Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a small coffee machine. Background Art

[0002] Nowadays, coffee machines are also one of the household appliances. When making coffee at home, the main raw materials are coffee powder and milk. In order to improve the taste of coffee, it is necessary to use high-temperature steam to make bubbles in the milk. In order to make the coffee more layered, it is best to extend the steam pipe to the bottom of the milk and froth the milk from bottom to top.

[0003] Since household coffee machines need to save space, the steam pipe is rotatably set on the coffee machine and its length cannot be too long. If the steam pipe is fixed and vertically set, it will interfere with the placement of the milk cup. The length of the steam pipe of the existing coffee machine is generally fixed. If there is less milk in the milk cup, the steam pipe cannot extend into the milk, and it is even more impossible to deeply process the milk from bottom to top. The milk cup is restricted by the top structure of the coffee machine and cannot move upward to allow the steam pipe to enter the milk cup more. Therefore, it is necessary to optimize the shortcomings of the coffee machine in processing milk. For this purpose, we propose a small coffee machine. Utility Model Content
