For most people, coffee has become an indispensable part of life. The role of coffee can be refreshed. According to research, it has many beneficial health benefits, such as reducing muscle fatigue, promoting secretion of digestive juice, and protecting. Heart and so on.

[0003]

There are many ways to brew coffee in general. For example, coffee beans are ground with coffee beans, and then extracted from coffee powder and hot water. The cooking can also be classified into five types: soaking method, boiling method, circulation method, Drip filtration method, siphon method, pressurization method, wherein the daily brewing method can adopt the trickling method, that is, the coffee powder is placed in a permeable container (ie, a filter bowl), and the filter paper is placed to prevent the powder from dripping into the extraction. Good coffee liquid. The coffee extracted through the filtered coffee powder and water has a more mellow taste. Although there are many factors affecting the quality of coffee brewing, including the quality of coffee beans, the time of filtration soaking, the brewing temperature, etc., however, the time of filtration soaking can be directly controlled by the brewer. In other words, the filter bowl, or the upper pot, required to filter the coffee powder is the main factor affecting the flow rate and smoothness of the coffee powder during filtration. The traditional filter cup structure has a cup shape, and has a filter hole therein. A filter paper is placed in the filter cup, and the coffee powder is placed on the filter paper, soaked in the filter paper by adding water, and then flowed into the drinking cup or punched through the filter hole. Inside the pot. However, the combination of the cup surface design of the conventional filter cup and the filter paper cannot adhere the filter paper to the cup surface completely when the water is injected, causing a gap between the filter paper and the cup surface of the filter cup to be excessively ventilated, so that the coffee flows into the filter. The flow rate of the holes is different, affecting the taste and concentration after extraction, and the quality of the coffee. In addition, the traditional filter bowl filter hole configuration is a simple round hole shape, can not effectively support the bottom of the filter paper, so that the coffee is soaked in the filter paper for too long, the same effect on the flow rate of coffee filtration, causing coffee too bitter, affecting coffee quality.
