The embodiment of the application discloses a cleaning robot.

Referring to fig. 1, illustrating a bottom structure of a cleaning robot, an embodiment of the cleaning robot provided in an embodiment of the present application includes:

the cleaning robot consists of a body 1 and a power assembly 2; the power assembly 2 is arranged on the body 1 and comprises 2 driving wheels 21 which are respectively arranged on two opposite sides of the body 1 and used for driving the body 1 to move; a cleaning assembly 11 and a recovery assembly 12 are further arranged on the body 1 of the cleaning robot, wherein the cleaning assembly 11 is used for cleaning and scrubbing the cleaning surface, and the recovery assembly 12 is used for recovering sewage and dirt after cleaning and scrubbing the cleaning surface.

Referring to fig. 2, which shows an exploded structure of the cleaning robot body, in the present embodiment, the cleaning assembly 11 includes a roller 111, a liquid supply part 112, and a floor wiper 113. The drum 111 is rotated by the driving of a drum motor (not shown), and the rotation direction of the drum 111 at the time of operation coincides with the rotation direction of the driving wheel 21, which wipes the cleaning surface during rotation; the liquid supply part 112 supplies cleaning liquid such as water, decontamination liquid, disinfectant for cleaning operation, the cleaning assembly 11 further comprises a water pump 114 and liquid outlet holes 115, the liquid outlet holes 115 are uniformly arranged around the drum 111, the water pump 114 is connected with the liquid outlet holes 115 through a liquid conveying pipeline (not shown), after the water pump 114 pumps out the cleaning liquid in the liquid supply part 112, the cleaning liquid is uniformly sprayed onto the rotating drum 111 through the liquid outlet holes 115 to provide the cleaning liquid for the cleaning operation, and the drum 111 sends the cleaning liquid to a cleaning surface through rotation and cleans the cleaning surface in the repeated rotation process; the ground scraper 113 is arranged below and behind the roller 111, the mounting end of the ground scraper 113 is connected to the body 1, the ground contact end of the ground scraper 113, which is in contact with the cleaning surface, is flush with the lowest part of the roller 111 in the height direction, after the roller 111 wipes the ground, sewage and dirt are generated, part of the sewage and the dirt are brought into the body 1 by the roller, and the other part of the sewage and the dirt are left on the ground, the ground scraper 113 can concentrate the part of the sewage and the dirt left on the ground behind the roller 111, and the roller 111 gradually brings the rest part of the sewage and the dirt into the body in the later rotating process. Preferably, the ground contact end of the ground scraper 113 is inclined towards the retreating direction of the cleaning robot (the two directions are not completely the same, namely the included angle is an acute angle), so that the performance of concentrating sewage and dirt is ensured, and the risk that the ground scraper 113 is blocked by an obstacle is avoided.

In this embodiment, the recovery unit 12 includes a suction port 121, a suction fan 122 and a dirt collection box 123, wherein one end of the suction port 121 is disposed near the roller 111 for the suction port 121 to absorb the dirt and the sewage generated by the rotation of the roller 111 from the cleaning surface, the dirt collection box 123 is connected to the other end of the suction port 121 for receiving the dirt and the sewage coming out from the other end of the suction port 121, the dirt collection box 123 is connected to the other end of the suction port 121 through a dirt collection pipe (not shown), the suction fan 122 is disposed at an air outlet (not shown) of the dirt collection box 123, so that the suction port 121 and the dirt collection box 123 form a path capable of absorbing the dirt and the sewage, and the suction fan 122 provides a suction force to the path. In addition, the outlet of the dirt collection box 123 is provided with a filter structure (not shown) to separate gas, liquid and solids, thereby preventing sewage and dirt from being drawn into the suction fan.

Preferably, referring to fig. 2, showing the internal decomposition structure of the cleaning robot body 1, the suction opening 121 is a circular opening, one end is connected with the dirt collecting pipe, the other end faces the roller 111, a surrounding plate 124 is arranged around one end of the suction opening 121 facing the roller 111, the opening of the surrounding plate 124 faces the roller 111, and the opening range of the surrounding plate 124 is slightly larger than that of the roller 111, so that the roller 111 at least partially extends into the surrounding plate 124 and is close to the surrounding plate 124, thereby facilitating the suction opening 121 to absorb the dirt and the dirt on the roller 111. During the concrete implementation, suction inlet 121 can set up 2 or more, and the setting of the both ends bore shape of every suction inlet 121 is unanimous, so, can be with bounding wall 124 and suction inlet 121 integrated into one piece, the demolding is simpler, has saved the cost simultaneously.

In this embodiment, the power assembly 2 further includes a rotating electrical machine, such as a servo motor capable of rotating forward and backward, and in order to make the rotation control more stable, the power assembly may specifically include a reduction box, that is, the power assembly is composed of the rotating electrical machine and the reduction box, and the details are not limited.

In a preferred embodiment, in the recovery unit 12, a check valve 125 is disposed between the suction port 121 and the dirt collection tank 123 and is installed at one end of the dirt collection pipe connected to the dirt collection tank 123, so as to effectively prevent the dirt received in the dirt collection tank 123 from flowing backward.

In a preferred embodiment, the recycling assembly 12 further comprises a roller scraper bar 126, the roller scraper bar 126 being arranged in an upper orientation of the roller 111, one end of the roller scraper bar 126 being mounted on the body and the other end of the roller scraper bar extending in a length direction of the roller 111 along a line formed by a contact point with the roller 111, in particular, the upper orientation of the roller 111 includes a region towards which an upper half of the roller 111 is directed when inverted. Further, the contact end of the roller scraping strip 126 and the roller 111 is inclined towards the opposite direction of the rotation direction of the contact point (the two directions are not completely opposite, that is, the included angle is an obtuse angle), so that the working strength of the roller scraping strip 126 is enhanced, and further, the sewage and dirt stuck on the roller 111 can be more easily sucked into the dirt collection tank 123 by the suction port 121.

In a preferred embodiment, as shown in fig. 3, the bottom structure of the cleaning robot, D represents the distance between the two driving wheels 21 on the opposite sides of the body 1, L represents the length of the roller 111, the roller 111 is disposed behind the driving wheels 21 on the opposite sides of the body, and the length of the roller 111 is not less than the distance between the driving wheels 21 on the opposite sides of the body 1 and is disposed with the centers aligned. When the cleaning robot actually performs cleaning operation, the driving wheels 21 of the cleaning robot may leave dark or shallow traces after walking, and at this time, because the roller 111 is disposed behind the driving wheels 21 and has a length not less than the distance between the driving wheels 21 on both sides, the cleaning path of the roller 3 completely covers the traces after walking of the driving wheels 21, thereby improving the cleaning effect.

While the cleaning robot provided by the present application has been described in detail, it will be apparent to those skilled in the art that the embodiments and applications of the cleaning robot can be modified according to the spirit of the present application.
