[0002] As living standards improve, people are paying more and more attention to their quality of life, and enjoying a cup of coffee in the morning or during leisure time has become a must for coffee lovers. Traditionally, coffee is made by pouring boiled water into a cup to brew coffee grounds. This method generally produces coffee with a mediocre taste, failing to satisfy those with discerning palates. Therefore, capsule coffee machines have gradually come into focus. However, existing capsule coffee machines are generally bulky and can only be used at home, making them inconvenient to carry around. This means that people cannot enjoy freshly brewed coffee anytime, anywhere when traveling.

[0003] To meet people's needs, people have invented some different styles of portable coffee machines. Although these portable coffee machines are small and easy to carry, different styles of portable coffee machines require different casings. The casings of different styles cannot be shared, which means that manufacturers need to produce multiple different casings, which is not conducive to reducing production costs.
