[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] This utility model discloses a foldable pillow packaging bag, such as Figure 1-10 As shown, the bag includes a bag body 1. The outer surface of the bag body 1 is provided with a zipper assembly. The zipper assembly includes a first chain 2 fixedly installed on the outer surface of the bag body 1. One side of the outer surface of the bag body 1 is provided with an opening. A second chain 3 is fixedly installed on the side of the outer surface of the bag body 1 near the opening, so that the user can put the pillow into the bag body 1 through the opening. A part of the first chain 2 and the second chain 3 are both located on the outer surface of the opening of the bag body 1.

[0028] The first chain 2 surrounds the entire bag body 1, while the second chain 3 surrounds the opening on the outer surface of the bag body 1. The length of the second chain 3 is less than that of the first chain 2.

[0029] The first chain belt 2 has chain teeth on one side near the second chain belt 3, and the second chain belt 3 has chain teeth on both sides. The first chain belt 2 and the second chain belt 3 have a pull head 6 on the opposite side. One side of the second chain belt 3 is arc-shaped. When the user pulls the pull head 6, the pull head 6 will move along the chain teeth of the first chain belt 2 and the chain teeth of the second chain belt 3, thereby realizing the opening and closing of the bag body 1.

[0030] When the zipper 6 moves to the end of the opening of the bag body 1, the opening of the bag body 1 will close. Then, the user folds the bag body 1 containing the pillow so that the remaining teeth of the first chain 2 are close to the teeth on the other side of the second chain 3. At this time, continue to pull the zipper 6 so that it moves along the remaining teeth of the first chain 2 and the teeth on the other side of the second chain 3. This will fix the folded bag body 1, which can reduce the space occupied by the bag body 1 when carrying it, making it easy to carry and convenient to load and unload.

[0031] A dehumidifier box 4 is fixedly installed on one side of the outer surface of the bag body 1, and the dehumidifier box 4 is filled with silica gel desiccant. When the silica gel desiccant comes into contact with moisture, water molecules in the environment enter the silica gel micropores through diffusion. Due to the size sieving effect of the micropores and the polar attraction of the silanol groups, water molecules are preferentially adsorbed on the surface of the micropores and gradually fill the gaps in the micropores to achieve the effect of adsorbing moisture.

[0032] One side of the dehumidifier box 4 extends into the interior of the bag body 1, and the dehumidifier box 4 is provided with a rotating cover 5 on the side outside the bag body 1.

[0033] The dehumidifier box 4 is rotatably connected to a rotating rod 401, and partitions 402 are fixedly installed on both sides of the rotating rod 401. When the rotating rod 401 rotates, it will drive the two partitions 402 to rotate. The dehumidifier box 4 has multiple vent holes 403 on one side inside the bag body 1. Silica gel desiccant is filled into one side of the dehumidifier box 4. When the silica gel desiccant is used to absorb the moisture in the bag body 1, the rotating rod 401 is rotated, causing the partitions 402 to rotate. The partitions 402 will then push the silica gel desiccant to move inside the dehumidifier box 4. When the silica gel desiccant moves to the side with the vent holes 403, the moisture in the bag body 1 will come into contact with the silica gel desiccant through the vent holes 403 to absorb the moisture.

[0034] When the bag 1 is not in use, the rotating rod 401 can be used again to rotate the partition 402, so that the partition 402 pushes the silica gel desiccant into the dehumidification box 4 to the side away from the vent 403.

[0035] One end of the rotating rod 401 extends to the outside of the dehumidification box 4 and is rotatably connected to the mounting plate 407. A baffle 404 is fixedly installed on one side of the outer surface of the dehumidification box 4, and two limiting holes 405 are opened on one side of the baffle 404. An movable groove 406 is opened on one side of the outer surface of the dehumidification box 4.

