Description

Technical Field

[0001] This utility model relates to the field of cold chain distribution technology, specifically to a cold chain distribution insulated box structure. Background Technology

[0002] With the continuous improvement of people's living standards and increasingly stringent requirements for food quality, the cold chain logistics industry has developed rapidly. In modern society, people's demand for temperature-sensitive items such as fresh food and medicine is constantly increasing. These items need to be maintained within a specific temperature range during transportation to ensure their quality and safety. For example, fresh fruits and vegetables need to be transported in a low-temperature environment to extend their shelf life; medicines need to be transported under strict temperature control to ensure their efficacy.

[0003] Insulated boxes are the most commonly used transport containers in cold chain logistics. In current practical applications, a certain amount of refrigerant is usually placed inside insulated boxes. The main purpose of doing so is to meet the low-temperature requirements of insulated boxes during cold chain transportation and ensure the preservation effect of transported goods.

[0004] However, the refrigerant is often concentrated at the bottom of the box. This layout inevitably leads to a relatively lower temperature at the bottom and a relatively higher temperature at the top. As a result, the temperature distribution inside the insulated box becomes extremely uneven, creating a significant temperature difference.

[0005] This uneven temperature distribution poses a potential threat to the quality of transported goods. For temperature-sensitive biological products or blood products, high temperatures are highly likely to cause spoilage, affecting their efficacy and even safety. Similarly, seafood is prone to spoilage at high temperatures, which not only reduces its nutritional value but may also lead to food safety issues. Furthermore, for frozen drinks, increased temperature can significantly alter their texture, directly impacting the consumer's drinking experience.

[0006] Therefore, we propose a cold chain delivery insulated box structure to solve the above problems. Summary of the Invention

[0029] 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.

[0030] Example

[0031] like Figure 1-5As shown in the figure, an embodiment of the present invention proposes a cold chain distribution insulated box structure, including an insulation structure 1, a refrigeration structure 2 disposed on the outside of the insulation structure 1, and the insulation structure 1 and the refrigeration structure 2 being connected.

[0032] The refrigeration structure 2 includes a protective shell 201, with an inspection cover 202 hinged to the front side of the protective shell 201. Inside the protective shell 201 are a micro compressor 203, a micro condenser 204, and a micro evaporator 205. The micro condenser 204 is located in front of the micro compressor 203, and the micro evaporator 205 is located above the micro compressor 203. A communication port 209 is provided on the side of the protective shell 201 near the insulation box 101.

[0033] like Figure 2 As shown, in some embodiments, the insulation structure 1 includes an insulation box 101, a box cover 102 is movably snapped onto the top of the insulation box 101, a built-in power supply 103 is provided on the side of the insulation box 101, a charging port 104 is provided on the surface of the built-in power supply 103, and a control panel 109 is fixedly installed on the outside of the insulation box 101.

[0034] Specifically, the control panel 109 is equipped with a temperature sensor, which can monitor the temperature inside the insulation box 101 in real time. The surface of the control panel 109 is equipped with a temperature display screen and control buttons. The temperature display screen is used to display the temperature inside the insulation box 101, and the control buttons are used to control the start and stop of the micro compressor 203, micro condenser 204, micro evaporator 205 and guide fan 207.

[0035] Users can set the desired temperature range through the control buttons on the control panel 109. After receiving the control signal, the processor 208 controls the micro compressor 203, micro condenser 204 and micro evaporator 205 to start working, forming cold air. The guide fan 207 sends the cold air into the insulation box 101 through the connecting port 209 and the vent 105, so that a stable cold cavity environment is formed inside the insulation box 101, keeping the transported goods in an ideal temperature environment at all times.

[0036] like Figure 2 As shown, in some embodiments, the side end of the heat preservation box 101 is provided with a vent 105, and the heat preservation box 101 and the protective shell 201 are interconnected through the vent 105 and the connecting port 209.

[0037] Specifically, the vent 105 and the connecting port 209 are equipped with dustproof nets. The dustproof nets can effectively block external dust and impurities from entering the interior of the insulation box 101, ensuring the cleanliness of the interior of the insulation box 101. At the same time, they also protect the components inside the refrigeration structure 2, such as the miniature compressor 203, the miniature condenser 204, and the miniature evaporator 205, extending their service life.

[0038] like Figure 3 As shown, in some embodiments, a partition plate 106 is fixedly installed on the inner wall of the heat preservation box 101. The partition plate 106 divides the inner cavity of the heat preservation box 101 into a high-position placement cavity and a low-position placement cavity. A water-permeable plug 107 is provided inside the low-position placement cavity.

[0039] Specifically, the partition 106 inside the insulated box 101 can divide the inner cavity of the insulated box 101 into a high-level placement cavity and a low-level placement cavity. Users can classify and place items according to their size and type, which improves the space utilization and practicality of the insulated box 101.

[0040] Meanwhile, the water-permeable plug 107 installed inside the low-lying cavity allows users to easily clean the water inside the insulation box 101, keeping the insulation box 101 dry and hygienic.

[0041] like Figure 3 As shown, in some embodiments, the corners of the insulation box 101 are provided with reinforced corners 108, and the reinforced corners 108 are made of aluminum alloy.

[0042] Specifically, the use of reinforced corners 108 not only enhances the structural strength of the insulated box 101 and improves its impact resistance, but also makes the insulated box 101 more aesthetically pleasing. The alloy aluminum-iron material has excellent corrosion resistance and wear resistance, enabling it to adapt to various harsh transportation environments.

