Floor brush module and dust collector

Abstract

The invention discloses a floor brush module. The floor brush module comprises a floor brush body; a front support wheel, a front rolling brush, a back rolling brush and a back support shell are orderly arranged on the floor brush body from front to back; the floor brush module is constructed to possess a first working state and a second working state adapted to different to-be-cleaned faces; whenthe floor brush module is at the first working state, the front support wheel and the back support wheel in a high state are supported on the surface of the first to-be-cleaned face; when the floor brush module is at the second working state, the front support wheel is sunken into the second to-be-cleaned face, the back support wheel in a low state is supported on the surface of the second to-be-cleaned face; the difference between the distance from the back rolling brush to the surface of the first to-be-cleaned face in the first working state and the distance from the back rolling brush tothe surface of the second to-be-cleaned face is not more than 1 / 50 of the semi-diameter of the back rolling brush. The floor brush module not only can reduce the motor cost of the back rolling brush,but also can guarantee the airtightness adjacent to a sucker. The invention further discloses a dust collector.

Description

technical field [0001] The invention relates to a floor brush assembly, in particular to a floor brush assembly with double roller brushes. The present invention also relates to a vacuum cleaner comprising the above ground brush assembly. Background technique [0002] At present, the common double-roller floor brushes on the market often do not have a specific adjustment for changes in the working environment (floor / carpet) to achieve a better dust absorption effect. In addition, compared with the single-roller brush structure, the double-roller brushes have a high load on the floor brush rollers when working on carpets. The conventional method is to increase the motor model to provide higher torque, which makes their floor brushes have certain limitations and causes cost. rise. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a floor brush assembly and a vacuum cleaner in which the ground clearance of the rear ...

[0002] At present, the common double-roller floor brushes on the market often do not have a specific adjustment for changes in the working environment (floor / carpet) to achieve a better dust absorption effect.

In addition, compared with the single-roller brush structure, the double-roller brushes have a high load on the floor brush rollers when working on carpets. The conventional method is to increase the motor model to provide higher torque, which makes their floor brushes have certain limitations and causes cost. rise
