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

As shown in fig. 1, the cleaning robot of the present embodiment includes a body 11, a floor wiping member 12, a driving wheel 13, an edge brush 15, and a dust suction assembly (not shown). The floor cleaning component 12, the side brush 15 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 mopping the surface to be cleaned, the side brush 15 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. Meanwhile, the floor cleaning component 12 is flexibly contacted with the surface to be cleaned, for example, by using cotton, hemp, yarn, etc.

It can be understood by those skilled in the art that since the tire tread (especially, the concave portion of the tire tread) may be partially contaminated when the driving wheel 13 rolls on the surface to be cleaned, the tire tread may cause secondary contamination to the surface when the cleaning robot passes the surface to be cleaned again, and by making the effective length a of the floor wiping part 12 longer than the distance s between the driving wheels, the effective cleaning range of the floor wiping part 12 in the left and right directions can cover the range that the driving wheel 13 travels, the floor wiping part 12 can immediately pass the surface to be cleaned that the driving wheel 13 travels over during the travel of the cleaning robot, and then the dirt of the driving wheel 13 remaining on the surface to be cleaned is wiped away, so that the cleaning robot does not leave a stain when passing 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 floor wiping part 12 rotatably contacts the tire (not marked in the drawing) while the driving wheel 13 travels, to clean the tire, and further reducing the dirt attached to the tire tread during the cleaning, and improving the cleaning effect and the cleaning efficiency of the cleaning robot.

In the present application, the flexible contact of the floor scrubbing member 12 with the cleaning surface helps to reduce the frictional resistance of the floor scrubbing member 12 during travel, while improving the cleaning effect on the residual marks of the drive wheel 13.

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

As shown in fig. 1 and 4, taking one of the mopping members 12 as an example, during the rotation of the mopping member 12, the mopping member 12 is in rotational contact with the tire of the driving wheel 13, and accordingly, the other mopping member 12 and the driving wheel 13 also adopt the above-mentioned structural relationship, so that two mopping members 12 respectively correspond to one driving wheel 13.

In addition, the outer diameter of the driving wheel 13 is D, the effective diameter of the ground wiping part 12 is D, the relation between D and D is set to be 1.5D or more and less than or equal to D and 2.5D, and the rotating speed of the ground wiping part 12 is not less than the rotating speed of the driving wheel 13, so that the tire tread can be cleaned at least once when the ground wiping part 12 rotates for one circle. So, through the size proportion 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 reduced the adhesion of dirt on the tire tread, improved the cleanliness factor of tire tread in clean process to reduce the tire and face the secondary pollution who cleans the surface, improved clean efficiency and clean effect.

Further, the floor wiping member 12 is in rotational contact with the inner side of the tire. As can be understood by those skilled in the art, by making the floor mopping member 12 rotate to contact the inner side surface of the tire tread of the driving wheel 13, when the cleaning robot performs a cleaning operation, the rotating floor mopping member 12 can wipe the inner side surface of the tire of the driving wheel by using an edge, the cleaning area of the tire by the floor mopping member 12 is further increased, the adhesion of dirt to the inner side surface of the tire is reduced, and filaments such as hair and the like are prevented from winding on the driving wheel 12 along with the rotation of the driving wheel 12, so that the filaments such as hair and the like wound on the driving wheel 12 are reduced, which is helpful for improving the safety of the cleaning robot.

In addition, the maximum length of the part of the ground cleaning piece 12 which is in rotary contact with the inner side surface of the tire is b, the outer diameter of the driving wheel 13 is d, d is not less than 7b and not more than 35b, and therefore the running resistance caused by excessive contact between the ground cleaning piece 12 and the driving wheel 13 can be prevented while the tire cleaning effect on the driving wheel 13 is ensured.

The inner side of the tire in the present application means the side close to the dust suction port 14 at the bottom of the machine body 11.

