[0045] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0046] Example 1: This example proposes a multifunctional refrigerator box, such as... Figures 3-5 As shown, the refrigerator box 2 includes a box body 21 and a top cover 22, with the top cover 22 located at the upper opening of the box body 21.

[0047] A bracket 25 is installed inside the housing 21 near the upper opening. A heat preservation device is supported on the bracket 25, and the insulin pen 3 is placed in the heat preservation device 26. The heat preservation device 26 is used to isolate the internal temperature from the external temperature, so that the temperature inside the heat preservation device 26 is maintained at a constant temperature value.

[0048] The needle holder 24 is located inside the housing 21 below the bracket 25 and is used to fix the needle 4.

[0049] In some embodiments, the refrigerator box 2 further includes a temperature detection element and an alarm element 29. The temperature detection element is disposed within the insulation device 26 and is used to detect the temperature within the insulation device 26. The alarm element 29 is disposed within the box body 21 and is used to issue an alarm when the temperature within the insulation device 26 exceeds a safe limit, indicating that the stored medicine is no longer safe.

[0050] In some embodiments, the refrigerator box 2 also includes a charging board 27 and a power storage module 20. The charging board 27 is disposed inside the box body 21 and has a charging interface for connecting to a power source to charge the power storage module 20.

[0051] An alarm element 29 is disposed on the charging board 17, and the alarm element 29 may include an LED light and / or a buzzer.

[0052] When the alarm element 29 includes an LED light, a light-transmitting hole is provided on one side of the housing 21 to transmit the light emitted by the LED light for easy observation by the user.

[0053] In some embodiments, the refrigerator box also includes a lower cover 23. The box body 21 has a lower opening, and the lower cover 23 is disposed at the lower opening of the box body 21. Since the box body 21 is narrow and deep overall, items can be placed and taken out from both ends by means of the upper and lower openings of the box body 21, without interference, thus improving convenience.

[0054] In some embodiments, the needle holder 24 is disposed inside the housing 21 and near the lower opening, and the needle holder 24 is used to fix the needle. The user can remove and place the needle 4 disposed in the needle holder 24 by opening the lower cover 23.

[0055] To prevent dust from entering the box, a lampshade is provided on the charging board 17 or the box 21, which can be matched with the light-transmitting hole to seal it, so as to allow light to pass through while protecting the cleanliness of the internal space of the box 21.

[0056] The energy storage module 20 is installed inside the housing 21 and is used to power the alarm element 29 and the temperature detection element. The energy storage module 20 is electrically connected to the charging interface.

[0057] In some embodiments, the energy storage module 20 can be implemented using a lithium battery.

[0058] In some embodiments, the charging plate 17 is fixed to the bracket 25. Specifically, the end of the bracket 25 away from the rotating connection portion extends downward to form an end plate 253, and the charging plate 17 is fixed to the side of the end plate 253 facing the light-transmitting hole.

[0059] This portable insulin cooler box features openings at both the top and bottom, allowing for easy access to items from either end. One end holds the insulin pen, while the other holds several insulin needles. Each insulin pen can carry one insulin needle and cartridge, maximizing space utilization within the box to store all necessary insulin injection supplies. Its compact design makes it easy to carry. An insulation device inside the cooler box keeps the insulin in the needles of the insulin pen cool and warm.

[0060] In some embodiments, the heat preservation device 26 includes a vacuum chamber fixing member 261 and a vacuum chamber 263. The vacuum chamber fixing member 261 is rotatably connected to the bracket 25 via a rotating connection. The vacuum chamber fixing member 261 has an inner cavity, and the end of the vacuum chamber fixing member 261 away from the rotating connection has an opening communicating with the inner cavity.

[0061] The vacuum chamber 263 is inserted into the inner cavity through the opening of the vacuum chamber fixing member 261. A liner 264 is disposed inside the vacuum chamber 263, with a liner opening at one end adjacent to the opening. An insulin pen 3 carrying insulin is inserted into the liner 264 through the liner opening. The wall of the vacuum chamber 263 has a double-layered structure, and the interior is vacuumed, which slows down heat transfer. Therefore, the liner 264 located in the vacuum chamber 263 can be kept in a relatively constant temperature environment to facilitate the preservation of the insulin drug.

