On the one hand, a large number of different types of reactive free radicals and molecular oxidants, such as hydroxide, hydrogen, oxygen, superoxide, hydrogen peroxide and ozone, are present in low-temperature plasmas. The active free radicals and the molecular oxidants of different types can be combined and reacted with the substances on the surface of the microbial cell membrane to generate chemical reaction, and the sterilization effect is achieved by killing the internal space of the safety box. On the other hand, the photolysis of strong ultraviolet light on the surface of the plasma and the supercritical oxidation of air cavitation by the plasma generate the combined action of light, electricity, chemistry and the like, thereby playing the role of physical and chemical disinfection and sterilization. When the safe is used, firstly, the door of the safe body 110 is opened through the face recognition unit 110, when the face information of the specific person extracted by the face recognition unit 110 corresponds to the face information stored in the storage unit 320, the face recognition unit 110 sends a door opening instruction to the unlocking unit 120, the door of the safe body 110 is opened, the stored article is placed in the safe body 100, and the door of the safe body 110 is closed. At this time, the safe 100 starts to perform a sterilization operation, first, gas is input into the discharge region in the array electrode unit 220 through the gas storage unit 250, the array electrode unit 220 ionizes the input gas, so that the ionized gas has a plurality of sterilization active substances, and the ionized gas is circularly sent into the safe 100 through the wind circulation unit 210, so as to sterilize and disinfect the articles stored in the safe 100. In the process, the face information or the iris information of a specific person is firstly acquired in advance and stored in the storage unit 320, so that the door is opened without contact, and cross infection is avoided. Secondly, through the mode of putting articles into the safety box firstly, closing the door of the safety box and then sterilizing the safety box and the articles to be kept, compared with the mode of putting the articles into the safety box reversely after sterilizing the inside of the safety box, the mode of putting the articles into the safety box in a one-time mode is realized, and the cross infection of secondary putting of the articles is avoided. Furthermore, the time for sterilizing the plasma unit 200 can be set by the timing unit 310, for example, the time for sterilizing the plasma unit 200 is set to be 3-10 minutes, specifically, 3 minutes, when the time reaches 3 minutes, the gas storage unit 250 does not supply gas into the plasma unit 200 any more, and the power supply unit 230 does not supply power to the array electrode unit 220 and the wind circulation unit 210 any more, so that a sterilizing process is completed.
