[0002] Tobacco leaves are the core raw material of the tobacco industry, belonging to the leaves of plants in the genus Nicotiana of the Solanaceae family. Depending on the processing method and use, tobacco leaves can be divided into various types, including flue-cured tobacco, sun-cured tobacco, air-cured tobacco, burley tobacco, and aromatic tobacco. Among these, flue-cured tobacco is the most important type of tobacco leaf in my country and is widely used in cigarette production.
[0003] Although some existing tobacco leaf storage devices have moisture-proof functions, the tobacco leaves are often piled up inside the storage box, so the tobacco leaves are prone to becoming damp and moldy when stacked together.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1-3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the moisture-proof storage device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the front view of the structure; Figure 3 for Figure 1 The enlarged schematic diagram of part A shown in the figure. The moisture-proof storage device includes: a storage box 1 with a drying box 2 installed at the bottom; a vertical plate 3 fixedly installed at the bottom of the drying box 2 and having a base plate 4; a bracket 5 installed on the inner wall of the storage box 1 and having a hanging rope 6; a clip 7 installed at the bottom of the hanging rope 6 for holding the tobacco leaves; and a drying mechanism installed on the drying box 2 for drying the air inside the storage box 1. The tobacco leaves are held by multiple clips 7, thereby suspending the tobacco leaves inside the storage box 1. The drying mechanism can reduce the humidity of the air inside the storage box 1 and prevent the tobacco leaves from getting damp.
[0021] The drying mechanism includes: a rectangular inlet 8 opened on one side of the drying box 2; an insert plate 9 installed on the rectangular inlet 8; and a metal woven mesh bag 10 fixedly installed on one side of the insert plate 9 and containing granular desiccant 11. The air is dried by the granular desiccant 11 in the metal woven mesh bag 10. The dried air re-enters the interior of the storage box 1 along the bottom of the storage box 1, thereby reducing the air humidity inside the storage box 1 and preventing the tobacco leaves from getting damp.
[0022] A sealing ring 12 is fitted on the insert plate 9, and a handle 13 is fixedly installed on one side of the insert plate 9. The sealing ring 12 can improve the sealing between the insert plate 9 and the drying box 2. The handle 13 can be used to pull the insert plate 9 and the metal woven mesh bag 10 out of the drying box 2, thereby replacing the granular desiccant 11.
[0023] A positioning mechanism is installed on one side of the storage box 1. The positioning mechanism includes: a side plate 14 fixedly installed on one side of the storage box 1; a horizontal shaft 15 rotatably installed on the side plate 14 and equipped with an L-shaped clamping plate 16; a servo motor 17 fixedly installed on the storage box 1, the servo motor 17 being of model ECMA-C20807RS; and two bevel gears 18 fixedly installed on the output shaft of the servo motor 17 and the horizontal shaft 15 respectively and meshing with each other. The servo motor 17 and the two bevel gears 18 drive the horizontal shaft 15 and the L-shaped clamping plate 16 to rotate, thereby controlling the opening and closing of the L-shaped clamping plate 16.
[0024] The storage box 1 is equipped with an air circulation mechanism, which includes: a fan 19 fixedly installed on the inner wall of the top of the storage box 1; an air guide duct 20 installed at the air outlet of the fan 19 and extending to the outside of the storage box 1; and multiple diversion pipes 21 installed on the air guide duct 20 and connected to the drying box 2. The fan 19 draws air out of the storage box 1 and guides it into the drying box 2 through the air guide duct 20 and the multiple diversion pipes 21. The air is dried by the granular desiccant 11 in the metal woven mesh bag 10. The dried air re-enters the interior of the storage box 1 along the bottom of the storage box 1, thereby reducing the humidity of the air in the storage box 1 and preventing the tobacco leaves from getting damp.
[0025] A controller 22, model ZG-ASLM, is installed on one side of the storage box 1. An air humidity sensor 23, model DHT11, is installed on the inner wall of one side of the storage box 1. The device can be controlled by the controller 22, and the air humidity sensor 23 can monitor the air humidity inside the storage box 1.
[0026] A battery compartment 24 is fixedly installed on the top of the storage box 1. A lithium battery 25 and a photovoltaic control module 28 are installed on the inner wall of the battery compartment 24. A support rod 26 is fixedly installed on the top of the battery compartment 24. A photovoltaic panel 27 is fixedly installed on the top of the support rod 26. A door 29 is hinged to the storage box 1. The device can be powered by the lithium battery 25. The photovoltaic panel 27 can convert solar energy into electrical energy and charge the lithium battery 25 through the photovoltaic control module 28.
[0027] The working principle of the moisture-proof storage device provided by this utility model is as follows:
[0028] Open the box door 29 and clamp the tobacco leaves with multiple clips 7 to suspend them inside the storage box 1. Close the box door 29 and monitor the air humidity inside the storage box 1 with the air humidity sensor 23. When the air humidity inside the storage box 1 exceeds the preset threshold, the controller 22 controls the start of the fan 19. The fan 19 draws the air out of the storage box 1 and introduces it into the drying box 2 through the air duct 20 and multiple diversion pipes 21. The air is dried by the granular desiccant 11 in the metal woven mesh bag 10. The dried air re-enters the storage box 1 along the bottom of the storage box 1, thereby reducing the air humidity inside the storage box 1 and preventing the tobacco leaves from getting damp.
[0029] When the granular desiccant 11 inside the metal woven mesh bag 10 needs to be replaced, the servo motor 17 is started. The servo motor 17 drives the horizontal shaft 15 and the L-shaped clamping plate 16 to rotate through two bevel gears 18, so that the L-shaped clamping plate 16 avoids the insert plate 9. The insert plate 9 and the metal woven mesh bag 10 are pulled out from the drying box 2 through the handle 13, so that the granular desiccant 11 inside the metal woven mesh bag 10 can be replaced. After the replacement is completed, the metal woven mesh bag 10 is inserted into the interior of the drying box 2 along the rectangular insertion hole 8. The sealing ring 12 can improve the sealing between the insert plate 9 and the drying box 2. By controlling the servo motor 17 to rotate in the opposite direction, the L-shaped clamping plate 16 is re-clamped on the insert plate 9, so as to position the insert plate 9 and the metal woven mesh bag 10.
[0030] The device can be powered by lithium battery 25, and solar energy can be converted into electrical energy by photovoltaic panel 27 and charged by photovoltaic control module 28.

A sealing ring 12 improves the seal between the insert plate 9 and the drying box 2. A handle 13 allows the insert plate 9 and the metal woven mesh bag 10 to be pulled out of the drying box 2 for replacement of the granular desiccant 11. A servo motor 17 and two bevel gears 18 drive a horizontal shaft. The L-shaped card plate 16 rotates, controlling its opening and closing. The fan 19 draws air out of the storage box 1 and guides it into the drying box 2 through the air duct 20 and multiple diversion pipes 21.
