

[0099] According to some embodiments of this utility model, refer to Figures 1-2The clamping structure 45 includes a clamping block 451 and a clamping spring 452. Both the clamping block 451 and the clamping spring 452 are sleeved on the outer periphery of the lifting shaft 41, and are arranged along the axial direction of the lifting shaft 41. For example, the clamping block 451 can be located on the upper side of the clamping spring 452. The clamping block 451 abuts against the second transmission structure 442 in the axial direction of the lifting shaft 41. One end of the clamping spring 452 abuts against or connects to the clamping block 451 in the axial direction of the lifting shaft 41, and the other end of the clamping spring 452 abuts against or connects to the lifting shaft 41.

[0100] The clamping block 451 can be loosely fitted around the outer circumference of the lifting shaft 41, and the clamping spring 452 can be in a compressed state. In this way, the clamping spring 452 can apply an axial force along the lifting shaft 41 to the clamping block 451. For example, the clamping spring 452 can apply an upward force to the clamping block 451, so that the clamping block 451 presses upward against the damping part 432, thereby applying an upward force to the damping part 432, so that the damping part 432 and the damping sleeve 443 are in close contact. Since the clamping spring 452 has elastic deformation capability in the axial direction of the lifting shaft 41, it can better make the damping part 432 and the damping sleeve 443 in close contact, thereby making the damping part 432 and the damping sleeve 443 have a large friction force, so as to drive the mating part 43 to rotate in the first direction when the lifting shaft 41 rotates in the first direction.

[0101] According to some embodiments of this utility model, refer to Figures 1-2 The drive assembly 30 includes a first transmission gear 36 and a second transmission gear 37 that mesh with each other. The first transmission gear 36 is located in the receiving cavity 32 and is sleeved on the outer periphery of the lifting shaft 41. The first transmission gear 36 is fixed relative to the lifting shaft 41. The first transmission gear 36 and the mating part 43 are arranged at intervals along the axial direction of the lifting shaft 41. The second transmission gear 37 is connected to the drive motor 35.

[0102] The second transmission gear 37 is connected to the drive motor 35, and the first transmission gear 36 meshes with the second transmission gear 37. When the drive motor 35 drives the second transmission gear 37 to rotate, the second transmission gear 37 drives the first transmission gear 36 to rotate. Since the first transmission gear 36 is fixed relative to the lifting shaft 41, the first transmission gear 36 drives the lifting shaft 41 to rotate synchronously. The first transmission gear 36 and the lifting shaft 41 rotate synchronously, or the first transmission gear 36 and the lifting shaft 41 rotate synchronously and move synchronously in the up and down direction.

[0103] It is understandable that when the lifting shaft 41 rotates and moves in the vertical direction, the first transmission gear 36 also rotates and moves in the vertical direction. The second transmission gear 37 meshes with the first transmission gear 36. The length of the transmission teeth of the second transmission gear 37 in the vertical direction can be determined according to the stroke of the first transmission gear 36 in the vertical direction, so that the first transmission gear 36 can maintain a meshing relationship with the second transmission gear 37 during the vertical movement.

[0104] The other end of the compression spring 452 abuts or connects to the first transmission gear 36 in the axial direction of the lifting shaft 41. By using the first transmission gear 36 sleeved on the lifting shaft 41 to fix or limit the other end of the compression spring 452, the structure for limiting the other end of the compression spring 452 on the lifting shaft 41 can be eliminated, thus simplifying the structure of the lifting component 40.

[0105] According to some embodiments of this utility model, refer to Figures 1-2 The guide 33 and the mounting bracket 31 are integrally molded. For example, the guide 33 and the mounting bracket 31 can be integrally injection molded. By integrally molding the guide 33 and the mounting bracket 31, the assembly process between the guide 33 and the mounting bracket 31 can be eliminated.

