The above-mentioned photo control program and temperature control program are generally provided on an integrated circuit IC of the main control board. The mode of controlling the heating mode of the heating component to end by the light control program can be that the light control program enables the heating circuit of the heating component to be disconnected to stop heating the coffee cup 2; or the light control program can switch the heating circuit of the heating component to the heat preservation circuit of the heating component or the heat preservation circuit set on the main control panel 4. The heating assembly may be a boiler including a boiler for heating and a thermal insulation heater for keeping warm. It is also possible to provide only one heater and then to heat and keep warm the boiling water by controlling the power. After the heating mode of the light-operated program control heating assembly is finished, when the distance measured by the light-operated distance measuring sensor 3 is greater than the preset anti-overflow distance, the main control panel enables the heating circuit of the heating assembly to be communicated again to restart the heating mode, if the distance measured reaches the preset anti-overflow distance, the heating is finished, and when the distance measured is greater than the preset anti-overflow distance, the heating mode is restarted, namely, intermittent heating is carried out until the temperature is preset to the main control panel 4.

If in the heating process, because the foam of coffee in the coffee cup is too much and rises quickly, but the temperature of coffee in the coffee cup does not reach the preset temperature of the main control board, the light-operated distance measuring sensor senses that the foam reaches the preset anti-overflow distance, and transmits information to the main control board, the main control board can control the heating circuit of the heating assembly to be switched off, and when the foam is reduced or the height of the foam is reduced, the heating circuit is switched on to start the heating mode, and the heating mode is switched on and off repeatedly until the foam is heated to the temperature set by the main control board, and finally, a signal is given to the main control board by the temperature sensing head to stop heating, and the heating work is finished.
