Long-time clearing-free floor sweeping robot

Abstract

The invention relates to automatic home cleaning devices, in particular to a floor sweeping robot. A movable sleeving shaft is arranged between an upper shell and a lower shell of the floor sweeping robot, a lifting driving device for driving the sleeving shaft to be lifted so as to change the relative height between the upper shell and the lower shell is arranged at the sleeving shaft, a dust collecting box comprises an upper seat, a lower seat and a flexible cavity capable of being pulled up, the upper seat is arranged in the upper shell, the lower seat is arranged in the lower shell, the flexible cavity is arranged between the upper seat and the lower seat, and the upper seat can be driven by the upper shell to upwardly move to pull up the cavity along with long-time use, so that the capacity of the cavity can be improved. The floor sweeping robot has the advantages that the floor sweeping robot comprises the upper shell, the lower shell and the flexible cavity capable of being pulled up, the upper shell and the lower shell can be relatively lifted, stretching and compressing can be carried out under lifting actions on the upper shell and the lower shell to control the density of accumulated dust and the capacity for the accumulated dust in long-term use procedures, accordingly, dust clearing requirements of long-term unoccupied houses can be met, indoor air circulation canbe appropriately kept by users on the basis, and the indoor air quality can be improved.

Description

technical field [0001] The invention relates to a household automatic cleaning device, in particular to a sweeping robot. Background technique [0002] With the improvement of people's living standards, sweeping robots have entered more and more families. The existing sweeping robots can realize automatic cleaning, automatic path planning, and automatic return to the charging stand for charging, which brings convenience to people's lives. The basic structure of existing sweeping robots generally includes a housing, a walking wheel assembly located at the lower part of the housing, a cleaning assembly, and a dust collection box located inside the housing. Most of the dust collection boxes of existing sweeping robots are fixed structures. At the bottom or side of the housing, it is a capacity-fixed structure when in use.
