Sweeping robot high in dust collection amount

Abstract

The invention relates to a household automatic cleaning device, in particular to a sweeping robot. The sweeping robot comprises a shell, the shell comprises an upper shell body and a lower shell body,the side wall of the lower shell body is sleeved with the side wall of the upper shell body, and a dust collection box installation hole is formed in the center of the upper shell body. A dust collection box comprises an upper base, a lower base and an extensible cavity which is formed between the upper base and the lower base, wherein the upper base is detachably installed at the dust collectionbox installation hole, and the lower base is detachably installed in the middle of the lower shell body. Sleeve connection mechanisms are symmetrically arranged on the two sides of the dust collection box, and the sleeve connection mechanisms are connected with lifting driving devices. In the sweeping robot, the upper shell body and the lower shell body which can ascend and descend relative to each other are adopted, and the flexible extensible cavity is adopted, in the long-term using process, the cavity can be stretched and compressed through ascending and descending of the upper and lowershell bodies so as to control the density and volume of accumulated dust, the dust cleaning requirements of a long-term uninhabited house are met, on the basis, a user can properly keep indoor air circulation, and the quality of indoor air is 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.

In reality, there is a usage scenario of buying properties in different places. The user is not at home for a long time and cannot be cleaned effectively. If the doors and windows are closed for a long time, the air quality in the house will be poor, the moisture circulation will not be smooth, and a musty smell will be generated. Leaving small gaps in the doors and windows for ventilation If it is not cleaned for a long time, it will cause dust accumulation in the house. When the user returns home, it needs to be cleaned for a long time, which is time-consuming and laborious.
