Description

Technical Field

[0001] This utility model relates to the field of vaccine cold chain storage technology, specifically to an intelligent vaccine management refrigerator. Background Technology

[0002] Intelligent vaccine management refrigerators are devices that incorporate cold chain technology to ensure the safe storage of each vaccine and maintain its efficacy. These devices typically monitor temperature in real time to ensure that vaccines are not affected by temperature fluctuations during storage, thus preserving their potency. However, in practical applications, these management refrigerators may also encounter the problem of unsold vaccines.

[0003] Specifically, when new vaccines are replenished to the vaccine management cabinet, if the new vaccines are placed at the front of the cabinet, vaccines at the back may be forgotten due to prolonged unuse. This can lead to expired or ineffective vaccines, severely impacting their efficiency and safety. To address this issue, some improvements have been proposed, such as establishing a fixed vaccine storage strategy and prioritizing vaccines nearing their expiration date. However, these methods typically require frequent manual adjustments by staff, increasing operational complexity and the risk of errors. Furthermore, the prolonged opening of the cabinet door during these adjustments causes cold air leakage and a rapid temperature increase within the cabinet. For example, the temperature can rapidly rise from the standard refrigeration range of 2-8°C to above 10°C, especially for vaccines near the door. This high temperature fluctuation can damage the vaccine's biological activity, causing potency reduction or even complete ineffectiveness. It can also lead to ineffective immunization or adverse reactions after vaccination, easily resulting in the waste of large quantities of vaccines, causing direct economic losses and wasting medical resources. This severely impacts vaccine storage safety and efficiency, ultimately affecting the practicality of the vaccine management cabinet. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent vaccine management refrigerator to solve the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides an intelligent vaccine management refrigerator, including an intelligent temperature control system. A shell is installed at the upper end of the intelligent temperature control system, and a refrigeration cavity is formed inside the shell. Multiple sets of evenly distributed air outlets, matching the intelligent temperature control system, are formed on the inner wall of the shell. These air outlets are connected to the refrigeration output end of the intelligent temperature control system to evenly deliver cold air into the refrigeration cavity to maintain the low-temperature environment required for vaccine storage. The shell has a vaccine storage port and a vaccine retrieval port, with a height difference between them. A flow guiding structure matching the vaccine storage port and retrieval port is installed inside the shell. The flow guiding structure includes a spiral flow guiding groove, with its upper end connected to the vaccine storage port and its lower end connected to the vaccine retrieval port. A slider is slidably connected to the spiral flow guiding groove, and the slider has a placement groove matching the vaccine. A vaccine retrieval structure matching the vaccine retrieval port is installed on the shell.

[0007] In one or more embodiments of this utility model, the immunization structure includes a limiting block, a fifth sliding groove matching the immunization port is provided on the housing, the limiting block is slidably connected in the fifth sliding groove, a sixth sliding groove matching the fifth sliding groove is provided on the housing, and a second screw matching the sixth sliding groove is fixedly connected to the limiting block, the second screw being slidably connected up and down in the sixth sliding groove.

[0008] In one or more embodiments of this utility model, a connecting post is fixedly connected to the lower end of the limiting block, and a spring matching the connecting post is installed in the fifth sliding groove.

[0009] In one or more embodiments of this utility model, the housing is equipped with two sealing structures that respectively match the storage port and the extraction port.

[0010] In one or more embodiments of this utility model, the sealing structure includes a heat insulation plate, a first screw threadedly connected to the heat insulation plate, a knob fixedly connected to the end of the first screw away from the heat insulation plate, a first sliding groove matching the heat insulation plate and matching the storage port on the housing, and a second sliding groove matching the first screw on the housing, wherein one of the heat insulation plates is slidably connected in the first sliding groove.

[0011] In one or more embodiments of this utility model, a third sliding groove matching the heat insulation plate is provided on the housing, the third sliding groove matching the effluent port, one of the heat insulation plates being slidably connected in the third sliding groove, and a fourth sliding groove matching the third sliding groove is provided on the housing, one of the first screws being slidably connected in the fourth sliding groove.

[0012] In one or more embodiments of the present invention, the flow guiding structure further includes a discharge trough, which is detachably mounted on the housing, and one end of the discharge trough matches the lower end of the spiral flow guiding trough.

[0013] In one or more embodiments of the present invention, the flow guiding structure further includes a feed trough, which is detachably mounted on the housing, and one end of the feed trough matches the upper end of the spiral flow guiding trough.

[0014] In one or more embodiments of this utility model, the upper end of the housing is provided with an opening, and a cover that matches the opening is rotatably connected to the housing.

