Vacuum Cleaner Filter Interlock and Dual-Action Cleaning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners lack a mechanism to ensure proper installation of the filter assembly before allowing the dirt cup to be secured, potentially leading to inadequate filtration and reduced cleaning efficiency.
Innovation Solution
A filter interlock mechanism that physically prevents the installation of the dirt cup if the filter assembly is not installed, ensuring that the filter is in place before the dirt cup can be locked into position, combined with a filter cleaning mechanism that uses rotational flicking and vertical shaking to extend the life of the filters and prevent clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter interlock mechanism is added to prevent dirt cup installation without filter assembly, then filtration reliability is improved, but device complexity increases
Solution Approach 1:
The filter interlock mechanism performs a preliminary check to ensure the filter assembly is installed before allowing the dirt cup to be secured. The interlock mechanism includes a filter assembly detection feature that must be engaged before the dirt cup latch can lock, preventing operation without proper filtration in place.
Solution Approach 2:
The filter interlock mechanism acts as an intermediary between the filter assembly and the dirt cup installation process. It includes intermediate components such as a detection lever and latch interaction features that mediate the coupling between these two components, ensuring proper filter installation as a prerequisite for dirt cup securing.
2Ease of repair
If a filter cleaning mechanism with rotational flicking and vertical shaking is added, then filter maintenance effectiveness is improved, but device complexity increases
Solution Approach 1:
The filter cleaning mechanism utilizes mechanical vibration through rotational flicking and vertical shaking motions. A cleaning arm rotates to flick debris from the filter surface, while vertical shaking movements dislodge accumulated particles, effectively cleaning the filter without requiring disassembly or manual intervention.
Solution Approach 2:
The filter cleaning mechanism enables the filter assembly to clean itself automatically during vacuum operation or idle periods. The self-cleaning function reduces maintenance burden by eliminating the need for manual filter cleaning, allowing the filter to restore its own performance without user intervention.

AI summary
A vacuum cleaner includes an improved dual-action filter cleaning mechanism using both a rotational flicking action and a vertical shaking action. A debris removal assembly of the vacuum cleaner can include a filter assembly having a first filter and a second filter arranged in a nested configuration, and a filter cleaning mechanism configured to impart a combination of vertical shaking of the first filter and rotational flicking of the second filter. The filter cleaning mechanism can include a camming mechanism configured to simultaneously move the first filter along the axis and rotate the first filter about the axis while the second filter remains stationary.
