Solution Overview

Problem

Traditional cleaners with bag filters, single-cone filters, and tornado systems suffer from poor air-dust separation efficiency and are prone to entanglement issues with garbage, leading to reduced performance and shortened service life due to the grid structure on separators.

Innovation Solution

A flat separator design featuring a circular base with airflow guiding portions that protrude or concave from the surface, eliminating the grid structure and incorporating a reinforcing structure with a ring-shaped connecting plate and shaft coupling, which reduces entanglement and enhances separation efficiency.
