[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Reference to "embodiment" 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 explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0025] With the development of intelligent manufacturing technology and communication technology, more and more smart home devices serve people's lives, bringing great convenience to people's lives. Cleaning devices, such as mopping robots, floor washers, etc., can semi-automatically or automatically perform cleaning tasks such as floor sweeping and mopping by picking up garbage on the ground.

[0026] After long-term research, the inventors of this application found that current cleaning devices usually have a storage box to hold the garbage cleaned and collected by the cleaning device and the dirty cleaning liquid after cleaning the surface to be cleaned. However, when the cleaning device is operating, it usually moves relative to the surface to be cleaned, which causes the cleaning liquid in the storage box to shake as the cleaning device moves. When the liquid level of the cleaning liquid is high or the shaking is relatively severe, the cleaning liquid is likely to overflow from the mouth of the storage box, resulting in spillage of the cleaning liquid and difficulty in meeting the requirements. Based on this, the following embodiments of this application are proposed to solve the above technical problems.

[0027] The following embodiments of the cleaning device of this application describe the exemplary structure of the cleaning device.

[0028] As Figure 1 and Figure 2 shown, the cleaning device 1 includes a main frame 100, a cleaning component 200, and a storage box 300.

[0029] The cleaning device 1 is used for performing cleaning work. The cleaning device 1 can be, for example, a mopping robot, a cleaning robot, or a floor washer, etc., and can have one or more cleaning functions such as floor sweeping, mopping, and floor washing. The cleaning device 1 has a traveling direction F1, and the traveling direction F1 is the direction in which the cleaning device 1 moves relative to the surface to be cleaned.

[0030] Optionally, the cleaning device 1 can be a self-propelled cleaning device that can walk autonomously or under command control, and then perform cleaning work. Optionally, the cleaning device 1 can be a hand-held cleaning device, and the user holds and pushes or pulls the cleaning device 1 to move on the surface to be cleaned.

[0031] In some usage scenarios, the surface to be cleaned can be the ground, that is, the cleaning device 1 is used for cleaning the ground. Of course, in other usage scenarios, the surface to be cleaned can also be a wall, a window, a ceiling, or other surfaces to be cleaned.

[0032] The main frame 100 is used to move on the surface to be cleaned to facilitate cleaning work on the surface to be cleaned. The cleaning component 200 is used to contact the surface to be cleaned to perform cleaning work on the surface to be cleaned. The storage box 300 can be installed on the main frame 100 by means of insertion, assembly, combination, etc., and is used to store garbage and dirty cleaning liquid.

[0033] Optionally, as Figure 3As shown, the main frame 100 is provided with a conveying inclined plane 101, a receiving cavity 102 located at the rear side of the conveying inclined plane 101, and a dropping port 103 adjacent to the upper end of the conveying inclined plane 101. The main frame 100 is provided with a wheel body 110, and the wheel body 110 forms a supporting surface S1 for contacting the surface to be cleaned. By rotating the wheel body 110, the cleaning device 1 can be moved on the surface to be cleaned. It should be noted that the supporting 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, and the supporting surface S1 is the common tangent plane of the bottoms of the four wheel bodies 110. After the cleaning device 1 is placed on the surface to be cleaned, the supporting surface S1 will contact or overlap with the surface to be cleaned. Among them, if the surface to be cleaned is a plane, then after the cleaning device 1 is placed on the surface to be cleaned, the supporting surface S1 overlaps with the surface to be cleaned. In other embodiments, it can also be three wheel bodies 110, which is not limited here. The cleaning assembly 200 includes a cleaning belt 210, and the cleaning belt 210 abuts against the front side of the conveying inclined plane 101 and moves relative to the conveying inclined plane 101 to convey the garbage from the lower end of the conveying inclined plane 101 to the upper end of the conveying inclined plane 101.

[0034] In some embodiments, the surface of the conveying inclined plane 101 may be formed with a concavo-convex structure or a wavy stripe structure to increase the friction during conveying and prevent the garbage from slipping during conveying. In other embodiments, the conveying inclined plane 101 may also be a plane or a curved surface with a certain curvature, or a combination of planes, a combination of a plane and a curved surface, or a combination of curved surfaces, which is not limited here.

