Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to an ultra-portable medicine refrigerator with temperature regulation function. Background Technology

[0002] With the development of medical technology, more and more refrigerated medicines have become the first-line treatment option for doctors to treat patients. Refrigerated medicines refer to medicines that require cold storage temperatures for transportation and storage. Due to the special nature of their chemical structure or dosage form, their stability is greatly affected by changes in factors such as temperature, light (natural light, artificial light, strong light), vibration, humidity, and storage time. If not stored and transported according to regulations, the medicine may undergo physical and chemical changes, resulting in reduced activity, deterioration, or ineffectiveness, affecting the efficacy of the medicine, and even causing serious toxic reactions.

[0003] Clinically, commonly refrigerated medications are generally biological products, including insulin, vaccines, blood products, protein products, interferon, cytokines, monoclonal antibodies, and oral live bacteria preparations. Most biological products are protein-peptide derivatives, which have poor stability and are highly susceptible to temperature changes. Therefore, refrigerated medications typically need to be stored in a cool place between 2-10°C, and opened insulin should be stored at room temperature below 30°C. Due to the special nature of refrigerated medications, excessively high or low temperatures can affect their quality; therefore, maintaining a complete cold chain is crucial. However, patients may need to travel for business, leisure, work, or school, or the journey home from picking up medication may lack refrigeration facilities, potentially leading to quality issues, preventing the medication from achieving its intended therapeutic effect, and even causing adverse reactions. Therefore, smaller, portable refrigerated boxes have been developed.

[0004] For example, the Chinese patent document "A Multifunctional Medicine Refrigerator, Publication No. CN219707858U" has a refrigerator box on the top of the box, a storage box on the front of the box, and a storage slot on the back of the box, with a cover hinged to one side of the storage slot; insulin and various tools are placed in the refrigerator box and the storage box to facilitate their carrying and use.

[0005] As mentioned above, portable refrigerated medicine devices on the market are generally powered by dry cell batteries or lithium batteries. Lithium batteries are more expensive and more suitable for long-term use of three to five years, while dry cell batteries have a shorter lifespan but are cheaper and more suitable for short-term use of one to two months. In order to have a longer battery life, larger capacity batteries are used, resulting in a larger overall weight and disadvantages such as large size and inconvenience in carrying. For scenarios where patients need to temporarily carry small or few medications, a small refrigerated medicine box is the recommended choice. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned problems by providing an ultra-portable medicine cooler with temperature regulation function, which allows the number of batteries to be adjusted according to actual needs, so that users can choose between lightweight portability or long battery life.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An ultra-portable medicine refrigerator with temperature regulation function includes a box body, a temperature control component, a refrigeration component, and a battery holder. The box body includes a box body and a box lid. A refrigerator cavity with a top opening is provided at the right end of the box body, and a device cavity is provided at the left end of the box body. The box lid closes to the opening of the refrigerator cavity. The refrigeration component and the battery holder are located in the device cavity. The electrodes of the battery holder are electrically connected to the refrigeration component and the temperature control component respectively to supply power. The temperature control component is electrically connected to the refrigeration component to regulate and control the temperature of the refrigerator cavity. The battery holder includes a battery compartment and a compartment cover. A compartment opening is provided on the side wall at the left end of the box body. The compartment opening is covered by the compartment cover. The battery compartment is located in the middle of the compartment opening. The battery compartment includes two sets of compartment seats to assemble one or two pairs of batteries, and the electrodes of the two sets of compartment seats are connected in parallel.

[0009] The box body is 126mm long, 68mm wide, and 36mm high. The temperature control component includes a touch screen and a control board. The control board is electrically connected to both the touch screen and the refrigeration component. The touch screen is located on the top surface of the equipment cavity within the box body.

[0010] The battery compartment is a cylindrical battery holder. The bottom of each cylindrical battery holder has wiring electrodes for electrical connection to the refrigeration and temperature control components. Two cylindrical battery holders form one set. The cover has series electrodes corresponding to the positions of each set of cylindrical battery holders. The wiring electrodes of the two sets of cylindrical battery holders are connected in parallel. The two sets of cylindrical battery holders are arranged side-by-side.

