Roller floor brush used for dust collector

Abstract

The invention discloses a roller floor brush used for a dust collector, which comprises a strip-shaped floor brush body with an internal cavity and a connection tube arranged on the floor brush body in a rotatable mode, wherein the floor brush body comprises a cylindrical left side part, a cylindrical right side part and a middle part positioned between the left side part and the right side part, the circumferential surfaces of the left side part and the right side part are respectively sleeved with a roller, the central line of the roller rolling on the floor brush body coincides with a cylindrical axis line and extends along the directions of the left and the right sides of the floor brush body, the rotation axis line of the connection tube arranged on the floor brush body in a rotation mode also extends along the directions of the left side and the right side of the floor brush body, the direction of the rotation axis line of the connection tube is deviated from the direction of the cylindrical axis line, and then when the connection tube swings up and down to collect dust, the floor brush body can be prevented from being overturned under the driving of the up and down swing of the connection tube, so a dust collection port at the bottom of the floor brush body is always oriented to the surface on which dust is collected, and the dust collection efficiency is increased.

Description

technical field [0001] The invention relates to a roller floor brush for a vacuum cleaner. Background technique [0002] In the prior art, a roller floor brush for a vacuum cleaner includes a floor brush body with an inner cavity, the floor brush body is cylindrical, and a roller is set on the outside of the floor brush body, and the roller rolls around the central axis of the floor brush body. There are a plurality of strip-shaped brush blocks protruding evenly along its circumference. When the roller rolls, the brush blocks clean the surface to be cleaned and collect dust and other sundries. There is suction between two adjacent brush blocks along the circumference of the drum. Dust mouth, the bottom of the ground brush body is also provided with a dust suction port, when the ground brush works like this, the debris collected by the brush block is sucked by the dust suction port and enters the inner cavity of the ground brush body. The top of the ground brush body is prov...

AI Technical Summary

Problems solved by technology

The top of the ground brush body is provided with a connecting pipe that can rotate up and down. The connecting pipe is connected with the handle. When they coincide, the lumen, inner cavity, and suction port of the connecting pipe are connected to form a dust suction channel, and the sundries are removed through the dust suction channel. The axis line coincides with the axis line of the nozzle rotation, so that when the handle is operated, the up and down rotation of the nozzle will easily drive the floor brush body to turn over, so that the suction port at the bottom of the floor brush body will be far away from the surface to be cleaned, reducing the dust collection efficiency
