Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an aerosol air purification device for medical disinfection wards. Background Art

[0002] In today's rapidly developing society, the public's concern about air quality has become an increasingly prominent social issue, among which outdoor air pollution is often put in the spotlight and becomes the focus of heated discussion. However, behind this widespread attention, there is a truth that is rarely known to the public: compared with outdoor air quality, the potential impact of indoor air quality on human health is more far-reaching and complex. Considering the characteristics of human life patterns, about 80% of precious time is spent in closed indoor spaces, especially for patients in wards. The air quality of the indoor environment has become an indispensable part of measuring the quality of life and health status, and its importance is self-evident.

[0003] In the hot summer, air conditioners have become an indispensable artifact for cooling off, and patients in wards are no exception. Especially in the context of the current accelerated spread of the virus, the impact of indoor air quality on respiratory health has become increasingly significant, causing more and more people to suffer from varying degrees of respiratory discomfort. The mainstream medical disinfection ward aerosol air purification equipment on the market, although it performs well in regulating indoor temperature and humidity and ensures comfort, is relatively limited in its effectiveness in purifying the air, especially in eliminating pathogenic microorganisms suspended in the air. Most of these devices focus on physical adjustments, lack efficient air purification and disinfection mechanisms, and are difficult to effectively resist harmful particles such as viruses and bacteria that may be carried in the air, which to a certain extent exacerbates the potential threat to health posed by indoor air quality.
