Embodiment 1

[0044] The air valve is composed of a valve body, an air valve cover, an air plug, and a filter screen. The air valve has good one-way sealing performance, and one-way exhaust is easy. In order to achieve the one-way pumping function of the air valve, the air valve is designed as a device in which an air plug made of softer plastic material is matched with a smoother annular lip structure. The air plug has good elasticity, It is assembled with the air valve through a certain pre-tightening force, and cooperates with the smooth annular protruding lip structure of the air valve to achieve a sealing effect. And the air valve has a threaded structure, which can be assembled with a threaded air valve cover. After the threaded air valve cover is tightened, the air plug is subjected to a certain pressure, so that the air plug and the air valve maintain a tight fit to achieve good sealing performance.

[0045] The threaded structure on the air valve can also be well connected with th...

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...
