[0026] The technical solutions in the utility model will be further explained in connection with the drawings and embodiments.

[0027] As Figures 1 to 5 shown, according to the embodiment of the utility model, a lithium battery storage box, including the inside is equipped with the storage space's rectangular box body 1, the box body 1 one side is equipped with the box door 11 that opens outwardly to rotate, the box body 1 inner side wall is horizontally and in parallel and is equipped with several groups of slide rails 12, the slide rail 12 is equipped with the storage drawer 13 that slides, the storage drawer 13 is towards the box door 11 and can slide to the outside of the box body 1;

[0028] As Figures 1 to 5 shown, the box body 1 bottom is further provided with horizontal first air duct 2 and the second air duct 3 connected with it, the first air duct 2 is rectangular cylindrical structure, one end is connected on the inner wall of the box body 1 and is open and penetrates to the outside of the box body 1, the other end extends to the central region of the bottom of the box body 1 and is closed, the both sides of the closed end of the first air duct 2 are further provided with first air inlet 21, the second air duct 3 is rectangular cylindrical structure, one end is open and closed and fixedly connected on the first air inlet 21, the other end is closed, the inner wall of the top of the second air duct 3 is further provided with second air inlet 31, the position of the first air inlet 21 is further provided with first fan 22 for sucking air, the position of the second air inlet 31 is further provided with second fan 32 for sucking air, two fans continuously suck air and deliver to the inside of the box body 1;

[0029] As Figure 1 and Figure 2 shown, the top of the box body 1 is further provided with several heat dissipation openings 18, the heat dissipation fan 19 is further provided on the heat dissipation opening 18, the heat dissipation fan 19 can refer to the brushless motor 4 fan for the computer mainframe to dissipate heat, the structure of this fan is relatively simple and the power is relatively low, can omit the external motor 4, and because the heat in the box body 1 is slowly accumulated, it is not necessary to run very high power, only needs to ensure that air circulates to meet the heat dissipation condition.

[0030] As Figure 1 and Figure 5As shown, the first air duct 2 is also slidingly provided with a water absorption cylinder 5 and a plurality of water vapor absorption layers arranged in the water absorption cylinder 5. The water absorption cylinder 5 is arranged in a rectangular cylinder shape and has a length smaller than that of the first air duct 2 and can be inserted into the first air duct 2. One end of the water absorption cylinder 5 is provided with a cylinder cover 6, and a plurality of air holes 61 are arranged through the cylinder cover 6. The other end of the water absorption cylinder 5 is open. Air enters the air holes 61, then passes through the water vapor absorption layers in the space inside the water absorption cylinder 5, and is then sucked by the first fan 22 from the open end of the water absorption cylinder 5, and then passes through the second air duct 3 and is sent into the box 1 from the second fan 32.

[0031] The first fan 22 and the second fan 32 and the heat dissipation fan 19 are arranged in the box 1 for storing lithium batteries to guide air flow and dissipate heat. An air moisture absorption layer is arranged in front of the fan for air intake to solve the problem of moisture, so that the air sucked into the box 1 by the fan is dry.

[0032] When the staff needs to store the battery, the box door 11 is opened, the storage drawer 13 is pulled out, the battery is placed on the drawer, the drawer is pushed into the box 1, the box door 11 is closed, then the cylinder cover of the water absorption cylinder 5 is opened, the plurality of water vapor absorption layers are placed in the water absorption cylinder 5 in sequence and the cylinder cover is closed, the water absorption cylinder 5 is inserted into the first air duct 2, and finally the first fan 22, the second fan 32 and the heat dissipation fan 19 are turned on to guide the air flow, which can solve the problem of heat dissipation of the battery after the battery is heated due to the lack of air circulation, and can prevent the problem of water vapor invading the box for storing the battery due to the large moisture in the south, the high air humidity in the plum rain season or the rainy and snowy weather.

