[0037] The American drip function module of the coffee machine includes a detachable drip kettle, a metal filter basket and a coffee basket. The drip kettle is made of transparent glass material, which facilitates the user to observe the water level and the coffee brewing process. Meanwhile, the brewing assembly inside the drip kettle is provided with a coffee basket for placing the filter basket and coffee powder. The filter screen is designed to be fine and dense, which effectively filters the coffee residue. The brewing assembly upper cover above the brewing assembly is distributed with a plurality of shower holes, which allows the coffee in the filter basket to be evenly brewed, thereby ensuring that the dripped coffee has a pure and fragrant taste. The bottom of the brewing assembly above the position is provided with a water stop structure. Only when the drip kettle is placed in place, the water outlet will be water-conducting. Otherwise, the umbrella-shaped silica gel will be sealed.

[0038] In the American drip function module state of the coffee machine, hot water enters the drip hot water channel and the center hot water channel of the hot water channel in the brewing assembly upper cover, and is then dispersed and flowed out through the small holes. When the drip kettle is pushed forward, the cup cover of the drip kettle pushes away the water stop seat, the water stop silica gel is opened, and the coffee flows into the cup. When the drip kettle is taken out, the water stop seat is reset under the action of the spring and remains horizontal, and the water stop silica gel is closed.