[0106] According to some embodiments of this utility model, refer to Figures 1-2 The lifting component 40 and the cleaning component 50 are connected and fixed by magnetic attraction. This magnetic connection makes it easier to separate or connect the cleaning component 50 and the lifting component 40 without needing to plug or unplug them, simplifying the connection method. Furthermore, the magnetic attraction reduces wear and tear caused by plugging and unplugging between the two components.

[0107] For example, when the cleaning component 50 needs to be automatically detached, the drive motor 35 can drive the lifting component 40 upwards towards the first position. The limiting structure 101 blocks the upward movement of the cleaning component 50. At this time, the magnetic attraction between the lifting component 40 and the cleaning component 50 gradually weakens. When the magnetic attraction between the lifting component 40 and the cleaning component 50 is less than the weight of the cleaning component 50, the cleaning component 50 automatically detaches from the body 10. When the cleaning component 50 needs to be installed onto the lifting component 40, the drive motor 35 can drive the lifting component 40 downwards to the second position or below, bringing the cleaning component 50 close to the lower end of the lifting component 40. Under the action of magnetic attraction, the cleaning component 50 automatically adheres and is fixed to the lower end of the lifting component 40.

[0108] According to some embodiments of this utility model, refer to Figures 1-2The lower end of the lifting component 40 is provided with a first magnetic attractor 46, and the cleaning component 50 is provided with a second magnetic attractor 55 that attracts the first magnetic attractor 46. For example, when the lifting component 40 includes the above-mentioned lifting shaft 41, the first magnetic attractor 46 is provided at the lower end of the lifting shaft 41.

[0109] At least one of the first magnetic attractor 46 and the second magnetic attractor 55 possesses magnetic attraction. For example, both the first magnetic attractor 46 and the second magnetic attractor 55 can possess magnetic attraction, and both can be permanent magnets. For example, the first magnetic attractor 46 can possess magnetic attraction, and can be a permanent magnet, while the second magnetic attractor 55 can be made of a metal material such as iron, cobalt, or nickel that can be attracted by magnetic materials. For example, the second magnetic attractor 55 can possess magnetic attraction, and can be a permanent magnet, while the first magnetic attractor 46 can be made of a metal material such as iron, cobalt, or nickel that can be attracted by magnetic materials. For example, the first magnetic attractor 46 can be an electromagnet, and the second magnetic attractor 55 can be a permanent magnet or made of a metal material such as iron, cobalt, or nickel that can be attracted by magnetic materials.

[0110] The first magnetic suction member 46 and the second magnetic suction member 55 are connected and fixed by magnetic attraction, realizing the connection between the lifting component 40 and the cleaning component 50. When the first magnetic suction member 46 and the second magnetic suction member 55 are separated, the cleaning component 50 and the lifting component 40 can be separated.

[0111] For example, when the cleaning component 50 needs to be automatically detached, the drive motor 35 can drive the lifting component 40 to move upwards towards the first position. The limiting structure 101 blocks the upward movement of the cleaning component 50. At this time, the first magnetic chuck 46 and the second magnetic chuck 55 separate from each other, and the mutual attraction between them gradually weakens. When the magnetic attraction between the first magnetic chuck 46 and the second magnetic chuck 55 is less than the weight of the cleaning component 50 itself, the cleaning component 50 separates from the lifting component 40, allowing it to automatically detach from the body 10. When the cleaning component 50 needs to be installed onto the lifting component 40, the drive motor 35 can drive the lifting component 40 to descend to the second position or below. The cleaning component 50 can be installed onto the lower end of the lifting component 40 by the mutual attraction between the first magnetic chuck 46 and the second magnetic chuck 55.

[0112] According to some embodiments of this utility model, refer to Figures 1-2 At least one of the first magnetic member 46 and the second magnetic member 55 is detachable.

