Floor Brush Structure

Abstract

The present disclosure discloses a floor brush structure. In this solution, by installing the hard bristles and the soft bristles on the rolling body, when hairs on a floor are cleaned away, direct contact between the hairs and the hard bristles is reduced, at the same time, the hairs tangled on the rolling brush are combed by cooperating with the comb teeth, and installation parameters and structures of the bristles and the comb teeth are matched at high precision during installation, so that a floor brush achieves an efficient cleaning function.

What is claimed is: 
     
         1 . A floor brush structure, comprising:
 a housing;   a rolling brush, comprising a rolling body, hard bristles and soft bristles, wherein the rolling body is rotatably disposed in the housing, a plurality of hard bristles are disposed on an outer surface of the rolling body, a plurality of soft bristles are disposed on the outer surface of the rolling body, a height of the hard bristles is lower than a height of the soft bristles, and a height difference range of the hard bristles and the soft bristles is 0.2 mm to 5 mm; and   comb teeth, disposed in the housing and corresponding to the rolling brush, wherein when the rolling brush rotates, tooth tips of the comb teeth are able to be inserted into the hard bristles and the soft bristles to comb hairs tangled on the rolling brush, and a depth range of the tooth tips of heads of the comb teeth inserted into the hard bristles and/or the soft bristles is 0.1 mm to 5 mm.   
     
     
         2 . The floor brush structure according to  claim 1 , wherein a plurality of tooth tips of the comb teeth are arranged in an axial direction of the rolling body, a spacing range between two adjacent tooth tips is 2 mm to 6 mm, and an angle range of the tooth tips of the heads of the comb teeth is 8° to 105°. 
     
     
         3 . The floor brush structure according to  claim 1 , wherein the plurality of hard bristles are arranged on a surface of one substrate to form a plurality of hard bristle strips, the plurality of soft bristles are arranged on a surface of one substrate to form a plurality of soft bristle strips, and the hard bristle strips and the soft bristle strips are divided into a plurality of groups of one hard bristle strip and one soft bristle strip to be disposed on a surface of the rolling body. 
     
     
         4 . The floor brush structure according to  claim 3 , wherein a plurality of first grooves are formed in the surface of the rolling body, each first groove is a combined groove with two grooves as one group, one hard bristle strip is installed in one groove, and one soft bristle strip is installed in the other groove. 
     
     
         5 . The floor brush structure according to  claim 4 , wherein a spacing range between the two grooves in the combined groove is 1 mm to 15 mm. 
     
     
         6 . The floor brush structure according to  claim 1 , wherein the plurality of soft bristles and the plurality of hard bristles are disposed on a surface of one substrate at the same time to form a plurality of soft and hard bristle strips, and the soft and hard bristle strips are disposed on a surface of the rolling body. 
     
     
         7 . The floor brush structure according to  claim 6 , wherein in the soft and hard bristle strips, the plurality of hard bristles are arranged on the substrate to form a hard bristle layer, the plurality of soft bristles are arranged on the surface of the substrate to form a soft bristle layer, and the hard bristle layer and the soft bristle layer are disposed in parallel. 
     
     
         8 . The floor brush structure according to  claim 7 , wherein a spacing range between the hard bristle layer and the soft bristle layer is 0 mm to 15 mm. 
     
     
         9 . The floor brush structure according to  claim 7 , wherein a plurality of second grooves are formed in the surface of the rolling body, and one soft and hard bristle strip is installed in one second groove
