[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 3 , the utility model provides an embodiment: a moisture-proof and moisture-preserving device for packaging and storage, comprising a box body 1, a box cover 3 is arranged on the top of the box body 1, a fan 4 is fixedly connected to the bottom end of the box cover 3, a cavity 5 is opened on the inner side of the box body 1, a return frame 6 is arranged on the inner top of the cavity 5, a moisturizing cotton 7 is fixedly connected to the bottom of the return frame 6, a plurality of ventilation holes 8 are evenly arranged around the inside of the box body 1, the size of the return frame 6 matches the size of the inner size of the cavity 5, a placement plate 9 is fixedly connected to the middle and lower part of the inner side of the box body 1, bolts 10 are threadedly connected to the left and right sides of the box body 1, one end of the bolt 10 passes through the box body 1 and the return frame 6 in sequence, and an adjustment mechanism 2 is arranged at the bottom of the placement plate 9;

[0031] Specifically, the operation of the fan 4 can accelerate the gas circulation in the box 1, which not only promotes the circulation of air, but also lays the foundation for the subsequent wetting process. As the gas flows, it will pass through the ventilation hole 8 into a specific cavity 5, in which the moisture generated by the moisturizing cotton 7 can be fully dissipated. The moisture will then pass through the space inside the box 1 to evenly moisten the objects around, ensuring that these items will not be affected by dryness or excessive moisture during storage, and loosening the bolts 10 can release the limit fixation of the return frame 6, so that the return frame 6 can be easily taken out, which provides convenience for the replacement of the moisturizing cotton 7. This design not only improves the practicality of the system, but also saves users a lot of time and energy.

[0032] Reference Figure 1 , Figure 3 and Figure 4The adjusting mechanism 2 includes a placing box 201, which is arranged at the middle and lower part of the front side of the box body 1. The rear side of the placing box 201 penetrates the box body 1. A desiccant 202 is arranged inside the placing box 201. A supporting plate 204 is fixedly connected to the bottom of the placing plate 9. A groove 205 is opened in the middle of the supporting plate 204. A cross fixing plate 206 is fixedly connected inside the groove 205. A rotating rod 207 is rotatably connected to the bottom end of the cross fixing plate 206. The outer sides of the rotating rod 207 are fixedly connected with fan-shaped plates 208. The rotating rod 207 is fixedly connected to the outer sides of the fan-shaped plates 208. A driven bevel gear 209 is fixedly connected to the middle of the outer side, and a movable rod 210 is rotatably connected to the middle and lower part of the front side of the box body 1. The rear end of the movable rod 210 passes through the box body 1 and is fixedly connected to the active bevel gear 211. The active bevel gear 211 is meshed and connected with the driven bevel gear 209. The adjustment mechanism 2 also includes a card slot 212, which is opened on the front side of the placement box 201. The placement box 201 is slidably connected to the inner bottom of the box body 1. The size of the gap on the cross fixing plate 206 matches the size of the corresponding fan-shaped plate 208.

[0033] Specifically, when drying is required, the movable rod 210 is rotated. This simple action will drive the active bevel gear 211 to start rotating. Since the driven bevel gear 209 is closely meshed with the active bevel gear 211, it will also rotate accordingly. This series of actions further promotes the rotation of the fan plate 208 until the support plate 204 is fully opened. At this time, the excess moisture in the box 1 can be blown to the placement box 201 through the fan 4. In this process, the desiccant 202 plays a vital role. Its strong adsorption capacity quickly adsorbs the moisture in the moisture, thereby achieving effective removal of moisture. When the external fresh air passes through the desiccant 202, it takes away the small molecules adsorbed by it, so that the desiccant 202 can continue to work effectively. These fresh and dry air are then reintroduced into the box 1, effectively maintaining the dry environment inside it, achieving the purpose of moisture-proofing. When drying is no longer required, the user only needs to turn the fan plate 208 back to its original position. Such a design cleverly avoids the desiccant 202 from being exposed to a humid environment for a long time, thereby preventing the risk of its failure due to moisture. Such a mechanism not only ensures the long-term use of the desiccant 202, but also greatly improves the practicality and reliability of the entire device.

[0034] Reference Figure 1 and Figure 2 A rotating shaft 14 is provided at the top rear side of the box cover 3, and the box cover 3 is rotatably connected to the top rear side of the box body 1 through the rotating shaft 14, and an opening groove 13 is provided at the top front side of the box cover 3;

[0035] Specifically, the box cover 3 can be opened conveniently through the opening slot 13 to take out the desired product.

[0036] Reference Figure 1A switch 11 is fixedly connected to the middle of the right side of the box body 1, and the switch 11 is electrically connected to the fan 4. A protective cover 12 is arranged on the outer side of the switch 11, and one side of the protective cover 12 is rotatably connected to the right side of the box body 1;

[0037] Specifically, the operation of the fan 4 can be controlled by the switch 11, and the protective cover 12 can protect the switch 11 from being damaged by external factors.

[0038] Reference Figure 3 The adjustment mechanism 2 further includes holes 203, and a plurality of holes 203 are respectively and equidistantly arranged at the bottom of the box body 1;

[0039] Specifically, the holes 203 can facilitate external air to enter the box body 1, thereby keeping the interior of the box body 1 dry.

[0040] Working principle: when the box 1 is needed to transport and store items, first open the box cover 3 and then put the items to be stored on the placement plate 9, and then close the box cover 3. At this time, the fan 4 can accelerate the gas circulation in the box 1, and the gas will enter the cavity 5 through the ventilation hole 8, and the moisture generated by the moisturizing cotton 7 in the cavity 5 will be dissipated into the box 1, so that the objects in the box 1 can be evenly moisturized all around, thereby improving the moisturizing effect, ensuring the quality of the product, and meeting the needs of users. Loosening the bolts 10 can release the limit fixation of the return frame 6. At this time, the return frame 6 can be taken out and the moisturizing cotton 7 can be replaced to ensure the humidity inside the box 1 and When drying is required, rotating the movable rod 210 can drive the active bevel gear 211 to rotate, and the driven bevel gear 209 will also rotate accordingly due to the meshing with the active bevel gear 211, thereby driving the fan plate 208 to rotate until the support plate 204 is fully opened. At this time, the fan 4 can blow the excess moisture in the box 1 to the placement box 201 to be adsorbed by the desiccant 202, and the external air will drive the small molecules of the desiccant 202 back to the box 1, so that the box 1 can achieve a moisture-proof effect. When drying is not required, the fan plate 208 can be turned back to its original state, which can prevent the desiccant 202 from being damp and affecting its subsequent normal use, thereby improving the practicality of the device.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
