[0002] With the development of society and the improvement of people's lives, coffee has become one of the indispensable drinks in people's daily lives, and coffee machines have gradually entered people's lives and work environments. Conventional coffee machines generally extract coffee powder through steam to obtain coffee liquid, which mainly include a grinding device and a steam generating device. The powder outlet of the grinding device is connected to the opening of the extraction cup so that the coffee powder processed by the grinding device can directly fall into the extraction cup, and the steam outlet of the steam generating device is also connected to the extraction cup so that the steam can be directly transported to the extraction cup. The coffee can be made by steam extraction, and people can use a container to receive the coffee in the extraction cup.

[0003] The problem is that since the grinding device and the steam generating device are both connected to the extraction cup, when the steam is released, it can enter the grinding device through the powder outlet.
