Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0048] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided in this disclosure. However, it will be apparent to those skilled in the art that the technical solutions provided in this disclosure can be implemented without one or more of these details.

[0049] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0050] Exemplary embodiments according to this disclosure will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that this disclosure will be thorough and complete, and that the concept of these exemplary embodiments will be fully conveyed to those skilled in the art.

[0051] As shown in Figures 1 to 13, according to an embodiment of the first aspect of this disclosure, a cleaning component 200 is provided; according to an embodiment of the second aspect of this disclosure, a cleaning module 300 is provided; and according to an embodiment of the third aspect of this disclosure, a cleaning device is provided. The cleaning component 200 is applied to the cleaning module 300, and the cleaning module 300 is applied to the cleaning device, which can be a mopping robot, a sweeping and mopping robot, a maintenance robot, or other cleaning devices that meet the requirements. For ease of description, in the following embodiments, cleaning operations and maintenance operations are collectively referred to as cleaning operations.

[0052] Specifically, cleaning equipment includes, but is not limited to, a machine body, a cleaning system, and a mobility system. These systems coordinate with each other, enabling the cleaning equipment to move autonomously to perform its cleaning function. The functional components constituting these systems are integrated within the machine body. The machine body is used to install and support other parts of the cleaning equipment. It is understood that the cleaning equipment can be a self-moving cleaning device, which is a device that automatically performs cleaning operations in a designated area without user intervention.

[0053] The cleaning system may include a wet cleaning system, in which the cleaning equipment can be a mopping robot or a maintenance robot; or the cleaning system may include both wet and dry cleaning systems, in which the cleaning equipment can be a sweeping and mopping robot, etc.

[0054] As shown in Figure 1, the wet cleaning system may include a cleaning module 300, which includes a cleaning component 200. The cleaning component 200 can be used for mopping, washing, or waxing.

[0055] Dry cleaning systems can include roller brushes, dustbins, and vacuum fans. The roller brushes, which have some contact with the ground, sweep up debris and carry it to the suction port between the roller brush and the dustbin. The suction fan then draws the debris into the dustbin with the powerful airflow generated by the dustbin.

[0056] Furthermore, the dry cleaning system may also include a side brush assembly, which is rotatably connected to the main body of the machine and is used to move debris and other contaminants outside the roller brush area into the roller brush area of ​​the cleaning system.

[0057] Further, as shown in Figure 1, the cleaning module 300 provided in this embodiment of the present disclosure also includes a lifting device 100. The lifting device 100 is connected to the cleaning component 200 and is also configured to be connected to the main body of the cleaning equipment. The lifting device 100 is configured to drive the cleaning component 200 to switch between a rising position and a falling position relative to the main body of the equipment. Thus, when the cleaning module 300 needs to work, such as when the walking surface is an area that needs mopping, washing, or waxing, the lifting device 100 drives the cleaning component 200 to the falling position, i.e., the cleaning component 200 is in the working position, allowing the cleaning component 200 to interfere with the walking surface for cleaning operations. When the cleaning module 300 does not need to work, such as when the walking surface is an area that does not need mopping, washing, or waxing, such as a carpeted area, the lifting device 100 drives the cleaning component 200 to the rising position, i.e., the cleaning component 200 is in the initial position, creating a certain distance between the cleaning component 200 and the walking surface, preventing interference and eliminating the need for cleaning operations on the walking surface. The upward direction of the cleaning component 200 is shown by arrow Z+ in Figures 1 to 3 and 8 to 13, and the downward direction of the cleaning component 200 is shown by arrow Z- in Figures 1 to 3 and 8 to 13.

[0058] In real-world applications, the cleaning components may wet or soil areas that do not require cleaning, such as carpets, due to moisture or the presence of debris. For example, debris attached to the cleaning components 200 may fall into areas that do not require mopping, washing, or waxing, causing contamination. Alternatively, because carpets have long fibers, when the cleaning equipment moves to a carpet area, there is a possibility that the carpet fibers may come into contact with the cleaning components 200 in their initial position, thereby wetting or soiling the carpet and causing contamination.

[0059] Therefore, as shown in Figures 2 and 3, according to an embodiment of the first aspect of this disclosure, a cleaning assembly 200 is provided, including: a mounting bracket 210; a cleaning element 220 connected to the mounting bracket 210; and a shielding member 230 movably disposed relative to the cleaning element 220 and switchable between a first position and a second position, wherein in the first position the shielding member 230 at least shields the bottom edge of the cleaning element 220, and in the second position the shielding member 230 at least exposes the bottom edge of the cleaning element 220.

[0060] The cleaning assembly 200 provided in this embodiment includes a mounting frame 210, a cleaning element 220, and a shielding member 230. The cleaning element 220 is connected to the mounting frame 210, which provides good support for the cleaning element 220. It is understood that the cleaning element 220 is configured to interfere with the walking surface to perform cleaning operations on the walking surface. The shielding member 230 is movably disposed relative to the cleaning element 220, and the relative positions of the shielding member 230 and the cleaning element 220 include a first position and a second position.

[0061] As shown in Figure 2, in the first position, the shielding member 230 at least shields the bottom edge of the cleaning element 220. That is, the bottom edge of the cleaning element 220 and the walking surface are separated by the shielding member 230. This reduces or prevents the cleaning component 200 from wetting or soiling areas that do not require mopping, washing, or waxing due to moisture or adhering debris. For example, debris attached to the cleaning element 220 will fall onto the shielding member 230 instead of onto the walking surface, and carpet fibers will contact the shielding member 230 instead of the cleaning element 220. This reduces the possibility of the walking surface being contaminated by the cleaning element 220, improves the cleanliness of the walking surface, enhances the overall cleaning effect of the cleaning equipment, and increases user satisfaction. The bottom edge of the cleaning element 220 can be understood as the edge of the cleaning element 220 facing the Z-direction.

[0062] As shown in Figure 3, at least the bottom edge of the cleaning element 220 is exposed in the second position shield 230, that is, there is no shield 230 between the bottom edge of the cleaning element 220 and the walking surface, and the two are opposite to each other. Thus, the need for the walking surface to be mopped, washed and waxed by the cleaning component 200 can be met. If the lifting device 100 drives the cleaning component 200 to move from the rising position to the falling position, the cleaning component 200 can be used to perform mopping, washing and waxing operations on the walking surface.

[0063] In other words, the cleaning component 200 provided in this embodiment, by providing a shielding member 230 that moves relative to the cleaning element 220 between a first position and a second position, can meet the different operational needs of the cleaning component 200 in cleaning the walking surface and in actively shielding the bottom edge of the cleaning element 220 without needing to clean the walking surface. This expands the application range of the cleaning component 200. Furthermore, when the shielding member 230 shields the bottom edge of the cleaning element 220, it separates the bottom edge of the cleaning element 220 from the walking surface, reducing the possibility of the walking surface being contaminated by the cleaning element 220 and improving the cleanliness of the walking surface. Moreover, compared to related technologies where the shielding member is mounted on the machine body to shield the cleaning element, this arrangement reduces the volume of the shielding member 230 and the space it occupies, thus saving space and meeting the design requirements of compact structure and small size for cleaning equipment, making it suitable for widespread application.

[0064] In this process, the blocking member 230 moves from the second position to the first position in the positive direction, as shown by arrow R+ in Figures 1 to 3, and moves from the first position to the second position in the reverse direction, as shown by arrow R- in Figures 1 to 3.

[0065] The cleaning element 220 is connected to the mounting bracket 210, so that the cleaning element 220 and the mounting bracket 210 can be regarded as a whole, moving with the movement of the mounting bracket 210. Specifically, the cleaning element 220 can be detachably connected to the mounting bracket 210, so as to facilitate the disassembly and separation of the cleaning element 220 and the mounting bracket 210 for maintenance or replacement, which helps to improve maintenance efficiency and save maintenance costs.

[0066] The shield 230 is movably connected to the cleaning element 220. This can be achieved by either movably connecting the shield 230 to the mounting bracket 210 so that the shield 230 can move relative to the cleaning element 220, or by movably connecting the shield 230 to the machine body so that the shield 230 can move relative to the cleaning element 220.

[0067] The shielding member 230 is movably configured relative to the cleaning element 220. This can be a rotational configuration, a translational configuration, or a combination of rotation and translation relative to the cleaning element 220. As long as the shielding member 230 is movable relative to the cleaning element 220 and can switch between the first and second positions, it can be understood as being within the scope of protection of this disclosure.

[0068] The cleaning element 220 may include a cleaning roller or a tray. The movement mode of the blocking member 230 can be reasonably set according to the different types of the cleaning element 220 so that the blocking member 230 can move relative to the cleaning element 220 and smoothly switch between the first position and the second position.

