[0002] Cardboard boxes are the most widely used packaging products. Different sizes and specifications of cardboard boxes can be designed according to packaging needs. After packaging, they can be stacked for storage, which is convenient for transportation and has high efficiency. Environmentally friendly cardboard boxes are packaging containers designed and manufactured with green and sustainable concepts as the core. Through innovation in materials, processes, structures and other aspects, they reduce the negative impact on the environment while meeting the functional requirements of packaging. With the improvement of health awareness, consumers have higher requirements for moisture-proof and safe packaging of food, medicine and other products.
[0003] There are many existing technologies for moisture-proof and environmentally friendly cardboard boxes, such as:
[0004] Chinese Patent (Application No.: CN202221905169.8) discloses an environmentally friendly cardboard box that is effectively waterproof and moisture-proof, comprising a box body and a lid. Mounting plates are fixedly connected to both sides of the inner surface of the box body. T-slots are formed at both ends of one side surface of the mounting plates. A T-shaped block is slidably connected to the T-slot within the T-slot. A movable plate is fixedly connected to one end of the T-shaped block. An elastic band is hinged to one side of the movable plate via a hinge plate. A fixing block is fixedly connected to the upper surface of the movable plate. A threaded groove is formed inside the fixing block. An external threaded block is threadedly connected to the threaded groove within the threaded groove. A limiting rod is fixedly connected inside the external threaded block, penetrating the fixing block and slidably connected to the penetrating part. This utility model provides an environmentally friendly cardboard box that is effectively waterproof and moisture-proof, which can limit the movement of items placed inside the box, thus facilitating the transportation of goods and is quite practical.
[0005] During storage or transportation, existing cardboard boxes often have poor air circulation, which can easily lead to moisture accumulation. This can cause irreversible damage, especially to some moisture-sensitive goods. Some cardboard boxes with ventilation openings have limited ventilation range and cannot be adjusted according to the ambient humidity and the needs of the goods. This makes it difficult to accurately control the ventilation volume inside the box, thereby reducing the moisture-proof effect of the cardboard box. Utility Model Content
[0006] This utility model addresses the technical problems existing in the prior art by providing a built-in moisture-proof and environmentally friendly cardboard box. It solves the problem that in traditional technology, the air circulation inside the cardboard box is poor, making it inconvenient to adjust the size of the ventilation openings according to the ambient humidity and the needs of the goods, which is not conducive to accurately controlling the ventilation volume inside the box and thus reducing the moisture-proof effect of the cardboard box.
[0007] To achieve the above objectives, this utility model provides a built-in moisture-proof and environmentally friendly cardboard box, comprising cardboard, with a ventilation component fixedly connected to the bottom of the cardboard. The ventilation component includes a fixed frame, with a bottom plate fixedly connected to the upper end of the fixed frame. Ventilation holes are evenly distributed inside the bottom plate. Several adjusting plates are arranged inside the fixed frame, and a movable plate is arranged inside the fixed frame. By pulling the movable plate, multiple adjusting plates are driven to rotate simultaneously inside the fixed frame, thereby adjusting the size of the ventilation openings inside the fixed frame and adjusting the amount of airflow entering the cardboard box from the ventilation holes inside the bottom plate.
[0008] The beneficial effects of this utility model are:
[0009] 1. When the ambient humidity is low and it is necessary to increase the ventilation opening and speed up the air circulation inside the carton, move the moving plate to the side closer to the fixed frame. This will cause multiple adjusting plates to rotate clockwise to the right inside the fixed frame until the adjusting plates are perpendicular to the bottom plate. At this time, the ventilation opening area is at its maximum value, which increases the ventilation volume at the bottom of the carton.
[0010] 2. When the ambient humidity is high or it is necessary to prevent external moisture from entering, the ventilation opening needs to be reduced or closed. In this case, move the moving plate away from the fixed frame, which will cause multiple adjusting plates to rotate counterclockwise to the left inside the fixed frame until the adjusting plates are parallel to the bottom plate. At this time, the ventilation opening is closed. The size of the ventilation opening can be flexibly adjusted according to the actual environmental needs to achieve the exchange of air between the inside of the box and the outside, effectively preventing moisture accumulation.

The operation is simple and convenient, highly practical, and can effectively ensure the ventilation and moisture-proof effect inside the carton.
