[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0025] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.
[0026] With the development of intelligent manufacturing and communication technologies, more and more smart home devices are serving people's lives, bringing great convenience. Cleaning devices, such as sweeping and mopping robots and floor scrubbers, can semi-automatically or automatically perform cleaning tasks such as sweeping, mopping, and washing by picking up debris on the floor.
[0027] After extensive research, the inventors of this application discovered that cleaning devices in related art are equipped with a storage box to hold the garbage swept and collected by the cleaning device and the cleaning liquid left after rinsing the surface to be cleaned. However, the sealing around the opening of the storage box is often poor, which in turn leads to poor sealing of the cleaning device, resulting in leakage of the cleaning liquid during operation, making it difficult to meet user requirements. Based on this, the present application proposes the following embodiments to address the above technical problems.
[0028] The following cleaning device embodiments of the present application describe exemplary structures of the cleaning device.
[0029] like Figure 1 and Figure 2 As shown, the cleaning device 1 includes a main frame 100 , a cleaning assembly 200 , a storage box 300 and a sealing ring 400 .
[0030] Cleaning device 1 is used for cleaning. For example, cleaning device 1 may be a mopping robot, a cleaning robot, or a floor scrubber, and may have one or more cleaning functions, such as sweeping, mopping, and scrubbing. Cleaning device 1 has a travel direction F1, which is the direction in which cleaning device 1 moves relative to the surface to be cleaned.
[0031] Alternatively, the cleaning device 1 may be a self-propelled cleaning device that can move autonomously or under command to perform cleaning operations. Alternatively, the cleaning device 1 may be a handheld cleaning device that a user holds and pushes or pulls to move the cleaning device 1 over the surface to be cleaned.
[0032] In some use scenarios, the surface to be cleaned can be the ground, that is, the cleaning device 1 is used to clean the ground. Of course, in other use scenarios, the surface to be cleaned can also be a wall, a window, a ceiling or other surfaces to be cleaned.
[0033] The main frame 100 is designed to move over the surface to be cleaned to facilitate cleaning. The cleaning assembly 200 is designed to contact the surface to be cleaned to clean it. The storage box 300 can be installed on the main frame 100 by insertion, assembly, or other methods, and is used to store garbage and dirty cleaning fluid. The sealing ring 400 is clamped between the main frame 100 and the storage box 300 to improve the sealing performance of the cleaning device 1.
[0034] Alternatively, as Figure 3 As shown, the main frame 100 is provided with a conveying inclined surface 101, a receiving cavity 102 located at the rear side of the conveying inclined surface 101, and a drop opening 103 arranged adjacent to the upper end of the conveying inclined surface 101. When the cleaning device 1 is placed on the surface to be cleaned, there is an inclination angle between the conveying inclined surface 101 and the surface to be cleaned, the side with a larger inclination angle is the front side of the conveying inclined surface 101, and the side with a smaller inclination angle is the rear side of the conveying inclined surface 101. Optionally, the main frame 100 is provided with a wheel body 110, which forms a support surface S1 for contacting the surface to be cleaned. The cleaning device 1 can be moved on the surface to be cleaned by rotating the wheel body 110. It should be noted that the support surface S1 is a virtual surface defined by the wheel body 110. For example, in some embodiments, the main frame 100 includes four wheel bodies 110, wherein the support surface S1 is a common tangent surface of the bottom ends of the four wheel bodies 110. After the cleaning device 1 is placed on the surface to be cleaned, the support surface S1 will contact or overlap with the surface to be cleaned. If the surface to be cleaned is a plane, then after the cleaning device 1 is placed on the surface to be cleaned, the support surface S1 overlaps with the surface to be cleaned. In other embodiments, there may also be three wheels 110, which is not limited here.
[0035] Alternatively, as Figure 3 As shown, the cleaning assembly 200 includes a cleaning belt 210, which is used to contact the surface to be cleaned, and the cleaning belt 210 is against the front side of the conveying slope 101 and moves relative to the conveying slope 101 to convey the garbage from the lower end of the conveying slope 101 to the upper end of the conveying slope 101.