[0069] As shown in Figures 2 and 3, in some possible embodiments provided in this disclosure, the shield 230 is rotatably connected to the mounting bracket 210, and the shield 230 rotates relative to the mounting bracket 210 to switch between a first position and a second position.

[0070] In this embodiment, the shielding member 230 is switched between the first position and the second position by rotation. The rotation method helps to reduce the space occupied by the shielding member 230 during the movement. As a result, the shielding member 230, the cleaning element 220 and the mounting bracket 210 can be arranged in a compact manner, which meets the design requirements of the cleaning component 200 to be compact in structure and small in size, and is suitable for widespread application.

[0071] As shown in Figure 4, in some possible embodiments provided in this disclosure, the shielding member 230 includes a main body portion 231 and a connecting portion 232 connected to each other. The connecting portion 232 is rotatably connected to the mounting bracket 210. The length direction of the main body portion 231 is parallel to the length direction of the cleaning element 220, and the main body portion 231 is located on a portion of the periphery of the cleaning element 220. The length direction of the cleaning element 220 may be parallel to the X+ and X- directions in Figures 1 to 3.

[0072] Thus, the connecting part 232 rotates relative to the mounting bracket 210, which can drive the main body part 231 to rotate relative to the cleaning element 220 and cover the periphery of different parts of the cleaning element 220, so as to realize the switching of the shield 230 between the first position and the second position.

[0073] The length of the main body 231 can be equal to or greater than the length of the cleaning element 220, so that when the shielding member 230 is in the first position, it can cover the bottom edge of the cleaning element 220 more comprehensively, thereby reducing or avoiding the possibility of the walking surface being contaminated by the cleaning component 200 and improving the cleanliness of the walking surface.

[0074] As shown in Figure 2, in some possible embodiments provided in this disclosure, when the shielding member 230 is in the first position, the main body 231 is located below the cleaning element 220; when the shielding member 230 is in the second position, the main body 231 is located to the side of the cleaning element 220.

[0075] Normally, the cleaning element 220 is located at the bottom of the cleaning device for easy contact with the walking surface. In this embodiment, when the shielding member 230 is in the first position, the main body 231 is located below the cleaning element 220. This allows the main body 231 to shield the bottom edge of the cleaning element 220 along its length, separating the cleaning element 220 from the walking surface and providing effective shielding. Consequently, debris attached to the cleaning element 220 will fall onto the shielding member 230 under gravity, and the carpet fibers will contact the shielding member 230 without contacting the cleaning element 220. This reduces the likelihood of the walking surface being contaminated by the cleaning assembly 200 and improves the cleanliness of the walking surface.

[0076] As shown in Figure 3, when the shielding member 230 is in the second position, the main body 231 is located on the side of the cleaning element 220, thereby exposing the bottom edge of the cleaning element 220 to facilitate cleaning operations using the bottom edge of the cleaning element 220.

[0077] Furthermore, any residue that falls onto the shield 230 located below the cleaning element 220 when in the first position can continue to adhere to the shield 230 and / or fall onto the travel surface when the shield 230 moves to the second position located to the side of the cleaning element 220, so as to facilitate subsequent cleaning using the cleaning element 220.

[0078] As shown in Figures 2, 3, 4, 5 and 6, in some possible embodiments provided in this disclosure, the cleaning element 220 is a cleaning roller, and the main body 231 has an arc-shaped cross-section perpendicular to the length direction.

[0079] The cleaning roller is rotatably connected to the mounting frame 210. The cleaning roller achieves cleaning operation by rotating around its own axis and interfering with the traveling surface. Specifically, the cleaning roller is cylindrical, and its own axis is parallel to the X+ and X- directions. The cleaning roller has a small volume, which meets the compact design requirements of the cleaning assembly 200. At the same time, the cleaning roller has a low cost, which helps to save on maintenance and replacement costs.

[0080] As shown in Figures 5 and 6, the cross-section of the main body 231 perpendicular to its length direction is arc-shaped, meaning the main body 231 is entirely arc-shaped. This arc-shaped main body 231 matches the partial shape of the cleaning roller, covering a portion of its periphery. This allows the connecting part 232 to rotate relative to the mounting frame 210, and the arc-shaped main body 231 can cover different peripheries of the cleaning roller, enabling the shielding member 230 to move between a first position and a second position. This arrangement allows for a smaller distance between the main body 231 and the cleaning roller, achieving a compact layout of the shielding member 230 and the cleaning element 220, thus meeting the design requirements of a compact structure and small size for the cleaning assembly 200.

[0081] As shown in Figure 4, the connecting part 232 is located on the side of the main body. The connecting part 232 is fan-shaped, which enables the connecting part 232 to provide stable and reliable support to the main body part 231.

[0082] As shown in Figure 4, in some possible embodiments provided in this disclosure, the connecting portion 232 is located on one or both sides of the main body 231. Since the connecting portion 232 is rotatably connected to the mounting bracket 210, by having the connecting portion 232 located on one side of the main body, one side of the shielding member 230 is rotatably connected to the mounting bracket 210 via the connecting portion 232; by having the connecting portion 232 located on both sides of the main body, both sides of the shielding member 230 are rotatably connected to the mounting bracket 210 via the connecting portion 232. Thus, the needs of different structures of the shielding member 230 and different connection methods between the shielding member 230 and the mounting bracket 210 can be met.

[0083] As shown in Figure 4, one side of the shield 230 is rotatably connected to the mounting bracket 210 via the connecting part 232, which simplifies the structure of the shield 230 and the assembly operation between the shield 230 and the mounting bracket 210, thereby improving assembly efficiency and saving manufacturing costs.

[0084] The two sides of the shield 230 are rotatably connected to the mounting bracket 210 through the connecting part 232, which can improve the stability and reliability of the shield 230 relative to the mounting bracket 210 and reduce the possibility of the shield 230 shaking or coming into contact with the cleaning element 220.

[0085] Specifically, the connecting part 232 and the mounting bracket 210 can be rotatably connected by a rotating shaft.

[0086] As shown in Figures 4, 5 and 6, in some possible embodiments provided in this disclosure, the connecting part 232 is located on one side of the main body, the part of the main body 231 away from the connecting part 232 is provided with a guide part 233, the mounting bracket 210 is provided with a guide channel 211, the shape of the guide channel 211 matches the movement trajectory of the blocking member 230, the guide part 233 extends into the guide channel 211 and can move along the guide channel 211.

[0087] This embodiment discloses a method in which one side of the shielding member 230 is rotatably connected to the mounting bracket 210 via a connecting portion 232. In this embodiment, by providing a guide portion 233 on the part of the main body 231 away from the connecting portion 232, and by providing a guide channel 211 on the mounting bracket 210 that matches the movement trajectory of the main body 231, the guide portion 233 and the guide channel 211 are used for limiting and guiding. This improves the rotational accuracy of the side of the main body 231 away from the connecting portion 232 relative to the mounting bracket 210, reduces the possibility of the side of the main body 231 away from the connecting portion 232 interfering with the cleaning element 220 due to lack of support, and allows the entire main body 231 to rotate smoothly and flexibly relative to the mounting bracket 210, enabling the shielding member 230 to move smoothly and flexibly between the first position and the second position.

[0088] As shown in FIG6, in some possible embodiments provided in this disclosure, the mounting frame 210 includes a frame body 212 and a guide frame 213. The guide frame 213 is connected to the outer periphery of the frame body 212, and a guide channel 211 is formed between the guide frame 213 and the frame body 212. The blocking member 230 is located between the frame body 212 and the guide frame 213, thereby enabling the guide portion 233 on the main body portion 231 of the blocking member 230 to be located within the guide channel 211 and move along the guide channel 211.

[0089] The cleaning element 220 and the shielding element 230 are connected to the frame body 212, so that the frame body 212 provides good support for the cleaning element 220 and the shielding element 230. The bottom end of the frame body 212 is provided with a clearance opening 214 to expose the cleaning element 220, so that the bottom edge of the cleaning element 220 can be exposed outside the clearance opening 214 to avoid interference with the walking surface during cleaning operations.

[0090] In some possible embodiments provided in this disclosure, a limiting structure 234 is provided on the shield 230 and / or the mounting bracket 210, the limiting structure 234 being configured to limit the movement of the shield 230.

[0091] The setting of the limiting structure 234 can improve the accuracy of the shield 230 running to the first position and / or the second position, reduce or avoid the possibility that the shield 230 does not fully cover the bottom edge of the cleaning element 220 when it is in the first position, thus contaminating the running surface with the cleaning element 220, thereby improving the cleanliness of the running surface, and / or reduce or avoid the possibility that the shield 230 runs beyond the range relative to the cleaning element 220 and collides with the mounting bracket 210 or other components, thereby improving the reliability of the shield 230, the mounting bracket 210 or other components, and improving the overall reliability of the cleaning assembly 200.

