Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional two-stage dust-air separation structure is used, then dust separation function is achieved, but the structure becomes complex with many parts and components
Solution Approach 1:
The patent combines the first-stage cyclone barrel and second-stage cyclone barrel into a single integrated structure where the second-stage cyclone is positioned inside the first-stage cyclone. This merging reduces the number of separate components while maintaining the two-stage dust separation function, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The patent implements a nested configuration where the second-stage cyclone barrel is nested within the first-stage cyclone barrel. This nesting arrangement allows both stages to coexist in a compact space with reduced component count, achieving effective dust separation while simplifying the overall structure.
2Reliability
If a conventional two-stage separation structure is used, then dust separation is achieved, but assembly process becomes complicated
Solution Approach 1:
By merging the two-stage cyclone structures into an integrated assembly, the patent reduces the number of assembly steps and connections required. The combined structure eliminates the need for separate mounting of independent cyclone barrels, thereby simplifying the assembly process while maintaining dust separation effectiveness.
3Volume of stationary object
If second-stage dust barrel is arranged in first-stage dust barrel, then space utilization is improved, but dust storage space is limited
Solution Approach 1:
The nested arrangement of the second-stage cyclone within the first-stage cyclone optimizes space utilization by utilizing the internal volume of the first-stage structure. This configuration maximizes the dust storage capacity within the available machine body volume while maintaining effective two-stage separation functionality.
4Reliability
If conventional machine body structure is used, then dust separation is achieved, but the shape is not suitable for handheld portable use
Solution Approach 1:
The nested cyclone structure creates a compact, space-efficient configuration that allows for a more ergonomic and portable handheld design. The integrated structure reduces the overall footprint and enables better weight distribution, making the dust collector suitable for handheld use while maintaining dust separation effectiveness.

Implementation Method 1
The first-stage cyclone barrel and the cyclone cover perform the first-stage dust-air separation on primary dusty air which enters the two-stage dust-air separation device
Implementation Method 2
Dust in the airflow, driven by a centrifugal force, rotates downward to the bottom of the second-stage cyclone barrel
Implementation Method 3
spiral two-stage tornado dust-air separation structure
Implementation Method 4
a central portion of the bottom of the second-stage cyclone barrel is designed to project downward, thereby preventing the dust from back flowing

AI summary
A handheld dust collector, a spiral two-stage tornado dust-air separation structure and a primary dust barrel are disposed in the body of the handheld dust collector. The spiral two-stage tornado dust-air separation structure includes a first-stage cyclone barrel, a second-stage cyclone barrel, a cyclone cover, and a spiral dust-air separation apparatus disposed at the upper end of the second-stage cyclone barrel. The first-stage cyclone barrel and the cyclone cover perform first-stage dust-air separation on primary dust-air entering the spiral two-stage tornado dust-air separation structure, and second-stage dust-air after previous separation enters the second-stage cyclone barrel for second-stage dust-air separation. The dust collector is small in the number of components, simple in assembling procedure, and high in comprehensive performance of a complete machine. The spiral two-stage tornado dust-air separation structure is relatively small in size, and effectively reduces the space of a machine body and achieves a maximum dust storage volume.
