Cyclone Dust Collector Upper Cover Noise Reduction Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone dust collectors generate noise due to air collisions with the upper cover's inner wall during air discharge, causing user discomfort.
Innovation Solution
A noise reduction part is integrated between the discharge ports of second cyclone chambers and the upper cover, comprising a noise-absorbing member and a porous grill member, which absorbs and prevents noise generation by shaping to match the inner wall and positioning between the discharge ports and the upper cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If air is discharged directly through discharge ports to the upper cover, then the structure is simple and air discharge is efficient, but noise is generated due to air collision with the inner wall
Solution Approach 1:
A noise reduction part is introduced as an intermediary component between the discharge ports and the upper cover. This part includes a noise-absorbing member that intercepts the discharged air before it reaches the inner wall, thereby reducing noise without fundamentally changing the air discharge path or requiring complex structural modifications
Solution Approach 2:
The noise-absorbing member utilizes porous material properties to absorb and dampen noise generated by air discharge. The porous structure allows air to pass through while reducing the intensity of noise waves, effectively addressing the noise problem while maintaining relatively simple device architecture
2Object-affected harmful factors
If a noise reduction part is added between discharge ports and upper cover, then noise is reduced, but device complexity increases
Solution Approach 1:
The noise reduction part is applied locally at the discharge port area where noise is generated, rather than throughout the entire device. The noise-absorbing member is positioned specifically between the discharge ports and the upper cover, providing targeted noise reduction while minimizing the overall addition to device complexity
Solution Approach 2:
The noise-absorbing member can be implemented using cost-effective porous materials that are simple to manufacture and replace if needed. This approach allows for effective noise reduction without significant investment in complex, expensive noise control systems

AI summary
A cyclone dust collector includes a cyclone body including a first cyclone chamber to centrifugally separate dust from drawn-in air for a first time, a plurality of second cyclone chambers to centrifugally separate dust from the drawn-in air for a second time, and a plurality of discharge ports to cause the drawn-in air to be discharged from the plurality of second cyclone chambers; an upper cover to cover an upper portion of the cyclone body, the upper cover having an inner wall facing the plurality of discharge ports; and a noise reduction part disposed between the plurality of discharge ports and the inner wall of the upper cover, to reduce noise generated inside the upper cover by the air discharged through the plurality of discharge ports. Therefore, it is possible to reduce noise generated inside the upper cover of the cyclone dust collector.