[0092] The limiting structure 234 can be provided on the blocking member 230 to limit the movement of the blocking member 230 relative to the mounting frame 210 by cooperating with the mounting bracket 210. Alternatively, the limiting structure 234 can be provided on the mounting bracket 210 to limit the movement of the blocking member 230 relative to the mounting bracket 210 by cooperating with the blocking member 230. Alternatively, the limiting structure 234 can be provided on both the blocking member 230 and the mounting bracket 210, and the movement of the blocking member 230 relative to the mounting bracket 210 can be limited by cooperating with the limiting structure 234 on the blocking member 230. Specifically, the limiting structure 234 can be a concave part, a convex part, or a concave-convex structure, etc., and the limiting structures 234 on the blocking member 230 and the mounting bracket 210 can be the same or different.

[0093] As shown in Figures 4 and 6, in some possible embodiments provided in this disclosure, the main body 231 is provided with a limiting structure 234, which contacts the frame body 212 at the clearance opening 214 to limit the blocking member 230.

[0094] In this embodiment, by making reasonable use of the structure of the frame body 212, the frame body 212 at the clearance opening 214 comes into contact with the limiting structure 234 on the main body 231, thereby limiting the blocking member 230. This avoids or reduces the possibility that the blocking member 230 may continue to rotate in the opposite direction from the first position to the second position and collide with the mounting frame 210 or other components, thus improving the reliability of the blocking member 230, the mounting frame 210, or other components, and improving the overall reliability of the cleaning assembly 200. At the same time, this arrangement simplifies the setting of the limiting structure 234 on the frame body 212, which helps to save manufacturing costs and allows for a compact layout of the mounting frame 210 and the blocking member 230, meeting the design requirements of a compact structure and small size for the cleaning assembly 200.

[0095] As shown in Figure 6, specifically, the limiting structure 234 includes a step structure provided in the main body 231. The step structure includes a first step 235 and a second step 236. In the opposite direction, the first step 235 is located behind the second step 236. The distance between the first step 235 and the cleaning element 220 is smaller than the distance between the second step 236 and the cleaning element 220. The distance between the frame body 212 at the clearance opening 214 and the cleaning element 220 is greater than the distance between the first step 235 and the cleaning element 220. The distance between the frame body 212 at the clearance opening 214 and the cleaning element 220 is smaller than the distance between the second step 236 and the cleaning element 220. Therefore, when the shield 230 moves in the opposite direction from the first position to the second position, the second step 236 of the shield 230 will first pass through the frame body 212 at the clearance opening 214 and can pass smoothly through the frame body 212 at the clearance opening 214, while the first step 235 will contact the frame body 212 at the clearance opening 214, preventing the shield 230 from continuing to move in the opposite direction. Thus, the possibility of the shield 230 continuing to rotate in the opposite direction and colliding with the mounting frame 210 or other components and being damaged can be reduced or avoided, thereby improving the reliability of the shield 230, the mounting frame 210 or other components, and improving the overall reliability of the cleaning assembly 200.

[0096] Understandably, in other examples, the limiting structure 234 can also be other structures, such as ribs, bosses, etc.

[0097] As shown in FIG7, in some possible embodiments provided in this disclosure, the cleaning component 200 further includes: a first driving part 240 and a first transmission part 250, the first driving part 240 and the first transmission part 250 are mounted on the mounting bracket 210, the first driving part 240 is poweredly connected to the first transmission part 250, the first transmission part 250 is connected to the connecting part 232, and the first driving part 240 drives the shielding member 230 to rotate through the first transmission part 250.

[0098] In this embodiment, the first driving unit 240 drives the blocking member 230 to rotate through the first transmission unit 250. The first transmission unit 250 can adjust the output force of the first driving unit 240, thereby adjusting the rotation speed of the blocking member 230, so that the blocking member 230 can move smoothly, accurately and flexibly between the first position and the second position.

[0099] The first drive unit 240 can be driven by at least one of electric, hydraulic, or pneumatic methods. The first transmission unit 250 can be driven by at least one of a gear mechanism, a gear and rack mechanism, a chain drive, or a belt drive.

[0100] As shown in FIG7, in some possible embodiments provided in this disclosure, the first transmission unit 250 includes a gear set that meshes with each other, the gear set including a first gear 251 and a second gear, the first gear 251 being poweredly connected to the first drive unit 240, and the second gear being connected to the shield 230, or the second gear being configured as a tooth 237 formed on the shield 230.

[0101] This embodiment provides an example where the first transmission part 250 is a gear mechanism. The first transmission part 250 includes a set of meshing gears, which includes a first gear 251 and a second gear. The first gear 251 is poweredly connected to the first drive part 240. For example, the first drive part 240 can be a motor, and the first gear 251 is connected to the output shaft of the motor.

[0102] The second gear can be connected to the shield 230, thereby enabling the first drive unit 240 to operate and drive the shield 230 to rotate via the first gear 251 and the second gear of the gear set. This transmission method has a simple structure, high motion accuracy, and small size, which can meet the design requirements of the cleaning component 200 for a compact structure and small size.

[0103] As shown in Figures 4 and 7, the second gear is configured as a tooth 237 formed on the shield 230, meaning the tooth 237 of the shield 230 meshes with the first gear 251. Thus, the first drive unit 240 operates, driving the shield 230 to rotate via the first gear 251 and the tooth 237 formed on the shield 230. This transmission method is simple in structure, has high motion accuracy, and integrates the second gear and the shield 230 into a single structure, simplifying the separate second gear configuration. This further reduces the volume of the first transmission unit 250 and the cleaning assembly 200, meeting the design requirements of a compact structure and small size for the cleaning assembly 200. Simultaneously, this configuration reduces the manufacturing cost of the first transmission unit 250, making it suitable for widespread application.

[0104] As shown in Figure 7, in some possible embodiments provided in this disclosure, the gear set further includes at least one transition gear 252 located between the first gear 251 and the second gear. Thus, the power of the first drive unit 240 is transmitted to the blocking member 230 through the first gear 251, at least one transition gear 252, and the second gear, thereby driving the blocking member 230 to rotate. The arrangement of the first gear 251, the second gear, and at least one transition gear 252 can achieve speed regulation, enabling the blocking member 230 to operate smoothly at a suitable speed, thereby improving the smoothness and accuracy of the movement of the blocking member 230 between the first and second positions. Specifically, the number of transition gears 252 can be one, two, three, or more.

[0105] As shown in Figures 2 and 3, in some possible embodiments provided in this disclosure, the cleaning assembly 200 further includes: a mounting plate 260 connected to the mounting bracket 210, and a first drive unit 240 connected to the mounting plate 260. Thus, the mounting plate 260 connected to the mounting bracket 210 can provide support for the first drive unit 240, so that the first drive unit 240 can be reliably and stably fixed relative to the mounting bracket 210.

[0106] The first transmission part 250 and at least part of the connecting part 232 are located in the installation space formed between the mounting plate 260 and the mounting bracket 210, so that the mounting plate 260 and the mounting bracket 210 provide good protection for the first transmission part 250 and at least part of the connecting part 232, which helps to improve the reliability of the first transmission part 250 and the connecting part 232 and improve the overall reliability of the cleaning component 200.

[0107] Specifically, the mounting plate 260 and the mounting bracket 210 are detachably connected to facilitate the assembly and disassembly of the first transmission unit 250 and the shield 230, and to facilitate maintenance. Specifically, the mounting plate 260 and the mounting bracket 210 can be detachably connected by at least one of the following: bolt structure, snap-fit ​​structure, magnetic structure, and tenon and mortise structure.

[0108] In some possible embodiments provided in this disclosure, the cleaning assembly 200 further includes a first drive unit 240, which is poweredly connected to the shielding member 230 to drive the shielding member 230 to rotate. Thus, the first drive unit 240 operates, directly transmitting power to the shielding member 230 to drive its rotation. This transmission method allows the first drive unit 240 to directly drive the shielding member 230 to rotate, simplifying the configuration of the first transmission unit 250, which helps save costs. Simultaneously, it meets the design requirements of a compact structure and small size for the cleaning assembly 200.

[0109] In some possible embodiments provided in this disclosure, the cleaning component 200 further includes a linkage component. The cleaning component 200 is used in the cleaning module 300 of the cleaning equipment. The cleaning equipment includes a machine body, and the cleaning module 300 includes a lifting device 100 connecting the machine body and the cleaning component 200. The lifting device 100 is configured to drive the cleaning component 200 to switch between a rising position and a falling position relative to the machine body. The linkage component is poweredly connected to the lifting device 100 and drives the blocking member 230 to rotate through the linkage component. This transmission method allows the lifting device 100 to operate and drives the blocking member 230 to rotate through the linkage component, simplifying the configuration of the first drive unit, which is beneficial for cost savings. At the same time, it can meet the design requirements of the cleaning component 200 being compact and small in size.

