The specific structure of the cleaning robot of the present application will be described below with reference to the accompanying drawings.

The first embodiment of the present application:

as shown in fig. 1, the cleaning robot of the present embodiment includes a body 11, a floor cleaning member 12, a driving wheel 13, and a dust suction assembly (not shown). The floor cleaning component 12 and the driving wheel 13 are arranged at the bottom of the machine body 11 and are in contact with the surface to be cleaned, the floor cleaning component 12 is used for cleaning the surface to be cleaned, the driving wheel 13 is used for driving the cleaning robot to move, and the dust collection component is used for absorbing dirt on the surface to be cleaned.

As shown in fig. 1, specifically, the driving wheel 13 has a rim (not shown in the figure) and a tire (not marked in the figure) sleeved outside the rim, the surface of the tire is formed by alternately arranging convex portions and concave portions, the floor mopping piece 12 is a circular rotary floor mopping piece, and the cleaning robot is provided with two floor mopping pieces 12, and the two floor mopping pieces 12 are arranged at the bottom of the machine body 11 in the left-right direction of the cleaning robot. During the cleaning operation of the cleaning robot, the two mopping pieces 12 are in rotating contact with the surface to be cleaned, and the surface to be cleaned is mopped. As shown in fig. 2, the effective length a of the floor scrubbing member 12 in the left-right direction of the cleaning robot, i.e., the length of the floor scrubbing member 12 in the left-right direction capable of being dragged to the surface to be cleaned, is greater than the distance s between the driving wheels 13. In addition, the effective length a of the floor mopping piece 12 in the left-right direction of the machine body is not more than the maximum diameter of the machine body, so that the larger running friction resistance generated by adopting the floor mopping piece 12 with a larger size due to the improvement of the cleaning effect can be effectively reduced, the running resistance of the cleaning robot is further reduced, and the effective floor mopping area of the cleaning robot can be ensured. Meanwhile, the floor cleaning component 12 is flexibly contacted with the surface to be cleaned, for example, by using cotton, hemp, yarn, etc.

As will be understood by those skilled in the art, since the tread (especially, the concave portion of the tread) of the wheel may adhere to partial stains when the driving wheel 13 rolls on the surface to be cleaned, when the cleaning robot passes the surface to be cleaned again, the tread may cause secondary stains on the surface, and the effective length a of the floor wiping part 12 is greater than the distance s between the driving wheels, so that the effective cleaning range of the floor wiping part 12 in the left-right direction can cover the range that the driving wheel 13 travels, and during the advancing process of the cleaning robot, the floor wiping part 12 can pass the surface to be cleaned that the driving wheel 13 travels next, and then the driving wheel 13 is wiped away from the stains on the surface to be cleaned, so that the cleaning robot does not leave stains when passing the surface to be cleaned, effectively reduces the stain residue on the cleaned household floor, and improves the cleaning effect and efficiency, furthermore, the flexible contact of the mop 12 with the cleaning surface helps to reduce the frictional resistance of the mop 12 during travel, while improving the cleaning effect on the residual marks of the drive wheels 13.

In the application, the floor mopping piece 12 is in rotary contact with a tire (not marked in the figure) when the driving wheel 13 runs so as to clean the tire surface, improve the cleanness of the tire, further reduce the secondary pollution to the cleaning surface caused by the dirt attached to the tire surface in the cleaning process, and improve the cleaning effect and the cleaning efficiency of the cleaning robot.

It should be noted that the effective length a of the floor cleaning member 12 in the left-right direction of the cleaning robot may be equal to the distance s between the driving wheels 13.

As shown in fig. 1 and 3, the floor wiping member 12 has a portion extending to the outside of the body 11, including a portion extending from the side of the body 11 to the outside and a portion extending from the rear side of the body 11 to the outside, and when the cleaning robot travels along a wall, a furniture, or the like, the portion extending to the outside of the body 11 can be well attached to the wall or the furniture, and when the cleaning robot turns around at a corner, the portion extending to the outside of the body 11 can be well attached to the corner, so that the cleaning effect of the cleaning robot on the wall, the furniture, or the like is improved, and the cleaning dead angle is reduced. Taking one of the floor mopping pieces 12 as an example, the effective diameter of the floor mopping piece 12 is D (i.e. the diameter of the part of the floor mopping piece 12 capable of mopping the surface to be cleaned), the maximum length of the part of the floor mopping piece 12 extending to the outside of the machine body 11 is L, and L is set to be less than 0.5D.

As will be understood by those skilled in the art, setting L to be less than 0.5D can prevent the part of the floor mopping member 12 located outside the machine body 11 from warping during edge cleaning, which may result in the floor mopping member 12 contacting with the floor insufficiently, thus ensuring that the floor mopping member 12 maintains effective contact with the floor while cleaning edge areas such as wall edges, furniture edges, etc., and ensuring the cleaning effect of the floor mopping member 12.