[0011] As mentioned above, the battery compartment of the refrigerator box includes two sets of compartment seats, and the electrodes of the two sets of compartment seats are connected in parallel. Thus, the number of batteries can be adjusted according to actual needs. One pair of batteries can be installed to make it lighter, or two pairs of batteries can be installed to make it have a longer battery life but heavier.

[0012] Based on the aforementioned solution, in an improved solution, a hanging hole is provided at the left end of the box to allow for the insertion of a hanging rope.

[0013] Based on the aforementioned solution, in an improved solution, hemispherical silicone protrusions are provided at the four corners of the bottom of the box to provide anti-slip and cushioning effects.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] This utility model discloses an ultra-portable medicine cooler with temperature regulation function. A battery compartment is set on the left side wall of the box body.

[0026] Example 1

[0027] See Figures 1-8This embodiment of an ultra-portable medicine refrigerator with temperature regulation function includes a box body 1, a temperature control component, a refrigeration component, and a battery holder. The box body 1 includes a box body and a box cover 12. A refrigerator cavity 16 with a top opening is provided at the right end of the box body, and a device cavity is provided at the left end of the box body. The box cover 12 is closed at the top opening of the refrigerator cavity 16. The refrigeration component and the battery holder are provided in the device cavity. The electrodes of the battery holder are electrically connected to the refrigeration component and the temperature control component respectively to supply power. The temperature control component is electrically connected to the refrigeration component to regulate and control the temperature of the refrigerator cavity. The battery holder includes a battery compartment and a compartment cover. A compartment opening is provided on the side wall of the left end of the box body, and a compartment cover (battery cover) is closed at the compartment opening. The battery compartment is located in the middle of the compartment opening. The battery compartment includes two sets of compartment seats to assemble one or two pairs of batteries, and the electrodes of the two sets of compartment seats are connected in parallel.

[0028] The refrigerator box includes a temperature control component comprising a touch screen 11 and a control board 18, with the control board electrically connected to both the touch screen and the refrigeration component. The refrigeration component uses a semiconductor refrigeration element, with its refrigeration end face closely attached to the refrigerator cavity. The touch screen is located on the top surface of the device cavity within the box, and includes temperature setting buttons, a battery level display button, a battery display area, a real-time temperature display area (showing the corresponding set value when adjusting the temperature), and quick temperature level buttons. It also features a heat dissipation structure, including an air inlet and an air outlet, and a micro DC fan can be configured as needed. The refrigerator box, its temperature control component, refrigeration component, battery compartment, and connection control are all existing technologies and will not be described in detail here. This application improves upon existing refrigerator boxes by configuring the battery compartment structure as two parallel sets.

[0029] Existing refrigerators use either rechargeable NiMH batteries or non-rechargeable dry cell batteries. For rechargeable NiMH batteries, a charging interface is provided for charging via a USB-C cable. Therefore, the two parallel compartments of this application can be two parallel cylindrical compartments (equipped with either rechargeable NiMH batteries or non-rechargeable dry cell batteries), or one set of batteries can be used independently, as shown in the figure. Here, we will illustrate this with an example of two parallel cylindrical compartments, each with two (one pair) batteries.

[0030] Therefore, the battery compartment is a cylindrical battery holder 17, equipped with a charging interface 181. The inner bottom of the cylindrical battery holder 17 is equipped with wiring electrodes for electrical connection to the cooling component and the temperature control component, respectively. Two cylindrical battery holders 17 form a set. The cover has series electrodes corresponding to the position of each set of cylindrical battery holders, and the wiring electrodes of the two sets of cylindrical battery holders are connected in parallel. Figure 2 and Figure 4 As shown, the positive terminal has a circular protrusion and the negative terminal has a spring. The corresponding "+" and "-" electrode markings are indicated on the battery cover. The same group is enclosed by a line to remind the user to use the correct single battery pack. The battery compartment cover is bolted to threaded hole 19. Figure 7As shown, the two sets of terminals are connected in parallel, with the positive and negative terminals connected to a and b respectively. This battery holder uses existing components that can be readily used in the market, such as those found in Chinese patent applications "Novel Dry Battery Box, Publication No. CN108493375A" and "A Battery Box Assembly for Easy Disassembly, Publication No. CN212725444U". This application simply sets the quantity to two and connects them in parallel using wires or copper sheets, which is sufficient for this purpose. Further details will not be provided here.

