Clearing device, base station, cleaning device system, and method for clearing rolling brush assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot vacuum cleaners face challenges in effectively clearing tangles from the roller brush without damaging the brush structure, as existing methods often result in incomplete removal and potential damage during the cleaning process.
Innovation Solution
A cleaner system comprising a feeder and a cutter with a clearing controller, where the feeder moves the tangles from a pick-up position to a working position, and the cutter, with reciprocating shearing members, cuts the tangles while maintaining a safe distance from the roller brush to prevent damage, ensuring effective removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing cleaning methods (comb teeth, blade, serrations) are used to clear tangles from the roller brush, then the tangles can be cut or removed, but the roller brush structure is easily damaged and tangles adhering in clusters cannot be effectively cleared
Solution Approach 1:
The feeder performs preliminary action by pulling tangles away from the roller brush surface before the cutter acts on them. The feeder moves tangles from the pick-up position to the working position, separating them from the brush structure, which prevents damage during the subsequent cutting operation.
Solution Approach 2:
The feeder acts as an intermediary between the roller brush and the cutter. It transfers tangles from the brush to the cutter's working position, enabling the cutter to remove tangles without directly contacting and damaging the roller brush structure.
2Productivity
If the cutter is positioned close to the roller brush to effectively cut tangles, then cutting effectiveness improves, but the risk of damaging the roller brush structure increases
Solution Approach 1:
The feeder performs preliminary action by pulling tangles away from the roller brush surface before the cutter acts on them. The feeder moves tangles from the pick-up position to the working position, separating them from the brush structure, which prevents damage during the subsequent cutting operation.
Solution Approach 2:
The feeder acts as an intermediary between the roller brush and the cutter. It transfers tangles from the brush to the cutter's working position, enabling the cutter to remove tangles without directly contacting and damaging the roller brush structure.
3Reliability
If the feeder moves tangles to a working position farther from the roller brush axis, then the cutter can maintain safe distance and prevent damage, but the complexity of the clearing mechanism increases
Solution Approach 1:
The feeder serves multiple functions: it pulls tangles from the roller brush surface, transports them to the working position, and positions them for cutting. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall mechanism complexity despite the additional movement capability.

AI summary
The present disclosure relates to a cleaner and a base station. A driving unit is utilized to drive a feeder to move to a pick-up position, and then to a working position from the pick-up position, so that tangles on a roller brush are pulled down. When the tangles are pulled down, a cutter cuts the tangles such that the roller brush is effectively cleared. Therefore, a cutting mode of the cleaner is to pull the tangles first and then cut the tangles, which can ensure the tangles that adhere to the roller brush in clusters to leave the roller brush in time after the tangles are cut off such that the tangles can be effectively cleared away.
