Title:
CLEANING APPARATUS AND ROLLING BRUSH ASSEMBLY OF CLEANING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/088221
Kind Code:
A1
Abstract:
The present disclosure provides a cleaning apparatus. The cleaning apparatus comprises a chassis, and a universal wheel assembly, a rolling brush assembly, a driving wheel assembly and a squeegee assembly, which are sequentially arranged on the chassis from front to back, wherein the universal wheel assembly is configured to be arranged on the chassis by means of elastic devices; the rolling brush assembly comprises a first rolling brush and a second rolling brush, which are used for cleaning a working face and are arranged side by side from front to back; the driving wheel assembly is configured to drive the cleaning apparatus to travel on the working face; and the squeegee assembly is configured to soak up water stains on the working face. In the cleaning apparatus of the present disclosure, components on the chassis cooperate with each other and integrally form a stable supporting system; the center of gravity of each component is rationally distributed, such that the cleaning apparatus is securely supported on the working face, thereby improving the stability; in addition, the overall structure is more compact, such that the turning radius of the chassis can be reduced, thereby facilitating the cleaning of edges, corners, and narrow and small spaces by the rolling brush assembly.
