Description

Technical Field

[0001] The utility model relates to a beverage brewing and extraction device, in particular to a cup suitable for capsule beverage extraction, which can be applied to capsule beverages such as traditional Chinese medicine, tea, and coffee. Background Art

[0002] With the continuous development of the capsule beverage (traditional Chinese medicine, tea, coffee) market and the continuous introduction of various beverages, many capsule beverage production devices have emerged on the market. Capsule traditional Chinese medicine machines or capsule coffee machines, as a more simple and convenient brewing equipment, have always been loved by people. Its working principle is to put the capsule cup into the capsule machine chamber, then close the chamber, and the upper and lower tubular needle ports in the chamber simultaneously pierce the capsule, and then high-pressure hot water is injected into the capsule to extract a cup of fresh beverage.

[0003] However, currently common capsule traditional Chinese medicine machines or capsule coffee machines are generally indoor machines, with a large and bulky body, inconvenient to carry, and generally placed in a fixed place for use. It cannot meet the needs of users to brew beverages anytime and anywhere. In response to this situation, some portable capsule beverage production devices have emerged on the market, but most of the production devices are manual operations, that is, by manually pressing the piston rod on the machine body multiple times to provide high-pressure water for brewing. Since the high-pressure water for brewing needs to be obtained through manual operation by the user, it causes a certain operation burden to the user. Moreover, this type of production device has a relatively complex production process and a long operation time, and cannot meet the needs of people to quickly obtain the required beverages.

[0004] Therefore, several improved brewing cups are disclosed in the prior art, such as the Chinese utility model patent "Portable Capsule Beverage Brewing Cup and Portable Beverage Brewing Cup" with the patent number ZL201621001054.0 (the authorized announcement number is CN206403624U); reference can also be made to the Chinese invention patent "Portable Coupled Capsule Beverage Brewing Cup and Portable Coupled Beverage Brewing Cup" with the patent number ZL201611129161.6 (the authorized announcement number is CN106820973B); the Chinese invention patent "A Flexible Container and a Film-Type Capsule Beverage Cup" with the patent number ZL201710213672.4 (the authorized announcement number is CN107048921B).