[0113] The detachability of at least one of the first magnetic member 46 and the second magnetic member 55 can include the following situations: the first magnetic member 46 can be detached, the second magnetic member 55 can be detached, or both the first magnetic member 46 and the second magnetic member 55 can be detached. When the first magnetic member 46 is made of a magnetic material and the second magnetic member 55 is made of a metallic material that can be attracted by the first magnetic member 46, the first magnetic member 46 can be detached or both the first magnetic member 46 and the second magnetic member 55 can be detached; when the second magnetic member 55 is made of a magnetic material and the first magnetic member 46 is made of a metallic material that can be attracted by the second magnetic member 55, the second magnetic member 55 can be detached or both the first magnetic member 46 and the second magnetic member 55 can be detached; when both the first magnetic member 46 and the second magnetic member 55 are made of magnetic materials, both the first magnetic member 46 and the second magnetic member 55 can be detached. When the first magnetic component 46 or the second magnetic component 55 is worn or loses its magnetism, it can be replaced in a detachable manner, thereby extending the service life of the cleaning device 100.

[0114] According to some embodiments of this utility model, refer to Figures 1-2 The lower end of the lifting component 40 is provided with a connecting hole 411, which can penetrate downward through the bottom surface of the lifting component 40. For example, the connecting hole 411 can be located at the lower end of the lifting shaft 41 and penetrate through the bottom surface of the lifting shaft 41. The first magnetic attracting component 46 includes a magnetic attracting body 461 and a connecting section 462. The magnetic attracting body 461 is connected to the side of the connecting section 462 adjacent to the second magnetic attracting component 55. The connecting section 462 can be a long strip extending in the vertical direction and is inserted into the connecting hole 411.

[0115] The connecting segment 462 of the first magnetic chuck 46 is inserted into the connecting hole 411 and connected to the lifting component 40, which facilitates the installation and fixation of the first magnetic chuck 46 and the lifting component 40. For example, the connecting segment 462 of the first magnetic chuck 46 can be threaded into the connecting hole 411, or it can be fixed by providing damping material at the contact point between the first magnetic chuck 46 and the connecting hole 411. In addition, inserting the connecting segment 462 of the first magnetic chuck 46 into the connecting hole 411 on the lifting component 40 also facilitates the maintenance and replacement of the first magnetic chuck 46. For example, when the first magnetic chuck 46 needs to be replaced, the first magnetic chuck 46 can be pulled out, causing the connecting segment 462 to detach from the connecting hole 411, and then the connecting segment 462 of the new first magnetic chuck 46 can be inserted into the connecting hole 411, thus facilitating the replacement of the first magnetic chuck 46.

[0116] According to some embodiments of this utility model, refer to Figures 1-2The cleaning component 50 has a mounting groove 52, and the second magnetic component 55 is located in the mounting groove 52. By providing a mounting groove 52 in the cleaning component 50 to accommodate the second magnetic component 55, the installation and fixation of the second magnetic component 55 is facilitated, and the second magnetic component 55 can also be limited, reducing the risk of the second magnetic component 55 falling off the cleaning component 50.

[0117] The second magnetic component 55 can be fixed by snapping into the mounting groove 52 or by adhesive or other means.

[0118] According to some embodiments of this utility model, refer to Figures 1-2 A fixing bracket 54 is provided in the mounting slot 52. The fixing bracket 54 is connected to the cleaning component 50, and the second magnetic component 55 is installed in the fixing bracket 54. The second magnetic component 55 is installed in the mounting slot 52 through the fixing bracket 54, which can increase the firmness of the installation of the second magnetic component 55.

[0119] For example, in Figure 1 and Figure 2 In the example, the cleaning component 50 includes a mounting plate 51 and a cleaning element 56. The cleaning element 56 is in the form of a sheet, and the cleaning elements 56 are stacked on the bottom surface of the mounting plate 51. For example, the cleaning element 56 can be fixed to the bottom surface of the mounting plate 51 with adhesive. The mounting plate 51 has the aforementioned mounting groove 52 in the middle. The upper side of the mounting groove 52 is open, and the fixing bracket 54 can be connected to the mounting plate 51. Furthermore, the lower side of the mounting groove 52 can also be open to form a mounting opening 521 on the lower side of the mounting groove 52. A protective cover 53 can be provided at the mounting opening 521 to prevent dirt, dust, and other debris from entering the mounting groove 52 through the mounting opening 521. A clearance opening can be formed on the cleaning element 56 at the position corresponding to the mounting opening 521.

