The following describes a specific structure of the cleaning robot provided with the floating roller brush according to the present application with reference to the accompanying drawings.

It should be understood by those skilled in the art that the embodiments described below are only preferred embodiments of the present application, and do not mean that the present application can be implemented only by the preferred embodiments, which are merely for explaining the technical principles of the present application and are not intended to limit the scope of the present application. All other embodiments that can be derived by a person skilled in the art from the preferred embodiments provided herein without inventive step should still fall within the scope of protection of the present application.

Preferred embodiments of the present application:

as shown in fig. 1, the cleaning robot 1 of the present embodiment includes a body 11, a mop 12, a driving wheel 13, a roller brush assembly 14, and a dust suction fan (not shown). An opening 111 for accommodating the roller brush assembly 14 is formed in the bottom of the machine body 11, meanwhile, the opening 111 is communicated with a dust collection fan, and the mopping piece 12, the driving wheel assembly 13, the roller brush assembly 14 and the dust collection fan are arranged on the machine body 11, wherein the mopping piece 12 is used for mopping and cleaning a surface to be cleaned, the driving wheel 13 is used for driving the cleaning robot 1 to move forward, and the roller brush assembly 14 is used for sweeping garbage on the surface to be cleaned into the opening 111 so that the dust collection fan can suck the garbage.

As shown in fig. 2 and 3, roller brush assembly 14 includes a roller brush 141 and a floating bracket 142, floating bracket 142 has a dirt pickup opening 1421, dirt pickup opening 1421 communicates with opening 111, and roller brush 141 is pivotally connected to floating bracket 142 and passes partially through dirt pickup opening 1421 so as to be able to contact and roll on a surface to be cleaned to sweep up the dirt on the surface to be cleaned. The floating bracket 142 is provided with a rotation shaft 143, and the entire roller brush assembly 14 is pivotally connected to the cleaning robot 1 through the rotation shaft 143 such that the entire roller brush assembly 14 can move up and down with respect to the cleaning robot 1. And, the front portion of the roller brush assembly 14 is pivotally connected to the body 11, i.e., the rotational shaft 143 of the roller brush assembly 14 mounted to the cleaning robot 1 is forward with respect to the entirety of the roller brush assembly 14 in the front-rear direction of the cleaning robot 1. In addition, during the process of the up-and-down floating of the roller brush assembly 14 relative to the body 11, the lowest end of the roller brush assembly 14 floating to the highest position is not higher than the opening 111, that is, the bottom of the roller brush assembly 14 at the highest position is exposed out of the opening 111 or is as high as the opening 111, and the lowest end of the roller brush assembly 14 floating to the lowest position is lower than the bottom surface of the wiping part 12, so as to ensure that the roller brush 141 can contact with the surface to be cleaned.

As shown in fig. 4, the dotted line represents the portion of the roller brush assembly 14 higher than the opening 111, the solid line represents the portion of the roller brush assembly 14 lower than the opening 111, during the process of the roller brush assembly 14 floating up and down, at least a portion of the rear end of the roller brush assembly 14 is not higher than the rear edge of the opening 111 (i.e. the portion of the roller brush assembly 14 located on the left side of the dotted line is exposed from the opening 111) to avoid the rear edge of the opening 111 from being scratched, in addition, the height of the front end of the bottom surface of the roller brush assembly 14 is not lower than the front edge of the opening 111 (i.e. the portion of the roller brush assembly 14 located on the right side of the dotted line is located above the opening 111), since the pivot shaft connecting the roller brush assembly 14 to the machine body 11 is located at the front end, the portion of the roller brush assembly 14 closer to the front end is less likely to rotate under force, and therefore, by making the height of the front end of the bottom surface of the roller brush assembly 14 not lower than the opening 111, it is possible to prevent an obstacle from contacting the front side of the roller brush assembly 14 to block the cleaning robot 1 from advancing. Moreover, the portion of the front end of the roller brush assembly 14 exposed from the opening 111 is an inclined surface, which can guide the contact between the front end of the roller brush assembly 14 and an obstacle, so that the roller brush assembly 14 can be more easily jacked up by the obstacle to pass over the obstacle.

