Oblique Cyclone Tube Layout for Space-Efficient Dust Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collecting devices for electric tools, such as grinding devices, are inefficient in utilizing space and require frequent dust dumping due to the axial alignment of the dust separating part, leading to reduced user experience and ineffective dust collection.
Innovation Solution
A cyclone dust collecting device with a cyclone tube obliquely disposed within the dust collecting box, where the dust inlet is higher than the dust outlet, allowing for increased dust accumulation space without increasing the device's volume, and an air outlet positioned away from the host machine to prevent dust re-deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the dust separating part is disposed along the axial direction of the dust inlet, then the structure is simple, but the space utilization is poor and dust accumulation space is limited
Solution Approach 1:
The cyclone tube is disposed obliquely relative to the axial direction of the dust inlet, changing the separation direction from axial to oblique. This dimensional change allows the dust separating part to utilize the radial and vertical spaces within the dust collecting box more effectively, significantly increasing the dust accumulation space without increasing the overall device volume.
2Volume of moving object
If the dust collecting box volume is increased to accommodate more dust, then the dust accumulation space is increased, but the device volume and portability are reduced
Solution Approach 1:
By disposing the cyclone tube obliquely rather than axially, the patent creates more efficient use of three-dimensional space within the dust collecting box. The oblique arrangement allows dust to accumulate in the lower portion of the box while the upper portion remains available for other components, effectively increasing dust accumulation capacity without increasing the external dimensions of the device.
Solution Approach 2:
The patent changes the orientation parameter of the cyclone tube from axial to oblique, which fundamentally alters the spatial distribution of dust accumulation. This parameter change enables the system to achieve greater dust accumulation volume within the same device envelope by optimizing the internal spatial arrangement.
3Productivity
If the dust separating part is positioned to maximize dust collection, then dust collection efficiency is improved, but the air outlet may blow dust back into the device
Solution Approach 1:
The air outlet is positioned asymmetrically relative to the cyclone tube and dust accumulation area. The air outlet is disposed at a location and orientation that directs the exhaust airflow away from the dust accumulation zone and away from the host machine body, preventing dust re-deposition while maintaining effective dust collection through the oblique cyclone configuration.
