Description

Technical Field

[0001] This invention belongs to the field of cold chain transportation technology, and specifically relates to a temperature-controlled insulated box. Background Technology

[0002] In the fields of pharmaceuticals, biological products, and food, a constant temperature storage and transportation environment of 2-8°C is usually required to ensure the quality of the goods to be transported and to avoid deterioration or inactivation due to temperature changes. Existing insulated boxes typically combine foam boxes with refrigerant. These boxes have limited insulation time, with the internal temperature usually exceeding 8°C within 4-6 hours. Furthermore, the refrigerant's operating time varies depending on external environmental factors. For example, in summer heat (above 35°C), the refrigerant melts quickly, failing to meet the needs of long-distance transport. The refrigerant is located within the foam box; while the temperature near the refrigerant may be within acceptable limits, the temperature further away may have exceeded them, leading to uneven temperatures and potential spoilage of items during transport. Items are usually stacked within the insulated box, and this close contact hinders air circulation, preventing the refrigerant's cooling effect from reaching the center of the stack, making items in the center more susceptible to damage. Finally, the refrigerant needs to be placed inside the box along with the items, taking up space, reducing the number of items that can be transported at once, and lowering transport efficiency. Summary of the Invention

[0003] This invention provides a temperature-controlled insulated box, which aims to solve the technical problems of existing insulated boxes having limited insulation time and being unable to meet the needs of longer-distance transportation, different temperatures in different locations leading to localized spoilage of items, and stacking items hindering the circulation of cold air.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a temperature-controlled insulation box, comprising: The main body has an insulation cavity, and an air inlet and an air return outlet located on the side wall of the insulation cavity; A refrigeration system is provided in the main body. The refrigeration system includes a refrigeration unit, an air supply duct, and a return air duct. The air supply duct is connected to the air inlet, and the return air duct is connected to the return air outlet. A power supply system is used to supply power to the refrigeration unit; A material basket is placed inside the insulation cavity. The material basket includes a basket frame and a partition located inside the basket frame. The partition has the freedom to move in the front-back direction and is used to divide the space inside the basket frame into multiple storage cavities. Ventilation gaps are provided on the side wall of the basket frame and the partition. The outer surface of the basket frame is spaced from the inner wall of the insulation cavity.

[0005] In one possible implementation, the basket has adjustable members on both sides, each adjusting member having a first mounting part that slides with the basket in a front-back direction and a second mounting part that connects to the partition.

[0006] In one possible implementation, the side wall of the basket is provided with a mounting rod extending in a front-rear direction, the first assembly part has a through hole that slides with the mounting rod, and the adjusting member also has a fastening bolt connected to the first assembly part. The fastening bolt is used to extend into the through hole and abut against the mounting rod to fix the adjusting member.

[0007] In one possible implementation, the second assembly consists of two opposing clamps that are elastic and clamp and fix the partition to the front and rear sides.

[0008] In one possible implementation, the refrigerator has a condensate inlet pipe and a condensate outlet pipe, and the refrigeration system further includes: Heat exchange box; A heat exchange plate is located inside the heat exchange box. The heat exchange plate divides the space inside the heat exchange box into a first air chamber located at the top and a second air chamber located at the bottom. The heat exchange plate is provided with through holes that connect the first air chamber and the second air chamber. The heat exchange plate is provided with a flow channel. The inlet of the flow channel is connected to the condensate inlet pipe, and the outlet is connected to the condensate outlet pipe. A fan is located at the top of the heat exchange box and communicates with the first air cavity; the fan is located on the air inlet side of the air supply duct. The second air cavity is connected to the air outlet side of the return air duct.

[0009] In one possible implementation, the air inlet is located at the top of the insulation cavity, the air return outlet is located at the bottom of the insulation cavity, and an air inlet control valve is provided at the air inlet and an air return control valve is provided at the air return outlet.

[0010] In one possible implementation, the temperature-controlled insulation box further includes: The control system is communicatively connected to the refrigeration system and the power supply system, and is used to control the refrigeration temperature of the refrigeration system and the switching of the power supply system.