Although not shown in the drawings, it is preferable that an elastic member is provided between the roller brush assembly 14 and the body 11, and the elastic member can provide a floating force to the roller brush assembly 14, thereby ensuring that the roller brush 141 can be brought into contact with a surface to be cleaned.

As shown in fig. 5, preferably, the front end of the floating bracket 142 is provided with a front soft member 144, and the width of the front soft member 144 (the dimension of the front soft member 144 extending from the bottom of the body 11 to a direction away from the body 11) is greater than the distance from the front soft member 144 to the front edge of the opening 111, so that the front soft member 144 pressed forward can cover the gap between the floating bracket 142 and the front edge of the opening 111 during the process of retracting the cleaning robot 1, thereby preventing dirt from entering and accumulating in the installation gap between the front end of the floating bracket 142 and the front edge of the opening 111 to affect the movement of the floating bracket 142. In addition, the rear end of the floating bracket 142 is transversely provided with the rear soft piece 145, the width of the rear soft piece 145 (the size of the rear soft piece 145 extending from the floating bracket 142 to the direction far away from the floating bracket 142) is larger than the distance from the rear soft piece 145 to the rear edge of the opening 111, and the rear soft piece 145 pressed down backwards can cover the gap between the floating bracket 142 and the rear edge of the opening 111 in the process of advancing the cleaning robot 1, so that the dirt can be prevented from entering and accumulating in the installation gap between the floating bracket 142 and the rear edge of the opening 111, and meanwhile, the rear soft piece 145 can prevent the edge brush or the roller brush 141 of the cleaning robot 1 from poking the dirt on the surface to be cleaned to the rear of the dirt pick-up opening 1421. Also, the front soft member 144 and the rear soft member 145 collectively function to reduce the size of the port through which the cleaning robot 1 sucks air, thereby increasing the suction force to the surface to be cleaned.

It should be noted that, according to different product requirements, only one of the front flexible member 144 and the rear flexible member 145 may be provided; alternatively, the front soft member 144 may be disposed at the front edge of the opening 111 and have a width greater than the distance to the front end of the floating bracket 142 to cover the installation gap of the floating bracket 142 and the front edge of the opening 111 when the cleaning robot 1 advances; alternatively, the rear soft member 145 may be disposed at the rear side of the rear edge of the opening 111 and have a width greater than the distance to the rear end of the floating holder 142 to cover the installation gap of the floating holder 142 and the rear edge of the opening 111 when the cleaning robot 1 retreats.

Referring to fig. 1 to 5, when the cleaning robot 1 of the present embodiment performs a cleaning operation, the rotating driving wheel 131 drives the cleaning robot 1 to move forward on a surface to be cleaned, the wiping part 12, the roller brush 141 and the surface to be cleaned contact each other, the wiping part 12 can wipe the surface to be cleaned, and the rotating roller brush 141 can sweep up garbage on the surface to be cleaned, so that the cleaning robot 1 can suck the garbage. At the same time, the front soft member 144 and the rear soft member 145 are pressed down to cover the installation gap between the floating bracket 142 and the opening 111, preventing dirt from entering the gap. When the cleaning robot 1 encounters an obstacle, in the process of crossing the obstacle, the inclined guide surface at the front end of the roller brush assembly 14 contacts with the obstacle first, so that the roller brush assembly 14 is gradually jacked up by the obstacle, but even if the roller brush assembly 14 is jacked to the highest position, the bottom of the roller brush assembly 14 is not higher than the opening 111, so that the obstacle cannot extend into the opening 111, and the obstacle is prevented from contacting with the rear side wall of the opening 111.

