Handheld Cleaner Dust Cup Assembly with Removable Dedusting Device
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 cup body with a cleaner cover that can be opened and closed, and a negative pressure device integrated within, enabling the dedusting device to be withdrawn for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the dedusting device is fixed inside the device body, then the structural integrity is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The handheld cleaner is divided into separate modules: the dust cup assembly and the handle assembly can be detached from each other. The dedusting device is further segmented as a removable component within the dust cup assembly, allowing it to be taken out for cleaning while the main body remains intact.
Solution Approach 2:
The dedusting device is designed to be extractable from the dust cup assembly. The dust cup assembly itself can be detached from the handle assembly, enabling the dedusting device to be easily removed for cleaning purposes without damaging the overall structure.
2Device complexity
If the dedusting device is fixed inside the device body, then the device complexity is reduced, but the ease of repair deteriorates
Solution Approach 1:
The device is segmented into modular components that can be independently accessed and replaced. The dedusting device is a separate removable component, and the dust cup assembly is another detachable module, simplifying repair procedures.
Solution Approach 2:
The dedusting device can be extracted from the dust cup assembly for replacement or maintenance. The dust cup assembly can also be detached from the handle assembly, enabling easy repair of individual components without disassembling the entire device.
3Reliability
If the cleaner cover is permanently sealed, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The cleaner cover transitions from a permanently sealed state to a dynamic, detachable state. The cover can be opened and closed as needed, providing both sealing reliability during operation and ease of access when cleaning is required.
Solution Approach 2:
The cleaner cover is designed as a separate detachable component rather than a permanent seal. This segmentation allows the cover to be removed for cleaning the interior while maintaining structural integrity and sealing when attached.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for convenient cleaning of the dedusting device, preventing dust accumulation and bacterial growth, thereby improving the overall cleaning efficiency and reducing pollution.
Implementation Method 1
a negative pressure device provided in the cup body and used to suck airflow from an environment into the casing
