DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figures 1 to 6In the embodiment of the utility model, a moisture-proof packaging box includes an outer shell 1 with an open top, an inner shell 2 with an open top is fixed to the inner bottom surface of the outer shell 1, a cover plate 3 is provided at the open end of the outer shell 1, a compression mechanism 4 is provided between the outer shell 1 and the inner shell 2, a storage groove 21 is provided through the top surface of the inner shell 2, a square filter plate 22 is inserted into the storage groove 21, a storage shell 23 is inserted into the storage groove 21 and located inside the square filter plate 22, and the compression mechanism 4 includes four rectangular distributions and located in the inner shell 2 and the outer shell 1, the bottom end of the reciprocating screw rod 41 is rotatably connected to the inner bottom surface of the outer shell 1, and a circular pressure plate 42 is screwed together between the four reciprocating screw rods 41. The inner side surface of the inner shell 2 and the side surface of the storage shell 23 are both mesh structures. The bottom ends of the four outer side surfaces of the outer shell 1 are penetrated with a through hole 1, and the four outer side surfaces of the inner shell 2 are penetrated with a through hole 2 connected to the storage groove 21. Check valves are fixed inside the through hole 1 and the through hole 2, and an air nozzle is fixed through an inner side surface of the outer shell 1.

[0025] Specifically, firstly, a desiccant is put into the storage shell 23, and then the storage shell 23 with the desiccant is inserted into the storage slot 21, and the square filter plate 22 is inserted at the same time, and then the cover plate 3 is covered. At this time, the desiccant in the storage shell 23 can absorb the moisture in the air in the inner shell 2. Since it takes a certain amount of time for the desiccant to completely absorb the moisture in the inner shell 2, the circular pressing plate 42 can be moved up and down by rotating the four reciprocating screw rods 41. Since the bottom ends of the four outer side surfaces of the outer shell 1 are penetrated with through holes 1, the four outer side surfaces of the inner shell 2 are penetrated with through holes 2 that are connected to the storage slot 21, and the through holes 1 and 2 are connected. A one-way valve is fixed inside, so when the circular pressure plate 42 moves up, the gas in the inner shell 2 can be drawn into between the inner shell 2 and the outer shell 1, and then the gas between the inner shell 2 and the outer shell 1 is pressed out of the outer shell 1 by moving the circular pressure plate 42 downward, so that the interior of the outer shell 1 is in a vacuum state. While the gas in the inner shell 2 is drawn out, the desiccant in the storage shell 23 can absorb part of the moisture. Since there are many crushed tea leaves, when the gas in the inner shell 2 is drawn out, the crushed tea leaves are adsorbed on the square filter plate 22 with the flow of gas, which can prevent the crushed tea leaves from being contaminated with moisture and adsorbed in multiple one-way valves. Then the square filter plate 22 can be taken out and cleaned regularly.

[0026] Embodiment 1

[0027] like Figure 4-6As shown, in the present embodiment, the top surface of the cover plate 3 is fixedly connected with the shell 31, the inner bottom surface of the shell 31 is penetrated with a rotating shaft 43 extending to the inside of the outer shell 1, the reciprocating screw 41 and the end opposite to the rotating shaft 43 at the corresponding position are fixedly connected with a fixing block 45, the opposite side surfaces of the two fixing blocks 45 at the relative positions are annularly fixed with a plurality of latch teeth 46 at equal angles, the top end of the outer wall of the rotating shaft 43 is fixedly connected with a gear 1 44, the inner bottom surface of the shell 31 is rotatably connected with a support shaft, the outer wall of the support shaft is fixedly connected with a gear 2 47 meshing with four gears 1 44, and the top end of the support shaft passes through the top surface of the shell 31 and is fixedly connected with a rotating block 48.

[0028] In this embodiment, the cover plate 3 is covered on the outer shell 1, so that the multiple latching teeth 46 on the two fixed blocks 45 at the corresponding positions are engaged with each other, and then the gear 2 47 can be rotated by rotating the rotating block 48. The rotating gear 2 47 can make the four gears 1 44 rotate. The rotating gear 1 44 is engaged with each other through the multiple latching teeth 46 between the two fixed blocks 45 at the corresponding positions, so that the reciprocating screw rod 41 at the corresponding position can be rotated. The four rotating reciprocating screw rods 41 can make the circular pressure plate 42 slide up and down between the outer shell 1 and the inner shell 2, so that the gas in the inner shell 2 can be extracted, thereby preventing the moisture in the gas from making the tea leaves damp.

[0029] Embodiment 2

[0030] like Figure 2-4 As shown, in this embodiment, the bottom surface of the cover plate 3 is fixedly connected to a circular frame 32, the outer side surface of the circular frame 32 is fixed to a rubber sleeve, the length and width of the cover plate 3 are greater than the length and width of the outer shell 1, and the four sides of the outer shell 1 are rotatably connected to the locking parts 11 that are clamped with the cover plate 3, and the height of the inner shell 2 is less than the height of the square filter plate 22 and the storage shell 23.

[0031] In this embodiment, a rubber sleeve is fixed to the outer side of the circular frame 32, which can increase the sealing between the outer shell 1 and the cover plate 3. The cover plate 3 can be firmly fixed on the top surface of the outer shell 1 through the locking member 11. Since the height of the inner shell 2 is smaller than the height of the square filter plate 22 and the storage shell 23, it is convenient for people to take out the square filter plate 22 and the storage shell 23 for cleaning or replacing the desiccant.
