[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] In related technologies, existing vacuum insulated cups include an outer shell, an inner liner, and a heating element. A vacuum cavity is formed between the outer shell and the inner liner. The heating element is installed inside the vacuum cavity and contacts the outer wall of the inner liner to heat it. Because the heating element is easily damaged in a vacuum environment, the lifespan of vacuum insulated cups with heating functions is reduced.

[0023] Reference Figures 1 to 3 According to an embodiment of the present invention, a vacuum thermos cup with heating function includes an outer shell 100, an inner liner 200, and a membrane heating element 300. The inner liner 200 is disposed inside the outer shell 100, and a vacuum cavity 101 is formed between the outer shell 100 and the inner liner 200. The membrane heating element 300 is disposed inside the vacuum cavity 101 and is connected to the outer wall of the inner liner 200. In this way, by using the membrane heating element 300, the traditional method of heating the inner liner 200 with a heating tube can be abandoned, ensuring that the membrane heating element 300 is not damaged in a vacuum environment, thereby improving the service life of the vacuum thermos cup with heating function.

[0024] For example, when a vacuum insulated cup with heating function is working, the membrane heating element 300 is activated. The heat generated by the membrane heating element 300 is transferred to the inner liner 200 to heat the liquid inside the inner liner 200. By using the membrane heating element 300, the traditional method of heating the inner liner 200 with a heating tube can be eliminated, ensuring that the membrane heating element 300 is not damaged in a vacuum environment, thereby improving the service life of the vacuum insulated cup with heating function.

[0025] In some embodiments of this utility model, the film heating element 300 is a thick film heating layer. The thick film heating layer can be heated by electric current through screen printing process to realize the conversion of electrical energy into heat energy. The thick film heating layer can be applied to substrates made of materials such as stainless steel, ceramic, glass, and polyimide film. At the same time, the thick film heating layer has good heating performance in a vacuum environment, which can improve the service life of vacuum insulated cups with heating function.

[0026] It should be noted that the thick film heating layer includes a first insulating layer, a resistive layer and a second insulating layer stacked in sequence. The first insulating layer is located on the outer wall of the inner liner 200. When the film heating element 300 is energized, the resistive layer heats up to heat the liquid inside the inner liner 200. This is not limited here.

[0027] In some embodiments of this invention, the membrane heating element 300 is a membrane heating sheet. Membrane heating sheets typically employ an ultra-thin structure, with a thickness of only a few micrometers to tens of micrometers, allowing for easy adhesion to various complex surfaces. Furthermore, membrane heating sheets maintain stable performance at extremely high temperatures. For example, heating sheets using polyimide film as the substrate exhibit excellent high-temperature resistance, suitable for temperatures ranging from -40°C to 280°C. Membrane heating sheets also demonstrate good heating performance in a vacuum environment, thereby extending the lifespan of vacuum-insulated cups with heating functions.

[0028] In some embodiments of this utility model, the vacuum thermos cup with heating function also includes a temperature detection element 400. The temperature detection element 400 is disposed in the vacuum chamber 101, and the detection end of the temperature detection element 400 contacts the inner liner 200 to detect the temperature of the inner liner 200. It can detect and monitor the temperature of the inner liner 200 in real time, thereby making it convenient for users to use.

[0029] It should be noted that the temperature sensing element 400 can be a thermocouple temperature sensor or a resistance temperature sensor, etc., and there are no restrictions here.

[0030] In some embodiments of this utility model, the membrane heating element 300 is provided with a first through hole 301 that penetrates the membrane heating element 300, and the temperature sensing element 400 is disposed in the first through hole 301, which can reduce the overall height of the vacuum insulated cup with heating function, so as to facilitate carrying and packaging the vacuum insulated cup with heating function.

[0031] For example, by inserting the temperature sensing element 400 into the first through hole 301, the overlap height between the temperature sensing element 400 and the first through hole 301 can be eliminated in the vacuum insulated cup with heating function, thereby reducing the overall height of the vacuum insulated cup with heating function, making it easier to carry and package.

[0032] In some embodiments of this utility model, the inner liner 200 is provided with a cavity 210, the bottom wall of the cavity 210 is provided with a protrusion 220, and the inner liner 200 is provided with a groove 230 on the side facing the bottom of the outer shell 100. The detection end of the temperature detection element 400 is accommodated in the groove 230, which facilitates the installation and positioning of the temperature detection element 400.

[0033] It should be noted that by setting the groove 230, the temperature of the inner liner 200 can be radiated to the temperature sensing element 400 through the bottom wall and side wall of the groove 230, which can improve the accuracy of the temperature sensing element 400 measurement.

[0034] In some embodiments of this utility model, the bottom of the housing 100 is provided with a second through hole 110, and the lead end 302 of the film heating element 300 extends to the outside of the housing 100 through the second through hole 110, which facilitates the lead of the film heating element 300.

[0035] In some embodiments of this utility model, the membrane heating element 300 is connected to the side of the inner liner 200 facing the bottom of the outer shell 100, which facilitates heating of the inner liner 200.

[0036] In another embodiment, the membrane heating element 300 is connected to the outer peripheral wall of the inner liner 200, which facilitates heating of the inner liner 200.

[0037] In another embodiment, the heating element includes a first heating part 310 and a second heating part 320. The first heating part 310 is connected to the side of the inner liner 200 facing the bottom of the outer shell 100, and the second heating part 320 is connected to the outer peripheral wall of the inner liner 200. By setting the first heating part 310 and the second heating part 320, the bottom and peripheral wall inside can be heated at the same time to improve the heating efficiency of the vacuum thermos cup with heating function.

[0038] In some embodiments of this utility model, the outer peripheral wall of the inner liner 200 is provided with a receiving groove 240, which extends to the side of the inner liner 200 facing the bottom of the outer shell 100. At least a portion of the membrane heating element 300 is accommodated in the receiving groove 240, which can reduce the overall volume of the inner liner 200 and the membrane heating element 300, thereby reducing the overall volume of the vacuum insulated cup with heating function, so as to facilitate carrying and transporting the vacuum insulated cup with heating function.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
