Description

Technical Field

[0001] This utility model relates to the field of fresh food transportation technology, and in particular to a fresh food transportation device based on modified atmosphere preservation technology. Background Technology

[0002] With the improvement of people's living standards and the booming development of fresh food e-commerce, the demand for fresh product transportation is increasing day by day. Fresh products are extremely susceptible to spoilage during transportation due to oxidation, microbial growth, and other reasons, thus placing extremely high demands on preservation technology. Modified atmosphere packaging technology, by adjusting the concentration of gases such as oxygen and carbon dioxide in the transportation environment, inhibits the respiration of fresh products and the growth of microorganisms, and has become a key technology in the field of fresh food transportation.

[0003] Currently, most fresh produce transport devices on the market adopt a fixed storage space design. Their mechanical structure typically consists of a sealed box, refrigeration equipment, and simple partitions. The refrigeration equipment uses a compressor to maintain a low-temperature environment inside the box; the partitions are installed inside the box by welding or bolting and are used to separate different types of fresh produce. In terms of modified atmosphere technology, a pre-mixed gas is generally filled into the box before transportation, and the gas concentration is kept as stable as possible by sealing the box.

[0004] Existing fresh produce transportation devices cannot adjust their fixed storage space to accommodate the volume and shape of different fresh products. In actual transportation, when faced with irregularly shaped pumpkins, root vegetables, or fragile fruits such as strawberries and grapes, the inability to adapt the storage space necessitates simple stacking, leading to mutual compression of the fresh produce. On the one hand, this prevents the full utilization of the transportation device's space, reducing the capacity of a single trip and wasting transportation resources; on the other hand, the compressed fresh produce is highly susceptible to surface damage and rotting, affecting product quality and increasing spoilage costs, severely hindering the improvement of fresh produce transportation efficiency and economic benefits. Therefore, a fresh produce transportation device based on modified atmosphere storage technology is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fresh food transportation device based on modified atmosphere preservation technology, which aims to improve the problem that the fixed storage space in the existing technology cannot be adjusted according to the volume and shape of different fresh products, resulting in low transportation efficiency, especially for irregular or fragile fruits and vegetables, which are damaged by compression.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fresh food transportation device based on modified atmosphere preservation technology includes a preservation box, a rotating door rotatably connected to the side wall of the preservation box, a handle fixedly connected to the side wall of the rotating door, a slot opened in the inner wall of the preservation box, a modified atmosphere device fixedly connected inside the preservation box, a sliding plate slidably connected to the inner wall of the preservation box, and a buckle assembly provided at the bottom of the sliding plate.

[0008] The buckle assembly includes a hollow block, the top of which is fixedly connected to the bottom of the sliding plate. A locking post is slidably connected inside the hollow block. A handle is fixedly connected to one end of the locking post. The bottom of the handle is slidably connected to the bottom of the sliding plate. A spring-loaded component is provided on the outer wall of the locking post.

[0009] As a further description of the above technical solution:

[0010] The rebound assembly includes a first spring, one end of which is fixedly connected to the outer wall of the locking post, and the other end of which is fixedly connected to the inside of the hollow block.

[0011] As a further description of the above technical solution:

[0012] The sliding plate has drainage holes inside, and the drainage holes are arranged in a matrix array inside the controlled atmosphere device.

[0013] As a further description of the above technical solution:

[0014] The bottom of the food storage box is fixedly connected to a water collection trough plate, a support column is fixedly connected inside the water collection trough plate, and a water flow trough plate is fixedly connected to the top of the support column.

[0015] As a further description of the above technical solution:

[0016] A hollow column is fixedly connected inside the water collection trough plate, and a support plate is fixedly connected to the inner wall of the hollow column.

[0017] As a further description of the above technical solution:

[0018] The support plate has a fixed column that is slidably connected inside, and a baffle is fixedly connected to one end of the fixed column.

[0019] As a further description of the above technical solution:

[0020] One end of the fixed column is fixedly connected to a push column, and the outer wall of the push column is slidably connected to the inside of the hollow column.

