[0035] At least two second power connection parts 8 are concentric rings, or one of the two second power connection parts 8 is a ring, and the other is a dot or a circular surface located at the center of the ring. By adopting the annular conductive method, the plug pin 6 can be electrically connected to the second power connection part 8 at any angle of the electric water cup 1, which plays a foolproof role, so that people can complete the purpose of power connection by placing the electric heating container 1 on the cup holder 3 at will.

[0036] As an embodiment, the pin portion 5 includes three pins 6, and the electric heating container 1 has three second power connection parts 8, the three circles of second power connection parts 8 are concentric rings, or two of the three second power connection parts 8 are concentric rings, and the other is a dot or circular surface at the center of the concentric rings.

[0037] A plurality of pins 6 and a second power connection part 8 are arranged in a concentric circle, so that different heating powers can be achieved by controlling the conduction between different conductors through the control board.

[0038] As an implementation method, one of the three pins 6 of the device is a signal pin, and the other two are positive and negative pins. The length of the signal pin is shorter than that of the positive and negative pins. The signal pin ensures that the positive and negative poles are connected to avoid safety problems caused by poor contact between the positive and negative poles.

[0039] The vehicle-mounted cup holder 2 has an opening 9, and at least a portion of the cup holder 3 passes through the opening 9. The first power connection portion 4 of the cup holder 3 can be connected to the vehicle-mounted power connection port. The first power connection portion 4 is a USB interface or a Type-C interface. The power cord is connected from the bottom of the vehicle-mounted cup holder 2 to the first power connection portion 4 of the cup holder 3. In this way, the power cord cannot be seen from inside the vehicle, and the space inside the vehicle is more tidy.

[0040] refer to Figure 10-12 The electric heating container 1 comprises a cup body 10, a cup bottom 11 and a heating plate 14. The cup body 10 and the cup bottom 11 are fixed. The electric heating container 1 has an installation cavity 12. The installation cavity 12 is located in the space enclosed by the cup body 10 and the cup bottom 11. The heating plate 14 is located in the installation cavity 12. The heating plate 14 is thermally connected or in contact with the bottom end surface of the cup body 10. When working, the cup body 10 is heated by the heating plate 14, and the heat is transferred to the internal liquid through the cup body 10.

[0041] As an embodiment, the heating container includes a mounting bracket 13, at least part of which is located in the mounting cavity 12, and the mounting bracket 13 is against the heating plate 14, so that the heating plate 14 is tightly against the bottom end surface of the cup body 10 through the mounting bracket 13.

[0042] As an implementation method, refer to Fig.10 The heating container includes a heat-insulating cotton 15, at least part of which is located between the heating plate 14 and the mounting bracket 13.

[0043] The device is provided with a convex rib 18 and a recessed portion 19 on the end surface portion 17. The convex rib 18 is used to press the heat insulation cotton 15 against the bottom of the heating plate, and the recessed portion 19 is used to provide a deformation space for the heat insulation cotton. The heat insulation cotton can deform toward the recessed portion to prevent the heat insulation cotton from being damaged by excessive extrusion force due to insufficient deformation space, and an air cavity is formed between the recessed portion 19 and the heating plate, which can play the role of air insulation, further reducing the heat conduction from the heating plate to components such as the PCB board.

[0044] The heating container includes a fixing frame 20, which includes an integrated or fixed annular frame 21 and a first mounting column 22. As an embodiment, the annular frame 21 and the first mounting column 22 can be fixed by welding. The annular frame 21 is fixed to the cup body 10, for example, by welding. The mounting bracket 13 has a first mounting groove 23 corresponding to the first mounting column 22, and the first mounting column 22 cooperates with the first mounting groove 23. During assembly, the first mounting column 22 is inserted into the first mounting groove 23, and then locked by screws to fix the mounting bracket 13 to the cup body 10.

[0045] The mounting bracket 13 has a second mounting column 24, the cup bottom 11 has a third mounting column 25, and the third mounting column 25 has a second mounting groove 26 that matches the second mounting column 24. During assembly, the cup bottom 11 is placed under the cup body 10, so that the second mounting column 24 is partially placed in the second mounting groove 26 of the third mounting column 25, and then the third mounting column 25 and the second mounting column 24 are fixed together by screws.

[0046] By adopting the above-mentioned assembly method, the cup bottom 11 and the cup body 10 form a whole, so that a flexible installation cavity 12 can be formed between the cup bottom 11 and the cup body 10, and components such as PCB and heating film can be more conveniently assembled in the installation cavity 12, while ensuring that the heating plate is tightly connected to the cup body, and the pressing effect is better.

[0047] As an implementation method, the heating plate can be formed by coating a nano-electric heating film on a substrate, which has a compact structure and high heating efficiency.

[0048] The cup holder 3 and the vehicle cup holder 2 can be fixed in the following ways: the cup holder 3 and the vehicle cup holder 2 are integrally arranged, or the cup holder 3 and the vehicle cup holder 2 are threadedly connected, or the cup holder 3 and the vehicle cup holder 2 are snap-connected, or the cup holder 3 and the vehicle cup holder 2 are fixed by screws, or the cup holder 3 and the vehicle cup holder 2 are welded, or the cup holder 3 and the vehicle cup holder 2 are glued.

[0049] This application scenario is an electric water cup in a car. The cup holder 3 is connected to the car cup holder 2 on the car, so that the cup holder 3 can be stably connected to the car, which is safer when people use it, and the cup holder 3 and the car form a fixed part, making the entire heating device simpler.

[0050] As an implementation method, refer to Fig.11 , Fig.12 The cup holder 3 includes a main body seat 27, one side of the main body seat 27 has a ring body portion 28, the peripheral side of the ring body portion 28 has a rotation buckle portion 29, one end of the ring body portion 28 has a first supporting surface 30, the vehicle cup holder 2 has an opening 9, the peripheral wall of the opening 9 is provided with a snap-fit ​​portion 32, one end of the opening 9 has a second supporting surface 33, the rotation buckle portion 29 is limitedly matched with the snap-fit ​​portion 32, and the first supporting surface 30 is in contact with the second supporting surface 33.

[0051] When installing the cup holder 3, align the ring body 28 with the opening 9, and then rotate the cup holder 3 so that the rotating buckle portion 29 and the snap-fit ​​portion 32 are buckled together, and the first support surface 30 and the second support surface 33 are abutted. The installation is simple and convenient, and the connection method is stable and reliable.
