Intelligent cleaning robot

Abstract

An intelligent cleaning robot includes a housing, and a floor brush assembly and a dust suction apparatus mounted therein. The floor brush assembly has a first and second accommodating cavities, a partition plate separating the cavities, and a first and second rotatable brushes exposed from the bottom of the housing and accommodated in the cavities. A gap exists between a bottom of the partition plate and the floor. A slit is formed between the first rotatable brush and the partition plate. The dust suction apparatus includes a dust suction conduit and a dust collecting box. Two ends of the conduit are in communication with the first accommodating cavity and the box respectively. The two brushes rotate in opposite directions, the rotation of the first rotatable brush makes dirt enter the conduit through the slit, and the rotation of the second rotatable brush makes dirt enter the slit through the gap.

What is claimed is: 
     
         1 . An intelligent cleaning robot for automatically cleaning dirt on the floor, comprising:
 a housing;   a floor brush assembly, mounted in the housing, and comprising:
 a first accommodating cavity; 
 a second accommodating cavity; 
 a partition plate separating the first accommodating cavity and the second accommodating cavity, wherein a gap exists between a bottom edge of the partition plate and the floor; and 
 a first rotatable brush and a second rotatable brush respectively accommodated in the first accommodating cavity and the second accommodating cavity, wherein the first rotatable brush and the second rotatable brush are exposed from the bottom of the housing, and a slit for dirt to pass through is formed between the first rotatable brush and the partition plate; and 
   a dust suction apparatus, mounted in the housing, and comprising a dust suction conduit and a dust collecting box, wherein one end of the dust suction conduit is only in communication with the first accommodating cavity, and the other end of the dust suction conduit is in communication with the dust collecting box,   wherein when the intelligent cleaning robot cleans the floor, the first rotatable brush and the second rotatable brush rotate in opposite directions, the rotation of the first rotatable brush makes dirt enter the dust suction conduit through the slit, and the rotation of the second rotatable brush makes dirt enter the slit through the gap.   
     
     
         2 . The intelligent cleaning robot according to  claim 1 , wherein the second rotatable brush has an elastic tube, multiple blades protrude outward in a radial direction on an outer surface of the elastic tube, and a height of the blades is less than a height of the gap. 
     
     
         3 . The intelligent cleaning robot according to  claim 1 , wherein the partition plate is provided with a compliance portion at a bottom end thereof, the compliance portion leans towards the second rotatable brush, and the gap is formed between the compliance portion and the floor. 
     
     
         4 . The intelligent cleaning robot according to  claim 1 , wherein the first rotatable brush has a first rotating shaft, the second rotatable brush has a second rotating shaft, and the first and second rotating shafts are in a same horizontal plane. 
     
     
         5 . The intelligent cleaning robot according to  claim 1  or  4 , wherein a diameter of the first rotatable brush is equal to a diameter of the second rotatable brush. 
     
     
         6 . The intelligent cleaning robot according to  claim 1 , wherein the first rotatable brush and the second rotatable brush each have a rigid driving shaft, a section of each of the rigid driving shafts is not in a shape of a perfect circular. 
     
     
         7 . The intelligent cleaning robot according to  claim 6 , wherein an elastic tube is sleeved over the rigid driving shaft, and an elastic material is filled between the elastic tube and the rigid driving shaft. 
     
     
         8 . The intelligent cleaning robot according to  claim 1 , further comprising two side brushes, wherein
 each of the side brushes comprises a rotating seat, and at least one bristle body extending downward in a protruding manner from the rotating seat; and   a mounting surface is formed in a recessed manner upward on each of two sides of the bottom of the housing, a mounting slot is further provided in a recessed manner on the mounting surface, the rotating seat is mounted in the mounting slot in a fitting manner, and a bottom surface of the rotating seat is in a same plane as the mounting surface.   
     
     
         9 . The intelligent cleaning robot according to  claim 1 , wherein the dust suction apparatus has a frame mounted in the housing, the frame is provided with a placement slot that is recessed from a top surface thereof downward, the placement slot is upwardly exposed from the housing, the dust collecting box is placed into the placement slot downward from above, the frame is provided with a fixed opening in communication with the placement slot, the fixed opening is correspondingly in communication with the dust suction conduit in a fixed manner, and the dust collecting box is provided with an opening that is correspondingly in communication with the fixed opening. 
     
     
         10 . The intelligent cleaning robot according to  claim 9 , wherein the dust suction apparatus further comprises a flexible baffle, the flexible baffle is pivotally connected to the dust collecting box, at least one stopping block is disposed at the fixed opening of the frame, and when the dust collecting box is placed in the placement slot, the stopping block urges against the flexible baffle and drives the flexible baffle to rotate, making the opening in an open state.