[0036] In some embodiments, the surface of the conveying slope 101 may be formed with a concave-convex structure or a wavy striped structure to increase friction during conveying and prevent the garbage from sliding during conveying. In other embodiments, the conveying slope 101 may also be a flat surface or a curved surface with a certain curvature, or a combination of flat surfaces, a combination of flat surfaces and curved surfaces, or a combination of curved surfaces, without limitation.
[0037] By setting a conveying slope 101 and a cleaning belt 210, and making the cleaning belt 210 rest against the front side of the conveying slope 101, the cleaning belt 210 can clean the surface to be cleaned when it moves relative to the conveying slope 101, and use friction to convey the garbage from the lower end of the conveying slope 101 to the upper end of the conveying slope 101, so that it falls into the storage box 300 through the drop port 103, thereby achieving the cleaning work of the surface to be cleaned, that is, there is no need to set up a high-speed fan to suck out garbage, which is beneficial to reducing the noise and power consumption of the cleaning device 1, and effectively improving the cleaning effect and cleaning efficiency.
[0038] Alternatively, as Figures 3 to 6 As shown, the storage box 300 is detachably inserted into the accommodating cavity 102 along the travel direction F1 of the cleaning device 1. The box opening 301 of the storage box 300 is docked with the drop opening 103 to receive garbage and cleaning liquid dropped from the drop opening 103. The periphery of the drop opening 103 and the box opening 301 are respectively surrounded by a first annular table 104 and a second annular table 302, which are arranged obliquely relative to the travel direction F1 and gradually rise from the side of the box opening 301 close to the conveying inclined surface 101 to the other side away from the conveying inclined surface 101. That is, the main frame 100 is provided with a first annular table 104 inclined relative to the travel direction F1, and the storage box 300 is provided with a second annular table 302 inclined relative to the travel direction F1, and the second annular table 302 is used to abut the first annular table 104. The sealing ring 400 is clamped between the first annular table 104 and the second annular table 302. Since the first annular table 104 and the second annular table 302 are both inclined relative to the traveling direction F1 , the sealing ring 400 clamped between the first annular table 104 and the second annular table 302 is also inclined relative to the traveling direction F1 .
[0039] The storage box 300 is configured to be detachably inserted into the accommodating cavity 102 along the travel direction F1 of the cleaning device 1, so that the user can disassemble the storage box 300 to clean the garbage and cleaning liquid collected in the storage box 300, thereby improving the convenience of using the cleaning device 1.
[0040] Since the storage box 300 is inserted into the accommodating cavity 102 along the traveling direction F1, if the first annular table 104 and the second annular table 302 that clamp the sealing ring 400 are set to be perpendicular to the traveling direction F1, it is difficult to ensure the matching accuracy of the drop port 103 and the box mouth 301 during docking, and when the garbage is conveyed to the upper end of the conveying slope 101, it is easy to get stuck at the drop port 103 or the box mouth 301, resulting in the garbage being unable to fall smoothly into the storage box 300. If the first annular table 104 and the second annular table 302 are set to be parallel to the traveling direction F1, the first annular table 104 and the second annular table 302 cannot abut against each other, and thus cannot clamp the sealing ring 400, resulting in poor sealing. Therefore, compared to setting the first annular table 104 and the second annular table 302 parallel or perpendicular to the travel direction F1, the inclined first annular table 104 and the second annular table 302 are more conducive to achieving mutual contact between the first annular table 104 and the second annular table 302 when installing the storage box 300. At this time, there is a contact force between the first annular table 104 and the second annular table 302, thereby effectively clamping the sealing ring 400, effectively reducing the possibility of leakage of the cleaning liquid, and effectively improving the sealing performance of the cleaning device 1. In addition, such a setting also facilitates the docking of the drop-out port 103 and the box opening 301, which is conducive to improving the matching accuracy between the storage box 300 and the main frame 100, and is conducive to increasing the area of the drop-out port 103 and the box opening 301 while keeping the volume of the cleaning device 1 unchanged, facilitating the drop of garbage into the storage box 300, effectively reducing the possibility of garbage and cleaning liquid falling outside the storage box 300 when the cleaning device 1 is running, and improving the reliability of the cleaning work of the cleaning device 1.