[0120] According to some embodiments of this utility model, refer to Figures 1-2 The lower end of the lifting component 40 is fitted with a guide bracket 47. The guide bracket 47 is located on the outer periphery of the first magnetic member 46 and is fixed relative to the lifting component 40. For example, the guide bracket 47 is fitted on the outer periphery of the lifting shaft 41 and is fixed relative to the lifting shaft 41. The guide bracket 47 has a guide portion 471, and the fixed bracket 54 is provided with a guide groove 541. The guide portion 471 is inserted into or disengaged from the guide groove 541 in the vertical direction.

[0121] For example, when the lifting component 40 is connected to the cleaning component 50, the guide portion 471 of the guide bracket 47 inserts into the guide groove 541 of the fixed bracket 54 in the vertical direction; when the lifting component 40 is separated from the cleaning component 50, the guide portion 471 of the guide bracket 47 disengages from the guide groove 541 of the fixed bracket 54 in the vertical direction. By providing the cooperation between the guide portion 471 of the guide bracket 47 and the guide groove 541 of the fixed bracket 54, a guiding function can be provided when the cleaning component 50 is installed onto the lifting component 40 or during the process of the cleaning component 50 gradually separating from the lifting component 40.

[0122] For example, when the cleaning component 50 needs to be automatically removed, the drive motor 35 can drive the lifting component 40 to move upward and toward the first position. The limiting structure 101 blocks the upward movement of the cleaning component 50. At this time, the first magnetic member 46 and the second magnetic member 55 separate from each other. The guide part 471 moves upward relative to the guide groove 541 and gradually separates from the guide groove 541. The mutual attraction between the first magnetic member 46 and the second magnetic member 55 gradually weakens. When the magnetic attraction between the first magnetic member 46 and the second magnetic member 55 is less than the weight of the cleaning component 50 itself, the cleaning component 50 separates from the lifting component 40, so that the cleaning component 50 can automatically fall off the body 10. When it is necessary to install the cleaning component 50 onto the lifting component 40, the drive motor 35 can drive the lifting component 40 to descend to the second position or below the second position. The cleaning component 50 can be installed onto the lower end of the lifting component 40 by mutual attraction between the first magnetic member 46 and the second magnetic member 55. During this process, by pushing the cleaning component 50 upward or by lowering the lifting component 40, the guide part 471 is gradually inserted into the guide groove 541 until it is installed in place.

[0123] Reference Figures 1-2 A cleaning system according to a second aspect embodiment of the present invention includes: a cleaning device 100 according to the first aspect embodiment of the present invention and a cleaning base station. The cleaning device 100 is adapted to cooperate with the cleaning base station, which is used to clean and / or charge the cleaning device 100.

[0124] For example, when the cleaning component 50 of the first cleaning component 20 of the cleaning device 100 needs to be cleaned, the cleaning device 100 can automatically move to the cleaning base station, and the cleaning base station can clean the cleaning component 50 of the cleaning device 100. After cleaning is completed, the cleaning device 100 can automatically leave the cleaning base station.

[0125] For example, when the cleaning device 100 needs to be charged, the cleaning device 100 can automatically move to the cleaning base station, the cleaning base station can charge the cleaning device 100, and after charging is completed, the cleaning device 100 can automatically leave the cleaning base station.