As can be understood by those skilled in the art, by making the lowest end of the roller brush assembly 14 floating to the highest position not higher than the opening 111, the obstacle is blocked by the roller brush assembly 14 and cannot extend into the opening 111, so that the rear side wall of the obstacle opening 111 is prevented from contacting, and the situation that the cleaning robot 1 cannot move due to the obstacle jamming the rear side wall of the opening 111 is avoided, so that the cleaning robot 1 can better surmount the obstacle.

Further, by providing the front soft member 144 at the front end of the floating holder 142 and making the width of the front soft member 144 larger than the distance thereof to the front edge of the opening 111, the front soft member 144, which is pressed down, can cover the mounting gap between the floating holder 142 and the front edge of the opening 111 during the backward movement of the cleaning robot 1, thereby preventing dirt on the surface to be cleaned from entering and accumulating in the mounting gap between the floating holder 142 and the front edge of the opening 111. In addition, by providing the rear soft member 145 at the rear end of the floating holder 142 and making the width of the rear soft member 145 larger than the distance thereof to the rear edge of the opening 111, the fallen rear soft member 145 can cover the mounting gap between the floating holder 142 and the rear edge of the opening 111 during the forward movement of the cleaning robot 1, thereby preventing dirt on the surface to be cleaned from entering and accumulating in the mounting gap between the floating holder 142 and the rear edge of the opening 111. Also, the rear soft member 145 contacts the surface to be cleaned, and can prevent the edge brush or the roller brush 141 of the cleaning robot 1 from poking dirt on the surface to be cleaned to the rear of the dirt pickup opening 1421, and prevent air behind the dirt pickup opening 1421 from entering the dirt pickup opening 1421, so that air enters the dirt pickup opening 1421 from the front side, the left side, and the right side of the dirt pickup opening 1421, thereby allowing the cleaning robot 1 to provide a sufficient suction force to the surface to be cleaned.

As shown in fig. 6, the cleaning robot 1 of the present embodiment is further provided with a base station 2, and the base station 2 includes a base station body 21 and a base 22. The base station body 21 is provided with a cleaning cavity 211, and the bottom of the cleaning cavity 211 is provided with cleaning members such as cleaning ribs for cleaning the mop 12 of the cleaning robot 1. The base 22 is used to guide the cleaning robot 1 to dock with the base station 2.

Further, the base station body 21 is provided with the charging terminal 23, the base 22 is provided with an inclined guide surface 221, the cleaning robot 1 is provided with a power receiving terminal (not shown) butted with the charging terminal 23, the guide surface 221 is provided with a positioning groove 222, the driving wheel 131 moves to the edge of the positioning groove 222, the power receiving terminal is contacted with the charging terminal 23, the driving wheel 131 is placed in the positioning groove 222, and the power receiving terminal is butted against the charging terminal 23 so that the charging terminal moves backward and downward relative to the base station body 21. Meanwhile, the cleaning robot 1 sinking in the positioning groove 222 causes the rear soft member 145 to be pressed against the top surface of the base 22.

As shown in fig. 6, the base station body 21 is further provided with a water blocking member 24, the water blocking member 24 is a flexible strip-shaped structure, and the shape of the water blocking member 24 matches the shape of the cleaning robot 1, so that the water blocking member 24 can abut against the cleaning robot 1 and deform under the extrusion of the cleaning robot 1. Preferably, the water blocking member 24 protrudes from the base station body 21 by a length greater than that of the charging terminal 23 from the base station body 21 so that the water blocking member 24 comes into abutment with the cleaning robot 1 prior to the charging terminal 23.

