Whether it is to keep cold drinks cool in the hot summer or to keep hot drinks warm in the cold winter, they can easily cope with it. The high-quality stainless steel material is not only corrosion-resistant and easy to clean, but also ensures the purity and safety of the drinks, allowing people to enjoy delicious food while also gaining health protection. Thermos cups are diverse and fashionable in design, ranging from simple and portable to exquisite art, to meet the style needs of different people. Some styles are also equipped with humanized functions such as smart temperature control display and leak-proof sealing, making use more convenient and considerate.

[0003] The existing Chinese patent with announcement number CN210961348U discloses a thermos cup, including a cup body for holding hot water, a cup cover is provided on the cup body, a placement seat is provided below the cup body, a receiving groove is provided on the lower end surface of the placement seat, a cold water cup is provided in the receiving groove, a cover body is provided on the cold water cup to be matched with it, the cold water cup is slidably connected to the receiving groove, a slide groove is provided on the inner wall of the receiving groove, and a slider for inserting into the slide groove is provided on the cold water cup.

[0004] Although the above solution can adjust water of different temperatures as needed during use, the thermos cup lacks the function of warming hands. When the user uses the thermos cup in a cold environment, the hands may feel cold and uncomfortable due to exposure to low temperatures, affecting the comfort of use. Therefore, it does not meet the existing needs. In this regard, we propose a thermos cup with hand warming function. Utility Model Content

[0005] The purpose of the present invention is to provide a thermos cup that can warm hands, so as to solve the problem that the thermos cup proposed in the above background technology lacks the function of warming hands, which makes it uncomfortable to use in a cold environment.

[0010] Preferably, the outer wall of the shell is provided with high temperature resistant silicone, and the upper side of the interior of the shell is provided with a plurality of graphite columns distributed in a rectangular array, and the two ends of the graphite columns are conveniently bonded and fixed with the high temperature resistant silicone and the metal electric heating film.

[0011] Preferably, the battery cavity and the charging interface are connected via a charging circuit.

[0012] Preferably, an annular heat-insulating layer is adhered and fixed to the outer wall of the heat-insulating liner, and the annular heat-insulating layer is made of aerogel material.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This utility model is equipped with a metal electric heating film inside the shell. When the switch is turned on, the metal electric heating film can generate heat. The heat will be conducted to the shell through the graphite column, and the high-temperature resistant silicone is tightly wrapped around the outside of the shell, effectively isolating the heat from being directly transferred to the user. At the same time, the high-temperature resistant silicone layer also has good insulation properties to ensure safe use. When the user is in a cold environment, such as working or traveling outdoors in winter, just turn on the switch to quickly emit warmth, effectively relieve cold hands, promote blood circulation, and prevent frostbite.

[0015] 2. The utility model provides an annular thermal insulation layer on the outer wall of the thermal insulation liner. The annular thermal insulation layer is made of aerogel. As a new type of nanoporous material, aerogel has extremely low thermal conductivity and excellent thermal insulation performance. It can effectively block the transfer of heat in an extremely thin volume, thereby preventing external heat from being transferred to the thermal insulation liner through the outer shell during the hand warming process, ensuring the independence and stability of the internal temperature of the thermal insulation liner, and will not affect the insulation effect of the internal items due to external heating.

[0016] 3. The utility model opens a charging chamber on one side of the lower end of the shell. By pulling the lifting plate upward, the dustproof plate can be moved up, so that the battery in the battery chamber can be transmitted through the charging interface, achieving a long-term hand warming effect. When the lifting plate is released, the dustproof plate can be moved down under the elastic action of the return spring, so that the charging chamber can be sealed by the dustproof plate to prevent dust from entering the interior of the charging chamber, reducing the potential risks of poor contact and short circuit of the charging interface due to impurity accumulation, and keeping the charging interface clean, ensuring a smooth and efficient charging process.
