Title:
MULTI-SURFACE CONTACT CLEANING ROLLER MECHANISM AND CLEANING APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2023/221254
Kind Code:
A1
Abstract:
Disclosed in the present invention are a multi-surface contact cleaning roller mechanism and a cleaning appliance. The multi-surface contact cleaning roller mechanism and the cleaning appliance comprise a cleaning roller, and a contact water squeezing strip and a water diversion strip that form a cleaning surface with the cleaning roller. The cleaning roller mechanism further comprises first pressing plates that are in contact with the surface of the cleaning roller to form first contact surfaces, and a second pressing plate that forms a second contact surface. When the cleaning roller works, at least two contact surfaces are formed on the surface to support the cleaning roller, and the contact surfaces of the cleaning surface of the cleaning roller pass through the extension line of the axis of the cleaning roller and are located within angles formed among two first pressing plate and the second pressing plate, and the axis. Therefore, according to the present invention, it can be avoided that the load of a rotating shaft is too large due to the fact that the stress of the rotating shaft in a vertical direction is increased when the surface is stressed unevenly during working of the cleaning roller, and thus, the radial stress is more uniform, thereby reducing vibration of the cleaning roller deviating from the axis during high-speed rotation.
