Detailed Embodiments

[0017] The following will further illustrate the present utility model in combination with specific embodiments. It should also be noted that unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and coupling should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] Such as Figure 1-2The purification device for the inner packaging material of space fruits shown in the figure includes a box body 1. In this embodiment, the box body is preferably in the shape of a cuboid, with an open front side, and a box door 2 is installed at the open port. The internal space of the box body 1 is divided into two areas by a vertical partition: a first area and a second area. There are ventilation holes on the vertical partition 3 to connect the two areas. In the first area, a high-efficiency filter 7, a bag filter 6, an activated carbon filter 5, and a material placement plate 4 are arranged in sequence along the direction away from the vertical partition 3. As Figure 3 shown, the material placement plate 4 includes two straight plates 41 arranged horizontally and a hollow-shaped bar 42 connected to the common side of the two straight plates 41. The bar 42 is close to the activated carbon filter 5. A vacuum pump 9 is arranged in the second area. The vacuum pump 9 is preferably an oil-free pump. The purpose of using an oil-free pump is to avoid oil smell from contaminating the object to be treated. The suction end of the vacuum pump 9 is connected to the ventilation hole, and the discharge end of the vacuum pump 9 penetrates the side wall of the second area and communicates with the outside.

[0019] It should be noted that the box door 2 includes a first box door 2a and a second box door 2b. The first box door 2a is fixedly connected to the box body 1 by means of rivets or screws, etc. It covers the entire second area and part of the first area. The second box door 2b is slidably connected to the box body 1 by means of a slide rail. The second box door 2b is used to cover the other part of the first area, that is, the area not covered by the first box door 2a. After the second box door 2b is closed, the first area of the box body is close to a closed state. When in use, open the second box door 2b, place the inner lining plate on the material placement plate 4, then close the second box door 2b, and start the vacuum pump 9. The vacuum pump 9 extracts the mixed gas containing harmful gases in the first area. When the harmful gases pass through the activated carbon filter 5, the bag filter 6, and the high-efficiency filter 7, the harmful substances can be adsorbed, filtered, and removed in time (the harmful substances are mostly butane, isobutane, etc.). This device not only improves the removal efficiency of harmful gases, but also the discharged gas is purified and will not pollute the environment.

[0020] It should also be noted that an installation plate 10 is installed in the box body 1. The installation plate 10 is similar to a slide rail structure and is fixedly arranged at the top and / or bottom inside the box body 1. The activated carbon filter 5, the bag filter 6, and the high-efficiency filter 7 are embedded on the installation plate 10 in a pull-out form. When replacement or installation and disassembly are required, remove the first box door 2a and pull it out from the installation plate 10.

[0021] In addition, to further improve the removal effect of harmful gases, an ultraviolet lamp 8 can also be arranged between the activated carbon filter 5 and the bag filter 6. The ultraviolet lamp 8 can further oxidize the harmful substances to produce pollution-free substances.

[0022] In actual use, the inner lining plate is mostly made of polyethylene foam pearl cotton. During the air extraction process, due to the negative pressure, it will deform. To prevent damage, an air inlet pipe is opened on the second box door 2b2, and a solenoid valve 2b1 is set at the air inlet pipe. The solenoid valve 2b1 opens and closes intermittently, and ventilation operations are carried out during the air extraction process, which can protect the integrity of the inner lining plate and avoid causing permanent damage to it.

[0023] This device can efficiently remove harmful gases in the inner lining plate in a short time, ensuring the safety and reliability of space food packaging. Through the design and implementation of the present utility model, the processing efficiency of space food packaging can be significantly improved, the health risks of astronauts can be reduced, and a more solid material guarantee can be provided for space exploration activities.
