Description

Technical Field

[0001] The invention relates to the technical field of coffee machines, in particular to a high-precision raw material feeding structure for a vertical capsule coffee machine. Background Art

[0002] Coffee is one of the three major beverages in the world. People all over the world love coffee more and more. And the increasing popularity of coffee machines makes the preparation of coffee more convenient and simple. The resulting "coffee culture" fills every moment of life. Capsule coffee machines are a type of coffee machine. The so-called capsule is that the manufacturer pre-loads the coffee powder into a plastic capsule similar to a pudding box, and then fills it with inert gas to keep it fresh.

[0003] The extraction actuator of the extraction station of the capsule coffee machine includes an extraction head and a capsule cup. The capsule cup is used to support and fix the capsule during extraction. During extraction, the extraction head and the capsule cup are pressed against each other to fix the capsule. The extraction needle fixed on the extraction head pierces the capsule package, and water is injected into it for extraction. The extracted coffee is then collected in a beverage cup. After the extraction is completed, some residual coffee liquid will adhere to the extraction needle, which may cause contamination to the coffee liquid after long-term use. At the same time, different coffee liquids may cross-flavor each other, affecting consumers' use. Summary of the invention
