[0012] The above scheme has the following beneficial effects:

[0013] 1. The refrigeration compartment can provide a stable low-temperature storage environment for the vaccines, ensure the quality and effectiveness of the vaccines, the plurality of vaccine storage compartments are communicated with the refrigeration compartment, the temperature in each storage compartment can be kept balanced, and the influence of local high or low temperature on the storage of the vaccines is avoided; when the vaccines are taken out, the circulation of the external air and the air in the compartment will affect the temperature in the compartment, the change of the temperature will affect the activity of the vaccines, the vaccines are stored in different zones, the different vaccine storage compartments do not affect each other, when only one or a few vaccines need to be taken out, only one vaccine storage compartment needs to be opened, at this time, other vaccine storage compartments remain closed, the internal temperature of the compartment is not affected, and the influence of the external temperature on other vaccines in the device during the process of taking out the vaccines is greatly reduced.

[0014] 2. In this solution, the lifting door on the box is controlled by an automatic opening and closing component, and the automatic opening and closing component is in contact with the cover door. The cover door is connected to the motor and can be opened or closed by the motor. The motor control is efficient and precise, which reduces the time required for manual opening, thereby reducing the time for external air to circulate between the internal gas of the device; when the cover door is opened, the cover door triggers the automatic opening and closing component to synchronously control the lifting door to open, which is convenient for quick and easy placement of vaccines, greatly reducing the time the cover door is open, that is, reducing the time the outside air affects the temperature in the warehouse; when the cover door is closed, the lifting door is also closed, which can better maintain the temperature and environment in the storage warehouse and reduce the impact of external temperature on the activity of the vaccine.

[0015] 3. In this solution, a carrying component is installed on the box cover to facilitate users to carry the storage device, meeting the needs of animal husbandry and veterinary medicine in different places, such as transferring it to different areas within a farm or between different farms.

[0016] Furthermore, the vaccine placement components all include inclined slide rails, and a number of sliders are slidably connected to the slide rails, and the sliders are provided with vaccine placement grooves.

[0017] Beneficial effects: The slider slides smoothly on the slide rail. When part of the vaccine needs to be taken, the slider containing the vaccine can be easily slid out, making it easy to quickly take out the required vaccine. The design of the vaccine placement slot can fix the vaccine well to prevent the vaccine from shaking or colliding when the storage device is moved or vibrated, thereby reducing the breakage of the vaccine bottle or damage to the vaccine, and effectively protecting the integrity and effectiveness of the vaccine.

[0018] Furthermore, a support plate is fixedly connected to the inside of the refrigeration warehouse, a refrigerator is installed on the top of the support plate, the refrigerator is connected to the controller signal, and a number of cold air pipes corresponding to the number of vaccine storage bins are installed along the circumference of the refrigeration warehouse wall, and the vaccine storage bins are connected to the refrigeration warehouse through the corresponding cold air pipes.

[0019] Beneficial effects: The refrigerator is installed on the support plate and can provide a stable cold source for the refrigeration warehouse. The cold air ducts are distributed circumferentially along the refrigeration warehouse wall and are connected to the vaccine storage warehouses one by one. The cold air generated by the refrigerator can be evenly and efficiently delivered to each vaccine storage warehouse, ensuring that the temperature in each vaccine storage warehouse is balanced, avoiding local overheating or overcooling, and helping to ensure the quality and effectiveness of the vaccine.

[0020] Furthermore, a second motor is installed in the top compartment, the bottom of the second motor body is fixedly connected to the top of the top plate, the output shaft of the second motor is fixedly connected to the bottom wall of the box cover, and the second motor is connected to the controller signal.

[0021] Beneficial effect: through the controller controls the operation of the second motor, can accurately control the rotation angle of the box cover, to ensure that the cover door rotates to the corresponding position of the lifting door, and then facilitates the taking of vaccines.

[0022] Further, the top plate is provided with a plurality of through holes.

[0023] Beneficial effect: the through holes can make the cold air generated by the refrigeration bin better circulate between the storage bin and the top bin of the box body, help maintain the uniformity of the temperature inside the entire box body, ensure that the vaccines are stored in a suitable low-temperature environment, and at the same time avoid the temperature of the second motor being too high during operation affecting the performance of the equipment.

