Abstract
Description
Technical Field
[0001] This utility model relates to the field of special storage technology, specifically a multifunctional vaccine transport and storage box. Background Technology
[0002] As a core biological product in the field of biological research, vaccines play an irreplaceable role in infectious disease control, exploration of immune mechanisms, and development of novel therapies. Their complex molecular structures and extreme temperature sensitivity necessitate storage and transportation within a strictly controlled temperature environment of 2-8°C to maintain potency and stability. In laboratory development, field sampling, or inter-institutional collaborations, vaccines undergo multiple handling and environmental changes, placing high demands on the reliability of storage equipment. Efficient temperature control systems not only ensure the accuracy of research data but also support the implementation of global biosafety initiatives, driving scientific progress.
[0003] Currently, existing vaccine transport and storage boxes have significant deficiencies in the uniformity of cold air distribution. Due to the lack of proper guidance in the cold air circulation path, cold air accumulates in areas near the cooling source, while areas far from the cooling source receive insufficient cold air, resulting in a significant temperature gradient within the box. This uneven cold air distribution places vaccines in different temperature environments at different storage locations. Some vaccines may lose their activity due to prolonged exposure to suboptimal temperature ranges, making it difficult to ensure that all vaccines maintain a stable quality state during transport. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional vaccine transport and storage box.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A multifunctional vaccine transport and storage box, including
[0007] The barrel-shaped box has a refrigeration chamber protruding from its side and communicating with its internal cavity.
[0008] A storage container for storing vaccines is rotatably mounted inside the box, and a closed, interconnected flow cavity is formed between its outer wall and the inner wall of the box.
[0009] Both the storage component and the exterior of the refrigeration chamber are equipped with bevel gears, and the two bevel gears mesh with each other. A fan blade is coaxially fixed to the side of the bevel gear in the refrigeration chamber.
[0010] The rotation of the storage component is driven by the meshing transmission of a bevel gear to rotate the fan blades, and the rotation direction of the fan blades is adapted to the annular extension direction of the flow cavity.
[0011] The annular structure of the flow cavity is configured to guide the cold air to circulate along the annular path, and the vaccine storage positions of the storage device are distributed along the annular path of the flow cavity.
[0012] Preferably, the two bevel gears are of different sizes, with the diameter of the bevel gear coaxially fixed to the storage component being larger than the diameter of the bevel gear coaxially fixed to the fan blade.
[0013] Preferably, the storage unit includes multiple vaccine storage units that are evenly distributed circumferentially. Each vaccine storage unit includes a detachable insulated box with a cushioning and shock-absorbing structure inside, which is made of elastic sponge or silicone pad.
[0014] Preferably, the cross-section of the flow cavity has a tapered flow channel structure, with the width on the side closer to the cooling chamber being greater than that on the side farther from the cooling chamber.
[0015] Preferably, the cooling chamber is provided with a semiconductor cooling chip, the cold end of which faces the flow cavity, and the hot end is connected to a heat dissipation fin.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention utilizes a synergistic design of an annular flow cavity, rotating storage unit, and fan-driven mechanism. Cold air circulates along an annular path, and the vaccine storage unit rotates evenly through various areas of the cold air circulation path. Simultaneously, the tapered flow channel structure accelerates the flow of cold air, prevents cold air accumulation near the cooling source, effectively eliminates temperature gradients within the chamber, ensures all vaccines are in a consistent low-temperature environment, and guarantees vaccine activity and stability.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0025] Example
[0026] like Figure 1 , Figure 3 As shown, a multifunctional vaccine transport and storage box includes a barrel-shaped box 1. The surface of the box 1 is provided with a matching sealing cover (not shown in the figure) to prevent cold air from escaping. A cooling chamber 2 is provided on the side of the barrel-shaped box 1 and communicates with its inner cavity. This provides a necessary channel for cold air to enter the flow chamber 4 inside the box 1 from the cooling chamber 2, ensuring that the cold air generated by the cooling can smoothly enter the circulation system and provide a continuous low temperature environment for the vaccine storage area.
[0027] The cooling chamber 2 is equipped with a semiconductor cooling chip 10. The semiconductor cooling chip 10 works based on the Peltier effect. When direct current passes through a coupler composed of two different semiconductor materials connected in series, heat can be absorbed and released at the two ends of the coupler respectively, thereby achieving a cooling effect. The cold end of the semiconductor cooling chip 10 faces the flow chamber 4. The purpose of this design is to allow the cold energy generated at the cold end to be directly transferred to the flow chamber 4, cooling the air in the flow chamber 4 and forming circulating cold air, which directly affects the temperature maintenance of the vaccine storage area.
[0028] The hot end of the thermoelectric cooler 10 is connected to the heat sink 11. During the cooling process, the hot end will continuously generate a large amount of heat. If this heat cannot be dissipated in time, it will cause the temperature of the thermoelectric cooler 10 to rise, which will seriously affect its cooling efficiency and may even burn out the component. The heat sink 11 is usually made of a metal material with excellent thermal conductivity. By increasing the contact area with the air, it can quickly conduct the heat generated by the hot end of the thermoelectric cooler 10 to the external environment, ensuring that the thermoelectric cooler 10 can continuously and stably play a cooling role, thereby providing reliable cold source support for the low temperature environment inside the vaccine transport and storage box.
