Description

technical field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a floor brush used for a surface cleaning device. Background technique

[0002] Now the conventional floor brush mouth is basically located in the center of the floor brush assembly or close to one side, so the suction generated by the suction mouth will have less influence on the edges on both sides (or the other side edge), and the reduced suction cannot form an effective wind speed flow , the dust on the edge cannot be effectively cleaned. In addition, the usual rolling brush assembly includes a rolling brush body, bristles arranged on the rolling brush body, and a motor that drives the rolling brush body to rotate. Now the conventional rolling brush assembly , The end cover of the roller brush and the body of the roller brush are in a state of relative motion. In order to keep them from rubbing against each other, there is a certain gap between the tw...
