Cyclone Vacuum Cleaner with Internal Movable Filter Cleaning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with filter cleaning accessibility, airflow resistance, and dust accumulation, particularly in handheld vacuum cleaners where the filter cleaning process is cumbersome and requires frequent manual intervention, and in automatic cleaners where the compression mechanism can act as an airflow resistor and is prone to dust contamination.
Innovation Solution
A cleaner design featuring a movable part with a cleaning mechanism that can be manipulated externally to clean the filter without surrounding it, minimizing airflow resistance and preventing dust accumulation, while also allowing for stable operation and efficient dust collection by adjusting the cyclone flow and filter geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable part surrounds the filter part at standby position, then the filter is protected, but airflow resistance increases and dust accumulation occurs
Solution Approach 1:
The movable part transitions from a static surrounding structure to a dynamic component that can move between positions. At standby position, it is retracted to minimize airflow resistance. During cleaning operation, it moves to surround and contact the filter part for effective cleaning, thus resolving the contradiction between protection and airflow resistance
Solution Approach 2:
The cleaning system is divided into separate functional components: the movable part that can independently position itself relative to the filter part. This segmentation allows the movable part to be positioned away from the filter during normal operation (reducing airflow resistance) and moved to the filter during cleaning (providing protection and cleaning functionality)
2Quantity of substance
If the compression mechanism is positioned to compress dust, then dust accumulation is reduced, but it acts as an airflow resistor
Solution Approach 1:
The compression mechanism is designed as a movable component that dynamically adjusts its position. During normal operation, it is retracted to the standby position where it does not interfere with airflow. When dust accumulation reaches a certain level, it moves to the dust container to perform compression, thus resolving the contradiction between dust management and airflow resistance
3Quantity of substance
If manual cleaning of the cover is required, then dust removal is achieved, but user accessibility and ease of operation deteriorate
Solution Approach 1:
The cleaning part is designed to automatically clean the filter part without requiring user disassembly or direct contact. The movable part moves into position and performs cleaning autonomously when activated, eliminating the need for users to manually rotate bases or open dust collectors, thus resolving the contradiction between dust removal effectiveness and ease of operation
Solution Approach 2:
The movable part acts as an intermediary cleaning mechanism between the user and the filter part. Instead of users directly cleaning the filter, the movable part performs the cleaning function, mediating the interaction and making the system easier to maintain while still achieving effective dust removal

AI summary
A cleaner includes a suction unit, a main body including a cyclone unit for separating dust from air suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit. A filter unit is disposed inside the cyclone unit for filtering the air, and a movable unit disposed inside the cyclone unit includes a cleaning part for cleaning the outer circumference of the filter unit. An operation unit disposed outside the main body moves the movable unit and the cleaning part to remove dust from the outer surface of the filter unit.
