DETAILED DESCRIPTION

[0026] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figure 1-Figure 7 As shown, the highly sealed storage bag provided in this embodiment comprises a main body 1, a storage cavity 2 is provided in the main body 1, a storage opening 3 is provided at one end of the storage cavity 2, and a detachable air extraction valve structure 4 is provided at the bottom of the other end of the storage cavity 2;

[0028] The detachable air extraction valve structure 4 includes a connecting sleeve 5, an internal fixed sealing air ring 6 which is screwed and fixed to one end of the connecting sleeve 5, and a sealing air valve structure 7 which is screwed and fixed to the other end of the connecting sleeve 5. The detachable air extraction valve structure 4 can divide the air extraction valve and the storage bag into two parts, and the sleeve 5 plays the role of connecting the internal fixed sealing air ring 6 and the sealing air valve structure 7.

[0029] The sealing air valve structure 7 includes an exhaust tube cavity 8, a first exhaust port 9, a hemispherical rubber ball 10, a second exhaust port 11 and a sealing cap 12. The hemispherical rubber ball 10 can block the second exhaust port 11 after exhausting the air to prevent air leakage. The sealing cap 12 further improves the sealing performance of the sealing air valve structure 7.

[0030] A limit slip ring 13 is provided on the hemispherical rubber ball 10, and a first sealing rubber pad 14 adapted to its shape is provided between the first air suction port 9 and the contact surface of the hemispherical rubber ball 10. The limit slip ring 13 enables the hemispherical rubber ball 10 to slide at a specified position to prevent shaking, and the first sealing rubber pad 14 improves the sealing effect.

[0031] The sealing cap 12 is screwed and fixed on the second air exhaust port 11. A spring top block 15 is provided at one end of the sealing cap 12, and an "I"-shaped pull buckle 16 is provided at the other end of the sealing cap 12. The spring top block 15 can apply a certain pressure to the hemispherical rubber ball 10 to make the sealing effect better. The "I"-shaped pull buckle 16 facilitates the screwing connection or screwing disassembly of the sealing cap 12.

[0032] A second sealing rubber pad 17 is arranged between the sealing cap 12 and the second air pumping port 11 , and a limiting ring 18 is arranged in the air pumping tube cavity 8 . The second sealing rubber pad 17 improves the sealing effect, and the limiting ring 18 prevents the hemispherical rubber ball 10 from blocking the second air pumping port 11 .

[0033] A "cross" lever 19 is provided on the inner fixed sealing air ring 6, and a partition net 20 is provided on the side of the "cross" lever 19 close to the first air suction port 9. The "cross" lever 19 is convenient for screwing and connecting or disassembling the inner fixed sealing air ring 6, and the partition net 20 prevents items in the storage bag from entering the air suction valve.

[0034] A hole 21 adapted to the connecting sleeve 5 is provided at the bottom of the storage cavity 2, and a third sealing rubber pad 22 is provided on both sides of the edge of the hole. The hole 21 is convenient for installing a detachable air extraction valve structure 4, and the third sealing rubber pad 22 improves the sealing effect when the detachable air extraction valve structure 4 is connected to the hole 21 at the bottom of the storage bag.

[0035] The outer surface of the main body 1 is provided with a plurality of protective anti-skid rubber strips 23, the opening of the storage port 3 is provided with a concave-convex sealing strip 24, both ends of the storage port 3 are provided with rubber hanging rings 25, and a fourth sealing rubber pad 26 is provided between the sealing air valve structure 7 and the connecting sleeve 5. The protective anti-skid rubber strip 23 is convenient for preventing slipping when multiple storage bags are stacked for storage, and can also prevent the storage bags from being damaged by direct friction with the outside world. The concave-convex sealing strip 24 can press and seal the storage port 3 after an object is placed in it, and the rubber hanging ring 25 can be hung in the closet through a hanger or a rope. The fourth sealing rubber pad 26 improves the sealing effect.

[0036] like Figure 1-Figure 7 As shown, the principle of the high-sealing storage bag provided by this embodiment is as follows: when using the utility model, the connecting sleeve 5 should be placed in the hole 21 first, and then the inner fixed sealing air ring 6 should be screwed and connected to the connecting sleeve 5 exposed inside the storage bag through the storage port 3, and then the sealing air valve structure 7 should be screwed and connected to the connecting sleeve 5 exposed outside the storage bag;

[0037] Then, put the items into the storage cavity 2 through the storage opening 3, and then seal the storage opening 3 through the concave-convex sealing strip 24, and then screw the vacuum pump into the second vacuum opening 11 to vacuum the storage belt. After the air is evacuated, put the storage bag vertically so that the hemispherical rubber ball 10 can be better embedded in the first sealing rubber pad 14, thereby blocking the first vacuum opening 9. At this time, screw the vacuum pump off, and finally screw the sealing cap 12 into the second vacuum opening 11;

[0038] If the exhaust valve is found to be damaged during use, the external sealing valve structure 7 can be screwed off from the connecting sleeve 5, and then a new sealing valve structure 7 can be screwed and connected to the connecting sleeve 5;

[0039] If the storage bag is found to be scratched due to wear during use, the internal fixed sealing air ring 6 can be screwed and removed from the connecting sleeve 5, and the external sealing air valve structure 7 can also be screwed and removed from the connecting sleeve 5, and then a new storage bag can be replaced, and finally the connecting sleeve 5 can be placed in the hole 21 at the bottom of the storage bag, the internal fixed sealing air ring 6 is screwed and connected to one end of the connecting sleeve 5 in the storage cavity 2, and the sealing air valve structure 7 is screwed and connected to the other end of the connecting sleeve 5 outside the storage bag.

[0040] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0041] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0042] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