[0041] Alternatively, as Figure 5 As shown, a groove 303 is provided on the second annular table 302, and the sealing ring 400 is embedded and fixed in the groove 303. By providing the groove 303 to fix the sealing ring 400, the sealing ring 400 is effectively reduced in displacement when the storage box 300 is installed, which effectively improves the sealing performance of the cleaning device 1.
[0042] Alternatively, as Figure 7 and Figure 8As shown, the sealing ring 400 includes an annular body 410 embedded in the groove 303 and at least two annular protrusions 420 protruding from the side of the annular body 410 facing the first annular table 104 and nested with each other. The at least two annular protrusions 420 are used to contact the first annular table 104. The number of annular protrusions 420 can be, for example, 2, 3, or 4, or other numbers. Specifically, at least two annular protrusions 420 are spaced apart on the side of the annular body 410 facing the first annular table 104, and one annular protrusion 420 is sleeved with another annular protrusion 420. The annular protrusions 420 are nested layer by layer, and so on until the last annular protrusion 420. The annular body 410 embedded in the groove 303 is used to achieve the installation and fixation of the sealing ring 400, and the provision of at least two annular protrusions 420 to contact the first annular table 104 is conducive to further improving the sealing performance of the sealing ring 400, effectively improving the sealing performance of the cleaning device 1, and further reducing the possibility of leakage of the cleaning liquid.
[0043] Optionally, the inclination angles of the first annular table 104 and the second annular table 302 with respect to the direction of travel F1 are between 20° and 35°, for example, 22°, 25°, 28°, 30°, 33°, etc., and of course, other values within the range are also possible. By reasonably setting the inclination angles of the first annular table 104 and the second annular table 302 with respect to the direction of travel F1, it is beneficial to increase the area of the drop opening 103 and the box opening 301 while keeping the overall volume of the cleaning device 1 unchanged, thereby facilitating the dropping of garbage into the storage box 300. In addition, the effective storage space of the storage box 300 is actually determined by the height of the box opening 301 on the side close to the conveying slope 101. When the garbage and cleaning liquid collected in the storage box 300 are too much and exceed this height, overflow will occur. If the inclination angle of the first annular table 104 and the second annular table 302 to the travel direction F1 is too large, the effective storage space of the storage box 300 will be reduced, and if the inclination angle is too small, the abutment between the first annular table 104 and the second annular table 302 will not be tight, thereby resulting in a decrease in the sealing performance of the cleaning device 1. Therefore, reasonably setting the inclination angle of the first annular table 104 and the second annular table 302 to the travel direction F1 is beneficial to improving the effective storage space of the storage box 300 while ensuring the abutment effect between the first annular table 104 and the second annular table 302, which is beneficial to improving the sealing performance and space utilization of the cleaning device 1.
[0044] Alternatively, as Figure 2 and Figure 3As shown, the cleaning device 1 also includes a filter barrel 500 with an open end. The filter barrel 500 is inserted into the storage box 300 from the box opening 301 and is used to separate garbage and cleaning liquid. The filter barrel 500 is tilted relative to the box bottom 310 in the direction from the box opening 301 to the box bottom 310 of the storage box 300 in the direction away from the conveying slope 101.
[0045] The filter barrel 500 is provided to separate garbage and cleaning liquid for the convenience of the user in cleaning, and tilting the filter barrel 500 away from the conveying slope 101 is conducive to increasing the volume of the filter barrel 500 and effectively improving the space utilization rate of the cleaning device 1.
