For example, the control device 6 controls the driving device 4 to drive the stirrer 32 to rotate, and the proportion of the milk foam is larger, namely the milk foam is thicker, the higher the rotating speed is and the longer the time is. The proportion and temperature of the milk foam are different for different customers and different drinks. The control device 6 controls the heating temperature and time of the heating device 5 and the rotating speed of the driving device 4, so that a user can obtain better experience.

When the heating device 5 and the driving device 4 work in coordination, it is preferable to use a slower rotation speed at low temperature and a faster rotation speed at high temperature, which allows air to be added to the milk at high temperature, which results in less expansion of the air bubbles and a finer milk foam effect. For another example, in the preparation of a formula or chocolate powder, a fast stirring operation is used to stir the materials in the cup evenly, and then a slow stirring operation is performed to prevent the beverage from foaming in the cup, and preferably, the user end can provide a selection key of the thickness (or amount) of the milk foam, and the selection key can change the rotation speed of the motor during the stirring process, and the faster the rotation speed is, the more air is taken into the cup by the stirrer 32, and the thickness of the milk foam is increased, and vice versa. When only the milk is heated, the control switch 11 can be switched off through the control device 6, so that the stirrer 32 is separated from the driving device 4, and the milk can be heated without generating milk bubbles.
