Cyclone Mesh Filter Geometry for Long-Hair Dust Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collecting devices, such as those with cyclonic separating units, struggle to effectively separate long hair and similar dust due to the larger airflow volume being directed towards the airflow outlet rather than the dust exhaust port, resulting in reduced dust collection efficiency.
Innovation Solution
Incorporating a mesh filter with a reticulated cylinder body and a reticulated cover between the swirling unit and the airflow outlet in the cyclonic separating unit, where the reticulated cover has a protrusion portion axially protruding towards the swirling unit and is gradually inclined towards the airflow outlet, allowing dust to be directed along a slant surface for enhanced collection and minimizing air passage resistance.

Engineering Contradiction Analysis
1Speed
If the airflow outlet volume is increased to improve airflow discharge, then the dust collection efficiency deteriorates because dust particles are discharged without being separated
Solution Approach 1:
The cyclone separator is divided into multiple dust discharge ports arranged circumferentially, with each port serving a specific angular sector. The mesh filter is also segmented into multiple sections corresponding to these ports. This segmentation allows different regions of the airflow to be directed to appropriate discharge ports, improving dust collection efficiency while maintaining airflow discharge capability.
Solution Approach 2:
The mesh filter is designed with locally varying properties: it has a protrusion portion at the center that is gradually inclined toward the airflow outlet, creating different filtration angles and characteristics in different regions. This local quality variation ensures that dust particles in different angular positions are effectively directed to the appropriate dust discharge ports, resolving the contradiction between airflow discharge and dust collection.
2Productivity
If a mesh filter is added to improve dust collection efficiency, then the device complexity increases
Solution Approach 1:
The mesh filter is integrated with the dust discharge port structure, forming a unified component assembly. The filter's protrusion portion and inclined design are combined with the port geometry, reducing the need for separate mounting structures and simplifying the overall device complexity while maintaining improved dust collection functionality.

Function Achieved in This Case
This configuration significantly increases the dust collection efficiency by ensuring long hair and other dust particles are directed to the dust exhaust port, while maintaining low air passage resistance, thereby improving overall dust collection performance.
Implementation Method 1
a cyclonic separating unit configured to swirl, by the fan, the airflow sucked into the body case through the airflow suction portion and to separate dust contained in the sucked airflow
Implementation Method 2
the airflow is swirled by the cyclonic separating unit. Thus, the dust contained in the sucked airflow is separated

AI summary
A dust collecting device includes a mesh filter 13 provided between a swirling unit 11 and an airflow outlet 10 in a cylinder 8 which constitutes a cyclonic separating unit 5. Further, the mesh filter 13 includes a reticulated cylinder body 16 having an airflow-outlet-side opening 14 connected to the airflow outlet 10 and a swirling-unit-side opening 15 directed to the swirling unit 11 and a reticulated cover 17 configured to cover the swirling-unit-side opening 15 of the reticulated cylinder body 16. The reticulated cover 17 includes a protrusion portion axially protruding toward the swirling unit 11 at the center thereof and has such a shape that the reticulated cover 17 is gradually inclined from the protrusion portion toward the airflow outlet 10 up to an outer peripheral portion thereof.
