1. A beverage dispenser having an identification device, the beverage dispenser comprising:
a body;
a heating device, which is installed on the body to realize a heating of the beverage in a pot by the heating device after the heating device is turned on;
the identification device, which is installed on the body and electrically connected to the heating device to realize the turning on or off of the heating device after the identification device identifies a type of the pot,
wherein the identification device comprises:
a sensor, configured to detect the type of the pot and emit a signal corresponding to the type of the pot, the sensor comprising a photosensitive sensor;
a control device, separately electrically connected to the sensor and the heating device, and configured to receive the signal emitted by the sensor and turn the heating device on or off according to the signal, the control device comprising:
a microcontroller chip, which is configured to receive and process the signal, connected to electricity and to a first ground terminal, and comprises a first microcontroller chip;
an isolation unit, which is electrically connected to the microcontroller chip, configured to turn the heating device on or off, and comprises a first isolation unit,
wherein the first isolation unit comprises an optocoupler, a first resistor and a second resistor, wherein one end of the first resistor is connected to the first microcontroller chip, the other end of the first resistor is connected to a first pin of the optocoupler, a second pin of the optocoupler is electrically connected, a third pin of the optocoupler is connected to the second resistor, and a fourth pin of the optocoupler is connected to a second ground terminal, so as to realize detection of light passing through the pot by the photosensitive sensor, a closing of the first isolation unit and turning on of the heating device, and to realize, conversely, a disconnection of the first isolation unit and turning off of the heating device.
