Dust Bag Support Structure for Simplified Handheld Cleaner Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld cleaning devices require manual removal of fine dust particles from the cyclone separation apparatus, which is inconvenient for users.
Innovation Solution
A supporting structure is introduced that allows for the installation of a disposable dust bag within the cleaning device, enabling easy replacement by detaching the dust bag from the device after use, with a sealing mechanism to prevent leakage during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a disposable dust bag is installed in the cleaning device, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The dust bag is nested within the dust collecting bucket, with the bag body positioned inside the bucket body. The supporting structure integrates multiple components (top structure, side structure, support legs, connecting components) that nest together to form a compact assembly within the cleaning device, allowing easy installation and removal while maintaining structural organization
Solution Approach 2:
The supporting structure is divided into multiple independent components: top structure, side structure, support legs, and connecting components. This segmentation allows each part to be manufactured separately, assembled into a complete supporting structure, and then installed as a unit in the cleaning device, simplifying both manufacturing and maintenance
2Reliability
If a sealing mechanism is added to prevent leakage during dust bag removal, then reliability is improved, but device complexity increases
Solution Approach 1:
The sealing ring is pre-installed on the dust bag opening before the dust bag is placed in the dust collecting bucket. This preliminary sealing action ensures that the sealing interface is already prepared and positioned correctly, preventing leakage during operation and removal without requiring complex active sealing mechanisms
Solution Approach 2:
A sealing ring acts as an intermediary element between the dust bag opening and the dust collecting bucket opening. This intermediary component creates a reliable seal at the interface, preventing dust leakage during removal while keeping the sealing mechanism simple and passive
3Ease of manufacture
If the dust bag is made from flexible air-permeable material, then ease of manufacture is improved, but manufacturing precision worsens
Solution Approach 1:
The dust bag is made from flexible air-permeable material for the bag body to enable ease of manufacture and adaptation, while the opening portion incorporates a sealing ring with precise dimensions. This local differentiation allows the majority of the dust bag to be manufactured simply from flexible material, while only the critical sealing interface requires precise dimensional control

AI summary
The present disclosure relates to a supporting structure and a cleaning device. The supporting structure includes a top structure and a side structure. The top structure is connected and fixed to a main body of the cleaning device. The side structure includes: a dust bag installation structure, a dust bag being fittingly installed to the dust bag installation structure through an installation assembly on the dust bag; and a support air inlet channel for communicating a dirty air inlet of the cleaning device and a dust bag inlet.
