If it is described as first, second, it is only used for distinguishing technical features for the purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0025] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be understood in a broad sense, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0026] Please refer to Figs. 1-3 The utility model provides a technical scheme: a one-way exhaust valve for bag, first connecting body 1 is adhered with exhaust piece 4 on first connecting body 1, and second connecting body 2 is adhered on the side of exhaust piece 4 away from first connecting body 1;

[0027] Exhaust piece 4 is located between first connecting body 1 and second connecting body 2;

[0028] Exhaust hole 5 is formed on exhaust piece 4 and first connecting body 1;

[0029] Two exhaust grooves 3 are formed on second connecting body 2;

[0030] Two arc-shaped exhaust grooves 3 are located on both sides of exhaust hole 5;

[0031] Wherein, first connecting body 1 has adhesion on both sides, and exhaust piece 4 and second connecting body 2 are adhered on one side of first connecting body 1, when the one-way exhaust valve needs to be used, it can be adhered on the bag body through the other side of first connecting body 1;

[0032] Wherein, second connecting body 2 is PE film, and first connecting body 1 can be double-sided adhesive;

[0033] Wherein, the thickness of first connecting body 1 is 0.137-0.15mm;

[0034] Wherein, the thickness of second connecting body 2 is 0.068-0.078mm;

[0035] Wherein, the thickness of exhaust piece 4 is 0.067-0.077mm;

[0036] Wherein, the length of exhaust groove 3 is 0.6cm;

[0037] When the inside of the bag needs to be exhausted, the air inside the bag flows through the exhaust hole 5, and the pressure generated at this time causes the exhaust groove 3 on the second connecting body 2 to open, so that the air in the bag can normally flow out. At this time, since the exhaust groove 3 is located outside, when the external air pressure acts on the second connecting body 2, the exhaust groove 3 is contracted and fits on the exhaust fin 4, so as to block the external air from entering, thereby realizing the one-way exhaust function of the bag. Therefore, the inside of the bag can be in a vacuum state, thereby reducing the overall volume of the bag and the occupied space, so as to facilitate the storage or transportation of the bag.

[0038] Working principle: when the inside of the bag needs to be exhausted, the air inside the bag flows through the exhaust hole 5, and the pressure generated at this time causes the exhaust groove 3 on the second connecting body 2 to open, so that the air in the bag can normally flow out. At this time, since the exhaust groove 3 is located outside, when the external air pressure acts on the second connecting body 2, the exhaust groove 3 is contracted and fits on the exhaust fin 4, so as to block the external air from entering, thereby realizing the one-way exhaust function of the bag. Therefore, the inside of the bag can be in a vacuum state, thereby reducing the overall volume of the bag and the occupied space, so as to facilitate the storage or transportation of the bag.

[0039] The above describes the embodiments of the utility model in detail in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
