However, the conventional integrated grinding type coffee cup only has a brewing function, and only can be used for directly watering hot water to be sprinkled on ground coffee powder to brew dissolved substances in the coffee powder. For example, in the currently available patent publication nos. CN 209574402U and CN 213248454U, when reference is made to grinding and brewing coffee beans, the container for holding coffee powder must be taken out of the coffee cup body after the coffee beans are ground into powder, and then the coffee powder is brewed by injecting water into the upper portion of the container. Although the grinding structure of the coffee beans is integrated in the cup body, the two products obviously cannot perform the steam extraction function similar to that of espresso coffee and cannot extract grease in the coffee, in addition, the traditional espresso coffee adopts overhigh steam extraction temperature, certain taste damage is caused to drinking ingredients in coffee powder, the water temperature for extracting the coffee is between 90 ℃ and 95 ℃, and the traditional grinding type integrated coffee cup cannot easily control the temperature of water during coffee brewing, so that the taste is often influenced. In addition, when the products in the above two patents are used, the ground coffee powder filtering container needs to be detached from the integrated coffee cup manually, which not only may cause the coffee powder to be scattered, but also may cause pollution to the coffee powder in the brewing process. In addition, when the traditional integrated coffee grinding cup is used, the grinding part needs to be cleaned independently after the use, otherwise, coffee powder can remain in gaps of the coffee bean grinding structure, the residual coffee powder can deteriorate quickly, if the coffee grinding cup is not cleaned, the coffee powder can be mixed in new coffee powder to be brewed into the cup body when the coffee cup is used next time, the taste of coffee is influenced, and therefore the grinding part needs to be cleaned independently by the traditional integrated grinding coffee cup, and the use is inconvenient.