[0035] By providing the conveying inclined plane 101 and the cleaning belt 210 and making the cleaning belt 210 abut against the front side of the conveying inclined plane 101, it is convenient for the cleaning belt 210 to clean the surface to be cleaned when moving relative to the conveying inclined plane 101, and use the friction to convey the garbage from the lower end of the conveying inclined plane 101 to the upper end of the conveying inclined plane 101, so as to fall into the storage box 300 through the dropping port 103, thereby realizing the cleaning work of the surface to be cleaned, that is, there is no need to set a high-speed rotating fan to suck the 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.

[0036] Optionally, as Figure 3 and Figure 4As shown, at least a part of the storage box 300 is disposed in the accommodation cavity 102 for receiving the garbage and cleaning liquid dropped from the dropping port 103. In some embodiments, only a part of the storage box 300 is disposed in the accommodation cavity 102. In other embodiments, the storage box 300 is entirely disposed in the accommodation cavity 102. The storage box 300 includes a first side wall 320 and a second side wall 330 that are spaced apart along the traveling direction F1 of the cleaning device 1, and a bottom wall 310 connected between the first side wall 320 and the second side wall 330. The first side wall 320 is closer to the transfer inclined plane 101 than the second side wall 330 and is located below the transfer inclined plane 101. The first side wall 320 is curved and protrudes toward the side away from the second side wall 330.

[0037] When the cleaning device 1 performs the cleaning work on the surface to be cleaned, the cleaning liquid will be continuously sprayed onto the cleaning belt 210, and the dirty cleaning liquid adsorbed on the cleaning belt 210 will be continuously scraped off. These dirty cleaning liquids will fall into the storage box 300 through the dropping port 103 and the box opening 301. At this time, the continuously dropping cleaning liquid will cause the liquid level of the cleaning liquid in the storage box 300 to shake. In addition, when the cleaning device 1 moves along the traveling direction F1, it will also drive the liquid level to shake. By setting the first side wall 320 of the storage box 300 close to the transfer inclined plane 101 to be curved and protrude toward the side away from the second side wall 330, a buffer and shielding are provided when the cleaning liquid shakes, so that the cleaning liquid in the storage box 300 is not easily poured out of the storage box 300 due to shaking during the operation of the cleaning device 1, effectively reducing the possibility of cleaning liquid leakage and improving the reliability of the cleaning device 1. In addition, by setting the first side wall 320 below the transfer inclined plane 101, it is beneficial to increase the internal volume of the storage box 300 without changing the volume of the cleaning device 1, which is beneficial to improving the structural compactness of the cleaning device 1 and improving the space utilization rate.

[0038] Optionally, as Figure 4 shown, the second side wall 330 is curved and protrudes toward the side away from the first side wall 320 to further reduce the possibility of cleaning liquid leakage and improve the reliability of the cleaning device 1.

[0039] Optionally, as Figure 5 shown, the ratio between the length L3 of the first side wall 320 and the length L4 of the line connecting the upper and lower ends of the first side wall 320 is between 1.2 and 1.5. By reasonably setting the first side wall 320, the possibility of the cleaning liquid pouring out of the box opening 301 of the storage box 300 can be reduced, the possibility of cleaning liquid leakage can be effectively reduced, and the reliability of the cleaning device 1 can be improved.

[0040] Optionally, as Figure 5 and Figure 6As shown, the main frame 100 is provided with an abutting surface 104 arranged opposite to the conveying inclined plane 101. The first side wall 320 includes a first wall segment 321 and a second wall segment 322 that are sequentially connected in a direction away from the bottom wall 310. The outer wall surface of the second wall segment 322 abuts against the abutting surface 104, and the radius of curvature of the first wall segment 321 is smaller than that of the second wall segment 322.

[0041] By providing the first wall segment 321 and the second wall segment 322 with different radii of curvature and abutting the outer wall surface of the second wall segment 322 against the abutting surface 104, the first side wall 320 can be accommodated below the conveying inclined plane 101, effectively utilizing the space below the conveying inclined plane 101, which is beneficial to improving the structural compactness of the cleaning device 1 and the space utilization rate.

[0042] In some embodiments, the outer wall surface of the second wall segment 322 and the abutting surface 104 are planes to better adapt to the shape of the conveying inclined plane 101, thereby more effectively utilizing the space below the conveying inclined plane 101, effectively improving the structural compactness of the cleaning device 1, and effectively increasing the space utilization rate.