[0031] See Figure 4 The two sets of cylindrical battery holders are arranged in two layers, so that whether one or two pairs of batteries are inserted, they are laid out flat to avoid excessive shifting of the focus.

[0032] See Figures 2-6 The dimensions of the box body are given in mm. The box body is 126mm long, 68mm wide, and 36mm high. The top surface of the equipment cavity area is 68mm x 32mm. A magnetic closure is provided at the lid's closing point. At the center of the refrigeration cavity opening is a recessed opening 101 with a height of 8mm, a width of 25mm, a top depth of 3mm, and a bottom depth of 0-1mm. The cross-section of the recessed opening 101 is an inverted trapezoid or inverted triangle. Figures 1-3 As shown, the groove opening in this embodiment is illustrated by an inverted triangular structure, with a height of 8mm, a width of 25mm, a top depth of 3mm, a bottom depth of 0mm, and a cross-section of its wall surface in the shape of an inverted triangle.

[0033] like Figure 3 As shown, the hinge for the cover is located on the back side, while the cover opening is on the front side with a recessed opening. Placing the battery compartment on the left and the storage box on the right is convenient for most right-handed users; conversely, placing them on the left side is more convenient for left-handed users. To use, first remove the cover and insert one or two pairs of batteries; then, turn on the switch and set the temperature. Figure 5 As shown, then start running, as follows Figure 6 As shown; finally, open the lid, put in the medicine to be refrigerated (2), and close the lid.

[0034] As mentioned above, the refrigerator box has a battery compartment on the left side wall of the box body. The battery compartment includes two sets of battery holders, and the electrodes of the two sets of battery holders are connected in parallel. In this way, the number of batteries can be adjusted according to actual needs. One pair of batteries can be installed to make it lighter but with a shorter battery life, or two pairs of batteries can be installed to make it with a longer battery life but with a heavier weight. This allows users to choose between lightweight portability or long battery life, improving the user experience.

[0035] Example 2

[0036] Based on Example 1, this example includes a hanging rope structure, as detailed below:

[0037] See Figures 1-6 The left end of the box is provided with a hanging rope hole 15, which is specifically located at the four corners. A vertically opened annular channel (hanging rope hole 15) is provided, leaving a hanging section in the middle, which is cylindrical in shape, so that the hanging rope can be threaded through the hanging rope hole and hung on the hanging section.

[0038] Example 3

[0039] Based on Example 1 or Example 2, this example has an anti-slip structure, as detailed below:

[0040] See Figures 1-6 The box has hemispherical silicone protrusions at the four corners of its bottom, which are attached with adhesive or bolts to prevent slipping and provide cushioning.

[0041] Example 4

[0042] The difference between this embodiment 4 and the aforementioned embodiment 1 lies in the distribution structure of the cylindrical battery holder, as detailed below:

[0043] See Figure 9 Two sets of cylindrical battery holders are arranged in two layers, left and right. With a top-and-bottom layer, if the battery compartment is larger than the battery diameter, and the user only loads the top layer, the lower layer has no support and is prone to shifting due to gravity. However, with one set on each side, whether one or two pairs of batteries are inserted, they are tightly supported, reducing the risk of shifting. The battery cover is marked with corresponding "+" and "-" electrode symbols, and two sets are arranged on each side, each enclosed in a wireframe.

[0044] As described in Examples 1-4 above, this utility model aims to design an ultra-portable refrigerated medicine box that is small in size, exquisite in appearance, has a long standby time, is easy to power, has a low battery reminder, and can be easily adjusted in temperature. It can be taken on high-speed trains and airplanes, carried with you when traveling, and used in places without refrigeration facilities such as dormitories and hotels. It is easy to power and meets the refrigeration and insulation requirements of business trips, travel, work, school, and returning home after picking up medicine.

