[0033] When in use, the steam generator is connected via the steam inlet 131, and the bracket 10 is used as a fixing part. The rotating stirring frame 20 and the steam outlet 132 are both extended into the milk, and the steam quickly rushes into the wheel cavity 13 along the steam inlet 131 and sprays into the milk along the steam outlet 132, thereby playing the role of steam-assisted stirring. At the same time, due to the rapid flow of steam, the steam drives the impeller 40 to rotate, and the rotation of the impeller 40 drives the rotating shaft 30 to rotate, thereby driving the rotating stirring frame 20 to rotate in the milk. Through this solution, only one steam generator needs to be connected, which can not only drive the rotating stirring frame 20 to rotate and whip the milk, but also blow steam into the milk for auxiliary whipping. While the functions are complete, the overall structure is simpler and the cost is lower.