As shown in fig. 1 and 4, taking one of the mopping pieces 12 as an example, during the rotation of the mopping piece 12, the edge of the mopping piece 12 abuts against the tire tread of the driving wheel 13, and at the same time, the edge of the mopping piece 12 can abut against the inner side surface of the driving wheel 13. Accordingly, the above-described structural relationship between the other floor wiping member 12 and the driving wheel 13 is also adopted, so that two floor wiping members 12 correspond to one driving wheel 13 respectively.

As can be understood by those skilled in the art, by rotating the edge of the floor mopping member 12 to contact with the tire surface of the driving wheel 13, when the cleaning robot performs a cleaning operation, the rotating floor mopping member 12 can wipe the tire surface of the driving wheel by the edge, so as to reduce the stains adhered to the tire surface of the driving wheel 13, thereby reducing the stains on the surface to be cleaned by the driving wheel 13. On the other hand, when the cleaning robot performs a cleaning operation, the edge of the floor wiping member 12 is rotated to abut against the inner side surface of the driving wheel 13, so that the rotating floor wiping member 12 can take out the filaments such as hairs entering the inner side of the driving wheel 13, and prevent the filaments such as hairs from being further wound on the driving wheel 13, thereby reducing the number of the filaments such as hairs wound on the driving wheel 13, and contributing to improvement of safety of the cleaning robot.

In addition, the diameter of the driving wheel is D, the diameter of the ground wiping part 12 is D, and the relation between D and D is set to be 2D or more and less than or equal to 2.5D, so that the running resistance caused by too much contact between the ground wiping part and the driving wheel can be prevented while the cleaning effect of the ground wiping part on the tire tread of the driving wheel is ensured.

The diameter of the floor scrubbing member 12 is referred to as the effective diameter of the floor scrubbing member.

In the application, when D is more than or equal to 2D and less than or equal to 2.5D, and the rotating speed of the ground wiping part 12 is not less than that of the driving wheel 13, the ground wiping part 12 can clean the tire tread at least once when rotating once. So, through the size ratio between the piece 12 of wiping ground and the drive wheel 13 and the setting of cooperation rotational speed size, at the in-process that drive wheel 13 marchd, guaranteed that the piece 12 of wiping ground can effectual wheel tread clean, further reduce the adhesion of dirt on the tire tread, improve the cleanliness factor of tire tread in clean process to reduce the tire and face the secondary pollution who has cleaned the surface, improved clean efficiency and clean effect.

Referring to fig. 1, a dust suction assembly of the cleaning robot includes a dust suction fan (not shown), a dirt collection box (not shown), and a dust suction port 14 formed at the bottom of a body 11, the dust suction fan is communicated with the dust suction port 14, and the dust suction fan can suck dirt on a surface to be cleaned through the dust suction port 14 and send the dirt to the dirt collection box. Further, the dust collection assembly is arranged at the front side of the floor cleaning piece 12, and the dust collection assembly and the floor cleaning piece 12 are arranged in a partially overlapped mode in a horizontal projection mode, that is, the floor cleaning piece 12 partially covers the dust collection opening 14, so that part of the edge of the floor cleaning piece 12 is located at the dust collection opening 14, when the cleaning robot performs cleaning work, on one hand, the floor cleaning piece 12 can push dirt to the dust collection opening 14, the dirt collection effect on the dirt is improved, meanwhile, the dirt cleaned by the edge of the floor cleaning piece 12 from the tire surface of the driving wheel 13 can be brought to the dust collection opening 14 and then sucked timely, on the other hand, the floor cleaning piece 12 can form a seal on the rear side of the dust collection opening 14, the suction force of the dirt collection assembly on the surface to be cleaned is improved, and the dirt absorption effect of the dirt collection assembly on the dirt can be improved.

With continued reference to fig. 1, the mop element 12 includes a mop body 121 and a cleaning element 122 disposed at the edge of the mop body 121, in other words, the cleaning element 122 is in a ring-shaped configuration and surrounds the edge of the circular mop body 121, wherein the thickness of the cleaning element 122 is greater than that of the mop body 121.

As can be understood by those skilled in the art, since the middle of the floor cleaning member 12 is under a larger pressure and the edge of the floor cleaning member is under a smaller pressure, the thickness of the cleaning member 122 at the outer edge is larger than the thickness of the inner mop body 121, so as to ensure the contact effect between the cleaning member 122 and the surface to be cleaned, thereby improving the overall cleaning effect of the floor cleaning member 12, increasing the effective area of the floor cleaning member 12, and ensuring that the effective length of the floor cleaning member 12 in the left-right direction is larger than the distance between the driving wheels 13. Moreover, as the cleaning operation of the cleaning robot proceeds, the portion of the cleaning element 122 with a large thickness is gradually compacted, and at this time, the dirt on the surface to be cleaned is mainly absorbed by the mop body 121, and the cleaning element 122 can form a relatively closed space surrounding the mop body 121, so as to prevent the dirt absorbed by the mop body 121 from being thrown away to the outside under the action of centrifugal force.

