With the improvement of the quality of life, after work, coffee has become the drink of choice for many office workers to improve work efficiency, buffer work pressure and take a break. However, due to the inconvenience of making coffee and the high price of purchasing a coffee machine, many people choose to go out to a coffee shop to buy coffee, but this will cause inconvenience to office workers who are far away from the coffee shop. Maybe the coffee has been cold, affecting the taste. What's more, the price of buying coffee in the store is generally more expensive. For ordinary office workers, coffee can only be an aristocratic drink they occasionally taste, and frequent purchases inevitably cost a lot of money.

Although some people now buy their own coffee machines and make their own coffee. However, in addition to the above-mentioned high price, the existing coffee machine has great inconvenience in use. Generally, it can only brew a single type of coffee, or can only brew coffee, but cannot be used for other beverages; On the other hand, the existing coffee machines are also relatively large in size, generally only suitable for home use, not suitable for carrying out. Even if they can be carried out, it is inconvenient to add and boil water; It is inconvenient to disassemble and clean, resulting in the limitation of "three minutes for preparation and half an hour for cleaning", so many people can only abandon it.