[0110] The linkage component can be a lifting mechanism, a linkage mechanism, etc., such as a lifting structure composed of ropes and pulleys, or a four-bar linkage. It is understood that the linkage component can also be other structures, which will not be listed here.

[0111] In this system, the lifting device 100 drives the cleaning component 200 to the raised position, and the linkage component drives the blocking component 230 to rotate to the first position. Because there is a certain distance between the cleaning component 200 and the traveling surface in the raised position, the cleaning element 220 and the traveling surface will not interfere with each other. Therefore, by driving the cleaning component 200 to the raised position and simultaneously driving the blocking component 230 to rotate to the first position, the bottom edge of the cleaning element 220 is blocked, reducing the possibility of the traveling surface being contaminated by the cleaning element 220, improving the cleanliness of the traveling surface, and enhancing the overall cleaning effect of the cleaning equipment.

[0112] In this system, the lifting device 100 drives the cleaning component 200 to a lowered position, and the linkage component drives the shielding component 230 to a second position. Since the lowered position can be understood as the working position of the cleaning element 220, meaning the cleaning element 220 needs to contact the walking surface for cleaning, the lifting device 100 drives the cleaning component 200 to the lowered position. Simultaneously, the linkage component drives the shielding component 230 to rotate to the second position, exposing the bottom edge of the cleaning element 220, thus allowing the bottom edge of the cleaning element 220 to smoothly contact the walking surface for cleaning.

[0113] In some possible implementations provided in this disclosure, the cleaning component 200 further includes a detection component configured to detect that the obstruction 230 is in a first position and / or a second position.

[0114] In this embodiment, the detection component can accurately detect the position of the blocking member 230, thereby facilitating the control of the working state of the first drive unit 240 based on the detection results of the detection component, so that the blocking member 230 can accurately and smoothly move to the first position and / or the second position, so as to better achieve the blocking and exposure functions.

[0115] The detection component can detect whether the obstruction 230 is in a first position, or whether the obstruction 230 is in a second position, or whether the obstruction 230 is in both a first and a second position.

[0116] The detection component can be a position switch, such as a micro switch, a position switch, or a photoelectric switch, to achieve position detection.

[0117] The detection component can also perform detection using the odometer set in the first drive unit 240 itself. If the first drive unit 240 is a motor, the positioning detection can be achieved using the motor's own ODO (odometer). The ODO is used to record and display the total distance traveled by the first drive unit 240 since it left the factory or was last reset, thereby enabling the analysis of the rotation angle of the blocking member 230 after the last reset (such as the first position or the second position), and thus achieving positioning detection.

[0118] As shown in Figure 1, according to an embodiment of the second aspect of this disclosure, a cleaning module 300 is provided, including the cleaning component 200 of any embodiment of the first aspect. Since the cleaning module 300 includes the cleaning component 200 of any of the foregoing embodiments, it has all the technical effects of the foregoing cleaning component 200, which will not be described in detail here.

[0119] As shown in Figure 1, in some possible embodiments, the cleaning module 300 further includes a lifting device 100, with the cleaning component 200 connected to the lifting device 100. The cleaning module 300 is used for cleaning equipment, and the lifting device 100 is connected to the main body of the cleaning equipment. The lifting device 100 is configured to drive the cleaning component 200 to switch between a rising position and a falling position relative to the main body of the equipment. This satisfies the different operational needs of the cleaning component 200. For example, when the cleaning component 200 needs to work, such as when the walking surface is an area that needs mopping, washing, or waxing, the lifting device 100 drives the cleaning component 200 to a falling position, allowing the cleaning component 200 to interact with the walking surface for cleaning operations. When the cleaning component 200 does not need to work, such as when the walking surface is an area that does not need mopping, washing, or waxing, such as a carpeted area, the lifting device 100 drives the cleaning component 200 to a rising position, maintaining a certain distance between the cleaning component 200 and the walking surface, preventing interference and eliminating the need for cleaning operations on the walking surface.

[0120] It is understood that the lifting device 100 can realize the lifting and lowering of the cleaning component 200. In some examples, the lifting device 100 includes a transmission device, etc., to realize the lifting operation of the cleaning component 200. The transmission device may include, but is not limited to, the solutions mentioned below.

[0121] In some possible implementation examples provided in this disclosure, the lifting device 100 is also configured to drive the cleaning component 200 to switch between a first working position and a second working position relative to the machine body. This allows the cleaning component 200 to be moved to a working position that meets the requirements of a corresponding cleaning range, thereby satisfying the needs of different cleaning areas, expanding the cleaning range, improving cleaning effectiveness, and enhancing the user's cleaning experience.

[0122] The cleaning components 200 in the first and second working positions are located at different positions on the machine body in the horizontal direction, which can be understood as being parallel to the X+ and X- directions. Specifically, at least a portion of the cleaning component 200 in the first working position is located inside the machine body in the horizontal direction, while at least a portion of the cleaning component 200 in the second working position is located outside the machine body in the horizontal direction. The area of ​​the cleaning component 200 in the second working position located outside the machine body in the horizontal direction is larger than the area of ​​the cleaning component 200 in the first working position located outside the machine body in the horizontal direction. This allows the cleaning component 200 in the second working position to contact more of the walking surface outside the machine body, thereby increasing the cleaning range of the cleaning component 200. For example, the cleaning component 200 can handle debris in corners, reducing blind spots that cleaning equipment cannot clean in the walking surface, and reducing the possibility that the cleaning range of the cleaning component 200 is limited by the shape of the machine body, thus enabling cleaning of corner areas. Specifically, the first working position can be understood as the cleaning component 200 being in a retracted state relative to the machine body, and the second working position can be understood as the cleaning component 200 being in an extended state relative to the machine body.

[0123] In this embodiment, the lifting device 100 can realize the lifting movement of the cleaning component 200 between the rising position and the falling position, and can also realize the translational movement of the cleaning component 200 between the first working position and the second working position. Therefore, compared with the related technology that the lifting movement and translational movement of the cleaning component 200 are realized by two separate mechanisms, the structure is simplified, the cost is saved, and the design requirements of the lifting device 100 for compact structure and small size can be met.

[0124] As shown in Figures 8, 9 and 10, in some possible embodiments provided in this disclosure, the lifting device 100 includes a mounting base 110, a translation member 120 and a connecting member 130. The translation member 120 is movably disposed on the mounting base 110 and is connected to the cleaning assembly 200 through the connecting member 130. The translation member 120 is configured to move relative to the mounting base to drive the cleaning assembly 200 to move between a first working position and a second working position, as well as between a rising position and a falling position.

[0125] In this embodiment, the mounting base 110 of the lifting device 100 is connected to the machine body, and the translation member 120 of the lifting device 100 is movably disposed on the mounting base 110. The translation member 120 is connected to the cleaning component 200 through the connecting member 130. The translation member 120 moves relative to the mounting base 110 to drive the cleaning component 200 to move between a first working position and a second working position. This allows the cleaning component 200 to be moved to a working position that meets the requirements of the corresponding cleaning range, thus satisfying the needs of different cleaning ranges, expanding the cleaning range, improving the cleaning effect, and enhancing the user's cleaning experience. The translation member 120 moves relative to the mounting base 110 to drive the cleaning component 200 to move between a rising position and a falling position, satisfying the needs of the cleaning component 200 when cleaning operations are required and when cleaning operations are not required. Specifically, the cleaning component 200 includes a connecting arm 201, and the cleaning component 200 is connected to the connecting member 130 through the connecting arm 201. Specifically, the translation member 120 can be slidably disposed on the mounting base 110, or the translation member 120 can be slidably disposed on the mounting base 110.

[0126] As shown in Figures 8 and 9, in some embodiments, one end of the elastic element 140 is connected to the connecting element 130, and the other end is connected to the translation element 120. This can be understood as the connecting element 130 and the translation element 120 being connected via the elastic element 140. In this case, the mounting base 110 and the machine body can be understood as a fixed connection, meaning that the relative position of the mounting base 110 and the machine body is fixed after connection. Specifically, the mounting base 110 can be directly connected to the machine body or indirectly connected to the machine body through other components. During the movement of the cleaning assembly 200 from the first working position to the second working position along the first direction, an external force is transmitted to the connecting element 130, causing the elastic element 140 to deform. The direction of the external force is the second direction, causing the cleaning assembly 200 to move in the second direction, which is opposite to the first direction. The first direction is shown by arrow X+ in Figures 1 to 3 and Figures 8 to 13, and the second direction is shown by arrow X- in Figures 1 to 3 and Figures 8 to 13.

