[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] The present utility model provides a preserved halogen food packaging bag as Figures 1-5 shown, including: a fresh-keeping bag 1, a sealing strip 2 is installed at the top of the fresh-keeping bag 1, and through the engagement of the sealing strip 2, it is convenient to seal the opening of the fresh-keeping bag 1; storage bags 3 are connected to both the front and back of the fresh-keeping bag 1, and by the expansion of the storage bags 3, the inner cavity of the fresh-keeping bag 1 is squeezed, and the air in the inner cavity of the fresh-keeping bag 1 is discharged. One side of the storage bag 3 is connected to a sealing component 4, and a one-way exhaust device 5 is installed at the top of the fresh-keeping bag 1. The one-way exhaust device 5 is located above the storage bag 3. Through the one-way exhaust device 5, the air inside the fresh-keeping bag 1 can be discharged. Air or ice water is blown into the storage bag 3 through the sealing component 4, so that the storage bag 3 can expand. By the expansion of the two storage bags 3, the fresh-keeping bag 1 between them is simultaneously squeezed and pressed, and the excess air inside the fresh-keeping bag 1 is discharged through the one-way exhaust device 5, so as to discharge a large amount of air inside the fresh-keeping bag 1.

[0037] Specifically, the sealing assembly 4 includes: a connecting pipe 41, one end of the connecting pipe 41 is connected to and communicated with the storage bag 3; a sealing cover 42, the sealing cover 42 is threadedly sleeved on the outside of the connecting pipe 41. Through the connecting pipe 41, it is convenient to inject air or ice water into the interior of the storage bag 3. By filling ice water into the interior of the storage bag 3, the ice water is convenient for squeezing the fresh-keeping bag 1. While discharging the air inside the fresh-keeping bag 1, the halogen products can also be preserved through low temperature. The sealing cover 42 is convenient for sealing the inner cavity of the connecting pipe 41.

[0038] Further, the one-way exhaust device 5 includes: an exhaust pipe 51, one end of the exhaust pipe 51 is connected to and communicated with the fresh-keeping bag 1; a sliding plug 52, the sliding plug 52 is slidably arranged inside the exhaust pipe 51; an elastic support mechanism 53, the elastic support mechanism 53 is movably embedded inside the exhaust pipe 51, and the elastic support mechanism 53 is used for elastically supporting the sliding plug 52; a blocking mechanism 54, the blocking mechanism 54 is located on one side of the sliding plug 52, and the blocking mechanism 54 is used for limiting the sliding plug 52. An air release ring groove is formed inside the other end of the exhaust pipe 51, and the inner diameter of the air release ring groove is larger than the inner diameter of the sliding plug 52. When there is gas discharged from the inner cavity of the fresh-keeping bag 1, the air pressure will squeeze the sliding plug 52, so that the sliding plug 52 moves axially inside the exhaust pipe 51. While driving the elastic support mechanism 53 to move, through the movement of the sliding plug 52, the head of the air release hole 521 slides into the inside of the air release ring groove. At this time, the inner wall of the exhaust pipe 51 no longer blocks the inner cavity of the air release hole 521, so that the gas inside the exhaust pipe 51 is discharged through the air release hole 521 and the air release ring groove, so as to realize the one-way discharge of the inner cavity of the fresh-keeping bag 1. An air release hole 521 is formed inside the sliding plug 52, and the air release hole 521 is in a T shape. In the normal state, the inner wall of the exhaust pipe 51 will block the head of the air release hole 521 to prevent the entry of external air. The elastic support mechanism 53 includes: a guide rod 531, a cavity is formed inside the exhaust pipe 51, and the guide rod 531 is fixedly installed inside the cavity; a slider 532, the slider 532 is slidably inserted and connected with the guide rod 531; a spring 533, the spring 533 is movably sleeved outside the guide rod 531, and the spring 533 is used for elastically supporting the slider 532. The cavity facilitates providing a moving space for the movement of the slider 532. While the guide rod 531 facilitates limiting the spring 533, it also facilitates limiting the movement of the slider 532. Through the compression deformation of the spring 533, it is convenient to elastically support the slider 532, so that in the normal state, the sliding plug 52 is in a sealed state inside the exhaust pipe 51, and the sliding plug 52 blocks the inner cavity of the exhaust pipe 51.The blocking mechanism 54 includes: a connecting disk 541 disposed outside the exhaust pipe 51; a blocking post 542, one end of the blocking post 542 being connected to one side of the connecting disk 541; a threaded ring 543 threadedly connected to the outside of the exhaust pipe 51; a plurality of support rods 544 connected between the connecting disk 541 and the threaded ring 543. Through the blocking post 542, it is convenient to resist the sliding plug 52, preventing the sliding plug 52 from sliding randomly inside the exhaust pipe 51, thus achieving the blocking of the inner cavity of the exhaust pipe 51. By the threaded rotation of the threaded ring 543 outside the exhaust pipe 51, it is convenient to adjust the relative position between the connecting disk 541 and the exhaust pipe 51, so that the blocking post 542 no longer blocks the sliding plug 52. The support rods 544 facilitate the connection between the connecting disk 541 and the threaded ring 543.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
