[0002] With advancements in medical technology, many well-known diseases can now be effectively treated. However, some medications require low-temperature storage. For instance, some diabetic patients need to use insulin long-term to control their condition. Insulin requires strict temperature control; insulin that needs long-term storage must be kept between 2 and 8 degrees Celsius. Opened insulin can be stored for up to four weeks at 2 to 25 degrees Celsius. Therefore, patients need containers that can refrigerate their medications. CN221830386U discloses a robust refrigeration cup lid, which connects a refrigeration mechanism and a power source via a shell.

[0003] Existing thermos cups have a single lid structure, and their shape differs greatly from that of ordinary water cups. When used, they are exposed and easily attract the attention of others. At the same time, this type of lid structure has poor heat preservation performance. Utility Model Content

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] A double-layer insulated cup lid includes an inner cup lid 1 and an outer cup lid 2. A cooling module 3 is disposed inside the inner cup lid 1. The outer cup lid 2 covers the inner cup lid 1 and includes a top cover 4 and a side cup sleeve 5. The outer cup lid has a ring-shaped structure covering the inner cup lid 1, and the top cover 4 is located on top of the inner cup lid 1. The cup sleeve 5 and / or the top cover 4 are vacuum insulated structures. In this embodiment, the cooling module 3 includes a cooling chip 9, a heat sink, a cooling fan, etc. The cooling chip 9 is generally a semiconductor cooling chip 9, and the cooling fan is used to dissipate the heat generated during the cooling process of the semiconductor cooling chip 9 to the outside. This solution provides a double-cup lid structure.

[0026] In this design, the middle part of the cup sleeve 5 is a vacuum insulation layer 6; the inner cup lid 1 and the outer cup lid 2 are connected by threads. Specifically, the cup sleeve 5 has a double-layer structure, which is formed by bending, and then the cavity formed by bending is vacuumed. The cup sleeve 5 and the upper cover 4 are detachably connected. The upper cover 4 can be a one-piece structure or composed of multiple units.

[0027] In this design, the inner cup cover 1 includes an upper top cover 2311. The edge of the top cover 2311 has an annular mounting groove 12 coaxial with the inner cup cover 1 and the outer cup cover 2. The side of the mounting groove 12 has an internal thread 13. The inner side of the upper cover 4 has a connecting part 21 with an external thread 14. The connecting part 21 is installed in the mounting groove 12 and threadedly engages with the internal thread 13 of the mounting groove 12. Since the cooling fan needs to dissipate heat, it requires an air inlet 15 and an air outlet. The air inlet 15 is located on the top cover 2311, specifically on the bottom surface or side wall of the mounting groove 12. In this design, the air inlet 15 is located at the bottom of the mounting groove 12. This design ensures the flatness of the upper surface of the inner cup cover 1 and does not affect the placement of components in the middle of the upper surface of the inner cup cover 1. The air outlet is located on the side of the inner cup cover 1.

[0028] The cup sleeve 5 is integrally formed by bending a sheet metal to create an inner plate 16 and an outer plate 17. The free ends of the inner plate 16 and the outer plate 17 are fixed at the upper end of the cup sleeve 5, forming a limiting piece 18. The limiting piece 18 extends towards the center of the space enclosed by the cup sleeve 5 and is inserted into the upper cover 4 to fix the cup sleeve 5 and the upper cover 4 together. This structural design facilitates the forming of the cup sleeve 5 and vacuuming, and the formed limiting piece 18 can also be used to install the upper cover 4.

[0029] In this design, the upper cover 4 includes a cover body and a connecting part 21. The cover body and the connecting part 21 are designed separately. The connecting part 21 is fixed on the limiting piece 18, which is a ring structure.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the upper cover 4 is equipped with a display screen and / or a touch unit. This solution also includes a temperature sensor 7, a temperature sensor 8, a cooling unit, and a controller 10. The controller 10 controls the power of the cooling unit based on the data collected from the temperature sensors 7 and 8. Temperature sensor 7 is used to collect the external temperature of the cup, and temperature sensor 8 is used to collect the temperature of the cooling cup 19. In this structure, the lid is pressed onto the top of the inner cup lid 1.

[0032] Example 3

[0033] A refrigerated thermos cup includes a double-layer refrigerated thermos cup lid as described in Embodiment 1 or Embodiment 2, a cup body 22, and a refrigerated cup cylinder 19 disposed within the cup body 22. The refrigerated thermos cup lid is also provided with a refrigeration module 3 and a heat conduction module 20. The heat conduction module 20 is attached to the cold end of the refrigeration module 3, and the heat conduction module 20 is fixedly connected to the refrigeration cup cylinder 19 by threads.

[0034] The heat-conducting module 20 is fixedly installed inside the cup lid. It has a connecting thread 1 for connecting the cooling cup cylinder 19. The axis of the connecting thread is coaxial with the cooling cup cylinder 19. The opening of the cooling cup cylinder 19 is provided with a connecting thread 2. The connecting thread 1 and the connecting thread 2 cooperate with each other. The cup body 22 has a double-layer vacuum structure.

[0035] Example 4

[0036] The difference between this embodiment and embodiment 1 is that the top cover 4 and the cup sleeve 5 are integrally formed, and the inside of the top cover 4 is also a vacuum structure.