[0126] According to the cleaning system of this utility model embodiment, by setting the cleaning device 100 described above, the cleaning device 100 can realize automatic lifting and automatic disassembly of the cleaning component 50, and can simplify the drive structure of the automatic lifting and automatic disassembly function of the cleaning component 50, thereby reducing costs; by setting a cleaning base station, when the cleaning work of the cleaning device 100 is finished, the cleaning device 100 can be cleaned and / or charged through the cleaning base station.

[0127] Next, we will refer to Figures 1-2 The cleaning device 100 of some embodiments of the present invention will be described.

[0128] In this embodiment, the cleaning device 100 includes a body 10 and a first cleaning component 20. The first cleaning component 20 includes a drive component 30 and a cleaning component 50. The drive component 30 is mounted on the body 10 and includes a drive motor 35 and a lifting component 40 that can move up and down. The lifting component 40 has a first position, a second position and a third position arranged sequentially from top to bottom.

[0129] The lifting component 40 is rotatable. The drive assembly 30 includes a mounting frame 31 with a receiving cavity 32. A guide 33 is disposed within the receiving cavity 32. The drive assembly 30 also includes a first transmission gear 36 and a second transmission gear 37 that mesh with each other. The lifting component 40 includes a lifting shaft 41 and a mating structure 42. The mating structure 42 includes a mating part 43 and a transmission structure. The mating part 43 is sleeved on the outer periphery of the lifting shaft 41. The mating part 43 includes an external thread portion 431 and a damping portion 432. The external thread portion 431 is sleeved on the outer periphery of the lifting shaft 41, and the outer periphery wall of the external thread portion 431 is provided with a second thread structure 4311.

[0130] The lifting component 40 also includes a clamping structure 45, which includes a clamping block 451 and a clamping spring 452. The clamping structure 45 is sleeved on the outer periphery of the lifting shaft 41 and located on one axial side of the mating structure 42. The drive assembly 30 includes a first transmission gear 36 and a second transmission gear 37 that mesh with each other. The first transmission gear 36 is located in the receiving cavity 32 and sleeved on the outer periphery of the lifting shaft 41. The first transmission gear 36 is fixed relative to the lifting shaft 41.

[0131] The lifting component 40 and the cleaning component 50 are connected and fixed by the magnetic attraction of the first magnetic member 46 and the second magnetic member 55. The lower end of the lifting component 40 is provided with a connecting hole 411, and the connecting section 462 of the first magnetic member 46 is inserted into the connecting hole 411. The cleaning component 50 is provided with a mounting groove 52, and a fixing bracket 54 is provided in the mounting groove 52. The second magnetic member 55 is installed on the fixing bracket 54.

[0132] When the cleaning device 100 is working, the drive motor 35 drives the lifting shaft 41 to move up and down. When the lifting component 40 is in the third position, the cleaning component 50 is in contact with the working surface, and the power transmission between the lifting shaft 41 and the mating part 43 is disconnected, so that the lifting shaft 41 can rotate relative to the mating part 43, thereby achieving the function of cleaning the floor. When the lifting component 40 moves from the third position to the second position, the cleaning component 50 moves upward. When the lifting component 40 moves from the second position to the third position, the cleaning component 50 moves downward. When the lifting component 40 is in the second position, the cleaning component 50 is separated from the working surface. When the lifting component 40 moves from the second position to the first position, the limiting structure 101 blocks the upward movement of the cleaning component 50. At this time, the first magnetic suction component 46 and the second magnetic suction component 55 separate from each other, and the mutual attraction between the first magnetic suction component 46 and the second magnetic suction component 55 gradually weakens. When the magnetic attraction force is less than the weight of the cleaning component 50, the cleaning component 50 separates from the lifting component 40, thereby realizing the automatic detachment of the cleaning component 50 from the machine body 10. When the cleaning component 50 needs to be installed, the lifting component 40 can be lowered to the second position or below the second position. The cleaning component 50 can be installed to the lower end of the lifting component 40 by mutual attraction between the first magnetic component 46 and the second magnetic component 55.