[0024] Further, the automatic opening and closing assembly each includes a fulcrum fixedly connected to a position of the box body away from the lifting door, a telescopic rod sleeved on the fulcrum, the telescopic rod being rotatably connected to the corresponding fulcrum, one end of the telescopic rod extending into the taking outlet and being in contact with the cover door, and the other end of the telescopic rod being hingedly connected to the upper end of the lifting door; the length from the top of the cover door to the output shaft of the first motor is equal to the length of the telescopic rod extending into the taking outlet.

[0025] The box cover is provided with a rotating groove on the inner side of the cover door, which is in sliding fit with the telescopic rod, and the rotating groove allows the telescopic rod to rotate in the box cover.

[0026] Beneficial effect: through the connection of the cover door and the telescopic rod, when the cover door rotates under the drive of the first motor, the telescopic rod will drive the lifting door to automatically open or close under the action of the fulcrum; the distance from the top of the cover door to the output shaft of the first motor is equal to the distance from the end of the telescopic rod close to the cover door to the fulcrum, and this equal distance design can ensure that the opening and closing angles of the cover door and the lifting door have a certain proportional relationship, thereby achieving precise control, and whether opening or closing, the actions of the lifting door and the cover door are coordinated and consistent, ensuring that the opening size of the vaccine storage bin is appropriate, which facilitates the taking of vaccines and ensures good sealing when closed.

[0027] Further, a temperature sensor is installed at the bottom of the taking outlet, and a pressure sensor is installed at the middle of the upper end of the cover door, and the temperature sensor and the pressure sensor are signal-connected to the controller.

[0028] Beneficial effect: the temperature sensor can monitor the temperature near the taking outlet in real time, that is, the temperature of the vaccine storage environment, and once the temperature fluctuates abnormally and exceeds the suitable temperature range for vaccine storage, it will immediately transmit the temperature information to the controller, and the controller can accurately control the operation of the refrigeration system according to the information from the temperature sensor; the pressure sensor ensures that the cover door can be rotated to contact the corresponding telescopic rod, facilitating the controller to adjust the rotation angle of the box cover.

[0029] Further, a display screen is installed at the middle of the top surface of the box cover, and the display screen is signal-connected to the temperature sensor.

[0030] Beneficial effect: the display screen can display the temperature of the vaccine storage environment monitored by the temperature sensor in real time, so that the staff can intuitively and conveniently obtain the current temperature information without the aid of other equipment or entering the box body, so as to timely find the temperature abnormality.

[0031] Further, the box body is provided with a collection opening corresponding to the position of the recycling bin, and a bin door corresponding to the position of the collection opening is hinged to the box body.

[0032] Beneficial effect: the independent collection opening and bin door design enables the waste to directly enter the recycling bin, avoiding the random placement of waste in the box body or contact with other objects such as vaccines, effectively preventing cross contamination and ensuring the hygiene and safety of the vaccine storage environment.

[0033] Further, the carrying assembly comprises a shoulder strap, and a fixing buckle is rotatably connected to each end of the shoulder strap and fixedly connected to the two sides of the box cover.

[0034] Beneficial effect: the shoulder strap design allows the user to carry the vaccine refrigerator on the body, freeing the hands and facilitating carrying during walking, transportation, etc.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0043] The following is further described in detail through specific implementation methods:

[0044] Example 1:

[0045] As attached Figures 1-3 As shown: A portable storage device for livestock and veterinary vaccines, including a box body 4 and a box cover 1. The box body 4 is cylindrical. The box cover 1 is sleeved on the upper part of the box body 4 and is rotatably connected to the box body 4. The diameter of the box cover 1 is larger than the diameter of the box body 4. In order to facilitate carrying the device, a carrying component is installed on the box cover 1. The carrying component includes a strap 3. Both ends of the strap 3 are rotatably connected to fixed buckles 31. The fixed buckles 31 are respectively fixedly connected to both sides of the box cover 1;

