Description

Portable coffee filter cup structure and Italian coffee machine thereof Technical Field The utility model belongs to the technical field of coffee equipment, and particularly relates to a portable coffee filter cup structure and an espresso machine thereof. Background Along with the acceleration of the pace of life and the upgrading of consumption demands, portable coffee machines have become an important member in modern household kitchen appliances by virtue of the characteristics of light weight design, rapid operation and easy storage. The instant coffee making machine not only can meet the instant requirements of users on freshly ground coffee, but also optimizes the use experience through the design of the detachable filter cup, the modularized component and the like. However, the filter cup structure of the conventional portable coffee machine still faces various technical bottlenecks, such as poor extraction stability caused by insufficient adaptability to different powder amounts, single filter screen level affecting the quality of coffee liquid, inconvenient cleaning of powder residues and the like, which directly restrict pursuing of the taste of coffee by users and convenience of daily use. In the prior art, chinese patent publication No. CN204797591U discloses a semi-automatic coffee machine, which simplifies the coffee making process by the combined structure of a detachable water collecting tank, a filtering powder bowl and a coffee handle. Specifically, this scheme sets up the filter powder bowl in the coffee handle to utilize the filter screen to realize basic liquid-solid separation, concentrate the coffee residue through detachable water catch bowl simultaneously. However, this design suffers from the significant drawback that, firstly, the filter bowl is of a fixed structure, the filter screen is fixed in position, and it is difficult to adapt the powder pressing stroke according to the quantity of coffee powder. When the powder amount is small, the interval between the brewing net and the powder layer is too large, the high-pressure water flow easily causes coffee powder to splash, so that the extraction is uneven, and when the powder amount is too large, the brewing net is limited by a fixed stroke and cannot be fully pressed down, so that local overpressure and even blockage are easily formed. And secondly, the filter cup adopts a single-layer filter screen, and the coffee liquid directly flows out after only one-time filtration, so that the grease and the micro powder are not sufficiently separated, and the coffee taste is mellow and the thickness is not sufficient. In addition, the powder slag can be separated from the filter bowl only by manual knocking or pouring at a specific angle, and the operation is complex and easy to remain. Although partial improvement schemes try to improve the filtering effect by optimizing waterways or increasing the density of a filter screen, core problems of insufficient self-adaptability of a filter cup to powder amount, layered filtration deficiency of a liquid path and the like are not solved, and convenience of coffee quality and user operation is difficult to achieve. Disclosure of Invention Aiming at the problems in the related art, the utility model provides a portable coffee filter cup structure and an intentional coffee machine thereof, so as to solve the technical problems of insufficient self-adaptability of the existing filter cup to powder quantity, layered filtration loss of a liquid path and the like. The technical scheme of the utility model is that the portable coffee filter cup structure comprises a cup body with a hollow filter cavity, wherein the upper end of the cup body is provided with a powder inlet, the powder inlet is communicated with the filter cavity, and powder to be extracted enters the filter cavity from the powder inlet; The powder extraction device comprises a filter cavity, a powder extraction component, an elastic element, a powder extraction component and a powder extraction component, wherein the powder extraction component is arranged in the filter cavity and comprises a movable top plate and a support column arranged at the lower end of the movable top plate; The middle part top-down of movable roof is equipped with at least one first filter screen, the filter chamber bottom is equipped with the second filter screen, form between movable roof and the filter chamber bottom and mix the filtration space, the liquid that is extracted passes through each first filter screen in proper order, flows in mix the filtration space, again flows out after the second filter screen filters. According to the utility model, through the synergistic effect of the movable top plate and the elastic element, the self-adaptive adjustment of the brewing net stroke is realized, the problems of splashing when the powder amount is too small or blockage when the powder amount is too large are effectively avoided, and the extraction uniform
