Background technique

In daily life, when people drink warm water or make coffee, they usually pour the heated boiled water into the water cup. They need to wait for a period of time for the temperature of the hot water to drop to the temperature that the human body is comfortable with. It will cool down, so I don’t know how long it will take to adapt to the temperature of the human body’s taste before drinking it. The traditional method is that if the boiled water is too cold, you have to reheat the water and mix it with heat to drink the ideal warm water. If the coffee is too cold and the water is reheated, the taste will not taste good, and there will be no feeling of drinking coffee, which will waste a lot of time.

When in use, the receiving coil 23 can be aligned with the mobile phone wireless charger for wireless charging, and the heating part 22 can generate heat to keep warm and heat the cup body 10 . Using the mobile phone wireless charger to replace the 110-220V AC power supply greatly expands the use environment and is convenient for travel. In addition, the heat generating part 22 is arranged in the casing 21 to prevent burns. The shell 21 and the cup body 10 are hermetically connected, and the whole is waterproof, which is convenient for cleaning the cup without damaging the circuit. Wherein, the mobile phone wireless charger can be a Qi wireless charger for charging the mobile phone.

In this embodiment, the heating part 22 is a heating thin film made of graphene. Compared with the existing heating block, the heating thin film can use DC low-voltage 5V power supply to generate heat, and has the advantages of small size, light weight and low power consumption. The structure of the thermos cup is more compact and light, and it is easy to carry. Further, the heating device 20 also includes a circuit control board 24 for controlling the circuit. The circuit control board 24 is installed in the casing 21 and electrically connected to the heating part 22 and the receiving coil 23 respectively. The current of the receiving coil 23 flows to the heating part 22 through the circuit control board 24, and the circuit control board 24 has the function of controlling the magnitude of the current and voltage and the heating time.

Please refer to FIG. 3 , the housing 21 is hermetically installed on the bottom of the cup body 10 , the heating part 22 is close to the bottom surface of the cup body 10 , and the receiving coil 23 is close to the bottom of the housing 21 .