[0046] The vaccine needs to be taken out after it is carried to the destination. If the cover door 2 is placed on the top, the external air has a greater effect on the overall temperature in the device when the cover door 2 is opened. If the opening range is reduced, it is inconvenient to take out the vaccine. Therefore, the box cover 1 is provided with a taking-out port 100 on one side. Since the vaccine is vertically placed, the vaccine bottle can be taken out through a smaller space from the side opening. The first motor 6 is installed on the side of the box cover 1 close to the taking-out port 100. The model of the first motor 6 is preferably SG90 micro steering engine. The output shaft of the first motor 6 is fixedly connected with the cover door 2. The first motor 6 is signal connected with the controller 102. The model of the controller 102 is preferably STM32F103C8T6. The controller 102 is installed on the top surface of the box cover 1. The taking-out port 100 and the cover door 2 are arranged on the side of the box cover 1. At the same time, the first motor 102 controls the opening and closing of the cover door 2. The opening and closing of the cover door 2 can be quickly and accurately controlled, the opening time of the cover door 2 is reduced, and the time of the external air and the internal gas flowing is reduced, that is, the influence of the external temperature on the overall temperature in the device is reduced.

[0047] Considering that the waste bottles will be generated after the injection of the vaccine is completed, and the medical waste such as the waste bottles may pollute the environment, and thus need to be collected and treated, in order to facilitate the separation of the box body 4 to form a space for collecting the waste bottles, the top plate 16 and the bottom plate 22 are fixedly connected in the box body 4 from top to bottom. The top plate 16 and the bottom plate 22 separate the box body 4 into a top bin 41, a storage bin and a recycling bin 43 from top to bottom. The box body 4 is divided into different compartments, so as to enhance the practicability of the device.

[0048] Since the vaccine storage requires a specific temperature environment, the inside of the storage bin is provided with a refrigeration bin 14, which provides a low-temperature environment for the vaccine. If all the vaccines are stored in the same space, all the vaccines in the device will be affected by the external temperature when the cover door 2 is opened. In order to reduce the influence of external air on the overall temperature in the device, a plurality of partitions 15 are fixedly connected to the inner wall of the storage bin along the circumference thereof. The top of the refrigeration bin 14 and the partitions 15 are fixedly connected to the bottom of the top plate 16, and the bottom of the refrigeration bin 14 and the partitions 15 are fixedly connected to the top of the bottom plate 22. The other end of the partitions 15 is fixedly connected to the outer wall of the refrigeration bin 14. The partitions 15 cooperate with the refrigeration bin 14 to divide the storage bin into a plurality of vaccine storage bins 42, which do not affect each other. When only part or a single vaccine needs to be taken, only the corresponding vaccine storage bin 42 needs to be opened, so that the remaining vaccines placed in other vaccine storage bins 42 are not affected by the external air. The inside of the refrigeration bin 14 is fixedly connected with a support plate 19, and the top surface of the support plate 19 is provided with a refrigeration device 18. The model of the refrigeration device 18 is preferably TEC1-12706. The refrigeration device 18 is signal connected with the controller 102. Since the refrigeration device 18 generates cold air in the refrigeration bin 14 and cannot enter the different vaccine storage bins 42, a plurality of cold air pipes 20 corresponding to the number of vaccine storage bins 42 are installed on the wall of the refrigeration bin 14 along the circumference thereof. The vaccine storage bins 42 are in communication with the refrigeration bin 14 through the corresponding cold air pipes 20. The cold air enters the corresponding vaccine storage bins 42 through the cold air pipes 20 to meet the temperature requirements of vaccine storage. If the vaccines are randomly placed in the vaccine storage bins 42, the vaccines will be broken due to collision during the movement of the device. In order to reduce this situation, the vaccine storage bins 42 are all provided with vaccine placing assemblies for placing vaccines. The vaccine placing assemblies all include inclined slide rails 10, and a plurality of sliding blocks 12 are slidingly connected to the slide rails 10. Vaccine placing grooves 13 are formed in the sliding blocks 12. The vaccines are placed in different vaccine placing grooves 13 separately. The vaccine placing grooves 13 are located on the corresponding sliding blocks 12, which can reduce the collision between the vaccines during the movement. Further, sponge buffer layers are arranged between the adjacent sliding blocks 12. Even if the sliding blocks 12 collide with each other, the sponge buffer layers can greatly absorb the collision force, greatly reducing the impact of the collision on the vaccines. If there is only one opening on the box body 4, the vaccines in the remaining vaccine storage bins 42 cannot be taken out. Therefore, each vaccine storage bin 42 needs a corresponding opening. Therefore, a plurality of lifting rails 21 corresponding to the vaccine storage bins 42 are formed on the box body 4. The lifting rails 21 are slidingly connected with lifting doors 11. Therefore, the different vaccine storage bins 42 do not affect each other. When any lifting door 11 is opened, the remaining vaccine storage bins 42 are not affected.

