The invention discloses a coffee machine. The coffee machine comprises a grinding chamber with a grinding cavity, a grinding device, a hot water supply device communicated with the grinding cavity, anelectric control device for controlling the grinding device and the hot water supply device to work, and a filter net structure, wherein the grinding device comprises a grinding tool set arranged inside the grinding cavity and a motor arranged outside the grinding cavity, the filter net structure comprises a first filter net body annularly arranged around the grinding tool set and a second filternet body at least annularly arranged around the lower portion of the first filter net body, the lower ends of the first filter net body and the second filter net body are in sealed connection with the bottom wall of the grinding cavity so that the grinding cavity can be divided into a bean grinding cavity, a secondary filtering cavity around the bean grinding cavity and a beverage cavity around the secondary filtering cavity. According to the technical scheme, in the coffee stirring process, coffee particles can be limited from passing through the filter net, and therefore the coffee beveragequality is improved.