[0011] In one possible implementation, the main body is provided with multiple temperature sensors, which are communicatively connected to the control system.

[0012] In one possible implementation, the main body is provided with a display, and the control system is integrated into the display. The display is used to display the detected temperature of the temperature sensor, the cooling temperature of the refrigeration system, and the power status of the power supply system.

[0013] In one possible implementation, the main body is provided with casters at the bottom, a pull rod at the top, and a hand strap on the side.

With the power supply system to power the refrigeration system, it can ensure the long-term operation of the refrigeration system, which can adapt to the needs of long-distance transportation. Moreover, the working time and duration of the refrigeration unit can be flexibly adjusted through the power supply system, thereby achieving flexible control of the refrigeration temperature, ensuring that the refrigeration time is extended with low energy consumption and ensuring the refrigeration effect. The ventilation gaps in the basket and partitions can ensure sufficient circulation of cold energy, avoiding the deterioration of items due to lack of cold energy in some areas caused by the accumulation of items. In addition, the position of the partitions is adjustable to accommodate items of different sizes. Items can also be classified and stored according to size, category, shape, etc., and placed in different storage cavities, making it more flexible to use. Attached Figure Description

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0021] Please refer to the following: Figures 1 to 7The temperature-controlled insulated box provided by the present invention will now be described. The temperature-controlled insulated box includes a main body 10, a refrigeration system 20, a power supply system 30, and a material basket 40. The main body 10 has an insulated cavity 11, and an air inlet 12 and an air return outlet 13 located on the side wall of the insulated cavity 11. The refrigeration system 20 is located in the main body 10 and includes a refrigeration unit 21, an air supply duct 22, and an air return duct 23. The air supply duct 22 is connected to the air inlet 12, and the air return duct 23 is connected to the air return outlet 13. The power supply system 30 is used to supply power to the refrigeration unit 21. The material basket 40 is placed in the insulated cavity 11. The material basket 40 includes a basket 41 and a partition 42 located in the basket 41. The partition 42 has a degree of freedom to move in the front-back direction and is used to divide the space in the basket 41 into multiple storage cavities. Ventilation gaps are provided on the side wall of the basket 41 and the partition 42. The outer surface of the basket 41 is spaced from the inner wall of the insulated cavity 11.

[0022] It should be noted that the position of the partition 42 can be adjusted according to the size of the items to be transported. One or more partitions 42 can be set. According to the adjustment of the position of the partition 42, the space size of multiple storage compartments can be the same or different, so as to accommodate the placement of items of different sizes. Furthermore, according to the size, shape, category and other conditions of the items, they can be placed into different storage compartments, which can also facilitate classification and storage, and make it easier to take them out.

[0023] Specifically, to facilitate the placement and retrieval of items, the main body 10 is provided with an openable and closable cover 18 at the position corresponding to the insulation cavity 11. The cover 18 is rotatably connected to the main body 10 via a hinge, and a sponge strip can be installed on the side where the hinge is installed to prevent cold air loss. On the side of the cover 18 opposite to the hinge, it can be connected to the main body 10 by a structure such as a buckle or a magnet to ensure that the cover 18 is not easy to open when it is locked, thus ensuring the refrigeration effect and preventing items from falling out. To further improve security (for example, if the items to be transported are vaccines or other high-security categories), a lock (either an electronic lock or a mechanical lock) can also be installed between the cover 18 and the main body 10.

[0024] Specifically, the top of the insulation cavity 11 is provided with a groove, and the corresponding cover 18 has a raised structure corresponding to the groove. When the cover 18 is closed, the top of the insulation cavity 11 can be sealed to reduce the loss of cold energy.

[0025] In the specific operation of the temperature-controlled insulated box provided in this embodiment, the items to be transported are placed in the material basket 40, the position of the partition 42 is adjusted according to the size of the items, and the items are placed in the corresponding storage chamber. The refrigeration unit 21 generates cold air, which enters the insulation chamber 11 through the air supply duct 22 and the air inlet 12. The cold air enters the material basket 40 and circulates inside, thereby refrigerating the items in the material basket 40. Then, it returns to the refrigeration system 20 through the return air vent 13.

