Portable Vacuum Cleaner Two-Way Locking for Single-Step Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners require cumbersome and error-prone multi-step processes for opening the dust blocking cover and separating the dust scraping cylinder from the main body, leading to inefficient dust cleaning and operator contamination.
Innovation Solution
A portable vacuum cleaner with a two-way locking mechanism that allows simultaneous opening of the dust blocking cover and separation of the dust scraping cylinder from the main body, reducing the operation process to a single step and enhancing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional multi-step disassembly process is used for opening dust blocking cover and separating dust scraping cylinder, then operational reliability is maintained, but ease of operation deteriorates and time consumption increases
Solution Approach 1:
The patent combines the dust blocking cover opening action with the dust scraping cylinder separation action into a single integrated operation. When the user opens the dust blocking cover, the dust scraping cylinder automatically separates from the main body through the integrated linkage mechanism, reducing multiple discrete steps into one unified action that simultaneously achieves both functions.
Solution Approach 2:
The patent employs a pre-configured linkage mechanism between the dust blocking cover and the dust scraping cylinder. The locking and guiding structures are预先 (pre) arranged so that when the cover is opened, the connected components automatically follow the predetermined path for separation, eliminating the need for users to manually perform multiple sequential disassembly steps.
2Productivity
If frequent disassembly and assembly of dust cup and filter is performed, then dust cleaning function is maintained, but reliability deteriorates due to loose fit and reduced service life
Solution Approach 1:
The patent merges the dust cup, filter, and dust scraping cylinder into an integrated assembly that moves together as a single unit. This combined structure ensures that all components maintain their relative positions and connections during repeated assembly and disassembly operations, preventing the loose fit and connection issues that occur when components are handled separately.
3Ease of operation
If manual disassembly of dust cup and filter is required, then dust cleaning capability is maintained, but ease of operation deteriorates due to cumbersome process and contamination risk
Solution Approach 1:
The patent combines the dust blocking cover opening mechanism with the dust scraping and cylinder separation functions into one integrated system. This allows users to access and clean the dust cup and filter through a single cover opening action without needing to manually disassemble multiple components, thereby reducing the risk of hand contamination and simplifying the operational process.

AI summary
A portable vacuum cleaner includes a housing and a filter assembly. The housing includes a dust collecting cylinder, a dust blocking cover and a main body. The dust collecting cylinder is opened to form an air inlet port and a mating port. The dust blocking cover is rotatably connected to the air inlet port of the dust collecting cylinder. The main body is detachably connected to the mating port of the dust collecting cylinder. A two-way locking structure is provided between the dust blocking cover and the main body. The two-way locking structure is adapted to lock or unlock the dust blocking cover and the main body simultaneously with the dust collecting cylinder, so that when the two-way locking structure is in a locked state, the dust blocking cover cannot open the air inlet port, while the dust collecting cylinder and the main body cannot be separated.
