Coffee machine

The invention relates to a coffee machine which comprises a first body, a second body and an extraction assembly, and the first body is provided with a limiting part; the second body and the first body are in sliding connection in the height direction of the coffee machine, and the second body is provided with a limiting matching part; the extraction assembly is detachably connected to the second body; when the second body slides to the first state relative to the first body, the first body is used for limiting the extraction assembly to move in the height direction of the coffee machine; when the second body slides to a second state relative to the first body, the extraction assembly can move in the height direction of the coffee machine so as to be detached and separated from the second body; the limiting part can be matched with the limiting matching part, so that the movement of the second body in the height direction of the coffee machine is limited when the coffee machine is in a second state.
