         5 . The floor brush assembly as claimed in  claim 3 , wherein the second scraping piece is made from deformable materials, wherein the external force is the friction between the second scraping piece body and the surface to be cleaned; or the second scraping piece is made from hard materials, wherein the external force is from the driver on the floor brush base, which is configured to facilitate switching of the second scraping piece between the third state and the fourth state. 
     
     
         6 . The floor brush assembly as in  claim 3 , wherein when the second scraping piece is made from deformable materials, the floor brush base is provided with an extension baffle on front of the second scraping piece, wherein the bottom edge of the extension baffle is lower than the second mounting part;
 when the floor brush assembly moves backward, the second bumps abut on the bottom edge of the extension baffle;   wherein the extension baffle is configured to exert pressure down to the second scraping piece in the third state so as to make the second scraping piece abut on the surface to be cleaned tightly.   
     
     
         7 . The floor brush assembly as claimed in  claim 5 , wherein when the second scraping piece is made from hard materials, the second scraping piece is hinged to the bottom of the floor brush base through the second mounting part. 
     
     
         8 . The floor brush assembly as claimed in  claim 7 , the floor brush base is provided with stop blocks to limit the swing angle of the second scraping piece;
 wherein the stop blocks are one pair, with one of the stop blocks being arranged on the floor brush base and on the side of the second mounting part away from the roller brush to limit the swing angle when the second scraping piece swings forward and the other stop block being arranged on the floor brush base and on the side of the second mounting part close to the roller brush to limit the swing angle when the second scraping piece swings backward; or,   wherein the number of the stop block is one which is provided with the second limitation face close to the roller brush and the first limitation face away from the roller brush;   when the second scraping piece swings forward, the second scraping piece abutting on the first limitation face; when the second scraping piece swings backward, the second scraping piece abutting on the second limitation face.   
     
     
         9 . The floor brush assembly as claimed in  claim 1 , wherein the first scraping assembly is arranged on the bottom of the floor brush base and behind the roller brush, with a suction inlet being formed between the first scraping piece and the roller brush;
 wherein the first scraping piece abuts on the surface to be cleaned to scrape off dirt when the floor brush assembly moves forward and/or backward.   
     
     
         10 . The floor brush assembly as claimed in  claim 5 , wherein the first scraping assembly is arranged on the bottom of the floor brush base and behind the roller brush, with a suction inlet being formed between the first scraping piece and the roller brush;
 with at least two first bumps being arranged on the face away from the roller brush and distributed at intervals on the length direction of the first scraping piece;   wherein the second scraping piece abuts on the surface to be cleaned and the first bump abuts on the surface to be cleaned when the floor brush assembly moves backward, with a first channel for dirt passing through being formed between the adjacent first bumps to make dirt reach the suction inlet.   
     
     
         11 . The floor brush assembly as claimed in  claim 9 , wherein the first and auxiliary rollers are arranged on the bottom of the floor brush base and the second scraping piece and first scraping piece remain suspended in natural state;
 wherein the bottom edges of the second scraping piece and the first scraping piece are lower than the lowest side of the first and auxiliary rollers when the second scraping piece and the first scraping piece are in natural state.   
     
     
         12 . The floor brush assembly as claimed in  claim 9 , wherein the floor brush base comprises the main base and the detachable roller brush cover on the main base, which form a roller brush cavity to hold the roller brush;
 the sealing element is arranged between the roller brush cover and the main base, on the top of the roller brush cover and/or the main base and on the top of the roller brush cavity for reducing or eliminating the gap between the main base and the roller brush cover so as to enhance the sealing performance of the top of the roller brush cavity.   
     
     
         13 . The floor brush assembly as claimed in  claim 12 , wherein the first scraping piece and the second scraping piece abut on the surface to be cleaned when the floor brush assembly moves backward component, with a seal structure being formed jointly by the first scraping piece, the second scraping piece and the sealing to improve the vacuum degree of the roller brush cavity. 
     
     
         14 . The floor brush assembly as claimed in  claim 12 , wherein the sealing component is arranged on the inner side of the roller brush cover and close to the end of the roller brush;
 wherein the sealing component extends along the circumferential direction of the roller brush.   
     
     
         15 . The floor brush assembly as claimed in  claim 12 , wherein the second scraping piece is arranged on the inner side of the roller brush cover and comprises a second mounting part which is arranged on the side of the second scraping piece body away from the surface to be cleaned; with an insertion part being arranged on the inner side of the roller brush cover to match with the second mounting part and the second scraping piece being installed on the inner side of the roller brush cover by the second mounting part matching with the abutting part.
