[0006] The whole porous box is made of a foaming material. The outer layer of the porous box body is made of a closed - cell porous material, and the inner layer of the porous box body is made of an open - cell porous material.

[0007] Further, a solenoid valve I, a solenoid valve II, an air pump and an air storage tank are installed in the base; the solenoid valve I and the solenoid valve II control the on - off of the gas path. The solenoid valve I controls the on - off of the gas path between the air pump and the air storage tank, and the solenoid valve II controls the on - off of the gas path between the air storage tank and the needle - type inflation nozzle; a rubber air nozzle is provided at the bottom of the outer layer of the porous box body, and after the needle - type inflation nozzle is connected to the rubber air nozzle, sterilized and bactericidal gases can be filled into the interlayer of the porous box.

[0008] Further, a sterilization device is provided inside the base. The sterilization device can sterilize the air, store the generated sterilization and disinfection gases. The sterilization device includes: an outer fine filter screen, an inner fine filter screen, an ultraviolet sterilization lamp tube, an ozone generation device, and an oxygen negative ion generation device; a baffle is provided inside the base, and the baffle divides the space inside the base into a first space and a second space; the outer fine filter screen, the ultraviolet sterilization lamp tube, the ozone generation device, and the oxygen negative ion generation device are installed in the first space, and the solenoid valve I, the solenoid valve II, the air pump, and the gas storage tank are installed in the second space; the air pump is connected to the gas storage tank through a pipeline; the gas storage tank is connected to the needle-type inflation nozzle through a pipeline; a socket is provided at the back position of the base, and an external power supply can be connected to supply power to the device.

[0010] The rubber air nozzle is placed inside the foam hole box. After the foam hole box is filled with sterilization and disinfection gases, the rubber air nozzle is flush with the bottom surface of the foam hole box to maintain stability.

[0011] The second upper cover is connected to the foam hole box through a magnetic sealing strip, and a handle is provided on the second upper cover.

[0012] A method for using a self-cleaning device with foam hole material includes the following steps of use:

[0013] Step 1: Determine the required sterilization and disinfection gases according to the category of the items placed in the foam hole box.

[0014] Step 2: After the sterilization and disinfection gases are determined, check whether the gases in the gas storage tank correspond. If they correspond, then check whether the gases in the tank are sufficient. If they are sufficient, place the foam hole box into the inner chamber of the inflation box, connect the rubber air nozzle to the needle-type inflation nozzle on the inflation box, and turn on the solenoid valve II control switch to make the gas path between the gas storage tank and the needle-type inflation nozzle unblocked, and fill the interlayer of the foam hole box with the sterilization and disinfection gases; if they are not sufficient, the corresponding sterilization and disinfection gases need to be filled into the gas storage tank; if they do not correspond, also turn on the solenoid valve II control switch to make the gas path between the gas storage tank and the needle-type inflation nozzle unblocked, and then discharge the remaining gases in the gas storage tank.

[0015] Step 3: After the remaining gases in the gas storage tank are discharged, the corresponding sterilization and disinfection gases need to be filled into the gas storage tank. First, turn on the corresponding ultraviolet generator control switch, ozone generator control switch, and oxygen negative ion generator control switch. After turning on the control switches, the air pump starts to work and the solenoid valve I is opened to make the gas path between the air pump and the gas storage tank unblocked.

[0016] Step 4: The air first passes through the outer fine filter to initially filter out impurities in the air, and then passes through the sterilization area to sterilize and disinfect the gas. After the sterilized and disinfected gas enters the inner fine filter, it is pressurized into the gas storage tank through the pipeline by the air pump. When the air pressure in the gas storage tank reaches the set threshold, the air pump and the solenoid valve I stop working, and the air path between the air pump and the gas storage tank is disconnected;

[0017] Step 5: Take out the cellular box and open the folded cellular box completely. The cellular box is made of foam material as a whole. The outer layer is a closed-cell cellular material, and the gas does not overflow, which plays the role of sealing, heat preservation and shock absorption. The inner layer is an open-cell cellular material, and the gas in the interlayer can be slowly released through the pores connected by the material. Connect the rubber gas nozzle on the cellular box with the needle-type inflation nozzle on the partition. After checking that everything is correct, open the solenoid valve II control switch to connect the gas path between the gas storage tank and the needle-type inflation nozzle, and fill the sterilization and bactericidal gas into the interlayer of the cellular box. After the inflation is completed, take out the cellular box, put the items in, and connect the cellular box to the second upper cover with a magnetic sealing strip, which can provide a sterile and antibacterial environment for the items in the cellular box.