[0045] Its temperature control range is 2-25℃, which can be cycled according to temperature requirements. It features a real-time temperature display on an electronic touchscreen, intelligent temperature adjustment via touch buttons (the portable version can be set to 25℃ after insulin is turned on, saving energy and providing immediate use), battery level display and low battery warning (a buzzer alarm and red light when the battery level is below 20%, a yellow progress bar for 20-50% battery level, and a green progress bar for 51-100% battery level), a power button, and three quick temperature settings (5℃, 15℃, and 25℃). Its ultra-narrow bezel, extra-large touchscreen display provides clear and large text, making it easy for the elderly to use. Figure 5As shown, the screen includes a display area 112 and buttons 111, including a power switch, a temperature setting button, a setting button, and a battery button. Clicking the setting button increases the temperature from low to high, cycling between the minimum and maximum values. Turning on the power switch allows you to set the temperature as needed, from 5°C to the desired temperature. Clicking the battery button displays the remaining battery level. A long press locks the touchscreen to prevent accidental touches. Figure 6 As shown, the battery level is 50% and the real-time temperature is 15°C.

[0046] Its box body adopts a double-layer structure, such as Figure 8 As shown, the inner layer of the refrigeration chamber is a vacuum layer 102. The vacuum layer 102 is 3mm thick and made of 1mm thick aerospace aluminum or stainless steel to improve insulation. The outer layer of the refrigeration chamber is an outer shell 102. The outer layer of the refrigeration chamber and the equipment cavity are made of a plastic outer shell 103 with a thickness of 1-1.5mm. The outer wall of the outer shell is covered with a white paint coating 104 with a thickness of 0.3-0.5mm. The overall thickness of the painted outer shell (outer shell 103 and paint coating 104) is 1.8mm, with smooth, curved edges.

[0047] The lid (box lid) opens by flipping upwards; the opening of the refrigerator compartment features a recessed arc design for easy opening and closing; the lid and box body are magnetically connected to increase the box's airtightness. It also has lanyard holes at the four corners.

[0048] Its USB-C port allows for charging via an external power bank or charger. It uses four 1.5V AA fast-rechargeable NiMH batteries, each with a capacity of 9800MWh. These batteries are replaceable and can be directly charged, providing a battery life of 72 hours or more. It can also be powered by two batteries to reduce overall weight and meet daily heat retention needs. Alternatively, it can be powered by dry cell batteries in situations where immediate charging is not possible. All four batteries can operate simultaneously or in pairs; two batteries form a circuit, and each circuit can operate independently or simultaneously. If the user is only going out for one day and doesn't want to carry all four batteries, installing only two batteries achieves a lightweight and highly portable design. If all four batteries are installed simultaneously, the battery life can reach 3 days or more, suitable for long-distance use.

[0049] Its side walls feature grille-style dustproof and heat dissipation vents. Circular silicone dots are placed at the four corners of the bottom of the box for anti-slip and cushioning purposes.

[0050] Its refrigeration chamber can accommodate commonly used outpatient and emergency medications, such as bottled medications like Jiefu (102mm*23mm*23mm) and blister packs like Bifidobacterium (79mm*56mm), meeting the needs of 1-3 days or more. It is also compatible with other smaller medications requiring refrigeration, such as eye drops, capsules, insulin cartridges, and topical biological agents like Befuji, ensuring minimal and ultra-portable storage for daily medication needs. It can be purchased or rented from pharmacies near hospitals, vending machines near pharmacies, and online shopping platforms to meet immediate refrigerated medication storage requirements. Due to its ultra-thin design, the refrigeration chamber has a small capacity, low power consumption, and significantly increased battery life. Its ultra-small capacity allows for storage of only insulin cartridges without refrigerating the pen itself, improving energy efficiency and portability. Commercially available multi-functional refrigerators are quite bulky, and many patients only need to store one tube of topical ointment or spray, eye preparation, or a blister pack of oral tablets. The refrigerator in this application is more than half the size of those on the market, meeting the needs of users who require a large refrigerator for 1-3 days.

[0051] It should be noted that the examples of the above embodiments can preferably be combined with one or more of each other according to actual needs, and the accompanying drawings of multiple examples adopt a set of combined technical features, which will not be described in detail here.

[0052] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

However, these descriptions are not intended to limit the scope of protection claimed by the present utility model. All equivalent changes or modifications made under the technical teachings of the present utility model shall fall within the patent protection scope covered by the present utility model.
