Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable preservation boxes, and in particular to a fruit and vegetable preservation box with deodorizing function. Background Technology

[0002] In today's society, with the continuous improvement of people's living standards, the demand for fresh fruits and vegetables is increasing day by day. From harvesting to reaching consumers, fruits and vegetables often need to go through a transportation and storage process of varying lengths. During this period, how to maintain the freshness and good quality of fruits and vegetables has become a key issue that urgently needs to be addressed.

[0003] Traditional fruit and vegetable packaging methods are usually quite simple, merely placing the produce in ordinary cardboard boxes, plastic crates, or basic freezer bags. During transportation, fruits and vegetables, due to their vigorous respiration, continuously consume oxygen and release gases such as carbon dioxide and ethylene. On the one hand, excessively high concentrations of carbon dioxide cause anaerobic respiration in the fruits and vegetables, producing odorous substances such as alcohol and acetaldehyde, accelerating spoilage. On the other hand, ethylene, as a plant hormone, can cause fruits and vegetables to ripen and age prematurely, not only shortening their shelf life but also potentially causing them to emit unpleasant odors due to over-ripening.

[0004] Furthermore, fruits and vegetables inevitably become contaminated with various microorganisms, such as bacteria and mold, during harvesting, handling, and transportation. This causes unpleasant odors to permeate the surrounding area and severely damages the fruit and vegetable's structure, accelerating their spoilage. Utility Model Content

[0031] Example

[0032] Reference Figures 1-4 As an embodiment of the present invention, a fruit and vegetable preservation box with deodorization function is provided, including: a layered support unit 100 and a deodorization unit 200.

[0033] The layered support unit 100 includes a box body 101 and a sealing lid 102. The box body 101 is made of food-grade plastic, which is safe, non-toxic, and has a certain strength, effectively protecting the fruits and vegetables inside. The sealing lid 102 fits tightly with the box body 101 to ensure good sealing and prevent gas from escaping. The box body 101 has several partitions 103 inside, each with a hollow structure, reducing overall weight and providing channels for air circulation. Ventilation holes 104 are provided vertically through each partition 103 to ensure smooth gas exchange between layers. A guide rod 105 is fixedly connected to the bottom partition 103, sliding sequentially through each of the upper partitions 103. This design ensures stable relative positions between the partitions 103 and allows for smooth movement along the guide rod 105 when adjusting the spacing between the partitions 103, adapting to the storage needs of fruits and vegetables of different sizes and shapes.

[0034] The layered support unit 100 also includes a scissor structure 106 disposed on the partition 103. The scissor structure 106 includes a pivot 107, a first rotating rod 108, and a second rotating rod 109. Both the first rotating rod 108 and the second rotating rod 109 are rotatably connected to the pivot 107. The ends of the first rotating rod 108 and the second rotating rod 109 in two adjacent scissor structures 106 are rotatably connected. The pivot 107 is fixedly connected to the partition 103. When the height of a partition 103 is changed by an adjustment device (such as the lifting rod 110 mentioned later), the scissor structure 106 can flexibly coordinate, so that the height of other partitions 103 connected to it can be adjusted synchronously. This ensures that the spacing between each layer of partitions 103 changes evenly, providing a precisely adapted layered space for fruits and vegetables of different shapes and sizes. This avoids fruits and vegetables from being squeezed and collided with each other due to unreasonable placement space, effectively reducing the risk of damage to fruits and vegetables during transportation and storage.

[0035] In addition, a lifting rod 110 runs through the uppermost partition 103, and the lifting rod 110 is threadedly connected to the uppermost partition 103. A dial 111 is fixedly connected to the top of the lifting rod 110, and the bottom of the lifting rod 110 abuts against the lower partition 103. Users can manually rotate the dial 111 to drive the lifting rod 110 up and down using the threaded transmission principle. The bottom of the lifting rod 110 pushes the lower partition 103 to move along the guide rod 105, thereby linking the entire scissor lift structure 106 to achieve quick and convenient adjustment of the spacing between the partitions 103. The operation is simple and efficient, meeting diverse fruit and vegetable storage needs.

