Document Type and Number:
WIPO Patent Application WO/2023/173568
Kind Code:
A1
Abstract:
A lower casing assembly (10) and a cleaning device (1). The lower casing assembly (10) comprises: a lower casing body (100), a first module (630) and a second module (640), the lower casing body (100) comprising a bottom portion (600) and a side portion (610); the bottom portion (600) comprising a first side (601) and a second side (602) which are opposite to each other; the side portion (610) being arranged around the bottom portion (600) so as to form a cavity (603) in the first side (601) of the bottom portion (600); the first module (630) being mounted on the second side (602) of the lower casing body (100); the second module (640) being mounted on the second side (602) of the lower casing body (100) and being spaced apart from the first module (630); the first module (630) being configured to rotate around a rotation axis (678); the second module (640) being configured to rotate around an axis perpendicular to the rotation axis (678); and the rotation axis (678) extending in a direction in which the first side (601) points at the second side (602). The lower casing assembly (10) and the cleaning device (1) can combine a cleaning effect and an advancing speed of the cleaning device (1), and not only comprise a module capable of realizing rapid linear advancing of the cleaning device (1), but also comprise a module capable of performing cleaning by means of rotation, so that the cleaning efficiency of the cleaning device (1) is remarkably improved while ensuring the moving speed of the cleaning device (1).
