Description

Portable coffee machine {Portable coffee machine}

The present invention relates to a portable coffee machine, and more particularly, to a portable coffee machine that can easily drink coffee capsules by heating water in a plastic bottle anytime, anywhere.

Recently, as living standards increase, the number of people who drink coffee beans rather than instant coffee is increasing.

These coffee beans are drunk in the form of espresso in which coffee is extracted in a short time by providing hot water at high pressure to ground coffee beans, or by mixing hot water with espresso, or by mixing milk and the like with espresso.

As the coffee culture has become more luxurious, drip coffee provided by baristas is gaining popularity. Drip coffee refers to coffee that is brewed with freshly ground coffee beans and brewed with hot water slowly by hand.

In order to meet the demand of ordinary people to drink coffee, products that are convenient to drink, such as pod coffee and various capsule coffees, have been released, but these pod coffees are ground coffee beans into coffee powder and sealed in small cups or packs. As a result, the demand for coffee is increasing in recent years due to the fact that the coffee has a very fragrant taste and can be consumed easily because it prevents the problem that general coffee beans or coffee powder are damaged or oxidized in contact with air.

However, in order to extract and drink pod coffee or capsule coffee, a coffee extractor that is bulky, heavy, and inconvenient to handle is required, so its use is limited outdoors.

In consideration of this, some portable coffee machines that are portable and capable of extracting coffee by grinding coffee beans have been proposed, and these portable coffee machines are composed of a machine body and a grinder that is built-in to the machine body and grinds coffee beans. , It is a product that puts coffee beans, receives ground coffee powder by a glider, and extracts coffee from a drip machine for drinking.

However, the conventional portable coffee machine is inconvenient to use because it has to be provided with a separate drip machine, and since it has a complicated structure equipped with a grinder, etc., it is difficult to carry in terms of weight or handling.