[0021] As a further description of the above technical solution:

[0022] A second spring is provided on the outer wall of the fixed column. One end of the second spring is fixedly connected to the outer wall of the fixed column, and the other end of the second spring is fixedly connected to the side wall of the support plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pulling the handle, the locking post is slid inside the hollow block, and at the same time, the locking post is disengaged from the slot. Then, the sliding plate can be driven to slide inside the fresh food box, thereby achieving the effect of adjusting the storage space inside the fresh food box. This solves the problem that the fixed storage space cannot be adjusted according to the volume and shape of different fresh products, resulting in low transportation efficiency, especially for irregular or fragile fruits and vegetables, which are damaged by compression. This improves the space utilization rate of the fresh food transportation device.

[0025] 2. In this utility model, water from the top of the sliding plate is drained through the drainage hole and then collected by the first spring, stored inside the water collection trough. Then, pressing the pressing column drives the fixing column to slide inside the support plate, draining the water inside the water collection trough. This achieves the effect of draining water from the inside of the fresh food container, solving the problem that water accumulation inside the fresh food container cannot be effectively drained, which easily breeds bacteria, mold and other microorganisms, leading to the spoilage and decay of fresh products.

[0033] 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.

[0034] Reference Figures 1-3 An embodiment of this utility model is provided: a fresh food transportation device based on modified atmosphere preservation technology, including a fresh food box 1, a rotating door 3 rotatably connected to the side wall of the fresh food box 1, a handle 2 fixedly connected to the side wall of the rotating door 3, a slot 6 opened in the inner wall of the fresh food box 1, a modified atmosphere device 5 fixedly connected inside the fresh food box 1, and a sliding plate 19 slidably connected to the inner wall of the fresh food box 1. The sliding plate 19 is used to carry fresh products, and the buckle assembly at its bottom cooperates with the slot 6 in the inner wall of the fresh food box 1 to realize the height adjustment function. The bottom of the sliding plate 19 is provided with a buckle assembly.

[0035] The buckle assembly includes a hollow block 8, the top of which is fixedly connected to the bottom of the sliding plate 19. A locking post 9 is slidably connected inside the hollow block 8. A handle 10 is fixedly connected to one end of the locking post 9. The handle 10 slides horizontally with the locking post 9, causing the locking post 9 to disengage from the locking slot 6, thereby unlocking the device. The bottom of the handle 10 is slidably connected to the bottom of the sliding plate 19. A spring-loaded assembly is provided on the outer wall of the locking post 9. The spring-loaded assembly includes a first spring 11, one end of which is fixedly connected to the outer wall of the locking post 9, and the other end of which is fixedly connected to the inside of the hollow block 8.

[0036] Specifically, when using a fresh food transport device based on modified atmosphere storage technology, if it is necessary to adjust the internal space of the preservation box 1 to accommodate fresh products of different sizes, the following steps can be taken: First, pull the handle 10 horizontally. The handle 10 drives the locking post 9 to slide inside the hollow block 8 through the linkage mechanism, while compressing the first spring 11, causing the locking post 9 to disengage from the slot 6 on the inner wall of the preservation box 1, thereby releasing the position lock of the sliding plate 19. At this time, the sliding plate 19 can slide freely up and down along the guide rail on the inner wall of the preservation box 1. The user can flexibly adjust the distance between layers according to the actual size of the fresh food, ensuring that irregular or different sized fresh food can be placed reasonably, avoiding squeezing damage caused by fixed space. After adjusting to the appropriate position, release the handle 10. Under the action of the elastic restoring force, the first spring 11 pushes the locking post 9 back into the slot 6 at the corresponding height on the inner wall of the preservation box 1, completing the position fixation of the sliding plate 19, realizing precise control of storage space, and maximizing space utilization.

