Document Type and Number:
WIPO Patent Application WO/2021/256475
Kind Code:
A1
Abstract:
[Problem] To prevent droplets dispersed in the air from directly reaching a person one is talking to, and to suck and catch to purify and sterilize the droplets dispersed in the air before the droplets drift away with the airflow, with a simple configuration. [Solution] An air purification device which comprises: a partitioning part that forms an air passage between a plurality of shielding parts disposed spaced at predetermined intervals; an air inflow part formed on the partitioning part; an air suction part that sucks air from the air inflow part via the air passage; an air purifying part that purifies the air sucked by the air suction part, or sterilizes or inactivates bacteria and viruses in the air sucked by the air suction part; and an air discharge part that discharges the air from the air purifying part. An air suction device which comprises: a partitioning part that forms an air passage between a plurality of shielding parts disposed substantially parallel to one another and spaced at predetermined intervals; an air inflow part formed on the partitioning part; and an air suction part that sucks air from the air inflow part via the air passage.
