The invention relates to the technical field of medical equipment, and discloses an intelligent air sterilizer for hospital operating rooms, which includes a casing, and uses the casing to support and stabilize the entire device. The combined use of lamp tubes, threaded tubes, air outlet pipes and water pipes can extend the flow length of air during air sterilization, thereby increasing the effect of air disinfection and sterilization. At the same time, it can humidify the air and increase the overall sterilization efficiency. The sterilization effect of the device, through the combined use of the air outlet pipe, the second rotating shaft, the special-shaped rod and the swing rod, can intermittently change the direction of the sterilized air ejection, thereby increasing the fluidity of the air and avoiding the airtightness of the operating room. Uncomfortable, through the cooperative use of the special-shaped disk, the sleeve rod and the third rotating shaft, the two steps of air compression and swing rod movement are linked, which increases the linkage of the entire device and makes the operation easier.