[0026] In the prior art, large transport vehicles do not carry small quantities of items that require refrigeration. However, the temperature-controlled insulated box of this application enables the transport of small quantities of items that require refrigeration.

[0027] Compared with existing technologies, this embodiment, compared with the traditional passive insulation method of foam box + cold storage agent, actively generates cold energy through the refrigeration system 20 and realizes air circulation in the insulation cavity 11, which can extend the insulation time and enhance the insulation effect. With the power supply system 30 supplying power to the refrigeration system 20, the refrigeration system 20 can be operated for a long time, which can meet the needs of long-distance transportation. Furthermore, the working time and duration of the refrigeration unit can be flexibly adjusted through the power supply system 30, thereby achieving flexible control of the refrigeration temperature, ensuring that the refrigeration time is extended with low energy consumption and ensuring the refrigeration effect. The ventilation gaps on the basket 41 and the partition 42 can ensure sufficient circulation of cold energy, avoiding the deterioration of items due to lack of cold energy in some areas caused by the accumulation of items. The position of the partition 42 is adjustable to accommodate items of different sizes, and items can be classified and stored according to size, category, shape, etc., and placed in different storage cavities, making it more flexible to use. By setting the air inlet 12 and the air return vent 13 in the insulation cavity 11, the space inside the insulation cavity 11 is not occupied, which can improve the transportation efficiency of items.

[0028] In some embodiments, the power supply system 30 is a storage battery. The storage battery and the refrigerator 21 can be electrically connected by wires. A control switch can be set on the connecting wire between the storage battery and the refrigerator 21 to facilitate the control of the start-up and shutdown of the refrigerator 21 and its working time. The storage battery also has a charging interface 31 located on the main body 10 to facilitate charging when the battery power is low and to facilitate repeated use.

[0029] Considering the actual transportation time, the battery capacity must be sufficient to keep the insulation cavity 11 warm for at least 24 hours.

[0030] To improve the safety of the insulation box, the battery and refrigeration unit 21 may generate heat during operation. Both the battery and refrigeration unit 21 are located inside the outer shell of the main body 10. A heat dissipation window can be provided on the side of the outer shell of the main body 10 opposite to the insulation cavity 11, corresponding to the position of the battery. Similarly, a heat dissipation window can be provided on the side of the outer shell of the main body 10 opposite to the position of the refrigeration unit 21, which facilitates heat dissipation of the battery and refrigeration unit 21, avoids overheating damage, and also avoids the risk of fire.

[0031] In order to prevent the heat generated by the battery and the refrigeration unit 21 during operation from affecting the temperature inside the insulation cavity 11, a certain distance can be maintained between the battery and the insulation cavity 11, and between the refrigeration unit 21 and the insulation cavity 11. Insulation material is also provided on the side wall of the insulation cavity 11 to extend the insulation time of the insulation cavity 11.

[0032] In some embodiments, in order to facilitate the placement of items in the material basket 40, a handle can be provided on the material basket 40. The handle makes it easy to take the material basket 40 out of the insulation cavity 11. Before the items are put into the insulation cavity 11, the material basket 40 can be taken out. After the items are placed in the material basket 40, the material basket 40 can be put back into the insulation cavity 11 for easy operation.

[0033] Specifically, the structure of the handle and the connection between it and the material basket 40 can be referenced from the handle of a plastic bucket.

[0034] In some embodiments, an improved implementation of the above-described material basket 40 may employ, as follows: Figures 3 to 4 The structure shown. See also Figures 3 to 4 The basket 41 has adjusting parts 43 on both sides. Each adjusting part 43 has a first mounting part that slides with the basket 41 in the front-back direction and a second mounting part that connects to the partition 42. The adjusting parts 43 can be moved to their positions before installing the partition 42, and then the partition 42 can be installed on the corresponding adjusting parts 43, facilitating the positioning and installation of the partition 42; alternatively, the partition 42 can be installed on the adjusting parts 43 first, and then its position can be moved. Since the partition 42 is larger, adjusting it requires less effort. Using adjusting parts 43 for partition 42 installation allows for flexible adjustment of its position, making it more convenient to use.

