         6 . The automatic cleaning device according to  claim 3 , wherein a support structure is disposed below the second portion of the top cover, and is configured to support the second portion of the top cover, and the support structure and at least part of the accommodating portion are integrally molded. 
     
     
         7 . The automatic cleaning device according to  claim 6 , wherein a surface of the second chamber comprises a groove, the groove is substantially matched with a contour of the support structure, and the groove is configured to accommodate the support structure when the second portion of the top cover is accommodated in the second chamber. 
     
     
         8 . The automatic cleaning device according to  claim 2 , wherein the top cover is symmetrically disposed along a central axis in the advancing direction of the automatic cleaning device. 
     
     
         9 . The automatic cleaning device according to  claim 8 , wherein the top cover has a shape of at least one or a combination of: a D-shape, a rectangle, a square, a circle, an oval, a triangle, a quadrilateral, a pentagon, a hexagon, a heptagon or an octagon. 
     
     
         10 . The automatic cleaning device according to  claim 2 , wherein the dust box comprises:
 a first opening located in a first side wall of the dust box;   a second opening located in a second side wall of the dust box opposite to the first side wall; and   a filter detachably assembled to the second opening.   
     
     
         11 . The automatic cleaning device according to  claim 10 , wherein the cleaning module further comprises a fan disposed below the second chamber and corresponding to the second opening, and the fan is configured to provide a suction force to suck debris into the dust box from the first opening. 
     
     
         12 .
