Dust cup assembly and handheld cleaner having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld cleaners with negative pressure devices have bulky designs, making them inconvenient for handholding and difficult to disassemble for maintenance, and existing designs often encircle the negative pressure device with a dust collecting chamber, complicating disassembly and maintenance.
Innovation Solution
A compact dust cup assembly with a central chamber, dedusting chamber, and dust collecting chamber configuration, where the negative pressure device is primarily housed in the mounting chamber, and a dedusting device is used to remove dust from the airflow, facilitating disassembly and maintenance, and a handheld cleaner with a handle assembly for easy handholding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the negative pressure device is provided inside the handle, then the handheld cleaner can function properly, but the handle volume and weight increase making it inconvenient for handholding
Solution Approach 1:
The patent divides the handheld cleaner into separate modular components: the dust cup assembly (containing the negative pressure device) can be detached from the handle assembly. This segmentation allows the heavy negative pressure device to be separated from the handheld portion, reducing handle weight while maintaining complete cleaner functionality when assembled.
2Device complexity
If the negative pressure device is encircled by a dust collecting chamber, then the structure is compact, but the negative pressure device becomes difficult to disassemble for maintenance
Solution Approach 1:
The patent segments the dust cup assembly into distinct components: the dust collecting chamber and the negative pressure device are separate modules that can be independently accessed. The dust cup can be detached to expose the negative pressure device, allowing maintenance without dismantling the entire structure, thus maintaining compactness while enabling easy repair.
Solution Approach 2:
The patent implements a dynamic, multi-state structure where the dust cup assembly can transition between assembled (compact) and disassembled (maintenance-accessible) states. The dust cup serves as a removable cover that can be opened or detached, dynamically changing the accessibility of the negative pressure device while maintaining structural compactness during operation.
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
The compact design enhances user comfort and ease of use while allowing for efficient disassembly and maintenance, improving the overall performance and usability of the handheld cleaner.
Implementation Method 1
a negative pressure device, in which at least a majority of the negative pressure device is provided in the mounting chamber and used to suck airflow from the environment into the casing
Implementation Method 2
the dedusting device includes a plurality of cyclones provided around the air exhaust chamber and located directly above the dust collecting chamber