[0046] Alternatively, as Figure 2 As shown, the filter barrel 500 includes a first side panel 510 and a second side panel 520 spaced apart along the travel direction F1, wherein the ratio of the open area to the total area of at least one of the first side panel 510 and the second side panel 520 is less than or equal to 10%. In some embodiments, the ratio of the open area to the total area of the first side panel 510 away from the conveying inclined surface 101 is less than or equal to 10%.
[0047] By reasonably setting the opening area of the first side panel 510 and the second side panel 520, the separation of garbage and cleaning liquid is achieved while shielding the shaking cleaning liquid in the storage box 300, effectively reducing the possibility of cleaning liquid spilling due to shaking during operation of the cleaning device 1, and improving the reliability of the cleaning device 1.
[0048] Alternatively, as Figure 4 and Figure 6 As shown, the first annular table 104 includes a first front side ring segment 105 close to the conveying inclined surface 101 along the travel direction F1, a first rear side ring segment 106 away from the conveying inclined surface 101 along the travel direction F1, and two first transition ring segments 107 respectively connecting the adjacent ends of the first front side ring segment 105 and the first rear side ring segment 106. The second annular table 302 includes a second front side ring segment 304 close to the conveying inclined surface 101 along the travel direction F1, a second rear side ring segment 305 away from the conveying inclined surface 101 along the travel direction F1, and two second transition ring segments 306 respectively connecting the adjacent ends of the second front side ring segment 304 and the second rear side ring segment 305. The first front side ring segment 105 and the first rear side ring segment 106 are respectively used to abut the second front side ring segment 304 and the second rear side ring segment 305, and the two first transition ring segments 107 are respectively used to abut the two second transition ring segments 306. The main frame 100 is further provided with a first guide surface 108 . The first guide surface 108 is disposed adjacent to the conveying inclined surface 101 . The first front ring segment 105 and the second front ring segment 304 are located below the first guide surface 108 .
[0049] By providing the first guide surface 108 to guide the garbage and cleaning liquid into the storage box 300, the possibility of the garbage and cleaning liquid falling out of the storage box 300 is effectively reduced, thereby improving the reliability of the cleaning operation of the cleaning device 1. In addition, by arranging the first front ring segment 105 and the second front ring segment 304 below the first guide surface 108, while facilitating the docking of the drop-out opening 103 and the box opening 301 and improving the structural compactness and space utilization of the cleaning device 1, the first guide surface 108 can block the gap between the first front ring segment 105 and the second front ring segment 304, effectively reducing the possibility of garbage and cleaning liquid accumulating in the gap, thereby reducing the maintenance difficulty of the cleaning device 1 and improving the service life of the cleaning device 1. Furthermore, since the inclination angles of the first annular table 104 and the second annular table 302 with respect to the direction of travel F1 are between 20° and 35°, the first front side ring segment 105 and the second front side ring segment 304, which are parts of the first annular table 104 and the second annular table 302 respectively, with respect to the direction of travel F1 are also between 20° and 35°. Compared with setting the first front side ring segment 105 and the second front side ring segment 304 to be vertical or approximately vertical to the direction of travel F1, the first front side ring segment 105 and the second front side ring segment 304 with reasonable inclination angles can effectively clamp the sealing ring 400 while making it difficult for garbage to accumulate and cleaning liquid to penetrate into the gap formed when the two abut against each other, thereby further reducing the maintenance difficulty of the cleaning device 1 and helping to increase the service life of the cleaning device 1.
[0050] Alternatively, as Figure 6 As shown, the main frame 100 is further provided with a second guide surface 109 . The second guide surface 109 is arranged adjacent to and away from the conveying inclined surface 101 . The first rear ring segment 106 and the second rear ring segment 305 are located at the rear side of the second guide surface 109 .
