Food garbage disposal bag for aerospace

Abstract

The invention discloses a food garbage disposal bag for aerospace. The food garbage disposal bag for aerospace is characterized in that the disposal bag comprises (i) a bag body with a foreign object placement opening, (ii) a sealing component which comprises a bone zipper which is arranged at the foreign object placement opening, a slide sheet for pressing the bone zipper and a limiter for limiting the position of the slide sheet, and (iii) a suction component air valve on the side face of the bag body, wherein the air valve comprises a valve body, an air plug and an air valve cover; the valve body is provided with a flange structure; a cylindrical structure is arranged on the upper side of the valve body and is provided with external threads; a circular boss structure is arranged on the inner side; an annular convex lip structure is arranged at the periphery on the upper side of the boss structure; the air plug is an elastic spacer; the outer edge of the elastic spacer covers the annular convex lip structure for forming air-tight matching with the convex lip structure under the action of external pressing force; the air valve cover is provided with internal threads and is in threaded connection with the cylindrical structure for providing pressing force of the elastic spacer and the convex lip structure.

Description

technical field [0001] The invention relates to a storage bag, in particular to a food waste disposal bag for aerospace. Background technique [0002] In manned spaceflight missions, with the gradual extension of flight time, how to deal with the food waste remaining after astronauts' meals has become a problem that our country's manned spaceflight must face. Because food waste has the characteristics of high water content and rich nutrients, it provides ideal conditions for the rapid growth and reproduction of microorganisms. The growth and reproduction of microorganisms will cause food waste to spoil and deteriorate, resulting in odor and further polluting the cabin environment. How to avoid such problems, so as to ensure the safety and health of astronauts? If the food waste is sealed and vacuumized, and a deoxidizer is placed to remove most of the residual oxygen, it can greatly delay the growth and reproduction of microorganisms, slow down the deterioration of food wa...

Problems solved by technology

[0003] Aiming at the deficiencies of the existing vacuum compression bag, such as the weak connection between the air pumping device and the air valve, the inability to effectively filter the food, and the inability to effectively remove the remaining oxygen in the compression bag, the present invention provides a vacuum cleaner that can be used in aerospace A food waste storage bag in a microgravity environment. At the same time, the food waste storage bag can also be applied to the collection and temporary storage of food waste during mountaineering and travel