[0016] The beneficial effects of this utility model are as follows: by using the design of top storage and bottom retrieval, spiral guide channel and slider, a first-in-first-out logic is formed. The vaccines stored first slide to the retrieval port first, which avoids the back-end vaccines being forgotten and expired from the source. Moreover, there is no need for manual adjustment of the position, which greatly reduces the complexity of operation and the risk of error. It also reduces the problems of long-term opening of the hatch and cold leakage caused by manual operation, and further enhances the stability of temperature control.

[0017] Combining intelligent constant temperature sealing, gradient ball uniform speed sliding, and vaccine retrieval structure, it comprehensively ensures vaccine storage safety and accurate retrieval, significantly improving vaccine usage efficiency and equipment practicality;

[0018] During the process of retrieving vaccines, the opening time of the hatch is significantly shortened, further reducing temperature fluctuations caused by cold air leakage. At the same time, it avoids adverse effects such as potency reduction and damage to biological activity caused by prolonged exposure of vaccines to non-standard storage temperature zones or collisions during handling.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments. Example 1:

[0033] like Figures 1-4As shown, an embodiment of the present invention provides an intelligent vaccine management refrigerator, comprising an intelligent temperature control system 1. A housing 2 is mounted on the upper end of the intelligent temperature control system 1, with an opening at the upper end of the housing 2. A cover 201, matching the opening, is rotatably connected to the housing 2. A refrigeration chamber is formed inside the housing 2, and an air outlet 208, matching the intelligent temperature control system 1, is formed on the inner wall of the housing 2. The air outlet 208 is connected to the cooling output end of the intelligent temperature control system 1, used to uniformly deliver cold air into the refrigeration chamber to maintain the low-temperature environment required for vaccine storage. The intelligent temperature control system 1 can monitor the temperature of the inner cavity of the housing 2 and, based on the detection results, deliver cold or hot air into the interior of the housing 2 through the air pipe and the air outlet 208, keeping the temperature inside the housing 2 within a certain range to avoid excessively high or low temperatures that could cause vaccine inactivation.

[0034] like Figures 1-4 As shown, the shell 2 has a storage port and a retrieval port. The storage port is located at the top of the shell 2, and the retrieval port is located at the bottom of the shell 2, with a height difference between the storage port and the retrieval port. A flow guiding structure 3 matching the storage port and the retrieval port is installed inside the shell 2, and the flow guiding structure 3 is located inside the refrigeration cavity.

[0035] Specifically, such as Figures 1-4 As shown, the flow guiding structure 3 includes a spiral flow guiding groove 4. The upper end of the spiral flow guiding groove 4 is connected to the storage port, and the lower end of the spiral flow guiding groove 4 is connected to the extraction port. A slider 7 is slidably connected to the spiral flow guiding groove 4. A placement groove 701 matching the vaccine is opened on the slider 7. Multiple spring pieces 8 matching the placement groove 701 are fixedly connected to the slider 7. The spring pieces 8 are used to clamp the vaccine bottle.

[0036] When storing the vaccine, it is first placed in the placement slot 701 on the slider 7. Then, the slider 7 with the vaccine is inserted through the storage port and placed at the upper end of the spiral guide channel 4. The slider 7 can slide downwards along the direction set by the spiral guide channel 4 until it reaches the retrieval port. The housing 2 is equipped with a retrieval structure that matches the retrieval port. Using the retrieval structure, one vaccine can be retrieved at a time, or multiple vaccines can be retrieved.

[0037] like Figure 7 , Figure 9As shown, the immunization structure includes a limiting block 12. A fifth sliding groove 206, matching the immunization port, is provided on the housing 2. The fifth sliding groove 206 is located on the bottom wall of the immunization port. The limiting block 12 is slidably connected within the fifth sliding groove 206. A sixth sliding groove 207, matching the fifth sliding groove 206, is provided on the housing 2. A second screw 1202, matching the sixth sliding groove 207, is fixedly connected to the limiting block 12. The second screw 1202 slidably connects up and down within the sixth sliding groove 207. A connecting post 1201 is fixedly connected to the lower end of the limiting block 12. A spring 13, matching the connecting post 1201, is installed within the fifth sliding groove 206.

[0038] In the initial state, the fifth slide 206 is pushed upward by the spring 13, blocking the vaccination port and preventing the vaccine from sliding out. When it is necessary to retrieve the vaccine, the second screw 1202 is pressed down, forcing the limiting block 12 to slide downward within the fifth slide 206. When the upper end face of the limiting block 12 is equal to or lower than the inner bottom wall of the spiral guide groove 4, the slider 7 sliding within the spiral guide groove 4 loses the blocking force, and the slider 7 slides outward under the action of gravity and tilting force.