[0035] It should be noted that multiple adjusting components 43 are installed on each side of the basket 41. When installing the partition 42, the number of partitions 42 can be less than the number of adjusting components 43. For example, if there are 5 adjusting components 43 on each side, only one partition 42 is installed when installing the partition 42 because there are few types of items. This arrangement allows for flexible adjustment of the number of partitions 42. When it is necessary to add more partitions 42, the partitions 42 can be installed directly, which saves more time compared to the combined installation of partitions 42 and adjusting components 43.

[0036] In some embodiments, a specific implementation of the first assembly unit described above may adopt the following approach: Figure 4 The structure shown. See also Figure 4The basket 41 has a mounting rod 411 extending in the front-to-back direction on its side wall. The first assembly part has a through hole that slides with the mounting rod 411. The adjusting member 43 also has a fastening bolt 44 connected to the first assembly part. The fastening bolt 44 extends into the through hole and abuts against the mounting rod 411 to fix the adjusting member 43. The adjusting member 43 is fitted onto the mounting rod 411. When adjustment is needed, the fastening bolt 44 is loosened, and the position of the adjusting member 43 is changed by sliding along the axial direction of the mounting rod 411. After moving to the appropriate position, the fastening bolt 44 is tightened, ensuring that the position of the partition 42 connected to the adjusting member 43 is fixed. This prevents the partition 42 from shaking and squeezing items during transportation, ensuring the reliability of the separation and reducing transportation losses.

[0037] Mounting rods 411 are provided on both the left and right sides of the basket 41. To facilitate the installation of the adjusting parts 43, both ends of the mounting rods 411 can be detachably connected to the basket 41. After a certain number of adjusting parts 43 are installed on the mounting rods 411, they can be installed on the basket 41 to achieve the cooperation between the adjusting parts 43 and the basket 41.

[0038] As an alternative implementation, the left and right sides of the basket 41 can be provided with sliding grooves extending in the front-back direction. The first assembly part is a slider that slides in the sliding groove. In order to ensure that the second assembly part slides normally with the first assembly part, the side of the sliding groove facing the second assembly part also needs to have an extension groove for the second assembly part to extend out. The extension groove also needs to extend in the front-back direction. In this embodiment, if it is desired to fix the adjusting member 43, a through groove extending in the front-back direction can also be provided on the side of the sliding groove away from the second assembly part. The slider is provided with an internal threaded hole. By using a bolt to pass through the through groove and connect and tighten with the internal threaded hole on the slider, the position of the adjusting member 43 can be fixed.

[0039] In some embodiments, a specific implementation of the second assembly unit described above may adopt the following approach: Figure 4 The structure shown. See also Figure 4 The second assembly consists of two opposing clamping pieces 45. These clamping pieces 45 are elastic and clamp and fix the partition 42 to its front and rear sides. The clamping pieces 45 can be spring plates. The two clamping pieces 45 gradually approach each other in the direction away from the first assembly, thereby forming a certain elastic clamping force. When installing the partition 42, the two clamping pieces 45 are pried apart, and the partition 42 is placed between them. Releasing the clamping pieces 45 will cause them to elastically rebound, thus achieving the cooperation of the two clamping pieces 45 to clamp the partition 42. This structure facilitates the installation of the partition 42, eliminating the need for bolt tightening and other actions, making the operation labor-saving and relatively simple.

[0040] As an alternative implementation, the second assembly part can also be a magnet, with magnetic blocks corresponding to the magnet provided on the left and right sides of the partition 42, so that the partition 42 can automatically magnetically engage with the second assembly part when it is placed in, thereby fixing the position of the partition 42.