[0127] In other words, when the cleaning component 200 extends from the first working position to the second working position along the first direction and collides with an obstacle, it is subjected to an external force in the second direction. The deformation of the elastic element 140 provides a good buffering effect. For example, the deformation of the elastic element 140 will drive the cleaning component 200 to move in the second direction through the connecting member 130 and passively retract it. This reduces the impact of the obstacle on the cleaning component 200, the connecting member 130, the translation member 120, and the transmission part 150 and drive part mentioned later. This is beneficial to improving the reliability of the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, improve the operating accuracy of the cleaning equipment, and thus improve the cleaning effect. This arrangement allows the elastic element 140 to be placed inside the mounting base 110, which is beneficial to improving the neatness and aesthetics of the lifting device 100 and extending the service life of the elastic element 140.

[0128] As shown in Figure 10, in some embodiments, one end of the elastic member 140 is connected to the mounting base 110, and the other end is connected to the main body of the cleaning equipment. This can be understood as the mounting base 110 and the main body being connected via the elastic member 140. In this case, the relative positions of the connecting member 130 and the translation member 120 are fixed after connection. Specifically, the connecting member 130 can be directly connected to the translation member 120 or indirectly connected to the translation member 120 through other components. During the movement of the cleaning assembly 200 from the first working position to the second working position along the first direction, an external force is transmitted to the mounting base 110, causing the elastic member 140 to deform, thereby moving the cleaning assembly 200 in the second direction, which is opposite to the first direction, and the direction of the external force is the second direction.

[0129] In other words, when the cleaning component 200 extends from the first working position to the second working position along the first direction and collides with an obstacle, it is subjected to an external force in the second direction. The deformation of the elastic element 140 provides a good buffering effect. For example, the deformation of the elastic element 140 will drive the lifting device 100 to move in the second direction opposite to the first direction, thereby causing the cleaning component 200 to move in the second direction. This reduces the impact of the obstacle on the cleaning component 200, the connecting member 130, the translation member 120, and the drive unit and transmission unit 150 mentioned later. This is beneficial to improving the reliability of the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, improve the operating accuracy of the cleaning equipment, and thus improve the cleaning effect. With this arrangement, the elastic element 140 can be placed outside the mounting base 110 without changing the internal structure of the mounting base 110, which helps to save improvement costs. Similarly, the elastic element 140 can be disassembled and replaced outside the mounting base 110, which is convenient for assembly and maintenance.

[0130] Therefore, the embodiments provided in this disclosure connect different components via elastic members 140. For example, elastic member 140 connects the connecting member 130 and the translational body of the lifting device 100, or elastic member 140 connects the mounting base 110 of the lifting device 100 and the machine body of the cleaning equipment. This allows the elastic member 140 to deform and provide good buffering when the cleaning component 200, during its extension from the first working position to the second working position along the first direction, collides with an obstacle and is subjected to an external force in the second direction. This movement of the cleaning component 200 along the second direction reduces the reliability of the cleaning component 200 and the lifting device 100 in case of malfunction or damage, thus improving their reliability. Simultaneously, it reduces the possibility of the cleaning equipment shifting due to force on the cleaning component 200, improving the operating accuracy of the cleaning equipment. Furthermore, the different positions of the elastic member 140 can meet the needs of various structures of the lifting device 100, making it widely applicable.

[0131] In some possible embodiments provided in this disclosure, during the movement of the cleaning component 200 from the second working position to the first working position along the second direction, an external force is transmitted to the connector 130 or the mounting base 110 to deform the elastic member 140, thereby causing the cleaning component 200 to move in the first direction. The direction of the external force is the second direction.

[0132] In this embodiment, when the cleaning component 200 is subjected to an external force in the second direction during its retraction from the second working position to the first working position along the second direction, the deformation of the elastic element 140 will play a good buffering role. For example, the deformation of the elastic element 140 will drive the connecting element 130 or the lifting device 100 to accelerate in the second direction, thereby causing the cleaning component 200 to accelerate in the second direction and passively retract. That is, when subjected to an external force in the second direction, the retraction speed of the cleaning component 200 is greater than the retraction speed of the cleaning component 200 driven by the translation element 120. As a result, the influence of the external force on the cleaning component 200, the connecting element 130, the translation element 120, and the drive unit and transmission unit 150 mentioned later can be reduced, which is beneficial to improving the reliability of the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, improve the operating accuracy of the cleaning equipment, and ensure a good cleaning effect.

[0133] In some possible implementations provided in this disclosure, the cleaning component 200 is in a second working position when an external force is transmitted to the connector 130 or the mounting base 110 to deform the elastic member 140, thereby causing the cleaning component 200 to move in a second direction, wherein the direction of the external force is the second direction.

[0134] In this embodiment, when the cleaning component 200 is in the second working position with its extended state, the cleaning component 200 is subjected to an external force in the second direction when it collides with an obstacle. The deformation of the elastic element 140 will play a good buffering role. If the elastic element 140 deforms, it will drive the connecting element 130 or the lifting device 100 to move in the second direction, thereby causing the cleaning component 200 to passively extend and retract in the second direction. This reduces the impact of the obstacle on the cleaning component 200, the connecting element 130, the translation element 120, and the transmission part 150 and the drive part mentioned later. This is beneficial to improving the reliability of the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, and improve the operating accuracy of the cleaning equipment.

[0135] Therefore, the lifting device 100 provided in this disclosure, by setting an elastic element 140, connects the connecting element 130 and the translation element 120 using the elastic element 140, or connects the mounting base 110 and the machine body using the elastic element 140, so that when the cleaning component 200 moves from the first working position to the second working position, moves from the second working position to the first working position, or is in the second working position, after being subjected to an external force in the second direction, the deformation of the elastic element 140 can buffer the external force on the cleaning component 200, thereby improving the reliability of the cleaning component 200 and the lifting device 100, and at the same time improving the operating accuracy of the cleaning equipment and improving the overall reliability of the equipment.

[0136] As shown in Figure 8, in some possible embodiments provided in this disclosure, the elastic element 140 connects the connecting element 130 and the translating element 120. The elastic element 140 is configured to keep the connecting element 130 and the translating element 120 in a first relatively stationary position. This first relatively stationary position can be understood as the connecting element 130 and the translating element 120 moving as a whole. Therefore, the movement of the translating element 120 relative to the mounting base 110 can drive the connecting element 130 to move relative to the mounting base 110, causing the cleaning assembly 200 to move between a first working position and a second working position to meet the needs of different cleaning ranges and expand the cleaning range of the cleaning assembly 200. This transmission arrangement is simple in structure and convenient in transmission. Furthermore, the elastic element 140 is low in cost and small in size, meeting the design requirements of the lifting device 100 for low cost and compact structure.

[0137] It is understood that at least the elastic element 140 is configured to keep the connector 130 and the translator 120 in a first relatively stationary position. This can be understood as the elastic element 140 being able to keep the connector 130 and the translator 120 in a first relatively stationary position, or the elastic element 140 and other structures working together to keep the connector 130 and the translator 120 in a first relatively stationary position.

[0138] As shown in Figure 9, in some possible embodiments provided in this disclosure, the connector 130 is configured to move from a first relatively stationary position along a second direction under the action of an external force, thereby driving the cleaning component 200 to move in the second direction.

[0139] In this embodiment, when the cleaning component 200 is moved from the first working position to the second working position along the first direction and is subjected to an external force transmitted to the connector 130, the connector 130 is subjected to an external force and moves from the first relatively stationary position along the second direction. This process can cause the elastic element 140 to deform to accumulate elastic potential energy, thereby driving the cleaning component 200 to move in the second direction, reducing the impact of external force on the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, and improve the reliability and operating accuracy of the cleaning equipment.

[0140] In the above embodiment, the elastic element 140 releases elastic potential energy to drive the connector 130 to move along the first direction.

[0141] As the cleaning component 200 moves from the first working position to the second working position along the first direction, the elastic element 140 deforms due to external force, accumulating elastic potential energy. The elastic element 140 releases this elastic potential energy to drive the connecting member 130 to move along the first direction. When the external force is removed, the elastic element 140 releases its elastic potential energy to drive the connecting member 130 to move along the first direction, thus allowing the connecting member 130 to return to its first relatively stationary position under the action of the elastic element 140. Furthermore, during the release of its elastic potential energy, the elastic element 140 can push away or bounce away obstacles located in front of the cleaning component 200 along the first direction, achieving obstacle cleaning and improving the cleaning effect of the cleaning component 200. Specifically, by reasonably setting the initial length, elastic force, and deformation relationship of the elastic element 140, the elastic element 140 can, at its initial length, keep the connecting member 130 and the translation member 120 in the first relatively stationary position. Alternatively, by cooperating with other structures (such as the limiting part 160 mentioned later), the elastic element 140 is obstructed by the limiting part 160 after releasing its elastic potential energy, so that the connecting member 130 and the translation member 120 are in a first relatively stationary position.