[0029] Preferred, such as Figure 1-4As shown, the storage unit 3, which can store vaccines, is rotated inside the box 1. A servo motor is installed at the bottom of the box 1. The output end of the servo motor is connected to the storage unit 3 to drive the storage unit 3 to rotate at a constant speed, so that the vaccines are brought close to the cooling chamber 2 and close to the cold air.
[0030] The storage unit 3 includes multiple vaccine storage units 7, which are evenly distributed circumferentially. This layout is adapted to the annular path of the flow cavity 4, so that each vaccine storage unit 7 can pass through each area of the flow cavity 4 in sequence when the storage unit 3 rotates, and evenly contact the circulating cold air, avoiding the problem of uneven temperature caused by fixed position, and providing a consistent low temperature environment for the vaccine from the perspective of spatial distribution.
[0031] Each vaccine storage unit 7 includes a removable insulated box 8. The insulated box 8 itself has a certain heat preservation performance, which can form an additional temperature barrier for the internal vaccine on the basis of the overall low temperature environment of the flow chamber 4, further reducing the impact of external heat penetration on the vaccine.
[0032] The insulated box 8 is equipped with a cushioning and shock-absorbing structure 9, which is an important guarantee to protect the vaccine from mechanical damage. The cushioning and shock-absorbing structure 9 is made of elastic sponge or silicone pad. Both of these materials have excellent elastic deformation capacity and cushioning performance. When encountering bumps, vibrations or collisions during transportation, the elastic sponge or silicone pad will absorb and disperse the external impact force through its own compression and rebound, minimizing the mechanical stress on the vaccine and preventing the vaccine from becoming ineffective due to the vaccine container breaking due to vibration. In addition, the close fit between the elastic material and the vaccine container can also reduce the shaking space of the vaccine in the insulated box 8, further enhancing the fixation effect and ensuring the stability of the vaccine in complex transportation environments.
[0033] A closed, interconnected flow cavity 4 is formed between the outer wall of the storage component 3 and the inner wall of the box 1. The annular structure of the flow cavity 4 is designed to guide the cold air to circulate along the annular path. The vaccine storage positions of the storage component 3 are distributed along the annular path of the flow cavity 4. The flow cavity 4 is the core channel for the circulation of cold air in the box 1. Its design directly affects the distribution efficiency and uniformity of the cold air. The flow cavity 4 adopts a closed structure, which can ensure that the cold air forms a complete circulation path in the box, avoid cold air leakage or disorderly diffusion, thereby maximizing the use of the cold energy generated by the refrigeration source and maintaining the stability of the low temperature environment in the box.
[0034] The cross-section of the flow cavity 4 has a gradually narrowing flow channel structure, with its width on the side closer to the cooling chamber 2 being greater than that on the side farther from the cooling chamber 2.
[0035] When the cold air generated by the semiconductor cooling chip 10 enters the flow chamber 4 from the cooling chamber 2, it first enters the wider area. At this time, the cold air has enough space to diffuse initially in this area, avoiding a sudden drop in local temperature due to excessive concentration when it first enters.
[0036] As the cold air flows along the flow cavity 4 away from the cooling chamber 2, the width of the flow channel gradually decreases. According to the continuity equation in fluid mechanics, under the condition of constant flow rate, the decrease in the cross-sectional area of the flow channel will gradually increase the flow speed of the cold air. This acceleration effect can effectively prevent the cold air from slowing down and accumulating due to resistance during the flow process, ensuring that the cold air can quickly and smoothly reach all corners of the flow cavity 4, including areas away from the cooling chamber 2.
[0037] The tapered structure can also guide the cold air to form an orderly spiral or ring-shaped flow trajectory, which, in conjunction with the airflow direction driven by the fan blades 6, further enhances the stability and coverage of the cold air circulation and reduces airflow turbulence or dead zones caused by unreasonable flow channel structure.
[0038] Both the storage unit 3 and the exterior of the refrigeration chamber 2 are equipped with bevel gears 5, which mesh with each other. A fan blade 6 is coaxially fixed on the side of the bevel gear 5 in the refrigeration chamber 2. The rotation of the storage unit 3 is driven by the meshing transmission of the bevel gears 5 to rotate the fan blade 6. The rotation direction of the fan blade 6 is adapted to the annular extension direction of the flow chamber 4. Through the meshing relationship, the fan blade 6 receives the power from the bevel gear 5 on the side of the storage unit 3. The servo motor drives the storage unit 3 to rotate, which in turn drives the corresponding bevel gear 5 to rotate, which in turn drives the other bevel gear 5 to rotate, which in turn drives the fan blade 6 to rotate, thus accelerating the flow of cold air in the housing 1.
[0039] The two bevel gears 5 are of different sizes. The diameter of the bevel gear 5 that is coaxially fixed with the storage unit 3 is larger than the diameter of the bevel gear 5 that is coaxially fixed with the fan blade 6. According to the gear transmission principle, the smaller diameter gear will get a higher rotation speed. The rotation speed of the fan blade 6 will be much higher than the rotation speed of the storage unit 3. The storage unit 3 only needs to rotate at a slower speed to ensure that the vaccine storage unit 7 passes evenly through all areas of the flow chamber 4, while the fan blade 6 needs a higher rotation speed to generate enough wind to drive the cold air to circulate quickly in the flow chamber 4. The compatibility of the rotation speeds of the two ensures the dual requirements of uniform cooling of the vaccine and efficient flow of cold air.
[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