[0043] Optionally, as Figure 5 shown, the ratio between the length L5 of the line connecting the upper and lower ends of the first wall segment 321 and the length L6 of the line connecting the upper and lower ends of the second wall segment 322 is between 2.7 and 3.2. By reasonably setting the first wall segment 321 and the second wall segment 322, while effectively preventing the cleaning liquid in the storage box 300 from spilling, the internal volume of the storage box 300 is increased, the structural compactness of the cleaning device 1 is effectively improved, and the space utilization rate is effectively increased.

[0044] In some embodiments, the first wall segment 321 is arranged in an arc shape, and the arc-chord ratio of the first wall segment 321 is between 1.1 and 1.3. Such a setting can reduce the possibility of the cleaning liquid spilling while increasing the internal volume of the storage box 300.

[0045] Optionally, as Figure 2 and Figure 3 shown, the cleaning device 1 further includes a filter bucket 400 with an open end. The filter bucket 400 is detachably connected to the storage box 300. Specifically, the filter bucket 400 is inserted into the storage box 300 from the box opening 301 of the storage box 300 and is used to separate garbage and cleaning liquid.

[0046] Optionally, as Figure 4As shown, the filter bucket 400 includes a first side plate 410 and a second side plate 420 that are spaced apart along the traveling direction F1, wherein the ratio of the opening area to the total area of at least one of the first side plate 410 and the second side plate 420 is less than or equal to 10%. In some embodiments, the ratio of the opening area to the total area of both the first side plate 410 and the second side plate 420 is less than 10%. In other embodiments, only the ratio of the opening area to the total area of the first side plate 410 is less than or equal to 10%.

[0047] By reasonably setting the opening areas of the first side plate 410 and the second side plate 420, while separating the garbage and the cleaning liquid, the shaking cleaning liquid in the storage box 300 is blocked, effectively reducing the possibility of the cleaning liquid spilling due to shaking during the operation of the cleaning device 1, and improving the reliability of the cleaning device 1 in working.

[0048] Optionally, as Figure 5 shown, a circular table surface 302 that is inclined with respect to the traveling direction F1 and gradually rises from the side of the box opening 301 close to the first side wall 320 to the side away from the first side wall 320 is provided around the periphery of the box opening 301. The first side plate 410 is disposed close to the second side wall 330. The distance between the first side plate 410 and the second side wall 330 is greater than the distance between the second side plate 420 and the first side wall 320. The ratio of the opening area to the total area of the first side plate 410 is less than or equal to 10%. The ratio of the opening area to the total area of the second side plate 420 is between 25% and 55%.

[0049] By setting the annular tabletop 302 surrounding the periphery of the box opening 301 to be inclined relative to the traveling direction F1 and gradually rising from the side of the box opening 301 close to the first side wall 320 to the side far from the first side wall 320, it can cooperate with the extending direction of the conveying inclined plane 101, thereby cooperating with the conveying direction of the garbage, so that the garbage is not easily stuck at the box opening 301, facilitating the garbage to smoothly fall into the storage box 300, and effectively reducing the possibility of garbage and cleaning liquid falling outside the storage box 300 when the cleaning device 1 operates. Further, since the first side plate 410 is closer to the second side wall 330, the box opening 301 and the second side plate 420 are closer to the first side wall 320, and the distance between the first side plate 410 and the second side wall 330 is greater than the distance between the second side plate 420 and the first side wall 320, the space between the first side plate 410 and the second side wall 330 is larger than the space between the second side plate 420 and the first side wall 320. Therefore, the amplitude of the cleaning liquid sloshing between the first side plate 410 and the second side wall 330 may also be larger. And due to the inclined annular tabletop 302, the side of the box opening 301 facing the first side wall 320 is inclined, and the cleaning liquid between the first side plate 410 and the second side wall 330 is likely to gush out of the storage box 300 from the unobstructed box opening 301 under the action of inertia during the sloshing process. Therefore, by making the ratio of the opening area of the first side plate 410 to the total area less than or equal to 10%, the sloshing cleaning liquid in the storage box 300 can be effectively blocked, and the possibility of cleaning liquid leakage can be effectively reduced. And by reasonably setting the opening area of the second side plate 420, the separation of garbage and cleaning liquid can be effectively achieved, avoiding the accumulation of cleaning liquid in the filter bucket 400, which is beneficial to improving the reliability of the cleaning device 1.

