Removable Dust Cup Filtration for Hygienic Handheld Vacuum Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld cleaners often have dedusting devices that are difficult to clean, leading to residual dust and bacterial growth, which reduces their effectiveness and causes secondary pollution.
Innovation Solution
A dust cup assembly with a removable dedusting device and a negative pressure system that allows for easy cleaning, featuring a casing with a detachable cleaner cover and a design that separates airflow paths for efficient dust collection and filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dedusting device is fixed inside the device body, then the structure is compact and simple, but the user cannot remove it to clean it, causing residual dust and bacterial growth
Solution Approach 1:
The dust cup assembly is divided into multiple detachable components: the dust cup body, the cleaner cover, and the dedusting device. This segmentation allows the dedusting device to be easily removed from the cup body for cleaning, while maintaining a compact integrated structure during operation. The detachable connection enables users to access and clean the dedusting device without disassembling the entire assembly.
Solution Approach 2:
The dedusting device is designed to be extractable from the cup body through the detachable cleaner cover mechanism. This extraction capability allows users to remove the dedusting device for cleaning and maintenance, solving the problem of inaccessible residual dust while keeping the overall structure relatively simple through standardized connection interfaces.
2Reliability
If the dedusting device is fixed inside the device body, then the structure is simple, but residual dust causes bacterial growth and secondary pollution
Solution Approach 1:
By segmenting the dust cup assembly into detachable components, the dedusting device can be separated from the cup body for thorough cleaning. This ensures residual dust is completely removed and prevents bacterial growth, while the segmentation uses simple connection mechanisms that minimize structural complexity.
Solution Approach 2:
The detachable design enables users to easily clean the dedusting device themselves without requiring specialized tools or disassembly procedures. Users can remove the device, clean it with water or compressed air, and reattach it, ensuring maintained hygiene and preventing secondary pollution from residual dust.
3Ease of operation
If the cleaner cover is made detachable for easy cleaning, then cleaning convenience is improved, but the sealing and air tightness may be compromised
Solution Approach 1:
The cleaner cover is designed with pre-positioned sealing elements and alignment features that ensure proper sealing when attached. The sealing structure is prepared in advance during manufacturing, with gaskets or sealing rings pre-installed in the correct positions, ensuring that the detachable design does not compromise sealing performance.
Solution Approach 2:
The sealing mechanism replaces complex mechanical interlocking systems with simpler friction-fit or snap-fit connections combined with elastic sealing elements. This substitution maintains air tightness while enabling easy detachment and reattachment of the cleaner cover for cleaning purposes.
