Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3. In this embodiment of the present invention, a moisture-proof packaging box includes a packaging box 1 and a box lid assembly 2. The packaging box 1 includes a box body 101 and a receiving edge 102, which is integrally formed on the top of the box body 101. The box lid assembly 2 includes a box lid body 201, a connecting edge 202, a concave storage groove 204, and a through hole 205.

[0022] The sleeve edge 202 is integrally formed on the bottom periphery of the box cover body 201, the concave storage groove 204 is formed in the middle of the box cover body 201, and the through hole 205 is opened at the bottom of the concave storage groove 204.

[0023] The box cover body 201 is sleeved on the outside of the receiving edge 102 through the sleeve edge 202 to seal the opening of the receiving edge 102. The concave storage groove 204 is connected to the box body 101 and the inner cavity of the receiving edge 102 through the through hole 205. The inner side of the concave storage groove 204 is used to place desiccant, thereby achieving moisture protection for the inner cavity of the box body 101 and the receiving edge 102.

[0024] A sealing assembly 3 is provided on the top of the box cover body 201. The sealing assembly 3 is used to seal the port of the concave storage groove 204.

[0025] The sealing assembly 3 includes a sealing cap 301 and an annular retaining edge 302. The annular retaining edge 302 is integrally formed on the bottom outer side of the sealing cap 301, and the inner wall side of the concave storage groove 204 is integrally formed with a first annular protrusion 206.

[0026] The sealing cap 301 is snapped into the inner side of the first annular protrusion 206 by the annular snap edge 302 to seal the port of the concave storage groove 204;

[0027] A sealing ring 4 is fitted between the outer side of the concave storage groove 204 and the inner side of the sleeve edge 202. The inner side of the sealing ring 4 is formed with an inner groove that matches the first annular protrusion 206. The sealing ring 4 is fitted with the first annular protrusion 206, and the lower surface of the sealing ring 4 is in contact with the top of the receiving edge 102 to achieve the connection and sealing between the packaging box 1 and the box cover assembly 2.

[0028] In this embodiment, it should be noted that the sealing component 3 can be made of materials such as metal, wood, rubber, and PVC. The top of the sealing cap 301 can be engraved with a trademark pattern according to customer needs, so that the packaging box can better adapt to market demands.

[0029] When the packaging box 1 is not in use, its sealing component 3 is separated from the lid assembly 2. At this time, the desiccant is not placed in the concave storage groove 204. When the packaging box 1 is used to package the product, the desiccant is placed in the concave storage groove 204. Then, the sealing component 3 is pressed into the concave storage groove 204 by the extrusion device, so that the sealing cap 301 is distributed at the port of the concave storage groove 204. The annular locking edge 302 is engaged with the inner side of the first annular protrusion 206, thereby realizing the connection and fixation between the sealing component 3 and the lid assembly 2.

[0030] Next, place the product inside the box 101, and then close the assembled lid assembly 2 on the top of the box 101. At this time, the inner space of the concave storage groove 204 is connected to the inner cavity of the box 101 through the through hole 205. When moisture in the outside air enters the box 101, the desiccant inside the concave storage groove 204 can absorb the moisture, thereby maintaining a good dry environment inside the box 101 and achieving a moisture-proof effect.

[0031] In addition, when the lid assembly 2 is assembled with the packaging box 1, the top of the receiving edge 102 is attached to the lower surface of the sealing ring 4 to achieve a sealing effect, further preventing external moisture from entering the box body 101.

The second annular protrusion 207 is distributed below the first annular protrusion 206. A first inner folded edge 103 is formed on the top of the receiving edge 102. The first inner folded edge 103 and the second annular protrusion 207 are squeezed and snapped together to realize the connection between the packaging box 1 and the box lid assembly 2.

[0033] The bottom of the box cover body 201 is integrally formed with a second inner folded edge 203, and the inner ring wall of the second inner folded edge 203 is interference-fitted with the outer wall of the receiving edge 102.

[0034] In this embodiment: when the lid assembly 2 is docked with the packaging box 1, when the first inner folded edge 103 contacts and presses against the annular protrusion 207, the first inner folded edge 103 and the annular protrusion 207 undergo slight deformation, so that the first inner folded edge 103 can smoothly pass through the annular protrusion 207 to the top of the annular protrusion 207. The annular protrusion 207 provides a downward limit for the first inner folded edge 103, thereby fixing the lid assembly 2 and the packaging box 1.

[0035] Meanwhile, the second inner folded edge 203 and the outer wall of the receiving edge 102 press against each other, providing resistance to movement and further improving the docking stability between the cover assembly 2 and the packaging box 1.
