Extraction assembly of coffee machine and coffee machine

Abstract

The extraction assembly comprises an extraction bowl body, the extraction bowl body is provided with an extraction cavity and an extraction net, the extraction net is arranged at the bottom end of the extraction cavity, an extraction interval is formed between the extraction net and the bottom wall of the extraction cavity, and a liquid outlet hole is formed in the bottom end of the extraction bowl body; the liquid outlet hole is used for guiding the extraction liquid in the extraction interval out; the extraction base covers the bottom end of the extraction bowl body in a sealing manner; a gas guide interval is formed between the extraction base and the bottom surface of the extraction bowl body; the extraction base is provided with a liquid outlet channel and an air inlet, and the liquid outlet channel and the liquid outlet hole are correspondingly arranged and communicated; a foaming net is arranged in the liquid outlet channel; one end of the air inlet is communicated with the outside, the other end of the air inlet is communicated with the air guide interval, and the air guide interval is communicated between the liquid outlet channel and the liquid outlet hole. In the coffee extraction process, extraction liquid in the liquid outlet channel can be guided into gas of the gas guide interval through the gas inlet to be matched with the bubbling net to achieve bubbling, and the extraction liquid is denser.