[0050] Optionally, as Figure 4 shown, the filter bucket 400 further includes a bottom plate 430 connected between the first side plate 410 and the second side plate 420. In some embodiments, the first side plate 410 is a solid plate without holes, and the bottom plate 430 is spaced from the bottom wall 310 of the storage box 300. In some embodiments, the ratio of the opening area of the bottom plate 430 to the total area is between 20% and 40%. In some embodiments, the first side plate 410 is a solid plate without holes, the bottom plate 430 is spaced from the bottom wall 310 of the storage box 300, and the ratio of the opening area of the bottom plate 430 to the total area is between 20% and 40%.

[0051] By setting the first side plate 410 as a solid plate to further block the sloshing cleaning liquid in the storage box 300, the possibility of the cleaning liquid spilling is effectively reduced. By setting the bottom plate 430 of the filter barrel 400 to have a certain interval from the bottom wall 310 of the storage box 300, it is convenient for the cleaning liquid to flow out of the filter barrel 400 from the bottom plate 430 and flow into the interval between the bottom wall 310 and the bottom plate 430 to better separate the garbage and the cleaning liquid. Further, when there is no interval between the bottom plate 430 of the filter barrel 400 and the bottom wall 310 of the storage box 300, the cleaning liquid flowing out of the filter barrel 400 from the second side plate 420 will be difficult to flow into the space between the first side plate 410 and the second side wall 330, resulting in the accumulation of the cleaning liquid in the space between the second side plate 420 and the first side wall 320, making the space in the storage box 300 unable to be effectively utilized and the cleaning liquid more likely to overflow. By setting the bottom plate 430 of the filter barrel 400 to have a certain interval from the bottom wall 310 of the storage box 300, the cleaning liquid can flow between the space between the second side plate 420 and the first side wall 320 and the space between the first side plate 410 and the second side wall 330 through the interval between them, avoiding the accumulation of the cleaning liquid on one side of the storage box 300 and overflowing. In addition, by reasonably setting the opening area of the bottom plate 430, the separation of garbage and cleaning liquid can be effectively realized, avoiding the accumulation of the cleaning liquid in the filter barrel 400, which is beneficial to improving the reliability of the cleaning device 1 working.

[0052] Optionally, as Figure 3 shown, the filter barrel 400 is inclined relative to the bottom wall 310 in the direction from the box opening 301 to the bottom wall 310 of the storage box 300 in a direction away from the transfer slope 101.

[0053] By setting the filter barrel 400 to separate garbage and cleaning liquid for the convenience of the user to clean up, and setting the filter barrel 400 to be inclined in a direction away from the transfer slope 101 is beneficial to increasing the volume of the filter barrel 400 and effectively improving the space utilization rate of the cleaning device 1. In addition, such a setting can make the first side plate 410 inclined relative to the bottom wall 310 in the direction from the box opening 301 to the bottom wall 310 in a direction away from the transfer slope 101, so that the cleaning liquid surging from the second side plate 420 is also difficult to flow out along the first side plate 410 towards the box opening 301, effectively reducing the possibility of the cleaning liquid spilling.

[0054] Optionally, as Figure 4As shown, the cleaning assembly 200 further 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 that are oppositely arranged. The first roller 220 is rotatably supported at 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 at 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 annularly arranged around the first roller 220 and the second roller 230, and is pressed by the second roller 230 against the surface to be cleaned. The traveling 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 another axis parallel to the first axis L1 and the second axis L2. In other embodiments, the connecting rod assembly 240 can swing relative to the main frame 100 about the first axis L1. That is, at this time, the first roller 220 rotates relative to the connecting rod assembly 240 about the first axis L1, the second roller 230 rotates relative to the connecting rod assembly 240 about the second axis L2, and the connecting rod assembly 240 swings relative to the main frame 100 about the first axis L1, thereby driving the entire cleaning assembly 200 to swing relative to the main frame 100 about the first axis L1.

[0055] By arranging the cleaning belt 210 around the first roller 220 and the second roller 230, the length of the cleaning belt 210 is increased, effectively improving the contact area between the cleaning belt 210 and the surface to be cleaned. Thus, the cleaning belt 210 can fully collect and convey garbage, and the cleaning effect is better. On the other hand, the relative movement between the cleaning belt 210 and the conveying inclined surface 101 is achieved by the rotation of the first roller 220 and the second roller 230. Thus, the cleaning belt 210 can carry the garbage on the surface to be cleaned by using the frictional force and convey the garbage with the assistance of the conveying inclined surface 101, thereby realizing the cleaning of the surface to be cleaned, which is beneficial to improving the cleaning efficiency and cleaning effect of the cleaning device 1.

[0056] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
