Cleaning device and robot

Abstract

The present invention discloses a cleaning device and a robot. A movable box is disposed on the bottom side of the robot, wherein a roller space in the movable box is disposed with a roller, and a cleaning cover is disposed around an opening of the movable box. When the robot is moving and sweeping the ground with the roller, the roller will rotate to make contact with a guide element so that the guide element removes the garbage and dust attached to the roller and at the same time guides the airflow of a suction port of the robot, thereby allowing the garbage and dust to follow the airflow into the robot.

1 . A cleaning device disposed on a bottom side of a robot, comprising:
 a movable box installed around a suction port disposed on the bottom side of the robot, wherein a movable space is disposed in the movable box;   a roller, wherein the roller is pivotally disposed in the roller space, and the surface of the roller is disposed with a plurality of cleaning portions, a part of each cleaning portion is in the roller space, and another part of each cleaning potion protrudes out of the roller space, and the roller rotates to sweep the foreign substances near the suction port to the suction port with each cleaning portion;   a cleaning cover disposed around the opening of the movable box facing toward the roller space, wherein a cleaning opening is disposed in the middle of the cleaning cover to communicate with the roller space, and a guide element is disposed between the roller and the suction port; and   when each cleaning portion of the roller is in contact with the guide element through the cleaning opening, the guide element removes the foreign substances attached to each cleaning portion and guides the airflow to the suction port to have the foreign substances sucked into the robot through the suction port.   
     
     
         2 . The cleaning device as claimed in  claim 1 , wherein one end of the guide element is disposed at one end of the cleaning cover, and the other end of the guide element is disposed at the other end of the cleaning cover, and between the two ends of the guide element, the cleaning device comprises:
 a first side disposed on a side of the guide element facing toward the roller space;   a second side disposed opposing to the first side;   a guide face disposed between the first side and the second side;   wherein the guide face is curved and a concave surface of the guide face concaves to the roller; and   wherein the second side is formed in an arc shape, and a concave surface of the second side concaves to the suction port, a curvature of the two ends of the second side is smaller than that of the middle of the second side.   
     
     
         3 . The cleaning device as claimed in  claim 2 , wherein the guide element divides the cleaning opening into a roller area and a suction port area, and the suction port area is closer to the suction port than the roller area; and
 the area of the suction port area is smaller than that of the roller area, so that the airflow of the suction port area is guided to the suction port.   
     
     
         4 . The cleaning device as claimed in  claim 2 , wherein the cleaning cover is further disposed with a plurality of brackets, and one end of each bracket is disposed on the side of the cleaning cover near the suction port and extends toward the roller, so that the other side of each bracket is disposed on the side of the cleaning cover near the roller; and
 each bracket is connected to the second side and the middle of the guide face, so that each bracket crosses each other at the guide element and supports the guide element.   
     
     
         5 . The cleaning device as claimed in  claim 1 , wherein each cleaning portion is a pastry brush, scrubbing brush, rubber brush, sponge brush, or a combination of any two mentioned above. 
     
     
         6 . The cleaning device as claimed in  claim 1 , wherein the guide element is made of a rigid material and deforms each cleaning portion when making contact with each cleaning portion, so as to remove the foreign matter attached to each cleaning portion. 
     
     
         7 . A robot including the cleaning device as claimed in  claim 1 .
