Therefore, the first conducting ring 6 and the second conducting ring 7 are used as positive and negative electrode interfaces of a circuit in the cup body 3, only when the first conducting ring 6 and the second conducting ring 7 are electrified simultaneously, the heating assembly and the circuit board in the cup body 3 can be electrified, the safety of the cup body 3 is further improved, and the cup body 3 or a human body is prevented from being damaged due to the fact that the conducting part on the bottom surface of the cup body 3 is directly electrified when being touched by a power supply by mistake.

In some conventional heating cups, the first conductive ring 6 and the second conductive ring 7 are both made of metal sheets, and the metal sheets are directly embedded in the bottom of the cup body 3. The process difficulty of directly embedding the conducting ring at the bottom of the cup is high, and when a producer with insufficient technical force adopts the structure to produce the heating cup, the position between the first conducting ring 6 and the second conducting ring 7 is difficult to keep accurate, and as the concentricity possibly has problems, the electrifying effect between the cup body 3 and the heating base 2 is influenced.

In this embodiment, the first conductive ring 6 and the second conductive ring 7 are plated on the surface of the PCB, and then the PCB is mounted on the base 4 of the cup 3 as a single module. Compared with the embedding process, the process on the PCB adopted in the embodiment is quite mature, the first conducting ring 6 and the second conducting ring 7 formed by the coating on the PCB can effectively ensure the accuracy of the position between the first conducting ring 6 and the second conducting ring 7, and meanwhile, the mature coating process is adopted to produce more conveniently and has lower defective rate.