[0142] As shown in Figure 10, in some possible embodiments provided in this disclosure, the elastic element 140 connects the mounting base 110 and the machine body, and the elastic element 140 is configured to keep the mounting base 110 and the machine body in a second relatively stationary position. This second relatively stationary position can be understood as the mounting base 110 and the machine body being able to move as a whole. Therefore, the movement of the translation member 120 relative to the mounting base 110 can drive the connecting member 130 relative to the mounting base 110, causing the cleaning component 200 to move between a first working position and a second working position to meet the needs of different cleaning ranges and expand the cleaning range of the cleaning component 200. This transmission arrangement is simple in structure and convenient in transmission. Furthermore, the elastic element 140 is low in cost and small in size, meeting the design requirements of the lifting device 100 for low cost and compact structure. Specifically, by reasonably setting the initial length, elastic force, and deformation relationship of the elastic element 140, the elastic element 140 can keep the connecting member 130 and the translation member 120 in the first relatively stationary position at its initial length. Alternatively, by cooperating with other structures, the elastic element 140 is obstructed by other structures after releasing its elastic potential energy, so that the mounting base 110 and the machine body remain in a second relatively stationary position.

[0143] It is understood that the elastic element 140 is configured to keep the mounting base 110 and the machine body in a second relatively stationary position. This can be understood as the elastic element 140 being able to keep the mounting base 110 and the machine body in a second relatively stationary position, or the elastic element 140 and other structures working together to keep the mounting base 110 and the machine body in a second relatively stationary position.

[0144] In the above embodiment, the mounting base 110 is configured to move from a second relatively static position along a second direction under the action of an external force, thereby driving the lifting device 100 to move in the second direction.

[0145] In this embodiment, when the cleaning component 200 is moved from the first working position to the second working position along the first direction and is subjected to an external force transmitted to the mounting base 110, the mounting base 110 is subjected to an external force and moves from the second relatively static position along the second direction. This process can cause the elastic element 140 to deform to accumulate elastic potential energy, thereby driving the translation element 120, the connecting element 130, and the cleaning component 200 to move synchronously in the second direction, reducing the impact of external force on the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, and improve the reliability and operating accuracy of the cleaning equipment.

[0146] In the above embodiment, the elastic element 140 releases elastic potential energy to drive the mounting base 110 to move along the first direction.

[0147] As the cleaning component 200 moves from the first working position to the second working position along the first direction, the elastic element 140 deforms due to external force, accumulating elastic potential energy. The elastic element 140 releases this elastic potential energy to drive the mounting base 110 to move along the first direction. When the external force is removed, the elastic element 140 releases its elastic potential energy to drive the mounting base 110 to move along the first direction. Thus, under the action of the elastic element 140, the mounting base 110 can return to the second relatively stationary position. Furthermore, during the release of its elastic potential energy, the elastic element 140 can push away or bounce away obstacles located near the mounting base 110 or the front of the cleaning component 200 along the first direction, achieving a cleaning operation of the obstacles and improving the cleaning effect of the cleaning component 200.

[0148] As shown in Figures 8, 9, and 10, in some possible embodiments provided in this disclosure, the lifting device 100 further includes a second drive unit and a second transmission unit 150. The second drive unit is mounted on the mounting base 110, and the second transmission unit 150 includes a meshing drive gear 151 and a rack 152. The drive gear 151 is poweredly connected to the second drive unit, and the rack 152 is connected to the translation member 120. Through the drive gear 151 and the rack 152, the translation member 120 is driven to move relative to the mounting base 110, thereby driving the cleaning component 200 to move between the first working position and the second working position. This arrangement has a simple structure, high motion accuracy, and small size, which can meet the design requirements of the lifting device 100 for a compact structure and small size.

[0149] The rack 152 and the translation component 120 can be separate structures, such as the rack 152 being mounted on the translation component 120. This arrangement facilitates the replacement and maintenance of the rack 152, thus saving maintenance costs. Alternatively, the rack 152 and the translation component 120 can be an integral structure, meaning the translation component 120 includes the rack 152. This arrangement makes the rack 152 a part of the translation component 120, simplifying the assembly operation of the translation component 120 and the rack 152, improving the assembly efficiency of the lifting device 100, and saving manufacturing costs. It is understood that in other examples, the second transmission unit 150 can also be a belt drive, chain drive, or other transmission method, which is not specifically limited in this disclosure.

[0150] As shown in Figures 8, 9, 10, and 11, in some possible embodiments provided in this disclosure, the translation member 120 is provided with a frame structure 121 at the end of the rack 152, and a guide rail 122 is provided inside the frame structure 121. The connecting member 130 is movably connected to the guide rail 122. The translation member 120 translates to guide the cleaning assembly 200 to rise and fall through the guide rail 122 and the connecting member 130. When the cleaning assembly 200 is in the first working position and the second working position, the cleaning assembly 200 is in a descending state. The cleaning assembly 200 also includes an initial position in the first working position and the rising state, which is the rising position. The first working position can be understood as the descending position.

[0151] In this embodiment, a frame structure 121 with a guide rail 122 is provided on the translation member 120, and the connecting member 130 is movably connected to the guide rail 122. The cleaning component 200 is guided to rise and fall via the guide rail 122 and the connecting member 130 through the translational movement of the translation member 120 relative to the mounting base 110. Thus, by using the second drive unit to drive the translation member 120 to perform translational movement via the second transmission unit 150, the cleaning component 200 can achieve translational movement between the first and second working positions, as well as lifting and lowering movement. Therefore, compared with related technologies that use two separate mechanisms to achieve translational and lifting movements of the cleaning component 200, the structure is simplified, costs are saved, and the design requirements of a compact structure and small size for the lifting device 100 are met. Specifically, the connecting member 130 and the guide rail 122 can be slidably connected, or the connecting member 130 and the guide rail 122 can be rollingly connected.

[0152] In this configuration, the cleaning component 200 is in the raised position, i.e., the initial position, which can be understood as the non-working position. In this position, the cleaning component 200 is raised relative to the machine body, maintaining a certain distance from the travel surface. In the first working position, the cleaning component 200 is retracted relative to the machine body, located within the area covered by the machine body. In this lowered position, the cleaning component 200 can interact with the travel surface, enabling cleaning operations on the area covered by the machine body. In the second working position, the cleaning component 200 extends relative to the machine body, with a portion of it outside the area covered by the machine body. In this lowered position, the cleaning component can interact with the travel surface, enabling cleaning operations on areas outside the machine body's coverage, thus expanding the cleaning range.

[0153] In some possible embodiments provided in this disclosure, when the cleaning component 200 moves from the second working position to the first working position following the translation member 120, the movement of the cleaning component 200 or the connector 130 along the second direction is restricted, the translation member 120 continues to translate, causing the connector 130 to move vertically from the bottom of the guide rail 122 to the top of the guide rail 122, and the connector 130 is fixedly connected to the cleaning component 200, so that the cleaning component 200 rises from the first working position to the initial position.

[0154] In other words, when the cleaning component 200 moves to the first working position, the movement of the cleaning component 200 or the connecting member 130 in the second direction is restricted. For example, the cleaning component 200 abuts against the machine body to prevent it from continuing to move in the second direction, thus preventing the connecting member 130 from continuing to move in the second direction; or, the connecting member 130 abuts against the mounting base 110 to prevent it from continuing to move in the second direction. In this state, the translation member 120 continues to move in the second direction. Since the guide rail 122 is in moving contact with the connecting member 130, the guide rail 122 can guide the cleaning component 200 to rise from the first working position to the initial position, thereby realizing the lifting operation of the cleaning component 200. Specifically, the guide rail 122 is inclined to guide the cleaning component 200 to perform lifting and lowering operations.

[0155] The cleaning component 200 is in the initial position, and the guide rail 122 and the connector 130 are in contact. Due to the weight of the cleaning component 200, the vertical component of the force acting on the connector 130 is greater than the horizontal component of the force acting on the connector 130 in the direction of inclination parallel to the guide rail 122. In this case, when the translation component 120 moves in the first direction, the connector 130 will not move with the translation component 120 under the action of the larger vertical component of the force acting on it. Instead, guided by the guide rail 122, the connector 130 will move vertically from the top of the guide rail 122 to the bottom of the guide rail 122, thereby driving the cleaning component 200 to descend from the initial position to the first working position, so as to realize the descent operation of the cleaning component 200. When the cleaning component 200 is in the first working position, the connector 130 is located at the bottom of the guide rail 122, which can also be understood as the connector 130 being detached from the guide rail 122. At this time, under the action of the cleaning component 200's own gravity, the connector 130 and the translation component 120 are relatively stationary. The translation component 120 continues to move in the first direction, driving the connector 130 to move synchronously, thereby driving the cleaning component 200 to move to the second working position, thus realizing the movement of the cleaning component 200 from the first working position to the second working position. This configuration, utilizing the translational movement of the translation component 120 in conjunction with the guide rail 122, can realize the lifting and translating operations of the cleaning component 200, with a simple structure and small size.

