Dust cup, dust cup assembly and handheld cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld cleaners with negative pressure devices often have bulky designs, making them inconvenient to hold and difficult to disassemble for maintenance, and existing solutions with negative pressure devices in cup casings are not easily removable.
Innovation Solution
A dust cup design with a non-closed annular cross section and a mounting space for the negative pressure device, allowing for easy disassembly and maintenance, featuring a cup casing with an arc-shaped plate and a chamber-partition wall to isolate dust collecting chambers and facilitate the mounting of the negative pressure device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the negative pressure device is provided inside the handle, then the cleaner can function properly, but the handle volume and weight increase making it inconvenient to hold
Solution Approach 1:
The negative pressure device is extracted from the handle and relocated to the dust cup. Specifically, the negative pressure device is mounted in the mounting space defined between the inner-ring wall face of the cup casing and the top wall of the base, with the mounting space being opened at the top and side to facilitate access and disassembly. This extraction reduces handle weight and improves ergonomics while maintaining cleaner functionality.
2Weight of moving object
If the negative pressure device is provided in the cup casing, then the handle weight is reduced, but the device becomes difficult to disassemble and maintain
Solution Approach 1:
The dust cup is segmented into multiple components: the base, the cup casing with non-closed annular cross section, and the mounting space with open top and side. The negative pressure device is mounted in the mounting space which is accessible through the opened portions, allowing easy disassembly and maintenance while maintaining compact integration.
3Device complexity
If the cup casing has a non-closed annular cross section, then the structure is simplified and accessibility is improved, but the dust collecting chamber configuration becomes more complex
Solution Approach 1:
The cup casing transitions from a traditional closed cylindrical form to a non-closed annular cross-section structure. This dimensional change creates a mounting space between the inner-ring wall face and the top wall of the base, allowing the negative pressure device to be mounted with open access from the top and side, thereby simplifying the overall structure and improving accessibility.
