Abstract

A brush assembly, having a brush body, a brush cover mounted on the brush body, a suction port formed on the brush body, and a pet hair removal unit, is provided. The pet hair removal unit includes at least two pet hair removal members that are disposed apart from each other; and the at least two pet hair removal members rotate with respect to the brush body when the brush assembly moves forward and backward, alternately contacting a surface being cleaned, thereby removing dirt or dust such as pet hair from the surface being cleaned.

1 . A brush assembly of a vacuum cleaner, which includes a brush body, a brush cover mounted on the brush body, a suction port formed on the brush body, and a pet hair removal unit, wherein:
 the pet hair removal unit includes at least two pet hair removal members that are disposed apart from each other; and   the at least two pet hair removal members rotate with respect to the brush body when the brush assembly moves forward and backward, alternately contacting a surface being cleaned, thereby removing fibrous dirt or dust from the surface being cleaned.   
   
   
       2 . The brush assembly as claimed in  claim 1 , wherein the pet hair removal unit transfers at least part of the dirt or dust such as pet hair removed from the surface being cleaned to the suction port when the brush assembly moves forward and backward. 
   
   
       3 . The brush assembly as claimed in  claim 1 , further comprising a rotating drum that is rotatably mounted on the brush body, and of which at least one side is cut. 
   
   
       4 . The brush assembly as claimed in  claim 3 , wherein the at least two pet hair removal members are mounted on both sides of the rotating drum, and rotate along with the rotating drum. 
   
   
       5 . The brush assembly as claimed in  claim 4 , wherein the at least two pet hair removal members include directional bristles. 
   
   
       6 . The brush assembly as claimed in  claim 5 , wherein the bristles are inclined in an opposite direction against a horizon. 
   
   
       7 . The brush assembly as claimed in  claim 4 , further comprising at least two dusters that remove the dirt or dust such as pet hair off the at least two pet hair removal members, wherein the at least two dusters include bristles that are inclined in an opposite direction to each other. 
   
   
       8 . The brush assembly as claimed in  claim 7 , wherein the at least two dusters are mounted on the brush body and the brush cover. 
   
   
       9 . The brush assembly as claimed in  claim 4 , wherein the rotating drum includes a rotation leading member, and the rotation leading member contacts the surface being cleaned, and rotates the rotating drum when the brush assembly moves forward and backward. 
   
   
       10 . The brush assembly as claimed in  claim 1 , further comprising a rotating brush that is mounted on the brush assembly adjacent to the suction port. 
   
   
       11 . The brush assembly as claimed in  claim 10 , further comprising:
 a turbine fan that rotates the rotating brush,   wherein the brush cover comprises a plurality of air inlets formed thereon, and   wherein external air flows into the brush assembly through the plurality of air inlets, and drives the turbine fan.   
   
   
       12 . A brush assembly of a vacuum cleaner, comprising:
 a brush body on which a suction port is formed;   a brush cover that is mounted on the brush body;   a rotating drum that is rotatably mounted on the brush body or the brush cover, and of which at least part is cut;   a pet hair removal member that is mounted on the rotating drum; and   a duster that remove dirt or dust such as pet hair off the pet hair removal member.   
   
   
       13 . The brush assembly as claimed in  claim 12 , wherein the duster is mounted on the brush body. 
   
   
       14 . The brush assembly as claimed in  claim 12 , wherein the rotating drum comprises a side surface formed in an approximate semicircular shape. 
   
   
       15 . The brush assembly as claimed in  claim 12 , wherein the pet hair removal member and the duster include directional bristles. 
   
   
       16 . A brush assembly of a vacuum cleaner, comprising:
 a brush body;   a brush cover mounted on the brush body;   a suction port formed on the bottom surface of the brush body;   an opening is formed on the bottom surface of the brush body, the opening being approximately parallel to a front portion of the suction port;   a rotating drum rotatably mounted in the opening;   a rotation leading member mounted on a periphery of the rotating drum;   a first pet hair removal member on the periphery of the rotating drum on a first side of the rotation leading member; and   a second pet hair removal member on the periphery of the rotating drum on a second side of the rotation leading member, wherein the rotating drum rotates with respect to the brush body when the brush assembly moves forward and backward so that the first and second pet hair removal members alternately contact a surface being cleaned, thereby removing fibrous dirt or dust from the surface.   
   
   
       17 . The brush assembly as claimed in  claim 16 , wherein the first and second pet hair removal members each include directional bristles that are inclined in opposite directions to each other. 
   
   
       18 . The brush assembly as claimed in  claim 17 , further comprising a first duster that removes the fibrous dirt or dust from the first pet hair removal member and a second duster that removes the fibrous dirt or dust from the second pet hair removal member. 
   
   
       19 . The brush assembly as claimed in  claim 18 , wherein the first duster includes directional bristles that are inclined in a direction opposite to the directional bristles of the first pet hair removal member and the second duster includes directional bristles that are inclined in a direction opposite to the directional bristles of the second pet hair removal member. 
   
   
       20 . The brush assembly as claimed in  claim 18 , wherein the first and second dusters are mounted on the brush body or the brush cover.