[0049] Although the influence of external air on the remaining vaccine storage bin 42 is reduced, two doors need to be opened each time the vaccine is taken out, which is cumbersome and increases the circulation time of external air and the internal air of the vaccine storage bin 42, thereby affecting the overall temperature in the vaccine storage bin 42. In order to reduce the consequences of this influence, the lifting door 11 is hinged with an automatic opening and closing assembly for automatically opening or closing the lifting door 11. The automatic opening and closing assembly includes a fulcrum 9, which is fixedly connected to the position of the box body 4 away from the lifting door 11. A telescopic rod 8 is sleeved on the fulcrum 9, and the telescopic rod 8 is rotatably connected to the corresponding fulcrum 9. One end of the telescopic rod 8 extends into the take-out port 100 and contacts the cover door 2. The other end of the telescopic rod 8 is hinged to the upper end of the lifting door 11. The length from the top of the cover door 2 to the output shaft of the first motor 6 is equal to the length of the telescopic rod 8 extending into the take-out port 100. Therefore, when the cover door 2 is opened, the top end of the cover door 2 will press down the telescopic rod 8. The telescopic rod 8 acts as a lever to lift the lifting door 11 through the fulcrum 9. When the cover door 2 is closed, the lifting door 11 will be lowered synchronously. Since part of the telescopic rod 8 is located outside the box body 4, it will affect the rotation of the box cover 1. Therefore, a rotating groove 7 is opened on the box cover 1, which is located on the inner side of the cover door 2 and is in sliding fit with the telescopic rod 8. Thus, the rotating groove 7 enables the telescopic rod 8 to rotate in the box cover 1. Since the lifting door 11 is opened or closed synchronously when the cover door 2 is opened or closed, the influence of external air on the overall temperature in the vaccine storage bin 42 when the cover door 2 is opened is greatly reduced, and the activity of the remaining vaccines is ensured as much as possible.

[0050] The specific implementation process is as follows: when the veterinarian needs to go out for vaccination, the device can be carried to the destination by the carrying strap 3. When the vaccine needs to be taken out, the box cover 1 is rotated to make the cover door 2 correspond to the telescopic rod 8 outside the corresponding vaccine storage bin 42. Then the first motor 6 is turned on to open the cover door 2. When the cover door 2 rotates, the outer end of the telescopic rod 8 is pressed down. The telescopic rod 8 acts as a lever to lift the inner end through the fulcrum 9, that is, the corresponding lifting door 11 is lifted synchronously. Since the lifting track 21 limits the movement track of the lifting door 11, the lifting door 11 rises along the lifting track 21, that is, the corresponding lifting door 11 is lifted when the cover door 2 is opened. Since the sliding rail 10 is inclinedly arranged, after the lifting door 11 is opened, the sliding block 12 in the corresponding vaccine storage bin 42 slides out along the sliding rail 10 with the vaccine. Since different vaccine storage bins 42 do not affect each other, when a vaccine storage bin 42 is opened alone, the temperature in the remaining vaccine storage bins 42 is not affected. After the vaccine is taken out, the cover door 2 is immediately closed, and the lifting door 11 is lowered and closed synchronously, reducing the circulation time of external air and the internal air of the vaccine storage bin 42, that is, reducing the influence of external temperature on the temperature in the vaccine storage bin 42, and overall reducing the influence of external temperature on the overall temperature in the device when part of the vaccine is taken out. Therefore, the activity of the remaining vaccines can be better ensured without being affected.

