Description

Technical Field

[0002] Embodiments of the present invention relate to the technical field of beverage machines, and particularly to a beverage extraction device.

Background Art

[0004] At present, the packaging materials on both the front and back sides of a conventional general - structure beverage pack in the market are paper materials that can pass water and air. The ground coffee powder is encapsulated and fixed within the paper materials. Due to the water - passing and air - permeable properties of the paper beverage pack, it is not necessary to pierce the front and back during extraction. After water flows through the beverage pack, coffee extraction can be achieved. However, the structure of this type of pack makes it difficult to ensure high - pressure extraction of coffee powder within the pack, and rich coffee oil cannot be produced. The brewing device of this type of beverage extraction machine adopts a mechanical structure. Through the lever principle of the handle and the connecting rod, the front and back brewing cavities of the beverage pack are connected to compress the beverage pack. The defect is that a certain locking force is required to ensure that the beverage pack is completely compressed and sealed. Otherwise, water leakage and coffee leakage are likely to occur during the brewing process, or the handle rebounds. This is harmful to both the quality of the brewed coffee and the coffee machine. When the locking force is too large, the feel during handle closing is very bad, and the force required to open the handle after brewing is also very large.
