[0002] Gauze pads are a common infusion, nursing and protective device, mainly used in the medical field and personal care. Medical gauze pads mainly have the functions of absorbing liquids, preventing infection, protecting wounds, fixing bandages and ventilation, etc., and play an important role in the process of infusion, nursing and protection. The use of gauze pads can effectively promote wound healing, reduce the risk of infection, and provide a comfortable nursing experience. Before using medical gauze pads, it is often necessary to use sterilization equipment to treat the medical gauze pads to avoid causing infection to the patient's wound; in the prior art, high pressure sterilization is mostly used for the sterilization of medical gauze pads. Steam sterilization uses heating to generate steam. As the steam pressure continues to increase, the temperature rises accordingly, placing the medical gauze pad in a high temperature and high pressure environment, which can effectively kill all microorganisms including spores. After the medical gauze pad is sterilized, because the temperature inside the sterilization equipment is high, it is necessary to lower the temperature inside the sterilization equipment to facilitate the removal of the medical gauze pad, which increases the energy consumption of the sterilization equipment. Even though some sterilization equipment can recycle steam to reduce the energy consumption of the sterilization equipment, during the storage and retrieval of the medical gauze pad, the steam comes into contact with low-temperature air more, resulting in a large waste of heat.

Under the action of the external atmospheric pressure, the elastic force of the spring 874 is overcome to make the baffle 871 move upward. The plug post 871 leaves the air inlet hole on the bottom wall of the thermal insulation inner shell 2, and the external low-temperature air enters the interior of the thermal insulation inner shell 2 through the air inlet hole 7, the air inlet hole on the bottom wall of the thermal insulation inner shell 2 and the air hole 872, so that the sterilized medical gauze pad can be easily taken out. When sterilization is performed again, the electromagnet 875 is started, and the suction force generated by the electromagnet 875 on the metal guide column 873 is used to limit the upward movement of the baffle 871, thereby blocking the external air from entering the interior of the thermal insulation inner shell 2. At the same time, the air pump 82 is started. At this time, the air outlet pipe at the rear end of the three-way pipe 83 is connected with the front end of the three-way pipe 83, so that the low-temperature air inside the thermal insulation inner shell 2 is discharged from the rear end of the three-way pipe 83 to the outside. After the low-temperature air is discharged, the solenoid valve 86 is opened to allow the high-temperature and high-pressure gas stored in the steam box 81 to enter the steam pipe 5 from the air outlet pipe 85, so that the high-temperature and high-pressure gas returns to the interior of the thermal insulation inner shell 2 to sterilize the medical gauze pad.