[0041] In some implementations, an improved embodiment of the above-described refrigeration system 20 may employ, as follows: Figure 2 The structure shown. See also Figure 2 The refrigeration unit 21 has a condensate inlet pipe 24 and a condensate outlet pipe 25. The refrigeration system 20 also includes a heat exchange box 26, a heat exchange plate 27, and a fan 28. The heat exchange plate 27 is located inside the heat exchange box 26 and divides the space inside the heat exchange box 26 into a first air chamber located at the top and a second air chamber located at the bottom. The heat exchange plate 27 has through holes that connect the first air chamber and the second air chamber. The heat exchange plate 27 has a flow channel. The inlet of the flow channel is connected to the condensate inlet pipe 24, and the outlet is connected to the condensate outlet pipe 25. The fan 28 is located at the top of the heat exchange box 26 and is connected to the first air chamber. The fan 28 is located on the air inlet side of the air supply duct 22. The second air chamber is connected to the air outlet side of the return air duct 23.

[0042] The refrigeration unit 21 generates condensate, which enters the circulation channel through the condensate inlet pipe 24. When the air in the second air chamber enters the first air chamber through the through hole, it passes through the heat exchange plate 27 and is cooled. Therefore, the air temperature in the first air chamber is lower than the air temperature in the second air chamber. The fan 28 carries the cold air in the first air chamber out and transmits it to the air inlet 12 and into the insulation chamber 11. According to the working principle of the fan 28, it can be seen that the fan 28 blows air on one side and draws air on the opposite side, thereby causing the second air chamber connected to the return air inlet 13 to draw air in and draw the hot air in the insulation chamber 11 back to the heat exchange box 26, realizing the circulation of air. Through the above process, the medicine in the insulation chamber 11 is circulated and cooled to maintain a constant temperature.

[0043] Insulation and refrigeration are achieved by combining the heat exchange plate 27 with the refrigeration unit 21. The condensate enters the heat exchange plate 27, which can increase the heat exchange area and improve the cooling efficiency of the air in the second air cavity when it passes through the heat exchange plate 27. The fan 28 accelerates the air circulation and further reduces the temperature gradient in the insulation cavity 11.

[0044] It is easy to imagine that the condensate in the refrigeration unit 21 returns to the refrigeration unit 21 after passing through the flow channel, and this circulation process can be achieved by pumps or the like.

[0045] In some embodiments, an improved implementation of the above-described temperature-controlled insulation box can be as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2The air inlet 12 is located at the top of the insulation cavity 11, and the return air inlet 13 is located at the bottom of the insulation cavity 11. An air inlet control valve 121 is provided at the air inlet 12, and a return air control valve 14 is provided at the return air inlet 13. Based on the principle of cold air sinking, the air inlet 12 is set at the top of the insulation cavity 11. After the cold air enters the insulation cavity 11, it will pass through the ventilation gaps and the gaps between the items, so that the items in different positions in the insulation cavity 11 are in the same temperature environment. After the cold air sinks, the temperature of the items will rise accordingly. At this time, it just reaches the position of the return air vent 13. The return air vent 13 draws out the cold air with the increased temperature, passes through the refrigeration system 20, and then blows it back into the insulation cavity 11. During use, the temperature and refrigeration status in the insulation cavity 11 can be easily adjusted by adjusting the size of the air inlet control valve 121 and the return air control valve 14. For example, when not in use, the air inlet control valve 121 and the return air control valve 14 are closed. When the temperature in the insulation cavity 11 rises, the temperature in the insulation cavity 11 is lowered by adjusting the opening degree of the air inlet control valve 121 to be greater than the opening degree of the return air control valve 14.

[0046] In some embodiments, a specific implementation of the above-described material basket 40 may adopt the following approach: Figures 3 to 6 The structure shown. See also Figures 3 to 6 The four sides and bottom walls of the basket 41 are all grid structures, and the partition 42 is also a grid structure, thus forming the above-mentioned ventilation gap; and in order to ensure that there is a gap between the outer surface of the basket 41 and the inner wall (including the bottom wall and side wall) of the insulation cavity 11 after the basket 41 is placed in the insulation cavity 11, support feet can be set at the bottom of the basket 41.

