DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1-5 As shown, the present application provides a breathable packaging bag, comprising: a packaging bag body 1 and a breathable component 3, a sealing strip 2 is installed on the packaging bag body 1, the sealing strip 2 is used to seal the bag mouth of the packaging bag body 1, the breathable component 3 is located on one side of the packaging bag body 1, the breathable component 3 comprises a fixed disk 31 and a rotating disk 32, the rotating disk 32 is rotatably connected to the fixed disk 31, the fixed disk 31 passes through the packaging bag body 1, the fixed disk 31 is fixedly connected to the packaging bag body 1, a second through hole 38 is opened inside the fixed disk 31, and a first through hole 34 is opened inside the rotating disk 32; wherein the rotating disk 32 rotates relative to the fixed disk 31 to adjust the size of the overlapping area of ​​the first through hole 34 and the second through hole 38.

[0032] In this embodiment, since the turntable 32 and the fixed disk 31 are connected for relative rotation, when the items packaged in the packaging bag body 1 need to be sealed and stored, a sealed environment can be formed by staggering the positions of the first through hole 34 and the second through hole 38. When the items packaged in the packaging bag body 1 need to be breathable, an overlapping area can be formed by overlapping the positions of the first through hole 34 and the second through hole 38. The items in the packaging bag body 1 use the overlapping area as a ventilation channel to provide appropriate ventilation. Through this design, the packaging bag body 1 can switch between sealing and ventilation as needed, providing a flexible packaging solution, which not only meets the requirements of some items that need to be sealed and stored, but also meets the requirements of other items that need to be breathable and stored. This switching mechanism can adapt to the storage needs of different items and improve the applicability and flexibility of packaging.

[0033] It is worth noting that the fixed disk 31 and the rotating disk 32 are connected by mechanical sealing.

[0034] like Figure 1-4 As shown, a pointer 36 is installed on the outer wall of the turntable 32 , and the pointer 36 can be fixed to the outer wall of the pointer 36 by bonding. The surface of the fixed disk 31 is engraved with scale lines 37 .

[0035] In this embodiment, the cooperation between the pointer 36 and the scale line 37 facilitates the user to accurately adjust the size of the overlapping area of ​​the first through hole 34 and the second through hole 38 to meet different packaging requirements.

[0036] like Figure 4 As shown, a first dustproof net 35 is installed on the inner wall of the first through hole 34 , and a second dustproof net 39 is installed on the inner wall of the second through hole 38 .

[0037] In this embodiment, the first dustproof net 35 and the second dustproof net 39 are provided to prevent dust, thereby preventing external dust from contaminating the items inside the packaging bag body 1 during the ventilation process.

[0038] like Figure 3-5 As shown, the ventilation component 3 also includes an air suction piece 33, which is installed on one side of the turntable 32. The turntable 32 is provided with a reserved hole 310. The air suction piece 33 includes an air suction cylinder 331, which can be fixed on the turntable 32 by welding. A connecting rod 332 is slidably connected inside the air suction cylinder 331, and a piston 333 adapted to the air suction cylinder 331 is installed at one end of the connecting rod 332. A pressing block 335 is installed at the end of the connecting rod 332 away from the piston 333. Both ends of the piston 333 are fixedly connected to the pressing block 335 and the piston 333 by welding. An air outlet pipe 334 connected to the air suction cylinder 331 is installed on the outer wall of the air suction cylinder 331, and the air suction cylinder 331 is connected to the reserved hole 310.

[0039] In this embodiment, when it is necessary to vacuum-package the items in the packaging bag body 1, the turntable 32 can be rotated to make the position of the vacuum member 33 correspond to the second through hole 38, and the user can hold the pressing block 335 to control the piston 333 to perform reciprocating piston motion in the vacuum cylinder 331. The gas in the packaging bag body 1 is discharged into the vacuum cylinder 331 through the reserved hole 310, and then discharged to the outside through the outlet pipe 334, thereby forming a vacuum environment in the packaging bag body 1, which can meet the packaging work of items under different storage conditions.

[0040] like Figure 5 As shown, one-way valves are installed inside the reserved hole 310 and the air outlet pipe 334 .

[0041] In this embodiment, the one-way valve is set to ensure that the piston 333 can prevent external gas from being discharged into the vacuum cylinder 331 through the outlet pipe 334 during the piston movement, and at the same time prevent the gas in the vacuum cylinder 331 from being discharged into the packaging bag body 1 through the reserved hole 310, thereby ensuring the normal operation of the vacuum operation.

[0042] like Figure 1-5 As shown, the diameter of the second through hole 38 is the same as the diameter of the first through hole 34 .

[0043] Working principle:

[0044] When the items packed in the packaging bag body 1 need to be sealed and stored, the positions of the first through hole 34 and the second through hole 38 can be staggered to form a sealed environment. When the items packed in the packaging bag body 1 need to be breathable and stored, the positions of the first through hole 34 and the second through hole 38 can be overlapped to form an overlapped area. The items in the packaging bag body 1 use the overlapped area as a breathable channel to provide appropriate ventilation. Through this design, the packaging bag body 1 can switch between sealing and ventilation as needed. When the items in the packaging bag body 1 need to be vacuum packed By rotating the turntable 32, the position of the vacuum member 33 can be made to correspond to the second through hole 38. The user can hold the pressing block 335 to control the piston 333 to perform reciprocating piston movement in the vacuum cylinder 331. The gas in the packaging bag body 1 is discharged into the vacuum cylinder 331 through the reserved hole 310, and then the gas is discharged to the outside through the outlet pipe 334, so that a vacuum environment is formed in the packaging bag body 1. After the vacuuming is completed, the turntable 32 can be rotated to close the second through hole 38, so that the packaging bag body 1 is in a sealed state, which can meet the packaging work of items under different storage conditions.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
