         2 . The cleaning scraping strip according to  claim 1 , wherein
 a distance from an edge of the notch of the working portion to a bottom of the notch in a horizontal direction is defined as a notch depth B, a distance from an edge of the notch of the working portion to a surface of the connecting portion in a vertical direction is defined as a notch width D, and 0.45≤B/D≤0.7.   
     
     
         3 . The cleaning scraping strip according to  claim 1 , wherein
 a thickness of the connection along a horizontal direction is defined as C, and 0.5 mm≤C≤1.5 mm.   
     
     
         4 . The cleaning scraping strip according to  claim 1 , wherein
 a height of the working portion from a first end to a second end in a vertical direction is defined as A, and the height A is greater than or equal to a ground clearance of the cleaning robot by 0.5 mm and the height A is less than or equal to a ground clearance of the cleaning robot by 1.5 mm.   
     
     
         5 . The cleaning scraping strip according to  claim 1 , wherein
 an acute angle is formed between a length extension direction of the working portion and the ground.   
     
     
         6 . The cleaning scraping strip according to  claim 1 , wherein
 the connecting portion comprises a connecting head section and a transition section;   a first end of the connecting head section is installed at a bottom of the cleaning robot, a second end of the connecting head section is connected to a first end of the transition section, a second end of the transition section is connected to a first end of the working portion, and the transition section extends obliquely downward in the advancing direction of the cleaning robot.   
     
     
         7 . The cleaning scraping strip according to  claim 6 , wherein
 the connecting head section, the transition section and the working portion are integrally formed with a flexible material.   
     
     
         8 . The cleaning scraping strip according to  claim 6 , wherein
 at least one force-bearing step for bearing a force exerted by the cleaning robot is formed on the transition section and/or the connecting head section, and the force-bearing step is arranged at a side of the transition section and/or the connecting head section away from the advancing direction of the cleaning robot.   
     
     
         9 . A cleaning robot, comprising a housing and the cleaning scraping strip according to  claim 1 , wherein the cleaning scraping strip is installed at a bottom of the housing. 
     
     
         10 . The cleaning robot according to  claim 9 , further comprising a cleaning element, wherein the cleaning element is arranged on the housing and configured to clean the ground; and in the advancing direction of the cleaning robot, the cleaning scraping strip is located behind the cleaning element. 
     
     
         11 . The cleaning robot according to  claim 10 , wherein
 an inner cavity is defined in the housing;   the cleaning element is a rolling brush, and the rolling brush is arranged in the inner cavity and extends out of the inner cavity to scrub the ground;   a side of the cleaning scraping strip facing the rolling brush is configured as an arc-shaped surface that matches an outer contour of the rolling brush; and   the cleaning scraping strip and the rolling brush are spaced apart from each other.   
     
     
         12 . The cleaning robot according to  claim 11 , further comprising a force-bearing member,
 wherein the force-bearing member is installed at a cavity wall of the inner cavity, and a side of the cleaning scraping strip facing away from the cleaning member abuts against the force-bearing member.