[0036] In addition, a drain outlet 112 is provided on one side of the bottom of the container 101, and a plug 113 is installed inside the drain outlet 112. During the transportation and storage of fruits and vegetables, a small amount of water may accumulate due to temperature changes and the respiration of the fruits and vegetables themselves. The drain outlet 112 is designed to drain this water in a timely manner, preventing the fruits and vegetables from being soaked in water for a long time and causing them to rot and spoil. The plug 113 ensures the airtightness of the container 101 under normal circumstances and maintains a stable internal gas environment. It is only opened when drainage is needed, ensuring the overall functional integrity of the food storage container.

[0037] The core component of the deodorizing unit 200 is the mounting box 201, which is fixed to the bottom of the sealing cover 102. Air inlets 202 and outlets 203 are respectively opened on both sides of the bottom of the mounting box 201, forming a deodorizing air duct to ensure orderly airflow. An internal micro fan 204 serves as the power source; when powered on, it forcefully blows air from the air inlets 202 towards the outlets 203, promoting air circulation within the food storage container. An ozone generator 205 installed inside the mounting box 201 produces ozone, a highly oxidizing substance. Ozone effectively kills microorganisms on the surface of fruits and vegetables and decomposes odor molecules, such as oxidizing odor-producing aldehydes and alcohols into harmless carbon dioxide and water, thus reducing odors at their source.

[0038] The air inlet 202 is equipped with two interceptor plates 206, with activated carbon beads 207 positioned between them. When air is drawn in through the air inlet 202, it first passes through the activated carbon bead 207 adsorption layer. Due to its porous structure, the activated carbon beads 207 efficiently adsorb residual odor molecules and impurity particles in the air, including some microorganisms and their metabolic products, thus performing preliminary air purification. This prevents these impurities from entering the deodorizing duct and affecting the normal operation of equipment such as the ozone generator 205. It also reduces the burden on subsequent ozone sterilization and deodorization work, working in synergy with the ozone generator 205 to achieve a superior deodorization and preservation effect.

[0039] Workflow

[0040] Fruit and vegetable packing: Open the sealing cover 102, and adjust the spacing of the partitions 103 according to the type and size of the fruits and vegetables. Since the top of the lifting rod 110 is fixedly connected to the dial 111, and the lifting rod 110 is threadedly connected to the uppermost partition 103, when the dial 111 is rotated, the lifting rod 110 will move up or down according to the thread transmission principle. The bottom end of the lifting rod 110 is in contact with the lower partition 103. During the movement of the lifting rod 110, its bottom end will exert a force on the lower partition 103, pushing the two adjacent partitions 103 to slide along the guide rod 105. Through the rotational connection between the ends of the first rotating rod 108 and the second rotating rod 109 in the two adjacent scissor structures 106, the other partitions 103 connected to it will move synchronously, so that the spacing between each partition 103 changes evenly. Then, the fruits and vegetables are placed on the partitions 103 in layers to avoid squeezing. The amount of fruits and vegetables placed in each layer should be such that it does not obstruct the gas exchange of the ventilation hole 104. After the placement is completed, the sealing cover 102 is closed.

[0041] Odor removal activation: When the power is turned on, the mini fan 204 starts, drawing air from the box 101 through the air inlet 202. The air first passes through the activated carbon bead adsorption layer 207, where odor molecules and impurities are initially filtered.

[0042] Ozone sterilization and deodorization: The air that has been preliminarily purified enters the deodorization duct. The ozone generator 205 works to produce ozone. The ozone mixes with the air and flows over the surface of fruits and vegetables with the airflow, killing microorganisms and oxidizing and decomposing odor substances. The purified air returns to the box 101 from the air outlet 203, and the cycle continues.

[0043] Regular maintenance: Every so often, such as after a week of transportation or storage, open the sealed cover 102 to check the condition of the fruits and vegetables, clean the residual debris on the partition 103, and replace the activated carbon beads 207 with new ones if they are saturated to ensure that the deodorizing and preservation effect is continuous and stable.

[0044] If water is found inside the box 101, it may be due to moisture seeping out of the fruits and vegetables caused by temperature changes. Open the drain outlet 112 and plug 113 at the bottom of the box 101 to drain the water and prevent the fruits and vegetables from soaking and spoiling for a long time. After draining, plug 113 in time to maintain a sealed environment.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