[0047] In some embodiments, an improved implementation of the above-described temperature-controlled insulation box can be as follows: Figure 7 The structure shown. See also Figure 7 The temperature-controlled insulation box also includes a control system 50, which is communicatively connected to the refrigeration system 20 and the power supply system 30. The control system 50 is used to control the refrigeration temperature of the refrigeration system 20 and the switching on and off of the power supply system 30.

[0048] By adding a control system 50, communication with the refrigeration system 20 and the power supply system 30 can be achieved via wires or wireless signals. This allows for setting and controlling the refrigeration temperature of the refrigeration system 20, as well as controlling the switching on and off of the power supply system 30. The control system 50 can replace manual adjustment, achieving precise temperature control and avoiding temperature exceedances due to human error. Furthermore, it can automatically start and stop the refrigeration unit 21 according to the set temperature, reducing energy consumption and extending battery life.

[0049] In some embodiments, an improved implementation of the aforementioned body 10 may employ, as follows: Figure 1 The structure shown. See also Figure 1The main body 10 is equipped with multiple temperature sensors 60, which are communicatively connected to the control system 50. The multiple temperature sensors 60 can be installed at different positions within the insulation cavity 11. By determining the temperature detected by the multiple temperature sensors 60, the precise temperature conditions within the insulation cavity 11 can be determined, thereby facilitating the control system 50 to accurately adjust the refrigeration system 20.

[0050] In some embodiments, an improved implementation of the above-described temperature-controlled insulation box can be as follows: Figure 1 The structure shown. See also Figure 1 The main body 10 is equipped with a display 70, and the control system 50 is integrated into the display 70. The display 70 is used to display the detected temperature of the temperature sensor 60, the cooling temperature of the cooling system 20, and the power status of the power supply system 30. Users can intuitively obtain key information through the display 70, which facilitates real-time monitoring of the insulation status and timely detection of abnormalities. The integrated design reduces the number of components, lowers the risk of failure, and improves the ease of use of the equipment.

[0051] Specifically, the core components of the control system 50 include: (1) Microcontroller (MCU): As the control center, a single-chip microcomputer (such as STM32 series) or embedded chip can be used to receive sensor data and execute control logic (such as adjusting the power of the refrigerator 21 according to the temperature difference).

[0052] (2) Communication module: including connection interfaces (such as GPIO, UART, I2C, etc.) with refrigeration system 20 (refrigeration unit 21, fan 28, control valve), power supply system 30 (such as battery) and temperature sensor 60, to realize data transmission and command issuance.

[0053] (3) Display 70: integrates the functions of the control system 50, and uses an LCD or OLED screen to visually display information such as temperature and power.

[0054] (4) Operation buttons / touch panel: located next to the display 70, for users to set the target temperature (e.g., 2-8℃), start / stop the device, etc.

[0055] (5) Temperature control algorithm: Based on the real-time data of multiple temperature sensors 60, the output power of the refrigerator 21, the speed of the fan 28 and the opening of the air valve are dynamically adjusted through the PID (proportional-integral-derivative) algorithm to keep the temperature of the insulation cavity 11 stable within the set range.

[0056] (6) Status monitoring program: Real-time collection of power supply system 30 power and chiller 21 operating status (such as whether it is faulty), and update information on display 70; when an abnormality occurs (such as temperature exceeding the standard, power too low), an alarm is triggered (such as audible and visual prompts).

[0057] In order to achieve the linkage between the refrigeration system 20 and the control system 50, the refrigeration system 20 needs to be equipped with the following modules: (1) Main control module (such as MCU submodule) Function: As the local control core of the refrigeration system 20, it receives instructions from the control system 50 (such as refrigeration temperature, start / stop signals, and fan speed adjustment), and coordinates the actions of various components within the system.

[0058] Linkage function: Transform the abstract instructions of the control system 50 (such as "cool down to 5℃") into specific execution signals (such as compressor power adjustment, fan speed 28 switching).

[0059] (2) Driver module This includes: a compressor drive module (for a compressor-type refrigerator 21, such as a PWM speed control module), a fan 28 drive module (such as a DC motor drive chip L298N), and a valve drive module (such as a servo / solenoid valve drive circuit).