[0039] like Figures 1-9 As shown, a limiting groove 702 is provided at the bottom of the slider 7, and the limiting groove 702 opens and closes on both sides of the slider 7 in the sliding direction. With the intervention of the limiting groove 702, after the user presses down the second screw 1202 once, the slider 7 moves forward. When the user releases the second screw 1202, the spring 13 resets the limiting block 12. At this time, under the combined action of the subsequent pushing force, gravity, and tilting force of the slider 7, even if one end of the limiting block 12 contacts the bottom wall of the slider 7, the slider 7 will continue to slide in the spiral guide groove 4 until the next slider 7 slides to the position matching the limiting block 12. Under the action of the spring 13, the limiting block 12 can be locked into the limiting groove 702, restricting the slider 7 from continuing to slide, so that only one vaccine is taken with each press of the connecting column 1201.

[0040] In the above embodiments, the height difference between the storage port and the retrieval port, combined with the sliding design of the spiral guide channel 4 and the slider 7, allows the vaccines to automatically and orderly slide down the spiral guide channel 4 after storage, eliminating the need for manual lifting or sorting, thus meeting the needs of large-scale vaccine storage. Furthermore, through the coordinated design of the limiting block 12, the spring 13, and the placement slot 701, precise control of retrieving a single vaccine with a single press is achieved, ensuring accurate control of the number of vaccines retrieved and avoiding over-retrieval or mis-retrieval.

[0041] like Figures 1-10 As shown, the flow guiding structure 3 also includes a discharge trough 6 and a feed trough 5. The feed trough 5 is installed at a position that matches the housing 2 and the storage port, and matches the upper end of the spiral flow guiding trough 4. The discharge trough 6 is installed at a position that matches the housing 2 and the collection port, and matches the lower end of the spiral flow guiding trough 4.

[0042] In actual use, the slider 7 containing the vaccine is first placed into the feed trough 5, and then pushed onto the spiral guide channel 4 by pushing the slider 7. When retrieving the vaccine, the second screw 1202 is pressed, and the vaccine slides from the spiral guide channel 4 onto the discharge trough 6, thus achieving vaccine collection.

[0043] like Figure 10 As shown, if the feed trough 5 and the discharge trough 6 are on the same side, meaning they can be interchanged, the vaccine slides onto the discharge trough 6 via the slider 7. The vaccine is then removed from the slider 7, which remains in the discharge trough 6. When the discharge trough 6 is full, the positions of the feed trough 5 and the discharge trough 6 can be swapped. When storing the vaccine, the discharge trough 6, now in a different position, is installed above the housing 2 and communicates with the spiral guide channel 4. The vaccine is directly placed into the placement slot 701, and then the slider 7 is pushed from the discharge trough 6 into the spiral guide channel 4.

[0044] like Figures 1-10 As shown, the intelligent temperature control system 1 is equipped with a mounting plate 14 that matches the inlet and outlet ports. The feed trough 5 and the outlet trough 6 are detachably mounted on the mounting plate 14. Multiple limiting posts 15 are fixedly connected to the lower ends of both the feed trough 5 and the outlet trough 6. The mounting plate 14 has limiting holes 1401 that match the limiting posts 15. The limiting posts 15 can be inserted into the limiting holes 1401, allowing the feed trough 5 and the outlet trough 6 to be detachably mounted on the housing 2.

[0045] In the above embodiment, the feeding trough 5 is adapted to the upper end of the vaccine storage port and the spiral guide trough 4, providing a dedicated transitional placement space for the slider 7. When pushing the slider 7 to the spiral guide trough 4, it is easier to align and the force is more stable, avoiding direct delivery that could cause vaccine collision or the slider 7 to get stuck. The discharging trough 6 connects the lower end of the spiral guide trough 4 and the vaccine retrieval port. When retrieving the vaccine, the slider 7 first slides into the discharging trough 6 before being retrieved. It can catch the sliding slider 7 and the vaccine, preventing the vaccine from accidentally falling and being damaged during the retrieval process.

[0046] In addition, when the feed trough 5 and the discharge trough 6 are on the same side and interchangeable, after the discharge trough 6, which is filled with empty sliders 7 after the virus is removed, is fully loaded, it can be directly replaced to the virus storage port position as the feed trough 5. There is no need to separately recover and transfer the empty sliders 7, realizing a closed-loop operation of virus removal, recovery of empty sliders 7, and reloading of virus, reducing the handling steps of manually taking sliders 7, and at the same time, there is no need to set up an additional storage device for empty sliders 7, saving space around the equipment.

[0047] Because the storage and retrieval ports are connected to the interior of the casing 2, and are also connected to the external environment, hot or cold air inside the casing 2 can easily leak from these ports. To solve this problem, two sealing structures 9 are installed on the casing 2, each matching the storage and retrieval ports. When the intelligent vaccine management refrigerator is not in use, the sealing structures 9 can form a barrier between the storage and retrieval ports, preventing the casing 2 from communicating with the environment.