[0036] A connecting hole 501 is provided in the middle of one side of the rotating cover 5, and an installation hole 502 is provided inside the connecting hole 501. When assembling the rotating cover 5 with the dehumidifying box 4, the end of the rotating rod 401 extending to the outside of the dehumidifying box 4 is inserted into the connecting hole 501 until the mounting plate 407 passes through the installation hole 502. Then, the mounting plate 407 is rotated so that it does not coincide with the installation hole 502, so that the rotating cover 5 and the rotating rod 401 can be connected. Then, when the user manually rotates the rotating cover 5, it will drive the rotating rod 401 to rotate.

[0037] Multiple threaded cylinders 503 are fixedly installed on the side of the rotating cover 5. The threaded cylinders 503 are internally threaded with threaded rods 5021. One end of the threaded rod 5021 extends to the inside of the rotating cover 5 and is fixedly installed with a ball seat 505. The ball seat 505 is provided with a ball head 506 inside. The other end of the threaded rod 5021 extends to the outside of the rotating cover 5 and is fixedly installed with a handle 504. The user can hold and rotate the handle 504 to drive the threaded rod 5021 to rotate, which in turn drives the ball seat 505 and the ball head 506 to move.

[0038] After connecting the rotating cover 5 to the rotating rod 401, the rotating cover 5 will cover the opening of the dehumidification box 4. At this time, rotating the handle 504 will drive the threaded rod 5021 to rotate, pushing the ball seat 505 to move, so that the ball head 506 can roll into contact with the movable groove 406. Then, when the user rotates the rotating cover 5, multiple ball heads 506 will roll along the movable groove 406.

[0039] A movable hole 507 is provided on one side of the rotating cover 5. A spring 508 is fixedly installed inside the movable hole 507. A limit head 509 is slidably connected inside the movable hole 507, and the limit head 509 is fixedly connected to the spring 508. A lever 510 is fixedly installed on the side of the limit head 509 outside the movable hole 507. During the rotation of the rotating cover 5, the limit head 509 will squeeze the spring 508 under the obstruction of the baffle 404. When the limit head 509 rotates to the limit hole 405, the squeezed spring 508 will push the limit head 509 to reset, so that the limit head 509 is inserted into the limit hole 405, thereby limiting and fixing the rotating cover 5 and the rotating rod 401 after rotation.

[0040] The working principle of this utility model is as follows: The user puts the pillow into the bag 1 through the opening on the outer surface of the bag 1. Then the user manually pulls the zipper 6, and the zipper 6 will move along the chain teeth of the first chain belt 2 and the second chain belt 3 until the zipper 6 moves to the end of the opening of the bag 1, and the opening of the bag 1 will close. Then the user folds the bag 1 containing the pillow so that the remaining chain teeth of the first chain belt 2 are close to the chain teeth on the other side of the second chain belt 3. At this time, the user continues to pull the zipper 6, so that it moves along the remaining chain teeth of the first chain belt 2 and the chain teeth on the other side of the second chain belt 3, and the folded bag 1 can be fixed.

[0041] Fill one side of the dehumidifier box 4 with silica gel desiccant, then insert the end of the rotating rod 401 that extends to the outside of the dehumidifier box 4 into the connection hole 501 until the mounting plate 407 passes through the mounting hole 502. Then rotate the mounting plate 407 so that it does not coincide with the mounting hole 502, so that the rotating cover 5 can be connected to the rotating cover 5. When the user manually rotates the rotating cover 5, it will drive the rotating rod 401 to rotate.

[0042] After connecting the rotating cover 5 to the rotating rod 401, the rotating cover 5 will cover the opening of the dehumidification box 4. At this time, rotating the handle 504 will drive the threaded rod 5021 to rotate, pushing the ball seat 505 to move until the ball head 506 rolls into contact with the movable groove 406. Then, when the user rotates the rotating cover 5, multiple ball heads 506 will roll along the movable groove 406.

[0043] Pull the lever 510 to pull the limiting head 509 out of the current limiting hole 405, and manually rotate the rotating cover 5 to make the rotating rod 401 and the two partitions 402 rotate. The two rotating partitions 402 can push the silica gel desiccant to the side of the dehumidification box 4 with the vent 403, so that the moisture in the bag 1 can come into contact with the silica gel desiccant to absorb the moisture.
