[0068] In this embodiment, the electric hot water cup of the present application that is convenient for assembly and production disposes the acceleration heat conduction plate 2 between the inner container 200 and the AC heating tube 3, which helps to quickly and evenly transfer the heat generated by the AC heating tube 3 to the entire bottom of the inner container 200, thereby greatly improving the heating rate and reducing the waiting time of the user. This also provides an AC heating method that can adapt to alternating current for the present application. Users can choose to use AC power or DC power for heating according to their needs, thereby greatly improving the applicability of the electric hot water cup of the present application that is convenient for assembly and production, and further facilitating the user to select the heating method.

The first conducting end of the thyristor BT1 is used to connect to the AC voltage, and the second conducting end of the thyristor BT1 is electrically connected to the AC heating tube 3.

[0096] In this embodiment, the thyristor output optocoupler IC1 can adopt an optocoupler, which has good electrical isolation performance, can effectively isolate the control circuit 53 and the high-voltage part, and improve the safety of the system. The signal from the control circuit 53 is received through the control end of the optocoupler, and then the conduction and cut-off of the thyristor BT1 are controlled to achieve precise control of the AC heating tube 3.

[0097] In addition, the function of the second resistor R15 is to limit the current of the thyristor BT1 output optocoupler to prevent damage to the optocoupler due to excessive current. At the same time, this resistor can also play a certain filtering role to reduce the noise interference in the circuit.