[0016] Preferably, a support column is provided at each of the four corners of the top of the fixed frame, and several positioning rods are fixedly connected to the support column and the adjacent sides of the cardboard.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0035] Please see Figures 1-4As shown, this embodiment provides a built-in moisture-proof and environmentally friendly cardboard box, including cardboard 1. Considering that the air circulation inside the cardboard box is poor in traditional technology, it is inconvenient to adjust the size of the ventilation opening according to the ambient humidity and the needs of the goods, which is not conducive to accurately controlling the ventilation volume inside the box, thereby reducing the moisture-proof effect of the cardboard box. Therefore, a ventilation component 2 is fixedly connected to the bottom of the cardboard 1. The ventilation component 2 includes a fixed frame 21, and a bottom plate 5 is fixedly connected to the upper end of the fixed frame 21. Ventilation holes are evenly arranged inside the bottom plate 5. Several adjusting plates 23 are arranged inside the fixed frame 21, and a moving plate 25 is arranged inside the fixed frame 21. By pulling the moving plate 25, multiple adjusting plates 23 are driven to rotate simultaneously inside the fixed frame 21, thereby adjusting the size of the ventilation opening inside the fixed frame 21 and adjusting the amount of air entering the cardboard box from the ventilation holes inside the bottom plate 5.
[0036] In summary, the improvement of this embodiment lies in:
[0037] The ventilation component 2 allows for manual adjustment of the size of the ventilation openings inside the fixed frame 21 according to the ambient humidity and cargo requirements, enabling precise control of the ventilation volume inside the box. When the ambient humidity is low, the ventilation openings can be enlarged to accelerate air circulation and reduce the humidity inside the box. When the ambient humidity is high or it is necessary to prevent external moisture from entering, the ventilation openings can be reduced or closed. The operation is simple and convenient, highly practical, and can effectively ensure the ventilation and moisture-proof effect inside the carton.
[0038] Based on the above, other structures also need to be disclosed in detail, such as:
[0039] Considering that traditional cardboard boxes are mostly made of ordinary paper and lack effective moisture-proofing measures, they are highly susceptible to moisture absorption in humid environments. This causes the cardboard to soften, its strength to decrease, and its lifespan and protective function to the goods to be affected. Therefore, if... Figure 6 As shown, an outer honeycomb panel 11 is disposed inside the cardboard 1. A moisture-proof coating 12 is disposed on one side of the outer honeycomb panel 11, a cushioning layer 13 is disposed on one side of the moisture-proof coating 12, and an inner honeycomb panel 14 is disposed on one side of the cushioning layer 13. Through the multi-layer structure design of the outer honeycomb panel 11, the cushioning layer 13, and the inner honeycomb panel 14, the overall compression and impact resistance of the carton is significantly enhanced, and the structural stability is improved. By setting the moisture-proof coating 12 inside the cardboard 1, a moisture-proof barrier is formed, solving the problem of poor moisture resistance of traditional cardboard boxes.
[0040] Traditional cardboard boxes, due to their fixed structure, occupy a large amount of space during storage, recycling, or transportation, increasing warehousing and transportation costs. Therefore, creases 15 are provided on the inner and outer sides of the cardboard 1 near the bottom. This allows the cardboard 1 inside the box to be easily folded and stored by following the creases 15, reducing space occupation and improving space utilization efficiency.
[0041] To enable cardboard boxes to adjust internal airflow promptly according to ambient humidity and cargo requirements, thereby improving their moisture-proof performance, therefore... Figure 3 , Figure 4 As shown, an inner cavity 22 is symmetrically arranged inside the fixed frame 21. The two pillars of the movable plate 25 slide inside the inner cavity 22. The two ends of the adjusting plate 23 are symmetrically fixedly connected to the rotating shafts 24, which are rotatably connected to the two sides inside the fixed frame 21. Several connecting rods 26 are symmetrically fixedly connected to one side of the two pillars of the movable plate 25. Rotating parts 27 are symmetrically fixedly connected to both ends of the rotating shafts 24, and one end of the rotating part 27 is rotatably connected to the outside of the connecting rods 26. When the ambient humidity is low and it is necessary to increase the ventilation opening and accelerate the air circulation inside the carton, the movable plate 25 is moved to the side closer to the fixed frame 21. The two pillars of the movable plate 25 and the connecting rods 26 move to the right inside the inner cavity 22. Multiple adjusting plates 23 are connected to the connecting rods 26 on the pillars of the movable plate 25 through the rotating shafts 24 and the rotating parts 27, thereby driving multiple adjusting plates 23 to rotate clockwise to the right inside the fixed frame 21 until the adjusting plates 23 are perpendicular to the bottom plate 5. At this time, the ventilation opening area is at its maximum, increasing the ventilation volume at the bottom of the carton. When the ambient humidity is high or it is necessary to prevent external moisture from entering, the movable plate 25 is moved to the side closer to the fixed frame 21. The two pillars of the movable plate 25 and the connecting rods 26 move to the right inside the inner cavity 22. At this time, the ventilation opening area is at its maximum, increasing the ventilation volume at the bottom of the carton. When air enters, if it is necessary to reduce or close the vent, the moving plate 25 is moved away from the fixed frame 21. The two pillars and connecting rod 26 of the moving plate 25 move to the left inside the inner cavity 22. Multiple adjusting plates 23 are connected to the connecting rod 26 on the pillars of the moving plate 25 through the rotating shaft 24 and the rotating part 27, thereby driving multiple adjusting plates 23 to rotate counterclockwise to the left inside the fixed frame 21 until the adjusting plates 23 are parallel to the bottom plate 5. At this time, the vent is closed. The size of the vent can be flexibly adjusted according to the actual environmental needs to realize the exchange of air between the inside of the box and the outside, effectively avoiding the accumulation of moisture.