As shown in fig. 1 and 3, the floor mopping unit 12 has a portion extending to the outside of the body 11, wherein the portion extending from the side of the body 11 and the portion extending from the rear side of the body 11 are included, when the cleaning robot moves along the wall, furniture, etc., the portion extending to the outside of the body 11 can be well attached to the wall or furniture, and when the cleaning robot turns around the wall, the portion extending to the outside of the body 11 can be well attached to the wall, so that the cleaning effect of the cleaning robot on the wall, furniture, etc. edge area and wall can be improved, and the cleaning dead angle can be 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 not contacting the floor tightly enough, so as to ensure that the floor mopping member 12 keeps effective contact with the floor while cleaning edge areas such as wall edges and furniture edges, and ensure the cleaning effect of the floor mopping member 12.

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 mopping piece 12, and the dust collection assembly and the floor mopping piece 12 are arranged in a partially overlapped manner in a horizontal projection, that is, the floor mopping piece 12 partially covers the dust collection opening 14, so that part of the edge of the floor mopping piece 12 is positioned at the dust collection opening 14, when the cleaning robot performs cleaning work, on one hand, the floor mopping piece 12 can push dirt towards the dust collection opening 14, the dirt collection effect on the dirt is improved, and meanwhile, the dirt cleaned off from the tire surface of the driving wheel 13 at the edge of the floor mopping piece 12 can be brought to the dust collection opening 14 to be timely sucked away, on the other hand, the floor mopping piece 12 can form a seal with 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 floor cleaning element 12 includes a main body 121 and a sweeping element 122 disposed at the edge of the main body 121, in other words, the sweeping element 122 is a ring-shaped structure and surrounds the edge of the main body 121, wherein the thickness of the sweeping element 122 is greater than that of the main body 121, so that the flexibility of the middle portion of the floor cleaning element 12 is greater than that of the edge, thereby increasing the dirt carrying capacity of the main body 121 and improving the cleaning effect of the floor cleaning element 12 on the surface to be cleaned.

As can be understood by those skilled in the art, since the middle of the floor mopping member 12 is under a larger pressure and the edge of the floor mopping member 12 is under a smaller pressure, the thickness of the cleaning element 122 at the outer edge is larger than the thickness of the mopping main body 121 at the inner part, so that the contact effect of the cleaning element 122 and the surface to be cleaned can be ensured, the overall cleaning effect of the floor mopping member 12 can be improved, the effective area of the floor mopping member 12 can be increased, and the effective length of the floor mopping member 12 in the left-right direction can be ensured to be 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.

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 then the rotating floor scrubbing member 12 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 wall and furniture sides, etc., the floor wiping member 12 extending outside the body 11 can be attached to the wall or furniture side, 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 cleaning member 12 is longer than the distance between the two driving wheels 13, so that the dirt left by the driving wheels 13 is wiped away as the cleaning robot advances, and the dirt adsorbed by the mop body 121 is blocked by the cleaning member 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, by making the effective length a of the floor cleaning member 12 longer than the distance s between the driving wheels, the floor cleaning member 12 can clean the surface to be cleaned that the driving wheels 13 run over as the cleaning robot moves forward, and then wipe away the dirt that the driving wheels 13 leave on the surface to be cleaned, so that the cleaning robot does not leave dirt marks when passing through the surface to be cleaned, thereby effectively reducing the dirt residue on the household floor after cleaning, and improving the cleaning effect and 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, the thickness of the cleaning element 122 at the outer edge is greater than the thickness of the inner mopping body 121, so that the flexibility of the middle part of the mopping element 122 is greater than the flexibility of the edge, thereby increasing the dirt bearing capacity of the mopping body 121, and simultaneously ensuring the contact effect of the cleaning element 122 and the surface to be cleaned, so as to improve the overall cleaning effect of the mopping element 12, and help to ensure that the effective length of the mopping element 12 can be greater than the distance between the driving wheels 13.

As shown in fig. 1, the number of the edge brushes 15 is two, and taking one of the edge brushes 15 as an example, during the rotation of the edge brush 15, the edge brush 15 is in rotating contact with the tire of the driving wheel 13 to clean the tire surface of the wheel, so as to further improve the cleaning effect and the cleaning efficiency. Accordingly, the above-described structural relationship between the other side brush 15 and the drive wheel 13 is also adopted, so that the two side brushes 15 correspond to one drive wheel 13, respectively.

The number of the side brushes 15 may be one.
