Description

Technical Field

[0001] The utility model relates to the technical field of coffee extraction, and more specifically, to a device for accurately grinding and quickly extracting coffee. Background Art

[0002] With the improvement of people's quality of life and the popularity of coffee culture in China, the performance of coffee grinding and extraction has become a key indicator for measuring the quality of coffee machines. Coffee grinding is a vital part of the coffee making process, which directly affects the flavor and taste of coffee. In terms of extraction, the coffee extraction machine forces hot water through the coffee powder under pressure, thereby more fully extracting the essence of the coffee powder. This pressurized extraction method not only improves the extraction efficiency, but also ensures that the taste of the coffee is consistent each time it is extracted.

[0003] After searching, the Chinese patent with the announcement number CN218794000U discloses a coffee extraction device, which can grind the unground coffee beans into powder through the grinding mechanism, and is provided with a screen, so that the unground coffee beans can remain in the grinding cylinder until they are ground into powder, which can make the grinding effect of the coffee beans better, and there will be no large coffee bean particles during the extraction process, which will lead to poor coffee bean extraction effect. In addition, the device directly puts the coffee beans into the grinding cylinder, thereby not causing waste of coffee.

[0004] However, when the above-mentioned coffee extraction device is actually used, its grinding mechanism lacks a closed structure during the grinding process of coffee beans, so the dust generated by grinding will be blown to the outside through the feed pipe. In addition, the screen provided at the bottom of the grinding mechanism is also prone to blockage, resulting in the inability to discharge the ground coffee powder inside the grinding cylinder, thereby making it difficult to discharge the coffee and affecting its use.
