[0002] An espresso machine is a type of coffee machine. Its principle is to use a mixture of high-pressure steam and water to quickly pass through the coffee layer and extract the coffee instantly. The coffee produced in this way has a high temperature, a low content of impurities such as caffeine, and a rich taste.

[0003] A traditional Italian coffee machine includes a heating unit and an extraction unit. The operator first places the coffee powder in the extraction unit and then installs the extraction unit in the coffee machine body.
