Cleaning Roller Clearing Mechanism With Rotating Brush Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners fail to effectively remove waste and stains firmly attached to the ground due to the limitations of their working principle, and the baffle plates used in newer cleaners tend to deform over time, reducing their clearing effectiveness.
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 without the need for fixed baffle plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed baffle plate is used to clear trash from the cleaning roller, then the clearing function is initially effective, but the baffle plate deforms over time and clearing effectiveness greatly decreases
Solution Approach 1:
The patent transforms the static baffle plate into a dynamic rotating body with clearing elements that rotate in the same direction as the cleaning roller. This dynamic structure adapts to the roller's motion, maintaining consistent contact and clearing effectiveness without deformation. The rotating clearing elements continuously engage with the cleaning roller surface, preventing the degradation issues of fixed structures.
Solution Approach 2:
The patent divides the single large baffle plate into multiple smaller clearing elements distributed around the rotating body. This segmentation allows each clearing element to independently maintain optimal contact with the cleaning roller, reducing stress concentration and preventing the deformation that occurs in large fixed plates. The segmented structure provides redundancy and maintains clearing function even if individual elements wear.
2Productivity
If conventional vacuum cleaners are used to remove waste and stains, then they operate through negative pressure, but they fail to eliminate waste and stains firmly attached to the ground
Solution Approach 1:
The patent merges the functions of the cleaning roller and the clearing mechanism into a single integrated system. The clearing elements are disposed on a rotating body that works in conjunction with the cleaning roller, combining the cleaning and clearing functions. This integration ensures that waste is both picked up by the cleaning roller and effectively cleared off, solving the limitation of vacuum cleaners that cannot remove firmly attached waste.
Solution Approach 2:
The rotating body with clearing elements serves as an intermediary mechanism between the cleaning roller and the waste collection system. This intermediary actively engages with the cleaning roller surface to scrape and remove firmly attached waste, bridging the gap between the vacuum's suction capability and the need for mechanical waste removal from the roller surface.

AI summary
A cleaning mechanism for clearing a cleaning roller of a cleaner. The cleaning mechanism includes: a cleaning roller for cleaning ground, a clearing component operating to clearing the cleaning roller, and a power unit. The clearing component includes a rotation body and a plurality of clearing elements disposed on the rotation body for clearing a surface of the cleaning roller. The power unit operates to drive the rotation body and the clearing elements to rotate along with the cleaning roller in the same direction. During the rotation of the cleaning roller, the trash is cleared by the clearing elements.