[0037] Reference Figure 1 , Figure 4 and Figure 5The sliding plate 19 has drainage holes 7 inside, which are distributed in a matrix on the surface of the sliding plate 19 to drain condensate. The drainage holes 7 are arranged in a matrix array inside the controlled atmosphere device 5. The bottom of the preservation box 1 is fixedly connected to a water collection trough plate 4. The water collection trough plate 4 is fixedly connected to a support column 12 inside the water collection trough plate 4. The top of the support column 12 is fixedly connected to a water flow trough plate 20. The water collection trough plate 4 is fixedly connected to a hollow column 13. The inner wall of the hollow column 13 is fixedly connected to a support plate 17. The support plate 17 is slidably connected to a fixed column 15. One end of the fixed column 15 is fixedly connected to a baffle 18. One end of the fixed column 15 is fixedly connected to a push column 14. The outer wall of the push column 14 is slidably connected to the inside of the hollow column 13. The outer wall of the fixed column 15 is provided with a second spring 16. One end of the second spring 16 is fixedly connected to the outer wall of the fixed column 15, and the other end of the second spring 16 is fixedly connected to the side wall of the support plate 17.

[0038] Specifically, the surface of the sliding plate 19 is equipped with a precisely designed matrix array of drainage holes 7, which efficiently guides the condensate and seepage generated by fresh products. After the water naturally drains through the drainage holes 7, it will fall precisely into the water trough plate 20. The water trough plate 20 is stably supported by the support column 12 and the surface is treated with a hydrophobic coating to ensure that the water flow can be quickly guided to the water collection trough plate 4 at the bottom of the fresh food box 1 for centralized storage. When drainage is needed, the user only needs to press the column 14. This operation will drive the fixed column 15 to slide smoothly in the hollow column 13. At the same time, the outer wall of the fixed column 15 moves along the inside of the support plate 17 to ensure accurate movement trajectory. During this process, the fixed column 15 compresses the second spring 16 and pushes the baffle 18 to move, so that the drain outlet is fully opened and the accumulated water can be quickly discharged under the action of gravity. After releasing the pressed column 14, the second spring 16 quickly and elastically returns to its original position, pulling the fixed column 15 and the baffle 18 back to their original positions. The silicone sealing ring on the edge of the baffle 18 will re-fit tightly against the drain outlet to form a reliable seal, effectively preventing external air and impurities from entering and ensuring the stability of the controlled atmosphere environment inside the chamber.

[0039] Working principle: When using the fresh food transportation device based on modified atmosphere preservation technology, and when adjusting the internal space of the preservation box 1, first pull the handle 10. The handle 10 drives the locking post 9 to slide inside the hollow block 8, and at the same time compresses the first spring 11, so that the locking post 9 disengages from the inner wall groove 6 of the preservation box 1, and releases the position lock of the sliding plate 19. At this time, the sliding plate 19 can slide up and down along the inner wall of the preservation box 1. According to the actual size of the fresh food, the interlayer distance can be flexibly changed to adapt to the storage needs of irregular and different sized fresh food, and avoid squeezing damage caused by fixed space. After adjusting to the appropriate position, release the handle 10. The first spring 11 elastically rebounds and pushes the locking post 9 to re-lock into the groove 6 at the corresponding height on the inner wall of the preservation box 1, thus completing the fixation of the sliding plate 19, accurately controlling the storage space, and improving the space utilization rate.

[0040] Subsequently, during the water collection and drainage process, a matrix array of drainage holes 7 is opened on the surface of the sliding plate 19. The generated water leaks down through the drainage holes 7 and falls into the lower water trough plate 20. The water trough plate 20 is supported by the support column 12 and guides the water flow to the bottom water collection trough plate 4 of the preservation box 1 for centralized storage. When it is necessary to drain the water in the water collection trough plate 4, press the actuating column 14. The actuating column 14 drives the fixed column 15 to slide inside the hollow column 13. At the same time, the outer wall of the fixed column 15 slides inside the support plate 17. The fixed column 15 compresses the second spring 16 and pushes the baffle 18 away from the drain outlet of the hollow column 13, and the water is discharged through the drain outlet. Release the actuating column 14, and the second spring 16 elastically resets, pulling the fixed column 15 and the baffle 18 back to reseal the drain outlet, preventing external air and impurities from entering and maintaining the preservation environment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