[0060] Function: Converts the low-voltage signals (such as 5V control signals) of the main control module into high-voltage drive signals to control the operation of the compressor of the refrigeration unit 21, the circulating fan 28, and the inlet / outlet air control valve 14 (such as start / stop, speed / opening adjustment).

[0061] Linkage function: Responding to the "cooling intensity adjustment" command of the control system 50, for example, when the control system 50 detects that the temperature of the insulation cavity 11 is too high, the drive module increases the compressor power and the fan speed 28.

[0062] (3) Status monitoring module Includes: temperature sensor 60 (such as NTC thermistor, DS18B20, to monitor condensate temperature and heat exchange plate 27 temperature), pressure sensor (to monitor condensate pressure in refrigeration system 20), and operating status sensor (such as Hall sensor to detect whether compressor / fan 28 is running).

[0063] Function: Real-time acquisition of key parameters of the refrigeration system 20 (such as refrigeration efficiency and whether components are working properly) and feedback to the control system 50 via the communication module.

[0064] Linkage function: When the sensor detects "abnormal condensate pressure" or "fan 28 stops running", it promptly transmits the fault information to the control system 50 and triggers an alarm (such as a prompt on the display 70).

[0065] (4) Communication module Type: Wired communication (such as UART, I2C, RS485, suitable for short-range stable connections) or wireless communication (such as Bluetooth BLE, suitable for modular designs).

[0066] Function: Establishes a data transmission channel between the refrigeration system 20 and the control system 50 to receive instructions (such as "start refrigeration") and upload status (such as "current refrigeration temperature 8℃").

[0067] In order to achieve the linkage between the power supply system 30 and the control system 50, the power supply system 30 needs to be equipped with the following modules: (1) Battery Management Module (BMS, suitable for battery-powered scenarios) Functions: Real-time monitoring of battery voltage, current, remaining charge (SOC), and temperature; protection against overcharge, over-discharge, and overcurrent; and calculation of battery life.

[0068] Linkage function: The power data (such as "remaining power 30%) is transmitted to the control system 50 through the communication module. When the power is lower than the threshold, the control system 50 can instruct the refrigeration system 20 to enter the energy-saving mode.

[0069] (2) Power conversion module Includes: AC / DC conversion module (converts 220V AC mains power to the DC voltage required by the equipment, such as 12V or 5V), and DC / DC voltage regulator module (stabilizes the output voltage and avoids fluctuations affecting the equipment).

[0070] Function: Provides stable voltage for the refrigeration system 20, control system 50, and display 70, and supports parallel power supply for multiple devices.

[0071] Linkage function: Receives "power switching command" (such as switching from mains power to backup battery) from control system 50 to ensure continuous power supply in extreme situations.

[0072] (3) Status feedback module Includes: power indicator (LED) and power mode sensor (detects whether the current power supply is AC or battery power).

[0073] Function: Converts the power supply status (such as "mains power interrupted, switch to battery") into an electrical signal and feeds it back to the control system 50 through the communication module.

[0074] Linkage function: The control system 50 supports the real-time display of "power supply mode" and "remaining battery life" on the display 70 to help users judge the feasibility of transportation.

[0075] (4) Communication module Similar to the cooling system 20, wired communication methods such as UART or I2C are used to achieve data interaction with the control system 50 (such as uploading power data and receiving power control commands).

[0076] In some embodiments, an improved implementation of the aforementioned body 10 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The main body 10 is equipped with casters 15 at the bottom, a pull rod 16 at the top, and a handle 17 on the side. The casters 15 at the bottom facilitate dragging via the pull rod 16, and the handle 17 can be used for operation in scenarios requiring transportation. It is also suitable for scenarios with uneven roads in some remote areas, adaptable to various modes of movement and transportation environments, and reduces the difficulty of manual operation.

[0077] It should be noted that the caster wheel 15 can be configured as a self-locking caster wheel 15, which makes it easy to lock when not in use.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
