Rolling brush device and cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot vacuum cleaners require multiple turnovers to mount and dismount the roller brush, making the process inconvenient and potentially causing scratches on the device.
Innovation Solution
A roller brush device with a mounting assembly that allows for rotational movement and easy access from the top or side, featuring a shielding plate, lifting portion, and air outlet to facilitate convenient mounting and dismounting without turning the device over.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the roller brush is located at the bottom of the cleaning apparatus, then the cleaning function is improved, but the ease of operation deteriorates due to requiring multiple turnovers for mounting and dismounting
Solution Approach 1:
The patent changes the access dimension for roller brush maintenance from bottom-only access to side/top access. The mounting assembly includes a side opening that allows the roller brush to be mounted and dismounted from the side of the cleaning apparatus, eliminating the need to turn the device over. This dimensional change in access path directly resolves the contradiction by improving ease of operation while reducing time loss.
2Ease of operation
If the roller brush is located at the bottom of the cleaning apparatus, then the cleaning function is improved, but the ease of operation deteriorates due to requiring multiple turnovers
Solution Approach 1:
The patent segments the mounting assembly into distinct components including a mounting rack, shielding plate, and side opening structure. This segmentation allows the roller brush to be accessed through a dedicated side access path independent of the bottom cover, simplifying the overall mounting and dismounting process by separating the access function from the main body structure.
3Object-affected harmful factors
If the roller brush is exposed at the bottom of the cleaning apparatus, then the cleaning function is improved, but harmful factors increase due to risk of scratches during turnover operations
Solution Approach 1:
The patent extracts the roller brush access function from the bottom cover area and relocates it to the side opening. By taking out the mounting and dismounting operation from the bottom turnover process, the harmful scratches that occur during repeated turning over are eliminated. The roller brush can now be accessed through the side opening without involving the bottom cover or requiring the device to be turned over.

AI summary
The present disclosure provides a roller brush device and a cleaning apparatus. The roller brush device includes a roller brush (21) and a mounting assembly. The roller brush (21) is connected with the mounting assembly. The roller brush (21) is rotatable relative to the mounting assembly, and the mounting assembly is able to drive the roller brush (21) to move. One side of the mounting assembly defines an avoidance notch (20a), and the roller brush (21) is exposed at the avoidance notch (20a).