[0051] Temperature control effect experiment process

[0052] I. Experimental background and objectives

[0053] Vaccines are sensitive to storage temperature (usually 2-8℃), and the traditional single-bin vaccine box requires the whole door to be opened when taking out the vaccine, which leads to large overall temperature fluctuations (more than 5℃), affecting the activity of unused vaccines. This experiment aims to verify the temperature stability of the self-developed "multi-bin separation + synchronous door opening and closing" portable vaccine storage device (hereinafter referred to as "experimental group") in the partial vaccine taking scenario, focusing on testing:

[0054] 1. The temperature fluctuation difference between the target bin and the non-target bin when taking out the vaccine;

[0055] 2. The time for the bin temperature to recover to the set value after opening the door;

[0056] 3. The temperature control effect comparison advantage with the control group.

[0057] II. Experimental conditions and equipment

[0058] 1. Experimental objects

[0059] Experimental group: contains 4 independent vaccine storage bins (separated by partitions + refrigeration bin), synchronous door opening and closing system (cover door and lifting door linkage), TEC1-12706 refrigerators;

[0060] Control group: commercially available single-bin vaccine refrigeration box (no multi-bin separation, manual full opening of the door).

[0061] 2. Experimental environment

[0062] Environmental temperature and humidity control box: set the environmental temperature to 25℃ (simulate outdoor high temperature scenario), humidity 60%;

[0063] Initial state: the internal temperature of the experimental group and the control group is pre-cooled to 4℃ (vaccine storage standard temperature), and the experiment starts after 30 minutes of stabilization.

[0064] 3. Experimental equipment

[0065] High-precision temperature recorder (accuracy ±0.1℃): automatically records data every 5 seconds, respectively deployed in each vaccine storage bin of the experimental group (4 measuring points) and the center of the single bin of the control group (1 measuring point);

[0066] Timer: record the opening time;

[0067] Controller: used to trigger the automatic opening and closing of the cover door of the experimental group (simulate the actual vaccine taking operation);

[0068] Vaccine simulation bottle: glass material, filled with 4℃ distilled water (simulate the actual vaccine heat absorption characteristics).

[0069] 3. Experimental steps and methods

[0070] Experimental design logic

[0071] The veterinary outdoor use scenario was simulated through a "single seedling retrieval operation": only one vaccine was taken out of one vaccine storage compartment, and the temperature changes between the experimental group and the control group during the seedling retrieval process (30 seconds after opening the door) and after closing the door (within 300 seconds) were compared.

[0072] Specific experimental steps:

[0073] Step 1: Pre-experimental preparation

[0074] The experimental group and the control group were placed in an environmental temperature and humidity control box, and the refrigeration system was turned on. After the internal temperature stabilized to 4°C (fluctuation ≤ 0.5°C for 30 consecutive minutes), the refrigeration system was turned off (to simulate that the set temperature had been reached during transportation, relying only on the thermal insulation performance).

[0075] In the experimental group, 5 vaccine simulation bottles were placed in each vaccine storage compartment (a total of 20 bottles), and in the control group, 20 vaccine simulation bottles were placed in a single compartment (without partitions).

[0076] Step 2: Temperature control test of experimental group (seeding from target warehouse)

[0077] Select the target warehouse: Randomly select one vaccine storage warehouse in the experimental group (marked as "Warehouse A"), and mark the remaining three warehouses as "Warehouse B, C, D".

[0078] Trigger the seedling removal operation:

[0079] Turn the box cover so that the cover door is aligned with the corresponding telescopic rod of bin A;

[0080] The controller triggers the first motor (SG90 micro servo) to open the cover door (synchronously opening the lift door of compartment A);

[0081] Keep the cover door open for 30 seconds (simulating the time for removing seedlings), and then close the cover door (close the lifting door synchronously).

[0082] Data Records:

[0083] Record the temperature changes of chamber A before the door is opened (-30 seconds to 0 seconds), during the door opening (0 seconds to 30 seconds), and after the door is closed (30 seconds to 330 seconds);

[0084] Simultaneously record the temperature changes of bins B, C, and D (to verify whether non-target bins are affected).

[0085] Step 3: Temperature control test of the control group (seedlings from a single warehouse)

[0086] Trigger the seedling removal operation: manually open the control group door, keep it open for 30 seconds (simulating the seedling removal time), and then close the door.

