Hand-guided cyclone vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld cyclone vacuum cleaners have central filters that are not accessible during operation, requiring users to disassemble the entire separation system for cleaning, leading to handling difficulties and reduced performance.
Innovation Solution
A handheld cyclone vacuum cleaner design with a rotatable lid and integrated cleaning mechanism allows direct access to the central filter during operation, enabling cleaning without detachment from the appliance body, and includes a locking mechanism to prevent dirt from entering the drive unit during filter removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the central filter is integrated into the separator housing, then the separator structure is simplified, but the filter becomes inaccessible during operation requiring full disassembly for cleaning
Solution Approach 1:
The patent divides the filter assembly into separable components: the filter element remains integrated in the separator housing for structural simplicity, while a removable cover allows access to the filter. This segmentation enables the filter to be cleaned by simply removing the cover rather than disassembling the entire separator, resolving the contradiction between structural simplicity and operational accessibility.
2Ease of operation
If the filter is made easily accessible for cleaning, then maintenance convenience is improved, but the risk of dirt entering the drive unit increases
Solution Approach 1:
The patent introduces a cover as an intermediary component between the filter and the drive unit. This cover can be removed for filter access but includes features to prevent dirt from reaching the drive unit during removal or installation. The cover acts as a mediator that enables filter maintenance while protecting the drive unit from contamination, resolving the contradiction between accessibility and contamination risk.
3Object-affected harmful factors
If the filter requires full separator disassembly for cleaning, then internal component protection is improved, but user time and effort increase
Solution Approach 1:
By segmenting the filter assembly into a permanent filter element and a removable cover, the patent enables cleaning without full separator disassembly. The cover can be quickly removed and reattached, dramatically reducing cleaning time while the separator remains assembled to protect internal components. This resolves the contradiction between protection and time investment.
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
Enhances user convenience by allowing on-the-go cleaning, minimizes malfunctions, extends the vacuum cleaner's service life, and maintains performance by preventing contamination of internal components.
Implementation Method 1
the airflow entering the vacuum cleaner creates vortices and turbulence. This causes the vacuumed material, such as dust particles, to be forced in a predetermined direction by centrifugal force and separated in a separator within the vacuum cleaner
Implementation Method 2
handheld cyclone vacuum cleaner... airflow entering the vacuum cleaner creates vortices and turbulence

AI summary
The invention relates to a handheld cyclone vacuum cleaner comprising: - a separator (1) comprising a housing (19), a central filter (2) arranged in the housing (19), and a rotatable cover (3); - a device body (7) with a drive unit configured to generate an airflow through the separator (1) when operating in a first state of the handheld cyclone vacuum cleaner, in which the separator (1) and the device body (7) are detachably connected to one another, wherein an intake area of the drive unit is arranged downstream of the airflow to the central filter (2), wherein the central filter (2) can be cleaned in the first state by rotating the rotatable cover (3), and in a second state of the handheld cyclone vacuum cleaner, in which the separator (1) and the device body (7) are detached from one another, when the rotatable cover (3) is rotated in a predetermined direction of rotation out of the housing. (19) can be removed.