[0042] Furthermore, a fixed plate 28 is fixedly connected to one side of the fixed frame 21. Several slots 29 are provided inside the fixed plate 28. A pin 210 is provided at the top of the slot 29. After the position of the moving plate 25 is determined, in order to ensure the stability of the adjusting plate 23, the pin 210 passes through the through hole inside the moving plate 25 and engages with the slot 29 to lock the position of the moving plate 25, thereby ensuring the stability of the rotation position of the adjusting plate 23.
[0043] To improve the efficiency of rapid assembly of cardboard boxes and enhance their structural strength during use, support columns 4 are installed at the four corners of the top of the fixed frame 21. Several positioning rods 41 are fixedly connected to the adjacent sides of the support columns 4 and cardboard 1, respectively engaging with one end of each of the two cardboard 1. The support columns 4 and positioning rods 41 enable rapid positioning and connection of the two cardboard 1 joints, improving the assembly efficiency of the cardboard box. Furthermore, the support columns 4 enhance the structural strength at the four corners of the cardboard box during use, strengthening its overall compression and impact resistance and improving structural stability.
[0044] To improve the packaging efficiency of the cardboard box, a lid 3 is provided on the top of the cardboard 1, such as... Figure 5As shown, a slot 31 is provided on one side of the inside of the box lid 3, and a sealing strip 32 is fixedly connected to one side of the inside of the slot 31. The top of the cardboard 1 is engaged with the inside of the slot 31, making it easy to install and disassemble the sealing structure between the box lid 3 and the cardboard 1. The overall design fully considers the user's convenience needs during use and improves packaging efficiency.
[0045] In summary, the working principle of this solution is as follows:
[0046] First, rotate multiple cardboard pieces 1 to open the inside of the carton. Then, place four support pillars 4 at the connection between two cardboard pieces 1. The positioning rods 41 on both sides of the support pillars 4 are simultaneously engaged with one end of the two cardboard pieces 1, quickly positioning and connecting the two cardboard pieces 1. Then, place the carton lid 3 on top of the cardboard pieces 1. The top of the cardboard pieces 1 is engaged with the slot 31, connecting the cardboard pieces 1 and the carton lid 3. The overall structure is simple, improving the efficiency of carton assembly. During use, the air circulation inside the carton can be adjusted in a timely manner according to the ambient humidity and the needs of the goods. When the ambient humidity is low, it is necessary to increase the ventilation opening and accelerate the air circulation inside the carton. Then, move the moving plate 25 to the side closer to the fixed frame 21. The two pillars and connecting rods 26 of the moving plate 25 move to the right inside the inner cavity 22. Multiple adjusting plates 23 are connected to the connecting rods on the pillars of the moving plate 25 through the rotating shaft 24 and the rotating part 27. The connection 26 causes multiple adjusting plates 23 to rotate clockwise to the right simultaneously inside the fixed frame 21 until the adjusting plates 23 are perpendicular to the bottom plate 5. At this point, the ventilation area is at its maximum, increasing the ventilation volume at the bottom of the carton. When the ambient humidity is high or it is necessary to prevent external moisture from entering, and the ventilation needs to be reduced or closed, the moving plate 25 is moved away from the fixed frame 21. The two pillars and connecting rod 26 of the moving plate 25 move to the left inside the inner cavity 22. Multiple adjusting plates 23 are connected to the connecting rod 26 on the pillars of the moving plate 25 through the rotating shaft 24 and the rotating part 27, thereby causing multiple adjusting plates 23 to rotate counterclockwise to the left simultaneously inside the fixed frame 21 until the adjusting plates 23 are parallel to the bottom plate 5. At this point, the ventilation is closed. The size of the ventilation can be flexibly adjusted according to the actual environmental needs to achieve the exchange of air between the inside of the box and the outside, effectively preventing moisture accumulation and improving the moisture-proof effect of the carton.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