[0033] Further, as shown in FIG. 6, the box 1 is provided with a plurality of storage drawers 13, and each storage drawer 13 is provided with a plurality of battery storage spaces 14. Figure 2 and Figure 3As shown, the storage drawer 13 comprises a bottom plate 14, both sides of the bottom plate 14 are slidingly arranged on the slide rail 12, a plurality of mesh holes 17 penetrating through the bottom plate 14 are uniformly arranged on the bottom plate 14, and a plurality of insulation strips 15 are arranged on the upper surface of the bottom plate 14 in a cross shape. The insulation strips 15 are arranged in a horizontal and vertical manner to form storage positions 16 corresponding to the size of the battery. The drawer type increases the practicability of the staff for taking and placing. The connection mode of the slide rail 12 and the drawer can refer to the rolling connection mode of the existing drawer type drawer. The mesh holes 17 are arranged on the bottom plate 14, so that the flowing air can flow from the bottom to the top of the battery to carry away the heat as much as possible. Since the positions for storing the battery are actually arranged in a cross shape by the insulation strips 15, the insulation strips 15 can be adhered to the bottom plate 14 by an adhesive. The storage positions 16 of each storage drawer 13 can be pre-set in size according to different batteries, and then the insulation strips 14 are adhered and simultaneously divided into corresponding battery sizes. The storage of the battery is more comprehensive, the practicability is improved, and the battery is not easily shaken. The insulation strips 15 can be made of rubber or plastic. Some point-shaped protrusions can be arranged on the surface of the insulation strips 15, so that there is a gap between the battery and the insulation strips. While ensuring that the storage position 16 can store the battery, the flowing air can pass through the gap and carry away the heat.

[0034] Further, as shown in Figure 1 and Figure 5 , the outer wall position of the closed end of the second air duct 3 is also provided with a motor 4, and the output end of the motor 4 is also fixedly connected with a first rotating shaft 41. The first rotating shaft 41 extends through the second air duct 3 and is coaxially fixedly connected with the first fan 22. The position of the first rotating shaft 41 corresponding to the second fan 32 is also provided with a universal joint 43, which is a bevel gear structure. The universal joint 43 also extends out of the second rotating shaft 42 perpendicular to the first rotating shaft 41, and the second rotating shaft 42 is in a vertical state. After the direction is changed by the bevel gear structure, the second rotating shaft 42 is coaxially fixedly connected with the second fan 32. The above mechanism can control the first and second fans 32 by one motor 4. As shown in Figure 5 , since the water absorption cylinder 5 is provided with three layers of water vapor absorption layer, a certain power is required to suck air from the other side of the water vapor absorption layer to this side, so the motor 4 is selected to drive. However, the power of the motor 4 can still be kept at a low state to work while reducing noise and saving power.

[0035] Further, as shown in Figure 5As shown, the water vapor absorption layer has three layers: a rectangular waterproof and breathable fabric layer 51, which is woven from a polymer membrane and fabric. Its water absorption and breathability principle is similar to capillary action. In the water vapor state, the water particles are very small and, according to the principle of capillary action, can easily penetrate to the other side of the capillary channel, thus causing vapor permeation. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull and resist" each other), the water molecules cannot easily detach from the water droplets and penetrate to the other side, thus preventing water penetration. This gives the breathable membrane a waterproof function, while also providing breathability due to the composite weaving of the fabric.

[0036] The rectangular imitation cashmere fabric layer 52 is produced by imitating the water absorption and breathability principle of cashmere. It also uses the capillary principle, but has a higher total water absorption capacity and better breathability, and absorbs excess moisture on the waterproof and breathable fabric layer 51.

[0037] The rectangular desiccant layer 53 uses activated carbon-type desiccant to absorb moisture from the air. It also has good porosity and air permeability. All three water-absorbing layers are set inside the rectangular frame 54, which is made to the size of the water-absorbing cylinder 5. The rectangular frame 54 can be wrapped with a support mesh bag. When in use, simply insert the rectangular frame 54, which already contains the water-absorbing material, into the water-absorbing cylinder 5. This allows the water-absorbing layer to be put in and taken out of the water-absorbing cylinder 5. After the water-absorbing layer is inserted, the water-absorbing cylinder 5 is inserted into the first air duct 2. When it is necessary to replace the water-absorbing layer, the water-absorbing cylinder 5 can be pulled out directly and the water-absorbing layer can be replaced (remove the rectangular frame 54) to replace the new water-absorbing layer.

[0038] Furthermore, the cap 6 is detachably mounted on the end of the suction cylinder 5, and one side of the cap 6 can be rotatably connected to the end of the suction cylinder 5 by means of a hinge, such as... Figure 1 As shown, a limiting protrusion is provided on the inner wall of the water absorption cylinder 5 near the end without a cylinder cover to restrict the position of the water vapor absorption layer and prevent the water absorption layer from falling out of the water absorption cylinder 5.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
