AI Technical Summary
Existing dust hood designs have airflow blind spots, which makes it easy for dust to remain and results in poor cleaning performance.
The internal space of the cover is divided into two independent chambers by a ring plate, and multiple hollow grooves are opened on the ring plate. When vacuuming, the dust is evenly distributed and flows through the hollow grooves, avoiding airflow blind spots and enhancing the vacuuming effect.
It effectively reduces dust residue, improves suction and cleaning performance, ensures uniform suction in all areas of the enclosure, reduces airflow noise, and improves suction efficiency.
