Rotating Clearing Roller for Floor Cleaner Brush Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaners, including vacuum cleaners and manual tools, struggle to effectively remove waste and stains firmly attached to the cleaning roller, leading to a decrease in cleaning efficiency over time due to the deformation of baffle plates used for clearing purposes.
Innovation Solution
A cleaning mechanism featuring a rotation body with strip-shaped or hair brush clearing elements that rotate in the same direction as the cleaning roller, providing stable and reliable trash removal by direct contact with the roller's surface, reducing resistance and maintaining effectiveness even after long-term use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a baffle plate is used to clear trash from the cleaning roller, then trash removal function is provided, but the baffle plate deforms after long term use, greatly decreasing the clearing effect
Solution Approach 1:
The patent transforms the stationary baffle plate into a dynamic clearing roller that rotates in the same direction as the cleaning roller. This dynamic structure maintains consistent contact pressure and clearing effectiveness throughout its service life, eliminating the deformation problem of fixed baffle plates.
Solution Approach 2:
The clearing roller is driven by the rotation of the cleaning roller itself through friction contact, without requiring an additional motor. The cleaning roller's rotation automatically drives the clearing roller to rotate, making the system self-powered and maintaining reliable clearing function throughout operation.
2Reliability
If clearing elements are disposed on a rotation body to clear the cleaning roller, then stable and reliable connection mode is achieved, but device complexity increases
Solution Approach 1:
The patent combines the clearing function with the existing cleaning roller system by using the cleaning roller's rotation to drive the clearing roller. The clearing elements are integrated on the clearing roller which rotates alongside the cleaning roller, merging two functions into a coordinated system without requiring separate complex mechanisms.
Solution Approach 2:
The clearing roller is self-driven by the friction contact with the rotating cleaning roller. No additional motor or complex drive mechanism is needed - the cleaning roller's own rotation automatically powers the clearing roller, simplifying the overall device structure while maintaining reliable operation.

AI summary
A structure for clearing a cleaning roller, and a floor cleaner. The clearing structure comprises a cleaning roller (210), a clearing mechanism (220), and a clearing power device. The clearing mechanism (220) comprises a rotating body (221) and several clearing members (222) acting on a surface of the cleaning roller (210). The clearing power device drives the rotating body (221) and clearing members (222) to rotate in the same direction as the cleaning roller (210), and the clearing members (222) can remove waste on the cleaning roller (210) during rotation.