[0156] As shown in Figure 11, in some possible embodiments provided in this disclosure, the guide rail 122 is inclined upward along a first direction. Therefore, when the cleaning component 200 moves to the first working position, the movement of the cleaning component 200 or the connecting member 130 along the second direction is restricted, causing the translation member 120 to continue moving in the second direction. The guide rail 122, inclined upward along the first direction, cooperates with the connecting member 130 to guide the cleaning component 200 to rise. After the cleaning component 200 rises to the initial position, the translation member 120 moves along the first direction, and the guide rail 122, inclined upward along the first direction, cooperates with the connecting member 130 to guide the cleaning component 200 to descend. Thus, by reasonably setting the inclination direction of the guide rail 122 and cooperating with the translation member 120, the cleaning component 200 can be guided to rise and fall.

[0157] In some embodiments, the number of guide rails 122 is equal to the number of connectors 130, thereby ensuring that the connectors 130 can smoothly cooperate with the guide rails 122 to realize the lifting and lowering operation of the cleaning assembly 200. Specifically, the number of connectors 130 and guide rails 122 can be one, two, three, or other numbers. As shown in Figures 8, 9, and 11, there are two connectors 130 and two guide rails 122.

[0158] As shown in Figures 8 to 10, in some embodiments, the connector 130 is provided with rollers 170 for contacting the guide rail 122. The connector 130 contacts the guide rail 122 through the rollers 170. The rollers 170 improve the smoothness and flexibility of the relative movement between the connector 130 and the guide rail 122, reduce the possibility of jamming during the relative movement of the connector 130 and the guide rail 122, and thus improve the smoothness and flexibility of the lifting operation of the cleaning assembly 200. Specifically, the number of rollers 170 can be one, two, or more, and the number of rollers 170 can be reasonably set according to factors such as the size of the rollers 170, the size of the guide rail 122, and the number of guide rails 122.

[0159] As shown in Figures 8 and 9, in some possible embodiments provided in this disclosure, the translation member 120 and / or the connector 130 are provided with a limiting portion 160, and the elastic member 140 and the limiting portion 160 cooperate to keep the translation member 120 and the connector 130 in a first relatively stationary position.

[0160] In this embodiment, by utilizing the limiting portion 160 provided on the translation member 120 and / or the connecting member 130 in cooperation with the elastic member 140, the translation member 120 and the connecting member 130 can be stably maintained in the first relatively stationary position. Thus, the translation member 120 and the connecting member 130 can move as a whole, so that the translation member 120 translates and the cleaning component 200 is driven to translate through the synchronously moving connecting member 130, so as to realize the switching of the cleaning component 200 between the first working position and the second working position.

[0161] The limiting part 160 can be provided on the translation member 120, or on the connecting member 130, or simultaneously on both the translation member 120 and the connecting member 130. It is understood that the first relative static position of the translation member 120 and the connecting member 130 can be disrupted when the cleaning assembly 200 is subjected to external force. In this case, the deformation of the elastic member 140 can provide good buffering protection for the lifting device 100 and the cleaning assembly 200.

[0162] In the above embodiment, the elastic member 140 and the limiting part 160 cooperate to prevent the connecting member 130 from moving relative to the translation member 120 in the second direction from the first relatively static position, thereby making the translation member 120 and the connecting member 130 stably maintained in the first relatively static position.

[0163] In some embodiments, the elastic element 140 is located on at least one side of the rack 152, that is, the elastic element 140 can be one located on one side of the rack 152, or the elastic element 140 can be two distributed on both sides of the rack 152.

[0164] As shown in Figure 11, in some possible embodiments provided in this disclosure, a first guide groove 123 is provided in the frame structure 121. The first guide groove 123 is located between the guide rail 122 and the rack 152, and the connector 130 is configured to move along the first guide groove 123.

[0165] The first guide groove 123 provides movement space for the elastic deformation of the elastic member 140 to drive the movement of the connecting member 130 relative to the translation member 120. In other words, when the connecting member 130 is in a first relatively stationary position, and the cleaning component 200 is obstructed, causing the elastic member 140 to deform, the elastic member 140 will drive the connecting member 130 to move along the first guide groove 123 relative to the translation member 120, thus buffering the damage to the cleaning component 200 and the transmission component from external forces. Simultaneously, the bottom of the connecting member 130 is exposed through the first guide groove 123 to facilitate connection with the cleaning component 200 located at the bottom of the cleaning device. It can be understood that the movement of the connecting member 130 along the first guide groove 123 relative to the translation member 120 can drive the cleaning component 200 to translate relative to the machine body. Specifically, the connecting member 130 is configured to slide or roll along the first guide groove 123.

[0166] As shown in Figure 11, in the above embodiment, the guide rail 122 has a second guide groove 124 communicating with the first guide groove 123, and the connector 130 is configured to move along the second guide groove 124. The second guide groove 124 provides movement space for the connector 130 relative to the guide rail 122, and at the same time, exposes the bottom of the connector 130 through the second guide groove 124 to facilitate connection with the cleaning component 200 located at the bottom of the cleaning device. It can be understood that when the connector 130 is located in the second guide groove 124, the translation member 120 moves through the guide rail 122 to guide the connector 130 to rise or fall, thereby driving the cleaning component 200 to move up and down relative to the machine body in a third direction.

[0167] The connector 130 can move from the first guide groove 123 to the second guide groove 124, and the connector 130 can also move from the second guide groove 124 to the first guide groove 123, thereby causing the translation member 120 to move. This drives the cleaning assembly 200 to translate between the first working position and the second working position, to rise from the first working position to the initial position, and to descend from the output position to the first working position. Specifically, the connector 130 is configured to slide or roll along the second guide groove 124.

[0168] As shown in Figures 8 and 9, in some possible embodiments provided in this disclosure, the limiting part 160 includes a baffle 161, which is located within the frame structure 121 and configured to be movable along the frame structure 121. The baffle 161 is located behind the connector 130 in a first direction. The first end of the elastic member 140 is connected to the frame structure 121, and the second end of the elastic member 140 is connected to the baffle 161.

[0169] Since the baffle 161 along the first direction is located behind the connector 130, and the elastic member 140 connects the frame structure 121 and the baffle 161, the elastic member 140 can transmit the force to the connector 130 through the baffle 161, so that the connector 130 and the translation member 120 are kept in a first relatively stationary position. At the same time, the connector 130 can transmit the external force in the second direction to the elastic member 140 through the baffle 161, so that the elastic member 140 deforms, thereby causing the cleaning assembly 200 to move in the second direction to buffer the impact of the external force, improve the reliability of the cleaning assembly 200 and the lifting device 100, and improve the operating accuracy of the cleaning equipment. Specifically, the baffle 161 can slide along the frame structure 121, or the baffle 161 can roll along the frame structure 121.

[0170] In the above embodiments, the baffle 161 and the connector 130 are separate structures. This arrangement facilitates maintenance and replacement, and helps to save maintenance and replacement costs. It is understood that in this case, the baffle 161 and the connector 130 are in an abutting state under the action of the elastic member 140.

[0171] In the above embodiments, the baffle 161 and the connector 130 are integrated into one structure. This arrangement simplifies the assembly process and helps to improve assembly efficiency and production efficiency.

[0172] As shown in Figures 8 and 11, in some possible embodiments provided in this disclosure, the limiting part 160 further includes a first baffle 125 disposed on the inner wall of the frame structure 121 opposite to the first guide groove 123. The baffle 161 contacts the first baffle 125 to limit the relative movement of the connector 130 and the translating member 120, so that the connector 130 and the translating member 120 are held in a first relatively stationary position. Thus, by the cooperation of the baffle 161 and the first baffle 125, the reliability and stability of the connector 130 and the translating member 120 being held in the first relatively stationary position are improved, thereby improving the reliability and stability of the translational and lifting movements of the cleaning assembly 200.

[0173] Specifically, the first baffle 125 is arranged in pairs on both sides of the inner wall of the frame structure 121, so that the two sides of the baffle 161 are in contact with the first baffle 125, thereby improving the reliability and stability of the limiting.