In addition, the thickness of the sweeping component 122 is greater than that of the mopping main body 121, so that the flexibility of the middle portion of the mopping component 12 is greater than that of the edge, thereby increasing the dirt bearing capacity of the mopping main body 121 and improving the cleaning effect of the mopping component 12 on the surface to be cleaned.

Further, as shown in fig. 1, the mop body 121 is provided with mop bristles 1211 and mop bristles 1212 spaced apart from each other, and the mop bristles 1211 and the mop bristles 1212 may have different hardness by using different materials or different manufacturing processes. When the scrubbing body 121 cleans a surface to be cleaned, the scrubbing bristles 1211 can scrub the surface to be cleaned to scrape off stubborn stains on the surface to be cleaned, and the scrubbing bristles 1212 can absorb liquid and dirt more easily, so that the scrubbing body 121 can deal with the stains of a multi-purpose type, and the cleaning effect of the scrubbing body 121 is improved.

Referring to fig. 1 to 4, when the cleaning robot of the present embodiment performs a cleaning operation on an uncleaned area, the cleaning robot is mainly in an advancing posture, the driving wheel 13 rolls on a surface to be cleaned to drive the cleaning robot to advance, and the driving wheel 13 first contacts the surface to be cleaned, which is not cleaned, so that some stains may be contaminated. The suction opening 14 is located at the front side of the floor scrubbing member 12 so that the suction opening 14 first sucks away some dirt from the surface to be cleaned and the rotating floor scrubbing member 12 then scrubs the surface to be cleaned. In the rotation process of the floor wiping part 12, the mopping bristles 1211 can scrape stubborn stains on the surface to be cleaned, then the mopping bristles 1212 can adsorb the stains, meanwhile, the edge of the floor wiping part 12 can also clean the tire surface of the driving wheel 13, part of the stains are swept off and are smoothly brought to the dust suction opening 14, and some stains which are not adsorbed in time can also be brought to the dust suction opening by the rotating floor wiping part 12, so that the cleaning effect is improved. In addition, when the cleaning robot moves along the sides of the wall and furniture, the floor-scrubbing member 12 extending outside the body 11 can be attached to the side of the wall or furniture, thereby cleaning the edge area. After the whole area is cleaned once, when the cleaning robot travels on the cleaned belt cleaning surface, the driving wheels 13 may leave dirt, but the effective cleaning length of the floor wiping part 12 is longer than the distance between the two driving wheels 13, so that the dirt left by the driving wheels 13 is wiped off as the cleaning robot advances, and the dirt adsorbed by the mop body 121 is blocked by the cleaning part 122, thereby effectively reducing the residual dirt on the belt cleaning surface and improving the cleaning effect of the cleaning robot.

As can be understood by those skilled in the art, the effective length a of the floor cleaning member 12 is greater than the distance s between the driving wheels, so that the floor cleaning member 12 can clean the surface to be cleaned, which is driven by the driving wheels 13 as the cleaning robot moves forward, and then the dirt left on the surface to be cleaned by the driving wheels 13 is wiped away, so that the cleaning robot does not leave any stain when passing through the surface to be cleaned, thereby effectively reducing the dirt residue on the household floor after cleaning, improving the cleaning effect and the cleaning efficiency, and the flexible contact between the floor cleaning member 12 and the cleaning surface helps to reduce friction and improve the cleaning effect on the residual marks of the driving wheels 13.

Further, by making the thickness of the cleaning piece 122 at the outer edge larger than the thickness of the inner mopping body 121, the effect of the cleaning piece 122 contacting the surface to be cleaned can be ensured, thereby improving the cleaning effect of the whole mopping piece 12 and helping to ensure that the effective length of the mopping piece 12 can be larger than the distance between the driving wheels 13.

Second embodiment of the present application:

although not shown in the drawings, the floor scrubbing member of this embodiment is a one-piece fixed mop, and has an effective length in the left-right direction of the cleaning robot greater than the distance between the driving wheels, unlike the first embodiment.

Fourth embodiment of the present application:

although not shown in the drawings, unlike the above-described embodiments, the cleaning robot of the present embodiment does not have a dust suction assembly, i.e., only has a floor mopping function.

So far, the technical solutions of the present application have been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of protection of the present application is not limited to these specific embodiments. The technical solutions in the above embodiments can be split and combined, and equivalent changes or substitutions can be made on related technical features by those skilled in the art without departing from the technical principles of the present application, and any changes, equivalents, improvements, and the like made within the technical concept and/or technical principles of the present application will fall within the protection scope of the present application.
