Description

Technical Field

[0001] The utility model relates to the technical field of beverage brewing, in particular to a capsule brewing machine and a beverage capsule. Background Art

[0002] With the rapid development of modern beverage preparation technology, beverage brewing machines are widely welcomed by consumers due to their convenience and efficiency. Among them, coffee capsule brewing machines and capsule tea brewing machines, as typical representatives of beverage brewing machines, have greatly improved the convenience and quality of beverage brewing with their unique capsule packaging technology and one-button operation.

[0003] This type of brewing machine usually uses a precise water flow control system to accurately and quickly inject hot water into the capsule. In order to achieve uniform brewing of the beverage inside the capsule, a common practice in the prior art is to set a layer of perforated membrane inside the capsule. When hot water is injected into the capsule, the water will pass through this layer of perforated membrane and spray onto the beverage ingredients in a uniform and fine stream, ensuring that the beverage can be fully and evenly extracted. However, adding a layer of perforated membrane inside the capsule not only increases the manufacturing cost, but also makes the capsule packaging process more complicated, increasing the difficulty of production.

[0019] In summary, the utility model has the following beneficial effects:

[0020] First, the utility model adopts the design of a water injection pipe with holes on the outer periphery. When the water injection pipe is inserted into the capsule to inject water, water can be evenly injected and brewed around the capsule through the water injection holes on the periphery, so that the beverage can be brewed evenly. It is no longer necessary to encapsulate a layer of perforated film in the capsule, which reduces the cost and the difficulty of capsule packaging.

[0021] Secondly, the utility model uses an electromagnet to attract and control the water injection pipe to pierce the top membrane of the capsule downwards, the piercing speed is faster, and compared with the use of a telescopic motor, the structure is simpler, and the manufacturing cost of the capsule brewing machine can be reduced.