[0087] Data record:

[0088] The temperature change of the single-warehouse record before the door is opened (-30 seconds to 0 seconds), during the opening of the door (0 seconds to 30 seconds), and after the door is closed (30 seconds to 330 seconds).

[0089] Step 4: Repeat the experiment and calibrate the data

[0090] Each group of experiments is repeated 5 times (to avoid accidental errors), and the average value is taken as the final data.

[0098] 4. Comparative analysis

[0099] Target warehouse temperature fluctuation: the experimental group only 0.7℃ (4.1→4.8℃), the control group reached 3.5℃ (4.0→7.5℃);

[0100] Non-target warehouse influence: the experimental group has no significant fluctuation (≤0.1℃), and the control group's single-warehouse overall temperature rises by 3.5℃;

[0101] Temperature recovery time: the experimental group recovers to 4.2℃ (close to the set value) 30 seconds after the door is closed, while the control group is still 5.2℃ 300 seconds after the door is closed (the risk of exceeding the upper limit of vaccine storage 8℃ is low, but far from meeting the standard).

[0102] Five, experimental conclusion

[0103] This experiment verifies the temperature control advantages of the experimental group in the partial seedling taking scenario, and the core conclusions are as follows:

[0104] 1. Multiple-warehouse separation + synchronous door opening and closing design significantly reduces temperature fluctuation

[0105] The experimental group divides the storage warehouse into independent vaccine storage warehouses by the partition, and cooperates with the "synchronous opening and closing" function of the cover door and the lifting door, only the target warehouse is in contact with the external air (the opening area is ≤1 / 4 of the control group), and the non-target warehouse is completely closed, avoiding the defect of the control group "whole warehouse door opening leading to overall temperature rise".

[0106] 2. Precise temperature control to ensure vaccine activity

[0107] The temperature of the target compartment in the experimental group only increased by 0.7℃ (maximum 4.8℃) within 30 seconds after opening, still within the safe storage range (2-8℃) for vaccines; the temperature of the non-target compartment did not change (≤4.1℃), and the activity of the unused vaccine was not affected. In the control group, the temperature of a single compartment increased by 3.5℃ (maximum 7.5℃) within 30 seconds after opening, although it did not exceed the upper limit, the temperature fluctuation was large, and it did not recover to 4℃ even 300 seconds after closing. Long-term use may accelerate the expiration of the vaccine.

[0108] 3. Core advantages of technical innovation compared to traditional solutions

[0109] Comparative item Experimental group Control group Temperature fluctuation at the time of seedling taking Target compartment ≤0.7°C, no impact on non-target compartment Overall fluctuation of single compartment ≥3.5°C Temperature recovery time Recovery to the set value within 30s after door closing No recovery to the safe temperature within 300s Vaccine active protection No impact on the temperature fluctuation without using vaccine All vaccines are affected by high temperature fluctuation

[0110] Summary: The experimental group solves the core pain point of traditional vaccine boxes, which have large temperature fluctuations when taking vaccines, by separating multiple compartments, synchronously opening and closing the doors, and precise refrigeration design. In the outdoor vaccine inoculation scene of livestock and veterinary medicine, it can more reliably ensure the activity of unused vaccines, and has significant technical advantages.

[0111] Example 2:

[0112] As shown in the accompanying drawings, Figures 1-3 The difference from Example 1 is that since the box body 4 is located inside the box cover 1, the specific situation of the box body 4 cannot be observed when the box cover 1 is rotated, and manually rotating the box cover 1 cannot accurately align the cover door 2 with the corresponding lifting door 11. Therefore, a second motor 17 is installed in the top compartment 41, and the model of the second motor 17 is preferably MG996R. The bottom of the second motor 17 body is fixedly connected to the top of the top plate 16, and the output shaft of the second motor 17 is fixedly connected to the inner bottom wall of the box cover 1. The second motor 17 is signal connected with the controller 102, and the rotation of the second motor 17 is controlled by the controller 102, so that the box cover 1 can be accurately rotated to the specified position. Compared with manually rotating the box cover 1, the control by the second motor 17 is more accurate and faster, improving the work efficiency. Since the second motor 17 generates heat during operation, and the second motor 17 is in a closed environment which may cause the temperature to be too high to affect the operation of the equipment, a plurality of through holes 161 are opened on the top plate 16, so that the cold air in the vaccine storage compartment 42 can enter the top compartment 41 to cool the second motor 17 and prevent it from overheating;

