Self-propelled dust collector matched with ground lifting roller brush assembly

Abstract

The invention provides a self-propelled dust collector matched with a ground lifting roller brush assembly. The self-propelled dust collector mainly comprises a machine body and the roller brush assembly. The machine body is provided with a dust collecting box, a dust sucking device and multiple wheel bodies. The bottom wall of the machine body is recessed inwards to form a containing groove. The roller brush assembly is arranged in the containing groove. Two pivot arms of a roller brush frame of the roller brush assembly are arranged in the containing groove of the machine body in a pivoted mode. A flexible connecting part of the roller brush assembly is through to form a channel, and a second opening of the roller brush frame is communicated with a dust collecting opening of the dust collecting box through the channel of the flexible connecting part. Thus, when the machine body passes an obstacle terrain, when the roller brush frame bears the external force effect, due to the fact that the pivot arms can swing up and down, a dust collecting piece of the roller brush frame can be kept attached to the ground, and then the sweeping effect is improved.

Description

technical field [0001] The present invention is related to a self-propelled vacuum cleaner, in particular to a self-propelled vacuum cleaner with a rolling brush assembly matched with the floor. Background technique [0002] U.S. Patent No. US2014 / 0137367A1 discloses a self-propelled vacuum cleaner with an elastic lifting roller brush and its roller brush frame unit (Automatic coverage vacuum cleaner having roll ler brush capable of resi l ient vertical di placement and roll ler brush frame unit for the same), wherein the self-propelled vacuum cleaner (autonomous coverage vacuum cleaner) (figure number 10) with an elastic liftable roller brush includes a body (figure number 11). The roll brush frame unit (roller brush frame unit (figure number 13)) includes a roller brush frame (roller brush frame) (figure number 30), a connecting frame (connection frame) (figure number 40) and an elastic connection pieces (resi l ient connection element) (figure number 50). The elastic co...