[0062] In order to reduce the temperature inside the vacuum chamber 263 and achieve a refrigeration effect, a sealed phase change cavity is formed between the liner 264 and the vacuum chamber 263. The phase change cavity is filled with phase change material. When the phase change material undergoes a phase change, it absorbs heat and carries away the heat in the vacuum chamber 263 to achieve cooling.

[0063] In some embodiments, in order to improve the heat preservation performance of the vacuum chamber 263, a sealing connector 265 is provided at the port of the vacuum chamber 263. The sealing connector 265 is used to seal the insulin pen 3 and the port of the vacuum chamber 263 to prevent the gap between the two from causing heat exchange between the inner and outer spaces.

[0064] Since only the cartridge portion of the insulin pen 3 needs to be refrigerated due to the storage of medication, while other parts do not require refrigeration, in order to reduce the volume of the vacuum chamber 263, in this embodiment, it is preferable that the cartridge portion of the insulin pen 3 extends through the sealing connector 265 into the liner 264. The sealing connector 265 is used to seal the port between the insulin pen 3 and the vacuum chamber 253.

[0065] In some embodiments, the sealing connector 265 may include a sealing ring.

[0066] In some embodiments, the top cover 22 is fixed to the vacuum chamber fixing member 261, and when one end of the vacuum chamber fixing member 261 can rotate around the rotating connection part connected to the bracket 25, it can rotate out of the box body 21 together with the top cover 22, so that the opening of the liner 264 faces outward, making it convenient to take out and put in the insulin injection pen.

[0067] To facilitate the connection between the vacuum chamber fixing member 261 and the bracket 25, in some embodiments, the rotating connection part includes a rotating shaft 266 symmetrically arranged on the two side walls of the vacuum chamber fixing member 261. Support arms 251 extend upward from both sides of the bracket 25, and the support arms 251 are provided with rotating shaft holes 252 that match the rotating shaft 266. The rotating shaft 266 is inserted into the corresponding rotating shaft hole 252.

[0068] To facilitate the assembly of the vacuum chamber fixture 261 and the vacuum chamber 263, and to facilitate the fixing of the top cover 22, in some embodiments, the top cover 22 and the vacuum chamber fixture 261 are detachably connected.

[0069] like Figure 5 , Figure 6 As shown, several slots 2611 are formed on the two side walls of the vacuum chamber fixing member 261 along the length direction, and claws 221 corresponding to the slots 2611 are formed on both sides of the upper cover 22. The claws 221 can be detachably inserted into the slots 2611.

[0070] The top cover 22 includes an outer cover 222 and an inner cover 223. The outer cover 221 and the inner cover 222 can be snapped or glued together, and the claw 221 is formed on the inner cover 223.

[0071] The bracket 25 extends downward to form a connecting ear 268 near the rotating connection part. A gear 269 is provided on the connecting ear 268. A buffer part 2614 is formed below the end of the vacuum chamber fixing member 261 near the rotating connection part. A notch 2612 with an inclined downward opening is provided on the buffer part 2614. The inner wall of the notch 2612 is straight on the side near the rotating connection part and has a rack 2613. The inner wall of the notch 2612 is curved on the side away from the rotating connection part. The gear 269 is located in the notch 2612 and meshes with the rack 2613.

[0072] like Figure 7 As shown, by pressing one end of the top cover 22 near the rotating connection, the top cover 22, together with the vacuum chamber fixing member 261, rotates around the axis and rotates out of the box body 21. The gear 269 rotates in the notch 2612 and meshes with the rack 2613 to achieve smooth transmission.

[0073] A support spring 267 is also connected between the vacuum chamber fixing component 261 and the bracket 25. One end of the support spring 267 is connected to the buffer part 2614, and the other end is connected to the connecting ear 268. When the upper cover 22 is pressed near the rotating connection part, the heat preservation device 26 and the upper cover 22 rotate around the rotating shaft 266, opening the upper cover 22. Figure 7 As shown, the support spring 267 provides support force to the vacuum chamber fixing member 261, pressing against the vacuum chamber fixing member 261 and the vacuum chamber 263 to keep them in the open state.

[0074] The top cover 22 can be closed by pressing the end of the top cover 22 away from the rotating connection.

[0075] In some embodiments, a magnetic adsorption device is provided between the lower cover 23 and the box body 21, and the two are fixed by magnetic attraction.