[0051] By providing the second guide surface 109 to guide the garbage and cleaning liquid into the storage box 300 , the possibility of the garbage and cleaning liquid falling out of the storage box 300 is effectively reduced, thereby improving the reliability of the cleaning work of the cleaning device 1 . In addition, by arranging the first rear side ring segment 106 and the second rear side ring segment 305 on the rear side of the first guide surface 108, it is convenient to achieve the mutual abutment of the first rear side ring segment 106 and the second rear side ring segment 305 to improve the structural integration and space utilization of the cleaning device 1, while allowing at least a portion of the first guide surface 108 to extend into the box opening 301, effectively reducing the possibility of garbage and cleaning liquid falling out of the storage box 300, and allowing the first rear side ring segment 106 and the second rear side ring segment 305 to be farther away from the box bottom 310 than the box opening 301, so that at least a portion of the storage box 300 can be arranged on the rear side of the first guide surface 108, effectively improving the storage space of the storage box 300 while reducing the possibility of the cleaning liquid inside the storage box 300 spilling due to shaking.
[0052] Alternatively, as Figure 6 As shown, the second guide surface 109 includes a straight guide surface 1091 and an arc-shaped guide surface 1092 connected to each other, the first rear side ring segment 106 and the second rear side ring segment 305 are located on the rear side of the straight guide surface 1091, and the arc-shaped guide surface 1092 is located above the straight guide surface 1091 and protrudes in the direction away from the box opening 301.
[0053] By providing a straight guide surface 1091 and a curved guide surface 1092, the garbage is effectively guided to fall into the storage box 300, and the possibility of the garbage getting stuck above the drop port 103 is effectively reduced. Compared with the surface with an angle, the straight guide surface 1091 and the curved guide surface 1092 can effectively reduce the accumulation of dirt, which is beneficial to reducing the maintenance difficulty of the cleaning device 1 and improving the service life of the cleaning device 1.
[0054] Alternatively, as Figures 2 to 4 As shown, the cleaning assembly 200 also includes a first roller 220, a second roller 230, and a connecting rod assembly 240. The connecting rod assembly 240 includes a first end 201 and a second end 202 arranged opposite each other. The first roller 220 is rotatably supported on the first end 201 of the connecting rod assembly 240 and can rotate about a first axis L1. The second roller 230 is rotatably supported on the second end 202 of the connecting rod assembly 240 and can rotate about a second axis L2 parallel to the first axis L1. The connecting rod assembly 240 is rotatably supported on the main frame 100. The cleaning belt 210 is arranged in an annular shape around the periphery of the first roller 220 and the second roller 230 and is pressed against the surface to be cleaned by the second roller 230. The travel direction F1 is perpendicular to the first axis L1 and the second axis L2. In some embodiments, the connecting rod assembly 240 can swing relative to the main frame 100 about other axes parallel to the first axis L1 and the second axis L2. In other embodiments, the connecting rod assembly 240 can swing around the first axis L1 relative to the main frame 100, that is, at this time the first roller 220 rotates around the first axis L1 relative to the connecting rod assembly 240, and the second roller 230 rotates around the second axis L2 relative to the connecting rod assembly 240. The connecting rod assembly 240 swings around the first axis L1 relative to the main frame 100, thereby driving the entire cleaning assembly 200 to swing around the first axis L1 relative to the main frame 100.
[0055] By wrapping the cleaning belt 210 around the periphery of the first roller 220 and the second roller 230, the length of the cleaning belt 210 is increased, effectively increasing the contact area between the cleaning belt 210 and the surface to be cleaned, thereby enabling the cleaning belt 210 to fully collect and transport garbage, achieving a better cleaning effect. Furthermore, by rotating the first roller 220 and the second roller 230 to achieve relative motion between the cleaning belt 210 and the conveying ramp 101, the cleaning belt 210 can use friction to carry garbage on the surface to be cleaned and, with the assistance of the conveying ramp 101, transport the garbage. This allows the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the cleaning device 1.
[0056] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