The use of the base station 2 is explained in connection with fig. 1 and 6:

when the cleaning robot 1 needs to be charged or the mop 12 needs to be cleaned, the cleaning robot 1 moves to the base station 2 by itself, and enters the base station 2 in a backward manner (i.e. the rear side of the cleaning robot 1 where the mop 12 is located enters the base station 2 first), first, the cleaning robot 1 on the surface to be cleaned travels on the guide surface 221, and advances along the guide surface 221, the cleaning robot 1 on the guide surface 221 is in an inclined state, and as the cleaning robot 1 travels on the guide surface 221, the cleaning robot 1 abuts against the water blocking member 24 first, when the cleaning robot 1 travels to the edge of the positioning groove 222 (i.e. will enter the positioning groove 222 or has entered a small part of the positioning groove 222), the power receiving terminal of the cleaning robot 1 contacts with the charging terminal 23, and as the driving wheel 13 of the cleaning robot 1 moves in the positioning groove 222, the movement state of the cleaning robot 1 is that the cleaning robot advances and moves down, while gradually returning to the horizontal state, during which the charging terminal 23 abutting against the cleaning robot 1 is moved backward and downward with respect to the base station body 21 by the drive of the cleaning robot 1, so that the charging terminal 23 and the power receiving terminal of the cleaning robot 1 are held in close abutment. After the cleaning robot 1 is stabilized at the lowest point of the positioning groove 222, the wiping part 12 of the cleaning robot 1 contacts with the cleaning rib at the bottom of the cleaning cavity 211, the cleaning robot 1 is tightly abutted to the water blocking member 24, and the rear soft part 145 at the bottom of the cleaning robot 1 is tightly abutted to the top surface of the base 22. Then, the mop 12 of the cleaning robot 1 is cleaned in the cleaning cavity 211, the liquid below the cleaning robot 1 is blocked by the body 11 and the water blocking member 24 and does not splash to other parts of the cleaning robot 1 and the charging terminal 23, and the rear soft member 145 is in close contact with the top surface of the base 22, and since the rear soft member 145 is located between the mop 12 and the roller brush 141, the dirty liquid thrown off by the mop 12 can be blocked, the dirty liquid is prevented from flowing to the roller brush 141 of the cleaning robot 1, and meanwhile, the base station 2 charges the cleaning robot 1.

As can be understood by those skilled in the art, by movably disposing the charging terminal 23 on the base station body 21, the charging terminal 23 can be abutted with the cleaning robot 1 when the driving wheel 13 of the cleaning robot 1 travels to the edge of the positioning groove 222 (i.e. when the driving wheel will enter the positioning groove 222 or has entered a small part of the positioning groove 222), and then the charging terminal 23 moves backward and downward relative to the base station body 21 as the cleaning robot 1 moves in the positioning groove 222, so that the two are relatively stationary, thereby resolving the kinetic energy of the cleaning robot 1, helping to reduce the impact force of the cleaning robot 1 on the charging terminal 23 and the friction force between the cleaning robot and the charging terminal 23 during the descending process, and protecting the charging terminal 23. In the charging process, even if the cleaning robot 1 shakes under the external disturbance, the charging terminal 23 can also move along with the movement of the cleaning robot 1, so that the cleaning robot 1 is always kept in close butt joint with the charging terminal, the charging terminal is not easy to break away from contact, the friction of the charging terminal 23 caused by the shaking of the cleaning robot 1 can be reduced, and the charging terminal 23 is further protected.

Further, by providing the water blocking member 24 in contact with the cleaning robot 1, the cleaning liquid can be isolated at the bottom of the cleaning robot 1, and the cleaning liquid at the bottom of the cleaning chamber 211 can be prevented from being splashed onto other parts of the cleaning robot 1 and the charging terminal 23 when the wiper 12 of the cleaning robot 1 is cleaned. Moreover, after the cleaning robot 1 and the base station 2 are connected, the rear flexible member 145 can be pressed against the top surface of the base 22, and since the rear flexible member 145 is located between the wiping member 12 and the roller brush 141, the dirt thrown out by the wiping member 12 can be blocked, and the dirt can be prevented from flowing to the roller brush 141 of the cleaning robot 1.

So far, the technical solutions of the present application have been described in connection with the foregoing preferred 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 the above preferred embodiments. The technical solutions in the above preferred 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, etc. made within the technical concept and/or technical principles of the present application will fall within the protection scope of the present application.
