Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation equipment, and specifically relates to a new air duct structure. Background Art

[0002] The environmental quality of the operating room is crucial to the success of the operation and the patient's recovery. The ventilation system of the operating room plays a key role. It not only provides fresh air, but also ensures that bacteria and pollutants in the air are effectively removed to maintain a sterile and clean surgical environment.

[0003] At present, in the ventilation system of the operating room, the fresh air duct is an important component, and usually adopts multi-layer filtering and sterilization technology. The internal filter can filter out dust, particulate matter and some bacteria in the air to a certain extent. At the same time, some fresh air ducts are also equipped with sterilization lamps to sterilize the air by ultraviolet sterilization and other methods.

[0004] However, since the fresh air outlet is outside the building, the maintenance and replacement of the internal filter is a difficult problem. If it is not replaced in time, the filter element will gradually accumulate dust and impurities after long-term use, resulting in a decrease in the filtering effect. In addition, the sterilization lamp in the prior art is usually set in the air duct, so the air stays for a short time, resulting in a short irradiation time of the sterilization lamp, which cannot achieve a good sterilization effect. Utility Model Content
