[0023] As the instruction manual Fig.13 As shown, Fig.13 It is a logical diagram of the inflation principle of the inflation box of the present invention. Those skilled in the art can understand the use steps of the present invention from the logical diagram.

[0024] The opening process of the folded foam box 4 is as follows: The first step is to take out a new cellular box 4, and use the surface where the rubber air nozzle 25 is located as the bottom surface of the cellular box 4, and the other side opposite to it as the front surface; the two sides of the cellular box 4, the longer one is the long side, and the shorter one is the short side. With the bottom surface of the cellular box 4 facing upwards, and the long side of the cellular box 4 as the horizontal side, the folded cellular box 4 is opened outward along the short side direction, twice in total, and opened in opposite directions; In the second step, the cellular box 4 is opened outward along the short side with the bottom side facing upward, with the short side as the horizontal side, twice in total, and in opposite directions, and then the cellular box 4 is turned over, that is, the bottom side faces downward and the front side faces upward; The third step is to connect the rubber gas nozzle 25 and the needle-type gas-filling nozzle 16, and fill the interlayer of the bubble box 4 with sterilizing and sterilizing gas. As the sterilizing and sterilizing gas is continuously filled, the bubble box 4 expands and becomes larger. Fig.11 The direction of the arrow in step III indicates the direction in which the foam box 4 expands; Fig.11 Step IV is the final state in which the pore box 4 is filled with sterilizing and sterilizing gas.

[0025] In the embodiment of the present invention, the foaming material can be any one or more mixtures of polyethylene, polypropylene, cross-linked polyvinyl chloride, polyurethane, polylactic acid, etc. In the embodiment of the present invention, the first upper cover 1 and the gas-filling box 2, and the second upper cover 3 and the cellular box 4 are connected by a magnetic sealing strip 26, and other methods such as snaps can also be used for connection; in this embodiment, the gas-filling port of the cellular box 4 is located at the bottom, and the gas-filling port can also be located at other positions, such as the side of the cellular box 4; in this embodiment, there is only one gas storage tank 13, and multiple gas storage tanks 13, such as three, can also be designed according to actual needs; in this embodiment, a needle-type gas-filling nozzle 16 and a rubber gas nozzle 25 are used to introduce gas, and other methods such as a quick-connect valve can also be used.

[0026] In the embodiment of the present invention, the foam box 4 is made of foam material, and the sterilizing and bactericidal gases in the slow-release interlayer of the open-cell foam structure provide the foam box 4 with a sterile and antibacterial environment for a relatively long time. In addition, the foam material is light in weight and easy to carry, has good elasticity and shock absorption effect, and has a heat preservation function, such as keeping food warm and transporting it over long distances, while delaying the spoilage time of food in the box; it can also sterilize, inhibit and disinfect the items placed in the box. The design of the present invention is in operation. When the air pressure in the gas tank 13 is less than 1.3 times the standard atmospheric pressure, the display screen 20 will emit a red light to remind the user. After the user turns on the ultraviolet generator control switch 22, the ozone generator control switch 23, and the oxygen negative ion generator control switch 24, the air pump 11 and the solenoid valve I14 start to work, the air path between the air pump 11 and the gas tank 13 is connected, and sterilizing and bactericidal gas is sent into the gas tank 13. After the air pressure in the tank reaches the set threshold, no more gas is sent into the tank; when the air pressure in the gas tank 13 is ≥1.3 times the standard atmospheric pressure, the solenoid valve II control switch 19 is turned on, and after the needle-type inflation nozzle 16 and the rubber gas nozzle 25 are connected, the sterilizing and bactericidal gas is started to be filled into the bubble box 4, with a fixed flow rate and a fixed duration of 1 minute; after 1 minute, the solenoid valve II control switch 19 is closed, and then the air path between the gas tank 13 and the needle-type inflation nozzle 16 is disconnected.

[0027] The method for using a self-cleaning device with a cellular material of the present invention is as follows: 1. Determine the required sterilization and sterilization gas according to the type of items placed in the bubble box 4; 2. After the sterilization and bactericidal gases are determined, check whether the gas in the gas tank 13 corresponds. If so, check whether the gas in the tank is sufficient. If sufficient, put the pore box 4 into the inner chamber of the gas-filled box 2, connect the rubber gas nozzle 25 and the needle-type gas-filling nozzle 16 on the partition 18, and open the solenoid valve II control switch 19 to connect the gas path between the gas tank 13 and the needle-type gas-filling nozzle 16, and fill the sterilization and bactericidal gases into the interlayer of the pore box 4; if insufficient, fill the corresponding sterilization and bactericidal gases into the gas tank 13; if not corresponding, also open the solenoid valve II control switch 19 to connect the gas path between the gas tank 13 and the needle-type gas-filling nozzle 16, and then discharge the remaining gas in the gas tank 13; 3. After the gas in the gas tank 13 is discharged, the corresponding sterilizing and bactericidal gas needs to be filled into the gas tank 13. First, turn on the corresponding ultraviolet generator control switch 22, ozone generator control switch 23, and oxygen negative ion generator control switch 24. After turning on the control switch, the air pump 11 and the solenoid valve 114 start working, so that the air path between the air pump 11 and the gas tank 13 is connected; the gas first passes through the outer fine filter 6 to preliminarily filter out impurities in the air, and then passes through the sterilization area to sterilize and sterilize the gas. After the sterilizing and bactericidal gas passes through the inner fine filter 30, it is pressurized by the air pump 11 through the pipeline 12 into the gas tank 13. When the air pressure in the gas tank 13 reaches the set threshold, the air pump 11 and the solenoid valve 114 stop working, and the air path between the air pump 11 and the gas tank 13 is disconnected; 4. Take out the cellular box 4 and fully open the folded cellular box 4. The cellular box 4 is made of foam material as a whole. The outer layer of the cellular box 4 is a closed-cell cellular material 28, and the gas does not overflow, which plays the functions of sealing, heat preservation and shock absorption; the inner layer of the cellular box 4 is an open-cell cellular material 29, and the gas in the interlayer can be slowly released through the pores connected by the material; the rubber gas nozzle 25 on the cellular box 4 is connected to the needle-type inflation nozzle 16 on the partition 18. After checking, open the electromagnetic valve II control switch 19 to make the air path between the gas storage tank 13 and the needle-type inflation nozzle 16 connected, and the sterilizing and sterilizing gas is filled into the interlayer of the cellular box 4. After the inflation is completed, take out the cellular box 4, put the articles in, and connect the cellular box 4 with the second upper cover 3 with a magnetic sealing strip 26, which can provide a long-term aseptic and antibacterial environment for the articles in the cellular box 4.

The cellular box (4) is made of foam material as a whole, and the outer layer is a closed-cell cellular material (28). Gas does not overflow, and it plays the role of sealing, heat preservation and shock absorption; the inner layer is an open-cell cellular material (29), and the gas in the interlayer can be slowly released through the pores connected by the material; connect the rubber gas nozzle (25) on the cellular box (4) with the needle-type gas filling nozzle (16) on the partition (18), and after checking that it is correct, open the electromagnetic valve II control switch (19) to make the gas path between the gas storage tank (13) and the needle-type gas filling nozzle (16) connected, and fill the sterilization and bactericidal gas into the interlayer of the cellular box (4). After the inflation is completed, take out the cellular box (4), put the articles in, and connect the cellular box (4) with the second upper cover (3) with a magnetic sealing strip (26), so as to provide a sterile and antibacterial environment for the articles in the cellular box (4).