[0043] like Figure 5 As shown, in some embodiments, the micro compressor 203, the micro condenser 204 and the micro evaporator 205 are connected by a connecting pipe 206, the interior of which is filled with refrigerant.

[0044] Specifically, the miniature compressor 203, miniature condenser 204, and miniature evaporator 205 are connected sequentially via a connecting pipe 206, forming a loop structure. The connecting pipe 206 is filled with refrigerant. The refrigerant is compressed into vapor in the miniature compressor 203, then condensed in the miniature condenser 204. The condensed refrigerant then passes through the miniature evaporator 205, where it evaporates. During evaporation, it absorbs heat from the surrounding environment, thus lowering the temperature of the surrounding air. Simultaneously, the cooled air comes into contact with the surrounding air, forming cool air.

[0045] like Figure 5 As shown, in some embodiments, a processor 208 is fixedly snapped onto the back side of the access cover 202, and the processor 208 is electrically connected to the micro compressor 203, the micro condenser 204 and the micro evaporator 205 respectively.

[0046] Specifically, the processor 208, as the control center of the entire refrigeration system, can intelligently adjust the working status of the micro compressor 203, micro condenser 204, and micro evaporator 205 according to the temperature range set on the control panel 109, ensuring that the internal temperature of the insulated box 101 is always maintained within the set ideal range. Furthermore, the processor 208 also has a fault self-diagnosis function; once a system abnormality is detected, it will immediately issue an alarm through the control panel 109, reminding the user to check and maintain it in a timely manner, thus ensuring the reliability and safety of the cold chain delivery insulated box structure.

[0047] like Figure 5 As shown, in some embodiments, a guide fan 207 is fixedly installed on the inner wall of the protective shell 201, and the guide fan 207 is located above the micro evaporator 205.

[0048] Specifically, the cold air generated on the micro evaporator 205 is efficiently guided and evenly blown into the interior of the insulation box 101 by the guide fan 207. The precise positioning of the guide fan 207 not only ensures that the cold air can directly act on every corner of the insulation box 101,

[0049] It also improves the circulation efficiency of cold air, further enhancing the temperature uniformity and stability inside the insulation box 101.

[0050] This design allows the insulated box to maintain a constant low temperature environment during cold chain distribution, effectively extending the shelf life and quality of transported goods.

[0051] During use, the temperature sensor can monitor the temperature inside the insulation box 101 in real time. The user only needs to set the required temperature range through the control panel 109, and the processor 208 will automatically control the working status of the micro compressor 203, micro condenser 204 and micro evaporator 205 to form a stable cold air flow, and send the cold air into the insulation box 101 through the guide fan 207.

[0052] This invention utilizes a refrigerant circulation system, similar to that of an air conditioner, to achieve a cooling effect. In this invention, a miniature compressor 203 compresses the refrigerant into high-pressure vapor, which is then sent to a miniature condenser 204. In the miniature condenser 204, the high-pressure vapor exchanges heat with the surrounding environment, releasing heat and condensing into liquid refrigerant. The liquid refrigerant then flows into a miniature evaporator 205, absorbing heat from the surrounding air during evaporation, thereby cooling the air. The cooled air is then directed into the insulated enclosure 101 by a guide fan 207, forming a stable flow of cold air and maintaining a low-temperature environment inside the enclosure. This process is continuously cyclical, ensuring that the temperature inside the insulated enclosure 101 is always maintained within the set ideal range.

[0053] Furthermore, the guide fan 207 creates airflow between the insulated box 101 and the protective shell 201. This airflow not only enhances the temperature uniformity inside the insulated box 101 but also helps maintain the freshness of the air inside, preventing air quality problems caused by prolonged sealing. In addition, the airflow helps remove moisture from inside the insulated box 101, keeping the internal environment dry, which is crucial for preventing transported goods from becoming damp and deteriorating.

[0054] Users can also view the temperature data inside the insulated box 101 in real time through the control panel 109, so as to know the temperature environment of the transported goods at any time.

[0055] If the temperature exceeds the set range, the processor 208 will immediately activate the alarm mechanism and issue an audible or visual alarm through the control panel 109 to remind the user to take timely measures to adjust the temperature and ensure that the transported goods are always in an ideal temperature environment.

[0056] In summary, through the refrigeration structure 2, cold air is generated by the coordinated operation of the micro compressor 203, micro condenser 204, and micro evaporator 205. This cold air is then delivered into the interior of the insulation structure 1 via the guide fan 207. This creates a cold cavity environment similar to an air-conditioned room within the insulation structure 1, effectively improving the temperature uniformity inside the insulated box. Compared to the significant temperature differences present in traditional insulated boxes, this significantly reduces temperature variations and avoids unstable temperature environments caused by excessive temperature differences. This ensures that the transported goods remain in an ideal and stable temperature environment throughout the entire transportation process, thereby improving the preservation effect of the insulated box, enhancing its applicability, and enabling its widespread application in various transportation scenarios requiring precise temperature control, further expanding the scope of use of insulated boxes.

[0057] It should be noted that the specific models and specifications of the built-in power supply 103, micro compressor 203, micro condenser 204, micro evaporator 205, guide fan 207, and processor 208 in the cold chain delivery insulated box structure need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0058] Furthermore, the power supply and principles of the built-in power supply 103, micro compressor 203, micro condenser 204, micro evaporator 205, guide fan 207, and processor 208 in the cold chain distribution insulated box structure are clear to those skilled in the art and will not be described in detail here.

[0059] Furthermore, the working principles and wiring methods of the built-in power supply 103, micro compressor 203, micro condenser 204, micro evaporator 205, guide fan 207, and processor 208 in the cold chain distribution insulated box structure are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