[0048] like Figures 1-9 As shown, the sealing structure 9 includes a heat insulation plate 10, on which a first screw 11 is threadedly connected. A knob 1101 is fixedly connected to the end of the first screw 11 away from the heat insulation plate 10. A first sliding groove 202 matching the heat insulation plate 10 is provided on the housing 2, and the first sliding groove 202 matches the storage port. A second sliding groove 203 matching the first screw 11 is provided on the housing 2, and one of the heat insulation plates 10 is slidably connected in the first sliding groove 202.

[0049] There is a gap between the upper end of the spiral guide channel 4 and the feed channel 5, and the heat insulation plate 10 is located in the gap. This gap does not affect the continuous sliding of the slider 7 between the spiral guide channel 4 and the feed channel 5.

[0050] When the sealing structure 9 located at the storage port tightens the first screw 11, it can increase the friction between the insulation plate 10 and the shell 2, so that the insulation plate 10 stops sliding in the third slide groove 204.

[0051] Among them, the insulation board 10 is made of polyurethane insulation material, which can effectively block the heat exchange between the cold storage cavity and the outside. When the insulation board 10 is closed, it fits tightly with the inner wall of the slide, which greatly reduces the cold leakage rate of the storage port and the retrieval port, and avoids the temperature fluctuation of the cold storage cavity due to heat exchange.

[0052] like Figures 1-9 As shown, the housing 2 has a third sliding groove 204 that matches the insulation plate 10. The third sliding groove 204 matches the immunization port. One of the insulation plates 10 is slidably connected in the third sliding groove 204. The housing 2 also has a fourth sliding groove 205 that matches the third sliding groove 204. One of the first screws 11 is slidably connected in the fourth sliding groove 205. The insulation plate 10 in the third sliding groove 204 is positioned to match the limiting block 12. The third sliding groove 204 is located on the top wall of the immunization port. When the insulation plate 10 closes the immunization port, it presses down on the limiting block 12, causing the limiting block 12 to be located in the fifth sliding groove 206, ensuring the sealing effect of the insulation plate 10.

[0053] In the above embodiments, the beneficial effects of the intelligent vaccine management refrigerator include at least the following:

[0054] The storage and retrieval ports are equipped with sealing structures 9. When not in use, the insulation board 10 forms a physical barrier to block the airflow between the inside of the shell 2 and the outside, thereby reducing the leakage of cold and hot air from the source, avoiding the frequent start and stop of the intelligent temperature control system 1 to compensate for the temperature difference, reducing the problem of long-term opening of the hatch and leakage of cold air caused by manual operation, and further enhancing the stability of temperature control. Example 2:

[0055] Unlike Example 1, as Figures 11-12 As shown, the bottom of the spiral guide groove 4 is provided with multiple sets of evenly distributed first balls 16, and the sidewall of the spiral guide groove 4 is provided with multiple sets of evenly distributed second balls 17. The slider 7 is provided with a guide groove 703 that matches the second balls 17. Through the cooperation of the guide groove 703 and the second balls 17, the slider 7 can be stably fixed in the spiral guide groove 4, ensuring that the slider 7 will not detach from the spiral guide groove 4 during sliding. The presence of the first balls 16 and the second balls 17 can also increase the sliding speed of the slider 7 in the spiral guide groove 4.

[0056] Since the slider 7 accelerates during sliding, to prevent damage to the vaccine on the slider 7 due to excessive speed, the tilt angle of the spiral guide groove 4 can be changed firstly. Secondly, the structure of the first ball 16 and the second ball 17 can be modified so that the friction-reducing effect of the first ball 16 and the second ball 17 decreases as they move downwards, allowing the slider 7 to maintain a uniform sliding speed when sliding in the spiral guide groove 4.

[0057] Specifically, the first ball bearing 16 at the bottom of the spiral guide channel 4 and the second ball bearing 17 on the sidewall are designed with a gradient, such as denser distribution, smoother surface, and larger diameter at the upper end, and sparser distribution, moderately rougher surface, and smaller diameter at the lower end. This gradually increases the rolling friction resistance along the downward direction, thus counteracting the constant gravitational force on the slider 7 as it slides down, ultimately achieving uniform sliding of the slider 7. This design avoids vaccine impact damage caused by the slider 7 accelerating, ensuring vaccine safety, while also ensuring smooth sliding of the slider 7 to adapt to the vaccine retrieval structure, reducing retrieval errors. It also reduces impact wear on equipment components, extending service life, and eliminates the need for extreme adjustments to the guide channel's tilt angle, adapting to different vaccine specifications. Furthermore, it maintains a convenient operating procedure for vaccine storage and retrieval without adding extra burden. It also reduces the need for manual intervention by opening the hatch due to slider jamming, significantly reducing the risk of temperature fluctuations caused by cold leakage.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