[0076] In some embodiments, the lower opening of the box 21 is a U-shaped notch, the needle fixing member 24 is engaged with the U-shaped notch, and the lower surface of the needle fixing member 24 has a plurality of needle assembly grooves, in which the needle is disposed.

[0077] The opening of the needle holder 24 is U-shaped and is inserted into the U-shaped notch at the lower end of the box 21.

[0078] A receiving space is formed between the upper part of the needle fixing member 24 and the bracket 25, and the energy storage module 20 and the control circuit board are arranged in the receiving space between the needle fixing member 24 and the bracket 25.

[0079] The shape of the lower cover 23 matches the shape of the needle holder 24, and after being connected to the box body 21, it is located outside the needle holder 24.

[0080] This embodiment also proposes an insulin cold storage device, such as... Figure 1 , Figure 2 As shown, the system includes a storage base station 1 and a refrigerator box 2, which are configured in conjunction. The refrigerator box 2 is used to store insulin medication, and the storage base station 1 is used to charge the refrigerator box 2, eliminating the need for a separate charging adapter for the refrigerator box 2. The internal storage space of the storage base station 1 can also store insulin medication, meeting the needs of users in different situations.

[0081] In some embodiments, such as Figure 2 As shown, the storage base station 1 includes a base station housing 11, a cooling chamber 12, a cooling module (not shown), and a power module. The base station housing 11 has internal storage space. The cooling chamber 12 is disposed within the base station housing 11 and has space for storing insulin drugs. The cooling module is disposed within the base station housing 11 and is used to cool the cooling chamber 12.

[0082] The power module is located inside the base station housing 11 and is used to power the cooling module. The power module is connected to a charging terminal 13, which extends to the outside of the base station housing 11 and is used to provide power to the refrigerator box 2.

[0083] The power module is connected to a built-in battery, which provides power to it; alternatively, the power module can be connected to an external power source, which provides power to it.

[0084] This embodiment of the insulin refrigerated storage device consists of two parts: a refrigerated box 2 and a storage base station 1. The refrigerated box 2 can be charged via the storage base station 1 without additional adapters. The refrigerated box 2 can hold an insulin pen 3, which carries a needle. By incorporating a heat preservation device 26 within the refrigerated box 2, the medication in the needle of the insulin pen 3 can be kept refrigerated and kept warm. The refrigerated compartment 12 of the storage base station 1 can store a certain number of needles. This solution combines portability and storage functionality, and is also convenient for charging.

[0085] In some embodiments, the base station housing 11 includes a lower shell 112 and a cover 111. The lower shell 112 has an internal accommodating space, and the cooling chamber 12 is disposed in the accommodating space inside the lower shell 112.

[0086] The cover 111 is hinged to the top opening of the lower shell 112. When the cover 111 is closed, it seals the accommodating space of the lower shell 112, thereby sealing the refrigeration chamber 12 in the accommodating space to prevent the loss of cold energy.

[0087] The insulin refrigerated storage device of this embodiment consists of two parts: a storage base station 1 and a refrigerated box 2. Each part has storage space that can be either refrigerated or insulated. The storage base station 1 has a large internal storage space and a refrigeration function, enabling it to store a relatively large amount of insulin medication. The refrigerated box 2 is smaller in size and can store a small amount of insulin medication, making it easy to carry. Furthermore, the storage base station 1 can charge the refrigerated box 2. The two working together provide users with sufficient storage space and meet their portability needs. Moreover, the charging function of the storage base station 1 eliminates the need for users to carry a separate charging adapter for the refrigerated box 2, further simplifying user operation.

[0088] In order to improve the stability of the refrigerator box 2 and save space occupied by the refrigerator box 2, in some embodiments, the upper surface of the cover 111 is formed with a recess 113 that matches the refrigerator box 2, and the charging terminal 13 is disposed on the bottom surface of the recess 113.

[0089] The charging interface is located at the bottom or side of the refrigerator box 2. By placing the refrigerator box 2 in the recess 113 of the storage base station 1 and aligning the charging interface with the charging terminal 13, the storage base station 1 charges the refrigerator box 2.

[0090] In some embodiments, the cover 111 and the lower shell 112 of the storage base station 1 are respectively provided with a first magnetic adsorption device 14, and the cover 111 and the lower shell 112 are fixed by magnetic adsorption.
