Solution Overview

Problem

Conventional cleaners, including vacuum cleaners, 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 to clear trash.

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 limitations of fixed baffle plates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed baffle plate is used to clear trash from the cleaning roller, then the initial clearing effect is good, but after long term use the baffle plate deforms and the clearing effect greatly decreases

Engineering Contradiction:
Improveclearing effect stabilityVSAvoidbaffle plate service life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent transforms the fixed baffle plate into a rotating clearing component that rotates in the same direction as the cleaning roller. This dynamic solution allows the clearing elements to continuously contact the cleaning roller surface, maintaining consistent clearing pressure and effect throughout operation, thereby resolving the deformation and effectiveness loss of fixed baffle plates over time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating clearing component utilizes the rotation of the cleaning roller itself to achieve relative motion for trash removal. By rotating in the same direction, the clearing elements continuously engage with the cleaning roller surface, enabling self-maintaining clearing action without requiring separate actuation mechanisms, thus ensuring long-term reliability.

Inventive Principle:
Principle #25Self-service

2Productivity

If conventional vacuum cleaners are used to adsorb waste and dust, then negative pressure cleaning is achieved, but waste and stains firmly attached to the ground cannot be eliminated

Engineering Contradiction:
Improvecleaning completenessVSAvoidfirmly attached waste removal
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent combines mechanical clearing action with the vacuum cleaning system. The rotating clearing component with clearing elements physically removes firmly attached waste and stains from the cleaning roller surface, complementing the negative pressure adsorption function, thereby achieving complete cleaning of both loose and firmly attached contaminants.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rotating clearing component performs preliminary mechanical removal of firmly attached waste and stains before the vacuum adsorption process. By pre-cleaning the cleaning roller surface, the subsequent vacuum operation can more effectively collect and remove all types of debris, improving overall cleaning completeness.

Inventive Principle:
Principle #10Preliminary action

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.
