Dust collection floor brush and dust collector provided with same

Abstract

The invention provides a dust collection floor brush. The dust collection floor brush comprises a floor brush shell and a rolling brush assembly arranged on the floor brush shell, wherein the rollingbrush assembly comprises a first rolling brush and a second rolling brush which are arranged at an interval, an air inlet is arranged in the bottom of the dust collection floor brush, and the air inlet is positioned between the first rolling brush and the second rolling brush. The dust collection floor brush further comprises an air channel limiting structure connected to the floor brush shell, the air channel limiting structure comprises a limiting part downwards extending along the circumferential direction of the second rolling brush from the floor brush shell, a main air channel positionedat the downstream of airflow is formed between the floor brush shell and the second rolling brush, a dust throwing hole positioned at the upstream of airflow and realizing space limiting relative tothe main air channel is formed between the limiting part and the air inlet, and dust-containing airflow passes through the dust throwing hole from the air inlet and is discharged from an air outlet positioned at the rear side of the second rolling brush through the main air channel. With the structure, the dust separation power of the first rolling brush and the second rolling brush can be effectively promoted, so that garbage is effectively separated and smoothly guided to the air outlet, meanwhile, the vacuum degree and garbage separation efficiency are improved, and further, the dust collection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of cleaning appliances, in particular to a dust-absorbing floor brush for a vacuum cleaner and a vacuum cleaner with the same. Background technique [0002] A vacuum cleaner is a cleaning appliance used to remove dust from floors, carpets, walls, furniture, clothing and various crevices. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body of the vacuum cleaner. The suction pipeline includes a suction head, a suction pipe and a suction hose. The head has a suction port opening downwards and communicates with the air inlet of the fan inside the vacuum cleaner body through a dust suction pipe and a dust suction hose. [0003] The roller brushes of existing vacuum cleaners generally include two types, single roller brush and double roller brush. The rotation direction of the wheels is the sam...