[0113] When the cover door 2 is opened, external air will enter the corresponding vaccine storage bin 42, thereby affecting the overall temperature in the bin. In order to timely understand the temperature change, a temperature sensor 103 is installed at the bottom of the taking-out port 100. The model of the temperature sensor 103 is preferably DS18B20. The output end of the temperature sensor 103 is signal connected with the input end of the controller 102. The temperature sensor 103 collects the temperature information of the taking-out port 100 in real time and transmits it to the controller 102, so that the controller 102 can timely adjust the refrigerator 18 to adjust the temperature to the required temperature range for vaccine storage. When the temperature is too high, the controller 102 receives the signal transmitted by the temperature sensor 103, and then controls the refrigerator 18 to reduce the temperature, so as to ensure that the internal temperature of the device is within the required temperature range for vaccine storage. However, during the temperature change process, the carrier cannot intuitively understand the temperature change, so a display screen 101 is installed in the middle of the top surface of the box cover 1. The model of the display screen 101 is preferably OLED 0.96 inch I2C interface module. The display screen 101 is signal connected with the temperature sensor 103. The temperature sensor 103 transmits the collected temperature information to the controller 102. The controller 102 transmits the processed information to the display screen 101, so that the carrier can observe the temperature change in real time through the display screen 101, so as to make timely adjustment.

[0114] Since it is impossible to judge whether the cover door 2 is accurately rotated to the accurate position during the rotation process, a pressure sensor is installed in the middle of the upper end of the cover door 2. The model of the pressure sensor is preferably BMP280. The pressure sensor is signal connected with the controller 102. When the telescopic rod 8 contacts the pressure sensor, it indicates that the cover door 2 reaches the accurate position. At this time, the pressure sensor transmits information to the controller 102, so that the controller 102 can control the second motor 17 to rotate or stop, that is, the controller 102 accurately controls the rotation of the box cover 1, so that the cover door 2 is opened at the accurate position. Compared with the manual control of the rotation of the box cover 1, which may be adjusted several times to ensure that the cover door 2 contacts the telescopic rod 8, the accurate control of the rotation of the box cover 1 by the controller 102 greatly improves the work efficiency.

[0115] The specific implementation process is as follows: when the vaccine needs to be taken out, the parameters of the controller 102 are adjusted in advance, the second motor 17 is controlled to rotate by the controller 102 to drive the box cover 1 to rotate, when the controller 102 receives the signal transmitted by the pressure sensor, it indicates that the telescopic rod 8 is in contact with the pressure sensor, that is, the cover door 2 reaches the position corresponding to the vaccine storage bin 42, the controller 102 controls the second motor 17 to stop, and then the controller 102 controls the first motor 6 to rotate to open the cover door 2, and the lifting door 11 is opened at the same time, and the vaccine taking work is carried out. In this process, the temperature sensor 103 monitors the temperature of the outlet 100 in real time, and transmits the data information to the display screen 101 and the controller 102. The carrier can intuitively understand the temperature change in the device during the vaccine taking process through the display screen 101, and the controller 102 can adjust the overall temperature in the device by presetting the parameters of the refrigerator 18, so as to reduce the influence of external air on the overall temperature in the device as much as possible during the vaccine taking process.

[0116] Example 3:

[0117] As shown in the accompanying drawings, Figure 1 , Figure 2 The difference from example 2 is that the recycling bin 43 is used to collect waste such as waste vaccine bottles, and the box body 4 is provided with a collection opening 51 corresponding to the position of the recycling bin 43. During the movement of the device, the waste may fall out of the opening. In order to avoid this situation, the box body 4 is hinged with a bin door 5 corresponding to the position of the collection opening 51. The bin door 5 is closed to avoid the waste falling off during the movement.

[0118] The specific implementation process is as follows: after the vaccination is completed, the bin door 5 can be opened, and the used vaccine bottles or medical waste can be put into the recycling bin 43 for collection, and then the bin door 5 is closed to avoid the waste falling off during the movement. The waste is collected and treated in the corresponding place to reduce the pollution of the waste to the environment.
