[0002] Airtight doors are widely used in the medical industry and the electronic manufacturing industry, such as in medical diagnostic X-ray radiography rooms, sterile wards, dust-free workshops, etc. The purpose of using airtight doors is to form an isolation barrier to isolate harmful factors such as harmful rays, pathogens, and dust. The utility model patent with the authorization announcement number CN209990390U discloses a medical airtight door with good airtightness. The technical solution provided by the patent is: the electromagnetic force formed after the electromagnet is energized drives the airtight strip to move, so as to close and open the door body. Although the electromagnetic sealing technology used in the technical solution of the patent enables the door to have better sealing performance, the door body cannot work when the power is off. In addition, the utility model patent with the authorization announcement number CN218971033U also discloses a medical airtight door. Although the patent improves the sealing effect by increasing the contact area between the sealing strip and the frame, the wear and aging of the sealing strip over time will also have an adverse effect on the sealing effect.
