Cyclone Dust Collector Grill Rotation to Prevent Suction Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclone dust collectors in vacuum cleaning devices face issues with reduced inhalation force due to clogged air through holes in the grill part, requiring manual dust removal, which is inconvenient and affects cleaning efficiency.
Innovation Solution
A rotatable grill assembly integrated with a fan system, where the grill is mounted on a rotatable fan case and supported by ribs, with a second fan generating an opposing air current to prevent dust accumulation and facilitate easy dust removal through centrifugal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grill is stationary in the outlet part, then the structure is simple, but dust accumulates on the outer circumferential surface causing air through holes to clog and inhalation force to lower
Solution Approach 1:
The grill is changed from a stationary component to a rotatable one, driven by the cyclone flow of air. This dynamic design allows the grill to automatically rotate and prevent dust accumulation on its outer circumferential surface, maintaining air through hole畅通 and consistent inhalation force without requiring manual intervention
Solution Approach 2:
The grill utilizes the cyclone flow of air already present in the system to drive its own rotation. The air flow serves dual purposes: both filtering dust through the grill and providing the rotational motion needed to prevent dust accumulation, eliminating the need for external driving mechanisms or manual cleaning
2Reliability
If the grill rotates automatically, then dust accumulation is prevented and inhalation force is maintained, but the device complexity increases
Solution Approach 1:
The grill rotation is powered by the cyclone flow of air that already exists in the dust collecting unit. The air flow naturally drives the grill to rotate without requiring external motors, gears, or complex drive mechanisms, thus maintaining system simplicity while achieving automatic dust removal
Solution Approach 2:
The cyclone flow of air performs multiple functions simultaneously: it filters dust through the grill, drives the grill rotation to prevent dust accumulation, and maintains the overall cleaning operation. This multi-functionality eliminates the need for separate components for each function, reducing overall device complexity
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 solution maintains a consistent inhalation force by preventing dust accumulation on the grill surface, allowing for efficient cleaning without manual dust removal and extending the maintenance interval of the fine filter.
Implementation Method 1
the grill may be rotated by an inhalation force
Implementation Method 2
The second fan may be disposed at an outer circumference of the first fan... When the fan rotates, the second fan may extend so that air is introduced into the cyclone chamber through the outlet part

AI summary
In a cyclone dust collector (40) and a vacuum cleaning device (1) having the same, foreign substances can be prevented from being attached on an outer circumferential surface of a grill (63) located at an outlet part (85), so that an inhalation force of the vacuum cleaning device (1) can be prevented from being lowered. Also, foreign substances collected in the cyclone dust collector (40) can be easily removed. The vacuum cleaning device (1) includes: a cyclone dust collector (40), wherein the cyclone dust collector (40) includes: a cyclone chamber (53) in which air introduced through an inlet part (56) is whirled and dust is separated from the air; an outlet part (85) disposed so that the air from which the dust is separated is discharged from the cyclone chamber (53); and a grill (63) that is rotatably disposed in the outlet part (85).