[0174] As shown in Figures 8 and 11, in some possible embodiments provided in this disclosure, the limiting part 160 further includes a second baffle 126 disposed on the inner wall of the frame structure 121 opposite to the first guide groove 123. The second baffle 126 is located behind the first baffle 125 along the first direction. The baffle 161 contacts the second baffle 126 to limit the relative movement of the connecting member 130 and the translating member 120. Thus, by the cooperation of the baffle 161 and the second baffle 126, the movement range of the connecting member 130 relative to the translating member 120 along the second direction can be limited, reducing or avoiding the possibility that the connecting member 130 might move beyond its range relative to the translating member 120 under external force and collide with the frame structure 121, thereby providing good protection for the frame structure 121 and the connecting member 130 and improving the reliability of the lifting device 100.

[0175] Specifically, the second baffles 126 are arranged in pairs on both sides of the inner wall of the frame structure 121, so that the two sides of the baffle 161 are in contact with the second baffles 126, thereby improving the reliability and stability of the limiting.

[0176] Understandably, in some examples, the setting of the second baffle 126 can be simplified so that, under the action of external force, the connector 130 can move relative to the translation member 120 in the second direction to contact and collide with the frame structure 121. In this case, a buffer can be set on the inner wall of the frame structure 121 that may contact and collide with the connector 130 to reduce the damage caused by the collision. Specifically, the buffer can be an elastic rubber pad, a sponge pad, etc.

[0177] As shown in Figures 8, 9, and 11, in some possible embodiments provided in this disclosure, the elastic element 140 is housed within a frame structure 121. The frame structure 121 includes a first wall 127 and a second wall 128, with the first wall 127 located behind the second wall 128 along a first direction. Thus, the frame structure 121 provides good protection for the elastic element 140, which helps to improve the service life of the elastic element 140. Simultaneously, the frame structure 121 also provides good guidance for the deformation direction of the elastic element 140.

[0178] As shown in Figures 8, 9, and 11, in some examples, the elastic element 140 includes a compression spring connecting the first wall 127 and the baffle 161, i.e., both ends of the compression spring are connected to the first wall 127 and the baffle 161, respectively. The compression spring provides a stable elastic force, ensuring that the connecting element 130 and the translation element 120 are reliably and stably maintained in a first relatively stationary position, and possesses good deformation capability, allowing the cleaning assembly 200 to deform under external force during its movement along a first direction from the first working position to the second working position.

[0179] In some embodiments, the elastic element 140 includes a torsion spring, which is installed within the frame structure 121. The two torsion arms of the torsion spring are respectively connected to the first wall 127 and the baffle 161. A mounting post may be provided within the frame structure 121. The torsion spring is sleeved on the outer bearing of the mounting post, and the two torsion arms of the torsion spring are respectively connected to the first wall 127 and the baffle 161. Thus, the torsion spring can stably provide elastic force, ensuring that the connecting element 130 and the translation element 120 are reliably and stably maintained in a first relatively static position, and possessing good deformation capability so that the cleaning assembly 200 can deform under external force during movement along the first direction from the first working position to the second working position.

[0180] In some embodiments, the elastic member 140 includes a tension spring connecting the second wall 128 and the baffle 161, i.e., both ends of the tension spring are connected to the second wall 128 and the baffle 161, respectively. The tension spring provides a stable elastic force, ensuring that the connecting member 130 and the translation member 120 are reliably and stably maintained in a first relatively stationary position, and has good deformation capability so that it can deform under external force during the movement of the cleaning assembly 200 from the first working position to the second working position along the first direction.

[0181] In some possible implementations provided in this disclosure, when the elastic element 140 connects the machine body and the mounting base 110, the machine body is provided with a third guide groove, the mounting base 110 is located in the third guide groove, and configured to move within the third guide groove.

[0182] The third guide groove provides good guidance and limitation for the movement of the mounting base 110 relative to the machine body, which helps improve the movement accuracy of the mounting base 110 relative to the machine body. When the cleaning component 200 moves from the first working position to the second working position along the first direction, the elastic element 140 deforms due to external force. The mounting base 110 then moves accurately along the third guide groove relative to the machine body to drive the cleaning component 200 to move along the second direction. This reduces the damage caused by external force and lowers the reliability of the cleaning component 200 and the lifting device 100 in case of failure or damage. At the same time, it reduces the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, improves the reliability of the cleaning component 200 and the lifting device 100, and improves the operating accuracy of the cleaning equipment.

[0183] As shown in Figure 12, in some possible embodiments provided in this disclosure, the mounting base 110 is provided with a slide groove 111, and the translation member 120 is located within the slide groove 111 and configured to move along the slide groove 111. The slide groove 111 provides good guidance and limiting, which can improve the movement accuracy of the translation member 120 relative to the mounting base 110, thereby improving the movement accuracy of the cleaning assembly 200. It also limits the operating range of the translation member 120 relative to the mounting base 110, avoiding the possibility that the translation member 120 may move beyond the operating range relative to the mounting base 110 and damage other components, thus improving the reliability of the lifting device 100.

[0184] The bottom of the chute 111 has a clearance channel 112, and the connector 130 is exposed within the clearance channel 112. The cleaning component 200 passes through the clearance channel 112 and connects with the connector 130. The clearance channel 112 allows the cleaning component 200 to connect smoothly with the connector 130 and be located at the bottom of the device body. Furthermore, the clearance channel 112 allows the cleaning component 200 to move smoothly between the first working position and the second working position along with the connector 130.

[0185] As shown in Figure 13, in some possible embodiments provided in this disclosure, the lifting device 100 further includes a cover plate 180, which is connected to the mounting base 110. The translation member 120 and the connecting member 130 are located within the installation space enclosed by the cover plate 180 and the mounting base 110. Thus, the cover plate 180 provides good protection for the translation member 120 and the connecting member 130, thereby extending their service life.

[0186] The second transmission unit 150 is located within the installation space, so that the cover plate 180 and the mounting base 110 can provide good protection for the second transmission unit 150.

[0187] When the elastic element 140 is connected to the translation element 120 and the connecting element 130, the elastic element 140 is located in the installation space so that the cover plate 180 and the mounting base 110 can provide good protection for the elastic element 140.

[0188] When the elastic element 140 connects the machine body and the mounting base 110, the elastic element 140 is located outside the mounting space to facilitate connection with the machine body.

[0189] The length of the cover plate 180 is less than the length of the mounting base 110, and the length of the cover plate 180 is greater than the length of the translation component 120. This allows the cover plate 180 to cover part of the opening of the slide groove 111 of the mounting base 110, while part of the translation component 120 is not covered by the cover plate 180 and is exposed to the outside, making it easy to know the position of the translation component 120. This is convenient for the detection device to detect the position of the translation component 120, or for the user to visually observe the position of the translation component 120.

[0190] The cover plate 180 is provided with an observation port 181 for exposing the translation component 120, so as to make it easy to know the position of the translation component 120, such as to facilitate the detection device to detect the position of the translation component 120, or to make it easy for the user to observe the position of the translation component 120.

[0191] Specifically, the cover plate 180 and the mounting base 110 are detachably connected to facilitate the disassembly and assembly of components within the installation space, making maintenance and replacement easier. Specifically, the cover plate 180 and the mounting base 110 can be detachably connected in at least one of the following ways: bolt structure, snap-fit ​​structure, plug-in structure, tenon and mortise structure, or magnetic structure.

[0192] According to an embodiment of the third aspect of this disclosure, a cleaning device is provided, comprising a machine body and a cleaning module 300 of any of the foregoing embodiments. Since the cleaning device includes the cleaning module 300 of any of the foregoing embodiments, it possesses all the technical effects of the aforementioned cleaning module 300, which will not be elaborated upon here.

[0193] According to the cleaning component, cleaning module, and cleaning equipment provided in this disclosure, the cleaning component includes a mounting frame, a cleaning element, and a shielding member. The cleaning element is connected to the mounting frame, and the shielding member is movably disposed relative to the cleaning element. The shielding member moves between a first position and a second position relative to the cleaning element. In the first position, the shielding member at least covers the bottom edge of the cleaning element, and in the second position, the shielding member at least exposes the bottom edge of the cleaning element. This satisfies the different operational needs of the cleaning component—performing cleaning operations on the running surface and actively shielding the bottom edge of the cleaning element without requiring cleaning operations on the running surface—expanding the application range of the cleaning component. Simultaneously, when the shielding member shields the bottom edge of the cleaning element, the possibility of the running surface being contaminated by the cleaning element is reduced, improving the cleanliness of the running surface. Furthermore, compared to related technologies where the shielding member is mounted on the machine body to shield the cleaning element, this arrangement reduces the volume of the shielding member and the space it occupies, thus saving space and meeting the design requirements of a compact and small-sized cleaning equipment, making it suitable for widespread application.

[0194] This disclosure has been described through the above embodiments; however, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this disclosure to the described embodiments. Furthermore, those skilled in the art will understand that this disclosure is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of this disclosure, all of which fall within the scope of protection claimed by this disclosure. The scope of protection of this disclosure is defined by the appended claims and their equivalents.
