Technical Field

[0001] The utility model relates to the technical field of air disinfection and purification, in particular to an air disinfection and purification device for a central air conditioner used in a hospital. Background Art

[0002] Hospitals are crowded with patients, and their environments are most susceptible to contamination by pathogenic microorganisms, creating external conditions for the spread of disease and promoting the occurrence of nosocomial infections. Hospital-acquired infections pose serious risks to both society and individuals, necessitating comprehensive measures to ensure that disinfection, sterilization, and isolation procedures meet predetermined requirements to prevent and control the occurrence of nosocomial infections. Currently, hospitals often use central air conditioning for ventilation and temperature regulation. Due to the circulating air flow, disinfection and purification devices are often installed on the intake side of central air conditioning systems in hospitals to ensure air safety and effectively purify airborne bacteria and viruses.

[0003] In order to purify the bacteria and dust in the air, a corresponding filter element structure needs to be provided inside the purification device. The existing filter element structure is mostly integrated, and the integrated filter element is fixedly installed inside the box seat structure by bolts. Not only is the disassembly and assembly convenience poor, but also due to the different replacement cycles of the filter elements, the integrated disassembly and replacement will lead to waste of the filter element. In addition, most existing purification devices are only provided with a filter element filtering treatment structure. Although it can filter and remove bacteria and viruses in the air, the bacteria and viruses are still active, which will not only contaminate the filter element but also some active bacteria and viruses will remain in the filtered air, resulting in poor purification effect. Therefore, a central air-conditioning air disinfection and purification device for hospitals is proposed. Utility Model Content