[0042] As shown in the attached instructions Figure 13 shown Figure 13 is the logic diagram of the inflation principle of the inflation box of the present invention. Those skilled in the art can understand the usage steps of the present invention from the logic diagram.

[0043] The opening process of the foam box 4 in the folded state is as follows:

[0044] First step, take out a new foam box 4, take the surface where the rubber air nozzle 25 is located as the bottom surface of the foam box 4, and the other surface opposite to it as the front surface; for the two sides of the foam box 4, the longer side is the long side and the shorter side is the short side. With the bottom surface of the foam box 4 facing up and the long side of the foam box 4 as the horizontal side, open the folded foam box 4 outward along the short side direction, open it twice in total, and open it in opposite directions;

[0045] Second step, with the bottom surface of the foam box 4 facing up and the short side as the horizontal side, open the foam box 4 outward along the short side direction, open it twice in total, and open it in opposite directions, and then turn over the foam box 4, that is, the bottom surface is down and the front surface is up;

[0046] Third step, connect the rubber air nozzle 25 and the needle-type inflation nozzle 16, and fill the interlayer of the foam box 4 with sterilizing and bactericidal gas. As the sterilizing and bactericidal gas is continuously filled, the foam box 4 expands and becomes larger. As shown in the attached instructions Figure 11 the arrow direction of step III in the attached instructions indicates the direction of the expansion and enlargement of the foam box 4; the step IV in the attached instructions Figure 11 is the final state when the foam box 4 is filled with sterilizing and bactericidal gas.

[0047] In an embodiment of the present invention, the foaming material may be any one or a mixture of polyethylene, polypropylene, cross-linked polyvinyl chloride, polyurethane, polylactic acid, etc. In an embodiment of the present invention, a magnetic sealing strip 26 is used to connect between the first upper cover 1 and the inflatable box 2, and between the second upper cover 3 and the foam cell box 4. Other connection methods can also be used, such as snap fasteners; in this embodiment, the inflation port of the foam cell box 4 is located at the bottom, and the inflation port can also be located at other parts, such as the side of the foam cell box 4; in this embodiment, there is only one gas storage tank 13, and multiple gas storage tanks 13 can also be designed according to actual needs, such as three; in this embodiment, a needle-type inflation nozzle 16 and a rubber air nozzle 25 are used to introduce gas, and other methods can also be used, such as quick-connect valves.

[0048] In an embodiment of the present invention, the foam cell box 4 is made of a foaming material. Through the sterilizing and bactericidal gases in the slow-release interlayer of the open-cell structure, a long-term sterile and antibacterial environment is provided for the foam cell box 4. Moreover, the foaming material is light in weight and convenient to carry, has good elasticity and shock absorption effect, and also has a heat preservation function, such as being able to keep food warm, for long-distance transportation, and at the same time delay the spoilage time of the food in the box; it can also play a role in sterilizing, antibacterial, and disinfecting the items placed in the box. When the present invention is working, when the air pressure in the gas storage tank 13 < 1.3 times the standard atmospheric pressure, the display screen 20 will emit red light to remind the user. After the user turns on the control switches 22 of the ultraviolet generator, 23 of the ozone generator, and 24 of the negative oxygen ion generator, the air pump 11 and the solenoid valve I 14 start to work. The air path between the air pump 11 and the gas storage tank 13 is connected, and sterilizing and bactericidal gases are sent into the gas storage 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 storage tank 13 ≥ 1.3 times the standard atmospheric pressure, the control switch 19 of the solenoid valve II is turned on, and after connecting the needle-type inflation nozzle 16 and the rubber air nozzle 25, sterilizing and bactericidal gases start to be filled into the foam cell box 4 at a fixed flow rate for a fixed duration of 1 minute; after 1 minute, the control switch 19 of the solenoid valve II is closed, and then the air path between the gas storage tank 13 and the needle-type inflation nozzle 16 is disconnected.

[0049] The usage method of a self-cleaning device with a foam material of the present invention is as follows:

[0050] 1. Determine the required sterilizing and bactericidal gases according to the categories of the items placed in the foam cell box 4;

[0051] 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;

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;

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.
