Description

Technical Field

[0001] This utility model belongs to the field of refrigeration cup technology, specifically relating to a portable refrigeration cup. Background Technology

[0002] In the existing field of refrigeration and insulation equipment, most similar products use semiconductor cooling chips as the refrigeration element. Their cold storage compartments are generally designed as a single, integrated structure, and are not fully enclosed, resulting in low refrigeration efficiency. In practical use, these devices cannot directly store bulk liquids, and it is extremely inconvenient for users to retrieve and place items. Furthermore, the ice crystals used in existing equipment are mostly semi-enclosed, unable to fully cover refrigerated items, and some ice crystals are made of plastic, which has significant shortcomings in terms of refrigeration performance and durability. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a portable cooling cup.

[0004] Improving Refrigeration Efficiency and Ease of Use: This utility model aims to significantly improve the utilization rate of refrigeration efficiency and substantially enhance refrigeration efficiency. The design fully considers user convenience, effectively solving the problem of inconvenient access to items, and allowing direct storage of bulk liquid items in the refrigerated compartment. The use of a stainless steel outer shell for the ice crystals not only enables efficient freezing but also facilitates rapid transfer of cooling capacity during refrigeration.

[0005] Optimized structural design: The cold storage compartment adopts a split and fully enclosed design, as does the ice crystal. This structure effectively preserves and utilizes cold energy, reduces cold loss, and further improves refrigeration and insulation performance.

[0006] Multiple power supply options and insulation design: The device is primarily powered by DC power, but can be flexibly powered by a power bank or adapter. It utilizes semiconductor refrigeration principles to generate cooling, which is then conducted to the refrigerated compartment via aluminum conductive sheets. Ice crystals are placed on the outer layer of the refrigerated compartment; these crystals provide insulation when no power supply is available. The outer layer of the ice crystals adopts a double-walled stainless steel vacuum insulated cup structure, effectively keeping the contents warm and extending their refrigeration and preservation time.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] High-efficiency cooling and insulation: By optimizing the cooling structure and using stainless steel ice crystals, the cooling efficiency and cold transfer speed are improved, and the items can still be kept warm for a long time after the power is off, ensuring that the items are always in a suitable temperature environment.

[0009] Ease of use: The split-type and fully enclosed refrigerated compartments make it easy to put and take out items, while also safely storing bulk liquids, meeting the needs of different users.

[0010] Structural durability: The ice crystal outer shell of the stainless steel double-walled vacuum insulated cup not only improves the heat preservation performance, but also enhances the overall durability of the device and extends the product's service life. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown;

[0021] A portable cooling cup, comprising an outer cup 1 with a stainless steel double-walled vacuum insulated structure and an electronic cooling lid.

[0022] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "In the field of existing refrigeration and insulation equipment, most similar products use semiconductor cooling chips as refrigeration elements. Their refrigeration compartments are generally designed as an integrated structure and are not fully enclosed, resulting in low refrigeration efficiency. In actual use, such equipment cannot directly store bulk liquids, and it is extremely inconvenient for users to retrieve and place items. At the same time, the ice crystals equipped in existing equipment are mostly semi-enclosed structures, unable to fully cover refrigerated items, and some ice crystals are made of plastic materials, which have significant deficiencies in refrigeration performance and durability." Considering practical use, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, a portable cooling cup is provided.

[0023] like Figure 1-4 As shown in the figure;

[0024] In conjunction with the above, it also includes a DC power supply module, a semiconductor refrigeration chip, a refrigerator compartment 4, and ice crystals 2. The electronic refrigeration cover includes a cup lid 5, an upper cover 6, a top cover 7, an aluminum conductive sheet 8, and a fan 9. The DC power supply module is used to supply power to the semiconductor refrigeration chip, and the cooling energy generated by the semiconductor refrigeration chip is conducted to the refrigerator compartment 4 through the aluminum conductive sheet 8.

[0025] The refrigerator compartment 4 adopts a split and fully enclosed design. The ice crystals 2 are fully enclosed on the outer layer of the refrigerator compartment 4. The outer layer of the ice crystals 2 is the outer cup 1 of a stainless steel double-walled vacuum insulated cup structure.

[0026] It also includes an NTC thermistor 10, a control panel 11, an inner cup silicone 3, a heat insulation cotton 12, a heat sink 13, and a control electronic board 14. A fan 9 is provided above the heat sink 13, and the fan 9 sends air to the airflow channel for heat exchange and then discharges the air.

[0027] The NTC thermistor 10 is used to monitor the temperature inside the refrigerator compartment 4 and transmit the signal to the control electronic board 14, which controls the working state of the semiconductor refrigeration chip according to the temperature signal.

[0028] The control panel 11 is used to display temperature and control operation. The inner cup silicone 3 is placed inside the refrigerator compartment 4 to prevent bulk liquid leakage. The heat insulation cotton 12 is used to reduce cold loss. The heat sink 13 is used to assist the semiconductor cooling chip in heat dissipation.

[0029] The DC power supply module can be powered by a power bank or an adapter.

[0030] Ice Crystal 2 features a stainless steel casing.

[0031] Power supply and cooling process: When this device is needed, connect a DC power source (such as a power bank or adapter) to the device. After the power is turned on, the current passes through the control electronic board, driving the semiconductor cooling chip to work. The semiconductor cooling chip generates cooling energy, which is quickly conducted to the refrigerated compartment through the aluminum conductive sheets, causing the temperature inside the refrigerated compartment to drop rapidly, thus cooling the stored items.

[0032] The cooling and insulation functions of ice crystals: During the cooling process, the ice crystals (stainless steel outer shell) in close contact with the refrigeration compartment rapidly freeze at low temperatures. When the device is powered off, the ice crystals release the stored cold energy to keep the items inside the refrigeration compartment warm. Because the outer layer of the ice crystals is a double-walled stainless steel vacuum insulated cup structure, heat transfer is effectively reduced, extending the insulation time.

[0033] Storage of bulk liquids and retrieval of items: The modular design of the refrigerated compartment facilitates the storage and retrieval of items. Its fully enclosed structure and inner silicone cup design ensure that no leakage occurs when storing bulk liquids. Users can easily place various bulk liquid items into the refrigerated compartment for cold storage.

[0034] Temperature control and display: The NTC thermistor monitors the temperature inside the refrigerated compartment in real time and transmits the temperature signal to the control board. The control board displays the current temperature on the control panel screen according to the preset temperature value, and simultaneously controls the operating status of the thermoelectric cooler to maintain a stable temperature inside the refrigerated compartment.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
