Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a portable capsule coffee machine. Background Art

[0002] In the traditional way of making coffee, generally, the boiled hot water is poured into a water cup to brew the coffee powder in the water cup. The coffee brewed in this way has a general taste and cannot meet the requirements of people with strict requirements for coffee taste. Therefore, capsule coffee machines have gradually come into people's sight.

[0003] The working principle of the capsule coffee machine is mainly to pierce the capsule through a puncture needle, and the water is transported to the capsule by a water pump to achieve extraction. For details, reference can be made to a portable coffee machine disclosed in the Chinese Patent Publication No. "CN217987307U".

[0004] At present, some designs of the puncture needle adopt a blade-type structure design. However, when the blade-type structure is punctured, the notch is relatively large, resulting in a large pressure loss inside the coffee capsule, thereby affecting the extraction efficiency of the coffee capsule and the coffee taste. There are also some puncture needles adopting a hollow columnar structure design, which can simultaneously complete the puncture of the capsule and the transportation of hot water. Since such puncture needles are generally movably arranged above the mounting seat and lack a corresponding support structure, the puncture needle has poor reset ability in the mounting seat, and is prone to swing during movement, resulting in poor puncture stability of the capsule. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies in the prior art, such as the lack of a corresponding support structure, resulting in poor reset ability of the puncture needle in the mounting seat, and to propose a portable capsule coffee machine.

A liquid outlet base 55 is detachably connected below the extraction cover 51.

[0036] In addition, in order to collect the extracted coffee, in this embodiment, a liquid receiving cup 6 is detachably connected to the bottom of the extraction unit 5. The liquid receiving cup 6 can be detachably connected to the outside of the extraction unit 5 by a snap connection method. A flexible pad is provided at the bottom of the liquid receiving cup 6, and the flexible pad can be a rubber pad or a sponge pad, which is used to improve the placement stability and protect the bottom of the liquid receiving cup 6.

[0037] In some embodiments, the piercing member 53 in the present utility model is a hollow member;

[0038] The piercing member 53 includes a cylindrical portion 531, a stepped portion 532 formed at one end of the cylindrical portion 531, and a pointed portion 533 formed at the other end of the cylindrical portion 531. A plurality of drain holes 534 communicating with the inner hole are provided on the pointed portion 533.

[0039] On the basis of the above embodiments, in this embodiment, the pointed portion 533 is a pyramid structure, and the drain holes 534 are formed on the inclined surface of the pyramid structure. In a further embodiment, the pyramid structure is a quadrangular pyramid. By designing four inclined surfaces at the end of the cylindrical portion 531, the ends of the four inclined surfaces are connected to each other to form a tip. Of course, in other embodiments, the inclined surfaces can also be set to other numbers.
